Description

Technical Field

[0001] This utility model belongs to the field of tapping technology, and specifically relates to a positioning fixture for a tapping machine. Background Technology

[0002] A tapping machine is a machining device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges, using either through holes or blind holes of different specifications. Tapping machines are also called thread tapping machines, automatic tapping machines, etc. With the continuous advancement of industrial technology, the types and models of tapping machines have become increasingly diverse to meet the needs of different industries and fields.

[0003] In machining, tapping is a crucial process for forming internal threads. Tapping machine positioning fixtures are key auxiliary equipment to ensure tapping accuracy and efficiency. Currently, once the positioning fixture fixes the workpiece in place, its tapping position cannot be changed. If tapping is required at different positions on the same workpiece during machining, or if the tapping position needs to be adjusted after changing to workpieces of different specifications, operators often need to disassemble and reassemble the workpiece and perform tedious positioning and calibration work again. This not only consumes a lot of time and manpower, but also easily damages the workpiece due to repeated disassembly and reassembly, affecting the machining quality and failing to meet the high-efficiency and flexible production requirements of modern machining.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a positioning fixture for a tapping machine, including a base, a movable component mounted on the base, a rotating component mounted on the movable component, a placement structure mounted on the rotating component, and a clamping component mounted on the placement structure.

[0006] The clamping assembly is used to fix the workpiece to the placement structure, the rotating assembly is used to drive the placement structure to rotate, and the moving assembly is used to drive the placement structure to move, so that the workpiece placed on the placement structure can flexibly change its tapping position.

[0007] The moving component includes two positioning rails. One positioning rail contains a positioning rod, and the other positioning rail contains a screw. A first driving device is installed at one end of the positioning rail containing the screw, and the driving end of the first driving device is connected to one end of the screw.

[0008] The rotating assembly includes a positioning plate with two positioning blocks symmetrically mounted on its bottom surface. Both positioning blocks are slidably engaged with the positioning rail, with one positioning block sliding through the positioning rod and the other positioning block sliding through and threadedly connected to the screw rod.

[0009] The placement structure includes a placement seat, a rotating seat coaxially mounted on the bottom of the placement seat, the rotating seat rotatably mounted on the positioning plate and coaxially arranged, a worm gear coaxially arranged on the rotating seat, the rotating assembly also includes a rotating rod, a worm gear is mounted around the rotating rod, the worm gear meshes with the worm gear, a second driving device is provided at one end of the rotating rod, and one side of the second driving device is mounted on the bottom surface of the positioning plate.

[0010] The upper surface of the placement seat is symmetrically provided with guide grooves. The clamping assembly includes a drive plate, which is installed in the inner cavity of the placement seat. The middle part of the drive plate is coaxial with the placement seat. A third drive device is installed in the inner cavity of the placement seat. The drive end of the third drive device is connected to the middle part of the drive plate. Connecting plates are rotatably installed at both ends of the drive plate. The clamping assembly also includes two clamping plates. The lower end of each clamping plate is slidably installed in a guide groove, and the lower end of each clamping plate is rotatably installed on the end of a connecting plate that is farther away from the drive plate.

[0011] The base is also equipped with a lifting device, and a mounting plate is installed on the upper end of the lifting device. A tapping device is installed on the mounting plate.

[0012] Both clamping plates have a protective layer on opposite sides.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model achieves flexible adjustment of the tapping position through the coordinated operation of the screw and the worm gear. When the horizontal position changes, the screw can drive the placement seat to move precisely. For non-horizontal position adjustments, the worm gear drives the worm wheel to rotate the rotating seat and the placement seat, turning the target tapping position to a horizontally corresponding position. Then, the screw moves to complete the positioning, thus eliminating the cumbersome steps of disassembling and reinstalling the workpiece in traditional processes, significantly improving production efficiency, and effectively enhancing the flexibility and efficiency of machining.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] Please see Figure 1 , Figure 2 As shown:

[0024] This embodiment provides a tapping machine positioning fixture, including a base 1, a moving component 2 mounted on the base 1, a rotating component 3 mounted on the moving component 2, a placement structure 4 mounted on the rotating component 3, and a clamping component 5 mounted on the placement structure 4.

[0025] The clamping assembly 5 is used to fix the workpiece to the placement structure 4, the rotating assembly 3 is used to drive the placement structure 4 to rotate, and the moving assembly 2 is used to drive the placement structure 4 to move, so that the workpiece placed on the placement structure 4 can flexibly change its tapping position.

[0026] In practical use, the operator places the workpiece on the placement structure 4 and clamps it in place using the clamping assembly 5. This clamping assembly 5 can hold workpieces of different sizes, ensuring stability during subsequent processing. After fixing, tapping is performed. When the tapping position needs to be changed, if the tapping position is horizontally aligned with the initial tapping position, simply move the moving assembly 2 to align it with the tapping part for tapping. If the tapping position to be changed is not horizontally aligned with the initial position, first rotate the workpiece using the rotating assembly 3 to make the tapping position horizontally aligned with the initial position. Then, move the moving assembly 2 to align the tapping position with the tapping part for tapping. This allows the device to flexibly change the tapping position when the workpiece is fixed, eliminating the need for tedious disassembly and reassembly, improving work efficiency, and meeting the high-efficiency and flexible production requirements of modern machining.

[0027] like Figures 1-3 As shown, the moving component 2 includes two positioning rails 6. One positioning rail 6 has a positioning rod 7 installed inside, and the other positioning rail 6 has a screw 8 installed inside. A first driving device 9 is installed on one end of the positioning rail 6 with the screw 8. The first driving device 9 includes, but is not limited to, a motor. The driving end of the first driving device 9 is connected to one end of the screw 8. The rotating component 3 includes a positioning plate 10. Two positioning blocks 11 are symmetrically installed on the bottom surface of the positioning plate 10. Both positioning blocks 11 are slidably engaged with the positioning rail 6. One positioning block 11 slides through the positioning rod 7, and the other positioning block 11 slides through and is threadedly connected to the screw 8. The first driving device 9 drives the screw 8 to rotate, so that the positioning blocks 11 move through the rotation of the screw 8. The other positioning block 11 is also slidably engaged with the positioning rod 7, so that the positioning blocks 11 drive the positioning plate 10 to move within the positioning rail 6, thereby realizing the horizontal displacement of the rotating component 3 and the placement structure 4.

[0028] like Figure 2 , Figure 3 , Figure 4As shown, the placement structure 4 includes a placement seat 12, which is hollow inside. A rotating seat 13 is coaxially mounted on the bottom of the placement seat 12. The rotating seat 13 is rotatably mounted on the positioning plate 10 and is coaxially arranged. A worm gear 14 is coaxially arranged on the rotating seat 13. The rotating assembly 3 also includes a rotating rod 15, around which a worm gear 16 is mounted. The worm gear 16 meshes with the worm gear 14. A second driving device 17 is provided at one end of the rotating rod 15. The second driving device 17 includes, but is not limited to, a motor. The driving end of the second driving device 17 is connected to the rotating rod 15. Furthermore, the second drive device 17 is mounted on the bottom surface of the positioning plate 10. When it is necessary to rotate the workpiece to change its tapping position, the second drive device 17 can drive the worm gear 16 on the rotating rod 15 to rotate, so that the worm wheel 14 drives the rotating seat 13 to rotate, thereby the rotating seat 13 drives the placement seat 12 to rotate, thereby realizing the angle adjustment of the workpiece placed on the placement seat 12. In this way, with the combination of the screw 8 driving the positioning plate 10 to move and the worm gear 16 driving the placement seat 12 to rotate, the tapping position can be flexibly changed without the need to disassemble and reinstall the workpiece.

[0029] like Figure 2 , Figure 5 As shown, guide grooves 18 are symmetrically arranged on the upper surface of the placement seat 12. The clamping assembly 5 includes a drive plate 19, which is installed in the inner cavity of the placement seat 12. The middle part of the drive plate 19 is coaxially opposite to the placement seat 12. A third drive device 20 is installed in the inner cavity of the placement seat 12. The third drive device 20 includes, but is not limited to, a motor. The drive end of the third drive device 20 is connected to the middle part of the drive plate 19. Connecting plates 21 are rotatably installed at both ends of the drive plate 19. The clamping assembly 5 also includes clamping plates 22. There are two clamping plates 22. The lower end of one clamping plate 22 is slidably installed in a guide groove 18, and the lower end of one clamping plate 22 is rotatably installed on the end of a connecting plate 21 that is farther away from the drive plate 19. After the workpiece is placed on the surface of the placement seat 12, the third drive device 20 can drive the drive plate 19 to rotate, thereby driving the connecting plate 21 to move. This causes the two clamping plates 22 to approach each other through the guide grooves 18, clamping the workpiece to the upper surface of the placement seat 12 and fixing the position of the workpiece.

[0030] Each of the two clamping plates 22 has a protective layer 27 on one side of its opposite side. The protective layer 27 is made of materials including but not limited to sponge, rubber, and silicone. It can prevent the clamping plates 22 from directly contacting the workpiece, avoid wear, and at the same time improve friction and further strengthen the fixing ability.

[0031] like Figure 1 , Figure 4As shown, a lifting device 23 is also installed on the base 1. A mounting plate 24 is installed on the upper end of the lifting device 23. A tapping device 25 is installed on the mounting plate 24. By driving the lifting device 23, the tapping device 25 on the mounting plate 24 is moved downward to perform tapping operations on the workpiece on the placement seat 12.

[0032] The working principle of the tapping machine positioning fixture provided by this utility model is as follows: The workpiece is placed on the upper surface of the placement seat 12. The driving plate 19 drives the connecting plate 21 to move, so that the clamping plates 22 on both sides slide relative to each other along the guide groove 18, clamping the workpiece onto the placement seat 12. The tapping equipment 25 then performs tapping operations on the workpiece. When the tapping position of the workpiece is required, if the tapping position is horizontally opposite to the initial tapping position, the screw 8 drives the positioning block 11 to move, so that the placement seat 12 follows the horizontal displacement, thereby changing the tapping position of the workpiece. When the tapping position needs to be changed... When the workpiece is not horizontally aligned with its initial position, the worm gear 16 drives the worm wheel 14 to rotate, which in turn drives the rotating seat 13 and the placement seat 12 to rotate. This moves the tapping position to be horizontally aligned with the initial tapping position. Then, the screw 8 drives the placement seat 12 to move horizontally, moving the tapping position to be aligned with the tapping part of the tapping device 25. This allows the device to flexibly change the tapping position when the workpiece is in a fixed state, eliminating the need for a series of tedious disassembly and reassembly operations, improving work efficiency, and meeting the high-efficiency and flexible production requirements of modern machining.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
