[0002] In CNC machining equipment, in order to meet the needs of different machining processes, an automatic tool magazine is generally configured. The tool is clamped and fixed by the tool clamp module in the tool magazine. When the machining equipment needs to replace the tool, the tool clamp module holding the corresponding tool is moved to the tool changing position through the tool magazine to facilitate the spindle to change the tool. The tool clamp module configured on the existing tool magazine generally sets the tool clamp module on the chain link, and moves the chain under the transmission of the driving gear, so as to adjust the setting position of the tool clamp module, which is convenient for the CNC machining equipment to change the tool. However, for a larger tool magazine, a large number of tool clamp modules are required, so the chain links required are also large. Therefore, this setting method of the prior art will make the installation process very complicated, which will bring great inconvenience to production assembly and maintenance work.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] See also Figure 1 , Figure 2The utility model provides a tool clamp module compatible with chain link function, including: a tool clamp unit seat 1, clamping jaws 2 hinged on both sides of the tool clamp unit seat 1, and connecting ears 11 arranged on both sides of the tool clamp unit seat 1. Adjacent tool clamp unit seats 1 are connected by staggered overlapping connecting ears 11 and connected through connecting members 111. A driving hole 12 is arranged on one side of the clamping surface of the tool clamp unit seat 1 away from the clamping surface of the clamping jaws 2. The driving hole 12 is connected to the gear teeth of the output gear 8 arranged on the output end of the tool magazine 6 driving motor 7, and the gear teeth are engaged in the driving hole 12. During installation, the gear teeth of the output gear 8 are embedded into the drive hole 12, and the connecting ear 11 is passed through the connecting piece 111 to realize the connection between the adjacent tool clamp unit seats 1, and the tool clamp unit seat 1 is connected and surrounded and used as a chain link. In this way, the tool clamp unit seat 1 is compatible with the chain function, and the tool clamp unit seat 1 is directly driven to move by the output gear 8, thereby reducing the number of components used in the tool magazine 6 as a whole, saving costs, and facilitating the assembly and maintenance of the tool clamp module.

[0019] In some embodiments, the connecting ears 11 are equidistantly distributed on the side of the tool clamp unit seat 1 in the vertical direction, and the gap between adjacent connecting ears 11 is greater than or equal to the thickness of the connecting ears 11. The connecting ears 11 of adjacent tool clamp unit seats 1 are mutually embedded in the gaps between the connecting ears 11. The connecting ears 11 of adjacent tool clamp unit seats 1 are staggered to ensure that after the tool clamp unit seats 1 are connected and surrounded to form a chain, the clamping surfaces of each group of tool clamp unit seats 1 are on the same plane, avoiding the deviation of the clamping jaw position affecting the tool change work.

[0020] The connecting member 111 is a pin or a bolt, so as to ensure the stability of the connection state between adjacent tool clamp unit seats 1 while providing a rotation pair between adjacent tool clamp unit seats 1, so as to facilitate movement along the edge of the tool magazine 6 and turning along the arc edge of the tool magazine 6.

[0021] See also Figure 1 , Figure 3In some embodiments, a clamping jaw block 3 is slidably provided on the tool clamping unit seat 1, and the two sides of the clamping jaw block 3 are respectively in contact with the clamping jaws 2 on the two sides of the tool clamping unit seat 1, and the clamping jaws 2 are provided with C-shaped grooves 21 corresponding to the clamping jaw block 3, and the C-shaped grooves 21 are included on the outside of the clamping jaw block 3. The tool clamping unit seat 1 is provided with a reset unit, and the reset unit is connected to the clamping jaw block 3 or the clamping jaw 2. Under normal conditions, the reset unit generates a thrust for the clamping jaw block 3 or the clamping jaw 2, so that the clamping jaw 2 generates a clamping force, thereby clamping and fixing the tool 5. The front end of the clamping jaw 2 is an inclined surface inclined inward, and the clamping surface of the clamping jaw 2 is an arc surface. When inserting the tool 5, the outer side surface of the clamping part of the tool 5 contacts the inclined surface of the front end of the clamping jaw 2, and as the tool 5 moves toward the tool clamping unit seat 1, the outer side surface of the tool 5 pushes the inclined surface, thereby pushing the clamping jaw 2 to rotate around the hinge position, thereby separating the clamping jaws 2 on both sides, making it easier for the tool 5 to enter the clamping part of the clamping jaw 2. After the tool 5 completely enters the clamping position of the clamping jaw 2, the clamping jaw 2 clamps and fixes the tool 5 under the push of the reset unit.

[0022] When the tool 5 needs to be taken out, the tool 5 is pulled outward, and the outer side surface of the clamping portion of the tool 5 moves along the arc surface of the clamping surface of the clamping jaw 2, and the clamping jaw 2 is opened outward to facilitate the removal of the tool 5. When the tool 5 is completely separated from the clamping surface of the clamping jaw 2, the thrust exerted by the tool 5 on the clamping jaw 2 is removed, and the clamping jaw 2 is reset under the push of the reset unit.

[0023] During the process of opening and closing the jaws 2, the C-shaped groove 21 of the jaws 2 cooperates with the tool clamping block 3 and generates mutual thrust, thereby ensuring that the jaws 2 on both sides can move symmetrically and synchronously, avoiding the stability of clamping and fixing the tool 5 due to differential movement of the jaws 2 on both sides.

[0024] The reset unit continuously generates thrust, so that the clamping jaw 2 rotates around the hinge position, thereby clamping and fixing the tool 5. Compared with clamping by the elasticity of the material of the clamping jaw 2 itself, the reset unit provides thrust, which can effectively ensure the stability of the clamping state, and the clamping jaw 2 will not affect the clamping force due to fatigue during long-term operation. In addition, if the reset unit itself is fatigued and aged, only the reset unit can be replaced, and the maintenance cost is low.

[0025] In some embodiments, the reset unit adopts a compression spring, which is arranged between the clamping jaw block 3 and the tool clamping unit seat 1. The compression spring is used to continuously generate thrust on the clamping jaw block 3, so that the side wall of the C-shaped groove 21 of the clamping jaw 2 is pushed by the clamping jaw block 3, so that the clamping jaw 2 rotates around the hinge position, thereby clamping and fixing the tool 5.

[0026] In some embodiments, the reset unit is a tension spring, which is arranged between the clamping jaws 2 on both sides. The tension spring continuously generates an inward pulling force on the clamping jaws 2, thereby clamping and fixing the tool 5.

[0027] In some embodiments, the reset unit is a torsion spring, which is arranged at the hinged position between the clamping jaw 2 and the tool clamping unit seat 1, with one end of the torsion spring connected to the clamping jaw 2 and the other end connected to the tool clamping unit seat 1. The torsion spring generates a torsional force, thereby driving the clamping jaw 2 to continuously clamp inward, thereby clamping and fixing the tool 5.

[0028] In some embodiments, both sides of the clamping jaw block 3 correspond to the two ends of the C-shaped groove 21 on the clamping jaw 2 and are respectively provided with limiting grooves 31, and the two ends of the C-shaped groove 21 are respectively movably embedded in the corresponding limiting grooves 31. When the clamping jaw block 3 and the clamping jaw 2 move relatively to the limit position, one end of the C-shaped groove 21 will be embedded in the limiting groove 31 of the clamping jaw block 3, so as to prevent the clamping jaw 2 from shaking and affecting the clamping effect of the tool 5, thereby improving the stability of clamping the tool 5.

[0029] In some embodiments, an ejector screw 4 is screwed into the end of the tool clamp unit seat 1 away from the clamping jaw 2, and the end of the ejector screw 4 contacts the end surface of the clamping jaw pressing block 3. By rotating the ejector screw 4, the ejector screw 4 pushes the clamping jaw pressing block 3 to move forward, so that the angle between the clamping jaws 2 on both sides in the clamping state can be adjusted to meet the clamping requirements of tools 5 of different specifications.

[0030] To summarize, the utility model realizes the connection of adjacent tool clamp unit seats by passing the connecting piece through the connecting ear, embeds the teeth of the output gear into the driving hole, connects and surrounds the tool clamp unit seat, and embeds the teeth of the output gear into the driving hole so that the tool clamp unit seat can be used as a chain link, thereby connecting the tool clamp unit seat with the function of the chain, and facilitating the tool clamp unit seat to be directly driven to move by the output gear, thereby reducing the number of components used in the tool magazine as a whole, saving costs, and facilitating the assembly and maintenance of the tool clamp module.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
