Description

Technical Field

[0001] The utility model relates to the technical field of cam seats, in particular to a combined cam seat. Background Art

[0002] A cam refers to a mechanical rotating or sliding part (such as a wheel or a protruding part of a wheel) 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. The cam follower mechanism can be designed to meet almost any input-output relationship within its range of motion, and the cam seat is a connecting part between the camshaft and the cam. The cam seat is usually mounted on the camshaft to support the cam and enable it to rotate.

[0003] In the prior art, the cam seat is usually processed as an integral part. For example, the patent application with the authorization publication number CN211820629U and the authorization publication date 2020-10-30, entitled "A Highly Wear-Resistant Cam Seat", includes a mounting groove, and the upper and lower ends of the mounting groove are respectively fixed with upper and lower blocks; although the cam seat has a stable structure, when a certain part of the cam seat is damaged, the entire cam seat cannot be used normally, which is not conducive to the development of the enterprise and is not convenient for the subsequent rapid installation of the cam.

[0004] Therefore, we propose a combined cam seat to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The purpose of the utility model is to provide a combined cam seat to solve the problems in the current market raised by the above background technology.

[0009] A locking assembly is installed at the upper end of the upper mounting member, and the upper mounting member is connected and fixed to the lower mounting ring through the locking assembly.

[0010] Furthermore, the upper mounting member is composed of a first ring body and a second ring body, a connecting groove is reserved between the first ring body and the second ring body, and the connecting groove is fitted to the inner and outer walls of the upper end of the lower mounting ring.

[0011] Through the above technical solution, the upper mounting member and the lower mounting ring are connected.

[0012] Furthermore, the locking assembly includes a locking bolt threadedly mounted on the upper mounting member, and a nut and a positioning column are respectively installed at both ends of the locking bolt, and the middle portion of the locking bolt passes through the interior of the upper end of the lower mounting ring.

[0013] Through the above technical solution, the locking bolt can subsequently drive the pressing block to extend into the lower mounting ring.

[0014] Furthermore, a pressing block is provided on the outer threaded sleeve of the middle part of the locking bolt, and the pressing block slides in close contact with the inside of the first ring body, and the upper end of the pressing block on one side close to the lower mounting ring is designed to be inclined.

[0015] Through the above technical solution, the top pressure block can be pressed together with the lower mounting ring on one side, so that the locking bolt can be threadedly rotated into the top pressure block, and under the continuous pressing action, the locking bolt can drive the top pressure block to move.

[0016] Furthermore, one end of the pressing block close to the lower mounting ring fits inside the pressing groove, and the pressing groove is opened inside the upper end of the lower mounting ring, and the height of the pressing groove is greater than the height of the pressing block.

[0017] Through the above technical solution, the top pressure block drives the lower mounting ring to move upward during the movement, so that the upper seat body and the lower seat body are closely fitted to the cam, thereby realizing the rapid installation of the cam.

[0018] 3. Beneficial effects:

[0019] The technical solution provided by the utility model is adopted. Compared with the prior art, the combined cam seat of the utility model is composed of an upper seat body and a lower seat body, so that when a part is damaged, the corresponding part can be replaced, which reduces the production cost and is faster to install. The specific contents are as follows:

[0020] The cam is then pressed against the outer surface of the camshaft and the cam is then pressed against the outer surface of the camshaft, and the cam is pressed against the outer surface of the camshaft and the cam is then pressed against the outer surface of the camshaft.
