Background

At present, the rapid development of the electronic industry and the household appliance industry, the functional structures of products become complex and diversified, a plurality of parts need to be clamped through inner supports in the processes of processing, assembling and transporting, and a plurality of inner support clamping modes have some inevitable defects at present.

1. In the process of clamping a product through the inclined wedge mechanism, a Z-direction acting force of the product appears under the influence of an inclined wedge force of the inclined wedge mechanism in the Z direction, so that the Z-direction positioning of the product is inaccurate, and in the Z-direction positioning, an auxiliary clamping mechanism is required to be added to limit the Z-direction position or manually knock to enable the Z-direction to be tightly attached to a supporting surface. This mechanism adds virtually to the cost of the equipment and the labor time, and may also exhibit bounce behavior.

The side-push clamping mechanism is used, the repeated positioning precision of the product is inaccurate due to errors of the product positioning characteristics and clamping errors, and meanwhile, the side-push mechanism occupies too large space and is inconvenient to use for some small products.

When the product is clamped by the internal-supporting clamping jaw, the clamping jaw is always in line contact with the product due to the size error of the product, the product is easily clamped, and meanwhile, the clamping jaw can not absorb the positioning error of the product and can not be adjusted in the clamping process because the clamping jaw generates the clamping force under the action of the self elasticity of the clamping jaw material.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a cam internal stay clamping mechanism, includes the location main part, be equipped with a plurality of locating holes between the upper and lower wall of location main part, the bottom surface fixedly connected with limiting plate of location main part, the four corners department of locating hole all is equipped with the chucking through-hole, the locating hole internal rotation clamps has tight cam, and is a plurality of tight cam all rotates and runs through same limiting plate, the product model is equipped with to the chucking through-hole inside callipers, the top surface that presss from both sides tight cam is equipped with the cam clamping jaw.

Preferably, the position of the limiting plate corresponds to the positions of the positioning holes.

Preferably, the size of the clamping through hole is matched with that of the product model.

Preferably, the size of the positioning hole is matched with that of the clamping cam.

Preferably, the clamping cam has two rotational directions.

The utility model has the advantages that:

the utility model discloses the weak point that the clamping mechanism who constructs solves above-mentioned commonly used is fastening the product in-process and exists to get strong points and make up for the weak point and solve the clamping problem of product, improve the qualification rate of product.

1, the utility model discloses, solve the Z of product appearing at the tight in-process of clamp to removing the phenomenon, this mechanism makes the product receive the clamp force direction and begin to be in Z to perpendicular all the time through parallel rotation cam clamping mechanism, prevents that product Z from removing to.

2, the utility model discloses, solve the product and lead to repeated positioning accuracy to reach the requirement problem because of the positioning error reason at the clamping in-process, this mechanism can independently press from both sides the orientation of pressing from both sides tight product from taking every cam clamping jaw of cam auto-lock effect and can absorb product clamping error and guarantee that the zero clearance is pressed from both sides tightly.

3, the utility model discloses, solve the product and be pressed from both sides the phenomenon of hindering easily at the clamping in-process, this mechanism course of working is adjustable through smooth cambered surface contact product and clamp force, prevents effectively that the product from pressing from both sides the phenomenon of hindering.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, a cam internal stay clamping mechanism, including location main part 1, be equipped with a plurality of locating holes 6 between the upper and lower wall of location main part 1, the bottom surface fixedly connected with limiting plate 2 of location main part 1, the four corners department of locating hole 6 all is equipped with chucking through-

hole

7, 6 internal rotations of locating hole clamp have clamped tight cam 4, a plurality of tight cam 4 all rotate and run through same limiting plate 2, product model 3 is equipped with to the chucking through-hole 7 inside the card, the top surface of clamping cam 4 is equipped with cam clamping jaw 5, the position of limiting plate 2 corresponds with the position of a plurality of locating holes 6, chucking through-hole 7 and product model 3's size adaptation, locating hole 6 and the size adaptation of clamping cam 4, there are two the direction of rotation of clamping.

The working principle is as follows: the utility model discloses the mechanism utilizes the tight principle of many tight clamps of cam, and the independent contact of every cam clamping jaw presss from both sides a location characteristic of tight product, just so can absorb the product and the error of feeding ensures the repeated positioning accuracy of product clamping, and cam rotation presss from both sides tight back self and has self-locking effect to keep the clamp force stable production removal in-process not hard up, and the clamp force can also be adjusted according to rotation angle and prevent the phenomenon that the clamp of product hindered.
