Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning device technology, specifically a synchronous positioning device for multi-station hydraulic clamps. Background Technology
[0002] Traditional single-workpiece positioning and clamping methods can only operate on one workpiece at a time, while multi-station hydraulic clamping synchronous positioning devices can position and clamp multiple workpieces at the same time. The machine tool does not need to perform frequent clamping, positioning and other auxiliary operations, which greatly reduces the auxiliary time of processing.
[0003] Existing synchronous positioning devices can only process one object at a time during use. In mass production scenarios, after each material is processed, a series of operations are required, such as loosening the clamp, taking out the processed material, putting in the material to be processed, and re-clamping and positioning. These auxiliary operations consume a lot of time.
[0004] To address this, a multi-station hydraulic clamp synchronous positioning device is proposed. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a multi-station hydraulic clamp synchronous positioning device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station hydraulic clamp synchronous positioning device, including a connecting plate. Multiple sets of cylinders are mounted on one side of the connecting plate. The output ends of the multiple sets of cylinders are connected to a round shaft. Two sets of clamping blocks are hinged to the top of the round shaft. A link is mounted on one side of each of the two sets of clamping blocks. A fixing block is connected to the end of the link away from the clamping block. A mounting box is fixedly connected to the end of the fixing block away from the link. The bottom of the mounting box is fixedly connected to the surface of the connecting plate. A storage block is mounted at the bottom of each of the two sets of clamping blocks. A horizontal plate passes through the bottom of the storage block. One side of the horizontal plate is fixedly connected to the surface of the connecting plate.
[0007] Preferably, each of the multiple sets of cylinders is fitted with a bracket, one side of which is fixedly connected to one side of the connecting plate. The bracket can be used to assist in fixing the cylinder from the side, limiting the radial sway of the cylinder, ensuring that the cylinder output end always pushes the round shaft in the preset direction, and avoiding the impact of cylinder displacement on the synchronous clamping accuracy of the clamping block.
[0008] Preferably, the circular shaft is located inside the mounting box, and the output end of the cylinder passes through the inside of the mounting box and is connected to the bottom of the circular shaft. The mounting box provides a fixed position for the fixing block and may also integrate some oil and air control elements to control the movement of the cylinder or to protect and organize the lines and pipelines of the hydraulic and pneumatic systems of the entire clamping device.
[0009] Preferably, a rubber ring is provided at the junction of the cylinder and the mounting box. Since the mounting box is equipped with integrated oil and air circuit components, the rubber ring can fill the gap between the cylinder output end and the through hole of the mounting box, preventing the leakage of hydraulic oil and compressed air in the box, ensuring stable hydraulic pressure, and avoiding insufficient cylinder driving force or delayed action due to pressure loss.
[0010] Preferably, one set of clamping blocks has a protrusion on one side, and the other set of clamping blocks has a groove on one side. The two sets of clamping blocks can be engaged, with the protrusion and groove engaging with each other to form an interlocking structure. This can restrict the displacement of the material laterally, especially for materials with smooth surfaces or irregular shapes. It can prevent the material from slipping or shifting due to force or vibration during processing, ensuring that the material is always in the preset processing position.
[0011] Preferably, both sets of clamping block supports are equipped with limiting blocks, and the surface of the horizontal plate has a circular hole, with the bottom of the limiting block penetrating through the inside of the circular hole.
[0012] Preferably, an inclined plate is fixedly connected to one side of the surface of the connecting plate. The inclined plate can serve as a shielding structure to prevent external debris from falling into the device. It can also organize the wiring and pipes around the device, making the overall layout more orderly and facilitating later maintenance.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a transmission component that moves under the drive of the cylinder output end as the clamping block action. It converts the linear motion of the cylinder into the rotational motion of the clamping block, driving two sets of clamping blocks to rotate around the hinge point, thereby realizing the opening and closing of the clamping block. The clamping block is a key component directly used to clamp materials. When the round shaft drives the clamping block to rotate, the two clamping blocks move towards each other to clamp the material, and move in opposite directions to release the material. The surface of the clamping block is added with wear-resistant material to improve the clamping effect and service life. The link serves to connect the clamping block and the fixing block, transmit the force during the movement of the clamping block, and can buffer the impact during the movement to a certain extent, ensuring the smoothness of the clamping block action. The fixing block facilitates the connection of the clamping block to the mounting box, ensuring the stability of the equipment. The placement block is used to place the material to be processed, providing a positioning and bearing platform for the material. The horizontal plate ensures the positional accuracy of the placement block in the vertical direction. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0016] The embodiments of this utility model will be described below based on its overall structure.
[0017] Please see Figures 1-4 A multi-station hydraulic clamp synchronous positioning device includes a connecting plate 1. Multiple sets of cylinders 2 are installed on one side of the connecting plate 1. The output ends of the multiple sets of cylinders 2 are connected to a round shaft 11. Two sets of clamping blocks 6 are hinged to the top of the round shaft 11. A link 7 is installed on one side of each set of clamping blocks 6. A fixing block 12 is connected to the end of the link 7 away from the clamping block 6. An installation box 4 is fixedly connected to the end of the fixing block 12 away from the link 7. The bottom of the installation box 4 is fixedly connected to the surface of the connecting plate 1. A placement block 8 is installed at the bottom of the two sets of clamping blocks 6. A horizontal plate 3 passes through the bottom of the placement block 8. One side of the horizontal plate 3 is fixedly connected to the surface of the connecting plate 1.
[0018] The connecting plate 1, a fundamental component of the entire device, supports and connects other parts. It provides mounting positions for components such as cylinders 2 and horizontal plates 3, ensuring the accuracy of relative positions between components and maintaining the stability of the entire structure. Multiple cylinders 2 serve as a power source, driving the circular shaft 11 through output force. Upon receiving commands from the control system, cylinders 2 can precisely control the magnitude and direction of the output force, thereby controlling the clamping and releasing actions of the clamping blocks 6 to adapt to the clamping requirements of different materials. Driven by the output of cylinders 2, the clamping blocks 6 move, acting as a transmission component, converting the linear motion of cylinders 2 into the rotational motion of the clamping blocks 6, driving the two sets of clamping blocks 6 to rotate around the hinge point, thus realizing the clamping action of the clamping blocks 6. The opening and closing mechanism includes clamping blocks 6, a key component directly used for clamping materials. When the round shaft 11 drives the clamping blocks 6 to rotate, the two clamping blocks 6 move towards each other to clamp the materials, and move in opposite directions to release the materials. The surface of the clamping blocks 6 is coated with wear-resistant material to improve the clamping effect and service life. The link 7 connects the clamping blocks 6 and the fixing block 12, transmits the force during the movement of the clamping blocks 6, and can buffer the impact during the movement to a certain extent, ensuring the smoothness of the clamping block 6's movement. This facilitates the fixing block 12 in connecting the clamping blocks 6 to the mounting box 4, ensuring the stability of the equipment. The placement block 8 is used to place the materials to be processed, providing a positioning and bearing platform for the materials. The horizontal plate 3 ensures the positional accuracy of the placement block 8 in the vertical direction.
[0019] Please see Figure 3 and Figure 4Each set of cylinders 2 has a bracket fitted on its surface. One side of the bracket is fixedly connected to one side of the connecting plate 1. The round shaft 11 is set inside the mounting box 4. The output end of the cylinder 2 passes through the inside of the mounting box 4 and is connected to the bottom of the round shaft 11. A rubber ring is set at the junction of the cylinder 2 and the mounting box 4. One set of clamping blocks 6 has a protrusion on one side, and the other set of clamping blocks 6 has a groove on one side. The two sets of clamping blocks 6 can be locked together. Limiting blocks 5 are installed on the brackets of both sets of clamping blocks 6. The surface of the horizontal plate 3 has a round hole 9. The bottom of the limiting block 5 passes through the round hole 9. An inclined plate 10 is fixedly connected to one side of the surface of the connecting plate 1. The brackets can be used to assist in fixing the cylinder 2 from the side, limiting the radial sway of the cylinder 2, ensuring that the output end of the cylinder 2 always pushes the round shaft 11 in the preset direction, and avoiding the impact of the displacement of the cylinder 2 on the synchronous clamping accuracy of the clamping block 6. The mounting box 4 provides a fixed position for the fixing block 12. On the other hand, it may also integrate some oil and air control elements to control the action of the cylinder 2. Alternatively, it can protect and organize the hydraulic and pneumatic systems of the entire clamping device, as the mounting box 4 has integrated oil and air circuit components inside. The rubber ring can fill the gap between the output end of the cylinder 2 and the through hole of the mounting box 4, preventing the leakage of hydraulic oil and compressed air in the box, ensuring stable hydraulic pressure, and avoiding insufficient driving force or delayed action of the cylinder 2 due to pressure loss. The protrusion and groove interlock to form an interlocking structure, which can restrict the displacement of materials laterally. Especially for materials with smooth surfaces or irregular shapes, it can prevent the materials from slipping or deviating due to force or vibration during processing, ensuring that the materials are always in the preset processing position. The round hole 9 guides the movement trajectory of the limit block 5, preventing the limit block 5 from deviating and causing limit failure, and further ensuring the synchronization and stability of the clamping block 6's action. If there are other equipment or pipelines near the device, the inclined plate 10 can serve as a shielding structure to prevent external debris from falling into the device. At the same time, it can also organize the wiring and pipelines around the device, making the overall layout more orderly and facilitating later maintenance.
[0020] Working principle: When positioning a workpiece is required, the workpiece is first placed on the surface of the placement block 8. Then, the cylinder 2 is activated as a power source, driving the circular shaft 11 to move through its output force. This shaft acts as a transmission component for the clamping block 6, converting the linear motion of the cylinder 2 into the rotational motion of the clamping block 6. This causes the two sets of clamping blocks 6 to rotate around the hinge point, thus opening and closing the clamping blocks 6. The clamping blocks 6 are key components directly used for clamping materials. When the circular shaft 11 drives the clamping blocks 6 to rotate, the two clamping blocks 6 move towards each other to clamp the material, and move in opposite directions to release the material. The surface is coated with wear-resistant material to improve the clamping effect and service life of the material. Link 7 connects the clamping block 6 and the fixing block 12, transmits the force during the movement of the clamping block 6, and can buffer the impact during the movement to a certain extent, ensuring the smoothness of the clamping block 6's movement. It also facilitates the fixing block 12 to connect the clamping block 6 to the mounting box 4, ensuring the stability of the equipment. The placement block 8 is used to place the material to be processed, providing a positioning and bearing platform for the material. The horizontal plate 3 ensures the positional accuracy of the placement block 8 in the vertical direction.
