[0028] In grinding processing, the surface state of the grinding wheel as important grinding tool directly influences the precision and surface quality of the workpiece.With the growth of using time, the surface of the grinding wheel will gradually wear or appear deformation, so it needs to be dressed regularly.The traditional grinding wheel dressing method adopts single and sequential polishing to the two surfaces of the grinding wheel, and the efficiency is low and the dressing precision is difficult to guarantee.

[0029] Therefore, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the utility model provides a grinding wheel dressing machine, and the grinding wheel dressing machine mainly includes base 100, clamping mechanism 200 and dressing mechanism 300.The clamping mechanism 200 is connected to the base 100 and is used for clamping the grinding wheel 500 to be dressed.The clamping mechanism 200 includes base 210 and clamping assembly 220.The base 210 is provided with turntable 230 and first driving part 240 for driving the rotation of the turntable 230.The clamping assembly 220 is connected to the turntable 230 and rotates with the rotation of the turntable 230.The grinding wheel 500 to be dressed is clamped on the clamping assembly 220, thereby rotating under the driving of the turntable 230.

[0030] The trimming mechanism 300 is connected to the machine base 100 and is used to trim the rotating grinding wheel 500. The trimming mechanism 300 includes two sets of trimming assemblies 310 and two sets of driving assemblies 320 arranged on both sides of the clamping mechanism 200. Specifically, each set of trimming assemblies 310 is provided with one grinding disc 311, and the two grinding discs 311 are arranged on both sides of the grinding wheel 500 to be trimmed. In this way, when the grinding wheel 500 to be trimmed rotates, the two grinding discs 311 can simultaneously process both sides of the grinding wheel. Each set of driving assemblies 320 is connected to the bottom of one set of trimming assemblies 310. The driving assembly 320 includes a Y-axis linear guide rail 321 and an X-axis linear guide rail 322 connected to the Y-axis linear guide rail 321. The trimming assembly 310 is connected to the X-axis linear guide rail 322. Through the driving of the driving assembly 320, the trimming assembly 310 can move along the X-axis direction to approach or move away from the clamping mechanism 200. At the same time, due to the arrangement of the Y-axis linear guide rail 321, the trimming assembly 310 can also move along the Y-axis direction, so as to adjust the relative position between the two grinding discs 311 and the grinding wheel 500 to be trimmed.

[0031] In a specific embodiment, first, the grinding wheel 500 to be trimmed is clamped on the clamping assembly 220. Then, the first driving member 240 is started to drive the rotating disc 230 to rotate the clamping assembly 220 and the grinding wheel 500 to be trimmed. Next, the positions of the two trimming assemblies 310 are adjusted by the driving assembly 320, so that the two grinding discs 311 respectively approach both sides of the grinding wheel 500 to be trimmed. Finally, the grinding disc 311 driving device in the trimming assembly 310 is started to trim the rotating grinding wheel 500 to be trimmed by the grinding disc 311. Since the two grinding discs 311 are arranged on both sides of the grinding wheel 500 to be trimmed and can simultaneously process the grinding wheel, the trimming efficiency is greatly improved. At the same time, by adjusting the position and speed of the driving assembly 320, precise control of the trimming process can also be realized. By simultaneously arranging two grinding discs 311 to process both sides of the grinding wheel, the trimming efficiency is significantly improved. Compared with the traditional single-sided trimming method, the present application can save a lot of time and labor cost. Since the two grinding discs 311 can simultaneously trim both sides of the grinding wheel, it can be ensured that both sides of the grinding wheel have consistent accuracy and surface quality after trimming. This helps to improve the accuracy and surface quality of the subsequent machined parts. Furthermore, the grinding wheel trimming machine precisely controls the position and speed of the trimming assembly 310 through the driving assembly 320, so that the trimming process is more stable and reliable. At the same time, the operation interface is simple and intuitive, which is convenient for operators to operate and monitor. Further, by adjusting the position and angle of the clamping assembly 220 and the trimming assembly 310, the trimming requirements of different types of grinding wheels can be met.

[0032] Reference Figure 1 and Figure 2, two driving assemblies 320 are arranged in staggered manner along the X-axis direction. One driving assembly 320 is close to the rear end of the clamping mechanism 200, and the other driving assembly 320 is close to the front end of the clamping mechanism 200. This arrangement makes the two dressing assemblies 310 also arranged in staggered manner, and the two grinding discs 311 are arranged on the two surfaces of the dressing wheel 500, so as to better adapt to the shape and size of the dressing wheel, and ensure the uniformity and precision of dressing. Through staggered arrangement, the two grinding discs 311 can better cover the two surfaces of the dressing wheel, ensuring the uniformity and consistency of dressing.

[0033] Referring to Figure 2 In some embodiments, the bottom of the X-axis linear guide rail 322 is provided with a support plate 323, and the bottom of the support plate 323 is provided with a sliding block clamping the Y-axis linear guide rail 321. The bottom of the dressing assembly 310 is provided with a sliding block clamping the X-axis linear guide rail 322. This structure makes the dressing assembly 310 flexible in the X-axis and Y-axis directions, realizing accurate dressing control. Through the close cooperation of the sliding block and the guide rail, the stability and precision of the dressing assembly 310 during movement are ensured.

[0034] Further, the driving assembly 320 further comprises a lead screw 324, a lead screw 324 seat and a second driving member 325 connected and driving the lead screw 324 to rotate. The support plate 323 and the dressing assembly 310 are respectively connected to the lead screw 324 seat to be driven by the second driving member 325 to move linearly. This driving mode can realize accurate displacement control and improve dressing precision. Through the driving of the lead screw 324, accurate positioning and control of the dressing assembly 310 can be realized.

[0035] Referring to Figure 2 and Figure 3 The dressing assembly 310 comprises a housing 312 and a third driving member 313 arranged in the housing 312.

The housing 312 is further connected with a baffle 314, which is in semicircular arc shape and is arranged adjacent to the grinding disc 311. This structure can prevent the debris generated during dressing from splashing, protecting the machine and the operator.

[0036] Referring to Figure 4 and Figure 5Specifically, the bottom of the base 210 has a cavity 211, and the bottom of the rotating disc 230 is provided with a driven wheel 231 extending into the cavity 211. The first driving member 240 is connected with a driving wheel 241 located in the cavity 211, and the driving wheel 241 is connected with the driven wheel 231 through a belt 242. This driving mode is simple in structure and convenient to maintain. Further, a limiting plate 250 is arranged in the cavity 211 and located below the driving wheel 241. The limiting plate 250 is provided with a limiting hole 251 extending therethrough, and the driven wheel 231 is provided with a limiting rod 232 extending downward and inserted into the limiting hole 251. This structure can limit the axial movement of the rotating disc 230 and improve the stability of the machine. The cooperation of the limiting plate 250 and the limiting rod 232 can prevent the rotating disc 230 from moving in the axial direction and improve the stability of the machine.

[0037] With reference to Figure 5 It should be noted that the clamping mechanism 200 further comprises a pressing assembly 260. The pressing assembly 260 is connected to the clamping assembly 220 and comprises a box body 261 and a pressing rod 262 connected to the box body 261. The box body 261 is integrally arranged with the clamping assembly 220, and the clamping assembly 220 has a clamping head 221 for clamping the grinding wheel 500 to be dressed. The axis of the pressing rod 262 is perpendicular to the end face of the clamping head 221, and the pressing rod 262 is tapered towards the side close to the clamping head 221. This structure can ensure that the grinding wheel remains stable during dressing. The pressing assembly 260 can ensure that the grinding wheel does not fall off or shift due to vibration during dressing. The tapered pressing rod 262 makes the pressing process easier and faster.

[0038] Further, the pressing rod 262 is slidingly connected to the box body 261, and the box body 261 is provided with an adjusting hand wheel 263. The adjusting hand wheel 263 is connected and drives the pressing rod 262 to move towards or away from the clamping head 221. This structure enables the operator to adjust the size of the pressing force as needed. The operator only needs to rotate the adjusting hand wheel 263 to achieve the adjustment of the pressing force. In other embodiments, the pressing rod 262 can also be driven to move automatically by a motor, air cylinder, etc., instead of manual operation.

[0039] With reference to Figure 6It should be noted that the grinding wheel dresser further comprises a cooling mechanism 400. The cooling mechanism 400 comprises a water tank 410 and liquid outlets 420, and the two liquid outlets 420 are arranged to contact the two grinding discs 311 and the grinding wheel 500 to be dressed respectively. The liquid outlets 420 are connected to the water tank 410 through water pipes, and the base is provided with a liquid discharge groove 110 which is communicated with the water tank 410. This structure can ensure that the temperature of the grinding disc 311 and the grinding wheel during dressing is maintained within a reasonable range, thereby improving the dressing quality and the service life of the machine. The cooling mechanism 400 can reduce the temperature of the grinding disc 311 and the grinding wheel, prevent the dressing quality from being reduced due to overheating, the two liquid outlets 420 can ensure the cooling effect when the two dressing assemblies 310 are simultaneously processed, and the cooling liquid can be recycled through the liquid discharge groove 110, thereby reducing the pollution to the environment and reducing the use cost.
