The machine tool spindle rotation accuracy is one of the main accuracy indicators of the machine tool, which directly affects the machining accuracy and surface roughness of the machined parts. The machine tool spindle rotation error is a comprehensive error, which is the drift of the actual rotation axis relative to the theoretical rotation axis during the rotation of the spindle.

[0003] However, the existing machine tool spindles have the following defects: the accuracy of the machine tool spindles will decrease due to long-term use. When processing products, the surface roughness and size of the processed products cannot be guaranteed due to the large rotational runout of the machine tool spindle. In addition, due to the large rotational runout of the machine tool spindle, the tool breakage will easily occur. At this time, a solution is needed to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] The present application is further described below with reference to the accompanying drawings:

[0026] like Figures 1 to 4 As shown, the present application provides an adjustable tool handle chuck, including a tool handle body 1, on which a first connecting end 11 and a second connecting end 12 are provided. The first connecting end 11 is suitable for connecting to a machine tool, and the second connecting end 12 is suitable for connecting to a tool head.

[0027] An adjustment ring 2 and an extrusion ring 3 are sequentially sleeved between the first connection end 11 and the second connection end 12. The adjustment ring 2 is rotatably connected to the handle body 1, and the extrusion ring 3 is fixed to the handle body 1. The adjustment ring 2 is provided with a first adjustment member 21 and a second adjustment member 22. The first adjustment member 21 is suitable for moving along a first direction so that the second adjustment member 22 moves or has a tendency to move along a second direction and abuts against the extrusion ring 3.

[0028] In a traditional tool holder chuck, when the machine tool ages and the accuracy decreases, the machining accuracy of the tool head connected to it will be affected through the tool holder. In the present application, the tool holder body 1 can be slightly deformed by adjusting the action of the ring 2 and the extrusion ring 3 in coordination with the compression of the tool holder body 1, so as to change the relative connection positions of the connection between the tool holder body 1 and the machine tool (the first connection end 11) and the connection between the tool holder body 1 and the tool head (the second connection end 12), thereby reducing the vibration of the tool head during rotation and improving the machining accuracy.

[0029] like Figure 3 In the illustrated embodiment, an elastic groove 13 is provided between the first connection end 11 and the second connection end 12 of the handle body 1, the extrusion ring 3 is fixedly connected to the elastic groove 13 on the side close to the second connection end 12, and the adjustment ring 2 abuts against the handle body 1 on the side close to the first connection end 11 of the elastic groove 13. The adjustment ring 2 can maintain the stability of the state of the adjustment ring 2 itself by abutting against the handle body 1, and utilize the cooperation of the first adjustment member 21 and the second adjustment member 22 to actuate the extrusion ring 3 and transmit the force to the first connection end 11 of the handle body 1, so that the relative position of the first connection end 11 and the second connection end 12 is changed, so as to change the jumping condition of the handle body 1 when rotating with the machine tool, and the elastic groove 13 can reduce the difficulty of slight deformation between the first connection end 11 and the second connection end 12 of the handle body 1, so as to assist in increasing the slight deformation amplitude of the handle body 1 caused by the extrusion ring 3.

[0030] In some embodiments, the extrusion ring 3 is threadedly connected to the elastic groove 13 on one side near the second connecting end 12. Since the force transmitted by the extrusion ring 3 at the adjustment ring 2 is transmitted axially along the handle body 1, in order to allow the second connecting end 12 to move in the radial direction of the handle body 1 relative to the first connecting end 11, the extrusion ring 3 needs to apply a force in the radial direction to the handle body 1. The threaded connection between the extrusion ring 3 and the handle body 1 can effectively guide and conduct the radial force of the handle body 1. At the same time, the threaded connection can also reduce the difficulty of processing and assembly, and improve the connection strength.

[0031] like Figures 1 to 3 In the illustrated embodiment, the adjustment ring 2 is provided with a first adjustment channel 23 along the first direction, and a second adjustment channel 24 along the second direction. Both ends of the second adjustment channel 24 are connected to the extrusion ring 3 and the first adjustment channel 23. The first adjustment member 21 is movably arranged in the first adjustment channel 23. The first adjustment member 21 is provided with a connecting groove 211 on a side close to the second adjustment channel 24. The second adjustment member 22 is movably arranged in the second adjustment channel 24. A connecting portion 221 is provided on the side of the first adjustment member 21 away from the extrusion ring 3. The connecting groove 211 and the connecting portion 221 are suitable for being fitted with each other.

[0032] In some embodiments, the first direction is a tangent direction to the circumference of the handle body 1 , which enables the first adjustment channel 23 to have enough space to accommodate the first adjustment member 21 and has a low impact on the structural strength of the adjustment ring 2 .

[0033] In some embodiments, the second direction is the axial direction of the handle body 1 , which enables the second adjustment member 22 to contact the extrusion ring 3 with the shortest movable stroke, thereby reducing the length of the second adjustment channel 24 and reducing the impact on the structural strength of the adjustment ring 2 .

[0034] It can be understood that the first direction and the second direction are designed to be perpendicular to each other, which can improve the matching stability of the first adjusting member 21 and the second adjusting member 22 and effectively reduce the probability that the second adjusting member 22 is pushed back by the extrusion ring 3 to reset the first adjusting member 21.

[0035] In some embodiments, the first adjustment channel 23 and the first adjustment channel 23 are slidably connected, and the first adjustment member 21 can directly slide in the first adjustment channel 23 and change the matching depth of the connecting groove 211 and the connecting portion 221 .

[0036] In some embodiments, inclined surface sections 2111 are provided on both sides of the connecting groove 211. The first adjusting member 21 is suitable for contacting the connecting portion 221 through the inclined surface sections 2111 and pushing the second adjusting member 22. The provision of the inclined surface sections 2111 can improve the sliding speed of the second adjusting member 22 to maintain consistency, thereby facilitating precise adjustment.

[0037] like Figure 3 and 4 In the illustrated embodiment, the first adjusting member 21 and the first adjusting channel 23 are threadedly connected. The first adjusting member 21 can move in the first adjusting channel 23 by rotating using the thread. The first adjusting member 21 has a connecting groove 211 circumferentially in the first direction. During the movement of the first adjusting member 21, the matching depth of the connecting groove 211 and the connecting portion 221 can change to realize the movement of the second adjusting member 22. Compared with the sliding connection between the first adjusting channel 23 and the first adjusting channel 23, the threaded connection does not require an additional limiting mechanism. The movable position of the first adjusting member 21 can be limited by threaded matching, the structure is simpler and more stable, and the installation is more convenient.

[0038] In some embodiments, the first adjusting member 21 is threadedly connected to the first adjusting channel 23 on one side of the connecting groove 211. Since the first adjusting member 21 is disconnected in the middle by the connecting groove 211, it is difficult to process threads on both sides and adapt them. The single-sided setting can reduce the processing difficulty of the first adjusting member 21 and can also reduce the difficulty of matching the first adjusting member 21 with the first adjusting channel 23.

[0039] like Figure 4 In the illustrated embodiment, when the first adjusting member 21 has a connecting groove 211 formed in the circumferential direction of the first direction, the inclined surface section 2111 surrounds the connecting groove 211 in the circumferential direction of the first direction, and the first adjusting member 21 is suitable for contacting the connecting portion 221 through the inclined surface section 2111 and pushing the second adjusting member 22. When the first adjusting member 21 rotates but does not move, the inclined surface section 2111 can be used to keep the position of the second adjusting member 22 unchanged.

[0040] like Figure 4 In the illustrated embodiment, operating holes 212 are provided at both ends of the first adjusting member 21 . The operating holes 212 are preferably hexagonal holes, which can facilitate the rotation of the first adjusting member 21 .

[0041] like Figure 1 and 2 In the illustrated embodiment, a first mark 25 is provided on the extrusion ring 3 , and a second mark 31 is provided on the adjustment ring 2 . The first mark 25 and the second mark 31 are suitable for matching and positioning in the circumferential direction of the handle body 1 .

[0042] In some embodiments, the first mark 25 is a scale line, and the second mark 31 is an indicator symbol. The indicator symbol can cooperate with the scale line to realize the relative position identification of the adjustment ring 2 and the extrusion ring 3 in the circumferential direction.

[0043] like Figure 1In the illustrated embodiment, a locking member 26 is provided on the adjusting ring 2. The locking member 26 is adapted to be close to or away from the shank body 1 at least in the radial direction of the shank body 1. The locking member 26 is used to limit the movement of the adjusting ring 2 to ensure the adjustment accuracy.

[0044] like Figure 3 In the illustrated embodiment, the hilt body 1 is provided with a locking groove 14 along the circumferential direction, and a locking portion 261 is provided at the front end of the locking member 26. When the locking member 26 is close to the hilt body 1, the locking portion 261 and the locking groove 14 are suitable for being fitted with each other. By utilizing the cooperation between the locking groove 14 and the locking portion 261, the stability of the adjusting member in the second direction can be improved, thereby further improving the adjustment accuracy.

[0045] In some embodiments, the cross-section of the locking groove 14 is V-shaped, and the locking portion 261 is conical, which can improve the matching stability between the locking portion 261 and the locking groove 14 and reduce the probability of relative movement between the locking portion 261 and the locking groove 14 in the second direction. Even if movement occurs, it is only a small movement.

[0046] In some embodiments, the taper of the locking portion 261 is not less than the taper of the cross section of the locking groove 14 . Since the locking portion 261 cooperates with the locking groove 14 while rotating, the setting of the taper can reduce the contact wear between the locking portion 261 and the locking groove 14 .

[0047] In some embodiments, a portion of the front end of the locking portion 261 is cut off to reduce the contact wear between the front end of the locking portion 261 and the locking groove 14 .

[0048] like Figure 4 In the illustrated embodiment, there are multiple locking members 26 , which are suitable for being arranged at equal intervals along the circumference of the handle body 1 , so as to improve the locking stability between the adjustment ring 2 and the handle body 1 .

[0049] The operating principle of the present application is as follows: first install the core rod on the tool handle body 1, detect the runout of the tool, loosen the adjustment ring 2 according to the highest position of the runout at the scale mark on the extrusion ring 3, align the indicator symbol (arrow) on the adjustment ring 2 with the scale line at the highest point of the runout on the extrusion ring 3, lock the adjustment ring 2, adjust the first adjustment member 21, let the inclined surface section 2111 of the first adjustment member 21 contact with the connecting portion 221 of the second adjustment member 22, adjust the position of the first adjustment member 21 in the first adjustment channel 23, and push the second adjustment member 22 to move along the second adjustment channel 24 toward the extrusion ring 3 by squeezing the connecting portion 221 of the second adjustment member 22. When the second adjustment member 22 contacts the extrusion ring 3, continue to squeeze the connecting portion 221 of the second adjustment member 22 to push the extrusion ring 3 to cause a slight deformation of the tool handle body 1 to change the highest point of the runout.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
