When used for clamping internal gear rings, it is inconvenient and inefficient. It cannot be flipped and can only be processed on one side. When the other side needs to be processed, it needs to be clamped again, which affects the processing efficiency of internal gear rings and has limitations in use. In view of this, a clamping device for machining internal gear rings is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for machining internal gear rings, so as to solve the problems mentioned in the background art that the existing clamping devices are cumbersome and inconvenient to operate and cannot be flipped for machining, resulting in low machining efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for machining internal gear rings, comprising a base,

[0006] Two through slots, symmetrically arranged, are formed through each other on the top surface of the base;

[0007] A moving mechanism is disposed on the inner bottom surface of the base;

[0008] A supporting mechanism, which is connected to the moving mechanism;

[0009] A lifting mechanism is disposed on the top surface of the base and is connected to the supporting mechanism;

[0010] A rotating mechanism, which is connected to the lifting mechanism.

[0011] The above technical solution facilitates the rapid clamping and flipping of the internal gear ring, thereby improving processing efficiency.

[0012] As a preferred embodiment of this utility model, the moving mechanism includes:

[0013] The first motor is fixedly installed on the right side of the inner bottom surface of the base;

[0014] A bidirectional lead screw, the right end of which is keyed to the shaft end of the first motor, and the left end of which is connected to a bearing on the left inner wall of the base;

[0015] The bottom surfaces of two symmetrically arranged slide rods are slidably connected to the inner bottom surface of the base, and the bidirectional lead screw passes through the slide rod and is threadedly connected to the slide rod, and the slide rod passes through the through groove.

[0016] By adopting the above technical solution, it is easy to make the two slide rods move in opposite directions by rotating the bidirectional lead screw.

[0017] As a preferred embodiment of this utility model, the supporting mechanism includes:

[0018] An upright plate is fixedly installed on the top surface of the slide rod;

[0019] The mounting shaft has its outer end connected to a bearing on the inner side of the vertical plate.

[0020] A fixed base is fixedly installed on the inner end of the mounting shaft.

[0021] By adopting the above technical solution, it is possible to support the internal gear ring when the slide rod drives the mounting shaft and the fixed seat to move.

[0022] As a preferred embodiment of this utility model, the inner side of the fixing base is arc-shaped, and the inner side of the fixing base is provided with a rubber anti-slip pad.

[0023] The above technical solution facilitates the improvement of the stability of the internal gear ring clamping and fixing, while also providing a protective effect.

[0024] As a preferred embodiment of this utility model, the lifting mechanism includes:

[0025] The second motor is fixedly installed on the top surface of the base;

[0026] An adjusting lead screw, the bottom end of which is keyed to the shaft end of the second motor;

[0027] A connecting plate is sleeved on the outside of the adjusting screw, and the adjusting screw is threadedly connected to the connecting plate;

[0028] The slide is slidably connected to the inner side of the upright plate, and the slide is hollow with an open inner end face, and the connecting plate is slidably connected to the inner wall surface of the slide.

[0029] By adopting the above technical solution, it is easy to move the connecting plate and the slide by adjusting the rotation of the lead screw.

[0031] A rack, which is fixedly mounted on the top surface of the slide;

[0032] The gear is fixedly mounted on the mounting shaft, and the rack is meshed with the gear.

[0033] By adopting the above technical solution, when the slide moves and drives the rack to move, the gear drives the mounting shaft and the fixed seat to rotate, thereby realizing the flipping of the fixed internal gear ring.

[0034] Compared with the prior art, the beneficial effects of this utility model are: the holding device for internal gear ring processing can quickly hold and fix the internal gear ring, and can flip the internal gear ring to ensure rapid double-sided processing of the internal gear ring. It is convenient and flexible to operate, can effectively improve the processing effect of the internal gear ring, and is highly practical.

[0035] 1. The start of the first motor causes the bidirectional lead screw to rotate, which causes the two slide bars to move towards each other, thereby causing the vertical plate to move the mounting shaft and the fixed seat inward, which can then hold the internal gear ring to ensure that the internal gear ring can be processed. At the same time, the rubber anti-slip pad can improve the stability of the holding of the internal gear ring and play a protective role.

[0036] 2. The sliding connection between the connecting plate and the slide block ensures the effective movement of the upright plate. At the same time, when the second motor is started and the adjusting screw is rotated, the connecting plate can drive the slide block to move up and down. When the slide block moves and drives the rack to move, it will drive the mounting shaft and the fixed seat to rotate through the gear, which can realize the flipping of the internal gear ring, realize double-sided processing of the internal gear ring, and improve the processing efficiency of the internal gear ring.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figure 1-4 The present invention provides a holding device for machining internal gear rings, comprising a base 1 and two symmetrically arranged through slots 2 that are opened through the top surface of the base 1.

[0044] The first motor 3 is fixedly installed on the right side of the inner bottom surface of the base 1. The right end of the bidirectional lead screw 4 is keyed to the shaft end of the first motor 3, and the left end of the bidirectional lead screw 4 is connected to the bearing on the left inner wall surface of the base 1. The bottom surfaces of the two symmetrically arranged slide rods 5 are slidably connected to the inner bottom surface of the base 1. The bidirectional lead screw 4 passes through the slide rod 5 and is threadedly connected to the slide rod 5. The slide rod 5 passes through the through groove 2.

[0045] The upright plate 6 is fixedly installed on the top surface of the slide rod 5. The outer end of the mounting shaft 7 is connected to the inner side bearing of the upright plate 6. The fixing seat 8 is fixedly installed on the inner end of the mounting shaft 7. The inner side of the fixing seat 8 is arc-shaped and is provided with a rubber anti-slip pad 9.

[0046] The second motor 10 is fixedly installed on the top surface of the base 1. The bottom end of the adjusting screw 11 is keyed to the shaft end of the second motor 10. The connecting plate 12 is sleeved on the outside of the adjusting screw 11, and the adjusting screw 11 is threadedly connected to the connecting plate 12. The slide block 13 is slidably connected to the inner side of the upright plate 6. The slide block 13 is hollow with an open inner end face, and the connecting plate 12 is slidably connected to the inner wall surface of the slide block 13.

[0047] The rack 14 is fixedly installed on the top surface of the slide 13, and the gear 15 is fixedly mounted on the mounting shaft 7, with the rack 14 and gear 15 meshing together.

[0048] Working principle: When in use, the first motor 3 is started to rotate the bidirectional lead screw 4, which causes the two slide rods 5 threaded to the bidirectional lead screw 4 to move in opposite directions. This causes the slide rods 5 to drive the vertical plate 6, the mounting shaft 7 and the fixed seat 8 to move inward synchronously. The two fixed seats 8 can then clamp the internal gear ring. At the same time, the rubber anti-slip pad 9 improves the stability of the clamping of the internal gear ring, ensuring that the internal gear ring can be effectively processed.

[0049] When it is necessary to flip the internal gear ring, the second motor 10 is started to rotate the adjusting screw 11, which causes the connecting plate 12, which is threaded to the adjusting screw 11, to move the slide 13 upward. This causes the slide 13 to move the rack 14 upward synchronously, which in turn causes the gear 15, which meshes with the rack 14, to rotate the mounting shaft 7 and the fixed seat 8. This allows the internal gear ring to be flipped, enabling double-sided processing of the internal gear ring and improving the processing efficiency. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
