[0073] This invention provides a method for processing and manufacturing a split-type faucet body, such as... Figures 2-6 As shown, the main body of the faucet includes a housing 110, a valve core seat 130, and a base 150, wherein:

[0074] The valve core seat 130 includes a valve core seat housing 131 and a first limiting piece 132;

[0075] The base 150 includes a base housing 151 and a second limiting piece 152;

[0076] The outer shell 110, valve core seat shell 131, and base shell 151 are made of stainless steel hollow tubes; the hollow tubes include, but are not limited to, round tubes, square tubes, and irregular tubes; the first limiting plate 132 and the second limiting plate 152 are made of stainless steel sheet; the working principle of the faucet, the valve core structure, and the connection between the valve core and the valve core seat shell 131 and the first limiting plate 132 in the split-type faucet provided by the present invention are all existing technologies and will not be described in detail here.

[0077] like Figure 1 As shown, the specific steps of the manufacturing process for a split-type faucet are as follows:

[0078] S10. Select the raw material hollow tube and the raw material sheet. In this step, the stainless steel raw material hollow tube is selected according to the required diameter of the outer shell 110, valve core seat shell 131, and base shell 151, and the stainless steel raw material sheet is selected according to the required thickness of the first limiting plate 132 and the second limiting plate 152.

[0079] S20: Cut the hollow tube of the raw material into segments to form the outer shell 110, valve core seat shell 131, and base shell 151; cut the raw material sheet into pieces to form the first limiting piece 132 and the second limiting piece 152; in this step, the corresponding hollow tube of the raw material in step S10 is cut according to the length of the outer shell 110, valve core seat shell 131, and base shell 151 to form the outer shell 110, valve core seat shell 131, and base shell 151 respectively; the raw material sheet in step S10 is cut according to the diameter and shape of the first limiting piece 132 and the second limiting piece 152 to form the first limiting piece 132 and the second limiting piece 152 respectively.

[0080] S30, clean the first limiting piece 132 and the valve core seat housing 131, weld the first limiting piece 132 to one end of the valve core seat housing 131 to form the valve core seat 130; weld the second limiting piece 152 to one end of the base housing 151 to form the base 150.

[0081] S40. Clean the welded valve core seat 130 and base 150, and position the valve core seat 130 and base 150 in the two ports of the outer shell 110 respectively, and make the other unwelded port of the valve core seat housing 131 and the other unwelded port of the base housing 151 face the adjacent port of the outer shell 110 to form the main body faucet assembly; in order to ensure that the main body faucet assembly has correct assembly during welding, the valve core seat (130) and base (150) are press-fitted to the two ports of the outer shell (110) by manual pressing or by using existing push and press devices.

[0082] S50. Weld the two ends of the main body faucet assembly respectively, so that the other end of the valve core seat housing 131 and the other end of the base housing 151 are welded to the inner wall of the outer shell 110, thus completing the production of the main body faucet.

[0083] The present invention provides a method for manufacturing a split-type faucet body. This method involves cutting stainless steel hollow tubes and stainless steel sheets to create an outer shell 110, a valve core seat shell 131, a base shell 151, a first limiting plate 132, and a second limiting plate 152. The outer shell 110, valve core seat shell 131, base shell 151, first limiting plate 132, and second limiting plate 152 are then welded together to form the valve core seat 130 and base 150. Finally, the valve core seat 130, base 150, and outer shell 110 are welded together to form the faucet body. Compared to traditional methods of machining and milling integral parts from a solid cylinder, the split-type faucet body manufacturing method of the present invention, although increasing welding time, results in a shorter overall welding time. Therefore, it can reduce the overall production time of the faucet body, thereby improving production efficiency and reducing part costs. Simultaneously, it reduces the complexity of the production process.

[0084] In specific implementation, such as Figure 3 As shown, the valve core seat housing 131 has a second water outlet through hole 1311 on its side wall; the first limiting plate 132 has a valve core limiting hole 1322, which is used to limit the valve core; the second limiting plate 152 has a water inlet through hole 1522, which is used for the water supply pipe to pass through.

[0085] Before or during welding in step S30, the first positioning fixture 210 (e.g.) is used. Figure 7 (As shown) Position the relative position of the second water outlet through hole 1311 and the valve core limiting hole 1322; use the second positioning fixture 220 (as shown) Figure 8 (As shown) Positioning water inlet hole 1522.

[0086] like Figure 7As shown, the first positioning fixture 210 includes a first base 211, a cylindrical first guide post 212, and a first boss 213 arranged sequentially. The first boss 213 is set according to the shape and position of the valve core limiting hole 1322 and is adapted to the valve core limiting hole 1322. A first positioning protrusion 2111 is provided on the side wall of the first base 211 on one side of the first guide post 212. A first positioning notch 1312 is provided at one end of the valve core seat housing 131. The second water outlet hole 1311 is positioned in a set position and direction by the engagement of the first positioning notch 1312 and the first positioning protrusion 2111, thereby positioning the relative position of the second water outlet hole 1311 and the valve core limiting hole 1322.

[0087] The length of the first guide post 212 is adapted to the valve core seat housing 131 and is used to position the valve core seat housing 131;

[0088] The first boss 213 is used to position the valve core limiting hole 1322;

[0089] During positioning, the valve core seat housing 131 is fitted onto the first guide post 212, and then the valve core limiting hole 1322 of the first limiting piece 132 is aligned with the first boss 213 and pressed in, so that the first limiting piece 132 is snapped onto the first boss 213; through the combined structure of the first base 211, the first positioning notch 1312, the first positioning protrusion 2111, the first guide post 212, and the first boss 213, the various parts are positioned in the corresponding positions and assembled into the valve core seat 130;

[0090] like Figure 8 As shown, the second positioning fixture 220 includes a second base 221, a cylindrical second guide post 222, and a second boss 223 arranged sequentially; the second boss 223 is arranged according to the shape and position of the water inlet hole 1522 and is adapted to the water inlet hole 1522; preferably, the outline shape of the second boss 223 is semi-circular.

[0091] The length of the second guide post 222 is adapted to the base housing 151 and is used to position the base housing 151.

[0092] The second boss 223 is used to position the water inlet hole 1522.

[0093] During positioning, the base housing 151 is fitted onto the second guide post 222, and then the water inlet hole 1522 of the second limiting piece 152 is aligned with the second boss 223 and pressed in, so that the second limiting piece 152 is engaged with the second boss 223; through the structure of the combination of the second base 221, the second guide post 222 and the second boss 223, the various parts are positioned in the corresponding positions and assembled into the base 150.

[0094] During welding, manual welding can be used; or existing welding equipment (including but not limited to laser welding equipment) can be used. When welding with welding equipment, the first base 211 and the second base 221 can be connected to the rotary cylinder gripper. The welding head of the welding equipment is close to the annular contact area between the valve core seat housing 131 and the first limiting piece 132, or the base housing 151 and the second limiting piece 152. The rotary cylinder gripper drives the first base 211 and the second base 221 to rotate, thereby driving the valve core seat 130 and the base 150, which are positioned and assembled, to rotate. This allows the welding head to weld along the annular contact area between the valve core seat housing 131 and the first limiting piece 132, or the base housing 151 and the second limiting piece 152, thus completing the welding preparation of the valve core seat 130 and the base 150.

[0095] In this embodiment, the relative positions of the valve core seat housing 131 and the first limiting piece 132 are positioned by the first positioning fixture 210, and the relative positions of the base housing 151 and the second limiting piece 152 are positioned by the second positioning fixture 220. This improves the accuracy of assembly and welding of various parts and reduces the increase in defect rate caused by welding angle and positional offsets of various parts. Furthermore, the structural design of the first positioning fixture 210 and the second positioning fixture 220 is simple, allows for rapid assembly of various parts, and has high positioning and assembly efficiency.

[0096] In specific implementation, the outer casing 110 is provided with a first water outlet hole 111 on its side wall;

[0097] In step S40, the housing 110, valve core seat 130 and base 150 are assembled by positioning and assembling the tooling, and the positions of the second water outlet hole 1311 and the first water outlet hole 111 are aligned, as well as the relative positions of the valve core limiting hole 1322 and the water inlet hole 1522 are positioned.

[0098] The positioning assembly includes a first positioning fixture 210, a second positioning fixture 220, a third positioning fixture 230, and a centering fixture 240; the first positioning fixture 210 and the second positioning fixture 220 are the same as those in step S30.

[0100] The first positioning fixture 210, the third positioning fixture 230, and the second positioning fixture 220 are sequentially arranged along the centering direction of the centering fixture 240; at least one of the first positioning fixture 210 and the second positioning fixture 220 is movably connected to the centering fixture 240; the movable connection includes, but is not limited to, the connection structure between the slider and the slide rail, the connection structure between the guide rod and the slider, etc.; the first positioning fixture 210, the second positioning fixture 220, and the third positioning fixture 230 can be moved manually, or the first positioning fixture 210 and the second positioning fixture 220 can be connected to drive motors respectively, and the drive motors push the first positioning fixture 210 and the second positioning fixture 220 toward the third positioning fixture 230;

[0101] During assembly, the valve core seat 130 is placed on the first positioning fixture 210, the base 150 is placed on the second positioning fixture 220, and the outer shell 110 is placed in the limiting groove 231 with the second positioning protrusion 232 engaging in the first water outlet hole 111. The first positioning fixture 210, the second positioning fixture 220, and the third positioning fixture 230 are brought together by the centering guide of the centering fixture 240, with the first positioning fixture 210 positioning the valve core seat 130 and engaging it at one end of the outer shell 110; the second positioning fixture 220 positioning the base 150 and engaging it at the other end of the outer shell 110, thus completing the assembly of the main body faucet assembly.

[0102] The positioning assembly tooling in this embodiment, by employing the first positioning tooling 210 and the second positioning tooling 220 with the same structure as those in step S30, can ensure positioning accuracy and reduce the need for additional redundant structures on the main body of the faucet for positioning. The positioning assembly tooling provided in this embodiment offers fast and high-precision positioning.

[0103] Preferably, the outer shell 110 is interference-fitted with the valve core seat 130 and the base 150 respectively. After assembly, the valve core seat 130 and the base 150 are respectively snapped onto both ends of the outer shell 110, so that the main body faucet assembly remains in the assembled state when it is taken out from the positioning assembly fixture, which facilitates the next step of welding.

[0109] During assembly, such as Figure 9 , Figure 10 As shown, the valve core seat 130 is sleeved on the first guide post 212. The valve core seat 130 is rotated so that the first positioning protrusion 2111 is engaged with the first positioning notch 1312 and the valve core limiting hole 1322 is engaged with the first boss 213.

[0110] Set the base 150 onto the second guide post 222 and adjust the position of the base 150 so that the water inlet hole 1522 is engaged with the second boss 223.

[0111] Place the outer casing 110 into the limiting groove 231, align the first water outlet hole 111 with the second positioning protrusion 232, and engage the first water outlet hole 111 with the second positioning protrusion 232.

[0112] Then, the assembly staff manually or by motor pushes the slider to make the valve core seat 130 enter one end of the housing 110; the base 150 enters the other end of the housing 110, completing the assembly of the main body faucet, so as to facilitate subsequent welding.

[0113] In this embodiment, the structural design combining the first slider 241, the second slider 242, the third slider 243, the guide rail 244, the first base 211, the first guide post 212, the first boss 213, the second base 221, the second guide post 222, the second boss 223, and the limiting groove 231 enables the rapid, accurate, and stable positioning of the relative positions of each part. This lays a good foundation for the subsequent welding of the main body of the faucet, thereby improving the production quality and efficiency of the product.

[0114] In specific implementation, such as Figure 3 As shown, the base 150 is also provided with a fastener 153; the fastener 153 is used to fix the faucet when it is installed; the second limiting piece 152 has a first limiting through hole 1521; one end of the fastener 153 located in the first limiting through hole 1521 is provided with an internal thread. The internal thread structure facilitates connection and fixation with bolts and other connection structures;

[0115] The base housing 151 has an annular groove 1511 at one end of the second limiting piece 152;

[0116] One end of the fastener 153 can be interference-fitted into the first limiting through hole 1521; the second limiting piece 152 can be interference-fitted into the slot 1511.

[0117] Step S20 includes:

[0118] A first limiting through hole 1521 is provided in the second limiting piece 152, and the first limiting through hole 1521 can be interference-fitted with one end of the fastener 153; and an annular groove 1511 is provided on the inner side wall of one end of the base housing 151, and the groove 1511 can be interference-fitted with the second limiting piece 152.

[0119] Step S30 includes:

[0120] After the fastener 153 is inserted into the first limiting through hole 1521 and the second limiting piece 152 is inserted into the slot 1511 by manual means or by using an existing compression device, the fastener 153 and the second limiting piece 152 are welded together, and the second limiting piece 152 is welded to the slot 1511.

[0121] If the second limiting piece 152 is directly welded to the port of the base housing 151 and the fastener 153 is non-interference-fitted with the first limiting through hole 1521 during welding, additional devices or manual fixing of the fastener 153 are required for welding, which affects welding efficiency.

[0122] Using the main body faucet structure and manufacturing method provided by the present invention, the base 150 is already a tightly assembled whole before welding, eliminating the need for additional fixing of the fasteners 153, reducing welding steps and improving welding efficiency.

[0123] In specific implementation, during the welding process in step S50, the main body faucet assembly is fixed by a positioning clamp;

[0124] like Figure 15 , Figure 16 As shown, the positioning fixture includes a fixed housing 410, a horizontal gripper 420, and a rotating base 430; the horizontal gripper 420 is an existing structure and will not be described in detail here.

[0125] The fixed housing 410 is provided with a positioning groove 411 in the vertical direction, which is adapted to the size and dimensions of the outer wall of the housing 110; the positioning groove 411 has an opening; a horizontal gripper 420 is fixedly connected to the upper side wall of the groove opening of the positioning groove 411, and the body and chuck 421 of the horizontal gripper are respectively set on both sides of the groove opening of the positioning groove 411; the main body and the head assembly are fixed in the positioning groove 411 by the horizontal gripper 420; a rotating seat 430 is provided at the bottom of the positioning groove 411.

[0126] During welding, connect the rotating base 430 to the rotary motor or other rotating device, open the horizontal gripper 420, and place the main body faucet assembly inside; then close the horizontal gripper 420 to clamp the main body faucet assembly (e.g., Figure 16 (As shown); The upper end of the main body faucet assembly is provided with a welding head of a welding device. When the rotating seat 430 rotates, the welding head can pass through the contact part between the outer shell 110 and the valve core seat shell 131 in sequence; thus completing the initial welding of the main body faucet assembly.

[0127] Then open the horizontal gripper 420, flip the main body faucet assembly 180° and put it back into the positioning groove 411, close the horizontal gripper 420, and clamp the main body faucet assembly; when the rotating seat 430 rotates, the welding head can pass through the contact part between the outer shell 110 and the base shell 151 in sequence; complete the welding of the main body faucet; then open the horizontal gripper 420 and take out the welded main body faucet.

[0128] In this embodiment, positioning welding is performed using a positioning fixture, which can improve welding accuracy and welding speed.

[0129] In specific implementation, the method steps further include:

[0130] S60. Weld one end of the water outlet pipe 120 to the side wall of the outer casing 110 so that the water outlet pipe 120 is connected to the first water outlet through hole 111. This step uses an automatic laser welding device to weld the water outlet pipe 120.

[0131] S70. Perform welding quality inspection on the welded faucet body; if the quality inspection is qualified, it is a good product and proceeds to the next process; if it fails, it is a defective product; in this step, welding quality is inspected using a testing device; such as Figure 17 , Figure 18 As shown, the detection device includes a first fixing plate 510, a second fixing plate 520 and a third fixing plate 530;

[0132] The second fixing plate 520 and the third fixing plate 530 are respectively disposed on both sides of one end of the first fixing plate 510; the second fixing plate 520, the third fixing plate 530 and the first fixing plate 510 form a detection groove 540;

[0133] The other end of the first fixing plate 510 is provided with a third positioning protrusion 511; the third positioning protrusion 511 extends upward and is adapted to the first positioning notch 1312 in the valve core limiting hole 1322.

[0134] Since the above-mentioned positioning fixtures and positioning devices are used to position and weld the main body faucet, the valve core seat 130 and base 150 inside the main body faucet are precisely welded to the outer shell 110. Therefore, the object of this test is the water outlet pipe 120, and the test is to check whether the water outlet pipe 120 is symmetrically welded to the first water outlet hole 111. If it is not symmetrically welded, it will affect the water output effect of the product, and it will be a defective product.

[0135] During testing, the water outlet pipe 120 is placed in the testing tank 540. If it is welded correctly, the third positioning protrusion 511 can be engaged in the first positioning notch 1312. If the third positioning protrusion 511 cannot be engaged in the first positioning notch 1312, it means that the water outlet pipe 120 is not welded correctly.

[0136] Since the first positioning notch 1312 of the valve core seat housing 131 is partially or completely covered by the welding material when the outer shell 110 is welded to the valve core seat housing 131, the present invention extends the third positioning protrusion 511 upward to the position of the existing first positioning notch 1312 on the valve core limiting hole 1322, and positions it through the first positioning notch 1312. The positioning structure is simple and accurate.

[0137] This invention also provides an automatic laser welding device for the faucet body, wherein one end of the welded water outlet pipe 120 is a bent pipe; the water outlet pipe 120 is welded to the side wall of the faucet body 110; as shown Figure 11As shown, the automatic laser welding equipment for the main body faucet includes a first fixing device 310, a second fixing device 320, a lifting device 330, and a laser device 340. The first fixing device 310 and the second fixing device 320 are, but are not limited to, fixed by mechanical grippers, fixing slots, and other structures. The lifting device 330 includes, but is not limited to, a telescopic cylinder and a telescopic motor. The laser device 340 includes a laser head 341 and a laser generator 342. The laser generator 342, the first fixing device 310, the second fixing device 320, and the lifting device 330 are all connected to a central control computer (not shown in the figure) or a push-button switch 380. The operation of each device is started by controlling the central control computer or by triggering the push-button switch 380.

[0138] The first fixing device 310 is mounted on the base plate 371; the laser head 341 is mounted on one side of the first fixing device 310; the second fixing device 320 is mounted above the first fixing device 310; the lifting device 330 is mounted on the second connecting plate 374; the telescopic end of the lifting device 330 passes through the first connecting plate 373 and connects to the second fixing device 320; the bottom of both ends of the second connecting plate 374 is provided with slide rails 372; the slide rails 372 pass through the first connecting plate 373 and connect to the base plate 371.

[0139] The first fixing device 310 is used to fix the outer shell 110; the second fixing device 320 is used to fix the water outlet pipe 120; the lifting device 330 can move the second fixing device 320 away from or closer to the first fixing device 310; the first fixing device 310 and the second fixing device 320 can move and rotate in the horizontal direction by connecting bearings, rotary cylinders, etc.

[0140] During welding, the worker places the outer shell 110 to be welded onto the first fixing device 310 for fixation; then the welding end of the water outlet pipe 120 is placed on the corresponding position of the outer shell 110; the lifting device 330 drives the second fixing device 320 to approach the first fixing device 310 and presses the water outlet pipe 120 against the outer shell 110, thereby clamping the outer shell 110 and the water outlet pipe 120; then the central control computer is activated, the button switch 380 is turned on, the laser device 340 is turned on, and the first fixing device 310 and the second fixing device 320 drive the outer shell 110 and the water outlet pipe 120 to rotate horizontally, so that the contact part of the outer shell 110 and the water outlet pipe 120 passes through the welding area of ​​the laser device 340 to complete the welding.

[0141] The automatic laser welding equipment for faucets provided in this invention uses two fixing devices to fix the outer shell and the water outlet pipe respectively. The first and second fixing devices are rotatable to cooperate with the laser device to achieve automatic circumferential welding. Compared with the prior art, the automatic laser welding equipment for faucets provided in this invention can fix the faucet body and the water outlet pipe separately, thereby solving the problem of poor welding quality caused by slippage or positional displacement of the outer shell and the water outlet pipe during the welding process.

[0142] In specific implementation, such as Figure 11 , Figure 12 , Figure 13 As shown, the first fixing device 310 includes a first fixing body 311, a first fixing groove 312, a vertical plate 313, and a first limiting plate 314; the first fixing groove 312 is elongated; the first fixing groove 312 is located at the upper end of the first fixing body 311, and the first fixing groove 312 has openings on both sides; the vertical plate 313 is located on one side of the first fixing groove 312; the upper end of the vertical plate 313 is connected to the first limiting plate 314; the first limiting plate 314 extends horizontally into the groove of the first fixing groove 312; the bottom surface of the first limiting plate 314 has a limiting protrusion 315 along the length direction.

[0143] During welding, the worker moves the outer casing 110 from one end of the first fixing groove 312 and aligns the limiting protrusion 315 with the first limiting notch 1321 inside the outer casing 110 (e.g., Figure 13 As shown, the first limiting piece 132 inside the outer shell 110 has a first limiting notch 1321. Pushing it in allows the first limiting notch 1321 to engage with the limiting protrusion 315, thus fixing the position of the outer shell 110. This embodiment, through the structural design of the first fixing body 311, the first fixing groove 312, the upright plate 313, the first limiting plate 314, and the limiting protrusion 315, can stably fix the faucet body 110 within the first fixing groove 312, improving the overall stability of the clamping device.

[0144] In specific implementation, such as Figure 13 As shown, a bolt 316 is provided through the side wall of the upright plate 313; the threaded end of the bolt 316 is located at a position that can abut against one side wall of the outer casing 110; by rotating the bolt 316, the distance between the threaded end of the bolt 316 and the upright plate 313 can be adjusted, thereby adjusting the position of the outer casing 110 to match the welding requirements of different models and welding positions.

[0145] In specific implementation, such as Figure 13As shown, a second limiting plate 317 is provided above the first limiting plate 314 along the length direction; the length of the second limiting plate 317 is less than that of the first limiting plate 314; the upper end face of the second limiting plate 317 can abut against the upper end of the inner part of the outer shell 110, thereby further improving the stability of the outer shell 110 when it is fixed in the first fixing groove 312.

[0146] In specific implementation, the bottom of the first fixing device 310 is provided with a rotatable gripper cylinder 350; the gripper cylinder 350 is connected to the air source machine; the bottom of the gripper cylinder 350 is connected to the rotating shaft of the rotary motor or the rotating end of the rotary cylinder (not shown in the figure) to achieve rotation.

[0147] During welding, the rotatable gripper cylinder 350 drives the outer shell 110 to rotate, so that the connection between the outer shell 110 and the water outlet pipe 120 passes through the welding area of ​​the laser head 341.

[0148] In specific implementation, such as Figure 12 and Figure 14 As shown, the second fixing device 320 includes a second fixing body 321 and a second fixing groove 322. The second fixing groove 322 is vertically arranged on the side wall of the second fixing body 321. The second fixing groove 322 has an opening at one end near the first fixing device 310. The upper side wall of the second fixing body 321 is provided with a movable groove 323. The middle part of the first connecting plate 373 is provided with a movable through hole (not marked in the figure). The upper end of the second fixing body 321 passes through the movable through hole, so that the first connecting plate 373 is movably engaged in the movable groove 323. The movable end of the lifting device 330 is connected to the first connecting plate 373 and drives the first connecting plate 373 to move up and down, thereby driving the entire second fixing device 320 to move up and down.

[0149] Preferably, a bearing (not shown in the figure) is provided between the movable groove 323 and the first connecting plate 373.

[0150] In specific implementation, such as Figure 14 As shown, a positioning plate 324 is provided inside the second fixing groove 322; a groove is provided on one side wall of the positioning plate 324 facing the second fixing groove 322; the cross-section of the groove is arc-shaped; the arc of the groove is the same as the arc of the contacting water outlet pipe 120. In this embodiment, the arc-shaped design of the side wall of the positioning plate 324 can improve the stability of the second fixing device 320 when fixing the water outlet pipe 120, and increase the contact area between the upper end of the second fixing groove 322 and the water outlet pipe 120, avoiding the problem that a mark will be left on the water outlet pipe 120 after welding due to the small contact area, resulting in the substandard appearance of the water outlet pipe 120.

[0151] In specific implementation, a welding inspection device 360 ​​is also provided on one side of the first fixing device 310. The welding inspection device 360 ​​is an image inspection device. The welding inspection device 360 ​​includes a detection head 361 and a processor 362.
