Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of testing tools, and particularly relates to a filter shell mounting hole positioning testing tool. BACKGROUND

[0002] The application field of filters is extremely wide, including vehicle and engine filtration, industrial dust, welding fume and oil mist filtration, compressed air filtration and process filtration and the like. In the above-mentioned fields, the shell of the filter is generally regular in shape and is convenient to install, but some filters are custom products, the shell of which is irregular, and the position precision of the mounting holes on the shell is high. Figure 4 As shown in the figure, the bottom surface and the side surface of the shell of the filter are provided with a plurality of mounting holes, and the shape and size of the mounting holes have extremely high requirements. However, due to the irregular shape, the detection error of the conventional testing tool is large, and the detection precision of the three-coordinate measuring instrument is high, but the detection efficiency is slowed down.

[0009] The utility model positions the lower part of the filter shell through the positioning piles, and positions the upper part of the filter shell through the quick clamp, when the position of the filter shell is determined, the detection piles and the detection pins correspond to the mounting holes of the filter shell, and whether the shape and size of the mounting holes on the filter shell are qualified can be quickly judged by observing whether the detection piles and the detection pins are inserted into the mounting holes of the filter shell.

[0010] Further, the positioning surface of the plurality of positioning piles is inclined at the upper part and vertical at the lower part.

[0011] The beneficial effect of the step is that the inclined surface has a guiding effect, guiding the filter shell to be embedded between the plurality of positioning piles, and the vertical surface is a positioning surface, which can limit the position of the filter shell.

[0014] Further, the plurality of detection piles include at least one reference detection pile.

[0015] The top of each detection pile is provided with a positioning pin.

[0016] The diameter of the positioning pin of the reference detection pile is larger than that of the positioning pin of the other detection piles.

[0017] The beneficial effect of the step is that the size difference between the reference detection pile and the other detection piles is the same as the design tolerance.

[0018] Further, the movable frame is connected to the base plate through a pair of parallel sliding rails.

[0022] Further, the detection pin is provided with a spring.

[0023] The beneficial effect of the step is that the detection pin is movable, and the detection pin is kept in an extended state under the action of the spring; when the detection pin contacts the filter shell and is aligned with the mounting hole, the detection pin is inserted into the mounting hole; when the detection pin is not aligned with the mounting hole, the detection pin is retracted under the action of the filter shell.

[0024] The beneficial effect of the utility model is that:

[0025] The application can replace conventional gauges and high-precision gauges such as three-coordinate measuring instruments, guide the filter shell into the detection position through the positioning piles, and quickly and accurately detect the mounting hole of the filter shell through the detection piles on the base plate and the detection pins on the movable frame.

[0042] a base plate 1;

[0043] a plurality of positioning piles 2, a plurality of positioning piles 2 are annularly arranged on the surface of the base plate 1, the positioning pile 2 is matched with the filter housing, and can guide the filter housing into the detection position;

[0044] A plurality of detection stakes 3 are arranged in the annular positioning stake 2;

[0045] A movable frame 4 is arranged on the base plate 1 and located on one side of the positioning stake 2, the top end of the movable frame 4 is provided with a quick clamp 41, the front end of the quick clamp 41 is provided with a clamp capable of clamping the top of the filter housing, and one side of the movable frame 4 relative to the positioning stake 2 is provided with a plurality of detection pins 42.

[0046] The utility model discloses a positioning stake 2 positions the lower part of the filter housing, and then a quick clamp 41 positions the upper part of the filter housing, when the position of the filter housing is determined, the detection stake 3 and the detection pin 42 will correspond to the mounting hole of the filter housing, and by observing whether the detection stake 3 and the detection pin 42 are inserted into the mounting hole of the filter housing, the mounting hole size of the filter housing can be quickly judged.

[0047] On the basis of the above technical scheme, the positioning surface of the plurality of positioning stakes 2 is inclined at the upper part and vertical at the lower part.

[0048] The inclined surface has a guiding effect and guides the filter housing to be embedded between the plurality of positioning stakes 2, and the vertical surface is a positioning surface and can limit the position of the filter housing.

[0049] On the basis of the above technical scheme, at least one of the positioning stakes 2 is conical at the upper part and cylindrical at the lower part.

[0050] The conical surface has a multidirectional guiding effect relative to the inclined surface, the cylindrical surface is in linear contact with the filter housing, cooperates with other surface contact, has a certain movement space, and prevents the filter housing from being stuck between the plurality of positioning stakes 2 during placement.

[0054] In the application, the mounting holes of the filter are all M10 threaded holes, but when the shape and position dimensions of the mounting holes are detected, the threaded holes have not been processed, and the mounting holes are still light holes at this time; therefore, the diameter of the positioning pin of the reference detection stake is φ8mm, and the diameter of the positioning pin 31 of the other detection stakes 3 is φ6.9mm; the size difference between the reference detection stake and the other detection stakes 3 is the same as the design tolerance.

[0057] The base plate 1 is further provided with at least one positioning clamping groove 5, which is matched with the rotating pin 43.

[0058] Since the movable frame 4 can move forward and backward through the slide rails 6, when the detection pin 42 of the movable frame 4 detects the mounting hole on the side surface of the filter shell, the movable frame 4 is maintained at the detection position through the positioning clamping groove 43.
