The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
As shown in Figure 1, pick is to the sample clamp device of rock cutting test, comprise mounting base, the Height Adjustment part of clamping fixture table 10 and clamping fixture table 10, grooved table top in the middle of described clamping fixture table 10 comprises and the shoulder of both sides, shoulder is v-shaped structure, the top of both sides shoulder all is provided with side direction fixture and vertical fixture, described side direction fixture comprises the lateral register frame 12 that is arranged at clamping fixture table two shoulders, lateral register frame 12 bottoms arrange the T shape slide rail of horizontal direction, 10 liang of shoulder tops of clamping fixture table are provided for installation side to the T-slot of the horizontal direction of locating rack 12T shape slide rail, the middle inside of lateral register frame 12 arranges side direction and clamps jacking block 17, lateral register frame 12 outsides are equipped with and act on the side direction fixed oil cylinder 14 that side direction clamps jacking block 17, described vertical fixture comprises the vertical fixed mount 13 that is arranged on the side direction fixed mount 12, vertical fixed mount 13 is inverted L-shaped, the T shape slide rail of vertical fixed mount 13 arranged outside vertical directions, lateral register frame inboard is provided with the T shape chute be used to the vertical direction that vertical fixed mount 13T shape slide rail is installed, vertical fixed mount 13 connects the vertical fixed oil cylinder 15 that drives its vertical motion, and the horizontal segment bottom of vertical fixed mount 13 arranges rubber blanket 16.
Such as Fig. 2, shown in 3, described Height Adjustment partly comprises drive motors 1, drive motors 1 connects worm type of reduction gearing 3 by shaft coupling 2, worm type of reduction gearing 3 connects drive sprocket, drive sprocket connects driven sprocket by driving-chain 11, drive sprocket and driven sprocket are installed in respectively on two threaded rods 9, the two ends of two threaded rods 9 are respectively the opposite screw thread of rotation direction, threaded rod 9 is fixed on the mounting base by bearing and bearing block, threaded rod 9 two ends have the position of the opposite screw thread of rotation direction that slide block 7 all is installed, slide block 7 passes through threaded engagement with threaded rod 9, two slide blocks, 9 tops on each threaded rod 9 are intilted slope, the slope, top of two slide blocks is slidingly matched with the two sides of the shoulder of clamping fixture table v-shaped structure bottom respectively on each threaded rod 9, slide block 9 bottoms also are provided with T shape slide rail, be provided with the T-slot that cooperates with slider bottom T shape slide rail on the mounting base, the middle part of two threaded rods 9 arranges spacing block, clamping fixture table also is connected with axial advance oil cylinder 18, and the action direction of axial advance oil cylinder 18 is parallel with the axis of threaded rod 9.
Drive motors is taken turns power distribution by the turbine and worm decelerator to a side chain, with on the powerdriven opposite side sprocket wheel, realize the mean allocation of power by chain.When drive motors rotated, chain-driving both sides threaded rod rotated synchronously, made slide block in the same way or reverse the movement.When slide block moved in the same way, the clamping fixture table that is installed in the slide block top rose; When slide block oppositely moved, the clamping fixture table that is installed in the slide block top descended, and reaches the purpose of adjusting workpiece mounting center height, and utilizes the turbine and worm decelerator to realize the auto-lock function of lifting platform height and position.
