Description

Technical Field

[0001] This utility model relates to the field of special clamp structure design, specifically a shaft-connected grinding tooth clamp. Background Technology

[0002] In the external cylindrical grinding and turning processes of machine parts, they are generally positioned and clamped through their central inner hole. However, for some parts, the diameter of the central inner hole used for positioning is too small; typical part structures are visible. Figure 7 This makes it difficult for ordinary clamps to hold the product, and also results in poor clamping rigidity, which in turn leads to a failure to guarantee product accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a shaft connecting gear grinding fixture, including a fixture body, a support base, a pressure plate and a clamping bolt;

[0004] The clamp is bowl-shaped and consists of a support block and a connecting block. The support block is a truncated shell shape with a larger top and a smaller bottom. The lower side of the support block is fixedly connected to the connecting block, which is an annular shape.

[0005] The clamp is fixedly installed on the support base by bolts.

[0006] As a preferred technical solution of this utility model, the pressure plate is annular and has multiple through holes, and the support block also has threaded holes that correspond to the number and position of the through holes.

[0007] As a preferred technical solution of this utility model, a flat key is fixedly connected to the upper side of the support base, and a keyway corresponding to the flat key on the upper side of the clamping body is opened at the lower end of the connecting block, so that the two cooperate with each other.

[0008] As a preferred technical solution of this utility model, the bottom end of the support base is provided with multiple U-shaped grooves.

[0009] As a preferred embodiment of this utility model, a positioning hole is provided in the middle of the clamping body, and the diameter of the positioning hole is equal to the diameter of the central shaft of the product to be processed.

[0010] The beneficial effects of this utility model are as follows: First, by cooperating with the pressure plate and the clamping body, this utility model clamps the product to be processed in the vertical direction, which can greatly improve the rigidity and stability of the positioning and clamping of parts, thereby achieving the goal of improving product accuracy.

[0011] Second, the structure and manufacturing process of this utility model are simple, and it has wide applicability and practical value. This fixture structure can be used for gear shafts with short axial dimensions and similar structural parts that require grinding of the outer circle, and it has strong universality.

[0021] The embodiments of this utility model are described in detail below.

[0022] See Figures 1-6 The shaft is connected to the grinding gear clamp, which includes a clamp body 1, a support base 2, a pressure plate 3, and a clamping bolt 4. The clamp body 1 is bowl-shaped and consists of a support block 11 and a connecting block 12. The support block 11 is a platform-shaped structure that is larger at the top and smaller at the bottom. The lower side of the support block 11 is fixedly connected to the connecting block 12, which is annular. The clamp body 1 is fixedly installed on the support base 2 by bolts.

[0023] This utility model has a simple structure and manufacturing process, and has wide applicability and practical value. It can be used for gear shafts with short axial dimensions and similar structural parts that require grinding of the outer diameter, and has strong versatility.

[0024] See Figures 1-6The pressure plate 3 is annular and has multiple through holes. The support block 11 also has threaded holes of the same number and position. A flat key 21 is fixedly connected to the upper side of the support base 2. The lower end of the connecting block 12 has a keyway corresponding to the flat key on the upper side of the clamping body 1, and the two cooperate with each other. Multiple U-shaped grooves are opened at the bottom end of the support base 2. A positioning hole 13 is opened in the middle of the clamping body 1. The diameter of the positioning hole 13 is equal to the diameter of the central shaft of the product to be processed.

[0025] It should be noted that the diameter of the positioning hole 13 and the central shaft of the product to be processed are in clearance fit.

[0026] This utility model uses the cooperation of the pressure plate 3 and the clamping body 1 to clamp the product to be processed in the vertical direction, which can greatly improve the rigidity and stability of the positioning and clamping of parts, and achieve the goal of improving product accuracy.

[0027] Specifically, first, insert the central shaft of the product into the positioning hole 13 on the fixture body 1 of this utility model, while the end face of the product contacts the support block 11. Then, place the pressure plate 3 on the product to be processed and align the through hole on the pressure plate 3 with the threaded hole on the support block 11. Then, press the pressure plate 3 tightly onto the product to be processed by the clamping bolt 4. Then, fix this utility model on the bearing table of the machine tool through the U-shaped groove on the support seat 2. Finally, the center of the machine tool will further press the part to be processed to complete the positioning.

[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the protection scope of the present invention.
