Abstract
The utility model provides a work piece supporting mechanism for high-speed grinding machine of valve stem processing, it can solve that the supporting mechanism installation space demand is great, is difficult to satisfy the technical problem of customer's demand. The utility model provides a work piece supporting mechanism for high-speed grinding machine of valve stem processing, high-speed grinding machine include work piece axle and emery wheel, and work piece supporting mechanism includes the end face supporting shoe, its characterized in that: the workpiece supporting mechanism further comprises an oil cylinder, the end face supporting blocks and the grinding wheel are respectively arranged on the left side and the right side of the workpiece shaft, the end face supporting blocks are mounted at the output end of a piston rod of the oil cylinder, and the piston rod of the oil cylinder is obliquely arranged towards the upper right. The mechanism can realize that the part to be processed of the workpiece is bent relative to the non-processing part and has a springback effect, so that the end face supporting block can effectively support the workpiece in the processing process, and further the traditional servo motor and the speed reducer are replaced, and the requirement on installation space is reduced.
Description
Technical Field
The utility model relates to a grinding machine technical field especially relates to a grinding machine for valve stem processing, concretely relates to work piece supporting mechanism for high-speed grinding machine of valve stem processing.
Background
The body of the valve stem is thin, and a supporting mechanism is required to support the valve stem in the grinding process, so that the workpiece is prevented from deviating. Because the work piece is at the grinding in-process, the size diminishes, current supporting mechanism need be through servo motor and reduction gear transmission in order to adjust the support point of end face supporting shoe, ensure the effective support to the work piece, but the setting of servo motor and reduction gear can lead to the whole installation space demand of supporting mechanism great, is difficult to satisfy the customer to the miniaturized special demand of grinding machine.
SUMMERY OF THE UTILITY MODEL
The utility model provides a work piece supporting mechanism for high-speed grinding machine of valve stem processing, it can solve that the supporting mechanism installation space demand is great, is difficult to satisfy the technical problem of customer's demand.
The utility model provides a work piece supporting mechanism for high-speed grinding machine of valve stem processing, high-speed grinding machine include work piece axle and emery wheel, work piece supporting mechanism includes the terminal surface supporting shoe, its characterized in that: the workpiece supporting mechanism further comprises an oil cylinder, the end face supporting blocks and the grinding wheels are respectively arranged on the left side and the right side of the workpiece shaft, the end face supporting blocks are mounted at the output end of a piston rod of the oil cylinder, and the piston rod of the oil cylinder is obliquely arranged towards the upper right side.
Furthermore, the end face supporting block is provided with a V-shaped positioning groove matched with the workpiece.
Furthermore, the oil cylinder is fixed on the mounting plate and is arranged in the housing, the output end of the oil cylinder is connected with the housing, the housing is in sealing fit with the mounting plate, and the end face supporting block is arranged on the outer side of the housing.
The utility model discloses a work piece supporting mechanism, on the one hand, can realize taking place to buckle and have the rebound effect with the position of waiting to process of work piece for non-processing position, because the size of waiting to process the position is dwindled gradually in the abrasive machining process, the position of waiting to process after reducing is supported, contacted with the terminal surface supporting shoe all the time under the rebound effect, can realize effectively supporting the work piece, because the hydro-cylinder is for traditional servo motor, speed reducer, the volume is littleer, can effectively reduce the whole installation space demand of supporting mechanism, and then satisfy the special demand of customer to the grinding machine miniaturization; on the other hand, the direction of the supporting force of the supporting mechanism to the workpiece is obliquely arranged towards the right upper side, the supporting force can be decomposed into horizontal right and vertical upward component forces, wherein the vertical upward component force of the supporting force is balanced by the vertical downward cutting force generated by the grinding wheel, and the horizontal rightward component force of the supporting force is balanced by the horizontal leftward abutting force generated by the grinding wheel, so that the stress balance of the workpiece is realized, and the stability of the workpiece is ensured.
Drawings

Fig. 2 is a schematic structural diagram of the workpiece support mechanism of the present invention, in which the end face support block and the housing are omitted.
Detailed Description
A workpiece supporting mechanism for a high-speed grinding machine for machining a valve rod is disclosed, as shown in fig. 1 and fig. 2, the high-speed grinding machine comprises a workpiece shaft 21 and a grinding wheel 31, a clamp 22 is mounted at the end part of the workpiece shaft 21, a workpiece to be machined, namely a valve rod W, is mounted on the clamp 22, the workpiece supporting mechanism comprises an end face supporting block 11, the workpiece supporting mechanism further comprises an oil cylinder 12, the end face supporting block 11 and the grinding wheel 31 are respectively arranged at the left side and the right side of the workpiece shaft 21, the end face supporting block 11 is mounted at the output end of a piston rod of the oil cylinder 12, and the; specifically, the end face supporting block 11 is provided with a V-shaped positioning groove matched with a workpiece, the oil cylinder 12 is fixed on the mounting plate 14 and is arranged in the housing 13, the output end of the oil cylinder 12 is connected with the housing 13, the housing 13 is in sealing fit with the mounting plate 14, the end face supporting block 11 is arranged on the connecting block 15 outside the housing 13, guide rails parallel to a piston rod of the oil cylinder are arranged on two sides of the oil cylinder respectively, each guide rail comprises an inner guide rail and an outer guide rail, the inner guide rail is fixedly connected with the mounting plate, the outer guide rail is fixedly connected with the housing, the housing and the piston rod synchronously move and are guided by the inner guide rail and the outer guide.
The utility model discloses a work piece supporting mechanism theory of operation as follows, because under the effect of hydro-cylinder, the end face supporting shoe acts on the position of waiting to process of work piece, make the position of waiting to process of work piece take place to buckle and have the rebound effect for non-processing position, in the abrasive machining in-process, because the size of waiting to process the position is dwindled gradually, the position of waiting to process after reducing supports with the end face supporting shoe all the time under the rebound effect, the contact, can realize the effective support to the work piece, and simultaneously, the size of waiting to process the position reduces, the in-process of resilience, the range of buckling of waiting to process the position also dwindles gradually, the rebound effect reduces gradually promptly, when abrasive machining finishes, the bending recovery of processing position, no longer have the rebound effect, can avoid the work piece.
