Description

Technical Field

[0001] This application relates to the field of equipment for machining electric spindles of presses, and in particular to a feeding mechanism for machining electric spindles of presses. Background Technology

[0002] In the machining and production of pressurized electromechanical spindles, the loading process is a crucial step to ensure efficient and precise machining. Currently, the industry mostly uses traditional robotic arm-type loading mechanisms for loading pressurized electromechanical spindles. These mechanisms work by controlling the multi-degree-of-freedom movement of the robotic arm through a pre-programmed sequence to grasp and transport the electromechanical spindle.

[0003] However, this traditional robotic arm-type loading mechanism has many technical drawbacks in practical applications. First, the structural design of the robotic arm results in a relatively fixed motion trajectory. For pressurized electromechanical spindles of different specifications and processing positions, frequent adjustments to program parameters are often required, making operation cumbersome and prone to errors. Second, the gripping component of the robotic arm is usually a single clamping structure. When dealing with workpieces such as pressurized electromechanical spindles that require high dimensional precision and have easily damaged surfaces, it is difficult to accurately control the gripping force. Insufficient force may cause the workpiece to slip, while excessive force may cause scratches on the workpiece surface, seriously affecting product quality.

[0004] To address this problem, a feeding mechanism for machining a pressure-bearing electromechanical spindle is invented. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of traditional robotic arm-type feeding mechanisms in the prior art, such as cumbersome operation, low grasping accuracy, high manufacturing cost, and limited working range, and to provide a feeding mechanism for machining pressure electromechanical spindles that is simple in structure, convenient to operate, stable in grasping, has a wide working range, and low manufacturing cost.

[0006] The feeding mechanism for machining the pressure electromechanical spindle provided in this application adopts the following technical solution: it includes a column, a horizontal cantilever, a horizontal sliding assembly, and a gripping assembly; the horizontal cantilever is mounted on the column, the horizontal sliding assembly is slidably mounted on the horizontal cantilever, and the gripping assembly is mounted on the horizontal sliding assembly for gripping the pressure electromechanical spindle.

[0007] Optionally, the horizontal sliding assembly includes a horizontal motor, which is disposed at the end of the horizontal cantilever frame. The horizontal cantilever frame is provided with a rotatable horizontal screw, and a sliding frame is threadedly connected to the horizontal screw. The sliding frame and the horizontal cantilever frame are slidably connected.

[0008] Optionally, the column is provided with a guide groove, the horizontal cantilever can slide up and down in the guide groove, a vertical motor is provided at the top of the column, a vertical screw is provided in the guide groove, and the output end of the vertical motor is fixedly connected to the vertical screw.

[0009] Optionally, the gripping assembly includes a sliding frame, which is slidably mounted on a sliding frame. An electric telescopic rod is mounted on the sliding frame, and the output end of the electric telescopic rod is fixedly connected to the sliding frame. Gripping components are respectively mounted on both sides of the sliding frame.

[0010] Optionally, the gripping component includes two hinged rods hinged to the sliding frame and a limiting frame disposed at the bottom of the sliding frame. The two hinged rods are arranged opposite to each other. The bottom of the limiting frame is hinged with a sliding sleeve that slides with the hinged rods. When the limiting frame moves up and down, the sliding sleeve drives the two hinged rods to clamp or release the pressure electromechanical spindle.

[0011] Optionally, the bottom of the limiting frame is provided with a connecting spring, and the bottom of the connecting spring is provided with a clamping plate that can contact the main shaft of the press motor.

[0012] In summary, this application includes the following beneficial technical effects: Simple structure and easy operation: This mechanism consists of main components such as columns, horizontal cantilever frames, horizontal sliding components and gripping components. The structure is simple and the movement in all directions is achieved by a motor-driven screw. The operation process only requires controlling the motor and electric telescopic rod, without the need for complicated program debugging, which reduces the difficulty of operation.

[0013] Stable gripping and workpiece protection: The gripping component adopts a clamping method with a hinged rod and a sliding sleeve, combined with a buffer clamping design of connecting spring and clamping plate. It can automatically adapt the clamping force according to the shape of the press spindle, avoiding workpiece slippage or surface scratches, and effectively ensuring the machining quality of the press spindle.

[0014] Wide working range and strong adaptability: The horizontal and vertical movable design greatly increases the working range of this feeding mechanism, which can cover multiple processing equipment in different positions without the need to configure multiple feeding equipment, thus enhancing its adaptability to different processing scenarios.

[0015] Low manufacturing cost and easy maintenance: Compared with traditional robotic arms, this mechanism has fewer parts and a simpler structure, resulting in significantly lower manufacturing costs. At the same time, the connection relationship between each component is clear, making it easy to quickly troubleshoot and repair in case of failure, thus reducing equipment maintenance costs and downtime.

[0018] Reference Figure 1 , Figure 2 One embodiment shown is as follows: The feeding mechanism for machining the spindle of a pressure-bearing electromechanical system includes a column 1, a horizontal cantilever 2, a horizontal sliding assembly 3, and a gripping assembly 4. In this embodiment, the column 1 is placed vertically, and the horizontal cantilever 2 is distributed horizontally. One end of the horizontal cantilever 2 is fixedly connected to the middle of the side wall of the column 1 by bolts, and the length direction of the horizontal cantilever 2 is perpendicular to the vertical direction of the column 1. The horizontal sliding assembly 3 is slidably assembled through the cooperation of a slide rail and a slider. The slide rail is fixed to the lower surface of the horizontal cantilever 2 along the length direction of the horizontal cantilever 2, and the slider is welded and fixed to the inner side wall of the horizontal sliding assembly 3. The slider engages... The gripping component 4 is bolted to the bottom center of the horizontal sliding component 3 via a flange, and the gripping direction of the gripping component 4 is directly downward, perpendicular to the sliding direction of the horizontal sliding component 3. The implementation principle is as follows: when the horizontal sliding component 3 slides along the slide rail of the horizontal cantilever 2, it will drive the gripping component 4 at the bottom to move synchronously in the horizontal direction, thereby adjusting the position of the gripping component 4 on the horizontal plane, realizing the gripping of the pressure electromechanical spindle stored at different horizontal positions. After gripping, the pressure electromechanical spindle is transferred to the loading station of the processing equipment through the sliding of the horizontal sliding component 3 to complete the loading operation.

[0019] Reference Figure 3 , Figure 4 One embodiment shown is as follows: the horizontal sliding assembly 3 includes a horizontal motor 5, a horizontal screw 6, and a sliding frame 7; in this embodiment, a motor mounting base is welded to one end of the horizontal cantilever 2, the housing of the horizontal motor 5 is fixedly connected to the motor mounting base by bolts, and the output shaft of the horizontal motor 5 faces the column 1, consistent with the length direction of the horizontal cantilever 2; one end of the horizontal screw 6 is fixedly connected to the output shaft of the horizontal motor 5 by a coupling, and the other end is rotatably connected to the side wall of the horizontal cantilever 2 near the column 1 by a bearing seat, the bearing seat is fixed to the side wall of the horizontal cantilever 2 by bolts, the axis of the horizontal screw 6 is collinear with the axis of the output shaft of the horizontal motor 5, and is distributed along the length direction of the horizontal cantilever 2; the sliding frame 7 is slidably connected. A sliding connection is achieved at the bottom of the horizontal cantilever 2. A threaded hole is provided in the middle of the sliding frame 7. The horizontal screw 6 passes through the threaded hole and is threadedly engaged with the sliding frame 7. The outer periphery of the horizontal screw 6 does not contact the inner sidewall of the sliding frame 7. The implementation principle is as follows: After the horizontal motor 5 is started, its output shaft drives the horizontal screw 6 to rotate around its own axis. Since the sliding frame 7 is engaged with the horizontal screw 6 through the thread, and the rotational freedom of the sliding frame 7 is restricted by the slider and the slide rail of the horizontal cantilever 2, the rotation of the horizontal screw 6 will be converted into the linear motion of the sliding frame 7 along the length direction of the horizontal cantilever 2. This will drive the gripping component 4 connected to the bottom of the sliding frame 7 to achieve horizontal position adjustment. Furthermore, the reciprocating sliding of the sliding frame 7 can be achieved by controlling the forward and reverse rotation of the horizontal motor 5.

[0020] Reference Figure 1 , Figure 2One embodiment shown is as follows: The column 1 of the feeding mechanism for the machining of the electromechanical spindle has a guide groove 8, and also includes a horizontal cantilever 2, a vertical motor 9, and a vertical screw 10. In this embodiment, the column 1 has a cuboid structure, and a rectangular guide groove 8 is formed on one side wall along the vertical direction. The length direction of the guide groove 8 is consistent with the height direction of the column 1, and the width matches the end thickness of the horizontal cantilever 2. The end of the horizontal cantilever 2 near the column 1 is inserted into the guide groove 8, and sliding bushings are respectively provided between the upper and lower surfaces of the insertion end of the horizontal cantilever 2 and the upper and lower groove walls of the guide groove 8. The sliding bushings are fixed to the horizontal cantilever 2 by bolts, and the sliding bushings are tightly fitted with the groove wall of the guide groove 8 to achieve a sliding connection. The vertical motor 9 is fixedly installed at the center of the top end face of the column 1 by a motor bracket. The motor bracket is welded to the top of the column 1, and the output shaft of the vertical motor 9 faces directly downward, consistent with the height direction of the column 1. The vertical screw 10 is located in the guide groove 8, and its top end passes through... The vertical screw 10 is fixedly connected to the output shaft of the vertical motor 9 via a coupling. Its bottom end is rotatably connected to the bottom wall of the guide groove 8 via a bearing seat. The bearing seat is welded and fixed to the bottom wall of the guide groove 8. The axis of the vertical screw 10 is collinear with the axis of the output shaft of the vertical motor 9. A threaded hole is opened at one end of the horizontal cantilever 2 that is inserted into the guide groove 8. The vertical screw 10 passes through the threaded hole and is threadedly engaged with the horizontal cantilever 2. The implementation principle is as follows: After the vertical motor 9 is started, its output shaft drives the vertical screw 10 to rotate around its own axis. Since the horizontal cantilever 2 is engaged with the vertical screw 10 via a thread and the horizontal movement freedom of the horizontal cantilever 2 is restricted by the engagement of the sliding bushing with the guide groove 8, the rotation of the vertical screw 10 will be converted into the linear movement of the horizontal cantilever 2 along the vertical direction of the guide groove 8. This will drive the horizontal sliding component 3 and the gripping component 4 on the horizontal cantilever 2 to rise and fall synchronously, thereby adjusting the vertical height of the gripping component 4 to adapt to material storage platforms and processing equipment loading stations of different heights.

[0021] Reference Figure 1 , Figure 2One embodiment shown is as follows: the gripping assembly 4 includes a sliding frame 11, an electric telescopic rod 12, and gripping components; in this embodiment, two parallel guide rods are welded to the bottom of the sliding frame 7 along the vertical direction, and the axis of the guide rods is consistent with the vertical direction; the sliding frame 11 is a horizontally placed plate-like structure, with guide holes opened at both ends, and the two guide rods pass through the corresponding guide holes respectively. The sliding frame 11 is assembled to slide up and down through the cooperation of the guide holes and guide rods, and a certain gap is maintained between the upper surface of the sliding frame 11 and the bottom of the sliding frame 7; the electric telescopic rod 12 is vertically distributed, and its cylinder top is bolted to the center of the bottom of the sliding frame 7 through a flange. The output shaft of the electric telescopic rod 12 faces downward, and its end is fixedly connected to the center of the upper surface of the sliding frame 11 through bolts, and the axis of the electric telescopic rod 12 is parallel to the axis of the guide rods; Two gripping components are symmetrically fixed to the left and right ends of the sliding frame 11 by bolts, and the gripping directions of the two gripping components are opposite, both facing the center line of the sliding frame 11. The implementation principle is as follows: when the output shaft of the electric telescopic rod 12 extends or retracts, it will drive the sliding frame 11 to slide up and down along the vertical direction of the guide rod. During the up and down movement of the sliding frame 11, it will simultaneously drive the gripping components on both sides to move up and down. When the gripping components move to the outer periphery of the press-bearing electromechanical spindle, the action of the gripping components will clamp the press-bearing electromechanical spindle. After clamping, the electric telescopic rod 12 retracts, driving the sliding frame 11 to rise and lift the press-bearing electromechanical spindle away from the storage platform. Then, in conjunction with the lifting action of the horizontal sliding component 3 and the column 1, the press-bearing electromechanical spindle is transferred to the loading station. After that, the electric telescopic rod 12 extends, driving the sliding frame 11 to descend, and the gripping components release the press-bearing electromechanical spindle to complete the loading.

[0022] Reference Figure 1 , Figure 5One embodiment shown is as follows: the gripping component includes two hinge rods 13, a limiting frame 14, and a sliding sleeve 15; in this embodiment, hinge seats are welded to the left and right sides of the bottom of the sliding frame 7, one end of each of the two hinge rods 13 is hinged to the corresponding hinge seat through a pin, and the two hinge rods 13 are symmetrically arranged opposite each other. The hinge rods 13 can rotate around the pin in the vertical plane, and the other end of the hinge rods 13 faces downward and is inclined outward; the top of the limiting frame 14 is fixedly connected to the bottom of the sliding frame 11 by bolts, and the limiting frame 14 is located directly below the two hinge rods 13; a sliding sleeve 15 is fitted on each hinge rod 13, and the outer wall of the sliding sleeve 15 is hinged to the bottom two ends of the limiting frame 14 through a pin, and the sliding sleeve 15 can rotate around the pin and slide along the length direction of the hinge rod 13; The implementation principle is as follows: When the sliding frame 11 moves downward under the drive of the electric telescopic rod 12, it will drive the limiting frame 14 to move downward synchronously. During the downward movement of the limiting frame 14, it will pull the sliding sleeve 15 to slide downward along the hinge rod 13 through the pin. Since one end of the hinge rod 13 is fixed to the hinge seat of the sliding frame 7, the downward sliding of the sliding sleeve 15 will force the hinge rod 13 to rotate inward around the hinge seat. The free ends of the two hinge rods 13 gradually approach each other, thereby achieving the clamping of the pressure-bearing electromechanical spindle located between the two hinge rods 13. When the sliding frame 11 moves upward, the limiting frame 14 moves upward synchronously, driving the sliding sleeve 15 to slide upward along the hinge rod 13. Under the push of the sliding sleeve 15, the hinge rod 13 rotates outward around the hinge seat. The free ends of the two hinge rods 13 move away from each other, thereby relaxing the clamping of the pressure-bearing electromechanical spindle.

[0023] Reference Figure 5One embodiment shown is as follows: the gripping component further includes a connecting spring 16 and a clamping plate 17; in this embodiment, a spring mounting post is welded to the center of the bottom of the limiting frame 14, the spring mounting post is vertically distributed, and its axis is collinear with the center line of the limiting frame 14; the connecting spring 16 is sleeved on the outside of the spring mounting post, the top of the connecting spring 16 is welded and fixed to the bottom of the limiting frame 14, and the bottom is welded and fixed to the upper surface of the clamping plate 17, and when the connecting spring 16 is in its natural state, the lower surface of the clamping plate 17 is lower than the bottom end face of the limiting frame 14; the clamping plate 17 has a circular plate structure, the diameter of which is slightly smaller than the outer diameter of a common bearing electromechanical spindle, and a rubber buffer pad is pasted on the lower surface of the clamping plate 17, the lower surface of the rubber buffer pad is flat; the implementation principle is: when the limiting frame 14 moves downward with the sliding frame 11, the hinge rod 13 gradually clamps the bearing During the pressing process of the electric spindle, the clamping plate 17 first contacts the top end face of the electric spindle. As the sliding frame 11 continues to move downward, the connecting spring 16 is compressed by the limiting frame 14 and the clamping plate 17, generating an upward elastic force. This elastic force is transmitted to the top of the electric spindle through the clamping plate 17, exerting a downward clamping effect on the electric spindle. Combined with the clamping of the side wall of the electric spindle by the hinge rod 13, a double fixation of "side clamping + top pressing" is formed, preventing the electric spindle from axial movement or radial displacement during the gripping process. At the same time, the rubber buffer pad can prevent the clamping plate 17 from directly and rigidly contacting the surface of the electric spindle, preventing scratches on the surface of the electric spindle. The elastic deformation of the connecting spring 16 can also adapt to electric spindles of different heights, ensuring the clamping effect while avoiding excessive compression damage to the electric spindle.

[0024] The working principle of this device is as follows: This mechanism achieves precise feeding of the pressure-bearing electromechanical spindle through the coordinated operation of multiple components, as follows: Height adjustment: The vertical motor 9 drives the vertical screw 10 in the guide groove 8 of the column 1 to rotate. The horizontal cantilever 2 moves up and down in the vertical direction by means of the threaded engagement and the guide groove 8 limit, which drives the horizontal sliding component 3 and the gripping component 4 to adjust to the appropriate height of the material.

[0025] Horizontal displacement: The horizontal motor 5 drives the horizontal screw 6 on the horizontal cantilever 2 to rotate, and the sliding frame 7 slides horizontally by means of threaded engagement and guide rail limit, moving the gripping component 4 directly above the main shaft of the press motor.

[0026] Grasping action: The electric telescopic rod 12 extends, driving the sliding frame 11 to move down along the guide rod. The limiting frame 14 moves down synchronously, and the sliding sleeve 15 pulls the hinge rod 13 to rotate inward, clamping the side wall of the pressure electromechanical main shaft. At the same time, the clamping plate 17 first contacts the top of the pressure electromechanical main shaft, and the compression spring contracts to form upward pressure, achieving double fixation.

[0027] Transfer and loading: The electric telescopic rod 12 retracts and lifts the pressure machine main shaft. Combined with the horizontal sliding and vertical lifting actions, the pressure machine main shaft is moved above the processing station. The electric telescopic rod 12 extends, the sliding frame 11 moves up and the hinge rod 13 opens, releasing the pressure machine main shaft to complete the loading.
