Description
Technical Field
[0001] The utility model relates to the technical field of speed reducer processing equipment, in particular to an automatic processing and feeding device for a speed reducer end cover. Background Art
[0002] The speed reducer end cover is an important component in the speed reducer, and its function is to ensure the overall sealing performance of the speed reducer housing. During the processing of the speed reducer end cover, processes such as cutting and grinding are required. In order to meet the large-scale production requirements, in the prior art, the speed reducer end cover is usually clamped by a three-jaw chuck to achieve automatic feeding. However, the existing feeding device has the following problems: First, the three-jaw chuck not only needs to clamp the speed reducer end cover before processing, but also needs to clamp the speed reducer end cover after processing. Due to factors such as cutting and grinding, the dimensions of the speed reducer end cover before and after processing will inevitably change. However, the existing feeding device usually only uses the same three-jaw chuck to clamp, which may result in insufficient clamping force of the three-jaw chuck on the speed reducer end cover or excessive clamping force leading to surface wear of the speed reducer end cover; Second, after long-term use, the three-jaw chuck will inevitably have a certain amount of wear, resulting in the inability of the three-jaw chuck to completely clamp the speed reducer end cover. In addition, the cost of replacing the jaw elements of the three-jaw chuck is also relatively high. Summary of the Invention
[0003] In order to solve the above problems, the utility model provides an automatic processing and feeding device for a speed reducer end cover that can avoid wear of the speed reducer end cover during clamping, ensure that the speed reducer end cover can be clamped, and can reduce the maintenance cost.
[0004] Technical solution of the utility model: An automatic processing and feeding device for a reducer end cover, comprising a device base, a first sliding base connected to the device base, a second sliding base slidably connected to the first sliding base, a connecting shaft movably connected to the second sliding base, a connecting base fixedly connected to the connecting shaft, a first hydraulic three-jaw chuck connected to the connecting base, a second hydraulic three-jaw chuck connected to the connecting base, a first hydraulic cylinder for driving the first sliding base to move horizontally, a second hydraulic cylinder for driving the second sliding base to move vertically, a third hydraulic cylinder for driving the first hydraulic three-jaw chuck to open and close, a fourth hydraulic cylinder for driving the second hydraulic three-jaw chuck to open and close, a rotary motor for driving the connecting shaft to rotate, and a controller. Three jaw elements are provided on both the first hydraulic three-jaw chuck and the second hydraulic three-jaw chuck. The movement stroke of the jaw elements on the first hydraulic three-jaw chuck is less than the movement stroke of the jaw elements on the second hydraulic three-jaw chuck. The central axis of the connecting shaft forms a 45-degree angle with the central axis of the second sliding base. The central axis of the first hydraulic three-jaw chuck is perpendicular to the central axis of the second hydraulic three-jaw chuck. When the first hydraulic three-jaw chuck is in the initial state, the central axis of the first hydraulic three-jaw chuck is in the vertical state. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, and the rotary motor respectively.
[0005] Adopting the above technical solution, first, place the end cover of the speed reducer to be processed directly below the first hydraulic three-jaw chuck. Then, control the second hydraulic cylinder to drive the second sliding base to move vertically downward through the controller. Next, control the third hydraulic cylinder to drive the first three-jaw chuck to clamp the end cover of the speed reducer through the controller. Then, control the second hydraulic cylinder to drive the second sliding base to move vertically upward through the controller. Then, control the first hydraulic cylinder to drive the first sliding base to move horizontally through the controller, so that the end cover of the speed reducer moves to the processing station. When the processing work is completed, control the rotating motor to drive the connecting shaft to rotate 180 degrees through the controller. Since the central axis of the connecting shaft forms a 45-degree angle with the central axis of the second sliding base, and the central axis of the first hydraulic three-jaw chuck is perpendicular to the central axis of the second hydraulic three-jaw chuck, the positions of the first hydraulic three-jaw chuck and the second hydraulic three-jaw chuck will be interchanged. Then, clamp the processed end cover of the speed reducer with the second hydraulic three-jaw chuck. Then, control the first hydraulic cylinder and the second hydraulic cylinder to drive the first sliding base and the second sliding base to move respectively through the controller, so that the processed end cover of the speed reducer is discharged. Since the movement stroke of the jaw element on the first hydraulic three-jaw chuck is smaller than the movement stroke of the jaw element on the second hydraulic three-jaw chuck, the size of the end cover of the speed reducer that the first hydraulic three-jaw chuck can clamp is larger than the size of the end cover of the speed reducer that the second hydraulic three-jaw chuck can clamp, that is, the sizes of the end covers of the speed reducer before and after processing. This can ensure that the end cover of the speed reducer can be clamped during feeding and discharging. At the same time, it can avoid the wear of the end cover of the speed reducer due to excessive clamping force. Further setting of the present utility model: A rubber pad is provided on the inner wall of the jaw element, and the rubber pad is adapted to the cross-sectional shape and size of the jaw element.
[0006] Adopting the above technical solution, since a rubber pad is provided on the inner wall of the jaw element, and the rubber pad is made of rubber material, the rubber material has good flexibility, wear resistance and anti-slip performance, which can further ensure that the first hydraulic three-jaw chuck and the second hydraulic three-jaw chuck clamp the end cover of the speed reducer. At the same time, it further avoids the wear of the end cover of the speed reducer during the feeding process.
[0007] Further setting of the present utility model: The rubber pad is provided with a first threaded hole, the jaw element is provided with a second threaded hole, and the rubber pad and the jaw element are connected by a fixing bolt, and the fixing bolt is adapted to the shapes and sizes of the first threaded hole and the second threaded hole respectively.
[0008] Adopting the above technical solution, since the rubber pad and the jaw element are connected by a fixing bolt, when the rubber pad is severely worn, the fixing bolt can be removed from the jaw element, and then a new rubber pad can be replaced, which can greatly reduce the maintenance cost.
[0009] Further setting of the present utility model: The rubber pad is provided with countersunk holes, and the countersunk holes are coaxially arranged with the first threaded holes.
[0010] Adopting the above technical solution, since the rubber pad is provided with countersunk holes, when the fixing bolts fix the rubber pad on the jaw element, the end of the fixing bolts can be prevented from contacting the reducer end cover, further avoiding wear on the reducer end cover during the feeding process.
[0011] Further setting of the present utility model: The rubber pad is provided with a plurality of anti-slip stripes evenly distributed on the rubber pad.
[0012] Adopting the above technical solution, since the rubber pad is provided with a plurality of anti-slip stripes evenly distributed on the rubber pad, the anti-slip performance of the rubber pad can be further improved, thereby further ensuring that the first hydraulic three-jaw chuck or the second hydraulic three-jaw chuck can clamp the reducer end cover during the feeding process.

Detailed Embodiment
[0016] Such as Figure 1-2As shown in the figure, an automatic processing and feeding device for a reducer end cover includes an equipment base 1, a first sliding base 2 connected to the equipment base 1, a second sliding base 3 slidably connected to the first sliding base 2, a connecting shaft 4 movably connected to the second sliding base 3, a connecting base 5 fixedly connected to the connecting shaft 4, a first hydraulic three-jaw chuck 6 connected to the connecting base 5, a second hydraulic three-jaw chuck 7 connected to the connecting base 5, a first hydraulic cylinder 8 for driving the first sliding base 2 to move horizontally, a second hydraulic cylinder 9 for driving the second sliding base 3 to move vertically, a third hydraulic cylinder 10 for driving the first hydraulic three-jaw chuck 6 to open and close, a fourth hydraulic cylinder 11 for driving the second hydraulic three-jaw chuck 7 to open and close, a rotating motor 12 for driving the connecting shaft 4 to rotate, and a controller 13. Three jaw elements 14 are provided on both the first hydraulic three-jaw chuck 6 and the second hydraulic three-jaw chuck 7. The movement stroke of the jaw element 14 on the first hydraulic three-jaw chuck 6 is less than the movement stroke of the jaw element 14 on the second hydraulic three-jaw chuck 7. The central axis of the connecting shaft 4 forms a 45-degree angle with the central axis of the second sliding base 3. The central axis of the first hydraulic three-jaw chuck 6 is perpendicular to the central axis of the second hydraulic three-jaw chuck 7. When the first hydraulic three-jaw chuck 6 is in the initial state, the central axis of the first hydraulic three-jaw chuck 6 is in the vertical state. The controller 13 is electrically connected to the first hydraulic cylinder 8, the second hydraulic cylinder 9, the third hydraulic cylinder 10, the fourth hydraulic cylinder 11, and the rotating motor 12 respectively.
[0017] First, place the reducer end cover to be processed directly below the first hydraulic three-jaw chuck 6. Then, control the second hydraulic cylinder 9 through the controller 13 to drive the second sliding base 3 to move vertically downward. Next, control the third hydraulic cylinder 10 through the controller 13 to drive the first three-jaw chuck to clamp the reducer end cover. Then, control the second hydraulic cylinder 9 through the controller 13 to drive the second sliding base 3 to move vertically upward. Then, control the first hydraulic cylinder 8 through the controller 13 to drive the first sliding base 2 to move horizontally, so that the reducer end cover moves to the processing station. When the processing work is completed, control the rotating motor 12 through the controller 13 to drive the connecting shaft 4 to rotate 180 degrees. Since the central axis of the connecting shaft 4 forms a 45-degree angle with the central axis of the second sliding base 3, and the central axis of the first hydraulic three-jaw chuck 6 is perpendicular to the central axis of the second hydraulic three-jaw chuck 7, the positions of the first hydraulic three-jaw chuck 6 and the second hydraulic three-jaw chuck 7 will be interchanged. Then, clamp the processed reducer end cover with the second hydraulic three-jaw chuck 7. Then, control the first hydraulic cylinder 8 and the second hydraulic cylinder 9 respectively through the controller 13 to drive the first sliding base 2 and the second sliding base 3 to move, so that the processed reducer end cover is discharged. Since the movement stroke of the jaw element 14 on the first hydraulic three-jaw chuck 6 is smaller than the movement stroke of the jaw element 14 on the second hydraulic three-jaw chuck 7, the size of the reducer end cover that the first hydraulic three-jaw chuck 6 can clamp is larger than the size of the reducer end cover that the second hydraulic three-jaw chuck 7 can clamp, that is, the sizes of the reducer end covers before and after processing. This can ensure that the reducer end cover can be clamped during feeding and discharging. At the same time, it can avoid the reducer end cover from being worn due to excessive clamping force. A rubber pad 15 is provided on the inner wall of the jaw element 14, and the rubber pad 15 is adapted to the cross-sectional shape and size of the jaw element 14.
[0018] Since a rubber pad 15 is provided on the inner wall of the jaw element 14, and the rubber pad 15 is made of rubber material, the rubber material has good flexibility, wear resistance and anti-slip performance, which can further ensure that the first hydraulic three-jaw chuck 6 and the second hydraulic three-jaw chuck 7 clamp the reducer end cover. At the same time, it can further avoid the reducer end cover from being worn during the feeding process.
[0019] The rubber pad 15 is provided with a first threaded hole 16, the jaw element 14 is provided with a second threaded hole 17, and the rubber pad 15 and the jaw element 14 are connected by a fixing bolt 18. The fixing bolt 18 is adapted to the shapes and sizes of the first threaded hole 16 and the second threaded hole 17 respectively.
[0020] Since the rubber pad 15 and the jaw element 14 are connected by the fixing bolt 18, when the rubber pad 15 is severely worn, the fixing bolt 18 can be removed from the jaw element 14 and then a new rubber pad 15 can be replaced, which can greatly reduce the maintenance cost. The rubber pad 15 is provided with a countersunk hole 19 which is coaxially arranged with the first threaded hole 16.
[0021] Since the rubber pad 15 is provided with a countersunk hole 19, when the fixing bolt 18 fixes the rubber pad 15 on the jaw element 14, it can prevent the end of the fixing bolt 18 from contacting the reducer end cover, and further avoid the wear of the reducer end cover during the feeding process.
[0022] The rubber pad 15 is provided with a plurality of anti-slip stripes 20 evenly distributed on the rubber pad 15. Since the rubber pad 15 is provided with a plurality of anti-slip stripes 20 evenly distributed on the rubber pad 15, the anti-slip performance of the rubber pad 15 can be further improved, so as to further ensure that the first hydraulic three-jaw chuck 6 or the second hydraulic three-jaw chuck 7 can clamp the reducer end cover during the feeding process.
