Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a small particle end face grinding resin grinding wheel structure and its processing device. Background Technology

[0002] Small-particle end-face grinding wheels are less prone to clogging during use due to their larger interparticle spacing. However, when processing with this type of grinding wheel, it is necessary to bond the small particles (also called pressing blocks) to the substrate piece by piece. Because of the large number of particles and the long bonding time, the adhesive is prone to hardening when left for a long time. In order to reduce the impact of this factor on the product, multiple people need to bond the particles at the same time. Since each person has a different technique, the bonding strength varies, making it impossible to ensure the quality of the grinding wheel.

[0003] Taking a small-particle grinding wheel with a diameter of 430mm as an example, each grinding wheel requires the bonding of more than 300 pressing blocks. Assuming three people are needed to bond one grinding wheel, it used to take about an hour. However, since it is bonded by hand, the efficiency is low, and there are differences each time, which can lead to occasional instances of blocks falling off. This can result in minor issues such as customers having to return or repair the product, or even damage to the customer's workpiece and create safety hazards. Utility Model Content

[0004] This utility model proposes a resin grinding wheel structure for grinding the end face of small particles and its processing device. The combination of the annular groove and the positioning groove facilitates the bonding of the pressing block, increases the bonding strength of the pressing block, and improves the production efficiency of the grinding wheel.

[0005] The technical solution of this utility model is implemented as follows: a resin grinding wheel structure for grinding small particles includes a matrix, an inner hole with the same center is provided on the matrix, annular grooves of different diameters are provided on the end face of the matrix, positioning grooves are evenly distributed along the circumferential direction in the annular grooves, adhesive is filled in the annular grooves, and a pressing block is bonded and fixed in the positioning groove.

[0006] Furthermore, annular grooves of different diameters are arranged concentrically with the base.

[0007] A processing device for grinding resin grinding wheel structures on the end face of small particles includes a base, a positioning post on the base for positioning the inner hole of the substrate, a vertically lifting rotating shaft directly above the positioning post, a push plate on the rotating shaft, the push plate being arranged radially, a vertical guide cylinder on the push plate for feeding pressing blocks one by one, the guide cylinder corresponding one-to-one with the annular groove, and only one pressing block can fall between the guide cylinder and the bottom of the positioning groove.

[0008] Furthermore, a downwardly inclined elastic metal sheet is provided on one side of the lower end of the guide cylinder, and the elastic metal sheet is located on the side away from the rotation direction of the guide cylinder.

[0009] Furthermore, the inner cavity of the guide cylinder matches the pressing block, and the pressing block moves downward in a single vertical stack within the guide cylinder.

[0010] Furthermore, the push plate has an elongated hole along the radial direction, and a fastening bolt is fixed on the guide cylinder. The fastening bolt passes through the elongated hole and is screwed with a lock nut.

[0011] Furthermore, the rotating shaft is connected to a rotary motor, and the rotary motor is connected to a vertical lifting mechanism.

[0012] The beneficial effects of this utility model are: This invention utilizes the combination of annular grooves and positioning grooves to facilitate quick determination of the bonding position of the pressing block. Simultaneously, the annular grooves are filled with adhesive, which facilitates the bonding of the pressing block, increasing its bonding strength and improving the production efficiency of the grinding wheel. If manual bonding were still used, the working time for completing one grinding wheel would be reduced from 1 hour for 3 people to 0.5 hours for 3 people, increasing efficiency by 50%, significantly improving production efficiency and reducing production costs.

[0013] To further improve production efficiency and shorten bonding time, the processing device of this invention, as the rotating shaft rotates, feeds the pressed blocks one by one into the positioning groove through the guide cylinder, eliminating the need for manual bonding and further improving production efficiency. Furthermore, by incorporating an elastic metal sheet, after the pressed block enters the positioning groove, the elastic metal sheet applies downward pressure to the pressed block, ensuring it fully falls into the positioning groove and guaranteeing bonding quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figure 1 As shown, a resin grinding wheel structure for small particle end face grinding includes a substrate 1, an inner hole 2 with the same center is provided on the substrate 1, and annular grooves 3 with different diameters are provided on the end face of the substrate 1. The annular grooves 3 with different diameters are arranged with the same center as the substrate 1. Positioning grooves 4 are evenly distributed in the circumferential direction in the annular grooves 3. The annular grooves 3 are filled with adhesive, and pressing blocks 5 are bonded and fixed in the positioning grooves 4.

[0019] The bonding process for the resin grinding wheel structure for small particle end face grinding is as follows: The substrate 1 is machined to the finished size. First, a circular groove 3 is machined, then a positioning groove 4 is machined inside the circular groove 3. Adhesive is applied to the circular groove 3 using a glue gun, then smoothed to fill the groove 3 with adhesive. The pressing block 5 is placed into the positioning groove 4, and adhesive is pressed out around the pressing block 5. If the adhesive is AB glue, metal glue, or epoxy resin glue, a glue gun is used to apply the adhesive until the circular groove 3 is filled with adhesive.

[0020] Example 2 like Figure 2 and 3 As shown in Example 1, the processing device for grinding resin grinding wheel structures on the end faces of small particles includes a base 6. A positioning post 7 is fixed on the base 6. The positioning post 7 is used to position the inner hole 2 of the substrate 1. The positioning post 7 is placed coaxially with the substrate 1. A vertically lifting rotating shaft 8 is arranged directly above the positioning post 7. The rotating shaft 8 is connected to a rotary motor 9. The rotary motor 9 is connected to a vertical lifting mechanism 10, which can be a vertical cylinder or a vertical hydraulic cylinder, etc. The vertical lifting mechanism 10 drives the rotating shaft 8 to move downward, and the rotary motor 9 drives the rotating shaft 8 to rotate.

[0021] The rotating shaft 8 and the positioning column 7 are coaxially arranged. A push plate 11 is fixed on the rotating shaft 8. The push plate 11 is arranged radially and has a vertical guide cylinder 12. The guide cylinder 12 is used to feed the pressing blocks 5 one by one. The guide cylinder 12 corresponds one-to-one with the annular groove 3. The distance between the guide cylinder 12 and the annular groove 3 is less than the thickness of one pressing block 5. Only one pressing block 5 can fall between the guide cylinder 12 and the bottom of the positioning groove 4. That is, the distance between the guide cylinder 12 and the bottom of the positioning groove 4 is greater than the thickness of one pressing block 5 but less than the thickness of two pressing blocks 5. A downwardly inclined elastic metal sheet 13 is fixed on one side of the lower end of the guide cylinder 12. The elastic metal sheet 13 is located on the side away from the rotation direction of the guide cylinder 12.

[0022] The cross-section of the inner cavity of the guide cylinder 12 matches that of the pressing block 5. For example, if the pressing block 5 is circular, the cross-section of the inner cavity of the guide cylinder is circular; if the pressing block 5 is triangular, the cross-section is triangular; if the pressing block 5 is regular hexagonal, the cross-section is regular hexagonal, and so on. The pressing blocks 5 are vertically stacked and moved downwards in a single row within the guide cylinder 12. When the guide cylinder 12 moves to the upper side of the positioning groove 4, the inner cavity of the guide cylinder 12 is aligned with the positioning groove 4.

[0023] The method of using the processing device is as follows: The inner hole 2 of the substrate 1 is fitted onto the positioning post 7. Adhesive is applied to the annular groove 3 and smoothed. The vertical lifting mechanism 10 drives the rotating shaft 8 to move downward, so that the distance between the guide cylinder 12 and the positioning groove 4 is only enough for one pressing block 5 to fall. The pressing blocks 5 are placed vertically in a single row inside the guide cylinder 12. The rotating motor 9 drives the rotating shaft 8 to rotate. When the guide cylinder 12 moves the pressing block 5 to the positioning groove 4, the pressing block 5 falls into the positioning groove 4 due to gravity. As the guide cylinder 12 rotates, the elastic metal sheet 13 applies downward pressure to the pressing block 5 to ensure that the pressing block 5 is installed in place.

[0024] Example 3 This embodiment uses the same substrate as Embodiment 1, except that: Figure 2 and 3 As shown, the push plate 11 has an elongated hole 14 along its radial direction. A fastening bolt 15 is fixed to the guide cylinder 12, passing through the elongated hole 14 and threaded with a locking nut 16. To adjust the radial position of the guide cylinder 12, loosen the locking nut 16, move the guide cylinder 12 along the elongated hole 14 to the desired position, and then tighten the locking nut 16. This structure facilitates adjustment of the radial position of the guide cylinder 12 as needed and is suitable for different specifications of grinding wheel structures.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
