Description

Technical Field

[0001] The invention relates to the technical field of rubber processing knives, in particular to a handheld rubber burr processing knife. Background Art

[0002] Rubber products refer to various rubber products produced with natural and synthetic rubber as raw materials, such as rubber sealing rings, sealing gaskets, etc. Rubber products usually have burrs on their edges after processing. In order to ensure the quality of rubber products, the burrs of the rubber need to be processed.

[0003] Existing rubber burr processing equipment generally uses a person holding a rubber burr processing knife to clean the burrs on the edges of rubber products. This method saves costs and is not restricted by the shape of the product and can remove burrs on products of any shape. However, this method still has certain defects: when the person holds the processing knife, the hand is unstable and the processing knife cannot be pushed horizontally to maintain the fit effect on the rubber. Summary of the invention

[0004] The purpose of the present invention is to provide a handheld rubber burr processing knife to solve the problem in the prior art proposed in the above background technology that when a person holds the processing knife, his hand is unstable and he cannot maintain the fit effect on the rubber when pushing the processing knife horizontally.

[0005] To achieve the above object, the present invention provides the following technical solution: a handheld rubber burr treatment knife, comprising a knife body,

[0006] A hand grip sleeve is installed on the outside of the tool body, a cutter head body is connected to the top of the tool body through a thread, an inclined cutter head is installed on the top of the cutter head body, a mounting ring is also installed on the outside of the tool body, a rotating mounting part is rotatably installed on both sides of the mounting ring, and a guide frame is installed on the top and bottom of the rotating mounting part;

[0007] The guide frame includes guide rod 1 and guide rod 2, and roller 1 is rotatably installed on the top of guide rod 1 and guide rod 2. Two clamping plates are installed on the top of guide rod 1 and guide rod 2. Guide plates are provided at the bottom of the clamping plates, and the guide plates are inserted into the sliding grooves opened on the tops of guide rod 1 and guide rod 2.

[0008] By adopting the above technical solution, when in use, the person holds the hand grip on the tool body and moves the whole body so that the inclined cutter head is close to the edge of the rubber product. When the inclined cutter head is in contact with the edge of the rubber, the roller one on the top of the guide rod one and the guide rod two is also in contact with the edge of the rubber, and the rolling design of the roller one facilitates lateral movement. The design of the splint facilitates the upper and lower positions between the cutter head body and the rubber to avoid upper and lower deviations during lateral movement.

[0009] As a further solution of the present invention: the hand grip sleeve is designed to be arc-shaped, and an anti-slip ring is provided at the end of the hand grip sleeve.

[0010] By adopting the above technical solution, when in use, a person holds the grip cover with his / her hand, and the anti-drop ring and the limit plate at the bottom of the grip cover can prevent the grip cover from falling out of the hand.

[0011] As a further solution of the present invention: a mounting hole is opened inside the mounting ring, and a threaded hole is opened on the mounting ring, the mounting ring is fixed to the outside of the tool body by positioning bolts, and a magnetic component 1 is installed on the top and bottom of the rotating mounting part, and the magnetic component 1 is located on the outside of the guide rod 1 and the guide rod 2.

[0012] By adopting the above technical solution, when in use, the mounting ring can be removed from the tool body by removing the positioning bolt.

[0013] As a further solution of the present invention: mounting rods are fixedly mounted on both sides of the mounting ring, and a rotatable rotating mounting part is rotatably mounted on the outer side of the mounting rods, and the ends of the mounting rods are threadedly connected with fixing nuts.

[0014] By adopting the above technical solution, when in use, the cooperation between the mounting rod and the fixing nut can make the rotatable mounting part fixed after being rotated. When it is necessary to replace different guide frames to both sides of the cutter head body, the rotatable mounting part can be flipped by loosening the fixing nut and then rotating the rotatable mounting part so that the guide frame at the bottom of the rotatable mounting part faces upward.

[0015] As a further solution of the present invention: a double-threaded screw is rotatably installed in the slide groove at the top of the guide rod one and the guide rod two, and the two sections of thread on the double-threaded screw are respectively threadedly connected with the threaded holes on the two guide plates. A guide column is also installed in the slide groove, and the guide column passes through the two clamping plates.

[0016] By adopting the above technical solution, when in use, through the design of the double-threaded screw, the two guide plates can drive the clamping plates to move closer to or away from each other, thereby being able to adapt to rubber products of different thicknesses.

[0017] As a further solution of the present invention: rollers 2 are rotatably mounted on the side walls of the clamping plate that are close to each other.

[0018] By adopting the above technical solution, when in use, the design of the second roller can reduce the friction during the overall lateral movement.

[0019] As a further solution of the present invention: a limit plate is fixedly installed on both side walls of the tool body, the limit plate is located between the hand grip sleeve and the mounting ring, two limit sliding grooves are opened on the outer side wall of the limit plate, and a protective box is slidably installed on the outer side of the limit plate.

[0020] By adopting the above technical solution, when in use, the guide frame below the rotating mounting part is protected by the limiting plate and the protective box, which can avoid collision and reduce the influence of the bottom guide frame on the hand grip of the personnel.

[0021] As a further solution of the present invention: the protective box includes a slide plate, the front and rear sides of the protective box are equipped with slide plates, and the slide plates are aligned with the limiting slide grooves, a bottom plate is installed at the bottom of the slide plate, and magnetic component 2 is installed on the top of the protective box and the slide plate.

[0022] By adopting the above technical solution, when in use, the protective box can be installed and disassembled by sliding the slide plate in the limit plate, and the magnetic component 2 can attract the magnetic component 1 on the mounting ring to achieve the adsorption of the protective box. When personnel need to replace the guide frame, they can first slide the protective box downward from the limit plate to expose the guide frame.

[0023] Compared with the prior art, the invention has the following beneficial effects: the handheld rubber burr treatment knife can

[0024] (1) A guide frame is provided. When the inclined cutter head is in contact with the side of the rubber product, the rollers 1 on the guide rod 1 and the guide rod 2 are in contact with the side of the rubber product. The upper and lower clamping plates are respectively located on the upper and lower sides of the rubber product to limit the longitudinal position of the guide rod 1 and the guide rod 2 to avoid upward and downward deviation during lateral movement, thereby providing a good guiding effect on the lateral movement and upward and downward position of the inclined cutter head.

[0025] (2) A mounting ring is provided. When the cutter head body is replaced to adapt to rubber products of different shapes, the rotating mounting portion on the mounting ring can be rotated and flipped, so that the guide frame on the other side is rotated to the two sides of the cutter head body, which has a guiding effect on the cutter head body, and the rotating mounting portion can be limited after flipping through the cooperation of the mounting rod and the fixing nut;

[0026] (3) A limit plate and a protective box are provided, and the limit plates and the protective box on both sides of the tool body cooperate with each other to shield the guide frame below the rotating mounting part, so as to prevent the unused guide frame from being hit, thereby affecting the accuracy of the guide frame.
