[0002] During the production process of passenger observation window frames, the forged window frames all have process flash. In the actual operation of laser cutting to remove the flash, a laser cutting machine is used to find and align the edges of the bosses of each window frame to determine the cutting reference.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0049] In the description of the present invention, it should be understood that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0050] The purpose of the utility model is to provide a positioning tool for a window frame, which can realize accurate positioning of the window frame for laser cutting to remove burrs and improve the product qualification rate.

[0051] See also Figures 1 to 4 In order to achieve the above-mentioned purpose, the present invention provides a window frame positioning tool for positioning the window frame 100 of the observation window. The window frame 100 includes a plate body 110 with a burr in the middle and an elliptical vertical rib 120 located on one side of the plate body 110. The positioning tool includes a base and a centering component.

[0052] See also Figures 5 to 9 The base includes a top plate 210, a first support frame 220 and a second support frame 230 arranged on the top plate 210. The first support frame 220 can be adsorbed on the plate body 110 so that the vertical rib 120 is located in the first gap 240 between the first support frame 220 and the second support frame 230. A support and a clamping head rotatably connected to the support to abut against the outside of the vertical rib 120 are installed in the first gap 240.

[0053] It can be understood that the base also includes a bottom plate 270 connected to the top plate 210 through a vertical plate. The top plate 210, the bottom plate 270, and the vertical plate are interconnected to form a accommodating cavity, which is used to install the following centering component, and the accommodating cavity is connected to the first gap 240.

[0054] See also Figures 12 to 15 The centering assembly includes a lifting mechanism 310 provided with a movable rod, a first connecting rod fixedly connected to the movable rod, a second connecting rod sleeved on the top of the movable rod, and an elastic member 350 located between the first connecting rod and the second connecting rod. The top ends of the first connecting rod and the second connecting rod extend to the first gap 240 and are connected to the corresponding clamping heads.

[0055] The lifting mechanism 310 can adopt a cylinder. The lifting mechanism 310 also includes a fixed end connected to the movable rod, and the fixed end is fixedly connected to the base plate 270. The first connecting rod and the second connecting rod are moved up and down by the movement of the movable rod relative to the fixed end. The second connecting rod is sleeved on the top end of the movable rod, and the movable rod can move relative to the second connecting rod. When the second connecting rod is subjected to a certain resistance, only the movable rod and the first connecting rod fixedly connected to the movable rod continue to move.

[0056] The first support frame 220 absorbs the plate body 110 of the window frame 100, so that the vertical rib 120 of the window frame 100 is located in the first gap 240 between the first support frame 220 and the second support frame 230. A support and a clamping head that can rotate relative to the support to abut against the outer side of the vertical rib 120 are fixed in the first gap 240. The top ends of the first connecting rod and the second connecting rod of the centering assembly are connected to the corresponding clamping heads. Driven by the lifting mechanism 310, the second connecting rod moves up and first drives the clamping head to rotate to abut against the two ends of the vertical rib 120, while limiting the further upward movement of the second connecting rod. Then, the first connecting rod continues to move up and compresses the elastic member 350 until the first connecting rod drives the clamping head to rotate to abut against both sides of the vertical rib 120, thereby achieving fixation around the vertical rib 120. Through the fixed position support, the clamping head with the same rotation method, and the use of the first connecting rod and the second connecting rod moving up in turn, the window frame 100 can be accurately positioned for laser cutting to remove burrs, thereby improving the product qualification rate.

[0057] In this embodiment, the support includes a pair of first supports 251 arranged in the length direction of the top plate 210, and a pair of second supports 252 arranged in the width direction of the top plate 210, that is, the two first supports 251 are arranged on both sides of the vertical rib 120, and the two second supports 252 are arranged at both ends of the vertical rib 120; the clamping head includes a first clamping head 261 rotatably connected to the first support 251 through a pin shaft, and a second clamping head 262 rotatably connected to the second support 252 through a pin shaft. The first clamping head 261 and the second clamping head 262 both include an abutment block 263 that can be rotated around the corresponding pin shaft to abut against the vertical rib 120. Through a pair of first clamping heads 261 and a pair of second clamping heads 262, clamping in two mutually perpendicular directions can be achieved to achieve precise positioning of the window frame 100.

[0058] In some embodiments, the first connecting rod includes a first connecting plate 321 and two first rod bodies 322. The first connecting plate 321 is sleeved and fixedly connected to the movable rod, and both ends of the first connecting plate 321 are provided with a first groove body; one end of the two first rod bodies 322 is rotatably connected to the corresponding first groove body through the first rotating shaft, and the other end of the first rod body 322 is connected to the corresponding first clamping head 261.

[0059] Among them, the first clamping head 261 is provided with a third groove body for accommodating the top end of the first rod body 322, and corresponding through holes are provided on the third groove body and the first rod body 322. The shaft body is passed through the corresponding through hole, so that the first rod body 322 can rotate relative to the first clamping head 261. By the first rod body 322 being at different heights, the abutment block 263 of the first clamping head 261 can be driven to rotate to different positions to complete the clamping of the vertical rib 120.

[0060] Preferably, the second connecting rod includes a second connecting plate 331 and two second rod bodies 332. The second connecting plate 331 is sleeved on the movable rod. The top of the movable rod is connected to a limiting member 340. The limiting member 340 is used to limit the second connecting plate 331 from detaching along the top of the movable rod. The elastic member 350 is located between the first connecting plate 321 and the second connecting plate 331; one end of the two second rod bodies 332 is rotatably connected to the second connecting plate 331 through a second rotating shaft, and the other end of the second rod body 332 is connected to the corresponding second clamping head 262.

[0061] The bottom of the second rod body 332 is rotatably connected to the second connecting plate 331, and the top of the second rod body 332 is rotatably connected to the second clamping head 262. By the second rod body 332 being at different heights, the abutment block 263 of the second clamping head 262 can be driven to rotate to different positions to complete the clamping of the vertical rib 120. It should be noted that during the entire clamping process, the rotation amplitude of the second rod body 332 and the first rod body 322 is small, and there is sufficient space in the first gap 240 for the second rod body 332 and the top of the first rod body 322 to rotate.

[0062] The limit member 340 can be an adjusting screw, and the elastic member 350 can be a spring. The two ends of the elastic member 350 abut against the opposite sides of the first connecting plate 321 and the second connecting plate 331. The position of the first connecting plate 321 relative to the movable rod is fixed, and the second connecting plate 331 at the upper part can adjust the length of the spring in the axial direction of the movable rod through the adjusting screw. For example, when the end of the limit member 340 is screwed away from the first connecting plate 321, the distance between the second connecting plate 331 and the first connecting plate 321 is larger, and the distance between the two ends of the spring in the compressed state is larger. When the end of the limit member 340 is screwed close to the first connecting plate 321, the second connecting plate 331 continues to compress the spring, so that the distance between the two ends of the spring in the compressed state is smaller.

[0063] See also Figure 10 and Figure 11 In this embodiment, the first support frame 220 includes a support body 221 and a vacuum component. The support body 221 is connected to the top plate 210, and a chamber groove 222 is provided on the side of the support body 221 facing away from the top plate 210; the vacuum component includes a connecting pipe 223 connected to the chamber groove 222, an air pipe connected to the connecting pipe 223, and a vacuum pump component connected to the air pipe to make the chamber groove 222 in a negative pressure state, wherein an opening 271 for the air pipe to pass through is opened on the bottom plate 270 of the base.

[0064] In order to increase the adsorption effect of the chamber groove 222 on the plate body 110, two sealing grooves are further provided on the side of the bracket body 221 away from the top plate 210. The chamber groove 222 is located between the two sealing grooves, and a foam sealing strip 224 is provided in the sealing groove for sealing.

[0065] In this embodiment, two pairs of reference blocks 280 are further provided at the edge of the top plate 210. One pair of reference blocks 280 is located on the side opposite to the two first supports 251, and the other pair of reference blocks 280 is located on the side opposite to the two second supports 252. The cutting head 290 can find the edge and align through the reference blocks 280 for cutting the flash.

[0066] In addition, a groove 211 is provided in the middle of the bottom of the top plate 210 to accommodate the second connecting plate 331 and the top of the movable rod, providing the second connecting plate 331 and the top of the movable rod with the required moving space.

[0067] It should be noted that a first arc-shaped contact surface is provided on the top of the second support frame 230 to abut against the arc-shaped surface of the plate body 110 , thereby increasing the supporting effect of the second support frame 230 on the plate body 110 .

[0068] In summary, the present application provides a positioning tool for a window frame, wherein a cavity groove 222 capable of being negatively pressured and adsorbed on the plate body 110 is provided on the top plate 210 of the base, so that the plate body 110 is adsorbed in a preset position so that the vertical rib 120 is located in the first gap 240 between the first support frame 220 and the second support frame 230, and the movable rod of the lifting mechanism 310 is pushed out to make the first connecting plate 321 move upward, and the elastic member 350 provided between the first connecting plate 321 and the second connecting plate 331 pushes the second connecting plate 331 to move upward, and the top end of the second rod body 332 is higher than the top end of the first rod body 322, so that the second rod body 332 first drives the second clamping head 262 to rotate and clamp the outer side of the vertical rib 120, and at this time the second rod body 332 is driven by the vertical rib 120 The movement is restricted by the second clamping head 262. When the piston rod continues to move upward, the elastic member 350 is compressed, and the distance between the first connecting plate 321 and the second connecting plate 331 is reduced. Then the first rod body 322 moves to a preset height to drive the first clamping head 261 to rotate and clamp the outer side of the vertical rib 120. Through the buffering effect of the elastic member 350, the second rod body 332 and the first rod body 322 are moved to the required height successively. After the force of the centering component overcomes the friction of the adsorption force, the window frame 100 moves horizontally for centering, so that the upper surface and center of the window frame 100 are in the ideal position. Then the reference block 280 preset by the cutting head 290 can find the edge and align, and then it can be cut. After the first piece is aligned, remember the reference point, and the subsequent pieces can be cut without finding the edge and aligning.

[0069] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0070] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0071] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
