TECHNICAL FIELD

[0001] The application relates to the field of titanium alloy processing equipment, in particular to a moving tool mounting device of a titanium alloy processing special machine tool. BACKGROUND

[0002] Titanium alloy is a material with high strength, light weight and corrosion resistance, which is widely used in aerospace, military, medical and other fields. These application fields have very high requirements for material performance, and the excellent performance of titanium alloy makes it the only choice. However, the processing of titanium alloy is difficult, mainly reflected in its high hardness, poor thermal conductivity and other aspects, which brings great challenges to processing equipment and technology. In order to ensure efficient and safe processing of titanium alloy, special designed machine tools and tools are needed to meet the specific processing requirements. In the existing titanium alloy processing process, the common tool mounting method is usually that the operator manually installs the tool on the spindle or tool holder, and then fastens it using a wrench or other tools. Although this manual tool mounting method is simple and intuitive, it has many inconveniences in actual operation. For example, when the operator manually mounts the tool, he is easy to be injured by contacting the sharp part of the machine tool or the tool, which increases the operation risk. In addition, the manual tool mounting process is relatively cumbersome and time-consuming, which leads to low tool changing efficiency and affects the overall production efficiency. The existing manual tool mounting method not only has safety hazards, but also seriously affects the tool changing efficiency, which cannot meet the needs of modern industry for efficient and automated processing. Therefore, it is urgent to develop a tool mounting device that can improve the safety and efficiency of tool changing to meet the special requirements of titanium alloy processing.

[0028] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "provided", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] This application discloses a moving tool mounting device for a special machine tool for titanium alloy machining.

[0030] like Figure 1 As shown, the moving tool mounting device of a special machine tool for titanium alloy machining includes a mounting base 1, a drive cylinder 2, a slide table 3, and a robotic arm 4. The drive cylinder 2 is mounted on the mounting base 1, which is equipped with a guide rail 5. A guide block 6 is mounted on the lower end face of the slide table 3 and slidably connected to the guide rail 5. The piston rod of the drive cylinder 2 is fixedly connected to the lower end face of the slide table 3. The robotic arm 4 is mounted on the slide table 3 and is equipped with a clamping mechanism. This device achieves rapid tool changing through automation, improving the safety and efficiency of tool changing.

[0031] Mounting base 1 is used to support and fix other components. Mounting base 1 can be made of cast iron or stainless steel, which has high strength and stability. The guide rail 5 set on mounting base 1 can be a linear guide rail 5 or a ball screw guide rail 5.

[0032] The drive cylinder 2 is the power source that propels the slide table 3. It can be either pneumatically driven or hydraulically driven. Pneumatically driven cylinders offer advantages such as fast response and low cost, making them suitable for most applications. Hydraulically driven cylinders, on the other hand, provide greater driving force and higher precision, making them suitable for applications requiring high tool changing accuracy. The piston rod of the drive cylinder 2 is fixedly connected to the lower end face of the slide table 3, which can be achieved through bolts or welding to ensure the reliability and stability of force transmission.

[0033] The robotic arm 4 is a key component for the automatic gripping and placement of tools. It can be a multi-joint robotic arm or a parallelogram linkage mechanism.

The buffer cylinder 9 piston rods are oppositely arranged, and the buffer block 8 can be pressed against the buffer cylinder 9 piston rods with the movement of the sliding table 3. This design can effectively absorb the impact energy of the sliding table 3 during movement, reducing mechanical vibration and noise.

[0037] The buffer block 8 can be made of rubber or polyurethane material, which has good elasticity and shock absorption performance. The shape of the buffer block 8 can be designed as a cylinder, a cuboid or other geometric shapes according to actual needs, so as to facilitate installation and fixation. The installation position of the buffer block 8 can be at any side of the sliding table 3, or can be adjusted according to actual work needs. The contact surface of the buffer block 8 and the buffer cylinder 9 can be designed as a plane or a curved surface. The plane contact surface can provide stable buffering effect, and the curved surface contact surface can gradually slow down when the sliding table 3 approaches the buffer cylinder 9, reducing the impact force.

The locking structure 10 is provided with a plurality of locking structures 10, and the plurality of locking structures 10 are dispersedly installed on the circumferential part of the lower end of the mechanical hand 4. This design can ensure the firm installation of the mechanical hand 4 on the sliding table 3, and improve the stability and reliability of the device.

[0039] As shown in Figure 2 The locking structure 10 includes a locking seat 101, a limiting ring 102 and an elastic sheet 103. The locking seat 101 is installed on the sliding table 3, which can be fixed by bolts or welding, etc., to ensure the stability of the installation. The locking seat 101 is provided with a locking groove 1011. The shape of the locking groove 1011 can be designed as a circle, a square or other geometric shapes according to actual needs, so as to facilitate installation and fixation. The upper end side wall of the locking groove 1011 is provided with an internal thread, and the lower end of the limiting ring 102 is provided with an external thread. The locking seat 101 is installed on the locking seat 101 by cooperating the external thread with the internal thread provided on the inner side wall of the locking groove 1011.

[0040] The locking rod 104 is arranged on the base of the mechanical arm 4, passes through the limiting ring 102, and can be clamped by rotating the limiting ring 102 to extrude the elastic sheet 103. The elastic sheet 103 can be made of spring steel or stainless steel, and has good elasticity and fatigue resistance. The elastic sheet 103 is arranged in several, and the several elastic sheets 103 are evenly arranged on the circumferential part of the locking groove 1011, so that the uniform distribution of clamping force can be ensured. The abutting block 1031 is arranged on the outer side wall of the upper end of the elastic sheet 103, the outer side wall of the abutting block 1031 is inclined outward from top to bottom, the lower end of the limiting ring 102 is provided with the abutting groove 1021, the shape of the abutting groove 1021 corresponds to the abutting block 1031, so that when the limiting ring 102 is rotated, the abutting block 1031 can smoothly enter the abutting groove 1021, and reliable clamping can be realized.
