[0034] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0035] This embodiment provides a fixture positioning mechanism, including a workbench 1 and a limiting plate 7 fixedly mounted on a frame. An mounting plate 11 is fixedly mounted on the workbench 1, and a cylinder 12 is fixedly mounted on the mounting plate 11. A fixing plate 2 is slidably mounted on the workbench 1. Fixing blocks 3 are fixedly mounted at both ends of one side of the fixing plate 2. A connecting plate 4 is fixedly mounted on one side of the fixing block 3. A fixture 5 is fixedly mounted on the upper end of one side of the connecting plate 4. The fixture 5 is used to clamp a workpiece 8, and a positioning plate 6 is fixedly connected to one side of the fixture 5. The positioning plate 6 is fixedly mounted on the top of the fixing block 3.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, guide rails 13 are symmetrically fixed on the workbench 1, sliders 21 are symmetrically fixed on the bottom of the fixed plate 2, the sliders 21 are slidably mounted on the guide rails 13, and positioning pins 22 are symmetrically fixed on one side of the fixed plate 2.

[0037] like Figure 2 and Figure 3 As shown, the fixing block 3 is L-shaped, the positioning pin 22 passes through the fixing block 3, the inner wall of the fixing block 3 is tightly fitted with the outer wall of the fixing plate 2, which can increase the contact area between the fixing block 3 and the fixing plate 2, and a screw hole 31 is provided through the fixing block 3. A bolt 32 is installed in the screw hole 31. A through hole is provided on the fixing plate 2. One end of the bolt 32 is threadedly connected to the screw hole 31 and the through hole in sequence, thereby fixing the fixing block 3 on the fixing plate 2.

[0038] like Figure 4 and Figure 5 As shown, a plurality of support plates 41 are fixedly provided on one side of the connecting plate 4, and side plates 42 are also fixedly provided at both ends of the connecting plate 4 on this side. The length of the side plates 42 is greater than the length of the support plates 41. One end of the positioning pin 22 passes through the connecting plate 4 and the side plates 42. Therefore, the fixing block 3 is provided between the fixing plate 2 and the connecting plate 4. In order to prevent the connecting plate 4 from detaching from the positioning pin 22, one end of the positioning pin 22 is threaded, and a nut is threadedly installed at its threaded end, thereby fixing the connecting plate 4 on one side of the fixing plate 2.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, a number of insert blocks 43 are fixedly provided on the other side of the connecting plate 4, and a number of grooves 14 are provided on one side of the workbench 1, and the insert blocks 43 are slidably installed in the grooves 14.

[0040] like Figure 6 and Figure 7 As shown, several sets of clamping plates 51 are symmetrically fixed on the hanger 5. Each set of clamping plates 51 is symmetrically fixed to one end with an arc-shaped plate 52. The workpiece 8 is snapped between two arc-shaped plates 52. The arc-shaped structure of the arc-shaped plate 52 can better fit the outer surface of the workpiece 8, increase the contact area with the workpiece 8, and thus improve the stability of clamping. Moreover, the inner wall of the arc-shaped plate 52 is made of elastic material, which has good elasticity and flexibility. When it comes into contact with the workpiece 8, it can undergo a certain elastic deformation, thereby closely fitting the surface of the workpiece 8. This not only enhances the clamping effect, but also, due to the characteristics of the elastic material, it will not cause wear to the surface of the workpiece 8.

[0041] like Figure 1 , Figure 2As shown, when installing the hanger 5, the hanger 5 is inserted between the connecting plate 4 and the side plate 42, and the positioning pin 22 also penetrates the hanger 5, further restricting the horizontal movement of the hanger 5 and ensuring that the position of the hanger 5 between the connecting plate 4 and the side plate 42 is accurate. The cooperation between the positioning pin 22, the connecting plate 4, the side plate 42, and the hanger 5 forms an integral connection structure, enhancing the integrity and stability of the hanger 5 installation structure. Furthermore, the lower surface of the hanger 5 is tightly fitted with the upper surface of the support plate 41, and the support plate 41 can withstand the weight of the hanger 5 itself and the gravity generated after the hanger 5 clamps the workpiece 8, thereby ensuring the initial stability of the hanger 5 installation structure.

[0042] like Figure 1 As shown, the upper end of the clamping plate 51 is fixedly connected to the side wall of the positioning plate 6, which enhances the structural strength and stability of the hanger 5 itself. The positioning plate 6 is fixedly connected to the fixing block 3 by screws, which further connects the hanger 5 with other parts of the entire mechanism. This ensures the structural stability of the positioning plate 6 and the hanger 5 from different angles and levels, so that the hanger 5 can always stay in the correct position during the operation of the mechanism.

[0043] like Figure 6 and Figure 7 As shown, the positioning plate 6 has several slots 61 through one side, and the processed parts 8 are located in each slot 61. Each processed part 8 has an independent positioning space.

[0044] like Figure 1 and Figure 8 As shown, the limiting plate 7 has a plurality of limiting grooves 71, and the positions of the limiting grooves 71 and the slots 61 correspond one-to-one.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, a fixed shaft 24 is fixedly installed at the center of one side of the fixed plate 2, and the output shaft of the cylinder 12 is fixedly connected to the center of the fixed shaft 24. Therefore, by driving the output shaft of the cylinder 12 to extend, the fixed plate 2 is driven to move along the guide rail 13 towards the limiting plate 7, thereby driving the fixed block 3 to move, and then pushing the connecting plate 4 and the hanging device 5 installed on it to move. During this process, the insert block 43 gradually slides out from the groove 14. As the hanging device 5 moves, one end of the workpiece 8 will gradually enter the limiting groove 71 on the limiting plate 7. The limiting groove 71 plays the final positioning role for the workpiece 8. It can accurately limit the position of the workpiece 8 and ensure that the workpiece 8 is in the correct position during the processing, thereby realizing the positioning and clamping of the workpiece 8.

[0046] In practical use, the fixing block 3 is fixed to the fixing plate 2 by bolts 32. The hanger 5 is inserted between the connecting plate 4 and the side plate 42, with the lower surface of the hanger 5 tightly fitted to the upper surface of the support plate 41. Then, the connecting plate 4 is set on one side of the fixing block 3 by positioning pins 22, and the insert 43 is inserted into the groove 14. A nut is threaded onto one end of the positioning pin 22 to fix the connecting plate 4. The positioning plate 6 is fixedly connected to the fixing block 3 by screws. The workpiece 8 is placed between the clamping plates 51 on the hanger 5, so that the workpiece 8 is clamped onto the two arc-shaped plates. Between 52; then drive cylinder 12, the output shaft of cylinder 12 extends, driving the fixed plate 2 to move along the guide rail 13 towards the limiting plate 7. The movement of the fixed plate 2 drives the fixed block 3 to move, which in turn pushes the connecting plate 4 and the hanging device 5 set on it to move. During this process, the insert block 43 gradually slides out from the groove 14. As the hanging device 5 moves, one end of the workpiece 8 will gradually enter the limiting groove 71 on the limiting plate 7. The limiting groove 71 plays the final positioning role for the workpiece 8, accurately limiting the position of the workpiece 8, ensuring that the workpiece 8 is in the correct position during the processing, and realizing the positioning and clamping of the workpiece 8.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
