Description

Technical Field

[0001] The present invention relates to the technical field of tool presetters, and more specifically, to a spindle rotation device for a tool presetter. Background Art

[0002] A tool presetter is a precision instrument used for pre-adjusting and measuring tools. It is mainly used to accurately measure and adjust parameters such as the length, diameter, and tool angle of the tool before machine tool processing to ensure the accuracy and stability of the tool during the processing, improve the processing quality and efficiency. In the processing of key components such as automotive engines and transmissions, a large number of high-precision tools are required. The tool presetter can ensure the accuracy of the tool, guarantee the processing quality and assembly accuracy of automotive parts, and improve the performance and reliability of the vehicle.

[0003] The spindle rotation device of the tool presetter is a key component in the tool presetter, mainly used to achieve purposes such as multi-angle measurement, simulating the processing state, improving the measurement accuracy, and detecting the dynamic balance of the tool.

[0004] In the current prior art, in order to ensure better stability and accuracy when the spindle rotates, it is usually necessary to regularly add a certain amount of lubricant to its interior during use, thereby reducing the friction and heat generated when the spindle rotates. During production operations, to ensure the stability of the spindle, it is necessary to frequently replenish the lubricant. When the existing lubricant is replenished, it is usually directly introduced, which is very easy to apply too much and extremely likely to cause unnecessary waste.

[0005] Therefore, the present invention provides a spindle rotation device for a tool presetter. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A spindle rotation device for a tool presetter according to the present invention includes a rod base. A flange plate is fixedly installed at the bottom of the rod base. A motor is arranged inside the rod base. The output end of the motor is fixedly installed with a spindle. A tool presetter is arranged at the top of the spindle. A plurality of tool placement grooves are formed inside the tool presetter. A sliding disk is fixedly installed at the top of the rod base. The outer wall of the spindle passes through the inner wall of the sliding disk and is rotatably connected to the inner wall of the sliding disk. A storage tank and a dosing tank are fixedly installed outside the sliding disk. The storage tank is arranged directly above the dosing tank. A replenishment assembly is arranged between the storage tank and the dosing tank. The replenishment assembly includes a absorbent cotton rod. The replenishment assembly is used to flow the lubricant placed in the dosing tank back to the storage tank through the absorbent cotton rod. A refueling assembly is arranged outside the storage tank. The refueling assembly is used to replenish the lubricant into the sliding disk;

[0008] First, fix the flange to the designated position using bolts and nuts. Then, insert the tool presetting instrument into the top of the spindle. When both are installed, a complete rotating device is formed. When tool switching is required, control the motor to rotate through the system. The motor drives the tool presetting instrument to rotate through the spindle, so that the tool placed in the tool presetting instrument can be switched in position. When the spindle rotates, the reservoir supplies lubricant to the sliding plate through the oil replenishing component to ensure the activity of the lubricant in the sliding plate and prevent the instability and inaccuracy of the spindle rotation caused by insufficient or dry lubricant in the sliding plate. At the same time, a part of the lubricant in the sliding plate flows back into the reservoir. Finally, the replenishing component passes the lubricant in the reservoir back to the reservoir through the absorbent cotton rod to replenish the outflowing lubricant, reduce the waste of lubricant, save resources, avoid the one-time consumption of lubricant, and ensure its activity at the same time, making it recyclable and more conducive to lubricating the sliding plate.

[0009] Preferably, a balance disk is fixedly installed on the outer wall of the spindle. A plurality of rotating shafts are fixedly installed on the inner wall of the balance disk. A plurality of sleeve caps are fixedly installed at the bottom of the tool presetting instrument. The tops of the plurality of rotating shafts are respectively slidably connected to the inside of the plurality of sleeve caps. During installation, insert the plurality of rotating shafts into the sleeve caps at the bottom of the tool presetting instrument, and then insert the bottom of the tool presetting instrument into the top of the spindle. When the tool presetting instrument needs to be rotated to switch tools, when the spindle rotates, the balance disk and the plurality of rotating shafts drive the tool presetting instrument to rotate, which can improve the stability of the tool presetting instrument during rotation and is more conducive to the tool presetting instrument rotating to switch tools, preventing the tool presetting instrument from shaking or wobbling when the spindle drives the tool presetting instrument to rotate because it rotates around a fulcrum.

[0010] Preferably, a connecting shaft is fixedly installed at the bottom of the tool presetting instrument. The connecting shaft is a cylinder. A plurality of retaining blocks are slidably connected to the inner wall of the spindle. A plurality of retaining springs are arranged between one side of each of the plurality of retaining blocks and the inner wall of the spindle. The outer wall of the connecting shaft is slidably connected to the outer walls of the plurality of retaining blocks. The outer walls of the plurality of retaining blocks are all inclined sliding surfaces. When the tool presetting instrument is inserted into the spindle, by pressing down the tool presetting instrument, the connecting shaft at the bottom of the tool presetting instrument pushes the plurality of retaining blocks to move to both sides in the spindle. When the connecting shaft at the bottom of the tool presetting instrument completely enters the spindle, the plurality of retaining blocks fix the connecting shaft at the bottom of the tool presetting instrument through the elastic force of the retaining springs, thus realizing the installation of the tool presetting instrument and the spindle, playing a role in facilitating installation. The tool presetting instrument is fixed by moving the plurality of sleeve caps, enabling the spindle to be installed with a variety of tool presetting instruments of different sizes.

[0011] Preferably, a plurality of fluid pipes are fixedly installed at the bottom of the agent storage tank. An annular ball groove is formed in the inner wall of the sliding disk. One end of each of the plurality of fluid pipes is fixedly installed inside the annular ball groove. Through openings are symmetrically arranged at the top of the agent storage tank. When the tool presetting instrument rotates, the lubricant in the agent storage tank will flow into the annular ball groove in the sliding disk through the fluid pipes, so as to supplement the lubricant in the annular ball groove, prevent the lubricant in the annular ball groove from being too little or having low activity, which affects the rotation of the tool presetting instrument, and play a role in supplementing the lubricant.

[0012] Preferably, the bottom ends of a plurality of rotating shafts are rotatably connected with ball blocks. The outer walls of the plurality of ball blocks are slidably connected with the inner wall of the annular ball groove. When the motor drives the tool presetting instrument to rotate through the rotating shafts and the main shaft, the ball blocks at the bottom ends of the rotating shafts slide on the inner wall of the annular ball groove. Due to the spherical setting of the ball blocks, the friction area between the rotating shafts and the sliding disk can be reduced, which is beneficial to the rotation of the rotating shafts in the annular ball groove, and ensures the stability of the tool presetting instrument. When the rotating shafts move in the annular ball groove, the moving ball blocks can also rotate automatically inside the annular ball groove, so that the lubricant introduced through the fluid pipes can be applied to the whole body of the ball blocks, preventing the friction of the whole body of the ball blocks from increasing due to the lack of lubricant application, which affects the stability of the rotating shafts during rotation, and indirectly affects the rotation of the tool presetting instrument.

[0013] Preferably, the oil replenishing assembly includes plugging rods. The number of the plugging rods is the same as that of the fluid pipes. The outer walls of the plurality of plugging rods are slidably connected with the inner walls of the plurality of fluid pipes respectively. Convex blocks are fixedly installed at the top ends of the plurality of plugging rods. Extrusion blocks are fixedly installed on the outer walls of the plurality of rotating shafts. The bottoms of the plurality of extrusion blocks can all slide on the tops of the plurality of convex blocks. The bottoms of the plurality of extrusion blocks and the tops of the plurality of convex blocks are both inclined sliding surfaces. When the rotating shafts rotate, the rotating shafts drive the extrusion blocks to rotate. When the extrusion blocks rotate and contact the convex blocks, the extrusion blocks extrude the convex blocks to move downward, so that the convex blocks drive the plugging rods to move downward and open inside the fluid pipes. Then the lubricant placed in the agent storage tank will flow into the annular ball groove along the pipe wall of the fluid pipes and the openings on the plugging rods to supplement the lubricant. By controlling the replenishment of the lubricant through the rotation of the rotating shafts, the flow rate of the lubricant entering the annular ball groove can be controlled, avoiding waste of resources caused by excessive lubricant introduction, and playing a role in controlling the flow rate of the lubricant introduction.

[0014] Preferably, a plurality of hollow shafts are fixedly installed at the top of the agent placement tank. The outer walls of the plurality of plugging rods are slidably connected with the inner walls of the plurality of hollow shafts respectively. A return spring is arranged between the bottom ends of the plurality of plugging rods and the inner walls of the plurality of hollow shafts. When the extrusion blocks and the convex blocks are out of contact, the plugging rods will be elastically rebounded and reset by the return spring, and the plugging rods will close the fluid pipes to prevent the lubricant in the fluid pipes from flowing out, playing a role in resetting the plugging rods to block the outflow of the lubricant.

[0015] Preferably, a plurality of return agent pipes are fixedly installed at the bottom end of the sliding disk. One ends of the plurality of return agent pipes penetrate through the inner wall of the rod seat and are placed inside the agent placing box. A poly-agent ring block is fixedly installed inside the agent placing box. When the ball block finishes rotating in the annular ball groove, the ball block will stop rotating, and the lubricant placed in the annular ball groove will flow back into the agent placing box along the return agent pipe and finally be placed between the poly-agent ring blocks for storage, playing a role in recycling the lubricant.

[0016] Preferably, the replenishing assembly further includes hollow rods. The number of the hollow rods and the absorbent cotton rods is multiple. The multiple absorbent cotton rods are respectively placed inside the multiple hollow rods. The top ends of the multiple absorbent cotton rods are rotatably connected to the inner wall of the agent placing box, and the bottom ends of the multiple absorbent cotton rods are placed at the inner grooves of the poly-agent ring blocks. When the lubricant enters the poly-agent ring blocks, since the absorbent cotton rods are made of fibrous cotton, when the bottom ends of the absorbent cotton rods come into contact with the lubricant placed in the poly-agent ring blocks, capillary action will occur on the absorbent cotton rods, so that the lubricant will adsorb and move upward at the bottom of the absorbent cotton rods. The lubricant recovered into the agent placing box will move into the storage agent box for lubricant replenishment, playing a role in replenishing the lubricant. By using fibrous cotton rods as the absorbent cotton rods, the lubricant can also be filtered to prevent impurities from being mixed in the returned lubricant, affecting subsequent use.

[0017] Preferably, push rods are fixedly installed on the outer walls of the multiple rotating shafts. One ends of the multiple push rods are rotatably connected to pressing cotton shafts. Arc-shaped panels are fixedly installed at the tops of the multiple hollow rods. The inner wall of the agent placing box is rotatably connected with multiple groups of shaft blocks. The number of each group of shaft blocks is three, and the three shaft blocks are symmetrically arranged in a triangular shape outside the absorbent cotton rods. The outer walls of the multiple pressing cotton shafts can respectively slide on the outer walls of the multiple absorbent cotton rods. When the lubricant flows upward to the top ends of the absorbent cotton rods through capillary action, since the absorbent cotton rods adsorb the lubricant, the absorbent cotton rods will expand. Therefore, when the lubricant is placed at the top ends of the absorbent cotton rods, when the rotating shaft moves next time, the rotating shaft drives the push rod to rotate. When the push rod rotates, the push rod squeezes and pushes the top end of the absorbent cotton rod to rotate. When the push rod touches the top end of the absorbent cotton rod, through the extrusion and pushing cooperation of the pressing cotton shaft and the external restriction of the three shaft blocks, the lubricant placed at the top end of the absorbent cotton rod will be extruded out of the inside of the absorbent cotton rod and drip onto the arc-shaped panel around the smooth shaft block and finally fall into the storage agent box for storage, playing a role in extracting the lubricant.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A spindle rotation device of a tool presetting instrument according to the present invention. When the lubricant flows upward to the top of the absorbent cotton rod by capillary action, the absorbent cotton rod expands. When the rotating shaft moves next time, the rotating shaft drives the push rod to rotate. The push rod squeezes and pushes the top of the absorbent cotton rod to rotate. When the push rod contacts the top of the absorbent cotton rod, it is squeezed and pushed by the cotton pressing shaft in cooperation with the external restriction of the three shaft blocks. The lubricant placed at the top of the absorbent cotton rod will be squeezed out of the inside of the absorbent cotton rod, dripped onto the arc-shaped panel around the smooth shaft block, and finally fall into the inside of the storage agent box for storage, playing the role of extracting the lubricant.

[0020] 2. A spindle rotation device of a tool presetting instrument according to the present invention. When the bottom end of the absorbent cotton rod contacts the lubricant placed in the agent collecting ring block, capillary action will occur on the absorbent cotton rod, so that the lubricant adsorbs and moves upward from the bottom of the absorbent cotton rod. The lubricant recovered into the agent storage box will move into the storage agent box for lubricant replenishment, playing the role of replenishing the lubricant. Since the absorbent cotton rod is made of fibrous cotton, it can also filter the lubricant to prevent impurities from being mixed in the recycled lubricant, affecting subsequent use.

[0021] 3. A spindle rotation device of a tool presetting instrument according to the present invention. The rotating shaft drives the extrusion block to rotate. When the extrusion block rotates and contacts the convex block, the extrusion block squeezes the convex block to move downward, so that the convex block drives the plugging rod to move downward and open in the flow agent pipe. The lubricant placed in the storage agent box will flow into the annular ball groove along the inner wall of the flow agent pipe and the opening on the plugging rod for lubricant replenishment. By controlling the lubricant replenishment through the rotation of the rotating shaft, the flow rate of the lubricant entering the annular ball groove can be controlled, avoiding waste of resources caused by excessive lubricant being introduced, playing the role of controlling the flow rate of the lubricant introduced.

[0022] 4. A spindle rotation device of a tool presetting instrument according to the present invention. When the motor drives the tool presetting instrument to rotate through the rotating shaft and the spindle, the ball block at the bottom end of the rotating shaft slides on the inner wall of the annular ball groove. Due to the spherical setting of the ball block, the friction area between the rotating shaft and the sliding disk can be reduced, which is beneficial to the rotation of the rotating shaft in the annular ball groove and ensures the stability of the tool presetting instrument. When the rotating shaft moves in the annular ball groove, the moving ball block can also rotate automatically inside the annular ball groove, so that the lubricant introduced from the flow agent pipe can be applied to the whole body of the ball block, preventing the friction from increasing due to the lack of lubricant application on the whole body of the ball block, affecting the stability of the rotating shaft during rotation, and indirectly affecting the rotation of the tool presetting instrument.

[0023] 5. A spindle rotation device of a tool presetting instrument according to the present invention. When the tool presetting instrument is inserted into the spindle, by pressing down the tool presetting instrument, the connecting shaft at the bottom of the tool presetting instrument pushes a plurality of retaining blocks to move to both sides in the spindle. When the connecting shaft at the bottom of the tool presetting instrument completely enters the spindle, the plurality of retaining blocks fix the connecting shaft at the bottom of the tool presetting instrument by the elastic force of the retaining spring, thereby realizing the installation of the tool presetting instrument and the spindle, playing a role of facilitating installation. By moving a plurality of sleeve caps to fix the tool presetting instrument, the spindle can be installed with a variety of tool presetting instruments of different sizes.

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0037] As Figures 1 to 10 shown, a main shaft rotation device of a tool presetting instrument according to an embodiment of the present invention includes a rod base 1. A flange 3 is fixedly installed at the bottom of the rod base 1. A motor 7 is arranged inside the rod base 1. The output end of the motor 7 is fixedly installed with a main shaft 9. A tool presetting instrument 2 is arranged at the top of the main shaft 9. A plurality of tool placement grooves are opened inside the tool presetting instrument 2. A slide disk 10 is fixedly installed at the top of the rod base 1. The outer wall of the main shaft 9 penetrates through the inner wall of the slide disk 10 and is rotationally connected with the inner wall of the slide disk 10. An agent storage tank 5 and an agent placement tank 6 are fixedly installed outside the slide disk 10. The agent storage tank 5 is arranged directly above the agent placement tank 6. A replenishment assembly is arranged between the agent storage tank 5 and the agent placement tank 6. The replenishment assembly includes an absorbent cotton rod 604. The replenishment assembly is used to flow the lubricant placed in the agent placement tank 6 back into the agent storage tank 5 through the absorbent cotton rod 604. A lubricant replenishment assembly is arranged outside the agent storage tank 5. The lubricant replenishment assembly is used to replenish the lubricant inside the slide disk 10;

[0038] During production operations, in order to ensure the stability of the main shaft, it is necessary to frequently replenish the lubricant. When the existing lubricant is replenished, the lubricant is usually directly introduced, which is very easy to apply too much and is extremely easy to cause unnecessary waste during use;

[0039] First, fix the flange 3 at the designated position using bolts and nuts. Then, insert the tool presetting instrument 2 into the top of the main shaft 9. When both are installed, a complete rotating device is formed. When tool switching is required, control the motor 7 to rotate through the system. The motor 7 drives the tool presetting instrument 2 to rotate through the main shaft 9, so as to switch the position of the tool placed in the tool presetting instrument 2. When the main shaft 9 rotates, the lubricant storage tank 5 supplies lubricant into the sliding disk 10 through the oil replenishment component to ensure the activity of the lubricant in the sliding disk 10 and prevent the instability and inaccuracy of the main shaft 9 during rotation due to insufficient or dry lubricant in the sliding disk 10. At the same time, a part of the lubricant in the sliding disk 10 flows back into the lubricant storage tank 6. Finally, the lubricant in the lubricant storage tank 6 is circulated back into the lubricant storage tank 5 through the absorbent cotton rod 604 of the replenishment component to replenish the outflowing lubricant, reduce the waste of lubricant, save resources, avoid the one-time consumption of lubricant, and ensure its activity at the same time, so that it can be recycled and is more conducive to lubricating the sliding disk 10.

[0040] As Figures 2 to 3 shown, a balance disk 8 is fixedly installed on the outer wall of the main shaft 9, and a plurality of rotating shafts 4 are fixedly installed on the inner wall of the balance disk 8. A plurality of socket caps 201 are fixedly installed at the bottom of the tool presetting instrument 2, and the tops of the plurality of rotating shafts 4 are respectively slidably connected to the inside of the plurality of socket caps 201;

[0041] During installation, insert the plurality of rotating shafts 4 into the socket caps 201 at the bottom of the tool presetting instrument 2, and then insert the bottom of the tool presetting instrument 2 into the top of the main shaft 9. When the tool presetting instrument 2 needs to be rotated to switch tools, when the main shaft 9 rotates, the balance disk 8 and the plurality of rotating shafts 4 drive the tool presetting instrument 2 to rotate, which can improve the stability of the tool presetting instrument 2 during rotation and is more conducive to the tool presetting instrument 2 rotating to switch tools, preventing the tool presetting instrument 2 from shaking or wobbling when the main shaft 9 drives the tool presetting instrument 2 to rotate because it rotates around a fulcrum.

[0042] As Figures 3 to 4 shown, a connecting shaft is fixedly installed at the bottom of the tool presetting instrument 2. The connecting shaft is a cylinder. A plurality of retaining blocks 901 are slidably connected to the inner wall of the main shaft 9. A plurality of retaining springs 902 are arranged between one side of the plurality of retaining blocks 901 and the inner wall of the main shaft 9. The outer wall of the connecting shaft is slidably connected to the outer walls of the plurality of retaining blocks 901, and the outer walls of the plurality of retaining blocks 901 are all inclined sliding surfaces;

[0043] When the tool presetting instrument 2 is inserted into the spindle 9, by pressing down the tool presetting instrument 2, the connecting shaft at the bottom of the tool presetting instrument 2 pushes multiple retaining blocks 901 to move to both sides inside the spindle 9. When the connecting shaft at the bottom of the tool presetting instrument 2 completely enters the spindle 9, the connecting shaft can no longer move at this time, and multiple retaining blocks 901 will clamp the outer wall of the connecting shaft at the bottom of the tool presetting instrument 2 through the elastic force of the retaining spring 902, so as to fix it, realizing the installation of the tool presetting instrument 2 and the spindle 9, playing a role in facilitating installation. By moving multiple caps 201 to fix the tool presetting instrument 2, the spindle 9 can be installed with tool presetting instruments 2 of various different sizes.

[0044] As Figures 5 to 7 shown, multiple fluid pipes 501 are fixedly installed at the bottom of the storage tank 5. An annular ball groove 11 is formed in the inner wall of the sliding disk 10. One end of each of the multiple fluid pipes 501 is fixedly installed inside the annular ball groove 11. Through holes are symmetrically arranged at the top of the storage tank 5;

[0045] When the tool presetting instrument 2 is rotating, the lubricant in the storage tank 5 will flow into the annular ball groove 11 in the sliding disk 10 through the fluid pipes 501 under the drive of the oil replenishing assembly, so as to replenish the lubricant in the annular ball groove 11, preventing the lubricant in the annular ball groove 11 from being too little or having low activity and affecting the rotation of the tool presetting instrument 2, playing a role in replenishing the lubricant.

[0046] As Figures 6 to 7 shown, the bottom ends of multiple rotating shafts 4 are rotatably connected with ball blocks 402, and the outer walls of the multiple ball blocks 402 are slidably connected with the inner wall of the annular ball groove 11;

[0047] When the motor 7 drives the tool presetting instrument 2 to rotate through the rotating shaft 4 and the spindle 9, the ball block 402 at the bottom end of the rotating shaft 4 slides on the inner wall of the annular ball groove 11. Through the spherical setting of the ball block 402, the friction area between the rotating shaft 4 and the sliding disk 10 can be reduced, which is beneficial to the rotation of the rotating shaft 4 in the annular ball groove 11 and ensures the stability of the tool presetting instrument 2. When the rotating shaft 4 moves in the annular ball groove 11, the moving ball block 402 can also rotate on its own inside the annular ball groove 11, so that the lubricant introduced from the fluid pipe 501 can be applied to the whole body of the ball block 402, preventing the friction of the whole body of the ball block 402 from increasing due to the lack of lubricant application, affecting the stability of the rotating shaft 4 during rotation, and indirectly affecting the rotation of the tool presetting instrument 2.

[0048] As Figures 7 to 8As shown in the figure, the oil replenishing assembly includes a plugging agent rod 503. The number of plugging agent rods 503 is the same as the number of fluid pipes 501. The outer walls of multiple plugging agent rods 503 are respectively slidably connected to the inner walls of multiple fluid pipes 501. The tops of multiple plugging agent rods 503 are fixedly installed with bumps 502. The outer walls of multiple rotating shafts 4 are fixedly installed with extrusion blocks 401. The bottoms of multiple extrusion blocks 401 can respectively slidably connect with the tops of multiple bumps 502. The bottoms of multiple extrusion blocks 401 and the tops of multiple bumps 502 are both inclined sliding surfaces;

[0049] When the rotating shaft 4 rotates, the rotating shaft 4 drives the extrusion block 401 to rotate. When the extrusion block 401 rotates and contacts the bump 502, the extrusion block 401 squeezes the bump 502 downward, so that the bump 502 drives the plugging agent rod 503 to move downward and open in the fluid pipe 501. The lubricant placed in the storage tank 5 will flow into the annular ball groove 11 along the pipe wall of the fluid pipe 501 and the openings on the plugging agent rod 503 for lubricant replenishment. By controlling the lubricant replenishment through the rotation of the rotating shaft 4, the flow rate of the lubricant entering the annular ball groove 11 can be controlled, avoiding waste of resources caused by excessive lubricant input, and playing a role in controlling the flow rate of the lubricant input.

[0050] As Figures 1 to 2 shown in the figure, multiple hollow shafts are fixedly installed on the top of the agent placement box 6. The outer walls of multiple plugging agent rods 503 are respectively slidably connected to the inner walls of multiple hollow shafts. A return spring 504 is arranged between the bottom ends of multiple plugging agent rods 503 and the inner walls of multiple hollow shafts;

[0051] When the extrusion block 401 loses contact with the bump 502, the plugging agent rod 503 will rebound and reset under the elastic force of the return spring 504, and the plugging agent rod 503 will close the fluid pipe 501 to prevent the lubricant in the fluid pipe 501 from flowing out, playing a role in resetting the plugging agent rod 503 to block the outflow of the lubricant.

[0052] As Figures 1 to 2 shown in the figure, multiple return fluid pipes 602 are fixedly installed at the bottom end of the sliding disk 10. One end of each of the multiple return fluid pipes 602 penetrates the inner wall of the rod seat 1 and is placed inside the agent placement box 6. A fluid gathering ring block 601 is fixedly installed inside the agent placement box 6;

[0053] When the ball block 402 finishes rotating in the annular ball groove 11, the ball block 402 will stop rotating. The lubricant placed in the annular ball groove 11 will flow back into the agent placement box 6 along the return fluid pipes 602 and finally be placed between the fluid gathering ring blocks 601 for storage, playing a role in recycling the lubricant.

[0054] As Figures 1 to 2As shown, the replenishing component further includes a hollow rod 603. There are multiple hollow rods 603 and multiple absorbent cotton rods 604. The multiple absorbent cotton rods 604 are respectively placed inside the multiple hollow rods 603. The tops of the multiple absorbent cotton rods 604 are rotatably connected to the inner wall of the agent placing box 6, and the bottoms of the multiple absorbent cotton rods 604 are all placed at the inner groove of the agent concentrating ring block 601.

[0055] When the lubricant enters the agent concentrating ring block 601, since the absorbent cotton rod 604 is a fiber cotton rod, when the bottom end of the absorbent cotton rod 604 contacts the lubricant placed in the agent concentrating ring block 601, capillary action will occur on the absorbent cotton rod 604, so that the lubricant adsorbs and moves upward at the bottom of the absorbent cotton rod 604. The lubricant recovered into the agent placing box 6 will move into the storage agent box 5 for lubricant replenishment, playing the role of replenishing the lubricant. By using the absorbent cotton rod 604 as a fiber cotton rod, the lubricant can also be filtered to prevent impurities from being mixed in the outflowing lubricant, affecting subsequent use.

[0056] As Figures 1 to 2 As shown, push rods 403 are fixedly installed on the outer walls of the multiple rotating shafts 4. One ends of the multiple push rods 403 are rotatably connected to pressing cotton shafts 606. Arc-shaped panels 607 are fixedly installed on the tops of the multiple hollow rods 603. Multiple groups of shaft blocks 605 are rotatably connected to the inner wall of the agent placing box 6. The number of each group of shaft blocks 605 is three, and the three shaft blocks 605 are symmetrically arranged in a triangle outside the absorbent cotton rod 604. The outer walls of the multiple pressing cotton shafts 606 can respectively slide on the outer walls of the multiple absorbent cotton rods 604.

[0057] When the lubricant flows upward to the top end of the absorbent cotton rod 604 through capillary action, since the absorbent cotton rod 604 adsorbs the lubricant, the absorbent cotton rod 604 will expand. Therefore, when the lubricant is placed at the top end of the absorbent cotton rod 604, when the next rotating shaft 4 moves, the rotating shaft 4 drives the push rod 403 to rotate. When the push rod 403 rotates, the push rod 403 squeezes and pushes the top end of the absorbent cotton rod 604 to rotate. When the push rod 403 contacts the top end of the absorbent cotton rod 604, through the extrusion and pushing of the pressing cotton shaft 606 and the external restriction of the three shaft blocks 605, the lubricant placed at the top end of the absorbent cotton rod 604 will be squeezed out of the inside of the absorbent cotton rod 604, drip onto the arc-shaped panel 607 around the smooth shaft block 605, and finally fall into the storage agent box 5 for storage, playing the role of extracting the lubricant.

[0058] Working principle: First, use bolts and nuts to fix the flange 3 in the specified position, and then insert the tool presetter 2 into the top of the spindle 9. When the two are installed, a complete rotating device can be formed. When the tool needs to be switched, the system controls the motor 7 to rotate, so that the motor 7 drives the tool presetter 2 to rotate through the spindle 9, so that the tool placed in the tool presetter 2 is switched. When the spindle 9 rotates, the lubricant is introduced into the slide plate 10 through the oil replenishing component by the storage tank 5 to ensure that the slide plate 10 The activity of the internal lubricant prevents the stability and accuracy of the main shaft 9 when the lubricant in the sliding plate 10 is insufficient or dry, and at the same time, a part of the lubricant placed in the sliding plate 10 flows back to the agent box 6, and finally the lubricant placed in the agent box 6 is returned to the agent storage box 5 through the replenishment component through the absorbent cotton rod 604, so that the outflowing lubricant is replenished, reducing the waste of lubricant, saving resources, and avoiding the lubricant from being consumed once. At the same time, its activity can be guaranteed, and it can be recycled, which is more conducive to lubricating the sliding plate 10;

[0059] During installation, multiple rotating shafts 4 are inserted into the sleeve cap 201 at the bottom of the tool presetter 2, and then the bottom of the tool presetter 2 is inserted into the top of the spindle 9. When the tool presetter 2 needs to be rotated to switch the tool, the spindle 9 is rotated, and the tool presetter 2 is driven to rotate through the balancing plate 8 and multiple rotating shafts 4. This can improve the stability of the tool presetter 2 during rotation, and is more conducive to the tool presetter 2 rotating to switch the tool, and prevent the spindle 9 from driving the tool presetter 2 to rotate. Because the fulcrum rotates, the tool presetter 2 is prevented from shaking or swaying;

[0060] When the tool presetter 2 is inserted into the spindle 9, the tool presetter 2 is pressed down so that the connecting shaft at the bottom of the tool presetter 2 pushes the multiple retaining blocks 901 to move to both sides in the spindle 9. When the connecting shaft at the bottom of the tool presetter 2 is completely inserted into the spindle 9, the multiple retaining blocks 901 retain the connecting shaft at the bottom of the tool presetter 2 through the elastic force of the retaining spring 902, thereby realizing the installation of the tool presetter 2 and the spindle 9, which facilitates the installation. The tool presetter 2 is retained by moving the multiple sleeve caps 201, so that the spindle 9 can be installed with tool presetters 2 of various sizes.

[0061] When the tool presetter 2 is rotating, the lubricant in the reservoir 5 will flow into the annular ball groove 11 in the slide plate 10 through the fluid pipe 501, thereby replenishing the lubricant in the annular ball groove 11, preventing the lubricant in the annular ball groove 11 from being too little or having low activity and affecting the rotation of the tool presetter 2, thereby playing the role of replenishing the lubricant;

[0062] When the motor 7 drives the tool presetting instrument 2 to rotate through the rotating shaft 4 and the main shaft 9, the ball block 402 at the bottom end of the rotating shaft 4 slides on the inner wall of the annular ball groove 11. Due to the spherical setting of the ball block 402, the friction area between the rotating shaft 4 and the sliding disk 10 can be reduced, which is beneficial to the rotation of the rotating shaft 4 in the annular ball groove 11 and ensures the stability of the tool presetting instrument 2. When the rotating shaft 4 moves in the annular ball groove 11, the moving ball block 402 can also rotate automatically inside the annular ball groove 11, so that the lubricant introduced from the flow agent pipe 501 can be applied to the whole body of the ball block 402, preventing the friction from increasing due to the lack of lubricant application on the whole body of the ball block 402, which affects the stability of the rotating shaft 4 during rotation and indirectly affects the rotation of the tool presetting instrument 2;

[0063] When the rotating shaft 4 rotates, the rotating shaft 4 drives the extrusion block 401 to rotate. When the extrusion block 401 rotates and contacts the convex block 502, the extrusion block 401 squeezes the convex block 502 to move downward, so that the convex block 502 drives the plugging agent rod 503 to move downward in the flow agent pipe 501 to open. The lubricant placed in the storage agent box 5 will flow into the annular ball groove 11 along the pipe wall of the flow agent pipe 501 and the opening on the plugging agent rod 503 for lubricant replenishment. By controlling the lubricant replenishment through the rotation of the rotating shaft 4, the flow rate of the lubricant entering the annular ball groove 11 can be controlled, avoiding waste of resources caused by excessive lubricant introduction and playing a role in controlling the flow rate of the lubricant introduced;

[0064] When the extrusion block 401 loses contact with the convex block 502, the plugging agent rod 503 will rebound and reset under the elastic force of the return spring 504, and the plugging agent rod 503 will close the flow agent pipe 501 to prevent the lubricant in the flow agent pipe 501 from flowing out, playing a role in resetting the plugging agent rod 503 to block the outflow of the lubricant;

[0065] When the ball block 402 finishes rotating in the annular ball groove 11, the ball block 402 will stop rotating, and the lubricant placed in the annular ball groove 11 will flow back into the storage agent box 6 along the return agent pipe 602 and finally be placed between the agent collecting ring blocks 601 for storage, playing a role in recycling the lubricant;

[0066] When the lubricant enters the agent collecting ring block 601, since the absorbent cotton rod 604 is made of fibrous cotton rod, when the bottom end of the absorbent cotton rod 604 contacts the lubricant placed in the agent collecting ring block 601, capillary action will occur to the lubricant on the absorbent cotton rod 604, so that the lubricant adsorbs and moves upward from the bottom of the absorbent cotton rod 604. The lubricant recovered into the storage agent box 6 will move to the storage agent box 5 for lubricant replenishment, playing a role in replenishing the lubricant. By using the absorbent cotton rod 604 made of fibrous cotton rod, the lubricant can also be filtered to prevent impurities from being mixed in the recycled lubricant, affecting subsequent use;

[0067] When the lubricant flows upward to the top of the absorbent cotton rod 604 by capillary action, since the absorbent cotton rod 604 adsorbs the lubricant, the absorbent cotton rod 604 will expand. Therefore, when the lubricant is placed at the top of the absorbent cotton rod 604, when the rotating shaft 4 moves next time, the rotating shaft 4 drives the push rod 403 to rotate. When the push rod 403 rotates, the push rod 403 squeezes and pushes the top of the absorbent cotton rod 604 to rotate. When the push rod 403 contacts the top of the absorbent cotton rod 604, through the extrusion and pushing cooperation of the cotton pressing shaft 606 and the external restriction of the three shaft blocks 605, the lubricant placed at the top of the absorbent cotton rod 604 will be extruded out of the inside of the absorbent cotton rod 604, drip onto the arc-shaped panel 607 around the smooth shaft block 605, and finally fall into the inside of the storage tank 5 for storage, playing the role of extracting the lubricant.
