Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding of numerically controlled lathes, in particular to an automatic feeding device for numerically controlled lathes. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, reaming and boring, etc.

[0003] CNC machine tools automatically process the parts to be processed according to a pre-compiled processing program. We compile the parts' processing route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions into a processing program sheet according to the instruction code and program format specified by the CNC machine tool. We then record the contents of this program sheet on the control medium and then input it into the CNC device of the CNC machine tool to command the machine tool to process parts.

[0004] At present, when using CNC machine tools to process parts, conveyor belts and other conveying tools are usually used to transport the parts so that the speed of part transportation matches the speed of part processing by the CNC machine tools. Therefore, after the first part is processed, the second part is transported to the processing site and can be processed better.

[0005] When using a conveying structure to transport the connecting parts, since the processing position of the connecting parts is fixed, it is necessary to keep the position of the connecting parts during transportation. However, when the parts are currently transported, it is easy to cause them to shake during the transportation process, thereby affecting the subsequent processing of the parts. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide an automatic feeding device for a CNC lathe to solve the problem that when a conveying structure is used to transport the connecting parts, since the processing position of the connecting parts is fixed, it is necessary to maintain the position of the connecting parts during transportation. However, when the parts are currently transported, it is easy to cause them to shake during the transportation process, thereby affecting the technical problem of later processing of the parts.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding device for a CNC lathe comprises a bracket, a plurality of first card slots are arranged on the top of the bracket, a movable block is movably connected in the bracket, and a driving structure is arranged between the bracket and the movable block, the movable block is a cavity, a plurality of second card slots which match the first card slots are arranged on the top of the movable block, a fixed slot is arranged on the top of the second card slot, and a sliding rod movably passes through the fixed slot, a pressing block is fixedly connected to the top of the sliding rod, and a movable plate is fixedly connected to the bottom of the sliding rod, a spring is arranged between the second card slot and the pressing block, and a plurality of air intake ports are arranged on the top of the second card slot.

[0008] By adopting the above technical solution, when the parts need to be transported, the movable block can be driven by the driving structure to move inside the bracket. After the movable block moves to the appropriate position, the part is stuck in the second slot. At this time, the part presses the pressing block in the second slot according to its own gravity, so that the slide rod drives the pressing block to move downward, thereby squeezing the spring, causing the movable plate to move downward synchronously. Therefore, the movable plate does not block the air intake port, and the air intake port generates suction on the part, which is beneficial to keep the position of the part in an inconvenient manner during the part transportation process, so that it is better to use the CNC lathe to process it.

[0009] The utility model is further configured as follows: the driving structure includes a pair of rotating shafts rotatably connected in the bracket, and one end of the rotating shaft movably passes through the eccentric wheel and extends to the outside to be connected to a movable rod, a connecting block is provided between the eccentric wheel and the movable rod, and the connecting block is rotatably connected to the rotating shaft, one end of the movable rod is fixedly connected to one side of the movable block, and the pair of eccentric wheels are connected by a connecting rod, one end of one of the rotating shafts movably passes through one side of the bracket and extends to the outside to be connected to the output end of the motor, and the motor is placed on one side of the bracket through a support plate.

[0010] By adopting the above technical solution, one of the rotating shafts and the eccentric wheel is driven to rotate by a motor, and then the other rotating shaft and the eccentric wheel are driven to rotate synchronously by a connecting rod. The rotating shaft and the eccentric wheel are rotated inside the bracket, so that the movable rod drives the movable block to rotate inside the bracket, which is beneficial to the transmission of parts through the second slot on the top of the movable block, making it easier to transmit and thus better process the parts.

[0011] The utility model is further configured that a groove is arranged on the top of the bracket, a connecting pipe is movably penetrated through the bottom of the movable block, and a connecting head is arranged on the other end of the connecting pipe.

[0012] By adopting the above technical solution, a connecting pipe is provided at the bottom of the movable block, and an external air pump device can be connected through a connecting head, so that suction can be provided for the air intake port to prevent the parts from shaking during the transmission process and affecting the later processing of the parts.

[0013] The utility model is further configured that a plurality of rubber pads matching the position and size of the air inlet are arranged on the top of the movable plate.

[0014] By adopting the above technical solution, a plurality of rubber pads that switch with the position and size of the air intake port are arranged on the top of the movable plate. This is beneficial in that when the air intake port is not needed to fix the position of the part, the bottom of the air intake port can be blocked by the rubber pad, thereby preventing the air intake port from absorbing gaseous substances and affecting the use of the device.

[0015] The utility model is further configured that a first oblique rod is arranged at one end of the bracket, and a second oblique rod is arranged at the other end of the bracket.

[0016] By adopting the above technical solution, by arranging a first inclined rod at one end of the bracket, it is beneficial to place the parts together at one end of the bracket through the first inclined rod, which is convenient for better conveying the parts. At the same time, the second inclined rod at the other end of the bracket is beneficial for the completed parts to enter the processing area through air.

[0017] The utility model is further configured such that the fixing groove can accommodate the compressed spring and the pressing block.

[0018] By adopting the above technical solution, when the part presses the pressing block and the spring, the spring and the pressing block can be stored in the fixing groove, which is beneficial for connecting the outer surface of the part with the bottom of the second groove. The position of the part can be fixed through the air suction port, which is convenient for later processing of the part.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] When the utility model transmits the parts, the driving structure can drive the movable block to move, and after the movable block moves to the appropriate position, the part is stuck in the second slot. At this time, the part presses the pressing block in the second slot according to its own gravity, so that the sliding rod drives the pressing block to move downward, thereby squeezing the spring, so that the movable plate moves downward synchronously, and the air intake port generates suction on the part, which is beneficial to keep the position of the part in the process of transmitting the part, and is convenient for better using a CNC lathe to process it. At the same time, after the movable block drives the conveyed part to reach the first slot, the first slot supports the part, and the pressing force exerted on the pressing block disappears. At this time, the resetting of the spring drives the movable plate, the sliding rod, and the pressing block to move upward synchronously, so that the movable plate blocks the air intake port, which is beneficial to complete the transmission of the parts.

DETAILED DESCRIPTION

[0027] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] Automatic feeding device for CNC lathe, such as Figure 1-5 As shown, it includes a bracket 1, and a first inclined rod 2 is arranged at one end of the bracket 1.

At the same time, a second inclined rod 3 is arranged at the other end of the bracket 1, which is conducive to reaching the designated position through the second inclined rod 3 after the parts are transmitted by the movable block 6, so as to facilitate processing thereof.

[0030] Then, a movable block 6 is movably connected in the bracket 1, and a driving structure is provided between the bracket 1 and the movable block 6, which is conducive to driving the movable block 6 to move inside the bracket 1 through the driving structure. The movable block 6 is a cavity 7, and a plurality of air intake ports 12 are provided on the top of the second card slot 24, which is conducive to fixing the position of the part through the air intake port 12 when the air intake port 12 is not blocked, so as to avoid shaking during the transmission of the part, which affects the processing of the part by the CNC machine tool in the later stage. A plurality of second card slots 24 that match the first card slot 4 are provided on the top of the movable block 6, so that when the movable block 6 drives the two parts to be transmitted, they can be placed in the first card slot 4 for staying, so as to better complete the transmission of the parts. At the same time, a The second slot 24 is provided with a spring 11, and the pressing block 10 is fixedly connected to the top of the slide bar 9, and the movable plate 13 is fixedly connected to the bottom of the slide bar 9. When the pressing block 10 is subjected to the weight of the part itself, the spring 11 is squeezed, so that the slide bar 9, the pressing block 10 and the movable plate 13 move downward, and the part is located inside the second slot 24, and the position of the part is fixed by the air intake port 12. At the same time, during the movement, after the part is placed inside the first slot 4, the spring 11 drives the slide bar 9, the pressing block 10 and the movable plate 13 to reset, and the movable plate 13 blocks the air intake port 12, so that the suction force cannot fix the part from the air intake port 12, which is conducive to better conveying the part.

[0031] At the same time, a plurality of rubber pads 14 that match the position and size of the air inlet 12 are arranged on the top of the movable plate 13, which is conducive to making the movable plate 13 close to the bottom of the second slot 24 after the spring 11 drives the movable plate 13 to reset, and is conducive to making the rubber pad 14 located at the bottom of the air inlet 12, thereby blocking the air inlet 12 and preventing the suction force generated by the air inlet 12 from sucking other substances, thereby affecting the use of the device.

[0032] The driving structure includes a pair of rotating shafts 17 rotatably connected in the bracket 1, and one end of the rotating shaft 17 movably penetrates the eccentric wheel 18 and extends to the outside to be connected with a movable rod 21, so that the rotating shaft 17 drives the eccentric wheel 18 and the movable rod 21 to move, and a connecting block 20 is arranged between the eccentric wheel 18 and the movable rod 21 to reduce the influence between the eccentric wheel 18 and the movable rod 21, and the connecting block 20 is rotatably connected with the rotating shaft 17, so that the rotating shaft 17 rotates inside the connecting block 20, and one end of the movable rod 21 is fixedly connected to one side of the movable block 6, so that the movable block 6 can be driven to move inside the bracket 1 through the movable rod 21, and at the same time, The eccentric wheels 18 are connected by connecting rods 19, so that when one of the eccentric wheels 18 rotates, the other eccentric wheel 18 can be synchronously driven to rotate by the connecting rod 19. One end of one of the rotating shafts 17 movably passes through one side of the bracket 1 and extends to the outside where the output end of the motor 22 is connected, which is conducive to driving one of the rotating shafts 17 to rotate by the motor 22. When the other eccentric wheel 18 is driven to rotate by the connecting rod 19, it can drive the movable block 6 to move inside the bracket 1, and the motor 22 is placed on one side of the bracket 1 through the support plate 23, which is conducive to fixing the position of the motor 22 through the support plate 23.

[0033] A groove 5 is further provided at the top of the bracket 1, and a connecting pipe 15 is movably penetrated through the bottom of the movable block 6, and a connecting head 16 is provided at the other end of the connecting pipe 15, which is conducive to connecting an external air pump device through the connecting head 16, so that it can provide suction to the movable block 6 through the connecting pipe 15. At the same time, the connecting head 16 and the air pump device can be connected through a bellows, thereby avoiding affecting the rotation of the movable block 6.

[0034] In this embodiment, the fixing groove 8 can accommodate the compressed spring 11 and the pressing block 10, so that the spring 11 and the pressing block 10 are completely accommodated in the fixing groove 8, which is beneficial for the air intake port 12 to contact the bottom of the part, so the position of the part can be fixed to avoid shaking during the part transmission process, causing position deviation, thereby affecting the later processing of the part.
