DETAILED DESCRIPTION

[0047] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects of the present invention, the following is a detailed description in combination with the specific embodiments listed and the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention.

[0048] Embodiment: A door closer auxiliary pressure bushing device, see Figure 1-Figure 4, including: a mounting seat 11; a mounting frame 12 fixedly mounted on the rear of the mounting seat 11; a presser 13 fixedly mounted on the top of the mounting frame 12, the shell 01 and the bushing 02 are assembled below the presser 13; a crimping head 14 installed at the lower part of the presser 13, the presser 13 controls the crimping head 14 to move up and down, the size of the crimping head 14 is adapted to the bushing 02 and is against the bushing 02, so that when the crimping head 14 moves downward, the bushing 02 can be pressed into the shell 01; a shovel frame 21 slidably mounted on the front of the mounting seat 11, the shovel frame 21 moves forward and backward, the rear part of the shovel frame 21 is tilted, and when the shovel frame 21 moves backward, it will be able to be inserted between the mounting seat 11 and the shell 01, thereby transferring the shell 01 from the mounting seat 11 to the shovel frame 2 1; an elastic member a22 fixedly mounted between the shovel frame 21 and the mounting seat 11, the elastic member a22 being a tension spring; a rotating handle 23 rotatably mounted on the right part of the shovel frame 21; a contact head 24 rotatably mounted at the end of the rotating handle 23; an elastic member b25 fixedly mounted between the rotating handle 23 and the contact head 24, the elastic member b25 being a torsion spring; a control frame 26 fixedly mounted on the crimping head 14, the control frame 26 moving up and down together with the crimping head 14, the control frame 26 being able to contact with the contact head 24, and controlling the rotation of the rotating handle 23 through the contact head 24; a groove 27 is provided on the upper surface of the shovel frame 21, the groove 27 increases the friction between the shovel frame 21 and the housing 01, so that the shovel frame 21 can transfer the housing 01 more stably.

[0049] When the crimping head 14 moves down to assemble the bushing 02 and the housing 01, the control frame 26 moves down synchronously. During the process, the control frame 26 squeezes the contact head 24 to rotate downward, and the elastic member b25 is twisted. After the control frame 26 passes through the contact head 24, the contact head 24 is turned back upward by the elastic member b25. At this time, the control frame 26 moves to the bottom of the contact head 24; when the crimping head 14 completes the assembly of the bushing 02 and the housing 01, the crimping head 14 and the control frame 26 move up. At this time, the control frame 26 will drive the contact head 24 to move up, so that the rotating handle 23 rotates upward, and the rotating handle 23 rotates upward. When the movable handle 23 rotates, its lower end will move backward, and the shovel frame 21 will be moved backward to shovel the assembled combination of the shell 01 and the bushing 02. The elastic member a22 will be stretched, and the combination will be transferred to the shovel frame 21. The control frame 26 continues to move upward. After the control frame 26 and the contact head 24 reach the limit position of contact between them, the control frame 26 and the contact head 24 will be separated, so that the shovel frame 21 loses the force from the control frame 26, and the elastic member a22 can move the shovel frame 21 and the combination forward, and the rotating handle 23 rotates back under the action of gravity.

[0050] See also Figure 1 , Figure 5 and Figure 6, also includes: a rotating shaft 31 rotatably mounted in the mounting seat 11; a push-out plate 32 fixedly mounted on the rotating shaft 31, the push-out plate 32 is located in the mounting seat 11, and the push-out plate 32 is eccentrically mounted on the rotating shaft 31, and the rotation of the rotating shaft 31 will cause the push-out plate 32 to rotate out of the mounting seat 11; a ramp 33 is provided on the mounting seat 11, and the ramp 33 is located on the left side of the shovel frame 21; a convex push portion 34 fixedly mounted on the bottom of the shovel frame 21; a contact block 35 fixedly mounted on the rotating shaft 31, when the shovel frame 21 moves, the convex push portion 34 can contact the contact block 35 to control the rotation of the rotating shaft 31; an elastic member c36 fixedly mounted between the rotating shaft 31 and the mounting seat 11, and the elastic member c36 is a torsion spring.

[0051] When the shovel frame 21 moves back and forth, the convex push portion 34 will rotate the rotating shaft 31 through the contact block 35, so that the ejection plate 32 is rotated out of the mounting seat 11, and the elastic member c36 is twisted, and the ejection plate 32 will push the combination of the shell 01 and the bushing 02 on the shovel frame 21 upward, so that the combination is pushed toward the ramp 33, and the ramp 33 is guided from the device for unified collection; after the convex push portion 34 passes over the contact block 35, the elastic member c36 reverses the rotating shaft 31 and rotates the ejection plate 32 back into the mounting seat 11.

[0052] When the present device is used to assemble the bushing 02 and the shell 01, the collecting frame is first placed on the left side of the ramp 33, and then the shell 01 is placed under the crimping head 14, the bushing 02 is placed in the installation position on the shell 01, the press 13 is started, and the crimping head 14 is controlled to move downward to press the bushing 02 into the shell 01. During the process, the control frame 26 passes through the contact head 24; after the crimping head 14 completes the pressing and assembly, the crimping head 14 moves upward and returns to its position, and the control frame 26 moves the shovel frame 21 backward through the contact head 24 to transfer the assembled composition to the shovel frame 21. After the control frame 26 moves to be separated from the contact head 24, the shovel frame 21 is moved forward and returned to its position by the elastic member a22, driving the assembled composition to move forward. During the process, the convex push portion 34 controls the push plate 32 to rotate out, and the assembled composition is pushed toward the ramp 33, and the ramp 33 guides the composition into the frame to complete the unloading of the composition of the shell 01 and the bushing 02.

[0053] See also Figure 1 and Figure 7, and also includes: a loading frame 41 fixedly mounted on the mounting seat 11, the loading frame 41 is located on the left side of the press 13, and a through-hole is opened on the rightmost side of the loading frame 41, and the through-hole is located directly below the crimping head 14, and the crimping head 14 moves downward to push the bushing 02 through the loading frame 41 and assemble with the shell 01; a push plate 42 slidably mounted in the loading frame 41; an elastic member d43 fixedly mounted between the push plate 42 and the loading frame 41, the elastic member d43 is a compression spring, and the elastic member d43 pushes the bushing 02 in the direction of the through-hole of the upper loading frame 41 through the push plate 42; a magnetic block 44 fixedly mounted on the loading frame 41, the magnetic block 44 is located on the side of the through-hole, the magnetic block 44 can magnetically fix the bushing 02, and the magnetic block 44 is set to an arc shape to fit the bushing 02 and improve the fixing stability of the bushing 02.

[0054] The push plate 42 is moved to the left to add an appropriate amount of bushing 02 into the feeding frame 41, and then the push plate 42 is relaxed. The elastic member d43 pushes the push plate 42 and the bushing 02 to the right, so that all the bushings 02 are closely arranged in the feeding frame 41, and the bushing 02 on the far right is against the magnetic block 44. At this time, this bushing 02 is located at the position of the through-hole and is magnetically fixed by the magnetic block 44; subsequently, when the crimping head 14 moves downward, the bushing 02 located at the through-hole of the feeding frame 41 will be assembled with the shell 01, and after this bushing 02 is separated from the rest of the bushings 02, the next bushing 02 first presses against the crimping head 14, and after the crimping head 14 moves up and returns to its position, all the bushings 02 in the feeding frame 41 will be moved right as a whole by the distance of a bushing 02 diameter by the elastic member d43. At the same time, the bushing 02 located on the far right is fixed by the magnetic block 44 and is located above the through-hole, thereby realizing automatic feeding of the bushing 02.

[0055] See also Figure 1 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 , and also includes: a top plate 51 slidably mounted on the mounting seat 11, the top plate 51 is located behind the crimping head 14, and the top plate 51 is used to limit the position of the shell 01; a screw rod 52 threadedly mounted on the mounting frame 12, the screw rod 52 is rotatably mounted with the top plate 51, and the rotating screw 52 is used to adjust the position of the top plate 51; a positioning shaft 61 slidably mounted on the mounting seat 11, and the positioning shaft 61 is used to locate the position of the shell 01 placed on the mounting seat 11; an elastic member e62 fixedly mounted between the mounting seat 11 and the positioning shaft 61, and the elastic member e62 is a compression spring; a hook plate 71 rotatably mounted on the rear end of the shovel frame 21, and the hook plate 71 is used to limit the position of the shell 01 on the shovel frame 21; an elastic member f72 fixedly mounted between the hook plate 71 and the shovel frame 21, and the elastic member f72 is a torsion spring.

[0056] When the shovel frame 21 moves backward and shovels into between the shell 01 and the mounting seat 11, the friction force generated between the shovel frame 21 and the shell 01 will cause the shell 01 to move backward. Therefore, by adding a top plate 51 to limit the movement of the shell 01, the shell 01 can be more fully transferred to the shovel frame 21, so that when the shovel frame 21 moves the shell 01 forward, the shell 01 is not easy to be separated from the shovel frame 21, and the position of the shell 01 on the shovel frame 21 is prevented from being greatly deviated, so as to prevent the ejection plate 32 from being unable to effectively eject the shell 01.

[0057] The positioning shaft 61 can quickly determine the position of the housing 01 on the mounting seat 11 by positioning the mounting hole of the bushing 02 on the housing 01, so as to achieve accurate loading of the housing 01 and facilitate the subsequent assembly work with the bushing 02. When the housing 01 is transferred by the shovel frame 21, the positioning shaft 61 will be squeezed by the housing 01 and retracted into the mounting seat 11. Then, after the housing 01 leaves, the elastic member e62 resets the positioning shaft 61, thereby preventing the transfer of the housing 01 from being affected.

[0058] When the shovel frame 21 moves backward and shovels into between the shell 01 and the mounting seat 11, the hook plate 71 is first squeezed by the shell 01, the hook plate 71 is rotated and retracted into the shovel frame 21, and the elastic member f72 is twisted. When the shell 01 is completely transferred to the shovel frame 21 and disengaged from the hook plate 71, the hook plate 71 is rotated back to its original position by the elastic member f72 and blocked at the rear side of the shell 01. The hook plate 71 can then limit the position of the shell 01 on the shovel frame 21, thereby improving the stability of the shovel frame 21 when moving the shell 01 and further reducing the possibility of the shell 01 being detached from the shovel frame 21.

[0059] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
