Description

Technical Field

[0001] The invention relates to the technical field of disc spring processing, and in particular to a positioning device for disc spring processing. Background Art

[0002] Disc springs are special springs that are tapered in the axial direction and bear loads. After being deformed under load, they store a certain amount of potential energy. When the bolts become loose, the disc springs release part of the potential energy to maintain the pressure between the flange connections to meet the sealing requirements. The stress distribution of disc springs decreases evenly from the inside to the outside, which can achieve the effect of low stroke and high compensation force. The existing disc springs are not convenient to position during the processing process, so a positioning device that facilitates the positioning of disc springs is needed to solve this defect. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a positioning device for processing butterfly springs, thereby overcoming the deficiencies of the prior art.

[0005] The beneficial effect of the present invention is that when using the positioning device for processing butterfly springs, the unloading ring is removed from the fixed column, the butterfly spring to be processed is installed on the fixed column through the fixing component, and then the fixed column is driven down by the lifting mechanism, and the fixed column drives the unloading ring to descend, so that the butterfly spring can be fixedly installed on the positioning plate, which is easy to operate.

[0006] Further: the fixing assembly includes a fixing block, the diameter of the fixing block is smaller than the diameter of the fixing column, the top of the fixing block is provided with a groove, the groove is provided with a button block, the side wall of the button block is provided with a limit block, the side wall of the groove is provided with a limit groove matching the limit block, two through holes are symmetrically provided at the lower end of the groove side wall, telescopic blocks are provided in the two through holes, a connecting block is provided at the center of the bottom of the groove, the opposite ends of the two telescopic blocks are respectively connected to the connecting block through springs, two triangular protrusions are symmetrically provided at the bottom of the button block, the tops of the opposite ends of the two telescopic blocks are provided with triangular grooves matching the triangular protrusions, the unloading ring is sleeved on the fixed block, and the bottom and top of the unloading ring are respectively abutted against the fixed column and the two telescopic blocks.

[0007] The beneficial effect of the above further scheme is: when it is necessary to remove the unloading ring from the fixed column, press the button block, the button block drives the two triangular protrusions to descend, and the two triangular protrusions drive the two telescopic blocks to move through the triangular grooves provided on the telescopic blocks, so that the two telescopic blocks are respectively retracted into the two through holes, and the unloading ring can be passed through the two telescopic blocks to be removed from the fixed column; when it is necessary to install the unloading ring on the fixed column, press the button block, so that the two telescopic blocks are respectively retracted into the two through holes, and the unloading ring can be passed through the two telescopic blocks to be fixed on the fixed column.

[0008] Further: the tops of the opposite ends of the two telescopic blocks are both provided with inclined surfaces.

[0009] The beneficial effect of the above further solution is that the inclined surface can facilitate the unloading ring to pass through the two telescopic blocks and be fixed on the fixed column.

[0010] Further: the lifting mechanism includes a threaded sleeve, a guide assembly, a threaded rod and a motor, the upper end of the threaded sleeve is connected to the lower end of the fixed column, the outer wall of the threaded sleeve is connected to the bottom of the positioning plate through the guide assembly, the threaded rod is arranged in the threaded sleeve, the lower end of the threaded rod is connected to the output shaft of the motor, and the motor is installed on the top of the base plate.

[0011] The beneficial effect of the above further solution is that the motor can drive the threaded rod to rotate, while the guide assembly can only allow the threaded sleeve to rise and fall, the threaded rod can drive the threaded sleeve to rise and fall, and the threaded sleeve can drive the fixed column to rise and fall.

[0012] Further: the guide assembly includes two guide sleeves and two guide rods, the two guide sleeves are symmetrically arranged on the side wall of the threaded sleeve, the two guide rods are respectively arranged in the two guide sleeves, and the upper ends of the two guide rods are respectively connected to the bottom of the positioning plate.
