Description

Technical Field

[0001] This invention belongs to the field of actuator performance testing technology, and specifically relates to an actuator performance testing device. Background Technology

[0002] Actuator performance testing equipment is crucial for evaluating the dynamic response, load capacity, accuracy, and reliability of hydraulic actuators under various operating conditions. However, traditional testing equipment typically employs a rigid, fixed structure, with the spatial layout of its mounting brackets, base, and testing components often based on a pre-designed fixed pattern. For example, the actuator's fixed position is often secured by mechanical limits or welding, making it difficult to flexibly adjust according to the actuator's actual size or testing requirements. This design means that when testing actuators of different specifications (such as length, diameter, and different mounting interface types), existing equipment often cannot accommodate non-standard sized actuators due to the non-adjustability of clamping positions or load application directions. This necessitates custom-made adapters or frequent component replacements, significantly increasing testing costs and time. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0004] An actuator performance testing device includes a base, a stand and a mounting platform mounted on the base, and a testing component mounted on the stand. During testing, one end of the actuator is mounted on the mounting platform, and the other end is mounted on the testing component. The stand is mounted on the base via a slide rail, and a base plate is hinged to the stand. The testing component is mounted on the base plate. The mounting platform is hinged to the base.

[0005] Furthermore, both the mounting platform and the testing assembly are equipped with clamping seats, and the clamping seats are equipped with several clamping fingers that move radially along the clamping seats.

[0006] Furthermore, the clamping finger has two sets of symmetrically distributed clamping plates on the side facing the center of the clamping seat. The clamping plates are assembled and connected to the clamping seat through a torsion spring shaft; the clamping plates are provided with padding.

[0007] Furthermore, a pressure sensor is mounted on the clamp of the detection component.

[0008] Furthermore, a wiring module is provided on the mounting platform.

[0009] Furthermore, the detection assembly includes a pressure cylinder, a mounting plate, and a displacement sensing assembly; the pressure cylinder is mounted on the base plate, the mounting plate is connected to the output end of the pressure cylinder, and a clamping seat is located on the mounting plate; the displacement sensing assembly includes a displacement rail and a detection slider that is slidably mounted with the displacement rail, the displacement rail is located on the base plate, and the detection slider is located on the mounting plate.

[0010] Furthermore, there are at least two sets of pressure cylinders.

[0011] Furthermore, the base has wing plates on both sides, and slide rails are provided on both the upper and lower sides of the wing plates. The bottom of the stand has a base, and the base has a slider that matches the slide rails.

[0012] Furthermore, the base is provided with a first fixing hole, and the base platform is provided with a second fixing hole arranged linearly along the slide rail; when the upright is adjusted to the correct position, the first fixing hole and the corresponding second fixing hole are connected by a fixing pin to fix the upright.

[0013] Compared with the prior art, this application has the following beneficial technical effects:

[0014] 1. The stand is assembled to the base via slide rails and the base plate is rotated and adjusted via hinges. The mounting platform is also hinged to the base, allowing for flexible adjustment of the positions of the testing components and the mounting platform. This design improves the spatial adaptability of the device, meeting the testing requirements of actuators of different sizes, while also facilitating quick positioning of the clamping positions at both ends of the actuator by operators, thus improving testing efficiency.

[0015] 2. The radially movable gripping fingers on the clamping base can adjust the clamping range, avoiding the size limitations of traditional fixed fixtures, enhancing the versatility of the device, reducing the cumbersome operation of changing fixtures, and lowering testing costs. Furthermore, the gripping fingers can achieve self-adaptive clamping using the elastic deformation of torsion springs, ensuring that the gripping fingers always apply a uniform clamping force to the actuator, preventing clamping failure or damage due to excessive tightness or looseness. The padding on the clamping plate protects the actuator surface from scratches while increasing friction and improving clamping stability.

[0016] 3. The wiring module provides a standardized interface for the electrical connection of the actuator, and the wiring is short, which makes the base platform simple and reduces the safety risks caused by problems such as tangled or excessively long wires.

[0017] 4. The upper and lower double slide rail design on both sides of the base enhances the guiding accuracy and stability during the movement of the upright, preventing damage to the slide rail and slider on one side due to pressure. The fixing pin, combined with the first fixing hole on the base and the second fixing hole on the base, can lock the position of the upright, ensuring the stability of the device during testing.

During testing, one end of the actuator is mounted on the mounting platform 300, and the other end is mounted on the testing component 400. The support frame 200 is mounted on the base 100 via a slide rail 110, and a base plate 210 is hinged to the support frame 200. The testing component 400 is mounted on the base plate 210. The mounting platform 300 is hinged to the base 100. This application utilizes the adjustable design of the support frame 200 and the mounting platform 300, allowing for flexible adjustment of the positions of the testing component 400 and the mounting platform 300. This design improves the spatial adaptability of the device, meeting the testing requirements of actuators of different sizes, and also facilitates quick positioning of the clamping positions at both ends of the actuator by the operator, thus improving testing efficiency.

[0033] Example 1

[0034] In one embodiment of this application, both the mounting platform 300 and the detection assembly 400 are equipped with clamping seats 500, and the clamping seats 500 are equipped with a plurality of clamping fingers 510 that move radially along the clamping seats 500. Two sets of symmetrically distributed clamping plates 511 are provided on the side of the clamping fingers 510 facing the center of the clamping seats 500. The clamping plates 511 are connected to the clamping seats 500 via torsion spring shafts 512; a pad 513 is provided on the clamping plates 511. The clamping fingers 510 can adjust the clamping range, avoiding the size limitations of traditional fixing fixtures, enhancing the versatility of the device, reducing the cumbersome operation of changing fixtures, and lowering testing costs. Furthermore, the clamping fingers 510 can achieve adaptive clamping using the elastic deformation of the torsion springs, ensuring that the clamping fingers 510 always apply a uniform clamping force to the actuator, preventing clamping failure or damage due to excessive tightness or looseness. The pad 513 on the clamping plates 511 protects the actuator surface from scratches while increasing friction and improving clamping stability.

[0035] Example 2

[0036] As one embodiment of this application, the mounting platform 300 is provided with a wiring module 310. The wiring module 310 provides a standardized interface for the electrical connection of the actuator, and the wiring is short, making the platform 100 simple and reducing the safety risks caused by problems such as tangled or excessively long wires.

[0037] Example 3

[0038] As one embodiment of this application, the detection component 400 includes a pressure cylinder 410, a mounting plate 420, and a displacement sensing component. There are at least two sets of pressure cylinders 410. The design of two sets of pressure cylinders 410 replaces the guide rod, allowing the detection component 400 to have a higher rated working pressure while maintaining a simpler structural layout. The pressure cylinders 410 are mounted on the base plate 210, and the mounting plate 420 is connected to the output end of the pressure cylinders 410. A clamping seat 500 is located on the mounting plate 420 and is equipped with a pressure sensor. The displacement sensing component includes a displacement rail 430 and a detection slider 431 slidably mounted to the displacement rail 430. The displacement rail 430 is located on the base plate 210, and the detection slider 431 is located on the mounting plate 420. The pressure sensor and displacement sensor work together to comprehensively evaluate the mechanical and kinematic performance of the actuator under different operating conditions, providing richer data support for actuator performance optimization and fault diagnosis.

[0039] The base 100 has wing plates 120 on both sides, and slide rails 110 on both the upper and lower sides of the wing plates 120. The bottom of the stand 200 has a base 220, and the base 220 has a slider 221 that matches the slide rails 110. The base 220 has a first fixing hole 222, and the base 100 has second fixing holes 101 arranged linearly along the slide rails 110. When the stand 200 is adjusted to the correct position, the first fixing hole 222 and the corresponding second fixing hole 101 are connected by a fixing pin 230 to fix the stand 200. The upper and lower double slide rails 110 design enhances the guiding accuracy and stability of the stand 200 during movement and avoids damage to the slide rails 110 and sliders 221 on one side due to pressure. The fixing pin 230, combined with the first fixing hole 222 on the base 220 and the second fixing hole 101 on the base 100, can lock the position of the stand 200 and ensure the stability of the device during testing.
