Abstract
The utility model discloses a chisel and relates to the field of automobile welding spot intensity detection technology. The chisel comprises a chisel head and a chisel handle, wherein a support structure is also arranged between the chisel head and the chisel handle, and the support structure protrudes from the chisel to the direction deviated from the chisel head. The chisel disclosed by the utility model is suitable for the automobile welding production line and can be applied to the welding spot intensity detection of resistance type spot welding of various kinds, and in addition, the detection is convenient.
Description
Technical field
The utility model relates to automobile pad intensity detection technical field, relates in particular to a kind of chisel.
Background technology
In automobile industry, automotive bobdy sheet metal welding spot-welding technology is quite general at present, and the detection of butt welding point intensity is absolutely necessary behind the welded body.Resistance-type spot welding is as the main welding manner of automobile industry, convenient welding, and beautiful appearance, but the detection method of Joint Strength is comparatively single, thus cause the little or solder joint of vehicle body nugget to snap, finally cause because the potential safety hazard that weld strength causes.Traditional resistance-type spot welding point strength detecting method is faced chisel directly for use and on the solder joint after the automobile body welding, is carried out elimination test; Because the solder joint of appearance component position and curved portion is difficult for rejecting; Can't carry out elimination test to the part solder joint, this causes and big hidden danger for the car load weld strength.

The technical problem that the utility model will solve is: a kind of chisel that is suitable for all kinds of resistance-type weld nugget intensity detection is provided.
(2) technical scheme
For addressing the above problem, the utility model provides a kind of chisel, and this chisel comprises cutter head and cutter handle, also is provided with supporting construction between said cutter head and the said cutter handle, and said supporting construction is outstanding to the direction that deviates from said cutter head from said cutter handle.
Preferably, said supporting construction is circular arc.
Preferably, said cutter head is perpendicular to said cutter handle.
Preferably, said cutter head is wedge shape or taper away from an end of said supporting construction.
Preferably, said cutter handle is wedge shape or taper away from an end of said supporting construction.
Preferably, said cutter head and/or cutter handle are cuboid, cylinder or prism.
Preferably, said cutter head, cutter handle and supporting construction are by 60Si
2The Mn steel is processed, and HRC is 45-50.
Preferably, said cutter head, cutter handle and supporting construction are integrally formed.
(3) beneficial effect
The chisel of the utility model is applicable to automotive welding production line, can be applicable to all kinds of resistance-type weld nugget intensity detection, and easy to detect.
Description of drawings
Fig. 1 is the structural representation according to the chisel of one embodiment of the present invention;
Fig. 2 (a) is the structural representation of the chisel of embodiment 1;
Fig. 2 (b) is the side view of the chisel of embodiment 1;
Fig. 3 is the structural representation of the chisel of embodiment 2.
The specific embodiment
The chisel that the utility model proposes specifies as follows in conjunction with accompanying drawing and embodiment.
In order to solve resistance-type weld nugget strong detected intensity problem; Better controlled car load weld strength problem; This is practical to provide a kind of new testing tool; Profile and angle with himself are deep into it in flaggy of solder joint periphery through hammer, detect through simple sled, form such as break off with the fingers and thumb again, and the testing of Joint Strength is normally carried out aborning.
As shown in Figure 1, comprise cutter 1 and cutter handle 2 according to the chisel of a kind of embodiment of the utility model, also be provided with supporting construction 3 between cutter 1 and the cutter handle 2, supporting construction 3 is given prominence to the direction that deviates from cutter 1 from cutting a hole handle 2.Chisel with this embodiment after welding is deep in the flaggy of solder joint periphery; Through being fulcrum with supporting construction 3; Form such as can simply prize, break off with the fingers and thumb, thereby whole sheet material around the solder joint levered up greater than certain angle, solder joint self does not have cracking, and to be regarded as solder joint qualified.
In the chisel of present embodiment mode, supporting construction 3 is circular arc.Cutter 1 is perpendicular to cutter handle 2.Cutter 1 end away from supporting construction 3 is wedge shape or taper.Cutter handle 2 also can be wedge shape or taper away from an end of supporting construction 3, only can carry out with cutting a hole handle 2 during solder joint at the detection plane position, is similar to tradition and faces chisel directly.Cutter 1 and/or cutter handle 2 can be cuboid, cylinder or prism.
In the chisel of the utility model, supporting construction 3 can be the additional structure that is independent of cutter 1 and cutter handle 2, and perhaps integrally formed with cutter 1 and cutter handle 2, this is the mature technology of this area, as the restriction to the utility model technical scheme.The size of cutter 1, cutter handle 2 and supporting construction 3 also can be set according to concrete technological requirement, at this also not as restriction to the utility model technical scheme.In the chisel of present embodiment, cutter 1, cutter handle 2 and supporting construction 3 are integrally formed, cutter 1 axle perpendicular to cutter handle 2; Shown in Fig. 2 (a); The length L 1 of cutter 1 is 30mm, and supporting construction 3 is an arc, and its chord length L2 is 80mm; Cutter handle 2 and supporting construction 3 are 280mm along the entire length L3 of footstalk 2, cutter 1 along its axially to the distance L 4 of the minimum point of supporting construction 3 be 42mm.The end of cutter 1 is wedge shape, its section long respectively 10mm of leg-of-mutton two vertical edges and 6mm.The end of cutter handle 2 also is wedge shape, its section long respectively 40mm of leg-of-mutton two vertical edges and 6mm.Shown in Fig. 2 (b), when chisel kept flat, its thickness H was 20mm.The chisel integral body that possesses the present embodiment of above-mentioned parameter can lever up sheet material around the solder joint greater than 30 degree, and it is qualified that solder joint self nothing cracking is regarded as solder joint.
In the chisel of present embodiment; Cutter 1, cutter handle 2 and supporting construction 3 are integrally formed; Cutter 1 is perpendicular to the axle of cutter handle 2, and is as shown in Figure 3, and the length L 1 of cutter 1 is 30mm; Cutter handle 2 and supporting construction 3 are 220mm along the entire length L2 of footstalk 2, cutter 1 along its axially to the distance L 4 of the minimum point of supporting construction 3 be 42mm.The end of cutter 1 is wedge shape, and different with embodiment 1 is that the ascent direction of its wedge shape is opposite, its section long respectively 10mm of leg-of-mutton two vertical edges and 6mm.The end of cutter handle 2 also is wedge shape, its section long respectively 40mm of leg-of-mutton two vertical edges and 6mm.When chisel kept flat, its thickness was 20mm.The chisel integral body that possesses the present embodiment of above-mentioned parameter can lever up sheet material around the solder joint greater than 30 degree, and it is qualified that solder joint self nothing cracking is regarded as solder joint.
Above embodiment only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be defined by the claims.
