Description
Technical field
The utility model belongs to drill bit detection field, and in particular to one kind is used for brake drum product processing bolt hole
Drill bit the sharpening drill bit test measuring device of detection is carried out after sharpening.
Background technique
At this stage, the outward flange bottom surface of every product of automobile brake drum need to process the bolt hole of 8-10 different dimensions
It is assembled.Currently, frequently with processing method are as follows: drilled using upright drill, using common high-speed steel fiber crops when drilling
Flower drill bit carries out repeating to sharpen using.Drill bit after sharpening requires two main cutting edges of drill bit symmetrical and equal length, and
It is required that the apex angle of drill bit is symmetrical after sharpening.But in actual bolt hole process, due to the detection of drill bit after shortage sharpening
Measurer often results in sharpening main cutting edge asymmetry, and length is unequal, and the bolt hole bored inclination easy to form influences
The assembly precision of brake drum product；And often bored bolt hole is caused to cut not because of drill head apical angle asymmetry after sharpening
Uniformly, bit wear is fast, and then it is bigger than normal to influence bored bolt hole aperture, while also shortening the service life of drill bit, mentions
High production cost.
Summary of the invention
In consideration of it, the purpose of the utility model is to provide a kind of sharpening drill bit test measuring devices, it is intended to overcome current braking
The defect that drill bit is detected after drum product lacks during processing bolt hole to sharpening.
In order to reach above-mentioned purpose of utility model, and then the technical solution taken is as follows:
A kind of sharpening drill bit test measuring device, including drill bushing, drill bushing frame and drill bit detect pedestal, the top peace of the drill bushing frame
Lower part equipped with the drill bushing, drill bushing frame is equipped with the drill bit detection pedestal, and the drill bushing, drill bushing frame and drill bit detect bottom
The center of seat keeps coaxial, in addition, a through-hole is offered in the center of the drill bushing, in drill bit detection pedestal
Heart position offers a V-shaped groove, and the V-arrangement angle of the V-shaped groove is 118 °, the V-arrangement angle with through its drill bushing through-hole and stretching
The drill bit to be measured entered to V-shaped groove is in contact, and the apex angle and cutting edge length of the drill bit to be measured are detected with this.
It further, is to be flexibly connected between the drill bushing frame and drill bit detection pedestal.
Further, drill bushing frame lower part has a groove, and the top of the drill bit detection pedestal has a boss, institute
It states boss to match with the groove, be flexibly connected between the drill bushing frame and drill bit detection pedestal with realizing.
The utility model has the beneficial effects that the sharpening drill bit test measuring device of the utility model can rapidly to sharpening after
Drill bit is detected, at the same can also intuitively detect sharpening after drill bit apex angle and cutting edge length it is whether symmetrical, detected
Journey is simple, and detection efficiency is high.Using the drill bit after this test measuring device detection sharpening, the bolt hole aperture bored and position degree are full
Sufficient customer requirement, improves product quality；And it is symmetrical using the main cutting edge of the sharpening drill bit after the detection of this test measuring device,
Uniform force in the cutting process that drills, and then the service life of drill bit is improved, reduce production cost.
