Description

Technical Field

[0001] This invention belongs to the technical field of explosion-proof aluminum shell processing, and specifically relates to a positioning device for explosion-proof aluminum shell processing. Background Technology

[0002] Aluminum housings, made of aluminum alloy, are used to house instruments, tools, and measuring instruments. They typically include an outer shell, panel, lining, and support, primarily serving to protect the internal components. The main body of the housing is made of high-quality aluminum alloy profiles, featuring a rational design, robust structure, and aesthetically pleasing appearance. They are widely used in industries such as instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, and precision machinery, making them ideal housings for high-end instruments. Surface treatment involves electrostatic spraying, with colors including off-white, dark gray, black, and military green.

[0003] As disclosed in CN110369942B, a welding fixture for a square aluminum-cased battery cover includes a full-welding positioning unit. The full-welding positioning unit includes a first bottom support plate and a first clamping assembly for clamping the side of the battery. A positioning pressure plate is provided above the full-welding turntable unit. The full-welding positioning unit or the positioning pressure plate is connected to a translation drive mechanism. A support plate base is provided below the first bottom support plate. The support plate base is connected to a first lifting drive component. A top column and elastic elements located on both sides of the top column are clamped between the support plate base and the first bottom support plate. The bottom end of the top column is fixedly connected to the support plate base, and the top surface of the top column presses against the first bottom support plate. In this welding fixture for a square aluminum-cased battery cover, the first clamping assembly forms a channel for lifting and lowering the battery. The positioning pressure plate presses down on the battery cover. The elastic elements between the first bottom support plate and the support plate base self-adjust, ensuring the horizontality of the battery cover and helping to improve the welding quality of the cover.

[0004] However, problems still exist: although the device can complete the clamping and positioning of the aluminum shell, and the elastic element between the first bottom support plate and the support plate base can adaptively adjust to ensure the levelness of the battery cover, the aluminum shell cannot be adjusted and straightened during the clamping and positioning process. The operator needs to manually straighten it, which reduces the positioning effect and processing efficiency. Summary of the Invention

The first threaded hole convex slider and the second threaded hole convex slider are threadedly connected to the front and rear outer walls of the double-threaded rod. Both the first threaded hole convex slider and the second threaded hole convex slider slide inside the second slide groove. At the same time, the protruding ends of the first threaded hole convex slider and the second threaded hole convex slider both extend through and out of the third slide groove.

[0013] Compared with the prior art, the present invention provides a positioning device for processing explosion-proof aluminum shells, which has the following beneficial effects:

[0014] 1. This invention, through a driving mechanism, can drive two clamping and positioning mechanisms to move simultaneously toward the center or simultaneously toward the outside. When the two clamping and positioning mechanisms move simultaneously toward the center, the two driving components can drive four toggle positioning components to move synchronously toward the center or synchronously toward the outside. When the clamping wheels of the L-shaped connecting frame in the four toggle positioning components contact the four corners of the explosion-proof aluminum shell, the rotation of the L-shaped connecting frame and the extension and contraction of the spring enable the L-shaped connecting frame and the clamping wheels to perform toggle correction work on the explosion-proof aluminum shell, thereby enabling the explosion-proof aluminum shell to complete the alignment work, and also enabling the four toggle positioning components to perform clamping and positioning work on the explosion-proof aluminum shell, improving the positioning effect and processing efficiency.

[0015] 2. During the simultaneous movement of the two clamping and positioning mechanisms toward the center, the invention can clamp and position the explosion-proof aluminum shell through the double-groove arc-shaped elastic plate and clamping roller of the elastic clamping component. At the same time, the rotation of the clamping roller on the outer wall of the explosion-proof aluminum shell facilitates the four toggle positioning components to toggle and correct the explosion-proof aluminum shell, so that the explosion-proof aluminum shell can be centered and the positioning effect is improved.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please see Figure 1-12 The present invention provides a technical solution: a positioning device for processing explosion-proof aluminum shells, including a fixed base 2, a U-shaped placement platform 4, a driving mechanism and a clamping and positioning mechanism. The upper middle part of the fixed base 2 is welded with a U-shaped placement platform 4 for component installation and placement of explosion-proof aluminum shells. Two symmetrical clamping and positioning mechanisms are slidably sleeved on the upper side of the U-shaped placement platform 4. The interior of the U-shaped placement platform 4 is provided with a driving mechanism for driving the clamping and positioning mechanisms.

[0032] Through the drive mechanism, two clamping and positioning mechanisms can be driven to move simultaneously toward the center or simultaneously toward the outside. When the two clamping and positioning mechanisms move simultaneously toward the center, the two drive components can drive four toggle positioning components to move synchronously toward the center or synchronously toward the outside. When the clamping wheel 17 of the L-shaped connecting frame 13 in the four toggle positioning components contacts the four corners of the explosion-proof aluminum shell, the L-shaped connecting frame 13 rotates and the spring 25 extends and retracts, so that the L-shaped connecting frame 13 and the clamping wheel 17 can perform toggle correction work on the explosion-proof aluminum shell, thereby enabling the explosion-proof aluminum shell to complete the alignment work, and also enabling the four toggle positioning components to perform clamping and positioning work on the explosion-proof aluminum shell.

[0033] During the simultaneous movement of the two clamping and positioning mechanisms toward the center, the explosion-proof aluminum shell can be clamped and positioned by the double-groove arc-shaped elastic plate 1 and the clamping roller 14 of the elastic clamping assembly. At the same time, the rotation of the clamping roller 14 on the outer wall of the explosion-proof aluminum shell facilitates the four toggle positioning components to toggle and correct the explosion-proof aluminum shell, so that the explosion-proof aluminum shell can be centered and the positioning effect is improved.

[0034] like Figures 3-12 As shown, the clamping and positioning mechanism includes a sliding sleeve 3, a drive assembly, a toggle positioning assembly, and an elastic clamping assembly, such as... Figure 11 and Figure 12 As shown, the sliding sleeve 3 also includes a third sliding groove 29, a first sliding groove 30, and a second sliding groove 31. The first sliding groove 30 is located in the middle of the sliding sleeve 3, and the second sliding groove 31 is located on the upper side of the sliding sleeve 3, communicating with the first sliding groove 30. Sleeve holes 32 are formed on the inner walls of the front and rear sides of the second sliding groove 31. The third sliding groove 29 is located at the end of the sliding sleeve 3 near the elastic clamping assembly, and the third sliding groove 29 communicates with the second sliding groove 31. The sliding sleeve 3 facilitates the installation of the drive assembly, the toggle positioning assembly, and the elastic clamping assembly. The drive assembly is rotatably connected inside the sliding sleeve 3, such as... Figure 3 and Figure 4As shown, the drive assembly includes a double-threaded rod 19, a roller 20, a first threaded hole convex slider 18, and a second threaded hole convex slider 21. The double-threaded rod 19 is located inside the first slide groove 30, and both ends of the double-threaded rod 19 are rotatably connected to two sleeve holes 32. The roller 20 is sleeved on the outer wall of the middle part of the double-threaded rod 19, and the edge of the roller 20 contacts the upper surface of the U-shaped placement platform 4. The first threaded hole convex slider 18 and the second threaded hole convex slider 21 are threadedly connected to the outer walls of the front and rear sides of the double-threaded rod 19, and both the first threaded hole convex slider 18 and the second threaded hole convex slider 21 slide inside the second slide groove 31. Simultaneously, the protruding ends of the first screw-hole convex slider 18 and the second screw-hole convex slider 21 both extend through the third slide groove 29. The direction of the threaded hole of the first screw-hole convex slider 18 is opposite to the direction of the threaded hole of the second screw-hole convex slider 21, so that the double threaded rod 19 drives the first screw-hole convex slider 18 and the second screw-hole convex slider 21 to move synchronously towards the center or synchronously towards the outside, thereby driving the toggle positioning component to complete the clamping and positioning work. The sliding sleeve 3 is provided with two symmetrical toggle positioning components, and the drive component drives the two toggle positioning components to complete the clamping and positioning work, such as Figure 5 , Figure 6 and Figure 7 As shown, the toggle positioning assembly includes a hollow protective shell 5, a connecting shaft 24, an L-shaped connecting frame 13, and a clamping wheel 17. The connecting shaft 24 is rotatably connected to the inside of the hollow protective shell 5 near the sliding sleeve post 3, with both ends of the connecting shaft 24 extending through the upper and lower end faces of the hollow protective shell 5. Convex circular plates 27 are rotatably connected to the upper and lower outer walls of the connecting shaft 24, and two convex circular plates 27 are symmetrically welded to the upper and lower ends of the hollow protective shell 5. A second limiting cylinder 22 is provided on the protruding side of the two convex circular plates 27. L-shaped connecting frames 13 are welded to the upper and lower ends of the connecting shaft 24, and the two L-shaped connecting frames 13 are located on the upper and lower sides of the hollow protective shell 5. A second cylinder 26 is welded to the surface of the two L-shaped connecting frames 13 near the convex circular plates 27, and the second cylinder 26 is away from the second limiting cylinder. The column 22, the two L-shaped connecting frames 13 are rotatably connected to the two sides of the clamping wheels 17, the upper and lower ends of the hollow protective shell 5 are welded with the first limiting cylinder 15 near the sliding sleeve column 3, and the first limiting cylinder 15, the center of the convex circular plate 27, and the second limiting cylinder 22 are on the same straight line. The upper and lower ends of the hollow protective shell 5 are welded with the first cylinder 23 away from the sliding sleeve column 3. A spring 25 is provided between the two first cylinders 23 and the two second cylinders 26. Through the spring 25, the two L-shaped connecting frames 13 and the four clamping wheels 17 can easily complete the turning and clamping work of the explosion-proof aluminum shell. At the same time, it can also facilitate the two L-shaped connecting frames 13 and the four clamping wheels 17 to complete the reset work. The sliding sleeve column 3 is provided with an elastic clamping component, and the elastic clamping component is located between the two turning and positioning components. Figure 8 and Figure 9 As shown, the elastic clamping assembly includes a double-groove arc-shaped elastic plate 1, a clamping roller 14, and a U-shaped connecting seat 28. The U-shaped connecting seat 28 is welded to the middle of the interior of the third slide groove 29. The double-groove arc-shaped elastic plate 1 is welded to the protruding end of the U-shaped connecting seat 28. The clamping roller 14 is rotatably connected to both sides of the double-groove arc-shaped elastic plate 1. The double-groove arc-shaped elastic plate 1 is elastic. The double-groove arc-shaped elastic plate 1 has opening grooves on both sides that match the clamping roller 14. The clamping roller 14 is rotatably sleeved inside the opening grooves. Through the elastic clamping assembly, the explosion-proof aluminum shell can be clamped and positioned.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive mechanism includes a servo motor 7, a round rod 8, a swing rod 9, a connecting lug 10, and an annular sleeve 16. The annular sleeve 16 is rotatably connected to the upper and lower outer walls of the round rod 8, and the two annular sleeves 16 are symmetrically welded to the center of the upper and lower inner walls of the U-shaped placement platform 4. A first gear 11 is sleeved on the lower outer wall of the round rod 8, and a swing rod 9 is sleeved on the upper outer wall of the round rod 8. Connecting rods 6 are rotatably connected to both sides of the swing rod 9, and connecting lugs 10 are rotatably connected to the other side of the two connecting rods 6. The connecting lugs 10 are welded to the outer wall of the sliding sleeve 3. The servo motor 7 is installed at the bottom of the U-shaped placement platform 4 and is located behind the round rod 8. A second gear 12 is sleeved on the outer wall of the motor shaft of the servo motor 7, and the second gear 12 meshes with the first gear 11. Through the drive mechanism, the clamping and positioning mechanism can be driven to complete the clamping and positioning work.

[0036] The working principle and usage process of this invention: Before use, the operator first installs and fixes the fixed base 2 on the turntable of the processing equipment with bolts. Then, the operator can electrically connect the servo motor 7 to the controller of the processing equipment through wires.

[0037] In use, the operator first places the aluminum shell to be processed on the upper surface of the U-shaped placement table 4. Then, by operating the controller of the processing equipment, the operator causes the servo motor 7 to work in the forward direction, thereby driving the second gear 12 to rotate in the forward direction. Since the second gear 12 meshes with the first gear 11, the second gear 12 will drive the first gear 11 to rotate in the forward direction, which in turn drives the round rod 8 and the swing rod 9 to rotate in the forward direction. When the swing rod 9 rotates in the forward direction, it will pull the two sliding sleeves 3 through the two connecting rods 6 and the two connecting lugs 10. The roller 20 slides on the outer wall of the U-shaped placement platform 4 towards the aluminum shell to be processed. At the same time, since the wheel edge of the roller 20 is in contact with the upper surface of the U-shaped placement platform 4, the two sliding sleeves 3 will drive the two rollers 20 to rotate in the forward direction during the sliding process, which will drive the two double threaded rods 19 to rotate in the forward direction. When the two double threaded rods 19 rotate in the forward direction, they will drive the two first screw hole convex sliders 18 and the two second screw hole convex sliders 21 to move synchronously towards the center, which will cause the four toggle positioning components to move synchronously towards the center.

[0038] As the two sliding sleeves 3 slide toward the aluminum shell to be processed, the two elastic clamping components move toward the aluminum shell to be processed. When the two clamping rollers 14 in the two elastic clamping components come into contact with the explosion-proof aluminum, the two double-groove arc-shaped elastic plates 1 deform. At this time, through the elastic force of the two deformed double-groove arc-shaped elastic plates 1 and the four clamping rollers 14, the aluminum shell to be processed can be clamped and positioned, and the aluminum shell to be processed will gradually move toward the center.

[0039] As the four actuating positioning components move synchronously towards the center, the clamping wheels 17 on the outer side of the L-shaped connecting frame 13 in the four actuating positioning components will slowly approach the four corners of the aluminum shell to be processed. When the clamping wheels 17 on the outer side of the L-shaped connecting frame 13 in the four actuating positioning components contact the four corners of the aluminum shell to be processed, the L-shaped connecting frame 13 will rotate, thereby enabling the clamping wheels 17 on the outer side of the L-shaped connecting frame 13 in the four actuating positioning components to actuate and correct the aluminum shell to be processed. The clamping wheels 17 will also move on the outer wall of the aluminum shell. At the same time, during the actuation and correction process, the two double-groove arc-shaped elastic plates 1 in the two elastic clamping components will continue to deform, and the four clamping rollers 14 will also roll on the outer wall of the aluminum shell to be processed. At this time, the two deformed double-groove arc-shaped elastic plates 1, the four clamping rollers 14, and the eight rotating L-shaped connecting frames will again move the aluminum shell to be processed. The frame 13 and eight clamping wheels 17 allow the aluminum shell to be processed to gradually complete the centering and alignment work. In addition, as the eight L-shaped connecting frames 13 rotate, the clamping wheels 17 on the other side of the eight L-shaped connecting frames 13 slowly approach the outer wall of the aluminum shell to be processed. When the clamping wheels 17 on the other side of the L-shaped connecting frames 13 contact the outer wall of the aluminum shell to be processed, the force of the spring 25, as well as the two L-shaped connecting frames 13 and the four clamping wheels 17 in the four toggle positioning components, will clamp and fix the four corners of the aluminum shell to be processed. Thus, through the two deformed double-groove arc-shaped elastic plates 1, the four clamping rollers 14, the rotating eight L-shaped connecting frames 13 and the sixteen clamping wheels 17, the centering and clamping positioning of the aluminum shell to be processed can be completed, thereby facilitating the processing equipment to process the aluminum shell to be processed.
