Description

Technical Field

[0001] This utility model relates to the field of hardware parts processing technology, specifically a grinding device for hardware parts processing. Background Technology

[0002] Hardware components typically include various metal products and accessories. A bushing is a cylindrical mechanical part fitted onto a rotating shaft, primarily used to reduce wear on the shaft and its housing, protect the journal from damage, and extend the shaft's service life. Bushings are usually made of copper, stainless steel, or other metal materials, possessing high wear resistance and corrosion resistance.

[0003] Based on the above, the inventors have discovered the following problems: When polishing hardware bushings, the surface of the hardware bushings is usually polished manually by hand with sandpaper. Manual polishing can only polish the surface of one hardware bushing at a time, thus reducing the polishing efficiency of hardware bushings.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a grinding device for processing hardware parts, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding device for processing hardware parts, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A grinding device for processing hardware parts includes a support mechanism. The support mechanism includes a base, which is hollow, and a placement mechanism is provided at the center of the base. The placement mechanism includes a square base, the upper end of which has a pair of insertion slots. Each of the insertion slots is connected to a mounting seat. The bottom of each mounting seat is connected to five rotating shafts via bearings. The upper ends of each of the five rotating shafts pass through the mounting seat and are connected to a placement seat. The outer side of the placement seat has four moving slots. One end of each of the four moving slots is slidably provided with a moving block, and the inner sidewall of each of the four moving slots is connected to a support rod. The end of the support rod away from the inner wall of the placement seat passes through the moving block and extends into the interior, and is connected to a stop block. A spring is sleeved on the outer side of the support rod, and the two ends of the spring are respectively connected to the outer sidewall of the moving block and the inner sidewall of the moving slot.

[0008] Furthermore, the diameter of the stop block is larger than the diameter of the support rod, one end of the stop block is arc-shaped, and the other end of the stop block is in contact with one side of the inner wall of the moving block.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since the diameter of the stop block is larger than the diameter of the support rod, the moving block is prevented from separating from the support rod. When the moving block is squeezed into the moving groove, the moving block moves on the support rod, and at the same time, the distance between the arc-shaped end of the moving block and the arc-shaped end of the stop block becomes smaller.

[0010] Furthermore, each of the five rotating shafts is fitted with a worm gear near its bottom end. A pair of fixing plates are connected inside the mounting base, and a worm is connected between the pair of fixing plates via a bearing. The worm meshes with the five worm gears.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the worm and worm wheel, when the worm rotates, it is easy to drive the five worm wheels to rotate, thereby realizing the rotation of the five shafts.

[0012] Furthermore, a first motor is mounted on the outer wall of one of the fixed plates, and the output end of the first motor is connected to the worm gear for transmission.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting up a first motor, it is easier to drive the worm gear to rotate when the first motor is started.

[0014] Furthermore, a grinding mechanism is provided on both sides of the upper end of the square base. The grinding mechanism includes a support plate, which is L-shaped and the bottom end of the support plate is attached to the upper end of the square base. A pair of connecting plates are provided on the upper end of the support plate, the bottom end of one of the connecting plates is connected to the inner bottom end of the support plate, and a pair of grinding rollers are rotatably connected between the pair of connecting plates. A grinding belt is wound around the outside of the pair of grinding rollers.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting a pair of connecting plates, it is convenient to install a pair of grinding rollers, and a grinding belt is wrapped around the outside of the pair of grinding rollers. When one of the grinding rollers rotates, the other grinding roller will rotate under the action of the grinding belt, so that the grinding belt grinds the surface of the hardware bushing.

[0016] Furthermore, a second motor is mounted on the upper side of one of the connecting plates, and the output end of the second motor is connected to one of the grinding rollers via a transmission connection.

[0017] The advantage of adopting the above-mentioned further solution is that by setting a second motor, it is convenient to drive one of the grinding rollers to rotate when the second motor is started.

[0018] Furthermore, the upper surface of the base is provided with a protective mechanism, which includes a protective cover. The bottom end of the protective cover is connected to the upper end of the base, and a protective door is hinged to one side of the upper end of the protective cover. A second magnetic strip is connected to the front of the protective door, and a first magnetic strip is connected to the upper surface of the base. The first magnetic strip and the second magnetic strip are magnetically attracted to each other.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting up a protective mechanism, the dust generated during grinding is prevented from escaping into the air. By hinged a protective door on one side of the upper end of the protective cover, when the protective door is closed, the second magnetic strip on the front of the protective door is brought into contact with the first magnetic strip on the upper end of the base. Since the magnetic poles between the first magnetic strip and the second magnetic strip are different, the first magnetic strip and the second magnetic strip are attracted to each other.

[0020] Furthermore, a pair of electric telescopic rods are installed on both outer sides of the protective cover. The movable ends of the pair of electric telescopic rods on the same side penetrate the protective cover and are connected to the support plate.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by setting up electric telescopic rods, the number of electric telescopic rods is two pairs, and the movable end of the pair of electric telescopic rods on the same side is connected to its adjacent support plate. When the two pairs of electric telescopic rods are started, it is convenient to adjust the distance between the pair of support plates, so that the opposite sides of the pair of grinding sanding belts can fit well with the surface of the hardware bushing.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The grinding device for processing hardware parts has a hollow base, which facilitates the installation of a square seat at the center of the base. A pair of insertion slots are opened on the square seat, which facilitates the connection of a pair of mounting seats to the square seat through the insertion slots. There are five rotating shafts inside one mounting seat, and each rotating shaft is connected to a placement seat at its upper end. When the operator presses the moving block into the moving slot, the moving block moves on the support rod and presses the spring, so that the moving block is placed into the moving slot. Then the operator puts the bushings on the outside of the placement seats in sequence, and then releases the four moving blocks, so that they are reset under the elastic force of the spring. Since the diameter of the stop block is larger than the diameter of the support rod, the moving block is prevented from separating from the support rod, so that the end of the moving block away from the moving slot abuts against the inner wall of the bushing, so that the surfaces of multiple hardware bushings can be ground simultaneously.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a grinding device for processing hardware parts, including a support mechanism 100. The support mechanism 100 includes a base 1001, which is hollow. A placement mechanism 200 is provided at the center of the base 1001. The placement mechanism 200 includes a square seat 2001. A pair of insertion slots 2002 are provided at the upper end of the square seat 2001. Each pair of insertion slots 2002 is connected to a mounting seat 2003. The bottom of each mounting seat 2003 is connected to five rotating shafts 2004 via bearings. The upper end of each of the four components 04 passes through the mounting base 2003 and is connected to a placement base 2005. The placement base 2005 has four movable slots 2006 on its outer surface. One end of each of the four movable slots 2006 is slidably fitted with a movable block 2007. The inner sidewalls of each of the four movable slots 2006 are connected to a support rod 2008. The end of the support rod 2008 away from the inner wall of the placement base 2005 extends through the movable block 2007 and is connected to a stop block 2010. A spring 2009 is sleeved on the outside of the support rod 2008. The two ends of the spring 2009 are respectively connected to the outer sidewall of the movable block 2007. The inner wall of the moving groove 2006 is connected to the base 1001, which is hollow, to facilitate the installation of the square seat 2001 at the center of the base 1001. A pair of insertion slots 2002 are provided on the square seat 2001, allowing a pair of mounting seats 2003 to connect to the square seat 2001 via the insertion slots 2002. Five rotating shafts 2004 are provided inside each mounting seat 2003, and each rotating shaft 2004 has a placement seat 2005 connected to its upper end. When the operator presses the moving block 2007 into the moving groove 2006, it causes… The movable block 2007 moves on the support rod 2008 and presses against the spring 2009, causing the movable block 2007 to be placed into the movable groove 2006. Then, the operator puts the bushings on the outside of the placement seat 2005 in sequence, and then releases the four movable blocks 2007, so that they are reset under the elastic force of the spring 2009. Since the diameter of the stop block 2010 is larger than the diameter of the support rod 2008, the movable block 2007 is prevented from separating from the support rod 2008, so that the end of the movable block 2007 away from the movable groove 2006 abuts against the inner wall of the bushing, so that the surfaces of multiple hardware bushings can be ground simultaneously.

[0031] Please see Figures 1-5This utility model provides a technical solution: the diameter of the stop block 2010 is larger than the diameter of the support rod 2008, one end of the stop block 2010 is arc-shaped, and the other end of the stop block 2010 is in contact with one side of the inner wall of the moving block 2007. Each of the five rotating shafts 2004 has a worm gear 2011 sleeved on its outer side near the bottom. A pair of fixing plates 2012 are connected inside the mounting base 2003. A worm gear 2013 is connected between the pair of fixing plates 2012 via a bearing. The worm gear 2013 meshes with the five worm gears 2011. A first motor 2014 is installed on the outer wall of one of the fixing plates 2012. The output end of the first motor 2014 is connected to the worm gear 2013 via a transmission connection. By setting the first motor 2014, when the first motor 2014 is started, it is convenient to drive the worm gear 2013 to rotate, which in turn drives the five worm gears 2011 to rotate, thereby realizing the rotation of the five rotating shafts 2004.

[0032] Please see Figures 1-5This utility model provides a technical solution: A grinding mechanism 300 is provided on both sides of the upper end of the square base 2001. The grinding mechanism 300 includes a support plate 3001, which is L-shaped. The bottom end of the support plate 3001 is fitted to the upper end of the square base 2001. A pair of connecting plates 3002 are provided on the upper end of the support plate 3001. The bottom end of one of the connecting plates 3002 is connected to the inner bottom end of the support plate 3001. A pair of grinding rollers 3003 are rotatably connected between the pair of connecting plates 3002. A grinding belt 3004 is wound around the outside of the pair of grinding rollers 3003. The upper end of the other connecting plate 3002... A second motor 3005 is installed on one side, and the output end of the second motor 3005 is connected to one of the grinding rollers 3003. A protective mechanism 400 is provided on the upper surface of the base 1001. The protective mechanism 400 includes a protective cover 4001, the bottom end of which is connected to the upper end of the base 1001. A protective door 4002 is hinged to one side of the upper end of the protective cover 4001. A second magnetic strip 4003 is connected to the front of the protective door 4002. A first magnetic strip 4002 is connected to the upper surface of the base 1001. The first magnetic strip 1002 and the second magnetic strip 4003 are magnetically attracted to each other. A pair of electric telescopic rods 500 are installed on both sides of the outer surface of the 001. The movable ends of the pair of electric telescopic rods 500 on the same side pass through the protective cover 4001 and are connected to the support plate 3001. By setting a second motor 3005, when the second motor 3005 is started, it is easy to drive one of the grinding rollers 3003 to rotate, and under the action of the grinding belt 3004, the other grinding roller 3003 is rotated, so that the grinding belt 3004 grinds the surface of the hardware bushing. By hinged to the upper side of the protective cover 4001, a protective door 4002 is connected. When the protective door 4002 is closed, the second magnetic strip 4003 on the front of the protective door 4002 is activated. The first magnetic strip 1002 at the upper end of the base 1001 is attached to the first magnetic strip 1002. Since the magnetic poles of the first magnetic strip 1002 and the second magnetic strip 4003 are different, the first magnetic strip 1002 and the second magnetic strip 4003 are attracted to each other, which prevents the dust generated by grinding from escaping into the air. By setting electric telescopic rods 500, there are two pairs of electric telescopic rods 500. The movable end of the pair of electric telescopic rods 500 on the same side is connected to the adjacent support plate 3001. When the two pairs of electric telescopic rods 500 are started, it is easy to adjust the distance between the pair of support plates 3001, so that the opposite sides of the pair of grinding belts 3004 can be well attached to the surface of the hardware bushing.

[0033] Specifically, the working principle of this grinding device for processing hardware parts is as follows: First, the operator presses the moving block 2007 into the moving groove 2006, causing it to move on the support rod 2008 and press against the spring 2009, thus placing the moving block 2007 into the moving groove 2006. Then, the operator sequentially places the bushings onto the outside of the placement seat 2005. Next, the operator releases the four moving blocks 2007, allowing them to reset under the elastic force of the spring 2009. Since the diameter of the stop block 2010 is larger than the diameter of the support rod 2008, separation of the moving block 2007 from the support rod 2008 is prevented. This causes the end of the moving block 2007 away from the moving groove 2006 to abut against the inner wall of the bushing, thereby fixing multiple hardware bushings. Then, the protective door 4002 is closed, causing the second magnetic strip 4003 on the front of the protective door 4002 to contact the first magnetic strip 1002 at the upper end of the base 1001. Because the magnetic poles of the first magnetic strip 1002 and the second magnetic strip 4003 are different, they attract each other, preventing dust generated during grinding from escaping into the air. Then, the two pairs of electric telescopic rods 500 are activated to adjust the distance between the pair of support plates 3001, ensuring good contact between the opposing surfaces of the pair of grinding belts 3004 and the surfaces of the hardware bushings. The first motor 2014 is activated to drive the worm gear 2013 to rotate, which in turn drives the five worm wheels 2011, thus rotating the five rotating shafts 2004. Simultaneously, the second motor 3005 is activated to drive one of the grinding rollers 3003 to rotate, and under the action of the grinding belts 3004, the other grinding roller 3003 rotates. This allows the pair of grinding belts 3004 to simultaneously grind the surfaces of multiple hardware bushings, improving grinding efficiency.
