Description

Tubular part machining clamp

Technical Field

The utility model relates to the field of machinary, specifically be tubulose spare part adds clamping apparatus.

Background

When machining a machine part, it is necessary to perform positioning and clamping by using various jigs, thereby assisting machine tool machining. When some tubular or annular parts are required to be processed on the outer wall of the tubular or annular parts, the orientation of the outer wall of the parts needs to be changed for a plurality of times, so that the processing operation of a machine tool is facilitated. The current pipe anchor clamps are mostly centre gripping at the pipe outer wall, and fixed pipe is not good through fixed inner wall fixed pipe through centre gripping outer wall, because the centre gripping inner wall enables the outer wall to expose completely, more convenient processing.

Disclosure of Invention

In order to overcome the defects, the utility model provides a tubular part machining clamp.

The technical scheme who adopts in this practicality is as follows:

the utility model discloses a workstation, the bottom fixed mounting of workstation has driving motor, driving motor's output pivot runs through the workstation and extends to workstation upper portion, driving motor's output pivot rotates with the workstation to be connected, driving motor's output pivot fixed connection screw rod, the outer wall threaded connection of screw rod has the swivel nut, the outer wall fixed mounting of swivel nut has a plurality of fixed plates, a plurality of notches have been seted up at the top of workstation, the fixed plate corresponds with the position of notch, the inside sliding connection of notch has support piece, one side of support piece rotates to be connected in the one end of connecting piece, a plurality of the other end of connecting piece all is connected with the rotation of fixed plate.

The number of the fixing plates is equal to that of the notches, and the fixing plates and the corresponding notches are in the same straight line direction.

The number of the fixing plates is four, and the four fixing plates are symmetrically distributed at intervals by taking the threaded sleeve as an axis.

The support piece comprises a vertical plate and two limiting blocks, one end of the vertical plate penetrates through the notch and extends outwards, the two limiting blocks are fixedly sleeved on the outer wall of the vertical plate, the two limiting blocks are respectively arranged on the upper side and the lower side of the notch, the upper limiting blocks and the lower limiting blocks are respectively abutted against the upper surface and the lower surface of the workbench, one end of the connecting piece is rotationally connected with the fixing plate, and the other end of the connecting piece is rotationally connected with the side wall of the vertical plate.

The top fixed mounting of riser has the top support, one side that the top support kept away from the screw rod is the slope setting.

The number of the connecting pieces is a plurality of, and the connecting pieces are arranged in parallel.

The beneficial effects are that: the utility model fixes the tubular component by clamping the inner wall, thus the outer wall is completely exposed, and the processing is more convenient.

FIG. 1 is a perspective view of the present utility;

fig. 2 is a perspective view of a connection structure between a driving motor and a workbench.

In the figure: 1. a work table; 2. a driving motor; 3. a screw; 4. a screw sleeve; 5. a fixing plate; 6. a notch; 7. a support; 8. a connecting piece; 71. a riser; 72. a limiting block; 73. and (5) supporting.

Detailed Description

As shown in fig. 1-2, the automatic feeding device comprises a workbench, wherein a driving motor 2 is fixedly arranged at the bottom of the workbench 1, an output rotating shaft of the driving motor 2 penetrates through the workbench 1 and extends to the upper part of the workbench 1, the output rotating shaft of the driving motor 2 is rotationally connected with the workbench 1, an output rotating shaft of the driving motor 2 is fixedly connected with a screw rod 3, the outer wall of the screw rod 3 is in threaded connection with a screw sleeve 4, a plurality of fixing plates 5 are fixedly arranged on the outer wall of the screw sleeve 4, a plurality of notches 6 are formed in the top of the workbench 1, the fixing plates 5 correspond to the positions of the notches 6, a supporting piece 7 is slidingly connected in the notch 6, one side of the supporting piece 7 is rotationally connected with one end of a connecting piece 8, and the other ends of the connecting pieces 8 are rotationally connected with the fixing plates 5.

The driving motor 2 is started to drive the screw rod 3 to rotate, the support piece 7 connected with the outside of the screw sleeve 4 through the connecting piece 8 slides in the notch 6, so that the screw rod 3 can be rotated under the action of rotary pushing force to enable the screw sleeve 4 to move up and down, meanwhile, the two ends of the connecting piece 8 are respectively hinged with the fixed plate 5 and the support piece 7, and the screw sleeve 4 can drive the four support pieces 7 to synchronously and linearly move in the corresponding notch 6 respectively when in linear movement, so that the distance between the four top supports 73 is increased or reduced, the tubular or annular part is sleeved on the outer walls of the four vertical plates 71, the inner wall of the part is abutted against the surfaces of the top supports 73, and therefore, the screw sleeve 4 can be adjusted according to the diameters of different tubular or annular parts, and is suitable for processing and clamping the tubular or annular parts with different diameters. The utility model fixes the tubular component by clamping the inner wall, thus the outer wall is completely exposed, and the processing is more convenient.
