DETAILED DESCRIPTION

[0063] The present application will be further described below in connection with specific embodiments. It should be understood that these embodiments are only used to illustrate the present application and not used to limit the scope of the present application. In addition, it should be understood that after reading the content taught by the present application, those skilled in the art can make various changes or modifications to the present application, and these equivalent forms also fall within the scope of the appended claims of the present application.

[0064] Reference Figures 1 to 10In particular, embodiment 1 provides a press-fitting device for a throttle valve magnet assembly 402, which includes a base plate 101, a first positioning mechanism 100 on the base plate 101 for fixing a throttle valve body 400, a second positioning mechanism 300 for pre-positioning the magnet assembly 402, a pressing mechanism 200 for press-fitting the magnet assembly 402 at a mounting position of the throttle valve (the mounting position refers to a position for mounting the magnet assembly 402, such as the magnet assembly 402 being press-fitted at the top end of the throttle valve shaft 401, the pawl 403 of the magnet assembly 402 being clamped with the reset gear insert 404 to help fix the magnet assembly 402), and a control mechanism. The second positioning mechanism 300 includes a pre-assembly seat 307 for pre-positioning the magnet assembly 402, and the pre-assembly seat 307 is made of metal with a magnet-adsorbing function, such as being made of iron. The control mechanism controls the operation of the first positioning mechanism 100, the second positioning mechanism 300, and the pressing mechanism 200.

[0065] The first positioning mechanism 100 includes a first mounting plate 102, the first mounting plate 102 being provided with a first fixing plate 103 and a first fixing bracket 104 for fixing the throttle valve body 400; the first mounting plate 102 is further provided with a second fixing plate 105 connected to a first driving device 106 (such as a pneumatic cylinder), and the movable end of the first driving device 106 is provided with a first pressing block 107 for pressing the throttle valve body 400 in cooperation with the first fixing plate 103. The first pressing block 107 tightly presses one side of the throttle valve body 400 against the first fixing plate 103, and at the same time, the throttle valve body 400 is inserted into the arc-shaped fixing slot of the first fixing bracket 104. Then, the movable end of the first driving device 106, together with the first pressing block 107, moves towards the throttle valve body 400 until the first pressing block 107 presses the throttle valve body 400. At this time, the first pressing block 107 and the first fixing plate 103 press the throttle valve body 400 at both ends, thereby achieving the fixation of the throttle valve body 400. The first fixing bracket 104 is provided with an arc-shaped clamping opening 108 for fixing the throttle valve body 400, which matches the shape of the throttle valve body 400 and helps to pre-position the throttle valve body 400 before the first pressing block 107 and the first fixing plate 103 press the throttle valve body 400 at both ends. The control mechanism controls the operation of the first driving device 106.

[0066] The first mounting plate 102 is provided with a first positioning hole 109 for one end (such as the bottom end) of the throttle valve shaft 401 in the throttle valve body, which can ensure that the throttle valve shaft 401 remains in a vertical state, thereby facilitating the press-fitting of the mounting position for mounting the magnet assembly 402 at the other end (the top end of the throttle valve shaft 401) of the throttle valve in the vertical direction, and ensuring good press-fitting quality.

[0067] The third fixing plate 201 is arranged on the bottom plate 101, and the top of the third fixing plate 201 is connected with the second mounting plate 202.

[0068] The pressing mechanism 200 comprises a second driving device 203 and a pressing rod 205. The second driving device 203 (such as a pneumatic cylinder) is connected to the second mounting plate 202, and the movable end of the second driving device 203 is connected to the first connecting plate 204. The bottom of the first connecting plate 204 is provided with the pressing rod 205 for pressing the installation position of the magnet assembly 402 on the throttle body 400 for installing the magnet assembly 402. The pressing rod 205 is aligned with the magnet assembly 402 on the pre-assembly seat 307. The second driving device 203 drives the first connecting plate 204, and the pressing rod 205 and the pressure sensor 206 are lowered together until the pressing rod 205 presses on the magnet assembly 402, and the magnet assembly 402 is pressed and installed on the top end of the throttle shaft 401. The claw 403 of the magnet assembly 402 is clamped with the reset gear insert 404, and the pressing and installing operation of the magnet assembly 402 is realized. The control mechanism controls the operation of the second driving device 203.

[0069] The bottom of the first connecting plate 204 is also provided with the pressure sensor 206. The pressure sensor 206 feeds back the pressure condition of the pressing rod 205 pressing on the magnet assembly 402 to the control mechanism. The pressure sensor 206 corresponds to the third connecting plate 306. During the pressing and installing process of the magnet assembly 402 in the pre-assembly seat 307 by the pressing rod 205, the pressure sensor 206 presses on the third connecting plate 306, and at the same time detects the stress condition given by the second driving mechanism, and senses the change of the pressing force. If the pressing force suddenly increases, it means that the magnet assembly 402 is probably damaged, which facilitates the inspection and monitoring of the pressing and installing quality by the operator.

[0070] The top surface of the first connecting plate 204 is provided with a guide rod 207, and the second mounting plate 202 is provided with a guide hole 208. The guide rod 207 passes through the guide hole 208. The guide rod 207 is arranged in a vertical direction to help the first connecting plate 204 move up and down in the vertical direction, and to ensure that the pressing rod 205 is vertically pressed on the magnet assembly 402 of the pre-assembly seat, and to ensure the pressing and installing quality.

[0071] The second positioning mechanism 300 comprises a third driving device 302 and a preloading seat 307. The third fixed plate 201 is provided with a second connecting plate 301 and a vertical first sliding rail 303 on a side facing the throttle body 400. The second connecting plate 301 is connected to the third driving device 302 (such as a lead screw). The movable end of the third driving device 302 is connected to a first connecting block 305. The first connecting block 305 is slidably connected to the first sliding rail 303 through a first sliding block 304. The first connecting block 305 is connected to a third connecting plate 306. The third connecting plate 306 is provided with the preloading seat 307 corresponding to the position directly below the pressing rod 205. The preloading seat 307 is provided with a profiling through hole 308 matching the shape of the magnet assembly 402. The third driving device 302 drives the third connecting plate 306 to move up and down, adjusts the height of the third connecting plate 306, and indirectly adjusts the height of the preloading seat. Before the magnet is pressed, the preloading seat 307 is moved downward, so that the magnet assembly 402 in the preloading seat 307 is tightly attached above the top end of the throttle shaft 401, and the magnet assembly 402 is prevented from being pressed obliquely. The profiling through hole 308 is used for preloading the magnet assembly 402. The material of the preloading seat 307 can be attracted by the magnet. By using this characteristic, the magnet assembly 402 is preloaded in the profiling through hole 308, and the magnet assembly 402 is attracted in the profiling through hole 308 of the preloading seat 307 and will not fall off, achieving the preloading positioning effect. Preferably, the inner side wall of the profiling through hole 308 of the preloading seat 307 is provided with an error prevention groove 309 corresponding to the pawl 403 of the magnet assembly 402, such as three error prevention grooves 309 with different angles, which facilitates the accurate and convenient loading of the magnet assembly 402 into the profiling through hole 308 of the preloading seat 307, and improves the working efficiency and pressing quality of the magnet assembly 402 preloading operation. The error prevention grooves 309 are three, and the arc distances between adjacent error prevention grooves 309 are different (such as the first arc distance 314314, the second arc distance 315315, and the third arc distance 316316). In this way, the magnet assembly 402 can only be aligned at one angle to completely embed the three pawls 403 in the corresponding error prevention grooves 309, achieving accurate installation of the magnet assembly 402, and further improving the preloading efficiency of the magnet assembly 402 into the profiling through hole 308 of the preloading seat 307.

[0072] The outer side of the preloading seat 307 is also provided with an error prevention edge 317 to improve the installation efficiency between the preloading seat 307 and the third connecting plate 306.

[0073] The second connecting plate 301 is further provided with a first stop block 310 for limiting the first connecting block 305, the first connecting block 305 is connected with a first L-shaped support 311, and the first L-shaped support 311 is provided with a first elastic protection rod 312 corresponding to the first stop block 310; when the first connecting block 305 moves downward to the lowest position, the first connecting block 305 abuts against the first stop block 310, and before the first connecting block 305 contacts the first stop block 310, the first connecting block 305 first contacts the first elastic protection rod 312, so that the first connecting block 305 slowly falls and then abuts against the first stop block 310, thereby avoiding the impact on the first stop block 310 due to the excessive speed and force.

[0074] The first connecting block 305 is provided with a first limiting rod 313 at the top, and the first limiting rod 313 corresponds to the second mounting plate 202, thereby avoiding the first connecting block 305 from sliding off the upper part of the first sliding rail 303.

[0075] The second mounting plate 202 is further provided with a displacement sensor 209 for detecting the up-down movement position of the first connecting block 305, and the displacement sensor 209 feeds back the position condition of the up-down movement of the first connecting block 305 to the control mechanism. The displacement sensor 209 detects the up-down movement position of the first connecting block 305 in the vertical direction, which indirectly reflects the up-down movement position of the third connecting plate 306 and the pre-mounting seat 307 in the vertical direction, thereby facilitating the control mechanism to control the movable end of the third driving device 302 to stop moving downward, which can ensure that the first connecting block 305 moves downward with the third connecting plate 306, the pre-mounting seat 307 and the magnet assembly 402 to the specified position, so that the magnet assembly 402 is tightly attached to the top end of the throttle shaft 401 and is located directly above the top end of the throttle shaft 401, and meanwhile, the magnet assembly 402 will not damage the throttle shaft 401 or the reset gear insert 404, or will not be pushed out of the profiling through hole 308 of the pre-mounting seat 307. The control mechanism controls the operation of the third driving device 302.

[0076] Specific operation: first, the throttle body 400 is mounted into the first positioning mechanism 100, the first driving device 106 is controlled by the control mechanism, the first pressing block 107 and the first fixed plate 103 are used to press the throttle body 400, the throttle body 400 is fixed, then the magnet assembly 402 is pre-mounted into the profiling through hole 308 of the pre-mounting seat 307, the third driving device 302 of the second positioning mechanism 300 is controlled by the control mechanism to move downward with the third connecting plate 306, the pre-mounting seat 307 and the magnet assembly 402 to the position where the magnet assembly 402 is tightly attached to the throttle body for mounting the magnet assembly 402 and is located directly above the throttle body, the second driving device 203 is controlled by the control mechanism to move the pressing rod 205 downward until the pressing rod 205 presses the magnet assembly 402 to the top end of the throttle shaft 401, thereby completing the pressing operation between the magnet assembly 402 and the throttle body 400.

[0077] Referring to Figures 11 to 16 In this embodiment 2, in addition to the content of embodiment 1, the press-fitting device further comprises a dispensing mechanism 600 for dispensing glue on the magnet assembly 402, and a translation mechanism 500 for translating the first mounting plate 102 so that the throttle body 400 moves between the position directly below the dispensing mechanism 600 and the position directly below the press-fitting mechanism, facilitating dispensing glue on the magnet assembly 402 before press-fitting the magnet assembly 402, and facilitating bonding the magnet assembly 402 and the reset gear insert 404 by glue after press-fitting (the magnet assembly 402 and the reset gear insert 404 are connected by the pawl 403) the magnet assembly 402 and the reset gear insert 404, increasing the bonding by glue, double connection guarantee, even if the press-fitting structure between the magnet assembly 402 and the reset gear insert 404 fails (for example, the pawl 403 for connecting the magnet assembly 402 and the reset gear insert 404 fails or is damaged, resulting in the failure of the pawl 403 connection between the two), the magnet assembly 402 and the reset gear insert 404 can still be bonded together by glue, without causing the magnet assembly 402 to fall off, improving the connection safety of the two.

[0078] The control mechanism controls the operation of the translation mechanism 500 and the dispensing mechanism 600.

[0079] Specifically, the translation mechanism 500 comprises a second sliding rail 501 arranged on the bottom plate 101, a third mounting plate 502 slidably connected to the second sliding rail 501 through a second sliding block 503, and a fourth driving device 504 (such as a lead screw) arranged below the bottom plate 101. The fourth driving device 504 is connected to the bottom of the third mounting plate 502, the top of the third mounting plate 502 is connected to the bottom of a fourth connecting plate 505, and the top of the fourth connecting plate 505 is connected to the bottom of the first mounting plate 102. The fourth driving device 504 translates the third mounting plate 502, the fourth connecting plate 505, the first mounting plate 102, and the throttle body 400 thereon along the second sliding rail 501, and translates between the position directly below the press rod 205 and the position directly below the dispensing gun 611. First, the throttle body 400 is moved to the position directly below the dispensing gun 611, facilitating the dispensing gun 611 to dispense glue on the magnet assembly 402, and then the throttle body 400 is translated to the position directly below the press rod 205, facilitating the press rod 205 to press-fit the magnet assembly 402. The fourth connecting plate 505 serves as a transition plate between the first mounting plate 102 and the third mounting plate 502, facilitating the replacement of the first mounting plate 102 and the components thereon, and also helping to adjust the height of the first mounting plate 102 and the components thereon, cooperating with the pressing mechanism 200 to press-fit the magnet assembly 402 and the dispensing mechanism 600 to dispense glue on the magnet assembly 402.

[0080] The bottom plate 101 is provided with a first stop portion 506 for limiting the third mounting plate 502, a first proximity switch 507 for detecting the position of the third mounting plate 502, and a second elastic protection rod 508 corresponding to the third mounting plate 502 at one end of the second sliding rail 501. The first stop portion 506 is used to prevent the second sliding block 503 from sliding off the one end of the second sliding rail 501. The first proximity switch 507 is used to detect the position of the third mounting plate 502. Before the third mounting plate 502 contacts the first stop portion 506, it first contacts the second elastic protection rod 508, so that the third mounting plate 502 slowly moves to the first stop portion 506, avoiding the impact of the first stop portion 506 and the first proximity switch 507 due to excessive speed and force, and protecting the first proximity switch 507.

[0081] The bottom plate 101 is provided with a second stop portion 509 for limiting the third mounting plate 502, a second proximity switch 510 for detecting the position of the third mounting plate 502, and a third elastic protection rod 511 corresponding to the third mounting plate 502 at the other end of the second sliding rail 501. The second stop portion 509 is used to prevent the second sliding block 503 from sliding off the other end of the second sliding rail 501. The second proximity switch 510 is used to detect the position of the third mounting plate 502. Before the third mounting plate 502 contacts the second stop portion 509, it first contacts the third elastic protection rod 511, so that the third mounting plate 502 slowly moves to the second stop portion 509, avoiding the impact of the second stop portion 509 and the second proximity switch 510 due to excessive speed and force, and protecting the second proximity switch 510.

[0082] The first proximity switch 507 and the second proximity switch 510 feed back the position of the third mounting plate 502 to the control mechanism, which controls the operation of the fourth driving device 504.

[0083] The dispensing mechanism 600 includes a fourth fixed plate 601 connected to the bottom plate 101 at the bottom, and a fourth mounting plate 602 provided at the top of the fourth fixed plate 601. The fourth mounting plate 602 is provided with a fifth driving device 603 (such as a lead screw).

[0084] The fourth fixed plate 601 is provided with a third sliding rail 604 in the vertical direction on the side facing the throttle body 400. The movable end of the fifth driving device 603 is connected to a second connecting block 605, which is slidably connected to the third sliding rail 604 through a third sliding block 606. The second connecting block 605 is connected to a dispensing gun 611 for dispensing glue on the top end of the throttle shaft 401 of the throttle body 400 through a second fixed support 610.

[0085] When the translation mechanism 500 carries the throttle body 400 to be directly below the glue dispensing gun 611, the control mechanism controls the fifth driving device 603 to move downward along the third sliding rail 604 until the glue outlet of the glue dispensing gun 611 is opposite to the top end of the throttle shaft 401 used for pressing the magnet assembly 402, so as to facilitate the glue dispensing gun 611 to complete the glue dispensing operation on the top end of the throttle shaft 401, and after the glue dispensing, the control mechanism controls the fifth driving device 603 to move upward along the third sliding rail 604, so as to facilitate the translation mechanism 500 to carry the throttle body 400 to be below the pressing rod 205 to perform the pressing operation of the magnet assembly 402.

[0086] The fourth fixed plate 601 below the third sliding rail 604 is provided with a fifth connecting plate 607, the fifth connecting plate 607 is provided with a third stop portion 608 for limiting the second connecting block 605 and a fourth elastic protection rod 609 corresponding to the second connecting block 605; the third stop portion 608 is used to avoid the third sliding block 606 from sliding off the bottom of the third sliding rail 604. Before the third sliding block 606 slides down to the bottom and contacts the third stop portion 608, the third sliding block 606 first contacts the fourth elastic protection rod 609, so as to avoid that the third sliding block 606 slides down too fast and impacts the third stop portion 608 with too much force.

[0087] The control mechanism controls the operation of the fifth driving device 603 and the glue dispensing gun 611.
