Abstract
The utility model discloses a screw thimble device for multi -wire saw includes: the screw movable striking piece is put to the screw section of screw cover, on the axle sleeve along the axis direction be provided with with this screw assorted screw hole, mounting screw is on this screw hole, just screw section leaves the confession outside the screw hole the length surplus of striking head activity, the application of force is in the striking head, thereby makes head of its striking screw drive axle sleeve and roller pivot separation. The utility model discloses to almost not damage of screw, improved production efficiency, reduced manufacturing cost.
Description
Technical field
The utility model belongs to multi-wire saw processing unit (plant) technical field, the screw push pin device of the particularly roller handling of semiconductor crystal multi-line cutting machine.
Background technology
The axle sleeve of multi-line cutting machine and the contact end face of roller rotating shaft are precision-fit device, to ensure the running of roller long-time stable, have extremely important impact to cutting processing.When dismantling roller, usually using common screw thimble to unload Lower shaft sleeve, as shown in Figure 1, by being threaded through 8 screw thimbles 3 of axle sleeve 2, axle sleeve 2 being pushed up the contact end face 4 from roller rotating shaft 1, and then axle sleeve 2 is unloaded.During owing to screwing screw thimble 3, the continuous extrusion screw thimble 3 of meeting, easily causes screw thimble 3 face deformation, causes it to fracture in screwed hole, cause serious damage to axle sleeve 2, cause wearing and tearing simultaneously, affect quality of fit to the contact end face 4 of roller rotating shaft 1.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of screw push pin device for multi-line cutting machine.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of screw push pin device for multi-line cutting machine comprises: screw, movable impact block is equipped with in the threaded shank of described screw, axle sleeve is provided with in the axial direction the screwed hole matched with this screw, described screw is arranged on this screwed hole, and described threaded shank leaves the length surplus for described impact head activity outside screwed hole; Force in impact head, make its head clashing into screw thus drive axle sleeve to be separated with roller rotating shaft.
Further, described threaded shank is provided with the radial flange protruded, and enters the length of described screwed hole for limiting threaded shank.
Further, two described screw push pin device are arranged on described axle sleeve symmetrically.
The advantage of a kind of screw push pin device for multi-line cutting machine of the utility model is: in use, compare with existing screw thimble, to screw not damaged, convenient to operation, without potential safety hazard; Meet the roller handling requirement of various multi-line cutting machine; Being applied on screw, that axle sleeve is separated with interior contact surface power is outside power, avoids that screw is inwardly stressed to be withstood on interior contact surface and produce distortion; Get axle sleeve with conventional screw to compare, drop to 2 screw push pin device by 8 screw thimble quantity, and screw is not almost damaged, improve production efficiency, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the use schematic diagram of screw thimble in prior art;
Fig. 2 is the view profile of A-A in Fig. 1;
Fig. 3 is the structural representation of the utility model for the screw push pin device of multi-line cutting machine.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe detailed description of the invention of the present utility model in detail.
Be illustrated in figure 3 the specific embodiment of a kind of screw push pin device for multi-line cutting machine of the utility model, in the present embodiment two screw push pin device are arranged on axle sleeve 2 symmetrically, specifically comprise: screw 5, movable impact block 6 is equipped with in the threaded shank 52 of screw 5, axle sleeve 2 is provided with screwed hole 8 in the axial direction, screwed hole 8 and screw 5 match, screw 5 is arranged on screwed hole 8, threaded shank 52 leaves length surplus outside screwed hole 8, it is movable in the axial direction that this length surplus is used for for impact head 6, threaded shank 52 is provided with the radial flange 7 protruded, the length that threaded shank 52 enters screwed hole 8 is limited by flange 7.
During dismounting, outwards force in impact head 6 along axis, the head 51 making it clash into screw 2 thus drive axle sleeve 2 be separated with roller rotating shaft 1.
Advantage is: in use, compares with existing screw thimble, to screw 5 not damaged, convenient to operation, without potential safety hazard; Meet the roller handling requirement of various multi-line cutting machine; Being applied on screw 5, that axle sleeve 2 is separated with interior contact surface power is outside power, avoids that screw 5 is inwardly stressed to be withstood on interior contact surface and produce distortion; Get axle sleeve with conventional screw thimble to compare, drop to 2 screw push pin device by 8 screw thimbles, and screw 5 is not almost damaged, improve production efficiency, reduce production cost.
Above-mentioned example is just for illustration of the utility model, and embodiment of the present utility model is not limited to these examples, and what those skilled in the art made meets the various detailed description of the invention of the utility model thought all within protection domain of the present utility model.
