[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figs. 1 to 4 As shown, a window frame corner positioning device in this embodiment includes: a workbench 1, a placement rack 5 and a mounting plate 10. A first positioning block 2 is fixedly installed at the top corner of the upper surface of the workbench 1, and a second positioning block 3 is installed on the outer side of the upper end of the workbench 1 by screws. A limiting strip 4 located inside the lower end of the second positioning block 3 is fixedly installed on the upper surface of the workbench 1.

[0028] The first positioning block 2 is used to limit the top corner of the window frame body to improve the docking effect of the two window frame bodies, and the second positioning block 3 is used to further limit the docking of the two window frame bodies. At the same time, the upper end of the workbench 1 has a threaded groove that matches the screw, so as to facilitate the adjustment and fixation of the second positioning block 3 in different positions according to the limiting strip 4, the screw and the threaded groove, so as to be suitable for window frame bodies of different sizes.

[0029] The upper end of the workbench 1 is equipped with a placement rack 5, and the upper outer side of the placement rack 5 is equipped with an air pump 6. The lower outer side of the air pump 6 is connected to an air bag 7, and the lower outer side of the air bag 7 is equipped with a connecting rod 8. The lower surface of the connecting rod 8 is attached with a first rubber sheet 9.

[0030] The longitudinal section of the placing rack 5 is in the shape of "U", which is convenient for installing the parts without affecting the placing of the window frame body, so as to facilitate the positioning work of the upper and lower sides of the window frame body. At the same time, the air pump 6 is used for inflating and deflating the workbench 1. When the air pump 6 inflates, the volume of the air bag 7 becomes larger, and at this time, the lower end of the air bag 7 moves out of the placing rack 5, so as to drive the connecting rod 8 to slide downward. Conversely, when the air pump 6 deflates, the air bag 7 drives the connecting rod 8 to slide upward. Thus, it is convenient to adjust the height of the connecting rod 8 and the first rubber sheet 9 according to the amount of gas in the air bag 7, so as to make the first rubber sheet 9 closely connected with the upper surface of the window frame body under the action of the air bag 7 and the connecting rod 8.

[0031] The outer side of the first positioning block 2 is internally penetrated by an adjusting rod 13, one end of the adjusting rod 13 away from the first positioning block 2 extends to the rear end of the placing rack 5, the placing rack 5 is connected with the workbench 1 in a sliding manner, the adjusting rod 13 is connected with the first positioning block 2 in a threaded manner, and the adjusting rod 13 is connected with the placing rack 5 in a rotating manner.

[0032] The adjusting rod 13 adjusts the position of the placing rack 5, and the lower end of the placing rack 5 is provided with a protruding structure extending into the workbench 1. When the position of the placing rack 5 is adjusted, the lower end of the placing rack 5 slides in the workbench 1. At this time, the protruding structure can limit the placing rack 5 to avoid moving out of the workbench 1.

[0033] The lower end of the placing rack 5 is internally provided with a mounting plate 10, the mounting plate 10 is internally rotatably provided with a roller 11, the lower surface of the placing rack 5 is attached with a second rubber sheet 12, the lower end of the placing rack 5 is internally provided with a spring 14 located directly below the mounting plate 10, and the placing rack 5 is symmetrically arranged about the vertical central axis of the first positioning block 2, and the first rubber sheet 9 is located directly below the roller 11.

[0034] The mounting plate 10 installs the roller 11, which facilitates smooth movement of the roller 11 when the window frame body is placed, and reduces the required force. At the same time, the spring 14 is used to support the mounting plate 10 and the roller 11, so that the height of the roller 11 is higher than that of the second rubber sheet 12 when it is not extruded by external force, avoiding the influence of the second rubber sheet 12 on the placing of the window frame body.

[0035] Working principle

[0036] First, the whole stable is placed on the designated plane, and then the two window frame bodies that need to be assembled are placed in the two groups of placing racks 5 through the rollers 11, and the top corners of the two window frame bodies are in contact with the first positioning blocks 2, and then the positions of the second positioning blocks 3 are adjusted to be connected with the inside of the top corners of the two window frame bodies, and then the screws are rotated to be threadedly connected with the corresponding threaded grooves, so that the positions of the second positioning blocks 3 can be fixed.

[0037] The air pump 6 is started to inflate the air pump 6, at this time the volume of the air bag 7 is increased, so that the lower end of the air bag 7 is moved out of the placing rack 5, and the connecting rod 8 is driven to slide downward at the upper end of the placing rack 5, at this time the first rubber sheet 9 can be tightly connected with the upper surface of the window frame body under the action of the connecting rod 8.

[0038] With the extrusion of the connecting rod 8 and the first rubber sheet 9 on the window frame body, the mounting plate 10 and the roller 11 are subjected to downward extrusion force, so that the mounting plate 10 moves downward to the inside of the lower end of the placing rack 5, and at the same time the spring 14 is compressed, at this time the upper end of the roller 11 is lower than the position of the second rubber sheet 12, so that the lower surface of the window frame body is tightly connected with the second rubber sheet 12. Thus, the first rubber sheet 9 and the second rubber sheet 12 can be tightly connected with the upper and lower sides of the window frame body respectively, thereby effectively improving the positioning effect of the window frame body and avoiding the phenomenon that the window frame body moves and affects the butt joint effect.

[0039] The adjusting rod 13 is rotated to be threadedly connected with the first positioning block 2, at this time the end of the adjusting rod 13 away from the first positioning block 2 is rotated with the placing rack 5, at this time the placing rack 5 can move towards the first positioning block 2 under the action of the adjusting rod 13, thereby facilitating the synchronous movement of the tightly positioned window frame body, so that the two window frame bodies are tightly connected, thereby playing a role of compensating the gap at the butt joint of the two window frame bodies, and effectively reducing the gap at the butt joint.

[0040] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradictions), in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described; these embodiments which are not explicitly written should also be considered as the scope of the present application.
