Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a clamping tooling for detecting annular parts. Background Technique

[0002] In the process of mechanical manufacturing, a device used to fix the processing object and let the processing object receive construction or detection is called a fixture; when a large-diameter annular part needs to be processed into a fixed-distance ring, a fixture is required to fix and position the annular part, and then tools are used to perform welding, chamfering, grinding, cutting, etc. on the annular part. When an annular part needs to be detected and fixed, a clamping tooling for detecting annular parts is required at this time.

[0003] According to a disclosed clamping tooling for annular parts (publication number: CN219945130U), the above application solves the problem that the existing clamping tooling for annular parts usually can only clamp the inner ring of the part or only the outer ring of the part, resulting in low flexibility in the application of the clamping tooling for annular parts and being not conducive to people's use.

[0004] However, in the actual use process of the above device, when the clamping plate fixes the annular part, it is difficult to fix parts with different diameters. When encountering parts with different diameters, the parts are difficult to be fixed on the tooling, reducing the application range of the tooling; in view of this, we propose a clamping tooling for detecting annular parts. Content of the Utility Model

[0005] The purpose of the utility model is to provide a clamping tooling for detecting annular parts to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A clamping tooling for detecting annular parts, including a mounting plate, the lower end of the mounting plate is fixedly connected with a limiting plate, the outer wall of the limiting plate is slidably connected with the inner wall of the base, the inner wall of the base is fixedly connected with a motor, the output end of the motor is fixedly connected with a transmission rod, the end of the transmission rod away from the motor is fixedly connected with the outer wall of the lower end of the mounting plate, and a clamping assembly is arranged inside the mounting plate. The clamping assembly includes:

[0007] A sliding rod, the sliding rod penetrates and is slidably connected to the outer wall of the mounting plate, one end of the sliding rod close to the outer wall of the mounting plate is fixedly connected with a runner, and the end of the sliding rod away from the runner is fixedly connected with a bidirectional lead screw, and a rotating seat is rotatably connected to the outer wall of the bidirectional lead screw;

[0008] A sliding seat, the sliding seat is threadedly connected to the arc-shaped outer surface of the bidirectional lead screw, a stop block is fixedly connected to the outer wall of the sliding seat, a limiting block is fixedly connected to the lower outer wall of the rotating seat, and a self-locking spring rod is fixedly connected to the lower end of the limiting block;

[0009] A rotating shaft is fixedly connected to the lower outer wall of the output end of the self-locking spring rod. A connecting plate is rotatably connected to the rotating shaft away from the self-locking spring rod. One end of the connecting plate away from the rotating shaft is rotatably connected to a cross plate, and a rotating shaft penetrates through and is rotatably connected to the center of the cross plate.

[0010] Preferably, the self-locking spring rod is fixedly connected to the inner wall of the mounting disk. The rotating seat is slidably connected to the inner wall of the mounting disk through a limiting block, so that the rotating seat can move on the inner wall of the mounting disk, thereby changing the position of the blocking block.

[0011] Preferably, the lower end of the rotating shaft is fixedly connected to the inner wall of the mounting disk, so that the cross plate can rotate around the rotating shaft. After the cross plate rotates, the connecting plate at the end of the cross plate can be pulled to drive the self-locking spring rod to expand and contract by the same distance. Rings are fixedly connected to both ends of the bidirectional lead screw. A ring groove matching the ring is formed in the inner wall of the rotating seat, and the ring is slidably connected to the inner wall of the ring groove. Pulling the rotating wheel can make the sliding rod drive the rotating seat to move.

[0012] Preferably, the number of the clamping assemblies is set to four groups. The four groups of clamping assemblies are distributed on the outer wall of the mounting disk in a circumferential array, and the four groups of connecting plates are all rotatably connected to the ends of the cross plate, so that the annular part can be more firmly fixed on the mounting disk. When pulling one rotating wheel, the cross plate rotates, so that the cross plate pulls other self-locking spring rods to expand and contract, and the self-locking spring rods can expand and contract by the same distance.

[0013] Preferably, an arc-shaped block is fixedly connected to the outer wall of the blocking block, so that the blocking block can better contact the annular part. A sliding groove is formed in the outer wall of the mounting disk. The sliding seat is fixedly connected to the blocking block through a sliding block, and the sliding block is slidably connected to the inner wall of the sliding groove, so that the movement of the sliding seat inside the mounting disk can drive the blocking block outside the mounting disk to move to clamp the annular part.

[0014] Preferably, a limiting groove matching the size of the limiting plate is formed in the outer wall of the base. The limiting plate is slidably connected to the inner wall of the limiting groove. The motor drives the mounting disk to rotate through a transmission rod, so that the annular part is easier to be detected.

[0015] Compared with the prior art, the utility model provides a detection and clamping tooling for annular parts, which has the following beneficial effects:

[0016] 1. For this annular part detection and clamping tooling, by pushing the rotating wheel, the rotating wheel drives the rotating seat to move to a suitable position through the sliding rod, enabling the stopper to fix annular parts with different diameters. Place the annular part on the mounting plate so that the edge of the annular part is located between the stoppers. Then rotate the rotating wheel, which drives the bidirectional lead screw to rotate, so that the stoppers at both ends of the bidirectional lead screw can clamp annular parts with different thicknesses, expanding the applicable range of the tooling.

[0017] 2. For this annular part detection and clamping tooling, when the rotating seat moves to drive the self-locking spring rod to expand and contract, the connecting plate pushes the cross plate to rotate around the rotating shaft. The rotation of the cross plate causes the connecting plates at the four ends of the cross plate to simultaneously pull the self-locking spring rod to expand and contract, and drives the rotating seat to move. Moreover, the moving distances of the rotating seat are consistent, enabling the annular part to be fixed at the center of the mounting plate and making the annular part easier to be detected.

[0024] As Figures 1 - 5As shown in the figure, the present utility model provides a technical solution: a clamping tool for detecting annular parts, which includes a mounting plate 1. A limiting plate 2 is fixedly connected to the lower end of the mounting plate 1. The outer wall of the limiting plate 2 is slidably connected to the inner wall of the base 3. A motor 4 is fixedly connected to the inner wall of the base 3. The output end of the motor 4 is fixedly connected to a transmission rod 5. The end of the transmission rod 5 away from the motor 4 is fixedly connected to the outer wall of the lower end of the mounting plate 1. A clamping assembly 6 is arranged inside the mounting plate 1. The clamping assembly 6 includes a sliding rod 61, a rotating wheel 62, a bidirectional lead screw 63, a rotating seat 64, a sliding seat 65, a stopper 66, a limiting block 67, a self-locking spring rod 68, a rotating shaft 69, a connecting plate 610, a cross plate 611, and a rotating shaft 612.

[0025] In an embodiment of the present utility model, the sliding rod 61 penetrates and is slidably connected to the outer wall of the mounting plate 1. A rotating wheel 62 is fixedly connected to one end of the sliding rod 61 close to the outer wall of the mounting plate 1. A bidirectional lead screw 63 is fixedly connected to the end of the sliding rod 61 away from the rotating wheel 62. The outer wall of the bidirectional lead screw 63 is rotatably connected to a rotating seat 64.

[0026] In an embodiment of the present utility model, the sliding seat 65 is threadedly connected to the arc-shaped outer surface of the bidirectional lead screw 63. A stopper 66 is fixedly connected to the outer wall of the sliding seat 65. A limiting block 67 is fixedly connected to the lower outer wall of the rotating seat 64. A self-locking spring rod 68 is fixedly connected to the lower end of the limiting block 67.

[0027] In an embodiment of the present utility model, a rotating shaft 69 is fixedly connected to the lower outer wall of the output end of the self-locking spring rod 68. The rotating shaft 69 is rotatably connected to a connecting plate 610 away from the self-locking spring rod 68. One end of the connecting plate 610 away from the rotating shaft 69 is rotatably connected to a cross plate 611. The center of the cross plate 611 penetrates and is rotatably connected to a rotating shaft 612.

[0028] In addition, the self-locking spring rod 68 is fixedly connected to the inner wall of the mounting plate 1. The rotating seat 64 is slidably connected to the inner wall of the mounting plate 1 through the limiting block 67, so that the rotating seat 64 can move on the inner wall of the mounting plate 1, thereby changing the position of the stopper 66, and enabling the stopper 66 to fix annular parts with different diameters.

[0029] In an embodiment of the present utility model, the lower end of the rotating shaft 612 is fixedly connected to the inner wall of the mounting plate 1, so that the cross plate 611 can rotate around the rotating shaft 612. Thus, after the cross plate 611 rotates, it can pull the connecting plate 610 at the end of the cross plate 611 to drive the self-locking spring rod 68 to stretch and contract the same distance. Rings are fixedly connected to both ends of the bidirectional lead screw 63. A ring groove matching the rings is provided on the inner wall of the rotating seat 64. The rings are slidably connected to the inner wall of the ring groove. Pulling the rotating wheel 62 can make the sliding rod 61 drive the rotating seat 64 to move, and when the sliding rod 61 can drive the rotating seat 64 to move, it does not affect the rotation of the bidirectional lead screw 63.

[0030] In an embodiment of the present utility model, the number of clamping assemblies 6 is set to four groups. The four groups of clamping assemblies 6 are distributed on the outer wall of the mounting plate 1 in a circumferential array, and the four groups of connecting plates 610 are all rotatably connected to the ends of the cross plate 611, so that the annular part can be more firmly fixed on the mounting plate 1. When pulling one set of rotating wheels 62, the cross plate 611 rotates, thereby causing the cross plate 611 to pull other self-locking spring rods 68 to expand and contract, enabling the self-locking spring rods 68 to expand and contract by the same distance, so that the stopper 66 can install the annular part at the center of the mounting plate 1.

[0031] In an embodiment of the present utility model, an arc block is fixedly connected to the outer wall of the stopper 66, so that the stopper 66 can better contact the annular part. A sliding groove is provided on the outer wall of the mounting plate 1. The sliding seat 65 is fixedly connected to the stopper 66 through a slider, and the slider is slidably connected to the inner wall of the sliding groove, so that the movement of the sliding seat 65 inside the mounting plate 1 can drive the stopper 66 outside the mounting plate 1 to move to clamp the annular part.

[0032] In an embodiment of the present utility model, a limiting groove matching the size of the limiting plate 2 is provided on the outer wall of the base 3. The limiting plate 2 is slidably connected to the inner wall of the limiting groove. The motor 4 drives the mounting plate 1 to rotate through the transmission rod 5, making it easier to detect the annular part. At this time, the limiting plate 2 slides in the limiting groove, making the rotation of the mounting plate 1 more stable.

[0033] In the present utility model, during use, push the rotating wheel 62, so that the rotating wheel 62 drives the rotating seat 64 to move to a suitable position through the sliding rod 61, enabling the stopper 66 to fix annular parts with different diameters. At this time, the self-locking spring rod 68 is driven by the rotating seat 64 to expand and contract. At the same time, the self-locking spring rod 68 has a self-locking structure, which can fix the position of the rotating seat 64 after movement. Then place the annular part on the mounting plate 1, so that the edge of the annular part is located between the stoppers 66. Then rotate the rotating wheel 62, so that the rotating wheel 62 drives the bidirectional lead screw 63 to rotate, thereby enabling the stoppers 66 at both ends of the bidirectional lead screw 63 to clamp annular parts with different thicknesses. When the rotating seat 64 moves to drive the self-locking spring rod 68 to expand and contract, the connecting plate 610 moves accordingly, thereby pushing the cross plate 611 to rotate around the rotating shaft 612. When the cross plate 611 rotates, the connecting plates 610 at the four ends of the cross plate 611 simultaneously pull the self-locking spring rod 68 to expand and contract, and drive the rotating seat 64 to move, and the distances of the movement of the rotating seat 64 are the same, enabling the annular part to be fixed at the center of the mounting plate 1. After the annular part is fixed, the motor 4 can drive the mounting plate 1 to rotate through the transmission rod 5, thereby rotating the annular part on the mounting plate 1, making it more convenient to detect the annular part.

[0034] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
