Description

Technical Field

[0001] The utility model relates to the field of installation, in particular to a special installation tool for a cutter shaft oil seal. Background Art

[0002] At present, when replacing and installing the oil seal of the inner liner paper cutter shaft of the YB45 packaging machine, it usually takes several hours to disassemble the inner liner paper cutter assembly, remove the old oil seal, and then use a copper rod or nylon rod to knock the new oil seal into the machine wall along the inner liner paper cutter shaft (driving wheel cutter shaft and driven wheel cutter shaft), and finally install the inner liner paper cutter assembly to complete the replacement of the two oil seals. Because the inner liner paper cutter shaft (driving wheel cutter shaft and driven wheel cutter shaft) protrudes from the machine wall where the oil seal is installed for a long distance, it is usually necessary to rely on copper rods or nylon rods to knock on each side of the oil seal multiple times, resulting in uneven force on each side of the oil seal and a long installation time, which can easily cause the oil seal to be installed improperly or damaged, seriously reducing the service life of the oil seal and increasing the replacement frequency of the oil seal. In addition, due to the cumbersome disassembly and installation steps of the inner liner paper cutter assembly, frequent replacement of the cutter shaft oil seal is time-consuming and labor-intensive, which seriously affects the efficiency of maintenance. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present application discloses a special installation tool for a cutter shaft oil seal, the installation tool comprising a first tool and a second tool, the first tool comprising a first force-bearing shaft and a first countersunk section, the second tool comprising a second force-bearing shaft and a second countersunk section; the cutter shaft comprises a driving wheel cutter shaft and a driven wheel cutter shaft, the driving wheel cutter shaft and the driven wheel cutter shaft are respectively inserted into the machine wall, a driving wheel oil seal is arranged between the driving wheel cutter shaft and the machine wall, and a driven wheel oil seal is arranged between the driven wheel cutter shaft and the machine wall; the The first countersunk section can be inserted into the driving wheel cutter shaft, the length of the first countersunk section is greater than the length of the driving wheel cutter shaft exposed from the machine wall, the lower surface of the first countersunk section contacts the driving wheel oil seal, and the lower surface of the first force-bearing shaft does not contact the upper surface of the driving wheel cutter shaft; the second countersunk section can be inserted into the driven wheel cutter shaft, the length of the second countersunk section is greater than the length of the driven wheel cutter shaft exposed from the machine wall, the lower surface of the second countersunk section contacts the driven wheel oil seal, and the lower surface of the second force-bearing shaft does not contact the upper surface of the driven wheel cutter shaft.

[0004] The inner diameter of the first countersunk hole section is larger than the outer diameter of the driving wheel cutter shaft, and the inner diameter of the second countersunk hole section is larger than the outer diameter of the driven wheel cutter shaft.

[0005] The first force-bearing shaft is integrally connected to the first countersunk section, and the second force-bearing shaft is integrally connected to the second countersunk section.

[0006] The length of the first force-bearing axis is 100.0 mm, and the diameter is 49.4 mm. The length of the second force-bearing axis is 100.0 mm, and the diameter is 46.4 mm.

[0007] The inner diameter of the first countersunk hole section is 38.0 mm, and the settlement depth of the first countersunk hole section is 320 mm; the inner diameter of the second countersunk hole section is 32.4 mm, and the settlement depth is 320 mm.

[0008] The first force-bearing shaft is screwed to the first tool, and the first force-bearing shaft can be rotated in the first tool to adjust the sinking depth of the first countersink section.

[0009] The first force-bearing shaft is spirally connected to the first tool, and the first force-bearing shaft can be rotated in the first tool to adjust the sinking depth of the first countersunk section, so that the first tool and the second tool can adapt to cutter shafts of different lengths or different insertion depths in the machine wall.

[0010] The installation tool also includes a first clamp, a second clamp, and a common force-bearing axis. The first clamp is arranged on the outer surface of the first tool, and the second clamp is arranged on the outer surface of the second tool. The two ends of the common force-bearing axis are respectively inserted into the first clamp and the second clamp, so that by applying pressure to the common force-bearing axis, the pressure can be transmitted to the first force-bearing axis and the second force-bearing axis simultaneously through the first clamp and the second clamp, thereby applying pressure to the first oil seal and the second oil seal at the same time, providing stability and synchronization of the force of the first oil seal and the second oil seal, and improving efficiency and sealing effect.

[0011] The position of the first fixture on the first tool is the same as the position of the second fixture on the second tool.

[0012] The spacing of the first clamps is greater than the outer diameter of the common force-bearing shaft, the spacing of the second clamps is greater than the outer diameter of the common force-bearing shaft, the spacing of the first clamps is the same as the spacing of the second clamps, and the outer diameter of the common force-bearing shaft is smaller than the gap of the spacing, so that the common force-bearing shaft is in a loose state after being inserted into the first clamp and the second clamp. Therefore, when the insertion distances of the first oil seal and the second oil seal in the machine wall are different, there is no need to adjust the first oil seal or the second oil seal by applying force to the first tool or the second tool separately in advance, but force can still be applied to the common force-bearing shaft to apply force to the first oil seal and the second oil seal at the same time. Since the common force-bearing shaft is in a loose state in the first clamp and the second clamp, different forces can be applied to the first oil seal and the second oil seal. For example, if the exposed part of the first oil seal is longer than the second oil seal, the force on the first oil seal will be greater than the second oil seal. As the force is applied, the first oil seal and the second oil seal can finally be subjected to the same force and inserted into the machine wall at the same time;

[0013] This application has the following advantages:

[0014] The oil seal installation special tool of the utility model is used to install the oil seal of the liner paper cutter shaft (driving wheel cutter shaft and driven wheel cutter shaft) of the YB45 packaging machine. The oil seal installation process is convenient, fast and accurate, which can effectively reduce the installation time, ensure the installation accuracy of the oil seal, and increase the service life of the oil seal.

The lower surface of the second countersunk section 22 contacts the driven wheel oil seal 23, and the lower surface of the second force-bearing shaft 21 does not contact the upper surface of the driven wheel cutter shaft 24.

[0026] The inner diameter of the first counterbore section 12 is larger than the outer diameter of the driving wheel cutter shaft 14 , and the inner diameter of the second counterbore section 22 is larger than the outer diameter of the driven wheel cutter shaft 24 .

[0027] The first force-bearing shaft 11 is integrally connected to the first countersunk section 12 , and the second force-bearing shaft 21 is integrally connected to the second countersunk section 22 .

[0028] The first force-bearing shaft 11 has a length of 100.0 mm and a diameter of 49.4 mm. The second force-bearing shaft 21 has a length of 100.0 mm and a diameter of 46.4 mm.

[0030] The first force-bearing shaft 11 is screwed to the first tool 1, and the first force-bearing shaft 11 can be rotated in the first tool 1 to adjust the sinking depth of the first countersunk hole section 12. Figure 7 As shown, the second tool may also have a similar design, which will not be described in detail.

[0031] The first force-bearing shaft 11 is spirally connected to the first tool 1, and the first force-bearing shaft 11 can be rotated in the first tool 1 to adjust the sinking depth of the first countersunk section 12, so that the first tool 1 and the second tool 2 can adapt to cutter shafts of different lengths or different insertion depths in the machine wall 5.

The second tool 2 applies force to adjust the first oil seal or the second oil seal, while still being able to apply force to the common force-bearing shaft 33 to simultaneously apply force to the first oil seal and the second oil seal.

For example, if the exposed portion of the first oil seal is longer than that of the second oil seal, the force applied to the first oil seal will be greater than that of the second oil seal. As the force is applied, the first oil seal and the second oil seal can finally be subjected to the same force and inserted into the machine wall 5 at the same time.
