Description

Technical Field

[0001] This utility model relates to the field of balance detection technology, and more specifically, to a roller balance detection device. Background Technology

[0002] In mechanical transmission, rollers typically refer to cylindrical rotating components (such as rolling mill rolls and conveyor rolls). Gear couplings are mainly used to connect two rotating shafts to achieve smooth transmission of torque and rotational motion. The core functions involve the coordinated operation of three major factors: roller body structural parameters (such as diameter, wall thickness, and material properties), tooth number selection (the matching relationship between module and tooth number), and displacement system (optimizing meshing performance by adjusting the radial position of the gear tooth profile). The roller body structure determines the load-bearing capacity and dynamic response characteristics of the coupling. The tooth number design directly affects the transmission ratio accuracy and tooth surface contact strength, while the displacement system balances strength and lifespan requirements by adjusting the tooth surface load distribution. That is, by establishing a dynamic correlation between roller body geometric parameters, tooth number optimization logic, and displacement coefficient, the coupling achieves adaptive matching of performance under multiple working conditions. During the roller balancing test, due to the stability of the fixed position and the obstruction during fixing, the balancing test of the test roller may be inaccurate, requiring re-testing using a balancing test device.

[0003] While existing balance testing devices can perform balance testing on rollers to understand their balance status, unnecessary friction or interference can easily occur between the fixing structure and the roller body during the balance testing process. This makes it difficult for the roller body to be tested in a natural, stress-free state, thus affecting the accuracy of the balance test results. In addition, the fixing method may consume more time and manpower, is not convenient to operate, and may even cause certain damage to the roller body due to improper fixing, thereby increasing maintenance costs and shortening the service life of the roller.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a roller balance detection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A roller balance detection device includes: a base; a moving component disposed on the top of the base; a rotating component disposed in the middle of the base; a stabilizing mechanism symmetrically disposed on the top of the base; a detection seat disposed on one side of the base; a photoelectric speed sensor disposed on one side of the detection seat; and a control panel disposed on the other side of the detection seat.

[0008] Furthermore, in order to enable the components of the stabilizing mechanism to move horizontally to accommodate rollers of different sizes and positions, the moving assembly includes a mounting groove on the top of the base, a dual-axis motor mounted in the center of the mounting groove, and threaded rods on both output ends of the dual-axis motor; and several abutting brushes are provided on the inner wall of the top of the mounting groove.

[0009] Furthermore, to ensure accurate detection of the rotating roller, the rotating assembly includes a placement plate located in the middle of the base, a servo motor on the top of the placement plate, a rotating shaft connected to one side of the servo motor, a pulley connected to the rotating shaft, a belt connected to the pulley, and a rotating roller connected to one end of the belt.

[0010] Furthermore, to prevent the rotating roller from shaking or shifting during the inspection process due to unstable fixing, thereby improving the accuracy and stability of the rotating roller inspection, the stabilizing mechanism includes a mounting frame symmetrically arranged on the top of the base. A movable block is located in the middle of the mounting frame, and end blocks are symmetrically arranged on both sides of the movable block. Each end block has a limit groove inside. A hydraulic cylinder is located inside the mounting frame, with a hydraulic rod connected to its output end. A push rod is connected to the top of the hydraulic rod, and connecting rods are located at both ends of the push rod. A concave block is located at the top of the connecting rod, and a roller is located inside the concave block. A connecting block is connected to one side of the roller, and a stabilizing plate is connected to one side of the connecting block. A pressure sensor is located inside the stabilizing plate. Several rollers are located at both ends of the stabilizing plate. A movable rod that mates with the middle of the connecting rod is located inside the mounting frame. The movable block mates with a threaded rod. Slide rails that mate with the limit grooves are symmetrically arranged on the top of the base. The push rod has an inverted U-shaped structure, and the stabilizing plate has an arc-shaped structure. The two ends of the push rod are connected to one end of the movable rod via a movable shaft, and the concave block is connected to the roller via a movable shaft.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model incorporates a moving component, a rotating component, and a stabilizing mechanism. Firstly, the moving component allows for flexible position adjustment, quickly adapting to rollers of different sizes and saving positioning time. This avoids excessive preparation time due to repeated position adjustments, thus improving testing efficiency. After positioning, the stabilizing mechanism, with its arc-shaped structure, conforms to the roller shape, reducing damage and providing stable fixation. This prevents the roller from wobbling or shifting during testing due to unstable fixation, ensuring balanced testing, improving accuracy and operational stability, reducing maintenance costs, and extending roller lifespan. The rotating component smoothly transmits power via belt drive, reducing interference and ensuring accurate roller testing.

[0013] 2. By setting up a moving component, the present invention, through the coordinated cooperation of a dual-axis motor, a threaded rod, and a brush, can play a certain role in buffering and guiding during the movement of the stabilizing mechanism, making the movement more stable, thereby enabling the stabilizing mechanism and other components to move in the horizontal direction to adapt to rollers of different sizes and positions.

[0014] 3. By setting up a rotating component, this utility model achieves rotation through the coordinated operation of a servo motor, rotating shaft, pulley, belt, and rotating roller. Driven by the pulley and belt, the rotating roller can reduce the impact and vibration during the transmission process, ensuring stable rotation of the rotating roller and thus improving the product quality in the production process.

[0015] 4. This utility model, by setting up a stabilizing mechanism, with the cooperation of components such as mounting frame, end block, limiting groove, hydraulic cylinder, hydraulic rod, push rod, connecting rod, concave block, roller, stabilizing plate and roller, can reduce friction when the stabilizing plate contacts the roller and moves or adjusts its position. This allows the stabilizing plate to move while also performing stable balance detection, avoiding shaking or deviation of the rotating roller during the detection process due to unstable fixing, thereby improving the accuracy of the rotating roller detection and the stability of its operation.

[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a roller balance detection device is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, a roller balance detection device according to an embodiment of the present utility model includes: a base 1; a moving component 2 disposed on the top of the base 1; a rotating component 3 disposed in the middle of the base 1; a stabilizing mechanism 4 symmetrically disposed on the top of the base 1; a detection seat 5 disposed on one side of the base 1; a photoelectric speed sensor 6 disposed on one side of the detection seat 5; and a control panel 7 disposed on the other side of the detection seat 5.

[0027] By employing the above-mentioned technical solution of this utility model, a moving component 2, a rotating component 3, and a stabilizing mechanism 4 are provided. First, the moving component 2 allows for flexible position adjustment, enabling quick adaptation to rollers of different sizes during placement and saving positioning time. This avoids excessive preparation time for testing due to repeated position adjustments, thereby improving testing efficiency. After positioning, the stabilizing mechanism 4 conforms to the roller shape through an arc-shaped structure, reducing damage to the roller and providing stable fixation for the rotating roller 8. This prevents the rotating roller 8 from shaking or shifting during testing due to unstable fixation, which would affect the balance of the rotating roller 8 during testing, thus improving the accuracy of testing and the stability of operation. It also reduces maintenance costs and extends the service life of the rotating roller 8. The rotating component 3 smoothly transmits power through belt drive, reducing interference and ensuring accurate testing of the rotating roller 8.

[0028] Furthermore, in practical applications, a control panel 7 is installed on one side of the detection base 5. This control panel 7 is electrically connected to the moving component 2, the rotating component 3, the stabilizing mechanism 4, and the photoelectric speed sensor 6. Operators can input relevant data through the human-machine interface of the control panel 7, thereby enabling the moving component 2, the rotating component 3, the stabilizing mechanism 4, and the photoelectric speed sensor 6 to adjust the spacing of the rotating roller 8 according to different rotating rollers 8, stabilize the fixed rotating roller 8, and detect the rotational balance of the driving rotating roller 8.

[0029] In one embodiment, the moving component 2 includes a mounting groove 201 disposed on the top of the base 1, a dual-axis motor 202 mounted in the middle of the mounting groove 201, and threaded rods 203 disposed on both output ends of the dual-axis motor 202; a plurality of abutting brushes 204 are disposed on the inner wall of the top of the mounting groove 201, thereby enabling the components of the stabilizing mechanism 4 to move in the horizontal direction to adapt to the rollers 8 of different sizes and positions.

[0030] Working principle of moving component 2: When the rotating roller 8 to be inspected is subjected to the inspection process, the dual-axis motor 202 in the middle of the mounting groove 201 is started by the control panel 7. The dual-axis motor 202 starts to run, and the two output ends drive the connected threaded rod 203 to rotate. During the rotation of the threaded rod 203, it engages with the moving block 402 of the stabilizing mechanism 4, causing the moving block 402 to move along the axial direction of the threaded rod 203. When the moving block 402 moves in the mounting groove 201, the brush 204 can move the moving block 402. It serves as a buffer and guide, reducing swaying and deviation during the movement of the stabilizing mechanism 4, ensuring that the moving parts can move smoothly and accurately to the target position, and enabling the stabilizing mechanism 4 to get closer to the rotating roller 8 for stabilizing the rotating roller 8. When it is necessary to adapt to rotating rollers 8 of different diameters, the threaded rod 203 is driven to rotate by the dual-axis motor 202, which drives the moving parts to move, thereby adjusting the relative position between the stabilizing mechanism 4 and the rotating roller 8, so that the stabilizing mechanism 4 can quickly and accurately reach the stabilizing position of the rotating roller 8, preparing for the subsequent stabilization and inspection of the rotating roller 8.

[0031] Conversely, when resetting, the dual-axis motor 202 is started via the control panel 7. The dual-axis motor 202 starts running, and the two output ends drive the connected threaded rod 203 to rotate in opposite directions, resetting the stabilizing mechanism 4 to its initial position. The dual-axis motor 202 is then stopped via the control panel 7.

[0032] In one embodiment, the rotating assembly 3 includes a placement plate 301 disposed in the middle of the base 1. A servo motor 302 is mounted on the top of the placement plate 301. A rotating shaft 303 is connected to one side of the servo motor 302. A pulley 304 is connected to the rotating shaft 303. A belt 305 is connected to the pulley 304. One end of the belt 305 is connected to a rotating roller 8, thereby ensuring accurate detection by the rotating roller 8. Furthermore, it should be noted that the placement plate 301 and the servo motor 302 are fixed together with bolts to ensure the stability of the servo motor 302's drive. This is prior art and will not be elaborated further.

[0033] Working principle of rotating component 3: The servo motor 302 on the top of the placement plate 301 is started by controlling the control panel 7. The servo motor 302 starts to run, driving the connected rotating shaft 303 to rotate. During the rotation of the rotating shaft 303, the power is transmitted to the connected pulley 304, so that the pulley 304 also rotates synchronously. The belt 305 sleeved on the pulley 304 starts to move under the action of friction as the pulley 304 rotates. One end of the belt 305 is connected to the rotating roller 8, so the belt 305 will transmit power smoothly and continuously to the rotating roller 8, driving the rotating roller 8 to rotate at a predetermined speed and direction. Conversely, when rotation balance detection is not required, the servo motor 302 is stopped by controlling the control panel 7, and the servo motor 302 stops running.

[0034] In one embodiment, the stabilizing mechanism 4 includes a mounting frame 401 symmetrically arranged on the top of the base 1. A movable block 402 is provided in the middle of the mounting frame 401, and end blocks 403 are symmetrically arranged on both sides of the movable block 402. A limit groove 404 is provided inside the end blocks 403. A hydraulic cylinder 405 is provided inside the mounting frame 401. A hydraulic rod 406 is connected to the output end of the hydraulic cylinder 405. A push rod 407 is connected to the top of the hydraulic rod 406. A connecting rod 408 is provided at both ends of the push rod 407. A concave block 409 is provided at the top of the connecting rod 408. A roller 410 is provided inside the concave block 409. A connecting block 411 is connected to one side of the roller 410. A stabilizing plate 412 is connected to one side of the connecting block 411. A pressure sensor 413 is provided inside the stabilizing plate 412. Several rollers 414 are provided at both ends of the stabilizing plate 412. A movable rod 415 that cooperates with the middle of the connecting rod 408 is provided inside the mounting frame 401. The movable block 402 cooperates with the threaded rod 203. The top of the base 1 is symmetrically equipped with slide rails 416 that cooperate with the limiting groove 404. The push rod 407 has an inverted U-shaped structure, and the stabilizing plate 412 has an arc-shaped structure. Both ends of the push rod 407 are connected to one end of the movable rod 415 via a movable shaft, and the concave block 409 is connected to the roller 410 via a movable shaft. This prevents the roller from shaking or shifting during the detection process due to unstable fixing, thereby improving the accuracy of the detection and the stability of operation. Furthermore, to ensure that the roller 8 can rotate and detect stably, several ball bearings are installed on the arc-shaped side of the stabilizing plate 412 near the roller 8. This is existing technology and will not be elaborated further.

[0035] Working principle of stabilizing mechanism 4: After the moving component 2 moves to the set position, during the stabilizing operation of the rotating roller 8, the hydraulic cylinder 405 inside the mounting frame 401 is first activated by the control panel 7. The output end of the hydraulic cylinder 405 drives the hydraulic rod 406 to extend and retract, and the push rod 407 connected to the top of the hydraulic rod 406 moves accordingly. Since the push rod 407 has an inverted U-shaped structure and both ends are connected to one end of the movable rod 415 through a movable shaft, when the push rod 407 moves, it will drive the connecting rod 408 to rotate around the connection point. Rotation causes the connecting rod 408 to move, which in turn drives the top connecting rod 408 to move. A roller 410 is connected inside the concave block 409 at the top of the connecting rod 408 via a movable shaft. A connecting block 411 on one side of the roller 410 is connected to a stabilizing plate 412. As the connecting rod 408 moves, the stabilizing plate 412 moves closer to the rotating roller 8. Simultaneously, the moving block 402 cooperates with the threaded rod 203. When the threaded rod 203 rotates, the moving block 402 can move within the mounting frame 401, providing movement for the stabilizing plate 412. The system provides precise positioning. Simultaneously, the symmetrical end blocks 403 on both sides of the moving block 402, and the internal limiting grooves 404, cooperate with the symmetrically arranged slide rails 416 on the top of the base 1, making the movement of the moving block 402 and the entire stabilizing mechanism 4 smoother and preventing deviation. When the stabilizing plate 412 gradually approaches the rotating roller 8, the stabilizing plate 412 has an arc-shaped structure, effectively stabilizing the rotating roller 8. The pressure sensor 413 inside the stabilizing plate 412 monitors the pressure applied to the rotating roller 8 in real time and feeds the data back to the control panel 7. The control panel 7 adjusts the working state of the hydraulic cylinder 405 according to preset values ​​to ensure the pressure is within a suitable range, preventing unstable fixing due to insufficient pressure or damage to the rotating roller 8 due to excessive pressure. Furthermore, the connection between the several rollers 414 at both ends of the stabilizing plate 412 and the movable shaft between the concave block 409 and the roller 410 reduces friction between the stabilizing plate 412 and the rotating roller 8 during contact and subsequent rotation detection, ensuring the rotating roller 8 can rotate smoothly and perform detection.

[0036] Conversely, when the contact is fixed, the hydraulic cylinder 405 inside the mounting frame 401 is controlled to retract via the control panel 7, which drives the hydraulic rod 406 to move downward, so that the stabilizing plate 412 gradually moves away from the rotating roller 8, and the rotating roller 8 is removed.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In practical applications, based on the size of the roller 8 to be tested, the dual-axis motor 202 in the middle of the mounting groove 201 of the moving component 2 is started by the control panel 7. The two output ends of the dual-axis motor 202 drive the threaded rod 203 to rotate, which makes threaded engagement with the moving block 402 of the stabilizing mechanism 4, so that the moving block 402 moves axially along the threaded rod 203. The brush 204 on the inner wall of the top of the mounting groove 201 plays a buffering and guiding role for the moving block 402, reducing the movement and deviation of the stabilizing mechanism 4, and allowing the stabilizing mechanism 4 to accurately approach the roller 8 (the working principle of the moving component 2 is as described above).

[0039] Move to the position of the rotating roller 8 to securely fix the rotating roller 8. The control panel 7 controls the hydraulic cylinder 405 inside the mounting frame 401 of the stabilizing mechanism 4 to start. The hydraulic rod 406 extends and retracts, driving the push rod 407 to move. The push rod 407 has an inverted U-shaped structure and its two ends are connected to the movable rod 415 through a movable shaft. This drives the connecting rod 408, the concave block 409, the roller 410, and the connecting block 411 to move, causing the stabilizing plate 412 to move closer to the rotating roller 8. The moving block 402 and the threaded rod 2 The 03 and the limiting groove 404 of the end block 403 cooperate with the slide rail 416 on the top of the base 1 to ensure smooth movement. The arc-shaped structure of the stabilizing plate 412 can better stabilize the rotating roller 8. The pressure sensor 413 inside the stabilizing plate 412 monitors the pressure and feeds it back to the control panel 7, and adjusts the hydraulic cylinder 405. The rollers 414 and concave blocks 409 at both ends of the stabilizing plate 412 are connected to the movable shaft of the roller 410 to reduce the friction with the rotating roller 8 (the working principle of the stabilizing mechanism 4 is as described above).

[0040] After stabilization, the rotating component 3 begins to work. The control panel 7 controls the servo motor 302 on the top of the placement plate 301 to start, driving the rotating shaft 303 and pulley 304 to rotate. The belt 305 on the pulley 304 drives the rotating roller 8 to rotate at a predetermined speed and direction. Finally, the rotation speed of the rotating roller 8 is balanced by the photoelectric speed sensor 6, which is electrically connected to the control panel 7. The data detected by the photoelectric speed sensor 6 will be fed back to the data panel on the control panel 7 for the operator to view, thus completing the detection of the rotating roller 8 (the working principle of the rotating component 3 is as described above).

[0041] During reset, the hydraulic cylinder 405 inside the mounting frame 401 is retracted via the control panel 7, causing the hydraulic rod 406 to move downwards, gradually moving the stabilizing plate 412 away from the rotating roller 8. Then, the servo motor 302 is stopped via the control panel 7, and the belt 305 is removed by the operator. Finally, the rotating roller 8 is supported by a robotic arm or external support frame, and the dual-axis motor 202 is started via the control panel 7. The two output ends drive the connected threaded rod 203 to rotate in opposite directions, resetting the stabilizing mechanism 4 to its initial position. The dual-axis motor 202 is stopped again via the control panel 7, and the rotating roller 8 is removed.
