Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to an auxiliary structure for calibrating the concentricity of a wire drawing machine shaft assembly. Background Technology

[0002] In the field of mechanical manufacturing, shaft components are key parts, and the accuracy of their concentricity plays a decisive role in the overall performance of the equipment. In the wire drawing process, the concentricity of the shaft components is directly related to the quality and efficiency of wire drawing. If the concentricity of the shaft components is poor, it will cause uneven stress on the wire during the wire drawing process, resulting in problems such as inconsistent thickness and rough surface. In severe cases, it may even lead to wire breakage, which greatly increases the scrap rate and increases production costs.

[0003] The existing patent publication number CN221147577U describes a shaft assembly concentricity calibration device. Through the cooperation between a second motor, a C-shaped plate, a clamping plate, bolts, and a fixing column, the shaft assembly concentricity calibration device can calibrate shafts of different specifications during use, thereby improving the calibration efficiency of the shaft assembly concentricity calibration device.

[0004] Although the above solution states that the shaft assembly can be fixed by using the clamping plate in conjunction with other components, the placement arc of the clamping plate is fixed. This means that only a shaft assembly that matches the arc of the clamping plate can be stably clamped. When placing other shaft assemblies of different sizes, the clamping plate in the above solution is still inconvenient to stably clamp shaft assemblies of various sizes. Therefore, a concentricity calibration auxiliary structure that can stably clamp shaft assemblies of different sizes is needed. Utility Model Content

[0010] Preferably, a first motor is fixedly installed on one side of the support plate on the right side, and the output end of the first motor rotates through the interior of the support plate on the right side and is fixedly connected to one end of the rotating column.

[0024] Please see Figure 1-4This utility model provides a technical solution: an auxiliary structure for calibrating the concentricity of a wire drawing machine shaft assembly, including an operating table 1. A concentricity calibration detector 9 is provided on one side of the operating table 1. A first slide groove 2 is provided at the top of the operating table 1. A first bidirectional threaded rod 3 is rotatably connected inside the first slide groove 2. First sliders 4 are threadedly sleeved at the opposite threads of the first bidirectional threaded rod 3. The outer surfaces of the two first sliders 4 are slidably connected to the inner wall of the first slide groove 2. Support plates 5 are fixedly connected to the top of the two first sliders 4. The relative positions of the two support plates 5 are... Each end is rotatably mounted with a rotating column 7. Each of the two rotating columns 7 has a clamping assembly at its opposite end. The clamping assembly includes a fixing block 8. A groove 11 is provided on one side of the fixing block 8. The upper and lower surfaces of the inner wall of the groove 11 are provided with second sliding grooves 13. The interior of each of the two second sliding grooves 13 is rotatably connected with a second bidirectional threaded rod 14. The opposite threads of the two second bidirectional threaded rods 14 are threaded with second sliders 15. Each of the four second sliders 15 has a sloped clamping block 12 fixedly mounted at its opposite end. The sloped ends of the four sloped clamping blocks 12 correspond to each other.

[0025] Furthermore, one end of each of the two second bidirectional threaded rods 14 is rotatably inserted through to one side of the fixing block 8, and one end of each of the two second bidirectional threaded rods 14 is fixedly connected to a handle 16, with the two handles 16 located on the upper and lower sides of the groove 11 respectively.

[0026] Furthermore, there are two clamping assemblies, both of which have the same structure and are respectively set at opposite ends of the two rotating columns 7.

[0027] Furthermore, a first motor 6 is fixedly installed on one side of the right support plate 5. The output end of the first motor 6 rotates through the interior of the right support plate 5 and is fixedly connected to one end of the rotating column 7.

[0028] Furthermore, a second motor 10 is fixedly installed on one side of the operating table 1. The output end of the second motor 10 rotates through the interior of the first slide groove 2 and is fixedly connected to one end of the first bidirectional threaded rod 3.

[0029] Furthermore, by starting the second motor 10, the output end of the second motor 10 drives the first bidirectional threaded rod 3 to rotate. Then, the first bidirectional threaded rod 3 drives the two first sliders 4 to move the corresponding support plates 5 relative to each other. Then, the two support plates 5 will drive their respective clamping assemblies to move, thereby adjusting the distance between the clamps at both ends of the shaft assembly. This allows for adjustment according to shaft assemblies of different lengths, thus facilitating the subsequent clamping process at both ends of the shaft assembly.

[0030] Furthermore, in the shaft clamping stage, the two ends of the shaft assembly to be calibrated are placed between the four inclined clamping blocks 12 on both sides. Then, the two handles 16 on one side are rotated, which in turn drive the corresponding second bidirectional threaded rods 14 to rotate. The two second bidirectional threaded rods 14 then drive the corresponding second sliders 15 to move the four inclined clamping blocks 12 relative to each other, thereby bringing the four inclined clamping blocks 12 closer to the shaft assembly. Then, the inclined structure of the inclined clamping blocks 12 is used to clamp the shaft assembly tightly from multiple directions, completing the stable clamping of the shaft assembly and thus fixing one end of the shaft assembly. Then, the other end of the shaft assembly is clamped and fixed again using the above steps.

[0031] Furthermore, by using the inclined structure of the four inclined clamping blocks 12 in conjunction with the movable design of the two clamping components, the inclined ends of the four inclined clamping blocks 12 can be stably contacted with the outer surface of the shaft assembly, thereby stably clamping shaft assemblies of different sizes, thus improving the adaptability of the concentricity calibration auxiliary structure.

[0032] Furthermore, after the shaft assembly is clamped, the detection head of the concentricity calibration tester 9 is placed against the surface of the shaft assembly, and then the first motor 6 is started. The output end of the first motor 6 drives the corresponding rotating column 7 to rotate, thereby driving the shaft assembly to rotate. Then the concentricity calibration tester 9 performs real-time detection on the rotating shaft assembly to obtain the concentricity data of the shaft assembly.

[0033] Structural Description:

[0034] Operating Platform 1: As the basic support platform of the entire calibration auxiliary structure, it provides a stable place for the installation and operation of other components. Its material and structural design must ensure sufficient strength and stability to support the various operations and forces during the calibration process of the shaft assembly.

[0035] Concentricity calibration tester 9: The core instrument used to detect the concentricity of shaft assembly. It obtains concentricity data in real time during the rotation of shaft assembly by contacting the surface of shaft assembly. Its detection accuracy directly affects the accuracy of shaft assembly calibration results (Here, the concentricity calibration tester 9 is prior art, and the detection device body in the existing patent publication number CN221147577U can be referred to).

[0036] First slide 2: Located at the top of the operating table 1, it provides guidance and track for the sliding of the first slider 4, enabling the first slider 4 to move smoothly on the operating table 1 along a predetermined direction, thereby driving the support plate 5 and the clamp assembly to adjust their positions.

[0037] The first bidirectional threaded rod 3 rotates inside the first slide groove 2 and is connected to the first slider 4 by its positive and negative threads, converting the rotational motion into the relative linear motion of the two first sliders 4, thereby realizing the precise adjustment of the spacing between the support plates 5 to adapt to shaft assemblies of different lengths.

[0038] First slider 4: threadedly connected to the first bidirectional threaded rod 3, sliding in the first groove 2 under the drive of the first bidirectional threaded rod 3, and at the same time serving as the connecting carrier of the support plate 5, driving the support plate 5 and the clamping assembly on it to move.

[0039] Support plate 5: Fixedly installed on the top of the first slider 4, it is used to support the rotating column 7 and the clamping assembly, providing a stable support structure for the clamping and rotation of the shaft assembly. Its rigidity and stability affect the smoothness of the shaft assembly during the inspection process.

[0040] Rotating column 7: Rotatably mounted on the opposite end of the support plate 5, serving as a rotating support component of the shaft assembly. Driven by the first motor 6, it drives the shaft assembly to rotate so that the concentricity calibration tester 9 can perform the test.

[0041] Fixed block 8: As the main structure of the clamping assembly, it provides a mounting base for other components. The groove 11, second slide 13 and other structures on it lay the foundation for realizing the clamping function of the shaft assembly.

[0042] Groove 11: Used to accommodate the shaft assembly to be calibrated, providing space for the shaft assembly, and working with the inclined clamping block 12 to clamp and fix the shaft assembly.

[0043] Second groove 13: It is formed on the upper and lower surfaces of the inner wall of groove 11 to provide a track for the sliding of second slider 15, so that second slider 15 can drive inclined clamp 12 to move in a predetermined direction under the drive of second bidirectional threaded rod 14.

[0044] The second bidirectional threaded rod 14: by rotating, it drives the second slider 15 to move. Its positive and negative thread design allows the two opposing second sliders 15 to move simultaneously to the middle or to both sides, thereby realizing the synchronous clamping or loosening of the four inclined clamping blocks 12 to adapt to shaft assemblies of different sizes.

[0045] The second slider 15 is threadedly connected to the second bidirectional threaded rod 14. Driven by the second bidirectional threaded rod 14, it slides in the second slide groove 13 and drives the inclined clamping block 12 to move, thereby achieving the clamping action on the shaft assembly.

[0046] Inclined clamping block 12: The inclined structure of the four inclined clamping blocks 12 tightly clamps the shaft assembly from multiple directions. Its inclined design can stably contact the outer surface of shaft assemblies of different sizes, improving the clamping adaptability of shaft assemblies of different specifications.

[0047] Handle 16: Allows operators to manually rotate the second bidirectional threaded rod 14 to control the clamping and loosening of the inclined clamping block 12.

[0048] First motor 6: Fixedly installed on one side of the right support plate 5, its output end is connected to the rotating column 7, providing power for the rotation of the rotating column 7 and the shaft assembly. By precisely controlling the motor speed and direction, the shaft assembly is ensured to rotate smoothly during the testing process.

[0049] The second motor 10 is fixedly installed on one side of the operating table 1. Its output end is connected to the first bidirectional threaded rod 3. By driving the first bidirectional threaded rod 3 to rotate, the distance between the two support plates 5 can be adjusted, thereby improving the operational convenience and efficiency of the shaft assembly clamping process.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
