Description

Quick clamping device for thread machining after heat treatment of thin-wall part

Technical Field

The utility model relates to a processing apparatus of spare part, concretely relates to press from both sides device soon that is used for thread machining behind thin wall part thermal treatment.

Background

In the production and processing, a plurality of parts need to be subjected to quenching and tempering, the finish machining size is processed after the heat treatment, particularly the thin-wall parts with inner taper holes, such as the thread processing of artillery rocket projectile bullet screwdriving parts and the like, the thin-wall parts are easy to deform after the heat treatment, and the taper holes are inconvenient to fix during the thread processing procedure outside the vehicle. At present, a reliable tool meeting the requirements is not available, the size of a part is difficult to guarantee by the existing tool, the efficiency is low, meanwhile, the workpiece is unstable in clamping and is easy to hurt equipment and workers, and great potential safety hazards are brought to production.

Disclosure of Invention

The utility model aims to solve the technical problem that a fast clamp device that is used for thin wall part thermal treatment back screw thread processing is provided, utilize this frock can satisfy the processing of pressing spiral shell part screw thread and technological requirement thereof.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a quick clamping device for thread processing after heat treatment of thin-wall parts is characterized in that a retaining head is arranged at one end of a mandrel, a key groove is formed in the mandrel, a key is embedded in the key groove, a taper sleeve is sleeved on the mandrel, and a gasket and a nut are arranged at the other end of the mandrel.

And a rotation-proof rod is connected to one end of the mandrel with the stop head.

The utility model adopts the above technical scheme design be used for thin wall part thermal treatment back thread machining press from both sides device soon, establishes the dog through the one end at the dabber, sets up the keyway at the dabber, has inlayed the key in the keyway, establishes the taper sleeve at the spindle cover, establishes gasket and nut at the other end of dabber. When the thin-wall part clamping device is used, a plurality of thin-wall parts to be machined can be fixedly arranged on the mandrel in a penetrating mode to be machined, the workpiece clamping speed is high, the operation is easy, the production efficiency is high, the machining error of a product is small, the quality is high, and the use is safe and reliable. The utility model discloses simple structure, low in manufacturing cost.

Detailed Description

The following will specifically describe the quick clamping device for thread processing after heat treatment of thin-walled parts according to the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 9, the quick clamping device for thread processing after heat treatment of thin-walled parts of the present invention is to provide a stop 3 at one end of a mandrel 2, wherein the stop 3 acts as a stop for stopping the thin-walled part 10 to be processed at one end of the mandrel 2. The key groove 8 is formed in the mandrel 2, the key 5 is embedded in the key groove 8, the taper sleeve 4 is sleeved on the mandrel 2, the groove 9 is also formed in the inner ring of the taper sleeve 4 along the axial direction, and after the key 5 is embedded into the key groove 8, a part of the key 5 is also embedded into the groove 9 to prevent the taper sleeve 4 and the processed thin-wall part 10 from rotating. The utility model discloses taper sleeve 4 uses keyway 8 as the location to key 5 on the dabber 2 is as the direction, installs taper sleeve 4 and thin wall part 10 during the use in proper order. The angle of the taper sleeve 4 is consistent with that of the processed thin-wall part, so that the stability of the processing size of the part is facilitated due to surface contact. And a gasket 6 and a nut 7 are arranged at the other end of the mandrel 2, and the gasket 6 and the nut 7 are used for fixing a compression part. The utility model discloses the length design size of dabber 2 can be 15 thin wall parts 10 of clamping at every turn, and of course, the design size of dabber 2 also can be the size of other a plurality of thin wall parts 10 of clamping at every turn.

Referring to fig. 9, the utility model discloses still can fix the processing screw thread on the lathe with top 11 and top 12 with the both ends of dabber 2, this kind of condition, establish the dwang 1 of preventing even at a tip that dabber 2 kept off head 3, during the use, the top 11 straight shank position in three-jaw chuck centre gripping left end, dabber 2 is last to prevent that dwang 1 is located between two claws of three-jaw chuck and hug closely a three-jaw side, when the processing equipment main shaft rotates the cutter atress, dabber 2 can follow the main shaft equidirectional rotation, dabber 2 just can not pass by oneself yet.

When the thin-wall part is used, the key 5 is firstly embedded in the key groove 8 of the mandrel 2, a thin-wall part 10 is firstly clamped on the mandrel 2, and the thin-wall part 10 is contacted with the stop 3. And then placing a taper sleeve 4 on the mandrel 2, placing two thin-wall parts 10 in opposite phases, placing a taper sleeve 4 on the mandrel 2 again, and so on until the mandrel 2 is filled with the thin-wall parts 10 and the taper sleeve 4 to the top end of the mandrel 2, installing a gasket 6 on the top end of the mandrel 2, and screwing a nut 7. Referring to fig. 8, the utility model discloses the left end of available three-jaw chuck clamping mandrel 2, the right-hand member of dabber 2 is tight with top, can process the part.

The utility model discloses can be equipped with two dabbers, treat that a dabber on the back that finishes of parts machining, change another dabber and can process the part, two sets of frock alternate use, more save time.
