Description

Technical Field

[0001] This invention relates to the field of steering gear sleeve assembly technology, and more particularly to an assembly device for automotive steering gear sleeve assembly. Background Technology

[0002] A steering gear is a machine that assists the driver in applying force while turning the steering wheel, reducing the effort required for steering and making driving easier and more convenient. It is mainly divided into rack and pinion steering and worm gear steering. Steering gear sleeves, based on their structural characteristics and main insulation medium, can be divided into single-insulation material sleeves and composite insulation sleeves, etc., and are frequently used in steering gears. Currently, fixing the sleeve involves the operator repeatedly adjusting the sleeve's posture using simple clamps, calibrating the sleeve's angle, and then tightening the positioning clips to complete the fixation, resulting in a slow assembly process for the sleeve assembly. Summary of the Invention

[0003] The purpose of this invention is to solve the problem mentioned in the background art of existing fixed sleeves, where operators repeatedly adjust the sleeve posture with the help of simple clamps, then calibrate the sleeve angle, and finally tighten the positioning buckle to complete the fixation, resulting in slow assembly of the sleeve assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An assembly device for automotive steering gear sleeve assembly includes a sleeve component and an assembly mechanism. The sleeve component includes a sleeve body and a tube body mounted on the sleeve body, the tube body having a pipe connector. The assembly mechanism includes a support platform, the support platform being provided with a support portion for fixing the sleeve body and an auxiliary portion for fixing the tube body, a clamping plate for fixing the sleeve body being mounted on the support block, and a limiting block corresponding to the pipe connector being provided on the auxiliary block.

[0005] Preferably, the support part includes a support block, the auxiliary part includes an auxiliary block, and the support block is provided with a recessed groove, which is used to limit the cam ring on the sleeve body.

[0006] Preferably, the card plate is rotatably connected to the support block, a slider is slidably connected to the support block, the slider is connected to the card plate through a connecting plate, and the two ends of the connecting plate are respectively hinged to the slider and the card plate.

[0007] Preferably, an adjusting screw is rotatably connected to the support block, and the adjusting screw is threadedly connected to the slider.

[0008] Preferably, an arc-shaped plate is fixed on the slider, and the arc-shaped plate is used to support the connecting part on the sleeve body.

[0009] Preferably, the arc-shaped plate extends upward.

[0010] Preferably, the auxiliary part includes an auxiliary block one, which has an arc-shaped groove for axial movement of the tube body.

[0011] Preferably, a limiting groove is formed on the upper side of the limiting block, and the limiting groove contacts the pipeline connector.

[0012] Preferably, the assembly mechanism further includes an auxiliary block two, on which an abutment block is provided, and the abutment block has an arc-shaped surface that contacts the outer surface of the tube.

[0013] Preferably, an adjusting screw is threadedly connected to the auxiliary block two, the end of the adjusting screw two is rotatably connected to the abutment block, and the abutment block is slidably connected to the auxiliary block two.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The recessed groove of the support part axially limits the cam ring of the casing body, and the clamping plate achieves radial fixation. At the same time, the arc plate increases the stability of the casing body after the rotating head is installed. The support part makes the casing body installed stably, eliminating the need for repeated manual adjustment of the posture, and the operation is simple.

[0015] The limiting groove of the auxiliary part limits the axial movement of the pipe connector, and the arc-shaped groove and the arc-shaped surface of the abutment block stabilize the pipe body radially, so that the pipe body can quickly determine the axial position through the position of the pipe connector and achieve radial stability through the abutment block, avoiding the tedious manual repeated angle calibration.

[0016] The assembly mechanism facilitates the positioning and installation of the sleeve body and the tube body, and also facilitates the installation of the steering head, thereby improving the assembly efficiency of the steering gear sleeve assembly and reducing the difficulty of operation.

[0030] Please see Figures 1-7An assembly device for an automotive steering gear sleeve assembly includes a sleeve component 1 and an assembly mechanism 2. The sleeve component 1 includes a sleeve body 11 and a pipe body 12 mounted on the sleeve body 11. The pipe body 12 has a pipe connector 13. The sleeve component 1 has a steering head 3, and the pipe is used to connect the pipe body 12 and the steering head 3. The steering gear sleeve component 1 is prior art.

[0031] Assembly mechanism 2 includes a support platform 21, on which a support part 22 for fixing the sleeve body 11 and an auxiliary part 23 for fixing the tube body 12 are provided. The support part 22 includes a support block 221, on which a retaining plate 222 for fixing the sleeve body 11 is installed. The retaining plate 222 is an arc-shaped plate. The support block 221 is provided with a recessed groove 223, which is used to limit the cam ring 15 on the sleeve body 11. The retaining plate 222 cooperates with the support block 221 to fix the sleeve body 11. There are two cam rings 15, so the recessed groove 223 is provided one-to-one with the cam ring 15. Both arc-shaped parts of the cam ring 15 are partially located in the recessed groove 223 to prevent the sleeve body 11 from rotating, which is beneficial to the stability of the sleeve 1 and also makes installation convenient, as the sleeve body 11 can be placed into the recessed groove 223.

[0032] The clamping plate 222 is rotatably connected to the support block 221. A slider 224 is slidably connected to the support block 221. The slider 224 is connected to the clamping plate 222 via a connecting plate 225. The two ends of the connecting plate 225 are hinged to the slider 224 and the clamping plate 222, respectively. The movement of the slider 224 via the connecting plate 225 causes the clamping plate 222 to rotate.

[0033] An adjusting screw 226 is rotatably connected to the support block 221. The adjusting screw 226 is threadedly connected to the slider 224. The slider 224 is moved by adjusting the screw 226. When the clamping plate 222 covers the sleeve body 11 and contacts the support block 221, it sends feedback to the adjusting screw 226, causing the adjusting screw 226 to stop rotating, indicating that the sleeve body 11 has reached the position.

[0034] An arc-shaped plate 227 is fixed on the slider 224. The arc-shaped plate 227 is used to support the connecting part 14 on the sleeve body 11. The arc-shaped plate 227 supports the connecting part 14 and has the function of preventing the sleeve body 11 from flipping over.

[0035] Furthermore, the arc-shaped plate 227 extends upward. A connecting portion 14 is used to connect the steering head 3, and the lower side of the steering head 3 also has a connecting portion 14. The two connecting portions 14 are fixed together by bolts. The upward-extending arc-shaped plate 227 facilitates the alignment of the two connecting portions 14 and also facilitates the connection between the steering head 3 and the sleeve body 11. Specifically, after the connecting portion 14 of the steering head 3 aligns with the connecting portion 14 on the sleeve body 11, the curvature of the arc-shaped plate 227 allows the two connecting portions 14 to be aligned, facilitating the connection between the steering head 3 and the sleeve body 11.

[0036] The auxiliary part 23 includes an auxiliary block 231, on which a limiting block 232 corresponding to the pipe connector 13 is provided. The auxiliary block 231 has an arc-shaped groove 233 for the axial movement of the pipe body 12.

[0037] A limiting groove 234 is provided on the upper side of the limiting block 232. The limiting groove 234 contacts the pipe connector 13. The limiting groove 234 is used to limit the axial movement of the pipe body 12, and also to position the pipe body 12. At the same time, it is also used to determine the position of the pipe connector 13.

[0038] Furthermore, to stabilize the tube body 12, the assembly mechanism 2 also includes an auxiliary block 235. The auxiliary block 235 has an abutment block 236 with an arc-shaped surface 237 that contacts the outer surface of the tube body 12. An arc-shaped groove 233 is also formed on the auxiliary block 235, and the arc-shaped surface 237 engages with the arc-shaped groove 233 to limit the movement of the tube body 12. The combined arc of the arc-shaped surface 237 and the arc-shaped groove 233 exceeds half the circumference of the tube body 12.

[0039] A second adjusting screw 238 is threaded onto the auxiliary block 235. The end of the adjusting screw 238 is rotatably connected to the abutment block 236, and the abutment block 236 is slidably connected to the auxiliary block 235. After the abutment block 236 abuts against the pipe body 12, it stabilizes the pipe body 12 in the circumferential direction. The upper side of the abutment block 236 also has a limiting groove 234 for reinforcing the pipe body 12.

[0040] In use, the cam ring 15 on the sleeve body 11 is placed in the recessed groove 223. At this time, the sleeve body 11 is axially stable. Then, the adjusting screw 226 is rotated to move the slider 224. The slider 224 causes the clamping plate 222 to flip through the connecting plate 225. When the clamping plate 222 covers the sleeve body 11 and contacts the support block 221, the clamping plate 222 stops flipping and feeds back to the adjusting screw 226, causing the adjusting screw 226 to stop rotating. This indicates that the sleeve body 11 has reached the position, and the radial fixation of the sleeve body 11 is completed. During the flipping process of the clamping plate 222, the slider 224 moves with the arc plate 227. When the clamping plate 222 stops, the arc plate 227 contacts the connecting part 14. Then, the tube body 12 is placed on the arc groove 233 of the auxiliary block 1 231 and moved axially. Then, the tube body 12 is rotated so that the pipe connector 13 enters the limiting groove 234, thereby stabilizing the tube body 12 axially and determining the position of the tube body 12. Finally, the adjusting screw 238 is rotated so that the abutment block 236 moves and the arc surface 237 on the abutment block 236 contacts the outer surface of the tube body 12, thereby stabilizing the tube body 12 radially.

[0041] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
