Description

Technical Field

[0001] This invention relates to the technical field of hinge assembly, and particularly to a hinge assembly machine. Background Technology

[0002] Hinges are used to mount two relatively independent objects, such as a window and its frame, or a door and its frame. Hinges utilize the principle of relative rotation to allow two relatively independent objects to rotate around an axis between an open and closed state. In the assembly process of automated hinge production, hinge assembly machines are used to assemble hinge parts to form a complete hinge. During the hinge assembly process, the hinge assembly machine needs to position each component before assembling it, so that each station assembles according to the preset position, thus assembling the various hinge parts into a whole.

[0003] In existing hinge assembly machines, connecting the hinge rocker arm to the hinge body seat involves two processes. The first process is to drive the rocker arm to the body seat in one station, and the second process is to output a rocker arm connecting pin in another station to hinge the rocker arm to the body seat. These two processes are essential for hinge assembly. The usual design involves completing the rocker arm driving to the body seat and the rocker arm hinged to the body seat in two separate stations. However, due to equipment vibration during operation, or after completing the first process, the machine may cause the rocker arm to engage with the body seat... The inertia generated during the process of the arm moving to the second process can cause the rocker arm and the arm body seat, which have already been positioned in the first process, to become misaligned. This prevents the equipment from completing the second process smoothly, i.e., it cannot complete the hinge connection between the rocker arm connecting pin and the rocker arm and the arm body seat. Furthermore, completing the first and second processes through two separate workstations also requires the turntable to reserve two workstations for the two processes. This also results in the overall structure of the hinge assembly machine being less compact and occupying a large space. Therefore, this invention provides a solution that can reduce the number of workstations in the hinge assembly machine. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a hinge assembly machine.

[0005] To achieve the above objectives, this invention discloses a hinge assembly machine, comprising a base, a rotating disk with a composite workstation, and a composite mechanism assembled with the base. The composite mechanism includes a slanted push assembly and a pin-insertion assembly. The slanted push assembly includes a slanted push block with a mounting position, which pushes a rocker arm positioned at the mounting position toward the composite workstation. The pin-insertion assembly includes a pin-feeding component, a pin-guide component, and a clamp fixedly connected to the base. The clamp holds the pin-feeding component and drives it to move toward the composite workstation. The pin-feeding component is located on the side of the composite workstation closest to the center of the rotating disk, and the pin-guide component is located on the other side of the composite workstation, opposite to the pin-feeding component. The slanted push block pushes the rocker arm to be installed toward the mounting position. The composite workstation aligns the rocker arm with the hinge hole between the rocker arm and the arm body seat. Both the feeding pin and the guiding pin move towards the composite workstation. The chuck outputs the rocker arm connecting pin through the feeding pin, and the guiding pin guides the rocker arm connecting pin through the hinge hole to hinge the rocker arm connecting pin between the arm body seat and the rocker arm. The inclined push assembly also includes a transfer block and a positioning block. The positioning block has a positioning groove that matches the cross-sectional shape of the rocker arm. The opening of the positioning groove has a transfer position for storing the rocker arm to be moved to the installation position. The shape of the transfer block matches the positioning groove and is slidably connected to it. The transfer block slides back and forth between the transfer position and the installation position.

[0006] The inclined push block has a slot for installation, the opening of which faces the composite work station. The slot is through the side of the inclined push block near the positioning slot. The cross-section of the slot is adapted to the cross-section of the rocker arm. The installation position is located in the slot.

[0007] The positioning block has a slanted push hole on its top surface. The slanted push hole is a through hole and its opening faces the composite work station. The slanted push block is slidably connected to the slanted push hole, and the shape of the slanted push hole is adapted to the shape of the slanted push block.

[0008] The composite mechanism includes a rocker arm slide and a vibratory feeder. The rocker arm slide is used to input material into the rocker arm from the vibratory feeder. The inclined push assembly also includes a push block. The top surface of the positioning block is provided with a push groove. The output port of the rocker arm slide is connected to the push groove. A receiving position is provided at the connection between the output port of the rocker arm slide and the push groove. The transfer position is located at the end of the push groove. The positioning groove extends from the push groove to the loading position. The push block slides back and forth between the receiving position and the transfer position.

[0009] The push block has a receiving groove on its top surface. The receiving groove is a through groove. The cross-sectional shape of the receiving groove is adapted to the cross-sectional shape of the rocker arm. The receiving groove is connected to the output port of the rocker arm slide. The receiving position is located in the receiving groove.

[0010] The system also includes a rocker arm lubrication mechanism, which comprises an oil pipe, a vertical plate, and a clearance block. The rotating disk has a rocker arm lubrication station. The vertical plate is fixedly connected to the base. The oil pipe moves back and forth toward the rocker arm lubrication station. The clearance block tilts back and forth from top to bottom toward the rocker arm lubrication station. After the clearance block pushes the rocker arm to rotate away from the torsion spring, the oil pipe approaches the rocker arm lubrication station to lubricate the torsion spring. The rocker arm lubrication mechanism includes a pressing block, which moves back and forth relative to the vertical plate. The pressing block moves back and forth toward the rocker arm lubrication station and presses against the arm body seat. After the pressing block abuts against the arm body seat, the clearance block drives the rocker arm to rotate.

[0011] The rocker arm oiling mechanism includes a support member connected to the vertical plate. A pressure through-hole is formed on the top surface of the support member, extending to the bottom surface and facing the rocker arm oiling station. A pressure block slides back and forth along the pressure through-hole. A clearance hole is formed on the side of the support member, gradually sloping downwards. The clearance hole extends from the side of the support member to the bottom surface, and the clearance block slides along the clearance hole. The pressure through-hole and the clearance hole intersect. The pressure block is inverted U-shaped and obliquely passes between the two arms of the pressure block.

[0012] The bottom surface of the clearance block is provided with a clearance groove. The axial direction of the clearance groove is the same as the radial direction of the rotating disk. The clearance groove is a through groove. The two sides of the clearance groove extend to the side surface and the bottom surface of the clearance block, respectively. When the oil pipe is ignited, the oil pipe passes through the clearance groove.

[0013] The side of the clearance block facing the rocker arm has a forked groove. The forked groove is a through groove. The axial direction of the forked groove is adapted to the extension direction of the connecting member. When the clearance block pushes the rocker arm to rotate, the connecting member is located in the forked groove.

[0014] Compared to existing technologies, the advantages of this invention are as follows: The rocker arm material to be installed is placed in the installation position, i.e., in the installation slot. The inclined push block then moves towards the composite workstation. This is the process of installing the rocker arm onto the arm body seat. The nail feeder and guide nail feeder output rocker arm connecting nails towards the hinge hole between the rocker arm and the arm body seat to hinge the rocker arm onto the arm body seat. This is the process of hinged rocker arm onto the arm body seat. Both the rocker arm installation onto the arm body seat and the rocker arm hinged onto the arm body seat are completed at the composite workstation. This reduces the travel distance of the arm body seat and rocker arm without hinged rocker arm connecting nails, thereby reducing the risk of misalignment between the arm body seat and rocker arm due to vibration during equipment operation. It also avoids the inertia generated during the process of the equipment moving from the first process to the second process, reducing the risk of misalignment between the rocker arm and the arm body seat. This increases the likelihood of smooth hinged connection between the rocker arm connecting nails and the rocker arm and arm body seat, while also improving the overall structural compactness of the hinge assembly machine and reducing its space occupation.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the following will be combined with... Figure 1-17 The state shown is described in terms of orientation and structure.

[0034] The following will combine Figure 1-17 The invention will be further described in detail with reference to the accompanying drawings.

[0035] Reference Figure 1-3 As shown, this invention relates to the assembly of a hinged arm assembly, which includes an arm base 91, a torsion spring 92, a connector 93, a rocker arm 94, a torsion spring connecting pin 95, and a rocker arm connecting pin 96. The torsion spring 92 is sleeved on the outside of the torsion spring connecting pin 95, and the connector 93 is also sleeved on the outside of the torsion spring connecting pin 95 and located in the middle of the torsion spring connecting pin 95, that is, the connector 93 rotates around the torsion spring connecting pin 95. The rocker arm 94 is sleeved on the outside of the rocker arm connecting pin 96, that is, the rocker arm 94 rotates around the rocker arm connecting pin 96. Then, the torsion spring connecting pin 95 and the rocker arm connecting pin 96 are riveted to the arm base 91 respectively, thereby completing the assembly of the hinged arm assembly.

[0036] This invention provides a hinge assembly machine adapted for the automated assembly of the aforementioned hinge arm components, comprising a base 991, a rotating disk 992, an arm seat feeding mechanism 1, an assembly mechanism 2, a connector oiling mechanism 3, a composite mechanism 4, a torsion spring nail riveting mechanism 5, a rocker arm nail riveting mechanism 6, a rocker arm oiling mechanism 7, and a discharge mechanism 8. The rotating disk 992 is rotatably connected to the base 991. Along its circumference, the rotating disk 992 is sequentially provided with an arm seat 91 feeding station, an assembly station, a connector oiling station, a composite station 601, a torsion spring nail riveting station, a rocker arm nail riveting station, a rocker arm oiling station 70, and a discharge station. The arm seat feeding mechanism 1... The following components are installed on the base 991 and correspond to the loading station of the arm body: assembly mechanism 2, connecting component oiling mechanism 3, composite mechanism 4, torsion spring nail riveting mechanism 5, rocker arm nail riveting mechanism 6, rocker arm nail riveting mechanism 7, rocker arm oiling mechanism 7, and discharge mechanism 8.

[0037] The assembly mechanism 2 is used to install the connector 93 and torsion spring 92 onto the arm body seat 91 on the jig 98 of the fusion station, so as to complete the installation of the connector 93, torsion spring 92 and arm body seat 91.

[0038] The present invention improves the composite mechanism 4 and the rocker arm oiling mechanism 7. The composite mechanism 4 is used to install the rocker arm 94 onto the arm body base 91; the rocker arm oiling mechanism 7 is used to apply oil to the rocker arm 94 after it is installed onto the arm body base 91; the rotating disk 992 is rotatably connected to the top surface of the base 991 and is driven to rotate by a motor installed on the base 991.

[0039] The composite mechanism 4 is assembled with the base 991. The rotating disk 992 is provided with a composite station 601 corresponding to the composite mechanism 4. The composite station 601 is located on the top surface of the rotating disk 992 and is located near the outer periphery. The composite mechanism 4 is provided with a waiting position for storing the rocker arm 94 to be installed onto the arm body. The composite mechanism 4 includes a slanting push assembly and a nail-piercing assembly 62. The slanting push assembly includes a slanting push block 611 and a slanting push cylinder 612. The waiting position is located on the slanting push block 611. The slanting push cylinder 612 is installed on the base 991 and drives the slanting push block 611 to move back and forth between the waiting position and the composite station 601. That is, the slanting push block 611 pushes the rocker arm 94 placed in the waiting position toward the composite station 601. The nail-piercing assembly 62 includes a nail feeder 621, a nail guide 622, a clamp 623, and a nail-piercing cylinder 624. Mounted on base 991, the pin-feeding cylinder 624 drives the pin guide 622 to slide back and forth. The chuck 623 is fixedly connected to base 991 and holds the pin feeder 621. The chuck 623 is driven by the cylinder and moves the pin feeder 621 toward the composite station 601. The pin feeder 621 is located on one side of the composite station 601 near the center of the rotating disk 992, that is, on one side of the fixture 98. The pin guide 622 is located on the other side of the composite station 601, that is, on the other side of the fixture 98 and opposite to the pin feeder 621. The pin feeder 621 is aligned with the hinge hole of the rocker arm 94 and the hinge hole of the arm body seat 91. The pin guide 622 is also aligned with the hinge hole of the rocker arm 94 and the hinge hole of the arm body seat 91. The pin guide 622 and the pin feeder 621 are coaxially arranged.

[0040] The material of the rocker arm 94 to be installed is placed in the installation position. The inclined push block 611 then moves towards the composite station 601, pushing the rocker arm 94 to be installed to the composite station 601, so that the rocker arm 94 is aligned with the hinge hole between the rocker arm 94 and the arm body seat 91. The above is the process of installing the rocker arm 94 into the arm body seat 91, which is also the first process in the background technology. The nail feeder 621 and the nail guide 622 both move towards the composite station 601. The chuck 623 outputs the rocker arm connecting nail 96 through the nail feeder 621, so that the rocker arm connecting nail 96 passes through the hinge hole. The nail guide 622 extends into the hinge hole and guides the rocker arm connecting nail 96 through the hinge hole, so as to hinge the rocker arm connecting nail 96 between the arm body seat 91 and the rocker arm 94, thereby installing the rocker arm 94. 4. Hinged onto the boom seat 91. The above is the process of hinged rocker arm 94 onto boom seat 91, which is also the second process in the background technology. The process of installing rocker arm 94 onto boom seat 91 and the process of hinged rocker arm 94 onto boom seat 91 are both completed in the composite station 601. This reduces the travel distance of the boom seat and rocker arm without hinged rocker arm connecting pins, thereby reducing the risk of misalignment between boom seat and rocker arm due to vibration during equipment operation. It also avoids the inertia generated when the equipment moves from the first process to the second process, reducing the risk of misalignment between rocker arm and boom seat. It increases the possibility of smooth hinged connection between rocker arm connecting pins and rocker arm and boom seat, and also improves the overall structural compactness of the hinge assembly machine and reduces the space occupied by the hinge assembly machine.

[0041] Specifically, the chuck 623 is provided with a nail input cylinder 625, with a nail input hole at one end of the nail input cylinder 625 facing outwards. The other end of the nail input cylinder 625 is connected to the nail feeding member 621, and the rocker arm connecting nail 96 is input from the nail input hole, so that the rocker arm connecting nail 96 is output from the nozzle of the nail feeding member 621 to the aforementioned hinge hole.

[0042] It should be noted that in subsequent processes, the rocker arm connecting nail 96 is riveted to the arm body seat 91 by the rocker arm nail riveting mechanism 6.

[0043] When the rocker arm 94 is fed in, it needs to be accurately driven to the loading position. If the rocker arm 94 is not accurately driven to the loading position, misalignment will occur between the rocker arm 94 and the arm body. To solve this problem, the inclined push assembly also includes a transfer block 615, a positioning block 613, and a transfer cylinder 614. The positioning block 613 has a positioning groove 6131 that matches the cross-sectional shape of the rocker arm 94. The opening of the positioning groove 6131 has a transfer position 6132, which is used to store the rocker arm 94 to be moved to the loading position. The shape of the transfer block 615 matches the positioning groove 6131. Furthermore, the transfer block 615 is slidably connected to the positioning groove 6131. ​​The transfer block 615 slides from the transfer position 6132 to the installation position. The transfer cylinder 614 is installed on the base 991. The transfer cylinder 614 drives the transfer block 615 to slide. Through the above settings, the transfer cylinder 614 pushes the transfer block 615 to drive the rocker arm 94 located at the transfer position 6132 into the positioning groove 6131. ​​The positioning groove 6131 limits the tilt angle of the rocker arm 94 so as to accurately push the rocker arm 94 into the installation position. After the rocker arm 94 enters the installation position, the inclined push cylinder 612 drives the inclined push block 611 to install the rocker arm 94 onto the arm body base 91.

[0044] The inclined push block 611 has a mounting slot 6111, the opening of which faces the composite station 601. The mounting slot 6111 is a through slot, extending from the side of the inclined push block 611 near the positioning slot 6131 to the opposite side of the inclined push block 611. The cross-section of the mounting slot 6111 is adapted to the cross-section of the rocker arm 94. The mounting position is located in the mounting slot 6111, that is, the mounting position is formed through the mounting slot 6111. With the above configuration, after the transfer block 615 drives the rocker arm 94 to the mounting position, the mounting slot 6111 plays a positioning role for the rocker arm 94, thereby improving the accuracy of the rocker arm 94 being installed into the arm body seat 91.

[0045] The top surface of the positioning block 613 is provided with a slanted push hole 6133. The slanted push hole 6133 is a through hole, and the opening of the slanted push hole 6133 is set towards the arm seat 91. The axial direction of the slanted push hole 6133 is inclined. The slanted push block 611 is slidably connected to the slanted push hole 6133. The shape of the slanted push hole 6133 is adapted to the shape of the slanted push block 611. With the above settings, the slanted push cylinder 612 drives the slanted push block 611 to slide back and forth towards the arm seat 91 along the extension direction of the slanted push hole 6133. The slanted push hole 6133 plays a limiting role in the sliding of the slanted push block 611, further improving the accuracy of the rocker arm 94 being installed on the arm seat 91.

[0046] The composite mechanism 4 includes a rocker arm slide 61 and a vibratory feeder 64. The rocker arm slide 61 is used to input material from the vibratory feeder 64 into the rocker arm 94. The inclined push assembly also includes a push block 616 and a push cylinder 618. The push cylinder 618 is mounted on the base 991. The top surface of the positioning block 613 is also provided with a push groove 6134. The positioning groove 6131 extends from the push groove 6134 to the position to be installed. The extension direction of the push groove 6134 is perpendicular to the extension direction of the positioning groove 6131. ​​The output port of the rocker arm slide 61 is connected to the push groove 6134. A receiving position 6135 is provided at the connection between the push groove 6134 and the output port of the rocker arm slide 61. A transfer position 6132 is provided at the push groove 6134. At the end of 134, the push cylinder 618 drives the push block 616 to slide back and forth between the receiving position 6135 and the transfer position 6132. Through the above settings, the material of the rocker arm 94 is placed on the vibrating plate 64. The rocker arm 94 is then transported from the rocker arm slide 61 to the output port of the rocker arm slide 61. The rocker arm 94 enters the push groove 6134, that is, the rocker arm 94 is in the receiving position 6135. The push cylinder 618 then drives the push block 616. The push block 616 slides along the push groove 6134, driving the rocker arm 94 to the slot of the positioning groove 6131, that is, the rocker arm 94 is in the transfer position 6132, which is also the end of the push groove 6134. The transfer block 615 then drives the rocker arm 94 to the waiting position.

[0047] The top surface of the push block 616 is provided with a receiving groove 617. The receiving groove 617 is a through groove, and the cross-sectional shape of the receiving groove 617 is adapted to the cross-sectional shape of the rocker arm 94. The receiving groove 617 is connected to the output port of the rocker arm slide 61. With the above arrangement, after the rocker arm 94 enters the receiving groove 617 from the output port of the rocker arm slide 61, the push block 616 can position the rocker arm 94 when driving it, reducing the risk of the rocker arm 94 being misaligned when driven by the push block 616.

[0048] The top wall of the positioning block 613 is provided with a connecting groove 6136. The connecting groove 6136 extends from the side of the positioning block 613 near the input port of the rocker arm slide 61 to the side of the pushing groove 6134. When the receiving groove 617 of the pushing block 616 is located in the receiving position 6135, the connecting groove 6136 and the receiving groove 617 are coaxially arranged.

[0049] The rocker arm lubrication mechanism 7 includes a lubrication cylinder 71, an oil pipe 72, a vertical plate 73, a clearance cylinder 74, and a clearance block 75. The vertical plate 73 is fixedly connected to the base 991. The lubrication cylinder 71 is mounted on the vertical plate 73 and drives the oil pipe 72 to move toward the arm seat 91. The clearance cylinder 74 is mounted on the vertical plate 73 and drives the clearance block 75 to tilt back and forth from top to bottom. The clearance block 75 moves downward and abuts against the rocker arm 94. When connected, the clearance block 75 pushes the rocker arm 94 to rotate relative to the arm seat 91, so that the outward end of the rocker arm 94 rotates and moves away from the arm seat 91. Through the above setting, the clearance cylinder 74 drives the clearance block 75 to move downward. The clearance block 75 pushes the rocker arm 94, so that the rocker arm 94 rotates and moves away from the arm seat 91. Then, the oiling cylinder 71 drives the oil pipe 72 to approach the arm seat 91 to apply oil to the torsion spring 92 and the connecting part 93, specifically lubricating oil.

[0050] The top surface of the base 991 is provided with a fixed circular plate 9911. The circular plate 9911 and the top surface of the base 991 are spaced apart. The rotating disk 992 is located in the space, that is, the circular plate 9911 is located on the upper side of the rotating disk 992. The radius of the rotating disk 992 is larger than the radius of the circular plate 9911. Through the above arrangement, part of the rotating disk 992 is exposed outside the circular plate 9911 for the installation of the fixture 98, so that the rotating disk 992 drives the fixture 98 to rotate circumferentially around the outer side of the circular plate 9911.

[0051] The rocker arm oiling mechanism 7 includes a connecting plate 76, an upright plate 73 extending in the radial direction of the rotating disk 992, an upright plate 73 fixedly mounted on a circular plate 9911, an oiling cylinder 71 mounted on the upright plate 73, an upright plate extension 731 with its end near the top of the circular plate 9911, one side of the connecting plate 76 fixedly connected to the upright plate extension 731, the extending direction of the connecting plate 76 being perpendicular to the extending direction of the upright plate 73, the connecting plate 76 having a connecting plate extension 761, and a clearance cylinder 74 mounted on the connecting plate extension 761. This arrangement allows the clearance cylinder 74 and the oiling cylinder 71 to be staggered.

[0052] The rocker arm lubrication mechanism 7 includes a pressure cylinder 77 and a pressure block 78. The pressure cylinder 77 is mounted on the base 991. The pressure cylinder 77 drives the pressure block 78 to move back and forth toward the arm seat 91 and press against the arm seat 91. Through the above arrangement, the pressure cylinder 77 drives the pressure block 78 to move toward the arm seat 91, and the pressure block 78 abuts against the arm seat 91. Through the above arrangement, the arm seat 91 is positioned to prevent the arm seat 91 from being misaligned when the release block 75 pushes the rocker arm 94, and also improves the stability of the oil pipe 72 when lubricating the torsion spring 92.

[0053] The rocker arm lubrication mechanism 7 includes a support member 79, which is fixedly connected to the other side of the connecting plate 76, i.e., the outward side. The top surface of the support member 79 has a pressing through hole 7912, which extends to the bottom surface of the support member 79. The pressing through hole 7912 is arranged through the rocker arm lubrication station 70, i.e., the opening of the pressing through hole 7912 extends towards the arm seat 91. A pressing cylinder 77 is installed on the support member 79. A pressing block 78 is adapted to the pressing through hole 7912. The pressing cylinder 77 drives the pressing block 78 to move along the pressing through hole 7912 and abut against the arm seat 91. Through the above arrangement, the pressing through hole 7912 guides the pressing block 78, improving the accuracy of the pressing block abutting against the arm seat 91.

[0054] Specifically, the axial direction of the pressure through hole 7912 is set vertically, and the pressure cylinder 77 drives the pressure block 78 to move vertically.

[0055] The side of the support member 79 is provided with a clearance hole 791, which is gradually inclined from top to bottom. The clearance hole 791 extends from the side of the support member 79 to the bottom surface of the support member 79. The clearance block 75 is slidably connected to the inside of the clearance hole 791. The clearance block 75 slides back and forth along the clearance hole 791. Through the above configuration, the clearance hole 791 guides the movement of the clearance block 75, improves the stability of the sliding of the clearance block 75, and improves the accuracy of the clearance block 75 in driving the rocker arm 94 to rotate.

[0056] Reference Figure 15 As shown, the pressing through hole 7912 and the relief hole 791 are intersecting, and the pressing block 78 is located to the side of the relief block 75, as shown in the figure. Figure 17 As shown, the pressing block 78 is arranged in an inverted U-shape, and the yielding block 75 is located between the two arms of the pressing block 78. That is, the two arms of the pressing block 78 are located on both sides of the yielding block 75. Through the above arrangement, the pressing block 78 yields to the pressing block 78.

[0057] The bottom surface of the clearance block 75 is provided with a clearance groove 7911. The two sides of the clearance groove 7911 extend to the side surface and the bottom surface of the clearance block 75, respectively. The clearance groove 7911 is a through groove. The axial direction of the clearance groove 7911 is the same as the radial direction of the rotating disk 992. When the oil pipe 72 is ignited, the oil pipe 72 passes through the inner side of the clearance groove 7911. Through the above arrangement, the clearance groove 7911 plays a role in avoiding the oil pipe 72.

[0058] The bottom surface of the yielding block 75 is provided with a forked groove 7913, that is, the side of the yielding block 75 facing the rocker arm 94 is provided with a forked groove 7913. The forked groove 7913 is a through groove that runs through the top and bottom surfaces of the yielding block 75. That is, the axial direction of the forked groove 7913 is adapted to the extension direction of the connecting member 93. When the yielding block 75 pushes the rocker arm 94 to rotate, the connecting member 93 is located inside the forked groove 7913. The forked groove 7913 plays a role in avoiding the connecting member 93, reducing the possibility of collision between the yielding block 75 and the connecting member 93.
