Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically a grinding device for processing 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 and perform corresponding actions to complete the charging process. On-board chargers are made of cast aluminum alloy and have burrs and protrusions that need to be polished off.

[0003] Chinese utility model patent CN222903626U, published on May 27, 2025, discloses a clamping fixture for grinding the housing of an on-board charger, relating to the field of on-board charger production equipment. The fixture includes a base plate, with first cylinders fixedly connected to the four corners of the upper surface of the base plate. Each first cylinder's output end is rotatably connected to a first fixed shaft. Connecting arms are rotatably connected to both ends of the first fixed shaft. A pressing pad is provided at the lower part of the end of each connecting arm away from the first fixed shaft, and the connecting arm and the pressing pad are connected by bolts. In this utility model, when the housing rests on the upper end of the second cylinder and the support column, a clamping plate inserts into the housing, clamping it inside. Then, the first cylinder pushes the connecting arm upwards, causing the connecting arm to rotate around the second fixed shaft, pressing the pressing pad against the housing and fixing it in place for grinding. After grinding, the first cylinder drives the connecting arm to rotate towards the first cylinder, lifting the pressing pad. The output end of the second cylinder then faces upwards, lifting the housing for easy removal.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing polishing device is an independently used structure that polishes and grinds the fixed on-board charger. This method of polishing a single on-board charger is inefficient when polishing multiple on-board chargers and cannot polish a large number of on-board chargers at the same time. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing polishing devices are independent structures that polish and grind fixed on-board chargers. This method of polishing a single on-board charger is inefficient when polishing multiple on-board chargers and cannot polish a large number of on-board chargers at the same time. The invention provides a polishing device for processing on-board chargers.

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

[0007] The present invention discloses a grinding device for processing on-board chargers, comprising a grinding container for accommodating abrasive and an on-board charger; symmetrical clearance grooves are provided inside the grinding container; a long plate is rotatably connected inside the clearance grooves; a short plate is symmetrically rotatably connected inside the grinding container; a support plate is rotatably connected to the lower ends of the long and short plates; limit grooves are symmetrically provided on the support plate; a clamping plate is slidably sleeved inside the limit grooves; a fastener is threadedly connected to the clamping plate through a through hole; and a vibration motor is fixedly connected to the lower surface of the grinding container.

[0008] Furthermore, a blocking plate is detachably fixed to one end of the grinding container corresponding to the limiting groove.

[0009] Furthermore, handles are inserted between the long plates.

[0010] The grinding device for processing vehicle-mounted chargers provided by this utility model has the following beneficial effects:

[0011] 1. This utility model involves placing a large number of vehicle chargers in rows on the upper surface of a support plate, then rotating fasteners to change the friction between the clamping plate and the support plate, thereby increasing the friction to fix multiple vehicle chargers between two clamping plates. Then, a large amount of abrasive is poured into a grinding container, and a long plate is pushed to lower the support plate, causing the abrasive to submerge the vehicle chargers. Then, a vibrating motor is powered on and runs, carrying the abrasive to move within the grinding container, performing all-round grinding and polishing of the vehicle chargers.

[0012] 2. This utility model uses a reference plate to allow a single clamping plate to hold and fix the on-board charger, making it more convenient and stable to fix the on-board charger. By having the long plate and short plate parallel to each other, when the long plate is pushed or pulled, the support plate and short plate can be moved along with it, allowing the support plate to move from bottom to top, thereby separating the on-board charger and the abrasive, making it more convenient to disassemble and remove the on-board charger.
