Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a quarter arc grinder fixture. Background Art

[0002] In modern manufacturing, the precision and complexity of mold parts are increasing day by day. Arc features, as common geometric elements, play a key role in various mold designs. Such parts require not only high surface finish but also strict geometric tolerances, which is crucial to ensure the accuracy of the mold and the quality of the final product.

[0003] In order to meet today's high-efficiency and high-precision production needs, computer numerical control (CNC) processing technology is introduced. CNC processing controls the movement of machine tools through preset computer programs, and can realize complex shape processing in three-dimensional space under multi-axis linkage, including precise arc contour processing.

[0004] However, while CNC machining can achieve precise machining, it is also accompanied by high initial investment costs, maintenance costs, and requirements for operator skill levels. Especially for mold parts containing arcs, CNC machining often requires the use of specific arc interpolation instructions (such as G02, G03), combined with precise tool path planning and high-speed, high-precision machine tool motion control to ensure smooth transition and dimensional accuracy of the arc surface. Utility Model Content

[0005] The utility model aims to provide a quarter arc grinder fixture to solve the problem of high cost of using CNC to process the arc on mold parts.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A quarter arc grinder fixture comprises: a base and a clamping assembly arranged in the middle of the base;

[0008] The clamping assembly comprises a rotating handle rotatably connected to the base, a rotating circular disk connected to the end of the rotating handle and a part clamping member arranged at the end of the rotating circular disk. A rotating limit switch is arranged between the end surface of the base and the rotating circular disk.

[0009] Furthermore, the part clamping member comprises a fixing plate fixed on the rotating circular disk and a boss arranged on the fixing plate, wherein a clamping cavity is provided in the boss.

[0010] Furthermore, a locking block movably connected to one side of the boss is provided in the clamping cavity, and the locking block and the side wall of the clamping cavity form a part locking cavity.

[0011] Furthermore, an installation groove is formed on the end surface of the boss, and two sides of the fixing plate are inserted into the installation groove.

[0012] Furthermore, a silicone plate is movably provided on the inner wall of the clamping cavity to increase the clamping friction force.

[0013] Furthermore, a locking bolt is connected to the bottom of the locking block, and the locking bolt extends to the outside of the boss.

[0014] Furthermore, a rolling bearing is provided between the base and the rotating handle.

[0015] The utility model has the following beneficial effects:

[0016] The design of the rotating roundness disk of the utility model ensures the stability of the parts during rotation, reduces vibration during processing, and helps to improve the finish and roundness accuracy of the processed surface. The setting of the rotation limit switch can effectively control the rotation angle to ensure the consistency and repeatability of each processing. The configuration of the rotating handle allows the operator to easily adjust the position of the parts, and can quickly clamp and remove the parts without complex tools, thereby improving work efficiency. At the same time, the use of the locking bolt makes the locking process simpler and faster. The operator only needs to adjust the locking bolt to achieve a firm fixation of the parts.

[0017] At the same time, the design of the boss and the clamping cavity, combined with the movable locking block, can adapt to parts of different sizes and shapes, achieving flexible and reliable clamping. The introduction of the silicone plate increases the friction of the clamping surface, which can keep the parts stable even at high speeds, reduce slippage, and further improve processing safety. The setting of the rolling bearing reduces the friction between the base and the rotating handle, extending the service life of the equipment, while also reducing the operating resistance and making the rotation smoother. The design of the mounting grooves on both sides of the fixing plate enhances the stability of the overall structure, is easy to assemble and disassemble, and is convenient for daily maintenance and cleaning.

DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solution of the utility model in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1-2 This embodiment discloses a quarter arc grinder fixture, which includes: a base 1 and a clamping assembly 2 arranged in the middle of the base 1; the base 1 is used as a support platform for the entire fixture and is made of high-strength material to ensure stability. One end of the base 1 is connected to a rotating handle 21 through a rolling bearing 11. The design of the rolling bearing 11 reduces friction during the rotation process, improves the smoothness of operation and service life.

[0023] The clamping assembly 2 includes a rotating handle 21 rotatably connected to the base 1, a rotating circular disk 22 connected to the end of the rotating handle 21, and a part clamp 3 arranged at the end of the rotating circular disk 22. A rotating limit switch 23 is arranged between the end surface of the base 1 and the rotating circular disk 22. The rotating handle 21 is installed on the base 1, and can rotate freely and control the rotation of the rotating circular disk 22. The rotating circular disk 22 is firmly connected to the end of the rotating handle 21, and its surface is precisely processed to ensure stability and roundness during rotation, which is particularly important for the processing of parts that require precise angle control.

[0024] The part clamp 3 includes a fixed plate 31 fixed on the rotating circular disk 22 and a boss 32 arranged on the fixed plate 31, and a clamping cavity 33 is opened in the boss 32. A rotation limit switch 23 is arranged between the end face of the base 1 and the rotating circular disk 22. This limit switch can preset the rotation range. When the rotating handle reaches a quarter arc position each time, it automatically stops to prevent damage to the workpiece or wrong positioning caused by excessive rotation. The fixed plate 31 is inserted into both sides of the boss 32 through the installation groove 221 to achieve a stable assembly. A movable locking block 36 is arranged inside the clamping cavity 33 opened on the end face of the boss 32. The locking block 36 clamps the external workpiece through the locking bolt 37, which enhances the flexibility and adaptability of the clamping.

[0025] A locking block 36 movably connected to one side of the boss 32 is provided in the clamping cavity 33 , and the locking block 36 and the side wall of the clamping cavity 33 form a part locking cavity 34 .

[0026] In order to improve the stability of clamping, a silicone plate 35 is provided on the inner wall of the clamping cavity 33. The silicone plate 35 has good elasticity and friction coefficient, and can effectively increase the friction force during clamping without damaging the surface of the workpiece, and can maintain the stable position of the workpiece even at high speed.

[0027] Operation process: When in use, first place the part to be processed in the clamping cavity 33 of the boss 32, and rotate the rotating handle 21 to drive the rotating circular disk 22 and the part to rotate together. Adjust the rotating handle 21 to a predetermined position according to the processing requirements, and drive the locking block 36 to accurately lock the part through the locking bolt 37. During the processing, the rotating limit switch 23 rotates a quarter of an arc each time to perform arc processing.

[0028] The quarter arc grinder fixture provided in this embodiment not only simplifies the operation process and improves work efficiency, but also takes into account the convenience and safety of use while ensuring the processing accuracy. This fixture is particularly suitable for high-precision grinding of circular or arc-shaped workpieces, and is an important technological innovation in the field of precision machining.
