An expansion anchor assembly apparatus

Abstract

The application discloses an expansion anchor bolt assembling equipment, which comprises a rack, a clamping mechanism, a lower rotating mechanism and a feeding and discharging mechanism, the clamping mechanism comprises an eccentric frame, a pushing frame, a clamping frame, a fixing frame and an extrusion mechanism, and the adjusting mechanism comprises a driving groove, a lifting frame, a telescopic clamping column, a pressing groove and an elastic pad. The eccentric frame drives the pushing frame to extend or contract, thereby driving two symmetrical clamping frames to move oppositely, so that the anchor bolt assembly is clamped, and the abrasion of nuts and the like caused by being thrown off by a rotating disc is avoided by an arc-shaped plate. The clamping mode can improve the quality of the assembled product, and the limiting and fixing of the nuts by the extrusion mechanism can ensure that the subsequent lower rotation of the anchor rod is not affected. The self-rotation and descent of the lifting frame can make the lower rotation and installation of the anchor rod more stable, and can avoid the thread abrasion caused by forced lower rotation. The originally used mechanical hand is cancelled, the use of devices related to the mechanical hand is reduced, and the cost is reduced.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of expansion anchor assembly equipment, in particular to an expansion anchor assembly equipment. BACKGROUND

[0002] Anchors are divided into various types, some of which are expanded and anchored by expansion sleeves, and some of which are expanded by expansion rings, so the processing and assembly methods and the equipment used for different types of anchors are different. Among them, the anchor with sleeve is pre-assembled by the self-developed equipment of the company in the following way: two sets of vibration blanking racks drive the gaskets and nuts to be blanked respectively, and then the sleeve and the anchor rod are vertically inserted into the sleeve. Finally, the anchor rod is rotated and installed into the nut after the mechanical gripper abuts against the anchor rod, and the anchor rod is ejected.

[0003] After the nuts and gaskets are blanked, the turntable will continue to drive them to rotate. In order to avoid the nuts and gaskets from being gradually offset and dislocated by centrifugal force during rotation, an arc plate is usually used to abut against the nuts and gaskets to limit them. In order to rotate the anchor rod downward to engage it with the nut, an abutting rod is installed at the center of the mechanical gripper. After the abutting rod abuts against the anchor rod, the mechanical gripper grabs the anchor rod to rotate downward and engage it. Therefore, in order to reduce the friction between the arc plate and the nuts and gaskets, avoid damage to the threads caused by forced rotation when the threads of the anchor rod do not correspond to the threads of the nut, improve product quality, and reduce assembly cost, it is necessary to design an expansion anchor assembly equipment.

[0004] It should be noted that the above content belongs to the technical cognition of the inventor and does not necessarily constitute prior art. SUMMARY

[0005] Therefore, it is necessary to provide an expansion anchor assembly equipment in view of the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the present application provides an expansion anchor assembly equipment, comprising:

[0007] The rack comprises a turntable, and the turntable is rotationally installed on the rack;

[0008] The clamping mechanism comprises an eccentric frame, a pushing frame, a clamping frame, a fixing frame, and an extrusion mechanism. The eccentric frame is fixedly installed on the rack, the pushing frame is slidingly connected to the turntable, and the clamping frame is symmetrically arranged and slidingly connected to the turntable. When the turntable rotates to different positions, the eccentric frame can drive the pushing frame to move radially along the turntable, so that the two symmetrically arranged clamping frames can be pulled and relatively displaced by the pushing frame. The fixing frame is fixedly installed on the turntable, and the clamping frame and the fixing frame are provided with extrusion mechanisms for extruding the clamping pieces;

[0009] The lower rotating mechanism comprises a driving groove, a lifting frame, telescopic clamping columns, an elastic mechanism, a lower pressing frame, a lower pressing groove and an elastic pad. The driving groove is arranged on a fixed frame. The driving groove is in a wavy curve shape. The depth of the driving groove changes in steps. The bending part is the starting point of the next step. The lifting frame is rotationally connected to the fixed frame. A plurality of telescopic clamping columns are installed on the lifting frame. The telescopic clamping columns are slidingly clamped in the driving groove. The lifting frame is provided with the elastic mechanism for supporting the lifting frame to be lifted up. The fixed frame is provided with the lower pressing frame. A plurality of lower pressing grooves are arranged on the lower pressing frame. The lifting frame abuts against the lower pressing groove and is lifted along the arc-shaped lifting curve of the lower pressing groove. The lower pressing groove is provided with the elastic pad for pressing the anchor rod.

[0010] The feeding and discharging mechanism is used for feeding nuts, gaskets, sleeves and anchor rods and discharging the expansion anchor bolt after assembly.

[0011] By adopting the above technical scheme, the stepping motor can drive the rotating disc to rotate, so that the rotating disc can drive the clamping frame and the fixing frame thereon to rotate to the feeding and discharging positions of the feeding and discharging mechanism, stop feeding and discharging, and then rotate. The rotating disc drives the slidingly connected pushing frame, clamping frame and fixing frame thereon to rotate, so that the sliding connection of the pushing frame and the eccentric frame and the eccentric setting of the eccentric frame relative to the rotating disc enable the eccentric frame to drive the pushing frame to move radially on the rotating disc to different positions when the rotating disc rotates to different positions. The sliding connection of the pushing frame and the clamping frame enables the two symmetrically arranged clamping frames to move relative to each other when the pushing frame moves to different positions. When the distance between the two clamping frames is large, the nut, washer, sleeve and anchor rod can be inserted into the clamping frame and fixing frame by the feeding and discharging mechanism. During the insertion process, the distance between the two clamping frames gradually decreases under the driving of the pushing frame. The large contact area between the nut, washer and the rotating disc and the clamping frame makes it difficult for them to slip out. Then, when the sleeve and anchor rod are placed, the clamping frame has been reduced to a small distance to clamp the nut and washer. The anchor rod is inserted when the distance between the two clamping frames is the smallest, so that the anchor rod can be aligned with the center of the nut. At this time, the extrusion mechanism is in a compressed state. Then, the rotating disc continues to rotate to tighten the anchor rod. At this time, the distance between the two clamping frames gradually increases, but the extrusion of the nut by the extrusion mechanism enables the anchor rod to still be tightened by rotating downward. When the rotating disc continues to rotate and the extrusion force of the extrusion mechanism on the nut is weak, the anchor rod has been driven to rotate downward by a certain distance. Then, even if the nut moves, the anchor rod can still continue to rotate downward, so the friction between the nut and the original arc-shaped limiting plate is reduced. In order to elastically rotate the anchor rod, avoid forced pressing to cause thread wear, after the feeding is completed, the fixing frame continues to be driven by the rotating disc to rotate so that the top end of the fixing frame can abut against a plurality of downward pressing grooves on the downward pressing frame. The elastic mechanism drives the lifting frame to be elastic, the downward pressing groove drives the lifting frame to descend, and the lifting frame slides up and down on the fixing frame. When the lifting frame rises or descends, the telescopic clamping column thereon can slide in the driving groove on the fixing frame, and the lifting frame can be driven by the telescopic clamping column to rotate around the fixing frame through the fluctuation curve of the driving groove. The telescopic clamping column can automatically pop out at the bending part of the driving groove and be clamped at the next step to continue to slide along the driving groove without rotating, thereby avoiding thread wear caused by forced rotation of the mechanical hand and reducing production cost. The diameter of the rotating disc can be increased to install more clamping frames thereon and the length of the downward pressing frame can be increased to rotate the anchor rod to different depths. The lower part of the clamping frame after the nut is clamped can be provided with a through hole for the anchor rod to rotate out. The driving groove can be a continuous wave line type, a continuous V line type and the like.

[0012] Optionally, the arc length between the adjacent highest point and the lowest point in the pressing groove is greater than or equal to the arc length between the adjacent highest point and the lowest point in the driving groove, and the vertical distance between the adjacent highest point and the lowest point in the pressing groove is greater than or equal to the vertical distance between the adjacent highest point and the lowest point in the driving groove.

[0013] By adopting the above technical scheme, in the case of equal, the lifting frame is always in abutment with the pressing groove, and when the adjacent highest point slides to the lowest point on the pressing groove, the telescopic clamping column driven to rotate can be just from the adjacent highest point to the lowest point on the pressing groove, so that the pressing of the lifting frame is not incomplete, and the telescopic clamping column cannot drive the lifting frame to rotate. In the case of greater than, the lifting frame is not in abutment with the top end of the pressing groove, that is, the lifting frame is only in abutment with the two sides of the pressing groove, and when the lifting frame slides along the side wall of the pressing groove to the bottom end, the lifting frame can be completely pressed down, so that the telescopic clamping column can be clamped into the next step of the driving groove.

[0014] Optionally, the lifting frame is arc-shaped and has a circumference greater than that of a half concentric circle, so that at least two telescopic clamping columns are located in the driving groove during rotation of the lifting frame.

[0015] By adopting the above technical scheme, the lifting frame and the fixed frame are concentric and arc-shaped, the arc length of the lifting frame is greater than half the circumference of the concentric circle, that is, the lifting frame is always in abutment with the fixed frame, so that the lifting frame is prevented from falling off, and the lifting frame can be a complete ring, the nut and the gasket are inserted at the bottom, and the sleeve and the anchor rod are dropped from the top, so that the lifting frame can be popped up after the anchor rod is tightened, and there is space for the anchor bolt to be pushed out after assembly. When the lifting frame is arc-shaped, at least two telescopic clamping columns are located in the driving groove, so that the lifting frame is limited, and the lifting frame is also prevented from falling off.

[0016] Optionally, the rack further comprises a rotary driving device, a gear and an annular gear ring, the rotary driving device is installed on the rack, the output end of the rotary driving device is provided with the gear, the annular gear ring is installed on the rotating disc, and the gear and the annular gear ring are in meshing connection.

[0022] Optionally, the clamping frame is provided with a half-conical frame, the top end of the half-conical frame abuts against the pressing groove, and the half-conical frame is provided with a slot for placing the anchor rod and the sleeve on one side.

[0023] By adopting the technical scheme, the half-conical frame can be replaced directly after wear, and since the lifting frame may only rotate one-third or one-fourth of the length of the concentric circle when passing through one pressing groove, the number of the pressing grooves needs to be set so that the slot on the half-conical frame on the lifting frame can still face outward after passing through all the pressing grooves, thereby facilitating the next time of placing the anchor rod and the sleeve.

[0025] By adopting the technical scheme, the V-shaped frame limits the corners of the nut, the gap between the arc-shaped block and the V-shaped frame limits the annular gasket, and the arc-shaped block limits the sleeve.

[0026] Optionally, the extrusion mechanism comprises a sliding groove, a sliding block and a spring one, the sliding groove is arranged on the side of the V-shaped frame away from the pushing frame and on the fixed frame, the sliding block is slidingly clamped in the sliding groove, and the spring one is mounted in the sliding groove and connected with the sliding groove at the output end.

[0029] By adopting the above technical solution, the telescopic clamping column is slidingly clamped on the lifting frame and is extruded by the second spring, so that the telescopic clamping column has elasticity and can be popped out and clamped into the next step when sliding in the driving groove.

[0030] Optionally, the elastic mechanism comprises a plurality of abutting shafts and a third spring, the abutting shafts are slidingly clamped in the lifting frame, an output end of the abutting shafts abuts against the fixed frame, and an output end of the third spring is connected with the abutting shafts.

[0031] By adopting the above technical solution, the abutting shafts slide in the lifting frame and are extruded by the third spring, and the output end of the abutting shafts abuts against the fixed frame, so that the lifting frame can be lifted up by the pressure of the third spring on the abutting shafts after being pressed down.

[0032] Optionally, one side of the abutting shaft in the rotation direction is provided with a chamfer.

[0034] Optionally, the elastic pads are smooth soft pads, and the upper and lower ends of the elastic pads are provided with chamfers.

[0035] By adopting the above technical solution, when the sleeve falls between the elastic pads, the anchor rod also falls under its own gravity and can fall through the smooth surface of the elastic pads and the chamfer, and then in the process of rotating downward, the chamfer at the lower side of the elastic pad elastically extrudes the anchor rod so that the anchor rod can be driven to rotate downward, and the chamfer can prevent the anchor rod from being lifted up by the elastic pad when the elastic pad is lifted up; the length of the elastic pad is adapted to the length of the lifting frame.

[0036] Optionally, the feeding and discharging mechanism comprises two vibrating discharging discs and a mechanical arm, the two vibrating discharging discs are arranged on one side of the rotating disc, one is used for placing the nut and the other is used for placing the gasket, the outlet end of the vibrating discharging disc points to the fixed frame, and in the rotation direction of the rotating disc, the vibrating discharging disc for the nut is first passed, and then the vibrating discharging disc for the gasket is passed, and the mechanical arm places the sleeve and the anchor rod in the clamping frame and the fixed frame from above after the rotating disc passes the vibrating discharging disc.

[0037] By adopting the above technical solution, the feeding is facilitated, the nut and the gasket are pushed into the fixed frame and the clamping frame by the vibrating discharging disc when the rotating disc drives the fixed frame to rotate to the vibrating discharging disc, and then the sleeve and the anchor rod are sequentially put into the fixed frame and the clamping frame from above by the mechanical arm, so that the assembly of the expansion anchor bolt can be completed after the anchor rod is rotated downward.

[0038] Optionally, the feeding and discharging mechanism further comprises an ejection cylinder, the ejection cylinder is installed on the eccentric frame, the fixed frame is provided with an ejection slot through which the ejection cylinder extends and retracts, and the fixed frame passes through the ejection cylinder after passing through the pressing frame.

[0042] The technical scheme has at least the following beneficial effects:

[0043] 1. The pushing frame on the rotating disc is driven by the eccentric frame to extend or retract, thereby driving the two symmetrical clamping frames to move oppositely, so that the expansion anchor assembly can be clamped after feeding, compared with the previous wear caused by the nut being thrown off by the rotating disc, the clamping mode can improve the quality of the assembled product, and the limiting and fixing of the nut by the extrusion mechanism can ensure that the subsequent rotation of the anchor rod is not affected.

The lifting frame can also rotate in the same direction when being pressed down by the pressing frame, so that the lifting frame rotates and descends, and the extrusion of the anchor rod by the elastic pad can make the rotation and installation of the anchor rod more stable, thereby avoiding the thread wear caused by forced rotation.

[0045] 3.

DETAILED DESCRIPTION

[0057] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different manners, which are different from those described herein, and it can be apparent that similar modifications can be made by those skilled in the art without departing from the scope of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0058] Referring to Figures 1 to 10 The embodiment of the application provides an expansion anchor assembling device, which comprises:

[0059] The rack 1 comprises a rotating disc 11 rotatably arranged on the rack 1.

[0060] The clamping mechanism 2 comprises an eccentric frame 21, a pushing frame 22, clamping frames 23, a fixing frame 24 and an extrusion mechanism 25. The eccentric frame 21 is fixedly arranged on the rack 1. The pushing frame 22 is slidingly connected to the rotating disc 11. The clamping frames 23 are symmetrically arranged and are slidingly connected to the rotating disc 11. When the rotating disc 11 rotates to different positions, the eccentric frame 21 can drive the pushing frame 22 to radially displace along the rotating disc 11, so that the two symmetrically arranged clamping frames 23 can be pulled and relatively displaced by the pushing frame 22. The fixing frame 24 is fixedly arranged on the rotating disc 11. The extrusion mechanisms 25 for extruding the nuts are arranged on the clamping frames 23 and the fixing frame 24.

[0061] The rotating-down mechanism 3 comprises a driving groove 31, a lifting frame 32, telescopic clamping columns 33, an elastic mechanism 34, a pressing-down frame 35, pressing-down grooves 36 and elastic pads 37. The driving groove 31 is arranged on the fixing frame 24. The driving groove 31 is in a wavy curve shape. The depth of the driving groove 31 changes in a stepped manner, and the bending part is the starting point of the next step. The lifting frame 32 is rotatably connected to the fixing frame 24. The telescopic clamping columns 33 are arranged on the lifting frame 32 and slidingly connected to the driving groove 31. The elastic mechanism 34 is arranged on the lifting frame 32 and used for supporting the lifting frame 32 to be lifted. The pressing-down frame 35 is arranged on the rack 1. The pressing-down grooves 36 are arranged on the pressing-down frame 35. The lifting frame 32 and the pressing-down grooves 36 abut and are lifted along the arc-shaped lifting curve of the pressing-down grooves 36. The elastic pads 37 for pressing down the anchor rods are arranged on the pressing-down grooves 36.

[0062] The feeding and discharging mechanism 4 is used for feeding the nuts, the gaskets, the sleeves and the anchor rods and discharging the expansion anchors after the assembling is completed.

[0063] The stepping motor can drive the rotating disc 11 to rotate, so that the rotating disc 11 can drive the clamping frame 23 and the fixing frame 24 thereon to rotate to stop at the upper and lower feeding positions of the feeding and discharging mechanism 4 for feeding and discharging, and then rotate. The rotating disc 11 drives the slidingly connected pushing frame 22, clamping frame 23 and fixing frame 24 to rotate, so that the sliding connection of the pushing frame 22 and the eccentric frame 21 and the eccentric arrangement of the eccentric frame 21 relative to the rotating disc 11 enable the eccentric frame 21 to drive the pushing frame 22 to move radially on the rotating disc 11 to different positions when the rotating disc 11 rotates to different positions. The sliding connection of the pushing frame 22 and the clamping frame 23 enables the two symmetrically arranged clamping frames 23 to move relatively when the pushing frame 22 moves to different positions, so that when the distance between the two clamping frames 23 is large, the nut, the gasket, the sleeve and the anchor rod can be inserted into the clamping frame 23 and the fixing frame 24 by the feeding and discharging mechanism 4. During the insertion process, the distance between the two clamping frames 23 gradually decreases under the driving of the pushing frame 22, and the large contact area between the nut, the gasket and the rotating disc 11 and the clamping frame 23 makes it difficult for them to slip out. Then, when the sleeve and the anchor rod are placed, the clamping frame 23 has been reduced to a small distance to gradually clamp the nut and the gasket, and preferably the anchor rod is inserted when the distance between the two clamping frames 23 is smallest, so that the anchor rod can be aligned with the center of the nut. At this time, the pressing mechanism 25 is in a compressed state, and then the rotating disc 11 continues to rotate to tighten the anchor rod. At this time, the distance between the two clamping frames 23 gradually increases, but the anchor rod can still be tightened by rotating downward by the extrusion of the nut by the pressing mechanism 25. When the rotating disc 11 continues to rotate and the extrusion force of the pressing mechanism 25 on the nut is weak, the anchor rod has been driven to rotate downward by a certain distance. Then, even if the nut shakes, the anchor rod can still continue to rotate downward, so as to reduce the friction between the nut and the original arc-shaped limiting plate.In order to elastically rotate the anchor rod downward, avoid forced pressing downward rotation to cause thread wear, after the feeding is completed, the fixed frame 24 continues to be driven to rotate by the rotating disc 11, so that the top end of the fixed frame 24 can abut against a plurality of pressing grooves 36 on the pressing frame 35, thereby driving the lifting frame 32 to be elastic by the elastic mechanism 34, the pressing grooves 36 drive the lifting frame 32 to descend, so that the lifting frame 32 slides up and down on the fixed frame 24, when the lifting frame 32 rises or descends, the telescopic clamping column 33 on the lifting frame 32 can slide in the driving groove 31 on the fixed frame 24, and the lifting frame 32 is driven to rotate around the fixed frame 24 by the fluctuation curve of the driving groove 31 and the telescopic clamping column 33, and the telescopic clamping column 33 is automatically popped out at the bending part of the driving groove 31 and clamped at the next step, so that the telescopic clamping column 33 can only continue to slide along the driving groove 31 and cannot slide back when it is driven to move again, thereby avoiding thread wear caused by forced downward rotation of the mechanical hand and reducing production cost through continuous downward pressing and rotating of the lifting frame 32 and elastic extrusion of the anchor rod by the elastic pad 37 thereon; more clamping frames 23 can be installed on the rotating disc 11 by increasing the diameter of the rotating disc 11, and the length of the pressing frame 35 can be increased, so that the anchor rod can be rotated downward to different depths, and a through hole can be arranged below the nut after the nut is clamped, so as to facilitate the anchor rod to be rotated out; the driving groove 31 can be a continuous wave line type, a continuous V line type and the like.

[0064] In an embodiment, please refer to Figures 2 to 5 , the arc length between the adjacent highest point and the lowest point in the pressing groove 36 is greater than or equal to the arc length between the adjacent highest point and the lowest point in the driving groove 31, and the vertical distance between the adjacent highest point and the lowest point in the pressing groove 36 is greater than or equal to the vertical distance between the adjacent highest point and the lowest point in the driving groove 31.

[0065] By adopting the above technical scheme, when the condition is equal, the lifting frame 32 always abuts against the pressing groove 36, and when the adjacent highest point on the pressing groove 36 slides to the lowest point, the telescopic clamping column 33 driven to rotate thereon can exactly slide from the adjacent highest point to the lowest point on the pressing groove 36, so that the lifting frame 32 is not pressed completely, and the telescopic clamping column 33 cannot drive the lifting frame 32 to rotate back; when the condition is greater, the lifting frame 32 does not abut against the top end of the pressing groove 36, that is, the lifting frame 32 only abuts against the two sides of the pressing groove 36, and when the lifting frame 32 slides along one side wall of the pressing groove 36 to the bottom end, the lifting frame 32 can be completely pressed down, so that the lifting frame 32 can be completely pressed down, and the telescopic clamping column 33 can be clamped into the next step of the driving groove 31.

[0066] In an embodiment, please refer to Figure 3The lifting frame 32 is arc-shaped and has a circumference greater than that of a half concentric circle, so that at least two telescopic clamping columns 33 are located in the driving groove 31 during rotation of the lifting frame 32.

[0067] By adopting the above technical scheme, the fixed frame 24 and the lifting frame 32 are concentrically arc-shaped, the arc length of the lifting frame 32 is greater than the circumference of a half concentric circle, that is, the lifting frame 32 is always abutted by a part of the fixed frame 24, thereby avoiding falling off of the lifting frame 32, and the lifting frame 32 can be a complete ring, the nut and the gasket are inserted at the bottom, the sleeve and the anchor rod are dropped from the top, so that the lifting frame 32 can be bounced up after the anchor rod is tightened, and a space for pushing out of the assembled anchor bolt is left; when the lifting frame 32 is arc-shaped, at least two telescopic clamping columns 33 are located in the driving groove 31, thereby limiting the lifting frame 32, and also avoiding falling off of the lifting frame 32.

[0068] In an embodiment, please refer to Figure 2 The rack 1 further comprises a rotary driving device 12, a gear 13 and an annular gear ring 14, the rotary driving device 12 is installed on the rack 1, the output end of the rotary driving device 12 is provided with the gear 13, and the annular gear ring 14 is installed on the rotating disc 11, and the gear 13 and the annular gear ring 14 are in meshing connection.

[0069] By adopting the above technical scheme, the rotary driving device 12 is preferably a stepping motor, so that the gear 13 is driven to rotate by the rotary driving device 12, the gear 13 is in meshing connection with the annular gear ring 14 on the rotating disc 11, so that the rotating disc 11 can be driven to rotate by the rotary driving device 12, and different transmission ratios of the gear 13 and the annular gear ring 14 enable the rotating disc 11 to stop at a suitable position for feeding and discharging and then rotate.

[0070] In an embodiment, please refer to Figure 4 The eccentric frame 21 is provided with an annular groove 211, and the pushing frame 22 is rotatably provided with a roller shaft 212, which is in rotational connection with the annular groove 211.

[0071] By adopting the above technical scheme, the roller shaft 212 is clamped in the annular groove 211 of the eccentric frame 21 and is in rotational connection therewith, thereby achieving the sliding connection between the eccentric frame 21 and the pushing frame 22.

[0079] By adopting the technical scheme, the two symmetrical V-shaped frames 234 and the extruding mechanism 25 installed on the fixed frame 24 can extrude the nut in three directions, so that the nut can be fixed firmly.

[0080] In an embodiment, referring to Figure 10 The telescopic clamping column 33 is slidably clamped in the lifting frame 32, and the spring 321 is installed in the lifting frame 32 and connected to the telescopic clamping column 33.

[0081] By adopting the technical scheme, the telescopic clamping column 33 is slidably clamped in the lifting frame 32 and extruded by the spring 321, so that the telescopic clamping column 33 is elastic and can be popped out and clamped into the next step when sliding in the driving groove 31.

[0082] In an embodiment, referring to Figure 10 The elastic mechanism 34 includes a plurality of abutting shafts 341 and springs 342, the abutting shaft 341 is slidably clamped in the lifting frame 32, the output end of the abutting shaft 341 abuts against the fixed frame 24, and the output end of the spring 342 is connected to the abutting shaft 341.

[0083] By adopting the technical scheme, the abutting shaft 341 is slidably clamped in the lifting frame 32 and extruded by the spring 342, and the output end of the abutting shaft 341 abuts against the fixed frame 24, so that the lifting frame 32 can be lifted by the spring 342 after being pressed down.

[0084] In an embodiment, the abutting shaft 341 is provided with a chamfer on one side in the forward rotation direction.

[0085] By adopting the technical scheme, when the abutting shaft 341 is not in abutment with the fixed frame 24, the lifting frame 32 is rotated to abut against the fixed frame 24 again, and the abutting shaft 341 can smoothly slide into the top of the fixed frame 24 through the chamfer.

[0086] In an embodiment, the elastic pad 37 is a smooth soft pad, and the elastic pad 37 is provided with a chamfer on both upper and lower ends.

[0087] By adopting the technical scheme, the sleeve can fall between the elastic pads 37, and the anchor rod can also fall through the smooth surface and the chamfer of the elastic pad 37 when falling by its own gravity, and then the chamfer on the lower side of the elastic pad 37 elastically extrudes the anchor rod to drive it to rotate downward. The chamfer can prevent the anchor rod from being lifted by the elastic pad when the elastic pad 37 is lifted. The length of the elastic pad 37 is adapted to the length of the lifting frame 32.

[0088] In an embodiment, the feeding and discharging mechanism 4 comprises two vibrating discharging plates 41, which are arranged on one side of the rotating disc 11 and are used to place nuts and washers respectively, and a mechanical arm. The discharging outlets of the vibrating discharging plates 41 are directed towards the fixed frame 24. In the rotating direction of the rotating disc 11, the vibrating discharging plate 41 for placing nuts is first passed, and then the vibrating discharging plate 41 for placing washers is passed. After the rotating disc 11 passes the vibrating discharging plates 41, the mechanical arm places sleeves and anchor rods into the fixed frame 24 from above the fixed frame 24 and the clamping frame 23 in sequence.

[0089] By adopting the above technical solution, the feeding is facilitated. When the rotating disc 11 drives the fixed frame 24 to rotate to the vibrating discharging plates 41, the vibrating discharging plates 41 generate vibration and push the nuts and washers into the fixed frame 24 and the clamping frame 23. Then, the mechanical arm places the sleeves and anchor rods into the fixed frame 24 and the clamping frame 23 from above the fixed frame 24 and the clamping frame 23 in sequence. Thus, the assembly of the expansion anchor is completed after the anchor rod is rotated downward.

[0090] In an embodiment, the feeding and discharging mechanism 4 further comprises an ejection cylinder 42, which is installed on the eccentric frame 21. The fixed frame 24 is provided with an ejection groove 43 through which the ejection cylinder 42 extends and retracts. The fixed frame 24 passes the ejection cylinder 42 after passing the pressing frame 35.

[0091] By adopting the above technical solution, the discharging of the assembled expansion anchor is facilitated. After the expansion anchor is rotated by the pressing frame 35, the rotating disc 11 drives the fixed frame 24 to rotate to the ejection cylinder 42 and stop. At this time, the ejection cylinder 42 extends from the ejection groove 43 to eject the assembled expansion anchor. The center of the pushing frame 22 is provided with an opening through which the ejection cylinder 42 extends. Thus, the ejection cylinder 42 is prevented from colliding with the pushing frame 22 when the ejection cylinder 42 ejects the expansion anchor.

[0092] In an embodiment, please refer to Figure 6 The fixed frame 24 is provided with an arc-shaped clamping plate 241, which cooperates with the arc-shaped block 235 to clamp and fix the sleeve.

[0093] By adopting the above technical solution, the sleeve is squeezed by the arc-shaped clamping plate 241 and the arc-shaped block 235. However, the fixed frame 24 with a larger diameter above the arc-shaped clamping plate 241 does not affect the descent of the anchor rod.
