Detailed Description
The invention will be further described with reference to the accompanying drawings, which are provided for illustration of specific embodiments of the invention only and are not to be construed as limiting the invention in any way, the specific embodiments being as follows:
example 1
As shown in fig. 1 and with reference to fig. 2, a quick-change curing bladder clamping device comprises a clamping member 1, a pressing member 2, a curing bladder 3 and a fixing member 4. The curing bladder 3 is a structure with a cavity inside and two open ends, and comprises an annular curing bladder edge strip 301 and a curing bladder body 302. Vulcanization capsule strake 301 sets up in 3 open-ended edges of vulcanization capsule, the fixed of convenient vulcanization capsule 3.
The pressing piece 2 comprises an annular pressing groove 201, a buckling groove 202, a pressing main body 203 and a pressing slideway 205. The pressing slideway 205 is arranged on the pressing main body 203 and is of an annular structure with an opening on the outer periphery and a single side. The fastening groove 202 is disposed on the pressing body 203, and is in axial direction of the pressing chute 205 and communicated therewith.
The clamping piece 1 comprises a clamping body 102, a clamping tooth 103 and an annular clamping groove 101. The clamping groove 101 has the same structure as the pressing groove 201, and the opening direction is opposite to the opening direction, so that the clamping groove is adapted to the curing bladder edge strip 301. The clamping groove 101 is matched with the outer side face of the curing capsule edge strip 301, and the pressing groove 201 is matched with the inner side face of the curing capsule edge strip 301, so that the curing capsule edge strip 301 is clamped and fixed in a cavity formed by matching the clamping groove 101 and the pressing groove 201. The clamping main body 102 is of a circular ring structure, and at least 2 clamping teeth 103 are fixedly arranged on an inner ring of the clamping main body 102. Preferably, the clamping tooth 103 has multiple pieces, disposed along the circumferential direction of the inner race of the clamping body 102. The clamping teeth 103 can improve the matching strength of the clamping piece 1 and the pressing piece 2, and prevent the clamping piece 1 and the pressing piece 2 from deforming under larger pressure. The clamping teeth 103 are adapted to the snap-together slots 202 such that the clamping teeth 103 can pass through the snap-together slots 202 and into the compression chute 205. The clamping teeth 103 are adapted to the pressure slide 205 and can slide along the surface of the pressure slide 205.
The fixing piece 4 penetrates through the clamping piece 1 and the clamping teeth 103 to be connected with the pressing piece 2, and the clamping piece 1 and the pressing piece 2 are prevented from rotating relatively. The fixing member 4 is preferably a fixing rod having a screw thread, and is screw-coupled with the pressing member 2. The clamping piece 1 is placed in the pressing slide 205 of the pressing piece 2 by means of the clamping teeth 103, so that the fixation of the vulcanization capsule 3 is realized, and the phenomenon of looseness caused by the continuous tensioning and shrinkage alternation of the vulcanization capsule 3 is effectively prevented. The fixing member 4 can prevent the clamping member 1 and the pressing member 2 from relatively rotating, and further prevent the curing bladder 3 from loosening.
When the clamping device is used, the curing capsule edge strip 301 is pressed into the pressing groove 201, the clamping teeth 103 are placed into the pressing slide ways 205 through the fastening grooves 202, the clamping teeth 103 rotate for a certain angle, the fixing part 4 penetrates through the clamping teeth 103 and the pressing main body 203 corresponding to the clamping teeth 103, and therefore the clamping part 1 and the pressing part 2 are prevented from rotating relatively. Meanwhile, the edge strips 301 of the curing capsule are fixed by means of the matching action of the clamping grooves 101 and the pressing grooves 201. When the curing capsule 3 needs to be disassembled, the fixing piece 4 is disassembled, and the clamping piece 1 is rotated to the position corresponding to the buckling groove 202, so that the clamping piece 1 is separated from the pressing piece 2, and the curing capsule 3 is disassembled.
Example 2
A quick-change type curing bladder clamping device structure is the same as that in embodiment 1, except that:
as shown in fig. 3, the fixing member 4 penetrates through the portion of the pressing body 203 corresponding to the position of the clamping tooth 103 to be connected with the clamping tooth 103, so as to prevent the clamping member 1 and the pressing member 2 from rotating relatively.
Specifically, as shown in fig. 4, the clamping tooth 103 is integrally formed with the clamping body 102. The clamping tooth 103 is a wedge-shaped structure including a slip-off prevention groove 104 and a clamping tooth surface 105. The anti-slip groove 104 is a wedge-shaped groove structure with a single opening, and the opening surface of the wedge-shaped groove structure is overlapped with the clamping tooth surface 105. The position of the anti-falling groove 104 is matched with the position of the fixing piece 4, and the fixing piece 4 extends into the anti-falling groove 104 and is fixedly connected with the clamping teeth 103.
As shown in fig. 5 and with reference to fig. 6, the anti-slip groove 104 includes an anti-slip surface 106. The plane of the slip-off preventing surface 106 intersects the plane of the clamping tooth surface 105, that is, the slip-off preventing surface 106 has a certain inclination angle with respect to the clamping tooth surface 105.
As shown in fig. 6, the pressing chute 205 includes a wedge-shaped pressing block 204 therein, and the pressing block 204 includes a pressing surface (not shown) having an inclined surface. The pressing surface is arranged parallel to the clamping tooth surface 105, and after the clamping tooth 103 rotates to a certain position, the clamping tooth surface 105 can be in close contact with the pressing surface. By means of the compression block 204. The interact of pressing from both sides tight tooth 103 can be with the fixed inseparabler of curing bladder strake 301, improve the fastness and the leakproofness of curing bladder strake 301. The slip-off prevention surface 106 is located on the same side of the clamping tooth surface 105 as the vertical plane of the slideway surface of the pressure slide 205. The fixing part 4 interacts with the anti-loosening surface 106, so that a force for preventing the clamping part 1 and the pressing part 2 from loosening in a rotating mode can be generated, and the phenomenon that the clamping part 1 and the pressing part 2 loosen due to continuous tensioning and shrinkage alternation of the curing bladder 3 is further avoided.
The principle of the invention is as follows: the clamping piece 1 with the clamping groove 101 is placed into the pressing slideway 205 with the pressing piece 2 with the pressing groove 201 by means of the clamping tooth 103 and rotationally clamped, so that the fixing of the clamping piece 1 and the pressing piece 2 to the curing capsule 3 is realized. The fixing part 4 penetrates through the pressing part 2 and extends into the anti-falling groove 104 to press the anti-falling face 106, the interaction between the fixing part 4 and the anti-falling face 106 generates an acting force opposite to the pressing face and the clamping tooth face 105 of the pressing block 204 along the pressing slideway 205, self-locking is realized, the mutual rotation of the clamping part 1 and the pressing part 2 is further effectively prevented, and the fixing stability of the vulcanizing capsule 3 is ensured.
Thus, it should be understood by those skilled in the art that while exemplary embodiments of the present invention have been illustrated and described in detail herein, many other variations or modifications which are consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
