[0042] As shown in Figure 1 and Figure 9 An embodiment of the present application provides a manual tire mounting machine, which includes a rack 1, a rotating disc mechanism 2, a connecting frame 3, a manual displacement table 4, a shaft pressing mechanism 5, a roller pressing mechanism 6 and a rolling mechanism 7. In the manual tire mounting machine, the rack 1 serves as a mounting carrier for mounting the rotating disc mechanism 2 and the connecting frame 3.

[0043] The rotating disc mechanism 2 is rotatably connected to the rack 1, as shown in Figure 9 The rotating disc mechanism 2 is used to place the hub a and the solid tire b to be assembled, and by manually rotating the rotating disc mechanism 2, the hub a and the solid tire b are synchronously rotated.

[0044] The connecting frame 3 is movably connected with the frame 1 and can move relative to the frame 1 in a direction perpendicular to the axis of the rotating disc mechanism 2. In the present application, the connecting frame 3 can move along the length direction of the frame 1, and the length direction of the frame 1 is perpendicular to the axis of the rotating disc mechanism 2. Further, in order to limit the movement of the connecting frame 3 relative to the frame 1, a sliding groove 31 is formed on the circumferential side wall of the connecting frame 3, and a limiting structure corresponding to the sliding groove 31 can be provided on the frame 1. Figure 1 and Figure 9 As shown in the present application, the connecting frame 3 is located on the top of the frame 1, and the rotating disc mechanism 2 is located on the bottom of the frame 1. In order to avoid the manual displacement table 4 blocking the placement of the wheel hub a and the solid tire b, the connecting frame 3 is movably connected with the frame 1. When the wheel hub a and the solid tire b need to be placed on the rotating disc mechanism 2, the connecting frame 3 can be moved away from the rotating disc mechanism 2 to avoid interference with the placement of the wheel hub a and the solid tire b. After the wheel hub a and the solid tire b are placed stably, the connecting frame 3 is moved to be located directly above the rotating disc mechanism 2, so that the next tire mounting operation can be performed.

[0045] In an embodiment, in order to simplify the connection structure of the connecting frame 3 and the frame 1, the connecting frame 3 is slidably connected with the frame 1 and can move relative to the frame 1 in a direction perpendicular to the axis of the rotating disc mechanism 2. In the present application, the connecting frame 3 can move along the length direction of the frame 1, and the length direction of the frame 1 is perpendicular to the axis of the rotating disc mechanism 2. Further, in order to limit the movement of the connecting frame 3 relative to the frame 1, a sliding groove 31 is formed on the circumferential side wall of the connecting frame 3, and a limiting structure corresponding to the sliding groove 31 can be provided on the frame 1.

[0046] The manual displacement table 4 is mounted on the connecting frame 3. In the present application, the tire mounting machine is completely controlled manually. The manual displacement table 4 has an output end which can move relative to the connecting frame 3 and can move along the axis of the rotating disc mechanism 2, so as to drive the pressing wheel mechanism 6 and the rolling mechanism 7 to approach the rotating disc mechanism 2 to complete the mounting of the wheel hub a and the tire.

[0047] The pressing shaft mechanism 5 is mounted on the connecting frame 3. The pressing shaft mechanism 5 is used to limit the wheel hub a placed on the rotating disc mechanism 2. Specifically, after the wheel hub a is placed on the rotating disc mechanism 2, in order to avoid the position of the wheel hub a moving in the horizontal direction, the pressing shaft mechanism 5 is used for limiting, so as to avoid the position of the wheel hub a deviating during tire mounting.

[0048] The pressing wheel mechanism 6 is mounted on the output end of the manual displacement table 4. The pressing wheel mechanism 6 can move along the axis of the rotating disc mechanism 2 under the driving of the manual displacement table 4, and is used to press against the solid tire b. As shown in the present application, Figure 9 Before the solid tire b is pressed into the wheel hub a, one end of the solid tire b is clamped into the wheel hub a, and the other end is located outside the wheel hub a. When the end located outside the wheel hub a is pressed into the wheel hub a, the outer wall of the solid tire b needs to be pressed tightly by the pressing wheel mechanism 6.

[0049] The rolling mechanism 7 is mounted on the output end of the manual displacement table 4. As shown in the present application, Figure 10 ,Figure 11 As shown, the pressure wheel mechanism 6 can be moved along the axial direction of the rotating disc mechanism 2 under the driving of the manual displacement table 4, for pressing the solid tire b into the hub a.

[0050] It should be noted that the assembly process of the hub a and the solid tire b is as follows Figure 9 to Figure 11 As shown, the hub shaft (not shown in the figure) is located at the center of the hub a and protrudes from the two end faces of the hub a. In the present application, the rotating disc mechanism 2 and the manual displacement table 4 are both manually driven, and the present application does not involve electrical and hydraulic driving elements. The manual tire assembly operation can be realized through simple structural cooperation, which is beneficial to reducing the size and weight of the equipment. Therefore, when in use, the tire assembly machine only needs to be moved to the designated position for use, which meets the on-site rapid installation demand and reduces the production cost.

[0051] In one embodiment, as shown in the figure Figure 4 The rotating disc mechanism 2 includes a rotating disc body 21 and a driving rod 22. The rotating disc body 21 is provided with a receiving cavity 211 to avoid interference when the hub a is placed. The bottom of the receiving cavity 211 is provided with a connecting hole 212, and the machine frame 1 is provided with a rotating shaft 111 corresponding to the connecting hole 212. The outer wall of the rotating disc body 21 is circumferentially provided with a mounting hole 2131, and one end of the driving rod 22 is inserted into the mounting hole 2131. When the rotating disc body 21 is rotationally connected with the machine frame 1, the rotating shaft 111 on the machine frame 1 is inserted into the connecting hole 212 of the rotating disc body 21, so as to realize the rotational connection between the rotating disc body 21 and the machine frame 1.

[0052] In one embodiment, in order to facilitate the manual driving of the rotating disc body 21 to rotate, the rotating disc mechanism 2 is provided with the driving rod 22. In use, one end of the driving rod 22 is inserted into the mounting hole 2131, and the other end of the driving rod 22 is manually pushed to make the rotating disc body 21 rotate around the rotating shaft 111. In some embodiments, the mounting hole 2131 is a blind hole, and the driving rod 22 is in sliding connection with the mounting hole 2131, which is beneficial to the quick installation of the driving rod 22. In some other embodiments, in order to avoid the risk that the driving rod 22 slips out of the mounting hole 2131 due to the change of the position of the driving rod 22 after rotating with the rotating disc body 21 when the driving rod 22 is pushed, an internal thread is arranged on the inner wall of the mounting hole 2131, and an external thread is arranged on the outer wall of the driving rod 22, so that the driving rod 22 is in threaded connection with the mounting hole 2131.

[0053] In one embodiment, since the blind hole needs to have a certain depth, in order to reduce the overall thickness of the rotating disc body 21 and save materials, as shown in the figure Figure 4 The outer wall of the rotating disc body 21 is circumferentially provided with mounting bosses 213, and the mounting bosses 213 are provided with mounting holes 2131.

[0054] In one embodiment, in order to limit the wheel hub a after placement. Specifically, by limiting the wheel hub shaft of the wheel hub a, the overall limiting of the wheel hub a is achieved. In this application, as shown in Figure 8 The first limiting hole 2141 is used for limiting one end of the wheel hub shaft. The pressing shaft mechanism 5 includes a pressing head 51, which is in sliding connection with the connecting frame 3 and can slide along the axial direction of the turntable body 21. The end of the pressing head 51 facing the first limiting hole 2141 is provided with a second limiting hole 511, which is used for limiting one end of the wheel hub shaft. The first limiting hole 2141 on the turntable body 21 and the second limiting hole 511 on the pressing head 51 are matched to limit the wheel hub shaft. It should be noted that since the wheel hub a has a certain weight, and one end of the wheel hub shaft is inserted into the first limiting hole 2141 and the other end is inserted into the second limiting hole 511, the wheel hub a will not move in the direction of gravity, so in this application, the pressing head 51 does not need to press the wheel hub shaft. Further simplify the limiting structure of the wheel hub a, reduce the cost.

[0055] In one embodiment, the pressing head 51 is in sliding connection with the connecting frame 3. In order to facilitate the sliding of the pressing head 51 relative to the connecting frame 3, and to avoid jamming, as shown in Figure 8 The pressing head 51 adopts a cylindrical structure, and the connecting frame 3 is provided with a bearing corresponding to the pressing head 51. In order to avoid the pressing head 51 from sliding out of the bearing hole directly, the pressing shaft mechanism further includes a limiting plate 52, which is arranged at the end of the pressing head 51 away from the turntable mechanism 2. The projection area of the limiting plate 52 on the plane perpendicular to the axis of the turntable mechanism is greater than the projection area of the pressing head 51 on the plane perpendicular to the axis of the turntable mechanism. When the pressing head 51 is used to position the wheel hub a, the pressing head 51 is slid upward, and the connecting frame 3 is moved synchronously to the upper side of the wheel hub a, so that the wheel hub shaft is opposite to the second limiting hole 511. Then the pressing head 51 is loosened, and the wheel hub shaft can be inserted into the second limiting hole 511, so that the wheel hub shaft is limited by the first limiting hole 2141 and the second limiting hole 511. In addition, in order to avoid the bottom end of the pressing head 51 from coming out of the bearing hole when the pressing head 51 is slid upward, the end of the pressing head 51 close to the turntable body 21 is provided with an annular boss 512.

[0056] As shown in Figure 3 and Figure 5As shown, in order to press the solid tire b into the hub a, in an embodiment, the rolling mechanism 7 comprises a connecting arm 71 and a rolling assembly 72, one end of the connecting arm 71 is detachably connected with the output end of the manual displacement table 4, the other end of the connecting arm 71 is inclined towards the side close to the rotating disc mechanism 2; the rolling assembly 72 is connected with the end of the connecting arm 71 away from the output end of the manual displacement table 4. The manual displacement table 4 can drive the rolling mechanism 6 to move as a whole close to the rotating disc mechanism 2, so that the outer wall of the rolling assembly 72 abuts against the outer wall of the tire in the axial direction, and the solid tire b is pressed into the hub a. Since one end of the connecting arm 71 is detachably connected with the output end of the manual displacement table 4, when it is necessary to assemble different specifications of the hub a and the solid tire b, the mounting position of the connecting arm 71 and the manual displacement table 4 can be adjusted, so that the manual tire mounting machine in the present application has versatility.

[0057] As shown in Figure 2 , Figure 3 , in order to simplify the structure of the manual displacement table 4 and reduce the production cost, in an embodiment, the manual displacement table 4 comprises a first frame body 41, a driving shaft 42 and a second frame body 43. Among them, the first frame body 41 is installed on the connecting frame 3, the driving shaft 42 extends along the axial direction of the rotating disc body 21, the two ends of the driving shaft 42 are correspondingly threaded connected with the first frame body 41 and the second frame body 43, the second frame body 43 is slidingly connected with the first frame body 41, and the end of the connecting arm 71 away from the rotating disc mechanism 2 is detachably connected with the second frame body 43. In the present application, by rotating the driving shaft 42, the second frame body 43 can be driven to move along the axial direction of the driving shaft 42. In order to reduce the processing cost, the driving shaft 42 can be directly selected as a lead screw, and in order to facilitate the rotation of the driving shaft 42, a hand wheel is arranged at the end of the driving shaft 42 away from the second frame body 43, and the rotation of the hand wheel can drive the driving shaft 42 to rotate.

[0058] Further, as shown in Figure 5 , Figure 6 , in order to facilitate the adjustment of the mounting position between the connecting arm 71 and the second frame body 43. In an embodiment, the second frame body 43 is provided with an adjusting hole, one end of the connecting arm 71 is provided with an adjusting screw 721 corresponding to the adjusting hole, the threaded end of the adjusting screw 721 is threaded connected with the connecting arm 71 through the adjusting hole, and the adjusting screw 721 can move along the length direction of the adjusting hole in the adjusting hole. In the present application, the extension direction of the adjusting hole is the same as the length direction of the rack 1, that is, when the mounting position between the connecting arm 71 and the second frame body 43 is adjusted, the adjusting screw 721 is loosened, the inclination angle of the connecting arm 71 can be adjusted, and at the same time, the adjusting screw 721 can move along the length direction of the adjusting hole, so as to adjust the position of the rolling assembly 72 to meet the assembly of different specifications of the hub a and the solid tire b.

[0059] It should be noted that the roller assembly 72 includes a connecting shaft and a roller, which are standard parts and can be directly purchased. One end of the connecting shaft is fixedly connected with the connecting arm 71, and the other end of the connecting shaft is rotatably connected with the roller. In the process of pressing the outer wall of the solid tire b and pressing into the hub a, since the roller can rotate, the friction between the roller and the solid tire b is reduced, and the difficulty of manual tire mounting is reduced.

[0060] Further, as shown in Figure 3 、 Figure 7 , since the connecting arm 71 is connected with the second frame body 43 through the adjusting screw 721, when the rolling mechanism 7 presses the solid tire b into the hub a, the connecting arm 71 is subjected to a force opposite to gravity. In order to avoid the upward rotation of the connecting arm 71, which causes insufficient pressure when the solid tire b is pressed into the hub a, and cannot meet the assembly requirements. In an embodiment, the rolling mechanism 7 further comprises an adjusting assembly 73, which is connected with the second frame body 43. The adjusting assembly 73 can move along the axial direction of the turntable mechanism 2 until the output end of the adjusting assembly 73 abuts against the side wall of the connecting arm 71, thereby avoiding the upward rotation of the connecting arm 71. The stability of the hub a and the solid tire b during assembly is ensured. In some embodiments, in order to simplify the structure of the adjusting assembly 73, the adjusting assembly 73 can adopt a screw, and a threaded hole corresponding to the screw is formed on the second frame body 43. After the connecting arm 71 is installed, the installation height of the screw is adjusted until the end of the screw abuts against the side wall of the connecting arm 71 to achieve limiting.

[0061] It should be noted that in the present application, the second frame body 43 is slidably connected with the first frame body 41, as shown in Figure 3 , a limiting groove 411 is formed on the first frame body 41 along the axial direction of the driving shaft 42, and a limiting block 431 corresponding to the limiting groove 411 is arranged on the second frame body 43, so as to limit the sliding of the second frame body 43 relative to the first frame body 41. In some other embodiments, a linear guide rail can also be fixedly arranged on the first frame body 41, and a sliding block on the linear guide rail is connected with the second frame body 43, so as to improve the limiting precision of the second frame body 43 during movement.

[0062] In an embodiment, in order to simplify the structure of the pressing wheel mechanism 6 and reduce the production cost, as shown in Figure 3As shown, the pressing wheel mechanism 6 comprises a connecting member 61 and a pressing wheel assembly 62, the connecting member 61 is connected with the second frame body 43, and the connecting member 61 is movable along the axial direction of the rotating disc body 21; the pressing wheel assembly 62 is connected with the end of the connecting member 61 away from the second frame body 43. In order to simplify the structure of the connecting member 61 and facilitate the adjustment of the position of the pressing wheel assembly 62 along the axial direction of the rotating disc body 21, the connecting member 61 can be a screw extending along the axial direction of the rotating disc body 21, the threaded section of the screw penetrates through the second frame body 43, and the end of the threaded section is connected with the pressing wheel assembly 62. The position of the pressing wheel assembly 62 along the axial direction of the rotating disc body 21 can be adjusted to meet the tire mounting requirements of different specifications of the wheel hub a and the solid tire b. The pressing wheel assembly 62 is a standard part and can be directly purchased, and therefore the structure thereof will not be described herein.

[0063] In one embodiment, in order to ensure the installation strength of the frame 1, the frame 1 can be spliced by aluminum alloy or steel material. At the same time, in order to facilitate the movement of the whole manual tire mounting machine, universal wheels can be arranged at the bottom of the frame 1, which is easy to move. Further, in order to facilitate the arrangement of the rotating shaft 111 on the frame 1, a connecting plate 11 is arranged on the frame 1, and the rotating shaft 111 is located on the connecting plate 11, which is easy to process and assemble.

[0064] It should be noted that, in the present application, the assembly process of the manual tire mounting machine for the wheel hub a and the solid tire b is as shown in Figure 9 to Figure 11 First, as shown in Figure 9 , the wheel hub a and the tire are placed on the rotating disc body 21, and one end of the wheel hub shaft is inserted into the first limiting hole 2141. Then, the connecting frame 3 is moved to the upper side of the rotating disc mechanism 2, and the other end of the wheel hub shaft is inserted into the second limiting hole 511. Subsequently, the pressing wheel mechanism 6 and the rolling mechanism 7 are synchronously moved downward by operating the manual displacement table 4, and the pressing wheel mechanism 6 and the rolling mechanism 7 are arranged on the outer wall of the solid tire b. Further, the rotating disc mechanism 2 is manually rotated, as shown in Figure 10 , the solid tire b is pressed into the wheel hub a under the extrusion of the rolling mechanism 7.
