Description
Technical field
The utility model relates to the tool-type mold that a kind of machinery manufacturing industry is used, the mold of the conjuncted multiaxis spare in particularly a kind of alignment plane.
Background technology
Planet pin is the key component in the automobile differential, and except that dimension precision requirement was higher, its position accuracy demand was also very high, and manufacture difficulty is bigger.Planet pin is decussate texture, divides the axle that is listed in four sides that a shape, measure-alike is installed respectively, but the opposing planetary gear of direction.The planetary back side is sphere, and this sphere cooperates with corresponding Internal Spherical Surface on the differential carrier, and its fit quality directly influences planetary gear and the axle shaft gear meshing quality that matches.If axiality, perpendicularity and flatness are overproof between four axles of the planet pin of processing, must worsen assembly quality, increase rotational noise, reduce service life.
What in the planet pin manufacture process quality is had the greatest impact is heat treatment step, and the conjuncted multiaxis spare in this kind plane leaves residual deformation inevitably after heat treatment.Being out of shape overproof is defective work, and prior art mainly realizes finishing shape by smoothing and alignment technical measures, to reach designing quality.Prior art is easy to realize that with four contour V shape iron support planetary gears axle smoothings flatness is up to standard.And alignment is not easy to operate, and alignment is of low quality.The prior art alignment of exerting pressure on two contour V shape iron Zhi Hangxing gear shafts, although this coalignment simple possible, in case the axis disalignment of pressure of exerting pressure and planet pin, planet pin overturns in V shape iron and causes correction inaccurate.Improper as if exerting pressure in alignment process, even cause planet pin from V shape iron, to eject.Generally speaking, the technology of existing alignment planet pin is undesirable, and work efficiency is low, alignment is of low quality, security is bad, the alignment demand that is not suitable for producing in enormous quantities.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, spacing accurately, processing ease, process safety, the limit-type alignment mold of the conjuncted multiaxis spare in the plane that the alignment quality is good, efficient is high.
The utility model is achieved through the following technical solutions technical goal.
The limit-type alignment mold of the conjuncted multiaxis spare in plane, it comprises dies holder, outer support, upper limit position block, pressure head, horizontal limited block, compensation pad, interior support and lower position block.Described dies holder is the inverted T-shape member, be positioned at the bottom base plate with on the vertically-arranged wallboard vertical mutually, corresponding workpiece both ends horizontal shaft part is provided with contour outer support and interior support on the base plate, hypomere fixedly connected upper limit position block of difference and lower position block on the corresponding workpiece vertical pivot of wallboard inner face, the fixedly connected horizontal limited block in wallboard right side, middle part is on the right axle head of workpiece.Described pressure head is positioned on the wallboard of dies holder, and its axis is coaxial with the workpiece longitudinal axis.Its improvements are: described outer the support at workpiece left side axle head, and interior support is propped up at the right axle of workpiece root, and the height of outer support and interior support equals the design length of the horizontal shaft part outer wall of workpiece to the longitudinal axis bottom face.Described upper limit position block is parallel with the lower position block medial surface relatively, is spaced apart the shaft diameter value of workpiece between the two.Described horizontal limited block is filled in the prosthetics pad towards the lower surface to workpiece between the right axle head outer wall.
In the said structure, the lateral cross section of outer support, upper limit position block, horizontal limited block, compensation pad, interior support and lower position block is rectangle.
The utility model compared with prior art has following good effect:
1, stake formula position limiting structure is simple, makes easily;
2, alignment under spacing condition, easy to operate, quality controllable, alignment efficient height;
3, under spacing condition, exert pressure, pressure and workpiece longitudinal axis coaxial line, alignment process is steady, and the possibility that workpiece does not eject from mold is so security is good.
Description of drawings
Fig. 1 is that the utility model structure master looks schematic diagram.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
The limit-type alignment mold of the conjuncted multiaxis spare in plane shown in Figure 1, it comprises dies holder 1, supports 2 outward, upper limit position block 3, pressure head 4, horizontal limited block 5, compensation pad 6, interior support 7 and lower position block 8.The utility model embodiment alignment workpiece is the planet pin in the automobile differential, and this part is cross, four fulcrum places at grade, supporting for it dies holder 1 is the mold main component.The dies holder 1 likeness in form word of falling T, the base plate that is positioned at the bottom with on the wallboard of vertically-arranged vertical mutually, corresponding workpiece 9 both ends horizontal shaft parts are provided with contour outer support 2 and interior support 7 on the base plate, and this highly equals the design length of workpiece 9 horizontal shaft part outer walls to the longitudinal axis bottom face.The wallboard inner face of dies holder 1 vertically-arranged, hypomere fixedly connected upper limit position block 3 of difference and lower position block 8 on corresponding workpiece 9 vertical pivots.The horizontal limited block 5 that the right side, wallboard middle part of dies holder 1 connects is on the workpiece 9 right axle heads.Described pressure head 4 is the end of exerting pressure of forcing press, and is removable up and down, and regular situation push-down head 4 is positioned on the wallboard of dies holder 1, and its axis is coaxial with workpiece 9 longitudinal axis.The utility model is provided with the shaft part of pilework restriction workpiece 9 from four direction on dies holder 1, support 2 outward at workpiece 9 left axle heads, in support 7 at workpiece 9 a right root, contour outer support 2 and interior support 7 make workpiece 9 both ends horizontal axle places at grade.Although upper limit position block 3 and lower position block 8 are in up and down two ends, both medial surfaces are parallel relatively, between be spaced apart the shaft diameter value of workpiece 9.Workpiece 9 is installed in the cross position limiting structure of being made up of outer support 2, interior support 7 and upper limit position block 3, lower position block 8, pretending according to the gap plug of the horizontal limited blocks 5 of the right axle of workpiece 9 should thick compensation pad 6, the compensation pad 6 of plug dress is eliminated the gap, location that workpiece 9 produces because of distortion, workpiece 9 is among the full position limiting structure, start that pressure head 4 is descending exerts pressure to workpiece 9, the flexural deformation of workpiece 9 horizontal shaft parts obtains correcting in position limiting structure.Then workpiece 9 is turned installation, repeat the quality that above-mentioned alignment operation can obtain to adhere to specification.
The utility model alignment in full position limiting structure, except that easy and simple to handle, quick, quality well, guarantee that also workpiece 9 does not eject from mold, so security is good.
