[0027] Please see Figures 1-3One embodiment of this utility model provides a side-pressure type quick positioning fixture based on angle adaptive adjustment, including a base plate 1, an angle-adjustable side-pressure component 2 for clamping parts adjustablely disposed on the base plate 1, and a positioning component 3 disposed on the base plate 1 for positioning the part 12. The positioning component 3 positions the part 12, and the angle-adjustable side-pressure component 2 presses the part 12. The side-pressure angle can be adjusted by adjusting the angle-adjustable side-pressure component 2, and the angle-adjustable side-pressure component 2 is adjustablely disposed on the base plate 1 to adapt to parts 12 of different sizes. It has high operational flexibility and a simple and practical structure.

[0028] like Figures 1-3 As shown, the angle adjustment side pressure assembly 2 includes an adjustment support plate 201 detachably mounted on the base plate 1, an adjustment handle operably mounted on the adjustment support plate 201, and a side pressure mechanism detachably mounted on the adjustment support plate 201. The adjustment handle is detachably connected to the base plate 1. Specifically, the side pressure mechanism includes a clamping support plate 205 detachably mounted on the adjustment support plate 201, a clamping handle 206 rotatably mounted on the clamping support plate 205, a clamping sleeve 207 mounted on the side of the clamping support plate 205 facing the part 12, a push shaft 208 movably mounted on the clamping sleeve 207, and a bending rod 2. 09. A housing 210 is disposed on the end of the clamping sleeve 207 opposite to the clamping support plate 205. A side pressure block 211 is movably disposed on the housing 210. One end of the bent rod 209 is rotatably connected to the clamping handle 206, and the other end of the bent rod 209 is rotatably connected to the clamping shaft. When the operator operates the clamping handle 206, the action of the bent rod 209 drives the push shaft 208 to move within the clamping sleeve 207, thereby pushing the side pressure block 211 to move within the housing 210. This pushes the side pressure block 211 to clamp the edges of the part 12, preventing the part 12 from moving during processing. The operation is convenient and the processing efficiency is improved.

[0029] Furthermore, the side pressure surface of the side pressure block 211 is made of rubber or polyurethane to prevent damage to the surface of the part 12.

[0030] like Figures 1-3 As shown, the adjusting handle includes a fastener 202 detachably inserted into the angle adjusting groove 2051, a clamping boss 203 fixedly disposed on the outside of the fastener 202, and a handle sleeve 204 sleeved on the clamping boss 203. By rotating the clamping support plate 205, the angle of the clamping support plate 205 can be adjusted due to the action of the angle adjusting groove 2051. After adjusting to a suitable angle, tighten the fastener 202, and the clamping boss 203 will press the clamping boss 203 to fix the clamping support plate 205. After processing is completed, rotate the handle sleeve 204 to loosen the fastener 202 and adjust the position of the clamping support plate 205.

[0031] like Figures 1-3 As shown, the housing 210 has a reset mechanism on at least one side.

One end of the spring 5 is connected to the first connecting pin 4, and the other end of the spring 5 is connected to the second connecting pin 6. Specifically, the reset mechanism is located on the upper and lower sides of the housing 210. The push shaft 208 can be connected to or not connected to the side pressure block 211. When the push shaft 208 is not connected to the side pressure block 211, when the push shaft 208 moves away from the side pressure block 211, the spring 5 pulls the side pressure block 211 to reset. The structure is simple and reasonable, and there is no need to manually reset the side pressure block 211, which improves processing efficiency.

[0032] like Figures 1-3 As shown, the side pressure block 211 has a V-shaped side pressure groove 2111 that runs vertically through the part 12 on the side facing the part 12. It has a high degree of matching with the edges and corners of the part 12 and a better pressing effect.

[0033] like Figures 1-3 As shown, the clamping support plate 205 is L-shaped, and the bottom plate of the clamping support plate 205 is provided with an angle adjustment groove 2051 that runs vertically through it. The angle adjustment groove 2051 is an arc ring. Furthermore, the angle range of the angle adjustment groove 2051 is 0°-90°. Generally, most parts are cuboids, but some irregular parts 12 have a protruding edge. The fixture of this utility model can be applied to such irregular parts 12 and has high versatility.

[0034] like Figures 1-3 As shown, the vertical plate of the pressing support plate 205 is provided with a vertical adjustment groove 2052 that passes through it in a direction perpendicular to it, so as to facilitate the adjustment of the height of the side pressing mechanism.

[0035] like Figures 1-3 As shown, the positioning component 3 includes a first positioning block 301 detachably disposed on the substrate 1 for positioning one side of the part 12, and a second positioning block 302 detachably disposed on the substrate 1 for positioning the other side of the part 12. The first positioning block 301 is perpendicular to the second positioning block 302. The first positioning block 301 is used to position one side of the part 12 in the length direction, and the second positioning block 302 is used to position one side of the part 12 in the width direction. The first positioning block 301 and the second positioning block 302 are elongated.

[0036] like Figures 1-3 As shown, a connecting plate 8 is provided below the substrate 1, and a support column 7 is detachably provided on the lower side of the substrate 1. The support column 7 is detachably connected to the connecting plate 8. The connecting plate 8 is also provided with a plurality of linear array connecting holes 801, which can adjust the position of the substrate 1 on the connecting plate 8. The connecting plate 8 is stably installed on the working platform, which will not be described in detail.

[0037] like Figures 1-3 As shown, the base plate 1 is provided with a horizontal adjustment groove 101 that runs vertically through it. The bottom plate of the pressing support plate 205 is detachably fitted with a pin 9, which passes through the horizontal adjustment groove 101. The lower end of the fastener 202 passes through the horizontal adjustment groove 101, and the lower end of the fastener 202 is fitted with a limiting plate 11. The lower end of the pin 9 passes through the limiting plate 11, and the lower end of the pin 9 is detachably fitted with a retaining spring 10. In this way, the fastener 202 will not slide arbitrarily. When it is necessary to move the pressing support plate 205, the pin 9 and the fastener 202 can be loosened, which makes it easy for the pressing support plate 205 to adjust its position according to the size of the part 12.

[0038] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
