Description
Technical field
The utility model relates to the two resilient key press-fitting tool of a kind of manual station gearbox shifting assembly, press-fiting, enhancing productivity for completing the two resilient key of gearbox shifting assembly.
Background technology
In gearbox shifting general assembly process, have a large amount of two resilient plunger needs to press-fit, this just needs the two resilient key of quick riveting in dress assembling.But, in prior art, can only be that first large resilient key 2/3 length of manual riveting one enters pin-and-hole, the less resilient key of riveting one enters large elasticity pin-and-hole, finally together two resilient key rivetings is entered pin-and-hole again.Operating process is very inconvenient, completes the station need of work time of about 5 minutes, and as easy as rolling off a logly occurs production accident.
Utility model content
The utility model is the weak point for avoiding existing for above-mentioned prior art, a kind of simple two resilient key press-fitting tool is fast provided, to enhance productivity, easily simple operations, reduce the work difficulty of operator, and job safety is guaranteed, reduce the generation of production accident.
The utility model is that technical solution problem adopts following technical scheme:
The two resilient key press-fitting tool of the utility model, its feature is: arrange one section of metal bar, Blind locating holes is provided with in described metal bar, described Blind locating holes is stepped hole, the bottom outlet section of described stepped hole is small finger setting section, the aperture Duan Wei great resilient key positioning section of described stepped hole, the length of described small finger setting section is less than the length of small pin, makes the small pin be positioned in small finger setting section protrude out in large resilient key positioning section; The length of described large resilient key positioning section is less than the length of large resilient key, the large resilient key be fitted in large resilient key positioning section is protruded out in front end and can be pressed into workpiece pin-and-hole to arrive at workpiece spindle pin-and-hole.
The two resilient key press-fitting tool of the utility model, its feature is also: on described large resilient key positioning section, be evenly provided with three resilient plunger radially, utilizes the large resilient key of described resilient plunger riveting, makes press-fiting in process and must not come off.
The two resilient key press-fitting tool of the utility model, its feature is also: described metal bar divides three sections of settings, is be segmentation position in the bottom surface, hole of stepped hole and the step place of stepped hole respectively.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, simple, easy to operate, the production efficiency of the utility model structure is greatly improved;
2, the utility model significantly reduces potential safety hazard.

Detailed description of the invention
See Fig. 1 and Fig. 2, in the present embodiment, the version of two resilient key press-fitting tool is: arrange one section of metal bar, Blind locating holes is provided with in metal bar, Blind locating holes is stepped hole, the bottom outlet section of stepped hole is small finger setting section 5a, the aperture Duan Wei great resilient key positioning section 6a of stepped hole, the length of small finger setting section 5a is less than the length of small pin 5, makes the small pin 5 be positioned in small finger setting section 5a protrude out in large resilient key positioning section 6a; The length of large resilient key positioning section 6a is less than the length of large resilient key 6, the large resilient key 6 be fitted in large resilient key positioning section 6a is protruded out in front end and can be pressed into workpiece pin-and-hole to arrive at workpiece spindle pin-and-hole.
As shown in Figure 1, in concrete enforcement, large resilient key positioning section is evenly provided with three resilient plunger 4 radially, adjustment resilient plunger 4 is at correct position, ensure that resilient plunger 4 has certain elastic force, utilize the large resilient key 6 of resilient plunger 4 riveting, make press-fiting in process and must not come off.
In order to ensure machining accuracy, as shown in Figure 1, metal bar being divided three sections of settings, is be segmentation position in the bottom surface, hole of stepped hole and the step place of stepped hole respectively, forms rear 1, stage casing 2 and leading portion 3, match with male and fomale(M&F) between each section, resilient plunger 4 is positioned on leading portion 3, and leading portion endoporus is large resilient key positioning section, and stage casing endoporus is small finger setting section, require that stage casing endoporus ensures that small pin can easily be put into, leading portion endoporus ensures that press-fiting large resilient key has certain positioning precision.
Press-fit process:
First small pin 5 is put into small finger setting section, then large resilient key 6 is placed in large resilient key positioning section, and keep small pin 5 and large resilient key 6 not to come off by resilient plunger 4, as shown in Figure 2.
Then, by the workpiece pin-and-hole of the front end alignment pieces 7 of large resilient key 6 protruded out, impact rear 1, the workpiece spindle pin-and-hole of workpiece spindle 8 is arrived in the front end directly causing large resilient key 6, and meanwhile, the front end of small pin 5 and the afterbody of large resilient key 6 are formed nestable, as shown in Figure 3.
Subsequently, take off two resilient key press-fitting tool, small pin 5 and large resilient key 6 remain on the workpiece pin-and-hole position of workpiece 7, as shown in Figure 4.
Finally, directly carry out riveting at the afterbody of small pin, make large resilient key be pressed into workpiece pin-and-hole and workpiece spindle pin-and-hole, and small pin is pressed in large resilient key, complete press-fiting of two resilient key in manual station gearbox shifting assembly, as shown in Figure 5.
