[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] like Figure 1-7As shown, a product assembly depth detection device includes an adjustment component 1, a support 2, a lifting mechanism 3, and a detection component 4. The adjustment component 1 is fixedly installed in a fixed position, the support 2 is fixedly installed on the adjustment component 1, the lifting mechanism 3 is fixedly installed on the support 2, and the detection component 4 is fixedly installed on the lifting mechanism 3. The lifting mechanism 3 is used to drive the detection component 4 to slide along the Z-axis, and the adjustment component 1 is used to adjust the position of the detection component 4 in the X-axis and Y-axis directions. The adjustment component 1 includes a first adjustment component 11 and a second adjustment component 12. The adjustment directions of the first adjustment component 11 and the second adjustment component 12 are perpendicular to each other. The first adjustment component 11 is fixedly installed in a fixed position, the second adjustment component 12 is fixedly installed on the upper end face of the first adjustment component 11, and the support 2 is fixedly installed on the second adjustment component 12. The first adjustment component 11 is used to adjust the position of the detection component 4 in the X-axis direction, and the second adjustment component 12 is used to adjust the position of the detection component in the Y-axis direction. Thus, the detection component 4 can be aligned with the workpiece to be detected by the lifting mechanism 3, the first adjustment component 11, and the second adjustment component 12, and the detection action can be completed by the lifting mechanism 3 driving the detection component.
[0033] like Figure 5-7 As shown, the first adjustment component 11 includes a first mounting base 111, a first fixing block 112, and a first bolt 113. A first fixing block 112 is respectively provided on both sides of the first mounting base 111. A first bolt 113 is threaded onto each first fixing block 112, and one end of the first bolt 113 can abut against the first mounting base 111. The first mounting base 111 has multiple first through holes evenly distributed and arranged parallel to each other. Each first through hole is a rectangular or elliptical through hole. A first locking bolt is slidably disposed within each first through hole. The first locking bolt can slide within the first through hole, and the sliding direction is the same as the axial direction of the first bolt 113. The first locking bolt is used to fix the relative position of the first mounting base 111 and the fixed position; the second adjustment component 1... 2 includes a second mounting base 121, a second fixing block 122, and a second bolt 123. A second fixing block 122 is provided on each side of the second mounting base 121. A second bolt 123 is threaded onto each second fixing block 122, and one end of the second bolt 123 can abut against the second mounting base 121. Multiple second through holes are evenly distributed on the second mounting base 121, and the multiple second through holes are arranged parallel to each other. Each second through hole is a rectangular through hole or an elliptical through hole. A second locking bolt is slidably disposed in each second through hole. The second locking bolt can slide in the second through hole, and the sliding direction is the same as the axial direction of the second bolt 123. The second locking bolt is used to fix the relative position of the second mounting base 121 and the first mounting base 111. The bracket 2 is fixed on the second mounting base 121.
[0034] like Figure 3As shown, the lifting mechanism 3 includes a base, a slide, a lead screw, and a drive motor. The base is vertically mounted on the bracket 2. The drive motor is fixedly mounted on one end of the base. The lead screw is located inside the base, with one end fixedly connected to the output end of the drive motor and the other end rotatably connected to the base. The two sides of the slide are slidably connected to the base, and the middle of the slide is threadedly connected to the lead screw. The detection component 4 is fixedly mounted on the slide. The lifting drive mechanism also includes a limiting component, which is used to limit the limit stroke of the slide. The limiting component includes a first sensor 31 and a limiting member 32. Several first sensors 31 are arranged on one side of the base, and the several first sensors 31 are arranged along the axial direction of the lead screw. The limiting member 32 is fixedly mounted on the slide, and one end of the limiting member 32 can abut or sense the execution end of any first sensor 31. The first sensor 31 is a photoelectric sensor in the prior art, model EE-SX3081, and the drive motor is in the prior art, model DP-TXL-002.
[0035] In implementation, the lifting mechanism 3 is first used to move the detection component 4 to the vicinity of the workpiece to be inspected. The position of the first mounting base 111 in the X-axis direction is adjusted through the first through hole, which in turn adjusts the position of the bracket 2 in the X-axis direction, further adjusting the position of the lifting mechanism 3 in the X-axis direction, and finally adjusting the position of the detection component 4 along the X-axis direction. The first mounting base 111 is then secured by the first bolt 113. Similarly, the position of the second mounting base 121 on the first mounting base 111 along the Y-axis direction is adjusted through the second through hole, thereby adjusting the position of the detection component 4 relative to the workpiece to be inspected along the Y-axis direction. Thus, the first adjusting component 11, the second adjusting component 12, and the lifting mechanism 3 enable the detection component 4 to accurately position itself on the workpiece to be inspected. The initial inspection determines the position of the first adjusting component 11 and the second adjusting component 12. Afterwards, continuous testing can be performed. When the testing parts are replaced, the first adjustment component 11 and the second adjustment component 12 can be adjusted again. The structure is simple, easy to disassemble and install manually, and can be quickly adjusted to meet the needs of automated production lines. It is also low in cost. In implementation, two first sensors 31 are respectively set on one side of the base. One is used to limit the slide table to the upper limit stroke, and the other is used to limit the slide sleeve to the lower limit stroke. When the lower end of the limiting component 32 moves to the execution end of the first sensor 31, the first sensor 31 sends a signal and transmits it to the controller. The controller causes the drive motor to stop rotating, thereby preventing the slide table from colliding with both ends of the base and protecting the lifting mechanism 3.
[0036] like Figure 1 and Figure 4As shown, the detection component 4 includes a fixed frame 41, a positioning component 42, and a detector 43. The fixed frame 41 is fixedly mounted on the slide table, and the detector 43 is fixedly mounted on the fixed frame 41. The periphery of the positioning component 42 is slidably connected to the fixed frame 41, and the lower end of the positioning component 42 is fixedly connected to the detector 43. The positioning component 42 includes a moving plate 421 and guide rods 422. The two guide rods 422 are arranged in parallel, and their peripheries are slidably connected to the fixed frame 41 respectively. The bottom end of each guide rod 422 is fixedly connected to the moving plate 421, and a limit plate is provided at the top of each guide rod 422. The lower end of the limit plate can abut against the fixed frame 41. The limit plate is used to prevent the guide rod 422 from sliding out. The moving plate 421 is provided with... The positioning assembly 42 also includes a compression spring. Each guide rod 422 is surrounded by a compression spring, and the two ends of the compression spring are fixedly connected to the upper end of the moving plate 421 and the bottom end of the fixed frame 41, respectively. The detector 43 includes a second sensor 431 and a third sensor 432. The second sensor 431 and the third sensor 432 are fixedly mounted on the fixed frame 41. The moving plate 421 has a third through hole in the middle. The sensing end of the second sensor 431 is located in the third through hole of the moving plate 421. The sensing end of the third sensor 432 is fixed on the moving plate 421. The lower end face of the sensing end of the third sensor 431 can abut against the upper end face of the side wall of the workpiece. The lower end face of the sensing end of the second sensor 432 can abut against the bottom surface of the groove at the upper end of the workpiece.
[0037] In implementation, the second sensor 431 and the third sensor 432 are existing pull-rod type displacement sensors, both model KTC1-100. The lifting mechanism 3 drives the detector 43 downwards, which in turn drives the moving plate 421 downwards, causing the moving plate 421 to first contact the surface of the workpiece to be detected, thus bringing the third sensor 432 into contact with the workpiece surface. At this point, the initial values of the second sensor 431 and the third sensor 432 are set. Then, the lifting mechanism 3 continues to operate, causing the fixed frame 41 to move downwards. During this time, the second sensor 431 remains stationary, while the output end of the third sensor 432 moves inwards. As the fixed frame 41 moves downwards, the second sensor... As the output end of sensor 431 gradually enters the workpiece, when the output end of the second sensor 431 comes into contact with the internal parts of the workpiece, and the second sensor 431 changes within a certain range, it indicates that the lower end face of the sensing end of the second sensor 432 has come into contact with the bottom surface of the upper groove of the workpiece. Then, the second sensor 431 sends a signal and transmits it to the controller. The controller stops the lifting mechanism 3 and reads the value of the third sensor 432 at this time. The depth from the internal parts of the workpiece to the workpiece surface is calculated by using the value of the third sensor 432 at this time, the initial value of the second sensor 431, and the thickness of the moving plate 421. The entire measurement process is simple, fast, stable, and accurate.
[0038] The working principle of a product assembly depth detection device is as follows: The detection device is installed at the detection station. The position of the detection component 4 is adjusted by the first adjustment component 11, the second adjustment component 12 and the lifting mechanism 3 so that the detector 43 is aligned with the workpiece to be detected. The lifting mechanism 3 drives the positioning component 42 to move to the surface of the workpiece so that the sensing end of the third sensor 432 is in contact with the surface of the workpiece. The lifting mechanism 3 continues to work and drives the fixed frame 41 to continue to move downward so that the second sensor 431 is in contact with the bottom surface of the groove at the upper end of the workpiece. Then the second sensor 431 sends a signal and transmits it to the controller. The controller stops the lifting mechanism 3. The depth of the internal parts of the workpiece to the surface of the workpiece is calculated by the values of the third sensor 432, the second sensor 431 and the thickness of the moving plate 421 at this time.
[0039] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
