[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0029] like Figures 1-5 As shown, this utility model discloses an automatic compressor discharge volume detection device, including a frame 1, a base plate 2 connected to the middle of the frame 1, an electrical system for controlling electrical components at the lower end of the base plate 2, and a detection system for detecting the compressor discharge volume at the upper end of the base plate 2. The detection system includes:

[0030] The pressure head mechanism is located at the top of the frame 1. The pressure head mechanism includes a cylindrical support column 4 connected to the base plate 2. The support column 4 is connected to the pressure head cylinder 5 through a connecting frame. The output end of the pressure head cylinder 5 is connected to a pressure head component 6.

[0031] A dotting mechanism located at the top of the frame 1, the dotting mechanism including a dotting machine 7, the dotting machine 7 being connected to the support column 4 via a connecting frame 2;

[0032] The exhaust volume detection mechanism installed on the upper end surface of the seat plate 2 comprises a round bottom plate 8, which is rotationally connected to the upper end surface of the seat plate 2 and locked by locking screws, and the upper end of the round bottom plate 8 is connected with an X-axis movement assembly, the upper end of the X-axis movement assembly is connected with a Y-axis movement assembly, the upper end of the Y-axis movement assembly is connected with a Z-axis movement assembly, the Z-axis movement assembly is connected with a joint main push air cylinder 10 through a circular mounting plate 9, and the output end of the joint main push air cylinder 10 is connected with a joint assembly. Embodiment one:

[0033] In the present application, the loosening of the locking screw one allows the connecting block one 111 to slide on the support column 4, so as to adjust the up-and-down position of the pressure head cylinder 5, and the loosening of the locking screw two allows the connecting block two 211 to slide on the support column 4, so as to adjust the up-and-down position of the dotter 7, and the loosening of the locking screw three and the locking screw four allows the connecting block two 211 and the connecting block three 213 to slide on the connecting column 212, so as to adjust the front-and-back position of the dotter 7, and the further rotation of the connecting block two 211 and the connecting block three 213 can adjust the angle of the dotter 7, so that the dotter 7 can point to the dottable position of the compressor in a better position. The above-mentioned adjustment functions are mainly used to adapt to different models of compressors.

[0034] When the compressor is transported from the conveying line to the preset position (which can be identified by a position sensor), the pressure head cylinder 5 drives the pressure head piece 6 to move downward, so that the pressure head piece 6 tightly fixes the compressor at the lower end, and then the exhaust volume detection mechanism detects the exhaust volume of the compressor, if the detection is unqualified, the electrical system controls the dotter 7 to dot the surface of the unqualified compressor, and the compressor with the dotting mark is sent to the repair line in the subsequent conveying process. Embodiment two:

[0035] The X-axis movement assembly in the application comprises an X-axis sliding rail 311, a sliding plate 312 and a first screw transmission assembly. When the first locking handle 313 is loosened to release the first screw 315, the first screw 315 is rotated by adjusting the first hand wheel 314 to drive the first ball sliding block to move, and then the sliding plate 312 connected with the first ball sliding block moves along the X-axis sliding rail 311. Similarly, the Y-axis movement assembly comprises a Y-axis sliding rail 411, a sliding plate 412, a second screw transmission assembly. When the second locking handle 413 is loosened to release the second screw 415, the sliding plate 412 moves along the Y-axis sliding rail 411 by adjusting the second hand wheel 414. The Z-axis movement assembly comprises a sliding rod 511, a lifting installation sliding block 512 and a third screw transmission assembly. When the third locking handle 514 is loosened to release the sliding rod 511, the lifting installation sliding block 512 moves up and down along the sliding rod 511 by adjusting the third hand wheel 515. That is, the joint assembly can move linearly in three axial directions by the X-axis movement assembly, the Y-axis movement assembly and the Z-axis movement assembly, so as to adjust the position thereof.

[0036] In the application, the circular bottom plate 8 is rotationally connected to the upper end surface of the seat plate 2 and is locked by the fifth locking screw. When the fifth locking screw is loosened, the circular bottom plate 8 can rotate around the Z-axis by a certain angle, so that the joint assembly can rotate around the Z-axis by a certain angle. The circular mounting plate 9 is rotationally connected to the vertical plate 513 and is locked by the sixth locking screw. When the sixth locking screw is loosened, the circular mounting plate 9 can rotate around the X-axis by a certain angle by pushing the push rod, so that the joint assembly can rotate around the X-axis by a certain angle. The angle of the joint assembly is adjusted by the above-mentioned rotary movement.

[0037] As described above, when the compressor is changed in production, the position and angle of the joint assembly need to be adjusted by the above-mentioned adjustment operation to adapt to the changed compressor. The above-mentioned operation is a manual operation. The reason why automatic control is not designed is that there may be certain errors in different batches of the same type of compressor (non-high-precision product) in production, and it is difficult to accurately position by automatic control. Embodiment three

[0038] In the application, the joint assembly comprises a guide sleeve 611, a quick plug connector 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 plug connector 612 connects the air pipe (copper pipe) of the compressor. The air pipe of the compressor is inserted into the tapered interface until it extends into the sealing ring 613 for sealing. The compressor is powered on and started at low pressure, and exhausts. The airflow enters the micro-flow gas path element connected with the exhaust connector 622 through the inner cavity of the compression rod 615 and the exhaust connector 622, detects the exhaust flow pressure, and detects whether the exhaust is qualified.

[0039] Further, the joint sub-pushing air cylinder 614 is connected with the rear end of the guide sleeve 611, the output end of the joint sub-pushing air cylinder 614 is connected with the pressing rod 615, one end of the pressing rod 615 abuts on the sealing ring 613, that is, the sealing ring 613 is extruded by the pressing rod 615, so that the sealing ring 613 can wrap the air pipe of the compressor more tightly, thereby improving the sealing performance.

[0040] Further, the joint sub-pushing air cylinder 614 is connected with the rear end of the guide sleeve 611, the output end of the joint sub-pushing air cylinder 614 is connected with the pressing rod 615, one end of the pressing rod 615 abuts on the sealing ring 613, that is, the sealing ring 613 is extruded by the pressing rod 615, so that the sealing ring 613 can wrap the air pipe of the compressor more tightly, thereby improving the sealing performance.

[0041] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
