Technical Field

[0001] The invention relates to the technical field of processing jigs, in particular to a multi-purpose batch processing jig. Background Art

The T-slot is arranged on the front end surface of the base plate, the T-slider is fixed on the lower surface of the workpiece placement plate, and the T-slider is assembled in the T-slot, the fastening bolt is arranged on the upper pressure plate, and the lower end of the fastening bolt passes through the upper pressure plate and the workpiece placement plate and extends into the positioning hole. The positioning hole is arranged on the upper surface of the base plate. This design realizes the overall disassembly and assembly function of the workpiece, and the fine-tuning knob is arranged on the left end surface of the support plate.

A positive and negative threaded screw 6 is movably connected to the inner side of the rotating seat 2. The two sets of threads on the outer sides of the positive and negative threaded screw 6 are mirror-imaged to ensure that the two clamping plates 3 can clamp the workpiece 37 when the positive and negative threaded screw 6 rotates. The two clamping plates 3 are both screwed to the outer sides of the positive and negative threaded screw 6, and the rotation of the positive and negative threaded screw 6 drives the two clamping plates 3 to clamp the workpiece 37.

The rotation of the first gear 22 drives the transmission gear 27 to start rotating. The rotation of the transmission gear 27 drives the pulley 28 to start rotating. Since the belt 10 is connected to the pulley 28 and the connecting wheel 11, during the rotation of the pulley 28, the connecting wheel 11 will also start to rotate.

[0034] Embodiment 2:

[0035] On the basis of Example 1, in order to prevent the two groups of clamping plates 3 from moving outward during the processing, the two groups of clamping plates 3 are movably connected with guide rods 4 on both sides, and both ends of the guide rods 4 are fixedly connected to the inner side of the rotating seat 2, and the clamping plates 3 are guided by the guide rods 4. The locking mechanism includes a connecting ring 18, which is sleeved on the outside of the groove 21, and the connecting ring 18 is slidably connected in the connecting cavity 32. One end of the connecting ring 18 is fixedly connected with two groups of L-shaped pressure rods 17, and the end of the L-shaped pressure rod 17 away from the connecting ring 18 extends into the external environment. A plurality of groups of limiting holes 20 are opened in one side of the groove 21, and the end of the connecting ring 18 close to the limiting hole 20 is fixedly connected with two groups of locking blocks 19. The locking blocks 19 The connecting ring 18 is clamped in the limiting hole 20, and one end thereof away from the L-shaped pressure rod 17 is fixedly connected with the first spring 31, and the other end of the first spring 31 is fixedly connected with the connecting cavity 32. When the second square rod 8 moves, the second pressure plate 29 is driven to move, and when the first square rod 9 moves, the first pressure plate 35 is driven to move. When the first pressure plate 35 and the second pressure plate 29 are in contact with the corresponding L-shaped pressure rod 17, as the first pressure plate 35 and the second pressure plate 29 move, the L-shaped pressure rod 17 moves inward and drives the connecting ring 18 to move. The movement of the connecting ring 18 drives the locking block 19 to disengage from the corresponding limiting hole 20, and at this time, the positive and negative thread screws 6 are in a movable state.

[0036] The first square rod 9 is slidably connected to the square groove 30 on the right side, and the outer side of the first square rod 9 is sleeved with a limit ring 15, and the limit ring 15 is slidably connected to the guide groove 34. The guide groove 34 is opened in the square groove 30 on the right side. The outer side of the first square rod 9 is sleeved with a second spring 33, and one end of the second spring 33 is fixedly connected to the guide groove 34, and the other end is fixedly connected to the limit ring 15. The transmission mechanism includes a transmission gear 27, and the transmission gear 27 is movably connected to the connecting block 12. A pulley 28 is fixedly connected to one side of the transmission gear 27, and the pulley 28 is movably connected to the connecting block 12. The pulley 28 is connected to the connecting wheel 1 through the belt 10. 1, the connecting wheel 11 is fixedly connected to the screw rod 14, and the connecting wheel 11 is arranged in the connecting block 12. When the side of the workpiece 37 needs to be processed, the second square rod 8 is pulled backward to drive the first gear 22 connected thereto to mesh with the transmission gear 27. The first gear 22 is driven to rotate by rotating the second square rod 8. The first gear 22 drives the transmission gear 27 to rotate. The transmission gear 27 drives the pulley 28 to rotate. Since the belt 10 is connected to the pulley 28 and the connecting wheel 11, the connecting wheel 11 will also start to rotate during the rotation of the pulley 28.

[0037] A U-shaped clamping rod 23 is provided on one side of the first gear 22, and the U-shaped clamping rod 23 is slidably connected to the cavity 24. The cavity 24 is opened in the connecting block 12, and a plurality of groups of clamping holes 26 are opened in the transmission gear 27 near one end of the U-shaped clamping rod 23. The U-shaped clamping rod 23 is clamped in the clamping hole 26. Two groups of connecting springs 25 are fixedly connected in the cavity 24, and the other end of the connecting spring 25 is fixedly connected to the U-shaped clamping rod 23. After the first gear 22 is meshed with the transmission gear 27, the U-shaped clamping rod 23 will be pushed to move inward. At this time, the U-shaped clamping rod 23 clamped in the clamping hole 26 will be disengaged, so that the transmission gear 27 is in an active state. When it is flipped to a suitable position, the second square rod 8 is released. Under the elastic force of the connecting spring 25, the U-shaped clamping rod 23 will be clamped into the corresponding clamping hole 26, so that the transmission gear 27 cannot rotate.

[0038] Working principle: when in use, several groups of workpieces 37 that need to be processed are inserted into the upper end of the positioning rod 5. After the insertion is completed, the second square rod 8 is pushed inward to make its plug-in end inserted into the square groove 30 on the right. When the second square rod 8 enters the square groove 30 on the right, at this time, with the movement of the second square rod 8, the first square rod 9 located in the square groove 30 on the right will be driven to move to the left until it enters the square groove 30 on the left. At the same time, when the second square rod 8 moves, it will drive the second pressing plate 29 to move, and when the first square rod 9 moves, it will drive the first pressing plate 35 to move. When the first pressing plate 35 and the second pressing plate 29 contact the corresponding L-shaped pressing rod 17, at this time, with the movement of the first pressing plate 35 and the second pressing plate 29, the L-shaped pressing rod 17 will move inward and drive the connecting ring 18 to move. The movement of the connecting ring 18 will drive the locking block 19 to disengage from the corresponding limiting hole 20. At this time, the positive and negative thread screws 6 are in an active state;

[0039] The right-hand positive and negative threaded screw 6 starts to rotate by rotating the second square rod 8. When the right-hand positive and negative threaded screw 6 rotates, the left-hand positive and negative threaded screw 6 starts to rotate through the first square rod 9. Since the two groups of positive and negative threaded screws 6 are both screwed with two groups of clamping plates 3 on the outside, the two groups of clamping plates 3 will move inward to clamp the workpiece 37 when the positive and negative threaded screws 6 rotate. After clamping, the second square rod 8 is pulled out of the square groove 30 on the right side. At this time, under the elastic force of the second spring 33, the first square rod 9 returns to its original position. Under the elastic force of the first spring 31, the connecting ring 18 returns to its original position, so that the locking block 19 is inserted into the corresponding limiting hole 20, so that the positive and negative threaded screw 6 is limited and fixed, ensuring that the two groups of clamping plates 3 can no longer move, and the outer side and upper end of the workpiece 37 are processed through a plurality of groups of through holes 36.

[0040] When it is necessary to process the side of the workpiece 37, the second square rod 8 is pulled backward to drive the first gear 22 connected thereto to engage with the transmission gear 27. After the first gear 22 engages with the transmission gear 27, the U-shaped clamping rod 23 will be pushed to move inward. At this time, the U-shaped clamping rod 23 clamped in the clamping hole 26 will be disengaged, so that the transmission gear 27 is in an active state. By rotating the second square rod 8, the first gear 22 starts to rotate, and the first gear 22 rotates to drive the transmission gear 27 to rotate. The transmission gear 27 rotates to drive the pulley 28 to rotate. Since the belt 10 is connected to the pulley 28 and the connecting The connecting wheel 11 is connected to the workpiece 37, so during the rotation of the pulley 28, the connecting wheel 11 will also start to rotate. At this time, the screw rod 14 will rotate and drive the connecting gear 13 to rotate. The rotation of the connecting gear 13 can drive the rotating seat 2 to flip over. When it is flipped to a suitable position, the second square rod 8 is released. Under the elastic force of the connecting spring 25, the U-shaped clamping rod 23 will be clamped into the corresponding clamping hole 26, so that the transmission gear 27 cannot rotate. At this time, the side of the workpiece 37 can be processed. After the processing is completed, the rotating seat 2 is rotated to a horizontal position according to the above method, and the two sets of clamping plates 3 are opened to take out the workpiece 37 after the processing is completed.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
