Abstract
The utility model relates to a clamping mechanism. The clamping mechanism comprises an air cylinder, a push rod, two connecting rods, cams, clamping jaws and a protection cover. A piston rod of the air cylinder is connected with the push rod, the two sides of the push rod are symmetrically provided with cam grooves respectively, the two connecting rods are symmetrically installed on the two sides of the push rod, and the push rod is connected with the connecting rods through the cam grooves via the cams. The other end of each connecting rod is connected with one clamping jaw through a rotating shaft, and the clamping jaws can rotate around the rotating shafts. The middles of the clamping jaws are provided with protruding parts, and the inner sides of the front portions of the clamping jaws are of an arc-shaped structure. The protection cover is installed at the left ends of the two clamping jaws through the rotating shafts. The air cylinder pushes the push rod to drive the connecting rods to push forwards, the cams move along the cam grooves to enable the clamping jaws to rotate around the corresponding rotating shafts to be unfolded, a product is located between the two clamping jaws, and the air cylinder takes the clamping jaws back to clamp the product tightly.
Description
Technical field:
The utility model relates to clamping device apparatus field, relates in particular a kind of clamping device that adopts connecting rod cam mechanism driving jaw to clamp product.
Background technology:
On workshop or production line, often need gripping cylindrical component, now just use clamping device, the columniform clamping device complexity of clamping of prior art, complicated operation, two jaw poor synchronization, capturing product is easily to make a mess of product, has so also increased production cost.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of clamping device is provided, and adopts connecting rod cam structure, captures product by two jaw synchronous operations of air cylinder driven, and it is simple in structure, easy to use, and cost is low, practicality.
Technology solution of the present utility model is as follows:
A kind of clamping device, it comprises cylinder, push rod, connecting rod, cam, jaw and protective cover, the piston rod of described cylinder is connecting push rod, described push rod both sides are arranged with respectively a cam path, described connecting rod has two, two connecting rod symmetries are arranged on push rod both sides, and push rod and connecting rod are by cam path and utilize cam to link together; The other end of described each connecting rod is connected with a jaw by rotating shaft respectively, and jaw can rotate around the shaft; In the middle of described jaw, be provided with a protuberance, curved structure inside jaw front portion; Described protective cover is arranged on the left end of two jaws by rotating shaft.
As preferably, described protective cover is the frame structure of an end opening, and its push rod, connecting rod and cam lay respectively at protective cover inside.
As preferably, the arcuate structure place of inner side, described jaw front portion is provided with cushion rubber bumper.
The beneficial effects of the utility model are:
This structure of the utility model is to adopt bar linkage structure to adopt cylinder to complete the structure of clamping part, has saved cost, and succinct practicality has completed part holding action.
The utility model small volume, simple in structure, air cylinder driven when work, push rod is released, and drivening rod promotes forward, and cam moves along cam path, and gripper is made pivot point on protective cover, reaches cylinder release jaw and opens, and cylinder is regained jaw promptly.Thereby reach the crawl to part.
Brief description of the drawings:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model during not with protective cover.
Detailed description of the invention:
Embodiment, see attached Fig. 1 and 2, a kind of clamping device, it comprises cylinder 1, push rod 2, connecting rod 3, cam 4, jaw 5 and protective cover 6, the piston rod of described cylinder is connecting push rod, and described push rod both sides are arranged with respectively a cam path, and described connecting rod has two, two connecting rod symmetries are arranged on push rod both sides, and push rod and connecting rod are by cam path and utilize cam to link together; The other end of described each connecting rod is connected with a jaw by rotating shaft 7 respectively, and jaw can rotate around the shaft; In the middle of described jaw, be provided with a protuberance, curved structure inside jaw front portion, and arcuate structure place is provided with cushion rubber bumper, can protect like this product; Described protective cover is arranged on the left end of two jaws by rotating shaft, described protective cover is the frame structure of an end opening, and its push rod, connecting rod and cam lay respectively at protective cover inside, can prevent that foreign material from entering in cam path, ensures the smooth operation of clamping device.
The utility model course of work: cylinder is released push rod drivening rod and promoted forward, and cam moves along cam path, makes jaw rotate and open around the shaft, product 8 is between two jaws, and then cylinder is regained jaw and is firmly grasped product.
Above-described embodiment is the specific descriptions that the utility model is carried out; just the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, those skilled in the art according to the content of above-mentioned utility model make some nonessential improvement and adjust all fall into protection domain of the present utility model within.
