However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example
[0026] Referring to Figures 1 to 4, an embodiment of the present invention is shown, which provides a spring and component testing fixture, including,
[0027] The transfer mechanism 100 includes a support leg 101, a mounting plate 102 fixedly installed on the side wall of the support leg 101, a support rod 103 welded to the side wall of the mounting plate 102, and a conveyor belt 104 adapted to be installed on the side wall of the mounting plate 102.
[0028] The testing mechanism 200 includes a support frame 201, a baffle 202 fixedly installed on the side wall of the support frame 201, a placement plate 203 fixedly installed on the inner wall of the baffle 202, a mounting frame 204 fixedly installed on the side wall of the support frame 201, a pressure testing component 205 disposed on the side wall of the mounting frame 204, and a pick-and-place component 206 disposed on the surface of the mounting frame 204.
[0029] Specifically, the pressure testing assembly 205 includes a hydraulic cylinder 205a fixedly mounted on the side wall of the mounting bracket 204, and a placement rod 205b fixedly mounted on the end of the hydraulic cylinder 205a. The pressure testing assembly 205 also includes a limiting seat 205c sleeved on the surface of the placement rod 205b, and a jacking stage 205d movably connected to the end of the placement rod 205b. The pressure testing assembly 205 also includes a cylinder 205e fixedly mounted on the side wall of the mounting bracket 204, and a guide rail 205f fixedly mounted on the side wall of the mounting bracket 204.
[0030] Furthermore, the top-mounted stage 205d is designed to be used in conjunction with the hydraulic cylinder 205a, facilitating the testing of the spring rebound capability of the spring machine assembly. The movable design of the top-mounted stage 205d makes it easy to adapt to the testing of different types of springs and assemblies, increasing the applicability of the device.
[0031] Preferably, the pick-and-place assembly 206 includes a slide rail 206a fixedly mounted on the side wall of the mounting bracket 204, and a first linear motor 206b slidably connected to the surface of the slide rail 206a. The pick-and-place assembly 206 also includes a slide rod 206c fixedly mounted on the side wall of the first linear motor 206b, and a second linear motor 206d slidably connected to the surface of the slide rod 206c. The pick-and-place assembly 206 also includes a pneumatic gripper 206e fixedly mounted on the side wall of the second linear motor 206d, and a limiting rod 206f fixedly mounted on the side wall of the mounting bracket 204.
[0032] It should be noted that the first linear motor 206b is positioned on the surface of the slide rail 206a, and the pneumatic gripper 206e is an IRWIN Vise-Grip 6LN model gripper, which facilitates the gripping and placement of springs and components.
[0033] In use, the spring and assembly are placed on the placement plate 203. The first linear motor 206b is started, which moves the slide bar 206c to a position flush with the spring and assembly. The second linear motor 206d is started, which moves the pneumatic clamp 206e to above the spring. The pneumatic clamp 206e tightens, clamping the spring and assembly, and moves the spring and assembly to the top platform 205d. The hydraulic cylinder 205a is started, which moves the placement rod 205b forward. The placement rod 205b passes through the hole in the middle of the spring or presses against the end of the spring and assembly. The cylinder 205e extends and retracts, which moves the top platform 205d back and forth, thereby compressing and releasing the spring and assembly, and testing the spring and assembly's rebound ability. After the test is completed, the second linear motor 206d, in conjunction with the starter clamp, moves the tested spring and assembly to place them on the conveyor belt 104. The conveyor belt 104 transfers the spring and assembly to the next step.
[0034] In summary, through the coordinated operation of the transfer mechanism 100 and the testing mechanism 200, efficient and automated testing of springs and components is achieved. The structural design of the conveyor belt 104 and the support foot 101 ensures stable workpiece transport. The combination of the slide rail 206a, linear motor, and pneumatic gripper 206e in the pick-and-place assembly 206 enables precise gripping and positioning, allowing springs and components to be quickly transferred between the testing station and the conveyor belt 104. The pressure testing assembly 205 uses a hydraulic cylinder 205a to drive the placement rod 205b, combined with the adjustable top stage 205d and the reciprocating motion of the cylinder 205e, which can adapt to the compression and rebound performance testing of springs of different specifications. The guide rail 205f and the limiting structure further ensure the stability of the testing process and the accuracy of the data. Through the integration of mechanical, pneumatic, and hydraulic systems, testing efficiency is improved while reducing manual intervention, making it suitable for the spring quality inspection needs in a mass production environment.
