Abstract
The utility model relates to a cutting machining clamp, particularly relates to a multi-station, large-scale and automatically-clamping clamp, and more particularly relates to a tensioning mandrel attached with an axial friction force. The tensioning mandrel attached with an axial friction force comprises a pull rod, wherein the pull rod is arranged in a bearing cylinder in a penetrating manner, one end of the pull rod is connected with a pull cylinder, and the other end of the pull rod is fixed with a circular plate; a plurality of slantwise upward T-shaped grooves are formed outside the bearing cylinder, slide blocks are arranged in the T-shaped grooves respectively, the outer end surfaces of the slide blocks are arc surfaces, one end of each slide block is close to the circular plate, and the other end of each slide block is abutted against one end of a spring; and the other end of the spring is abutted against a location plate, and the location plate is sleeved on the pull rod. During use, an end surface is located with the tensioning mandrel, and the axis line of the mandrel is parallel to a workbench, thus eliminating the adverse effects of the tensioning force of the mandrel on location for the end surface, and ensuring the location and the product quality.
Description
Technical field
The utility model relates to clamp for cutting, particularly multistation, anchor clamps in enormous quantities, self-holding, especially a kind of tensioner axle that is accompanied with axial friction.
Background technology
Need the workpiece of end face and tensioner axle location in the production, for Single unit job lot production or manual, but the manual control expanding force makes the end face location good to the adverse effect of end face location.But for multistation, anchor clamps in enormous quantities, self-holding.How guaranteeing that the end face location is good, is the problem that a needs solves.
The utility model content
The purpose of this utility model is to provide a kind of tensioner axle that is accompanied with axial friction, it mainly solves the existing technical problem of above-mentioned prior art, end face and tensioner axle location, and the axle axis parallel is in workbench, eliminate the axle expanding force to the adverse effect of end face location, guarantee the location, guarantee product quality.
The utility model solves the problems of the technologies described above the technical scheme that adopts.
A kind of tensioner axle that is accompanied with axial friction, it is characterized in that: it comprises a pull bar, and this pull bar is located among the carrying cylinder, and the one end is connected with scuffing of cylinder bore, and the other end and plectane are fixed; This carrying cylinder has a plurality of T-shaped grooves obliquely outward, is respectively arranged with slide block in this T-shaped groove, and this slide block outer face is arc surface, and one end and plectane are close, and the other end then is resisted against spring one end; This spring other end is resisted against on the location-plate, and this location-plate also is set on the pull bar.
The described tensioner axle that is accompanied with axial friction is characterized in that: be fixed with feather key on the described pull bar, have the keyway corresponding to feather key in the described carrying cylinder.
The described tensioner axle that is accompanied with axial friction is characterized in that: be fixedly connected with guide finger on the described location-plate, described spring housing is located on the guide finger.
The described tensioner axle that is accompanied with axial friction is characterized in that: described T-shaped groove and slide block are provided with three, and they are equally distributed on the cylindrical same circumferential position of carrying.
Compared with prior art, the beneficial effects of the utility model are: the utility model characteristics are that the action of slide block has radial motion and axially-movable concurrently, when radial location clamps, be accompanied with axial friction workpiece and anchor clamps locating surface are well fitted.Described this positioning clamping device solves existing axle expanding force to the adverse effect of end face location.
Description of drawings
Fig. 1 is structural representation one of the present utility model (being that the A-A of Fig. 2 is to cutaway view).
Fig. 2 is structural representation two of the present utility model (being that the B-B of Fig. 1 is to cutaway view).
The specific embodiment
See also Fig. 1-2, the utility model discloses a kind of tensioner axle that is accompanied with axial friction.As shown in the figure: it comprises a pull bar 1, and this pull bar 1 is located among the carrying cylinder 5, and the one end is connected with scuffing of cylinder bore, and the other end and plectane 2 are fixing; Have a plurality of T-shaped grooves obliquely outside this carrying cylinder 5, be respectively arranged with slide block 3 in this T-shaped groove, these slide block 3 outer faces are arc surface, and one end and plectane 2 are close, and the other end then is resisted against spring 6 one ends; This spring other end is resisted against on the location-plate 8, and this location-plate 6 also is set on the pull bar 1.
As a kind of preferred structure, be fixed with feather key 4 on the described pull bar 1, have the keyway 51 corresponding to feather key 4 in the described carrying cylinder 5, do spinning movement slightly in the time of can preventing pull bar work.
As a kind of optional structure, be fixedly connected with guide finger 7 on the described location-plate 6, described spring 6 is set on the guide finger 7.
In the utility model, described T-shaped groove and slide block 3 are provided with three, and they are equally distributed on the same circumferential position of carrying cylinder 5, take this configuration example as the basis, further introduce operating position of the present utility model again.
When the utility model uses, pull bar 1 right-hand member be connected with the plunger rod of scuffing of cylinder bore, left end is fixed together plectane 2 with nut with it, and make respectively corresponding three slide blocks 3 of three screwed holes on the plectane 2, regulate the error of bringing owing to process and assemble, make arc surface energy while and the inner hole of workpiece Surface Contact of three slide blocks 3; Do spinning movement slightly when preventing pull bar 1 work, be fixed with feather key 4 at pull bar 1, in the keyway 51 of carrying cylinder 5 endoporus, slide, when pull bar moves to the right, three slide blocks 3 to the right 7 of the guide fingers in the action compresses spring 6(alternative embodiment play the spring guide effects), three slide blocks, 3 arc surfaces contacts with endoporus, and the slide block continuation is moved, tensioner radially, clamping work pieces; Simultaneously, because the axial action of slide block 3 produces axial friction between three slide blocks, 3 arc surfaces and bore area, it is good to be fitted in workpiece end face and location-plate 8 left sides, enters duty.After the completion of processing, pull bar 1 moves left, and plectane 2 breaks away from slide blocks 3, slide block 3 under the active force of spring 6 along the T-shaped groove on the cylinder 5 left below action, the circular diameter that a certain fixing point on three slide block 3 arc surfaces consists of dwindles, and breaks away from workpiece.So far, a working cycles is finished.
In sum, be preferred embodiment of the present utility model only, be not to limit practical range of the present utility model, i.e. all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
