Abstract
The utility model relates to an elastic jacking device which comprises a telescopic shell, a fixed shell, and a spring. The fixed shell is fixedly arranged in the telescopic shell. One end of the fixed shell extends out of the telescopic shell. A single-row radial ball bearing is arranged at the end, extending out of the telescopic shell, of the fixed shell. A telescopic shell cover is fixedly arranged at one end of the telescopic shell. A through hole communicated with an inner cavity of the telescopic shell is formed in the telescopic shell cover. A workpiece ejector rod is arranged in the through hole. One end of the workpiece ejector rod is connected with a single direction thrust ball bearing . The workpiece ejector rod penetrates through the single direction thrust ball bearing and is connected with a spring sleeve. One end of the spring is connected to the spring sleeve, and the other end of the spring is fixed in an inner cavity of the fixed shell. According to the elastic jacking device, the spring is matched with the workpiece ejector rod and the spring sleeve, and the single-row radial ball bearing is matched with the single direction thrust ball bearing, so that the workpiece ejector rod in the elastic jacking device is made to maintain not rotating, and the workpiece ejector rod can not rotate along with the rotation of a chamfering machine tool rest. Consequently, the surface of a workpiece can not be damaged.
Description
Technical field
The utility model relates to a kind of elasticity holding device, relates to specifically a kind of elasticity holding device be fixed on the beveler knife rest.
Background technology
For holding device on the beveler knife rest, at knife rest, added man-hour for general, holding device can rotate along with the rotation of knife rest, easily causes damage for the surface of the work held out against like this, affects the yields of workpiece, causes unnecessary loss.
The utility model content
The utility model purpose is the elasticity holding device that a kind of anti-rotation is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of elasticity holding device, comprise telescopic shell, fixed housing, spring, and described fixed housing is fixedly installed on telescopic shell inside, and an end stretches out telescopic shell; Described fixed housing stretches out the telescopic shell end and is provided with single-row radial ball bearing; Described telescopic shell one end is installed with the telescopic shell lid; Described telescopic shell covers and is provided with the through hole communicated with the telescopic shell inner chamber; The workpiece push rod is installed in described through hole; Described workpiece push rod one end is connected with single direction thrust ball bearing; Described workpiece push rod is connected with spring housing through single direction thrust ball bearing; Described spring one end is connected on spring housing, and the other end is arranged in the fixed housing inner chamber.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of elasticity holding device of the utility model scheme, by coordinating of spring and workpiece push rod and spring housing, take a step forward workpiece pre-tightening is put in place in the workpiece machining, radial load while by the single-row radial ball bearing arranged, bearing blade holder turns on fixed housing, the single direction thrust ball bearing arranged on the workpiece push rod bears axial load, in working angles, due to single-row radial ball bearing and single direction thrust ball bearing acting in conjunction, make the workpiece push rod in the elastic top materials device keep not rotating, can not rotate with the beveler knife rest, therefore can not damage surface of the work.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is a kind of elasticity holding device of the present utility model;
Wherein: 1, telescopic shell; 2, fixed housing; 3, spring; 4, screw; 5, single-row radial ball bearing; 6, telescopic shell lid; 7, workpiece push rod; 8, single direction thrust ball bearing; 9, spring housing; 10, through hole.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of elasticity holding device described in the utility model, comprises telescopic shell 1, fixed housing 2, spring 3, and described fixed housing 2 is fixedly installed on telescopic shell 1 inside, and an end stretches out telescopic shell 1; Described fixed housing 2 stretches out the telescopic shell end and is provided with single-row radial ball bearing 5; Described telescopic shell 1 one ends are installed with telescopic shell lid 6; Described telescopic shell lid 6 is provided with the through hole 10 communicated with telescopic shell 1 inner chamber; In described through hole 10, workpiece push rod 7 is installed; Described workpiece push rod 7 one ends are connected with single direction thrust ball bearing 8; Described workpiece push rod 7 is connected with spring housing 9 through single direction thrust ball bearing 8; Described spring 3 one ends are connected on spring housing 9, and the other end is arranged in fixed housing 2 inner chambers.
Add man-hour, this elasticity holding device is arranged on the beveler knife rest, by coordinating of spring 3 and workpiece push rod 7 and spring housing 9, take a step forward workpiece pre-tightening is put in place in the workpiece machining, when workpiece withstands on workpiece push rod 7, workpiece push rod 7 is stressed to be shunk left, be connected to the also stressed contraction of spring 3 on spring housing 9, play like this effect that reduces stressed buffering, when workpiece is held out against spring 3 compression limit, workpiece just is fixed, radial load while by the single-row radial ball bearing 5 arranged, bearing blade holder turns on fixed housing 2, the single direction thrust ball bearing 8 arranged on workpiece push rod 7 bears axial load, in working angles, due to single-row radial ball bearing 5 and single direction thrust ball bearing 8 both actings in conjunction, make the workpiece push rod 7 in the elastic top materials device keep not rotating, can not rotate with the beveler knife rest, therefore can not damage surface of the work.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
