Detailed Implementation

[0021] This utility model discloses a surface polishing device for die-cast parts. The following description, in conjunction with a preferred embodiment (Example 1), is shown in the accompanying drawings. Figures 1 to 9 The specific embodiments of this utility model will be further described below.

[0022] See attached diagram. Figures 1 to 9 , Figure 1 and Figure 2 The equipment for polishing the surface of die-cast parts from different perspectives is shown. Figures 3 to 6 The partial structures of the die-casting surface polishing equipment are shown respectively. Figure 7 The rack is shown. Figure 8 and Figure 9 The partial structure of the rack is shown separately.

[0023] Example 1.

[0024] Preferably, the die-casting surface polishing equipment includes a frame 100, wherein: The frame 100 includes a support frame 110, a workpiece positioning seat 120, and an adjusting frame 130. The support frame 110 has a support frame main body 111 and two support frame first positioning plates 112 and two support frame second positioning plates 113, which are integrally formed with the support frame main body 111. The workpiece positioning seat 120 is fixedly connected to the support frame main body 111. The adjusting frame 130 has an adjusting frame main body 131 and two adjusting frame second extensions 133 and two adjusting frame first extensions 132, which are integrally formed with the adjusting frame main body 131. The adjusting frame first extensions 132 are detachably connected to the support frame first positioning plates 112 and support frame second positioning plates 113, respectively. This makes the support frame 110 and the adjusting frame 130 detachably connected, and the distance between the adjusting frame 130 and the support frame 110 is adjustable. The frame 100 also includes a tension wheel positioning mechanism 140 and a driven wheel positioning mechanism 150. The tension wheel positioning mechanism 140 is fixedly connected to the second extension 133 of the adjusting frame, and the driven wheel positioning mechanism 150 is fixedly connected to the main body 131 of the adjusting frame. This allows the tension wheel positioning mechanism 140 and the driven wheel positioning mechanism 150 to be simultaneously distributed on the adjusting frame 130. When the distance between the adjusting frame 130 and the support frame 110 is manually adjusted, the tension wheel positioning mechanism 140 and the driven wheel positioning mechanism 150 distributed on the adjusting frame 130 can be adjusted synchronously. This allows the relative positions of the driven wheel 230 and the tension wheel 240 to be adjusted synchronously. This keeps the tension of the sanding belt 300 stable and the transmission accuracy consistent, which helps to shorten the adjustment time of the sanding belt 300.

[0025] The first positioning piece 112 of the support frame has a support frame positioning groove 114, and the adjustment frame 130 is provided with an adjustment frame fastener 134. The first extension 132 of the adjustment frame is detachably connected to the support frame positioning groove 114 of the first positioning piece 112 of the support frame through the adjustment frame fastener 134, so as to realize the detachable connection between the support frame 110 and the adjustment frame 130.

[0026] The support frame positioning groove 114 is arc-shaped so that the distance between the adjustment frame 130 and the support frame 110 can be adjusted.

[0027] The die-casting surface polishing equipment also includes a power system 200, which includes a motor 210. The frame 100 also includes a motor positioning seat 160, which is fixedly connected to the main body 131 of the adjustment frame. This allows the motor positioning seat 160 to also be distributed on the adjustment frame 130. When the distance between the adjustment frame 130 and the support frame 110 is manually adjusted, the motor positioning seats 160 distributed on the adjustment frame 130 can be adjusted synchronously. This allows the relative position of the motor 210 to be adjusted synchronously.

[0028] The power system 200 includes a drive wheel 220, a driven wheel 230, and a tension wheel 240. The die-casting surface polishing equipment also includes a sand belt 300. The drive wheel 220 is connected to the motor 210 for transmission. The driven wheel 230 is rotatably connected to the driven wheel positioning mechanism 150. The tension wheel 240 is rotatably connected to the tension wheel positioning mechanism 140. The sand belt 300 simultaneously wraps around the drive wheel 220, the driven wheel 230, and the tension wheel 240. This allows the motor 210 to drive the drive wheel 220, which in turn drives the driven wheel 230, the tension wheel 240, and the sand belt 300 to move. The sand belt 300 then polishes the workpiece that needs to be polished.

[0029] It is worth mentioning that the technical features such as the transmission relationship between the motor 210 and the drive wheel 220 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0030] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
