[0039] The present application will be further described below in conjunction with the accompanying drawings and examples.

Figures 1 to 9

[0042] ​The pressing mechanism comprises hollow vertical columns 51, two hollow vertical columns 51 are installed on the bottom frame 1 and are communicated with the bottom frame 1, a cross beam 52 is fixedly installed between the ends of the two hollow vertical columns 51 away from the bottom frame 1, a hydraulic machine 53 is installed on the middle part of the cross beam 52 through bolts, a hollow sliding plate 54 is installed on the hydraulic machine 53, a pressing block 55 is slidingly arranged on the hollow sliding plate 54, and an opening is formed in the top of the bottom frame 1 and is below the pressing block 55.

[0043] The placing mechanism comprises horizontal shafts 61, two horizontal shafts 61 are rotatably arranged on the two sides of the sliding frame 4 away from the two guide rods 3, a placing frame 62 for placing the radiator body 41 is fixedly installed between the two horizontal shafts 61 through bolts, a fixed plate 63 is fixedly installed on one side in the placing frame 62, two sliding plates 64 are slidingly arranged on the side of the placing frame 62 opposite to the fixed plate 63, two fastening bolts 65 are rotatably arranged on the side of the placing frame 62 close to the two sliding plates 64 through bearings, the two fastening bolts 65 are threadedly connected with the two sliding plates 64 respectively, two limiting grooves 67 are formed in the outer side of the side of the placing frame 62 close to the fixed plate 63, and two limiting bolts 66 are threadedly connected with the side of the sliding frame 4 close to the limiting grooves 67.

[0044] The placing frame 62 and the fixed plate 63 form a limiting clamping groove.

[0045] The collecting mechanism comprises lower fixed plates 71, a lower fixed plate 71 is fixedly installed on the bottom of the placing frame 62, and eighteen pressure sensors 72 are uniformly and interval arranged on the side of the lower fixed plate 71 close to the radiator body 41.

[0046] In actual use, the use principle of the tension test equipment for the automobile radiator can be that when the radiator body 41 is tested, the lid 2 is opened first, then one end of the radiator body 41 to be tested is clamped into the clamping groove formed between the placing frame 62 and the fixed plate 63, after the radiator body 41 is placed flat, the operator rotates the two fastening bolts 65, the two fastening bolts 65 drive the two sliding plates 64 to move towards the fixed plate 63, the radiator body 41 is fixed through the placing frame 62, the fixed plate 63 and the two sliding plates 64, then the operator closes the lid 2, and at the beginning, the ends of the two limiting bolts 66 are located in the limiting grooves 67, therefore, the placing frame 62 and the radiator body 41 will not swing.

[0047] Subsequently, the operator controls the extension rod of the hydraulic press 53 to extend. The hydraulic press 53 drives the hollow slide plate 54 and the lower pressure block 55 to approach the radiator body 41 through the extension rod. After the lower pressure block 55 passes through the opening of the bottom frame 1 and contacts one side of the radiator body 41, it begins to apply a certain pressure, thereby pushing the radiator body 41 to deform. During this process, the pressure sensor 72 monitors the deformation of the radiator body 41 in real time. As the lower pressure block 55 applies pressure, the radiator body 41 gradually deforms. The pressure sensor 72 closely captures the pressure changes at every moment and transmits the data to the data acquisition system. This real-time transmitted data is then further processed by professional analysis instruments. The processed data can be used to determine the maximum tensile force that the radiator body 41 can withstand, that is, its load-bearing capacity under specific working conditions.

[0048] After the radiator body 41 has been tested, the operator controls the extension rod of the hydraulic press 53 to shorten. The extension rod of the hydraulic press 53 drives the hollow slide plate 54 and the lower pressure block 55 to move away from the radiator body 41 and reset. Then the operator opens the cover 2 and rotates the two fastening bolts 65 in the opposite direction. The two fastening bolts 65 drive the two sliding plates 64 to move away from the fixed plate 63. After the two sliding plates 64 separate from the radiator body 41, the operator can take out the tested radiator body 41.

[0049] Example 2

[0050] The tensile testing equipment for the car radiator in this embodiment is based on that in Embodiment 1, such as... Figures 9 to 14 As shown, it also includes a pushing mechanism, which is set on the bottom frame 1, the sliding frame 4 and the hollow slide plate 54. The pushing mechanism is used to push the radiator body 41 to move. The pushing mechanism includes a vertical shaft 81. A vertical shaft 81 is rotatably provided in the middle of the bottom of the bottom frame 1 through a bearing. A turntable 82 is fixedly installed on the upper part of the vertical shaft 81. A vertical roller 83 is rotatably provided on the side of the turntable 82 near the sliding frame 4 through a bearing. A slotted plate 84 is fixedly installed on the side of the sliding frame 4 near the turntable 82. A slot is opened on the slotted plate 84. The vertical roller 83 is located in the slot on the slotted plate 84.

[0051] A supersonic clutch 85 is installed at the lower part of the vertical shaft 81. A spur gear 86 is installed on the supersonic clutch 85. A sliding frame 87 is slidably installed at the bottom of the bottom frame 1. The sliding frame 87 will slide along the bottom frame 1. A spur rack 88 is fixedly installed on the sliding frame 87. After the spur rack 88 moves, it will mesh with the spur gear 86. Two slotted plates 89 are fixedly installed on the sliding frame 87. The two slotted plates 89 are symmetrically arranged. A vertical plate 810 is fixedly installed on both sides of the hollow slide plate 54. The two vertical plates 810 are located in the two hollow vertical columns 51 respectively. A flat roller 811 is rotatably installed on the lower side of the two vertical plates 810 that is far apart from each other.

[0052] Each of the two slotted plates 89 has a drive groove on one side that is close to each other. The drive groove on the slotted plate 89 consists of an inclined groove and a vertical groove. The two flat rollers 811 are located in the inclined grooves of the drive grooves on the two slotted plates 89 respectively.

[0053] In practical use, the operating principle of the tensile testing device for the automotive radiator of the present invention can be as follows: When the hollow slide plate 54 and the lower pressure block 55 move toward the direction close to the radiator body 41, they drive the two vertical plates 810 and the two flat rollers 811 to move. When the two flat rollers 811 move from the inclined groove of the drive groove on the two slotted plates 89 to the vertical groove of the drive groove on the slotted plates 89, the two flat rollers 811 will drive the two slotted plates 89 to move toward the direction close to the cover 2. The two slotted plates 89 drive the sliding frame 87 and the flat rack 88 to move toward the direction close to the cover 2. After the flat rack 88 meshes with the flat gear 86, the flat rack 88 drives the flat gear 86 to rotate. Under the action of the overrunning clutch 85, the flat gear 86 drives the overrunning clutch 85, the vertical shaft 81, the turntable 82 and the vertical roller 83 to rotate.

[0054] When the hollow slide plate 54 and the lower pressure block 55 move away from the radiator body 41, they drive the two vertical plates 810 and the two flat rollers 811 to move. When the two flat rollers 811 move from the straight groove of the drive groove on the two slotted plates 89 to the inclined groove of the drive groove on the slotted plates 89, the two flat rollers 811 will drive the two slotted plates 89 to move away from the cover 2. The two slotted plates 89 will drive the sliding frame 87 and the flat rack 88 to move away from the cover 2. The flat rack 88 will drive the flat gear 86 to rotate in the opposite direction. Under the action of the overrunning clutch 85, the flat gear 86 will not drive the vertical shaft 81, the turntable 82 and the vertical roller 83 to rotate.

[0055] The hollow slide plate 54 drives the two vertical plates 810 and the two horizontal rollers 811 to move up and down reciprocally. The two horizontal rollers 811 move within the drive slots of the two slotted plates 89, thereby driving the sliding frame 87 and the rack and pinion 88 to move continuously back and forth. The continuous movement of the rack and pinion 88 drives the gear 86 to rotate back and forth. Under the action of the overrunning clutch 85, the gear 86 intermittently transmits power, driving the vertical shaft 81, the turntable 82 and the vertical roller 83 to rotate in the same direction. The rotation of the vertical roller 83 further causes the slotted plate 84 to reciprocate intermittently. The movement of the slotted plate 84 drives the sliding frame 4, the horizontal shaft 61, the placement frame 62, the fixing plate 63, the sliding plate 64 and other components to move. Next, the fastening bolt 65, radiator body 41, limit bolt 66, lower plate 71, and pressure sensor 72 will also stop after intermittently reciprocating on the two guide rods 3. This process simulates the different contact and force points that the radiator body 41 may encounter in actual use. In particular, when the contact position between the lower pressure block 55 and the radiator body 41 is constantly changing, due to the variability of the contact position, it can simulate the diverse positions and force distributions when the radiator body 41 is impacted. This allows for a comprehensive simulation and testing of the working state of the radiator body 41 in actual use, providing strong data support for its design improvement and quality control, and ensuring the reliability and safety of the product.

[0056] When the pressing block 55 contacts the heat sink body 41, the two flat rollers 811 are located in the straight grooves of the drive slots on the two slotted plates 89. Therefore, when the pressing block 55 contacts the heat sink body 41, the heat sink body 41 will not be displaced. Furthermore, the position of the heat sink body 41 can be fixed by the limiting of the two flat rollers 811 and the straight grooves of the drive slots on the two slotted plates 89.

[0057] Example 3

[0058] The tensile testing equipment for the car radiator in this embodiment is based on that in Embodiment 2, such as... Figures 9 to 17 As shown, it also includes a swing mechanism, which is set on the bottom frame 1, the slide frame 4, the horizontal shaft 61 and the turntable 82. The swing mechanism is used to drive the radiator body 41 to swing. The swing mechanism includes a swing gear 91. A swing gear 91 is fixedly installed on each of the two horizontal shafts 61. Two horizontal racks 92 are slidably provided on the slide frame 4. The horizontal racks 92 will slide along the slide frame 4. Several tooth blocks are evenly spaced in the middle of the two horizontal racks 92. The tooth blocks on the two horizontal racks 92 mesh with the two swing gears 91 respectively.

[0059] Two translation frames 93 are slidingly arranged in the bottom frame 1, two ends of the two horizontal racks 92 are slidingly connected with the two translation frames 93 respectively, the lower parts of the two translation frames 93 are rotatably provided with a translation roller 94, the rotating disc 82 is fixedly provided with a corrugated groove disc 95, the corrugated groove disc 95 is provided with a corrugated groove on the side close to the translation roller 94, and the two translation rollers 94 are located in the corrugated groove of the corrugated groove disc 95.

[0060] The tension test equipment for the automobile radiator in the embodiment further comprises a moving mechanism arranged on the hollow vertical column 51, the hollow sliding plate 54 and the pressing block 55, the moving mechanism is used for adjusting the position of the pressing block 55, the hollow sliding plate 54 is rotatably provided with a bidirectional screw rod 101, the pressing block 55 is fixedly provided with a bidirectional screw nut 102, the bidirectional screw nut 102 is threadedly connected with the bidirectional screw rod 101, the two ends of the bidirectional screw rod 101 are arranged to pass through the two sides of the hollow sliding plate 54, the two ends of the bidirectional screw rod 101 are provided with an overrunning clutch 103, the two overrunning clutches 103 are provided with a vertical gear 104, one side of the two hollow vertical columns 51 is fixedly provided with a vertical rack 105, and the vertical gear 104 in the same hollow vertical column 51 is meshed with the vertical rack 105 in the same hollow vertical column 51.

[0061] In actual use, the use principle of the tension test equipment for the automobile radiator can be that the operator rotates the two limiting bolts 66, the two limiting bolts 66 move away from the two limiting grooves 67, the two limiting bolts 66 are separated from the two limiting grooves 67, the sliding frame 4 drives the two horizontal racks 92 to slide on the two translation frames 93, the rotating disc 82 drives the corrugated groove disc 95 to intermittently rotate and stop, the corrugated groove on the corrugated groove disc 95 drives the two translation rollers 94 to synchronously reciprocate and stop, the two translation rollers 94 drive the two translation frames 93 to synchronously reciprocate and stop, the two translation frames 93 drive the two horizontal racks 92 to synchronously reciprocate and stop, the teeth on the two horizontal racks 92 drive the swing gears 91 to reciprocate and stop, and the rotation of the two swing gears 91 transmits kinetic energy to the two horizontal shafts 61, so that the horizontal shafts 61 reciprocate and stop within a certain range.

[0062] Through the reciprocating rotation of the horizontal shafts 61, the placement frame 62, the fixed plate 63, the sliding plate 64, the fastening bolt 65 and the radiator body 41 also start to reciprocate, until the movement of the placement frame 62, the fixed plate 63, the sliding plate 64, the fastening bolt 65 and the radiator body 41 is stopped, and the relative angle of the radiator body 41 and the pressing block 55 when they are in contact can be effectively changed.

[0063] Due to the interaction of the horizontal rack 92, the swing gear 91 and the horizontal shaft 61, the radiator body 41 is in different angles and force positions when it contacts the pressing block 55 each time. Specifically, the contact angle of the radiator body 41 changes constantly along the movement track, simulating the force situation of the radiator body 41 in different directions and angles. This change can simulate the various contact situations that the radiator body 41 may experience in actual working process.

[0064] When the hollow slide plate 54 and the pressing block 55 move towards the radiator body 41, the hollow slide plate 54 and the pressing block 55 drive the bidirectional screw rod 101, the bidirectional nut 102, the overrunning clutch two 103 and the vertical gear 104 to move. Under the action of the two vertical racks 105, the two vertical gears 104 rotate synchronously. Under the action of the two overrunning clutches two 103, the two vertical gears 104 drive the bidirectional screw rod 101 to rotate together. Then the two vertical gears 104 are separated from the two vertical racks 105. When the two vertical gears 104 are separated from the two vertical racks 105, the two flat rollers 811 are located in the straight grooves of the driving grooves on the two slotted plates 89.

[0065] When the hollow slide plate 54 and the pressing block 55 move away from the radiator body 41, the hollow slide plate 54 and the pressing block 55 drive the bidirectional screw rod 101, the bidirectional nut 102, the overrunning clutch two 103 and the vertical gear 104 to move. When the two vertical gears 104 engage with the two vertical racks 105, the two vertical gears 104 rotate reversely synchronously. Under the action of the two overrunning clutches two 103, the two vertical gears 104 do not drive the bidirectional screw rod 101 to rotate.

[0066] Through the reciprocating movement of the hollow slide plate 54 and the pressing block 55, the bidirectional screw rod 101, the bidirectional nut 102, the overrunning clutch two 103 and the vertical gear 104, through the engagement of the vertical gear 104 and the vertical rack 105, under the action of the overrunning clutch two 103, the bidirectional screw rod 101 can be driven to rotate intermittently in one direction and then stop. The bidirectional nut 102 can move intermittently on the bidirectional screw rod 101 for a distance and then stop. The bidirectional nut 102 drives the pressing block 55 to move intermittently on the hollow slide plate 54 for a distance and then stop. In this way, the position of the pressing block 55 in contact with the radiator body 41 in another direction can be changed. The diversified force situation of the radiator body 41 when it is impacted in different directions can be simulated. The force situation of the radiator body 41 in different directions and positions can be tested. By adjusting the position of the contact between the pressing block 55 and the radiator body 41, the force situation of the radiator body 41 under impact in multiple directions can be simulated. The change in position and direction makes the test cover more actual use scenarios, so as to obtain comprehensive multi-dimensional detection data.

[0067] Finally, it should be noted that the above examples are merely intended to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present application.
