[0037] The frame 1 is symmetrically provided with a feeding conveyor line 2 and a return conveyor line 3; a plurality of workpiece clamps 4 are installed on the feeding conveyor line 2 and the return conveyor line 3 (see the appendix of the manual). Figure 3 The workpiece clamping seat 4 is equipped with an assembly support seat 40; the workpiece clamping seat 4 on one side of the assembly support seat 40 is equipped with a positioning seat A41 and a positioning seat B42 (see the attached manual). Figure 4 During operation, the pulley to be assembled can be placed on the positioning seat A41, and the nut to be assembled can be placed on the positioning seat A41.

[0038] The ends of the feeding conveyor line 2 and the return conveyor line 3 are respectively provided with a reversing component 5 (see the appendix of the manual). Figure 3 The reversing assembly 5 includes a longitudinal slide 37, a longitudinal push cylinder 38 and an active push roller 39 (see the attached manual). Figure 5 ).

[0039] A longitudinal slide 37 is mounted on the frame 1 at one end of the feeding conveyor line 2 and the return conveyor line 3 through a guide rail; a longitudinal push cylinder 38 is mounted on the frame 1 below the longitudinal slide 37; the longitudinal push cylinder 38 can slide back and forth through the longitudinal slide 37; two sets of active push rollers 39 are symmetrically mounted on the longitudinal slide 37.

[0040] The purpose of setting up the reversing component 5 in this way is: when the workpiece clamp 4 is transported to the longitudinal slide 37 under the output of the conveyor line, the longitudinal push cylinder 38 pushes the longitudinal slide 37 to align with another set of conveyor lines, and then the active push roller 39 is activated to transport the workpiece clamp 4 to another set of conveyor lines, so that the workpiece clamp 4 can be recycled.

[0041] A set of reversing components 5 are provided at one end with a storage tray A6 and a storage tray B7; a plurality of positioning bosses 35 are evenly arranged on the storage tray A6; a plurality of positioning countersunk holes 36 are evenly arranged on the storage tray B7 (see the appendix of the manual). Figure 3 During operation, the pulley to be assembled can be placed on the positioning boss 35 , and the nut to be assembled can be placed on the positioning countersunk hole 36 .

[0042] A loading robot 8 is installed between the storage tray A6 and the storage tray B7 and the frame 1 (see the appendix of the manual). Figure 1 and 2 The loading manipulator 8 is equipped with an extraction clamp A32, an extraction clamp B33 and an extraction clamp C34 (see the attached manual). Figure 7 and 8 During operation, the loading robot 8 can grab the pulley, nut and bearing through the extraction jaws A32, B33 and C34 respectively.

[0043] Above the feeding conveyor line 2 on one side of the feeding robot 8, press-fitting assembly A9, press-fitting assembly B10 and press-fitting assembly C11 are installed in sequence (see the appendix of the manual). Figure 1 and 2 ).

[0044] The press-fitting assembly A9 and the press-fitting assembly C11 both include a bracket 14, a press-fitting cylinder 15, a press-fitting rod 16, a grabbing claw 19, a lifting cylinder 18 and a transverse slide 17; the frame 1 is provided with a press-fitting rod 16 via the bracket 14 and the press-fitting cylinder 15; the bracket 14 on the inner side of the press-fitting rod 16 is provided with a transverse slide 17 via the transverse cylinder; the transverse slide 17 is provided with a grabbing claw 19 via the lifting cylinder 18 (see the appendix of the manual). Figure 10 and 15 During operation, the grab claw 19 can grab the workpiece under the cooperation of the transverse slide 17 and the lifting cylinder 18.

[0045] The press-fitting assembly B10 includes a press-fitting cylinder 15 and a press-fitting rod 16; the frame 1 is provided with a press-fitting rod 16 via a bracket 14 and a press-fitting cylinder 15 (see the appendix of the manual). Figure 12 ).

[0046] The loading conveyor line 2 below the press-fitting assembly A9, press-fitting assembly B10 and press-fitting assembly C11 is respectively equipped with a jacking assembly (not shown in the drawings of the specification); when the jacking assembly is working, it can lift the workpiece clamp 4 to provide support.

[0047] The bearing storage assembly 12 is installed on the inner frame 1 of the press assembly A9 (see the appendix of the instruction manual). Figure 1 and 2 The bearing storage assembly 12 includes a mounting seat, a guide slide 22, a storage barrel 20 and a push plate 21 (see the appendix of the specification). Figure 11 Multiple accumulators 20 are mounted on the mounting base. A push plate 21 is attached to one side of the accumulators 20 via a push cylinder. A guide slide 22 is attached to the other side of the accumulators 20. A loading push rod 23 is attached to the guide slide 22 via a pneumatic cylinder. During operation, the push plate 21 pushes the workpiece (bearing) from the bottom of the accumulator 20 onto the guide slide 22. The loading push rod 23 then pushes the workpiece (bearing) to the loading station on the guide slide 22.

[0048] The inner frame 1 of the press assembly B10 is equipped with a positioning ring storage assembly 13 (see the attached manual). Figure 1 and 2 The positioning ring storage assembly 13 includes a dividing plate 24, a storage rod 25, a transfer truss 28, a transfer claw 29 and a lifting fork 27 (see the appendix of the specification). Figure 13 and 16 ).

[0049] The frame 1 inside the press-fitting assembly B10 is equipped with a plurality of storage rods 25 through a dividing plate 24; the frame 1 between the dividing plate 24 and the press-fitting assembly B10 is equipped with a lifting fork 27 through a lifting assembly 26 (see the appendix of the manual). Figure 16 and 17 A transfer claw 29 is mounted on the frame 1 on one side of the lifting assembly 26 via a transfer truss 28. During operation, when a set of workpieces (locating rings) on the accumulator rods 25 are used up, the lifting assembly 26 drives the lifting fork 27 to move below the indexing plate 24. The indexing plate 24 then rotates one position, causing a new accumulator rod 25 to rotate to correspond with the lifting fork 27. The lifting fork 27 then moves upward to contact the workpiece (locating ring) at the bottom end of the accumulator rod 25. After the transfer truss 28 grabs a set of workpieces (locating rings) from the top end of the accumulator rod 25 via the transfer claw 29, the lifting fork 27 can be moved upward one position to facilitate the transfer claw 29 to grab the next set of workpieces.

[0050] The upper end of the storage rod 25 is provided with two sets of guide protrusions 30; the storage rod 25 is intermittently mounted with auxiliary cones 31 through the guide protrusions 30 (see the appendix of the manual). Figure 18 When assembling the workpieces (locating rings) during operation, the auxiliary cone 31 can be inserted into the top of the corresponding storage rod 25, and then multiple workpieces (locating rings) can be manually placed from the top of the auxiliary cone 31. Then, the workpieces (locating rings) will freely fall to the bottom of the storage rod 25 under the guidance of the auxiliary cone 31 and the action of their own gravity.

[0051] During operation, the loading robot 8 first uses its extraction jaws A32 and B33 to grab the pulley and nut from the storage trays A6 and B7, respectively, and places them on the corresponding positioning seats A41 and B42 of the workpiece holder 4. The loading robot 8 then uses its extraction jaws C34 to grab a bearing from the bearing storage assembly 12 and place it on the corresponding assembly support seat 40 of the workpiece holder 4.

[0052] After the above work is completed, the loading conveyor line 2 drives the workpiece clamp 4 to move to the bottom of the press assembly A9, and then the jacking assembly lifts the workpiece clamp 4 to separate it from the loading conveyor line 2. Then, the grabbing claw 19 on the press assembly A9, in cooperation with the transverse slide 17 and the lifting cylinder 18, grabs the nut on the positioning seat B42 and places it on the bearing. Then, the press rod 16 moves to complete the press fitting of the nut and resets it.

[0053] After the nut is press-fitted, the lifting assembly resets the workpiece holder 4. The loading conveyor 2 moves the workpiece holder 4 one station to align with the press-fit assembly B10. The lifting assembly then lifts the workpiece holder 4 off the loading conveyor 2. The transfer claw 29 in the retaining ring storage assembly 13 then grabs the workpiece retaining ring and places it on the outer surface of the nut on the workpiece holder 4. The press-fitting rod 16 in the press-fitting assembly B10 then actuates to complete the retaining ring press-fitting and resets.

[0054] After the locating ring is press-fitted, the lifting assembly resets the workpiece holder 4. The loading conveyor line 2 moves the workpiece holder 4 one station to align with the press-fit assembly C11. The lifting assembly then lifts the workpiece holder 4 off the loading conveyor line 2. The gripping claw 19 in the press-fit assembly C11, working in conjunction with the transverse slide 17 and lift cylinder 18, grabs the pulley on the locating seat A41 and places it on the nut. The press-fitting rod 16 then completes the pulley press-fitting and resets.

[0055] At this point, the automobile steering gear nut assembly assembly device has completed all assembly work. After the loading conveyor line 2 drives the assembled automobile steering gear nut assembly to move to the next workstation, it is taken out through other equipment. Then the empty workpiece clamp 4 will return to the initial position from the other end to participate in the cycle with the cooperation of the loading conveyor line 2, the return conveyor line 3 and the reversing component 5.

[0056] The automobile steering gear nut assembly assembly device has a compact structure and ingenious design, and can continuously and mechanizedly complete the installation of bearings, nuts, positioning rings and pulleys, thereby solving the problem of low processing efficiency in existing automobile steering gear nut assembly methods and being particularly suitable for the needs of automobile steering gear nut assembly assembly.
