Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of water cup welding clamping device, and in particular relates to an anti-deviation clamp for welding water cups and connecting parts. Background Technology
[0002] Currently, most insulated cups on the market are vacuum insulated cups made of materials such as stainless steel or titanium. Some insulated cups have handles or other components on the cup wall, and the connection between the handles or other components and the body of the cup is mainly through a connector; this connector is usually fixed to the cup body by energy storage welding.
[0003] Energy storage welding (also known as capacitor discharge welding) has become a widely used welding technology for welded joints due to its advantages such as instantaneous high energy output, small heat-affected zone, and small welding deformation. However, the current welding fixtures do not have the function of correction, and the cup body is very easy to be misaligned during the placement of the fixture. Moreover, if there are multiple connecting pieces that need to be welded at the same time, there may be problems such as length deviations when multiple moving electrodes (upper electrodes) or multiple connecting pieces are clamped on a single moving electrode. After welding, it will not only lead to uneven welds and insufficient strength, which will seriously affect the product yield and lifespan, but also cause poor appearance (such as exposed weld points and large welds) due to the welding position deviating from the preset area, affecting the aesthetics of the product. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this utility model provides an anti-deviation clamp for welding water cups and connectors, which can automatically correct deviation and ensure accurate welding position and stable weld quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution.
[0006] An anti-deviation clamp for welding a water cup to a connector includes a cup mouth clamp and a cup bottom clamp, with the cup body clamped between the cup mouth clamp and the cup bottom clamp.

One end of the first sleeve is fixedly connected to the second flange, and the other end is rotatably connected to the second abutment member. The first abutment member and the second abutment member respectively abut against the mouth and bottom of the cup body. The cup body can adaptively rotate with the first abutment member and the second abutment member.
[0007] Preferably, both the first sleeve and the second sleeve are cylindrical structures with through holes inside; a first bearing and a second bearing are respectively sleeved on the first abutting member and the second abutting member; the first bearing and the second bearing are respectively located in the through holes of the first sleeve and the second sleeve.
[0008] Preferably, the first abutting member has a cross-shaped structure, with a first bearing rod and a support rod at its two ends, respectively, and a limiting ring protrusion between the first bearing rod and the support rod; the first bearing is sleeved on the first bearing rod; the support rod is inserted into the mouth of the cup body; and the end face of the mouth of the cup body is limited by the limiting ring protrusion.
[0009] Preferably, the second abutment has a T-shaped structure, with one end being the second bearing rod and the other end having a positioning groove that matches the shape of the bottom of the cup body; the second bearing is sleeved on the second bearing rod.
[0010] Preferably, an elastic structure is provided between the second abutment and the second sleeve, so that the second abutment has radial elastic support force.

[0012] Preferably, the elastic element is a spring, and it is set perpendicular to both the end face of the support block and the end face of the pressure block.
[0013] Preferably, both the end face of the support block and the end face of the pressure block are provided with spring holes for inserting and limiting elastic elements.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By adopting the above technical solution, the first abutting member and the second abutting member that abut against the cup body are rotatably connected to the first sleeve and the second sleeve respectively; the cup body can rotate with the first abutting member and the second abutting member; when the moving electrode presses the connecting member against the cup body, the cup body will adjust itself by rotating according to the downward pressure of the moving electrode on the two connecting members, so that the contact and pressure between the cup body and the two connecting members are balanced and adapted, thereby achieving automatic correction and ensuring accurate welding position and stable weld quality.
[0015] Further beneficial effects are: the rotation is achieved through the bearing structure, which is both stable and practical, and makes the rotation smoother.
[0016] A further beneficial effect is that by setting up an elastic element, specifically a spring, the clamping force of the fixture can be applied evenly along the contour of the cup body, absorbing the disturbance of the fixture during clamping, and further preventing problems such as uneven welds and insufficient strength caused by uneven contact force.
[0017] A further beneficial effect is that, in the elastic structure, the end faces of the support block and the pressure block are arranged parallel to each other and the spring is perpendicular to the end face, which can ensure the elastic support force for the second abutment.

The end face of the mouth of the cup body 4 is limited by the limiting ring protrusion 143. The first abutment 14 can rotate relative to the first sleeve 12 through the first bearing 13.
[0025] In one embodiment, such as Figure 4As shown, the cup bottom clamp 2 includes, from right to left, a second flange 21, a second sleeve 22, a second bearing 23, and a second abutment 24 arranged concentrically; one end of the second flange 21 is detachably connected to the welding equipment, and the other end is fixedly connected to the second sleeve 22 (in this embodiment, a bolt connection is used); the second sleeve 22 has a cylindrical structure, and the second bearing 23 is located in the through hole of the second sleeve 22; the second abutment 24 has a T-shaped structure, one end of which is the second bearing rod 241, and the end face of the other end is provided with a positioning groove 242 that matches the bottom shape of the cup body 4; the second bearing 23 is sleeved on the second bearing rod 241; the second abutment 24 can rotate relative to the second sleeve 22 through the second bearing 23; in this embodiment, the second abutment 24 serves as a static electrode (lower electrode).
[0026] With the above structural arrangement, after the cup body 4 is clamped, the support rod 142 on the first abutment member 14 of the cup mouth clamp 1 is inserted into the mouth of the cup body 4, and the end face of the mouth of the cup body 4 is limited on the limiting ring protrusion 143; the bottom of the cup body 4 is limited in the positioning groove 242 of the second abutment member 24 of the cup bottom clamp 2; the cup body 4 can then rotate with the first abutment member 14 and the second abutment member 24; when the moving electrode 3 presses the connecting member 5 onto the cup body 4 (such as... Figure 1 As shown, the cup body 4 will automatically adjust itself by rotating according to the downward pressure of the moving electrode 3 on the two connecting parts 5, so that the contact and pressure between the cup body 4 and the two connecting parts 5 are balanced and adapted, thereby achieving automatic correction and ensuring accurate welding position and stable weld quality.
[0027] In one embodiment, such as Figure 4 As shown, an elastic element 25 is also provided between the second sleeve 22 and the second abutment 24 to provide radial elastic force to the second abutment 24; specifically, the second sleeve 22 has symmetrically arranged axially outward extending support blocks 221 on the left and right sides of the end facing the second abutment 24; the second abutment 24 has correspondingly symmetrically arranged axially outward extending pressure blocks 243 on the upper and lower sides; and there is a gap between the end face of the pressure block 243 and the end face of the support block 221, and the elastic element 25 is a spring disposed in the gap; specifically, in the pressure block 243 Spring holes can also be provided on the support block 221 for positioning and installing springs; in order to facilitate the elastic support between the pressure block 243 and the support block 221, the end faces of the pressure block 243 and the support block 221 are set parallel to each other, and their end faces can be set horizontally or at an angle; through the above settings, the elastic element 25, as a flexible element, can further enable the clamping force of the fixture to be applied evenly in accordance with the contour of the cup body 4, absorb the disturbance of the fixture clamping, and further prevent problems such as uneven weld and insufficient strength caused by uneven contact force.
[0028] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model. For example, the elastic element 25 can also be disposed between the outer wall of the second abutment 24 and the inner wall of the second sleeve 22, or between the inner wall of the second abutment 24 and the outer wall of the second sleeve 22. For example, the end faces of the first bearing rod 141 of the first abutment 14 and the second bearing rod 241 of the second abutment 24 can be fixedly connected to a bearing cover 6 to restrict the first bearing 13 or the second bearing 23 from disengaging.
