Description

Technical Field

[0001] The utility model relates to the field of musical instrument manufacturing, in particular to a bevel processing device for a guitar handle joint. Background Art

[0002] In the guitar manufacturing process, the processing of guitar handle joints is an indispensable key link. The traditional processing method of guitar handle joints usually includes two main steps: first, according to the size requirements of the handle joint, the corresponding length of raw materials is cut by cutting equipment; then, according to the angle requirements of the bevel, the clamping angle needs to be adjusted so that the handle joint is fixed on the processing equipment at a specific tilt angle, and then the bevel cutting process is performed.

[0003] However, this traditional processing method has obvious shortcomings. On the one hand, the processing process is cumbersome and inefficient because the length cutting and beveling processing steps need to be performed separately. On the other hand, the saw blade milling cutter in the existing machine tools is often set to a horizontal or vertical state. If a bevel is to be processed on the shank joint, the inclination angle of the fixture must be adjusted. This adjustment not only increases the complexity of the operation, but also requires recalibration every time it is adjusted, making it difficult to ensure processing accuracy. In addition, the method of processing the shank joints one by one further reduces processing efficiency and increases production costs. Utility Model Content

[0049] Bevel processing:

[0050] The core of the bevel processing mechanism 5 is a milling cutter module, which includes a fixed frame, a saw blade milling cutter and a mechanical spindle.

[0051] The transmission motor 20 drives the mechanical main shaft to rotate, thereby driving the saw blade milling cutter to rotate. The saw blade milling cutter contacts the workpiece and cuts out a bevel.

[0071] Material grabbing and conveying:

[0072] The material grabbing mechanism 6 drives the material grabbing claw 21 to move up and down through the telescopic cylinder, grabs the guitar handle joint from the high-position feed port on the material rack, and places it on the workpiece clamping device 7.

[0073] The material rack and pushing device 8 realizes the reciprocating motion of the material through the telescopic cylinder, pushes the material from the discharge port to the unloading mechanism 9, and realizes the automatic transportation of the material.

[0074] Electrical Control:

[0075] The electrical control box 10 serves as the "brain" of the entire device, and realizes signal connection and control of the workpiece feeding mechanism 2, length CNC cutting mechanism, bevel processing mechanism 5, material grabbing mechanism 6, clamping device and pushing device through a single-chip microcomputer or a PLC programmable logic controller.
