Description

Technical Field

[0001] The present invention belongs to the technical field of tool changing in tool magazines, and particularly relates to a tool changing device for a turntable type lathe bed with spindle linkage in a tool magazine. Background Art

[0002] Tool changing with a spindle-linked turntable tool magazine is a commonly used tool changing method in modern CNC equipment such as machining centers. It mainly includes a tool magazine turntable, usually in a disc shape, with multiple tool holders evenly distributed on it for storing various tools. The tool magazine turntable is driven by a motor or a hydraulic system and can perform a rotational movement to rotate the required tool to the tool changing position. The spindle is the core component of the machine tool, used for installing the tool and driving the tool for cutting. During the tool changing process, the spindle needs to complete operations such as loosening, clamping the tool, and exchanging the tool with the tool magazine. The tool changing manipulator is generally installed between the spindle and the tool magazine, and its main function is to grasp and transfer the tool. It has multiple degrees of freedom and can perform fast and accurate movements to complete the operations of taking out the tool from the tool magazine and installing it into the spindle, and putting the tool on the spindle back into the tool magazine. The control system is responsible for coordinating the actions of various components such as the tool magazine, the spindle, and the tool changing manipulator to ensure the accurate and efficient progress of the tool changing process. The control system is usually integrated with the CNC system of the machine tool and can execute corresponding tool changing operations according to the tool changing instructions in the machining program.

[0003] When the existing spindle-linked turntable tool magazine changes tools, it is necessary to take out the tool on the spindle and the tool in the turntable tool magazine, exchange their positions, and then put them into the spindle and the tool magazine respectively. Since the tool on the spindle has just been used, chips and other impurities are likely to remain on the tool. If it is directly put into the tool magazine without cleaning at this time, it is easy for impurities to enter the tool magazine. And if the tool in the tool magazine is directly put into the spindle for use without cleaning, the impurities remaining on the tool are likely to affect the machining accuracy.

[0009] In one example, a storage cavity is provided inside the rotating seat. The upper surface of the rotating seat is concave. A plurality of through grooves are provided on the upper surface of the rotating seat, and the through grooves communicate with the storage cavity. Suction assemblies are provided below both of the rotating seats.

[0010] In one example, the suction assembly includes vertical rods which are fixedly connected to the rotating seats. The vertical rods penetrate downward through the cross plate.

A pipeline is communicated between the side wall of the circular cylinder and the rotating seat, and the pipeline is located between the sealing plate and the piston. A filter screen is fixedly connected to the side wall of the storage cavity on the rotating seat.

[0011] In one example, a fixed pipe is fixedly connected between the side wall of the circular cylinder and the piston. Check valves are installed on both the fixed pipe and the pipeline.

Detailed implementation manners

[0026] In order to more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the specification drawings.

[0027] As Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a mounting base 1. A lifting device is arranged on the mounting base 1. One side of the lifting device is fixedly connected to a bracket 2. One end of the bracket 2 is provided with a turret tool magazine 3. A plurality of fixing claws are arranged on the turret tool magazine 3, and tools are fixed on the fixing claws. One side of the mounting base 1 is provided with a spindle device 4. The lower part of the bracket 2 is fixedly connected to an equipment box 5. A tool changing component 6 is arranged on the equipment box 5. A cleaning component 7 is arranged on the tool changing component 6. The cleaning component 7 includes a driving part. A cross plate 74 is installed on the driving part. Two rotating seats 75 are rotatably connected to the upper surface of the cross plate 74. The upper surface of the rotating seat 75 is provided with bristles. The rotating seat 75 is located below the tool changing component 6. The turret tool magazine 3 is a spindle linkage type tool magazine. When a tool change is required, it descends under the action of the lifting device at this time and approaches the spindle device 4. At the same time, the turret tool magazine 3 drives the tool changing component 6 to descend together. When the turret tool magazine 3 approaches the spindle device 4, the tool changing component 6 is located between the spindle device 4 and the turret tool magazine 3 at this time. After the tool changing component 6 grabs the tool on the spindle device 4 and the tool to be changed on the turret tool magazine 3, the tool changing component 6 exchanges the positions of the tool on the spindle device 4 and the tool on the turret tool magazine 3, and inserts the tool to be changed into the spindle device 4. The used tool is placed back into the turret tool magazine 3. During the process of the tool changing component 6 removing the tool on the spindle device 4 and the tool to be changed on the turret tool magazine 3, the rotating seat 75 on the cleaning component 7 rotates, and the bristles clean the tools on the tool changing component 6, reducing the chip residue on the tools, making the tools cleaner, and avoiding problems such as machining dimension deviation and increased surface roughness caused by impurities such as residual chips on the tools, which affect the machining accuracy and workpiece quality.

[0028] As Figures 1 to 6As shown, the tool changing assembly 6 includes a mounting plate 61, which is fixedly connected to the equipment box 5. The upper surface of the mounting plate 61 is fixedly connected with an electric push rod 62. The telescopic rod of the electric push rod 62 is fixedly connected with a support plate 63. A rotating rod 64 is rotatably connected to the support plate 63. The rotating rod 64 penetrates downward through the equipment box 5. A tool changer 65 is fixedly connected to the outer side of the rotating rod 64. The lower surface of the support plate 63 is fixedly connected with a driving motor. The main shaft of the driving motor is fixedly connected with a gear. A toothed ring is fixedly connected to the outer side of the rotating rod 64. The toothed ring meshes with the gear. Before tool changing, the cleaning assembly 7 and the tool changing assembly 6 are horizontally arranged between the turret tool magazine 3 and the spindle equipment 4 for avoidance, so as to prevent the cleaning assembly 7 and the tool changing assembly 6 from being knocked when the turret tool magazine 3 moves up and down. When tool changing, at this time, the driving motor drives the tool changer 65 to rotate. The tool changer 65 is an existing device and usually has two tool holders with opposite directions. One of the two tool holders on the tool changer 65 holds the tool in the turret tool magazine 3, and the other holds the tool on the spindle equipment 4. Then, the electric push rod 62 pushes the support plate 63 downward, and the two tools are taken out from the spindle equipment 4 and the turret tool magazine 3 through the tool changer 65. Then, the driving motor drives the tool changer 65 to rotate, and the two tools are changed in position. The electric push rod 62 pulls the support plate 63 upward, and the tools are respectively inserted into the spindle equipment 4 and the turret tool magazine 3 to complete tool changing. During the tool changing process, the turret tool magazine 3 rotates for tool changing and tool placing.

[0029] As Figures 2 to 6 shown, the driving part in the cleaning assembly 7 includes a fixing plate 71, which is fixedly connected to the equipment box 5. The upper surface of the fixing plate 71 is fixedly connected with a second motor 72. The main shaft of the second motor 72 is fixedly connected with a round rod 73. The round rod 73 penetrates downward through the rotating rod 64 and is rotatably connected to the rotating rod 64. The round rod 73 is fixedly connected with a cross plate 74. When in use, the cross plate 74 is driven by the second motor 72 to make the rotating seat 75 be respectively located below the spindle equipment and the turret tool magazine 3. When the tool changer 65 grabs the tool and descends to extract the tool, the lower part of the tool extends into the brush hairs, and the brush hairs contact the tool. The rotating seat 75 rotates, so that the brush hairs clean the tool, brush off the residual chips and other impurities on the tool, and make the tool cleaner. Then, the tool changer 65 drives the tool to rotate, exchanges positions, and then rises to insert the tool into the corresponding position.

[0030] As Figure 6 with Figure 7As shown, a storage cavity 8 is provided inside the rotating seat 75. The upper surface of the rotating seat 75 is concave. Multiple through grooves are provided on the upper surface of the rotating seat 75, and the through grooves communicate with the storage cavity 8. Suction components 9 are provided below both rotating seats 75. The suction component 9 includes a vertical rod 91, and the vertical rod 91 is fixedly connected to the rotating seat 75. The vertical rod 91 penetrates downward through the cross plate 74. The lower ends of the vertical rods 91 are fixedly connected to a support plate 92. Multiple circular cylinders 93 are fixedly connected to the upper surface of the support plate 92. A sealing plate 94 is fixedly connected inside the circular cylinder 93. A sliding rod 95 is slidably connected to the sealing plate 94. The lower end of the sliding rod 95 is fixedly connected to a piston 96. The piston 96 is slidably connected to the circular cylinder 93. A first spring is fixedly connected between the piston 96 and the circular cylinder 93. A pipeline 97 is communicated between the side wall of the circular cylinder 93 and the rotating seat 75. The pipeline 97 is located between the sealing plate 94 and the piston 96. A filter screen is fixedly connected to the side wall of the storage cavity 8 on the rotating seat 75. A fixed pipe is fixedly connected to the side wall of the circular cylinder 93 between the sealing plate 94 and the piston 96. One-way valves are installed on both the fixed pipe and the pipeline 97. A circular through groove is provided on the side wall of the circular cylinder 93 near the bottom of the circular cylinder 93. The upper ends of the sliding rods 95 are fixedly connected to spherical blocks 10. Multiple arc-shaped blocks 11 are provided on the lower surface of the cross plate 74. Both sides of the arc-shaped block 11 are provided with inclined surfaces. All the arc-shaped blocks 11 are arranged in an annular array. When the rotating seat 75 rotates to brush and clean the tool, the rotating seat 75 drives the circular cylinder 93 to rotate. When the spherical block 10 at the upper end of the circular cylinder 93 contacts and gradually slides onto the inclined surface of the arc-shaped block 11, the sliding rod 95 slides downward, pushing the piston 96 to descend. The piston 96 moves away from the sealing plate 94, and suction is generated between the piston 96 and the sealing plate 94. At this time, the one-way valve on the pipeline 97 opens, and the one-way valve on the fixed pipe closes. Through the pipeline 97, suction is generated in the storage cavity 8 on the rotating seat 75. When the brush bristles clean the tool, due to the action of suction, the chips on the tool enter the concave surface of the rotating seat 75 downward, and chips and other impurities enter the storage cavity 8, so that the impurities are collected, avoiding the impurities from splashing everywhere and being difficult to clean. When the spherical block 10 separates from the arc-shaped block 11, the one-way valve on the pipeline 97 closes, and the one-way valve on the fixed pipe opens, avoiding the appearance of blowing force in the pipeline 97 and the storage cavity 8 when the piston 96 resets, resulting in the debris in the storage cavity 8 being blown out. At the same time, by providing multiple circular cylinders 93 and multiple arc-shaped blocks 11, the number of arc-shaped blocks 11 is more than that of the circular cylinders 93. At any time, there is contact between the spherical block 10 and the inclined surface of the arc-shaped plate, so that suction can always exist in the storage cavity 8 to suck the impurities, improving the collection efficiency of the impurities.

[0031] As Figure 7 with Figure 8As shown in the figure, the lower end of the round rod 73 is fixedly connected to the threaded rod 12. The lower surface of the cross plate 74 is rotatably connected to the rotating ring 13. The lower surface of the rotating ring 13 is fixedly connected to two first belt pulleys 14. The outer side of the threaded rod 12 is provided with a circular tube 15. The inner side of the circular tube 15 is provided with balls 16. The balls 16 cooperate with the threaded rod 12. The outer side of the circular tube 15 is provided with protrusions. The circular tube 15 penetrates through the first belt pulley 14 and is slidably connected to the first belt pulley 14. The lower surfaces of both support plates 92 are fixedly connected to second belt pulleys 17. The second belt pulleys 17 are connected to the first belt pulleys 14 by belts. The cross plate 74 is slidably connected to a plurality of support rods 19. The support rods 19 penetrate through the cross plate 74. The upper ends of the support rods 19 are fixedly connected to fixing rings 18. A second spring is fixedly connected between the fixing rings 18 and the cross plate 74. The lower ends of the support rods 19 are fixedly connected to circular rings 20. The circular rings 20 are rotatably connected to the circular tube 15. When the tool changer 65 grabs the tool and descends, the lower surface of the tool changer 65 presses down the fixing ring 18. The fixing ring 18 and the circular ring 20 descend. The circular ring 20 pushes the circular tube 15 downward. Under the action of the balls 16 and the threaded rod 12, the circular tube 15 spirally descends. When the circular tube 15 descends, it drives the first belt pulley 14 to rotate, and drives the support plates 92 and the rotating seats 75 on both sides to rotate through the belt, so as to clean the descending tool, which is more convenient to use.

[0032] Working principle: The turret magazine 3 is a main shaft linkage type tool magazine. When a tool change is required, it descends under the action of the lifting device at this time and approaches the main shaft device 4. At the same time, the turret magazine 3 drives the tool changing assembly 6 to descend together. When the turret magazine 3 approaches the main shaft device 4, the tool changing assembly 6 is located between the main shaft device 4 and the turret magazine 3 at this time. The drive motor drives the tool changer 65 to rotate. One of the two tool holders on the tool changer 65 clamps the tool in the turret magazine 3, and the other clamps the tool on the main shaft device 4. Then the electric push rod 62 pushes the support plate 63 to descend, and the two tools are taken out from the main shaft device 4 and the turret magazine 3 through the tool changer 65. The lower part of the tool extends into the bristles, and the bristles contact the tool. The lower surface of the tool changer 65 presses down the fixing ring 18. The fixing ring 18 and the circular ring 20 descend. The circular ring 20 pushes the circular tube 15 downward. Under the action of the balls 16 and the threaded rod 12, the circular tube 15 spirally descends. When the circular tube 15 descends, it drives the first belt pulley 14 to rotate, and drives the support plates 92 and the rotating seats 75 on both sides to rotate through the belt. When the spherical block 10 at the upper end of the circular cylinder 93 contacts and gradually slides onto the inclined surface of the arc block 11, the sliding rod 95 slides downward, pushing the piston 96 to descend. The piston 96 moves away from the sealing plate 94, and a suction force is generated between the piston 96 and the sealing plate 94. At this time, the one-way valve on the pipeline 97 opens, and the one-way valve on the fixed pipe closes. Through the pipeline 97, a suction force is generated in the storage cavity 8 on the rotating seat 75. When the bristles clean the tool, due to the suction force, the chips on the tool enter the concave surface of the rotating seat 75 downward, and the chips and other impurities enter the storage cavity 8, so as to collect the impurities.
