[0037] Embodiment

[0038] As Figures 1-4 shown, this embodiment provides a multi-directional clamping assist arm, including: a base 1, a column 2 fixedly connected to the base 1, a main arm 3, a sub-arm 4, a vertical arm 5 arranged in the vertical direction, and a handrail 7 provided on the vertical arm 5. The upper end of the column 2 is provided with a rotating shaft 21 arranged in the vertical direction and capable of rotating along its own axis; one end of the main arm 3 is hinged to a balance cylinder 22 fixedly connected to the rotating shaft 21; the sub-arm 4 is horizontally hinged to the other end of the main arm 3; one end of the vertical arm 5 is hinged to the sub-arm 4, and the other end is fixedly connected with a fixture mounting flange 6; further included is: a direction adjustment assembly 8 provided between the vertical arm 5 and the fixture mounting flange 6 for adjusting the direction of the fixture mounting flange 6. By adjusting the orientation of the fixture mounting flange 6 through the direction adjustment assembly 8, the fixture can perform multi-directional clamping, with simple operation, convenient use, and a wide range of applications.

[0039] Among them, the direction adjustment component 8 includes: a fixed block 81 arranged on the vertical arm 5, a rotating member 82 arranged at the bottom end of the vertical arm 5, and a driving member 83 arranged between the fixed block 81 and the rotating member 82. The driving member 83 provides power to drive the rotating member 82 to rotate, so that the clamp mounting flange 6 can rotate to adapt to the clamping operation of different workpieces.

[0040] At the same time, one end of the driving member 83 is rotatably connected to the fixed block 81, and the other end is rotatably connected to the rotating member 82, that is, both ends of the rotating member 82 can rotate, so that the rotating member 82 can directly and quickly adjust the direction of the clamp mounting flange 6, thereby improving the working efficiency of the clamp.

[0041] In this embodiment, the end of the rotating member 82 is fixedly connected to the clamp mounting flange 6, that is, the clamp mounting flange 6 is in indirect contact with the vertical arm 5, so that the clamp mounting flange 6 rotates with the rotating member 82, ensuring that the clamp can be clamped in multiple directions.

[0042] In this embodiment, a connecting arm 9 is provided between the balancing cylinder 22 and the main arm 3. The connecting arm 9 connects the main arm 3 with the balancing cylinder 22, plays a transition role, and ensures the stability and firmness of the balancing cylinder 22, thereby making the entire power-assisting arm more stable.

[0043] In this embodiment, one end of the connecting arm 9 is fixedly connected to the end of the main arm 3, and the other end is provided with a stabilizing block 91. The stabilizing block 91 stabilizes both the connecting arm 9 and the balancing cylinder 22 so that neither of them shakes during operation, thereby ensuring the stability of the balancing cylinder 22 during operation and further ensuring the stability of the entire power-assisting arm.

[0044] In this embodiment, two balancing cylinders 22 are provided, which are symmetrically connected to both sides of the connecting arm 9, so that the connecting arm 9 is evenly stressed, ensuring the stability of the balancing cylinder 22 when working, and further enhancing the stability of the power-assisting arm. The two balancing cylinders 22 greatly increase the driving force of the main arm 3, so that the clamp on the clamp mounting flange 6 can clamp workpieces of different types and weights, with a wide range of applications, and can ensure the stability of the entire power-assisting arm, so that the clamping operation can be carried out stably without shaking.

[0045] In this embodiment, it further includes a moving component 10 disposed at the bottom of the base 1. The moving component 10 includes a support base 101 fixedly connected to the base 1 and rollers 102 respectively disposed at the bottom of the support base 101. By moving the rollers 102, the support base 101 is driven to move, and thus the entire assisting arm can be moved, enabling it to quickly move to the designated working position without consuming a large amount of manpower, saving time, and improving work efficiency.

[0046] In this embodiment, a plurality of fixing components 11 are disposed on the support base 101. The fixing components 11 are used to limit the position of the assisting arm and prevent it from moving after positioning. The fixing components 11 include a connecting block 111 disposed on the upper surface of the support base 101, a vertically disposed fixing rod 112, a positioning block 113 inserted into the inside of the connecting block 111 and disposed on the fixing rod 112, a fastener 114 for fixing the connecting block 111 and the positioning block 113, and a grip rod 115 horizontally disposed at the top end of the fixing rod 112. The fixing rod 112 cooperates with the positioning block 113 to initially fix the connecting block 111, so that the support base 101 does not move. The fastener 114 performs secondary fixing on the positioning block 113 and the connecting block 111, so that the connecting block 111 and the positioning block 113 do not shift, ensuring the fixing effect of the fixing rod 112, making the support base 101 more stable, and ensuring the stability and firmness of the assisting arm.

[0047] Certainly, the fixing rod 112 and the positioning block 113 are in threaded connection. By rotating the grip rod 115, the vertical position of the fixing rod 112 is adjusted, so that the fixing rod 112 can stably act on the ground. Together with the positioning block 113, the fixing rod 112 will not shake or shift, etc., and has a good fixing effect, making the assisting arm stable and firm during operation, and thus improving work efficiency.

[0048] In addition, an air control box 12 connected to the balance cylinder 22 is disposed on the side wall of the upper end of the rotating shaft 21. The air control box 12 is mainly based on a pneumatic system and uses compressed air as a power source to control and drive the balance cylinder 22, which has the advantages of simple reliability, low cost, fast response speed, convenient control, and high work efficiency.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
