DETAILED DESCRIPTION

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3 As shown, a preferred embodiment of the swing arm press machine of the utility model includes a jig 1, a first press 2, a second press 3 and a transfer mechanism 4. The transfer mechanism 4 is a rotating table, and four jigs 1 are installed on one transfer mechanism 4, and the four jigs 1 are respectively located at the upper material position, the first press position, the second press position and the lower material position. The transfer mechanism 4 is used to drive the jig 1 to rotate, so that the jig 1 moves to different positions in sequence. The first press 2 is arranged at the first press position, and the first press machine is used to press the rubber sleeve on the lower end of the swing arm 5, and the second press 3 is arranged at the second press position, and the second press 3 is used to press the rubber sleeve on the upper end of the swing arm 5.

[0027] like Figures 4 to 6As shown, the fixture 1 includes a lifting mechanism 11, a mounting plate 12, a movable pressure block 13, a clamping mechanism 14, a first fixed seat 15, a second fixed seat 16, a third fixed seat 17 and a limiting mechanism 18. The lifting mechanism 11 is installed on the circulation mechanism 4, and the mounting plate 12 is installed on the lifting mechanism 11. The lifting mechanism 11 is used to drive the mounting plate 12 to rise and fall. The first fixed seat 15, the second fixed seat 16 and the third fixed seat 17 are all installed on the mounting plate 12. The third fixed seat 17 is arranged on both sides of the first fixed seat 15. The first fixed seat 15 is used to support the upper end of the swing arm 5, the second fixed seat 16 is used to support the lower end of the swing arm 5, and the third fixed seat 17 is used to support the end of the swing arm 5. The two third fixed seats 17 are symmetrical with the first fixed seat 15 as the center to ensure that they can adapt to the swing arm 5 on the left and the swing arm 5 on the right. The clamping mechanism 14 is used to clamp the swing arm 5 onto the first fixed seat 15, the second fixed seat 16 and the third fixed seat 17. The clamping mechanism 14 is a rotary clamping cylinder. Of course, other clamping devices can also be used. The movable pressing block 13 is slidably arranged on the mounting plate 12. The movable pressing block 13 is raised and lowered on the mounting plate 12 under the drive of the second press to press the rubber sleeve onto the swing arm 5. The limiting mechanism 18 is installed on the first fixed seat 15. The limiting mechanism 18 is used to limit the movable pressing block 13. When the limiting mechanism 18 limits the movable pressing block 13, the movable pressing block 13 cannot be pressed onto the rubber sleeve. When the limiting mechanism 18 releases the restriction on the movable pressing block 13, the movable pressing block 13 can be raised and lowered on the mounting plate 12.

[0028] The first fixed seat 15 has a movable groove 151 and a fixed notch 152. The movable pressing block 13 is raised and lowered in the movable groove 151. The fixed notch 152 is used to position the upper end of the swing arm 5. The third fixed seat 17 is provided with a positioning pin 171 to quickly position the swing arm 5 and improve the efficiency of clamping. The second fixed seat 16 includes a seat body 161, a mobile driver 162 and a positioning column 163. The mobile driver 162 is installed on the seat body 161. The positioning column 163 is fixed on the mobile driver 162. The positioning column 163 is provided with a positioning bead 164. The rubber sleeve is fixed on the positioning column 163 through the positioning bead 164. After the pressing is completed, when the positioning column 163 is pulled out from the swing arm 5, the positioning column 163 can be separated from the rubber sleeve and the rubber sleeve will not be pulled out from the swing arm 5.

[0029] like Figure 7As shown, the limit mechanism 18 includes a limit pin 181 and a limit driver 182. The limit driver 182 is mounted on the first fixed seat 15, and the limit pin 181 is mounted on the limit driver 182. The limit driver 182 is used to drive the limit pin 181 to move. The limit driver 182 can be a pneumatic cylinder or an oil cylinder, and of course, other retractable devices such as an electric lifting cylinder can also be used. A through hole is provided on the first fixed seat 15, and the limit pin 181 is placed in the through hole; when the limit pin 181 limits the movable pressure block 13, the limit pin 181 extends out of the through hole; when the limit pin 181 releases the movable pressure block 13, the limit pin 181 is completely located in the through hole, that is, the end of the limit pin 181 will not extend out of the through hole.

[0030] refer to Figures 4 to 6 The movable pressing block 13 has a pressing head 131, a first connecting block 132 and a supporting block 133. The first connecting block 132 and the movable pressing block 13 are combined to form a connecting groove 134. The connecting groove 134 is used to cooperate with the second press 3, so that the first connecting block 132 is used to connect with the second press 3, and the supporting block 133 is used to support the swing arm 5 when the swing arm 5 is placed. The rubber sleeve is sleeved on the pressing head 131, and the movable pressing block 13 presses the rubber sleeve on the swing arm 5 under the drive of the second press 3. The pressing head 131 has a positioning bead 164, and the rubber sleeve is fixed on the pressing head 131 through the positioning bead 164. At the same time, after the press-fitting is completed, the pressing head 131 can be separated from the rubber sleeve, and the rubber sleeve will not be pulled out from the swing arm 5.

[0031] The lifting mechanism 11 includes a lifting driver 111 and a lifting seat 112. The lifting driver 111 is installed on the lifting seat 112, and the lifting driver 111 is connected to the mounting plate 12. The lifting driver 111 drives the mounting plate 12 to descend, so as to send the swing arm 5 on the mounting plate 12 to a position aligned with the first press machine, so as to facilitate the press machine to press. The lifting driver 111 can be a pneumatic cylinder or an oil cylinder, and of course, other lifting devices such as an electric lifting cylinder can also be used.

[0032] When in use, first use the clamping mechanism 14 to clamp the swing arm 5 on the first fixing seat 15, the second fixing seat 16 and the third fixing seat 17 at the loading position, and then install the two sleeves on the movable pressing block 13 and the swing arm 5 respectively to complete the loading. Then, the circulation mechanism 4 rotates to drive the swing arm 5 to enter the first pressing position, and the lifting drive 111 drives the mounting plate 12 to move downward, so that the swing arm 5 is aligned with the first pressing machine, and then the first pressing machine presses the rubber sleeve on the swing arm 5. After the pressing is completed, the lifting drive 111 drives the mounting plate 12 and the swing arm 5 to reset, completing the pressing of the rubber sleeve at the lower end of the swing arm 5. Afterwards, the circulation mechanism 4 rotates again to drive the swing arm 5 into the second pressing position, the second pressing machine moves to insert the second connecting block 31 on the second press 3 into the connecting groove 134, and then the limit driver 182 drives the limit pin 181 to retract to release the restriction on the movable pressing block 13, and then the second press 3 presses the movable pressing block 13 downward to press the rubber sleeve into the swing arm 5. After completion, the mobile driver 162 drives the positioning column 163 to retract and disengage from the rubber sleeve, and the second press 3 drives the movable pressing block 13 to reset again. After resetting, the limit driver 182 drives the limit pin 181 to extend to limit the movable pressing block 13, and then the second press 3 moves to separate the second connecting block 31 from the movable pressing block 13. The circulation mechanism 4 rotates again, driving the fixture 1 to move to the unloading position, and the clamping mechanism 14 releases the swing arm 5 to remove the swing arm 5 from the fixture 1. After the swing arm 5 is removed, the mobile driver 162 drives the positioning column 163 to extend, so as to facilitate the placement of the rubber sleeve and positioning of the swing arm 5 at the same time.

[0033] The transfer mechanism 4 is used to drive the fixture 1 to move to the first press 2 and the second press 3 in sequence, and the clamping is completed at one time, thereby improving the press-fitting efficiency. At the same time, two third fixed seats 17 are arranged, so that the fixture 1 can clamp the swing arm 5 on the left side of the car and the swing arm 5 on the right side of the car, thereby improving the scope of application. Moreover, it is only necessary to apply the rubber sleeve at the same position without applying the rubber sleeve multiple times, thereby further improving the press-fitting efficiency. Four fixtures 1 are arranged, so that each workstation can have a fixture 1, thereby further improving the press-fitting efficiency.

[0034] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model.
