Description

Large-scale pneumatic spanner external member

Technical field

The utility model relates to engine assembling field, particularly a kind of large-scale pneumatic spanner external member.

Background technology

Pneumatic wrench (Impact wrench) is a pneumatic tool of tightening or unscrew bolt, nut, and being also referred to as is ratchet wrench and electric tool aggregate, mainly is the instrument that a kind of consumption with minimum provides high moment of torsion output.It lets an object with certain mass quicken rotation through the power source that continues, and moment hits force-output shaft then, thereby can obtain bigger moment output.Compressed air is modal power source, but also has use electronic or hydraulic pressure.At present, pneumatic wrench is used commonplace in the production assembling industry of enterprise, no matter be simple post operation, and still complicated streamline assembling.

When using pneumatic wrench to work; Pneumatic wrench can produce one with screw moment of torsion in the opposite direction, needs the user to hold pneumatic wrench tight in one's hands and come this moment of torsion of balance, but moving this torque ratio of existing pneumatic wrench is bigger; Particularly large-scale hand-operated pneumatic spanner weight is heavier, this moment of torsion is bigger; Depend alone and hold pneumatic wrench tight in one's hands and be difficult to offset, long-time use also cause easily both hands can be numb, ache, production efficiency reduces.In addition, when using pneumatic wrench, need press the switch of pneumatic wrench when holding tight in one's hands, the pneumatic wrench that is unfavorable for more holding with a firm grip comes this moment of torsion of balance always.

The utility model content

The technical problem that the utility model solves provides a kind of large-scale pneumatic spanner external member of can the pneumatic wrench moment of torsion of balance, enhancing productivity.

For achieving the above object, according to the utility model a kind of large-scale pneumatic spanner external member is provided, comprising: fastening framework, handle and stabiliser bar; Fastening framework has the spanner installing hole that axially runs through, and the periphery of spanner installing hole is evenly equipped with and the adaptive screw of the fastening screw of pneumatic impact spanner housing; Stabiliser bar vertically is provided with, and an end is fixed on the end face of fastening framework, and the other end is connected on the balancer of pneumatic impact spanner; Handle is shaft-like, and an end is fixed on fastening frame facet.

Further, the orthogonal setting of handle and stabiliser bar.

Further, be provided with reinforcement between handle and the stabiliser bar.

Further, the upper end of stabiliser bar has suspension ring, and is connected on the balancer of pneumatic impact spanner through suspension ring.

Further, an end of handle is fixed on fastening frame facet through the first support fixation plate; The lower end of stabiliser bar is fixed on the end face of fastening framework through the second support fixation plate.

According to the technical scheme of the utility model, because the leverage of this large-scale pneumatic spanner external member through handle increases the hold moment of torsion of user to pneumatic impact spanner, reduced the working strength of the operation torque of balance pneumatic impact spanner, improved production efficiency; Simultaneously, control the switch of pneumatic impact spanner, make that the user needn't component control, reduced the working strength of the operation torque of balance pneumatic impact spanner equally, improved production efficiency through rubber band.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.

Referring to Fig. 1 and Fig. 2, this large-scale pneumatic spanner external member comprises: fastening framework 1, handle 2 and stabiliser bar 3.Wherein, Fastening framework 1 square tubulose has the spanner installing hole 11 that axially runs through, and four jiaos of square end surface are respectively arranged with screw 12; When using this large-scale pneumatic spanner external member; Pneumatic impact spanner penetrates the spanner installing hole 11 of fastening framework 1, and carries out fasteningly through the screw 12 that bolt passes fastening screw of pneumatic impact spanner housing and fastening framework 1, and this large-scale pneumatic spanner external member is fixed on the pneumatic impact spanner.

Handle 2 is shaft-like, and left end is a handle, and right-hand member is fixed on the left surface of square tubulose fastening frame frame 1 through rectangle support fixation plate 21, and support fixation plate 21 is welded on the fastening framework 1.

Stabiliser bar 3 is shaft-like; The lower end is fixed on the end face of square tubulose fastening frame frame 1 through rectangle support fixation plate 31; The upper end has suspension ring 32; The steel wire rope that is used to replace to hang originally pneumatic impact spanner is connected to the balancer of pneumatic impact spanner, because stabiliser bar 3 is shaft-like, more can offset the moment of torsion of pneumatic impact spanner than steel wire rope.

Handle 2 and stabiliser bar 3 orthogonal settings are welded with shaft-like reinforcement 4 between the two.

During use; As shown in Figure 3; Earlier pneumatic impact spanner 5 is penetrated the spanner installing hole 11 of the fastening framework 1 of this large-scale pneumatic spanner external member 6; And carry out fasteningly through the screw 12 that bolt passes fastening screw of pneumatic impact spanner housing and fastening framework 1, this large-scale pneumatic spanner external member 6 is fixed on the pneumatic impact spanner 5; The suspension ring 32 of the stabiliser bar 3 through this large-scale pneumatic spanner external member 6 are fixed to (balancer 7 is lifted on the slide rail 8) on the pneumatic impact spanner balancer 7 with pneumatic impact spanner 5 then, make pneumatic impact spanner 5 be positioned at the upturned position top of a side of assembling turning trolley 10 on the streamline.The suspension height of pneumatic impact spanner 5 and balance dynamics; Can realize through the elastic force size of the balancer 7 of connection above the adjusting; The suspension height of pneumatic impact spanner 5 is higher than the height of assembling turning trolley 10 on the streamline, just pull down turning trolley usefulness when assembling turning trolley 10 needs upset on the streamline, is suspended on the top of dolly 10 when not working through the elastic force of balancer 7; The size of equilibrant force will with pneumatic impact spanner 5 can be through balancer 7 elastic force can height capable of expansion and contraction, the dynamics size to fit.At this moment; The switch of pneumatic impact spanner 5 is connected on the stabiliser bar 3 through rubber band 9; Utilize the elasticity of rubber band 9 that the switch pull-up is opened, user's a handgrip is lived the handle of pneumatic impact spanner 5, and the handle 2 that another is held tight this large-scale pneumatic spanner external member 6 is screwed work.

Because this large-scale pneumatic spanner external member 6 increases the hold moment of torsion of user to pneumatic impact spanner 5 through the leverage of handle 2, has reduced the working strength of the operation torque of balance pneumatic impact spanner 5, has improved production efficiency; Simultaneously, control the switch of pneumatic impact spanner 5, make that the user needn't component control, reduced the working strength of the operation torque of balance pneumatic impact spanner 5 equally, improved production efficiency through rubber band 9.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
