For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0045] The following further explains and illustrates the present utility model in conjunction with specific embodiments.

[0046] As Figures 1-3 shown, a semi-automatic loading and unloading press-fitting machine provided in this embodiment includes: a bed body 10, a material lifting mechanism 20, and a power mechanism;

[0047] The material lifting mechanism 20 is vertically arranged on the bed body 10 and can be lifted and lowered, and is used for lifting and unloading the rear wheel 50 after press-fitting;

[0048] The material lifting mechanism 20 is symmetrically provided with lifting rods 21, and the lifting rods 21 can be horizontally and downwardly inclined, and are used for horizontally lifting and inclined unloading of the rear wheel 50 after press-fitting;

[0049] The material lifting mechanism 20 is further provided with an elastic member, which is used for automatically resetting the lifting rod 21 from an inclined state to a horizontal state after unloading;

[0050] The power mechanism is used to drive the material lifting mechanism 20 to lift and lower in the vertical direction.

[0051] As Figures 4-5 shown, the material lifting mechanism 20 is further provided with an upper support plate 23 and a lower support plate 24 in the vertical direction. The upper support plate 23 is fixedly connected to the driving end of the power mechanism;

[0052] The two sides of the upper support plate 23 and the lower support plate 24 are provided with side plates 25 for connecting the upper support plate 23 and the lower support plate 24;

[0053] The lower part of the lower support plate 24 is rotationally connected to the lifting rod 21.

[0054] One end of the elastic member is fixedly connected to the lifting rod 21, and the other end is fixedly connected upward to a connecting rod 251. The connecting rod 251 is fixedly arranged at the top of the side plate 25.

[0055] In this embodiment, the elastic member is a tension spring 22. The setting of the tension spring 22 enables the lifting rod 21 to automatically return to the horizontal position after unloading, improving the production efficiency.

[0056] The upper part of the side plate 25 is fixedly connected to the upper support plate 23. A first rotating shaft 26 is fixedly arranged between the lower parts of the two side plates 25. The upper part of the lower support plate 24 is rotatably sleeved on the first rotating shaft 26, and is used for driving the lower support plate 24 to rotate around the first rotating shaft 26 when the material lifting rod 21 inclines downward, so as to realize the inclination of the material lifting rod 21 relative to the horizontal plane;

[0057] A second rotating shaft 27 is fixedly arranged at the lower part of the lower support plate 24. The material lifting rod 21 is rotatably arranged on the lower support rod through the second rotating shaft 27, and is used for rotating through the maximum rim of the wheel rim when the material lifting rod 21 descends;

[0058] The first rotating shaft 26 and the second rotating shaft 27 are arranged perpendicular to each other.

[0059] As Figures 6-7 shown, one end of the bottom of the upper support plate 23 is arranged in a horizontal plane, and the other end is arranged in an inclined plane. The inclined plane is used to provide a rotating space and a limit for the lower support plate 24 during inclined discharging.

[0060] One end of the bottom of the upper support plate 23 arranged horizontally limits the clockwise rotation of the lower lifting plate around the first rotating shaft 26 caused by the center of gravity offset of the wheel 50 during material lifting, thereby improving the stability and safety of the material lifting of the wheel 50; at the same time, when the material lifting rod 21 returns to the horizontal position under the action of the tension spring 22 after inclined discharging, a limit is carried out, and the levelness of the material lifting rod 21 is improved.

[0061] The arrangement of the inclined plane at the bottom of the upper support plate 23 provides a space for the counterclockwise rotation of the lower support plate 24 during discharging, and at the same time limits the inclination angle of the material lifting rod 21, avoiding the phenomenon that the inclination angle of the material lifting rod 21 is too large and the wheel 50 slides out quickly and collides with the discharging mechanism 40, thereby improving the quality of the wheel 50.

[0062] As Figures 8-9 shown, a boss 211 is arranged at one end of the material lifting rod 21 perpendicular to the length direction of the material lifting rod 21, and a groove is formed through the boss 211 in the vertical direction;

[0063] The lower part of the lower support plate 24 penetrates through the groove and is rotatably connected to the boss 211 through the second rotating shaft 27, and the bottom surface of the lower support plate 24 is flush with or extends out of the bottom surface of the material lifting rod 21.

[0064] A first limiting surface 212 and a second limiting surface 213 are arranged in the groove. The first limiting surface 212 is arranged in an inclined plane, and is used to provide a rotating space and a limit when the material lifting rod 21 rotates upward from the horizontal direction around the second rotating shaft 27 in the counterclockwise direction;

[0065] The second limiting surface 213 is vertically arranged and abuts against the side surface of the lower support plate 24, and is used for limiting when the material lifting rod 21 rotates clockwise from top to bottom around the second rotating shaft 27 and returns to the horizontal position.

[0066] One surface of the material lifting rod 21 opposite to the boss 211 is provided with an arc surface 214.

[0067] The setting of the arc surface 214 enables the material lifting rod to smoothly pass through the rim flange, avoiding abrasion to the rim.

[0068] Preferably, it further includes a discharging mechanism 40. The discharging mechanism 40 is arranged on the inclined side of the material lifting rod 21 and is fixedly connected to the bed body 10; the discharging mechanism 40 is provided with a discharging power roller path 41 for conveying the wheels 50 after unloading.

[0069] The power mechanism is a press 30.

[0070] As Figures 10-12 shown, specifically, in the initial working position, the material lifting rod 21 is horizontally arranged. First, the rim of the wheel 50 is manually installed on the press-fitting lower die 12, and then the wheel hub is placed inside the rim to complete manual loading; then the driving end of the press 30 drives the press-fitting upper die 11 and the material lifting mechanism 20 to move downward. When the arc surface 214 of the material lifting rod 21 contacts the outer edge of the rim, the material lifting rod 21 rotates counterclockwise upward around the second rotating shaft 27 and passes through the maximum diameter of the outer edge of the rim. After passing through, since there is no contact between the material lifting rod 21 and the rim, the material lifting rod 21 rotates clockwise from top to bottom around the second rotating shaft 27 under the action of gravity and returns to the horizontal position. After the rim and the wheel hub are press-fitted, the driving end of the press 30 drives the material lifting mechanism 20 and the press-fitting upper die 11 to rise. When the material lifting rod 21 contacts the rim again, under the limitation of the second limiting surface 213, the material lifting rod 21 cannot rotate clockwise from the horizontal downward around the second rotating shaft 27. Therefore, the material lifting rod 21 horizontally lifts the wheel 50. When the wheel 50 is lifted upward to the specified position, the wheel 50 is manually pushed gently in the direction of the discharging power roller path 41 by hand. The center of gravity of the wheel 50 moves forward, breaking the original balance state of the material lifting rod 21. The material lifting rod 21 and the lower support plate 24 slowly tilt downward around the first rotating shaft 26, and the wheel 50 slowly slides into the discharging power roller path 41 along the inclined material lifting rod 21, completing the semi-automatic unloading of the wheel 50. After that, the material lifting rod 21 returns to the horizontal position under the action of the tension spring 22 and the bottom horizontal plane of the upper support plate 23 and enters the next round of material lifting and discharging.

[0071] A semi-automatic loading and unloading press-fitting machine provided by the present utility model has the following advantages:

[0072] 1. The setting of the elastic member enables the material lifting rod to automatically return to the horizontal position after discharging, preparing for the next round of material lifting, realizing the automatic switching between discharging and material lifting after wheel press-fitting, and improving the production efficiency.

[0073] 2. The setting of the inclined plane at the bottom of the upper support plate limits the position of the material lifting rod for inclined discharging, enabling the wheel to accurately enter the discharging roller to achieve wheel discharging, avoiding the bumps during manual discharging, and improving the wheel quality.

[0074] 3. The setting of the upper limit surface on the material lifting rod limits that the material lifting rod can only rotate upward from the horizontal and cannot rotate downward from the horizontal, improving the stability of wheel material lifting.

[0075] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
