Abstract
The utility model discloses a clearance adjusting device for meshing the conjugate cam or the roller and pertains to a textile mechanical field. The utility model mainly solves the problems of adjusting the clearance between the conjugate cam and the roller and comprises two sets of clearance adjusting institution that is fixed within the cam box and each set of the clearance adjusting institution is composed of a roller that is arranged on one end of the pendulum shaft and is meshed with the actuating cam arranged on the principal axis and the other end of the pendulum shaft is arranged with a roller that is meshed with the follow up cam of the same principal axis. The utility model is characterized in that the roller meshed with the actuating cam is fixed on the end of the pendulum shaft via the pin roll while the roller meshed with the follow up cam is fixed on the end of the pendulum shaft via an eccentric pin roll. The utility model has the advantages of simple and convenient operation and that just rotating the eccentric pin roll can adjust the optimal meshing clearance between the conjugate cam and the roller.
Description
Technical field
The utility model relates to a kind of textile machine device, specifically is conjugate cam, the roller meshing gap adjusting mechanism that uses on the Rapier looms.
Background technology
Wefting insertion, beating-up mechanism are topmost two great institutions in the Rapier looms five big motions.Modern Rapier looms, the particularly wefting insertion of high speed Rapier looms, to beat up generally all be to utilize conjugate cam to realize.General wefting insertion, the transmission mechanism that beats up are formed by being sealed in a pair of conjugate cam in the left and right cam box, two groups of rollers and serial driving member.Two pairs of conjugate cams that are fixed on the same main shaft are controlled the large and small balance staff reciprocally swinging of driven member by roller respectively, and drivening rod, gear etc. come and go two strokes, realize wefting insertion, beat up.If conjugate cam and little balance staff roller back lash are excessive or too small, rare close shelves can appear in fabric, reduce product specification or make corresponding mechanism stressed excessive, damage parts; If conjugate cam is excessive or too small with big balance staff roller back lash, the weft yarn handing-over will be broken down.Therefore between conjugate cam and the roller optimal engagement gap be conjugate cam transmission wefting insertion, loom the next item up most important parameters of beating up.For guaranteeing the optimal engagement gap generally by selecting for use the close roller of diameter to match, this not only will process the close roller of a variety of diameters also will could realize that efficient is low, the cost height through repeated disassembled and assembled in the actual production.
Summary of the invention
For simplified manufacturing technique, assembly technology, to raise the efficiency, reduce cost, the utility model provides a kind of conjugate cam, roller meshing gap adjusting mechanism.
The technical solution of the utility model is achieved in that this kind conjugate cam, roller meshing gap adjusting mechanism, comprise the two cover gap guiding mechanisms that are fixed in the cam box, every suit clearance adjustment mechanism consists of, be arranged on the roller and the actuating cam engagement that is arranged on the main shaft of balance staff one end, roller that the other end of balance staff is provided with and the inverted cam engagement that is arranged on the same main shaft; It is characterized in that, be fixed on the end of balance staff with bearing pin, be fixed on the end of balance staff with eccentric pin shaft with the roller of inverted cam engagement with the roller of actuating cam engagement.
Earlier one group of roller is fixed on A1, the A2 place of (little) balance staff greatly, with eccentric pin shaft another group roller is fixed on B1, the B2 place of (little) balance staff greatly again, then main shaft, big balance staff, little balance staff etc. are fixed in the cam box with bearing pin.
Adjust the roller and the actuating cam engagement at big (little) balance staff A1, A2 place earlier, use spanner rotating eccentricity bearing pin again, adjust the optimal engagement gap between the inverted cam on big (little) balance staff B1, B2 place roller and the main shaft, back lash error between simultaneously rectifiable big (little) balance staff A1, A2 place roller and the actuating cam.Whole conjugation transmission mechanism cooperates miscellaneous part to finish wefting insertion, beating motion.This guiding mechanism is simple, convenient, and only need rotating eccentricity bearing pin just can adjust the optimal engagement gap between conjugate cam, the roller.
The utility model conjugate cam, roller meshing gap adjusting mechanism beneficial effect are:
By the rotating eccentricity bearing pin, adjust on big (little) balance staff optimal engagement gap between the roller and conjugate cam easily.Simple in structure, easy to operate.Simplify manufacturing technique, assembly technology, improved operating efficiency, reduced cost.

The specific embodiment
Earlier one group of roller 14 is fixed on the A1 place of big balance staff 16 by bearing pin 17 at Fig. 1, again another is organized roller 4 is fixed on big balance staff 6 by eccentric pin shaft 5 B1 place;
As Fig. 2, again one group of roller 24 is fixed on the A2 place of big balance staff 26 by bearing pin 27, again another group roller 24 is fixed on the B2 place of big balance staff 26 by eccentric pin shaft 25;
Then main shaft 3, big balance staff 16, little balance staff 26 etc. are fixed in the cam box.
Adjust the roller and the actuating cam engagement at A1, A2 place on big (little) balance staff earlier, use spanner rotating eccentricity bearing pin again, adjust the optimal engagement gap between the actuating cam on A1, A2 place roller and the main shaft 3 on the optimal engagement gap between the inverted cam on B1, B2 place roller and the main shaft 3 on big (little) balance staff, big (little) balance staff, cooperate miscellaneous part to finish wefting insertion, beating motion.
The utility model conjugate cam, roller meshing gap adjusting mechanism, the specific embodiment is very simple, big balance staff, little balance staff, main shaft, conjugate cam, roller, bearing pin, eccentric pin shaft can realize that by machining the utility model is a kind of advanced in performance, low-cost and conjugate cam, roller meshing gap adjusting mechanism simple to operate.
