Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge housing production technology, and in particular to a limiting mechanism for a bridge housing edge burr grinding equipment. Background Technology
[0002] The axle housing is the base for mounting the main reducer, differential, half-shafts, and wheel assemblies. Its main function is to support and protect these components. Generally, a standard non-disconnectable drive axle housing is a rigid hollow beam supported on the left and right drive wheels. The main reducer, differential, half-shafts, and other transmission components are housed within it. The housing is connected to the vehicle frame or cargo box via longitudinally mounted leaf springs. It is a crucial component of the drive axle and a major part of the running gear system. The drive axle housing should possess sufficient strength and rigidity, be lightweight, and facilitate the disassembly, assembly, and adjustment of the main reducer. Structurally, drive axle housings can be classified into three types: integral axle housings, separable axle housings, and composite axle housings.
[0003] In the existing technology, the production methods of bridge housing are divided into stamping and welding and casting. During the production process, the burrs on the bridge housing need to be ground to make the edges smooth, so as to facilitate subsequent processing. When grinding the burrs on the bridge housing, the bridge housing is usually restricted by using a bench vise to clamp the flat area of the bridge housing for fixation. This method is relatively cumbersome to install and requires multiple adjustments during clamping, making the limiting position inconvenient. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in the existing technology, the production methods of bridge housing are divided into stamping and welding and casting. In the production process, the burrs on the bridge housing need to be ground to make the edges smooth for subsequent processing. However, when grinding the burrs on the bridge housing, the bridge housing is usually restricted by using a bench vise to clamp the flat area of the bridge housing for fixation. This method is relatively cumbersome to install and requires multiple adjustments during clamping, and the limiting is inconvenient. Therefore, this utility model proposes a limiting mechanism for bridge housing burr grinding equipment.

A one-way hydraulic cylinder 11 is installed inside the expansion groove 21. An adjusting slider 7 is slidably connected inside the sliding grooves 15. Side sliders 16 are fixedly connected to both sides of the adjusting slider 7. 6 is slidably connected to the limiting side groove 6, and the side slider 16 is slidably connected to the output end of the one-way hydraulic cylinder 11. A spring 14 is fixedly connected between the output end of the one-way hydraulic cylinder 11 and the side slider 16. The upper end of the adjusting slider 7 has an inner cavity 17, and the lower end of the adjusting slider 7 is fixedly connected to a second connection port 18. The second connection port 18 communicates with the inner cavity 17. The upper end of the inner cavity 17 is fixedly connected to a second rubber ring 8. Both the second connection port 18 and the first connection port 9 are used to connect to the input end of the air pump.
[0023] The specific settings and functions of this embodiment are described below. By setting the end slot 2, the bridge housing to be ground is placed directly in the end slot 2, and the end slot 2 restricts the bridge housing. Then, by adjusting the slider 7 and the second rubber ring 8, the lower two sides of the bridge housing are attracted. Then, the one-way hydraulic cylinder 11 retracts, causing the spring to pull the adjusting slider 7 downward, thereby applying force to the bridge housing, increasing the connection strength between the bridge housing and the limiting frame 1, and ensuring connection stability. In this way, the limiting of the bridge housing is more convenient and faster, so as to facilitate the edge grinding of the bridge housing.
[0024] Example 2: Figure 1 - Figure 4As shown, the lower end of the expansion slot 21 has a slot 20, which engages with the lower end of the one-way hydraulic cylinder 11. The lower end of the slot 20 has a bottom groove 19, and a bottom limit plate 12 is fixedly connected inside the bottom groove 19. The lower end of the limit frame 1 has a mounting hole 10. The middle part of the end slot 2 has a recessed limit groove 3, and the lower end of the recessed limit groove 3 has a bottom suction groove 23. The lower end of the bottom suction groove 23 has a first through hole 24, and a third rubber is fixedly connected inside the bottom suction groove 23. Both sides of the inner concave limiting groove 3 of the ring 25 are fixedly connected to side limiting blocks 4. The upper end of the side limiting block 4 is fixedly connected to the end suction cavity 13. The end suction cavity 13 is fixedly connected to the first rubber ring 5. The lower end of the end suction cavity 13 is provided with a second through hole 26. The lower part of the middle of the limiting frame 1 is provided with a bottom through cavity 22. The first through hole 24 and the second through hole 26 are both connected to the bottom through cavity 22. The first connecting port 9 is fixedly connected to one side of the limiting frame 1. The first connecting port 9 is connected to the bottom through cavity 22.
[0025] The overall effect of this embodiment is that the end suction cavity 13 and the No. 3 rubber ring 25 are used to adsorb the arc area of the bridge housing, thereby further increasing the connection strength of the bridge housing and further ensuring the strength of use. The one-way hydraulic cylinder 11 is installed by means of snap-fit limiting through the setting of the slot 20, making the connection more convenient and easy to use.
[0026] The usage and working principle of this device are as follows: When in use, use bolts to install the limiting frame 1 on the grinding equipment, aligning with the mounting holes 10. Then, place the bridge housing in the end slot 2. The end suction chamber 13 and the bottom suction groove 23 draw in air, adsorbing and restricting the middle area of the bridge housing. Next, extend the top of the one-way hydraulic cylinder 11, and then manually push the adjusting slider 7 to make the second rubber ring 8 contact the surface of the bridge housing, adsorbing both sides of the bridge housing. Then, the one-way hydraulic cylinder 11 retracts, causing the adjusting slider 7 to apply force to the bridge housing, pressurizing it and ensuring a stable connection between the bridge housing and the limiting frame 1. Finally, the grinding equipment can remove any burrs from the edge of the bridge housing.
