Referring to fig. 1-4, the embodiment of the present invention provides a high precision fixture assembly, which includes a workbench 1, a first station 2 and a second station 3 are disposed on the workbench 1, a first pressing structure 11 is disposed on the first station 2 and the second station 3, and a second pressing structure 12 is disposed between the first station 2 and the second station 3. The first pressing structure 11 comprises a first air cylinder 15 and a first pressing head 14, and a piston rod of the first air cylinder 15 penetrates through the workbench 1 and is fixedly connected with the first pressing head 14 above the workbench 1. The second pressing structure 12 includes a second cylinder 15 and a second pressing head 16, and a piston rod of the second cylinder 15 penetrates through the workbench 1 and is fixedly connected with the second pressing head 16 above the workbench 1. The second pressure head 16 comprises a fixing portion 20, a first pressing portion 4 and a second pressing portion 5, the fixing portion 20 is connected with a piston rod of the second air cylinder 15, the first pressing portion 4 and the second pressing portion 5 are located on two sides of the fixing portion 20 respectively, the first pressing portion 4 is close to the first station 2, the second pressing portion 5 is close to the second station 3, and the fixing portion 20 is in a shape that the direction from the second air cylinder 15 to the direction far away from the workbench 1 is bent.

The utility model discloses in the embodiment, whole fixed part 20 that is crooked shape can be on the piston rod to the slight beat of

first station

2 or 3 orientations of second station, and the plane of two products on first station 2 and the second station 3 of alignment guarantees that second compact structure 12 compresses tightly two products simultaneously, strengthens the fixed stability of product, avoids the phenomenon of product processing in-process shake sword.

Specifically, a plurality of first pressing structures 11 are respectively arranged on the first station 2 and the second station 3, each first pressing structure 11 is independent from each other, and each first pressing structure 11 can only press the product on the first station 2 or the product on the second station 3 independently. A second compacting means 12 between the first station 2 and the second station 3 is then used to compact the products in both stations simultaneously. Therefore, the products on the two stations can be kept stable, the number of the compression structures and the space required by the installation of the compression structures are reduced, the size of the workbench 1 is reduced, and the cost is reduced.

Fixed part 20 is to the crooked shape in workstation 1 top, and when first portion 4 and the unable in close contact with product of second portion 5 that compresses tightly, fixed part 20 has guaranteed two portions of compressing tightly and can and product surface in close contact with to two station direction beat to guarantee to compress tightly the effect.
