The connecting shaft 43 is connected at the central part of placing the case 40, and the equal angle distribution on the connecting shaft 43 has the pushing plate 44, and the length of the pushing plate 44 is smaller than the radius of the inner space of placing the case 40, so that the pushing plate 44 can be ensured to drive the connecting shaft 43 to perform stable rotation work in the placing case 40, and further the stability of subsequent cooling work can be ensured.

The working principle is as follows: before the workpiece transfer device with the built-in preheating and cooling mechanism based on the five-axis machining center is used, the overall situation of the device needs to be checked firstly, and normal work can be determined;

when the device starts to work, with reference to fig. 1-5, the universal wheel 2 is used in combination, a worker can move the whole pushing device to a stable position, after a workpiece is machined on a machining center, the worker can push the whole device to the machining center, and then the worker can step down on the sliding plate 3, at this time, the sliding plate 3 performs stable limited sliding work on the device base 1, meanwhile, the sliding plate 3 can drive the baffle 33 on the side to move downwards, at this time, the baffle 33 can be pushed to rotate towards the left side under the action of the fixture block 35 on the fixing plate 34 on the right side of the sliding plate 3, then when the baffle 33 continues to move downwards and is separated from the fixture block 35, the baffle 33 can be restored to the original position in combination with the rubber block 32, at this time, the separated fixture block 35 can perform automatic and stable clamping and fixing work on the baffle 33, and further can effectively prevent the sliding plate 3 from moving upwards, at the moment, the first gear rack 5 can be driven to move downwards under the action of the sliding plate 3, so that the first circular gear 6 can be driven to stably engage and rotate, at the moment, the first circular gear 6 can drive the first bevel gears 8 on two sides to rotate through the fixed shaft 7, so that the first threaded rods 10 on the second bevel gears 9 on two sides can be driven to rotate in the supporting bases 11, at the moment, the first threaded rods 10 on two sides can drive the first threaded rods 10 to simultaneously rotate in the corresponding supporting bases 11 by combining with the driving belt 12, so that the supporting bases 11 can be conveniently and stably driven to simultaneously move downwards, the whole device is lifted up until the universal wheel 2 is separated from the ground, at the moment, the whole device can be stably placed, and the supporting height of the supporting bases 11 can be adjusted by adjusting the descending distance of treading the sliding plate 3, the use height of the whole device can be conveniently and stably adjusted;

and when the fixed shaft 7 rotates, with reference to fig. 1-3, 6 and 7, the first coil 13 on the fixed shaft 7 can rotate and wind the connecting wire 14, at this time, the connecting wire 14 in combination with the guide wheel 15 can drive the second coil 17 to stably rotate, and further can drive the second threaded rod 18 on the second coil 17 to stably rotate in the air-permeable mesh frame 16, at this time, under the rotation action of the second threaded rod 18, the placing mesh frame 20 fixedly connected can be pushed by the connecting sleeve rod 19 to stably move outwards in the air-permeable mesh frame 16, at this time, the protecting door plate 28 can be pushed to automatically open outwards under the pushing action of the placing mesh frame 20, when the sliding plate 3 stops moving, the fixed shaft 7 simultaneously stops moving, at this time, the placing mesh frame 20 can extend outwards to a workpiece in the machining center, and when the placing mesh frame 20 moves outwards, the second circular gear 22 can be driven to automatically open on the second wheel toothed rod 23 The second circular gears 22 on the two sides drive the connecting rods 24 on the corresponding rotating shafts 21 to move outwards at the same time, then the worker can push the workpiece to be placed on the placing screen frame 20, then the worker can continue to use the footsteps to push the baffle 33 to move upwards and separate from the fixture block 35, at the same time, the sliding plate 3 can move upwards and return to the original position under the action of the rubber rods 4, and further can drive the supporting base 11 to move upwards and return to the original position, meanwhile, the scroll spring 31 in the limiting frame 30 can drive the second threaded rod 18 to rotate reversely, and further can drive the placing screen frame 20 to move inwards to the air-permeable screen frame 16 and return to the original position, at the same time, the workpiece can be conveniently and quickly stored, and when the placing screen frame 20 moves, the second circular gears 22 on the placing screen frame 20 can drive the connecting rods 24 on the corresponding rotating shafts 21 to rotate inwards at the same time under the meshing action of the second gear rods 23, the rubber plates 26 on the mounting plates 25 on the two sides can be driven to simultaneously horizontally move towards the middle by combining with the corresponding dragging rods 27, so that the automatic clamping and limiting work of the workpiece can be conveniently and stably carried out, and at the moment, the protective door plate 28 can form a closing and closing work by combining with the rubber roller 29, so that the stability of the subsequent moving work can be ensured;

after the supporting base 11 is returned to the original position, with reference to fig. 1-6 and 8-10, the universal wheel 2 contacts with the ground, so as to drive the whole device and the workpiece to perform stable transportation, at this time, the worker can control to turn on the small water pump 41, at this time, under the action of the small water pump 41, the coolant in the placing box 40 can be conveyed to the placing box 40 through the cooling pipe 42 to complete the circulation of the coolant, and when the cooling pipe 42 conveys the coolant into the placing box 40, the pushing plate 44 can be driven to rotate under the impact of the coolant, so as to drive the exhaust fan 45 on the connecting shaft 43 to rotate, at this time, under the rotation of the exhaust fan 45, in combination with the cooling pipe 42, the processed workpiece can be cooled rapidly, effectively and uniformly, and in the same way, after the processed workpiece is placed in the placing area, the worker can place the workpiece to be machined in the apparatus, and can then transport the workpiece to the machining center, in the transferring process, a worker can control to open the electric heating pipe 36, at the moment, water in the storage pipe 37 can be evaporated to form steam under the heating action of the electric heating pipe 36, then the steam is conveyed to the fan blades of the guide fan blades 39 through the air guide pipes 38 on the storage pipe 37, thereby driving the guide vane 39 to rotate stably, and then the electric heating tube 36 and the steam can be combined to preheat the workpiece before processing on the screen frame 20 stably and uniformly under the rotation action of the guide vane 39, the above is the operation of the whole device, and details which are not described in detail in this specification, such as the universal wheel 2, the spiral spring 31, the electric heating pipe 36 and the small water pump 41, are well known to those skilled in the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
