Description

Technical Field

[0001] The utility model belongs to the technical field of polishing operations, and particularly relates to a polishing wheel size detection device for a polishing machine. Background Art

[0002] The size of the polishing wheel continues to decrease with consumption. Therefore, during automatic polishing operations, the polishing wheel size needs to be compensated. The existing compensation method generally indirectly calculates the size of the polishing wheel, which often has a certain difference from the actual size of the polishing wheel, resulting in abnormal product quality and requiring frequent manual intervention. Utility Model Content

[0003] The utility model aims to solve the above problems in the prior art and proposes a polishing wheel size detection device for a polishing machine, which can realize accurate size measurement of a running polishing wheel.

[0004] The utility model can be realized by the following technical solutions:

[0005] A polishing wheel size detection device for a polishing machine, comprising:

[0006] Bracket;

[0007] a single-axis robot mounted on the bracket;

[0008] The detection assembly includes a mounting seat, a detection plate, a tension spring, and a sensor. The mounting seat is arranged on the uniaxial robot. The uniaxial robot is used to realize the forward and backward movement of the mounting seat so that the detection plate is close to or away from the polishing wheel. The detection plate is hinged to the mounting seat. The two ends of the tension spring are respectively connected to the detection plate and the mounting seat.

[0009] When detecting the diameter of the polishing wheel, the single-axis robot drives the detection plate to contact the polishing wheel, so that the detection plate overcomes the resistance of the tension spring and rotates around the hinge point. The system combines the sensor to obtain the rotation signal of the detection plate and the motion data of the single-axis robot to accurately calculate the size of the polishing wheel.

[0010] As a further improvement of the present invention, it further includes a driving plate, which is installed on the slider of the single-axis robot, and the driving plate is driven to move by the single-axis robot driving its slider to move.

[0011] As a further improvement of the present invention, the mounting seat is arranged at the front end of the driving plate, and the detection plate is located at the front end of the mounting seat. As the driving plate moves, the mounting seat is driven to move so that the detection plate is close to or away from the polishing wheel.

[0012] As a further improvement of the present invention, when the detection plate is not in contact with the polishing wheel, the detection plate maintains an acute angle with the longitudinal surface of the mounting seat under the tension of the tension spring.

[0013] As a further improvement of the present invention, the lower end surface of the detection plate is used to contact the polishing wheel. When the detection plate is not in contact with the polishing wheel, the lower end surface of the detection plate is closer to the polishing wheel than its upper end surface.

[0014] As a further improvement of the present invention, the sensor is arranged on the mounting seat and faces the lower end surface of the detection plate.

[0015] As a further improvement of the present invention, when the detection plate contacts the polishing wheel and rotates, the straight-line distance between the detection plate and the sensor changes. The sensor transmits the collected straight-line distance signal to the system and converts it into rotation data of the detection plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When measuring the diameter of the polishing wheel, the single-axis robot drives the detection plate to contact the polishing wheel, causing the detection plate to rotate around the hinge point, overcoming the resistance of the tension spring. The system combines the sensor to obtain the rotation signal of the detection plate and the motion data of the single-axis robot to accurately calculate the size of the polishing wheel. The entire process is fully automatic and requires no human intervention, which improves calculation efficiency and avoids errors caused by human factors. It can ensure the accuracy of the polishing wheel size after compensation, thereby ensuring good product quality.

[0018] 2. The single-axis robot precisely controls the position of the drive plate, ensuring the position consistency of the detection plate and the polishing wheel when they are in contact, thereby improving the accuracy of dimensional measurement;

[0019] 3. By setting the tension spring, the detection plate has the function of automatic reset. After each test is completed, the detection plate can automatically reset and prepare for the next test, reducing unnecessary adjustment steps and ensuring that the detection plate is in the same state before each measurement, thereby improving the consistency and repeatability of the measurement.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1-5 As shown, the utility model provides a polishing wheel size detection device for a polishing machine, comprising:

[0028] Bracket 100;

[0029] A single-axis robot 110 is mounted on the support 100;

[0030] The detection assembly includes a mounting base 120, a detection plate 130, a tension spring 140 and a sensor 150. The mounting base 120 is set on the single-axis robot 110. The single-axis robot 110 realizes the forward and backward movement of the mounting base 120 to make the detection plate 130 close to or away from the polishing wheel 200. The detection plate 130 is hinged to the mounting base 120. The two ends of the tension spring 140 are respectively connected to the detection plate 130 and the mounting base 120.

[0031] When detecting the diameter of the polishing wheel 200, the single-axis robot 110 drives the detection plate 130 to contact the polishing wheel 200, so that the detection plate 130 overcomes the resistance of the tension spring 140 and rotates around the hinge point. The system combines the sensor 150 to obtain the rotation signal of the detection plate 130 and the motion data of the single-axis robot 110, and accurately calculates the size of the polishing wheel 200. The entire process is fully automatic and does not require human intervention, which improves calculation efficiency and avoids errors caused by human factors. It can ensure that the size of the polishing wheel 200 after compensation is accurate, thereby ensuring good product quality.

[0032] Preferably, a driving plate 160 is further included, which is installed on the slider of the single-axis robot 110. The single-axis robot 110 drives the slider to move, thereby driving the driving plate 160 to move.

[0033] Among them, the mounting seat 120 is arranged at the front end of the driving plate 160, and the detection plate 130 is located at the front end of the mounting seat 120. As the driving plate 160 moves, the mounting seat 120 is driven to move so that the detection plate 130 is close to or away from the polishing wheel 200. It is worth mentioning that by precisely controlling the position of the driving plate 160 through the single-axis robot 110, the position consistency of the detection plate 130 when in contact with the polishing wheel 200 can be ensured, thereby improving the accuracy of dimensional measurement.

[0034] Preferably, when the detection plate 130 is not in contact with the polishing wheel 200, the detection plate 130 maintains an acute angle with the longitudinal surface of the mounting seat 120 under the tension of the tension spring 140. Through the setting of the tension spring 140, the detection plate 130 has an automatic reset function, which means that after each detection is completed, the detection plate 130 can automatically reset and prepare for the next detection, reducing unnecessary adjustment steps and ensuring that the detection plate 130 is in the same state before each measurement, thereby improving the consistency and repeatability of the measurement.

[0035] Preferably, the lower end surface of the detection plate 130 is used to contact the polishing wheel 200. When the detection plate 130 is not in contact with the polishing wheel 200, the lower end surface of the detection plate 130 is closer to the polishing wheel 200 than its upper end surface. The sensor 150 is set on the mounting seat 120 and faces the lower end surface of the detection plate 130.

[0036] Specifically, when the detection plate 130 contacts the polishing wheel 200 and rotates, the linear distance between the detection plate 130 and the sensor 150 changes. The sensor 150 transmits the collected linear distance signal to the system and converts it into rotation data of the detection plate 130.

[0037] Among them, the lower end surface of the detection plate 130 is the side farthest from its hinge point, and its rotation angle changes more obviously. The straight-line distance between the sensor 150 and the lower end surface of the detection plate 130 also changes more obviously, thereby improving the detection accuracy and ensuring the reliability and stability of the detection process.

[0038] The technical means disclosed in the present invention are not limited to those disclosed in the above technical means, but also include technical solutions composed of any combination of the above technical features. The above is a specific embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0042] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
