Description

A kind of spanner for rotating tricot machine main shaft

Technical field

A kind of instrument for tricot machine is the utility model is related to, specifically a kind of spanner for rotating tricot machine main shaft.

Background technology

During the development, production and assembling and setting of tricot machine, it is often necessary to rotate main shaft.The side of main shaft was rotated in the past Method is usually directly to use hand rotating pulley, this method not only very sweat, and be difficult to be accurately positioned.The main shaft of tricot machine It is to control to one-directionally rotate by freewheel clutch, when practical operation can bring inconvenience to user of service.Another method It is the very little row transmission mechanism carried using tricot machine, defect is that speed is excessively slow.The scientific research personnel of vast tricot machine and production line Skilled worker, it is all highly desirable to have that a kind of operation is easy, easy to use, effect accurately specific purpose tool, easily to solve The rotational positioning problem of tricot machine main shaft, while easy to the quiet moment of torsion of measurement main shaft.

The content of the invention

During to overcome existing tricot machine to install and debug the problem of rotation spindle action trouble, the utility model provides a kind of Rotate the spanner of tricot machine main shaft.

To solve its technical problem, the technical solution adopted in the utility model is：A kind of rotate that the program is designed passes through The spanner of owner's axis is compiled, including：Overcoat, roller, inner sleeve, clamp ring, baffle ring and lever, its feature are：

The 1st, the freewheel clutch of roller is installed between the overcoat and inner sleeve, and be fixed on by inner sleeve and clamp ring On main shaft；And be that overcoat is machined with equally distributed 3 ~ 4 wedge grooves along around its endoporus, active configuration has roller in wedge groove, The angle of wedge of each wedge groove is consistent along the direction of overcoat endoporus circumference, and the angle of wedge is 3 ~ 6 °, it can be ensured that is rolled when being pulled along main axis direction Column is non-slip, and roller slips easily over inner sleeve when reversely pulling；

2nd, the quantity of the rolling element, that is, roller is corresponding with the quantity of wedge groove consistent, and 3 roller configurations will to machining accuracy Ask lower, each roller stress is than more uniform, but 4 roller configurations easily make structure configuration more compact；

3rd, for the normal use and service life of guarantee spanner, the case hardness of contact surface between overcoat, roller, inner sleeve HRC≥60；

Compared with prior art, the utility model has following features and progress：Since the utility model is equipped with multiple rollings For column similar to the spanner of freewheel clutch, which is that overcoat is machined with equally distributed 3 ~ 4 wedges along around its endoporus Groove, active configuration has roller in wedge groove, difference is put on inside with the wedge groove processing of general freewheel clutch, in use, passing through Inner sleeve and clamp ring are fixed on main shaft, then back and forth pull fixed lever on the coat, can more easily rotate main shaft；Due to Can back and forth pull by a small margin, thus it is easy to implement be accurately positioned, with more the property of ergonomics；At the same time it can also convenient Ground measures Spindle Static moment of torsion, not only accurate positioning, but also during measurement Spindle Static moment of torsion, can continuously measure main axis one week respectively Moment of torsion during a position, suitable for the assembling and debugging of tricot machine.

Embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples：

Referring to attached drawing, the spanner for the rotation tricot machine main shaft designed, by overcoat 1, roller 2, inner sleeve 3, lever 4, baffle ring 5 Formed with clamp ring 6；Concrete structure is：Freewheel clutch is installed between the overcoat 1 and inner sleeve 3, the freewheel clutch It is that equally distributed 4 wedge grooves are machined with along around endoporus in overcoat 1, active configuration has a roller 2, each wedge in each wedge groove The angle of wedge of groove is consistent along the direction of 1 endoporus circumference of overcoat, and the angle of wedge is 3 ~ 6 °, is machined with screw hole in the side of overcoat, and with for The elongated lever 4 of operation couples, by pulling lever 4 during use, you can ensure along 7 rotation direction of main shaft pull when, roller 2 is not Skid, when reversely pulling, roller 2 slips easily over inner sleeve 3.

For the normal use for extending the service life of spanner, ensureing spanner, it is desirable to which overcoat 1, roller 2, inner sleeve 3 are indirectly Case hardness HRC >=60 of contacting surface；The quantity of the roller 2 is 4, and other number of parts are 1；It is 5 ° to design the angle of wedge, is being protected In the case of demonstrate,proving reliably working, the surface pressing of roller 2 is smaller；Designed to simplify, be not provided with spring spindle；Lever 4 and overcoat 1 It is threaded integral；Roller 2 and inner sleeve 3 are assembled by Fig. 1, the direction of overcoat 1 is related with the direction that main shaft 7 rotates, can To assemble in turn, can also be assembled with any one direction, and when inner sleeve 3 is inserted in main shaft 7, reselection direction, such as inner sleeve 3 Turn around to be inserted in main shaft 7.After roller 2 assembles, lubricating grease is smeared, baffle ring 5 is loaded onto, puts on clamp ring 6.

The main shaft 7, generally stretches out one section, for assembling driving parts, such as belt wheel on the head of tricot machine 8 or afterbody Deng.During using spanner（Such as Fig. 3）, inner sleeve 1 pass through clamp ring 6 hold tightly main shaft 7；Lever 4 back and forth is pulled, is rotated along main shaft 7 Direction（That is the clockwise direction of diagram 2）When pulling, roller 2 is rolled until pole on the face that overcoat 1, inner sleeve 3 are contacted at the same time Limit, roller 2 is compacted, while passes through the frictional force drives main shaft 7 with inner sleeve 3；7 rotation direction of inverse main shaft（That is the inverse time of diagram 2 Pin direction）When pulling, roller 2 is relaxed, and roller 2 is slipped over 3 contact position of inner sleeve, and space is provided to rotate main shaft 7 in next step； Some specific positions can be positioned by rotating main shaft 7；The moment of torsion of main shaft 7 can also be measured（As Fig. 3 shows）, overall merit master The precision that axis 7 assembles.During measurement, 4 end of lever hangs up spring scale 9, and spring scale 9 is back and forth pulled with hand, drives main shaft 7 to rotate, Pulling force is vertical with lever holding during reading, and main shaft 7 rotates a circle, can obtain a series of corresponding Spindle Static torque datas.
