Abstract
The invention discloses a fast qualitative checking fixture for the over-ball distance of a connecting gear of a combination gear, which is provided with a checking fixture body in a disc shape. A stepped hole is reserved in the disc-shaped checking fixture body, the inner diameter of an upward large hole is larger than the diameter of an addendum circle of workpiece connecting teeth, three measuring ends are evenly distributed on the inner wall of the large hole, each measuring end is a radial rectangular rib, the thickness of each radial rectangular rib is equal to a valve of the ball diameter between the workpiece connecting teeth, the top of each measuring end is semicircular, a vertical distance from a circle center of the semicircle to the upper end face of the checking fixture body is equal to a distance from a connecting tooth set reference plane to a measurement position, and the diameter of a circle formed by the circle centers of the three semicircles is equal to a mid-value of over-ball distances of the workpiece connecting teeth. During measurement, the workpiece connecting teeth are placed flat in the checking fixture body, the measuring ends are inserted into the work connecting teeth, and machining error types are determined according to the positions of the workpiece connecting teeth. The fast qualitative checking fixture is simple in structure, short and efficient in modular detection, capable of rapidly and qualitatively determining actual quality of a workpiece, and particularly suitable for a site in batch production.
Description
Technical field
The present invention relates to a kind of check tool for measuring length, the present invention relates to a kind of fast qualitative specifically and detect the appliance special for detecting that combination gear connects the tooth sphere distance.
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 then is prone to the security incident that causes out of supply less than the 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, and measures the sphere distance apart from a certain position of reference field with three-coordinates measuring machine usually in the industry, with this covert measuring tooth thickness.Connect tooth during detection and be shaped, have only through 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.
Summary of the invention
The present invention is primarily aimed at the deficiency of 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 present invention realizes technical goal through following technical proposals.
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.Said 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 that tooth is set reference field to 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 ultra 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 present invention compared with prior art has following benefit:
1, simple in structure, low cost of manufacture, be prone to 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 an embodiment of the invention structural representation.
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.Said 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 that tooth is set reference field to 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 ultra 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 present invention 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.
