Description

Technical Field

[0001] The utility model relates to the field of production equipment for on-vehicle chargers, in particular to a clamping tool for grinding the shell of an on-vehicle charger. Background Technique

[0002] The on-vehicle charger is mainly used to complete the output conversion from alternating current to direct current. The power supply is mainly applied in the fuel cell communication power supply system. As the power core part of the fuel cell communication power supply system, it determines the input and output indexes of the entire communication power supply system. It can also be widely applied to the power supply systems of various communication devices such as switching equipment and mobile base stations. The on-vehicle charger refers to a charger fixedly installed on an electric vehicle and is one of the indispensable important components of a pure electric vehicle.

[0003] When the existing clamping tool for grinding clamps the shell of the on-vehicle charger, in order to make the clamping effect better, the area of the tool clamped on the shell is too large, covering the surface of the shell and affecting the grinding area. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to provide a clamping tool for grinding the shell of an on-vehicle charger.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a clamping tool for grinding the shell of an on-vehicle charger, including a bottom plate. Four corners of the upper surface of the bottom plate are fixedly connected with first cylinders. The output ends of the first cylinders are all rotatably connected with first fixed shafts. Both ends of the first fixed shafts are rotatably connected with connecting arms. The lower part of the end of the connecting arm far from the first fixed shaft is provided with a pressing pad, and the connecting arm and the pressing pad are connected by bolts. The middle part of the connecting arm is rotatably connected with a second fixed shaft. Both ends of the second fixed shaft are rotatably connected with connecting plates. The lower ends of the connecting plates are rotatably connected with third fixed shafts. The middle part of the third fixed shaft is rotatably connected with a fulcrum seat. Both ends of the fulcrum seat are fixedly connected to the upper ends of the first cylinders by bolts.

[0006] Snap rings are clamped at both ends of the first fixed shaft, the second fixed shaft and the connecting plates;

[0007] As a further description of the above technical solution:

[0008] Two groups of fixed seats are connected to the upper surface of the bottom plate, and the fixed seats are fixedly connected to the upper surface of the bottom plate by bolts. The fixed seats are located at both ends of the diagonal line of the upper surface of the bottom plate. The upper ends of the fixed seats are fixedly connected with second cylinders. Through the fixed seats, the second cylinders are fixed at designated positions.

[0009] As a further description of the above technical solution:

[0010] On the upper surface of the bottom plate, support columns are fixedly connected to both diagonals of the other side. A housing is provided at the upper ends of the support columns and the second cylinder. The housing can be supported by the support columns and the second cylinder.

[0011] As a further description of the above technical solution:

[0012] On the middle part of the upper surface of the bottom plate, clamping plates are connected by bolts on all four sides. And the upper ends of the clamping plates are all bent. The clamping plates all squeeze the inner side surface of the housing. The clamping plates are made of stainless steel. After the housing is placed on the upper ends of the second cylinder and the support columns, the clamping plates will insert into the interior of the housing, thereby clamping the interior of the housing.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, first, when the housing lands on the upper ends of the second cylinder and the support columns, the clamping plates will insert into the interior of the housing, thereby clamping the interior of the housing. Then, the first cylinder pushes the connecting arm upward, and the connecting arm rotates around the second fixed shaft, so that the pressing pad presses the housing, thereby fixing the housing, which is convenient for grinding the housing. After grinding is completed, the first cylinder drives the connecting arm to rotate towards the first cylinder, so that the pressing pad is lifted. The output end of the second cylinder moves upward to jack up the housing, thereby facilitating the removal of the housing. Description of the Drawings
