[0017] The following is combined with Figure 1-7 The utility model is further described as follows:
[0018] A floating auxiliary support system suitable for confined spaces, comprising a supporting device and a clamping device that cooperate with each other; the supporting device comprises a supporting seat 2 fixed on a mounting frame 1, a supporting block 3 rotatably connected to the supporting seat 2 via a pin shaft 4, a spring 5 is provided in the supporting seat 2, the top of the spring 5 is connected to a push block 6, the push block 6 penetrates the supporting seat 2 and contacts with the supporting block 3, so that the auxiliary support block tilts upward under the action of the spring force before loading, and does not tilt downward due to its own weight and fail to support the workpiece, a supporting cylinder 7 is fixed on the mounting frame 1, and a piston of the supporting cylinder 7 contacts with the supporting block 3; the clamping device comprises a clamping jaw 8 that cooperates with the end of the supporting block 3, the clamping jaw 8 is connected to the output end of a rotating cylinder 9, and the rotating cylinder 9 is fixed on the mounting frame 1.
[0019] A spherical positioning block is movably provided at the end of the support block 3. The spherical positioning block includes a spherical structure movably arranged in the spherical cavity of the support block 3. The spherical structure is connected to the positioning block. The positioning end face of the positioning block is flat and located outside the support block 3. It can self-adjust when in contact with the workpiece to ensure that the positioning end face can fit seamlessly with the workpiece. The spherical positioning block can effectively transmit the supporting force of the auxiliary support cylinder to achieve the purpose of auxiliary support of the workpiece.
[0020] When the support block 3 is not in contact with the workpiece 10, the support working end is tilted upward under the action of the spring 5. Under the action of the internal spring of the support cylinder 7, the end of the piston rod contacts the support block 3. When loading, the workpiece 10 contacts the support working end first. After the workpiece is loaded in place, the support block 3 is pressed to Figure 7In the horizontal state shown, the support cylinder 7 is hydraulically activated to provide auxiliary supporting force to support the workpiece 10. The rotating cylinder 9 drives the clamping jaw 8 to rotate and press down. The clamping jaw 8 cooperates with the supporting block 3 to provide auxiliary support and positioning for the workpiece 10 to ensure that the workpiece will not be deformed when subjected to cutting force.
[0021] The support cylinder 7 is a standard part purchased from outside, which is produced by Roemheld and has a model number of 1940-400.
[0022] The utility model is suitable for the occasion where the spring lifting auxiliary support cylinder (i.e. the support cylinder 7) cannot directly contact the workpiece due to limited space.
[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
