Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to an electromechanical integrated polishing machine. Background Technology

[0002] In the mass production of ring-shaped components (such as sealing rings, bearing rings, and gear rings), their inner and outer peripheral walls often require high-quality polishing in subsequent processes to meet technical specifications such as assembly accuracy, airtightness, or rotational stability. However, existing polishing equipment, especially automated polishing systems for ring-shaped workpieces with different diameters and wall thicknesses, still suffers from the following issues regarding structural compatibility and precision adjustment capabilities:

[0003] 1. Limited radial adaptation range of polishing components: Most equipment only supports unidirectional or limited spacing adjustment, which cannot flexibly adapt to the polishing needs of workpieces with different diameters. It is necessary to frequently change fixtures or adjust modules, which is cumbersome and affects the continuity of production.

[0004] 2. Lack of synchronous adjustment mechanism for inner and outer peripheral walls: Existing polishing mechanisms often fail to achieve bidirectional linkage adjustment of the spacing between the polishing columns of the inner and outer peripheral walls of the workpiece, which requires separate operation during the adjustment process, easily causing errors or asymmetrical adjustment, and reducing polishing accuracy.

[0005] Therefore, there is an urgent need for a mechatronics polishing equipment with wide adaptability and small adjustment synchronization error to improve the equipment's compatibility, control accuracy and operating efficiency in polishing operations of multi-specification circular workpieces.

[0035] Example 1

[0036] Reference Figure 1 and 2 The first embodiment of this utility model provides an electromechanical integrated polishing machine, comprising:

[0037] Main Module 100:

[0038] It includes an electric telescopic rod 101 and a rotary motor 102, wherein the rotary motor 102 is fixedly installed on the top of the polishing execution module 400, and its output shaft is coaxially connected to the fixed end of the electric telescopic rod 101, which is used to drive the electric telescopic rod to rotate vertically.

[0039] The movable end of the electric telescopic rod 101 is used for vertical telescopic movement, thereby driving the entire polishing execution module to move in the vertical direction to adapt to the processing needs of different heights or workstations.

[0040] Radial adjustment module 200:

[0041] The system includes a control box 201, which is fixedly connected to the movable end of the electric telescopic rod 101. The control box 201 contains a double-stroke mechanism 202, which includes a large lead screw 2021 located on the central axis and small lead screws 2022 symmetrically arranged on both sides thereon.

[0042] The large lead screw 2021 is driven by the adjusting motor 2023, which drives the relevant components of the entire small lead screw 2022 to move left and right, thereby adjusting the diameter of the outer ring workpiece. The small lead screw 2022 is driven by the motor 2024 to adjust the spacing between the inner and outer polishing pillars to match the workpiece thickness.

[0043] Spacing adjustment module 300:

[0044] It includes a large adjusting seat 301 and a small adjusting seat 302. The large adjusting seat 301 is connected to the large lead screw 2021 via a screw pair and can slide along the lead screw axis; the small adjusting seat 302 is mechanically connected to the small lead screw 2022 and achieves left and right adjustment of its position through rotation drive.

[0045] The small adjustment seat 302 is fixed to the large adjustment seat 301 by fasteners 303 (such as screws) to ensure consistent movement in the main direction while retaining the ability to make fine adjustments.

[0046] Polishing execution module 400:

[0047] Each small adjustment seat 302 is equipped with a set of inner polishing pillars 401 and outer polishing pillars 402. The polishing head contacts the inner and outer peripheral walls of the annular workpiece to achieve full-coverage polishing of the annular surface.

[0048] Example 2

[0049] Reference Figure 2 , 3 4 is the second embodiment of this utility model. The difference between this embodiment and the first embodiment is that this embodiment further introduces an anti-rotation structure optimization to improve the overall processing stability of the equipment.

[0050] Transmission anti-rotation structure:

[0051] A drive shaft 501 is arranged through the small adjusting seat 302. One end of the drive shaft 501 is connected to the motor 2024, and the small lead screw 2022 is installed outside the drive shaft 501 in a sleeve manner.

[0052] The drive shaft surface is provided with several anti-rotation ribs 5011, which are interlocked with the rib groove structure provided on the small lead screw 2022. Thus, during the drive rotation process, the small lead screw 2022 can rotate with the drive shaft and slide along the axial direction at the same time, achieving the dual purpose of position change and preventing idle rotation.

[0053] Example 3

[0054] Reference Figure 2 , 3 4 is the third embodiment of this utility model. This embodiment differs from the first embodiment in that it is further optimized based on the above embodiments, wherein the structure of the small lead screw 2022 is further optimized, as follows:

[0055] The mechatronics polishing machine is equipped with four sets of small lead screws 2022, which are located on both sides of the large lead screw 2021 and arranged in a rectangular array. Each set of small lead screws 2022 has two sections of external thread structure with opposite thread directions, namely one section of left-hand thread and one section of right-hand thread.

[0056] Each section of the external thread structure is connected to a set of small adjusting seats 302, so that the small adjusting seats 302 in both directions can move inward / outward simultaneously through the forward and reverse rotation of the lead screw, thereby further improving the adjustment efficiency and symmetry.

[0057] Example 4

[0058] Reference Figure 2 , 3 4 is the fourth embodiment of this utility model. This embodiment differs from the first embodiment in that, based on the above embodiments, the structure of the small adjusting seat 302 is further improved as follows:

[0059] Adjust the lugs and guide structure:

[0060] The small adjustment seat 302 is provided with adjustment lugs 3021 on both sides. The lugs 3021 are embedded in the preset slide grooves in the control box 201 by sliding connection.

[0061] The small adjustment seat 302 also includes a guide rod 3022, one end of which is fixed to the lug 3021, and the other end passes through the guide groove in the control box 201, so that the movement of the small adjustment seat has linear guidance and restriction, effectively preventing swaying or deviation.

[0062] The guide slide of the control box 201 is equipped with a visual scale display window 2011, which is used to display the moving distance and displacement status of the polishing column in real time, thereby improving the ease of operation and adjustment accuracy.

[0063] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0064] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
