Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically to a drilling precision positioning device with adjustable camera angle. Background Technology

[0002] Currently, drilling equipment primarily relies on manual adjustment for drilling positioning. The operation involves manually marking the drilling points on the product, and then manually moving these points to the correct position largely depends on visual judgment. This method is not only time-consuming and labor-intensive for high-precision drilling but can also lead to errors. Therefore, camera-assisted drilling positioning is often added. However, when using camera-assisted drilling positioning, different products require different drilling locations. For example, drilling on concave, convex, or inclined surfaces, or using drill bits of different lengths, all require adjusting the camera angle, making precise drilling positioning difficult.

[0003] Now, a novel drilling precision positioning device with adjustable camera angle is proposed to address the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a drilling precision positioning device with adjustable camera angle to solve the problem of inconvenience in precise positioning of drill holes mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling precision positioning device with adjustable camera angle, comprising a fixed base, a servo cylinder mounted on the right side of the fixed base, a slide table slidably mounted on the right side of the servo cylinder, a camera base fixedly mounted on the bottom of the front end of the slide table, and a camera adjustment frame welded and fixed to the front end of the camera base, an end-monitoring camera disposed inside the camera adjustment frame, a brushless motor disposed inside the slide table, and a drill bit disposed at the output end of the bottom of the brushless motor, a connecting plate fixedly mounted on the bottom left side of the slide table, fixing holes respectively opened at the middle positions of both ends of the camera adjustment frame, angle adjustment grooves respectively opened at the top and bottom ends of both sides of the camera adjustment frame, fixing posts respectively fixed at the middle positions of both sides of the end-monitoring camera, angle adjustment holes respectively opened at the top and bottom ends of both sides of the end-monitoring camera, and two sets of studs respectively disposed on both sides of the camera adjustment frame.

[0006] As a further technical solution of this utility model, a 3D camera is installed and fixed at the bottom left side of the mounting base.

[0007] As a further technical solution of this utility model, the output end of the servo cylinder is fixedly connected to the top of the connecting plate.

[0008] As a further technical solution of this utility model, the camera adjustment bracket adopts a U-shaped bracket.

[0009] As a further technical solution of this utility model, the angle adjustment slide and the fixing hole respectively penetrate through the interior of the camera adjustment frame, the fixing post penetrates through the interior of the fixing hole, and the stud penetrates through the interior of the angle adjustment slide and is threadedly connected to the angle adjustment hole.

[0010] As a further technical solution of this utility model, a force sensor is installed on the top of the slide table.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: By incorporating a 3D camera, a fixed base, a servo cylinder, a slide table, a brushless motor, a camera adjustment bracket, an end-effector monitoring camera, a drill bit, a camera base, a connecting plate, an angle adjustment hole, a fixing column, an angle adjustment groove, a stud, and a fixing hole, the positioning device ensures that the line of sight of the end-effector monitoring camera intersects with the drill bit without being obstructed by the product. The adjustable camera angle allows for adjustment based on the required drilling position, preventing obstruction of the camera's viewpoint or insufficient focus from affecting the camera's accurate drilling positioning. It should be noted that in assembly line production, a drilling device typically corresponds to a fixed hole position, as the camera angle does not require frequent adjustment and can be manually adjusted. Adjusting the camera angle facilitates accurate drilling positioning, and the judgment of accurate positioning not only guides manual product positioning adjustments but also assists in subsequent automatic product positioning adjustments. By incorporating a slide table, force sensor, brushless motor, drill bit, and connecting plate, the servo cylinder drives the slide table to move downwards to drill a hole. The force sensor monitors the magnitude of the force during drilling, preventing the drill bit from deviating due to excessive force. The force sensor precisely controls the drilling force, further improving drilling accuracy. Attached Figure Description

The camera adjustment frame 7 adopts a U-shaped bracket. The angle adjustment slide 14 and the fixing hole 16 pass through the interior of the camera adjustment frame 7 respectively. The fixing column 13 passes through the interior of the fixing hole 16. The stud 15 passes through the interior of the angle adjustment slide 14 and is threaded into the angle adjustment hole 12. Furthermore, the servo cylinder 3 includes a double-acting cylinder, a servo valve, an electronic positioner, a displacement sensor, an air source, and an air circuit. The servo cylinder 3 is a fully disclosed prior art, and the air supply method of the air source is implemented in a conventional manner, so it will not be described in detail. Specifically, such as Figures 1-9 As shown, the line of sight of the installed end monitoring camera 8 intersects with the drill bit 9 and is not obstructed by the product. When adjusting the camera angle, loosen the studs 15 on both sides of the camera adjustment bracket 7 from the internal angle adjustment holes 12 on both sides of the end monitoring camera 8. Then, the end monitoring camera 8 can be rotated back and forth on the inside of the camera adjustment bracket 7 with the fixed column 13 as the axis to adjust the angle. After adjusting the angle, tighten the studs 15 on both sides inward. The camera angle can be adjusted according to the different drilling positions.

[0016] A force sensor 5 is installed at the top of the slide table 4; Specifically, such as Figures 1-7 As shown, when the servo cylinder 3 drives the slide 4 to move down and drills with the drill bit 9, the magnitude of the force during the drilling process can be monitored by setting the force sensor 5 to prevent the drill bit 9 from deviating when the force is too large during the drilling process.

[0017] Working Principle: During operation, the brushless motor 6 drives the drill bit 9 to rotate, the servo cylinder 3 controls the feed speed and distance of the drill bit 9, the 3D camera 1 is used to locate the drilling position, and the end-effector monitoring camera 8 can remotely monitor the drilling status in real time. When the servo cylinder 3 drives the slide 4 to move downwards and the drill bit 9 is used for drilling, the force sensor 5 monitors the magnitude of the force during drilling to prevent the drill bit 9 from deviating due to excessive force. The line of sight of the end-effector monitoring camera 8 intersects with that of the drill bit 9 and is not obstructed by the product. To adjust the camera angle, loosen the studs 15 on both sides of the camera adjustment bracket 7 by turning them outwards through the internal angle adjustment holes 12 on both sides of the end-effector monitoring camera 8. Then, rotate the end-effector monitoring camera 8 back and forth on the inside of the camera adjustment bracket 7 around the fixed column 13 to adjust the angle. After adjusting the angle, tighten the studs 15 on both sides inwards again. The camera angle can be adjusted according to the required drilling position to assist in precise drilling positioning.
