Abstract
The invention discloses a clamp for milling flat tenons in batch. The clamp includes a clamp body; a plug and a clamping block are arranged on two ends of the clamp body respectively; a clamping screw and an adjustment screw are arranged on the clamping block; a groove is formed in the central line of the clamp body; a special-shaped positioning block is each arranged on two ends of the groove, and at least one position block is arranged in the center of the groove; at least one positioning hole for positioning a cover plate is formed in two sides of the grooves of the clamp body; the cover plate is positioned through cylindrical pins matching the positioning holes, and is tightly fixed on the clamp body through at least one sunk screw. An arc surface clamping manner replaces a three-point clamping manner of a V-shaped block, deformation and damage to a surface can be avoided, the quality of products can be ensured, and the rejection rate is greatly decreased; and the clamp can process parts in batch, can remarkably improve the production efficiency, and can reduce the working intensity and the production cost.
Description
Technical field
The invention belongs to field of machining, more particularly to a kind of fixture for the flat tenon of batch milling.
Background technology
On milling machine during the flat tenon of milling, most of fixture adopts vee-block clamping device, but to such as figure
The part of shape shown in 1, clamps according to vee-block, then can bring difficulty to Milling Process.By Fig. 1
Know, when clamping milled part two sides with vee-block, if being clamped with 10 excircle orientations of φ, due to its length
Too short, only 5mm is spent, though can clamp, away from clamping dot center, insufficient clamping force, milling
When workpiece easily beaten by milling cutter and fly, and high clamping force, and easily its clamping surface is crushed or three are pressed from both sides into
It is angular and scrap.If sandwiched in vee-block with 18 Excircle machining surfaces of φ processing, workpiece end face then cannot
Positioning, easily causes mismachining tolerance.
If processing is clamped using chuck is single, not only occur situation about being similar to using vee-block, i.e.,
The feasible quality stability that cannot also improve efficiency and ensure product reluctantly is made, batch milling is not suitable for.
The content of the invention
It is an object of the invention to overcome the problem above that prior art is present, there is provided a kind of for batch
The fixture of the flat tenon of milling, can either meet Workpiece clamping, the requirement of positioning, can realize batch milling again
Cut.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is by the following technical programs
Realize：
A kind of fixture for the flat tenon of batch milling, including chuck body, the two ends of the chuck body
Plug and gripping block are equiped with respectively, and pinching screw and adjusting screw, institute are equiped with the gripping block
State chuck body and be provided with groove positioned at centerline, be located in the groove at two ends be respectively provided with one it is special
Shape locating piece, is provided with least one locating piece positioned at middle, and the chuck body is located at groove both sides
Place is provided with least one location hole for positioning cover plate, and the cover plate is by using cooperatively with location hole
Cylinder finger setting, and be fastened in chuck body by least one sunk screw.
Further, the centre bore between the locating piece is cylindrical with the φ 18 of part is preferably 18H/j56 mistakes
Cross cooperation.
The invention has the beneficial effects as follows：
1st, the 3 points of clamping modes that instead of vee-block are clamped with arc surface, it is to avoid surface crushes and deformation,
Product quality is ensure that, percent defective is greatly reduced.
2nd, batch machining can be carried out to part, significantly improves production efficiency, greatly reduce work strong
Degree, reduces production cost.

Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figures 2 and 3, a kind of fixture for the flat tenon of batch milling, including chuck body 1,
The two ends of the chuck body 1 are equiped with plug 2 and gripping block 3 respectively, install in the gripping block 3
There are pinching screw 31 and adjusting screw 32, the chuck body 1 is provided with groove 11 positioned at centerline,
It is located in the groove 11 at two ends and is respectively provided with a special-shaped locating piece 4, is provided with least positioned at middle
One locating piece 5, the chuck body 1 are located at 11 both sides of groove and are provided with for positioning cover plate 6
At least one location hole 12, the cover plate 6 are fixed by the straight pin 61 used cooperatively with location hole 12
Position, as shown in Figure 4 and Figure 5, and is fastened in chuck body 1 by least one sunk screw 62.
Further, the centre bore between above-mentioned locating piece 5 is cylindrical with the φ 18 of part is preferably 18H/j56
Interference fits.
The operation principle of the present embodiment is as follows：
Plug 2 in chuck body 1 plays the role of positioning, according to the quantity with milled part by well cutting
Special-shaped locating piece 4, locating piece 5 is sequentially placed in the groove 11 of chuck body 1, then by cylinder
Pin 61 is had good positioning cover plate 6, and gripping block 3 is adjusted to appropriate location by adjusting screw 32, using heavy
Head screw 62 has fastened cover plate 6；One group of part with milling is positioned at into 5 centre bores of each locating piece
It is interior, as each locating piece 5 is can move freely in groove 11, pinching screw 31 is tightened after positioning, is made
Each locating piece 5 and part are produced and are mutually extruded, so as to the purpose for realizing clamping.The present invention is ensureing to add
In the case of work positional precision, the milling compared with large inflow can be carried out.
