Description

Technical Field

[0001] The utility model belongs to the field of clamp welding, and more specifically relates to a tooling fixture for clamp welding. Background Art

[0002] A clamp is a tool used to fix and wrap objects, usually made of metal. Its main function is to fix objects together to prevent them from loosening or moving.

[0003] In the prior art, such as Figure 1 The clamp shown is composed of a semicircular clamp and a locking ear, and the semicircular clamp and the locking ear are connected together by welding.

[0004] However, when welding the locking ear and the semicircular clamp, the semicircular clamp and the locking ear need to be butt-jointed before welding. The semicircular clamp is irregular and inconvenient to fix, and after being butt-jointed, it will tilt during welding, resulting in the phenomenon that the locking ear is welded off-center. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a tooling fixture for clamp welding, which has the advantage of preventing the lock ear from being welded off-center due to the shaking of the semicircular clamp.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tooling jig for clamp welding comprises a base, wherein a placement groove for placing a locking ear is provided on the base, a guide column for convenient placement of the locking ear is installed in the placement groove, and auxiliary positioning components for automatically clamping a semicircular clamp are installed on both side walls of the base.

[0008] The advantages of this solution are at least as follows: first, the auxiliary positioning component is spread out, and then the semicircular clamp is placed on the base, and then the spread auxiliary positioning component is loosened to clamp the semicircular clamp, and then the locking ear is placed in the placement groove through the guidance of the guide column, and the locking ear and the semicircular clamp are pressed together by hand during welding, and then the welding work is started. The setting of the auxiliary positioning component can avoid the semicircular clamp from tilting during welding, thereby causing the locking ear to be welded off-center.

[0009] The utility model is further configured as follows: a cavity is symmetrically opened in the base, a rectangular hole communicating with the cavity is symmetrically opened in the side wall of the base, and the auxiliary positioning assembly includes: a clamping plate and a moving rod slidably installed in the cavity and the rectangular hole;

[0010] The moving rod is composed of a limit plate, a first connecting rod and a second connecting rod formed in one piece. The limit plate is slidably installed in the chamber, the first connecting rod is slidably installed in the rectangular hole, one end of the second connecting rod is fixedly connected to the clamping plate, and a plurality of return springs are installed between the inner wall of the chamber and the side wall of the limit plate.

[0011] The advantages of this scheme are at least that the elasticity of the return spring will cause the side wall of the splint to move toward the side wall of the semicircular clamp. On the one hand, it can make the side wall of the splint close to the side wall of the semicircular clamp, and on the other hand, it can reset the splint and the moving rod to their original positions when no welding work is performed. The setting of the limit plate prevents the first connecting rod from moving out of the chamber, and the limit plate, the first connecting rod and the second connecting rod are formed into a single shape, thereby increasing the structural strength of the moving rod.

[0012] The utility model is further configured as follows: a guide block is arranged on the clamping plate, an inclined surface is arranged on the guide block, and chamfers are respectively arranged on the guide blocks.

[0013] The advantages of this solution are at least that: the setting of the guide block and the inclined surface makes it unnecessary to open the splints when placing the semicircular clamp on the base. When in use, the semicircular clamp can be directly slid into the middle of the two splints through the guide block and the inclined surface, and the chamfer setting makes the semicircular clamp smoother when placed.

[0014] The utility model is further configured as follows: a silicone pad is pasted on the side wall of the clamping plate, and an anti-slip pattern is provided on the silicone pad.

[0015] The utility model is further configured as follows: mounting plates are arranged on two side walls of the base, and mounting holes are opened on the mounting plates.

[0016] The utility model is further configured as follows: an anti-slip pad is provided on the bottom surface of the base.

[0017] The advantage of this solution is at least that a hand holding groove is provided on the base, and a flexible member is provided on the inner side wall of the hand holding groove.

[0018] In summary, the utility model has at least the following advantages:

[0019] 1. By setting the placement groove, guide column and auxiliary positioning component, when docking before welding, first open the auxiliary positioning component, then place the semicircular clamp on the base, then loosen the opened auxiliary positioning component to clamp the semicircular clamp, and then place the lock ear into the placement groove through the guidance of the guide column. When welding, press the lock ear and the semicircular clamp together by hand, and then start welding. The setting of the auxiliary positioning component avoids the semicircular clamp from tilting during welding, thereby causing the lock ear to be welded off-center;

[0020] 2. By setting a return spring, the elasticity of the return spring causes the side wall of the clamping plate to move towards the side wall of the semi-circular hoop. On the one hand, it can make the side wall of the clamping plate closely adhere to the side wall of the semi-circular hoop. On the other hand, when welding work is not carried out, the clamping plate and the moving rod can be reset to their original positions. The setting of the limiting plate prevents the first connecting rod from moving out of the chamber. By integrally forming the limiting plate, the first connecting rod, and the second connecting rod, the structural strength of the moving rod is increased. By setting the guiding block and the inclined surface, the functions of the guiding block and the inclined surface are as follows: when placing the semi-circular hoop on the base, there is no need to add an action to open the clamping plate. During use, the semi-circular hoop can be directly slid between the two clamping plates through the guiding block and the inclined surface. The setting of the chamfer makes the semi-circular hoop slide in more smoothly when placed;

[0021] 3. By setting the silica gel pad and the anti-slip pad, the function of the silica gel pad is to avoid being too smooth when the side wall of the clamping plate contacts the side wall of the semi-circular hoop. The function of the anti-slip pad is to increase the friction with the bottom surface and prevent the base from moving during welding. By setting the mounting plate and the handle groove, the function of the mounting plate is to fix the base to the ground when the base needs to be fixed, and the function of the handle groove is to make it more convenient to pick up and move the base when moving the base. The function of the flexible part is to avoid the phenomenon that the hand is strangled due to the excessive weight of the base during picking up. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] A tooling fixture for hoop welding, as Figure 2 shown, includes a base 1, on which a placement groove 2 for placing the locking ear 18 is provided, a guide post 3 for facilitating the placement of the locking ear 18 is installed in the placement groove 2, and auxiliary positioning assemblies 4 for automatically clamping the semi-circular hoop 17 are installed on both side walls of the base 1;

[0031] Mounting plates 11 are provided on both side walls of the base 1, mounting holes 12 are provided on the mounting plates 11, an anti-slip pad 13 for preventing the base 1 from moving during welding is provided on the bottom surface of the base 1, a handle groove 14 is provided on the base 1, and a flexible member 15 is provided on the inner side wall of the handle groove 14. The flexible member 15 is preferably a rubber sheet in the embodiment, and may also be a flexible material such as cotton cloth or linen cloth, which will not be elaborated here.

[0032] As Figure 3 、 Figure 4 shown (refer to Figure 6 ), chambers 5 are symmetrically provided in the base 1, rectangular holes 6 communicating with the chambers 5 are symmetrically provided on the side walls of the base 1. In some embodiments, the auxiliary positioning assembly 4 includes a clamping plate 401 and a moving rod 402 slidably installed in the chambers 5 and the rectangular holes 6;

[0033] In some preferred embodiments, the moving rod 402 is composed of a limiting plate 4021, a first connecting rod 4022 and a second connecting rod 4023. It is worth noting that the limiting plate 4021, the first connecting rod 4022 and the second connecting rod 4023 are integrally formed. The limiting plate 4021 is slidably installed in the chamber 5, the first connecting rod 4022 is slidably installed in the rectangular hole 6, one end of the second connecting rod 4023 is fixedly connected to the clamping plate 401, and a plurality of return springs 7 are installed between the inner side wall of the chamber 5 and the side wall of the limiting plate 4021. It is worth mentioning that the elasticity of the return spring 7 causes the side wall of the clamping plate 401 to move towards the side wall of the semi-circular hoop 17. On the one hand, it can make the side wall of the clamping plate 401 closely adhere to the side wall of the semi-circular hoop 17, and on the other hand, it can make the clamping plate 401 and the moving rod 402 reset to their original positions when welding work is not carried out.

[0034] In order to make the clamping plate 401 clamp the semi-circular hoop 17 more tightly, in some embodiments, a silica gel pad 10 is pasted on the side wall of the clamping plate 401, and anti-slip lines are provided on the silica gel pad 10. The anti-slip lines are wavy or strip-shaped, so that when the semi-circular hoop 17 is clamped, the friction between the silica gel pad 10 and the side wall of the semi-circular hoop 17 is increased, preventing the semi-circular hoop 17 from moving during welding.

[0035] Such as Figure 5 As shown, in some embodiments, in order to facilitate the semi-circular hoop 17 to be better placed between the two clamping plates 401, a guide block 8 is provided on the clamping plate 401. An inclined surface 9 is provided on the guide block 8, and chamfers are respectively provided on the guide block 8. The semi-circular hoop 17 is better placed between the two clamping plates 401 through the inclined surface 9 on the guide block 8.

[0036] The working process and beneficial effects of the present utility model are as follows: When docking before welding, the semi-circular hoop 17 is placed on the base 1 through the guide block 8 and the inclined surface 9. Subsequently, under the action of the return spring 7, the clamping plate 401 and the silica gel pad 10 on the clamping plate 401 clamp the semi-circular hoop 17. Then, the locking ear 18 is placed in the placement groove 2 through the guiding of the guiding column 3. During welding, the locking ear 18 is pressed against the semi-circular hoop 17 by hand, and then the welding work is started. Through the setting of the auxiliary positioning assembly 4, the phenomenon that the semi-circular hoop 17 tilts during welding, resulting in the locking ear 18 being welded offset, is avoided.

[0037] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
