[0020] See also Figure 1-8 , Example

[0021] The present embodiment provides a turntable device for realizing precise transmission of workpieces to be processed, which includes a rotating disk 1 capable of indexing rotation, the rotating disk is provided with a plurality of bins 11 for placing the workpieces to be processed, the rotating disk 6 is installed on the turntable base, and the turntable base is provided with a driving part for driving the rotating disk 6 to rotate at a predetermined angle to realize indexing rotation.

[0022] Specifically, first is the turntable base, which includes a bottom plate 2 horizontally connected to the workbench 1, two side plates 3 longitudinally symmetrically supported on the bottom plate, and an intermediate support plate 4 and a top fixed plate 5 connected to the two side plates 3, and the intermediate support plate 4 is provided with a driving part for driving the rotating disk 6 to rotate.

[0023] In more detail, the driving unit includes a turntable servo motor 7, a hollow rotating platform reducer 8 and a connecting flange 9. The hollow rotating platform reducer 8 is supported on the middle supporting plate 4. The input end of the hollow rotating platform reducer 8 is connected to the turntable servo motor 7 that can provide power. The output end of the hollow rotating platform reducer 8 is connected to the connecting flange 9. The connecting flange 9 is installed on the top fixed plate 5. A rotating disk 6 for loading the workpiece is installed on the connecting flange 9. The driving unit drives the rotating disk 6 to rotate in an indexing manner, driving the workpiece 10 on the rotating disk 6 to rotate in an indexing manner according to a predetermined angle, and is transmitted from one position to the next position.

[0024] When the system starts working, the turntable servo motor 7 receives a start signal, and the turntable servo motor 7 drives the rotating disk 6 to start rotating through the hollow rotating platform reducer 8, and gradually reaches a predetermined rotation speed to ensure the smooth transfer of the workpiece 10 between the various silos. The hollow rotating platform reducer can increase the torque and precise division, thereby realizing high-precision rotation and positioning control, and then drives the rotating disk to rotate according to a predetermined angle, realizes precise positioning, and stops the rotating disk at a predetermined angle position.

[0025] Next is the material bin, and a plurality of the material bins 11 are provided, and the plurality of material bins 11 are arranged to be evenly spaced along the circumferential edge of the rotating disk 6 .

[0026] Two arc-shaped limiting rings 12 are installed on the top fixing plate 5. The two arc-shaped limiting rings 12 are relatively arranged along the outer peripheral wall of the rotating disk 6 to form an annular limiting space, which can limit the workpiece 10 in the feeding bin when the rotating disk rotates.

[0027] The arc-shaped limiting ring 12 ensures the stability and accuracy of the workpiece 10 during the machining process, and also reduces the machining error caused by the deviation or shaking of the workpiece 10 .

[0028] On the basis of the above structure, the two arc-shaped limit rings 12 are both set as spaced and unconnected opening areas at the corresponding first end and second end, and the two opening areas can form corresponding processing stations to meet corresponding processing requirements.

[0029] The rotating disk 6 of this embodiment is driven by the driving part to rotate and transport in a circular manner without waiting. The workpiece 10 on the rotating disk 6 can be immediately transferred to the next position as the rotating disk 6 rotates at an indexing angle, which significantly improves the transfer efficiency of the workpiece. At the same time, the rotating disk 6 can rotate according to a predetermined angle to achieve accurate transfer of the workpiece. Example

[0030] Based on the turntable device of Example 1, this embodiment provides a high-precision gear end face grinding system for achieving end face grinding of the processed gear. It can be upgraded and modified based on an ordinary vertical machining center, and includes a workbench 1 and a turntable device arranged on the workbench.

[0031] In this embodiment, the two arc-shaped limit rings 12 form an open area at the corresponding unconnected first end intervals, and this area is set as a loading station 13. At the loading station 13, the processed gear is placed in the hopper 11 and is driven by the rotating disk 6 to move to the next position.

[0032] The two arc-shaped limit rings 12 form an open area at the corresponding second end intervals where they are not connected. This area is set as a grinding station 14. When the gear to be processed is brought to the grinding station 14, the gear end face is ground.

[0033] A material unloading station 15 is also provided on the rotating disk 6 , and the processed gear that has been ground is continuously sent to the material unloading station 15 along with the indexing transmission of the rotating disk 6 .

[0034] The above-mentioned loading station 13, grinding station 14 and unloading station 15 are arranged along the circumference of the rotating disk 6, and in the same direction of rotation as the rotating disk 6. The processed gear can pass through the loading station 13, grinding station 14 and unloading station 15 in sequence as the rotating disk 6 rotates at a scale, thereby forming continuous gear end face grinding.

[0035] Specifically, the first is the loading station 13, one side of which is provided with a loading mechanism, through which the material bin 11 on the rotating disk 6 is continuously fed with material: The feeding mechanism includes a feeding belt conveyor 16 and a sensor 17. The feeding end of the feeding belt conveyor is provided with a workpiece turnover box 18. The discharging end of the feeding belt conveyor 16 is located above the feeding station 13. The sensor 17 is also provided at the silo position of the discharging end of the feeding belt conveyor 16 for detecting whether the processed gear is delivered to the right place.

[0036] Next is the unloading station 15, which is provided with a unloading trough 19 and an unloading mechanism. The gear to be processed after the end face grinding is conveyed out of the unloading mechanism through the unloading trough 19: The unloading mechanism includes an unloading belt conveyor 20 , a feeding end of the unloading belt conveyor 20 is located below the unloading chute 19 , and a discharging end of the unloading belt conveyor 20 is connected to the workpiece turnover box 18 .

[0037] On the basis of the above structure, the grinding station 14 is provided with a clamping tool arranged close to the rotating disk for clamping and driving the processed gear to rotate, and a grinding head for grinding the end face of the processed gear. The grinding head is arranged above the grinding station 14, and the clamping tool is arranged below the grinding station.

[0038] In this embodiment, the arrangement of the rotating disk 6, the material bin 11, the loading station 13, the grinding station 14 and the unloading station 15 fully utilizes the space and power of the rotating disk 6 to achieve continuous processing.

[0039] In more detail, the grinding head includes a grinding wheel 21, a connecting mandrel 22 and a pull pin 23. The grinding wheel 21 is detachably connected to the main shaft 24 of the machining center. One end of the connecting mandrel 22 is inserted into the center hole of the grinding wheel and is connected to the grinding wheel 21 through a locking nut. The other end of the connecting mandrel 22 is connected to the main shaft 24 through the pull pin 23.

[0040] The clamping tooling includes a grinding clamping servo motor 25, a planetary reducer 26 and a toggle gear 27, wherein the input end of the planetary reducer 26 is connected to the grinding clamping servo motor 25 capable of providing power, and the output end of the planetary reducer 26 is connected to the toggle gear 27, and the toggle gear 27 is configured to enable the processed gear 28 to rotate.

[0041] Furthermore, a pad block 29 is provided at the output end of the planetary reducer 26. By adjusting the height of the pad block 29, the position of the toggle gear 27 can be accurately adjusted to ensure that the toggle gear 27 and the processed gear can be smoothly adapted and meshed. A toggle gear pressure plate 30 is provided on the top end face of the toggle gear 27. The toggle gear pressure plate 30 is used to press the toggle gear 27 to prevent it from shaking or shifting during rotation, thereby ensuring the stability of the transmission of the toggle gear 27 and thus ensuring the accuracy of the processing of the processed gear 28.

[0042] Furthermore, a groove 31 is provided on the top fixing plate 5 at the grinding station 14, and a wear-resistant block 32 for supporting the processed gear 28 is embedded in the groove 31. The top end surface of the wear-resistant block 32 is configured to contact and cooperate with the bottom end surface of the processed gear 28. The top end surface of the wear-resistant block 32 is configured to be higher than the plane where the top fixing plate 5 is located, so that the wear-resistant block 32 can effectively support the processed gear 28, while avoiding direct contact between the top fixing plate 5 and the processed gear 28, thereby reducing wear and friction.

[0043] In the actual processing, Figure 7 As shown, the top surface of the wear-resistant block 32 needs to be polished with a grinding wheel 21 to ensure that the grinding end surface of the grinding wheel is absolutely parallel to the contact surface of the processed gear, thereby ensuring the stability and processing accuracy of the processed gear during the grinding process.

[0044] The high-precision gear end surface grinding system of this embodiment can be assisted on the basis of an ordinary vertical machining center, and can achieve manual pre-preparation of materials, automatic processing by the equipment, and automatic discharge of materials. The precision and stability of the processed products are very high, which improves the processing efficiency, and is particularly reliable in terms of safe production. At the same time, it can also reduce the processing steps and reduce costs.

[0045] This processing system will not cause any additional modification to the equipment and is very easy to use. It only needs to be installed on the work surface of the vertical machining center. After removal, the equipment will be restored to an ordinary vertical machining center, achieving dual or even multi-purpose use of one machine. Example

[0046] Based on the gear high-precision end surface grinding processing system of Example 2, this embodiment provides a gear high-precision end surface grinding processing method, including the following sequential steps: S1, the processed gear in the workpiece turnover box falls into the silo at the loading station through the loading belt conveyor; S2, the sensor at the loading station detects whether the gear to be processed is in place; S3, when the sensor detects that the processed gear is in place, the rotating disk starts to rotate, driving the processed gear to rotate to the next position according to the predetermined angle indexing; S4, when the processed gear rotates to the grinding station, the shifting gear meshes with the processed gear, and then the shifting gear starts to accelerate under the drive of the grinding clamping servo motor and the planetary reducer. At this time, the processed gear will also start to rotate at the same speed. This synchronous rotation ensures that all parts of the end face of the processed gear can be evenly ground during the grinding process; S5, when the gear being processed turns to the grinding station and rotates steadily at a predetermined speed, the spindle grinding wheel will begin to descend. When the spindle grinding wheel contacts the end face of the gear being processed, the end face grinding officially begins; S6, when the gear end face grinding reaches the predetermined processing requirements, the spindle grinding wheel starts to rise to end the grinding, and at this time the grinding of one end face of the processed gear is completed; S7, then the toggle gear starts to decelerate under the control of the grinding clamping servo motor and the planetary reducer, ensuring that the toggle gear can smoothly mesh with the gear being processed and drive it to rotate during the next gear grinding operation. At the same time, the gear being processed that has completed an end face grinding process will continue to rotate to the next position driven by the rotating disk; S8, the rotating disk continues to rotate, and steps S1 to S5 are repeated; S9, the processed gear after grinding is transported to the unloading station as the rotating disk continues to rotate, and then falls into the unloading belt conveyor through the unloading chute. The unloading belt conveyor delivers the processed gear to the workpiece turnover box, and then enters the next cycle to complete the grinding of the other end face.

[0047] In the above cycle, the processed gear in the workpiece turnover box falls into the loading station through the loading belt conveyor, and falls into the next position one by one as the rotating disk rotates. When the processed gear rotates to the grinding station, the grinding process begins. After completion, it continues to be sent to the unloading station as the rotating disk rotates, and then is sent into the workpiece turnover box again through the unloading belt conveyor.

[0048] In this process, the processed gear passes through the loading station, grinding station and unloading station in sequence as the rotating disk rotates at an indexing speed, so as to form a cyclic and continuous gear end face grinding. Through the cyclic rotation and transportation of the rotating disk, there is no need to wait and the gear can be immediately transferred to the next station for processing, which significantly improves production efficiency.

[0049] During the high-precision grinding of the gear end face in this embodiment, the spindle grinding wheel 21 is set to grind in a clockwise direction, the rotating disk 6 on the workbench 1 rotates clockwise to index and transmit the processed gear, the shifting gear 27 rotates clockwise to drive the processed gear 28, and the processed gear 28 rotates counterclockwise.

[0050] The beneficial effects of the high-precision gear end surface grinding system of the present invention are: Manual pre-preparation of materials, automatic processing and automatic unloading of materials by the equipment: This system allows the operator to perform simple material preparation work before processing, and then the processing process can be completed automatically without manual intervention. After the processing is completed, the system can automatically remove the finished product from the workbench, reducing the tediousness of manual handling, and also avoiding product damage or misoperation caused by human factors, greatly improving processing efficiency, and realizing automation and intelligence; The rotating disk can rotate in indexing mode. The high-precision grinding head and reliable clamping fixture work together with the rotating disk to ensure that the processed products have extremely high precision and stability, meeting the high-precision processing requirements. The processing path is optimized, unnecessary processes are reduced, processing efficiency is further improved, and production costs are reduced; No additional modification is required. The system does not require any additional modification to the vertical machining center. It can be simply installed on the work surface. It is easy to install and disassemble, which greatly reduces the installation cost and time. One machine has multiple uses. When you need to restore the vertical machining center to its normal state, you only need to easily disassemble the system, realizing the flexibility and versatility of the equipment.
