[0031] The following further describes the present utility model in conjunction with embodiments.

[0032] Through Figures 1 - 4 It can be seen that for this hydraulic swinging cylinder with a high-strength support structure, an outer housing 1 is provided, and a left support assembly 2 and a right support assembly 3 are respectively provided at the left and right ends of the outer circumference of the outer housing 1.

[0033] The left support assembly 2 includes a left support sleeve 201 and a left support base 202. The left support sleeve 201 is located at the upper section of the left support assembly 2, and the left support base 202 is located at the lower section of the left support assembly 2. The inner circumference of the left support sleeve 201 is fixedly connected to the leftmost position of the outer circumference of the outer housing 1. A longitudinally penetrating through-hole 5 is provided on the left support base 202.

[0034] The right support assembly 3 includes a right support sleeve 301 and a right support base 302. The right support sleeve 301 is located at the upper section of the right support assembly 3, and the right support base 302 is located at the lower section of the right support assembly 3. The inner circumference of the right support sleeve 301 is fixedly connected to the rightmost position of the outer circumference of the outer housing 1. A longitudinally penetrating through-hole 5 is provided on the right support base 302.

[0035] The left support base 202 and the right support base 302 can prevent the outer housing 1 from being distorted and deformed during the long-term operation of the swing cylinder, and increase the rigidity of the outer housing 1.

[0036] An intermediate support base 4 is fixedly provided at the middle position of the outer circumference of the outer housing 1. A longitudinally penetrating through-hole 5 is provided on the intermediate support base 4. By providing the intermediate support base 4 at the middle position of the outer circumference of the outer housing 1, a fixed support can be formed at the middle position of the outer housing 1, further preventing the outer housing 1 from being distorted and deformed, and forming a three-section full-range support.

[0037] The bottoms of the intermediate support base 4, the left support base 202, and the right support base 302 are locked to the robotic arm by bolts passing through the through-hole 5, thereby realizing the support and control of the robotic arm.

[0038] Anti-slip structures are respectively provided at the bottoms of the intermediate support base 4, the left support base 202, and the right support base 302 to ensure the firmness of the connection between the bottoms of the intermediate support base 4, the left support base 202, and the right support base 302 and the robotic arm, and prevent the problem of loosening or even falling off between the three support bases and the robotic arm during the long-term operation of the swing cylinder, thus avoiding potential safety hazards.

[0039] Elastic support structures are respectively provided at the bottoms of the intermediate support base 4, the left support base 202, and the right support base 302. With the combined action of the elastic support structure and the anti-slip structure, the firmness of the connection between the intermediate support base 4, the left support base 202, the right support base 302 and the robotic arm can be ensured to the greatest extent, and the problem of loosening or even falling off between the three support bases and the robotic arm during the long-term operation of the swing cylinder can be prevented, thus avoiding potential safety hazards.

[0040] The anti-slip structure is the anti-slip rib 8, which is a conical strip-shaped structure. The number of anti-slip ribs 8 is multiple, and the multiple anti-slip ribs 8 are respectively distributed at the bottom positions of the middle support seat 4, the left support seat 202, and the right support seat 302. By setting multiple anti-slip ribs 8 with a conical strip-shaped structure, the contact friction force between the middle support seat 4, the left support seat 202, the right support seat 302 and the robotic arm is increased, and the firmness of the connection between the three support seats and the robotic arm is increased.

[0041] The multiple anti-slip ribs 8 at the bottoms of the left support seat 202 and the right support seat 302 are arranged in parallel along the length direction of the outer housing 1, and the multiple anti-slip ribs 8 at the bottom of the middle support seat 4 are arranged perpendicular to the length direction of the outer housing 1.

[0042] The anti-slip ribs 8 at the bottoms of the left and right support seats are vertically distributed relative to the anti-slip ribs 8 at the bottom of the middle support seat, and the friction directions of the two are perpendicular to each other. Under the combined action of the two structures, the all-round fixation of the swing cylinder is realized, and the locking effect is more firm.

[0043] The elastic support structure includes the slot holes 6, which are respectively located at the bottom positions of the middle support seat 4, the left support seat 202, and the right support seat 302. A spring 7 is fixedly arranged inside the slot hole 6. When the spring 7 is in an uncompressed state, the bottommost positions of the spring 7 that are exposed respectively exceed the bottommost positions of the middle support seat 4, the left support seat 202, and the right support seat 302.

[0044] During installation, after the bottom positions of the middle support seat 4, the left support seat 202, and the right support seat 302 are firmly installed on the robotic arm, at this time, the spring 7 is continuously in a compressed state, applying a reverse thrust to the robotic arm, which can prevent the locking screws on the three support seats from loosening.

[0045] The number of springs 7 on the middle support seat 4 is one, located at the middle position of the bottom end of the middle support seat 4. The number of springs 7 on the left support seat 202 is two, and the two springs 7 are respectively located at the positions close to both sides of the bottom end of the left support seat 202. The number of springs 7 on the right support seat 302 is two, and the two springs 7 are respectively located at the positions close to both sides of the bottom end of the right support seat 302.

[0046] The multiple springs 7 form an I-shaped support structure, which saves manufacturing costs on the premise of ensuring that the springs 7 can exert sufficient reverse elastic force for support.

[0047] The elastic support structure is an elastic gasket. The number of elastic gaskets on the middle support seat 4 is one, located at the middle position of the bottom end of the middle support seat 4. The number of elastic gaskets on the left support seat 202 is two, and the two elastic gaskets are respectively located at the positions near both sides of the bottom end of the left support seat 202. The number of elastic gaskets on the right support seat 302 is two, and the two elastic gaskets are respectively located at the positions near both sides of the bottom end of the right support seat 302.

[0048] In the uncompressed state of the elastic gasket, the lowest positions where the elastic gasket leaks out respectively exceed the lowest positions of the middle support seat 4, the left support seat 202 and the right support seat 302.

[0049] As another design solution of the elastic support structure, the elastic gasket can be fixed to the bottom of the three support seats in various ways, such as pasting, snap fixing, screw locking, etc., which is convenient for disassembly. More importantly, its function is the same as that of the spring 7. When using the elastic gasket, on the premise of ensuring that it can exert sufficient reverse elastic force support, it can more effectively reduce the manufacturing cost.

[0050] The middle support seat 4 is in a long strip shape. There is a groove at the middle position of the middle support seat 4, and fixing cylinders are respectively arranged at both ends of the middle support seat 4. The groove is fixedly connected to the bottom of the outer shell 1. The fixing cylinders at both ends of the groove are respectively located on both sides of the outer circumference of the outer shell 1, and the top parts of the two fixing cylinders are located at the middle position in the vertical direction of the outer shell 1.

[0051] However, the above are only specific embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention patent, should still fall within the scope covered by the claims of the present invention.
