Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a tool holder assembly and a high-speed umbrella-type tool magazine. Background Art

[0002] A tool magazine is a device used to store tools in a machine tool. When machining a workpiece, the tool magazine provides tools of corresponding specifications to meet different machining requirements.

[0003] In order to improve the machining efficiency and meet the requirements of automatic tool change, a tool clamping assembly is usually arranged on the tool disc. The tool clamping assembly is used to clamp the tool. When the tool needs to be removed, the tool disc drives the tool clamping assembly and the tool to rotate to one side of the tool pick-up device. After unlocking the tool clamping assembly, the tool pick-up device removes the tool. However, during the rotation of the tool disc, the tool is likely to automatically disengage from the tool clamping assembly. For example, the publication number is CN110449957A, and the application name is a rotary tool change device and its tool change method, which includes a tool disc, a self-locking tool holder, an anti-drop tool block, a rotating shaft, a spring, a tool release top block and a tool release cylinder. The middle part of the anti-drop tool block is rotatably installed on the self-locking tool holder through the rotating shaft. One end of the anti-drop tool block clamps the tool, and the other end of the anti-drop tool block is connected to the self-locking tool holder through a spring. The spring applies a thrust to one end of the anti-drop tool block, and the other end of the anti-drop tool block clamps the tool. When the tool needs to be released, the tool release cylinder pushes the tool release top block towards the anti-drop tool block. The anti-drop tool block compresses the spring and releases the tool. Since centrifugal force is generated during the rotation of the tool disc, especially when the tool disc rotates around a horizontal line, the anti-drop tool block generates different magnitudes of centrifugal force at the high point and the low point of the tool disc. The possibility of the anti-drop tool block rotating by itself around the rotating shaft is extremely high, and automatic tool release is likely to occur, resulting in high safety risks.

[0050] Such as Figure 1 And Figure 2As shown, the present embodiment provides a high-speed umbrella-type tool magazine, which includes a mounting seat 300, a tool disc 400, a rotating drive member 500, a plurality of tool clamp assemblies 100 and an unlocking drive member 600; the tool disc 400 is rotatably mounted on the mounting seat 300; the rotating drive member 500 is fixedly mounted on the mounting seat 300, the tool disc 400 is connected to the output end of the rotating drive member 500, and the rotating drive member 500 is used to drive the tool disc 400 to rotate around the mounting seat 300; a plurality of tool clamp assemblies 100 are installed at intervals around the periphery of the tool disc 400; the unlocking drive member 600 is fixedly mounted on the mounting seat 300, and when the tool clamp assembly 100 is radially aligned with the unlocking drive member 600, the unlocking drive member 600 can push the pushing member toward the elastic member 5, so that the pushing portion 31 leaves the slide groove 12.

[0051] Optionally, the rotating drive member 500 is a motor and the unlocking drive member 600 is a cylinder. When it is necessary to unlock the tool 200 on a group of tool clamp assemblies 100, the motor drives the tool disc 400 to rotate, and the tool disc 400 drives the tool clamp assembly 100 to align with the cylinder. An unlocking plate is provided at the output end of the cylinder, and the cylinder drives the unlocking plate to press against the tool clamp assembly 100, thereby unlocking the tool clamp assembly 100.

[0052] Optionally, the mounting base 300 is further provided with a proximity switch, and the proximity switch is used to detect the position of the unlocking plate.

[0053] like Figures 3 to 8 As shown, the tool clamp assembly 100 of this embodiment includes a tool clamp 1, a clamping member 2, a pushing member and an elastic member 5. The tool clamp 1 is provided with a clamping groove 11 and a sliding groove 12. The sliding groove 12 is connected to the clamping groove 11, and the clamping groove 11 is used to accommodate the tool 200; the clamping member 2 is movably arranged in the sliding groove 12 along a first direction; the pushing member is movably arranged in the second direction on the side of the clamping member 2 away from the clamping groove 11, and the first direction and the second direction are arranged at an angle. The pushing member includes a pushing portion 31. When the pushing portion 31 extends into the sliding groove 12, the pushing portion 31 can push the clamping member 2 to slide toward the clamping groove 11 and press the tool 200. When the pushing portion 31 leaves the sliding groove 12, the clamping member 2 can slide away from the clamping groove 11 and release the tool 200; the elastic member 5 is used to push the pushing portion 31 to extend into the sliding groove 12.

[0054] The tool holder assembly 100 of this embodiment can be applied to a high-speed umbrella-type tool magazine, and can also be applied to other devices such as a tool 200 transfer device.

[0055] In this embodiment, the elastic member 5 is a spring. When the cylinder drives the unlocking plate to press against the tool holder assembly 100, when the unlocking plate applies pressure to the pushing member, the spring is compressed, the pushing portion 31 leaves the sliding groove 12, and the clamping force of the clamping member 2 on the tool 200 disappears, and the tool 200 can be easily removed. After the external force is eliminated, the spring returns to its original state, and the spring pushes the pushing portion 31 into the sliding groove 12. The pushing portion 31 pushes the clamping member 2 against the tool 200 in the clamping groove 11 in the sliding groove 12, and the clamping member 2 clamps the tool 200 in the clamping groove 11, avoiding the phenomenon of automatic tool loosening and ensuring safety.

[0056] In this embodiment, the first direction is the tangential direction of the tool disc 400, and the second direction is the radial direction of the tool disc 400. The tool disc 400 can rotate around the vertical line or the horizontal line. When the tool disc 400 rotates around the horizontal line, the clamping member 2 generates different magnitudes of centrifugal force at the high point and the low point of the tool disc 400. However, since the clamping member 2 is arranged in the sliding groove 12 and the extending direction of the sliding groove 12 is perpendicular to the direction of the centrifugal force, the clamping member 2 will not automatically loosen the tool 200, preventing the phenomenon of automatic tool loosening.

[0057] Optionally, the central axis of the sliding groove 12 and the central axis of the pushing member are arranged at intervals, that is, the pushing member is offset to one side of the central axis of the sliding groove 12.

[0058] Optionally, the interval value between the central axis of the pushing member and the central axis of the sliding groove 12 is less than the radius of the clamping member 2. When the clamping member 2 loosens the tool 200 and returns to the inside of the sliding groove 12, the pushing member can prevent the clamping member 2 from sliding to the side of the pushing member away from the clamping groove 11. When the pushing portion 31 extends into the sliding groove 12, it can prevent the clamping member 2 from sliding in the direction away from the clamping groove 11.

[0059] Optionally, the clamping member 2 is a sphere, and the pushing portion 31 is a cone. When the pushing portion 31 extends into the sliding groove 12, the conical surface of the pushing portion 31 abuts against the spherical surface of the clamping member 2. When the pushing portion 31 leaves the sliding groove 12, the conical surface of the pushing portion 31 separates from the spherical surface of the clamping member 2.

[0060] The conical surface of the pushing portion 31 is inclined. When the pushing portion 31 gradually extends into the sliding groove 12, the pushing portion 31 pushes the clamping member 2 to gradually approach the tool 200 until the tool 200 is clamped.

[0061] Optionally, a limiting portion 13 is provided at the port of the sliding groove 12 close to the clamping groove 11. The limiting portion 13 is used to limit the clamping member 2 from separating from the sliding groove 12 on the side close to the clamping groove 11.

[0062] Optionally, a first plugging member 6 is detachably installed at the port on the side of the sliding groove 12 away from the clamping groove 11. When the first plugging member 6 is removed, the clamping member 2 can slide into or out of the sliding groove 12 from the port on the side of the sliding groove 12 away from the clamping groove 11, and the first plugging member 6 can prevent dust and impurities from entering the sliding groove 12 from the port on the side of the sliding groove 12 away from the clamping groove 11.

[0063] Optionally, the tool holder 1 is provided with a guiding groove 14 which is communicated with the sliding groove 12. The pushing member and the elastic member 5 are both arranged in the guiding groove 14. The guiding groove 14 extends along the radial direction of the tool disc 400, and the guiding groove 14 is used to guide the pushing member and the elastic member 5 to prevent the pushing member or the elastic member 5 from deviating from the preset position.

[0064] Optionally, a second plugging member 7 is arranged at one end of the guiding groove 14. The elastic member 5 is located between the second plugging member 7 and the pushing member. A limiting member 8 is arranged at the other end of the guiding groove 14, and the limiting member 8 is used to limit the pushing member from detaching from the tool holder 1.

[0065] Optionally, the pushing member includes an unlocking pin 3 and a guiding pin 4. The unlocking pin 3 and the guiding pin 4 are separately arranged. The unlocking pin 3 is located between the guiding pin 4 and the elastic member 5, and a pushing portion 31 is arranged on the unlocking pin 3.

[0066] After the air cylinder drives the unlocking plate to press against the guiding pin 4, the guiding pin 4 pushes the unlocking pin 3 to press the elastic member 5 tightly. The guiding pin 4 contacts and collides with the unlocking plate. The guiding pin 4 is a consumable and is convenient for replacement.

[0067] Optionally, the guiding groove 14 includes a first accommodating groove 141, a second accommodating groove 142 and a third accommodating groove 143 which are sequentially communicated. The first accommodating groove 141 is communicated with the sliding groove 12. The elastic member 5 is accommodated in the first accommodating groove 141.
