[0002] A pneumatic rotary joint is an important component for transmitting compressed air or gas between rotating and stationary equipment, commonly used in automated equipment, robots, rotary tables, etc. To ensure the performance and service life of the pneumatic rotary joint, it must be regularly detected.

[0003] The detection of a pneumatic rotary joint involves multiple aspects, including appearance inspection, sealing, rotation flexibility, air tightness, pressure resistance, temperature adaptability, service life, material and internal parts, etc. Through these detection items, the performance and reliability of the joint can be comprehensively evaluated to ensure its normal operation in actual application. Regular detection and maintenance not only prolong the service life of the joint, but also avoid equipment damage or production accidents caused by joint failure.

[0004] It also includes runout detection, which is mainly used to evaluate the stability of the joint during rotation, especially its rotation accuracy and concentricity. Runout (also known as "runout" or "radial runout") refers to the deviation between the rotation axis of the joint and the theoretical axis during rotation. If the runout is too large, it may cause the joint to vibrate, produce noise, and even affect the normal operation and service life of the equipment during operation. Therefore, runout detection is an important part of the quality detection of a pneumatic rotary joint.

[0021] It is easy to understand that according to the technical scheme of the present application, those skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or as the limitation or restriction of the technical scheme of the present application.

[0022] A pneumatic rotary joint rotation jump detection device, comprising a bottom plate 1 and a supporting unit 2, a rotating fixing unit 3 and a jump detection unit 4 arranged on the bottom plate 1, the supporting unit 2 is fixedly arranged at the middle region of the bottom plate 1, the rotating fixing unit 3 and the jump unit are fixedly arranged at the two ends of the length method of the bottom plate 1, the pneumatic rotary joint is placed on the supporting unit 2, the rotating end thereof is connected with the rotating fixing unit 3, and the jump detection unit 4 is fixedly arranged above the other end of the pneumatic rotary joint and in contact with the upper surface thereof, for monitoring the jump of the pneumatic rotary joint.

[0023] Embodiment 1

[0024] Figure 1 schematically shows the front view structure of the first embodiment of the rotating runout detection device of the pneumatic rotary joint, as Figure 1 As shown, in this embodiment, the rotating fixing unit 3 includes a motor 31 fixedly arranged on the bottom plate 1. The motor 31 drives the rotating end of the pneumatic rotary joint to rotate. The rotating shaft of the motor 31 is connected to the rotating end of the pneumatic rotary joint through a connecting piece 32. One end of the connecting piece 32 is fixed to the rotating shaft of the motor 31, and the connecting piece 32 is coaxial with the rotating shaft of the motor 31. The other end of the connecting piece 32 is fixedly connected to the rotating end. The motor 31 drives the main shaft to rotate, thereby driving the rotating end to rotate through the connecting piece 32. It is worth noting that the connecting piece 32 is fixedly connected to the rotating end through thread cooperation. In this embodiment, the motor 31 needs to be lifted by the first fixing piece so that the center of the rotating shaft of the motor 31 and the center of the rotating end of the pneumatic rotary joint are coaxial, and the linear connecting piece 32 can drive the rotating end.

[0025] Embodiment 2

[0026] In this embodiment, compared with the comparative document 1, the connecting piece 32 is a universal coupling (not shown). One end of the universal coupling is fixed to the rotating shaft of the motor 31, and the other end is threadedly connected to the rotating end of the pneumatic rotary joint. The center of the rotating shaft of the motor 31 does not need to be coaxial with the center of the rotating end of the pneumatic rotary joint. The universal coupling can compensate for the positional difference between the two, so that the motor 31 can be directly fixed to the bottom plate 1.

[0027] The runout detection unit 4 includes a runout test table 41 fixedly arranged on the bottom plate 1. The center of the runout test table 41 is in contact with the upper surface of the other end of the pneumatic rotary joint. After the rotating end of the pneumatic rotary joint is fixed to the motor 31, the runout test table 41 is placed on the supporting unit 2. The center of the runout test table 41 is in contact with the upper surface of the other end of the pneumatic rotary joint. The runout of the pneumatic rotary joint during the test is monitored by the runout test table 41.

[0028] Embodiment 3

[0029] Figure 2 schematically shows the top view structure of the third embodiment of the rotating runout detection device of the pneumatic rotary joint, as Figure 2As shown, in this embodiment, based on Embodiment 1 or Embodiment 2, the aforementioned runout test gauge 41 is fixed to the base plate 1 by a fixed bracket. The fixed bracket consists of a first support rod 42 and a second support rod 43. The first support rod 42 is vertically fixed to the base plate 1, and the second support rod 43 is vertically fixed to the upper surface of the first support rod 42. The runout test gauge 41 is fixedly disposed at the end of the second support rod 43 close to the pneumatic rotary joint. That is, in this embodiment, the runout test gauge 41 is in a fixed position, which can complete the rotational runout detection process of a pneumatic rotary joint of a fixed specification.

[0030] Example 4

[0031] Figure 3 The schematic diagram shows a top view of the fourth embodiment of the pneumatic rotary joint rotation runout detection device, such as... Figure 3 As shown, in this embodiment, unlike embodiment 3, a fixing groove is provided along the length of the second support rod 43, and bolts are used to fix the second support rod 43 to the first support rod 42 through the fixing groove. By using the fixing groove and bolts, the position of the runout test gauge 41 fixed to the second support rod 43 can be adjusted and fixed, making it possible to test pneumatic rotary joints of different specifications with the support unit 2 on the rotary runout detection device. This avoids the need to set up separate detection devices for multiple specifications of pneumatic rotary joints, effectively reducing testing costs.

[0032] It is worth noting that the support unit 2 in embodiments 1-4 is fixedly installed below the end of the pneumatic rotary joint away from the rotating fixed unit 3. The support unit 2 consists of a support rod and a bracket fixedly installed on the top of the support rod. By setting the support unit 2 below the end of the pneumatic rotary joint away from the rotating fixed unit 3, since the rotating end of the pneumatic rotary joint is connected and fixed to the shaft of the motor 31, the fixed point can be used as the support point. Thus, setting the support unit 2 directly at the other end can also ensure the support function for the pneumatic rotary joint, avoiding the need to use the support unit 2 to support the entire pneumatic rotary joint on the base plate 1, effectively saving costs.

[0033] By connecting and fixing the rotating end of the pneumatic rotary joint to the rotating fixing unit 3, and fixing the runout detection unit 4 at the other end, the pneumatic rotary joint is supported and fixed by the rotating fixing unit 3 and the support unit 2. At the same time, the runout detection unit 4 completes the runout detection process of the pneumatic rotary joint. It can perform two rotation and runout detection processes at the same time, effectively reducing the detection time and improving the detection efficiency of the pneumatic rotary joint.

[0034] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should all belong to the protection scope of the present application.
