Abstract

The invention discloses a shaft end blocking device. In the device, a fixture is arranged on a fixed block at the upper end of a positioning block I; springs are sleeved on guiding rods on the two sides of the fixed block; the lower ends of the springs are connected with the positioning block I; the upper ends of the springs are connected with a flange plate above the fixture; the lower end of the flange plate is connected with a positioning block II; the lower end of the positioning block II is connected with a blocking clamping fixture; a frustum-shaped slot, namely a pressing hole which is coaxial with the blocking clamping fixture is formed on the lower end face of the blocking clamping fixture towards the inside; the diameter of the upper part of the pressing hole is less than that of the lower part; and the upper end of the flange plate is connected with a piston rod of a press machine. The device has the advantages of simple structures and processes, high machining accuracy, high product quality and the like.

Description

A kind of shaft end blocking device
Technical field
The present invention relates to a kind of blocking device of shaft-like workpiece, relate in particular to a kind of device of vehicle dormer window motor drive shaft shaft end blocking.
Background technology
Development along with auto industry, people are more and more higher for the performance requirement of automobile, thereby the kind of auto parts and components is also thereupon more and more changeable, the vehicle dormer window motor drive shaft is under this background and produce, the Main Function of vehicle dormer window motor drive shaft is frictional force and the resistance that produces when reducing skylight motor rotation, thereby further reach the function that reduces noise, this axle is adding man-hour, shaft end blocking is one of important operation, what the shaft end blocking processing of existing this axle was adopted is special purpose machine tool, although special purpose machine tool can reach required precision, and the somewhat 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 shaft end blocking device that labour intensity is low.
The shaft end 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, be bolted the locating piece one of square shape on the workbench of forcing press, the center, upper end of locating piece one is bolted and is used for the square shape fixed block of support hydraulic cutting ferrule, fixed block is provided with the shaft-like workpiece jig, described jig is substantially same as the 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; Be socketed spring on the guide post, the lower end of spring links to each other with locating piece one, the upper end of spring links to each other with the ring flange of described jig top, this ring flange is substantially same as the 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 described ring flange is bolted to support the square shape locating piece two of blocking mold, the center, lower end of locating piece two is bolted the blocking mold, this blocking mold is cylinder, offer coaxial with the blocking mold and corresponding with locating piece two screw to inside by the upper surface of blocking mold, the frustum-like shape slotted eye coaxial with the blocking mold offered in lower surface by the blocking mold to inside, namely press the hole, 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 finishes shaft end blocking like this:
During installation, at first to determine according to the size of axle head the pressure hole dimension of blocking mold, guarantee to press the lower diameter in hole greater than the diameter of axle head, press the upper diameter in hole 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, then adjust the impulse stroke of blocking mold by the piston rod of forcing press, ball is put into the hole of axle head, the starting pressure machine, the piston rod of forcing press moves downward pressurization, piston rod drives ring flange, 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 enters in the pressure hole of blocking device, because axial pressure, and press the lower diameter in hole greater than the diameter of axle head, press the upper diameter in hole less than the axle head diameter, 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, reach the purpose of blocking, because the effect of ring flange both sides spring, after blocking is complete, ring flange auto-returned original position is returned thereby drive the blocking mold; Add man-hour, determine according to the size of ball and stub bore the pressure hole depth of blocking mold, guarantee in whole process, can not hurt the surface of ball.
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, technique are simple, and machining accuracy is high, good product quality, high efficiency.
Description of drawingsFig. 1 is that master of the present invention looks schematic diagram.
Fig. 2 is that the master of blocking mold of the present invention looks generalized section.
The specific embodimentAs shown in Figure 1, be bolted locating piece 2-1 on the workbench 1 of forcing press, the center, upper end of locating piece 2-1 is bolted fixed block 3, 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 namely 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, 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, the center, lower end of ring flange is bolted locating piece 2-2, the center, lower end of locating piece 2-2 is bolted blocking mold 8, 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 cylinder, offers the screw 10 coaxial with the blocking mold to inside by the upper surface of blocking mold, offers the frustum-like shape slotted eye coaxial with the blocking mold to inside by the lower surface of blocking mold, namely press hole 11, press the upper diameter in hole less than lower diameter.
