Description

Technical Field

[0001] This utility model relates to the field of leaf spring processing technology, and in particular to a fixture for processing the side of a leaf spring. Background Technology

[0002] A leaf spring, or simply leaf spring, is a leaf-shaped spring made up of at least one stacked leaf of spring steel. Leaf springs are commonly used in the suspension of wheeled vehicles. Originally called laminated or bracket springs, and sometimes referred to as semi-elliptical springs or cart springs, they are one of the oldest forms of springs, dating back to the Middle Ages.

[0003] Existing technologies for clamping leaf springs using conventional methods in manufacturing involve cumbersome operations, unreliable positioning, extremely low efficiency, and inconsistent product quality. To address these issues, patent application number 202020302711.5 discloses a fixture for facilitating the machining of the side of leaf springs. This fixture includes a base, a long pressure plate, a short pressure plate, and a positioning key. The fixture, through the combined action of the positioning key, the long pressure plate, and the short pressure plate, improves the leaf spring manufacturing process. This invention can be used in leaf spring manufacturing processes, improving production efficiency, and is simple in structure and safe and reliable.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: During use, because the pressure plate partially obstructs the leaf spring, after processing one part of the leaf spring, the pressure plate needs to be replaced to process the obstructed area. This process not only requires stopping the machine and manually replacing the pressure plate, but also complicates the installation and disassembly of the leaf spring because the pressure plate is fixed by clamping screws. This is not only time-consuming and labor-intensive, but also significantly reduces the processing efficiency of the leaf spring, leaving room for improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixture for machining the side of a leaf spring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixture for machining the side of a leaf spring includes a worktable, a clamping mechanism, and a leaf spring.

[0008] The workbench is equipped with a clamping mechanism and a leaf spring drilling machine. The leaf spring is mounted on the clamping mechanism, and the leaf spring drilling machine corresponds to the clamping mechanism and the leaf spring.

[0009] The clamping mechanism includes a bracket, a threaded rod one, a moving plate, a hydraulic cylinder, a support plate, a motor, a threaded rod two, a slider, and a stop block. The bottom of the worktable is equipped with a hydraulic cylinder, the output end of which passes through the worktable and is fixedly connected to the support plate. The leaf spring is set on the support plate. Through the cooperative design between the worktable and the clamping mechanism, not only can the leaf spring be automatically clamped and fixed, but the clamping position can also be automatically adjusted, improving convenience and processing efficiency.

[0010] Specifically, two supports are fixedly installed on the workbench. A threaded rod is rotatably connected to one of the supports. Multiple movable plates are threaded onto the threaded rod. All of the movable plates abut against the leaf spring. The leaf spring is moved by the support plate and interacts with the multiple movable plates, thereby achieving the effect of automatically clamping and fixing the leaf spring.

[0011] Specifically, each of the multiple movable plates has a stop block welded to its bottom, and each of the multiple stop blocks is in contact with the leaf spring. Each of the multiple movable plates has a threaded rod rotatably connected to it, and each of the multiple threaded rods has a slider threadedly connected to it. Each of the multiple sliders is in contact with the leaf spring. Through the cooperation between the threaded rods, sliders, and stop blocks, the leaf springs of different specifications can be limited, preventing them from moving during the processing of the leaf springs. This not only improves stability but also expands the applicability.

[0012] Specifically, an electric motor is fixedly installed on one of the two brackets. The output end of the electric motor is connected to one end of the threaded rod. By driving the hydraulic cylinder in the reverse direction, the limiting force on the leaf spring is released. The electric motor drives the threaded rod to rotate on the corresponding bracket and perform threaded transmission with the multiple moving plates, thereby causing the multiple moving plates to slide synchronously a certain distance and exposing the obstructed positions of the multiple moving plates.

[0013] Specifically, the multiple movable plates are slidably connected to the two brackets. A guide rod is fixedly installed on one of the two brackets. The multiple movable plates are slidably connected to the guide rod, and the connection is detachable. Each of the multiple movable plates has a sliding groove. The multiple sliders slide in the multiple sliding grooves respectively, which facilitates the stable sliding of the multiple movable plates and limits the movement of the multiple movable plates.

[0014] Specifically, the bottom of the workbench is provided with two support plates, and the two support plates are fixedly connected by the same horizontal plate. The hydraulic cylinder is fixedly installed on the horizontal plate for fixing the hydraulic cylinder, and the connection is detachable.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) A clamp for processing the side of a leaf spring according to the present invention, through the driving of the hydraulic cylinder, causes the support plate to move the leaf spring and act with multiple moving plates, thereby achieving the effect of automatically clamping and fixing the leaf spring, reducing manual labor and improving convenience and processing efficiency.

[0017] (2) The fixture for processing the side of a leaf spring according to this utility model can achieve the effect of automatically moving and adjusting the clamping position of the leaf spring through the cooperation between the hydraulic cylinder and the electric motor, which further improves the convenience and processing efficiency.

[0018] (3) The clamp for processing the side of the uniform leaf spring of this utility model can achieve the effect of limiting the leaf springs of different specifications through the cooperation between the threaded rod, the slider and the stop block, so as to avoid the leaf springs from moving during the processing. This not only improves the stability but also expands the scope of application and makes it more practical. Attached Figure Description

[0026] Reference Figure 1-4 A fixture for machining the side of a leaf spring includes a worktable 1, a clamping mechanism 2, and a leaf spring 3.

[0027] The workbench 1 is equipped with a clamping mechanism 2 and a leaf spring drilling processing device 6. The leaf spring 3 is mounted on the clamping mechanism 2. The leaf spring drilling processing device 6 corresponds to the clamping mechanism 2 and the leaf spring 3. The leaf spring drilling processing device 6 includes a robotic arm, a drill bit, a moving motor, and a lead screw. The workbench 1 is equipped with a slide rail, and the lead screw is installed inside the slide rail. One end of the slide rail is equipped with a moving motor, and the output end of the moving motor is connected to one end of the lead screw. The robotic arm is threadedly connected to the lead screw, and one end of the robotic arm is equipped with a drill bit. By driving the lead screw through the moving motor, the lead screw and the base of the robotic arm are threadedly transmitted, thereby achieving the effect of moving and adjusting the robotic arm. The cooperation between the robotic arm and the drill bit can achieve the effect of drilling the leaf spring 3. The leaf spring drilling processing device 6 is existing technology and will not be described in detail.

[0028] The clamping mechanism 2 includes a bracket 21, a threaded rod 22, a moving plate 23, a hydraulic cylinder 24, a support plate 25, a motor 26, a threaded rod 27, a slider 28, and a stop block 29. The bottom of the worktable 1 is equipped with a hydraulic cylinder 24. The output end of the hydraulic cylinder 24 passes through the worktable 1 and is fixedly connected to the support plate 25. The leaf spring 3 is set on the support plate 25. Through the cooperative design between the worktable 1 and the clamping mechanism 2, not only can the leaf spring 3 be automatically clamped and fixed, but the clamping position can also be automatically adjusted, which improves convenience and processing efficiency.

[0029] In this method, two supports 21 are fixedly installed on the workbench 1. One of the supports 21 is rotatably connected to a threaded rod 22. Multiple movable plates 23 are threadedly connected to the threaded rod 22. The multiple movable plates 23 all abut against the leaf spring 3. The leaf spring 3 is moved by the support plate 25 and acts with the multiple movable plates 23, thereby achieving the effect of automatically clamping and fixing the leaf spring 3.

[0030] In this method, multiple movable plates 23 are welded with stop blocks 29 at their bottoms, and multiple stop blocks 29 are in contact with the leaf spring 3. Multiple movable plates 23 are rotatably connected with threaded rods 27, and multiple threaded rods 27 are threaded with sliders 28, and multiple sliders 28 are in contact with the leaf spring 3. Through the cooperation between the threaded rods 27, sliders 28 and stop blocks 29, the leaf springs 3 of different specifications can be limited, preventing the leaf springs 3 from moving during processing. This not only improves stability but also expands the scope of application.

[0031] In this method, a motor 26 is fixedly installed on one of the two supports 21. The output end of the motor 26 is connected to one end of the threaded rod 22. By driving the hydraulic cylinder 24 in the reverse direction, the limiting position of the leaf spring 3 is released. The threaded rod 22 is rotated on the corresponding support 21 and performs threaded transmission with multiple moving plates 23 through the drive of the motor 26. This causes the multiple moving plates 23 to slide synchronously a certain distance, and exposes the blocking position of the multiple moving plates 23.

[0032] In this method, multiple movable plates 23 are slidably connected to two supports 21. One of the supports 21 is fixedly mounted with a guide rod 7. Multiple movable plates 23 are slidably connected to the guide rod 7, which is a detachable connection. Multiple movable plates 23 are provided with a sliding groove. Multiple sliders 28 slide in the multiple sliding grooves respectively, which facilitates the stable sliding of multiple movable plates 23 and limits the movement of multiple movable plates 23.

[0033] In this method, the bottom of the workbench 1 is provided with two support plates 4, and the same horizontal plate 5 is fixedly connected between the two support plates 4. The hydraulic cylinder 24 is fixedly installed on the horizontal plate 5 for fixing the hydraulic cylinder 24, and the connection is detachable.

[0034] Working principle: In use, firstly, the leaf spring 3 is placed on the support plate 25. Then, driven by the hydraulic cylinder 24, the support plate 25 moves the leaf spring 3 upward, so that the top of the leaf spring 3 contacts and connects with multiple moving plates 23. After that, the leaf spring 3 is adjusted again, so that one side of the leaf spring 3 contacts the stop block 29. Then, by rotating multiple threaded rods 27 in sequence, the threaded rods 27 and the slider 28 are threadedly driven, so that the slider 28 contacts the other side of the leaf spring 3. At this time, through the cooperation between the stop block 29 and the slider 28, the leaf spring 3 is limited, thereby preventing the leaf spring 3 from moving during the processing of the leaf spring 3 by the leaf spring drilling processing equipment 6. After that, the hydraulic cylinder 24 is started again, so that the support plate 25 and multiple moving plates 23 act, thereby achieving the effect of automatically clamping and fixing the leaf spring 3.

[0035] When multiple movable plates 23 are needed to cover the position for processing, the hydraulic cylinder 24 is first reversed to release the clamping limit on the leaf spring 3 and make the leaf spring 3 disengage from the movable plate 23. Then, the motor 26 is started, so that the output end of the motor 26 drives the threaded rod 22 to rotate on the corresponding bracket 21 and perform threaded transmission with the multiple movable plates 23, so that the multiple movable plates 23 slide synchronously a certain distance and expose the position covered by the multiple movable plates 23. Then, the hydraulic cylinder 24 is started, and the support plate 25 and the multiple movable plates 23 clamp and fix the leaf spring 3 again. Then, the leaf spring drilling processing equipment 6 is used to process the position covered by the leaf spring 3, thereby achieving the purpose of processing the leaf spring 3.

[0036] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the leaf spring 3 be automatically clamped and fixed, but the clamping position can also be automatically adjusted, improving convenience and processing efficiency. Moreover, the structure is simple and the practicality is higher.
