Description

Technical Field

[0001] The invention relates to a tire assembly device, in particular to a lock ring rim tire assembly device. Background Art

[0002] Ordinary tires are generally assembled and disassembled using a tire disassembler (installing and unloading tires). However, in the assembly of beadlock rim tires, since the beadlock and rim are two independent components connected by bolts, the beadlock and rim are not used as with current tire disassemblers. Current beadlock rim tire assembly is generally done directly by hand. Specifically, the beadlock is removed, and then one side of the tire is inserted into the rim. Next, the beadlock is inserted into the rim, and the tire is pressed completely and evenly, and the bolts are locked in. The other side of the tire is then pressed in through the beadlock. In the current beadlock rim tire assembly, since the rim height is much lower than the width of the tire itself, inserting the beadlock onto the rim, pressing the tire completely and evenly, and locking the bolts in is difficult, and the assembly efficiency is low, which affects the production capacity of beadlock rim tire assembly. Summary of the Invention

[0003] The purpose of the present invention is to provide a beadlock rim tire assembly device which can facilitate the assembly of beadlock rim tires, reduce labor intensity and operation difficulty, and improve assembly efficiency.

[0004] The technical solution of the present invention is:

[0005] A locking wheel rim tire assembly device, comprising:

[0006] A frame, the frame including a tire support plate for supporting the tire and a lower mounting plate located below the tire support plate;

[0007] The rim lifting device includes a rim positioning ring for positioning the rim and a lifting actuator provided on the lower mounting plate for lifting the rim positioning ring. The rim positioning ring is located above the lower mounting plate. The tire support plate is provided with a rim positioning ring opening so that the rim positioning ring can be moved above or below the tire support plate through the rim positioning ring opening.

[0008] The rim pressing mechanism is arranged on the lower mounting plate and is used to press the rim onto the rim positioning ring;

[0009] The tire pressing device is arranged on the frame and comprises an upper pressing plate located above the tire supporting plate and an upper pressing plate moving mechanism for moving the upper pressing plate.

[0010] The specific use of the lock ring rim tire assembly equipment of this scheme is as follows:

[0011] First, adjust the lock ring rim tire assembly equipment to the initial state. At this time, the rim lifting device drives the rim positioning ring to move down into position, and the rim positioning ring is located below the rim positioning ring opening; then, put the rim on the rim positioning ring and use the rim positioning ring to position the rim. At this time, one end of the rim extends upward through the rim positioning ring opening to the top of the tire support plate; then, the rim is pressed against the rim positioning ring by the rim pressing mechanism to prevent the rim from being offset during the subsequent process of inserting one side of the tire into the rim, which would affect the tire assembly;

[0012] Second, one side of the tire is inserted into the rim, while the tire is supported on the tire support plate; then, the upper pressure plate moving mechanism moves the upper pressure plate to just above the tire; and the rim clamping mechanism releases the rim;

[0013] Third, the rim lifting device drives the rim positioning ring to move upward. During this process, the tire will be placed on the rim positioning ring and move upward with the rim positioning ring; when the rim positioning ring moves up into place, the upper pressure plate presses the tire so that the bead on one side of the tire is stuck in the groove of the rim; then, the locking ring is inserted, the bolts are locked, and the locking ring is locked on the rim to complete the assembly of the locking ring rim and tire; then, the rim lifting device drives the rim positioning ring to move down into place. During this process, the assembled locking ring rim and tire will descend together with the rim positioning ring until the assembled locking ring rim and tire are supported on the tire support plate. After that, the assembled locking ring rim and tire can be taken out, which can facilitate the assembly of the locking ring rim and tire, reduce labor intensity and operation difficulty, and improve assembly efficiency.

[0014] Preferably, the rim clamping mechanism is a lever-type clamping cylinder comprising a rotating pressure arm for pressing the rim against the rim retaining ring and a clamping cylinder for rotating the rotating pressure arm. The clamping cylinder is mounted on the lower mounting plate. In this manner, the rotating pressure arm of the lever-type clamping cylinder can be used to press the rim against the rim retaining ring, resulting in a simple structure and easy operation.

[0015] Preferably, it also includes a press-fitting anti-error limiting device, which includes a floating plate located between the rim positioning ring and the lower mounting plate, a vertical guide hole arranged on the lower mounting plate, a vertical guide rod sliding along the vertical guide hole, a guide rod stopper arranged at the lower part of the vertical guide rod and a return spring sleeved on the vertical guide rod, the guide rod stopper is located below the lower mounting plate, the return spring is located between the floating plate and the lower mounting plate, and the edge of the floating plate is provided with a rotating pressure arm limiting baffle extending downward; when the lifting actuator drives the rim positioning ring to move upward, and the guide rod stopper rests on the lower mounting plate under the action of the return spring, the rotating pressure arm limiting baffle is located on one side of the rotating pressure arm, which is used to prevent the clamping cylinder from driving the rotating pressure arm to rotate. During the specific use of the lock-rim rim tire assembly equipment, the operator is required to follow the specified steps. However, in actual operation, failure to follow the specified steps may affect the normal operation of the equipment. Specifically, after the rim lifting device drives the rim locating ring upward, if the operator mistakenly controls the rotating pressure arm of the lever clamping cylinder to press down, the rim locating ring and the rotating pressure arm will collide during the downward movement of the rim locating ring, which may easily cause the lever clamping cylinder to malfunction and affect the normal operation of the equipment. To solve this problem, this solution specifically provides a press-fit error prevention limiter, which can effectively avoid the above-mentioned problems without affecting the normal operation of the equipment.

[0016] Preferably, the upper pressing plate moving mechanism is a rotary cylinder for driving the upper pressing plate to rotate and move. This structure is simple and easy to operate.

[0017] Preferably, a pressing block is provided on the lower surface of the upper pressing plate. The lower surface of the pressing block is a pressing slope, with the side of the pressing slope facing away from the upper rotating cylinder being inclined downward. Thus, during the tire pressing process, the upper pressing plate engages the tire via the pressing slope of the pressing block. The pressing slope can better hold the tire in place and prevent movement, facilitating the engagement of the tire bead with the rim groove.

[0018] Preferably, the lifting actuator includes a vertical guide sleeve mounted on the lower mounting plate, a guide rod sliding along the vertical guide sleeve, and a lifting cylinder mounted on the lower mounting plate for lifting the rim retaining ring. The upper end of the guide rod is connected to the rim retaining ring. This ensures the stability of the lifting of the rim retaining ring.

[0019] Preferably, a lower limit block is provided on the guide rod, and the lower limit block is located below the lower mounting plate.

[0020] Preferably, the lower portion of the guide rod is provided with an external thread, and a threaded sleeve is provided on the external thread of the lower portion of the guide rod, and the threaded sleeve constitutes the lower stop block. In this way, the position of the lower stop block can be adjusted by adjusting the position of the threaded sleeve, and the lifting height of the rim locating ring can be adjusted to accommodate the installation requirements of different tire models.

[0021] As preferably, the middle part of the rim positioning ring is provided with a rim limiting boss that protrudes upwards, and the rim limiting boss is used to limit the rim. In this way, the rim can be limited by the rim limiting boss.

[0022] Preferably, the lower mounting plate and the tire support plate are both mounted on the frame by bolts.

[0023] The beneficial effects of the present invention are: facilitating the assembly of the lock ring rim tire, reducing labor intensity and operation difficulty, and improving assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0039] Specific embodiment 1: Figure 1 、 Figure 2 、 Figure 3 As shown, a locking rim tire assembly device includes a frame, a rim lifting device 2, a rim pressing mechanism 3, and a tire pressing device 4. The frame includes a tire support plate 1.1 for supporting the tire and a lower mounting plate 1.2 located below the tire support plate. The lower mounting plate and the tire support plate are both bolted to the frame. Alternatively, the lower mounting plate and the tire support plate can be welded or riveted to the frame, and the tire support plate can also be welded or riveted to the frame. The lower mounting plate and the tire support plate are both horizontally arranged.

[0040] The rim lifting device 2 includes a rim locating ring 2.1 for positioning the rim and a lifting actuator mounted on the lower mounting plate for raising and lowering the rim locating ring. The rim locating ring is located above the lower mounting plate. The axis of the rim locating ring is vertically aligned. The tire support plate is provided with a rim locating ring opening 1.3, through which the rim locating ring can be moved above or below the tire support plate. An upwardly protruding rim stop boss 2.5 is located in the center of the rim locating ring. The rim stop boss is a circular cone and is used to stop the rim.

[0041] The rim clamping mechanism 3 is mounted on the lower mounting plate and is used to clamp the rim against the rim retaining ring. Multiple rim clamping mechanisms are provided, evenly distributed around the circumference of the rim retaining ring. In this embodiment, there are four rim clamping mechanisms. The rim clamping mechanism is a lever-type clamping cylinder. The lever-type clamping cylinder includes a rotating clamping arm 3.1 for clamping the rim against the rim retaining ring and a clamping cylinder 3.2 for rotating the rotating clamping arm. The rotating axis of the rotating clamping arm is horizontally distributed. The clamping cylinder is mounted on the lower mounting plate.

[0042] The tire pressing device 4 is arranged on the frame and comprises an upper pressing plate 4.1 located above the tire supporting plate and an upper pressing plate moving mechanism 4.2 for moving the upper pressing plate.

[0043] The specific use of the lock bead rim tire assembly equipment of this embodiment is as follows:

[0044] First, as Figure 1 As shown, the lock ring rim tire assembly equipment is adjusted to the initial state. At this time, the rim lifting device drives the rim positioning ring to move down to its position, and the rim positioning ring is located below the rim positioning ring opening;

[0045] Next, place the rim 6 on the rim positioning ring, with one end of the rim supported on the rim positioning ring and the rim sleeved on the rim limiting boss. The rim is positioned by the rim limiting boss. At this time, one end of the rim extends upward through the opening of the rim positioning ring to the top of the tire support plate.

[0046] Next, the clamping cylinder drives one end of the rotating pressure arm to rotate downward into position, and the rotating pressure arm presses the rim tightly onto the rim positioning ring to prevent the rim position from shifting during the subsequent process of inserting one side of the tire into the rim, which will affect the tire assembly.

[0047] Second, if Figure 1 As shown, one side of the tire 7 is inserted into the rim, and the tire is supported on the tire support plate;

[0048] Then, if Figure 1 、 Figure 4 As shown, the upper pressure plate moving mechanism moves the upper pressure plate to just above the tire; the rim clamping mechanism releases the rim. Specifically, the clamping cylinder drives one end of the rotating pressure arm to rotate upward to a position to release the rim.

[0049] Third, if Figure 4 As shown, the rim lifting device drives the rim positioning ring to move upward. During this process, the tire will be placed on the rim positioning ring and move upward with the rim positioning ring; when the rim positioning ring moves up to the right position, the upper pressure plate presses the tire so that the bead on one side of the tire is stuck in the groove of the rim; then, the locking ring 8 is inserted, the bolts are locked, and the locking ring is locked on the rim to complete the lock ring rim tire assembly.

[0050] Fourth, if Figure 5 As shown, the rim lifting device drives the rim positioning ring to move down into place. During this process, the assembled locking rim tire will descend together with the rim positioning ring until the assembled locking rim tire is supported on the tire support plate. After that, the assembled locking rim tire can be taken out, which can facilitate the assembly of the locking rim tire, reduce labor intensity and operation difficulty, and improve assembly efficiency.

[0051] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 As shown, there are multiple tire pressing devices 4, distributed around the rim locating ring. In this embodiment, there are four tire pressing devices. The tire pressing device also includes a mounting bracket 4.5 disposed on the upper surface of the tire support plate. The upper platen movement mechanism is a rotary cylinder for driving the upper platen's rotation. In this embodiment, the rotary cylinder is fixed to the upper end surface of the mounting bracket.

[0052] The lower surface of the upper pressure plate is also provided with a pressing block 4.3. The lower surface of the pressing block forms a pressing slope 4.4, which slopes downward on the side facing away from the upper rotating cylinder. During the tire press-fitting process, the upper pressure plate engages the tire via the pressing slope of the pressing block. This slope effectively holds the tire in place and prevents movement, facilitating the engagement of the tire's bead with the wheel rim's retaining groove. In this embodiment, the pressing block is plastic to protect the tire; however, it could alternatively be metal.

[0053] The lifting actuator includes a vertical guide sleeve mounted on the lower mounting plate, a guide rod 2.3 that slides along the vertical guide sleeve, and a lifting cylinder 2.2 mounted on the lower mounting plate for raising and lowering the rim retaining ring. The upper end of the guide rod is connected to the rim retaining ring, ensuring the stability of the rim retaining ring during lifting.

[0054] The guide rod is provided with a lower stopper 2.4, located below the lower mounting plate. In this embodiment, the lower portion of the guide rod is provided with external threads, which are capped with a threaded sleeve, forming the lower stopper. Adjusting the position of the sleeve allows the position of the lower stopper to be adjusted, thereby adjusting the height of the wheel rim retainer to accommodate the installation requirements of different tire models.

[0055] Specific embodiment 2: The rest of the structure of this embodiment refers to specific embodiment 1, except that:

[0056] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, a locking ring rim tire assembly device also includes a press-fitting error-prevention limiting device 5. The press-fitting error-prevention limiting device includes a floating plate 5.1 located between the rim positioning ring and the lower mounting plate, a vertical guide hole 5.3 provided on the lower mounting plate, a vertical guide rod 5.2 sliding along the vertical guide hole, a guide rod stopper 5.5 provided at the lower part of the vertical guide rod, and a reset spring 5.4 sleeved on the vertical guide rod. The guide rod stopper is located below the lower mounting plate. The reset spring is located between the floating plate and the lower mounting plate. The lower end of the reset spring abuts against the lower mounting plate, and the upper end of the reset spring abuts against the floating plate. A floating plate opening is provided in the middle of the floating plate, and the piston rod and guide rod of the lifting cylinder pass through the floating plate opening. A rotating pressure arm limiting baffle 5.6 extending downward is provided on the edge of the floating plate, and the rotating pressure arm limiting baffle is an annular baffle.

[0057] like Figure 4 As shown, when the lifting actuator drives the rim positioning ring to move upward, and the guide rod stopper rests on the lower mounting plate under the action of the reset spring, the rotating pressure arm limiting baffle is located on one side of the rotating pressure arm, which is used to prevent the clamping cylinder from driving the rotating pressure arm to rotate.

[0058] During the specific use of the lock ring rim tire assembly equipment, the operator is required to install the specified steps. However, in the actual operation process, the normal operation of the equipment may be affected due to failure to install the specified steps. Specifically, after the rim lifting device drives the rim positioning ring to move up, if the operator mistakenly controls the rotary pressure arm of the lever clamping cylinder to press down, the rim positioning ring and the rotary pressure arm will collide during the downward movement of the rim positioning ring, which may easily cause the lever clamping cylinder to malfunction and affect the normal operation of the equipment. In order to solve this problem, this solution specifically sets up a press-fit anti-error limiting device, which can effectively avoid the above problems without affecting the normal operation of the equipment. Specifically,

[0059] When the wheel rim is lifted up, the wheel rim positioning ring is moved upward by the wheel rim lifting device, and the floating plate moves upward with the wheel rim positioning ring under the action of the return spring until the guide rod stopper contacts the lower mounting plate. At this time, the rotating pressure arm limiting baffle on the floating plate is located on one side of the rotating pressure arm, which is used to block the clamping cylinder from driving the rotating pressure arm to rotate. In this way, the rotating pressure arm can be blocked by the rotating pressure arm limiting baffle. Even if the operator mistakenly controls one end of the rotating pressure arm of the lever clamping cylinder to rotate and press downward, it will be blocked by the rotating pressure arm limiting baffle and cannot be rotated and pressed downward. Therefore, after the wheel rim lifting device drives the wheel rim positioning ring to move upward, the problem of the wheel rim positioning ring and the rotating pressure arm colliding during the subsequent downward movement of the wheel rim positioning ring due to the operator's mistaken control of the rotating pressure arm of the lever clamping cylinder can be effectively solved, thereby causing the lever clamping cylinder to malfunction and affecting the normal operation of the equipment.

[0060] In the fourth step of the first embodiment, after the rim lifting device drives the rim positioning ring to move down to its proper position, the rim positioning ring will abut against the floating plate and drive the floating plate to move down to its proper position, which will not affect the normal operation of the equipment.

[0061] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still fall within the scope of protection of the technical solution of the present invention.
