Description
Technical field
The utility model relates to screw locking device field, more particularly relates to a kind of with collet mechanism
Lock screw device.
Background technology
The retaining mechanism of existing automatic lock screw device is by electric screwdriver or pneumatic screwdriver, fixed cover, telescopic, dop etc.
Composition, when screw is blown to dop, when looking for screw hole in the case of not having any device to guide, holds very much
Easily the screw at dop is rejected so that operator is more difficult to find screw hole, operating efficiency to be substantially reduced,
The advantage of automatic locking screw machine can not be given full play to.
For the problem of above-mentioned existence, Publication No. CN 202763428U utility model patent is authorized to provide
A kind of novel automatic locking screw machine, including being fastened on the sliding sleeve that fixed cover is interior and can slide up and down along fixed cover,
The lower end of sliding sleeve is connected and is provided with the dop of through hole, also includes batch mouth being criticized control by electric screwdriver or gas, described batch of mouth
In the spring arranged through sliding sleeve inner chamber the through hole inserting dop, the side of described dop is provided with into nail pipe,
Described fixed cover sidewall has chute, is additionally provided with cylinder, and one end of described cylinder is through chute and by connecting
Ring set is connected on the outer wall of sliding sleeve, and the other end of described cylinder is connected by connecting rod and dop.Automatically screw is locked
A point nail cylinder for machine return back in situ, and the piston rod of cylinder pulls connecting rod to drive sliding sleeve compression press spring, makes to criticize
Mouth stretches out and withstands the screw at dop, now waits that operator lays a screw.This utility model is permissible
When making operator to screw, do not cause screw to retreat, thus improve the operating efficiency of operator, for lock automatically
The universal obstacle of having cleared away of filature, but although this solution solves the screw top at dop easily
The problem gone back, but in the case of automatically screwing, owing to screw external diameter is not of uniform size, screw terminal
Still screw hole it is difficult to find that.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of lock screw device, it is possible to prevent
Screw is pushed up back, finds screw hole accurately, and safe and reliable, workable.
The technical solution adopted in the utility model is as follows: a kind of lock screw device, including fixed cover, chuck, bullet
Spring and screwdriver, it is characterised in that: the lower end of described fixed cover is provided with base of the carrier head, and described chuck has two,
Two chucks are symmetrically mounted on base of the carrier head by pin, and the holding position of described chuck lower end is with back-off, institute
Stating screwdriver and be arranged on the inner side of base of the carrier head, the inner side of described chuck has a groove, the groove of two chucks
The composition that links together one screw blanking groove, screw blanking groove is corresponding with screwdriver position.
Further, the upper end of described chuck is provided with the spring-loaded draw-in groove of peace, and spring one end is arranged in draw-in groove,
The other end holds with base of the carrier head.
Further, the lower end of described fixed cover connects a screw feeding cylinder, screw feeding cylinder and screw blanking
Groove connects.
Compared with prior art, the utility model simple in construction, reasonable in design, by arranging at grips
One back-off, it is possible to effectively prevent screw from retracting, makes chuck find screw hole exactly, simple and efficient, improves
Reliability, safe and reliable, effectively reduce labour intensity and the error rate of operative employee.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of lock screw device described in the utility model;
Accompanying drawing 2 is the side view of lock screw device described in the utility model;
Accompanying drawing 3 is the structural representation of described back-off.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodiment
It is clearly and completely described, it is clear that described embodiment is only that the utility model part is implemented

As shown in Figure 1 and Figure 2, a kind of lock screw device, including fixed cover 1, chuck 2, spring 3 and screw
Criticizing 4, the lower end of described fixed cover 1 is provided with base of the carrier head 11, and described chuck 2 has two, two chucks 2
Being symmetrically mounted on base of the carrier head 11 by pin 21, chuck 2 can be opened along pin 21 for axle center, folder
The upper end of 2 is provided with the draw-in groove (not shown) installing spring 3, and spring 3 one end is arranged in draw-in groove, separately
One end holds with base of the carrier head 11, and spring 3 is used for making chuck 2 reset, and described screwdriver 4 is arranged on base of the carrier head
The inner side of 11, the inner side of described chuck 2 has a groove 23, when two chucks 2 close, two chucks
The groove 23 of 2 links together and constitutes a screw blanking groove 24, screw blanking groove 24 and screwdriver 4 position
Corresponding.
The lower end of described fixed cover 1 connects a screw feeding cylinder 5, screw feeding cylinder 5 and screw blanking groove 24
Connection.
As it is shown on figure 3, the holding position of described chuck 2 lower end can prevent screw quilt with back-off 22, back-off 22
Push up back.
During use, the screw in screw feeding cylinder 4 is by automatically dropping in screw blanking groove 24, and screw hangs
Hanging at the back-off 22 of chuck 2, then screwdriver 4 extends downwardly from being ejected by screw and screwing, chuck 2 edge
