The utility model has the advantages of fixed clamping, simple and rapid operation, convenient hoisting, high efficiency of clamping workpiece, low production cost, and convenient manufacture and maintenance.
Description
Technical field
The utility model relates to a kind of milling machine cutting jig, belongs to the machining appurtenance.
Background technology
At present, in the tube groove working angles, the mode that clamping work pieces generally adopts is that spiral clamps and hydraulic clamp, and spiral clamps, the troublesome poeration effort, and also easily the generation vibration gets loose; Hydraulic clamp can continue to clamp, but, mostly be to press down, also will move for the workpiece of different size and press down the center, when workpiece size changes, need the position of mobile clamping cylinder from the workpiece top, otherwise can not workpiece pressing, larger-size workpiece is because the component affects of press mechanism can't realize lifting, bulky, and clamping workpiece efficient is low.
The utility model content
The purpose of this utility model is to provide a kind of improved milling machine cutting jig, and clamping is firm, and is simple and efficient to handle, and lifting is convenient, clamping workpiece efficient height.
Milling machine cutting jig described in the utility model has the U-shaped geometrical clamp that Open Side Down, and with the corresponding lever jig arm clamping head that is provided with in the under shed outside of U-shaped geometrical clamp, the lever jig arm other end piston rod of the hydraulic jack corresponding with it respectively is hinged.
With Hydraulic Station as power source, box house at lathe is installed hydraulic jack and clamping head, utilize lever jig arm principle to change clamping direction and clamping force is amplified, thereby clamping work pieces can change the last pressure type from the top down of routine into lower-gripping type from bottom to top like this, and structure is compact more, and can conveniently lift workpiece, improve the security of workpiece loading and unloading, shortened the lay day, improved operating efficiency.
The design of lever jig arm clamping head there is the clamping plane, adjusts the clamping situation.
By the distance of adjustment with geometrical clamp, can change the clamping force size, by the hydraulic valve pressure regulation, also can change and step up the power size.
Set up the 3rd lever jig arm clamping head at the rear of any one lever jig arm clamping head, the piston rod of the other end of the 3rd lever jig arm and the 3rd hydraulic jack is hinged.Thereby can be in use, with two in three clamping heads sides that place workpiece, another places the opposite side of workpiece, form the bikini clamping and positioning, solid and reliable, and need not can clamp operation to the workpiece of multiple size in mobile clamping cylinder position, convenient and swift.For long, bigger or erose workpiece, the lever jig arm of varying number can be set in different positions as required also.
The utility model compared with prior art has following beneficial effect:
(1) be applicable to the clamping and positioning of the big workpiece of milling machine, adopt hydraulic clamp, clamping force is big and can regulate within the specific limits, clamps firmly, and is flexible.Can pass through the hand-operated valve control operation, but also electrical appliance control or use the PLC program and realize control automatically.
(2) the last pressure mode with routine changes down the folder mode into, and working space is open, and lifting dismounting workpiece is convenient, safe and reliable, the operating efficiency height.
(3) adopt three oil cylinders to distribute and clamp, make the workpiece positioning stablity.
(4) simple in structure, cost of manufacture is low, making and easy to maintenance.
Description of drawings
Fig. 1 is that the utility model one embodiment is combined in the easy structure schematic diagram under the application state.
Among the figure: 1, workpiece 2, U-shaped geometrical clamp 3, clamping head 4, lever jig arm 5, lever jig arm fulcrum shaft 6, articulated axle 7, piston rod 8, hydraulic jack.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
As shown in Figure 1, milling machine cutting jig described in the utility model, the U-shaped geometrical clamp 2 that Open Side Down is arranged, correspondingly with the under shed of U-shaped geometrical clamp 2 outside be provided with two lever jig arm clamping heads, clamping head 3 with the right side is the example explanation, clamping head 3 has the clamping plane, the piston rod 7 of the hydraulic jack 8 that lever jig arm 4 other ends are corresponding with it is hinged by articulated axle 6, the rear of clamping head 3 is provided with the 3rd lever jig arm clamping head, and the piston rod of the other end of the 3rd lever jig arm and the 3rd hydraulic jack is hinged.
In like manner, the 3rd lever jig arm clamping head being set at the rear of another clamping head also is the same.Concrete condition can be decided according to the shape of workpiece.
During use, by U-shaped geometrical clamp 2 workpiece 1 is placed on the workbench, promote an end of lever jig arm 4 by hydraulic jack 8, the clamping head 3 that makes lever jig arm 4 other ends is under the effect of lever jig arm fulcrum shaft 5, by U-shaped geometrical clamp 2 workpiece 1 is clamped, the arm of force size that changes lever jig arm 4 can change the size of clamping force, and three clamping heads can form three stress points and clamp by 2 pairs of workpiece 1 of U-shaped geometrical clamp.When hydraulic jack 8 rollbacks, clamping is unclamped, and is easy and simple to handle.The bikini clamping mode need not can the workpiece of multiple size be clamped mobile hydraulic jack position, and following folder mode makes things convenient for the lifting of large-scale workpiece.
Claims (3)
1. a milling machine cutting jig is characterized in that the U-shaped geometrical clamp that Open Side Down is arranged, and with the corresponding lever jig arm clamping head that is provided with in the under shed outside of U-shaped geometrical clamp, the lever jig arm other end piston rod of the hydraulic jack corresponding with it respectively is hinged.
2. milling machine cutting jig according to claim 1 is characterized in that lever jig arm clamping head has the clamping plane.
3. milling machine cutting jig according to claim 1 and 2 is characterized in that the rear of a lever jig arm clamping head is provided with the 3rd lever jig arm clamping head, and the piston rod of the other end of the 3rd lever jig arm and the 3rd hydraulic jack is hinged.
