Description

Technical Field

[0001] This application relates to the field of metal processing equipment technology, and in particular to a CNC machine tool loading device for machining cylinder end caps. Background Technology

[0002] CNC machine tools are automated machine tools equipped with a program control system. They integrate mechanical, automation, computer, and microelectronic technologies to solve the problem of machining complex, precise, and small-batch parts. They are flexible and high-efficiency automated machine tools. CNC machine tools have advantages such as strong adaptability to the workpiece, high machining accuracy, stable machining quality, high productivity, high reliability, and improved working conditions.

[0003] In the cylinder manufacturing process, CNC machine tools are used to process metal parts to obtain the cylinder housing and end caps. For the shaping of the end caps, because the resulting end caps are relatively small, the metal raw materials used to make them are also relatively small. Typically, they are stacked to increase the amount of metal raw material in a single loading operation. However, in the stacking method, a push-drive mechanism is needed to move each end cap upwards so that a robot can grasp and load them. But after all the stacked metal raw materials have been removed, it is necessary to wait for the push-drive mechanism to reset before new metal raw materials can be stacked and placed at the loading position, resulting in a long loading waiting time, which needs improvement. Utility Model Content

[0004] Based on this, this application provides a CNC machine tool loading device for cylinder end cover processing, which can greatly reduce the waiting time for loading, thereby improving the overall operation efficiency of end cover shaping processing.

[0005] The CNC machine tool loading device for machining cylinder end caps provided in this application adopts the following technical solution:

[0006] A loading device for a CNC machine tool used for machining cylinder end caps, disposed on the surface of the machine tool assembly of the CNC machine tool, comprising:

[0007] The worktable is rotatably mounted on the machine tool assembly, and the machine tool assembly contains a rotary drive assembly for driving the worktable to rotate.

[0008] The placement mechanism is provided in multiple sets, and each set of placement mechanisms is evenly arranged around the central axis of the worktable. The placement mechanism includes a limiting rod and a workstation base plate. There are multiple limiting rods, and each limiting rod is set on the worktable. A placement area is formed between all the limiting rods, and the workstation base plate is movably set in the placement area.

[0009] Push mechanism; The surface of the machine tool assembly is provided with a loading station. The push mechanism is located on the machine tool assembly and below the loading station. When the rotary drive assembly is activated, each group of placement mechanisms moves to the loading station in sequence. The push mechanism is used to force the work plate at the loading station to move upward.

[0010] Optionally, the workstation substrate is provided with multiple limiting grooves, and the number of limiting grooves and limiting rods are matched. Each limiting rod is respectively inserted into each limiting groove to realize that the workstation substrate is naturally placed in the placement area.

[0011] Optionally, the pushing mechanism includes a pushing drive fixed to the worktable and a pushing block connected to the movable end of the pushing drive. When the placement mechanism moves to the loading station, the worktable base plate is partially aligned with the pushing block.

[0012] Optionally, each limiting rod is slidably connected to the worktable, and the sliding direction of each limiting rod is directly opposite to the center line of the workstation base plate; an adjustment mechanism for adjusting the position of each limiting rod is provided among the limiting rods.

[0013] Optional adjustment mechanisms include:

[0014] A rotating shaft passes through and is rotatably connected to the workbench plate, and a transmission gear is fixedly connected to the bottom end of the rotating shaft.

[0015] The drive assembly is located at the bottom of the worktable. The drive assembly is used to cooperate with each transmission gear to achieve the same direction and speed of rotation of each rotating shaft.

[0016] An adjustment plate is located at the top of the rotating shaft. The adjustment plate has multiple arc-shaped holes, and each limiting rod passes through a corresponding arc-shaped hole. The distance from the arc-shaped hole to the center of the adjustment plate gradually changes from one end of the arc-shaped hole to the other end.

[0017] Optionally, the drive assembly includes a gear ring plate, a drive gear, and a drive motor. The gear ring plate is rotatably mounted on the bottom of the worktable, and the outer peripheral wall of the gear ring plate is provided with an outer gear ring that meshes with each of the transmission gears. The drive motor is fixed to the worktable, the drive gear is fixedly connected to the output end of the drive motor, and the inner peripheral wall of the gear ring plate is provided with an inner gear ring that meshes with the drive gear.

[0018] Optionally, the surface of the machine tool assembly is fixed with multiple mounting seats, each of which is fitted with freely rolling balls, and the worktable plate normally rests against the balls.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When the rotary drive assembly of this application is activated, it enables each group of placement mechanisms to move sequentially to the loading station. At this time, the placement mechanism at the loading station has multiple metal raw materials to be processed stacked on it. Through the pushing mechanism, each metal raw material can be forced to gradually move upward to a specific height so that the robot arm of the CNC machine tool can easily grasp it and realize the loading. While the loading station is loading, new metal raw materials to be processed can be placed on the placement mechanisms in other positions, which can greatly reduce the loading waiting time and improve the overall operation efficiency of end cap forming processing.

[0021] 2. The cooperation between the limiting rod and the limiting groove allows the workstation board to be naturally placed in the placement area. The workstation board can be pulled directly upwards, which facilitates the disassembly, cleaning or maintenance of the workstation board and is beneficial to the normal use of the feeding device.

[0022] 3. By controlling the operation of the drive component to force the adjustment plate to rotate, the relative positions of each limit rod can be changed, thereby adjusting the size of the placement area to accommodate the shaping and processing of cylinder end caps of different sizes, thus improving the adaptability and compatibility of CNC machine tools.

[0023] 4. By controlling the operation of the drive motor to force the drive gear to rotate, the drive gear can drive the gear ring plate to rotate circumferentially around the central axis of the worktable. Then, through the meshing of the outer gear ring with each transmission gear, the transmission gear can be forced to rotate circumferentially, thereby driving the adjustment plate to rotate to change the size of the placement area, so as to adapt to the shaping and processing of cylinder end caps of different sizes.

[0024] 5. The ball bearings provide support for the worktable, and the point contact between the worktable and the ball bearings helps to reduce frictional resistance between them, so that the rotary drive assembly can smoothly drive the worktable to rotate circumferentially.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0032] This application discloses a CNC machine tool loading device for machining cylinder end caps. The device is installed on the surface of the machine tool assembly 1 of the CNC machine tool and is mainly used for loading and placing the metal raw materials to be processed, so that the robot arm of the CNC machine tool can grab the metal raw materials to be processed and transfer them to the machining center of the CNC machine tool to complete the shaping processing of the metal raw materials, thereby producing cylinder end caps of the required shape.

[0033] Reference Figure 1 A CNC machine tool loading device for machining cylinder end caps includes a worktable 2, a placement mechanism 4, and a pushing mechanism 3. The worktable 2 is rotatably mounted on the surface of a machine tool assembly 1. Multiple mounting seats 11 are fixed on the surface of the machine tool assembly 1, and all mounting seats 11 are equidistantly arranged around the central axis of the worktable 2. Each mounting seat 11 has a freely rolling ball 12 embedded on its top. The bottom of the outer edge of the worktable 2 can abut against the ball 12, which can provide auxiliary support for the worktable 2 and reduce the frictional resistance of the worktable 2, thus facilitating the smooth rotation of the worktable 2.

[0034] The machine tool assembly 1 contains a rotary drive assembly (not shown in the figure), the output end of which is connected to the worktable 2 to drive the worktable 2 to rotate circumferentially around its own central axis. It should be noted that the rotary drive assembly can be configured with a motor, reducer, and various transmission stages, but this is not the focus of this case and will not be elaborated here.

[0035] The placement mechanism 4 is provided in multiple sets, each set of placement mechanism 4 is set on the surface of the worktable 2, and all placement mechanisms 4 are equidistantly arranged around the central axis of the worktable 2. (Refer to...) Figure 2The placement mechanism 4 includes a limiting rod 41 and a workstation base plate 42. There are multiple limiting rods 41. In this embodiment, the number of limiting rods 41 is set to 3. Each limiting rod 41 is equidistant from the worktable 2. All the limiting rods 41 together form a placement area 43 for placing the workstation base plate 42.

[0036] The workstation substrate 42 has multiple limiting grooves 421. The number of limiting grooves 421 is equal to the number of limiting rods 41. Each limiting rod 41 can pass through each limiting groove 421, so that the workstation substrate 42 can be naturally placed in the placement area 43. After the workstation substrate 42 is placed in the placement area 43, the metal raw materials to be processed can be stacked on top of the workstation substrate 42, so that each metal raw material is stably placed in the placement area 43.

[0037] The machine tool assembly 1 has a loading station 13 on its surface, allowing the robot arm to grab metal raw materials at the loading station 13. It should be noted that when the rotary drive assembly moves to rotate the worktable 2, each group of placement mechanisms 4 can move sequentially to the loading station 13. A support rod 6 is rotatably mounted at the center of the worktable 2 surface. In this embodiment, the support rod 6 passes through the inside of the machine tool assembly 1 and is fixedly connected to it, so that the angle remains fixed when the worktable 2 rotates. A laser positioner 61 is fixed to the support rod 6. The laser positioner 61 is always facing the loading station 13 and is used to detect the presence of metal raw materials.

[0038] The push mechanism 3 is located on the machine tool assembly 1 and is located directly below the loading station 13. When the placement mechanism 4 moves to the loading station 13, the push mechanism 3 can be controlled to force the station plate 42 to gradually move upward, so that the metal material at the top among the metal materials stacked on the station plate 42 can be pushed upward to a height that can be irradiated by the laser positioner 61, so that the laser positioner 61 can detect the presence of the metal material and send a signal to control the movement of the robot.

[0039] Specifically, the pushing mechanism 3 includes a pushing drive 31 fixed inside the machine tool assembly 1 and a pushing block 32 connected to the movable end of the pushing drive 31. The worktable 2 has multiple clearance slots 22, the number of which is equal to the number of placement mechanisms 4. Each clearance slot 22 is respectively positioned directly below each group of placement mechanisms 4. When the placement mechanism 4 is located at the loading station 13, the pushing block 32 can be directly opposite the clearance slot 22, and the workstation base plate 42 can also be partially directly opposite the pushing block 32. During operation, by controlling the movement of the pushing drive 31, the pushing block 32 can pass through the clearance slot 22 and abut against the workstation base plate 42, thereby forcing the workstation base plate 42 and the various metal raw materials placed on the workstation base plate 42 to gradually move upward. In this embodiment, the pushing drive 31 can be a cylinder, a hydraulic cylinder, or an electric push rod, etc., selectively configured according to actual needs.

[0040] Reference Figure 3 The sliding connection between the limiting rod 41 and the worktable 2 is as follows: a sliding block 411 is fixedly connected to the bottom of the limiting rod 41, and at the same time, refer to... Figure 2 The surface of the workbench 2 is provided with a sliding groove 21, and the sliding block 411 is installed in the sliding groove 21 and can move along the extension direction of the sliding groove 21. It should be noted that in this embodiment, the extension direction of the sliding groove 21 is directly opposite to the center line of the workstation plate 42, that is, the sliding direction of the limiting rod 41 is directly opposite to the central axis of the workstation plate.

[0041] Back Figure 2 Each limiting rod 41 is provided with an adjustment mechanism 5 for adjusting the position of the limiting rod 41; see details below. Figure 4 The adjustment mechanism 5 includes a rotating shaft 51, an adjustment plate 52, and a drive assembly. The rotating shaft 51 passes through the worktable 2 and is rotatably connected to the worktable 2. The adjustment plate 52 is coaxially fixed to the top of the rotating shaft 51. It is worth mentioning that when the workstation base plate 42 is placed in the placement area 43, the workstation base plate 42 can naturally abut against the adjustment plate 52 under its own gravity, and the workstation base plate 42 can maintain coaxiality with the adjustment plate 52.

[0042] The adjusting plate 52 has multiple vertically penetrating arc-shaped holes 521, all of which are equidistant from the center of the adjusting plate 52. Each limiting rod 41 passes through a corresponding arc-shaped hole 521. In this embodiment, the distance between the arc-shaped hole 521 and the center of the adjusting plate 52 gradually changes from one end of the arc-shaped hole 521 to the other. Therefore, when the adjusting plate 52 rotates, the inner wall of the arc-shaped hole 521 abuts against the limiting rod 41, forcing the limiting rod 41 to slide, thereby adjusting the size of the placement area 43 and enabling stable placement of metal raw materials of different sizes.

[0043] A transmission gear 53 is fixedly connected to the bottom end of the limiting rod 41. The drive assembly is located below the worktable 2, and the drive assembly can cooperate with each transmission gear 53 to achieve the same speed and direction of rotation of each rotating shaft rod 51. (See also...) Figure 5 The drive assembly includes a gear ring plate 54, a drive gear 56 and a drive motor 55. The gear ring plate 54 is rotatably mounted on the bottom of the worktable 2 and the gear ring plate 54 and the worktable 2 are coaxial. The outer peripheral wall of the gear ring plate 54 is provided with an integrally formed outer gear ring 541, and each transmission gear 53 meshes with the outer gear ring 541 for transmission.

[0044] The drive motor 55 is fixedly mounted on the bottom of the workbench 2, while the drive gear 56 is fixedly connected to the output end of the drive motor 55. The inner circumferential wall of the gear ring plate 54 is provided with an integrally formed internal gear ring 542, which meshes with the drive gear 56 for transmission. Based on this, by controlling the operation of the drive motor 55, the drive gear 56 can drive the gear ring plate 54 to rotate circumferentially, thereby forcing each transmission gear 53 to rotate in the same direction and at the same speed, so as to achieve synchronous adjustment of each placement area 43, making it more convenient to use.

[0045] The implementation principle of the CNC machine tool loading device for machining cylinder end caps in this application embodiment is as follows:

[0046] By controlling the rotation drive assembly, each group of placement mechanisms 4 is moved sequentially to the loading station 13. At this time, the placement mechanism 4 at the loading station 13 has multiple metal raw materials to be processed stacked on it. The pushing mechanism 3 can force each metal raw material to gradually move upward to a specific height so that the robot arm of the CNC machine tool can easily grab it and realize the loading. While the loading station 13 is loading, new metal raw materials to be processed can be placed on the placement mechanism 4 in other positions, which can greatly reduce the loading waiting time and improve the overall operation efficiency of end cap shaping.

[0047] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
