Description

Technical Field

[0001] This utility model relates to the field of instrument testing technology, specifically to an industrial automatic control testing device. Background Technology

[0002] Industrial automatic control instruments are monitors for industrial equipment, capable of real-time detection of data during equipment operation. To ensure that the quality of industrial automatic control instruments meets standards and can stably perform real-time detection of industrial equipment, detection and processing of industrial automatic control instruments are required.

[0003] In Chinese utility model patents, such as CN221811594U, a testing device for industrial automatic control instruments is disclosed. By using bolts connected to multiple sets of threaded holes, adjusting the placement position of the slide plate can drive the motor and the first grooved wheel to move synchronously, so that the first grooved wheel can be placed corresponding to the third grooved wheel of different diameter at the reducer. Then, the two are connected by a belt, and the motor can drive the reducer to drive the cam to rotate at different speeds. The cam can cooperate with the compression spring to make the placement platform vibrate at different frequencies, which can detect industrial automatic control instruments at different vibration frequencies. The operation is relatively convenient.

[0004] However, the aforementioned control instrument testing equipment can only detect horizontal vibrations. But the vibrations of the instruments under specific operating conditions are often multi-dimensional and complex, not just in a single horizontal direction. The above technology cannot simulate such a complex multi-directional vibration environment, resulting in a large deviation between the test results and the actual operating conditions. Therefore, it is necessary to redesign an industrial automatic control testing equipment to address the above problems. Utility Model Content

[0005] One technical problem to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an industrial automatic control testing device that solves the problem that existing industrial automatic control instrument testing devices can only detect horizontal vibrations and cannot simulate multi-directional composite vibrations, resulting in large deviations between the test results and actual working conditions.

[0007] Two technical solutions

[0008] To achieve the above objectives, this utility model provides the following technical solution: an industrial automatic control and testing device, comprising a base, a plurality of spring telescopic rods symmetrically mounted on the top surface of the base, a top plate being mounted on the top ends of the plurality of spring telescopic rods, a rectangular seat being fixedly mounted on the top surface of the top plate, a worktable being slidably connected within the rectangular seat, a clamping assembly being mounted on the top surface of the worktable, a horizontal vibration assembly being mounted on the top surface of the top plate, and the horizontal vibration assembly driving the worktable to vibrate horizontally, a vibration motor being mounted on both outer sides of the top plate, and a limiting mechanism being mounted on the top surface of the base, and the limiting mechanism restricting the vibration of the top plate.

[0009] Preferably, the horizontal vibration assembly includes two support rods, which are symmetrically installed on the top surface of the top plate. The two support rods are rotatably connected to a crankshaft. Multiple connecting rods are rotatably connected to the outer side of the crankshaft. A side plate is fixedly installed on the outer side of the worktable, and the other end of each connecting rod is rotatably connected to the corresponding side plate.

[0010] Preferably, the clamping assembly includes a square groove, which is diagonally formed on the top surface of the workbench. Two threaded sleeves are symmetrically slidably connected in the square groove. A double-ended screw is rotatably connected in the square groove, and the two threaded sleeves are symmetrically threaded to the outside of the double-ended screw. A right-angle plate is fixedly installed on the top surface of each threaded sleeve, and the two right-angle plates are arranged in a mirror image.

[0011] Preferably, the limiting mechanism includes multiple hydraulic cylinders, which are symmetrically installed on the top surface of the base, and a support plate is fixedly installed on the top of each hydraulic cylinder.

[0012] Preferably, a second motor is fixedly installed on the outer side of one of the support rods, and the output shaft of the second motor is coaxially connected to the crankshaft; a first motor is fixedly installed on the outer side of the worktable, and the output shaft of the first motor is coaxially connected to the double-ended screw.

[0013] Preferably, both the second motor and the first motor are conical rotor motors, and guide rails are fixedly installed on both sides of the rectangular base, with each guide rail being slidably connected to the worktable.

[0014] Three beneficial effects

[0015] Compared with the prior art, this utility model provides an industrial automatic control and detection device, which has the following beneficial effects:

[0016] 1. This utility model uses devices such as a horizontal vibration component, a vibration motor, and a spring telescopic rod to simulate the combined horizontal and vertical vibration of industrial automatic control instruments. The horizontal vibration component drives the instrument to move horizontally back and forth, and the vibration motor, in conjunction with the spring telescopic rod, causes the top plate to vibrate up and down. This can simulate complex working conditions, making the detection more realistic and comprehensively evaluating the stability of the instrument under multi-directional vibration.

[0017] 2. This utility model realizes the driving of horizontal vibration and the switching of vibration modes through devices such as support rods, crankshafts, side plates, connecting rods, second motors, hydraulic cylinders, and support plates. The second motor drives the crankshaft to rotate, which drives the worktable to vibrate horizontally through the connecting rods and side plates. The hydraulic cylinder pushes the support plate to lift the top plate, which can cancel vertical vibration and flexibly select single or compound vibration modes to meet different testing needs.

[0018] 3. This utility model achieves stable clamping of instruments of different specifications through a first motor, a double-headed screw, a threaded sleeve, a square groove, and a right-angle plate. The first motor drives the double-headed screw to rotate, causing the threaded sleeve in the square groove to move diagonally relative to the right-angle plate, preventing the threaded sleeve from rotating, ensuring a firm clamping, adapting to a variety of instruments, and improving the versatility of the testing equipment.

Detailed Implementation

[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0024] This utility model provides a technical solution for an industrial automatic control and detection equipment:

[0025] Please see Figures 1-3 An industrial automatic control and testing device includes a base 1, a plurality of spring telescopic rods 2 symmetrically mounted on the top surface of the base 1, a top plate 3 being mounted on the top of the plurality of spring telescopic rods 2, a rectangular seat 4 fixedly mounted on the top surface of the top plate 3, a worktable 5 slidably connected inside the rectangular seat 4, a clamping assembly being mounted on the top surface of the worktable 5, a horizontal vibration assembly being mounted on the top surface of the top plate 3, and the horizontal vibration assembly driving the worktable 5 to vibrate horizontally, a vibration motor 6 being mounted on both outer sides of the top plate 3, and a limit mechanism being mounted on the top surface of the base 1, and the limit mechanism limiting the vibration of the top plate 3;

[0026] With the cooperation of the vibration motor 6 and the spring telescopic rod 2, the top plate 3 can be adjusted to generate up and down vibration, and the horizontal vibration component can drive the worktable 5 to vibrate horizontally, which can meet the vibration simulation of complex working conditions and make the vibration detection simulation of the instrument held by the clamping component more accurate.

[0027] Furthermore, the horizontal vibration assembly includes two support rods 9, which are symmetrically installed on the top surface of the top plate 3. The two support rods 9 are rotatably connected to a crankshaft 10. Multiple connecting rods 11 are rotatably connected to the outer side of the crankshaft 10. A side plate 12 is fixedly installed on the outer side of the worktable 5, and the other end of each connecting rod 11 is rotatably connected to the corresponding side plate 12.

[0028] The rotation of the crankshaft 10 can pull the connecting rod 11 to drive the worktable 5 to slide back and forth, thereby achieving a horizontal vibration effect.

[0029] Furthermore, the clamping assembly includes a square groove 14, which is diagonally opened on the top surface of the worktable 5. Two threaded sleeves 17 are symmetrically slidably connected inside the square groove 14. A double-ended screw 16 is rotatably connected inside the square groove 14. The two threaded sleeves 17 are symmetrically threaded to the outside of the double-ended screw 16. A right-angle plate 18 is fixedly installed on the top surface of each threaded sleeve 17, and the two right-angle plates 18 are arranged in a mirror image.

[0030] By moving the two right-angle plates 18 diagonally relative to each other, instruments of different specifications can be clamped, and the engagement of the threaded sleeve 17 with the square groove 14 can prevent the threaded sleeve 17 from rotating, so that it can only slide linearly.

[0031] Furthermore, the limiting mechanism includes multiple hydraulic cylinders 7, which are symmetrically installed on the top surface of the base 1. Each hydraulic cylinder 7 has a support plate 8 fixedly installed at its top. The hydraulic cylinder 7 drives the support plate 8 to lift upward, stretching the spring telescopic rod 2, thereby removing vertical vibration. The operator can select the combination of horizontal and vertical vibration to realize the simulation of complex working conditions, and can also perform specific simulations only for horizontal or vertical vibration.

[0032] Furthermore, a second motor 19 is fixedly installed on the outer side of one of the support rods 9, and the output shaft of the second motor 19 is coaxially connected to the crankshaft 10. A first motor 15 is fixedly installed on the outer side of the worktable 5, and the output shaft of the first motor 15 is coaxially connected to the double-ended screw 16.

[0033] Furthermore, both the second motor 19 and the first motor 15 are conical rotor motors, and their output shafts can be locked after power failure, thereby ensuring the stability of their output shaft connection components. Guide rails 13 are fixedly installed on both sides of the rectangular base 4, and each guide rail 13 is slidably connected to the worktable 5.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] First, place the instrument to be tested at the center of the top surface of the workbench 5, start the first motor 15, and the first motor 15 drives the double-headed screw 16 to rotate in the square groove 14. Since the two threaded sleeves 17 are symmetrically threaded on the outside of the double-headed screw 16, and the threaded sleeves 17 are slidingly engaged with the square groove 14 and cannot rotate, the two threaded sleeves 17 will move diagonally relative to each other along the square groove 14. Subsequently, the two mirror-set right-angled plates 18 approach each other synchronously until they tightly clamp the two sides of the instrument, thus completing the fixation of the instrument.

[0036] Next, set the vibration parameters according to the detection requirements. If horizontal vibration needs to be simulated, start the second motor 19. Its output shaft drives the crankshaft 10 to rotate between the two support rods 9. The crankshaft 10 pulls the side plate 12 through the outer connecting rod 11, so that the worktable 5 slides back and forth horizontally along the guide rail 13 in the rectangular seat 4 to realize the simulation of horizontal vibration.

[0037] If it is necessary to superimpose vertical vibration, start the vibration motor 6, and at the same time control the hydraulic cylinder 7 to retract, the support plate 8 will detach from the top plate 3, and the spring telescopic rod 2 will extend and retract under the action of the vibration motor 6, driving the top plate 3 to vibrate vertically. By adjusting the frequency of the vibration motor 6 and the second motor 19, complex working conditions can be simulated.

[0038] If you need to test a specific direction, simply adjust the hydraulic cylinder 7 to lift the top plate 3 or turn off the corresponding motor.

[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
