Fig. 1-2 show an expanding sleeve type clamping mechanism provided by the utility model, the expanding sleeve type clamping mechanism comprises an installation base 1 for connecting equipment, a clamping base body 3 which is arranged on the installation base 1 and is of a hollow structure and is divided into at least two halves through a slicing groove 2, and a clamping base 4 which is arranged on the top end of the clamping base body 3, is of a hollow inverted trapezoidal structure, is divided into a number which is the same as that of the clamping base body 3 by the slicing groove 2 and is used for clamping a workpiece, and a chromium plating coating is arranged on the hollow surface 12 of the clamping base 4. When the clamping mechanism is used, after each workpiece is fed through the truss manipulator, the existing part of each workpiece extends into the inner cavity of the clamping base 4, then the machine tool stretches the expanding sleeve type clamping mechanism backwards in the existing and unprocessed state of the workpiece, the clamping base 4 is of a hollow inverted trapezoidal structure, the diameter of the inner cavity of the clamping base 4 is reduced under the extrusion of an external base body, the purpose of clamping the workpiece is achieved, half of the cutting grooves 2 is determined according to requirements, the diameter reduction range of the inner cavity of the clamping base 4 is larger when the cutting grooves are larger than half of the cutting grooves, so that more workpieces of different models can be clamped, the hollow surface 12 of the clamping base 4 is provided with a chromium plating coating, the structural rigidity of the expanding sleeve type clamping mechanism is increased, the clamping stability is improved, and the service life is prolonged from 3 months to 12 months.
Be provided with a plurality of being used for the installation on mount pad 1 mount hole 5 of mount pad 1, still be provided with the centre bore 6 that is used for playing the positioning action on mount pad 1, 6 inner walls of centre bore are provided with the seal groove 7 that is used for placing sealing washer 8, through set up mount hole 5 on mount pad 1, are convenient for install whole cover formula clamping mechanism that rises on equipment, realize the sealed mounting to whole shell type clamping mechanism that rises through placing sealing washer 8 in seal groove 7.
The side surface of the clamping base 4 is provided with a limiting groove 9, the top surface of the clamping base 4 is provided with a positioning hole 10, and the side surface of the clamping base 4 is provided with a positioning groove 11 opposite to the limiting groove 9. The limiting groove 9, the positioning hole 10 and the positioning groove 11 are arranged on the clamping base 4, so that the whole expansion sleeve type clamping mechanism is simple, convenient and quick to install and use, the installation and positioning time is shortened, and the extending position is limited.
The expansion sleeve type clamping mechanism enhances the clamping stability through the structural design, enhances the wear resistance of the clamping surface through the chromium-plated coating on the hollow surface of the clamping base, prolongs the service life of the whole expansion sleeve type clamping mechanism, and is simple in structure, low in cost and easy to manufacture.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
