Description

Technical Field

[0001] The utility model relates to the field of flatness detection, in particular to a flatness detection device for parts production. Background Art

[0002] Flatness is a type of geometric tolerance, which refers to the deviation of the macroscopic concave and convex height of the surface of an object from the ideal plane. In traditional detection methods, flatness measurement usually includes: feeler gauge measurement method, liquid level method, laser plane interferometer measurement method, level meter / digital level measurement method, and meter measurement method. After the parts are produced, the flatness of their surfaces needs to be tested. For example, metal plate parts, after various forming processes, will be prepared into thin sheet parts of a certain shape and thickness according to needs. After being prepared into thin sheet parts, the plate surface stress will change due to the thinning of the plate surface thickness, and the plate may also warp and deform, which may seriously affect the appearance or assembly performance of the parts. Therefore, the flatness of the thin sheet parts needs to be tested.

[0003] When the existing flatness detection device is detecting, since the thin sheet parts are relatively light, the parts to be detected may shake due to external vibrations, resulting in inaccurate detection data, thereby reducing the qualified rate of the product and affecting production costs.

[0004] Therefore, we made improvements to this and proposed a flatness detection device for parts production. Utility Model Content

[0033] like Figure 1-6 As shown, this embodiment proposes a flatness detection device for part production, including a detection platform 1, a support plate 2 and a detection box 3. The support plate 2 is fixedly installed on the top right side of the detection platform 1. The detection box 3 is slidably connected to the support plate 2. A pressure sensor 4 is arranged in the detection box 3. The bottom of the pressure sensor 4 is electrically connected to a pressure sensing column 5. The detection box 3 drives the pressure sensing column 5 to move downward, so that the pressure sensing column 5 contacts the part to be detected, and the pressure sensing column 5 contacts one end of the part and applies pressure to it. The pressure is transmitted to the pressure sensor through the pressure sensing column 5. On the sensor 4, a first U-shaped frame 6 is fixedly installed on the detection table 1, a threaded rod 7 is rotatably connected to the first U-shaped frame 6, an L-shaped clamping plate 8 is threadedly connected to the threaded rod 7, a driving component is arranged on the threaded rod 7, and an auxiliary component is arranged at the bottom of the detection table 1. When detecting, a flatness detection device for parts production in the present application not only has accurate detection results, but also can support lighter thin parts to avoid shaking of thin parts due to external vibrations, resulting in inaccurate detection data, thereby reducing the qualified rate of the product and affecting the production cost.

[0034] In order to clamp the two L-shaped clamps 8 at the same time, the driving assembly includes a first gear 9 fixedly mounted on the threaded rod 7, the first gear 9 is meshedly connected to the second gear 13, the second gear 13 is meshedly connected to the third gear 14, and the end of the threaded rod 7 away from the first U-shaped frame 6 is fixedly connected to a hand wheel 10, the hand wheel 10 drives the threaded rod 7 to rotate, and the rotation of the threaded rod 7 causes the L-shaped clamp 8 to move downward, and at the same time, the threaded rod 7 drives the first gear 9 to rotate, the first gear 9 drives the second gear 13 to rotate, the second gear 13 drives the third gear 14 to rotate, and the third gear 14 drives the threaded rod 7 at the other end to rotate, so that rotating one hand wheel 10 can drive the two L-shaped clamps 8 to move downward to clamp the parts, thereby improving work efficiency and facilitating operation.

[0035] In order to cooperate with the movement of the L-shaped clamping plate 8, the auxiliary component package is fixedly installed on the second U-shaped frame 11 at the bottom of the detection table 1, and sliding rods 12 are fixedly installed on both ends of the second U-shaped frame 11. The end of the sliding rod 12 away from the second U-shaped frame 11 is fixedly connected to the first U-shaped frame 6. The sliding rod 12 is slidably connected to the L-shaped clamping plate 8. The threaded rod 7 rotates to move the L-shaped clamping plate 8 downward, and the L-shaped clamping plate 8 moves along the sliding rod 12 at the same time.

[0036] In order to cooperate with the up and down movement of the detection box 3, sliding grooves 17 are opened on both side walls of the support plate 2, and a slider 18 is fixedly installed on the right side of the detection box 3. The slider 18 cooperates with the sliding groove 17, and the detection box 3 drives the slider 18 to slide downward along the sliding groove 17.

[0038] In order to support the second gear 13 , a rotating shaft 15 is fixedly connected to the second gear 13 , and one end of the rotating shaft 15 away from the second gear 13 is connected to a bearing at the bottom of the detection platform 1 .

[0039] In order not to affect the up and down movement of the L-shaped clamping plate 8 , a through slot 19 is provided on the testing platform 1 , and the through slot 19 matches with the L-shaped clamping plate 8 .

[0040] Specifically, when the flatness detection device for parts production is used: the parts to be detected are placed on the detection table 1, and then the hand wheel 10 is turned, the hand wheel 10 drives the threaded rod 7 to rotate, the threaded rod 7 rotates to make the L-shaped clamping plate 8 move downward, and the L-shaped clamping plate 8 moves along the slide rod 12 at the same time, and the threaded rod 7 drives the first gear 9 to rotate, the first gear 9 drives the second gear 13 to rotate, the second gear 13 drives the third gear 14 to rotate, and the third gear 14 drives the threaded rod 7 at the other end to rotate, so that the two L-shaped clamping plates 8 can be driven to move downward to clamp the parts by turning one hand wheel 10, which improves work efficiency and is easy to operate. When facing lighter thin parts, they can be supported to avoid shaking of the thin parts due to external vibration, resulting in inaccurate detection data;

[0041] After clamping, the electric push rod 20 is started through the switch, and the output end of the electric push rod 20 drives the detection box 3 to move downward, and the detection box 3 drives the slider 18 to slide downward along the slide groove 17, and the detection box 3 drives the pressure sensing column 5 to move downward, so that the pressure sensing column 5 contacts the part to be detected, and the pressure sensing column 5 contacts one end of the part and applies pressure to it.
