[0002] Centerless grinding is also called centerless grinding, which is a kind of grinding process. There are two grinding wheels, the guide wheel and the grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the pad iron, and the grinding wheel grinds the workpiece. Centerless grinding belongs to the peripheral grinding method.

[0003] At present, in the centerless grinding process, open and close type clamping cylinders are often used, with a high degree of automation. The products of open and close type clamping cylinders are mature, have good effects in other fields, and are easy to assemble, use and replace.

[0004] However, in the on-site grinding environment of the centerless grinder, due to the large amount of dust, the open and close clamping cylinder is in direct contact with the workpiece and close to the dust, which causes the open and close clamping cylinder to wear out greatly. At the same time, the connecting rod and ball slider in the open and close clamping cylinder are easily worn and loosened, resulting in the open and close clamping cylinder having a relatively small clamping force and insufficient precision, which makes it difficult to meet the needs of heavy workpieces and workpieces that require precise adjustment. The failure rate is high, which in turn leads to a high cost of use.

[0005] Therefore, a manipulator clamping mechanism for centerless grinding is proposed. Utility Model Content

[0025] Among them, it should be supplemented that the dovetail slide bar 801 can slide on the bottom surface of the slider seat connecting plate 8 and the position of the dovetail slide bar 801 on the bottom surface of the slider seat connecting plate 8 is fastened by bolts. Among them, it should be supplemented that, through such a setting, the distance between the two clamping claw rods 802 can be conveniently adjusted, so as to clamp workpieces of different sizes, which is not affected by the length of the linear rail 4, and the applicability of the device is greatly improved. An inner T-shaped groove is provided on the side where the ladder block 6 contacts the ladder slider 702, and the side end of the ladder slider 702 that contacts the ladder block 6 is set to T-shape, and the side end of the ladder slider 702 extends into the inner T-shaped groove, so that the two side ends of the ladder slider 702 are always slidably connected with the inclined surfaces of the ladder blocks 6 located on both sides thereof.

[0026] Furthermore, the connecting rod 701 passes through the gap between the middle partition 302 and the two linear rails 4, and the front and back sides of the upper cover plate 3 are fixedly connected to the second side cover plate 303, thereby achieving a dustproof effect. An adjustment component is provided on the connecting plate 2: it includes an annular groove 205 opened on the connecting plate 2, a fine-tuning block 202 is fixedly connected to one side of the connecting plate 2, a U-shaped seat 203 is fixedly connected to the top surface of the upper cover plate 3 near the fine-tuning block 202, and both sides of the U-shaped seat 203 are threadedly connected with adjustable screws 204, and the fine-tuning block 202 protrudes between the adjustable screws 204 arranged on both sides of the U-shaped seat 203, and the connecting plate 2 and the upper cover plate 3 are fastened by a locking bolt 201, and the locking bolt 201 extends into the annular groove 205, and a notch 304 is provided on the top of the second side cover plate 303 near the locking bolt 201.

[0027] Through the arrangement and cooperation of the cylinder 7, the ladder block 6 and the ladder slider 702, etc., the ladder slider 702 is used to move up and down to drive the ladder blocks 6 on both sides thereof to move left and right, thereby successfully realizing the horizontal lateral clamping of the workpiece.

Through the arrangement of the adjustment components, the precise adjustment of the horizontal rotation of the clamped workpiece is successfully realized. It is easy to operate, has a wide range of applications, has a simple structural arrangement, is easy to maintain, has a low cost, and is suitable for popularization and use.

[0028] Working principle: When using this device, when it is necessary to clamp the workpiece used in the centerless grinding process horizontally, refer to Figure 1 As shown, it is only necessary to start the cylinder 7, and the output end of the control cylinder 7 will retract inward, thereby driving the connecting rod 701 to move upward, and causing the ladder slider 702 to move upward. Due to the sliding connection between the ladder block 6 and the ladder slider 702, the ladder blocks 6 on both sides of the ladder slider 702 will approach each other. At this time, the slider 5 slides on the linear rail 4, and the two slider seat connecting plates 8 approach each other, thereby causing the two clamping claw rods 802 to approach each other, thereby successfully achieving the tightening of the workpiece.

[0029] When the angle of the upper cover plate 3 needs to be adjusted, it is only necessary to loosen the locking bolt 201 through the notch 304. At this time, by rotating the adjustable screw 204, since the connecting plate 2 is fixedly connected to the vertical wall 1 of the manipulator and remains stationary, the upper cover plate 3 will rotate accordingly under the interaction of forces. At this time, the locking bolt 201 rotates in the annular groove 205. After the angle of the upper cover plate 3 is adjusted, it is only necessary to tighten the locking bolt 201. The precise adjustment of the horizontal rotation of the clamped workpiece is successfully achieved. The structural setting is simple and efficient, and is suitable for popularization and use.
