[0002] For milling of box-shaped parts, especially cast box blanks, due to the large machining allowance and geometric dimensional error, it is necessary to mark horizontal reference lines around the box and then use spiral pads to level and align it in the machining center before machining. Leveling requires adjusting the height of the reference surface in two directions to make the horizontal reference line parallel to the milling machine table. The alignment process is time-consuming, labor-intensive, inefficient, and labor-intensive. Summary of the Invention

[0003] This utility model provides a tooling for milling box-shaped parts to overcome the shortcomings of the prior art.

[0004] The technical solution adopted by this utility model is: a tooling for milling box parts, including a rectangular base and a rectangular adjustment frame. A rotating shaft is horizontally mounted on the top surface of the rear end of the rectangular base. Mounting seats are symmetrically mounted on both ends of the rotating shaft. Arc-shaped guide rails are symmetrically provided on the opposite surfaces of the two mounting seats.

[0005] The rectangular base has a worm gear horizontally mounted at the front end and a lead screw mounted vertically. The upper end of the lead screw is threaded with a nut and the lower end is mounted with a worm wheel. The worm gear meshes with the worm wheel. The upper end of the nut is slidably connected to a hinge seat, and a drive mechanism is hinged on the hinge seat.

[0006] The rectangular adjustment frame has a horizontal support shaft 1 at the center of its front end and two symmetrically distributed support shafts 2 at its rear end. The two support shafts 2 are slidably connected to the arc-shaped guide rail via sliders fixed at their ends. The support shaft 1 is inserted into the output end of the drive mechanism. The drive mechanism drives the rectangular adjustment frame to rotate left and right along the arc-shaped guide rail via the support shaft 1. At the same time, the worm gear drives the front end of the rectangular adjustment frame to move up and down and the rear end to rotate around the axis of rotation via the drive mechanism. Horizontal sliding grooves are provided on the left and right sides of the rectangular base, and a height gauge is slidably connected to the horizontal sliding grooves.

[0007] A locking block is slidably connected to the mounting base, and the arc-shaped surface of the locking block is opposite to the arc-shaped guide rail. Two bolts pass through the upper and lower ends of the locking block and are threadedly connected to the mounting base to clamp and lock the slider and the arc-shaped guide rail.

[0008] It also includes a locking mechanism for locking the mounting bracket. The locking mechanism includes a pull rod, a T-block, and a locking screw. The T-block is fitted into a T-slot at the rear end of the rectangular base and is hinged to the lower end of the pull rod. The upper end of the pull rod is fitted into a T-slot on the outer end face of the mounting bracket via a T-head. The locking screw is threaded onto the T-block and abuts against the bottom surface of the T-slot.

[0009] The drive mechanism consists of a primary worm gear mechanism, a secondary lead screw nut, and a tertiary cylindrical cam mechanism. The primary worm gear mechanism drives the lead screw of the secondary lead screw nut to rotate, which in turn drives the lead screw nut of the secondary lead screw nut to move. The movement of the lead screw nut drives the output shaft of the tertiary cylindrical cam mechanism to rotate. The support shaft is inserted and connected to the output shaft.

[0011] 1. This utility model organically combines the X-axis and Y-axis leveling mechanisms, and through cooperation with the height gauges set on both sides of the leveling mechanism, it realizes the completion of X-axis leveling on the basis of Y-axis leveling, ensuring that the horizontal baseline engraved around the box is accurately parallel to the milling machine table.

[0012] 2. This utility model adopts worm gear drive, which realizes self-locking at any position during the leveling process. The whole leveling process is convenient, time-saving, labor-saving and highly efficient.

[0020] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in detail with reference to specific embodiments.

[0021] A tooling for milling box-shaped parts includes a rectangular base 1 and a rectangular adjustment bracket 2. A rotating shaft 3 is horizontally mounted on the top surface of the rear end of the rectangular base 1. Mounting seats 4 are symmetrically fitted at both ends of the rotating shaft 3. Arc-shaped guide rails 4-1 are symmetrically provided on the opposite surfaces of the two mounting seats 4.

[0022] The rectangular base 1 has a worm 5 horizontally mounted at the front end and a lead screw 6 vertically mounted. The lead screw 6 has a nut 7 threadedly connected to the upper end and a worm wheel 8 mounted at the lower end. The worm 5 meshes with the worm wheel 8. The nut 7 has a hinge seat 9 slidably connected to the upper end, and a drive mechanism 10 is hinged on the hinge seat 9.

[0023] The rectangular adjustment frame 2 has a horizontal support shaft 2-1 at the center of its front end and two symmetrically distributed support shafts 2-2 at its rear end. The two support shafts 2-2 are slidably connected to the arc-shaped guide rail 4-1 through sliders 2-3 fixed at their ends. The support shaft 2-1 is inserted into the output end of the drive mechanism 10. The drive mechanism 10 drives the rectangular adjustment frame 2 to rotate left and right along the arc-shaped guide rail 4-1 through the support shaft 2-1. At the same time, the worm gear 5 drives the front end of the rectangular adjustment frame 2 to move up and down and the rear end to rotate around the rotating shaft 3 through the drive mechanism 10. The rectangular base 1 has horizontal sliding grooves 1-1 on its left and right sides, and a height gauge 11 is slidably connected to the horizontal sliding grooves 1-1.

[0024] In the above embodiments, the horizontal groove 1-1 is preferably a T-shaped groove, and the inner side of the height gauge 11 base is provided with a T-shaped slider 2-3 that is adapted to slide and connect with the T-shaped groove, which facilitates the assembly and disassembly of the height gauge 11.

[0025] In the above embodiment, a locking block 12 is slidably connected to the mounting base 4, and the arc-shaped surface of the locking block 12 is opposite to the arc-shaped guide rail 4-1. Two bolts 13 are threadedly connected to the mounting base 4 through the upper and lower ends of the locking block 12, thereby clamping and locking the slider 2-3 and the arc-shaped guide rail 4-1.

[0026] The above embodiment also includes a locking mechanism 14 for locking the mounting bracket 4. The locking mechanism 14 includes a pull rod 14-1, a T-block 14-2, and a locking screw 14-3. The T-block 14-2 is fitted into the T-slot at the rear end of the rectangular base 1 and is hinged to the lower end of the pull rod 14-1. The upper end of the pull rod 14-1 is fitted into the T-slot on the outer end face of the mounting bracket 4 through a T-head. The locking screw 14-3 is threaded onto the T-block 14-2 and abuts against the bottom surface of the T-slot.

[0027] In the above embodiment, the drive mechanism 10 consists of a primary worm gear mechanism 10-1, a secondary lead screw nut 10-2, and a tertiary cylindrical cam mechanism 10-3. The primary worm gear mechanism 10-1 drives the lead screw of the secondary lead screw nut 10-2 to rotate, thereby causing the lead screw nut of the secondary lead screw nut 10-2 to move. This movement of the lead screw nut drives the output shaft of the tertiary cylindrical cam mechanism 10-3 to rotate. The support shaft 2-1 is inserted and connected to the output shaft. In actual use, the drive mechanism 10 is manually driven by connecting a crank handle to the worm of the primary worm gear mechanism 10-1.

[0028] In the above embodiment, two height gauges 11 are slidably connected on the left horizontal slide groove 1-1, and one height gauge 11 is slidably connected on the right horizontal slide groove 1-1.

[0029] In practical use, first place the above-mentioned fixture on the milling machine fixture table for alignment and fixation. Then place the box 15 to be processed with the reference line 16 on the upper end of the rectangular adjustment frame 2, and align the box with the height gauge 11 on one side and fix the box to the rectangular adjustment frame 2. Then slide the two height gauges 11 on the left side to the front and rear ends of the box 16 respectively, measure the height difference of the reference line at the front and rear ends of the box, and then rotate the worm gear 5 to make the swing adjustment frame 2 swing up and down, so that the height measured by the height gauges 11 at the front and rear ends of the box 16 is consistent. At this point, the heights of the front and rear ends of the reference line 17 are consistent, and the Y-axis leveling is achieved. Tighten the locking screws 14-3 of the locking mechanism 14 to fix the position of the mounting frame 4 and the base. Next, slide the height gauge 11 on the right side of the housing to the same position as the height gauge on the left side of the housing. Measure the height difference between the two reference lines 17 on both sides using the height gauges 11. Then, use the drive mechanism 10 to rotate the rectangular adjustment frame 2 until the heights of the reference lines 17 on both sides are consistent. After verifying accuracy using the two height gauges 11 on the left side, achieve X-axis leveling. Then, thread the two bolts 13 through the upper and lower ends of the locking block 12 to the mounting bracket 4, and lock the slider 2-3 to the arc-shaped guide rail 4-1 to fix the rectangular adjustment frame 2, ensuring tooling stability during milling and improving milling quality. Slide the two height gauges 11 out from the horizontal slide grooves 1-1 on both sides, and start the milling machine to complete the cutting above the reference line 16 of the housing 15 and the milling of the four sides of the housing.
