Description

Chamfering machine clamp stable in operation

Technical Field

The utility model belongs to the technical field of pipe machining, and relates to a chamfering machine clamp, in particular to a chamfering machine clamp with stable work.

Background

When the steel pipe is processed, in order to facilitate the welding between the later-stage steel pipes, chamfering and flat head processing work of welding grooves are usually carried out on two ends of the steel pipe by using a chamfering machine according to requirements.

When the steel pipe is chamfered, the steel pipe needs to be fixed on a chamfering machine clamp, the structure of the existing chamfering machine clamp is single, the working stability is poor, and the concrete performance is that: the location of synchronizing shaft is comparatively simple, makes its work unstable, leads to stretching out inconsistent with its last gear engagement's left and right sides slider to lead to anchor clamps and host computer blade disc to be eccentric, make the working position of steel pipe eccentric, lead to the product once qualification rate low then, influence whole production line rhythm.

the utility model provides a chamfer machine anchor clamps of job stabilization, includes base, synchronizing shaft, gear, rack, pneumatic cylinder and slider, installs the synchronizing shaft of vertical setting on the base, installs the gear on the synchronizing shaft, has by pneumatic cylinder driven rack in the both sides meshing of gear, and the rack is fixed dress respectively on the slider of both sides, its characterized in that: the pressing device is characterized by further comprising a pressing frame, wherein the pressing frame comprises supporting blocks and pressing plates, the supporting blocks are symmetrically welded on the bases on two sides of the synchronizing shaft, the pressing plates are pressed on the supporting blocks through screws, and an upper shaft hole sleeved with the synchronizing shaft is formed in the middle of each pressing plate.

And the two sides of the pressing plate are provided with spring cylindrical pins which are pinned into the supporting blocks. The synchronous shaft consists of a shaft body and a mounting ring which is arranged on the shaft body, mounting holes are uniformly distributed on the mounting ring at intervals, and a gear is rotatably arranged on the upper part of the shaft body through a copper sleeve;

the base on be equipped with the lower shaft hole that supplies the synchronizing shaft to stretch into, the outer lane in the lower shaft hole of base up end is equipped with the mount table, is equipped with the internal thread in the built-in of the corresponding lower shaft hole on the mount table, the mount ring arrange in the mount table and connect through the hexagon socket head cap screw.

The utility model has the advantages and beneficial effects that:

1. this chamfer machine anchor clamps of job stabilization through add the pressure equipment frame in current synchronizing shaft outside, has guaranteed the stability of gear at the during operation synchronizing shaft, avoids its problem of the left and right sides slider asynchronism that brings because of synchronizing shaft installation is unstable, guarantees the concentricity to the work piece centre gripping.

2. This chamfer machine anchor clamps of job stabilization, through the setting of spring cylindric lock, avoided the problem that the pressure equipment was inefficacy because of the screw looseness brings.

3. This chamfer machine anchor clamps of job stabilization through setting up the synchronizing shaft into the structure that the lower part set up the collar, makes its lower part pass through the screw location, and upper portion passes through the location of last shaft hole, fully guarantees its stability at the gear during operation, guarantees processingquality.

4. The chamfering machine clamp has the advantages of being scientific and reasonable in structural design, stable in work, capable of improving the one-time qualification rate of products, free of influencing the processing progress and easy to realize, and is high in innovation.

Detailed Description

The utility model is further illustrated by the following examples, which are intended to be illustrative only and not limiting in any way.

The utility model provides a chamfer machine anchor clamps of job stabilization, includes base 7, synchronizing shaft 5, gear 3, rack 14, motor and slider 12, installs the synchronizing shaft of vertical setting on the base, installs the gear on the synchronizing shaft, has by pneumatic cylinder driven rack in the both sides meshing of gear, and the rack is fixed respectively on the slider of both sides, and its innovation lies in: the press-mounting device is characterized by further comprising a press-mounting frame 13, wherein the press-mounting frame comprises a supporting block 1 and a pressing plate 2, the supporting blocks are symmetrically welded on bases on two sides of the synchronizing shaft, the pressing plate is pressed on the supporting blocks through screws, and an upper shaft hole sleeved with the synchronizing shaft is formed in the middle of the pressing plate.

Through the setting of pressure equipment frame, can carry out stable location installation to the synchronizing shaft, at gear and rack meshing during operation, can guarantee the synchronism of both sides slider to guarantee the concentricity to the steel pipe centre gripping.

The pressure plate is pressed on the copper sleeve, and in order to avoid the problem of pressure plate press-mounting failure caused by screw loosening, spring cylindrical pins 11 which are pinned into the supporting blocks are arranged on two sides of the pressure plate.

In order to further ensure the stability of the installation of the synchronizing shaft, besides limiting the upper part of the synchronizing shaft through the press-mounting frame, the lower part of the synchronizing shaft is also limited, specifically: the synchronous shaft consists of a shaft body 8 and a mounting ring 10 which is arranged on the shaft body, mounting holes 9 are uniformly distributed on the mounting ring at intervals, and a gear is rotatably arranged on the upper part of the shaft body through a copper sleeve 4;
