Abstract
The utility model discloses a device for quickly pre-screwing a bolt. The device is characterized in that a driving gear is arranged in a screwing head and is matched with a driven gear; the outer end of the driven gear is connected with a screwing shaft; the driving gear is connected with a gear machine through a gear shaft; and a pneumatic screwing spanner is arranged below the gear machine. The utility model has the beneficial effects that the device is quick in screwing and can ensure the screwing-in angle; by adopting a four-shaft synchronous screwing structure, the pre-screwing speed and the assembling speed are increased; and the labor cost, the time and the force can be saved.
Description
Technical field
The utility model relates to the device for screwing up field, specifically is meant the device that tights a bolt in advance fast.
Background technology
At first can be screwed to bolt on the bolt hole in advance in the bolts assemblies process, present most of auto producer adopts manually bolt is carried out twisting in advance, its shortcoming is can't guarantee to tighten in advance the degree of depth and angle equilibrium, when tightening angle when deviation occurring, not only influence the precision when bolt being tightened, and can produce breakoff phenomenon in the double thread hole, simultaneously when manually tightening with tightening machine, waste time and energy lost labor's cost.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model provide a kind of tighten speed fast, save labour turnover, the time saving and energy saving device that tights a bolt in advance fast.
For achieving the above object, the technical solution that the utility model adopted mainly by tappet head, driving gear, driven gear, tighten axle, gear machine, pneumatic impact wrench and form; It is characterized in that: be provided with driving gear in the tappet head, driving gear cooperates with driven gear, and the driven gear outer end is connected with tightens axle, and driving gear links to each other with the gear machine by gear shaft, is provided with pneumatic impact wrench below the gear machine.
Described tighten the axle and driven gear be four.
The beneficial effects of the utility model are: tighten fast and can guarantee to be screwed into angle, adopt four and tighten structure synchronously, improved the speed of tightening in advance, improved assembling speed simultaneously, saved cost of labor, and time saving and energy saving.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
Fig. 1 Reference numeral is as follows: tappet head 1, driving gear 2, driven gear 3, tighten axle 4, gear machine 5, pneumatic impact wrench 6.
In the structure diagram of the device that tights a bolt in advance fast shown in Figure 1, its primary structure comprises: be provided with driving gear 2 in the tappet head 1, driving gear 2 cooperates with driven gear 3, driven gear 3 outer ends are connected with tightens axle 4, driving gear 2 links to each other with gear machine 5 by gear shaft, is provided with pneumatic impact wrench 6 below the gear machine 5.
Bolt is put into bolt hole, align with bolt, press pneumatic impact wrench 6 tightening axle, gear machine 5 drives driving gear 2, driving gear 2 drives four driven gears 3, makes bolt light beam part squeeze in the hole fast and be close to, and with tightening machine its threaded portion is tightened again.
