Abstract

The utility model relates to a measuring device for overall length of an axle, comprising a scale body, a sliding scale, a screw and a guide shaft. The measuring device for overall length of an axle is characterized in that the scale body is a long circular steel pipe; a claw is arranged at one end of the scale body; two V-shaped racks are arranged in the middle of the scale body; the guide shaft is connected with the other end of the scale body; the guide shaft is a hollow cylinder shaft; scales are arranged on a circumference face of the guide shaft along the axial direction; an elongated slot is opened on the guide shaft along the axial direction; the sliding scale is composed of a sliding cylinder and the claw; a plane parallel with an axle center surface is prepared at a side of the axle center surface of the sliding cylinder; and the plane is divided into two parts of an upper part and a lower part. Scales are carved on the bottom of the plane; a rectangle aperture is opened on an upper part of the plane; a screwed hole is opened in the middle of the sliding cylinder; and the sliding cylinder is sleeved on the guide shaft. The rectangle aperture is opposite to the scales on the circumference face of the guide shaft; the screw is screwed on the screwed hole; and a tip of the screw is opposite to the elongated slot of the guide shaft. The advantages of the measuring device for overall length of an axle are that: measuring is accurate by using the two V-shaped racks for positioning; and a scale surface is on a horizontal surface and sight line is vertical to the ground when the scale is read, so that detection in rows of a batch of the axles is convenient.

Description

Axletree length overall measurement mechanism

Technical field

The utility model relates to a kind of axletree length overall measurement mechanism, belongs to the measurement mechanism field.

Background technology

Lorry axle is one of vital part of running part, and it is a length greater than 2 meters multidiameter, and tolerance is 1mm, use common kind of calliper, can not guarantee that the slide calliper rule center is parallel with axle center, measurement result is inaccurate, and sight line is parallel to the ground during reading, is not easy to the axletree batch detection; Measure with logical no-go gage, can not reading, give and fill in checking file and reclamation work has brought difficulty.

Summary of the invention

The purpose of this utility model be for accurately, be convenient for measuring a kind of axletree length overall measurement mechanism that axle length provides.

The purpose of this utility model realizes in the following manner:

The utility model comprises blade, slide rule, screw, guide shaft, it is characterized in that: blade is a long round steel pipe, end at blade is provided with claw, the blade middle part is provided with two V-type framves, the other end at blade connects guide shaft, guide shaft is a hollow cylindrical shaft, periphery upper edge at guide shaft is axially arranged with scale, have elongated slot on guide shaft vertically, slide rule is by slide cartridge, claw constitutes, and slide cartridge axle center face one side is made the plane parallel with the axle center face, the plane is divided into, following two parts, scale is carved with in bottom on the plane, has a slot on the top on plane, and the slide cartridge middle part has a threaded hole, slide cartridge is enclosed within on the guide shaft, and slot is facing to the scale on the guide shaft periphery, and screw is screwed on the threaded hole, and the tip of screw is facing to the elongated slot of guide shaft.

The utility model has the advantages that:, measure accurately with two V-type framves location; The scale face is on surface level, and sight line is perpendicular to the ground during reading, and being convenient in batches, axletree in a row detects.
