[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0042] The core of the utility model is to provide a multi-angle adjustment mechanism for a screw locking machine head, which can be used for screw locking at multiple angles.

[0043] Please refer to Figures 1-4 A multi-angle adjustment mechanism for a screw locking machine head includes a fixing plate 1, a screw locking machine head 3, an angle adjustment part 5 and a position adjustment mechanism 6. The fixing plate 1 is fixedly installed on the screw locking machine. A mounting plate 2 is hinged on the fixing plate 1. The screw locking machine head 3 is installed on the mounting plate 2. The screw locking machine head 3 is used to lock the screws of the workpiece. The angle adjustment part 5 is installed on the mounting plate 2 and is used to control the rotation angle of the mounting plate 2. The angle of the screw locking machine head 3 is quickly adjusted according to the angle of the screw on the workpiece. The position adjustment mechanism 6 is installed on the mounting plate 2 and is used to control the position of the screw locking machine head 3.

[0044] It should be noted that the embodiment of the present invention does not limit the specific structure of the angle adjustment member 5.

[0045] In some embodiments, the angle adjustment member 5 can use a motor, such as a brushless motor or a stepper motor, etc., and connect its output end to the mounting plate 2 to drive the rotation of the mounting plate 2, thereby completing the change of the angle of the screw locking head 3.

[0046] In other embodiments, the angle adjustment member 5 can be a pneumatic cylinder, electric cylinder, etc. installed on the fixed plate 1. Through the hinge between its protruding end and the mounting plate 2, when it is extended or retracted, it can drive the mounting plate 2 to rotate, thereby completing the change of the angle of the screw locking machine head 3.

[0047] In addition, the embodiment of the present invention does not limit the specific structure of the position adjustment mechanism 6.

[0048] In some embodiments, the position adjustment mechanism 6 can be a pneumatic cylinder, an electric cylinder, etc. installed on the mounting plate 2. By installing the screw locking head 3 on its protruding end, the position of the screw locking head 3 can be adjusted by its extension and retraction.

[0049] In other embodiments, the position adjustment mechanism 6 can be a screw 602 rotatably mounted on the mounting plate 2. By threading the screw locking head 3 and the screw 602, the position adjustment of the screw locking head 3 can be achieved when the motor drives the screw 602 to rotate.

[0050] When in use, first fix the fixing plate 1 on the screw locking machine to facilitate the installation of the entire device on the screw locking machine. The fixing plate 1 is hinged with a mounting plate 2, and the screw locking machine head 3 is installed on the mounting plate 2. The screw locking machine head 3 is used to lock the screws of the workpiece. The screw locking parts on the screw locking machine head 3 can be replaced with appropriate sizes according to production requirements. The angle adjustment part 5 is installed on the mounting plate 2 and is used to control the rotation angle of the mounting plate 2. The angle of the screw locking machine head 3 is quickly adjusted according to the angle of the screw on the workpiece, thereby improving the versatility of the device. The position adjustment mechanism 6 is installed on the mounting plate 2 and is used to control the position of the screw locking machine head 3, which reduces the time required for manual alignment and further improves production efficiency. For complex workpieces with multiple screw holes, the system can perform locking operations on multiple positions simultaneously or sequentially without waiting for a single position. At the same time, it can easily cope with the screw locking requirements of various angles and positions on complex workpieces. This flexibility makes it applicable to workpieces of various shapes and specifications without the need to replace or adjust equipment.

[0051] Please refer to Figures 1-4 In order to further improve the angle accuracy during the angle adjustment process of the screw locking machine head 3, in some embodiments, a reducer 4 is also included. The reducer 4 is located between the angle adjustment member 5 and the mounting plate 2. The output end of the reducer 4 is fixedly connected to the mounting plate 2. The angle adjustment member 5 adopts a motor and is connected to the input end of the reducer 4. That is to say, by adding the reducer 4, the angle accuracy during the angle adjustment process of the screw locking machine head 3 is improved.

[0052] Please refer to Figures 1-4 In some embodiments, the position adjustment mechanism 6 includes a mounting frame 601 and a driving member 604. A screw 602 is rotatably mounted on the mounting plate 2, and its axis is perpendicular to the rotation axis of the mounting plate 2. The mounting frame 601 and the screw 602 are threaded together. The screw locking head 3 is arranged on the mounting frame 601, and the driving member 604 drives the screw 602 to rotate. That is to say, by adopting the matching structure of the screw 602 and the motor, the position of the screw locking head 3 can be quickly and accurately adjusted. The screw uses a high-precision ball screw 602 or a trapezoidal screw 602, which has a self-locking function to ensure that the lifting arm will not slide down due to gravity when the power is off or the drive stops.

[0053] Please refer to Figures 1-4 In order to further improve the stability of the screw locking machine head 3 during movement and avoid position deviation, in some embodiments, the position adjustment mechanism 6 also includes a limit rod 603, which is installed on the mounting plate 2 and is arranged parallel to the axis of the screw 602. The mounting frame 601 and the limit rod 603 are slidably matched. That is to say, by adding a limit rod 603 parallel to the axis of the screw 602, the screw locking machine head 3 remains stable during sliding.

[0054] It should be noted that in the embodiment of the present invention, a slide rail 705 can be used instead of the limit rod 603. Specifically, a slide rail 705 is set on the mounting plate 2, and the mounting frame 601 is slidably installed on the slide rail 705, so as to limit the sliding process of the mounting frame 601.

[0055] In some embodiments, the driving member 604 is a motor, which drives the lead screw 602 to rotate. The motor can be of different types, such as a stepper motor, a brushed motor, or a brushless motor.

[0056] Please refer to Figures 1-4 In order to reduce the hard collision of the screw locking machine head 3 during the process of screwing the workpiece, which may cause damage to the workpiece or the machine head, in some embodiments, a floating mechanism 7 is provided between the screw locking machine head 3 and the mounting frame 601 for placing the screw locking machine head 3 in a floating state. That is to say, by adding a floating mechanism 7 that places the screw locking machine head 3 in a floating state, the damage caused by the screw locking machine head 3 during operation is reduced.

[0057] In some embodiments, the floating mechanism 7 includes a first floating rod 702 and a first elastic member 704. The first floating rod 702 is arranged parallel to the sliding rod and is provided on the mounting frame 601. The screw locking head 3 is slidingly arranged along the first floating rod 702. The first elastic member 704 drives the screw locking head 3 to move away from the mounting plate 2. That is to say, by sliding the screw locking head 3 on the first floating rod 702 and driven by the first elastic member 704, the screw locking head 3 can have an elastic effect on the first floating rod 702, thereby reducing damage to the screw locking head 3.

[0058] In some embodiments, the floating mechanism 7 also includes a second floating rod 706 and a second elastic member 707. The second floating rod 706 is connected to the screw locking head 3 and slides with the mounting plate 2. The second elastic member 707 drives the screw locking head 3 to move away from the mounting plate 2. That is to say, the second floating rod 706 and the second elastic member 707 are used to further ensure the floating effect of the screw locking head 3 to adapt to a more complex screw locking use environment.

[0059] It should be noted that the second floating rod 706 in the embodiment of the present invention can be a long screw, and an end cap is provided at the end of the long screw away from the screw locking head 3, and it is threadedly connected to the screw locking head 3 when in use. By rotating the long screw, the distance between the end cap of the long screw and the screw locking head 3 is changed, thereby adjusting the degree of its floating to meet the needs of different working conditions.

[0060] It should be noted that, in the embodiment of the present invention, the first elastic member 704 may adopt different structures.

[0061] In some embodiments, the first elastic member 704 is a pneumatic spring, which is arranged parallel to the first floating rod 702, and the floating effect of the screw locking head 3 is achieved by the pre-tightening force of the pneumatic spring.

[0062] In other embodiments, the first elastic member 704 is a spring sleeved outside the first floating rod 702, and the floating effect of the screw locking head 3 is achieved by the pre-tightening force of the spring.

[0063] Please refer to Figures 1-4 In order to facilitate the adjustment of the floating pre-tightening force of the screw locking head 3, in some embodiments, the floating mechanism 7 also includes an adjusting nut 703, which is threadedly installed on the first floating rod 702, and the end of the first elastic member 704 is in contact with the adjusting nut 703, that is, by adjusting the thread of the adjusting nut 703 on the first floating rod 702 to adjust the position of the adjusting nut 703, thereby achieving the adjustment of the pre-tightening force of the first elastic member 704 itself, which is convenient and fast, and has good structural practicality.

[0064] Please refer to Figure 4 In order to make the screw locking head 3 have better stability during the floating function, in some embodiments, the floating mechanism 7 also includes a slide rail 705 and a slider 701. The slide rail 705 is arranged along the axial direction of the first floating rod 702 and is arranged on the mounting plate 2. The slider 701 is slidably arranged on the slide rail 705 and is fixedly connected to the screw locking head 3. The slide rail 705 is added to limit the floating direction of the screw locking head 3, thereby improving the stability of the floating process of the screw locking head 3.

[0065] That is to say, the focus of the embodiment of the present invention is that: by utilizing the cooperation of the angle adjustment part 5 and the position adjustment mechanism 6, the screw locking head 3 can quickly adjust the angle of the screw locking head 3 according to the angle of the screw on the workpiece, thereby improving the versatility of the device. The position adjustment mechanism 6 is installed on the mounting plate 2 and is used to control the position of the screw locking head 3, which reduces the time required for manual alignment and further improves production efficiency. For complex workpieces with multiple screw holes, the system can perform locking operations on multiple positions simultaneously or sequentially without waiting for a single position, and can easily cope with the screw locking requirements of various angles and positions on complex workpieces. This flexibility makes it applicable to workpieces of various shapes and specifications without the need to replace or adjust equipment, which is conducive to further improving production efficiency.

[0066] 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.

[0067] The above is a detailed introduction to the multi-angle adjustment mechanism of the screw-locking machine head provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention.
