Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, and in particular to a special fixture for screw processing. Background Technology

[0002] A screw is a cylinder with a helical groove cut on its outer surface or a cone with a conical helical groove cut on its outer surface; screws have different heads, the head of which is called an external hexagonal screw; there are others, such as large flat screws, internal hexagonal screws, etc.

[0003] However, the screw clamps currently in use can only hold screws of a single size when installed and fixed, and cannot be adjusted according to different screw sizes. In addition, the rust prevention treatment on the screw surface is mostly done by manual spraying by workers. Prolonged contact with rust-preventive liquid can easily cause damage to the workers' bodies.

[0004] In view of this, this paper studies and improves the existing problems to provide a special fixture for screw processing. It has a reasonable structural design, integrates adjustability, automatic spraying, and ease of use, reduces manpower and material resources, and greatly improves work efficiency. The aim of this technology is to solve the problem and improve its practical value. Utility Model Content

[0007] As a further description of the above technical solution:

[0008] The first and second slides are equipped with threaded rods inside, and the first drive motor, the threaded rods, the first slides, the slider, and the moving plate constitute the adjustment structure.

[0009] As a further description of the above technical solution:

[0010] The third drive motor, rotating shaft, fixed ring, adjusting rod, and clamping plate constitute the screw clamp. There are two sets of fixed rings, and one side of the rotating seat is movably connected to a fixed ring.

[0011] As a further description of the above technical solution:

[0012] The second drive motor, the second slide, the slider, the rotating seat, the movable plate, and the spray head constitute the anti-rust spraying device. The water tank is equipped with a water pump. The angle and position of the anti-rust spraying device are adjustable.

[0013] As a further description of the above technical solution:

A collection groove is provided at the bottom of the shield. The baffles and the collection groove are on the same side.

[0015] As a further description of the above technical solution:

[0016] The number of support columns is four sets, and the bottom of each support column is provided with an anti-slip pad.

[0017] This utility model has the following beneficial effects:

[0018] This invention combines adjustability, automatic spraying, and ease of use to greatly improve the working efficiency of the screw processing fixture. While achieving the effect of clamping the screw, the device can adapt to the clamping requirements of screws of different sizes through the cooperation of the first drive motor, the threaded rod, and the slider. This avoids the problem that traditional fixtures can only clamp a single size, making it more convenient to use. In addition, the automated spraying effectively avoids contact between workers and rust inhibitors, reducing the harm caused by rust inhibitor odors or splashes on workers' skin.
