Description

Technical Field

[0001] This utility model relates to the field of steering gear technology, specifically a steering gear housing inspection tool. Background Technology

[0002] The housing contains a rack hole through which a steering rack passes. The housing also has a gear mounting section with a bearing hole that communicates with the rack hole. A steering gear is installed in the bearing hole. The center distance and angle between the rack hole and the bearing hole are crucial for the proper engagement of the steering gear and rack. The angle is the angle between the center lines of the steering gear and rack, and the center distance is the distance between their respective center lines. These angles and center distances are reflected on the housing as the angle and distance between the center lines of the bearing hole and the rack hole. Excessive angular error will prevent the gear and rack from engaging properly. When the center distance is too large, the steering gear and the steering rack will not mesh properly, making it difficult to output torque on the steering wheel, increasing the transmission clearance, and producing a knocking sound between the teeth of the steering gear and the teeth of the steering rack. When the center distance is too small, the steering gear or steering rack will be difficult to assemble into the housing. Even if it is assembled into the housing, the steering gear will not be able to rotate at all due to excessive meshing, or the rotational torque will be too large and not meet the requirements. Therefore, testing the center distance and included angle between the rack hole and the bearing hole is an important part of the steering gear housing production.

[0003] The existing Chinese patent with publication number CN219161205U describes a technical solution comprising: a placement seat assembly on a testing platform, with the steering gear located within the placement seat assembly during testing; a stabilizing mechanism installed at the bottom of the testing platform, the stabilizing mechanism including two stabilizing hands on both sides for stabilizing the steering gear housing; a mounting box located below the testing platform, with a forward / reverse motor fixedly installed inside the mounting box; a drive shaft installed at the output end of the forward / reverse motor; reciprocating screws rotatably mounted on both sides of the mounting box, the threads of the two reciprocating screws having opposite directions; the two reciprocating screws and the drive shaft being connected via a bevel gear assembly; and threaded mounting blocks threaded onto the reciprocating screws. This invention, through this configuration, can position and stabilize the steering gear housing placed on the placement seat assembly.

[0004] The problem with the aforementioned technologies is that the device cannot adjust the position of the fixing plate for steering gears of different lengths, making it inconvenient to test steering gears of different lengths. Utility Model Content

[0005] The purpose of this utility model is to provide a steering gear housing inspection tool. By using this device, the problem that the current device cannot adjust the position of the fixing plate for steering gears of different lengths, and is not convenient for inspecting steering gears of different lengths is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steering gear housing inspection fixture, including an operating table with a slot, a fixed frame on the lower side of the operating table, a steering gear housing placed on the upper side of the operating table, and an inspection fixture on the operating table. The inspection fixture includes a fixed plate, on which a positioning rod is movably mounted. The fixed plate is movably mounted on the upper surface of the operating table. A fixed plate is mounted on the upper side of the operating table away from the fixed plate, and a positioning rod is movably mounted on the fixed plate. A fixed plate is mounted on one side of the fixed plate, and the fixed plate is mounted on the upper side of the operating table. A positioning rod is movably mounted on the fixed plate. An adjustment component is provided inside the fixed frame, and a clamping component is provided on the operating table. The adjustment component includes a slide rail, which is installed inside the fixed frame. A sliding block is provided inside the slide rail, and the sliding block matches the slot. The upper end of the sliding block is fixedly connected to the fixed plate. A threaded rod is installed through the upper part of the sliding block, and the threaded rod is rotatably connected inside the slide rail. The threaded rod is threadedly connected to the sliding block.

[0007] Adjusting the threaded rod allows the sliding block to move horizontally along the groove within the slide rail, thereby causing the fixed plate at the upper end of the sliding block to move laterally. By adjusting the distance from the center of the operating table, the position can be changed for steering gear housings of different lengths, thus facilitating the inspection of steering gear housings of different lengths.

[0008] Preferably, the operating platform has a slot two, a fixing frame two is provided on the lower side of the operating platform at the slot two, and four support columns are installed on the lower side of the operating platform.

[0009] The support columns provide support for the control panel.

[0010] When inspecting the steering gear housing, the steering gear housing needs to be placed on the clamping assembly, adjusted in position, and then fixed by the clamping assembly. Positioning rod one, positioning rod two, and positioning rod three are then inserted into the right end of the rack hole, the bearing hole, and the left end of the rack hole of the steering gear housing, respectively.

[0011] Preferably, the clamping assembly includes a rack plate 1, which is disposed within a fixed frame 2. The lower side of the rack plate 1 is movably connected to the bottom of the inner wall of the fixed frame 2. A gear is disposed on one side of the rack plate 1, and a rack plate 2 is disposed on one side of the gear. The lower side of the rack plate 2 is movably connected to the bottom of the inner wall of the fixed frame 2. The rack plate 1 and the gear are meshed together, and the gear and the rack plate 2 are meshed together. A connecting block 1 is mounted on the upper side of the rack plate 1, and a connecting block 2 is mounted on the upper side of the rack plate 2. The connecting blocks 1 and 2 are adapted to the slot 2. A clamping block 1 is mounted on the upper side of the connecting block 1, and a clamping block 2 is mounted on the upper side of the connecting block 2. A motor is mounted on the lower side of the gear, and the lower side of the motor is mounted through the fixed frame 2. The gear is mounted on the output end of the motor.

[0012] When the motor is started, the output end of the motor drives the gear to rotate clockwise, causing rack plate one to move towards one end of clamping block one and rack plate two to move towards one end of clamping block two. This causes clamping blocks one and clamping blocks two to move away from each other, and vice versa, clamping blocks one and clamping blocks two to move closer to each other, thus achieving the function of clamping and releasing the steering gear housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model proposes a steering gear housing inspection fixture. The adjustment component includes a slide rail, which is installed inside a fixed frame. A sliding block is provided inside the slide rail, and the sliding block matches a slot. The upper end of the sliding block is fixedly connected to a fixed plate. A threaded rod is installed through the upper part of the sliding block, and the threads of the sliding block and the threaded rod are matched. By adjusting the threaded rod, the sliding block can move horizontally along the slot in the slide rail, thereby driving the fixed plate at the upper end of the sliding block to move laterally. By adjusting the distance from the center of the operating table, the position can be changed for steering gear housings of different lengths, thus facilitating the inspection of steering gear housings of different lengths.
