Description

Field of the invention

[0001] The present invention relates to an automatic deburring device, and more particularly, to a device for deburring in three-dimensional X, Y, and Z space. It allows for increased shaft spacing to accommodate larger elastomers and fully automates the entire deburring process. The invention not only saves labor but also effectively improves processing efficiency. State of the art

[0002] O-ring seals are typically made of synthetic rubber and are long-lasting and suitable for sealing. However, burrs are created during the manufacturing process of O-ring seals, which must be removed through post-processing to ensure that the sealing performance of the O-ring seals is not compromised when installed in the machine.

[0003] Previous manual deburring processes are time-consuming and labor-intensive, resulting in high costs and not being economically viable. Furthermore, deburring is largely performed manually and lacks automation, resulting in an inability to increase production line output. As demand increases, this processing method can no longer meet consumer needs, which is detrimental to both manufacturers and consumers. Furthermore, manual deburring results in inconsistent quality of O-ring seals and a higher defect rate, which in turn increases production costs. Furthermore, the sharp cutting tools of deburring machines are quite dangerous, requiring operators to exercise extreme caution to avoid work-related accidents.

[0004] Therefore, processes have increasingly shifted toward the use of chill-hardening treatments. Such deburring devices typically use expensive liquid nitrogen as a coolant, which not only results in high processing costs, which are economically disadvantageous, but also causes the O-ring seals to harden excessively and become brittle due to nitrogen cooling. While the burrs can be removed after collisions, they also compromise the original elasticity of the synthetic rubber O-ring seals, making them susceptible to deterioration and cracking due to cooling and hardening.

[0005] Conventional manual deburring of O-ring seals is no longer satisfactory in modern society due to labor shortages and rising wages. The subsequently developed deburring devices also suffer from the problems of high nitrogen costs and over-hardening, resulting in a deterioration of the quality of the O-ring seals. The present invention was developed to solve the above-mentioned problems and technical deficiencies of conventional deburring. Object of the invention

[0022] The three-dimensional movable mechanism 2 is arranged on the support platform 11 of the machine cabinet 1 and can selectively perform three-dimensional movements. The three-dimensional movable mechanism 2 comprises two first axial guide rails 21, 22, a second axial guide rail 23, and a third axial guide rail 24. The two first axial guide rails 21, 22 are divided into a first axial guide rail of the high segment 21 and a first axial guide rail of the low segment 22.

The first axial guide rail of the low segment 22 is arranged on the second axial guide rail 23 and is movable forward and backward along the Y-axis direction defined by the second axial guide rail 23.A first movable block 221 and a fixed block 222 are arranged at each of the two ends of the first axial guide rail of the low segment 22, the first movable block 221 being movable to the left and right along the X-axis direction defined by the first axial guide rail of the low segment 22, the third axial guide rail 24 being arranged on the first axial guide rail of the high segment 21 and being movable to the left and right along the X-axis direction defined by the first axial guide rail of the high segment 21, and a second movable block 241 being arranged on the third axial guide rail 24 and being movable up and down along the Z-axis direction defined by the third axial guide rail 24.

[0023] The mounting mechanism 3 is arranged on the first axial guide rail of the low segment 22 and includes a speed-adjustable motor 31 and two mounting shafts 32.

[0025] The microscopic unit 5 is located above the knife steering unit 4 and outputs real-time information about the deburring work on the surface of the elastomer 9 to be deburred. This real-time information includes the status of the burr processing or information about possible malfunctions in the device.

[0026] The automated arm 6 is arranged on the machine cabinet 1 and serves to place the elastomer 9 to be deburred onto the two mounting shafts 32 and to clamp the finished deburred elastomer by means of the mounting shafts 32.

[0032] In a preferred embodiment of the present invention, the automatic deburring device 100 further comprises a tension tester (not shown) electrically connected to the mounting mechanism 3 to ensure that the tension of an elastomer 9 to be deburred is neither too high nor too low before deburring.

[0033] In a preferred embodiment of the present invention, the automatic deburring device 100 further comprises a burr collecting plate (not shown) which is arranged on the support platform 11 and serves to collect the chips falling off during the deburring work of the elastomer 9 to be deburred.

After the deburring work is started by the human-machine interface 81, the two mounting shafts 32 are moved in the X-axis direction to stretch the elastomer 9 to be deburred to a tight fit. Then, the mounting mechanism 3 is driven by the first axial guide rail of the low segment 22 to move on the second axial guide rail 23 along the Y-axis direction toward the knife steering unit 4. By the second movable block 241, the knife steering unit 4 is moved on the third axial guide rail 24 along the Z-axis direction toward the elastomer 9 to be deburred.The cutting blade 43 is driven by the steering motor 41 to rotate clockwise and counterclockwise to achieve the correct angle for deburring. With the automatic deburring device 100 according to the invention, both the inner ring and the outer ring of an elastomer 9 to be deburred can be deburred. For example, if the cutting blade 43 is moved in the Z-axis direction toward the top of the elastomer 9 to be deburred, the outer ring of the elastomer 9 to be deburred can be deburred. If the cutting blade 43 is moved in the Z-axis direction toward the inner ring of the elastomer 9, the inner ring of the elastomer 9 to be deburred can be deburred.

[0037] As can be seen from the above, in the automatic deburring device according to the invention, an elastomer to be deburred is automatically placed on the mounting mechanism. Through the cooperation of the three-dimensional movable mechanism and the knife steering unit, the elastomer to be deburred is automatically fixed to perform bidirectional deburring processing on the inner and outer rings. After completion, the finished product is automatically released and removed. In this way, deburring processing in the three-dimensional X, Y, and Z space can be realized, allowing the shaft pitch to be increased to accommodate a larger elastomer and fully automating the entire deburring process. With this invention, not only can labor savings but also effectively improve processing efficiency.

[0038] In summary, the automatic deburring device according to the invention effectively eliminates the deficiencies of the prior art, enabling deburring in three-dimensional X, Y, and Z space, increasing the shaft spacing to accommodate larger elastomers, and fully automating the entire deburring process. The invention not only saves labor but also effectively improves processing efficiency. The invention is more advanced, more practical, and more user-friendly, thus meeting the requirements for a utility model application. The application is filed in accordance with the law.
