AI Technical Summary
Technical Problem
In the prior art, the external spline angle deviation detection tool of the double-head spline shaft leads to misjudgment, which increases production costs.
Method used
A double-headed spline angle deviation detector for outer spline shafts is designed, including a base plate, a first positioning plate, a second positioning plate and a feeler gauge. Through the design of the slide groove and the slide end, angle deviation within a certain range is allowed to avoid misjudgment.
Benefits of technology
The pass rate of double-head spline shafts is improved and production costs are reduced.

Abstract
The utility model provides an external spline angle deviation testing fixture for a double-end spline shaft, which relates to the technical field of detection tools and comprises a bottom plate, a first positioning plate, a second positioning plate and a filler gauge. The first positioning plate is fixed on the bottom plate; a sliding groove is formed in the bottom plate. The second positioning plate is detachably fixed on the bottom plate; when the second positioning plate is fixed on the bottom plate, the second positioning plate is fixed in the sliding chute in a sliding manner; a first inner spline hole is formed in the first positioning plate; a second inner spline hole is formed in the second positioning plate; the second inner spline hole and the first inner spline hole share the same hole axis; the second positioning plate comprises a sliding block end; the sliding block end is located in the sliding groove. When the sliding block end is attached to the inner wall of one side of the sliding groove, a gap space is reserved between the sliding block end and the inner wall of the other side of the sliding groove, and the feeler gauge can be inserted into the gap space in a clearance fit mode. The external spline angle deviation testing fixture of the double-end spline shaft provided by the utility model solves the problem of high production cost of the double-end spline shaft in the prior art, and can reduce the production cost of the double-end spline shaft.
