Abstract
The utility model relates to a kind of novel pull-rod nut locking device in injection moulding machine clamping mechanism; this device for do counterbore on pull-rod nut; after pull-rod nut and pull bar are fixed; again pull-rod nut cover plate is screwed on pull bar; sink to the counterbore of pull-rod nut, and with screw, pull-rod nut cover plate and pull-rod nut are fixed, make the screw thread stress deformation on pull bar and pull-rod nut cover plate; pull-rod nut cover plate can not rotate, and pull-rod nut also can not be rotated and reach anti-loosing effect with this.The method installation and removal facilitate and have good outward appearance, have good value for applications.
Description
Technical field
The utility model relates to a kind of novel pull-rod nut locking device of injection moulding machine.
Background technology
The pull-rod nut locking device of existing injection moulding machine is after pull-rod nut screws in pull bar, a cover plate is increased again at end face, depart from center at pull bar end face and open screw, hole opened by cover plate, at pull bar through after injection moulding machine solid plate, after pull-rod nut and pull bar are fixing with screw by pull bar and cover plate, cover plate and solid plate are fixed respectively, and by stoping pull bar to rotate locking, the method screw number uses more, difficulty is installed, and unsightly.
Summary of the invention
The purpose of this utility model makes the anti-loosing effect of pull-rod nut better, and can easy accessibility, good looking appearance.
Goal of the invention of the present utility model is mainly achieved by following technical proposals: do counterbore design in pull-rod nut end, and open screwed hole on counterbore step surface.The thickness of pull-rod nut cover plate is less than the counterbore degree of depth of pull-rod nut, opens the screw counter bore corresponding with pull-rod nut upper screwed hole at the end face of pull-rod nut cover plate, opens symmetrical unthreaded hole for rotating rod nut cover plate at the end face of pull-rod nut cover plate.After pull-rod nut and pull bar are fixed, pull-rod nut cover plate is screwed on pull bar again, rotation to pull-rod nut cover plate sinks to the counterbore of pull-rod nut, ensure that there is certain gap in the counterbore face of pull-rod nut cover plate and pull-rod nut, use screw-driving again after aiming at screw, make the screw thread stress deformation on pull bar and pull-rod nut cover plate, pull-rod nut cover plate is stoped to rotate, because pull-rod nut cover plate is connected with pull-rod nut screw, so pull-rod nut would not rotate, reach anti-loosing effect.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Drawing is labeled as: (1)-pull bar, (2)-pull-rod nut, (3)-pull-rod nut cover plate, (4)-screw.
Fig. 2 is sectional view of the present utility model.
Drawing is labeled as: (1)-pull bar, (2)-pull-rod nut, (3)-pull-rod nut cover plate, (4)-screw.
Detailed description of the invention
As shown in Fig. 1, Fig. 2, do counterbore design in the end of pull-rod nut (2), and on counterbore step surface, open 2 symmetrical screwed holes.The thickness of pull-rod nut cover plate (3) is less than the counterbore degree of depth of pull-rod nut (2), open the screw counter bore corresponding with pull-rod nut (2) upper screwed hole at the end face of pull-rod nut cover plate (3), open symmetrical unthreaded hole for rotating rod nut cover plate (3) at the end face of pull-rod nut cover plate (3).After pull-rod nut (2) is fixing with pull bar (1), pull-rod nut cover plate (3) is screwed in again on pull bar (1), rotation to pull-rod nut cover plate (3) sinks to the counterbore of pull-rod nut (2), ensure there is gap between pull-rod nut cover plate (3) and pull-rod nut (2), screw (4) is used to tighten again after aiming at screw, make the screw thread stress deformation on pull bar (1) and pull-rod nut cover plate (3), pull-rod nut cover plate (3) is stoped to rotate, because pull-rod nut cover plate (3) is connected with pull-rod nut (2) screw (4), so pull-rod nut (2) would not rotate, reach anti-loosing effect.
Claims (1)
1. a novel pull-rod nut locking device, it is characterized in that: do counterbore design in the end of pull-rod nut (2), and on counterbore step surface, open 2 symmetrical screwed holes, the thickness of pull-rod nut cover plate (3) is less than the counterbore degree of depth of pull-rod nut (2), the screw counter bore corresponding with pull-rod nut (2) upper screwed hole is opened at the end face of pull-rod nut cover plate (3), symmetrical unthreaded hole is opened for rotating rod nut cover plate (3) at the end face of pull-rod nut cover plate (3), after pull-rod nut (2) is fixing with pull bar (1), pull-rod nut cover plate (3) is screwed in again on pull bar (1), rotation to pull-rod nut cover plate (3) sinks to the counterbore of pull-rod nut (2), ensure there is gap between pull-rod nut cover plate (3) and pull-rod nut (2), screw (4) is used to tighten again after aiming at screw, make the screw thread stress deformation on pull bar (1) and pull-rod nut cover plate (3), pull-rod nut cover plate (3) is stoped to rotate, because pull-rod nut cover plate (3) is connected with pull-rod nut (2) screw (4), so pull-rod nut (2) would not rotate, reach anti-loosing effect.
