Abstract
The invention discloses a plug-in sliding fork grinding and excircle processing technique. The technique comprises the following steps: (1) mounting a conical grinding wheel on a grinder, ensuring the revolution axes of the grinding wheel and a sliding fork to form an included angle which is greater than 0 degree and less than 90 degrees, and simultaneously ensuring the bus of the grinding wheel to be parallel to the revolution axis of the sliding fork, wherein the bus length of the grinding wheel is greater than or equal to the axial length of the ground surface of the rod part of the sliding fork; and (2) mounting and clamping the sliding fork, starting the grinding wheel and the sliding fork to rotate respectively, carrying out radial feed on the grinding wheel along the sliding fork, and grinding the ground surface of the rod part of the sliding fork by virtue of the conical surface of the grinding wheel. According to the invention, by adopting the processing technique, on the premises of not increasing the equipment and manpower input, the surface quality of the excircle of the rod part of the sliding fork is improved, and the production efficiency is also improved.
Description
Technical field
The invention belongs to machining manufacturing technology field, be specifically related to a kind of plug-in type slip yoke grinding cylindrical processing technology.
Background technology
As shown in Figure 1, the plug-in type slip yoke 1 of passenger car driving-shaft assembly with the car load junction, use the oil sealing 2 that cooperates with slip yoke 1 cylindrical to seal, a lot of drivers or car owner are reflected in these faying face 3 places and oil leakage phenomenon occurs, malfunction elimination finds that main cause is: as shown in Figure 2, slip yoke 1 cylindrical adds the processing texture 4 that occurs paralleling to the axis man-hour, when power transmission shaft rotates at a high speed, lubricating oil in the oil sealing 2 has certain oil pressure, because the existence of the processing texture 4 that parallels to the axis, lubricating oil in the oil sealing 2 is thrown away from processing texture 4, and sealing effectiveness is bad.
Trace to its source, the formation of processing texture 4 comes from the processing technology of slip yoke 1 grinding cylindrical, as shown in Figure 3, traditional slip yoke 1 grinding cylindrical technology is to use the cylinder emery wheel 5 perpendicular to workpiece to carry out grinding, the axis of rotation 6 of emery wheel 5 is parallel with the axis of rotation 7 of slip yoke 1, in process, because emery wheel 5 width are often less than the width of processed slip yoke 1 cylindrical machined surface, because the axial length that is ground cylindrical of slip yoke 1 bar portion is 145mm, and the greatest axial length of the domestic produced cylinder emery wheel of emery wheel manufacturing firm is 125mm, so at grinding process medium plain emery wheel 5 existing radial feeds to satisfy the diameter dimension requirement, also there is axial feed to satisfy width requirement, though the roughness of workpiece is very low, but in process because the processing texture 4 that parallels to the axis that the axial feed of emery wheel 5 causes makes faying face 3 places of slip yoke 1 cylindrical and oil sealing 2 that rough and uneven in surface point be arranged, power transmission shaft is when rotating at a high speed, lubricating oil is thrown out of from processing texture 4, can not satisfy seal request.If with emery wheel 5 axial length when being increased to more than or equal to 145mm, the volume of emery wheel 5 increases, emery wheel is easy to generate defective in manufacture process, can not guarantee the roughness of workpiece.
Summary of the invention
The present invention provides a kind of plug-in type slip yoke grinding cylindrical processing technology that is not prone to the processing texture at the slip yoke outer round surface in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: plug-in type slip yoke grinding cylindrical processing technology, may further comprise the steps,
⑴, conical emery wheel is installed on grinding machine, the axis of rotation of emery wheel and slip yoke axis of rotation are greater than 0 ° and less than 90 ° angle, the bus of guaranteeing emery wheel simultaneously is parallel with the axis of rotation of slip yoke, and the bus length of emery wheel is ground the axial length of face more than or equal to slip fork arm portion;
⑵, clamping slip yoke start emery wheel and slip yoke and rotate respectively, and emery wheel is along the radial feed of slip yoke, and the conical surface of emery wheel carries out grinding to the face that is ground of slip fork arm portion.
Adopt technique scheme, the axis of rotation of conical emery wheel and slip yoke axis of rotation are greater than 0 ° and less than 90 ° angle, can under the prerequisite that does not increase the emery wheel axial length, increase the width of wheel grinding contact-making surface like this, the volume of emery wheel is little, and the bonding force of the grains of sand can reach the requirement of rotation at a high speed; The bus length of emery wheel is realized the direct grinding of emery wheel radial feed more than or equal to the axial length that slip fork arm portion is ground face, no longer include axial feed, like this when having guaranteed roughness, also avoided the appearance of the processing texture that parallels to the axis, slip yoke cylindrical and oil sealing faying face sealing property are improved, guarantee that oil leakage phenomenon no longer takes place.The present invention adopts this kind processing technology under the prerequisite that does not increase equipment and human input, has improved the surface quality of slip fork arm portion cylindrical, has also improved production efficiency.

The specific embodiment
As Fig. 4, shown in Figure 5, plug-in type slip yoke grinding cylindrical processing technology of the present invention may further comprise the steps:
⑴, conical emery wheel 5 is installed on grinding machine, the axis of rotation 6 that makes emery wheel 5 and the axis of rotation 7 of slip yoke 1 are greater than 0 ° and less than 90 ° included angle A, the bus 8 of guaranteeing emery wheel 5 simultaneously is parallel with the axis of rotation 7 of slip yoke 1, and bus 8 length of emery wheel 5 are ground the axial length of face more than or equal to slip yoke 1 bar portion;
⑵, clamping slip yoke 1 start emery wheel 1 and slip yoke 5 and rotate respectively, and emery wheel 5 is along the radial feed of slip yoke 1, and the conical surface of emery wheel 1 carries out grinding to the face that is ground of slip yoke 1 bar portion.
The present invention can increase the width of emery wheel 5 Grinding Contact faces under the prerequisite that does not increase emery wheel 5 axial lengths, bus 8 length of emery wheel 5 realize the direct grinding of emery wheel radial feed more than or equal to the axial length that slip yoke 1 bar portion is ground face, no longer include axial feed, like this when having guaranteed roughness, also avoided the appearance of the processing texture 4 that parallels to the axis, the faying face sealing property of slip yoke 1 cylindrical and oil sealing 2 is improved, guarantee that oil leakage phenomenon no longer takes place.The present invention adopts this kind processing technology under the prerequisite that does not increase equipment and human input, has improved the surface quality of slip yoke 1 bar portion cylindrical, has also improved production efficiency.
The grinding operation that can carry out axial end of the emery wheel 5 that uses in the middle of the present invention during the mill axial end, is used the right wedge angle part of Fig. 4 medium plain emery wheel 5, and this has also increased the function of grinding machine.
