[0002] A sliding headstock lathe, also known as a spindle box moving type CNC automatic lathe, an economical turning and milling compound machine tool or a longitudinal cutting lathe for short. It belongs to precision machining equipment and can simultaneously complete compound machining such as turning, milling, drilling, boring, tapping, engraving, etc. at one time. It is mainly used for batch processing of precision hardware and special-shaped non-standard parts of shafts.

[0003] In the prior art, a Chinese patent with the publication number CN206122715U discloses a sliding headstock lathe, which includes a machine frame. On one side of the machine frame, a spindle center is provided, and on the other side, a tailstock center is slidably arranged along the axial direction of the spindle center. The tailstock center is provided with a fixing device for fixing the tailstock center on the machine frame. A supporting part for supporting shaft parts is arranged on the machine frame, and the supporting part is connected with a driving part for moving the supporting part to the spindle center and keeping the shaft parts coaxial with the spindle center. The key point of its technical solution is that the driving part pushes the supporting part to approach the shaft parts, supports the shaft parts, and the shaft parts on the supporting part are coaxial with the spindle center. At this time, the operator pushes the tailstock center to approach the shaft parts and clamps the shaft parts between the spindle center and the tailstock center to achieve automatic alignment of the shaft parts. When implementing the above solution, when loading and unloading the sliding headstock lathe, the workpieces are usually placed on a material rack on one side of the sliding headstock lathe, and then the workpieces are clamped and installed on the fixture of the sliding headstock lathe by a robotic arm for processing. Since multiple workpieces are usually placed flat on the material rack, when the robotic arm clamps materials at different positions on the material rack, it needs to move a large range, which affects the loading efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide an automatic loading device for a sliding headstock lathe aiming at the above technical problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An automatic loading device for a sliding headstock lathe, comprising: A conveying assembly for conveying the stacked workpieces, and a robotic arm assembly is arranged on one side of the conveying assembly; A top extension plate, the top extension plate is arranged at the output end of the conveying assembly, and a telescopic member is installed at the bottom of the top extension plate; Inverting loading mechanism, the inverting loading mechanism includes an inverting seat placed above the top extension plate, a first positioning cylinder fixed to the top of the inverting seat, and a second positioning cylinder fixed to the bottom of the inverting seat and corresponding to the first positioning cylinder. A plurality of elastic locking blocks one are embedded in the outer ring of the first positioning cylinder along its axial direction, and a plurality of elastic locking blocks two are embedded in the outer ring of the second positioning cylinder along its axial direction.

[0006] As a preferred embodiment of the automatic loading device of the sliding headstock machine provided by the present invention, the installation positions of the first positioning cylinder and the second positioning cylinder on the inverting seat correspond to the hole positions on the workpiece. Arc chamfers are provided at the ends of the first positioning cylinder and the second positioning cylinder. When the workpiece is pushed up by the top extension plate, the first positioning cylinder and the second positioning cylinder with arc chamfers can accurately plug into the hole positions on the workpiece, achieving the purpose of installing and fixing the workpiece and facilitating the loading of the workpiece.

[0007] As a preferred embodiment of the automatic loading device of the sliding headstock machine provided by the present invention, an installation frame is fixed to the housing of the conveying component. The inverting seat is rotatably connected to the installation frame, and a first driving member with an output end connected to the inverting seat is installed on the installation frame. By setting the installation frame, the height of the inverting seat can be limited, so that each time the workpiece is inverted, it can be inverted to a specified position. By operating the first driving member to drive the inverting seat to rotate, the workpiece limited at the bottom of the inverting seat is inverted to the upper end, achieving the purpose of automatic control.

[0008] As a preferred embodiment of the automatic loading device of the sliding headstock machine provided by the present invention, both the elastic locking blocks one and the elastic locking blocks two are made of rubber. The distance between adjacent elastic locking blocks one is the same as the height of the workpiece, and the distance between adjacent elastic locking blocks two is the same as the height of the workpiece. When the stacked workpieces are plugged into the first positioning cylinder, the elastic locking blocks one on the first positioning cylinder abut against the corresponding workpiece to fix the workpiece. Similarly, when the stacked workpieces are plugged into the second positioning cylinder, the elastic locking blocks two on the second positioning cylinder abut against the corresponding workpiece to fix the workpiece.

[0009] As a preferred embodiment of the automatic loading device of the sliding headstock provided by the present invention, a control cavity one is provided in the middle of the positioning cylinder one, and a control cavity two is provided in the middle of the positioning cylinder two. An adjusting insertion rod is inserted into each positioning cylinder one, and the lower end of the adjusting insertion rod extends into the control cavity two of the positioning cylinder two corresponding to the positioning cylinder one. When the adjusting insertion rod moves in the inner cavities of the positioning cylinder one and the positioning cylinder two, when the adjusting insertion rod abuts against the elastic locking block one or the elastic locking block two, it will control the outer wall of the elastic locking block one or the elastic locking block two to expand, increasing the outer wall diameter of the elastic locking block one or the elastic locking block two. On the contrary, when the adjusting insertion rod does not abut against the elastic locking block one or the elastic locking block two, the outer wall of the elastic locking block one or the elastic locking block two contracts, reducing the outer wall diameter of the elastic locking block one or the elastic locking block two.

[0010] As a preferred embodiment of the automatic loading device of the sliding headstock provided by the present invention, the wall thickness of the elastic locking block one is greater than the wall thickness of the positioning cylinder one, and the wall thickness of the elastic locking block two is greater than the wall thickness of the positioning cylinder two. When the adjusting insertion rod is inserted into the positioning cylinder one and abuts against the inner wall of the elastic locking block one, it pushes the elastic locking block one to expand outward. The outer diameter of the expanded elastic locking block one is greater than the outer diameter of the positioning cylinder one. Similarly, when the adjusting insertion rod is inserted into the positioning cylinder two and abuts against the inner wall of the elastic locking block two, it pushes the elastic locking block two to expand outward. The outer diameter of the expanded elastic locking block two is greater than the outer diameter of the positioning cylinder two, and the workpiece located on the positioning cylinder one or the positioning cylinder two is locked more stably.

[0011] As a preferred embodiment of the automatic loading device of the sliding headstock provided by the present invention, arc chamfers are provided at both the upper and lower ends of the adjusting insertion rod, and the outer ring of the adjusting insertion rod is coated with grease, which is convenient for the stable up and down movement of the adjusting insertion rod and its insertion into the elastic locking block one and the elastic locking block two.

[0012] As a preferred embodiment of the automatic loading device of the sliding headstock provided by the present invention, a control groove is axially provided on the outer wall of each adjusting insertion rod, and a control wheel is correspondingly arranged in each control groove. A plurality of control wheels are linked by a linkage assembly, and a driving part two is installed on the linkage assembly. The driving part two is installed in the installation position on the flipping seat. By driving the linkage assembly to work by the driving part two, the linkage assembly controls the rotation of a plurality of control wheels. The control wheels roll in the control grooves on the corresponding adjusting insertion rods, thereby controlling the up and down movement of the adjusting insertion rods, which is convenient for the simultaneous linkage control of a plurality of adjusting insertion rods. In addition, the linkage assembly is a connecting rod and gear structure. By controlling the rotation of the connecting rod by the driving part two and driving a plurality of control wheels to rotate by the gear assembly, the simultaneous forward or reverse rotation of a plurality of control wheels is realized.

[0013] As a preferred embodiment of the automatic feeding device of the gang-type automatic lathe provided by the present invention, a limiting block is fixed at one end of the top extension plate away from the output end of the conveying component. The limiting block is in contact with the side of the workpiece transferred onto the top extension plate. By setting the limiting block, when the stacked workpieces are transferred onto the top extension plate, they will be in contact with the limiting block, and the position of the workpiece is limited by the limiting block, so that when the top extension plate drives the workpiece to move upward, it is inserted into the corresponding positioning cylinder 1 or positioning cylinder 2.

[0014] As a preferred embodiment of the automatic feeding device of the gang-type automatic lathe provided by the present invention, a guide rod is fixed at the bottom of the top extension plate. The guide rod is vertically inserted into the housing of the conveying component. By setting the guide rod, it is convenient to control the stable vertical movement of the top extension plate and dock the workpiece with the corresponding positioning cylinder 1 or positioning cylinder 2.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. For the automatic feeding device of the gang-type automatic lathe provided by the present invention, when the top extension plate moves upward, the positioning cylinder 2 gradually inserts into the hole position on the workpiece. Through the elastic locking block 2 provided on the positioning cylinder 2, the elastic locking block 2 made of elastic material limits the workpiece, so as to insert and fix the workpiece with the positioning cylinder 2, which is convenient to quickly install multiple stacked workpieces onto the flipping seat, and the driving part 1 works to drive the flipping seat to flip, turning the stacked workpieces upward so that the surface to be machined faces upward. Since the workpieces are stacked vertically and are limited and fixed by the corresponding positioning cylinder 2 or positioning cylinder 1, at this time, the robotic arm assembly on one side of the gang-type automatic lathe assembly clamps the stacked workpieces in sequence. Since the workpieces are stacked and arranged, the overall movement range of the robotic arm assembly during the clamping and feeding process is small, realizing rapid feeding, and being limited and fixed by the positioning cylinder 2 or positioning cylinder 1, ensuring the stability of the workpiece. When installing the gang-type automatic lathe assembly and the robotic arm assembly, a smaller space can be planned for installation, improving the utilization rate of the factory space.

[0016] 2. An automatic feeding device for a sliding headstock lathe provided by the present invention. When the first positioning cylinder drives the workpiece to be flipped upwards, at this time, the top extension plate pushes the workpiece upwards to be inserted into the second positioning cylinder. When the robotic arm assembly clamps the workpiece on the first positioning cylinder, at this time, by controlling the adjusting rod to move downwards along the inner cavity of the first control cavity, the top of the adjusting rod gradually disengages from the corresponding first elastic locking block. As shown in the figure, the outer diameter of the first elastic locking block gradually shrinks. The first elastic locking block with the shrunk outer diameter will release the limit of the workpiece, thereby reducing the clamping resistance of the robotic arm assembly. In addition, during the downward movement of the adjusting rod, it will gradually be inserted into the second positioning cylinder, and the outer diameter of the second elastic locking block will expand to lock the workpiece on the second positioning cylinder. And during the sequential downward movement of the adjusting rod, the workpieces on the upper first positioning cylinder are sequentially unlocked, and the workpieces on the second positioning cylinder are sequentially locked. Thus, after the workpieces on the first positioning cylinder are completely unlocked, all the workpieces on the second positioning cylinder are locked. At this time, by controlling the first driving part to work, the workpieces locked on the second positioning cylinder can be flipped upwards, improving the operation convenience and efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0022] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Embodiment 1

[0023] Please refer to Figures 1 - 5, An automatic feeding device for a sliding headstock lathe, comprising a conveying component 3, a top extension plate 6, and a flipping feeding mechanism 5. The conveying component 3 is used to convey the stacked workpieces 4, and the workpieces 4 are provided with hole positions 24 at four corners. After the workpieces 4 are manually stacked, they are placed on the conveying component 3. Through the operation of the conveying component 3, each stack of stacked workpieces 4 is gradually conveyed to the top extension plate 6. The conveying component 3 is a common conveyor belt in the prior art, and cylinders 25 are arranged on both sides of the top extension plate 6. The output ends of the cylinders 25 are connected with positioning plates 26, which are used to limit the two sides of the stacked workpieces 4 to make them flush, so that the stacked workpieces 4 can be accurately placed at the specified position on the top extension plate 6; the top extension plate 6 is arranged at the output end of the conveying component 3, and a telescopic member 7 is installed at the bottom of the top extension plate 6. By operating the telescopic member 7, the top extension plate 6 is pushed to move up and down, controlling the up and down movement of the workpiece 4 moved to the top extension plate 6. A robotic arm assembly 2 is arranged on one side of the conveying component 3, and clamping is performed through the robotic arm assembly 2 to assist in loading and unloading.

[0024] The flipping feeding mechanism 5 includes a flipping seat 8 placed above the top extension plate 6, a positioning cylinder one 10 fixed to the top of the flipping seat 8, and a positioning cylinder two 11 fixed to the bottom of the flipping seat 8 and corresponding to the positioning cylinder one 10. A plurality of elastic locking blocks one 13 are embedded along the axial direction of the outer ring of the positioning cylinder one 10, and a plurality of elastic locking blocks two 14 are embedded along the axial direction of the outer ring of the positioning cylinder two 11. Both the elastic locking blocks one 13 and the elastic locking blocks two 14 are elastic rubber blocks, which are connected to the positioning cylinder one 10 and the positioning cylinder two 11 respectively by vulcanization molding.

[0025] When the top extension plate 6 moves upward, it pushes the stacked workpieces 4 to move upward. The workpieces 4 move upward and gradually approach the positioning cylinder two 11 at the bottom of the flipping seat 8. The positioning cylinder two 11 gradually inserts into the hole positions 24 on the workpieces 4. Through the elastic locking blocks two 14 arranged on the positioning cylinder two 11, the elastic locking blocks two 14 made of elastic material limit the workpieces 4, thereby inserting and fixing the workpieces 4 with the positioning cylinder two 11, facilitating the rapid installation of multiple stacked workpieces 4 onto the flipping seat 8. Then, by operating the driving member one 9, the flipping seat 8 is driven to flip, flipping the stacked workpieces 4 upward. Since the workpieces 4 are stacked vertically and are limited and fixed by the corresponding positioning cylinder two 11 or positioning cylinder one 10, at this time, the robotic arm assembly 2 on one side of the sliding headstock lathe assembly 1 clamps the stacked workpieces 4 in sequence. Since the workpieces 4 are stacked and arranged, the overall movement amplitude of the robotic arm assembly 2 during the clamping and feeding process is relatively small, realizing rapid feeding, and being limited and fixed by the positioning cylinder two 11 or positioning cylinder one 10, ensuring the stability of the workpieces 4; and after the workpieces 4 are flipped, the required machining surface faces upward, and the machining surface can face the cutting tool after the robotic arm assembly 2 feeds.

[0026] In addition, when the second positioning cylinder 11 with the workpiece 4 inserted is reversed upwards, the corresponding first positioning cylinder 10 is flipped downwards. At this time, the top extension plate 6 is used to push the workpiece 4 upwards again to be inserted into the corresponding first positioning cylinder 10, so as to load the stacked workpieces 4 in sequence. In addition, the stacked workpieces 4 are flipped to the machining state through the flipping seat 8. Therefore, when stacking the workpieces 4 on the conveying assembly 3, the workpieces 4 can be buckled on the conveying assembly 3 in the direction opposite to the machining state, which is convenient for loading the workpieces 4 through flipping. After the sliding headstock assembly 1 finishes machining the workpiece 4, the mechanical arm assembly 2 is used to remove the sliding headstock assembly 1 for unloading.

[0027] In this embodiment, the installation positions of the first positioning cylinder 10 and the second positioning cylinder 11 on the flipping seat 8 correspond to the hole positions 24 on the workpiece 4. Arc-shaped chamfers are provided at the ends of the first positioning cylinder 10 and the second positioning cylinder 11. When the top extension plate 6 moves upwards to push the workpiece 4 upwards, the first positioning cylinder 10 and the second positioning cylinder 11 with arc-shaped chamfers can accurately be inserted into the hole positions 24 on the workpiece 4, achieving the purpose of installing and fixing the workpiece 4 and facilitating the loading of the workpiece 4.

[0028] In addition, please refer to Figure 2 and Figure 3 , an installation frame 12 is fixed on the housing of the conveying assembly 3. The flipping seat 8 is rotatably connected to the installation frame 12. A first driving member 9 with an output end connected to the flipping seat 8 is installed on the installation frame 12. By setting the installation frame 12, the height of the flipping seat 8 can be limited, so that each time the workpiece 4 is flipped, it can be flipped to the specified position. By the operation of the first driving member 9 to drive the flipping seat 8 to rotate, the workpiece 4 limited at the bottom of the flipping seat 8 is flipped to the upper end, achieving the purpose of automatic control. In addition, the distance between adjacent first elastic locking blocks 13 is the same as the height of the workpiece 4, and the distance between adjacent second elastic locking blocks 14 is the same as the height of the workpiece 4. When the stacked workpieces 4 are inserted into the first positioning cylinder 10, the first elastic locking blocks 13 on the first positioning cylinder 10 abut against the corresponding workpieces 4 to fix the workpieces 4. Similarly, when the stacked workpieces 4 are inserted into the second positioning cylinder 11, the second elastic locking blocks 14 on the second positioning cylinder 11 abut against the corresponding workpieces 4 to fix the workpieces 4.

[0029] Preferably, as Figure 2 and Figure 4As shown, a limit block 22 is fixed at one end of the top extension plate 6 away from the output end of the conveying assembly 3, and the limit block 22 is in contact with the side of the workpiece 4 transferred to the top extension plate 6. By setting the limit block 22, when the stacked workpiece 4 is transferred to the top extension plate 6, it will be in contact with the limit block 22, and the position of the workpiece 4 is limited by the limit block 22. Combined with the operator on one side, the stacked workpiece 4 can be further moved to conflict with one side of the limit block 22, and then the cylinder 25 drives the two positioning plates 26 to move toward each other, so that the stacked workpiece 4 can be accurately placed at the specified position on the top extension plate 6. When the top extension plate 6 drives the workpiece 4 to move upward, it is plugged into the corresponding positioning cylinder 10 or positioning cylinder 2 11. A guide rod is fixed to the bottom of the top extension plate 6, and the guide rod is vertically plugged into the shell of the conveying assembly 3. By setting the guide rod, it is easy to control the stable vertical movement of the top extension plate 6 and connect the workpiece 4 with the corresponding positioning cylinder 10 or positioning cylinder 2 11. Example 2

[0030] The automatic loading device of a Swiss-type lathe provided in the first embodiment is further optimized. Different from the first embodiment, when the workpiece 4 is plugged into the corresponding positioning cylinder 2 11 or positioning cylinder 2 11, the workpiece 4 is usually locked and limited by the elastic locking block 13 on the positioning cylinder 10 and the elastic locking block 2 14 on the positioning cylinder 2 11. In order to prevent the workpiece 4 from escaping from the positioning cylinder 10 or the positioning cylinder 2 11 during the flipping process, Figures 5 - 10 As shown, a regulating cavity 1 20 is provided in the middle of the positioning cylinder 10, and a regulating cavity 21 is provided in the middle of the positioning cylinder 2 11. An adjusting rod 15 is inserted in each positioning cylinder 10, and the lower end of the adjusting rod 15 extends to the regulating cavity 21 of the positioning cylinder 2 11 corresponding to the positioning cylinder 10. When the adjusting rod 15 moves in the inner cavity of the positioning cylinder 10 and the positioning cylinder 2 11, when the adjusting rod 15 abuts against the elastic locking block 13 or the elastic locking block 2 14, the elastic locking block 13 or the elastic locking block 2 will be squeezed. The outer wall of the tightening block 14 makes it protrude from the regulating cavity 1 20 or the regulating cavity 2 21, thereby increasing the outer wall diameter of the positioning cylinder 10 or the positioning cylinder 2 11 in which the elastic locking block 13 or the elastic locking block 2 14 is located. Conversely, when the adjusting rod 15 is not in contact with the elastic locking block 13 or the elastic locking block 2 14, the outer wall of the elastic locking block 13 or the elastic locking block 2 14 shrinks, thereby reducing the outer wall diameter of the positioning cylinder 10 or the positioning cylinder 2 11 in which the elastic locking block 13 or the elastic locking block 2 14 is located.

[0031] Through the above structural design, when the positioning cylinder 1 drives the workpiece 4 to turn upwards, at this time, the top extension plate 6 pushes the workpiece 4 to move upwards and is inserted into the positioning cylinder 2 11. When the robotic arm assembly 2 clamps the workpiece 4 on the positioning cylinder 1, at this time, by controlling the adjustment rod 15 to move downwards along the inner cavity of the adjustment cavity 1 20, the top of the adjustment rod 15 gradually disengages from the corresponding elastic locking block 1 13, as Figure 8 shown. The outer diameter of the elastic locking block 1 13 gradually shrinks. The elastic locking block 1 13 with the shrunk outer diameter will release the limit of the workpiece 4, thereby reducing the resistance of the robotic arm assembly 2 during clamping. In addition, during the downward movement of the adjustment rod 15, it will gradually insert into the positioning cylinder 2 11, and the outer diameter of the elastic locking block 2 14 will expand, locking the workpiece 4 on the positioning cylinder 2 11. And during the sequential downward movement of the adjustment rod 15, the workpieces 4 on the upper positioning cylinder 1 are sequentially unlocked, and the workpieces 4 on the positioning cylinder 2 11 are sequentially locked. Thus, after the workpieces 4 on the positioning cylinder 1 are completely unlocked, all the workpieces 4 on the positioning cylinder 2 11 are locked. At this time, by controlling the driving part 1 9 to work, the locked workpiece 4 on the positioning cylinder 2 11 can be turned upwards, improving the convenience of operation and the efficiency.

[0032] Preferably, as Figure 7 shown, the wall thickness of the elastic locking block 1 13 is greater than the wall thickness of the positioning cylinder 1, and the wall thickness of the elastic locking block 2 14 is greater than the wall thickness of the positioning cylinder 2 11. When the adjustment rod 15 is inserted into the positioning cylinder 1 and abuts against the inner wall of the elastic locking block 1 13, it pushes the elastic locking block 1 13 to expand outwards. The outer diameter of the expanded elastic locking block 1 13 is greater than the outer diameter of the positioning cylinder 1. Similarly, when the adjustment rod 15 is inserted into the positioning cylinder 2 11 and abuts against the inner wall of the elastic locking block 2 14, it pushes the elastic locking block 2 14 to expand outwards. The outer diameter of the expanded elastic locking block 2 14 is greater than the outer diameter of the positioning cylinder 2 11, more stably locking the workpiece 4 located on the positioning cylinder 1 or the positioning cylinder 2 11. In addition, arc chamfers are provided at both the upper and lower ends of the adjustment rod 15, and the outer ring of the adjustment rod 15 is coated with lubricating grease, facilitating the stable up and down movement of the adjustment rod 15 and its insertion into the elastic locking block 1 13 and the elastic locking block 2 14.

[0033] It is worth mentioning that, as Figure 6As shown, a control groove 16 is axially formed in the outer wall of each adjusting rod 15, and a control wheel 17 is correspondingly arranged in each control groove 16. A plurality of control wheels 17 are linked by a linkage assembly 18. A second driving member 19 is installed on the linkage assembly 18. The linkage assembly 18 and the second driving member 19 are both installed in the installation position 23 on the turning base 8. By driving the linkage assembly 18 to work with the second driving member 19, the linkage assembly 18 controls the rotation of a plurality of control wheels 17. The control wheels 17 roll in the control grooves 16 on the corresponding adjusting rods 15, and the up-and-down movement of the adjusting rods 15 is controlled by the friction between the two, which is convenient for the simultaneous linkage control of a plurality of adjusting rods 15. In addition, the linkage assembly 18 is a connecting rod and gear structure. By controlling the rotation of the connecting rod with the second driving member 19 and driving a plurality of control wheels 17 to rotate through the gear assembly, the simultaneous forward or reverse rotation of a plurality of control wheels 17 is achieved. In this embodiment, the gear assembly is connected by bevel gears, and the two connecting rods are respectively connected to one of the bevel gears.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly defined.
