DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0020] like Figure 1-5 As shown, according to the present invention, a compressor exhaust volume automatic detection device is disclosed, comprising a frame 1, a seat plate 2 is connected to the middle of the frame 1, an electrical system for controlling electrical components is provided at the lower end of the seat plate 2, and a detection system for detecting the compressor exhaust volume is provided at the upper end of the seat plate 2, and the detection system comprises: A pressing head mechanism is located at the top of the frame 1, and the pressing head mechanism includes a cylindrical support column 4 connected to the base plate 2, and the support column 4 is connected to the pressing head cylinder 5 through a connecting frame 1, and the output end of the pressing head cylinder 5 is connected to the pressing head member 6; A dotting mechanism located on the top of the frame 1, the dotting mechanism comprising a dotting machine 7, the dotting machine 7 is connected to the support column 4 through a connecting frame 2; The exhaust volume detection mechanism is installed on the upper end surface of the seat plate 2, and the exhaust volume detection mechanism includes a circular bottom plate 8, which is rotatably connected to the upper end surface of the seat plate 2 and locked by a locking screw 5. The upper end of the circular bottom plate 8 is connected to an X-axis motion component, the upper end of the X-axis motion component is connected to a Y-axis motion component, the upper end of the Y-axis motion component is connected to a Z-axis motion component, and the Z-axis motion component is connected to a joint main push cylinder 10 through a circular mounting plate 9, and the output end of the joint main push cylinder 10 is connected to a joint component. Embodiment 1:

[0021] In the present application, the locking screw one is loosened, and the connecting block one 111 can slide on the support column 4, so as to adjust the up and down position of the pressure head cylinder 5. Similarly, the locking screw two is loosened, and the connecting block two 211 can slide on the support column 4, so as to adjust the up and down position of the dotting machine 7. At the same time, the locking screw three and the locking screw four are loosened, and the connecting block two 211 and the connecting block three 213 can slide on the connecting column 212, so as to adjust the front and back position of the dotting machine 7. Further rotating the connecting block two 211 and the connecting block three 213 can adjust the angle of the dotting machine 7, so that the dotting machine 7 can finally point to the dotting point of the compressor at a better position. The above-mentioned adjustment function is mainly used to adapt to compressors of different models.

[0022] When the compressor is transported from the conveyor line to a preset position (identifiable by a position sensor), the pressure head cylinder 5 drives the pressure head member 6 to move downward, so that the pressure head member 6 presses and fixes the compressor at its lower end, and then the exhaust volume of the compressor is detected by the exhaust volume detection mechanism. If the detection is unqualified, the electrical system controls the dotting machine 7 to mark the surface of the unqualified compressor. During the subsequent transportation process, the compressor with the dot mark is sent to the repair line. Embodiment 2:

[0023] In the present application, the X-axis motion assembly includes an X-axis slide rail 311, a slide plate 312 and a screw transmission assembly 1. When the locking handle 313 is released to release the screw rod 315, the screw rod 315 is rotated by adjusting the hand wheel 314 to drive the ball slider 1 to move, and then the slide plate 312 connected to the ball slider 1 moves along the X-axis slide rail 311; similarly, the Y-axis motion assembly includes a Y-axis slide rail 411, a slide plate 412 and a screw transmission assembly 2. When the locking handle 413 is released to release the screw rod 415, the slide plate 412 can be moved along the Y-axis slide rail 411 by adjusting the hand wheel 414; and the Z-axis motion assembly includes a slide bar 511, a lifting installation slide bar 512 and a screw transmission assembly 3. When the locking handle 3 514 is released to release the slide bar 511, the lifting installation slide bar 512 can be moved up and down along the slide bar 511 by adjusting the hand wheel 3 515. That is, the joint assembly can be linearly moved in three axial directions through the X-axis motion assembly, the Y-axis motion assembly and the Z-axis motion assembly, thereby adjusting its position.

[0024] In the present application, the circular bottom plate 8 is rotatably connected to the upper end surface of the seat plate 2 and is locked by a locking screw five. When the locking screw five is loosened, the circular bottom plate 8 can be rotated around the Z axis by a certain angle, so that the joint assembly can be rotated around the Z axis by a certain angle; and the circular mounting plate 9 is rotatably connected to the vertical plate 513 and is locked by a locking screw six. When the locking screw six is ​​loosened, the lever can be moved to rotate the circular mounting plate 9 around the X axis by a certain angle, so that the joint assembly can be rotated around the X axis by a certain angle; the angle of the joint assembly is adjusted by the above-mentioned rotational movement.

[0025] In summary, when the compressor is replaced during production, the position and angle of the joint assembly need to be adjusted through the above-mentioned adjustment operations to adapt to the replaced compressor. The above-mentioned operations are all manual operations. The reason why automatic control is not designed is that the same type of compressors (non-high-precision products) may have certain errors when produced in different batches, and automatic control is difficult to accurately position. Embodiment three:

[0026] The joint assembly in the present application includes a guide sleeve 611, a quick-connect joint 612, and a sealing ring 613, and is driven by the joint main push cylinder 10. When the exhaust volume detection mechanism detects the compressor, the joint main push cylinder 10 drives the joint assembly to move forward, so that the quick-connect joint 612 connects to the air pipe (a copper pipe) of the compressor. The air pipe of the compressor is inserted from the conical interface until it extends into the sealing ring 613 for sealing. The compressor is powered on and started at low pressure to exhaust. The air flow passes through the inner cavity of the clamping rod 615 and the exhaust joint 622 and enters the micro-flow air path element connected to the exhaust joint 622 to detect the exhaust flow pressure, thereby detecting whether the exhaust is qualified.

[0027] Furthermore, a joint auxiliary push cylinder 614 is connected to the rear end of the guide sleeve 611, and a clamping rod 615 is connected to the output end of the joint auxiliary push cylinder 614. One end of the clamping rod 615 abuts against the sealing ring 613, that is, the sealing ring 613 is squeezed by the clamping rod 615, so that the sealing ring 613 can wrap the air pipe of the compressor tighter, thereby improving its sealing performance.

[0028] Furthermore, the connection between the joint auxiliary push cylinder 614 and the guide sleeve 611 is a conical positioning portion 616, and the rear end of the joint auxiliary push cylinder 614 is connected to a guide rod 618, which is inserted into the positioning tube 624 on the front side of the rear limit plate 619. The front limit plate 620 is provided with a conical positioning hole compatible with the conical positioning portion 616, and a spring 623 is sleeved on the guide rod 618, one end of the spring 623 abuts on the steel plate seat 617, and the other end abuts on the rear limit plate 619, that is, the entire joint assembly has a certain amount of free space in the axial direction of the spring 623, which is limited by the limit plate and buffered by the spring 623. Its main function is to prevent the compressor air pipe from bending by buffering the free space when the quick-connect joint 612 is not completely aligned with the compressor air pipe.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
