Technical Field

[0001] The invention relates to the technical field of loading and unloading of tool grinders, in particular to a double-disc tool grinder with automatic loading and unloading functions. Background Art

[0002] In the manufacturing process of products, loading and unloading equipment can transport materials to be processed to processing equipment for processing, and can output materials processed by processing equipment. In the loading and unloading process, traditional loading and unloading equipment provides trays carrying materials to be processed for the loading end of the processing equipment, and stacks the empty trays after the materials to be processed are taken out by the processing equipment, and transports the stacked empty trays to the unloading end manually or by a conveyor vehicle, and provides a large number of empty trays at the unloading end to receive the materials processed by the processing equipment, resulting in insufficient utilization of tray resources by the loading and unloading equipment, wasting manpower, and occupying a large space.

[0003] The loading and unloading modules of machining machine tools are important components of machining machine tools, especially machining machine tools with a high degree of automation integration. The efficiency and stability of loading and unloading determine the overall efficiency and performance of machining machine tools. Since machining machine tools are different from production lines or processing lines, the bed area of ​​machining machine tools is limited. How to reasonably arrange various components on the limited bed to improve the processing efficiency and performance of machining machine tools is a difficult problem that technical personnel in the industry need to continuously overcome and improve.

[0004] A Chinese patent document with publication number CN116900828A discloses an automatic loading and unloading five-axis CNC tool grinder and a processing method. The automatic loading and unloading five-axis CNC tool grinder includes a grinder mechanism, a protective cover mounted on the upper surface of the grinder mechanism, a control computer installed on one side of the grinder mechanism, and a grinding oil circulation treatment device connected to the grinder mechanism and the protective cover. The grinder mechanism includes a base, a workpiece moving mechanism installed on the base, a combined grinding wheel grinding mechanism, a workpiece loading and unloading mechanical mechanism and a magnetic suction mechanism; the workpiece moving mechanism includes a first moving seat for forward and backward movement of the X-axis, a fixture mounting frame mounted on the first moving seat, a fixture frame mounted on the fixture mounting frame through a rotating seat, a first rotating motor installed on the fixture mounting frame that can drive the fixture frame to rotate as a whole around the C-axis perpendicular to the first moving seat, a fixture movably mounted on the fixture frame, and a second rotating motor installed on the fixture frame that controls the fixture to rotate around the fixture's own rotating axis A-axis.

[0005] The Chinese patent document with the announcement number CN221564747U discloses a silo used for loading and unloading materials on a machine tool, which comprises: a frame, wherein the left side and the right side of the frame are respectively provided with a raw material area and a finished product area; a silo mechanism, wherein the silo mechanism comprises a loading conveyor belt and a loading support rod arranged in the raw material area, and a unloading conveyor belt and a unloading support rod arranged in the finished product area; the loading conveyor belt and the unloading conveyor belt are both arranged on the frame so as to rotate forward and backward, and the loading support rod and the unloading support rod are both movable up and down. Arranged on the frame; multiple loading conveyor belts and multiple loading support rods are arranged at intervals, and multiple unloading conveyor belts and multiple unloading support rods are arranged at intervals; wherein, the length of the loading conveyor belt is greater than the length of the loading support rod, and the length of the unloading conveyor belt is greater than the length of the unloading support rod; when the loading support rod is in the first position, the upper plane of the loading support rod is lower than the upper plane of the loading conveyor belt; when the unloading support rod is in the second position, the upper plane of the unloading support rod is lower than the upper plane of the unloading conveyor belt.

[0006] Most of the existing processing machine tools use material racks to store materials. Loading racks and unloading racks are set in front of the processing table. Manual personnel are required to pay attention to the material capacity in the racks at all times, and they need to manually replace the empty loading racks and remove the fully loaded unloading racks in time. Some processing machine tools are set in front of the machine tool processing table in the form of conveyor belts, which greatly improves the loading efficiency of the processing machine tools, but the conveyor line will occupy a large space on the bed, which is not conducive to the structural optimization and cost reduction of the bed. Some processing machine tools only use one material tray for material transfer. When it is necessary to conduct random inspections on multiple tools processed in this batch, a single material tray cannot meet the transportation needs of the random inspection tools. Summary of the invention

[0038] According to the requirements, the robot arm 4 is an existing well-known technology, such as a six-axis robot arm. The first slide 7, the second slide 11, the clamping spindle 8, the grinding electric spindle 13 and the working turntable 2 are all existing well-known technologies. The working turntable 2 can rotate around its own central axis in a horizontal plane, thereby driving the clamping spindle 8 and the tailstock 9 to rotate in the horizontal plane. The working turntable 2 is arranged above the front part of the bed 1, and the mounting seat 12 is arranged above the rear part of the bed 1. During use, by setting up a robotic arm 4 and a gripping mechanism, the workpiece to be processed can be transferred to the clamping spindle 8, and the processed workpiece can be taken out from the clamping spindle 8 and placed on the first material tray 5 or the second material tray.

[0039] The above-mentioned double-disc tool grinder with automatic loading and unloading can be further optimized and / or improved according to actual needs: Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 3 , 6As shown in 8 to 12, the second material tray includes a fixed plate 15, a lower material plate 16 and an upper material plate 17 which are spaced from bottom to top.

[0041] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figure 2 , 3 As shown in 5 to 12, a plurality of material troughs 22 opening upward are spaced apart on the upper side of the first material tray 5, and a plurality of support columns are fixedly installed at circumferential intervals on the lower side of the first material tray 5. The support columns are in the shape of stepped shafts that are thick on the top and thin on the bottom. A fixed groove opening upward is provided on the upper side of the feeding platform 3 corresponding to the position of each support column, and the lower end of the support column is inserted into the fixed groove.

[0042] During use, by setting the first material tray 5 and the material trough 22, it is convenient to store the workpieces to be processed and the workpieces that have been processed, and the moving distance and movement difficulty of the robot arm 4 can be reduced, thereby shortening the time to move the workpieces to be processed on the first material tray 5 to the clamping spindle 8, and improving the processing efficiency of the workpieces. The support column is in the shape of a stepped shaft with a thick top and a thin bottom. In this way, the lower end of the support column is inserted into the fixed groove, so that a distance can be set between the lower side of the first material tray 5 and the upper side of the detection platform, which is convenient for the transportation of the first material tray 5.

On the right side of the rear part of the first positioning gripper 26, two first stepped surfaces 28 are arranged at intervals from right to left. On the front side and the rear side of each first stepped surface 28, a first chamfer 29 is provided. On the right side of the fixed seat 25 corresponding to the position between the first positioning gripper 26 and the second positioning gripper 27, a lower mounting hole 31 and an upper mounting hole 30 that penetrate left and right are arranged at intervals from bottom to top. A first rotating shaft 32 with its lower end passing through the lower side of the fixed seat 25 is rotatably installed on the inner wall of the lower mounting hole 31. The lower end of the first rotating shaft 32 is installed with a first driven gripper. The first driven gripper includes a mounting block 34, a connecting block 35 and a clamping finger 36. The lower end of the first rotating shaft 32 and the left part of the mounting block 34 are fixedly installed together. At the position corresponding to the two first stepped surfaces 28, a connecting block 35 is fixed to the rear right side of the mounting block 35. A clamping finger 36 is fixed to the right side of the connecting block 35. The left part of the clamping finger 36 is inclined backward relative to the right part.

The lower swing assembly can drive the first rotating shaft 32 to rotate so that the front side of the clamping finger 36 and the rear side of the first positioning gripper 26 approach or move away from each other. The upper swing assembly 38 can drive the second rotating shaft 33 to rotate so that the rear side of the second driven gripper 37 and the front side of the second positioning gripper 27 move away from or approach each other.

[0044] During the use process, by setting the first positioning gripper 26 and the second positioning gripper 27, the first positioning gripper 26 can place the processed workpiece on the first tray 5, and at the same time, the second positioning gripper 27 grabs the next workpiece to be processed into the clamping spindle 8. This can reduce the movement of the robotic arm 4, thereby saving the tool transfer time and improving the production efficiency.

[0045] Embodiment Five: As an optimization of the above embodiment, as shown in the appendix Figures 8 to 12As shown in the figure, the lower swing assembly includes a central shaft 40, a cylinder sleeve 41, a sealing piston 42, and a lower rocker arm 43. A forward and backward hollow central shaft 40 is fixedly installed inside the lower part of the fixed seat 25. An air inlet hole 44 is provided on the left side of the front part of the fixed seat 25, and the other end of the air inlet hole 44 communicates with the front end of the central shaft 40. An air outlet hole 45 is provided on the left side of the rear part of the fixed seat 25, and the other end of the air outlet hole 45 communicates with the rear end of the central shaft 40. A cylinder sleeve 41 is hermetically sleeved outside the central shaft 40. The front and rear of the central shaft 40 at the position corresponding to the inside of the cylinder sleeve 41 are provided with a front air outlet 46 and a rear air outlet 47 that communicate inside and outside at intervals. A sealing column 39 is fixedly installed inside the central shaft 40 at the position corresponding to the middle of the front air outlet 46 and the rear air outlet 47 in a sealed manner. A sealing piston 42 is fixedly installed outside the central shaft 40 at the position corresponding to the middle of the front air outlet 46 and the rear air outlet 47. The outside of the sealing piston 42 is in sealed contact with the inside of the cylinder sleeve 41. The lower rocker arm 43 is in a U shape with an opening to the left. Long circular movable grooves 48 are provided symmetrically up and down on the lower side and the upper side of the right part of the cylinder sleeve 41. An activity pin 49 is provided in each movable groove 48, and each activity pin 49 is fixedly installed together with the corresponding position on the left part of the lower rocker arm 43. A through rotation hole is provided on the lower side of the right part of the lower rocker arm 43. The upper outside of the first rotating shaft 32 is rotatably installed in the rotation hole. At least one positioning screw hole is provided at intervals up and down on the right side of the lower rocker arm 43. A positioning set screw 50 with its left end abutted against the outside of the right part of the first rotating shaft 32 is screwed in each positioning screw hole. When air enters through the air inlet hole 44, the cylinder sleeve 41 moves forward. When the cylinder sleeve 41 moves forward, it drives the lower rocker arm 43 and the first rotating shaft 32 to swing, so that the front side of the clamping finger 36 is far away from the rear side of the first positioning gripper 26. When air enters through the air outlet hole 45, the cylinder sleeve 41 moves backward. When the cylinder sleeve 41 moves backward, it drives the lower rocker arm 43 and the first rotating shaft 32 to swing, so that the front side of the clamping finger 36 is close to the rear side of the first positioning gripper 26.

[0046] According to requirements, a ring groove is provided on the outside of the sealing piston 42, and a sealing ring is installed in the ring groove, which can ensure the sealed contact between the outside of the sealing piston 42 and the inside of the cylinder sleeve 41. Through holes for passing through the central shaft 40 are provided on the front and rear end faces of the cylinder sleeve 41. An O-shaped sealing ring hermetically sleeved outside the central shaft 40 is installed in each through hole. O-shaped sealing rings are also installed on the outside of the front end and the outside of the rear end of the central shaft 40 to improve the sealing performance of the front end and the rear end of the central shaft 40. One or more front air outlets 46 and rear air outlets 47 can be evenly distributed at intervals along the circumference. The cylinder sleeve 41 can be made of two flanges fixedly installed at the front end and the rear end of the connecting sleeve. In order to facilitate the quick connection between the air inlet hole 44, the air outlet hole 45 and the air pipe, air pipe connectors 56 known in the art are installed in both the air inlet hole 44 and the air outlet hole 45.

[0047] During use, when air is ventilated into the air inlet 44, the gas enters the cylinder sleeve 41 in front of the sealing piston 42 through the air inlet 44 and the front air outlet 46. The gas pressure increases (the pressure in the cavity in front of the sealing piston 42 is greater than the pressure in the cavity behind the sealing piston 42), causing the cylinder sleeve 41 to move forward. When the cylinder sleeve 41 moves forward, it drives the lower rocker arm 43 and the first rotating shaft 32 to swing forward, so that the front side of the clamping finger 36 and the rear side of the first positioning gripper 26 move away from each other. In this way, the end of the workpiece between the clamping finger 36 and the first positioning gripper 26 can be placed in the clamping spindle 8 or the material tray. If the end of the workpiece to be processed is placed in the clamping spindle 8, after the clamping spindle 8 clamps the workpiece to be processed, the clamping finger 36 and the first positioning gripper 26 move away from each other and then release the workpiece to be processed. If the end of the workpiece is placed in the material tray, after the end of the workpiece is inserted into the material tray, the clamping finger 36 and the first positioning gripper 26 move away from each other and then release the workpiece. The clamping position of the workpiece is attached Fig.12 At the position indicated by the lead line of the middle mark 28 (first step surface 28 ), the vertically arranged workpiece (bar material) is clamped by the first step surface 28 , the rear side surface of the first positioning gripper 26 and the inclined surface of the clamping finger 36 .

[0048] When air is ventilated into the air outlet 45, the gas enters the cylinder sleeve 41 behind the sealing piston 42 through the air outlet 45 and the rear air outlet 47. The pressure of the gas increases (the pressure in the cavity in front of the sealing piston 42 is less than the pressure in the cavity behind the sealing piston 42), causing the cylinder sleeve 41 to move backward. When the cylinder sleeve 41 moves backward, it drives the lower rocker arm 43 and the first rotating shaft 32 to swing backward so that the front side of the clamping finger 36 and the rear side of the first positioning gripper 26 are close to each other, so that the clamping finger 36 and the first positioning gripper 26 can clamp and remove the workpiece in the clamping spindle 8 or in the material tray.

[0049] When the lower rocker arm 43 is swinging, the front inner wall and the rear inner wall of the lower mounting hole 31 abut against the lower rocker arm 43, so as to limit the lower rocker arm 43 and prevent the lower rocker arm 43 from swinging too much. The movable groove 48 is arranged so that when the lower rocker arm 43 swings, the two movable pins 49 on the left part of the lower rocker arm 43 respectively move in the movable grooves 48 at corresponding positions, so as to avoid the phenomenon that the lower rocker arm 43 swings unsmoothly when the cylinder sleeve 41 moves back and forth. The arrangement of the positioning top screw 50 can, on the one hand, make the first rotating shaft 32 and the lower rocker arm 43 swing synchronously, and on the other hand, adjust the initial position of the lower rocker arm 43, so as to realize the adjustment of the swing angle of the clamping finger 36, and realize the clamping operation of tools of various specifications, which is convenient to adjust and has a wide range of applications.

[0053] During use, through such a setting, the grinder and the workpiece in the processing can be isolated and protected to ensure the safety of the equipment and operators. At the same time, it can also fix the feed shell 51 to prevent the coolant or waste chips in the processing process from being discharged into the external environment and causing pollution, thereby improving the working environment.

[0054] Embodiment 8: As an optimization of the above embodiment, as shown in the attached Figure 7 , 9 As shown in Figures 10 and 11, the first driving assembly includes a linear module 63.

[0058] The front adjustment nozzle and the rear adjustment nozzle are both existing well-known technologies, such as a universal bamboo tube adjustment nozzle. During use, the angle of the coolant outflow from the front adjustment nozzle and the rear adjustment nozzle can be adjusted, so that the grinding wheel 66 and the workpiece to be ground can be cooled while the grinding debris can be washed away, thereby extending the service life of the grinding wheel 66.

[0059] The coolant in front of the grinding wheel 66 and the coolant behind it block each other, which can prevent the coolant from spraying outward, thereby improving the utilization efficiency of the coolant. At the same time, it can quickly reduce the temperature of the grinding wheel 66 when grinding the workpiece, extend the service life, and at the same time improve the flushing effect, and can quickly flush away the grinding debris to avoid affecting the grinding wheel 66.

[0060] The above technical features respectively constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
