Abstract
The invention discloses a device for detecting weld strength of piston cylinders of automobile dampers. The device comprises a base and a connecting plate which are arranged horizontally, wherein two vertical supporting plates are arranged between the base and the connecting plate; a groove for positioning a welding tube is formed above the base; a hydraulic cylinder is fixed above the connecting plate; a piston rod of the hydraulic cylinder extends below the connecting plate, the end of the piston rod is connected with a pressure head connecting disc through a nut, a pressure head is arranged below the pressure head connecting disc, and a pressure head conical surface is processed on the front end of the pressure head. The device has the beneficial effects that the weld strength of the dampers can be fast detected, and defective products can be timely identified.
Description
Technical field
The present invention relates to automobile absorber manufacturing technology field, particularly relate to a kind of auto absorber piston cylinder weld strength pick-up unit.
Background technology
In order to improve the driving comfort of automobile, in the suspension system inside of most of automobile, vibroshock is housed.The manufacturing accuracy of vibroshock and product quality directly and driving safety closely bound up, welded tube can be subject to larger stress in the process of moving, the situation that weld seam if there is welded tube occurs crackle or snaps, will cause serious consequence, and the detection like this for welded tube welding seam just seems particularly important.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of auto absorber piston cylinder weld strength pick-up unit is provided.
The technical scheme adopted for realizing object of the present invention is: a kind of auto absorber piston cylinder weld strength pick-up unit, it is characterized in that it comprises base and the web joint of horizontal positioned, be provided with two pieces of vertical back up pads between the two, described back up pad is fixedly connected with described web joint with described base;
The top of described base is fixed with positioning disk, and described positioning disk is positioned at the centre of two pieces of back up pads; The upper center place of described positioning disk is provided with the groove for positioning welding tube;
The top of described web joint is fixed with hydraulic cylinder; The piston rod of described hydraulic cylinder extends to the below of described web joint; The end of described piston rod is connected with described pressure head terminal pad by nut; The below of described pressure head terminal pad is provided with pressure head, and the front end of described pressure head is processed with the pressure head conical surface.
Described pressure head is threaded with described pressure head terminal pad.
Principle of work of the present invention is: according to the welding strength of welding seam value the preset adjustment hydraulic cylinder output pressure of welded tube.During work, open hydraulic cylinder, piston rod ejects, and band dynamic head declines, and enters in the pore of welded tube, makes welded tube produce plastic yield by the pressure head conical surface; Now check the defects the such as whether weld seam of welded tube changes, and as whether weld seam has snaps, crackle.
The invention has the beneficial effects as follows: by weld strength pick-up unit provided by the invention, can detect vibroshock welding line intensity fast, timely defective products be identified.
Accompanying drawing explanation
Figure 1 shows that the structural representation of welded tube welding seam intensity detecting device of the present invention;
Figure 2 shows that the structural representation after welded tube plastic yield.
In figure: base is 1, back up pad is 2, positioning disk is 3, groove is 4, the pressure head conical surface is 5, pressure head is 6, terminal pad is 7, nut is 8, piston rod is 9, web joint is 10, hydraulic cylinder is 11, welded tube is 12, plastic yield section is 13, weld seam is 14.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment:
A kind of auto absorber piston cylinder weld strength pick-up unit as shown in Figure 1, it comprises base 1 and the web joint 10 of horizontal positioned, be provided with two pieces of vertical back up pads 2 between the two, described back up pad 2 is fixedly connected with described web joint 10 with described base 1, show in figure, base 1, back up pad 2 and web joint 10 constitute a stable square framework, are convenient to follow-uply carry out weld seam detection operation.
Shown in Fig. 1, the top of described base 1 is fixed with positioning disk 3, and described positioning disk 3 is positioned at the centre of two pieces of back up pads 2; The upper center place of described positioning disk 3 is provided with the groove 4 for positioning welding tube 12; Groove 4 can be set to interchangeable, so that adapt to the welded tube 12 of various different size.
The top of described web joint 10 is fixed with hydraulic cylinder 11; The piston rod 9 of described hydraulic cylinder 11 extends to the below of described web joint 10; The end of described piston rod 9 is connected with described pressure head terminal pad 7 by nut 8; The below of described pressure head terminal pad 7 is provided with pressure head 6, and both are threaded, if the welded tube of different size, can be substituted by screw thread; The front end of described pressure head 6 is processed with the pressure head conical surface 5.
When operating, need first according to the welding strength of welding seam value preset adjustment hydraulic cylinder 11 output pressure of welded tube.During work, open hydraulic cylinder 11, piston rod 9 ejects, and band dynamic head 6 declines, and enters in the pore of welded tube 12, and make welded tube 12 produce plastic yield by the pressure head conical surface 5, as shown in Figure 2,13 are plastic yield section; Now check the defects the such as whether weld seam 14 of welded tube 12 changes, and as whether weld seam 14 has snaps, crackle.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
