However, the embodiments are not intended to limit the present invention. Example

[0031] Reference Figure 4 As shown, the wedge-shaped block internal positioning caliper fixture of this utility model includes several main parts: a base 1, a support block 2, a guide block 3, a workpiece support block 4, a connecting rod drive assembly 5, a wedge block 6, and a top block 7; the support block 2 is mounted on the base 1; the guide block 3 is mounted on the support block 2, and the guide block 3 is provided with a sliding groove 31; the workpiece support block 4 is mounted on the guide block 3, and the workpiece to be processed is placed on the workpiece support block 4; the connecting rod drive assembly 5 is mounted on the support block 2; the wedge block 6 is disposed in the sliding groove 31, the wedge block 6 is connected to the connecting rod drive assembly 5, and the connecting rod drive assembly 5 is used to drive the wedge block 6 to move within the sliding groove 31; the top block 7 is disposed in the guide block 3, and the top block 7 and the wedge block 6 are in contact through an inclined surface, and the connecting rod drive assembly 5 drives the wedge block 6 so that the top block 7 presses the workpiece to be processed against the workpiece support block 4.

[0032] Reference Figure 7 , 5 As shown, the end face of the wedge block 6 opposite to the top block 7 is set as a first inclined surface 61, and the end face of the top block 7 opposite to the wedge block 6 is set as a second inclined surface 71. The first inclined surface 61 and the second inclined surface 71 are in contact. One surface of the slide groove 31 is set as a plane, and the plane of the wedge block 6 is in contact with the plane of the inner wall of the slide groove 31. The connecting rod drive assembly 5 pushes the wedge block 6 to move linearly along the plane within the slide groove 31, thereby pushing the top block 7 to move.

[0033] In the above structure, the guide block 3 is provided with a guide groove 32, and the top block 7 is disposed in the guide groove 32, and the top block 7 can slide within the guide groove 32. The guide groove 32 is connected to the slide groove 31, and one end of the top block 7 with a second inclined surface 71 extends into the slide groove 31 and contacts the first inclined surface 61 of the wedge block 6. The cross-section of the guide groove 32 is "convex", and the cross-section of the mating top block 7 is also "convex". The lower end of the top block 7 is supported by the support block 2. The "convex" structure of the guide groove 32 and the top block 7 cooperates to prevent the top block 7 from coming out of the guide groove 32, so that the top block 7 can only move linearly within the guide groove 32.

[0034] Reference Figure 8 As shown, a return spring 33 is installed on the inner wall of the guide groove 32. The top block 7 is connected to the return spring 33, and the return spring 33 is used to provide an elastic restoring force for the top block 7 to return to its original position. Preferably, there are two return springs 33, which are symmetrically arranged so that the two return springs 33 provide a balanced elastic restoring force, so that the pushed-out top block 7 returns to its initial position under the force of the return spring 33.

[0035] Reference Figures 4-6 As shown, the workpiece support block 4 has a notch 41, which communicates with and faces the guide groove 32. One end of the top block 7 extending out of the guide groove 32 is connected to a protrusion 72, which is located inside the notch 41. The workpiece to be processed has a groove. The groove of the workpiece to be processed is placed on the workpiece support block 4. At this time, the protrusion 72 is also located in the groove of the workpiece to be processed. The top block 7 is driven to move outward of the guide groove 32 through the cooperation of the connecting rod drive assembly 5 and the wedge block 6, so that the protrusion 72 is pressed against the inner wall of the groove of the workpiece to be processed.

[0036] Reference Figure 1As shown, the linkage drive assembly 5 includes a power source 51, a first connecting rod 52, a second connecting rod 53, a first rotating shaft 54, and a second rotating shaft 55.

The first connecting rod 52 is hinged to one end of the first rotating shaft 54 ​​and the second connecting rod 53. The second connecting rod 53 is hinged to the guide block 3 via the second rotating shaft 55. The second connecting rod 53 is connected to the wedge block 6. The middle position of the second connecting rod 53 is hinged to the guide block 3 via the second rotating shaft 55. When the power source 51 drives the first connecting rod 52 to move, the second connecting rod 53 can rotate around the second rotating shaft 55. The rotation of the second connecting rod 53 pushes the wedge block 6 to move within the slide groove 31. Preferably, the power source 51 is a cylinder. The end of the second connecting rod 53 connected to the wedge block 6 is provided with a waist-shaped hole 531. A guide post 62 is connected to the wedge block 6 and is disposed within the waist-shaped hole 531. When the second link 53 can rotate around the second pivot 55, the guide post 62 can move within the waist-shaped hole 531 and change its relative position with the waist-shaped hole 531, thereby converting the swing of the second link 53 into the linear movement of the wedge block 6. Example

[0037] Based on the structure of Embodiment 1, and referring to Figure 2 , 2 As shown, a clamping assembly 8 is installed on the base 1. The clamping assembly 8 is used to clamp the workpiece to be processed onto the workpiece support block 4. The clamping assembly 8 includes a clamping power source 81 and a clamping head 82. The clamping power source 81 is installed on the base 1, and one end of the clamping head 82 is connected to the output end of the clamping power source 81. The clamping power source 81 drives the clamping head 82 to clamp onto the workpiece to be processed. A pad 821 is provided on the end face of the clamping head 82 that contacts the workpiece to be processed. When the clamping power source 81 drives the clamping head 82 to press the workpiece to be processed, the pad 821 contacts the workpiece to be processed. By setting the pad 821, damage to the surface of the workpiece to be processed can be prevented. Preferably, the clamping power source 81 is a cylinder.

[0038] Reference ​ As shown, a workpiece positioning block 9 is installed on the support block 2. The workpiece to be processed contacts the workpiece positioning block 9 to achieve workpiece positioning. When the workpiece to be processed is placed on the workpiece support block 4, one end of the workpiece to be processed abuts against the workpiece positioning block 9, thereby accurately locating the workpiece to be processed. Preferably, the end of the workpiece positioning block 9 that contacts the workpiece to be processed is set as an arc surface to avoid damage to the workpiece by the sharp corner of the workpiece positioning block 9.
