Abstract

The utility model discloses a detection device for an automotive gearshift fork, comprising a fixed base, wherein a location shaft and a fixed shaft are fixedly installed on the fixed base in parallel; a location disc is arranged on the location shaft; a limit groove clamped-connected with a semicircular shift head arranged on one end of the gearshift fork is arranged on the location disc; the fixed shaft is fixed with the other end of the gearshift fork; a pin shaft capable of sliding on a gear groove of the gearshift fork is arranged on the circumferential surface of the fixed shaft in a penetrating manner; and a rotary handle is further connected and arranged on the fixed shaft. The structure above is adopted, the end provided with the semicircular shift head of the gearshift fork is clamped-connected and fixed with the limit groove on the location disc, the other end of the gearshift fork is sleeved-connected and fixed on the fixed shaft, and the rotary handle is rotated, so that the pin shaft on the fixed shaft slides in the gear groove on the gearshift fork, thus realizing dynamic working detection on the gear groove on the gearshift fork.

Description

The pick-up unit of automobile-used gear shift fork

Technical field

The utility model relates to a kind of pick-up unit of automobile-used gear shift fork.

Background technology

Automobile-used gear shift fork is a kind of important component in the automobile variable speed operating-controlling mechanism; Described gear shift fork one end is semicircle shifting block; The other end is provided with the axis hole that socket-connects with declutch shift shaft, and a side end face of said axis hole is provided with irregular gear groove, and the opposite side end face of axis hole is the plane.Owing to whether the gear groove on the gear shift fork especially gear shift fork uses smooth and easy; With the gear shift operation that directly determines the user; And at present; Also be not specifically designed on the market and detect testing tool or the pick-up unit that gear shift fork especially detects gear groove on the gear shift fork, people just improve the surface smoothness of gear groove on the gear shift fork usually through the method for deburring or deburring, improve the fluency of user's gearshift with this.

Summary of the invention

To the deficiency of prior art, the utility model provides a kind of automobile-used gear shift fork pick-up unit that detects gear groove on the gear shift fork that is specifically designed to.

For realizing above-mentioned purpose; The utility model provides a kind of pick-up unit of automobile-used gear shift fork; Comprise firm banking, parallel locating shaft and the stationary shaft of being fixed with on the described firm banking, described locating shaft is provided with positioning disk; Positioning disk is provided with the semicircle shifting block that is provided with the gear shift fork one end stopper slot of clamping mutually; The other end of described stationary shaft and gear shift fork fixes, be equipped with on the periphery of stationary shaft one can slippage on the gear groove of gear shift fork bearing pin, also be connected with a rotary handle on the described stationary shaft.

The utility model can further be set to also include the hold down gag of the gear groove on the gear shift fork being pressed to the stationary shaft upper pin; Described hold down gag comprises separating support, lock shaft, clutch handle; Lock shaft and stationary shaft are the concentric setting, and the bearing pin on the said stationary shaft and lock shaft lay respectively at the both sides of gear shift fork, and described separating support is installed on the firm banking; Lock shaft is located on the separating support; One end of lock shaft is provided with the groove that socket-connects with stationary shaft, is fixed with clutch handle on the other end of lock shaft, and lock shaft is fixed with between this end and the separating support of clutch handle and is provided with holddown spring.

The beneficial effect of the utility model is: adopt said structure, at first gear shift fork is provided with this end of semicircle shifting block and connects and fixes mutually with stopper slot on the positioning disk, the shaft hole sleeve on the gear shift fork other end is connected on the stationary shaft again; And make bearing pin and the gear groove on the gear shift fork on the stationary shaft inconsistent; Make lock shaft under the effect of holddown spring through the clutch handle of controlling in the hold down gag then, the gear groove on the gear shift fork is pressed to the stationary shaft upper pin, at last through rotating rotary handle; Make the bearing pin slippage in the gear groove of gear shift fork on the stationary shaft; Realization detects the dynamic similation of gear groove on the gear shift fork, after detection finishes, draws back clutch handle; Gear groove on the gear shift fork is separated with bearing pin on the stationary shaft, conveniently take off gear shift fork from pick-up unit.
