Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel tools, in particular to a special-shaped wheel with a positively correlated water-passing structure on the entire grinding surface. Background Art

[0002] like Figure 1-2 As shown, the prior art special-shaped wheel (i.e., grinding wheel) has several water holes 10 arranged circumferentially on the base body, such as Figure 2 As shown in the middle mark C, cooling is implemented through several water holes 10. The number of water holes 10 is small and the water output is very limited, which cannot constitute an internal cooling mode for the entire grinding process. The water holes 10 are usually arranged on the circumference of the axial middle part of the grinding area of ​​the grinding wheel, such as Figure 2 As shown by the mark D, the axial direction cannot encompass the entire grinding zone, and the axial length of the water hole 10 is smaller than the axial length of the grinding zone. When the workpiece initially contacts the grinding wheel or is about to leave the grinding wheel, if the contact point is not in the area axially covered by the water hole 10, no cooling or very weak cooling will be obtained. The water hole 10 is usually circular, resulting in a relatively small water flow rate at the upper and lower ends of the grinding wheel. In the external cooling mode, it is difficult to cool the small diameter area of ​​the grinding wheel due to the adverse effect of centrifugal force. An airflow barrier will be formed during the high-speed rotation of the grinding wheel. Under the action of the airflow barrier, the problem of high-speed grinding is more serious. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a special-shaped wheel with a positively correlated water-passing structure on the entire grinding surface in response to the deficiencies of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a special-shaped wheel with a full grinding surface positively correlated water-passing structure, comprising a base, a grinding layer attached to the outer wall of the base, the outer circumferential surface of the grinding layer being a grinding surface, a water inlet provided on the top surface of the base, and a connecting hole for connecting external equipment provided on the bottom surface thereof, and also comprising a plurality of water-passing grooves, the plurality of water-passing grooves being arranged around the central axis of the base and densely arranged on the base, the water-passing grooves connecting the inner side of the base and the grinding surface, and the water-passing grooves axially covering the entire grinding surface, that is, the axial height of the water-passing groove opening encompasses the axial height of the grinding area of ​​the workpiece, and the cumulative total circumferential length of the water-passing grooves corresponding to each axial grinding point on the grinding surface is positively correlated with the grinding area of ​​the grinding point.

[0005] The positive correlation mentioned above means that as the independent variable increases, the dependent variable also increases. That is, the water groove opening at each axial point is positively correlated with the machining allowance (grinding area at that point), that is, the larger the machining allowance, the larger the water groove opening.

[0006] On the basis of the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the cumulative total circumferential length of the water grooves corresponding to each axial point on the grinding surface is n*Wi, wherein i is the grinding point on the grinding surface, n is the number of water grooves, and Wi is the opening width of the water groove corresponding to the grinding point i.

[0008] Assume that the grinding area at point i is S, and the cumulative total circumference length (n*Wi) is proportional to the grinding area S.

[0009] The beneficial effects of the present invention are:

[0010] 1. The water supply enters from the water inlet on the end face of the special-shaped wheel, and the water troughs are densely arranged around the circumference to cool the working surface.

[0011] 2. Water grooves are set on the entire grinding surface of the axial direction of the special-shaped wheel, which is less affected by the air flow barrier and is densely arranged to easily form an internal cooling mode.

[0012] 3. Use the positive effect of centrifugal force to make the cooling water cover the entire grinding surface of the special-shaped wheel.

[0013] 4. The opening of the water groove at each axial point is positively correlated with the machining allowance (grinding area at that point), that is, the larger the machining allowance, the larger the opening of the water groove.

[0014] 5. It solves the technical problem of applying cooling water to the entire grinding surface during one-time production, greatly reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] like Figure 3-5As shown, a special-shaped wheel with a full grinding surface positively correlated water-through structure includes a base 1, an outer wall of the base 1 is attached with a grinding layer, the outer circumferential surface of the grinding layer is a grinding surface 101, the top surface of the base 1 is provided with a water inlet, and the bottom surface is provided with a connecting hole for connecting external equipment, and also includes a plurality of water grooves 2, a plurality of the water grooves 2 are surrounded by the central axis of the base 1 and are densely arranged on the base 1, the water grooves 2 are connected to the inner side of the base 1 and the grinding surface 101, and the water grooves 2 axially cover the entire grinding surface 101, that is, the axial height of the opening of the water grooves 2 includes the axial height of the grinding area of ​​the workpiece 10, and the cumulative total circumferential length of the water grooves 2 corresponding to each axial grinding point on the grinding surface 101 is positively correlated with the grinding area of ​​the grinding point.

[0036] Specifically, the total cumulative circumferential length of the water grooves 2 corresponding to each axial point on the grinding surface 101 is n*Wi, where i is the grinding point on the grinding surface 101, n is the number of water grooves 2, and Wi is the opening width of the water groove 2 corresponding to the grinding point i.

[0037] Assume that the grinding area at point i is S, and the cumulative total circumference length (n*Wi) is proportional to the grinding area S.

[0038] The machining allowance increases gradually from the inner diameter to the outer diameter, and the opening width of the water trough increases gradually from the inner diameter to the outer diameter.

[0039] Different workpiece shapes have different grinding areas at different axial points, such as Figure 6 As shown, the grinding area S1 at point A is larger than the grinding area S2 at point B. The larger the grinding area, the more water is needed for cooling. Therefore, the water trough opening can be designed with different opening sizes based on water consumption. As shown in the figure, point A requires more water than point B, so the corresponding water trough opening width W1 is designed to be larger than W2. The total circumferential length of the water supply channel at each axial point on the grinding surface (n*W) is positively correlated with the grinding area (S) at that point.

[0040] Optionally, as an embodiment of the present invention, the total cumulative circumferential length of the water grooves 2 corresponding to each axial point on the grinding surface 101 is n*Wi, wherein i is the grinding point on the grinding surface 101, n is the number of water grooves 2, and Wi is the opening width of the water groove 2 corresponding to the grinding point i.

[0041] In the above embodiment, the opening width of the water groove 2 corresponding to the position with large machining allowance is increased to meet the cooling demand.

[0042] Optionally, as an embodiment of the present invention, Figure 7As shown, it also includes a base water-through spiral groove 3, which is arranged in a spiral manner at the middle of the inner wall of the base 1, and the base water-through spiral groove 3 is recessed into the inside of the base 1.

[0043] In the above embodiment, when the special-shaped wheel rotates, a portion of the water is axially raised under the action of the spiral groove and supplied to a portion with a larger grinding (cutting) area.

[0044] Optionally, as an embodiment of the present invention, Figure 4 As shown, it also includes a pad 4 for connecting to an external device. The pad 4 is an annular block structure with a connecting hole in the center. The connecting hole of the pad 4 is coaxial with the connecting hole of the base 1 and is fixedly arranged inside the base 1.

[0045] Optionally, as an embodiment of the present invention, Figure 7 As shown, it also includes a pad water-passing spiral groove 5, which is arranged in a spiral manner in the middle of the outer wall of the pad 4, and the pad water-passing spiral groove 5 is recessed into the interior of the pad 4.

[0046] In the above embodiment, when the special-shaped wheel rotates, a portion of the water is axially raised under the action of the spiral groove and supplied to a portion with a larger grinding (cutting) area.

[0047] Optionally, as an embodiment of the present invention, Figure 8-10 As shown, it also includes a pumping component, which is arranged between the pad 4 and the base 1 and located at the water inlet of the base 1; the pumping component 6 includes an inner ring 601, an outer ring 602 and a plurality of pumping blades 603, the outer ring 602 is sleeved outside the inner ring 601, and the pumping blades 603 are connected across between the inner ring 601 and the outer ring 602, and the plurality of pumping blades 603 are distributed circumferentially and at intervals.

[0048] In the above embodiment, the pumping blades 603 can pump cooling water into the grinding wheel to increase the water supply and play a role in supporting the grinding wheel.

[0049] Optionally, as an embodiment of the present invention, Figure 11 As shown, a pad annular groove body 7 is provided at the corresponding position of the pad 4 and the pumping component 6, and a base annular groove body 8 is provided at the corresponding position of the base 1 and the pumping component 6, and the inner ring 601 and the outer ring 602 are respectively embedded in the pad annular groove body 7 and the base annular groove body 8 and fixedly connected as one.

[0050] Different workpiece shapes have different grinding areas at different axial points, such as Figure 12-14As shown, for example, an arc wheel has an arc-shaped water channel around it. Since the machining allowance near the two ends of the arc wheel is larger than that in the middle, the width of the opening near the two ends is larger than that in the middle. Figure 13 The arrows in the figure indicate the cooling water flow path.

[0051] like Figure 15-17 As shown, for example, a small-diameter grinding wheel has an arc-shaped water channel around it. Since the machining allowance near the lower end of the small-diameter grinding wheel is larger than that in the middle and upper ends, the width of the water channel opening near the lower end is larger than that in the middle and upper ends. The water channel of the small-diameter grinding wheel gradually widens from the upper end to the lower end. Figure 17 The arrows in the figure indicate the cooling water flow path.

[0052] The water supply port of the present invention enters from the water inlet of the end face of the special-shaped wheel, and the water grooves are densely arranged circumferentially, which has the function of cooling the working surface. The water grooves 2 are set on the entire axial grinding surface of the special-shaped wheel, which is less affected by the air flow barrier and is densely arranged, which can easily form an internal cooling mode. The positive effect of centrifugal force is utilized to make the cooling water encompass the entire grinding surface of the special-shaped wheel. The opening of the water groove 2 at each axial point is positively correlated with the machining allowance (grinding area of ​​the point), that is, the larger the machining allowance, the larger the opening of the water groove 2. It solves the process problem of being difficult to implement the application of cooling water to the entire grinding surface in a one-time overall production, and greatly reduces the production cost.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
