Abstract
The utility model relates to a clamping mechanism for a workpiece box main shaft of a gear milling machine, comprising a box, a workpiece box main shaft, and a piston and a cylinder both arranged outside one end of the workpiece box main shaft, wherein a bearing gland is pressed at the outer ring of a bearing, and being characterized in that an arresting disc is arranged between the workpiece box main shaft and the piston through a fastening element; a piston stroke gap is formed between the contact surfaces of the arresting disc and the piston; a gap is formed between the contact surfaces of the arresting disc and the bearing gland; a mounting groove for assembling a spring and a jacking header is arranged on the arresting disc; and the spring and the jacking header are mounted in the mounting groove. The clamping mechanism for the workpiece box main shaft of the gear milling machine has the following advantages that powerful extrusion force and frictional force are produced on the piston and the arresting disc by a hydraulic system, thereby realizing the clamping of the workpiece box main shaft; hydraulic oil is discharged from the hydraulic system and disc spring is restored in shape to push the jacking header so that the piston returns to an initial position; and therefore, the release of the workpiece box main shaft is completed. The mechanism is designed to realize quick clamping of the main shaft before the gear drawing process, and is simple in structure, easy for assembling, convenient for numerical control, flexible in reaction and obvious in clamping effect.
Description
Technical field
The utility model belongs to the technology of Machine Tool field, particularly relates to a kind of mill teeth machine workpiece box main shaft clamp mechanism.
Background technology
Along with improving constantly of China's living standards of the people, automobile has been come into huge numbers of families gradually, becomes the walking-replacing tool of people's trip.In auto manufacturing, the application of curved tooth awl gear is extensive day by day.At present, adopt mill teeth machined spiral bevel gear, can realize producing in enormous quantities, and production efficiency is high.Owing in the process, draw the tooth working (machining) efficiency higher than mill teeth working (machining) efficiency, need guarantee that workpiece keeps motionless man-hour in each tooth process drawing tooth to add simultaneously, when after drawing the tooth process finishing, needing minute tooth, then should main shaft be loosened.Therefore need mill teeth machine workpiece box main shaft to have the clamping uncoupling gear, can satisfy the requirement of drawing tooth processing.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be easy to assemble and have the mill teeth machine workpiece box main shaft clamp mechanism that clamps and loosen function.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Mill teeth machine workpiece box main shaft clamp mechanism; Comprise casing, be installed in workpiece box main shaft on the casing, be arranged on workpiece box main shaft one end outside piston and cylinder body through bearing; Said bearing outer ring is pressed with bearing gland; It is characterized in that: through securing member arresting disc is housed between said workpiece box main shaft and the piston, is provided with the piston stroke gap between the contact-making surface of said arresting disc and piston, be provided with the gap between the contact-making surface of said arresting disc and bearing gland; Be shaped on the mounting groove that is used to assemble spring and top on the said arresting disc, spring and top are housed in the said mounting groove.
The utility model can also adopt following technical scheme:
Be shaped on three mounting grooves on the said arresting disc.
Mounting groove on the said arresting disc is a circular trough.
Be equipped with disk spring and top successively in said each circular trough.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; When needs draw tooth to add man-hour to spiral bevel gear, the workpiece box main shaft is clamped, this moment, hydraulic system was injected hydraulic oil to cylinder body; Hydraulic oil promotes piston, until compressing arresting disc.Under the pressure that hydraulic system produces, produce powerful extrusion force and frictional force between piston, arresting disc, bearing gland three, and the three is compressed, arresting disc is connected through securing member with the workpiece box main shaft, can realize the clamping of hydraulic system to the workpiece box main shaft.In the time of need loosening the workpiece box main shaft, the oil liquid pressure off-load, the disk spring strain resiles, and promotes the top, returns initial position thereby promote piston.Have gap between piston and the arresting disc contact-making surface II this moment, when the workpiece box main shaft rotates, can avoid piston and arresting disc to rub.This clamp mechanism is for realizing that have the mill teeth machine that draws the tooth function is drawing tooth process front clamp main shaft that strong condition is provided, and is not only simple in structure, is easy to assembling, with low cost, and is convenient to numerical control, is quick on the draw, to clamp effect remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the arresting disc structural representation of the utility model.
Among the figure: 1, workpiece box main shaft; 2, casing; 3, cylinder body; 4, piston; 5, arresting disc; 6, top; 7, disk spring; 8, bearing gland; 9, bearing; 10, nut; 11, screw; 12, screw; 13, straight pin; 14, piston stroke gap; 15, gap.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2; Mill teeth machine workpiece box main shaft clamp mechanism; Comprise casing 2, be installed in workpiece box main shaft 1 on the casing, be arranged on workpiece box main shaft one end outside piston 4 and cylinder body 3 through bearing 9 that said cylinder body and piston space are located by connecting through straight pin 13, cylinder body is connected through screw 12 with casing 2 to be fixed; Two bearings 9 inner rings are through nut 10 lockings, and said bearing 9 outer rings are pressed with bearing gland 8.Through securing member arresting disc 5 is housed between said workpiece box main shaft and the piston, in the present embodiment, said securing member is preferably screw 11.Be provided with piston stroke gap 14 between said arresting disc and the piston contact-making surface, be provided with gap 15 between said arresting disc and the bearing gland contact-making surface.Be shaped on the mounting groove that is used to assemble spring and top on the said arresting disc, in the present embodiment, be shaped on three mounting grooves on the said arresting disc, the mounting groove on the said arresting disc is a circular trough, is equipped with disk spring 7 and top 6 in said each circular trough successively.
During assembling, guarantee that the arresting disc 5 and the contact-making surface of bearing gland 8 leave several gaps 15, the workpiece box main shaft loosens under the situation, and arresting disc rotates with the workpiece box main shaft and do not rub with bearing gland.During clamping work pieces case main shaft; Hydraulic system is injected hydraulic oil to cylinder body 3, and piston 4 pushes top 6 and arresting disc 5 to the right under oil liquid pressure, and strain takes place under extruding for arresting disc and bearing gland; Eliminate gap 15; Piston, arresting disc and bearing gland 8 threes compress, and arresting disc is connected through screw 11 with workpiece box main shaft 1, promptly realizes the clamping to the workpiece box main shaft.When needs loosen the workpiece box main shaft, the oil liquid pressure off-load, disk spring 7 strains resile, and promote top 6, return initial position thereby promote piston 4.Leave piston stroke gap 14 between piston and the arresting disc contact-making surface this moment, when the workpiece box main shaft rotates, avoids piston and arresting disc to rub.
