Abstract
The utility model discloses a kind of dop paying machine for screw automatic locking, comprise chuck, the first jaw being symmetrically fixed on described chuck both sides by rotating shaft and the second jaw, isometric first connecting rod and second connecting rod, be provided with the chute extended along chuck axis direction outside the middle part of described chuck, in chute, be provided with a slide block; One end and first jaw of described first connecting rod are rotationally connected, and the other end and described slide block are rotationally connected, and one end of described second connecting rod and the correspondence position of the second jaw are rotationally connected, and the other end and described slide block are rotationally connected.The utility model is disclosed pays the dop of machine in lock screw process for screw automatic locking, effectively solve the undesirable condition because locating the crooked and malposition of screw that deficiency causes.
Description
[technical field]
The utility model relates to screw automatic locking and pays machine field, is specifically related to a kind of dop paying machine for screw automatic locking.
[background technology]
Current screw automatic locking is paid machine (or claiming automatic locking screw machine) and is widely used in all trades and professions, but there is the problem that screw lock is askew or screw lock is inclined always, one of them chief reason is exactly: in the process of lock screw, and dop could not ensure that screw is on center of collet line position always.As depicted in figs. 1 and 2, in prior art, the dop that machine paid by screw automatic locking comprises the first jaw 3 and the second jaw 4 being symmetrically fixed on chuck 1 both sides by rotating shaft, first jaw 3 is fixedly connected with outside chuck 1 respectively by spring 2 with the inner side on the second jaw 4 top, and screw 5 is held between the first jaw 3 and the second jaw 4; In prior art, screw automatic locking pays the dop of machine when discontinuity equalization, first jaw 3 and the second jaw 4 cannot ensure equal with the angle of center of collet line, thus make the center line of the screw be held on therebetween depart from center of collet line, cause that screw lock is askew or screw lock is inclined.
[summary of the invention]
For solving the problem, the utility model discloses a kind of dop paying machine for screw automatic locking, in lock screw process, effectively solving the undesirable condition because locating the crooked and malposition of screw that deficiency causes.
The technical solution of the utility model is as follows:
A kind of dop paying machine for screw automatic locking, comprise chuck, the first jaw being symmetrically fixed on described chuck both sides by rotating shaft and the second jaw, isometric first connecting rod and second connecting rod, be provided with the chute extended along chuck axis direction outside the middle part of described chuck, in chute, be provided with a slide block; One end and first jaw of described first connecting rod are rotationally connected, and the other end and described slide block are rotationally connected, and one end of described second connecting rod and the correspondence position of the second jaw are rotationally connected, and the other end and described slide block are rotationally connected.
The utility model is disclosed to be paid in the dop of machine for screw automatic locking, and the first jaw and the second jaw are symmetrically set in chuck both sides, is realized clamping by rotation around the shaft and is separated; One end of first jaw and first connecting rod is rotationally connected, one end of second jaw and second connecting rod is rotationally connected, slide block in the other end of first connecting rod and second connecting rod and chute is rotationally connected, chute extends along the axial direction of chuck, thus make the first jaw, the second jaw clamp and in separation process, keep the axisymmetrical with chuck, namely the first jaw and the second jaw remain identical movement range, thus ensure that the screw be held on therebetween aligns, effectively solve the undesirable condition because locating the crooked and malposition of screw that deficiency causes; Meanwhile, first, second connecting rod also contributes to alleviating the side force that first, second jaw is subject to, and extends the service life of first, second jaw.

Fig. 1 is the dop structural representation that in prior art, machine paid by screw automatic locking;
Fig. 2 is the working state figure of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment.
[detailed description of the invention]
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1 to Figure 3, the dop paying machine for screw automatic locking of the present utility model is comprised chuck 1, is symmetrically fixed on the first jaw 3 and the second jaw 4, isometric first connecting rod 7 and the second connecting rod 8 of described chuck 1 both sides by rotating shaft, be provided with the chute 9 extended along chuck 1 axis direction outside the middle part of described chuck 1, in chute 9, be provided with a slide block; One end and first jaw 3 of described first connecting rod 7 are rotationally connected, the other end and described slide block are rotationally connected, one end of described second connecting rod 8 and the correspondence position of the second jaw 4 are rotationally connected, the other end and described slide block are rotationally connected, namely second connecting rod 8 is identical with the link position of first connecting rod 7 and the first jaw 3 with the link position of the second jaw 4, about the axisymmetrical of chuck 1 after first connecting rod 7 has been connected with second connecting rod 8, thus before ensureing lock screw 5, the center line of screw 5 and chuck 1 centerline collineation; During lock screw 5, first, second jaw opens, and under the constraint of first connecting rod 7, second connecting rod 8, the amplitude that two jaws open is identical, thus the center line ensureing screw 5 still with the centerline collineation of chuck 1;
The utility model is disclosed to be paid in the dop of machine for screw automatic locking, and the first jaw 3 and the second jaw 4 are symmetrically set in chuck 1 both sides, is realized clamping by rotation around the shaft and is separated, first jaw 3 is rotationally connected with one end of first connecting rod 7, second jaw 4 is rotationally connected with one end of second connecting rod 8, slide block in the other end of first connecting rod 7 and second connecting rod 8 and chute 9 is rotationally connected, chute 9 extends along the axial direction of chuck, thus make the first jaw 3, second jaw 4 keeps with the axisymmetrical of chuck 1 in clamping and separation process, namely the first jaw and the second jaw remain identical movement range, thus ensure that the screw be held on therebetween aligns, effectively solve the undesirable condition because locating the crooked and malposition of screw that deficiency causes, meanwhile, first, second connecting rod also contributes to alleviating the side force that first, second jaw is subject to, and extends the service life of first, second jaw.
Preferably, the upper end of described first connecting rod 7 is connected by the upper end of pin with the first jaw 3, the same position of second connecting rod 8 upper end is connected by the upper end of pin with the second jaw 4, and the lower end of first, second connecting rod and the swing arm on described slide block top are rotationally connected, and is convenient to space and arranges;
Preferably, described first jaw 3 is fixedly connected with outside described chuck 1 respectively by spring 2 with the inner side on the second jaw 4 top, plays reset response by spring 2 to first, second jaw.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
