Abstract
The invention relates to the field of the manufacturing of a motor and discloses a compound mould guide structure for the motor. The structure comprises a guide post, a retainer, a guide sleeve, a ball, a spring, a pull rod, a baffle block, a gland and a cushion cover, wherein the retainer is in non-clearance fit with the guide post and the guide sleeve respectively; the guide post is in conic-surface fit with the cushion cover; the spring is arranged outside the guide post and between the cushion cover and the retainer; the guide sleeve is fixed with an upper template; and the cushion cover is fixed with a lower template. The compound mould guide structure has the advantages of: 1, simple structure; 2, good using effect; and 3, high reliability.
Description
Technical field
The present invention relates to field of motor manufacturing, is a kind of compound mould guide structure for motor specifically.
Background technology
Electric machine rotor punching gangdie often many, the element precision of complex structure, flute profile drift require high, the gap is little; Some problems in use often take place in existing structure, and when working such as targeting part, retainer is often ejected guide pillar by spring; If retainer can not in time be got back to original position when next stroke began; Will cause damage to mould, even damage forcing press, so this design improves it emphatically.
Summary of the invention
For solving the problems of the technologies described above, the present invention provides a kind of compound mould guide structure for motor, can guarantee the correctness of retainer work in each stroke of mould, has avoided because of it breaks away from guide pillar the situation that mistake is done taking place.Concrete scheme is following:
A kind of compound mould guide structure for motor comprises guide pillar, retainer, guide pin bushing, ball, spring, pull bar, block, gland, cushion cover; Between said guide pillar and the retainer and adopt ball not have the gap between guide pin bushing and the retainer to cooperate; It between said guide pillar and the cushion cover cone match; Said spring is arranged on that guide pillar is outer, between cushion cover and retainer, guide pin bushing and cope match-plate pattern are fixed, cushion cover and lower bolster are fixed.
Be the problem that prevents that retainer from deviating from, be provided with porosely in the said guide pillar, be provided with pull bar in the hole; Said pull bar can slide up and down in said hole, and the lower end of said pull bar is provided with boss, and the upper end in said hole is provided with block; The internal diameter of said block is less than the diameter of said boss, and the upper end of said pull bar is provided with gland, and the diameter of said gland is greater than the internal diameter of retainer and less than the external diameter of retainer; For obtaining better technique effect, adopt welding method to fix between said guide pin bushing and the cope match-plate pattern.
Advantage of the present invention is:
1. simple in structure; 2. result of use is good; 3. reliability is high.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the retainer structure chart;
Fig. 3 is the small structure figure on the retainer.
Embodiment
Specify the present invention below in conjunction with accompanying drawing, as shown in Figure 1, the present invention includes guide pillar 2, retainer 3, guide pin bushing 1, ball 4, spring 5, pull bar 9, block 10, gland 11, cushion cover 6; Employing ball 4 no gaps cooperate between said guide pillar 2 and the retainer 3 and between guide pin bushing 1 and the retainer 3; Be cone match between said guide pillar 2 and the cushion cover 6; Said spring 5 is arranged on that guide pillar 2 is outer, cushion cover 6 and 3 of retainers, and guide pin bushing 1 is fixing with cope match-plate pattern 20, and cushion cover 6 is fixed with lower bolster 30.
Deviate from problem for solving retainer, be provided with porosely in the said guide pillar 2, be provided with pull bar 9 in the said hole; Said pull bar 9 can slide up and down in said hole; The lower end of said pull bar is provided with boss, and the upper end in said hole is provided with block 10, and the internal diameter of said block 10 is less than the diameter of said pull bar 9 lower end boss; The upper end of said pull bar 9 is provided with gland 11, and the diameter of said gland 11 is greater than the internal diameter of retainer 3 and less than the external diameter of retainer 3.
The structure of said retainer is as shown in Figure 2, and said retainer is a columniform tubular structure, has several rows can hold the aperture of said ball on the tube wall; The structure of aperture is as shown in Figure 3, the diameter of aperture greater than ball diameter 0.3mm about, the diameter of ball greater than retainer wall thickness 0.85mm about; Ball can freely roll therein; Put into aperture to ball, again an end of aperture with punching pin knock hole diameter around, make it distortion and be unlikely to ball and come off.Can guarantee that not having the gap cooperates between retainer and the guide pillar of guide pin bushing, edge ball like this.
For obtaining better technique effect, adopt welding method to fix between said guide pin bushing 1 and the cope match-plate pattern 20.
Operation principle of the present invention is: adopt ball not have the gap between guide pillar, retainer, the guide pin bushing and cooperate the assurance precision; For convenient disassembly, between guide pillar and the cushion cover cone match, the lower end is fixed on the lower bolster 30 with a plain washer and hex nut.Can repeatedly remove and install the assurance installation accuracy; In guide pillar, adorn a block, block is fixed in the guide pillar with a circlip for hole, and the block endoporus is joined a pull bar; Become matched in clearance between block and pull bar, pull bar is slided up and down in its hole play the guiding role, the effect of pull bar is to hold gland; Gland is fixed on the pull bar with circlip for shaft, and the external diameter of gland is greater than the external diameter of the internal diameter of retainer less than retainer, and the boss diameter of pull bar lower end is less than the diameter of bore of block; So the restriction retainer moves up and down within the specific limits; Be unlikely to deviate from, when retainer moved upward a fixed position, gland was promptly held by the pull bar in the guide pillar; After a stroke movement breaks away from retainer to guide pin bushing; Retainer since the effect of deadweight set back, thereby guaranteed the correctness of retainer work in each stroke of mould, avoided the situation that mistake is done taking place because of it breaks away from guide pillar.
Claims (2)
1. a compound mould guide structure for motor is characterized in that: comprise guide pillar, retainer, guide pin bushing, ball, spring, pull bar, block, gland, cushion cover; Between said guide pillar and the retainer and adopt ball not have the gap between guide pin bushing and the retainer to cooperate; It between said guide pillar and the cushion cover cone match; Said spring is arranged on that guide pillar is outer, between cushion cover and retainer, guide pin bushing and cope match-plate pattern are fixed, cushion cover and lower bolster are fixed; Be provided with porose in the said guide pillar; Be provided with pull bar in the hole, said pull bar can slide up and down in said hole, and the lower end of said pull bar is provided with boss; The upper end in said hole is provided with block; The internal diameter of said block is less than the diameter of said boss, and the upper end of said pull bar is provided with gland, and the diameter of said gland is greater than the internal diameter of retainer and less than the external diameter of retainer.
