[0024] A shaft bearing cap is a part that connects the automobile gearbox and the engine power output. A shaft bearing cap is a typical disc cover part. One end is a long sleeve shape and the other end is a disc shape. There are four to six bolt holes distributed on the large end face of the disc shape, and an oil hole is distributed on the circumference of the sleeve-shaped surface. The bolt hole and the oil hole need to be processed and have a certain spatial position relationship. There is a certain verticality requirement between the bolt hole and the large end face, otherwise it may break during actual work. If the hole is drilled from the end away from the large end face, the drill tool will extend too long and the drill tool rigidity will be poor, which is not conducive to improving the verticality. If the hole is drilled from the other side, although the verticality can be easily guaranteed, the entire part is not convenient to fix, and the part needs to be turned over during the subsequent processing of the oil hole, so it is not convenient during the processing.

[0025] See also Figure 1 , Figure 2 The present application provides a tool for processing a hole position on a shaft bearing cover, including a first positioning device 1 and a second positioning device 2. The first positioning device 1 includes a top plate 10, a bottom plate 11 and a connecting column 12. The top plate 10 and the bottom plate 11 are arranged at intervals. The connecting column 12 connects the top plate 10 and the bottom plate 11. A positioning hole 100 and a plurality of through holes 101 are provided on the top plate 10. The positioning hole 100 is used to correspond to the positioning port on the end cover of the shaft bearing cover. Each through hole 101 is used to correspond to the position of each hole to be processed on the end cover of the shaft bearing cover. The second positioning device 2 is arranged on one side of the first positioning device 1. The second positioning device 2 includes a fixture 21. The fixture 21 is used to clamp a drill tool, and the drill tool is used to drill oil holes on the sleeve of the shaft bearing cover.

[0026] During use, the bearing cover of the shaft is set between the top plate 10 and the bottom plate 11, so that the end cover of the bearing cover of the shaft is pressed against the lower side of the top plate 10, and then the bearing cover of the shaft is rotated so that the positioning port on the end cover of the bearing cover of the shaft is aligned with the positioning hole 100 on the top plate 10, and then the positioning pin is inserted into the positioning port and the positioning hole 100 to realize the positioning between the bearing cover of the shaft and the top plate 10. At this time, the positions corresponding to the through holes 101 on the top plate 10 are the positions of the holes to be processed on the end cover of the bearing cover of the shaft, and the hole positions can be processed on the end cover of the bearing cover of the shaft by drilling through the through holes 101. Since this processing method is to drill holes on the side close to the end cover, the verticality of the through holes 101 on the end cover of the bearing cover of the shaft can be guaranteed. The drilling tool is installed on the fixture 21, and the oil hole is processed on the sleeve of the bearing cover by the drilling tool. Since the position of the bearing cover of the shaft does not need to be adjusted again during the processing of the oil hole, the processing process is also more convenient.

[0027] The device is specially used to process various hole positions on the end cover of a shaft bearing cover and the oil holes on the sleeve of a shaft bearing cover, which effectively improves the processing efficiency. During the processing, the shaft bearing cover can be effectively fixed and has better stability.

[0028] The top plate 10 and the bottom plate 11 are both flat plate structures. The top plate 10 is a rectangular plate. The top plate 10 is arranged above the bottom plate 11 and parallel to the bottom plate 11. Four connecting columns 12 are arranged. One end of the four connecting columns 12 is respectively connected to the four corners of the top plate 10, and the other end is fixed to the bottom plate 11. The positioning hole 100 and each through hole 101 are respectively opened on the top plate 10. When the end cover of a shaft bearing cover is pressed against the lower side of the top plate 10, and the positioning port on the end cover of the shaft bearing cover is aligned with the positioning hole 100, it means that the end cover of the shaft bearing cover is installed in place.

[0029] In order to ensure that a shaft bearing cover can be pressed against the lower side of the top plate 10 , in some embodiments, the first positioning device 1 also includes a pushing device 13 , which is installed on the bottom plate 11 and is used to press a shaft bearing cover against the top plate 10 .

[0030] Specifically, the pushing device 13 is a cylinder, and the power output end of the pushing device 13 is upward, and a shaft bearing cover is pressed against the lower side of the top plate 10 by the pushing device 13.

[0031] In order to ensure that the shaft bearing cover is installed more accurately and stably on the lower side of the top plate 10, in some embodiments, a boss 102 is provided on the lower side of the top plate 10, and the boss 102 is used to cooperate with the groove on the end cover of the shaft bearing cover.

[0032] Specifically, a circular boss 102 is provided in the middle of the lower side of the top plate 10, and the boss 102 can cooperate with the groove on the end cover of a shaft bearing cover, so as to facilitate the end cover of the shaft bearing cover to correspond to the lower side of the top plate 10. At the same time, the end cover of the shaft bearing cover is more stably connected to the top plate 10 without relative sliding.

[0033] In some real-time streams, the second positioning device 2 is mounted on the bottom plate 11. In this way, the entire device forms an integrated structure, and the overall structure is more compact.

[0034] In some embodiments, the second positioning device 2 further includes a column 23 , the column 23 is fixed on the base plate 11 , and the clamp 21 is installed on the column 23 .

[0035] Specifically, the column 23 is vertically fixed on the base plate 11, and the clamp 21 is provided with a first clamping channel and a second clamping channel, wherein the first clamping channel and the second clamping channel are perpendicular to each other, the first clamping channel is clamped and fixed on the column 23, and the second clamping channel is horizontally arranged, which is used to clamp the drilling tool for drilling oil holes.

[0036] In order to facilitate the adjustment of the height of the clamp 21 to process oil holes at different heights, in some embodiments, the clamp 21 is detachably mounted on the column 23 .

[0037] Specifically, an opening is provided on the first clamping channel, and the opening extends along the length direction of the first clamping channel and passes through the two ends of the first clamping channel. Connecting plates extending outward are provided on both sides of the opening, and connecting holes are provided on the connecting plates. After the first clamping channel is sleeved on the column 23, bolts are passed through the connecting holes, and nuts are tightened on the bolts to connect the connecting plates on the opening, so that the first clamping channel is clamped on the column 23. When the height of the clamp 21 needs to be adjusted, the nuts are loosened and the clamp 21 can be adjusted along the column 23.

[0038] The structure of the second clamping channel is the same as that of the first clamping channel, and will not be described in detail here.

[0039] In order to ensure that the clamp 21 is held more firmly on the column 23, in some embodiments, the second positioning device 2 also includes a clamping block 20, which is installed on the column 23 and pressed on the top of the clamp 21. The clamping block 20 is provided with a clamping plate 200 that is clamped on both sides of the clamp 21.

[0040] Specifically, the clamping block 20 has a clamping end, and the clamping end of the clamping block 20 is sleeved on the column 23 and clamped. Since the clamp 21 is used to clamp the drilling tool, the drilling tool will vibrate during operation, and the clamp 21 can be limited by the clamping block 20 to prevent the clamp 21 from moving upward along the column 23. In addition, the clamping plates 200 on both sides of the clamping block 20 can limit the clamp 21 to prevent the clamp 21 from rotating on the column 23.

[0041] In some other embodiments, the second positioning device 2 further includes a cushion block 22 . There are multiple cushion blocks 22 , each cushion block 22 has a different thickness, and the cushion blocks are mounted on the columns 23 and supported below the clamp 21 .

[0042] After the clamp 21 is adjusted into place on the column 23, a cushion block 22 is installed on the column 23 to support the bottom of the clamp 21. In this way, the clamp 21 is limited by the clamping block 20 above and supported by the cushion block 22 below. The stability of the entire clamp 21 is better, and the drilling tool installed on the clamp 21 is also more stable during operation.

[0043] In some embodiments, the cushion block 22 is a U-shaped block structure that is sleeved on the column 23. During use, the cushion block 22 can be directly nested on the column 23.

[0044] In order to ensure that the pad 22 is stably installed on the column 23 and the support is more firm, in some embodiments, the bottom of the column 23 is provided with a step surface 231 that limits the pad 22. After the pad 22 is nested on the column 23, one end surface of the pad 22 is pressed against the step surface 231, and the other end surface is pressed against the lower side of the clamp 21.

[0045] In the present application, a conical platform 230 is provided at the bottom of the column 23 , and a top of the conical platform 230 forms a step surface 231 that defines the cushion block 22 .

[0046] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
