DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a magnesium alloy gearbox fixture for garden tools.

[0035] Reference Figure 2A garden tool magnesium alloy gearbox fixture comprises a workbench 1, on which a rotary cylinder 2, a fixing portion 3 and an embedding portion 4 are provided. A pressure rod 21 is fixedly connected to one end of the output shaft of the rotary cylinder 2 away from the rotary cylinder 2, and the pressure rod 21 is used to clamp the workpiece. The rotary cylinder 2 drives the pressure rod 21 downward to firmly fix the workpiece on the fixture, thereby improving the clamping and fixing effect. A protective pad 22 for fitting with the workpiece is also fixedly provided on the pressure rod 21, and the protective pad 22 can be made of flexible materials such as rubber to protect the workpiece from damage or scratches caused by being pressed by the pressure rod 21. The provision of the protective pad 22 can effectively buffer the pressure of the pressure rod 21 on the workpiece, prevent the surface of the workpiece from being damaged or scratched, and protect the integrity and aesthetics of the workpiece. At the same time, the protective pad 22 can also increase the friction between the pressure rod 21 and the workpiece, further improving the clamping stability. The increase in frictional force enables the pressing rod 21 to press the workpiece more firmly, preventing the workpiece from sliding or deflecting during the machining process, thereby ensuring the stability and safety of the machining.

[0036] Reference Figure 2 and Figure 3 The fixing part 3 includes a moving seat 31 and two identical fixing columns 32. The fixing columns 32 are used to be inserted into the fixing holes 100 on the workpiece. The moving seat 31 is located above the workbench 1. The fixing columns 32 are fixedly connected to the side of the moving seat 31 away from the workbench 1. Through the cooperation of the moving seat 31 and the fixing columns 32, the workpiece is firmly fixed in the horizontal direction. The moving seat 31 is threadedly connected with a screw rod 311. The axis of the screw rod 311 is located between the two fixing columns 32. One end of the screw rod 311 is provided with a first driving member 312, such as a hand wheel and a motor. The screw rod 311 is rotatably connected to the workbench 1 along its own axis through a bearing. The screw rod 311 is driven to rotate by the first driving member 312, thereby driving the moving seat 31 to move along the axis direction of the screw rod 311, and then adjusting the position of the fixing column 32 to adapt to workpieces of different lengths. This structure enables the clamp to flexibly adapt to workpieces of different lengths, thereby improving the versatility of the clamp.

[0037] Reference Figure 3 and Figure 4, the fixed column 32 is threadedly connected with a first screw rod 321, the threads at both ends of the first screw rod 321 are in opposite directions, the first screw rod 321 is rotatably connected to the movable seat 31 along its own axis through a bearing, and one end of the first screw rod 321 is connected to a second driving member 322, such as another hand wheel or a motor. The first screw rod 321 is driven to rotate by the second driving member 322. Since the threads at both ends of the first screw rod 321 are in opposite directions, the distance between the two fixed columns 32 can be adjusted at the same time to adapt to workpieces of different widths. This design enables the clamp to be quickly adjusted according to the width of different workpieces, further improving the flexibility and ease of use of the clamp. At the same time, a support rod 323 is provided on the opposite side of the two fixed columns 32, and the support rod 323 abuts against the lower end of the workpiece to increase the stability of the workpiece in the vertical direction. A groove 325 for inserting the support rod 323 is provided on one side of the fixed column 32. The two fixed columns 32 move relative to each other, and the support rod 323 of one fixed column 32 slides in the groove 325 of the other fixed column 32 along the axial direction of the first screw rod 321 to adapt to workpieces of different thicknesses. This structure can ensure that the workpiece is stably supported in the vertical direction, prevent the workpiece from shaking or shifting during the processing, thereby improving the processing accuracy and product quality. In addition, the outer wall of the support rod 323 is also provided with a protective cover 324, which can be made of flexible materials such as rubber to protect the workpiece from direct contact with the support rod 323, thereby reducing scratches or damage. The design of this protective cover 324 can effectively protect the surface of the workpiece and ensure the integrity and aesthetics of the workpiece.

[0038] Reference Figure 2 and Figure 5 , the embedding part 4 includes two identical embedding columns 41, and the embedding column 41 is threadedly connected with a second screw rod 42, and the threads at both ends of the second screw rod 42 are also rotated in opposite directions. The second screw rod 42 is also rotatably connected to the workbench 1 along its own axis through a bearing, and one end of the second screw rod 42 is connected to a third driving member 43, such as another handwheel or motor. By rotating the third driving member 43, the second screw rod 42 can be driven to rotate, thereby adjusting the distance between the two embedding columns 41 to adapt to the position of the embedding hole 110 on the workpiece. This adjustment method can ensure that the embedding part 4 corresponds precisely to the embedding hole 110 on the workpiece, thereby improving the accuracy and efficiency of assembly. At the same time, the upper end surface of the embedding part 4 is also provided with a chamfer 411, so that the embedding hole 110 on the workpiece is aligned with the embedding part 4, thereby improving the assembly efficiency. The design of the chamfer 411 can guide the workpiece to be smoothly aligned with the embedding part 4, reduce the friction and resistance during the assembly process, and make the assembly smoother and more efficient.

[0039] The implementation principle of the tooling fixture for magnesium alloy gearbox of garden tools in the embodiment of the present application is as follows: by rotating the cylinder 2 to drive the pressure rod 21 to press down, the workpiece is fixed on the fixture, and the workpiece is firmly clamped; by adjusting the positions of the fixing part 3 and the embedded part 4, it can meet the clamping requirements of workpieces of different sizes, and improve the versatility and flexibility of the fixture; the setting of the protection pad 22 can protect the surface of the workpiece from damage, while increasing the friction force and improving the clamping stability. These designs work together to enable the fixture to achieve fast, accurate and firm clamping of the workpiece of magnesium alloy gearbox of garden tools, and improve the processing efficiency and processing quality.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
