Description
Technical field
The utility model relates to a kind of pay-off of sheet material, particularly a kind of pneumatic gripping.
Background technology
In the prior art, the sheet material clamping device of the clamping plate motion of using on the numerical control press is made up of cylinder, upper clamp, lower clamp, pedestal and locking device etc.; Locking device is arranged on the pedestal, the both sides of cylinder link to each other with lower clamp through lead, lead passes described pedestal, the piston rod of piston stretches out downwards and is connected through connecting rod with upper clamp, described upper clamp and lower clamp are hinged, and the jaw that is formed for the clamping plate is opened in both ends, and the upper cover of piston rod of piston is equipped with support spring, the support spring lower end is supported on the pedestal, and the support spring upper end is supported on the bottom end cover of cylinder; Described cylinder by cylinder body, the piston in end cap and the cylinder body is formed up and down, is provided with back-moving spring between piston and the upper end cover.At present, the cylinder block of this clamping device all has steel part to make, and Heavy Weight influences the dynamic response performance of pay-off; And there is not guiding on the piston rod, the active force of clamping device clamping plate is at jaw, and the active force of piston rod is at the root of clamping device upper clamp, and piston rod is subjected to the effect of offset loading force, cause the uneven wearing and tearing of piston and cylinder wall, and cylinder block is a steel part, get rusty easily after the cylinder wall wearing and tearing, thus the wearing and tearing of aggravation sealing ring, service time is not long, cause collaborating of cylinder body upper and lower cavity, the not tight plate of clamp folder can't operate as normal.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, proposes a kind of technical scheme of pneumatic gripping, makes that the piston rod guiding of piston is good, not easy to wear, and then guarantees that the clamp clamping is reliable.
The purpose of this utility model is achieved in that a kind of pneumatic gripping, comprises cylinder, upper clamp, lower clamp, pedestal and locking device; Described locking device is arranged on the pedestal, and the lead of the both sides of cylinder through passing described pedestal links to each other with lower clamp, described cylinder by cylinder body, the piston in end cap and the cylinder body is formed up and down, is provided with back-moving spring between piston and the upper end cover; The piston rod of piston stretches out downwards and is connected through connecting rod with upper clamp, described upper clamp and the lower clamp formation jaw that is hinged, upper cover of piston rod is equipped with the support spring that is supported between pedestal and the bottom end cover, described piston rod stretches out from the two ends up and down of piston, be provided with self-lubricating bush between piston rod and the bottom end cover, the upper end cover downside is provided with the last fairlead that extends in cylinder body, described going up in the fairlead inserted in the piston rod upper end, also is provided with self-lubricating bush between last fairlead and the piston rod.
This device is fixed on it on pay-off of lathe by locking device, during the piston cavity of resorption air inlet of cylinder, it is up that the promotion piston overcomes spring force, drive an end motion of upper clamp, jaw is tightened up clamp plate, when the pay-off of lathe moves, can drive the plate motion, realize feeding; When the exhaust of piston cavity of resorption, jaw opens, and unclamps plate; When piston action, self-lubricating bush is given the enough supports of piston rod, has improved the problem that piston is subjected to offset loading force, has reduced the wearing and tearing between inboard wall of cylinder block and the piston, and to make that device uses more reliable.This device is used for Digit Control Machine Tool, can realize self-feeding.
Dependability for a progressive raising device is provided with linear bearing between described pedestal and the lead.Linear bearing has good guide effect, can guarantee that cylinder is supported by support spring after clamping plate, become quick condition, lower clamp not with workbench on steel ball produce big frictional force, during plate stamping, can fit well with the counterdie surface, not produce the distortion of clamping plate.
As further improvement of the utility model, described cylinder body, upper end cover and bottom end cover are made by aluminum alloy materials.Solved that inboard wall of cylinder block gets rusty and the clamp action that produces is ineffective, cylinder upper and lower cavity a series of problems such as collaborate, simultaneously, aluminum alloy materials density is low, in light weight, the lightweight of pneumatic gripping can improve the response performance of lathe pay-off, improves the response speed of pay-off.
