A kind of automobile gearbox selector fork cubing
Technical field
The present invention relates to a kind of automobile gearbox selector fork cubings, belong to automobile detection field.
Background technique
Automobile speed-changing box pulling fork is essential part in automobile manufacture, and manufacture dimensional accuracy will have a direct impact on use
It is excessive that gap is not installed and occurred after installing to effect and service life or selector fork, but upper without a kind of cubing at present
Gearbox shifting shift fork is detected, in consideration of it, a kind of automobile gearbox selector fork cubing is to be badly in need of in the industry.
Summary of the invention
The present invention provides a kind of automobile gearbox selector fork cubing, and technical solution is selector fork cubing, it is the bottom of by
Seat, plane monitoring-network pin, thread measurement, positioning pin II composition, wherein pedestal is connected by screw to plane monitoring-network pin, passes through rotation
360 ° of plane monitoring-network pin are connected by screw to detect part flatness and thickness deviation value, thread measurement with pedestal, and part is put
Screw-thread detection pin is screwed in part after to cubing, is high-precision between thread measurement and pedestal to detect the position degree of threaded hole
Position positioning is spent, is connected by screw to, is positioned between positioning pin II and pedestal for clearance fit, and be connected by screw to, by
In just can guarantee the position degree relationship between each component by high accuracy positioning, cubing itself precision could be ensured.
The present invention solves gearbox shifting shift fork and solves shift fork working position thickness before transmission assembly installation
Blocked up excessively thin, screw thread and shift fork aperture position degree equidimension precision problem, avoid occurring after installing transmission assembly by
The appearance for phenomena such as beating tooth caused by abnormal sound, gap are too small when the gearbox shifting caused by gap is excessive, and also to driving
Safety brings guarantee.
The advantage of the invention is that structure is simple, and it is easy to operate, it is solid durable, it is at low cost.

Specific embodiment
1. refering to fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of automobile gearbox selector fork cubing of present embodiment, skill
Art scheme is selector fork cubing, it is made of pedestal 1, plane monitoring-network pin 2, thread measurement 3, positioning pin II 4, wherein pedestal 1
It is connected by screw to plane monitoring-network pin 2, part flatness and thickness deviation value is detected by 360 ° of rotational plane test pin,
Thread measurement 3 is connected by screw to pedestal 1, and part screws in screw-thread detection pin 3.2 in part after being put into cubing, to detect spiral shell
The position degree of pit is positioned for high precision position between thread measurement 3 and pedestal 1, is connected by screw to, positioning pin II 4 and bottom
It positions, and is connected by screw to for clearance fit between seat 1, due to just can guarantee between each component by high accuracy positioning
Position degree relationship could ensure cubing itself precision.
2. referring to Fig.2, pedestal 1 is made of mounting plate 1.1, washer 1.2, handle 1.3, indsole mounting plate 1.1 and washer
1.2 are bolted, and mounting plate 1.1 is bolted with handle 1.3, and handle 1.3 behaviour such as puts, moves convenient for cubing
Make.
3. plane monitoring-network pin 2 is made of Measuring plate 2.1, logical shotpin 2.2, positioning pin I 2.3, complete between three refering to Fig. 3
Portion is high-precision gap cooperation, to guarantee detection accuracy, leads to shotpin 2.2 with after the assembly of positioning pin I 2.3, is inserted into Measuring plate 2.1,
Being rotated by 360 ° again can detect whether the size of part plane and planar thickness is overproof.
4. refering to figure, 4, thread measurement 3 is made of support 3.1, screw-thread detection pin 3.2, guide sleeve 3.3, wherein support 3.1 with
Guide sleeve 3.3 is by being welded to connect, and screw-thread detection pin 3.2 and 3.3 concentricity of guide sleeve cooperate, and screw-thread detection pin 3.2 is before putting part
It pulls out, avoids interference with.
5. positioning pin II 4 and 1.1 clearance fit of mounting plate position refering to Fig. 5, it is connected by screw to, simultaneously using tool steel
And quench, it ensure that the intensity and hardness of positioning pin.
