Feature of the present invention, the one, realize the upper locking action that coils oscillating bearing by the hydraulic locking apparatus being formed by tubing spinning joint and lock sleeve, in control, dish becomes locked fixing from Universal active, reaches the function of plane of grinding wheel finishing; The 2nd, by being installed on the cooling water rotating joint of main shaft upper end, make cooling water can enter the cooling water channel between emery wheel and top tray, by upper dish is cooled, the accurate control of dish working stability in realization. The present invention can realize quick straight line finishing and the circulating cooling at place polishing grinding equipment, significantly improves working (machining) efficiency.
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Loading device for two-sided accurate grinding, grinding building-block machine provided by the invention, its structure as shown in Figure 1, comprise be located in frame by power-actuated upper main shaft 5, upper main shaft 5 is provided with belt pulley 16, belt pulley 16 is connected with spline housing 14 use bolts, spline housing 14 is connected in Pulley shaft bearing 13 with bearing 15, and Pulley shaft bearing 13 is fixed on the top 12 of frame; Upper main shaft 5 is supported in bearing block 10 by bearing 9, and bearing block 10 is fixed on the crossbeam 8 of frame; The top of described upper main shaft 5 is provided with tubing spinning joint 21 and water pipe swivel joint 19, and tubing spinning joint 21 excessively overlaps 20 by swivel joint and docks with the top of upper main shaft 5, and water pipe swivel joint 19 is installed on main shaft 5 tops around; The lower end of upper main shaft 5 is provided with the pallet 2 of fixing upper dish 1 by Universal active parts, described Universal active parts adopt oscillating bearing 3(or other universal ball end parts), oscillating bearing 3 is arranged in the dead eye of main shaft 5 lower ends, oscillating bearing 3 connects joint bearing block 4 by bearing pin, joint bearing block 4 is fixed by bolts on pallet 2, and pallet 2 is connected with upper dish 1 use bolt; Upper main shaft 5 is provided with axial cannelure, on the upper main shaft 5 between cannelure and joint bearing block 4, cover has lock sleeve 6, cannelure is by being located at the baffle plate 31 on described upper main shaft 5 and being threaded with baffle plate 31 and the oil scraper ring 7 that is enclosed within on lock sleeve 6 forms, between lock sleeve 6 and cannelure and upper main shaft 5, form seal oil chamber, seal oil chamber forms by forming the closed cavity 29 forming between upper oil chamber 30 and lock sleeve 6 and upper main shaft 5 between lock sleeve 6 and cannelure; In described upper main shaft 5, be provided with oil duct, oil duct comprises that the right-angled intersection that is positioned at the central oil passage 24 at main shaft 5 centers and be communicated with central oil passage 24 divides oil duct 28, in upper main shaft 5, be also provided with water channel, water channel comprises and is positioned at central oil passage 24 inlet channel 25, water outlet water channel 26 around and water inlet pipe 22, the outlet pipe 27 being communicated with inlet channel 25, water outlet water channel 26 respectively; Described tubing spinning joint 21 divides oil duct 28 to be communicated with described seal oil chamber by central oil passage and right-angled intersection, between described upper dish 1 and pallet 2, be provided with cooling water channel 23, described water pipe swivel joint 19 is communicated with the two ends of described cooling water channel 23 by inlet channel 25, water inlet pipe 22 and outlet pipe 27, water outlet water channel 26.
Motor power is delivered to spline housing 14 by belt pulley 16.
