Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an adjustable rotating clamp for processing a steering gear housing. Background Art

[0002] The automobile steering gear is an important component in the automobile steering system. It can increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. When the steering gear housing is processed by machine tools, it needs to be clamped and fixed by a fixture.

[0003] The application number in the existing public technology is: CN202322390521.X. A steering gear housing clamp, when in use, can place the steering gear housing on the connecting box and clamp it by means of a clamping component. When the state of the steering gear housing needs to be adjusted, it is only necessary to start the first motor through an external controller, and the output shaft of the first motor drives the driving gear to rotate, and the driving gear drives the meshing driven gear to rotate, thereby synchronously driving the rotating column to rotate on the bearing seat, so that the rotating column drives the connecting box and other components to rotate, thereby changing the direction of the steering gear housing, so that it can be processed in multiple directions, which is beneficial to ensuring the processing quality.

[0004] However, the above patent still has certain disadvantages when used: it only clamps the steering gear housing through a single set of clamping mechanisms arranged opposite to each other. During subsequent processing, the housing is easily offset to the other side without constraints due to the impact of the drill bit, thereby reducing the processing accuracy. At the same time, the steering column used for adjustment is not provided with a limiting structure. When the impact is transmitted to the steering column, it is easy to rotate, thereby causing the housing to rotate during processing. The overall stability of use is not very good, which further affects the quality of processing. The overall use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

A lower pressure seat 11 is arranged directly above the carrier 9, and several groups of connecting plates 16 are welded around the carrier 9 and the lower pressure seat 11, and a second electric hydraulic rod 17 is installed between the connecting plates 16. Limiting grooves 12 are provided in the middle of the surface of the carrier 9 and the middle of the surface of the lower pressure seat 11, and adjustment grooves 14 are symmetrically provided around the surface of the carrier 9. A bidirectional screw rod 18 is installed inside the adjustment groove 14, one end of the bidirectional screw rod 18 passes through one side of the carrier 9 and is connected to the drive motor 19, and clamps 10 are symmetrically sleeved on the outer periphery of both sides of the bidirectional screw rod 18, and a contact pad 15 is installed on the surface of one side of the clamp plate 10.

[0032] In one embodiment, a plurality of operation holes 13 are formed through the top surface of the lower pressing seat 11 .

[0033] In one embodiment, the contact pad 15 is made of rubber material. The contact pad 15 is provided to provide a certain buffering effect between the shell and the clamping plate 10, to avoid hard contact between metal structures, to reduce clamping damage, and to ensure the integrity of the shell.

[0034] In one embodiment, the position of the working hole 13 is the same as the processing position of the steering gear housing. The working hole 13 is opened to facilitate the insertion of the drill bit, thereby accurately processing and drilling the housing.

[0035] In one embodiment, a brake motor 3 is installed at one side of the bottom end of the drive box 2, and a drive gear 4 is installed at the output end of the brake motor 3. One end of the drive gear 4 is meshed and connected with a transmission gear 6, and the transmission gear 6 is located on the surface of the steering column 5. The transmission gear 6 and the drive gear 4 are both common gear structures and will not be described in detail here.

[0036] In one embodiment, the limit head 21 is made of metal material. The metal material ensures the use strength of the limit head 21 and prevents it from breaking due to torsion when inserted and fixed, thereby ensuring the locking effect of the steering column 5. The specific metal material can be adjusted according to needs, such as iron, steel, etc.

[0037] In one embodiment, a plurality of groups of mounting holes 22 are symmetrically provided around the surface of the fixing seat 1. The mounting holes 22 are provided to facilitate installation of the device at a lower position of the processing equipment and to facilitate subsequent drilling of the steering gear housing.

[0038] In one embodiment, the limit groove 12 structure is respectively the same as the upper and lower surface structures of the steering gear housing. The limit groove 12 structure is set to ensure that the bearing seat 9 and the lower pressure seat 11 can accommodate and limit the steering gear housing when limiting and fixing it, thereby preventing left and right movement and causing dislocation during subsequent processing, thereby ensuring the processing accuracy and improving the working effect.

[0039] Working principle: In actual use, when the steering gear housing needs to be processed, first, the two sets of drive motors 19 are operated to rotate the bidirectional screw rod 18 in the corresponding position, so as to move the clamping plate 10 outward. At this time, the personnel can place the steering gear housing into the limiting groove 12 on the surface of the bearing seat 9. Since the limiting groove 12 on the surface of the bearing seat 9 and the limiting groove 12 inside the lower pressure seat 11 have the same structure as the upper and lower surfaces of the steering gear housing, the steering gear housing can be limited and fixed by clamping the two. At the same time, the clamping plate 10 can be returned to its original position to abut against the surrounding surface positions of the steering gear housing. The device clamps the steering gear housing by upper and lower limiting and left and right extrusion fixing, which can effectively avoid misalignment during processing. The processing stability and processing quality are improved, and the working hole 13 correspondingly arranged on the surface of the lower pressure seat 11 can limit the position of the drill bit to avoid sliding of the drill bit and the shell during processing, which causes the deviation of the processing position, thereby ensuring the overall processing quality. During processing, the processing position of the shell can be adjusted by rotating the steering column 5, which is convenient for processing multiple hole positions at one time, thereby improving the use effect of the device. After the steering column 5 is adjusted, the limit head 21 can be inserted into the limit groove 12 on the surface of the steering column 5 through the ejection of the first electric hydraulic rod 8 on both sides, thereby realizing the locking of the steering column 5 to prevent rotation due to impact during processing and ensure the stability of the operation. The device as a whole has the advantages of strong processing stability, good processing effect and good clamping limit.
