Description

A kind of expanding machine gripper with gear pin

Technical field

The utility model relates to expanding machine auxiliary mould, is specifically related to the improvement of expanding machine gripper, belongs to expanding machine Computer Aided Design field.

Background technology

Expanding machine in the utility model is the equipment of the coil molding to motors such as high-voltage motor, double-fed wind power generator and specific type of electric machines, and coil is the important part of motor, and the use of quality on motor of coil has direct impact.But in coil rises by type process, find that there is coil covering damage and the incorrect situation of coil deformation, through on-the-spot trace analysis, find that the reason of damage is that the gripper original-pack in type process that rises has skew, for eliminating a kind of novel gripper of this hidden danger of quality design due to the position of firmly grasping cylinder when Long-Time Service causes wearing and tearing and loosens and cause rising by type.

Find that following patent and the utility model have similarity by domestic retrieval:

Application number is 201220695009.5, name is called that the utility model of " a kind of expanding machine and end winding Anti-inclining thereof " discloses a kind of end winding device preventing tilting, comprise the frock with smooth surface, this frock is rotatably connected on tooling connecting, and the smooth surface of this frock can fit with coil.During work, the position of adjustment tooling connecting, frock is rotated around tooling connecting simultaneously, the smooth surface of frock and coil are fitted, in the process of the Leading Edge Deformation of coil, the smooth surface of frock is synchronoused working with the distortion of coil, remains to fit with coil.Thus making in the process of being out of shape at the wire turn of coil, its surface is subject to the pressure from frock all the time and keeps, with the laminating of smooth surface, not tilting of wire turn not being misplaced.Effectively ensure that the evenness of end winding wire turn.This utility model also discloses a kind of expanding machine with above-mentioned end winding device preventing tilting.

Although the utility model that application number is 201220695009.5 also can prevent motor coil deformation incorrect, but this utility model is the shape by changing working base, make in the process of the Leading Edge Deformation of coil, the smooth surface of frock remains fits with coil, thus reaches the effect do not misplaced that do not tilt of wire turn.In sum, application number be 201220695009.5 utility model can not solve in the utility model due to expanding machine gripper wearing and tearing and loosen cause coil covering damage and the incorrect problem of coil deformation, so this problem still needs to be studied further.

Utility model content

The technical problems to be solved in the utility model is:

1. prevent the skew of promptly cylinder position;

2. prevent insulating motor coil layer damage and coil deformation incorrect.

Pin is with the problems referred to above, and the technical scheme that the utility model proposes is: a kind of expanding machine gripper with gear pin, has bolt hole in base, to be fixed on by gripper promptly on cylinder, base is fixed with two gear pins by bolt.

Further, the longitudinal section of base is right-angled trapezium, but the hypotenuse of right-angled trapezium is not straight line but arc-shaped edges, and two gear pins are fixed on the upper bottom surface place of base.

Further, the centre position of base has the bolt hole of a through upper bottom surface and bottom surface, promptly also has corresponding bolt hole in cylinder, and gripper is fixed on by bolt passing through bolt hole to be firmly grasped on cylinder.

Further, be fixed with columned gear pin in the bolt hole both sides of base, base and gear pin are an entirety, and the diameter of two cylindric gear pins is identical with height.

Further, have two pin-and-holes corresponding with two gear pins in promptly cylinder, when gripper is bolted on promptly on cylinder, gear pin is also arranged in the pin-and-hole of correspondence.

The utility model has the advantages that: by loading onto two fixing gear pins on gripper, gear pin is made to limit promptly cylinder together with bolt, effectively prevent the skew that promptly cylinder produces in coil rises by type process, thus effectively prevent insulating motor coil layer damage and coil deformation incorrect, reduce equipment failure rate simultaneously, save maintenance of equipment expense, improve the rate of comprehensive utilization of equipment.

In figure: 1 gripper, 11 gear pins, 12 bases, 121 bolts hole, 122 upper bottom surfaces, 123 bottom surfaces, 2 firmly grasp that cylinder, 21 promptly refers to, 22 pin-and-holes, 3 bolts.

Specific embodiment

Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the utility model:

Embodiment one

As depicted in figs. 1 and 2, the longitudinal section of base 12 is right-angled trapezium, but the hypotenuse of right-angled trapezium is not straight line but arc-shaped edges, two diameters are upper bottom surface 122 place that the columned gear pin 11 of 6 millimeters is fixed on base 12, and gear pin 11 and base 12 are an entirety.Bolt hole 121, two gear pins 11 that the centre position of base 12 has a through upper bottom surface 122 and a bottom surface 123 are positioned at the both sides of bolt hole 121.As shown in Figure 3 and Figure 4, promptly also have corresponding bolt hole 121 in cylinder 2, gripper 1 is fixed on through bolt hole 121 and firmly grasps on cylinder 2 by bolt 3.Now, the upper bottom surface of base 12 122 and promptly cylinder 2 are close to, and gear pin 11 is also arranged in the pin-and-hole 22 of promptly cylinder 2 correspondence.

Carry out between the promptly finger 21 coil being placed on the promptly cylinder 2 of expanding machine coil rise type action time, because original gripper does not have gear latch structure, there is skew the position of firmly grasping cylinder 2 when gripper weares and teares because Long-Time Service causes and loosens and cause rising by type, thus causes promptly finger 21 damaged by coil covering and make coil deformation incorrect.Therefore, usually rise after type action in first time and go promptly cylinder 2 to strike back original position with shaping hammer, just can carry out second time and to rise type action.But do like this, except damaging coil in beaing, also very consuming time, has a strong impact on operating efficiency.

For the problems referred to above, as Fig. 3, shown in Fig. 4 and Fig. 5, after two gear pins 11 are fixed at upper bottom surface 122 place of gripper 1, carry out between the promptly finger 21 that coil is placed on the promptly cylinder 2 of expanding machine coil rise type action time, promptly cylinder 2 is limited by the columned gear pin 11 of four in two grippers 1 of both sides and two bolts 3, the position of promptly cylinder 2 in coil rises by type process is made to produce skew, promptly correct the carrying out of promptly finger 21 energy of cylinder 2 is risen type, thus ensured the type quality that rises of coil, also significantly improve operating efficiency, in production practices, find that the utility model can increase work efficiency more than 40%.

Obviously, under the prerequisite not departing from principle described in the utility model, the some improvement made or modification all should be considered as protection range of the present utility model.
