Abstract
The utility model discloses an automatic workpiece clamping mechanism of a machine tool. The mechanism comprises a clamping base (1) fixedly connected with a power head, the center of the clamping base (1) is provided with a center hole (6), the end face of the clamping base (1) can be rotatably provided with at least three eccentric clamping blocks (2) which are distributed circumferentially with the center hole (6) as a circle center, and when the clamping base (1) rotates and works, the eccentric clamping blocks (2) clamp workpieces (7) under the action of centrifugal force; each eccentric clamping block (2) is provided with an arc-shaped positioning groove (4) used for limiting the machining diameter range of the workpieces, and the clamping base (1) is correspondingly and fixedly provided with positioning pins (5) matched with the arc-shaped positioning grooves (4); when the clamping base (1) does not rotate or work, the maximum machining diameter limiting end of the arc-shaped positioning groove (4) of each eccentric clamping block (2) abuts against the corresponding positioning pin (5) under the action of the gravity center. By means of the structure, the automatic workpiece clamping mechanism has the advantages of being simple and reasonable in structure, convenient to produce and machine, high in work efficiency, safe and reliable to use, capable of facilitating grinding automation and the like.
Description
Technical field
Clamp mechanism when the utility model relates to a kind of lathe class rotating machined workpiece, particularly Automatic-clamping workpiece when a kind of lathe class rotary work, the clamp mechanism of automatically unclamping workpiece while quitting work.
Background technology
As everyone knows, lathe class rotating machined workpiece adopts three-jaw flange form binding clasp mostly, by hand workpiece is packed in fixture and clamped, then with cutter, workpiece is carried out to machining, this manual mode relatively wastes time and energy, and inefficiency can not adapt to the requirement of workpiece processing in enormous quantities, and easily make workpiece clamp askew when neophyty operation, affect the machining accuracy of operation below.Now also there is the device that adopts frame for movement to realize Automatic-clamping workpiece, although operating efficiency is greatly improved, in use exist following weak point: the one, complex structure, fixture requirement on machining accuracy is high, and fixture cost is large.The 2nd, clamping force regulates inconvenient, is prone to the problem because of work positioning gauge cun large the caused insufficient clamping force of error, causes the not clamped and accident that produces of workpiece.For this reason, many manufacturers and knowledgeable people have carried out development, but not yet have so far comparatively ideal product to emerge.
Summary of the invention
The above-mentioned defect existing for overcoming existing Machinetool workpiece clamp mechanism, the purpose of this utility model be to provide a kind of simple and reasonable, production and processing convenient, operating efficiency is high, safe and reliable, conveniently realize the Machinetool workpiece automatic clamping mechanism of car mill process automation.
The utility model solves the problems of the technologies described above adopted technical scheme, it comprises the clamping seats being fixedly connected with unit head, the center of described clamping seats is provided with centre bore, the end face of clamping seats is provided with at least three rotationally take centre bore as the center of circle and the eccentric clamping piece of circumference uniform distribution, eccentric clamping piece clamping work pieces under centrifugal action when clamping seats rotation work.
Further scheme of the present utility model, every described eccentric clamping piece is provided with the arc positioning groove that limits workpiece processing diameter range, the corresponding alignment pin matching with arc positioning groove that is fixed with on clamping seats, clamping seats is not when rotation work, and the maximum machining diameter of every eccentric clamping piece its arc positioning groove under center of gravity effect limits end and leans against on alignment pin.
Adopt after said structure, compared with prior art have the following advantages and effect.
The one, due to three or more eccentric clamping piece being installed on clamping seats, the centrifugal force clamping work pieces that while utilizing clamping seats rotation, eccentric clamping piece produces, can be according to shape and the size of the shape of workpiece and size adjustment eccentric clamping piece, Workpiece clamping is simple and convenient, solid and reliable, has greatly improved workpiece installation rate.
The 2nd, because rotary speed is faster, the angle that eccentric clamping piece rotates is larger, and the centrifugal force of generation is also larger, clamping work pieces is just more firm, guarantee that workpiece process safety is reliable, and can realize workpiece centre and automatically locate, avoid the inaccurate mismachining tolerance driving of traditional machine tool centre bore.
The 3rd, the arc positioning groove on eccentric clamping piece coordinates with the alignment pin on clamping seats, not only can limit the processing diameter of workpiece, and can in the time that quitting work, clamping seats guarantee that eccentric clamping piece is in clamping maximum diameter of workpiece position, be convenient to workpiece mounting or dismounting, can avoid exceeding design speed time, eccentric clamping piece exceedes design runlength and the lathe that causes damages simultaneously.The 4th,, the utility model is mainly used in the in batches workpiece of rotation processing, realizes by coordinating with automatic nutriment mechanism the full-automation that lathe, grinding machine are processed.

The specific embodiment
Shown in Fig. 1 to Fig. 4, for the specific embodiments of a kind of Machinetool workpiece automatic clamping mechanism of the utility model, it comprises the clamping seats 1 being fixedly connected with unit head, the center of described clamping seats 1 is provided with centre bore 6, centre bore 6 is more preferably greater than workpiece 7 diameters, can facilitate the installation of workpiece 7, the end face of clamping seats 1 is provided with three take centre bore 6 as the center of circle and the eccentric clamping piece 2 of circumference uniform distribution rotationally by stepped screw 3, three eccentric clamping pieces 2 require weight identical, shape is consistent, the centrifugal force producing while guaranteeing rotary work equates, in the time of clamping seats 1 rotation work, three eccentric clamping pieces 2 produce identical centrifugal force from three angles clamping work pieces 7 simultaneously under clamping seats 1 drives, guarantee workpiece 7 automatic accurate location, center, can not produce the inaccurate mismachining tolerance of bringing in location.
Fig. 2 and Figure 3 shows that structural representation when the utility model is processed maximum workpiece 7 diameter, now, arc positioning groove 4 maximum machining diameters that the alignment pin 5 on clamping seats 1 leans against eccentric clamping piece 2 limit on end.
Figure 4 shows that structural representation when the utility model is processed minimum workpiece 7 diameter, now, arc positioning groove 4 minimum machining diameters that the alignment pin 5 on clamping seats 1 leans against eccentric clamping piece 2 limit on end.
The above; just specific embodiment of the utility model, not makes any pro forma restriction to utility model, is not departing from the technical solution of the utility model basis; simple modification, equivalent variations or the modification done, all fall into protection domain of the present utility model.
