Description

A kind of axle head blocking device
Technical field
The present invention relates to a kind of blocking device of shaft-like workpiece, relate in particular to the device of a kind of vehicle dormer window motor drive shaft axle head blocking.
Background technology
Along with the continuous development of auto industry, people are increasingly high for the performance requirement of automobile, thereby the kind of auto parts and components is also more and more changeable thereupon; The vehicle dormer window motor drive shaft is under this background and produce, and the main effect of vehicle dormer window motor drive shaft is frictional force and the resistance that produces when reducing skylight motor rotation, thereby further reaches the function that reduces noise; This axle is adding man-hour, and the axle head blocking is one of important operation, and what existing this axle head blocking processing was adopted is special purpose machine tool; Though special purpose machine tool can reach required precision; But the expensive of this lathe, for all enterprises, the special purpose machine tool that blocking is used is also inapplicable.
Summary of the invention
The object of the present invention is to provide a kind of machining accuracy high, save production cost, installation and maintenance is convenient, long service life, the axle head blocking device that labour intensity is low.
The axle head blocking device that the present invention relates to is mounted in the piston rod of forcing press and the device between the workbench; Comprise locating piece, jig, fixed block, guide post, spring, blocking mold and ring flange; Through the block locating piece one of bolt connection side, the center, upper end of locating piece one connects through bolt and is used for the square shape fixed block of support hydraulic cutting ferrule on the workbench of forcing press, and fixed block is provided with the shaft-like workpiece jig; Said jig is basic identical with prior art; For improving machining accuracy, clamping is firm, and this jig is preferably the hydraulic pressure cutting ferrule; The upper surface of above-mentioned locating piece one and the both sides of fixed block respectively are provided with vertical straight-bar, i.e. a guide post; Socket spring on the guide post; The lower end of spring links to each other with locating piece one, and the upper end of spring links to each other with the ring flange of said jig top, and this ring flange is basic identical with prior art; Be that the through hole of the ring flange both sides passed of guide post and the lower end of ring flange link to each other with spring; The center, lower end of said ring flange connects the square shape locating piece two that is used for supporting the blocking mold through bolt, and the center, lower end of locating piece two connects the blocking mold through bolt, and this blocking mold is a cylinder; Offer coaxial with the blocking mold and corresponding screw by the upper surface of blocking mold to inside with locating piece two; The frustum-like shape slotted eye coaxial with the blocking mold offered to inside in lower surface by the blocking mold, promptly presses the hole, and this upper diameter of pressing the hole is less than lower diameter; The upper end of above-mentioned ring flange links to each other with the piston rod of forcing press.
The present invention accomplishes the axle head blocking like this:
During installation, at first will confirm the pressure hole dimension of blocking mold according to the size of axle head, guarantee to press the diameter of the lower diameter in hole greater than axle head, the upper diameter of pressing the hole is less than the axle head diameter; Its less important assurance jig and blocking mold be in coaxial line, add man-hour, at first utilize jig with axis clamping, and guarantee the dead in line of axle and blocking device; The impulse stroke of the adjustment of the piston rod through forcing press blocking mold is then put into the hole of axle head with ball, the starting pressure machine, and the piston rod of forcing press moves downward pressurization; Piston rod drives ring flange, and ring flange drives the pressurization of blocking mold, extrusion spring when ring flange moves downward; When reaching the impulse stroke of blocking mold, axle head gets in the pressure hole of blocking device, because axial pressure; And press the diameter of the lower diameter in hole greater than axle head, the upper diameter of pressing the hole is less than the axle head diameter, and then the blocking mold dwindles the hole of axle head generation radial pressure with axle head; Then ball is stuck in the inside in hole, reaches the purpose of blocking, because the effect of ring flange both sides spring; After blocking finished, the automatic correcting action of ring flange returned thereby drive the blocking mold; Add man-hour, confirm the pressure hole depth of blocking mold, guarantee in the whole machining process process, can not hurt the surface of ball according to the size of ball and stub bore.
The present invention compared with prior art has and saves production cost, and installation and maintenance is convenient, long service life, and simple operation, labour intensity hangs down advantage.
The present invention also has following advantage: structure, technology are simple, and machining accuracy is high, good product quality, high efficiency.
Description of drawingsFig. 1 looks sketch map for master of the present invention.
Fig. 2 looks generalized section for the master of blocking mold of the present invention.
The specific embodimentAs shown in Figure 1, connect locating piece 2-1 through bolt on the workbench 1 of forcing press, the center, upper end of locating piece 2-1 connects fixed block 3 through bolt, and fixed block is provided with hydraulic pressure cutting ferrule 4; The upper surface of locating piece 2-1 and the both sides of fixed block respectively are provided with a vertical straight-bar, and promptly guide post 5; Socket spring 6 on the guide post; The lower end of spring links to each other with locating piece 2-1; The upper end of spring links to each other with the ring flange 7 of hydraulic pressure cutting ferrule top, and the through hole of the ring flange both sides that guide post passes and the lower end of ring flange link to each other with spring, and the center, lower end of ring flange connects locating piece 2-2 through bolt; The center, lower end of locating piece 2-2 connects blocking mold 8 through bolt, and the upper end of ring flange links to each other with the piston rod of forcing press 9.
As shown in Figure 2; Blocking mold 8 is a cylinder, offers the screw 10 coaxial with the blocking mold by the upper surface of blocking mold to inside, offers the frustum-like shape slotted eye coaxial with the blocking mold by the lower surface of blocking mold to inside; Promptly press hole 11, the upper diameter of pressing the hole is less than lower diameter.
