The utility model is characterized in that the frame is equipped with a medium ring, the medium ring is equipped with an inner ring; a group of revolute pairs are arranged between the frame and the medium ring; a group of revolute pairs are arranged between the medium ring and the inner ring. The utility model adopts two groups of orthogonal revolute pairs to structure an omnidirectional mechanism, thus the multi-degree-of-freedom swing is realized; the utility model is used to ensure that the action direction of the heating head keeps consistent with the action direction of the normal of the steel plate in thermal stress curved surface forming processing.
Description
Technical field:
The utility model relates to a kind of mechanical device, be particularly related to a kind of multiple degrees of freedom swing mechanism that is used for the plate thermal stress surface shaping process equipment, be used for the plate thermal stress surface shaping process and guarantee that the action direction of heating head and steel plate normal direction are consistent.
Background technology:
Main flame heat and the two kinds of patterns of high-frequency induction heating of adopting of plate thermal stress surface shaping processing.In order to realize adding thermal control automatically and improve the heating forming efficiency, the operating distance between heating head and steel plate has an optimum value, and need remain constant in the process of heating.And the action direction of heating head can guarantee that just heating head operating distance keeps constant when having only normal direction with steel plate consistent.In the steel plate curve generating process, heated steel plate original state might not be smooth, in the process of heating, curvature also changes constantly, therefore the adjustment of the operating distance of heating head and the attitude control of heating head is also become very complicated problems.In order to improve curve generating precision and production efficiency, be easy to realize adding thermal control automatically, we require the action direction of heating head consistent with the normal direction of heating region surface of steel plate shape, to keep constant operating distance.In addition, in actual production, sometimes for enhance production progress, before plate thermal stress surface shaping processing, often adopt equipment such as hydraulic press, three core roller beds to carry out predeformation processing earlier, plate thermal stress surface shaping processing will be carried out at the surface of steel plate of existing distortion like this.At present, also there is not the application of the correlation technique that the utility model relates at home in the plate thermal stress surface shaping processing.The correlation technique that the utility model relates to is to guarantee the action direction of heating head and the key technology that the steel plate normal direction is consistent in the plate thermal stress surface shaping process.If do not adopt this correlation technique, just be difficult to guarantee that the action direction of heating head is consistent with the normal direction of steel plate, be difficult to guarantee the realization of the constant maintenance of heating head operating distance, flat board can only be used for or deflection is less, and, limited the applicability and the range of work of equipment to heating control precision and the less demanding processing object of efficient.
Summary of the invention:
The purpose of this utility model is to provide a kind of multiple degrees of freedom swing mechanism that is used for the plate thermal stress surface shaping process equipment, and it can guarantee that heating head has constant operating distance, realizes adding automatically thermal control easily and improves the heating forming efficiency.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of multiple degrees of freedom swing mechanism that is used for curve generating, it mainly comprises frame, it is characterized in that: frame is equipped with middle ring, be provided with interior ring in the middle ring, between frame and middle ring, one group of revolute pair be installed, between middle ring and interior ring, one group of revolute pair is installed.
Use the utility model has the advantages that: in heating process, heating head can adapt to the geometric distortion of steel plate, remain consistent with the normal direction of steel plate, thereby guaranteed that reliably heating head has constant operating distance, realize easily adding thermal control automatically and improving the heating forming efficiency, simple for structure, dependable performance; Good to steel plate deformed adaptability; Can adapt to the requirement of plate thermal stress surface shaping processing; The utility model can be applicable to flame heat, also can be applicable to high-frequency induction heating.

The specific embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 has provided an a kind of embodiment who is used for the multiple degrees of freedom swing mechanism of plate thermal stress surface shaping process equipment, and it comprises: " C " font frame 1 (1), middle ring 2 (1), interior ring 3 (1), revolute pair 4 (4).
The utility model is a kind of multiple degrees of freedom swing mechanism that is used for curve generating, it mainly comprises frame 1, and it is different from prior art and is: ring 2 during frame 1 is equipped with, ring 3 in being provided with in the middle ring 2, between frame 1 and middle ring 2, one group of (2) revolute pair 4 is installed, between middle ring 2 and interior ring 3, one group of (2) revolute pair 4 is installed, the frame 1 of present embodiment is the C font, adopt the operating distance retainer as interior ring 3, the heating head device is placed in the central authorities of operating distance retainer, and fixing with it.Adopt the revolute pair of 2 groups of quadratures to constitute an omnidirectional mechanism, the swing of realization multiple degrees of freedom, between middle ring 2 and interior ring 3, (be designated hereinafter simply as axis and a) go up one group of (2) revolute pair 4 of design and installation, the axis that ring 3 can form around one group of (2) revolute pair 4 in making is that axis a rotates with respect to middle ring 2 at same axis; Between " C " font frame 1 and middle ring 2, the axis that ring 2 can form around one group of (2) revolute pair 4 together with interior ring 3 in going up another group of design and installation (2) revolute pair 4 with axis a orthogonal direction (being designated hereinafter simply as axis b), making is that axis b rotates with respect to " C " font frame 1.
" C " font frame 1 is installed on the movable carriage of lifting self-adapting float device, can fluctuate with the movable carriage of lifting self-adapting float device.The operating distance retainer is as interior ring 3 in the present embodiment, and it and steel plate keep in touch in the heating process, and the heating head device is placed in the central authorities of operating distance retainer, and fixing with it.When surface of steel plate is heated distortion, revolute pair by 2 groups of quadratures constitutes an omnidirectional mechanism, the operating distance retainer is easy to swing inclination thereupon under the gravity effect, realized the action direction requirement consistent with the normal direction of steel plate of heating head easily.
