The outer side of the top of the outer wall of the slide rail 503 is slidably connected with the slide 504, and the slide 504 is used to drive the clamping spindle 506 to move. The side of one of the protrusions 501 is threadedly connected with a servo motor 505 through a flange, and the servo motor 505 is used to provide power to the first screw rod 502, so that the first screw rod 502 can rotate in the positive direction or the reverse direction. The tops of the two slides 504 are fixed. It is connected to a clamping spindle 506, which is used to center and clamp the shaft workpiece to be ground, and can drive the shaft workpiece to rotate with the rotation center of the clamping spindle 506 as the axis. An auxiliary component 507 is provided on one side of the front end of the two clamping spindles 506. The auxiliary component 507 is used to assist the staff in loading and unloading the shaft workpiece, so as to facilitate the clamping of the shaft workpiece to the inner side of the two clamping spindles 506, and the two auxiliary components 507 are symmetrical with each other with the center of the first screw rod 502 as the central axis. The two protrusions 501 are threadedly connected to the top front end of the base 1 by bolts.

[0019] In summary, when the outer wall of the shaft workpiece needs to be ground, the servo motor 505 can drive the first screw rod 502 to rotate on the inner side of the two protrusions 501. Since the outer wall of the first screw rod 502 is processed with completely opposite threads on both sides, when the first screw rod 502 rotates, it can simultaneously drive the two slides 504 connected to its threads to slide toward the center of the first screw rod 502, so that the distance between the two slides 504 can be adjusted, so that the distance between the two slides 504 is roughly the same as the distance required for the grinding process. The length of the shaft workpiece is the same, and then the shaft workpiece is placed on the top of the support rod 5075 in the auxiliary component 507. Through the operation of the cylinder 5073, the connecting plate 5074 can be driven to slide upward, thereby driving the support rod 5075 to rise through the connecting plate 5074, and the shaft workpiece placed on the top thereof can be lifted to the inner side of the two clamping spindles 506.

[0024] In this embodiment, preferably, the two clamping blocks 6086 are both made of rubber and have an arc-shaped groove on them. The specifications of the groove are the same as the curvature of the shaft to be ground. A clamping block 6086 with the same specifications as the curvature of the outer wall of the shaft to be ground can be selected according to the different specifications of the curvature of the outer wall of the shaft to be ground. The two clamping blocks 6086 are symmetrically arranged with the center of the fixed frame 6081 as the central axis.

[0025] In summary, after the shaft workpiece to be ground is clamped to the inner side of the clamping mechanism 5, a corresponding grinding belt machine is selected to grind it according to whether a keyway is provided on the shaft workpiece. If a keyway is not provided on the shaft workpiece to be processed, a traditional grinding belt 605 can be selected to grind it. After the traditional grinding belt 605 starts to work, the cylinder 2 6072 in the longitudinal moving member 607 installed at the bottom thereof also starts to work, and the slider 6074 is driven to slide forward by the cylinder 2 6072, thereby driving the fixed plate 6075 to slide forward together. Since the fixed plate 6075 is threadedly connected to the bottom end of the traditional grinding assembly by bolts, when the fixed plate 60 When the conventional grinding belt 605 slides forward, it can simultaneously drive the conventional grinding belt 605 to move together, so that the front bottom of the conventional grinding belt 605 is attached to the outer wall of the shaft workpiece. At the same time, the transmission box 601 located at the top of the base 1 near the control panel 3 starts to work, thereby driving the second screw rod 602 located at the rear end to start rotating. When the second screw rod 602 rotates, it can drive the slide 2 604 arranged at the bottom of the conventional grinding belt 605 to move, so that the shaft workpiece without a keyway can be ground. If the shaft workpiece to be ground has a keyway, the clamping grinding belt 606 is selected to grind it. First, by installing the clamping grinding belt 6 The operation of the longitudinal moving member 607 at the bottom of 06 drives the clamping type grinding belt 606 to move forward as a whole, so that the two clamping blocks 6086 in the clamping assembly 608 are on the same axis as the shaft workpiece to be ground. Through the operation of the cylinder three 6082, the upper slide plate 6083 can be synchronously driven to slide downward and the lower slide plate 6084 can slide upward. When the upper slide plate 6083 and the lower slide plate 6084 move, the clamping block 6086 fixed on the side thereof will be driven to move together, so that the clamping block 6086 can be attached to the outer wall of the shaft workpiece. Since the grinding belt at the front end of the clamping type grinding belt 606 is wound around the outer wall of the clamping block 6086 through a plurality of guide columns 6085, When the clamping block 6086 is attached to the outer wall of the shaft workpiece, the grinding belt will also be attached to the outer wall of the shaft workpiece. In this way, the grinding is not done at a point, but is transformed into grinding on a surface, thereby avoiding grinding off the edge of the keyway on the shaft workpiece. After the front end of the clamping grinding belt 606 is attached to the outer wall of the shaft workpiece with the keyway through the clamping assembly 608, the clamping grinding belt 606 starts to work, and drives the second screw 602 at the front end to rotate through the transmission box 601 located at the top of the base 1 away from the control panel 3, which can drive the slide 2 604 set at the bottom end of the clamping grinding belt 606 to move, thereby grinding the shaft workpiece with the keyway.

[0026] For example 3, please refer to Figure 1-Figure 13As shown, when the shaft grinding equipment for grinding shafts with keyways performs grinding processing on shaft workpieces with keyways, the sheet metal housing 2 is first opened, and then the shaft workpiece with keyways to be ground is placed on the top of the support rod 5075 in the auxiliary component 507, and the connecting plate 5074 is driven to rise by the cylinder 5073, thereby driving the support rod 5075 to move upward together, thereby assisting manual loading and unloading of the shaft workpiece, so that when the shaft workpiece is clamped, it is convenient to align it with the rotation center of the clamping spindle 506, and then clamp it. After the shaft workpiece is lifted up, the first screw rod 502 is driven to rotate by the servo motor 505, thereby synchronously driving the two clamping spindles 506. The shaft workpiece can be clamped by clamping both sides of the workpiece synchronously, and then the longitudinal moving components 607 in the grinding mechanism 6 cooperate with each other to enable the clamping abrasive belt 606 to move forward, and the clamping assembly 608 cooperates with each other to enable the clamping block 6086 to fit the outer wall of the shaft workpiece. Since the grinding belt of the clamping abrasive belt 606 is wound around the outer side of the clamping block 6086 through a plurality of guide columns 6085, grinding is not done at a point, but is transformed into grinding on a surface, thereby avoiding grinding off the edge of the keyway on the shaft. Finally, the second screw 602 is driven to rotate by the transmission box 601 to grind the outer wall of the shaft workpiece.
