Abstract
The utility model relates to a special measuring tool for measuring coaxiality of a short shaft hole and an outer hole wall of a crankshaft, which comprises a hole rod and a measuring tool body. The hole rod and the measuring tool body are separated, the measuring tool body is sleeve-shaped, a coaxial stepped hole are arranged in the measuring tool body, the outer end hole of the stepped hole is matched with the outer wall of the short shaft hole of the crankshaft, and the inner end hole of the stepped hole is matched with the hole rod. The special measuring tool has a simple structure and a reasonable design, is easy to operate, can achieve accurate measurement, and can significantly improve the efficiency in detection of the coaxiality of the short shaft hole and the outer hole wall of the crankshaft. Compared with the traditional measuring way, the detection efficiency can be increased by more than five times. Therefore, the special measuring tool effectively improves the production efficiency and also the production quality.
Description
Technical field
The utility model relates to the cubing of field of machining, particularly a kind of bent axle minor axis hole and hole outer wall coaxality measurement appliance special for detecting.
Background technology
Being shaped on diameter on PL/BD type bent axle is the minor axis hole of φ 8, and the outer diameter in this hole is φ 12.5, owing to need to guarantee the minor axis hole of bent axle and the right alignment between this hole outer wall, therefore need detect its right alignment.Existing detection mode exists measures difficult, deficiencies such as measurement is inaccurate, complex operation, the time is long, efficient is low, influences the production efficiency and the quality of production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple to operate, measure bent axle minor axis hole and hole outer wall coaxality measurement appliance special for detecting accurately.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of bent axle minor axis hole and hole outer wall coaxality measurement appliance special for detecting, it is characterized in that: constitute by separate hole rod and cubing main body, the cubing main body is a sleeve shaped, in the cubing main body, be shaped on coaxial shoulder hole, the outer stomidium of this shoulder hole and bent axle minor axis hole outer wall coupling, stomidium and hole rod coupling in this shoulder hole.
Advantage of the present utility model and beneficial effect are:
The utility model is simple in structure, reasonable in design, easy and simple to handle, measurement is accurate, can significantly improve detection efficiency to bent axle minor axis hole and hole outer wall right alignment, improve more than 5 times than the traditional measurement mode, thereby effectively enhance productivity, improve the quality of production simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model (operation chart).
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of bent axle minor axis hole and hole outer wall coaxality measurement appliance special for detecting, its innovation part is: be made of separate hole rod 2 and cubing main body 1, the cubing main body is a sleeve shaped, in the cubing main body, be shaped on coaxial shoulder hole, minor axis hole 3 outer walls made on the outer stomidium of this shoulder hole and the bent axle 4 mate, stomidium and hole rod coupling in this shoulder hole.
Use-pattern of the present utility model is:
The diameter that during measurement the hole rod is threaded onto on the bent axle is in the minor axis hole of φ 8, the cubing main body is set on this hole rod, the interior stomidium of cubing main body and hole rod coupling, the outer end borehole jack of cubing main body is loaded on the outer wall of hole, if the cubing main body can smooth and easy rotation, determine that promptly the bent axle diameter is that the minor axis hole of φ 8 and hole wall right alignment that diameter is φ 12.5 are qualified.
