Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a cam-type loading automatic straightening machine. Background Technology

[0002] During the machining or heat treatment of cylindrical parts, bending deformation is inevitable due to external forces or thermal stress. This bending deformation must be corrected to avoid affecting subsequent precision machining of these shaft-like workpieces. Currently, the existing technology for straightening cylindrical parts typically involves placing the cylindrical parts with uniform outer diameters within the spindle clamp and extending them 30 mm beyond the clamp. The part is rotated, and the runout value is measured by measuring devices on both sides. Then, based on software calculations, a certain force is applied vertically by a servo electric cylinder to achieve the required runout. After straightening at that point, the part is automatically withdrawn a certain distance, and the above actions are repeated until the entire part is straightened. However, because the above method straightens the part in segments, each segment requires repeated clamping, which compromises accuracy. Therefore, to address these issues, we propose a novel cam-type loading automatic straightening machine. Utility Model Content

[0022] The beneficial effects of this utility model are:

[0023] (1) This utility model proposes a cam-type automatic straightening machine. The cam is driven to rotate by a servo motor. When rotating, the diameter of the cam arc increases slowly, pushing the pressure head to swing down. The linear motion of the cam disperses a pulse signal into several points, which significantly improves the pressure head pressing accuracy compared with linear pressing. Combined with the parallel laser measurement sensor to scan the parts and the drive motor to drive and adjust the parts, the parts can be fully scanned and straightened in one clamping.

[0024] (2) This utility model proposes a cam-type automatic straightening machine, which uses a floating support frame driven by a drive motor to support the parts. During the entire straightening process, the floating support frame can move with the change of the area to be straightened of the parts, thereby supporting the parts and preventing the parts from deforming during the straightening process.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Example:

[0033] This embodiment describes the structure of a cam-type loading automatic straightening machine.

[0034] like Figure 1-4 As shown, a cam-type loading automatic straightening machine includes: a pressure head assembly 1, wherein the pressure head assembly 1 is integrally formed;

[0035] The pressure head assembly 1 is mounted on the base 21 via a fixing seat 10;

[0036] Furthermore, the fixed base 10 is movably connected to the pressure head assembly 1 via a fixed pin 9, and the fixed base 10 is mounted on the base 21 via M12 bolts;

[0037] The pressure head assembly 1 is mounted on a synchronous belt 7 and a pressure head 3 via a linear guide rail 2 at its lower part.

[0038] Furthermore, the two ends of the synchronous belt 7 are respectively mounted on the mounting part 23 by M8 bolts 4.

[0039] Furthermore, a servo motor 5 is provided on one end of the mounting part 23, and a synchronous belt mount 6 is provided on the other end of the mounting part 23, the synchronous belt mount 6 being connected to the synchronous belt 7.

[0040] A cam 12 driven by a servo motor 13 is provided below the base 1;

[0041] A connecting plate 22 is fixed below one side of the pressure head assembly 1. A guide wheel 11 is installed at the lower end of the connecting plate 22, and the guide wheel 11 contacts the cam 12.

[0042] The base 21 is equipped with a parallel laser measurement sensor 20 and a servo motor 5 that drives the movement of the drive component 15.

[0043] Furthermore, the servo motor 16 is mounted on the mounting base 24. The servo motor 16 is used to drive the rotation of the drive part, so that the parallel laser measurement sensor can completely scan all the straightening points of the part. The part 15 is clamped in the pneumatic chuck 14, which is mounted on the mounting base 24.

[0044] Furthermore, a fixing block 19 is provided on the base 21, and a floating support frame 18 driven by a drive motor is provided on the fixing block 19. A sliding groove is opened on the inner side of the floating support frame 18, and the sliding groove slides along the fixing block 19.

[0045] In this embodiment, the floating support frame 18 is provided with a placement groove for supporting the part 15.

[0046] During the straightening process, the floating support frame 18 moves in the same direction as the part 15.

[0047] In this embodiment, the floating support is used to support the part, and during the straightening process, under the action of the drive motor, the floating support can move as the area of ​​the part that needs to be straightened changes, so as to achieve the best support force for the part and prevent the part from deforming during the straightening process.

[0048] Furthermore, the parallel laser measurement sensor 20 is fixedly mounted on the base 19 and located on both sides of the part 15.

[0049] In this embodiment, during the straightening process, the scanning direction of the parallel laser measurement sensor 20 is perpendicular to the part 15.

[0050] The straightening machine is controlled by a central control console, and its operation is achieved through a program. The central control console is common knowledge, and the other equipment and drive devices used in conjunction with the straightening machine are also well-known to those skilled in the art, and therefore will not be described in detail here. When part 5 is placed in the pneumatic chuck 14, the program is started. Part 15 is pushed into the parallel laser measurement sensor 20 by the drive motor to begin scanning and measurement analysis. Based on the measurement results, servo motor 15 drives the pressure head 3 to move to the position on the part that needs straightening. Servo motor 213 drives the cam 12 to rotate. Due to the cam's structural characteristics, its outer diameter continuously increases during rotation. The cam 12 pushes the guide wheel 11, causing the pressure head assembly 1 to perform a knocking motion downwards. With the cooperation of the floating support frame 18, the straightening work of one straightening point is completed. Without changing the servo motor's operating conditions, the depth of each downward pressure frequency can be reduced to improve straightening accuracy. This straightening machine can achieve straightening of all points on the part to be straightened in a single clamping operation, driven by the motor. Meanwhile, after straightening is completed, the pressure head returns to its original position, freeing up the area above the parts and providing space for the automatic loading and unloading gantry to assist in processing, which greatly increases efficiency and production capacity.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
