Technical Field

[0001] The invention relates to the technical field of gantry slides, in particular to a gantry slide double-balance and double-drive direct-push drive structure. Background Art

[0002] In the field of high-precision gantry machine tools, the traditional ram drive structure is a single screw drive and dual balance cylinder configuration structure, and both ends of the screw are arranged vertically at the upper and lower ends of the slide. Usually, the upper end of the screw is the motor seat, the lower end of the screw is the support seat, and the nut in the middle of the screw is fixed to the ram through the nut seat. This structure is affected by the spatial structure, and the installation space of the screw is relatively compact, which is not convenient for the accuracy of the upper busbar and the side busbar of the screw relative to the reference surface of the slider, so that the assembly accuracy of the screw cannot reach a high level, which not only reduces the transmission accuracy of the screw, but also increases the vibration of the screw.

[0014] The present invention provides a gantry ram double balance and double drive direct push drive structure. It has the following beneficial effects: (1) The lead screw motor of the present invention provides power to drive the movable slide assembly to slide on the slide rail, and the balance hydraulic cylinders on both sides balance the two sides of the movable slide assembly when sliding to prevent lateral deviation. The lead screw calibration assembly at the lower end of the slide rail can eliminate the gap and frame between the threads when switching to reverse drive, and then drive, thereby eliminating the error caused by the servo motor control during movement; (2) The present invention drives the sliding spline shaft to rotate through a screw motor, and can drive the hole sheath screw sleeved outside the sliding spline shaft to rotate, and cooperate with the slide seat screw seat to drive the slide seat frame to move. After moving to the set position, the slide seat fixing cylinder is started to pull the fixing cylinder connecting rod, so that the slide pull rod can slide in the first tightening pull frame and the second tightening pull frame, and pull the slide seat fixing claw to clamp the fixing arranged inside the slide seat track, so as to prevent the slide seat frame from vibrating as a whole; (3) The present invention can control the opening and closing of the cross liquid pipe vertical pipe by starting the second hydraulic driving cylinder to move the second hydraulic sealing slide plug. When the cross liquid pipe is connected, the first hydraulic sealing slide plug at the front end of the first hydraulic driving cylinder pushes the internal liquid, and can push the two vibrating screw components at the upper ends of the two side curved liquid pipes through hydraulic pressure, and push the rotatably installed hole sheath screw at the upper end thereof, so as to eliminate the gap or wear between the screw and the screw thread in the slide seat screw seat; Then, the vibration generating motor is started to drive the vibration generating deflection block to rotate. The rotation axis of the vibration generating deflection block and the output shaft of the vibration generating motor do not coincide, so shaking will occur during rotation. The vibration of the hole sheath screw can prevent it from being tightly pressed against only a few threads in the slide screw seat, and there is still a frame between the other threads. When reverse drive is needed, the second hydraulic sealing plug is moved by starting the second hydraulic drive cylinder to close the cross liquid pipe vertical pipe, and the hydraulic power pushed by the first hydraulic sealing plug can only move to one end of the double-headed connecting sealing plug on one side, and move backward through the other end, so that negative pressure is generated at the upper end of the second hydraulic sealing plug, thereby eliminating the gap and frame amount between the threads during two-way switching before the servo motor is started.

After moving to the set position, the slide fixing cylinder 309 is started to pull the fixed cylinder connecting rod 310, so that the sliding pull rod 316 can slide in the first tightening pull frame 314 and the second tightening pull frame 315, and pull the slide fixing claw 313 to clamp the fixed arrangement inside the slide rail 2, thereby preventing the slide frame 301 from vibrating as a whole.

[0022] like Figure 1 , Figures 7 to 9As shown, the screw calibration component 4 includes: a calibration component base 401, a crossbeam liquid pipe 402, a side bend liquid pipe 403, a vibration recognition assembly 404, a cross liquid pipe 405, a reversing double liquid pipe 406, a first hydraulic drive cylinder 407, a second hydraulic drive cylinder 408, a first hydraulic sealing slide plug 409, and a second hydraulic sealing slide plug 410; the calibration component base 401 is integrally provided with a crossbeam liquid pipe 402, both ends of the crossbeam liquid pipe 402 are integrally provided with side bend liquid pipes 403, and the upper ends of the two side bend liquid pipes 403 are provided with a vibration recognition assembly 404, and the calibration component base 40 A cross liquid pipe 405 is integrated at the lower end; a second hydraulic driving cylinder 408 is fixedly installed at one side end of the cross liquid pipe 405, a first hydraulic driving cylinder 407 is fixedly installed at the lower end of the cross liquid pipe 405, two reversing double liquid pipes 406 are integrated at the other side end of the cross liquid pipe 405, a first hydraulic sealing sliding plug 409 is fixedly installed at the output end of the first hydraulic driving cylinder 407, a second hydraulic sealing sliding plug 410 is fixedly installed at the output end of the second hydraulic driving cylinder 408, and double-head communication sealing sliding plugs 411 are slidably arranged in the two reversing double liquid pipes 406.

[0023] like Figure 7 , Figures 10 to 12 As shown, the vibration recognition button assembly 404 includes: a dust cover seat 4041, a vibration cavity 4042, a motor installation cavity 4043, a seam-eliminating sliding sealing plug 4044, a screw installation rotating seat 4045, a vibration generating motor 4046, a motor power harness 4047, a vibration generating deflection block 4048, and a liquid pipe port dust plug 4049; the upper end of the dust cover seat 4041 is integrated with the vibration cavity 4042, the upper end of the vibration cavity 4042 is integrated with the motor installation cavity 4043, the upper end of the motor installation cavity 4043 is fixedly installed with the screw installation rotating seat 4045, and the dust cover seat 4041 is integrated with the vibration cavity 4042, and the motor installation cavity 4043 is fixedly installed with the screw installation rotating seat 4045. A liquid pipe mouth dust plug 4049 is fixedly installed on the top of the dust cover seat 4041, and a seam-eliminating sliding sealing plug 4044 is fixedly installed on the lower end of the liquid pipe mouth dust plug 4049; a vibration generating motor 4046 is fixedly installed in the motor mounting cavity 4043, and a vibration generating deflection block 4048 is fixedly installed on the output shaft of the vibration generating motor 4046, and the vibration generating deflection block 4048 is arranged in the vibration cavity 4042, and a motor power harness 4047 is connected to the upper end of the vibration generating motor 4046, and the lower end of the hole sheath screw 305 is arranged on the screw mounting rotating seat 4045.

[0024] In the above technical solution, by starting the second hydraulic drive cylinder 408 to move the second hydraulic sealing slide plug 410, the on-off of the vertical pipe of the cross liquid pipe 405 can be controlled. When the cross liquid pipe 405 is connected, the first hydraulic sealing slide plug 409 at the front end of the first hydraulic drive cylinder 407 pushes the internal liquid, and the two vibration recognition screw assemblies 404 at the upper ends of the two side curved liquid pipes 403 can be pushed by hydraulic pressure to push the rotatably installed hole sheath screw 305 at its upper end, and the gap or wear between it and the thread in the slide screw seat 304 is eliminated; Then, the vibration generating motor 4046 is started to drive the vibration generating deflection block 4048 to rotate. The vibration generating deflection block 4048 and the output shaft of the vibration generating motor 4046 do not coincide with each other, so that shaking occurs during rotation. The vibration of the hole sheath screw 305 can prevent it from being pressed against only a few threads in the slide screw seat 304, and there is still a frame between the other threads. When reverse drive is needed, the second hydraulic driving cylinder 408 is started to move the second hydraulic sealing plug 410, so that the vertical pipe of the cross liquid pipe 405 is closed, and the hydraulic power pushed by the first hydraulic sealing plug 409 can only move to one end of the double-headed connecting sealing plug 411 on one side, and move backward through the other end, so that negative pressure is generated at the upper end of the second hydraulic sealing plug 410, thereby eliminating the gap and frame amount between the threads during the two-way switching before the servo motor is started.

[0025] Working principle: The lead screw motor 8 of the present invention provides power to drive the movable slide assembly 3 to slide on the slide rail 2, and the balance hydraulic cylinders 10 on both sides balance the two sides of the movable slide assembly 3 when sliding to prevent lateral deviation, and the lead screw calibration assembly 4 at the lower end of the slide rail 2 can eliminate the gap and frame between the threads when switching to reverse drive, and then drive, thereby eliminating the error generated by the servo motor control during movement; The sliding spline shaft 306 is driven to rotate by the screw motor 8, and the hole sheath screw 305 slidably sleeved outside it can be driven to rotate, and the slide frame 301 can be driven to move in cooperation with the slide screw seat 304. After moving to the set position, the slide fixing cylinder 309 is started to pull the fixed cylinder connecting rod 310, so that the sliding pull rod 316 can slide in the first tightening pull frame 314 and the second tightening pull frame 315, and the slide fixing clamp 313 is pulled to clamp the internal setting of the slide rail 2, so as to prevent the slide frame 301 from vibrating as a whole. Among them, by starting the second hydraulic driving cylinder 408 to move the second hydraulic sealing slide 410, the on-off of the vertical pipe of the cross liquid pipe 405 can be controlled. When the cross liquid pipe 405 is connected, the first hydraulic sealing slide 409 at the front end of the first hydraulic driving cylinder 407 pushes the internal liquid, and the two vibration recognition buckle assemblies 404 at the upper ends of the two side curved liquid pipes 403 can be pushed by hydraulic pressure to push the rotatably installed hole sheath screw 305 at its upper end, and the gap or wear between it and the inner thread of the slide screw seat 304 is eliminated; Then, the vibration generating motor 4046 is started to drive the vibration generating deflection block 4048 to rotate. The vibration generating deflection block 4048 and the output shaft of the vibration generating motor 4046 do not coincide with each other, so that shaking occurs during rotation. The vibration of the hole sheath screw 305 can prevent it from being pressed against only a few threads in the slide screw seat 304, and there is still a frame between the other threads. When reverse drive is needed, the second hydraulic driving cylinder 408 is started to move the second hydraulic sealing plug 410, so that the vertical pipe of the cross liquid pipe 405 is closed, and the hydraulic power pushed by the first hydraulic sealing plug 409 can only move to one end of the double-headed connecting sealing plug 411 on one side, and move backward through the other end, so that negative pressure is generated at the upper end of the second hydraulic sealing plug 410, thereby eliminating the gap and frame amount between the threads during the two-way switching before the servo motor is started.

[0026] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
