[0041] As described in the background art, the surfacing welding of the inner wall of the spherical head 10 needs to be carried out on a welding positioner. The clamping device of the spherical head 10 of the present application is mainly used to position and fix the spherical head 10 on the working panel 20 of the welding positioner, so as to facilitate the surfacing welding operation of the inner wall of the spherical head 10.

[0042] The clamping device of the spherical head 10 of the present utility model will be described in detail below with reference to the drawings.

[0043] Please refer to Figure 1 As shown, the clamping device of the spherical head 10 of the embodiment of the present utility model is used to position and fix the spherical head 10 on the working panel 20. Among them, the working panel 20 can specifically be the working panel 20 of a welding positioner.

[0044] As Figure 1 shown, the clamping device of the spherical head 10 includes a base 100, a plurality of pressing components 200, and a plurality of jacking components 300. The bottom surface of the base 100 is attached to the working panel 20, and the base 100 is used to support and fix the spherical head 10.

[0045] A plurality of pressing components 200 are arranged at intervals around the base 100 on the working panel 20, and each pressing component 200 can respectively press towards the base 100 in a direction perpendicular to the working panel 20, so that the plurality of pressing components 200 can press the base 100 on the working panel 20.

[0046] A plurality of pressing members 300 are arranged around the base 100 at intervals on the working panel 20. Each pressing member 300 can respectively abut against the base 100 in a direction parallel to the working panel 20, so that the plurality of pressing members 300 can clamp and fix the base 100 on the working panel 20.

[0047] The spherical head 10 clamping device according to the embodiment of the present application supports and fixes the spherical head 10 through the base 100, presses the base 100 against the working panel 20 through the pressing member 200, and clamps and fixes the base 100 on the working panel 20 through the pressing member 300, so that the spherical head 10 can be reliably positioned and fixed on the working panel 20. The spherical head 10 clamping device has a simple structure and is convenient to operate. There is no need to weld a plurality of rib plates between the spherical head 10 and the working panel 20 for support and fixation as in the traditional technology, which greatly saves the operation time and is beneficial to improving the product manufacturing efficiency.

[0048] As Figure 1 shown, in one embodiment, the base 100 includes a bottom plate 110 and a support cylinder 120. The bottom plate 110 is placed in contact with the working panel 20. Among them, the bottom plate 110 can be a circular plate or a rectangular plate. Specifically, the shape of the bottom plate 110 can be designed to adapt to the shape of the working panel 20 of the welding positioner.

[0049] Among them, the support cylinder 120 can be a cylindrical structure. Or the support cylinder 120 can also be an annular cylindrical structure with a rectangular cross-section.

[0050] As Figure 1 shown, the bottom surface of the bottom plate 110 is used to be in contact with the working panel 20. The top surface of the bottom plate 110 is connected to the bottom end of the support cylinder 120. Among them, the bottom plate 110 and the support cylinder 120 can be fixedly connected by welding.

[0051] The top end of the support cylinder 120 is used to support and fix the spherical head 10. In this embodiment, the inside of the support cylinder 120 is hollow, and its top end forms an annular opening that can accommodate and place the spherical head 10. Among them, the top end of the support cylinder 120 and the spherical head 10 can be fixedly connected by spot welding. That is, several weld points are formed between the top end of the support cylinder 120 and the outer peripheral wall of the spherical head 10 to achieve the fixation of the two. Thus, it can not only ensure the effective fixation between the support cylinder 120 and the spherical head 10 to realize the clamping of the spherical head 10, but also realize rapid disassembly and welding before clamping the next spherical head 10.

[0052] See Figure 3, in one embodiment, an inclined surface 121 is provided at the top end of the support cylinder 120. The inclined surface 121 causes the top end of the support cylinder 120 to form an annular groove with an opening that gradually expands from the bottom end of the support cylinder 120 to the top end of the support cylinder 120. By providing the inclined surface 121 at the top end of the support cylinder 120 and forming an annular groove with a gradually expanding opening, the support cylinder 120 can better accommodate spherical heads 10 of different sizes. For example, as Figure 1 shown, the support cylinder 120 can support and fix a spherical head 10 with a smaller diameter. Also, as Figure 2 shown, the support cylinder 120 can also support and fix a spherical head 10 with a larger diameter.

[0053] By providing the inclined surface 121 at the top end of the support cylinder 120, it is also beneficial to increase the contact area between the support cylinder 120 and the outer peripheral surface of the spherical head 10, so as to more stably support spherical heads 10 of various different sizes.

[0054] Refer to Figure 3 , in one embodiment, the base 100 further includes a plurality of reinforcing rib plates 130. The plurality of reinforcing rib plates 130 are arranged at intervals along the circumferential direction of the support cylinder 120 between the bottom plate 110 and the support cylinder 120. Each reinforcing rib plate 130 is respectively connected to the outer peripheral surfaces of the bottom plate 110 and the support cylinder 120. By providing the reinforcing rib plates 130, the connection strength between the bottom plate 110 and the support cylinder 120 can be enhanced, and the structural strength and load-bearing capacity of the base 100 can be improved.

[0055] In the embodiments of the present application, the plurality of pressing components 200 can be arranged in a circumferential array along the support cylinder 120 on the working panel 20. As Figure 1 shown, each pressing component 200 presses on the top surface of the bottom plate 110.

[0056] Refer to Figure 1 and Figure 4 , in one embodiment, the pressing component 200 includes a pressing plate 210 and a pressing member 220. The pressing plate 210 is movably arranged on the working panel 20, and the pressing plate 210 can move towards the base 100 and abut against the circumferential edge of the base 100. The pressing member 220 is connected between the pressing plate 210 and the working panel 20, and the pressing member 220 can drive the pressing plate 210 to press towards the base 100.

[0057] For example, the pressing plate 210 is rotatably connected to the working panel 20. As Figure 4 shown, the pressing plate 210 has opposite ends, and a connection hole 211 penetrating through the pressing plate 210 is provided at one end of the pressing plate 210. The connection hole 211 is used for passing through a connecting member 230, and the pressing plate 210 is rotatably connected to the working panel 20 through the connecting member 230.

[0058] Among them, the connection hole 211 can be a threaded hole. The connecting member 230 can be a screw. Correspondingly, fixing holes for fastening the connecting screw can be provided on the working panel 20.

[0059] The other end of the pressing plate 210 is used to abut against the circumferential edge of the base 100. Among them, the other end of the pressing plate 210 can abut against the top edge of the base 100. A through hole 212 for passing through the pressing member 220 is provided in the middle of the pressing plate 210. The pressing member 220 can be arranged to extend in a direction perpendicular to the working panel 20. Specifically, the pressing member 220 can be a bolt. During the process of tightening the bolt, the bolt can cause the pressing plate 210 to press against the bottom plate 110 in a direction perpendicular to the working panel 20, so as to press the base 100 against the working panel 20.

[0060] In other embodiments, the pressing member 220 can also be omitted. When the pressing plate 210 abuts against the top surface of the bottom plate 110, by tightening the screw (i.e., the connecting member 230) downward in a direction perpendicular to the working panel 20, the pressing plate 210 is pressed downward against the bottom plate 110, achieving the purpose of pressing the base 100 against the working panel 20.

[0061] As Figure 1 shown, since the pressing plate 210 is rotatably connected to the working panel 20, when it is necessary to press the base 100 against the working panel 20, the pressing plate 210 can be rotated toward the base 100 so that its end abuts against the top surface of the bottom plate 110, and then the pressing member 220 is used to connect and fix the pressing plate 210 to the working panel 20, thereby pressing the base 100 against the working panel 20. When it is not necessary to press the base 100 against the working panel 20, the connection between the pressing member 220 and the pressing plate 210 and the working panel 20 is released, and the pressing plate 210 is rotated so that its end is away from the top surface of the bottom plate 110.

[0062] In other embodiments, the pressing plate 210 can also be connected to the working panel 20 so as to be movable up and down in a direction perpendicular to the working panel 20. When it is necessary to press the base 100 against the working panel 20, the pressing plate 210 is moved downward to press against the base 100. When it is not necessary to press the base 100 against the working panel 20, the pressing plate 210 is moved upward to release the base 100.

[0063] In the embodiments of the present application, multiple top pressing members 300 can be arranged in a circumferential array on the working panel 20 along the support cylinder 120. As Figure 1 shown, each top pressing member 300 acts in a pressing manner on the outer peripheral surface of the support cylinder 120.

[0064] See Figure 1 and Figure 5, in one embodiment, the pressing member 300 includes a fixed seat 310 and a pressing member 320. The fixed seat 310 is detachably connected to the working panel 20. Exemplarily, through holes for passing fasteners are formed in the fixed seat 310. Correspondingly, fixing holes for connecting fasteners may be provided on the working panel 20. By passing the fasteners through the through holes and firmly connecting them to the fixing holes, a detachable fixed connection between the fixed seat 310 and the working panel 20 can be achieved.

[0065] As Figure 5 shown, the pressing member 320 is movably connected to the fixed seat 310 and can move toward the base 100 in a direction parallel to the working panel 20. Exemplarily, the pressing member 320 is a screw rod, and a nut 311 is provided on the fixed seat 310. The screw rod is threadedly connected to the nut 311, and the screw rod extends in a direction parallel to the working panel 20. In this embodiment, by screwing the screw rod and the nut 311, when the screw rod rotates relative to the nut 311, the end of the screw rod can approach or move away from the support cylinder 120, thereby achieving the purpose of pressing the support cylinder 120. Among them, the rotation of the screw rod needs to be realized by an external force. When no external force is applied, the relative position between the screw rod and the nut 311 is fixed.

[0066] In other embodiments, the pressing member 320 may also be a sliding rod, and a sliding groove is provided on the fixed seat 310. The sliding rod is slidably disposed in the sliding groove. When the end of the sliding rod presses against the outer peripheral wall of the support cylinder 120, the relative position between the sliding rod and the sliding groove can be fixed by using fixing members such as pins.

[0067] When the clamping device of the spherical head 10 in the embodiment of the present application is in use:

[0068] Place the spherical head 10 to be subjected to curved surface surfacing on the top end of the support cylinder 120 and perform spot welding to fix the two. Place the bottom plate 110 of the base 100 on the working panel 20 at the reserved position on the working panel 20.

[0069] Rotate the pressing plate 210 so that its end abuts against the top surface of the bottom plate 110, and tighten the pressing member 220 to press the pressing plate 210 against the bottom plate 110. Operate each pressing plate 210 and each pressing member 220 in sequence, so that the plurality of pressing members 200 press the base 100 against the working panel 20.

[0070] Rotate the screw rod so that its end abuts against the outer peripheral surface of the support cylinder 120, and operate each screw rod in sequence so that the plurality of pressing members 300 clamp and fix the base 100 on the working panel 20.

[0071] Through the above operations, the spherical head 10 can be positioned and fixed on the working panel 20, and then the inner surface of the spherical head 10 can be automatically surfaced by a welding positioner.

[0072] The clamping device for the spherical head 10 according to the embodiment of the present application has a simple structure and convenient operation, and can clamp and fix spherical heads 10 with different specifications and special structures. Thus, the operation time is greatly saved, which is beneficial to improving the product manufacturing efficiency.

[0073] Since the spherical head 10 is positioned and fixed by a plurality of pressing components 200 and a plurality of jacking components 300, before the position of the spherical head 10 is in place, the position of the base 100 can be adjusted according to needs to adjust the position of the spherical head 10, so as to effectively ensure the accuracy of the positioning of the spherical head 10.

[0074] After the spherical head 10 is clamped and fixed by the clamping device for the spherical head 10 of the present application, the internal curved surface of the spherical head 10 is horizontally surfacing welded by a welding positioner, replacing the original manual shielded metal arc welding surfacing, which can greatly save labor costs and shorten the product manufacturing period.

[0075] The above embodiments are only illustrative examples of the structure. The structures in each embodiment are not fixedly combined structures. Without structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0076] Although the present utility model has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
