Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a highly stable precision machining platform and its usage. Background Technology

[0002] Machining refers to the entire process of turning raw materials or semi-finished products into finished products during the production process. For machine production, this includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting and packaging, etc.

[0003] Precision machining mainly includes the following methods: ultra-precision cutting and grinding, such as turning and flying cutting using single-crystal diamond tools, and precision coordinate grinding, which directly removes optical surfaces through mechanical removal; special machining, such as electrical discharge machining, laser machining, and electrolytic machining, suitable for non-contact machining of high-hardness and complex surfaces; and composite machining and additive manufacturing, which combines additive and subtractive processes for the integrated molding of complex functional structures. All these processes place extreme demands on the dynamic stability, thermal stability, and static rigidity of the work platform; even slight platform drift or vibration can lead to workpiece scrap.

[0004] While existing precision machining platforms can achieve fully automated processing, workers often need to manually position the workpieces to be processed on the platform before processing. This results in additional labor costs, and if the workpiece is misplaced, it can directly lead to the scrapping of the workpiece.

[0005] Therefore, the aforementioned technical issues need to be resolved. Summary of the Invention

[0006] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a high-stability precision machining platform and its usage method, which solves the problem that in the prior art, workers often need to manually position the workpiece to be processed on the platform before processing, which leads to additional labor costs and can directly cause the workpiece to be scrapped when the workpiece is misplaced.

[0007] To achieve the above and other related objectives, the present invention provides the following technical solution:

[0008] A high-stability precision machining platform includes: a work platform, on the upper part of which a machine body is placed; a machining base is fixed inside the machine body; a receiving groove and a guide groove are respectively opened at the center of the machining base; the guide groove is located above the receiving groove; a control module and a power supply module are respectively installed inside the receiving groove; a feeding groove and a machining groove are respectively opened inside the two ends of the machining base; a feeding assembly is provided inside the feeding groove; an electric guide rail is installed inside the machining groove; a precision machining instrument is installed at the upper end of the electric guide rail; a pusher seat is slidably connected inside the guide groove; a top seat is provided at the upper end of the pusher seat; a rotating shaft is rotatably connected inside the top seat; and a clamping assembly is provided at the end of the rotating shaft away from the top seat.

[0009] To achieve the above technical solution, this invention integrates a feeding assembly, an electric guide rail driven precision machining instrument, and a positioning and clamping mechanism composed of a pusher seat and a clamping assembly within the machining table. This achieves full automation of the workpiece process from feeding and precise positioning to machining. The pusher seat slides along the guide groove, engaging with the clamping assembly driven by the rotating shaft. This allows for multi-degree-of-freedom fine-tuning and adaptive clamping of the workpiece, ensuring its precise alignment with the center of the machining groove and avoiding positional offset errors caused by manual placement. Simultaneously, the entire system relies on a high-rigidity, thermally stable work platform structure, enhancing dynamic stability during machining. This not only significantly reduces labor costs but also fundamentally reduces workpiece scrap due to positioning deviations, improving the consistency and yield of precision machining.

[0010] In one embodiment of the present invention, the feeding assembly includes a stop and a baffle. A stop is provided on one side of the inner side of the feeding trough, and baffles are provided at both ends of the inner side of the feeding trough. The stop and the baffle are both connected to the processing table. A material placement plate is slidably connected between the two baffles. A through groove is provided in the interior of the material placement plate near the stop. A first motor is installed on the side of the stop near the material placement plate. An eccentric shaft is provided at the output end of the first motor. The side of the eccentric shaft away from the first motor is located inside the through groove and is movably connected to the through groove.

[0011] In one embodiment of the present invention, a positioning groove is provided at the upper end of the material placement plate.

[0012] In one embodiment of the present invention, guide posts and screws are respectively provided on both sides of the inner side of the guide groove. The guide posts and screws are both connected to the processing table. The pusher seat is slidably connected to the guide posts. An internal threaded cylinder is rotatably connected inside the pusher seat and outside the screw. The inner side of the internal threaded cylinder is threadedly connected to the screw. A first bevel gear is provided on the outer side of the internal threaded cylinder.

[0013] In one embodiment of the present invention, a support shaft is rotatably connected to the center of the pusher seat, the upper end of the support shaft passes through the pusher seat and is provided with a support plate, the lower end of the support shaft is provided with a fourth bevel gear, and the top seat is located at the upper end of the support plate and is connected to the support plate.

[0014] In one embodiment of the present invention, a dual-axis motor is installed on the inner side of the push base and between the support shaft and the internal threaded cylinder. The two output ends of the dual-axis motor are respectively provided with a second bevel gear and a third bevel gear. The second bevel gear meshes with the first bevel gear, and the third bevel gear meshes with the fourth bevel gear.

[0015] In one embodiment of the present invention, the clamping assembly includes an L-shaped material frame, the end of the rotating shaft away from the top seat is provided with an L-shaped material frame, the lower end of the L-shaped material frame is provided with a fixing plate, the upper end of the L-shaped material frame is equipped with a telescopic cylinder, the telescopic end of the telescopic cylinder is provided with a pressure plate, and a finished product box is slidably connected to the inner side of the processing groove and located at the lower end of the L-shaped material frame.

[0016] In one embodiment of the present invention, a first spur gear is provided on the outer side of the rotating shaft near the top seat, and a second motor is installed inside the top seat and on the outer side of the rotating shaft. The output end of the second motor is provided with a second spur gear, and the second spur gear meshes with the first spur gear.

[0017] In one embodiment of the present invention, a guardrail is provided at the upper end of the work platform and on the outer side of the equipment platform, a step frame is provided at the lower end of one side of the work platform, a closed platform cover is rotatably connected to the upper end of the equipment platform, and hydraulic rods are installed at both ends of the inner side of the equipment platform and at the processing table, and the telescopic ends of the two hydraulic rods are rotatably connected to the closed platform cover.

[0018] The above technical solution enables the workpiece to be clamped by the clamping assembly during the workpiece transfer process. When the pusher seat slides inside the guide groove, it can simultaneously drive the workpiece to rotate laterally around the support shaft, changing the orientation of the workpiece from the feed groove to the processing groove. Then, in conjunction with the operation of the second motor, the workpiece can be driven to rotate longitudinally around the rotating shaft, achieving alignment and positioning between the workpiece and the precision machining instrument, and greatly improving the pass rate of the workpiece after processing.

[0019] A method of using a high-stability precision machining platform, comprising the following steps:

[0020] Step S1: Before processing begins, start the hydraulic rod to flip and open the closed platform cover, and align the external material conveying equipment with the feed chute.

[0021] Step S2: After feeding the workpiece into the positioning slot using the material conveying equipment, control the material placement plate to move upward.

[0022] Step S3: Use the clamping assembly to clamp the upward-moving workpiece, control the pusher seat to move towards the precision machining instrument, and during the movement of the pusher seat, the clamping assembly will rotate laterally.

[0023] Step S4: Start the second motor to control the longitudinal flipping motion of the clamping assembly, so that the workpiece is aligned with the precision machining instrument to start the machining operation. The finished workpiece falls into the finished product box for storage.

[0024] As described above, the high-stability precision machining platform and its usage method of the present invention have the following beneficial effects:

[0025] Through the overall structural design, the workpiece can be automatically transferred to the processing area for processing. This eliminates the need for manual positioning by staff, reducing labor costs and significantly decreasing the chance of workpiece misalignment, thus improving the workpiece processing qualification rate. During the workpiece transfer process, after the clamping assembly holds the workpiece and the pusher slides inside the guide groove, it can simultaneously drive the workpiece to rotate laterally around the support shaft, changing the workpiece's orientation from the feed groove to the processing groove. Then, in conjunction with the operation of the second motor, it can drive the workpiece to rotate longitudinally around the rotating shaft, achieving automatic alignment and positioning between the workpiece and the precision machining instrument.

Both guide posts 19 and screws 20 are connected to the machining table 7. The pusher seat 21 is slidably connected to the guide posts 19.

The second spur gear 34 meshes with the first spur gear 32.

[0047] Specifically, the method for using a high-stability precision machining platform includes:

[0048] Step S1: Before processing begins, start the hydraulic rod 6 to flip and open the closed platform cover 5, and align the external material conveying equipment with the feed chute 10.

[0049] Step S2: After feeding the workpiece into the positioning groove 15 using the feeding equipment, control the material placement plate 14 to move upward.

[0050] Step S3: Use the clamping assembly to clamp the upward-moving workpiece, control the pusher seat 21 to move towards the precision machining instrument 40, and during the movement of the pusher seat 21, the clamping assembly will rotate laterally.

The meshing of the second spur gear 34 with the first spur gear 32 drives the rotating shaft 31 to rotate, which in turn causes the clamping assembly to rotate 90 degrees around the rotating shaft 31. Figure 7 As shown, the transfer and positioning of the workpiece are completed, which facilitates the start of the precision machining instrument 40 to begin precision machining of the workpiece. After machining, the workpiece falls into the finished product box 41 for storage.
