A kind of Pneumatic horizontal centering clamping device
This utility model relates to field of fixtures.
Can select the parallel folder of the biggest stroke on injection molding mechanical arm fixture as product need to be gripped the product that stroke ratio is bigger, this parallel folder is heavier, and cost is high, is easy to crush product simultaneously, the biggest to mechanical hand aging effects.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of Pneumatic horizontal centering clamping device.
This utility model is achieved by the following technical solution: a kind of Pneumatic horizontal centering clamping device, including base, described base both sides are provided with vertical installing plate, it is provided with guide post between two installing plates, on described guide post, interval sliding is provided with two chucks, two chucks are connected by a linkage, any one installing plate is provided with the cylinder for promoting chuck, described linkage includes bearing block, by ball bearing rotating support center swing seat on described bearing block, swing seat two ends, described center connect spaced two chucks respectively by connecting sheet and set bar.
In technique scheme, described guide post is provided with two, and two described guide posts be arranged in parallel.
In technique scheme, connected by cylinder connector between described chuck and described cylinder.
This utility model has the advantages that this utility model principle of device is simple, and versatility is very strong, low cost of manufacture, and two chucks can be regulated by regulation cylinder stroke folder to inside and outside moved distance thus can be to the clamping elasticity scalable of product.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings: see Fig. 1 to Fig. 4, a kind of Pneumatic horizontal centering clamping device, including base 1, described base 1 both sides are provided with vertical installing plate 2, it is provided with guide post 3 between two installing plates 2, and described guide post 3 is provided with two, and two described guide posts 3 be arranged in parallel.
On described guide post 3, interval sliding is provided with two chucks 4, and two chucks 4 are connected by a linkage 5, are provided with the cylinder 6 for promoting chuck 4 on any one installing plate 2, are connected by cylinder connector 8 between described chuck 4 and described cylinder 6.
Described linkage 5 includes bearing block 50, by ball bearing 51 rotating support center swing seat 52 on described bearing block 50, swing seat 52 two ends, described center connect spaced two chucks 4 respectively by connecting sheet 53 and set bar 54.
Promote while wherein an installing plate 2 moves by cylinder 6, this installing plate 2 promotes center swing seat 52 to rotate along bearing centre to swing by being connected to the connection sheet 53 of center swing seat 52 one end, and what now center swing seat 52 other end was arranged connect sheet 53 drives another installing plate 2 to move identical stroke to installing plate 2 rightabout promoted with cylinder.
