Description

Soft clamping claw combined jig

Technical Field

The utility model relates to a soft gripper combination tool.

Background

In the machining industry, a numerically controlled lathe is one of the most widely used mechanical devices, and workpieces are clamped and machined by the numerically controlled lathe generally by a three-jaw chuck and a soft jaw. When a conventional thin sheet, an irregular sheet and the like are fixed through a three-jaw chuck, the pressure is too low, the phenomenon of unfirm fixation is easily generated, the eccentricity is serious, and the workpiece is easily scratched when the pressure is too high.

Disclosure of Invention

The utility model relates to a soft jack catch combination tool that forms is improved on soft jack catch of lathe for the location clamping of thin wall work piece, irregularly shaped work piece etc. The use method is simple, the applicability is strong, the positioning is accurate, the processing period is shortened on the basis of guaranteeing the accuracy of the central hole, and the production efficiency is improved.

The purpose of the utility model is realized through the following technical scheme:

the soft clamping jaw combined jig comprises a three-jaw chuck 1, wherein a soft clamping jaw 2 is arranged on the three-jaw chuck 1, and an upper fixed block 3 and a lower fixed block 4 are respectively welded on the upper surface and the rear end surface of the soft clamping jaw 2; the upper fixing block 3 is provided with a hole at the overlapping position of the soft clamping jaw 2. The upper fixing block 3 is provided with an arc step surface which is gradually increased from front to back, and the arc step surface forms a clamping surface for fixing a workpiece; two threaded holes are formed in the lower fixing block 4, the countersunk head screws 6 penetrate through the threaded holes to be connected with the lower fixing block 4, the nuts 7 are locked with the countersunk head screws 6, and the round strong magnets 5 are connected with the countersunk head screws 6.

The utility model has the advantages that: the utility model discloses soft jack catch combination tool, the suitability is strong, and the location is accurate, can ensure on the basis of centre bore precision, shortens processing cycle, improves production efficiency.

Detailed Description

The technical scheme of the utility model is further explained in the following with the attached drawings.

The parts in the drawings are numbered as follows: 1. three-jaw chuck, 2, soft jack catch, 3, upper fixed block, 4, lower fixed block, 5, round strong magnet, 6, countersunk screw, 7, nut

Referring to the attached drawings, the soft clamping jaw combined jig comprises a three-jaw chuck 1, wherein a soft clamping jaw 2 is arranged on the three-jaw chuck 1, and an upper fixed block 3 and a lower fixed block 4 are respectively welded on the upper surface and the front end surface of the soft clamping jaw 2; the upper fixing block 3 is provided with a hole at the overlapping position of the soft clamping jaw 2. The upper fixing block 3 is provided with an arc step surface which is gradually increased from front to back, and the arc step surface forms a clamping surface for fixing a workpiece; two threaded holes are formed in the lower fixing block 4, the countersunk head screw 6 penetrates through a certain threaded hole to be connected with the lower fixing block 4, the nut 7 is locked with the countersunk head screw 6, and the round strong magnet 5 is connected with the countersunk head screw 6.

The lower surface of the upper fixing block 3 is flush with the middle and side-by-side upper surface of the soft clamping jaw 2; the front end face of the lower fixing block 4 is flush with the middle leaning edge of the rear end face of the soft clamping jaw 2.

The upper fixing block 3 is provided with an arc step surface which is gradually increased from front to back to fix the workpiece.

The countersunk head screw 6 passes through one of the two threaded holes to be matched with the fixed block b according to the outer diameter of the workpiece.

The round strong magnet 5 is provided with a counter bore which is matched with the counter head screw 6 to further fix the workpiece and prevent eccentricity.

The embodiments described in this specification are merely illustrative of implementations of the inventive concept and the scope of the invention should not be considered limited to the specific forms set forth in the embodiments but include equivalent technical means as would be recognized by those skilled in the art based on the inventive concept.
