Description

Technical Field

[0001] The utility model relates to the technical field of assembly and locking, in particular to a locking device for assembling a plastic fuel tank and an oil pump chuck. Background Art

[0002] When producing plastic fuel tanks, plastic fuel tank manufacturers need to place the oil pump into the plastic fuel tank and lock the oil pump chuck with the plastic fuel tank so that the oil pump is fixed in the plastic fuel tank.

[0003] At present, the locking operation of the oil pump chuck and the plastic fuel tank is mainly divided into two methods: manual locking or semi-automatic locking. Manual locking is to place the locking tool on the oil pump chuck (the oil pump chuck is provided with a force-bearing recess), and manually rotate the oil pump chuck through the locking tool to lock the plastic fuel tank and the oil pump chuck. This method has low working efficiency and cannot guarantee the quality of locking. Semi-automatic locking is to manually place the locking disk of the locking device on the oil pump chuck (through the force-bearing recess) for positioning, and then manually start the locking device. The locking disk of the locking device drives the oil pump chuck to rotate, thereby locking the oil pump chuck and the plastic fuel tank. This method also requires manual work and is costly. Summary of the invention

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a locking device for assembling a plastic fuel tank and a fuel pump chuck with high locking efficiency and low cost.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] A locking device for assembling a plastic fuel tank and an oil pump chuck comprises a plastic fuel tank, an oil pump chuck, a locking module, a power module, and a lifting module; the oil pump chuck is provided with a force-bearing concave portion and is rotatably and detachably connected to the plastic fuel tank;

[0007] The locking module is arranged above the oil pump chuck;

[0008] The power module is connected to the locking module to drive the locking module to rotate;

[0009] The lifting module is connected with the power module, drives the power module and the locking module to rise and fall, and cooperates with the power module to make the locking module snap into the force-bearing recess.

[0010] This technical solution drives the power module and the locking module down through the lifting module. When the locking module is inserted into the force-bearing concave portion of the oil pump chuck, the power module drives the locking module to rotate, thereby locking the oil pump chuck and the plastic fuel tank. When the oil pump chuck and the plastic fuel tank are locked, the lifting module drives the power module and the locking module up again, and the locking module leaves the oil pump chuck. No manual operation is required throughout the process, and it has the advantages of high locking efficiency and low cost.

[0011] Further, the power module includes a tightening gun and a bracket seat;

[0012] The support seat is connected to the lifting module;

[0013] The tightening gun is installed on the bracket seat, and the rotating shaft of the tightening gun passes through the bracket seat and is connected with the locking module to drive the locking module to rotate.

[0014] Furthermore, it also includes a positioning plate and a universal joint;

[0015] The top of the plastic fuel tank is provided with a groove;

[0016] The universal joint is connected between the power module and the bracket seat;

[0017] The bottom of the positioning plate matches the groove. The positioning plate is installed at the bottom of the bracket seat and is located at the periphery of the locking module and is concentrically arranged with the locking module.

[0018] In this technical solution, when the lifting module drives the power module and the locking module to descend, and the positioning plate contacts the groove on the top of the plastic fuel tank, the positioning plate and the groove cooperate to guide, and with the assistance of the universal joint, the locking module faces the oil pump chuck. It is suitable for the situation where the locking module cannot completely face the oil pump chuck.

[0019] Furthermore, the locking module includes a locking disc and a locking claw portion matching the force-bearing recess;

[0020] The locking claw is connected to the bottom of the locking disc.

[0021] Further, the locking claw portion includes a plurality of locking columns;

[0022] Multiple locking columns are evenly arranged along the edge of the locking disc to facilitate uniform force output during the locking process.

[0023] Furthermore, the lifting module is a lifting cylinder module.

[0024] Furthermore, a through hole is provided on the side of the positioning plate, so as to facilitate checking whether the locking module is inserted into the force-bearing recess.

[0025] Compared with the prior art, the principles and advantages of this technical solution are as follows:

[0026] 1. This technical solution drives the power module and the locking module to descend through the lifting module. When the locking module is inserted into the force-bearing concave portion of the oil pump chuck, the power module drives the locking module to rotate, thereby locking the oil pump chuck and the plastic fuel tank. After the oil pump chuck and the plastic fuel tank are locked, the lifting module drives the power module and the locking module to rise, and the locking module leaves the oil pump chuck. No manual operation is required throughout the process, and it has the advantages of high locking efficiency and low cost.

[0027] 2. In this technical solution, when the lifting module drives the power module and the locking module to descend, and the positioning plate contacts the groove on the top of the plastic fuel tank, the positioning plate and the groove cooperate to guide, and with the assistance of the universal joint, the locking module faces the oil pump chuck. It is suitable for the situation where the locking module cannot completely face the oil pump chuck. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The utility model is further described below in conjunction with specific implementation methods:

[0038] like Figures 1 to 6 As shown, the locking device for assembling a plastic fuel tank 1 and an oil pump chuck 2 described in this embodiment includes a plastic fuel tank 1, an oil pump chuck 2, a locking module, a power module, a lifting module 10, a positioning plate 6 and a universal joint 7.

[0039] The top of the plastic fuel tank 1 is provided with a groove 12 .

[0040] The oil pump chuck 2 is provided with a force-bearing recess 3 and is rotatably and detachably connected to the plastic fuel tank 1 .

[0041] The lifting module 10 is a lifting cylinder module.

[0042] The power module includes a tightening gun 4 (the rotating shaft of the tightening gun 4 is elastic, which is the existing technology) and a bracket seat 5; the bracket seat 5 is connected to the cylinder rod of the lifting cylinder module through a universal joint 7; the tightening gun 4 is installed on the bracket seat 5, and the rotating shaft of the tightening gun 4 passes through the bracket seat 5 and is connected to the locking module, driving the locking module to rotate.

[0043] The locking module is arranged above the oil pump chuck 2, and includes a locking disc 8 and a locking claw 9 matching the force-bearing recess 3; the locking disc 8 is connected to the rotating shaft of the tightening gun 4; the locking claw 9 includes six locking columns, which are all connected to the bottom of the locking disc 8 and arranged along the edge of the locking disc 8.

[0044] The bottom of the positioning disk 6 matches the groove 12, and the positioning disk 6 is installed at the bottom of the bracket seat 5 and is located at the periphery of the locking disk 8 and is concentrically arranged with the locking disk 8. In addition, a through hole 11 is opened on the side of the positioning disk 6 to facilitate checking whether the locking module is inserted into the force-bearing recess 3.

[0045] The working principle of this embodiment is as follows:

[0046] When it is necessary to lock the plastic fuel tank 1 and the oil pump chuck 2, the lifting cylinder module works to drive the power module and the locking module to descend. When the lifting module 10 drives the power module and the locking module to descend, and the positioning plate 6 contacts the groove 12 on the top of the plastic fuel tank 1, the positioning plate 6 and the groove 12 cooperate to play a guiding role, and with the assistance of the universal joint 7, the locking module is facing the oil pump chuck 2. When the locking module is facing the oil pump chuck 2, the tightening gun 4 is started, driving the locking disc 8 and the locking claw 9 to rotate. When the six locking columns of the locking claw 9 rotate to the top of the force-bearing recess 3 corresponding to the oil pump chuck 2 (during the rotation process, the rotating shaft of the tightening gun 4 is in a compressed state), the six locking columns of the locking claw 9 will fall into the force-bearing recess 3 corresponding to the oil pump chuck 2. At this time, the tightening gun 4 still drives the locking disc 8 and the locking claw 9 to rotate, thereby driving the oil pump chuck 2 to rotate (the plastic fuel tank 1 is stationary), and finally locking the plastic fuel tank 1 and the oil pump chuck 2. After the locking is completed, the cylinder rod of the lifting cylinder module retracts, driving the locking module and the power module to rise back to their original positions.

[0047] This embodiment does not require manual operation throughout the entire process and has the advantages of high locking efficiency and low cost.

[0048] In addition, when the lifting module 10 drives the power module and the locking module to descend, and the positioning plate 6 contacts the groove 12 on the top of the plastic fuel tank 1, the positioning plate 6 and the groove 12 cooperate to play a guiding role, and with the assistance of the universal joint 7, the locking module is made to face the oil pump chuck 2. It is suitable for the situation that the locking module cannot completely face the oil pump chuck 2.

[0049] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
