Description

Technical Field

[0001] This utility model relates to the technical field of cylinder performance testing equipment, and in particular to a cylinder telescopic rod stroke testing device. Background Technology

[0002] Cylinder stroke detection is a crucial step in ensuring stable cylinder operation. Accurate stroke detection allows for timely adjustments to the cylinder's condition, preventing potential malfunctions. Traditional cylinder stroke detection devices calculate the cylinder stroke by directly measuring the extension and retraction lengths of the cylinder piston rod. However, during measurement, the measuring rod is prone to detaching from the cylinder piston rod, and the device has poor compatibility with cylinders of different specifications. An unsuitable cylinder placement slot can cause the cylinder to shift position during measurement, affecting the test results. Therefore, a cylinder extension rod stroke testing device was designed.

[0003] Chinese utility model patent CN202222598370.2 discloses a stroke detection device. The driving and pushing assembly includes a cylinder and a piston rod. A guide mechanism is provided on the cylinder, and a slide rod passes through the guide mechanism. A detection plate is provided on the piston rod, and the end of the slide rod slidably abuts against the detection plate. A displacement sensor for detecting the travel stroke of the slide rod is provided on the cylinder. By providing the guide mechanism and the slide rod, the contact position of the slide rod on the detection plate can be detected through the slidable contact. The invention presents several challenges. Compared to the fixed connection between the detection plate and the slide rod, the sliding rod end can be slidably abutted against the detection plate, thus avoiding the influence of the radial rotation of the piston rod on the displacement monitoring of the slide rod. This accurately reflects the movement stroke of the piston rod and ensures measurement accuracy. However, this invention has the following problems: Firstly, it does not have the function of fixing the cylinder piston rod, and the cylinder piston rod is prone to detaching from the measuring rod during the extension process. Secondly, it does not have the improvement to enhance the compatibility of cylinders of different specifications. An unsuitable cylinder placement slot can easily cause the cylinder to shift position during measurement, affecting the formation of test results. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, this utility model provides a cylinder telescopic rod stroke testing device, including a base plate 1. An automatic slide rail assembly 2 is located at the upper center of the base plate 1. The core working principle is that an object is automatically slid along a preset track by a motor drive. The motor provides power to drive the slider to move on the track. Through a precise control system, the speed and position of the slider can be precisely controlled. Therefore, the automatic slide rail assembly 2 drives the sliding table 21 to move left and right, thereby adjusting the position of the sliding table 21 according to the specifications of the cylinder 5. A fixed box 3 is located on the right rear end of the base plate 1. The fixed box 3 contains a power assembly to provide power support for the testing structure 4. The upper end of the fixed box 3 is equipped with... Test structure 4, the upper end of the automatic slide rail assembly 2 is fitted with a sliding platform 21, and two ventilation components 6 are provided above the sliding platform 21. The upper end of the ventilation components 6 is installed on the rail, so that the ventilation components 6 can move left and right, thereby better connecting the air inlet and air outlet on the cylinder 5, so that the cylinder 5 can obtain kinetic energy, and further extend the piston rod of the cylinder 5. The left end of the sliding platform 21 is provided with a baffle 22, which limits the placement position of the selection seat 24 and the left end of the cylinder 5. The upper end of the sliding platform 21 is provided with a limiting groove 23, which limits the front and rear position of the selection seat 24. The selection seat 24 is provided in the groove of the limiting groove 23, and the upper end of the selection seat 24 is provided with a medium groove 25.

[0024] Furthermore, such as Figure 2 As shown, the front end of the selection seat 24 is provided with a large groove 26, and the rear end of the selection seat 24 is provided with a small groove 27. The bottom of the large groove 26, the medium groove 25, and the small groove 27 are all provided with rubber pads 28. The large groove 26, the medium groove 25, and the small groove 27 are set on one selection seat 24, and the three are all different in size, so that one selection seat 24 can accommodate three specifications of cylinders 5, improving the applicability of the testing equipment and reducing the possibility of cylinder 5 moving.

[0025] Furthermore, the surface of the rubber pad 28 is provided with a groove 29, which reduces the collision between the cylinder 5 and the selection seat 24, and also increases the friction between the cylinder 5 and the selection seat 24, reducing the possibility of the cylinder 5 moving and improving the accuracy of the stroke test. The upper end of the rubber pad 28 located on the upper side is provided with the cylinder 5.

[0026] Furthermore, such as Figure 1 As shown, the test structure 4 includes a rocking arm 41, the upper end of which is movably connected to a rotating arm 42. The front end of the rotating arm 42 is provided with a fixing member 43. The lower end of the rocking arm 41 is movably connected to a fixed box 3, which can swing left and right, while the rotating arm 42 can rotate up and down. The rocking arm 41 and the rotating arm 42 together form a conventional mechanical arm to realize the position adjustment of the stroke tester 44 and ensure that the displacement of the test rod 46 and the piston rod of the cylinder 5 are on the same horizontal line.

[0027] Furthermore, the front end of the fixing member 43 is connected to the stroke tester 44. The main function of the stroke tester is to detect key parameters such as the stroke and displacement of the product to ensure that the performance and quality of the product meet the design requirements. The stroke tester 44 is provided with a display table 45 in the middle. The data tested by the test rod 46 is directly displayed on the display table 45, which is simple and clear. The left end of the stroke tester 44 is provided with a test rod 46, and the front end of the test rod 46 is provided with a fixing clip 47.

[0028] Furthermore, such as Figure 3 As shown, the left end of the fixing clamp 47 is provided with a fixing groove 471. The front and rear groove surfaces of the fixing groove 471 are symmetrically provided with circular holes 472. A screw 473 is provided in the hole 472. A clamping block 474 is provided at one end of the screw 473 located in the fixing groove 471, and a circular block 475 is provided at the end of the screw 473 away from the fixing groove 471. The circular hole 472 and the screw 473 are connected by a thread. By rotating the screw 473, the distance between the two clamping blocks 474 is adjusted, thereby ensuring that the clamping blocks 474 clamp the front end of the piston rod of the cylinder 5, ensuring that the piston rod of the cylinder 5 and the test rod 46 are on the same horizontal line, and improving the accuracy of stroke measurement.

[0029] Working process: First, based on the specifications of cylinder 5, select the appropriate size by comparing the large slot 26, medium slot 25, and small slot 27, and place the selected slot facing upwards on the selection seat 24; next, place cylinder 5 in the selected slot, with its piston rod in a fully retracted state, and control the operation button on the base plate 1 to displace the rocker arm 41 and the rotating arm 42, so that the test rod 46 of the stroke tester 44 and the piston rod of cylinder 5 are on the same horizontal line; next, rotate the screw 473 to adjust the distance between the two clamping blocks 474, thereby ensuring that the clamping blocks 474 clamp the front end of the piston rod of cylinder 5; next, connect the two air venting components 6 to the air inlet and air outlet of cylinder 5 respectively, to ventilate cylinder 5, causing the piston rod of cylinder 5 to extend, and the data measured by the test rod 46 is directly displayed on the display table 45, which is the stroke length of cylinder 5.
