Abstract

The present invention relates to a conveying accuracy related fault detectable integrated sheet body punching and grinding assembly, including frame, conveying trough seat and processing frame. The processing frame is provided with a punching device and a grinding device, the frame is provided with a feed motor and feed screw. The feed screw is sleeved with a movable feed block; the movable feed block is fixedly connected with a movable feed seat, and the movable feed seat is provided with a feed lift cylinder, the feed lift cylinder is provided with a feed lift block. The feed lift block is evenly disposed with feed blocks that are capable of passing through the feed conveying trough, and a vertically oriented beam emitter is disposed on the portion that the feed lift block corresponds with the grinding device. A beam receiver is embedded in the lower surface of the grinding component of the grinding device; the present invention provides a beam emitter capable of emitting a vertical beam on the feed block corresponding to the grinding device, matching with the beam receiver disposed under the grinding head of the grinding device, which may accurately detect the feeding position of the feed block, thereby improves the punching and grinding precision of sheet bodies.

First claim

What is claimed is:

1. A conveying accuracy related fault detectable integrated sheet body punching and grinding assembly, comprising:
a frame;
a conveying trough seat disposed upon said frame and upon which a sheet to be punched is mounted above a feed trough defined within said conveying trough seat;
a processing frame disposed upon said conveying trough seat and having a punching device disposed at a punching station for punching a hole within the sheet, and a grinding device disposed at a grinding station for grinding internal peripheral portions of the hole punched within the sheet by said punching device;
a feed motor operatively connected to a feed screw which is sleeved within a plurality of movable feed blocks;
said plurality of movable feed blocks are operatively connected to a movable feed seat;
said movable feed seat is provided with a feed lift cylinder which is operatively connected to a feed lift block;
a plurality of feed blocks, which are movable through said feed trough, are disposed upon said feed lift block for moving the sheet between said punching station and said grinding station;
a vertically oriented beam emitter is mounted within said feed lift block for emitting a beam signal; and
a beam receiver is mounted within said grinding device so as to receive said beam signal from said beam emitter and thereby ensure that the sheet is precisely positioned with respect to said punching device such that the hole may be accurately punched within the sheet.

2. The conveying accuracy related fault detectable integrated sheet body punching and grinding assembly of claim 1 , wherein:
each one of said plurality of feed blocks comprises an L-shaped block having a vertical portion and a horizontal portion having a predetermined length dimension which corresponds with a length dimension of the sheet;
a discharging opening is defined within at least one of said plurality of feed blocks so as to receive that portion of the sheet which has been punched out from the sheet by said punching device located at said punching station;
a collection port is defined with said feed lift block and is connected with said discharging opening;
a collection box is connected to said collection port for collecting portions of the sheet that have been punched out from the sheet by said punching device and conducted through said discharging opening and said collection port; and
said beam emitter can emit a vertical beam that coincides with a longitudinal axis defined by said discharging opening.

3. The conveying accuracy related fault detectable integrated sheet body punching and grinding assembly of claim 2 , wherein:
a lift height detection device is mounted upon said processing frame within the vicinity of said punching device; wherein said lifting height detection device comprises a lifting height detection cylinder disposed beneath said processing frame, a lift height detection block operatively connected to said lift height detection cylinder and comprising an inverted U-shaped block with a horizontal portion thereof located at upper ends of vertical portions thereof;
a first contact sensor is disposed beneath said horizontal portion of said lift height detection block;
a width dimension of said vertical portions of said lift height detection block corresponds to a width dimension of said conveying trough seat;
a central upper portion of said lift height detection block operatively cooperates with said feed trough so as to allow said plurality of feed blocks to pass through said feed trough; and
second contact sensors are embedded within lower end portions of said vertical portions of said lift height detection block so as to ensure that said lift height detection block is disposed at a predetermined elevation relative to said conveying trough seat.

4. The conveying accuracy related fault detectable integrated sheet body punching and grinding assembly of claim 2 , wherein:
a pair of collection assembly motors are disposed upon said movable feed seat;
each one of said pair of collection assembly motors has a vertically oriented upstanding assembly rotary shaft connected thereto;
external peripheral surface portions of each one of said pair of collection assembly rotary shafts is sleeved within a collection assembly rotary sleeve;
upper end portions of each one of said collection assembly rotary sleeves is disposed within a rotary sleeve bearing housing which is mounted upon an undersurface portion of said feed lift block;
an external peripheral surface portion of each one of said collection assembly rotary shafts is disposed within a vertically oriented rotating shaft annular tube which includes a rotary shaft mating plug such that each one of said rotary shaft mating plugs is radially interposed between one of said collection assembly rotary shafts and one of said collection assembly rotary sleeves;
a lower end portion of each one of said collection assembly rotary sleeves is fixedly mounted within a rotary collection support block such that said rotary collection support blocks are disposed opposite one another; and
said collection box is mounted upon said rotary collection support collection blocks.

5. The conveying accuracy related fault detectable integrated sheet body punching and grinding assembly of claim 1 , wherein:
said grinding device includes a grinding lift cylinder disposed beneath said processing frame;
a grinding lift base is connected to a bottom portion of said grinding lift cylinder;
a grinding motor is disposed beneath said grinding lift base;
a grinding head is operatively connected to said grinding motor;
wherein said grinding lift base is operatively connected to a grinding press block which is engaged with a punched sheet disposed upon one of said plurality of feed blocks by grind buffer springs;
said grinding head cooperates with said grinding press block so as to maintain the sheet in a stable position upon said one of said plurality of feed blocks;
a lower end portion of said grinding head is tapered so as to facilitate engagement of said grinding head within the hole punched within the sheet; and
said beam receiver is embedded within a central lower surface portion of said grinding head.

6. The conveying accuracy related fault detectable integrated sheet body punching and grinding assembly of claim 1 , wherein:
said punching device comprises a punching cylinder mounted upon said processing frame;
said punching cylinder is operatively connected with a punching press block which is adapted to engage the sheet disposed upon said conveying trough seat;
