Description

Technical Field

[0001] The present 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. Both ends of the screw are arranged vertically at the upper and lower ends of the slide. Typically, the upper end of the screw is the motor seat, the lower end is the support seat, and the nut in the middle of the screw is fixed to the ram via the nut seat. This structure is affected by the spatial structure, and the installation space for the screw is relatively compact. This makes it difficult to accurately align the upper and side busbars of the screw with the slider reference surface, making it difficult to achieve a high level of screw assembly accuracy. This not only reduces the transmission accuracy of the screw but also increases the vibration of the screw. While reducing the processing accuracy of the part, it also easily causes chatter marks on the surface of the processed part, reducing the surface finish. Summary of the Invention

[0021] The present invention provides a gantry ram dual-balance and dual-drive direct-push drive structure. It has the following beneficial effects:

[0022] (1) The screw motor of the present invention provides power to drive the movable slide assembly to slide on the slide rail, and the balancing hydraulic cylinders on both sides balance the two sides of the movable slide assembly during sliding to prevent lateral deviation. The 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 is performed, thereby eliminating the error caused by the servo motor control during movement;

[0023] (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 screw seat to drive the slide frame to move. After moving to the set position, the slide fixing cylinder is started to pull the fixed cylinder connecting rod, so that the slide can slide in the first tightening pull frame and the second tightening pull frame by tightening the sliding pull rod, and pull the slide fixing claw to clamp the fixed part set inside the slide track, thereby preventing the slide frame from vibrating as a whole;

[0024] (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. When the cross liquid pipe is connected, the first hydraulic sealing slide at the front end of the first hydraulic driving cylinder pushes the liquid inside, which can push the two vibrating screw assemblies at the upper ends of the two side bend liquid pipes through hydraulic pressure, and push the rotatably installed hole sheath screw at the upper end thereof, thereby eliminating the gap or wear between the screw and the thread inside the slide screw seat;

[0025] Then the vibration motor is started to drive the vibration deflection block to rotate. The rotation axis of the vibration deflection block and the output shaft of the vibration 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 some of the threads in the slide screw seat, and there is still a frame between the other threads.

[0026] When reverse drive is required, the second hydraulic driving cylinder is started to move the second hydraulic sealing slide plug to close the cross liquid pipe vertical pipe, and the hydraulic power pushed by the first hydraulic sealing slide plug can only move to one end of the double-headed connecting sealing slide 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 slide plug, thereby eliminating the gap and frame amount between the threads during two-way switching before the servo motor is started.

The fixed crossbeam 308 is fixedly installed with a slide fixing cylinder 309 on the rear side of the slide fixing crossbeam 308, and the front end of the output end of the slide fixing cylinder 309 is fixedly connected to the fixed cylinder connecting rod 310, and the fixed cylinder connecting rod 310 is integrated with a tightening sliding rod 316, and the front end of the slide fixing cylinder 309 is integrated with two fixed clamping jaw flip frames 311, and the two fixed clamping jaw flip frames 311 are rotatably installed with fixed clamping jaw rotating legs 312 on the upper and lower sides, and a slide fixing clamp 313 is integrated between the two fixed clamping jaw rotating legs 312, and the inner sides of the two slide fixing clamps 313 are integrated with two first tightening pull frames 314 and second tightening pull frames 315, and the tightening sliding pull rod 316 passes through the first tightening pull frame 314 and the second tightening pull frame 315.

[0044] In the above technical solution, the sliding spline shaft 306 is driven to rotate by the screw motor 8, and can drive the hole sheath screw 305 slidingly sleeved outside it to rotate, and cooperate with the slide screw seat 304 to drive the slide frame 301 to move. 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.

[0045] like Figure 1 、 Figures 7 to 9As shown, the screw calibration assembly 4 includes: a calibration assembly 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 409, and a second hydraulic sealing slide 410; the calibration assembly base 401 is integrated with a crossbeam liquid pipe 402, and both ends of the crossbeam liquid pipe 402 are integrated 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 assembly base 40 A cross liquid pipe 405 is integrally provided at the lower end; a second hydraulic drive cylinder 408 is fixedly installed at one end of the cross liquid pipe 405, a first hydraulic drive cylinder 407 is fixedly installed at the lower end of the cross liquid pipe 405, and two reversing double liquid pipes 406 are integrally provided on the other end of the cross liquid pipe 405. A first hydraulic sealing slide 409 is fixedly installed on the output end of the first hydraulic drive cylinder 407, and a second hydraulic sealing slide 410 is fixedly installed on the output end of the second hydraulic drive cylinder 408. Double-head connecting sealing slides 411 are slidably provided in the two reversing double liquid pipes 406.

[0046] 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 mouth 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, the anti- 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 the upper end of the vibration generating motor 4046 is connected to the motor power harness 4047, and the lower end of the hole sheath screw 305 is arranged on the screw mounting rotating seat 4045.

[0047] In the above technical solution, by starting the second hydraulic drive cylinder 408 to move the second hydraulic sealing slide 410, the opening and closing 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 drive cylinder 407 pushes the liquid inside, which can push the two vibrating screw assemblies 404 at the upper ends of the two side curved liquid pipes 403 through hydraulic pressure, and push the rotatably installed hole sheath screw 305 at its upper end, so as to eliminate the gap or wear between it and the thread inside the slide screw seat 304;

[0048] Then, the vibration generating motor 4046 is started to drive the vibration generating deflection block 4048 to rotate. Since the rotation axis of the vibration generating deflection block 4048 and the output shaft of the vibration generating motor 4046 do not coincide, shaking will occur during rotation, and the vibration of the hole sheath screw 305 can prevent it from being tightly pressed against only some of the threads in the slide screw seat 304, while there is still a frame between the other threads.

[0049] When reverse drive is required, the second hydraulic driving cylinder 408 is started to move the second hydraulic sealing slide 410, so that the vertical pipe of the cross liquid pipe 405 is closed, and the hydraulic power pushed by the first hydraulic sealing slide 409 can only move to one end of the double-headed connecting sealing slide 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 slide 410, thereby eliminating the gap and frame amount between the threads during two-way switching before the servo motor is started.

[0050] Working principle:

[0051] The screw motor 8 of the present invention provides power to drive the movable slide assembly 3 to slide on the slide rail 2. The balancing hydraulic cylinders 10 on both sides ensure that the movable slide assembly 3 is balanced on both sides during sliding to prevent lateral deviation. The screw calibration assembly 4 at the lower end of the slide rail 2 can eliminate the gaps and frame amounts between the threads when switching to reverse drive before driving again, thereby eliminating errors caused by servo motor control during movement.

[0052] The sliding spline shaft 306 is driven to rotate by the screw motor 8, and can drive the hole sheath screw 305 slidably sleeved outside it to rotate, and cooperate with the slide screw seat 304 to drive the slide frame 301 to move. 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.

[0053] Among them, by starting the second hydraulic drive cylinder 408 to move the second hydraulic sealing slide 410, the opening and closing 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 drive cylinder 407 pushes the liquid inside, which can push the two vibrating buckle assemblies 404 at the upper ends of the two side curved liquid pipes 403 through hydraulic pressure, and push the rotatably installed hole sheath screw 305 at its upper end, so as to eliminate the gap or wear between it and the thread inside the slide screw seat 304;

[0054] Then, the vibration generating motor 4046 is started to drive the vibration generating deflection block 4048 to rotate. Since the rotation axis of the vibration generating deflection block 4048 and the output shaft of the vibration generating motor 4046 do not coincide, shaking will occur during rotation, and the vibration of the hole sheath screw 305 can prevent it from being tightly pressed against only some of the threads in the slide screw seat 304, while there is still a frame between the other threads.

[0055] When reverse drive is required, the second hydraulic driving cylinder 408 is started to move the second hydraulic sealing slide 410, so that the vertical pipe of the cross liquid pipe 405 is closed, and the hydraulic power pushed by the first hydraulic sealing slide 409 can only move to one end of the double-headed connecting sealing slide 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 slide 410, thereby eliminating the gap and frame amount between the threads during two-way switching before the servo motor is started.

[0056] 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 based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
