Description

Technical Field

[0001] This application relates to the field of optomechanics, and in particular to a dual-station processing optomechanic. Background Technology

[0002] The optical engine is a preliminary product of CNC machine tools. It consists of the main body and basic components such as the machine tool bed, saddle, worktable, column, guide rail, and headstock, but does not yet include hydraulic transmission components, pneumatic components, electric motors and electrical components, as well as CNC frame components. The design and manufacturing process of the optical engine is directly related to the quality, lifespan and reliability of CNC machine tools, and is of great significance to CNC machine tool processing.

[0003] To improve processing efficiency, existing optical processing machines typically employ a dual-station design. However, in actual processing, when the workpiece requires assembly-line processing, the processing coefficients of the two stations differ. During assembly processing, two rounds of loading and unloading operations are required to switch processing stations, making the operation cumbersome and hindering the improvement of the working efficiency of dual-station optical processing machines.

[0004] To address this, we propose a dual-station machining center that requires only one round of clamping and loading / unloading operations. This allows the workpiece to be processed simultaneously at both stations, as well as to be assembled at both stations, thus simplifying the operation process. Summary of the Invention

[0005] The purpose of this application is to improve the existing dual-station machining optical machine and provide a dual-station machining optical machine compared with the prior art, including a base with a stepped cross-section. A fixed clamping spindle is installed on one side of the top of the base, and a second servo motor is installed on the other side of the top of the base. A second guide rail is installed on the surface of the base, located between the fixed clamping spindle and the second servo motor. The output end of the second servo motor is connected to a second ball screw. A movable clamping spindle is connected to the surface of the second ball screw and is slidably connected to the second guide rail. The length of the second guide rail exceeds two-thirds of the cross-sectional length of the base. By using the cooperation of the second servo motor, the second ball screw and the second guide rail, the relative displacement between the movable clamping spindle and the fixed clamping spindle can be adjusted, thereby realizing the clamping of workpieces of different sizes.

[0006] A transverse frame is symmetrically mounted on the top of the base, located above the fixed clamping spindle. A translation frame is mounted above the transverse frame, and a lifting frame is mounted above the translation frame. A CNC turret is mounted on the surface of the lifting frame. The transverse frame, translation frame, and lifting frame can assist in the three-axis positioning adjustment of the conveying turret to ensure positioning accuracy during processing.

[0007] A through-tube is provided on the surface of the fixed clamping spindle near the moving clamping spindle. A magnet is fitted inside the through-tube. A rubber dust-proof strip is installed on the surface of the fixed clamping spindle, and a rubber tray is installed on the surface of the moving clamping spindle. When the magnet blocks the through-tube, the fixed clamping spindle and the moving clamping spindle can cooperate to achieve a stable clamping operation, which can assist in dual-station simultaneous processing. During dual-station assembly processing, the magnet falls off, the through-tube is unobstructed, and the No. 2 servo motor is started to drive the clamped workpiece through the through-tube to adjust the processing position of the CNC turret. This enables turning processing with reduced additional loading and unloading. During the processing, the movement of the workpiece through the through-tube can also be used to clean the surface debris of the workpiece, reducing the need for additional dust removal equipment and its associated costs.

[0008] Furthermore, the transverse frame includes a third servo motor mounted on the top of the base and located above the second servo motor. The top of the base is equipped with a third guide rail arranged opposite to it. The output end of the third servo motor is connected to a third ball screw, and the surface of the third ball screw is connected to a support plate that is fitted and slidably connected to the third guide rail. The top of the support plate is connected to the transverse frame to indirectly drive the CNC turret to move horizontally.

[0009] Furthermore, the top of the pallet is equipped with symmetrically arranged No. 4 guide rails, and the tail end of the pallet is equipped with No. 4 servo motor. The output end of the No. 4 servo motor is connected to No. 4 ball screw, and the surface of the No. 4 ball screw is connected to a slide frame. The surface of the slide frame is connected to the lifting frame, which is used to indirectly drive the CNC turret to move back and forth.

[0010] Furthermore, a servo motor is fixed at the top of the slide frame, and the output end of the servo motor is connected to a ball screw. The surface of the ball screw is connected to the CNC turret. The inner wall of the slide frame is equipped with guide rails located on both sides of the ball screw, which are used to indirectly drive the CNC turret to move up and down.

[0011] Furthermore, the inner wall of the tube is provided with a receiving groove, which is located directly below the magnetic steel plate. An electromagnet is installed on the bottom wall of the receiving groove, and electromagnetic rings electrically connected to the electromagnet are installed at equal intervals on the inner wall of the tube. After the electromagnet is activated, the magnetic steel plate falls into the receiving groove, which facilitates the penetration and movement of the workpiece. When the workpiece is magnetic, the electromagnetic rings in the activated state can provide a corresponding lifting effect to achieve a clamping effect, ensuring the stability of the workpiece when it is subsequently received by the CNC turret for machining.

[0012] Furthermore, an elastic magnetic sheet is connected to the surface of the dust baffle near the electromagnetic ring. When the electromagnetic ring is energized, there is a repulsive magnetic force between it and the elastic magnetic sheet. This repulsive force can suppress the dust baffle, preventing the end of the dust baffle from curling up after bending, so that the feed port can be stably attached to the surface of the clamped object for dust collection.

[0013] Optionally, a drive motor is installed inside the movable clamping spindle. The output end of the drive motor is connected to the surface of the rubber tray, which can help switch the processing angle of the workpiece surface while reducing the number of loading and unloading operations and manual adjustments.

[0014] Optionally, the dust baffle has a hollow interior design. An inlet is located near the tail end of the dust baffle surface, and outlets are symmetrically arranged on the surface of the dust baffle. A hollow cone is installed inside the dust baffle, with the side of the cone with the larger cross-section connected to the top of the inlet. To prevent debris from accumulating and clogging the inlet, debris inside the dust baffle on the surface of the workpiece falls into the gap between the cone and the inner wall of the dust baffle after passing through the cone. This ensures smooth feeding without clogging the outlet of the cone, and ensures that surface debris is collected smoothly during the movement of the workpiece.

[0015] Optionally, the surface of the dust baffle away from the elastic magnetic sheet is designed with a slope, and the slope angle does not exceed 15 degrees. The slope design can reduce secondary feeding when the dust baffle is discharging chips inside.

[0016] Furthermore, the base surface is provided with chip removal grooves, which are located below the dust baffle strip, for collecting debris from the surface of the workpiece cleaned by the dust baffle strip.

[0017] Compared to existing technologies, the advantages of this application are:

[0018] (1) The three-axis positioning adjustment of the conveying turret can be assisted by the transverse frame, translation frame and lifting frame to ensure the positioning accuracy during processing. When the magnetic steel plate blocks the through pipe, the fixed clamping spindle and the moving clamping spindle can cooperate with each other to achieve the corresponding stable clamping operation to assist in the simultaneous processing of the two stations. When the two stations are assembled and processed, the magnetic steel plate falls off and the through pipe is in a smooth state. The No. 2 servo motor is started to drive the clamped workpiece through the through pipe to adjust the processing position of the CNC turret. The turning processing is achieved on the basis of reducing the additional loading and unloading processing. During the processing, the surface debris of the workpiece can be cleaned by the behavior of the workpiece through the through pipe, reducing the addition and expenditure costs of other additional dust removal equipment.

[0019] (2) After the electromagnetic device is started, the magnetic steel plate falls into the storage slot, which facilitates the through-movement of the workpiece. When the workpiece is magnetic, the electromagnetic ring in the start-up state can provide a corresponding lifting effect to achieve the clamping effect, ensuring the stability of the workpiece when it is subsequently received by the CNC turret for machining.

[0020] (3) The repulsive force between the elastic magnetic sheet and the electromagnetic ring can suppress the dust strip, preventing the dust strip from bending and the end from sticking up, so that the feed port can be stably attached to the surface of the clamped object for dust collection.

[0021] (4) In order to avoid the accumulation of debris at the feed inlet and block the feed inlet, the debris inside the dust baffle strip on the upper surface of the workpiece falls into the gap formed between the cone hopper and the inner wall of the dust baffle strip after passing through the cone hopper. This can ensure that the feeding operation is carried out smoothly and will not block the discharge of the cone hopper, and ensure that the surface debris of the workpiece can be collected smoothly during the movement.

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] Example 1:

[0037] This invention provides a dual-station processing optical machine; please refer to [link / reference]. Figure 1-6 and Figure 8 The system includes a base 1 with a stepped cross-section. A fixed clamping spindle 2 is mounted on one side of the top of the base 1, and a second servo motor 41 is mounted on the other side of the top of the base 1. A second guide rail 42 is mounted on the surface of the base 1, located between the fixed clamping spindle 2 and the second servo motor 41. The output end of the second servo motor 41 is connected to a second ball screw 43. A movable clamping spindle 4 is connected to the surface of the second ball screw 43 and is slidably connected to the second guide rail 42. The length of the second guide rail 42 exceeds two-thirds of the cross-sectional length of the base 1.

[0038] Specifically, the second servo motor 41 drives the second ball screw 43 to rotate, which in turn drives the movable clamping spindle 4 to move laterally on the surface of the second guide rail 42, adjusting the clamping distance between it and the fixed clamping spindle 2 to accommodate the clamping of workpieces of different sizes.

[0039] A transverse frame 6 is symmetrically installed on the top of the base 1 above the fixed clamping spindle 2. A translation frame 8 is installed above the transverse frame 6. A lifting frame 3 is installed above the translation frame 8. A CNC turret 5 is installed on the surface of the lifting frame 3.

[0040] Specifically, relative movement can be achieved through the transverse frame 6, forward and backward movement can be achieved through the translation frame 8, and up and down movement can be achieved through the lifting frame 3, thereby driving the CNC turret 5 to achieve adjustment in the three-axis direction, so as to achieve more precise positioning and machining operations.

[0041] The fixed clamping spindle 2 has a through tube on its surface near the movable clamping spindle 4. A magnet plate 21 is fitted inside the tube. A rubber dustproof strip 22 is installed on the surface of the fixed clamping spindle 2, and a rubber tray is installed on the surface of the movable clamping spindle 4.

[0042] Specifically, during processing, if the dual-station independent processing is in progress, the magnetic steel plate 21 is in a blocked tube state to keep the end of the tube in a solid state, ensuring that the fixed clamping spindle 2 and the movable clamping spindle 4 can cooperate with each other to achieve the corresponding clamping operation, thus ensuring that the dual-station efficient processing can proceed smoothly.

[0043] If the dual-station assembly process is in progress, the workpiece is clamped by the fixed clamping spindle 2 and the movable clamping spindle 4. After processing the end of the workpiece closest to the movable clamping spindle 4, the solenoid is disconnected and the second servo motor 41 is turned on. At this time, the magnetic steel plate 21 loses its magnetic repulsion and lifting effect and falls into the receiving slot 24 under the action of gravity. At this time, the tube is hollow. The workpiece is pushed through the tube by the movable clamping spindle 4 under the action of the second servo motor 41 until the end processed first, which is close to the movable clamping spindle 4, moves to the position of the fixed clamping spindle 2. The corresponding processing operation is completed by another set of CNC turrets 5. The dual-station assembly process can be completed under the premise of one round of loading and unloading operations, simplifying the loading and unloading operation process.

[0044] After the dual-station processing is completed, pushing the workpiece into the conduit or continuing to push the workpiece after the dual-station assembly processing is completed can cause the dust baffle 22 to bend and fit against the surface of the workpiece, thereby cleaning up the waste after the workpiece surface is processed. This achieves the effect of simplifying processing and cleaning simultaneously, and improves the working efficiency of the dual-station processing optical machine.

[0045] The transverse frame 6 includes a third servo motor 61 mounted on the top of the base 1 and located above the second servo motor 41. A third guide rail 62 is mounted on the top of the base 1 and arranged opposite to it. The output end of the third servo motor 61 is connected to a third ball screw 63, and a support plate is connected to the surface of the third ball screw 63 and is slidably connected to the third guide rail 62. The top of the support plate is connected to the transverse frame 8.

[0046] Specifically, by driving the No. 3 servo motor 61 to rotate the No. 3 ball screw 63, the support plate can slide on the surface of the No. 3 guide rail 62, thereby adjusting the horizontal movement of the translation frame 8 and indirectly adjusting the distance between the two sets of CNC tool turrets 5.

[0047] The top of the pallet is equipped with symmetrically arranged No. 4 guide rails 82, and the tail end of the pallet is equipped with No. 4 servo motor 81. The output end of No. 4 servo motor 81 is connected to No. 4 ball screw 83, and the surface of No. 4 ball screw 83 is connected to a slide frame, and the surface of the slide frame is connected to the lifting frame 3.

[0048] Specifically, the fourth servo motor 81 drives the fourth ball screw 83 to rotate, which in turn drives the slide frame to move on the surface of the fourth guide rail 82, thereby indirectly driving the CNC turret 5 to move back and forth.

[0049] A servo motor 31 is fixed at the top of the slide frame. The output end of the servo motor 31 is connected to a ball screw 33, and the surface of the ball screw 33 is connected to the CNC turret 5. The inner wall of the slide frame is equipped with guide rails 32 located on both sides of the ball screw 33.

[0050] Specifically, the No. 1 servo motor 31 drives the No. 1 ball screw 33 to rotate, which indirectly drives the CNC turret 5 to move in the vertical direction, and then cooperates with the transverse frame 6 and the translation frame 8 to achieve positioning and adjustment in the three-axis direction.

[0051] Please see Figure 7 The inner wall of the tube is provided with a receiving groove 24, and the receiving groove 24 is located directly below the magnetic steel plate 21. An electromagnet is installed on the bottom wall of the receiving groove 24, and electromagnetic rings 23 electrically connected to the electromagnet are installed at equal intervals on the inner wall of the tube.

[0052] Specifically, when the workpiece is pushed into the through tube by the moving clamping spindle 4, the electromagnetic ring 23 is activated to generate an electromagnetic attraction effect, which provides an electromagnetic attraction effect to the magnetic metal workpiece, thereby playing a clamping supplement effect inside the through tube, making the workpiece more stable when it is processed by the subsequent CNC turret 5, and ensuring the processing effect.

[0053] Please see Figure 9 The dust-proof strip 22 has an elastic magnetic sheet 221 connected to its surface near the electromagnetic ring 23, and the electromagnetic ring 23 and the elastic magnetic sheet 221 have a repulsive magnetic force when the electromagnetic ring 23 is energized.

[0054] Specifically, after the elastic magnetic sheet 221 bends and adheres to the surface of the workpiece along with the dust baffle strip 22, the elastic magnetic sheet 221 is repelled by the electromagnetic ring 23, which can prevent the elastic magnetic sheet 221 from bending excessively. In turn, the repulsive action can squeeze the dust baffle strip 22, making the dust baffle strip 22 adhere more tightly to the surface of the workpiece, thereby achieving a better dust removal effect.

[0055] The movable clamping spindle 4 has a drive motor installed inside, and the output end of the drive motor is connected to the surface of the rubber tray.

[0056] Specifically, when the workpiece needs to be processed with an arc or a circle, the drive motor is started, which drives the rubber tray to rotate, indirectly driving the rotation of the workpiece held between the moving clamping spindle 4 and the fixed clamping spindle 2, reducing the need for manual angle adjustment.

[0057] The surface of the base 1 is provided with a chip removal groove 7, and the chip removal groove 7 is located below the dust baffle strip 22.

[0058] Specifically, the debris intercepted on the surface of the dust baffle 22 and the debris discharged from inside the dust baffle 22 can fall into the debris discharge groove 7, thus achieving the purpose of debris collection.

[0059] Example 2:

[0060] Please see Figure 9-11 Components identical or corresponding to those in Embodiment 1 are referred to by the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the dust baffle 22 has a hollow interior design. A feed inlet 223 is provided on the surface of the dust baffle 22 near the tail end. A discharge outlet 224 is provided on the surface of the dust baffle 22 symmetrically arranged with the feed inlet 223. A hollow cone 222 is installed inside the dust baffle 22, and the side surface with the larger cross-section of the cone 222 is connected to the top of the feed inlet 223.

[0061] Specifically, during dust removal by the dust baffle 22, debris from the surface of the workpiece enters the interior of the dust baffle 22 through the feed inlet 223. As the amount of debris increases, it enters the upper part of the hollow cone 222 through the cone 222. Since the discharge area of ​​the cone 222 at the end away from the feed inlet 223 is smaller than that at the other end, when the dust baffle 22 is in a bent and fitted dust removal state, in order to avoid debris accumulating and blocking the feed inlet 223, the debris inside the dust baffle 22 on the upper surface of the workpiece falls into the gap formed between the cone 222 and the inner wall of the dust baffle 22 after passing through the cone 222. This ensures that the feeding operation can proceed smoothly without blocking the discharge of the cone 222, and ensures that the surface debris of the workpiece can be collected smoothly during the movement. Meanwhile, the debris inside the dust baffle 22 on the lower surface of the workpiece can be discharged smoothly from the discharge outlet 224 with the help of the squeezing effect of the cone 222.

[0062] The surface of the dustproof strip 22 away from the elastic magnetic sheet 221 is designed with a slope, and the slope angle does not exceed 15 degrees.

[0063] Specifically, the slope design makes the discharge port 224 protrude from the feed port 223 in the vertical section, so that the debris inside the dust baffle 22 will not come into secondary contact with the feed port 223 when it is discharged through the discharge port 224.

[0064] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
