Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a clamping fixture for annular metal parts. Background Technology

[0002] The outer and end faces of ring-shaped metal parts are mostly appearance surfaces, while the inner surfaces are mostly functional surfaces that match other parts. When processing such workpieces, in order to ensure product quality, it is necessary to ensure that the outer surface is free of scratches and other defects. Therefore, in production, the clamping fixture for ring-shaped parts generally adopts an internal support structure. Through the reciprocating motion of the internal support rod, the internal support block moves radially to clamp the workpiece.

[0003] For example, a ring-shaped metal clamping fixture disclosed in Chinese patent literature (publication number: CN214686128U) can convert the rotational motion of the drive device into the linear motion of the top plate inside the workpiece through the gear and rack transmission mechanism, which greatly reduces the axial dimension of the fixture and saves the space occupied by the fixture; by applying arc-shaped support plates and buffer pads on the top plate, damage to the inner wall of the workpiece by the fixture can be avoided or reduced.

[0004] However, the two sets of support plates are not on the same axis when providing support, and the single set of two support plates makes the stability of fixing the ring-shaped metal part poor. Furthermore, when processing the ring-shaped metal part, it is necessary to frequently disassemble the ring-shaped metal part and rotate it to the appropriate position before fixing it, depending on the adjustment of the processing position. The whole process is quite cumbersome and greatly reduces the processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, the two sets of support plates are not on the same axis when providing support, and the single set of two support plates results in poor stability when fixing the annular metal part. Furthermore, the annular metal part needs to be frequently disassembled and rotated to a suitable position before being fixed, which greatly reduces processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A jig for clamping annular metal parts includes a processing table. An inner support mechanism is provided above the processing table. The inner support mechanism includes a mounting housing, an annular baffle, a rotating disk, a movable slide rod, a drive rod, an arc-shaped support block, and a first worm gear.

[0008] A rotation adjustment mechanism is provided above the processing table. The rotation adjustment mechanism includes a support plate, a rotating rod, a second worm gear, a second servo motor, and a second worm. The rotation adjustment mechanism enables the fixed annular metal part to rotate.

[0009] Preferably, the inner wall of the annular baffle is fixedly sleeved with the outer side of the mounting housing, the outer side of the drive rod is rotatably connected to one side of the inner wall of the mounting housing through a bearing, and one end of the drive rod is fixedly sleeved with the inner wall of the first worm gear.

[0010] Preferably, the other end of the drive rod is fixedly connected to one side of the rotating disk, the outer side of the mounting housing is provided with a storage groove distributed in a ring array, one side of the rotating disk is provided with an inclined groove distributed in a ring array, and the outer side of the movable slide rod is slidably inserted into the inner wall of the inclined groove.

[0011] Preferably, one inner wall of the mounting housing has guide grooves arranged in a ring array, a guide slider is slidably connected to the inner wall of the guide groove, one side of the guide slider is fixedly connected to one end of the movable slide rod, the other end of the movable slide rod is fixedly connected to one side of the arc-shaped support block, and a mounting bracket is fixedly connected to one side of the mounting housing.

[0012] Preferably, a first servo motor is fixedly mounted on the inner bottom wall of the mounting bracket, and the output shaft of the first servo motor is fixedly connected to a first worm gear via a coupling, with the outer surface of the first worm gear meshing with the tooth surface of the first worm wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the combined use of the internal support mechanism and the rotation adjustment mechanism enables automated center positioning and support of the internal ring-shaped metal part, improving stability during processing.

[0028] Example

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a jig for clamping annular metal parts, including a processing table 1, an inner support mechanism is provided above the processing table 1, and the inner support mechanism includes a mounting shell 2, an annular baffle 21, a rotating disk 22, a movable slide bar 23, a drive rod 24, an arc-shaped support block 25 and a first worm gear 26. The inner support mechanism can realize the center positioning and support fixation of the annular metal parts inside.

[0030] A rotation adjustment mechanism is provided above the processing table 1. The rotation adjustment mechanism includes a support plate 3, a rotating rod 31, a second worm gear 32, a second servo motor 33, and a second worm 34. The rotation adjustment mechanism drives the fixed annular metal part to rotate.

[0031] By automating and centering the internal structure of the ring-shaped metal part and providing support and fixation, the stability during processing is improved. Furthermore, by rotating the fixed ring-shaped metal part, the need for frequent disassembly and reassembly to adjust its direction during processing is avoided, greatly improving processing efficiency.

[0032] The inner wall of the annular baffle 21 is fixedly sleeved with the outer side of the mounting housing 2. The annular baffle 21 serves to block the end of the annular metal part and prevent it from falling off when it is fixed by the inner support.

[0033] The drive rod 24 is rotatably connected to the inner wall of one side of the mounting housing 2 via a bearing. One end of the drive rod 24 is fixedly sleeved with the inner wall of the first worm gear 26. The rotation of the first worm gear 26 drives the drive rod 24 to rotate. The rotation of the drive rod 24 is stably achieved through the cooperation between the bearing and the mounting housing 2.

[0034] The other end of the drive rod 24 is fixedly connected to one side of the rotating disk 22. The rotation of the drive rod 24 drives the rotating disk 22 to rotate. The outer side of the mounting housing 2 is provided with a storage groove 27 arranged in a ring array. The side of the rotating disk 22 is provided with a sloping groove 28 arranged in a ring array. The outer side of the movable slide rod 23 is slidably inserted into the inner wall of the sloping groove 28. The rotation of the rotating disk 22, through the cooperation of the sloping groove 28, drives the movable slide rod 23 to squeeze and slide.

[0035] The inner wall of the housing 2 is provided with guide grooves 29 arranged in a ring array. A guide slider 210 is slidably connected to the inner wall of the guide groove 29. One side of the guide slider 210 is fixedly connected to one end of the movable slider 23. The guide groove 29 restricts and guides the movement of the guide slider 210, so that it moves in a specified direction, thereby cooperating with the movement of the movable slider 23 to guide and limit the movement.

[0036] The other end of the movable slide rod 23 is fixedly connected to one side of the arc surface support block 25. The movement of the movable slide rod 23 drives the arc surface support block 25 to move and extend. Multiple arc surface support blocks 25 support and fix the inside of the annular metal part. Multiple sets of arc surface support blocks 25 can be set according to the usage requirements. The outer arc surface of the arc surface support block 25 can be equipped with anti-slip rubber pads to improve the stability when supporting the inside of the annular metal part. A mounting bracket 211 is fixedly connected to one side of the mounting housing 2.

[0037] The first servo motor 212 is fixedly installed on the inner bottom wall of the mounting bracket 211. The output shaft of the first servo motor 212 is fixedly connected to the first worm 213 through a coupling. The outer surface of the first worm 213 meshes with the tooth surface of the first worm wheel 26. The first servo motor 212 serves as a stable drive source, driving the first worm 213 to rotate stably, thereby driving the meshing first worm wheel 26 to rotate.

[0038] The lower end of the support plate 3 is fixedly connected to the upper end of the processing table 1. The outer side of the rotating rod 31 is rotatably connected to the inner wall of the support plate 3 through a bearing. The inner wall of the second worm gear 32 is fixedly sleeved with one end of the rotating rod 31. The rotation of the second worm gear 32 drives the rotating rod 31 to rotate, and the rotating rod 31 rotates stably inside the support plate 3 through the cooperation of the bearing.

[0039] The other end of the rotating rod 31 is fixedly connected to one side of the mounting bracket 211, and one side of the second servo motor 33 is fixedly installed on one side of the support plate 3. The rotation of the rotating rod 31 drives the fixed ring metal part to rotate and adjust through the mounting bracket 211, thereby meeting the processing requirements of different positions.

[0040] The output shaft of the second servo motor 33 is fixedly connected to the lower end of the second worm 34 via a coupling. The outer surface of the second worm 34 meshes with the tooth surface of the second worm wheel 32. The second servo motor 33 serves as a stable drive source, driving the second worm 34 to rotate, which in turn drives the meshing second worm wheel 32 to rotate. Furthermore, the self-locking characteristics of the second worm 34 and the second worm wheel 32 ensure the stability of the annular metal part after adjustment, thereby ensuring the processing quality.

[0041] The working process of this utility model:

[0042] Step 1: Insert the annular metal part into the outside of the mounting housing 2 and make contact with the annular baffle 21. Start the first servo motor 212 to drive the first worm gear 213 to rotate. The rotation of the first worm gear 213 drives the drive rod 24 and the rotating disk 22 to rotate through the meshing first worm wheel 26. The rotation of the rotating disk 22 drives the moving slide rod 23 to move through the inclined groove 28. And through the limit of the guide slide groove 29 and the guide slider 210, the moving slide rod 23 moves along the specified direction. Then, the moving slide rod 23 drives the arc surface support block 25 to pass through the storage groove 27 and simultaneously provides internal support and fixation for the annular metal part.

[0043] Step two: According to the processing orientation requirements, start the second servo motor 33 to drive the second worm gear 34 to rotate. The rotation of the second worm gear 34 drives the rotating rod 31 to rotate through the meshing second worm wheel 32. The rotation of the rotating rod 31 drives the fixed annular metal part to rotate and adjust through the mounting bracket 211 and the mounting housing 2, thereby meeting the processing requirements and improving processing efficiency.

[0044] 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.
