Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing harmonica tube type liquid cooling plates, in particular to a high-frequency induction coil protection device and high-frequency induction brazing welding equipment. Background Art
[0002] At present, the new energy vehicle industry is developing rapidly, and the demand for harmonica-type liquid cooling plates, the core components of its thermal management system, is increasing year by year. Usually, one plate-type liquid cooling plate needs to be equipped with 9 harmonica-tube liquid cooling plates. The welding and manufacturing equipment of the harmonica-tube liquid cooling plate adopts a high-frequency induction brazing equipment. This type of brazing equipment adopts a structure in which the machine is fixed and the high-frequency induction coil is fixed.
[0003] Due to the different structures of harmonica tube liquid cooling plates, the coil types are also extremely complex, and the specifications and sizes are limited. When placing materials manually, the picking up is extremely difficult. Sometimes designers have to consider both the weldability of the product and the design and manufacturability of the high-frequency induction coil, which is extremely inconvenient. Based on this, the industry has followed the trend of harmonica tube liquid cooling plates and has successively developed a type of CNC semi-automatic high-frequency induction brazing equipment, the high-frequency induction coil of which can move forward and backward and up and down. The purpose of this design is to change the way the coil is fixed, and to make the coil retreat and descend according to the set program to avoid the action, thereby reducing the design difficulty of the high-frequency induction coil, reducing the design cost, and improving the convenience of loading and unloading materials during the manufacturing process of the harmonica tube liquid cooling plate.
[0004] Although the CNC semi-automatic high-frequency induction brazing equipment has solved many problems, it has a big hidden danger. Because the manufacturer does not understand the manufacturing process of the harmonica tube liquid cooling plate, although the program setting has an avoidance action, the actual situation is that the high-frequency induction coil is always in a suspended state, and the high-frequency induction coil is made of brass, which is soft and will soften to a certain extent under repeated heating. Under the action of gravity, the coil position will shift downward after long-term use, and there is also a risk of collision with the high-frequency induction coil during manual loading and unloading.
[0005] Since the high-frequency induction brazing process is extremely sensitive to the up, down, left, and right positions of the high-frequency induction coil, sometimes a few millimeters difference in the relative position of the high-frequency induction coil may affect the harmonica tube base material. The harmonica tube liquid cooling plate has a special structure, and some poor welding areas can only be discovered through metallographic testing methods, and the daily delivery volume is large. Once a batch of defects or even scrap occurs, it will cause very serious consequences. Summary of the invention
[0006] The purpose of the present invention is to provide a high-frequency induction coil protection device for solving at least one of the above-mentioned technical problems.
[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:
[0008] A high-frequency induction coil protection device comprises mounting brackets arranged on both sides of the high-frequency induction coil, each mounting bracket is connected to a tooling for fixing the high-frequency induction coil, and each tooling is provided with a C-shaped slide groove for constraining the running path of the high-frequency induction coil.
[0009] The high-frequency induction coil moves according to the program set by the high-frequency induction brazing host. The structural design of the C-shaped slide groove limits the movement trajectory of the high-frequency induction coil on the one hand, and provides a positioning function for the high-frequency induction coil on the other hand to prevent it from colliding during operation or naturally shifting during use, thereby improving the product welding yield.
[0010] Furthermore, the tooling is a mica tooling.
[0011] Setting up mica tooling can achieve the following beneficial effects: First, it plays a supporting role. The product is assembled from a current collector, a harmonica tube, and a welding ring. If the product is empty, the current collector and the harmonica tube will separate during the welding process, resulting in failure to weld into shape; second, based on the mica material, it has heat insulation and thermal insulation effects. During the brazing process, the product is heated concentratedly and evenly, and there will be no phenomenon of excessive cooling, thereby ensuring the quality of the weld; third, it plays the role of a positioning reference. The current collector is in contact with the plane in the slot, and the heat softening during the brazing process can also ensure good shape and position tolerances.
[0012] Furthermore, the mounting bracket includes a base and a fixing frame fixedly connected to the base, and a trapezoidal notch is provided on the lower surface of the base.
[0013] Furthermore, the tooling is connected to the fixed frame via a pin shaft, and a compression spring is provided through the pin shaft.
[0014] The tooling and the fixed frame are connected by a pin shaft, which improves the installation and disassembly efficiency between the tooling and the fixed frame.
[0015] The compression spring mainly plays a buffering role, and the pin diameter is actually smaller than the through hole, so that part of the deviation can be corrected with the help of the elastic deformation of the compression spring. The source of the deviation is mainly due to the poor processing accuracy of the high-frequency induction coil. In fact, making two coils of the same specifications and sizes may have a large deviation. The main purpose is to adapt to other high-frequency coils.
[0016] Furthermore, at least three mounting holes are formed on the tooling, and corresponding positions of the fixing frame are provided with connecting holes, bolts are passed through the mounting holes and the connecting holes, and a retaining spring is provided between the bolts and the tooling.
[0017] The purpose of the circlip is to limit or control the axial movement of the bolt to ensure that the bolt will not loosen or fall off due to vibration or external force. As a fastener, the circlip can provide an additional locking mechanism to enhance the reliability and safety of the connection.
[0018] Furthermore, two polished rods are provided at the ends of the high-frequency induction coil, and the polished rods are inserted into the C-shaped slide grooves.
[0019] The light rod moves in the C-shaped slide groove to drive the movement of the high-frequency induction coil, and the movement process and the fixing process are more stable.
[0020] Another object of the present invention is to provide a high-frequency induction brazing welding device for solving at least one of the above-mentioned technical problems.
[0021] A high-frequency induction brazing welding device, wherein high-frequency induction coil protection devices are installed on both sides of the high-frequency induction coil of the welding device.
[0022] Furthermore, the welding equipment includes a brazing mainframe housing for controlling the high-frequency induction coil, and the brazing mainframe housing is installed on a moving mechanism, and the moving mechanism drives the mainframe housing to move along three directions of X-axis, Y-axis and Z-axis.
[0023] Furthermore, the moving mechanism includes a first base plate and a second base plate, first sliders are connected to both sides of the lower surface of the first base plate and reciprocate along the guide rail in the X-axis direction under the action of the driving mechanism, second sliders are connected to both sides of the upper surface of the second base plate and reciprocate along the guide rail in the Y-axis direction under the action of the driving mechanism, a guide column is connected between the first base plate and the second base plate, a guide sleeve is arranged outside the guide column, the guide column and the guide sleeve are arranged through the first base plate and reciprocate along the Z-axis direction under the drive of the driving mechanism.
[0024] Beneficial effects:
[0025] In the utility model, mounting brackets and tooling are arranged on both sides of the high-frequency induction coil, and two polished rods are arranged at the ends of the coil and inserted into the C-shaped slide grooves on the tooling. The high-frequency induction coil moves according to the program set by the high-frequency induction brazing host. On the one hand, the movement trajectory of the high-frequency induction coil can be limited, and on the other hand, a positioning effect can be provided for the high-frequency induction coil to prevent it from colliding during operation or naturally deforming due to gravity during use, thereby improving the welding yield of the product.
[0026] The utility model ensures the stability and safety of the high-frequency induction coil during operation by using mica tooling. Mica has good insulation performance and high mechanical strength, and can effectively withstand the vibration and thermal stress generated by the high-frequency induction coil during operation, preventing the high-frequency induction coil from shifting or being damaged due to vibration or thermal expansion. In addition, the mica tooling can also provide good electrical isolation, avoid mutual interference between coils, and ensure that the high-frequency induction coil can work normally and efficiently.
