[0001] This utility model relates to the field of workpiece processing equipment technology, and more specifically, to a workpiece centering adjustment device. Background Technology

[0002] Currently, in CNC machining centers, CNC boring machines, deep hole drilling machines, EDM CNC electrical discharge machining machines and other equipment used for molds and non-standard parts, the workpieces processed can typically weigh from several hundred kilograms to tens of tons, which is quite heavy.

[0003] Due to the excessive weight of the workpieces, traditional robotic arms cannot directly grasp and load / unload them. Currently, manual operation combined with overhead cranes is mainly used to lift the workpieces onto the machine tool worktable. During the workpiece transfer process, the workpieces need to be moved to a transfer platform for alignment, and the placement, gripping position, and angle of the workpieces need to be centered and adjusted.

[0004] Currently, workpieces are mostly transferred using roller conveyor lines. Their function is limited to transmission, and the positioning of the workpieces relies entirely on the worker's visual observation and experience. It requires manual operation of overhead cranes to move and roughly position the workpieces. They do not have the ability to actively adjust to center the workpieces, making them inconvenient to use. Utility Model Content

[0010] There are multiple sliding mating parts that form multiple sliding arrays, and the multiple sliding arrays are spaced apart on the bearing surface.

[0011] Furthermore, the opposing centering mechanism includes a drive motor and positive and negative lead screws.

[0012] The drive motor is located below the support platform.

[0013] The positive and negative lead screws extend along the first direction and are connected to the drive motor for transmission.

[0014] Both of the moving parts are provided with transmission threads, and both of the moving parts are threaded with the positive and negative lead screws through the transmission threads, and the two moving parts are symmetrically arranged on both sides of the positive and negative lead screws.

[0015] Furthermore, the surface of the support platform is provided with a movable groove extending along the first direction.

[0016] The moving part includes a clamping part, a connecting part, and a transmission part. The clamping part is disposed on the bearing surface. The connecting part passes through the moving groove and one end is connected to the clamping part. The transmission part is disposed below the bearing platform and is connected to the other end of the connecting part. The transmission thread is disposed on the transmission part.

[0017] Furthermore, the picking and delivering mechanism also includes a driving component and a transmission component.

[0018] The drive unit is located on one side of the support platform.

[0019] The transmission component is disposed on the bearing surface and extends in a direction perpendicular to the first direction.

[0020] The pick-and-place component is connected to the transmission component to move along the extension direction of the transmission component.

[0021] Furthermore, the transmission component is a lead screw.

[0022] The transmission lead screw is embedded in the bearing surface and is positioned along the first direction at the center line of the bearing surface.

[0023] Furthermore, the sliding mating component is a universal ball.

[0024] The bearing surface is provided with multiple mounting slots.

[0025] Each of the omnidirectional balls is disposed in one of the mounting slots.

[0026] Furthermore, along a direction perpendicular to the first direction, one end of the bearing surface is the initial end, and the other end is the terminal end.

[0027] The pick-and-place component has an initial position, and when the pick-and-place component is in the initial position, the pick-and-place component is located at the initial end.

[0028] The workpiece centering adjustment device also includes a limiting component located at the terminal. The limiting component includes a limiting member that can move vertically to protrude from the bearing surface or retract below the bearing surface.

[0036] Beneficial effects: Specifically, in this utility model, the support platform can support the workpiece. After the workpiece is placed stably, two moving parts on both sides of the support surface move synchronously and at the same speed towards each other, thereby pushing, adjusting, and clamping the workpiece placed on the support surface to the center of the support surface. This eliminates the need for rough positioning by manual visual observation and experience, improving the accuracy and efficiency of centering adjustment. Multiple sliding mating parts on the support surface can prevent scratches and bumps on the bottom surface of the workpiece during centering. After centering adjustment, the two moving parts keep clamping the workpiece so that the pick-and-place mechanism can move to fit and dock with the centered workpiece, thereby realizing the transportation of the centered workpiece. The workpiece centering adjustment device provided by this utility model, after the workpiece is placed on the support surface, realizes the centering adjustment and clamping of the workpiece through the opposing centering mechanism, so that the pick-and-place mechanism can accurately dock with the workpiece and transfer the workpiece. This realizes automatic centering adjustment and transfer of the workpiece during transfer, eliminating the need for manual visual judgment and adjustment, making the adjustment more accurate and efficient.

[0046] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0047] Combination Figures 1 to 3 The workpiece centering adjustment device provided in this embodiment includes a support platform 100, a counter-centering mechanism 200, a pick-and-place mechanism 300, and a sliding mating part 400.

[0048] The support platform 100 has a support surface 110 for supporting workpieces. The opposing centering mechanism 200 includes two moving members 210 respectively disposed on both sides of the support surface 110 along a first direction. The two moving members 210 move synchronously and at the same speed on the support surface 110 along the first direction, moving closer or further apart from each other. The pick-and-place mechanism 300 includes a pick-and-place member capable of moving perpendicular to the first direction. The pick-and-place member is disposed on one side of the support surface 110 and located at the centerline of the support surface 110 in the first direction. The pick-and-place member is used to connect and fix the workpiece. There are multiple sliding mating members 400 forming multiple sliding arrays, which are spaced apart on the support surface 110.

[0049] Specifically, in this embodiment, the workpiece is placed on the bearing surface 110 and supported by the bearing platform 100.

[0050] After the workpiece is placed stably, the two moving parts 210 on both sides of the bearing surface 110 move towards each other synchronously and at the same speed, thereby pushing and adjusting the workpiece placed on the bearing surface 110 to the center of the bearing surface 110 until it is clamped. This eliminates the need to rely on manual visual observation and experience for rough positioning, thus improving the accuracy and efficiency of centering adjustment.

[0051] In this embodiment, the multiple sliding mating parts 400 provided on the bearing surface 110 can slide and engage with the bottom of the workpiece, thereby avoiding scratches and bumps to the bottom surface of the workpiece during the centering process.

[0052] After the workpiece is centered, the two moving parts 210 keep clamping the workpiece. The driving part in the pick-and-place mechanism 300 drives the pick-and-place part to move perpendicular to the first direction until the pick-and-place part comes into contact with and mates with the centered workpiece, thus connecting the pick-and-place part and the workpiece. Subsequently, the driving part drives the moving parts 210 to move again to move the workpiece, thereby realizing the transportation of the centered workpiece.

[0053] The workpiece centering adjustment device provided in this embodiment, after the workpiece is placed on the bearing surface 110, achieves centering adjustment and clamping of the workpiece through the opposing centering mechanism 200, so that the pick-and-place mechanism 300 can accurately dock with the workpiece and transfer the workpiece, realizing automatic centering adjustment and transfer of the workpiece during transfer, without the need for manual visual judgment and adjustment, and the adjustment is more accurate and efficient.

[0054] In this embodiment, the opposing centering mechanism 200 includes a drive motor 220 and a forward and reverse lead screw 230.

[0055] The drive motor 220 is located below the support platform 100. The positive and negative lead screws 230 extend along the first direction and are connected to the drive motor 220 for transmission. Both moving parts 210 are provided with transmission threads, and both moving parts 210 are threadedly engaged with the positive and negative lead screws 230 through the transmission threads. The two moving parts 210 are symmetrically arranged on both sides of the positive and negative lead screws 230.

[0056] Specifically, in this embodiment, the transmission structure formed by the drive motor 220 and the forward and reverse lead screws 230 can realize the synchronous driving of the two moving parts 210.

[0057] Because the threads on both sides of the lead screw 230 are in opposite directions, the two moving parts 210 can move synchronously and at the same speed towards or away from each other when the lead screw rotates. This ensures that the workpiece is subjected to uniform force and is symmetrically positioned during centering adjustment, avoiding workpiece offset or jamming caused by asynchronous movement. The drive motor 220 is located below the support platform 100, with a compact structure and stable transmission, further improving the accuracy and reliability of centering adjustment.

[0058] In this embodiment, the drive motor 220 and the lead screw 230 are connected by a chain drive. The drive motor 220 is a servo motor. After centering the workpiece using the drive motor 220, the width of the workpiece can be determined by observing the position and spacing of the two moving parts 210 on the lead screw 230, thereby achieving the measurement of the workpiece width.

[0059] In this embodiment, the surface of the support platform 100 is provided with a movable groove extending along a first direction.

[0060] The movable part 210 includes a clamping part 211, a connecting part, and a transmission part 212. The clamping part 211 is disposed on the bearing surface 110. The connecting part passes through the movable groove and one end is connected to the clamping part 211. The transmission part 212 is disposed below the bearing platform 100 and is connected to the other end of the connecting part. The transmission thread is disposed on the transmission part 212.

[0061] Specifically, in this embodiment, the movable component 210 is installed and guided through the movable slot on the support platform 100.

[0062] The clamping part 211 of the moving part 210 is located on the bearing surface 110 and directly contacts and pushes the workpiece. The transmission part 212 of the moving part 210 is located below the table and connected to the transmission mechanism to receive power. The connecting part of the moving part 210 moves stably in the moving groove and transmits the power of the transmission part 212 to the clamping part 211.

[0063] This structure effectively isolates the drive motor 220, transmission unit 212, and the workpiece's load-bearing area, preventing vibration, wear, or contamination generated during transmission from affecting the workpiece's positioning accuracy and surface quality. The moving slot not only provides precise guidance for the connecting parts, ensuring the linearity and stability of the overall movement of the moving component 210, but also makes the workpiece centering and clamping process more reliable and efficient, improving the overall rigidity and service life of the equipment.

[0064] Furthermore, in this embodiment, there are two moving slots arranged at intervals and in parallel. Correspondingly, each moving part 210 has two connecting parts arranged in the two moving slots, thereby realizing the two-point connection between the clamping part 211 and the transmission part 212, so that the structure of the moving part 210 is more stable and the transmission is more stable.

[0065] In this embodiment, the pick-and-place mechanism 300 further includes a drive component and a transmission component.

[0066] A drive component is located on one side of the support platform 100. A transmission component is located on the support surface 110 and extends perpendicular to the first direction. A pick-and-place component is drivenly connected to the transmission component to move along the extension direction of the transmission component.

[0067] Specifically, in this embodiment, the driving component, transmission component, and picking and delivering component constitute the picking and delivering mechanism 300 to realize the automatic transfer of the workpiece after centering adjustment.

[0068] The drive component acts as the power source, transmitting power to the pick-and-place component via the transmission component. This drives the pick-and-place component to move perpendicular to the first direction (i.e., the workpiece clamping direction). This allows the pick-and-place component to stably move along a predetermined path to the position where it aligns with the workpiece, thus achieving seamless integration between the centering adjustment and workpiece transfer processes. The entire process requires no manual intervention, improving workpiece transfer efficiency and avoiding positioning errors and potential safety risks associated with manual operation, ensuring the stability and reliability of the heavy workpiece transfer process.

[0069] It should be noted that in this embodiment, the pick-and-place component adopts an electromagnetic structure and docks and connects with the workpiece through magnetic attraction.

[0070] In this embodiment, the transmission component is a lead screw 310. The lead screw 310 is embedded in the bearing surface 110 and is positioned along the centerline of the bearing surface 110 in the first direction.

[0071] Specifically, in this embodiment, the transmission screw 310 is embedded at the center line of the bearing surface 110, and the picking and feeding component moves along the extension direction of the transmission screw 310 to realize the guidance and driving of the picking and feeding component.

[0072] This structure allows the pick-and-place component to move along the centerline of the bearing surface 110, ensuring precise and rapid docking between the pick-and-place component and the workpiece that has been centered and clamped, thus avoiding positional deviations during the docking process.

[0073] The mechanism in which the transmission screw 310 is embedded in the bearing surface 110 not only saves equipment space and makes the structure more compact, but also protects the transmission screw 310 from external impacts or contamination, thereby improving transmission stability and equipment lifespan.

[0074] In this embodiment, the sliding mating part 400 is a universal ball.

[0075] Furthermore, in this embodiment, the bearing surface 110 is provided with multiple mounting slots. Multiple omnidirectional balls are correspondingly positioned in the multiple mounting slots.

[0076] During the workpiece centering adjustment process, the omnidirectional ball array reduces frictional resistance through rolling. When the opposing centering mechanism 200 pushes the heavy workpiece, the omnidirectional ball array enables the workpiece to move horizontally smoothly, avoiding scratches, bumps, or dragging wear caused by direct contact between the bottom surface of the workpiece and the support platform 100, thus protecting the surface quality of the workpiece.

[0077] The distribution design of multiple mounting slots and multiple omnidirectional balls ensures the uniformity and stability of the omnidirectional ball support, preventing the workpiece from tilting or getting stuck during movement.

[0078] In this embodiment, along the direction perpendicular to the first direction, one end of the bearing surface 110 is the initial end, and the other end is the terminal end.

[0079] In this embodiment, the pick-and-place component has an initial position. When the pick-and-place component is in the initial position, it is located at the initial end. The workpiece centering adjustment device also includes a limiting component 500 located at the end. The limiting component 500 includes a limiting member 501, which can move vertically to protrude from the bearing surface 110 or retract below the bearing surface 110.

[0080] Specifically, in this embodiment, the end of the bearing surface 110 is provided with a liftable limiting component 500 to provide end positioning for the workpiece.

[0081] When the pick-and-place component transports the workpiece from the initial end to the terminal end, the limiting component 501 protruding from the bearing surface 110 can abut against and block the workpiece, keeping the workpiece in that position for subsequent fixing and transfer. At the same time, it can also prevent the workpiece from sliding off the bearing table 100 due to inertia or positioning deviation, ensuring the safety of operation.

[0082] When the equipment for transferring the workpiece arrives at the preset location and needs to connect to the workpiece, the limiting member 501 can retract below the bearing surface 110 so that the transfer equipment can contact the workpiece.

[0083] In this embodiment, the limiting member 501 is a limiting plate, and a detection probe is provided on the limiting plate located in the middle position.

[0084] The detection probe can scan the workpiece and identify it based on pre-marked markings to determine if it is the target workpiece.

[0085] In this embodiment, the limiting component 500 further includes a lifting cylinder 502. The limiting member 501 passes through the support platform 100 and is throttle-connected to the lifting cylinder 502.

[0086] Specifically, in this embodiment, the end of the support platform 100 is provided with multiple limiting holes, and the limiting member 501 passes through the limiting holes. The structure is compact, and the limiting holes can guide the limiting member 501 and provide certain support for the limiting member 501, so as to prevent the limiting member 501 from tilting after being pushed by the workpiece.

[0087] Furthermore, in this embodiment, the lifting cylinder 502 is used as the driving source for the limiting plate. The lifting cylinder 502 has the characteristics of smooth transmission and large output force, thus providing stable power for the lifting action of the limiting member 501.

[0088] In this embodiment, the workpiece centering adjustment device further includes a first detection element 101. The first detection element 101 is located at the initial end.

[0089] When the pick-up and delivery item is in the initial position, the first detection item 101 is located between the pick-up and delivery item and the moving item 210 and is located on one side of the pick-up and delivery item. The detection direction of the first detection item 101 is parallel to the first direction and faces the pick-up and delivery item.

[0090] Specifically, in this embodiment, the first detection element 101 can detect whether the workpiece is placed in a preset position, so as to avoid the situation where the width of the pick-and-place element is large and the width of the workpiece is small. When the workpiece is placed too far away from the pick-and-place element, the pick-and-place element will first abut against the moving parts 210 on both sides of the workpiece when docking with the workpiece, and will not be able to contact the workpiece, so that the workpiece cannot be transferred after the centering adjustment is completed.

[0091] In this embodiment, the first detection element 101 is located between the pick-up and delivery element and the moving element 210, and is located in the non-interference area on the side of the pick-up and delivery element, which avoids conflict with the movement path of the pick-up and delivery element and ensures the operation of the equipment.

[0092] In this embodiment, the workpiece centering adjustment device also includes a second detection element 102.

[0093] The second detection element 102 is located at the terminal. The detection direction of the second detection element 102 is parallel to the first direction and is oriented towards the moving route of the pick-up and delivery item.

[0094] Specifically, in this embodiment, a second detection element 102 is set in the terminal. The detection direction of the second detection element 102 is set to be parallel to the first direction and towards the moving route of the pick-up and delivery item. When the workpiece is transported to the terminal, the second detection element 102 can detect in time whether the workpiece has been moved to the correct position, realizing real-time, non-contact monitoring of whether the workpiece transported to the terminal is accurately in place.

[0095] The second detection component 102 can provide real-time feedback that the workpiece has been safely delivered to the terminal limit component 500, thereby triggering the lifting cylinder 502 to lift the limit component 501, or providing an accurate triggering basis for the equipment to enter the next working cycle.

[0096] It should be noted that in this embodiment, both the first detection element 101 and the second detection element 102 are through-beam sensors.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
