Abstract
The utility model discloses a self-locking device of a feeding roll wire-drawing machine, comprising a gear seat, a gear, set blocks, set bolts, compression springs and steel balls; wherein, the inner end surface of the gear leans against the gear seat and is capable of do circular motion at the gear seat; the set blocks are fixed at the outer end surface of the gear; installation holes of the compression springs are arranged at the set blocks and the gear; a plurality of taper holes are correspondingly arranged at the gear seat; the number of the taper holes is the same as the number of teeth of a ratchet wheel; the set bolts press the compression springs and the compression springs press the steel balls; when the gear moves, the gear closely clings to the taper holes in the gear seat to realize location; the device comprises two sets of set blocks, two sets of set bolts, two sets of compression springs and two sets of steel balls which are in circle center symmetrical distribution at the outer end surface of the gear; and the elasticity of the compression springs is adjusted by screwing in or screwing out the set bolts. The beneficial effects are as follows: the existing grinding roller wire-drawing machines can be transformed into the feeding roll wire-drawing machines, so that the cost is low, the manufacturing is convenient and the manufacturing cycle is short and the production bottleneck is solved in time.
Description
Technical field
The utility model relates to a kind of self-locking device of machining equipment, particularly a kind of self-locking device of feeding roller wire drawing machine.
Technical background
Feeding roller is the same with grinding roller, all is parts commonly used in the food mechanical equipment, and the hackly surface wire drawing all will be carried out usually in its surface, and is as shown in Figure 1, and the zigzag wire drawing is 91, and these wire drawings all are that axially parallel distributes along the feeding roller surface usually.
Existing feeding roller wire drawing machine comes through the grinding roller wire drawing machine transformation of the way usually, but the grinding roller wire drawing machine usually the diameter wire drawing scope of processing and when processing the feeding roller of general diameter below 200mm, the entanglement of surperficial wire drawing striped can appear all more than 200mm.
The reason that the entanglement of above-mentioned wire drawing striped occurs is that the worm transmission pair of existing grinding roller wire drawing machine is the single head self-locking; In order to change a social system the feeding roller of the stretching footpath of ability, must to change the worm transmission pair of grinding roller wire drawing machine into four-head, just can reach the wire drawing fringe number requirement of feeding roller less than 200mm; But because lead angle is too big; The self-locking performance that has surpassed worm screw, thus can't realize self-locking, so processed feeding roller surface wire drawing entanglement just can occur.
The utility model content
The technical problem that the utility model will solve provides a kind of self-locking device of feeding roller wire drawing machine, to overcome in the prior art feeding roller wire drawing machine that come by the transformation of the way of the grinding roller wire drawing machine wire drawing entanglement problem because of can't self-locking producing.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of self-locking device of feeding roller wire drawing machine; Comprise pinion stand, gear, fastening block, holding screw, compression spring, steel ball; Its middle gear inner face leans on pinion stand and can on pinion stand, move in a circle, and gear is fixed with fastening block on the outer face, and the compression spring mounting hole is arranged on fastening block and the gear; On the pinion stand to some taper holes should be arranged; The quantity of taper hole is consistent with the ratchet number of teeth, and holding screw is pushed down the compression spring, the compression spring is pushed down steel ball, is close to through steel ball in the gear movement and realizes the location in the taper hole of pinion stand.
Especially, said taper hole quantity is preferred 10.
Especially, said fastening block and holding screw, compression spring, steel ball have two groups, on the gear outer face, are the center of circle and are symmetrically distributed.
Especially, the elastic force size of said compression spring is screwed or is unscrewed through holding screw and regulates.
During equipment work, ratchet is stirred ratchet, the ratchet driven gear, and gear driven worm screw rotation calibration because steel ball under the effect of spring force, is positioned on the taper hole of pinion stand, can not thrown off; When ratchet is stirred ratchet once more, the ratchet driven gear, its power surpasses the spacing sliding wiping power of steel ball, drives the accurate calibration of worm screw effectively, so the wire drawing striped can entanglement.
The beneficial effect of the self-locking device of the described feeding roller wire drawing machine of the utility model is: can directly utilize existing grinding roller wire drawing machine equipment reform to become the feeding roller wire drawing machine; Only need when worm transmission pair changes four-head into; Append the self-locking device of the utility model; Cost is lower, easy to make like this, the input fabrication cycle is short, has in time solved the production bottleneck phenomenon.

The specific embodiment
Like Fig. 2 to shown in Figure 4, be the utility model feeding roller wire drawing machine self-locking device stereochemical structure, master's TV structure when self-locking device is spacing, along the A-A cross-sectional view.
A kind of self-locking device of feeding roller wire drawing machine; Comprise pinion stand 1, gear 2, fastening block 3, holding screw 4, compression spring 5, steel ball 6; Its middle gear 2 inner faces lean on pinion stand 1 and can on pinion stand 1, move in a circle, and gear is fixed with fastening block 3 on 2 outer faces, and compression spring 5 installing holes are arranged on fastening block 3 and the gear 2; On the pinion stand 1 to some taper holes 11 should be arranged; The quantity of taper hole 11 and hook tooth number average are 10, and holding screw 4 is pushed down compression spring 5, compression spring 5 is pushed down steel ball 6, are close in the taper hole 11 of pinion stand 1 through steel ball 6 in gear 2 motion and realize the location.
Said fastening block 3 and holding screw 4, compression spring 5, steel ball 6 have two groups, on gear 2 outer faces, are the center of circle and are symmetrically distributed.
The elastic force size of said compression spring 5 is screwed or is unscrewed through holding screw 4 and regulates.
During equipment work, ratchet is stirred ratchet, and ratchet driven gear 2, gear 2 drive worm screw rotation calibration, because steel ball 6 under the effect of spring force, is positioned on the taper hole 11 of pinion stand 1, can not throw off; When ratchet is stirred ratchet once more, ratchet driven gear 2, its power surpasses the spacing sliding wiping power of steel ball 6, drives the accurate calibration of worm screw effectively, so the wire drawing striped can entanglement.
