Abstract
The utility model belongs to the technical field of numerically-controlled spring coiling machines, and mainly relates to a clamping mechanism for material-feeding rolling wheels of a numerically-controlled spring coiling machine. Rolling wheel clamping sleeves (1) are respectively arranged on the outer sides of upper material-feeding rolling wheels (2) and lower material-feeding rolling wheels (8) which are sleeved on an upper material-feeding shaft (3) and a lower material-feeding shaft (7) which are arranged in parallel; each rolling wheel clamping sleeve (1) is provided with an upper semi-circle and a lower semi-circle; the upper semi-circles of the rolling wheel clamping sleeves (1) are integrally connected with the material-feeding rolling wheels; and the lower semi-circles of the rolling wheel clamping sleeves are integrally connected with the upper semi-circles and tightly compress the material-feeding rolling wheel clamping sleeves on the material-feeding shafts. The clamping mechanism prevents the material-feeding rolling wheels of the numerically-controlled spring coiling machine from gradually producing axial displacement in a spring coiling process, prevents scratches on the material-feeding rolling wheels caused by the production of the axial displacement, and increases the yield of coiled springs.
Description
Technical field
The utility model belongs to Digital Control Plane Roll-up Spring machine technology field, relates generally to a kind of clamp mechanism of Digital Control Plane Roll-up Spring machine feeding roller.
Background technology
At present, several mounting means that the equal feeding roller of Digital Control Plane Roll-up Spring machine adopts upper and lower symmetry to install to the feeding roller, dispose three and go up feeding roller and three following feeding rollers, by feeding roller on the pressure steel wire is pressed to down the feeding roller, the rotation of upper and lower feeding roller moves forward steel wire and forms spring.For moving along straight line all the time, the steel wire that guarantees to be sent to requires then that three R shape line sending groove centers of going up feeding rollers and three following feeding rollers must to locate basal plane consistent with lathe.
The feeding roller structure of domestic and international Digital Control Plane Roll-up Spring machine, it is after the location dimension of the location dimension of feeding roller on several and several following feeding rollers is adjusted, with screw the feeding roller to be fixed on feed spool and the following feed spool respectively.But since upper and lower feed spool can not absolute parallel and the spring forming process in the axial thrust load that produces make upper and lower feeding roller overcome the fastening force of screw and produce gradually and move axially, the moving axially not only feed spool surface scratch but also cause the change in size that rolls spring to make the percent defective rising of feeding roller.
Summary of the invention
The purpose of this utility model is the clamp mechanism that proposes a kind of Digital Control Plane Roll-up Spring machine feeding roller, overcome Digital Control Plane Roll-up Spring machine feeding roller and in rolling the spring process, produce axial displacement gradually, prevent to cause the scratch of feeding roller shaft, improve the yield rate that rolls spring because of generation axial displacement.
The utility model is finished the technical scheme that its invention task taked:
A kind of clamp mechanism of Digital Control Plane Roll-up Spring machine feeding roller, feeding roller, the following feeding roller outside are respectively arranged with the roller gripping sleeve on being nested with on feed spool, the following feed spool on be arrangeding in parallel, described roller gripping sleeve is divided into upper and lower two semicircles, the upper semi-circle of roller gripping sleeve is connected one with the feeding roller, and the lower half circle of roller gripping sleeve is connected one and the feeding roller is clamped casing pressure tightly on feed spool with upper semi-circle.
The beneficial effects of the utility model are:
(1) make the Digital Control Plane Roll-up Spring machine in rolling of spring guaranteed each feeding roller in the process R shape wire casing center and lathe datum level consistent size and remain unchanged.
(2) guaranteed that the Digital Control Plane Roll-up Spring machine rolls the dimensional stability of spring, has improved product quality after adopting this mechanism.
(3) it is nearly 33% that each part feeding roller of feeding roller can be saved bearing steel, and the machining period that reduced machine simultaneously can be saved nearly 32 kilograms of bearing steel as one group of feeding roller of CSM-580CNC Digital Control Plane Roll-up Spring machine (six).

The specific embodiment
With embodiment the utility model is further specified in conjunction with the accompanying drawings:
As shown in Figure 1 and Figure 2, a kind of clamp mechanism of Digital Control Plane Roll-up Spring Digital Control Plane Roll-up Spring machine feeding roller is nested with three respectively and goes up feeding roller 2, following feeding rollers 8 on the last feed spool 3 that is parallel to each other, the following feed spool 7; Corresponding each go up feeding roller 2, time feeding roller 8 is provided with roller gripping sleeve 1 respectively, roller gripping sleeve 1 is upper and lower two semicircles, the upper semi-circle of roller gripping sleeve 1 is connected one by two soket head cap screws 9 with the feeding roller, after the size A1 of the size A that respectively three is gone up feeding roller 2 and three following feeding rollers 8 adjusts, the lower half circle of roller gripping sleeve 1 is connected one with upper semi-circle by soket head cap screw 10, simultaneously the feeding roller is clamped casing pressure tightly on feed spool, prevent that feeding roller 2, time feeding roller 8 from moving axially.
Claims (1)
1. the clamp mechanism of a Digital Control Plane Roll-up Spring Digital Control Plane Roll-up Spring machine feeding roller, it is characterized in that: the last feeding roller (2) that is nested with on feed spool on be arrangeding in parallel (3), the following feed spool (7), following feeding roller (8) outside are respectively arranged with roller gripping sleeve (1), described roller gripping sleeve (1) is upper and lower two semicircles, the upper semi-circle of roller gripping sleeve (1) is connected one with the feeding roller, and the lower half circle of roller gripping sleeve (1) is connected one and the feeding roller is clamped casing pressure tightly on feed spool with upper semi-circle.
