Description

Technical Field

[0001] This utility model relates to the field of camshaft processing equipment, specifically to a cam opening device to prevent detachment. Background Technology

[0002] A cam is a rotating or sliding component in a machine that transmits motion to a roller moving close to its edge or a needle bar moving freely on a groove surface, or it receives force from such rollers and needle bars. Cam follower mechanisms can be designed to satisfy input-output relationships within their range of motion. For some applications, cams and linkage mechanisms can serve the same purpose, and both can be used. From a working perspective, cams are easier to design than linkage mechanisms, and cams can do many things that linkage mechanisms cannot. On the other hand, cam mechanisms are easier to manufacture than linkage mechanisms. However, existing cam opening devices lack protective devices above the box, making it easy for dust and debris to enter, causing contamination of the friction surface and increasing wear. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a cam opening device that prevents detachment. The main body of the cam opening device is covered by a cover to protect the internal structure. At the same time, the hydraulic rod on the moving block can lift the cover by telescopic movement. Then, the screw on the base can be rotated to move the threaded moving block, making it easy to open the cover and facilitate maintenance by the staff. The hydraulic rod on the outer hinge of the cover is telescopically connected to the inner hinge of the hydraulic rod. The hinge of the hydraulic rod drives the fixed frame to adjust the angle, and the fan on the fixed frame absorbs the air near the through hole of the cover, reducing the entry of dust and debris.

[0004] This utility model also provides a cam opening device with the above-mentioned anti-detachment mechanism, comprising: a main body of the anti-detachment cam opening device, a base fixedly connected to the outer surface of the main body, a lead screw rotatably connected to the outer surface of the base, a moving block threadedly connected to the outer surface of the lead screw, a hydraulic rod one fixedly connected to the upper surface of the moving block, a fixing plate fixedly connected to the output end of the hydraulic rod one, a cover fixedly connected to the outer surface of the fixing plate, a hinge one fixedly connected to the outer surface of the cover, a hydraulic rod two hinged to the inner wall of the hinge one, a hinge two hinged to the output end of the hydraulic rod two, a fixing frame fixedly connected to the outer surface of the hinge two, a fixing hole provided on the outer surface of the fixing frame, and a fan rotatably connected to the inner wall of the fixing hole.

[0005] According to the present invention, a cam opening device for preventing detachment is provided, wherein the lower surface of the cover covers the main body of the cam opening device, and the outer surface of the cover is provided with a through hole, thereby effectively covering the main body of the cam opening device and protecting the internal mechanism from the influence of the external environment.

[0006] According to the present invention, a cam opening device for preventing detachment is provided inside the main body of the cam opening device. The outer surface of the cam opening device is movably connected to the through hole. The movable connection of the cam opening device allows it to swing flexibly, thereby enhancing the operational flexibility of the device.

[0007] According to the present invention, in the cam opening device for preventing detachment, the outer surface of the cover is hinged to the fixing frame, and the fan is located outside the through hole. The fan's position outside the through hole improves the fan's ability to absorb air near the through hole of the cover, which helps to reduce the entry of dust and debris.

[0008] According to the present invention, a cam opening device for preventing detachment is provided, wherein a guide rod is fixedly connected to the inner side of the base, and the outer surface of the guide rod is slidably connected to the moving block. The slidable connection between the guide rod and the moving block ensures smooth sliding, reduces friction and wear, and thus extends the service life.

[0009] According to the present invention, a cam opening device for preventing detachment is provided, wherein one end of the lead screw is fixedly connected to a handle, and the other end of the lead screw is rotatably connected to the main body of the cam opening device for preventing detachment. The handle design of the lead screw makes it easier to operate, and users can easily adjust the movement of the moving block, thereby improving the user experience.

[0010] According to the present invention, a cam opening device for preventing detachment is provided, wherein a connector is fixedly connected to the outer surface of the base, and a threaded hole is provided on the upper surface of the connector. The connector provides a stable basic structure, ensuring that the connection of the entire device is firm and not easy to loosen.

[0011] According to the present invention, in a cam opening device for preventing detachment, the lower surface of the hinge is fixedly connected to the fixed plate, and the lower surface of the moving block is slidably connected to the base. The sliding connection design between the moving block and the base makes the operation smoother and reduces resistance and wear during operation.

[0012] This utility model protects the internal structure by covering the main body of the anti-fall-off cam opening device with a cover. At the same time, the hydraulic rod on the moving block can lift the cover by telescopic movement, and the screw on the base can be rotated to move the threaded moving block, making it easy to open the cover and make it convenient for staff to maintain.

[0013] The hydraulic rod 2, which is hinged to the inner side of the outer hinge of the cover, extends and retracts, causing the hinge 2, which is hinged to the hydraulic rod 2, to drive the fixed frame to adjust its angle. This allows the fan on the fixed frame to absorb air near the through hole of the cover, reducing the entry of dust and debris. Attached Figure Description
