Description

Technical Field

[0001] This utility model relates to the field of component testing technology, specifically a precision component testing fixture. Background Technology

[0002] A component refers to an indivisible individual part in machinery. It is a basic component of a machine and a fundamental unit in the mechanical manufacturing process, and its manufacturing generally does not require assembly. However, in actual use, it still has some drawbacks. For example, existing precision component appearance inspection fixtures have the problem of inaccurate inspection results. When the object being inspected is placed on the worktable without being fixed, any movement of the fixture will affect the signal detected by the inspection device, thus affecting the inspection results.

[0003] A precision parts appearance inspection fixture with application number 202020328139.X includes a worktable. Through the cooperation of a first sleeve rod, a return spring, a second sleeve rod, and a fixing clamp, accurate inspection results are achieved. This avoids the problems of existing precision parts appearance inspection fixtures where the inspected object is placed on the worktable without being fixed. If the device moves, the detection signal is affected, thus affecting the inspection results. Furthermore, inaccurate inspection results can lead to mismatches between the used parts and the specified part models, hindering development. This fixture enhances practicality. However, it is not convenient for clamping and fixing curved parts, nor is it convenient for rotating and flipping fixed parts for inspection. Utility Model Content

[0004] The purpose of this utility model is to provide a precision component inspection fixture to solve the problems in the prior art of not being able to clamp and fix arc-shaped components, and not being able to rotate and flip the fixed components for inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision parts inspection fixture, comprising a base, an upright plate on the upper side of one end of the base, a first slider on one side of the upright plate via a first lead screw, a transverse support plate on one side of the first slider, a second slider on the lower side of the transverse support plate via a second lead screw, a visual inspection camera rotatably mounted on the lower side of the second slider via a connecting seat and a connecting shaft, a first motor being driven to one end of the connecting shaft via a first gear set, a fixed support plate and a movable support plate on the upper side of the base, a positioning clamp being rotatably mounted on one upper side of both the fixed support plate and the movable support plate via a support shaft, and a second motor being driven to one end of the support shaft via a second gear set.

[0006] Furthermore, the first lead screw is a Z-axis lead screw, and the second lead screw is an X-axis lead screw.

[0007] Furthermore, both the first gear set and the second gear set are reduction gears, the first motor is fixedly mounted on the outer wall of the connecting seat, and the second motor is fixedly mounted on the side wall of the fixed support plate.

[0008] Furthermore, the support shaft is vertically rotatably mounted to one side of the fixed support plate and the movable support plate via bearings, and the two support shafts are mounted on the same axis.

[0009] Furthermore, the positioning clamp is an arc-shaped clamp, and the inner wall of the positioning clamp is provided with a protective pad.

[0010] Furthermore, the lower end of the movable support plate is slidably connected to the limiting groove on the upper side of one end of the base via a third slider, and a cylinder is provided on one side of the third slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has a fixed support plate, a movable support plate, a support shaft and a positioning clamp on the upper side of the base, so that one positioning clamp is driven by a cylinder to move to the side of another positioning clamp, which facilitates the clamping and fixing of the arc-shaped parts.

[0013] 2. In this utility model, a visual inspection camera is rotatably mounted on the lower side of the second slider via a connecting seat and a connecting shaft. One end of the connecting shaft is connected to a first motor via a first gear set. This allows the connecting shaft to be rotated in both directions by the first motor and the first gear set, thereby adjusting the tilt angle of the visual inspection camera and satisfying the requirements for photographing and inspecting at different longitudinal angles.

[0014] 3. In this utility model, both the fixed support plate and the movable support plate have a positioning clamp on one side of the upper end via a support shaft. A second motor is connected to one end of the support shaft via a second gear set. This allows the support shaft to be rotated in both directions by the second motor and the second gear set, thereby enabling longitudinal rotation adjustment of the parts fixed between the two positioning clamps. This eliminates the need for manual flipping and allows for visual inspection of parts at different angles, greatly improving the efficiency of parts inspection. Attached Figure Description

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the utility model, a precision component inspection fixture includes a base 1, an upright plate 2 on the upper side of one end of the base 1, a first slider 3 on one side of the upright plate 2 via a first lead screw 4, a transverse support plate 5 on one side of the first slider 3, a second slider 19 on the lower side of the transverse support plate 5 via a second lead screw 6, and a vision inspection camera 9 rotatably mounted on the lower side of the second slider 19 via a connecting seat 8 and a connecting shaft 20 for taking pictures of the components. The picture information is transmitted to a controller, which processes the pictures and compares them with pre-stored qualified appearance pictures to achieve visual inspection of the component appearance. The first lead screw 4 is a Z-axis lead screw, and the second lead screw 6 is an X-axis lead screw. The first lead screw 4 and the second lead screw 6 are used to drive the vision inspection camera 9 to move and adjust, thereby performing visual appearance inspection of the components. The inspection effect is high, and the operation is convenient and fast.

[0022] like Figure 1 and Figure 3As shown, in order to meet the requirements of different longitudinal angles for image capture and detection, a first motor 21 is also connected to one end of the connecting shaft 20 through a first gear set 22. This allows the connecting shaft 20 to be rotated in both directions by the first motor 21 and the first gear set 22, thereby adjusting the tilt angle of the visual inspection camera 9 and meeting the requirements of different longitudinal angles for image capture and detection.

[0023] like Figure 1 and Figure 2 As shown, in order to improve the stability of clamping and fixing parts, a fixed support plate 10 and a movable support plate 11 are provided on the upper side of the base 1. The lower end of the movable support plate 11 is slidably set with the limiting slide groove 7 on the upper side of one end of the base 1 through the third slider 12, and a cylinder 13 is provided on one side of the third slider 12. The upper side of both the fixed support plate 10 and the movable support plate 11 is rotatably provided with a positioning clamp 16 through the support shaft 15. The support shaft 15 is rotatably set perpendicularly to one side of the fixed support plate 10 and the movable support plate 11 through the bearing 14, and the two support shafts 15 are set on the same axis, so that the cylinder 13 drives one positioning clamp 16 to move to the other positioning clamp 16 side, which is convenient for clamping and fixing the arc-shaped parts. The positioning clamp 16 is an arc-shaped clamp, and the inner wall of the positioning clamp 16 is provided with a protective pad, which increases the anti-slip property of the inner wall of the positioning clamp 16 and facilitates the improvement of the stability of clamping and fixing parts.

[0024] like Figure 1 and Figure 2 As shown, in order to meet the visual inspection needs of parts at different angles, a second motor 18 is also connected to one end of the support shaft 15 via a second gear set 17. Both the first gear set 22 and the second gear set 17 are reduction gears. The first motor 21 is fixedly installed on the outer wall of the connecting seat 8, and the second motor 18 is fixedly installed on the side wall of the fixed support plate 10. This allows the support shaft 15 to be rotated in both directions by the second motor 18 and the second gear set 17, thereby enabling longitudinal rotation adjustment of the parts fixed between the two positioning clamps 16. This eliminates the need for manual flipping and allows for visual inspection of parts at different angles, greatly improving the efficiency of parts inspection.

[0025] The working principle and usage process of this utility model are as follows: When in use, the part to be inspected is placed between two positioning clamps 16.
