[0002] A grinding machine is a machine tool that uses grinding wheels to grind workpieces to obtain the required shape, size and precision machined surface. Grinding machines are divided into ordinary external cylindrical grinding machines, traditional internal cylindrical grinding machines, coordinate grinding machines, centerless grinding machines, etc. The processing action of grinding machines is grinding. Grinding work occupies a primary position in machining. The sharpening of cutting tools and the precision manufacturing of mechanical parts both depend on grinding work. Grinding work is also a part of precision machining.

[0003] During the grinding process, debris is inevitably generated. Due to the high-speed rotation of the grinding wheel, this debris can easily fly everywhere, causing injury to nearby workers. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a precision grinding machine for machining precision parts, which solves the problem that the grinding debris generated by the high-speed rotation of the grinding wheel is easily scattered everywhere, thus easily causing injury to the surrounding workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision grinding machine for machining precision parts, comprising a base, fixed rods connected to both sides of the base, a baffle slidably mounted on the base via the fixed rods, a vertical plate connected above the base, a fixture fixing table fixedly mounted on the base, a drive motor fixedly mounted on one side of the base, a rotating rod connected to the output shaft of the drive motor, main bevel gears connected to both ends of the rotating rod, a secondary bevel gear meshing with the main bevel gear, a rotating rod connected to the secondary bevel gear, and a hydraulic push rod fixedly mounted on the vertical plate;

[0006] The movable end of the hydraulic push rod is connected to a movable column, a slotted plate is connected to the movable column, sliding sleeves are connected to both sides of the slotted plate, a working motor is fixedly installed on one side of the slotted plate, a lead screw is connected to the output shaft of the working motor, a moving block is threadedly installed on the lead screw, a mounting frame is connected below the moving block, a rotating shaft is rotatably connected to the mounting frame, and a grinding roller is installed on the rotating shaft.

[0007] As a further embodiment of this utility model: a drive motor is fixedly installed above the mounting bracket, a main synchronous pulley is installed on the output shaft of the drive motor, one end of the rotating shaft passes through the mounting bracket and is connected to a secondary synchronous pulley, and a toothed belt is installed on both the main synchronous pulley and the secondary synchronous pulley.

[0008] As a further embodiment of this utility model: the base is connected to guide rods on both sides of the upright plate, and springs are sleeved on the guide rods; the movable column is slidably connected to the upright plate.

[0009] As a further embodiment of this utility model: both the rotating rod and the rotatable rod are rotatably connected to the base, the part of the rotatable rod extending out of the base is provided with a thread, the lead screw is rotatably connected inside the slotted plate, and the moving block is in contact with the inner wall of the slotted plate.

[0010] As a further embodiment of this utility model: a threaded sleeve is connected to the baffle, and multiple sliding holes are provided on the baffle. The sliding holes are slidably connected to the fixed rod, and the threaded sleeve is threadedly engaged with the rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This precision grinding machine for machining precision parts is equipped with a drive motor, rotating rod, main bevel gear, secondary bevel gear, rotating rod, threaded sleeve, fixed rod, and sliding hole. The operator starts the drive motor, which drives the rotating rod to rotate. The meshing of the main bevel gear and secondary bevel gear synchronously drives the two rotating rods to rotate. Due to the threaded engagement between the threaded sleeve and the rotating rod, the baffle can move up and down along the rotating rod. At this time, the baffle slides on the fixed rod through the sliding hole, thereby adjusting the height of the baffle and causing the baffle to surround the grinding area, thus preventing debris from flying around and causing injury to the operator.

[0014] 2. This precision grinding machine for machining precision parts is equipped with a hydraulic push rod, a slotting plate, a lead screw, a moving block, a rotating shaft, a grinding roller, a guide rod, and a spring. By starting the working motor, the lead screw is rotated, causing the moving block to move within the slotting plate and drive the mounting frame. Simultaneously, the transmission motor rotates the main synchronous pulley. The main synchronous pulley, the auxiliary synchronous pulley, and the toothed belt work together to drive the rotating shaft, causing the grinding roller to rotate. At this time, the hydraulic push rod pulls the movable column, causing the slotting plate and the grinding roller to move downward as a whole, thus contacting the workpiece to complete the grinding. Meanwhile, the sliding sleeve slides on the guide rod and stretches the spring, thereby guiding the movement and making it more stable. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a precision grinding machine for machining precision parts, including a base 1, with fixed rods 2 connected to both sides of the base 1, and a baffle 3 slidably mounted on the base 1 via the fixed rods 2. A threaded sleeve 27 is connected to the baffle 3, and multiple sliding holes 28 are provided on the baffle 3. The sliding holes 28 are slidably connected to the fixed rods 2, and the threaded sleeve 27 is threadedly engaged with the rotating rod 10. The fixed rods 2 limit and guide the baffle 3, so that the baffle 3 can move up and down smoothly when the rotating rod 10 rotates.

[0022] A vertical plate 4 is connected above the base 1. Guide rods 25 are connected to both sides of the base 1 on the vertical plate 4. Springs 26 are sleeved on the guide rods 25. The movable column 12 is slidably connected to the vertical plate 4. The movable column 12 is driven to slide on the vertical plate 4 by the hydraulic push rod 11, thereby changing the height of the slotted plate 13, and thus adjusting the working height of the grinding roller 20, so that the grinding roller 20 contacts the surface of the workpiece for grinding.

[0023] A clamping platform 5 is fixedly installed on the base 1. A drive motor 6 is fixedly installed on one side of the base 1. A rotating rod 7 is connected to the output shaft of the drive motor 6. A main bevel gear 8 is connected to both ends of the rotating rod 7. A secondary bevel gear 9 is meshed with the main bevel gear 8. A rotating rod 10 is connected to the secondary bevel gear 9. Both the rotating rod 7 and the rotating rod 10 are rotatably connected to the base 1. The part of the rotating rod 10 that extends out of the base 1 is threaded. A lead screw 16 is rotatably connected inside the slotted plate 13. A moving block 17 contacts the inner wall of the slotted plate 13. Through the contact between the moving block 17 and the inner wall of the slotted plate 13, the slotted plate 13 can restrict the moving block 17 and prevent the moving block 17 from rotating on the lead screw 16, thereby making the moving block 17 move smoothly.

[0024] A hydraulic push rod 11 is fixedly installed on the upright plate 4. The movable end of the hydraulic push rod 11 is connected to a movable column 12. A slotted plate 13 is connected to the movable column 12. Sliding sleeves 14 are connected to both sides of the slotted plate 13. The sliding sleeves 14 are slidably connected to the guide rod 25. One end of the spring 26 is connected to the top of the guide rod 25, and the other end of the spring 26 is connected to the sliding sleeve 14. When the slotted plate 13 moves vertically, the sliding sleeve 14 will slide synchronously along the guide rod 25, thereby guiding and limiting the slotted plate 13 through the guide rod 25.

[0025] A working motor 15 is fixedly installed on one side of the slotted plate 13. The output shaft of the working motor 15 is connected to a lead screw 16. A moving block 17 is threadedly installed on the lead screw 16. A mounting frame 18 is connected below the moving block 17. A rotating shaft 19 is rotatably connected to the mounting frame 18. A grinding roller 20 is installed on the rotating shaft 19. A drive motor 21 is fixedly installed above the mounting frame 18. A main synchronous pulley 22 is installed on the output shaft of the drive motor 21. One end of the rotating shaft 19 passes through the mounting frame 18 and is connected to a secondary synchronous pulley 23. A toothed belt 24 is installed on both the main synchronous pulley 22 and the secondary synchronous pulley 23. Through the cooperation between the main synchronous pulley 22, the secondary synchronous pulley 23 and the toothed belt 24, the drive motor 21 can drive the grinding roller 20 to rotate, thereby grinding the workpiece.

[0026] The working principle of this utility model is as follows:

[0027] The working motor 15 rotates the lead screw 16, causing the moving block 17 to move along the lead screw 16 within the slotted plate 13, thereby adjusting the horizontal position of the grinding roller 20. The drive motor 21 rotates the main synchronous wheel 22, and the cooperation between the main synchronous wheel 22, the auxiliary synchronous wheel 23 and the toothed belt 24 drives the rotating shaft 19, causing the grinding roller 20 to rotate. The hydraulic push rod 11 can pull the movable column 12, causing the slotted plate 13 and the grinding roller 20 to move down as a whole, thereby adjusting the vertical position of the grinding roller 20 and causing the grinding roller 20 to contact the workpiece to complete the grinding. The drive motor 6 is started to drive the rotating rod 7 to rotate, and the meshing of the main bevel gear 8 and the auxiliary bevel gear 9 synchronously drives the two rotating rods 10 to rotate, so that the baffle 3 can move up and down along the rotating rod 10 through the threaded sleeve 27, thereby adjusting the height of the baffle 3 and causing the baffle 3 to surround the grinding area to prevent debris from flying everywhere.
