Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure vessel manufacturing, in particular to the technical field of circular ring processing in a heat exchanger, and specifically relates to a circular ring machining tool. Background Art
[0002] At present, in the design and manufacture of pressure vessels, some types of heat exchangers are provided with grid baffles, the middle part of the grid baffle is a grid, and the outside is a ring. The outer circle of the ring needs to be machined to ensure that the outer diameter of the ring is compatible with the cylinder of the heat exchanger. The existing machining platform includes a disc, multiple claws, multiple bolts, and multiple nuts. The top surface of the disc is provided with multiple inverted T-shaped grooves arranged radially along its length direction. Multiple bolts are respectively matched with multiple inverted T-shaped grooves. Multiple claws are arranged circumferentially on the disc, and the claws are fixed to the disc by bolts and nuts. When processing the ring, the outer side of the multiple claws is pressed against the inner ring of the disc to achieve the positioning and clamping of the ring. However, when clamping by the claws, the disc is easily deformed or broken and the center of the circle is not accurately positioned, thereby affecting the processing quality of the ring. Summary of the invention
[0003] In order to solve the problems that the disc is easily deformed or broken and the center of the circle is not accurately positioned when the disc is clamped by the clamping claws, the utility model provides a new tooling for machining a circular ring.
[0004] The utility model is realized by adopting the following technical solutions:
[0005] A circular ring machining tool, including a circular disc in a machining platform, a plurality of inverted T-shaped grooves arranged radially along the length direction are opened on the top surface of the circular disc, and also includes a plurality of bolts and nuts, a pressure plate, and a cross support plate. A plurality of strip holes matched with the inverted T-shaped grooves are opened on the pressure plate, the outer diameter of the pressure plate is larger than the inner diameter of the circular ring to be machined, the cross support plate is coaxially fixed to the bottom surface of the pressure plate and the cross support plate is matched with the inner diameter of the circular ring to be machined (it is well known to those skilled in the art that the cross support plate is matched with the inner diameter of the circular ring to be machined refers to the clearance fit between the cross support plate and the inner diameter of the circular ring to be machined, which can not only realize the positioning of the circular ring to a certain extent, but also facilitate the insertion of the cross support plate into the inner ring of the machined circular ring), the thickness of the cross support plate is less than the thickness of the circular ring to be machined.
[0006] When in use, remove the claws on the machining platform, then place the ring to be processed on the machining platform, place the cross support plate together with the pressure plate in the ring to be processed, and make the four end points of the cross support plate support on the inner ring of the ring to be processed, and finally pass the bolts through the corresponding inverted T-slots, the cross support plate, and the strip holes and tighten them on the nuts to achieve a fixed connection between the machining platform and the pressure plate, thereby achieving the positioning and clamping of the ring to be processed on the machining platform.
[0007] The beneficial effects produced by the utility model are as follows: the circular ring machining tooling structure of the utility model is simple and the manufacturing cost is low. The upper and lower clamping of the pressure plate and the machining platform and the internal support of the cross support plate effectively solve the problem of processing deformation of the circular ring. The strip holes matched with the inverted T-shape arranged on the pressure plate and the cooperation with the bolts solve the problem of inaccurate center positioning, thereby effectively improving the processing quality of the circular ring.
