Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of grinding wheels for grinding machines, in particular to a disassembly and assembly device for grinding wheels. Background Art

[0002] A grinder is a machine tool that grinds the surface of a workpiece. Most grinders use high-speed rotating grinding wheels to grind and polish the workpiece. Since the grinding wheel is frequently used and the grinding process itself causes wear and consumption, there is a high demand for regular replacement of the grinding wheel. When the wear reaches a certain level, a new grinding wheel needs to be replaced. On the other hand, different types of workpieces also require the replacement of corresponding matching grinding wheels.

[0003] At present, the traditional way to replace the grinding wheel is through manual operation. That is, at least two people are required to manually carry the grinding wheel to the corresponding installation position of the grinder, and then lift the grinding wheel together to align it with the installation hole of the grinding wheel. The above process has the risk of collision and damage to the grinding wheel surface, and requires more manpower and time. Especially for some large grinders, replacing large-sized grinding wheels is more time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to solve the technical problem that the traditional manual disassembly and assembly of the grinding wheel is time-consuming and labor-intensive. The utility model provides a disassembly and assembly device for the grinding wheel, which can semi-automatically realize the disassembly and assembly of the grinding wheel, effectively improve the disassembly and assembly efficiency, and save time and labor costs.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a disassembly and assembly device for a grinding wheel, comprising:

[0006] Disassemble the main body;

[0007] A support portion, disposed at one end of the disassembly body, the support portion being used to be detachably connected to the grinding wheel, the support portion being provided with a disassembly hole group, the disassembly hole group being used to accommodate a disassembly component;

[0008] The connecting part is arranged at the other end of the disassembly and assembly main body, and the connecting part is provided with a plurality of first connecting holes, and any one of the plurality of first connecting holes is used for connecting with an external lifting ring.

[0009] By adopting the above technical solution, the disassembly and assembly device of the embodiment of the present application can be used to disassemble and install the grinding wheel of the grinding machine.

[0010] On the one hand, the connection portion provided at one end of the disassembly and assembly main body includes a plurality of first connection holes, any one of which can be connected to an external lifting ring, and at the same time, the support portion provided at the other end of the disassembly and assembly main body can cooperate with the disassembly and assembly component contained therein to be detachably connected to the grinding wheel, and then the external lifting ring is controlled to achieve the installation or removal of the grinding wheel. In other words, the disassembly and assembly device of the embodiment of the present application can switch between a first state (e.g., an unused state or a used state) and a second state (e.g., a used state). In the first state, the disassembly and assembly component of the support portion is accommodated in the disassembly and assembly hole group, and the plurality of first connection holes of the connection portion are separated from the external lifting ring. In the second state, the disassembly and assembly component of the support portion is separated from the disassembly and assembly hole group, and the disassembly and assembly component can cooperate with the support portion to be connected to the grinding wheel, and any one of the plurality of first connection holes of the connection portion is connected to the external lifting ring.

[0011] Specifically, for example, when the old grinding wheel needs to be replaced, first, the fixing parts of the old grinding wheel are removed, and then the disassembly assembly stored in the disassembly hole group of the support part is taken out, and the old grinding wheel is pushed out of the grinder through the disassembly assembly. Then the connecting part is connected to the external lifting ring, and the lifting ring is controlled to move to adjust the installation position, so that the supporting part is aligned with the corresponding hole position of the old grinding wheel, and then the supporting part and the old grinding wheel are connected through the disassembly assembly. Finally, the old grinding wheel connected to the supporting part is removed through the lifting ring.

[0012] At the same time, when a new grinding wheel needs to be installed, the support part is aligned with the corresponding hole position of the new grinding wheel by controlling the lifting ring, and the support part and the new grinding wheel are connected by the disassembly assembly, and then the new grinding wheel is lifted and moved to the installation position of the grinder. Then the new grinding wheel is pushed into the installation position of the grinder through the disassembly assembly, and the fixing parts of the new grinding wheel are locked. Then the disassembly assembly is taken out, and the support part is separated from the new grinding wheel, and the installation of the new grinding wheel is completed. Finally, the disassembly assembly is stored in the corresponding hole position of the disassembly hole group for the next use.

[0013] On the other hand, the connecting part of the disassembly and assembly device is provided with a plurality of first connecting holes, any one of which can be used to connect with an external lifting ring. That is to say, under different working conditions, the connection position with the external lifting ring can be adjusted arbitrarily so that the disassembly and assembly body is perpendicular to the ground, and the supporting part provided at the other end of the disassembly and assembly body can maintain balance, thereby ensuring that the grinding wheel connected to the supporting part will not tilt during installation, disassembly and transportation, thereby improving the disassembly and assembly efficiency.

[0014] On the other hand, the disassembly and assembly device of the embodiment of the present application can semi-automatically realize the disassembly and assembly of the grinding wheel, effectively improving the disassembly and assembly efficiency, saving time and labor costs. At the same time, it also greatly reduces the risk of collision and damage to the surface of the grinding wheel. In addition, the disassembly and assembly device of the embodiment of the present application is particularly suitable for the disassembly and assembly of grinding wheels with larger sizes in large grinders.

[0015] According to another specific embodiment of the present invention, the support portion is U-shaped.

[0016] By adopting the above technical solution, the support part is designed as a U-shaped structure, which can better adapt to the circular grinding wheel on the one hand, and on the other hand, it is convenient to connect with the disassembly and assembly main body to be more balanced and symmetrical, and has better aesthetics.

[0017] According to another specific embodiment of the utility model, the disassembly and assembly assembly includes a plurality of guide rods, a plurality of top screws and a plurality of screws.

[0018] According to another specific embodiment of the present utility model, the disassembly and assembly hole group includes a plurality of first accommodating holes, a plurality of second accommodating holes and a plurality of third accommodating holes that are spaced apart from each other, the plurality of guide rods in the disassembly and assembly assembly are used to be accommodated in the corresponding plurality of first accommodating holes, the plurality of top screws in the disassembly and assembly assembly are used to be accommodated in the corresponding plurality of second accommodating holes, and the plurality of screws in the disassembly and assembly assembly are used to be accommodated in the corresponding plurality of third accommodating holes.

[0019] According to another specific embodiment of the present invention, along the circumference of the support portion, the plurality of first accommodating holes, the plurality of second accommodating holes, and the plurality of third accommodating holes are respectively symmetrically arranged.

[0020] According to another specific embodiment of the present invention, the support portion further includes a plurality of second connection holes.

[0021] According to another specific embodiment of the present invention, the connecting portion is L-shaped.

[0022] By adopting the above technical solution, the support part is designed as an L-shaped structure, which can facilitate the connection of the external lifting ring to any first connecting hole of the support part. At the same time, it is also convenient to connect the support part with the disassembly and assembly main body, so that when the support part is connected to the lifting ring, the disassembly and assembly main body can be as vertical as possible to the ground without tilting.

[0023] According to another specific implementation of the present utility model, the supporting portion, the connecting portion and the detachable body are integrally formed. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] refer to Figure 1 and Figure 2 , Figure 1 A perspective view of the disassembly and assembly device 1 is shown exemplarily; Figure 2 The top view of the disassembly and assembly device 1 is shown exemplarily. The embodiment of the present application provides a disassembly and assembly device 1 for a grinding wheel, and the disassembly and assembly device 1 includes a disassembly and assembly body 10, a support portion 20, and a connecting portion 30. Exemplarily, the disassembly and assembly body 10, the support portion 20, and the connecting portion 30 are integrally formed, but the embodiment of the present application does not specifically limit this.

[0036] It can be seen that the disassembly body 10 is arranged along the first direction (eg Figure 1 The support portion 20 is disposed at one end of the disassembly body 10 (eg, Figure 1 and Figure 2 The connecting portion 30 is disposed at the other end of the disassembly body 10 (as shown in the direction a in FIG. Figure 1 and Figure 2 b direction).

[0037] Among them, reference Figure 3 , Figure 3 The following is an exemplary diagram showing an application scenario of the support portion 20 of the disassembly and assembly device 1. Figure 3 As shown, the disassembly and assembly device 1 of the embodiment of the present application can be applied to the installation field of a grinder 2 (such as a CNC grinder). Specifically, the grinder 2 includes a grinding wheel 3 for grinding. In actual application, the grinding wheel 3 has high wear requirements or service life requirements. When the wear reaches a certain level, it is necessary to replace the new grinding wheel 3. At the same time, if the grinding wheel 3 is out of its effective period or has abnormal conditions such as local cracks, it also needs to be replaced. In other words, the grinding wheel 3, as an important component of the grinder 2, is also a consumable that is relatively easy to consume, so it needs to be replaced regularly.

[0038] refer to Figure 3 Combined with Figure 5It can be seen that the support portion 20 of the disassembly and assembly device 1 of the embodiment of the present application is connected to the grinding wheel 3 in a detachable manner, and the support portion 20 is provided with a disassembly and assembly hole group 200, and the disassembly and assembly hole group 200 is used to accommodate the disassembly and assembly component 40.

[0039] Exemplarily, the support portion 20 is U-shaped. Designing the support portion 20 as a U-shaped structure can better fit the circular grinding wheel 3 on the one hand, and on the other hand, it is also convenient for the connection with the disassembly and assembly main body 10 to be more balanced and symmetrical, and has better aesthetics.

[0040] Further, refer to Figure 1 and Figure 4 , Figure 4 The side view of the disassembly and assembly device 1 is shown as an example. Figure 4 As shown, the connection portion 30 of the disassembly and assembly device 1 of the present embodiment is provided with four first connection holes 300, such as Figure 1 As shown, any one of the four first connection holes 300 is used to connect with the external lifting ring 4, and the external lifting ring 4 can be matched with the hook of the external electric cantilever crane, although in the embodiment of the present application Figure 1 In the figure, only the lifting ring 4 is shown, but it can be understood that the cantilever crane is a mechanical device for lifting and carrying objects, and the lifting ring 4 is a component for connecting the cantilever crane hook.

[0041] refer to Figures 1 to 4 , using the above technical solution, the disassembly and assembly device 1 of the embodiment of the present application can be used for disassembly and installation of the grinding wheel 3 of a grinder 2 (such as a CNC grinder).

[0042] On the one hand, the connection portion provided at one end of the disassembly and assembly main body 10 includes a plurality of first connection holes 300, any one of which can be connected to an external lifting ring 4. At the same time, the support portion 20 provided at the other end of the disassembly and assembly main body 10 can cooperate with the disassembly and assembly component 40 accommodated therein to be detachably connected to the grinding wheel 3, and then the installation or disassembly of the grinding wheel 3 can be achieved by controlling the external lifting ring 4.

[0043] Specifically, for example, when it is necessary to replace an old grinding wheel (see Figure 3 When replacing the grinding wheel 3), first, remove the fixing parts of the old grinding wheel, then take out the disassembly assembly 40 stored in the disassembly hole group 200 of the support part 20, and push the old grinding wheel out of the grinder through the disassembly assembly 40. Then connect the connecting part to the external lifting ring 4, and control the lifting ring 4 to move to adjust the installation position, so that the support part 20 is aligned with the corresponding hole of the old grinding wheel, and then connect the support part 20 and the old grinding wheel through the disassembly assembly 40. Finally, connect the cantilever crane hook through the lifting ring 4 to remove the old grinding wheel connected to the support part 20.

[0044] At the same time, when a new grinding wheel needs to be installed (see Figure 3 When the grinding wheel 3 is in the middle, the support part 20 is aligned with the corresponding hole of the new grinding wheel by controlling the lifting ring 4, and the support part 20 and the new grinding wheel are connected by the disassembly assembly 40, and then the new grinding wheel is lifted and moved to the installation position of the grinder. Then the new grinding wheel is pushed into the installation position of the grinder by the disassembly assembly 40, and the fixing parts of the new grinding wheel are locked. Then the disassembly assembly 40 is taken out, and the support part 20 is separated from the new grinding wheel, and the installation of the new grinding wheel is completed. Finally, the disassembly assembly 40 is stored in the corresponding hole position of the disassembly hole group 200 for the next use.

[0045] On the other hand, the disassembly and assembly device 1 of the embodiment of the present application can semi-automatically realize the disassembly and assembly of the grinding wheel 3, effectively improving the disassembly and assembly efficiency, saving time and labor costs. At the same time, it also greatly reduces the risk of collision and damage to the surface of the grinding wheel 3. In addition, the disassembly and assembly device 1 of the embodiment of the present application is particularly suitable for disassembly and assembly of grinding wheels 3 with larger sizes in large grinders 2.

[0046] refer to Figure 1 and Figure 3 ,Although Figure 1 The above-mentioned four first connection holes 300 are exemplarily shown in the figure, but the embodiment of the present application does not specifically limit the number of the first connection holes 300. For example, two, three, six, seven, etc. first connection holes 300 can also be set, which can be selected according to the actual application.

[0047] Therefore, the connection part 30 of the disassembly and assembly device 1 is provided with four first connection holes 300, and any one of the four first connection holes 300 can be used to connect with the external lifting ring 4. That is to say, under different working conditions, the connection position with the external lifting ring 4 can be adjusted arbitrarily, so that the disassembly and assembly body 10 is perpendicular to the ground, and the support part 20 arranged at the other end of the disassembly and assembly body 10 can maintain balance, thereby ensuring that the grinding wheel 3 connected to the support part 20 will not tilt during the installation, disassembly and transportation process, thereby improving the disassembly and assembly efficiency.

[0048] Exemplarily, the connecting portion 30 is L-shaped. Designing the supporting portion 20 as an L-shaped structure can facilitate the connection of the external lifting ring 4 to any first connecting hole 300 of the supporting portion 20, and at the same time, it is also convenient for the supporting portion 20 to be connected to the detachable main body 10, so that when the supporting portion 20 is connected to the lifting ring 4, the detachable main body 10 can be as vertical as possible to the ground without tilting.

[0049] refer to Figure 5In a possible implementation, the disassembly assembly 40 of the embodiment of the present application includes two guide rods 401, four top screws 402 and two screws 403. The guide rods 401, top screws 402 and screws 403 as disassembly tools can all play an auxiliary role in the installation and disassembly process of the grinding wheel. The embodiment of the present application does not specifically limit the number of the guide rods 401, top screws 402 and screws 403. For example, the disassembly assembly 40 may include three, four, five or other numbers of guide rods 401. For example, the disassembly assembly 40 may include two, three, six or other numbers of top screws 402. For another example, the disassembly assembly 40 may include three, four, five, six or other numbers of screws 403. As long as they can be accommodated in the corresponding hole positions of the disassembly hole group 200, they are all within the protection scope of the embodiment of the present application.

[0050] Refer to Figure 2 Combined with Figure 5 In a possible implementation manner, the above-mentioned disassembly and assembly hole group 200 of the embodiment of the present application includes two first accommodating holes 201, four second accommodating holes 202 and two third accommodating holes 203 that are spaced apart from each other.

[0051] Therefore, when the disassembly and assembly device is not in use or has been used, the two guide rods 401 in the disassembly and assembly component 40 are accommodated in the corresponding two first accommodating holes 201, the four top screws 402 are accommodated in the corresponding four second accommodating holes 202, and the two screws 403 are accommodated in the corresponding two third accommodating holes 203.

[0052] Accordingly, the embodiment of the present application does not impose any specific restriction on the number of the first accommodating hole 201, the second accommodating hole 202 and the third accommodating hole 203. For example, the support portion 20 can be provided with three, four, five or other numbers of the first accommodating holes 201. For example, the support portion 20 can be provided with two, three, six or other numbers of the second accommodating holes 202. For another example, the support portion 20 can be provided with three, four, five, six or other numbers of the third accommodating holes 203. As long as they can respectively accommodate the above-mentioned guide rod 401, top screw 402 and screw 403, they all fall within the protection scope of the embodiment of the present application.

[0053] Exemplarily, the support portion 20 of the embodiment of the present application further includes two second connection holes 210. The two second connection holes 210 are used for screwing with two screws 403 in the disassembly assembly 40. The embodiment of the present application does not specifically limit the number of the second connection holes 210. For example, the support portion 20 can be provided with three, four, five, six, etc. second connection holes 210, as long as they can be screwed with the screws 403 respectively, they all belong to the protection scope of the embodiment of the present application.

[0054] In a possible implementation manner, along the second direction (eg, the circumference of the support portion, such as Figure 2 The above-mentioned disassembly hole group 200 and the two second connection holes 210 are symmetrically arranged on the support part 20. Therefore, the embodiment of the present application only takes a part of the support part 20 as an example for description.

[0055] Specifically, along Figure 2 In the R1 direction shown in FIG. 1 , a portion of the support portion 20 is provided with a first receiving hole 201, a third receiving hole 203, a second connecting hole 210 and two second receiving holes 202 in sequence. Figure 2 In the R direction shown in FIG. 1 , the first receiving hole 201, the third receiving hole 203, the second connecting hole 210 and the two second receiving holes 202 are arranged to be spaced apart from each other.

[0056] Based on the above description of the structure of the disassembly and assembly device 1, the working principle of the disassembly and assembly device 1 will be described in detail below in conjunction with the accompanying drawings.

[0057] refer to Figures 1 to 5 , for the installation of grinding wheel 3:

[0058] First, connect the external lifting ring 4 to any first connecting hole 300 of the connecting part 30, and then control the lifting ring 4 to correspond the disassembly and assembly device 1 connected to the lifting ring 4 to the corresponding hole (not shown in the figure) of the grinding wheel 3 to be installed, and the corresponding hole corresponds to the above-mentioned second connecting hole 210 of the supporting part 20; take out the screw 403 originally accommodated in the third accommodating hole 203, and screw the screw 403 into the second connecting hole 210 to realize the connection between the supporting part 20 and the grinding wheel 3.

[0059] Secondly, the grinding wheel 3 is moved by controlling the lifting ring 4 until it reaches the installation position of the grinding machine 2; the guide rod 401 originally accommodated in the first accommodating hole 201 is taken out, and the guide rod 401 is screwed into the installation hole 3000 of the grinding wheel 3, the hole position of the grinding wheel 3 is accurately located, and the grinding wheel 3 is pushed into the installation position of the grinding machine 2 through the guide rod 401.

[0060] Then, the grinding wheel 3 is fixed, for example, by inserting the fixing screws of the grinding wheel 3 itself into the corresponding mounting holes 3000 to achieve locking of the grinding wheel 3 and the grinding machine 2 .

[0061] Finally, loosen the screw 403 screwed in the second connecting hole 210 to separate the support portion 20 from the grinding wheel 3, and take out the guide rod 401; and store the guide rod 401 and the screw 403 in the first receiving hole 201 and the third receiving hole 203 again.

[0062] refer to Figures 1 to 5 , for the disassembly of grinding wheel 3:

[0063] First, remove the fixing parts of the grinding wheel 3, for example, remove the fixing screws of the mounting hole 3000. Take out the guide rod 401 originally accommodated in the first accommodation hole 201, and screw the guide rod 401 into the mounting hole 3000 of the grinding wheel 3; at the same time, take out the top screw 402 originally accommodated in the second accommodation hole 202, and use the top screw 402 to push the grinding wheel 3 out of the grinding wheel spindle. At this time, the grinding wheel 3 is supported by the guide rod 401.

[0064] Secondly, connect the external lifting ring 4 to any one of the first connecting holes 300 of the connecting part 30, and then correspond the disassembly and assembly device 1 connected to the lifting ring 4 to the corresponding hole (not shown) of the grinding wheel 3 to be installed by controlling the lifting ring 4. Then take out the screw 403 originally accommodated in the third accommodating hole 203, and screw the screw 403 into the second connecting hole 210 to realize the connection between the supporting part 20 and the grinding wheel 3.

[0065] At this time, the guide rod 401 screwed into the installation hole 3000 is taken out. For example, the guide rod 401 and the top screw 402 can be stored in the first receiving hole 201 and the second receiving hole 202 respectively.

[0066] Then, the grinding wheel 3 is removed by controlling the lifting ring 4. Finally, the screw 403 screwed in the second connecting hole 210 is loosened to separate the supporting part 20 from the grinding wheel 3, and the screw 403 is stored in the third receiving hole 203.

[0067] In summary, the normal weight of the grinding wheel 3 is about 30KG, and the weight of some grinding wheels exceeds 50KG. Therefore, it is laborious to carry the grinding wheel manually in the installation and removal process, and there is a risk of collision and damage. The disassembly and assembly device 1 of the embodiment of the present application can greatly reduce the risk of collision and damage to the surface of the grinding wheel 3, and can semi-automatically realize the disassembly and installation of the grinding wheel 3, effectively improving the disassembly and installation efficiency, saving time and labor costs, and the disassembly and assembly device 1 is suitable for the disassembly and assembly of the grinding wheel 3 with larger size specifications in the large grinder 2.
