Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a tire design vulcanizer capsule anchor clamps can effective silk hole frequently damage and the impaired tire mould anchor clamps fragile technical problem who causes of draw-in groove, improves tire mould anchor clamps's life, has reduced manufacturing cost.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1-4, the utility model provides a tire shaping vulcanizer capsule clamp, because the prior art (as shown in fig. 1) directly screws in the bolt hole, the stress of the bolt hole is concentrated, the condition of the thread disorder in the bolt hole is easy to occur; in order to solve the problem that the thread holes are prone to have the phenomenon of irregular teeth (shown in figure 2), the tire shaping vulcanizer capsule clamp is provided, and comprises a clamp body 1 and a main shaft 2 clamped in the middle by the clamp body 1, wherein two ends of the clamp body 1 are respectively provided with a first thread hole 11 for fixing a secondary steel ring 6, an internal thread fastener is screwed into the first thread hole 11, the thread pitch of the first thread hole 11 is larger than that of an internal thread of the internal thread fastener, the internal thread of the thread fastener is a standard M thread and is matched with a first bolt 12, and when the internal thread of the internal thread fastener is damaged, only the internal thread fastener needs to be replaced; aligning the threaded hole of the auxiliary steel ring 6 with the internal thread fastener, and screwing the first bolt 12 to tightly press the auxiliary steel ring 6; the chuck 3 and the clamping groove 9 are clamped in the prior art, the gasket 4 is connected to the chuck 3, then the second bolt 5 is screwed in for fixing, the scheme is adopted, the second threaded hole 7 is formed in the center line of the spindle 2, the circular blocking disc 8 bearing pressure is fixed above the second threaded hole 7, the circular blocking disc 8 is welded on the surface of the second threaded hole 7, and the clamping groove 9 is not stressed and is not easy to damage.

Specifically, in one embodiment of the present disclosure, to facilitate installation of the internally threaded fastener, the internally threaded fastener is a wire thread insert 10. Because the size of the messy teeth of the threaded hole is not controlled manually, when the external thread of the wire thread insert 10 is not matched with the internal thread of the first threaded hole 11, the wire thread insert 10 can be replaced by a self-made thread insert.

Specifically, in the above embodiment, in order to increase the strength of the wire thread insert 10, the material of the wire thread insert 10 is stainless steel.

Specifically, in one embodiment of the present disclosure, two first threaded holes 11 are arranged in a central symmetry manner of the fixture body 1; the positions of the threaded holes of the two random teeth may be asymmetric and have different sizes, but the first threaded holes 11 are the same in size and are symmetric with the center line of the clamp body 1.

Specifically, in an embodiment of the present disclosure, in order to enhance the strength of the whole structure, the thickness of the blocking disk 8 is the same as the height of the main shaft 2 extending out of the fixture body 1, that is, the upper end of the blocking disk 8 is on the same horizontal plane as the upper end of the main shaft 2.

Specifically, in the above-mentioned solution, in order to improve the strength of the catch plate 8, the catch plate 8 is made of stainless steel.

When the tire vulcanization fixture works, the sealing of the bladder is completed by the cooperation of the fixture body 1 and the auxiliary steel ring 6, and the threaded hole is easy to break the teeth and release due to the fact that the bladder is difficult to seal due to high pressure; according to the scheme, a new first threaded hole 11 is formed by reaming the threaded hole of the damaged clamp body 1, the first threaded hole 11 is screwed with the steel wire thread insert 10, the first bolt 12 is matched with the steel wire thread insert 10 to clamp the auxiliary steel ring 6, and when the steel wire thread insert 10 is damaged, only the steel wire thread insert 10 needs to be replaced; a circular blocking disc 8 is welded above the second threaded hole 7, the blocking disc 8 is not in contact with the clamping groove 9, the clamping groove 9 is not stressed, and therefore the clamping groove 9 is not easy to damage.

The utility model discloses a concrete example is applied to explain the principle and the implementation mode of the utility model, and the explanation of the above example is only used to help understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope.
