Abstract
The utility model discloses an universal hold -down mechanism, including clamp plate main part and compact heap, compact heap one end is the sphere, the other end is the plane, be provided with in the clamp plate main part with compact heap sphere matched with in the concave spherical surface, be provided with counter bore and the via hole that is used for mounting screws in the middle of the compact heap, also be provided with the through -hole that supplies the screw to pass in the clamp plate main part, the screw other end passes through lock nut and connects clamp plate main part and compact heap. The utility model discloses a this structure can reduce shift fork class part in the deformation of clamping in -process, improves the machining precision of part, promote the quality of part.
Description
Technical field
This utility model relates to a kind of pressing plate, is specifically related to a kind of universal hold-down mechanism.
Background technology
In the general course of processing, part, after location completes, need to use pressing plate to be compressed by part, in order to not to be shifted in the course of processing；At shift fork manufacture field, owing to part blank is as-cast condition, there is deformation or warpage situation in part, compressing point overlaps with anchor point to use common pressing plate to ensure, causing part in compaction process to there is deformation, processed rear part resilience, element precision cannot ensure.
Utility model content
In view of this, the purpose of this utility model is: solve the shift fork class part problem that thrust cannot overlap in machining tool clip process with anchor point.
For reaching above-mentioned purpose, this utility model following technical scheme of offer:
A kind of universal hold-down mechanism, including pressing plate main body and compact heap, described compact heap one end be sphere, the other end be plane, the interior concave spherical surface matched with compact heap sphere it is provided with in described pressing plate main body, the counterbore for installing screw and via it is provided with in the middle of described compact heap, being also equipped with the through hole passed for screw in described pressing plate main body, the described screw other end connects pressing plate main body and compact heap by locking nut.
Further, it is additionally provided with between described locking nut and pressing plate main body for ensureing that pressing plate main body and compact heap are in the compression spring of the state of being adjacent to all the time.
The beneficial effects of the utility model are: this utility model passes through this structure, can reduce the deformation in clamping process of the shift fork class part, improve the machining accuracy of part；Promote the quality of part.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, this utility model provides drawings described below to illustrate:
Fig. 1 is this utility model structural representation.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As shown in the figure, a kind of universal hold-down mechanism, a kind of universal hold-down mechanism, including pressing plate main body 4 and compact heap 5, described compact heap one end be sphere, the other end be plane, described pressing plate main body is provided with the interior concave spherical surface matched with compact heap sphere, in the middle of described compact heap, is provided with the counterbore for installing screw 3 and via, being also equipped with the through hole passed for screw 3 in described pressing plate main body, described screw 3 other end connects pressing plate main body and compact heap by locking nut 1.
In the present embodiment, it is additionally provided with between described locking nut and pressing plate main body for ensureing that pressing plate main body and compact heap are in the compression spring 2 of the state of being adjacent to all the time.
The universal hold-down mechanism of the present embodiment can reduce the deformation in clamping process of the shift fork class part, improves the machining accuracy of part；Promote the quality of part.
In the clamping process of the present embodiment, first compacted with workpiece of compact heap 5 plane one end contacts, by the automatic adjustment of sphere, it is ensured that compacted with part of whole plane contacts, then pressing plate main body begins through sphere centre, is applied on compact heap by active force.
Embodiment described above is only the preferred embodiment lifted by absolutely proving this utility model, and protection domain of the present utility model is not limited to this.The equivalent that those skilled in the art are made on the basis of this utility model substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
