Abstract
The invention relates to a nut locking device for a press machine. The nut locking device for the press machine comprises a cylinder body (1) and a piston (2) arranged in the cylinder body (1), the piston (2) can move along the cylinder body (1), the upper end of the piston (2) is connected with a tensioning screw (3), the lower end of the tensioning screw (3) is connected with a nut (4), and the upper part of the nut (4) is limited by the cylinder body (1). The nut locking device for the press machine has the following advantages that 1), the nut is locked through the movement of the piston according to the hydraulic drive principle, the structure is simple, and the locking efficiency is high; 2), in order to achieve universality, the upper end of the tensioning screw is set into the same model, so as to fulfill the purpose of universality.
Description
Technical field
The present invention relates to a kind of forcing press nut locking device, belong to forcing press locking technical field.
Background technology
Now at large tonnage pressing machine, big nut on split machine body drag bar all needs locking, and locking device has multiple, but mostly there is inefficiency, baroque defect, and existing locking device often can only be locked for the forcing press of a certain model, each other can not be general.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide that a kind of structure is simple, operating efficiency is high, and has the forcing press nut locking device of versatility.
The technical solution used in the present invention is for this reason: the present invention includes cylinder body (1) and be arranged on the piston (2) in cylinder body (1), piston (2) can move along cylinder body (1), piston (2) upper end connects stretching screw (3), stretching screw (3) lower end attaching nut (4), nut (4) top is spacing by cylinder body (1).
Establish oily passage between cylinder body (1) and piston (2), between cylinder body (1) and piston (2), establish pressure-resistant seal circle (5).
Be threaded connection between described piston (2) and stretching screw (1).
Advantage of the present invention is: 1) the present invention is by hydraulic-driven principle, is realized the locking of nut by the motion of piston, and its structure is simple, and locking efficiency is high;
2) the present invention is in order to realize versatility, same model can be arranged in stretching screw upper end, reach the object of versatility with this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 be cylinder body, 2 be piston in figure, 3 be stretching screw, 4 be nut, 5 for pressure-resistant seal circle.
Detailed description of the invention
The piston 2 that the present invention includes cylinder body 1 and be arranged in cylinder body 1, piston 2 can move along cylinder body 1, and piston 2 upper end connects stretching screw 3, and stretching screw 3 lower end attaching nut 4, nut 4 top is spacing by cylinder body 1.
Establish oily passage between cylinder body 1 and piston 2, between cylinder body 1 and piston 2, establish pressure-resistant seal circle 5.
Be threaded connection between described piston 2 and stretching screw 1.
The course of work of the present invention is: first pass into pressure oil toward piston 2, and piston 2 moves upward under the effect of pressure oil, and the present invention is arranged circumferentially pressure-resistant seal circle 5 at piston 2, the object of leaking to prevent pressure oil; Piston 2 moves upward and then drives stretching screw 3 to move upward, and then drives nut 4 to move upward; As shown in the figure, nut 4, by cylinder body 1 lower end dieback, realizes locking.
The screw thread of same model is arranged in junction between stretching screw 3 upper end of the present invention and piston 2, possessing versatility.
What the connected mode between stretching screw 3 of the present invention and piston 2 was certain can adopt other forms of connected mode, and this connected mode can be arranged to same model, to possess versatility.
Power source of the present invention can be pressure oil, can certainly be gases at high pressure, can realize adjustment as its pressure size by the valve of peripheral hardware, and can arrange Pressure gauge and shown.
Oily passage of the present invention and gas passage can arrange several, with the pressure uniform making each portion of piston 2 be subject to, realize steadily moving upward of piston 2.
Claims (3)
1. forcing press nut locking device, it is characterized in that, comprise cylinder body (1) and be arranged on the piston (2) in cylinder body (1), piston (2) can move along cylinder body (1), piston (2) upper end connects stretching screw (3), stretching screw (3) lower end attaching nut (4), nut (4) top is spacing by cylinder body (1).
2. forcing press nut locking device according to claim 1, is characterized in that, establishes oily passage between cylinder body (1) and piston (2), establishes pressure-resistant seal circle (5) between cylinder body (1) and piston (2).
