Abstract

The utility model relates to a supporting equipment which can move freely. A center restoration rod is fixedly connected with a restoration plate through an upper slide plate, a restoration plate, a lower slide plate and the center hole of a pedestal. Two ends of the center restoration rod are respectively provided with an upper cap, a lower cap and a spring plate. The upper shell is provided with a center hole, whose inside is respectively provided with a column spiral spring, and the other end of the column spiral spring is respectively pressed on the cone surfaces of the upper cap and the lower cap. A moveable cavity is formed between the spring seat, the upper shell and the lower slide plate fixedly positioned on the pedestal, and the upper shell is pressed on the upper slide plate. A holder between the upper and the lower slide plate is provided with a plurality of supporting steel balls, and the restoration plate is sleeved in the holder, and a volute spring is sleeved on the outside of the holder. The inner wall of the shell is provided with a plurality of arc shaped plate spring fixed by the rivet, and the other end of each plate spring is supported on the outside side wall of the upper shell. The utility model has the advantages of that: the utility model is of a simple structure and convenient installing and maintenance, whose working friction resistance is small, and the utility model is particularly applicable for the working occasion whose moving range is smaller and the moving direction is optional. The utility model chooses the stiffness of different spring in a complex manner, which can make the equipment stably work in proper elastic resistance state. The rolling effect of the steel ball makes the friction resistance extremely small.

Description

The support device that can move freely

Affiliated field: the utility model relates to a kind of support device that can move freely.

Background technique: in the design process of engineering goods, often need to realize some comparatively special supports, promptly require supported parts in certain planar range, freely to move by any direction.In the existing machinery technology, generally all adopt guide rail or roller to realize unidirectional move, to the movement requirement of different direction the guide rail of different direction or the composite set of roller need be set then; General joint arrangement is swung around fixing sphere location because of it, thus can't realize moving freely of plane, and the frictional force of above-mentioned mechanical device is bigger, thereby limited the scope of its use.

Summary of the invention: the purpose of this utility model provides a kind of simple in structure, convenient for installation and maintenance, support device that can move freely that surface friction drag is minimum.The purpose of this utility model realizes by following structure: the utility model is a kind of support device that can move freely, the center release link is passed upper slide, restoring board, the center hole of lower skateboard and base is also fixedlyed connected with restoring board, release link two ends, center have cap respectively, following cap, spring seat, upper casing has center hole, cylindrically coiled spring is installed respectively in the center hole, the cylindrically coiled spring the other end is fitted in cap respectively, on the conical surface of following cap, spring seat, upper casing and be fixed on and form a removable cavity between the lower skateboard on the base, upper casing is fitted on the upper slide, on, a plurality of supporting steel balls are installed in the retainer between the lower skateboard, suit restoring board in the retainer, the outer suit of retainer volute spring, install and fix the flat spring of the fixing circular arc of a plurality of rivets on the shell madial wall, each flat spring the other end is bearing on the upper casing outer side wall.The utility model is formed moving member by upper casing and upper slide, and shell, base and lower skateboard are formed fixed component; Up and down between two plane slide plates, insert separately and keep some steel balls of its mutual alignment by retainer.By the free-rolling action of steel ball, make moving member in certain planar range, freely to move by any direction.Simultaneously, comprise at each parts Returnning spring all is housed between moving member, fixed component and the rolling member, keep the mutual alignment of each parts with this.The utility model has the advantages that: simple in structure, convenient for installation and maintenance, surface friction drag is minimum during its work, is particularly useful for less and the workplace that movement direction is random of moving range.The utility model is synthetically chosen the rigidity of various springs, and this device is stably worked under suitable elastic resistance condition.And because the rolling action of steel ball makes surface friction drag minimum.

Embodiment:

The utility model as shown in Figure 1 is a kind of support device that can move freely, center release link 15 is passed upper slide 2, restoring board 8, the center hole of lower skateboard 5 and base 4 is also fixedlyed connected with restoring board 8, release link 15 two ends in center have cap 14 respectively, following cap 16, spring seat 12, upper casing 1 has center hole, cylindrically coiled spring 9 is installed respectively in the center hole, cylindrically coiled spring 9 the other ends are fitted in cap 14 respectively, on the conical surface of following cap 16, spring seat 12, upper casing 1 and be fixed on and form a removable cavity between the lower skateboard on the base 4, upper casing 1 is fitted on the upper slide 2, on, a plurality of supporting steel balls 6 are installed in the retainer 7 between the lower skateboard, retainer 7, interior suit restoring board 8, retainer 7 outer suits volute spring 11, install and fix the flat spring 10 of the fixing circular arc of a plurality of rivets 13 on shell 3 madial walls, each flat spring 10 the other end is bearing on upper casing 1 outer side wall.Between described upward cap 14 and the upper slide 2 is Spielpassung, is Spielpassung between following cap 16 and the base 4.By Fig. 1 one Fig. 2 as can be known, the utility model is that pack into upper casing 1 of upper slide 2 is formed moving member, with lower skateboard 5 insert base 4 and shell 3, spring abutment 12 is formed fixed components, and be equipped with between two plane slide plates up and down by steel ball 6, retainer 7 center release links 15, on cap 14, the rolling member formed of cap 16 and restoring board 8 down.At above-mentioned three parts Returnning spring 9, spring 10 and spring 11 are housed each other, thereby can recover and keep the mutual alignment of each parts.Above-mentioned spring all can adopt flat spring, wire spring, plane scroll spring and various helical spring to realize its reset response.

Described restoring board can also can be located by its cylindrical and realize its reset response by the endoporus location of retainer 7.

Moving member of the present utility model, fixed component and rolling member all have Returnning spring each other, to keep the mutual alignment of each parts.As shown in Figure 1, two cylindrical screws 9 are separately fixed in the center hole of upper casing 1 and spring seat 12, and the other end combines with the conical surface of last cap 14 and following cap 16, between last cap 14 and the upper slide 2; Be Spielpassung between following cap 16 and the base 4,, can limit three mutual alignments between parts by helical spring 9 so upward cap 14, following cap 16 can move freely along with restoring board 8.

Spring 11 is plane scroll springs, and its inner ring engages with retainer 7 and the outer ring engages with the inner periphery of upper casing 1.Some the flat springs 10 with the fixing circular arc of rivet 13 are arranged on the inner periphery of shell 3, and its end is pressed on the outer cylinder surface of upper casing 1, reaches the purpose that limits its mutual alignment with this.

When external force acted on upper casing 1, by the rolling action of steel ball, the elastic force that moving member overcomes each spring moved, and to the moving range equalization of any direction; After the external force effect disappeared, moving member was got back to initial position under the elastic force effect of each spring.Rolling member also according to this principle carry out work, but its stroke is 1/2 of a moving member stroke.In an embodiment, except that standard piece such as various springs and rivet, remaining parts is circular pieces among Fig. 1.
