Embodiment Construction

[0025] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] Such as figure 1 , figure 2 Shown, a kind of pushing type indexing mechanism, it comprises indexing mechanism body 5, and the ratchet 3 that is installed on the indexing mechanism body 5, movable cylinder 1 and spring lifting block;

[0027] The ratchet 3 is fixedly connected with the movable rod of the movable cylinder 1, and moves under the drive of the movable rod, and four pulleys 14 are evenly installed along the circumference on the ratchet 3;

[0028] The top of the spring lifting block is against the pulley 14, and the extrusion of the spring lifting block by the pulley 14 moves up and down of the spring lifting block.

[0029] Preferably, as figure 1 As shown, the indexing mechanism body 5 is also equipped with a pawl 4 for prev...

Abstract

The invention discloses a push type dividing mechanism. The push type dividing mechanism comprises a dividing mechanism body, as well as a ratchet wheel, a movable cylinder and a spring lifting block, which are mounted on the dividing mechanism body; the ratchet wheel is fixedly connected with a moving rod of the moving cylinder and moves under the drive of the moving rod; a plurality of pulleys are uniformly mounted on the ratchet wheel along the circumference; the top end of the spring lifting block is propped against the pulleys, and the pulleys extrude the spring lifting block to control the spring lifting block to move up and down. According to the push type dividing mechanism disclosed by the invention, with the adoption of the push-pull action of a conventional moving cylinder and with the cooperation of the ratchet wheel with the pulleys, one-time rotary dividing is finished; directional rotation stop is performed on the ratchet wheel through a pawl, so that the ratchet wheel only can rotate clockwise; through changing the quantity of the pulleys and the one-time travel of the moving cylinder matched with the pulleys in quantity, a rotation angle of the ratchet wheel during each-time dividing is simply and conveniently changed; the push type dividing mechanism is simple in structure, low in machining cost and more convenient for position control.

Description

technical field [0001] The invention relates to a push-type indexing mechanism, which belongs to the technical field of indexing mechanisms. Background technique [0002] At present, in some fixture design structures that require indexing processing, many of them use manual or electric indexing, and the structure is also commonly used in the fixed type, ratchet type, gear or worm gear type. Among these indexing transmission structures, the manual structure has low efficiency and low precision; the electric structure has a large position control cost and a long machining cycle. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a push-type indexing mechanism with simple structure and simple operation. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a push-type indexing mechanism, which includes an in...
