Description

Technical Field

[0001] The utility model belongs to the technical field of fixtures, and in particular relates to a turning fixture. Background Art

[0002] In traditional turning processes, workpiece fixturing and clamping have always been critical. Early turning fixtures had relatively simple structures and limited functionality, often adapting only to workpieces of specific shapes and sizes, lacking flexibility and versatility. With the continuous development of industry, the manufacturing industry's demand for machining accuracy, efficiency, and diversified production is increasing. Traditional fixtures are gradually revealing their limitations when faced with complex workpieces or high-precision machining requirements.

[0003] For example, the publication number in the related field is CN218891462U, and the patent name is: A turning fixture, whose structure specifically includes a fixture disk, on which a cross groove is provided; a transverse fixture and a longitudinal fixture, with two transverse fixtures provided in the transverse groove of the cross groove, and two longitudinal fixtures provided in the longitudinal groove of the cross groove; a driving structure; the clamping surfaces of the transverse fixture and the longitudinal fixture are both provided with clamps, and the clamping surfaces of the transverse fixture and the longitudinal fixture are both provided with clamp mounting slots, the ends of the clamps are fixedly connected with locking blocks, the heads of the clamp mounting slots are provided with connecting slots matching the locking blocks, and the ends of the locking blocks are provided with locking screws. The utility model can realize the detachable assembly and disassembly of the clamps by providing clamp mounting slots on the clamping surfaces of the transverse fixture and the longitudinal fixture, and cooperating with the connecting slots, locking blocks and locking screws provided between the clamps and the clamp mounting slots.

[0004] Although the turning fixture in the above-mentioned prior art is convenient for replacing damaged clamps, its adjustment method is symmetrical movement adjustment, and clamps at four positions, namely, up, down, left and right, are used to clamp the workpiece. This fixed symmetrical mode makes it impossible for the fixture to flexibly and accurately adjust the position of the clamp according to the specific shape and special structure of the workpiece when facing workpieces of various shapes. For example, when encountering a workpiece with irregular protrusions, grooves or special-shaped contours, it is difficult for the clamps in a fixed position to completely fit the surface of the workpiece, and it is impossible to achieve a stable and uniform clamping. This may not only cause the workpiece to loosen during the turning process, affecting the processing accuracy, but may even cause safety accidents, and cannot meet the existing use requirements for clamping special-shaped workpieces. To this end, a turning fixture is provided to solve the above-mentioned technical problems. Utility Model Content

[0005] With regard to the turning fixtures in the prior art, there is a problem that the position of the clamp cannot be flexibly adjusted according to the specific shape and special structure of the workpiece, and there are certain limitations in use, which cannot meet the needs of use.

In actual application, the adjustable clamp can be flexibly placed in the corresponding T-shaped slide according to the specific contour of the workpiece, so as to adapt to various types of special-shaped contour workpieces, including workpieces with complex curves and special protrusions or groove structures. By reasonably adjusting the position of the clamp, a stable clamp is achieved, which greatly broadens the scope of application of the clamp and meets the processing needs of diversified workpieces in modern manufacturing. It successfully solves the limitation problem that the existing turning fixture cannot flexibly adjust the position of the clamp according to the shape and special structure of the workpiece. Its specific technical solution is as follows:

[0011] Compared with the prior art, the turning fixture of the present invention has the following beneficial effects:

[0012] This new fixture utilizes a bidirectional screw with forward and reverse threads, and two equally spaced T-shaped slots on two movable platforms, within which adjustable clamps can be removably mounted.

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

[0021] In this embodiment, front, back, left, right, up and down are represented by Figure 1 Describes the datum. Figures 1-6 , the utility model provides a technical solution:

[0022] A turning fixture, such as Figure 1 As shown, it includes a mounting plate 1 with a connecting sleeve 12 on the left side, a slide groove 11 is provided on the right surface of the mounting plate 1, and a forward and reverse bidirectional screw 2 with a handwheel 21 on the top is rotatably installed in the slide groove 11. Two movable platforms 3 are symmetrically screwed on the outer surface of the forward and reverse bidirectional screw 2. The movable platforms 3 are slidably installed in the slide groove 11, and a plurality of T-shaped slide grooves 31 are equidistantly penetrated on the upper surface of the movable platform 3. The T-shaped slide groove 31 passes through the right surface of the movable platform 3. An adjustable clamp 4 is detachably installed in the T-shaped slide groove 31, and the number of adjustable clamps 4 assembled is four;

[0023] It should be noted that, combined with Figure 4 and Figure 3 As shown, the adjustable clamp 4 includes an I-shaped block 41, which is slidably installed in the corresponding T-shaped slot 31. A mounting hole 411 is opened on the right surface of the I-shaped block 41, and a locking bolt A412 is threadedly installed through the mounting hole 411. The left end of the locking bolt A412 is tightly pressed against the corresponding T-shaped slot 31 to fix the position of the I-shaped block 41. A support block 42 is integrally formed on the lower surface of the I-shaped block 41, and a contact block 43 is installed on the right surface of the support block 42.

[0024] During actual use, according to the contour shape of the workpiece to be clamped, the corresponding locking bolt A412 can be loosened, and the four I-blocks 41 can be slid in the T-shaped slot 31 or pulled out of the T-shaped slot 31 and moved to other T-shaped slots 31 for use, so that the four I-blocks 41 are located on the outside of the workpiece, and the four contact blocks 43 are arranged in pairs above and below the workpiece and fit into the workpiece. After that, the position of the locking bolt A412 is tightened, and after the positions of the I-blocks 41 and the contact blocks 43 are fixed, the two movable platforms 3 are driven inward by the forward and reverse bidirectional screws 2, so that the workpiece is clamped and fixed by the contact blocks 43.

[0025] It is worth noting that after adjusting the position of the I-shaped block 41, in order to facilitate the adjustment of the contact block 43 and the contact surface of the clamped workpiece, Figure 4 and Figure 5 As shown, an adapter ring 421 is fixedly installed on the right surface of the support block 42, and an adapter groove 432 is formed on the left surface of the contact block 43. The adapter ring 421 and the adapter groove 432 are rotatably connected. A convex hole 431 is formed through the right surface of the contact block 43. A locking bolt B433 for fixing the contact block 43 is threadedly installed through the right surface of the support block 42. The locking bolt B433 passes through the convex hole 431, the adapter groove 432 and the adapter ring 421.

[0026] When adjusting the position of the I-block 41, slightly loosen the locking bolt B433 so that the contact block 43 can rotate on the outer surface of the adapter ring 421. In this way, after the I-block 41 is adjusted to the appropriate position, the position of the contact block 43 can be rotated and adjusted according to the shape of the workpiece so that it can reach the optimal angle of contact with the workpiece, which can effectively compensate for the clamping gap or uneven force problems that may be caused by the irregular shape of the workpiece.

[0027] In addition, combined Figure 1 and Figure 6 As shown, the lathe main shaft 5 is installed in the connecting sleeve 12, and the pin rod 51 is installed between the lathe main shaft 5 and the connecting sleeve 12. This clamp is used by connecting the connecting sleeve 12 to the lathe main shaft 5, and the installation of the pin rod 51 is to fix the connecting sleeve 12 and the lathe main shaft 5.

[0028] Finally, in order to further strengthen the fixing effect between the connecting sleeve 12 and the main shaft 5 of the lathe, as shown in FIG. Figure 6 As shown, a positioning bolt 121 is threadedly installed between the connecting sleeve 12 and the lathe main shaft 5. After the positioning bolt 121 passes through the pin rod 51, the positioning bolt 121 and the pin rod 51 are distributed in a cross shape, respectively fixing the connecting sleeve 12 and the lathe main shaft 5, thereby further strengthening the connection effect between the two.
