Description

Technical Field

[0001] This utility model relates to the field of automotive roof cutting technology, specifically a high-pressure water cutting device for automotive roof production. Background Technology

[0002] Waterjet cutting, also known as water jet cutting, involves using a high-pressure water jet to form a water column and then carving the surface of a workpiece under computer control. Due to its low cost and ease of operation, it is widely used in industrial cutting technology.

[0003] The main material of the car roof panel is polyurethane. After the panel is made, water jet cutting is used to carve it in order to avoid deformation caused by high-temperature cutting. However, water jet cutting of the panel poses certain safety hazards. Since the finished panel is an irregularly shaped structure, the panel is subjected to great pressure from the water jet cutting. If the water jet is repeatedly started and stopped, the frequent start-up of the water cutting device will increase energy consumption. On the other hand, if the water cutting device is continuously run, it is difficult to accurately control the surface of the panel to be cut.

[0004] In view of this, a high-pressure water jet cutting device for automobile roof production was designed to solve the above problems. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a high-pressure water cutting device for automobile roof production.

[0021] Example 1: Combination Figures 1 to 5As shown, the present invention provides a high-pressure water jet cutting device for automobile roof production, including an automobile roof panel 300, a panel groove alignment mechanism 200 for clamping the automobile roof panel 300, a cutting distance adjustment mechanism 100 disposed on the panel groove alignment mechanism 200, and a water jet cutter 400 disposed directly above the automobile roof panel 300. The cutting distance adjustment mechanism 100 is fixed on the workbench and is used to provide a support platform for adjusting the cutting distance of the panel groove alignment mechanism 200. The panel groove alignment mechanism 200 is used to clamp the automobile roof panel 300 and provide a precise cutting path for the water jet sprayed by the water jet cutter 400.

[0022] The plate groove alignment mechanism 200 includes two beam plates 210, two support plates 220, and two shielding plates 230. A second bidirectional screw 2202 is installed inside the beam plate 210. The bottom end of the second bidirectional screw 2202 is movably installed in the support plate 220. Two symmetrically distributed second guard plates 2103 are inserted into the bottom of the beam plate 210. A first guard plate 2102 is inserted into the inner side of the two second guard plates 2103. Two symmetrically distributed third guard plates 2104, two fourth guard plates 2105, and two fifth guard plates 2106 are inserted into both ends of the bottom of the beam plate 210. A first positioning plate 2301, a second positioning plate 2302, and a third positioning plate 2303 are fixedly installed at the bottom of the shielding plate 230, and the bottom ends of the first positioning plate 2301, the second positioning plate 2302, and the third positioning plate 2303 are fixedly installed on the top of the beam plate 210. The third protective plate 2104, the fourth protective plate 2105 and the fifth protective plate 2106 have a U-shaped structure; Two second bolts 2101 are fixedly installed at the bottom of the beam 210, and the top base 130 is installed outside the two second bolts 2101; A cantilever 2201 is movably installed between the beam 210 and the support plate 220, and the second bidirectional screw 2202 is located at the center of the inner side of the cantilever 2201. The pallet 220 has an overall L-shaped structure, and the upper surface of the pallet 220 has a groove that fits the bottom of the car roof panel 300.

[0023] The two second double-direction screws 2202 are pre-rotated until the two support plates 220 and the two beam plates 210 are expanded to their maximum state. Then, the car roof panel 300 is laterally inserted into the gap between the beam plate 210 and the support plate 220 until the car roof panel 300 is supported on the inner side of the two support plates 220. Then, the two second double-direction screws 2202 are rotated again until the two support plates 220 move closer to the two beam plates 210 until the car roof panel 300 is quickly locked and fixed. The two first guard plates 2102 and the four second guard plates 2103 can provide quick calibration clamping for the side of the largest convex surface inside the car roof panel 300, while the third guard plate 2104, the fourth guard plate 2105 and the fifth guard plate 2106 can calibrate and clamp the side of the smaller convex surface inside the car roof panel 300. Meanwhile, the baffle plate 230, which is fixed to the top of the beam plate 210 by the first matching plate 2301, the second matching plate 2302, and the third matching plate 2303, provides a precise cutting path for the water jet sprayed by the water cutter 400. As the water jet sprayed by the water cutter 400 cuts downward along the inner grooves of the two baffle plates 230, the water jet will precisely cut along the convex surface of the inner side of the car roof panel 300. After the convex side is protected by pressure, the lateral pressure generated by the water jet will be protected by the first protective plate 2102, the second protective plate 2103, the third protective plate 2104, the fourth protective plate 2105, and the fifth protective plate 2106, so as to avoid the convex side from deforming due to excessive lateral pressure of the water jet.

[0024] Example 2: Combination Figure 3 and Figure 4 As shown, based on Embodiment 1, the tangent adjustment mechanism 100 includes two bases 110, a truss 160 is fixedly installed on the inner side of the two bases 110, a drawer plate 1601 is movably installed inside the truss 160, and a horizontally placed first bidirectional lead screw 170 is threaded inside the truss 160. Two first bolts 1101 are fixedly installed on the top of the base 110. A bottom base 120 is installed on the outside of the two bases 110. A bottom arm 1401 is movably installed inside the bottom base 120. A shaft 1402 is movably installed at the other end of the bottom arm 1401. A top arm 140 is movably installed on the outside of the shaft 1402. A top base 130 is movably installed at the other end of the top arm 140.

[0025] Preferably, the base 110 has three evenly distributed elliptical slots inside, and the top arm 140 and the top base 130 are both welded together from L-shaped pads and guide rods. The top arm 140 and the bottom arm 1401 are both made of aluminum alloy.

[0026] The bottom lever arm 1401 is externally mounted with a pad 1403, and the inner end of the first bidirectional lead screw 170 is movably mounted inside the pad 1403. Both the bottom arm 1401 and the top arm 140 have internal sliding tracks, and both tracks have movable carriages 150. A limiting rod 1501 is fixedly installed inside the base 110, and the limiting rod 1501 is adapted to pass through the two slides 150. Two reinforcing springs 1502 are provided on the outside of the limiting rod 1501, and the two reinforcing springs 1502 are respectively connected to the two slides 150.

[0027] Preferably, the top end of the limiting rod 1501 is adapted to penetrate into the interior of the beam plate 210, the two top reinforcing springs 1502 are pressed against the bottom of the beam plate 210, the two bottom reinforcing springs 1502 are pressed against the two bases 110, and the slide 150 is welded together from two rectangular end plates and insert rods, while the ends of the reinforcing springs 1502 that are away from the beam plate 210 or away from the bases 110 are fixedly installed on the rectangular end plates.

[0028] The working principle and usage process of this utility model are as follows: The assembled truss 160 and two bases 110 are fixedly installed on the workbench in advance using expansion bolts until the beam plate 210 and the support plate 220 extend beyond the workbench from the section away from the tangent adjustment mechanism 100. Then, the two second bidirectional lead screws 2202 are reversed. As the two second bidirectional lead screws 2202 continue to descend, the two symmetrically distributed support plates 220 will be compressed and descend to the maximum state. Next, insert the two support plates 220, which have expanded to their maximum angle, into the car roof panel 300 until the bottom of the car roof panel 300 rests in the grooves on the upper surfaces of the two support plates 220. Then, forward drive the two second double-acting lead screws 2202 until they return to their original position and rise. Finally, the pressure on the two support plates 220 will cause the car roof panel 300 to rise and be pressed tightly by the lower surfaces of the two beam plates 210. The two symmetrically distributed first guard plates 210... 2. The four second guard plates 2103 will adapt and clamp the largest convex surface of the car roof panel 300, while the fourth guard plate 2105, the fifth guard plate 2106 and the two third guard plates 2104 will adapt and clamp the smaller convex surface of the car roof panel 300. The shielding plate 230 fixedly installed on the top of the beam plate 210 by the first matching plate 2301, the second matching plate 2302 and the third matching plate 2303 will expose the inner convex surface of the car roof panel 300. As the water jet cutter 400 is driven by the external drive device and moves at a constant speed directly above the two baffles 230, the high-pressure water jet sprayed from the water jet cutter 400 will precisely cut the convex surface of the inner side of the car roof panel 300 along the grooves on the inner side of the two baffles 230. With the parts of the car roof panel 300 other than the inner convex surface protected, the water jet sprayed by the water jet cutter 400 can be prevented from damaging other parts of the car roof panel 300.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
