Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6 In this embodiment of the present invention, a sheet metal contour tracking and chamfering device includes two bases 1 located on the same straight line. Each base 1 is connected to a first frame 2 via an X-axis servo drive mechanism. The first frame 2 is connected to a second frame 4 via a Y-axis servo drive mechanism 3. The second frame 4 is connected to a connecting seat 6 via a Z-axis servo drive mechanism 5. An mounting seat 7 is installed on the outer wall of the connecting seat 6. A clamping seat 8 is fixedly installed on the outer wall of the mounting seat 7. A shape template 9 is installed on the clamping seat 8. The shape template 9 is adapted to a groove on the sheet metal 29. The outer wall of the mounting seat 7 is connected by a linear guide rail. A slide block 16 is slidably mounted. A threaded cylinder 17 for driving the slide block 16 is fixedly mounted on the mounting base 7. A drive motor 21 is fixedly mounted on the slide block 16. A chamfering cutter 22 is fixedly mounted on the output shaft of the drive motor 21. A limit template 24 is adjustablely mounted on the top of the slide block 16, located on one side of the chamfering cutter 22. A first switch contact 19 and a second switch contact 20 are mounted on the top of the slide block 16. A second proximity switch 18 is mounted on the mounting base 7. The movement paths of the first switch contact 19 and the second switch contact 20 are both located directly below the second proximity switch 18.

[0021] By adopting the above-mentioned solution, in use, during the conveying process of the conveying equipment to transport the plate 29 to be chamfered, a limiting template 24 stops directly in front of the moving path of the plate 24, and the shape template 9 corresponding to the limiting template 24 is located outside the moving path of the plate. When the plate 24 contacts the limiting template 24 under the drive of the conveying equipment and pushes the slide 16 to slide on the mounting base 7, so that the second switch contact 20 is aligned with the second proximity switch 18, the corresponding X-axis servo drive mechanism drives the mounting base 7 to move in the same direction and at the same speed as the plate 29, and the corresponding Z-axis servo drive mechanism 5 drives the mounting base 7 to move forward as a whole, so as to insert the shape template 9 into the groove on the plate 29, thereby achieving the positioning of a chamfering tool 22 at one end of the plate 24.

[0022] While the mounting base 7 moves at the same speed and in the same direction as the plate 29, another limiting template 24 and the shape template 9 are driven by the corresponding three-axis drive mechanism to move at a speed greater than that of the plate 29. The limiting template 24 is pressed against the other end of the plate 29, and the shape template 9 is inserted into the groove on the plate 29. The corresponding second proximity switch 18 is triggered by the second switch contact 20, so that the chamfering tool 22 can be positioned at the other end of the plate 24.

[0023] Then, the drive motor 21 is started to drive the chamfering cutter 22 to rotate, and the mounting base 7 is driven to move along the preset chamfering path through the Z-axis servo drive mechanism 5 and the Y-axis servo drive mechanism 3, so as to complete the contour chamfering of both ends of the plate 29. Then, the two mounting bases 7 are driven to move so that the limiting templates 24 are disengaged from the plate 29, and the threaded cylinder 17 is started to drive the slide 16 to reset on the mounting base 7. The device is reset through the three-axis drive mechanism, so that the next plate 29 can be chamfered.

[0024] Specifically, in some preferred embodiments of this utility model, the X-axis servo drive mechanism is a linear servo motor mounted on the base 1, and the first bracket 2 is slidably mounted on the base 1 via a linear guide rail. The Y-axis servo drive mechanism 3 and the Z-axis servo drive mechanism 5 are both lead screw and nut pairs driven by servo motors, and the second frame 4 is slidably mounted on the first frame 2 via a linear guide rail. The connecting seat 6 is slidably mounted on the second frame 4 via a linear guide rail.

[0025] Specific combination Figure 1-5 In one embodiment of the present invention, at least one of the clamps 8 is equipped with an anti-collision sensing mechanism for the shape template 9.

[0026] Specifically, the anti-collision sensing mechanism includes a sleeve 10 fixedly installed on the clamp 8, the sleeve 10 being slidably fitted onto the shape template 9, a cylinder 12 fixedly installed at the end of the sleeve 10 away from the shape template 9, a first spring 13 installed inside the cylinder 12, a slider 14 slidably installed inside the cylinder 12, a push rod 15 fixedly installed at the end of the slider 14 facing the shape template 9, the push rod 15 abutting against the end of the shape template 9 located inside the sleeve 10, and a first proximity switch 11 fixedly installed through the outer wall of the sleeve 10.

[0027] When the plate 29 contacts the limiting template 24 and pushes the slide 16 to move on the mounting base 7 until the second proximity switch 18 is triggered by the second switch contact 20, the shape template 9 moves towards the plate 29 under the drive of the Z-axis servo drive mechanism 5. If the plate 29 is a straight-edged plate without grooves on the surface, the front end of the shape template 9 will directly abut against the side wall of the straight-edged plate. At this time, the sleeve 10 continues to move under the drive of the Z-axis servo drive mechanism 5, which will cause the shape template 9 to move into the sleeve 10 and compress the first spring 13 through the push rod 15 and the slider 14 until the end of the shape template 9 located in the sleeve 10 is sensed by the first proximity switch 11. At this time, the entire device will stop the currently running chamfering program and execute the reset program to avoid damage to the device when the plate 29 is incorrectly loaded or the program is incorrectly selected during processing.

[0028] Specific combination Figure 1-4 In one embodiment of this utility model, the slide block 16 is provided with a slide groove 23, and the limiting template 24 is slidably installed in the slide groove 23. The limiting template 24 is fixedly connected to the slide block 16 by at least two screws. The limiting template 24 is provided with a waist groove that matches the screws. A positioning bolt 25 is installed on one side of the slide block 16 located in the slide groove 23 through a threaded hole. The threaded end of the positioning bolt 25 abuts against the limiting template 24.

[0029] The groove 23 facilitates the movement of the limiting template 24 on the slide block 16. The positioning bolt 25 allows for fine adjustment of the position of the limiting template 24 by rotating it on the slide block 16 when the screws are not tightened. This facilitates adjustment of the relative position between the limiting template 24 and the chamfering cutter 22, thereby adjusting the chamfering depth of the chamfering cutter 22 on the plate 29.

[0030] Specific combination Figure 1-4In one embodiment of this utility model, the mounting base 7 is slidably mounted on the connecting base 6 via a linear guide rail. A stop block is fixedly mounted on the outer wall of the connecting base 6, and the stop block is located below the mounting base 7. An adjusting bolt 26 is threadedly connected to the outer wall of the connecting base 6 above the mounting base 7. A guide sleeve 28 is fixedly mounted on the outer wall of the mounting base 7 below the adjusting bolt 26. A guide rod is slidably mounted inside the guide sleeve 28. A spring 27 is sleeved on the guide rod. The top end of the guide rod is fixedly connected to the threaded end of the adjusting bolt 26. The top end of the spring 27 abuts against the bottom end of the adjusting bolt 26, and the bottom end of the spring 27 abuts against the top end of the guide sleeve 28.

[0031] Through the cooperation of the linear guide, spring 27, adjusting bolt 26 and guide sleeve 28, the mounting seat 7 can be pressed against the stop block on the connecting seat 6, and the mounting seat 7 can slide on the surface of the connecting seat 6 to provide a buffering effect on the mounting seat 7 in the Y-axis direction. By rotating the adjusting bolt 26 on the connecting seat 6, the pre-compression amount of the spring 27 can be adjusted.

[0032] Furthermore, in some preferred embodiments of this utility model, the X-axis servo drive mechanism, Y-axis servo drive mechanism 3, Z-axis servo drive mechanism 5, drive motor 21, control valve of threaded cylinder 17, and first proximity switch 11 and second proximity switch 18 are all electrically connected to the same control host.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
