Description

Technical Field

[0001] This utility model relates to the field of tire mold cleaning technology, and in particular to a quick clamping device for in-situ laser cleaning of the upper side plate of a tire mold. Background Technology

[0002] After prolonged use, tire vulcanizing molds accumulate vulcanized rubber residue, release agent residue, and carbon deposits on the cavities of the tread blocks and upper side plates. Regular cleaning is necessary to ensure tire molding quality. Laser cleaning, due to its lack of consumables, non-destructive nature, and high cleanliness, has gradually replaced traditional methods such as sandblasting, dry ice, and chemical immersion.

[0003] However, existing laser cleaning methods for tire molds, whether offline or online, generally suffer from the following problems:

[0004] (1) Low efficiency of offline cleaning: The mold needs to be disassembled as a whole and hoisted to a special cleaning station, which results in long downtime, occupies crane resources, and has high transportation costs. Furthermore, repeated disassembly and assembly of the mold affects accuracy.

[0005] (2) Lack of a unified centering benchmark: The existing online cleaning device requires manual repeated alignment of the mold center during installation, which results in poor centering accuracy and time consumption. This leads to the cleaning rotation trajectory not being concentric with the mold cavity, resulting in poor cleaning uniformity and missed cleaning or repeated cleaning.

[0006] (3) Poor specification adaptability: Molds with different outer diameters and different heights often require different cleaning tools, which are cumbersome to change and difficult to quickly adapt to multiple specifications of molds with one set of tools.

[0007] (4) Inconvenient replacement of cleaning head: The patterned block is a deep circumferential cavity and the side plate is an end face. The laser output direction required for the two is different. The existing solution requires stopping the machine to disassemble and realign the cleaning head, which is inefficient.

[0008] To address the aforementioned issues, there is a need for an online in-situ cleaning fixture that is simple in structure, can quickly center using the mold's own reference, can be quickly adapted to multiple mold specifications, and can quickly replace cleaning heads with different light emission methods. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a quick clamping device for in-situ laser cleaning of the upper side plate of a tire mold, which addresses the shortcomings of the prior art.

[0010] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A quick clamping device for in-situ laser cleaning on the upper side plate of a tire mold, including a central mounting base, a rotary drive assembly, a cleaning head connecting base, and a cleaning head assembly;

[0011] The central mounting base is mounted on the swivel head assembly of the tire mold, the rotary drive assembly is mounted on the central mounting base, the cleaning head connecting base is mounted on the rotary drive assembly, the cleaning head assembly is movably mounted on the cleaning head connecting base, and the rotary drive assembly can drive the cleaning head connecting base to rotate the cleaning head assembly around the swivel head assembly of the tire mold in a circumferential direction, so as to perform laser cleaning on the inner wall of the upper side plate and the tread blocks of the inner side wall of the tire mold.

[0012] The beneficial effects of this utility model are: by using the geometric center of the plum blossom head assembly as the installation reference, the rotation axis of the entire rotary cleaning mechanism is automatically aligned with the central axis of the mold, eliminating the need for additional manual alignment operations, resulting in high alignment accuracy and quick installation; the rotary drive assembly drives the cleaning head assembly to rotate circumferentially around the center of the mold, enabling one-time completion of full-circumference laser cleaning of the inner wall of the upper side plate and the patterned blocks of the mold, resulting in uniform cleaning without any missed areas.

[0013] Based on the above technical solution, the present invention can be further improved as follows:

[0014] Further: The rotary drive assembly includes a motor, a rotary reducer, and a motor mounting plate. The rotary reducer is installed at the bottom of the plum blossom head assembly, the motor is installed on the rotary reducer, and the motor and the rotary reducer are connected by a coupling. The cleaning head connecting seat is installed on the rotary reducer through the motor mounting plate.

[0015] The beneficial effects of the above-mentioned further solutions are: by using a motor in conjunction with a rotary reducer to provide a stable rotary driving force, the reducer can increase the output torque and improve the rotational accuracy, ensuring that the cleaning head runs smoothly during circumferential rotation and that the laser cleaning trajectory is continuous and uniform; the motor mounting plate provides a stable mounting base for the cleaning head connecting seat.

[0016] Furthermore, the rotary drive assembly also includes a quick-release connection assembly, which includes a fixed block and a movable block. The fixed block is mounted on the motor mounting plate, and the movable block is disposed on the fixed block and detachably connected to the fixed block. The cleaning head connector is mounted on the movable block.

[0017] The beneficial effects of the above-mentioned further solution are: by detachably connecting the fixed block and the movable block, the entire cleaning head connector and cleaning head assembly can be quickly disassembled and assembled. When it is necessary to replace the cleaning head or perform equipment maintenance, it is not necessary to disassemble the entire rotary drive assembly, which is convenient to operate and greatly shortens the downtime.

[0018] Furthermore, the central axis of the central mounting base, the rotation axis of the rotary reducer, and the central axis of the plum blossom head assembly are arranged collinearly.

[0019] The beneficial effects of the above-mentioned further solution are: by setting the three axes collinearly, the rotational motion trajectory of the cleaning head assembly is ensured to be completely coincident with the geometric center of the mold cavity, and the focal trajectory of laser cleaning is always consistent with the annular surface of the pattern block and the side plate, resulting in good cleaning uniformity and no biased or missed cleaning.

[0020] Furthermore: the cleaning head connector is L-shaped, the horizontal section of the cleaning head connector is mounted on the rotary drive assembly, and the vertical section of the cleaning head connector is provided with a plurality of fixing holes, through which the cleaning head assembly is mounted on the vertical section of the cleaning head connector.

[0021] The beneficial effects of the above-mentioned further solution are: the L-shaped structure allows the cleaning head assembly to be adjusted in the vertical direction, and the installation height of the cleaning head assembly can be changed by selecting different fixing holes, thereby adapting to molds of different heights and improving the versatility of the device.

[0022] Furthermore, the quick clamping device for in-situ laser cleaning on the upper side plate of the tire mold also includes a horizontal arm. The horizontal arm is installed on the vertical section of the cleaning head connecting seat through the fixing hole, and the position of the horizontal arm on the vertical section of the cleaning head connecting seat can be adjusted through the fixing hole. The cleaning head assembly is slidably installed on the horizontal arm.

[0023] The beneficial effects of the above-mentioned further solution are: the cross arm provides a radial mounting base for the cleaning head assembly. By sliding and adjusting the position of the cleaning head assembly on the cross arm, the radius of rotation from the laser cleaning head to the center of the mold can be changed, thereby adapting to tire molds of different diameters and completing the cleaning of molds of various sizes without changing the tooling.

[0024] Further: The cleaning head assembly includes an angle plate, a clamping assembly, and a cleaning head. One end of the angle plate is mounted on the cross arm. The clamping assembly is rotatably connected to the angle plate. The cleaning head is clamped inside the clamping assembly. The laser emitted by the cleaning head can clean the inner wall of the upper side plate of the tire mold and the tread blocks of the inner side wall of the tire mold.

[0025] The beneficial effects of the above-mentioned further solution are: the laser emission angle of the cleaning head can be adjusted by the rotational connection between the angle plate and the clamping assembly, so that the same cleaning head can be used for cleaning at the upper side plate angle and the pattern block angle respectively; the clamping assembly can quickly clamp or release the cleaning head, which facilitates the installation and replacement of the cleaning head.

[0026] Furthermore, the cleaning head is provided with four red light indicator points. The two red light indicator points on the outer side are used to indicate the linewidth boundary position of the cleaning laser, and the two red light indicator points in the middle are used to indicate the focal length. When the two red light indicator points in the middle coincide on the surface being cleaned, it indicates that the cleaning head is at the focal length position.

[0027] The beneficial effects of the above-mentioned further solution are: by using four-point red light positioning, operators can intuitively and quickly determine whether the lateral position of the cleaning head is correct and whether it is in the optimal focal length position, without the need to use rulers to measure or repeatedly test cuts, which greatly shortens the clamping and adjustment time, while ensuring the consistency of the cleaning effect.

[0028] Furthermore, the cross arm has sliding grooves on its opposite sides, and the angle plate has guide blocks on its opposite sides corresponding to the sliding grooves. The guide blocks are precisely engaged in the sliding grooves on the corresponding sides. The angle plate is provided with a locking assembly for locking or releasing the angle plate and the cross arm.

[0029] The beneficial effects of the above-mentioned further solution are: through the sliding cooperation between the guide block and the slide groove, the angle plate is stably guided to slide on the cross arm, and no deviation will occur when adjusting the position; the locking component can quickly lock after the position is adjusted to the correct position, ensuring the stability of the cleaning head during the rotation cleaning process and guaranteeing the cleaning accuracy.

[0030] Furthermore, the angle plate is provided with an arc-shaped adjustment hole, and the clamping assembly is provided with a guide post. The guide post extends into the arc-shaped adjustment hole, and when the clamping assembly rotates relative to the angle plate, the guide post moves within the arc-shaped adjustment hole.

[0031] The beneficial effects of the above-mentioned further solution are: by cooperating with the arc-shaped adjustment hole and the guide post, the angle adjustment and guidance of the clamping component relative to the angle plate is realized, so that the cleaning head can rotate smoothly and be positioned within the preset angle range, ensuring that the laser always irradiates the surface to be cleaned at the optimal incident angle; at the same time, the arc-shaped adjustment hole plays a limiting role in the rotation range, preventing excessive rotation.

[0032] Furthermore, the clamping assembly includes a first clamping block and a second clamping block that are respectively semi-circular, and the first clamping block and the second clamping block cooperate with a clamp and a locking bolt to clamp or loosen the cleaning head.

[0033] The beneficial effects of the above-mentioned further solution are: the annular clamping structure formed by the first clamping block and the second clamping block can firmly clamp cleaning heads of different outer diameters, with strong adaptability; the combination of the clamp and the locking bolt is simple to operate, and can realize the quick clamping and release of the cleaning head without the need for special tools.

[0043] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0044] like Figures 1 to 5 As shown, this utility model provides a quick clamping device for in-situ laser cleaning on the upper side plate line of a tire mold, including a central mounting base 1, a rotary drive assembly 2, a cleaning head connecting base 3, and a cleaning head assembly 4.

[0045] The center mounting base 1 is fixed to the center hole of the swivel head assembly 17 of the tire mold by thread locking. The swivel head assembly 17 is located at the center of the tire mold, and its geometric center is the rotation center of the mold. The rotary drive assembly 2 is mounted on the center mounting base 1, the cleaning head connecting base 3 is mounted on the rotary drive assembly 2, and the cleaning head assembly 4 is movably mounted on the cleaning head connecting base 3.

[0046] The rotary drive assembly 2 can drive the cleaning head connecting seat 3 to rotate the cleaning head assembly 4 around the axis of the swivel head assembly 17. During the rotation, the laser cleaning head in the cleaning head assembly 4 emits a laser to perform laser cleaning on the inner wall of the upper side plate and the tread blocks of the tire mold. Since the rotation axis of the cleaning head assembly 4 coincides with the central axis of the swivel head assembly 17, the laser cleaning trajectory is completely concentric with the annular surface of the mold cavity, resulting in uniform cleaning without any missed areas.

[0047] Using the geometric center of the Phillips head assembly 17 as the installation reference, rapid alignment installation without the need for additional centering operations is achieved, significantly reducing clamping time. In practical applications, a threaded mounting hole can be machined at the center of the Phillips head assembly 17, and the center mounting seat 1 can be locked into this threaded mounting hole with screws. As an equivalent simplified solution, a threaded hole can also be directly tapped at the center of the Phillips head assembly 17 body, and the rotary drive assembly 2 can be directly installed into this threaded hole, eliminating the need for a separate center mounting seat 1 part.

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, in one or more embodiments of this utility model, the rotary drive assembly 2 includes a motor 5, a rotary reducer 6, and a motor mounting plate 7. The rotary reducer 6 is mounted on a central mounting base 1, the motor 5 is mounted on the rotary reducer 6, and the output shaft of the motor 5 is connected to the input shaft of the rotary reducer 6 via a coupling. The cleaning head connecting seat 3 is mounted on the output end of the rotary reducer 6 via the motor mounting plate 7.

[0049] Motor 5 is preferably a stepper motor, driven by pulse signals sent by the controller. The rotary reducer 6 converts the high-speed rotation of motor 5 into a low-speed, high-torque output, driving the cleaning head connector 3 to slowly and smoothly rotate the cleaning head assembly 4 around the mold center. Since laser cleaning only requires one full rotation (approximately 360°-365°) around the mold center to complete the cleaning, there is no need for angle closed-loop control. Cleaning is completed by rotating one full rotation in one direction, using the motor's starting position as the zero point, greatly simplifying the structure and control system. The type of motor 5 is not limited to a stepper motor; other types of drive motors such as servo motors and DC motors can also be used.

[0050] Optionally, in one or more embodiments of this utility model, the central axis of the central mounting base 1, the rotation axis of the rotary reducer 6, and the central axis of the plum blossom head assembly 17 are arranged collinearly to ensure that the rotational motion trajectory of the cleaning head assembly 4 is completely concentric with the mold cavity.

[0051] like Figure 1 , Figure 3 As shown, in one or more embodiments of this utility model, the rotary drive assembly 2 further includes a quick-release connection assembly, which includes a fixed block 8 and a movable block 9. The fixed block 8 is fixedly installed on the motor fixing plate 7, and the movable block 9 is disposed on the fixed block 8 and detachably connected to the fixed block 8. The cleaning head connecting seat 3 is installed on the movable block 9.

[0052] Specifically, a quick-release structure using a tapered pin and pull rivet can be adopted between the fixed block 8 and the movable block 9. The fixed block 8 is provided with a tapered pin hole and a pull rivet locking mechanism, and the movable block 9 is correspondingly provided with a pull rivet. During installation, the pull rivet on the movable block 9 is inserted into the tapered pin hole of the fixed block 8, and the pull rivet locking mechanism automatically locks the pull rivet, achieving quick fixation between the movable block 9 and the fixed block 8. During disassembly, pressing the release button releases the pull rivet locking mechanism, allowing the movable block 9, along with the cleaning head connector 3 and the cleaning head assembly 4, to be removed together.

[0053] With the quick-release connection assembly, operators can quickly disassemble and assemble the cleaning head connector 3 and the cleaning head assembly 4 without disassembling the motor 5 and the rotary reducer 6, which facilitates quick switching between different cleaning tasks or quick disassembly of the cleaning head part during equipment maintenance.

[0054] like Figure 1 , Figure 3 As shown, in one or more embodiments of this utility model, the cleaning head connecting seat 3 has an L-shaped structure. The horizontal section of the cleaning head connecting seat 3 is fixedly installed on the movable block 9, and multiple fixing holes are provided on its vertical section along the vertical direction. The cross arm 10 is installed on the vertical section of the cleaning head connecting seat 3 by bolts and fixing holes. By selecting different fixing holes, the installation height of the cross arm 10 in the vertical direction can be adjusted to adapt to molds of different height specifications. The cross arm 10 extends horizontally as a whole, and its extension direction is perpendicular to the vertical section of the cleaning head connecting seat 3. The cleaning head assembly 4 is slidably installed on the cross arm 10 and can slide along the length direction of the cross arm 10 to adjust its radial position.

[0055] like Figure 1 , Figure 4As shown, in one or more embodiments of this utility model, the cleaning head assembly 4 includes an angle plate 11, a clamping assembly 12, and a cleaning head 13. One end of the angle plate 11 is mounted on the cross arm 10. The clamping assembly 12 is rotatably connected to the angle plate 11 and can rotate and be positioned relative to the angle plate 11 within a certain angle range. The cleaning head 13 is clamped within the clamping assembly 12. The cleaning head 13 is a laser cleaning head, which has a laser emission path inside. The emitted laser beam can clean the inner wall of the upper side plate and the tread blocks of the tire mold.

[0056] By adjusting the rotation angle of the clamping assembly 12 relative to the angle plate 11, the laser emission direction of the cleaning head 13 can be changed, so that the cleaning angle of the upper side plate is aligned with the inner wall of the upper side plate, or the cleaning angle of the patterned block is aligned with the patterned block of the inner wall, thus meeting the cleaning needs of different parts.

[0057] In one or more embodiments of this utility model, the clamping assembly 12 includes a first clamping block and a second clamping block, each being semi-circular. When the first and second clamping blocks are engaged, they form an annular clamping space that matches the outer diameter of the cleaning head 13. The first and second clamping blocks cooperate with clamps and locking bolts to clamp or release the cleaning head 13. When replacing the cleaning head, simply loosen the locking bolts, remove the old cleaning head, insert the new cleaning head 13, and then re-lock it; the operation is simple and requires no special tools. Figure 1 , 2 Figures 4 and 5 show the structural schematic diagram of the clamping device for cleaning head 13 used to clean the inner wall of the upper side plate of the tire mold; as shown in Figures 4 and 5. Figure 6 and 7 The diagram shows a structural schematic of a clamping device after the cleaning head 13 has been replaced with a device for cleaning the tread blocks on the side wall of a tire mold.

[0058] In one or more embodiments of this utility model, the cleaning head 13 is provided with four red light indicator points for assisting in installation and positioning. The two outermost red light indicator points are used to indicate the boundary position of the cleaning laser linewidth (i.e., the coverage area of ​​the laser spot). By observing the positions of the two outermost red light points on the surface to be cleaned, the operator can visually determine whether the lateral position of the laser cleaning head is correct, ensuring that the laser spot coverage area matches the area to be cleaned.

[0059] The two central red light indicator points are used to indicate the focal length. When the two central red light indicator points coincide on the surface being cleaned, it indicates that the cleaning head 13 is exactly at the focal length position, at which point the laser energy density is highest and the cleaning effect is optimal. Based on this, the operator can quickly adjust the cleaning head 13 to the correct focal length position without using measuring tools or repeated trial cuts. The four-point red light positioning method makes the installation and positioning of the cleaning head 13 intuitive and efficient, significantly shortening the clamping and adjustment time while ensuring consistent cleaning results. In this embodiment, the cleaning head 13 can be a readily available laser cleaning head.

[0060] like Figure 1 , Figure 4 As shown, in one or more embodiments of this utility model, grooves 14 are respectively provided on the opposite side edges of the cross arm 10, and the grooves 14 extend along the length direction of the cross arm 10. Guide blocks 15 are respectively provided on the angle plate 11 corresponding to the two sides of the grooves 14. The guide blocks 15 fit precisely into the grooves 14 on the corresponding side and can slide along the grooves 14.

[0061] With the cooperation of the guide block 15 and the slide groove 14, the angle plate 11 can slide smoothly along the length of the cross arm 10 to adjust the radial distance from the cleaning head 13 to the center of the mold. After being adjusted to the appropriate position, the angle plate 11 and the cross arm 10 are locked and fixed by the locking assembly 16 provided on the angle plate 11.

[0062] In practice, the locking assembly 16 can take the form of a locking bolt, quick clamp, or eccentric locking handle. When a locking bolt is used, tightening the bolt will cause the angle plate 11 to press against the cross arm 10, thereby achieving locking by friction; loosening the bolt will release the lock and allow for position adjustment.

[0063] With the cooperation of the cross arm 10 and the angle plate 11, the rotation radius of the cleaning head 13 can be continuously adjusted within a large range, enabling the device to adapt to tire molds of different diameters, thus achieving the design goal of "one set of tooling, universal for multiple specifications". When cleaning molds of different diameters, simply loosen the locking component 16, slide the angle plate 11 to the target position, and then relock it. The operation is quick and requires no replacement of any parts.

[0064] like Figure 3As shown, in one or more embodiments of this utility model, the angle plate 11 is provided with an arc-shaped adjustment hole 18, and the clamping assembly 12 is provided with a guide post (not shown in the figure). The guide post extends into the arc-shaped adjustment hole 18. When the clamping assembly 12 rotates relative to the angle plate 11, the guide post moves along an arc within the arc-shaped adjustment hole 18. The arc-shaped adjustment hole 18 guides and limits the movement range of the guide post, making the rotation trajectory of the clamping assembly 12 stable and controllable. When the clamping assembly 12 rotates to the target angle, the guide post is fixed in the arc-shaped adjustment hole 18 by a locking nut or set screw, thereby achieving angle locking.

[0065] By cooperating with the guide post through the arc-shaped adjustment hole 18, the laser emission angle of the cleaning head 13 can be continuously and precisely adjusted within a preset range, ensuring that the laser beam always irradiates the surface to be cleaned at the optimal incident angle, thereby improving cleaning efficiency and cleaning quality.

[0066] like Figure 5 As shown, in practical applications, this device is installed on the upper mold of the tire vulcanizing machine. The operator aligns the center mounting base 1 with the threaded mounting hole in the center of the plum blossom head assembly 17 and tightens it with screws to complete the center positioning. Then, the rotary drive assembly 2 is installed on the center mounting base 1.

[0067] Based on the diameter and height specifications of the mold to be cleaned, the operator adjusts the installation height of the cleaning head assembly 4 through the fixing holes on the cross arm 10, and adjusts the rotation radius of the cleaning head 13 by sliding the angle plate 11 along the slide groove 14. After adjustment, it is locked in place by the locking assembly 16. Here, the locking assembly 16 can be a locking bolt, quick clamp, or eccentric locking handle, etc.

[0068] Depending on the area to be cleaned (upper side plate or patterned block), the operator adjusts the angle of the clamping assembly 12 relative to the angle plate 11 through the arc-shaped adjustment hole 18, so that the laser emission direction of the cleaning head 13 is aligned with the target cleaning surface. The position and focal length of the cleaning head 13 are finely adjusted using four red light indicator points: the two outer red light indicator points are observed to determine whether the line width boundary position is correct, and the two middle red light indicator points are observed to confirm whether the focal length is in place.

[0069] Start motor 5. After being reduced in speed and increased in torque by rotary reducer 6, motor 5 drives cleaning head connecting seat 3 to slowly rotate cleaning head 13 around the center of mold. At the same time, a laser control signal is sent to cleaning head 13 to begin full-circumference laser cleaning of the inner wall of the upper side plate or patterned block of the mold. After one rotation (approximately 360°-365°), motor 5 stops rotating, and the cleaning operation is completed.

[0070] When it is necessary to switch the cleaning pattern block or side plate, simply change the light emission angle of the cleaning head 13 through the arc-shaped adjustment hole 18; there is no need to remove and reinstall the cleaning head. When it is necessary to change the cleaning head with a different light emission mode, quickly loosen the original cleaning head through the clamping assembly 12, insert the new cleaning head, and then tighten it again; there is no need to disassemble the cross arm 10 and the angle plate 11, nor is it necessary to re-align.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
