Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Example

Referring to Figures 1-6, a machine tool slide structure includes a base 1, a first screw 2 is rotatably installed inside the base 1, the end of the first screw 2 is fixedly connected to an external power device, and the first screw 2 can be driven to rotate by the external power device, and a sliding block 3 is provided on the outer thread sleeve of the first screw 2, and the rotation of the first screw 2 can drive the sliding block 3 to slide along the length direction of the first screw 2. A fixed seat 4 is fixedly installed on the upper end surface of the sliding block 3, and the movement of the sliding block 3 can drive the movement of the fixed seat 4, and a second screw 5 is rotatably installed inside the fixed seat 4, and the end of the second screw 5 is fixedly connected to an external power device, and the second screw 5 can be driven to rotate by the external power device, and a support seat 6 is provided on the outer thread sleeve of the second screw 5, and the rotation of the second screw 5 can drive the support seat 6 to move along the length direction of the second screw 5.

The length direction of the first screw rod 2 and the length direction of the second screw rod 5 are arranged perpendicular to each other, and the first screw rod 2 and the second screw rod 5 can adjust the position of the support seat 6 in different directions on the horizontal plane. A bearing platform 7 is fixedly installed on the upper surface of the support seat 6. The movement of the support seat 6 will drive the bearing platform 7 to move. A shell 8 is rotatably installed inside the bearing platform 7. The movement of the bearing platform 7 can drive the shell 8 to move. One side of the shell 8 is connected to an external power device, and the shell 8 can be driven to rotate by the external power device. The upper part of the shell 8 is used to place the workpiece. The rotation of the shell 8 can drive the workpiece to rotate, and the angle of the workpiece can be adjusted as needed.

The outer side of the housing 8 is fixedly installed with a locking member, which can clamp the workpiece placed above the housing 8. The locking member includes a fixed block 16, which is fixedly arranged on the outer side of the upper end of the housing 8, and the fixed block 16 is distributed in a circumferential array along the outer edge of the housing 8. The end of the fixed block 16 is rotatably connected to a clamping frame 9 through an axle. The preferred shape and structure of the clamping frame 9 is shown in the accompanying drawings. A spring 10 is fixedly installed on the inner side of the lower end of the clamping frame 9 close to the housing 8. The end of the spring 10 away from the clamping frame 9 is fixedly connected to the housing 8. The spring 10 has an elastic pulling force on the lower end of the clamping frame 9. An adjusting member for adjusting the angle of the clamping frame 9 is also fixedly installed on the inner side of the housing 8. The angle of the clamping frame 9 can be adjusted by the adjusting member. When the upper end of the clamping frame 9 tilts toward one side of the housing 9, the clamping frame 9 can clamp the workpiece placed above the housing 8. A buffer pad is fixedly installed on the outer side of the upper end of the clamping frame 9. The inside of the buffer pad is made of a rubber structure. The buffer pad can be used to flexibly protect the workpiece and can play an anti-slip role.

The adjusting member includes a telescopic rod 15, a connecting plate 14 is fixedly installed on the upper end of the telescopic rod 15, and when the telescopic rod 15 is started, it can drive the connecting plate 14 to move up and down, and a connecting rod 13 is fixedly installed on the outer side of the connecting plate 14, and the up and down movement of the connecting plate 14 can drive the connecting rod 13 to move up and down, and a through hole 11 is opened on the side wall of the shell 8, and the end of the connecting rod 13 away from the connecting plate 14 extends through the outside of the through hole 11 and is fixedly installed with an adjusting frame 12, and the connecting rod 13 moves up and down inside the through hole 11 to drive the adjusting frame 12 to move up and down, and the outer side of the adjusting frame 12 contacts the inner surface of the clamping frame 9, and the adjusting frame 12 is a ring-shaped structure, and the up and down movement of the adjusting frame 12 can drive the inclination angle of the clamping frame 9 to change, which is located above the spring 10 and below the fixed block 16.

When the adjusting frame 12 moves upward, the adjusting frame 12 will push the clamping frame 9 upward, the spring 10 will be further stretched, and the upper end of the clamping frame 9 will tilt inward, so that the workpiece can be clamped. When the adjusting frame 12 moves downward, the lower end of the clamping frame 9 will tilt inward under the contraction of the spring 10 without the support of the adjusting frame 12. The support platform 7, the shell 8 and the adjusting frame 12 are all coaxially arranged. Since the center lines of multiple clamping frames 9 coincide with the central axis of the shell 8, when the adjusting frame 12 moves up and down, it will drive the clamping frames 9 to tilt at the same angle at the same time, which can ensure that the clamping frames 9 can be adjusted to the same angle at the same time, and the workpiece can be fixed in the center position, so that the workpiece and the shell 8 are in a coaxial position relationship, which can ensure the accuracy of the workpiece position. Then, the position of the workpiece in the horizontal direction can be adjusted by the first screw rod 2 and the second screw rod 5, so that the position of the workpiece can be accurately adjusted with high adjustment accuracy.

Working principle: During the operation of the machine tool slide structure, a cylindrical or tubular workpiece is placed vertically on the upper end surface of the shell 8. Starting the telescopic rod 15 can drive the connecting plate 14 to move upward, and the connecting plate 14 drives the adjusting frame 12 to move upward through the connecting rod 13. The upward movement of the adjusting frame 12 can push the lower end of the clamping frame 9 to tilt outward, and the spring 10 is further stretched. The upper end of the clamping frame 9 will continue to tilt inward until the workpiece is clamped and fixed. At this time, under the correction of the clamping frame 9, the workpiece and the shell 8 are in a coaxial position relationship, so that the workpiece is accurately fixed above the shell 8. By driving the first screw rod 2 or the second screw rod 5, the horizontal position of the workpiece can be accurately adjusted, which can facilitate the subsequent further operation of the machine tool on the workpiece.

The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and utility model concept of the utility model, shall be covered by the protection scope of the utility model.
