Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing technology for tubular and shell-type workpieces, and in particular to a workpiece removal device. Background Technology
[0002] After communication-related tubular components are machined using CNC machine tools, a worker is often required to clamp and unclamp the workpiece after the external structure is completed. This method is obviously inefficient. Therefore, automated loading, clamping, and unloading methods are now used to improve machining efficiency. To achieve automated unloading, machine tool fixtures are often used to automatically release the clamps. A suction tube is installed at one end of the fixture, and a holding box is installed at the other end. A suction pipe is connected to the holding box, which is connected to a vacuum pump. The negative pressure inside the holding box draws the machined workpiece into the holding box. While this method can basically achieve automated unloading, it requires sufficient suction, resulting in a high workload on the vacuum pump, and workpieces tend to accumulate in one spot in the holding box. Utility Model Content
[0003] This utility model provides a part-retrieving device to overcome the shortcomings of the prior art, and solves the problems of large working load of vacuum devices and easy accumulation of workpieces, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0005] A part-receiving device includes a base with two pairs of L-shaped plates mounted on it by screws. The L-shaped plates have a movable base inside them. The movable base has a rectangular structure, and a holding box is placed on the movable base. The holding box has a rectangular structure and is used for receiving and stacking workpieces.
[0006] The upper ends of the opposite side walls of the holding box are provided with U-shaped grooves, and pipes are provided in the U-shaped grooves. The inner end of the pipe is open downward to form a discharge port. The pipes are used to guide and limit the movement of the workpiece into the holding box, so that the workpiece can move to the discharge port and fall into the holding box.
[0007] A cylinder mounting base is installed on the base by screws. A cylinder is fixed to the upper end of the cylinder mounting base. A suction head is installed on the movable end of the cylinder. A suction tube is connected to the suction head. The suction head is inserted into the tube. The workpiece is transferred by sucking up the workpiece by the suction head, which reduces the problem of the large load of the existing vacuum device. The cylinder can pull the suction head and the workpiece adsorbed on the suction head to the discharge port, thereby facilitating the workpiece discharge operation.
[0008] Furthermore, limit plates are installed on the four side walls of the movable base by screws. The limit plates are used to limit the position of the container, and the limit plates play a role in limiting the position of the four side walls of the container.
[0009] Furthermore, a pair of vertical holes are provided on the L-shaped plate, and a limiting screw passes through the vertical holes. The inner end of the limiting screw is threaded to the movable base. A limiting upper plate is inserted into the upper end of the L-shaped plate, which supports the movable base. The limiting screws and vertical holes facilitate the movement of the movable base. When the movable base moves to the upper end of the vertical holes, it can be fixed by the limiting upper plate to lock the height of the container. In addition, the movable base facilitates the insertion of pipe fittings into the U-shaped groove.
[0010] Furthermore, the upper end of the L-shaped plate is formed with a protruding plate, and a pin is inserted into the protruding plate. The lower end of the pin is fitted with an outer sleeve, which is welded to the outer end of the upper limiting plate. The upper limiting plate can be locked by the provided pin to ensure the stability of the upper limiting plate when locked.
[0011] Furthermore, a pair of U-shaped rings are fitted onto the pipe fitting. One end of the U-shaped ring is formed with an inclined plate. The inclined plate is located directly below the discharge port, and the lower end of the inclined plate abuts against the bottom of the holding box, so that the inclined plate is tilted. When the workpiece is unloaded, the inclined plate guides the workpiece to prevent the workpiece from piling up in the holding box.
[0012] Furthermore, an upper extension seat is installed on the base by screws, and a guide rail is installed on the upper end of the upper extension seat by screws. A pair of clamps are slidably arranged on the guide rail. The inner wall of the clamps is provided with an arc groove, and the inner wall of the arc groove is in close contact with the outer periphery of the pipe. The clamps can constrain the pipe.
[0013] Furthermore, to ensure the limiting effect of the clamping plate on the pipe fitting, a vertical plate is installed on the outside of the guide rail by screws. A pair of strip holes are opened on the vertical plate, and a connecting screw passes through the strip holes. The inner end of the connecting screw is connected to an inner plate by threads. A concave part is provided on the inner plate. The lower end of the vertical section of the concave part has an inner pressure block formed on its inner wall. A pair of convex plates are provided on the outer wall of the clamping plate. The outer wall of the convex plate has a slope formed on its outer wall. The upper end of the slope extends inward at an incline. The inner wall of the inner pressure block has a sloped wall formed on its inner wall. The sloped wall acts on the sloped surface.
[0014] Furthermore, in order to facilitate the movement of the clamping plate toward the pipe fitting and to constrain and fix the pipe fitting through the clamping plate, a hinge screw is threadedly connected to the vertical plate, and a lower top plate is rotatably provided on the hinge screw. The lower end of the lower top plate acts on the horizontal section of the concave part.
[0015] The advantages of the above technical solution are:
[0016] This invention uses a suction head to pick up the workpiece and a cylinder to move it to the discharge port, thus facilitating workpiece unloading. Furthermore, it prevents workpieces from piling up in one location within the holding box. Attached Figure Description
[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.
[0018] Figure 1 A three-dimensional structural diagram of one embodiment is shown.
[0019] Figure 2 A magnified view of point A is shown.
[0020] Figure 3 A three-dimensional structural diagram of the pipe fitting constraint mechanism is shown. Detailed Implementation
[0021] like Figures 1-3 As shown, a retrieval device includes a base 1, on which two pairs of L-shaped plates 2 are mounted by screws. A movable base 21 is provided inside the L-shaped plates 2. The movable base 21 has a rectangular structure, and a holding box 3 is placed on the movable base 21. The holding box 3 has a rectangular structure.
[0022] Limiting side plates 26 are installed on the four side walls of the movable base 21 by screws. The limiting side plates 26 are used to limit the placement of the container 3. A pair of vertical holes 20 are opened on the L-shaped plate 2. Limiting screws 22 are inserted into the vertical holes 20. The inner end of the limiting screws 22 is connected to the movable base 21 by threads. A limiting upper plate is inserted into the upper end of the L-shaped plate 2. The limiting upper plate is used to support the movable base 21. A protruding plate 23 is formed on the upper end of the L-shaped plate 2. A pin 24 is inserted into the protruding plate 23. An outer sleeve 25 is fitted onto the lower end of the pin 24. The outer sleeve 25 is welded to the outer end of the limiting upper plate.
[0023] The upper ends of the opposite side walls of the container 3 are provided with U-shaped grooves 30, and pipe fittings 5 are provided in the U-shaped grooves 30. The inner end of the pipe fittings 5 is open downward to form a discharge port 63.
[0024] A cylinder mounting base 4 is installed on the base 1 by screws. A cylinder 40 is fixed to the upper end of the cylinder mounting base 4. A suction head 41 is installed on the movable end of the cylinder 40. A suction tube is connected to the suction head 41 and the suction head 41 passes through the tube 5.
[0025] In this embodiment, when unloading the workpiece, the holding box 3 is placed first, and then the workpiece is unloaded.
[0026] When placing the container 3, the movable base 21 is located at the lower end of the L-shaped plate 2. Then, the container 3 is placed on the movable base 21. After placement, the container 3 is moved upward so that the limiting screw 22 moves to the upper end of the vertical hole 20. Then, the limiting upper plate is pushed inward in sequence, and the lower end of the movable base 21 is supported by the limiting upper plate. Then, the pin 24 is inserted into the outer sleeve 25. At this time, the pipe 5 will also be located in the U-shaped groove 30.
[0027] When unloading the workpiece, cylinder 40 is activated, and the vacuum device is also activated to generate suction in the suction head 41. Cylinder 40 also moves the suction head 41 toward the workpiece, and the workpiece is adsorbed by the suction head 41. Then, cylinder 40 pulls the adsorbed workpiece inside the tube 5 toward the discharge port 63. When it moves to the discharge port 63, the suction generated by the vacuum device disappears, and the workpiece falls downward through the discharge port 63.
[0028] In some embodiments, a pair of U-shaped rings 64 are fitted onto the pipe 5. One end of the U-shaped ring 64 is formed with an inclined plate 65. The inclined plate 65 is located directly below the discharge port 63. The lower end of the inclined plate 65 abuts against the bottom of the container 3 so that the inclined plate 65 is in an inclined position.
[0029] During the unloading process, as the workpiece moves downward from the discharge port, it will roll down the slope of the inclined plate 65 into the holding box 3. If a large number of workpieces accumulate at one end of the holding box 3, the inclined plate 65 is then tilted in the other direction, and the workpiece unloading operation continues.
[0030] In some embodiments, an upper extension seat 50 is mounted on the base 1 by screws, and a guide rail 51 is mounted on the upper end of the upper extension seat 50 by screws. A pair of clamping plates 52 are slidably mounted on the guide rail 51. An arc groove 53 is formed on the inner wall of the clamping plate 52, and the inner wall of the arc groove 53 is in close contact with the outer periphery of the pipe 5. A vertical plate 570 is mounted on the outer side of the guide rail 51 by screws. A pair of strip holes 56 are formed on the vertical plate 570. A connecting screw 58 passes through the strip holes 56. The inner end of the connecting screw 58 is threaded to an inner plate 57. A concave part 61 is provided on the inner wall of the lower end of the vertical section of the concave part 61. An inner pressure block 62 is formed on the inner wall of the clamping plate 52. A pair of convex plates 55 are provided on the outer wall of the convex plate 55. An inclined surface is formed on the outer wall of the convex plate 55. The upper end of the inclined surface extends inward at an incline. An inclined wall is formed on the inner wall of the inner pressure block 62. The inclined wall acts on the inclined surface. A hinge screw 59 is threadedly connected to the vertical plate 570. A lower top plate 60 is rotatably mounted on the hinge screw 59. The lower end of the lower top plate 60 acts on the horizontal section of the concave member 61.
[0031] In this embodiment, when fixing the pipe fitting 5, the operator rotates the lower top plate 60. As the lower top plate 60 rotates, the concave part 61 moves downward. When the concave part 61 moves downward, the inclined wall of the inner pressure block 62 at its lower end acts on the inclined surface, thereby causing the clamping plate 52 to move towards the outer periphery of the pipe fitting 5, and fixing the pipe fitting 5 through the clamping plate 52. This fixing method facilitates the adjustment of the elongation length of the pipe fitting 5.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
