Description

Technical Field

[0001] This invention relates to the field of automated machining technology, and in particular to a method for machining mechanical parts. Background Technology

[0002] Mechanical processing automation refers to an advanced manufacturing technology that utilizes automation technology to enable processing equipment to automatically complete processing tasks and reduce human intervention during the mechanical processing process.

[0003] On a machine tool, a probe can measure the reference surface of the workpiece, compare the measurement data with the theoretical design data, and then automatically adjust the position of the workpiece to precisely align it with the machining coordinate system, thereby ensuring machining accuracy.

[0004] In existing technologies, probes can only identify the surface of a part and cannot identify the plane where the machining lines are located, thus failing to identify the cross-sections inside the part that need to be cut or machined. During the machining process, technicians need to measure and adjust the position and orientation of the part, which is cumbersome and causes interruptions in automated machining. Furthermore, manual adjustments introduce measurement errors, affecting the machining accuracy of the part. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a machining method for mechanical parts to solve the technical problem in the prior art that the probe cannot identify the plane where the machining line is located.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] A method for machining mechanical parts, employing a machining line identifier, includes the following steps:

[0008] S1: Draw horizontal machining lines on the part;

[0009] S2: Clamping parts;

[0010] S3: Use a processing line identifier to convert the processing line;

[0011] S4: Place the processing table on the machine tool;

[0012] S5: The probe identifies the position of the part and performs automatic processing.

[0013] Furthermore, in step S1, the cross section of the part that needs to be processed is determined according to the processing requirements, and the horizontal machining line is drawn on the part using a measuring tool.

[0014] Furthermore, in step S2, the machining table includes a fixture. The part with the horizontal machining line drawn is placed on the machining table and clamped by the fixture so that the horizontal machining line is parallel to the machining table.

[0015] Furthermore, the processing line identifier includes an identification unit, a limiting unit, a lifting unit, and a fixed housing. The lifting unit is housed within the fixed housing and is connected to the identification unit. The limiting unit is connected to the fixed housing and is used to restrict the position of the identification unit.

[0016] Further, step S3 includes the following steps:

[0017] S31: Install a processing line identifier;

[0018] S32: Horizontal adjustment recognition unit.

[0019] Furthermore, in step S31, the fixed box is fixed on the processing table so that the pointed end of the identification unit points in the direction of the horizontal processing line.

[0020] Further, in step S32, the identification unit includes an identification tip, a lifting platform, and a limiting piece. The identification tip is disposed on the lifting platform, and the limiting piece covers the identification tip and is connected to the limiting unit. The limiting piece is used to restrict the position of the identification tip so that the identification tip can move horizontally along the lifting platform.

[0021] Furthermore, in step S32, the identification tip is moved along the lifting platform to bring it closer to the part.

[0022] Furthermore, step S3 also includes the following steps:

[0023] S33: Height of the coarse-adjustment recognition unit;

[0024] S34: Fine-tune the height of the recognition unit.

[0025] Furthermore, in step S4, the machining table is placed on the machine tool so that the machine tool and the part are positioned together, thereby enabling the machine tool to process the part.

[0026] Furthermore, the lifting unit includes a rotary rod, a gear ring, a drive gear, a lifting rack, a gear ring connecting rod, and a coarse adjustment gear. The lifting rack is connected to the lifting platform, the gear ring is connected to the fixed housing through the gear ring connecting rod, the gear ring connecting rod is connected to the fixed housing through a bearing seat, the outer ring of the gear ring meshes with the lifting rack, the inner ring of the gear ring meshes with the drive gear, and the rotary rod passes through the fixed housing and is connected to the drive gear.

[0027] Furthermore, the coarse adjustment gear is located inside the gear ring and meshes with the gear ring. When the drive gear drives the gear ring to rotate, the coarse adjustment gear does not contact the drive gear.

[0028] Furthermore, the gear ring connecting rod is provided with a moving groove and a connecting hole. The connecting hole is located in the moving groove, and the drive gear is provided with a connecting end. The connecting end can move along the moving groove and be inserted into the connecting hole.

[0029] Furthermore, a bearing sleeve is installed inside the connecting hole, and the connecting end is connected to the connecting hole through the bearing sleeve. The position of the connecting hole matches the position of the gear ring and the coarse adjustment gear. When the connecting end is inserted into the connecting hole, the drive gear can mesh with the coarse adjustment gear or the inner ring of the gear ring.

[0030] Furthermore, a sliding groove is provided on the fixed box body, and the rotating rod can move in the sliding groove. When the rotating rod moves in the sliding groove, it can drive the connecting end to move in the moving groove.

[0031] Further, in step S33, the rotary rod is moved in the slide groove so that the connecting end moves in the moving groove until the drive gear meshes with the coarse adjustment gear. The rotary rod is pressed towards the fixed housing so that the connecting end enters the connecting hole. The rotary rod is rotated so that the drive gear drives the coarse adjustment gear to rotate, which in turn drives the gear ring to rotate, so that the lifting rack moves to a position close to the processing line, thus completing the coarse adjustment of the identification unit.

[0032] Further, in step S34, the rotary rod is moved away from the fixed housing so that the connecting end moves out of the connecting hole. The rotary rod is moved along the slide groove until the drive gear meshes with the gear ring. The rotary rod is pressed towards the fixed housing so that it enters the connecting hole. The rotary rod is rotated so that the drive gear drives the gear ring to rotate, thereby moving the lifting rack until the identification tip contacts the processing line, completing the fine adjustment of the identification unit.

[0033] Furthermore, step S3 also includes:

[0034] S35: Fixed identification unit;

[0035] S36: The cross section where the processing line is located;

[0036] S37: Adjust the identification tip away from the part.

[0037] Furthermore, in step S35, the limiting unit includes a limiting platform and bolts. The limiting platform is set on both sides of the lifting platform, and the bolts pass through the limiting platform. By adjusting the bolts, the bolts can be pressed against the lifting platform to fix the position of the lifting platform.

[0038] Furthermore, in step S36, the recognition unit also includes a recognition platform, which is connected to the recognition tip. A conversion plane is set on the recognition platform, and the conversion plane and the tip of the recognition tip are coplanar in the horizontal direction.

[0039] Furthermore, in step S37, the identification unit also includes a screw to move the identification tip along the lifting platform, so that the identification tip is away from the part. A threaded hole is provided on the identification tip, and the screw passes through the limiting piece and connects to the threaded hole to fix the position of the identification tip.

[0040] Furthermore, in step S5, the position information of the conversion plane is identified using the probe of the machining tool, and the part is automatically processed by the machining tool according to the position information identified by the probe.

[0041] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0042] (1) The machining method for mechanical parts provided by the present invention uses a machining line identifier to transform the plane on the part into a plane so that the probe can identify and collect the information. The position information of the transformed plane is identified by the probe of the machining tool, thereby realizing the collection of the position information of the plane on which the machining line is located. This enables the machining tool to automatically process the plane on which the machining line is located without the need for manual adjustment of the part's posture and position, and without causing interruption in the machining process. This enables the parts to be automatically processed, saving human resources and reducing machining errors caused by manual measurement. The operation is simple, saving machining time and improving the efficiency and accuracy of part processing.

[0043] (2) The machining method for mechanical parts provided by the present invention can collect and convert the position information of the machining line on the part through step S3, collect the machining line through the identification unit, and adjust the identification unit through steps S32, S33 and S34 so that the identification tip 11 contacts the machining line to realize the acquisition of the machining line. By setting a conversion plane that is coplanar with the tip of the identification tip in the horizontal direction, the plane where the machining line cannot be collected by the probe is represented, so that the position information of the conversion plane can be collected by the probe to realize the automated machining of the plane where the machining line is located. The structure is simple, and the accuracy of the identification unit in collecting machining line information is improved by coarse and fine adjustment of the identification unit.

[0044] (3) The machining method for mechanical parts provided by the present invention can fix the identification tip by setting a limiting piece, so that the identification tip can move horizontally along the lifting platform. The position of the identification tip can be fixed by screws and threaded holes, so that the position of the conversion plane is fixed, which is convenient for the probe to collect data. The identification tip can move horizontally along the lifting platform, so that it is convenient to move the identification tip closer to the part, improving the accuracy of the identification data collection on the machining line. After the data collection is completed, the identification tip can be moved away from the part to avoid interfering with the machining of the part. The limiting unit can fix the position of the lifting platform, so that the identification unit remains fixed after the lifting platform has completed coarse and fine adjustment, which is convenient for the probe to identify the conversion plane, improves the stability of the structure and the accuracy of the probe to collect the position information of the conversion plane.

Detailed Implementation

[0056] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the invention to illustrate the principles of the invention.

[0057] This invention provides a method for machining mechanical parts, employing a machining line identifier, such as... Figure 1 As shown, it includes the following steps:

[0058] S1: Draw a horizontal machining line on part 6;

[0059] S2: Clamp part 6;

[0060] S3: Use a processing line identifier to convert the processing line;

[0061] S4: Place the machining table 5 on the machining machine tool;

[0062] S5: The probe identifies the position of part 6 and performs automatic processing.

[0063] In step S1, specifically, the cross section of part 6 that needs to be processed is determined according to the processing requirements, and the horizontal processing line is drawn on part 6 using a measuring tool.

[0064] In step S2, specifically, the part 6 with the horizontal machining lines drawn is placed on the machining table 5, as follows: Figure 2 As shown, the machining table 5 includes a fixture 51, which is used to clamp the part so that the horizontal machining line is parallel to the machining table 5.

[0065] Furthermore, step S3 specifically includes:

[0066] S31: Install the processing line identifier.

[0067] Specifically, the fixed housing 4 is fixed on the processing table 5 so that the pointed end of the identification unit 1 points in the direction of the horizontal processing line.

[0068] like Figure 2 As shown, the processing line identifier includes an identification unit 1, a limiting unit 2, a lifting unit 3, and a fixed housing 4. The lifting unit 3 is installed inside the fixed housing 4 and is connected to the identification unit 1 to adjust the height of the identification unit 1. The limiting unit 2 is connected to the fixed housing 4 and is used to fix the position of the identification unit 1.

[0069] S32: Horizontal adjustment recognition unit 1.

[0070] Specifically, the identification tip 11 is moved along the lifting platform 13 to bring the identification tip 11 closer to the part 6.

[0071] like Figures 2-3As shown, the identification unit 1 includes an identification tip 11, a lifting platform 13, and a limiting piece 14. The identification tip 11 is disposed on the lifting platform 13. The limiting piece 14 covers the identification tip 11 and is connected to the limiting unit 2. The limiting piece 14 cooperates with the lifting platform 13 to limit the position of the identification tip 11, so that the identification tip 11 can move horizontally along the lifting platform 13.

[0072] S33: Height of coarse adjustment recognition unit 1.

[0073] Specifically, the rotating rod 31 is moved within the slide groove 41, causing the connecting end 331 to move within the moving groove 351 until the drive gear 33 meshes with the coarse adjustment gear 36. The rotating rod 31 is then pressed towards the fixed housing 4, causing the connecting end 331 to enter the connecting hole 352. The rotating rod 31 is then rotated, causing the drive gear 33 to drive the coarse adjustment gear 36 to rotate, which in turn drives the gear ring 32 to rotate, causing the lifting rack 34 to move to a position close to the processing line, thus completing the coarse adjustment of the identification unit 1.

[0074] like Figures 4-5 As shown, the lifting unit 3 includes a rotary rod 31, a gear ring 32, a drive gear 33, a lifting rack 34, a gear ring connecting rod 35, and a coarse adjustment gear 36. The lifting rack 34 is connected to the lifting platform 13. The gear ring 32 is fixed in the fixed housing 4 through the gear ring connecting rod 35. The gear ring connecting rod 35 is connected to the fixed housing 4 through a bearing seat. The outer ring of the gear ring 32 meshes with the lifting rack 34, and the inner ring of the gear ring 32 meshes with the drive gear 33. The rotary rod 31 passes through the fixed housing 4 and is connected to the drive gear 33. Rotating the rotary rod 31 can make the drive gear 33 rotate, thereby driving the gear ring 32 to rotate, thus driving the lifting rack 34 to move up and down, adjusting the height of the identification unit 1 so that the height of the identification tip 11 is consistent with the position of the processing line.

[0075] The coarse adjustment gear 36 is disposed inside the gear ring 32 and meshes with the gear ring 32. When the drive gear 33 drives the gear ring 32 to rotate, the coarse adjustment gear 36 does not contact the drive gear 33.

[0076] The gear ring connecting rod 35 is provided with a moving groove 351 and a connecting hole 352. The connecting hole 352 is located in the moving groove 351, and there are multiple connecting holes 352, such as... Figure 6 As shown, a connecting end 331 is provided on the drive gear 33. The connecting end 331 can move along the moving groove 351 and be inserted into the connecting hole 352, thereby connecting the drive gear 33 with the gear ring connecting rod 35. A bearing sleeve is provided in the connecting hole 352, and the connecting end 331 is connected to the connecting hole 352 through the bearing sleeve. The position of the connecting hole 352 is matched with the position of the gear ring 32 and the coarse adjustment gear 36. When the connecting end 331 is inserted into the connecting hole 352, the drive gear 33 can mesh with the inner ring of the coarse adjustment gear 36 or the gear ring 32, thereby driving the coarse adjustment gear 36 or the gear ring 32 to rotate.

[0077] The gear ring connecting rod 35 is also provided with a stop block 353, which is located on both sides of the moving groove 351. The stop block 353 is used to prevent the connecting end 331 from sliding out of the moving groove 351.

[0078] like Figure 7 As shown, a sliding groove 41 is provided on the fixed box 4, and the rotating rod 31 can move in the sliding groove 41. The position of the sliding groove 41 is matched with the moving groove 351. When the rotating rod 31 moves in the sliding groove 41, it can drive the connecting end 331 to move in the moving groove 351.

[0079] S34: Fine-tune the height of recognition unit 1.

[0080] Move the rotary rod 31 away from the fixed housing 4 so that the connecting end 331 moves out of the connecting hole 352. Move the rotary rod 31 along the slide groove 41 until the drive gear 33 meshes with the gear ring 32. Press the rotary rod 31 closer to the fixed housing 4 so that the rotary rod 31 enters the connecting hole 352. Rotate the rotary rod 31 so that the drive gear 33 drives the gear ring 32 to rotate, thereby moving the lifting rack 34 until the identification tip 11 contacts the processing line, completing the fine adjustment of the identification unit 1.

[0081] S35: Fixed identification unit 1.

[0082] Specifically, the limiting unit 2 includes a limiting platform 21 and a bolt 22. The limiting platform 21 is arranged on both sides of the lifting platform 13. The lifting platform 13 can move up and down along the limiting platform 21 as the lifting rack 34 moves. The bolt 22 passes through the limiting platform 21. By adjusting the bolt 22, the bolt 22 can be pressed against the lifting platform 13, thereby fixing the position of the lifting platform 13.

[0083] S36: The section where the processing line is located.

[0084] Specifically, the identification unit 1 also includes an identification platform 12, which is connected to the identification tip 11. A conversion plane 121 is provided on the identification platform 12. The conversion plane 121 and the tip of the identification tip 11 are coplanar in the horizontal direction, so that the plane information of the processing line is represented by the conversion plane 121.

[0085] S37: Adjust the identification tip 11 away from part 6.

[0086] Specifically, the identification unit 1 also includes a screw to move the identification tip 11 along the lifting platform 13, so that the identification tip 11 is away from the part 6, preventing the identification tip 11 from interfering with the processing of the part 6. The identification tip 11 is provided with a threaded hole 111, and the screw passes through the limiting piece 14 and is detachably connected to the threaded hole 111 to fix the position of the identification tip 11.

[0087] In step S4, specifically, the machining table 5 is placed on the machining machine tool so that the machining machine tool and the part 6 are positioned together, so that the machining machine tool can process the part 6.

[0088] In step S5, specifically, the position information of the transformation plane 121 is identified by the probe of the machining tool, thereby determining the position information of the plane where the machining line is located, and the part 6 is automatically processed by the machining tool according to the position information identified by the probe.
