Detailed Description of the Embodiments

[0019] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0020] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the accompanying drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0021] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0022] Please refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides a dust cover welding tooling, which includes a base 100 and a cover body positioning component 200, a rod positioning component 300, and a pushing component arranged on the base 100.

[0023] Specifically, the base 100 can be a plate-like structure of any shape to carry other components. The cover body positioning component 200 is used to limit the cover body to be welded so that the welded cover body can be horizontally placed on the base 100 and will not shift during welding. The rod positioning component 300 is used to limit the rod to be welded so that the rod to be welded and the cover body to be welded are in a weldable state.

[0024] That is to say, by the cooperation of the cover body positioning component 200 and the rod positioning component 300, the relative position and posture between the rod to be welded and the cover body to be welded can be adjusted, so that welding can be performed.

[0025] When the cover body to be welded is limited on the base 100 by the cover body positioning component 200, the pushing component is inside the cover body to be welded. The pushing component includes a pushing member 410 and a driving unit 420. The pushing member 410 can extend or retract in the horizontal direction under the drive of the driving unit 420. When the pushing member 410 is in the extended state, the pushing member 410 can abut against the rod to be welded from the inside to the outside of the weld joint of the cover body to be welded, preventing the rod to be welded from shifting and being overly inserted into the inside of the cover body to be welded at the weld joint during welding, thereby maintaining the relative fixation between the cover body to be welded and the rod to be welded.

[0026] In some embodiments of the present utility model, the pushing member 410 includes a push rod 411 and a push plate 412 that are perpendicular to each other. The push plate 412 is disposed along a vertical plane and is connected to one end of the push rod 411 away from the driving unit 420. The push rod 411 is disposed along a horizontal direction, and the other end thereof is connected to the driving unit 420. Thus, through the arrangement of the push plate 412, it can cooperate with the end of the member to be welded, prevent the member to be welded from rotating due to abutment, and further ensure the welding effect.

[0027] Please refer to Figure 1 and Figure 2 , in some embodiments, the driving unit 420 includes a fixed seat 421, a holding rod 422, and a connecting rod 423. Specifically, the fixed seat 421 is disposed on the base 100, and the holding rod 422 is hinged to the fixed seat 421 so as to be able to rotate relative to the fixed seat 421. Two ends of the connecting rod 423 are respectively hinged to the holding rod 422 and the end of the push rod 411. Thus, when the holding rod 422 rotates due to an external force, it can drive the push rod 411 to extend or retract through the connecting rod 423.

[0028] During actual use, after the housing to be welded and the member to be welded are placed, the operator can pull down the holding rod 422. Due to the arrangement of the connecting rod 423, the rotation of the holding rod 422 can be converted into a horizontal linear motion of the pushing member 410, so that the pushing member 410 extends along the horizontal direction and then abuts against the end of the member to be welded, maintaining the relative fixation between the member to be welded and the housing to be welded. Then, after welding is completed, the operator can pull up the holding rod 422, and the pushing member 410 retracts under the action of the connecting rod 423, releasing the abutment with the member to be welded to facilitate the blanking of the finished product.

[0029] Please refer to Figure 2 , in some embodiments of the present utility model, a first bending portion is provided on the holding rod 422. The end of the connecting rod 423 is hinged to the first bending portion, and the opening direction of the first bending portion faces away from the connecting rod 423. In addition, a second bending portion is provided on the connecting rod 423, and the opening direction of the second bending portion is downward. Based on the arrangements of the first bending portion and the second bending portion, when the holding rod 422 pulls the pushing member 410 through the connecting rod 423, damage to the hinge joints of the three can be reduced, making the movement of the pushing member 410 smoother.

[0030] In one example, to ensure the smooth movement of the push rod 411, the number of the connecting rods 423 can be two. The two connecting rods 423 are arranged in parallel and coaxially hinged to both sides of the holding rod 422. Similarly, the other ends of the two connecting rods 423 are also coaxially hinged to both sides of the push rod 411.

[0031] In some embodiments, a guide cylinder 424 is further provided on the fixed seat 421. The guide cylinder 424 is arranged in the horizontal direction, and the ejector rod 411 passes through the guide cylinder 424 and is connected to the push plate 412. Thus, when the ejector rod 411 moves in the horizontal direction, the guide cylinder 424 can play a guiding role to prevent the ejector rod 411 from deviating from the horizontal state due to external forces, ensuring the abutting effect on the members to be welded.

[0032] In some embodiments of the present utility model, the cover positioning member includes at least one positioning block, and the positioning block is adapted to a positioning groove on the outer surface of the cover to be welded. Thus, when limiting the cover to be welded, it is only necessary to align and fit the positioning groove of the cover to be welded with the positioning block. Further, to ensure the limiting effect on the cover to be welded, the number of positioning blocks can be multiple, for example, two.

[0033] In some embodiments of the present utility model, the member positioning assembly can include a first limiting member 310 and a second limiting member 320. The top of the first limiting member 310 has an inclined surface, and the shape of the inclined surface is adapted to the shape of the member to be welded, so as to be able to partially wrap the outer surface of the member to be welded. The inclined surface slopes upward in the direction close to the top-pushing assembly. It should be noted that the inclination angle of the inclined surface can be set according to actual needs. The second limiting member 320 is arranged at one end of the inclined surface away from the top-pushing assembly. Thus, when it is necessary to limit the member to be welded, it is only necessary to place the member to be welded along the inclined surface of the first limiting member 310, and the second limiting member 320 can support and limit the member to be welded from its bottom.
