Problems solved by technology

[0002] The bead ring is thin in thickness and large in size. If the bead ring is processed by a single piece, it is easy to cause deformation when clamping the bead ring. In addition, the inner and outer diameters of the car need to be clamped twice, resulting in poor concentricity. Low work efficiency and unstable dimensions

Embodiment Construction

[0013] Such as figure 1 , figure 2 and image 3 As shown, the fixture in this embodiment includes a chassis 1, a connecting block 2, a pressing block 3, two positioning pins 4 and two connecting bolts 5; .

[0014] The connection block 2 is concentric with the chassis 1 and the inner diameter of the connection block 2 is smaller than the inner diameter of the chassis 1 . A part of the connection block 2 is connected to the surface of the chassis 1 . Two threaded holes 2-1 and two positioning pin mounting holes 2-2 are set on another part of the connecting block 2 . The center line of the two threaded holes 2-1 passes through the center of the connection block 2, the center line of the two positioning pin mounting holes 2-2 passes through the center of the connection block 2, and the center line of the two threaded holes 2-1 The center line and the center line of the two positioning pin mounting holes 2-2 are perpendicular to each other.

Abstract

The invention discloses a clamp for machining inside diameters and outer diameters of fixed ball races. The clamp can simultaneously machine the inside diameters and the outer diameters of a pluralityof fixed ball races; and the processed fixed ball races have good concentricity, high processing work efficiency and stable processing size. An underpan, connecting blocks and a briquette of the clamp are all circular; the connecting blocks and the underpan are concentric; the inside diameters of the connecting blocks are smaller than the inside diameter of the underpan; a part of connecting blocks are connected with the pan surface of the underpan; the other part of connecting blocks are respectively provided with two or more screw holes and two or more positioning pin mounting holes; the briquette is provided with two or more bolt connecting holes and two or more positioning pin connecting holes; one end of each positioning pin is tightly matched and connected with a corresponding positioning pin mounting hole; and the other end of each positioning pin is arranged in the corresponding positioning pin connecting hole; and each connecting bolt penetrates through a corresponding bolt connecting hole and is in threaded connection with a corresponding thread hole.

Description

technical field [0001] The invention relates to an auxiliary tool for processing a bead ring, in particular to a fixture for turning the inner and outer diameters of a bead ring. Background technique [0002] The bead ring is thin in thickness and large in size. If the bead ring is processed by a single piece, it is easy to cause deformation when clamping the bead ring. In addition, the inner and outer diameters of the car need to be clamped twice, resulting in poor concentricity. The work efficiency is low, and the processed size is unstable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a jig for turning the inner and outer diameters of bead rings. Using this jig, the inner and outer diameters of multiple bead rings can be turned at the same time, and the processed bead rings are concentric The degree of precision is good, the processing efficiency is high, and the processing size is stable. [0004] The in...
