The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
The present invention is installed in an end of X ray lathe body, integrates a body power source and bed body position limitation protection.As shown in Figure 1, comprise moving component 1 and fixed structure piece 12, the bed body is connected on the moving component 1; One side direction of moving component 1 has projection 13, is positioned at the outside of fixed structure piece 12 sidewalls; Fixed structure piece 12 side arm inboards are provided with motor 19 and reductor 20, are connected with projection 13 on the moving component 1 by actuating device, and drive motion components 1 moves back and forth.The actuating device of present embodiment is a chain drive structure, drive sprocket 9 is installed on the fixed structure piece 12 with driven sprocket 26, drive sprocket 9 is connected with reductor 20, motor 19, motor 19 and reductor 20 are positioned at fixed structure piece 12, on the fixed structure piece 12, be welded with slave board 21 between reductor 20 and fixed structure piece 12.Drive sprocket 9 and driven sprocket 26 are connected with fixedly connected 5 by chain 8, and chain 8 is provided with adjusting yoke 6, and it passes fixedly connected 5 and is fixed on fixedly connected 5 by clamp nut 16.As Fig. 4, shown in Figure 5, fixed structure piece 12 is the U-shaped cavity, and intracavity is provided with transverse slat 27, is connected with line slideway 25 by second screw 23 on it, is connected with slide block 24 by first screw 22 on the moving component 1, is connected with line slideway 25 precision-fit.The precision-fit of slide block 24 and line slideway 25 had both increased the intensity of fixed structure piece 12, satisfied the support strength to moving component 1, had realized the rectilinearity that moving component 1 moves back and forth again effectively.Projection is connected with the first～three collision block 3,4,7 and fixedly connected 5 on 13, is provided with microswitch and dry-reed tube switch 17 on the running orbit of the outer wall surface of fixed structure piece 12 and protruding 13 homonymies, the first～three collision block 3,4,7.The number of microswitch is four, and first microswitch 11 plays the limit protection effect that moving component 1 moves to the right; Second microswitch 14 plays the position-limiting action that moving component 1 moves left; The 3rd microswitch 15 plays the position-limiting action that moving component 1 moves to the right; The 4th microswitch 18 plays the limit protection effect that moving component 1 moves left.Dry-reed tube switch 17 is between first microswitch 11 and the 4th microswitch 18; Second collision block 4 corresponding with dry-reed tube switch 17 correspondingly is installed between first collision block 3 and the 3rd collision block 7 or a side of the 3rd collision block 7, second collision block 4 of present embodiment is between first collision block 3 and the 3rd collision block 7, and dry-reed tube switch 17 is between the 3rd microswitch 15 and the 4th microswitch 18.On the outer surface of fixed structure piece 12 sidewalls, be positioned at projection 13 both sides and be provided with first and second mechanical position limitation 2,10, strictness has limited the traverse motion scope of moving component 1, can prevent that the slide block 24 under the moving component 1 is deviate under the situation of maloperation before actuating device is not installed from line slideway 25, guarantee that each parts is not damaged on operator's personal safety and the moving component 1.
Operation principle of the present invention is: motor 19 energising work drive drive sprocket 9 rotations through reductor 20.Drive sprocket 9 passes through chain 8 again through driven sprocket 26 transmissions, drives moving component 1 by fixedly connected 5 on the projection 13 and moves on line slideway 25, plays the power source effect of a body.When second collision block 4 passed through dry-reed tube switch 17, effect produced signal, realizes moving component 1 zero-point positioning, and the bed running body arrives the precalculated position.In service to the right at moving component 1, first collision block 3 runs to the 3rd microswitch 15 places, produces signal with its contact effect, and is spacing to moving component 1; If the 3rd microswitch 15 does not produce signal, moving component 1 continues operation to the right, and the 3rd collision block 7 runs to first microswitch, 11 places, produces signal with its contact effect, to moving component 1 limit protection.In service left at moving component 1, the 3rd collision block 7 runs to second microswitch, 14 places, produces signal with its contact effect, and is spacing to moving component 1; If second microswitch 14 does not produce signal, moving component 1 continues operation left, and first collision block 3 runs to the 4th microswitch 18 places, produces signal with its contact effect, to moving component 1 limit protection.The distance of first collision block, 3 to the 3rd microswitch, 15 contacts is less than the distance of the 3rd collision block 7 to first microswitch 11 contacts, optimum is 8mm, and two range differences are less than the distance of the 3rd microswitch 15 contacts to second microswitch, 14 contacts, after guaranteeing that first collision block 3 is through the 3rd microswitch 15, before no show second microswitch 14, the 3rd collision block 7 produces signal with the effect of the contact of first microswitch 11.Microswitch and dry-reed tube switch are commercial product, and volume is little, installation and removal are convenient, have realized arranging in less spatial dimension the design of multiple functional many switches.
The present invention integrates the power source and the limiting protecting bed board motor function of bed body motion, make compact overall structure, rationally distributed, processing is easy, cost is low.
