Abstract
The utility model discloses a gauge for measuring the distance between a center line of a boss of a crank case and an arc-shaped working surface. The gauge comprises a location guide rod, a measurement sleeve, a measurement column, a fastening screw and a handle, wherein the end part, which is connected with the center hole of the boss of the crank box, of the location guide rod is provided with a threaded rod, the rest part of the location guide rod is provided with a smooth rod, the measurement sleeve is sleeved on the smooth rod, and can slide or rotate relative to the smooth rod, the measurement sleeve is provided with a measurement hole along the radial direction, the measurement column is in clearance fit with one end of the measurement hole, the measurement column is provided with a measurement head which outwards protrudes from the measurement hole and acts with the arc-shaped working surface, the fastening screw is inserted in the measurement sleeve along the axial direction of the measurement sleeve, the end part, which is provided with a thread, of the fastening screw is matched with the measurement column, and the handle is connected with the end part, which is far away from the boss of the crank case, of the location guide rod. The gauge can be used for conveniently and efficiently measuring the position size of the boss in batches.
Description
Technical field
A kind of automobile component measurer of the utility model, be specifically related to a kind of crankcase boss center line to the circular arc workplace apart from gauge.
Background technology
Automobile engine crankshaft case boss portion bit position size (being that the boss center line is to circular arc workplace distance) for the batch Mechanized Processing is measured, and adopts artificial no gauge rough measure mode now always, and inspects by random samples by the material object comparison.There is following defective in this mode: 1) can not adapt to the measurement one by one of producing line high frequency time beat in enormous quantities; 2) production quality control there is to a certain degree influence; 3) overall process of measuring is very inconvenient; 4) the product Measuring Time is longer; 5) measured product size precision is low and will leave production line.
Summary of the invention
The purpose of the utility model provide a kind of crankcase boss center line to the circular arc workplace apart from gauge, with convenient, efficient and boss portion bit position size is measured in batches.
The described a kind of crankcase boss center line of the utility model to the circular arc workplace apart from gauge; Comprise positioning and guiding bar, measuring unit, measurement column, holding screw and handle, the end that said positioning and guiding bar is connected with crankcase boss center pit is a threaded rod, and remainder is a smooth shaft; Said measuring unit is set on the said smooth shaft; And but the relative light slide bar slides or rotation, and measuring unit radially is provided with measured hole, and said measurement column clearance fit is at an end (being convenient to adjust tolerance) of measured hole; Measurement column have outside measured hole protrusion and with the gauge head of circular arc workplace effect; Said holding screw axially interts on measuring unit along measuring unit, and its end with screw thread cooperates with measurement column, and said handle is connected with the end of positioning and guiding bar away from the crankcase boss.Location, guiding when the positioning and guiding bar is used to measure, measuring unit and measurement column are used for distance, and whether satisfactory measurement judges that holding screw is used to adjust the tolerance of measurement column.
Further, more firm for handle is connected with the positioning and guiding bar, said handle and positioning and guiding bar are located by connecting through round pin.
Be drilled with center pit on the crankcase boss of motor car engine, the center pit inside fire attack has internal thread, and the boss workplace is an arc-shaped surface; When using gauge to measure; Earlier the threaded rod with the positioning and guiding bar screws in the crankcase boss center pit, up to threaded rod revolve motionless till, rotation or slip measuring unit then; If the gauge head of measurement column can screw in or slip in the circular arc workplace smoothly; Then this boss position position dimension is qualified, if the gauge head of measurement column can not screw in smoothly or slip in the circular arc workplace, and this boss position position dimension defective (being crankcase boss center line to the circular arc workplace) then apart from short.
The utility model is compared with prior art and had the following advantages: after 1) using this gauge, the detection frequency and the measuring speed of production in enormous quantities are very fast; 2) this gauge is more convenient more flexible than existing measuring operation, but on-line measurement; 3) this gauge is more faster, more directly perceived than existing measurement to measure analog data perception degree, just knows whether qualified three seconds; 4) problem that the data that the first line measurement is come out according to produced on-site occur in time analyzing and researching and processing; 5) use this gauge can spot-check product to be processed at any time, monitoring forefront of the production product quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Crankcase boss center line as shown in Figure 1 apart from gauge, comprises positioning and guiding bar 1, measuring unit 2, measurement column 3, holding screw 4 and handle 6 to the circular arc workplace, and the end that positioning and guiding bar 1 is connected with crankcase boss center pit is a threaded rod; Remainder is a smooth shaft; Measuring unit 2 is set on the smooth shaft, but and the relative light slide bar slides or rotation, measuring unit 2 radially is provided with measured hole 21; Measurement column 3 clearance fit are at an end of measured hole 21; Measurement column 3 have outside measured hole 21 protrusion and with the gauge head 31 of circular arc workplace effect, holding screw 4 axially interts on the end of measuring unit 2 away from the crankcase boss along measuring unit 2, the end that holding screw 4 has screw thread cooperates with measurement column 3; Be used to adjust tolerance, handle 6 is connected with the end of positioning and guiding bar 1 away from the crankcase boss through round pin 5.
Be drilled with center pit on the crankcase boss 7 of motor car engine, the center pit inside fire attack has internal thread, and the boss workplace is an arc-shaped surface; When using gauge to measure; Earlier the threaded rod with positioning and guiding bar 1 screws in the crankcase boss center pit, up to threaded rod revolve motionless till, rotation or slip measuring unit 2 then; Measuring unit 2 drives measurement column 3 rotations or slides; If the gauge head 31 of measurement column 3 can screw in smoothly or slip in the circular arc workplace 8, then this boss position position dimension is qualified, if the gauge head 31 of measurement column 3 can not screw in or slip in the circular arc workplace 8 smoothly; This boss position position dimension defective (center line that is crankcase boss 7 is short to the distance of circular arc workplace 8, does not meet the demands) then.
