Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, and in particular relates to a large-scale parts conveying and turning mechanism. Background Art

[0002] During the conveying and flipping process of large parts, the existing flat clamp flipping mechanism has several technical problems, which limits its application effect in industrial production.

[0003] First, when the flat clamp is used to clamp a large part that is concave inward or has an uneven surface, the effective contact area between the flat clamp and the large part is smaller than the projected area between the large part and the flat clamp, resulting in excessive local contact pressure, which can easily cause local extrusion deformation of the large part, affecting the quality and precision of the part; secondly, when the rigid flat clamp is in hard contact with the rigid large part, it will not only cause surface damage to the large part, but may also damage the flat clamp itself, increasing maintenance costs and the risk of production interruption; in addition, in the existing flipping mechanism, the friction stroke between the brake disc device and the gear sleeve seat is relatively short, and under high load and high impact conditions, the brake disc has poor stability and a short service life, which not only affects the smoothness and safety of the flipping process, but also increases the maintenance frequency and maintenance cost of the equipment.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention first reversely activates the first telescopic rod above to move the valve upward and separate from the discharge hole, so that the rubber ball in the inner cavity of the installation shell falls into the middle of the upper and lower feeding mechanisms, the front and rear side pressure mechanisms and the left and right valve mechanisms through the discharge hole. Then, the second telescopic rod is activated in a positive and negative direction alternately, and the rubber ball that falls into the gap between the upper and lower feeding mechanisms, the two side pressure mechanisms, the left and right valve mechanisms and the large parts transportation is filled with the grooves on the side of the large parts themselves and the gaps between the side of the large parts and the upper and lower feeding mechanisms, the front and rear side pressure mechanisms and the left and right valve mechanisms under the alternating vibration of the front and rear side pressure mechanisms, so that the large parts with an inward concave shape and the rubber ball together form a regular rectangle. Then, the first telescopic rod is activated in a positive direction, and the upper and lower feeding mechanisms are pressed against the rubber ball. The large parts and the rubber ball are clamped up and down, and the side pressure mechanism is started at the same time. The two side pressure mechanisms clamp the large parts and the rubber ball front and back, and then the driving seat is started. The output end of the driving seat drives the gear to rotate, and the gear drives the gear sleeve seat to rotate. The driving seat drives the large parts and the rubber ball clamped in the middle to flip clockwise through the feeding mechanism and the side pressure mechanism, thereby realizing the filling of the inward recessed parts of the large parts by the rubber balls, overcoming the flipping of the existing flat splint. When clamping the inwardly recessed large parts, the effective contact area between the flat splint and the large parts is smaller than the projection area between the large parts and the flat splint, causing local extrusion and deformation of the large parts. At the same time, it avoids the problem of damage to the flat splint and the large parts when the rigid flat splint is in hard contact with the rigid large parts.

[0013] 2. The present invention sets a deceleration mechanism and a clamping mechanism to press the large parts to the speed of rotation of the gear sleeve seat, and adjusts the friction resistance between the friction block and the fixed plate and the sliding plate, so that when the gear sleeve seat rotates faster, the friction resistance between the friction block and the fixed plate and the sliding plate is greater, the speed at which the friction block moves toward the gear sleeve seat is slower, and the force with which the friction block pulls the gear sleeve seat is greater, thereby making the gear sleeve seat rotation resistance greater, and then the gear sleeve seat drives the large parts to turn stably through the feeding mechanism and the side pressure mechanism, and converts the gravitational potential energy of the rotation into heat energy for stable release. In addition, the clamping mechanism and the movable pulley can be provided to control the friction load between the friction block and the fixed plate and the sliding plate and increase the friction stroke, thereby increasing the service life of the fixed plate, the sliding plate and the friction block, thereby overcoming the problems of short friction stroke, large load and large impact between the existing brake disc device installed on the side of the gear sleeve seat and the gear sleeve seat, which cause the brake disc to be unstable and have a short service life.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figures 1 to 5As shown, an embodiment of the present invention provides a large-scale parts conveying and flipping mechanism, including a base 1, a curved groove 101 is provided on the left side of the upper surface of the base 1, and a sliding groove 102 is symmetrically provided in the middle of the right side of the upper surface of the base 1. The front and rear sides of the curved groove 101 are symmetrically slidably sleeved with a gear sleeve seat 2, and the middle part of the outer curved surface of the gear sleeve seat 2 is provided with an annular groove, so as to facilitate the subsequent fixation of the wire end of the cable receiving disk 610, while preventing the wire from being entangled in the rotating gear sleeve seat 2 and contacting the sliding groove 102, causing the gear sleeve seat 2 to rotate and become stuck. The outer curved surface of the gear sleeve seat 2 is provided with a tooth groove, so as to facilitate the subsequent engagement with the gear 301. The right side of the upper surface of the base 1 is symmetrically fixed with a drive seat. 3. A gear 301 is fixedly installed on the output end of the drive seat 3. The gear 301 is meshed with the gear sleeve seat 2. Feed mechanisms 4 are symmetrically provided on the upper and lower sides of the inner curved surfaces of the two gear sleeve seats 2. The upper feeding mechanism 4 includes a mounting shell 401. The mounting shell 401 is arranged on the upper part of the inner curved surface of the gear sleeve seat 2. A plurality of discharge holes 402 are equidistantly provided at the bottom of the inner cavity of the mounting shell 401. Baffles 403 are symmetrically fixedly installed on the upper part of the front and rear sides of the inner cavity of the mounting shell 401. First telescopic rods 404 are fixedly installed on the top of the inner curved surfaces of the two gear sleeve seats 2. Connecting plates 405 are fixedly installed on the telescopic ends of the two first telescopic rods 404. The connecting plate 405 is slidably sleeved in the middle of the two baffles 403. Among them, a plurality of connecting rods 406 are fixedly installed at equal intervals on the bottom surface of the connecting plate 405, and a plurality of valves 407 are fixedly installed at equal intervals on the bottom of the plurality of connecting rods 406. The valves 407 are slidably sleeved with the discharge holes 402, and the inner cavity of the mounting shell 401 is filled with rubber balls. The use of rubber balls can prevent the mounting shell 401, the electromagnetic plate 503, the sleeve plate 505 and the magnetic door 803 from contacting the diameter of the large parts, causing damage and deformation of the surface of the large parts. The diameter of the rubber ball is smaller than the minimum groove size on the surface of the large parts, so that the rubber ball can fill the minimum groove on the surface of the large parts, making the surface formed by the large parts and the rubber ball smoother, thereby increasing the indirect contact area between the subsequent large parts and the mounting shell 401, the electromagnetic plate 503, the sleeve plate 505 and the magnetic door 803. The middle part of the rubber ball is wrapped with metal particles, so that after the large parts are flipped, the electromagnetic plate 503 is started and the electromagnetic plate 503 generates magnetic force The rubber ball is attached to the surface of the electromagnetic plate 503 and separated from the large parts, which makes it easy to recover the rubber ball. The width of the discharge hole 402 is greater than the diameter of three rubber balls, so as to prevent the rubber ball from being stuck in the middle of the discharge hole 402, causing the speed of the rubber ball falling to fill the cavity formed by the feeding mechanism 4, the side pressure mechanism 5 and the valve mechanism 8 to slow down. The front and rear sides of the upper surface of the connecting rod 406 are symmetrically fixed with elastic sleeves 408, and the bottom of the inner cavity of the elastic sleeve 408 is fixedly installed with a first elastic member 409. The top of the first elastic member 409 is fixedly installed with an elastic rod 410, which is slidably sleeved in the middle of the elastic sleeve 408. The top of the elastic rod 410 is fixedly connected to the baffle 403 on the same side. The front and rear sides of the inner curved surfaces of the two gear sleeve seats 2 are symmetrically provided with side pressure mechanisms 5, the rear side of the upper surface of the base 1 is provided with a deceleration mechanism 6, the middle part of the rear side of the upper surface of the base 1 is provided with a clamping mechanism 7, and the left and right sides of the feeding mechanism 4 are symmetrically provided with valve mechanisms 8.

[0018] like Figure 2 and Figure 4As shown, the front side pressure mechanism 5 includes a second telescopic rod 501, which is fixedly mounted on the front side of the inner curved surface of the gear sleeve seat 2, and a cushion block 502 is fixedly mounted on the telescopic end of the second telescopic rod 501. An electromagnetic plate 503 is fixedly mounted on the rear side of the cushion block 502. Elastic blocks 504 are fixedly mounted on the upper and lower sides of the electromagnetic plate 503. A sleeve plate 505 is fixedly mounted on the side of the two elastic blocks 504 away from the electromagnetic plate 503. The sleeve plate 505 is slidably sleeved with the electromagnetic plate 503, and the sleeve plate 505 is fixedly connected to the adjacent mounting shell 401, thereby realizing Now when the mounting shell 401 moves toward the pad 502, the mounting shell 401 pushes the sleeve plate 505 to squeeze the elastic block 504 and shrink it toward the middle of the electromagnetic plate 503. The mounting shell 401 clamps the large parts. The two sleeve plates 505 are fixedly installed with sealing plates 506 in front. The sealing plates 506 are in sliding contact with the adjacent mounting shells 401. By setting the sealing plates 506, the rubber balls dropped from the upper mounting shell 401 are prevented from flowing into the outside of the two electromagnetic plates 503, and the discharge holes 402 located on the outside of the two electromagnetic plates 503 are sealed.

[0019] like Figure 1 and Figure 2As shown, the speed reduction mechanism 6 includes two fixed plates 601, and the two fixed plates 601 are symmetrically fixedly installed on the rear side of the upper surface of the base 1. The middle part of the two sliding grooves 102 is slidably sleeved with a sliding plate 602. The two sliding plates 602 are located on the inner side of the two fixed plates 601. The bottom of the fixed plate 601 and the sliding plate 602 are slidably sleeved with a friction block 603. The contact surface of the friction block 603 with the fixed plate 601 and the sliding plate 602 is a rough surface, thereby improving the friction block 603 with the fixed plate 601 and the sliding plate 602, improve the deceleration efficiency of the reduction mechanism 6 on the gear sleeve seat 2, the fixed plate 601, the sliding plate 602 and the friction block 603 are made of wear-resistant materials, thereby slowing down the wear of the fixed plate 601, the sliding plate 602 and the friction block 603 and improving the service life of the fixed plate 601, the sliding plate 602 and the friction block 603. In addition, when in use, cold water can be sprayed on the surface of the fixed plate 601, the sliding plate 602 and the friction block 603 to reduce the wear of the fixed plate 601, the sliding plate 602 and the friction block 60 3. The heat generated by friction is used to improve its service life. A mounting seat 604 is fixedly installed on the rear side of the fixed plate 601. A second elastic member 605 is fixedly installed in front of each mounting seat 604. The front end of the second elastic member 605 is fixedly connected to the adjacent friction block 603. A movable pulley 606 is slidably sleeved on the upper part of the fixed plate 601 and the sliding plate 602. A first steel cable 607 is symmetrically fixedly installed on the upper surface of the mounting seat 604. The other end of the first steel cable 607 passes over the curved surface of the movable pulley 606 and is connected to the front of the friction block 603. The ends are fixedly connected, a ring 608 is slidably sleeved on the middle part of the movable pulley 606, a connecting rope 609 is fixedly installed on the curved surface of the ring 608, and a cable-collecting disc 610 is fixedly installed on the end of the connecting rope 609 close to the gear sleeve seat 2. The rope head of the cable-collecting disc 610 is fixedly installed in the middle of the outer curved surface of the gear sleeve seat 2. The first steel cable 607, the connecting rope 609 and the cable-collecting disc 610 are all steel cables, so as to avoid the first steel cable 607, the connecting rope 609 and the cable-collecting disc 610 from breaking when the gear sleeve seat 2 pulls the deceleration mechanism 6.

[0020] like Figure 1 、 Figure 2 and Figure 5As shown, the pressing mechanism 7 includes a water shell 701, which is fixedly mounted on the middle part of the upper surface of the base 1. The upper part of the water shell 701 is fixedly sleeved with an output pipe, and the left and right sides of the water shell 701 are symmetrically fixedly sleeved with water pumps 702. The surface of the rotating shaft of the water pump 702 is provided with a rubber layer, thereby increasing the friction resistance between the rotating shaft of the water pump 702 and the cable of the cable collecting disc 610, thereby preventing the cable collecting disc 610 from moving relative to the rotating shaft of the water pump 702 when the cable of the cable collecting disc 610 moves along the rotating shaft of the water pump 702. The water pump 702 cannot work normally because the water shell 701 slides, and a telescopic sleeve 703 is fixedly sleeved in the middle of the rear side of the water shell 701. A telescopic rod 704 is slidably sleeved in the middle of the telescopic sleeve 703. A first movable seat 705 is fixedly installed on the end of the telescopic rod 704 away from the water shell 701. Two curved rods 706 are movably sleeved in the middle of the first movable seat 705. A second movable seat 707 is fixedly installed on the end of the two curved rods 706 away from the water shell 701. The second movable seat 707 is fixedly connected to the sliding plate 602 on the same side.

[0021] like Figure 1 As shown, the valve mechanism 8 includes an electromagnetic seat 801, which is fixedly mounted on the left side of the bottom mounting shell 401. Guide rods 802 are symmetrically fixedly mounted on the upper surface of the electromagnetic seat 801, and a magnetic door 803 is slidably sleeved in the middle of the two guide rods 802, so that when the electromagnetic seat 801 is energized in the forward direction, the electromagnetic seat 801 generates a magnetic field in the same direction as the magnetic door 803 to push the magnetic door 803 to move upward. When the electromagnetic seat 801 is energized in the reverse direction, the electromagnetic seat 801 generates a magnetic field in the opposite direction to the magnetic door 803 to attract the magnetic door 803 to move downward, thereby opening or closing the two sides of the mounting shell 401, which is convenient for the installation of large parts.

[0022] Working principle: When the present invention is used, the electromagnetic base 801 is first started in the forward direction, and the electromagnetic base 801 generates a magnetic field in the same direction as the magnetic door 803, which pushes the magnetic door 803 to move upward. Then, after the large parts are transported to the middle of the upper surface of the bottom mounting shell 401, the electromagnetic base 801 is started in the reverse direction, and the electromagnetic base 801 generates a magnetic field in the opposite direction to the magnetic door 803, which attracts the magnetic door 803 to move downward, so that the openings on both sides of the mounting shell 401 are closed. Then, the two first telescopic rods 404 above are started in the reverse direction, and the telescopic ends of the first telescopic rods 404 move upward. The telescopic end of the telescopic rod 404 drives the connecting plate 405 to move upward, the connecting plate 405 drives the connecting rod 406 to move upward, and the connecting rod 406 drives the elastic sleeve 408 to move upward. At this time, since the elastic force formed by the multiple first elastic members 409 is greater than the weight of the mounting shell 401 and the inner cavity rubber ball, the elastic sleeve 408 pushes the elastic rod 410 to move upward through the first elastic member 409, and the elastic rod 410 drives the baffle 403 to move upward, and the baffle 403 drives the mounting shell 401 to move upward until the mounting shell 401 contacts the inner curved surface of the gear sleeve seat 2. At this time, the connecting rod 406 that continues to move upward pushes the elastic sleeve 408 to compress the first elastic member 409 to contract, and the connecting rod 406 drives the valve 407 to move upward, and the valve 407 is separated from the discharge hole 402. The rubber ball in the inner cavity of the mounting shell 401 falls into the middle of the upper and lower mounting shells 401, the front and rear side pressure mechanisms 5 and the left and right valve mechanisms 8 through the discharge hole 402. At the same time, the second telescopic rod 501 is activated alternately forward and backward. The telescopic end of the second telescopic rod 501 pushes the cushion block 502 to move alternately forward and backward, and the sleeve plate 505 drives the electromagnetic plate 50 3 moves back and forth alternately, and the electromagnetic plate 503 drives the sleeve plate 505 to move back and forth alternately. At this time, the rubber ball that falls into the middle between the upper and lower feeding mechanisms 4, the front and rear side pressure mechanisms 5, the left and right valve mechanisms 8 and the large part transportation is vibrated back and forth alternately by the elastic block 504 and the sleeve plate 505, filling the groove of the large part itself and the gap between the large part and the upper and lower feeding mechanisms 4, the front and rear side pressure mechanisms 5, and the left and right valve mechanisms 8, so that the large part with an inward concave shape and the rubber ball together form a regular rectangle; Then the first telescopic rod 404 is started forward, and the telescopic end of the first telescopic rod 404 moves downward. At this time, the first elastic member 409 is reset first, and the first elastic member 409 pushes the elastic rod 410 to move upward. The elastic rod 410 pushes the baffle 403 to move upward, and the baffle 403 drives the mounting shell 401 to move upward until the discharge hole 402 contacts the valve 407. At this time, the rubber ball stops falling under the discharge hole 402, and the first telescopic rod 404 whose telescopic end continues to move downward pushes the connecting plate 405 to move downward, and the connecting plate 405 pushes the connecting rod 406 to move downward, and the connecting rod 406 pushes the mounting shell 401 to move downward, and the upper and lower mounting shells 401 clamp the large parts and the rubber ball up and down, and at the same time, the front and rear side pressure mechanisms 5 are started, and the two side pressure mechanisms 5 clamp the large parts and the rubber ball. The rubber ball is clamped front and back, and then the drive seat 3 is started. The output end of the drive seat 3 drives the gear 301 to rotate, and the gear 301 drives the gear sleeve seat 2 to rotate. The gear sleeve seat 2 drives the large parts clamped in the middle and the rubber ball to flip clockwise through the feeding mechanism 4 and the side pressure mechanism 5, so that the inward recessed parts of the large parts are filled by the rubber ball, so that the rubber ball and the irregularly shaped large parts form a regular rectangle, overcoming the flipping device of the existing plane splint. When clamping the inwardly recessed large parts, the effective contact surface between the plane splint and the large parts is smaller than the contact projection surface between the large parts and the plane splint, causing the problem of local extrusion and deformation of the large parts. At the same time, it avoids the problem of damage to the plane splint and the large parts when the rigid plane splint is in hard contact with the rigid large parts.

[0023] When the driving seat 3 drives the gear sleeve seat 2 to rotate clockwise through the gear 301, the gear sleeve seat 2 pulls the wire of the cable collection disc 610 to extend. When the gear sleeve seat 2 drives the wire of the cable collection disc 610 and the fixed end of the gear sleeve seat 2 to rotate to the top of the gear sleeve seat 2, the wire of the cable collection disc 610 is extended to the maximum. At this time, when the weight of the top of the overturned large part is greater than the gravity at the bottom, the large part will force the gear sleeve seat 2 to rotate clockwise with great kinetic energy under its huge gravity. At this time, the gear sleeve seat 2 pulls the movable pulley 606 toward the gear sleeve seat 2 through the cable collection disc 610, the connecting cable 609 and the ring 608. The movable pulley 606 pulls the friction block 603 toward the gear sleeve seat 2 through the first steel cable 607. At this time, due to the force-saving principle of the movable pulley 606, the moving distance of the friction block 603 is increased, thereby reducing the speed and kinetic energy of the friction block 603 when moving toward the gear sleeve seat 2 per unit time. At the same time, the thread of the fixed plate 601 drives the water pump 702 to rotate, and the input end of the water pump 702 sucks water from the external water pool and outputs it to the external pool through the output pipe on the top of the water shell 701. At this time, since the size of the output pipe remains unchanged, when the speed of the gear sleeve seat 2 is faster, the thread of the fixed plate 601 drives the water pump 702 to rotate faster, the water pressure in the inner cavity of the water shell 701 is higher, and the water pressure in the inner cavity of the water shell 701 pushes the telescopic rod 704 in the direction away from the gear sleeve seat 2. The output pressure is greater, and the telescopic rod 704 pushes the inner sliding plate 602 outward through the first movable seat 705, the curved rod 706 and the second movable seat 707 to squeeze and frictionally contact the sliding plate 602 in the middle of its fixed plate 601, reducing The speed of the friction block 603 moving toward the gear sleeve seat 2 reduces the rotation speed of the gear sleeve seat 2, thereby adjusting the friction resistance between the friction block 603 and the fixed plate 601 and the sliding plate 602 according to the speed at which the large part presses the gear sleeve seat 2 to rotate, so that when the gear sleeve seat 2 rotates faster, the friction resistance between the friction block 603 and the fixed plate 601 and the sliding plate 602 increases, and the slower the speed of the friction block 603 moving toward the gear sleeve seat 2, the greater the force with which the friction block 603 pulls the gear sleeve seat 2, thereby increasing the rotation resistance of the gear sleeve seat 2, and then the gear sleeve seat 2 drives the large part to turn stably through the feeding mechanism 4 and the side pressure mechanism 5, and converts the gravitational potential energy of the rotation into heat energy for stable release; In addition, in actual use, the friction load between the friction block 603 and the fixed plate 601 and the sliding plate 602 can be further reduced and the friction stroke can be increased by providing multiple movable pulleys 606 and a reduction mechanism 6, thereby increasing the service life of the fixed plate 601, the sliding plate 602 and the friction block 603, thereby overcoming the problem that the existing brake disc device installed on the side of the gear sleeve seat 2 has a short friction stroke, a large load and a large impact with the gear sleeve seat 2, which causes the brake disc to be unstable and have a short service life.
