Description

Technical Field

[0001] This utility model relates to the field of door and window processing technology, and specifically discloses a positioning fixture for door and window processing. Background Technology

[0002] Doors and windows require positioning fixtures during the manufacturing process to improve production efficiency.

[0003] A positioning fixture for door and window processing, Chinese Patent No. CN218576163U, includes a worktable. A first through groove is formed on one side of the worktable, and a first through hole is formed on both sides of the first through groove. Two second through grooves are formed on one side of the worktable. Four support columns are fixedly connected to one side of the worktable, and two connecting plates are fixedly connected to one side of the worktable. Each of the two connecting plates has a second through hole on one side, and a first bidirectional screw is rotatably connected inside the second through hole. The advantages of this invention are: a first operating disc drives a first screw, which in turn drives a first pressure plate thread to move up and down; a second operating disc drives a second screw, which in turn drives a second pressure plate thread to move up and down. By using the first and second operating discs to drive the first and second pressure plates, the positioned door and window are fixed, avoiding errors caused by door and window shaking during processing, making it more convenient to use.

[0004] The above-mentioned device can position doors and windows of different sizes, but it can only position one door or window at a time from multiple angles, which is not convenient for fixing two doors and windows at the same time and is inconvenient to use. Therefore, a positioning fixture for door and window processing is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a positioning fixture for door and window processing, which can clamp and position two doors and windows from multiple sides, thus facilitating workers to perform positioning and processing on two doors and windows at the same time, and is easy to use.

[0006] This utility model is implemented as follows: a positioning fixture for door and window processing includes a base frame, and the upper end of the base frame is provided with a first positioning mechanism and two second positioning mechanisms.

[0007] An auxiliary rod is fixedly connected to the upper end face of the base frame;

[0008] The first positioning mechanism includes a gear rotatably connected to the bottom end face of the base frame via a rotating shaft. Two symmetrically distributed racks are meshed on the outer wall of the gear. Two sliding grooves are formed through the upper end face of the base frame. The upper ends of the two racks are fixedly connected to driving blocks that pass through the two sliding grooves and are slidably connected to the sliding grooves. The upper ends of the two driving blocks are fixedly connected to a first limiting plate. A driving mechanism is provided below the base frame.

[0009] The second positioning mechanism includes an L-shaped plate fixedly connected to the outer wall of the first limiting plate. An electric push rod is installed on the outer wall of the L-shaped plate. The output end of the electric push rod passes through the L-shaped plate and is fixedly connected to a rectangular block. The upper end of the rectangular block is rotatably connected to two connecting rods via a rotating shaft. Two second limiting plates symmetrically distributed front and back are slidably connected to the outer wall of the first limiting plate. The other ends of the two connecting rods are respectively movably connected to the two second limiting plates via rotating shafts.

[0010] As a preferred embodiment of the positioning fixture for door and window processing according to this utility model, the driving mechanism includes a bracket fixedly connected to the lower end of the base frame, a motor installed at the lower end of the bracket, and the output end of the motor passing through the bracket and fixedly connected to a gear.

[0011] As a preferred positioning fixture for door and window processing according to this utility model, the outer wall of the first limiting plate has two T-shaped sliding grooves symmetrically distributed front and back, and the interior of each of the two T-shaped sliding grooves is slidably connected to a T-shaped slider that is fixedly connected to the second limiting plate.

[0012] As a preferred positioning fixture for door and window processing according to this utility model, the inner wall of the L-shaped plate is provided with a limiting groove, and the lower end of each rectangular block is fixedly connected with a limiting block that is slidably connected to the limiting groove.

[0013] As a preferred positioning fixture for door and window processing according to this utility model, the lower end faces of both racks are in contact with the inner wall of the bracket.

[0014] As a preferred positioning fixture for door and window processing according to this utility model, the lower end surfaces of the two first limiting plates are both in contact with the upper end surface of the base frame.

[0015] As a preferred embodiment of the positioning fixture for door and window processing according to this utility model, a controller is installed at the front end of the base frame.

[0016] The beneficial effects of this utility model are:

[0017] By placing two doors and windows on the left and right sides of the auxiliary rod at the top of the base frame, and making the outer walls of the two doors and windows abut against the left and right side walls of the auxiliary rod, the drive mechanism can drive the gear to rotate. The rotation of the gear can drive the two racks meshing with it to move in opposite directions. When the two racks move in opposite directions, they can drive the two drive blocks and the first limiting plate connected to them to move relative to each other, so that the outer walls of the two first limiting plates abut against the other outer walls of the two doors and windows, clamping and fixing the left and right side walls of the two doors and windows. The electric push rod at the left end drives the rectangular block connected to it to move. When the rectangular block moves, it drives the two connecting rods connected to it to move. During the movement of the two connecting rods, they pull the two second limiting plates connected to them to move relative to each other, which can limit the front and rear ends of the left door and window. In the same way, the other electric push rod can be activated to fix the front and rear ends of the right door and window.

[0018] In summary, this method achieves the goal of enabling multi-faceted clamping and positioning of two doors and windows, facilitating simultaneous fixing and processing of two doors and windows by workers, and providing ease of use. Attached Figure Description
