[0044] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0045] The core of the present utility model is to provide an automatic grinding wheel dressing device, which can realize automatic dressing of the grinding wheel, thereby improving the dressing efficiency of the grinding wheel and further improving the machining efficiency of workpieces.

[0046] It should be noted that in this embodiment, the orientation or positional relationship indicated by "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0047] Please refer to Figures 2 - 4The present application provides an automatic grinding wheel dressing device, including a support seat 1, a first driver 11, a slide seat 2, a second driver 21, a dressing disk 22, a position sensor and a dressing disk 22.

[0048] The first driver 11 and the slide 2 are both disposed on the support base 1 , and the output shaft of the first driver 11 is connected to the slide 2 for driving the slide 2 to slide on the support base 1 along the front-rear direction.

[0049] The second driver 21 and the trimming disk 22 are both disposed on the slide 2 , and the output shaft of the second driver 21 is connected to the trimming disk 22 via a transmission structure 23 , so as to drive the trimming disk 22 to rotate.

[0050] The controller is electrically connected to the position sensor, the first driver 11 and the second driver 21 . The position sensor is used to measure the horizontal distance between the dressing disc 22 and the grinding wheel 5 and transmit it to the controller. The controller is used to receive the horizontal distance and control the extension stroke of the output shaft of the first driver 11 .

[0051] It should be noted that the automatic grinding wheel dressing device of the present application is applied to the dressing operation of the grinding wheel 5 of the grinding machine. The grinding machine generally includes a grinding wheel 5, a grinding wheel 5 lifting drive device and a grinding wheel rotation drive device 6. The grinding wheel 5 and the grinding wheel rotation drive device 6 are arranged on a slide plate 7. The slide plate 7 is connected to the driving end of the grinding wheel 5 lifting drive device to drive the grinding wheel 5 and the grinding wheel 5 lifting drive device to move up and down through the slide plate 7. The driving end of the grinding wheel 5 lifting drive device is connected to the grinding wheel 5 to drive the grinding wheel 5 to rotate. Figure 1 However, the arrangement of the device for driving the grinding wheel 5 to rise and fall and rotate is not unique, and other arrangements may be adopted with reference to existing grinding machines, as long as the grinding wheel 5 can be driven to rise and fall and rotate. In addition, when grinding the grinding wheel 5, the dressing disc 22 rotates in the opposite direction to the grinding wheel 5, so that the grinding wheel 5 can be ground by a pair of reverse forces generated therebetween, and the surface of the grinding wheel 5 can regain a higher grinding grain size.

[0052] The first driver 11 can be an air cylinder, an oil cylinder or an electric cylinder, and the type is not unique, as long as it can drive the slide 2 to slide back and forth; the second driver 21 can be an efficient motor 211 and a reducer 212, the reducer 212 is connected to the rotating shaft of the motor 211, and the output shaft of the reducer 212 is connected to the dressing disk 22 through the transmission structure 23.

[0053] The position sensor is not limited to non-contact sensors such as photoelectric sensors and capacitive sensors. It is preferably arranged on the dressing disk 22. A sensing sheet that senses the position sensor is arranged on the grinding wheel 5. The transmitting end of the position sensor cooperates with the sensing sheet to measure the horizontal distance between the dressing disk 22 and the grinding wheel 5.

[0054] In this way, when the above-mentioned grinding wheel automatic dressing device is in use, the position sensor detects the horizontal distance between the dressing disc 22 and the grinding wheel 5 and transmits it to the controller. The controller controls the output shaft of the first driver 11 to extend forward by the obtained horizontal distance value. The slide seat 2 drives the dressing disc 22 to move forward and accurately positions the dressing disc 22 below the grinding wheel 5, as Figure 1 shown. Then, the second driver 21 drives the dressing disc 22 to rotate through the transmission structure 23. The grinding wheel 5 of the grinding machine descends to contact the dressing disc 22, and the grinding wheel 5 rotates. The surface of the grinding wheel 5 regains a higher grinding grain size, and the grinding wheel 5 is dressed. Therefore, the present application can achieve the accurate positioning and self-rotation of the dressing disc 22 to realize the automatic dressing of the grinding wheel 5, thereby improving the dressing efficiency of the grinding wheel 5 and further improving the workpiece processing efficiency.

[0055] In addition, the present application can control the extension stroke of the output shaft of the first driver 11 by the controller, and also control the rotation start and stop of the output shaft of the second driver 21. Therefore, the return stroke and stop time of the dressing disc 22 can be controlled to ensure that the dressing time and dressing cycle of the grinding wheel 5 are controllable each time, so as to detect and intervene in a timely manner for the dressing of the grinding wheel 5 topography according to different workpiece processing processes.

[0056] Considering the specific structure and installation method of the slide seat 2, on the basis of the above-mentioned embodiment, please refer to Figure 3 and Figure 4 , the slide seat 2 is of a box structure. The side part of the slide seat 2 is slidably connected to the support seat 1. The second driver 21 is fixed to the bottom of the slide seat 2 through the mounting plate 24, and its output shaft passes through the slide seat 2 and is connected to a transmission part of the transmission structure 23 placed inside the slide seat 2. The other transmission part of the transmission structure 23 is connected to the dressing disc 22 placed on the top of the slide seat 2.

[0057] Specifically, the slide seat 2 is placed on the support seat 1 so as to be slidable back and forth. The speed reducer 212 is connected to the rotating shaft of the motor 211. The speed reducer 212 is fixed to the bottom of the slide seat 2 through the mounting plate 24, and its output shaft passes through the bottom wall of the slide seat 2 and extends into its internal space. The transmission structure 23 is placed in the internal space of the slide seat 2. The dressing disc 22 is arranged on the top of the slide seat 2. The two transmission parts of the transmission structure 23 are respectively connected to the output shaft of the speed reducer 212 and the dressing disc 22 to transmit the driving force of the second driver 21 to the dressing disc 22 and drive the dressing disc 22 to rotate.

[0058] As can be seen from the above, with the slide seat 2 arranged as above, not only can the second driver 21 and the dressing disc 22 be firmly supported to ensure the structural stability of the second driver 21 and the dressing disc 22, but also the box structure is reasonably utilized to accommodate the transmission structure 23 to protect the transmission structure 23 from external impacts and vibrations, and the service life of the transmission structure 23 is improved.

[0059] Considering the specific installation method of the dressing disc 22, on the basis of the above-mentioned embodiment, please refer toFigure 3 and Figure 4 The dressing disc 22 is fixed to the slide block 2 through the mounting seat 25. One end of the mounting seat 25 facing away from the dressing disc 22 passes through the slide block 2 and is connected to the other transmission part of the transmission structure 23, so that the dressing disc 22 is firmly mounted on the top of the slide block 2, and the dressing disc 22 is in transmission connection with the transmission structure 23 placed inside the slide block 2 without damaging the structure of the dressing disc 22, thereby ensuring the smooth rotation of the dressing disc 22.

[0060] Considering the specific structure and installation method of the transmission structure 23, on the basis of the above embodiments, please refer to Figure 4 As shown in Figure 4 , the transmission structure 23 includes a first synchronous pulley 231, a second synchronous pulley 232 and a synchronous belt 233. The first synchronous pulley 231 is sleeved on the output shaft of the second driver 21, the second synchronous pulley 232 is sleeved on the mounting seat 25, and the synchronous belt 233 is connected between the first synchronous pulley 231 and the second synchronous pulley 232. Therefore, by using the synchronous belt 233 wheel structure to connect the second driver 21 and the dressing disc 22, the driving force of the second driver 21 can be accurately, efficiently and smoothly transmitted to the dressing disc 22.

[0061] Considering the specific structure of the support seat 1, on the basis of the above embodiments, please refer to Figure 3 As shown in Figure 3 , the support seat 1 is in an inverted U shape. The first driver 11 is fixed to the top plate of the support seat 1, and the slide block 2 can slide back and forth in the space between the two side plates of the support seat 1.

[0062] It can be understood that the two side plates and the top plate placed at their tops can form an inverted U-shaped support seat 1. This support seat 1 not only has good load-bearing capacity to ensure the structural stability of the first driver 11 and the slide block 2, but also has a certain vertical accommodation space, so that the slide block 2 can be placed in the accommodation space, that is, the slide block 2 is located below the top plate and is slidably connected to the two side plates. At the same time, the first driver 11 is placed on the top plate, so that the first driver 11 and the slide block 2 are arranged in sequence from top to bottom, which not only ensures the structural stability of the first driver 11 and the slide block 2, but also makes the first driver 11 and the slide block 2 be compactly arranged.

[0063] Preferably, please refer to Figure 5 As shown in Figure 5 , a pair of slide rails 12 are symmetrically arranged on the two side plates of the support seat 1, and a pair of sliders 27 are symmetrically arranged on the two sides of the slide block 2. The sliders 27 are slidably placed in the slide rails 12 one by one, which can prevent the slide block 2 from tilting during the sliding process, thereby ensuring the smooth sliding of the slide block 2.

[0064] Considering the specific connection method between the first driver 11 and the dressing disc 22, on the basis of the above embodiments, please refer to Figure 3, a dressing disk 22 is arranged at the front end of the sliding seat 2. A vertical connecting plate 26 is arranged at a position of the sliding seat 2 adjacent to the dressing disk 22. The output shaft of the first driver 11 is connected to the connecting plate 26.

[0065] Specifically, since the first driver 11 and the sliding seat 2 are arranged in sequence from top to bottom, that is, the first driver 11 is located above the sliding seat 2. The first driver 11 is fixed to the top plate of the support seat 1. A vertical connecting plate 26 is arranged on the sliding seat 2. Preferably, the first driver 11 and the connecting plate 26 are on the same horizontal plane, so that the output shaft of the first driver 11 can abut against the connecting plate 26, thereby driving the sliding seat 2 to slide back and forth. In addition, the dressing disk 22 is arranged at the front end of the sliding seat 2, and the connecting plate 26 is arranged close to the dressing disk 22, so that the part of the sliding seat 2 extending out of the support seat 1 can transmit the impact and vibration force to the first driver 11 through the connecting plate 26 in time, and the first driver 11 then transmits it to the support seat 1, improving the structural stability of the sliding seat 2.

[0066] To protect the structure from external influences, on the basis of the above embodiments, please refer to Figure 2 , this application further includes a rear outer cover 3 and a front outer cover 4; the rear outer cover 3 covers the outer periphery of the support seat 1 and the first driver 11, and is fixedly connected to the support seat 1; the front outer cover 4 covers the outer periphery of the sliding seat 2 and the second driver 21, and is detachably connected to the rear outer cover 3, and the dressing disk 22 passes through the front outer cover 4 and extends outside it.

[0067] It can be understood that the rear outer cover 3 and the front outer cover 4 are arranged in the direction from back to front, so that the rear outer cover 3 is located on the outer periphery of the first driver 11 and the support seat 1, and the front outer cover 4 is located on the outer periphery of the second driver 21 and the sliding seat 2, to protect the structure of this application from the external environment, prevent foreign objects from entering the structure, and reduce structural damage. In addition, it should be noted that the rear outer cover 3 and the front outer cover 4 are detachably connected. A perforation is provided at a position of the front outer cover 4 corresponding to the dressing disk 22, and the dressing disk 22 passes through the perforation and is placed outside the front outer cover 4. In this way, if the position of the dressing disk 22 needs to be adjusted, the front outer cover 4 that hinders the forward and backward movement of the dressing disk 22 is removed. After the dressing disk 22 is moved to the required position, the front outer cover 4 can be reinstalled to prevent abrasive dust from entering the structure and ensure the normal operation of the dressing disk 22.

[0068] Considering the specific structure of the front outer cover 4, on the basis of the above embodiments, please refer to Figure 6 and Figure 7 , the front outer cover 4 includes an upper housing 41 and a lower housing 42; the lower housing 42 is located on the outer periphery of the second driver 21 and extends forward a certain distance to form a support portion 421, and the front part of the sliding seat 2 is in sliding contact with the support portion 421; the upper housing 41 is located on the outer periphery of the sliding seat 2 and is detachably connected to the top of the lower housing 42, and the dressing disk 22 is located outside the upper housing 41.

[0069] Specifically, the front outer cover 4 is a removable upper shell 41 and a lower shell 42, the lower shell 42 is placed on the outer periphery of the second driver 21, and the upper shell 41 is placed on the outer periphery of the slide 2. In this way, if the position of the trimming disk 22 needs to be adjusted, only the upper shell 41 needs to be removed, and the front outer cover 4 does not need to be completely removed, which is convenient for adjusting the trimming disk 22, improving the extension or return efficiency of the trimming disk 22, and improving the movement efficiency of the trimming disk 22. A support seat is provided at the front of the upper shell 41, which is located in front of the second driver 21. The support seat and the inner wall of the shell around it form a support portion 421. The bottom wall of the slide 2 slides against the support seat, and the support seat plays the role of a sliding support, which can prevent the slide 2 from tilting downward after sliding a certain distance, so as to support the slide 2 to slide smoothly. It should be noted that the length of the support portion 421, that is, the support seat, needs to be set according to the slide 2 moving forward to the maximum stroke position.

[0070] Furthermore, a proximity switch electrically connected to the controller is provided at the front end of the support portion 421. The proximity switch cooperates with the slide 2 inductively. When the proximity switch senses the slide 2, a signal is sent to the controller. The controller controls the first driver 11 to stop driving, so that the slide 2 stops moving forward and prevents the slide 2 from sliding out of the support portion 421.

[0071] Optionally, the bottom end of the support base 1 is fixed on the base 8 to provide stable support for the support base 1, thereby ensuring the structural stability of the overall device.
