Description

Technical Field

[0001] This utility model relates to the field of dovetail rail positioning technology, specifically a dovetail rail positioning device. Background Technology

[0002] Bending machines are a very important tool in the current machining industry. They are bulky and inconvenient for workers to handle and move. In terms of driving power, commonly used sheet metal bending machines are generally divided into two categories: mechanical and hydraulic. Mechanical bending machines use an electric motor to move the worktable up and down through a series of gears and eccentric wheels, while hydraulic bending machines use hydraulic cylinders and a complete set of oil circuit control components. These bending machines play an important role in the mass production of large enterprises.

[0003] The dovetail rails of existing bending machines cannot achieve good self-positioning during positioning. To address this, we propose a dovetail rail positioning device. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0021] Please see Figure 1-6In this embodiment of the utility model, a dovetail rail positioning device includes a dovetail rail 1, a sliding seat 2, and a pad 3. The sliding seat 2 has a sliding groove 22, and the pad 3 is disposed in the sliding groove 22. The pad 3 is located above the dovetail rail 1, and the dovetail rail 1 slides in the sliding groove 22. The sliding seat 2 has a screw hole 24, and a screw for adjusting the pad 3 is installed at the screw hole 24 on the sliding seat 2. The pad 3 can be clamped by the screw, so that the pad 3 clamps the dovetail rail 1. At this time, the sliding seat 2 cannot slide on the dovetail rail 1, thus realizing the positioning function.

[0022] The dovetail rail 1 includes a dovetail rail body 11, which has a first inclined surface 12 and a chamfered structure 13 at the edge of the first inclined surface 12. The pad 3 includes a pad body 31, which has a second inclined surface 34 at the bottom that mates with the first inclined surface 12. The mate of the inclined surfaces facilitates the action of the pad 3 on the dovetail rail 1.
