[0002] In the machining industry, accurate measurement of the angle of the workpiece bevel is one of the difficulties in on-site machining. There are two main methods for current measurement: the first is to use a standard angle comparison block or angle gauge for detection, and a projector for small parts; the second is to send the workpiece to the laboratory for detection using precision instruments.

[0003] However, when using the first method, when comparing and measuring the angle blocks, the angle range is determined by manually visually comparing the gap between the block and the product angle, which has a high risk of misjudgment and low detection efficiency. In addition, there is the problem of inconvenient adjustment of the angle gauge. When using the second method, the projector is only suitable for measuring parts with smaller shapes and is not suitable for the detection of larger products. At the same time, laboratory testing is time-consuming and inefficient, and is not suitable for real-time measurement. Summary of the invention

[0008] Furthermore, in some embodiments of the present application, the detection member is provided with a protrusion, and the protrusion is used to limit the sliding of the detection member.

[0009] Furthermore, in some embodiments of the present application, the detection mechanism further includes a limiting member and an elastic member, the limiting member is clamped in a slide groove provided on the detection member, and the elastic member is sleeved on the detection member.

[0030] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0031] See also Figure 1The embodiment of the present application provides a detection device 100 for detecting the angle of the inclined surface 102 of the product 101. The detection device 100 includes a machine platform 10, a clamping mechanism 20 and a detection mechanism 30. The clamping mechanism 20 and the detection mechanism 30 are arranged on the machine platform 10. The clamping mechanism 20 is used to clamp the product 101 to be detected to prevent the product 101 from shaking during detection. The detection mechanism 30 is used to detect the angle of the inclined surface of the product 101.

[0032] See also Figure 2 The machine 10 includes a main board 11 and a support column 12, and the main board 11 is used to place the product 101. The support column 12 is arranged at the four corners of the main board 11, and is used to support the main board 11 for easy transportation and placement. In one embodiment, the main board 11 includes a mounting portion 111, and the mounting portion 111 is symmetrically arranged at one end of the main board 11, and is used to install the clamping mechanism 20 and the detection mechanism 30. In one embodiment, the main board 11 is generally in the shape of a "concave" character.

[0033] The machine 10 further includes a positioning member 13, which is disposed on the main board 11 and is used to cooperate with the clamping mechanism 20 to fix the product 101 to be tested on the main board 11 to achieve positioning of the product 101 to be tested. In one embodiment, the number of the positioning members 13 is three.

[0034] The clamping mechanism 20 is used to clamp the product 101 to be tested to fit the mainboard 11. In one embodiment, the clamping mechanism 20 is a toggle clamp 21, which is used to fix the product 101 on the mainboard 11 under the action of tightening. The toggle clamp 21 is provided with a support seat 211, and the support seat 211 is fixed on the mounting portion 111. In one embodiment, the number of the toggle clamps 21 is two, which are symmetrically arranged on the mounting portion 111 and used in combination to make the force on the product 101 more uniform. It can be understood that the clamping mechanism 20 can be other mechanisms as long as it satisfies the requirement of fixing the product 101 on the mainboard 11.

[0035] See also Figure 3, the detection mechanism 30 includes a positioning block 31, a fixed block 32, a support member 33, an abutment member 34 and a detection member 35. The positioning block 31 and the fixed block 32 are fixedly mounted on the mounting portion 111. One end of the support member 33 is connected to the positioning block 31, and the other end abuts against the abutment member 34. The abutment member 34 is limitedly arranged on the fixed block 32. The detection member 35 is slidingly limitedly arranged on the support member 33 for detecting the inclined surface 102 of the product 101. In one embodiment, the positioning block 31 and the fixed block 32 are fixedly connected to the mounting portion 111 by bolts. It can be understood that the number of the support member 33 and the abutment member 34 is not limited, and can be two, three, four or other numbers. In one embodiment, the number of the detection mechanism 30 is two, and they are symmetrically arranged on the mounting portion 111 to make the detection more accurate.

[0036] Furthermore, the positioning block 31 includes a beveled surface 311, and the beveled surface 311 is used to cooperate with the support member 33 to detect the product 101, while preventing contact with the beveled surface 102 of the product 101 during detection, thereby affecting the detection.

[0037] The fixing block 32 is fixedly disposed at one end of the positioning block 31 away from the chamfered surface 311, and is used to fix the abutment member 34. In one embodiment, the fixing block 32 is a rectangular parallelepiped structure.

[0038] The support member 33 includes a first support member 331 and a second support member 332. The first support member 331 includes a first insertion portion 3311 and a first protrusion 3312. The first insertion portion 3311 is connected to the first protrusion 3312, and the first insertion portion 3311 is inserted into the positioning block 31. The first protrusion 3312 protrudes out of the positioning block 31. The first protrusion 3312 is also provided with a first through hole 3312a, and the first through hole 3312a is used to install the detection member 35.

[0039] It can be understood that the second support member 332 is generally similar to the first support member 331 in structure. Specifically, the second support member 332 includes a second insertion portion 3321 and a second protrusion 3322, and the second protrusion 3322 protrudes from the positioning block 31. In one embodiment, one end of the first insertion portion 3311 and the second insertion portion 3321 are set in an arc shape to prevent scratching the product 101 when contacting the product 101 to be tested. During testing, the end of the first insertion portion 3311 away from the first protrusion 3312 and the end of the second insertion portion 3321 away from the second protrusion 3322 are tangent to the product 101 to make the test result more accurate. In one embodiment, the first support member 331 and the second support member 332 are pins.

[0040] The abutment member 34 includes a first abutment member 341 and a second abutment member 342, and the first abutment member 341 and the second abutment member 342 are slidably disposed on the fixed block 32 to respectively push the first support member 331 and the second support member 332 to move. Specifically, an elastic member 343 is sleeved on one end of the first abutment member 341 so that the first abutment member 341 is elastically connected to the fixed block 32. A limiting member 344 is disposed at the other end, and the limiting member 344 is clamped on the annular groove 3411 provided on the first abutment member 341 to limit the movement of the first abutment member 341. In one embodiment, the elastic member 343 is a compression spring, and the limiting member 344 is generally "C"-shaped.

[0041] It can be understood that the second abutting member 342 is substantially similar to the first abutting member 341 in structure, and will not be described in detail again. In one embodiment, the first abutting member 341 and the second abutting member 342 are pins.

[0042] The detection member 35 is slidably disposed on the first protrusion 3312, and the structure of the detection member 35 is substantially similar to that of the first abutment member 341. Specifically, the detection member 35 further includes a limiter 351 and an elastic member 352. The limiter 351 is clamped on the annular groove 3511 provided on the detection member 35 to limit the movement of the elastic member 352. The elastic member 352 is sleeved on one end of the detection member 35 close to the annular groove 3511 to enable the detection member 35 to be elastically connected to the first protrusion 3312.

[0043] The detection member 35 is further provided with a protrusion 354 at one end away from the annular groove 3511, and the protrusion 354 is used for limiting and preventing the detection member 35 from being separated from the first protrusion 3312. By pressing the detection member 35, the protrusion 354 abuts against the second protrusion 3322. In one embodiment, the elastic member 352 is a compression spring.

[0044] See also Figure 4 and Figure 5, since the cross section of the first support member 331 and the second support member 332 in contact with the product 101 is an arc shape, during measurement, the inclined surface 102 of the product 101 is tangent to the surface of the first support member 331 and the second support member 332, and the cross section of the shape formed by the extension line of the inclined surface 102, the sliding direction of the second support member 332 and the extension line of the detection member 35 form a right triangle, and correspond to the hypotenuse c, right angle side a and right angle side b of the right triangle respectively. As the tolerance allowed for the inclined surface angle changes to θ, the length of the right angle side a where the detection member 35 is located does not change, the hypotenuse c where the inclined surface 102 of the product 101 is located changes from hypotenuse c1 to c2, and the length of the right angle side b changes from b1 to b2, so that the difference between b2 and b1 can be used to determine whether the angle change range of the inclined surface 102 is within the allowable range. It can be understood that when the detection member 35 is set, the distance between the protrusion 354 and the end of the detection member 35 away from the limiting member 351 is set to the difference between b2 and b1 to determine whether the angle is in compliance.

[0045] When the detection device 100 detects a product, the product 101 is first attached to the main board 11, and the product 101 is positioned by the positioning member 13, and then the product is fixed on the main board 11 by the clamping mechanism 20. Then, the inclined surface 102 after the rotating shaft of the product 101 is unfolded is brought into contact with the first support member 331 and the second support member 332, so as to push the first support member 331 and the second support member 332 to slide, and the elastic member 343 is compressed. The detection member 35 is pressed, and the detection member 35 has a certain displacement. When the protrusion 354 of the detection member 35 abuts against the second protrusion 3322 of the second support member 332, the product 101 meets the requirements and is a qualified product; when the protrusion 354 of the detection member 35 does not contact the second support member 332, the product 101 does not meet the requirements and is a defective product.

[0046] The above detection device has a simple structure and utilizes the right triangle principle to convert the change of the inclined plane angle into a linear dimension, which greatly improves the detection accuracy and reduces the difficulty of manual operation.

[0047] The above embodiments are only used to illustrate the technical solutions of the embodiments of the present application and are not intended to limit them. Although the embodiments of the present application are described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the embodiments of the present application.
