Abstract

Hook cam mechanism up and down, including toothed disc, cam of rising to the bait, lower hook cam, rise to the bait yoke fork and lower hook fork.Described lower hook cam and cam of rising to the bait are separately fixed at two sides before and after toothed disc.One end of lower hook fork is arranged on before toothed disc and moves along the contour line of lower hook cam.The yoke end of yoke fork of rising to the bait is connected with cam of rising to the bait and moves up and down along the contour line of cam of rising to the bait.This utility model simple in construction, drives the transmission simultaneously of two cams by toothed disc, utilizes the change of cam profile, achieves two actions, working stability with a set of mechanism, and transmission efficiency is high, and is greatly saved manufacture and maintenance cost.

Description

Hook cam mechanism up and down

Technical field

This utility model is a kind of hook cam mechanism up and down of a kind of cam drive, especially making fishing net machine, belongs to In mechanical field.

Background technology

Have knot fishing net netting machine during knitmesh, need hook plate, lower hook son move simultaneously make fishing lines knotting and Break off relations.Current fishing net machine to realize this kinestate, needs two set motions to synchronize to carry out, such frame for movement just than More complicated, and inefficiency, safeguard and manufacturing cost is the highest.

Utility model content

For above-mentioned the deficiencies in the prior art, this utility model provides high upper and lower of a kind of simple in construction, work efficiency Hook cam mechanism.

For achieving the above object, the technical solution adopted in the utility model is: hook cam mechanism up and down, including toothed disc, Rise to the bait cam, lower hook cam, rise to the bait yoke fork and lower hook fork.Described lower hook cam and cam of rising to the bait are separately fixed at tooth Two sides before and after wheel disc.One end of lower hook fork is arranged on before toothed disc and moves along the contour line of lower hook cam.On The yoke end of hook yoke fork be connected with cam of rising to the bait and along cam of rising to the bait contour line move up and down.

Preferably, the drive pinion engaged with toothed disc is also included.

Preferably, also include through the center of toothed disc and fix the power transmission shaft being connected with toothed disc.

This utility model simple in construction, drives the transmission simultaneously of two cams by toothed disc, utilizes the change of cam profile Changing, achieve two actions, working stability with a set of mechanism, transmission efficiency is high, and is greatly saved manufacture and maintenance cost.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

As Figure 1-Figure 5: hook cam mechanism up and down, including toothed disc 1, power transmission shaft 5, cam 4 of rising to the bait, lower hook cam 7, Drive pinion 6, rise to the bait yoke fork 2 and lower hook fork 3.Described drive pinion 6 engages with toothed disc 1.Described lower hook Cam and cam of rising to the bait are separately fixed at two sides before and after toothed disc.Power transmission shaft 5 through toothed disc 1 center and with toothed disc 1 Fixing connection.One end of lower hook fork 3 is arranged on before toothed disc and moves along the contour line of lower hook cam 7.Rise to the bait fork The yoke end of arm fork 2 be connected with cam 4 of rising to the bait and along cam 4 of rising to the bait contour line move up and down.

Rotated by driven by motor drive pinion, thus on driven gear dish rise to the bait cam and lower hook cam turns simultaneously Dynamic.Lower hook fork does wobbling action along the contour line of lower hook cam, can drive lower hook son's action by bindiny mechanism；Rise to the bait fork Arm fork swings along with the contour line of cam of rising to the bait, and can drive upper hook plate action by bindiny mechanism, thus by a set of machine Structure achieves hook plate, lower hook son moves simultaneously, to help netting machine to realize the knotting action of fishing net.

Claims

1. upper and lower hook cam mechanism, it is characterised in that: include toothed disc, cam of rising to the bait, lower hook cam, rise to the bait yoke fork and under Hook fork；Described lower hook cam and cam of rising to the bait are separately fixed at two sides before and after toothed disc, and one end of lower hook fork sets Putting before toothed disc and move along the contour line of lower hook cam, the yoke end of yoke fork of rising to the bait is connected with cam of rising to the bait And along the contour line up and down motion of cam of rising to the bait.

2. hook cam mechanism up and down as claimed in claim 1, it is characterised in that: also include the little tooth of transmission engaged with toothed disc Wheel.

3. hook cam mechanism up and down as claimed in claim 1, it is characterised in that: also include the center through toothed disc and tooth The power transmission shaft of connection fixed by wheel disc.
