Description

Technical Field

[0001] The utility model relates to the technical field of assembly fixtures, in particular to an assembly fixture for cylinder components of a battery replacement base. Background Art

[0002] Heavy trucks have a large load capacity, high fuel consumption, and huge emissions, so the need for electrification is urgent. The electrification solution for heavy trucks is battery replacement rather than fast charging. This is because the battery capacity of heavy trucks is too large, and if fast charging is used as a solution, the charging power cannot be supported. In this case, the battery replacement solution for container trucks came into being. When replacing the battery, the cylinder needs to be extended to drive the side pin to extend to achieve the connection of the battery holder. When assembling the cylinder and the side pin, an assembly fixture is needed.

[0003] At present, the cotter pin of the battery replacement base cylinder component is difficult to install. Due to the spring resistance inside the side pin, it is necessary to ensure the concentricity of the side pin and the pin cylinder connecting rod fixing hole by external force and then knock the cotter pin in. The operation is cumbersome and time-consuming. Utility Model Content

[0004] In view of this, the utility model provides an assembly fixture for the battery swap base cylinder components, which solves the problem that the cotter pins of the current battery swap base cylinder components are difficult to install. Due to the spring resistance inside the side latch, it is necessary to ensure the concentricity of the side latch and the pin cylinder connecting rod fixing hole by external force and then knock the cotter pin in, which is a cumbersome and time-consuming operation.

[0005] The purpose and effect of the utility model of a battery replacement base cylinder component assembly fixture are achieved by the following specific technical means:

[0006] The utility model provides a battery-changing base cylinder component assembly fixture, which specifically comprises: a fixture base; a concave structure of the fixture base, and a pushing component is installed on the fixture base.

[0007] Optionally, the pushing assembly is composed of a first cylinder, a mounting plate, a sliding rod and a side latch pin limit plate. The first cylinder is fixed to the right end face of the clamp base by a screw. A mounting plate is fixed to the protruding end of the first cylinder. A side latch pin limit plate is fixed to the left end face of the mounting plate by a screw. A limit hole is provided on the side latch pin limit plate.

[0008] Optionally, two sliding rods are threadedly connected to the right end face of the mounting plate, and both sliding rods are cylindrical rod-shaped structures. Both sliding rods are threaded at the right end. Both sliding rods pass through the clamp base. During use, when the second cylinder is damaged and cannot be extended, subsequent assembly is achieved by extending the first cylinder. Nuts can be threadedly connected to the right end of the two sliding rods, and the nuts can be used to limit the movement of the two sliding rods to the left, thereby achieving the extension limit of the first cylinder, which is convenient for accurate alignment of the socket where the fixing pin needs to be plugged.

[0009] Optionally, a cylinder component limit plate is welded to the top surface of the clamp base, and a cylinder assembly is installed on the cylinder component limit plate. The cylinder assembly consists of a second cylinder, a fixed plate, a limit sleeve, a pin cylinder connecting rod, a copper sleeve, a bushing, a side pin, a fixing pin and a spring, and the second cylinder is clamped on the cylinder component limit plate.

[0010] Optionally, a fixing plate is welded on the second cylinder, and the fixing plate is used for the subsequent installation of the second cylinder. A limit sleeve is sleeved at the protruding end of the second cylinder, and a pin cylinder connecting rod is threadedly connected to the protruding end of the second cylinder. A side pin is sleeved on the pin cylinder connecting rod, and a copper sleeve and a bushing are sleeved on the outer side of the side pin.

[0011] Optionally, the pin cylinder connecting rod, copper sleeve, bushing and side latch are all provided with a socket, which is a circular hole structure, and a fixing pin is inserted into the socket.

[0012] Optionally, a spring is sleeved on the pin cylinder connecting rod, and the right end of the spring is in contact with the side latch pin.

[0013] Optionally, two supporting plates are symmetrically welded on the top surface of the clamp base, and the two supporting plates are used to support the side latches. When placing the side latches, the side latches can be directly placed on the two supporting plates for support, and there is no need to manually support the side latches during subsequent assembly.

[0014] Beneficial Effects

[0015] When the device is assembling the cylinder assembly, the side pin can be squeezed by extending the second cylinder. When the side pin is squeezed, the spring is also squeezed. At this time, the side pin, the pin cylinder connecting rod and the socket on the side pin can be aligned. At this time, the fixing pin can be easily inserted into the socket. One worker can complete the insertion of the fixing pin without the need for multiple workers to operate, thereby improving assembly efficiency.

[0016] A pushing component is provided. Through the setting of the pushing component, on the one hand, after the second cylinder is damaged, the side pin can be squeezed out by controlling the extension of the first cylinder. At this time, the fixing pin can also be conveniently inserted into the socket, thereby avoiding the problem of being unable to achieve assembly due to damage to the second cylinder. On the other hand, through the setting of the sliding rod, a nut can be threadedly connected at the right end of the two sliding rods, and the nut can be used to limit the movement of the two sliding rods to the left, thereby realizing the extension limit of the first cylinder, which is convenient for accurately aligning the socket into which the fixing pin needs to be inserted.

[0017] A supporting plate is provided. Through the provision of the supporting plate, when placing the side latches, the side latches can be directly placed on two supporting plates for support, and there is no need to manually support the side latches during subsequent assembly.
