Description

Technical Field

[0001] This utility model relates to the field of tooling technology for machining main reducer housings, and in particular to a clamping tooling for main reducer housings. Background Technology

[0002] Currently, the main reducer is a crucial component of the automotive drive axle assembly. Its primary function is to amplify the torque from the transmission and drive shaft while simultaneously reducing speed and changing the direction of torque transmission. The main reducer consists of several pairs of reduction gears. Power is input from the driving gear and output through the driven gear, thus meeting the kinematic requirements of vehicle operation. The drive axle's intermediate axle main reducer mainly comprises a reduction housing assembly, a differential assembly, a driving bevel gear assembly, and an inter-axle differential assembly. Its main function is to reduce speed and increase torque. All subassemblies transmit torque through gear pairs.

[0003] In the existing technology, there is a Chinese utility model patent with publication number CN213197277U entitled "A Main Reducer Housing". In this patent, the main reducer housing workpiece is fixed to a table by a rotating pressure plate. This fixing method has certain drawbacks. When fixing the workpiece, the bottom end face of the workpiece must be pressed firmly against the table surface, then the top end face of the workpiece must be machined, and finally it must be flipped and fixed again to machine the other end face. This makes the workpiece flipping and re-centering operations cumbersome and labor-intensive. There is an urgent need for a main reducer housing clamping fixture that is easy to operate and improves efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping fixture for the main reducer housing, so as to solve the problem that the existing clamping fixtures require flipping and re-aligning the main reducer housing, which is cumbersome and laborious.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A clamping fixture for a main reducer housing includes a base plate, a slider, a support plate, and a clamping member. The sliders are symmetrically arranged and slidably mounted on the base plate. The sliders are fixed to the base plate by bolts and nuts. The support plates are symmetrically arranged at both ends of the sliders. The clamping member is arranged on the support plate and presses the periphery of the main reducer housing onto the support plate.

[0006] A further technical solution is as follows: the clamping component includes an L-shaped rod, a cylinder, and a pressure block. The L-shaped rod is disposed on the support plate, the cylinder is disposed vertically downward on the L-shaped rod, and the pressure block is disposed on the power output end of the cylinder.

[0007] A further technical solution is: a limiting groove is provided on the pressure block, and a limiting protrusion adapted to the limiting groove is provided around the main reducer housing.

[0008] A further technical solution is that the upper surfaces of the base plate and the support plate are on the same horizontal plane.

[0009] A further technical solution is that the slider is symmetrically provided with side plates that are adapted to the base plate.

[0010] A further technical solution is: a strip groove is provided on the base plate, and the bolt between the slider and the base plate is located in the strip groove.

[0011] A further technical solution is: the base plate is a cross plate, the cross plate is provided with a positioning post, a positioning sleeve is slidably installed on the positioning post, and the positioning sleeve is adapted to the hole on the main reducer housing.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This utility model proposes a clamping fixture for a main reducer housing. This clamping fixture can perform double-end face machining by clamping the main reducer housing only once. Especially when machining the bottom end face of the main reducer housing, the support plate and the clamping parts clamp the main reducer housing together, which does not hinder the drilling of the periphery of the end face of the main reducer housing. That is, there is no need to flip the main reducer housing and re-align it, which greatly simplifies the machining of the main reducer housing and saves time and effort. Attached Figure Description

[0024] This implementation example Figure 1 and Figure 2 As shown, a clamping fixture for a main reducer housing includes a base plate 1, a slider 2, a support plate 3, and a clamping member 4. The slider 2 is symmetrically arranged and slidably mounted on the base plate 1. The slider 2 and the base plate 1 are fixed together by bolts and nuts. The support plate 3 is symmetrically arranged at both ends of the slider 2. The clamping member 4 is arranged on the support plate 3 and clamps the periphery of the main reducer housing 5 onto the support plate 3.

[0025] The working process of this utility model is as follows: First, the base plate 1 is installed on the machining platform of the machine tool. Then, the main reducer housing 5 is placed on the base plate 1 and the support plate 3. The position of the slider 2 is adjusted according to the size of the main reducer housing 5 to ensure that the clamping member 4 is aligned with the periphery of the main reducer housing 5. Finally, the periphery of the main reducer housing 5 is clamped by the clamping member 4. This clamping fixture can perform double-end face machining after clamping the main reducer housing 5 once. Especially when machining the bottom end face of the main reducer housing 5, the support plate 3 and the clamping member 4 clamp the main reducer housing 5 together, which does not hinder the drilling of the periphery of the end face of the main reducer housing 5. That is, there is no need to flip the main reducer housing and re-align it, which greatly simplifies the machining of the main reducer housing and saves time and effort.

[0026] Preferably, the clamping component 4 includes an L-shaped rod 6, a cylinder 7, and a pressure block 8. The L-shaped rod 6 is mounted on the support plate 3, the cylinder 7 is mounted vertically downward on the L-shaped rod 6, and the pressure block 8 is mounted on the power output end of the cylinder 7.

[0027] The L-shaped rod 6 can be fixed or rotated on the support plate 3, and the output pressure of the cylinder 7 presses the periphery of the main reducer housing with the help of the pressure block 8.

[0028] It is worth noting that the L-shaped rod 6 is best set to rotate. When the main reducer housing 5 is installed, the L-shaped rod 6 can be rotated to avoid the placement of the main reducer housing 5.

[0029] Preferably, the pressure block 8 is provided with a limiting groove 81, and the periphery of the main reducer housing 5 is provided with a limiting protrusion 51 that matches the limiting groove 81.

[0030] The limiting groove 81 on the pressure block 8 is adapted to the limiting protrusion 51 around the main reducer housing 5, which can strengthen the fixation of the main reducer housing 5.

[0031] Preferably, the upper surfaces of the base plate 1 and the support plate 3 are on the same horizontal plane.

[0032] The upper surfaces of the base plate 1 and the support plate 3 together support the main reducer housing 5.

[0033] Preferably, the slider 2 is symmetrically provided with side plates 9 that are adapted to the base plate 1.

[0034] The side plate 9 slides with the bottom plate 1, which serves as a limiting mechanism.

[0035] Preferably, a strip groove 10 is provided on the base plate 1, and the bolt between the slider 2 and the base plate 1 is located in the strip groove 10.

[0036] The groove 10 facilitates the installation of bolts and nuts.

[0037] Preferably, the base plate 1 is a cross plate, and a positioning post 11 is provided on the cross plate. A positioning sleeve 12 is slidably installed on the positioning post 11, and the positioning sleeve 12 is adapted to the hole on the main reducer housing 5.

[0038] The cross plate can better support the main reducer housing 5, and the positioning pin 11 and positioning sleeve 12 work together to enhance the positioning of the main reducer housing 5.
