Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a tooling for testing the life of an actuator cylinder. Background Technology

[0002] As an actuator in a hydraulic or pneumatic system, the reliability and service life of the actuator directly affect the stable operation of the entire system. Therefore, before the actuator is put into use, it is usually necessary to conduct a rigorous life test to simulate its actual working conditions and verify its durability. During the life test, the actuator needs to be securely mounted on the test bench, which requires the use of special tooling fixtures.

[0003] The tooling fixtures used in actuator life tests are usually designed in a simple way. They often use rigid clamping blocks for specific actuator models. The clamping structure of such fixtures has fixed dimensions and can only be matched with actuators of a specific shape or diameter, resulting in poor versatility.

[0004] When it is necessary to test actuators of different specifications or shapes, operators must change the entire set of tooling fixtures, or spend a lot of time manually loosening bolts, adjusting the position of clamping blocks and re-locking them. This clamping method, which relies on manual adjustment, is not only cumbersome in operation, but also time-consuming and labor-intensive, resulting in excessively long test preparation time. Especially in the R&D or quality inspection stages where the test parts need to be changed frequently, this inefficient clamping method seriously affects the overall test progress.

[0005] Existing actuator testing fixtures have significant shortcomings in terms of clamping versatility and ease of operation, failing to meet the requirements of modern testing for high efficiency and adaptability. There is an urgent need for a fixture that can automatically and quickly adapt to and clamp different actuators to solve the above problems.

[0006] Therefore, this utility model proposes a tooling for testing the life of an actuator cylinder to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of poor clamping versatility and the need to change clamps when clamping actuators of different specifications in the existing fixtures for actuator life testing, which leads to cumbersome operation and low testing efficiency, this utility model aims to provide a fixture for actuator life testing with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a tooling for testing the life of an actuator cylinder, comprising: a base, and a fixed seat detachably mounted on the top of the base; the tooling also includes a clamping mechanism disposed on the fixed seat.

[0009] The clamping mechanism includes a mounting groove on the top of the fixed base, a bidirectional lead screw rotatably connected to the mounting groove, and two sliders slidably connected to the inner wall of the mounting groove and threadedly connected to the bidirectional lead screw. The two clamping blocks are respectively fixed to the top of the two sliders.

[0010] Furthermore, the clamping mechanism also includes a transmission assembly for driving the bidirectional lead screw to rotate; the transmission assembly includes a servo motor fixed to the front side of the bottom of the fixed base, a gear one connected to the output shaft of the servo motor, and a gear two rotatably connected to the fixed base and meshing with the gear one, the gear two being coaxially fixedly connected to the bidirectional lead screw.

[0011] Preferably, in order to improve the adaptability to workpieces with different shapes and the clamping stability, a crescent groove is provided on each of the two clamping blocks on an adjacent side, and an elastic rubber block is fixedly connected in each crescent groove, so as to adapt to the workpiece surface by utilizing the flexible deformation of the elastic rubber block.

[0012] Preferably, in order to protect the transmission components inside the mounting slot from contamination by external dust or test debris, the clamping mechanism further includes an elastic dustproof strip, which is fixedly connected to the top of the two adjacent sides of the sliders and covers the opening of the mounting slot.

[0013] Preferably, in order to achieve precise control of the clamping process or data monitoring of the clamping state, the clamping mechanism further includes a displacement sensor, which is fixed to the top front side of the fixed base and is used to measure the moving distance of the slider.

[0014] Preferably, in order to achieve quick installation and precise positioning of the fixing seat on the base, the tooling further includes a fixing mechanism, which includes a wedge block fixed to the bottom of the fixing seat and a wedge groove opened on the top of the base, wherein the wedge block and the wedge groove are slidably engaged.

[0015] Furthermore, in order to achieve rapid locking of the fixing seat in the vertical direction, the fixing mechanism also includes an elastic buckle fixed to the bottom of the fixing seat and a slot opened on the top of the base. The elastic buckle engages with the slot when the fixing seat is pressed down.

[0016] Furthermore, in order to achieve a stable locking of the fixing seat in the horizontal direction, the fixing mechanism also includes a fixing shaft, which is slidably inserted through the base and laterally passes through the wedge block; a fixing groove is provided on the right side of the base to guide the fixing shaft to slide in.

[0017] Preferably, in order to prevent the fixed shaft from accidentally loosening or slipping during the test vibration, the fixing mechanism further includes a limiting component. The limiting component includes a limiting pin fixed to the outer wall of the fixed shaft and a limiting groove opened on the right side of the base. After the fixed shaft is installed in place, the limiting pin can be rotatably engaged in the limiting groove to achieve final locking of the fixed shaft.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a tooling for testing the life of an actuator cylinder, which aims to solve the problems of poor tooling versatility, the need to change fixtures to hold different workpieces, and the cumbersome installation and disassembly that lead to low testing efficiency in the prior art.

[0031] like Figure 1 and Figure 2 As shown, a tooling for testing the life of an actuator cylinder includes a base 1 and a fixed seat 2 detachably mounted on the top of the base 1. The base 1 serves as the mounting base for the entire device, while the fixed seat 2 supports the subsequent clamping mechanism 3.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a clamping mechanism 3 is provided on the fixed base 2. The clamping mechanism 3 includes a mounting groove 301 opened on the top of the fixed base 2, a bidirectional lead screw 302 rotatably connected to the mounting groove 301, two sliders 303 slidably connected to the inner wall of the mounting groove 301, and both sliders 303 are threadedly connected to the bidirectional lead screw 302. Two clamping blocks 304 are respectively fixed to the top of the two sliders 303.

[0033] The clamping mechanism 3 also includes a transmission assembly 309 for driving the bidirectional lead screw 302 to rotate, such as... Figure 4As shown, the transmission assembly 309 includes a servo motor 3091 fixed to the front side of the bottom of the fixed base 2. The transmission assembly 309 also includes a first gear 3092, which is connected to the output shaft of the servo motor 3091. The transmission assembly 309 also includes a second gear 3093, which is rotatably connected to the fixed base 2 and meshes with the first gear 3092. The second gear 3093 is coaxially fixedly connected to the bidirectional lead screw 302.

[0034] To achieve adaptive clamping of different actuators, the technical solution of this embodiment lies in the specific structure of the clamping block 304 and its auxiliary components.

[0035] Please refer to Figure 1 and Figure 2 Each of the two clamping blocks 304 has a crescent groove 305 on one side of its adjacent side, and an elastic rubber block 306 is fixedly connected in the crescent groove 305. When the transmission assembly 309 drives the bidirectional lead screw 302 to rotate, the two sliders 303 drive the two clamping blocks 304 to move towards each other, and finally clamp the actuator cylinder through the two elastic rubber blocks 306. This structure, which utilizes the high elasticity and flexibility of the elastic rubber block 306, can adapt to actuator cylinders with different shapes or curved surfaces, provides stable friction and prevents damage to the workpiece surface, and realizes universal clamping.

[0036] To protect the precision components inside the mounting slot 301, such as Figure 1 As shown, the clamping mechanism 3 also includes an elastic dustproof strip 307. The elastic dustproof strip 307 is fixedly connected to the top of the adjacent side of the two sliders 303 and covers the opening of the mounting groove 301. When the sliders 303 move towards each other or away from each other, the elastic dustproof strip 307 extends or compresses accordingly, always keeping the mounting groove 301 covered and preventing impurities from falling in during the test.

[0037] In addition, such as Figure 1 As shown, the clamping mechanism 3 also includes a displacement sensor 308, which is fixed to the top front side of the fixed base 2. Its measuring end is connected to the slider 303 therein, and is used to measure the moving distance or opening size of the clamping block 304 in real time, thereby realizing precise control or data feedback of the clamping process.

[0038] Based on the above embodiments, the present invention also includes a fixing mechanism 4 for realizing quick and stable installation and disassembly between the fixing seat 2 and the base 1.

[0039] As a preferred embodiment, please refer to Figure 4 In order to achieve rapid positioning, the fixing mechanism 4 includes a wedge block 401 fixed to the bottom of the fixing base 2 and a wedge groove 402 opened on the top of the base 1, with the wedge block 401 and the wedge groove 402 slidingly engaged.

[0040] As a further limitation on fixed mechanism 4, please refer to Figure 4 In order to achieve vertical locking, the fixing mechanism 4 also includes an elastic buckle 405 fixed to the bottom of the fixing base 2 and a slot 406 opened on the top of the base 1, the elastic buckle 405 and the slot 406 engaging.

[0041] As another preferred embodiment, please refer to Figure 2 and Figure 4 In order to achieve final horizontal locking, the fixing mechanism 4 also includes a fixing shaft 404, which is slidably mounted on the base 1 and passes laterally through the wedge block 401; a fixing groove 403 is provided on the right side of the base 1 to guide the fixing shaft 404 to slide in.

[0042] To prevent the fixed shaft 404 from loosening or falling off, please refer to... Figure 2 The fixing mechanism 4 also includes a limiting component 407; the limiting component 407 includes a limiting pin 4071 fixed to the outer wall of the fixing shaft 404, and a limiting groove 4072 opened on the right side of the base 1, wherein the limiting pin 4071 is rotatably inserted into the limiting groove 4072.

[0043] Working principle: When testing the lifespan of the actuator cylinder, the fixed base 2 is placed at a suitable position on top of the base 1. Then, by starting the transmission assembly 309, the servo motor 3091, fixed to the front bottom of the fixed base 2, drives the gear 1 3092 to rotate. Simultaneously, since the gear 1 3092 and the gear 2 3093 are connected, the bidirectional lead screw 302, which is rotatably connected to the mounting groove 301 on the top of the fixed base 2, rotates synchronously. Furthermore, because two sliders 303 are slidably connected to the front and rear sides of the inner wall of the mounting groove 301, and the two sliders 303 are threadedly connected to the bidirectional lead screw 302, the two sliders 303 can move towards each other when the bidirectional lead screw 302 rotates. A crescent groove 3 is provided on each adjacent side of the two clamping blocks 304 fixed to the top of the two sliders 303. 05. Elastic rubber blocks 306 are fixedly connected in both crescent grooves 305, so that when the sliders 303 move towards each other, the two elastic rubber blocks 306 can clamp the actuators of different shapes. During the test, the elastic dustproof strips 307 fixedly connected to the top of the adjacent side of the two sliders 303 can protect the placement groove 301 and prevent impurities from falling into the placement groove 301 during the test. The displacement sensor 308 fixed to the front of the top of the fixed base 2 can also measure the moving distance of the clamping block 304. The device can clamp actuators of different shapes by cooperating with the various components of the clamping mechanism 3 and using the high elasticity and flexibility of the elastic rubber blocks 306, reducing downtime, increasing the overall applicability of the device, and improving work efficiency.

[0044] Furthermore, when the fixing seat 2 is quickly installed on top of the base 1, the wedge-shaped block 401 fixed to the bottom of the fixing seat 2 is slid into the wedge-shaped groove 402 opened at a suitable position on the top of the base 1. Then, the fixing seat 2 is pressed down, so that the multiple elastic buckles 405 fixed to the bottom of the fixing seat 2 can engage with the corresponding slots 406 opened at the top of the base 1, thereby initially limiting the position of the fixing seat 2 in the vertical direction. Then, because the base 1 has a fixing groove 403 on the right side, after the fixing seat 2 is installed in place, it slides into the fixing shaft 404 from the right side of the base 1 along the fixing groove 403. The fixed shaft 404 passes through the wedge block 401, and then the limiting pin 4071 fixed to the outer wall of the fixed shaft 404 is rotated counterclockwise from the right side of the base 1, so that the limiting pin 4071 slides into the limiting groove 4072 opened on the right side of the base 1. This allows the fixed shaft 404 to restrict the position of the fixed seat 2 in the horizontal direction. By utilizing the cooperation of the two parts in the limiting assembly 407, the fixed shaft 404 is prevented from falling off or loosening. Thus, the fixing mechanism 4 restricts the fixed seat 2 in both the horizontal and vertical directions, simplifying the operation process, avoiding the use of additional tools during installation and disassembly, and improving the overall experimental efficiency.
