Based on the data provided by the battery management system (BMS), the charger can dynamically adjust the charging current or voltage parameters, perform corresponding actions, and complete the charging process.

[0003] Chinese utility model patent CN222680709U, published on March 28, 2025, discloses a tooling fixture for processing vehicle-mounted chargers. The fixture includes a base with a positioning device on its surface and an adjustment device installed at the edge of its side wall. The positioning device includes a rectangular frame fixedly connected to the side wall of the base. A first circular hole is provided on one side of the rectangular frame, and a bidirectional screw is rotatably connected inside the first circular hole. The bidirectional screw is rotatably connected inside the rectangular frame. The surface of the bidirectional screw is symmetrically threaded to two L-shaped rods. Each of the two L-shaped rods has a rectangular groove on its side wall and multiple insertion holes on its surface. A circular hole block is slidably connected inside the rectangular groove, and a clamping block is fixedly connected to one side of the circular hole block. A pin passes through the insertion hole and slidably connects to the inside of the circular hole block. This utility model provides a tooling fixture for processing vehicle-mounted chargers that facilitates the fixing of various models of vehicle-mounted chargers.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing technology uses fixtures in the processing, which cannot be combined with the production line to achieve continuous processing of continuous clamping and unloading, resulting in reduced efficiency during continuous processing. Furthermore, during the installation and removal of the on-board charger, the weight of the on-board charger makes it easy to cause collisions and falls. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems of existing processing fixtures, which cannot be matched with the production line to achieve continuous clamping and unloading, resulting in reduced efficiency during continuous processing. Furthermore, during the installation and disassembly of the on-board charger, the weight of the on-board charger makes it easy to cause collisions and falls. The present invention provides a clamping fixture for processing on-board chargers.

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

[0007] This utility model discloses a clamping fixture for processing an on-board charger, comprising a fixed base; a clearance groove is provided on the fixed base; a conveying unit is provided in the clearance groove; a first fixed seat is fixedly connected at intervals in the fixed base; a hydraulic push rod is rotatably connected in the first fixed seat; a second fixed seat is rotatably connected to the end of the hydraulic push rod; a clamping block is fixedly connected to the second fixed seat; a stepped groove is provided in the clamping block; a pen-shaped cylinder is inserted into the stepped groove; a push plate is fixedly connected to the movable end of the pen-shaped cylinder; and a discharge groove is provided on the fixed base corresponding to the stepped groove.

[0008] Furthermore, the fixed base has multiple countersunk holes extending through it.

[0009] Furthermore, the mounting base is made of metal.

[0010] The clamping fixture for processing on-board chargers provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses a hydraulic push rod to move a clamping block to clamp the on-board charger onto a fixed base. At this point, only the upper part of the on-board charger is exposed, which facilitates processing using a machining center or grinding machine. Then, the hydraulic push rod moves the clamping block, and a pen-shaped cylinder pushes the push plate and the processed on-board charger. Under the action of gravity, the charger descends into the next stepped groove and then falls into the discharge groove for discharge. This realizes the function of automatically discharging the on-board charger, thus increasing efficiency when processing multiple on-board chargers continuously.

[0012] 2. This utility model maintains precise linear movement of the clamping block by sliding the clamping block and the fixed base. By filling the space between the clamping block and the fixed base with lubricant, resistance and noise can be reduced, while improving the stability and accuracy of long-term operation.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] Please see Figure 1-3 As shown, a clamping fixture for processing on-board chargers includes a fixed base 1 that can be detachably fixed to a machining center or grinding machine; a clearance groove 2 is provided on the fixed base 1; a conveying unit 3 is provided in the clearance groove 2, and on-board chargers to be processed are placed at intervals on the conveying unit 3, and can be driven into the fixed base 1 by the conveying unit 3; a first fixed seat 4 is fixedly connected at intervals in the fixed base 1; a hydraulic push rod 5 is rotatably connected in the first fixed seat 4; a second fixed seat 6 is rotatably connected to the end of the hydraulic push rod 5; a clamping block 7 is fixedly connected to the second fixed seat 6; a stepped groove 8 is provided in the clamping block 7; a pen-shaped cylinder 10 is inserted into the stepped groove 8; the pen-shaped cylinder 10... The movable end of cylinder 10 is fixedly connected to push plate 9; the fixed base 1 has a discharge groove 11 corresponding to the stepped groove 8. The hydraulic push rod 5 moves the clamping block 7 to clamp the on-board charger on the fixed base 1. At this time, only the upper part of the on-board charger is exposed, which makes it convenient to use a machining center or grinding machine for processing. Then the hydraulic push rod 5 moves the clamping block 7 to move, and then the pen-shaped cylinder 10 pushes the push plate 9 and the processed on-board charger. Then, under the action of gravity, it falls into the next stepped groove 8 and then falls into the discharge groove 11 for discharge. This realizes the function of automatically discharging the on-board charger, thus making it more efficient when processing multiple on-board chargers continuously.

[0022] The fixed base 1 has multiple countersunk holes, which can be used to fix it stably on the machining center or lathe, thus facilitating the processing of the on-board charger.

[0023] The fixed base 1 is made of metal, which allows it to be stably fixed on various processing equipment, thus meeting the processing needs of machining centers or grinding machines.

[0024] The clamping block 7 is slidably inserted into the fixed base 1. Through the sliding connection between the clamping block 7 and the fixed base 1, the linear movement of the clamping block 7 is kept accurate. By filling the space between the clamping block 7 and the fixed base 1 with lubricant, resistance and noise can be reduced, while the stability and accuracy of long-term operation can be improved.

[0025] The upper surface of the conveying unit 3 is flush with the upper surface of the fixed base 1. After the on-board charger is placed on the upper surface of the conveying unit 3, it can be smoothly conveyed into the stepped groove 8 on the clamping block 7. Then, wait for the clamping block 7 to be pushed by the hydraulic push rod 5, and then clamp the on-board charger for fixation. At this time, the upper surface of the on-board charger can be processed.

[0026] The push plate 9 is made of rigid plastic, which prevents it from squeezing and damaging the on-board charger, while also being able to hold the on-board charger in place.
