DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 In this embodiment, a hole-opening device for metal castings includes an operating table 1 and a rotating disk 2 installed at the center of the operating table 1, six inclined molds 3 are installed on the side of the top of the rotating disk 2, and the molds 3 are provided with placement grooves adapted to the products. A loading component 4, a hole-opening component 5 installed on the left side of the rotating disk 2, and a unloading component installed on the right side of the rotating disk 2 are installed on the table surface of the operating table 1.

[0021] In the above structure, the mold can be driven to pass through the loading component, the hole-opening component and the unloading component in sequence through the progressive rotation of the rotating disk, thereby forming a set of production lines. Under the action of the loading component, the product can be placed in the placement slot of the mold according to the position of the mold, realizing the automatic loading operation. At the same time, the hole-opening component can press down the product to position it while opening the hole, which can prevent the deviation from affecting the drilling during the opening. Then, through the unloading component, the product can be automatically unloaded, thereby reducing manual intervention and realizing automated production. Therefore, it can improve output and production efficiency and avoid deviations.

[0022] like Figure 2-3In the direction shown, the loading assembly 4 includes a vertical plate 401 fixed on the operating table 1, a propulsion cylinder 402 is installed on the top of the left side of the vertical plate 401, a moving block 403 is fixed to the ejection end of the propulsion cylinder 402 and is slidably connected to the front of the vertical plate 401, a lifting cylinder 404 is installed on the back of the moving block 403, a lifting plate 405 is fixed to the ejection end of the lifting cylinder 404 and is slidably connected to the front of the moving block 403, a rotating part is installed on the front of the lifting plate 405, and a clamping cylinder 412 is installed on the rotating end of the rotating part. The lifting cylinder can drive the clamping cylinder to move up and down through the lifting plate, so as to realize the operation of picking up and discharging. Under the operation of picking up and discharging, the moving block can be pushed by the propulsion cylinder to drive the clamping cylinder to move above the picking up and discharging. At the same time, when it is located above the picking up and discharging, the clamping cylinder can be driven to rotate through the rotating part to adjust the direction of the product, so as to adapt the picking up and placing products.

[0023] Among them, the rotating part includes a guide block 407 fixed on the front of the lifting plate 405, a convex-shaped slide groove is opened on the front of the guide block 407, a forward push cylinder 406 is installed on the left side of the guide block 407, and a rotating shaft 411 is installed inside, the clamping cylinder 412 is installed at the bottom of the rotating shaft 411, and a stopper 408 is fixed on the front of the guide block 407 to block the half of the convex-shaped slide groove, a gear 410 extending to the inside of the convex-shaped slide groove is fixed on the outer side of the rotating shaft 411, and a rack 409 sliding with the guide block 407 and meshing with the gear 410 is fixed at the ejection end of the forward push cylinder 406. When the rack is driven forward by the forward push cylinder, the convex slide groove plays a guiding and limiting role. At the same time, under the action of the stop block, it can limit the rack to move out. Then, through the meshing rotation shaft of the rack and the gear, it can drive the clamping cylinder to rotate and change the clamping direction of the clamping end of the clamping cylinder. Therefore, the direction can be adjusted according to the material picking and discharging.

[0024] like Figure 4 In the direction shown, the hole-opening assembly 5 includes a support plate 501 fixed on the operating table 1, an ejection cylinder 502 is installed on the upper part of the front of the support plate 501, and a top plate 503 fixedly connected to the ejection end of the ejection cylinder 502 is slidably connected to the back of the support plate 501. The top plate 503 is T-shaped, and a push-down cylinder 504 is installed on the top left side of the top plate 503. The ejection end of the push-down cylinder 504 is fixed with a push plate 505 slidably connected to the top plate 503, and a drill bit 508 and a clamping part are installed on the plate surface of the push plate 505. First, when the ejection cylinder drives the top plate to move, the position of the drill bit can be adjusted so that the drill bit can be adjusted to a suitable position above the product. When the push plate is driven downward by the push-down cylinder, during the downward movement, the clamping part can first press down and tighten the product, and then continue to press down, and the drill bit completes the hole-opening operation on the product, so that automatic drilling and product displacement when placing the drilling can be realized.

[0025] The clamping part includes a buffer assembly fixed on the push plate 505, a pressure block 507 is fixed at the bottom of the buffer assembly, the buffer assembly is a damper 506, the pressure block 507 is fixed on the top rod of the damper 506, the top of the pressure block 507 is L-shaped, and the bottom is concave. When the push plate moves down, the pressure block will first contact the product, press down through the bottom of the concave shape, and at the same time, it will push the top rod into the damper, thereby playing a buffering role. At the same time, while pressing the product, the push plate continues to move down so that the drill bit can open the hole stably and the placement is offset.

[0026] like Figure 1 In the direction shown, the unloading assembly includes a transplanting device 9 installed on the operating table 1 and located on the right side of the rotating disk, and a frame 6 located below the transplanting device 9. A screw device 7 is installed on the frame 6. The movable end of the screw device 7 is fixed with a slot plate slidably connected to the frame 6, and a tray 8 is placed on the top of the slot plate. The processed products can be transferred to the tray for placement through the transplanting device, and the screw device cooperates with the transplanting device to move the tray to receive the products.

[0027] Among them, the top of the operating table 1 is located on the right side behind the rotating disk and a fixed plate 10 is installed. The front of the fixed plate 10 is installed with a lower push cylinder 11. The ejection end of the lower push cylinder 11 is fixed with a lifting plate 12. The top of the lifting plate 12 is installed with a side push cylinder 13. The ejection end of the side push cylinder 13 is installed with a blowing device 14. An L-shaped groove is opened on the left side of the front of the lifting plate 12, and the blowing end of the blowing device 14 is located in the L-shaped groove. The lifting plate is driven by the lower push cylinder to move, so that the distance between the blowing device and the mold can be adjusted. The side push cylinder drives the blowing device to move in the L-shaped groove. The L-shaped groove plays a limiting role, so that the blowing device can complete the blowing in the supporting area, so that the waste and impurities generated by the opening in the mold can be cleaned up to avoid affecting the next group of openings.

[0028] The working principle of the above embodiment is:

[0029] First, the lifting cylinder drives the lifting plate to move, which can drive the clamping cylinder above the material taking and move up and down to complete the material taking operation. After taking the material, the pushing cylinder drives the moving block to be ejected, so that the clamping cylinder is located above the mold, and then the forward pushing cylinder drives the gear to rotate through the rack, so that the rotating shaft rotates, which can drive the clamping cylinder to rotate, so that the direction of the product matches the placement slot above the mold, and the lifting cylinder drives the clamping cylinder close to the mold to complete the loading operation. After placement, when the rotating disk rotates, the product is located below the drill bit, and the ejection cylinder drives the top plate to move, which can adjust the position of the drill bit and the pressure block above the product to achieve the function of adjusting the position. After determining the position, the downward pushing cylinder drives The push plate moves downward, the pressure block first contacts the product and presses down, and the pressure block pushes the damper upward, and the damper acts as a buffer. The push plate continues to move downward until the drill bit completes the hole in the product. Therefore, the pressure block can improve the stability of the hole and avoid the hole deviation. Then the product is transferred to the tray through the transplanting device for collection. During the collection process, the screw device will drive the tray to move, so that the tray moves with the transplanting device, thereby realizing the function of automatic unloading. Finally, the lifting plate is driven downward by the lower cylinder to bring the blowing device close to the mold, and the mold placement groove is blown up by the blowing device. Then the blowing device is driven to move by the side push cylinder to complete the cleaning of the waste chips in the mold.

[0030] Therefore, the above-mentioned production line capable of realizing automatic hole opening can independently complete loading and unloading, hole opening and cleaning, thereby effectively improving output and production efficiency, as well as hole opening stability.
