Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of flexible gearing for workpiece annealing, comprises flexible shaft 2, cannulated sleeve 4 and flexible bearing assembly 6.
For the flexible shaft 2 of the hollow shaft of non-metallic material is arranged in the inner cavity of cannulated sleeve 4, the two ends of described cannulated sleeve 4 are all threaded with described flexible bearing assembly 6, the described flexible shaft 2 of this flexible bearing assembly 6 supporting, at described flexible shaft 2, wear two ends difference connecting ejector pin 3 and the motor output shaft 1 that penetrates cannulated sleeve 4, described thimble 3 can be used to be threaded and also can use annular knurl to connect.
And the design of the hollow shaft of the non-metallic material of flexible shaft 2 is in order better to guarantee its degree of flexibility, when rotating, flexible shaft 2 forms non-rigid output.
In described cannulated sleeve 4 internal cavities, be provided with and intercept spring 5, at the outer wall of flexible shaft 2, be equipped with described obstruct spring 5, the inner diameter of described obstruct spring 5 is greater than the outer diameter of described flexible shaft 2, and described obstruct spring 5 does not contact with flexible shaft 2;
When flexible shaft 2 is during in the interior generation slight bending of cannulated sleeve 4, effect due to the obstruct spring 5 in cannulated sleeve 4, even if bend, flexible shaft 2 is also that line contacts with intercepting spring 5 inner sides, if and do not intercept spring 5, flexible shaft 2 is that face contacts with cannulated sleeve 4, so increase obstruct spring 5, can effectively reduce frictional force.
As shown in Fig. 2-7, described flexible bearing assembly 6 comprises outer back-up ring 61 and neck bush 62 and the steel ball 64 of supporting connection;
Described neck bush 62 is hollow cylinder, and on the inwall of this neck bush 62, evenly have 6 mounting holes 621, the outside scattering centered by the axle center of neck bush 62 of described mounting hole 621 is offered, and the central axis of described mounting hole 621 is perpendicular to the central axis of described neck bush 62, this mounting hole 621 is through hole, described mounting hole 621 is less than mounting hole 621 diameters of other parts and the diameter of described steel ball 64 with the diameter of the cavity connectivity part of neck bush 62, guaranteeing that steel ball is put into deenergize exposes 1/3 ball, and does not fall;
The internal cavities of neck bush 62 is communicated with and is formed by the first transmission channel 622 and the second transmission channel 623, the diameter of this first transmission channel 622 is less than the diameter of the second transmission channel 623, shown in the outer wall of the second transmission channel 623 be provided with the screw thread being connected with cannulated sleeve 4, and the diameter of described the first transmission channel 622 and the second transmission channel 623 is all less than the diameter of cannulated sleeve 4, the inner cavity diameter of described the first transmission channel 622 is less than the diameter of the workpiece 7 that needs processing, be when guaranteeing thimble 3 along with flexible shaft 2 retraction, neck bush 62 can intercept workpiece 7 outside,
Described outer back-up ring 61 is the hollow cylinder coordinating with neck bush 62, on the inwall of this outer back-up ring 61, have the mounting groove 611 being communicated with the mounting hole 621 of neck bush 62, this mounting groove 611 is circular groove, and circumference six position of halving of the mounting groove 611 on described outer back-up ring 61 inwalls mill out 6 fixed grooves 612, and the position of this fixed groove 612 is corresponding with described mounting hole 621;
In the mounting hole 621 being communicated with and mounting groove 611, be provided with flexible compression spring 63, one end of this flexible compression spring 63 is connected with steel ball 64, and described steel ball 64 is placed in mounting hole 621, and moves freely in this mounting hole 621; The minimum diameter of described outer back-up ring 61 outer walls is greater than the diameter of the boring cavity of cannulated sleeve 4.
When flexible bearing assembly 6 is installed, first steel ball 64 and flexible compression spring 63 are put into 6 mounting holes 621 of neck bush 62, then outer back-up ring 61 is coordinated to installation with the neck bush 62 that flexible compression spring 63 and steel ball 64 are housed by 6 place's fixed grooves 612, again outer back-up ring 61 rotations 30 are spent to 45 degree left and right, utilize cell wall and 63 restriction neck bush 62 and the axial relative movement of outer back-up ring 61 of flexible compression spring of mounting groove 611 and fixed groove 612, again flexible bearing assembly 6 integral body are screwed in cannulated sleeve 4, because the minimum outer diameter of outer back-up ring 61 is all greater than the outer wall maximum diameter of cannulated sleeve 4, so can utilize the outer back-up ring 61 of shaft shoulder restriction of cannulated sleeve 4 to move axially, then from the other end, pack the obstruct spring 5 matching with cannulated sleeve 4 inwalls into cannulated sleeve 4, one end of flexible bearing assembly 6 is never installed again and by same procedure, loads onto other flexible bearing assembly 6.
Described neck bush 62 is conical hollow cylinder with outer back-up ring 61.
When the whole output shaft 1 of driven by motor and flexible shaft 2 rotation, thimble 3 drives workpiece 7 rotations, due to the effect of flexible shaft 2 and flexible bearing assembly 6, when workpiece 7 rotates in its positioning element and the friction of this positioning element less, can not cause scratch to product design.
The working procedure of the present embodiment:
Before work, adjust the coaxality of heating coil, positioning element and motor three in this device and annealing device, motor output shaft 1 and flexible shaft 2 are linked together, then workpiece 7 is put into the positioning hole of positioning element.During work, together with thimble 3, push motor to positioning hole, when motor arrives restriction site, just in time thimble 3 penetrates workpiece 7, due to stopping of positioning element, workpiece 7 is pressed on thimble 3, and the effect due to flexible shaft 2, after compressing between workpiece 7 and positioning element axially substantially do not have stressed, motor output shaft 1 rotation subsequently, drive flexible shaft 2, thimble 3 and workpiece 7 rotate together, in rotary course, buffer function due to flexible shaft 2 and flexible bearing assembly 6, workpiece 7 is stressed less and degrees of freedom is larger in direction perpendicular to axial direction, only be subject to the position-limiting action of positioning hole, between workpiece 7 and positioning hole, frictional force is less, rotary course can not cause damage to workpiece 7 surfaces.Heating coil starts heating subsequently, has heated rear motor and has stopped the rotation, and motor is pushed back to initial position, unloads after workpiece 7, is loaded on another workpiece to be processed 7, enters next machining cycle.
In the time of flexible shaft 2 rotation, steel ball 64 in flexible bearing assembly 6 will play to the flexible shaft 2 rotating the effect of a buffering, steel ball 64 can move up and down along with the stressed variation of flexible shaft 2 in the passage of neck bush 62 and 61 formation of outer back-up ring, and because the design of mounting hole 621, steel ball 64 can all not reveal in the cavity of neck bush 62, but also can partly be connected on flexible shaft 2, thereby play the buffer function to flexible shaft 2.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
