Description

Machining driving tool

Technical Field

The utility model relates to a frock field mainly is a machining drive frock.

Background

At present, in the machining of shaft parts, a machining clamping mode is to adopt center holes at two ends of a center positioning part, and because a positioning center does not have a function of driving the part to rotate, the part cannot be driven to normally rotate to complete the surface cutting of the part. The clamping ring tool for driving needs to be clamped at the large end of a shaft part, as shown in fig. 1-2, three bolts 2 are arranged on a clamping ring 1, before clamping is finished, the bottom surfaces of the three bolts form an inner diameter circle, the diameter of the inner diameter circle is larger than the outer diameter of the large end of the part, after the clamping ring is arranged on an outer circle of the large end, the bolts are screwed by a wrench, a part 3 is tightly jacked after the bolts are screwed, the clamping ring is firmly fixed on the part, then the part and the clamping ring are positioned on a tip, and the tail tip jacks the part through hydraulic pressure. When the driving clamping ring rotates, the bolt is driven to drive the part to rotate together, and the part finishes machining and cutting.

The defects of the technology are as follows: before machining chips, each part needs to be manually provided with a clamping ring, a bolt is screwed by a spanner, the bolt still needs to be unscrewed by the spanner after the chips are machined, and the clamping ring is detached from the part. On one hand, the labor intensity is high due to the action of screwing the bolt, and on the other hand, the production efficiency is low due to the fact that each part needs to be assembled and disassembled with the clamping ring.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a machining drive frock.

The purpose of the utility model is achieved by the following technical scheme. The utility model provides a machine tooling drive frock, includes spring support seat and drive chuck axle, and the spring support seat suit is epaxial and be sliding connection at the drive chuck, and it is top to be equipped with in the drive chuck axle, is equipped with the spring between spring support seat and the drive chuck axle, and the one end of spring is connected with the interior terminal surface cooperation of drive chuck axle, and the other end of spring is connected with the interior terminal surface cooperation of spring support seat, and the lateral part of spring support seat is equipped with the fitting surface with the laminating of part inner wall.

Furthermore, the spring supporting seat comprises a base and a barrel, the barrel is sleeved on the driving chuck shaft, a gap with a certain distance is reserved between the end face of the barrel and the inner end face of the driving chuck shaft, the other end of the spring is connected with the inner end face of the base in a matched mode, and a matching surface attached to the inner wall of a part is arranged on the side portion of the base.

Further, the length of the spring is greater than the length of the barrel.

Furthermore, the tip and the tail tip are on the same axis and are respectively used for positioning and supporting the central holes at two ends of the part.

Furthermore, a plurality of teeth which are uniformly distributed along the circumference are arranged on the matching surface.

Further, the teeth are vertical teeth arranged in a radial direction.

The beneficial effects of the utility model are that: frock can the direct mount top, through the tight laminating of pushing away of frock and part inner wall, the drive part is rotatory, does not need the manual clamping ring of installing on the part, cancelled the installation and dismantled the process step, alleviateed intensity of labour, improved production efficiency.

Description of reference numerals: the clamping ring comprises a clamping ring 1, a bolt 2, a part 3, a tip 4, a tail tip 5, a driving chuck shaft 6, a spring 7, a spring supporting seat 8, a matching surface 8-1, teeth 8-2, a base 8-3 and a barrel 8-4.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in fig. 3-4, a machining driving tool comprises a spring support 8 and a driving chuck shaft 6, wherein the spring support 8 comprises a base 8-3 and a cylinder 8-4, the cylinder 8-4 is sleeved on the driving chuck shaft 6 and is in sliding connection, and a gap with a certain distance is reserved between the end surface of the cylinder 8-4 and the inner end surface of the driving chuck shaft 6. The driving chuck shaft 6 is internally provided with a tip 4, a tail tip 5 is correspondingly arranged, and the tip 4 and the tail tip 5 are on the same axis and are respectively used for positioning and supporting center holes at two ends of the part 3. A spring 7 is arranged between the spring supporting seat 8 and the driving chuck shaft 6; one end of the spring 7 is connected with the inner end face of the driving chuck shaft 6 in a matching mode, the other end of the spring 7 is connected with the inner end face of the base 8-3 in a matching mode, the length of the spring 7 is larger than that of the barrel 8-4, and a matching face 8-1 attached to the inner wall of the part 3 is arranged on the side portion of the base 8-3.

As a preferable scheme, a plurality of teeth 8-2 uniformly distributed along the circumference are arranged on the matching surface 8-1, and in this embodiment, the teeth 8-2 are vertical teeth arranged along the radial direction. The purpose of the teeth 8-2 on the mating surface 8-1 is to increase the friction between the mating surface 8-1 and the inner wall of the part 3.

The working principle and the process are as follows: the novel tool is characterized in that a spring supporting seat 8 is arranged on a driving chuck shaft 6, vertical strip-shaped teeth are arranged on the inclined surface of the spring supporting seat 8, a high-strength spring 7 is arranged on the spring supporting seat 8, the novel tool is assembled on a tip 4 at one end, when a part 3 is to be clamped, a center hole of the part 3 is matched with a positioning tip 4, a tail tip 5 is tightly pressed through hydraulic pressure, at the moment, due to the acting force of the tail tip 5, the spring 7 is compressed, one end of the spring 7 tightly presses an inner end surface of the driving chuck shaft 6, the other end of the spring tightly presses a base end surface of the spring supporting seat 8, and a matching surface 8-1 (inclined surface) with teeth of the spring supporting seat 8 is tightly pushed and attached to the inner wall of the part 3. When starting processing, drive chuck axle 6 is rotatory, because spring 7 is compressed the left right direction thrust that produces, drives spring support 8 through spring 7 rotatory, and the tooth on spring support's the fitting surface closely pushes away tight cooperation with the part inner wall, drives the part 3 rotation again, has accomplished part surface smear metal. After the machining is finished, the tail tip 5 is loosened, the blanking is performed directly, the next part is machined, the feeding is performed directly again, and the driving tool does not need to be installed and disassembled.

It should be understood that the technical solutions and the inventive concepts of the present invention as equivalent as those of the skilled in the art should be replaced or changed by the claims.
