Description

Technical Field

[0001] The utility model belongs to the field of shift fork shafts, and in particular relates to a shift fork shaft auxiliary assembly device. Background Art

[0002] The shift fork shaft of a car transmission guides the movement of the shift fork in the transmission. Usually, the shift fork shaft and the shift fork are connected by screws. When installing the shift fork shaft, it needs to be fixed by a fixing pin. When installing the fixing pin, the fixing pin needs to be supported manually, which makes it easier to injure your hands when knocking. Moreover, if you knock the pin too hard, the pin may be knocked out from the bottom and fall into other parts, making it difficult to find. Utility Model Content

[0003] The utility model aims at solving the deficiencies of the prior art and provides a fork shaft auxiliary assembly device.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fork shaft auxiliary assembly device, comprising a fork shaft, wherein a pin hole is provided in the fork shaft, and the characteristics are: an upper cover is detachably installed in the pin hole, and an auxiliary component is sleeved on the outer peripheral side of the fork shaft;

[0005] The auxiliary component includes an upper cover and a lower cover, and the upper cover and the lower cover are connected together by two connecting rods. A sleeve is slid on the connecting rod, and a telescopic rod is fixed on the sleeve. A positioning cover is provided on the telescopic rod, and the position of the positioning pin is positioned by the positioning cover.

[0006] Optionally, at least two connecting edges are provided on the upper cover and the lower cover, and the connecting edges are semi-arc-shaped and installed on the connecting rods on both sides.

[0007] Optionally, the curvature of the upper cover and the lower cover are both smaller than the curvature of the sleeve.

[0008] Optionally, a support rod is fixed on the sleeve, and a material discharge trough is opened in the positioning cover, and the top end of the material discharge trough is expanded.

[0009] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Due to the setting of the auxiliary components, the upper cover and the lower cover can be set to make the installation convenient and quick, and no manual support is required when installing the pin shaft, which effectively solves the problem of hand injuries of the staff. In addition, blocking the bottom of the pin hole by the upper cover or the lower cover can effectively prevent the pin shaft from falling out of the pin hole due to excessive knocking force.

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0016] As shown in Figures 1-3, a fork shaft auxiliary assembly device includes a fork shaft 10, a pin hole 20 is provided in the fork shaft 10, an upper cover 12 is detachably installed in the pin hole 20, an auxiliary component is sleeved on the outer peripheral side of the fork shaft 10, the auxiliary component includes an upper cover 12 and a lower cover 13, the upper cover 12 and the lower cover 13 are connected together by two connecting rods 14, at least two connecting edges 17 are provided on the upper cover 12 and the lower cover 13, the connecting edges 17 are semi-arc-shaped, and the connecting edges 17 are installed on the connecting rods 14 on both sides, the curvature of the upper cover 12 and the lower cover 13 is smaller than the curvature of the sleeve 18, a sleeve 18 is slid on the connecting rod 14, a telescopic rod is fixed on the sleeve 18, a positioning cover 15 is provided on the telescopic rod, the position of the pin shaft 11 is positioned by the positioning cover 15, a support rod 16 is fixed on the sleeve 18, a feed trough 19 is opened in the positioning cover 15, and the top of the feed trough 19 is expanded.

[0017] When in use, first put the upper cover 12 and the lower cover 13 on the fork shaft 10. When the pin shaft 11 and the pin hole 20 are in a clearance fit, it is necessary to block the bottom hole, and then move the entire device so that the lower cover 13 is blocked below the pin hole 20. At this time, push the positioning cover 15 so that the positioning cover 15 is aligned on the pin hole 20, and the pin shaft 11 is placed properly, effectively preventing the pin shaft 11 from falling directly. When the pin shaft 11 and the pin hole 20 are in an interference fit, it is possible to choose whether to block the bottom of the pin hole 20 as needed. When blocking is required, the above operation is performed. When blocking is not required, the upper cover 12 and the lower cover 13 are located on both sides of the pin hole 20, and then the position of the positioning cover 15 is adjusted to install the pin shaft 11. When knocking the pin shaft 11, blocking the bottom of the pin hole 20 can effectively prevent the pin shaft 11 from falling due to excessive knocking force. After the pin shaft 11 is installed, the positioning cover 15 can be pulled upward to remove the entire device.

[0018] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
