However, due to its frequent rotation, a large amount of heat will be generated after long-term use, consuming lubricating oil. In the prior art, the staff regularly adds lubricating oil. This addition method not only affects the lubrication of the bearings but also increases labor costs. Therefore, a high-precision vertical-horizontal conversion mechanism for a machining spindle is provided by those skilled in the art. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0044] Please refer to FIGS. 1-17. A high-precision vertical-horizontal conversion mechanism includes a body 1 and a machining spindle 2 provided on the body 1. One end of the machining spindle 2 is rotatably provided with a fixed machine shaft 21, and an oil box 22 is provided on the fixed machine shaft 21;

[0045] A support disk 12 is provided on the inner wall of the machining spindle 2, an oiling assembly is provided in the fixed machine shaft 21, and one end of the oiling assembly abuts against the support disk 12;

[0046] When the support disk 12 rotates, it drives the oiling assembly to oil intermittently.

[0047] The present invention provides a support plate 12 and an oil box 22, and an oiling component connected to the oil box 22 is provided in the fixed shaft 21. When the support plate 12 rotates following the machining spindle 2, the oiling component can be driven to apply oil. That is, when the machining spindle 2 is running, the rotating connection position between the rotating fixed shaft 21 and the machining spindle 2 can be continuously oiled. That is, the lubrication effect at the connection position can be guaranteed at any time, not only does it not require regular addition, but it can also greatly reduce the unstable rotation and heat caused by lack of lubrication, thereby improving the efficiency of the device as a whole.

[0048] Specifically, in this embodiment, one end of the oiling assembly is intermittently connected to the oil box 22 , and the oiling assembly includes a moving block 1121 , and a ball 112 is rotatably provided on the moving block 1121 , and the ball 112 abuts against the support plate 12 .

[0049] In an embodiment further provided by the present invention, a protrusion 122 is provided on the support plate 12, and when the machining spindle 2 rotates relative to the machine shaft, the protrusion 122 is driven to abut against the ball 112, and the oiling component is driven to intermittently discharge oil.

[0050] In an embodiment further provided by the present invention, a thrust bearing 13 is provided on the machining spindle 2, and the inner wall of the thrust bearing 13 contacts the support plate 12. The present application arranges the thrust bearing 13 and the support plate 12 in correspondence, that is, when the oil is discharged, the lubricating oil can act on the thrust bearing 13 through the oil outlet hole 121 of the support plate 12, that is, the lubricating oil can be continuously supplied.

[0051] In an embodiment further provided by the present invention, the oiling assembly also includes a fixed block 11 fixedly arranged on the inner wall of the fixed main shaft, and a sliding block 111 is slidably arranged in the fixed block 11, and a moving block 1121 is slidably arranged in the sliding block 111, and a first oil pipe 1122 is connected to the moving block 1121, and the first oil pipe 1122 is connected to the groove where the ball 112 is located.

[0052] Furthermore, the oil box 22 is connected to a second oil pipe 221 , and one end of the first oil pipe 1122 is slidably inserted into the second oil pipe 221 , and a sliding pipe 2212 is provided in the second oil pipe 221 , and the sliding pipe 2212 is used to separate the first oil pipe 1122 and the second oil pipe 221 .

[0053] In an embodiment further provided by the present invention, one end of the sliding tube 2212 is provided with an inclined surface, and after the ball 112 is compressed, it drives the moving block 1121 and the connected first oil pipe 1122 to move and squeeze the sliding tube 2212, so that the first oil pipe 1122 and the second oil pipe 221 are connected.

[0054] In a further embodiment provided by the present invention, a cotton wick 2211 is disposed inside the second oil pipe 221, and one end of the cotton wick 2211 abuts against the sliding pipe 2212. After the sliding pipe 2212 is pressed, lubricating oil is extruded. In this embodiment, the cotton wick 2211 has a resilience function. After the cotton wick 2211 is pressed, it can automatically rebound, thereby driving the sliding block 111 to return to the initial position. Moreover, by providing the cotton wick 2211 in this application, it can prevent the oil in the oil box 22 from flowing instantaneously into the first oil pipe 1122, and can cooperate with the sliding pipe 2212 to enable the lubricating oil to flow smoothly into the first oil pipe 1122.

[0055] In a further embodiment provided by the present invention, a rolling groove 1211 is formed on the support disk 12, and a plurality of oil holes 121 are formed in the rolling groove 1211, and the oil holes 121 correspond to the thrust bearing 13;

[0056] And the convex block 122 is disposed in the rolling groove 1211. When the roller rolls, the first oil pipe 1122 can be driven to intake oil through the extrusion of the convex block 122.

[0057] In order to improve the rotational stability between the processing main shaft 2 and the fixed machine shaft 21 in this application, that is, a pressure sensor 23 is disposed on the fixed machine shaft 21, and then a signal rod 231 is slidably connected to the fixed machine shaft 21. One end of the signal rod abuts against the pressure sensor 23, and the other end is slidably connected to an inclined groove formed in the sliding block 111. The direction of the inclined groove is inclined towards the support disk 12. A fourth elastic member 1111 is disposed between the sliding block 111 and the fixed block 11. Under its elastic force, the ball 112 can be made to abut against the rolling groove 1211 formed in the support disk 12. When the processing main shaft 2 and the fixed machine shaft 21 become loose, the support disk 12 connected to the processing main shaft 2 will also move downward, that is, it will no longer stably carry the ball 112. Then, under the elastic force of the fourth elastic member 1111, the sliding block 111 moves towards the support disk 12, that is, the sliding block 111 can drive the signal rod 231 to move towards the pressure sensor 23. Then, the signal rod 231 can be made to press the pressure sensor 23, that is, the sensor 23 can be triggered to move. Then, the sensor 23 is electrically connected to the alarm, that is, a signal can be emitted to make the alarm sound an alarm, so as to quickly and accurately detect the looseness of the processing main shaft 2;

[0058] Moreover, through the mutual cooperation of the support disk 12 and the oiling assembly provided in this application, and by providing the pressure sensor 23 and the signal rod 231, during the operation of the device, it can detect the looseness between the processing main shaft 2 and the fixed machine shaft 21 during the intermittent oiling process, greatly improving the functionality of the device.

[0059] The present invention, through the oiling assembly, the oil box 22 and the support plate 12, can intermittently drive the oil box 22 to supply oil when the machining spindle 2 is running, so as to improve the lubricity of the thrust bearing 13 and the sealing bearing 14. Specifically, when the machining spindle 2 rotates, the support plate 12 fixedly connected thereto is driven to rotate synchronously, and the rotation of the support plate 12 is parallel to the ball 112 and the fixed shaft 21, that is, when the support plate 12 rotates, the ball 112 is constantly fitted in the rolling groove 1211, and then when rotating, the ball 112 passes through the protrusion 122, that is, it can squeeze the roller, so that the ball 112 and the connected moving block 1121 are synchronously moved to The sliding block 111 moves in the direction of the sliding block, that is, it can squeeze the connected first oil pipe 1122 to move in the direction of the sliding tube 2212, and then the sliding tube 2212 can be squeezed, so that the sliding tube 2212 is pressed to move in the direction of the cotton core 2211, that is, the cotton core 2211 is squeezed, so that the lubricant in the cotton core 2211 flows through the pipeline inside the sliding tube 2212 into the connected flow channel 1123, and then flows into the position of the roller through the flow channel 1123, and finally flows into the rolling groove 1211, and then the lubricating oil flows into the outside of the support plate 12 through the oil hole 121 in the rolling groove 1211, and the lubricating oil flows into the thrust bearing 13, thereby improving the lubrication effect.

[0060] In an embodiment further provided by the present invention, a double-station switching mechanism is further provided on the machine body 1, and the double-station switching mechanism includes a first bearing seat 3 and a second bearing seat 5, and the first bearing seat 3 and the second bearing seat 5 are used to support and clamp the workpiece.

[0061] The driving assembly can synchronously drive the first supporting seat 3 and the second supporting seat 5 to switch positions at the same vertical position.

[0062] Specifically, the driving assembly provided in the present invention can drive the first bearing seat 3 and the second bearing seat 5 at the same time, and the core innovation of the present invention lies in that the driving assembly drives the first seat and the second seat to move synchronously, and the movement trajectories are on the same vertical plane, that is, the switching between the two workstations provided in the present application can greatly reduce the space occupied by the device, so that when using a double workstation, it can not only reduce the clamping time of the workpiece, but also reduce the space required for the conversion of the two workstations, thereby improving the rationality of the space occupied by the two workstations.

[0063] Furthermore, the driving component can synchronously drive the first carrier and the second carrier to move. There is a waiting position and a processing position on the machine body 1, and the driving component can drive the first carrier seat 3 and the second carrier seat 5 to switch between the waiting position and the processing position.

[0064] Specifically, the waiting position is the position of the first carrier seat 3 as shown in Figure 1 This position is outside, that is, workpieces can be clamped, while the processing position is inside the machine body 1 and below the processing spindle 2.

[0065] In an embodiment further provided by the present invention, a fixed shaft 41 is fixedly arranged on the machine body 1. The first carrier includes a first carrier rod 32 rotatably arranged on the fixed shaft 41, and the first carrier rod 32 is movably arranged on the first carrier seat 3.

Both the second gear 321 and the third gear 512 are meshed with the first gear 4.

[0068] Furthermore, the second carrier seat 5 is slidably arranged on the machine body 1. When the second carrier seat 5 is driven to move, it drives the two second carrier rods 51 and the third carrier rod 511 to slide relatively.

[0069] In an embodiment further provided by the present invention, fixing columns 63 are fixedly arranged at both ends of the first carrier seat 3. A bearing sleeve 322 is slidably arranged on the first carrier rod 32. After the bearing sleeve 322 is inserted into the fixing column 63, it bears the first carrier seat 3.

[0070] In an embodiment further provided by the present invention, a convex shaft 411 is fixedly arranged on the fixed shaft 41. One end of the bearing sleeve 322 is rotatably provided with a slider 71. The slider 71 is slidably arranged in the first carrier rod 32. An extrusion rod 7 is slidably arranged on the first carrier rod 32. One end of the extrusion rod 7 can abut against the fixed shaft 41, and the other end is slidably arranged in a second extrusion inclined groove 7101 formed on the slider 71.

[0071] In an embodiment further provided by the present invention, an extrusion assembly is also arranged in the second bearing rod 51, and the extrusion assembly includes a first pressure rod 8 slidably arranged on the second bearing rod 51 and a second pressure rod 81 slidably arranged on the first pressure rod 8, and the first pressure rod 8 and the second pressure rod 81 are locked by a locking member.

[0072] In an embodiment further provided by the present invention, the locking member includes an extrusion bevel block 813 slidably disposed on the first pressure rod 8, and a locking buckle 812 is disposed at one end of the extrusion bevel block 813, and the locking buckle 812 can be locked in the locking groove 5112 provided on the second pressure rod 81; one end of the first pressure rod 8 is slidably connected in the limiting sliding groove 4111 provided on the convex shaft 411; and one end of the first pressure rod 8 will not be separated from the limiting sliding groove 4111;

[0073] When the second load rod 51 and the third load rod 511 move relative to each other, the locking buckle 812 is driven to disengage from the locking groove 5112 , and the first pressing rod 8 and the second pressing rod 81 move relative to each other.

[0074] Specifically, the extrusion rod 7 provided in the present application is installed in the same manner as the first pressure rod 8 described above, and one end thereof is slidably connected to a limiting sliding groove 4111 provided on the corresponding convex shaft 411 .

[0075] In an embodiment further provided by the present invention, a limiting column 5111 is provided on the second bearing rod 51, and an extrusion inclined surface 8101 is provided on the extrusion inclined block 813, so that when the second bearing rod 51 and the third bearing rod 511 move relative to each other, the limiting column 5111 can be driven to move toward the extrusion inclined block 813, that is, the extrusion inclined surface 8101 can be extruded, and then the extrusion inclined block 813 can be driven to disengage from the locking groove 5112. That is, the first pressing rod 8 and the second pressing rod 81 can slide relative to each other.

[0076] Furthermore, in order to facilitate the movement of the first bearing seat 3 when it moves to the processing position, the present invention also provides a moving component at the processing position on the machine body 1, which is used to receive the bearing seat moved to the processing position. Then, when it is used, the driving component can be controlled to move to the corresponding position for processing according to actual processing needs, so as to facilitate the processing of the workpiece on the bearing seat;

[0077] Specifically, the moving assembly includes a moving block 9 slidably arranged on the processing position of the machine body 1, and a plug-in block 91 is vertically slidably arranged on the moving block 9, and a third elastic member 911 is arranged between the plug-in block 91 and the moving block 9, and its elastic force can make the plug-in block 91 eject;

[0078] Further, when the carrier base moves to the machining position, the extrusion rod 7 or the first pressing rod 8 inside it abuts against the convex shaft 411 at the corresponding position, that is, it can trigger the carrier sleeve 322 to disengage from the fixed column 63, and then the carrier base disengages from the machining position and is inserted into the bottom of the carrier base to drive its movement.

[0079] Further, to facilitate the disengagement of the carrier base from the moving component after machining, a rotatable partition plate 6 is provided inside the carrier base. The partition plate 6 is rotatably arranged in the insertion slot 301 opened in the carrier base. A pressing block 61 is slidably arranged along the radial direction of the fixed column 63 on the fixed column 63. A first elastic member 611 is arranged between the pressing block 61 and the fixed column 63. An abutting rod 62 is slidably arranged on the first carrier base 3. One end of the abutting rod 62 passes through the first carrier base 3 and is inserted into the locking groove opened on the partition plate 6. When the pressing block 61 is pressed to move into the fixed column 63, it can press the abutting rod 62, so that the insertion block 621 arranged at one end of the extrusion rod 7 can disengage from the locking groove opened on the partition plate 6, that is, the partition plate 6 can be rotated.

[0080] Further, a support block 3221 is fixedly arranged at one end of the carrier sleeve 322. Under its own gravity, the support block 3221 is always in a hanging state. After machining is completed, the moving component moves to the position corresponding to the support block 3221, that is, it can press the partition plate 6 through the support block 3221, and then press the partition plate 6, so that the insertion block 621 arranged at one end of the extrusion rod 7 can disengage from the locking groove opened on the partition plate 6, that is, the partition plate 6 can be rotated, and then it is convenient for the carrier base to disengage from the insertion block 91.

[0081] In the present invention, a convex shaft 411 is provided on a fixed shaft 41, and then corresponding extrusion rods 7 are provided in a first bearing rod 32 and a second bearing rod 51 to act on the convex shaft 411. When the first bearing rod 32 moves to a position where it abuts against the convex shaft 411, it can drive the extrusion bearing sleeve 322 to disengage from the fixed column 63. That is, the bearing sleeve 322 can be disengaged from the fixed column 63, causing the first bearing rod 32 to disengage from the support of the fixed column 63. That is, the first bearing rod 32 is disengaged from the first bearing seat 3. Then, the first bearing seat 3 can be passively arranged on the moving block 9. That is, the bearing seat can be arranged on the moving component, and then the position of the moving component can be adjusted according to the applied processing position, so as to adapt to the processing of the processing spindle 2. That is, through the arranged moving component and the detachable first bearing seat 3 in the present application, while reducing the use space, the first bearing rod 32 can be disengaged from the first bearing seat 3. That is, the first bearing seat 3 for clamping the workpiece to be processed can be passively inserted onto the moving component, realizing the function of moving the workpiece during processing. Moreover, throughout the process, the insertion and disengagement of the corresponding bearing seat and the insertion block 91 can be achieved through the movement of the first bearing member and the second bearing member, improving the linkage and functionality of the device as a whole.

[0082] When the present invention is in use, for the convenience of description, the following description of the "carrier seat" refers to both the first carrier seat 3 and the second carrier seat 5. When the present invention is in use, the working principle of the present invention is introduced in detail with the second carrier seat 5 moving from the waiting position to the processing position. First, the motor for driving the movement of the first gear 4 is driven, and then the two meshing second gears 321 and third gears 512 are driven to move in opposite directions, that is, the second carrier rod 51 is driven to move from the waiting position towards the processing position. During the movement, the second carrier rod 51 is driven to move synchronously, and at this time, the first carrier seat 3 rotates along the axis of the first carrier rod 32. And the second carrier seat 5 slides along the sliding direction provided on the machine body 1. Then, during the movement process, a relative telescopic sliding occurs between the second carrier rod 51 and the third carrier rod 511, so as to adapt to the sliding of the second carrier seat 5. Before the second carrier rod 51 moves to the processing position, the second carrier rod 51 and the third carrier rod 511 are gradually driven to be relatively elongated, that is, the internal first pressure rod 8 and the second pressure rod 81 are gradually stretched to the longest position, that is, the locking block provided on the pressing block 813 is gradually squeezed and contracted and then inserted into the locking groove 5112, that is, at this time, their relative fixation is maintained. Then, when continuously rotating, one end of the first pressure rod 8 abuts against the convex shaft 411, and then the first pressure rod 8 and the second pressure rod 81 are gradually squeezed. Finally, the slider 71 connected to one end of the second pressure rod 81 is pressed, that is, the shaft provided on the second pressure rod 81 gradually presses the slider 71, and the slider 71 is gradually moved into the third receiving rod, driving the connected bearing sleeve 322 to gradually disengage from the fixed column 63 and finally completely disengage. And during this process, the first carrier seat 3 gradually moves to the processing position. Then, the partition plate 6 presses the plug-in block 91, and finally the plug-in block 91 is finally inserted into the plug-in groove 301. Then, the moving component can perform adaptive movement according to the processing needs. A driving device is provided below the moving component, which can drive the moving block 9 to move, that is, it can perform adaptive movement. After the processing is completed, the moving component moves to the processing position, that is, the position where the second carrier seat 5 is located when the bearing sleeve 322 just disengages from the fixed column 63. During the movement of the moving component, the pressing blocks 61 provided on both sides of it will move to the support block 3221 provided on the second gear 321. Then, under the extrusion of the support block 3221, the pressing block 61 will be extruded into the fixed column 63, and finally the plug 621 is driven to disengage from the partition plate 6. Then, the partition plate 6 can rotate, and then the partition plate 6 can be rotated along as Figure 6Rotate in the direction of the arrow shown, that is, it will not prevent the first carrier 3 from disengaging from the plug block 91. Then, the drive motor that drives the first gear 4 to rotate reverses, that is, drives the second carrier rod 51 and the third carrier rod 511 to rotate. When the second carrier rod 51 and the third carrier rod 511 move relative to each other, it can drive the limit post 5111 to move in the direction of the pressing inclined block 813, that is, it can press the pressing inclined surface 8101, and then drive the pressing inclined block 813 to disengage from the locking groove 5112. Then, the second carrier 5 can be driven to slide, and at this time, the second carrier rod 51 and the third carrier rod 511 slide and contract, and finally, the positions of the first carrier 3 and the second carrier 5 are switched, and then the processing of the next workpiece can be carried out.
