Description

A kind of fixed device of Novel special-shaped

Technical field:

The utility model relates to the processing of sheet parts and low clearance cavity part, and in particular to a kind of Novel special-shaped is solid Determine device.

Background technique:

The lid plate parts of machinery industry and low clearance class cavity part, generally use vacuum chuck be adsorbed on workbench and Hydraulic vice is processed after clamping, but with the development of company, the structure diversification of Products is also same to part requirements Sample has been improved, and common installation way cannot adapt to nowadays processing request completely, has seriously affected processing efficiency and technique mark Standard increases technical costs.If the coverplate parts first upper pincers worker drilling again after number rushes to processing and then upper sucker suction milling, adds Work difficulty improves, low clearance cavity part clamps disadvantage there are two millings: 1, hydraulic vice external force directly on hydraulic vice Part deformation is caused greatly, influences dimensional accuracy；It 2, is appearance there may be clamping face for the part reprocessed, due to being appearance Face does not allow to clamp, or also needs to be surface-treated again after clamping, then improves product cost in this way.

Utility model content:

The utility model is a kind of novel fixed thinking, solves the fixed processing work low efficiency of cover board class and element precision is poor The shortcomings that.In addition, surface quality problems caused by solution hydraulic vice is excessive to part clamping force and clamping force difference are made At part deformation inconsistence problems.

The technical solution is a kind of fixed device of Novel special-shaped, including fixed device and locking device；The fixed device Including fixed station panel, button block；Parts to be processed is lain against above the fixed station panel, is offered on the fixed station panel Button block hole, the button block are inserted into the button block hole downward from the top of the fixed station panel, the position of the button block part Above the fixed station panel, it is positioned partially at the fixed station below the panel；The button block is located at the fixed station panel At least part of top positioned at parts to be processed in the part of top；The locking device includes steel wire and tension device；It is described Steel wire one end is connected to the part that the button block is located at the fixed station below the panel, and link position is the first tie point；One end It is connected to the tension device, link position is the second tie point；The height of second tie point is lower than first connection The height of point.

Its technical principle is: the existing method of clamping to sheet parts, low clearance cavity part is directly hydraulic It is clamped on vice, hydraulic vice external force, which will cause part deformation, influences the dimensional accuracy of part.Alternatively, reprocessing product for clamping Face requirement is excessively high, or the part being surface-treated does not allow to clamp, if it will cause appearance problems for clamping.This Shen Part please is placed on fixed station panel, and button block hole is offered on fixed station panel；Button block passes through button block hole, and a part is located at On fixed station panel, a part is located under fixed station panel, wherein the button block part being located above fixed station panel can be by zero Part is pressed on fixed station panel.Button block Clamp blocks are to be accomplished by the following way, and button block passes through fixed station panel, are located at and fix It is attached partially to steel wire below deck plate, the other end of steel wire is connected to locking device, and locking device applies downward steel wire The pulling force of side.When taut wire, button block is by past drop-down, so that button block is closely pressed on fixed station panel；Loosening steel wire When then button block unclamp, convenient for removing part.By adjusting the fixation dynamics of the adjustable part of steel wire pulling force, different fixed forces Degree is adapted to different processing methods.Make clamping in this way, due to clip position sheet part plane rather than side Face, can to avoid mode lower thin sheet class part, low clearance cavity part side chucking power it is excessive caused by deformation the shortcomings that.For Side is that appearance reprocesses part, moreover it is possible to prevent appearance clamped, solve the disadvantage that sheet parts are bad and reprocess.

Further, the fixed device further includes vice, and the vice is installed on platen；The fixed station Panel is fixed between the jaw of the vice；The tension device is fixed on the platen.

Further, the quantity in the button block hole is multiple, and the quantity of the button block is identical as the button block hole number.It is more A button block is conducive to increase holding area and clamping force, reduces local deformation.

Further, the tension device includes T-bar, the first locking nut, the first adjusting nut, locking member, second Locking nut；The T-bar is the screw rod with head, and the head of the T-bar is inserted into the T-slot of platen, The screw rod of the T-bar is perpendicular to the platen；First locking nut, the first adjusting nut, locking member, second Locking nut is successively screwed on the screw rod of the T-bar；Circumferential winding slot is set on the outer surface of the locking member, it is described The groove width of winding slot is greater than the gauge of wire, and the steel wire drops into the winding slot simultaneously after the extension of the first tie point It is wound around the locking member.Setting T-bar is conducive to for tension device being fixed on platen, and the first adjusting nut is arranged Be conducive to adjust the height gap between locking member and button block；And winding slot is set, so that steel wire drops into winding slot, it is convenient for Steel wire is tensioned, prevents steel wire from sliding on locking member.

Further, fixing threaded hole is set on the outer surface of the locking member, further includes solid with fixing threaded hole cooperation Determine bolt, the steel wire is wound onto after the locking member, and the end of the steel wire is crushed on the head of the fixing bolt It is fixed between the locking member.

Further, the button block quantity is multiple, and the quantity of the winding slot corresponds to the quantity of the button block, multiple The winding slot is alternatively arranged in the axial direction.

The beneficial effect of the utility model is:

1, it improves low clearance cavity part processing work efficiency and reduces mismachining tolerance, reduce the difficult processing of lid plate parts Degree, and solve the problems, such as that the clamping of repair piece causes to be deformed；

2, the fixation device of the utility model can adjust the fixation dynamics of part by adjusting steel wire pulling force to consolidate Determine part and be allowed to meet various modes to process, the extension range of work, component is simple, and positioning is easy；

3, Fast Installation may be implemented in the fixation device of the utility model, flexible and changeable.
