Example Embodiment

[0015] The present invention will be further described in detail below through specific implementations:

[0016] The reference signs in the drawings of the specification include: eccentric wheel 1, lever 2, V-shaped block 3, drill sleeve 4, and supporting block 5.

[0017] The embodiment is basically like figure 1 Shown: The tooling for drilling the fixed shaft of the pulley includes a base, an eccentric wheel 1, a lever 2, a V-shaped block 3, a drill sleeve 4, and a supporting block 5. The base is provided with a C-shaped supporting arm and the back of the supporting arm The pivotal eccentric wheel is provided with a handle for easy rotation of the eccentric wheel. The middle part of the lever is pivoted at the lower end of the supporting arm. The supporting block is located on the abdomen of the supporting arm. The lower end of the supporting block is a rod that is slidably connected with the supporting arm. There is also a bushing between the supporting arms. The bushing can r...

Abstract

The invention discloses a belt pulley fixed shaft drilling tool which comprises a base and further comprises an eccentric wheel, a lever, a V-shaped block, a drill sleeve and a bearing block. A C-shaped bearing arm is arranged on the base, the eccentric wheel is pivoted on the back of the bearing arm, the middle of the lever is pivoted at the lower end of the bearing arm, the bearing block is located on the web portion of the bearing arm, the lower end of the bearing block is the rod portion in sliding connection with the bearing arm, the lower end of the rod portion abuts against the right end of the lever, a spring connected with the right end of the lever and the bearing arm sleeves the rod portion, the left end of the lever abuts against the rim of the eccentric wheel, an anti-rotating groove is formed in the middle of the rod portion in the sliding direction, an anti-rotating screw inserted into the anti-rotating groove is arranged on the lateral wall of the bearing arm, the upper end of the bearing arm is connected with a drilling template, the V-shaped block is arranged on the drilling template, the V-shaped block is located right above the bearing block, and a drill sleeve is embedded in the center of the V-shaped block. The tool facilitates clamping, is easy to operate, capable of fixing the belt pulley fixed shaft quickly and greatly improves production efficiency.

Description

technical field [0001] The invention relates to a tool for drilling a fixed shaft of a belt pulley. Background technique [0002] Belt drive is a very commonly used transmission method. In belt drive, the pulley and its fixed shaft are very common. [0003] In addition to the key connection between the pulley and the fixed shaft of the pulley, it is usually necessary to drill holes in the circumferential direction of the fixed shaft of the pulley and fix the pulley and the fixed shaft of the belt road firmly by set screws. [0004] The inventor encountered a problem when drilling the fixed shaft of the pulley in the circumferential direction. The clamping tool in the prior art is often not fixed firmly or the operation is too complicated when clamping the fixed shaft of the pulley, which not only affects the machining accuracy, And it affects the production efficiency. Contents of the invention [0005] The invention intends to provide a tool for drilling a fixed shaft o...
