Description

Technical Field

[0001] The utility model relates to the technical field of steering gear processing, in particular to a processing and fixing fixture for an automobile steering gear. Background Art

[0002] The automobile steering gear, also known as the steering machine or steering gear, is the most important component in the automobile steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. Commonly used types are rack and pinion type, worm crank pin type and recirculating ball type.

[0003] After searching, a clamp for processing an automobile steering gear disclosed by publication number CN215588508U includes a base, a first slide groove is opened inside the base, a connecting block is slidably connected inside the first slide groove, a support plate is fixedly connected to the upper surface of the connecting block, a first through hole is opened inside the support plate, a second slide groove is opened inside the first through hole, an adjusting ring is slidably connected inside the second slide groove, a fixing block is fixedly connected inside the adjusting ring, a first bidirectional screw is rotatably connected inside the fixing block, two ends of the first bidirectional screw are fixedly connected to a rotating plate, a connecting plate is threadedly connected to the outer surface of the first bidirectional screw, a clamping plate is fixedly connected to one side of the connecting plate, a second through hole is opened inside the clamping plate, a limiting rod is slidably connected inside the second through hole, one end of the limiting rod is fixedly connected to the abutment block, a first spring is sleeved on the outer surface of the limiting rod, a guide rod is fixedly connected inside the adjusting ring, the guide rod is slidably connected to the clamping plate, and a mounting plate is slidably connected inside the base.

[0004] The above-mentioned technical scheme has certain beneficial effects, but in actual use, when the first bidirectional threaded rod is driven to rotate by rotating the rotating plate and the top of the clamping plate is approached, the clamping plate as a whole is prone to tilt and cannot move normally on the outer surface of the guide rod. Even if it can move, its lower part cannot provide a stable clamping force when clamping and fixing the steering gear, and thus cannot stably clamp and fix the steering gear. For this reason, we propose a processing and fixing fixture for automobile steering gear. Utility Model Content

DETAILED DESCRIPTION

[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0024] Example:

[0025] like Figure 1-Figure 4 As shown, a fixing fixture for processing a steering gear of an automobile comprises a mounting frame 1, one end of the mounting frame 1 is fixedly connected to a servo motor 2, an output end of the servo motor 2 is fixedly connected to a bidirectional threaded rod 3, a fixing groove 4 is provided inside the mounting frame 1, a moving bottom block 5 is sleeved on the inner side of the fixing groove 4 and the outer side of the surface of the bidirectional threaded rod 3, a fixed limit block 6 is fixedly connected to the top of the moving bottom block 5, a first anti-slip pad 7 is fixedly connected to the inner top of the fixed limit block 6, and a clamping mechanism 8 is provided on the top of the moving bottom block 5.

[0026] The working principle of the above technical solution is as follows:

[0027] When in use, the servo motor 2 drives the bidirectional threaded rod 3 so that the bidirectional threaded rod 3 can rotate, so that the movable bottom block 5 moves in opposite directions on the inner side of the fixed groove 4 and the outer side of the surface of the bidirectional threaded rod 3 at the same time, driving the fixed limit block 6 and the clamping mechanism 8 to move, and adjust according to the length of the steering gear. After the adjustment is completed, the steering gear is inserted into the fixed limit block 6, and with the cooperation of the fixed limit block 6 and the clamping mechanism 8, the steering gear is clamped and fixed, which is easy to operate.

[0028] In another embodiment, if Figure 1 As shown, a mounting cavity 9 is opened inside the fixed limiting block 6 , a fixed limiting plate 10 is symmetrically arranged inside the mounting cavity 9 , and a lifting mechanism 11 is arranged between the bottom end of the fixed limiting plate 10 and the inside of the mounting cavity 9 .

[0029] It is convenient to lift the steering gear under the action of the lifting mechanism 11, and the clamping mechanism 8 moves downward, and no longer clamps and fixes the steering gear. At this time, the steering gear can be rotated and adjusted. After the adjustment is completed, the clamping mechanism 8 is reset and cooperates with the fixed limit block 6 again to clamp and fix the steering gear, which is easy to operate.

[0030] In another embodiment, if Figure 2 As shown, a movable connecting block 12 is movably connected between the end of the installation cavity 9 and the surface of the fixed limit block 6, a first fixed connecting block 13 is fixedly connected to the surface of the movable connecting block 12, and a fastening bolt 14 is movably connected between the first fixed connecting block 13 and the fixed limit block 6.

[0031] The movable connecting block 12 can be stuck in the inner side of the installation cavity 9, and the first fixed connecting block 13 fits with the surface of the fixed limit block 6 and is connected and fixed by the fastening bolts 14, so that the lifting mechanism 11 can be stably located inside the fixed limit block 6 for use, which is easy to operate.

[0032] In another embodiment, if Figure 2 As shown, the lifting mechanism 11 includes a movable mounting base plate 15, the top of which is fixedly connected to a first electric telescopic rod 16, the output end of which is fixedly connected to a connecting frame 17, and a rotating roller 18 is symmetrically provided on the inner side of the connecting frame 17.

[0033] The movable installation base plate 15 can be stuck in the inner side of the installation cavity 9, and the first electric telescopic rod 16 can push the connecting frame 17 and the rotating roller 18 upward to lift the steering gear, which is easy to operate.

[0034] In another embodiment, if Figure 3 As shown, the outer surface of the movable mounting base plate 15 fits with the inner side of the mounting cavity 9 and the bottom surface of the fixed limiting plate 10 , and one side of the movable mounting base plate 15 fits with one side of the movable connecting block 12 .

[0035] The movable installation base plate 15 can be stably clamped between the fixed limiting block 6 and the fixed limiting plate 10 for installation and use, and the movable connecting block 12 can limit the movable installation base plate 15 to prevent the movable installation base plate 15 from deflecting.

[0036] In another embodiment, if Figure 4 As shown, the clamping mechanism 8 includes a second electric telescopic rod 19, the top of the second electric telescopic rod 19 is fixedly connected to a second fixed connecting block 20, both ends of the second fixed connecting block 20 are fixedly connected to connecting clamping arms 21, and the inner side of the connecting clamping arm 21 is fixedly connected to a second anti-slip pad 22.

[0037] The second electric telescopic rod 19 is convenient for pushing the second fixed connecting block 20 upward, driving the connecting clamping arm 21 and the second anti-slip pad 22 to move upward, so that the second anti-slip pad 22 and the first anti-slip pad 7 and the connecting clamping arm 21 and the fixed limit block 6 are squeezed against each other, so that the steering gear can be clamped and fixed, and the operation is convenient.

[0038] In another embodiment, if Figure 1 As shown, one side of the connecting clamping arm 21 is in contact with the surface of the fixed limiting block 6 .

[0039] The connecting clamping arm 21 can stably move outside the surface of the fixed limit block 6, which is easy to operate.

[0040] The working principle of the utility model is as follows: during use, the servo motor 2 drives the bidirectional threaded rod 3, so that the movable bottom block 5 can move in opposite directions at the same time on the inner side of the fixed groove 4 and the outer side of the surface of the bidirectional threaded rod 3, and adjust according to the length of the steering gear. After the adjustment is completed, the steering gear is inserted into the inner side of the top end of the fixed limit block 6, and then the second electric telescopic rod 19 pushes the second fixed connection block 20, the connecting clamping arm 21 and the second anti-slip pad 22 upward to connect and cooperate with the fixed limit block 6 to clamp and fix the steering gear. Then, when the steering gear needs to be rotated and adjusted, the first electric telescopic rod 16 connects the frame 17 and the rotating roller 18 are pushed upward, so that the rotating roller 18 can lift the steering gear, and then the second electric telescopic rod 19 is contracted, driving the second fixed connecting block 20, the connecting clamping arm 21 and the second anti-slip pad 22 to contract, and the steering gear is no longer clamped and fixed. At this time, the steering gear is rotated. After the rotation adjustment is completed, the second electric telescopic rod 19 pushes the second fixed connecting block 20, drives the connecting clamping arm 21 and the second anti-slip pad 22 to reset, clamps and fixes the steering gear, and the first electric telescopic rod 16 drives the connecting frame 17 and the rotating roller 18 to contract, so that the commutator is processed again, which is easy to operate.

[0041] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
