Description

Technical Field

[0001] The utility model relates to the technical field of tire production, and particularly relates to a PCR deformed tire repair device. Background Art

[0002] PCR tires are mainly used on cars, and customers have very strict requirements for dynamic balance. Dynamic balance detection is also an important detection item necessary in the tire manufacturing process. After PCR tires are vulcanized out of the vulcanizer, due to various reasons during circulation (such as tire jamming, extrusion, dropping, etc.), some tires will be deformed, resulting in unqualified dynamic balance detection in the subsequent process and becoming unqualified products.

[0003] Traditional tire deformation repair relies on manual repair. After heating the deformed tire in a heating box, the bead is supported by an object and the tire is shaped after natural cooling. Due to the non-adjustable tire rim spacing, tire stacking and extrusion deformation, and uneven support points, the qualified rate after repair is low, resulting in waste of labor and loss of waste tires:

[0004] 1) Repair status: During the entire shaping process, manual operation, tire stacking, uneven support points, and the tire rim spacing is basically one size and cannot be adjusted;

[0005] 2) Since it is manual operation, errors are likely to occur, resulting in a low qualified rate of dynamic balance after repair.

[0006] Based on this, the existing technology needs to be further improved. Content of the Utility Model

[0007] In view of the deficiencies of the prior art, a PCR deformed tire repair device is proposed, which solves the problems of non-adjustable tire rim spacing, tire stacking and extrusion deformation, and uneven support points in the above background art, resulting in a low qualified rate after repair, waste of labor and loss of waste tires.

[0008] To achieve the above object, the present utility model proposes the following technical solutions for implementation:

[0009] A PCR deformed tire repair device includes a first clamping mechanism and a second clamping mechanism for clamping and limiting a deformed tire. The distance between the first clamping mechanism and the second clamping mechanism is adjustable, and a pressurizing structure is provided on the first clamping mechanism or the second clamping mechanism to pressurize the deformed tire between the first clamping mechanism and the second clamping mechanism to restore its initial shape.

[0010] Further, the first clamping mechanism includes a first chuck, and a clamping ring is provided on the side of the first chuck close to the deformed tire. The clamping ring matches the shape of the bead of the deformed tire.

[0011] Further, the second clamping mechanism includes a second chuck, which is disposed opposite to the first chuck, and the deformed tire is clamped between the first chuck and the second chuck.

[0012] Further, a locking mechanism is further included, and the locking mechanism is disposed on the first clamping mechanism or the second clamping mechanism to lock the distance between the first clamping mechanism and the second clamping mechanism.

[0013] Further, the locking mechanism includes a locking rod, the locking rod penetrates through the first clamping mechanism, and a locking block is disposed at the bottom end of the locking rod to match with the second clamping mechanism to lock the distance between the first clamping mechanism and the second clamping mechanism.

[0014] Further, the locking rod is rotatably connected to the first clamping mechanism, a locking hole matching with the locking block is formed on the second clamping mechanism, and after the locking block is inserted into the locking hole, the locking block is rotated to be misaligned with the locking hole to achieve limiting.

[0015] Further, a rotating rod is fixedly connected to the top end of the locking rod, the end of the rotating rod is hinged to the output end of a locking cylinder, the locking cylinder is rotatably connected to the frame body, and the telescopic movement of the locking cylinder drives the rotating rod and the locking rod to rotate.

[0016] Further, the pressurizing structure is an air inlet pipe opened inside the locking rod and an air outlet opened on the side wall of the locking rod, and the air outlet is communicated with the air inlet pipe to inflate and pressurize the deformed tire between the first clamping mechanism and the second clamping mechanism.

[0017] Further, the second clamping mechanism further includes a secondary chuck, the secondary chuck is located below the second chuck, and the diameter of the secondary chuck is not less than the diameter of the second chuck.

[0018] Further, the second clamping mechanism further includes a jacking cylinder fixedly connected to the frame body, an output end of the jacking cylinder is fixedly connected with a mounting frame, and the second chuck and the secondary chuck are respectively mounted on the mounting frame.

[0019] Compared with the prior art, the comprehensive effects brought by the present utility model include:

[0020] By setting the first clamping mechanism and the second clamping mechanism to clamp and limit the deformed tire, it is convenient for the pressurizing structure to pressurize the inside of the deformed tire, increase the pressure inside the deformed tire, cause it to expand and gradually return to its original shape to achieve deformation repair. Using the above structure, the manual repair is transformed into equipment repair, the automation level is improved, and the labor intensity of the staff is reduced; by repairing the deformed tire separately, the stacking of tires is avoided, the deformation is reduced, and the tire is pressurized and shaped by the pressurizing structure, meeting the shaping pressure standard, improving the tire repair effect, and further improving the qualification rate of the dynamic balance after tire repair.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present invention.

[0027] In this article, terms such as "upper", "lower", "left", "right", "top", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0028] Such as Figures 1 to 4As shown in the figure, a PCR deformed tire repair device includes a first clamping mechanism and a second clamping mechanism for clamping and limiting a deformed tire. The distance between the first clamping mechanism and the second clamping mechanism is adjustable. A pressurizing structure is provided on the first clamping mechanism or the second clamping mechanism to pressurize the deformed tire between the first clamping mechanism and the second clamping mechanism to restore its initial shape.

[0029] By setting the first clamping mechanism and the second clamping mechanism to clamp and limit the deformed tire, it is convenient for the pressurizing structure to pressurize the inside of the deformed tire, increasing the pressure inside the deformed tire, causing it to expand and gradually return to its original shape to achieve deformation repair. Using the above structure, manual repair is transformed into equipment repair, improving the automation level and reducing the labor intensity of workers; by repairing the deformed tire separately, tire stacking is avoided, deformation is reduced, and the tire is pressurized and shaped through the pressurizing structure, meeting the shaping pressure standard, improving the tire repair effect, and further increasing the qualified rate of dynamic balance after tire repair.

[0030] In the PCR deformed tire repair device of this embodiment, the first clamping mechanism includes a first chuck 1. A clamping ring 2 is provided on the side of the first chuck 1 close to the deformed tire, and the shape of the clamping ring 2 matches the bead of the deformed tire.

[0031] Specifically, the first clamping mechanism and the second clamping mechanism are arranged vertically opposite to each other. The first chuck 1 is horizontally arranged, and the clamping ring 2 is located below the first chuck 1. The edge of the longitudinal section of the first chuck 1 is a smooth chamfer, the outer edge of the clamping ring 2 is arc-shaped, and the connection between the clamping ring 2 and the first chuck 1 is also an arc chamfer structure. Through the above structure, the edges of the clamping ring 2 and the first chuck 1 match the bead cross-section shape of the tire, effectively limiting and clamping the tire, and at the same time sealing the inside of the clamped deformed tire to smoothly achieve internal tire pressurization and complete expansion repair.

[0032] Preferably, the clamping ring 2 and the first chuck 1 are integrally formed, avoiding relative movement between the clamping ring 2 and the first chuck 1, which affects the alignment effect with the tire and ensures effective limiting.

[0033] In the PCR deformed tire repair device of this embodiment, the second clamping mechanism includes a second chuck 3. The second chuck 3 is arranged opposite to the first chuck 1, and the deformed tire is clamped between the first chuck 1 and the second chuck 3.

[0034] Specifically, the second chuck 3 is horizontally arranged, and a clamping ring 2 is provided above it. The first chuck 1 and the second chuck 3 are coaxially arranged, clamping and limiting the deformed tire from the upper side and the lower side respectively, and at the same time fitting with the beads on the upper and lower sides to achieve sealing of the tire interior, ensuring that the pressurizing structure effectively increases the pressure inside the deformed tire to make it expand and achieve repair.

[0035] By setting it into an upper and lower chuck structure, the entire circumferential direction of the deformed tire is evenly supported, the bead is evenly stressed, and the repair effect is good.

[0036] Specifically, the second clamping mechanism further includes a lifting cylinder 13 fixedly connected to the frame 9. The output end of the lifting cylinder 13 is fixedly connected with a mounting frame 14, and the second chuck 3 is mounted on the mounting frame 14. The lifting cylinder 13 drives the second chuck 3 to move up and down to approach or move away from the first chuck 1, which is convenient for loading and unloading the deformed tire, improves the degree of automation, and reduces the labor intensity.

[0037] Preferably, guide rods slidably connected to the frame 9 are respectively arranged on both sides of the lifting cylinder 13. The guide rods are fixedly connected to the second chuck 3 to realize the guidance of the vertical up and down movement of the second chuck 3.

[0038] In the PCR deformed tire repair equipment of this embodiment, a locking mechanism is further included. The locking mechanism is arranged on the first clamping mechanism or the second clamping mechanism to lock the distance between the first clamping mechanism and the second clamping mechanism.

[0039] Specifically, the locking mechanism is set to limit the distance between the first chuck 1 and the second chuck 3, so as to prevent the first chuck 1 and the second chuck 3 from being displaced when the pressure inside the deformed tire increases and expands, resulting in the internal part of the deformed tire communicating with the outside, affecting the airtightness inside the tire, and reducing the expansion repair effect.

[0040] In the PCR deformed tire repair equipment of this embodiment, the locking mechanism includes a locking rod 4. The locking rod 4 penetrates through the first clamping mechanism, and a locking block 5 is arranged at the bottom end of the locking rod 4 to match with the second clamping mechanism to lock the distance between the first clamping mechanism and the second clamping mechanism.

[0041] Specifically, the locking rod 4 penetrates through the first chuck 1 and is coaxially arranged with the first chuck 1. The bottom end of the locking rod 4 protrudes from the first chuck 1, and the locking block 5 is inserted into the second chuck 3 to realize locking with the second chuck 3, thereby fixing the distance between the two chucks and ensuring the clamping and sealing effect on the deformed tire.

[0042] Preferably, the length of the locking rod 4 extending out of the first chuck 1 is adjustable to meet the clamping and sealing requirements of tires with different thicknesses, so as to realize that the rim spacing can be adjusted and set to meet the rim spacing standard.

[0043] Specifically, the first chuck 1 is fixedly sleeved on the sleeve 15, and a sealing ring is arranged between the first chuck 1 and the sleeve 15. The sleeve 15 is threadedly connected to the periphery of the guide post 16. The locking rod 4 is arranged inside the guide post 16, and a sealing ring is arranged between the locking rod 4 and the guide post 16. The guide post 16 is fixed on the frame body 9. When it is necessary to adjust the extending length of the locking rod 4, rotate the sleeve 15 to realize the up and down movement of the sleeve 15 outside the guide post 16 through thread cooperation, drive the first chuck 1 to move, and then realize the change of the extending length of the locking rod 4.

[0044] In the PCR deformed tire repair equipment of this embodiment, the locking rod 4 is rotationally connected to the first clamping mechanism, and a locking hole 6 matching the locking block 5 is opened on the second clamping mechanism. After the locking block 5 is inserted into the locking hole 6, rotate the locking block 5 to make it misaligned with the locking hole 6 to realize the limit.

[0045] Specifically, through the above settings, the first chuck 1 and the second chuck 3 approach each other, so that the locking rod 4 drives the locking block 5 to be inserted into the locking hole 6 on the second chuck 3. Then, the locking rod 4 rotates to drive the locking block 5 to rotate, making it misaligned with the locking hole 6, preventing the locking block 5 from detaching from the second chuck 3, and realizing the locking limit.

[0046] Preferably, convex blocks are arranged on the circumference of the locking block 5 symmetrically centered on the axis of the locking rod 4, preferably in a plum blossom shape. The locking hole 6 matches the shape of the convex blocks. After the locking block 5 rotates, the convex blocks are staggered with the locking hole 6, and the convex blocks abut against the second chuck 3 to realize the limiting effect.

[0047] In the PCR deformed tire repair equipment of this embodiment, the top end of the locking rod 4 is fixedly connected with a rotating rod 7. The end of the rotating rod 7 is hinged to the output end of the locking cylinder 8. The locking cylinder 8 is rotationally connected to the frame body 9, and the telescopic movement of the locking cylinder 8 drives the rotating rod 7 and the locking rod 4 to rotate.

[0048] Specifically, the rotating rod 7 is arranged perpendicular to the locking rod 4, which is convenient for driving the locking rod 4 to rotate through the rotating rod 7. Through the above structure, when the locking block 5 is inserted into the second chuck 3, the locking cylinder 8 contracts, rotates with the frame body 9 itself, and at the same time, its output end drives the rotating rod 7 and the locking rod 4 to rotate, realizing the locking limit of the locking block 5.

[0049] In the PCR deformed tire repair equipment of this embodiment, the pressurizing structure is an air inlet pipe 10 opened inside the locking rod 4 and an air outlet 11 opened on the side wall of the locking rod 4. The air outlet 11 is communicated with the air inlet pipe 10 to inflate and pressurize the deformed tire between the first clamping mechanism and the second clamping mechanism.

[0050] Specifically, inflation is carried out inside the deformed tire to increase the pressure, enabling it to expand and repair. Compressed air is used to inflate and shape the tire to meet the shaping pressure standard. The air outlet 11 is opened at one end of the locking rod 4 extending out of the first chuck 1, and the top end of the air inlet pipe 10 is connected to an air source through a thread head.

[0051] Preferably, by switching the compressed air source to a steam source, the preheating of the tire before operation can be cancelled. Heating, softening, and shaping functions are achieved by injecting steam to meet the requirements of the three elements of tire vulcanization: temperature, time, and pressure, further improving the qualified rate of the dynamic balance after tire repair.

[0052] In the PCR deformed tire repair equipment of this embodiment, the second clamping mechanism further includes a secondary chuck 12. The secondary chuck 12 is located below the second chuck 3, and the diameter of the secondary chuck 12 is not less than that of the second chuck 3.

[0053] Specifically, both the first chuck 1 and the second chuck 3 are detachably installed to facilitate the replacement of chucks with different size specifications to clamp different specifications of tires and fit the bead to achieve internal tire sealing. The secondary chuck 12 is installed on the mounting bracket 14. By assembling the secondary chuck 12, support is provided for the deformed tire to prevent the support surface of the second chuck 3 from being too small, resulting in concentrated stress on the deformed tire on the second chuck 3 and causing deformation, which affects the internal tire sealing effect, thereby reducing the number of times of replacing the specifications of the chuck structure.

[0054] Preferably, the mounting bracket 14 includes a guide sleeve and a guide post. The secondary chuck 12 is arranged on the guide sleeve. The guide sleeve is threadedly connected to the guide post, and a sealing ring is provided at its top end. Rotating the guide sleeve drives the secondary chuck 12 and the second chuck 3 to move up and down to achieve fine adjustment of the position of the second chuck 3 and improve the adjustment flexibility.

[0055] Specifically, an installation cavity for connecting the locking head 5 is opened above the guide post. The air inlet pipe 10 passes through the bottom of the locking column 4 and communicates with the installation cavity. When compressed air is introduced into the air inlet pipe 10, the gas enters the tire from the air outlet 11 and also enters the installation cavity from the top. Since the installation cavity is connected to the tire through the gap between the locking rod 4 and the locking hole 6, the sealing effect can be ensured. At the same time, the installation cavity, that is, the penetration setting of the air inlet pipe 10, facilitates the impurities in the compressed air to vertically enter the installation cavity from the air inlet pipe 10, thereby preventing the accumulation of impurities in the air inlet pipe 10 and causing corrosion, which affects normal use.

[0056] Specifically, two or more sets of the first clamping mechanism and the second clamping mechanism are respectively provided in this application to improve the repair and processing efficiency.

[0057] Specifically, an electric control system is also provided in the repair equipment of this embodiment. When performing repair operations:

[0058] First, manually open the air source valve and turn on the power button. Then, place the tire on the second chuck 3 and manually align it. Press the start (or rise) button of the electric control system. The lifting cylinder 13 moves upward and stops after reaching the position of the magnetic switch. The magnetic switch is set to play a positioning role. The locking cylinder 8 locks and stops after reaching the position of the magnetic switch. Preferably, a mechanical structure is also provided for limiting to ensure the limiting effect. The pneumatic cut-off valve in the electric control system acts, and the tire starts to inflate. When the tire is inflated to the set pressure of the pressure switch set between the first chuck 1 and the second chuck 3, thereafter, the pneumatic cut-off valve remains open. At the same time, during this process, due to the increase in the tire pressure, the lifting cylinder moves downward a certain distance, and the distance between the chucks gradually becomes larger until the limit position, that is, the standard rim spacing, to form a rigid connection. The time relay in the electric control system starts timing until the set time. The pneumatic cut-off valve acts, and the tire starts to exhaust. When the tire exhausts to the set pressure of the pressure switch, it stops to achieve evacuation. The lifting cylinder 13 moves upward and stops after reaching the position of the magnetic switch. The locking cylinder 8 opens and stops after reaching the position of the magnetic switch. The lifting cylinder 13 moves downward to reset and stops after reaching the position of the magnetic switch. Take the tire and manually remove it. Repeat the above steps to achieve continuous maintenance. If a fault occurs during the operation process, press the reset button in the electric control system to return to the previous action before the faulty action occurs.

[0059] After the maintenance is completed, manually turn off the power button and close the air source valve.
