Technical Field

[0001] This utility model relates to the field of tool holder nut clamping technology, and in particular to an automatic clamping transmission device suitable for CNC spring collet tool holders. Background Technology

[0002] CNC collet tool holders are widely used tools in CNC machining centers. Currently, they are typically manually loaded and unloaded using a special wrench. The tool loading process is as follows: First, place the tool of different models into the tool holder locking seat. Then, select the matching special wrench and rotate it clockwise to rotate the tool holder nut, thus locking the tool. Similarly, rotate the wrench counterclockwise to release the tool.

[0003] Currently, the clamping and disassembly of cutting tools are mostly done manually with special wrenches, which cannot achieve automation of tool clamping and disassembly, resulting in low efficiency. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an automatic clamping transmission device suitable for CNC collet tool holders, which is connected to an automated drive mechanism to realize automatic tool loading and unloading.

[0005] This utility model provides an automatic clamping transmission device suitable for CNC collet tool holders, comprising:

[0006] The card holder has a through hole in the center and at least one through groove on its top surface. The two sides of the through groove are symmetrically provided with grooves communicating with it.

[0007] The positioning component includes a slider that is slidably disposed in the through groove. A positioning block is fixedly disposed at one end of the slider near the through hole, and a first guide block is disposed at the other end. The positioning block cooperates with a keyway opened on the tool holder nut.

[0008] An elastic element is disposed in the groove and fixedly connected to the slider. The elastic force of the elastic element can push the slider to move away from the through hole, so that the positioning block is housed in the through groove.

[0009] The driving component is slidably sleeved on the outer wall of the card holder. The driving component can slide along the axial direction of the card holder to push the first guide block to move in the direction close to the through hole and compress the elastic element, so that the positioning block extends into the through hole.

[0010] Furthermore, the driving component includes a sliding sleeve slidably sleeved on the outer wall of the card holder, and a second guide block that matches the first guide block is provided on the sliding sleeve. The sliding sleeve can drive the second guide block to slide along the axial direction of the card holder, so that the first guide block moves in a direction close to the through hole.

[0011] Furthermore, the first guide block has a first inclined surface on the side away from the slider, and the second guide block has a second inclined surface on the side away from the sliding sleeve. The second inclined surface and the first inclined surface are arranged opposite to each other and have the same inclination angle.

[0012] Furthermore, the sliding sleeve has a through hole, a locking rod is inserted into the through hole, and the card head seat has a locking hole that matches the locking rod. When the positioning block extends into the through hole, the locking rod is inserted into the locking hole and fixed.

[0013] Furthermore, the elastic element includes a guide rod and a spring. The guide rod is fixedly disposed in the groove, the slider is slidably connected to the guide rod, the spring is sleeved on the outside of the guide rod, one end of the spring is fixedly connected to the end of the groove near the through hole, and the other end is fixedly connected to the slider.

[0014] Furthermore, the top of the card holder has two through slots symmetrically formed.

[0015] Furthermore, a limiting plate is symmetrically provided on the top of the card holder above the through hole.

[0016] Furthermore, the top of the card holder is symmetrically provided with fixing parts for connecting with the automatic rotation mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model features a collet holder fixedly connected to an automatic rotation mechanism, replacing the need for a manual wrench and enabling automated tool assembly and disassembly. When clamping the tool, the tool is first installed in the tool holder locking seat. Then, the automatic clamping transmission device of the CNC spring collet tool holder is fitted onto the outer wall of the tool holder nut. The automatic clamping transmission device moves downwards to the keyway position and stops. Then, the sliding member slides upwards, and the second guide block on the sliding member pushes the first guide block to move along the direction close to the through hole. The movement of the first guide block drives the slider to move, thereby compressing the elastic member. The compressed elastic member causes the positioning block to extend outside the through groove and insert into the keyway of the tool holder nut. The sliding member is then locked, ensuring the positioning block is stably inserted and fixed in the keyway, thus completing the fixing of the tool holder nut. The automatic rotation mechanism drives the automatic clamping transmission device of the CNC spring collet tool holder to rotate, clamping the tool.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1-4This utility model provides an automatic clamping transmission device suitable for CNC collet tool holders, comprising:

[0033] The chuck seat 1 has a through hole 11 in the center and at least one through groove 12 on its top surface. The through groove 12 has symmetrical grooves 13 communicating with it on both sides. Specifically, the diameter of the through hole 11 is slightly larger than the outer wall diameter of the tool holder nut 5, so that the chuck seat 1 can be fitted onto the outer wall of the tool holder nut 5.

[0034] The positioning component 2 includes a slider 21 that is slidably disposed in the through groove 12. A positioning block 22 is fixedly disposed at one end of the slider 21 near the through hole, and a first guide block 23 is disposed at the other end. The positioning block 22 cooperates with the keyway 51 opened on the tool holder nut 5. Specifically, a sliding groove is provided at the bottom of the through groove 12, and the slider 21 is slidably connected to the sliding groove.

[0035] The elastic element 3 is disposed in the groove 13 and is fixedly connected to the slider 21. The elastic force of the elastic element 3 can push the slider 21 to move away from the through hole 11 so that the positioning block 22 can be stored in the through groove 12.

[0036] The driving component 4 is slidably sleeved on the outer wall of the card holder 1. The driving component 4 can slide along the axial direction of the card holder 1 to push the first guide block 23 to move in the direction close to the through hole 11 and compress the elastic component 3, so that the positioning block 22 extends into the through hole 11.

[0037] In this embodiment, when clamping the tool, the tool is first installed in the tool holder locking seat, and the chuck seat 1 is installed on the automatic rotation mechanism. Then, the through hole of the chuck seat 1 is inserted into the outer wall of the tool holder nut 5 from top to bottom. When the positioning block 22 is aligned with the keyway 51 on the tool holder nut 5, the upward sliding drive member 4 is slid upward. During the upward movement, the drive member 4 pushes the first guide block 23 close to the through hole 11, thereby driving the slider 21 to squeeze the elastic member 3. The elastic member 3 deforms, and the positioning block 22 extends into the through hole 11 and is inserted into the keyway 51 for fixation, thus completing the clamping of the tool holder nut. The automatic rotation mechanism drives the automatic clamping transmission device of the CNC spring collet tool holder to rotate clockwise, and the tool nut 5 rotates synchronously, and the tool is clamped. When rotating counterclockwise, the tool is released.

[0038] The automatic clamping transmission device of the CNC spring collet tool holder in this application is connected to the automatic rotation mechanism to realize the automation of tool clamping and unclamping, thereby improving the efficiency of tool clamping and unclamping. In addition, this application adopts a positioning component 2, an elastic component 3 and a driving component 4, which has a simple structure and makes it easy to clamp the nut of the spring collet tool holder.

[0039] Specifically, when the elastic element 3 is not subjected to external force, the positioning block 22 is completely housed in the through groove 12, preventing the positioning block 22 from extending into the through hole 11 and affecting the insertion of the chuck seat 1 onto the tool holder nut 5.

[0040] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the driving component 4 includes a sliding sleeve 41 that is slidably sleeved on the outer wall of the card holder 1. The sliding sleeve 41 is provided with a second guide block 42 that matches the first guide block 23. The sliding sleeve 41 can drive the second guide block 42 to slide along the axial direction of the card holder 1, so that the first guide block 23 moves in the direction close to the through hole 11.

[0041] In this embodiment, a groove is provided on the outer wall of the card holder 1 in the vertical direction. The sliding sleeve 41 is slidably connected to the groove to achieve sliding. Pushing the sliding sleeve 41 upward can drive the second guide block 42 to contact the first guide block 23. During the upward movement, the second guide block 42 pushes the first guide block 23 to move in the direction close to the through hole 11, thereby driving the slider 21 and the positioning block 22 to move in the direction close to the through hole 11. The positioning block 22 extends into the through hole 11 to fix the tool holder nut 5 sleeved in the through hole 11.

[0042] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the first guide block 23 has a first inclined surface on the side away from the slider 21, and the second guide block 42 has a second inclined surface on the side away from the sliding sleeve 41. The second inclined surface and the first inclined surface are opposite to each other and have the same inclination angle.

[0043] Specifically, the second guide block 42 is located below the first guide block 23. As the second guide block 42 moves upward, the second inclined surface pushes the first guide block 23 to move in the direction close to the through hole 11. The structure is simple and convenient to push the positioning block 22 so that it can be inserted into the keyway 51 on the tool holder nut 5 and fixed.

[0044] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, the sliding sleeve 41 has a through hole, and a locking rod 43 is inserted into the through hole. The card holder 1 has a locking hole 14 that matches the locking rod 43. When the positioning block 22 extends into the through hole 11, the locking rod 43 is inserted into the locking hole 14 and fixed.

[0045] In this embodiment, the locking rod 43 is a threaded rod, and the locking hole 14 is a threaded hole. When the positioning block 22 is inserted into the keyway 51 of the tool holder nut 5 and fixed, the locking rod 43 is inserted into the locking hole 14 and fixed by the thread.

[0046] In a preferred embodiment, such as Figure 1 andFigure 2 As shown, the elastic element 3 includes a guide rod and a spring. The guide rod is fixedly installed in the groove 13. The slider 21 is slidably connected to the guide rod. The spring is sleeved on the outside of the guide rod. One end of the spring is fixedly connected to the end of the groove 13 near the through hole 11, and the other end is fixedly connected to the slider 21.

[0047] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, two through slots 12 are symmetrically formed on the top of the chuck holder 1. Specifically, the arrangement of the two through slots 12 ensures that the automatic clamping transmission device of the CNC spring collet tool holder of this application is subjected to balanced forces during rotation, thereby improving operational reliability and stability.

[0048] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, a limiting plate 15 is symmetrically arranged on the top of the chuck 1 above the through hole 11. Specifically, during the process of the chuck 1 being inserted into the tool holder nut 5 from top to bottom, when the limiting plate 15 abuts against the top of the tool holder nut 5, the positioning block 22 aligns with the keyway 51, which facilitates the quick determination of the installation position of the automatic clamping transmission device of the CNC spring collet tool holder.

[0049] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the top of the chuck holder 1 is also symmetrically provided with fixing members 16 for connecting with the automatic rotary mechanism. Specifically, the fixing members 16 can be bolts, which facilitate the fixing of the automatic clamping transmission device of the CNC spring collet tool holder of this application to the automatic rotary mechanism.
