Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a grinding machine for machining. Background Technology

[0002] A grinding machine is a machine tool that uses abrasives to grind the surface of a workpiece. Grinding machines use a high-speed rotating grinding wheel or belt to grind the workpiece. The grinding wheel or belt consists of abrasive and a bonding agent, possessing high hardness and cutting power. During the grinding process, the abrasive cuts the workpiece surface, removing material to achieve the required dimensional accuracy and surface roughness.

[0003] However, existing belt grinders require separate operations on the flat and chamfered areas to complete the surface grinding process, and the poor fit between the belt and the workpiece greatly limits the grinding effect. Therefore, in view of the above-mentioned technical defects of the existing technology, a new grinding machine for machining is proposed to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a grinding machine for machining to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A grinding machine for machining includes a base plate, a fixed frame fixed on the base plate, a hydraulic cylinder fixed on the fixed frame, a lifting frame fixed to the telescopic end of the hydraulic cylinder, a clamping assembly mounted on the base plate, a workpiece mounted on the clamping assembly, a vertically arranged support frame fixed on the lifting frame, a horizontally arranged sleeve fixed to the bottom of the support frame, two horizontal frames slidably mounted on the sleeve, a rotating roller II rotatably mounted on each horizontal frame, a rotating roller I rotatably mounted on the support frame, a grinding belt being drivenly connected to the rotating roller II and rotating roller I, a motor for driving the rotating roller I to rotate is mounted on the lifting frame, an adjustment assembly for horizontally sliding adjustment of the rotating roller I is mounted on the lifting frame, a collection box is mounted on the horizontal frame, a dust collection assembly for cleaning the grinding belt is provided in the collection box, and a motor for driving the rotating roller I to rotate is fixed on the lifting frame.

Detailed Implementation

[0021] The technical solution of this utility model will be further described in detail below with reference to specific embodiments:

[0022] Example 1

[0023] Please see Figure 1-6 A grinding machine for machining includes a base plate 1, a fixed frame 2 fixed on the base plate 1, a hydraulic cylinder 3 fixed on the fixed frame 2, a lifting frame 5 fixed to the telescopic end of the hydraulic cylinder 3, a clamping assembly mounted on the base plate 1, a workpiece 7 mounted on the clamping assembly, a vertically arranged support frame 14 fixed on the lifting frame 5, a horizontally arranged sleeve 16 fixed to the bottom of the support frame 14, two horizontal frames 26 slidably mounted on the sleeve 16, a rotating roller II 11 rotatably mounted on each horizontal frame 26, a rotating roller I 10 rotatably mounted on the support frame 14, a grinding belt 4 being drivenly connected to the rotating roller II 11 and the rotating roller I 10, a motor 6 for driving the rotating roller I 10 to rotate mounted on the lifting frame 5, an adjustment assembly for horizontally sliding adjustment of the rotating roller I 10 mounted on the lifting frame 5, and a collection box 9 mounted on the horizontal frame 26, with a dust collection assembly for cleaning the grinding belt 4 inside the collection box 9.

[0024] The device clamps the workpiece 7 using a clamping assembly. The hydraulic cylinder 3 drives the lifting frame 5 and the support frame 14 to move downward, causing the rotating rollers I10 and II11 to move the grinding belt 4 downward as a whole. Finally, the working surface of the grinding belt 4 moves downward and contacts the upper surface of the workpiece 7. The motor 6 drives the rotating roller I10 to rotate, and the rotating roller I10 drives the grinding belt 4 to rotate, thus achieving surface grinding of the workpiece 7.

[0025] The adjustment assembly of this device includes a sliding sleeve 15 that is vertically slidably mounted on the lifting frame 5. A connecting rod 13 is hinged between the sliding sleeve 15 and the horizontal frame 26. A connecting spring 17 is hinged between the horizontal frame 26 and the sleeve 16. A locking stud II 18 that abuts against the lifting frame 5 is threaded onto the sliding sleeve 15.

[0026] With the above settings, the sliding sleeve 15 is adjusted to move vertically relative to the lifting frame 5, so that the sliding sleeve 15 drives the horizontal frame 26 to slide relative to the sleeve 16 through the connecting rod 13. At this time, the rotating roller II 11 moves to ensure that the grinding belt 4 is in contact with the chamfer position of the workpiece 7, and ensures that the workpiece 7 is fully ground.

[0027] The clamping assembly of this device includes a spiral frame 8 fixed on the base plate 1, a clamping plate 24 slidably mounted on the spiral frame 8, and a locking stud I12 threadedly connected to the spiral frame 8 to abut against the clamping plate 24. A traction spring 25 is fixed between the clamping plate 24 and the spiral frame 8.

[0028] The workpiece 7 is placed inside the frame 8. By screwing multiple locking studs I12 into the frame 8, the clamping plate 24 is pushed towards the workpiece 7 by the locking studs I12, thus clamping and fixing the workpiece 7. This ensures that the workpiece 7 is stable during the grinding process and guarantees a stable grinding effect.

[0029] Example 2

[0030] Please see Figure 1-6 Based on Embodiment 1, the dust collection component of this device includes a rotating shaft 22 rotatably installed in the collection box 9. A belt pulley mechanism 19 is connected between the rotating shaft 22 and the rotating roller II11. Several brush plates 20 located in the collection box 9 are fixed on the side wall of the rotating shaft 22. The brush plates 20 are in contact with the outer wall of the abrasive belt 4.

[0031] During the rotation of the rotating roller II11, the abrasive belt 4 on the rotating roller II11 moves relative to the brush plate 20. At the same time, the rotating roller II11 drives the rotating shaft 22 to rotate through the belt pulley mechanism 19. That is, the rotating shaft 22 can drive the brush plate 20 to rotate and clean the working surface of the abrasive belt 4, so as to sweep the debris and dust on the abrasive belt 4 into the collection box 9, avoiding the debris and dust from flying, and also avoiding the debris and dust remaining on the abrasive belt 4 and affecting its grinding effect on the workpiece 7.

[0032] Furthermore, the dust collection assembly of this device also includes several axial flow fan blades 23 fixed to the side wall of the rotating shaft 22. The end of the collection box 9 is connected to a guide pipe 21, and the axial flow fan blades 23 are located inside the guide pipe 21. When the rotating shaft 22 rotates, the rotating shaft 22 drives the axial flow fan blades 23 to rotate. At this time, the axial flow fan blades 23 will transport the debris and dust brushed on the brush plate 20. The dust and debris are discharged into the external storage device along the guide pipe 21, thus avoiding the accumulation of debris and dust in the collection box 9.

[0033] In summary, this utility model has the effect of fully and efficiently grinding the workpiece 7, and is flexible and quick to adjust. The hydraulic cylinder 3 can synchronously adjust the vertical height of the lifting frame 5 and the support frame 14, so that the grinding belt 4 can come into contact with the surface of the workpiece 7 to be ground. The adjustment component can move the position of the rotating roller II11, so that the rotating roller II11 pulls the grinding belt 4 to move and come into contact with the chamfer of the workpiece 7, thus realizing the full grinding effect of the workpiece 7.
