Description
Technical Field
[0001] This utility model relates to polishing machines, and in particular to a polishing wheel movement and connection structure for a polishing machine. Background Technology
[0002] The current surface treatment of metal products mainly involves chemical polishing slurry in conjunction with abrasive polishing wheels for abrasive polishing. Most metal products are made of iron, copper, or aluminum alloys. The chemical polishing slurry used is relatively weakly corrosive, and the slurry residue left on the abrasive polishing wheel does not easily solidify or crystallize, making it easy to clean without affecting the next round of abrasive polishing.
[0003] Currently, the materials used for polishing are mainly high-strength titanium alloys, and the chemical polishing agents used are more corrosive and have the characteristic of easily volatilizing, solidifying, and crystallizing. Therefore, after prolonged sand polishing, the chemical polishing agents remaining on the surface of the sand polishing wheel tend to solidify and crystallize due to volatilization, affecting the accuracy of subsequent polishing. Thus, sand polishing wheels need to be replaced and cleaned after a certain period of use. However, existing polishing machines use manual replacement of sand polishing wheels, which not only consumes time and affects the efficiency of sand polishing, but also cannot be integrated with a sand polishing wheel cleaning mechanism to form a continuous replacement and cleaning process.
[0004] Therefore, there is a current need to design equipment that can automatically change abrasive polishing wheels, and that allows for multi-axis movement of the polishing wheels and metal products within an enclosed space for abrasive polishing operations, making it easier to centrally collect and recycle chemical polishing agents. To ensure a smooth automated abrasive polishing process, automated replacement of the polishing wheels, along with cleaning, is crucial and represents the main issue requiring improvement.
[0005] Therefore, how to improve the above-mentioned problems is the primary issue that this utility model aims to solve. Utility Model Content

[0061] Please see Figures 1 to 3 This is a preferred embodiment of the sand polishing wheel movement and connection structure of the sand polishing machine provided by this utility model, which mainly includes a wheel changing mechanism 1, a wheel picking mechanism 2, and a sand polishing wheel spindle mechanism 3, wherein:
[0062] like Figure 1 As shown, the wheel changing mechanism 1 has a wheel changing arm 11 and two opposing grippers 12. The opposing ends of the two grippers 12 are respectively provided with a gripping opening 13 for clamping the sand polishing wheel. The wheel changing arm 11 is driven by power and can move up and down along the Z-axis between a wheel pick-up / placement position P1 and a wheel changing position P2 to transport the sand polishing wheel.
[0063] The wheel-changing arm 11 is mounted on a sliding plate 14, and both ends of the sliding plate 14 are movably sleeved on guide rods 15 arranged along the Z-axis. The sliding plate 14 is driven to move up and down along the guide rods 15 via at least one telescopic rod 4. In this embodiment, the two telescopic rods 4 are symmetrically arranged on the left and right sides of the sliding plate 14 to apply a uniform thrust to the sliding plate 14, thereby smoothly transporting the polishing wheel.
[0064] Please refer to the following: Figure 2 As shown, the wheel-retrieving mechanism 2 has a wheel-retrieving arm 21. The wheel-retrieving arm 21 is driven by power to move along the Y-axis between a sand polishing wheel magazine 5 and the wheel-retrieving position P1, and moves along the X-axis between the two grippers 12. The wheel-retrieving arm 21 can rotate to be opposite one of the grippers 12, so as to move the sand polishing wheel from the sand polishing wheel magazine 5 into the gripper 12 of the wheel-changing arm 11, or to take the sand polishing wheel out from the gripper 12 and put it into the sand polishing wheel magazine 5.
[0065] In detail, the wheel-retrieving arm 21 is mounted on a lifting seat 22, which can be driven to move up and down along the Z-axis, driving the wheel-retrieving arm 21 to retrieve and place sand polishing wheels from the sand polishing wheel magazine 5. The lifting seat 22 can be driven to move up and down by a slide rail drive mechanism, a screw mechanism, a pneumatic cylinder, a hydraulic cylinder, etc., and is not limited in this utility model.
[0066] The lifting seat 22 is mounted on a transverse sliding seat 23, which can be driven to move laterally along the X-axis. In this embodiment, the transverse sliding seat 23 is slidably mounted on a transverse driving platform 24 and is driven to move laterally along the X-axis, so that the wheel picking arm 21 moves between the two grippers 12 to exchange the polishing wheel.
[0067] The transverse sliding seat 23 is mounted on a longitudinal sliding seat 25, which can be driven to move longitudinally along the Y-axis, allowing the wheel-picking arm 21 to move along the Y-axis between the sand polishing wheel magazine 5 and the wheel-picking position P1. The longitudinal sliding seat 25 is slidably mounted on two parallel Y-axis slide rails 26 and is driven by power to move along these rails, thereby allowing the wheel-picking arm 21 to move and change position along the Y-axis. The power source driving the longitudinal sliding seat 25 can be a pneumatic cylinder, a hydraulic cylinder, etc., and is not limited to any particular type in this invention.
[0068] It should be noted that, for example Figure 3 As shown, the distance between the two jaws 12 of the wheel-changing arm 11 is greater than the maximum shaft length of the wheel-taking arm 21, leaving enough space for the wheel-taking arm 21 to rotate to face the jaws 12 on different sides in order to complete the replacement of the sand polishing wheel.
[0069] Please see Figure 1 As shown, the sand polishing wheel spindle mechanism 3 is located below the wheel-removing mechanism 2, including a base 32 mounted on a slide rail mechanism 33, and a spindle head 31 assembled on the base 32. The base 32 is driven by a drive motor (not shown) to move along the X-axis on the slide rail mechanism 33, so as to drive the spindle head 31 to interact with the wheel-changing arm 11, which has moved to the wheel-changing position P2, to remove or install the sand polishing wheel. In detail, the spindle head 31 moves to one of the grippers 12 and presses the old sand polishing wheel 57 into the gripper 12 to remove the old sand polishing wheel 57; then it moves to the other gripper 12 to engage with the new sand polishing wheel 56 and then returns to its original position, thus completing the removal and installation of the sand polishing wheel.
[0070] In addition, such as Figure 3 The sand polishing wheel magazine 5 shown is preferably located between the wheel picking mechanism 2 and the sand polishing wheel spindle mechanism 3. It includes a transmission platform 51 and a plurality of carriers 52 mounted thereon. Each carrier 52 is mounted on a guide rail 53 and is driven by a track mechanism 54 to move along the guide rail 53. It can enter a cleaning area 55 on the transmission platform 51 for cleaning, so as to clean the sand polishing wheel being replaced in real time and prevent the chemical sand polishing liquid from solidifying and crystallizing.
[0071] The present invention, composed of the above-mentioned components, in practical applications, such as... Figure 4 and Figure 5 As shown, the wheel-retrieving arm 21 is driven by a power source to move along the Y-axis to the sand polishing wheel magazine 5, and then moves along the X-axis to above one of the carriers 52. The lifting seat 22 drives the wheel-retrieving arm 21 to move down along the Z-axis, so that the sand polishing wheel on the carrier 52 is engaged with the wheel-retrieving arm 21 and then moves up to reset, completing the sand polishing wheel retrieval action.
[0072] like Figure 6 and Figure 7As shown, at this time, the wheel-changing arm 11 is in the wheel-picking position P2, and the wheel-picking arm 21 moves along the Y-axis to between the two jaws 12 of the wheel-changing arm 11. The wheel-picking arm 21 rotates to be opposite one of the jaws 12, and then moves along the X-axis to clamp the sand polishing wheel into the jaw 12 and then retracts, completing the sand polishing wheel exchange and transfer action.
[0073] Next, as Figure 8 and Figure 9 As shown, the base 32 drives the spindle head 31 to move along the X-axis, positioning it opposite the wheel-changing position P2. The wheel-changing arm 11, driven by power, moves along the Z-axis from the wheel-picking / placing position P1 to the wheel-changing position P2, at which point the spindle head 31 is positioned between the two grippers 12 of the wheel-changing arm 11. Figure 10 As shown, the base 32 drives the spindle head 31 to move toward the empty gripper 12, and after the old sand polishing wheel 57 on the spindle head 31 is inserted into the gripper 12, then... Figure 11 The jaws 12, which are shown moving to hold the new polishing wheel 56, are then reset after mounting the polishing wheel onto the spindle head 31. Figure 12 As shown, this completes the exchange of the old and new polishing wheels.
[0074] The wheel-changing arm 11 moves upward along the Z-axis to the wheel-picking / retrieving position P1. The wheel-picking arm 21 then moves along the Y-axis between the two grippers 12 of the wheel-changing arm 11, rotates to face the grippers 12 holding the old sand polishing wheel, and moves along the X-axis to pick up the old sand polishing wheel. It then moves along the X-axis to separate the old sand polishing wheel from the grippers 12, thus completing the removal of the old sand polishing wheel. It then moves along the Y-axis to above the sand polishing wheel magazine 5, rotates to face the carrier 52, and moves downward along the Z-axis to return the old sand polishing wheel to the carrier 52. The track mechanism 54 then drives the carrier 52 to move to the cleaning area 55 for cleaning, thus completing one wheel-changing procedure.
[0075] In summary, the sand polishing wheel movement and connection structure of the sand polishing machine provided by this utility model can achieve the following improvements:
[0076] First, it improves the efficiency of sand polishing wheel replacement. This utility model uses a wheel-picking mechanism to take out a new sand polishing wheel from the sand polishing wheel storage, a wheel-changing mechanism to transport the sand polishing wheel, and a sand polishing wheel spindle mechanism to complete the sand polishing wheel replacement. Then, the wheel-changing mechanism sends the old sand polishing wheel back and the wheel-picking mechanism takes it out and returns it to the sand polishing wheel storage. This automated replacement and transportation of sand polishing wheels replaces the manual replacement method, thus improving the efficiency of the replacement operation.
[0077] Secondly, it facilitates the establishment of an automated process for replacing and cleaning sand polishing wheels. This invention can be connected with a sand polishing wheel cleaning mechanism to achieve automated replacement and cleaning of sand polishing wheels, solving the problem of polishing liquid solidifying and crystallizing on the surface of sand polishing wheels, and extending the service life of sand polishing wheels.
[0078] The above embodiments are disclosed only to illustrate the present utility model and are not intended to limit the present utility model. Any substitution of equivalent components should still fall within the scope of the present utility model.
[0079] In summary, this invention enables those skilled in the art to understand that it can indeed achieve the aforementioned objectives, and thus complies with the provisions of the Patent Law, and is therefore submitted for application in accordance with the law.
