Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of new energy automobile parts production, in particular to a stacked oil cooler cover plate assembly inspection fixture. Background Art
[0002] The stacked oil cooler is a cooler for the gearbox oil, which is usually directly installed on the gearbox to dissipate the oil. The structure of the stacked oil cooler generally includes a cover plate, ribs, corrugated plates, brackets, etc. When assembling, various plates are first stacked layer by layer, and then the sealing ring, cover plate assembly and other parts are assembled. After the assembly is completed, the whole stacked oil cooler is sealed by vacuum brazing to obtain a complete stacked oil cooler.
[0003] Before assembling the various parts of the stacked oil cooler, the production accuracy must be tested first. The cover plate assembly of the stacked oil cooler is as follows: Figure 1 , Figure 2 As shown, its structure includes a cover plate 3, two nozzles 1 with different directions but the same structure are arranged at both ends of the cover plate 3, and a bracket 2 is arranged beside one of the nozzles. As shown in the figure, the bracket 2 and the nozzle 1 have different heights and angles. The dimensions between parts are mostly spatial dimensions, which are difficult to measure with simple tools such as calipers and angle rulers. Not only is the measurement efficiency slow, but the accuracy is also insufficient.
[0004] Therefore, it is necessary to design a test fixture for testing the cover plate assembly of the stacked oil cooler to improve the efficiency and accuracy of its testing. Utility Model Content
[0005] The utility model aims to provide a stacked oil cooler cover plate assembly inspection tool to solve the technical problems of low efficiency and low accuracy in measuring the cover plate assembly of the stacked oil cooler using simple tools such as calipers and angle rulers in the prior art mentioned above.
[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a stacked oil cooler cover plate assembly inspection fixture, including a base, a positioning groove having the same size and thickness as the cover plate is opened on the upper surface of the base, a first detection mechanism having the same height as the nozzle is provided next to the positioning groove on the base, and the angle between the first detection mechanism and the central axis of the cover plate is consistent with the angle between the nozzle and the central axis of the cover plate, and a second detection mechanism is also provided on the base, and the angle between the second detection mechanism and the central axis of the cover plate is consistent with the angle between the bracket and the central axis of the cover plate.
[0007] The beneficial effects of this embodiment are:
[0008] The present application designs a positioning groove, a first detection mechanism and a second detection mechanism. During detection, it is only necessary to place the cover plate assembly in the positioning groove. Since the size and thickness of the positioning groove are consistent with those of the support, the upper surface of the support is flush with the upper surface of the base and is limited in the positioning groove. The height angle of the first detection mechanism is consistent with that of the nozzle, and the angle of the second detection mechanism is consistent with that of the bracket. Therefore, it is only necessary to use the first detection mechanism and the second detection mechanism to overlap the nozzle and the bracket to complete the detection of the nozzle and the bracket, thereby determining whether they are qualified. Compared with the detection in the prior art using simple tools such as calipers and angle rulers, this method is more efficient and accurate.
[0009] Furthermore, the first detection mechanism includes a detection pin that can be pushed into the nozzle for detection, and the detection pin is provided with a reset spring. The reset spring makes the detection pin more convenient to use without manual reset.
[0010] Furthermore, the detection pin is provided with an anti-drop screw to prevent the detection pin from falling off. The anti-drop screw ensures that the detection pin will not slip off and be lost.
[0011] Furthermore, the second detection mechanism includes a bracket detection fork which can detect the angle of the bracket by utilizing the fork body opening.
[0012] Furthermore, a bracket detection base is provided on the base, and the bracket detection fork is rotatably connected to the bracket detection base. The rotation method facilitates lifting the bracket detection fork and placing the cover plate assembly in the positioning groove.
[0013] Furthermore, the base is also provided with a quick clamp that can tighten the cover assembly in the positioning groove. The quick clamp can fix the cover assembly to prevent the bracket from shaking during the inspection process, causing unnecessary collision between the inspection mechanism and the qualified cover assembly, affecting its quality.

[0018] The following is further described in detail through specific implementation methods:
[0019] The figure marks in the drawings of the specification include: nozzle 1, bracket 2, cover plate 3, base 4, first detection mechanism 5, detection pin 51, reset spring 511, detection support 52, anti-slip screw 53, quick clamp 6, transverse clamp 61, clamp shaft 611, fixed threaded pin 62, fixed block 63, tightening rotating column 64, second detection mechanism 7, bracket detection fork 71, detection fork shaft 72, positioning groove 8.
[0020] Implementation example Figures 1 to 4 As shown: A stacked oil cooler cover plate assembly inspection fixture includes a base 4, the base 4 is as shown Figure 3 As shown, a metal plate structure has four supporting feet arranged on the lower surface of the four corners of the base 4, and the supporting feet are fixed by bolts penetrating the base 4.
[0021] A positioning groove 8 is set in the middle of the upper surface of the base 4. The inner contour of the positioning groove 8 is consistent with the outer contour of the cover plate 3, and the size and thickness of the positioning groove 8 are consistent with those of the cover plate 3. Therefore, when the cover plate assembly is placed in the positioning groove 8, the cover plate 3 of the cover plate assembly is just completely located in the positioning groove 8, and the upper surface of the cover plate 3 is flush with the upper surface of the base 4.
[0022] by Figure 3 Direction is a description direction. The first detection mechanism 5 is set at the left end of the positioning groove 8 and the upper right side of the positioning groove 8. Therefore, two first detection mechanisms 5 are provided, and their structures are exactly the same. The angle between the first detection mechanism 5 and the central axis of the positioning groove 8 corresponds to the angle between the central axis of the different nozzles 1 and the central axis of the length direction of the cover plate 3. Figure 2 It can be seen that the included angles between the two nozzles 1 on the cover plate assembly and the longitudinal center axis of the cover plate 3 are 69.5° and 91° respectively. Figure 3 The angle between the first detection mechanism 5 at the middle left end and the central axis of the positioning groove 8 is 91°, and the angle between the first detection mechanism 5 at the upper right end and the central axis of the positioning groove 8 is 69.5°; and its height from the upper surface of the base 4 is consistent with the height of the nozzle 1 from the upper surface of the cover plate 3.
[0023] Taking the first detection mechanism on the left side as an example, the first detection mechanism 5 includes a detection support 52, which is an inverted L-shaped structure, wherein the horizontal part of the inverted L-shaped structure is fixed to the base 4 by bolts, and a through hole is opened in the vertical part of the detection support 52, in which a detection pin 51 is accommodated, and the left end of the detection pin 51 is provided with an end head with a diameter larger than the pin body, and the right end is the pin body. The pin body of the detection pin 51 can slide in the through hole, and a reset spring 511 is provided on the pin body of the detection pin 51, and the reset spring 511 resists the end head of the detection pin 51 and the detection support 52, so that when the detection pin 51 is applied with external force, it can move to the right, and when the external force is removed, the reset spring 511 can reset the pin shaft 51. An anti-drop screw 53 is provided at the upper end of the detection support 52. The anti-drop screw 53 penetrates the upper end of the detection support 52 and contacts the detection pin 51. An anti-drop groove is provided on the upper surface of the detection pin 51. The anti-drop screw 53 can extend into the anti-drop groove to prevent the detection pin 51 from falling off when the reset spring 511 is reset. The pin body diameter of the detection pin 51 is consistent with the inner diameter of the nozzle 1. Therefore, when testing, it is only necessary to push the detection pin 51. If it can be inserted into the nozzle 1, it is qualified. If not, it is unqualified. The operation is simple and the accuracy is high.
[0024] A quick clamp 6 is provided at the rear side of the first detection mechanism 5. The quick clamp 6 includes a clamp base. A transverse clamp 61 is connected to the clamp base via a clamp shaft 611, so that the transverse clamp 61 can rotate around the clamp shaft 611. A fixed threaded pin 62 is connected to the right end of the transverse clamp 61 via a bolt. A fixed block 63 having a diameter larger than the fixed threaded pin 62 is provided at the lower end of the fixed threaded pin 62, and the fixed block 63 and the fixed threaded pin 62 are an integrally processed structure. A vertical support is also provided in the clamp base in the vertical direction. The vertical support is composed of two pieces that are overlapped and connected by bolts. A space is opened in the middle so that the transverse clamp 61 can pass through the middle. A tightening rotating column 64 is hinged at the upper end of the vertical support, so that the tightening rotating column 64 can rotate at the upper end of the vertical support. When in use, first rotate the rotating column 64 to make it horizontal, then lift the horizontal clamp 61, place the cover assembly in the positioning groove 8, and then release the horizontal clamp 61. Under the action of gravity, the horizontal clamp 61 presses the cover assembly downward. At this time, rotate the rotating column 64 to the vertical direction, and press the horizontal clamp 61 to complete the fixed restriction of the cover assembly.
[0025] A second detection mechanism 7 is also provided at the upper right side of the base 4. The second detection mechanism 7 includes a bracket detection fork 71, a bracket detection base, and a detection fork shaft 72. The bracket detection base is directly welded to the base 4, and the bracket detection fork 71 is hinged to the bracket detection base by the detection fork shaft 72. The opening width of the fork body of the bracket detection fork 71 is consistent with the width of the bracket, and the angle between the central axis of the bracket detection fork 71 and the central axis of the positioning groove 8 is consistent with the angle between the central axis of the bracket 2 and the cover plate 3 along the length direction. Therefore, during the inspection, it is only necessary to rotate the bracket detection fork 71. When the opening of the bracket detection fork 71 can just catch the two sides of the bracket 2, it means that the angle detection of the bracket 2 is qualified. If not, it is unqualified. The operation is simple and efficient.
[0026] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
