Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular to a positioning fixture applicable to the processing of aluminum alloy doors and windows. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. In the production process of aluminum alloy doors and windows, some parts of the doors and windows need to be drilled.

[0003] A search revealed a Chinese patent (application number "202321563142.X") disclosing "An Aluminum Alloy Door and Window Processing Device with Positioning Function." This device includes a main structure and a positioning structure. The main structure comprises a worktable and a groove. The worktable surface has a groove with a through hole. The positioning structure includes a positioning element and a limiting element. The fixed end of the positioning element is fixedly connected to the inner wall of the groove, and the fixed end of the limiting element is installed at both ends of the positioning element and connected to both sides of the worktable. However, during the positioning process of aluminum alloy door and window components, this device can only center-grip the components and cannot accurately position them according to the drilling location, resulting in deviations in the drilling position and low practicality. Utility Model Content

[0004] This utility model provides a positioning fixture applicable to the processing of aluminum alloy doors and windows, which solves the problem proposed in the prior art that the aluminum alloy door and window processing device can only clamp the aluminum alloy door and window parts in the center, and cannot accurately position the aluminum alloy door and window parts according to the drilling position, resulting in deviation of the drilling position of the aluminum alloy door and window parts and low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture applicable to aluminum alloy door and window processing includes a fixed base and a mounting frame bolted to an aluminum alloy door and window processing equipment. A pushing mechanism is provided on one side of the mounting frame. The pushing mechanism includes a servo motor bolted to the outer wall of one side of the mounting frame, a screw connected to one end of the output shaft of the servo motor via a coupling, and a push plate bolted to the outer wall of the screw. A limiting mechanism is provided inside the mounting frame. The limiting mechanism includes a limiting plate slidably mounted on the outer wall of the mounting frame, a fixed plate bolted to the inner wall of the bottom of the mounting frame, and two gas springs respectively bolted to the outer wall of one side of the fixed plate. A... The clamping assembly includes two mounting blocks respectively bolted to one outer wall of the limiting plate, a bidirectional screw rod passing through and connected to one outer wall of the two mounting blocks via bearings, two threaded blocks respectively bolted to the outer walls of both ends of the bidirectional screw rod, two connecting rods respectively fixed to one outer wall of the two threaded blocks, and two clamping blocks respectively fixed to one outer wall of one end of the two connecting rods. The top of the fixed base is provided with two fixing mechanisms, each fixing mechanism including a mounting plate bolted to the outer wall of the top of the fixed base, a servo cylinder bolted to one outer wall of the mounting plate, and an extrusion plate with several anti-slip grooves on one outer wall.

[0007] Preferably, the mounting frame is bolted to the outer walls of both sides of the fixing seat, and a material leakage hole is opened on the outer wall at the center of the top of the mounting frame.

[0008] Preferably, a fixing block is bolted to the top outer wall of the fixing seat, and the fixing block is bolted to the top inner wall of the mounting frame. One end of the screw passes through and is connected to the outer wall of the fixing block through a bearing. The push plate is slidably mounted on the upper outer wall of the mounting frame.

[0009] Preferably, the top of the fixing plate is bolted to the inner wall of the top of the mounting frame, and one end of each of the two gas springs is bolted to the outer wall of one side of the limiting plate.

[0010] Preferably, the two mounting blocks abut against the outer walls of the mounting frame on both sides, a slide rail is provided on one side of the outer wall of the limiting plate, and the two connecting rods are slidably installed in the slide rail, the two threaded blocks abut against the outer wall of one side of the limiting plate, and the two clamping blocks abut against the outer wall of one side of the limiting plate.

[0011] The above scheme uses a limiting plate to block and limit one end of the aluminum alloy door / window, making that end flush with the center point of the material leakage hole and the drill bit. Then, the bidirectional screw is rotated, causing the two clamping blocks to move closer together, making the center line of the aluminum alloy door / window component collinear with the center point of the material leakage hole. Subsequently, the output shaft of the servo motor drives the screw to rotate, and the screw drives the push plate to move a certain distance along the surface of the mounting frame. The push plate pushes the aluminum alloy door / window component to move, and at the same time, the aluminum alloy door / window component pushes the limiting plate to move. At this time, the gas spring retracts. When the aluminum alloy door / window component is removed, the limiting plate loses the compression of the aluminum alloy door / window component, and the gas spring drives the limiting plate to reset.

[0012] Preferably, the upper part of the mounting plate is bolted to the outer wall of one side of the mounting frame, and the extrusion plate is bolted to the outer wall of one end of the servo cylinder piston rod.

[0013] The above solution uses the piston rods of two servo cylinders to move, causing two extrusion plates to contact the two sides of the aluminum alloy door and window components, thereby clamping and fixing the aluminum alloy door and window components and preventing them from shaking during drilling.

[0014] The beneficial effects of this utility model are as follows:

[0015] The limiting plate blocks and limits one end of the aluminum alloy door / window, aligning it with the center point of the material drain hole and the drill bit. Then, the double-ended screw rotates, causing two clamping blocks to move closer together, making the center line of the aluminum alloy door / window component collinear with the center point of the material drain hole. The servo motor output shaft then drives the screw to rotate, moving the push plate a certain distance along the surface of the mounting frame. The push plate pushes the aluminum alloy door / window component, which in turn pushes the limiting plate. At this point, the gas spring retracts. When the aluminum alloy door / window component is removed, the limiting plate loses its pressure, and the gas spring resets it. This system enables centered positioning of the aluminum alloy component during processing and precisely moves and positions the aluminum alloy door / window according to the drilling position, preventing drilling deviations and improving practicality.

One end of the screw 302 passes through and is connected to the outer wall of the fixing block 303 via a bearing. The push plate 304 is slidably mounted on the upper outer wall of the mounting frame 2. The mounting frame 2 is provided with a limiting mechanism 4, which includes a limiting plate 401 slidably mounted on the outer wall of the mounting frame 2, a fixing plate 402 bolted to the inner bottom wall of the mounting frame 2, and two gas springs 403 bolted to the outer wall of one side of the fixing plate 402. The top of the fixing plate 402 is bolted to the inner top wall of the mounting frame 2. 3 is existing technology, and its specific structure will not be described in detail. Meanwhile, the gas spring 403 can be flexibly selected according to production needs. One end of each of the two gas springs 403 is bolted to the outer wall of one side of the limiting plate 401. A clamping assembly 5 is provided on one side of the limiting plate 401. The clamping assembly 5 includes two mounting blocks 501 bolted to one side of the outer wall of the limiting plate 401, a bidirectional screw 502 passing through and connected to one side of the outer wall of the two mounting blocks 501 via bearings, two threaded blocks 503 screwed to the outer walls of both ends of the bidirectional screw 502, and two blocks 503 fixed to the two threaded blocks 501. 3.

[0026] Working principle: The limiting plate 401 blocks and limits one end of the aluminum alloy door and window component, making one end of the component flush with the center point of the material leakage hole and the drill bit. Then, the bidirectional screw 502 is rotated, causing the two clamping blocks 505 to move closer together, making the center line of the aluminum alloy door and window component collinear with the center point of the material leakage hole. Subsequently, the output shaft of the servo motor 301 drives the screw 302 to rotate, and the screw 302 drives the push plate 304 to move a certain distance along the surface of the mounting frame 2. The push plate 304 pushes... The aluminum alloy door and window components move, and at the same time, the aluminum alloy door and window components push the limiting plate 401 to move. At this time, the gas spring 403 retracts. When the aluminum alloy door and window components are removed, the limiting plate 401 loses the compression of the aluminum alloy door and window components. The gas spring 403 drives the limiting plate 401 to reset. The piston rods of the two servo cylinders 602 move, so that the two pressing plates 603 contact the two sides of the aluminum alloy door and window components respectively, thereby clamping and fixing the aluminum alloy door and window components to prevent the aluminum alloy door and window components from shaking during drilling.
