Description

Technical Field

[0001] The present disclosure belongs to the technical field of cooler installation and detection equipment, and specifically relates to a platform for detecting the flatness of the end cover and the angle of the water pipe of a high-voltage battery cooler. Background Technology

[0002] The high-voltage battery cooler is a type of heat exchanger that combines the functions of an evaporator and a heat exchanger. It is a key component that couples the battery liquid cooling circuit and the cabin air conditioning circuit. It is also one of the incremental components of the thermal management system of new energy vehicles using a liquid cooling solution;

[0003] In the prior art, high-voltage battery cooling systems often require the water outlet pipe to be riveted to the cooler end cover to ensure the stable operation and safety of the cooling system; when a 90° bent water pipe is riveted to the end cover, after one end of the water pipe is anchored on the end cover, the other end extends horizontally directly above the end cover and is placed vertically with any peripheral wall of the end cover, that is, the plane where the central axis of the water pipe is located is vertically or parallel to the side walls around the end cover; however, during the riveting process, the water pipe may be misaligned around the central axis of the riveting hole, causing the riveted water pipe to tilt and misalign with the peripheral wall of the end cover, which may easily lead to unqualified riveting installation of the water pipe; therefore, after the water pipe is riveted, it is usually necessary to detect the angle between the water pipe and the peripheral wall of the end cover, but since the water pipe and the peripheral wall of the end cover are not in the same plane, it is inconvenient to detect the angle between the peripheral wall of the end cover and the plane of the water pipe. Contents of utility model

[0004] Aiming at the shortcomings of the prior art, the purpose of the present invention is to provide a platform for detecting the flatness of the end cover and the angle of the water pipe of the high-voltage battery cooler, which solves the problem in the prior art that it is inconvenient to detect the angle between the end cover peripheral wall and the water pipe plane.

[0005] The purpose of this disclosure can be achieved through the following technical solutions:

[0006] Detect the end cover flatness and water pipe angle platform of the high-voltage battery cooler, including the support platform;

[0007] A testing chamber with an opening on one side is fixed on the upper end of the support platform;

[0008] A vertically placed slide is provided in the detection chamber, a horizontally placed telescopic cylinder is fixed on the slide, a moving bar parallel to the slide is fixed on the other end of the telescopic cylinder, a detection block is provided on the side of the moving bar away from the slide, both sides of the detection block close to or away from the moving bar are placed parallel to the moving bar, a pair of telescopic rods facing horizontally to the detection block are fixed on the moving bar, the ends of the telescopic rods close to the detection block are rotatably hinged with connectors, and the connectors are fixed to the detection block;

[0009] The telescopic rods are all hollow inside and open at both ends. A laser rangefinder is provided at one end of each telescopic rod close to the moving strip, and the laser rangefinder is used to measure the distance between the corresponding connecting piece and the moving strip.

[0010] The principle and effect of the above technical solution are as follows:

[0011] When the telescopic cylinder is opened to push the moving strip, the telescopic rods, the connecting pieces and the detection block, both ends of the detection block away from the moving strip side are kept in contact with the water pipe. At this time, the distances between the corresponding connecting pieces and the moving strip are measured by the two laser rangefinders. If the distances measured by the two laser rangefinders are equal, it indicates that the water pipe does not deflect out of position around the central axis of the riveting hole during the riveting process. If the distances measured by the two laser rangefinders are not equal, it indicates that the water pipe deflects out of position around the central axis of the riveting hole during the riveting installation of the water pipe, and the riveting installation of the water pipe is unqualified. Moreover, the difference between the two distances can indirectly reflect the angle between the side wall of the end cover and the plane where the axis of the water pipe is located, realizing the detection of the angles of the end cover and the water pipe.

[0012] Each telescopic rod includes a sleeve rod fixed on the moving strip. A sliding rod is arranged inside each sleeve rod in a sliding connection. The connecting piece is rotatably hinged to one end of the sliding rod away from the moving strip. A disc is fixedly sleeved on each sliding rod. The disc is located between the connecting piece and the sleeve rod. A spring is sleeved on each telescopic rod. Both ends of the spring are respectively fixed to the disc and the moving strip, and the spring is always in a compressed state.

[0013] A horizontally placed groove is formed on one side surface of the detection block away from the moving strip, and the cross section of the groove is an isosceles triangle.

[0014] A two-way sliding table is provided on any side wall of the detection chamber. The two-way sliding table is connected to the sliding plate and is used to drive the sliding plate to move in the vertical plane where it is located.

[0015] A placement plate is fixed on the inner bottom surface of the detection chamber. One end of the placement plate is fixed with a vertically placed baffle, and the plane where the baffle is located is perpendicular to the plane where the sliding plate is located.

[0016] A chute is formed on the upper end surface of the placement plate. The chute is perpendicular to the telescopic rod. A clamping plate parallel to the baffle is provided on the placement plate. The lower end of the clamping plate extends into the chute and is slidably clamped with it. A driving member is connected to the clamping plate, and the driving member is used to drive the clamping plate to approach or move away from the baffle.

[0017] The driving member includes a screw rod rotatably connected to the baffle. The screw rod is coaxially placed with the chute. The screw rod is located in the chute and is rotatably connected to the chute wall. The screw rod passes through the clamping plate and is threadedly connected to it. A rotating motor for driving the screw rod to rotate is installed on the baffle.

[0018] The explanations of the nouns, conjunctions or adjectives involved in the above technical solution are as follows:

[0019] Connection: It refers to the process of connecting two separated profiles or parts into a complex part or component using fasteners such as screws, bolts, and rivets.

[0020] Sliding connection: Two objects are in contact but not fixed, and they can slide relative to each other.

[0021] Advantages of the present disclosure:

[0022] 1. By pushing the moving bar, telescopic rod, connecting piece, and detection block with a telescopic cylinder, both ends of the detection block far from the moving bar side are kept in contact with the water pipe. At this time, the distances between the corresponding connecting pieces and the moving bar are measured by two laser rangefinders; if the distances measured by the two laser rangefinders are equal, it indicates that the water pipe does not deflect out of position around the central axis of the riveting hole during the riveting process; if the distances measured by the two laser rangefinders are not equal, it indicates that the water pipe deflects out of position around the central axis of the riveting hole during the riveting and installation process of the water pipe, and the riveting and installation of the water pipe is unqualified. Moreover, the difference between the two distances can indirectly reflect the angle between the side wall of the end cover and the plane where the axis of the water pipe is located, realizing the detection of the angles of the end cover and the water pipe.

[0023] 2. Through the setting of the disc and the spring, the detection block far from the side of the moving bar can be kept in close contact with the water pipe. At the same time, with the setting of the groove on the detection block, the contact stability when the detection block contacts the water pipe for detection can be improved, and it can be applicable to the detection of water pipes with various different diameters; and it is combined with the bidirectional sliding table to drive the sliding plate to adjust the position in the vertical plane, facilitating the detection of the angles between the water pipes at different heights and different positions on different specifications of end covers.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0031] Herein, in combination with Figures 1 to 5 to describe an embodiment of detecting the flatness of the end cover and the water pipe angle platform of a high-voltage battery cooler. Specifically, the device for detecting the flatness of the end cover and the water pipe angle platform of the high-voltage battery cooler is configured as a split structure, which has components such as a detection chamber 200, a slide plate 3, a telescopic cylinder 4, a moving bar 5, a detection block 6, a telescopic rod 7, a connecting block 8, and a laser rangefinder. When the telescopic cylinder 4 is opened to push the moving bar 5, the telescopic rod 7, the connecting member 8, and the detection block 6, both ends of the detection block 6 away from the moving bar 5 are kept in contact with the water pipe. At this time, the distances between the corresponding connecting blocks 8 and the moving bar 5 are measured by two laser rangefinders. If the distances measured by the two laser rangefinders are equal, it indicates that the water pipe does not deflect around the central axis of the riveting hole during the riveting process. If the distances measured by the two laser rangefinders are not equal, it indicates that the water pipe deflects around the central axis of the riveting hole during the riveting installation process, and the riveting installation of the water pipe is unqualified. Moreover, the difference between the two distances can indirectly reflect the angle between the side wall of the end cover and the plane where the axis of the water pipe is located, realizing the detection of the circumferential wall of the end cover and the water pipe angle.

[0032] Please refer to Figures 1 to 5 , a device for detecting the flatness of the end cover and the water pipe angle platform of a high-voltage battery cooler, including a support table 100:

[0033] A detection chamber 200 with an open side is fixed at the upper end of the support table 100;

[0034] A vertically placed slide plate 3 is arranged in the detection chamber 200. A horizontally placed telescopic cylinder 4 is fixed on the slide plate 3. The other end of the telescopic cylinder 4 is fixed with a moving bar 5 parallel to the slide plate 3. A detection block 6 is arranged on the side of the moving bar 5 away from the slide plate 3. Both side surfaces of the detection block 6 close to or away from the moving bar 5 are placed parallel to the moving bar 5. A pair of telescopic rods 7 horizontally facing the detection block 6 are fixed on the moving bar 5. The ends of the telescopic rods 7 close to the detection block 6 are rotatably hinged with connecting blocks 8, and the connecting blocks 8 are both fixed to the detection block 6;

[0035] The telescopic rods 7 are both hollow inside and open at both ends. Laser rangefinders are arranged at one ends of the telescopic rods 7 close to the moving bar 5, and the laser rangefinders are used to measure the distances between the corresponding connecting blocks 8 and the moving bar 5.

[0036] The detection bin 200 is a device for storing, testing, or observing the object to be tested. It can be made of materials such as plastic-resistant or stainless steel. Its function is to protect the object to be tested from external interference and provide a safe environment for testing, observing, or processing, so as to ensure accurate data collection and analysis.

[0037] The telescopic cylinder 4 uses lightweight aluminum alloy to ensure smooth movement and durability; the diameter of the telescopic cylinder 4 usually determines the magnitude of its output force and the ability to withstand pressure. Common diameters are 25mm, 32mm, 40mm, etc.

[0038] The laser rangefinder is preferably a phase-type laser rangefinder. It uses a laser beam for amplitude modulation and measures the phase delay generated by the modulated light traveling back and forth along the measuring line once. Then, according to the wavelength of the modulated light, the distance represented by this phase delay is calculated, that is, the time required for the light to travel back and forth along the measuring line is measured indirectly.

[0039] The water pipe bend extends along any side wall direction of the end cover. The end cover is horizontally placed in the detection bin 200, and this side wall is placed parallel to the moving strip 5. The side wall towards which the water pipe bend end faces is placed perpendicular to the moving strip 5. The telescopic cylinder 4 is activated to push the moving strip 5, the telescopic rod 7, the connecting piece 8, and the detection block 6, so that the detection block 6 continuously approaches the water pipe. The detection block 6 and the water pipe are mutually extruded, causing the two telescopic rods 7 to contract, and both ends of the detection block 6 away from the moving strip 5 side remain in contact with the water pipe. At this time, the distances between the corresponding connecting pieces 8 and the moving strip 5 are measured by the two laser rangefinders; if the distances measured by the two laser rangefinders are equal, it indicates that the installation angle of the water pipe is accurate and the water pipe does not deviate or deflect around the central axis of the riveting hole during the riveting process; if the distances measured by the two laser rangefinders are not equal, it indicates that the water pipe deviates or deflects around the central axis of the riveting hole during the riveting installation process, and the riveting installation of the water pipe is unqualified. Moreover, the difference in the distances measured by the two laser rangefinders can indirectly reflect the angle between the side wall of the end cover and the plane where the axis of the water pipe is located, realizing the convenient detection of the angles of the end cover and the water pipe.

[0040] In order to facilitate the detection, both ends of the detection block 6 far from the side of the moving bar 5 can maintain contact with the water pipe. The telescopic rod 7 includes a sleeve rod fixed to the moving bar 5. A sliding rod is slidably connected inside the sleeve rod. The connecting piece 8 is rotatably hinged to the end of the sliding rod far from the moving bar 5. Discs 9 are fixedly sleeved on the sliding rods. The disc 9 is located between the connecting piece 8 and the sleeve rod. Springs 10 are sleeved on the telescopic rods 7. Both ends of the spring 10 are respectively fixed to the disc 9 and the moving bar 5. The spring 10 is always in a compressed state. When the detected water pipe is misaligned and deflected, the detection block 6 approaches the water pipe and compresses the telescopic rod 7 and the spring 10. At the same time, the detection block 6 drives the connecting pieces 8 at both ends to rotate and hinge with the corresponding telescopic rod 7. At the same time, with the elastic force of the spring 10, the spring 10 pushes the disc 9 and drives the sliding rod, the connecting piece 8 and the detection block 6, so that the side of the detection block 6 far from the moving bar 5 remains in close contact with the water pipe.

[0041] A horizontally placed groove 61 is formed on one side of the detection block 6 far from the moving bar 5. The cross-section of the groove 61 is an isosceles triangle. By fitting the groove 61 with the peripheral wall of the horizontal section after the water pipe is bent, the contact stability when the detection block 6 contacts the water pipe for detection is improved. And the setting of the isosceles triangle groove 61 can be applicable to the detection of water pipes with various different diameters.

[0042] A two-way slide 11 is provided on any side wall of the detection bin 200. The two-way slide 11 is connected to the slide plate 3 and is used to drive the slide plate 3 to move in the vertical plane where it is located. By driving the slide plate 3 to adjust its position in the vertical plane through the two-way slide 11, it is convenient to be applicable to the detection of the angles between water pipes at different heights and different positions on end covers of different specifications.

[0043] In order to facilitate the precise control of the placement angle of the end cover during detection, a placement plate 12 is fixed on the inner bottom surface of the detection bin 200. One end of the placement plate 12 is fixed with a vertically upward placed baffle 13. The plane where the baffle 13 is located is perpendicular to the plane where the slide plate 3 is located. During detection, by fitting any side wall of the end cover perpendicular to the extending direction of the bent end of the water pipe with the baffle 13, the precise control of the placement angle of the end cover during detection can be realized.

[0044] In order to facilitate the stable clamping of the end cover and prevent the end cover from slipping during the process of the telescopic cylinder 4 pushing the detection block 6 to fit the water pipe, a chute 121 is formed on the upper end surface of the placement plate 12. The chute 121 is perpendicular to the telescopic rod 7. A clamping plate 14 parallel to the baffle 13 is provided on the placement plate 12. The lower end of the clamping plate 14 extends into the chute 121 and is slidably clamped with it. A driving member is connected to the clamping plate 14. The driving member is used to drive the clamping plate 14 to approach or move away from the baffle 13. Place the end cover between the baffle 13 and the clamping plate 14, and drive the clamping plate 14 to approach the baffle 13 through the driving member to realize the stable clamping of the end cover.

[0045] The driving member includes a screw rod 15 rotatably connected to the baffle 13. The screw rod 15 is coaxially placed with the chute 121. The screw rod 15 is located in the chute 121 and rotatably connected to the chute wall of the chute 121. The screw rod 15 passes through the clamping plate 14 and is threadedly connected thereto. A rotating motor 151 for driving the screw rod 15 to rotate is installed on the baffle 13. The rotating motor 151 drives the screw rod 15 to drive the clamping plate 14 for screw transmission, thereby controlling the clamping plate 14 to move away from or close to the baffle 13.
