Abstract

The utility model relates to a hand-operated machine tool clamping mechanism. A supporting cylinder is installed on a base, a piston is installed in an inner cavity of the supporting cylinder, and butter is stored in the piston; the top end of the piston is connected with a hollow plunger, and the hollow plunger is respectively provided with a spherical washer and a clamping nut; and a force application screw is installed on the top end of the hollow plunger, the force application screw is fixed through a positioning nut, a screw mechanism is installed on the top end of the force application screw, and a force application crank is installed on the screw mechanism.

Description

A kind of manual lathe clamp mechanism
Technical field
The utility model relates to a kind of clamp mechanism, and particularly a kind of manual lathe clamp mechanism, belongs to machine tool accessories technical field.
Background technology
The manual lathe of bolt of Type B, in the process of processing work, generally will be fixed on workpiece above workbench.At present, it is exactly to adopt in addition corresponding cushion block of common T-shaped bolt that workpiece is fixed on to major way on workbench, backing plate is realized the clamping to workpiece, this clamping device in use, exist to use and adjust inconvenient trouble, simultaneously, because relying on self tightness of nut completely, produced clamping force determines, so, also there is the defect that clamping force is less, for producing the workpiece of larger strength in large-scale workpiece or processing, have to adopt more much T-shaped bolts to realize the object of clamping, thereby, this has just increased the trouble of using further.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, clamping force strong, clamp rapidly, a kind of manual lathe clamp mechanism that universal performance is good, overcome the existing above-mentioned defect of existing manual lathe clamping structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of manual lathe clamp mechanism, it is comprised of screw mechanism, application of force crank, application of force screw rod, setscrew nut, hollow plunger, binding nut, spheric washer, piston, butter, shoring, base, described clamp mechanism is provided with a shoring on base, one piston is installed in the inner chamber of shoring, in piston, stores butter; On the top of piston, be connected with a hollow plunger, on hollow plunger, be respectively arranged with spheric washer and binding nut; On the top of hollow plunger, an application of force screw rod is installed, application of force screw rod is fixed by setscrew nut, on the top of application of force screw rod, a screw mechanism is installed, and application of force crank is installed on screw mechanism.
Operation principle of the present utility model is: first will utilize T connector bolt, sphere cushion block and clamp nut pressing plate to be fixed on the workbench of lathe, workpiece and shoring are placed on to the two ends of pressing plate, simultaneously, the bottom of hollow plunger and the oral area of shoring are aligned, and application of force screw rod is tightened in the utility model utilization, piston is pushed in the butter of shoring inside, thereby cause butter to expand, the butter expanding promotes hollow plunger and moves up, and utilizes lever principle, and workpiece is stepped up.
The beneficial effects of the utility model: the utility model utilizes the principle of hydraulic coupling and lever to realize the clamping to workpiece, have adjust rapidly, clamping force is larger, can effectively overcome the existing use trouble of existing machine tool clamping device and the less defect of clamping force, so, the utlity model has advantage simple in structure, that clamping force strong, clamping rapid, versatility is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present utility model is described further.
Fig. 1 is structure principle chart of the present utility model.
Shown in figure: 1, screw mechanism; 2, application of force crank; 3, application of force screw rod; 4, setscrew nut; 5, hollow plunger; 6, binding nut; 7, spheric washer; 8, piston; 9, butter; 10, shoring; 11, base.
The specific embodiment
Manually lathe clamp mechanism has a base (11), and a shoring (10) is installed on base (11), and a piston (8) is installed in the inner chamber of shoring (10), stores butter (9) in piston (8); On the top of piston (8), be connected with a hollow plunger (5), on hollow plunger (5), be respectively arranged with spheric washer (7) and binding nut (6); Top in hollow plunger (5), is provided with an application of force screw rod (3), and application of force screw rod (3) is fixing by setscrew nut (4), and the top in application of force screw rod (3), is provided with a screw mechanism (1), and application of force crank (2) is installed on screw mechanism (1).

Claims (1)
