When performing CNC precision machining on this type of workpiece 1, it is necessary to manually clamp the products one by one on the CNC clamping fixture, and the clamping time is relatively long. Especially because its product volume is small, affected by the unstable factors of people, the entire processing process becomes longer, the efficiency of the machine tool is unstable, and too much manpower is invested, resulting in a higher labor cost.

[0003] In the prior art, a Chinese invention patent with the application number 201210537334.3 discloses a magazine-type automatic loading device, which relates to an automatic loading device.

The present invention can be matched with various types of automatic assembly machines, automatic screen printing machines, and part processing machines, and solves the problem that, compared with manual loading, the production efficiency can be increased by more than twice, and the labor can be reduced by more than half.

[0004] The above patent drives the screw to rotate through the servo motor to drive the sliding bracket to rise so as to drive the parts to rise. However, for the workpiece in this application, due to its complex structure and small product volume, the above technical structure is not applicable. Content of the Utility Model

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example

[0025] See attached Figure 2 , 3 As shown, an anti-gravity anti-skid clip fixture includes a clip block 2, a contoured slider 3, a magnet 4, a limit pin 5 and a pneumatic component (not shown in the figure).

[0026] The clip block 2 is a long block structure, and a contour cavity 21 penetrating the clip block 2 is provided on the clip block 2 along its length direction, and the contour cavity 21 matches the shape of the workpiece 1, that is, the size of the workpiece 1 is slightly smaller than the size of the contour cavity 21, so that the workpiece 1 can slide in the contour cavity 21. Furthermore, in order to improve the feeding efficiency and the loading quantity, two contour cavities 21 are provided on the clip block 2, and the two contour cavities 21 can be placed symmetrically with respect to the center.

[0027] Further, in order to prevent the workpiece 1 from being placed upside down in the vertical direction when it is placed into the profiling cavity 21 from the upper opening of the profiling cavity 21, anti-fooling pins 22 matching the shape of the workpiece 1 can be fixedly embedded on the inner wall of the profiling cavity 21 at the upper opening of each profiling cavity 21 according to the specific shape of the workpiece 1.

[0028] In order to prevent the profiling slider 3 and the workpiece 1 from falling out of the lower opening of the profiling cavity 21, a limit pin 5 passing through the profiling cavity 21 is fixedly connected to the cartridge block 2 at the lower opening of each profiling cavity 21. Further, in order to facilitate the disassembly of the limit pin 5, the limit pin 5 is threadedly connected to the cartridge block 2 and passes through the profiling cavity 21.

[0029] See Figure 4 As shown, a profiling slider 3 matching the shape of the profiling cavity 21 is slidably embedded in the profiling cavity 21. The size of the profiling slider 3 is slightly smaller than the size of the profiling cavity 21, so that while the profiling slider 3 can slide smoothly in the profiling cavity 21, when the pneumatic component ventilates into the profiling cavity 21, it can not only push the profiling slider 3 to rise but also avoid excessive gas from escaping through the gap between the profiling slider 3 and the inner wall of the profiling cavity 21. A magnet 4 is embedded on the end face of the profiling slider 3 facing the inner side of the profiling cavity 21, and the magnet 4 can be adsorbed on the inner wall of the profiling cavity 21, that is, the cartridge block 2 is made of a metal material that can be adsorbed by the magnet 4.

[0030] The profiling cavity 21 below the profiling slider 3 is connected to a pneumatic component (not shown in the figure). The pneumatic component can be existing structures such as an air pump and a gas storage tank. The pneumatic component can introduce a specified volume of gas into the profiling cavity 21 to lift the profiling slider 3. In actual use, the cartridge block 2 can be detachably placed on an existing sealing plate to seal the lower opening of the profiling cavity 21. The pneumatic component can introduce gas into the profiling cavity 21 through a pipe joint embedded in the sealing plate and connected to the profiling cavity 21, or can also introduce gas into the profiling cavity 21 through a pipe joint embedded in the cartridge block 2 below the profiling slider 3.

[0031] See Figure 2 As shown, in order to facilitate the taking and placing of the cartridge block 2, a handle 23 is fixedly connected to the outer end face of the cartridge block 2 at the upper end of the profiling cavity 21 by bolts.

[0032] See Figure 5 As shown, the magnet 4 is a cylindrical structure. An embedding hole 31 is formed in the profiling slider 3, and the magnet 4 is embedded in the embedding hole 31. The inner diameter of the embedding hole 31 is larger than the outer diameter of the magnet 4, so that the magnet 4 can move slightly in the embedding hole 31, which can ensure that the magnet 4 and the inner wall of the profiling cavity 21 are in full contact to generate the maximum adsorption force.

[0033] Further, a conical hole 32 is provided at the bottom of the inlay hole 31, or the inlay hole 31 penetrates through the profiling slider 3, and a bottom hole 33 penetrating through the profiling slider 3 is provided at the bottom of the inlay hole 31. A conical structure or a hollow structure is required at the bottom of the inlay hole 31, so that the adsorption force between the inner surface of the magnet 4 and the profiling slider 3 is less than the adsorption force between the outer surface of the magnet 4 and the inner wall of the profiling cavity 21. After the profiling slider 3 is placed, the magnet 4 can be directly adsorbed on the inner wall of the profiling cavity 21, so that the maximum adsorption force is generated between the magnet 4 and the inner wall of the profiling cavity 21. In this embodiment, two inlay holes 31 are arranged perpendicular to each other. The bottom of one inlay hole 31 is a conical structure, that is, a conical hole 32 is provided, and the other inlay hole 31 penetrates through the profiling slider 3, that is, a bottom hole 33 is provided.

[0034] The working principle and process of the present utility model are as follows:

[0035] Continuously press a plurality of workpieces 1 into the profiling cavity 21 from the upper opening of the profiling cavity 21 until the profiling slider 3 moves to abut against the limit pin 5 and then stop putting in the workpieces 1;

[0036] Hold the handle 23 and place the magazine 2 with the workpiece 1 on the sealing plate to seal the lower opening of the profiling cavity 21. Then, pass a required volume of gas, such as air, into the profiling cavity 21 below the profiling slider 3 through the pneumatic assembly to lift the profiling slider 3. After it reaches the specified height, close the air source. Since the magnet 4 is adsorbed on the inner wall of the profiling cavity 21, the frictional force between the magnet 4 and the inner wall of the profiling cavity 21 is greater than the gravity of the profiling slider 3 and the workpiece 1 thereon. Therefore, the profiling slider 3 can stop at any position inside the profiling cavity 21, thus realizing automatic feeding.

[0037] The profiling slider 3 of the anti-gravity anti-slip magazine fixture counteracts the downward gravity of the workpiece 1 under the adsorption action between the magnet 4 and the inner wall of the profiling cavity 21, preventing the profiling slider 3 from sliding down under the influence of gravity. The anti-gravity anti-slip magazine fixture is simple to operate and has a low failure rate during use. During the debugging process, only the weight of the workpiece in the profiling cavity 21 and the resistance generated by the magnet 4 adsorbing on the inner wall surface of the profiling cavity 21 need to be evaluated, so that the resistance can overcome the gravity of the workpiece and prevent it from sliding down.

[0038] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
