Description

Technical Field

[0001] This invention relates to the field of shaft machining technology, and more specifically to a machine tool for machining air-bearing spindles. Background Technology

[0002] An air-bearing spindle is a sliding bearing that uses gas as a lubricant. When machining its spindle parts, it is generally rough or semi-finished using an external cylindrical grinding machine. However, the external cylindrical grinding machine under the current technology still has the following shortcomings when machining spindle parts.

[0003] First, when the external cylindrical grinding machine grinds the spindle parts, the generated chips and abrasive particles will flow into the filtration system along with the cutting fluid for filtration. This waste liquid is a mixture of cutting fluid, metal chips and abrasive particles, with high water content and viscous form. Therefore, when the external cylindrical grinding machine uses traditional filter paper for filtration, the filtration effect is low and the viscous filter residue is difficult to handle.

[0004] Secondly, in the case of grinding spindle parts, the radial cutting force of the grinding wheel of the existing cylindrical grinding machine can easily cause deformation of the spindle bar, thus affecting the subsequent processing of product parts.

[0005] Therefore, in order to solve the above problems, it is necessary to provide an air-bearing spindle body machining device. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an air-bearing spindle body processing device to solve the problems existing in the background art.

[0009] When the left connecting rod extends, it causes the right connecting rod to retract; when the left connecting rod retracts, it causes the right connecting rod to extend; and the filter layer extends or retracts accordingly.

[0010] When the filter layer expands, it collects and filters the cutting fluid; when the filter layer contracts, it squeezes the filter residue, making the filtration more thorough.

An air pump is fixedly installed on the tailstock, and an air pipe is connected between the output end of the air pump and the internal cavity of the cavity arc cover.

[0020] The technical effects and advantages of this invention are as follows:

[0021] When in use, the waste liquid is discharged downwards from the movable plate. When the movable plate is directly above the left connecting rod, the left connecting rod is in the extended state, and the filter layer installed on it collects and filters the waste liquid. After the filter residue accumulates on the filter layer, the servo motor drives the movable belt to rotate, causing the movable plate and the intermediate moving plate to move towards each other. When the movable plate moves directly above the right connecting rod, the intermediate moving plate moves towards the left connecting rod, causing the left connecting rod to retract and the right connecting rod to extend. The filter layer installed on the right connecting rod begins to collect and filter the waste liquid. During the retraction process, the left connecting rod drives the filter layer installed on it to clamp. When the filter layer is clamped, the filter liquid can be squeezed out more fully. Moreover, there is more filter residue left at the corner of the filter layer. When the filter layer is clamped, the corner space is smaller, and the squeezing is more thorough, thus making the filtration more thorough. The left and right connecting rods alternately extend and retract, which improves the filtration effect of the cutting fluid.

[0022] A magnetic suction plate is installed between the bottom angles of adjacent inclined surfaces of the filter layer. When the waste liquid is filtered, the filter residue mixed with metal fragments is magnetic and thus adsorbed onto the magnetic suction plate. When the filter layers on both sides of the magnetic suction plate shrink and clamp together, the magnetic suction plate is located in the middle, which can reduce and widen the clamping space, thereby making the filter residue more thoroughly compressed. The compressed filter residue will be adsorbed onto the magnetic suction plate. The staff can open the window and door to remove the magnetic suction plate from the frame for cleaning, and install or replace it through the sludge removal window. The above method can realize the convenience of the device in handling filter residue.

[0023] When the tip is fixed to the bar stock, the pull lug can be pulled out to cover the opposite side of the bar stock's grinding position. When the grinding wheel generates radial cutting force on the bar stock during grinding, the air pump can blow air into the cavity arc cover. The airflow is blown out from the air nozzle, providing thrust compensation on the other side of the bar stock's grinding position, thereby preventing the bar stock from deforming during grinding. In addition, the blown airflow can clean up the debris generated during grinding, preventing it from adhering to the surface of the bar stock and affecting its grinding operation.

When the upper clamping plate 716 moves to one side of the frame plate 704, the lower clamping plate 718 moves to the other side of the frame plate 704.

[0041] Left connecting rods 701 are movably connected from one end to the other between the bottom two sides of the movable plate 708 and the bottom two sides of the left fixed plate 709.

Filter layers 703 are installed on both the left connecting rods 701 and the right connecting rods 702.

[0042] A rear side plate 720 is installed on the bottom outer side of the track plate 707. A limiting groove 721 is provided on the rear side plate 720. The ends of the shafts connecting the left connecting rod 701 and the right connecting rod 702 are movably connected in the limiting groove 721. A sliding groove 722 is also provided on the rear side plate 720. A uniformly distributed sleeve 723 is movably sleeved on the sliding groove 722. Each sleeve 723 is located between the bottom angles of adjacent inclined surfaces of the filter layer 703. A magnetic suction plate 724 is sleeved on each sleeve 723.

[0043] A front side plate 725 is installed on the bottom outer side of the track plate 707. A movable groove is provided on the front side plate 725. The lower connecting plate 719 is movably fitted into the movable groove. Sealing folding plates 726 are connected between the two sides of the lower connecting plate 719 and the two ends of the movable groove. Sewage windows are provided on both sides of the front side plate 725. The sewage windows are aligned with the retracted positions of the left connecting rod 701 and the right connecting rod 702, respectively. A shaft support 727 is fixedly installed on the outer side of the sewage window. The shaft support 727 is movably connected to a window door 728 through a rotating shaft.

A water outlet pipe 730 is fixedly connected to the outer side of the bottom compartment 729.

[0044] When the device is in use, waste liquid is discharged downwards from the movable plate 705. When the movable plate 705 is directly above the left connecting rod 701, the left connecting rod 701 is in the extended state, and the filter layer 703 installed on it collects and filters the waste liquid. After the filter residue accumulates on the filter layer 703, the servo motor 711 drives the movable belt 715 to rotate, thereby causing the movable plate 705 and the intermittent moving plate 708 to move towards each other. The movable plate 705 moves to directly above the right connecting rod 702, and the intermittent moving plate 708 moves to the side of the left connecting rod 701, thereby causing the left connecting rod... 701 retracts, causing the right connecting rod 702 to unfold. The filter layer 703 installed on the right connecting rod 702 begins to collect and filter the waste liquid. During the retraction process, the left connecting rod 701 drives the filter layer 703 installed on it to clamp. When the filter layer 703 is clamped, the filtrate can be squeezed out more fully. Moreover, there is more filter residue at the corner of the filter layer 703. When it is clamped, the corner space is smaller, and the squeezing is more thorough, thus making the filtration more thorough. The left connecting rod 701 and the right connecting rod 702 alternately unfold and retract, which improves the filtration effect of the device on the cutting fluid.

[0045] A magnetic suction plate 724 can be installed between the bottom angles of adjacent inclined surfaces of the filter layer 703. When the waste liquid is filtered, the filter residue mixed with metal fragments is magnetic and thus adsorbs onto the magnetic suction plate 724. When the filter layers 703 on both sides of the magnetic suction plate 724 contract and clamp, the magnetic suction plate 724 is located in the middle, which can reduce and increase the clamping space, thereby making the filter residue more thoroughly compressed. The compressed filter residue will be adsorbed onto the magnetic suction plate 724. The staff can open the window 728 to remove the magnetic suction plate 724 from the frame 723 for cleaning, and install or replace it through the sludge removal window. The above method can realize the convenience of the device in handling filter residue.

[0046] It should be further explained that, since the filter layer 703 is arranged in a folded manner, there is a top angle and a bottom angle between the adjacent inclined surfaces of the filter layer 703. When the filter layer 703 contracts or expands, its inclined surfaces can push the magnetic suction plate 724 to concentrate or disperse accordingly. When the filter layer 703 expands, the height of the top angle between the adjacent inclined surfaces of the filter layer 703 is still higher than the bottom of the magnetic suction plate 724. This ensures that the magnetic suction plate 724 will not cross the inclined surface of the filter layer 703 and enter the other angle space, thus maintaining the uniformity of the distribution of the magnetic suction plate 724.

[0047] Reference Figure 2 The tailstock assembly 8 includes a tail platform 801, which is fixedly installed on the movable platform 103. A horizontal rail 802 is provided on the tail platform 801, and a tailstock component 803 is movably installed on the horizontal rail 802. A third bearing 804 is fixedly installed at both ends of the tail platform 801. A third lead screw 805 is movably sleeved between the third bearings 804. The third lead screw 805 is threadedly sleeved with the tailstock component 803. A third rotating wheel 806 is installed at the end of the shaft of the third lead screw 805. A center 807 is installed on the tailstock component 803, and the axis of the center 807 coincides with the axis of the bar stock 3.

[0048] When in use, the device drives the third lead screw 805 to rotate, which adjusts the position of the tailstock 803, thereby fixing the tip 807 to the end axis of the bar stock 3, making it more stable during rotary grinding.

[0049] Reference Figure 7 and Figure 8 The air blowing compensation mechanism 9 includes a sleeve 901, which is mounted on the tailstock 803. A cavity arc cover 902 is movably sleeved in the sleeve 901. The axis of the cavity arc cover 902 coincides with the axis of the tip 807. An adjustment groove is provided on the sleeve 901. A pull lug 903 is fixedly installed on the outer side of the cavity arc cover 902. The pull lug 903 is movably sleeved on the adjustment groove. Air nozzles 904 are evenly distributed on the inner arc surface of the cavity arc cover 902. The air nozzles 904 communicate with the internal cavity of the cavity arc cover 902. An air pump 905 is fixedly installed on the tailstock 803. An air pipe 906 is connected between the output end of the air pump 905 and the internal cavity of the cavity arc cover 902.

[0050] When the device is in use, when the tip 807 fixes the bar stock 3, the pull lug 903 can be pulled out to cover the opposite side of the grinding position of the bar stock 3. When the grinding wheel 5 generates radial cutting force on the bar stock 3 during grinding, the air pump 905 can blow air into the cavity arc cover 902. The airflow is blown out from the air nozzle 904, which provides thrust compensation on the other side of the grinding position of the bar stock 3, thereby preventing the bar stock 3 from deforming during grinding. In addition, the blown airflow can clean up the debris generated during grinding and prevent it from adhering to the surface of the bar stock 3, thus affecting its grinding work.

[0051] The working principle of this invention is as follows: During use, waste liquid is discharged downwards from the movable plate 705. When the movable plate 705 is directly above the left connecting rod 701, the left connecting rod 701 is in an extended state. The filter layer 703 installed on it collects and filters the waste liquid. When filter residue accumulates on the filter layer 703, the servo motor 711 drives the movable belt 715 to rotate, causing the movable plate 705 and the intermittently moving plate 708 to move towards each other. The movable plate 705 moves to directly above the right connecting rod 702, and the intermittently moving plate 708 moves towards the left connecting rod 701, thereby... The left connecting rod 701 retracts, causing the right connecting rod 702 to unfold. The filter layer 703 installed on the right connecting rod 702 begins to collect and filter the waste liquid. During the retraction process, the left connecting rod 701 drives the filter layer 703 installed on it to clamp. When the filter layer 703 is clamped, the filtrate can be squeezed out more fully. Moreover, there is more filter residue at the corner of the filter layer 703. When it is clamped, the corner space is smaller, and the squeezing is more thorough, thus making the filtration more thorough. The left connecting rod 701 and the right connecting rod 702 unfold and retract alternately, which improves the filtration effect of the device on the cutting fluid.

[0052] A magnetic suction plate 724 can be installed between the bottom angles of adjacent inclined surfaces of the filter layer 703. When the waste liquid is filtered, the filter residue mixed with metal fragments is magnetic and thus adsorbs onto the magnetic suction plate 724. When the filter layers 703 on both sides of the magnetic suction plate 724 contract and clamp, the magnetic suction plate 724 is located in the middle, which can reduce and increase the clamping space, thereby making the filter residue more thoroughly compressed. The compressed filter residue will be adsorbed onto the magnetic suction plate 724. The staff can open the window 728 to remove the magnetic suction plate 724 from the frame 723 for cleaning, and install or replace it through the sludge removal window. The above method can realize the convenience of the device in handling filter residue.

[0053] When the tip 807 fixes the bar stock 3, the pull lug 903 can be pulled out to cover the opposite side of the grinding position of the bar stock 3. When the grinding wheel 5 generates radial cutting force on the bar stock 3 during grinding, the air pump 905 can blow air into the cavity arc cover 902. The airflow is blown out from the air nozzle 904, which provides thrust compensation on the other side of the grinding position of the bar stock 3, thereby preventing the bar stock 3 from deforming during grinding. The blown airflow can also clean up the debris generated during grinding and prevent it from adhering to the surface of the bar stock 3, thus affecting its grinding work.
