Description

Technical Field

[0001] The present application relates to the technical field of anchor bolt assembly equipment, and in particular to a sleeve anchor bolt nut washer assembly equipment. Background Art

[0002] There are many types of anchor bolts. Some are expanded and anchored through expansion sleeves, while others are expanded through expansion rings. Therefore, the processing and assembly methods and equipment used for different types of anchor bolts are different.

[0003] Among them, for anchor bolts with sleeves, our company uses self-developed equipment to pre-assemble the anchor rod by vertically inserting it into the sleeve, and then places the anchor rod head upward on an inclined material rack for transmission to the gasket and nut assembly equipment. As shown in the patent application number CN202310455699.X, the existing nut and gasket assembly equipment uses two sets of vibrating unloading racks to respectively drive the gasket and nut to be unloaded, and then they are pushed onto the horizontally placed anchor rod in turn by ejection, and finally the nut is rotated and installed on the anchor rod through the nut-loading tool. In this way, multiple workstations are required, with one workstation for gasket installation, one workstation for nut installation, and one workstation for nut tightening. Although automation has been achieved, efficiency still needs to be improved, and the focus is on simplifying the workstation steps. Summary of the Invention

[0004] In order to improve the defects of the existing automatic assembly equipment of gasket nuts and anchor rods, which has many workstation steps and low efficiency, the present application provides a sleeve anchor nut gasket assembly equipment.

[0005] The present application provides a sleeve anchor nut washer assembly device that adopts the following technical solutions:

[0006] A sleeve anchor nut washer assembly device, comprising

[0007] The unloading rack is tilted and is used to receive the anchor rod with sleeve;

[0008] The auxiliary frame is also tilted and located at the end of the unloading frame. A rotating rod is provided on the rotating frame at the bottom. Guard plates are fixed at both ends of the rotating rod. The guard plates can be overlapped on the auxiliary frame. A pocket plate is fixed at the end of the guard plate. The pocket plate is located between the auxiliary frame and the unloading frame. The rotating rod is driven to rotate and reset by a motor.

[0009] The workstation turntable has a vertically arranged rotating shaft, and a plurality of slots are provided on the circumferential outer wall. The anchor sleeve on the auxiliary frame can be placed on the top of the slot edge. A mounting cylinder is provided on the upper surface of the workstation turntable, and a first motor is provided on the central axis of the workstation turntable to drive its own rotation.

[0010] The magnetic plate is arranged on the outer circumferential wall of the installation cylinder and is located opposite to the card slot;

[0011] The parts turntable is arranged below the workstation turntable, is coaxial with the workstation turntable and rotates together with it, has a parts slot on its upper surface facing the card slot, and has an ejection hole at the bottom of the parts slot;

[0012] The parts tray is placed in the parts slot, with a nut slot on the upper surface. Six nut blocks are fixed at equal intervals on the inner wall of the nut slot. The space between the nut blocks and the upper surface of the parts tray is for placing gaskets.

[0013] There are two vibrating unloading trays, which are set on one side of the parts turntable. One is for placing nuts and the other is for placing gaskets. The discharge ports are both provided with downward-inclined unloading plates, with the ends pointing above the parts slot. In the direction of rotation of the parts turntable, the unloading plates of the nuts are passed first, and then the unloading plates of the gaskets.

[0014] The ejection cylinder is arranged below the parts tray, and the piston rod is rotatably connected to a gear column. The outer wall of the gear column is provided with teeth and meshes with a transmission gear. A second motor is arranged below the transmission gear, and the rotating shaft of the second motor is fixedly connected to the transmission gear. The gear column can extend into the ejection hole to drive the parts tray to move up and rotate. The parts turntable passes over the ejection cylinder only after passing the auxiliary frame.

[0015] The down-pressing cylinder is installed above the workstation turntable and above the ejection cylinder. After the piston rod is extended, it presses the top of the anchor rod;

[0016] The ejector assembly is arranged on the work station turntable and is used to eject the anchor rod passing above the ejector cylinder from the slot for unloading.

[0017] Using this technical solution, the sleeved anchor rod slides down from the unloading rack onto the auxiliary rack, where it is intercepted by a slot. The motor then drives the rotating rod, causing the pocket plate to abut the anchor rod's sleeve and flip it until it engages and secures with the magnetic plate. The anchor rod then rotates within the slot along with the workstation turntable. The vibrating unloading tray, through vibration, sequentially places the nut and washer onto the parts tray. The parts tray, restrained by a nut block, restrains the nuts. The stacked nuts and washers rotate to the ejector cylinder, where the piston rod extends, causing the toothed column to eject the parts tray, placing the washer and nut onto the threaded rod. Simultaneously, the downward pressure cylinder pushes the anchor rod in place. A second motor drives the transmission gear, which in turn rotates the toothed column, threading the nut onto the anchor rod, completing the installation of the nut and washer. Finally, when the unloading position is reached, the ejector assembly ejects the anchor rod from the slot. This enables automated assembly of nuts and washers onto the anchor rod at a single workstation, effectively improving the efficiency of anchor bolt assembly.

[0018] Optionally, the top of the gear column and the lower surface of the parts tray are both provided with ring teeth, which can engage with each other.

[0019] Optionally, an anti-slip ring groove is opened on the circumferential inner wall of the parts slot, an anti-slip ring plate is fixed on the bottom of the circumferential outer wall of the parts tray, and a reset spring is fixed on the top wall of the anti-slip ring groove, and the reset spring is tightly pressed against the anti-slip ring plate.

[0020] Optionally, a plurality of reset blocks are fixedly provided at equal intervals on the bottom of the circumferential inner wall of the anti-slip ring groove, the top of the reset block is set as a pointed end, and a plurality of inclined guide grooves are opened at equal intervals on the circumferential outer wall of the anti-slip ring plate, the bottom opening of the guide groove is larger than the top opening, and when the reset block abuts against the top of the inner wall of the guide groove, the direction of the nut block is the same as before it was ejected.

[0021] Optionally, avoidance grooves of the same size are provided at the bottom of the parts tray and the top of the tooth column for the bottom end of the anchor rod to extend into.

[0022] Optionally, a retaining arc plate is set above the work station turntable. After the anchor rod is located in the slot and rotates with the work station turntable, the sleeve will abut against the retaining arc plate and separate after passing above the ejection cylinder.

[0023] Optionally, an arc-shaped baffle is provided at the end of the blanking plate so that the nuts and washers abutting the arc-shaped baffle fall onto the parts tray.

[0024] Optionally, the ejection assembly includes a fixed protrusion and an ejection plate;

[0025] The fixed protrusion is mounted in the mounting tube. The outer circumferential wall of the mounting tube is provided with discharge holes at the top and bottom of the magnetic plate. The ejection plate is slidably connected to the discharge holes. The edge of the ejection plate in the mounting tube is raised and fixed with a compression spring. The other end of the compression spring is pressed against the inner wall of the mounting tube, so that the ejection plate is always in contact with the fixed protrusion.

[0026] When the anchor rod is rotated to a position where ejection is required, the fixed protrusion causes the ejection plate to extend.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] After the anchor rod slides into the slot, the motor rotates and drives the pocket plate to flip the anchor rod, so that the sleeve is adsorbed on the magnetic plate, and then the anchor rod head with the sleeve is upright, so as to facilitate the simultaneous assembly of the nut and gasket at the next workstation.

[0029] The nut falls from the blanking plate to the parts tray under the vibration of the vibrating blanking tray. After the parts turntable rotates, the gasket falls onto the nut block under the rotation of the vibrating blanking tray and rotates with the workstation turntable. The parts tray is ejected at the ejection cylinder, so that the gasket and nut are sleeved on the bottom of the anchor rod and the nut is installed by rotation. Then, the gasket and nut are assembled on the anchor rod at the same time at one workstation, which improves the assembly efficiency.

[0030] The parts tray can limit the rotation of the nut through the nut block, thereby stably driving the nut to rotate. The engagement of the ring teeth of the parts tray and the gear column can also stably drive the parts tray to rotate;

[0031] The setting of the reset spring can make the parts tray automatically reset, and can make the parts tray rotate to a relatively initial position under the abutment of the reset block and the guide groove, so that the nut can fall into the parts tray normally and stably, facilitating the realization of automation;

[0032] When the anchor rod rotates to the position where unloading is required, the contour of the fixed protrusion causes the ejection plate to extend, thereby ejecting the anchor rod from the slot to complete unloading, thereby realizing automatic unloading after the anchor rod assembly is completed and improving the efficiency of anchor rod assembly.

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] The embodiment of the present application discloses a sleeve anchor bolt nut washer assembly device.

[0041] refer to Figure 1 The sleeve anchor nut gasket assembly equipment includes a blanking rack 1, a flipping assembly 2, a work station turntable 3, a parts turntable 4, a vibrating blanking disc 9, an ejection cylinder 6, a downward pressure cylinder 7 and an ejection assembly 8. The blanking rack 1 is tilted to receive the anchor rod with the sleeve and drive the anchor rod to slide downward in sequence. The rotating axis of the work station turntable 3 is vertically arranged, and a plurality of slots 31 are equidistantly provided on the circumferential outer wall. The slots 31 allow the anchor rod to pass through but not the sleeve. The flipping assembly 2 is arranged between the blanking rack 1 and the work station turntable 3, and is used to erect the anchor rod and place it in the slot 31. A mounting cylinder 32 is fixed in the middle position of the upper surface of the work station turntable 3, and a magnetic plate 321 is fixed on the circumferential outer wall of the mounting cylinder 32 facing the slot 31. The magnetic plate 321 can attract and fix the sleeve of the anchor bolt located in the slot 31. A first motor 33 is provided at the bottom of the workstation turntable 3 , and the first motor 33 drives the workstation turntable 3 to rotate intermittently.

[0042] refer to Figure 2 and Figure 3 The parts turntable 4 is located below the workstation turntable 3 and is fixed to the workstation turntable 3 and rotates coaxially. A parts slot 41 is provided on the upper surface of the parts turntable 4 at a position opposite to the slot 31, and an ejection hole 42 is provided in the middle of the bottom of the parts slot 41. A parts tray 5 for receiving nuts and gaskets is provided in the parts slot 41. There are two vibrating unloading trays 9, which are arranged on one side of the parts turntable 4, one for placing nuts and the other for placing gaskets. The discharge ports of the vibrating unloading trays 9 are all provided with downwardly inclined unloading plates 91, with the ends pointing above the parts slot 41. In the rotation direction of the parts turntable 4, the unloading plates 91 of the nuts are passed first, and then the unloading plates 91 of the gaskets are passed. An arc-shaped baffle 91 is provided at the end of the unloading plate 91, so that the nuts and gaskets that abut against the arc-shaped baffle 911 fall onto the parts tray 5.

[0043] The ejection cylinder 6 is arranged below the part tray 5, and the piston rod is rotatably connected to a gear column 61. The gear column 61 has teeth distributed on the circumferential outer wall and is meshed with a transmission gear 62. A second motor 621 is arranged below the transmission gear 62, and the rotating shaft of the second motor 621 is fixedly connected to the transmission gear 62. The gear column 61 can extend into the ejection hole 42 to drive the part tray 5 to move up and rotate. The part turntable 4 passes over the ejection cylinder 6 only after passing the auxiliary frame 21. Annular teeth are provided on the top of the gear column 61 and the lower surface of the part tray 5, and can mesh with each other. The downward pressure cylinder 7 is mounted above the workstation turntable 3 and is located above the ejection cylinder 6. After the piston rod is extended, it presses the top of the anchor rod. The ejection assembly 8 is arranged on the workstation turntable 3, and is used to eject and unload the anchor rod passing over the ejection cylinder 6 from the slot 31.

[0044] The anchor bolt with the sleeve on slides down on the unloading rack 1 and moves into the slot 31 through the flip assembly 2, so that the bottom end of the sleeve abuts against the upper surface of the work station turntable 3, and the bottom end of the anchor rod extends from the bottom of the slot 31 and is fixed by the magnetic plate 321, so that the anchor rod can rotate with the work station turntable 3. The vibrating unloading tray 9 places nuts and washers respectively, and drives the nuts and washers to fall to the top of the part tray 5 in sequence through the unloading plate 91. During the rotation of the part turntable 4, the nuts are first placed in the part tray 5, and then the washers are placed on the part tray 5 and located above the nuts. After the part tray 5 drives the nuts and washers to move to the top of the ejection cylinder 6, the piston rod of the ejection cylinder 6 extends, the gear column 61 is located in the ejection hole 42 and ejects the nut tray. The second motor 621 drives the transmission gear 62 to rotate, and the transmission gear 62 drives the gear column 61 to rotate. The gear column 61 drives the part tray 5 to rotate through the engagement of the gear ring. At the same time, under the pressure of the anchor rod by the lower pressure cylinder 7, the nut is threadedly connected to the bottom of the anchor rod, completing the rapid assembly of the nut and washers with the anchor rod at one station, thereby improving the efficiency of anchor rod assembly. After the station turntable 3 rotates, the assembled anchor bolt is ejected by the ejection assembly 8 to complete the unloading.

[0045] refer to Figure 2 The flipping assembly 2 includes an auxiliary frame 21, a rotating rod 22, a guard plate 23 and a pocket plate 24. The auxiliary frame 21 is tilted and located at the end of the unloading frame 1, with the bottom of the auxiliary frame 21 facing the card slot 31. The rotating rod 22 is rotatably mounted at the end of the auxiliary frame 21. There are two guard plates 23, which are fixed at both ends of the rotating rod 22 and abut against both sides of the auxiliary frame 21. The pocket plate 24 is fixedly connected to the two guard plates 23, is an arc-shaped plate, and is located between the auxiliary frame 21 and the unloading frame 1. The anchor rod falls onto the auxiliary frame 21, which enables the sleeve to be stuck at the edge of the card slot 31. The rotating rod 22 is driven by the motor to rotate and drive the anchor rod to flip. This allows the anchor rod on the auxiliary frame 21 to be stably stuck in the card slot 31 and adsorbed on the magnetic plate 321.

[0046] refer to Figure 3 and Figure 4A nut slot 51 is defined at the center of the upper surface of the parts tray 5. Six nut blocks 52 are fixedly positioned equidistantly along the circumferential inner wall of the nut slot 51. The space between the nut blocks 52 and the upper surface of the parts tray 5 is provided for the placement of gaskets. An anti-slip ring groove 43 is defined along the circumferential inner wall of the parts slot 41. An anti-slip ring plate 54 is fixedly positioned at the bottom of the circumferential outer wall of the parts tray 5. A return spring 45 is fixedly positioned within the top wall of the anti-slip ring groove 43, which presses against the anti-slip ring plate 54. Multiple return blocks 44 are fixedly positioned equidistantly along the circumferential inner bottom wall of the anti-slip ring groove 43. The tops of the return blocks 44 are pointed. The anti-slip ring plate 54 is defined by multiple, equidistant, inclined guide slots 541 along the circumferential outer wall. The bottom opening of the guide slots 541 is larger than the top opening. When the return blocks 44 abut the top of the inner wall of the guide slots 541, the orientation of the nut blocks 52 remains the same as before ejection. Equally sized avoidance slots 53 are defined at the bottom of the parts tray 5 and at the top of the tooth column 61, allowing the bottom end of the anchor rod to extend into.

[0047] After the nut falls into the nut slot 51, the nut contacts the two side walls of the blanking plate 91, allowing the nut to fall precisely between the nut blocks 52. The gasket then falls onto the nut blocks 52. After moving to the top of the ejector cylinder 6, the parts tray 5 is ejected by the tooth column 61. As the tooth column 61 rotates, the parts tray 5 drives the nut to rotate through the contact between the nut blocks 52 and the nut side walls, thereby threading the nut into the anchor rod and assembling the nut and the anchor rod. The provision of the nut block 52 not only increases the margin for error after the nut falls, but also effectively drives the nut to rotate, while also providing space for the gasket.

[0048] After the ejection cylinder 6 is reset, the parts tray 5 is reset under the action of the reset spring 45. During the reset process of the parts tray 5, the reset block 44 abuts against the guide groove 541 through the tip, and drives the parts tray 5 to rotate to the default angle position through the change of the guide groove 541, thereby facilitating the normal falling of the nut.

[0049] refer to Figure 5 The ejection assembly 8 includes a fixed protrusion 81 and an ejection plate 82. The fixed protrusion 81 is mounted in the mounting tube 32. The circumferential outer wall of the mounting tube 32 is provided with a discharge hole 322 at the top and bottom of the magnetic plate 321. The ejection plate 82 is slidingly connected to the discharge hole 322. The ejection plate 82 is provided with a raised edge in the mounting tube 32 and is fixed with a compression spring 821. The other end of the compression spring 821 is pressed against the inner wall of the mounting tube 32, so that the ejection plate 82 is always in contact with the fixed protrusion 81. When the anchor rod rotates to the position where ejection is required, the fixed protrusion 81 extends the ejection plate 82. A retaining arc plate 34 is mounted above the workstation turntable 3. After the anchor rod is located in the slot 31 and rotates with the workstation turntable 3, the sleeve will abut against the retaining arc plate 34 and separate after passing over the ejection cylinder 6.

[0050] After the anchor rod is attracted to the magnetic plate 321, the arc plate 34 will abut against the side wall of the sleeve as the workstation turntable 3 rotates, further improving the stability of the workpiece movement. When the assembled anchor rod needs to be unloaded, the anchor rod rotates until the sleeve is separated from the arc plate 34, and then the installation cylinder 32 rotates until the ejection plate 82 abuts against the protruding part of the fixed cam, thereby ejecting the ejection plate 82. The ejection plate 82 separates the assembled anchor rod from the magnetic plate 321, thereby realizing automatic unloading of the assembled anchor rod. The ejection plate 82 then rotates until it is separated from the protruding part of the fixed cam and resets.

[0051] The operating principle of the sleeve anchor nut and gasket assembly equipment of the present embodiment is as follows: the sleeved anchor rod falls from the unloading rack 1 onto the auxiliary rack 21 and, under the flipping of the pocket plate 24, is attracted to the magnetic plate 321 and is then held in the slot 31. The nut and gasket are then sequentially dropped into the parts tray 5 at different workstations by the vibrating unloading plate 9 and unloading plate 91 and stacked. After the nut and gasket rotate above the ejection cylinder 6, the ejection cylinder 6 drives the tooth column 61 to extend and eject the parts tray 5. Simultaneously, the down-pressing cylinder 7 moves downward, pressing the anchor rod tightly. The gasket and nut are then sleeved onto the bottom end of the anchor rod. The second motor 621 then rotates, driving the tooth column 61 to rotate, which in turn drives the nut to rotate and install at the bottom end of the anchor rod, completing the assembly of the anchor rod. Finally, after the anchor rod rotates with the workstation turntable 3 to a position where the ejection plate 82 abuts the raised portion of the fixed protrusion 81, the ejection plate 82 extends, ejecting the assembled anchor rod and completing the unloading of the anchor rod. The installation of nuts and washers on anchor rods is achieved through one workstation, which improves the efficiency of assembling anchor bolts with sleeves.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
