Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, specifically an automatic feeding machine for semi-finished workpieces. Background Technology

[0002] Existing automated production lines typically use automatic feeders for loading workpieces before processing. These feeders usually employ an automatic control unit to drive the conveying unit, which then picks up the workpiece at the end of the conveying unit and performs various processing operations on the semi-finished product. However, due to the feeding position, the head of the semi-finished workpiece is often difficult to be conveyed to the appropriate position for processing, resulting in a significant waste of material. Summary of the Invention

[0003] To address the problem of the difficulty in conveying the head of a semi-finished workpiece to a suitable position, this utility model provides an automatic feeder for semi-finished workpieces.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0005] An automatic workpiece semi-finished product feeder includes a vibratory feeder, an electrical control unit connected to the vibratory feeder, a conveyor belt in front of the vibratory feeder, a clamping and flipping unit above the end of the conveyor belt, a feeding frame below the conveyor belt, and a cutting chamber in front of the conveyor belt. The feeder end of the vibratory feeder is positioned to match the feed end of the conveyor belt. The clamping and flipping unit is movably connected to the side wall of the cutting chamber, and the side wall of the cutting chamber is fixedly connected to the feeding frame. A feed hole is provided in the middle of the side wall of the cutting chamber. A spindle guide rail is installed on the feeding frame. The spindle is driven by a servo motor to move back and forth and is slidably connected to the spindle guide rail. The spindle includes a main body and a spindle gripper at the front end of the main body. The spindle gripper is used to clamp the workpiece semi-finished product.

[0006] Specifically, the clamping and flipping unit includes a feeding gripper cylinder, a flipping cylinder, and a feeding gripper. The feeding gripper is connected to the feeding gripper cylinder via a gripper cylinder connecting plate. The output end of the flipping cylinder is connected to the gripper cylinder. A vertical guide rail is provided on the side of the flipping cylinder.

[0007] Specifically, the clamping and flipping unit is slidably connected to the lifting cylinder via a vertical guide rail; the lifting cylinder is slidably connected to the transverse slide rail via a lifting cylinder connecting plate.

[0008] A further improvement is that a translational electric cylinder slider, driven by a translational electric cylinder, is installed in the middle of the transverse slide rail.

[0009] The clamping and flipping unit can move horizontally and vertically respectively under the drive of the translation electric cylinder and the lifting air cylinder.

[0010] A further improvement is that the number of feeding grippers is four or six, which are connected to the feeding gripper cylinder via a gripper cylinder connecting plate.

[0011] A further improvement is that the feeding gripper cylinder is equipped with a feeding gripper cylinder speed control valve; the tilting cylinder is equipped with a tilting cylinder speed control valve, and the above two speed control valves are used to control the air intake of the above two cylinders.

[0012] Specifically, the main body of the spindle has a mandrel running through its center. The front end of the mandrel is connected to the spindle gripper, and the rear end of the mandrel is connected to the movable frame via a rotating shaft. One side of the movable frame is connected to the spindle cylinder via a rotating shaft. When the spindle cylinder extends, the movable frame drives the mandrel to move backward. At this time, because the inner diameter of the channel where the mandrel is located is small, the spindle gripper retracts towards the center under the action of tension to hold the workpiece semi-finished product.

[0013] The electrical control unit consists of an interconnected control cabinet, a status display screen, and connecting cables, which are connected to the vibratory feeder. All components of the electrical control unit used in this invention are assembled from commercially available products.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This product, through the coordinated movement of the clamping and flipping units and the back-and-forth motion of the spindle, can cut and process the head of a workpiece semi-finished product into a finished product, solving the problem of workpiece material waste and making full use of existing workpiece materials to improve the output rate of the production line.

[0031] The present invention will be further explained and described below with reference to the accompanying drawings and embodiments.

[0032] Example: Figure 1 and Figure 2As shown, an automatic feeding machine for semi-finished workpieces includes a vibratory feeder 2, an electrical control unit 1 connected to the vibratory feeder 2, a conveyor belt 3 in front of the vibratory feeder 2, a clamping and flipping unit 24 above the end of the conveyor belt 3, a feeding frame 23 below the conveyor belt 3, and a cutting chamber 21 in front of the conveyor belt 3. The end of the feeder 17 of the vibratory feeder 2 is matched with the feed end of the conveyor belt 3. The clamping and flipping unit 24 is movably connected to the side wall of the cutting chamber 21, and a feed hole 22 is provided in the middle of the side wall of the cutting chamber 21. The side wall of the cutting chamber 21 and the feeding frame 23 are fixedly connected.

[0033] like Figure 3 As shown, a spindle guide rail 29 is mounted on the feeding frame 23, and the spindle 16 is slidably connected to the spindle guide rail 29. The axis of the spindle 16 corresponds to the position of the feed hole 22. The spindle 16 includes a main body 28 and a spindle gripper 19 at the front end of the main body 28. The spindle gripper 19 is used to hold the workpiece semi-finished product 4. The spindle 16 can be driven by a servo motor 25 to move back and forth along the conveyor belt 3.

[0034] In this embodiment, a straight conveyor belt is used, driven by a stepper motor. Of course, those skilled in the art will understand that conventional transmission devices such as wheel drives can also be used as needed.

[0035] At least one set of position sensors (not shown in the figure) is installed on the side wall of the cutting chamber 21. When the conveyor belt 3 delivers the workpiece semi-finished product 4 to the designated position, the position sensors send a signal to the stepper motor, and the conveyor belt 3 stops moving, preparing for the clamping action of the clamping and flipping unit 24. The position sensors are commercially available products.

[0036] Furthermore, the clamping and flipping unit 24 includes a feeding gripper cylinder 15, a flipping cylinder 5, and a feeding gripper 20. The feeding gripper 20 is connected to the feeding gripper cylinder 15 through a gripper cylinder connecting plate 14. The output end of the flipping cylinder 5 is connected to the gripper cylinder 15, and a vertical guide rail 26 is provided on the side of the flipping cylinder 5.

[0037] Furthermore, the clamping and flipping unit 24 is slidably connected to the lifting cylinder 9 via the vertical guide rail 26; the lifting cylinder 9 is slidably connected to the transverse slide rail 18 via the lifting cylinder connecting plate 12. A translation electric cylinder slider 11 driven by the translation electric cylinder 10 is installed in the middle of the transverse slide rail 18.

[0038] The clamping and flipping unit 24 can move horizontally and vertically in the plane of the side wall of the cutting chamber 21 under the drive of the translation electric cylinder 10 and the lifting cylinder 9.

[0039] The feed hole 22 is circular. Of course, depending on the processing requirements, the shape of the feed hole 22 can also be designed into other common shapes such as square, based on the shape of the spindle jaw 19.

[0040] like Figure 8 As shown, the main shaft 16 is located inside the conveyor belt 3. A mandrel 27 runs through the middle of the main body 28 of the main shaft. The front end of the mandrel 27 is connected to the main shaft gripper 19, and the rear end of the mandrel 27 is connected to the movable frame 31 via a rotating shaft. One side of the movable frame 31 is connected to the main shaft cylinder 30 via a rotating shaft. During operation, the main shaft gripper 19 can hold the workpiece semi-finished product 4 that has reached the front of the feed hole 22, and then move with the front part of the main shaft 16 into the cutting chamber 21 to prepare for the cutting operation.

[0041] like Figure 3 and Figure 4 As shown, the lifting cylinder 9 is equipped with a lifting cylinder speed control valve 8, the feeding gripper cylinder 15 is equipped with a gripper cylinder speed control valve 13, and the tilting cylinder 5 is equipped with a tilting cylinder speed control valve 6. The above three speed control valves are used to control the air intake of the above three cylinders, affecting the effect of cylinder action, and realizing flexible control of the position of the workpiece semi-finished product 4.

[0042] Please see Figure 2 The cutting of the workpiece semi-finished product 4 is completed in the cutting chamber 21. In this embodiment, a sliding headstock CNC machine tool is used to complete the cutting process. In the cutting chamber 21, the workpiece semi-finished product 4 can also be subjected to machining operations such as directional milling or tapping.

[0043] like Figure 5 As shown, the clamping and flipping unit 24 includes four or six feeding jaws 20 evenly distributed on the same plane, which are all connected to the feeding jaw cylinder 15 through the jaw cylinder connecting plate 14.

[0044] The structure of the electrical control unit 1 is based on existing technology and mainly includes interconnected control cabinets, status display screens, and cables (not shown) connected to the vibratory feeder 2. Of course, to complete the feeding operation, the vibratory feeder 2 is not particularly limited to feeding; those skilled in the art can also use other feeding devices depending on the shape of the workpiece semi-finished product.

[0045] The specific working process of this embodiment is as follows: First, as shown in the example... Figure 1 As shown, driven by the electrical control unit 1, the semi-finished workpiece 4 (hereinafter referred to as "workpiece") is conveyed from bottom to top by the vibratory feeder 2, and then conveyed to the conveyor belt 3 by the feeder 17. The conveyor belt 3 then transports the workpiece to the end of the conveyor belt 3. Figure 4 As shown, when the automatic feeder receives the workpiece arrival signal, the tilting cylinder 5 actuates, tilting downwards 90° counterclockwise; then as... Figure 5 As shown, the lifting cylinder 10 descends, and after reaching the lower position, the feeding gripper cylinder 15 actuates to clamp the workpiece; then as... Figure 6As shown, the lifting cylinder 9 rises, and simultaneously, the tilting cylinder 5 actuates, rotating 90° clockwise upwards; then... Figure 7 As shown, the translational electric cylinder 10 actuates, causing the clamping and flipping unit 24 to reach above the feed hole 22; then as... Figure 8 As shown, the lifting cylinder 9 lowers the workpiece to the feed hole 22 position, and the main shaft 16 moves along the conveyor belt 3 to the workpiece position; then as... Figure 9 As shown, the spindle cylinder 30 extends, the spindle jaws 19 grip the head of the workpiece, and then the feed jaws 20 release; next as... Figure 10 As shown, the electrical control unit 1 drives the spindle 16 to move backward and return to its original position; next as... Figure 11 As shown, the lifting cylinder 9 rises again, as... Figure 12 The translational electric cylinder 10 drives the clamping and tilting unit 24 away from the feed hole 22; finally, as shown... Figure 13 As shown, the spindle 16, driven by the servo motor 25, pulls the workpiece into the cutting chamber 21, where the cutting process is completed using a Swiss-type CNC machine tool. This process can then be repeated to sequentially feed and process several workpieces arranged on the conveyor belt.

[0046] Figure 14 The shapes of the main components of the conveyor belt 3 and the clamping and flipping unit 24 in this embodiment are shown, which helps those skilled in the art to better understand the product of this utility model.

[0047] This utility model achieves full utilization of workpiece raw materials through automatic control of the mechanical structure, improves the yield rate on the production line, and effectively solves the technical problem of difficult processing of the four heads of semi-finished workpieces, thus achieving the technical effect of making the best use of materials.

[0048] Furthermore, it will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, which are clearly only a part of the embodiments, not all of them. Moreover, this utility model can be implemented in other specific forms without departing from its spirit or essential characteristics. That is to say, those skilled in the art can obtain new embodiments by modifying, altering, or combining these embodiments without creative effort. Therefore, the embodiments should be considered exemplary rather than restrictive in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing explanations and descriptions. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within this utility model. It should also be clearly understood that no reference numerals in the claims should be construed as limiting the scope of the claims.
