Description
Technical Field
[0001] The utility model relates to the technical field of positioning welding, in particular to a housing and a positioning welding table. Background Art
[0002] In modern industrial production, welding is a widely used connection technology. However, when welding thin-shell workpieces, a series of challenges are often faced, and the problem that thin-shell workpieces are prone to deformation is particularly prominent.
[0003] During the production process, the housing corresponding to the present application is as Figure 1 shown, including: a housing 1 and a mounting frame 2. The mounting frame 2 is mounted on the housing 1. The mounting frame 2 includes: a first mounting frame 21 and a second mounting frame 22. The first mounting frame 21 and the second mounting frame 22 are spaced along the X direction on the housing 1. The first mounting frame 21 includes: a bottom plate 211, a pair of side plates 212, a cross plate 213, and end plates 214. The bottom plate 211 is disposed on the housing 1. The pair of side plates 212 are spaced on the bottom plate 211. The cross plate 213 is disposed between the pair of side plates 212. Both end portions of the cross plate 213 are respectively abutted against the corresponding side plates 212. The end plates 214 are disposed on the bottom plate 211. Both end portions of the pair of side plates 212 on the side away from the second mounting frame 22 are abutted against the side surfaces of the end plates 214. A set of positioning holes 10 are provided on the housing 1. A set of positioning protrusions 23 adapted to the set of positioning holes 10 are provided at the bottom of the mounting frame 2. The set of positioning holes 10 are used to accommodate the set of positioning protrusions 23. For such a housing, due to its own structural characteristics, it usually has a large surface area to thickness ratio. This special structure makes them extremely sensitive to heat input during the welding process. When the welding heat source acts on the surface of the housing, the local area will quickly heat up, resulting in thermal expansion of the material. Since the stiffness of the housing is relatively low, it cannot effectively resist the stress caused by this thermal expansion, thus easily causing deformation and resulting in damage to the housing. Summary of the Utility Model
[0004] To overcome the deficiencies of the above-mentioned prior art, the utility model provides a positioning welding table, which solves the technical problem that the housing will be deformed when heated during the welding process.
[0005] To achieve the above object, the utility model is realized by the following technical solutions:
[0006] A housing, comprising: a housing body and a mounting bracket. The mounting bracket is mounted on the housing body.

As a preferred solution of the present application, the first positioning protrusion in a housing of the present application is used for limiting the first mounting bracket in the X and Y directions when the first mounting bracket is mounted on the housing body.
[0008] Further, in a housing of the present application, a limiting protrusion is provided at the bottom of the end plate, and a limiting notch corresponding to the limiting protrusion is provided on the bottom plate. The limiting protrusion is disposed in the limiting notch. As a preferred solution of the present application, the first positioning protrusion in a housing of the present application is used for limiting the first mounting bracket in the X and Y directions when the first mounting bracket is mounted on the housing body.
[0009] A positioning welding table for positioning a housing before welding, comprising: a base plate, a set of positioning brackets, and a locking and limiting member. The housing body is disposed on the base plate. The set of positioning brackets are spaced apart along the X direction on the base plate. The edge of the housing body abuts against the side surfaces of the set of positioning brackets in the Y direction. A first notch is provided on the base plate, and the first notch is disposed opposite to the set of positioning brackets. A first convex portion corresponding to the first notch is provided on the housing body. The side surface of the first convex portion abuts against the side wall of the first notch in the X direction. The locking and limiting member is mounted on the upper end of the positioning bracket, and the locking and limiting member is used for locking and limiting the housing body, the first mounting bracket, and the second mounting bracket together on the base plate in the Z direction.
[0010] Based on the above structure, the principle of the positioning welding table is as follows: first, the shell is placed on the base plate, the outer edge of the shell is in conflict with the side of a group of positioning frames, a group of positioning frames are used to limit the shell in the Y direction, the first convex portion is placed in the first notch, and the side of the first convex portion is in conflict with the side wall of the first notch in the X direction, forming a limit in the X direction for the shell, and then the first mounting frame and the second mounting frame are installed on the shell in sequence, a group of positioning convexities are respectively inserted into the corresponding positioning holes, and then the locking and limiting components are opened, and the shell and the first mounting frame and the second mounting frame are locked and limited on the base plate to form a limit in the Z direction, completing the positioning of the cover before welding.
[0011] Further, a positioning and welding table in the present application, the locking and limiting component includes: a first connecting rod, a second connecting rod, a third connecting rod, a base, a pressing part, and a positioning pressing part. The base is installed on the positioning frame. The first connecting rod is arranged on the base, and the base is pivotally connected to the first connecting rod. The pressing part is installed at one end of the first connecting rod away from the base. The second connecting rod is arranged at the upper end of the base, and the second connecting rod is pivotally connected to the first connecting rod. The third connecting rod is arranged between the second connecting rod and the base, and both ends of the third connecting rod are pivotally connected to the second connecting rod and the base respectively. The positioning pressing part includes: a first positioning pressing part and a second positioning pressing part. The positioning pressing part is arranged on the housing. The first positioning pressing part is arranged on the bottom plate, and the first positioning pressing part is arranged between a pair of first mounting brackets. Both end parts of the first positioning pressing part are in contact with the sides of the cross plate and the end plate respectively in the X direction. The second positioning pressing part is arranged on the housing, and the second positioning pressing part is arranged between the first mounting bracket and the second mounting bracket. Both end parts of the first positioning pressing part are in contact with the sides of the cross plate and the second mounting bracket respectively in the X direction. When the locking and limiting component is in the locked state, the end part of the pressing part presses on the positioning pressing part, and in the Z direction, the housing, the first mounting bracket, and the second mounting bracket are locked and limited on the base plate together. The connecting pivot between the first connecting rod and the second connecting rod, the connecting pivot between the second connecting rod and the third connecting rod, and the connecting pivot between the third connecting rod and the base are collinear. As a preferred solution of the present application, the locking and limiting component in a positioning and welding table of the present application is used to lock and limit the housing, the first mounting bracket, and the second mounting bracket on the base plate together in the Z direction. When the locking and limiting component releases the lock on the housing, the first mounting bracket, and the second mounting bracket in the Z direction, the second connecting rod is toggled, and the second connecting rod rotates away from the base around the pivot between the second connecting rod and the first connecting rod. Since the first connecting rod is pivotally connected to the base and both ends of the third connecting rod are pivotally connected to the second connecting rod and the base respectively, under the drive of the second connecting rod, the first connecting rod rotates away from the positioning pressing part around the pivot between the first connecting rod and the base, and the third connecting rod rotates away from the base around the pivot between the third connecting rod and the base. During this process in the Z direction, the rotating pivot between the second connecting rod and the third connecting rod moves upward relative to the pivot between the second connecting rod and the first connecting rod, and the rotating pivot between the first connecting rod and the second connecting rod moves downward relative to the rotating pivot between the second connecting rod and the third connecting rod, thereby driving the lower end surface of the pressing part to separate from the upper end surface of the positioning pressing part and releasing the lock;
[0012] When the locking and limiting component needs to lock the housing, the first mounting bracket, and the second mounting bracket in the Z direction, the second connecting rod is toggled. The second connecting rod rotates towards the base direction around the pivot between the second connecting rod and the first connecting rod. Since the first connecting rod is pivotally connected to the base and both ends of the third connecting rod are pivotally connected to the second connecting rod and the base respectively, under the drive of the second connecting rod, the first connecting rod rotates towards the direction close to the positioning pressing member around the pivot between the first connecting rod and the base, and the third connecting rod rotates towards the base direction around the pivot between the third connecting rod and the base. During this process in the Z direction, the pivot between the second connecting rod and the third connecting rod moves downward relative to the pivot between the second connecting rod and the first connecting rod, and the pivot between the first connecting rod and the second connecting rod moves upward relative to the pivot between the second connecting rod and the third connecting rod. When the connecting pivot between the first connecting rod and the second connecting rod, the connecting pivot between the second connecting rod and the third connecting rod, and the connecting pivot between the third connecting rod and the base are collinear, the lower end surface of the pressing portion fits with the upper end surface of the positioning pressing member to complete the locking; the pressing portion can be movably adjusted and connected in the extending direction of the first connecting rod, which is convenient for the pressing portion to abut against different positions on the positioning pressing member.
[0013] Further, in a positioning and welding table of the present application, the locking and limiting component further includes: a positioning beam, which is erected on a pair of side plates. The positioning beam includes a pair of stoppers, and the pair of stoppers are arranged at intervals at the lower end of the positioning beam. The pair of side plates are located between the pair of stoppers, and the outer side surfaces of the pair of side plates are respectively correspondingly attached to the inner side surfaces of the pair of stoppers in the Y direction. As a preferred solution of the present application, the positioning beam in a positioning and welding table of the present application is used for limiting the pair of side plates in the Y direction, and during the welding process, it ensures that the pair of side plates do not undergo thermal deformation.
[0014] Further, in a positioning and welding table of the present application, it further includes: a limiting convex portion, which is arranged on the base plate, and the limiting convex portion is arranged on the same side as a group of positioning brackets. As a preferred solution of the present application, the limiting convex portion in a housing of the present application cooperates with a group of positioning brackets to limit the housing in the Y direction.
[0015] Further, in a positioning and welding table of the present application, a group of support plates are arranged in an array along the Y direction on the bottom surface of the base plate, and the group of support plates are arranged along the extending direction of the base plate. As a preferred solution of the present application, the support plates in a housing of the present application are used to enhance the ability of the base plate to resist deformation, prevent the positioning and welding table from deforming during use, and extend the service life of the positioning and welding table.
[0016] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:
[0017] The utility model provides a positioning welding table. A set of positioning frames arranged on the positioning welding table limit the cover shell in the Y direction, the workpiece is limited in the X direction through the first notch, and the cover shell is locked and limited on the base plate through the locking and limiting component.

[0030] Based on the above structure, the principle of the positioning welding table is as follows: First, place the housing 1 on the base plate 3. The outer edge of the housing 1 abuts against the side surfaces of a set of the positioning frames 4. A set of the positioning frames 4 are used to limit the housing 1 in the Y direction. The first convex portion 11 is placed into the first notch 31, and the side surface of the first convex portion 11 abuts against the side wall of the first notch 31 in the X direction to form a limit for the housing 1 in the X direction. Then, install the first mounting frame 21 and the second mounting frame 22 on the housing 1 in sequence, and a set of positioning protrusions 23 are respectively inserted into the corresponding positioning holes 10. Next, open the locking and limiting component 5 to lock and limit the housing 1, the first mounting frame 21, and the second mounting frame 22 on the base plate 3 to form a limit in the Z direction, thus completing the positioning before welding the housing. A set of the positioning frames 4 includes 3 positioning frames 4.
[0031] Such as Figure 5 、 6As shown in the figure, in this embodiment, the locking and limiting member 5 includes: a first link 51, a second link 52, a third link 53, a base 54, a pressing portion 55, and a positioning pressing member 56. The base 54 is installed on the positioning frame 4. The first link 51 is arranged on the base 54, and the base 54 is pivotally connected to the first link 51. The pressing portion 55 is installed at one end of the first link 51 away from the base 54. The second link 52 is arranged at the upper end of the base 54, and the second link 52 is pivotally connected to the first link 51. The third link 53 is arranged between the second link 52 and the base 54, and both ends of the third link 53 are pivotally connected to the second link 52 and the base 54 respectively. The positioning pressing member 56 includes: a first positioning pressing member 561 and a second positioning pressing member 562. The positioning pressing member 56 is arranged on the housing 1. The first positioning pressing member 561 is arranged on the bottom plate 211, and the first positioning pressing member 561 is arranged between a pair of first mounting brackets 21. The two side ends of the first positioning pressing member 561 are respectively in contact with the side surfaces of the cross plate 213 and the end plate 214 in the X direction. The second positioning pressing member 562 is arranged on the housing 1, and the second positioning pressing member 562 is arranged between the first mounting bracket 21 and the second mounting bracket 22. The two side ends of the first positioning pressing member 561 are respectively in contact with the side surfaces of the cross plate 213 and the second mounting bracket 22 in the X direction. When the locking and limiting member 5 is in the locked state, the end of the pressing portion 55 presses against the positioning pressing member 56, and in the Z direction, the housing 1, the first mounting bracket 21, and the second mounting bracket 22 are locked and limited together on the base plate 3. The connecting pivot between the first link 51 and the second link 52, the connecting pivot between the second link 52 and the third link 53, and the connecting pivot between the third link 53 and the base 54 are collinear. The locking and limiting member 5 is used to lock and limit the housing 1, the first mounting bracket 21, and the second mounting bracket 22 together on the base plate 3 in the Z direction. When the locking and limiting member 5 releases the lock on the housing 1, the first mounting bracket 21, and the second mounting bracket 22 in the Z direction, the second link 52 is toggled, and the second link 52 rotates away from the base 54 around the pivot between the second link 52 and the first link 51. Since the first link 51 is pivotally connected to the base 54 and both ends of the third link 53 are pivotally connected to the second link 52 and the base 54 respectively, under the drive of the second link 52, the first link 51 rotates away from the positioning pressing member 56 around the pivot between the first link 51 and the base 54, and the third link 53 rotates away from the base 54 around the pivot between the third link 53 and the base 54.

The second connecting rod 52 rotates around the pivot between the second connecting rod 52 and the first connecting rod 51 towards the base 54. Since the first connecting rod 51 is pivotally connected to the base 54 and both ends of the third connecting rod 53 are pivotally connected to the second connecting rod 52 and the base 54 respectively, under the drive of the second connecting rod 52, the first connecting rod 51 rotates around the pivot between the first connecting rod 51 and the base 54 towards the positioning pressing member 56, and the third connecting rod 53 rotates around the pivot between the third connecting rod 53 and the base 54 towards the base 54.

When the connecting pivot between the first connecting rod 51 and the second connecting rod 52, the connecting pivot between the second connecting rod 52 and the third connecting rod 53, and the connecting pivot between the third connecting rod 53 and the base 54 are collinear, the lower end surface of the pressing portion 55 fits against the upper end surface of the positioning pressing member 56 to complete the locking; the pressing portion 55 can be movably and adjustably connected in the extending direction of the first connecting rod 51, facilitating the pressing portion 55 to abut against different positions on the positioning pressing member 56.
