Description

Technical Field

[0001] The utility model belongs to the technical field of polishing equipment, and more specifically, relates to a multi-axis and multi-station polishing machine. Background Art

[0002] Polishing and grinding refer to a processing method that uses mechanical, chemical, or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. Polishing and grinding are the last processes in the transmission manufacturing industry, and the surface quality of the workpiece can be further improved through polishing and grinding. In traditional processing, polishing and grinding are mainly completed manually, but its grinding efficiency is relatively low, time-consuming and laborious, and the labor cost is very high, resulting in a high processing cost of the workpiece.

[0003] With the continuous development of communication technology, the market demand for 3C digital products such as mobile phones, tablet computers, digital cameras, smart watches, and smart wearable electronic products is increasing. In order to improve the appearance quality, surface process aesthetics, and touch of these products, surface treatments such as grinding and polishing are required for the surfaces of these products. However, traditional manual polishing can no longer meet the requirements of these products for polishing processing efficiency and production cost. Moreover, with the continuous development of society and the continuous progress of technology, mechanized and automated production has gradually become a development trend. In order to meet the production needs, automated production has gradually been taken seriously by enterprises, and the development and realization of mechanical automation have led mechanical production into a new field.

[0004] However, the existing polishing equipment can usually process only one workpiece at a time, and the processing efficiency is still relatively low. Therefore, how to further improve the polishing processing efficiency of the workpiece is of great significance. After retrieval, although there are also patent studies that disclose multi-station polishing machines, that is, multiple workpieces can be processed simultaneously. For example, the application case with the Chinese patent application number 2018105329456 discloses a multi-station five-axis linkage numerical control polishing equipment. Using the equipment of this application case, multiple workpieces can be processed synchronously, and the workpiece clamping seat can improve the synchronous consistency of the rotation of multiple workpieces to a certain extent through the cooperation between the first divider, the fixed seat, the second servo motor, the first coupling, and the second coupling.

[0005] However, the processing accuracy of the existing multi-station intelligent polishing equipment is relatively low, especially it cannot effectively ensure the synchronism and consistency of the processing of each workpiece. For some products with high requirements for polishing quality, especially for products made of hard materials (such as stainless steel, titanium alloy, chromium molybdenum steel, etc.), it cannot meet their requirements for polishing accuracy. Summary of the Utility Model

[0006] The purpose of the present utility model is to overcome the deficiencies that existing polishing equipment can usually only polish one workpiece at a time, resulting in low processing efficiency, and that existing multi-station polishing equipment has relatively low processing accuracy and cannot meet the polishing requirements of some products with high polishing quality requirements.

A plurality of bearing seats are installed on the rotating top plate at intervals in the transverse direction. A plurality of flanges are installed on the rotating bottom plate at intervals in the transverse direction and are respectively coaxially arranged with the plurality of bearing seats. The upper end and the lower end of each transmission shaft are respectively rotatably connected to the bearing seat and the flange, and the motors for driving all the transmission shafts to rotate are controlled in a linkage manner.

It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of this application described here.

[0069] An embodiment of the present utility model provides a multi-axis and multi-station polishing machine. In combination with Figure 1 , the polishing machine includes a base 1, a transverse movement module 2, a longitudinal movement module 3, a vertical movement module 4, and a rotation module 5, wherein:

[0070] Both the transverse movement module 2 and the vertical movement module 4 are fixedly installed on the base 1. The longitudinal movement module 3 is reciprocally slidably installed on the transverse movement module 2 along the transverse direction; the rotation module 5 is reciprocally slidably installed on the longitudinal movement module 3 along the longitudinal direction, and a polishing fixture assembly station is provided on the rotation module 5. The polishing fixture is driven by the rotation module 5 to rotate self, and / or perform a flipping movement around the B axis parallel to the transverse movement module 2 (so that the workpiece flips in the direction of approaching or departing from the grinding module 7). A grinding module assembly station is provided on the vertical movement module 4 for assembling the grinding module 7 and driving the grinding module 7 to perform a lifting movement along the vertical direction.

[0071] When using the polishing equipment of this embodiment to grind and polish a workpiece, the polishing fixture is installed at the polishing fixture assembly station, the grinding module 7 is correspondingly installed at the grinding module assembly station, and the workpiece to be polished is fixed by the polishing fixture. The transverse movement module 2 and the longitudinal movement module 3 can drive the rotation module 5, the polishing fixture and the workpiece to move horizontally and vertically respectively. The vertical movement module 4 can drive the grinding module 7 to move up and down in the vertical direction. The rotation module 5 can drive the polishing fixture to drive the workpiece to rotate around its own axis and rotate around the B axis at the same time, so as to facilitate the alignment of the workpiece and polish different parts of the workpiece, which is beneficial to improving the processing efficiency without the need to disassemble and reinstall the workpiece.

[0072] As Figure 1 、 Figure 2 、 Figure 6 shown, in order to improve the processing efficiency and the production capacity of the equipment, in some embodiments, a plurality of polishing fixture assembly stations are provided on the rotation module 5. The plurality of polishing fixture assembly stations are spaced transversely (spaced along the same straight line). Each station is correspondingly installed with a transmission shaft 505 for driving the polishing fixture to rotate around its own axis, and the distance between adjacent transmission shafts 505 is 60 - 110 mm, further preferably 80 - 90 mm. A plurality of polishing consumables corresponding to the plurality of polishing fixtures are installed on the grinding module 7 (the specific structure of the grinding module 7 can be set according to actual needs, including the type, quantity and installation direction of the grinding heads, etc.). The rotation module 5 drives the plurality of polishing fixtures to rotate synchronously around their own axes and / or flip synchronously.

[0073] Although there are patents on multi-station polishing machines disclosed in the prior art, the polishing accuracy of existing multi-station polishing machines is relatively low, and there are prone to polishing dead corners. In particular, the consistency and synchronism of simultaneous processing of multiple products cannot be guaranteed. Therefore, the polishing requirements of some products with high polishing quality cannot be met. In view of the above deficiencies of existing multi-station polishing machines, on the one hand, in this embodiment, the layout of the five-axis movement is optimized, especially the four-axis movement (lateral movement, longitudinal movement, rotation in the B-axis direction, and self-rotation movement) of the workpiece to be processed can be achieved simultaneously. Thus, while improving the processing efficiency of the workpiece, the compactness of the equipment structure can be improved, the equipment volume can be reduced, and polishing of different positions of products with different shapes can be achieved, ensuring no polishing dead corners and the flatness of the polished surface, and further effectively guaranteeing the polishing accuracy of the product. On the other hand, in this embodiment, multiple polishing fixture assembly stations are distributed at intervals in the lateral direction, and the spacing between adjacent transmission shafts 505 is optimized, which is conducive to improving the structural compactness and stability of the rotation module 5. In particular, it can prevent the rotation module 5 from deforming due to the action of centrifugal force during the flipping process. Therefore, the stability, consistency, and concentricity of the synchronous rotation of multiple transmission shafts can be effectively guaranteed, further improving the polishing accuracy of the product. At the same time, the versatility of the polishing machine can be improved on the basis of minimizing the equipment size as much as possible, making it applicable to the polishing processing of different products.

[0074] In some other embodiments, the spacing D between adjacent transmission shafts is 1 / 3 to 1 / 7 of the length L of the rotation module, which can effectively prevent bending deformation during rotation due to the too large span of the rotation module, thus affecting the processing accuracy of simultaneous processing of multiple workpieces, and is conducive to further simultaneously ensuring the structural stability, equipment production capacity, and versatility of the entire equipment.

[0075] Specifically, in combination with Figure 3 , Figure 4 , Figure 6 and Figure 7As one of the preferred modes of the rotating module 5, the rotating module 5 comprises a fixed seat 503, a flip seat 504, a first rotating driving unit 501 and a second rotating driving unit 507, wherein the fixed seat 503 can be slidably mounted on the longitudinal moving module 3, and the fixed seat 503 can drive the entire rotating module 5 and the polishing fixture to reciprocate along the length direction of the longitudinal moving module 3. The two ends of the flip seat 504 are rotatably mounted on the fixed seat 503 through the B axis, and a plurality of polishing fixture assembly stations are arranged on the flip seat 504 and are distributed along the transverse interval, and the flip seat 504 is connected to the first rotating driving unit 501 by transmission, and the flip seat 504 is driven by the first rotating driving unit 501 to rotate relative to the fixed seat 503 around the B axis, so that all the polishing fixtures on the flip seat 504 can be driven to rotate together, so as to realize the synchronous rotation of the workpiece in the B axis direction. The transmission shaft 505 is connected to the second rotating driving unit 507 by transmission, and the second rotating driving unit 507 drives the plurality of transmission shafts 505 to drive the workpiece to rotate synchronously together.

[0076] More preferably, if Figure 5 , Figure 8 As shown, the fixed seat 503 includes a fixed base plate 5031 and two fixed side plates 5032 vertically installed at both ends of the fixed base plate 5031, and the fixed base plate 5031 is slidably installed on the longitudinal moving module 3 through the sliding seat 8; the flip seat 504 includes two rotating side plates 5041 arranged in parallel and opposite to each other, and a rotating top plate 5042 and a rotating base plate 5043 connected between the two rotating side plates 5041 and distributed in parallel along the vertical direction. The two rotating side plates 5041 are respectively rotatably installed in the inside of the two fixed side plates 5032, and the rotating top plate 5042 is used to install a supporting polishing fixture, and the transmission shaft 505 is rotatably installed on the rotating top plate 5042; the rotating base plate 5043 is used to install a second rotation drive unit 507, and the second rotation drive unit 507 adopts a motor, and the motor output shaft is parallel to the transmission shaft 505 and staggered along the longitudinal direction.

[0077] This embodiment further optimizes the design of the structure of the flip seat 504, thereby improving the structural stability and strength of the entire rotating module. In particular, the entire flip seat 504 can be balanced with the help of the parallel staggered distribution of the motor to further prevent it from bending and deformation, so as to ensure the stability of multiple workpieces during rotation and flipping during the polishing process, thereby ensuring the polishing accuracy of multiple workpieces.

[0078] Specifically, in this embodiment, the first rotation driving unit 501 adopts a motor (first rotation motor), which is installed on one side of the fixed seat 503, and its output end is transmission-connected to the flip seat 504 through the reducer 502.

[0079] As one of the implementation methods, combiningFigures 3 - 5 As shown, the second rotation driving unit 507 includes at least one motor (the first rotation motor). A driving synchronous pulley 508 is mounted on the output shaft of the motor. A driven synchronous pulley 509 is mounted on each transmission shaft 505. The driving synchronous pulley 508 is symmetrically connected to a plurality of driven synchronous pulleys 509 through a synchronous belt. The motor drives the driving synchronous pulley 508 to rotate, so that the plurality of driven synchronous pulleys 509 can be driven to rotate synchronously through the action of the synchronous belt, and then drive a plurality of polishing jigs and workpieces to be polished to rotate synchronously, ensuring the consistency of the processing of each workpiece.

[0080] In the above implementation manner, the second rotation driving unit 507 is further preferably configured to include at least two motors. Each motor drives two transmission shafts 505 to rotate synchronously through a synchronous belt, and linkage control is performed between all the motors, which is beneficial to further ensuring the consistency of the processing of all products. To further improve the stability of the entire flipping structure and the consistency of the processing of each workpiece, all the motors are installed at intervals along the transverse direction at the bottom of the rotating bottom plate 5043, and the output shafts of all the motors are symmetrically distributed on the same side of the transmission shaft 505.

[0081] It should be noted that when a single motor drives a plurality of different polishing jigs to rotate, a driving synchronous pulley 508 can be provided on the output shaft of the motor. The driving synchronous pulley 508 is connected to a plurality of driven synchronous pulleys 509 through the same synchronous belt, that is, the synchronous belt surrounds the outside of the driving synchronous pulley 508 and a plurality of driven synchronous pulleys 509; alternatively, a plurality of driving synchronous pulleys 508 can be provided on the output shaft of the motor, and each driving synchronous pulley 508 is respectively connected to a driven synchronous pulley 509 at a polishing jig assembly station through a synchronous belt.

[0082] In addition, the number of polishing jig assembly stations on the flipping seat 504 can be set according to the actual situation and actual needs. For example, it can be set to 2, 3, 4, etc. The number of motors in the second rotation driving unit 507 can be adjusted accordingly according to the number of polishing jig assembly stations on the flipping seat 504. For example, when the number of polishing jig assembly stations on the flipping seat 504 is 2 or 3, only one motor can be provided, and this motor simultaneously drives all the polishing jigs to drive the workpieces to be polished to rotate together; when the number of polishing jig assembly stations on the flipping seat 504 is 4 or more, it is further preferably to provide at least 2 motors, and each motor simultaneously drives at least two, preferably two driven synchronous pulleys 509 at the polishing jig assembly stations to rotate synchronously, and linkage control is performed between all the motors, so that the synchronous rotation of all the polishing jigs and the workpieces to be polished on the jigs can be effectively ensured.

[0083] Specifically, in the present embodiment, the number of polishing fixture assembly stations on the flip seat 504 is preferably 4, and they are evenly spaced along the length direction of the flip seat 504 (i.e., parallel to the B-axis direction), and the second rotation drive unit 507 includes 2 motors (second rotation motors), and the active synchronous wheel 508 on the output shaft of each motor is connected to the driven synchronous wheels 509 of two of the polishing fixture assembly stations through a synchronous belt, and the three are symmetrically distributed in a triangle (the active synchronous wheel 508 is located on the mid-perpendicular line of the line connecting the two driven synchronous wheels 509), thereby realizing the synchronous processing of multiple workpieces and improving the equipment's production capacity and processing efficiency, while also effectively ensuring the stability of the overall structure of the flip seat 504 and further improving the structural compactness of the equipment.

[0084] In addition, a support plate 5044 is fixedly provided between the two fixed side plates 5041 on the flip seat 504, and the support plate 5044 is located below the rotating top plate 5042. The upper and lower ends of the transmission shaft are respectively rotatably mounted on the rotating top plate 5042 and the support plate 5044, thereby further improving the rotation stability of the transmission shaft. In order to further improve the overall structural stability of the entire rotating module, the support plate 5044 is connected between the two rotating side plates 5041 and is flush with the rotating bottom plate 5043. The motor body is installed below the rotating bottom plate 5043, and the installation height of the active synchronous wheel 508 and the driven synchronous wheel 509 is the same (vertically flush distribution). However, it should be noted that the support plate 5044 and the rotating bottom plate 5043 are preferably two plates that are separately formed and flushly spaced, but an integral plate formed in one piece can also be directly used, that is, only one rotating bottom plate 5043 is provided, and the motor and the transmission shaft are installed on the rotating bottom plate 5043 along the longitudinal interval.

[0085] However, due to a certain gap between the synchronous wheel and the synchronous belt, a gap will be generated during twisting, which makes it difficult to find the transmission shaft angle, affecting the processing accuracy. Therefore, as another preferred embodiment, combined with Figure 7 , Figure 8 The second rotary drive unit 507 uses a motor (second rotary motor), and each transmission shaft 505 is connected to a servo motor through a reducer 515, and all motors are symmetrically staggered on both sides of the transmission shaft 505 in the longitudinal direction and are linked and controlled. This transmission method can not only effectively ensure the consistency of synchronous processing of multiple workpieces, but also help improve the processing accuracy of the workpieces, and increase the torque effect during polishing, thereby ensuring the polishing effect.

[0086] It should be noted that for the synchronous machining of multiple workpieces, how to further effectively ensure the machining accuracy is a difficulty in this application. In particular, the machining accuracy of existing multi-station polishing machines is relatively low, and they are usually only applicable to soft cutting (soft polishing of products with relatively soft hardness such as aluminum). In this embodiment, all the second rotating motors are installed on the top of the rotating bottom plate 5043, and a bearing seat 513 is installed on the rotating top plate 5042. A flange 514 coaxial with the bearing seat 513 is installed on the rotating bottom plate 5043. The upper end of the transmission shaft 505 is rotationally connected to the rotating top plate 5042 through the bearing seat 513, and its lower end is rotationally connected to the rotating bottom plate 5043 through the flange 514.

[0087] The combined cooperation of the bearing seat 513 and the flange 514 is beneficial to ensuring the levelness, parallelism and concentricity of the multiple transmission shafts 505 during rotation, preventing flexural deformation, thereby effectively improving the polishing accuracy, enabling the polishing machine to be applicable to the machining of products with relatively high polishing accuracy requirements. In particular, it can achieve hard cutting (hard polishing). At the same time, the motor can be directly installed on the top of the rotating bottom plate 5043.

[0088] Specifically, in this embodiment, the reducer 515 adopts a parallel shaft reducer, that is, the motor input shaft and the reducer output shaft (transmission shaft) are parallelly distributed, and the transmission shaft and the reducer are fixed through a flat key pin; preferably, the reducer 515 is installed on the rotating bottom plate 5043. The input end of the flange 514 is located above the rotating bottom plate 5043, and its output end is located below the rotating bottom plate 5043. The flange 514 is fixedly connected to the bottom of the output end of the reducer 515. The transmission shaft sequentially passes through the bearing seat 513, the reducer 515 and is rotationally connected to the flange 514 through a bearing to further improve the concentricity and anti-deformation ability of the transmission shaft.

[0089] In order to facilitate the installation of the polishing fixture, in some embodiments, the top of the transmission shaft 505 is connected with a locking chuck 6. The polishing fixture is installed and locked through the locking chuck 6. Thus, on the one hand, it is convenient for the installation of the polishing fixture, and on the other hand, different polishing fixtures can be replaced according to the different shapes of the products to be polished, so as to polish products with different shapes.

[0090] As a preferred method, the locking chuck 6 adopts a collet (elastic chuck), which includes an external connection nut 601 and an internal tapered chuck 602 (the collet is a standard part and can directly adopt the existing technology, so its structure and working principle will not be elaborated in detail). The top of the transmission shaft 505 is provided with a thread. The collet is threadedly connected to the top of the transmission shaft 505 through the external connection nut, and the inside of the top of the transmission shaft 505 is machined into a tapered hole structure matching the internal tapered chuck 602 of the collet (such as Figure 11As shown), by adopting the locking chuck 6, it is only necessary to insert the fixture to be polished into the tapered chuck, and the operation is relatively simple.

[0091] Furthermore, if Figure 12 , 13 As shown, in some embodiments, the polishing fixture includes a clamping portion 901 (the structure is not limited and can be replaced according to the shape and size of the product to be polished) for clamping the workpiece to be polished and a mounting portion 902 for mounting the polishing fixture. In order to further improve the parallelism of the installation between each transmission shaft and the workpiece and prevent deflection, the mounting portion 902 extends into the tapered chuck 602 inside the collet and continues to extend downward to the inside of the transmission shaft 505, and the upper part of the mounting portion is processed into a cylindrical structure matching the inner hole of the tapered chuck 602, and the lower part is processed into a tapered structure matching the tapered hole at the top of the transmission shaft 505 (the upper part of the mounting portion is a cylindrical rod structure, and the lower part is a tapered rod structure). In order to facilitate the tightening of the polishing fixture, the mounting portion 902 is a hollow structure, and a pull rod 512 is assembled inside it, and the pull rod 512 passes through the mounting portion 902 of the polishing fixture and the central axis hole of the transmission shaft 505 in sequence and is connected to the tightening cylinder 506. The tensioning cylinder 506 is used to tighten the pull rod 512, so that the polishing fixture and the workpiece can be clamped and fixed. When the polishing fixture needs to be replaced or disassembled, the tensioning cylinder 506 can be loosened.

[0092] Furthermore, the bottoms of all the tie rods 512 are connected to the same tensioning plate 510, and the tensioning cylinder 506 is installed on the rotating bottom plate, and the free end of its piston is fixedly connected to the tensioning plate 510. In order to ensure the stability of the structure and the consistency of the tensioning of each tie rod, the tensioning cylinder 506 is provided with two, which are symmetrically connected to the two ends of the tensioning plate 510 respectively.

[0093] Specific, combined Figures 9 - 11, in this embodiment, the transmission shaft adopts a double-layer sleeve structure, which includes an outer sleeve 5051 and an inner sleeve 5052. The inner sleeve 5052 is sleeved inside the outer sleeve 5051, and its top is processed into a tapered hole matching the tapered chuck 602 of the collet and the tapered rod structure at the lower part of the polishing fixture mounting part 902. Its bottom is a cylindrical hole structure matching the pull rod 512. The mutual cooperation between the tapered chuck 602 and the tapered rod at the lower part of the mounting part 902 and the tapered inner hole of the transmission shaft is beneficial to further ensure the parallelism of the polishing fixture and the workpiece installation and prevent skew. The top of the outer sleeve 5051 is provided with a thread matching the external connection nut of the collet, and the connection sections of the outer sleeve 5051 with the bearing seat and the flange are respectively processed with limiting steps. A limiting thread 5053 is processed at the lower connection of the outer sleeve 5051 and the bearing seat. The connection between the outer sleeve 5051 and the bearing seat is axially limited by the nut 516 and the limiting step at the upper part of the outer sleeve 5051; the bearing inside the flange 514 is axially limited by the limiting step at the lower part of the outer sleeve 5051. In order to further improve the waterproof effect, a waterproof part 511 is sleeved outside the transmission shaft above the bearing seat mounting hole.

[0094] As a further preferred solution of the embodiment of the present utility model, a plurality of grinding module assembly stations are provided on the vertical moving module 4. Different grinding modules 7 can be installed at different grinding module assembly stations according to needs, and the workpiece to be processed is respectively transported to different grinding module assembly stations through the cooperation of the horizontal moving module 2, the vertical moving module 3 and the vertical moving module 4, so that different polishing treatments (such as rough polishing, medium polishing, fine polishing, etc.) can be sequentially performed on the workpiece, realizing the continuous production (assembly line) of each polishing process of the workpiece, which is beneficial to further improve the processing efficiency. At the same time, different shapes and appearance requirements of products can also be processed by replacing the grinding module.

[0095] In some embodiments, the vertical moving module 4 includes a column and a tray. The column is vertically and fixedly installed on the base and is located on one side of the polishing fixture assembly station. The tray is slidably installed on the column up and down and is connected to the lifting drive unit, and a plurality of grinding module assembly stations are arranged at intervals along the length direction of the tray, so that the operating rate of the entire equipment can be effectively improved.

[0096] In this embodiment, the horizontal moving module 2, the vertical moving module 3 and the vertical moving module 4 all adopt a motor-screw mechanism for moving drive and a slider-guide mechanism for moving guidance. Since the motor-screw mechanism and the slider-guide mechanism are both prior arts, they will not be described in detail here. It should also be noted that other horizontal, vertical and lifting moving structures can also be used, which are not limited here, as long as the horizontal and vertical movement of the workpiece and the lifting movement drive of the grinding module can be realized.
