Description

Locking device for hand wheel pressing nut

Technical Field

The utility model belongs to the technical field of valve body processing equipment technique and specifically relates to a locking device is pressed to hand wheel.

Background

A valve with a handwheel as a manual actuator is a common valve in industry today. The valve is opened and closed through manual rotation of a hand wheel without an external tool. The hand wheel is fixed on the valve body through a pressing nut, and the pressing nut is in threaded connection with a threaded rod on the valve body. When the hand wheel is fixed, the hand wheel is firstly sleeved on the threaded rod, and then the pressing nut and the threaded rod are screwed tightly. Because the upper end face of the gland is arc-shaped, no tool matched with the gland is used for screwing, and in addition, because the hand wheel is usually sprayed with the anti-rust paint, the anti-rust paint on the hand wheel is easily rubbed off by the aid of the screwing tool, so that the protection effect is lost. However, the problem that the pressing nut is not screwed down in place easily exists only by manual screwing of workers. Aiming at the problems in the prior art, a hand wheel nut pressing locking device is provided.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the problem among the above-mentioned prior art, provide a locking device is pressed to hand wheel, can realize through following technical scheme:

the utility model provides a locking device is pressed to hand wheel, includes the bench drill, be provided with fixed subassembly on the workstation of bench drill, the main shaft lower extreme fixedly connected with fastening head of bench drill, the lower terminal surface of fastening head set up with the extrusion hole of pressing female looks adaptation, the fastening head is made by resin material, fixed subassembly includes the fixed plate, fixed plate fixed connection is on the workstation of bench drill, the up end fixedly connected with locating plate of fixed plate, the locating plate has two and two locating plate parallel arrangement.

The utility model discloses further set up to: one sides, close to each other, of the positioning plates are fixedly connected with protection plates, and the protection plates are made of resin materials.

The utility model discloses further set up to: the utility model discloses a protection shield, including fixed plate, backup pad, threaded rod, protection shield, one end fixedly connected with location head, the up end fixedly connected with backup pad of fixed plate, the backup pad is located between two protection shields, threaded rod has in the backup pad, the axis of threaded rod is on a parallel with the length direction of protection shield, the one end fixedly connected with location head that the threaded rod is close to the protection shield, the location head is made by resin material.

The utility model discloses further set up to: one end of the threaded rod, which is far away from the protection plate, is fixedly connected with a handle with a triangular annular cross section.

The utility model discloses further set up to: and a graduated scale is marked on the upper end face of one of the positioning plates.

To sum up, the utility model discloses a beneficial technological effect does:

when the hand wheel is pressed female to lock, place the valve body between two fixed plates, the staff pushes down fastening head, it is downthehole to press female upper end to stretch into the extrusion, because fastening head and the drive of the frictional force between the pressing female press female to rotate, thereby will press female screwing up, two parallel arrangement's locating plate prevents that the valve body from rotating at the process of screwing up, because fastening head has certain elasticity, thereby when avoiding using tightening tool locking, instrument and hand wheel production rigid friction, rub the anti-rust paint on the hand wheel.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1-4, for the utility model discloses a locking device is pressed to hand wheel, including bench drill 1, be provided with fixed subassembly 2 on the workstation of bench drill 1, the main shaft lower extreme fixedly connected with fastening head 3 of bench drill 1, the lower terminal surface of fastening head 3 set up with the extrusion hole 31 of pressing female looks adaptation, fastening head 3 is made by resin material, fixed subassembly 2 includes fixed plate 21, fixed plate 21 fixed connection is on the workstation of bench drill 1, the up end fixedly connected with locating plate 22 of fixed plate 21, locating plate 22 has two and two locating plate 22 parallel arrangement, the projection of bench drill 1 main shaft axis falls in the midpoint department of two locating plate 22 length direction midpoint connection lines. When the hand wheel is pressed female to lock, place the valve body between two fixed plates 21, the staff pushes down fastening head 3, press female upper end to stretch into in the extrusion hole 31, because fastening head 3 and the drive of the frictional force between the pressing female are pressed female and are rotated, thereby will press female screwing up, two parallel arrangement's locating plate 22 prevents that the valve body from rotating at the process of screwing up, because fastening head 3 has certain elasticity, thereby when avoiding using the locking of screwing up instrument, instrument and hand wheel production rigid friction, rub the anti rust paint on the hand wheel.

A protection plate 23 is fixedly connected to a side of the positioning plate 22 adjacent to each other, and the protection plate 23 is made of a resin material. Through the setting of protection shield 23, when avoiding pressing the locking of mother, produce hard extrusion between valve body rotation and the fixed plate 21, produce the damage to the valve body surface.

The upper end face of the fixed plate 21 is fixedly connected with a supporting plate 24, the supporting plate 24 is positioned between the two protection plates 23, the supporting plate 24 is in threaded connection with a threaded rod 25, the axis of the threaded rod 25 is parallel to the length direction of the protection plates 23, one end of the threaded rod 25 close to the protection plates 23 is fixedly connected with a positioning head 26, and the positioning head 26 is made of resin materials. The position that the locating head 26 put into the valve body limits to place the valve body under fastening head 3, directly push down fastening head 3 and press female locking, thereby avoid the position of the valve body of repetition adjustment when locking.

One end of the threaded rod 25 far away from the protective plate 23 is fixedly connected with a handle 27 with a triangular ring-shaped section, and the handle 27 is convenient for rotating the threaded rod 25, so that the position of the positioning head 26 is adjusted. Wherein the upper end face of a positioning plate 22 is marked with a graduated scale 28, and the position of the positioning head 26 is conveniently determined through the graduated scale 28.
