Description

Technical Field

[0001] This invention belongs to the field of mechanical parts processing technology, and specifically relates to a shearing processing device for processing mechanical parts. Background Technology

[0002] Mechanical parts are the basic components that make up machinery. They are inseparable individual parts that make up machinery and machines. During the production and processing of mechanical parts, they often need to be cut so that they can be further processed later.

[0003] A search revealed that Chinese Patent Publication No. CN219944809U, published on November 3, 2023, discloses a cutting device for machining mechanical parts. The device includes a base, an adjustment structure at one end of the base, a rotating seat fixedly connected to the top of the adjustment structure, a cutting disc rotatably connected to the top of the rotating seat, a drive motor fixedly connected to one end of the cutting disc, a lever fixedly connected to the other side of the cutting disc, and a cutting wheel rotatably connected to the inner wall of the cutting disc. This invention, through the adjustment structure, allows the rotating seat to rotate the scale adjustment disc to a suitable angle. Then, the spring force of a return spring causes the sliding seat to slide, moving the positioning block into a suitable positioning hole, thus achieving limited positioning and fixing after the positioning hole rotates. This allows the cutting angle of the cutting wheel to be changed, avoiding the limitation of traditional cutting wheels that can only move vertically up and down for cutting, and improving the applicability for cutting mechanical parts.

[0004] However, the device still has the following drawbacks:

[0005] After prolonged cutting, circular saw blades are prone to deformation or chipping. Continued use affects cutting quality, and maintenance requires disassembling the blade, which is inconvenient. As a result, the device lacks effective maintenance for the circular saw blade.

[0015] Furthermore, each set of lifting blocks is provided with a set of second return springs at its top and bottom; the other end of each set of second return springs is connected to the inner wall of the corresponding set of lifting blocks or lifting channels; each set of lifting blocks is provided with a set of first electric push rods on the side wall away from the contact block; the output end of each set of first electric push rods is hinged to the corresponding set of contact blocks.

[0019] The beneficial effects of this invention are:

[0020] 1. By controlling two sets of translation plates to rapidly impact the circular saw blade, and four sets of electric slides to drive four sets of processing blocks to move from the axial area of ​​the circular saw blade to both sides, combined with the fixed 45° rotation of the circular saw blade, the four sets of processing blocks can impact the circular saw blade to simulate the cross-shaped hammering repair method. At the same time, by controlling the horizontal rotation of the processing blocks, the grinding surface of the processing blocks can be made to fit the circular saw blade at different tilt angles. Combined with the high-speed rotation of the circular saw blade, the blade of the circular saw blade can be ground evenly, thereby improving the maintenance effect of the shearing processing device on the circular saw blade.

[0021] 2. By controlling the clamping structure, the two sets of second mounting frames are moved toward the mechanical parts, so that one or more sets of abutting blocks abut against the outer wall of the mechanical parts. When the fixed contact surface is irregular, the corresponding distance sensor can detect the distance between the abutting block and the part and control the output end of the corresponding first electric push rod to extend, so that the corresponding abutting block can abut against the surface of the mechanical parts. This not only increases the fixed force-bearing area of ​​the mechanical parts and improves the stability of the mechanical parts, but also avoids the problem of deformation of the contact part due to the small fixed contact area.

[0022] 3. By controlling the second electric guide rail to move the auxiliary box to the shearing part of the mechanical part, four sets of stabilizing plates extend from the corresponding storage slots, so that the four sets of elastic plates can wrap around the outer wall of the mechanical part to reinforce the shearing part. This prevents the mechanical part from deforming under the combined action of high pressure concentration and shearing tearing when the circular saw structure completely cuts the mechanical part. At the same time, during the shearing process, the two sets of lifting baffles can automatically adjust their height according to the height of the circular saw structure to block the splashing of metal chips, thereby improving both the shearing quality and the protection effect.

[0023] 4. By controlling the robotic arm structure to drive the circular saw structure into the collection trough, several sets of second electric push rods are then controlled to move two sets of cleaning plates toward the circular saw blade, so that two sets of guide rollers and four sets of cleaning rollers abut against the two side walls of the circular saw blade. Then, the two sets of guide rollers are controlled to rotate, driving the circular saw blade to rotate, so that the four sets of cleaning rollers can clean the surface of the circular saw blade. At the same time, several sets of air jets can spray hot air through the corresponding existing equipment to dry the surface of the circular saw blade, thereby improving the service life of the shearing processing device.

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.

[0037] When performing shearing work on mechanical parts, the mechanical parts are first fixed on two sets of part fixing mechanisms 10. Then, according to the shearing requirements, the first electric guide rail 3 is controlled to move the circular saw structure 6 to the corresponding position through the movable mounting base 4 and the robotic arm structure 5. Then, the robotic arm structure 5 is controlled to move the circular saw structure 6 to shear the corresponding area of ​​the mechanical parts. At the same time, the second electric guide rail 9 can drive the auxiliary shearing mechanism 11 to move to the shearing area to perform auxiliary shearing work.

[0038] For example, such as Figure 2 , Figure 3 and Figure 4As shown, the circular saw maintenance mechanism 7 includes a first mounting frame 701; the first mounting frame 701 is mounted on the output end opening of the circular saw structure 6; two sets of translation plates 702 are symmetrically arranged on the inner walls of both sides of the first mounting frame 701; several sets of hydraulic impact structures 703 are symmetrically arranged on the outer walls of both sides of the first mounting frame 701; the output ends of several sets of hydraulic impact structures 703 on the same side are all connected to a corresponding set of translation plates 702; two sets of guide plates 704 are symmetrically arranged on the top of the two sets of translation plates 702; two sets of limiting slots 705 are opened on each set of guide plates 704; a set of processing blocks 706 is arranged in each set of limiting slots 705; each set of processing blocks 706 is square-shaped, and the two side walls in the horizontal direction are set as arc surfaces; each set of processing blocks 706 is far away from the corresponding set of guide plates 704. One side wall of each of the following is set as a polishing surface; the top of each group of translation plates 702 is provided with two sets of electric slides 707; the two sets of electric slides 707 are symmetrically arranged on both sides of the two sets of guide plates 704; a set of mounting blocks 711 are drivenly connected to the output end of each set of electric slides 707; the end of each set of mounting blocks 711 away from the corresponding set of electric slides 707 is drivenly connected to the corresponding set of processing blocks 706; the top of each group of translation plates 702 is provided with several sets of sliding grooves 708; a set of sliders 709 are slidably connected in each set of sliding grooves 708; a set of first return springs 710 are provided on one side wall of each set of sliders 709; the other end of each set of first return springs 710 is connected to one side wall of the corresponding set of sliding grooves 708; the top of each set of sliders 709 is connected to the bottom of the corresponding set of electric slides 707.

[0039] When the circular saw blade of the circular saw structure 6 deforms or becomes chipped, several sets of hydraulic impact structures 703 can be controlled to drive two sets of translation plates 702 to rapidly impact the circular saw blade. Furthermore, by controlling four sets of electric slides 707, four sets of processing blocks 706 move from the axial region of the circular saw blade to both sides. Combined with the fixed 45° rotation of the circular saw blade, the four sets of processing blocks 706 can impact the circular saw blade, simulating a cross-shaped hammering repair method. Simultaneously, by controlling the horizontal rotation of the processing blocks 706, since the two side walls of the processing blocks 706 are curved, and the four sets of electric slides 707 can elastically move in the horizontal direction through the sliding grooves 708, sliders 709, and the first return spring 710, the grinding surface of the processing blocks 706 can fit against the circular saw blade at different tilt angles. Combined with the high-speed rotation of the circular saw blade, the blade can be ground evenly, thereby improving the maintenance effect of the shearing processing device on the circular saw blade.

[0040] For example, such as Figure 5 and Figure 6As shown, the part fixing mechanism 10 includes a clamping structure 1001; the clamping structure 1001 is connected to the output ends of two sets of second electric guide rails 9; two sets of second mounting frames 1002 are symmetrically connected to the output ends of the clamping structure 1001; several sets of abutment blocks 1003 are respectively provided on the opposite side wall of the two sets of second mounting frames 1002; several sets of abutment blocks 1003 on the same side are sequentially hinged together; a set of mounting grooves 1004 are opened on the side wall of each set of abutment blocks 1003 away from the corresponding set of second mounting frames 1002; a set of distance sensors 1005 are provided in each set of mounting grooves 1004. Each set of second mounting frames 1002 is provided with a set of lifting channels 1006; each set of lifting channels 1006 is slidably connected with several sets of lifting blocks 1007 in the vertical direction; each set of lifting blocks 1007 is provided with a set of second return springs 1008 at the top and bottom; the other end of each set of second return springs 1008 is connected to the inner wall of the corresponding set of lifting blocks 1007 or lifting channels 1006; each set of lifting blocks 1007 is provided with a set of first electric push rods 1009 on the side wall away from the abutment block 1003; the output end of each set of first electric push rods 1009 is hinged to the corresponding set of abutment blocks 1003.

[0041] When fixing mechanical parts, the clamping structure 1001 is controlled to move two sets of second mounting frames 1002 toward the mechanical parts, so that one or more sets of abutment blocks 1003 abut against the outer wall of the mechanical parts. When the fixing contact surface is irregular, the corresponding distance sensor 1005 can detect the distance between the abutment block 1003 and the part, and control the output end of the corresponding first electric push rod 1009 to extend, so that the corresponding abutment block 1003 can abut against the surface of the mechanical parts. This not only increases the fixing force area of ​​the mechanical parts and improves the stability of the mechanical parts, but also avoids the problem of deformation of the contact part due to the small fixing contact area.

[0042] For example, such as Figure 7 and Figure 8As shown, the auxiliary shearing mechanism 11 includes an auxiliary housing 1101; a collection groove 1102 is provided on the top of the auxiliary housing 1101; four sets of storage grooves 1103 are symmetrically provided on the two sides of the top of the auxiliary housing 1101; a set of stabilizing plates 1104 are provided in each set of storage grooves 1103; the cross-section of each set of stabilizing plates 1104 is fan-shaped, and an elastic sheet 1105 is provided on the concave surface; two sets of lifting baffles 1106 are symmetrically and movably inserted through the top of the auxiliary housing 1101 perpendicular to the two sides of the collection groove 1102; two sets of telescopic grooves 1109 are symmetrically provided on the inner walls of both sides of the collection groove 1102; a set of cleaning plates 1110 is provided in each set of telescopic grooves 1109; the auxiliary housing 1101 Several sets of second electric push rods 1107 are symmetrically arranged on both sides of the container; several sets of second electric push rods 1107 on the same side are all connected to a corresponding set of cleaning plates 1110; a set of collection boxes 1108 are movably inserted through one side of the inner wall of the collection tank 1102; the cross-section of each set of cleaning plates 1110 is fan-shaped; a set of guide rollers 1111 are provided at the bottom of the side wall of each set of cleaning plates 1110 away from the corresponding second electric push rod 1107; two sets of cleaning rollers 1112 are symmetrically arranged on the side wall of each set of cleaning plates 1110 away from the corresponding second electric push rod 1107; several sets of air jet holes 1113 are evenly distributed on the side wall of each set of cleaning plates 1110 away from the corresponding second electric push rod 1107.

[0043] When shearing mechanical parts, the auxiliary box 1101 is moved to the shearing position of the mechanical parts by controlling the second electric guide rail 9. Then, four sets of stabilizing plates 1104 are extended from the corresponding storage slots 1103, so that four sets of elastic plates 1105 can wrap around the outer wall of the mechanical parts to reinforce the shearing position. This prevents the mechanical parts from deforming under the combined action of high pressure concentration and shearing tearing when the circular saw structure 6 completely cuts the mechanical parts. At the same time, during the shearing process, the two sets of lifting baffles 1106 can automatically adjust their height according to the height of the circular saw structure 6 to block the splashing of metal chips, which improves the shearing quality and the protection effect. After the shearing work is completed, the controllable robotic arm structure 5 drives the circular saw structure 6 to extend into the collection trough 1102. Then, several sets of second electric push rods 1107 are controlled to drive two sets of cleaning plates 1110 to move toward the circular saw blade, so that two sets of guide rollers 1111 and four sets of cleaning rollers 1112 abut against the two side walls of the circular saw blade. Then, the two sets of guide rollers 1111 are controlled to rotate, driving the circular saw blade to rotate, so that the four sets of cleaning rollers 1112 can clean the surface of the circular saw blade. At the same time, several sets of air jet holes 1113 can spray hot air through the corresponding existing equipment to dry the surface of the circular saw blade, thereby improving the service life of the shearing processing device.

[0044] By controlling several sets of hydraulic impact structures 703 to drive two sets of translation plates 702 to rapidly impact the circular saw blade, and four sets of electric slides 707 to drive four sets of processing blocks 706 to move from the axial area of ​​the circular saw blade to both sides, in conjunction with the fixed 45° rotation of the circular saw blade, the four sets of processing blocks 706 can impact the circular saw blade to simulate the cross-shaped hammering repair method. At the same time, by controlling the rotation of the processing blocks 706 in the horizontal direction, the grinding surface of the processing blocks 706 can be made to fit the circular saw blade at different tilt angles. In addition, in conjunction with the high-speed rotation of the circular saw blade, the blade of the circular saw blade can be ground evenly, thereby improving the maintenance effect of the shearing processing device on the circular saw blade.

[0045] By controlling the clamping structure 1001 to move the two sets of second mounting frames 1002 toward the mechanical parts, one or more sets of abutting blocks 1003 abut against the outer wall of the mechanical parts. When the fixed contact surface is irregular, the corresponding distance sensor 1005 can detect the distance between the abutting block 1003 and the part, and control the output end of the corresponding first electric push rod 1009 to extend, so that the corresponding abutting block 1003 can abut against the surface of the mechanical parts. This not only increases the fixed force-bearing area of ​​the mechanical parts and improves the stability of the mechanical parts, but also avoids the problem of deformation of the contact part due to the small fixed contact area.

[0046] By controlling the second electric guide rail 9 to move the auxiliary box 1101 to the shearing part of the mechanical part, and then controlling the four sets of stabilizing plates 1104 to extend from the corresponding storage slots 1103, the four sets of elastic plates 1105 can wrap around the outer wall of the mechanical part to reinforce the shearing part. This prevents the mechanical part from deforming under the combined action of high pressure concentration and shearing tearing when the circular saw structure 6 completely cuts the mechanical part. At the same time, during the shearing process, the two sets of lifting baffles 1106 can automatically adjust their height according to the height of the circular saw structure 6 to block the splashing of metal chips, thereby improving the shearing quality and the protection effect.

[0047] By controlling the robotic arm structure 5 to drive the circular saw structure 6 into the collection trough 1102, several sets of second electric push rods 1107 are controlled to drive two sets of cleaning plates 1110 towards the circular saw blade, so that two sets of guide rollers 1111 and four sets of cleaning rollers 1112 abut against the two side walls of the circular saw blade. Then, the two sets of guide rollers 1111 are controlled to rotate, driving the circular saw blade to rotate, so that the four sets of cleaning rollers 1112 can clean the surface of the circular saw blade. At the same time, several sets of air jet holes 1113 can spray hot air through the corresponding existing equipment to dry the surface of the circular saw blade, thereby improving the service life of the shearing processing device.
