Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a small workpiece clamping mechanism for a wire-feeding machine. Background Art

[0002] Wire-cut, also known as low-speed wire-cut, uses a continuously moving thin metal wire (called electrode wire, generally copper wire) as an electrode to perform pulse spark discharge on the workpiece, generating a high temperature of more than 6000 degrees, etching the metal and cutting it into a workpiece. The principle of wire-cut processing is the phenomenon of continuous discharge to remove metal in the gap between the wire electrode and the workpiece. When performing wire-cut processing, a fixture is needed to fix both ends of the product. When dealing with processed products of different lengths, it is difficult for the fixture to make accurate positioning. The existing small workpiece clamping mechanism of the wire-cut machine is difficult to fix thinner or smaller workpieces, and its scope of application is narrow. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the problem that the existing small workpiece clamping mechanism of the wire-cutting machine is difficult to fix thinner or smaller workpieces and has a narrow application range.

[0004] The technical solution adopted to solve the above technical problems is:

[0005] A small workpiece clamping mechanism for a wire-cutting machine comprises a base plate, a side baffle, a clamping plate, a pressure plate and a pad, and is characterized in that: the pad is arranged in the middle of the upper end of the base plate, and the small workpiece to be clamped is placed in the middle of the pad so that one side of the small workpiece rests on the side baffle, and then the first cylinder box is controlled by a controller to work, and the first cylinder box drives the clamping plate to move so that the clamping plate is against the right side of the small workpiece to fix it laterally. Since there is a movable gap between the clamping plate and the pad, the clamping plate can fix thinner workpieces, and then the movable rod is pushed so that the pressure plate is pressed on the workpiece to fix it vertically, and then the movable rod is pushed to press the pressure plate on the workpiece to fix it vertically. The set screws are used to fix the movable rod on the connecting sleeve. The lateral fixation and the vertical fixation are combined with each other, so that the workpiece can be fixed more firmly and can adapt to the fixation of smaller-sized workpieces. The side baffle is provided on the left side of the pad, and the first cylinder box is provided on the right side of the pad. The first cylinder box is provided with a first telescopic rod, and the clamping plate is welded to the end of the first telescopic rod. A connecting sleeve is provided in front of the pad, and a movable rod is provided on the connecting sleeve. A movable groove is opened at the back of the connecting sleeve, and a connecting rod is welded on the inner side of the movable rod. The connecting rod passes through the movable groove, and the pressure plate is welded to the lower end of the connecting rod.

[0006] As a preferred technical solution of the utility model, mounting holes are provided around the base plate to facilitate installation.

[0007] As a preferred technical solution of the present invention, a controller is provided on the left outer side of the side baffle, and control buttons are provided on the controller.

[0008] As a preferred technical solution of the utility model, a row of fixing holes is opened on the front of the connecting sleeve, and set screws are provided on the fixing holes to facilitate fixing the movable rod on the connecting sleeve.

[0009] As a preferred technical solution of the utility model, a movable gap is left between the clamping plate and the pad, the outer side of the clamping plate is wrapped with a rubber film, and the right side of the side baffle is affixed with a rubber film.

[0010] As a preferred technical solution of the utility model, a second cylinder box is provided on the left side of the base plate, and a second telescopic rod is provided on the second cylinder box.

[0011] As a preferred technical solution of the utility model, a lighting lamp board is provided on the top of the second telescopic rod, and lighting lamp beads are provided on the lighting lamp board to provide lighting during processing.

[0012] The beneficial effects of the utility model are:

[0013] Since the utility model is provided with a base plate, a side baffle plate, a clamping plate, a pressure plate and a pad, a small workpiece to be clamped is placed in the middle of the pad so that one side of the small workpiece is against the side baffle plate, and then the first cylinder box is controlled to work by a controller, and the first cylinder box drives the clamping plate to move so that the clamping plate is against the right side of the small workpiece to fix it laterally. Since a small movable gap is left between the clamping plate and the pad, the clamping plate can fix thinner workpieces, and then the movable rod is pushed so that the pressure plate is pressed on the workpiece to fix it vertically, and then the movable rod is fixed to the connecting sleeve by a set screw. The combination of horizontal fixation and vertical fixation can fix the workpiece more firmly and can adapt to the fixation of smaller-sized workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] exist Figure 1-4The utility model provides a technical solution: a small workpiece clamping mechanism for a wire-cutting machine, comprising a base plate 1, a side baffle plate 7, a clamping plate 5, a pressure plate 17 and a pad 6. A pad 6 is provided in the middle of the upper end of the base plate 1. The small workpiece to be clamped is placed in the middle of the pad 6, so that one side of the small workpiece is against the side baffle plate 7, and then the first cylinder box 3 is controlled to work by the controller 18. The first cylinder box 3 drives the clamping plate 5 to move, so that the clamping plate 5 is against the right side of the small workpiece to fix it laterally. Since there is a movable gap between the clamping plate 5 and the pad 6, the clamping plate 5 can fix a thinner workpiece, and then the movable rod 11 is pushed so that the pressure plate 17 is pressed on the workpiece to fix it. It is fixed vertically, and then the movable rod 11 is fixed on the connecting sleeve 14 by means of the set screws 12. The lateral fixation is combined with the vertical fixation, so that the workpiece can be fixed more firmly and can adapt to the fixation of smaller-sized workpieces. A side baffle 7 is provided on the left side of the pad 6, and a first cylinder box 3 is provided on the right side of the pad 6. A first telescopic rod 4 is provided on the first cylinder box 3, and a clamping plate 5 is welded to the end of the first telescopic rod 4.

A movable groove 15 is opened at the back of the connecting sleeve 14, and a connecting rod 16 is welded on the inner side of the movable rod 11. The connecting rod 16 passes through the movable groove 15, and a pressure plate 17 is welded to the lower end of the connecting rod 16.

[0026] In one aspect of this embodiment, a controller 18 is provided on the left outer side of the side baffle 7, and a control button 19 is provided on the controller 18 to facilitate the operation of the device.

[0027] In one aspect of this embodiment, a lighting panel 8 is provided on the top of the second telescopic rod 10 , and lighting beads 9 are provided on the lighting panel 8 , which can provide lighting in a dark environment.

[0028] The working principle of the utility model is as follows: a small workpiece to be clamped is placed in the middle of the pad 6 so that one side of the small workpiece rests on the side baffle 7, and then the first cylinder box 3 is controlled to work by the controller 18, and the first cylinder box 3 drives the clamping plate 5 to move so that the clamping plate 5 is against the right side of the small workpiece to fix it laterally. Since there is a movable gap between the clamping plate 5 and the pad 6, the clamping plate 5 can fix thinner workpieces, and then the movable rod 11 is pushed so that the pressure plate 17 is pressed on the workpiece to fix it vertically, and then the movable rod 11 is fixed to the connecting sleeve 14 by the set screw 12. The combination of horizontal fixation and vertical fixation can fix the workpiece more firmly and can adapt to the fixation of smaller-sized workpieces.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
