Description

Technical Field

[0001] The utility model relates to the technical field of magnetic material cutting, in particular to a magnetic material cutting fixture. Background Art

[0002] Magnetic materials are usually made of brittle materials, such as NdFeB, etc. These materials are prone to breakage when subjected to external forces. During the cutting process, ensuring that the magnet is firmly fixed to reduce its movement and external forces can reduce the risk of breakage.

[0003] However, when processing tubular workpieces, the commonly used fixing methods have poor fixing effects on tubular workpieces. The workpieces may break or have insufficient processing accuracy due to factors such as the workpiece's own shaking during cutting and the collision with the cutting tool, thus affecting the quality of the finished workpiece. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0005] When processing tubular workpieces, the commonly used fixing methods have poor fixing effects on tubular workpieces. The workpieces may break or have insufficient processing accuracy due to factors such as the workpiece's own shaking during cutting and the collision with the cutting tool, thus affecting the quality of the finished workpiece.

[0006] In order to solve the problems existing in the prior art, the utility model provides a magnetic material cutting fixture, including a processing frame, a support plate is provided on the surface of the processing frame, a limiting rod is provided on the top of the support plate, a spring is provided on the outer side of the limiting rod, a pressure plate is provided at the end of the spring, and rubber pads are provided on the opposite sides of the pressure plate and the support plate, a hinge is provided on the surface of the processing frame, a C-shaped clamp is provided on the surface of the hinge, a rotating shaft is provided on the top of the C-shaped clamp, and a fixing bolt is provided on the surface of the rotating shaft.

[0007] The utility model provides a magnetic material cutting fixture.

[0008] Furthermore, four limiting rods are arranged on the surface of the support plate, and the limiting rods are arranged in groups of two and are arranged on both sides of the support plate respectively.

[0009] Furthermore, there are two pressing plates, and both ends of each pressing plate are respectively sleeved on the outside of a group of limiting rods.

[0010] Furthermore, both ends of the spring are respectively connected to the supporting plate and the pressing plate and the spring is always kept in a compressed state.

[0011] Furthermore, an arc-shaped groove is provided on the surface of the rubber pad.

[0012] Furthermore, both ends of the C-shaped clamp are provided with horizontal extension parts, and the hinge is connected to the C-shaped clamp through the bottom extension part.

[0013] Furthermore, there are two C-shaped clamps arranged facing each other, wherein the end of the extension part at the top of the C-shaped clamp on one side is provided with a rotating shaft, and the extension part at the top of the C-shaped clamp on the other side is provided with a groove adapted to the fixing bolt.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model uses a spring to pull the pressure plate close to the support plate to form a vertical pressure to restrict the tubular workpiece in the vertical direction. The C-shaped clamp can be rotated by the hinge during use, and the circular space formed between the two C-shaped clamps can restrict the workpiece in the horizontal direction, so that the workpiece can be restricted in the vertical and horizontal directions during processing, and in the process of placing the workpiece, it can be inserted into the C-shaped clamp through the pressure plate in the direction of the support plate and connected to the two C-shaped clamps as a whole through fixing bolts. The overall process is simple and fast. During the processing of the workpiece, one end of the C-shaped clamp is completely fixed, and the vibration is gradually transmitted to the end. The rubber pad in direct contact with the workpiece can greatly reduce the vibration of the end of the workpiece, avoiding the workpiece from being broken due to its own vibration during the cutting process. The overall structure is quick and convenient to use and has stable clamping. The suitable C-shaped clamp can also be selected according to the diameter of the workpiece.
