[0002] During machining and assembly, for example, assembling a nut on a workpiece (pressing the nut into a mounting hole on the workpiece) requires placing the nut at a designated location on the machine tool. The workpiece is then placed on the machine tool, where the mounting hole on the workpiece and the nut must be aligned. This alignment is particularly challenging when using hexagonal nuts, and only after the workpiece and nut are aligned can assembly processing be performed on the machine tool.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings, and specific implementation methods will be given.

[0022] like Figure 1 、 Figure 2 、 Figure 3As shown, the positioning and detection device includes a frame, a workbench 1 installed on the frame, a mounting position set on the workbench 1, a placement component for placing a workpiece 10, and a detection component installed on the frame. The workbench 1 is fixed on the frame, and the mounting position is used to place the nut 2. During actual design, a placement groove can be designed at the mounting position to clamp the nut 2, and the nut 2 is placed on the mounting position. Then, the workpiece 10 is moved to a suitable position and assembled with the nut 2 through the placement component.

[0023] The placement component includes a clamping member for clamping the workpiece 10 and an adjusting member for adjusting the position of the clamping member. The adjusting member includes a first slide 3 slidably connected to the frame, a second slide 5 slidably connected to the first slide 3, and a mounting plate 6 slidably connected to the second slide 5. The sliding directions of the first slide 3, the second slide 5, and the mounting plate 6 are perpendicular to each other. By designing the sliding directions of the first slide 3, the second slide 5, and the mounting plate 6, the position of the mounting plate 6 can be adjusted within a spatial range. A cylinder for driving the first slide 3 to slide is installed on the frame, a cylinder for driving the second slide 5 to slide is installed on the first slide 3, and a cylinder for driving the mounting plate 6 to slide is installed on the second slide 5.

[0024] The clamping member includes a suction cup 9 that is detachably connected to the mounting plate 6. Specifically, different types of suction cups 9 can be selected according to the material of the workpiece 10. For example, a rubber suction cup 9 can be used for a lightweight workpiece 10 with a smooth surface, while an electromagnetic suction cup 9 can be used for a workpiece 10 made of steel. In this embodiment, a mounting block 8 is bolted to the mounting plate 6, and the suction cup 9 is fixed on the mounting block 8.

[0025] The detection component includes a positioning part installed on the frame and a positioning controller for receiving the positioning signal of the positioning part. The signal output end of the positioning controller is used to control the movement of the adjusting part. The positioning controller can be a single-chip microcomputer in the existing technology or a controller with a program control function. The controller can control the extension and contraction of multiple cylinders used to drive the first slide 3, the second slide 5, and the mounting plate 6 to slide, thereby controlling the position of the workpiece 10 adsorbed by the suction cup 9 and adjusting the position of the workpiece 10.

[0026] The positioning member includes a first sensor 11 and a second sensor 12 detachably connected to the frame. The first sensor 11 and the second sensor 12 respectively detect two adjacent edges of the workpiece 10. Specifically, the first sensor 11 and the second sensor 12 are both proximity switches in the prior art. The first sensor 11 and the second sensor 12 are both bolted to the same horizontal plane on the frame. In this embodiment, taking the vertical sliding of the first slide 3 and the sliding of the second slide 5 and the mounting plate 6 in the horizontal plane as an example, by setting the distance that the first slide 3 can move downward, when the first slide 3 moves downward to a specified height, the second slide 5 and the mounting plate 6 can be slid so that the workpiece 10 gradually approaches the first sensor 11 and the second sensor 12. When the first sensor 11 and the second sensor 12 detect the workpiece 10, the second slide 5 and the mounting plate 6 can be controlled to stop sliding.

[0027] In actual design, after the positioning controller controls the second slide plate 5 and the mounting plate 6 to stop sliding, if the suction cup 9 is an electromagnetic suction cup 9, the positioning controller can also be designed to control the suction cup 9 to release the suction on the workpiece 10, thereby restoring the entire assembly to facilitate subsequent assembly work. In addition, the positioning component can also include a distance sensor 4 for detecting the downward movement distance of the first slide plate 3, thereby facilitating the control of the downward movement distance of the first slide plate 3.

[0028] When in use, place the nut 2 at the mounting position on the workbench 1, then slide the first slide 3, the second slide 5, and the mounting plate 6 so that the mounting plate 6 is located above the stacking area of ​​the workpiece 10, then slide the first slide 3 downward so that the suction cup 9 absorbs the workpiece 10, and then continue to slide the first slide 3, the second slide 5, and the mounting plate 6 so that the workpiece 10 is located above the workbench 1. Figure 1 Status shown.

[0029] First, control the first slide 3 to slide down so that the workpiece 10 and the first sensor 11 and the second sensor 12 are at the same height, and then adjust the position of the workpiece 10 by sliding the second slide 5 and the mounting plate 6. When the first sensor 11 and the second sensor 12 detect the workpiece 10, the second slide 5 and the mounting plate 6 can be controlled to stop sliding. At this time, continue to control the first slide 3 to slide down so that the workpiece 10 is pressed down on the nut 2.

[0030] In another embodiment of the present invention, Figure 4 、 Figure 5As shown, during the stacking process of the workpiece 10, there will inevitably be a problem of orientation deviation. If the workpiece 10 is directly adsorbed by the suction cup 9, there will be a problem with the orientation of the workpiece 10. For this reason, in this embodiment, the mounting block 8 is not directly bolted to the mounting plate 6, and the mounting plate 6 is rotatably connected to the turntable 7. The turntable 7 is detachably connected to the mounting block 8, that is, the mounting block 8 is bolted to the turntable 7, and the mounting block 8 is used to install the suction cup 9. Specifically, the suction cup 9 is fixed to the mounting block 8.

[0031] At least two limiting rods 13 are vertically slidably connected to the mounting plate 6, and a cylinder for driving the limiting rods 13 to slide is installed on the mounting plate 6. The limiting rods 13 are distributed on both sides of the turntable 7. By sliding the limiting rods 13, the limiting rods 13 are clamped on both sides of the workpiece 10, thereby limiting the workpiece 10. In order to facilitate the limiting rods 13 to guide the workpiece 10 to a certain extent when the workpiece 10 is slightly deviated in direction, the lower end of the limiting rod 13 is provided with an inclined guide surface 14, which is used to guide the workpiece 10 in turning. Specifically, when the limiting rod 13 slides down, the guide surface 14 contacts the side of the workpiece 10, driving the workpiece 10 to deflect and gradually straighten until the two sides of the workpiece 10 are respectively in contact with the limiting rods 13 or the guide surfaces 14 located on both sides. When the direction of the workpiece 10 is greatly offset, a pressure sensor is installed on the limit rod 13. After the limit rod 13 moves downward, the lower end of the limit rod 13 will directly contact the upper surface of the workpiece 10 and cannot continue to slide down. At this time, the pressure sensor is triggered, and the staff can manually adjust the direction of the workpiece 10 according to the signal changes of the pressure sensor.
