Description

Technical Field

[0001] The utility model relates to the technical field of tire vulcanization equipment, in particular to an inflation clamping device after tire vulcanization. Background Art

[0002] After the tire is vulcanized, it is usually necessary to use an inflation device to inflate it so that the vulcanized tire can be naturally cooled in the inflated state. The inflation device includes an upper and lower chuck assembly, an upper chuck operating mechanism, a flip mechanism and a tire gripping mechanism. The upper chuck is an upper tray and an upper chuck that are vertically coaxially fixed. A locking ring is coaxially arranged on the top of the upper tray, and a locking shaft is coaxially connected to the bottom of the upper chuck; the lower chuck is a lower chuck and an inflation plate that are coaxially fixed in the same vertical direction. The inflation plate is installed on the flip mechanism, and the inflation plate is coaxially fixed in the inflation plate. A locking sleeve is provided which is higher than the lower chuck; the upper chuck operating mechanism comprises a rotating arm, a rotating shaft and a locking disc which are installed on a vertically lifting beam above the upper chuck assembly; the rotating shaft is coaxial with the locking disc, and its upper end is connected to the rotation center of the rotating arm, and a turning head at its lower end passes through the locking disc and the locking ring and extends into a turning hole provided on the upper tray; the locking hole of the locking disc and the locking ring, the locking shaft and the locking sleeve are all matched with each other in a staggered tooth structure; the two are separated when the teeth are staggered, and are combined when the teeth are aligned; when the locking disc and the locking ring have staggered teeth, the locking shaft and the locking sleeve have aligned teeth.

[0003] When the above-mentioned inflation device is working, the tire is placed on the lower chuck by the tire unloading mechanical claw of the main machine of the vulcanizer, and the crossbeam moves vertically downward to clamp the tire between the upper and lower chucks, so that the lock shaft enters the lock sleeve and is pressed down along the guide hollow shaft, and the outer tire mouth and the steel ring part of the chuck can be closely matched; then the cylinder of the upper chuck operating mechanism pushes the rotating arm to match the staggered teeth of the lock ring and the lock disc, and the lock shaft and the lock sleeve match the teeth, and the upper chuck is separated from the upper chuck operating mechanism. Compressed air is introduced from the inflation disc into the inner cavity of the tire for inflation, and the upper chuck is slowly pushed up by the inflated tire. When the teeth of the lock shaft and the lock sleeve are supported, it reaches the position required by the rim width. The role of the clamping ring is to support the teeth of the lock shaft to prevent the lock shaft from falling out during the tire flipping process. The distance between the upper chuck and the lower chuck can be adjusted by the distance adjustment mechanism set on the flipping mechanism (vertical arm) to adapt to tires of various specifications. The inflation device of this structure is not only cumbersome in the inflation and clamping process of the tire, but also inefficient. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The inflation clamping device after tire vulcanization includes a fixed seat 1, a lower chuck 2, an upper chuck 3, a lower lock buckle 4, a movable seat 5, an upper lock buckle 6, a rod-shaped component 7, an elastic component 8, a locking plate 9, and a connecting seat 10. Each part and the relationship between them are described in detail below.

[0020] The lower chuck 2 is fixed to the fixed seat 1, and the lower chuck 2 is sleeved on the fixed seat 1. The lower chuck 2 is pressed on the fixed seat 1 by a clamping assembly, so that the lower chuck 2 and the fixed seat 1 are fastened together. The clamping assembly can be composed of screws and a pressure ring. A threaded hole is provided on the axial end face of the fixed seat 1, and a shoulder is provided on the peripheral surface of the fixed seat 1. The lower chuck 2 is sleeved on the fixed seat 1 and supported by the shoulder. The screw is passed through the pressure ring and threadedly connected to the threaded hole on the axial end face of the fixed seat 1, so that the pressure ring generates pressure on the lower chuck 2, so that the lower chuck 2 is clamped between the pressure ring and the shoulder. Of course, the lower chuck 2 and the shoulder can also be welded to make the lower chuck 2 sleeved on the fixed seat 1.

[0021] The fixing seat 1 is provided with a first hole 1a, and at least a part of the lower lock buckle 4 is matched with the first hole 1a; the first hole 1a is arranged along the axial direction of the fixing seat 1, and there may be a distance between the lower lock buckle 4 and the inner wall of the first hole 1a. In this case, a support mechanism (not shown in the figure) is used to match the lower lock buckle 4 so that a part of the lower lock buckle 4 is located in the first hole 1a. Alternatively, the lower lock buckle 4 may be matched with the first hole 1a in an interference fit manner.

[0022] The upper chuck 3 and the lower chuck 2 are arranged opposite to each other, the upper chuck 3 is fixed on the movable seat 5, the movable seat 5 is sleeved on the upper lock buckle 6 and is fixed with the upper lock buckle 6 in the axial direction, after one end of the upper lock buckle 6 is plugged into the lower lock buckle 4, the upper lock buckle 6 is driven to rotate so that the upper lock buckle 6 and the lower lock buckle 4 form an axially limited combination.

[0023] In this embodiment, the lower lock buckle 4 includes a first cylinder 4a, and a first limiting component 4b having a first polygonal inner hole 4c is provided on the inner wall at one end of the first cylinder 4a, and a first step 4d is formed between the first limiting component 4b and the first cylinder 4a. The upper lock buckle 6 includes a first connecting portion 6a, and a first polygonal protrusion 6b is provided at one end of the first connecting portion 6a. After the first polygonal protrusion 6b passes through the first polygonal inner hole 4c, the upper lock buckle 6 is driven to rotate so that the first polygonal protrusion 6b abuts against the first step 4d, so that the upper lock buckle 6 and the lower lock buckle 4 form an axial limiting combination.

[0024] The upper locking buckle 6 also includes a second connecting portion 6c, which is fixed to the other end of the first connecting portion 6a. An annular groove 6d is provided on the circumference of the second connecting portion 6c, and a part of the movable seat 5 is clearance-matched with the annular groove 6d.

[0025] Based on the above structure, when the upper locking buckle 6 rotates, since a part of the movable seat 5 is loosely matched with the annular groove 6d, the movable seat 5 will not rotate with the upper locking buckle 6, and a part of the movable seat 5 is combined with the annular groove on the peripheral surface of the upper locking buckle 6, and the movable seat 5 restricts the axial movement of the upper locking buckle 6.

[0026] One end of the rod-shaped component 7 is fixed to the movable seat 5, the locking disc 9 is sleeved on the connecting seat 10 and is circumferentially fixed to the connecting seat 10, and the connecting seat 10 is fixed to the other end of the upper lock buckle 6. In this embodiment, the locking disc 9 and the connecting seat 10 are circumferentially fixed by polygonal fit or spline fit. For example, the locking disc 9 has a polygonal inner hole, and a part of the circumferential surface of the connecting seat 10 is a polygonal structure. The polygonal structure is combined with the polygonal inner hole to make the locking disc 9 and the connecting seat 10 circumferentially fixed.

[0027] A through hole 9a is provided on the axial end surface of the locking disk 9, and the other end of the rod-shaped component 7 is clearance-matched with the through hole 9a. When the locking disk 9 and the connecting seat 10 are circumferentially fixed, the clearance-matching between the rod-shaped component 7 and the through hole 9a is to limit the rotation of the locking disk 9. In this case, the connecting seat 10 is affected by the combination structure of the locking disk 9 and the rod-shaped component 7, and the connecting seat 10 cannot rotate. However, when the locking disk 9 is subjected to an axial force, the locking disk 9 moves along the axial direction of the connecting seat 10, thereby releasing the circumferential fixing structure of the locking disk 9 and the connecting seat 10. At this time, when a circumferential force is applied to the connecting seat 10, the connecting seat 10 can rotate.

[0028] The elastic component 8 is sleeved on the rod-shaped component 7, one end of the elastic component 8 is matched with the axial end face of the locking disk 9, and the other end of the elastic component 8 is matched with the rod-shaped component 7 or the movable seat 5. In this embodiment, the elastic component 8 is preferably a spring, one end of the elastic component 8 is pressed against the axial end face of the locking disk 9, and a shoulder is provided on the rod-shaped component 7, and the other end of the elastic component 8 is pressed against the shoulder on the rod-shaped component 7. When the locking disk 9 is subjected to axial pressure, the locking disk 9 transmits the pressure to the elastic component 8, compressing the elastic component 8, thereby providing space for the axial direction of the locking disk 9.

[0029] The pneumatic clamping device of this embodiment further includes a limiting column 11 for axially limiting the axial movement of the locking disk 9. One end of the limiting column 11 is fixed to the movable seat 5, and there is a gap between the other end of the limiting column 11 and the locking disk 9. When the locking disk 9 moves axially, the locking disk 9 compresses the elastic component 8. In order to avoid damage to the elastic component 8 caused by excessive compression, when the locking disk 9 and the limiting column 11 are in contact, the locking disk 9 cannot move further axially. At this time, the axial movement of the locking disk 9 reaches the maximum value.

[0030] The inflatable clamping device of this embodiment also includes a driving mechanism, which includes a pressing sleeve 12 and a driving unit 13. The pressing sleeve 12 is used to drive the locking 9 to move axially; the driving unit 13 is combined with the connecting seat 10 to drive the connecting seat 10 to rotate, and the driving unit 13 is rotatably matched with the inner hole 12a of the pressing sleeve 12.

[0031] A second polygonal protrusion 10a is provided on the circumferential surface of the connecting seat 10; a second limiting component 12c having a second polygonal inner hole 12b is provided in the inner hole 12a of the pressing sleeve 12, and the second polygonal inner hole 12b matches the second polygonal protrusion 10a. After the pressing sleeve 12 is put on the connecting seat 10, the driving unit 13 is combined with the connecting seat 10 to drive the connecting seat 10 to rotate, so that the second polygonal protrusion 10a and the second limiting component 12c form an axial limiting combination.

[0032] The driving unit 13 includes a driving rod and a driver connected to the driving rod. The driver can be a hydraulic cylinder or a pneumatic cylinder. When the driver is working, the driving rod is driven to rotate in the pressing sleeve 12. The connecting seat 10 is provided with a plug hole 10b, which is used to engage with the driving rod. In this embodiment, the driving rod is cut into a polygon, and the plug hole 10b is also a polygonal hole.

[0033] The working process of the utility model is as follows:

[0034] (1) The process of clamping the vulcanized tire A: Before clamping the tire, the structure consisting of the upper lock buckle 6, the movable seat 5, the rod-shaped component 7, the elastic component 8, the locking disc 9, the connecting seat 10 and the driving mechanism is lifted upward to separate the upper lock buckle 6 from the lower lock buckle 4 to make room, and the tire A is put on the lower clamping plate 2, and the pressing sleeve 12 is put on the connecting seat 10. At the same time, the pressing sleeve 12 applies a downward axial force to the locking disc 9, and the locking disc 9 compresses the elastic component 8 downward and moves axially downward. The circumferential fixing relationship between the locking disc 9 and the connecting seat 10 is released, and the driving rod in the driving unit 13 is inserted into the plug hole 10b on the connecting seat 10 to form a circumferential fixation. The driver works to drive the driving rod to rotate, which in turn drives the connecting seat 10 and the upper lock buckle 6 to rotate forward, and the connecting seat 1 0 after rotation, the second polygonal protrusion 10a on the connecting seat 10 and the second limiting component 12c on the pressing sleeve 12 are buckled with each other, and the structure composed of the upper lock buckle 6, the movable seat 5, the rod-shaped component 7, the elastic component 8, the locking disk 9, and the connecting seat 10 is moved as a whole through the driving mechanism, so that the upper lock buckle 6 passes through the first polygonal inner hole 4c, and the driver works to drive the driving rod to rotate, thereby driving the connecting seat 10 and the upper lock buckle 6 to rotate forward in turn. After the connecting seat 10 rotates, the second polygonal protrusion 10a on the connecting seat 10 and the second polygonal inner hole 12b on the pressing sleeve 12 form a matching relationship, and after the upper lock buckle 6 rotates, the first polygonal protrusion 6b abuts against the first step 4d, so that the upper lock buckle 6 and the lower lock buckle 4 form an axial limit combination, that is, they are buckled with each other (such as Figure 6 and 7 ), it can be seen from the above that, since the upper locking buckle 6 cannot move axially, the axial movement of the upper chuck 3 is also restricted, so the tire A is restricted between the lower chuck 2 and the upper chuck 3, and after the tire A is inflated, the tire A can be cooled and shaped. In the clamping state, since the second polygonal protrusion 10a on the connecting seat 10 forms a matching relationship with the second polygonal inner hole 12b on the pressing sleeve 12, the driving mechanism can be separated from the connecting seat 10, and the locking plate 9 is driven to move upward along the axial direction of the connecting seat 10 under the tension of the elastic component 8, so that the locking plate 9 and the connecting seat 10 are re-fixed in the circumferential direction to prevent the connecting seat 10 from rotating.

[0035] (2) Release the clamping of tire A: put the pressing sleeve 12 on the connecting seat 10, and at the same time, the pressing sleeve 12 applies a downward axial force to the locking plate 9, which compresses the elastic component 8 downward and moves axially downward. The circumferential fixing relationship between the locking plate 9 and the connecting seat 10 is released, and the driving rod in the driving unit 13 is inserted into the plug hole 10b on the connecting seat 10 to form a circumferential fixation. The driver works, driving the driving rod to rotate, and then driving the connecting seat 10 and the upper lock buckle 6 to rotate forward in turn. After the connecting seat 10 rotates, the second The polygonal protrusion 10a is engaged with the second limiting component 12c on the pressing sleeve 12, and after the upper lock buckle 6 rotates, the first polygonal protrusion 6b is released from the first step 4d. At this time, the first polygonal protrusion 6b rotates to a position matching the first polygonal inner hole 4c, and then a lifting force is applied to the connecting seat 10 through the driving mechanism, thereby lifting the structure composed of the upper lock buckle 6, the movable seat 5, the rod-shaped component 7, the elastic component 8, the locking disk 9, the connecting seat 10 and the driving mechanism upward, so that the upper lock buckle 6 is separated from the lower lock buckle 4.
