Problems solved by technology
[0004] Since the outer circle 103 is a curved surface structure, it is impossible to directly measure the axial distance L with a conventional measuring ruler
In the existing technology, it is generally necessary to use a professional profiler to complete the measurement of the axial distance L. The operation of the profiler is complicated and inefficient, and it is difficult to meet the needs of batch measurement

Embodiment Construction
[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] like image 3 As shown, in a specific embodiment, the bevel gear chamfering measuring tool provided by the present invention includes an inner hole measuring piece 1 and an outer circle measuring piece 2 . in:
[0020] The inner hole measuring piece 1 includes a thicker head 11 and a thinner rod 12 axially connected to the lower end of the head 11, the diameter of the rod 12 is slightly smaller than the inner hole of the bevel gear to be measured aperture. The head 11 has a first diameter with a predetermined size, and the first diameter is the inner hole diameter Φd at the predetermined measurement position of the chamfer. The outer circle measuring part 2 includes a body part 21, and a socket hole passing through the b...

The invention provides a bevel gear chamfer measuring tool, which comprises an inner hole measuring member and an excircle measuring member. The inner hole measuring member comprises a coarse head portion and a thin rod portion axially connected to the lower end of the head portion, the diameter of the rod portion matches the aperture of the inner hole of a bevel gear to be measured, the head portion is provided with a predetermined first diameter; the excircle measuring member includes a body portion, a sleeving hole penetrating the body portion is formed in the middle of the body portion, the excircle measuring member is sleeved on the head portion of the inner hole measuring member through the sleeve hole and can slide up and down in the axial direction along the head portion, the peripheral edge of the body portion extends axially downward to form a bent portion perpendicular to the body portion, the body portion is provided with a predetermined second diameter. The bevel gear chamfer measuring tool has the advantages of simple structure and convenient operation, and can realize the rapid measuring of the bevel gear chamfer.
Description
technical field [0001] The invention relates to the field of metal precision forging, in particular to a bevel gear chamfering measuring tool. Background technique [0002] Bevel gear parts are a common automotive component. like figure 1 As shown, it shows the structure of a typical bevel gear part 100, the inside of the bevel gear part 100 is formed with an inner hole 101, and one end of the inner hole 101 is formed with an outwardly expanding chamfer 102, the bevel gear part 100 An outer circle 103 is formed on the outside. [0003] After the bevel gear part 100 is forged and formed, the position of the chamfer 102 needs to be measured and characterized. like figure 2 As shown, the characterization method of the chamfering position is: determine a measurement position on the chamfer 102, define the inner diameter of the measurement position as the inner hole diameter (marked as Фd); determine another measurement position on the outer circle 103, and define the The o...
