Abstract
The invention relates to a processing tooling, in particular to a parts processing tooling of a speed reducer, belonging to the technical field of processing toolings. According to the technical scheme provided by the invention, the parts processing tooling of the speed reducer comprises a three-jaw chuck, wherein all the jaws of the three-jaw chuck are provided with pressure adjusting springs. According to the parts processing tooling of the speed reducer, a planetary gear is connected in a fastening manner with the three-jaw chuck by the pressure adjusting springs, so that the problem of unstable stress of the planetary gear if the planetary gear is directly clamped by the three-jaw chuck is solved; the problem of center bias caused by a way that the planetary gear is directly clamped by the three-jaw chuck is solved by using pressure adjusting springs of a fuel injector, the rigidity of the pressure adjusting spring is 200N/mm, and the excircle of the pressure adjusting spring is subjected to abrasive machining; as the elasticity of the pressure adjusting springs cannot cause damage to the parts and the clamping effect can be realized as well, the pressure adjusting springs are adopted as fixtures, so that the cost is greatly saved; the fixtures have commonality, so that the pressure adjusting springs of the same type are all suitable for gears in a certain range; and the parts processing tooling of the speed reducer is simple and compact in structure, convenient to mount and use, safe and reliable, and is favorable for improving the processing quality and reducing the processing cost.
Description
Technical field
The present invention relates to a kind of processing tool, especially a kind of reductor part processing frock belongs to the technical field of processing tool.
Background technology
Along with the develop rapidly of mechanical processing industry, the required precision of reductor is also increasingly high.The Gear Planet Transmission reductor is the especially demanding reductor type of a kind of precision; Its involved gear ring, planetary gear, planet carrier all have very high required precision; Under the prerequisite that these part precision guarantee, fluency, low noise, the high life that just can accomplish the transmission of whole reductor.About planetary gear, because its matching requirements, its endoporus need adopt the mill processing technology.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of reductor part processing frock is provided, it is simple and compact for structure, and is easy to install, improves crudy, cuts down finished cost, and applicability is good, and is safe and reliable.
According to technical scheme provided by the invention, said reductor part processing frock comprises scroll chuck, and pressure spring all is set on the claw of said scroll chuck.
Said pressure spring is positioned at planetary teeth groove, and the external diameter and the teeth groove of said pressure spring are complementary; Planetary gear is fastenedly connected through pressure spring and scroll chuck.
Center in the said planetary gear is provided with endoporus; Planetary gear grinds processing to planetary endoporus after being fastenedly connected through pressure spring and scroll chuck.
The rigidity of said pressure spring is 200N/mm, and the external diameter of pressure spring is 15mm.The aperture of the corresponding endoporus of said planetary gear is 83mm.
Advantage of the present invention: planetary gear is fastenedly connected through pressure spring and scroll chuck, if solved the direct problem that clamps stressed shakiness with scroll chuck of planetary gear; Solved planetary gear directly use scroll chuck clamp the generation center inclined to one side for problem adopts spring for fuel injector, rigidity is at 200N/mm, peripheral milling processing is because the elasticity of pressure spring can not play the effect of clamping again to part product destruction; Adopt pressure spring as anchor clamps, practiced thrift cost greatly; Anchor clamps have versatility, all are suitable for the gear of a pressure spring to certain limit; Simple and compact for structure, easy to install, improve crudy, cut down finished cost, safe and reliable.
Description of drawings
Fig. 1 is the planetary structural representation of the present invention.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
Like Fig. 1 ~ shown in Figure 3: the present invention includes scroll chuck 1, pressure spring 2, planetary gear 3, endoporus 4 and teeth groove 5.
Like Fig. 1, Fig. 2 and shown in Figure 3: the centers in the said planetary gear 3 are provided with the endoporus 4 that connects planetary gear 3, and the outer ring of planetary gear 3 is provided with some teeth groove 5.In order to grind processing to the endoporus 4 of planetary gear 3, improve processing processing, said planetary gear 3 is put into scroll chuck 1.Said scroll chuck 1 has claw symmetrically; Pressure spring 2 all is set on the claw of scroll chuck 1; Said pressure spring 2 is positioned in the teeth groove 5 of planetary gear 3, and planetary gear 3 is clamped on the scroll chuck 1 through pressure spring 2, thereby can install and fix planetary gear 3.The axis of the axis of planetary gear 3 and scroll chuck 1 is located along the same line.The rigidity of pressure spring 2 is at 200N/mm, and the cylindrical of pressure spring 2 adopts mill processing, and the elasticity through pressure spring 2 can make planetary gear 3 and scroll chuck 1 chucking can not destroy simultaneously to planetary gear 3.Aperture with planetary gear 3 corresponding endoporus 4 is 83mm, error for+0.043 or+0.023mm is an example, the cylindricity of planetary gear 3 corresponding endoporus 4 is 0.011mm; Roughness is Ra0.4; At this moment, the external diameter of pressure spring 2 is 15mm, so that pressure spring 2 can be complementary with teeth groove 5.When processing the planetary gear 3 of different size, according to teeth groove 5 sizes of planetary gear 3, corresponding pressure spring 2 external diameters are set, can guarantee planetary gear 3 clamping actions.
Like Fig. 1 ~ shown in Figure 3: during use, in the teeth groove 5 of planetary gear 3 pressure spring 2 is set, planetary gear 3 is fastenedly connected through pressure spring 2 and scroll chuck 1, and the axis of the axis of planetary gear 3 and scroll chuck 1 is located along the same line, and guarantees concentricity.Behind the chucking, the endoporus 4 of planetary gear 3 is ground processing.
