Abstract
The utility model discloses a tool for fastening an oil tank opening cover, and aims at providing a tool for fastening an oil tank opening cover with reliable fastening, and the tool is labor-saving when the oil tank opening cover is fastened, and is used for controlling a fastening torque on the oil box opening cover by means of being matched with a pneumatic torque wrench. The tool for fastening the oil tank opening cover comprises a fastening sleeve; a groove matched with a convex rib on the oil tank opening cover is arranged at the lower end of the fastening sleeve; a connection shaft is arranged at the position of a circle center of the upper end of the fastening sleeve; the connection shaft is fixedly arranged on the fastening sleeve through a supporting frame; and an outer hexagonal column is arranged at the upper end of the connection shaft.
Description
Technical field
The utility model relates to a kind of assembly tool in the automobile production manufacture process, especially relates to a kind of frock be used to tightening fuel tank covering cap of automobile.
Background technology
In automobile, fuel tank is requisite key components and parts in the automobile as the container that loads fuel oil.On the reservoir port of automotive oil tank, fuel tank flap is housed usually seals.Therefore fuel tank cap is because its build is larger, and structure is comparatively special, for the fastening comparatively inconvenience of fuel tank flap.
In the actual production assembling process, tighten for the fastening manual methods that is generally of fuel tank flap, namely adopt a kind of easy circular cylinder, it utilizes external structure to block fuel tank flap, pulls a rocking arm with fastening fuel tank flap with hand.Because it is larger that its torsion requires, the workman comparatively requires great effort in installation process, has increased workman's labour intensity, and operating efficiency is also lower, and owing to be manually fastening, the moment of therefore tightening is difficult to guarantee constant, tension between fuel tank flap and fuel tank when moment is excessive, and fuel tank flap damages easily, and moment is when too small, cooperate not closely between fuel tank flap and the fuel tank, fuel tank is poorly sealed, and its security is difficult to be guaranteed.
The utility model content
The utility model be for overcome prior art manually to the fastening labor strength that increased of fuel tank flap, the deficiency that can't control screw-down torque, the comparatively laborsaving while can cooperate pneumatic torque spanner that the screw-down torque of fuel tank flap is controlled when a kind of fastening fuel tank flap was provided, fastening comparatively reliably fuel tank flap fastening device.
To achieve these goals, the utility model is by the following technical solutions:
A kind of fuel tank flap fastening device of the present utility model, comprise fastening sleeve, described fastening sleeve lower end is provided with the groove that can match with the convex tendon on the fuel tank flap, described fastening sleeve upper end home position is provided with connecting axle, described connecting axle is relative with fastening sleeve fixing by bracing frame, and described connecting axle upper end is provided with outer-hexagonal shape cylinder.Fastening sleeve is used for entangling fuel tank flap, and the groove of fastening sleeve lower end can cooperate with the convex tendon on the fuel tank flap.The outer-hexagonal shape cylinder of connecting axle upper end can be used with pneumatic torque spanner.Adopt pneumatic torque spanner, the workman does not need to carry out manually fastening, can significantly reduce workman's labour intensity.When using pneumatic torque spanner to drive connecting axle, by the bracing frame drive fastening sleeve rotation fastening sleeve of connecting axle below, thereby tighten fuel tank flap.Because therefore the size that pneumatic torque spanner can be regulated control moment can guarantee that the moment of fastening fuel tank flap equates, has guaranteed the reliability of installing.
As preferably, be connected with head rod in the middle part of the described connecting axle, described head rod middle part is provided with the second connecting rod of one, and the other end of described head rod and the second connecting rod all forms the arm of stability to the bending of fastening sleeve side.The arm of stability can be clamped the both sides of fuel tank, so that when fastening fuel tank flap, fuel tank can not avoided manually need not to hold the too much manual labor that fuel tank stops its rotation to bring along with fuel tank flap rotates, and has removed extra positioning attaching clamp from yet.
As preferably, be fixed with handle in the middle part of described the second connecting rod.Handle is set is convenient to the installer and locates this frock, when tightening, be convenient to stable to guarantee that fuel tank flap installs smoothly.
As preferably, be provided with some lightening holes in the middle part of the described fastening sleeve.Lightening hole is set has saved material and weight, alleviate the labour intensity of workman in carrying and disassembly process.
As preferably, described fastening sleeve adopts No. 45 steel to make.Adopt No. 45 steel, guarantee that fastening sleeve has higher intensity, simultaneously also comparatively wear-resisting, be convenient to long-term use.
Therefore, the utlity model has following beneficial effect: (1) this frock is fastening by fuel tank flap is carried out, and has reduced workman's labour intensity, can control to guarantee the reliability of installing to the moment of tightening; (2) arm of stability in the frock can be located rapidly fuel tank, has removed detent mechanism etc. from, has reduced production cost.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, the second connecting rod 1, handle 2, bracing frame 3, connecting axle 4, outer-hexagonal shape cylinder 4a, fastening sleeve 5, lightening hole 5a, groove 5b, head rod 6, arm of stability 1a, 6a.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1, a kind of fuel tank flap fastening device comprises fastening sleeve 5, bracing frame 3, connecting axle 4 etc.Fastening sleeve 5 adopts No. 45 steel to make, and its lower end is provided with groove 5b, and fastening sleeve 5 can match with convex tendon on the fuel tank flap by groove 5b, and fastening sleeve 5 middle parts are provided with some lightening hole 5a, have saved material and weight.Connecting axle 4 is relative fixing with fastening sleeve 5 by bracing frame 3, and connecting axle 4 is positioned at fastening sleeve 5 upper end home positions, and connecting axle 4 upper ends are provided with outer-hexagonal shape cylinder 4a, can be connected with pneumatic torque spanner.
Connecting axle 4 middle parts are provided with the head rod 6 of flexible connection, head rod 6 middle parts are provided with the second connecting rod 1 of one, the other end of head rod 6 and the second connecting rod 1 all forms arm of stability 6a, 1a to fastening sleeve 5 side bendings, arm of stability 6a, 1a can position fuel tank when tightening, guarantee the stable of rundown process, and can remove detent mechanism from, reduced cost.The second connecting rod 1 middle part is fixed with handle 2.
During actual the use, groove 5b on the fastening sleeve 5 cooperated with the convex tendon of fuel tank flap be inserted in, simultaneously arm of stability 1a, 6a are stuck in the fuel tank both sides, arm of stability 1a, 6a make fuel tank flap fuel tank when tightening can not occur rotating thereupon, utilize connecting axle 4 upper end outer-hexagonal shape cylinder 4a to cooperate with pneumatic torque spanner, open pneumatic torque spanner behind the setting screw-down torque and tighten.With hand steered firmly handle 2, drive fuel tank flaps by fastening sleeve 5 and rotate when tightening, thus fastening fuel tank flap.
