Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1 to 2, a guide bar assembly of an engine camshaft with a suction function according to a preferred embodiment of the present invention includes: guide rod 1, circular location nail 2, pin 5 and magnet 4. The guide rod 1 is of a cylindrical structure. The round positioning nail 2 is arranged at the center of the front end face of the guide rod 1, a groove 3 is formed in the front end face of the guide rod 1, and the magnet 4 is embedded in the groove 3. The pin 5 is provided at a position near the edge of the front end face of the guide rod 1, and is arranged to be positioned by fitting into a hole of the end face of the camshaft with the circular positioning pin 2. Preferably, two grooves 3 are symmetrically arranged on the front end surface of the guide rod 1 at two sides of the circular positioning nail 2. Two magnets 4 are embedded in two grooves 3 respectively, and magnets 4 are used for effectively adsorbing the guide rod assembly on the end face of the camshaft, so that the matching tightness is improved.
In one embodiment of the invention, the recess 3 is a cylindrical recess having a diameter of 10cm and a depth of 20 cm. The magnet 4 is a cylindrical magnet, and the height of the magnet 4 is less than (slightly less than) 20cm, so that the magnet 4 cannot be exposed out of the front end face of the guide rod 1, but stable adsorption can be ensured.
In one embodiment of the invention, the pin 5 and the round positioning pin 2 are 5cm higher than the front end surface of the guide rod 1, the guide rod is difficult to pull out due to too long pin, and the positioning is inaccurate and is easy to loosen due to too short pin.
