Abstract
The utility model relates to equipment for machining a tire semi-finished product and particularly relates to a device for perforating a tire blank of the tire semi-finished product. The device comprises a framework. A reducing box is arranged in the framework. A perforating pin rotation driving motor is matched with the upper part of the reducing box, and a transmission shaft is matched with the lower part of the reducing box. A perforating pin is matched with the lower part of the transmission shaft, and a perforating pin lifting air cylinder is arranged at the upper part of the framework. The device disclosed by the utility model is characterized in that the perforating pin and the transmission shaft are in clearance fit; the clearance fit means that a through hole passing through a shaft core is arranged in a radial direction at the bottom of a rotating shaft hole, the through hole is matched with a perforating pin fastening bolt and the fastening bolt is matched with a nut. The device disclosed by the utility model is simple and unique in structure, and can be used for avoiding the fault and hidden danger that the tire blank is damaged when a drilling and clamping head falls off. Meanwhile, the maintenance cost for purchasing the drilling and clamping head is saved.
Description
Technical field
The utility model relates to the half-finished equipment of a kind of processing tire, especially relates to a kind of tire semi-finished product tire base thorn eye device.
Background technology
In tire manufacturing processing technic flow process, the green tyre of machine-shaping is when getting into last one vulcanization process.For reducing the bubble that retains in the tire base to greatest extent, implement dazzlingly to green tyre, be to accomplish to the dazzling operation of green tyre by the dazzling machine of tire base.Existing dazzling machine pricker is to be connected through the power transmission shaft that pushes away handle drill chuck head and reduction box with the connecting mode of reduction box.Since when operation reduction box the rotary inertia that produces when rotating of vibrations with drill chuck head, cause power transmission shaft to push away the handle wearing and tearing, push away to connect between handle and drill chuck head and become flexible, drill chuck head comes off from the power transmission shaft of reduction box in rotation and injures the tire base.Simultaneously dazzling because be that a plurality of prickers carry out simultaneously, for guaranteeing dazzling quality, also for the balance of dazzling machine body self.All prickers can not push away the handle drill chuck head and will use left-handed and two kinds of models of dextrorotation to same direction rotation accordingly.Increased the deposit difficulty of spare part.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, a kind of uniqueness simple in structure is provided, can have thoroughly eliminated drill chuck head and come off and injure the potential faults of tire base, saved the tire semi-finished product tire base thorn eye device of the maintenance cost of buying drill chuck head simultaneously.
The utility model is realized through following mode:
A kind of tire semi-finished product tire base thorn eye device; It comprises a framework, is provided with reduction box in the framework, and reduction box top is combined with the pricker rotational drive motor; The bottom is combined with power transmission shaft; The bottom of power transmission shaft is combined with pricker, and the top of framework is provided with thorn needle lifting reservoir, and it is characterized in that: said pricker and said power transmission shaft form through matched in clearance;
Said matched in clearance is combined with the pricker fastening bolt for to cross a core diameter to making a call to a through hole in the bottom of said rotational axis hole on the through hole, be combined with nut on the fastening bolt;
Between said fastening bolt and nut, be combined with plain cushion and spring pad.
The utility model has following effect:
1) simple in structure, unique: it comprises a framework device that the utility model provides; Be provided with reduction box in the framework; Reduction box top is combined with the pricker rotational drive motor, and the bottom is combined with power transmission shaft, and the bottom of power transmission shaft is combined with pricker; The top of framework is provided with thorn needle lifting reservoir, and it is characterized in that: said pricker and said power transmission shaft form through matched in clearance; Said matched in clearance is combined with the pricker fastening bolt for to cross a core diameter to making a call to a through hole in the bottom of said rotational axis hole on the through hole, be combined with nut on the fastening bolt.
2) thoroughly eliminated drill chuck head and come off and injure the potential faults of tire base, saved the maintenance cost of buying drill chuck head simultaneously: the device that the utility model provides is that the middle coupling arrangement drill chuck head with existing pricker and reduction box shaft takes down.Overstriking lengthening reduction box power transmission shaft.Pricker directly connects with the reduction box power transmission shaft, and the axial punching at turning cylinder and pricker union end is used for putting into pricker.Pricker and transmission axis hole adopt matched in clearance.Be fixed lancet; Cross a core diameter in the bottom of rotational axis hole to the punching through hole; With the bolt of a diameter tip less than turning cylinder radial direction through hole diameter, make a call to the through hole that a diameter is a bit larger tham pricker tail end diameter in the bolt axle center of radially crossing of bolt, bolt is penetrated in the power transmission shaft hole radially; Insert pricker in the hole of power transmission shaft at last and pass the radial hole of bolt, add plain cushion, spring pad, nut at an end of bolt.Turn nut and make bolt produce radial displacement,, be convenient to the replacing and the maintenance of pricker with this mode fixed lancet of bolt and nut through the effect that the shearing force that pricker is applied reaches fixed lancet that moves radially of bolt with respect to power transmission shaft.Thoroughly having eliminated drill chuck head comes off and injures the potential faults of tire base.Saved the maintenance cost of buying drill chuck head simultaneously.
