CN201098896Y - Hexangular bolt clamping paw - Google Patents

Abstract

The utility model relates to a hexagonal screw clamping gripper, comprising a V-shaped block, a V-shaped block support, an electromagnet housing, an electromagnet shaft, a crank shaft and a stationary shaft, which is characterized in that the electromagnet shaft is arranged in the electromagnet housing; a round electromagnet is fixed in the electromagnet housing; two sliding V-shaped blocks are arranged on the V-shaped block support; the V-shaped blocks and the electromagnet shaft are respectively connected with two ends of the crank shaft through pins; the middle part of the crank shaft is positioned on the soleplate of the electromagnet housing through the stationary shaft; the whole gripper mechanism can be conveniently fixed to other mechanisms. The hexagonal screw clamping gripper is applicable to the automatic clamping of the hexagonal screw, which has the advantages of tightly screw clamping with accuracy, quickness and adaptability to different sizes, thus improving working environment and efficiency.

Description

A kind of hex head screw retaining paw

Technical field

The utility model relates to a kind of hex head screw retaining paw, belongs to the machine field of engineering technology, specifically a kind of mechanical paw with automatic clamping hex nut function.

Background technology

The machinery industry develops rapidly, hex nut is used very extensive, in many work, need a large amount of screw of dismounting, conventional method is to take clip to clamp screw, or with the spill spanner of fixed dimension, but these methods have all proposed very high requirement to the positional precision of clamper, and these clampers are all fixed for the size of operation screw, and are incompatible with the multiple size stud of same clamper clamping, thereby certain restriction has been received in its use.

Summary of the invention

At above-mentioned the deficiencies in the prior art, the utility model provides a kind of hex head screw retaining paw, and this device is pinching screw rapidly and accurately, can adapt to the operation paw of different size screw.

The purpose of this utility model is achieved through the following technical solutions:

A kind of hex head screw retaining paw, it is made up of vee-block, vee-block support, electromagnet casing, electromagnet shaft, bent axle, fixed axis, left hand crankshaft.Electromagnet shaft is placed in the electromagnet casing, be fixed with circular electromagnets in the electromagnet casing, vee-block has two slidably vee-blocks on supporting, and crankshaft two end is connected with vee-block, electromagnet shaft respectively by pin, and the bent axle middle part is positioned on the electromagnet casing base plate by fixed axis.Whole paw mechanism can be fixed on the place that needs the clamping hex screw easily.

During application, can the hexagonal retaining paw be fixed by 4 screws of electromagnet casing bottom.After the energising, about two vee-blocks can drive move left and right by two bent axles.Electromagnet shaft can step up hex screw during away from vee-block.When the bent axle rightabout moved, paw can unclamp screw.Improve work situation, raise labour productivity.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

Wherein, 1, vee-block supports, 2, vee-block, 3, electromagnet casing, 4, bent axle, 5, electromagnet shaft, 6, fixed axis, 7, pin.

The specific embodiment

Among Fig. 1, Fig. 2 and Fig. 3, electromagnet shaft 5 is placed in the electromagnet casing 3, be fixed with circular electromagnets in the electromagnet casing 3, vee-block supports on 1 two slidably vee-blocks 2, bent axle 4 two ends are connected with vee-block 2, electromagnet shaft 5 respectively by pin 7, and bent axle 4 middle parts are positioned on the electromagnet casing base plate by fixed axis 6.

During this device work, whole paw mechanism can be fixed on the place that needs the clamping hex screw easily.After the paw energising, electromagnet shaft 5 will move at hex screw paw axis direction, by 4 motions of pin 7 drive bent axles, and bent axle 4 and then drive vee-block 2, vee-block 2 can move in opposite directions or on the contrary, thus clamping or relieving hex screw.Electromagnet shaft 5 supports away from vee-block and hex screw can be stepped up in 1 o'clock.After the paw outage, when electromagnet shaft 5 rightabouts moved, paw can unclamp screw.

Claims (1)

1, a kind of hex head screw retaining paw, form by vee-block, vee-block support, electromagnet casing, electromagnet shaft, bent axle, fixed axis, it is characterized in that: electromagnet shaft is placed in the electromagnet casing, be fixed with circular electromagnets in the electromagnet casing, vee-block has two slidably vee-blocks on supporting, crankshaft two end is connected with vee-block, electromagnet shaft respectively by pin, and the bent axle middle part is positioned on the electromagnet casing base plate by fixed axis.
