Description
Technical Field
[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for the edges and corners of a warehouse steel pallet. Background Technology
[0002] Steel pallets are an indispensable auxiliary equipment for warehousing and transportation in modern industry. In the process of producing steel pallets, angle grinders are often used to grind the edges and corners of the pallets. Angle grinders mainly use high-speed rotating grinding wheels and rubber grinding wheels to grind, remove rust, and polish metal components.
[0003] When using an angle grinder to grind the edges and corners of a steel pallet, the grinding wheel rotates at high speed and rubs against the edges and corners of the pallet. However, after the angle grinder is powered off, the grinding wheel will not rotate at high speed, but it can still rotate. If the grinding wheel comes into contact with other items, especially fabrics or wires, while carrying the angle grinder, it can easily become entangled in the grinding wheel, causing wear and tear on the items, and in severe cases, even damage. Utility Model Content
[0004] This utility model proposes a grinding device for the edges and corners of a storage steel pallet to solve the problem that when carrying an angle grinder, the grinding wheel can easily become entangled in other items, especially fabrics and wires, causing wear and tear on the items, or even damage.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grinding device for processing the edges and corners of a storage steel pallet, comprising a machine body, a casing, a protective plate, and a grinding wheel. The casing is installed at one end of the machine body, the protective plate is fixedly installed on one side of the casing by bolts, the grinding wheel is disposed inside the protective plate and rotatably installed on one side of the casing, and a fixing device is provided on the outer surface of the protective plate. The fixing device clamps and fixes the grinding wheel by two clamping plates.
[0006] The effect achieved by the above components is that by setting two clamping plates, the grinding wheel can be clamped and fixed, which helps to prevent the grinding wheel from rotating and getting entangled in other items, thus preventing damage to the items.
[0007] Preferably, the fixing device includes two clamping plates symmetrically arranged inside the protective plate, the grinding wheel is arranged between the two clamping plates, auxiliary grooves are symmetrically opened on the outer surface of the protective plate, the outer surfaces of the clamping plates are slidably mounted on the inner wall of the auxiliary grooves, one end of each clamping plate passes through the inner wall of the auxiliary groove and is threadedly connected to a threaded rod, the two threaded rods have the same thread size and opposite direction, the two threaded rods are fixedly connected at their close ends, and the outer surfaces of the threaded rods are rotatably connected to connecting blocks through bearings, one side of each connecting block is symmetrically fixedly connected to the outer surface of the protective plate.
[0008] The effect achieved by the above components is as follows: by setting two clamping plates, under the action of two threaded rods, rotating the two threaded rods will cause one clamping plate to move in opposite directions until the two clamping plates completely clamp the grinding wheel, thus the two clamping plates can fix the grinding wheel.
[0009] Preferably, rubber blocks are bonded to the sides of the two clamping plates that are close to each other. One side of the rubber block is adapted to the outer surface of the grinding wheel and has several grooves evenly provided.
[0010] The effect achieved by the above components is that by setting the rubber blocks with grooves, the friction on the clamping side of the clamping plates can be increased, making the clamping of the grinding wheel by the two clamping plates more stable.
[0011] Preferably, the same sponge block is adhered to one side of the inner wall of the auxiliary groove and one side of the rubber block, and the top and bottom of the sponge block abut against the inner wall of the auxiliary groove.
[0012] The effect achieved by the above components is as follows: by setting up the sponge block, the excellent deformation of the sponge block is used to seal the gap between the rubber block and the auxiliary groove. Even if the rubber block moves, the sponge block can still play a good sealing role, which helps to prevent metal chips generated during the grinding process from escaping from the gap between the rubber block and the auxiliary groove and affecting the normal operation of the grinding personnel.
[0013] Preferably, an L-shaped plate is fixedly connected to the top of the clamping plate, one side of the L-shaped plate abuts against one side of the protective plate, and a scale groove is symmetrically opened on one side of the protective plate.
[0014] The effect achieved by the above components is as follows: by setting L-shaped plates and graduated grooves, the position of the graduated grooves corresponds to the edge position of the grinding wheel. When the two L-shaped plates are outside the two graduated grooves, it indicates that the clamping plate and the rubber block have moved away from the grinding wheel. Correspondingly, when the two L-shaped plates are both inside the two graduated grooves, it indicates that the rubber block is in contact with the outer surface of the grinding wheel. Thus, it can be seen from the back of the grinding wheel whether the grinding wheel is fixed, which makes it easier to use the angle grinder. In addition, red paint can be added to the inside of the graduated grooves to further serve as a reminder.
[0015] Preferably, each of the two threaded rods has an operating block fixedly connected to one of its far ends, and the outer surface of the operating block is provided with a protrusion.
[0016] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.
[0017] Preferably, the fastening assembly includes an auxiliary block, one end of which is fixedly mounted on the outer surface of the protective plate, and one end of each of the two threaded rods is rotatably mounted on the inner wall of the auxiliary block via bearings. Nuts are threaded onto the outer surface of each threaded rod, and the nuts are disposed between the auxiliary block and the clamping plate.
[0018] The effect achieved by the above components is as follows: by rotating the two nuts so that one side of the nuts abuts against one side of the auxiliary block, the two nuts can fix the two threaded rods and the auxiliary block, thereby preventing the two threaded rods from rotating and helping to prevent the clamp from shifting due to loosening of the threaded rods.
[0019] Preferably, a rubber pad is fixedly connected to one side of the nut, and the outer surface of the threaded rod is slidably inserted into the inner wall of the rubber pad.
[0020] The effect achieved by the above-mentioned components is that by setting the rubber pad, the friction on one side of the nut can be increased, which helps to prevent the nut from loosening.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting two clamping plates, under the action of two threaded rods, rotating the two threaded rods will cause one clamping plate to move in opposite directions until the two clamping plates completely clamp the grinding wheel. The two clamping plates can fix the grinding wheel, which helps to prevent other items from getting tangled on the grinding wheel and causing damage during the carrying of the angle grinder, making the angle grinder easier to carry.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a grinding device for the edges and corners of a warehouse steel pallet, including a body 1, a casing 2, a protective plate 3, and a grinding wheel 4. The casing 2 is installed at one end of the body 1, and the protective plate 3 is fixedly installed on one side of the casing 2 by bolts. The grinding wheel 4 is disposed inside the protective plate 3 and rotatably mounted on one side of the casing 2. A brushless motor and a reducer are disposed inside the casing 2. The output end of the brushless motor is connected to the grinding wheel 4 through the reducer, enabling the brushless motor to drive the grinding wheel 4 to rotate at high speed. A fixing device 5 is provided on the outer surface of the protective plate 3. The fixing device 5 clamps and fixes the grinding wheel 4 by two clamping plates 51. The fixing device 5 includes two clamping plates 51, which are symmetrically arranged inside the protective plate 3, and the grinding wheel 4 is disposed between the two clamping plates 51. The outer surface of the protective plate 3 is symmetrically provided with auxiliary grooves 52. The outer surface of the clamping plate 51 is slidably installed on the inner wall of the auxiliary groove 52. One end of each clamping plate 51 passes through the inner wall of the auxiliary groove 52 and is threadedly connected to a threaded rod 53. The threads of the two threaded rods 53 are the same size and opposite in direction. The ends of the two threaded rods 53 that are close to each other are fixedly connected. The outer surface of the threaded rod 53 is rotatably connected to a connecting block 54 through a bearing. One side of the two connecting blocks 54 is symmetrically fixedly connected to the outer surface of the protective plate 3. By setting two clamping plates 51, under the action of the two threaded rods 53, rotating the two threaded rods 53 will drive one clamping plate 51 to move towards each other until the two clamping plates 51 completely clamp the grinding wheel 4. Then the two clamping plates 51 can fix the grinding wheel 4.
[0029] Reference Figure 2 and Figure 3 As shown, rubber blocks 55 are bonded to the sides of the two clamping plates 51 that are close to each other. One side of the rubber block 55 is adapted to the outer surface of the grinding wheel 4 and has several grooves evenly provided. By setting the rubber block 55 with grooves, the friction of the clamping side of the clamping plate 51 can be increased, making the clamping of the grinding wheel 4 by the two clamping plates 51 more stable.
[0030] Reference Figure 2 and Figure 3As shown, a sponge block 56 is bonded to one side of the inner wall of the auxiliary groove 52 and one side of the rubber block 55. The top and bottom of the sponge block 56 abut against the inner wall of the auxiliary groove 52. By setting the sponge block 56, the excellent deformation of the sponge block 56 can seal the gap between the rubber block 55 and the auxiliary groove 52. Even if the rubber block 55 moves, the sponge block 56 can still play a good sealing role, which helps to prevent metal chips generated during the grinding process from escaping from the gap between the rubber block 55 and the auxiliary groove 52 and affecting the normal operation of the grinding personnel.
[0031] Reference Figures 2-4 As shown, an L-shaped plate 57 is fixedly connected to the top of the clamping plate 51. One side of the L-shaped plate 57 abuts against one side of the protective plate 3. A scale groove 58 is symmetrically provided on one side of the protective plate 3. By setting the L-shaped plate 57 and the scale groove 58, the position of the scale groove 58 corresponds to the edge position of the grinding wheel 4. When both L-shaped plates 57 are outside the two scale grooves 58, it indicates that the clamping plate 51 and the rubber block 55 have moved away from the grinding wheel 4. Conversely, when both L-shaped plates 57 are within the two scale grooves 58, it indicates that the rubber block 55 is abutting against the outer surface of the grinding wheel 4. The back of the grinding wheel 4 shows whether it is fixed, making it easier to use the angle grinder. Red paint can also be added to the inside of the scale groove 58 to further serve as a reminder. Each of the two threaded rods 53 has an operating block 59 fixedly connected to its far end. The outer surface of the operating block 59 has protrusions. By setting the operating block 59, rotating the operating block 59 can drive the threaded rod 53 to rotate. At the same time, the protrusions on the outer surface of the operating block 59 can effectively increase the friction of the outer surface of the operating block 59, which has an anti-slip function when rotating the operating block 59.
[0032] Reference Figure 2 and Figure 3 As shown, the fastening assembly 6 includes an auxiliary block 61. One end of the auxiliary block 61 is fixedly installed on the outer surface of the protective plate 3. One end of each of the two threaded rods 53 is rotatably installed on the inner wall of the auxiliary block 61 via bearings. Nuts 62 are threadedly connected to the outer surface of the threaded rods 53. The nuts 62 are positioned between the auxiliary block 61 and the clamping plate 51. By rotating the two nuts 62, one side of the nuts 62 abuts against one side of the auxiliary block 61, thus fixing the two threaded rods 53 to the auxiliary block 61. This prevents the two threaded rods 53 from rotating, which helps to prevent the clamping plate 51 from shifting due to the loosening of the threaded rods 53. A rubber pad 63 is fixedly connected to one side of the nut 62. The outer surface of the threaded rod 53 is slidably inserted into the inner wall of the rubber pad 63. By setting the rubber pad 63, the friction on one side of the nut 62 can be increased, which helps to prevent the nut 62 from loosening.
[0033] Working principle: Rotating the operating block 59 drives the two threaded rods 53 to rotate. Each threaded rod 53 drives a clamping plate 51 to move towards each other on the inner wall of the auxiliary groove 52 until the rubber blocks 55 on one side of the two clamping plates 51 completely clamp the grinding wheel 4. The two clamping plates 51 then fix the grinding wheel 4. Rotating the two nuts 62 causes the rubber pads 63 on one side of the nuts 62 to abut against one side of the auxiliary block 61. The two nuts 62 then fix the two threaded rods 53 to the auxiliary block 61, preventing the threaded rods 53 from rotating. This helps prevent the clamping plates 51 from shifting due to loosening of the threaded rods 53, and further helps prevent the grinding wheel 4 from rotating and becoming entangled in other objects. If the product is damaged, and the sponge block 56 keeps sealing the gap between the rubber block 55 and the auxiliary groove 52 during the movement of the clamping plate 51, it helps to prevent metal chips generated during the grinding process from escaping from the gap between the rubber block 55 and the auxiliary groove 52 and affecting the normal operation of the grinding personnel. It should be noted that the position of the scale groove 58 corresponds to the edge position of the grinding wheel 4. When the two L-shaped plates 57 are outside the two scale grooves 58, it means that the clamping plate 51 and the rubber block 55 have moved away from the grinding wheel 4. Correspondingly, when the two L-shaped plates 57 are both inside the two scale grooves 58, it means that the rubber block 55 is abutting against the outer surface of the grinding wheel 4. Thus, it can be seen from the back of the grinding wheel 4 whether the grinding wheel 4 is fixed.
