The fuel tank oil pump locking disc checking fixture can be used for checking whether the inner diameter, the outer diameter, the width of the locking position, the height of the locking position and the levelness of the locking position of the locking disc 7 are qualified or not. The main body component 1, the inner diameter detection component 3, the outer diameter and locking position width detection component 4, the locking position height and levelness reference component 5 and the locking position height and levelness detection component 6 can be designed to be the most suitable size according to the inner/outer diameter, width/height size of the oil pump mounting locking disc of the fuel tanks in different countries.
The locking disk pressing member 2 is used to press the locking disk 7 against the body member 1, thereby establishing a detection state. FIG. 2 is a schematic diagram of a detection state of a fuel tank oil pump locking disc detection tool according to an embodiment of the utility model. The inner diameter detection member 3, the outer diameter and locking position width detection member 4, and the locking position height and levelness reference member 5 are provided on the main body member 1, and the locking disk 7 is attached to the inner diameter detection member 3, the outer diameter and locking position width detection member 4, and the locking position height and levelness reference member 5 in a detection state where the locking disk pressing member 2 presses the locking disk 7 against the main body member 1.
Fig. 3 is a schematic structural view of an inner diameter detecting member, an outer diameter and locking position width detecting member, and a locking position height and levelness detecting member according to an embodiment of the present invention. With reference to fig. 1 and 3, the inner diameter detecting member 3 can detect whether the inner diameter of the locking disk 7 is acceptable; the outer diameter and locking position width detection member 4 can detect whether the outer diameter of the locking disc and the width of the locking position of the locking disc are qualified. If the inner diameter, outer diameter, or width of the locking position of the locking disk 7 is not satisfactory, the locking disk 7 cannot be inserted into the body member 1.
The locking position height and levelness reference member 5 serves as a reference for detecting the height and levelness of the locking position of the locking disk. The locking position height and levelness detection means 6 is used for detecting whether the height detection gap and the levelness detection gap are qualified or not, thereby detecting whether the height and the levelness of the locking position of the locking disc 7 are qualified or not. Fig. 4 is a schematic diagram illustrating a detection principle of the locking position height and levelness detecting member according to an embodiment of the present invention. Referring to fig. 1 and 4, in a detection state where the inner diameter, the outer diameter and the width of the locking position of the locking disk 7 are acceptable and the locking disk pressing member 2 presses the locking disk 7 against the main body member 1, the locking disk 7 is attached to the inner diameter detecting member 3, the outer diameter and locking position width detecting member 4 and the locking position height and levelness reference member 5, a height detecting gap 11 of the locking position of the locking disk is formed between the locking disk pressing member 2 and the locking disk 7, and a levelness detecting gap 12 of the locking position of the locking disk is formed between the locking disk 7 and the main body member 1. The locking position height and levelness detection member 6 can detect whether the height and levelness of the locking position of the tightening plate 7 are qualified or not by detecting whether the height detection gap 11 and the levelness detection gap 12 are qualified or not.
In one embodiment, the locking position height and levelness detecting member 6 is a go/no-go gauge, and when the height detecting gap 11 and the levelness detecting gap 12 are qualified, the go/no-go gauge is turned on and turned off. The number of the go-no-go gauges is two, for example.
As shown in fig. 1, the fuel tank oil pump locking disc checking fixture in the embodiment of the utility model further comprises a checking fixture base 8, and the main body component 1 is installed on the checking fixture base 8. The levelness of the gauge base 8 is, for example, 0.03 mm/m. The checking fixture base 8 is provided with a positioning mechanism for placing the locking disc pressing component 2 and the locking position height and levelness detection component 6 in a non-detection state. The positioning mechanism can be a positioning groove for placing the locking disc pressing component 2 or a positioning bracket for placing the locking position height and levelness detection component 6.
In one embodiment, the main body member 1 may be provided with a positioning pin, the locking disk pressing member 2 is provided with a positioning hole, and the locking disk pressing member 2 is connected with the main body member 1 through the cooperation of the positioning pin and the positioning hole. The number of the positioning pins and the number of the positioning holes can be two respectively. Further, a screw hole may be formed in the main body member 1, a screw rod may be disposed on the locking disk pressing member 2, and the locking disk pressing member 2 may be connected to the main body member 1 through the cooperation of the screw rod and the screw hole. When the screw shaft is screwed to the screw hole, it can be confirmed that the locking disk 7 is attached to the inner diameter detection member 3, the outer diameter and locking position width detection member 4, and the locking position height and levelness reference member 5, thereby preventing erroneous judgment caused by the locking disk 7 not being attached to each member.
The detection process of the fuel tank oil pump locking disc detection tool provided by the embodiment of the utility model is as follows: firstly, lifting the locking disc pressing component 2, putting the locking disc 7 into the main body component 1, checking whether the inner/outer diameter of the locking disc 7 and the width of the locking position are qualified, then putting the locking disc pressing component 2 on the main body component 1 to tightly screw a screw rod, and finally operating the locking position height and levelness detection component 6 to check whether the levelness and the height of the locking position of the fuel tank oil pump locking disc are qualified.
In conclusion, the fuel tank oil pump locking disc checking fixture in the embodiment of the utility model can objectively and directly check and display whether the height and the levelness of the locking position of the fuel tank locking disc are qualified or not through the locking position height and levelness detection component 6, so that the problem that the size of the position cannot be measured is solved, and the problems that the checking error of the fuel tank oil pump locking disc is large and misjudgment is easily caused are solved.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the utility model.
