Description
Technical field
This utility model belongs to machine tool accessories technical field, is specifically related to a kind of Linear guide rail locking device.
Background technology
The Ministry of Industry and Information Technology has issued a standard, and standard No. is JB/T7175.1-2011, entitled " linear rolling guide
Part 1: term and symbol ", describe a kind of linear rolling guide, be made up of line slideway and slide block, as linear movement guide and the parts of supporting.The cross section of line slideway has given shape, there is one or more longitudinal raceway, installing hole is had on line slideway, can be screwed hole, usually blind hole, be arranged on the mounting plane of line slideway, it can also be cylindricality counter sink, countersunk head is positioned in the plane matched with slide block, linearly can arrange string in guide rail direction, it is also possible to arrange two row.Slide block is made up of slide body, rolling element, reverser and sealing member etc., it it is the assembly of linearly guide rail motion, mounting plane is arranged at slide block top, workpiece is linked together by joint bolt and this mounting plane, and two adjacent with mounting plane and parallel with line slideway direction planes are sides.
Motion accuracy of rolling lincar guide pair is high, easy care, service life is long, easy to use, can bear the directive load of institute in addition to direction along ng a path and torque with standardized production, in order to meet the needs of production, research worker designs again various Deformation mode, so using widely, is used in all trades and professions in national product.
In the case of Hen Duo, linear rolling guide and motor or servomotor support the use, line slideway is arranged in frame, workpiece is arranged on slide block, nut is had again on workpiece, leading screw and nut composition screw thread pair, motor or servomotor are fixed in frame, its spindle nose and leading screw couple, motor or servomotor can drive screw turns when rotating, workpiece linearly guide rail direction is driven to translate by screw thread pair, motor or servomotor self have lock function, after locking, leading screw is not rotated further by, the position of workpiece is also fixed.Some situations are changed the motor of such scheme and are made handwheel, and leading screw and frame are coupled by revolute pair, rotate handwheel and workpiece also can be driven to rotate, and time static, the auto-lock function by screw thread pair makes workpiece fix.
But also there are some operating mode linear rolling guides discord handwheel, motor or servomotor to support the use.Line slideway is arranged in frame, workpiece is arranged on slide block, there is no other joining parts, at this moment if it is desired to make the position of workpiece fix, other mechanism, the such as combinative structure of latch-pin hole, holding screw-fixed structure etc. can only be set on workpiece specially, add design time, manufacturing cost, also do not have research worker to attempt on slide block and retaining mechanism is set.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, it is provided that a kind of energy is convenient, accurately and reliably lock the Linear guide rail locking device of line slideway.
This utility model is achieved through the following technical solutions:
A kind of Linear guide rail locking device, including shell, cylinder, lock-screw and backing plate；The slide block of shell and line slideway auxiliary connects by connecting plate is fixing；Having circular hole and shell draw-in groove in the middle of shell, cylinder has external cylindrical surface, external cylindrical surface to form matched in clearance with circular hole, cylinder has cylinder draw-in groove and screwed hole；Line slideway is positioned at shell draw-in groove and cylinder draw-in groove, two backing plates lay respectively between two groove edges of cylinder draw-in groove and line slideway, and lock-screw forms screw thread pair with screwed hole, and lock-screw compresses backing plate, line slideway held tightly by two backing plates, finally makes slide block be firmly fixed together with line slideway.When needing the position adjusting slide block, it is only necessary to unscrew lock-screw, backing plate releases and holds line slideway tightly, it is possible to easily move slide block, after moving to the position of new needs, then screw lock-screw, then slide block fixedly secures again in new position.
Backing plate generally uses the material softer than steel, such as copper alloy or aluminium alloy, both will not weigh the surface of line slideway wounded, the biggest deformation will not occur again.
Above-described external cylindrical surface forms matched in clearance with the circular hole of shell, referring to tolerance fit H8/f7, H8/g7, H7/f6 or H7/g6, these tolerance clearances coordinate, and cylinder can be made to move freely in circular hole, the most do not have the biggest shaking volume, most service precision requirement can be met.Tolerance fit refers to the tolerance fit defined in GB/T 1800.2-1998.
The beneficial effects of the utility model: easy to use, accurately and reliably, simple in construction, make low cost.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Embodiment: see Fig. 1 to Fig. 6.
A kind of Linear guide rail locking device, including shell 1, cylinder 2, lock-screw 3 and backing plate 4；The slide block 5 of shell 1 and line slideway auxiliary connects by connecting plate 7 is fixing；Having circular hole 11 and shell draw-in groove 12 in the middle of shell 1, cylinder 2 has external cylindrical surface, external cylindrical surface to form matched in clearance with the circular hole 11 in shell 1, cylinder has cylinder draw-in groove 22 and screwed hole 21；Line slideway 6 is positioned at shell draw-in groove 12 and cylinder draw-in groove 22, two backing plates 4 lay respectively between 22 two groove edges of cylinder draw-in groove and line slideway 4, lock-screw 3 and screwed hole 21 form screw thread pair, lock-screw 3 compresses backing plate 4, line slideway 6 held tightly by two backing plates 4, finally makes slide block 5 be firmly fixed together with line slideway 6.When needing the position adjusting slide block 5, it is only necessary to unscrew lock-screw 3, backing plate 4 releases and holds line slideway 6 tightly, it is possible to the most mobile slide block 5, after moving to the position of new needs, then screws lock-screw 3, then slide block 5 fixedly secures again in new position.
Backing plate 4 generally uses the material softer than steel, such as copper alloy or aluminium alloy, both will not weigh the surface of line slideway 6 wounded, the biggest deformation will not occur again.
Above-described external cylindrical surface forms matched in clearance with the circular hole of shell, refer to tolerance fit H8/f7, H8/g7, H7/f6 or H7/g6, these tolerance clearances coordinate, cylinder 2 can be made to move freely in circular hole 11, the most do not have the biggest shaking volume, most service precision requirement can be met.Tolerance fit refers to the tolerance fit defined in GB/T 1800.2-1998.
The beneficial effect of the present embodiment: easy to use, accurately and reliably, simple in construction, make low cost.
