Description

Technical Field

[0001] The utility model belongs to the technical field of angle measuring devices, and in particular relates to a mounting angle measuring device for a bearing cover of an output shaft of a power take-off. Background Art

[0002] As a device that connects the transmission sub-box or output shaft to output power externally, the power take-off is widely used in the whole vehicle. In order to improve the matching degree between a certain transmission and the whole vehicle of different OEMs, the installation angle of the output shaft bearing cap of the power take-off is changed to meet the power output of different vehicles. Therefore, it is necessary to use measuring equipment or rely on the operator's visual inspection to check whether the installation angle of the output shaft bearing cap of the power take-off meets the assembly process requirements.

[0003] There are relatively mature electronic measuring equipment on the market, but these devices have disadvantages such as high price, high specialization, easy damage, and unsuitable for measuring irregular parts. The assembly site still relies solely on manual visual inspection to see if the installation angle is correct.

[0004] The Chinese utility model patent with publication number CN212839288U discloses a convenient power take-off that is easy to clamp. It is equipped with a connecting plate, a rotating shaft, a fixing rod, a fixing bolt, etc. The fixed connection between the fixing rod and the rotating shaft makes it easy for the staff to adjust the angle of the gear, thereby facilitating the engagement of the gear with the gear teeth of the gearbox, thereby improving the installation efficiency between the power take-off body and the gearbox by the staff. At the same time, the position of the protective shell can be fixed by the connecting plate, the threaded groove and the fixing bolt, thereby preventing the protective shell from being displaced during use.

[0005] However, this method is greatly affected by human factors and there is a risk of quality accidents and customer complaints due to incorrect installation angles. To address this problem, a device for measuring the installation angle of the output shaft bearing cap of a power take-off needs to be designed, which can assist manual inspection of whether the installation angle of the output shaft bearing cap is correct while meeting the requirements of production cycle, low cost, multi-angle switching, and simple operation. Utility Model Content

[0006] In order to improve the off-line qualified rate of the transmission, it is necessary to detect the installation angle of the output shaft bearing cover of the power take-off to check and confirm whether the installation angle meets the assembly process requirements. The measurement objects at the assembly site are non-planar and irregular parts, and it is impossible to directly purchase ready-made electronic measuring equipment, so customization is required. However, the procurement cost is high, the compatibility of the measuring equipment is poor, and the subsequent maintenance is difficult; relying solely on manual visual inspection of the installation angle is risky. The utility model proposes an installation angle measuring device for the output shaft bearing cover of the power take-off.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A device for measuring the installation angle of a bearing cap of an output shaft of a power take-off comprises an output shaft bearing cap positioning plate, a bolt positioning plate, an output shaft bearing cap positioning rod, a bolt positioning rod, an output shaft positioning ring and bolts.

[0009] The output shaft bearing cover positioning plate is connected to the output shaft positioning ring and the bolt positioning plate through bolts, and the bolt positioning plate is connected to the bolt positioning rod and the output shaft bearing cover positioning plate and the output shaft bearing cover positioning rod through threads.

[0010] In the above-mentioned angle measuring device, the bolt positioning rod matches the output shaft bearing cover of the power take-off, and the output shaft positioning ring and the output shaft bearing cover positioning rod are aligned with the output shaft of the power take-off and the threaded hole at the upper right corner of the output shaft bearing cover.

[0011] In the above-mentioned angle measuring device, the bolt positioning rod is axially aligned with the product bolt on the right side of the output shaft bearing cover in the horizontal direction, and the installation angle is correct.

[0012] The beneficial effects of the utility model are:

[0013] A device for measuring the installation angle of a bearing cap of a power take-off output shaft, which can be disassembled and assembled, and can measure multiple angles. According to the size of the installation angle of the bearing cap of the power take-off output shaft required by a certain transmission technical agreement, by changing the assembly position of the measuring device parts, using the structural limit of the device, and assisting the operator in visual inspection, the purpose of measuring the installation angle of the bearing cap of the power take-off output shaft is achieved;

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The present application provides an output shaft bearing cover positioning plate, a bolt positioning plate, an output shaft bearing cover positioning rod, a bolt positioning rod, an output shaft positioning ring and bolts. The installation angle is determined by observing the relative position of the bolt positioning rod and the product bolt on the right side of the output shaft bearing cover in the horizontal direction.

[0024] Embodiment 1

[0025] A device for measuring the installation angle of a bearing cap of a power take-off output shaft comprises an output shaft bearing cap positioning plate 1, a bolt positioning plate 2, an output shaft bearing cap positioning rod 3, a bolt positioning rod 4, an output shaft positioning ring 5 and a bolt 6. Figure 1 , 2 As shown. The output shaft bearing cover positioning plate 1 and the output shaft positioning ring 5 and the bolt positioning plate 2 are connected by bolts 6, and the bolt positioning plate 2 and the bolt positioning rod 4, the output shaft bearing cover positioning plate 1 and the output shaft bearing cover positioning rod 3 are connected by threads. The device has a simple structure and strong applicability. By quickly switching the installation position of the bolt positioning rod, multi-angle measurement can be achieved.

[0026] During on-site operation, according to the installation angle requirements of the output shaft bearing cover 8 of a certain type of power take-off of the transmission, select the installation position of the bolt positioning rod 4 and assemble the corresponding angle measuring device. Figure 3 As shown, the structure includes a power take-off housing 7, an output shaft bearing cap 8, a product bolt 11, and an output shaft 9. Due to the structural characteristics of the output shaft bearing cap 8, there are two states after installation (there are two angles between the right product bolt 11 in the horizontal direction and the output shaft bearing cap threaded hole 10 adjacent thereto), so it is necessary to check and confirm the angle after installation.

[0027] Align the output shaft positioning ring 5 and the output shaft bearing cover positioning rod 3 of the measuring device with the output shaft 9 on the power take-off and the threaded hole 10 at the upper right corner of the output shaft bearing cover 8, and observe the relative position of the bolt positioning rod 4 and the product bolt 11 on the right side of the horizontal direction of the output shaft bearing cover 8. If the bolt positioning rod 4 is aligned with the axial direction of the bolt on the right side of the horizontal direction of the output shaft bearing cover 8, the installation angle is correct; if it is in other states, it is necessary to adjust it online, reinstall the output shaft bearing cover 8, and use the device for detection until the bolt positioning rod 4 is aligned with the axial direction of the bolt on the horizontal direction of the output shaft bearing cover 8, and then the transmission can be released.

[0028] The two angle measurement methods for the other three types of power take-offs are the same as those in the above embodiment, and only attention needs to be paid to the installation position of the bolt positioning rod 4.
