Specific implementation mode
[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0033] Example 1, please refer to Figures 1 to 7, the present utility model provides a technical solution: a vision profile detector, including a device body 1. A positioning column 101 is fixedly installed inside the device body 1. A first crank 103 is movably embedded on the right side inside the device body 1. A forward rotation screw rod 102 is fixedly installed on the left side of the first crank 103. A reverse rotation screw rod 104 is fixedly installed on the left side of the forward rotation screw rod 102. The left outer surface of the reverse rotation screw rod 104 is movably embedded on the left inner wall of the device body 1. First sliders 105 are threadedly connected to the outer surfaces of both the forward rotation screw rod 102 and the reverse rotation screw rod 104. First chutes 106 are opened on both sides inside the device body 1. The outer surfaces of the two first sliders 105 are slidably connected to the inner surfaces of the first chutes 106. Flange members 107 are fixedly installed on the tops of the two first sliders 105. Screws 108 are movably embedded inside the two flange members 107. Second sliders 111 are threadedly connected to the outer surfaces of the two screws 108. Cameras 112 are fixedly installed on the tops of the two second sliders 111. Second cranks 109 are fixedly installed on the rear sides of the two screws 108. Second chutes 110 are opened inside the two flange members 107. Push rods 2 are fixedly installed on the opposite sides of the two first sliders 105. Air cylinders 201 are movably sleeved on the outer surfaces of the two push rods 2. The bottom outer surfaces of the two second sliders 111 are slidably connected to the inner surfaces of the second chutes 110.
[0034] In this embodiment, first place the workpiece to be detected on the positioning column 101. Rotate the first crank 103 forward to drive the forward rotation screw rod 102 to rotate. Then, the forward rotation screw rod 102 drives the reverse rotation screw rod 104. When the forward rotation screw rod 102 and the reverse rotation screw rod 104 rotate, they drive the first slider 105 to move in a relative translational direction through the first chute 106. When the first slider 105 moves, it can drive the camera 112 to perform a synchronous relative translational movement through structures such as the flange member 107, so that the camera 112 first approaches the workpiece to be detected. Then, turn on the external power switch of the camera 112 to start the camera 112 and detect the workpiece to be detected. At the same time, rotate the second crank 109 to drive the screw 108 to rotate. When the screw 108 rotates, it drives the second slider 111 to perform a translational sliding in the front-back direction through the second chute 110. Then, the second slider 111 drives the camera 112 to perform a synchronous translational movement, thereby performing a full-directional shooting detection on the workpiece to be detected. Moreover, through structures such as the forward rotation screw rod 102 and the screw 108, the position of the camera 112 can be adjusted, thereby ensuring that the device body 1 can capture all details of the stamping part. Especially for stamping parts with complex shapes or large sizes, this flexible adjustment can significantly improve the detection accuracy and integrity.
[0035] Example 2, as Figures 1 to 7As shown in the figure, the bottoms of the two air cylinders 201 are fixedly installed on the bottom side of the inner wall of the device body 1. At the other ends of the two push rods 2 and located inside the air cylinders 201, pistons 202 are fixedly installed. On the opposite sides of the two air cylinders 201, first intake pipes 203 are fixedly installed. At the other ends of the two first intake pipes 203, a pipe joint 204 is fixedly installed. At the top of the pipe joint 204, a second intake pipe 205 is fixedly embedded. At the other end of the second intake pipe 205, an airbag 207 is fixedly installed. The outer surface of the airbag 207 is movably sleeved with a first support column 206. The first support column 206 is fixedly embedded in the top side of the inner part of the device body 1. On both sides of the inner wall of the first support column 206, third chutes 208 are opened. On the inner surfaces of the two third chutes 208, third sliders 209 are slidably connected. At the tops of the two third sliders 209, first return springs 210 are fixedly installed. At the other ends of the two first return springs 210, they are fixedly installed on the top side of the inner wall of the first support column 206. On the opposite sides of the two first return springs 210, a second support column 211 is fixedly installed. At the bottom of the second support column 211, a telescopic column 212 is fixedly installed. The second support column 211 is movably embedded in the inner part of the first support column 206. At the bottom of the telescopic column 212, a pressing plate 214 is fixedly installed. A second return spring 213 is arranged on the outer surface of the telescopic column 212.
[0036] In this embodiment, when the two first sliders 105 perform relative translational movements, they will push the pistons 202 to slide inside the air cylinders 201 through the push rods 2. When the pistons 202 are moving, they can squeeze the gas inside the air cylinders 201, enter the inside of the pipe joint 204 through the first intake pipes 203, and then be transported by the pipe joint 204, so that the gas enters the inside of the airbag 207 through the second intake pipe 205, thereby enabling the airbag 207 to expand. When the airbag 207 expands, it will push the second support column 211 downward, causing the third sliders 209 to slide downward on the inner surfaces of the third chutes 208, and further causing the second support column 211 to slide downward inside the first support column 206, while driving the first return springs 210 to extend. When the second support column 211 descends, it will drive the pressing plate 214 to descend synchronously, so that the pressing plate 214 fits against the top of the workpiece to be detected, and at the same time squeezes the telescopic column 212 and the second return spring 213, causing them to contract, thereby fixing the workpiece to be detected. And through structures such as the air cylinders 201 and the pressing plate 214, not only the automatic fixation of the workpiece to be detected is realized, without manual intervention, the operation process is simplified, the detection efficiency is improved, but also the structural design can adapt to workpieces to be detected with different sizes and shapes, and can flexibly cope with workpieces to be detected with various sizes and weights, improving the flexibility and adaptability of the device body 1.
[0037] Working principle: During use, first place the workpiece to be detected on the positioning post 101. Rotate the first crank 103 in the forward direction to drive the forward screw 102 to rotate. Then, the forward screw 102 drives the reverse screw 104. When the forward screw 102 and the reverse screw 104 rotate, they drive the first slider 105 to move in a relative translational direction through the first chute 106. When the first slider 105 moves, it can drive the camera 112 to perform a synchronous relative translational movement through structures such as the flange 107, so that the camera 112 first approaches the workpiece to be detected. Then, turn on the external power switch of the camera 112 to start the camera 112 and detect the workpiece to be detected. At the same time, rotate the second crank 109 to drive the screw 108 to rotate. When the screw 108 rotates, it drives the second slider 111 to slide in the front-back direction through the second chute 110, and then the second slider 111 drives the camera 112 to perform a synchronous translational movement, thereby performing a full-directional shooting and detection of the workpiece to be detected. Moreover, through structures such as the forward screw 102 and the screw 108, the position of the camera 112 can be adjusted, thereby ensuring that the device body 1 can capture all details of the stamping part. Especially for stamping parts with complex shapes or large sizes, this flexible adjustment can significantly improve the accuracy and integrity of detection. During use, when the two first sliders 105 perform relative translational movements, they will push the piston 202 to slide inside the air cylinder 201 through the push rod 2. When the piston 202 moves, it can compress the gas inside the air cylinder 201, enter the inside of the pipe joint 204 through the first intake pipe 203, and then be transported by the pipe joint 204, so that the gas enters the inside of the airbag 207 through the second intake pipe 205, thereby enabling the airbag 207 to expand. When the airbag 207 expands, it will push the second support column 211 downward, causing the third slider 209 to slide downward on the inner surface of the third chute 208. As a result, the second support column 211 slides downward inside the first support column 206, and at the same time drives the first return spring 210 to extend. When the second support column 211 descends, it will drive the pressure plate 214 to descend synchronously, so that the pressure plate 214 fits against the top of the workpiece to be detected, and at the same time squeezes the telescopic column 212 and the second return spring 213 to make them contract, thereby fixing the workpiece to be detected. Moreover, through structures such as the air cylinder 201 and the pressure plate 214, not only the automatic fixation of the workpiece to be detected is realized, without manual intervention, simplifying the operation process and improving the detection efficiency, but also the structural design can adapt to workpieces to be detected with different sizes and shapes, can flexibly handle workpieces to be detected with various sizes and weights, and improves the flexibility and adaptability of the device body 1.
[0038] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
