The inner holes of the die pressing sleeve, the lead-in die sleeve and the demoulding seat are in clearance fit with the mandrel seat, and the depth of the inner rabbets of the die pressing sleeve and the lead-in die sleeve is greater than the height of the outward protruding winding at the end part of the stator. The outer diameter of the side of the die sleeve disc is equal to the outer diameter of the stator and is in clearance fit with the machine base. The excircle of the guide-in die sleeve is provided with deviations in two sections, the upper half section is in clearance fit with the machine base, the lower half section is in transition fit with the machine base, and the chamfer of the downward end face is an arc angle. The upward end part of the demoulding seat is provided with a spigot in clearance fit with the stator, and the depth from the bottom edge of the spigot to the inner hole is equal to the height of the guide-in die sleeve. In the press mounting process, the whole plane of the press die sleeve acts on the upper end face of the stator, and the stator and the machine base are uniformly stressed and do not deform axially. The utility model discloses the installation is easy, and the pressure equipment is put in place the natural drawing of patterns, and the pressure equipment work efficiency is high, is particularly suitable for doing the pressure equipment in batches.
Description
Technical field
The utility model relates to a kind of press mounting tool, and specifically, the utility model relates to the built-in stator press-loading instrument of a kind of thin-walled support.
Background technology
Motor stator is an interference fits with cooperating of support, and stator is inserted in the support by press-fit approach.The common electric machine support is a cast member, and wall thickness is thicker relatively, its structural strength height, and good rigidly, support do not produce distortion in the stator press-loading process and after press-fiting, and satisfy the instructions for use of motor.But pharmacy and food machinery have hygienic requirements in addition to the prestowage motor, and the electric machine stand outer wall must smoothly could be realized purpose easy to clean.This type of electric machine stand plate press forming, relatively poor because of its thin-wall part rigidity, directly press-fit with prior art and easily to cause frame deformation, and work efficiency is low, quality be cannot say for sure can not satisfy batch production requirement by card.
The utility model content
The utility model is primarily aimed at prior art yielding shortcoming of thin-walled support when press-fiting stator, proposes a kind of built-in stator press-loading instrument of thin-walled support with guiding structure.This tool construction simply, evenly stressed, quick importing, press-fit the efficient height.
The utility model is achieved through the following technical solutions technical goal.
The built-in stator press-loading instrument of thin-walled support, it comprises pressing mould sleeve, imports die sleeve, demoulding seat and mandrel seat.Described pressing mould sleeve, importing die sleeve, demoulding seat are discoid component, endoporus and mandrel seat matched in clearance, and the pressing mould sleeve and the importing die sleeve inner stopper degree of depth are greater than stator end evagination winding height.Improvements are: described pressing mould sleeve web external diameter equal stator outer diameter and with the support matched in clearance.Described importing die sleeve cylindrical divides two sections deviation is set, upper semisection and support matched in clearance, and lower semisection and support interference fits are arc chord angle towards the lower surface chamfering.Described demoulding seat is provided with the seam that cooperates with stator gap towards the upper end, seam base to interior hole depth equals to import the height of die sleeve.
Importing die sleeve in the said structure is the arc chord angle of R3～6mm towards the lower surface chamfering, and arc chord angle helps importing cooperating of mould and support.
The utility model compared with prior art has following good effect:
1, the circular arc guiding structure is simple, and is easy to manufacture;
2, stator is by importing the die sleeve supporting and importing the support inner chamber, and the whole plane effect of pressing mould sleeve is in the stator upper surface, and stator shaft orientation is stressed evenly, and to press-fit the back indeformable press-fiting the process neutralization for support;
3, the mandrel seat cooperates with stator inner hole, and accurate positioning press-fits disposable putting in place, press-fits quick.
Description of drawings
Accompanying drawing is the utility model structural profile schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The built-in stator press-loading instrument of thin-walled support shown in the drawings, it is a main component with mandrel seat 6, other is furnished with pressing mould sleeve 1, importing die sleeve 3 and the demoulding seat 5 of plate-like.Described demoulding seat 5 and mandrel seat 6 matched in clearance are provided with the seam with stator 2 matched in clearance towards the upper end, seam base to interior hole depth equals to import the height of die sleeve 3.The described importing die sleeve 3 and the pressing mould sleeve 1 inner stopper degree of depth are greater than stator 2 end evagination winding height, endoporus and mandrel seat 6 matched in clearance.Pressing mould sleeve 1 web external diameter equal stator 2 external diameters and with support 4 matched in clearance, import die sleeve 3 cylindricals and divide two sections deviation is set, upper semisection and support 4 matched in clearance, lower semisection and support 4 interference fits, towards the lower surface chamfering is arc chord angle, and arc chord angle is R4mm in the present embodiment.When enforcement stator 2 press-fits operation with support 4, at first demoulding seat 5 covers are installed on the mandrel seat 6, location and installation support 4 in demoulding seat 5 upper end seams, import die sleeve 3 and cooperate with support 4 upper end endoporus with the end that arc chord angle is arranged, axial again suit stator 2 imports die sleeve 3 supporting stators 2, last suit pressing mould sleeve 1, by exerting pressure to pressing mould sleeve 1, stator 2 enters in support 4 inner chambers along importing die sleeve 3, and it is that stator 2 is in place that importing die sleeve 3 finally falls in the demoulding seat 4.Press-fit that pressing mould sleeve 1 whole plane effect is in stator 2 upper surfaces in the process, stator 2 axially loadeds are even, and to press-fit the back indeformable press-fiting the process neutralization for support 4.The utility model is installed easily, and the nature demoulding that is press-fit into place press-fits the work efficiency height, satisfies batch production requirement.
