Description

Technical Field

[0001] The invention relates to the technical field of polishing and rust removal devices, and more specifically, to a polishing and rust removal device for mechanical parts used in mechanical processing. Background Art

[0002] Mechanical parts used for machining refer to the parts that make up the machine, which are mainly divided into general parts and special parts, such as gears, bearings and specific propellers. After long-term use, the surface of mechanical parts will react with the air to rust. The mechanical parts need to be polished and rusted before they can be installed and used again, which has the effect of extending the life and accuracy of mechanical parts.

[0003] And because the mechanical parts used for machining are of different sizes and irregular shapes, it is not convenient to polish them in a fixed way. The main method is to rotate the drum, and use the abrasive and the mechanical parts to roll and rotate with each other to grind, polish and remove rust from the mechanical parts. After the rolling and grinding is completed, the mechanical parts need to be washed out from the abrasive. Since the mechanical parts are of different sizes and the mechanical parts are mixed in the abrasive, it is easy to pick up the abrasive and take it out along with the mechanical parts. It can be seen that it is too troublesome to pick up the mechanical parts manually, and the rust after polishing and rust removal will be mixed in the abrasive. The magnetism of rust is relatively small and it is not easy to be absorbed and cleaned by the magnet, and then the rust will be dispersed and mixed in the abrasive. Since the rust is relatively sharp, the next time the mechanical parts are polished, too much rust will easily scratch the mechanical parts and affect the polishing of the mechanical parts. After the polishing is completed, it is too cumbersome and inconvenient to pour out the abrasive again to screen the rust, and the rust will easily affect the polishing of the mechanical parts next time. Summary of the invention

[0004] The technical solution adopted by the present invention to achieve the technical purpose is: a mechanical parts polishing and rust removal device for mechanical processing, the structure of which includes a frame, a drum polisher, a base, a bearing block, and a motor, the motor is installed at the upper end of the frame, the middle of the drum polisher is connected to the inside of the motor and is rotatably matched, the drum polisher is limited and movable and rotated at the position of the bearing block, and two bearing blocks are welded to the upper end of the base, respectively at the left and right sides of the drum polisher; The drum polishing machine comprises a rotating rod that penetrates the cylinder body, the rotating rod is inserted into the cylinder body from the outside to the inside, the guiding mechanism is in unidirectional sliding cooperation with the outer side of the rotating rod inside the cylinder body, the cabinet door hinge is installed on the outer side of the cylinder body, the outer side of the rotating rod is embedded with the motor at the same horizontal position, the left and right ends of the rotating rod are horizontally limited and rotated at the bearing block position, the rotating rod is at the central axis position of the regular hexagonal cylinder body, and when the motor drives the operation, the rotating rod and the cylinder body are driven by the motor to rotate and cooperate between the two bearing blocks; The cylinder is provided with a metal plate and a closing plate. The hexagonal metal plate and two opposite closing plates are welded to each other to form a cylinder. Only the closing plate on the side away from the motor is provided with a bearing ring between the two closing plates. The outer side of the rotating rod is welded to one of the closing plates and passes through the middle position of the opposite bearing ring. One end of the rotating rod is close to the closing plate and slides with the inner side of the bearing ring. When the rotating rod rotates, the metal plate is driven to rotate through the welded closing plate. The inner and outer layers of the bearing ring are respectively movable with the outer side of the rotating rod and the inner side of the closing plate bearings, and the transition gap between the bearing ring and the closing plate is small.

[0005] As a further improvement of the present invention, the guiding mechanism comprises a splint that is hinged at the outer end of the sliding tube, and the sliding tube can only be movable in one direction on the outer side of the rotating rod, and the splint and the connecting plate are hingedly connected together by a hinge buckle, and a filter plate is respectively provided in the middle of the splint and the connecting plate, and the movable angle of the top angle between the connecting plate and the splint is 60 degrees to 180 degrees, and the lower end of the connecting plate is hinged with the force-bearing structure, and when the bearing ring rotates counterclockwise, the outer end position of the force-bearing structure is guided to the edge of the closing plate in an arc-shaped sliding manner near the middle position inside the bearing ring, and a plane is formed between the connecting plate and the splint by the hinge buckle, and the lower end of the force-bearing structure is in contact with the inner side of the metal plate, and when the connecting plate and the splint in a planar state rotate, the mechanical parts and the abrasive are driven to their surface, and through the two filter plates on the connecting plate and the splint, the mechanical parts are blocked and stay on the surface of the connecting plate and the splint, and the smaller abrasive falls and separates from the two filter plate positions under gravity; As a further improvement of the present invention, the bearing ring is provided with an arc groove and a bearing body on one side inside the closing plate position, wherein the force-bearing structure is guided to slide at the arc groove position, and a protruding handle is provided on the outside of the bearing body so that it can be manually rotated for cooperation, and an inward-recessed groove is provided on the edge and the inner side of the bearing body, and the inward-recessed groove is used for rolling and rotating cooperation with the closing plate and the rotating rod after the ball is engaged and limited, and there is a transition cooperation between the outer side of the bearing body and the closing plate and the rotating rod. Therefore, when the sliding tube is driven by the rotating rod to rotate counterclockwise, the connecting plate is squeezed inward at the bearing body position, so that the connecting plate and the clamping plate maintain an angle state, preventing the guiding mechanism from contacting the metal plate, and driving the bearing ring to follow the rotation, polishing and removing rust while rotating.

[0006] As a further improvement of the present invention, the trapezoidal block in the sliding tube and the rotating rod are located on the same central axis, and eight rubber blocks are fitted on the inner side of the limiting tube and distributed in an annular manner. The trapezoidal block is embedded in the inner end of the rubber block and cooperates with the outside of the rotating rod for unidirectional movement. A triangular groove is provided on the outer side of the rotating rod and matches with the trapezoidal block, and the rotating rod has the triangular groove only at the position between the two closed plates. When the rotating rod rotates counterclockwise, the triangular groove abuts against the side of the trapezoidal block and drives the limiting tube to rotate and cooperate. Therefore, when the rotating rod is stationary, the clockwise rotation of the limiting tube will be blocked by the triangular groove on the outer side of the rotating rod, and when the protruding handle is manually rotated counterclockwise, the arc groove position after the bearing body is driven to rotate guides the force-bearing structure to stretch outward, pulling the hinge cooperation between the connecting plate and the splint to tend to a planar state, and after the connecting plate and the splint are in the planar state, the lower end of the force-bearing structure abuts against the inner side of the metal plate.

[0007] As a further improvement of the present invention, the filter plate is formed by welding a support rod to the side of the spacer rod, and the lower end of the support rod is embedded with a rubber plate that fits with the upper end of the blocking plate. The spacing between the spacer rods is the same and is spliced ​​inside the connecting plate and the splint. The strip bucket sleeves are evenly arranged on the surface of the blocking plate. The gap between the upper edge of the blocking plate and the spacer rod is smaller than the polishing abrasive in the metal plate. When the connecting plate and the splint tend to be flat, the gravity of the abrasive pulls the rubber plate on the surface of the blocking plate to telescopically cooperate. Therefore, the gap between the upper edge of the blocking plate and the spacer rod will become larger.

[0008] As a further improvement of the present invention, the hinge rod on the force-bearing structure is hinged with the lower end of the connecting plate, the hinge rod is fixed inside the concave rod, and the round rod is only provided with one outside the concave rod for embedded installation.

[0009] As a further improvement of the present invention, the spring is installed at the lower end of the concave rod at an inclination of 10 degrees, and a sponge board is fitted along the shape of the lower surface of the concave rod, and four springs are arranged in the space between the lower end of the sponge board and the upper end of the triangular bar and are wrapped and sealed by the sponge board. Therefore, when the round rod slides outward at the arc groove position, the concave rod has an outward expansion effect. After the connecting plate and the hinge rod move toward a planar state, the triangular bar abuts against the inner side of the metal plate, and the triangular bar produces an inclined pressure on the inner side of the metal plate, which has the effect of making the top angle of the triangular bar press tightly against the inner side of the metal plate.

[0010] It is necessary to explain that the polishing abrasives in the present invention include but are not limited to various common materials such as river sand, steel sand, corundum, diamond, etc. When polishing, the cabinet door is opened to put in the abrasives and mechanical parts. The rotating rod and the cylinder are rotated after the electric control motor is operated. The abrasives roll on the inner wall of the cylinder and the mechanical parts to produce friction. Therefore, the abrasives grind and polish the surface of the mechanical parts to remove rust. When the protruding handle rotates counterclockwise, the connecting plate and the splint form a plane covering the middle half of the hexagon of the metal plate, and the abrasives and mechanical parts on the inner wall of the metal plate are scooped up, and the abrasives are filtered out from the filter plate position, and the mechanical parts stop on the plane formed by the connecting plate and the splint, which is convenient for taking the mechanical parts after polishing. Beneficial Effects

[0011] 1. In the present invention, the protruding handle position in the bearing ring is rotated manually from the outside, which in turn drives the bearing body to rotate, and the arc groove position guides the force-bearing structure to stretch outward, pulling the hinge between the connecting plate and the clamping plate to cooperate toward a planar state, and after the connecting plate and the clamping plate are in the planar state, the lower end of the force-bearing structure abuts against the inner side of the metal plate, and the triangular bar abuts against the inner side of the metal plate under the inclination of the spring, and the trapezoidal block on the inner side of the limit tube under rotation elastically rotates counterclockwise from the hypotenuse and the triangular groove on the outer side of the rotating rod under the elastic force of the rubber block, and the top angle position of the triangular bar is extended and retracted under the rotation to abut against the metal plate and guide it, and then the abrasive leaks out through the filter plate position, leaving the mechanical parts on the plane, which is convenient for opening the cabinet door to take the mechanical parts.

[0012] 2. After the abrasive and mechanical parts are scooped out from the plane formed by the connecting plate and the clamping plate in the present invention, since the mechanical parts are larger than the abrasive, the abrasive squeezes the blocking plate from the gap between the spacer bars under gravity, and the gap between the blocking plate and the spacer bars is expanded under the stretching of the rubber plate, and the gap size is slightly larger than the abrasive and smaller than the mechanical parts. Then, the abrasive will leak out from the gap under the plane rotation, and the rust on the mechanical parts polished by the abrasive is smaller than that of the abrasive. Then, when the abrasive is above the blocking plate, the mixed rust therein is easy to stay in the strip bucket position, and the rust is collected and processed. After the mechanical parts are taken out and all the abrasives leak out from the gap on the edge of the blocking plate, the strip bucket is disassembled to take out the rust to prevent the rust from accumulating in the abrasive and affecting the next polishing and rust removal.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings: As attached Figure 1 To Attachment Fig. 9 As shown: The present invention discloses a mechanical parts polishing and rust removal device for mechanical processing, which structure includes a frame 1, a drum polisher 2, a base 3, a bearing block 4, and a motor 5. The motor 5 is installed at the upper end of the frame 1, and the middle of the drum polisher 2 is connected to the inside of the motor 5 and is rotated together. The drum polisher 2 is limited and movable and rotates at the position of the bearing block 4, and two bearing blocks 4 are welded to the upper end of the base 3, respectively at the left and right sides of the drum polisher 2; The drum polishing machine 2 includes a rotating rod 24 that penetrates the cylinder 22. The rotating rod 24 penetrates and is inserted into the cylinder 22 from the outside to the inside. The guide mechanism 21 is unidirectionally slidably matched with the outer side of the rotating rod 24 inside the cylinder 22. The cabinet door 23 is hingedly installed on the outer side of the cylinder 22. The outer side of the rotating rod 24 is embedded and fixed with the motor 5 at the same horizontal position. The left and right ends of the rotating rod 24 are horizontally limited and rotated at the position of the bearing block 4. The rotating rod 24 is at the central axis position of the regular hexagonal cylinder 22. When the motor 5 drives the operation, the rotating rod 24 and the cylinder 22 are driven by the motor 5 to rotate between the two bearing blocks 4; The cylinder 22 is provided with a metal plate 223 and a closing plate 222. The hexagonal metal plate 223 and two opposite closing plates 222 are welded to each other to form the cylinder 22. Only the closing plate 222 on the side away from the motor 5 is provided with a bearing ring 221 between the two closing plates 222. The outer side of the rotating rod 24 is welded to one of the closing plates 222 and passes through the middle position of the opposite bearing ring 221. One end of the rotating rod 24 is close to the closing plate 222 and is slidably matched with the inner side of the bearing ring 221. When the rotating rod 24 rotates, the metal plate 223 is driven to rotate and match through the welded closing plate 222. The inner and outer layers of the bearing ring 221 are respectively movable with the outer side of the rotating rod 24 and the inner side of the closing plate 222, and the transition matching gap between the bearing ring 221 and the closing plate 222 is small. The guide mechanism 21 includes a clamping plate 46 that is hinged at the outer end of the sliding tube 43, and the sliding tube 43 can only be unidirectionally movable outside the rotating rod 24. The clamping plate 46 and the connecting plate 41 are hinged together through a hinge buckle 42. A filter plate 45 is respectively provided between the clamping plate 46 and the connecting plate 41. The vertical angle between the connecting plate 41 and the clamping plate 46 is 60 degrees to 180 degrees. The lower end of the connecting plate 41 is hinged with the force-bearing structure 44. When the bearing ring 221 rotates counterclockwise, the outer end of the force-bearing structure 44 is located at the shaft The inside of the supporting ring 221 slides in an arc shape near the middle position to guide it to the edge of the closing plate 222, and a plane is formed between the connecting plate 41 and the clamping plate 46 through the hinge buckle 42, and the lower end of the force-bearing structure 44 is in contact with the inner side of the metal plate 223, and when the connecting plate 41 and the clamping plate 46 in a planar state rotate, the mechanical parts and abrasives are driven to their surface, and through the two filter plates 45 on the connecting plate 41 and the clamping plate 46, the mechanical parts are blocked and stay on the surface of the connecting plate 41 and the clamping plate 46, and the smaller abrasives fall and separate from the two filter plates 45 under gravity.

[0024] Among them, the bearing ring 221 is provided with an arc groove 31 and a bearing body 32 on one side inside the closing plate 222, wherein the force-bearing structure 44 is guided to slide at the arc groove 31, and a protruding handle 33 is provided on the outer side of the bearing body 32, which can be manually rotated, and the edge and inner side of the bearing body 32 are provided with recessed grooves, and the recessed grooves are used for rolling and rotating cooperation with the closing plate 222 and the rotating rod 24 after the ball is engaged and limited, and the outer side of the bearing body 32 is transitionally cooperated with the closing plate 222 and the rotating rod 24. Therefore, when the sliding tube 43 is driven by the rotating rod 24 to rotate counterclockwise, the connecting plate 41 is squeezed inward at the bearing body 32, so that the connecting plate 41 and the clamping plate 46 maintain an angle state, prevent the guide mechanism 21 from contacting the metal plate 223, and drive the bearing ring 221 to follow the rotation, and polish and remove rust while rotating.

[0025] The trapezoidal block 433 in the sliding tube 43 and the rotating rod 24 are located on the same central axis, and eight rubber blocks 431 are arranged in an annular manner on the inner side of the limiting tube 432. The trapezoidal block 433 is embedded in the inner end of the rubber block 431 and is engaged with the outer side of the rotating rod 24 for unidirectional movement. A triangular groove is provided on the outer side of the rotating rod 24 to match the trapezoidal block 433, and the rotating rod 24 has a triangular groove only between the two closing plates 222. When the rotating rod 24 rotates counterclockwise, the triangular groove abuts against the rotating rod 24. The side of the trapezoidal block 433 drives the limiting tube 432 to rotate and cooperate. Therefore, when the rotating rod 24 is stationary, the clockwise rotation of the limiting tube 432 will be blocked by the triangular groove on the outside of the rotating rod 24, and when the protruding handle 33 is manually rotated counterclockwise, the arc groove 31 position after the bearing body 32 rotates guides the force-bearing structure 44 to stretch outward, pulling the hinge cooperation between the connecting plate 41 and the splint 46 to tend to a planar state, and after the connecting plate 41 and the splint 46 are in a planar state, the lower end of the force-bearing structure 44 is against the inner side of the metal plate 223.

[0026] Among them, the filter plate 45 is formed by welding the support rod 453 to the side of the spacer rod 452, and the lower end of the support rod 453 is embedded with the rubber plate 451 and fits with the upper end of the blocking plate 455. The spacing between the spacer rods 452 is the same and spliced ​​inside the connecting plate 41 and the clamping plate 46. The strip buckets 454 are evenly arranged on the surface of the blocking plate 455. The gap between the upper edge of the blocking plate 455 and the spacer rod 452 is smaller than the polishing abrasive in the metal plate 223. When the connecting plate 41 and the clamping plate 46 tend to be flat, the gravity of the abrasive pulls the rubber plate 451 on the surface of the blocking plate 455 to telescopically cooperate. Therefore, the gap between the upper edge of the blocking plate 455 and the spacer rod 452 will become larger.

[0027] The hinge rod 445 on the force-bearing structure 44 is hinged with the lower end of the connecting plate 41 , and the hinge rod 445 is fixed inside the concave rod 443 . The round rod 441 is only provided with one outside the concave rod 443 for embedded installation.

[0028] Among them, the spring 446 is installed at the lower end of the concave rod 443 at an inclination of 10 degrees, and a sponge plate 444 is fitted along the shape of the lower surface of the concave rod 443, and four springs 446 are arranged in the space between the lower end of the sponge plate 444 and the upper end of the triangular bar 442 and are wrapped and sealed by the sponge plate 444. Therefore, when the round rod 441 slides outward at the position of the arc groove 31, the concave rod 443 is expanded outward. After the connecting plate 41 and the hinge rod 445 move toward a planar state, the triangular bar 442 abuts against the inner side of the metal plate 223, and the triangular bar 442 produces an inclined pressure on the inner side of the metal plate 223, which has the effect of making the top angle of the triangular bar 442 tightly press the inner side of the metal plate 223.

[0029] It is necessary to explain that the polishing abrasives in the present invention include but are not limited to various common materials such as river sand, steel sand, corundum, diamond, etc. When polishing, the cabinet door is opened to put in the abrasives and mechanical parts. The rotating rod and the cylinder are rotated after the electric control motor is operated. The abrasives roll on the inner wall of the cylinder and the mechanical parts to produce friction. Therefore, the abrasives grind and polish the surface of the mechanical parts to remove rust. When the protruding handle rotates counterclockwise, the connecting plate and the splint form a plane covering the middle half of the hexagon of the metal plate, and the abrasives and mechanical parts on the inner wall of the metal plate are scooped up, and the abrasives are filtered out from the filter plate position, and the mechanical parts stop on the plane formed by the connecting plate and the splint, which is convenient for taking the mechanical parts after polishing. In the present invention, when the motor 5 is not running, the motor 5 rotates in a thread-driven manner, and can fix the rotating rod 24 when it is stationary. Therefore, the protruding handle 33 in the bearing ring 221 is manually rotated from the outside, and then the arc groove 31 position is driven to guide the force-bearing structure 44 to stretch outward, and the hinge between the connecting plate 41 and the clamping plate 46 is pulled to a planar state. After the connecting plate 41 and the clamping plate 46 are in a planar state, the lower end of the force-bearing structure 44 is against the inner side of the metal plate 223, and the triangular bar 442 under the inclination of the spring 446 is against the inner side of the metal plate 223. It is necessary to explain that the plane formed when the triangular bar 442 is against the metal plate 223 is located on the metal plate 223. On the left side of the interior, when rotating counterclockwise, the outer side of the arc position of the arc groove 31 and the bearing body 32 form a barrier to the round rod 441, and at this time, the abrasive and mechanical parts are mixed at the bottom of the metal plate 223. When the rotation continues, the trapezoidal block 433 on the inner side of the lower limit tube 432 elastically rotates counterclockwise from the hypotenuse and the triangular groove on the outer side of the rotating rod 24 under the elastic force of the rubber block 431, and the top angle position of the triangular bar 442 is extended and retracted under the rotation to press against the metal plate 223 and guide it, and then the abrasive and mechanical parts on the inner side of the metal plate 223 are picked up to the lower position of the right cabinet door 23, and then the abrasive leaks out through the position of the filter plate 45, leaving the mechanical parts on the plane, which is convenient for opening the cabinet door 23 to take out the mechanical parts.

[0030] After the abrasive and mechanical parts are scooped out from the plane formed by the connecting plate 41 and the clamping plate 46 in the present invention, since the mechanical parts are larger than the abrasive, the abrasive squeezes the blocking plate 455 from the gap between the spacer bars 452 under gravity, and the gap between the blocking plate 455 and the spacer bars 452 is expanded under the stretching of the rubber plate 451, and the gap size is slightly larger than the abrasive and smaller than the mechanical parts. Then, the abrasive will leak out from the gap under the plane rotation, and the rust on the mechanical parts polished by the abrasive is smaller than the abrasive. Then, when the abrasive is above the blocking plate 455, the mixed rust therein is easy to stay at the position of the strip bucket 454, and the rust is collected and processed. After the mechanical parts are taken out and all the abrasives leak out from the gap on the upper edge of the blocking plate 455, the strip bucket 454 is disassembled to take out the rust to prevent the rust from accumulating in the abrasive and affecting the next polishing and rust removal. Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
