Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to a multifunctional fixture. Background Technology

[0002] In the existing technology, fixtures fix the workpiece for machining. The shapes of the workpieces are diverse, so the structures of the fixtures are also diverse. In order to meet the needs of different workpieces and for economic reasons, different types of fixtures are also required.

[0003] Among numerous existing technologies, Chinese patent application CN102049690A discloses a self-positioning fixture, which includes a U-shaped frame, a lifting device, and a clamping device. The lifting device includes a screw, a nut, two push rods, and a push rod seat. One end of the screw is fixed to the center of the frame. The push rod seat is a bushing with two crossbars symmetrically fixed on both sides. The bushing is fitted onto the screw. Each side of the frame has a through hole, and the two push rods are located in the through holes. The two crossbars are respectively connected to the lower ends of the two push rods. The clamping device includes two clamping blocks and two rotating levers. The two clamping blocks are respectively fixed to the upper ends of the two push rods. Each clamping block is hinged to one end of the rotating lever, and the other end of the rotating lever is hinged to the upper part of both sides of the frame.

[0004] However, the limiting function in this patented technology is only applicable to clamping workpieces of a specific shape, and the single-station processing makes the clamping effect unstable for workpieces of different shapes and sizes.

[0005] Based on this, the present invention designs a multifunctional clamp to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multifunctional clamp.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multifunctional clamp includes a magnetic base metal plate. The upper end of the magnetic base metal plate is equipped with four sets of multi-station adsorption components for adjusting the position to adapt to the product size. The spacing between the two sets of multi-station adsorption components on the left is equal to the spacing between the two sets of multi-station adsorption components on the right. The side end of each multi-station adsorption component is equipped with a positioning clamping component for rotating and adjusting the angle for positioning and clamping.

[0009] Furthermore, the multi-station adsorption assembly includes a magnetic clamp and a rotating handle; the magnetic clamp is adsorbed onto the upper surface of the metal plate of the magnetic base, and there are four sets of magnetic clamps. The magnetic clamps are connected to the positioning and clamping assembly, and a rotating handle is fixedly installed on the upper end of the magnetic clamp.

[0010] Furthermore, the spacing between the two sets of magnetic clips on the left is equal to the spacing between the two sets of magnetic clips on the right, and the spacing between the two sets of magnetic clips on the front is equal to the spacing between the two sets of magnetic clips on the rear.

[0011] Furthermore, the positioning and clamping assembly includes a clamping plate, a cam, and a rubber sheet; the side end of the clamping plate is rotatably connected to the rotating end of the magnetic clamp, the clamping plate is in contact with the side wall of the cam, the cam is fixedly connected to the rotating end of the magnetic clamp, and a groove is provided on the side of the clamping plate away from the magnetic clamp, with a rubber sheet fixedly installed at the bottom of the groove.

[0012] Furthermore, the lower end of the clamp is slidably connected to the magnetic base metal plate.

[0013] Furthermore, the groove is configured as a triangle.

[0014] Furthermore, the positioning and clamping assembly also includes a pin; the lower part of the pin is threadedly connected to the clamping plate, and the inside of the rubber sheet has a through-hole for sliding with the pin.

[0015] Furthermore, the upper end of the pin is configured as a hemispherical shape.

[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. When this utility model is used, the four sets of multi-station adsorption components can perform multi-station processing on four sets of workpieces. At the same time, the number of multi-station adsorption components placed on the magnetic base metal plate can be changed according to the number of workpieces to be processed. The distance can be changed by moving the multi-station adsorption components, the clamping angle can be changed by rotating the positioning clamping components, and then the multi-station adsorption components and the positioning clamping components can be fixed to adapt to workpieces of different shapes and position the workpieces, so as to realize the fixed clamping of processed products of different shapes and sizes.

[0017] 2. When using this utility model, if it is necessary to change the spacing between the magnetic clips, rotate the handle. The handle drives the rotating end of the magnetic clip to rotate. When the handle rotates 30 degrees clockwise, the magnetic module inside the magnetic clip changes to a different type of magnetic attraction, causing its bottom to disengage from the magnetic base metal plate. Manually adjust the position of the magnetic clip, and then rotate the handle in the opposite direction to generate magnetic force so that the magnetic clip is fixedly attracted to the current position, which is suitable for workpieces of different sizes. The magnetic clip in the current fixed position can clamp rectangular workpieces.

[0018] 3. When using this utility model, the workpiece is placed on the rubber sheet. The friction of the rubber sheet prevents the workpiece from sliding during processing. The clamping plate diagonally clamps the four corners of the workpiece. When it is necessary to adjust the angle of the clamping plate, the handle is rotated 30 degrees clockwise. The handle drives the cam to rotate, causing the clamping plate to disengage from the cam. At the same time, the rotation of the handle puts the magnetic clamp in a non-magnetic state. At this time, rotating the clamping plate changes the corresponding angle of the groove. Rotating the handle counterclockwise again causes the handle to drive the cam to rotate and contact the clamping plate, fixing the current position of the clamping plate. At the same time, the magnetic clamp is put into a magnetic state, realizing synchronous positioning of products of different shapes.

[0019] 4. When using this utility model, the pins further position the workpiece and are inserted into the corresponding opening positions of the workpiece to achieve clamping and fixation, preventing displacement. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A multifunctional clamp includes a magnetic base metal plate 1. The upper end of the magnetic base metal plate 1 is equipped with four sets of multi-station adsorption components 2 for adjusting the position to adapt to the product size. The distance between the two sets of multi-station adsorption components 2 on the left is equal to the distance between the two sets of multi-station adsorption components 2 on the right. The side end of the multi-station adsorption components 2 is equipped with a positioning clamping component 3 for rotating and adjusting the angle for positioning and clamping.

[0031] When this utility model is used, the four sets of multi-station adsorption components 2 can perform multi-station processing on four sets of workpieces. At the same time, the number of multi-station adsorption components 2 placed on the magnetic base metal plate 1 can be changed according to the number of workpieces to be processed. The distance can be changed by moving the multi-station adsorption components 2, and the clamping angle can be changed by rotating the positioning clamping component 3. Then, the multi-station adsorption components 2 and the positioning clamping component 3 are fixed to adapt to workpieces of different shapes and position the workpieces, so as to realize the fixed clamping of processed products of different shapes and sizes.

[0032] The multi-station adsorption assembly 2 includes a magnetic clip 21 and a rotating handle 22; the magnetic clip 21 is adsorbed onto the upper surface of the magnetic base metal plate 1, and there are four sets of magnetic clips 21. The magnetic clip 21 is connected to the positioning and clamping assembly 3, and the rotating handle 22 is fixedly installed on the upper end of the magnetic clip 21. The model of the magnetic clip 21 is Magswitch magnetic clip.

[0033] When using this utility model, if it is necessary to change the spacing between the magnetic clips 21, rotate the handle 22. The handle 22 drives the rotating end of the magnetic clip 21 to rotate. When the handle 22 rotates 30 degrees clockwise, the magnet module inside the magnetic clip 21 changes to a different type of magnetic attraction, causing its bottom to disengage from the magnetic base metal plate 1. Manually adjust the position of the magnetic clip 21, and then rotate the handle 22 in the opposite direction to generate magnetic force so that the magnetic clip 21 is fixedly attracted to the current position, which is suitable for workpieces of different sizes.

[0034] The spacing between the two sets of magnetic clips 21 on the left is equal to the spacing between the two sets of magnetic clips 21 on the right, and the spacing between the two sets of magnetic clips 21 on the front is equal to the spacing between the two sets of magnetic clips 21 on the rear.

[0035] When this utility model is in use, the magnetic clamp 21 at the current fixed position can clamp the rectangular workpiece.

[0036] The positioning and clamping assembly 3 includes a clamping plate 31, a cam 32, and a rubber sheet 33; the side end of the clamping plate 31 is rotatably connected to the rotating end of the magnetic clamp 21, the clamping plate 31 is in contact with the side wall of the cam 32, the cam 32 is fixedly connected to the rotating end of the magnetic clamp 21, a groove 34 is provided on the side of the clamping plate 31 away from the magnetic clamp 21, and the rubber sheet 33 is fixedly installed at the bottom of the groove 34; the lower end of the clamping plate 31 is slidably connected to the magnetic base metal plate 1; the groove 34 is triangular.

[0037] In use, the workpiece is placed on the rubber sheet 33. The friction of the rubber sheet 33 prevents the workpiece from sliding during processing. The clamping plate 31 clamps the four corners of the workpiece diagonally. When it is necessary to adjust the angle of the clamping plate 31, the handle 22 is rotated 30 degrees clockwise. The handle 22 drives the cam 32 to rotate, causing the clamping plate 31 to disengage from the cam 32. At the same time, the rotation of the handle 22 puts the magnetic clamp 21 in a non-magnetic state. At this time, rotating the clamping plate 31 changes the corresponding angle of the groove 34. Rotating the handle 22 counterclockwise again causes the handle 22 to drive the cam 32 to rotate and contact the clamping plate 31, fixing the current position of the clamping plate 31. At the same time, the magnetic clamp 21 is put in a magnetic state, realizing synchronous positioning of products of different shapes.

[0038] The positioning and clamping assembly 3 also includes a pin 35; the lower part of the pin 35 is threadedly connected to the clamping plate 31, and the inside of the rubber 33 is provided with a through-hole for sliding with the pin 35; the upper end of the pin 35 is set as a hemispherical shape.

[0039] When this utility model is used, the pin 35 further positions the workpiece and is inserted into the corresponding opening position of the workpiece to achieve clamping and fixation and prevent displacement.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
