The utility model discloses a supporting seat that can reciprocate automatically comes the not unidimensional spiral case of adaptation, carries out the bottom sprag to the spiral case to make in the spiral case course of working, avoid taking place the condition of slope skew, improved the processing quality.
Description
Technical Field
The utility model relates to an equipment field of automobile engine booster spiral case riveting and other heavy load riveting location especially pushes up bearing mechanism.
Background
When a volute (workpiece) of the existing engine turbocharger is machined, a bushing needs to be plugged and fixed in a vertical pipe orifice of the volute, and the bottom of the volute is supported by an oil cylinder. In the process of pressing piece installation from top to bottom, the oil cylinder stroke has certain compressibility. The oil cylinder is settled downwards, so that the workpiece is deflected and inclined downwards, and the workpiece is poor or damaged.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the technical problem of description in the background art, the utility model provides a supporting mechanism pushes up comes the not unidimensional spiral case of adaptation through the supporting seat that can reciprocate automatically, carries out the bottom sprag to the spiral case to make in the spiral case course of working, avoid taking place the condition of slope skew, improved the processing quality.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a top load-bearing mechanism, includes base, rotary driving mechanism, an external screw thread section of thick bamboo, movable block and supporting seat, rotary driving mechanism's organism is fixed in the base, and rotary driving mechanism's output shaft end is fixed with an external screw thread section of thick bamboo, has seted up the screw hole in the movable block, and external screw thread section of thick bamboo threaded connection is in the screw hole of movable block, and the supporting seat is installed on the movable block.
Specifically, an arc-shaped groove used for placing the edge of the lateral opening of the volute is formed in the supporting surface of the supporting seat.
Specifically, a guide rod is fixed at the bottom of the supporting seat and penetrates through holes at two ends of the moving block.
In particular, the rotary drive mechanism is a pneumatic motor or an electric motor.
The utility model has the advantages that: the utility model provides a supporting mechanism pushes up comes the not unidimensional spiral case of adaptation through the supporting seat that can reciprocate automatically, carries out the bottom sprag to the spiral case to make in the spiral case course of working, avoid taking place the condition of slope skew, improved the processing quality.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
in the figure, 1 is a base, 2 is a rotary driving mechanism, 3 is an external thread cylinder, 4 is a moving block, 5 is a supporting seat, and 6 is a guide rod.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 is a schematic structural diagram of the present invention.
The utility model provides an upward push up bearing mechanism, includes base 1, rotary driving mechanism 2, an external screw thread section of thick bamboo 3, movable block 4 and supporting seat 5, rotary driving mechanism 2's organism is fixed in base 1, and rotary driving mechanism 2's output shaft end is fixed with an external screw thread section of thick bamboo 3, has seted up the screw hole in the movable block 4, and 3 threaded connection of an external screw thread section of thick bamboo are in the screw hole of movable block 4, and supporting seat 5 installs on movable block 4. An arc-shaped groove (the shape of the positioning surface can be changed according to different workpieces) for placing the side opening edge of the volute is arranged on the supporting surface of the supporting seat 5. And a guide rod 6 is fixed at the bottom of the supporting seat 5, and the guide rod 6 penetrates through the through holes at the two ends of the moving block 4. The rotary driving mechanism 2 is a pneumatic motor or an electric motor.
As shown in fig. 1, the whole load-bearing mechanism is firstly placed below the volute, and the edge of the side opening of the volute is positioned right above the supporting seat 5.
Then, the rotary driving mechanism 2 is started, the output shaft of the rotary driving mechanism 2 drives the external thread cylinder 3 to rotate, and the rotary external thread cylinder 3 drives the movable moving block 4 in threaded connection with the rotary external thread cylinder to move up and down, so that the height of the supporting seat 5 on the movable block 4 is adjusted. Just so can make the laminating of the indent arcwall face of supporting seat 5 and go up the top at the open-ended border bottom of spiral case to the support of going up the top is provided for the bottom of whole spiral case. Therefore, the bush can be pressed and installed in the volute from top to bottom by matching with a device for pressing a workpiece downwards.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
