Description

Technical Field

[0001] The utility model belongs to the field of assembly fixtures, in particular to a grinding wheel assembly device. Background Art

[0002] like Figure 1 As shown, the grinding wheel includes a substrate 1 and a plurality of abrasive blocks 2 bonded to the outside of the substrate 1, and all the abrasive blocks 2 form a complete circle. In the prior art, the inner circumference of the abrasive block 2 is generally bonded to the outer circumference of the substrate 1 manually, that is, after the staff applies glue on the inner circumference of the abrasive block 2, the abrasive block 2 is pressed on the outer circumference of the substrate 1, and the abrasive block 2 is repeatedly pressed to allow the glue to flow fully between the abrasive block 2 and the substrate 1, ensuring that the abrasive block 2 is firmly bonded. For example, a Chinese utility model patent with an authorization announcement number of CN219725848U and an authorization announcement date of 2023.09.22 discloses a grinding wheel with an abrasive block bonded to a substrate.

[0003] However, in actual production, the labor intensity of workers repeatedly pressing the abrasive block 2 is high, and after the workers become tired, they cannot ensure that different parts of the abrasive block 2 are pressed with sufficient force, resulting in the glue not being able to fully flow between the substrate 1 and the abrasive block 2. Therefore, the glue at the interface between the substrate 1 and the abrasive block 2 is uneven, which in turn leads to a loose bond between the abrasive block 2 and the substrate 1. During the subsequent use of the grinding wheel, the abrasive block 2 may fall off, causing serious safety problems.

[0004] At the same time, since the palms of the staff are uneven, the staff cannot ensure that the force on various parts of the abrasive block 2 is consistent during the process of pressing the abrasive block 2 once; at the same time, the staff needs to press the abrasive block 2 repeatedly, and it is impossible for the staff to ensure consistent force each time they press the abrasive block 2, which results in the glue not being able to fully flow between the substrate 1 and the abrasive block 2, that is, the glue at the interface between the substrate 1 and the abrasive block 2 is uneven, resulting in the abrasive block 2 and the substrate 1 The bonding is not reliable, and the abrasive block 2 will fall off during the subsequent use of the grinding wheel, causing serious safety problems. Utility Model Content

[0005] The utility model aims to provide a grinding wheel assembly device to solve the problems in the prior art that, due to the manual assembly of the abrasive block and the substrate, the labor intensity of the staff when repeatedly pressing the abrasive block is high, and after the staff become tired, it is impossible to ensure that different parts of the abrasive block are pressed with sufficient force; at the same time, the palms of the staff are uneven, and it is impossible to ensure that the force applied to various parts of the abrasive block is consistent, which results in the glue not being able to fully flow between the substrate and the abrasive block, the glue at the interface between the substrate and the abrasive block is uneven, resulting in the abrasive block and the substrate The bonding is not reliable, which further leads to the phenomenon that the abrasive block falls off during the use of the grinding wheel, causing a serious safety problem.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the grinding wheel assembly device provided by the utility model is:

At least one of the inner clamping member and the outer clamping member is provided with a power source for driving the clamping member to move so that the inner clamping member and the outer clamping member clamp the base and the abrasive block.

[0008] Furthermore, the central angle of the arc-shaped depression satisfies: the central angle of the arc-shaped depression is not less than the central angle of a single abrasive block.

[0009] Furthermore, the circumferential length of the outer clamping member is greater than the circumferential length of the inner clamping member.

[0010] Furthermore, the power source is a finger cylinder, which also constitutes the base, and the inner clamping member and the outer clamping member are respectively fixedly connected to two pneumatic fingers of the finger cylinder.

[0011] Furthermore, the inner clamping member and the outer clamping member each include a clamping plate body and a connecting structure for detachably connecting the clamping plate body to the pneumatic finger.

[0012] Furthermore, the connection structure includes a first connection plate and a second connection plate which are perpendicular to each other, the first connection plate is fixedly connected to the pneumatic finger, and the second connection plate is fixedly connected to the corresponding inner clamp or outer clamp.

[0013] Furthermore, the clamping plate body is perpendicular to the second connecting plate, and the clamping plate body and the first connecting plate are respectively located at two ends of the second connecting plate to form a "Z"-shaped clamping plate.

[0014] Furthermore, the inner clamping member and the outer clamping member are both split structures.

[0015] Furthermore, the pneumatic finger is fixedly connected to the first connecting plate by means of screws.

[0016] Furthermore, the first connecting plate is connected to a side of the pneumatic finger opposite to the other pneumatic finger.

[0017] The beneficial effects of the grinding wheel assembly device of the utility model are as follows: the utility model is a pioneering invention. When the grinding wheel assembly device in the technical solution is used to assemble the grinding wheel, the arc-shaped protrusion of the inner clamping piece can fit with the inner wall of the base, and the arc-shaped depression of the outer clamping piece can fit with the outer wall of the abrasive block. The inner clamping piece and the outer clamping piece arranged opposite to each other can be controlled by the power source to clamp the base and the abrasive block, so as to conveniently press the abrasive block on the base and reduce the labor intensity of the workers; at the same time, the inner clamping piece and the outer clamping piece are controlled by the power source to clamp the base and the abrasive block. Since the arc-shaped depression of the outer clamping piece fits with the outer wall of the abrasive block, the force consistency of each part of the abrasive block can be ensured, so that the glue can flow fully between the base and the abrasive block, and the glue at the interface between the base and the abrasive block can be ensured to be uniform, so as to ensure that the abrasive block and the base are firmly bonded, and the phenomenon of the abrasive block falling off during the use of the grinding wheel can be avoided.

[0024] In order to solve the problem of the abrasive block on the substrate being pressed manually in the background technology, the utility model proposes a grinding wheel assembly device, which squeezes the grinding wheel through relatively movable inner and outer clamping parts, thereby pressing the abrasive block onto the substrate. Since the arc-shaped depression of the outer clamping part fits with the outer wall of the abrasive block, the force consistency of various parts of the abrasive block can be ensured, so that the glue can flow fully between the substrate and the abrasive block, the glue at the interface between the substrate and the abrasive block is uniform, the abrasive block and the substrate are firmly bonded, and the phenomenon of abrasive block falling off during the use of the grinding wheel is avoided.

[0025] The present invention is further described in detail below in conjunction with the embodiments.

[0026] Specific embodiment 1 of the grinding wheel assembly device provided by the utility model:

[0027] like Figures 2~4 As shown, the grinding wheel assembly device includes a base and an inner clamping member 7 and an outer clamping member 6 which are arranged on the base and opposite to each other. The side of the inner clamping member 7 opposite to the outer clamping member 6 has an arc-shaped protrusion for fitting with the inner wall of the base 1, and the side of the outer clamping member 6 opposite to the inner clamping member 7 has an arc-shaped depression for fitting with the outer wall of the abrasive block 2 and cocentric with the arc-shaped protrusion. At least one of the inner clamping member 7 and the outer clamping member 6 is configured with a power source for driving the clamping member to move so that the inner clamping member 7 and the outer clamping member 6 clamp the base 1 and the abrasive block 2.

[0028] When assembling a grinding wheel using the grinding wheel assembly device in the present technical solution, the arc-shaped protrusion of the inner clamping member 7 can fit with the inner wall of the base 1, and the arc-shaped depression of the outer clamping member 6 can fit with the outer wall of the abrasive block 2. The inner clamping member 7 and the outer clamping member 6 can be controlled by the power source to clamp the grinding wheel, so that the abrasive block 2 can be conveniently pressed onto the base 1, reducing the labor intensity of the workers; at the same time, the inner clamping member 7 and the outer clamping member 6 are controlled by the power source to clamp the base 1 and the abrasive block 2. Since the arc-shaped depression of the outer clamping member 6 fits with the outer wall of the abrasive block 2, the consistency of the force applied to each part of the abrasive block 2 can be ensured, so that the glue can flow fully between the base 1 and the abrasive block 2, ensuring that the glue at the interface between the base 1 and the abrasive block 2 is uniform, ensuring that the abrasive block 2 and the base 1 are firmly bonded, and avoiding the phenomenon of the abrasive block 2 falling off during the use of the grinding wheel.

[0029] like Figure 4As shown, in order to improve the assembly efficiency, as a specific implementation, the central angle of the arc-shaped depression satisfies: the central angle of the arc-shaped depression is not less than the central angle of the single abrasive block 2. The central angle of the arc-shaped depression is not less than the central angle of the single abrasive block 2, so that the entire abrasive block 2 can be pressed on the base 1 at one time. At the same time, the larger pressing contact area can ensure that the glue fully flows and fills the contact between the abrasive block 2 and the base 1, thereby further improving the quality of the grinding wheel. Of course, in other specific implementations, the central angle of the arc-shaped depression can also be smaller than the central angle of the single abrasive block 2. At this time, the abrasive block 2 needs to be pressed multiple times to ensure that all parts of the abrasive block 2 are pressed on the base; although the central angle of the arc-shaped depression is smaller than the central angle of the single abrasive block 2, when the pressing contact area is larger, it can still ensure that the glue fully flows and fills the contact between the abrasive block 2 and the base 1.

[0030] like Figure 4 As shown, in order to facilitate the staff to distinguish the inner clamping member 7 from the outer clamping member 6, as a specific embodiment, the circumferential length of the outer clamping member 6 is greater than the circumferential length of the inner clamping member 7, and the staff can easily distinguish the inner clamping member 7 from the outer clamping member 6 by the length of the clamping plate. Of course, in other specific embodiments, the circumferential length of the outer clamping member 6 can also be less than the circumferential length of the inner clamping member 7, or the circumferential length of the outer clamping member 6 is equal to the circumferential length of the inner clamping member 7. In this case, the staff needs to carefully distinguish the inner clamping member 7 from the outer clamping member 6 according to the arc-shaped protrusions and arc-shaped depressions.

[0031] like Figures 2~4 As shown, in order to make the structure simpler, as a specific implementation, the inner clamping member 7 is an inner clamping plate, and the outer clamping member 6 is an outer clamping plate. However, in other specific implementations, the inner clamping member 7 may also be an elliptical or special-shaped structure with an arc-shaped protrusion; the outer clamping member 6 may also be an elliptical or special-shaped structure with an arc-shaped depression. In this embodiment, the specific structures of the inner clamping member 7 and the outer clamping member 6 are not limited, as long as the inner clamping member 7 has an arc-shaped protrusion and can clamp the inner wall of the substrate 1, and the outer clamping member 6 has an arc-shaped depression and can fit the outer wall of the abrasive block 2.

[0032] Specifically, as a specific implementation, the power source is the finger cylinder 3, and the finger cylinder 3 also constitutes a base, and the inner clamp 7 and the outer clamp 6 are respectively fixedly connected to the two pneumatic fingers 4 of the finger cylinder 3. Specifically, the inner clamp 7 and the outer clamp 6 each include a clamp body and a connection structure for detachably connecting the clamp body with the pneumatic fingers 4, and the two pneumatic fingers 4 of the finger cylinder 3 are detachably fixedly connected with the corresponding inner clamp 7 or outer clamp 6 through the connection structure. The connection structure includes a first connecting plate 8 and a second connecting plate 9 perpendicular to each other, the first connecting plate 8 is fixedly connected to the pneumatic fingers 4, and the second connecting plate 9 is fixedly connected to the corresponding inner clamp 7 or outer clamp 6; the clamp body is perpendicular to the second connecting plate 9, and the clamp body and the first connecting plate 8 are respectively located at the two ends of the second connecting plate 9 to form a "Z"-shaped clamp, and the inner clamp and the outer clamp are both split structures. The pneumatic finger 4 is fixedly connected to the first connecting plate 8 by means of screws 5 , and the first connecting plate 8 is connected to a side of the pneumatic finger 4 opposite to the other pneumatic finger 4 .

[0033] However, in other different specific embodiments, the power source can also be a direct-acting drive mechanism such as other linear hydraulic cylinders, the outer clamping member 6 moves, and the inner clamping member 7 does not move; or, the inner clamping member 7 and the outer clamping member 6 are welded to the pneumatic finger 4; or, the inner clamping member 7 and the outer clamping member 6 are directly connected to the pneumatic finger 4 as a connecting part close to the pneumatic finger 4, and the connecting part does not contact the grinding wheel; or, the connecting structure is only a connecting plate, and the two ends of one side of the connecting plate are respectively connected to the pneumatic finger 4 and the corresponding clamping plate; or, the first connecting plate and the clamping plate body are both located in the middle of the second connecting plate to form a "cross" shaped clamping plate; or, the inner clamping member and the outer clamping member are integrally cast parts; or, the first connecting plate 8 is connected to the side of the pneumatic finger 4 opposite to the other pneumatic finger 4; or, the pneumatic finger 4 and the first connecting plate 8 are fixedly connected by pinning or the like.

[0034] The power source is the finger cylinder 3, which has a simple structure, and the volume and weight of the entire grinding wheel assembly device are small, which is convenient for the staff to use; the clamping plate is detachably connected to the pneumatic finger 4, and the clamping plate can be replaced as needed; by setting a first connecting plate 8 and a second connecting plate 9 perpendicular to the first connecting plate 8, the clamping plate can be conveniently connected to the pneumatic finger 4, and the "Z"-shaped clamping plate can effectively increase the space between the clamping plate bodies of the inner clamping part 7 and the outer clamping part 6, so as to conveniently clamp the grinding wheel; the split structure of the clamping plate is easier to process and manufacture; by connecting the first connecting plate 8 to the side of the pneumatic finger 4 opposite to the other pneumatic finger 4, the occupied space of the entire grinding wheel assembly device can be reduced; the pneumatic finger 4 can be conveniently fixedly connected to the first connecting plate 8 by the screw 5.

[0035] Finally, it should be noted that the above are only preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
