Description

Technical Field

[0001] This utility model relates to the field of faucet valve body assembly technology, and in particular to a faucet valve body assembly machine. Background Technology

[0002] In the faucet manufacturing process, valve body assembly is one of the core steps, and its efficiency and precision directly affect the quality of the product and the final product.

[0003] Existing valve body assembly machines typically require the use of limiting fixtures on the valve core body to ensure installation accuracy during valve body assembly. However, these limiting fixtures are generally set to a single station, which necessitates frequent loading and unloading of individual fixtures. Over time, this leads to fixture wear. Furthermore, single-station limiting fixtures can only hold one valve core at a time, requiring the completion of the entire process of loading, assembly, and unloading before the next operation can proceed, resulting in a significant time gap and reduced efficiency. Utility Model Content

Each limiting component includes a mounting plate movably inserted into the rotary table, a support platform fixed to the mounting plate, and a placement groove and an extension plate on the surface of the support platform. A pneumatic clamp is fixedly mounted on the surface of the extension plate. When the rotary table rotates, the two limiting components can alternately switch to the position below the assembly station.

[0007] Preferably, the servo motor is a Panasonic MINAS A6, and the precision reducer is a Harmonic Drive SHG-20-100-2UH. The servo motor and the precision reducer are connected by a flange and a locating pin, and the coaxiality error is less than or equal to 0.02 mm.

[0013] Preferably, a hinge plate is hinged to the surface of the end of the slide away from the vertical groove, and the end of the hinge plate away from the slide is hinged to the long strip.

[0014] The effects achieved by the above components are as follows: the setting of the limiting rod and the limiting hole enables the mounting plate to be limited inside the rotary table; the setting of the electric telescopic rod enables the sliding plate to move inside the vertical groove; and the setting of the hinge plate enables the long strip plate to move on the outer wall of the sliding rod.

[0018] Example 1, as Figure 1-4 As shown, a faucet valve body assembly machine includes a support platform 1, with two mounting ears 4 fixedly installed on both sides of the support platform 1, and a dual-station rotary switching device 2 provided on the surface of the support platform 1.

[0019] Referring to Figure 1, in this embodiment: the dual-station rotary switching device 2 includes a servo motor 21 fixedly mounted on the surface of the support platform 1. A precision reducer 22 is fixedly mounted on the output end of the servo motor 21 via a coupling. A rotary table 23 is fixedly mounted on the output end of the precision reducer 22 via a coupling, allowing rotation around an axis. Two limiting components are symmetrically arranged on the rotary table 23. Each limiting component includes a mounting plate 24 movably inserted inside the rotary table 23, a support platform 25 fixed to the mounting plate 24, and a placement groove 26 and an extension plate 27 on the surface of the support platform 25. A pneumatic clamp 28 is fixedly mounted on the surface of the extension plate 27. When the rotary table 23 rotates, the two limiting components can alternately switch to the position below the assembly station. The servo motor 21 is a Panasonic MINAS. The precision reducer 22, model A6, is "Harmonic Drive SHG-20-100-2UH". The servo motor 21 and the precision reducer 22 are connected by a flange and a locating pin, with a coaxiality error of less than or equal to 0.02 mm. The mounting plate 24 and the rotary table 23 are connected by a dovetail groove sliding fit, with a sliding stroke of 30 to 50 mm and a fit clearance of less than or equal to 0.1 mm. The clamping force range of the pneumatic clamp 28 is 50 to 150 N. The pneumatic clamp 28 has a built-in pressure sensor with a detection accuracy error of 5 N, which allows the rotary table 23 to rotate, thereby driving the two limit components to switch alternately to the bottom of the assembly station. This allows the assembly of two valve bodies to be completed in a single cycle, thereby improving the efficiency of the device and reducing the wear of the pneumatic clamp 28 of the individual limit components.

[0020] Reference Figure 3-4 As shown in this embodiment, the side of the rotary table 23 is provided with a limiting device 3 to limit the mounting plate 24 within it. The limiting device 3 includes two sliding rods 301 fixedly installed on the side of the rotary table 23 and a long strip plate 302 that slides between them. Two limiting rods 303 are fixedly installed on the surface of the long strip plate 302. The sides of the two mounting plates 24 are each provided with limiting holes 304 that match the limiting rods 303. A limiting plate 305 is fixedly installed on the surface of the sliding rod 301 away from the rotary table 23. The limit hole 304 and the limit hole 303 are fitted with an H-seven / G-six clearance fit. The limit device 3 also includes an L-shaped bracket 306 fixedly installed on the top surface of the rotary table 23. The inner wall surface of the vertical end of the L-shaped bracket 306 is provided with a vertical groove 307 and a sliding plate 308 inside it. The bottom horizontal end of the L-shaped bracket 306 is fixedly installed with an electric telescopic rod 309 for driving the sliding plate 308 to slide inside the vertical groove 307. The stroke of the electric telescopic rod 309 is 20 mm and the positioning accuracy error is 0.2 mm. A hinge plate 310 is hinged to the surface of the end of the slide plate 308 away from the vertical groove 307. The end of the hinge plate 310 away from the slide plate 308 is hinged to the long strip plate 302. The setting of the limiting rod 303 and the limiting hole 304 serves to limit the mounting plate 24 inside the rotary table 23. The setting of the electric telescopic rod 309 serves to drive the slide plate 308 to move inside the vertical groove 307. The setting of the hinge plate 310 serves to drive the long strip plate 302 to move on the outer wall of the slide rod 301.

[0021] Working principle: When the device is needed, firstly, the support platform 1 is fixed in a suitable position using the four mounting ears 4. Then, the valve core body is placed inside the placement groove 26. Next, the pneumatic clamp 28 is activated to clamp and fix the valve core body inside the placement groove 26. At this time, the assembly station performs the corresponding assembly work. When the assembly station is assembling, another valve core body can be placed inside the placement groove 26 for limit operation. After the assembly fixture is assembled, the servo motor 21 and the precision reducer 22 are activated simultaneously to make the rotary table 23 rotate. When rotation occurs, it drives the mounting plate 24 to rotate, which in turn drives the support platform 25 to rotate. The support platform 25 then drives the valve core body to rotate below the assembly station, continuing the assembly operation. To make the entire operation process more precise, a PLC controller can be used to electrically connect the pneumatic clamp 28, servo motor 21, and precision reducer 22. The PLC controller presets the action sequence: the servo motor 21 drives the rotary table 23 to rotate 180 degrees, which takes two seconds; the arrival signal triggers the pneumatic clamp 28 to complete clamping in 0.5 seconds; and the assembly station simultaneously performs pressing, which takes five seconds, forming an eight-second cycle. The production cycle, through the coordination of the above structures, allows the rotary table 23 to rotate, thereby driving the two limit components to alternately switch to the lower part of the assembly station. This allows the assembly of two valve bodies to be completed in a single cycle, thus improving the efficiency of the device and reducing the wear of the pneumatic clamp 28 of each limit component. When it is necessary to replace the corresponding limit component according to the size of the valve core body, the electric telescopic rod 309 can be activated. The activation of the electric telescopic rod 309 drives the slide plate 308 to move inside the vertical groove 307. The movement of the slide plate 308 inside the vertical groove 307 drives the hinge plate 310 to move. The movement of the hinge plate 310 pushes the long The strip 302 moves on the surface of the slide bar 301. The movement of the strip 302 on the surface of the slide bar 301 drives the limiting rod 303 to move. The movement of the limiting rod 303 causes it to move out of the limiting hole 304. The separation of the limiting rod 303 and the limiting hole 304 causes the mounting plate 24 to lose its limit inside the rotary table 23. At this time, the mounting plate 24 can be pulled out from the inside of the rotary table 23 to complete the corresponding disassembly operation. Then, the limiting component of the corresponding size can be replaced. Through the cooperation of the above structure, the limiting component can be replaced according to the size of the valve core body, which improves the fit of the device when clamping the limiting valve core body.
