Description

Technical Field

[0001] The invention relates to the technical field of automatic feeding in numerically controlled machine tool processing, in particular to a lathe feeding device used in numerically controlled machine tool processing. Background Art

[0002] CNC Swiss-type lathes are a type of CNC lathes. Traditional CNC lathes are mainly in tool-feeding mode, which is called tool-feeding machines. The product is clamped at a fixed position and processed by the rotation of the spindle and the movement of the tool. However, Swiss-type lathes have tools at fixed positions and process products by the movement and rotation of the spindle, which supports multiple feeding.

[0003] Therefore, compared with the knife-feeding machine tools, when the Swiss-type lathe is turning, the bar is axially fed through the center guide sleeve, and the tool cutting point is close to the guide sleeve mouth end, which has good rigidity, eliminates the deformation of the bar under the cutting pressure of the tool, ensures the accuracy of the parts, and has an absolute advantage in processing slender shaft parts; but the Swiss-type lathe normally only supports batch processing of long bars; it cannot process short materials in single pieces like the knife-feeding machine; at the same time, because the bar needs to pass through the entire spindle, chuck, and guide sleeve, the Swiss-type lathe has higher requirements for the straightness and ovality of the raw materials. Usually, a feeding mechanism is equipped when processing bar materials on the Swiss-type lathe, and the bar materials need to be provided. Calibration and placement are performed before loading, that is, material processing before loading, including correction of material placement direction and alignment of materials to ensure the same processing position. When the feeding mechanism actively discharges materials, it is easy to discharge multiple groups of bars at the same time, causing the feeding mechanism to be blocked, which in turn triggers the loading alarm of the CNC machine tool, increases the number of shutdowns for maintenance, and reduces the processing efficiency of the lathe. Secondly, most turning and milling composite processing equipment has the function of online detection, which can realize the in-situ detection and precision control of key data in the manufacturing process, that is, scanning first and then processing, thereby improving the processing accuracy of the product, but it will lead to a decrease in the overall processing rate;

[0004] Therefore, we propose a lathe feeding device for CNC machine tool processing. Summary of the invention

[0005] The object of the present invention is to provide a lathe feeding device for CNC machine tool processing, so as to solve the problem that when the feeding mechanism installed on the CNC machine tool is actively discharging materials, it is easy to discharge multiple groups of bar materials at the same time, causing the feeding mechanism to be blocked, thereby triggering the CNC machine tool feeding alarm, and at the same time, the machine tool feeding mechanism lacks active material analysis, and the production efficiency cannot be further improved;

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A lathe feeding device for CNC machine tool processing, comprising a frame, a machine tool material locking integration, a cylinder and a material transfer box, wherein the frame is equipped with a machine tool material locking integration, the frame is equipped with a cylinder at one side of the machine tool material locking integration, a material transfer box is fixed by bolts at one side of the frame and at the end of the cylinder, a sliding box is fixed by bolts at one side of the material transfer box, and a docking box is installed on the sliding box;

[0008] The inner wall of the material transfer box is movably connected with a rotating shaft, and a cam 2 is sleeved and fixed on the outer wall of the rotating shaft. A sleeve rod is slidably connected to the inner wall of the material transfer box, and a lifting block is slidably sleeved on the sleeve rod. A pad is fixed to the bottom side of the lifting block by spot welding, and the pad is in contact with the outer wall of the cam 2. Limiting grooves are evenly arranged on the lifting block, and side frames are fixed to the inner walls on both sides of the material transfer box by bolts.

[0009] Furthermore, a feed port is provided on one side of the top of the material transfer box, a lifting plate is slidably connected to the discharge side of the material transfer box, a cam is fixedly mounted on the rotating shaft, and one side of the lifting plate passes through the inner wall of the material transfer box and abuts against the outer wall of the cam.

[0010] Furthermore, a turntable is sleeved and fixed in the material transfer box and located on one side of cam one, one end of the sleeve rod passes through the inner wall of the material transfer box and is fixed with a roller by bolts, and a spring is sleeved and installed on the other side of the sleeve rod and located on the inner wall of the material transfer box, and one side of the roller is in contact with the outer wall of the turntable.

[0011] Furthermore, a rolling cavity is provided in the sliding material box, a stopper is symmetrically fixed on the outlet side of the rolling cavity and located on the outer wall of the sliding material box by spot welding, and a CCD camera is fixed on the sliding material box and located on the inner wall of the rolling cavity by bolts.

[0012] Furthermore, a trough block is movably connected to the sliding box and located on one side of the docking box. The trough block is slidably connected to a material receiving shell in the rolling cavity. One side of the material receiving shell is symmetrically fixed with protrusions by spot welding, and the protrusions are clamped with holes on the trough block. A material receiving box is installed at the bottom of the sliding box.

[0013] Furthermore, a push column is slidably connected in the material receiving shell, a placement plate is slidably connected in the docking box, an electric push rod is fixed to the inner wall of the docking box by bolts, one end of the electric push rod is fixed to the placement plate, and one end of the push column passes through one side of the docking box and is movably connected to the placement plate through a bearing.

[0014] The lathe feeding method used for CNC machine tool processing is:

[0015] Use the cylinder to push the loading outlet side of the sliding material box to align with the integrated feeding port of the machine tool, then put the bars to be processed into the feeding port of the material transfer box, start the motor on the material transfer box, and drive the rotating shaft in the material transfer box to rotate;

[0016] The rotation of the rotating shaft realizes the rotation of cam 1, which drives the lifting plate to rise. When it reaches the top of one side of the material transfer box, the bar automatically falls along the inclined surface of the lifting plate to the limiting groove on the surface of the lifting block. With the continuous rotation of the rotating shaft, cam 2 on the rotating shaft begins to contact the bottom pad of the lifting block, driving the lifting block to rise. At the same time, the inclined surface of the rotating disk contacts the sleeve rod, so that the entire lifting block slides on the inside of the side frame. Then the lowered lifting block places the received bar on the side frame, and with the subsequent rotation of the rotating shaft, the material moving and placing operations on the side frame are repeated until the front end bar is sent to the side of the stopper;

[0017] The intercepted bars enter the sliding box and are dynamically photographed by the CCD camera while rolling in the rolling cavity. The photographs are then transmitted to an external computer for identification of the bar placement direction and surface defects. When the bars fall onto the receiving shell, the bar decision signal is output. The qualified bars are moved by the electric push rod and pushed into the machine tool locking assembly, and processed in cooperation with the cutting table on the other side of the frame. The unqualified bars are rotated 180° by the rotation of the swivel block, and the receiving shell is automatically dropped into the receiving box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the motor drives the rotating shaft in the material transfer box to rotate, so that the rotary disk, cam one and cam two rotate at the same time, and after the cam one rotates, the entire lifting plate is pushed up and down, so that the bars stored in the material transfer box are pushed onto the lifting block one by one, and then the cam two drives the pad to move and the rotary disk squeezes the sleeve rod to realize the lifting block to move between the side frames, complete the fixed frame movement of the bars, and finally push the single bar into the rolling cavity. Only the continuous rotation of the rotating shaft is required to complete the continuous addition of bars in the sliding material box, and at the same time, it is avoided that multiple bars are discharged in a concentrated manner, causing the material feeding blockage, causing the CNC machine tool to report an error, and affecting the subsequent processing efficiency of the entire bar;

[0020] 2. In the present invention, the bars are dropped one by one along the rolling cavity onto the receiving shell, and the CCD camera is used to take rolling pictures of the bars, and the surface morphology and placement direction information of the bars are fed back in time. Subsequently, the controller is used to realize the rotation of the trough block located on the surface of the slide box, thereby driving the receiving shell connected to the push pin to rotate, and the defective surface bars are discharged into the receiving box in time, rather than being directly pushed into the machine tool to lock the material for subsequent bar processing. The defective rate of the bar processing products caused by the material itself after the bars are processed by the CNC machine tool is reduced, and detection is performed at the source. At the same time, high-speed feeding will not affect the subsequent bar processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-6 , the present invention provides a technical solution:

[0030] Embodiment 1: The CNC machine tool is later equipped with an adaptive automatic feeding mechanism to improve the turning and milling efficiency of the parts. Figure 1 As shown, a height-adjustable material transfer box 4 is installed in the original frame 1 to realize the central axis positioning of the bar material and the machine tool locking material integration 2, and complete the precise docking of the bar material. Secondly, the sliding box 18 installed on the side of the material transfer box 4 monitors the bar material in the rolling process to ensure that the direction of the bar material pushed into the machine tool locking material integration 2 is correct and there are no defects on the surface of the bar material, so as to realize material screening during feeding;

[0031] The feed inlet 5 on one side of the material transfer box 4 is located outside the frame 1, and the bars to be processed are usually directly put in, and the lifting plate 10 on the outlet side of the material transfer box 4 is abutted and cannot discharge the materials normally, so the lifting plate 10 needs to be movable, such as Figure 3 As shown, a rotating shaft 6 is movably connected in the material transfer box 4, and a cam 1 8 and a cam 2 9 are fixedly mounted on the rotating shaft 6. The cam 1 8 is opposite to the protruding side of the cam 2 9, and is located on one side of the lifting plate 10 at the top of the material transfer box 4 and abuts against the surface of the cam 1 8. With the rotation of the rotating shaft 6, the cam 1 8 rotates to realize the telescopic movement on the lifting plate 10. When the lifting plate 10 moves down to the lowest side, a single bar material comes between the inclined surface of the lifting plate 10 and the vertical surface of the material transfer box 4, and then the single bar material is pushed to the limiting groove 13 of the lifting block 12 for storage during the rising process of the lifting plate 10.

[0032] Combination Figure 2 As shown, the top of the cam 29 on the rotating shaft 6 abuts against the pad 17, and the top of the pad 17 is installed with the lifting block 12, and the middle shaft connected to the lifting block 12 passes through the sleeve rod 14 and is slidably connected to the sleeve rod 14, and the rotation of the rotating shaft 6 realizes that the middle shaft of the lifting block 12 moves up and down on the surface of the sleeve rod 14, which also drives the bar material to move alternately between the lifting block 12 and the side frame 11. As for the installation of the sleeve rod 14 in the material transfer box 4, it can slide left and right in the material transfer box 4, and reset by squeezing the sleeve spring 16 when moving to the right, and one end of the sleeve rod 14 passes through the inner wall of the material transfer box 4 and is installed with a roller The roller 15 is in contact with the outer periphery of the rotating disk 7 fixed on the rotating shaft 6. The rotating disk 7 is convex and will push the entire sleeve rod 14 to move rightward when it rotates, thereby driving the entire lifting block 12 to move rightward. With the continuous rotation of the rotating shaft 6, the lifting block 12 will move downward and backward due to the left push of the spring 16 and the rotation of the cam 29. That is, the rotation of the entire rotating shaft 6 first realizes the upper right movement and lower left reset of the lifting block 12, and realizes the pushing of the rod to move a certain distance on the side frame 11. Finally, the rod at the front is sent to the side block 20 of the sliding box 18 by the lifting block 12;

[0033] like Figure 4 As shown, a rolling cavity 21 is opened on the side of the stopper 20 of the sliding material box 18, and the rolling cavity 21 extends all the way to the bottom of the sliding material box 18. Figure 6 It can be seen that the bottom of the slide box 18 is connected with a receiving box 29 for receiving the rods after partial inspection. The rods that meet the standards fall onto the receiving shell 23 and are finally pushed into the machine tool locking assembly 2. With the clamping rotation of the rods by the machine tool locking assembly 2 and the contact of the tool, the milling operation begins. The combined movement of the lifting plate 10 and the lifting block 12 is realized through the rotation of the rotating shaft 6, so that the single rod is continuously moved into the slide box 18 for pushing, avoiding the combined movement of multiple rods and affecting the feeding work of the machine tool locking mechanism.

[0034] Taking into account the different sizes of bars in different batches, the positions of the relevant components of the material transfer box 4 and the sliding box 18 are optimized and adjusted during automatic loading, including the installation of the side frame 11 and the spacing control of the block 20, so as to ensure that bars with small size differences can be automatically loaded. The linkage control of multiple groups of components can be achieved by rotating a single rotating shaft 6, and the bars can be sorted and conveyed one by one, avoiding the problem of multiple bars blocking the machine tool locking integration 2, thereby improving the overall processing efficiency of subsequent bars.

[0035] Embodiment 2: Most turning and milling composite processing equipment has the function of online detection, which can realize online detection and precision control of key data in the manufacturing process, thereby improving the processing accuracy of the product, but it will lead to a decrease in the overall processing rate. For this reason, a detection mechanism is installed on the same side of the automatic feeding mechanism to scan the bar material in advance, so that bar material analysis and defective product processing can be carried out while feeding;

[0036] For this purpose, a docking box 19 is installed on one side of the slide box 18, and the docking box 19 covers the swivel block 28 on one side of the slide box 18. At the same time, an electric push rod 26 is installed in the entire docking box 19. Figure 5 As shown, a placement plate 27 is fixed to the end of the electric push rod 26, and a push column 25 is movably connected to the same side of the placement plate 27. According to the embodiment 1, the receiving shell 23 is located in the rolling cavity 21, and a protrusion 24 is symmetrically provided on one side of the receiving shell 23. The protrusion 24 is engaged with the hole on the rotating groove block 28, and the entire rotating groove block 28 is located in the docking box 19 and is sleeved with a gear sleeve. It can rotate automatically with the power mechanism, thereby driving the engaged receiving shell 23 to rotate;

[0037] One end of the entire push column 25 passes through one side of the receiving shell 23 and is slidably connected to the receiving shell 23. Therefore, after the receiving shell 23 rotates, the push column 25 will also rotate, and the electric push rod 26 adjusts the position of the placement plate 27, so that the push column 25 can slide freely in the receiving shell 23, thereby pushing out the rods received in the receiving shell 23, and realizing the automatic loading of the rods required by the machine tool locking integration 2;

[0038] The rods falling from the top of the rolling chamber 21 will be photographed at high speed by the installed CCD camera 22 during the rolling process, so that the collected rod images are sent to the external computer. After the storage direction and surface defects of the rods are identified, it is determined whether the rods in the falling process meet the processing mark. When the identified rods are unqualified, the control power mechanism drives the rotating groove block 28 to rotate, and the rotation angle is controlled at 180°. Then the rods placed on the receiving shell 23 automatically fall into the receiving box 29 set at the bottom of the rolling chamber 21. The operator needs to disassemble the entire receiving box 29 regularly to take out the stored defective rods.

[0039] For the qualified rods, the push column 25 is connected to the material shell 23 to extrude the rods with the electric push rod 26. Since the height of the entire rolling box outlet is adjusted in advance by the cylinder 3, the rods pushed out by the push column 25 begin to enter the machine tool locking integration 2. Usually, a partition is set on the processing side of the frame 1 to limit the rod pushing position, and after the rod contacts the partition, the belt drives the internal parts of the machine tool locking integration 2 to rotate, complete the clamping of the outer wall of the rod, and then drives the entire clamped rod to rotate, and finally completes the bar milling processing on the other side of the frame 1, and the rolling cavity 21 continues to fill Material, and after the single-side bar material of the machine tool locking integration 2 is processed, the processed bar material is pushed out of the machine tool locking integration 2 by using a new bar material, so that the bar material can be processed uninterruptedly on the machine tool. Compared with the loading method of clamping and loading by a mechanical arm, the overall loading method is similar to the loading method of a bullet, and the loading rate is high, so that the processing rate of the entire bar material on the CNC machine tool is improved. At the same time, the entire material transfer box 4 and the sliding box 18 are more convenient to install in the frame 1, and the docking box 19 can be actively optimized at the same time, so as to further reduce the volume of the entire CNC machine tool automatic loading mechanism and improve the overall adaptability of the automatic loading mechanism.

[0040] Working principle of the present invention:

[0041] Use the cylinder 3 to push the material outlet side of the sliding box 18 to align with the feed port 5 of the machine tool lock material integration 2, and then put the bars to be processed from the feed port 5 of the material transfer box 4, start the motor on the material transfer box 4, and drive the rotating shaft 6 in the material transfer box 4 to rotate;

[0042] The rotation of the rotating shaft 6 realizes the rotation of the cam 8, drives the lifting plate 10 to rise, and when it reaches the top of one side of the material transfer box 4, the bar automatically falls along the inclined surface of the lifting plate 10 to the limiting groove 13 on the surface of the lifting block 12, and with the continuous rotation of the rotating shaft 6, the cam 29 on the rotating shaft 6 begins to contact the bottom pad 17 of the lifting block 12, driving the lifting block 12 to rise, and the inclined surface of the rotary disk 7 contacts the sleeve rod 14, so that the entire lifting block 12 slides inside the side frame 11, and then the lowered lifting block 12 places the received bar on the side frame 11, and under the subsequent rotation of the rotating shaft 6, the material moving and placing operations on the side frame 11 are repeated until the front end bar is sent to the side of the stopper 20;

[0043] The rods intercepted by the block 20 enter the sliding box 18 and are dynamically photographed by the CCD camera 22 while rolling in the rolling cavity 21. The photographs are then transmitted to an external computer for identification of the placement direction of the rods and the surface defects of the rods. When the rods fall onto the receiving shell 23, the rod decision signal is output. The qualified rods are moved by the electric push rod 26 and the push column 25 is driven to push the rods into the machine tool locking assembly 2 and are processed in cooperation with the cutting table on the other side of the frame 1. The unqualified rods are rotated 180° by the rotation of the swivel block 28, and the receiving shell 23 is automatically rotated into the receiving box 29.
