Abstract
The invention discloses a shaft clamping device. The device comprises a stand; the stand is internally provided with a left pressing part and a right pressing part which both have a certain degree of freedom for horizontal movement; the left pressing part and the right pressing part are coaxial; the left pressing part and the right pressing part are internally and coaxially provided with internal threads with opposite screwing directions; the left pressing part and the right pressing part are in threaded connection with a force application rod; the end part of the force application rod props against the stand; the lower part of the left pressing part is provided with an upwards-inclined slope; the lower part of the right pressing part is provided with a downward-inclined slope; the two slopes are consistent in height and are arranged oppositely; a pressing plate is arranged between the two slopes; and a through hole which is vertical to the pressing plate, is arranged horizontally and can allow a workpiece to penetrate through is arranged below the pressing plate and in the stand. The shaft clamping device is simple in structure, convenient to operate and stable in clamping the workpiece.
Description
Technical field
The present invention relates to machine tools, be specifically related to a kind of shaft clamping device for clamping shaft-like workpiece.
Background technology
Clamping device is widely used for manufacturing, as to punching press, riveted joint, the welding of workpiece, paste or solidify etc. and usually need the position relationship that keeps correct in the process, clamping device has various reference surfaces or point, workpiece can accurately be located, so clamping device is considered to requisite parts in the processing industry.
Shaft clamping device normally two of clamp axis is brought in axle is carried out clamping and positioning, and the drawback of clamping is like this, if axle is long, the two ends of blocking so axle are not only unstable, and the clamping overlong time also can make axle deform, and affects crudy.And by axle is penetrated in the hole, the circumferential cross-section of clamp axis, not only clamping is stable, concerning the long axle of length, also can not affect its crudy, and existing this shaft clamping device complex structure often is not easy to operation.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, convenient operation, the stable clamping device of clamping shaft-like workpiece.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of shaft clamping device, comprise support, left compressing member and right compressing member with the free degree of moving horizontally is set in the support, left compressing member and right compressing member are coaxial, the coaxial opposite internal thread of rotation direction that is provided with in left compressing member and the right compressing member, left compressing member and right compressing member are threaded with a force application rod, the force application rod end props up support, left compressing member bottom has acclivitous inclined-plane, right compressing member bottom has downward-sloping inclined-plane, two bevel altitudes unanimously are oppositely arranged, and are provided with pressing plate between two inclined-planes, are positioned at the pressing plate below in the support and are provided with vertical with pressing plate and the horizontally disposed through hole that wears workpiece.
This device holding workpiece principle is as follows: have the opposite internal thread of rotation direction in left compressing member and the right compressing member, has levogyrate inner thread with left compressing member, it is example that right compressing member has the dextrorotation internal thread, be rotated counterclockwise force application rod, because compressing member and pressing plate that force application rod is threaded offset, therefore force application rod will be not can precession, the relative force application rod of left compressing member outwards moves, the relative force application rod of right compressing member inwardly moves, distance between two compressing members reduces, two inclined-planes of two compressing member bottoms will apply downward power to pressing plate, effect lower platen in this power moves down clamping work pieces.When discharging workpiece, the force application rod that turns clockwise gets final product.This device clamping shaft-like workpiece is stable, simple in structure, easy to operate.
Further, pressing plate and left compressing member and right compressing member are connected with back-moving spring.The back-moving spring of this device has pulling force upwards to pressing plate, behind the release workpiece, has the effect that pressing plate is resetted.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Shaft clamping device as shown in Figure 1, comprise support 1, be provided with left compressing member 2 and right compressing member 3 that horizontal slip connects in the support 1, left compressing member 2 and right compressing member coaxial 3, be provided with levogyrate inner thread in the left compressing member 2, be provided with the dextrorotation internal thread in the right compressing member 3, left compressing member 2 and right compressing member 3 are threaded with a force application rod 7, left compressing member 2 bottoms have acclivitous inclined-plane 4, right compressing member 3 bottoms have downward-sloping inclined-plane 5, two bevel altitudes unanimously are oppositely arranged, be provided with pressing plate 6 between two inclined-planes, be connected with wire spring 8 between pressing plate 6 and left compressing member 2 and the right compressing member 3, be positioned at pressing plate 6 belows in the support 1 and be provided with and the pressing plate 6 vertical and horizontally disposed through holes that wear workpiece 9, during holding workpiece, the workpiece 9 that pressing plate 8 compresses in the through hole.
This device holding workpiece principle is as follows: be rotated counterclockwise force application rod, the relative force application rod of left compressing member outwards moves, and the relative force application rod of right compressing member inwardly moves, distance between two compressing members reduces, two inclined-planes of two compressing member bottoms will apply downward power to pressing plate, and pressing plate moves down, clamping work pieces.When discharging workpiece, the force application rod that turns clockwise, left compressing member inwardly moves, and right clamping element outwards moves, and two compressing members are apart from increase, and the active force of pressing plate is reduced gradually on two inclined-planes and away from pressing plate, pressing plate moves under the effect of spring, discharge workpiece.
Claims (2)
1. shaft clamping device, it is characterized in that, comprise support, left compressing member and right compressing member with the free degree of moving horizontally is set in the support, left compressing member and right compressing member are coaxial, the coaxial opposite internal thread of rotation direction that is provided with in left compressing member and the right compressing member, left compressing member and right compressing member are threaded with a force application rod, left compressing member bottom has acclivitous inclined-plane, right compressing member bottom has downward-sloping inclined-plane, two bevel altitudes unanimously are oppositely arranged, and are provided with pressing plate between two inclined-planes, are positioned at the pressing plate below in the support and are provided with vertical with pressing plate and the horizontally disposed through hole that wears workpiece.
2. shaft clamping device according to claim 1 is characterized in that, pressing plate and left compressing member and right compressing member are connected with back-moving spring.
