Abstract
The utility model discloses a locking mechanism, in particular a thread locking mechanism for a sliding body. The thread locking mechanism for the sliding body comprises a fixed body and the sliding body which can slide relative to the fixed body and is characterized in that the sliding body is provided with an oil cylinder connected with a hydraulic control device; the outer end of a piston rod in fit with the oil cylinder is connected with one end of a rotating board; the other end of the rotating plate is connected with a screw rod; the screw rod is in fit with a screw hole on the sliding body; a sliding block is arranged in a groove on the sliding body; and the end of the screw rod is pressed against a sliding surface of the fixed body by the sliding block. When the thread locking mechanism works, the oil cylinder is driven by a hydraulic drive device to make the piston rod axially move so as to drive the rotating plate to rotate a certain angle, then the screw rod rotates with the rotating plate and the end of the screw rod is pressed toward the fixed body by a pressing block so as to increase friction force between the screw rod and the fixed body and fulfill the locking aim. The thread locking mechanism for the sliding body has the advantages of simple integral structure, flexible and reliable operation, few components and low processing cost and is particularly suitable for light-duty locking.
Description
Technical field
The utility model relates to a kind of retaining mechanism, particularly a kind of screw-threaded coupling mechanism that is used for slide mass.
Background technology
The mechanism that often has slide mass to move with respect to fixed body in machining apparatus or other equipment, slide mass moves in slideway usually.When slide mass moves to a certain position, not only need to stop, but also need fixing and locking.Retaining mechanism adopts the mode of clamping mostly at present, needs comparatively complicated clamping device, and is not too suitable for light-duty locking.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, flexible movements are reliable, parts are few, cost is low, be suitable for the screw-threaded coupling mechanism that is used for slide mass of light-duty locking, overcome the deficiencies in the prior art.
The screw-threaded coupling mechanism that is used for slide mass of the present utility model, it comprises fixed body 1 and with respect to fixed body slide mass 2 slidably, it is characterized in that: on slide mass 2, be provided with the oil cylinder 11 that joins with hydraulic control device, the external end head of the piston rod 9 that matches with oil cylinder 11 is connected an end of flap 12, the other end of flap 12 and screw mandrel 4 join, screw mandrel 4 matches with the silk hole on the slide mass 2, be provided with sliding shoe 3 in the groove on slide mass 2, the termination of screw mandrel 4 leans on the sliding surface of fixed body 1 by sliding shoe 3.
The screw-threaded coupling mechanism that is used for slide mass of the present utility model, wherein said screw mandrel 4 is provided with external splines and matches with internal spline on the flap 12.
The screw-threaded coupling mechanism that is used for slide mass of the present utility model, the termination of wherein said piston rod 9 is connected to induction screw 7, is fixed with position sensor 5 and matches with induction screw 7 on slide mass 2.
The screw-threaded coupling mechanism that is used for slide mass of the present utility model, during work, oil cylinder moves axially piston rod under fluid pressure drive device drives, thereby driving flap turns an angle, screw mandrel rotates thereupon, and fixed body is pressed to by briquetting in the termination of screw mandrel, the frictional force between increase and the fixed body, reach the purpose of locking, overall structure is simple, and flexible movements are reliable, and parts are few, processing cost is low, is particularly suitable for light-duty locking.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is a schematic top plan view shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2: 1 is fixed body, and 2 is slide mass, and slide mass 2 with respect to fixed body 1 slidably, reaches the purpose that the drive miscellaneous part moves in slideway.Bolting has oil cylinder 11 on slide mass 2, and oil cylinder 11 joins with hydraulic control device, and the piston 10 in it connects piston rod 9, and the external end head of piston rod 9 and vertical direction are fixed with bearing pin 8, and lock shaft 8 matches with the slotted hole 13 of flap 12 1 ends.The endoporus of the other end of flap 12 is processed with internal spline, matches with the external splines on screw mandrel 4 tops.Screw mandrel 4 matches with the silk hole on the slide mass 2, and the crown, bottom of screw mandrel 4 leans against on the briquetting 3, and briquetting 3 is positioned at the groove on the slide mass 2.Briquetting 3 leans against on the sliding surface of fixed body 1.
Be threaded on the external end head of piston rod 9 and responded to screw 7, bolting has support 6 on the slide mass 2, is fixed with position sensor 5 and matches with induction screw 7 on support 6.
When slide mass 2 moves with respect to fixed body 1, oil cylinder 11, piston 10, piston rod 9, screw mandrel 4, briquetting 3, support 6 and position sensor 5 all move with slide mass 2, in the time of need stopping and locking, drive oil cylinder 11 work by hydraulic control device, piston rod 9 moves axially, driving flap 12 turns an angle, screw mandrel 4 is rotated thereupon, when screw mandrel 4 when it axially moves down, briquetting 3 is pressed to fixed body 1, increase frictional force, reached the purpose that stops and locking.Position sensor 5 joins with the control circuit that control slide mass 2 moves, and gathers during work and whether locks signal, thereby cooperate the control circuit work of slide mass 2.
