Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware processing, and particularly relates to a cutting and grinding device for hardware processing. BACKGROUND

[0002] Hardware processing is a key process in manufacturing industry, which processes metal and other raw materials into various parts through mechanical means, covering cutting, forming, welding, polishing and other links. The cutting technology in hardware processing covers core processes such as turning, milling and drilling, which accurately removes metal raw materials to realize high-precision processing of complex shapes such as shafts, planes and holes. The grinding process takes abrasive wheels, sandpaper and other abrasives as the core, and gradually reduces the surface roughness through progressive processing of rough grinding, fine grinding and polishing.

[0003] According to the search, the Chinese invention patent with the publication number CN109396859A discloses a hardware processing equipment, which comprises a machine base, a processing hole horizontally arranged on the machine base, an upper chamber, a lower chamber and a polishing chamber arranged in the machine base, and the processing hole is located between the upper chamber and the lower chamber. A cutting tool is arranged in the upper chamber, and the lower part of the cutting tool extends into the upper part of the processing hole. A lifting mechanism is arranged in the lower chamber and the polishing chamber, a first fixing claw capable of fixing a pipe is arranged on the lifting mechanism in the lower chamber, a second fixing claw capable of fixing a pipe is arranged on the lifting mechanism in the polishing chamber, and the first fixing claw and the second fixing claw extend into the processing hole. The upper end of the polishing chamber is communicated with the processing hole, the second fixing claw is located in the polishing chamber, and a circular table-shaped polishing block is arranged on the two sides of the polishing chamber, and sandpaper is arranged on the polishing block. The hardware processing equipment can cut and polish the pipe.

[0004] However, when cutting hardware, especially when drawing lines on the outer wall, burrs are often left on the surface after cutting. If the burrs are not removed in time, they will directly affect the effect of texture cutting on the hardware and the precision of subsequent processing. Moreover, hardware is usually not large in size and has a complex shape with many gradient changes, which requires higher polishing precision. Ordinary polishing discs are too large in size and are not suitable for polishing hardware with multiple corners. In addition, for some continuous production operations, the workpiece often needs to be extended for cutting, but the longer the extended part, the greater the impact of the pressure on the end of the workpiece during cutting, which may even cause the workpiece to break and splash, causing production accidents and safety hazards.

[0044] With reference to Figure 9 , the buffer mechanism comprises a wheel groove 8 opened at one end of the sliding rod 64 close to the pulley 65, sliding grooves 81 symmetrically opened at positions on both sides of the sliding rod 64 close to the pulley 65, a sliding plate 82 slidably installed in the sliding grooves 81, the sliding plate 82 rotatably connected with the pulley 65, a spring two 83 fixedly installed between the sliding plate 82 and the sliding grooves 81, and a limiting block 84 fixedly installed at the bottom of the sliding grooves 81 and matched with the spring two 83; a hemispherical hole 85 is symmetrically opened on the inner side wall of the sliding grooves 81, an installation groove 86 matched with the hemispherical hole 85 is symmetrically opened on the outer side wall of the sliding plate 82, a striking ball 87 is slidably installed in the installation groove 86, and a spring three 88 is fixedly installed between the striking ball 87 and the installation groove 86.

[0045] When adjusting, the pulley 65 contacts the workpiece 21, drives the sliding plate 82 to slide and compress the spring two 83, and is in contact with the limiting block 84 to be fixed, the sliding plate 82 slides to play a buffering role, when being installed in place, the spring three 88 makes the impact ball 87 pop out of the impact half-ball hole 85 to send a reminder, so that the operator can clearly know the installation position, and ensure that the workpiece 21 is fixed properly.

[0046] With reference to Figures 1-3 The movable block 23 close to the polishing belt 38 is fixedly installed with a rack one 9, the mounting arm 32 close to the rack one 9 is fixedly installed with a gear frame 91, the gear frame 91 is rotatably installed with a gear 92 engaged with the rack one 9, the bottom of the mounting plate 3 is provided with a T-shaped groove 93, the T-shaped groove 93 is slidably installed with a T-shaped block, the bottom of the T-shaped block is fixedly installed with a rack two 94 engaged with the gear 92, the rack two 94 is fixedly installed with a connecting block 95 at one end close to the workpiece 21, the connecting block 95 is rotatably installed with a cleaning arm 96 in symmetry, and a torsional spring is arranged between the cleaning arm 96 and the connecting block 95; the machine tool 1 is provided with a scrap storage groove, the machine tool 1 is provided with a scrap falling port 97, and the scrap storage groove is slidably installed with a scrap collecting box 98;

[0047] When the polishing belt 38 moves to the workpiece 21, the gear 92 is driven to move along the rack one 9, the rack two 94 is relatively moved by twice the distance, when the polishing belt 38 moves to the middle of the machine tool 1, the rack two 94 drives the cleaning arm 96 to the far end of the scrap falling port 97 to push the scrap into the scrap storage groove, when resetting, the cleaning arm 96 sweeps back, and the scrap is cleaned to the near end of the scrap falling port 97 and falls into the scrap storage groove, when processing is finished, the scrap is taken out by the scrap collecting box 98 for recycling, and the scrap is cleaned synchronously during processing, and the normal use of equipment is protected.

[0048] The specific working principle of the application is as follows:

[0049] In use, the workpiece 21 is clamped on the mounting frame 2 on the machine tool 1, the workpiece 21 is driven to rotate, the movable block 23 is moved to the position to be machined along the slide rail 22 as required, the position of the cutting tool 26 is adjusted through the movable plate 25, and the workpiece is machined, at the same time, the movable block 23 on the other side is moved to the same position, the mounting plate 3 can move towards the workpiece 21 under the drive of the telescopic rod 31, and the polishing belt 38 is close to the workpiece 21 to polish the workpiece and timely remove burrs generated by cutting. The width of the polishing belt 38 is small, so the polishing belt 38 can adapt to hardware workpieces 21 with variable shapes and complex structures, and the polishing belt 38 can be moved to the corresponding position for polishing as required. At the same time, the polishing belt 38 is vertically arranged and has a relatively long length, so it can adapt to workpieces 21 of different sizes. Since the polishing belt 38 is stationary and the workpiece 21 moves relative to the polishing belt 38, the position of the polishing belt 38 for polishing is consumed quickly, and when it needs to be replaced, only the drive motor 36 needs to be started, the motor rotates to drive the polishing belt 38 to be pulled out from the winding box 37 along the roller 34, so that the polishing belt 38 can be quickly replaced, continuous machining operation is facilitated, and the problem of frequent shutdown and replacement due to consumption of the polishing belt 38 is avoided.

[0050] When the polishing belt 38 is polishing, the workpiece 21 does not contact the polishing belt 38 at first, at this time, the spring 46 pulls the pawl 43 and drives the ratchet 42 to be located at the position of the baffle 47, when the workpiece 21 contacts and extrudes the polishing belt 38, under the action of the workpiece 21, the polishing belt 38 drives the winding shaft 41 to rotate and drives the ratchet 42 to rotate, and the pawl 43 is pushed to rotate to the position of the limiting column 44, at this time, a section of the polishing belt 38 is released, so that the polishing belt 38 can surround the workpiece 21 in a certain arc, increase the polishing area, improve the polishing efficiency, and separate the polishing belt 38 from the cutting tool 26, to ensure the safety of machining. When the polishing belt 38 needs to be replaced, the magnet 52 is actuated, the magnet 52 is switched to the position after being attracted by the limiting column 44 formed by the magnet, the limiting column 44 slides into the position giving way under the action of the magnetic force, at this time, the pawl 43 is not limited by the limiting column 44, the winding shaft 41 can drive the ratchet 42 to rotate, and the polishing belt 38 is released, the used polishing belt 38 is wound to the output end by the drive motor 36, when the replacement is completed, the pawl 43 is reset under the action of the spring 46, the magnet 52 is slid to the other end, at this time, the magnetic poles of the magnet 52 opposite to the limiting column 44 are switched, the limiting column 44 is popped out of the position giving way under the repulsive force, the pawl 43 is limited, so that the consumables can be replaced conveniently, quickly and safely, and the machining efficiency is improved.

[0051] When the length of the hardware to be processed is longer, the second bevel gear 71 can be rotated by rotating the operating rod 74 to drive the first bevel gear 7 to rotate, and then drive the sliding rod 64 to slide into the fixed ring 63. The three pulleys 65 jointly form a clamping action on the workpiece 21. Under the action of the pulley 65, the workpiece 21 can rotate freely while being supported at the far end of the workpiece 21 by the sliding rod 64 and the pulley 65, ensuring the stability and safety of the machining, maintaining the stability of the workpiece 21 while improving the machining precision. When the pulley 65 contacts the workpiece 21 after adjustment, it drives the sliding plate 82 to slide and compresses the second spring 83, and completes the fixation when the sliding plate 82 contacts the limiting block 84. The sliding of the sliding plate 82 relative to the sliding groove 81 provides a certain buffer effect during installation, avoiding hard contact with the workpiece 21 and causing damage to the workpiece 21. When installed in place, the ball 87 is ejected and hits the half-sphere hole 85 under the action of the third spring 88, making a crisp sound that can remind the operator that the installation is in place, ensuring that the workpiece 21 is properly fixed;

[0052] When the polishing belt 38 moves to the workpiece 21, the gear 92 is rotated and moves along the rack 9, which can make the rack 94 move twice the distance relative to the gear 92. Therefore, when the polishing belt 38 moves to the middle of the machine tool 1, the cleaning arm 96 moves to the far end of the chip falling port 97, and the debris on the machine tool 1 is pushed into the chip storage groove. When the polishing belt 38 is reset after processing, the cleaning arm 96 sweeps back to clean the debris to the near end of the chip falling port 97 and falls into the chip storage groove. When the processing is completed, the debris can be taken out by the chip collection box 98 for recycling and processing, so that the debris is cleaned at the same time as the processing, ensuring that the debris does not accumulate and protecting the normal use of the equipment. The cleaning arm 96 can rotate to avoid the connecting plate 62, and then reset under the action of the torsional spring, thereby ensuring the safety of use.

[0053] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacements or changes within the technical scope disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
