Description

Technical Field

[0001] The present application relates to the field of furniture technology, and in particular to a tooling fixture for machining sprocket outer teeth. Background Art

[0002] During the processing of the sprocket, some special sprockets need to be processed on both sides of the sprocket. When the outer teeth of the sprocket need to be processed, two sets of clamps are needed in the prior art.

[0003] After the sprockets are clamped and fixed, the two sides of the outer teeth of the sprockets are processed respectively. This technical solution requires the use of two sets of clamps and two processing tools to process the outer teeth of the sprockets, which is relatively cumbersome and requires two clamps, resulting in a waste of materials. Utility Model Content

[0004] In order to reduce material waste, the present application provides a tooling fixture for machining sprocket outer teeth.

[0005] The present application provides a tooling fixture for machining sprocket outer teeth using the following technical solution:

[0006] A tooling fixture for processing sprocket outer teeth comprises a mounting platform and a mounting base, wherein the mounting base is arranged on the mounting platform, the upper surface of the mounting base has a mounting cavity, the bottom wall of the mounting cavity is coaxially provided with a positioning rod, and the mounting base is provided with a cover plate, which is used to clamp the sprocket on the mounting base.

[0007] By adopting the above technical solution, the sprocket is installed on the mounting base, and the sprocket is clamped and installed on the mounting base through the cover plate. During processing, the sprocket can be clamped in both directions to facilitate installation on the upper and lower sides of the sprocket, and the clamping is relatively convenient, thereby improving the convenience of processing.

[0008] Optionally, the mounting base is provided with a driving rod for driving the cover plate to move toward the mounting base, the driving rod is slidably connected to the mounting base along the vertical direction, a clamping block is provided at the upper end of the driving rod, the diameter of the clamping block is larger than the diameter of the driving rod, and the mounting base is provided with a driving member for driving the driving rod to move.

[0009] By adopting the above technical solution, after the cover plate is placed on the mounting base, the driving member drives the driving rod to move downward, so that the pressing block is pressed against the cover plate, and then the sprocket is clamped on the mounting base.

[0010] Optionally, the cover plate is coaxially penetrated with a first hole, the diameter of the first hole is consistent with the diameter of the driving rod, the cover plate is penetrated with a second hole, the diameter of the second hole is larger than the diameter of the clamping block, and the second hole is connected to the first hole.

[0011] By adopting the above technical solution, when installing the cover plate, the clamping block is penetrated through the second penetration hole on the upper side of the cover plate, and then the cover plate is moved so that the driving rod is located in the first penetration hole, thereby facilitating the subsequent clamping of the clamping block.

[0012] Optionally, a moving block is provided on the mounting platform, and a limiting block adapted to the outer teeth of the sprocket is provided on the moving block.

[0013] By adopting the above technical solution, after installing the cover plate, the moving block is moved so that the limiting block is clamped on the outer teeth of the sprocket, thereby further limiting the position of the sprocket.

[0014] Optionally, the limit block is connected to the moving block in a sliding manner in a direction close to the mounting base, and the moving block is provided with a first elastic member for forcing the limit block to slide in a direction close to the mounting base.

[0015] By adopting the above technical solution, in order to avoid the abutment force of the limit block being too large to cause damage to the outer teeth of the sprocket, the limit block can slide relative to the movable block. When clamped, the limit block can move adaptively and force the limit block to be clamped on the sprocket through the first elastic member, thereby reducing the possibility of damage to the sprocket.

[0016] Optionally, a threaded hole is coaxially formed on the end surface of the clamping block, and the upper end of the driving rod has a threaded portion, which is threadedly connected to the threaded hole.

[0017] By adopting the above technical solution, the height of the pressing block after deposit can be adjusted by rotating the pressing block, so that the device can be adapted to clamp sprockets of different thicknesses.

[0018] Optionally, the clamping block is slidably connected to the driving rod along the vertical direction, and the clamping block is provided with a limiting member for limiting the sliding position.

[0019] By adopting the above technical solution, the clamping block is slidably connected to the driving rod, and the height of the clamping block can be adjusted, so that the device can be adapted to clamp sprockets of different thicknesses.

[0020] Optionally, the deposit block is slidably connected to a limit rod, the driving rod is provided with a plurality of limit holes for inserting the limit rod, the plurality of limit holes are distributed along the axial direction of the driving rod, and the clamping block is provided with a second elastic member for forcing the limit rod to be clamped in the limit hole.

[0021] By adopting the above technical solution, when adjusting the clamping block, the limiting rod is clamped in different limiting holes, so as to adjust different heights of the clamping block and limit the clamping block to facilitate subsequent clamping of the cover plate.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. After placing the cover plate on the mounting base, the driving member drives the driving rod to move downward, so that the pressing block is pressed against the cover plate, and then the sprocket is clamped on the mounting base;

[0024] 2. In order to prevent the abutment force of the limit block from being too large to cause damage to the outer teeth of the sprocket, the limit block can slide relative to the moving block. When it is locked, the limit block can move adaptively and force the limit block to be locked on the sprocket through the first elastic member, thereby reducing the possibility of damage to the sprocket.
