Description

Technical Field

[0001] The invention relates to a supporting mechanism, in particular to an operating table supporting mechanism capable of realizing four-dimensional adjustment. Background Art

[0002] A high-end horizontal turning-milling machining center is a complex machine tool with multiple functional components centrally installed within the same machine. Each component has complex functions and movements, and all components are controlled centrally on the console, including CNC programming, setting machine parameters, and setting tool parameters. Therefore, operators often need to operate the console for a long time. Traditional consoles are fixed and cannot be adaptively adjusted to the operator's height, ambient light conditions, and other factors. Operators are very prone to fatigue after prolonged operation, which can lead to low work efficiency and even operational errors.

[0003] To address the above issues, some manufacturers now provide an adjustable support mechanism for the operating table of the horizontal turning and milling compound machining center. However, the existing support mechanism has relatively few degrees of adjustment freedom, generally two-dimensional, and a few three-dimensional, but it still cannot meet the actual needs of multi-directional adjustment.

[0004] Therefore, a method or device that can solve the above problems is needed. Summary of the Invention

This allows the user to operate the operating table in the most comfortable and convenient manner, improving the user's operational experience and preventing fatigue during prolonged operation, thereby avoiding operational errors due to lack of concentration. Furthermore, this support structure boasts a simple manufacturing process and low manufacturing cost, offering numerous advantages, making it particularly suitable for promotion and application in this field, and possessing a promising market prospect.

DETAILED DESCRIPTION

[0025] The specific embodiments of the present invention will be described below with reference to the accompanying drawings: Figures 1 to 7 As shown, a four-dimensionally adjustable operating table support mechanism includes a horizontal guide rail 2 fixedly connected to a machining center frame 1, a guide rail block 3 slidably connected to the horizontal guide rail 2, and a guide rail block 3 is fixedly connected to the bottom end of a guide slide 4. The top of the guide slide 4 is provided with a pair of symmetrically distributed upper guide wheels 5, and the rotating shafts of the upper guide wheels 5 are longitudinally distributed. The two upper guide wheels 5 are clamped on both sides of a guide wheel bracket 6 fixedly connected to the machining center frame 1, and the guide slide 4 is provided with a support column 7 placed in the horizontal direction.

[0026] The end of the support column 7 is provided with a bottom platform 8, and the top of the bottom platform 8 is provided with a lifting cylinder. The lifting cylinder includes a lower cylinder 9 whose bottom end surface is fixedly connected to the bottom platform 8, and an upper cylinder 10 is movably sleeved outside the lower cylinder 9. A balancing cylinder 11 and a spiral guide tube 12 are also provided in the lifting cylinder. The bottom end of the balancing cylinder 11 is connected to the lower cylinder 9, and the top end is connected to the upper cylinder 10, and the spiral guide tube 12 is located on the outside of the balancing cylinder 11. A rotating shell 13 is rotatably connected to the top surface of the upper cylinder 10, and a rotary locking mechanism is provided on the outer wall of the rotating shell 13.

[0027] A cable inlet 14 is provided on the bottom end surface of the rotating shell 13, and a cable outlet 15 is provided on the top end surface. The cable inlet 14 corresponds to the arc groove provided on the top end surface of the upper cylinder 10. The cable inlet 14 and the cable outlet 15 are respectively located at the two ends of a certain diameter on the rotating shell 13. A lifting control knob 16 is threadedly connected to the side wall of the rotating shell 13. The end of the lifting control knob 16 is provided with an eccentric wheel 17 located inside the rotating shell 13. The trigger shaft 18 at the top end of the balancing cylinder 11 is located below the eccentric wheel 17 and can be triggered by the eccentric wheel 17. A spring 19 is also provided at the bottom of the trigger shaft 18.

[0028] A hinge seat 20 is provided on the top surface of the rotating shell 13. The hinge seat 20 is rotatably connected to the operating table 21 through a rotating shaft. A locking hand wheel 22 matching the rotating shaft is also provided on the hinge seat 20.

[0029] The operating table 21 is connected to a cable. The cable enters the spiral guide tube 12 through a through hole at the bottom of the lower cylinder 9 and exits from the opening at the top of the spiral guide tube 12. Then, the cable enters the inner cavity of the rotating shell 13 through the cable inlet 14 and finally exits through the cable outlet 15 and is connected to the operating table 21.

[0030] The rotary locking mechanism includes a top screw 23 threadedly connected to the side wall of the rotating shell 13, one end of the top screw 23 located outside the rotating shell 13 is connected to a handle 24, and the other end of the top screw 23 is located inside the rotating shell 13. A locking block 25 in contact with the top screw 23 is also provided in the rotating shell 13. A locking column 26 is provided on the top surface of the upper cylinder 10 and is sleeved on the outside of the trigger shaft 18. One end of the locking block 25 can contact the surface of the locking column 26.

[0031] A pre-stressed disc spring 27 is sleeved on the end of the locking hand wheel 22 .

[0032] A cable fixing hoop 28 is provided at the top opening of the upper cylinder 10 .

[0033] The hinge seat 20 is a hollow structure. The cable passes through a long notch 29 at the bottom of the hinge seat 20 and is connected to the operating table 21. A notch insert 30 is also provided at the long notch 29.

[0034] The working process of the operating table support mechanism capable of four-dimensional adjustment in an embodiment of the present invention is as follows: when the operating table 21 needs to be moved horizontally, it is only necessary to manually push the bottom platform 8 or the lifting cylinder to allow the guide slide 4 to move linearly in the horizontal direction along the horizontal guide rail 2, and stop pushing after the operating table 21 moves to the appropriate position.

[0035] When the height of the operating platform 21 needs to be changed, the operator first rotates the lifting control knob 16. When the lifting control knob 16 is rotated, the eccentric wheel 17 is driven to move, and the eccentric wheel 17 presses down the trigger shaft 18, and the balancing cylinder 11 is unlocked. The operator can lift or press down the operating platform 21. Under the action of the balancing cylinder 11, the operator can easily adjust the position of the operating platform 21 in the Z-axis direction. During the lifting process, the lower cylinder 9 does not move, and the upper cylinder 10 sleeved on its outer side will perform a lifting action relative to the lower cylinder 9 (that is, the lifting cylinder is stretched or shortened as a whole) to adjust the height of the operating platform 21. After adjusting to the appropriate height, the lifting control knob 16 is rotated in the opposite direction, and the eccentric wheel 17 rotates in the opposite direction. After the pressure of the eccentric wheel 17 is lost, under the action of the spring 19, the trigger shaft 18 returns to the initial position. At this time, the balancing cylinder 11 returns to the locked state again, and the height of the operating platform 21 is positioned.

[0036] When the operating platform 21 needs to be driven to rotate on a horizontal plane, the operator first opens the rotation locking mechanism to release the lock between the rotating shell 13 and the upper cylinder 10. Then, the operator holds the operating platform 21 and drives the rotating shell 13 to rotate relative to the upper cylinder 10. After rotating to a suitable angle, the operator re-engages the rotation locking mechanism to lock the rotating shell 13 and the upper cylinder 10.

[0037] The working process of the above-mentioned rotary locking mechanism is as follows: the top screw 23 is driven to rotate by the handle 24. Since the top screw 23 is threadedly connected to the rotating shell 13, it will also move along its own axial direction while rotating, pushing the locking block 25 to move horizontally in the rotating shell 13. The end face of the locking block 25 presses on the outer surface of the locking column 26 and applies a certain pressure. Since the locking column 26 is a part of the upper cylinder 10 and the locking block 25 is located in the rotating shell 13, the friction between the locking block 25 and the locking column 26 will lock the upper cylinder 10 and the rotating shell 13; when the lock between the two needs to be released, the top screw 23 is rotated in the opposite direction, and the top screw 23 moves in the opposite direction, and no pressure is applied to the locking block 25. At this time, there is only a contact relationship between the locking block 25 and the locking column 26 but no friction, so the rotating shell 13 can rotate freely relative to the upper cylinder 10.

[0038] When the pitch angle of the operating table 21 needs to be adjusted, the operator rotates the locking handwheel 22, and the locking handwheel 22 releases the lock on the rotating shaft. The operator holds the operating table 21 and applies force to change its pitch angle. When the angle is appropriate, the locking handwheel 22 is tightened again to fix the operating table 21 at the current angle; since a pre-stressed disc spring 27 is provided at the end of the locking handwheel 22, even when the locking handwheel 22 is in the unlocked state, the pre-stressed disc spring 27 will apply a certain pressure to the rotating shaft, which can prevent the operating table 23 from rotating rapidly due to excessive weight and causing it to collide with other mechanisms.

[0039] Since the rotating shell 13 can rotate relative to the upper cylinder 10, the various cables connected between the two may be twisted or even tangled during their relative rotation. To prevent the above problem, the cable inlet 14 of the rotating shell 3 is opened on its bottom end surface, and the cable outlet 15 is opened on its top end surface, and the cable inlet 14 and the cable outlet 15 are located on opposite sides (that is, the cable inlet 14 and the cable outlet 15 are respectively located at the two ends of a certain diameter on the rotating shell 13). After the cable enters the inner cavity of the rotating shell 13 through the cable inlet 14, it is routed horizontally and then passes upward through the cable outlet 15. In this way, when the rotating shell 13 rotates, the horizontal section of the cable located inside the rotating shell 13 also rotates. In other words, the cables are not fixed relative to the rotating shell 13, so the cables will not be entangled or tangled.

[0040] When the rotating shell 13 rotates relative to the upper cylinder 10, the arc groove formed on the top surface of the upper cylinder 10 can prevent the cable from being caught between the rotating shell 13 and the upper cylinder 10, thereby ensuring that the cable will not be damaged by shear force.

[0041] The entire device is mounted on the machining center frame 1 via a guide slide 4. Two points below and one point above the guide slide 4 form a three-point rolling support structure, achieving a structural design with the thinnest guide slide 4, the smallest guide span, and the least number of load-bearing blocks. This ensures that the sliding support components of the overall operating table 21 are highly integrated with other components in an extremely narrow space and achieve smooth sliding. The upper guide wheel 5 located above is fine-tuned by the guide wheel bracket 6 to achieve the required equidistant degree from the two guide rail blocks 3 at the lower end.

[0042] The cables required to connect to the operating table 21 are led out from the spiral guide tube 12 and enter the rotating shell 13 through the opening at the top of the upper cylinder 10. A cable fixing hoop 28 is also provided at the opening at the top of the upper cylinder 10. The cable fixing hoop 28 can ensure that the cables do not slide during operation and prevent cable wear.

[0043] Since the front end of the cable generally has a large connector, a long notch 29 is provided at the bottom end of the hinge seat 20 to allow the connector to pass smoothly. After the connector is connected to the operating table 21, the notch insert 30 is reinserted into the long notch 29, so that the entrance part of the hinge seat 20 can be re-formed into a smooth round hole. In this way, when the operating table 21 makes a pitching movement, the cable can be protected from wear.
