Abstract
The utility model discloses a sphere distance span quick qualitative measuring appliance combined with gear connection teeth. A measuring appliance body is in a shape of a disk, stepstair-shaped holes are arranged in the measuring appliance body, an inner diameter of a upward large hole is longer than that of a connection teeth addendum circle of a workpiece, and three measuring ends are arranged distributed evenly on an inner wall of the large hole. The measuring ends are radial rectangle rib strips, and the thickness of each measuring end is equal to a setting ball diameter value of the connection teeth. Tops of the measuring ends are in a semi-circle shapes, and a vertical dimensions distance from a centers of each semi-circles to an upper end surfaces of the measuring appliance body is equal to a distance between a setting datum plane of the connection teeth and the measuring position. Circle diameters formed by centers of the three semi-circles are equal to a middle value of a sphere distance span of the workpiece connection teeth. When in detection, the workpiece connection teeth are levelly placed in the measuring appliance body, and the measuring ends are inserted between each two connection teeth, a mismachining tolerance type can be determined according to positions of the workpiece connection teeth under the status. The sphere distance span quick qualitative measuring appliance combined with the gear connection teeth is simple in structure, short in a modeling detection process and high in efficiency, can quickly qualitatively determine the actual quality of the workpiece, and is particularly suitable for a site of a mass production and the field usage.
Description
Technical field
The utility model relates to a kind of check tool for measuring length, and the utility model relates to the appliance special for detecting that a kind of fast qualitative detects combination gear connection tooth sphere distance specifically.
Background technology
Combination gear in the automotive transmission is a kind of doubly-linked gear of unitized construction, and what transmit moment of torsion is helical gears, and the tooth that is connected that overlaps interlocking with tooth is a kind of involute gear that has tapering.Connect tooth and be used for car gear shifting, whether gear shift reliably depends primarily on the transverse tooth thickness that connects tooth.If transverse tooth thickness is not then hung gear greater than difference on the design thickness, transverse tooth thickness is less than the then easy security incident that causes out of supply of design thickness allowance below nominal size.
Connecting tooth is a kind of involute gear with tapering, and profile of tooth is three-dimensional structure, does not have definite value so transverse tooth thickness gradually changes, common with the sphere distance of three-coordinates measuring machine measurement apart from a certain position of reference field, with this covert measuring tooth thickness in the industry.Connect tooth during detection and be shaped, have only by adjusting the transverse tooth thickness that datum-plane position changes the sphere distance place if transverse tooth thickness is overproof.As for the adjusted value of reference field, then calculate definite by the profile of tooth tapering.Prior art can be accomplished accurate measurement in process of production fully, but device for performing measurements costs an arm and a leg, complicated operation, measuring process are long, uses to have certain limitation, is not suitable for detecting in mass production field.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, and propose a kind of production scene that is adapted at and use, and also simple in structure, easy to detect, the combination gear that can objectively respond the actual mass situation connects tooth sphere distance fast qualitative cubing.
The utility model is achieved through the following technical solutions technical goal.
Combination gear connects tooth sphere distance fast qualitative cubing, and its improvements are: establish stepped bore in the cubing body in the form of annular discs, macropore internal diameter up connects tooth tip diameter, 3 measuring junctions of macropore inner wall even distribution greater than workpiece.Described measuring junction is rectangle rib radially, its thickness equals workpiece and connects the amount bulb diameter value of setting between the tooth, the measuring junction top is semicircle shape, the distance of center circle cubing body upper surface vertical dimension of semicircle equals workpiece and connects the distance of tooth setting reference field to the measuring position, and the circular diameter of being made up of the center of circle of 3 semicircles equals to connect tooth sphere distance intermediate value.
Workpiece connects the tooth horizontal and goes in the cubing body of said structure, measuring junction inserts workpiece and connects between the tooth, flush with cubing body upper surface on the plane up if workpiece connects tooth, it is middle poor to show that workpiece connection tooth is in the transverse tooth thickness of setting inspection positions, and quality adheres to specification.Be higher or lower than a certain distance value in cubing body upper surface to show that then workpiece connects tooth super thick or ultra-thin in the transverse tooth thickness of setting inspection positions in the plane up if workpiece connects tooth, need to revise reference field and adjust transverse tooth thickness.
The utility model compared with prior art has following benefit:
1, simple in structure, low cost of manufacture, easily make;
2, medelling detects, and testing process is short, efficient is high, is fit to the production scene and uses;
3, testing result is directly perceived, reduces the technical ability requirement to the operative employee.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Embodiment
Combination gear shown in the drawings connects tooth sphere distance fast qualitative cubing, and its main component cubing body 1 is in the form of annular discs, establishes stepped bore in the cubing body 1, and macropore internal diameter up connects tooth tip diameter, 3 measuring junctions 2 of macropore inner wall even distribution greater than workpiece 3.Described measuring junction 2 is rectangle rib radially, its thickness equals workpiece 3 and connects the amount bulb diameter value of setting between the tooth, measuring junction 2 tops are semicircle shape, the distance of center circle cubing body 1 upper surface vertical dimension of semicircle equals workpiece 3 and connects the distance of tooth setting reference field to the measuring position, and the circular diameter of being made up of the center of circle of 3 semicircles equals to connect tooth sphere distance intermediate value.
During detection, at first workpiece 3 is connected the tooth horizontal and go in the cubing body 1 of said structure, measuring junction 2 inserts workpiece and connects between the teeth, in this state according to the position judgment mismachining tolerance type of workpiece 3.Flush with cubing body 1 upper surface on the plane up if workpiece 3 connects tooth, it is middle poor to show that then workpiece 3 connection teeth are in the transverse tooth thickness of setting inspection positions, and quality adheres to specification.Be higher or lower than a certain distance value in cubing body 1 upper surface in the plane up in case workpiece 3 connects tooth, it is super thick or ultra-thin in the transverse tooth thickness of setting inspection positions to show that then workpiece 3 connects tooth, needs to revise reference field and adjusts transverse tooth thickness, adheres to specification until quality.
The utility model is simple in structure, and the medelling testing process is short, efficient is high, but fast qualitative is judged the actual mass of combination gear connection tooth.
