Description

Technical Field

[0001] This invention relates to the field of automatic loading and unloading equipment, and in particular to an automatic loading and unloading device for a gear hobbing machine. Background Technology

[0002] In the field of mechanical manufacturing, the roller screw is a key transmission component, and the accuracy of its gear hobbing directly affects the operating performance of the equipment. The gear hobbing machine is the core equipment for achieving this machining. However, in the traditional gear hobbing process, the loading and unloading of roller screws has long relied on manual operation, resulting in many technical bottlenecks.

[0003] Manual loading and unloading is slow and cannot match the high-speed processing requirements of gear hobbing machines, severely restricting the improvement of production cycle time. Operators need to be in close contact with high-speed rotating machine tool parts, which poses a significant risk of mechanical injury and makes it difficult to guarantee safety. When placing workpieces manually, positional deviations are prone to occur, resulting in fluctuations in processing accuracy and directly affecting product consistency. At the same time, long-term reliance on manual labor not only increases labor costs, but also makes it difficult to achieve 24-hour continuous production due to the limitation of manual operation time, thus restricting the improvement of large-scale production efficiency.

[0023] Please see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the automatic loading and unloading device for a gear hobbing machine provided in an embodiment of the present invention; Figure 2 for Figure 1 The structural diagram of region A in the middle. (See diagram below.) Figure 1 and Figure 2 As shown, this invention proposes an automatic loading and unloading device for a gear hobbing machine. The automatic loading and unloading device 10 includes a pusher loading machine 11, a feeding mechanism 12, a six-axis robot, a gear hobbing machine 14, and a machine base 15. The pusher loading machine 11, the six-axis robot, and the gear hobbing machine 14 are all mounted on the machine base 15. The feeding mechanism 12 is positioned above the pusher loading machine 11. The pusher loading machine 11 includes a material box 111, a sliding table, a positioning plate assembly, and a pushing mechanism. The sliding table, the positioning plate assembly, and the pushing mechanism are all located within the material box 111. The sliding table is positioned at the bottom of the material box 111 and is inclined towards the positioning plate assembly. The inlet end of the positioning plate assembly abuts against the outlet end of the sliding table, and the outlet end of the positioning plate assembly abuts against the inlet end of the feeding mechanism. After the workpiece to be processed on the sliding table rolls into the positioning plate assembly, it moves towards the feeding mechanism under the drive of the pushing mechanism. The feeding mechanism 12 includes a linear vibrating feeder and a rotating mechanism 121. The linear vibrating feeder is provided with a material channel 122 extending along its length. The discharge end of the material channel 122 abuts against the feed end of the rotating mechanism 121. The workpiece to be processed, which is conveyed to the material channel 122, is moved to the rotating mechanism 121 under the drive of the linear vibrating feeder. After receiving the workpiece, the rotating mechanism 121 drives it to switch from a horizontal state to a vertical state. The six-axis robot includes a robot body 131 and a gripper 132. When the workpiece is switched to a vertical state, the gripper 132 of the six-axis robot picks up the workpiece and conveys it to the gear hobbing machine 14 for processing.

[0024] In this embodiment, the pusher feeder 11 includes a material box 111, a sliding table, a positioning plate assembly, and a pushing mechanism. The material box 111 serves as a bearing component to accommodate the workpieces (roller screws). The sliding table, the positioning plate assembly, and the pushing mechanism are all disposed within the material box 111. The sliding table is located at the bottom of the material box 111 and is inclined towards the positioning plate assembly. The inlet end of the positioning plate assembly abuts against the outlet end of the sliding table, and the outlet end of the positioning plate assembly abuts against the inlet end of the feeding mechanism. After a large number of workpieces are poured into the sliding table, due to the inclination of the sliding table towards the positioning plate assembly, the workpieces automatically roll towards the positioning plate assembly. After the workpieces roll into the positioning plate assembly, they are guided by the positioning plate assembly and the pushing mechanism... Driven by the feed mechanism, the feed mechanism 12 moves towards the feeding mechanism. The feeding mechanism 12 includes a linear vibratory feeder and a rotating mechanism 121. The linear vibratory feeder is provided with a material channel 122 extending along its length. The discharge end of the material channel 122 abuts against the feed end of the rotating mechanism 121. The linear vibratory feeder is fixedly installed below the material channel 122 and cooperates with the material channel 122 to drive the workpiece to be processed along the material channel 122 to the rotating mechanism 121 through linear vibration. After receiving the workpiece, the rotating mechanism 121 drives it to switch from a horizontal state to a vertical state. The six-axis robot includes a robot body 131 and a gripper 132. When the workpiece is switched to a vertical state, the gripper 132 of the six-axis robot accurately grips the workpiece and transports it to the gear hobbing machine 14 for processing.

[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, the positioning plate assembly includes multiple positioning plates 112, each of which is inclined away from the sliding table and arranged in a stepped manner along the inner sidewall of the material box 111.

[0026] In this embodiment, the positioning plate assembly includes multiple positioning plates 112, each of which is inclined away from the sliding table and arranged in a stepped manner along the inner sidewall of the material box 111. After the workpiece rolls from the sliding table into the first positioning plate 112, it will naturally adhere to the sidewall of the positioning plate 112 due to its own gravity, thus avoiding disorderly sliding. The stepped arrangement creates a height difference between adjacent positioning plates 112. With the driving action of the pushing mechanism, the workpiece can be pushed upward to the next level positioning plate 112. After being pushed step by step, the workpiece is finally conveyed to the feeding mechanism 12.

[0027] In one embodiment, such as Figure 1 and Figure 2As shown, the pushing mechanism includes multiple pushing plates 113 and a pushing drive component corresponding to each pushing plate 113. The pushing drive component is used to drive the pushing plate 113 to rise and fall. A pushing plate 113 is provided between each two adjacent positioning plates 112. Under the drive of its corresponding pushing drive component, each pushing plate 113 pushes the workpiece to be processed upward to the next level positioning plate 112 along the step rising direction. After being pushed step by step, the workpiece to be processed is conveyed to the feeding mechanism 12.

[0028] In this embodiment, the pushing mechanism includes multiple pushing plates 113 and a pushing drive component corresponding to each pushing plate 113. The pushing drive component is used to drive the corresponding pushing plate 113 to move up and down. A pushing plate 113 is provided at the gap between two adjacent positioning plates 112. Under the drive of its corresponding pushing drive component, each pushing plate 113 pushes the workpiece to be processed on the current positioning plate 112 upward to the next level positioning plate 112 along the step-up direction (towards the feeding mechanism 12). After being pushed step by step, the workpiece to be processed is finally transported to the feeding mechanism 12.

[0029] Each of the pusher drive components includes a pusher cylinder, a guide shaft, and a linear bearing. The output end of the pusher cylinder is connected to the corresponding pusher plate 113. The guide shaft is inclined, with its inclination angle matching that of the positioning plate 112. The linear bearing is sleeved on the guide shaft and fixedly connected to the corresponding pusher plate 113, used to cooperate with the guide shaft to achieve precise guidance during the lifting and lowering of the pusher plate 113, ensuring the smooth movement of the pusher plate 113. Each pusher drive component works in coordination with the corresponding pusher plate 113: when the pusher plate 113 rises under the drive of the pusher cylinder, it can push the workpiece above it upwards to the next level positioning plate 112 along the step-up direction; when the pusher plate 113 descends and resets, the cooperation between the linear bearing and the guide shaft prevents offset, ensuring the accuracy of the next push action. Through step-by-step orderly pushing, the workpiece is finally conveyed to the feeding mechanism 12.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, a baffle 123 is provided on the side of the material channel 122 away from the positioning plate assembly; a stop 124 is provided at the end of the material channel 122 near the rotating mechanism 121, the stop 124 is located above the material channel 122, and is used to block the workpiece to be processed that does not move in a straight line along the material channel 122; an inclined slide 114 is provided on the material box 111, the inclined slide 114 is located below the stop 124, and is used to guide the workpiece to be processed blocked by the stop 124 back to the material slide table.

[0031] In this embodiment, the feed channel 122 is aligned and abuts against the final pusher plate 113 in height, which can accurately receive the workpiece to be processed conveyed by the pusher plate 113 and ensure that the workpiece to be processed enters the feed channel 122 smoothly. A baffle 123 is provided on the side of the feed channel 122 away from the positioning plate assembly, which can prevent the workpiece to be processed from shifting to the side and constrain its directional movement along the length direction of the feed channel 122. A stop block 124 is provided above the end of the feed channel 122 near the rotating mechanism 121. The stop block 124 is used to intercept the skewed workpiece that does not move along a straight trajectory, so as to prevent it from entering the rotating mechanism 121 and causing abnormal posture. An inclined slide 114 is provided on the material box 111 below the stop block 124. The workpiece to be processed blocked by the stop block 124 can slide down along the inclined slide 114 and flow back to the slide table to re-enter the feeding process. This design ensures conveying accuracy through baffles 123 and blocks 124, and also enables the recycling of workpieces by means of inclined slides 114. This reduces material waste and ensures that the workpieces entering the rotating mechanism 121 have a uniform posture, providing a stable basis for the subsequent precise grasping by the six-axis robot.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the rotating mechanism 121 includes a fixture and a rotary cylinder for driving the fixture to rotate. The fixture is provided with a receiving groove adapted to the workpiece to be processed.

[0033] In this embodiment, the rotating mechanism 121 includes a fixture and a rotary cylinder for driving the fixture to rotate. The fixture is provided with a receiving groove adapted to the workpiece to be processed. The receiving groove is used to temporarily support the workpiece to be processed to ensure that the workpiece to be processed does not fall off when the fixture rotates, and to facilitate subsequent gripping by the six-axis robot.

[0034] In one embodiment, such as Figure 1 and Figure 2 As shown, a photoelectric sensor is provided above the fixture to detect whether the workpiece to be processed has been fed into the receiving groove.

[0035] In this embodiment, a photoelectric sensor is provided above the fixture to detect whether the workpiece to be processed is fed into the receiving groove. When the photoelectric sensor detects that the workpiece to be processed is fed into the receiving groove, it triggers the rotary cylinder to start, driving the fixture to rotate 90°, smoothly switching the horizontally placed workpiece to a vertical state. At this time, the gripper 132 of the six-axis robot accurately grasps the workpiece to be processed in the vertical state and transfers it to the gear hobbing machine 14. After the photoelectric sensor detects that the workpiece to be processed has been taken out, it triggers the rotary cylinder to return to its original position, preparing for the feeding of the next workpiece to be processed.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamp 132 includes a fixed plate 163, a first pneumatic gripper 161, a first cylinder for driving the first pneumatic gripper 161 to open and close, a second pneumatic gripper 162, and a second cylinder for driving the second pneumatic gripper 162 to open and close. The driving end of the robot body 131 is connected to one side of the fixed plate 163, and the other side of the fixed plate 163 is provided with the first pneumatic gripper 161 and the second pneumatic gripper 162.

[0037] In this embodiment, the first pneumatic gripper 161 is used to grip the workpiece to be processed: after the rotary cylinder turns the workpiece to be processed into a vertical state, the six-axis robot moves to the fixture, the first pneumatic gripper 161 grips the workpiece to be processed, and then transfers it to the gear hobbing machine 14 and places it on the workpiece table of the gear hobbing machine 14, where the gear hobbing machine 14 processes the workpiece to be processed; the second pneumatic gripper 162 is used to grip the processed workpiece: after the workpiece is processed, the second pneumatic gripper 162 takes it out, and at the same time, the first pneumatic gripper 161 simultaneously places a new workpiece to be processed into the workpiece table, realizing continuous operation of the processing flow.

[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, a first magnetic switch is installed on the first cylinder, and a second magnetic switch is installed on the second cylinder.

[0039] In this embodiment, a first magnetic switch is installed on the first cylinder to detect the opening and closing state of the first pneumatic gripper 161. A second magnetic switch is installed on the second cylinder to detect the opening and closing state of the second pneumatic gripper 162. The movement of the robot body 131 is coordinated according to the opening and closing states of the first and second pneumatic grippers 161 and 162 to ensure the continuity and accuracy of the automated process.

[0040] In one embodiment, such as Figure 1 and Figure 2 As shown, a plurality of compression springs are provided inside the fixing plate 163. The compression springs are installed on both sides of the first pneumatic gripper 161 and the second pneumatic gripper 162 respectively, and the two ends of the compression springs elastically abut against the fixing plate 163 and the pneumatic gripper respectively.

[0041] In this embodiment, the compression spring is installed on both sides of the first pneumatic gripper 161 and the second pneumatic gripper 162. The two ends of the compression spring are elastically abutting against the fixed plate 163 and the pneumatic gripper, respectively, forming an elastic support structure. When the pneumatic gripper performs a gripping or releasing action, the compression spring can buffer the action of the pneumatic gripper, ensuring that the workpiece maintains a stable posture during the transfer to the gear hobbing machine 14 or during the removal process, thus ensuring the reliability of automated operation.

[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the machine base 15 is provided with a feeding frame 151 for collecting and storing processed parts.

[0043] In this embodiment, after the second pneumatic gripper 162 removes the processed workpiece from the workpiece table, the robot body 131 drives the clamp 132 to move above the unloading frame 151, and the second pneumatic gripper 162 opens to release the workpiece, allowing it to fall smoothly into the unloading frame 151.
