Abstract

A double-pole milling clamping-piece groove jig is characterized in that the jig consists of two parts of a jig body A and a moving part B, wherein, the jig body A is an integral frame structure that is composed of a ledger plate 8, a floating plate 2, two to five support parts 3, an intermediate locating piece 6, an upper locating piece 7 and a lower locating piece 5, wherein, the intermediate locating piece 6 is inserted in the U-shaped groove of the support part 3 and tightened by bolts, the ledger plate is fixed on the support part 3 by bolts, a spring 1 is fixed between the ledger plate 8 and the floating plate 2 by bolts, the upper locating piece 7 and the lower locating piece 5 are connected with the support part 3 by bolts; the moving part B consists of a connecting rod 12 and an impacted block 11, wherein, a clamping-piece 10 is arranged in the impacted block 11, which pre-tightens the clamping-piece tightly by a bolt 9, the whole moving part B is inserted in the jig body and is tightened on the jig body by a U-shaped impacted block 4. The jig greatly improves the work efficiency of the milling clamping-piece groove and machining accuracy.

Description

Double-pole mills the clip groove anchor clamps

One, technical field:

The utility model relates to a kind of clamping tool for machine work, particularly mills the anchor clamps of intermediate plate elastic groove.

Two, background technology:

Intermediate plate is the vitals in the OVM ground tackle, the wide elastic groove of one 1.5mm (referring to Fig. 4) is arranged above, at present, adopt as shown in Figure 5 the stationary fixture of being made up of clamp body 13, pin 14, cover plate 15 to be installed on the milling machine processes always, its shortcoming is: 1) a complete set of anchor clamps are installed on the milling machine, dress need stop when getting intermediate plate, just can carry out after upper cover plate is taken off, and production efficiency is too low.2) for making the intermediate plate upper end be adjacent to upper cover plate, need firmly to knock upper cover plate left pin is entered in the opening of upper cover plate, also will the blocks of upwards sled of intermediate plate be made it to be adjacent to upper cover plate, beat to the right again when unclamping with instrument, cause anchor clamps loosening easily, influence machining accuracy.

Three, technology contents:

Technical problem to be solved in the utility model is: solve existing stationary fixture and install, use inconvenience, the inefficient problem of anchor clamps processing, a kind of production efficiency of milling the intermediate plate elastic groove and anchor clamps that mill the intermediate plate elastic groove of machining accuracy of improving are provided.

Its solution is: for easy to setup anchor clamps are divided into body and mobile's two parts, mobile utilizes compact heap and coupling bar clamping sheet, and body utilizes latch plate, location-plate is located up and down.

Its concrete structure is: a kind of double-pole mills the clip groove anchor clamps, these anchor clamps are made up of chuck body A and movable part B two large divisions, chuck body A is by fixed head, float plate, 2～5 supporting members, interfix part and last keeper, following keeper is formed a general frame structure, the interfix part inserts the U-lag in the supporting member, and tighten by bolt, fixed head is fixed by bolts on the supporting member, spring with on the bolt between fixed head and float plate, on, following keeper uses Bolt Connection on supporting member, movable part B is by coupling bar, compact heap constitutes, intermediate plate is packed in the compact heap, by bolt intermediate plate is compressed in advance, movable part B is whole to be inserted in the chuck body, by the U-shaped compact heap it is pressed on the chuck body.

Compare with existing stationary fixture, the utility model has following advantage: 1, increase work efficiency greatly: because the utility model anchor clamps are divided into chuck body and movable part two parts, the intermediate plate clamping is in movable part, movable part is fixed on the chuck body and can takes out, one pair of anchor clamps is joined four movable parts, chuck body can be fixed two movable parts simultaneously, in groove milling processing, can adorn the intermediate plate of getting in other two movable parts like this, the dress of workpiece to be machined one intermediate plate picked and placeed outside lathe carry out, thereby improved operating efficiency; 2, improved machining accuracy: milling clip groove will be benchmark with the intermediate plate large end face, and these anchor clamps will be located benchmark and are placed on the chuck body, acts on the power that the intermediate plate small end face makes progress by latch plate the intermediate plate top is attached on the benchmark of location, thereby improved machining accuracy.

The specific embodiment:

A kind of double-pole mills the clip groove anchor clamps, form by chuck body A and movable part B two large divisions, (referring to Fig. 1), chuck body A is by fixed head 8,

float plate

2,3 supporting members 3, interfix part 6 and last keeper 7, following keeper 5 is formed a general frame structure, the U-lag that interfix part 6 inserts in the supporting member 3, and tighten by bolt, fixed head is fixed by bolts on the supporting member 3, on the spring 1 usefulness bolt between fixed head 8 and float plate 2, on, following

keeper

7,5 usefulness Bolt Connection are on supporting member 3, (referring to Fig. 2), movable part B is by coupling bar 12, compact heap 11 constitutes, and intermediate plate 10 is packed in the compact heap 11, intermediate plate is compressed in advance (referring to Fig. 3) by bolt 9, movable part B is whole to be inserted in the chuck body, by U-shaped compact heap 4 it is pressed on the chuck body.

As a kind of conversion of the utility model embodiment, the number of described supporting member 3 can be 2～5.
