A device for removing odor and slag from a friction welding of an on-board charger

Abstract

This utility model relates to the field of new energy vehicle parts manufacturing technology, specifically disclosing a deodorizing and slag-removing device for friction welding of on-board chargers. It includes a flat support plate placed on a friction welding machine; one end of the flat support plate is fixedly connected to a closed box, and the other end is slidably sleeved with a clamping counterweight plate. By placing the flat support plate on the upper surface of the friction welding machine and adjusting its position to align with the friction welding position, and then adjusting the distance between the two movable sleeve plates so that the two clamping plates can be located on both sides of the part, maximizing their proximity to the part, a negative pressure pump generates negative pressure, which flows through two inlet and outlet pipes into the adsorption tank. This adsorption tank adsorbs fumes and particulate matter, which are then filtered through a filter block. When not in use, the square shaft is held to rotate the clamping plates, maintaining a horizontal fit against the upper surface of the friction welding machine, thus not affecting the installation and removal of parts.

Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle parts manufacturing technology, specifically a device for removing odors and slag from friction welding of on-board chargers. Background Technology

[0002] An on-board charger is a charger that is fixedly installed on an electric vehicle. It has the ability to safely and automatically fully charge the electric vehicle's power battery. Based on the data provided by the battery management system (BMS), the charger can dynamically adjust the charging current or voltage parameters, execute corresponding actions, and complete the charging process. Friction welding is a method of welding that uses the heat generated by friction between the contact surfaces of workpieces as a heat source to cause plastic deformation of the workpieces under pressure.

[0003] Chinese utility model patent CN118543953A, published on August 27, 2024, discloses a device for removing slag from friction stir welding of new energy storage tanks, belonging to the field of new energy storage tank processing technology. The device includes a dust collection hood, which comprises a grinding chamber, a dust collection chamber, a dust extraction fan, and a handle. The dust collection chamber is located at the upper end of the grinding chamber, and a handle is located on one side of the dust collection chamber. The dust extraction fan is located at the upper end of the dust collection chamber. This invention solves the problem of existing welding slag grinding resulting in a large amount of splashed metal powder adsorbed and difficult cleaning inside the tank. The proposed new energy storage tank friction stir welding slag removal device directly connects the grinding frame to the dust collection hood, ensuring that the metal dust generated during grinding is immediately sucked into the dust collection hood, reducing dust diffusion. The grinding drive rod pushes the grinding frame to rotate reciprocally, driving the grinding plate to grind, and the grinding plate conforms to the weld bead trajectory, resulting in high grinding precision.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing dust absorption devices are large in size and thickness, making it difficult to fix them under the friction welding equipment. It is necessary to extend the pipe to align with the position of the friction welding. Moreover, it is difficult to absorb larger particles by relying solely on negative pressure dust collection, and some welding slag still falls and cannot be collected. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems of existing dust absorption devices, which are large in size and thickness, making it difficult to fix them under the friction welding equipment. They require extending the pipe to align with the friction welding position, and they cannot absorb heavy particles by relying solely on negative pressure dust collection. There are still welding slags that fall and cannot be collected. This invention provides a vehicle-mounted charger friction welding odor and slag removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a vehicle-mounted charger friction welding deodorization and slag removal device, comprising a flat support plate placed on a friction welding machine; a closed box is fixedly connected to one end of the flat support plate, and a clamping counterweight plate is slidably sleeved on the other end; movable sleeve plates are symmetrically slidably sleeved on the flat support plate; a square shaft is inserted into an opening on the movable sleeve plate; a clamping plate is slidably sleeved on the square shaft; an adsorption groove is formed inside the clamping plate; an inlet and outlet pipe is fixedly connected to the clamping plate and adsorption groove; the end of the inlet and outlet pipe is connected to the closed box; a filter block and a negative pressure pump are inserted in layers inside the closed box; and a sealing cover plate is sealed to the opening of the closed box.

[0008] Furthermore, an indicator wrench is fixed to one end of the square shaft.

[0009] Furthermore, the clamping counterweight plate has a threaded connection to the corresponding planar support plate with a hole.

[0010] This utility model provides a deodorizing and slag-removing device for friction welding of on-board chargers, which has the following beneficial effects:

[0011] 1. This utility model involves placing a flat support plate on the upper surface of a friction welding machine and adjusting its position to align with the friction welding position. Then, the distance between the two movable sleeve plates is adjusted so that the two clamping plates can be located on both sides of the part, allowing them to get as close to the part as possible. Then, the negative pressure pump works to generate negative pressure, which flows through the two inlet and outlet pipes into the adsorption tank. The adsorption tank is used to adsorb dust and particulate matter, which is then filtered through the filter block. When not in use, the square shaft is held to rotate the clamping plates, keeping them horizontally attached to the upper surface of the friction welding machine, thus not affecting the installation and removal of the parts.

[0012] 2. This utility model uses an indicator wrench to rotate, thereby rotating the square shaft and clamping plate. When the friction welding machine is not in use, the clamping plate is kept horizontal and attached to the upper surface of the friction welding machine, without affecting the installation and removal of friction welding parts. Then, during friction welding, the clamping plate is kept vertical to align the friction welding position and receive the welding slag and fumes generated by friction welding.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-4As shown, a vehicle-mounted charger friction welding deodorization and slag removal device includes a flat support plate 1 placed on a friction welding machine; a closed box 10 is fixedly connected to one end of the flat support plate 1, and a clamping counterweight plate 2 is slidably sleeved on the other end; movable sleeve plates 3 are symmetrically slidably sleeved on the flat support plate 1; a square shaft 7 is inserted into an opening on the movable sleeve plate 3; a clamping plate 5 is slidably sleeved on the square shaft 7; an adsorption groove 6 is opened inside the clamping plate 5; an inlet / outlet pipe 9 is fixedly connected to the clamping plate 5 and the adsorption groove 6; the end of the inlet / outlet pipe 9 is connected to the closed box 10; filter blocks 12 and a negative pressure pump 13 are inserted in layers inside the closed box 10; a sealing cover is sealed around the opening of the closed box 10. Plate 11 is used to place the flat support plate 1 on the upper surface of the friction welding machine and adjust its position to align with the friction welding position. Then, the distance between the two movable sleeve plates 3 is adjusted so that the two clamping plates 5 can be located on both sides of the part, allowing them to get as close to the part as possible. Then, the negative pressure pump 13 works to generate negative pressure, which flows through the two inlet and outlet pipes 9 into the adsorption tank 6. The adsorption tank 6 is used to adsorb dust and particulate matter, which is then filtered through the filter block 12. When not in use, the square shaft 7 is held to rotate the clamping plates 5, keeping them horizontally attached to the upper surface of the friction welding machine, so as not to affect the installation and removal of the parts.

[0023] One end of the square shaft 7 is fixed with an indicator wrench 8. The position of the indicator wrench 8 is aligned with the clamping plate 5, so that the square shaft 7 and the clamping plate 5 can be rotated by rotating the indicator wrench 8. This keeps the clamping plate 5 horizontal and attached to the upper surface of the friction welding machine when the friction welding machine is not in use, without affecting the installation and removal of friction welding parts. Then, when friction welding is performed, the clamping plate 5 is kept vertical to align with the friction welding position and to receive the welding slag and fumes generated by friction welding.

[0024] The clamping counterweight plate 2 has a threaded connection to the corresponding flat support plate 1 with a hole. The clamping counterweight plate 2 can be fixed in position on the flat support plate 1 by the bolt, so that it can be adapted to friction welding machines of different widths and can be fixed on the upper surface of the friction welding machine.

[0025] The sealing cover 11 is threadedly connected to the corresponding opening of the sealing box 10 with bolts. The sealing cover 11 can be fixed at the opening of the sealing box 10 by the bolts, so that the sealing is stable.

[0026] The opening distance between the closed cover plate 11 and the closed box 10 is greater than or equal to the thickness of the closed cover plate 11, so that the upper and lower parts of the closed box 10 can be connected, allowing air to flow and be filtered by the filter block 12, thereby adsorbing the fumes and particulate matter generated by friction welding, thus protecting the respiratory health of the operators.

[0027] The movable sleeve 3 is aligned with the flat support plate 1 with a threaded connection to a fastener 4. By rotating the fastener 4, the flat support plate 1 is pressed, thereby fixing the position of the movable sleeve 3 on the flat support plate 1. This can be adjusted according to the diameter of the friction welding item, allowing for close-range adsorption of fumes and particulate matter, thus maximizing the absorption effect.
