[0012] Beneficial effects of the utility model:

[0013] (1) In the present invention, a No. 1 clamp frame and a No. 2 clamp frame are set to load materials at the same time. When the workpiece on the No. 1 clamp frame is being ground with threads, the workpiece on the No. 2 clamp frame will also be ready. After the No. 1 clamp frame completes the grinding work, the screw will be rotated by the screw motor. While the screw is rotating, the thread on the outer side of the screw and the threaded connection of the screw slider slide toward the front side of the workbench, leaving a working space for the No. 2 clamp frame. The electric slider of the No. 2 clamp frame will slide the entire No. 2 clamp frame to the front side of the grinding wheel frame through the sliding connection with the left and right slide rails of the workbench. Then the lifting cylinder drives the transmission rod to descend, and the workpiece clamping area of ​​the No. 2 clamp frame descends until it reaches the grinding wheel grinding area. Then the grinding wheel will be rotated by the grinding wheel motor, and the grinding wheel seat will also slide left and right through the sliding connection with the guide rail to grind the external thread of the workpiece.

[0014] (2) In the utility model, the No. 1 supporting block and the No. 2 supporting block are provided to play a supporting role when the workpiece is ground by the grinding wheel. At the same time, because the structure of the thread is likely to produce iron filings remaining on the workpiece during the grinding process, the workpiece will rotate back and forth in the semicircular groove on the supporting block when the workpiece is rotated by the rotating motor. The nano sponge layer in the semicircular groove will rub the iron filings on the surface of the workpiece to clean the iron filings in the thread, thereby ensuring the processing quality of the thread.

[0015] (3) In the utility model, a detection frame is set up to check the processed workpiece. The processed workpiece is placed in the detection frame. The light of the LED lamp will shine through the organic glass plate to the workpiece in the frame. The light shines from the back of the workpiece, so that the contour of the thread edge of the workpiece after processing is outlined. The unevenness or defects on the surface of the workpiece will form an obvious light and shadow contrast, which helps the inspector to identify the problem more accurately.

[0016] In summary, the device has the advantages of improving production efficiency, reducing labor costs, ensuring processing quality, and more conveniently detecting thread defects, and is particularly suitable for the field of thread grinder technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Furthermore, a slide 31 is provided at the lower end of the No. 1 clamp frame 3, and a screw slider 311 is provided on the lower sides of the left and right ends of the slide 31.

Because during the grinding process, iron filings are easily generated on the workpiece due to the structure of the thread, and the workpiece will rotate back and forth in the semi-circular groove 6 on the supporting block when the No. 1 rotating motor 321 and the No. 2 rotating motor 421 are rotated, the nano-sponge layer in the semi-circular groove 6 will rub the iron filings on the surface of the workpiece to clean the iron filings in the thread, thereby ensuring the processing quality of the thread.

[0032] Working process: first, place the workpiece on the No. 1 fixture frame 3 and the No. 2 fixture frame 4 respectively. The No. 1 cone fixing frame 322 and the No. 2 cone fixing frame 422 will respectively press against the left and right sides of the workpiece to fix the workpiece. Then the grinding wheel 233 will be rotated by the grinding wheel motor 234, and the grinding wheel seat 23 will also slide left and right through the sliding connection with the guide rail 221 to grind the external thread of the workpiece on the No. 1 fixture frame 3. When the No. 1 fixture frame 3 completes the grinding work, it will rotate the screw 121 through the screw motor 123. While rotating the screw 121, the thread on the outside of the screw 121 is connected to the thread of the screw slider 311 to slide toward the front side of the workbench 1, leaving working space for the No. 2 fixture frame 4. The electric slider 412 of the No. 2 fixture frame 4 will be connected to the left and right slide rails 13 of the workbench 1 through the sliding connection. , slide the entire No. 2 clamp frame 4 to the front side of the grinding wheel frame 2, and then the lifting cylinder 41 drives the transmission rod 411 to descend, and the workpiece clamping area of ​​the No. 2 clamp frame 4 descends until it reaches the grinding area of ​​the grinding wheel, and then the grinding wheel 233 grinds the workpiece on the No. 2 clamp frame 4. At this time, the workpiece to be processed has been placed on the No. 1 clamp frame 3, and the No. 1 clamp frame 3 and the No. 2 clamp frame 4 reciprocate back and forth for processing. At the same time, the No. 1 supporting block 33 and the No. 2 supporting block 43 play a supporting role when the workpiece is ground by the grinding wheel. At the same time, because the structure of the thread is prone to iron filings remaining on the workpiece during the grinding process, the workpiece will rotate back and forth in the semicircular groove 6 when it is ground and rotated, and the nano sponge layer in the semicircular groove 6 will rub the iron filings on the surface of the workpiece to clean the iron filings in the thread to ensure the processing quality of the thread.

[0033] Secondly, place the processed workpiece into the inspection frame 5, and the light from the LED tube will shine through the plexiglass plate 51 to the workpiece in the frame. The light shines from the back of the workpiece, so that the contour of the thread edge of the workpiece after processing is outlined. The unevenness or defects on the surface of the workpiece will form an obvious light and shadow contrast, which will help the inspector to identify the problem more accurately.
