Abstract
The utility model relates to a clamping device of a bolt machine tool, wherein the clamping device comprises a hollow plunger piston which is installed in a hole formed at one end of a pressure plate through a spherical washer and a clamping nut; a piston is arranged in an inner hole formed on the hollow plunger piston; one end of the piston freely extends out of the bottom of the hollow plunger piston; one end of the force application screw bolt is in threaded connection with the upper opening of the hollow plunger piston; a T-head bolt, a spherical cushion block, a clamp nut and the pressure plate are fixed on a workbench of the machine tool; a workpiece and a support cylinder are arranged at two ends of the pressure plate; the bottom of the hollow plunger piston is aligned with the opening of the support cylinder; and the force application screw bolt and the piston are pushed in butter at the inner part of the support cylinder.
Description
Technical field:
The utility model relates to a kind of clamping device, and particularly a kind of bolt lathe clamping device belongs to the machine tool accessories technical field.
Background technology:
The bolt lathe generally will be fixed on workpiece above the workbench in the process of processing work.At present, the main mode that workpiece is fixed on the workbench is exactly that cushion block, backing plate are realized the clamping to workpiece to the common T type bolt of employing accordingly in addition.This clamping device in use, exist and use the defective of adjusting inconvenience, simultaneously, because the clamping force that is produced relies on the tightness decision of nut self fully, so, also there is the clamping force smaller defect, for the workpiece that can produce big strength in large-scale workpiece or the processing, have to adopt more much T type bolts to realize the purpose that clamps, therefore, also the use T type bolt of Cun Zaiing is more, unhandy defective.
The utility model content:
The purpose of this utility model is: a kind of bolt lathe clamping device is provided, this clamping device have adjust rapidly, clamping force is big, it is more to overcome the use T type bolt that inconvenience is adjusted in the existing use of existing lathe clamping device and clamping force is less and exist, unhandy defective.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: a kind of bolt lathe clamping device, it is to have a hollow plunger to be installed in the hole of pressing plate one end by spheric washer, binding nut by clamping device, in the endoporus of hollow plunger, load onto piston, one end of piston freely stretches out the bottom of hollow plunger, and application of force screw rod is installed in the position suitable for reading of hollow plunger by the threaded one end on it; T connector bolt, sphere cushion block, clamp nut, pressing plate are fixed on the workbench of lathe, and workpiece, shoring are placed on the two ends of pressing plate, and the bottom of hollow plunger and the oral area of shoring are aligned; With application of force screw rod, piston pushes in the butter of shoring inside.
Beneficial effect: the utility model utilizes the clamping of the principle realization of hydraulic coupling and lever to workpiece, have adjust rapidly, clamping force is bigger, it is more to overcome the use T type bolt that inconvenience is adjusted in the existing use of existing lathe clamping device and clamping force is less and exist effectively, unhandy defective.
Description of drawings:
Fig. 1 is a structure principle chart of the present utility model;
Shown in the figure: 1, pressing plate; 2, sphere backing plate; 3, clamp nut; 4, T type bolt; 5, application of force screw rod; 6, hollow plunger; 7, piston; 8, shoring; 9, spheric washer; 10, butter; 11, binding nut.
The specific embodiment:
Clamping device has a hollow plunger (6) to be installed in the hole of pressing plate (1) one end by spheric washer (9), binding nut (11), in the endoporus of hollow plunger (6), load onto piston (7), one end of piston (7) freely stretches out the bottom of hollow plunger (6), and application of force screw rod (5) is installed in the position suitable for reading of hollow plunger (6) by the threaded one end on it; T connector bolt (4), sphere cushion block (2), clamp nut (3), pressing plate (1) are fixed on the workbench (b) of lathe, workpiece (a), shoring (8) are placed on the two ends of pressing plate (1), and the bottom of hollow plunger (6) and the oral area of shoring (8) are aligned; With application of force screw rod (5), piston (7) pushes in the inner butter (10) of shoring (8).
Claims (2)
1. bolt lathe clamping device, it is characterized in that: hollow plunger (6) is installed in the hole of pressing plate (1) one end by spheric washer (9), binding nut (11), in the endoporus of hollow plunger (6), load onto piston (7), one end of piston (7) freely stretches out the bottom of hollow plunger (6), and application of force screw rod (5) is installed in the position suitable for reading of hollow plunger (6) by the threaded one end on it.
