Description

Technical Field

[0001] The invention relates to the technical field of roughness detection equipment, and in particular to a surface roughness detection equipment applied to a circular connector shell. Background Art

[0002] In the automobile engine system, the circular connector housing plays a vital role. As a key device that wraps and protects the electronic circuit connection components inside the engine, it is usually carefully crafted from high-strength, corrosion-resistant metal materials and presents a compact circular design. In the production process of the circular connector housing for automobile engines, its surface must be strictly tested for roughness. This step is to ensure that the roughness of the housing surface is within a reasonable range of design requirements to meet the needs of close fit with other components to ensure the normal operation of the engine electronic system.

[0003] When performing surface roughness detection of circular connector shells, methods that use optical principles to measure surface roughness are usually involved, such as interference method, speckle method or reflection method, etc. This requires selecting a suitable optical probe or profile measuring instrument based on the material, surface characteristics and roughness requirements of the circular connector shell. Current manual detection uses a handheld optical probe to perform a circular scan of the inner and outer circles of the workpiece, which has significant defects: it is difficult to maintain a constant gap between the probe and the workpiece surface during manual rotation (in order to ensure non-contact detection), which causes the measurement data to be distorted due to distance fluctuations. At the same time, manual positioning can easily lead to accidental collision between the probe and the workpiece, which not only damages the high-precision optical probe, but also scratches the workpiece surface due to impact, further affecting product quality and detection reliability. Based on this, the present invention purposely provides a surface roughness detection device for circular connector shells that can automatically maintain a constant non-contact distance between the probe and the workpiece surface.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 6 As shown, the present invention is a device for detecting the surface roughness of a circular connector housing, comprising: A base 1, on which a three-claw turntable 2 is rotatably mounted, the three-claw turntable 2 is driven to rotate by a first driving source built into the base 1, three circumferentially arranged inner abutting rods 5 are slidably mounted on the three-claw turntable 2, and the three inner abutting rods 5 move synchronously along the radial direction of the three-claw turntable 2, a bearing plate 101 is fixedly mounted on the base 1, an outer ring turntable 3 is rotatably mounted on the bearing plate 101, the outer ring turntable 3 is driven to rotate by a second driving source built into the bearing plate 101, three circumferentially arranged outer abutting rods 6 are slidably mounted in the outer ring turntable 3, and the three outer abutting rods 6 move synchronously along the radial direction of the outer ring turntable 3, the three outer abutting rods 6 are driven to move synchronously by a driving assembly, the outer ring turntable 3 is coaxially arranged with the three-claw turntable 2, a second laser assembly 601 is fixedly mounted on the top of an outer abutting rod 6, and a first laser assembly 501 is fixedly mounted on the top of an inner abutting rod 5; A positioning component, wherein the positioning component is arranged on the base 1; Workpiece 4 is placed on the base 1. When the three inner abutment rods 5 are synchronously expanded, the three inner abutment rods 5 are all abutted against the inner ring of the workpiece 4, so that the workpiece 4 is coaxial with the three-claw turntable 2. When the three outer abutment rods 6 are synchronously retracted, the three outer abutment rods 6 are all abutted against the outer ring of the workpiece 4, so that the workpiece 4 is coaxial with the outer ring turntable 3. At this time, the distance between the first laser component 501 and the inner ring of the workpiece 4 is the same as the distance between the second laser component 601 and the outer ring of the workpiece 4. At the same time, the positioning component records the positions of the first laser component 501 and the second laser component 601 as the first point position and the second point position, respectively.

[0020] The optical measuring needle assembly 10 is connected to the positioning assembly. When the three inner abutment rods 5 are all in abutment with the inner circle of the workpiece 4, the three outer abutment rods 6 expand outwards. At this time, the positioning assembly guides the optical measuring needle assembly 10 to move to the second point position. When the three outer abutment rods 6 are all in abutment with the outer circle of the workpiece 4, the three inner abutment rods 5 retract inwards. At this time, the positioning assembly guides the optical measuring needle assembly 10 to move to the first point position.

[0021] Wherein, a calibration component 22 is disposed on the base 1 , and the calibration component 22 is used for pre-detecting the optical probe component 10 .

[0022] In one case of this embodiment, the calibration component 22 can be a standard roughness template, the first driving source can be a servo motor, a servo motor and other components, the second driving source can be a motor-driven pulley assembly, a motor-driven gear transmission assembly, and other mechanisms that can achieve rotational motion can also be selected. This embodiment is not specifically limited here; it should be noted that the three-claw turntable 2 described in the present invention is a prior art, except that the claws are replaced with internal abutment rods 5 in order to avoid the claws abutting against the workpiece 4 and causing surface damage. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0023] The working principle of the present invention: First, place the workpiece 4 on the base 1. Then, the three-claw turntable 2 controls the three inner abutment rods 5 to expand outward synchronously until the three inner abutment rods 5 are tightly abutted against the inner circle of the workpiece 4 at the same time, thereby achieving coaxial positioning of the workpiece 4 and the three-claw turntable 2. At the same time, the three outer abutment rods 6 inside the outer circle turntable 3 are synchronously retracted inward so that the three outer abutment rods 6 are abutted against the outer circle of the workpiece 4 at the same time, as shown in Figure 3. At this time, the first laser component 501 and the second laser component 601 are both tightly close to the workpiece 4. The positioning component will record the positions of the first laser component 501 and the second laser component 601 as the first point position and the second point position, respectively. These two points are the pre-set positions where the optical probe assembly 10 should be placed, and the preparations before detection are completed; When inspecting the roughness of the inner ring of the workpiece 4: first ensure that the three outer abutment rods 6 continuously abut against the outer ring of the workpiece 4. At this time, the outer ring turntable 3 can be regarded as firmly clamping the workpiece 4 through the outer abutment rods 6. Then, control the three inner abutment rods 5 to retract inward so that they gradually move away from the inner ring of the workpiece 4. Then, move the optical probe assembly 10 toward the first point and approach the workpiece 4 until the working end of the optical probe assembly 10 reaches the position of the first laser assembly 501. Then, with the help of the second driving source, the outer ring turntable 3 is driven to rotate a full circle, thereby driving the workpiece 4 to rotate a circle. In this process, the optical probe assembly 10 can measure the roughness of the workpiece 4. The inner circle is roughened for one circle; when the outer circle roughness of the workpiece 4 is detected: the first step is to move the optical measuring needle assembly 10 to the second point, and at the same time ensure that the three inner abutting rods 5 abut the inner circle of the workpiece 4, and the workpiece 4 is firmly fixed on the three-jaw turntable 2 by this tensioning method, and then the three outer abutting rods 6 are controlled to expand outward to keep away from the workpiece 4, and then the optical measuring needle assembly 10 is moved along the second point close to the outer side of the workpiece 4, and finally, the three-jaw turntable 2 is driven to rotate for one circle by the first driving source, and the workpiece 4 is driven to rotate for one circle together, so that the optical measuring needle assembly 10 can perform roughness detection on the outer circle of the workpiece 4; In this way, the workpiece 4 is first reliably clamped and fixed by the inner abutment rod 5 and the outer abutment rod 6, and then the placement position of the optical probe assembly 10 is marked in advance by the first laser assembly 501 and the second laser assembly 601, and accurately recorded by the positioning assembly, so that the optical probe assembly 10 can accurately reach the preset position when approaching the workpiece 4 for inspection. More importantly, the optical probe assembly 10 only needs to be positioned to the pre-calibrated point once and remains stationary during subsequent inspections. The full-circle scan is completed by the rotation of the workpiece 4 itself, which fundamentally eliminates the risk of gap fluctuation and trajectory deviation caused by the movement of the optical probe assembly 10, improves the speed of positioning the optical probe assembly 10, and ensures that the distance between the optical probe assembly 10 and the workpiece 4 is constant.

[0026] In actual application of this embodiment, after the inner abutment rod 5 and the outer abutment rod 6 clamp the workpiece 4, the first laser assembly 501 and the second laser assembly 601 will emit lasers, and then move through the first positioning plate 14 and the second positioning plate 15, and then the first positioning plate 14 receives the irradiation of the second laser assembly 601, and the second positioning plate 15 receives the irradiation of the first laser assembly 501, so that the second positioning plate 15 and the first positioning plate 14 can be quickly positioned to the first point position and the second point position, and this process can be observed manually, and then the optical measuring needle assembly 10 can be moved to the second point position through the first positioning plate 14 and to the first point position through the second positioning plate 15 through the guide assembly.

[0027] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the positioning component also includes a first receiving hole 1401 and a second receiving hole 1501, the first receiving hole 1401 is arranged on the first positioning plate 14, and the second receiving hole 1501 is arranged on the second positioning plate 15, the first receiving hole 1401, the second receiving hole 1501, the first laser assembly 501 and the second laser assembly 601 are all located in the same plane, and the first receiving hole 1401 and the second receiving hole 1501 are respectively used to receive the irradiation of the second laser assembly 601 and the first laser assembly 501.

[0028] In actual application, this embodiment can automatically determine whether the laser irradiation of the second laser component 601 and the first laser component 501 is received during the movement of the first positioning plate 14 and the second positioning plate 15 through the first receiving hole 1401 and the second receiving hole 1501. In this way, no manual observation is required, and fully automatic operation is achieved, making the positioning of the first positioning plate 14 and the second positioning plate 15 more accurate and rapid.

[0030] In one case of this embodiment, the fifth driving source may be a component or other mechanism capable of realizing linear reciprocating motion, which is not specifically limited in this embodiment.

[0031] In practical application, if Figure 1 As shown in the figure, at this time, the first positioning plate 14 and the second positioning plate 15 have determined the second point and the first point, and then the sliding plate 13 is driven to move by the fifth driving source, so that the sliding connection between the square bar 11 and the first positioning plate 14 moves to the second point, and the sliding connection between the square bar 11 and the second positioning plate 15 moves to the first point. Figure 5 As shown, by lowering the square bar 11 on the first positioning plate 14, the optical probe assembly 10 can be moved to the detection point close to the outer circle of the workpiece 4, and by lowering the square bar 11 on the second positioning plate 15, the optical probe assembly 10 can be moved to the detection point close to the inner circle of the workpiece 4. In this way, by sliding the square bar 11 and the first positioning plate 14, and sliding the square bar 11 and the second positioning plate 15, the square bar 11 can be raised and lowered along a determined trajectory to avoid shaking left and right, thereby avoiding the problem of dynamic changes in the gap between the optical probe assembly 10 and the workpiece 4.

[0033] In actual application of this embodiment, when the inner abutment rod 5 abuts against the inner ring of the workpiece 4, that is, the workpiece 4 is driven to rotate by the rotation of the three-claw turntable 2, the square bar 11 slides down from the first positioning plate 14, allowing the optical probe assembly 10 to approach the outer ring of the workpiece 4, thereby performing roughness detection on the outer ring; similarly, when the square bar 11 slides down from the second positioning plate 15, the optical probe assembly 10 approaches the inner ring of the workpiece 4, thereby performing roughness detection on the inner ring.

[0034] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, a transverse track plate 7 is fixedly installed on the base 1, a longitudinal track plate 8 is slidably installed on the transverse track plate 7, and the longitudinal track plate 8 is driven to move by a sixth driving source built into the transverse track plate 7, an L-shaped slide plate 9 is slidably installed on the longitudinal track plate 8, and the L-shaped slide plate 9 is driven to rise and fall by a seventh driving source built into the longitudinal track plate 8, and the L-shaped slide plate 9 is fixedly connected to the top of the square bar 11, at this time, the optical probe assembly 10, the second laser assembly 601 and the first laser assembly 501 are all located in the same plane.

[0035] In one case of this embodiment, the sixth driving source and the seventh driving source can both be electric cylinders, electric telescopic rods, electric slide rail assemblies and other components, and other mechanisms capable of achieving linear reciprocating motion can also be selected, which is not specifically limited in this embodiment.

[0037] like Figure 1-Figure 6As shown, as a preferred embodiment of the present invention, the driving component includes a slide groove 16, a waist-shaped groove 17, a long rod 18, a round rod 19, a rotating disk 20 and an inclined groove 21. The slide groove 16 and the waist-shaped groove 17 are both opened on the outer abutment rod 6, and the slide groove 16 is connected with the waist-shaped groove 17. The long rod 18 is slidably installed in the slide groove 16, and the outer abutment rod 6 is fixedly installed on one end of the long rod 18. The rotating disk 20 is rotatably installed in the outer ring turntable 3, and the rotating disk 20 is driven to rotate by the output component built into the outer ring turntable 3. The inclined groove 21 is opened on the rotating disk 20, and the inclined groove 21 is inclined, and the inclined groove 21 corresponds to the waist-shaped groove 17. The round rod 19 is slidably installed in the waist-shaped groove 17, the round rod 19 is fixedly connected to the long rod 18, and the round rod 19 is slidably installed in the inclined groove 21.

[0038] In one case of this embodiment, the output assembly may be a motor-driven pulley assembly, a motor-driven gear transmission assembly, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0040] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, when the rotating disk 20 rotates to make the three long rods 18 retract synchronously, the outer abutment rod 6 will move above the three-claw turntable 2. When the three long rods 18 retract, the outer abutment rod 6 is moved to the three-claw turntable 2. This means that the workpiece 4 with a smaller radius can be clamped. Even if the radius of the workpiece 4 does not exceed that of the three-claw turntable 2, the outer abutment rod 6 can abut against the outer circle of the workpiece 4, thereby improving the applicability of the entire device.

[0041] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
