Description

Eccentric processing frock of pressure shell

Technical Field

The utility model relates to a processing frock specifically is a pressure shell eccentric machining frock.

Background

The design and manufacture of the eccentric tool clamp of the numerical control lathe are particularly important for the working efficiency and the precision of machining of various complicated pipe orifices. The pressing shell eccentric part is widely applied to an automobile engine, but the processing technology of the pressing shell eccentric part is complex, and the main problem is that the eccentricity is difficult to adjust. During batch production, if the machining and assembly table is difficult to correct according to the traditional method, the swing of a machine tool is large, a main shaft bearing is easy to wear, the machining efficiency is low, and the requirements on the size and the tolerance are not easy to meet.

Chinese patent with patent number CN201720993926.4 discloses a fixed frock of turbine pressure shell, this utility model includes the upper base, the upper base is provided with closing device and the trepanning that is used for fixed turbine pressure shell, fixed lug is worn to be equipped with by the trepanning, fixed lug's upper end is connected with the cover connection piece, the diameter and the turbine pressure shell phase-match of cover connection piece, the lower extreme of upper base is connected with down the base, lower base is provided with the recess that is "T" shape, recess and trepanning intercommunication, be provided with in the recess with the equal the same T-shaped piece of recess shape form size, the T-shaped piece passes through bolt fixed connection with fixed lug. The utility model discloses a through behind turbine pressure shell and cup joint piece joint, the turbine pressure shell can only carry out the rotation in a circumferential direction along the axial lead of cup joint piece, and then makes the axial lead rigidity of turbine pressure shell to make closing device and turbine pressure shell separation back, can carry out the rotation in a circumferential direction to the turbine pressure shell, thereby play the effect that promotes the machining efficiency to the turbine pressure shell. But this utility model to turbine shell with cup joint the piece joint, make the turbine pressure shell rotatory again, make wearing and tearing great like this, the cost is higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: in order to solve the problem, a pressing shell eccentric machining tool is provided. In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an eccentric processing frock of pressure shell, includes the flange bottom plate, be equipped with the round pin locating plate on the flange bottom plate, be close to the round pin locating plate is equipped with the dynamic balance balancing weight, be equipped with the backup pad on the round pin locating plate, be equipped with the product positioning dish in the backup pad, run through the product positioning dish is equipped with central locating lever, be equipped with the clamp plate on the central locating lever.

Preferably, the product positioning disc is obliquely arranged, and the beneficial effects are that the pressing shell is also obliquely arranged by the arrangement, so that the pressing shell is ensured to deviate from the rotating circle center, and the pressing shell is eccentrically processed.

Preferably, the flange bottom plate is circular, the center of a circle of the flange bottom plate is consistent with the axis of a rotating shaft of a machine tool, the tool has the advantages that the circular structure is designed to facilitate rotation, the whole tool rotates by taking the center of a circle of the flange bottom plate as an axis during shell pressing processing, the processing efficiency is higher through rotating processing, and the automation level is improved.

Preferably, the dynamic balance balancing weight is at least one, and the beneficial effects are that shake appears when preventing whole frock rotation through setting up the dynamic balance balancing weight, make whole frock keep dynamic balance.

Preferably, run through the dynamic balance balancing piece is equipped with the counter weight locating lever, beneficial effect be through it the dynamic balance balancing piece with the flange bottom plate is fixed, prevents that the rotational speed is too fast to lead to the dynamic balance balancing piece to keep away from the motion of rotation axis, and the dynamic balance state is destroyed, and the shake appears in whole frock.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses make the pressure shell product can carry out the rotation processing in this frock to this frock has wholly realized dynamic balance, makes the lathe swing very little, and the main shaft is difficult for wearing and tearing, and improve equipment life has reduced personnel intensity of labour, improves work efficiency, and can batch production, and stable in size, convenient and fast.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: 1. a flange base plate; 2. a round pin positioning plate; 3. a dynamic balancing weight block; 4. a support plate; 5. a counterweight positioning rod; 6. a product positioning plate; 7. pressing a plate; 8. a central positioning rod.

Detailed Description

The first embodiment is as follows:

the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, a pressing shell eccentric processing tool comprises a flange bottom plate 1, wherein a round pin positioning plate 2 is arranged on the flange bottom plate 1, a dynamic balance weight block 3 is arranged close to the round pin positioning plate 2, at least one dynamic balance weight block 3 is arranged, and the dynamic balance weight block 3 is arranged to prevent the whole tool from shaking during rotation, so that the whole tool is kept in dynamic balance; a counterweight positioning rod 5 is arranged to penetrate through the dynamic balance weight block 3, and the dynamic balance weight block 3 and the flange bottom plate 1 are fixed through the counterweight positioning rod, so that the dynamic balance weight block 3 is prevented from moving away from a rotating axis due to an excessively high rotating speed, a dynamic balance state is damaged, and the whole tool shakes; the round pin positioning plate 2 is provided with the supporting plate 4, the supporting plate 4 is provided with the product positioning disc 6, the flange bottom plate 1 is circular, the circle center of the flange bottom plate 1 is consistent with the axis of a rotating shaft of a machine tool, the round structure is designed to facilitate rotation, the whole tool rotates by taking the circle center of the flange bottom plate 1 as the axis when a product is machined, the machining efficiency is higher through rotary machining, and the automation level is improved; the product positioning disc 6 is obliquely arranged, so that the product is also obliquely arranged, the product is ensured to deviate from the center of a rotating circle, and the product is eccentrically processed; a central positioning rod 8 penetrates through the product positioning disc 6, a pressing plate 7 is arranged on the central positioning rod 8, and the pressing plate 7 is used for pressing the product; the utility model discloses make the pressure shell product can carry out the rotation processing in this frock to this frock has wholly realized dynamic balance, makes the lathe swing very little, and the main shaft is difficult for wearing and tearing, and improve equipment life has reduced personnel intensity of labour, improves work efficiency, and can batch production, and stable in size, convenient and fast.
