Abstract

A handle positioning device comprises a handle, a fixed sleeve, a sliding shaft, a screw, a spring, steel balls and a small spring, wherein a tube needs to be clamped, the handle is pushed to left, the sliding shaft is driven to rotate and move to left by the screw, and when the sliding shaft reaches a set position, the small spring in a through hole of the sliding shaft pushes the two steel balls to two ends, so that the steel balls just fall in an arch groove at the inner wall of the fixed sleeve so as to clamp the sliding shaft for positioning; and simultaneously, the spring pushing against the end surface of the fixed sleeve pushes the sliding shaft to left by an inner ring of a bearing, thereby enhancing clamping force for a cone frustum fixed on an outer ring of the bearing. When the tube is wound by yarn fully and needs to be unloaded, the handle is pushed to right, the inner wall of the fixed sleeve presses the steel balls on the sliding shaft into the through hole, and when the sliding shaft reaches the set position, under the thrust of the small spring, the steel ball 5 in the through hole 32 is bounced outwards and just clamps an arch step part of the end part of the fixed sleeve 2, and the cone frustum is pulled back to the position wherein the tube is loosened by the sliding shaft to be fixed. For the handle positioning device, the operation is simple, rapid and convenient, and the positioning time is shoter than one second.

Description

The handle registration device

Technical field

The utility model relates to the textile machine parts, relates to the handle registration device specifically.

Background technology

The rewinder that uses in the textile industry is all brought in from two and is clamped yarn spool-holder tube, prior art bobbin fixing device one end be driving wheel, can transmitting torque, but can not move, the other end is a follower, can move, and also can rotate on anchor shaft.In fixing device when work, require the bobbin rotation easily, and reliable clamping, gripping power are constant; When fixing device is deactivated, require simple and efficient to handle.Operative employee's groundwork is the bobbin that takes off around full yarn, changes bare bobbin, change frequency and reach hundreds of times of every day, and prior art bobbin fixing device complex structure, operational motion is loaded down with trivial details, tediously long, accumulates all day also time-consuming many.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of convenient to operation, reliable clamping, stable handle registration device are provided.

The present invention is achieved by following technical proposals:

The handle registration device comprises handle, fixed cover, slide shaft, screw, spring, steel ball, little spring; Axially be provided with an oval hole on the described fixed cover, be provided with the semi-round groove of a circle on the fixed cover inwall, fixed cover is not held and is provided with step on the inwall one, step and the semi arch transition of inwall joint.Be provided with a screw on the described slide shaft, the bonded assembly screw passes oval hole on the fixed cover and the oval hole on the handle on the screw, also is provided with a through hole on the slide shaft vertically.Placed a little spring in the slide shaft through hole, a steel ball has respectively been placed at the little spring two ends, and the length of little spring is enough to the steel ball at two ends is ejected through hole, exposes half steel ball at least.Overlapping a spring on slide shaft, spring one end heads on the fixed cover end face, and the other end heads on the bearing inner ring end face that is fixed on the axle.The handle, at its lower end pin joint can be swung along straight pin on straight pin, and the handle middle part is provided with an oval hole, and the width in oval hole and the screw external diameter that is fixed on the slide shaft are adaptive.

The utility model has the advantages that: be exactly fixing device enter mode of operation or the state of deactivating all need only one pushes away and gets over, last less than a second, move simple can't be few again.And mechanism is very simple so cleverly, and is estimable especially.

Description of reference numerals:

1 handle, 11 horizontal oval holes, 12 straight pins, 2 fixed covers, 21 perpendicular oval holes, 22 semi-circular recesses, 23 semi arch steps, 3 slide shafts, 31 screws, 32 through holes, 4 springs, 5 steel balls, 6 little springs, 7 frustums of a cone.

The specific embodiment

Further set forth the utility model below in conjunction with embodiment and accompanying drawing:

To handle registration device shown in Figure 6, comprise handle 1, fixed cover 2, slide shaft 3, spring 4, steel ball 5, little spring 6 as Fig. 1.Describe in detail below in conjunction with actual mechanical process, the operation of handle registration device is very simple, when needing to clamp bobbin, handle 1 pushes away toward the first from left, handle 1 is around straight pin 12 swings of lower end, drive slide shaft 3 toward moving left by screw 31, when arriving desired location, the little spring 6 that slide shaft 3 through holes are 32 li is two steel balls 5 are released to two ends, just in time drop on 22 li of the semi-circular recesses of fixed cover 2 inwalls, block slide shaft 3 location, the spring 4 that heads on fixed cover 2 end faces is simultaneously turned left slide shaft 3 by bearing inner ring and is pushed away, for the frustum of a cone 7 that is fixed on the outside race has increased gripping power, assist steel ball 5 to be stuck in the fixed form of 22 li of semi-circular recesses, increased reliability of positioning and run stability more.

On the bobbin when full yarn need unload, handle 1 is turned right and one is pushed away, fixed cover 2 inwalls are the 5 past 32 li pressures of through hole of the steel ball on the slide shaft 3, when slide shaft 3 arrives desired location, under the thrust of little spring 6, the steel ball 5 that through hole is 32 li ejects outward, just in time blocks semicircle step 23 places of fixed cover 2 ends, and slide shaft 3 is withdrawn into the position of unclamping bobbin to the frustum of a cone 7 and has fixed.
