Description

Technical Field

[0001] This invention relates to a processing device, specifically a processing device for mechanical parts. Background Technology

[0002] In the current field of mechanical parts processing, there are many pain points in the grinding of the outer diameter of tubular workpieces. Existing processing equipment mostly adopts a single-sided external clamping method, resulting in poor workpiece centering accuracy and easy circumferential movement during grinding, leading to uneven grinding patterns, excessive coaxiality, and high rework rates. Meanwhile, traditional grinding equipment often uses a single grinding head for fixed-point operation, requiring repeated manual adjustments to the workpiece position. This not only results in low efficiency but also makes it difficult to maintain consistent grinding intensity at different positions, easily leading to localized over-grinding or under-grinding. Furthermore, the large amount of metal dust generated during grinding is directly dispersed in the workshop, polluting the working environment and easily adhering to the still-cooled grinding surface of the workpiece, forming scratches and further reducing the yield of finished products. Existing equipment mostly requires multiple independent drive mechanisms to complete clamping, shifting, and grinding actions separately, resulting in a redundant and complex overall structure, high equipment maintenance costs, and difficulty in adapting to the high-precision processing requirements of small to medium batches of multi-specification tubular parts. Therefore, a processing device for mechanical parts needs to be designed to solve this problem. Summary of the Invention

The end of the intermittent horizontal rotation assembly away from the drive assembly is connected to one of the drive gears and the guide block respectively. A light is installed at the bottom of the horizontal plate.

[0006] As a further aspect of the present invention: the driving assembly includes a dual-axis motor mounted on a vertical plate. A first drive shaft and a second drive shaft are respectively mounted on the output end of the dual-axis motor. The first drive shaft is connected to an adjustment assembly, and the end of the second drive shaft away from the dual-axis motor is connected to an intermittent transverse rotation assembly. The adjustment assembly includes a driven shaft, one end of which is rotatably connected to the side wall of the adjustment groove, and the other end of which is connected to a threaded rod. The end of the threaded rod away from the driven shaft is rotatably connected to the side wall of the adjustment groove. The threaded rod is threadedly connected to an adjustment block. A connecting unit is mounted on the first drive shaft, and the end of the connecting unit away from the first drive shaft is connected to the driven shaft. The intermittent transverse rotation assembly includes an intermittent transverse mechanism and a rotation mechanism. The rotation mechanism includes a rotating rod. The rod is rotatably connected to the side wall of the mounting plate, and one end of the rotating rod is fixedly connected to a telescopic sleeve through the mounting plate. The end of the telescopic sleeve away from the rotating rod is fixedly connected to a power shaft. The end of the power shaft away from the telescopic sleeve passes through the side wall of the annular plate and extends into the annular cavity to connect with one of the drive gears.

[0008] Compared with the prior art, the beneficial effects of the present invention are: by using the combination clamping structure of inner support and outer clamp, the workpiece is clamped from multiple points inside the workpiece to the side of the mating end face, and automatic centering can be completed without additional manual alignment, completely eliminating the radial movement and circumferential slippage problems in the workpiece grinding process. The coaxiality accuracy of the workpiece clamping is improved by more than 40% compared with the traditional outer clamping method, and the grinding rework rate is greatly reduced.

[0009] Relying on a single dual-axis motor to synchronously drive clamping and feeding, intermittent station lateral movement and circumferential grinding action, multiple independent drive units are eliminated, the overall structure of the equipment is more compact, manufacturing costs and subsequent maintenance difficulty are significantly reduced, and the mode of synchronous circumferential operation of multiple grinding heads increases the grinding efficiency of a single workpiece by more than 2 times.

[0010] The dust extraction head moves synchronously with the grinding station, accurately capturing metal dust from dust-generating points. This not only prevents dust from spreading and polluting the workshop environment, but also eliminates secondary scratches caused by dust adhering to the grinding surface of the workpiece. Combined with the supplementary lighting structure in the work area, operators can observe the grinding status in real time, significantly improving the yield of finished products.

One end of the rotating rod 12 passes through the mounting plate 4 and is fixedly connected to a telescopic sleeve 19. The end of the telescopic sleeve 19 away from the rotating rod 12 is fixedly connected to a moving rod.

A driven gear 14 is mounted on the rotating shaft, and a sector gear 13 is mounted on the rotating rod 12. The sector gear 13 and the driven gear 14 intermittently mesh.

[0022] In this embodiment, during the material loading stage: the operator places the tubular mechanical parts to be processed on the upper station of the base 1, the dual-axis motor 8 starts rotating in the forward direction, the first drive shaft 10 outputs torque, and transmits the power to the driven shaft 30 through the connecting unit 32, which drives the threaded rods 31 in the adjusting grooves 45 on both sides to rotate synchronously in the same direction.

[0023] Coarse positioning stage: The threaded drive adjustment block 33 slides in a straight line towards each other along the adjustment groove 45, driving the vertical plate 7, crossbar and drive plate to move closer to the workpiece. At this time, the side clamping plate 35 first contacts the two end faces of the workpiece, completing the initial axial positioning of the workpiece.

[0024] Adaptive internal support stage: The vertical plate 7 continues to feed towards the workpiece, and the side clamping plate 35 stops axial movement due to the obstruction of the workpiece end face. It begins to compress the elastic component 34 along the crossbar towards the vertical plate 7. The axial reaction force generated by the elastic component 34 continues to act on the side clamping plate 35, forming a constant pre-clamping force on the workpiece end face.

[0025] Inner support locking stage: As the vertical plate 7 continues to advance, the inner plate 36 is fully inserted into the inner hole of the workpiece. The inner support rod 40, which is hinged to the inner plate 36, is deflected by the reverse support force of the inner hole wall and is pushed outward along the hinge point. This pushes the inner support block 39 to slide outward in a synchronous radial direction along the annular inner support groove 38 on the inner plate 36. Multiple inner support blocks 39 simultaneously press against the inner hole wall of the workpiece, forming an annular multi-point support from the inside, completely eliminating the radial gap of the workpiece, realizing the automatic centering of the workpiece, and avoiding circumferential movement during subsequent grinding.

[0026] Intermittent transverse movement station switching: The second drive shaft 9 transmits torque to the rotating rod 12 through the connecting mechanism 11, driving the sector gear 13 to rotate continuously for a full revolution. The teeth of the sector gear 13 only mesh with the driven gear 14 within a set angle range, and are disengaged at other times, so that the driven gear 14 drives the rotating rod 15 and the lead screw 16 to perform an intermittent "rotate-stop-rotate" motion, driving the guide block 17 to make precise step transverse movements along the guide groove at the bottom of the horizontal plate 3, and precisely stopping after moving a set distance, so that the annular plate 18 is precisely aligned with each section of the workpiece to be ground along the axial position.

[0027] Circumferential grinding: As the rotating rod 12 rotates, the torque is transmitted to the power shaft 20 through the telescopic sleeve 19. The telescopic sleeve 19 can automatically and adaptively extend and retract with the lateral displacement of the annular plate 18, ensuring uninterrupted power transmission. The power shaft 20 drives the drive gear 22 in the annular cavity 23 to rotate, meshing with the drive gear 21 to make a 360° full circumference along the inner wall of the annular cavity 23. The mounting rod 24 on the side wall of the annular gear 21 drives all the placement frames 25 to revolve synchronously, allowing multiple grinders 28 to make an annular circular motion around the outer circumference of the workpiece.

[0028] Radial grinding feed: The telescopic component 29 in the placement frame 25 extends gradually according to the preset program, pushing the placement block 26 to move towards the center of the workpiece along the guide groove of the placement frame 25, driving the grinder 28 to gradually adhere to and press against the surface of the workpiece. By controlling the extension amount of the telescopic component 29, the grinding pressure is precisely adjusted. With the circumferential rotation of the ring gear 21, the uniform grinding of the entire outer circle of the workpiece is completed in one go, avoiding the defect of excessive grinding in some areas.

[0029] Visual aids for operation: The lighting lamp 5 installed at the bottom of the horizontal plate 3 adopts an anti-glare industrial lighting design. The light is evenly projected from a 45° angle above to the grinding operation area, completely covering the processing space inside the ring plate 18, eliminating the visual shadow at the contact position between the grinder 28 and the workpiece. The operator can view the grinding pattern and wear status in real time through the observation window outside the equipment and adjust the processing parameters in a timely manner.

[0030] Furthermore, both the connecting unit 32 and the connecting mechanism 11 can be gear sets or pulley sets, etc., which will not be described in detail here.

[0031] Furthermore, the elastic component 34 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0032] Furthermore, the telescopic component 29 can be an electric telescopic rod or an electric push rod, etc., which will not be described in detail here.

[0033] Please see Figures 1-2 As an embodiment of the present invention, a vacuum cleaner 42 is installed on the base 1, a vacuum cleaner pipe 43 is installed on the vacuum cleaner 42, a vacuum head 44 is installed at the end of the vacuum cleaner pipe 43 away from the vacuum cleaner 42, an mounting rod 24 is installed at the bottom of the annular plate 18, and the vacuum head 44 is installed on the mounting rod 24.

[0034] In this embodiment, at the instant the grinding operation starts, the vacuum cleaner 42 simultaneously receives the linkage trigger signal from the main control system of the equipment and starts running, forming a stable negative pressure flow field of -800Pa to -1200Pa inside the suction pipe 43. The suction head 44 is fixed to the bottom of the annular plate 18 by the mounting rod 24, maintaining a rigid connection with the annular plate 18, and completely following the intermittent lateral movement of the annular plate 18 to make synchronous displacement, always remaining in a position directly below the grinder 28. During the grinding process, the high-speed flying metal shavings and dust are directly captured by the negative pressure flow field the instant they are generated, and enter the suction pipe 43 through the guide port of the suction head 44, and finally transported to the dust collection chamber inside the vacuum cleaner 42. After being intercepted by the filter element, clean air is discharged, completely avoiding the outward diffusion of metal dust, preventing scratches caused by dust adhering to the ground surface of the workpiece, and improving the workshop working environment.

[0035] The working principle of this invention is as follows: When the machining device for mechanical parts is running as a whole, the tubular workpiece to be processed is first placed on the support position of the base 1. The dual-axis motor 8 on the vertical plate 6 is started. The first drive shaft 10 drives the driven shaft 30 and the threaded rod 31 to rotate synchronously through the connecting unit 32, driving the adjusting blocks 33 in the adjusting grooves 45 on both sides to slide towards each other, and driving the movable clamping mechanism on the vertical plate 7 to feed towards the workpiece. The side clamping plate 35 first contacts the two end faces of the workpiece to complete the initial axial positioning. As the vertical plate 7 continues to advance, the side clamping plate 35 compresses the elastic component 34 in the opposite direction along the crossbar to form a constant end face clamping force. At the same time, the inner plate 36 extends into the inner hole of the workpiece, and the inner support rod 40 is deflected by the reaction force of the inner wall, pushing the inner support block 39 to radially outward along the annular inner support groove 38 to clamp the inner hole of the workpiece, thus completing the automatic centering and anti-rotation clamping of the workpiece.

[0036] After clamping, the second drive shaft 9 drives the rotating rod 12 to rotate through the connecting mechanism 11. On one hand, the power is transmitted to the annular cavity 23 of the annular plate 18 through the telescopic sleeve 19 and the power shaft 20. The drive gear 22 meshes and drives the annular gear 21 to rotate around the entire circumference, driving the grinder 28 to move around the workpiece. The telescopic component 29 in the placement frame 25 pushes the grinder 28 to feed radially, completing uniform grinding around the entire circumference. On the other hand, the sector gear 13 on the rotating rod 12 intermittently meshes with the driven gear 14, driving the lead screw 16 to drive the guide block 17 to move laterally along the guide groove, allowing the annular plate 18 to accurately stop at different axial positions on the workpiece, completing the full-length grinding operation. The lighting lamp 5 at the bottom of the horizontal plate 3 provides supplementary lighting to the processing area throughout the process. The vacuum cleaner 42 on the base 1 starts synchronously, and the vacuum head 44 moves with the annular plate 18 to align with the dust generation point, instantly sucking in and collecting the metal dust generated during grinding, realizing closed-loop automated operation of the entire process of clamping, grinding, and dust removal.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
