Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and specifically to a multi-station automatic polishing machine for processing disc locks. Background Technology

[0002] In the product processing field, polishing is frequently required. The shapes of parts requiring polishing are diverse, with cylindrical products making up a large proportion. Polishing of cylindrical products is mostly done manually or semi-automatically. Manual polishing involves manually polishing the sides of the cylindrical product using polishing wheels or abrasive belts, which is inefficient, time-consuming, and produces uneven polishing. Semi-automatic polishing typically involves fixing the cylindrical product and then grinding its sides with a polishing wheel rotating around it. This method is also inefficient and complex, requiring the center of rotation of the polishing wheel to be aligned with the center of the cylindrical product. Typically, a polishing machine includes only one polishing wheel, and the feed rate is manually controlled to achieve the gradual processing from rough to fine grinding. However, the process from rough to fine grinding requires placing the workpiece on multiple machines with different grinding fineness levels for step-by-step grinding, resulting in a complex process, numerous steps, and time-consuming and labor-intensive operation, significantly increasing processing costs.

[0003] In response to this situation, Chinese utility model patent application number ZL201621383629.X (authorization announcement number CN206326478U) discloses an "Automatic Polishing Machine for Large Flat Discs", which includes a worktable and multiple polishing mechanisms evenly spaced around the worktable. The worktable includes a centrally rotatable disc, multiple polishing heads evenly arranged on the disc, and a first motor that drives the disc to rotate. The polishing mechanism includes a polishing arm, a fixed seat mounted on the polishing arm, a second motor on the fixed seat, and a polishing wheel driven by the second motor. This polishing machine uses multiple polishing mechanisms arranged around the polishing head, and the disc drives the workpiece to perform various rough polishing, fine polishing, or sand grinding operations to complete automatic polishing.

[0004] This type of automatic polishing machine has several shortcomings: The polishing head is mounted on a disc using a hydraulic base, and the hydraulic base drives the polishing head to swing back and forth and left and right for polishing. This structure is relatively complex. Especially when dealing with workpieces like disc locks that require multiple polishing processes, more polishing heads are often needed. However, an excessive number of polishing heads requires more hydraulic bases, making coordinated control difficult and increasing processing costs. Furthermore, the movements of the polishing heads are not synchronized; each head is driven independently, resulting in asynchronous movements that affect the processing accuracy between processes. Additionally, the workpiece is directly fixed to the polishing head without a dedicated fixing device, which can cause workpiece displacement during polishing, further reducing polishing accuracy and compromising product quality control. Further improvements are needed.

[0005] In addition, these polishing machines are not equipped with dust prevention devices, and the polishing process often generates a large amount of dust that is harmful to the human body, which in turn affects human health, and further improvements are needed. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a multi-station automatic polishing machine for disc locks that is highly efficient, highly accurate and capable of multi-station linkage, in light of the above-mentioned technical status.

[0007] The second technical problem to be solved by the present invention is to provide a multi-station automatic polishing machine for disc locks that can effectively prevent dust from flying, in view of the above-mentioned technical status.

[0008] The technical solution adopted by this invention to solve the first technical problem is: the multi-station automatic polishing machine for disc locks, comprising...

[0009] Workbench;

[0010] A disc is mounted on the worktable and rotates.

[0011] The first driving mechanism drives the disk to rotate intermittently;

[0012] Multiple clamps are provided and are spaced out on the disc along the circumference for positioning the disc lock;

[0013] Polishing components are spaced around the outer periphery of the disc and can polish and grind the disc lock that has been rotated to the corresponding work station.

[0014] The second drive mechanism drives the polishing assembly to move back and forth toward the disc lock positioned at the clamping head;

[0015] The third driving mechanism drives the polishing component to move up and down;

[0016] Each clamping head can rotate around its own axis. The bottom end of each clamping head extends to the bottom of the disc and is connected to a drive wheel. The worktable is provided with a fourth drive mechanism that can drive each drive wheel to rotate synchronously. The worktable is also provided with a disengagement mechanism that can disengage the clamping head from the fourth drive mechanism when it rotates to the loading position. The disc is provided with a pressing device that presses down and reinforces the disc lock positioned on the clamping head. The pressing device includes a first cylinder that can rotate intermittently in sync with each clamping head and a pressing head that is connected to the output end of the first cylinder and can rotate synchronously with the disc lock. The first cylinder is located above the clamping head. The top of the clamping head is also provided with a positioning block that can position the disc lock.

[0017] To better achieve linkage between the clamping heads and further improve polishing efficiency and precision, the fourth driving mechanism includes a first motor and a transmission belt connected to each of the driving wheels. The first motor drives the transmission belt to run, thereby driving each of the driving wheels to rotate, and in turn driving each of the clamping heads to rotate synchronously to form multiple linked polishing stations.

[0018] In order to enable the clamping head that runs to the loading station to stop in time for easy loading, preferably, the disengagement mechanism includes a support wheel located near the loading station. The outer side of the support wheel is supported on the inner side of the transmission belt, which drives the transmission belt to disengage from the drive wheel that rotates to the loading station, thereby stopping the clamping head located at the loading station from rotating.

[0019] To better drive the turntable to rotate intermittently, preferably, the first driving mechanism includes a second motor located below the turntable and a reducer connected to the second motor, with the output end of the reducer connected to the turntable.

[0020] To facilitate the polishing assembly's operation and optimize the installation structure, the system preferably includes a fixed base, a first mounting base, and a second mounting base. The fixed base is fixed to the worktable. The first mounting base is horizontally slidably mounted on the fixed base. The second mounting base is vertically slidably mounted on the first mounting base. A first guiding mechanism is provided between the fixed base and the first mounting base for guiding engagement. A second guiding mechanism is also provided between the first mounting base and the second mounting base for guiding engagement. A second driving mechanism is mounted on the fixed base and drivenly connected to the first mounting base. A third driving mechanism is mounted on the first mounting base and drivenly connected to the second mounting base. The aforementioned polishing assembly is mounted on the second mounting base.

[0021] In order to enable the easily damaged parts of the polishing assembly to be replaced quickly, preferably, the polishing assembly includes a third motor fixed on the second mounting base, a drive wheel driven and connected to the output end of the third motor, and a driven wheel rotatably mounted on the second mounting base, wherein a polishing abrasive belt is driven and connected between the drive wheel and the driven wheel.

[0022] In order to enable the polishing machine to have multiple polishing methods and polishing precision, preferably, the polishing component includes a third motor fixed on the second mounting base, and the output end of the third motor drives a polishing wheel.

[0023] The technical solution adopted by the present invention to solve the second technical problem is as follows: the workbench is provided with a plurality of dust collection devices for sucking up polishing dust, each of the dust collection devices is adjacent to its corresponding polishing component, and the dust collection device always slides back and forth following the moving direction of each polishing component.

[0024] To better recover dust, the dust recovery device preferably includes a dust cover, a suction pipe connected to the dust cover, and a fifth drive mechanism for driving the dust cover to move. The workbench is also equipped with a guide rail, and the bottom of the dust cover is connected to a sliding groove that can guide and cooperate with the guide rail. The fifth drive mechanism drives the dust cover to slide back and forth along the sliding groove, and one end of the suction pipe is connected to an external negative pressure air source.

[0025] For safety and to further prevent dust from spreading, preferably, a protective cover is also provided on the workbench. The four sides of the protective cover are provided with transparent side panels, and an openable door is also provided on the side wall of the protective cover adjacent to the loading station.

[0026] Compared with existing technologies, the advantages of this invention are as follows: By setting up a drive mechanism that can jointly drive the rotation of each rotary chuck, and by setting up a disengagement mechanism, the chuck rotating to the loading station can disengage from the drive mechanism and stop rotating. This ensures that the polishing stations can be linked while the loading station remains stationary, ultimately achieving a synchronous operation state of multi-axis linkage and single-axis clutch. This realizes the interconnection between the polishing stations and the loading station, achieving higher polishing accuracy and efficiency. Furthermore, by setting up a pressing device and a positioning clip on the chuck, in conjunction with the precise positioning of the solid-line circular lock, the movement of the circular lock during polishing is effectively prevented, thus preventing it from affecting processing accuracy and further improving the stability of polishing accuracy.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] like Figures 1-9 The diagram shows the preferred embodiment of the present invention. The multi-station automatic polishing machine for disc locks in this embodiment mainly includes a worktable 1, a disc 2, a clamping head 3, a polishing assembly 41, a first drive mechanism 5, a second drive mechanism 6, a third drive mechanism 7, a fourth drive mechanism 8, a release mechanism 11, a pressing device 9, a dust collection device 12, and a protective cover 13, etc.

[0038] like Figure 1As shown, a disc 2 is rotatably mounted on a worktable 1. Multiple clamping heads 3 are spaced apart circumferentially on the disc 2. Polishing components 41 surround the outer periphery of the disc 2 and are correspondingly positioned with each clamping head 3. Each set of polishing components 41 is equipped to polish the disc lock 4 positioned on the clamping head 3. A first driving mechanism 5 drives the disc 2 to rotate intermittently, a second driving mechanism 6 drives the polishing components 41 to move back and forth towards the disc lock 4 positioned on the clamping head 3, and a third driving mechanism 7 drives the polishing components 41 to move up and down. In this embodiment, there are six clamping heads 3 and five sets of polishing components 41, each corresponding to five clamping heads 3, forming five different polishing stations. The remaining clamping head 3 forms a loading station specifically for loading and unloading the disc lock 4 during the polishing process. Of course, the number of clamping heads 3 and polishing components 41 can be increased as needed. The pressing device 9 is set on the disc 2 and is used to press down and reinforce the disc lock 4 positioned on the clamping head 3.

[0039] refer to Figure 4 In this embodiment, the first driving mechanism 5 includes a second motor 51 located below the disk 2 and a reducer 52 connected to the second motor 51. The output end of the reducer 52 is connected to the disk 2. Through the cooperation of the second motor 51 and the reducer 52, the disk 2 is driven to rotate intermittently.

[0040] refer to Figures 2 to 4 Each clamping head 3 can rotate around its own axis, and the bottom end of each clamping head 3 extends to the bottom of the disc 2 and is connected to a drive wheel 31. The fourth drive mechanism 8 is located on the worktable 1 and is used to drive each drive wheel 31 to rotate synchronously. Since the clamping head 3 needs to be stationary when loading material at the loading station, a disengagement mechanism 11 is also provided on the worktable 1 to disengage the clamping head 3 from the drive of the fourth drive mechanism 8 when it rotates to the loading station. In this embodiment, the fourth drive mechanism 8 includes a first motor 81 and a transmission belt 82 connected to each drive wheel 31. The first motor 81 drives the transmission belt 82 to run, thereby driving each drive wheel 31 to rotate at the same speed, and then driving each clamping head 3 to rotate synchronously, ultimately forming multiple linked polishing stations.

[0041] like Figure 5 As shown, in this embodiment, the detachment mechanism 11 includes a support wheel 111 located near the loading station. The support wheel 111 is rotatably located below the workbench 1. In use, the outer side of the support wheel 111 supports the inner side of the transmission belt 82, driving the transmission belt 82 to detach from the drive wheel 31 that has rotated to the loading station, thereby stopping the clamping head 3 located at the loading station from rotating, so that the clamping head 3 at the loading station can always be in a stationary state to facilitate loading and unloading.

[0042] In this embodiment, as Figure 2 As shown, the pressing device 9 includes a first cylinder 91 and a pressing head 92 connected to the output end of the first cylinder 91. The end of the pressing head 92 can be adapted to the top of the disc lock 4. The first cylinder 91 is mounted on a bracket 93, which is fixed on the disc 2 and rotates synchronously with the disc, thereby ensuring that the first cylinder 91 and the clamping head 3 always rotate synchronously. A bearing is provided between the pressing head 92 and the output end of the first cylinder 91, so that the pressing head 92 can be rotatably mounted on the output end of the first cylinder 91. The first cylinder 91 is located above the clamping head 3, and a positioning block 32 for positioning the disc lock 4 is provided on the top of each clamping head 3. When the disc lock 4 is positioned on top of the clamping head 3 by the positioning block 32, the first cylinder 91 can be driven to move its output end downward, pressing the lower pressure head 92 onto the upper end of the disc lock 4 and causing it to rotate together with the disc lock 4. This ensures that the disc lock 4 is firmly and accurately positioned on the clamping head 3, guaranteeing that the disc lock 4 will not shift during the subsequent polishing process, thereby improving the polishing quality.

[0043] like Figure 6 As shown, the workbench is also equipped with a mounting structure for mounting the polishing assembly 41, specifically including a fixed base 42, a first mounting base 43, and a second mounting base 44. In this embodiment, the fixed base 42 is fixedly mounted on the workbench 1, the first mounting base 43 is horizontally slidably mounted on the fixed base 42, and the second mounting base 44 is vertically slidably mounted on the first mounting base 43. A first guide mechanism 45 is provided between the fixed base 42 and the first mounting base 43 to guide and engage during movement, and a second guide mechanism 46 is also provided between the first mounting base 43 and the second mounting base 44 to guide and engage during movement. In this embodiment, the first guide mechanism 45 uses a guide post and a guide hole arranged horizontally to achieve guiding engagement, allowing the first mounting base 43 to slide horizontally and reciprocate. The second guide mechanism 46 uses a slide rail and a slide groove to allow the second mounting base 44 to slide vertically along the first mounting base 43. The second drive mechanism 6 is mounted on the fixed base 42 and driven by the first mounting base 43. The second drive mechanism 6 uses a servo motor or cylinder to drive the movement of the first mounting base 43. The third drive mechanism 7 is mounted on the first mounting base 43 and driven by the second mounting base 44, such as... Figure 6 As shown, the third drive mechanism 7 uses a cylinder drive to achieve the up-and-down sliding of the second mounting base 44. Of course, the third drive mechanism 7 is not limited to cylinder drive; other equivalent drive methods can also be used to drive the second mounting base 44 to slide up and down.

[0044] like Figure 6As shown, in this embodiment, the polishing assembly 41 is mounted on the second mounting base 44. The polishing assembly 41 includes a third motor 411 fixed to the second mounting base 44, a driving wheel 412 driven by the output of the third motor 411, and a driven wheel 413 mounted on the second mounting base 44. A polishing belt 414 is driven between the driving wheel 412 and the driven wheel 413. The polishing belt 414 can be designed as a belt pulley drive to drive the driving wheel 412 and the driven wheel 413. To ensure that the processes at each polishing station are different, allowing for sequential rough polishing and fine polishing, different polishing accuracies can be achieved by installing polishing belts 414 of different specifications and fineness. Figure 7 As shown in this embodiment, in order to enable the polishing machine to have multiple polishing methods and polishing precision, a polishing wheel 415 can also be directly set at the output end of the third motor 411 to achieve higher precision polishing.

[0045] refer to Figure 8 In this embodiment, in order to better recover dust and prevent the dust generated during polishing from flying around, the workbench 1 is equipped with multiple dust recovery devices 12 for sucking up polishing dust. Each dust recovery device 12 is adjacent to its corresponding polishing component 41, and the dust recovery device 12 always slides back and forth following the movement direction of each polishing component 41. The dust recovery device 12 includes a dust cover 121, a suction pipe 122 connected to the dust cover 121, and a fifth drive mechanism 123 for driving the dust cover 121 to move. The workbench 1 is also equipped with a guide rail 124, and the bottom of the dust cover 121 is connected to a sliding groove 125 that can guide and cooperate with the guide rail. The fifth drive mechanism 123 drives the dust cover 121 to slide back and forth along the sliding groove 125. The fifth drive mechanism 123 is driven by a cylinder to drive the dust cover 121 to move. One end of the suction pipe 122 is connected to an external negative pressure air source. The dust generated during the polishing of each polishing component 41 is collected by the dust cover 121 and discharged through the suction pipe 122 by the negative pressure air extraction method.

[0046] In addition, such as Figure 9 As shown in this embodiment, a protective cover 13 is also provided on the workbench 1. The four side walls of the protective cover 13 are provided with transparent side panels 131. An openable door 132 is also provided on the side wall of the protective cover 13 adjacent to the loading station. The protective cover 13 can effectively prevent dust from spreading and is also safer to use.

[0047] In this embodiment, a control element is also provided on the workbench 1, and each drive mechanism is electrically connected to the control element to realize the coordinated operation of multiple components.

[0048] It should be noted that in the description of this embodiment, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.
