Abstract
The invention relates to a flat key press mounting tyre device for a shaft. In order to solve the technical problems of extremely poor shaft runout and spots on the surface of the flat key caused by the prior art, the flat key press mounting tyre device for the shaft comprises an upper fixed plate and a lower fixed plate which are fixedly connected through guide pillars on the two sides thereof, a hydro-cylinder is fixed on the back face of the lower fixed plate, and a mandril of the hydro-cylinder is stretched out from the middle part of the lower fixed plate; a movable slide block is arranged on the guide pillars on the two sides of the upper fixed plate and the lower fixed plate in a sleeving way, is fixed with the mandril of the hydro-cylinder, and is moved between the upper fixed plate and the lower plate through the action of the hydro-cylinder; and two soft cushion blocks are respectively arranged on the back face of the upper fixed plate and the surfaces of the movable slide block and are arranged on the same perpendicular line. The rotating shaft is in contact with the cushion blocks in the device, and the cushion blocks have a function of protecting the appearances of the rotating shaft and the flat key so as not to damage the surfaces of the rotating shaft and the flat key.
Description
Technical field
The present invention relates to a kind of axle and press-fit device of tyre with flat key, this device is applicable to the production in enormous quantities industries such as work, particularly motor that flat key is installed on spindle nose.
Background technology
In the middle of our daily life; Being connected with of rotating shaft and other parts manyly realizes through flat key; Fixing between flat key and the rotating shaft then is to accomplish through the mode of beating, although we beat with copper hammer or after adding copper plate again, all inevitably can countershaft or flat key cause certain injury; Therefore the client might return goods, and will bring unnecessary economic loss to enterprise like this.
Summary of the invention
In order to overcome the beat technical problem of scar of overproof peaceful key surface of axle that prior art causes; The invention provides a kind of axle and press-fit device of tyre with flat key; This device has reasonable in design, and manufacturing and easy to use not only can be enhanced productivity; Reduce production costs, can also reduce worker's labour intensity.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: axle press-fits device of tyre with flat key; This device comprises upper mounted plate and bottom plate; Last bottom plate is fixedly connected by the guide pillar of its both sides, the fixed oil cylinder at the back side of bottom plate, and the oil cylinder push rod is stretched out by the middle part of bottom plate; Suit movable slider on the guide pillar of bottom plate both sides on described, movable slider and oil cylinder push rod are fixed, and the action through oil cylinder is slided movable slider between last bottom plate; At the back side of described upper mounted plate and the surface of movable slider the cushion piece is installed respectively, two cushion pieces are on the same vertical line.
For gaining in strength, described axle press-fits device of tyre with flat key, above that a side fixation side fixed head of fixed head and bottom plate.
Fixing suspension hook on described upper mounted plate.
The surface of the cushion piece at the said upper mounted plate back side is the plane.
The surface of the cushion piece on described movable slider surface is an arc.
Beneficial effect of the present invention is: axle uses flat key to press-fit contact with rotating shaft in the device of tyre be the cushion piece, owing to the cushion piece has the effect of protecting rotating shaft and flat key outward appearance, so it can not destroy by the peaceful key surface of countershaft; Because in the middle of the process that press-fits, rotating shaft is in a kind of free state, adopts the mode of pressurized that flat key is pressed in the keyway with the rotating shaft self poisoning, makes it keep reset condition, just can not produce broken destruction by countershaft, the promptly usually said rotating shaft problem of beating.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1, upper mounted plate, 2, bottom plate, 3, guide pillar, 4, oil cylinder, 5, the oil cylinder push rod, 6 movable sliders, 7, the cushion piece, 8, suspension hook, 9, the side fixed head, 10, rotating shaft, 11, flat key.
The specific embodiment
Below in conjunction with embodiment the present invention is further specified.
Shown in accompanying drawing, axle press-fits device of tyre with flat key, and this device comprises upper mounted plate 1 and bottom plate 2; Last bottom plate is fixedly connected by the guide pillar 3 of its both sides; Fixed oil cylinder 4 at the back side of bottom plate 2, and oil cylinder push rod 5 is stretched out by the middle part of bottom plate, suit movable slider 6 on the guide pillar of last bottom plate both sides; Movable slider 6 is fixing with oil cylinder push rod 5; Action through oil cylinder 4 is slided movable slider 6 between last bottom plate, at the back side of upper mounted plate 1 and the surface of movable slider 6 cushion piece 7, two cushion pieces be installed respectively be on the same vertical line.
Manufacturing process of the present invention is: at first adopt bottom plate 2 and oil cylinder 4 securing member to fix; And then adopt guide pillar 3 and fixed head 2 securing members to fix; Be installed in the movable slider that is pressed into lining 6 on guide pillar 3 and the oil cylinder push rod 5 subsequently and adopt securing member to fix; Press together last fixed block 1 and adopt securing member fixing with guide pillar 3 again, so just make up completion to the present invention together with suspension hook 8; In order to increase the intensity of mold, add upside fixed head 9 at upper mounted plate 1 and bottom plate 2.
As shown in the figure; During work; The location of rotating shaft 10 can realize that flat key 11 is pressed into through the cushion piece effect on the upper mounted plate among the rotating shaft through cushion piece 7, because the mounting means of employing quick change can satisfy the demand of the different diameters of axle between cushion piece 7 and upper mounted plate 1 and the movable slider 6.
