Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a friction welding fixture for radiator plates. Background Technology

[0002] In the processing of radiator panels, friction welding is commonly used to fix the panels together or connect them to other components. Friction welding is a welding technology that utilizes the heat generated by friction between workpiece contact surfaces to achieve a solid-state connection. Its core principle is to bring the material to a thermoplastic state through mechanical friction, and then apply pressure to complete the metallurgical bond. Therefore, during friction welding, the radiator panels need to be fixed in a friction welding fixture to prevent the panels from shifting during welding and affecting the welding quality. Existing friction welding fixtures typically fix the radiator panels by using a clamping cylinder to press the panels into the mounting slot of the fixture. However, this method of fixing the radiator panels is often inconvenient when removing them after friction welding, resulting in low processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a friction welding fixture for radiator plates, which can prevent the workpiece from shifting during the welding process and affecting the workpiece processing quality. It can replace manual labor and prevent errors, realize fully automated linkage machine tool system control, and facilitate workpiece removal. It avoids interference from side pressure and top pressure components in the workpiece removal process, thereby improving work efficiency and realizing automation. This solves the problem of low processing efficiency caused by the inconvenience of removing workpieces after friction welding in the friction welding fixture mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A friction welding fixture for radiator panels includes a base plate and a worktable arranged vertically opposite each other. The top of the worktable has several workstations. Each workstation on the top surface of the worktable has a receiving groove for placing workpieces. A side-pressure positioning mechanism and a clamping mechanism are respectively arranged on the periphery of the receiving groove on the top surface of the worktable. The side-pressure positioning mechanism includes a first cylinder mounted on the base plate and a side-pressure member inclined and movably mounted on the worktable. The piston rod of the first cylinder is hinged to the bottom end of the side-pressure member. The clamping mechanism includes a second cylinder mounted on the base plate and a top-pressure member oscillatingly mounted on the worktable. The piston rod of the second cylinder is hinged to the bottom end of the top-pressure member.

[0006] Preferably, the top surface of the worktable has a slot at the edge of the receiving groove, and the bottom wall of the slot has a limiting groove extending to the bottom wall of the receiving groove, so that the bottom end of the workpiece can be inserted.

[0007] Preferably, the top surface of the workbench has an installation groove on one side of the slot; the bottom wall of the installation groove has a through hole; and the top surface of the workbench has several clearance holes on both sides of the installation groove to provide space for the top pressure component to swing.

[0008] Preferably, the side pressure positioning mechanism includes a positioning block, which is embedded in the mounting groove. The positioning block has an inclined guide hole that extends through its upper and lower surfaces, and the side pressure member is movably inserted into the inclined guide hole.

[0009] Preferably, the side pressure member is in the shape of a "7", including an inclined guide portion inserted into the inclined guide hole and a side top connected to the top of the inclined guide portion; a notch is provided on one side of the positioning block for the side top to be inserted.

[0010] Preferably, the pressing mechanism includes a hinge seat, which is installed at the lower part of the clearance hole, and the middle part of the pressing member is provided with a support part perpendicular to the pressing member, which is hinged to the hinge seat.

[0011] Preferably, the pressing mechanism includes a second hinge member, one end of which is hinged to the bottom end of the top pressing member, and the other end is hinged downward to the piston rod of the second cylinder.

[0012] Preferably, the side wall of the receiving groove is embedded with a limiting block opposite to the side pressure member. The limiting block is attached to the side of the workpiece to cooperate with the side pressure member to perform side top positioning of the workpiece.

[0013] Preferably, a plurality of support plates are erected on the periphery of the base plate, and the workbench is connected to the top of the plurality of support plates; a column supporting the bottom surface of the workbench is provided in the middle of the base plate.

[0014] Preferably, a control box is provided on one side of the workbench. The control box is connected to the first cylinder and the second cylinder respectively. The control box controls the operation of the first cylinder and the second cylinder through electrical signals.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the first cylinder drives the side pressure component to tilt and press down until the side of the side pressure component presses against the side of the workpiece; at the same time, the second cylinder drives the top pressure component to swing down until the top pressure component presses against the top surface of the workpiece, thereby completing the positioning and fixing of the workpiece, making the installation more secure, preventing the workpiece from shifting during the welding process and affecting the workpiece processing quality, replacing manual labor and preventing errors, and realizing the control of a fully automated linkage machine tool system; after the friction welding of the workpiece is completed, the second cylinder drives the top pressure component to swing up until the top pressure component is completely separated from the top surface of the workpiece; at the same time, the first cylinder drives the side pressure component to tilt and move upward until the side of the side pressure component is completely separated from the side of the workpiece; because the side pressure component can tilt and move away from the workpiece, and the top pressure component can swing away from the workpiece, the workpiece can be taken out in a straight line from above the worktable, making it convenient to pick up the workpiece, avoiding interference of the side pressure component and the top pressure component in the workpiece removal process, thereby improving work efficiency and realizing automation.

[0027] Please see Figure 1-8A friction welding fixture for radiator panels includes a base plate 1 and a worktable 2 arranged vertically opposite each other. The top of the worktable 2 has several workstations, and each workstation has a receiving groove 21 for placing a workpiece 9. A side-pressing positioning mechanism 3 and a pressing mechanism 4 are respectively arranged around the receiving grooves 21 on the top surface of the worktable 2. The side-pressing positioning mechanism 3 includes a first cylinder 31 mounted on the base plate 1 and a side-pressing member 32 inclined and movably mounted on the worktable 2. The piston rod of the first cylinder 31 is hinged to the bottom end of the side-pressing member 32, and the side-pressing member 32 abuts against the side of the workpiece 9. The pressing mechanism 4 includes a second cylinder 41 mounted on the base plate 1 and a top-pressing member 42 oscillatingly mounted on the worktable 2. The piston rod of the second cylinder 41 is hinged to the bottom end of the top-pressing member 42, and the top-pressing member 42 presses against the top surface of the workpiece 9.

[0028] Please see Figure 1 In this embodiment, there are two side-pressure positioning mechanisms 3, which are respectively arranged on the outer sides of the adjacent sides of the receiving groove 21; there are eight pressing mechanisms 4, which are respectively arranged on the outer sides of the opposite sides of the receiving groove 21. However, this utility model does not limit the number of side-pressure positioning mechanisms 3 and pressing mechanisms 4, and the corresponding number can be set according to the shape and size of the workpiece 9.

[0029] Before friction welding, place workpiece 9 into receiving groove 21; please refer to Figure 3 Then, the first cylinder 31 drives the side pressure member 32 to tilt and press down until the side of the side pressure member 32 presses against the side of the workpiece 9; please refer to Figure 5 Simultaneously, the second cylinder 41 drives the top pressing component 42 to swing downwards until it presses against the top surface of the workpiece 9, thereby completing the positioning and fixing of the workpiece 9. This ensures a more secure installation, preventing the workpiece 9 from shifting during welding and affecting its processing quality. It can replace manual labor and prevent errors, achieving fully automated linkage machine tool system control. Please refer to [link to relevant documentation]. Figure 6 After the friction welding of workpiece 9 is completed, the second cylinder 41 drives the top pressure component 42 to swing upward until the top pressure component 42 is completely detached from the top surface of workpiece 9; please refer to Figure 4 Meanwhile, the first cylinder 31 drives the side pressure member 32 to tilt upward until the side of the side pressure member 32 is completely separated from the side of the workpiece 9. Since the side pressure member 32 can tilt and move away from the workpiece 9, the top pressure member 42 can swing away from the workpiece 9, so that the workpiece 9 can be taken out in a straight line from above the worktable 2. The workpiece is easy to take out, and the side pressure member 32 and the top pressure member 42 avoid interference with the process of taking out the workpiece 9, thereby improving work efficiency and realizing automation.

[0030] Please see Figure 1A plurality of support plates 5 are erected vertically on each side of the base plate 1, and the worktable 2 is connected to the top of the support plates 5. In this embodiment, a column 6 is provided in the middle of the base plate 1, supporting the bottom surface of the worktable 2. The support plates 5 and the column 6 both serve to support the worktable 2, and the column 6 serves to stabilize the worktable 2, preventing it from shaking or deforming due to vibration or other factors during processing. A control box 7 is provided on one side of the worktable 2. The control box 7 is connected to the first cylinder 31 and the second cylinder 41, and controls the operation of the first cylinder 31 and the second cylinder 41 through electrical signals.

[0031] Please see Figure 2 The top surface of the workbench 2 has a slot 22 at the edge of the receiving groove 21. The bottom wall of the slot 22 has a limiting groove 23 extending to the bottom wall of the receiving groove 21. The limiting groove 23 is used to allow the bottom end of the workpiece 9 to be engaged, thus positioning the workpiece 9. The top surface of the workbench 2 has a mounting groove 24 on one side of the slot 22 for mounting the side pressure member 32. The bottom wall of the mounting groove 24 has a through hole 25 for the side pressure member 32 to pass through. The top surface of the workbench 2 has several clearance holes 26 on both sides of the mounting groove 24, providing space for the top pressure member 42 to swing.

[0032] Please see Figure 3-4 as well as Figure 7 The side-pressure positioning mechanism 3 includes a positioning block 33, which is embedded in the mounting groove 24. The positioning block 33 has an inclined guide hole 331 extending through its upper and lower surfaces. The side-pressure member 32 is movably inserted into the inclined guide hole 331. In this embodiment, the side-pressure member 32 is shaped like a "7" and includes an inclined guide portion 321 inserted into the inclined guide hole 331 and a side top 322 connected to the top of the inclined guide portion 321. The positioning block 33 has a notch 332 on one side for the side top 322 to be inserted into. The top surface of the side top 322 is flush with the top surface of the positioning block 33, and the end of the side top 322 abuts against the side of the workpiece 9. The side-pressure positioning mechanism 3 includes a first hinge member 34. One end of the first hinge member 34 is hinged to the bottom end of the inclined guide portion 321, and the other end is hinged downward to the piston rod of the first cylinder 31.

[0033] Please see Figure 1 The side wall of the receiving groove 21 is embedded with a limiting block 8 opposite to the side pressure member 32. The limiting block 8 fits against the side of the workpiece 9 and works with the side pressure member 32 to position the workpiece 9 from the side.

[0034] Please see Figure 4After the friction welding of workpiece 9 is completed, the first cylinder 31 drives the inclined guide 321 to move upward along the axial direction of the inclined guide hole 331 until the side top 322 is completely separated from the side of workpiece 9, so that workpiece 9 can be easily taken out from the receiving groove 21. This is very suitable for automated operation of robotic arms.

[0035] Please see Figure 5-6 as well as Figure 8 The pressing mechanism 4 includes a hinge seat 43, which is installed at the lower part of the clearance hole 26. A support portion 421, perpendicular to the pressing member 42, is provided in the middle of the pressing member 42, and the support portion 421 is hinged to the hinge seat 43. In this embodiment, the hinge seat 43 is T-shaped, and its top end extends into the clearance hole 26 and is hinged to the support portion 421. The pressing mechanism 4 includes a second hinge member 44, one end of which is hinged to the bottom end of the pressing member 42, and the other end is hinged downwards to the piston rod of the second cylinder 41.

[0036] Please see Figure 6 After the friction welding of workpiece 9 is completed, the second cylinder 41 drives the top pressure member 42 to swing upward around the hinge point with the hinge seat 43 until the top pressure member 42 swings to the side away from workpiece 9, so that workpiece 9 can be taken out upward from the receiving groove 21.
