[0008] By adopting the above technical scheme, the nut feeding mechanism puts the nut into the seating groove in the nut seating seat, and then the transmission drive component drives the transmission disk to rotate intermittently to reach the O-ring feeding mechanism, then the O-ring feeding component provides the O-ring, the sleeve assembly sleeves the O-ring onto the screw of the nut, and then the transmission drive component drives the transmission disk to rotate intermittently to reach the nut unloading mechanism, and the nut unloading mechanism completes the unloading of the nut sleeved with the O-ring. In this process, the loading and unloading and sleeve processes are all completed mechanically, which effectively improves work efficiency.

[0009] Optionally, the sleeve assembly includes an O-ring intermediate support component and an O-ring sleeve assembly component; the O-ring intermediate support component is located between the O-ring feeding component and the conveying disk; the O-ring sleeve assembly component is used to sleeve the O-ring on the O-ring intermediate support component and transfer it from the O-ring intermediate support component to the nut on the conveying disk.

[0010] By adopting the above technical solution, the O-ring sleeve component sleeves the O-ring on the O-ring middle support component, and then sleeves the nut from the O-ring middle support component, which is beneficial to improving the quality of the O-ring sleeve.

[0011] Optionally, the O-ring intermediate support component includes an intermediate bracket and an O-ring intermediate support arranged on the intermediate bracket; the O-ring intermediate support includes a cylindrical intermediate support column and a truncated cone-shaped intermediate support platform coaxially fixed on the upper end surface of the intermediate support column, which is wider at the top and narrower at the bottom; a cylindrical groove-shaped intermediate avoidance groove is formed on the upper end surface of the intermediate support platform; the lower end of the intermediate avoidance groove extends to the intermediate support column; a plurality of radial avoidance grooves with radial openings evenly distributed around the circumference are formed on the cylindrical surface of the intermediate avoidance groove; the upper end of the radial avoidance groove is opened; the O-ring sleeve component includes a sleeve vertical support frame, a sleeve horizontal moving frame horizontally arranged on the sleeve vertical support frame, a sleeve horizontal driving member for driving the sleeve horizontal moving frame, and a sleeve horizontal driving member vertically arranged on the sleeve horizontal moving frame. A sleeve vertical moving frame on the frame, a sleeve vertical driving member for driving the sleeve vertical moving frame to vertically lift and lower, a sleeve claw cylinder arranged on the sleeve vertical moving frame and an O-ring sleeve member arranged on the sleeve vertical moving frame; a pair of claws of the sleeve claw cylinder cooperate with the radial avoidance groove; the O-ring sleeve member includes an O-ring grasping member and a grasping and releasing driving member arranged on the sleeve vertical moving frame; the O-ring grasping member includes an annular cylindrical O-ring grasping sleeve, a plurality of O-ring claws radially movable in the O-ring grasping sleeve and an opening and closing driving frame vertically movable in the O-ring grasping sleeve and driving all the O-ring claws to move away or approach synchronously; the O-ring claws correspond to the radial avoidance groove one by one; the grasping and releasing driving member is used to drive the opening and closing driving frame to move vertically.

[0012] By adopting the above technical scheme, a pair of claws of the sleeve claw cylinder grab the O-ring, and then the sleeve vertical moving frame rises under the action of the sleeve vertical driving member, and then moves horizontally to above the middle support of the O-ring under the action of the sleeve horizontal driving member, and then the sleeve vertical moving frame descends under the action of the sleeve vertical driving member, and the O-ring is sleeved on the middle support table, and then the pair of claws of the sleeve claw cylinder release the O-ring, and then the sleeve vertical moving frame rises and returns to its position under the action of the sleeve vertical driving member, and then the sleeve claw cylinder moves horizontally back to its position under the action of the sleeve horizontal driving member, at this time the O-ring grabbing member reaches above the middle support of the O-ring, and then the sleeve vertical moving frame descends under the action of the sleeve vertical driving member, and at this time the O-ring claws are inserted into the radial avoidance groove from top to bottom and enter the O Then, the grab and release driving part drives the opening and closing driving frame to descend vertically, and in this process, all the O-ring claws are driven to move radially outward synchronously, so that the O-ring becomes larger, and then the vertical moving frame is raised and returned to its position under the action of the vertical driving part, thereby driving the O-ring to move up, and then, under the action of the horizontal driving part, it moves horizontally to just above the nut in the placement groove, and then, under the action of the vertical driving part, the vertical moving frame is lowered so that the O-ring is vertically sleeved on the screw of the nut from top to bottom, and then the grab and release driving part drives the opening and closing driving frame to descend vertically, driving some O-ring claws to move radially inward synchronously, and at the same time, the descending opening and closing driving frame drives the O-ring to disengage from the O-ring claws, so that it is sleeved on the screw of the nut, thus realizing the automatic sleeve of the O-ring, thereby improving production efficiency.

[0013] Optionally, the opening and closing drive frame includes a circular plate-shaped opening and closing intermediate block and a plurality of fan-ring-shaped opening and closing drive blocks fixed on the cylindrical surface of the opening and closing intermediate block; the opening and closing drive blocks are evenly distributed around the circumference and a radial moving groove for radial movement of the O-ring claw is provided between a pair of adjacent opening and closing drive blocks; a cylindrical swinging drive column is horizontally penetrated and fixed on the upper part of the O-ring claw; a pair of vertical side walls of the radial moving groove are respectively formed with driving sliding grooves for the end of the swinging drive column to slide; the driving sliding groove is composed of an arc-shaped swinging part at the lower part and a vertically arranged vertical moving avoidance part at the upper end; the rotation center of the swinging part is located on its inner side.

[0014] By adopting the above technical solution, the descending opening and closing driving frame drives the O-ring claw to move radially and horizontally due to the cooperation between the swing driving column and the driving sliding groove, thereby realizing the opening and closing of the O-ring, which has a simple structure and is easy to operate.

[0015] Optionally, a plurality of groups of guide members are formed on the inner cylindrical surface of the O-ring grabbing sleeve; the guide members correspond one-to-one to the radial moving grooves and include at least two radial guide pillars distributed up and down; the upper part of the O-ring claw is radially sleeved on all the radial guide pillars of the same group of guide members.

[0016] By adopting the above technical solution, the guiding effect of the radial guide column makes the movement of the O-ring claw more stable.

[0017] Optionally, a coaxially arranged fan-ring-shaped vertical avoidance groove is formed at the lower portion of the inner cylindrical surface of the opening and closing drive block; both ends of the circumference of the vertical avoidance groove are open and its outer diameter is larger than the outer diameter of the screw.

[0018] By adopting the above technical solution, the existence of the vertical avoidance groove prevents the opening and closing drive frame from colliding with the screw when descending, which is conducive to the O-ring being disengaged from the O-ring claw.

[0019] Optionally, the O-ring feeding assembly includes an O-ring feeding seat; the O-ring feeding seat includes a feeding and discharging seat; the feeding and discharging seat is inclined and one end close to the O-ring middle support component is lower than the end away from the O-ring middle support component; a sliding storage trough for the sliding of the O-ring is formed on the upper end surface of the feeding and discharging seat; the width of the sliding storage trough is equal to the outer diameter of the O-ring and the height is equal to the thickness of the O-ring; a feeding cover is fixed on the feeding and discharging seat; the feeding cover covers the upper end opening of the sliding storage trough; a gap for the vertical entry and exit of the O-ring is provided between the end surface of the feeding cover close to the O-ring middle support component and the side wall of the sliding storage trough close to the O-ring middle support component; a grabbing avoidance groove cooperating with a pair of claws of the sleeve claw cylinder is formed in the middle part of the side wall of the sliding storage trough close to the O-ring middle support component.

[0020] By adopting the above technical scheme, the cooperation between the feeding cover plate and the sliding storage trough allows the O-ring to descend smoothly along the inclined feeding and discharging seat without accidentally falling out. At the same time, when grabbing the O-ring, one claw of the sleeve claw cylinder enters into the O-ring, and the other claw is located outside the O-ring and facing the grabbing avoidance groove, and then a pair of claws of the sleeve claw cylinder are close to clamp the O-ring, and then the sleeve claw cylinder rises to drive the O-ring out from the gap between the end face of the feeding cover plate close to the middle support component of the O-ring and the side wall of the sliding storage trough close to the middle support component of the O-ring, which facilitates the loading and grabbing of the O-ring.

[0021] Optionally, a detection mechanism is provided between the O-ring feeding mechanism and the nut unloading mechanism; the detection mechanism is used to detect whether an O-ring is sleeved on the nut.

[0022] By adopting the above technical solution, the existence of the detection mechanism reduces the possibility of missing the O-ring.

[0023] Optionally, an oiling mechanism is arranged between the O-ring feeding mechanism and the nut unloading mechanism; the oiling mechanism comprises an oiling rack, an upper pressure assembly arranged on the oiling rack and an oiling assembly arranged on the oiling rack; the upper pressure assembly comprises an upper pressure plate arranged vertically on the upper side of the conveying disc and an upper pressure driving member for driving the upper pressure plate; the oiling assembly comprises an oiling lifting plate arranged vertically on the lower side of the conveying disc, an oiling driving member for driving the oiling lifting plate and an oiling pipe vertically penetrated and fixed on the oiling lifting plate; the oiling pipe is connected to a lubricating oil feeding device; a downwardly opening upper oiling through-hole is formed on the lower side wall of the accommodating groove; a plurality of upper and lower oiling through-holes are formed on the conveying disc; the upper oiling through-holes and the lower oiling through-holes correspond one to another in upper and lower directions and are used for the oiling pipe to pass through from bottom to top.

[0024] By adopting the above technical scheme, when oiling, the upper pressure plate descends to press the nut, and then the oiling lifting plate rises so that the oiling tube passes through the lower oiling perforation and the upper oiling perforation from top to bottom and enters the lower part of the nut, and then the lubricating oil feeding device supplies oil to the oiling tube, and the oil output from the oiling tube is used to oil the nut, so that the oiling is completed at the same time during the O-ring assembly process, reducing the subsequent additional oiling process, saving time and effort.

[0025] Optionally, the number of the seating grooves on the nut seating seat is two, and a pair of the seating grooves are symmetrically distributed along the symmetry center plane of the conveyor disk.

[0026] By adopting the above technical solution, a pair of placement grooves are provided on the nut placement seat, which can simultaneously complete the assembly of the O-rings of a pair of nuts, thereby improving the assembly efficiency.

[0027] In summary, the beneficial effects of this application are:

[0028] 1. The loading and unloading and sleeve setting processes are all completed mechanically, which effectively improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
