[0066] In some embodiments of the present application, the multi-spindle machining tool 100 includes an electric spindle mounting device 120 , which is integrally connected to the machine head connecting device 110 , and the electric spindle mounting device 120 is provided with multiple electric spindle mounting portions 121 .

[0067] In some embodiments of the present application, the multi-spindle machining tool 100 includes a plurality of electric spindles 130 , and each electric spindle 130 is mounted on a different electric spindle mounting portion 121 .

[0068] In some embodiments of the present application, the multi-spindle machining tool 100 has multiple electric spindles 130 installed on its electric spindle mounting device 120, and is connected to the head 200 of the CNC machining equipment 1 by setting a head connecting device 110, so that the multi-spindle machining tool 100 can be installed as a whole on the head 200 of the CNC machining equipment 1, so that the CNC machining equipment 1 can drive the multiple electric spindles 130 to work synchronously, thereby enabling multiple workpieces to be processed simultaneously, or a single workpiece to perform multi-track processing simultaneously, which significantly improves the CNC machining efficiency.

[0069] In some embodiments of the present application, the multi-spindle machining tool 100 and the electric spindle 130 have the advantages of high speed, high precision and low noise. Correspondingly, the CNC machining equipment 1 equipped with the multi-spindle machining tool 100 also has corresponding advantages.

[0070] In some embodiments of the present application, the plurality of electric spindles 130 are arranged parallel to each other along a first direction, the first direction is perpendicular to the axial direction of the electric spindle 130 , and the axial direction of the electric spindle 130 is parallel to the axial direction of the head 200 of the CNC machining equipment 1 .

[0071] like Figures 1 to 4 As shown, in some embodiments of the present application, a plurality of electric spindles 130 are arranged along a first direction (eg Figure 1 The first direction is perpendicular to the axis direction of the electric spindle 130 , and the axis direction of the electric spindle 130 is parallel to the axis direction of the machine head 200 of the CNC machining equipment 1 .

[0072] Multiple electric spindles 130 are constructed to be arranged parallel to each other along a first direction perpendicular to the axial direction of the electric spindle 130, and the axis of the electric spindle 130 is parallel to the axis of the head 200 of the CNC machining equipment 1, so that the motion trajectory of the electric spindle 130 is consistent with the motion trajectory of the head 200 of the CNC machining equipment 1, which facilitates the design and control of the machining trajectory.

[0073] In some embodiments of the present application, the machine head 200 of the CNC machining equipment 1 is positioned vertically downward. The multi-spindle machining fixture 100 is located at the bottom of the CNC machining equipment 1, and the electric spindle mounting device 120 is located to the side of the machine head connecting device 110 to avoid the installation of the electric spindle 130. The multiple electric spindles 130 are arranged horizontally and parallel to each other, with the machining ends of the electric spindles 130 facing vertically downward.

[0074] Figure 5 This is a perspective view of a multi-spindle machining tool according to an embodiment with the fixed installation portion of the electric spindle installation device omitted; Figure 6 is a perspective view of a fine-tuning assembly of a multi-spindle machining tool according to an embodiment; Figure 7 It is a three-dimensional diagram of the assembly structure of the electric spindle and the electric spindle mounting device of the multi-spindle machining tool according to the embodiment.

[0075] Reference Figures 5 to 7 , while combining Figures 1 to 4 In some embodiments of the present application, the electric spindle mounting device 120 includes a fixed mounting portion 122, an adjustable mounting portion 123 and an adjustment assembly.

[0076] The fixed mounting portion 122 is the fixed portion of the electric spindle mounting device 120, which is fixedly connected to the machine head connecting device 110. After being installed in place, the fixed mounting portion 122 is fixed. The fixed mounting portion 122 is provided with an electric spindle mounting portion 121 for mounting the electric spindle 130.

[0077] The adjustable mounting portion 123 and the fixed mounting portion 122 are arranged along the first direction. The adjustable mounting portion 123 is also provided with an electric spindle mounting portion 121 for mounting an electric spindle 130. Multiple electric spindles 130 are distributed and mounted on the fixed mounting portion 122 and the adjustable mounting portion 123.

[0078] To facilitate installation of the electric spindle 130, both the fixed mounting portion 122 and the adjustable mounting portion 123 are constructed as two halves, each of which is connected in pairs. The electric spindle mounting portion 121 is a through-hole that mates with the circumferential outer wall of the electric spindle 130. Accordingly, the electric spindle mounting portion 121 also has a two-part, matching structure. The two halves of the fixed mounting portion 122 are joined and fastened together using screws d. The two halves of the adjustable mounting portion 123 are also joined and fastened together using screws d, clamping the electric spindle 130 within the electric spindle mounting portion 121.

[0079] The adjustment component connects the adjustable mounting part 123 and the fixed mounting part 122, and the adjustment component is configured as follows: by operating the adjustment component, the position of the adjustable mounting part 123 relative to the fixed mounting part 122 can be adjusted in a first direction, that is, the arrangement direction of the electric spindle 130, thereby adjusting the spacing between adjacent electric spindles 130, thereby improving processing flexibility and tooling versatility.

[0080] In some embodiments of the present application, the adjustment assembly includes a coarse adjustment assembly to achieve coarse adjustment of the distance between adjacent electric spindles 130 .

[0081] like Figure 3 and Figure 5 As shown, the coarse adjustment assembly includes a coarse adjustment component 124 , a first locking component 125 and a second locking component 126 .

[0082] The coarse adjustment component 124 is formed with an adjustment slot 127 extending along the first direction. The adjustment slot 127 is a through hole.

[0083] The first locking member 125 passes through the adjusting slot 127 and locks the coarse adjustment member 124 to the fixed mounting portion 122 .

[0084] The second locking member 126 passes through the adjustment slot 127 and locks the coarse adjustment member 124 to the adjustable mounting portion 123 .

[0085] The first locking part can always be in a locked state to connect the coarse adjustment part 124 to the fixed mounting part 122. When it is necessary to adjust the distance between the electric spindle 130 on the adjustable mounting part 123 and the electric spindle 130 on the fixed mounting part 122, the second locking part 126 is operated to put it in a non-locking state, and then the adjustable mounting part 123 is moved closer to or away from the fixed mounting part 122 along the first direction. When the adjustable mounting part 123 reaches the appropriate position, the second locking part 126 locks the adjustable mounting part 123 to be connected to the fixed mounting part 122. At this time, the position of the second locking part 126 in the adjustment long hole 127 changes.

[0086] The coarse adjustment component has a fast adjustment speed and a wide adjustment range, and can realize rapid adjustment of the electric spindle 130 under working conditions where the adjustment accuracy requirement is not high.

[0087] In some embodiments of the present application, the coarse adjustment component 124 is a block-shaped structure, the adjustment long hole 127 is a runway-shaped through hole, the first locking component 125 and the second locking component 126 are both locking screws, and accordingly, the adjustable mounting part 123 is provided with a plurality of locking screw holes arranged at intervals along the first direction, so as to cooperate with the second locking component 126 to achieve locking when reaching the corresponding adjustment position.

[0088] Since the coarse adjustment component not only realizes the spacing adjustment of the electric spindle 130, but also serves to connect the adjustable mounting part 123 and the fixed mounting part 122, in order to improve the connection reliability of the adjustable mounting part 123 and the fixed mounting part 122, the coarse adjustment components are set in multiple places, such as arranging multiple circumferentially at the connection between the adjustable mounting part 123 and the fixed mounting part 122 to ensure that the adjustable mounting part 123 and the fixed mounting part 122 are reliably connected.

[0089] In some embodiments of the present application, the adjustment component includes a fine-tuning component to achieve fine-tuning of the distance between adjacent electric spindles 130 and improve the adjustment accuracy.

[0090] like Figures 3 to 7 As shown, the fine-tuning assembly includes a fine-tuning stud 128 , wherein a rotation driving portion 1281 is provided at one end of the fine-tuning stud 128 and an external thread 1282 is provided at the other end.

[0091] The fine-tuning stud 128 extends along the first direction and passes through the adjustable mounting portion 123. It is configured to only rotate relative to the adjustable mounting portion 123 but not to perform telescopic movement. The end where its external thread 1282 is located extends out of the adjustable mounting portion 123, and the end where the rotation drive portion 1281 is located also extends out of the adjustable mounting portion 123 for easy operation.

[0092] An internal threaded hole is correspondingly provided on the fixed installation portion 122 , and the external thread 1282 of the fine-tuning stud 128 cooperates with the internal threaded hole on the fixed installation portion 122 .

[0093] By operating the rotation driving portion 1281 to rotate the fine-tuning screw 128, the adjustable mounting portion 123 is driven to move closer to or away from the fixed mounting portion 122 along the first direction, thereby achieving position adjustment.

[0094] If the adjustment assembly includes both the coarse adjustment assembly and the fine adjustment assembly, when operating the fine adjustment assembly for adjustment, the second locking component 126 of the coarse adjustment assembly needs to be operated to the unlocked state.

[0095] The fine-tuning component has high adjustment accuracy, and can realize position adjustment of the electric spindle 130 under working conditions that require high adjustment accuracy.

[0096] In order to ensure that the fine-tuning stud 128 can only rotate relative to the adjustable mounting part 123 but not move telescopically, a flange 1283 can be provided on the outer peripheral surface of the fine-tuning stud 128. Accordingly, the channel on the adjustable mounting part 123 for the fine-tuning stud 128 to pass through has a groove for accommodating the flange 1283. The flange 1283 cooperates with the groove to limit the telescopic movement of the fine-tuning stud 128 relative to the adjustable mounting part 123.

[0097] The fine-tuning assembly further includes a driving gear 129 , which is rotatably mounted on the adjustable mounting portion 123 ; accordingly, the rotation driving portion 1281 has external teeth, and the driving gear 129 is meshed with the rotation driving portion 1281 .

[0098] The rotation driving part 1281 can be a gear structure formed on one end of the fine-tuning stud 128, which is coaxial with the fine-tuning stud 128 and meshes with the driving gear 129. By rotating the driving gear 129, the fine-tuning stud 128 is driven to rotate through the rotation driving part 1281.

[0099] The above-mentioned fine-tuning component has a simple structure, low cost, and is easy to operate.

[0100] At the same time, in order to make the adjustable mounting portion 123 move smoothly relative to the fixed mounting portion 122 during fine adjustment, two fine adjustment studs 128 are provided in parallel. Figure 6 As shown, the two fine-tuning studs 128 have exactly the same structure, and the driving gear 129 is arranged between the two fine-tuning studs 128. The driving gear 129 is directly engaged with the rotating driving part 1281 of the first fine-tuning stud 128. The driving gear 129 and the rotating driving part 1281 of the second fine-tuning stud 128 are provided with a transmission gear 1210. The transmission gear 1210 is rotatably set on the adjustable mounting part 123. The driving gear 129 is indirectly engaged with the rotating driving part 1281 of the second fine-tuning stud 128 through the transmission gear 1210. This can ensure that when the driving gear 129 is rotated, the two fine-tuning studs 128 can rotate synchronously and in the same direction of rotation, thereby driving the same adjustable mounting part 123 close to or away from the fixed mounting part 122.

[0101] like Figures 1 to 5 as well as Figure 7 As shown, an adjustable mounting portion 123 is respectively provided on two opposite sides of the fixed mounting portion 122 , and each adjustable mounting portion 123 is connected to the fixed mounting portion 122 via the aforementioned adjustment assembly.

[0102] An adjustable mounting portion 123 is provided on two opposite sides of the fixed mounting portion 122 , respectively, so that the number of installed electric spindles 130 can be increased accordingly, thereby further improving the CNC machining efficiency.

[0103] The fixed connection between the fixed installation portion 122 of the electric spindle installation device 120 and the machine head connection device 110 can be achieved by using a plurality of screws b.

[0104] Figure 8 It is a three-dimensional view of the head connection device of the multi-spindle machining tool according to the embodiment.

[0105] To improve the convenience of connection and improve the efficiency of connection, such as Figure 4 、 Figure 7 and Figure 8 As shown, the fixed installation portion 122 and the head connecting device 110 are provided with sliding guide structures that cooperate with each other.

[0106] By arranging mutually cooperating sliding guide structures on the fixed mounting part 122 and the machine head connecting device 110, when the fixed mounting part 122 is installed on the machine head connecting device 110, the fixed mounting part 122 can be slid to a suitable mounting position and then fixed, so that the position of the fixed mounting part 122 can be adjusted.
