Description

Technical Field

[0001] The utility model belongs to the technical field of automobile joint assembly, and in particular relates to a press-fit structure. Background Art

[0002] With the development of the new energy industry, the performance requirements of new energy batteries are getting higher and higher, and the safety requirements are also increasing. Existing new energy lithium batteries generally self-ignite or explode when the battery cell is overheated or short-circuited. At a certain high temperature, a self-catalytic reaction occurs, resulting in combustion and even explosion. Therefore, the cooling system of new energy batteries is particularly important in actual use.

[0003] like Figure 1 As shown, it is a schematic diagram of the structure of the vehicle end bracket 4. The vehicle end bracket holes 41 are opened at the four corners of the vehicle end bracket 4, which play a role of limiting when assembling the vehicle end bracket 4. There are two groups of vehicle end connection bodies 42, which are fixed on the vehicle end bracket 4 and are used to cover the vehicle end protection pads 43.

[0004] like Figure 2 As shown in FIG. 1 , it is a schematic diagram of the structure of the vehicle end protection pad 43. The vehicle end protection pad 43 is a flexible pad, and a pad hole 44 is opened on the vehicle end protection pad 43. The diameter of the pad hole 44 is smaller than the diameter of the vehicle end connection body 42. When assembling, the vehicle end protection pad 43 is sleeved on the vehicle end connection body 42. Figure 3 As shown, both sides of the vehicle end bracket 4 are covered with vehicle end protection pads 43. After the vehicle end protection pads 43 are assembled, cover plates are fixed on both sides of the vehicle end bracket 4 by screw fastening to cover the vehicle end protection pads 43.

[0040] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0041] like Figure 1 As shown, it is a schematic diagram of the structure of the vehicle end bracket 4. The vehicle end bracket holes 41 are opened at the four corners of the vehicle end bracket 4, which play a role of limiting when assembling the vehicle end bracket 4. There are two groups of vehicle end connection bodies 42, which are fixed on the vehicle end bracket 4 and are used to cover the vehicle end protection pads 43.

[0042] like Figure 2 As shown, it is a schematic diagram of the structure of the vehicle end protection pad 43. The vehicle end protection pad 43 is a flexible pad, and a pad hole 44 is opened on the vehicle end protection pad 43. The diameter of the pad hole 44 is smaller than the diameter of the vehicle end connection body 42. During assembly, the vehicle end protection pad 43 is put on the vehicle end connection body 42.

[0043] like Figure 3 As shown, it is a schematic diagram of the structure after the vehicle-end bracket 4 and the vehicle-end protection pad 43 are assembled together. The vehicle-end protection pads 43 are sleeved on both sides of the vehicle-end bracket 4. After the vehicle-end protection pads 43 are assembled, cover plates are fixed on both sides of the vehicle-end bracket 4 by screw fastening to cover the vehicle-end protection pads 43. After the vehicle-end is assembled, it is plugged into the package end of the automobile connector, so as to be used in the cooling system of the new energy vehicle (the package end is connected to the new energy battery, the vehicle end is connected to the driving device of the vehicle, and the package end and the vehicle end are connected with coolant for cooling the new energy battery).

[0044] like Figure 4-6 As shown, it is a schematic diagram of the press-fit structure of the utility model, which is usually used in the vehicle-end assembly process of the new energy vehicle joint, and is used to set the flexible vehicle-end protection pad 43 on the vehicle-end bracket 4. The press-fit structure includes a feeding component 1, a clamping component 2 and a press-fit component 3. The feeding component 1 is used to convey the vehicle-end bracket 4 and the vehicle-end protection pad 43 to be assembled, and the clamping component 2 is used to clamp the positioning column 215 and insert the positioning column 215 on the vehicle-end connection body 42 of the vehicle-end bracket 4. When the press-fit component 3 presses the vehicle-end protection pad 43, it plays an auxiliary role to avoid the situation where the flexible characteristics of the vehicle-end protection pad 43 cause the assembly to be in place.

[0045] like Figure 7 The figure shows the structure of the feeding assembly 11, which includes a feeding frame 101, a feeding plate 102, a slide rail 103, a slider 104, a linear slide 105, a carrier plate 106, a positioning hole 107, a positioning pin 108, a limiting groove 109, a limiting plate 110, a vehicle end protection pad 111, a vehicle end protection pad groove 112 and a vehicle end bracket pin 113. There are two groups of feeding frames 101, which are fixed on the assembly machine at intervals. The top of the feeding frame 101 is fixed with a slide rail 103, and the slider 104 is slidably installed on the slide rail 103. The feeding plate 102 is fixed on the slider 104, and under the action of the linear slide 105, the feeding plate 102 is driven to make a linear motion along the feeding frame 101.

[0046] The carrier plate 106 is connected to the feed plate 102 via a positioning pin 108. A diagonally arranged positioning hole 107 is provided on the carrier plate 106. A positioning pin 108 matching the positioning hole 107 is fixed on the feed plate 102. The diagonally plug-in fixing method can ensure that the position of the carrier plate 106 relative to the feed plate 102 does not shift, and in the assembly work of the vehicle end bracket 43 with different structures, different carrier plates 106 can be disassembled and replaced to improve the versatility of the structure.

[0047] The vehicle end protection pad 111 is fixed on the carrier plate 106 , and the vehicle end protection pad groove 112 is opened on the vehicle end protection pad 111 . The vehicle end protection pad groove 112 matches the shape of the vehicle end protection pad 43 . Before assembly, the operator places the vehicle end protection pad 43 on the vehicle end protection pad 111 .

[0048] The vehicle-end bracket pin 113 is fixed on the carrier plate 106 and matches the position and size of the vehicle-end bracket hole 41. Before assembly, the operator places the vehicle-end bracket 43 on the carrier plate 106 (the vehicle-end bracket hole 41 of the vehicle-end bracket 43 is inserted into the vehicle-end bracket pin 113).

[0049] like Figure 8 As shown, arc-shaped limiting grooves 109 are provided on both sides of the carrier plate 106, and the limiting plate 110 is rotatably mounted on the feed plate 102 through a rotating shaft and matched with the limiting groove 109. From a top view, the limiting plate 110 is a shape remaining after a part of the arc is cut off from a circle, and the diameter of the limiting plate 110 is the same as the diameter of the limiting groove 109. From a top view, the limiting plate 110 and the limiting groove 109 complement each other to form a circle.

[0050] When the limiting plate 110 is rotated to the limiting groove 109, the carrier plate 106 is pressed by the limiting plate 110 and relatively fixed; when the notch of the limiting plate 110 is rotated to the limiting groove 109, due to the lack of the pressing effect of the limiting plate 110, the carrier plate 106 can be removed from the feed plate 102 at this time, thereby meeting the assembly work of the vehicle end bracket 43 with different structures and improving the versatility.

[0051] like Fig. 9As shown, it is a cross-sectional view of the clamping assembly 2, which is used to clamp the positioning column 215 and insert it on the vehicle end connecting body 42. The clamping assembly 2 includes a gantry 201, a first lifting cylinder 202, a first guide sleeve 203, a first guide column 204, a clamping plate 205, a finger cylinder 206, an initial positioning plate 207, an initial positioning hole 208, a clamping block 209, a slot 210, a boss 211, a clamping plate 212, a clamping groove 213, a groove 214, a positioning column 215, a guide portion 216 and an avoidance hole 217. The gantry 201 is fixed on the assembly machine and is set up above the feeding assembly 1, and is used to fix and install the clamping assembly 2 and the press-fitting assembly 3.

[0052] The first guide sleeve 203 is embedded in the top of the gantry 201, the first guide column 204 passes through the first guide sleeve 203, and the clamping plate 205 is fixed to the bottom of the first guide column 204. The cylinder body of the first lifting cylinder 202 is fixed to the top of the gantry 201, and the guide rod of the first lifting cylinder 202 is connected to the clamping plate 205, which is used to drive the clamping plate 205 to do lifting and lowering movement. During this period, the first guide column 204 will be driven to rise and fall synchronously in the first guide sleeve 203, and the stability of the lifting and lowering movement of the clamping plate 205 is ensured by relying on the guiding function of the first guide column 204 and the first guide sleeve 203.

[0053] The finger cylinder 206 is fixed to the bottom of the clamping plate 205, and the clamping block 209 is installed on the finger cylinder 206. The finger cylinder 206 drives the two groups of clamping blocks 209 to move inward or outward synchronously. Fig.10 The figure shows the structure of the clamp block 209. The top of the clamp block 209 is fixed on the finger cylinder 206. The inner side of the bottom of the clamp block 209 is provided with a slot 210 for fixing and installing a clamp plate 212. The boss 211 is integrally connected to the inner side of the slot 210 and matches with the groove 214 of the clamp plate 212.

[0054] like Fig.11 As shown, it is a schematic diagram of the structure of the clamping plate 212. The outer side of the clamping plate 212 is provided with a groove 214 that matches the boss 211. When the clamping plate 212 is actually installed, the clamping plate 212 is clamped in the clamping groove 210. At this time, the boss 211 and the groove 214 are matched and clamped, and then the clamping block 209 and the clamping plate 212 are fixed by screws. When the finger cylinder 206 drives the clamping block 209 to move, it will drive the clamping plate 212 to move synchronously, thereby completing the work of taking and placing the positioning column 215. By setting the clamping groove 210, the boss 211 and the groove 214, the clamping plate 212 on the clamping block 209 can be limited to avoid the position of the clamping plate 212 from being offset, thereby affecting the insertion of the positioning column 215.

[0055] The clamping groove 213 is formed on the inner side of the clamping plate 212 and is arc-shaped for clamping the positioning column 215. The arc-shaped clamping groove 213 is used to match the outer peripheral surface of the positioning column 215 to prevent the positioning column 215 from falling when the positioning column 215 is clamped.

[0056] The initial positioning plate 207 is fixed to the bottom of the clamping plate 205 through a fixing plate and is arranged horizontally. The initial positioning hole 208 vertically penetrates the initial positioning plate 207. When clamping the positioning column 215, the initial positioning plate 207 and the initial positioning hole 208 are arranged to perform preliminary positioning on the positioning column 215, thereby improving the accuracy of the position when the clamping plate 212 clamps the positioning column 215.

[0057] like Fig.12 , which is a schematic diagram of the structure of the positioning column 215. The positioning column 215 is used to assist in assembling the vehicle end protection pad 43 to prevent the flexible vehicle end protection pad 43 from being improperly assembled during assembly. A guide portion 216 is provided at the top of the positioning column 215 to facilitate the vehicle end protection pad 43 to be sleeved on the positioning column 215 and to facilitate the positioning column 215 to be inserted into the sleeve hole 309. An avoidance hole 217 is provided at the top of the positioning column 215 to avoid the pressure head 312 of the press-fit assembly 3.

[0058] like Fig.13 , which is a schematic diagram of the structure of the press-fitting assembly 3, which is fixedly mounted on the gantry 201 and located on one side of the clamping assembly 2. The press-fitting assembly 3 is used to absorb the vehicle end protection pad 43 and press-fit the vehicle end protection pad 43 on the vehicle end connection body 42. The press-fitting assembly 3 includes a second lifting cylinder 301, a second guide sleeve 302, a second guide column 303, a primary pressing plate 304, a secondary pressing plate 305, a secondary positioning hole 306, a suction plate 307, a sleeve 308, a sleeve hole 309, a pressing rod 310, a pressing plate 311, a pressing head 312 and a pushing cylinder 313.

[0059] The second guide sleeve 302 is embedded in the top of the gantry 201, the second guide column 303 passes through the second guide sleeve 302, and the bottom of the second guide column 303 is fixed with the initial pressing plate 304. The cylinder body of the second lifting cylinder 301 is fixed on the top of the gantry 201, and the guide rod of the second lifting cylinder 301 is connected to the initial pressing plate 304, which is used to drive the initial pressing plate 304 to do lifting and lowering movement. During this period, the second guide column 303 will be driven to rise and fall synchronously in the second guide sleeve 302, and the stability of the lifting and lowering movement of the initial pressing plate 304 is ensured by relying on the guiding function of the second guide column 303 and the second guide sleeve 302.

[0060] The sleeve 308 is fixed to the bottom of the primary pressing plate 304, and the sleeve hole 309 is provided in the sleeve 308. The diameter of the sleeve hole 309 is equal to the outer diameter of the positioning column 215. When the second lifting cylinder 301 drives the sleeve 308 to descend, the positioning column 215 on the vehicle end connection body 42 is smoothly inserted into the sleeve hole 309 under the guidance of the guide part 216. Since the diameter of the sleeve hole 309 is equal to the outer diameter of the positioning column 215, the positioning column 215 on the vehicle end connection body 42 will not shake under the action of the sleeve hole 309. At this time, when the secondary pressing plate 305 pushes the vehicle end protection pad 43 to move downward, the vehicle end protection pad 43 is sleeved on the positioning column 215 and moves downward smoothly, thereby improving the accuracy of the position of the vehicle end protection pad 43 when it is installed.

[0061] The pressure rod 310 is fixed to the top of the inner side of the sleeve 308, the pressure plate 311 is integrally connected to the bottom of the pressure rod 310, the pressure head 312 is integrally connected to the bottom of the pressure plate 311, and the diameter of the pressure head 312 is smaller than the diameter of the avoidance hole 217, and the diameter of the pressure plate 311 is larger than the diameter of the avoidance hole 217. When the second lifting cylinder 301 drives the sleeve 308 to descend, under the guidance of the guide part 216, the positioning column 215 on the vehicle end connection body 42 is smoothly inserted into the sleeve hole 309. When the top of the positioning column 215 abuts against the lower surface of the pressure plate 311, the second lifting cylinder 301 stops moving, and the pressure head 312 is inserted into the avoidance hole 217 of the positioning column 215. By setting the pressure plate 311, the position of the descending sleeve 308 is limited. At the same time, through the cooperation of the pressure head 312 and the avoidance hole 217, the top of the positioning column 215 can be limited again. When the vehicle-end protection pad 43 is pressed and installed, the shaking of the positioning column 215 is avoided, thereby affecting the installation effect of the vehicle-end protection pad 43.

[0062] The secondary pressing plate 305 is connected to the lower part of the primary pressing plate 304 through the pushing cylinder 313. The suction plate 307 is fixed to the bottom of the secondary pressing plate 305 and is used to suck the vehicle end protection pad 43 in the vehicle end protection pad groove 112. The vehicle end protection pad 43 on the suction plate 307 is pushed downward by the pushing cylinder 313. The secondary positioning hole 306 vertically penetrates the secondary pressing plate 305. When the second lifting cylinder 301 drives the sleeve 308 to descend, it avoids the positioning column 215 below, ensuring that the positioning column 215 is smoothly inserted into the sleeve hole 309.

[0063] The working principle of the press-fitting assembly 3 is as follows: the second lifting cylinder 301 drives the suction plate 307 to descend, and the suction plate 307 first sucks the vehicle end protection pad 43 in the vehicle end protection pad groove 112, and then the second lifting cylinder 301 is reset; the feeding assembly 1 moves the vehicle end bracket 4 carrying the positioning column 215 to the bottom of the press-fitting assembly 3, and the second lifting cylinder 301 drives the primary pressing plate 304 to descend, and the positioning column 215 is placed in the sleeve hole 309 through the secondary pressing plate 305. Since the diameter of the sleeve hole 309 is equal to the outer diameter of the positioning column 215, the positioning column 215 is positioned by the sleeve 308;

[0064] When the top of the positioning column 215 abuts against the lower surface of the pressing plate 311, the second lifting cylinder 301 stops moving. At this time, the pressing head 312 is inserted into the avoidance hole 217 of the positioning column 215. Through the cooperation between the pressing head 312 and the avoidance hole 217, the top of the positioning column 215 can be limited again. When the vehicle end protection pad 43 is pressed and installed, the shaking of the positioning column 215 is avoided, thereby affecting the installation effect of the vehicle end protection pad 43.

[0065] At the same time, during the descent process of the suction plate 307, the vehicle end protection pad 43 on the suction plate 307 will be driven to move downward synchronously, and the pad hole 44 of the vehicle end protection pad 43 passes through the positioning column 215 and gradually moves downward. Since the diameter of the pad hole 44 is smaller than the outer diameter of the positioning column 215, the vehicle end protection pad 43 will undergo elastic deformation and expand. Under the effect of the deformation of the vehicle end protection pad 43, the vehicle end protection pad 43 is prevented from rotating, thereby causing the assembly to be incomplete. When the pressure plate 311 is against the top of the positioning column 215, the vehicle end protection pad 43 on the suction plate 307 is pushed downward by pushing the cylinder 313, and the descending vehicle end protection pad 43 finally breaks away from the positioning column 215 and is sleeved on the vehicle end connection body 42 of the vehicle end bracket 4.

[0066] The pressing principle of the press-fitting structure of the utility model is as follows:

[0067] First, the feeding component 1 delivers the vehicle-end protection pad 43 and the vehicle-end bracket 4 to the bottom of the clamping component 2, and the clamping component 2 inserts the positioning column 215 on the vehicle-end connecting body 42 of the vehicle-end bracket 4, and the suction plate 307 of the press-fitting component 3 sucks the vehicle-end protection pad 43 in the vehicle-end protection pad groove 112; then the feeding component 1 delivers the vehicle-end bracket 4 carrying the positioning column 215 to the bottom of the press-fitting component 3, and under the action of the press-fitting component 3, the vehicle-end protection pad 43 is mounted on the vehicle-end connecting body 42 through the positioning column 215.

[0068] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
