Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of quality inspection experiments for aluminum parts, and specifically to a quality inspection device for aluminum parts. Background Art
[0002] Impact resistance is the ability of a specimen to resist the action of impact loads. Common impact resistance test methods include the simply supported beam impact test, the cantilever beam impact test, and the drop hammer test. The drop hammer test is closer to the actual situation than the pendulum impact test and is a simple and practical method. In the drop weight test, a heavy hammer falls from different heights onto the specimen to obtain the relationship between the falling height and the failure rate of the specimen, and the impact resistance of the product is measured by measuring the impact deformation marks on the specimen. However, for the existing testing machines used in the drop hammer test, when conducting the impact test on aluminum products, when the test hammer falls from a high place onto the aluminum product to be tested, since the aluminum product is a hard material, the heavy hammer is prone to rebound after falling, causing the heavy hammer to move up a certain distance and then fall again, impacting the aluminum product again, causing the aluminum product to bear a secondary impact, deepening the test marks on the aluminum product, and thus affecting the test results. Some existing drop hammer testing machines are equipped with sensors and cylinders. When the rebound of the drop hammer is detected, the drop hammer is lifted by the cylinder to avoid secondary impact. However, due to the strong impact vibration generated during the operation of the drop hammer testing machine, using sensors and cylinders to lift the drop hammer has low reliability.

[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. Through the setting of the clamping module, the mounting seat falls freely, and the impact block impacts the aluminum part. When the impact block and the mounting seat collide with the aluminum part and rebound, the counterweight module moves downward under the action of inertia, so that the counterweight module pushes the limit rod to move to both sides through the push rod, so that the limit rod squeezes the spring rod, thereby disengaging the limit rod from the clamping of the spring rod, and the two clamping seats move away from each other to the sides, and the clamping seats are clamped with the clamping groove part, so that the mounting seat rebounds. During the secondary impact process, the clamping seat is clamped with the support rod, thereby avoiding the secondary impact of the mounting seat on the aluminum part, avoiding damage to the imprint produced by the first impact, and facilitating the subsequent analysis of the impact imprint. The setting of the clamping module effectively limits the secondary impact of the impact block, with low cost and high reliability.
[0021] 2. Through the setting of the outer support rod group, when the mounting seat is released, the lifting mechanism is reset, and then the driving module drives the three support rods to retract toward the middle, so that the outer seat is out of contact with the support rods, and the mounting seat is in a completely empty state. Then the mounting seat falls, avoiding connection with other parts and thus delaying the fall of the mounting seat, making it convenient to determine the downward impact force of the mounting seat by the mass and height of the mounting seat.

Detailed implementation manners
[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] Please refer to Figures 1 to 5, in the embodiment of the present invention, an aluminum part quality inspection device includes a vertical frame mechanism 100, a lifting mechanism 200, a mounting seat 300, and a fixture 400. The fixture 400 is used to clamp and fix the aluminum part. The vertical frame mechanism 100 includes a top plate 120 and two bases 110. An outer support rod group 130 is arranged between the base 110 and the top plate 120. A driving module 140 is installed at the top end of the top plate 120. The driving module 140 is used to drive the outer support rod group 130. A support rod 150 is fixedly connected between the base 110 and the top plate 120. The support rod 150 is located on one side of the outer support rod group 130. The mounting seat 300 is movably sleeved between the two outer support rod groups 130. An impact block 330 is fixedly connected to the bottom end of the mounting seat 300. A clamping module 340 is fixedly connected to the top end of the mounting seat 300. The clamping module 340 is used to be clamped with the support rods 150 on both sides. The lifting mechanism 200 is installed on the top plate 120. The lifting mechanism 200 is used to drive the mounting seat 300 to move upward;
[0035] The clamping module 340 includes a weight module 341. Two movable seats 343 are fixedly connected to both ends of the top surface of the mounting seat 300. A limiting rod 344 is slidably connected to the top end of the movable seat 343. A clamping seat 345 is fixedly connected between one ends of two adjacent limiting rods 344. The clamping seat 345 is clamped with the adjacent support rod 150. The other end of the limiting rod 344 is rotatably connected to a push rod 342. One ends of a plurality of push rods 342 are rotatably connected to the weight module 341. A notch 347 is formed in the middle position of the outer side wall of the limiting rod 344. A spring rod 346 is arranged inside the bottom end of the movable seat 343. The spring rod 346 is clamped with the notch 347 on the adjacent limiting rod 344. The top ends of the notch 347 and the spring rod 346 are wedge-shaped. A clamping groove portion 151 is arranged at the bottom end of the outer side wall of the support rod 150. One outer side wall of the clamping seat 345 fits with the clamping groove portion 151.
[0036] Specifically, the aluminum part is clamped and fixed on the fixture 400, such that the aluminum part is located below the mounting base 300. After the lifting mechanism 200 drives the mounting base 300 to rise to a predetermined height, the driving module 140 drives the outer support rod group 130 to support the mounting base 300. After the lifting mechanism 200 is reset, the outer support rod group 130 releases the mounting base 300, and the mounting base 300 freely falls to impact the aluminum part through the impact block 330. When the impact block 330 and the mounting base 300 rebound after hitting the aluminum part, the counterweight module 341 moves downward under the action of inertia, such that the counterweight module 341 pushes the limit rod 344 to move to both sides through the push rod 342, such that the limit rod 344 squeezes the spring rod 346, thereby causing the limit rod 344 to disengage from the clamping of the spring rod 346. The two clamping seats 345 move away from each other to both sides, and the clamping seats 345 are clamped with the slot part 151, so that during the secondary impact of the rebound of the mounting base 300, the mounting base 300 is stuck by the clamping seats 345 and the support rod 150, thereby avoiding the secondary impact of the mounting base 300 on the aluminum part and preventing the damage to the imprint generated by the first impact, facilitating the subsequent analysis of the impact imprint.
[0037] Embodiment 1
[0038] Such as Figures 1 to 7As shown, in this embodiment, both ends of the mounting seat 300 are fixedly connected with an outer sleeve seat 310, and a triangular prism hole 311 is provided in the middle position of the outer sleeve seat 310. The outer sleeve seat 310 is used to be sleeved on the outer support rod group 130 on the adjacent side. Both ends of the top surface of the mounting seat 300 are provided with a vent hole 320, and the vent hole 320 is used to avoid the support rod 150. The outer support rod group 130 includes two sliding seats 133, one of which is fixed on the base 110, and the other is fixed to the top plate 120. A support rod 131 is slidably connected between the two sliding seats 133, and a center rod 132 is rotatably connected between the two sliding seats 133. A plurality of bidirectional threaded sleeves 134 are equidistantly fixed to the outer wall of the center rod 132, and both ends of the outer wall of the bidirectional threaded sleeve 134 are screwed together with an internal threaded sleeve 135. The two internal threaded sleeves 135 The three corresponding support rods 131 are rotatably connected with V-shaped connecting rods 136, and one end of the V-shaped connecting rod 136 is rotatably connected to the inner wall of the corresponding support rod 131. The top of the center rod 132 is transmission-connected to the drive module 140, and the top of the top plate 120 is rotatably connected to the transmission rod 141. The top of the center rod 132 is fixedly sleeved with a bevel gear 142, and the outer wall of the transmission rod 141 corresponding to the position of the bevel gear 142 is fixedly sleeved with a bevel gear 2 143, and the bevel gear 2 143 is meshed with the adjacent bevel gear 142. A drive motor 144 is fixedly installed at one end of the top plate 120, and the output end of the drive motor 144 is self-tightly connected to the transmission rod 141. One end of the transmission rod 141 is fixedly connected with a worm gear 146, and the output end of the drive motor 144 is fixedly sleeved with a worm 145, which meshes with the worm gear 146.
[0039] When the mounting base 300 is moved up to a predetermined height, the driving motor 144 drives the transmission rod 141 to rotate through the worm 145 and the worm gear 146. The transmission rod 141 drives the center rod 132 to rotate through the bevel gear 2 143 and the bevel gear 142. When the center rod 132 rotates, it drives the two-way threaded sleeve 134 to rotate. The rotation of the two-way threaded sleeve 134 drives the two internal threaded sleeves 135 to move closer to each other, so that the V-shaped connecting rod 136 pushes the three support rods 131 to slide away from each other, thereby squeezing the triangular prism hole 311 through the three support rods 131 to support the mounting base 300. When the mounting base 300 is released, the lifting mechanism 200 is reset, and then the driving module 140 drives the three support rods 131 to retract toward the middle, so that the outer sleeve 310 is out of contact with the support rod 131, and the mounting base 300 is in a completely empty state. Then the mounting base 300 falls, avoiding connection with other parts, thereby delaying the fall of the mounting base 300.
[0040] Example 2
[0041] like Figures 5 to 10As shown in the figure, in this embodiment, the lifting mechanism 200 includes a second transmission rod 250. The second transmission rod 250 is rotatably connected to the top plate 120. A sliding rod 220 is fixedly connected between the base 110 and the top plate 120. The sliding rod 220 is located between the support rod 150 and the outer support rod group 130 on the same side. A lifting seat 210 is slidably sleeved on the outer side wall of the sliding rod 220. The lifting seat 210 is located below the mounting seat 300. The lifting seat 210 is slidably connected to the adjacent support rod 150. A pulling rope 230 is fixedly connected to the middle position of the lifting seat 210. A guiding wheel 240 is rotatably connected to the top end of the top plate 120 corresponding to the upper positions of the two lifting seats 210. Winding wheels 251 are fixedly sleeved at both ends of the outer side wall of the second transmission rod 250. The top end of the pulling rope 230 bypasses the adjacent guiding wheel 240 and is wound around the winding wheel 251. A winch 260 is fixedly installed at the other end of the top plate 120. The output end of the winch 260 is drivingly connected to the second transmission rod 250. Support seats 410 are fixedly connected to both ends of the top side of the fixture 400. A pressing rod 420 is screwed to the top end of the support seat 410.
[0042] During specific implementation, after the impact is completed, the clamping seat 345 and the support rod 150 are in a clamped state. Manually push the clamping seat 345 to make the notch 347 and the spring rod 346 re-clamp, so that the counterweight module 341 is reset. The clamping seat 345 and the support rod 150 are in a completely separated state. The winch 260 drives the second transmission rod 250 to rotate. The second transmission rod 250 winds the pulling rope 230 through the winding wheel 251, thereby pulling the lifting seat 210 upward. When the lifting seat 210 moves upward, it lifts the mounting seat 300 to a predetermined height. After the mounting seat 300 moves to the predetermined height, the outer support rod group 130 supports the mounting seat 300. Subsequently, the winch 260 drives the second transmission rod 250 to reverse, so that the lifting seat 210 slides down to the lowest position to prevent the mounting seat 300 from being received by the lifting seat 210 when it drops.
