DETAILED DESCRIPTION

[0033] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1 - Fig.11The device for detecting the balance of a grinding wheel is shown, comprising a grinding machine body 1, a transmission shaft 21 matched with the output end of a grinding wheel motor in the grinding machine body 1, a balance detector 2 rotatably arranged outside the transmission shaft 21 and connected to the control end signal of the grinding machine body 1, and a grinding wheel 11 fixedly connected to the transmission shaft 21 and located on the left side of the balance detector 2, a dust cover 13 sleeved on the outside of the grinding wheel 11 is fixedly connected to the left end of the balance detector 2, and an axial offset sensing component 3 matched with the grinding wheel 11 is arranged on the left and right inner walls of the dust cover 13;

[0036] The axial offset sensing component 3 includes a retaining ring 31 fixedly connected to the left and right inner walls of the dust cover 13 respectively, and a flexible sleeve 32 is fixedly connected to one end of the retaining ring 31 close to the grinding wheel 11, and an axial sensing cavity is opened in the flexible sleeve 32. A plurality of rigid extrusion columns 34 are fixedly connected to the inner wall of the axial sensing cavity close to the grinding wheel 11, and a plurality of elastic pressure strips 33 corresponding to the rigid extrusion columns 34 are fixedly connected to the inner wall of the axial sensing cavity away from the grinding wheel 11, and the elastic pressure strips 33 are fixedly connected to the rigid extrusion columns 34 at corresponding positions;

[0037] The flexible sleeve 32 is fixedly connected with a linkage ring 4 on one side close to the grinding wheel 11, and the linkage ring 4 abuts against the grinding wheel 11, and the linkage ring 4 and the transmission shaft 21 are in sliding cooperation;

[0038] The balance detector 2 is equipped with a balance detection system, which includes a balance detection processing unit, the input end of which is connected to an execution instruction acquisition unit and an axial pressure acquisition unit, and the output end of which is connected to a front speed adjustment unit, a balance data output unit and a balance difference warning unit;

[0039] The input end of the execution instruction acquisition unit is connected to the control end signal of the grinding machine body 1, the input end of the axial pressure acquisition unit is connected to the axial pressure probe signal arranged in the elastic pressure strip 33, the output end of the front speed adjustment unit is connected to the grinding wheel motor signal in the grinding machine body 1, the output end of the balance data output unit is connected to the signal output port signal arranged on the balance detector 2, and the output end of the balance difference warning unit is connected to the alarm and alarm light signal arranged on the balance detector 2. Through the arrangement of the axial offset sensing component 3, the linkage ring 4 and the balance detection system, on the one hand, it can play a role in automatically detecting the balance of the grinding wheel 11, and on the other hand, it can effectively detect the balance of the grinding wheel 11. While improving the detection efficiency, it is also possible to improve the accuracy of the balance detection of the grinding wheel 11, promote the accuracy of the subsequent balance adjustment of the grinding wheel 11, and improve the stability and safety of the grinding machine body 1 during operation. On the other hand, the power of the grinding machine body 1 can be used to perform effective dynamic balancing detection on the grinding wheel 11, while reducing the detection cost and maintenance cost. It can also effectively realize the continuous detection of the balance of the grinding wheel 11 during the application process, further improve the safety of the grinding wheel 11 during the application process, improve the automation and intelligence level of the grinding machine body 1, effectively promote the application development of the grinding machine body 1, and promote the economic benefits of the grinding machine body 1.

[0040] Figure 1 - Fig.11 It is shown that the retaining ring 31 and the flexible sleeve 32 are both sleeved on the outside of the transmission shaft 21 and are rotationally matched with the transmission shaft 21. The sliding cooperation between the retaining ring 31 and the flexible sleeve 32 and the transmission shaft 21 can effectively prevent the retaining ring 31 and the flexible sleeve 32 from producing accompanying rotation, thereby realizing effective detection of changes in the axial range of the grinding wheel 11.

[0041] Figure 1 , Figure 3 and Figure 4 It is shown that the output end of the grinding wheel motor in the grinding machine body 1 is connected to a pulley transmission structure, and the right end of the transmission shaft 21 extends to the outside of the balance detector 2 and is fixedly connected to the pulley transmission structure. While ensuring the working effect and safety of the grinding machine body 1, the setting of the balance detector 2 is increased, and while improving the automation and intelligence of the grinding machine body 1, the function of automatic detection of the dynamic balance data of the grinding wheel 11 is effectively realized.

[0042] Figure 1 - Fig.11It is shown that an annular waist groove 41 is opened at the outer end of the linkage ring 4, and a radial offset sensing component 5 matching the grinding wheel 11 is arranged in the annular waist groove 41. The input end of the balance detection processing unit is also connected to a radial pressure acquisition unit, and the input end of the radial pressure acquisition unit is connected to the radial offset sensing component 5 signal. The setting of the linkage ring 4, the radial offset sensing component 5 and the radial pressure acquisition unit effectively increases the comprehensiveness of the detection data of the grinding wheel 11, further improves the accuracy of the balance detection of the grinding wheel 11, ensures the accuracy and effectiveness of the subsequent balance adjustment, and promotes the stability and safety of the application process of the grinding wheel machine body 1. In addition, by detecting the independence of the axial and radial displacements of the balance of the grinding wheel 11, while reducing the difficulty of the detection processing unit to judge the balance difference, it can also effectively reduce the difficulty of the subsequent balance adjustment of the grinding wheel 11, and improve the efficiency and accuracy of the balance adjustment.

[0043] Figure 4 - Fig.11 The radial offset sensing component 5 is shown to include a T-shaped slider 51 which is slidably engaged in the annular waist groove 41, the upper end of the T-shaped slider 51 is fixedly connected to a hinge seat 52, the upper end of the hinge seat 52 is rotatably connected to a double-headed rotating sleeve rod 53, the upper end of the double-headed rotating sleeve rod 53 is rotatably connected to a threaded plug rod 54, the double-headed rotating sleeve rod 53 and the T-shaped slider 51 are driven by the threaded plug rod 54 to rotate along with the grinding wheel 11, and under the position restriction of the linkage ring 4 and the annular waist groove 41, the radial offset data of the grinding wheel 11 can be effectively transmitted and collected.

[0044] Figure 6 - Fig.11 It is shown that the outer end of the T-shaped slider 51 is provided with a rounded corner, and the T-shaped slider 51 and the annular waist groove 41 are clearance-matched, which can effectively reduce the friction between the T-shaped slider 51 and the annular waist groove 41, reduce the detection error caused by friction resistance, improve the sensitivity of radial deviation detection, and improve the reliability of balance detection data.

[0045] Figure 4 - Fig.11It is shown that both the left and right ends of the grinding wheel 11 are provided with detection waist grooves 12, a T-shaped column sleeve 6 is slidably clamped in the detection waist groove 12, a threaded plug rod 54 is threadedly connected in the T-shaped column sleeve 6, and the upper and lower ends of the detection waist groove 12 are fixedly connected with a balanced pressure sensing sleeve 61, and the balanced pressure sensing sleeve 61 is fixedly connected to the outer end of the T-shaped column sleeve 6, and the input end of the radial pressure acquisition unit is connected to the radial double pressure probe signal arranged in the balanced pressure sensing sleeve 61. Through the cooperation of the T-shaped column sleeve 6 and the balanced pressure sensing sleeve 61, while realizing the accompanying action of the double-head rotating sleeve rod 53, It is also possible to convert the radial offset data generated during the double-headed rotating sleeve rod 53 into bidirectional pressure data, so that the balance detection processing unit can judge the radial balance state of the grinding wheel 11 according to the bidirectional pressure data, and effectively realize high-precision detection of the balance of the grinding wheel 11 and subsequent adjustment. It should be noted here that the grinding wheel 11 with the detection waist groove 12 and the T-shaped column sleeve 6 is a special grinding wheel used for the grinding machine body 1 in conjunction with the balance detector 2, and needs to be purchased in conjunction with the balance detector 2 during procurement, so as to promote the economic benefits of the grinding machine body 1.

[0046] Figure 1 - Fig.11 It is shown that during the application process of the grinding machine body 1, the staff will input the operation instruction to the grinding machine body 1 through the control end of the grinding machine body 1. The staff can select the operation instruction according to the condition of the grinding wheel, which can be a separate balance detection instruction or a related operation instruction. After the execution instruction acquisition unit receives the separate balance detection instruction, the data is transmitted to the balance detection processing unit. The balance detection processing unit sends the data of the front balance detection speed control to the front speed adjustment unit, so that the front speed adjustment unit controls the grinding wheel motor in the grinding machine body 1 to work at the set speed, and then transmits the power to the transmission shaft 21 through the pulley transmission structure, so that the transmission shaft 21 drives the grinding wheel 11 to rotate;

[0047] When the execution instruction acquisition unit receives the relevant operation instruction, the operation instruction and the relevant operation parameters are transmitted to the balance detection processing unit. The balance detection processing unit first judges the speed data in the operation parameters. When it is judged that the speed data is less than the data set for the front balance detection speed control, the speed adjustment control is not generated. When it is judged that the speed data is greater than the data set for the front balance detection speed control, the front balance detection speed control data is sent to the front speed adjustment unit, so that the front speed adjustment unit controls the grinding wheel motor in the grinding machine body 1 to work at the set speed, thereby avoiding the problem of reduced sensitivity of balance detection due to excessive speed, effectively achieving the purpose of effectively detecting the balance of the grinding wheel 11 during the application process, ensuring the safety of the grinding wheel 11 during operation, and then transmitting the power to the transmission shaft 21 through the pulley transmission structure, so that the transmission shaft 21 drives the grinding wheel 11 to rotate;

[0048] During the rotation of the grinding wheel 11, the end face of the grinding wheel 11 will continuously contact the end face of the linkage ring 4, generating a rotational abutment effect. Therefore, when the grinding wheel 11 has an axial balance difference, the rotation of the grinding wheel 11 will produce an axial squeezing and pulling effect on the linkage ring 4, causing the linkage rings 4 on the left and right sides to produce an axial movement of the grinding wheel 11 under the action of the flexible sleeve 32. During the process of the linkage ring 4 producing an axial movement, the flexible sleeve 32 will be squeezed or released. Therefore, the rigid squeezing column 34 in the axial sensing cavity of the flexible sleeve 32 continuously squeezes or releases the elastic pressure strip 33, so that the pressure data in the elastic pressure strip 33 produces pressure data with a certain amplitude change, and then the axial pressure probe collects the pressure data and transmits the axial pressure data to the axial pressure collection unit. The axial pressure collection unit converts the axial pressure data and transmits it to the balance detection processing unit.

[0049] During the rotation of the grinding wheel 11, the grinding wheel 11 will drive the double-headed rotating sleeve rod 53, the hinge seat 52 and the T-shaped slider 51 to produce a rotation effect accompanying the grinding wheel 11 through the connection and cooperation between the T-shaped column sleeve 6 and the threaded plug rod 54. Therefore, when the grinding wheel 11 has a radial balance difference, the rotation of the grinding wheel 11 will cause the T-shaped column sleeve 6 to produce a radial squeezing and pulling effect on the balance pressure sensing sleeve 61, so that the two balance pressure sensing sleeves 61 located in the same detection waist groove 12 produce opposite deformation effects, so that the radial dual pressure probes inside it transmit the pressure change data to the radial pressure acquisition unit, and the radial pressure acquisition unit converts the pressure data and transmits it to the balance detection processing unit;

[0050] The balance detection processing unit judges and processes the received axial pressure data and radial pressure data. When it is judged that the balance difference value generated by the grinding wheel 11 is within the standard range, the balance data is transmitted to the balance data output unit, so that the balance data output unit outputs the detection data through the signal output port of the balance detector 2, which is convenient for the staff to view and analyze the data. On the one hand, it can realize the balance detection of the grinding wheel 11, and on the other hand, it can assist the staff in the maintenance and inspection of the grinding wheel 11. According to the trend of the change of the balance data of the grinding wheel 11, the application damage of the grinding wheel 11 can be judged, and the grinding wheel 11 can be replaced and maintained in time to ensure its operation stability and safety. When it is judged that the balance difference value generated by the grinding wheel 11 exceeds the standard range, while transmitting the balance data to the balance data output unit, the abnormal instruction will also be transmitted to the balance difference warning unit. The balance difference warning unit simultaneously activates the alarm and the alarm light to send an alarm signal to the staff, so that the staff can handle and adjust the abnormal grinding wheel 11 in time;

[0051] After the balance difference of the grinding wheel 11 is within the standard range, the balance detection processing unit controls the front speed adjustment unit to turn off, so that it loses the control effect on the grinding wheel motor in the grinding machine body 1. At this time, the grinding wheel motor can continue to rotate according to the operating instructions and operating parameters input by the control end of the grinding machine body 1, driving the grinding wheel 11 to operate.

[0052] During the process of the grinding wheel 11 being controlled by the grinding machine body 1 to continuously operate, the grinding wheel 11 will continuously act on the linkage ring 4, and drive the double-headed rotating sleeve rod 53, the hinge seat 52 and the T-shaped slider 51 to rotate in the annular waist groove 41 through the cooperation of the T-shaped column sleeve 6 and the threaded plug rod 54, and then make the balance pressure sensing sleeve 61 produce telescopic deformation, so the balance detection processing unit will continuously receive the pressure data transmitted by the axial pressure collection unit and the radial pressure collection unit, the balance detection processing unit will continuously judge the pressure data during the operation, and then transmit the judgment data to the balance data output unit, and then output the balance data through the signal output port of the balance detector 2, which can assist the staff The application status of the grinding wheel 11 under the operating parameters is judged, and the staff is promoted to improve the operating parameters of the grinding machine body 1. When the balance detection processing unit judges that the balance of the grinding wheel 11 during the operation is abnormal, the abnormal instruction is transmitted to the balance difference warning unit, so that the balance difference warning unit starts the alarm and the alarm light at the same time, and sends an alarm signal to the staff, so that the staff can stop the operation of the grinding machine body 1 in time to avoid damage and economic losses caused by continuous operation, thereby further realizing the continuous detection of the balance of the grinding wheel 11, which can further ensure the stability and safety of the grinding wheel 11 during the operation process and promote the economic benefits of the application of the grinding wheel 11.

[0053] Second implementation method:

[0054] Figure 1 - Figure 3A device for detecting the balance of a grinding wheel is shown, which is used as a replacement for the waist groove 12, T-shaped column sleeve 6, balance pressure sensing sleeve 61 and radial double pressure probes in the first embodiment. Both left and right ends of the grinding wheel 11 are fixedly connected with lateral seats, the upper end of the threaded plug rod 54 is rotatably connected to the lateral seat, and the double-headed rotating sleeve rod 53 includes a sleeve head rod rotatably connected to the hinge seat 52 and the threaded plug rod 54 respectively. An elastic separation sleeve is fixedly connected between the two sleeve head rods, and the input end of the radial pressure acquisition unit is connected to the signal of the radial single pressure probe arranged in the elastic separation sleeve. The setting of the elastic separation sleeve can also control the double-headed rotating sleeve rod. 53 The radial deviation data generated by the rotation of the grinding wheel 11 is collected, and then the data is transmitted to the balance detection processing unit for judgment and processing. It can be used as a replacement for the waist groove 12, T-type column sleeve 6, balance pressure sensing sleeve 61 and radial double pressure probe in the implementation mode, further expanding the application range of the grinding machine body 1, and can be suitable for the grinding wheel 11 without a transmission shaft 21, thereby promoting the selectivity of the grinding machine body 1. Conventional grinding wheels can be used. When conventional grinding wheels are used, it is necessary to independently process and connect the lateral seat and the conventional grinding wheel, which can be fixedly connected by gluing or the like.

[0055] Figure 1 - Figure 3 It is shown that when the grinding wheel 11 rotates, the cooperation between the lateral seat and the threaded plug rod 54 drives the double-headed rotating sleeve rod 53, the hinged seat 52 and the T-shaped slider 51 to rotate concomitantly, and when the grinding wheel 11 is radially offset later, the elastic separation sleeve will be stretched or contracted during the rotation of the grinding wheel 11, so that the radial single pressure probe inside it senses the pressure data and transmits the data to the radial pressure acquisition unit. The radial pressure acquisition unit converts the pressure data and transmits it to the balance detection processing unit. The balance detection processing unit judges and processes the received radial pressure data. When it is judged that the balance difference generated by the grinding wheel 11 is within the standard range, the balance data is transmitted to the balance data output unit, so that the balance data output unit can detect the balance data through the balance detection. The signal output port of the device 2 outputs the detection data, which is convenient for the staff to view and analyze the data. On the one hand, it can realize the balance detection of the grinding wheel 11, and on the other hand, it can assist the staff in the maintenance and inspection of the grinding wheel 11. According to the trend of the change of the balance data of the grinding wheel 11, the application damage of the grinding wheel 11 can be judged, and the grinding wheel 11 can be replaced and maintained in time to ensure its operation stability and safety. When it is judged that the balance difference generated by the grinding wheel 11 exceeds the standard range, while transmitting the balance data to the balance data output unit, the abnormal instruction will also be transmitted to the balance difference warning unit. The balance difference warning unit simultaneously activates the alarm and the alarm light to send an alarm signal to the staff, so that the staff can handle and adjust the abnormal grinding wheel 11 in time.

[0056] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
