Description

Polishing clamp convenient for processing annular parts

Technical Field

The utility model relates to the technical field of polishing equipment, in particular to a polishing clamp convenient for processing annular parts.

Background

Polishing refers to a processing method for reducing the roughness of the surface of a workpiece by using mechanical, chemical or electrochemical actions to obtain a bright and flat surface, and is to modify the surface of the workpiece by using a polishing tool and abrasive particles or other polishing media. In the polishing process of hardware, it is often necessary to use auxiliary fixtures to fix the product to prevent the product from moving. For annular parts, such as nuts, when the outer surface of the annular part is polished, the part is mostly pressed on a worktable surface through a clamp, but the clamping of the existing clamp is not stable, and the part is easy to deviate during polishing, so that the processing quality is affected.

Disclosure of Invention

In order to overcome the defects, the utility model aims to provide a polishing clamp convenient for processing annular parts, which realizes effective clamping of the parts through mechanical cooperation, avoids movement of the parts in processing and ensures processing quality.

In order to achieve the above purposes, the utility model adopts the technical scheme that: a polishing clamp convenient for processing annular parts comprises a through hole arranged on a workbench, wherein a pressing piece hook component capable of moving up and down penetrates through the through hole, and the pressing piece hook component comprises a pair of pressing piece hooks capable of opening and closing to press or loosen the parts. The casting die hook comprises a rod body penetrating through the through hole, and a hook portion is integrally arranged at the top end of the rod body. When the pressing piece hook is closed, the hook part can freely pass through the inner hole of the part, and when the pressing piece hook is opened, the hook part can be pressed on the upper end surface of the part.

In the initial state, the pressing piece hook is closed, so that the inner hole of the part penetrates through the hook part and is placed on the workbench; opening the pressing piece hook to open the pair of hook parts, wherein at the moment, the side wall of the rod body can be attached to the inner hole of the part; then the pressing part hook is driven to move downwards, the side wall of the rod body moves downwards along the inner hole of the part, and the hook part moves downwards and presses against the upper end face of the part to clamp the part.

The utility model has the beneficial effects that: when the casting die hook is opened, the inner hole of the part is limited through the pair of rod bodies, the upper end face of the part is limited through the hook part, and therefore stable clamping of the part is achieved, movement of the part in the machining process is avoided, and machining quality is guaranteed.

Further, one is provided with the draw runner on the body of rod perpendicularly, and another is equipped with the confession on the body of rod the spout that the draw runner removed, still the cover is equipped with the spring that is located between two bodies of rod on the draw runner. Two ends of the spring are fixedly connected with the pair of rod bodies respectively. The sliding strips and the sliding grooves are arranged to realize the approaching or separating of the pair of rod bodies; through the setting of spring firstly when the draw runner just begins to remove to the spout, arbitrary pole physical stamina moves to laminating on the fenestrate lateral wall under the resilience force effect of spring, and then realizes spacing to this body of rod, secondly when casting die hook is opened, when two body of rods kept away from each other promptly, can drive the draw runner and remove to the direction of keeping away from the spout through the resilience force of spring.

Further, when the spring is in a compressed state, the pressing member hook is in a closed state. When the spring is in a natural state, the pressing piece hook is in an open state, and one end of the sliding strip extends into the sliding groove. Stretch into the spout with the one end of draw runner in making the draw runner can the part be located the spout all the time, and then take the body of rod of draw runner to carry out spacing in vertical direction, be convenient for follow-up two synchronous reciprocating of the body of rod.

Further, a shank of one of the compression member hooks extends downwardly and forms a hand-held end.

Furthermore, a limiting part used for inhibiting the pressing part hook from moving up and down is further arranged in the through hole, the limiting part comprises a pair of caulking grooves symmetrically formed in the through hole along the horizontal direction, and each caulking groove is internally provided with a positioning ball capable of being embedded into the pressing part hook.

Furthermore, both sides of the rod body of one pressing piece hook are provided with an upper arc-shaped groove and a lower arc-shaped groove which are arranged along the vertical direction, and the positioning beads can be embedded into the upper arc-shaped groove or the lower arc-shaped groove. The limit of the up-and-down movement of the rod body is realized through the matching of the positioning beads and the upper arc-shaped groove or the lower arc-shaped groove.

When the positioning beads are positioned in the lower arc-shaped groove, any rod body is pushed, the hook portion is closed to allow the part to penetrate, and then the rod body is loosened to open the hook portion; the handheld end of drop-down, because of the spacing of draw runner in the spout, two bodies of rod can move down in step, until the location pearl imbeds in the last arc wall, and at this moment, hook portion can press on the part, realizes the centre gripping to the part.

Furthermore, the hook part is also provided with an inclined surface which is convenient for the penetration of parts.
