[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides a pump core testing device for a push-button pump, such as... Figure 1 and Figure 2 As shown, the device includes a workbench 1 and a testing unit 2. The testing unit 2 includes a connecting rod 201 rotatably connected to the middle of the top of the workbench 1. A turntable 202 is fixedly installed at the top of the connecting rod 201. Several sets of connecting cylinders 203 are annularly installed at the top of the turntable 202, and the top of each connecting cylinder 203 is inserted with a pump core body 204 to be tested. A rotating component 205 is provided at the bottom of the workbench 1 to drive the connecting rod 201 to rotate and adjust the position of the pump core body 204 to be tested. A testing component 206 is provided at the top of the workbench 1 to perform airtightness testing on the pump core body 204 to be tested located at the testing position.
[0023] During operation, workers insert several sets of pump core bodies 204 to be tested into the tops of several sets of connecting cylinders 203, and start the rotating component 205. The rotating component 205 drives the connecting rod 201 to rotate, and the connecting rod 201 in turn drives the turntable 202 to rotate synchronously. During the rotation of the turntable 202, one set of pump core bodies 204 to be tested moves to the testing station. At this time, the worker starts the testing component 206, which automatically presses down to form a sealed connection with the pump core body 204 to be tested and quickly carries out the airtightness test. After the airtightness test of the current pump core body 204 is completed, the rotating component 205 is started again to drive the turntable 202 to rotate, so that the next set of pump core bodies 204 to be tested can smoothly enter the testing station. This realizes the rapid and orderly switching of the pump core bodies 204 to be tested between testing stations, solving the problem that after completing one pump core airtightness test, multiple cumbersome operations are required to test the next one, which increases the cycle, reduces efficiency, and makes it difficult to meet the needs of large-scale and high-efficiency testing.
[0024] Preferably, the rotating assembly 205 includes an end face gear 2051, which is rotatably connected to the bottom end of the worktable 1. The top end of the end face gear 2051 is fixedly connected to the bottom end of the connecting rod 201. A first motor 2052 is fixedly installed at the bottom end of the worktable 1, and a cylindrical gear 2053 is fixedly connected to the output end of the first motor 2052. The cylindrical gear 2053 meshes with the end face gear 2051. When the first motor 2052 starts, it drives the cylindrical gear 2053 to rotate. The cylindrical gear 2053 meshes with the end face gear 2051 on one side, thereby driving the end face gear 2051 to rotate. The end face gear 2051 transmits rotational power to the connecting rod 201 through its stable connection with the connecting rod 201, causing the connecting rod 201 to rotate accordingly. The connecting rod 201 then drives the turntable 202 to rotate, accurately rotating the pump core body 204 to the next working position.
[0025] Specifically, the detection component 206 includes a connecting plate 2061, which is positioned above the turntable 202. A docking cylinder 2062 is fixedly installed at the bottom end of the connecting plate 2061, and the docking cylinder 2062 is located above the pump core body 204. The bottom end of the docking cylinder 2062 is adapted to the top end of the pump core body 204. A communicating air supply pipe 2063 is installed on the outer wall of the docking cylinder 2062, and a pressure sensor is installed in the inner cavity of the air supply pipe 2063. A lifting drive component is connected to one side of the connecting plate 2061 to drive the docking cylinder 2062 to move downwards and completely. The top of the pump core body 204 under test is covered to form a sealed chamber. The lifting drive moves the connecting plate 2061 down, and the connecting plate 2061 moves the air supply pipe 2063 down. The inner cavity of the docking cylinder 2062 completely covers the top of the pump core body 204 under test to form a sealed chamber. The air supply pipe 2063 is connected to an external air supply device such as an air compressor. This is existing technology and will not be described in detail here. Air is filled into the chamber, and the pressure sensor monitors the pressure change in real time. The inner cavity of the docking cylinder 2062 is equipped with a rubber sealing ring to ensure sealing when covering the top of the pump core body 204 under test.
[0026] Specifically, the lifting drive component includes a vertical plate 2064, which is fixedly installed on the top of the worktable 1. A groove 2065 is provided on one side of the vertical plate 2064, and a lead screw 2066 is rotatably connected to the inner cavity of the groove 2065. A slider 2067 is threadedly connected to the outer wall of the lead screw 2066, and the slider 2067 is vertically slidably connected to the groove 2065. One side of the slider 2067 is fixedly connected to the side wall of the connecting plate 2061. A second motor 2068 is fixedly installed on the top of the vertical plate 2064, and the output end of the second motor 2068 is connected to the lead screw 2065. The top of 66 is fixedly connected. The second motor 2068 is started. The second motor 2068 rotates forward, driving the lead screw 2066 to rotate. The slider 2067, which is threaded on the surface of the lead screw 2066, moves down along the slide groove 2065 under the limit of the slide groove 2065. The slider 2067 drives the connecting plate 2061 to move down. The connecting plate 2061 drives the docking cylinder 2062 to move down and cover the top of the pump core body 204 under test. After the test is completed, the second motor 2068 reverses and the docking cylinder 2062 rises and resets, preparing for the test of the next pump core body 204 under test.
[0027] Specifically, the workbench 1 includes a controller 101, which is fixedly installed on the side wall of the workbench 1. The controller 101 is electrically connected to the air pressure sensor, the first motor 2052, and the second motor 2068. The workbench 1 also includes an alarm light 102, which is fixedly installed on the top of the workbench 1. The alarm light 102 is electrically connected to the controller 101. The controller 101 receives the air pressure sensor signal. If the air pressure drop exceeds the threshold, a leak is determined. The controller 101 sends a signal to the alarm light 102, and the alarm light 102 flashes at a high frequency to indicate that the pump core body 204 at the current workstation is unqualified. It also controls the docking cylinder 2062 to move upward and starts the first motor 2052 to switch to the next pump core body 204 to be tested.
[0028] The workbench 1 also includes an annular groove 103, which is opened at the top of the workbench 1. The inner cavity of the annular groove 103 is symmetrically connected with pulleys 104, and the tops of the two sets of pulleys 104 are fixedly connected to the bottom of the turntable 202. When the turntable 202 rotates, the turntable 202 drives the pulleys 104 to roll along the annular groove 103, dispersing the load of the turntable 202 and preventing the connecting rod 201 from deflecting and causing the displacement of the pump core body 204 under test, which would affect the detection.
[0029] During operation, the second motor 2068 is started, and its forward rotation drives the lead screw 2066 to rotate. The slider 2067, which is threaded to the surface of the lead screw 2066, moves downward along the slide groove 2065 under the limit of the slide groove 2065. The slider 2067 drives the connecting plate 2061 to move downward, and the connecting plate 2061 drives the air supply pipe 2063 to move downward. The inner cavity of the docking cylinder 2062 completely covers the top of the pump core body 204 under test, forming a sealed chamber. The air supply pipe 2063 is connected to an external air supply device to fill the chamber with air. The air pressure sensor monitors the pressure change in real time. The controller 101 receives the air pressure sensor signal. If the air pressure drop exceeds the threshold, a leak is determined. The controller 101 sends a signal to the alarm light 102, and the alarm light 102 flashes at a high frequency, indicating that the pump core body 204 at the current station is unqualified. The controller also controls the docking cylinder 2062 to move upward and starts the first motor 2052 to switch to the next pump core body 204 under test.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
