Description

Technical Field

[0001] This utility model relates to the field of four-axis clamps for housings, and more specifically, to a four-axis clamp for the housing of an acceleration mechanism. Background Technology

[0002] In the field of mechanical manufacturing, the machining accuracy and efficiency of the accelerator mechanism housing are crucial to the overall performance of the equipment. The accelerator mechanism housing has a relatively complex structure, and clamping is required during machining. Existing accelerator mechanism housing fixtures have certain shortcomings. They struggle to accurately position and clamp both sides of the housing separately, resulting in mediocre clamping performance. During machining, workpiece loosening and positional shifts may occur, potentially affecting machining accuracy, reducing yield, lowering work efficiency, and even causing vibration and other issues that degrade the surface finish. Improving these issues has become a pressing problem for those skilled in the art. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a four-axis clamp for the housing of an acceleration mechanism, which aims to improve the existing clamps for the acceleration mechanism housing, which are difficult to accurately position and clamp the front and back sides of the housing separately, have a relatively poor clamping effect, and may cause the workpiece to loosen or shift during the processing, which may affect the processing accuracy, reduce the yield, reduce the work efficiency, and may also cause vibration and other phenomena, which reduce the quality of the processed surface.

[0004] This utility model is implemented as follows: a four-axis clamping fixture for an acceleration mechanism housing includes a base plate, a worktable is mounted on the upper end of the base plate, and a first workpiece clamping mechanism and a second workpiece clamping mechanism are mounted on the upper end of the worktable.

[0005] In a preferred embodiment of this utility model, the first workpiece clamping mechanism includes a hydraulic cylinder, which is mounted on the upper end of the worktable. A clamping block is hinged to the output end of the hydraulic cylinder, and a stabilizing block is mounted on the upper end of the hydraulic cylinder. A connecting plate is hinged to one side of the clamping block, and one side of the bottom end of the connecting plate is hinged to one side of the stabilizing block. A second hydraulic cylinder and a support rod are mounted on the upper end of the worktable. A pressing block is mounted on the output end of the second hydraulic cylinder, and a limit block is provided on the upper end of the support rod.

[0006] In the preferred embodiment of this utility model, multiple sets of hydraulic cylinders and support rods are provided. The upper end of the support rod is arc-shaped. When processing the back of the acceleration mechanism housing, the acceleration mechanism housing is placed on multiple sets of support rods. Multiple sets of limiting blocks are used to initially position the acceleration mechanism housing. The hydraulic cylinder drives the clamping block to move, so that the clamping block presses against the upper end of the acceleration mechanism housing, constraining and positioning the acceleration mechanism housing from the longitudinal Z-axis direction. The second hydraulic cylinder drives the abutment block to move, strengthening the clamping effect of the acceleration mechanism housing from the lateral direction. The acceleration mechanism housing is then processed in conjunction with a milling cutter. To enhance the supporting effect of the support rod, the upper end of the support rod is arc-shaped.

[0007] In a preferred embodiment of this utility model, a clearance groove is provided on the upper end of the worktable, a positioning block is installed inside the clearance groove, an installation rod is installed on the upper end of the worktable, a guide block is installed at one end of the installation rod, a guide groove is provided on one side of the guide block, a clamping rod is installed on the upper end of the worktable, a guide rod is installed at the upper end of the clamping rod, and the guide rod is arc-shaped. The clearance groove and the positioning block facilitate the placement of the acceleration mechanism housing body while enhancing the positioning effect of the acceleration mechanism housing body. The clamping rod enhances the clamping effect of the acceleration mechanism housing body. The guide groove and the guide rod guide the placement of the acceleration mechanism housing body.

A connecting block is mounted on the output end of the fourth hydraulic cylinder. The connecting block has a connecting port. The second positioning block has a connecting groove, and the second positioning block has a mounting groove that communicates with the connecting groove. The connecting port is located within the connecting groove and is connected to the mounting groove and the connecting port via a connecting pin. A gap exists between the connecting block and the connecting groove. A fifth hydraulic cylinder and a mounting bracket are mounted on the upper end of the worktable. A second connecting block is mounted on the output end of the fifth hydraulic cylinder. A mounting ear is mounted on one side of the mounting bracket, and the mounting ear has a groove. A spring is connected to the inner side of the groove. A third positioning block is connected to one side of the spring, and the spring and one end of the third positioning block are laterally connected. One end of the third positioning block is laterally connected to the... The second connecting block is connected, and the mounting ear and the third positioning block are provided with a connecting cavity and connected by a second connecting pin, so that the third positioning block can rotate through the second connecting pin. After the back side processing of the acceleration mechanism housing body is completed, the acceleration mechanism housing body is removed, flipped over and placed on the second support rod, where it is supported by the second limiting block. The second pressing block is driven by the third hydraulic cylinder to press the acceleration mechanism housing body from above. The connecting block and the second positioning block are moved by the fourth hydraulic cylinder, and the two ear holes of the acceleration mechanism housing body are simultaneously pressed and fixed. To avoid the occurrence of vibration, the connecting block... The gap between the second positioning block and the connecting groove allows the second positioning block to swing slightly, enabling it to fit more closely to the two ear plates of the accelerator mechanism housing, thus enhancing the clamping effect and reducing vibration. The fifth hydraulic cylinder drives the second connecting block to move, causing the third positioning block to rotate and position the accelerator mechanism housing. This allows the device to clamp and position both sides of the accelerator mechanism housing separately, achieving four-axis linkage machining. This enables machining of multiple surfaces during operation, improving machining accuracy and production efficiency, and effectively clamping and positioning accelerator mechanism housings with complex shapes.

[0009] In a preferred embodiment of this utility model, multiple sets of the third hydraulic cylinder and the second support rod are provided. The upper end of the second support rod is arc-shaped.

A third hydraulic cylinder drives a second clamping block to press the accelerator housing from above. A fourth hydraulic cylinder moves a connecting block and a second positioning block, simultaneously clamping and fixing the two ear plates of the accelerator housing. A fifth hydraulic cylinder moves the second connecting block, causing the third positioning block to rotate and position the accelerator housing. Finally, a milling cutter machine is used to machine the front side of the accelerator housing. This device, through the first and second workpiece clamping mechanisms, can clamp and position the front and back sides of a complex-shaped accelerator housing, and machine multiple surfaces. The clamping effect is good, reducing vibration during machining and enhancing the machining effect. Furthermore, it can machine two sets of workpieces simultaneously, improving work efficiency.
