Technical Field

[0001] This utility model relates to the field of electric pump technology, specifically to an electric pump testing device. Background Technology

[0002] The electronically controlled pump air tightness tester is a professional testing device specifically used to test the air tightness of electronically controlled pumps (such as automotive electronic fuel pumps, industrial electric hydraulic pumps, and circulating pumps for liquid cooling systems in new energy vehicles). During use, the operator places the electronically controlled pump stably on the positioning reference in the test area, ensuring that the interface of the pump body is precisely aligned with the sealing position of the clamp. Then, the control device lowers the clamp to press down on the pump body for testing.

[0003] In the existing technology, when using an electrically controlled pump airtightness tester, the operator needs to manually place the electrically controlled pump in the test area, and then control the test component of the tester to press down on the electrically controlled pump to carry out the test operation. During the operation, the electrically controlled pump needs to be manually removed. If the operator does not remove his hands in time after the equipment is started, or if the workpiece is not placed stably and the test component shifts when it is pressed down, it may cause safety accidents such as pinching or crushing injuries.

[0004] Therefore, it is necessary to propose an electronically controlled pump testing device to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide an electric pump testing device to solve the problem mentioned in the background art that the electric pump airtightness tester requires the operator to manually remove the electric pump. If the operator does not remove his hands in time after the equipment is started, or if the workpiece is not placed stably and the test component shifts when it is pressed down, it may cause safety accidents such as pinching or crushing injuries.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrically controlled pump testing device, comprising an electrically controlled pump airtightness tester and an electrically controlled pump, wherein the electrically controlled pump airtightness tester is provided with a detection tube; two guide plates are symmetrically installed on the electrically controlled pump airtightness tester, and a feeding structure is connected to the two guide plates; a linkage plate and a U-shaped baffle are connected to the feeding structure; the linkage plate is installed on one side of the U-shaped baffle; a push-pull structure is connected to the linkage plate; and a limit structure is connected to the U-shaped baffle.

[0007] Preferably, the feeding structure includes a U-shaped slide block, which is slidably installed between two guide plates, and a U-shaped baffle is installed above the U-shaped slide block. A positioning groove is provided inside the U-shaped slide block, and an electric control pump is movably installed in the positioning groove.

[0008] Preferably, the guide plate has two horizontal grooves, two inclined grooves and two horizontal grooves inside, and two sliding shafts are installed on one side of the U-shaped slide, with the two sliding shafts movably installed in the two horizontal grooves.

[0009] Preferably, the airtightness tester for the electrically controlled pump is equipped with a support rod, and an arc-shaped positioning plate is installed at one end of the support rod, the arc-shaped positioning plate corresponding to the electrically controlled pump.

[0010] Preferably, the push-pull structure includes a multi-stage electric push rod, which is mounted on an electric control pump airtightness tester. A push-pull plate is installed at the output end of the multi-stage electric push rod, and the push-pull plate is slidably mounted on the linkage plate.

[0011] Preferably, the push-pull plate has a sliding groove inside, and the linkage plate is slidably installed inside the linkage plate.

[0012] Preferably, the limiting structure includes a slide rod, which is slidably installed inside the U-shaped baffle. One end of the slide rod is fitted with a clamp, and a spring is slidably sleeved on the slide rod. One end of the spring is installed on the U-shaped baffle, and the other end of the spring is installed on the clamp.

[0013] Preferably, a limit baffle is installed at one end of the slide rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In use, the electric control pump can be placed in the positioning groove, and then the multi-stage electric push rod can be turned on to control the movement of the U-shaped slide. When the U-shaped slide moves, it will drive the electric control pump to move above the detection tube. The continuously moving U-shaped slide will be lowered by the sliding shaft. With the positioning and blocking of the arc-shaped positioning plate, the electric control pump can be placed on the detection tube. Then the electric control pump air tightness tester can be turned on to perform an air tightness test on the electric control pump. After the test is completed, the multi-stage electric push rod can be used to control the U-shaped slide to reset. When the U-shaped slide resets, it will rise again and drive the electric control pump to get off the detection tube. Thus, the operation of picking up and putting down the electric control pump does not require the operator to put their hands in the test area of ​​the electric control pump air tightness tester, which further improves the safety of the operation.

[0016] (2) When the U-shaped slide moves the electric control pump to the test tube, if the U-shaped slide is continuously controlled to move, the U-shaped baffle will protect the side of the electric control pump. At the same time, the clamp will press on the electric control pump. By using the squeezing cooperation between the arc-shaped positioning plate and the clamp, the electric control pump can be prevented from falling off the test tube, thus improving the stability of the electric control pump during testing and preventing it from deviating.

[0026] 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.

[0027] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: an electrically controlled pump testing device, including an electrically controlled pump airtightness tester 100 and an electrically controlled pump 102. The electrically controlled pump airtightness tester 100 is equipped with a detection tube 101. Two guide plates 200 are symmetrically installed on the electrically controlled pump airtightness tester 100, and a feeding structure is connected to the two guide plates 200. The feeding structure is used to push the electrically controlled pump 102 to the test position of the detection tube 101. A linkage plate 300 and a U-shaped baffle 400 are connected to the feeding structure. The linkage plate 300 is installed on one side of the U-shaped baffle 400, and a push-pull structure is connected to the linkage plate 300. The push-pull structure is used to control the movement of the feeding structure, thus eliminating the need for manual pushing of the electrically controlled pump 102. A limiting structure is connected to the U-shaped baffle 400, which is used to clamp the electrically controlled pump 102 during testing, improving stability.

[0028] Furthermore, the feeding structure includes a U-shaped slide 201, which is slidably installed between two guide plates 200. A U-shaped baffle 400 is installed above the U-shaped slide 201. A positioning groove 202 is provided inside the U-shaped slide 201. An electric control pump 102 is movably installed in the positioning groove 202. The electric control pump 102 can be placed in the positioning groove 202. When the U-shaped slide 201 moves, it will drive the electric control pump 102 to move, thereby moving the electric control pump 102 above the detection tube 101.

[0029] Furthermore, the guide plate 200 has two horizontal grooves 203, two inclined grooves 204 and two horizontal grooves 205 inside. Two sliding shafts 206 are installed on one side of the U-shaped slide 201. The two sliding shafts 206 are movably installed in the two horizontal grooves 203 respectively. During the continuous movement of the U-shaped slide 201, it will drive the electric control pump 102 to move above the detection tube 101. At the same time, it will cause the sliding shafts 206 to move into the inclined grooves 204 and horizontal grooves 205 in sequence. During this process, the U-shaped slide 201 will descend, causing the U-shaped slide 201 to drive the electric control pump 102 to descend above the detection tube 101.

[0030] Furthermore, a support rod 207 is installed on the airtightness tester 100 of the electric pump. An arc-shaped positioning plate 208 is installed at one end of the support rod 207. The arc-shaped positioning plate 208 corresponds to the electric pump 102. The arc-shaped positioning plate 208 can be used to position and block the electric pump 102 when it moves, so as to ensure that the electric pump 102 can be aligned with the test tube 101.

[0031] Furthermore, the push-pull structure includes a multi-stage electric push rod 301, which is mounted on the electric control pump airtightness tester 100. A push-pull plate 302 is installed at the output end of the multi-stage electric push rod 301. The push-pull plate 302 is slidably mounted on the linkage plate 300. Activating the multi-stage electric push rod 301 can pull the push-pull plate 302 to move, so that the push-pull plate 302 drives the linkage plate 300 and the U-shaped slide block 201 to move through the slide groove 303.

[0032] Furthermore, the push-pull plate 302 has a sliding groove 303 inside, and the linkage plate 300 is slidably installed in the linkage plate 300. During the lifting and lowering process of the U-shaped slide block 201, the linkage plate 300 will be driven to move accordingly, so that the linkage plate 300 can slide in the sliding groove 303 on the push-pull plate 302.

[0033] Example 2: As Figure 2-6To ensure the stability of the electrically controlled pump 102 during testing, a limiting structure is provided. This limiting structure includes a slide rod 401, which is slidably mounted inside a U-shaped baffle 400. A clamp 402 is mounted on one end of the slide rod 401, and a spring 403 is slidably sleeved on the slide rod 401. One end of the spring 403 is mounted on the U-shaped baffle 400, and the other end is mounted on the clamp 402. A limiting baffle is also installed at one end of the slide rod 401. 404. The moving U-shaped slide 201 will drive the U-shaped baffle 400 to protect both sides of the electric pump 102, and drive the clamp 402 to press on the electric pump 102. The clamp 402 being pressed will drive the slide rod 401 to slide within the U-shaped baffle 400 and compress the spring 403. Under the elastic force of the spring 403, the clamp 402 can press the electric pump 102 onto one side of the arc-shaped positioning plate 208, improving the stability of the electric pump 102. The remaining features are the same as in Embodiment 1.

[0034] The working principle is as follows: (Reference) Figure 1 and Figure 5 In operation, the electric pump 102 is placed in the positioning slot 202. Activating the multi-stage electric push rod 301 pulls the push-pull plate 302, causing it to move via the slide groove 303, which in turn moves the linkage plate 300. This, in turn, moves the U-shaped baffle 400 and the U-shaped slide block 201. The moving U-shaped slide block 201 moves the electric pump 102, and simultaneously moves the two sliding shafts 206 within the corresponding horizontal groove 1 203. During this continuous movement, the electric pump 102 moves above the detection tube 101, and the sliding shafts 206 move sequentially into the inclined groove 204 and the horizontal groove 2 205. This process causes the U-shaped slide block 201 to descend, allowing it to move the electric pump 102... 02 descends above the detection tube 101. The arc-shaped positioning plate 208 positions and blocks the electric pump 102 as it moves, ensuring alignment. At this point, the electric pump 102, blocked by the arc-shaped positioning plate 208, will not continue moving with the U-shaped slide 201. The continuously moving U-shaped slide 201 will then cause the U-shaped baffle 400 to protect both sides of the electric pump 102, and cause the clamp 402 to press against the electric pump 102. The pressure on the clamp 402 will cause the slide rod 401 to slide within the U-shaped baffle 400 and compress the spring 403. Under the elastic force of the spring 403, the clamp 402 will press the electric pump 102 against one side of the arc-shaped positioning plate 208, improving the stability of the electric pump 102. After completion, it is... Figure 3 Once the device is in the correct state, the electric control pump 102 can be installed onto the test tube 101. After that, the electric control pump 102 can be tested for air tightness using the electric control pump air tightness tester 100.

[0035] When the electric pump 102 needs to be removed, the multi-stage electric push rod 301 is controlled to push the push-pull plate 302 to move and reset, thereby driving the linkage plate 300, U-shaped baffle 400 and U-shaped slide 201 to reset, so that the clamp 402 is released from the pressure on the electric pump 102. At the same time, when the U-shaped slide 201 drives the sliding shaft 206 to move sequentially to the inclined groove 204 and the horizontal groove 203, it will rise and reset again. The rising U-shaped slide 201 will lift the electric pump 102 after the test. Then, the continuously resetting U-shaped slide 201 will drive the electric pump 102 to move out of the test position of the electric pump airtightness tester 100, so that the electric pump 102 can be removed later.

[0036] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
