Description

Technical Field

[0001] This invention relates to the field of hardware pipe fittings technology, and in particular to a surface polishing and grinding equipment for processing hardware pipe fittings. Background Technology

[0002] Pipe fittings are an indispensable component of piping systems. They perform core functions such as connection, turning, diversion, diameter change, sealing, and support, ensuring the integrity and flexibility of the piping system. They are used for connecting pipes to each other, and include flanges, unions, clamps, compression fittings, and hose clamps. After the production of pipe fittings, their surfaces need to be ground and polished. During the production process, defects such as scratches, burrs, and oxide scale may remain on the surface of the fittings. Grinding and polishing can remove these defects, making the surface of the fittings smoother and flatter, improving the overall aesthetics. Surface polishing and grinding equipment for pipe fitting processing is used for this purpose. However, traditional surface polishing and grinding equipment for processing hardware pipe fittings generates debris during the polishing process. This debris is thrown to the bottom of the polishing area. The usual method for collecting the debris is to install a collection box at the bottom. Due to the high-speed rotation of the polishing wheel, a strong swirling airflow is generated, directly carrying the fine debris downwards. Since the collection box is installed at the bottom, the debris carried by the airflow impacts the box wall and bounces upwards along the box wall, escaping from the box opening and splashing all over the worktable, making cleaning difficult. Therefore, a surface polishing and grinding equipment for processing hardware pipe fittings is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a surface polishing and grinding equipment for processing hardware pipe fittings, in order to solve the defect that when polishing hardware pipe fittings, the polishing debris generated is easily splashed out from the bottom collection box and falls all over the worktable, making it troublesome to clean.

[0009] Preferably, hinge frames are hinged on both sides at the middle position between the connecting seat and the fixing block, a return spring is installed at the middle position between the connecting seat and the fixing block, and the bottom end of the fixing block is fixed to the top end of the mounting block.

[0010] Preferably, the hinge frame is provided in two sets, and the two sets of hinge frames are symmetrically distributed on one side of the fixed block.

[0011] Preferably, two sets of threaded sleeves are provided, and the two sets of threaded sleeves form a threaded connection with the bidirectional screw.

[0012] Preferably, a feeding structure is provided on one side of the top of the guide seat. The feeding structure includes a material box, which is installed on one side of the top of the guide seat. A feeding port is installed at the top of the material box, and support frames are fixed on both sides of the material box. A rotating roller is installed inside the material box, and a material groove is opened on the surface of the rotating roller. A feeding port is installed at the bottom of the material box.

[0013] Preferably, the material troughs are provided in multiple sets, and the multiple sets of material troughs are distributed in a ring on the surface of the rotating roller.

[0014] The present invention provides a surface polishing and grinding equipment for processing hardware pipe fittings, the advantages of which are: With a collection structure, when the polishing wheel grinds the surface of the hardware fittings, the generated debris will be thrown into the collection box. At this time, the use of a sponge, based on the softness of the sponge, can buffer the impact of the debris and avoid hard contact with the debris, so as to prevent the debris from splashing inside the collection box. Furthermore, the sponge has magnets installed inside, which can magnetically attract and fix the debris to the surface of the sponge, preventing the debris from splashing onto the workbench and making subsequent cleaning more troublesome. Furthermore, by controlling the top and bottom surfaces of the sponge to flip, the sponge’s two surfaces can be fully utilized to buffer and collect debris. After the two surfaces of the sponge have finished flipping, the reciprocating screw and the screw sleeve drive the brush seat at the top of the rotating rod to move to one side. When the brush seat moves on the surface of the bottom of the sponge, it will clean the surface of the bottom of the sponge, thereby sweeping away the debris that is sucked on the surface of the bottom of the sponge. Furthermore, when the brush holder contacts the surface of the bottom end of the sponge, due to the friction between the brush holder and the sponge surface, for example, when the brush holder moves to the left, the brush holder will tilt to the right under the action of friction. Since one end of the rotating rod is movably connected to one side of the wire sleeve, it can tilt at an angle. When the brush holder tilts, it will drive the torsion spring to deform and store energy, thereby achieving an angled cleaning of the bottom end surface of the sponge. Furthermore, during tilt cleaning, the angle of the brush holder can be limited by the connecting plate, allowing cleaning at an angle of 30°-35°. When the brush holder is tilted for cleaning, the force is decomposed into vertical pressure and horizontal tangential force, similar to shoveling soil with a shovel. The horizontal component is responsible for prying away debris, while the vertical component only maintains contact. The horizontal tangential force can efficiently peel off stubborn debris embedded in the pores of the sponge. Since the reciprocating screw can move the thread sleeve back and forth, the brush holder can perform a reciprocating cleaning on the surface of the bottom of the sponge. In addition, through the cooperation of the rotating rod and the torsion spring, the direction of the tilt angle of the brush holder can be automatically adaptively changed during the reciprocating movement of the brush holder, thereby completing the tilt cleaning of debris on the surface of the bottom of the sponge and making it more effective in cleaning debris. Furthermore, after the cleaning is completed, when the brush holder returns to its original position, the brush holder will detach from the surface of the bottom of the sponge. Because the brush holder will compress the elastic ball to store elastic potential energy when it is tilted for cleaning, and the torsion spring will be twisted when tilted, storing elastic potential energy simultaneously, when the wire sleeve returns to its original position, the brush holder will detach from the surface of the bottom of the sponge, and the brush holder will lose the friction constraint. The elastic ball compressed on one side will rebound instantly, giving the brush holder a pushing force F1 to the other side. The torsion spring releases potential energy, giving the brush holder a restoring force F2 to the other side. F1+F2 together push the brush holder to swing back to the other side. When the brush holder swings back to the other side, it will compress the elastic ball on the other side. The elastic ball on the other side will immediately rebound after being compressed, giving the brush holder a rebound force F3 to one side. Through repeated swinging, the potential energy is exhausted, thereby driving the brush bristles on the brush holder to vibrate at high frequency, shaking off the debris embedded in the gaps of the bristles, and automatically completing the cleaning work of the debris embedded in the gaps of the bristles. With an adjustable structure, when the hardware fitting falls to the top of the guide seat, the two-way screw and the two sets of screw sleeves work together to drive the polishing wheel and the guide wheel to move to the middle position at the same time, so that the distance between them can be adjusted, allowing it to polish and grind hardware fittings of different sizes. After the distance between the polishing wheel and the guide wheel is adjusted. Furthermore, during position adjustment, the polishing wheel compresses the return spring to contract. Over time, the polishing wheel's surface wears down, reducing its diameter. The return spring, using its elasticity, pushes the polishing wheel towards the pipe, automatically compensating for wear gaps and maintaining stable contact pressure between the polishing wheel and the pipe. This prevents the polishing wheel from becoming looser and the polishing effect from deteriorating. The combination of adjustable spacing via a two-way screw and adaptive polishing wheel distance allows for a wide range of compatibility with different pipe diameters while compensating for wear on the polishing wheel. This solves the compatibility problem for different pipe sizes and ensures stable polishing pressure, thus completing the adjustment process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-15 The present invention provides a surface polishing and grinding equipment for processing hardware pipe fittings, including a worktable 1 and a guide seat 2; A guide seat 2 is installed at the middle position of the top of the workbench 1. An adjustment structure 3 is provided on both sides of the guide seat 2. A pusher cylinder 5 is installed on one side of the guide seat 2. A collection structure 6 is installed on one side of the bottom of the guide seat 2. See Figures 1-8 The adjusting structure 3 includes a bidirectional screw 304, which is installed in the middle position inside the workbench 1. Screw sleeves 305 are installed on the outer sides of both ends of the bidirectional screw 304. A connecting block 307 is installed on the top of the screw sleeve 305 on one side of the bidirectional screw 304. A guide wheel 302 is installed on the top of the connecting block 307. An installation block 306 is fixed on the top of the screw sleeve 305 on the other side of the bidirectional screw 304. A polishing wheel 301 is installed on the top of the installation block 306. A connecting seat 3011 is fixed on one side of the bottom end of the polishing wheel 301. A fixing block 308 is installed on one side of the connecting seat 3011. Grooves 303 are opened on both sides of the middle position of the guide seat 2. The collection box 601 is installed at the bottom end of the groove 303. Hinges 3010 are hinged on both sides at the middle position between the connecting seat 3011 and the fixing block 308. A return spring 309 is installed at the middle position between the connecting seat 3011 and the fixing block 308. The bottom end of the fixing block 308 is fixed to the top end of the mounting block 306. Two sets of hinge frames 3010 are provided, and the two sets of hinge frames 3010 are symmetrically distributed on one side of the fixed block 308. Two sets of threaded sleeves 305 are provided, and the two sets of threaded sleeves 305 form a threaded connection with the bidirectional screw 304. A feeding structure 4 is provided on one side of the top of the guide seat 2. The feeding structure 4 includes a material box 402. The material box 402 is installed on one side of the top of the guide seat 2. A feeding port 401 is installed at the top of the material box 402. Support frames 403 are fixed on both sides of the material box 402. A rotating roller 405 is installed inside the material box 402. A material groove 404 is opened on the surface of the rotating roller 405. A feeding port 406 is installed at the bottom of the material box 402. Multiple sets of material troughs 404 are provided, and the multiple sets of material troughs 404 are distributed in a ring on the surface of the rotating roller 405.

[0019] Specifically, in this embodiment, when polishing the surface of the hardware fittings, the hardware fittings are placed inside the feed inlet 401 by the feeding mechanism. After placement, a motor on one side is started to drive the rotating roller 405 to rotate. As the rotating roller 405 rotates, the hardware fittings fall into the material trough 404. As the rotating roller 405 rotates, when the material trough 404 containing the hardware fittings moves to the bottom of the discharge port 406, the hardware fittings will fall to the top of the guide seat 2 due to gravity. By using multiple sets of material troughs 404, the hardware fittings are evenly fed, so that when polishing the surface of the hardware fittings, too much material is fed at one time, which will affect the polishing work. When the metal fitting falls to the top of the guide seat 2, the pusher cylinder 5 is activated to push the metal fitting to one side at the top of the guide seat 2, realizing automatic pushing. Before polishing the surface of the metal fitting, the distance between the polishing wheel 301 and the guide wheel 302 is adjusted according to the size of the metal fitting. While adjusting the distance between the polishing wheel 301 and the guide wheel 302, the motor on one side of the bidirectional screw 304 is activated to drive the bidirectional screw 304 to rotate. When the bidirectional screw 304 rotates, it will cooperate with the two sets of threaded sleeves 305, thereby... The polishing wheel 301 and the guide wheel 302 are moved to the middle position simultaneously to adjust their distance, so that they can polish and grind hardware fittings of different sizes. After the distance between the polishing wheel 301 and the guide wheel 302 is adjusted, the polishing wheel 301 and the guide wheel 302 are started to rotate. When the hardware fitting passes the middle position between the polishing wheel 301 and the guide wheel 302, the rotating polishing wheel 301 will rotate and grind the surface of the hardware fitting, thereby realizing the polishing and grinding work of the surface of the hardware fitting. When the polishing wheel 301 is adjusted, it compresses the return spring 309 to contract. Over time, the surface of the polishing wheel 301 will wear down and its diameter will decrease. At this time, the return spring 309 will push the polishing wheel 301 towards the pipe fitting based on its own elastic force, automatically compensating for the wear gap and maintaining a stable contact pressure between the polishing wheel 301 and the pipe fitting. This avoids the situation where the polishing becomes looser and the polishing effect deteriorates with polishing. Through the combination of the adjustment distance of the bidirectional screw 304 and the adaptive distance of the polishing wheel 301, it can accommodate a wide range of hardware pipe fitting diameters and compensate for the wear of the polishing wheel 301 in a small range. This solves the compatibility problem of hardware pipe fittings of different specifications and ensures the stability of polishing pressure, thus completing the adjustment work.

[0020] See Figures 9-15 The collection structure 6 includes a collection box 601, which is installed on one side of the bottom of the guide seat 2. A collection box 606 is installed inside the collection box 601. A first fixing plate 602 is installed at one end of one side of the collection box 601. A reciprocating screw 604 is installed at one end of the first fixing plate 602. A second fixing plate 607 is installed at one end of the reciprocating screw 604. The bottom end of the second fixing plate 607 is fixed to the top end of the worktable 1. A thread sleeve 6011 is installed on the outer side of one end of the reciprocating screw 604. A rotating rod 605 is movably connected to one end of the thread sleeve 6011. A brush seat 6014 is fixed at the top end of the rotating rod 605. A torsion spring 6012 is installed on the outer side of one end of the rotating rod 605. A connecting plate 6013 is installed at both ends of one side of the thread sleeve 6011. An elastic ball 6015 is installed on the surface of one side of the connecting plate 6013. A sponge 608 is installed inside the collection box 601. A magnet 609 is installed inside the sponge 608. A guide block 6010 is installed on one side of the threaded sleeve 6011. A guide rail 603 is installed at the middle position of the second fixing plate 607 and the first fixing plate 602. The guide block 6010 is inserted into the interior of the guide rail 603, and a guide connection is formed between the guide block 6010 and the guide rail 603. Two sets of connecting plates 6013 are provided, and the two sets of connecting plates 6013 are symmetrically distributed on both sides of the rotating rod 605; One end of the torsion spring 6012 is fixed to one side of the threaded sleeve 6011, and the other end of the torsion spring 6012 is fixed to the surface of one end of the rotating rod 605. The elastic balls 6015 are arranged at equal intervals on one side of the connecting plate 6013.

[0021] Specifically, in this embodiment, when the polishing wheel 301 polishes the surface of the hardware fittings, the generated debris is thrown into the collection box 601. At this time, the use of the sponge 608 allows the debris to be cushioned when it comes into contact with the surface of the sponge 608, based on the softness of the sponge 608, thus avoiding hard contact with the debris and preventing the debris from splashing inside the collection box 601. This completes the cushioning and collection of debris. In addition, the sponge 608 is equipped with a magnet 609, which can magnetically fix the debris to the surface of the sponge 608 by using the magnetic properties of the magnet 609, so that the debris will not splash when it falls onto the surface of the sponge 608, thus preventing the debris from splashing onto the surface of the workbench 1 and making it more troublesome to clean later. After the sponge 608 has collected debris for a period of time, the sponge 608 is set to rotate 180° at a time via the control panel. The motor controls the flipping of the upper and lower surfaces of the sponge 608, fully utilizing the buffering and collection capabilities of both surfaces. Once the two surfaces of the sponge 608 have finished flipping, the micro motor at one end of the reciprocating screw 604 is activated, driving the screw to rotate. During rotation, the reciprocating screw 604, through its interaction with the thread sleeve 6011, moves the brush holder 6014 at the top of the rotating rod 605 to one side. Because the guide block 6010 on one side of the thread sleeve 6011 slides inside the guide rail 603, it guides the thread sleeve 6011, allowing it to move on the surface of the reciprocating screw 604. When the brush holder... As brush holder 6014 moves across the surface of the bottom end of sponge 608, it cleans the surface, removing debris. When brush holder 6014 contacts the surface of the bottom end of sponge 608, friction causes it to tilt to the right, for example, when it moves to the left. Since one end of rotating rod 605 is movably connected to one side of thread sleeve 6011, this tilting is possible. Furthermore, the tilting of brush holder 6014 causes the torsion spring 6012 to deform and store energy, thus achieving the tilting angle during cleaning of the bottom end of sponge 608. When tilted, the angle of the brush holder 6014 can be limited by the connecting plate 6013, allowing cleaning at an angle of 30°-35°. When the brush holder 6014 is tilted for cleaning, the force is decomposed into vertical pressure and horizontal tangential force, similar to shoveling soil. The horizontal component is responsible for prying away debris, while the vertical component only maintains contact. The horizontal tangential force can efficiently remove stubborn debris embedded in the pores of the sponge 608. If the brush holder 6014 is used for vertical cleaning, the bristles press vertically against the surface of the sponge 608, and the direction of the force during scraping is perpendicular to the surface. Most of the force is absorbed by the elasticity of the sponge 608, similar to poking dough vertically with chopsticks, making it difficult to pry away embedded debris. This results in debris residue affecting the cleaning effect. Because the reciprocating screw 604 can... The reciprocating movement of the wire sleeve 6011 allows the brush holder 6014 to perform a reciprocating cleaning of the bottom surface of the sponge 608. Through the cooperation of the rotating rod 605 and the torsion spring 6012, the brush holder 6014 automatically adapts its tilt angle during reciprocating movement, thus completing the cleaning of debris from the sponge 608 surface and improving cleaning efficiency. The cleaned debris falls into the collection box 606 for collection. After cleaning, when the brush holder 6014 returns to its original position, it detaches from the bottom surface of the sponge 608. Because the brush holder 6014 compresses the elastic ball 6015 to store elastic potential energy during tilting and cleaning, this process is effective.Furthermore, when tilted, the torsion spring 6012 will twist, simultaneously storing elastic potential energy. When the thread sleeve 6011 returns to its original position, the brush holder 6014 will detach from the surface of the bottom end of the sponge 608, causing the brush holder 6014 to lose the constraint of friction. At this time, the elastic ball 6015 compressed on one side will rebound instantly, giving the brush holder 6014 a pushing force F1 to the other side. The torsion spring 6012 releases its potential energy, giving the brush holder 6014 a restoring force F2 to the other side. F1 + F2 together push the brush holder 6014 to the other side. When the brush holder 6014 swings back to the other side, it compresses the elastic ball 6015 on the other side. The compressed elastic ball 6015 immediately rebounds, giving the brush holder 6014 a rebound force F3 to one side. Through repeated oscillations, the potential energy is exhausted, thereby causing the brush bristles on the brush holder 6014 to vibrate at high frequency, shaking off debris embedded in the bristle gaps. This automatically completes the cleaning of debris embedded in the bristle gaps. The brush holder can be removed after the hardware fittings have been polished and ground, thus completing the automatic polishing and grinding process for the hardware fittings.
