[ description of reference ]
The device comprises a shell 1, a main shaft 2, a sleeve ejector rod 3, a biaxial gyroscope 4, a mounting part 5, an impact assembly 6, an impact block 61, a driven impact cylinder 62, a guide groove 63, a steel ball 64, a pressing sleeve 65 and a spring 7.
Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model discloses to current problem, a have anti-sticking resilience formula electric spanner is provided.
As shown in fig. 1, an embodiment of the present invention provides an electric wrench with anti-jamming rebound resilience, including: the casing 1, this casing 1 inside is provided with the accommodation space. A main shaft 2 is arranged in the accommodating space, and the main shaft 2 is used for connecting a transmission source such as a motor. The same setting of sleeve ejector pin 3 is in the accommodation space, and the lower extreme of sleeve ejector pin 3 stretches out shell 1, and main shaft 2 is connected with sleeve ejector pin 3 transmission, and this kind of connected mode can realize the pivoted transmission through the mode of main shaft 2 with the sleeve block.
One end of the sleeve ejector rod 3, which is far away from the main shaft 2, is provided with a double-shaft gyroscope 4, an installation part 5 is arranged on the double-shaft gyroscope 4, the installation part 5 is used for installing a screw rod, the screw rod rotates and is in relative rotation with a nut preset on a track, and the screwing effect is achieved.
In this embodiment, drive the rotation of sleeve ejector pin 3, biax gyroscope 4, installation department 5 through main shaft 2, realize the screwing to the screw rod, biax gyroscope 4 can adjust installation department 5 under the different operational environment and keep vertical state. The mounting portion 5 is kept in a vertical state, so that the situations of thread dislocation and seizure when the nut and the screw are screwed can be reduced as much as possible.
Furthermore, when the nut and the screw are still in thread dislocation and seizing during the operation of the mounting part 5, the impact assembly 6 is needed to correct the thread dislocation and seizing.
Specifically, the impact assembly 6 includes an impact block 61 and a driven impact barrel 62, the driven impact barrel 62 is disposed in the accommodating space, the lower end of the driven impact barrel 62 extends out of the housing 1, the sleeve ram 3 is disposed in the driven impact barrel 62 and extends out of the lower end of the driven impact barrel 62, the sleeve ram 3 can be engaged with the driven impact barrel 62 to realize transmission of rotation, the impact block 61 is disposed around the outer edge of the spindle 2, the outer surface of the spindle 2 is provided with a guide groove 63, the guide groove 63 is a section of spirally rising curve, a steel ball 64 is disposed in the guide groove 63, the impact block 61 can move upward along the guide groove 63 under the action of the steel ball 64, when the impact block 61 rises to the top end of the guide groove 63, the impact block 61 is separated from the steel ball 64, the impact block 61 falls under the action of gravity and impacts the driven impact barrel 62 to generate downward impact force, the impact force is transmitted to the mounting part 5 through the sleeve ejector rod 3, the screw in the mounting part 5 is vibrated for the first time, at the moment, the nut and the screw are in the conditions of thread dislocation and seizure, and the problem of wrong clamping of the screw and the nut is further corrected by adjusting the condition of thread dislocation through vibration.
In order to enhance the impact force generated by the impact block 61 when moving downwards, the impact assembly 6 further comprises a pressing sleeve 65, the pressing sleeve 65 is arranged at the upper end of the main shaft 2, the pressing sleeve 65 is arranged in the impact block 61, the outer edge of the pressing sleeve 65 is in clearance fit with the inner edge of the impact block 61, and a force for preventing the pressing sleeve 65 and the impact block 61 from approaching is arranged between the pressing sleeve 65 and the impact block 61, and the force can be realized in various conventional manners, such as an elastic element and the like. When the impact block 61 is separated, the impact block 61 has higher impact speed and impact kinetic energy compared with the action of self gravity, so that the purpose of modifying the dislocation of the threads can be better achieved. Preferably, the pressing sleeve 65 is fixedly connected with the main shaft 2.
Further, the driven impact cylinder 62 is provided with a waist-shaped groove in the vertical direction on the side wall, the sleeve ejector rod 3 is provided with an ejector rod pin at the outer edge, and the ejector rod pin is located in the waist-shaped groove and can move up and down in the waist-shaped groove. A spring 7 is provided in the driven shock tube 62, and one end of the spring 7 abuts against the main shaft 2 and the other end abuts against the socket pin 3.
In this technical scheme, the driven transmission mode who strikes a section of thick bamboo 62 and sleeve ejector pin 3 has been demonstrated, utilizes the elasticity that elasticity produced when installation department 5 is installed for the nut compresses tightly, the lock with the screw rod better, when strikeing piece 61 and striking downwards in addition, can pass through this striking of spring 7 buffering, avoids too big impact force to damage the screw thread.
The impact assembly 6 provided in the present invention is also commonly used in electric hammers and other devices, but it should be emphasized that the effect in the present application is different from that in electric hammers, the impact block 61 also provides impact force, which is used to apply acting force to the hammer head by using the impact force, increasing the kinetic energy of the hammer head, and the requirement is that the kinetic energy is larger and better; and in the utility model discloses in, impact block 61 also provides the impact force, but this is the intermediate process only, and its purpose is to revise the screw thread dislocation of bolt and nut, the condition of dying of stinging, moreover in the utility model discloses it is not required that kinetic energy is big better more, too big kinetic energy produces on the contrary with the screw thread dislocation of bolt and nut, the condition of dying become more serious, destroy the screw thread even more easily.
Thus, in the present application, the impact assembly 6 is a cross-domain transfer and does not function as well as the original domain.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
