Description

Technical Field

[0001] The utility model relates to the technical field of tooling equipment, in particular to a position-limiting lathe tooling. Background Art

[0002] Flange is a circular connector commonly used to connect pipes, containers or equipment, usually made of metal. In the manufacturing process of flange, in order to ensure its connection performance and sealing performance, the end face of the flange needs to be polished. The traditional method of flange end face polishing mainly relies on manual operation, which has problems such as low efficiency, unstable operation and poor consistency.

[0003] The Chinese utility model patent with announcement number CN216859268U discloses a flange end face grinding device, including a chassis, a rotating drive structure, a flange fixing plate structure, and a grinding structure. A fixed plate body is fixedly provided at the upper end of a rotating column, and a plurality of claws for fixing the flange are provided on the fixed plate body. By rotating the adjusting plate, the plurality of claws can be driven to move simultaneously so that the inner ring of the flange is clamped on the fixed plate body, which is conducive to fixing flanges of different diameters.

[0004] However, regardless of the above-mentioned device or the common tooling structure on the market, the flange is mostly fixed by clamping its outer wall, which makes the flange easy to rotate during the grinding process, resulting in reduced grinding effect and efficiency. At the same time, the protruding tooling structure is also easy to cause collision and wear on the grinding tool, reducing the service life of the tool and increasing the production cost of the enterprise. Utility Model Content

[0007] As a preferred technical solution of the utility model, the two clamping plates are both in the shape of circular arcs with openings facing each other, and the clamping plates are both made of spring steel.

[0008] As a preferred technical solution of the utility model, the adjustment assembly includes an adjustment rod rotatably mounted on a workbench, and the adjustment rod is provided with two sections of threads with opposite rotation directions, the two clamping plates are respectively mounted on the two sections of threads, and a sliding rod with an axis parallel to the adjustment rod is also installed on the workbench, and the two clamping plates are both slidably mounted on the sliding rod.

[0009] As a preferred technical solution of the utility model, a sliding hole is provided on the workbench, the limiting assembly further comprises a sliding block slidably mounted inside the sliding hole, and the limiting rod is mounted on the sliding block.

[0010] As a preferred technical solution of the utility model, the limiting rod is installed on the sliding block through threaded fitting.

[0011] As a preferred technical solution of the utility model, the limiting assembly also includes a plurality of push rods rotatably mounted on the ends of the limiting rods, and the free ends of the push rods are provided with Y-shaped openings.

[0012] As a preferred technical solution of the utility model, an adjusting sleeve is threadedly matched on the limiting rod, and the outer edge of the adjusting sleeve is in contact with the plurality of limiting rods.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The flange side hole is limited and fixed to avoid the flange from rotating during the grinding process, which greatly improves the grinding effect and efficiency.

[0015] The flange can be polished through one-time fixation, which improves the polishing efficiency and reduces the damage of the tool, thereby reducing the production efficiency of the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , a limited lathe tool comprises a workbench 1, the workbench 1 is provided with a flange clamping assembly, the flange clamping assembly comprises two clamping plates 3 with adjustable spacing, and also comprises at least two support rods 4 installed on the workbench 1 for supporting the flange. When in use, the flange to be polished is placed on the support rod 4 of the workbench 1, and the adjustment assembly comprises an adjusting rod 2 rotatably mounted on the workbench 1, and the adjusting rod 2 is provided with two sections of threads with opposite rotation directions, and the two clamping plates 3 are respectively cooperated and installed on the two sections of threads, and the workbench 1 is also equipped with a sliding rod 9 whose axis is parallel to the adjusting rod 2, and the two clamping plates 3 are slidably mounted on the sliding rod 9, and then the adjusting rod 2 is rotated, and the cooperation between the two sections of threads on the adjusting rod 2 and the clamping plates 3 is realized to drive the spacing of the two clamping plates 3 to be quickly adjusted, and the flange has the function of centering the flange during the adjustment process, so the flange to be polished can be effectively and quickly fixed, and can be suitable for flange processing of different sizes, and the versatility of the equipment is higher. The plates 3 are all arc-shaped with openings facing each other, and the clamping plates 3 are all made of spring steel. The arc-shaped clamping plates 3 have the effect of being more closely attached to the outer wall of the flange. At the same time, the clamping plates 3 made of spring steel have a certain spring. When flanges of different diameters are fixed, the fixing effect is better. During the grinding process after the flange is fixed, the flange may rotate due to the large grinding force, resulting in a significant reduction in the grinding effect. At the same time, after long-term practical use, the wear of the clamping mechanism will increase, reducing its service life. At this time, a limiting component is also included, and the limiting component includes a limiting rod 6 that can limit the side hole of the flange, and the top end of the limiting rod 6 is lower than the upper surface of the flange. The limiting rod 6 can fix the flange in the radial direction, improve the fixing effect of the flange, and greatly improve the grinding effect. At the same time, limiting the top end of the limiting rod 6 can avoid damage to the grinding tool during grinding, and the flange can be ground by one-time fixing, which improves the grinding efficiency and reduces the damage to the tool.

[0022] As can be seen from the accompanying drawings, a sliding hole 5 is provided on the workbench 1, and the limiting assembly also includes a slider 10 slidably installed inside the sliding hole 5, and the limiting rod 6 is installed on the slider 10. During actual use, due to the different sizes of flanges, it is only necessary to slide the slider 10 inside the sliding hole 5 according to the required position, which is practical for the use of flanges of different sizes and more convenient to adjust. The limiting rod 6 is installed on the slider 10 through threaded cooperation. In order to improve the fixing effect of flanges of different sizes, the height of the limiting rod 6 is adjusted through threads, thereby further improving the versatility of the device.

[0023] As can be seen from the accompanying drawings, the limiting assembly also includes a plurality of push rods 8 rotatably mounted at the end of the limiting rod 6, and the free end of the push rod 8 is provided with a Y-shaped opening, the number of the push rods 8 is at least two, and the plurality of push rods 8 are distributed in a circular array along the axial direction of the adjusting rod 2. When in use, the inclination angle of the plurality of push rods 8 is controlled by the adjusting sleeve 7, and the limiting rod 6 is threadedly fitted with the adjusting sleeve 7. The outer edge of the adjusting sleeve 7 is in contact with the plurality of limiting rods 6, and is adjusted according to the size of the side hole on the polished flange, so that the Y-shaped openings of the plurality of push rods 8 pass through the side hole of the flange and are fixed to it, which can not only cope with the side hole sizes of flanges of different sizes, but also keep the flange fixed during the polishing process to ensure the polishing effect.
