Abstract
An expander for detection of an automobile punching part comprises a connecting arm (9) and a hydraulic cylinder (1), wherein one end of the hydraulic cylinder (1) is connected with the connecting arm (9), the other side at the upper end of a jaw (10) is connected with a plunger (6) through a connecting block (12), a check ring (8) is fixed on the jaw (10), a protective jacket (11) is positioned at the front end of the jaw (10), the check ring (8) is positioned between the protective jacket (11) and a clamp arm (7), and a front protective plate (3) is arranged between a limit block (2) and the jaw (10). The expander solves a series of problems of low production efficiency, easy mechanical deformation, breakage and the like caused by manual operation in the absent of special tools. By means of the expander, the operation for separating welding assemblies is time-saving and labor-saving, the structure is simple, operation is easy, the production efficiency is high, risks of mechanical deformation, breakage, personal safety and the like caused by manual operation are avoided.
Description
Technical field
The utility model relates to a kind of detection expander, belongs to the machine tool field.In particular, it is that a kind of stamping parts of automobile detects expander.
Background technology
In the manufacturing of auto parts and components is produced, for purposes such as detection and dismounting, often need to be with two very firmly mechanical parts that connected separately.The existing separately method of mechanical part that generally adopts is: manually chisel with instruments such as hammers.When concrete enforcement operation, use not only force limited of manual operations, waste time and energy, there is certain potential safety hazard, and easily causes the deformation and fracture of machinery.Therefore be badly in need of a kind of simple to operate, volume is little, be easy to carry, labour intensity is low and efficient is high novel detection expansion tool.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of stamping parts of automobile to detect expander.It is a kind of simple to operate, novel detection expander that efficient is high and safe and reliable.
the purpose of this utility model reaches by following measure: stamping parts of automobile detects expander, it is characterized in that it comprises linking arm, hydraulic cylinder, one end of described hydraulic cylinder is connected with described linking arm, the other end of described hydraulic cylinder is connected with connecting plate, plunger is positioned at connecting plate, limited block is fixed on described hydraulic cylinder, apron plate is fixed on described connecting plate, upper end one side of jaw is hinged by pin and described connecting plate, the upper end opposite side of described jaw is connected by contiguous block with described plunger, back-up ring is fixed on described jaw, there is sheath to be positioned at the front end of described jaw, described back-up ring is between described sheath and tong arm, described apron plate is between described limited block and described jaw.
In technique scheme, described pin, tong arm, back-up ring, jaw, sheath, contiguous block respectively have two.
The utlity model has following advantage: the series of problems that the manually-operated that it has solved does not have specific purpose tool brings provides a kind of novel stamping parts of automobile to detect expander.It adopts the mode of external connection power device, and active force is large, has reduced labour intensity, has improved operating efficiency.And its easy operating simple in structure has avoided manual behaviour to do distortion, fracture and the personal security equivalent risk of the machinery that brings.
Description of drawings
Fig. 1 is the structural representation of the utility model closure state.
Fig. 2 is the structural representation of the utility model open mode.
In figure 1, hydraulic cylinder, 2, limited block, 3, apron plate, 4, connecting plate, 5, pin, 6, plunger, 7, tong arm, 8, back-up ring, 9, linking arm, 10, jaw, 11, sheath, 12, contiguous block.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but it does not consist of to restriction of the present utility model, only for example.By explanation, advantage of the present utility model will become more clear and easily understand simultaneously.
consult Fig. 1, 2 as can be known: stamping parts of automobile detects expander, it is characterized in that it comprises linking arm 9, hydraulic cylinder 1, one end of described hydraulic cylinder 1 is connected with described linking arm 9, the other end of described hydraulic cylinder 1 is connected with connecting plate 4, plunger 6 is positioned at connecting plate 4, limited block 2 is fixed on described hydraulic cylinder 1, apron plate 3 is fixed on described connecting plate 4, upper end one side of jaw 10 is hinged by pin 5 and described connecting plate 4, the upper end opposite side of described jaw 10 is connected by contiguous block 12 with described plunger 6, back-up ring 8 is fixed on described jaw 10, there is sheath 11 to be positioned at the front end of described jaw 10, described back-up ring 8 is between described sheath 11 and tong arm 7, described apron plate 3 is between described limited block 2 and described jaw 10.Described pin 5, tong arm 7, back-up ring 8, jaw 10, sheath 11, contiguous block 12 respectively have two.
The utility model course of work is: linking arm 9 is connected with external power set, and external power set drive hydraulic cylinders 1 work by linking arm 9, and limited block 2 regulator solution cylinder pressures 1 move the stroke that moves to connecting plate 4.The front end of the jaw 10 of closure is inserted the junction of welding assembly, when turn limited block 2 left, under the thrust of hydraulic pressure, hydraulic cylinder 1 is to 4 li movements of connecting plate, the plunger 6 that promotes 4 li of connecting plates travels forward, because a side of jaw 10 upper ends is hinged by pin 5 and connecting plate 4, the opposite side of the upper end of jaw 10 is connected with plunger 6 by contiguous block 12, travelling forward of plunger 6 promotes 10 expansions of two jaws, continue left-handed limited block 2, can be so that hydraulic cylinder 1 move to maximum displacement place of connecting plate 4, thus realize the separately purpose of welding assembly; When dextrorotation limited block 2, under the pulling force effect of hydraulic pressure, hydraulic cylinder 1 pulls the plunger 6 of 4 li of connecting plates to move backward to the outer movement of connecting plate 4, thereby pulls two jaws 10 to shrink.
Apron plate 3 is fixed on connecting plate 4, is the device of protection operator safety.
Tong arm 7 is the part of jaw 10 thickenings, for strengthening the device of jaw 10 holding capacity.
Back-up ring 8 can be controlled the insertion depth of jaw 10.
Sheath 11 can protect the tip of jaw 10 to get rusty or wear and tear.
Other is prior art without the part that describes in detail.
