Firstly, the scroll processing jig according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3 , which can be used in a wide range of application scenarios for processing scroll parts.

As shown in FIGS. 1-2 , the scroll processing jig of the embodiment of the present invention includes a jig body 1 , which is used to clamp a scroll 2 and has a fixing assembly 3 and a driver 5 .

Specifically, as shown in Figures 1-2, the fixture body 1 includes at least three sets of fixing components 3. In this embodiment, there are six sets of fixing components 3, which are distributed around the fixture body 1, so it is used for more stable and accurate The fixed scroll 2, the driver 5 is arranged on the fixture body 1, the driver 5 is connected with the fixed assembly 3, and the driver 5 drives the fixed assembly 3 to act on the scroll 2.

Further, as shown in Figures 1-2, in this embodiment, the fixing assembly 3 includes: a clamping plate 31 and an elastic member 32, the clamping plate 31 is used to clamp the scroll 2, and the clamping of the clamping plate 31 The end is a V-shaped protrusion, and a V-shaped groove suitable for the V-shaped clamping end is adopted along the outer ring of the scroll 2, and the V-shaped protrusions of the six clamping pressure plates 31 are pressed into the V-shaped groove at the same time to realize scroll alignment. The compression of the turntable 2, the centering and the axial movement direction, the elastic member 32 has elasticity and is arc-shaped. One end is connected with the clamping pressure plate 31. When placing the scroll 2, open the clamping pressure plate 31, push the elastic member 32 to open, and then the elastic member 32 automatically shrinks inward, thereby driving the clamping pressure plate 31 to shrink inward, realizing the fixed scroll. Turntable 2, the elastic member 32 provides greater clamping force for the clamping plate 31, and the arc-shaped design of the elastic member 32 makes the elastic deformation space of the elastic member 32 larger, and the elastic deformation of one side can reach 1.2mm , so that the clamping plate 31 has a larger moving space, and can also realize the processing of the front and back sides of the scroll 2, because the fixed assembly 3 is processed at one time at the same time, so the opening and closing of the elastic member 32 has a great impact on the elastic member. 32 accuracy is not affected, and the accuracy within 0.01mm can be achieved.

Further, as shown in FIG. 3 , in this embodiment, a positioning component 4 is also included, and the positioning component 4 is arranged on the clamp body 1 for positioning the placement direction of the scroll 2 . The positioning assembly 4 includes: a sleeve 41, a positioning rod 42, a positioning ball head 43 and an adjustment member 44. The sleeve 41 is arranged on the fixture body 1, the positioning rod 42 is penetrated in the sleeve 41, and one end of the positioning rod 42 is provided with The positioning ball head 43, the positioning ball head 43 abuts the scroll 2, a conical hole adapted to the positioning ball head 43 is provided in a fixed direction on the outer ring of the scroll disk 2, and the other end of the positioning rod 42 is provided with an adjustment 44, the adjustment piece 44 can fix the positioning rod 42 in the casing 41, when the scroll 2 is placed on the fixture body 1, push the positioning rod 42, so that the positioning ball head 43 presses the cone on the scroll 2 hole, and fix the positioning rod 42 with the adjustment piece 44, the design of the positioning component 4 allows each scroll 2 to be placed in the same fixed direction, better processing the scroll 2, and higher precision .

Further, as shown in Figure 2, in this embodiment, the driver 5 is a piston cylinder, and the piston rod 51 of the piston cylinder drives the fixed assembly 3 to fix and loosen the scroll 2, and the piston rod 51 moves up and down. When the piston rod 51 moves upward, the elastic member 32 is pushed to expand, thereby opening the clamping plate 31 to expand outward; when the piston rod 51 moves downward, the elastic member 32 contracts inwardly, thereby the clamping platen 31 contracts inwardly, Clamp scroll 2 tightly.

The scroll 2 processing jig according to the embodiment of the present invention has been described above with reference to FIGS. 1 to 3 , which can realize a more stable and accurate fixed scroll 2 and high-precision machining of the front and back sides of the scroll 2 .

When using the scroll disk to process the fixture, the piston rod of the oil cylinder moves upward to push the elastic part to open, thereby opening the clamping plate to expand outward, manually placing the scroll disk parts, pushing the positioning rod, and pressing the positioning ball head to the scroll The conical hole on the disc is fixed by the adjustment piece, and then the piston rod moves downward, and the elastic piece shrinks inward, so that the clamping plate shrinks inward and clamps the scroll.
