Description

Technical Field

[0001] The present invention relates to the technical field of wave springs, and in particular to a wave spring conveyor with a testing function. Background Art

[0002] Wave springs, also known as wave springs, are elastic elements with peaks and valleys on a thin metal ring. They are typically used in applications where both load and deflection are small, requiring a low spring stiffness and applying axial preload. Wave springs are particularly well-suited for applications requiring weight reduction and those constrained by limited installation space. Typical applications include aerospace, precision machinery, hydraulic seals, and high-end motors.

[0003] During the wave spring forming and manufacturing process, various tests need to be carried out. In the existing technology, the inner diameter of the wave spring is generally tested by workers using a vernier caliper to measure the wave spring multiple times to determine the inner diameter of the spring. This is not only time-consuming and labor-intensive, but also has low production efficiency. In addition, the manual operation error during the measurement process is large, resulting in inaccurate measurement data. At the same time, the temperature of the newly produced wave spring is high, and the measuring personnel are easily burned.

[0004] To this end, we propose a wave spring transporter with testing function. Summary of the Invention

[0006] Preferably, the rotating mechanism includes a rotating motor, a driving gear, a driven gear and a rotating frame, the rotating motor is fixedly mounted on the end of the robotic arm, the driving gear is fixedly mounted on the output end of the rotating motor, the rotating frame is rotatably connected to the end of the robotic arm, the driven gear is fixedly mounted on the inner wall of the rotating frame, the driven gear is engaged with the driving gear, and the grabbing mechanism is arranged on the side of the rotating frame.

[0008] Preferably, the measuring mechanism includes a mounting groove, a fixing bracket, a displacement sensor, a connecting rod and a measuring head. The mounting groove is opened on a side of the connecting block away from the fixing cylinder. The fixing bracket is fixedly connected to the connecting block. The displacement sensor is fixedly installed inside the mounting groove. One end of the connecting rod is fixedly installed on the measuring end of the displacement sensor. The connecting rod is slidably connected to the fixing bracket. The measuring head is fixedly installed on the other end of the connecting rod. The measuring head is arranged in contact with the support plate.

[0009] Preferably, the robotic arm is driven to rotate by a motor, the maximum movable radius of the robotic arm is greater than the distance between the fixing seat and the wave spring transmission belt, and a bolt hole is provided at the bottom of the fixing seat.

[0010] Preferably, one end of the rotating frame is rotatably connected to the end of the robotic arm, and the other end of the rotating frame is rotatably connected to the end of the driving gear away from the rotating motor. The shape of the rotating frame is "concave", and the grabbing mechanism is arranged on the side of the rotating frame.

[0011] Preferably, a relative protrusion is provided on the side of the sliding hole, and a groove corresponding to the protrusion is opened on the side of the sliding rod, and the width of the sliding hole protrusion is the same as that of the sliding rod groove.

[0012] Preferably, there are four support plates in total, and the support plates are coaxially arranged with the fixing tube, and the deflection angle of adjacent support plates is ninety degrees.

The short end of the connecting rod is fixedly mounted on the measuring axis of the displacement sensor, and the length of the long end of the connecting rod is equal to the sum of the maximum measuring range of the displacement sensor and the length of the piccolo end of the connecting rod.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention provides a wave spring transporter with a testing function, which has the following beneficial effects:

[0017] 1. This wave spring conveyor with a testing function is equipped with a rotating mechanism at the end of a robotic arm. After the motor is started, the driving gear rotates along with the rotating motor, while the driven gear is fixed to the rotating frame. Therefore, as the driving gear rotates, the driven gear meshing with the driving gear rotates around the driving gear, thereby driving the rotating frame to rotate. The rotation of the rotating frame controls the orientation of the grasping mechanism and the measuring mechanism, making it convenient for the grasping mechanism and the measuring mechanism to grasp and measure the wave spring.

[0018] 2. This wave spring conveyor with a testing function drives the moving block to move by rotating the grabbing motor, thereby increasing the angle between the support rod and the diameter of the moving block, and pushing the sliding rod to slide outward along the sliding hole. As the sliding rod pushes the support plate to expand, the wave spring is fixed on the support plate and grabbed to prevent the wave spring from falling. When the wave spring needs to be lowered, the grabbing motor is reversed to shrink the support plate, and the wave spring falls automatically.

[0019] 3. This wave spring conveyor with a testing function sets a displacement sensor in the connecting block. When the grabbing mechanism grabs the spring, the measuring head is always in contact with the outer side of the support plate, so that the connecting rod moves along with the support plate. The movement of the connecting rod drives the measuring end of the displacement sensor to move, and then measures the moving distance of the support plate. The diameter of the spring is calculated by a computer connected to the displacement sensor, and the multiple displacement sensors set up can reduce the measurement error.

By arranging the rotating mechanism 3 at the end of the robotic arm 2, after starting the rotating motor 31, the driving gear 32 rotates following the rotating motor 31, and the driven gear 33 is fixedly installed with the rotating frame 34. Therefore, as the driving gear 32 rotates, the driven gear 33 meshed with the driving gear 32 rotates around the driving gear 32, thereby driving the rotating frame 34 to rotate.
