Problems solved by technology

The impact wrench with single-head output can only tighten one torque bolt at a time. For the piercing clamp that needs to be clamped by two bolts, the two bolts cannot be tightened at the same time. Tightening the two bolts separately will cause the insulation piercing clamp to be damaged. The insulating shell is tilted, twisted, and stuck
The distance between the two output heads of the impact wrench with double-head output is fixed, which cannot meet the installation requirements of different types of insulation piercing clamps, and only one impact motor provides power for the two output ends at the same time, and there is insufficient torque to torque the bolts and nuts smoothly. twisted problem

Embodiment 1

[0036] see figure 1 and figure 2 , a double-head impact screwdriver device, including a base 1, two impact wrenches 2, a slide 4, a lead screw 5, and an adjustment device 3. The lead screw 5 is rotatably connected in the base 1, and two slide plates 4 are threaded on the lead screw 5, and an impact wrench 2 is installed on the top of each slide plate 4, and the power output ends of the two impact wrench 2 are located on the same side of the base 1 , and are fixedly connected with the sleeve 8. The sleeve 8 is used to connect the impact wrench 2 to the bolt to be tightened, and the shape of its inner hole is determined according to the shape of the head of the torque bolt it acts on.

[0037] Such as image 3 As shown, the impact wrench 2 includes a housing 25, an impact motor 29 installed in the housing 25, a reducer 26, an impact head 21, a driven bevel gear 23 and a driving bevel gear 24 respectively rotatably connected in the housing 25. The impact head 21 adopts the s...

Embodiment 2

[0044] see Figure 6 The difference between this embodiment and Embodiment 1 is that: only one end of the lead screw 5 is provided with a threaded section, and a slide plate 4 is threadedly connected to the threaded section, and the top surface of the base 1 is fixedly installed with a slide plate 4- The fixed plate 9 on the side, the top of the sliding plate 4 and the fixed plate 9 are respectively equipped with an impact wrench 2 . The power output ends of the two impact wrenches 2 are located on the same side of the base 1 , and both are fixedly connected with a sleeve 8 . Other features are the same as in Embodiment 1.

[0045] In this embodiment, the adjusting device 3 drives the lead screw 5 to rotate, and under the action of screw transmission, the slide plate 4 on the lead screw 5 and the impact wrench 2 on the top of the slide plate 4 move horizontally, approaching or away from the impact on the fixed plate 9 Wrench 2, so as to realize the distance adjustment betwee...

Abstract

The invention discloses a double-head impact screwdriver device. The double-head impact screwdriver device comprises a base, two impact wrenches, sliding plates, a lead screw and an adjusting device,wherein the lead screw is rotationally connected into the base, one end of the lead screw is movably connected with the adjusting device, the lead screw is in threaded connection with one/two slidingplates, the tops of the sliding plates are provided with the impact wrenches, and the power output ends of the impact wrenches are fixedly connected with sleeves. According to the double-head impact screwdriver device, by adjusting the distance between the two impact wrenches, two torque bolts can be tightened and twisted off at the same time, the installation requirements of puncture wire clampsof different models can be met, and the adaptability and practicability are good; and the two impact wrenches are adopted to carry out tightening operation on the two torque bolts on the puncture wireclamps respectively, each impact wrench is independently provided with an impact motor and is driven by a speed reducer and a bevel gear pair, so that enough large output torque is guaranteed, and the twisting process of the torque bolts is smoother.

Description

technical field [0001] The invention relates to the technical field of electric construction tooling, in particular to a double-head impact screwdriver device. Background technique [0002] During the maintenance and construction of the distribution circuit, when the cable needs to be branched or connected, the insulation piercing clamp is usually used to complete the installation of the cable branch. The insulation piercing clamp has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. It can be used as a cable branch without cutting off the main cable or stripping the insulation layer of the cable. The joint is completely insulated and can be used for live work. On-site branching does not require the use of terminal boxes and junction boxes, and the joints are resistant to twisting, shockproof, waterproof, and anti-corrosion and aging. The comprehensive benefits are obvious, and the cost performance is better than the traditional co...
