[0059] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0063] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the angles shown in the accompanying drawings, and should not be construed as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0064] The embodiments of the present application provide a polishing device, such as Figure 1As shown, the grinding device includes a grinding unit 20 and a cooling unit 10. The grinding unit 20 includes a main shaft 201 and a grinding wheel 202 fixedly connected to the main shaft 201. The grinding wheel 202 is used for machining and grinding parts. The main shaft 201 is fixedly connected to the grinding wheel and is used to drive the grinding wheel 202 to rotate to complete the grinding work. The cooling unit 10 includes a coolant nozzle 2. The coolant nozzle 2 is used to spray coolant to cool the grinding wheel 202 and the workpiece. Through the flow of the coolant, the heat on the surfaces of the grinding wheel 202 and the workpiece is carried away to prevent the grinding wheel 202 and the workpiece from being burned.

[0065] The specific structure of the cooling unit 10 will be introduced below. As Figure 2 and Figure 3 shown, the cooling unit 10 at least includes a first guiding member 1 and a coolant nozzle 2. A first guiding groove 11 is formed on the first guiding member 1. The first guiding groove 11 has a first end 111 and a second end 112 that are oppositely arranged along its extending direction. Along the direction from the first end 111 to the second end 112, the distance between the first guiding groove 11 and the center of the first guiding member 1 gradually decreases. The coolant nozzle 2 is slidably connected to the first guiding groove 11 to adjust the position of the coolant nozzle 2 in the radial direction X of the cooling unit 10.

[0066] As Figure 1 shown, along the radial direction X of the cooling unit 10, the grinding wheel 202 is usually arranged at a position close to the center of the cooling unit 10. When the diameter of the grinding wheel 202 decreases due to wear, the position of the coolant nozzle 2 can be adjusted by controlling the coolant nozzle 2 to slide along the first end 111 to the second end 112 in the first guiding groove 11, so that it is closer to the grinding wheel 202 in the radial direction X of the cooling unit 10. Thus, the grinding wheel 202 and the surface of the workpiece can be accurately cooled, avoiding the situation of the grinding wheel 202 being burned due to excessive temperature and also avoiding the situation of defective products caused by untimely cooling of the workpiece. That is, by providing the first guiding groove 11 slidably connected to the coolant nozzle 2, the free movement of the coolant nozzle 2 in the radial direction X of the cooling unit 10 can be realized, so that the position of the coolant nozzle 2 can be adjusted according to the change in the diameter of the grinding wheel 202. Compared with the method of fixedly setting the coolant nozzle 2, the flexibility of the coolant nozzle 2 is improved, thereby improving the cooling effect of the coolant nozzle 2, and further facilitating the improvement of the service life of the grinding wheel 202 and the qualified rate of the workpiece.

[0067] When the cooling device 10 provided by the present application is not used, on average, one grinding wheel 202 can grind 1000 workpieces. After using the cooling device 10 provided by the present application, on average, one grinding wheel 202 can grind 1300 workpieces, and the working life of the grinding wheel 202 can be extended by 30%. When the cooling device 10 provided by the present application is not used, the first-pass yield of tool burning, cross striations, and grinding wheel striations of the workpieces is 90.4%. After using the cooling device 10 provided by the application, the first-pass yield of tool burning, cross striations, and grinding wheel striations of the workpieces is 94.5%, and the yield of the product can be increased by 4.1%.

[0068] In addition, when the grinding equipment changes to a grinding wheel 202 with a different diameter, the positional relationship between the coolant nozzle 2 and the grinding wheel 202 can be adjusted by controlling the sliding of the coolant nozzle 2 in the first guiding groove 11, so that the cooling device 10 can be adapted to grinding wheels 202 of different sizes, with higher versatility.

[0069] Specifically, the first guiding groove 11 can be a linear structure extending along the radial direction X of the cooling device 10, or can be Figure 3 the arc-shaped structure shown in the figure, and this embodiment does not limit this.

[0070] In a specific implementation manner, as Figure 4 and Figure 5 shown, the cooling device 10 further includes a second guiding member 3 for driving the movement of the coolant nozzle 2. A second guiding groove 31 is provided on the second guiding member 3. Along the axial direction Z of the cooling device 10, the coolant nozzle 2 sequentially passes through the first guiding groove 11 and the second guiding groove 31. When the second guiding member 3 moves relative to the first guiding member 1, the second guiding groove 31 can move relative to the first guiding groove 11 to drive the coolant nozzle 2 to slide along the first guiding groove 11.

[0071] Specifically, as Figure 3 shown, the first guiding member 1 is usually a circular ring structure. The grinding wheel 202 is located below the first guiding member 1 and is coaxially arranged with the first guiding member 1. The first guiding member 1 is provided with a plurality of first guiding grooves 11 distributed at intervals along its circumferential direction. Each first guiding groove 11 is respectively slidably connected with a coolant nozzle 2 to perform cooling in the circumferential direction of the grinding wheel 202, ensuring that the entire grinding wheel 202 can be cooled and improving the cooling efficiency of the cooling device 10.

[0072] When the first guiding groove 11 is a linear structure extending along the radial direction X of the cooling device 10, the second guiding groove 31 should also be a linear structure extending along the radial direction X of the cooling device 10. The number of the second guiding members 3 can be multiple, and the multiple second guiding members 3 are arranged at intervals along the circumferential direction of the first guiding member 1. Each second guiding member 3 corresponds to a first guiding groove 11 respectively, and each second guiding member 3 is respectively provided with a second guiding groove 31 for cooperating with the first guiding groove 11. The second guiding member 3 can move along the radial direction X of the cooling device 10, so that the second guiding groove 31 can move relative to the first guiding groove 11 along the radial direction X of the cooling device 10, thereby enabling the coolant nozzle 2 to slide along the first guiding groove 11 driven by the second guiding groove 31, so as to realize the position adjustment of the coolant nozzle 2 in the radial direction X of the cooling device 10.

[0073] When the first guiding groove 11 is Figure 3 the arc-shaped structure shown, the second guiding member 3 can be an annular structure having the same size as the first guiding member 1. As Figure 4 and Figure 5 shown, the first guiding member 1 and the second guiding member 3 are arranged overlappingly along the axial direction Z of the cooling device 10. Along the circumferential direction of the second guiding member 3, a plurality of second guiding grooves 31 can be arranged at intervals, and the plurality of second guiding grooves 31 correspond to the plurality of first guiding grooves 11 one by one. Please refer to Figure 3 and Figure 6 shown, the projection of the first guiding groove 11 on the axial direction Z of the cooling device 10 is symmetric with respect to the radial direction X of the cooling device 10 to the projection of the second guiding groove 31 on the axial direction Z of the cooling device 10, that is, the direction of the second guiding groove 31 is opposite to that of the first guiding groove 11. Specifically, as Figure 6 shown, the second guiding groove 31 has a third end 311 and a fourth end 312 which are oppositely arranged along its extending direction. Along the direction from the third end 311 to the fourth end 312, the distance between the second guiding groove 31 and the center of the second guiding member 3 gradually decreases. The extending direction of the first guiding groove 11 is symmetric with the extending direction of the second guiding groove 31, that is, when the coolant nozzle 2 cooperates with the second guiding member 3, when sliding from the outer third end 311 to the inner 312, it moves in the counterclockwise direction; while when the coolant nozzle 2 cooperates with the first guiding member 1, when sliding from the outer first end 111 to the inner 112, it moves in the clockwise direction.

[0074] Please combine Figure 4 and Figure 7As shown, when the second guide member 3 rotates clockwise about its central axis, the second guide groove 31 rotates relative to the coolant nozzle 2. Since the structure of the second guide groove 31 is arc-shaped, the side wall of the second guide groove 31 has a tendency to drive the coolant nozzle 2 inward along the radial direction X of the cooling device 10. Also, since the coolant nozzle 2 is further disposed in the first guide groove 11, as the second guide groove 31 rotates, the position where the first guide groove 11 and the second guide groove 31 coincide along the axial direction Z of the cooling device 10 gradually transfers from the first end 111 to the second end 112, so that the coolant nozzle 2 can move along the first guide groove 11 from the first end 111 towards the direction close to the second end 112 under the drive of the second guide groove 31, thereby causing the coolant nozzle 2 to move inward in the radial direction X of the cooling device 10. Similarly, when the second guide member 3 rotates counterclockwise about its central axis, the second guide groove 31 can drive the coolant nozzle 2 to move from the second end 112 towards the direction close to the first end 111, thereby causing the coolant nozzle 2 to move outward in the radial direction X of the cooling device 10.

[0075] Since the shape and size of the second guide member 3 are the same as those of the first guide member 1, the second guide member 3 only rotates relative to the first guide member 1 and does not move along the radial direction X of the cooling device 10, which can achieve the effect of saving space.

[0076] In a specific embodiment, as Figure 5 shown, the second guide member 3 is provided with a first chute 32 extending along its circumferential direction. As Figure 9 shown, a guide pin 12 is provided on the first guide member 1, and at least a part of the guide pin 12 extends into the first chute 32. When the second guide member 3 rotates relative to the first guide member 1, the guide pin 12 slides along the first chute 32.

[0077] The sliding fit between the guide pin 12 and the first chute 32 can improve the stability of the second guide member 3 when rotating relative to the first guide member 1: along the width direction of the first chute 32, the side walls of the first chute 32 can limit and guide the guide pin 12, thereby reducing the risk of the second guide member 3 deviating or toppling relative to the first guide member 1. Moreover, along the extending direction of the first chute 32, both ends of the first chute 32 can limit the guide pin 12, thereby restricting the rotation angle of the second guide member 3 relative to the first guide member 1 and avoiding damage to the coolant nozzle 2.

[0078] Specifically, as Figure 6 shown, a plurality of first chutes 32 can be provided at intervals in the circumferential direction of the second guide member 3, and a plurality of guide pins 12 are correspondingly provided on the first guide member 1. The plurality of guide pins 12 are respectively in one-to-one cooperation with the plurality of first chutes 32 to further improve the rotation stability of the second guide member 3.

[0079] In a specific embodiment, asFigure 8 As shown, the coolant nozzle 2 has a main body portion 21 and a limiting protrusion 22. The main body portion 21 is used to extend into the first guiding groove 11 to slidably connect with the first guiding member 1, and / or the main body portion 21 is used to extend into the second guiding groove 31 to slidably connect with the second guiding member 3; the limiting protrusion 22 protrudes radially outward along the main body portion 21. As Figure 6 shown, the limiting protrusion 22 overlaps on the surface of the second guiding member 3 facing the first guiding member 1. The limiting protrusion 22 can be in abutting cooperation with the surface of the second guiding member 3 in the axial direction Z of the cooling device 10, so as to achieve the limiting effect on the coolant nozzle 2, prevent the limiting protrusion 22 from falling off from the second guiding groove 31, and improve the installation reliability of the coolant nozzle 2.

[0080] As Figure 4 shown, the cooling device 10 is further provided with a driving mechanism. The driving mechanism includes a driving rack 4. A tooth portion 33 is provided at the edge of the second guiding member 3. The driving rack 4 meshes with the tooth portion 33. When the driving rack 4 moves forward along its length direction, it can drive the second guiding member 3 to rotate relative to the first guiding member 1, so as to achieve the driving of the coolant nozzle 2.

[0081] Specifically, the driving mechanism further includes a rack guiding block 5 fixedly connected to the first guiding member 1. As Figure 4 and Figure 5 shown, the rack guiding block 5 includes a front plate 52 fixedly connected to the first guiding member 1, a side plate 54 fixedly connected to the front plate 52, and a rear plate 53 fixedly connected to the side plate 54. The front plate 52, the side plate 54 and the rear plate 53 jointly enclose an installation space. The driving rack 4 is slidably connected in the installation space. One of the rack guiding block 5 and the driving rack 4 is provided with a second sliding groove 51, and the other is provided with a slider 41. The slider 41 is slidably connected to the second sliding groove 51, so as to facilitate the forward and backward movement of the driving rack 4 to drive the second guiding member 3 to rotate relative to the first guiding member 1.

[0082] Among them, as Figure 5 shown, the rear plate 53 is located below the second guiding member 3, and a notch 531 is provided on the side of the rear plate 53 facing the inner side of the second guiding member 3, for avoiding the coolant nozzle 2 and preventing interference with the movement path of the coolant nozzle 2.

[0083] In addition, the grinding device may further include a control device, which is electrically connected or signal-connected to the main shaft 201 and is used to control the rotation of the main shaft 201 to drive the grinding wheel 202 to grind the workpiece; the control device is also electrically connected or signal-connected to the cooling device 10, and the control device is further used to adjust the position of the coolant nozzle 2 in the radial direction of the cooling device 10 according to the number of rotations of the main shaft 201. That is, the control device can control the rotation of the main shaft 201 by setting program codes and control the moving distance of the driving rack 4 according to the number of rotations of the main shaft 201, so as to drive the driving rack 4 to drive the second guide member 3. That is, the grinding device can automatically adjust the position of the coolant nozzle 2 in the radial direction X of the cooling device 10 according to the wear condition of the grinding wheel 202, achieving the effect of automatic control, without manual on-site adjustment. On the one hand, it saves more manpower and improves the adjustment efficiency. On the other hand, it can also adjust the position of the coolant nozzle 2 more timely and accurately.

[0084] Alternatively, the control device can also control the moving distance of the driving rack 4 according to the number of processed workpieces. For example, it can control the driving rack 4 to move 1 mm every 100 workpieces processed (which can be changed according to the actual processing situation) through a program decision statement (“IF

#865MOD 100

[0085] In the above embodiments, as Figure 2 shown, the cooling device 10 is further provided with a water tank 6 with a circular ring structure corresponding to the first guide member 1. The water tank 6 is located above the first guide member 1 and is fixedly connected to the first guide member 1 through a fixing plate 7 to shorten the flow path of the coolant and improve the cooling efficiency. As Figure 10 shown, the side wall of the water tank 6 is provided with a water inlet 61, and the coolant enters the inside of the water tank 6 through the water inlet 61 for storage. At the circumference of the water tank 6, a plurality of water outlets 62 are spaced apart at the bottom of the water tank 6. The plurality of water outlets 62 are respectively connected to the plurality of coolant nozzles 2 through hoses 63. The coolant in the water tank 6 flows to the coolant nozzles 2 through the water outlets 62 and the hoses 63 to cool and lower the temperature of the grinding wheel 202 and the workpiece. The hose 63 can move with the coolant nozzle 2 and will not hinder the movement of the coolant nozzle 2.

[0086] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
