Description
Technical Field
The invention relates to a high-rigidity long-stroke floating support mechanism, in particular to a high-rigidity long-stroke floating support mechanism used in the field of clamps and the like.
Technical Field
In the machining field, floating bearings are often needed to meet the requirements of machining production, and generally, under the condition that parts are effectively positioned and pressed, some common floating bearings can be arranged properly, but for some parts with complex shapes or special shapes, the traditional floating bearings cannot be placed at the specified positions of the parts due to insufficient volume and rigidity of the traditional floating bearings, or cannot achieve the preset effect even if the traditional floating bearings are placed reluctantly. This requires the use of a highly rigid long travel floating support mechanism.
Disclosure of Invention

As a further improvement of the invention, one end of the locking shaft is provided with a plug.
As a further improvement of the invention, the locking shaft is sleeved with a gland C and a gland D, and the gland C and the gland D are respectively arranged on the base.
As a further improvement of the present invention, a dust ring B is provided on the gland C10.
The invention has the following advantages:
③ the mechanism can be used universally for the surfaces of workpieces with different shapes, and for the workpieces with larger size difference, only two supporting head parts need to be replaced;
④, the structural layout is reasonable, each moving part adopts a dustproof design, and the failure caused by the influence of cutting chips and the like can be effectively overcome;
⑤ the mechanism is convenient and easy to use and maintain.
Drawings
FIG. 1 is a top view of the present invention.
FIG. 2 is a sectional view taken along line A-A of the present invention.
Description of reference numerals: the device comprises a locking nut 1, a dustproof ring 2, a gland A3, a sealing ring 4, a sealing sleeve 5, a piston rod 6, a combined sealing ring 7, a base 8, a gland B9, a gland C10, a top 11, a locking shaft 12, a dustproof ring 13, a tensioning sleeve 14, a gland D15, a connecting plate 16 and an inner hexagonal socket head cap screw 17.
Detailed Description
The invention is further illustrated in the following figures.
As shown in fig. 1 to 2, the high-rigidity long-stroke floating support mechanism includes a base 8, a piston rod 6, a locking shaft 12 and a connecting plate 16, wherein two cavities are arranged on the base 8, the piston rod 6 and the locking shaft 12 are respectively arranged in the two cavities, a combined sealing ring 7 is arranged at one end of the piston rod 6, a sealing sleeve 5, a sealing ring 4, a pressing cover A3 and a dust ring a2 are sequentially sleeved at the other end of the piston rod 6, a tensioning sleeve 14 is arranged on the locking shaft 12, one end of the locking shaft 12 is connected with the piston rod 6 through the connecting plate 16, and a locking nut 1 is arranged at the connection position of the connecting plate 16 and the piston rod 6.
Further, one end of the locking shaft 12 is provided with a plug 11.
Furthermore, a gland C10 and a gland D15 are sleeved on the locking shaft 12, the gland C10 and the gland D15 are respectively installed on the base 8 through hexagon socket head cap screws 17, and the gland B9 and the gland A3 are respectively installed on the base 8 through the hexagon socket head cap screws 17.
Further, a dust ring B13 is arranged on the gland C10, and the dust ring B13 is used for preventing external dust from entering the inside of the mechanism to cause the failure of the mechanism.
The gland B9 is provided with a hydraulic seal ring, and a hydraulic oil path is arranged in the gland B9, so that when hydraulic oil enters the cavity in the base 8 through the oil path in the gland B, the piston rod 6 is pushed by the hydraulic pressure to move downwards.
The gland A3 has the same function, and the piston rod 6 is pushed to move upwards by the hydraulic oil in the gland A3.
The working process of the invention is as follows: the piston rod 6 is driven by oil pressure to reciprocate to drive the locking shaft 12 to move synchronously, the tensioning sleeve 14 is deformed by the oil pressure to lock the locking shaft 12, the length of the tensioning sleeve 14 can be customized randomly, and the stroke of the piston rod 6 can be customized randomly, so that the high-rigidity long-stroke floating support mechanism has large stroke and great locking force. Thereby ensuring high rigidity and long stroke of the floating support mechanism.
