Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically a quick positioning fixture for flange boring. Background Technology

[0002] Flanges are standardized mechanical parts used in the industrial field to connect pipes, valves, and equipment. They achieve reliable sealing through bolt fixing and mating with gaskets. In the production and processing of some precision flanges, when precision boring the flange's inner hole or connecting hole, a quick-positioning fixture is required for fixing and positioning the flange workpiece.

[0003] However, in actual use, most fast positioning fixtures for flange boring adopt a simple fixation method with two-sided positioning. Due to the circular structure of the outer side of the flange, the two-sided positioning method has few fixed positions on the outer side of the workpiece, resulting in insufficient stability of the workpiece during the machining process and easy displacement. This is a shortcoming and makes it inconvenient to quickly position the flange workpiece during boring.

[0004] Now, a novel rapid positioning fixture for flange boring is proposed to address the above-mentioned shortcomings. Utility Model Content

[0007] As a further technical solution of this utility model, scale lines are respectively provided on both sides of the rear end and front end of the top of the top plate.

[0008] As a further technical solution of this utility model, the three sets of mounting grooves are distributed in a ring at equal intervals inside the top of the base, and the three sets of movable grooves are distributed in a ring at equal intervals inside the top of the top plate, with the movable grooves penetrating the interior of the top plate.

[0009] As a further technical solution of this utility model, the top end of the connecting block penetrates the interior of the movable groove, and the bottom end of the connecting bolt penetrates the interior of the top end of the positioning foot and is rotatably connected in the connecting hole.

[0010] As a further technical solution of this utility model, a number of scraping brushes are fixed on the left side inside the movable groove, and a number of scraping brushes are fixed on the right side inside the movable groove. Two sets of drainage holes are opened at the bottom end of the mounting groove, and the drainage holes penetrate through the interior of the bottom end of the base.

[0011] As a further technical solution of this utility model, the plurality of scraping brushes one and the plurality of scraping brushes two are distributed at equal intervals.

[0012] As a further technical solution of this utility model, mounting bolts are respectively provided at the four corners of the top of the top plate, and mounting holes are respectively opened inside the four corners of the top of the base.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides an embodiment: a quick positioning fixture for flange boring, including a base 2, a top plate 3 at the top of the base 2, three sets of mounting grooves 10 inside the top of the base 2, a lead screw 13 movably connected inside the three sets of mounting grooves 10, and a threaded sleeve 11 threadedly connected to the outside of the lead screw 13, the outside of the three sets of lead screws 13 respectively passing through the interior of the base 2 and fixed with a rotating handle 15, three sets of movable grooves 9 inside the top of the top of the top of the top plate 3, a connecting block 8 fixed to the top of the threaded sleeve 11, and a connecting hole 7 inside the top of the connecting block 8, three sets of positioning feet 4 at the top of the top of the top plate 3, slots 6 inside the bottom of the three sets of positioning feet 4, and connecting bolts 5 at the top of the three sets of positioning feet 4;

[0025] The top plate 3 has scale lines 16 on both sides of the rear end and front end. Three sets of mounting grooves 10 are distributed in a ring at equal intervals inside the top of the base 2. Three sets of movable grooves 9 are distributed in a ring at equal intervals inside the top of the top of the top plate 3. The movable grooves 9 penetrate the interior of the top plate 3. The top of the connecting block 8 penetrates the interior of the movable groove 9. The bottom of the connecting bolt 5 penetrates the interior of the top of the positioning foot 4 and is rotatably connected in the connecting hole 7.

[0026] Specifically, such as Figures 1-3 As shown, after placing the flange workpiece in the middle position at the top of the fixture, the lead screw 13 can be driven to rotate by rotating the three sets of rotating handles 15 respectively. When the lead screw 13 rotates, the threaded sleeve 11 connected by threads can drive the positioning feet 4 to move inward. By using the three sets distributed in a ring, the flange workpiece can be quickly fixed and positioned, and fixed in multiple directions, which improves the stability of the flange workpiece. At the same time, the three sets of adjustable positioning feet 4 can be used to adapt and fix some flange workpieces of different sizes. The overhead clamping leaves the bottom of the workpiece open, which is convenient for processing operations.

[0027] Several scraper brushes 18 are fixed on the left side inside the movable groove 9, and several scraper brushes 29 are fixed on the right side inside the movable groove 9. Two sets of drainage holes 12 are opened at the bottom end of the mounting groove 10, and the drainage holes 12 penetrate the interior of the bottom end of the base 2. Several scraper brushes 18 and several scraper brushes 29 are distributed at equal intervals.

[0028] Specifically, such as Figures 1-4 As shown, when the threaded sleeve 11 drives the connecting block 8 to move inside the movable groove 9, several soft scrapers 18 and 29 are respectively provided on both sides inside the movable groove 9 to assist in sealing the inside of the movable groove 9, reducing the entry of external boring debris into the fixture. At the same time, a drainage hole 12 is preset inside the base 2. After the coolant enters the fixture during the machining process, it can be directly discharged through the drainage hole 12 to prevent water accumulation inside the fixture.

[0029] Mounting bolts 17 are provided at the four corners of the top of the top plate 3, and mounting holes 14 are provided inside the four corners of the top of the base 2. The bottom end of the mounting bolts 17 passes through the interior of the top plate 3 and is rotatably connected in the mounting holes 14.

[0030] The base plate 1 is fixed on both sides of the bottom end of the base 2, and the base plate 1 has an inner hole.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, the fixture body has a detachable structure with upper and lower top plates 3 and base 2. After the four sets of mounting bolts 17 on the top of the top plate 3 are unscrewed from the mounting holes 14, the top plate 3 can be separated, the interior of the fixture can be opened, and the internal components of the fixture can be easily maintained. At the same time, the three sets of positioning feet 4 on the top of the fixture are also detachable, which is convenient for replacement.

[0032] Working Principle: When using this invention, the flange workpiece is placed in the middle position at the top of the fixture. Then, the lead screw 13 is driven to rotate by rotating three sets of handles 15. Simultaneously, the threaded sleeve 11, connected by threads, drives the positioning feet 4 to move inward. Using the three sets of ring-shaped handles, the flange workpiece can be quickly and securely fixed in multiple directions. During use, when the threaded sleeve 11 drives the connecting block 8 to move within the movable groove 9, several soft scrapers 18 and 19 are provided on both sides of the movable groove 9 to assist in sealing and preventing chipping inside. A drainage hole 12 is pre-set inside the base 2, allowing coolant entering the fixture during processing to be directly drained through the drainage hole 12, preventing water accumulation inside the fixture. The fixture body features a detachable structure with upper and lower top plates 3 and base 2. By unscrewing the four sets of mounting bolts 17 from the mounting holes 14 on the top plate 3, the top plate 3 can be separated, opening the fixture interior for convenient maintenance of the internal components.
