Description

Technical Field

[0001] This invention relates to the field of machining fixture technology, specifically a multi-purpose batch machining fixture. Background Technology

[0002] For example, Chinese patent CN107855801A discloses a CNC batch processing fixture, including a T-slot, a T-slider, a fastening bolt, a positioning hole, a fine-tuning knob, a groove, a lead screw, and a nut seat. The T-slot is opened on the front end face 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 set 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 opened on the upper surface of the base plate. This design realizes the overall assembly and disassembly function of the workpiece. The fine-tuning knob is set on the left end face of the support plate.

[0003] However, the above solution has the following shortcomings: In the above patent, rotating the fine-tuning knob drives the lead screw to rotate in the groove, causing the nut seat to move on the lead screw. The movement of the nut seat drives the base to move, which in turn moves the base plate and the workpiece, thus realizing the function of adjusting the processing position. Although this method can adjust the horizontal position of the workpiece, for some workpieces, after processing the upper surface, it is also necessary to process the side surface. In this case, the operator can only process the side surface of the workpiece after processing the upper surface, remove the workpiece and re-clamp it. This is cumbersome and cannot perform clamping and processing of multiple different positions of the workpiece in one clamping. Therefore, we have introduced a multi-purpose batch processing fixture. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-purpose batch processing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

One side of the first gear meshes with a transmission mechanism. The transmission mechanism is located inside the connecting block. The end of the transmission mechanism away from the first gear is connected to a lead screw. The first gear drives the transmission mechanism to rotate, which in turn drives the lead screw to rotate the connecting gear, thus achieving the flipping of the two sets of rotating seats.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by placing several sets of workpieces to be processed between two sets of clamping plates, pushing the second square rod inward to make it engage with the corresponding square groove, and at the same time, the first square rod will also engage with the corresponding square groove. By rotating the second square rod, the two sets of positive and negative thread screws can be driven to rotate, so that several sets of workpieces are clamped by the clamping plates. When it is necessary to process the side of the workpiece, by pulling the second square rod backward, the first gear is engaged with the transmission mechanism.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-11 The present invention provides a technical solution:

[0030] Example 1:

[0031] A multi-purpose batch processing fixture includes a base 1. Two sets of rotating seats 2 are provided on the upper end of the base 1. One end of each rotating seat 2 is movably connected to the inner side of the base 1, and the other end is fixedly connected to a connecting gear 13. The end of the connecting gear 13 away from the rotating seat 2 is movably connected to the inner side of the base 1. The lower end of the connecting gear 13 meshes with a lead screw 14, which is movably connected to the inner side of the base 1. The rotation of the lead screw 14 drives the meshing connecting gear 13 to rotate, which in turn drives the rotating seats 2 to rotate. Two sets of clamping plates 3 are movably connected to the inner side of each rotating seat 2. Several sets of clamping holes 16 are provided on the opposing surfaces of the two sets of clamping plates 3 to clamp the workpiece 37. The upper end of the clamping plate 3 has several sets of through holes 36, which allow the machining tool to be positioned. Several sets of positioning rods 5 are provided between the two sets of clamping plates 3. The lower end of the positioning rod 5 is fixedly connected to the upper end of the rotating seat 2. Several sets of workpieces 37 to be processed are inserted into the upper end of the positioning rod 5. The positioning rod 5 is used to position the workpieces 37. The inner side of the rotating seat 2 is movably connected to a positive and negative thread screw 6. The two sets of threads on the outer side of the positive and negative thread screw 6 are mirrored to ensure that the two sets of clamping plates 3 can clamp the workpieces 37 when the positive and negative thread screw 6 rotates. Both sets of clamping plates 3 are screwed to the outer side of the positive and negative thread screw 6. The rotation of the positive and negative thread screw 6 drives the two sets of clamping plates 3 to clamp the workpieces 37.

[0032] A square groove 30 is provided inside the screw rod 6, and a groove 21 is provided inside the outer side of the screw rod 6. A locking mechanism is sleeved on the outer side of the groove 21. One end of the locking mechanism extends into the external environment. A first square rod 9 is slidably connected in the square groove 30 inside the right side of the screw rod 6. The left side of the first square rod 9 extends into the external environment and is fixedly sleeved with a first pressure plate 35. One end of the first square rod 9 is inserted into the square groove 30 on the left side, so that the first pressure plate 35 presses the locking mechanism. After the locking mechanism is pressed, the locking limit on the screw rod 6 is released. A connecting block 12 is fixedly connected to one side of the base 1. A second square rod 8 is slidably connected in the connecting block 12. A first gear 22 is sleeved on the outer side of the second square rod 8. The first gear 22 is slidably connected in the sliding cavity 7, which is opened in the connecting block 12. One end of the second square rod 8 extends into the external environment, and the other end also extends into the external environment and is sleeved with a second pressure plate 29.

[0033] One side of the first gear 22 meshes with the transmission mechanism, which is located within the connecting block 12. The end of the transmission mechanism away from the first gear 22 is connected to the lead screw 14. The first gear 22 drives the transmission mechanism to rotate, causing the lead screw 14 to drive the connecting gear 13 to rotate, thus achieving the rotation of the two sets of rotating seats 2. The transmission mechanism includes a transmission gear 27, which is movably connected within the connecting block 12. A pulley 28 is fixedly connected to one side of the transmission gear 27 and movably connected within the connecting block 12. The pulley 28 is connected to the connecting wheel 11 via a belt 10. The connecting wheel 11... The lead screw 14 is fixedly connected, and the connecting wheel 11 is set inside the connecting block 12. Pulling the second square rod 8 backward causes the first gear 22 connected to it to mesh with the transmission gear 27. After the first gear 22 meshes with the transmission gear 27, the second square rod 8 is rotated to drive the first gear 22 to start rotating. 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, the connecting wheel 11 will also start to rotate as the pulley 28 rotates.

[0034] Example 2:

[0035] Based on Embodiment 1, in order to prevent the two sets of clamping plates 3 from moving outward during processing, guide rods 4 are movably connected to both sides of the two sets of clamping plates 3. Both ends of the guide rods 4 are fixedly connected to the inner side of the rotating seat 2, guiding the clamping plates 3 through the guide rods 4. The locking mechanism includes a connecting ring 18, which is sleeved on the outside of the groove 21 and slides in the connecting cavity 32. Two sets of L-shaped pressure rods 17 are fixedly connected to one end of the connecting ring 18, with the end of the L-shaped pressure rod 17 away from the connecting ring 18 extending into the external environment. Several sets of limiting holes 20 are opened in one side of the groove 21. Two sets of locking blocks 19 are fixedly connected to the end of the connecting ring 18 near the limiting holes 20. The connecting ring 18 is snapped into the limiting hole 20. The end of the connecting ring 18 away from the L-shaped pressure rod 17 is fixedly connected to the first spring 31. The other end of the first spring 31 is fixedly connected to the connecting cavity 32. When the second square rod 8 moves, it will drive the second pressure plate 29 to move. When the first square rod 9 moves, it will drive the first pressure plate 35 to move. When the first pressure plate 35 and the second pressure plate 29 come into contact with the corresponding L-shaped pressure rod 17, the L-shaped pressure 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 screw 6 is in a movable state.

[0036] The first square rod 9 slides within the square groove 30 on the right side. A limiting ring 15 is sleeved on the outer side of the first square rod 9, and the limiting ring 15 slides within the guide groove 34, which is located within the square groove 30 on the right side. A second spring 33 is sleeved on the outer side of the first square rod 9. One end of the second spring 33 is fixedly connected to the guide groove 34, and the other end is fixedly connected to the limiting ring 15. The transmission mechanism includes a transmission gear 27, which is movably connected within the connecting block 12. A pulley 28 is fixedly connected to one side of the transmission gear 27 and movably connected within the connecting block 12. The pulley 28 is connected to the connecting wheel 1 via a belt 10. The connecting wheel 11 is fixedly connected to the lead screw 14. The connecting wheel 11 is set in the connecting block 12. When the side of the workpiece 37 needs to be processed, the second square rod 8 is pulled back to drive the first gear 22 connected to it to mesh with the transmission gear 27. By rotating the second square rod 8, the first gear 22 starts to rotate. The rotation of the first gear 22 drives the transmission gear 27 to start to rotate. The rotation of the transmission gear 27 drives the pulley 28 to start 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 as the pulley 28 rotates.

[0037] A U-shaped locking rod 23 is provided on one side of the first gear 22. The U-shaped locking rod 23 slides in the cavity 24, which is located inside the connecting block 12. Several sets of locking holes 26 are provided in the end of the transmission gear 27 near the U-shaped locking rod 23. The U-shaped locking rod 23 is locked in the locking holes 26. Two sets of connecting springs 25 are fixedly connected in the cavity 24. The other end of the connecting springs 25 is fixedly connected to the U-shaped locking rod 23. After the first gear 22 meshes with the transmission gear 27, the U-shaped locking rod 23 will be pushed inward. At this time, the U-shaped locking rod 23 locked in the locking hole 26 will disengage, making the transmission gear 27 movable. When it is rotated to the appropriate position, the second square rod 8 is released. Under the elastic force of the connecting spring 25, the U-shaped locking rod 23 will lock into the corresponding locking hole 26, making the transmission gear 27 unable to rotate.

[0038] Working principle: During use, several sets of workpieces 37 to be processed are inserted into the upper end of the positioning rod 5. After insertion, the second square rod 8 is pushed inward so that its insertion end is inserted into the square groove 30 on the right. When the second square rod 8 enters the square groove 30 on the right, 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, the movement of the second square rod 8 will drive the second pressure plate 29 to move. The movement of the first square rod 9 will drive the first pressure plate 35 to move. When the first pressure plate 35 and the second pressure plate 29 come into contact with the corresponding L-shaped pressure rod 17, the L-shaped pressure 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 screw 6 is in a movable state.

[0039] Rotating the second square rod 8 drives the right-side threaded screw 6 to rotate. When the right-side threaded screw 6 rotates, it drives the left-side threaded screw 6 to rotate via the first square rod 9. Since two sets of clamping plates 3 are screwed to the outside of both sets of threaded screws 6, the two sets of clamping plates 3 will move inward to clamp the workpiece 37 when the threaded screw 6 rotates. After clamping, the second square rod 8 is pulled out from 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 threaded screw 6 is limited and fixed, ensuring that the two sets of clamping plates 3 can no longer move. The outer side and the upper end of the workpiece 37 are processed through several sets of through holes 36.

[0040] When machining is required on the side of workpiece 37, pulling the second square rod 8 backward causes the first gear 22 connected to it to mesh with the transmission gear 27. After the first gear 22 meshes with the transmission gear 27, the U-shaped locking rod 23 is pushed inward, and the U-shaped locking rod 23, which is locked in the locking hole 26, disengages, making the transmission gear 27 movable. Rotating the second square rod 8 causes the first gear 22 to start rotating, which in turn causes the transmission gear 27 to start rotating, which in turn causes the pulley 28 to start rotating. Because the belt 10 and the pulley 28 are connected... Since the connecting wheel 11 is connected, when the belt pulley 28 rotates, the connecting wheel 11 will also start to rotate. At this time, the lead screw 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. When it is flipped to the appropriate position, the second square rod 8 is released. Under the elastic force of the connecting spring 25, the U-shaped locking rod 23 will lock into the corresponding locking hole 26, so that the transmission gear 27 cannot rotate. At this time, the side of the workpiece 37 can be processed. After processing, the rotating seat 2 is rotated to the horizontal position according to the above method, and the two sets of clamping plates 3 are opened to take out the processed workpiece 37.
