Description

Technical Field

[0001] This application relates to the field of shift fork processing technology, and specifically discloses a shift fork inspection mold. Background Technology

[0002] The shift fork is a core component of the automotive transmission control mechanism. Different transmissions require shift forks with different structures to meet the needs of gear shifting. Figure 1 Taking the shift fork shown as an example, it consists of a main body, a connecting pin located in the middle of one side of the main body, and two fork legs located at the other end of the main body.

[0003] After the shift fork is manufactured and formed, various parameters need to be inspected to ensure that the product meets the usage specifications. For example, the overall dimensions of the main body, connecting pin, and fork feet need to be checked; the center distance of the connecting pin needs to be checked; and the fit and installation of the main body needs to be checked. However, in the current shift fork inspection process, the inspection molds are relatively simple in function, and different parameters require different molds. This results in the need for multiple molds and multiple inspection procedures to complete the shift fork inspection process. This is not only complex and labor-intensive, but also increases the cost of shift fork transportation. Furthermore, the need for repeated clamping and releasing of the shift fork can easily cause scratches on the surface of the shift fork, affecting the quality of the finished product. In view of this, this utility model provides a shift fork inspection mold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the traditional shift fork inspection process requires multiple inspection molds and multiple inspection procedures to complete the inspection of the shift fork, which leads to a complicated inspection process, tedious labor, and increased shift fork transportation costs.

[0005] To achieve the above objectives, the basic solution of this utility model provides a shift fork inspection mold, comprising:

[0006] Base plate;

[0007] The center positioning component is connected to the base plate and abuts against the two fork end faces of the shift fork.

[0008] Internal interference test block, the internal interference test block is connected to the base plate and is adapted to the side of the shift fork near the center positioning part;

[0009] Center distance inspection pin, which is slidably connected to the base plate and is adapted to the position of the fork shaft hole of the shift fork;

[0010] The no-go gauge is slidably connected to the base plate and perpendicular to the space of the fork shaft hole of the shift fork;

[0011] Inspection seat, which is located on the base plate and is adapted to the outer end face of the shift fork.

[0012] Furthermore, the base plate is provided with a first positioning groove corresponding to the position of the fork end of the shift fork, a second positioning groove corresponding to the position of the connection between the fork end and the main body, and a third positioning groove corresponding to the position of the fork shaft hole of the shift lever.

[0013] The central positioning component corresponds to the position of the first positioning groove, the internal interference inspection block corresponds to the position of the second positioning groove, and the center distance inspection pin corresponds to the position of the third positioning groove.

[0014] Furthermore, the center positioning component and the center positioning groove are provided with interconnected center positioning holes, and the center positioning holes are detachably connected to the opening mandrel.

[0015] Furthermore, it also includes a pin seat located directly above the first positioning groove and the second positioning groove, and a pin located on the pin seat and abutting against the outer end face of the fork leg of the shift fork.

[0016] Furthermore, the pin holder is provided with a positioning sleeve that allows the pin to slide.

[0017] Furthermore, it also includes a first fixed seat on the base plate that allows the center distance inspection pin to slide, and a second fixed seat on the base plate that prevents the go gauge from sliding.

[0018] Furthermore, the internal interference test block has several pin holes at the end away from the shift fork, and the pin holes are detachably connected to a fixing pin that mates with the base plate.

[0019] The principle and effect of this solution are as follows:

[0020] Compared with the prior art, this utility model can simultaneously inspect the distance between the fork legs, the center distance between the fork legs, the center distance between the fork shaft holes, and the internal and external assembly interference of the shift fork. It can perform inspection of multiple parameters of the shift fork in one mold, effectively improving the inspection efficiency of the shift fork, reducing the transportation cost of the shift fork, and avoiding the surface scratch problem caused by multiple clamping and releasing of the shift fork. It also solves the problem that the traditional shift fork inspection process requires multiple inspection molds and multiple inspection procedures to complete the inspection process, which leads to a complicated inspection process, tedious labor, and increased transportation cost of the shift fork.

[0027] A fork inspection mold, for example Figure 2 As shown: including base plate 2, center positioning component 3 on base plate 2, internal interference inspection block 9, center distance inspection pin 15, no-go gauge 14, and inspection seat 11, etc.;

[0028] like Figure 3 As shown, the base plate 2 is provided with a first positioning groove corresponding to the end position of the fork foot 103 of the shift fork 1, a second positioning groove corresponding to the connection position of the fork foot 103 and the main body 101 of the shift fork 1, and a third positioning groove corresponding to the position of the fork shaft hole of the shift lever.

[0029] The center positioning component 3 corresponds to the position of the first positioning groove. The center positioning component 3 and the center of the first positioning groove are provided with a central positioning hole that is mutually connected. The opening mandrel 4 is detachably connected to the center positioning hole by multiple fixing bolts 5. The two ends of the center positioning component 3 respectively abut against the inner end faces of the two fork legs 103 of the shift fork 1. The internal interference inspection block 9 corresponds to the position of the second positioning groove. The end of the internal interference inspection block 9 away from the shift fork 1 is provided with several pin holes 10. The internal interference inspection block 9 and the base plate 2 are fixed together by the cooperation of the fixing pins and the pin holes 10. Correspondingly, the base plate 2 is also bolted with pin seats 6 located directly above the first positioning groove and the second positioning groove respectively. Pins 7 are respectively provided on the pin seats 6 to abut against the outer end faces of the fork legs 103 of the shift fork 1. The pin seats 6 are provided with positioning sleeves 8 that allow the pins 7 to slide.

[0031] In this embodiment, the mounting reference position of the shift fork 1 is positioned by the internal interference inspection block 9, so that the inner wall of the main body 101 of the shift fork 1 fits with the internal interference inspection block 9. Then, the fork shaft hole of the connecting pin 102 of the shift fork 1 is inspected by the center distance inspection pin 15. The length between the fork shaft hole and the main body 101 of the shift fork 1 is checked according to the degree of fit between the center distance inspection pin 15 and the fork shaft hole. At the same time, the external parameters of the connecting pin 102 of the shift fork 1 are checked by the go gauge 14. The distance between the fork feet 103, the center distance between the feet, and the center distance of the fork shaft hole of the shift fork 1 are checked by the center positioning member 3. At the same time, the external parameters of the main body 101 of the shift fork 1 are checked by the inspection seat 11.

[0032] Compared with the prior art, this embodiment can simultaneously inspect the distance between the fork feet 103, the center distance between the fork feet 103, the center distance between the fork shaft holes of the shift fork 1, and the internal and external assembly interference of the shift fork 1. It can perform inspection of multiple parameters of the shift fork 1 in one mold, effectively improving the inspection efficiency of the shift fork 1, reducing the transportation cost of the shift fork 1, avoiding the surface scratch problem caused by multiple clamping and releasing of the shift fork 1, and solving the problem that the traditional shift fork 1 inspection process requires multiple inspection molds and multiple inspection procedures to complete the inspection process, resulting in a complicated inspection process, tedious labor, and increased transportation cost of the shift fork 1.
