Description

Technical Field

[0001] This utility model relates to the field of automatic screw fastening technology, specifically a gantry-type automatic screw fastening mechanism. Background Technology

[0002] The gantry-type automatic screw fastening mechanism is an automated device mainly used to automatically fasten screws during machining processes.

[0003] For example, Chinese Patent CN104741907A (A Gantry-Type Automatic Screw Locking Mechanism) includes a base plate, support blocks, an X-axis module, a slide rail, a slider, a main support plate, a Y-axis module, a screw locking module fixing plate, and an automatic screw locking module. Two support blocks are fixedly connected to the base plate. Each support block is fixedly connected to an X-axis module and a slide rail, with a slider connected to the slide rail. The main support plate is connected to two sets of X-axis modules and two sets of sliders at both ends. A Y-axis module is connected to the main support plate, and a screw locking module fixing plate is connected to the Y-axis module. Two or more automatic screw locking modules are connected to the screw locking module fixing plate. This invention can simultaneously fix two or more automatic screw locking modules to the screw locking module fixing plate, enabling the simultaneous locking of two or more products. The machine body structure minimizes vibration during operation, thus ensuring the highest dimensional accuracy, thereby improving work efficiency and quality, and reducing labor intensity and production costs.

[0004] However, existing gantry-type automatic screw-locking mechanisms require the installation of corresponding fixing structures based on the different sizes of the objects when fixing them. This necessitates frequent replacements, which is time-consuming and labor-intensive. Furthermore, the mechanisms have poor applicability and require multiple fixing structures for backup, resulting in high investment costs and limited flexibility and applicability. Therefore, they do not meet current needs. To address this, we propose a gantry-type automatic screw-locking mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a gantry-type automatic screw-locking mechanism to solve the problems mentioned in the background art. When fixing objects, the existing gantry-type automatic screw-locking mechanisms require the installation of corresponding fixing structures of different sizes according to the different sizes of the objects. This requires frequent replacement, which is time-consuming and labor-intensive. Furthermore, the applicability is poor, and multiple fixing structures are required for backup, resulting in high investment costs and poor flexibility and applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gantry-type automatic screw-locking mechanism, comprising: a first upright plate, a second upright plate disposed on one side of the first upright plate, a fixing component disposed between the bottom ends of the first upright plate and the second upright plate, a first limiting component disposed at the upper end of one end of the fixing component, a second limiting component disposed at the upper end of the other end of the fixing component, and both the first limiting component and the second limiting component are positionally adjustable along the fixing component, a limiting groove is disposed on the inner wall of the first upright plate and the second upright plate near the bottom end, and the fixing component moves along the limiting groove, and anti-falling components are disposed at both ends of the limiting groove.

[0007] Preferably, the fixing component includes a fixing base and an adjustment groove, and multiple adjustment grooves are provided. The first limiting component and the second limiting component move along the adjustment grooves. Both ends of the fixing base are provided with limiting slide plates, and the limiting slide plates move back and forth along the limiting slide grooves.

[0008] Preferably, the front surface of the fixed base is provided with a through groove, which passes through the fixed base from front to back, and the adjustment groove is interconnected with the through groove.

[0009] Preferably, both the first limiting component and the second limiting component include a corner limiting seat, the lower end of which is provided with a threaded post, and multiple threaded posts are provided, and the threaded posts are inserted along the adjusting groove. Both the first limiting component and the second limiting component also include a pressing seat, and the pressing seat is threadedly connected to the threaded post.

[0010] Preferably, the anti-fall component includes an anti-fall baffle, an extension plate is provided on one side surface of the anti-fall baffle, and a through hole is provided at one end of the anti-fall baffle, with the through hole penetrating the anti-fall baffle.

[0011] Preferably, the anti-fall component further includes a fixing post, one end of which is provided with a ring plate on its outer wall, and an installation notch is formed between the two ring plates and the fixing post. The anti-fall baffle is fitted into the installation notch through a through hole and rotates along the installation notch.

[0012] Preferably, a first movable module is provided at the upper end of the second upright plate, a connecting frame is provided at the movable end of the first movable module, a second movable module is provided inside the connecting frame, a mounting frame is provided at the movable end of the second movable module, a third movable module is provided at the front end of the mounting frame, a protective box is provided at the movable end of the third movable module, a drive motor is provided at the top of the protective box, a screwdriver is provided at the output end of the drive motor, and the screwdriver is located at the lower end of the protective box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides an adjustment groove on the upper surface of the fixed base. The adjustment groove is interconnected with the through groove. When installing the first limiting component and the second limiting component, the threaded post of the first limiting component and the second limiting component are respectively inserted into the adjustment groove at the corresponding position. The threaded post moves along the adjustment groove, thereby adjusting the distance between the first limiting component and the second limiting component. It is suitable for objects of different sizes, improving flexibility and applicability. After adjustment, the object is squeezed and fixed by tightening the squeezing seat. The object is diagonally fixed by the first limiting component and the second limiting component, reducing the contact area and facilitating disassembly and installation. This solves the problem that when fixing objects, the existing gantry-type automatic screw locking mechanism requires the installation of a corresponding size fixing structure based on the different sizes of the object. This requires frequent replacement, which is time-consuming and labor-intensive, and has poor applicability. Multiple fixing structures are required for backup, resulting in high investment costs and poor flexibility and applicability.

[0015] (2) By setting limiting slide grooves on the inner walls of the first and second upright plates near the bottom, and setting anti-fall components at both ends of the limiting slide grooves, when installing the fixed base, the limiting slide plate is inserted along the limiting slide groove, which improves the connection stability and makes it less prone to positional deviation. After the end surface of the limiting slide plate is flush with the end surface of the limiting slide groove, the anti-fall baffle is rotated to block the end of the limiting slide groove, thus preventing the limiting slide plate from slipping off, thereby fixing the fixed base to the first and second upright plates, which facilitates installation and disassembly and improves flexibility.
