Abstract
The utility model discloses a lifting device, in particular a lifting device for a lifting positioner. The lifting device comprises a driving system (1), a lifting screw (2), a linear guide rail (3), a nut pair (4) and a slide seat (5), wherein the driving system (1) is connected with the nut pair (4) through the lifting screw (2); the slide seat (5) is fixed on the linear guide rail (3); and the side face of the slide seat (5) is hung and fastened to the nut pair (4) on two sides of the lifting device. The lifting device is characterized in that: a section of buffer area (6) extends from the lower part of the slide seat (5) hung and fastened to the nut pair (4); the nut pair (4) is provided with a proximity switch (7); and the proximity switch (7) and the driving system (1) are connected with the same control system. The lifting device has the advantages that: the section of buffer area is arranged between the nut pair and the slide seat, so that opposite force cannot be generated for the nut pair when a workpiece is contacted with an electric trolley, and the nut pair cannot be damaged.
Description
Technical field
The utility model relates to a kind of jacking system, is specifically related to a kind of jacking system of lifting mode positioner.
Background technology
We know that the elevating function of lifting mode positioner is led by line slideway, the drive systems elevating screw, and screw mandrel drive nut pair, pair of nut drives the slide lifting.
Because positioner just can stop descending motion with all dropping to workpiece can be placed on the electronic chassis after 180 ° of the workpiece upsets each time.In actual the use, contacting chassis and place steadily this process on chassis at workpiece, can form the reverse impact of workpiece to equipment, by the transmission of power, finally is that slide can produce opposite force to pair of nut, can cause badly damaged to equipment.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of jacking system of lifting mode positioner is provided, and has solved in the existing apparatus when descending the excessive problem that causes device damage of the opposite force of pair of nut.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
The jacking system of lifting mode positioner, comprise drive system, elevating screw, line slideway, pair of nut and slide, wherein drive system links to each other with pair of nut by elevating screw, slide is fixed on line slideway, and the side of slide buckles on the pair of nut of jacking system both sides, and slide buckles and extends one section buffer zone in the bottom of nut vice division chief, be equipped with on the pair of nut near switch, link to each other with same control system with drive system near switch.
Compared with prior art, the beneficial effects of the utility model are: set up one section buffer zone between pair of nut and slide, can not produce opposite force to pair of nut when workpiece is contacted with electronic chassis, make pair of nut can therefore not cause damage.
Description of drawings
Fig. 1 is the utility model local structure enlarged diagrams.
Fig. 2 is the structural representation of the utility model decline reference position.
Fig. 3 is the structural representation of the utility model decline critical spot.
Fig. 4 is the structural representation of the utility model decline end position.
Among the figure: 1 is drive system, and 2 is elevating screw, and 3 is line slideway, and 4 is pair of nut, and 5 is slide, and 6 is buffer zone, and 7 is near switch.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 2, the jacking system of lifting mode positioner, comprise drive system 1, elevating screw 2, line slideway 3, pair of nut 4 and slide 5, wherein drive system 1 links to each other with pair of nut 4 by elevating screw 2 as shown in Figure 1, slide 5 is fixed on the line slideway 3, the side of slide 5 buckles on the pair of nut 4 of jacking system both sides, pair of nut 4 is passed in the bottom of slide 5 sides one section buffer zone 6, be equipped with on the pair of nut 4 near switch 7, link to each other with same control system with drive system 1 near switch 7.
The structural representation of the jacking system reference position of this lifting mode positioner as shown in Figure 2, the lifting mode positioner begins to descend, arrive as shown in Figure 3 when positioner drops to workpiece 8 and just contacts electronic chassis 9, when pair of nut 4 is produced reverse impact, separate with the contact surface of slide 5 pair of nut 4 upper ends, this moment, pair of nut 4 can continue to descend, be placed on fully on the electronic chassis 9 until workpiece 8, sending signal near switch 7 behind certain distance as shown in Figure 4, positioner stops descending motion.
Claims (1)
1. the jacking system of lifting mode positioner, comprise drive system (1), elevating screw (2), line slideway (3), pair of nut (4) and slide (5), wherein drive system (1) links to each other with pair of nut (4) by elevating screw (2), slide (5) is fixed on line slideway (3), the side of slide (5) buckles on the pair of nut (4) of jacking system both sides, it is characterized in that: pair of nut (4) is passed in slide (5) bottom, side one section buffer zone (6), be equipped with on the pair of nut (4) near switch (7), link to each other with same control system with drive system (1) near switch (7).
