Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to a track device for improving the linear accuracy of grinding machines. Background Technology

[0002] Grinding machines, as precision machining equipment, play a crucial role in industrial production and are widely used for high-precision grinding of various workpiece surfaces. Their core working principle relies on the relative motion between the grinding wheel (such as a high-speed rotating grinding wheel, oilstone, or abrasive belt) and the workpiece to achieve minute material removal and improve surface quality. In this process, the guide rail system, as a key component supporting and adjusting the relative position of the grinding wheel and workpiece, directly affects the accuracy and efficiency of the grinding process.

[0003] However, in practical applications, the guide rail system bears loads and operates at high speeds for extended periods, which easily leads to increased friction between the friction pairs. This not only accelerates guide rail wear, reduces equipment accuracy and lifespan, but also increases energy consumption and affects processing efficiency. To alleviate this problem, the traditional approach is to manually add lubricant to the guide rail surface periodically to reduce friction and maintain good operating conditions. However, the existing method of manually adding lubricant is time-consuming and labor-intensive, and performing manual operation in a high-speed machine tool environment poses high safety risks, which is detrimental to safe production. Utility Model Content

[0004] The purpose of this invention is to provide a track device for improving the linear accuracy of grinding machines, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a track device for improving the linear accuracy of a grinding machine, comprising a slide rail, a lead screw rotatably connected to the inner wall of the slide rail, a motor fixed to the left end of the slide rail, the output shaft of the motor passing through the slide rail and fixed to the surface of the lead screw, a top plate fixed to the top of the slide rail, a support rod fixed to the bottom of the top plate, a base fixed to the bottom of the support rod, and an automatically lubricating lubrication assembly provided on the surfaces of the top plate and the slide rail, the lubrication assembly comprising:

[0006] A stabilizing plate is fixed to the top of the top plate, and an oil storage tank is fixed to the bottom of the stabilizing plate. A fixing frame is fixed to the left end of the oil storage tank.

[0007] Preferably, the lubrication assembly further includes a piston rod that passes through a fixed frame. A sealing ring is fixed to the surface of the piston rod, and the piston rod is connected to the fixed frame piston via the sealing ring. A spring is fixed to the surface of the piston rod, and the end of the spring away from the piston rod is fixed to the surface of the fixed frame. A push rod is fixed to the left end of the piston rod, and the left end of the push rod passes through a slide rail, with the push rod slidably connected to the slide rail. A cavity is formed inside the piston rod, and a spring is fixed to the inner wall of the cavity. A ball is fixed to the end of the spring away from the cavity. A through hole is formed at the right end of the piston rod, and a through hole is formed on the surface of the piston rod. A through hole is formed at the left end of the oil reservoir. Third, a fixing plate is fixed to the inner wall of the fixed frame, and a spring three is fixed to the surface of the fixing plate. A ball two is fixed to the end of the spring three away from the fixing plate. The moving seat abuts against the top rod, and the top rod drives the piston rod to move to the right. Under pressure, the ball one disengages from the through hole one, the spring two is compressed, and the lubricant in the fixed frame enters the cavity. The lubricant in the cavity enters the guide tube and spray pipe through the through hole two, and can be sprayed onto the surface of the lead screw for lubrication. When the moving seat does not abut against the top rod, the spring one is released, and the piston rod returns to its original position. At this time, the pressure causes the spring two to drive the ball one to return to its original position, and at the same time the spring three is compressed, and the ball two disengages from the through hole three, so that the lubricant in the oil tank can enter the fixed frame.

[0008] Preferably, a conduit is fixed to the top of the fixed frame, and a spray pipe is connected to the surface of the end of the conduit away from the fixed frame. The end of the spray pipe away from the conduit passes through the top plate and the slide rail, and the conduit is interconnected with the fixed frame.

[0009] Preferably, the lead screw passes through a movable seat, the movable seat is threadedly connected to the lead screw, the movable seat is slidably connected to the slide rail, a cylinder is fixed at the bottom of the movable seat, a second motor is fixed at the bottom of the output end of the cylinder, and a grinding head is fixed at the bottom of the output shaft of the second motor. By controlling the first motor to rotate forward or reverse, the lead screw rotates, which allows the movable seat to move left and right. Starting the second motor and the cylinder allows grinding to be performed.

[0010] Preferably, the top of the oil tank is connected to a knob for easy addition of lubricant.

[0011] Preferably, the oil reservoir is filled with lubricating fluid to facilitate lubrication of the lead screw and the moving seat.

[0012] Preferably, a clamp is installed on the top of the base to facilitate fixing the workpiece.

[0013] Compared with the prior art, this utility model provides a track device for improving the linear accuracy of grinding machines, which has the following beneficial effects:

[0014] 1. This track device for improving the linear accuracy of grinding machines, through its lubrication components, causes the moving seat to contact the push rod, and the piston rod to move to the right. Under pressure, ball one disengages from through hole one, allowing lubricant in the fixed frame to enter the cavity. The lubricant in the cavity then enters the guide tube and spray pipe through through hole two, spraying onto the surface of the lead screw for lubrication. When the moving seat is no longer in contact with the push rod, spring one releases, and the piston rod returns to its original position. At this time, pressure causes spring two to move ball one back to its original position, while spring three compresses, disengaging ball two from through hole three. This allows lubricant in the oil tank to enter the fixed frame. Thus, during the reciprocating motion of the moving seat, lubricant can be repeatedly sprayed onto the surface of the lead screw, eliminating the need for manual replenishment, improving efficiency, preventing guide rail wear during prolonged operation, and enhancing equipment accuracy and service life.

[0015] 2. The track device that improves the linear accuracy of the grinding machine can clamp the workpiece with the set fixture to prevent the workpiece from shifting during grinding. Attached Figure Description

[0024] A stabilizing plate 807 is fixed to the top of the top plate 7. An oil reservoir 80 is fixed to the bottom of the stabilizing plate 807. A fixing frame 800 is fixed to the left end of the oil reservoir 80. The lubrication assembly 8 also includes a piston rod 81, which passes through the fixing frame 800. A sealing ring 87 is fixed to the surface of the piston rod 81. The piston rod 81 is connected to the fixing frame 800 via the sealing ring 87. A spring 82 is fixed to the surface of the piston rod 81. The end of the spring 82 away from the piston rod 81 is fixed to the fixing frame 800. On the surface of the oil reservoir 80, a push rod 83 is fixed to the left end of the piston rod 81. The left end of the push rod 83 passes through the slide rail 1 and is slidably connected to the slide rail 1. A cavity 84 is opened inside the piston rod 81. A spring 85 is fixed to the inner wall of the cavity 84. A ball 86 is fixed to the end of the spring 85 away from the cavity 84. A through hole 88 is opened at the right end of the piston rod 81. A through hole 89 is opened on the surface of the piston rod 81. A through hole 801 is opened at the left end of the oil reservoir 80. The fixed frame 8 A fixing plate 804 is fixed to the inner wall of the frame 800. A spring 803 is fixed to the surface of the fixing plate 804. A ball 802 is fixed to the end of the spring 803 away from the fixing plate 804. A conduit 805 is fixed to the top of the frame 800. A spray pipe 806 is connected to the surface of the end of the conduit 805 away from the frame 800. The end of the spray pipe 806 away from the conduit 805 passes through the top plate 7 and the slide rail 1. The conduit 805 communicates with the frame 800. The movable seat 4 abuts against the top rod 83. Rod 83 drives piston rod 81 to move to the right, spring 82 is compressed, and ball 86 disengages from through hole 88 under pressure. Spring 85 is compressed, and lubricant in the fixed frame 800 enters cavity 84. Lubricant in cavity 84 enters guide tube 805 and spray pipe 806 through through hole 89, and can be sprayed onto the surface of lead screw 2 for lubrication. No manual addition is required, which improves efficiency and avoids guide rail wear during long-term operation, thus improving equipment accuracy and service life.

[0025] A lead screw 2 passes through a movable seat 4, which is threadedly connected to the lead screw 2. The movable seat 4 is slidably connected to the slide rail 1. A cylinder 5 is fixed to the bottom of the movable seat 4, and a second motor 6 is fixed to the bottom of the output end of the cylinder 5. A grinding head is fixed to the bottom of the output shaft of the second motor 6. Controlling the first motor 3 to rotate forward or backward causes the lead screw 2 to rotate, thus allowing the movable seat 4 to move left and right. A knob is connected to the top of the oil tank 80, which is filled with lubricating fluid. Turning the knob allows for easy addition of lubricating fluid, which lubricates the lead screw 2 and the movable seat 4. A clamp is installed on the top of the base 11 for easy clamping of the workpiece.

[0026] When grinding is required, the workpiece is placed on the surface of the base 11 and clamped by the fixture. The cylinder 5 and motor 6 are activated, causing the grinding head to move downwards for grinding. To adjust the grinding position, motor 3 is controlled to rotate forward or backward, causing the lead screw 2 to rotate. This allows the moving seat 4 to move left or right, and the cylinder 5 to adjust its position. When the moving seat 4 is at its rightmost position, it contacts the push rod 83. The push rod 83 then moves the piston rod 81 to the right, compressing the spring 82. This pressure causes the ball 86 to disengage from the through hole 88, compressing the spring 85 and allowing the lubricant in the fixed frame 800 to enter the cavity 84. The lubricating fluid in cavity 84 enters the guide tube 805 and spray pipe 806 through through hole 2 89, and can be sprayed onto the surface of lead screw 2 for lubrication. When the moving seat 4 is not in contact with the push rod 83, spring 1 82 is released and piston rod 81 is reset. At this time, the pressure causes spring 2 85 to drive ball 1 86 to reset, and spring 3 803 is compressed, causing ball 2 802 to disengage from through hole 3 801, so that the lubricating fluid in oil tank 80 can enter the fixed frame 800. When the moving seat 4 reciprocates, the lubricating fluid can be sprayed onto the surface of lead screw 2 repeatedly, without the need for manual addition, improving efficiency and avoiding guide rail wear during long-term operation, thus improving equipment accuracy and service life.
