Problems solved by technology

[0002] Twist drill is a commonly used tool in machining, and it is also a kind of fragile tool. It needs repeated grinding during use. The quality of the drill directly affects the quality of drilling and drilling efficiency, and also affects the life of the twist drill. , In order to check whether the lengths of the two main cutting edges of the twist drill are equal and whether the angles of the two main cutting edges are equal during manual grinding, it is necessary to visually measure the length and angle of one main cutting edge from the front, and then visually measure the other main cutting edge after turning 180 degrees. The length and angle of the edge are compared repeatedly, because this comparison has time and space intervals, it is difficult to ensure the accuracy of this method, even if it is measured with a caliper, because there is no reliable card point, the measurement accuracy of the length of the main cutting edge also difficult to grasp
When grinding with a grinding machine, the ordinary grinding machine only ensures that the grinding angle is suitable, but does not guarantee that the lengths of the two main cutting edges are equal. The patent application "a twist drill detection device" provides an intuitive detection of the twist drill main The device for the length and angle of the cutting edge, but in the detection process of the device, if it is necessary to compare the angle between the two main cutting edges with a given angle, or when the angle between the two main cutting edges and the central plane is equal , but also to further determine the value of the included angle of the two main cutting edges, then another angle ruler is needed to measure

Embodiment 1

[0035] Such as figure 2 , 3 , Shown in 4 and 5, a kind of twist drill detection device with angle scale, including main board 101, V-shaped groove 102, sliding groove 103, front rotating shaft 104 and front rotating shaft cap 105;

[0036] The rear end of the main board 101 is an arc-shaped structure, the upper surface of the arc-shaped structure is provided with an angle scale 163, a V-shaped groove 102 is fixed on the main board 101, and is used to place the twist drill 1 to be tested. The front end of the main board 101 has a front shaft 104 , the front shaft 104 is fixedly installed on the main board 101, and is perpendicular to the upper surface of the main board 101, the top of the front shaft 104 has a front shaft cap 105, and the tail of the main board 101 has a sliding groove 103. The plane formed by the center is the central plane of the detection device, which is denoted as the central plane. The V-shaped groove 102 is symmetrical with respect to the central plane...

Embodiment 2

[0044] Such as figure 2 , 7 As shown, in embodiment 1, the angle indicated by the marking line 162 is the angle between the side armor 125 and the center plane, so the angle between the main cutting edge and the central axis of the twist drill 1 is measured, but usually The angle of the twist drill 1 refers to the angle between the two main cutting edges of the twist drill 1. Considering this, the angle between the side armor and the center plane is equal to that between the slide plate 139 and the center plane. You can change the value 40 to 90 in the scale 163 to the value 80 to 180 in the scale 163. At this time, the angle value indicated by the marking line 162 is the angle between the side armor 125 and the skateboard 138. When the twist drill is 1, the degree read is the angle between the two main cutting edges.

[0045] The folded edge 124 of the long arm first 120 is perpendicular to the upper surface of the long arm first 120, and the length of the folded edge 124 ...

Abstract

The invention belongs to the technical field of machining detection tools, and relates to a twist drill detection device with angle scales and a detection method. The detection device comprises a mainboard, a V-shaped groove, a lower sliding groove, a front rotating shaft and a front rotating shaft cap. The tail end of the main board is of an arc-shaped structure. Angle scales are arranged on theupper surface of the arc-shaped structure; a V-shaped groove is fixed on the main plate, and is used for placing a detected twist drill. The front rotating shaft is disposed at the front end of the main board, and the front rotating shaft is fixedly mounted on the main board; the front rotating shaft cap is arranged at the top end of the front rotating shaft, the lower sliding groove is formed inthe tail portion of the main board, a plane formed by the axis of the front rotating shaft and the center of the lower sliding groove is the center plane of the detection device and is recorded as the center plane, the V-shaped groove is symmetrical relative to the center plane, and the lower sliding groove is also symmetrical relative to the center plane. The device can achieve the detection ofthe twist drill simply and conveniently, and is universal; the length of the twist detected drill does not need to be worried about, and an additional bevel protractor does not need to be used.
