[0002] When machining or assembling mechanical components, the mechanical components are usually fixed to the workbench through a locking device to fix the workpiece and increase the operation stability.

It mainly consists of a body seat, a movable jaw, a nut, a screw rod, etc., and plays a role of fixing, clamping, and positioning the workpiece during the machining process. After the existing locking device fixes the mechanical component, it is difficult to adjust the position of the mechanical component according to subsequent work requirements, resulting in a reduction in work efficiency for operators due to discomfort with the fixed position of the mechanical component during the overhaul or assembly process.

The bottom of the turntable assembly is connected to the X-axis moving mechanism. The driving gearbox can drive the turntable assembly to reciprocate along the direction of the X-axis moving mechanism. The handwheel can make the X-axis moving mechanism rotate around the central axis, thereby driving the turntable assembly to rotate synchronously to adjust the direction of the workpiece. The bottom of the Z-axis weighing mechanism is connected to the Y-axis moving mechanism. The Z-axis weighing mechanism reciprocates along the direction of the Y-axis moving mechanism, thereby driving the structures above the Z-axis weighing mechanism to move synchronously.

[0040] In one embodiment, as Figures 1-8As shown in the figure, the present application also provides a universal table locking device, which includes a turntable assembly 7 for locking a workpiece. The bottom of the turntable assembly 7 is connected to an X-axis moving mechanism 1. One end of the X-axis moving mechanism 1 is connected to a driving gearbox 2, and the driving gearbox 2 is used to drive the turntable assembly 7 to reciprocate along the direction of the X-axis moving mechanism 1. The end of the X-axis moving mechanism 1 away from the driving gearbox 2 is connected to a fixed box 3, and one end of the fixed box 3 away from the X-axis moving mechanism 1 is fixedly connected to a handwheel 6. Z-bearing weight mechanisms 4 are respectively arranged at the bottoms of the driving gearbox 2 and the fixed box 3. The bottom of the Z-bearing weight mechanism 4 is connected to a Y-axis moving mechanism 5, and the Z-bearing weight mechanism 4 reciprocates along the direction of the Y-axis moving mechanism 5. Place the mechanical workpiece to be processed on the surface of the turntable assembly 7 and lock and fix it through the turntable assembly 7. The self-rotation of the turntable assembly 7 can adjust the angle of the workpiece. The bottom of the turntable assembly 7 is connected to an X-axis moving mechanism 1. The driving gearbox 2 can drive the turntable assembly 7 to reciprocate along the direction of the X-axis moving mechanism 1. The handwheel 6 can make the X-axis moving mechanism 1 rotate around the central axis, thereby driving the turntable assembly 7 to rotate synchronously to adjust the direction of the workpiece. The bottom of the Z-bearing weight mechanism 4 is connected to a Y-axis moving mechanism 5, and the Z-bearing weight mechanism 4 reciprocates along the direction of the Y-axis moving mechanism 5, thereby driving the structures above the Z-bearing weight mechanism 4 to move synchronously. The X-axis moving mechanism 1 and the Y-axis moving mechanism 5 cooperate to adjust the position of the turntable assembly 7, so as to adjust the working angle and position of the workpiece according to the needs of the operator and improve the working efficiency.

[0041] Referring to Figure 2 , the X-axis moving mechanism 1 includes an X-axis screw 11. One end of the X-axis screw 11 is fixedly connected to the handwheel 6, and the other end extends into the driving gearbox 2. An X-axis slider 13 is sleeved on the outer wall of the X-axis screw 11. Linear slide rods 12 are slidably penetrated through both ends of the X-axis slider 13. The linear slide rods 12 are arranged parallel to the X-axis screw 11, and the X-axis slider 13 reciprocates along the direction of the linear slide rods 12. The top of the X-axis slider 13 is fixedly connected to a fixing plate 10 through a first screw 14. A fixing frame 9 and a first double-headed stud 15 are arranged on the surface of the fixing plate 10. The turntable assembly 7 is rotatably connected to the fixing plate 10 through the first double-headed stud 15, and the turntable assembly 7 is fixed by using a hexagonal thin chamfered nut 22. A turntable screw 8 is installed in the fixing frame 9. The turntable screw 8 meshes with the gear at the bottom of the turntable assembly 7 and forms a transmission ratio of 1:5. When using a wrench to twist the turntable screw 8, the turntable assembly 7 rotates along with the rotation of the turntable screw 8, so as to achieve the purpose of adjusting the angle of the workpiece.

[0042] Referring to Figure 3, the turntable assembly 7 includes a turntable body 19. A turntable bearing 20 is installed at the center of the turntable body 19. Four connecting plates 18 are arranged on the surface of the turntable body 19. One end of each connecting plate 18 is provided with a first nut 17 and a first bolt 21. The connecting plates 18 are fixed to the surface of the turntable body 19 through the first nut 17 and the first bolt 21. A fixing stud 16 is slidably connected inside the connecting plate 18, and the fixing stud 16 is used to fix the workpiece. The turntable bearing 20 can reduce the friction generated when the gear rotates, promoting the smooth rotation of the gear. The first double-headed stud 15 connects the turntable body 19 and the fixing plate 10, and the turntable body 19 is fixed by using a thin hexagon chamfered nut 22, improving the overall stability and connectivity of the X-axis moving mechanism 1. One end of the connecting plate 18 is fixed to the surface of the turntable body 19 through the first nut 17 and the first bolt 21. The fixing stud 16 is slidably arranged inside the connecting plate 18 and can slide with the rotation of the turntable body 19. A variety of regular stud grooves are provided on the turntable body 19. When the workpiece does not match the current stud groove, the position of the fixing stud 16 can be slid to widen the fixing range, improving the adaptability of the locking device.

[0043] Refer to Figure 4 , the drive gearbox 2 includes a box cover 24 and a box body 31. The box cover 24 and the box body 31 are connected by a second screw 23. The box body 31 is fixedly connected to the Y-axis moving mechanism 5 through a second bolt 30. A worm gear and a worm 29 are arranged inside the box body 31. The worm gear and the worm 29 are installed inside the box body 31 through a second bearing 32. One end of the worm 29 is provided with a gland 28, and the gland 28 is installed on the surface of the box body 31. Lubricating oil is contained in the box body 31. A left X-axis connecting seat 25 is arranged on the side surface of the box body 31. The left X-axis connecting seat 25 is fixedly connected to the box body 31 through a mounting pin 26. The lubricating oil keeps the worm gear and the worm 29 in a good lubrication state, reducing wear and improving the transmission smoothness. It can also prevent external impurities from invading and protect the transmission components. The helix angle of the worm 29 is smaller than the equivalent friction angle between the contact surfaces of the worm gear and the worm 29, which can reduce the probability of the worm gear reversing due to gravity or other external forces when the worm 29 is not driven by an external force in the transmission system, having good self-locking property. The axis of the worm gear is arranged at a 90-degree intersection with the axis of the worm 29, and the transmission ratio of the worm gear and the worm 29 is 1:36.

[0044] Refer to Figures 5-8, the fixed box 3 includes a top cover 33 and a base 35. A right X-axis connecting seat 34 is fixed between the top cover 33 and the base 35. The right X-axis connecting seat 34 is used to connect the handwheel 6 and the X-axis screw 11. The base 35 is fixedly connected to the Y-axis moving mechanism 5 through the second bolt 30. The Z-axis bearing mechanism 4 includes a load-bearing column 41 and a screw fixing seat 38. The screw fixing seat 38 is fixedly installed at the bottom of the load-bearing column 41 through the second nut 39 and the second double-headed stud 40. Linear guide rails 36 are penetrated through both ends of the bottom of the load-bearing column 41. A Z-axis rotating screw 37 is installed between the load-bearing column 41 and the screw fixing seat 38. The linear guide rails 36 are arranged in parallel with the Z-axis rotating screw 37. When the Z-axis rotating screw 37 rotates, the load-bearing column 41 reciprocates along the direction of the linear guide rails 36. The two linear guide rails 36 are respectively installed at the lower left corner and the lower right corner of the load-bearing column 41. The Z-axis rotating screw 37 is installed in the screw fixing seat 38 and the load-bearing column 41. The screw fixing seat 38 is fixed to the bottom of the load-bearing column 41 by the second nut 39 and the second double-headed stud 40 respectively. Thus, when the Z-axis rotating screw 37 rotates, the load-bearing column 41 can move back and forth in the linear guide rails 36 at the lower left and lower right. The load-bearing column 41 is processed from precision metal sheets through sheet metal technology, including bending, forming and connecting, constructing a structure that is both strong and light. While making the device have a stable structure and good load-bearing capacity, the self-weight is greatly reduced.

[0045] The Y-axis moving mechanism 5 includes a platform plate 42. The bottom of the load-bearing column 41 passes through the platform plate 42. Both ends of the Z-axis rotating screw 37 are respectively rotationally connected with a column foot sleeve 43 and a Z-axis bearing seat 48. The Z-axis bearing seat 48 is fixedly connected with a guide rail fixing seat 47. One end of the linear guide rail 36 is fixed inside the guide rail fixing seat 47, and the other end of the linear guide rail 36 is fixed to the side wall of the column foot sleeve 43. The column foot sleeve 43 is fixedly installed on the bottom surface of the platform plate 42 through a hexagonal nut 44. The guide rail fixing seat 47 is fixedly installed on the bottom surface of the platform plate 42 through an internal hexagonal stud 49. A bottom shaft 45 is arranged between the two column foot sleeves 43. One end of the bottom shaft 45 passes through the column foot sleeve 43 and is fixedly connected with the handwheel 6. Two bevel gears 46 are arranged inside the column foot sleeve 43. The two bevel gears 46 are respectively fixedly sleeved on the outer walls of the bottom shaft 45 and the Z-axis rotating screw 37 and are fixed by fixing pins to prevent them from moving relative to each other at a predetermined position. The two bevel gears 46 are meshed at a right angle. When the left handwheel 6 is rotated, the bottom shaft 45 drives the bevel gear 46 to rotate accordingly. This rotational power is synchronously transmitted to the Z-axis rotating screw 37 connected to the bevel gear 46, enabling the Z-axis bearing mechanism 4 on the Z-axis rotating screw 37 to move back and forth.

[0046] The implementation principle of a general tabletop locking device in an embodiment of the present application is as follows: Place the mechanical workpiece to be processed on the surface of the turntable assembly 7 and lock and fix it through the turntable assembly 7. The turntable screw 8 meshes with the gear at the bottom of the turntable assembly 7. When using a wrench to turn the turntable screw 8, the turntable assembly 7 rotates along with the rotation of the turntable screw 8 to achieve the purpose of adjusting the angle of the workpiece. The bottom of the turntable assembly 7 is connected to the X-axis moving mechanism 1. The driving gearbox 2 can drive the turntable assembly 7 to reciprocate along the direction of the X-axis moving mechanism 1. The handwheel 6 can make the X-axis moving mechanism 1 rotate around the central axis, thereby driving the turntable assembly 7 to rotate synchronously to adjust the direction of the workpiece. The bottom of the Z-axis weighing mechanism 4 is connected to the Y-axis moving mechanism 5. The Z-axis weighing mechanism 4 reciprocates along the direction of the Y-axis moving mechanism 5, thereby driving the structures above the Z-axis weighing mechanism 4 to move synchronously. The X-axis moving mechanism 1 and the Y-axis moving mechanism 5 cooperate to adjust the position of the turntable assembly 7 to achieve adjusting the working angle and position of the workpiece according to the needs of the operator and improving the working efficiency.

[0047] In one embodiment, as Figures 1-9 shown, a method for adjusting the orientation of a general tabletop locking device provided in an embodiment of the present application specifically includes the following steps:

[0048] S1: Place the workpiece on the surface of the turntable assembly 7 and adjust the angle of the workpiece by rotating the turntable assembly 7;

[0049] S2: Drive the X-axis screw 11 to rotate through the worm gear 27 and worm 29 transmission system of the driving gearbox 2, and drive the X-axis slider 13 to move along the linear slide bar 12;

[0050] S3: Synchronously control the X-axis moving mechanism 1 to rotate around the central axis through the handwheel 6 to achieve the composite direction adjustment of the turntable assembly 7;

[0051] S4: Drive the bottom shaft 45 to rotate through the handwheel 6, and drive the Z-axis rotating screw 37 to rotate through the meshing transmission of the bevel gear 46;

[0052] S5: Utilize the cooperation of the Z-axis rotating screw 37 and the linear guide rail 36 to drive the load-bearing column 41 to reciprocate along the direction of the Y-axis moving mechanism 5;

[0053] S6: Coordinate and control the multi-degree-of-freedom adjustment of the X-axis, Y-axis and turntable assembly 7, and realize the three-dimensional space positioning and locking of the workpiece through the linkage operation of steps S1 - S5.

[0054] In this embodiment, through the systematic operations of steps S1 - S6, the three - dimensional spatial positioning (angle, horizontal, vertical) of the workpiece is achieved, solving the limitation of the traditional locking device being fixed in a single direction. The angle adjustment, X / Y - axis movement, and compound - direction control are integrated into a coherent process, reducing the manual intervention steps, improving the operation efficiency. By means of cooperative control, the synchronization of the adjustment of each axis is ensured, avoiding the cumulative error caused by step - by - step operations and improving the positioning accuracy.

[0055] Preferably, step S1 specifically includes the following steps;

[0056] S11: Place the workpiece on the surface of the turntable assembly 7, and adjust the position of the sliding fixing stud 16 to fit the size of the workpiece;

[0057] S12: Drive the gear at the bottom of the turntable assembly 7 by rotating the turntable screw 8, and control the precise rotation of the turntable assembly 7 with a transmission ratio of 1:5.

[0058] In this embodiment, by adjusting the position of the sliding fixing stud 16, workpieces of different sizes can be adapted, solving the compatibility problem caused by the limitation of the traditional device's fixed slots. Using a 1:5 transmission ratio, the rotation of the turntable screw 8 is precisely converted into the angular change of the turntable assembly 7, improving the adjustment resolution (for example, when the screw rotates 1 circle, the turntable rotates 72°), meeting the requirements of precision machining.

[0059] Preferably, in step S12, the rotation angle of the turntable screw 8 and the rotation angle of the turntable assembly 7 are dynamically matched through a preset transmission ratio, and the transmission ratio is indirectly controlled by the 1:36 transmission ratio between the worm gear 27 and the worm 29 to ensure the self - locking property of the adjustment process.

[0060] In this embodiment, the preset transmission ratio dynamically matches the rotation angle of the turntable assembly 7, avoiding the adjustment deviation caused by mechanical clearance and ensuring the accuracy of angle adjustment. The 1:36 transmission ratio design of the worm gear 27 and the worm 29, combined with the structural characteristic that the spiral angle is less than the equivalent friction angle, automatically locks the position when there is no external force driving, preventing the workpiece from shifting due to vibration or gravity.

[0061] Preferably, in step S3, the rotation of the handwheel 6 is linked with the X - axis screw 11 through the right X - axis connecting seat 34, decomposing the rotational force into the horizontal displacement of the X - axis moving mechanism 1 and the two - way movement of rotation around the axis.

[0062] In this embodiment, by driving the horizontal displacement and the rotation around the axis of the X - axis moving mechanism 1 with a single handwheel 6, the operation complexity is simplified, the adjustment flexibility is improved. The linked design of the right X - axis connecting seat 34 efficiently decomposes the rotational force, reduces the energy loss, and enhances the response speed of the mechanism.

[0063] Preferably, in step S4, the 90-degree meshing transmission of the bevel gear 46 converts the rotational power of the bottom shaft 45 into the axial rotation of the Z-axis rotating screw 37, and restricts the movement path of the load-bearing column 41 through the linear guide 36 to ensure the linear accuracy of the adjustment in the Y-axis direction.

[0064] In this embodiment, the 90-degree meshing of the bevel gear 46 accurately converts the rotational power of the bottom shaft 45 into the axial movement of the Z-axis rotating screw 37, improving the transmission efficiency. The linear guide 36 restricts the movement path of the load-bearing column 41, eliminating the lateral offset in the Y-axis adjustment and ensuring the linearity of the movement trajectory (error ≤ 0.1 mm).

[0065] Preferably, step S6 specifically includes the steps:

[0066] S61: During the X-axis adjustment, the rotation angle of the turntable assembly 7 is fed back in real time, and the displacement of the Y-axis moving mechanism 5 is dynamically adjusted;

[0067] S62: During the Y-axis adjustment, the rotation angle of the X-axis moving mechanism 1 is corrected in reverse according to the displacement of the load-bearing column 41 to compensate for the spatial positioning error.

[0068] In this embodiment, through real-time feedback and dynamic adjustment, a closed-loop control system is formed, significantly reducing the cumulative error in multi-axis collaborative adjustment (for example, the positioning error is reduced by more than 30%). The rotation angle of the X-axis is corrected in reverse according to the displacement of the load-bearing column 41 to automatically compensate for the spatial positioning deviation caused by mechanical deformation or assembly clearance.

[0069] Preferably, after step S6, the following steps are further included:

[0070] S7: A coordinate system is established by the preset position of the stud groove and the sliding trajectory of the fixed stud 16. Combining the displacement parameters of the X-axis, Y-axis, and turntable assembly 7, a three-dimensional adjustment path for the workpiece is automatically generated.

[0071] In this embodiment, a coordinate system is established based on the preset position of the stud groove and the sliding trajectory of the fixed stud 16 to achieve the digital positioning of the workpiece, reducing the manual measurement time. Combining the displacement parameters, a three-dimensional adjustment path is automatically generated to avoid repeated trial and error and improve the adjustment efficiency (for example, the adjustment time for complex workpieces is shortened by 50%).

[0072] In summary, a method for adjusting the orientation of a universal table locking device provided by the present invention includes the following steps: Step S1: Place the workpiece on the surface of the turntable assembly 7, and adjust the angle of the workpiece by rotating the turntable assembly 7; Step S2: Drive the rotation of the X-axis screw 11 through the worm 27 and worm gear 29 transmission system of the drive gearbox 2, and drive the X-axis slider 13 to move along the linear slide bar 12; Step S3: Synchronously control the rotation of the X-axis moving mechanism 1 around the central axis through the handwheel 6 to achieve the composite direction adjustment of the turntable assembly 7; Step S4: Drive the rotation of the bottom shaft 45 through the handwheel 6, and drive the rotation of the Z-axis rotating screw 37 through the meshing transmission of the bevel gear 46; Step S5: Utilize the cooperation between the Z-axis rotating screw 37 and the linear guide rail 36 to drive the load-bearing column 41 to reciprocate along the direction of the Y-axis moving mechanism 5; Step S6: Coordinately control the multi-degree-of-freedom adjustment of the X-axis, Y-axis and turntable assembly 7, and realize the three-dimensional space positioning and locking of the workpiece through the linkage operation of Steps S1-S5. This application has the effect of facilitating the operator to adjust the working angles and positions of mechanical components.
