Description

TECHNICAL FIELD

[0001] The utility model relates to a grinding wheel piece detection device technical field, concretely is a grinding wheel piece static balance detection device. BACKGROUND

[0002] If there is unbalance in the production process of the grinding wheel piece, vibration will be generated during grinding, resulting in the decrease of the size precision and surface finish of the workpiece. Static balance detection can timely discover and correct the unbalance problem, so that the grinding wheel piece remains stable during grinding, thereby improving the size precision and surface finish of the workpiece and meeting the requirements of high-precision machining. If there is unbalance problem under high-speed rotation of the grinding wheel piece, a large centrifugal force will be generated, which may cause the grinding wheel to break and fly out, endangering the personal safety of the operator. Static balance detection can timely discover and correct the unbalance of the grinding wheel, reduce the risk and protect the safety of the operator.

[0003] In the disclosed Chinese patent application with publication number CN208953200U, the patent name is a quality balance detection device for grinding wheel piece. The prior art adopts the rotary emission and reception of light rays by the reflection type sensor. The light rays emitted by the reflection type sensor can form an annular plane after one rotation without obstruction. As long as the highest point of the measured grinding wheel piece is lower than the annular plane, the reception of light rays will not be blocked, and the inaccurate measurement results caused by different inclined directions of the measured grinding wheel piece can be avoided. Therefore, the prior art can realize balance detection of the grinding wheel piece. Although the prior art can realize balance detection of the grinding wheel piece, the prior art still has certain limitations in specific implementation.

[0004] In the specific implementation process of the prior art, the reflection type sensor in the prior art lacks a shielding mechanism. The reflection type sensor is always exposed. In the industrial production environment, there are various light sources on site, such as natural light and lighting lamps. These external light rays may mistakenly enter the receiving part of the reflection type sensor, causing the receiving part to misjudge whether the light rays are blocked, thereby affecting the accuracy of the detection results.

[0025] Please refer to Figures 1 to 5 The utility model provides technical scheme: a kind of grinding wheel piece static balance detection device, including opposite emission sensor 5, opposite emission sensor 5 includes transmitter (also namely the emission part of opposite emission sensor 5), receiver (also namely the receiving part of opposite emission sensor 5).Opposite emission sensor 5 is used to carry out balance detection to the grinding wheel piece 9 located in box 1.

[0026] A kind of grinding wheel piece static balance detection device includes box 1, jacking component, driving component, detection port is set on the bottom wall of box 1, two box doors 2 are arranged on the inner bottom wall of box 1 and located at detection port.

[0027] Wherein, the upper middle part of box 1 is fixedly connected with connecting column 4, connecting column 4 is fixedly installed on existing rotating equipment, and rotating equipment is used to drive box 1 to rotate by connecting column 4.Jacking component is used to drive grinding wheel piece 9 to move up and down, so that grinding wheel piece 9 can slowly extend into the inside of box 1.Driving component is used to drive box door 2 to open or close.

[0028] The inner top wall of the box body 1 is fixedly provided with a connecting column 13, and the lower end of the connecting column 13 is fixedly connected with a mounting plate 12. Two shaft rods are transversely arranged at the two ends of the mounting plate 12, and the shaft rods are rotationally connected with the mounting plate 12. A transmitter is fixedly arranged on the outer sidewall of one of the shaft rods at one end of the mounting plate 12, and a receiver is fixedly arranged on the outer sidewall of one of the shaft rods at the other end of the mounting plate 12. The receiver and the transmitter are respectively hung at the two ends of the mounting plate 12.

[0029] The driving component comprises two servo motors 10, which are fixedly arranged at the two ends of the mounting plate 12. The output shaft end of the servo motor 10 is coaxially fixedly connected with one end of the shaft rod. The servo motor 10 is drivingly connected with the box door 2 through the shaft rod, and the servo motor 10 drives the box door 2 to open or close. The servo motor 10 is used to drive the box door 2 to open or close.

[0030] The jacking component comprises a grinding wheel piece 9 and a jack pin 3, and the jack pin 3 drives the grinding wheel piece 9 to move up and down in the box body 1. The jacking component further comprises a top sleeve 14 and a servo electric cylinder. The jack pin 3 is fixedly arranged at the output shaft end of the servo electric cylinder, and a recessed groove is formed at the center of the lower surface of the top sleeve 14. The top sleeve 14 is arranged on the upper end of the jack pin 3, and the upper end of the jack pin 3 is arranged in the recessed groove of the top sleeve 14. The grinding wheel piece 9 is sleeved on the top sleeve 14. The servo electric cylinder is fixedly arranged on the detection table. When the servo electric cylinder is started, the output shaft of the servo electric cylinder moves up and down, and drives the jack pin 3 to move up or down. When the jack pin 3 moves up, the top sleeve 14 is pushed to move up, and the top sleeve 14 drives the grinding wheel piece 9 to move up. The centers of the grinding wheel piece 9, the top sleeve 14 and the jack pin 3 are on the same axis.

[0031] When the servo motor 10 is started, the servo motor 10 drives the box door 2 to open. After the box door 2 is opened, the jack pin 3 jacks up the grinding wheel piece 9 to move through the detection opening, so that the grinding wheel piece 9 is located in the box body 1. The output shaft of the servo motor 10 is reversely rotated and drives the shaft rod to reset, and the shaft rod drives the box door 2 to reset and close. The balance detection of the grinding wheel piece 9 is performed by using the reflection type sensor 5. A detection space is formed between the transmitter and the receiver of the reflection type sensor 5. The transmitter emits light, and the receiver receives the light. When there is no object in the detection space, the light can be smoothly transmitted from the transmitter to the receiver. Due to the mass imbalance of the grinding wheel piece 9, the grinding wheel piece 9 will tilt to one side under the action of gravity after being jacked up. The degree of tilt is positively correlated with the degree of mass imbalance of the grinding wheel piece 9.

[0032] The emitter of the opposite emitting sensor 5 emits light, and the light can form a ring plane after one rotation without obstruction. If the highest point of the measured grinding wheel piece 9 is lower than the ring plane, the light will not be blocked, and the receiver can normally receive the light. If the highest point of the measured grinding wheel piece 9 exceeds the ring plane, the light will be blocked, and the receiver cannot receive the light. This blocking signal indicates that the inclination of the grinding wheel piece 9 exceeds the allowed range, that is, the quality balance of the grinding wheel piece does not meet the requirements.

[0033] Specifically, the driving component includes two linkage assemblies located on the sides where the two ends of the mounting plate 12 are located. The output shaft of the servo motor 10 drives the shaft rod to rotate, and the shaft rod drives the box door 2 to move through the linkage assembly. The linkage assembly includes a gear 11, a sliding rail 8, a rack 6, a connecting rod 7, one end of the sliding rail 8 is fixedly connected with the inner side wall of the box body 1, the rack 6 is inserted on the sliding rail 8 and is in sliding connection with the sliding rail 8, the upper end of the connecting rod 7 is fixedly connected with the rack 6, the lower end of the connecting rod 7 is fixedly connected with the box door 2, the gear 11 is sleeved on the outer side wall of one end of the shaft rod and is in fixed connection with the shaft rod, and the gear 11 is in engagement with the rack 6.

[0034] In use, as shown in Figure 2 , the opposite emitting sensor 5 is in a horizontal state, at this time the box door 2 is in an open state, at this time the grinding wheel piece 9 is placed on the top sleeve 14, the output shaft of the servo motor pushes the top pin 3 to move upward, and the top pin 3 pushes the grinding wheel piece 9 to move upward through the top sleeve 14 and enters the box body 1 through the detection port.

[0035] Start the servo motor 10, and the rotation of the output shaft of the servo motor 10 drives the shaft rod to rotate partially, and the shaft rod drives the emitter or receiver of the opposite emitting sensor 5 to rotate by 90 degrees. After the emitter or receiver is rotated by 90 degrees, the emitter or receiver is in a vertical state with the mounting plate 12 (see Figure 3 ). During this period, the shaft rod drives the gear 11 to rotate when it rotates partially, the gear 11 drives the rack 6 engaged therewith to slide in the sliding rail 8, the rack 6 slides towards the direction where the grinding wheel piece 9 is located, the rack 6 drives the box door 2 to move through the connecting rod 7, and the box door 2 slides on the bottom wall of the box body 1 and covers the detection port, thereby shielding and closing the detection port and making the inside of the box body 1 in a closed state without other interfering light.

[0036] In order to provide a light-free environment for the opposite emitting sensor 5, thereby avoiding the influence of environmental light on the balance detection of the grinding wheel piece 9 by the opposite emitting sensor 5, and further improving the accuracy and effect of the detection of the device, the opposite emitting sensor 5 is always in the box body 1, and the opposite emitting sensor 5 is protected from external forces and damage.

[0037] The balance detection of the grinding wheel piece 9 is performed after the box doors 2 seal the detection port, a through hole is arranged in the middle of the abutted two box doors 2, the diameter of the through hole is larger than the diameter of the ejector pin 3, the ejector pin 3 can slide up and down in the through hole, and the box doors 2 will not interfere with the ejector pin 3. The ejector pin 3 pushes the grinding wheel piece 9 to rise to the set position, and the external rotating device and the against-the-light sensor 5 are started. The external rotating device drives the box body 1 to rotate through the connecting column 4, the against-the-light sensor 5 rotates with the box body 1 and performs the balance detection on the grinding wheel piece 9.

[0038] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
