[0018] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] The following describes a floating plate vent valve housing processing device according to an embodiment of the present application with reference to the accompanying drawings.

[0020] like Figure 1-Figure 7 As shown, the floating vent valve housing processing equipment of the embodiment of the present application may include: a processing table 1, a supporting mechanism 2, a pressing mechanism 3 and a welding assembly 4.

[0021] A plurality of first guide grooves 20 are provided on the processing table 1 , and the plurality of first guide grooves 20 are arranged in a radial ring array.

[0022] In the above embodiment, support feet are provided at the four corners of the bottom of the processing table 1. The support feet can reduce the contact area between the processing table 1 and the ground, thereby increasing the pressure between the two and increasing the stability of the device during use.

[0023] The support mechanism 2 includes a central rod 21 , a first position-limiting assembly 22 , a second position-limiting assembly 23 and a plurality of support rods 24 .

[0024] The center rod 21 is vertically arranged on the processing table 1 , and the center rod 21 is used to support the first limiting assembly 22 and the second limiting assembly 23 .

[0025] The first and second limiting assemblies 22, 23 are respectively connected to the center rod 21, wherein the first limiting assembly 22 is slidably connected to the plurality of first guide slots 20. The first and second limiting assemblies 22, 23 are used to adjust the tilt angle of the support rod 24 to accommodate various specifications of the frustum structure.

[0026] Multiple support rods 24 are arranged in a circular array, and the support rods 24 are respectively connected to the first limit assembly 22 and the second limit assembly 23, wherein one end of the multiple support rods 24 is located in the corresponding first guide groove 20, and the metal plate of the ventilation valve shell to be processed is fitted with the multiple support rods 24.

[0027] Two arc-shaped guide grooves 30 are symmetrically arranged with the support mechanism 2 as the center, and the pressing mechanism 3 includes a driving component 32 and two pressing components 31.

[0028] Among them, the driving component 32 is arranged at the bottom of the processing table 1, and the two pressing components 31 are symmetrically arranged above the processing table 1. The driving component 32 passes through the two arc-shaped guide grooves 30 and is connected to the bottom of the corresponding pressing component 31. The pressing component 31 is used to assist in docking the two ends of the metal sheet. The pressing component 31 is in contact with the outer wall of the metal sheet of the ventilation valve to be processed.

[0029] The welding assembly 4 is arranged on the processing table 1, and the welding assembly 4 is used to perform welding processing on the butt joints of the two ends of the metal plate.

[0030] In the above embodiment, the number of the plurality of first guide grooves 20 and the number of the plurality of support rods 24 are equal, and can be 4, 5, 6, etc., which is not specifically limited here.

[0031] It should be noted that the processing table 1 described in this embodiment is also provided with a controller, and the pressing mechanism 3 and the welding assembly 4 are respectively connected to the controller. Relevant technicians can operate the equipment through the operation switch on the controller.

[0032] It should be noted that, in the initial state, the two pressing assemblies 31 are respectively located at one end of the two arc-shaped guide grooves 30 away from the welding assembly 4 .

[0033] In the embodiment of the present application, the number of the plurality of first guide grooves 20 and the number of the plurality of support rods 24 may be five.

[0034] Specifically, the relevant operator takes the sheared metal sheet raw material, which has the shape of an unfolded structure diagram of a truncated cone, with two arc-shaped sides of unequal lengths and two straight sides of equal length.

[0035] The relevant operator bends the metal sheet and inserts it between the two pressing components 31 and the support mechanism 2. At this time, the pressing component 31 and the support mechanism 2 both come into contact with the metal sheet. Afterwards, the center of the longer arc-shaped side of the metal sheet is aligned with a first guide groove 20, so that the metal sheet comes into contact with the processing table 1. The controller sends an operation signal to the drive component 32, which drives the two pressing components 31 to move in the corresponding arc-shaped guide grooves 30. Under the action of the pressing components 31, the metal sheet continues to bend and deform. The two pressing components 31 move to the ends of the arc-shaped guide grooves 30 respectively (this working condition can be obtained through the position sensor). The two ends of the metal sheet are butted and bent into a frustum structure.

[0036] Next, the welding assembly 4 performs welding processing on the joints at both ends of the metal plate. After the processing is completed, the pressing mechanism 3 is reset, and the relevant operator can remove the vent valve shell with a frustum structure and place it in the temporary storage position of the finished product, repeat the above steps, and continue to process the vent valve shell.

[0037] In the above embodiment, the pressing mechanism 3 is used to roll on the outer wall of the metal plate to assist in docking its two ends, so that the operator's hands are away from the welding part, improving the safety of the production process. At the same time, the supporting mechanism 2 acts inside the frustum structure to avoid deformation of the workpiece due to external force during welding, thereby ensuring processing accuracy and finished product quality.

[0038] As a possible situation, in order to ensure the accuracy of welding, when the center of the longer arc-shaped edge of the metal plate is aligned with a first guide groove 20, the relevant operator can first mark the center of the arc-shaped edge, and during the alignment process, the laser irradiation can be used to coincide with the mark (the laser lamp is installed at the first guide groove 20 facing the welding component 4), thereby ensuring that the center of the arc-shaped edge is aligned with the first guide groove 20.

[0039] In one embodiment of the present application, Figure 3 As shown, the first limiting assembly 22 includes a spring 221 , a first connecting plate 222 , a plurality of first connecting rods 223 , a first knob 225 and a plurality of limiting sliders 224 .

[0040] Among them, the spring 221 and the first connecting plate 222 are respectively arranged on the outside of the center rod 21, and the first connecting plate 222 is located above the spring 221, one end of the multiple first connecting rods 223 is pivotally connected to the first connecting plate 222, and the other end of the multiple first connecting rods 223 is pivotally connected to the multiple limit sliders 224, and the multiple limit sliders 224 are slidably arranged inside the corresponding first guide groove 20, one end of the support rod 24 is pivotally connected to the limit slider 224, the first knob 225 is threadedly connected to the center rod 21, and the first knob 225 abuts against the first connecting plate 222.

[0041] In one embodiment of the present application, Figure 3 As shown, the second limiting assembly 23 includes a top plate 231 , a plurality of hinged links 232 , a second connecting plate 233 and a second knob 234 .

[0042] Among them, the top plate 231 is set at the end of the center rod 21, one end of multiple hinged links 232 is pivotally connected to the top plate 231, the second connecting plate 233 is sleeved on the outside of the center rod 21, the other end of multiple hinged links 232 is pivotally connected to the second connecting plate 233, the hinged link 232 is slidingly connected to the support rod 24, the second knob 234 is threadedly connected to the center rod 21, and the second knob 234 abuts against the second connecting plate 233.

[0043] In one embodiment of the present application, Figure 3 and Figure 4 As shown, two connecting members 251 are symmetrically provided on the hinged link 232 , and a guide rail 253 is integrally formed near the other end of the support rod 24 , a first slider 252 is slidably connected to the guide rail 253 , and the two connecting members 251 are pivotally connected to the first slider 252 .

[0044] In the above embodiment, when the specifications of the conical structure of the vent valve housing change, after the two ends of the metal plate are connected, the inner wall of the conical structure cannot fit with the support mechanism 2, and the relevant operator needs to adjust the angle of the support rod 24 through the first limit component 22 and the second limit component 23.

[0045] Specifically, the relevant operator rotates the first knob 225, and the first knob 225 is threadedly connected to the center rod 21. The first knob 225 can push the first connecting plate 222 to move, the spring 221 is compressed, the angle of the first connecting rod 223 changes, and the position of the limiting slider 224 in the first guide groove 20 changes, thereby driving the angle of one end of the support rod 24 to change.

[0046] The relevant operator rotates the second knob 234, which is threadedly connected to the center rod 21. The second knob 234 can push the second connecting plate 233 to move, causing the hinged link 232 to deform, thereby driving the angle of the other end of the support rod 24 to change.

[0047] When the angle of the support rod 24 changes, the connecting member 251 can drive the first slider 252 to move on the guide rail 253. The angles of multiple support rods 24 can be adjusted simultaneously, thereby expanding the scope of application of the processing equipment.

[0048] In one embodiment of the present application, Figure 6As shown, the driving assembly 32 includes an electric telescopic rod 321 , two first push plates 322 , two first connecting shafts 323 , two second push plates 324 , a guide rod 326 and two second connecting shafts 325 .

[0049] Among them, the electric telescopic rod 321 is arranged at the bottom of the processing table 1, the output end of the electric telescopic rod 321 is connected to the guide rod 326, one end of the two first push plates 322 is pivotally connected to the guide rod 326, and the other end of the two first push plates 322 is pivotally connected to the two second push plates 324 through two first connecting shafts 323 respectively. The center rod 21 passes through the processing table 1, one end of the two second push plates 324 is pivotally connected to the center rod 21 respectively, and the other end of the two second push plates 324 is pivotally connected to the corresponding second connecting shafts 325 respectively. The second connecting shaft 325 passes through the arc guide groove 30, and the two second connecting shafts 325 are connected to the corresponding pressing components 31.

[0050] In one embodiment of the present application, Figure 6 As shown, a third guide groove 327 is provided at the bottom of the processing table 1 , one end of the guide rod 326 extends into the interior of the third guide groove 327 , and the guide rod 326 is slidably connected to the third guide groove 327 .

[0051] It can be understood that the third guide groove 327 can limit the guide rod 326 during its movement, thereby ensuring the stability of the movement of the guide rod 326.

[0052] In one embodiment of the present application, Figure 5 As shown, the pressing assembly 31 includes a plate 311 , two hand-screwed screws 312 , two U-shaped pieces 313 , a pressing shaft 314 and two rods 315 .

[0053] Among them, the plate body 311 is connected to the second connecting shaft 325, the two hand-screw rods 312 are respectively threadedly connected to the plate body 311, the two C-shaped parts 313 are respectively connected to one end of the corresponding hand-screw rods 312, the two ends of the pressing shaft 314 are rotatably connected to the two rod bodies 315, and the rod body 315 is pivotally connected to the C-shaped part 313.

[0054] Specifically, after the operator sends an operating signal to the pressing mechanism 3 through the controller, first, the driving assembly 32 operates, the electric telescopic rod 321 pushes the guide rod 326 to move, the guide rod 326 pushes the two first push plates 322 to move, and the angles of the two first push plates 322 change, thereby applying a force to the two second push plates 324. Under the limiting action of the center rod 21, the two second push plates 324 move relative to each other with the center rod 21 as the center, thereby driving the pressing assembly 31 to move, and the pressing shaft 314 rolls on the surface of the metal sheet, so that the metal sheet fits the outside of the support mechanism 2.

[0055] When the specifications of the frustum structure change, the relevant operator can adjust the angle of the pressing shaft 314 by means of two manually-rotated screws 312 so that the pressing shaft 314 fits the surface of the metal sheet.

[0056] As a possible situation, in order to ensure the stability of the pressing assembly 31 during movement, a slider can be set at the bottom of the plate 311 and a track can be set on the processing table 1. The slider can move on the track, thereby limiting the position of the pressing assembly 31 when it moves.

[0057] It should be noted that the metal sheet itself has a certain deformation ability, and the relevant operators can easily place it between the two pressing shafts 314 and the support rod 24, and the pressing shaft 314 and the support rod 24 only play a limiting role. The force between the pressing shaft 314 and the support rod 24 and the metal sheet is small, and the pressing shaft 314 will not cause excessive deformation of the metal sheet during the rolling process.

[0058] As a possible situation, in order to facilitate the adjustment of the pressing component 31 and the supporting mechanism 2, before mass processing, adjustments can be made with the help of a finished frustum structure. The specific operations are shown in the above steps. The relevant operators can observe the fit between the pressing component 31 and the supporting mechanism 2 and the inner wall of the frustum structure. The adjustment process is convenient and quick.

[0059] In one embodiment of the present application, Figure 1 and Figure 7 As shown, the welding assembly 4 includes a vertical plate 41 , two hydraulic telescopic rods 42 , a movable slide 43 and a welding gun component 44 .

[0060] The vertical plate 41 is arranged on the processing table 1 , two hydraulic telescopic rods 42 are respectively installed on the vertical plate 41 , the output ends of the hydraulic telescopic rods 42 are pivotally connected to the movable slide 43 , and the welding gun component 44 is arranged on the movable slide 43 .

[0061] It should be noted that the specific structures of the movable slide 43 and the welding gun component 44 described in this embodiment have been disclosed in the prior art and will not be described in detail here.

[0062] Specifically, during the operation of the welding assembly 4, the movable slide 43 can drive the welding nozzle of the welding gun component 44 to move along the butt joints at both ends of the metal plate, thereby performing welding processing on the butt joints of the metal plate.

[0063] When the specifications of the frustum structure formed by the metal sheet change, the relevant operator can send an operation signal to the two hydraulic telescopic rods 42 through the controller. The hydraulic telescopic rods 42 push the movable slide 43 to change its angle, so that during the welding process, the welding nozzle part of the welding gun component 44 always maintains a fixed distance from the welding position.

[0064] After the processing of the vent valve housing is completed, the hydraulic telescopic rod 42 can drive the movable slide 43 and the welding gun component 44 to reset, thereby making it convenient for relevant operators to remove the finished product.

[0065] In summary, the floating vent valve shell processing equipment of the embodiment of the present application uses a pressing mechanism to roll on the outer wall of the metal plate to assist in docking its two ends, so that the operator's hands are away from the welding part, thereby improving the safety of the production process. At the same time, the support mechanism acts inside the frustum structure to avoid deformation of the workpiece due to external force during welding, thereby ensuring processing accuracy and finished product quality.
