During grinding, due to the uneven surface of the mechanical equipment, when using the current grinding device for grinding, only a single grinding can be performed on the high or low positions, and the high and low positions cannot be ground simultaneously, resulting in low grinding efficiency. Summary of the Utility Model

The first connecting plate is abutted against the bottom inside the box body through the tension of the spring, and a grinding disc is detachably connected to the lower end of the sleeve.

[0006] Preferably, the driving mechanism includes a transmission shaft rotatably connected to the box body and located above the partition, a first bevel gear connected to the upper end of the rotating shaft, a second bevel gear connected to the transmission shaft and meshing with the first bevel gear, and a motor installed at one end of the box body and drivingly connected to the transmission shaft.

[0007] Preferably, protective sleeves are arranged around the first connecting plate and the second connecting plate, the upper ends of the protective sleeves are connected to the partition, and the lower ends of the protective sleeves are connected to the bottom of the box body.

[0008] Preferably, a screw rod is connected to the lower end of the sleeve, a connecting head is connected to the upper end of the grinding disc, the connecting head is in threaded connection with the screw rod, screw holes are arranged on both the screw rod and the connecting head, and after the connecting head is in threaded connection with the screw rod, the two screw holes are aligned, and then the connecting head and the screw rod are fixed through the cooperation of bolts and the screw holes.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] Under the action of the spring, all the grinding discs are in the same plane and can grind mechanical equipment with a flat surface. When the surface of the mechanical equipment is uneven and has a height difference, the high part of the mechanical equipment squeezes the grinding disc, causing the sleeve to move upward and compress the spring, while the low part of the mechanical equipment does not squeeze the grinding disc. Therefore, some grinding discs will contact the low part, so that different grinding discs respectively contact the high part and the low part of the mechanical equipment. At this time, the driving mechanism drives the rotation of the rotating shaft. Since the rotating shaft is spline-connected to the sleeve, the rotation of the rotating shaft drives the rotation of the sleeve, thereby driving the grinding disc to rotate to grind the high part and the low part of the mechanical equipment at the same time for rust removal, improving the rust removal range and efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment 1

[0017] Please refer to Figure 1-2, a surface grinding and rust-removing device for mechanical equipment, including a box body 1. A partition 2 is connected inside the box body 1. A plurality of rotating shafts 4 are rotatably connected to the partition 2 through rotating bearings 3. A driving mechanism for driving all the rotating shafts 4 to rotate is provided above the partition 2 inside the box body 1. Specifically, the driving mechanism includes a transmission shaft 10 rotatably connected to the box body and located above the partition, a first bevel gear 11 connected to the upper end of the rotating shaft, a second bevel gear 12 connected to the transmission shaft and meshing with the first bevel gear, and a motor 13 installed at one end of the box body and drivingly connected to the transmission shaft. Starting the motor drives the transmission shaft to rotate, and through the cooperation of the second bevel gear and the first bevel gear, all the rotating shafts are driven to rotate together.

[0018] A plurality of openings matching the rotating shafts are provided at the bottom of the box body 1. A sleeve 5 is movably arranged in the openings, that is, the sleeve can move up and down in the openings. The rotating shaft 4 is spline-connected to the inner wall of the sleeve 5, so that the sleeve can move up and down along the rotating shaft, and the sleeve will also be driven to rotate when the rotating shaft rotates. A first connecting plate 6 is connected to the outer wall of the sleeve 5, a second connecting plate 7 is connected to the outer wall of the rotating shaft 4, and a spring 8 is connected between the first connecting plate 6 and the second connecting plate 7. The first connecting plate 6 is abutted against the bottom inside the box body 1 by the tension of the spring 8, and a grinding disc 9 is detachably connected to the lower end of the sleeve 5.

[0019] Specifically, a screw rod 15 is connected to the lower end of the sleeve 5, a connecting head 16 is connected to the upper end of the grinding disc 9, the connecting head 16 is threadedly connected to the screw rod 15, and screw holes are provided on both the screw rod 15 and the connecting head 16. After the connecting head 16 is threadedly connected to the screw rod 15, the two screw holes are aligned, and then the connecting head 16 and the screw rod 15 are fixed through the cooperation of a bolt 17 and the screw holes. When the grinding disc 9 is damaged, the bolt is removed and the grinding disc can be replaced.

[0020] A protective cover 14 is provided outside the first connecting plate 6 and the second connecting plate 7. The upper end of the protective cover 14 is connected to the partition 2, and the lower end of the protective cover 14 is connected to the bottom of the box body 1. The protective cover can protect the first connecting plate, the second connecting plate and the spring.

[0021] The working principle of this embodiment is as follows:

[0022] When the surface of the mechanical equipment is uneven and has a height difference, the high part of the mechanical equipment squeezes the grinding disc 9, causing the sleeve 5 to move upward and squeezing the spring 8 through the first connecting plate 6, while the low part of the mechanical equipment does not squeeze the grinding disc. Therefore, part of the grinding disc will contact the low part, so that different grinding discs respectively contact the high part and the low part of the mechanical equipment. At this time, all the rotating shafts 4 are driven to rotate simultaneously through the driving mechanism. Since the rotating shaft 4 is spline-connected to the sleeve 5, the rotation of the rotating shaft 4 drives the sleeve 5 to rotate, thereby driving the grinding disc 9 to rotate to simultaneously grind the high part and the low part of the mechanical equipment for rust removal, improving the rust removal range and rust removal efficiency.
