Abstract
The invention relates to a tool for detecting aging of a tire rubber piece with low rolling resistance. The tool comprises a bracket, elastic mechanisms and a stretching mechanism, wherein the bracket jointly consists of permanent seats which are transversely arranged and guide rods which are longitudinally arranged, wherein two permanent seats are arranged and a plurality of guide rods are sequentially distributed between the two permanent seats along the long axis directions of the permanent seats; through holes through which the guide rods pass are formed in the two permanent seats; the guide rods are movably connected with the elastic mechanism A which can be driven by the stretching mechanism to reciprocate along the long axis directions of the permanent seats, and the elastic mechanism B is fixedly connected to one of the permanent seats. The tool provided by the invention has the advantages that by virtue of the device, the rubber piece is compressed by using a bolt and meanwhile, the fixing mode of the bolt and a nut is stronger than a clamping force of a clip, so that the rubber piece can be better fixed; meanwhile, the stretching length of the rubber piece is directly adjusted by virtue of the stretching mechanism during stretching, so that the tool is very convenient.
Description
Technical field
The present invention relates to a kind of detection frock, particularly a kind of low rolling resistance tyre film ageing management frock.
Background technology
Tire is the annular elastic rubber product rolled at various vehicle or the ground connection of mechanically assembling.Usually be arranged in alloy rim, can vehicle body be supported, buffering foreign impacts, realize with the contact on road surface and ensure the rideability of vehicle.Tire is everlasting under complicated and exacting terms and is used, and it subjects various distortion, load, power and high/low temperature effect in motion, therefore must have higher load-carrying properties, hauling ability, shock-absorbing capacity.Meanwhile, also require to possess high-wearing feature and flexible resistance, and low resistance to rolling and heat generation.The half that the world consumes rubber mass is used for tire production, and visible tire consumes the ability of rubber.
Tire manufacturing process comprises: banburying operation---glue component preparatory process---tire building operation---vulcanization process---final inspection operation---Tire testing, wherein glue component preparatory process comprise again extrude, roll, tyre bead is shaping, cord severing, paste apex strip, shaping six workshop sections of belt.Wherein need to detect the aging rebound performance of film in glue component preparatory process, traditional method utilizes two clips to clamp the both sides of film, then after utilizing clip that film is stretched to certain length, after putting into baking oven heating a period of time, take out film, and decontrol clip, see that its distance that can bounce back is to judge its aging rebound performance.But staff finds in whole process, when utilizing clip to clamp film, because the pretightning force of clip is inadequate, just unclamped in film ageing process, causing cannot Measurement accuracy snap-off-distance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low rolling resistance tyre film ageing management frock that can be good at being clamped by film.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of low rolling resistance tyre film ageing management frock, and its innovative point is: comprise support, elastic mechanism and drawing mechanism;
Described support is made up of jointly the holder of horizontally set and the guide pole of longitudinally setting, described holder one has two, described guide pole has several, long axis direction along holder is distributed between two holders successively, and on two holders, have the through hole holding guide pole and pass, be connected with elastic mechanism A on the guide bar, and this elastic mechanism A can drive the long axis direction along guide pole to move back and forth by drawing mechanism, a holder is fixedly connected with elastic mechanism B wherein.
Further, described elastic mechanism A comprises Connection Block, tightening nut A and elasticity bolt A, described Connection Block is sleeved on the outer wall of all guide poles, and and be slidably connected between guide pole, at Connection Block fixed installation tightening nut A, and between tightening nut A and Connection Block, leaving the gap holding film and embed, described elasticity bolt A and tightening nut B cooperatively interacts and locks film; Described drawing mechanism comprise stretching screw mandrel and with stretching screw mandrel with the use of stretching nut, Connection Block and another holder all have the tapped through hole that an appearance stretching screw mandrel passes, and stretching screw mandrel is fixed by stretching nut through after Connection Block, described stretching screw mandrel is connected with stretching nut through after holder, and drives Connection Block to move back and forth by rotating stretching nut.
Further, described drawing mechanism B comprises tightening nut B and elasticity bolt B, tightening nut B to be fixed on holder and between tightening nut B and holder, to leave the gap holding film and embed, and described elasticity bolt B and tightening nut B cooperatively interacts and locks film.
Further, the two ends of described guide pole are threaded with between holder, and fix with locking nut screwing.
The invention has the advantages that: by this device, utilize bolt to be compressed by film, the fixed form of bolts and nuts is better than the clamping force of clip simultaneously, therefore, it is possible to well film is fixed, simultaneously when stretching, directly adjusted the tensile elongation of film by drawing mechanism, very convenient; By arranging multiple guide pole, multiple film can be placed simultaneously and carry out burn-in test, and often organizing film can also contrast; By being threaded with between holder at the two ends of guide pole, overall dismounting can be facilitated, maintenance.
Accompanying drawing explanation
Fig. 1 is the vertical view of low rolling resistance tyre film ageing management frock of the present invention.
Embodiment
Schematic diagram is as shown in Figure 1 known, and low rolling resistance tyre film ageing management frock of the present invention comprises support, elastic mechanism and drawing mechanism.
Form holder one has two to the guide pole 4 that support is arranged by holder and the longitudinal direction of horizontally set jointly, be respectively holder A2 and holder B9, guide pole 4 has several, long axis direction along holder is distributed between holder A2 and holder B9 successively, and on holder A2 and holder B9, have the through hole holding guide pole 4 and pass, guide pole 4 is connected with elastic mechanism A, and this elastic mechanism A can drive the long axis direction along guide pole 4 to move back and forth by drawing mechanism, holder A2 is fixedly connected with elastic mechanism B wherein.
The two ends of guide pole 4 are threaded with between holder A2 and holder B9, and tighten fixing with set nut 1 respectively.By being threaded with between holder A2 and holder B9 at the two ends of guide pole 4, overall dismounting can be facilitated, maintenance.
Elastic mechanism A comprises Connection Block 6, tightening nut A5 and elasticity bolt A, Connection Block 6 is sleeved on the outer wall of all guide poles 4, and and be slidably connected between guide pole 4, Connection Block 6 fixedly mounts tightening nut A5, and between tightening nut A5 and Connection Block 6, leaving the gap holding film and embed, elasticity bolt A and tightening nut A5 cooperatively interacts and locks film.
Drawing mechanism comprise stretching screw mandrel 8 and with stretching screw mandrel 8 with the use of stretching nut 8, Connection Block 6 and holder B9 all have the tapped through hole that an appearance stretching screw mandrel 8 passes, and stretching screw mandrel 8 is fixed by stretching nut A7 through after Connection Block 6, stretching screw mandrel 8 is connected with stretching nut B10 through after holder B9, and drives Connection Block 6 to move back and forth by rotating stretching nut B10.
