Description

Technical Field

[0001] This invention relates to the field of machining tooling, specifically to a tooling for rapid positioning of the rotation angle of an aluminum profile extrusion die and its usage method. Background Technology

[0002] Aluminum profile extrusion dies need to be positioned at a fixed rotation angle on CNC milling machines and cannot be directly machined. When positioning them, the rotation angle of the extrusion die needs to be known, or the positive rotation angle of the extrusion die needs to be parallel to the X-axis of the CNC machine tool. There are two ways to obtain this angle data: one is to use a dial indicator or micrometer to detect the workpiece rotation angle, but the accuracy will have an error of about 0.01mm; the other is to use the electronic probe equipped on the CNC machine tool to measure the workpiece rotation angle, with an accuracy of about 0.003mm, which is much higher than the former. This is very important for precision machining.

[0003] Before using an electronic probe to measure the workpiece rotation angle, the mold needs to be initially placed and positioned manually, and the approximate workpiece rotation angle after the initial placement and positioning should be given so that the rotation angle is as close as possible to the standard value, in order to avoid large adjustments to the mold position later. The traditional adjustment method is: manually determine the rotation angle of the mold using measuring tools, and further adjust the mold according to the determined rotation angle. After repeating this process multiple times, the rotation angle of the mold will gradually approach the standard value, and then the electronic probe can be used to measure it.

[0004] The problem with traditional adjustment methods is that the entire adjustment process requires staff to repeatedly adjust the model itself, making the workflow cumbersome.

[0005] To address this, we propose a tooling for rapid positioning of the rotation angle of an aluminum profile extrusion die. Summary of the Invention

[0006] To address the problem that existing adjustment methods require staff to repeatedly adjust the model itself throughout the adjustment process, resulting in a cumbersome workflow.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tooling for rapid positioning of the rotation angle of an aluminum profile extrusion die, comprising an external limiting member disposed on the side of an aluminum profile die processing platform, wherein an aluminum profile die limiting member is disposed inside the external limiting member for positioning the aluminum profile die placed on the aluminum profile die processing platform, the aluminum profile die limiting member comprising a sliding plate and a locking limiting block, the sliding plate being disposed inside the external limiting member and constrained by the external limiting member, the locking limiting block being located on one side of the sliding plate, and a sliding plate limiting member for restricting the falling of the aluminum profile die limiting member being disposed in the middle of the external limiting member;

[0008] The locking and limiting block moves along the slide plate along the external limiting component to adjust its position until it corresponds to the reserved notch on the outside of the aluminum profile mold, thereby adjusting and limiting the aluminum profile mold.

[0009] Preferably, the external limiting component includes a limiting seat body, a sliding groove in the middle of the limiting seat body, bolt grooves on both sides of the limiting seat body, and bolts disposed in the bolt grooves for fixing the limiting seat body. The bolts fix the limiting seat body to the side of the aluminum profile mold processing platform through the bolt grooves. The aluminum profile mold limiting component is sleeved in the sliding groove and is restricted to vertical displacement by the sliding groove.

[0010] Preferably, the surfaces of both the slide groove and the slide plate are polished, the slide plate and the slide groove fit together, and a notch is provided in the middle of the upper end of the slide groove for the installation of the slide plate restraint.

[0011] Preferably, each corner of the slide groove is provided with an arc-shaped groove that extends through the slide groove.

[0012] Preferably, the locking and limiting block has a two-section design. The lower section of the locking and limiting block is a solid cube, and the upper section of the locking and limiting block protrudes relative to the lower section, and the protruding part is an arc shape that matches the reserved notch in the aluminum profile mold.

[0013] Preferably, the aluminum profile mold has a corresponding notch in the middle, and the locking block has a corresponding notch in the middle of the arc-shaped protrusion.

[0014] Preferably, the skateboard limiting component includes a base fixed to the outside of the upper notch of the slide groove, a movable rod sleeved inside the base, a rubber roller mounted on the end of the movable rod via a pivot for limiting the skateboard's descent, and a spring sleeved outside the rubber roller and in contact with the rubber roller and the base.

[0015] Preferably, the surface of the rubber roller is provided with several sets of protrusions, the several sets of protrusions are arranged at equal intervals on the surface of the rubber roller, and the surface of each set of protrusions is ground.

[0016] Preferably, the skateboard limiter further includes a rotating handle fixed to the end of the movable rod for the operator to grip.

[0017] A method for using a quick-positioning tooling for rotating the aluminum profile extrusion die, the method comprising:

[0018] A. Install external limiting components and fix the limiting seat body to the side of the aluminum profile mold processing platform through the cooperation of bolt slots and bolts;

[0019] B, Place the aluminum profile mold limiting component.

[0020] B1. Insert the slide into the groove;

[0021] B2, by rotating the handle, the movable rod is rotated, causing the rubber roller to rotate to a vertical position. In the vertical position, the rubber roller is in contact with the skateboard, restricting the skateboard from falling.

[0022] C, Place the aluminum profile mold to be positioned;

[0023] C1, Place the aluminum profile mold onto the aluminum profile mold processing platform;

[0024] C2, make the first position adjustment of the aluminum profile mold so that the notch reserved on the upper part of the aluminum profile mold coincides with the protruding part of the locking limit block in the vertical view.

[0025] D, Alignment and Positioning;

[0026] D1, by rotating the handle, the movable rod is rotated, causing the rubber roller to rotate to a horizontal state. The rubber roller in the horizontal state releases the restriction on the slide plate to fall, and falls along the slide groove at a controllable speed until the protruding part of the locking block is embedded into the pre-reserved notch on the upper part of the aluminum profile mold.

[0027] D2. Make a second position adjustment to the aluminum profile mold so that the notch reserved on the upper part of the aluminum profile mold fits with the protruding part of the locking limit block, and align the corresponding engraving at the notch of the aluminum profile mold with the corresponding engraving at the middle of the arc-shaped protruding part of the locking limit block.

[0028] E. Remove the external limiting component.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. In this invention, by cooperating with the external limiting component and the aluminum profile mold limiting component, the first position adjustment makes the pre-reserved notch on the upper part of the aluminum profile mold coincide with the protruding part of the locking limiting block in a vertical view. The second position adjustment makes the pre-reserved notch on the upper part of the aluminum profile mold fit with the protruding part of the locking limiting block, so that the corresponding engraving at the pre-reserved notch of the aluminum profile mold is aligned with the corresponding engraving at the middle of the arc-shaped protruding part of the locking limiting block. The rotational positioning of the aluminum profile mold before inspection can be completed by two adjustments, which solves the problem of cumbersome workflow in the traditional positioning method.

[0031] 2. In this invention, the notch reserved on the upper part of the aluminum profile mold fits into the protruding part of the locking and limiting block. When adjusting the position of the aluminum profile mold, the locking and limiting block can be used as the rotation axis for further rotational fine adjustment.

[0032] 3. In this invention, a sliding plate limiter is added. In the vertical state, the sliding plate limiter can restrict the falling of the aluminum profile mold limiting component, which facilitates the setting of the aluminum profile mold. In the horizontal state, the sliding plate limiter can slow down the falling speed of the sliding plate, which facilitates the adjustment of the position of the aluminum profile relative to the locking limiting block.

[0040] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Reference Figures 1-5A quick-positioning fixture for rotating aluminum profile extrusion molds includes an external limiting component 1 disposed on the side of an aluminum profile mold processing platform. The external limiting component 1 contains an aluminum profile mold limiting component 2 for positioning the aluminum profile mold placed on the processing platform. The aluminum profile mold limiting component 2 includes a sliding plate 21 and a locking limiting block 22. The sliding plate 21 is disposed inside the external limiting component 1 and is constrained by it. The locking limiting block 22 is located on one side of the sliding plate 21 and moves along the external limiting component 1 with the sliding plate 21 to adjust its position to correspond to a pre-reserved notch on the outside of the aluminum profile mold for adjustment and limiting. The external limiting component 1 also has a sliding plate limiting component 3 in the middle to restrict the falling of the aluminum profile mold limiting component 2.

[0042] The external limiting component 1 includes a limiting seat body 11, a sliding groove 12 opened in the middle of the limiting seat body 11, bolt grooves 13 opened on both sides of the limiting seat body 11, and bolts 14 set in the bolt grooves 13 for fixing the limiting seat body 11. The bolts 14 fix the limiting seat body 11 to the side of the aluminum profile mold processing platform through the bolt grooves 13. The aluminum profile mold limiting component 2 is sleeved in the sliding groove 12 and is restricted by the sliding groove 12 to adjust its position by vertical displacement.

[0043] Both the surfaces of the slide groove 12 and the slide plate 21 are polished. The slide plate 21 and the slide groove 12 fit together. The corners of the slide groove 12 are provided with arc-shaped grooves that penetrate the slide groove 12. The arc-shaped grooves prevent the corners of the slide plate 21 from colliding with the slide groove 12 during the insertion process. At the same time, they allow external air to be quickly replenished between the slide groove 12 and the slide plate 21, preventing the slide groove 12 and the slide plate 21 from being completely attached and generating large friction due to air pressure difference. This ensures that the slide plate 21 can slide normally in the slide groove 12.

[0044] The locking and limiting block 22 has a two-section design. The lower section of the locking and limiting block 22 is a solid cube. The solid cube has a large mass, which can provide sufficient downward pressure and prevent easy changes in the setting state. The upper section of the locking and limiting block 22 protrudes relative to the lower section, and the protruding part is an arc shape that matches the aluminum profile mold. When the protruding arc part of the locking and limiting block 22 is aligned with the arc part reserved on the aluminum profile mold, it means that the aluminum profile mold is basically in place. Therefore, during the placement of the aluminum profile mold, there is no need to make repeated adjustments. It is only necessary to make the protruding arc part of the locking and limiting block 22 aligned with the arc part reserved on the aluminum profile mold.

[0045] The upper middle part of the slide groove 12 has a notch for mounting the slide plate limiter 3. The slide plate limiter 3 includes a base 31 fixed to the outside of the upper notch of the slide groove 12, a movable rod 32 sleeved inside the base 31, a rubber roller 33 mounted on the end of the movable rod 32 via a pivot to limit the fall of the slide plate 21, and a spring 34 sleeved outside the rubber roller 33 and in contact with the rubber roller 33 and the base 31. The slide plate limiter 3 can switch between vertical and horizontal states. In the vertical state, the slide plate limiter 3 can limit the fall of the aluminum profile mold limiter 2. In the horizontal state, the slide plate limiter 3 can slow down the fall speed of the slide plate 21.

[0046] The surface of the rubber roller 33 is provided with several sets of protrusions, which are evenly spaced on the surface of the rubber roller 33. Each set of protrusions is polished. In the vertical state, two sets of protrusions can simultaneously abut against the surface of the skateboard 21 to form two contact points, thereby increasing the contact area and improving the contact friction. This allows the rubber roller 33 to limit the sliding of the skateboard 21 through friction. In the horizontal state, the downward movement of the skateboard 21 will drive the rubber roller 33 to rotate. During the rotation of the rubber roller 33, the protrusions will push the movable rod 32 to move laterally. During the lateral movement of the movable rod 32, the spring 34 will continuously extend and retract. The continuous extension and retraction of the spring 34 limits the falling speed of the skateboard 21 and prevents the skateboard 21 from falling directly.

[0047] The skateboard limiting component 3 also includes a rotating handle 35 fixed to the end of the movable rod 32 for the operator to hold. When switching the setting angle of the rubber roller 33, the operator can conveniently rotate the movable rod 32 by rotating the handle 35, thereby causing the rubber roller 33 to switch from a horizontal to a vertical state, or from a vertical state to a horizontal state.

[0048] The device is used as follows: Install the external limiting component 1, and fix the limiting seat body 11 to the side of the aluminum profile mold processing platform through the cooperation of the bolt groove 13 and the bolt 14.

[0049] Place the aluminum profile mold limiting part 2, insert the slide plate 21 into the slide groove 12, and rotate the movable rod 32 by rotating the handle 35, so that the rubber roller 33 rotates to the vertical position. The rubber roller 33 in the vertical position abuts against the slide plate 21, restricting the slide plate 21 from falling.

[0050] Place the aluminum profile mold to be positioned, place the aluminum profile mold on the aluminum profile mold processing platform, and make the first position adjustment of the aluminum profile mold so that the pre-reserved notch on the upper part of the aluminum profile mold coincides with the protruding part of the locking limit block 22 in the vertical view.

[0051] Alignment and positioning: Rotate handle 35 to drive movable rod 32 to rotate, so that rubber roller 33 rotates to a horizontal state. In the horizontal state, rubber roller 33 releases the restriction on the falling of slide plate 21 and falls along slide groove 12 at a controllable speed until the protruding part of locking limit block 22 is embedded into the pre-reserved notch on the upper part of aluminum profile mold. The aluminum profile mold is then adjusted for the second time so that the pre-reserved notch on the upper part of aluminum profile mold fits with the protruding part of locking limit block 22, and the corresponding engraving at the pre-reserved notch of aluminum profile mold is aligned with the corresponding engraving at the middle of the arc-shaped protruding part of locking limit block 22.

[0052] Finally, remove the external limiting component.
