Description

TECHNICAL FIELD

[0001] The application relates to the technical field of welding equipment, in particular to x-axis reinforcing rib welding positioning equipment with self-adaptive clamps. BACKGROUND

[0002] An aging cabinet, also known as a burn-in cabinet, is a key device for pre-burning test of semi-finished products or finished products in the electronic communication industry, which accelerates the screening of early failure components through simulation of a high-temperature environment and improves product reliability. The aging cabinet is usually internally provided with multiple layers of plates for placing multiple groups of devices to be tested for experiments. In order to improve the support strength of the plates, reinforcing ribs running along the x-axis are usually welded to the bottom of the plates.

[0003] When the x-axis reinforcing rib is welded, the x-axis reinforcing rib needs to be accurately placed on the layer plate at the position to be welded. The existing welding equipment usually adopts a welding positioning clamp to position the layer plate and the x-axis reinforcing rib. When positioning, the layer plate is placed between the fixed clamps, then the x-axis reinforcing rib is placed on the layer plate, the position of the x-axis reinforcing rib is roughly positioned by visual observation, then the x-axis reinforcing rib is fixed by using the clamp, and then the x-axis reinforcing rib and the layer plate are welded. The above-mentioned welding equipment has the following disadvantages in actual use: the above-mentioned welding positioning clamp can only position the layer plate and the x-axis reinforcing rib of a specific size after being installed. When positioning the layer plate and the x-axis reinforcing rib of different sizes, different positioning clamps need to be replaced, and the positioning function is limited and needs to be further improved. SUMMARY

[0005] The clamping unit one comprises a concave frame slidably installed on the rectangular frame, a clamping plate one is fixedly connected to one side of the concave frame close to the center of the base, a push plate is slidably installed between the two vertical sections of the concave frame, a spring one is fixedly connected between the push plate and the clamping plate one and is sleeved outside the vertical sections of the concave frame, a driving assembly is installed on the base and drives the push plate to move towards the center of the base, and a limiting assembly is also installed on the rectangular frame and limits the movement of the concave frame away from the center of the base.

[0006] The second clamping unit includes a mounting base that is slidably mounted on the first clamping plate and symmetrically distributed front and back. A clamping arm is hinged to the mounting base. An adaptive component is mounted on one end of the clamping arm near the center of the base. A clamping component for driving the two clamping arms to move towards each other to perform clamping is also mounted on the first clamping plate.

[0007] In one possible implementation, the drive assembly includes a turntable rotatably mounted inside a base, the turntable having a plurality of circumferentially evenly distributed arc-shaped grooves, a pull rod slidably mounted inside the base, the end of the pull rod away from the center of the base being fixedly connected to the bottom of a push plate, a slider being rotatably connected to the end of the pull rod near the turntable, the slider being slidably mounted in a corresponding arc-shaped groove, a drive motor for driving the turntable to rotate being fixedly mounted at the bottom of the base, and the top of the turntable output shaft being coaxially fixedly connected to the bottom of the turntable.

[0008] In one possible implementation, the limiting assembly includes a housing fixedly connected to the side of the rectangular frame away from the center of the base. A central gear is rotatably mounted in the middle of the housing. Racks mesh on both sides of the central gear. A pawl is fixedly connected to one end of the rack extending outside the housing. Wedge-shaped grooves are provided on opposite sides of the two vertical sections of the concave frame. The tooth surfaces of the pawls cooperate with the corresponding wedge-shaped grooves to form a unidirectional transmission effect. A spring is fixedly connected between the side of the pawl near the central gear and another adjacent rack.

[0009] In one possible implementation, the central gear is internally threaded with a threaded rod, the top end of which slides through to the top of the housing. The threaded rod is slidably connected to the housing vertically, and the tops of several threaded rods are jointly fixedly connected to a pressure frame.

[0010] In one possible implementation, the adaptive component includes guide rods that are slidably mounted on one end of the clamping arm near the center of the base and are symmetrically distributed on the left and right. The two guide rods are fixedly connected to a clamping plate two on the side near the center of clamping plate one. A spring three sleeved on the outside of the guide rods is fixedly connected between clamping plate two and the clamping arm. A plurality of ball bearings distributed in a matrix are rotatably mounted on the side of clamping plate two near the center of clamping plate one.

[0011] In one possible implementation, the clamping assembly includes a movable block that is slidably mounted on the side of the clamping plate away from the center of the base and is symmetrically distributed front and back. The movable block is fixedly mounted on the bottom of the corresponding mounting base. A T-shaped piece is fixedly connected to the side of the push plate near the center of the base. A second slider that is symmetrically distributed front and back is rotatably mounted on the top of the horizontal section of the T-shaped piece. The movable block has a first inclined groove. The two first inclined grooves are V-shaped with the larger opening facing the center of the base. The second slider is slidably mounted inside the corresponding first inclined groove.

[0012] In one possible implementation, the clamping unit includes a support frame fixedly connected to a side of the clamping plate away from the center of the base and located between two front and rear clamping arms. A pressure rod is hinged to the support frame, and a rotating assembly for driving the pressure rod and the clamping arms to rotate synchronously in opposite directions is mounted on the support frame.

[0013] In one possible implementation, the rotating assembly includes a drive gear rotatably mounted on a support frame and located at the bottom of a pressure rod. The end of the pressure rod near the corresponding support frame is provided with teeth and meshes with the drive gear. A transmission rod is coaxially fixedly connected to the side of the clamping arm near the corresponding drive gear. The transmission rod and the drive gear are connected by a spline connection. A second drive motor for driving the clamping arm to rotate is fixedly mounted on the front mounting base. The output shaft of the second drive motor is coaxially fixedly connected to the clamping arm.

[0014] The beneficial effects of the present invention are as follows: 1. When welding the layer plates, the push plate pushes the clamping plate to center and clamp the layer plates through the spring, which can quickly position the layer plates. The spring can adaptively extend and retract according to the size of the layer plates, which is convenient for clamping and fixing layer plates of different sizes. After the clamping plate clamps the layer plates, the limiting component is used to limit the concave frame to prevent the concave frame and the clamping plate from moving away from the center of the base during welding, thus preventing the layer plates from moving during welding and ensuring the firmness of the clamping plate when it is fixed.

[0015] 2. In this invention, while the pusher plate pushes the clamping plate to perform centering and clamping positioning of a pair of layers, the pusher plate pushes the clamping arms closer together through the clamping assembly to perform front and rear centering and clamping positioning of the x-axis reinforcing rib. The adaptive assembly can adaptively extend and retract according to the size of the x-axis reinforcing rib, which is convenient for clamping and positioning x-axis reinforcing ribs of different sizes. After the centering and clamping of the x-axis reinforcing rib is completed, the rotating assembly drives the clamping arms and the pressure rod to rotate synchronously in opposite directions, so that the pressure rod flips down and presses against the x-axis reinforcing rib, while the clamping arms flip up and leave the x-axis reinforcing rib. While fixing the x-axis reinforcing rib, it can avoid the clamping arms and the adaptive assembly located on the front and rear sides of the x-axis reinforcing rib from affecting the movement and welding of the laser welding mechanism.

Detailed Implementation

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Please see Figure 1 - Figure 8An X-axis reinforcing rib welding and positioning device with adaptive clamps includes a base 1 and a laser welding mechanism 2 installed above the base 1. It also includes a clamping mechanism 3, which includes a rectangular frame 31 fixedly installed on the top of the base 1. Clamping units 32 for positioning the layer are installed on all four sides of the rectangular frame 31. Clamping units 33 and pressing units 34 for positioning the X-axis reinforcing ribs are installed on the left and right clamping units 32.

[0027] The clamping unit 32 includes a concave frame 321 slidably mounted on a rectangular frame 31. A clamping plate 322 is fixedly connected to the side of the concave frame 321 near the center of the base 1. A push plate 323 is slidably mounted between the two vertical sections of the concave frame 321. A spring 324 sleeved on the outside of the vertical section of the concave frame 321 is fixedly connected between the push plate 323 and the clamping plate 322. A drive assembly 325 is mounted on the base 1 to drive the push plate 323 to move towards the center of the base 1. A limiting assembly 326 is also mounted on the rectangular frame 31 to limit the movement of the concave frame 321 away from the center of the base 1. A stop block 3211 located between the push plate 323 and the rectangular frame 31 is also fixedly connected to the top of the vertical section of the concave frame 321. When the side of the push plate 323 away from the center of the base 1 abuts against the stop block 3211, the spring 324 returns to its original length.

[0028] The clamping unit 2 33 includes a mounting base 331 that is slidably mounted on the clamping plate 1 322 and symmetrically distributed front and back. A clamping arm 332 is hinged on the mounting base 331. An adaptive component 333 is mounted on one end of the clamping arm 332 near the center of the base 1. A clamping component 334 for driving the two clamping arms 332 to move towards each other to perform clamping is also mounted on the clamping plate 1 322.

[0029] In actual use, in the initial state, the clamping arm 332 is in a vertical position, and the stop block 3211 abuts against the inner wall of the rectangular frame 31. First, the shelf is placed between the four clamping plates 322, and then the x-axis reinforcing rib is placed at the top of the shelf near the middle. The drive assembly 325 drives the four push plates 323 to move synchronously towards the center of the base 1. The push plates 323 push the clamping plates 322 towards the center of the base 1 through the spring 324, so that the clamping plates 322 are clamped around the shelf. The spring 324 can produce different degrees of expansion and contraction deformation according to different sizes of shelf, which is convenient for adaptive adjustment according to different sizes of shelf.

[0030] When clamping plate 322 moves toward the center of base 1, it will drive concave frame 321 to move together. At this time, the limiting component 326 will limit concave frame 321 to prevent it from moving away from the center of base 1, thus preventing clamping plate 322 from loosening after clamping the shelf and improving the stability of the shelf fixation. When clamping plate 322 moves, it will drive clamping arm 332 to move together. When clamping plate 322 clamps the shelf around the perimeter, clamping arm 332 rotates to a horizontal state. At this time, adaptive component 333 is located on the front and rear sides of x-axis reinforcing rib.

[0031] When clamping plate 322 is held around the shelf, push plate 323 continues to move towards the center of base 1. At this time, the distance between push plate 323 and clamping plate 322 is shortened. Push plate 323 drives the two corresponding clamping arms 332 to move closer to each other through clamping assembly 334. The clamping arms 332 drive the adaptive assembly 333 to clamp the x-axis reinforcing rib in a front-to-back centering manner. This can position the x-axis reinforcing rib to the center of the top of the shelf, ensuring the accuracy of the positioning of the x-axis reinforcing rib and the shelf. This facilitates the subsequent welding of the x-axis reinforcing rib and the shelf. The adaptive assembly 333 can expand and contract to different degrees according to the different widths of the x-axis reinforcing rib, which is convenient for adaptive adjustment according to the different widths of the x-axis reinforcing rib.

[0032] After welding is completed, the limiting component 326 is released from the concave frame 321. Then, the push plate 323 is driven to move away from the center of the base 1 by the drive component 325. In the initial stage, the spring 324 is in a compressed state. The rebound force of the spring 324 will push the clamping plate 322 to keep clamping the shelf. As the push plate 323 moves, the distance between the push plate 323 and the clamping plate 322 increases. The push plate 323 drives the two corresponding clamping arms 332 to move away from each other through the clamping component 334. When the two corresponding clamping arms 332 are moved away to the maximum state, the push plate 323 moves to the state of contact with the stop block 3211.

[0033] Then, the clamping arm 332 is rotated to a vertical position, and the push plate 323 is driven by the drive component 325 to continue moving away from the center of the base 1. The push plate 323 will drive the concave frame 321 and the clamping plate 322 to move away from the center of the base 1, so that the clamping plate 322 releases its grip on the layer plate. Finally, the welded layer plate is removed from the base 1.

[0034] Please see Figure 2 , Figure 3 and Figure 4The drive assembly 325 includes a turntable 3251 rotatably mounted inside the base 1. The turntable 3251 has several circumferentially evenly distributed arc-shaped grooves 3252. A pull rod 3253 is slidably mounted inside the base 1. The end of the pull rod 3253 away from the center of the base 1 is fixedly connected to the bottom of the push plate 323. A slider 3254 is rotatably connected to the end of the pull rod 3253 near the turntable 3251. The slider 3254 is slidably mounted in the corresponding arc-shaped groove 3252. A drive motor 3255 for driving the turntable 3251 to rotate is fixedly mounted at the bottom of the base 1. The top of the output shaft of the turntable 3251 is coaxially fixedly connected to the bottom of the turntable 3251.

[0035] Please see Figure 2 , Figure 3 and Figure 5 The limiting component 326 includes a housing 3261 fixedly connected to the side of the rectangular frame 31 away from the center of the base 1. A central gear 3262 is rotatably mounted in the middle of the housing 3261. Racks 3263 mesh on both the left and right sides of the central gear 3262. A pawl 3264 is fixedly connected to one end of the rack 3263 extending to the outside of the housing 3261. Wedge grooves 3212 are provided on the opposite sides of the two vertical sections of the concave frame 321. The tooth surface of the pawl 3264 cooperates with the corresponding wedge groove 3212 to form a one-way transmission effect. A spring 3265 is fixedly connected between the side of the pawl 3264 near the central gear 3262 and the adjacent rack 3263.

[0036] In practical use, when the concave frame 321 moves towards the center of the base 1, the inclined surface of the claw 3264 slides against the inclined surface of the wedge groove 3212. The wedge groove 3212 pushes the claw 3264 towards the housing 3261. At this time, the second spring 3265 is compressed and does not restrict the movement of the concave frame 321. When the concave frame 321 moves away from the center of the base 1, the wedge groove 3212 will engage with the claw 3264 to prevent the concave frame 321 from moving away from the center of the base 1 and to prevent the clamping plate 322 from loosening when holding it.

[0037] Please see Figure 2 , Figure 3 and Figure 5 The central gear 3262 is internally threaded with a threaded rod 3266. The top end of the threaded rod 3266 slides through to the top of the housing 3261. The threaded rod 3266 and the housing 3261 are slidably connected vertically. The tops of several threaded rods 3266 are fixedly connected to a lower pressure frame 3267.

[0038] In practical use, when it is necessary to release the restriction on the concave frame 321, the pressure frame 3267 is pushed to move downward. The pressure frame 3267 pushes several threaded rods 3266 to move downward simultaneously. The threaded rods 3266 drive the central gear 3262 to rotate counterclockwise. The central gear 3262 drives the racks 3263 and pawls 3264 on the left and right sides to move away from the corresponding wedge grooves 3212, thereby releasing the restriction of the pawls 3264 on the wedge grooves 3212.

[0039] Please see Figure 3 , Figure 6 and Figure 7 The adaptive component 333 includes guide rods 3331 that are slidably mounted on one end of the clamping arm 332 near the center of the base 1 and are symmetrically distributed on the left and right. The two guide rods 3331 are fixedly connected to a clamping plate 3332 on the side near the center of the clamping plate 322. A spring 3333 is fixedly connected between the clamping plate 3332 and the clamping arm 332 and is sleeved on the outside of the guide rods 3331. A number of balls distributed in a matrix are rotatably mounted on the side of the clamping plate 3332 near the center of the clamping plate 322.

[0040] In practical use, when the front and rear clamping arms 332 approach each other to clamp the x-axis reinforcing rib, the second clamping plate 3332 first contacts the front and rear side walls of the x-axis reinforcing rib. The second clamping plates 3332 on both sides are used to center and clamp the x-axis reinforcing rib, which facilitates the positioning of the x-axis reinforcing rib and the shelf. When the second clamping plate 3332 is clamped on the front and rear sides of the x-axis reinforcing rib, the third spring 3333 will be compressed and contracted. The third spring 3333 can contract to different degrees according to the width of the x-axis reinforcing rib, and can adaptively adjust according to the different widths of the x-axis reinforcing rib, thus improving the applicability. By setting ball bearings in the second clamping plate 3332, the friction between the second clamping plate 3332 and the x-axis reinforcing rib can be reduced, making it easier for the second clamping plate 3332 to slide away from the x-axis reinforcing rib.

[0041] Please see Figure 6 and Figure 7 The clamping assembly 334 includes a movable block 3341 that is slidably mounted on the side of the clamping plate 322 away from the center of the base 1 and is symmetrically distributed front and back. The movable block 3341 is fixedly mounted on the bottom of the corresponding mounting base 331. A T-shaped piece 3342 is fixedly connected to the side of the push plate 323 near the center of the base 1. A slider 3343 symmetrically distributed front and back is rotatably mounted on the top of the horizontal section of the T-shaped piece 3342. The movable block 3341 is provided with a first inclined groove 3344. The two first inclined grooves 3344 are V-shaped and the larger opening faces the center of the base 1. The slider 3343 is slidably mounted inside the corresponding first inclined groove 3344.

[0042] In practical use, when the push plate 323 approaches the clamping plate 322, the push plate 323 pushes the T-shaped piece 3342 to gradually approach the clamping plate 322. The slider 3343 slides along the inclined groove 3344. The slider 3343 pushes the two corresponding movable blocks 3341 to move closer to each other, so that the movable blocks 3341 drive the two corresponding clamping arms 332 to move closer to each other to perform centering and clamping of the x-axis reinforcing rib.

[0043] When the push plate 323 moves away from the clamping plate 322, the push plate 323 drives the T-shaped piece 3342 to gradually move away from the clamping plate 322. The slider 3343 drives the two corresponding movable blocks 3341 to move away from each other, so that the movable blocks 3341 drive the two corresponding clamping arms 332 to move away from each other and release the clamping of the x-axis reinforcing rib.

[0044] Please see Figure 2 , Figure 6 and Figure 8 The clamping unit 34 includes a support frame 341 fixedly connected to the side of the clamping plate 322 away from the center of the base 1 and located between the front and rear clamping arms 332. A pressure rod 342 is hinged on the support frame 341. A rotating assembly 343 for driving the pressure rod 342 and the clamping arms 332 to rotate synchronously in opposite directions is installed on the support frame 341.

[0045] Please see Figure 6 and Figure 8 The rotating assembly 343 includes a drive gear 3431 rotatably mounted on the support frame 341 and located at the bottom of the pressure rod 342. The end of the pressure rod 342 near the corresponding support frame 341 is provided with teeth and meshes with the drive gear 3431. The clamping arm 332 is coaxially fixedly connected to the side near the corresponding drive gear 3431 with a transmission rod 3432. The transmission rod 3432 and the drive gear 3431 are connected by a spline connection. A second drive motor 3433 for driving the clamping arm 332 to rotate is fixedly mounted on the front mounting base 331. The output shaft of the second drive motor 3433 is coaxially fixedly connected to the clamping arm 332.

[0046] In practical use, after the clamping arm 332 completes the centering and clamping of the x-axis reinforcing rib, the drive motor 3433 drives the clamping arm 332 to rotate counterclockwise, so that the clamping arm 332 rotates from a horizontal state to a vertical state. When the clamping arm 332 rotates, it will drive the transmission rod 3432 to rotate together. The transmission rod 3432 drives the drive gear 3431 to rotate. The drive gear 3431 drives the pressure rod 342 to rotate in the opposite direction, so that the pressure rod 342 can rotate from a vertical state to a horizontal state, so that the pressure rod 342 presses against the top of the x-axis reinforcing rib, improving the stability of the x-axis reinforcing rib and preventing the x-axis reinforcing rib from moving during the welding process. Conversely, when the clamping arm 332 rotates from a vertical state to a horizontal state, the pressure rod 342 can rotate from a horizontal state to a vertical state.

[0047] By using a spline connection to connect the drive gear 3431 and the transmission rod 3432, when the movable block 3341 drives the mounting base 331 to move back and forth, the transmission rod 3432 can slide with the drive gear 3431, thus meeting the transmission needs of the clamping arm 332 and the drive gear 3431 at different distances.
