Description

A tool for assisting the clamping of small workpieces with magnetic bases

technical field

The invention relates to a tool for assisting the clamping of a small workpiece magnetic base.

Background technique

In the process of die wire cutting, it is often necessary to process smaller workpieces. At this time, the magnetic base is used as an auxiliary tool for clamping operations. At present, in the wire cutting operation, the screw platen and the support seat are used to assist in fixing the magnetic seat, thereby fixing the workpiece to be processed.

When the above method is used for processing operations, a large number of screw pressure plates and support bases are occupied. When fixing the magnetic base, the height of the support base needs to be adjusted continuously, and the operation is time-consuming and laborious; Shaking will affect the processing accuracy of the workpiece. If it is pressed tightly, it will easily cause damage to the magnetic base, and even cause the workpiece in processing to be scrapped.

According to another embodiment of the present invention, it further includes that two horizontal screw holes are arranged symmetrically on the outer wall of the groove on the same horizontal plane; two vertical screw holes are arranged symmetrically On the outside wall of the groove at the same level.

According to another embodiment of the present invention, it further includes that the first tooling body is further provided with a pressure plate bolt, and the pressure plate bolt passes through a round hole and fastens the first tooling body on the machine tool through two nuts.

According to another embodiment of the present invention, it further includes that the insulating sheet is a stainless steel insulating sheet.

Beneficial effects: According to the length and height of the workpiece to be processed, it is judged that the clamping direction of the magnetic base is horizontal or vertical, and after determination, the second tooling body is respectively placed on the three surfaces where the magnetic base and the first tooling body are in contact, so as to achieve Magnetic resistance effect. If the magnetic base is placed horizontally, put the tooling body and the magnetic base into the groove of the first cuboid, select the vertical screw hole and press and fix it with countersunk screws; if the magnetic base is placed vertically, put it into the second cuboid groove In the groove, select the horizontal screw hole and press and fix it with the countersunk head screw. By setting the third cuboid groove and round hole, the rear end round hole under the first tooling body is aligned with the round hole of the beam of the machine tool, insert the pressure plate bolts that match the round hole into the round hole, and use two nuts to The upper and lower parts of the bolts are screwed in and tightened, so that the first tooling body and the magnetic base are firmly clamped on the machine tool beam. After the clamping is completed, the tooling body and the magnetic base can assist in fixing the workpiece to be processed for processing.

Detailed ways

As shown in Figures 1 and 2, a tooling for assisting the clamping of a small workpiece magnetic base includes a first tooling body 1 and a second tooling body 2, the first tooling body 1 is an irregular Z-shaped metal block, The front end of the first tooling body 1 is provided with a first rectangular parallelepiped groove 101 and a second rectangular parallelepiped groove 107; the first rectangular parallelepiped groove 101 is a groove arranged horizontally, and the outer wall of the groove on its top is opened There is a vertical screw hole 103 for fixing the magnetic base 3; the second rectangular parallelepiped groove 107 and the first rectangular parallelepiped groove 101 are vertically intersected with each other, and there are holes for fixing the magnetic base 3 on the outer wall of the groove on its side. Horizontal screw holes 102; two flat screw holes 102 are arranged symmetrically on the outer wall of the groove on the same horizontal plane; two vertical screw holes 103 are arranged on the grooves on the same horizontal plane symmetrically on the outer wall. The bottom of the rear end below the first tooling body 1 is provided with a third cuboid groove 104 adapted to the width of the machine tool beam, and the third cuboid groove 104 is embedded on the machine tool beam; the lower rear end of the first tooling body 1 There is a round hole 105 with the same diameter as the round hole on the crossbeam of the machine tool at the center; a pressure plate bolt 106 is also provided on the first tooling body 1, and the pressure plate bolt 106 passes through the round hole 105 to fasten the first Tooling body 1 is on the machine tool.

The second tooling body 2 is composed of three insulating sheets, the three insulating sheets are respectively placed on the three surfaces of the magnetic base 3 in contact with the tooling body 1, and the insulating sheets are stainless steel insulating sheets.

During use, according to the length and height of the workpiece to be processed, it is judged that the clamping direction of the magnetic base 3 is horizontal or vertical. The three surfaces of a tooling body 1 in contact with each other can achieve the effect of magnetic resistance. If the magnetic base is placed horizontally, put the tooling body 2 and the magnetic base into the first cuboid groove, and select the vertical screw hole 103 to be pressed and fixed by countersunk screws; if the magnetic base is placed vertically, put the second In the rectangular parallelepiped groove, select the horizontal screw hole 103 to be pressed and fixed by the countersunk head screw. Embed the third cuboid groove 104 at the bottom of the rear end of the first tooling body 1 on the machine beam, so that the round hole 105 at the rear end of the first tooling body 1 is aligned with the round hole of the machine tool beam, and will be matched with the round hole 105 The pressure plate bolt 106 is inserted into the round hole 105, and two nuts are used to screw in and tighten from the upper and lower parts of the bolt, so that the first tooling body 1 and the magnetic base 3 are firmly clamped on the machine tool beam. After the clamping is completed, the tooling body and the magnetic base can assist in fixing the workpiece to be processed for processing.

After the present invention is practical, the use of the screw press plate and the support seat can be avoided, and the time for adjusting the height of the support seat can be saved, so that the magnetic base 3 can be clamped in one step, saving time and labor; avoiding the magnetic base 3 from being clamped too loosely or too tightly, ensuring Workpiece processing accuracy, to avoid workpiece scrapping.

It should be understood that the specific embodiments described above are only used to explain the present invention, not to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
