[0023] EMBODIMENT

[0024] Referring to Figures 1 to 5 The turning device for the frame structure composed of angle steel welding of the embodiment includes lifting positioner 1, turnover seat 2 installed on lifting positioner 1 and multiple compression fixing assemblies 3 for compressing and fixing the frame structure arranged on turnover seat 2, and turnover seat 2 is equipped with one group or more clamping assemblies for clamping and fixing the angle steel in the frame structure, and the direction of clamping and fixing the angle steel of the clamping assembly is perpendicular to the direction of compressing and fixing the frame structure of compression fixing assembly 3. Turnover seat 2 can be driven to turn and lift by lifting positioner 1, so that the frame structure fixedly installed on turnover seat 2 is turned over.

[0025] One group or more clamping assemblies are arranged on turnover seat 2, and the clamping assembly and compression fixing assembly 3 fix the frame structure in the direction perpendicular to each other, so that the number of compression fixing assemblies 3 can be reduced under the condition of ensuring the installation stability of the frame structure, and the simple and compact structure is improved, and the cost is reduced.

[0026] The clamping assembly in the embodiment comprises a fixed clamping piece 4, a movable clamping piece 5 and a clamping driving mechanism 6 arranged on the turnover seat 2, the fixed clamping piece 4 is fixedly arranged on the turnover seat 2, the clamping driving mechanism 6 is connected with the movable clamping piece 5 and can drive the movable clamping piece 5 to move close to the fixed clamping piece 4 to clamp the angle steel and move away from the fixed clamping piece 4 to release the angle steel; the clamping assembly has the advantages of simple structure, low cost, simple control and stable and reliable clamping.

[0027] The clamping driving mechanism 6 in the embodiment is a telescopic air cylinder. In other embodiments, the clamping driving mechanism 6 can also adopt other mechanisms capable of driving the movable clamping piece 5 to move close to and away from the fixed clamping piece 4.

[0028] The embodiment specifically comprises a plurality of clamping assemblies, which are arranged at intervals along the length direction of the angle steel to improve the clamping stability.

[0029] The turnover seat 2 in the embodiment is provided with an anti-collision mechanism for preventing the frame structure from colliding with the clamping driving mechanism 6 when the frame structure is installed; the anti-collision mechanism can avoid collision between the frame structure and the clamping driving mechanism 6 when the frame structure is installed, thereby preventing the clamping driving mechanism 6 from being damaged, ensuring stable and reliable work, and prolonging the service life of the clamping driving mechanism 6.

[0030] The anti-collision mechanism in the embodiment is a guardrail 7 which is arranged outside the clamping driving mechanism 6 and has a height higher than that of the clamping driving mechanism 6 on the turnover seat 2. Since the height of the guardrail 7 on the turnover seat 2 is higher than that of the clamping driving mechanism 6, even if the position of the frame structure deviates greatly during the process of placing the frame structure on the turnover seat 2, the guardrail 7 can prevent the frame structure from directly contacting and colliding with the clamping driving mechanism 6. The anti-collision mechanism in the form of the guardrail 7 has the advantages of simple structure and low cost.

[0031] In the embodiment, at least one pressing and fixing assembly 3 is installed on the turnover seat 2 in a position-adjustable manner through a moving mechanism; the position of the pressing and fixing assembly 3 can be adjusted as needed, so that the position of the pressing and fixing assembly 3 pressing the frame structure can be adjusted, and the pressing and fixing assembly 3 can be applied to frame structures of various specifications and sizes, thereby saving cost, improving use flexibility and use convenience.

[0032] The moving mechanism in the embodiment comprises a moving seat 21 and a guide rail 22 arranged on the turnover seat 2, and the moving seat 21 is provided with a sliding block which is in sliding cooperation with the guide rail 22; the moving mechanism has the advantages of simple structure, low cost and simple adjustment.

[0033] In the embodiment, the turnover seat 2 is provided with a guiding mechanism for guiding the frame structure to be placed on the turnover seat 2; the guiding mechanism can guide the frame structure to be placed on the turnover seat 2 during the process of placing the frame structure on the turnover seat 2, thereby reducing the difficulty of placing the frame structure by artificial or using a lifting tool, and improving the installation convenience and efficiency.

[0034] The guide mechanism in the embodiment comprises two guide plates 8 arranged at intervals for respectively corresponding to limit the position range of the two ends of a single angle steel in the fixed frame structure, and the end of the guide plate 8 away from the turnover seat 2 is provided with an inclined guide surface 81 gradually extending outwardly in the direction away from the turnover seat 2. The inclined guide surfaces 81 of the two guide plates 8 correspond to form a horn-shaped guide port, and the maximum width of the horn-shaped guide port is greater than the length of the angle steel from one end to the other end, so that the angle steel can enter the horn-shaped guide port within a certain position range in the length direction of the angle steel and be placed on the turnover seat 2 under the limitation of the horn-shaped guide port. Since only two guide plates 8 are needed to be arranged, the guide mechanism has the advantages of simple structure, low cost and easy manufacturing and assembly.

[0035] The guide mechanism in the embodiment further comprises one or more side guides 9 for limiting the position range of the side surface of a single angle steel in the fixed frame structure, and the end of the side guide 9 away from the turnover seat 2 is provided with an inclined guide part 91 gradually extending outwardly in the direction away from the turnover seat 2.
