DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the technical means, creative features, achieving purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 and Figure 2 shown, a flattening processing device for machining includes a base 1. A flattening assembly 2 is fixedly installed on the upper right part of the base 1. A moving and adjusting assembly 3 is movably connected to the lower left part of the base 1. The top of the moving and adjusting assembly 3 is movably connected to a fixing assembly 4.

[0027] The leveling component 2 can level the surfaces of workpieces of different sizes through the grinder 26. The fixed workpiece can be moved to the left of the grinder 26 for processing through the moving and adjusting component 3. Since the workbench 35 can be rotated to any angle by the electric push rod 36, the grinder can act on different surfaces of the workpiece, improving the practicality of the device. Different-sized workpieces can be fixedly clamped through the fixing component 4. At the same time, the heights of the two fixing frames 47 can be adjusted relative to the workbench 35, enabling the two fixing frames 47 to be adjusted according to the actual size of the workpiece, thereby preventing the grinder 26 from colliding with the fixing frames 47 during operation.

[0028] As Figure 3 shown in the figure, the leveling component 2 includes a mounting frame 21. The lower end of the mounting frame 21 is fixedly installed at the upper right part of the base 1. The front part at the lower end of the top of the mounting frame 21 is rotatably connected to a lead screw 23 passing through the top of the mounting frame 21. A driving motor 22 is fixedly installed at the front part of the upper end of the mounting frame 21. The output end of the driving motor 22 is fixedly connected to the upper end of the lead screw 23. A moving frame 25 is threadedly connected to the outer wall of the lead screw 23. A grinder 26 is fixedly installed at the left bottom of the moving frame 25. A limiting rod 24 is fixedly installed at the rear part at the lower end of the top of the mounting frame 21. The rear inner wall of the moving frame 25 is slidably connected to the outer wall of the limiting rod 24.

[0029] The output end of the driving motor 22 can drive the lead screw 23 to rotate. The moving frame 25 drives the grinder 26 to move to a suitable position by being threadedly connected to the lead screw 23, enabling the grinder 26 to act on workpieces of different heights. During the movement of the moving frame 25, its rear part slides on the limiting rod 24, and the limiting rod 24 plays a limiting role in the movement of the moving frame 25. Among them, the grinder 26 is an existing mechanism, usually driven by a servo motor to drive a grinding wheel to rotate.

[0030] As Figure 4 shown in the figure, the moving and adjusting component 3 includes a motor 31. The rear end of the motor 31 is fixedly installed with a fixing frame. The upper end of the fixing frame is fixedly installed at the rear part of the lower left part of the base 1. The output end of the motor 31 is fixedly sleeved with a gear 32. A rack 33 is slidably connected to the rear part of the lower left part of the base 1. The outer surface of the gear 32 meshes with the lower side of the rack 33.

[0031] The output end of the motor 31 can drive the gear 32 to rotate, and the rack 33 moves by meshing with the gear 32.

[0032] As Figure 4 shown in the figure, a chute is opened at the upper left part of the base 1. A moving plate 34 is slidably connected to the inner wall of the chute. The lower left part of the moving plate 34 is fixedly connected to the front left part of the rack 33.

[0033] Through the movement of the rack 33, the rack 33 can drive the moving plate 34 to move in the chute, so that the moving plate 34 can drive the fixed workpiece to move to the left side of the grinder 26.

[0034] As Figure 4 and Figure 5 shown, a workbench 35 is rotatably connected to the upper right part of the upper end of the moving plate 34, an electric push rod 36 is rotatably connected to the upper left part of the upper end of the moving plate 34, and the output end of the electric push rod 36 is rotatably connected to the lower right part of the lower end of the workbench 35.

[0035] Through the output end of the electric push rod 36, it can drive the workbench 35 to rotate to a suitable angle, so that all surfaces of the workpiece fixed on the workbench 35 can be polished.

[0036] As Figure 5 and Figure 6 shown, the fixing assembly 4 includes a reverse double-threaded rod 41. An installation groove 42 is opened in the middle of the upper end of the workbench 35. The front and rear ends of the reverse double-threaded rod 41 are rotatably connected to the inner wall of the installation groove 42. The front end of the reverse double-threaded rod 41 penetrates through the front part of the workbench 35 and is fixedly installed with a handwheel 43. Moving blocks 44 are threadedly connected to the front and rear parts of the outer wall of the reverse double-threaded rod 41, and fixing plates 45 are fixedly installed at the upper ends of the two moving blocks 44.

[0037] By rotating the handwheel 43, the reverse double-threaded rod 41 rotates in the installation groove 42. The two moving blocks 44 approach or move away from each other by being threadedly connected to the reverse double-threaded rod 41. At the same time, the two moving blocks 44 drive the two fixing plates 45 to move respectively.

[0038] As Figure 6 shown, T-shaped strips 46 are fixedly installed on the left and right sides of the two fixing plates 45. Fixed frames 47 are slidably connected to the mutually remote sides of the four adjacent T-shaped strips 46. A plurality of linearly arranged adjusting holes 48 are opened on the mutually remote sides of the two fixing plates 45. Fixing rods 49 penetrating through the mutually remote sides of the two fixed frames 47 are slidably connected to the bottoms of the mutually remote sides of the two fixed frames 47. The opposite ends of the two fixing rods 49 are inserted into the inner walls of a plurality of adjacent adjusting holes 48.

[0039] By adjusting the two fixing rods 49, the two fixing rods 49 are inserted into different adjusting holes 48. In this way, the two fixed frames 47 can be slid to appropriate positions through the corresponding T-shaped strips 46, so that the height of the two fixed frames 47 from the workbench 35 can be adjusted, so that when the two fixed frames 47 clamp workpieces of different sizes, the grinder 26 will not collide with the two fixed frames 47 due to the low height of the workpiece.

[0040] As Figure 6As shown, on the outer walls of the two fixing rods 49 on the sides far away from each other, springs 410 are movably sleeved. The opposite ends of the two springs 410 are fixedly connected to the bottoms of the sides of the two fixing frames 47 far away from each other, and the ends of the two springs 410 far away from each other are fixedly connected to the sides of the outer walls of the two fixing rods 49 far away from each other.

[0041] When moving the two fixing rods 49, the corresponding springs 410 will be subjected to tensile forces. When the two fixing frames 47 are adjusted properly, release the two fixing rods 49, and the elastic restoring forces of the two springs 410 will drive the corresponding fixing rods 49 to reset, so that the two fixing rods 49 can be quickly inserted into different adjustment holes 48.

[0042] The working principle of the present utility model: The staff places the workpiece to be leveled and processed on the workbench 35. At this time, the workbench 35 is in a horizontal position. According to the actual height of the workpiece, pull the two fixing rods 49 to pull the two fixing rods 49 out of the corresponding adjustment holes 48 and stretch the springs 410. Slide the two fixing frames 47 up and down so that the heights of the two fixing frames 47 are always lower than the height of the workpiece. Then release the two fixing rods 49, and the elastic restoring forces of the two springs 410 drive the two fixing rods 49 to reset and insert into the new adjustment holes 48. Rotate the handwheel 43, the handwheel 43 drives the reverse double-threaded rod 41 to rotate, and the two moving blocks 44 drive the two fixing plates 45 to approach each other through being threadedly connected with the reverse double-threaded rod 41, so that the two fixing plates 45 drive the corresponding fixing frames 47 to approach each other to clamp and fix the workpiece.

[0043] Then start the motor 31, the output end of the motor 31 drives the gear 32 to rotate, and the rack 33 drives the moving plate 34 to move to a suitable position through meshing with the gear 32. Start the driving motor 22 and the grinder 26, the output end of the driving motor 22 drives the moving frame 25 to move, and the moving frame 25 drives the grinder 26 to contact the surface of the workpiece, so as to perform the leveling work on the surface of the workpiece.

[0044] When it is necessary to grind different surfaces of the workpiece subsequently, drive the moving plate 34 to move to the left, start the electric push rod 36, the output end of the electric push rod 36 drives the workbench 35 to rotate a certain angle, and the workbench 35 drives the workpiece to rotate to a position where the surface to be ground is parallel to the grinder 26, and then move the moving plate 34 to make the workpiece contact the grinder 26.
