Abstract
The utility model relates to a no impact frock of impressing of automatic transmission shift fork assembly book formula spring catch, including sleeve, fore-set, support and spacer pin, support one end fix on the sleeve, sleeve and fore-set threaded connection, fore-set stretch out telescopic depression bar portion and through the spacer pin of pin joint at the support other end on same axis, rectangular shape through-hole has been seted up to the axial of spacer pin, the pin passes the through-hole. Exert no impact power of impressing to the spring catch, and to the power of impressing of roll formula spring catch lasting and stable, do not produce the piece, do not have the destruction to roll formula spring catch, the success rate of impressing is high.
Description
Technical Field
The utility model relates to an automatic transmission shift fork assembly field, concretely relates to automatic transmission shift fork assembly roll formula spring catch's no impact frock of impressing.
Background
The automatic transmission shifting fork assembly plays a role in shifting gears in a transmission and is formed by connecting a fork shaft and a shifting fork through a rolled spring pin. The roll-type spring pin is in interference fit with holes on the fork shaft and the shifting fork.
The traditional assembly method is to align the hole position by eyes and then wedge the rolled spring pin by knocking a copper bar. The defect is that scraps are easy to generate, the cleanliness in the speed changer is damaged, the force for knocking the rolled spring pin by using a knocking method is not easy to control, and the rolled spring pin is easy to damage by knocking.
Disclosure of Invention
The utility model provides a frock of impressing is not strikeed to automatic transmission shift fork assembly book formula spring catch overcomes among the prior art book formula spring catch and is easily produced the piece after being strikeed, destroys the inside cleanliness of derailleur and strikes the high problem of a book formula spring catch rejection rate, and it turns into linear motion with the rotary motion of screw rod, and then applys no impact force of impressing to the spring catch, and the force of impressing to a book formula spring catch lasts and stable, does not produce the piece, does not have the destruction to a book formula spring catch, and the success rate of impressing is high.
The utility model discloses a concrete technical scheme as follows:
the utility model provides a no impact frock of impressing of automatic transmission shift fork assembly rolling pin, includes sleeve 1, fore-set 3, support 2 and spacer pin 5, 2 one end of support fix on sleeve 1, sleeve 1 and 3 threaded connection of fore-set, fore-set 3 stretches out telescopic depression bar portion 10 and is connected on same axis at the spacer pin 5 of the support other end through pin 6, rectangular shape through-hole has been seted up to spacer pin 5's axial, pin 6 passes the through-hole.
As a more excellent technical scheme of the utility model, support one end pass through 4 connections of first screw on support 2.
As a more preferable technical solution of the present invention, the inner diameter of the sleeve 1 is threaded, and the outer surface of the top post 3 is threaded with the sleeve 1.
As a more excellent technical scheme of the utility model, the support 2 on seted up the through-hole.
The beneficial effects are as follows:
the utility model discloses the no impact frock of impressing of shift fork assembly book round pin has utilized the rotary motion of screw thread to have converted linear motion's mode, adopts the spacing mode of spacer pin simultaneously, has effectively eliminated traditional dependence and has knocked the easy drawback that produces piece and easily harm the spring catch of assembly book formula spring catch. Put into the sleeve with a roll formula spring catch, rely on the rotary motion of screw to impel a roll formula spring catch and impress the assembly position, guarantee a roll formula spring catch and impress the appropriate position about spacing of spacer pin simultaneously, it is that the assembly quality of a roll formula spring catch obtains the guarantee.
Drawings
Fig. 1 is a schematic structural view of the impact-free press-in tool of the present invention;
FIG. 2 is a schematic view of a fork assembly;
wherein: 1. the novel spring pin comprises a sleeve, 2 parts of a support, 3 parts of a top column, 4 parts of screws, 5 parts of a limiting pin, 6 parts of a pin, 7 parts of a fork shaft, 8 parts of a shifting fork and 9 parts of a rolled spring pin.
Detailed Description
The invention is described in further detail with reference to the figures and the detailed description.
As shown in fig. 1, the utility model provides a no impact frock of impressing of automatic transmission shift fork assembly rolling pin, including sleeve 1, fore-set 3, support 2 and spacer pin 5, 2 one end of support fix on sleeve 1, 3 threaded connection on sleeve 1 and fore-set, fore-set 3 stretch out telescopic depression bar portion 10 and the spacer pin 5 of connecting at the support other end through pin 6 are on same axis, rectangular shape through-hole has been seted up to spacer pin 5's axial, pin 6 passes the through-hole.
In some embodiments, one end of the bracket is connected to the bracket through a second screw 4.
In some embodiments, the sleeve 1 is threaded on its inner diameter and the top post 3 is threaded on its outer surface to mate with the sleeve 1.
In some embodiments, the bracket is provided with a through hole. The weight of the whole tool is reduced.
The working process of the utility model is as follows:
between 3 and the sleeve 1 of fore-set pass through screw-thread fit, screw 4 is together fixed with support 2 and sleeve 1, and the spacing pin 5 is injectd in certain extent through interference fit's mode in the hole on pin 6 and the support 2. After fork shaft 7 and the alignment of fork 8, external screw thread screw in sleeve 1 on the fore-set 3, fore-set 3 stretches out telescopic depression bar portion 10 and exerts pressure to roll formula spring catch 9, roll formula spring catch 9 is impressed the shift fork pinhole, originally, spacer pin 5 at the shift fork pinhole is extruded gradually by roll formula spring catch 9, after spacer pin 5 is extruded a certain position, the axial motion of pin 6 restriction spacer pin 5, the axial motion of spacer pin 5 restriction roll formula spring catch simultaneously, then this moment, roll formula spring catch 9 has been impressed suitable position.
The present invention has been described in detail with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and the present invention can be implemented in various ways without modification, and the present invention is not limited by the above embodiments.
