Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0038] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a grinding machine for simultaneously grinding the inner and outer channels of a long and narrow guide rail, including a base 1, symmetrically and fixedly connected with sliding rods 2 at the top of the base 1, a guide rail fixing plate 3 is slidably connected between the left sides of the two sliding rods 2, a cushion plate 4 is slidably connected between the right sides of the two sliding rods 2, pulley rods 5 are rotatably connected to both ends of the cushion plate 4 and both ends of the guide rail fixing plate 3, an electric push rod 6 is fixedly connected to the top surface of the base 1, and one end of the electric push rod 6 is fixedly connected to the side wall of the guide rail fixing plate 3. It should be noted that: clamping blocks are provided on the guide rail fixing plate 3 to facilitate clamping and fixing of the long and narrow guide rail.

[0039] Chutes 7 are provided on both the front and rear sides of the top of the base 1. A sliding plate 8 is slidably connected inside the chute 7. Oblique grooves 9 are symmetrically provided on the side wall of the sliding plate 8. The pulley rod 5 is slidably connected inside the adjacent oblique groove 9. It should be noted that: balls are provided on the inner wall of the chute 7, and the surface of the balls is lapped with the side wall of the sliding plate 8 to reduce the frictional resistance when the sliding plate 8 moves; and the two oblique grooves 9 are symmetrically arranged. When the sliding plate 8 moves up and down, the adjacent two pulley rods 5 can move away from or towards each other. Thus, when the electric push rod 6 pushes the guide rail fixing plate 3 towards the cushion plate 4, the cushion plate 4 will also translate towards the guide rail fixing plate 3.

[0040] Blocks 10 are symmetrically and fixedly connected to the top of the cushion plate 4. A screw rod 11 is rotatably connected between the two blocks 10. The middle of the screw rod 11 is movably connected with a connecting plate 12. The bottom of the connecting plate 12 is fixedly connected with an arc-shaped support sleeve 13. It should be noted that: a round rod is fixedly connected between the sides of the two blocks 10 away from the screw rod 11. A screw sleeve and a cylinder are fixedly connected to the top of the connecting plate 12. The screw sleeve is threadedly connected with the screw rod 11. The cylinder is slidably connected to the surface of the round rod. One end of the screw rod 11 penetrates through the block 10 and is fixedly connected with a driving motor. The side wall of the driving motor is fixedly connected with the side wall of the adjacent block 10. When the screw rod 11 rotates, the connecting plate 12 drives the arc-shaped support sleeve 13 to move. The screw rod 11 is a reciprocating screw rod. This is a common transmission component and belongs to the prior art, so it will not be described in detail here.

[0041] A grinding motor 14 is movably connected to the top of the arc-shaped support sleeve 13. The rotating end of the grinding motor 14 is fixedly connected with a transmission rod 15. The bottom of the transmission rod 15 is movably connected to the inner bottom surface of the arc-shaped support sleeve 13. It should be noted that: the bottom of the transmission rod 15 penetrates through the upper part of the arc-shaped support sleeve 13 and is fixedly sleeved with a transmission bearing. The outer ring of the bottom of the transmission bearing is fixedly connected with a moving block. The bottom of the moving block is slidably connected to the inner bottom surface of the arc-shaped support sleeve 13; and an adjustment groove matching with the waist-shaped groove 1607 is provided on the top of the arc-shaped support sleeve 13, which is convenient for the inner groove grinding wheel 1602 on the main clamping sleeve 1601 to drive the transmission rod 15 to move after being pressed, avoiding interference. And a bracket is movably connected to the top of the arc-shaped support sleeve 13, and the grinding motor 14 is fixedly installed on the bracket to improve the use stability of the grinding motor 14.

[0042] A grinding mechanism 16 is movably connected between the inner wall of the arc-shaped support sleeve 13 and the transmission rod 15. Limiting mechanisms 17 are symmetrically and movably connected to the inner top surface of the arc-shaped support sleeve 13. The two limiting mechanisms 17 respectively correspond to the two sides of the grinding mechanism 16 one by one.

[0043] There is a cooling mechanism 18 movably connected between the top of the arc-shaped support sleeve 13 and the transmission rod 15. On the right side of the base 1, there is a fixed connection with a coolant tank 19. On the top of the coolant tank 19, there is a fixed connection with an infusion pipe 20. One end of the infusion pipe 20 is fixedly connected to one end of the cooling mechanism 18. It should be noted that: there is a booster pump between the coolant tank 19 and the infusion pipe 20. When the cooling device is turned on, the pressurized coolant flows out from the inside of the coolant tank 19; and the infusion pipe 20 is set as a telescopic hose.

[0044] In this embodiment, as Figures 1 to 9 shown, the grinding mechanism 16 includes a main clamping sleeve 1601. The main clamping sleeve 1601 is rotatably connected to the lower part of the transmission rod 15. Inside the main clamping sleeve 1601, there is a movably connected internal groove grinding wheel 1602. The inner ring of the internal groove grinding wheel 1602 is fixedly connected to the outer wall of the transmission rod 15. On the side wall of the main clamping sleeve 1601, there are symmetrically fixed connection with guide rods 1603. The right end of the guide rod 1603 is movably inserted through the right side of the arc-shaped support sleeve 13. Between the left side of the guide rod 1603 and the arc-shaped support sleeve 13, there is a movably connected compression spring 1604. It should be noted that: the cross-section of the main clamping sleeve 1601 is set as U-shaped. On the top and bottom of the main clamping sleeve 1601, there are circular holes. Between the inner ring of the circular holes and the surface of the transmission rod 15, there is a fixed connection with support bearings, so that during the rotation of the transmission rod 15, it can only drive the internal groove grinding wheel 1602 to rotate, and will not drive the main clamping sleeve 1601 to rotate.

[0045] On the upper part of the side wall of the arc-shaped support sleeve 13, there are symmetrically movably connected positioning rods 1605. Between the left ends of the two positioning rods 1605, there is a fixed connection with a secondary clamping sleeve 1606. In the middle of the secondary clamping sleeve 1606, there is a waist-shaped groove 1607. The upper part of the transmission rod 15 is movably inserted through the inside of the waist-shaped groove 1607. It should be noted that: the secondary clamping sleeve 1606 is arranged on the upper part of the main clamping sleeve 1601.

[0046] On the upper part of the transmission rod 15, there is a fixedly sleeved main guide wheel 1608. On the left and right sides of the secondary clamping sleeve 1606, there are rotatably connected shaft rods 1609. On the top of the shaft rod 1609, there is a fixed connection with a secondary guide wheel 1610. Between the two secondary guide wheels 1610 and the main guide wheel 1608, there is a movably connected transmission belt 1611. It should be noted that: through the cooperation of the two secondary guide wheels 1610 and the transmission belt 1611, when the position of the secondary clamping sleeve 1606 changes, it can still be transmitted through the cooperation of the transmission belt 1611 and the main guide wheel 1608 on the transmission rod 15; between the shaft rod 1609 and the secondary clamping sleeve 1606, there is a fixed connection with a connecting bearing to improve the rotational stability of the shaft rod 1609.

[0047] A groove 1612 matching with the corresponding shaft rod 1609 is provided on the left side of the jacket 1606. An external groove grinding wheel 1613 is movably connected inside the groove 1612. The inner ring of the external groove grinding wheel 1613 is fixedly connected to the middle part of the corresponding shaft rod 1609. Limiting racks 1614 are symmetrically and fixedly connected to both the bottom of the jacket 1606 and the top of the main jacket 1601.

[0048] Support bars 1615 are symmetrically and fixedly connected to the inner wall of the arc-shaped support sleeve 13. A connecting rod 1616 is rotatably connected to one side of the support bar 1615. A circular gear 1617 is fixedly sleeved at one end of the connecting rod 1616. The top and bottom of the circular gear 1617 are respectively meshed with the side walls of two adjacent limiting racks 1614. A worm gear 1618 matching with the limiting mechanism 17 is fixedly sleeved at the other end of the connecting rod 1616.

[0049] In this embodiment, as Figures 1 to 9 shown, the right end of the guide rod 1603 penetrates through the arc-shaped support sleeve 13 and is fixedly connected with a guide block. The compression spring 1604 is movably sleeved on the left side of the guide rod 1603. It should be noted that the movement of the guide rod 1603 and the main jacket 1601 is limited by the setting of the guide block.

[0050] In this embodiment, as Figures 1 to 9 shown, a limiting bearing is fixedly sleeved in the middle of the connecting rod 1616. The outer ring of the limiting bearing is fixedly connected to the inner wall of the support bar 1615. It should be noted that the setting of the limiting bearing improves the stability of the rotation of the connecting rod 1616.

[0051] In this embodiment, as Figures 1 to 9 shown, the limiting mechanism 17 includes an electric telescopic rod 1701. The electric telescopic rod 1701 is fixedly connected to the inner top surface of the arc-shaped support sleeve 13. A support block 1702 is fixedly connected to the bottom of the electric telescopic rod 1701. A worm 1703 matching with the grinding mechanism 16 is fixedly connected to the bottom of the support block 1702. It should be noted that when the support block 1702 drives the worm 1703 to move down and meshes with the adjacent worm gear 1618, the fixedly arranged worm 1703 locks the worm gear 1618, the connecting rod 1616 and the circular gear 1617 at this time, so that the positions of the external groove grinding wheel 1613 and the internal groove grinding wheel 1602 can be effectively locked after automatic adjustment, improving the grinding stability.

[0052] In this embodiment, as Figures 1 to 9As shown in the figure, the temperature reduction mechanism 18 includes a toothed ring 1901. The toothed ring 1901 is movably sleeved on the upper part of the transmission rod 15. Eight limiting blocks 1902 are movably connected to the inner ring of the toothed ring 1901 at equal intervals along the circumference. Eight limiting grooves 1903 are provided on the upper part of the transmission rod 15 at equal intervals along the circumference. The eight limiting blocks 1902 are respectively movably inserted into the eight limiting grooves 1903. It should be noted that the cross-section of the limiting block 1902 is set as a rectangle to prevent the limiting block 1902 from rotating within the toothed ring 1901 and affecting the cooperation with the limiting groove 1903.

[0053] Support rings 1904 are symmetrically and fixedly connected to the top of the arc-shaped support sleeve 13. An adjusting rod 1905 is slidably connected between the two support rings 1904. An adjusting rack 1906 is fixedly connected to the middle of the adjusting rod 1905. The side wall of the adjusting rack 1906 is meshed with the outer wall of the toothed ring 1901.

[0054] U-shaped limiting plates 1907 are fixedly connected to both ends of the adjusting rod 1905. A U-shaped liquid guide pipe 1908 is fixedly connected to the top of the arc-shaped support sleeve 13. Nozzles 1909 are fixedly connected to both ends of the U-shaped liquid guide pipe 1908 through the top of the arc-shaped support sleeve 13. Press valves 1910 are fixedly installed on both sides of the U-shaped liquid guide pipe 1908. The two press valves 1910 respectively correspond to the two U-shaped limiting plates 1907. The right end of the U-shaped liquid guide pipe 1908 is fixedly connected to one end of the infusion pipe 20. It should be noted that the press valve 1910 is a prior art and will not be described in detail here. When the U-shaped limiting plate 1907 presses against the position of the press valve 1910, the press valve 1910 opens, so that the coolant inside the U-shaped liquid guide pipe 1908 is sprayed out from the position of the nozzle 1909, and the coolant is sprayed on the positions of the outer groove grinding wheel 1613 and the inner groove grinding wheel 1602.

[0055] In this embodiment, as Figures 1 to 9As shown in the figure, eight moving grooves are equidistantly arranged along the circumference of the inner ring of the gear ring 1901. Eight limiting blocks 1902 are respectively slidably connected inside the eight moving grooves. An extrusion spring is fixedly connected between the inner wall of the moving groove and the side wall of the limiting block 1902, and the side wall of the limiting block 1902 is set as an inclined surface. It should be noted that when the gear ring 1901 is in a meshed state with the adjusting rack 1906, under the action of the inclined surface, the driving rod 15 cannot drive the gear ring 1901 to rotate when it rotates clockwise. When the driving rod 15 rotates counterclockwise for grinding, the driving rod 15 drives the gear ring 1901 to rotate through the cooperation of the limiting groove 1903 and the limiting block 1902, so that the gear ring 1901 meshes and drives with the adjusting rack 1906. At this time, the adjusting rack 1906 drives the adjusting rod 1905 and the U-shaped limiting plate 1907 to move, so that the U-shaped limiting plate 1907 presses against the corresponding pressing valve 1910. At this time, the pressing valve 1910 is opened for temperature reduction treatment; when the adjusting rack 1906 drives the adjusting rod 1905 to move to the limit position, under the action of the rotating gear ring 1901, the U-shaped limiting plate 1907 on the adjusting rod 1905 is always in a state of pressing against the pressing valve 1910.

[0056] In this embodiment, as Figures 1 to 9 shown, an installation ring is fixedly sleeved in the middle of the adjusting rod 1905. A spring telescopic rod is fixedly connected to the side wall of the installation ring. The adjusting rack 1906 is fixedly connected to one end of the spring telescopic rod. A adjusting spring is movably sleeved in the middle of the adjusting rod 1905. One end of the adjusting spring abuts against the side wall of the adjacent support ring 1904, and the other end of the adjusting spring abuts against the surface of the installation ring. It should be noted that when the driving rod 15 stops rotating, the adjusting spring presses the adjusting rod 1905 and the adjusting rack 1906 to reset, and at this time, the gear ring 1901 will not drive the driving rod 15 to rotate during the clockwise rotation, so that the U-shaped limiting plate 1907 resets and releases the extrusion on the pressing valve 1910; when the driving rod 15 drives the gear ring 1901 to move, the spring telescopic rod presses the adjusting rack 1906 to always be able to mesh with the outer wall of the gear ring 1901.

At this time, the pulley rods 5 at both ends of the guide rail fixing plate 3 slide inside the inclined grooves 9 on the two sliding plates 8, so that the sliding plates 8 slide upward inside the sliding grooves 7. At this time, the backing plate 4 drives the arc-shaped support sleeve 13 to move towards the guide rail;

[0059] When the inner groove of the guide rail fits against the side wall of the inner groove grinding wheel 1602 on the arc-shaped support sleeve 13, the position of the inner groove of the guide rail can be ground. As the guide rail fixing plate 3 and the backing plate 4 continue to move relative to each other, at this time, the inner groove grinding wheel 1602 is squeezed and drives the main collet 1601 to move towards the right side of the inner wall of the arc-shaped support sleeve 13. During the movement of the main collet 1601, the rack at the top of the main collet 1601 meshes with the bottom of the circular gear 1617, causing the rack at the bottom of the sub-collet 1606 to mesh with the top of the circular gear 1617 for transmission. Then, the sub-collet 1606 moves towards the guide rail, making the outer groove grinding wheel 1613 on the left side of the sub-collet 1606 fit against the outer groove on the guide rail;

[0060] Then start the two electric telescopic rods 1701, so that the electric telescopic rods 1701 drive the support blocks 1702 and the worm gears 1703 to move downward. The two fixedly arranged worm gears 1703 are respectively engaged with the two worm wheels 1618 to lock the rotation of the worm wheels 1618. At this time, the connecting rods 1616 on the worm wheels 1618 and the circular gear 1617 cannot rotate, making the positions of the main collet 1601 and the sub-collet 1606 in a locked state;

[0061] Next, start the grinding motor 14 to drive the transmission rod 15 to rotate counterclockwise, so that the transmission rod 15 drives the inner groove grinding wheel 1602 to rotate. At the same time, the main guide wheel 1608 on the upper part of the transmission rod 15 and the sub-guide wheel 1610 on the shaft rod 1609 are driven by the transmission belt 1611, so that the outer groove grinding wheel 1613 rotates accordingly, and the inner groove and outer groove of the guide rail are ground simultaneously;

[0062] When the transmission rod 15 rotates for grinding, through the cooperation of the limit groove 1903 and the limit block 1902, the transmission rod 15 drives the toothed ring 1901 to rotate synchronously. At this time, the toothed ring 1901 meshes with the adjusting rack 1906, causing the adjusting rack 1906 to drive the adjusting rod 1905 and the two U-shaped limit plates 1907 to translate, so that the U-shaped limit plates 1907 press against the corresponding pressing valves 1910. At this time, the pressing valves 1910 are opened, and the coolant is sprayed from the nozzle 1909 position on the U-shaped liquid guide pipe 1908 to cool the surface of the ground guide rail.
