[0020] Next, the technical solutions in the embodiments of the application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the application. In addition, "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0021] It should also be noted that in this article, relative terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such article or terminal device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the article or terminal device including the element.

[0022] In the field of mechanical production and processing technology, raw materials are placed in processing equipment in a specified form. In order to fix the materials, special fixtures are often used to clamp the materials. The clamped materials are not only convenient for positioning but also for feeding. However, existing clamping devices all push the materials from multiple directions to a preset position, which not only requires multiple driving devices, but also the amount of clamped materials is not compatible, that is, a fixture under one structure can only clamp materials of one specification size; moreover, the multi-point positioning method is not convenient for material calibration and increases the calibration pressure. Therefore, a new automatic fixture is urgently needed to solve the drawbacks of existing fixtures.

The limiting plate includes a first limiting plate 61 and a second limiting plate 62. The slide bar 2 is arranged at the bottom of the base 1 along the extending direction of the base 1. After one end of the L-shaped pressing bar 3 is hinged to a slider, the slider is slidably connected to the slide bar 2. The pressing block 4 is arranged parallel to the base 1. After the L-shaped pressing bar 3 rotates to the pressing position, the other end of the L-shaped pressing bar 3 matches with the pressing block 4 to apply pressure to the pressing block 4. The first limiting plate 61 and the second limiting plate 62 are oppositely arranged on both sides of the base 1. The correction mechanism includes a push rod 51 and a first driver.

Wherein, a toothed structure is arranged at the force application end of the L-shaped pressing bar 3, and the pressing block 4 includes a plurality of hollow structures, and the toothed structure is adapted to the hollow structures.

[0024] As Figure 1 and Figure 2 shown, the utility model provides an automatic fixture device, which includes a base 1, a slide bar 2, an L-shaped pressing bar 3, a pressing block 4, a correction mechanism and a limiting plate. The first limiting plate 61 and the second limiting plate 62 are respectively arranged on both sides of the base 1.

The correction mechanism includes a push rod 51 and a first driver. After the first driver abuts against the push rod 51, the first driver pushes the first limiting plate 61 and / or the second limiting plate 62 to move for correcting the material. In addition, a toothed structure is arranged at the force application end of the L-shaped pressing bar 3, and the pressing block 4 includes a plurality of hollow structures, and the toothed structure is adapted to the hollow structures, which increases the stability of the force application at the force application end and also increases the uniformity of the force application. In the utility model, the material can be flexibly pressed and fixed from one direction, and materials with different stacked thicknesses can be fixed at one time, thereby increasing the compatibility, stability and practicability of the fixture.

[0025] It should be noted that, as Figure 2 shown, the pressing block 4 is arranged to include a hollow structure, so that the toothed structure on the L-shaped pressing bar 3 matches the hollow part to increase the stability of the pressing block 4 under force.

[0026] There are two L-shaped pressing bars 3. Among them, the force application end of one L-shaped pressing bar 3 is sleeved with the pressing block 4.
