Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a module box clamp. Background Art

[0002] A module box, also known as a module box or modular storage box, is an outer box used to combine electronic components or other small items into modules for easy carrying and management. There are many types of module boxes, such as plastic module boxes, metal module boxes, and cardboard module boxes. When processing and manufacturing plastic module boxes and metal module boxes, clamping devices are required to fix them so that other processing equipment can perform other processing on the fixed module box workpiece.

[0003] There are two commonly used clamping methods for module boxes. One is to use a vise with aluminum jaws, on which a groove in the shape of the module box is machined, and then the vise is used to clamp the module box workpiece placed in the groove for processing; the other is to use the vacuum adsorption principle, using vacuum negative pressure to suck the back of the module box for processing, and then use an auxiliary pressure block to press it down. Among the above clamping methods, the vise clamping process takes a long time and is unstable. If the processing speed is too fast, it is easy to bounce off. The vacuum adsorption clamping is very troublesome to clamp, and the constant replacement of the pressure plate is tedious, which affects the overall processing time. In addition, it can generally only clamp one module box workpiece, which increases the processing time and production cost.

[0004] When clamping the existing module box, there is a problem that there is no fixture design that can quickly clamp the workpiece. For this reason, the present application proposes a module box fixture. Utility Model Content

[0005] The purpose of the present utility model is to provide a module box clamp to solve the problem of the lack of a clamp design for quickly clamping a workpiece proposed in the above background technology.

[0010] Preferably, the pressing frame is a three-dimensional isosceles trapezoidal structure, and a rectangular through hole is provided at the center of the pressing frame.

[0011] Preferably, a second groove and a sliding groove that are connected are provided on the surface of the fixture plate.

[0012] Preferably, a transmission member is provided on the surface of the moving block, which includes a connecting plate connected to the moving block at one end and a push block installed inside the second groove.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figures 1 to 5 The utility model provides a technical solution: a module box fixture, including a fixture plate 1, a module box mounting groove 11 and a first groove 13 are provided on the surface of the fixture plate 1, a clamping plate 12 is provided on the fixture plate 1 between the module box mounting groove 11 and the first groove 13, a vacuum interface 16 is provided on the fixture plate 1, and a conventional vacuum equipment is connected at the vacuum interface 16, which is beneficial to the vacuum negative pressure adsorption principle, and adsorbs the module box workpiece placed on the module box mounting groove 11. The vacuum negative pressure adsorption principle is a conventional technical means, and this application will not go into details. The clamping plate 12 is made of elastic metal material (such as spring steel), and there is a gap a and a gap b between the clamping plate 12 and the fixture plate 1. The clamping plate 12 is in flexible contact with the module box workpiece placed on the module box mounting groove 11. When the clamping plate 12 is subjected to pressure, the clamping plate 12 presses the module box workpiece When the locking cone 32 rotates, the locking cone 32 is spirally connected to the clamping plate 1, the locking cone 32 moves down and squeezes the moving block 31, and the moving blocks 31 on both sides move in opposite directions under the action of the locking cone 32, so that the pressing frame 33 presses against the clamping plate 12, and then presses the module box workpiece.

[0026] In this embodiment, a threaded column C is provided on the bottom surface of the locking cone column 32 and is threadedly connected to the clamp plate 1. The locking cone column 32 is fixedly connected to the clamp plate 1. The locking cone column 32 moves downward and squeezes the movable block 31. The movable blocks 31 on both sides move in opposite directions under the action of the locking cone column 32, thereby causing the clamping frame 33 to press against the clamping plate 12.

[0027] In this embodiment, the pressing frame 33 is a three-dimensional isosceles trapezoidal structure, and a rectangular through hole is provided at the center of the pressing frame 33. The pressing frame 33 is in surface contact with the clamping plate 12, and the pressing frame 33 has a large surface area for applying action on the clamping plate 12.

[0028] In this embodiment, a second groove 14 and a sliding groove 15 are provided on the surface of the clamp plate 1, and a transmission member is provided on the surface of the moving block 31. The transmission member includes a connecting plate 41 connected to the moving block 31 at one end, and a push block 42 installed inside the second groove 14. The push block 42 includes a slider, a connecting rod connected to the connecting plate 41 and the slider at both ends respectively, the connecting rod is welded to the slider, and the connecting rod is screwed to the connecting plate 41 by screws. The slider is a right-angled trapezoidal structure. When the moving block 31 moves, the connecting plate 41 and the push block 42 move in the same direction accordingly, and the push block 42 can push the clamping block 52 to move.

[0029] In this embodiment, the clamping plate 1 is located in the sliding groove 15 and is provided with a fixed frame 51. The fixed frame 51 is combined with the clamping plate 1 by conventional methods (such as screw connection). The internal sliding connection of the fixed frame 51 is provided with a clamping block 52. A ball 521 is provided on one end of the clamping block 52. The ball 521 is tangent to the inclined surface of the slider. A rolling body 511 is provided on the opposite inner side wall of the fixed frame 51, which is tangent to the outer surface of the clamping block 52. When the push block 42 moves, the push block 42 acts on the ball 521 at one end of the clamping block 52. Since the friction between the clamping block 52 and the rolling body 511 on the fixed frame 51 is small, the clamping block 52 is moved by the thrust of the push block 42, and the clamping block 52 clamps the module box workpiece in the module box mounting groove 11.

[0030] The working principle and use process of this utility model:

[0031] When clamping the module box workpiece mounted in the module box mounting groove 11 on the fixture plate 1, the locking cone 32 is inserted between the opposing moving blocks 31;

[0032] The locking cone 32 rotates and is screwed to the fixture plate 1. The locking cone 32 moves downward and squeezes the moving block 31. The moving blocks 31 on both sides move in opposite directions under the action of the locking cone 32, so that the pressing frame 33 presses against the clamping plate 12, thereby pressing the module box workpiece.

[0033] When the moving block 31 moves, the connecting plate 41 and the pushing block 42 move in the same direction;

[0034] When the push block 42 moves, the push block 42 acts on the ball 521 at one end of the clamping block 52, and the clamping block 52 is subjected to a thrust force;

[0035] The friction between the clamping block 52 and the rolling element 511 on the fixed frame 51 is small, and the clamping block 52 is moved by the thrust of the push block 42, and the clamping block 52 clamps the module box workpiece in the module box installation groove 11;

[0036] To sum up: the fixture of the present application can quickly clamp the workpiece, and the module box workpiece can be placed symmetrically in the module box mounting groove 11, which is conducive to vacuum adsorption for rapid fixation, and the locking cone column 32 is rotated, the moving block 31 and the clamping frame 33 move, and the clamping frame 33 is against the clamping plate 12, thereby pressing the module box workpiece. At the same time, the push block 42 moves and acts on the clamping block 52, and the clamping block 52 is subjected to the thrust of the push block 42 to clamp the module box workpiece.
