Description

Technical Field

[0001] This utility model relates to the field of welding clamping technology, and in particular to a dual-workpiece welding clamping device. Background Technology

[0002] In the precision manufacturing of consumer electronics, assembly and welding processes place stringent requirements on the precise positioning of small and even micro-sized components. To ensure the stability of the welding process and the quality of the finished product, these tiny components often need to be suspended in mid-air to allow for welding operations from all angles.

[0003] For small workpieces with compact size that require non-concentric docking, the welding operation needs to be carried out around the component, i.e., circumferential rotation. Conventional clamping fixtures are difficult to adjust flexibly to adapt to this, and cannot ensure that the two workpieces can be accurately docked according to the preset dimensions. Often, the welding quality is acceptable in one direction, but poor welding occurs when rotating to other directions. Utility Model Content

[0004] Based on this, the present invention provides a dual-workpiece welding clamping device, which is reasonably designed and easy to use. The second clamping component adopts a multi-axis movement and flipping design. By setting the Y-axis micro head and the Z-axis micro head, fine adjustment in the Y-axis direction and the Z-axis direction can be realized respectively, so that the second workpiece can be more accurately docked with the first workpiece, thereby improving the welding accuracy and overall quality.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] Please see Figures 1 to 12This invention provides a dual-workpiece welding clamping device, comprising a first clamping component 10 and a second clamping component 20 correspondingly disposed on one side of the first clamping component 10. The first clamping component 10 clamps a first workpiece 30, and the second clamping component 20 clamps a second workpiece 40, thereby achieving a mating and abutment between the first workpiece 30 and the second workpiece 40 for welding.

[0038] The first clamping assembly 10 includes a back plate 11, a bottom support 12 movably mounted on the bottom end of the back plate 11, a lower clamping block 13 fixedly connected to the bottom support 12, a guide rod 14 slidably mounted on the top end of the back plate 11, an upper clamping block 15 mounted on the bottom end of the guide rod 14, a roller 16 rotatably mounted on the top end of the guide rod 14, a pressure cap 17 covering the top end of the guide rod 14, a lower pressure spring 18 clamped between the pressure cap 17 and the upper clamping block 15, and a rocker handle 19 rotatably connected to the pressure cap 17. The pressure cap 17 is fixedly connected to the back plate 11, and the lower pressure spring 18 drives the upper clamping block 15 to approach the lower clamping block 13. The upper clamping block 15 and the lower clamping block 13 are used to clamp the first workpiece 30.

[0039] Specifically, the guide rod 14 is slidably connected to the back plate 11 via a guide rail pair. The guide rod 14 is slidably disposed between the back plate 11 and the pressure cover 17. The top end of the rocker handle 19 is used to abut against the roller 16 to drive the guide rod 14 to move vertically upward, thereby driving the upper clamping block 15 away from the lower clamping block 13, making it convenient to take out or put in the first workpiece 30.

[0040] In this embodiment, as Figure 5 As shown, first floating springs 111 are connected to opposite sides of the bottom end of the back plate 11, and side adjusting pins 112 are screwed onto the back plate 11 corresponding to each of the first floating springs 111. The bottom support 12 is located between two first floating springs 111 and between two side adjusting pins 112. In use, by screwing the two side adjusting pins 112, the left and right positions of the bottom support 12 on the back plate 11 can be adjusted, thereby adjusting the actual position of the first workpiece 30.

[0041] The second clamping assembly 20 includes a fixed base 21, an X-axis movable seat 22 slidably connected to the top surface of the fixed base 21, a Y-axis movable seat 23 slidably connected to the top surface of the X-axis movable seat 22, a flip support 24 hinged to the front of the Y-axis movable seat 23, a Z-axis movable seat 25 slidably connected to the front of the flip support 24, and a gripper 26 rotatably mounted on the front of the Z-axis movable seat 25; the gripper 26 is used to clamp the second workpiece 40.

[0042] The X-axis movable seat 22 is slidably connected to the fixed base 21 via a guide rail pair, which is arranged along the X-axis direction. A lateral positioning plate 221 is installed on one side of the X-axis movable seat 22, and a vertical positioning plate 222 is installed on the other side. The inner walls of the lateral positioning plate 221 and the inner walls of the vertical positioning plate 222 are respectively connected to second floating springs 223. The Y-axis movable seat 23 is located between the two second floating springs 223, making the position of the Y-axis movable seat 23 adjustable.

[0043] Furthermore, a lateral spring 224 is connected between the lateral positioning plate 221 and the fixed base 21. The lateral spring 224 elastically pushes the X-axis moving seat 22 to always face the first clamping assembly 10, that is, it elastically pushes the second workpiece 40 to always face the first workpiece 30.

[0044] In this embodiment, flip support springs 225 are respectively connected to opposite sides of the front of the X-axis moving seat 22, and the flip support springs 225 are used to abut against the flip support 24.

[0045] The Y-axis moving seat 23 is slidably connected to the X-axis moving seat 22 via a first crossed roller guide 271, which is arranged along the Y-axis direction. A Y-axis micrometer head 231, arranged along the Y-axis direction, is mounted on the top surface of the Y-axis moving seat 23, with one end of the Y-axis micrometer head 231 abutting against the lateral positioning plate 221. In actual use, rotating the Y-axis micrometer head 231 can drive the Y-axis moving seat 23 to move along the Y-axis direction, achieving fine adjustment in the Y-axis direction.

[0046] Furthermore, rotating shafts 232 are connected to opposite sides of the front of the Y-axis moving base 23, and the rotating shafts 232 are used to match and connect the flip support 24.

[0047] The flip support 24 is provided with a rotating shaft insertion hole 241 on each of its opposite sides. The rotating shaft insertion hole 241 corresponds to the rotating shaft part 232, so as to realize the rotatable connection between the flip support 24 and the Y-axis moving seat 23.

[0048] The Z-axis moving seat 25 is slidably connected to the flip support 24 via a second crossed roller guide 272, which is arranged along the Z-axis direction. A Z-axis micrometer head 251, also arranged along the Z-axis direction, is mounted on one side of the Z-axis moving seat 25, with one end of the micrometer head 251 abutting against the vertical positioning plate 222. In practical use, rotating the micrometer head 251 drives the Z-axis moving seat 25 to move along the Z-axis direction, achieving fine-tuning in the Z-axis direction.

[0049] In this embodiment, as Figure 8As shown, a pivot portion 252 is connected to the bottom end of the Z-axis moving base 25. An arc-shaped groove 253 is provided on the front side of the Z-axis moving base 25 corresponding to the pivot portion 252. Both the pivot portion 252 and the groove 253 are used to connect the gripper 26. Specifically, a pivot insertion hole 261 is provided at the end of the gripper 26 near the Z-axis moving base 25, and the pivot insertion hole 261 is matched and connected to the pivot portion 252. Two locking holes 262 are also provided at intervals on the side of the gripper 26 corresponding to the pivot insertion hole 261, and the locking holes 262 are used to correspond to the groove 253. By using a locking bolt 263 to pass through the groove 253 and then screwing it into the locking hole 262, the connection and fixation between the gripper 26 and the Z-axis moving base 25 can be achieved. In actual use, the angle of the gripper 26 can be adjusted by loosening the locking bolt 263, thereby adjusting the position of the second workpiece 40.

[0050] In actual operation, the back plate 11 and the fixed base 21 are both fixedly connected to the welding flipping table. After aligning the first workpiece 30 and the second workpiece 40, they are subjected to circumferential welding to ensure that the first workpiece 30 and the second workpiece 40 can be accurately welded together.

[0051] The above-mentioned dual-workpiece welding clamping device is reasonably designed and easy to use. The second clamping component 20 adopts a multi-axis movement and flipping design. Through the setting of the Y-axis micro head 231 and the Z-axis micro head 251, fine adjustment in the Y-axis direction and Z-axis direction can be realized respectively, so that the second workpiece 40 can be more accurately docked with the first workpiece 30, thereby improving the welding accuracy and overall quality.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
