Description

Technical Field

[0001] The present invention belongs to the technical field of industrial robot detection devices, and in particular relates to a reliability detection device for an industrial robot and a use method thereof. Background Art

[0002] Industrial robots refer to a type of multi-joint manipulator or multi-degree-of-freedom machine device used in the industrial field. They can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Common industrial robots are mainly composed of mechanical transmission mechanisms, sensor control systems and control systems. Due to their high production efficiency, high safety and significant economic benefits, they are widely used in various industrial fields such as electronics, logistics, and chemicals.

[0003] At present, the power units of most industrial robots are mainly composed of servo motors and reducers. As the core components of the robot, their accuracy and reliability are crucial. When conducting reliability testing on industrial robots, reliability testing devices are usually required to conduct reliability testing on the reducers of industrial robots.

[0004] The existing reliability detection device lacks a corresponding quick fixing detection mechanism and cannot quickly fix the industrial robot reducer that needs to be tested, which makes the installation and fixing process of the industrial robot reducer during use of the reliability detection device more complicated, reduces the efficiency of the industrial robot reducer detection, and at the same time, reduces the accuracy of the reliability detection device in detecting the industrial robot reducer.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a reliability detection device for an industrial robot and a method for using the same. Summary of the invention

[0006] The object of the present invention is to provide a wear-resistant seal for a valve stem, so as to solve the problem in the prior art that the industrial robot reducer cannot be quickly fixed during the use of the reliability detection device.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A reliability detection device for an industrial robot comprises: a detection base, a mobile conveying mechanism, a fast fixing detection mechanism, and a lifting control mechanism;

[0009] A pair of detection components are connected to one side of the detection base;

[0010] The mobile conveying mechanism is arranged between a pair of the detection components, and the mobile conveying mechanism comprises a mobile conveying plate, and a pair of symmetrically distributed driving screws are arranged on one side of the mobile conveying plate close to the detection base, and a plurality of supporting sliders are connected between the driving screws and the mobile conveying plate, and the supporting sliders are provided with internal threads matching the driving screws;

[0011] The quick fixing detection mechanism is arranged on the side of the mobile conveying plate away from the detection base, and the quick fixing detection mechanism includes a fixed plate, and both sides of the fixed plate are provided with limited sliding grooves, and a driving shaft is arranged in the limited sliding groove, and a moving slider is threadedly connected to the outer side of the driving shaft, and an L-shaped clamping plate is fixedly connected to the side of the moving slider away from the fixed plate;

[0012] The lifting control mechanism is arranged between the movable conveying plate and the fixed plate, and the lifting control mechanism comprises a fixed support, in which a lifting control seat is arranged, and the lifting control seat is fixedly connected to the fixed plate.

[0013] Furthermore, a pair of driving screw rods are connected to fixed seats on both sides, and the fixed seats are fixedly connected to the detection machine base, so that the driving screw rods can be supported and fixed by the fixed seats. One end of the driving screw rod located outside the fixed seat is connected to a driving pulley, and the driving pulley drives the driving screw rod to rotate.

[0014] Furthermore, a synchronous transmission belt is connected to the outer side of the driving pulley, and the synchronous transmission belt serves to connect the driving pulley and the transmission pulley, so that the driving pulley rotates accordingly with the rotation of the transmission pulley under the action of the synchronous transmission belt. The side of the synchronous transmission belt away from the driving pulley is connected to the transmission pulley, and the transmission pulley serves to transmit power to the mobile conveying motor.

[0015] Furthermore, a protective shell is provided on the outer side of the transmission pulley, which facilitates the isolation and protection of the synchronous transmission belt through the protective shell, thereby improving the operation safety of the synchronous transmission belt. The end of the transmission pulley located outside the protective shell is connected to a mobile conveying motor, and the mobile conveying motor serves to provide power, so that the rotation state of the driving screw can be controlled by controlling the operation of the mobile conveying motor.

[0016] Furthermore, external threads in opposite directions are bored on both sides of the driving shaft. By boring the external threads in opposite directions, a pair of movable sliders can move in opposite directions under the interaction of the internal and external threads. A fixed motor is connected to one end of the driving shaft outside the fixed plate. The fixed motor provides power, so that the rotational driving state of the driving shaft can be controlled by controlling the operating state of the fixed motor.

[0017] Furthermore, an auxiliary support plate is provided on the side where a pair of L-shaped clamping plates are close to each other, so that the auxiliary support plate can play a role of auxiliary fixed support. A sealing limit cylinder is provided on the side of the auxiliary support plate close to the L-shaped clamping plate. The sealing limit cylinder is located in the L-shaped clamping plate, so that the sealing limit cylinder can play a role of supporting and limiting the sealing compression rod.

[0018] Furthermore, a sealing compression rod is connected between the auxiliary support plate and the sealing limit cylinder, which serves to connect the auxiliary support plate and the sealing limit cylinder, thereby facilitating compression control of the buffer spring through movement of the auxiliary support plate. A buffer spring is connected to the side of the sealing compression rod away from the auxiliary support plate, thereby facilitating buffer support for the auxiliary support plate through contraction and resetting of the buffer spring.

[0019] Furthermore, one side of the buffer spring is connected to an air vent, which serves to connect the sealing limit cylinder and the buffer air cushion, so that the gas in the sealing limit cylinder is transported to the buffer air cushion through the air vent under the compression of the sealing compression rod. The end of the air vent away from the sealing limit cylinder is connected to the buffer air cushion, so that the stability of the connection and fixation of the L-shaped clamping plate is improved through the expansion of the buffer air cushion.

[0020] Furthermore, a pair of lifting control rods are connected to the internal thread of the lifting control seat, and the pair of lifting control rods support and limit the lifting control seat, and at the same time facilitate the lifting and moving of the lifting control seat under the interaction of internal and external threads. The ends of the pair of lifting control rods away from the lifting control seat are fixedly connected to driving gears, and the driving gears drive and control the lifting control seat. A transmission gear is meshed between the pair of driving gears, and the transmission gears transmit the power of the lifting motor. The transmission gear is connected to the lifting motor, and the lifting motor provides power, so that the lifting state of the lifting control seat can be controlled by controlling the running state of the lifting motor.

[0021] A method for using a reliability detection device for an industrial robot comprises the following steps:

[0022] S1, by controlling the operation of the mobile conveying motor to drive the driving pulley to rotate, the driving pulley rotates accordingly with the rotation of the driving pulley under the action of the synchronous transmission belt, and the driving screw is rotationally driven by the synchronous transmission belt;

[0023] S2. When a pair of driving screws rotate under the action of the driving pulley, the supporting slider can drive the movable conveying plate to move under the action of the internal and external threads, and the fixed plate is moved to the specified position through the movement of the movable conveying plate;

[0024] S3. When the fixed plate moves to the specified position, the user can place the industrial robot reducer to be tested on the fixed plate, and drive the drive shaft to rotate by controlling the operation of the fixed motor. Since the two sides of the drive shaft are drilled with external threads in opposite directions, a pair of moving sliders can drive the L-shaped clamping plate to center and fix the industrial robot reducer under the interaction of the internal and external threads;

[0025] S4. During the movement of the L-shaped clamping plate, the buffer spring is compressed through the interaction between the industrial robot and the auxiliary support plate. During the movement of the buffer spring, the gas in the sealing limit cylinder is transported to the buffer air cushion through the air pipe. The expansion of the buffer air cushion buffers the connection between the L-shaped clamping plate and the industrial robot reducer, thereby improving the stability of the subsequent connection of the industrial robot reducer.

[0026] S5. Subsequently, the fixed plate can be moved between a pair of detection components under the action of the movable conveying plate along with the operation of the movable conveying motor;

[0027] S6. When the fixed plate moves between a pair of detection components, the operation of the lifting motor can be controlled to drive a pair of driving gears to rotate, so that the lifting control seat can be lifted and lowered under the interaction of the internal and external threads. The height of the fixed plate can be adjusted by lifting the lifting control seat, thereby improving the convenience of connecting the industrial robot reducer and the detection component on the fixed plate.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] The present invention can quickly fix the industrial robot reducer that needs to be tested by arranging a corresponding quick fixing detection mechanism for the reliability detection device, thereby simplifying the process of installing and fixing the industrial robot reducer during use of the reliability detection device, significantly improving the efficiency of detecting the industrial robot reducer, and greatly improving the accuracy of the reliability detection device in detecting the industrial robot reducer.
