Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an adjustable-angle friction welding device. Background Technology

[0002] Friction stir welding is a novel welding method that utilizes a special stirring head inserted into the joint of the workpiece. The stirring head rotates at high speed as it moves forward, generating a large amount of heat that puts the metal at the welding point into a thermoplastic state and forms a whole under the pressure of the stirring head. During friction stir welding, a small amount of debris exists on the surface of the workpiece. Due to the high surface temperature of the workpiece immediately after welding, it is inconvenient to effectively clean the debris. Utility Model Content

[0003] The technical problem solved by this solution is:

[0004] How to solve the problem of a small amount of debris on the surface of the workpiece during friction stir welding, where the surface temperature of the workpiece is high after welding, making it inconvenient to effectively clean the debris?

[0005] The purpose of this utility model can be achieved through the following technical solution: an adjustable angle friction welding device, including a workbench, a flipping table hinged to the top of the workbench, and a support plate fixedly installed at the bottom of the workbench. A guide channel for guiding sewage is provided on the top of the support plate, and the position of the top of the guide channel corresponds to the position of the flipping table. A flushing mechanism for cleaning workpieces is provided on the workbench on one side of the flipping table.

[0006] A further technical improvement of this utility model is that: the flushing mechanism includes a water storage tank fixedly connected to the workbench, a water inlet cylinder is provided on the front of the water storage tank, a first piston and a second piston are slidably arranged on the inner wall of the water inlet cylinder, a transmission rod is fixedly passed through the middle of the second piston, and the top end of the transmission rod is fixedly connected to the first piston.

[0007] A further technical improvement of this utility model is as follows: a rotating seat is fixedly installed on the top of the support plate, and a flipping plate is rotatably arranged on the top of the rotating seat. The bottom end of the transmission rod movably passes through the water inlet cylinder and is rotatably connected to a pressing wheel. The pressing wheel is rolledly connected to one end of the flipping plate. By controlling the extended ends of the two hydraulic cylinders to shorten to their shortest lengths simultaneously, due to the influence of gravity, the flipping table rotates until one end is located at the top of the guide groove, while the extended end of one of the hydraulic cylinders retracts. This, in conjunction with the lever, drives the flipping plate to rotate, causing the pressing wheel and the transmission rod to move upward. At this time, the first piston slides above the inlet end of the drain pipe, and the second piston blocks the outlet end of the water inlet pipe, allowing the clean water located between the first and second pistons to flow through the drain pipe onto the workpiece. This efficiently washes away debris from the workpiece while also cooling the workpiece, thus improving the efficiency of workpiece processing.

[0008] A further technical improvement of this utility model is that: two hydraulic cylinders are fixedly installed on one side of the rotating seat, the two hydraulic cylinders are arranged in a front-to-back manner, and the extended ends of the two hydraulic cylinders are rotatably equipped with support wheels. The support wheels are rolledly connected to the bottom of the tilting table, and the extended end of one of the hydraulic cylinders is slidably connected to the other end of the tilting plate through a lever.

[0009] A further technical improvement of this utility model is that: the middle part of the water inlet cylinder is connected to a water inlet pipe, the input end of the water inlet pipe is connected to the water storage tank, and the output end of the water inlet pipe is located between the first piston and the second piston.

[0010] A further technical improvement of this utility model is that: a drain pipe is connected to the side of the water inlet cylinder away from the water inlet pipe, the output end of the drain pipe is arranged facing the top of the flipping table, and the position of the input end of the drain pipe corresponds to the position of the first piston.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, this invention controls the extension ends of two hydraulic cylinders to shorten simultaneously. Due to gravity, the tilting table rotates until one end is at the top of the guide groove, while the extension end of one hydraulic cylinder retracts. This, combined with a lever, drives the tilting plate to rotate, causing the pressing wheel and transmission rod to move upward. At this time, the first piston slides above the inlet end of the drain pipe, and the second piston blocks the outlet end of the water inlet pipe. This allows the clean water between the first and second pistons to flow through the drain pipe onto the workpiece, efficiently rinsing away debris while also cooling the workpiece and improving processing efficiency.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-4 As shown, an adjustable-angle friction welding device includes a workbench 4, a tilting table 3 hinged to the top of the workbench 4, and a support plate 5 fixedly installed at the bottom of the workbench 4. A guide channel 7 for guiding sewage is fixedly installed on the top of the support plate 5 by a support rod 6. The position of the top of the guide channel 7 corresponds to the position of the tilting table 3. A flushing mechanism 8 for cleaning workpieces is provided on the workbench 4 on one side of the tilting table 3.

[0021] Please see Figure 2 and Figure 3 As shown, the above-mentioned flushing mechanism 8 includes a water storage tank 808 fixedly connected to the workbench 4. A water inlet cylinder 809 is provided on the front of the water storage tank 808. A first piston 813 and a second piston 811 are slidably provided on the inner wall of the water inlet cylinder 809. A transmission rod 807 is fixedly passed through the middle of the second piston 811. The top end of the transmission rod 807 is fixedly connected to the first piston 813.

[0022] Please see Figure 2 and Figure 3As shown, a rotating seat 805 is fixedly installed on the top of the support plate 5. A flipping plate 804 is rotatably mounted on the top of the rotating seat 805. The bottom end of the transmission rod 807 movably passes through the water inlet cylinder 809 and is rotatably connected to the pressing wheel 806. The pressing wheel 806 is rolledly connected to one end of the flipping plate 804. By controlling the extended ends of the two hydraulic cylinders 803 to shorten to their shortest lengths simultaneously, due to the influence of gravity, the flipping table 3 rotates until one end is located at the top of the guide groove 7, while the extended end of one of the hydraulic cylinders 803 retracts. This, in conjunction with the lever 802, drives the flipping plate 804 to rotate, causing the pressing wheel 806 and the transmission rod 807 to move upward. At this time, the first piston 813 slides above the input end of the drain pipe 810, and the second piston 811 blocks the output end of the water inlet pipe 812, allowing the clean water located between the first piston 813 and the second piston 811 to flow through the drain pipe 810 onto the workpiece. This efficiently washes away debris from the workpiece while also cooling it, thus improving the efficiency of workpiece processing.

[0023] Please see Figure 1 and Figure 2 As shown, two hydraulic cylinders 803 are fixedly installed on one side of the rotating seat 805. The two hydraulic cylinders 803 are arranged in a front-to-back manner, and the extended ends of the two hydraulic cylinders 803 are rotatably equipped with support wheels 801. The support wheels 801 are rolledly connected to the bottom of the tilting table 3. The extended end of one of the hydraulic cylinders 803 is slidably connected to the other end of the tilting plate 804 through a lever 802.

[0024] Please see Figure 3 As shown, the water inlet cylinder 809 is connected to a water inlet pipe 812 in the middle. The input end of the water inlet pipe 812 is connected to the water storage tank 808, and the output end of the water inlet pipe 812 is located between the first piston 813 and the second piston 811.

[0025] Please see Figure 1 and Figure 3 As shown, the water inlet cylinder 809 is connected to a drain pipe 810 on the side away from the water inlet pipe 812. The output end of the drain pipe 810 is positioned facing upwards towards the tilting table 3, and the position of the input end of the drain pipe 810 corresponds to the position of the first piston 813.

[0026] Please see Figure 1 and Figure 3 As shown, a friction welding fixture 2 is provided on the side of the workbench 4 away from the water storage tank 808. The friction welding fixture 2 is existing technology.

[0027] Please see Figure 1 As shown, two clamping fixtures 1 for positioning workpieces are fixedly installed on the top of the aforementioned flipping table 3. The clamping fixtures 1 are existing technology.

[0028] Working Principle: In use, the workpiece is first placed on the tilting table 3. At this time, the extended ends of the two hydraulic cylinders 803 are at their longest position. The workpiece is fixed and limited by the two clamping fixtures 1. The friction welding fixture 2 performs a stir friction welding operation on the workpiece. After the stir friction welding of the workpiece is completed, the extended ends of the two hydraulic cylinders 803 are simultaneously shortened to their shortest position. Due to the influence of gravity, the tilting table 3 rotates until one end is at the top of the guide groove 7, while the extended end of one of the hydraulic cylinders 803 retracts, cooperating with the lever 802. The rotating plate 804 is driven to rotate, causing the pressing wheel 806 and the transmission rod 807 to move upward. At this time, the first piston 813 slides above the input end of the drain pipe 810, and the second piston 811 blocks the output end of the water inlet pipe 812, so that the clean water between the first piston 813 and the second piston 811 flows to the workpiece through the drain pipe 810. This efficiently washes away the debris on the workpiece and cools it down, improving the efficiency of workpiece processing. The wastewater carrying the debris will be discharged along the guide groove 7, avoiding contamination of the worktable 4 and the rotating table 3.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
