Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and particularly relates to a bushing automatic height-adjusting clamp seat. Background Technique

[0002] An automobile suspension tie rod is one of the main components of an automobile, and its quality and reliability will directly affect the driving experience of the automobile. As a moving part, the automobile suspension tie rod is prone to wear during long-term friction. When the wear of the connecting end of the tie rod reaches a certain degree, it must be replaced. Therefore, in the prior art, a bushing with better wear resistance is often equipped at the connecting end of the automobile suspension tie rod to protect the connecting end of the automobile suspension tie rod through the bushing.

[0003] The bushing is usually annular and made of wear-resistant material, and mainly plays a cushioning role for the automobile suspension tie rod. Since the assembly accuracy requirements between the bushing and the automobile suspension tie rod are relatively high, the bushing also needs to go through multiple processes such as inspection, oiling, and painting after being produced. In these subsequent processing processes, the bushing needs to be kept in a vertical state. Although the existing conventional fixtures can keep the bushing vertical by clamping, during inspection, oiling, and painting, the contact part between the bushing and the fixture will affect the processing, resulting in incomplete oiling and painting. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic height-adjusting clamp seat that can not only support the bushing to keep the bushing in a vertical state, but also reduce the contact area with the bushing during subsequent processing and reduce the influence on processing.

[0005] To solve the above problems, the utility model provides a bushing automatic height-adjusting clamp seat, which includes a positioning column, a shelf, a bottom plate, a guide post and a spring. The shelf is fixedly arranged and suspended below. The shelf is provided with a guide hole and a positioning hole that both penetrate vertically. The middle part of the guide post is slidably inserted into the guide hole, and the middle part of the positioning column is slidably inserted into the positioning hole. The upper ends of the guide post and the positioning column both extend above the shelf. The upper end of the positioning column is used for being inserted into the inner hole of the bushing. The upper end of the guide post is provided with a limiting part. The spring is located above the shelf and sleeved on the guide post. The upper end of the spring abuts against the limiting part of the guide post and the lower end abuts against the shelf. The lower ends of the guide post and the positioning column both extend below the shelf, and the lower ends of the guide post and the positioning column are connected by the bottom plate.

[0006] Compared with the prior art, in the above solution, the bushing is supported by the shelf. Meanwhile, by providing a guide hole and a positioning hole on the shelf, in the initial state, the spring applies an upward thrust to the guide post, such that the upper ends of both the guide post and the positioning post are kept above the shelf. At this time, the upper end of the positioning post is used to insert into the inner hole of the bushing so that the bushing can be kept in a state with a vertical axis. When a downward pressure is applied to the guide post, the guide post descends and drives the positioning post to descend through the bottom plate, so that the upper end of the positioning post can be disengaged downward from the corresponding inner hole of the bushing, facilitating various processing operations on the bushing.

[0007] In an improved solution, there are two guide holes on the shelf and they are spaced apart. Each guide hole is slidably inserted with a guide post. The positioning hole is located at a position between the two guide holes on the shelf, thus making the structure more stable.

[0008] In an improved solution, it further includes a lifting drive member arranged at the side position of the shelf and a lifting frame driven by the lifting drive member to lift. The lifting frame is located above the guide post. The lifting frame is used to press against the guide post under the drive of the lifting drive member, so as to realize the automatic adjustment of the height of the guide post by driving the lifting frame to press against the guide post by the lifting drive member.

[0009] In an improved solution, it further includes a rotary motor and a rotary table. The rotary motor is fixedly arranged and its output shaft is upward. The middle part of the rotary table is connected to the output shaft of the rotary motor. The rotary table is provided with a mounting part for connecting the shelf, so as to drive the rotary table to rotate with the vertical axis by the rotary motor, realizing the position movement of the shelf, facilitating various processing of the bushing.

[0010] In an improved solution, there are multiple mounting parts and they are distributed along the circumferential direction of the rotary table, so that multiple shelves can be arranged on the rotary table, improving the processing efficiency of the bushing.

[0011] In an improved solution, a through groove penetrating vertically is opened at the position of the rotary table corresponding to the mounting part, and the through groove can allow the bottom plate to pass through.

[0012] In an improved solution, the upper end of the positioning post is provided with a chamfer or a fillet, so that the upper end of the positioning post can be more accurately inserted into the inner hole of the bushing. Description of the Drawings

[0023] The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Please refer to Figures 1-4, an automatic height-adjusting clamp seat for a bushing provided by an embodiment of the present utility model includes a positioning post b11, a shelf b12, a bottom plate b13, a guide post b14, and a spring b15. The shelf b12 is fixedly arranged and suspended below. The shelf b12 is provided with a guide hole b122 and a positioning hole b121 that both penetrate vertically. The middle part of the guide post b14 is slidably inserted into the guide hole b122, and the middle part of the positioning post b11 is slidably inserted into the positioning hole b121. The upper ends of the guide post b14 and the positioning post b11 both extend above the shelf b12. The upper end of the positioning post b11 is used to be inserted into the inner hole of the bushing. The upper end of the guide post b14 is provided with a limiting portion b141. The spring b15 is located above the shelf b12 and sleeved on the guide post b14. The upper end of the spring b15 abuts against the limiting portion b141 of the guide post b14 and the lower end abuts against the shelf b12. The lower ends of the guide post b14 and the positioning post b11 both extend below the shelf b12, and the lower ends of the guide post b14 and the positioning post b11 are connected by the bottom plate b13.

[0025] The above solution supports the bushing through the shelf b12. At the same time, by opening the guide hole b122 and the positioning hole b121 on the shelf b12, in the initial state, the spring b15 exerts an upward thrust on the guide post b14, so that the upper ends of the guide post b14 and the positioning post b11 both remain above the shelf b12. At this time, the upper end of the positioning post b11 is used to insert into the inner hole of the bushing so that the bushing can be kept in a vertically axis state; when a downward pressure is applied to the guide post b14, the guide post b14 descends and drives the positioning post b11 to descend through the bottom plate b13, so that the upper end of the positioning post b11 can be disengaged downward from the corresponding inner hole of the bushing, facilitating various processing operations on the bushing.

[0026] As an improvement to this embodiment, there are two guide holes b122 on the shelf b12 and they are spaced apart. Each guide hole b122 is slidably inserted with a guide post b14, and the positioning hole b121 is located at the position between the two guide holes b122 on the shelf b12, so that the structure is more stable.

[0027] As an expansion solution to this embodiment, it further includes a lifting drive member f5 arranged at the side position of the shelf b12 and a lifting frame f6 driven by the lifting drive member f5 to lift. The lifting frame f6 is located above the guide post b14. The lifting frame f6 is used to press against the guide post b14 under the drive of the lifting drive member f5. Thus, by driving the lifting frame f6 to press against the guide post b14 by the lifting drive member f5, the automatic adjustment of the height of the guide post b14 is realized.

[0028] As another expansion solution for this embodiment, it further includes a slewing motor b3 and a slewing table b2. The slewing motor b3 is fixedly arranged with its output shaft facing upward. The middle part of the slewing table b2 is connected to the output shaft of the slewing motor b3. The slewing table b2 is provided with a mounting part b21 for connecting the shelf b12, so that the slewing table b2 is driven by the slewing motor b3 to rotate with the vertical axis as the axis, realizing the position movement of the shelf b12, which is convenient for various processing of the bushing.

[0029] Furthermore, there are multiple mounting parts b21 and they are distributed along the circumferential direction of the slewing table b2, so that multiple shelves b12 can be arranged on the slewing table b2, improving the processing efficiency of the bushing.

[0030] A through groove b22 penetrating vertically is formed at the position of the slewing table b2 corresponding to the mounting part b21. The through groove b22 can allow the bottom plate b13 to pass through, so as to ensure that the bottom plate b13 can freely move up and down along with the guide post b14.

[0031] Preferably, the upper end of the positioning post b11 is provided with a chamfer or a fillet, so that the upper end of the positioning post b11 can be more accurately inserted into the inner hole of the bushing.
