Abstract
The utility model relates to a press mounting clamping fixture for an automobile starter armatureaxle pressing in equipment, which comprises an upper press plate. The upper press plate is provided with an upper press head, the lower surface of the upper press plate is fixed with an upper clamping fixture, and a lower clamping fixture is arranged below the upper clamping fixture, and the lower clamping fixture is formed by connection of a base plate and a locating sleeve. The press mounting clamping fixture for an automobile starter armatureaxle pressing in equipment is characterized in that the upper clamping fixture is composed of a spring base, a lower press locating sleeve, pre-pressing head and a pre-pressing spring, wherein the spring base and the lower press locating sleeve are fixed at the lower end of the upper press plate in turn, the pre-pressing head which can slide up and down is arranged into the lower press locating sleeve, and the pre-pressing spring is arranged between an inner hole of the pre-pressing head and the spring base. The utility model has the advantages that that the actual press mounting basic standard guideline is a press mounting dimension from an armature drive end shaft step to an iron core lower end piece can be ensured, the pre-pressing spring can press the pre-pressing head and prevent the iron core rising when press mounting, thereby ensuring the product quality.
Description
Technical field
The utility model relates to a kind of mold that press-fits, and particularly a kind of automobile starter armature shaft is pressed into equipment and press-fits mold.
Background technology
In the automobile starter armature was made, axle was called axle assembly after press-fiting with iron core, realized that the equipment that axle assembly press-fits is that equipment is gone in axial compression.The mold that press-fits that equipment is gone in existing axial compression is to be made of last mold and following mold two parts, and mold is to be made of top board and the location pressure head that is fixed on the top board lower surface on it.This axial compression is gone into the press-fit approach of equipment with dististyle on the iron core and spacing realization of armature drive end axle step, and now part model product requirement to press-fit size must be drive end axle step and iron core lower surface size distance, will produce cumulative limit if re-use present press-fit approach, make armature drive end axle step can not get guaranteeing, thereby can't guarantee product quality to iron core lower surface size.
Summary of the invention
The purpose of this utility model is will provide a kind of automobile starter armature shaft to be pressed into equipment to press-fit mold, and this press-fits mold can guarantee that actual to press-fit benchmark be the press-fit size of armature drive end axle step to the iron core lower end-piece, thereby guarantees product quality.
The utility model is achieved in that it has a top board, on top board, be provided with seaming chuck, be fixed with mold at the top board lower surface, below last mold, be provided with mold down, following mold is to be formed by connecting by base and positioning sleeve, its special character is: described upward mold is by the spring base that is fixed on the top board lower end successively and presses down positioning sleeve, be located at and press down the interior and pre-pressure head that can slide up and down of positioning sleeve, and the pre-compressed spring that is located between pre-pressure head endoporus and the spring base constitutes.
Above-mentioned automobile starter armature shaft is pressed into equipment and press-fits mold, is fixed with stop collar on top board, and described seaming chuck is inserted in the stop collar, goes into the size that is pressed into of equipment to adjust axial compression.
The utility model has the advantages that: because last mold is not to act directly on the upper surface of armature core, but act on down on the upper surface of mold, so can guarantee that actual to press-fit benchmark be the press-fit size of armature drive end axle step to the iron core lower end-piece; Pre-compressed spring can press down pre-pressure head simultaneously, iron core fin when preventing to press-fit, thus guarantee product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model press-fits.
Among the figure: pre-pressure head 1 presses down positioning sleeve 2, pre-compressed spring 3, spring base 4, top board 5, centre pilot bar 6, seaming chuck 7, stop collar 8, armature shaft 9, iron core 10, positioning sleeve 11, base 12, base plate 13.
Embodiment
As shown in the figure, the utility model has a top board 5, on top board 5, be provided with and be pressed into the hole, corresponding its is pressed into the place, hole and is fixed with stop collar 8 on top board 5, go into the size that is pressed into of equipment to adjust axial compression, in stop collar 8, be fitted with hollow seaming chuck 7, the endoporus of seaming chuck 7 with wait to press-fit armature shaft 9 drive end spindle nose matched in clearance.Be fixed with mold at top board 5 lower surfaces, described upward mold is by the spring base 4 that is fixed on top board 5 lower ends by bolt successively and presses down positioning sleeve 2, be located at and press down the positioning sleeve 2 interior and hollow pre-pressure heads 1 that can slide up and down, and the pre-compressed spring 3 that is located between pre-pressure head 1 endoporus and the spring base 4 constitutes.Also be provided with in spring base 4 centers and be pressed into the hole, be provided with ring ladder pressing down positioning sleeve 2 endoporus middle part, be provided with annular shoulder, this annular shoulder and described ring ladder matched in clearance on the outer rim top of pre-pressure head 1; Described pre-pressure head 1 endoporus is the ladder place that shoulder hole and pre-compressed spring 3 lower ends are stuck in pre-pressure head 1 endoporus.Be provided with mold down below last mold, following mold is to be formed by connecting described positioning sleeve 11 endoporus and iron core to be installed 10 cylindrical matched in clearance by bolt by base 12 and the positioning sleeve 11 that is sleeved on the base 12.
During installation, following mold is gone into to axial compression on the base plate 13 of equipment with bolt, the oil hydraulic cylinder of again axial compression being gone into equipment is connected with top board 5 with seaming chuck 7 respectively with pneumatic cylinder.During use, iron core 10 is placed on down in the mold, armature shaft 9 commutation ends are put into iron core 10 holes, armature shaft 9 drive ends are gone into centre pilot bar 6 location of equipment with axial compression, and top board 5 and last mold press down under the effect of pneumatic cylinder, and pre-pressure head 1 is contact iron core 10 upper surfaces earlier, by the time press down positioning sleeve 2 contact with the positioning sleeve 11 of following mold implement after, seaming chuck 7 just under the effect of oil hydraulic cylinder, is pressed into armature shaft 9 in iron core 10 holes, finishes axle assembly and press-fits process.
Claims (2)
