Abstract

Disclosed is a self-supply reaction torque electric tool. A reaction torque sleeve is sleeved on an electric tool. The electric tool is in fit with the reaction torque sleeve through a key groove. An outer sleeve is sleeved on the outer side of the reaction torque sleeve. The outer sleeve and the reaction torque sleeve can rotate relatively. A push rod is arranged at the tail end of the electric tool. The push and the electric tool can rotate relatively. The push rod extends out through the reaction torque sleeve and the outer sleeve.

Description

Confession reaction torque electric tool

Technical field

A kind of confession reaction torque electric tool is used for slowing down even the reaction torque demand when eliminating work.

Background technology

In the current construction of carrying out the operations such as electric drill, electric hammer, water brill at various needs, because the reaction torque demand during itself rotation causes friction aggravation between drill bit and the hole wall, reduced the service life of drill bit, increased energy consumption, and labour intensity increases during manually-operated, has reduced security.

Summary of the invention

A kind ofly can confess the reaction torque electric tool, compare the handle that does not have the side with the conventional electric instrument, there is keyway the electric tool side, and reaction torque sleeve of overcoat is built on the reaction torque sleeve lining, cooperate with the keyway of electric tool side, the outside cover of reaction torque sleeve has an outer sleeve, and outer sleeve is connected with self-locking bearing by rolling bearing, and the tail end of electric tool is equipped with a push rod, can relatively rotate between push rod and electric tool, push rod stretches out by reaction torque sleeve and outer sleeve; Described electric tool is a kind of during electric drill, electric hammer, water bore; Described reaction torque barrel forward end has the zigzag projection; The key of described reaction torque sleeve lining is a kind of in vertical key, the screw thread key, and during for vertical key, the direction of key be the axis direction along the electric tool rotation; Described outer sleeve length is not more than the reaction torque length sleeve; Connect by rolling bearing between described outer sleeve and the reaction torque sleeve, the quantity of bearing is at least 1; Described push rod fills an end and links to each other with the tail end of electric tool, and the other end passes the reaction torque sleeve and outer sleeve leaks in the outside, and can rotate.

During use, to confess that reaction torque electric tool integral body presses and the scope of operation, make the front end of reaction torque sleeve have the part of zigzag projection and the scope of operation to combine closely, then starting electric tool and promoting push rod advances electric tool, this moment, the reaction torque sleeve provided reaction torque with frictional force or the engagement force that the scope of operation directly contacts for electric tool, and making only needs to promote electric tool when operating and do not need manually to provide reaction torque that it is stablized; When the key in the reaction torque sleeve was the screw thread key, electric tool itself was owing to providing reaction torque without external force, and meeting and drill bit rotate together, the direction of rotating is identical, promote electric tool and advance by the guide effect of the screw thread key of reaction torque sleeve lining this moment, makes electric tool automatically finish effect.

Use the advantage of confession reaction torque electric tool to be, need not manually to provide reaction torque, make the electric tool working stability, improve the service life of drill bit, labour intensity when having reduced manually-operated, increase security, and can carry out automated job with connecting other plant equipment easily, improved efficiency of construction.

Description of drawings

Fig. 1 is the structural representation of straight spline confession reaction torque electric tool.

Fig. 2 is the structural representation of screw thread key confession reaction torque electric tool.

According to shown in Figure 1,1. electric tool, it is a kind of during electric drill, electric hammer, water bore, 2. is the reaction torque sleeve, 3. is the key on the reaction torque sleeve lining, 4. is outer sleeve, 5. is rolling bearing, 6. is push rod.Can see, when the key of reaction torque sleeve lining is the screw thread key, 6. push rod can be installed.

According to shown in Figure 2,1. electric tool, it is a kind of during electric drill, electric hammer, water bore, 2. is the reaction torque sleeve, 3. being the key on the reaction torque sleeve lining, 4. is outer sleeve, 5. is rolling bearing, can see, when the key of reaction torque sleeve lining is the screw thread key, 6. push rod can be installed.

This figure only as a kind of typical example, does not limit its form, such as the number of the position of key and keyway, rolling bearing, push rod length etc.

The implementation form

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is set forth

A kind ofly can confess the reaction torque electric tool, compare the handle that does not have the side with the conventional electric instrument, 1. there is keyway the electric tool side, one in overcoat is the reaction torque sleeve 2., build on the reaction torque sleeve lining, cooperate with the keyway of electric tool side, 2. the outside of reaction torque sleeve cover has a 4. outer sleeve, 4. outer sleeve is connected with self-locking bearing by 5. rolling bearing, 1. the tail end of electric tool is equipped with a 6. push rod, can relatively rotate between push rod and electric tool, 6. push rod by 2. reaction torque sleeve and 4. outer sleeve stretch out; Described 1. electric tool is a kind of during electric drill, electric hammer, water bore; Described 2. reaction torque barrel forward end has the zigzag projection; The key of described 3. reaction torque sleeve lining is a kind of in vertical key, the screw thread key, and during for vertical key, the direction of key be the axis direction along the electric tool rotation; Described outer sleeve length is not more than the reaction torque length sleeve; Described 4. outer sleeve and 2. connecting by 5. rolling bearing between the reaction torque sleeve, the quantity of bearing is at least 1; Described 6. push rod fills an end and links to each other with the 1. tail end of electric tool, the other end pass 2. the reaction torque sleeve and 4. outer sleeve leak in the outside, and can rotate.

The present embodiment only as a kind of typical form of implementation of the present utility model, does not limit its other forms of implementation.
