Description
Technical Field
The utility model relates to a, specifically speaking.
Background
The thin-wall part is easy to vibrate during machining, the vibration affects the machining precision, the product productivity and the part quality, and particularly, the workpiece is difficult to clamp and support and the small cutting force can generate large vibration. Therefore, it is very important to add auxiliary support in the processing of thin-wall parts. The existing thin-wall part supporting tool cannot control the supporting force and adjust the proper supporting force, so that the application range is not wide, and the product quality is influenced.
Disclosure of Invention
An object of the utility model is to provide a solve the light wall spare tremble in the processing and warp the unsteady support of adjustable pressure of scheduling problem.
The purpose of the utility model is realized like this:
the utility model relates to a pressure adjustable floating support, characterized by: the automatic positioning device comprises a base, a positioning cylinder, a telescopic rod and a supporting head, wherein the base comprises a plate and a seat, the seat is fixed on the plate and is of a hollow structure, the hollow structure is used for installing the positioning cylinder through threads, a nut is installed at the upper end of the positioning cylinder, the telescopic rod is arranged in the positioning cylinder, the lower end of the positioning cylinder is connected with an adjusting bolt through threads, a locking nut is connected with the adjusting bolt through threads, a spring is arranged between the telescopic rod and the adjusting bolt, a pressure sensor is connected above the telescopic rod, and the supporting head is connected above the pressure sensor.
The utility model discloses can also include:
1. the lateral wall of seat stretches into the locking jackscrew, and the locking jackscrew passes through the screw thread through the lateral wall with the seat and cooperatees, and the tip of locking jackscrew cooperatees with the telescopic link and realizes the locking of telescopic link.
2. The telescopic rod is in clearance fit with the positioning cylinder.
The utility model has the advantages that:
1. the utility model discloses compare with traditional auxiliary stay, the holding power size can be adjusted according to the processing needs. When a thin-wall plane and a thin-wall inclined plane are turned and milled, the supporting force is adjusted to be below 0.02N, so that the force of the floating support contacting the part is small, the part cannot be deformed, and the part is prevented from shaking.
2. The utility model discloses can be used for the part that the machined surface is thin (below 3mm of wall thickness) very much, the part machining face can lead to the part elastic deformation to appear along with cutter feeding force, and the machined surface kick-backs after the processing, can't reach the dimensional requirement of processing, can adjust the holding power to below 0.001N, makes the floating support contact work piece surface, can not arouse elastic deformation again, reduces the elastic deformation that cutter feeding force brought.
3. The utility model discloses can be used for the part that has warp, the thin wall part is because cutting force or stress release influence produce the deformation, through exerting great power to the part of deformation, less power is applyed to the position of non-deformation, with the part leveling.

Detailed Description
The invention will be described in more detail below by way of example with reference to the accompanying drawings:
referring to fig. 1-3, the utility model comprises a base 1, a plate 1-1, a seat 1-2, an adjusting bolt 2, a locking nut 3, a positioning cylinder 4, a spring 5, a telescopic rod 6, a nut 7, a pressure sensor 8, a supporting head 9, a pressure sensor display 10 and a locking jackscrew 11.
The base 1 is formed by welding a plate 1-1 and a seat 1-2, and the base 1 is connected with a T-shaped groove of a machine tool through a T-shaped groove bolt or is tightly pressed on a tool through a bolt. The positioning cylinder 4 is connected with the base 1 through threads, the height of the floating support can be adjusted by rotating the positioning cylinder 4, and the positioning cylinder 4 is locked through a nut 7. Adjusting bolt 2 and location section of thick bamboo 4 are with threaded connection, and telescopic link 6 and 4 clearance fit of a location section of thick bamboo, telescopic link 6 slidable. The telescopic rod 6 is connected with the pressure sensor 8 through threads, and the pressure sensor 8 is connected with the support head 9 through threads. The locking nut 3 is connected with the adjusting bolt 2 by screw thread. The pressure sensor display 10 is connected to the pressure sensor 8 by a socket. The locking jackscrew 11 is connected with the base 1 through screw threads (the locking jackscrew cannot be jacked after being rotated). When in use, the spring 5 is positioned between the adjusting bolt 2 and the telescopic rod 6 and is in a compressed state. By rotating the adjusting bolt 2, the compression pressure of the spring 5 increases (decreases), and the supporting force transmitted to the supporting head 9 increases (decreases).
Before the part is clamped, a plurality of floating supports (the number of the floating supports is selected according to the actual processing condition) are placed on the machine tool surface, and the floating supports are tightly pressed on the machine tool surface through T-shaped groove bolts. The part to be processed is clamped on a machine tool, the positioning cylinder 4 is rotated, the supporting head 9 is adjusted to a proper height through the extension (shortening) of the threaded positioning cylinder 4 of the base 1, and the nut 7 is locked after the adjustment is finished. The pressure sensor display is connected to the pressure sensor 8 through wiring, and the adjusting bolt 2 is rotated according to the reading of the pressure sensor to adjust the proper supporting force. After adjustment is finished, the adjusting bolt 2 is locked by rotating the locking nut 3, and the adjusting bolt 2 is prevented from loosening and falling. And rotating the locking jackscrew 11 to lock the telescopic rod 6 and keep the supporting force of the supporting head 9 on the part.
And (4) pulling out the plug of the pressure sensor display 10, connecting the plug to other floating supports, and adjusting the pressure values of the other floating supports.
After all the floating supports are adjusted, the pressure sensor display plug can be pulled out for processing.
