[0035] Example:

[0036] like Figures 1 to 5As shown, the utility model provides a wedge block clamping device, including a clamping base 1 and a wedge block clamping assembly 2, the wedge block clamping assembly 2 is arranged in the clamping base 1, and a side clamping plate 11 is provided on one side of the clamping base 1, and a clamping area for clamping a cavity part 3 is formed between the side clamping plate 11 and the wedge block clamping assembly 2, and the side clamping plate 11 is clamped on one side of the cavity part 3, and the wedge block clamping assembly 2 is clamped on the other side of the cavity part 3, and the bottom plate 12 of the clamping base 1 abuts against the bottom surface of the cavity part 3. In this embodiment, when clamping the cavity part 3, the side clamping plate 11, the bottom plate 12 and the wedge block clamping assembly 2 jointly achieve the clamping effect of the cavity part 3, which can effectively increase the contact area between the clamping device and the cavity part 3, improve the stability of the clamping, and avoid the deformation of the cavity part due to uneven force. At the same time, the wedge block clamping assembly 2 can apply a downward clamping force to the cavity part 3, thereby solving the problem of the part offset in the Z direction.

[0037] In this embodiment, the wedge block clamping assembly 2 preferably includes a movable end 21 and a fixed end 22. The fixed end 22 is fixed to the clamping base 1, and the movable end 21 is slidably connected to the fixed end 22. The connecting surface between the movable end 21 and the fixed end 22 is a wedge-shaped inclined surface, and the movable end 21 slides upward or downward along the wedge-shaped inclined surface. Specifically, when the movable end 21 slides downward along the wedge-shaped inclined surface, the movable end 21 approaches the cavity part 3 and clamps on the side of the cavity part 3. When the movable end 21 slides upward along the wedge-shaped inclined surface, the movable end 21 releases the clamping of the cavity part 3 and moves away from the cavity part 3. In this embodiment, the preferred driving structure of the movable end 21 is as follows: a second threaded hole 23 is provided on the connecting surface between the movable end 21 and the fixed end 22, and a top screw 24 is arranged in the second threaded hole 23; when the top screw 24 rotates in the second threaded hole 23, it can drive the movable end 21 to slide along the wedge-shaped inclined surface, and when the movable end 21 is effectively clamped on the surface of the cavity part 3, the top screw threaded hole structure can achieve a locking effect.

[0038] The base plate 12 of the clamping base 1 is provided with a guide groove 13, within which the fixed end 22 is disposed. In this embodiment, the fixed end 22 can slide along the guide direction of the guide groove 13 and, once in position, is secured to the base plate 12. This allows for highly precise and repeatable positioning, reduces positioning errors, and avoids uneven contraction of cavity components. Furthermore, it enables the clamping of various cavity components of varying sizes. Specifically, a threaded hole 14 is provided within the guide groove 13, within which a bolt 15 is disposed. The bolt 15 passes through the fixed end 22 and is secured with a nut 16, thereby securing the fixed end 22 after positioning. To accommodate the sliding movement of the fixed end 22 within the guide groove 13, a countersunk hole 25 is provided on the fixed end 22, pointing toward the cavity component 3. The bolt 15 can slide within the countersunk hole 25, and the nut 16 is tightened against the stepped surface of the countersunk hole 25.

[0039] In this embodiment, to ensure the stability of the clamping effect on the cavity part 3, a plurality of wedge-shaped block clamping assemblies 2 are provided on the clamping base 1, and the number of the wedge-shaped block clamping assemblies 2 is adapted to the length of the cavity part 3. Specifically, the plurality of wedge-shaped block clamping assemblies 2 are evenly spaced along the length of the cavity part 3, so that the force on the cavity part 3 is more uniform, and deformation of the cavity part 3 due to uneven force is avoided.

[0040] In order to prevent the side clamping plate 11 from being too high and affecting normal part processing, in this embodiment, it is necessary to ensure that the height of the side clamping plate 11 is less than the height of the processing surface of the cavity part 3.

[0041] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
