Description

Technical Field

[0002] The shift fork is a component of the car gearbox, connected to the shift handle, located at the lower end of the handle, and the middle shift wheel is turned to change the input / output speed ratio. The traditional shift fork has a simple structure, mostly composed of a single casting part. This kind of shift fork structure is simple and easy to process, but its function and applicability are poor. At present, the shift fork integrates more and more functions, and the adaptability of the shift fork is getting stronger and stronger, so the structure is more complicated. Figure 3 The shift fork assembly shown includes a shift fork component 151 and a shift fork component 2 152. The shift fork component 151 is provided with two positioning holes 151a and two pin holes 151b, and the shift fork component 2 152 is provided with two positioning holes 152a and two pin holes 152b. The pin shaft 153 is passed through the positioning holes 151a and 152a to achieve fixed connection between the shift fork component 151 and the shift fork component 2 152. In actual operation, the pin shaft 153 needs to be inserted into the positioning holes 151a and 152a and interference fit. Therefore, it is necessary to design a device to clamp and fix the two components of the shift fork together. Due to the special structure of this type of shift fork, the existing technology is not convenient for assembling this type of shift fork assembly.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a fork assembly assembly tool is provided, in order to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 5 As shown:

[0028] The utility model provides a fork assembly assembly tool, comprising:

[0029] A bracket 11 and a lifting mechanism 12 mounted on the bracket 11;

[0030] An upper die 13 and a lower die 14 arranged at the lower part of the upper die 13, the upper die 13 is provided with a pressure column 131 and a protection column 132, a protection pad 132a is arranged at the lower part of the protection column 132, the lower die 14 is provided with at least two positioning columns 141, a fork assembly 15 to be assembled is arranged on the lower die 14, the fork assembly 15 is provided with a fork component 1 151 and a fork component 2 152, the fork component 1 151 is provided with at least two positioning holes 151a and at least two pin holes 1 151b, the fork component 2 152 is provided with a positioning hole 2 152a and a pin hole 2 152b, the number of the pin holes 151b and the number of the pin holes 151b and the number of the pin holes 152b are the same and correspond one to one, the number of the positioning holes 151a and the number of the positioning holes 152a are the same and correspond one to one, and the pin hole 2 152b is provided with a pin shaft 153;

[0031] The number of positioning columns 141 and positioning holes 152a is the same and corresponds one to one, the number of pressure columns 131 and pin shafts 153 are the same and correspond one to one, and the lifting mechanism 12 can drive the upper mold 13 to move downward, and by pressing the pressure column 131 on the fork component 151 downward, the pin shaft 153 is inserted into the pin hole 152b and an interference fit is achieved.

[0032] When this embodiment is used, the fork assembly 15 is placed on the lower mold 14, and the upper mold 13 is driven downward by the lifting mechanism 12. The pressure column 131 on the upper mold 13 presses the fork component 151 downward, so that the pin hole 151b of the fork component 151 and the pin shaft 153 are interference-fitted, thereby realizing the assembly of the fork assembly 15. It has high applicability and is convenient and efficient to assemble the fork. The protection pad 132a contacts the fork component 151 before the pressure column 131, and the protection pad 132a is set to a soft silicone material, so as to play a certain buffering role to avoid damage to the fork assembly due to excessive impact force.

[0033] The upper die 13 is further provided with a buffer spring 133 .

[0034] The buffer spring 133 plays a buffering role. When the upper die 13 moves downward to approach the lower die 14, the buffer spring 133 contacts the local force-bearing area of ​​the lower fork assembly 15, thereby buffering the impact force of the pressure column 131 when it is pressed downward.

[0035] The lifting mechanism 12 is a hydraulic cylinder, which is provided with an actuator 121 and a cylinder body 122 . The lower end of the actuator 121 is fixedly connected to the upper mold 13 , and the cylinder body 122 is fixedly connected to the bracket 11 .

[0036] At least two sets of guide mechanisms 17 are arranged between the upper die 13 and the lower die 14 . The guide mechanism 17 includes a guide column 171 and a guide sleeve 172 slidably connected to the guide column 171 . The lower end of the guide column 171 is fixedly connected to the lower die 14 , and the guide sleeve 172 passes through and is fixedly connected to the upper die 13 .

[0037] The setting of the guide mechanism 17 enables the pressing column 131 to press down more accurately, and applies pressure to the pin hole 151b of the fork component 151 through the pressing column 131, so that the pin hole 151b and the pin shaft 153 are plugged and interference fit.

[0038] A limit block 16 is provided between the upper die 13 and the lower die 14. In a specific implementation, the limit block 16 is fixedly connected to the lower die 14, and the setting of the limit block 16 limits the downward movement distance of the upper die 13, so that the upper die 13 and the lower die 14 are at their closest positions, just enough to allow the pin shaft 153 to be completely inserted into the pin hole 151b and the pin hole 2 152b.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When the utility model is in use, the fork assembly 15 is placed on the lower mold 14, and the upper mold 13 is driven downward by the lifting mechanism 12, and the pressure column 131 on the upper mold 13 presses the fork component 151 downward, so that the pin hole 151b of the fork component 151 is interference-fitted with the pin shaft 153, thereby realizing the assembly of the fork assembly 15.

[0041] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
