[0033] Embodiment 2:

[0034] See also Figure 1~Figure 5 , a construction engineering mechanical template clamping machine of the present invention, compared with the first embodiment, this embodiment also includes: a high-load adjusting member 2 includes a high-load driving member 21 fixedly installed on the top side of the tooling table 1 by bolts; the high-load driving member 21 is specifically composed of a motor and a gear; a rotating table 22 is arranged on the gear side of the high-load driving member 21 in meshing transmission; a table-shaped base 23 is fixedly installed on the middle side of the top of the rotating table 22 by bolts, an adjusting vertical beam 3 is fixedly installed on the middle end of the top side of the table-shaped base 23 by bolts, and a first hydraulic cylinder 24 with an adjusting function is fixedly installed on the side of the table-shaped base 23 by bolts, and the first hydraulic cylinder 24 is fixedly connected with the side ear plate of the sliding beam on the top side of the adjusting vertical beam 3 by bolts; a cleaning box 25 is fixedly installed on the side of the top of the tooling table 1 by bolts, and a fan with a diversion function is arranged on the side of the cleaning box 25, and a filter box with a filtering function is also arranged.

[0035] Based on the above, the working principle of a construction machinery template clamping machine is:

[0036] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0037] Second, when in use, the staff provides electric energy to the high-load adjustment member 2, the multi-stroke adjustment member 4, the clamping assembly 5 and other components through the control terminal 7; here, the motor in the high-load driving member 21 drives the gear at the bottom to mesh with the side tooth groove of the rotating table 22, so that the rotating table 22 drives the table-shaped base 23 and the adjustment vertical beam 3 related structures on its top to adjust the angle, and provides pressure to the first hydraulic cylinder 24 through the external pipeline to drive the top sliding beam of the adjustment vertical beam 3 to adjust up and down. Here, the combined outer cylinder 45 and the visual detector 47 on the adjustment vertical beam 3 can be set to collect images of the outer surface of the mechanical template, and then the cantilever clamping member 6 set on the top side cross beam of the adjustment vertical beam 3 is slid to clamp the mechanical template and lift it to the template platform on the side of the tooling table 1;

[0038] Third, when the mechanical template needs to be assembled and clamped, the staff controls the second hydraulic cylinder 41 through the control terminal 7 to drive the combined inner cylinder 42 at the top end of its piston rod to slide inside the top sliding beam of the adjustment vertical beam 3, so that the combined inner cylinder 42 and the combined outer cylinder 45 drive the multi-axis mechanical arm 46 and the clamping assembly 5 at its end to adjust the height. When the adjustment vertical beam 3 is driven by the high-load adjustment member 2 for adjustment, the combined inner cylinder 42 and the combined outer cylinder 45 can be changed to keep rotating at the same time or rotating independently by the power supply of the electromagnetic adsorption member 44 between the combined inner cylinder 42 and the combined outer cylinder 45; under the adjustment action of the multi-axis mechanical arm 46, the slide table The first clamping member 51 and the first clamping jaw 53 are displaced and approach the clamping seat 54, the suction cup assembly 56 and the flexible adsorption assembly 57 placed inside the cleaning box 25, and the suction cup assembly 56 and the flexible adsorption assembly 57 are separated from the cleaning box 25 and approach the mechanical template through the clamping action of the first clamping jaw 53. At this time, the bottom side of the electromagnetic block 572 contacts the surface of the mechanical template. Due to the squeezing force, the adjacent electromagnetic blocks 572 are more closely attached to the surface of the mechanical template under the limiting action of the clamping member 574. Here, the hard liquid capsule 573 is squeezed and fits the surface of the mechanical template. After completing the clamping process, the flexible adsorption assembly 57 can be placed inside the cleaning box 25 for dust cleaning to facilitate subsequent use.

[0039] Fourth, the electromagnetic block 572 is then powered on to generate magnetism by providing electrical energy, and the high magnetic permeability of the hard liquid capsule 573 enables the electromagnetic block 572 and the hard liquid capsule 573 to adsorb the surface of the mechanical template, and due to the support rod limitation of the clamping member 574, when encountering a mechanical template with an arc-shaped shell, the multiple groups of suction cup assemblies 56 and flexible adsorption assemblies 57 on the bottom side of the clamping seat 54 will form a fixed point as the base point, and then adhere to the surface of the mechanical template in a radial and branch-like manner. If a flat-plate mechanical template is clamped, it can be clamped directly by the first clamping jaw 53; then, while maintaining different spatial postures of the multi-stroke adjusting member 4 and the first clamping jaw 53, the mechanical template is adsorbed and forms a fixed posture, and the mechanical template is clamped and fixed by a mesh flexible adsorption with a relatively small angle rotation, which is conducive to the device being suitable for mechanical templates with different external specifications, and can also use a flexible adsorption method to reduce the deformation of the template shape caused by rigid clamping.

[0040] The present invention provides an improved clamping machine for construction engineering mechanical templates. By arranging a high-load adjustment member 2, a multi-stroke adjustment member 4 and a clamping assembly 5, it is possible to adapt to the processing requirements in the clamping process in multiple adjustment modes. The first clamping jaw 53, the flexible adsorption assembly 57 and the cantilever clamping member 6 are used to form different clamping modes for the transportation and clamping of the mechanical template. At the same time, the flexible adsorption assembly 57 is used to rotate at a relatively small angle to clamp and fix the mechanical template, which is beneficial for the device to be applicable to mechanical templates of different external specifications.
