Description

Technical Field

[0001] This invention relates to the field of rapid inspection of the interface dimensions of shaft housings, and specifically to an inspection device and method for housing parts. Background Technology

[0002] Currently, most of the housings and enclosures of servo mechanisms produced are shaft-type parts. During the inspection process, the interface dimensions of these parts are mostly measured using a five-axis coordinate measuring machine. For parts with larger outer diameters, an inner diameter caliper and an outer diameter micrometer are used to measure the diameter. Since the housing usually has holes, the position and angle of the circumferential holes are measured using a coordinate measuring machine. This results in a long time required for measurement preparation and programming, and the time required for each measurement is long, leading to low efficiency in the inspection process.

[0029] This embodiment discloses a device for inspecting housing parts, such as... Figure 1 , Figure 3 As shown, it may include:

[0030] The system includes a positioning module 10 and multiple detection units, with the positioning module 10 and the multiple detection units connected through each other. The positioning module 10 includes a first positioning part 11 and multiple first positioning holes 13, each of which is disposed through the peripheral wall of the first positioning part 11. Each of the detection units is movably connected to the positioning module 10 through the first positioning hole 13.

[0031] The housing 30 has a plurality of first detection holes 33 provided on its peripheral wall;

[0032] The housing 30 part detection device has a first working state and a second working state; the first working state includes: when the housing 30 is sleeved with the positioning module 10, each of the detection units can be connected through the first positioning hole 13 and each of the first detection holes 33;

[0033] The second working state includes: when the housing 30 is sleeved with the positioning module 10, at least one of the detection units cannot be connected through the first positioning hole 13 and the first detection hole 33.

[0034] In this embodiment, by placing the housing 30 inside the positioning module 10, adjusting the first detection hole 33 to a preset position, and connecting the detection unit through the first positioning hole 13 and the first detection hole 33; among them, if all the detection units are connected to the first detection hole 33, the quality of the housing 30 is qualified; otherwise, the quality of the housing 30 is unqualified; thus, the position accuracy and angle of the circumferential holes can be detected quickly, greatly improving the detection efficiency. In this embodiment, the housing 30 is located inside the positioning module 10 and is spaced from the positioning module 10, and the spacing distance can be set as needed. In this embodiment, a partition board is further provided at one end of the first positioning portion 11, and the partition board is fixedly connected to the first positioning portion 11.

[0035] In some embodiments, such as Figure 2 , Figure 3 As shown, the positioning module 10 further includes a second positioning portion 12 and a plurality of second positioning holes 14, one end of the second positioning portion 12 is fixedly connected to one end of the first positioning portion 11; the inner surface of the second positioning portion 12 is equidistant from the inner surface of the first positioning portion 11; the inner cavity volume of the second positioning portion 12 is smaller than the inner cavity volume of the first positioning portion 11; the second positioning holes 14 penetrate through the circumferential wall of the second positioning portion 12; the detection unit includes a first detection module 20, and the first detection module 20 includes a first detection portion 21 and a second detection portion 22; one end of the second detection portion 22 is fixedly connected to one end of the first detection portion 21, and the second detection portion 22 can be connected through the second positioning hole 14.

[0036] In this embodiment, the positioning module 10 further includes a second positioning portion 12 and a plurality of second positioning holes 14, and the detection unit includes a first detection module 20. The first detection module 20 includes a first detection portion 21 and a second detection portion 22; one end of the second detection portion 22 is fixedly connected to one end of the first detection portion 21, and the second detection portion 22 can be connected through the second positioning hole 14, so that the detection unit can detect housings 30 of different sizes, improving the function of this detection tooling.

[0037] In some embodiments, such as Figure 3As shown, the detection unit further includes a first baffle plate 23, which is fixedly disposed between the first detection part 21 and the second detection part 22.

[0038] In this embodiment, by setting a baffle plate, the baffle plate can limit the first detection part 21 inserted into the first positioning hole 13 and limit the second detection part 22 inserted into the second positioning hole 14, thereby avoiding the situation where the first detection part 21 and the second detection part 22 are inserted too deeply or not deeply enough, resulting in inaccurate detection.

[0039] In some embodiments, such as Figure 4 , Figure 5 As shown, the detection unit includes a second detection module 40, which includes a spring piece 41, a connecting part 42, a connecting rope 43, a sliding rod 44, and a locking block 45. There are multiple spring pieces 41. One end of two adjacent spring pieces 41 is fixedly disposed on the connecting part 42 at equal intervals, and the other end is fixedly connected to one end of the connecting rope 43. The other end of the connecting rope 43 is fixedly connected to one end of the sliding rod 44. The end of the spring piece 41 away from the connecting part 42 is equidistant from the sliding rod 44. A through hole is provided on the connecting part 42, and the central axis of the through hole is collinear with the central axis of the sliding rod 44. The sliding rod 44 is movably connected to the connecting part 42 through the through hole. The locking block 45 is fixedly connected to the end of the spring piece 41 away from the connecting part 42. The locking block 45 has a groove for engaging the first detection hole 33. A scale is provided on the sliding rod 44, and the scale is evenly distributed along the axial direction of the sliding rod 44.

[0040] In this embodiment, the groove shape on the locking block 45 of the second detection module 40 can be configured to engage with the first detection hole 33. The spring pieces 41 are arranged in a circumferential array on the connecting part 42. The second detection module 40 is used as follows: when detecting the first detection hole 33, the slide bar 44 is pulled to bring the ends of the spring pieces 41 away from the connecting part 42 closer together. Then, the spring pieces 41 are inserted into the first detection hole 33, causing the slot on the locking block 45 to engage with the first detection hole 33. The scale on the slide bar 44 is recorded. Based on the expansion of the spring pieces 41 and the retraction of the slide bar 44, a corresponding scale value is set on the slide bar 44. This scale value corresponds to the size of the expansion of the spring pieces 41, thereby allowing the measurement of the size of the corresponding first detection hole 33. In this embodiment, the positioning module 10 can be made of transparent glass, facilitating observation and operation, and the slide bar 44 and the connecting rope 43 are in a taut state.

[0041] In some embodiments, the cross-sectional shape of the groove is an isosceles trapezoid, and the bottom surface of the groove corresponding to the least base of the isosceles trapezoid is an arc surface, which can be interference-fitted with a portion of the housing 30 at the first detection hole 33.

[0042] In this embodiment, by setting the cross-section of the groove to be equal to the shape of a trapezoid, it is possible to quickly and easily allow the arc surface to be interference-fitted with a portion of the housing 30 at the first detection hole 33, thereby accelerating the detection rate.

[0043] In some embodiments, the connecting portion 42 is cone-shaped, the perforation is located at the center of the largest end of the cone, and the smallest end of the cone is fixedly connected to the spring piece 41.

[0044] In this embodiment, by setting the connecting part 42 as a conical shape and fixing the smallest end to the spring piece 41, the conical connecting part 42 has a certain taper, so that when the connecting part 42 is inserted into the first detection hole 33, the central axis of the connecting part 42 can be on the same straight line as the central axis of the first positioning hole 13, making it less likely for the spring piece 41 to deviate.

[0045] In some embodiments, the second detection module 40 further includes a second baffle 46; the second baffle 46 is fixedly connected to the end of the connecting portion 42 away from the spring piece 41.

[0046] In this embodiment, by providing a second baffle 46, it is easy to remove the connecting part 42 from the first positioning hole 13.

[0047] In some embodiments, the second detection module 40 further includes a third baffle plate 47; the third baffle plate 47 is fixedly connected to one end of the slide rod 44 away from the connecting rope 43, and the connecting part 42 is located between the connecting rope 43 and the third baffle plate 47.

[0048] In this embodiment, the included angle between the first positioning hole 13 or the second positioning hole 14 is a known included angle.

[0049] This embodiment discloses that the second detection module 40 further includes a fourth partition plate 48 and a spring 49. The fourth partition plate 48 is fixedly connected to the slide rod 44. The fourth partition plate 48 is located between the third partition plate 47 and the connecting part 42. The spring 49 passes through the slide rod 44. One end of the spring 49 abuts against the connecting part 42, and the other end abuts against the fourth partition plate 48.

[0050] In this embodiment, by setting a spring 49, the slide rod 44 is tightened by the elastic force of the spring 49, so that the scale value at the end face of the connecting part 42 can be read quickly, and then the aperture of the first detection hole 33 can be obtained.

[0051] This embodiment also discloses a method for inspecting housing parts, including the following steps:

[0052] Step S11: Based on the fact that the housing 30 is located inside the positioning module 10, adjust the first detection hole 33 to a preset position;

[0053] Step S12: Based on the first detection hole 33 being aligned with the first positioning hole 13, the detection unit is connected to the first detection hole 33 through the first positioning hole 13; wherein, if all the detection units are connected to the first detection hole 33, the housing 30 is of qualified quality; otherwise, the housing 30 is of unqualified quality.

[0054] In this embodiment, the housing is located inside the positioning module, the first detection hole is adjusted to a preset position, and the detection unit is connected to the first detection hole through the first positioning hole; if all detection units are connected to the first detection hole, the housing quality is qualified; otherwise, the housing quality is unqualified; thereby quickly detecting the position and angle of the circumferential hole, greatly improving the detection efficiency.

[0055] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this disclosure.
