Description

Technical Field

[0001] The invention relates to the technical field of dressers, and in particular to a method for ensuring the accuracy of a grinding wheel dresser. Background Art

[0002] The arc dresser is an important device in the field of grinding wheel dressing of grinding machines. It is mainly used to perform precise arc shape dressing on grinding wheels. The arc dresser has higher dressing accuracy and better stability, which can meet the high requirements of modern industry for grinding wheel dressing and achieve precise dressing of the arc shape of the grinding wheel, thereby ensuring the quality of grinding processing. The arc dresser usually includes a rotary structure, on which a diamond pen or other dressing tool is clamped, which contacts the grinding wheel during the rotary motion, thereby dressing the grinding wheel.

[0003] As a key equipment in precision machining, the arc grinding wheel dresser has extremely strict requirements on accuracy. There are two main positions that affect its accuracy: first, the coaxiality of the circular holes on both sides of the support seat is the basis for ensuring the stable operation of the dresser and the precise dressing of the grinding wheel profile. During the arc grinding wheel dressing process, the support seat supports and guides the rotation of the rotary unit and the swing bracket through the circular holes on both sides. If the coaxiality of the two circular holes does not meet the standard, the rotation motion will deviate, which will affect the accuracy and consistency of the dressing of the grinding wheel by the dresser; secondly, the thread gap between the diamond pen and the connecting frame. The diamond pen is fixed to the connecting frame by a threaded connection. If the thread gap is too large or unstable, the diamond pen will shake or shift during the dressing process, thus affecting the dressing accuracy. Summary of the invention

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] like Figure 1-3 As shown, a method for ensuring the accuracy of a grinding wheel dresser is provided, wherein the dresser is provided with a U-shaped support seat 1, and a rotary unit 2 is rotatably provided on both sides of the U-shaped support seat 1, and the rotary unit 2 is connected to a driving unit 4 through a transmission unit 3, and a swing bracket 5 is provided on the rotary unit 2, and a dressing unit 6 is provided in the middle of the swing bracket 5.

[0035] S1. The U-shaped support seat 1 is provided with a first supporting circular hole 11 and a second supporting circular hole 12 on both sides. During processing, the inner diameter of the first supporting circular hole 11 is smaller than the inner diameter of the second supporting circular hole 12;

[0036] S2. Take a steel shaft, the diameter of the steel shaft is the same as the inner diameter of the first supporting circular hole 11;

[0037] S3. Insert the steel shaft into the first support circular hole 11 and the second support circular hole 12, and apply a release agent on one end of the steel shaft near the second support circular hole 12;

[0038] S4. Place the U-shaped support seat 1 inserted into the steel shaft vertically so that one side of the first supporting circular hole 11 is located above the second supporting circular hole 12. Since the inner diameter of the first supporting circular hole 11 is the same as the diameter of the steel shaft, the inner diameter of the first supporting circular hole 11 is smaller than the inner diameter of the second supporting circular hole 12. Therefore, there will be a gap between the second supporting circular hole 12 and the steel shaft. Fill the gap between the steel shaft and the second supporting circular hole 12 with high-strength glue, and take out the steel shaft after the glue solidifies. At this time, the coaxiality of the first supporting circular hole 11 and the second supporting circular hole 12 is relatively high.

[0039] Specifically, the grinding wheel dresser is provided with a U-shaped support seat 1. During processing, the inner diameter of the first support circular hole 11 is deliberately made smaller than the inner diameter of the second support circular hole 12, so as to achieve high-precision coaxiality by fixing the steel shaft and high-strength glue in the subsequent steps. The steel shaft is inserted into the first support circular hole 11 and the second support circular hole 12 of the U-shaped support seat 1, and the U-shaped support seat 1 with the inserted steel shaft is placed vertically so that the first support circular hole 11 is located above the second support circular hole 12. By placing the U-shaped support seat 1 and the steel shaft vertically, the deviation caused by gravity can be reduced, thereby improving the coaxiality accuracy of the first support circular hole 11 and the second support circular hole 12, and it is easier to observe and control the flow of glue when filling with high-strength glue. The glue will fix the steel shaft in the second support circular hole 12 during the solidification process. At the same time, since the steel shaft has been accurately inserted into the first support The circular hole 11 ensures the high coaxiality between the first supporting circular hole 11 and the second supporting circular hole 12. After the glue is completely solidified, the steel shaft is taken out. At this time, due to the fixing effect of the glue and the calibration effect of the steel shaft, the coaxiality of the first supporting circular hole 11 and the second supporting circular hole 12 has reached a relatively high precision. By using the steel shaft for calibration, the accuracy of the trimmer can be significantly improved, so that it can meet the needs of high-precision processing; the method of using a steel shaft and filling with high-strength glue is relatively simple and low-cost, avoiding complex machining processes, thereby reducing production costs and time.

[0040] like Figure 3 , 4 As shown, the trimming unit 6 includes a diamond pen 61, which is arranged on a threaded rod 62. A scale sleeve 63 is sleeved on the outside of the threaded rod 62. The threaded rod 62 and the scale sleeve 63 are threadedly connected. A bushing 64 is sleeved on the outside of the scale sleeve 63. The bushing 64 is fixedly mounted on the swing bracket 5 through a bolt assembly. A locking nut 65 is arranged at the bottom of the scale sleeve 63. The locking nut 65 is located below the bushing 64. A plurality of compression springs 66 are arranged side by side between the locking nut 65 and the bushing 64. A guide sleeve 67 is arranged below the scale sleeve 63. A cylindrical pin 68 is arranged on the inner side of the guide sleeve 67. A guide groove 69 is arranged on the threaded rod 62.

[0041] Specifically, the servo arc grinding wheel dresser is powered by the driving unit 4, which is transmitted to the rotating unit 2 by the transmission unit 3. After receiving the power, the rotating unit 2 drives the swing bracket 5 to perform rotatable movement on both sides of the U-shaped support seat 1. The movement of the swing bracket 5 further drives the dressing unit 6 to move, so that the dressing unit 6 can move according to a predetermined trajectory to meet the dressing needs of grinding wheels of different shapes and sizes. The diamond pen 61 in the dressing unit 6 directly dresses the grinding wheel. The diamond pen 61 is set on the threaded rod 62. The upper and lower positions of the diamond pen 61 can be accurately adjusted by rotating the scale sleeve 63. During the adjustment process, since the scale sleeve 63 and the threaded rod 62 are connected by threads, there is a thread gap. In order to eliminate the thread gap, a plurality of compression springs 66 arranged side by side are set. The compression spring 66 provides a stable preload for the scale sleeve 63 and the threaded rod 62. When the diamond pen 61 reaches the desired position and is locked, the grinding wheel can be trimmed. During the trimming process, the diamond pen 61 accurately trims the grinding wheel according to the predetermined trajectory and speed until the desired shape and accuracy are achieved. The threaded connection between the scale sleeve 63 and the threaded rod 62 adjusts the position of the diamond pen 61 by rotating the scale sleeve 63, thereby achieving precise control and rapid adjustment of the position of the diamond pen 61; multiple compression springs 66 arranged side by side provide a stable pre-tightening force for the scale sleeve 63 and the threaded rod 62, thereby eliminating the thread gap and improving the accuracy of the diamond pen 61; multiple compression springs 66 arranged side by side can ensure that the pressure is evenly distributed along the circumferential direction of the scale sleeve 63 and the threaded rod 62, so that the force is evenly applied, ensuring the stability and accuracy of the diamond pen operation.

[0042] like Figure 4 As shown, the inner diameter of the guide sleeve 67 is the same as that of the scale sleeve 63 , and a washer 610 is provided between the compression spring 66 and the fixing nut 65 .

[0043] Specifically, the locking nut 65 is locked on the scale sleeve 63, and rotates together with the locking nut 65 when the scale sleeve 63 is rotated. The guide sleeve 67 supports and guides the threaded rod 62, and the scale sleeve 63 is used to be threadedly connected with the threaded rod 62 and adjust its position. The inner hole diameters of the two are the same, which can ensure that the threaded rod 62 will not be subject to additional resistance or friction during movement, thereby maintaining the stability and accuracy of its movement and improving the overall accuracy of the trimmer. The washer 610 can ensure that the compression spring 66 can maintain a stable preload when under pressure, ensuring that the trimming unit 6 is stable and reliable in the adjusted position.

[0044] like Figure 4 As shown, the guide groove 69 is arranged along the axial direction of the threaded rod 62 , and the guide groove 69 is located on the side surface of the threaded rod 62 .

[0045] Specifically, the main function of the guide groove 69 is to guide the movement of the cylindrical pin 68, ensuring that the threaded rod 62 can only move axially but not rotate, limiting the rotational freedom of the threaded rod 62 and allowing it to only move linearly along the axial direction. By setting the guide groove 69 on the side surface of the threaded rod 62, it can be easily matched with the cylindrical pin 68 to achieve precise guiding and positioning functions and improve the finishing accuracy.

[0046] like Figure 3 As shown, the driving unit 4 includes a servo motor 41 , the servo motor 41 is connected to a reducer 42 , and the reducer 42 is connected to the transmission unit 3 via a coupling 43 .

[0047] Specifically, the servo motor 41 is used as a power source, and its output shaft is connected to the input shaft of the reducer 42. The output shaft of the reducer 42 is connected to the input shaft of the transmission unit 3 through the coupling 43. The coupling 43 ensures the smooth and accurate transmission of torque between the two. The driving force of the servo motor 41 is transmitted to the transmission unit 3 through the coupling 43 after being decelerated and torque-increased by the reducer 42, thereby driving the entire servo circular grinding wheel dresser to work.

[0048] like Figure 3 As shown, the rotary unit 2 includes a rotary shaft 21 , and a bearing 22 is provided on the rotary shaft 21 .

[0049] Specifically, when the external power drives the rotary shaft 21 to rotate, the bearing 22 can ensure that the rotary shaft 21 maintains a smooth and precise motion trajectory during the rotation process, thereby meeting the requirements of the servo circular grinding wheel dresser for rotation angle and accuracy during operation.

[0050] like Figure 3 As shown, the transmission unit 3 includes a driving pulley 31 , a driven pulley 32 , and a conveyor belt 33 . The driving pulley 31 is connected to the coupling 43 , and the driven pulley 32 is connected to the rotary shaft 21 .

[0051] Specifically, the transmission unit 3 is composed of a driving pulley 31, a driven pulley 32, and a conveyor belt 33 that surrounds the two. The driving pulley 31 is closely connected to the driving unit 4 through a coupling 43. The conveyor belt 33, as a medium for transmitting power, transmits the rotational power of the driving pulley 31 to the driven pulley 32. The rotation of the driven pulley 32 drives the rotation of the rotating shaft 21 connected thereto, thereby realizing the transmission of power and the driving of the rotating shaft 21. A protective cover 31 is arranged on the outside of the transmission unit 3 to play a protective role.

[0052] like Figure 2 As shown, a support box 13 is provided below the U-shaped support seat 1 , and the driving unit 4 is placed in the support box 13 .

[0053] Specifically, a support box 13 is provided below the U-shaped support base 1 to play a role of stability and support. Placing the drive unit 4 in the support box 13 not only effectively protects the drive unit 4, but also makes the entire device compact and stable.

[0054] Compared with the prior art, the beneficial effects of this application are:

[0055] The present application discloses a method for ensuring the accuracy of a grinding wheel dresser, wherein the dresser is provided with a U-shaped supporting seat 1, and a first supporting circular hole 11 and a second supporting circular hole 12 are respectively provided on both sides of the U-shaped supporting seat 1. During processing, the inner diameter of the first supporting circular hole 11 is made smaller than the inner diameter of the second supporting circular hole 12; a steel shaft is taken, and the diameter of the steel shaft is the same as the inner diameter of the first supporting circular hole 11; the steel shaft is inserted into the first supporting circular hole 11 and the second supporting circular hole 12, and a release agent is applied to the end of the steel shaft close to the second supporting circular hole 12; the U-shaped supporting seat 1 with the steel shaft inserted is placed vertically, so that one side of the first supporting circular hole 11 is located above the second supporting circular hole 12. Since the inner diameter of the first supporting circular hole 11 is the same as the diameter of the steel shaft, the first supporting circular hole 12 The inner diameter of 11 is smaller than the inner diameter of the second supporting circular hole 12. Therefore, there will be a gap between the second supporting circular hole 12 and the steel shaft. High-strength glue is filled into the gap between the steel shaft and the second supporting circular hole 12. After the glue solidifies, the steel shaft is taken out. At this time, the coaxiality of the first supporting circular hole 11 and the second supporting circular hole 12 is relatively high. Due to the fixing effect of the glue and the calibration effect of the steel shaft, the coaxiality of the first supporting circular hole 11 and the second supporting circular hole 12 has reached a relatively high precision. By using the steel shaft for calibration, the accuracy of the dresser can be significantly improved, so that it can meet the needs of high-precision processing; the method of using a steel shaft and filling with high-strength glue is relatively simple and low-cost, avoiding complex machining processes, thereby reducing production costs and time.

[0056] The position of the diamond pen 61 is adjusted by rotating the scale sleeve 63, thereby achieving precise control and rapid adjustment of the position of the diamond pen 61; multiple compression springs 66 arranged side by side provide a stable pre-tightening force for the scale sleeve 63 and the threaded rod 62, thereby eliminating the thread gap and improving the accuracy of the diamond pen 61; multiple compression springs 66 arranged side by side can ensure that the pressure is evenly distributed along the circumferential direction of the scale sleeve 63 and the threaded rod 62, so that the force is evenly distributed, thereby ensuring the stability and accuracy of the diamond pen operation.
