Description

Technical Field

[0001] This invention relates to a grinding wheel alignment device for a grinding machine, specifically a technology applied in the field of machining. Its main purpose is to improve the accuracy of grinding wheel rotation in grinding machines, and to ensure the precision of grinding wheel grinding with appropriate counterweights. It is an invention with excellent practicality. Background Technology

[0002] In today's technologically advanced era of numerous processing machines, grinding machines are undoubtedly used for polishing and grinding operations. The core of the entire processing machine is the grinding wheel. During the operation of the grinding machine, in order to prevent the grinding wheel from easily shifting under high-speed rotation, a counterweight is usually installed at the position where the grinding wheel is mounted. The purpose of the counterweight is to ensure that the grinding wheel rotates evenly under high-speed rotation, so that the grinding wheel can grind the workpiece evenly and avoid uneven grinding caused by the grinding wheel shifting under high-speed rotation.

[0003] However, the above process presents a major problem for grinding machines today: the placement of the counterweights. In the past, the placement of counterweights required repeated manual attempts to match the weights. Each attempt required the grinding wheel to rotate at high speed for a period of time and several samples to be ground and tested. Finally, the size and proportion of the samples were checked to see if they met the specifications. Only after repeated testing could the weight configuration of the counterweights be confirmed. This method is not only too time-consuming, but also relies heavily on experience and skill for the precision required in grinding. This makes it impossible for novice operators to accurately select the counterweights. If the selection of counterweights is inaccurate, the subsequent grinding of the items will not be as precise.

[0004] In view of the problems with the existing grinding machine's method of placing counterweights as described in the prior art above, the inventors have devoted a lot of time to studying the relevant knowledge, comparing the advantages and disadvantages of various methods, conducting research and development of related products, and undergoing numerous experiments and tests. Finally, they have launched a "grinding wheel alignment device for grinding machines" to improve the above-mentioned deficiencies and meet the needs of the public. Summary of the Invention

[0005] To address the issue that existing grinding machines require repeated and time-consuming attempts to place the counterweights, and that the placement of the counterweights determines the accuracy of the grinding wheel's application, while current methods rely heavily on experience and skill, making it difficult for novice operators to immediately determine the appropriate counterweight ratio, thus leading to significant errors in grinding during high-speed rotation, this invention provides a grinding wheel calibration device for grinding machines. This device allows for quick, precise, and accurate placement of the optimal counterweight before grinding, ensuring high precision and minimizing grinding errors during subsequent high-speed rotation.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A grinding wheel alignment device for a grinding machine includes: a grinding machine body comprising a man-machine section and a grinding wheel working section, the grinding wheel working section having a mounting shaft, the man-machine section driving the mounting shaft to rotate; a grinding wheel mounted on the grinding wheel working section and sleeved on the mounting shaft, the mounting shaft driving the grinding wheel to rotate; a counterweight plate mounted on the grinding wheel working section and sleeved on the mounting shaft, the counterweight plate being positioned closer to the end of the mounting shaft than the grinding wheel, and the side of the counterweight plate facing the end of the mounting shaft further having a gauge section and an annular groove; several counterweight blocks mounted within the annular groove; a speed sensor and... A vibration detector is mounted on the mounting shaft and electrically connected to the human-machine interface. The speed detector detects the rotational speed of the grinding wheel, while the vibration detector detects the vibration value of the mounting shaft at any rotational speed range of the grinding wheel. The human-machine interface further includes a receiving unit, a data generation unit, and a database. The receiving unit receives data from the speed detector and the vibration detector, the database stores comparison data, and the data generation unit compares the data received by the receiving unit with the comparison data in the database to generate a data display value corresponding to the weight of the counterweights. This data display value is displayed on the human-machine interface.

[0008] When the mounting shaft is not yet fitted with the counterweights in the annular groove of the counterweight disc, the human-machine interface drives the mounting shaft to rotate the grinding wheel. The speed sensor and the vibration sensor detect the rotational speed of the grinding wheel and the vibration of the mounting shaft, respectively. After detection, the data is transmitted to the receiving unit in the human-machine interface. At the same time, the data generation unit compares the data received by the receiving unit with the comparison data in the database. After the comparison is completed, the data generation unit generates the data display value, which can be used as a reference to quickly retrieve the corresponding counterweight.

[0009] A further technical feature of the present invention is that the human-machine interface further includes a configuration display unit, which corresponds to the ruler section and the annular groove section of the counterweight plate. The configuration display unit displays the position of each counterweight block installed in the annular groove section, as well as the dimensional position of each counterweight block corresponding to the ruler section.

[0010] A further technical feature of the present invention is that the human-machine interface further incorporates a debugging unit. After each counterweight is installed in the ring groove and the operation of the grinding wheel is started, the debugging unit provides a reminder when the data generation unit generates data showing abnormal values. The debugging unit displays an error reminder in the human-machine interface.

[0011] A further technical feature of the present invention is that the human-machine interface further incorporates a debugging unit. After each counterweight is installed in the ring groove and the operation of the grinding wheel is started, the debugging unit will issue a reminder when the data generation unit generates data showing an abnormal value. The debugging unit will display the error location signal in the configuration display unit.

[0012] A further technical feature of the present invention is that each counterweight further penetrates a locking hole and a channel. The locking hole of each counterweight is set from the groove opening facing the bottom of the groove, while the channel of each counterweight is set from one side of the groove wall of the corresponding groove to the other side of the groove wall. In addition, several fixing locks are provided to lock the locking holes of each counterweight, and several balls are installed in each channel. When each fixing lock is locked relative to the locking hole, it abuts against each ball, preventing the ball from rolling and causing it to rub against the groove wall of the groove. When each fixing lock is loosened relative to the locking hole, the ball loses the abutment of the fixing lock and rolls freely in the channel, allowing each counterweight to move and adjust its position within the groove.

[0013] A further technical feature of the present invention is that a number of locking fasteners are inserted into a number of screw holes in the ruler part and locked to the mounting shaft. The ruler part has a size diagram on its outer surface, and each counterweight can be adjusted in position within the ring groove according to the size diagram.

[0014] A further technical feature of the present invention is that a nozzle is further installed on the outer periphery of the grinding wheel working part. One end of the nozzle faces the grinding wheel, and the other end of the nozzle is connected to an air valve. The air valve is connected to an air supply component. When the air valve is opened, the gas from the air supply component flows through the nozzle and is sprayed toward the grinding wheel. When the air valve is closed, the flow between the air supply component and the nozzle is interrupted.

[0015] The beneficial effect of this invention is that, in the calibration of the grinding wheel before operation, the grinding machine can quickly, accurately and precisely place the optimal counterweight, so that the grinding wheel can achieve high precision in grinding the workpiece under subsequent high-speed rotation, and minimize the grinding error.

[0052] To clearly illustrate the aforementioned objectives and effects achieved by the present invention, its features and effects will be described in detail below with reference to the accompanying drawings and embodiments. Please refer to... Figures 1 to 5As shown, the present invention discloses a grinding wheel alignment device for a grinding machine, comprising: a grinding machine body 10, including a man-machine section 101 and a grinding wheel working section 102, the grinding wheel working section 102 having a mounting shaft 20, the man-machine section 101 driving the mounting shaft 20 to rotate; a grinding wheel 30, mounted on the grinding wheel working section 102 and sleeved on the mounting shaft 20, the mounting shaft 20 driving the grinding wheel 30 to rotate; and a counterweight disc 40, which is disc-shaped, mounted on the grinding wheel working section 102 and sleeved on the mounting shaft 20, the mounting position of the counterweight disc 40 being closer to the mounting shaft 20 than the grinding wheel 30. At the end, the counterweight plate 40, facing the end of the mounting shaft 20, is further provided with a ruler portion 401 and an annular groove portion 402; several counterweight blocks 50 are installed in the annular groove portion 402, and each counterweight block 50 is stably set and eliminates the wobble and shaking generated by the grinding wheel 30 during operation; a speed sensor 60 and a vibration sensor 70 are both electrically connected to the human-machine interface 101 and are installed on the mounting shaft 20. The speed sensor 60 detects the rotational speed of the grinding wheel 30, while the vibration sensor 70 detects the vibration value of the mounting shaft 20 in any rotational speed range of the grinding wheel 30. The human-machine interface 101 is further provided with a ruler portion 401 and an annular groove portion 402; several counterweight blocks 50 are installed in the annular groove portion 402, and each counterweight block 50 is stably set and eliminates the wobble and shaking generated by the grinding wheel 30 during operation; a speed sensor 60 and a vibration sensor 70 are both electrically connected to the human-machine interface 101 and are installed on the mounting shaft 20. The speed sensor 60 detects the rotational speed of the grinding wheel 30, while the vibration sensor 70 detects the vibration value of the mounting shaft 20 in any rotational speed range of the grinding wheel 30. A receiving unit 103, a data generation unit 104, and a database 105 are constructed. The receiving unit 103 receives data from the speed sensor 60 and the vibration sensor 70. The database 105 stores comparison data 106. The data generation unit 104 compares the data received by the receiving unit 103 with the comparison data in the database 105 to generate a data display value 107 corresponding to the weight of the counterweights 50. The data display value 107 is displayed on the human-machine interface 101. The mounting shaft 20 is not yet fitted with the counterweights in the annular groove 402 of the counterweight plate 40. When the counterweight 50 is being retrieved, the human-machine interface 101 drives the mounting shaft 20 to rotate the grinding wheel 30. The speed sensor 60 and the vibration sensor 70 detect the rotational speed of the grinding wheel 30 and the vibration of the mounting shaft 20, respectively. After detection, the data is transmitted to the receiving unit 103 in the human-machine interface 101. At the same time, the data generation unit 104 compares the data received by the receiving unit 103 with the comparison data in the database 105. After the comparison is completed, the data generation unit 104 generates the data display value 107, which can be used as a reference to quickly retrieve the corresponding counterweight 50.

[0053] Based on the above basic description of the present invention, the operator only needs to perform two simple steps. First, after installing the grinding wheel 30 and the counterweight plate 40 onto the mounting shaft 20, the human-machine interface 101 is started. At this time, the speed sensor 60 and the vibration sensor 70 will detect the grinding wheel 30 before the counterweights 50 are installed, detecting the rotational speed of the grinding wheel 30 and the vibration amplitude transmitted to the mounting shaft 20 when the grinding wheel 30 is operating. After detection, the relevant data is transmitted to the receiving unit 103 of the human-machine interface 101. At this time, the data generation unit 104 built into the human-machine interface 101 will compare the information received by the receiving unit 103 with the comparison data in the database 105. After comparison, the data generation unit 104 will convert the comparison data into relevant digital information. This digital information corresponds to the weight and installation position of each counterweight 50, so that the operator can use the data to determine the correct location. The information generated by the generation unit 104 selects the corresponding weight of the counterweight 50 and adjusts the distribution position of each counterweight 50 in the annular groove 402. After the installation of each counterweight 50 is completed, the grinding wheel 30 can be operated again to check whether the position and weight of the installed counterweight 50 are correct. If there are no errors, the grinding operation of the production line can be carried out directly to grind items with consistent size and specifications. Afterwards, the operator can also check the data displayed on the human machine unit 101 at any time through the sensing of the speed sensor 60 and the vibration sensor 70 to correct the position and weight of each counterweight 50 at any time. In addition, in addition to the aforementioned location on the mounting shaft 20, the speed sensor 60 can also be set at the drive motor in the grinding wheel working part 102 (not shown). Since the drive motor is the main power source for driving the operation of the mounting shaft 20, the speed sensor 60 can also be installed on the drive motor to detect the rotation speed.

[0054] Based on the above description of the present invention, other technical features of the present invention will now be further detailed below. First, please see Figure 4As shown, to facilitate the operator's installation of each counterweight 50 and to avoid errors in the installation position of each counterweight 50, a configuration display unit 108 is further built into the human-machine interface 101. This configuration display unit 108 corresponds to the ruler section 401 and the annular groove section 402 of the counterweight plate 40. The configuration display unit 108 displays the position of each counterweight 50 installed in the annular groove section 402. Several locking fasteners 80 are inserted into several screw holes 403 of the ruler section 401 and locked to the counterweight plate 40. A size chart 404 is provided on the outer surface of the ruler section 401, allowing each counterweight 50 to be installed according to its size. The size chart 404 is adjusted to be positioned within the annular groove 402, meaning that the ruler section 401 can be replaced with size charts 404 of different sizes and proportions, thereby matching counterweights 50 of different lengths. The configuration display unit 108 of the human-machine interface 101 allows the operator to directly view the position of each counterweight 50 and make detailed comparisons and adjustments with the size chart 404 on the ruler section 401, making the installation position of each counterweight 50 more accurate. The operator only needs to select and install the counterweights 50 according to the display unit 108, reducing errors that may affect the grinding operation of the grinding wheel 30.

[0055] Furthermore, to prevent operator errors from affecting the grinding operation, a debugging unit 109 is further integrated into the human-machine interface 101. This debugging unit 109 is installed on each counterweight 50 in the ring groove 402. After the grinding wheel 30 is started, the debugging unit 109 provides an alert when the data generation unit 104 generates an abnormal data display value 107. The debugging unit 109 displays the error alert on the human-machine interface 101, and the error alert on the human-machine interface 101 is displayed as an error location signal in the configuration display unit 108, such as... Figure 4 , Figure 5 As shown, when the grinding wheel 30 is running at high speed, the data sensed by the speed sensor 60 and the vibration sensor 70 is received by the receiving unit 103. After a series of comparisons, if the generated data value 107 is too abnormal, the debugging unit 109 will flash or turn red at the position of each counterweight 50 on the configuration display unit 108 to remind the operator to check whether there are any problems such as incorrect installation or incompleteness at the display error position. The setting of the debugging unit 109 is like setting up a safety net to avoid all items being out of compliance with specifications after grinding, resulting in excessive cost expenditure and waste of materials.

[0056] Continuing from the foregoing description, in order to prevent the counterweights 50 from being thrown off their original positions under the high-speed operation of the mounting shaft 20, each counterweight 50 is further provided with a locking hole 501 and a channel 502. The locking hole 501 of each counterweight 50 is set from the opening of the annular groove 402 toward the bottom of the groove, while the channel 502 of each counterweight 50 is set from one side of the groove wall of the corresponding annular groove 402 toward the other side of the groove wall. In addition, several fixing locks 90 are provided to lock into the locking holes 50 of each counterweight 50. 1. Several additional beads 91 are installed in each channel 502. When each fixing lock 90 is locked relative to the lock hole 501, it abuts against each bead 91, preventing the beads 91 from rolling and causing them to rub against the groove wall of the annular groove. This prevents the counterweights 50 from being thrown off and changing position when the counterweight disc 40 rotates at high speed. When each fixing lock 90 is loosened relative to the lock hole 501, each bead 91 loses the abutment of the fixing lock 90 and rolls freely within the channel 502. The counterweights 50 can then move and adjust their position within the annular groove 402. Please see [link to documentation]. Figure 2A and Figure 3 As shown.

[0057] Finally, to keep the grinding wheel 30 clean during the grinding process and prevent dust from adhering to it and affecting grinding, a nozzle 110 is further installed on the outer periphery of the grinding wheel working part 102. One end of the nozzle 110 faces the grinding wheel 30, and the other end is connected to an air valve 111. The air valve 111 is connected to an air supply assembly 112. Opening the air valve 111 allows gas from the air supply assembly 112 to flow through the nozzle 110. The air supply component 112 and the nozzle 110 are used to spray air onto the grinding wheel 30. Closing the air valve 111 interrupts the flow between the air supply component 112 and the nozzle 110. The operator only needs to open the air supply component 112 and the air valve 111 during the grinding process, using the nozzle 110 to spray air onto the grinding wheel 30 and the workpiece. This keeps the grinding wheel 30 clean. Furthermore, the nozzle 110 uses a conical tube, allowing the operator to freely adjust the position of the nozzle 110 spraying air onto the grinding wheel 30. Please see [link to documentation]. Figure 2 As shown.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
