DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3 The schematic diagram of the whole structure of the clamping device for manufacturing metal doors and windows of the utility model is shown. Figure 1-Figure 3 A clamping device for manufacturing metal doors and windows in this embodiment includes a processing table 100, and independent clamping units are arranged around the upper end of the processing table 100. The clamping unit includes a slide 200 slidably installed along the edge line of the processing table 100, and a slide 210 is slidably installed on the upper end of the slide 200 along its length direction, and the slide 200 and the slide 210 move in coordination in the xy direction. At the same time, the slide 200 and the slide 210 are driven to reciprocate by a driving device, and a clamp 220 is also arranged on the upper part of the slide 210. A plurality of distance measuring components 300 corresponding to each clamping unit are arranged on the edge of the processing table 100, and a rotating support component 400 that can drive it to rotate horizontally is also arranged at the bottom of the processing table 100.

[0021] The upper part of the processing table 100 is provided with a plurality of first slide grooves 1001 which are slidably matched with the corresponding slide 1 200 respectively, the upper part of the processing table 100 is fixed with an electric push rod 1 230 whose output shaft is connected to the side of the slide 1 200, the upper part of the slide 1 200 is provided with a second slide groove 2001 which is slidably matched with the slide 2 210, and the upper part of the slide 1 200 is also provided with an electric push rod 240 which can drive the slide 210 to move back and forth along the second slide groove 2001. It can be understood that the electric push rod 1 230 pushes the slide 1 200 and the slide 2 210 to form a y-direction movement, and the electric push rod 2 240 pushes the slide 2 210 to form an x-direction movement. In this way, the door and window frames positioned on the fixture 220 can be adjusted laterally and centripetally without manual positioning operation, which is simple and fast. In addition, the fixture 220 here can adopt a pneumatic fixture, a hydraulic fixture or an electric fixture, etc., which is not limited in this embodiment.

[0022] A window 1002 is provided on the processing table 100 near the four corners. In actual welding processing, the front and back diagonals of the metal door and window frames need to be welded. Therefore, after the four door and window frames are firmly positioned, the welder located above can weld the front diagonals, and the welder located below can penetrate through the window 1002 and weld the back diagonals. There is no need to remove the workpiece and then reposition it, which also prevents the clamp from hindering welding, effectively improving the welding processing efficiency of doors and windows.

[0023] The distance measuring assembly 300 includes a mounting plate 310 fixed to the outer edge of the processing table 100, and a laser distance meter 320 mounted on the inner side of the mounting plate 310. In this embodiment, in order to adjust the clamped door and window frames to the central axis of the processing table 100, the laser distance meter 320 can be used to quickly and accurately measure the distance of the ends of the door and window frames. The control unit will calculate the difference between the length of the door and window frames and the side length of the processing table 100 to obtain half of the difference. Therefore, when the distance between the end of the door and window frame and the mounting plate 310 just reaches half of the difference, the movement and adjustment of the slide 210 is stopped. The structure is simple, the design is reasonable and efficient, and the positioning deviation errors that may be caused by manual operation are effectively avoided, thereby improving the processing specifications and efficiency of doors and windows.

[0024] The rotating support assembly 400 includes a turntable 410 fixed at the center of the bottom of the processing table 100, a support column 420 rotating at the bottom and inner side of the turntable 410 through bearings, and a servo motor 430 arranged at the inner top of the support column 420 and with the output shaft connected to the axis of the turntable 410. In order to facilitate manual or robotic arm loading, the servo motor 430 drives the turntable 410 and the processing table 100 to rotate horizontally, so that the four clamping units are switched to the loading station in turn, which greatly reduces the difficulty and preparation time of loading and is conducive to efficient clamping and positioning.

[0025] Furthermore, the clamping device for manufacturing metal doors and windows is also provided with a master control unit, namely a PLC controller. It can be understood that the staff can uniformly control and set the various driving units and detection units of the clamping device through the PLC controller, so as to achieve the purpose of fast clamping and efficient locking.

[0026] In summary, the clamping device for manufacturing metal doors and windows of the present embodiment, when in use, switches the four clamping units on the processing table 100 to the loading stations in turn by rotating the support assembly 400, and places the door and window frames in turn into the fixture 200 for preliminary clamping and stabilization, making the loading simpler and faster, and then the laser rangefinder 320 detects the relative distance of the door and window frames in real time, and the controller controls the four slides 210 through the electric push rod 2 and adjusts the positions of all the door and window frames synchronously until the axial direction of the engagement is reached, and then the slide 1 200 drives the four door and window frames to engage diagonally, thereby achieving the effect of rapid clamping and positioning, effectively avoiding positioning deviation errors that may be caused by manual operation, and improving the specification quality and processing efficiency of metal doors and windows.

[0027] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
