Front fork vertical rod cutting jig

Abstract

The invention discloses a front fork vertical rod cutting jig. The front fork vertical rod cutting jig comprises a base, a size positioning block, a clamping and positioning device, a saw blade support, a saw blade, a saw blade driving device and a control switch, the clamping and positioning device on the base can fix a to-be cut front fork vertical rod, the saw blade support comprises a fixed frame and a movable frame, the fixed frame is fixed to the base, the movable frame is axially stopped along the to-be-cut front fork vertical rod and is mounted on the fixed frame in a manner of moving along the radial direction of the to-be-cut front fork vertical rod, the saw blade is rotationally mounted on the movable frame of the saw blade support, the saw blade driving device drives the saw blade to rotationally saw the front fork vertical rod fixed by the clamping and positioning device, the control switch controls the saw blade driving device to start and stop, the size positioning block can be fixedly installed on the base, and the stopping face on the size positioning block is stopped on the surface of a shoulder of the to-be-cut front fork vertical rod, fixed-length tailoring of bicycle vertical rods of different specifications is achieved, use is convenient, tailoring of the front fork vertical rod is accurate, tailoring efficiency is high, and labor is saved.

Description

technical field [0001] The invention relates to a processing jig for bicycle parts, in particular to a cutting jig for a front fork vertical bar. Background technique [0002] The bicycle front fork is used to install the front wheel. At present, in order to improve the overall strength of the vehicle and reduce the weight of the frame, carbon fiber is used to produce the bicycle front fork. The length of the front fork vertical rod varies with different models. After the production of the front fork vertical rod is completed , needs to go through the cutting steps to realize the fixed length of the front fork vertical bar. At present, the fixed length cutting of the front fork vertical bar is firstly measured by a ruler, then the front fork vertical bar is fixed and positioned, and then sawed with a saw blade. There will be dimensional errors in the length of the rear fork vertical bar, which often requires multiple trimmings. This method of cutting the front fork vertical ...

[0002] The bicycle front fork is used to install the front wheel. At present, in order to improve the overall strength of the vehicle and reduce the weight of the frame, carbon fiber is used to produce the bicycle front fork. The length of the front fork vertical rod varies with different models. After the production of the front fork vertical rod is completed , needs to go through the cutting steps to realize the fixed length of the front fork vertical bar. At present, the fixed length cutting of the front fork vertical bar is firstly measured by a ruler, then the front fork vertical bar is fixed and positioned, and then sawed with a saw blade. There will be dimensional errors in the length of the rear fork vertical bar, which often requires multiple trimmings. This method of cutting the front fork vertical bar results in low cutting efficiency and requires repeated measurements. The dimensional accuracy after cutting is low, which affects the overall accuracy of the bicycle and is labor-intensive. , high production cost
