Description

Technical Field

[0001] The invention relates to the technical field of automobile metal parts press-fitting equipment, and in particular to a press-fitting device for a metal bracket of an automobile rearview mirror. Background Art

[0002] In the current automotive aftermarket, rearview mirrors are easily damaged and frequently replaced parts. Mainstream rearview mirrors are fixed to the inside of the door with stud screws. When replacing rearview mirrors after sales, the door needs to be disassembled first, which results in a long after-sales time and reduced efficiency.

[0003] In order to solve the above problems, the rearview mirror improvement plan is as follows Figure 1 and Figure 2 An electromagnetic module S1 is arranged on the vehicle door, and two extendable metal connectors S3 are arranged on the metal bracket S2 of the rearview mirror. Magnets S4 are respectively pressed into the mounting grooves S6 of the two metal connectors S3. When the rearview mirror approaches the position of the electromagnetic module S1 on the vehicle door S5, the magnets S4 on the two metal connectors S3 drive the metal connector S3 to extend from the metal bracket S2 of the rearview mirror into the electromagnetic module S1. The installation of the rearview mirror is achieved by the clamping of the two metal connectors S3 and the electromagnetic module S1 and the magnetic adsorption of the magnets S4 and the electromagnetic module S1, with high efficiency.

[0004] During the production process, each rearview mirror metal bracket S2 needs to be press-fitted with two magnets S. Since the two magnets S4 are located at different positions on the rearview mirror metal bracket S2, they need to be press-fitted separately, which is inefficient. Summary of the invention

[0071] See also Figures 1 to 11 The present embodiment provides a press-fitting device for a metal bracket of a vehicle rearview mirror, including a frame 10, a fixing device, a press-fitting sleeve 20, a feed sleeve 30, a guide column 40, two press-fitting columns 50 and a driving device 60.

[0072] A fixing device (not shown) is provided on the frame 10, and is used to fix the metal bracket of the rearview mirror. The fixing device adopts the tooling of the prior art to fix the metal bracket of the rearview mirror, and its specific structure can be two upper and lower clamping members that can approach each other, and the two clamping members are respectively matched with the upper and lower sides of the metal bracket of the rearview mirror to achieve clamping and fixing.

[0073] The press-fitting sleeve 20 is transversely arranged on the frame 10, and one end of the press-fitting sleeve 20 is opposite to the two metal connectors on the rearview mirror metal bracket. A feed inlet 21 is provided at the upper end of the press-fitting sleeve 20. The feed inlet 21 is provided at the upper end side wall of the press-fitting sleeve 20.

[0074] The feed sleeve 30 is arranged vertically, and the lower end of the feed sleeve 30 is connected to the upper end of the press-fitting sleeve 20, and the inner cavity of the feed sleeve 30 is connected to the feed port 21. The feed sleeve 30 is used to place multiple magnets vertically. Specifically, in order to facilitate press-fitting, the outer circle of one end of the magnet facing the metal connector is an arc transition, which is convenient for the end of the magnet to enter the installation groove of the metal connector. In addition, in order to ensure that the magnet falls vertically in the feed sleeve 30, both ends of the magnet are flat and fit with the inner walls of both sides of the feed sleeve 30. The magnet is generally a rectangular structure, so the cross-section of the feed port 21 is rectangular, and the cross-section of the inner cavity of the feed sleeve 30 is also rectangular, and multiple magnets are stacked in the feed sleeve 30. In the inner cavity of the feed sleeve 30, there is only one magnet at the same height. The setting of the feeding sleeve 30 limits the feeding method of the magnets. Workers only need to put the magnets in from the top of the feeding sleeve 30, and the magnets can be fed by gravity, which is more convenient.

[0075] The guide column 40 is coaxially rotatably arranged in the press-fitting sleeve 20, and guide grooves 41 extending axially and open at both ends are respectively provided on the outer walls of the two opposite sides of the guide column 40. Specifically, one or more annular grooves are provided on the inner wall of the press-fitting sleeve 20, and a protrusion is correspondingly provided on the outer wall of the guide column 40. The protrusion can slide in the annular groove, so that the guide column 40 can rotate in the press-fitting sleeve 20.

[0076] The guide groove 41 can receive the magnet dropped from the feed port 21. The ends of the two guide grooves 41 correspond to the mounting grooves on the two metal connectors respectively, and the width of the guide groove 41 matches the width of the magnet, so that the magnet is just located in the guide groove 41 when it drops from the feed port 21, and the magnet does not shake. In addition, the mouth of the guide groove 41 can be set as an inclined surface to guide the magnet when it drops from the feed port 21. The guide groove 41 and the inner wall of the press-fitting sleeve 20 form a positioning channel, the size of which limits the magnet to slide only along the length direction of the guide groove 41.

[0077] The two press-fitting posts 50 are respectively slidably disposed in the corresponding guide grooves 41, and can push the magnet in the guide groove 41 to move toward the corresponding metal connector, so that the magnet enters the installation groove of the metal connector to complete the press-fitting. The driving device 60 is used to drive the two press-fitting posts 50 to slide in the guide grooves 41, and the driving device 60 is also used to drive the two press-fitting posts 50 to drive the guide post 40 to rotate.

[0078] In this embodiment, a worker places a plurality of magnets in the feed sleeve 30, and the stacked magnets fall from the feed port 21 into the press-fitting sleeve 20, onto the guide groove 41 of the guide column 40. As the driving device 60 drives the press-fitting column 50 to drive the guide column 40 to rotate, the guide groove 41 on the other side of the guide column 40 also rotates to below the feed port 21, and the magnet falls into the guide groove 41. When both guide grooves 41 are loaded with magnets, the driving device 60 drives the two press-fitting columns 50 to slide along the guide groove 41, and the press-fitting columns 50 push the magnets to be inserted into the mounting groove of the metal connector to achieve the press-fitting of the magnets. That is, under the drive of the driving device 60, the press-fitting column 50 drives the guide column 40 to rotate once to feed two magnets, and the press-fitting column 50 can simultaneously push the two magnets to achieve the press-fitting of the two metal connectors and the two magnets, thereby improving efficiency.

[0079] In one embodiment, the driving device 60 includes a hydraulic cylinder 62 , a driving rod 63 and a connecting sleeve 65 .

[0080] The hydraulic cylinder 62 is arranged on the frame 10. One end of the driving rod 63 is connected to the output end of the hydraulic cylinder 62, and the other end of the driving rod 63 is connected to the limiting column 64. One end of the connecting sleeve 65 is closed and connected to the two press-fitting columns 50, and the other end portion of the connecting sleeve 65 is provided with a limiting ring 66 that shrinks inward. The driving rod 63 is inserted into the connecting sleeve 65. The outer wall of the limiting column 64 is gap-matched with the inner wall of the connecting sleeve 65, and the outer wall of the driving rod 63 is gap-matched with the inner ring of the limiting ring 66. The limiting column 64 can be abutted against the limiting ring 66. The driving rod 63 is also connected to the linkage mechanism 61, and the reciprocating movement of the driving rod 63 can drive the connecting sleeve 65 to rotate through the linkage mechanism 61.

[0081] In this embodiment, the hydraulic cylinder 62 drives the connecting sleeve 65 to move back and forth through the driving rod 63, thereby realizing the reciprocating movement of the press-fitting column 50, thereby realizing the press-fitting of the magnet and the metal connecting piece. During the reciprocating movement of the driving rod 63, the driving rod 63 can drive the connecting sleeve 65 to rotate, thereby realizing that the magnet enters the two guide grooves 41 respectively.

[0082] In one embodiment, the linkage mechanism 61 includes a support plate 70 , a rotating column 71 , a first bevel gear 72 , a second bevel gear 74 and a linkage assembly 75 .

[0083] The support plate 70 is slidably arranged on the frame 10 and connected to the driving rod 63. A penetrating mounting circular hole 701 is provided on the support plate 70. A strip hole 702 with a semicircular length centered on the axis of the mounting circular hole 701 is also provided on the support plate 70. Specifically, the strip hole 702 is in the shape of a fan ring when viewed from the end face of the support plate 70, and the fan ring is half of a circular ring. Guide blocks are connected to both sides of the support plate 70. A protrusion is connected to the end of the guide block. A slide groove is provided at the corresponding protrusion on the frame 10. The protrusion and the slide groove are slidably matched. The guide block can also be slidably connected to the frame 10 by means of a guide rail.

[0084] The rotating post 71 is rotatably disposed in the mounting circular hole 701 .

[0085] The first bevel gear 72 is coaxially connected to the rotating column 71, and a latch 73 is connected to one end of the first bevel gear 72 facing the support plate 70, and the latch 73 is clearance-matched with the strip hole 702. Specifically, when the latch 73 rotates with the first bevel gear 72, the latch 73 moves in the strip hole 702. Due to the length limitation of the strip hole 702, the first bevel gear 72 can only reciprocate within 180 degrees. The first bevel gear 72 is located above the support plate 70.

[0086] The second bevel gear 74 is sleeved outside the connecting sleeve 65, and the second bevel gear 74 and the connecting sleeve 65 are axially slidably matched, and the second bevel gear 74 is coaxially rotatably connected with the driving rod 63. The second bevel gear 74 meshes with the first bevel gear 72. Specifically, the outer wall of the connecting sleeve 65 is provided with a plurality of guide protrusions extending along its axial direction, and the inner ring of the second bevel gear 74 is provided with a plurality of notches penetrating along the axial direction, and the notches are slidably matched with the corresponding guide protrusions. The second bevel gear 74 is connected to a plurality of connecting blocks at one end facing the hydraulic cylinder 62, and the connecting blocks extend outside the driving rod 63. A bearing is sleeved on the outer wall of the driving rod 63, and a plurality of connecting blocks are connected to the outer ring of the bearing, so as to realize the rotation connection between the second bevel gear 74 and the driving rod 63. The linkage assembly 75 drives the first bevel gear 72 to reciprocate by 180 degrees by means of the movement of the driving rod 63 (180-degree reciprocating rotation means that the cycle is performed by rotating 180 degrees forward and then rotating 180 degrees reversely).

[0087] In this embodiment, the second bevel gear 74 and the first bevel gear 72 have the same parameters. When the first bevel gear 72 rotates 180 degrees, the second bevel gear 74 rotates 180 degrees to sequentially drive the two press-fitting columns 50 and the guide column 40 to rotate 180 degrees. Before the guide column 40 rotates, the magnet enters one of the guide grooves 41 from the feed port 21. The guide column 40 rotates 180 degrees to allow another magnet to enter the other guide groove 41 from the feed port 21.

[0088] In one embodiment, the linkage assembly 75 includes a first linkage column 751 , a second linkage column 752 , a linkage spring 753 and a transmission assembly 76 .

[0089] The first linkage column 751 is connected to the support plate 70 , and the axis of the first linkage column 751 and the axis of the first bevel gear 72 define a first surface.

[0090] The second linkage column 752 is connected to the end face of the first bevel gear 72, and the axis of the second linkage column 752 defines a second face with the axis of the first bevel gear 72. The axes of the first linkage column 751, the second linkage column 752 and the first bevel gear 72 are parallel to each other.

[0091] The two ends of the linkage spring 753 are respectively rotatably connected with the first linkage column 751 and the second linkage column 752. Specifically, an annular groove is provided at the ends of the first linkage column 751 and the second linkage column 752, and a ring is provided at the two ends of the linkage spring 753, and the ring is sleeved in the corresponding groove.

[0092] When the latch 73 moves to the middle of the strip hole 702, the first surface and the second surface are coplanar. Specifically, the linkage spring 753 is stretched to the maximum length, and the first bevel gear 72 only needs to rotate a small angle, and the linkage spring 753 can shrink and drive the first bevel gear 72 to rotate. When the latch 73 is located at the end of the strip hole 702, the first surface and the second surface are perpendicular to each other, and the linkage spring 753 is in a natural state (the spring is not under force at this time).

[0093] The transmission assembly 76 drives the first bevel gear 72 to rotate by moving the driving rod 63 , so that the latch pin 73 rotates more than 90 degrees around the axis of the first bevel gear 72 starting from one end of the bar-shaped hole 702 .

[0094] In this embodiment, Figure 5 At this time, the press rod moves forward and starts to press the magnet into the installation groove of the metal connector. When the press fitting is completed, the driving rod 63 drives the connecting sleeve 65 to withdraw. After the press rod passes through the feed port 21, the magnet in the feed port 21 falls into the guide groove 41. Then, as the driving rod 63 further withdraws, the transmission assembly 76 drives the first bevel gear 72 to rotate more than 90 degrees. Then, under the action of the linkage spring 753, the first bevel gear 72 completes a total rotation of 180 degrees. The second bevel gear 74 drives the guide column 40 to rotate 180 degrees through the connecting sleeve 65 and the press rod. The other guide groove 41 on the guide column 40 is located below the feed port 21, and the magnet falls to complete the feeding.

[0095] In one embodiment, the transmission assembly 76 includes a mounting seat 761 , a first trigger rod 762 , a second trigger rod 763 , a transmission gear 764 and a wedge block 766 .

[0096] The mounting seat 761 is connected to the lower end of the transmission column, and the mounting seat 761 and the first bevel gear 72 are respectively located on both sides of the support plate 70 .

[0097] The first trigger rod 762 is vertically slidably disposed on the mounting seat 761. A plurality of tooth grooves evenly distributed along its axial direction are provided on one side of the outer wall of the first trigger rod 762, and gear teeth are formed between two adjacent tooth grooves. The second trigger rod 763 is vertically slidably disposed on the mounting seat 761. A plurality of tooth grooves evenly distributed along its axial direction are provided on one side of the outer wall, and gear teeth are formed between two adjacent tooth grooves. The transmission gear 764 is rotatably disposed on the mounting seat 761, and its two sides are respectively meshed with the gear teeth on the upper end of the first trigger rod 762 and the gear teeth on the lower end of the second trigger rod 763. Specifically, the mounting seat 761 is provided with two vertical mounting holes, and a vertically penetrating mounting cavity is provided between the two mounting holes. The first trigger rod 762 and the second trigger rod 763 are respectively vertically disposed in the two mounting holes. The transmission gear 764 is rotatably disposed in the mounting cavity and meshes with the gear teeth on the first trigger rod 762 and the second trigger rod 763 on both sides.

[0098] The stopper 765 is disposed on the frame 10 and can abut against the lower end of the first trigger rod 762 or the lower end of the second trigger rod 763 .

[0099] The wedge block 766 is disposed on the frame 10, and its inclined surface can abut against the lower end of the first trigger rod 762 or the lower end of the second trigger rod 763. The wedge block 766 and the stopper 765 are located on both sides of the mounting seat 761. The inclined surface of the wedge block 766 faces the direction of the hydraulic cylinder 62. The wedge block 766 can be replaced by a triangular prism with a triangular cross section.

[0100] The axis of the first trigger rod 762, the axis of the second trigger rod 763 and the axis of the transmission rod are parallel to each other. The wedge block 766 is located between the stopper 765 and the press-fit sleeve 20. The axis of the first trigger rod 762, the axis of the second trigger rod 763 and the axis of the transmission column form an obtuse triangle space, and the obtuse angle is located at the axis of the transmission column.

[0101] When the latch 73 is located at one end of the strip hole 702 , the first trigger rod 762 and the second trigger rod 763 are located at one side of the driving rod 63 , and the transmission column is located between the first trigger rod 762 and the second trigger rod 763 .

[0102] In this embodiment, Figure 5 When the driving rod 63 moves to the left, the support plate 70 moves to the left, and the lower end of the first trigger rod 762 abuts against the inclined surface of the wedge block 766, so that the first trigger rod 762 moves up, and the second trigger rod 763 moves down through the transmission of the transmission gear 764.

[0103] Then the driving rod 63 moves to the right and retreats, the support rod drives the mounting seat 761 to move to the right through the transmission column, the lower end of the second trigger rod 763 abuts against the block 765, and the second trigger rod 763 will eventually rotate to the bottom of the driving rod 63. At this time, the second trigger rod 763 must rotate more than 90 degrees, so that the linkage spring 753 can drive the first bevel gear 72 to rotate, and finally drive the guide column 40 to rotate, so as to realize the magnet feeding. In this process, the first trigger rod 762 will not interfere with the block 765 after moving up. The second trigger rod 763 also rotates 180 degrees.

[0104] When the driving rod 63 moves to the left again, the second trigger rod 763 first abuts against the inclined surface of the wedge block 766, so that the second trigger rod 763 moves up and the first trigger rod 762 moves down, and then the driving rod 63 moves to the right, and the first trigger rod 762 abuts against the stop block 765, so that the first bevel gear 72 rotates 180 degrees in the opposite direction compared to the previous time.

[0105] In one embodiment, the block 765 includes a first blocking portion 767 and a second blocking portion 768 that are symmetrical to each other; the first blocking portion 767 and the second blocking portion 768 are arranged obliquely; the first blocking portion 767 and the second blocking portion 768 are respectively located on both sides of the driving rod 63; the first blocking portion 767 and the second blocking portion 768 are horn-shaped toward the mounting seat 761.

[0106] In this embodiment, when the first trigger rod 762 and the second trigger rod 763 contact the first blocking portion 767 or the second blocking portion 768, they can be guided by the first blocking portion 767 or the second blocking portion 768, so that the first trigger rod 762 or the second trigger rod 763 drives the mounting seat 761 to rotate more smoothly.
