Abstract
Description
Technical Field
[0001] This application relates to the field of welding fixture technology, specifically a welding fixture for automotive radiator cores. Background Technology
[0002] The car radiator, also known as the car water tank, is an indispensable and important component of the car's cooling system. Its main function is to dissipate excess heat from the engine in order to maintain the engine's normal operating temperature.
[0003] Application No. 202321845273.7 discloses a welding fixture for automotive radiator cores, including a fixed frame, a fixed groove, movable blocks, and a servo motor. By setting an adjustment mechanism, the radiator core is placed on the fixed plate of the movable plate. The starting cylinder drives the two movable blocks and the movable plate to move to opposite sides via the connecting block, thereby fixing the radiator core. It can be used for radiator cores of different sizes. The starting servo motor can drive the movable plate and the radiator core to rotate, which facilitates the welding operation of the radiator core.
[0004] However, in practice, it has the following drawbacks:
[0005] Although the device uses two movable blocks and a movable plate to move relative to each other to fix the radiator core, different radiator cores have different widths. The device can only adapt to the left and right width of the radiator core, and cannot adjust the front and back width. This may result in the spacing being too small to accommodate the clamping, affecting the practicality of the device. Utility Model Content
[0006] The purpose of this application is to provide a welding fixture for automotive radiator cores, which solves the problem mentioned in the background art that although two movable blocks and a movable plate are used to move relative to each other to fix the radiator core, different radiator cores have different widths, and the device can only adapt to the left and right width of the radiator core. It cannot adjust the front and back width, which may result in the spacing being too small to adapt to clamping and affect the practicality of the device.
[0007] To achieve the above objectives, this application provides the following technical solution: a welding fixture for automotive radiator cores, comprising a base, a rotating shaft, a lead screw, a clamping plate, and a telescopic rod. A turntable is fixedly installed at the center of the top of the base, and a support frame is fixedly connected to the top of the turntable. Rotating shafts are movably installed on the left and right inner sidewalls of the support frame. The sidewalls of the rotating shafts are fixedly connected to sliding blocks, and the sliding blocks are laterally connected to the surface of the telescopic rod. The two ends of the telescopic rod are respectively fixedly connected to one end of the sidewall of a first fixed rod and a second fixed rod. A strip groove is provided on the sidewall of the first fixed rod and the second fixed rod on opposite sides, and a lead screw is laterally fixedly installed on the inner side of the strip groove.
[0008] In this technical solution, motors one and two, along with clamping plates, can clamp and limit the left and right ends of the radiator core. When motors one and two are powered on, they start, driving the lead screws inside the first and second fixing rods to rotate. The first threaded block moves laterally during the rotation of the lead screws, thus moving the right-side clamping plate. The second threaded block moves the left-side clamping plate laterally, adjusting the position to clamp the radiator core. The distance between the radiator core and the clamping plate can be adjusted on both sides using a telescopic rod, adjusting bolts, and sliding blocks. The telescopic rod can be extended or shortened by twisting the adjusting bolts, thus adjusting the distance between the first and second fixing rods at both ends. The clamping plate is also designed with telescopic joints at both ends. When the distance between the first and second fixing rods changes, its length will adjust accordingly. Then, the sliding block can be slid to keep it always in the center of the telescopic rod. Combined with the lateral movement of the clamping plate, it can adapt to radiator cores of various sizes, improving the practicality of the device. At the same time, by turning the switch, the shaft, and the turntable, the radiator core can be rotated freely. The turntable can drive the support frame and the radiator core to move in a circular motion together, while turning the switch can loosen the shaft to rotate in two directions, allowing the radiator core to be adjusted to any angle, thus improving the convenience and practicality of the device.
[0009] As an optional solution to the technical solution of this application, a No. 1 sleeve block and a No. 1 threaded block are respectively sleeved and connected to the left and right sides of the lead screw surface inside the groove of the No. 1 fixing rod.
[0010] As an optional solution to the technical solution of this application, the screw surface on the inner side of the groove of the second fixing rod is threaded with a second threaded block and sleeved with a second sleeve block on the left and right sides respectively.
[0011] As an optional solution to the technical solution of this application, a No. 1 motor is fixedly installed at the right end of the No. 1 fixing rod, and a No. 2 motor is fixedly installed at the left end of the No. 2 fixing rod. The tail ends of the drive shafts of the No. 1 motor and the No. 2 motor are respectively fixedly connected to the lead screws on the inner sides of the No. 1 fixing rod and the No. 2 fixing rod.
[0012] As an optional solution to the technical solution of this application, clamping plates are fixedly connected between the No. 1 threaded block and the No. 2 socket block, as well as between the No. 2 threaded block and the No. 1 socket block.
[0013] As an optional solution to the technical solution of this application, the top end of the sliding block is threaded with a fixing bolt, and the top end of the telescopic rod is threaded with an adjusting bolt.
[0014] As an optional solution to the technical solution of this application, a torsion switch is movably installed on the upper part of the left and right outer side walls of the support frame, and the torsion switch is movably connected to the rotating shaft.
[0015] Compared with the prior art, the beneficial effects of this application are as follows:
[0016] 1. This application allows for adjustment of the spacing on both the front and rear sides via a telescopic rod, adjusting bolt, and sliding block. The telescopic rod can be extended or shortened by twisting the adjusting bolt, thereby adjusting the spacing between the first and second fixed rods at both ends. The clamping plate is also designed with telescopic sleeves at both ends, and its length will adjust accordingly when the spacing between the first and second fixed rods changes. Then, the sliding block can be slid to keep it always in the center of the telescopic rod. Combined with the lateral movement of the clamping plate, it can adapt to radiator cores of various sizes, thus improving the practicality of the device.
[0017] 2. This application allows the radiator core to rotate freely via a toggle switch, a rotating shaft, and a turntable. The turntable can drive the support frame and the radiator core to move in a circular motion together, while the toggle switch can be loosened to cause the rotating shaft to rotate in two directions, thereby allowing the radiator core to be adjusted to any angle, improving the convenience and practicality of the device.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.
[0024] like Figure 1As shown, a welding fixture for automotive radiator cores includes a base 1, a rotating shaft 5, a lead screw 10, a clamping plate 12, and a telescopic rod 13. A turntable 2 is fixedly installed at the center of the top of the base 1. A support frame 3 is fixedly connected to the top of the turntable 2. The rotating shaft 5 is movably installed on the left and right inner side walls of the support frame 3. The side wall of the rotating shaft 5 is fixedly connected to a sliding block 6, and the sliding block 6 is laterally connected to the surface of the telescopic rod 13. The two ends of the telescopic rod 13 are fixedly connected to one end of the side wall of the first fixed rod 8 and the second fixed rod 11, respectively. The turntable 2 can rotate freely to drive the support frame 3 to move in a circular motion.
[0025] like Figure 1 As shown, the top of the sliding block 6 is threaded with a fixing bolt 7, the top of the telescopic rod 13 is threaded with an adjusting bolt 131, and a torsion switch 4 is movably installed on the upper part of the left and right outer walls of the support frame 3. The torsion switch 4 is movably connected to the rotating shaft 5. When the torsion switch 4 is tightened, it will squeeze the rotating shaft 5. When it is loosened, the rotating shaft 5 can rotate freely.
[0026] like Figure 1 and Figure 2 As shown, the sidewalls of the first fixing rod 8 and the second fixing rod 11 on opposite sides are provided with strip grooves 9. A threaded rod 10 is horizontally fixedly installed on the inner side of the strip groove 9. Only half of the surface of the threaded rod 10 is provided with threaded grooves, which can ensure that the first socket block 803 and the second socket block 113 can slide freely on the other half.
[0027] like Figure 2 As shown, on the left and right sides of the surface of the lead screw 10 inside the groove 9 of the first fixing rod 8, a first sleeve block 803 is connected and a first thread block 802 is threadedly connected. On the left and right sides of the surface of the lead screw 10 inside the groove 9 of the second fixing rod 11, a second thread block 112 is threaded and a second sleeve block 113 is connected.
[0028] like Figure 2 As shown, a No. 1 motor 801 is fixedly installed on the right end of the No. 1 fixed rod 8, and a No. 2 motor 111 is fixedly installed on the left end of the No. 2 fixed rod 11. The tail ends of the drive shafts of the No. 1 motor 801 and the No. 2 motor 111 are fixedly connected to the lead screws 10 on the inner side of the No. 1 fixed rod 8 and the No. 2 fixed rod 11, respectively.
[0029] like Figure 3 As shown, clamping plates 12 are fixedly connected between threaded block 802 and socket block 113, and between threaded block 112 and socket block 803. The clamping plates 12 are configured with two sockets, and the diameter difference is very small, so the drop at the socket can be ignored.
[0030] In practical use, the first motor 801, the second motor 111, and the clamping plate 12 can limit and clamp the left and right ends of the radiator core. After the first motor 801 is powered on, it starts and drives the lead screws 10 on the inner side of the first fixing rod 8 and the second fixing rod 11 to rotate. The first threaded block 802 moves laterally when the lead screw 10 rotates, thereby driving the right clamping plate 12 to move together. The second threaded block 112 drives the left clamping plate 12 to move laterally. After adjusting to the appropriate position, the radiator core is clamped. The distance can be adjusted on the front and rear sides by the telescopic rod 13, the adjusting bolt 131, and the sliding block 6. The telescopic rod 13 can be extended or shortened by twisting the adjusting bolt 131, thereby allowing the first fixing rods at both ends to be clamped. The distance between the first fixed rod 8 and the second fixed rod 11 is adjusted. The clamping plate 12 is also set with telescopic sleeves at both ends. When the distance between the first fixed rod 8 and the second fixed rod 11 changes, the length will be adjusted accordingly. Then, the sliding block 6 can be slid to keep it always in the center of the telescopic rod 13. With the left and right lateral movement of the clamping plate 12, it can adapt to radiator cores of various sizes, thus improving the practicality of the device. At the same time, by turning the switch 4, the rotating shaft 5 and the turntable 2, the radiator core can be rotated freely. The turntable 2 can drive the support frame 3 and the radiator core to move in a circle together. The switch 4 can be turned loose to make the rotating shaft 5 rotate in two directions, so that the radiator core can be adjusted to any angle, thus improving the convenience and practicality of the device.
