Description

Pulley dismounting device

The present invention provides a pulley dismounting device that can accommodate different disassembly environments of the pulley.

The latest prior art is shown in the previous case of China Patent No. 102220397. However, the original intention of this creator is to continue to analyze the patent case and find that it still has insufficient function in response to different disassembly environments of the pulley. At the office.

1. In order to disassemble the environment in response to the different pulleys, it is necessary to replace the jaws of the corresponding specifications. However, in order to disassemble the two jaws, all the components except the ejector must be disassembled one by one. Such replacement is quite slow and trouble.

Second, the manufacture of different specifications of the jaws, in addition to not economic benefits, and considerable storage space.

In view of this, the creator has developed the new model with years of professional experience and experience, through continuous conceiving and research.

The present invention provides a pulley dismounting device, which comprises at least: a guiding rod, which radially penetrates a guiding screw hole for screwing the jack; a two clamping arm having a guiding hole capable of sliding along the axial direction of the guiding rod and not rotating, and a first rail and a first clamping portion, the first rail axial direction being relatively perpendicular to the guiding screw hole axial direction; a claw member provided with a second rail matching the first rail for detachably mounting the claw member to the corresponding clip arm, and positioning the second card portion matching the first card portion with each other; and the two claw members The opposite side of the buckle portion enables the two clamping arms to drive the two buckle portions toward the periphery of the fitting pulley, thereby providing the detachable pulley to disassemble the pulley.

The reason is that the present invention mainly improves the prior art jaws into separate clamp arms and claw members. Therefore, the present invention does not need to disassemble the two clamp arms when the belt pulley is disassembled in different environments, and only needs to replace different specifications. The clamping member can be used, and the clamping member has the advantages of low cost and less space occupation. Therefore, the prior art has no waste and a lot of inconvenience in replacing the entire clamping jaw, and the assembly and disassembly of the claw member is quite easy and fast. Therefore, the present invention does provide an innovative technique for effectively solving the pulley dismounting device.
