Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific embodiments.

[0018] Such as figure 1 , figure 2 , image 3 As shown, a dual-degree-of-freedom positioning pin includes a base 1, and also includes a positioning base 2 and a sliding base 3 mounted on the base 1. The base 1 is an "L" structure with two symmetrical openings on the vertical plane. A row of positioning holes; the positioning seat 2 is a square structure, including a threaded column 4 and a guide groove 5. There are two threaded columns 4, and the two are symmetrically fixed on one side of the positioning seat 2. The cross section of the guide groove 5 is inverted. The T"-shaped structure is located on the other side of the positioning base 2; the sliding base 3 is a "Z"-shaped structure, including a guide block 6, a vertical plate and a positioning pin 8; the shape of the guide block 6 and the shape of the guide groove 5 It is matched and fixed on the bottom of the vertical...

Abstract

The invention discloses a dual-freedom-degree locating pin, and belongs to the field of installation location parts. The dual-freedom-degree locating pin comprises a base, and further comprises a locating base and a sliding base which are installed on the base. The base is of an L-type structure. Two rows of locating holes are symmetrically formed in the vertical face of the base. The locating base is of a square structure. The locating base is provided with two threaded columns and a guide groove. The two threaded columns are symmetrically fixed on one lateral side of the locating base. The cross section of the guide groove is of a transverse T-type structure. The guide groove is formed in the other lateral side of the locating base. The sliding base is of a Z-type structure and comprises a guide block, a vertical plate and a locating pin body. The guide block is matched with the guide groove in shape and fixed at the bottom of the vertical plate. The dual-freedom-degree locating pin is simple in structural design, low in cost, small in occupied space, capable of suitable for locating and clamping plates with different hole diameters, short in manufacturing period and free of use of electrical devices such as an air cylinder.

Description

technical field [0001] The invention belongs to the field of mounting and positioning parts, and more specifically relates to a double-degree-of-freedom positioning pin. Background technique [0002] In the automobile welding equipment workshop, various positioning and clamping mechanisms are used on many welding fixtures. The commonly used positioning and clamping mechanisms are positioning pins and clamping blocks to position automobile sheet metal parts, and the cylinder is brought to the compression block and fixed Cooperate with the supporting block to realize the positioning and clamping function. However, this common structure takes up a lot of space, requires a large amount of design, and has many non-standard processed parts. The processing cost is high and the manufacturing cycle is long. In order to solve the above problems, a new type of positioning pin is designed to adapt to the positioning and clamping of plates with different apertures, the design cycle is r...
