Description
Technical field
The utility model belongs to clamping tool for machine work technical field, is specifically related to a kind of auto-compensation hold-down mechanism.
Background technology
In blast pipe mechanical processing process, due to process system rigidity deficiency or the existence compressing the problems such as gap, make often to occur chatter phenomenon in working angles.
The appearance of cutting chatter phenomenon damages the lifting of Machinery Processing Surface Quality, and reason is as follows:
(1) because workpiece to be processed is that each grip dimensions of black skin is all different, easily cause fixture can not by Workpiece clamping, make cutter produce vibration man-hour finished surface can be made to produce oscillation mark adding surface of the work, this will have a strong impact on the serviceability of workpiece;
(2), when cutter is relative to Workpiece vibration, cutting cross section, cutting angle, cutting force etc. all can the change of generating period, and each integral link of process system also can be affected thereupon.As cutter heavy wear, tipping occurs, and lathe connection performance is destroyed, and cutting process cannot be carried out smoothly;
(3) because the insecure dither making to occur in working angles fixed by workpiece, often along with ear-piercing sound, noise pollution over a long time brings serious harm may to the physical and mental health of operator, and the surface of processing produces vibration trace;
(4) for avoiding or reduce the generation of oscillation phenomenon, operator has to reduce cutting data sometimes, but this also can cause the service behaviour of lathe and cutter to be fully played simultaneously, thus reduces the efficiency of machining.
And in order to solve the insecure problem with long processing time of Workpiece clamping, often need workman to carry out long centering with manual fastening when reality uses, operation is extremely required great effort often to be needed to carry out fasteningly extremely expending man-hour to a workpiece for a long time, therefore needs one can very labour-saving auto-compensation hold-down mechanism.
Utility model content
The purpose of this utility model is to provide a kind of easy and simple to handle and fixing fastening auto-compensation hold-down mechanism.
Realizing the technical scheme that the purpose of this utility model adopts is: a kind of auto-compensation hold-down mechanism, comprises pneumatic mechanism, clamp body and hold-down mechanism, and described clamp body rear portion arranges pneumatic mechanism, and described pneumatic mechanism is connected with hold-down mechanism through clamp body.
Described pneumatic mechanism comprises cylinder body, cylinder connector and reversal valve, described cylinder body is arranged on clamp body rear portion, described cylinder connector is connected with cylinder body through clamp body, and described reversal valve is arranged on clamp body side, and described clamp body is connected with reversal valve with by tracheae.
Described hold-down mechanism comprises balancing pole, pressing plate, hinge, pull bar and parallels, and described balancing pole two ends are flexibly connected with pressing plate, are connected in the middle part of described pressing plate with articulate, and described hinge bottom is connected with pull bar by bearing pin, and described pressing plate bottom arranges parallels; Described parallels is arranged on clamp body.
The quantity of described parallels is two pieces or four pieces.
The quantity of described pneumatic mechanism and hold-down mechanism is two.
Described balancing pole is flexibly connected with cylinder connector.
The utility model utilizes compressed air source unit as power, changing original manual compression is pneumatic clamping, source of the gas is connected in use by reversal valve, make cylinder body control cylinder joint can be protruding, and drive balancing pole extrapolated, because pressing plate and the hinge be connected are as a fulcrum, make it can form a lever to compress, independently can revise according to the thickness of pressing plate contact surface owing to being flexibly connected between balancing pole with cylinder connector, make pressing plate fully can contact compression with pressing plate contact surface, and the parallels arranged in bottom can be good at the effect playing support, it is made to can be good at compressing, because cylinder connector inflates cylinder body under the effect of reversal valve, can control the quality compressed, blast pipe firmly compresses by four pressing plates, and milling face is subsequently operated can carry out smoothly.
The design of the utility model center platen is short and small compact, rigidity is better, and the area compressed is larger, stable thrust can be provided, ensure the stable of workpiece, make blast pipe can greatly reduce the generation of processing and trembling in process, thus effectively improve the processed surface smoothness of blast pipe; In addition, while guarantee product quality, this utility model also from reducing security incident odds to a great extent, can ensure that the efficiency of work.
