Description

Technical Field

[0001] This utility model relates to the field of fault simulation, and in particular to a fault simulation test bench for position rulers. Background Technology

[0002] As a high-precision industrial device, injection molding machines rely heavily on a positioning gauge as one of their core components. This gauge monitors and provides real-time feedback on the machine's movement, ensuring the accuracy and stability of the injection molding process. Positioning gauges are typically mounted on the moving parts of the injection molding machine, achieving high-precision displacement measurement through the principles of resistance voltage division or magnetostriction. However, despite their long design life, the failure rate of positioning gauges in actual operation is significantly higher than expected, especially after one to two years of operation.

[0003] Currently, fault detection of position gauges typically requires direct testing on the injection molding machine, but this method has significant limitations. First, the testing cycle on injection molding machines is long, time-consuming, and energy-intensive, making it difficult to quickly pinpoint the cause of the fault. Second, due to space constraints, multiple position gauges cannot be tested simultaneously, leading to inconsistent testing conditions. Furthermore, injection molding machines lack high-precision fault detection methods, making it impossible to accurately determine the specific cause of the fault, requiring repeated disassembly and reassembly of the equipment for troubleshooting. These problems indicate that existing testing methods are insufficient to meet the demands for efficient and accurate fault detection. There is an urgent need for a test bench that can simulate the operating conditions of an injection molding machine and accelerate fault detection, in order to deeply analyze the failure modes and mechanisms of position gauges. Utility Model Content

[0004] In order to shorten the test cycle of fault simulation and improve test efficiency, this utility model provides a position ruler fault simulation test bench.

[0005] This utility model provides a position ruler fault simulation test bench, which adopts the following technical solution:

[0006] A position ruler failure simulation test bench includes a position ruler and a control unit for controlling the test process and data measurement. It also includes a test bench, a test fixture mechanism mounted on the test bench for mounting the position ruler, and a drive component for controlling the position ruler to reciprocate to simulate operating conditions.

[0007] By adopting the above technical solution, the test parameters are input through the control unit, and then the test fixture mechanism is controlled to adjust to the corresponding state. The position ruler is then tested through the drive component, and experimental data is collected during the test. This enables real-time monitoring and data analysis of the position ruler's operating status. Compared with the existing technology of disassembling the position ruler running on the injection molding machine for testing, this utility model can shorten the test cycle of fault simulation and improve test efficiency.

[0008] Optionally, the position ruler includes a pull rod position ruler and a slider position ruler; the test fixture mechanism includes an angle control component for fixing the pull rod position ruler and adjusting its tilt angle so that the pull rod position ruler can be tested at different angles, and a horizontal control component for fixing the slider position ruler so that the slider position ruler can be tested by horizontal sliding.

[0009] By adopting the above technical solution and setting up angle control components and horizontal control components, comprehensive testing of different position rulers under different installation angles and motion states can meet the simulation needs of various working conditions and ensure the reliability of test data.

[0010] Optionally, the angle control assembly includes a mounting base rotatably mounted on the test bench and adapted to accommodate various lengths of the tie rod position gauge, the mounting base having a mounting surface in the circumferential direction.

[0011] By adopting the above technical solution, the angle control component is equipped with an adjustable tilt angle mounting base, which is compatible with pull rod position rulers of various lengths, allowing multiple position rulers to be tested at once, thus improving testing efficiency.

[0012] Optionally, the angle control assembly further includes an electric push rod for driving the mounting base to rotate in the vertical direction, the tail end of the electric push rod being rotatably connected to the test bench, and the push rod of the electric push rod being rotatably connected to the bottom of the mounting base.

[0013] By adopting the above technical solution, the mounting base is rotated by an electric push rod, realizing automatic angle adjustment, so that different pull rod position rulers can be tested at different installation angles, meeting the diversity of testing scenarios.

[0014] Optionally, the level control assembly includes a mounting base for fixing the slider position gauge for level testing and a support frame mounted on the test bench for supporting the mounting base to form a sliding chamber below the mounting base; the pull rod position gauge passes through the sliding chamber during testing.

[0015] By adopting the above technical solution, after the fixed seat is supported by the support frame to form a sliding chamber, both the pull rod position ruler and the slider position ruler can be tested synchronously in the sliding chamber, which improves the testing efficiency of different position rulers and reduces the overall volume of the fault simulation test bench.

[0016] Optionally, the driving assembly is disposed in the sliding chamber, and the driving assembly includes a movable plate that is horizontally slidably mounted on the test bench and a linear module that drives the movable plate to slide; the pull rod position ruler is fixedly connected to the movable plate, and the slider position ruler is slidably connected to the movable plate.

[0017] By adopting the above technical solution, since both the slider position ruler and the pull rod position ruler are connected to the same moving plate, when the moving plate slides the ruler on the linear module, the slider position ruler and the pull rod position ruler can be tested simultaneously, improving the testing efficiency of rulers at different positions.

[0018] Optionally, the movable plate has several oblong through holes, and the pull rod of the pull rod position ruler passes through the oblong through holes and is fixed by a nut.

[0019] By adopting the above technical solution, the oblong through hole opened on the moving plate can accommodate pull rod position rulers of different specifications and lengths, providing a flexible fixing and limiting solution.

[0020] Optionally, the movable plate has a plurality of limiting grooves for the sliders of the slider position ruler set in different directions to be embedded in.

[0021] By adopting the above technical solution and rationally arranging the limiting grooves, multiple slider position gauges can be installed on the fixed base at the same time, and multiple slider position gauges can be tested synchronously. This optimizes the utilization rate of the tooling's internal space and improves the testing efficiency of the position gauges.

[0022] Optionally, it also includes a test cabinet, with the test bench disposed within the cavity of the test cabinet.

[0023] By adopting the above technical solution, the integrated design of the experimental platform and the test cabinet not only provides a stable working platform but also effectively utilizes space. The test cabinet provides protection for the experimental platform, reduces external interference, and ensures the accuracy and reliability of test data under different environmental conditions.

[0024] Optionally, a support frame at the bottom of the test cabinet may also be included.

[0025] By adopting the above technical solution, a bracket is set at the bottom of the test cabinet to facilitate the fixing of the test bench and improve the stability of the equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By designing an adjustable tilt angle control component and a horizontal control component for horizontal sliding tests, the test bench can adapt to the installation and testing of various types of tie rod position gauges and slider position gauges, significantly improving the versatility and adaptability of the test bench and meeting the testing requirements of position gauges of different specifications and models;

[0028] 2. By using an electric push rod to drive the mounting base to rotate in the vertical direction, accurate testing of the pull rod position gauge at different angles is achieved. At the same time, the linear module drives the sliding plate to simulate the actual operating conditions of the position gauge. This allows the test bench to accurately simulate various operating conditions of the position gauge in actual applications, providing diversified testing capabilities and ensuring the accuracy and reliability of the test results.

[0029] 3. The horizontal control component combines the support frame and the fixed seat into a sliding chamber, providing stable support for the test. At the same time, the drive component is set in the sliding chamber, and the linear module realizes the flexible sliding of the moving plate. This not only optimizes space utilization, but also ensures that the drive component can efficiently drive the position ruler to reciprocate, thereby improving test efficiency and accuracy.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] This application discloses a position ruler fault simulation test bench.

[0038] Reference Figure 1 A position ruler fault simulation test bench includes a test bench 1, a position ruler 2, a control unit 3, a test fixture mechanism 4, and a drive assembly 5. The test bench 1 serves as the mounting platform, and the control unit 3, the test fixture mechanism 4, and the drive assembly 5 are all mounted on the test bench 1. Specifically, the test fixture mechanism 4 is used for mounting the position ruler 2, the drive assembly 5 is used to drive the position ruler 2 to perform tests, and the control unit 3 is used to control the test process and data measurement.

[0039] During testing, the position ruler 2 is installed on the test fixture mechanism 4. The control unit 3 inputs the simulated parameters during the test process, thereby driving the drive component 5 to control the position ruler 2 to reciprocate with the simulated parameters. The sensor in the control unit 3 acquires the test data in real time. After the test is completed, the test data is analyzed to detect the linearity and signal stability, and to determine the fault condition of the position ruler 2.

[0040] Reference Figure 2 In this embodiment, the position ruler 2 includes a pull rod position ruler 6 and a slider position ruler 7. The pull rod position ruler 6 consists of a position ruler shell, a telescopic pull rod, and a sensing unit. The telescopic pull rod can extend and retract on the position ruler shell, and the sensing unit measures the linear displacement of the pull rod, converting the mechanical displacement into an electrical signal to achieve accurate measurement of the displacement. The slider position ruler 7 consists of a slider and a position ruler guide rail. The slider moves on the position ruler guide rail, and the linear position change is measured.

[0041] Reference Figure 2 The testing fixture mechanism 4 includes an angle control component 8 and a horizontal control component 9. The angle control component 8 is used to test the position ruler 6 of the pull rod, and the horizontal control component 9 is used to control the position ruler 7 of the slider for testing.

[0042] Reference Figure 2 and Figure 3 The angle control component 8 includes a mounting base 10 and an electric push rod 11. The mounting base 10 has a "U"-shaped structure with multiple mounting surfaces 12. The upper and lower surfaces of the horizontally positioned mounting surfaces 12 can be used to mount the pull rod position gauge 6, and the outer surfaces of the vertically positioned mounting surfaces 12 can also be used to mount the pull rod position gauge 6. Each mounting surface 12 has a series of through mounting holes 13, and the pull rod position gauge 6 is fixed to the mounting surface 12 by screws through the mounting holes 13. Because there are multiple mounting holes 13, the mounting base can accommodate pull rod position gauges 6 of different lengths.

[0043] The mounting base 10 is rotatably mounted on the test bench 1 and is driven to rotate by an electric actuator 11. The tail end of the electric actuator 11 is rotatably connected to the test bench 1, and the push rod of the electric actuator 11 is rotatably connected to the bottom of the mounting base 10. When the push rod of the electric actuator 11 extends or retracts, the mounting base 10 can rotate in the vertical direction. In this embodiment, the rotation angle of the mounting base 10 is between 0 and 15 degrees.

[0044] Reference Figure 2 and Figure 4 The horizontal control component 9 includes a fixed base 14 and a support frame 15. The support frame 15 is fixedly installed on the test bench 1 and consists of four metal rods 16 and a metal plate 17. The metal plate 17 is connected to the top of the metal rods 16, and the four metal rods 16 are located at the four corners of the metal plate 17. The fixed base 14 is fixedly installed at the bottom of the metal plate 17 and consists of three metal plates: one horizontally positioned metal plate and two vertically positioned metal plates. The vertically positioned metal plates are connected to the top of the horizontally positioned metal plates. The fixed base 14 and the support frame 15 together form an "I"-shaped structure. Slider position gauges 7 can be installed on the outer sides of the two vertically positioned metal plates of the fixed base 14, and slider position gauges 7 can be installed on the upper and lower surfaces of the left and right ends of the horizontally positioned metal plate.

[0045] Since the fixed seat 14 is installed on the support frame 15, there is a certain height between the fixed seat 14 and the test bench 1, so that a sliding chamber 24 is formed below the fixed seat 14.

[0046] Reference Figure 2 and Figure 5 The drive component 5 includes a moving plate 18 and a linear module 19.

[0047] The linear module 19 is mounted on top of the test bench 1 and located within the sliding chamber 24. A movable plate 18 is slidably mounted on top of the linear module 19. When the linear module 19 is activated, the movable plate 18 can move horizontally back and forth on the linear module 19.

[0048] The movable plate 18 has several oblong through holes 20, which are vertically oriented. When the pull rod position ruler 6 is installed on the mounting base 10, the pull rod of the pull rod position ruler 6 passes through the oblong through hole 20, and the pull rod position ruler 6 is fixed on the movable plate 18 by installing a nut at the end of the pull rod, making it difficult for it to fall out. When the pull rod position ruler 6 rotates with the angle adjustment of the mounting base 10, the pull rod of the pull rod position ruler 6 can move up and down within the oblong through hole 20.

[0049] The movable plate 18 is also provided with several limiting grooves 21, which are used for the slider of the slider position ruler 7 to be embedded and installed, thereby connecting the slider position ruler 7 with the movable plate 18.

[0050] When the linear module 19 controls the moving plate 18 to reciprocate, the pull rod of the pull rod position ruler 6 can pass through the sliding chamber 24 and move synchronously with the moving plate 18, thereby causing the pull rod of the pull rod position ruler 6 to extend and retract to test the pull rod position ruler 6. The slider of the slider position ruler 7 can move horizontally synchronously with the moving plate 18, thereby causing the slider of the slider position ruler 7 to move on the position ruler guide rail to measure the slider position ruler 7.

[0051] Before the test, the angle of the pull rod position ruler 6 is adjusted by the electric push rod 11, so that the drive component 5 drives the pull rod position ruler 6 to conduct tests under different angle conditions.

[0052] Reference Figure 1 Furthermore, the position ruler failure simulation test bench also includes a test cabinet 22 and a bracket 23. The test bench 1 is set inside the test cabinet 22, which can protect the test bench 1 and ensure that the test process of the position ruler 2 can be carried out smoothly. The bracket 23 is installed at the bottom of the test cabinet 22 to fix the test bench 1.

[0053] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
