Technical Field

[0001] This utility model relates to the field of automotive leaf spring technology, specifically to a connecting and fixing device for automotive leaf spring assemblies. Background Technology

[0002] The automotive leaf spring assembly is an elastic element in the automotive suspension system. It typically consists of multiple springs, a design that gives the spring assembly high load-bearing capacity and good shock absorption performance. The automotive leaf spring assembly needs to be secured during connection and fixing.

[0003] Existing technologies, such as CN216030422U, describe an automotive leaf spring assembly clamping device. High-pressure oil in the hydraulic push rod is discharged into the hydraulic pump tank through an oil supply pipe, thereby causing the hydraulic push rod to descend. This allows the main and auxiliary leaf springs to fit more tightly before assembly, reducing the shaking of the main and auxiliary leaf springs after assembly and improving the safety of the vehicle during driving.

[0004] However, this device still has some shortcomings in its use:

[0005] 1. During the fixing process of the leaf spring, this device is limited to fixing the two sides of the spring and cannot fix the four sides completely. This may cause the position of the leaf spring to be unstable during the processing.

[0006] 2. The hydraulic push rod and pressure block of this device are in fixed positions, which is easy to adjust, but this also limits the flexibility in the processing, thereby reducing the convenience of operation and work efficiency. Utility Model Content

[0007] The purpose of this utility model is to provide a connecting and fixing device for automotive leaf spring assemblies, in order to solve the problem mentioned in the background art that, in the process of fixing leaf springs, the device is limited to fixing only the two sides of the spring and cannot fully fix the four sides. This leads to instability in the position of the leaf spring during processing. The hydraulic push rod and pressure block of this device are fixed in position and easy to adjust, but this also limits the flexibility in the processing, thereby reducing the convenience of operation and work efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A connecting and fixing device for automotive leaf spring assembly includes a processing platform, on the top of which a fixing component and a processing component are respectively provided, and the processing component is located on the side of the fixing component;

[0010] The fixing assembly includes a mounting platform fixedly connected to the top of the processing platform, a first fixing seat fixedly connected to the side of the mounting platform, a guide plate hinged to the side of the first fixing seat, an electric telescopic rod fixedly connected to the side of the guide plate, a second fixing seat hinged to the end of the electric telescopic rod, a fixing plate fixedly connected to the side of the second fixing seat, the side of the fixing plate being stepped, a sliding groove being provided on the top of the processing platform, and an auxiliary groove being provided on the side of the processing platform.

[0011] As a preferred embodiment of this utility model, the fixing component includes a mounting bracket on the top of the processing platform, the mounting bracket being located on the side of the mounting table, and a rectangular block being fixedly connected to the bottom of the mounting bracket, the rectangular block extending into the sliding groove and slidably connected to the sliding groove.

[0012] As a preferred embodiment of this utility model, the auxiliary groove is connected to the sliding groove, and a fixing rod is provided on the side of the processing platform. The fixing rod passes through the auxiliary groove and extends into the rectangular block, and the fixing rod is threadedly connected to the rectangular block.

[0013] As a preferred embodiment of this utility model, a hydraulic telescopic rod is fixedly connected to the top of the mounting frame, the telescopic part of the hydraulic telescopic rod passes through the mounting frame and is slidably connected to the mounting frame, and a pressure plate is fixedly connected to the end of the telescopic part of the hydraulic telescopic rod.

[0014] As a preferred embodiment of this utility model, a movable block is fixedly connected to the bottom of the fixed plate, and a movable groove is provided on the top of the mounting platform. The movable block extends into the movable groove and is slidably connected to the movable groove.

[0015] As a preferred embodiment of this utility model, the pressure plate is located directly above the mounting platform, and the outer surface of the pressure plate is provided with anti-slip texture.

[0016] As a preferred embodiment of this utility model, the bottom of the processing platform is fixedly connected to two support legs, and the two support legs are positioned opposite each other.

[0017] As a preferred embodiment of this utility model, four fixing plates are provided, with two opposite fixing plates having the same size.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by using a mounting platform, a first fixed seat, a guide plate, an electric telescopic rod, a second fixed seat, and a fixed plate in combination, the automotive leaf spring assembly can be fully fixed, avoiding the unstable position of the leaf spring during processing, and improving the accuracy and stability of processing. The mounting platform serves as the load-bearing foundation, and the guide plate and the electric telescopic rod are hinged between the first and second fixed seats. When it is necessary to fix the leaf spring, the extension or retraction of the electric telescopic rod drives the guide plate and the fixed plate to move, thereby achieving the clamping and fixing of the leaf spring. The operation is simple and quick, and the fixing effect is significant.

[0020] 2. In this utility model, the coordinated use of a mounting bracket, hydraulic telescopic rod, pressure plate, rectangular block, sliding groove, and fixing rod facilitates the position adjustment of the pressure plate and mounting bracket, enabling rapid pressing and fixing of the automotive leaf spring assembly. The hydraulic telescopic rod is mounted on the mounting bracket. When the leaf spring needs to be pressed, the extension of the hydraulic telescopic rod drives the pressure plate downward. The rectangular block slides within the sliding groove, facilitating the adjustment of the pressure block's position. The fixing rod secures the position of the rectangular block, achieving uniform pressing of the leaf spring. This design is convenient to operate, firmly fixed, and effectively improves the processing quality and production efficiency of the leaf spring. Attached Figure Description

[0029] Among its features, it can fully fix the automotive leaf spring assembly, avoiding the instability of the leaf spring position during processing and improving the accuracy and stability of processing.

[0030] In this embodiment, as Figure 1 and Figure 4As shown, the fixing component 2 includes a mounting bracket 301 on the top of the processing platform 1. The mounting bracket 301 is located on the side of the mounting table 201. A rectangular block 304 is fixedly connected to the bottom of the mounting bracket 301. The rectangular block 304 extends into the sliding groove 6 and is slidably connected to the sliding groove 6. An auxiliary groove 5 communicates with the sliding groove 6. A fixing rod 305 is provided on the side of the processing platform 1. The fixing rod 305 passes through the auxiliary groove 5 and extends into the rectangular block 304. The fixing rod 305 is threadedly connected to the rectangular block 304. A hydraulic telescopic rod 302 is fixedly connected to the top of the mounting bracket 301. The telescopic part of the hydraulic telescopic rod 302 passes through the mounting bracket 301 and is slidably connected to the mounting bracket 301.
