[0002] Turning and milling compound equipment is a comprehensive processing equipment for shaft sleeve workpieces, which can realize turning, milling and other comprehensive processing at the same time. The use of turning and milling compound equipment has become a processing method in the current mechanical processing field.

[0003] When machining shaft sleeve workpieces, turning and milling equipment generally adopts a one-clamp-one-top method to clamp the workpiece. When the workpiece is large and heavy, the following defects will occur:

[0004] 1. During the machining process, the rotation of the workpiece C-axis will generate a large load on the equipment, causing the equipment to issue a load warning, affecting the machining efficiency and quality of the workpiece;

[0005] 2. During the machining process, the workpiece rotates unstably, causing frequent tool chattering, resulting in low machining accuracy, increased surface roughness of the workpiece, and reduced machining quality of the workpiece.

[0006] At present, in order to solve the above problems, auxiliary tools are usually used to support the workpiece. For example, the Chinese utility model patent with publication number CN203775133U provides a center frame for a CNC lathe with an inclined guide rail. The center frame body is fixed to the machine tool guide rail by bolts, and the positioning plate is connected to the center frame body to center the workpiece. The workpiece is positioned by the needle bearing on the positioning plate to achieve support for the workpiece.

[0007] However, in the existing method, when adjusting the position of the center frame on the machine tool guide rail due to changes in the support position, the center frame needs to be frequently disassembled, which not only increases the processing difficulty and reduces the processing efficiency, but also causes irreversible damage to the accuracy of the machine tool guide rail during the support process, thereby reducing the service life of the equipment. Therefore, the existing method cannot meet the support requirements for the workpiece. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0033] refer to Figures 1 to 6 This embodiment provides an auxiliary support structure for a turning-milling composite device, including a support platform 10, a rolling support seat 20 and a workpiece support sleeve 30.

[0034] Among them, the rolling support seat 20 is arranged on the support platform 10, and the support platform 10 provides stable support for the rolling support seat 20; the rolling support seat 20 is movably connected to the workpiece support sleeve 30, and the workpiece support sleeve 30 is located above the rolling support seat 20, and the rolling support seat 20 provides stable support for the workpiece support sleeve 30. At the same time, the rolling support seat 20 is movably connected to the workpiece support sleeve 30, so that after the workpiece support sleeve 30 is connected to the workpiece, when the workpiece support sleeve 30 rotates with the workpiece during the processing, it can rotate relative to the rolling support seat 20, thereby achieving stable support for the workpiece processing process, avoiding equipment warnings and tool chattering during processing, ensuring stable and reliable workpiece processing, improving the processing quality of the workpiece, and meeting actual processing needs.

[0035] Among them, in order to provide stable support for the support platform 10 and to facilitate the adjustment of the position of the support platform 10 according to actual support requirements, the support platform 10 is selected to be coordinated with the lower turret 50; the characteristics of the lower turret 50 itself can be used to avoid damage to the equipment, and the position of the support platform 10 can also be changed by the movement of the lower turret 50, so as to realize the support needs of different positions of different workpieces and further meet the actual processing needs.

[0036] Specifically, refer to Figure 1 and Figure 2 The support platform 10 includes a support block 11 and a connecting section 12. The connecting section 12 is connected to one side of the support block 11. The connecting section 12 and the support block 11 can be optionally an integrated structure; the rolling support seat 20 can be optionally set on the other side of the support block 11. In order to ensure structural stability, the rolling support seat 20 is preferably set on the top end surface of the support block 11.

[0037] Further explanation, the support platform 10 can be optionally installed in conjunction with any tool holder 51 in the lower turret 50, so the structure of the connecting section 12 is designed according to the tool groove on the tool holder 51, and the end of the connecting section 12 and the connection end of the support block 11 are the reference positioning surface 13; at the same time, the length of the connecting section 12 is preferably less than the depth of the corresponding tool holder 51, to ensure that the reference positioning surface 13 can fit tightly with the top end face of the tool holder 51, thereby improving the stability of the support platform 10; the width of the connecting section 12 is less than the width of the corresponding tool holder 51, to avoid obstruction during processing of the upper turret, thereby ensuring processing efficiency and quality.

[0038] At the same time, the support platform 10 only occupies one tool seat 51 in the lower tool turret 50. When there is no need to support the workpiece, the tools in the other tool seats 51 in the lower tool turret 50 can be used normally. There is no need to frequently disassemble the support platform 10, thus meeting actual processing needs.

[0039] When the connecting section 12 is connected to the tool holder 51, it is preferably a disassembly connection. At this time, a clamping wedge 40 is selected to be set between the connecting section 12 and the tool groove, and then the clamping wedge 40 is connected to the tool holder 51 using a fastening screw 41 to squeeze the connecting section 12, thereby improving the connection stability of the connecting section 12. The number of fastening screws 41 can be selected to be multiple, and multiple fastening screws 41 are arranged at intervals along the length direction of the clamping wedge 40.

[0040] In order to improve the reliability of the support platform 10, it is preferred that the top end face of the support block 11 be kept horizontal with the axis of the workpiece. Therefore, when manufacturing the support platform 10, it is necessary to determine the angle between the reference positioning surface 13 and the top end face of the support block 11, so as to facilitate the rotation of the lower turret 50 to adjust the top end face of the support block 11 to be parallel to the axis of the workpiece.

[0041] For further explanation, see Figure 1 and Figure 3 The rolling support seat 20 needs to provide stable and steady support for the workpiece support sleeve 30, so the rolling support seat 20 is selected to include a bearing support 21, a positioning sleeve 22 and two bearings 23. A bearing limiting groove 24 is provided on the bearing support 21 along its length direction, and the two bearings 23 are arranged side by side in the bearing limiting groove 24 along the length direction of the bearing limiting groove 24; two positioning sleeve holes 25 are also provided on the bearing support 21, and the positioning sleeve holes 25 are arranged perpendicular to the bearing limiting groove 24, so that the positioning sleeve holes 25 pass through the two sides of the bearing limiting groove 24. At this time, the two bearings 23 are coaxially arranged with the corresponding positioning sleeve holes 25, and the positioning sleeve 22 passes through the positioning sleeve hole 25, so that the bearing 23 is rotatably connected to the bearing support 21 through the positioning sleeve 22; a pin hole is provided at the end of the positioning sleeve 22, and the positioning sleeve 22 is limited by the pin, thereby ensuring the reliability of the connection of the bearing 23.

[0042] At this time, two bearings 23 are used to support both sides of the workpiece support sleeve 30, so that the midline of the line connecting the centers of the two bearings 23 intersects with the center of the workpiece support sleeve 30, thereby achieving efficient and accurate positioning of the center position of the workpiece support sleeve 30, improving the support quality, and reducing the difficulty of positioning.

[0043] Therefore, it is preferred that the bearing support 21 is placed on the top end surface of the support block 11 when in use; the center position of the supported position is determined by moving the lower turret 50 up and down and left and right on the X-axis, and the support platform 10 is moved to the bottom of the workpiece support sleeve 30, and then the rolling support seat 20 is placed on the top end surface of the support block 11. During the upward movement of the lower turret 50, the two bearings 23 support the two sides of the workpiece support sleeve 30, and the bearing support 21 moves with the bearing 23, thereby completing the precise support of the workpiece support sleeve 30.

[0044] At the same time, when the workpiece does not need to be supported, the bearing support 21 can be removed from the support block 11, thereby lowering the height of the support platform 10 on the lower turret 50 to avoid affecting the operation of other tool bodies.

[0045] For further explanation, see Figure 1 and Figure 4 In order to prevent the rolling support seat 20 from deviating from the workpiece support sleeve 30 and causing the support to fail when the workpiece support sleeve 30 rotates with the workpiece, it is preferred to open an annular groove 31 on the outer wall of the workpiece support sleeve 30. The width of the annular groove 31 is adapted to the thickness of the bearing 23, so that the tops of the two bearings 23 are clamped in the annular groove 31 during actual processing, thereby limiting the bearings 23 and further ensuring that the rolling support seat 20 is stable and reliable during the processing.

[0046] The inner diameter of the workpiece support sleeve 30 can be selected according to the outer diameter of the workpiece. By sleeved on the outside of the workpiece, the rolling support seat 20 can be limited and the direct contact between the bearing 23 and the workpiece surface can be avoided to cause extrusion damage to the workpiece.

[0047] A ball bearing can be used as the bearing 23. As a wearing part, the bearing 23 adopts a standard part, which is convenient for purchasing spare parts and replacement, and the cost is low. When supporting different workpieces, it is only necessary to select a workpiece support sleeve 30 of corresponding size. The workpiece support sleeve 30 is simple to process and has low manufacturing cost, and is suitable for promotion and use, thereby further meeting actual processing needs.

[0048] Working process:

[0049] refer to Figure 5 First, the support platform 10 needs to be installed on the lower turret 50.

[0050] Specifically, the connecting section 12 is fastened to the corresponding tool holder 51 by means of the clamping wedge 40 and the fastening screw 41, while ensuring that the reference positioning surface 13 of the support block 11 is in close contact with the top end face of the tool holder 51, thereby further improving the stability of the connection between the support platform 10 and the tool holder 51, while ensuring that the top end face of the support block 11 is parallel to the main shaft axis.

[0051] The workpiece then needs to be clamped on the mill-turn machine.

[0052] Specifically, first, the workpiece support sleeve 30 is set on the part of the workpiece that does not participate in the processing, and then the chuck and the center of the equipment are used to clamp and push the workpiece stably to prepare for processing.

[0053] Finally, the position of the lower turret 50 is adjusted and the workpiece support sleeve 30 is supported by the rolling support seat 20 to achieve indirect support for the workpiece.

[0054] Specifically, place the rolling support seat 20 on the top end face of the support block 11, then adjust the lower turret 50 to move left and right along the X-axis and up and down 45°, and adjust the distance between the bearing 23 in the rolling support seat 20 and the workpiece support sleeve 30 until the bearing 23 is engaged in the annular groove 31 and contacts the workpiece support sleeve 30.

[0055] At this time, the equipment can be started, the workpiece drives the workpiece support sleeve 30 to rotate, and the tool clamped by the upper turret is used to perform turning and milling processing from one side of the workpiece. The support platform 10 supports the workpiece from the other side of the workpiece through the rolling support seat 20, which meets the processing requirements and avoids damage to the equipment. The structure is simple and the cost is low, which meets the actual processing needs.

[0056] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
