Description

Technical Field

[0001] This utility model relates to the field of leveling tooling technology, specifically to a rear axle housing leveling device. Background Technology

[0002] The rear axle housing is an important component of the rear axle of a car. It supports the weight of the vehicle, bears the road reaction forces and torques transmitted from the wheels, and transmits them to the frame or body via the suspension. At the same time, it also bears the reaction forces and torques of traction, braking force, lateral force, and vertical force transmitted from the drive wheels.

[0003] When machining the air brake bracket connecting bolt holes in the rear axle housing assembly of an automotive air brake, the positional relationship between the bracket connecting bolt holes and the axis and plane, the distance from the plane to the center axis due to previous machining errors, and the gaps when leveling the plane result in large positional errors when machining the bracket connecting bolt holes. This affects the assembly of the brake camshaft, causing asymmetry in the vehicle's brake clearance, brake deviation, and fishtailing. Utility Model Content

[0004] The purpose of this utility model is to provide a rear axle housing leveling device that can effectively solve the technical problem in the prior art where gaps exist during flat leveling, resulting in large positional errors when machining the bolt holes of the bracket connection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A rear axle housing leveling device, comprising:

[0007] Support unit for mounting on the control panel to support the rear axle housing;

[0008] An adjustment unit installed on the control panel to adjust the rear axle housing;

[0009] The adjustment unit includes an upper slide plate, a lower slide plate, and a drive assembly. The surfaces of the upper and lower slide plates that are in contact with each other are provided with inclined surfaces. The inclined surfaces of the upper and lower slide plates slide in a sliding fit with each other. The drive assembly is connected to the upper slide plate and is used to drive the upper slide plate to move. The top surface of the upper slide plate is used to contact the rear axle housing.

[0010] Furthermore, a guide unit is provided between the upper and lower sliding plates.

[0011] The guide unit includes a groove on the inclined surface of the lower slide plate and a protrusion on the inclined surface of the upper slide plate that slides in cooperation with the groove.

[0012] Furthermore, the drive assembly includes a vertical plate and a screw. The vertical plate is disposed on the side of the lower slide plate, and the screw is threaded onto the vertical plate. A slot is provided on the screw near its end, and a limiting groove is provided on the upper slide plate. The limiting groove is a T-shaped groove, and the end of the screw extends into the limiting groove. The slot and the T-shaped groove are movably engaged, allowing the upper slide plate and the screw to move vertically relative to each other.

[0013] The screw end is equipped with a handle, handwheel, or flat rectangular structure.

[0014] Further optimization involves the support unit comprising a first support unit and a second support unit, which are located at both ends of the adjustment unit to provide support for the ends of the rear axle housing.

[0015] The first support unit and the second support unit have the same structure, both including a first base with a V-shaped notch, and the first base is used to be installed on the operating table.

[0016] Furthermore, the first support unit and the second support unit also include a pad, which is disposed within a V-shaped notch.

[0017] The first support unit and the second support unit further include a second base, with the first base mounted on the second base, and the second base used for mounting on the operating table.

[0018] Further optimization involves sliding the first base onto the second base and securing it with a fixing unit.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In practical use, this invention utilizes a support unit for support, and an adjustment unit to level the rear axle housing. A drive assembly moves the upper slide plate on the lower slide plate. Because both the upper and lower slide plates have inclined surfaces, the relative sliding of the upper and lower slide plates causes a change in the height of the upper slide plate. This allows the top surface of the upper slide plate to contact the rear axle housing, achieving leveling and ensuring the lower plane of the rear axle housing is horizontal and parallel to the machined surface. The change in plane height eliminates gaps between the plane and the upper slide plate support, facilitating drilling and solving the problems of rear axle housing bracket hole position errors and assembly / vehicle quality issues caused by gaps during leveling.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] See Figures 1-5 This embodiment discloses a rear axle housing leveling device, including a support unit 101 and an adjustment unit 104. The support unit 101 is used to support the rear axle housing 105 by being installed on the operating table 121; the adjustment unit 104 is installed on the operating table 121 to adjust the position of the rear axle housing 105.

[0037] The adjustment unit 104 includes an upper slide plate 106, a lower slide plate 107, and a drive assembly 108. The upper slide plate 106 and the lower slide plate 107 are both provided with inclined surfaces 109 on their contact surfaces. The inclined surfaces 109 of the upper slide plate 106 and the lower slide plate 107 slide in a sliding engagement with each other. The drive assembly 108 is connected to the upper slide plate 106 and is used to drive the upper slide plate 106 to move. The top surface of the upper slide plate 106 is used to contact the rear axle housing 105.

[0038] In practical use, this invention utilizes a support unit 101 for support, and an adjustment unit 104 to level the rear axle housing 105. A drive assembly 108 drives the upper slide plate 106 to move on the lower slide plate 107. Since both the upper and lower slide plates 106 and 107 have inclined surfaces 109, relative sliding causes a change in the height of the upper slide plate 106, ensuring its top surface contacts the rear axle housing 105 and levels it, thus guaranteeing the lower plane of the rear axle housing 105 is horizontal and the machined surface is parallel to the lower plane. The change in plane height eliminates gaps between the support and the upper slide plate 106, facilitating drilling and solving the problems of positional errors in the rear axle housing 105 bracket holes caused by gaps during leveling, as well as assembly and overall vehicle quality issues.

[0039] A guide unit is provided between the upper sliding plate 106 and the lower sliding plate 107.

[0040] In this embodiment, the guide unit includes a groove 110 disposed on the inclined surface 109 of the lower slide plate 107 and a protrusion 111 disposed on the inclined surface 109 of the upper slide plate 106 and slidingly engaged with the groove 110.

[0041] The guide unit makes the upper slide plate 106 more stable when sliding.

[0042] The drive assembly 108 includes a vertical plate 112 and a screw 113. The vertical plate 112 is disposed on the side of the lower slide plate 107, and the screw 113 is threaded onto the vertical plate 112. A slot 114 is provided on the screw 113 near its end. A limiting groove 115 is provided on the upper slide plate 106. The limiting groove 115 is a T-shaped groove. The end of the screw 113 extends into the limiting groove 115, and the slot 114 and the T-shaped groove are movably engaged, so that the upper slide plate 106 and the screw 113 can move vertically relative to each other.

[0043] After the slot 114 and the limiting slot 115 are engaged, the upper slide plate 106 is laterally limited. When the upper slide plate 106 moves, the height of the upper slide plate 106 will increase. After the screw 113 rotates, it will move to drive the upper slide plate 106. The T-slot is provided to ensure that the upper slide plate 106 moves and makes room for other parts, so as to ensure the stable movement of the upper slide plate 106.

[0044] Furthermore, in actual use, the slope of the inclined plane 109 is set to 6-8°, preferably 7° in this embodiment. Under the action of downward pressure, it can generate self-locking anti-reverse, and the upper sliding plate 106 will not change in height due to downward pressure.

[0045] In practical use, the vertical displacement of the upper slide plate 106 is achieved by controlling the movement of the screw 113. For example, if the screw 113 moves by 10mm, the height changes by 1.2mm, which can smooth and position a plane with a height error within the range of 1.2mm.

[0046] Furthermore, the end of the screw 113 is provided with a handle 116, a handwheel, or a flat rectangular structure to improve the convenience of operation.

[0047] The support unit 101 includes a first support unit 102 and a second support unit 103. The first support unit 102 and the second support unit 103 are located at both ends of the adjustment unit 104 to support the end of the rear axle housing 105.

[0048] Furthermore, the first support unit 102 and the second support unit 103 have the same structure, both including a first base 117, on which a V-shaped notch 120 is provided, and the first base 117 is used to be installed on the operating table 121.

[0049] In actual use, the first support unit 102 and the second support unit 103 also include a pad 119, which is disposed in the V-shaped notch 120.

[0050] After the height of the upper slide plate 106 changes, the axis of the rear axle housing 105 assembly rotates within the V-shaped notch 120 to ensure that the rear axle housing 105 is straightened.

[0051] Furthermore, in some preferred embodiments, the first support unit 102 and the second support unit 103 also include a second base 118, with the first base 117 mounted on the second base 118, and the second base 118 used for mounting on the work surface 121.

[0052] Furthermore, the first base 117 is slidably mounted on the second base 118 and is fixed by a fixing unit.

[0053] In practical use, the positions of the first support unit 102 and the second support unit 103 can be adjusted as needed to accommodate different models of rear axle housings 105, thereby improving the overall applicability of the device.

[0054] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
