Description
Technical field
The utility model relates to a kind of cubing, especially relates to a kind of cubing of heat shield of fuel tank.
Background technology
Heat shield of fuel tank is usually located between gas outlet and the fuel tank, reduces the impact that waste-gas heat causes fuel tank in the gas outlet.Chinese patent Granted publication number: CN 201472149U discloses a kind of Novel energy-saving oil tank, bottom in the fuel tank is provided with the layered thermal insulation plate parallel with the fuel tank bottom that tilts, the inclination bottom of described layered thermal insulation plate is provided with breach, described layered thermal insulation plate is divided into the two-layer up and down of connection with the inner chamber of fuel tank, the bottom of the inclination of the fuel tank corresponding with above-mentioned breach is provided with a stillpot, lateral wall at stillpot is provided with magnet, be provided with successively alternating current-direct current double-purpose electric heating preheating zone and tail gas heating district along the acclivitous fuel tank of stillpot bottom, the inclining of described heating demarcation strip cut the top and is provided with an exhaust pin hole, described fuel oil efferent duct passes fuel tank outer wall and layered thermal insulation plate and is communicated with inclined upper at fuel tank bottom compartment, be provided with oil jug and fuel oil return pipe in the top inner chamber of fuel tank, the breach that the layered thermal insulation plate is passed in the bottom of set thermometer in the fuel tank extend in the fuel tank bottom compartment.Thermal insulation board wherein is provided with a plurality of mounting hole site, the detection of these mounting hole site is manually to utilize vernier caliper or tape measure to detect, because the thermal insulation board profile has radian, detect larger apart from the size time error between the position, two holes, occur easily that mounting hole on the thermal insulation board deviation occurs with spiro keyhole position on the fuel tank, the problem such as can't align.
The utility model content
The utility model is in order to overcome the larger deficiency of manual detection heat shield of fuel tank time error in the prior art, a kind of heat shield of fuel tank cubing of energy Effective Raise heat shield of fuel tank accuracy of detection to be provided.
To achieve these goals, the utility model is by the following technical solutions:
The cubing of a kind of heat shield of fuel tank of the present utility model comprises monitor station and four test pins, and described monitor station is provided with the pilot hole that is complementary with test pin, and the axis of described test pin is perpendicular to the upper surface of monitor station.Test pin is positioned on the monitor station, and four test pins are four mounting hole site on the corresponding heat shield of fuel tank respectively, detect between the mounting hole apart from size.When manual employing vernier caliper or tape measure are measured, can only detect the diameter of mounting hole, the home position of mounting hole is difficult to be determined, range observation error between hole and the hole is very large, and whether spatially relative position relation meets designing requirement and also be difficult to check by the metering system of such routine between the mounting hole.And by this cubing, only need produced heat shield of fuel tank is placed on the cubing, can detect on the thermal insulation board whether to meet production requirement apart from size and position relationship between the mounting hole, the accuracy of testing result improves greatly.Avoided the heavy work of repeatedly measuring for detecting the workman, testing process is comparatively quick, has improved detection efficiency.
As preferably, the shank that described test pin comprises cylinder and is positioned at the cylinder end face, described cylinder end face is parallel to the upper surface of monitor station.Whether the plane at cylinder end face place can meet production requirement for detection of the position of the countersunk head plane in the vertical direction around the mounting hole on the thermal insulation board as the locating surface of shank, thereby assurance thermal insulation board energy is smooth and fuel tank is fixed.
As preferably, described monitor station is orthogonal, and described test pin is distributed in the corner location of monitor station.Such four test pins are four mounting hole site of corresponding workpiece respectively, and take full advantage of the space of monitor station, the making material consumption of farthest having saved monitor station.
As preferably, described test pin and monitor station welding.After the welding of test pin and monitor station, test pin can not come off with monitor station, guarantee simultaneously prolonged and repeated use after, test pin can not become flexible and affect the accuracy of detection.
As preferably, the axial width of described shank is 10 ~ 20mm, and the diameter of described shank is 8mm.The diameter of shank matches with the thermal insulation board mounting hole, when detecting, shank penetrates in the mounting hole of thermal insulation board, if four shanks all can pass through on the thermal insulation board separately corresponding mounting hole smoothly, the size that then shows this thermal insulation board is qualified, can carry out follow-up assembling, if could not need do over again or scrap processing.
As preferably, the end face of described cylinder is the disc of diameter 20 ~ 30mm.Countersunk head plane contact around column diameter and the thermal insulation board mounting hole, the diameter of disc is consistent with the diameter on this countersunk head plane.Whether meet the requirements thereby reach detection countersunk head planimetric position, the assurance thermal insulation board can be installed smoothly.
As preferably, the thickness of described monitor station is 5 ~ 30mm.The thickness of monitor station is moderate, is convenient to the testing staff and takes and use, and guarantees simultaneously the rigidity of monitor station, avoids occurring deformation.
Therefore, the utlity model has following beneficial effect: only need workpiece for measurement is placed on directly whether can know workpiece for measurement on the cubing qualified, when guaranteeing higher accuracy of detection, testing process is also comparatively convenient.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, monitor station 1, test pin 2, shank 2a, cylinder 2b.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment as shown in Figure 1, a kind of cubing of heat shield of fuel tank comprises monitor station 1 and four test pins 2, and test pin comprises cylinder 2b and shank 2a, and cylinder and shank are cylindrical, and shank is positioned at the cylinder end face, and the cylinder end face is parallel to the upper surface of monitor station.Four corners of monitor station are respectively equipped with pilot hole, are complementary with the cylinder of test pin, and cylinder bottom and monitor station welding, guarantee that test pin and monitor station are reliably fixing.The axis of cylinder and shank is perpendicular to the upper surface of monitor station.The diameter of shank is 8mm, and axial width is 15mm.Cylinder is cylindrical, and diameter is 25mm, and the diameter of end face is also consistent.The thickness of monitor station is 10mm.
When testing, take out this cubing, four test pins up, place in the plane, fetch afterwards thermal insulation board and place it on this cubing, if four shanks of observation can both pass mounting hole separately smoothly, and end face and the mounting hole countersunk head plane on every side of cylinder fit simultaneously, show that then this thermal insulation board is qualified, can carry out follow-up assembling; If thermal insulation board for reaching testing requirement, then needs to do over again to reaching requirement, perhaps scrap processing, thereby avoid defective workpiece to flow in the follow-up assembling process.
