Problems solved by technology
These methods are either cumbersome, the mechanism volume is large, or there are too many auxiliary processes, and the processing efficiency is not high. Therefore, it is necessary to invent a tool for calibrating and clamping the roundness of the flexible barrel section, which can meet the requirements of the installation of the barrel sections with various diameters and roundness. Clamping requirements, at the same time, the tooling fixture mechanism is relatively simple, and the volume is also small

Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with specific embodiments.
[0016] A roundness calibration and clamping device for a flexible cylinder segment based on a pressure steering mechanism, such as figure 1 As shown, it mainly includes the circumferential base 1 and the supporting claw 2. The diameter of the circumferential base is designed according to the diameter of the workpiece to be clamped. At the same time, the number of clamping supporting claws is also based on the diameter of the base. change to change.
[0017] Such as figure 2 , image 3 , Figure 4 shown. The support claw 2 is in the shape of number "7", which includes the inside baffle plate 7 of the cylinder section, the pressure plate 8, the double slider pressure steering mechanism 9, the cylinder push rod 10 and the cylinder 11, wherein the inside baffle plate 7 of the cylinder section is located on the support claw 2 At the left end of the half part, the pressin...

The invention belongs to the field of correcting and clamping devices, and particularly relates to a flexible tube section circular degree correcting and clamping device based on pressure steering mechanisms. The flexible tube section circular degree correcting and clamping device comprises circumference bases (1) and supporting jaws (2), the diameter of the circumference bases is designed according to that of a workpiece to be clamped, clamping supporting mechanisms can be finely adjusted in the radial direction of a tube section, and the flexible tube section circular degree correcting and clamping device is suitable for the tube sections of various diameters and circular degrees and has the correction function on circular degree locating. The clamping force is controlled through a servo air cylinder, meanwhile, the double-sliding-block mechanisms are utilized to achieve pressure steering, and the occupied space of the mechanisms is reduced.
Description
technical field [0001] The technology belongs to the field of calibration and clamping devices, and in particular relates to a roundness calibration and clamping device of a flexible cylinder segment based on a pressure steering mechanism. Background technique [0002] In the milling process of large-scale barrel workpieces, due to the large diameter of the barrel section, the roundness of the surface of the barrel section before finishing is also low, and the general general-purpose fixtures are often difficult to meet the clamping requirements of this type of workpiece, and the neutrality is not good. Well, the clamping accuracy is not high, and the clamping force is too high to cause deformation of the workpiece. These factors will cause the machining accuracy of milling to not be guaranteed. [0003] At present, when dealing with such problems, some use large self-centering fixtures to solve the centering problem; some use the method of adding inner support tooling to re...
