Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stud welding, and more specifically, to a stud pusher mechanism and stud welding equipment. Background Technology
[0002] The stud welding equipment has a stud outlet conduit, a stud inlet conduit, and an outer clamp. The stud outlet conduit and the stud inlet conduit are connected. The outer clamp is connected to the stud outlet conduit. The stud feeding mechanism blows the stud in through the stud inlet conduit. The stud pushing mechanism pushes the stud into the outer clamp along the stud outlet conduit. The stud flange is located outside the outer clamp and maintains a preset distance from the end face of the outer clamp.
[0003] In the prior art, the pusher mechanism uses an inner clamp to push the screw. During the pushing process, the end of the inner clamp abuts against the flange of the screw. After the flange of the screw extends out of the outer clamp, due to the limited pushing force of the pusher mechanism, the flange of the screw easily abuts against the end face of the outer clamp, making it difficult to maintain a preset distance between the flange of the screw and the end face of the outer clamp. Therefore, it is difficult to push the screw to the preset welding position.
[0004] There is currently no effective solution to the problem that existing push-pin mechanisms have difficulty pushing screws to the preset position. Utility Model Content
[0005] The main purpose of this utility model is to provide a push-pin mechanism and stud welding equipment to solve the problem that the push-pin mechanism in the prior art is difficult to push the screw to the preset welding position.
[0006] To achieve the above objectives, according to one aspect of the present invention, a push-nail mechanism is provided, comprising: a movable rod for sliding connection with a screw outlet conduit; an inner clamp connected to the end of the movable rod, the inner clamp having a receiving cavity for accommodating a target screw; and a pusher disposed within the receiving cavity of the inner clamp and connected to the end of the movable rod. During the push-nail operation, the movable rod moves a first preset distance to allow the target screw to enter the receiving cavity of the inner clamp, and the pusher abuts against the stud end face of the target screw. The movable rod then continues to move a second preset distance to allow the pusher to push the target screw to a preset welding position.
[0007] Furthermore, the pusher is detachably connected to the moving rod.
[0008] Furthermore, the pusher is threadedly connected to the moving rod, and the effective length of the pusher is changed by adjusting the movement of the pusher relative to the moving rod.
[0009] Furthermore, the pusher is threadedly connected to the moving rod via a connector, and the pusher is threadedly connected to the connector.
[0010] Furthermore, the end of the moving rod is provided with a first connecting pipe, the inner wall of the first connecting pipe is provided with internal threads, the connecting part includes a first connecting section and a second connecting section, the diameter of the first connecting section is smaller than the diameter of the second connecting section, the first connecting section is threadedly connected to the first connecting pipe, the second connecting section is provided with a threaded hole, and the pusher is threadedly connected to the second connecting section.
[0011] Furthermore, the inner clamp is detachably connected to the moving rod.
[0012] Furthermore, the inner clamp is provided with a second connecting tube and multiple connecting pieces. The inner clamp is connected to the moving rod through the second connecting tube, and the multiple connecting pieces are arranged at intervals along the circumference of the second connecting tube, forming a receiving cavity.
[0013] Furthermore, the end of the moving rod is provided with a first connecting tube, the outer wall of the first connecting tube is provided with external threads, the inner wall of the second connecting tube is provided with internal threads, and the second connecting tube is threadedly connected to the first connecting tube.
[0014] Furthermore, the inner wall of the end of the connecting piece away from the second connecting tube is provided with an inclined surface.
[0015] According to another aspect of the present invention, a stud welding device is provided, which includes a pusher mechanism, wherein the pusher mechanism is the pusher mechanism described above.
[0016] Applying the technical solution of this utility model, during the push-nail operation, the moving rod first moves a first preset distance, allowing the target screw to enter the receiving cavity of the inner clamp and abut against the pushing member. The inner clamp acts as a guide, ensuring precise alignment of the stud end face of the target screw with the pushing member. The moving rod continues to move a second preset distance, allowing the force on the moving rod to act on the stud end face of the target screw through the pushing member. This separates the flange of the target screw from the end face of the inner clamp, creating a preset distance between the flange of the target screw and the end face of the outer clamp, thus pushing the screw to the preset welding position. The push-nail mechanism in the above solution utilizes the pushing member to apply a pushing force to the stud end face of the target screw, ensuring that the target screw can be accurately moved to the preset welding position.

[0035] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a push-nail mechanism is provided.
[0036] Specifically, the screw-pushing mechanism includes a movable rod 10, an inner clamp 20, and a pusher 30. The movable rod 10 is slidably connected to the screw outlet conduit. The inner clamp 20 is connected to the end of the movable rod 10 and has a receiving cavity for accommodating the target screw. The pusher 30 is disposed within the receiving cavity of the inner clamp 20 and is connected to the end of the movable rod 10. During the screw-pushing operation, the movable rod 10 moves a first preset distance so that the target screw enters the receiving cavity of the inner clamp 20, and the pusher 30 abuts against the stud end face of the target screw. The movable rod 10 continues to move a second preset distance so that the pusher 30 pushes the target screw to a preset welding position.
[0037] In the embodiments of this application, during the nail-pushing operation, the moving rod 10 first moves a first preset distance, causing the target screw to enter the receiving cavity of the inner collet 20 and abut against the pushing member 30. The inner collet 20 acts as a guide to ensure precise alignment of the stud end face of the target screw with the pushing member 30. The moving rod 10 then moves a second preset distance, causing the force on the moving rod 10 to act on the stud end face of the target screw through the pushing member 30. This allows the flange of the target screw to separate from the end face of the inner collet 20, thereby creating a preset distance between the flange of the target screw and the end face of the outer collet, thus pushing the screw to a preset welding position. The nail-pushing mechanism in the above scheme utilizes the pushing member 30 to apply a pushing force to the stud end face of the target screw, ensuring that the target screw can be accurately moved to the preset welding position.
[0038] In one exemplary embodiment of this application, the pusher 30 is detachably connected to the moving rod 10.
[0039] In the embodiments of this application, the pusher 30 is detachably connected to the moving rod 10. Different lengths of pushers 30 can be replaced to adapt to the welding requirements of different target screws, so that the target screw can be accurately moved to the welding position. At the same time, if the pusher 30 is bent or damaged, only the pusher 30 can be replaced to reduce maintenance costs.
[0040] For example, the pusher 30 and the moving rod 10 can be detachably connected by screws. Alternatively, the pusher 30 and the moving rod 10 can be detachably connected by threads. Alternatively, the pusher 30 and the moving rod 10 can be detachably connected by snap-fit.
[0041] Furthermore, the pusher 30 is threadedly connected to the moving rod 10, and the effective length of the pusher 30 is changed by adjusting the movement of the pusher 30 relative to the moving rod 10.
[0042] In the embodiments of this application, by adjusting the threaded length between the pusher 30 and the moving rod 10, the effective length of the pusher 30 can be changed, thereby adapting to the welding requirements of different target screws, so that the target screw can be accurately moved to the welding position.
[0043] In one exemplary embodiment of this application, the pusher 30 is threadedly connected to the moving rod 10 via the connector 40, and the pusher 30 is threadedly connected to the connector 40.
[0044] In the embodiments of this application, the radial dimension of the pusher 30 is much smaller than the radial dimension of the threaded end of the moving rod 10. The connector 40 is provided to accommodate the dimensions of the moving rod 10 and the pusher 30, so that there is no need to improve the threaded end of the moving rod 10 and the threaded end of the pusher 30, thereby reducing equipment costs.
[0045] like Figure 1, Figure 2 , Figure 3 As shown, the end of the moving rod 10 is provided with a first connecting pipe 11, the inner wall of the first connecting pipe 11 is provided with internal threads, the connecting member 40 includes a first connecting section 41 and a second connecting section 42, the diameter of the first connecting section 41 is smaller than the diameter of the second connecting section 42, the first connecting section 41 is threadedly connected to the first connecting pipe 11, the second connecting section 42 is provided with a threaded hole, and the pusher 30 is threadedly connected to the second connecting section 42.
[0046] In the embodiments of this application, the connector 40 is threadedly connected to the moving rod 10 via a first connecting section 41. The diameter of the first connecting section 41 is smaller than the diameter of the second connecting section 42. The second connecting section 42 serves as a limiting element, restricting the movement of the connector 40 relative to the moving rod 10 by abutting against the end face of the first connecting tube 11, thereby achieving precise positioning of the connector 40. The second connecting section 42 is provided with an internal thread for threaded connection with the pusher 30. The effective length of the pusher 30 can be adjusted by rotating it to adapt to the welding requirements of different target screws, so that the target screw can be accurately moved to the welding position.
[0047] Among them, the pusher 30 can be a pin with external threads.
[0048] In one exemplary embodiment of this application, the inner clamp 20 is detachably connected to the moving rod 10.
[0049] In the embodiments of this application, the inner collet 20 is detachably connected to the moving rod 10. When the inner collet 20 needs to be replaced due to wear or damage, only the inner collet 20 portion needs to be replaced, thereby reducing maintenance costs. When the specifications of the target screw change, the requirement can be met simply by replacing the corresponding type of inner collet 20, thereby reducing equipment costs. Simultaneously, the detachable connection between the inner collet 20 and the moving rod 10 facilitates the installation and replacement of the pusher 30.
[0050] like Figure 4 As shown, the inner clamp 20 is provided with a second connecting pipe 21 and a plurality of connecting pieces 22. The inner clamp 20 is connected to the moving rod 10 through the second connecting pipe 21. The plurality of connecting pieces 22 are arranged at intervals along the circumference of the second connecting pipe 21, and the plurality of connecting pieces 22 surround to form a receiving cavity.
[0051] In the embodiments of this application, the connecting piece 22 and the second connecting tube 21 are generally coplanar, that is, the connection angle between the connecting piece 22 and the second connecting tube 21 is 0. The radial dimension of the receiving cavity can be changed by adjusting the connection angle of the connecting piece 22 relative to the second connecting tube 21 so that the target screw can smoothly enter the receiving cavity of the inner collet 20, and avoid the stud part of the target screw from getting caught with the inner collet 20, so as to affect the pushing process of the target screw.
[0052] Furthermore, such as Figure 4 As shown, the end of the moving rod 10 is provided with a first connecting pipe 11, the outer wall of the first connecting pipe 11 is provided with external threads, the inner wall of the second connecting pipe 21 is provided with internal threads, and the second connecting pipe 21 is threadedly connected to the first connecting pipe 11.
[0053] In the embodiments of this application, the inner collet 20 is threadedly connected to the moving rod 10 via the second connecting pipe 21, making it easier to replace the inner collet 20. Simultaneously, the limited length of the inner collet 20 can be adjusted by adjusting the threaded length to accommodate different specifications of wooden screws.
[0054] Furthermore, such as Figure 5 An inclined surface 221 is provided on the inner wall of the end of the connecting piece 22 away from the second connecting pipe 21.
[0055] In embodiments of this application, the inclined surface 221 serves as a guide surface to facilitate the insertion of the target screw into the receiving cavity of the inner collet 20.
[0056] According to another specific embodiment of this application, a stud welding device is provided, which includes a pusher mechanism, the pusher mechanism being the pusher mechanism in the above embodiment.
[0057] In the embodiments of this application, during the push-nail operation, the moving rod 10 first moves a first preset distance, causing the target screw to enter the receiving cavity of the inner clamp 20 and abut against the pusher 30. The inner clamp 20 acts as a guide to ensure precise alignment of the stud end face of the target screw with the pusher 30. The moving rod 10 then moves a second preset distance, causing the force on the moving rod 10 to act on the stud end face of the target screw through the pusher 30. This allows the flange of the target screw to separate from the end face of the inner clamp 20, thereby creating a preset distance between the flange of the target screw and the end face of the outer clamp, pushing the screw to the preset welding position. The push-nail mechanism in the above scheme uses the pusher 30 to apply a pushing force to the stud end face of the target screw, ensuring that the target screw can smoothly reach the preset welding position, thereby improving the welding accuracy of the stud welding equipment.
[0058] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0059] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.
[0060] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
