Description

Technical Field

[0001] The utility model relates to the field of tooling fixtures, in particular to an edge grinding tooling fixture for wear-resistant steel castings. Background Art

[0002] Tooling is process equipment: it refers to the general term for various tools used in the manufacturing process. Fixtures are process devices used to quickly tighten the workpiece during processing to keep the machine tool, tool and workpiece in the correct relative position. Fixtures are indispensable components of mechanical processing. When clamping castings, existing tooling can generally only clamp one of the workpieces with cylindrical or rectangular cross-sections. If it is necessary to clamp workpieces of different shapes, the clamping head needs to be replaced to make the clamping head fit the outer wall surface of components with different cross-sectional shapes. Therefore, it is more cumbersome and inconvenient to use. For this reason, we propose a tooling fixture for grinding the edges of wear-resistant steel castings. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , a grinding fixture for wear-resistant steel castings, including a base 1, a protrusion 3 is integrally formed on the top of the base 1, and a slidable movable slide 4 is provided on the other side of the base 1, the movable slide 4 corresponds to the protrusion 3, and the movable slide 4 is mirrored on one side of the protrusion 3 and has two slidingly adjustable moving blocks 6. The ends of the two moving blocks 6 corresponding to each other are provided with an inclined surface 10, and the wall surface of the side of the moving block 6 corresponding to the protrusion 3 is flat. When it is necessary to clamp the casting, it is clamped according to the shape of the casting. When clamping a casting with a rectangular cross section, the casting is directly placed on the base 1 between the movable slide 4 and the protrusion 3. The position of the movable slide 4 is then adjusted so that the plane of the movable block 6 and the plane of the protrusion 3 fit the side of the casting to achieve clamping. When it is necessary to clamp a casting with a cylindrical cross-section, the spacing between the two movable blocks 6 is adjusted according to the diameter of the cylindrical casting so that the inclined surfaces 10 on the two movable blocks 6 fit the side of the casting. The position of the movable slide 4 is then adjusted so that the protrusion 3 also fits the side of the circular casting, thereby achieving three-point clamping. This device can not only clamp castings with cylindrical and rectangular cross-sections, but also can be adaptively adjusted according to the diameter of the cylindrical casting when clamping it, and is flexible to use.

[0022] Furthermore, a linear cylinder 2 is fixedly mounted on the base 1 , and the output shaft of the linear cylinder 2 is fixedly connected to the movable slide 4 . The linear cylinder 2 is activated to drive the movable slide 4 to move laterally, thereby achieving clamping.

[0023] Furthermore, a strip groove 12 is provided on the base 1 , and a movable supporting platform 11 is integrally formed at a position on the bottom of the movable slide 4 corresponding to the strip groove 12 , and the movable supporting platform 11 is slidably engaged in the interior of the strip groove 12 .

[0024] Furthermore, an inner wall groove 13 is opened on the inner wall of the side of the strip groove 12, and a strip protrusion 14 is integrally formed at the position of the movable supporting platform 11 corresponding to the inner wall groove 13. The strip protrusion 14 is adapted to the inner wall groove 13, and the strip protrusion 14 and the inner wall groove 13 are slidably connected together.

[0025] Furthermore, a rectangular groove 5 is provided on one side of the movable slide 4 corresponding to the protrusion 3, and a screw rod 7 is rotatably installed inside the rectangular groove 5. External threads are provided at both ends of the screw rod 7, and the external threads on both sides are mirror images. The movable block 6 is threadedly connected to the screw rod 7. One end of the screw rod 7 extends to the outside of the movable slide 4, and a knob is fixedly installed on the end of the screw rod 7 extending to the outside of the movable slide 4. When the screw rod 7 is rotated, the two movable blocks 6 will be displaced in different directions due to the different directions of the threads, thereby realizing the adjustment according to the diameter of the cylindrical casting when clamping it.

[0026] Furthermore, a side groove 8 is formed on the inner wall of the rectangular groove 5 , and a rectangular slider 9 is integrally formed on the position of the moving block 6 corresponding to the side groove 8 , and the rectangular slider 9 is slidably engaged with the side groove 8 .

[0027] Working principle: When it is necessary to clamp the casting, clamp it according to the shape of the casting. When clamping a casting with a rectangular cross-section, place the casting directly on the base 1 between the movable slide 4 and the protrusion 3, start the linear cylinder 2, and drive the movable slide 4 to move, and then adjust the position of the movable slide 4 so that the plane of the movable block 6 and the plane of the protrusion 3 fit the side of the casting to achieve clamping. When it is necessary to clamp a casting with a cylindrical cross-section, adjust the distance between the two movable blocks 6 according to the diameter of the cylindrical casting, and rotate the screw 7. At this time, due to the different thread directions, the two movable blocks 6 will be displaced in different directions, so that the inclined surfaces 10 on the two movable blocks 6 fit against the side of the casting, start the linear cylinder 2, and adjust the position of the movable slide 4. The movable slide 4 pushes gradually closer to the protrusion 3, so that the protrusion 3 also fits the side of the circular casting, thereby achieving three-point clamping.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
