Description

Technical Field

[0001] This utility model relates to the technical field of profile transfer equipment, specifically to a profile gripping device. Background Technology

[0002] Window and door frame profiles are the core structural materials used to manufacture building door and window frames. They are typically made of aluminum alloy, PVC, wood, or composite materials through processes such as extrusion and injection molding. Their cross-sectional design features specific geometric shapes, serving functions such as structural support, installation and fixation, and sealing and insulation. They must meet requirements for strength, durability, airtightness, and aesthetics, and are processed in long, semi-finished strips on the production line for further processing such as cutting, milling, and corner assembly. In automated processing, gripping devices are key equipment for handling, positioning, and transferring window and door frame profiles.

[0003] However, current gripping devices still have several problems: for example, current gripping equipment generally uses suction cup clamps or flat plate clamps, which have high requirements for the surface flatness of the profiles, which can easily cause the profiles to fall off or be squeezed and damaged; the lifting mechanism of the gripping device generally uses multiple power components to control the lifting, which increases the overall weight of the gripping head and is less economical.

[0004] Therefore, in order to address the above problems, a profile gripping device is proposed. Utility Model Content

At the same time, the inner side of the arc shape of the movable gripper can cooperate with the surface of the fixed plate to form a space for accommodating the large-area cross-section side of the profile, avoiding the squeezing of traditional flat plate clamps. When gripping profiles with large-area cross-section side, it is not even necessary to clamp the profile surface. It is only necessary to hold the large-area cross-section side of the profile in the inner space of the movable gripper to achieve gripping, and it will not fall off. At the same time, there is no pressure on the profile surface, avoiding damage to the profile, and it is more economical and practical. Attached Figure Description

[0035] In an optional embodiment, the gantry truss 1 includes columns 101 and an upper truss 102, both made of square steel tubing.

[0036] In an optional embodiment, the translation component 2 includes a translation rail 201 and a translation rack 202, both of which are arranged on the upper truss 102 along the length direction of the upper truss 102. At least two translation rails 201 are provided to meet the support requirements. Translation sliders are slidably arranged on each translation rail 201. The translation sliders are connected to the crossbeam 3 to make the crossbeam 3 slide. A translation force member 203 is provided on the crossbeam 3. The translation force member 203 is a motor. A translation gear 204 is coaxially arranged at the output end of the translation force member 203. The translation gear 204 meshes with the translation rack 202 to drive the crossbeam 3 to slide, thereby meeting the requirement of the gripper component 9 to move laterally.

[0037] In an optional embodiment, the extension assembly 4 includes an extension power component 401, which is a motor, slidably disposed at one end of the crossbeam 3. An extension gear 402 is coaxially disposed at the output end of the extension power component 401. The extension gear 402 meshes with an extension rack 403. The extension rack 403 is disposed on the extension beam 5, and the length direction of the extension rack 403 is consistent with the length direction of the extension beam 5. An extension slide rail 404 is disposed on the side of the extension beam 5 along its length direction. At least two extension slide rails 404 are provided, and extension sliders are slidably disposed on each of the extension slide rails 404. The extension sliders are connected to the crossbeam 3 so that the extension beam 5 slides along its length direction, resulting in greater longitudinal displacement of the gripper assembly 9 and better practicality.

[0038] In an optional embodiment, the moving component 6 includes a moving slide rail 601 and a moving rack 602, both of which are arranged on the extension beam 5 along the length direction of the extension beam 5. At least two moving slide rails 601 are provided, and a moving slider is slidably arranged on each of the moving slide rails 601. The moving slider is connected to the outer sliding seat 10 and is used to drive the outer sliding seat 10 to slide. A moving power component 603 is provided on the outer sliding seat 10. The moving power component 603 is a motor. The output end of the moving power component 603 is coaxially connected to a moving gear 604. The moving gear 604 meshes with the moving rack 602 so that the outer sliding seat 10 can move along the length direction of the extension beam 5, which facilitates the gripper assembly 9 to grasp.

[0039] In an optional embodiment, the outer sliding seat 10 is slidably connected to the middle sliding seat 11, and the middle sliding seat 11 is slidably connected to the inner sliding seat 12. The sliding directions of the middle sliding seat 11 and the inner sliding seat 12 are parallel to each other and perpendicular to the ground, so as to drive the gripper assembly 9 to move up and down to grip the profile.

[0040] In an optional embodiment, the lifting assembly 7 includes a lifting power component 701, which is a motor, and is mounted on the outer sliding seat 10. The output end of the lifting power component 701 is connected to a lifting screw 702. The lifting screw 702 is rotatably mounted on the outer sliding seat 10, and the axis of the lifting screw 702 is parallel to the sliding direction of the middle sliding seat 11 and the inner sliding seat 12. A nut 703 is threaded onto the lifting screw 702 and is mounted on the middle sliding seat 11. The rotation of the lifting screw 702 causes the nut 703 to move, thereby causing the middle sliding seat 11 to slide. Preferably, the output end of the lifting power component 701 is coaxially provided with a main synchronous pulley, and one end of the lifting screw 702 is coaxially provided with a secondary synchronous pulley. The main synchronous pulley and the secondary synchronous pulley are connected by a synchronous belt drive to transmit power.

[0041] In an optional embodiment, the linkage assembly 8 includes linkage pulleys 801. Linkage pulleys 801 are rotatably mounted at both the upper and lower ends of the central sliding seat 11. The axes of the linkage pulleys 801 are perpendicular to the axis of the lifting screw 702. The linkage pulleys 801 are connected by a linkage timing belt 802. An outer positioning block 803 and an inner positioning block 804 are respectively provided on both sides of the linkage timing belt 802. The outer positioning block 803 connects to the outer sliding seat 10, and the inner positioning block 804 connects to the inner sliding seat 12. Positioning block 803 and inner positioning block 804 move in opposite directions when moving with the linkage synchronous belt 802. The movement of the middle sliding seat 11 drives the linkage pulley 801 to move. Since the outer positioning block 803 is fixed to the outer sliding seat 10, the inner positioning block 804 moves relative to the outer positioning block 803 to drive the inner sliding seat 12 to move. Thus, the middle sliding seat 11 and inner sliding seat 12 can be moved simultaneously by a single power component, reducing the number of power components and improving economy.

[0042] In one optional embodiment, buffer blocks 805 are provided at both the upper and lower ends of the outer positioning block 803. The buffer blocks 805 are made of a flexible material such as rubber. Limiting blocks 806 are provided at both the upper and lower ends of the middle sliding seat 11 corresponding to the positions of the buffer blocks 805. These are used to limit the movement range of the middle sliding seat 11. In another embodiment, limiting blocks 806 are also provided at both the upper and lower ends of the inner sliding seat 12. A corresponding buffer block 805 is also provided at the bottom end of the middle sliding seat 11 corresponding to the position of the limiting blocks 806 on the inner sliding seat 12. This is used to limit the movement range of the inner sliding seat 12 and prevent the outer sliding seat 10, the middle sliding seat 11, and the inner sliding seat 12 from disengaging from each other.

[0043] In an optional embodiment, the gripper assembly 9 includes a fixed plate 901. Fixed plates 901 are provided at both ends of the mounting plate 13. A gripping power component 902 is rotatably mounted on the fixed plate 901. The gripping power component 902 is a cylinder. The output end of the gripping power component 902 is rotatably connected to a movable gripper 903. One end of the movable gripper 903 is rotatably mounted on the fixed plate 901. The other end of the movable gripper 903 cooperates with the fixed plate 901 to grip the profile. The two sets of gripper assemblies 9 ensure the stability of the gripping.

[0044] In an optional embodiment, the movable gripper 903 is configured as an arc shape. One end of the movable gripper 903 is rotatably disposed in the middle of the fixed plate 901, and the other end of the movable gripper 903 is used to contact the profile. A rubber layer is provided on the end of the movable gripper 903 and the inner side of the arc shape to increase friction while avoiding scratching the profile. One side of the arc-shaped opening of the movable gripper 903 faces the fixed plate 901, and a space is left between the movable gripper 903 and the fixed plate 901 to accommodate the side of the profile with a larger cross-sectional area. The output end of the gripping power component 902 is rotatably connected to the middle of the movable gripper 903. Friction textures 904 are provided on the surface of the fixed plate 901 corresponding to the arc-shaped opening of the movable gripper 903. The profile can be gripped by applying force to the movable gripper 903 or by the contact between the movable gripper 903 and the fixed plate 901.

[0045] Working principle: First, the horizontal position of the gripper assembly 9 is adjusted by the translation component 2, the extension component 4, and the moving component 6. Then, the height position of the gripper is adjusted by the lifting component 7. The lifting component 7, in conjunction with the linkage component 8, enables the middle sliding seat 11 and the inner sliding seat 12 to move simultaneously by a single power component, resulting in better economy. The gripping power component 902 is retracted first, and the movable gripper 903 is opened so that the side of the fixed plate 901 close to the movable gripper 903 contacts the side of the profile. Then, the gripping power component 902 is extended, and the profile is clamped by the arc-shaped movable gripper 903 in conjunction with the fixed plate 901. Then, the profile is moved, resulting in better practicality.
