[0025] This utility model proposes an automatic leveling tooling fixture.
[0026] like Figures 1 to 2 As shown in one embodiment of this utility model, the automatic leveling fixture includes a base 1 connected to a conveying device at one end. An adjustment platform is provided on the upper end of the base 1. The adjustment platform includes a fixed base 2 and a conveying platform 3. The fixed base 2 is fixedly connected to the base 1. The upper end of the fixed base 2 is provided with a first sliding groove 21 facing the conveying device. The conveying platform 3 is embedded in the first sliding groove 21 and slidably connected to the fixed base 2, so that the conveying platform 3 can perform telescopic movement relative to the conveying device in order to receive the product sent by the conveying device. A position adjustment device 4 is provided on the base 1 for adjusting the front-back, left-right position of the product on the conveying platform 3. The base 1 is also provided with a posture adjustment device 5 for adjusting the posture of the product. When the product is transported to a preset position by the conveying platform 3, the posture adjustment device 5 adjusts the posture of the product, and then the position adjustment device 4 adjusts the position of the product.
[0027] The position adjustment device 4 includes a lifting structure and a clamping structure. The lifting structure is connected to the clamping structure via a telescopic rod, which extends into the conveyor table 3. The lifting structure is fixedly connected to the base 1, and the clamping structure is rotatably connected to the telescopic rod. A camera positioning device is installed on the clamping structure to determine the position of the product. Then, the lifting structure and the telescopic rod are controlled to move the clamping structure to the appropriate position. The clamping structure is then rotated, and the lifting structure is lowered. The clamping angle is rotated again to the preset position to achieve the purpose of straightening the product. Both the lifting structure and the telescopic rod can be implemented by cylinders. The clamping structure can be a combination of a motor and two clamping parts. The motor controls the movement of one of the clamping parts to achieve the clamping function, and the rotation of the clamping parts can be achieved by the motor. The posture adjustment device 5 can be composed of a lifting structure, a telescopic rod, and a lever. The structure of the lifting structure and the telescopic rod can be similar to the lifting structure and telescopic rod of the position adjustment device described above. The lever is rotatably connected to the telescopic rod via a motor, and the product is straightened by controlling the lever.
[0028] In this embodiment, the conveyor 3 is controlled to extend and retract through the first chute 21 to receive and transport products. After the product is conveyed to the preset position by the conveyor 3, the posture adjustment device 5 adjusts the posture of the product to be in the preset posture. Then, the position adjustment device 4 adjusts the position of the product up, down, left and right to achieve precise adjustment of the product position, which is convenient for the next process.
[0029] Furthermore, the tooling fixture includes: a base 1, welded from aluminum alloy profiles, with a guide roller at one end that docks with the conveyor belt to ensure that the conveyor table 3 smoothly receives and delivers products; an adjustment table, consisting of a fixed base 2 and a conveyor table 3, the fixed base 2 being fixed to the middle of the base 1 by bolts, with a dovetail-shaped first slide groove 21 machined on its upper surface, and a matching dovetail slider at the bottom of the conveyor table 3, which is embedded in the first slide groove 21 to achieve sliding along the conveying direction (X-axis); a position adjustment device 4, including a front-to-back adjustment mechanism 41 (X-axis direction) and a left-to-right adjustment mechanism 42 (Y-axis direction), the front-to-back adjustment mechanism 41 being symmetrically installed at both ends of the X-axis of the base 1, and the left-to-right adjustment mechanism 42 being distributed on both sides of the Y-axis of the base 1; and an attitude adjustment device 5, located on the right side of the base 1, including two sets of staggered push rod 513 assemblies for correcting the rotational deviation of the product around the Z-axis. The product enters the conveyor 3 from the upstream conveyor belt, triggering the photoelectric sensor to start the adjustment program. The position adjustment device 4 drives the product to move to the preset coordinates, and the attitude adjustment device 5 detects the tilt of the product and restores it to horizontal by pushing the push rod 513.
[0030] Preferably, such as Figure 2 As shown, the adjustment device includes a front-to-back position adjustment mechanism at both ends of the first slide groove 21 and a left-to-right position adjustment mechanism on both sides of the first slide groove 21. Both the front-to-back position adjustment mechanism and the left-to-right position adjustment mechanism are slidably connected to the base 1. The front-to-back position adjustment mechanism is used to adjust the front-to-back position of the product, and the left-to-right position adjustment mechanism is used to adjust the left-to-right position of the product.
[0031] Furthermore, such as Figure 3 As shown, the front-to-back adjustment mechanism 41 includes two symmetrically arranged cylinder-driven push plates, located at the inlet and outlet sides of the conveyor 322, respectively. The push plate stroke covers the entire X-axis length of the conveyor 322. The left-to-right adjustment mechanism 42 consists of two sets of linear modules arranged parallel to each other on both sides of the conveyor 322. L-shaped push rods 513 are mounted on the module sliders, which can move synchronously or asynchronously along the Y-axis. The front-to-back and left-to-right mechanisms are controlled independently to avoid motion interference. When the product is too long, the left-to-right mechanism can operate on only one side to avoid collision.
[0032] Optionally, the front and rear adjustment mechanism 41 can be detachably replaced with a servo motor driven lead screw mechanism to adapt to different thrust requirements.
[0033] Preferably, the front and rear position adjustment mechanism includes a first pushing component respectively disposed at both ends of the first slide 21, and the base 1 is provided with a second slide 11 at both ends of the first slide 21 along the conveying direction of the conveyor table 3. The first pushing mechanism is slidably connected to the second slide 11 respectively, and the first pushing component can be controlled to move along the first slide 21 by a lead screw.
[0034] Furthermore, the first pushing assembly consists of a first slider, a lifting cylinder, and a push plate. The first slider slides along the second groove 11 (X-axis direction) of the base 1. The lifting cylinder is vertically mounted on the slider, and its piston rod end is connected to the push plate. The working surface of the push plate is covered with a polyurethane buffer layer. In the initial state, the lifting cylinder retracts, and the push plate is raised above the product height. In the adjustment stage, the cylinder extends, and the push plate presses down to contact the side of the product. Subsequently, the first slider pushes the product along the second groove 11. In the reset stage, the push plate is raised, and the slider returns to its original position to avoid obstructing the subsequent product conveying.
[0035] Optionally, the lifting unit can adopt a motor-driven cam mechanism, which controls the lifting trajectory of the push plate through the cam profile to achieve a more complex motion curve.
[0036] Preferably, the first pushing assembly includes a first slider, a lifting unit fixedly connected to the upper end of the first slider, and a first push rod 513 fixedly connected to the output end of the lifting unit. The first slider is slidably connected to the second slide groove 11, and the push rod 513 is connected to a first push plate. When the conveyor 3 needs to transport products, the first slider is controlled to move and drive the first push rod 513 to a suitable position. Then, the lifting unit is controlled to descend, thereby avoiding the conveyor 3 and facilitating the conveyor 3 to receive and deliver products. The lifting unit can be implemented by a combination of a motor and a lead screw, which will not be described in detail here.
[0037] Furthermore, the left and right adjustment mechanism 42 includes: a second pushing assembly; a second slider that slides along the third slide groove 12102 (Y-axis direction); and a second push rod 513 directly welded to the slider, with a wedge-shaped push block installed at its end. The inclined surface design of the push block generates a downward component force when pushing the product, preventing the product from tilting. When the center of the product deviates from the centerline of the conveyor table 3, the pushing assemblies on both sides move inward synchronously, and the push blocks contact the edges of the product on both sides, centering it.
[0038] Preferably, the lifting unit is equipped with a lifting cylinder, which is fixedly connected to the first slider. The output end of the lifting cylinder is fixedly connected to the push rod 513. The lifting cylinder controls the lifting of the first push plate to avoid the conveyor table 3.
[0039] Furthermore, the posture adjustment device 5 includes a high-position adjustment component, in which a slider slides along the fourth slide groove 13 and a rotatable fork is installed at the end of the support rod 512, with the opening direction of the fork matching the edge contour of the product; and a low-position adjustment component, in which a slider slides along the fifth slide groove 14 and a rubber roller is installed at the end of the support rod 512, which drives the product to rotate through friction.
[0040] Preferably, the left and right position adjustment mechanism includes second pushing components respectively disposed on both sides of the first slide groove 21. The base 1 is provided with third slide grooves 12 perpendicular to the first slide groove 21 on both sides of the first slide groove 21. The second pushing components are slidably connected to the third slide grooves 12. The second pushing components on both sides of the first slide groove 21 form a clamping state. The movement of the second pushing components can be controlled by a motor or cylinder to clamp the product on the conveyor table 3 and adjust the position of the product during the clamping process.
[0041] Preferably, the second pusher assembly includes a second slider and a second push rod 513 fixedly connected to the upper end of the second slider. The second slider is slidably connected to the third slide groove 12, and the second push rod 513 is connected to a first push plate.
[0042] Preferably, the posture adjustment device 5 includes two posture adjustment components 51 disposed on one side of the base 1 at different heights. The two posture adjustment components 51 are disposed at different heights to adjust the posture of the product at different positions. The base 1 is provided with a fourth slide groove 13 and a fifth slide groove 14 on one side of the first slide groove 21 and along the direction of the first slide groove 21. The two posture adjustment components 51 are slidably connected to the fourth slide groove 13 and the fifth slide groove 14 respectively.
[0043] Preferably, such as Figure 4 As shown, the posture adjustment assembly 51 includes a third slider 511 and a support rod 512 fixedly connected to one end of the third slider 511. The third slider 511 is slidably connected to the fourth slide groove 13 and the fifth slide groove 14 respectively. The upper end of the support rod 512 is connected to a push rod 513 that spans the conveyor table 3. The push rod 513 is used to correct the posture of the product. The push rod 513 is moved by controlling the movement of the third slider 511 respectively. The push rod 513 pushes the product over to achieve the purpose of posture adjustment.
[0044] Specifically, the working principle and usage process of this utility model are as follows: The conveyor 3 is controlled to extend and retract along the first slide 21 to receive and deliver products. After the product is conveyed to the preset position by the conveyor 3, the posture adjustment device 5 adjusts the posture of the product to make the product in the preset posture. Then, the position adjustment device 4 adjusts the position of the product up, down, left and right to achieve precise adjustment of the product position, especially for the position adjustment of cuboid products, which facilitates the processing of the next process.
[0045] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
