Abstract
一种轴类多件夹紧胎具，连接板和压紧板之间通过支撑柱相连接，在固定座上设有固定架，在固定架和连接板上均开有螺纹孔，阶梯旋转轴插入固定架和连接板的螺纹孔内，在调整固定套内设有螺纹，阶梯旋转轴的下部延伸至调整固定套内，与调整固定套螺纹连接，阶梯旋转轴带动调整固定套下压，限位连接板套接在阶梯旋转轴上并与连接板相连。本发明可大幅度提高加工精度，产能高，可有效降低成本，方便工人装卸，减少劳动强度，胎具设计轻便。通过两侧的支撑柱把阶梯旋转轴旋转下压的压力一分为二，通过调整固定套将下压的压力一分为三，可完全避免三点压力不均匀。
A shaft-type multi-piece clamping mold, the connecting plate and the pressing plate are connected by a support column, a fixing frame is arranged on the fixing seat, threaded holes are opened on the fixing frame and the connecting plate, and the stepped rotating shaft is provided. It is inserted into the threaded holes of the fixing frame and the connecting plate, and there is a thread in the adjusting and fixing sleeve. The bit connecting plate is sleeved on the step rotating shaft and connected with the connecting plate. The invention can greatly improve the processing precision, has high productivity, can effectively reduce the cost, is convenient for workers to load and unload, reduces labor intensity, and has a light tire design. The pressure of the stepped rotating shaft is divided into two by the support columns on both sides, and the pressure of the downward pressure is divided into three by adjusting the fixed sleeve, which can completely avoid the uneven pressure at the three points.
Description
Technical Field
The invention relates to the field of machining, in particular to a clamping mould.
Background
At present, in order to clamp a plurality of shaft workpieces, a double-layer clamping plate is generally used, and clamping is realized by matching eight bolts. The disadvantages of this design are: the working efficiency is low, and the clamping pressure is uneven, so that the precision requirement of the processed shaft parts cannot be met.
Disclosure of Invention
The invention aims to provide a clamping mould for multiple shafts, which is suitable for grinding single and double flat products of cylindrical surfaces of the shafts, has uniform pressing pressure, can greatly improve the processing precision, has high productivity, can reduce the labor intensity and effectively reduce the cost.
The invention mainly comprises a support column, a pressure plate, a connecting plate, a fixed seat, a fixed mount, a stepped rotating shaft, an adjusting fixed sleeve, a limiting fixed groove and a limiting connecting plate.
Wherein, be connected through the support column between connecting plate and the pressure strip, be equipped with the mount on the fixing base, all open threaded hole on mount and connecting plate, the ladder rotation axis inserts the threaded hole of mount and connecting plate, is equipped with the screw thread in the fixed cover of adjustment, and in the lower part of ladder rotation axis extended to the fixed cover of adjustment, with the fixed cover threaded connection of adjustment, the ladder rotation axis drove the fixed cover of adjustment and pushes down. The limiting connecting plate is sleeved on the stepped rotating shaft and connected with the connecting plate.
Preferably, the fixing base is L-shaped in cross section, a groove is formed in the fixing base, and the processing shaft is placed in the groove in use.
Preferably, the middle part of the support column is provided with an axial through hole, the pressure plate is provided with a threaded hole, and the connecting plate, the axial through hole in the middle part of the support column and the threaded hole in the pressure plate are fixed through bolts.
Preferably, the outer surface of ladder rotation axis upper portion and lower part all is equipped with the screw thread, and ladder rotation axis middle part is opened there is spacing fixed slot, joint spacing connecting plate in spacing fixed slot.
When the invention is used, the fixing frame is arranged on the fixing seat, and the connecting plate and the supporting column are connected with the pressing plate. The ladder rotation axis passes through the screw hole on the mount and rotates to the position of suitable installation on, adjusts fixed cover of adjustment to suitable position, compresses tightly the pressure strip. And inserting the slot on the limiting connecting plate into the groove of the stepped rotating shaft and fixing the slot by using a bolt.
Compared with the prior art, the invention has the following advantages:
(1) the processing precision can be greatly improved, the productivity is high, the cost can be effectively reduced, the assembly and disassembly of workers are facilitated, the labor intensity is reduced, and the mould is light in design.
(2) The pressure for rotating and pressing down the stepped rotating shaft is divided into two by the supporting columns on the two sides, and the pressure for pressing down is divided into three by adjusting the fixing sleeve, so that the uneven pressure of the three points can be completely avoided.

FIG. 3 is a state diagram of the present invention in use;
in the figure, 1-supporting column, 2-pressing plate, 3-connecting plate, 4-fixing seat, 5-fixing frame, 6-step rotating shaft, 7-adjusting fixing sleeve, 8-limiting fixing groove and 9-limiting connecting plate.
Detailed Description
In the schematic diagrams of the present invention shown in fig. 1 to 3, an axial through hole is provided in the middle of the support column 1, a threaded hole is provided in the pressure plate 2, and the connecting plate 3, the axial through hole in the middle of the support column and the threaded hole in the pressure plate are fixed by bolts. The cross-section of fixing base 4 is the L type, is fluted on the fixing base, and the processing axle is placed in the recess during use. Be equipped with mount 5 on the fixing base, all open threaded hole on mount and connecting plate, the surface of 6 upper portions of ladder rotation axis and lower part all is equipped with the screw thread, and the ladder rotation axis inserts the threaded hole of mount and connecting plate. The adjusting fixing sleeve 7 is internally provided with threads, the lower part of the stepped rotating shaft extends into the adjusting fixing sleeve and is in threaded connection with the adjusting fixing sleeve, and the stepped rotating shaft drives the adjusting fixing sleeve to press down. A limit fixing groove 8 is formed in the middle of the stepped rotating shaft, a limit connecting plate 9 is connected in the limit fixing groove in a clamping mode, and the limit connecting plate is connected with the connecting plate.
