[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0039] like Figures 1 to 13 As shown, this utility model embodiment provides a transport and fixing device for a machining center. The fixing device is not used while the machining center is working, but only before the machining center needs to be transported, to fix the internal components of the machining center. The machining center includes an electric spindle 01, a moving crossbeam 02, and a fixed crossbeam 03. The moving crossbeam 02 is movably mounted on the fixed crossbeam 03, and the electric spindle 01 is mounted on the moving crossbeam 02. The fixing device includes an electric spindle fixing assembly 10 and a moving crossbeam fixing assembly 20. The electric spindle fixing assembly 10 includes a support portion 11 and a fixing portion 12 connected to each other. The support portion 11 has a support surface 110 and a receiving cavity 111. The support surface 110 is located at the end of the support portion 11 and has an opening 1101 communicating with the receiving cavity 111. The opening 1101 is used for the electric spindle 01 of the machining center to pass through, with a portion of the electric spindle 01 located within the receiving cavity 111, specifically the middle and end portions of the electric spindle 01. The support surface 110 is used to abut against the electric spindle 01 to support the electric spindle 01. The fixing part 12 is connected to the frame of the machining center to fix the position of the support part 11. The moving crossbeam fixing assembly 20 is used to fix the moving crossbeam 02.

[0040] In this embodiment, the support surface 110 abuts against the disk structure on the electric spindle 01. The support surface 110 is located below the disk structure and abuts against and supports the bottom surface of the disk structure. In other embodiments, the support surface 110 may abut against other structures on the electric spindle 01.

[0041] In this embodiment, the machining center is a dual-axis gantry machining center, and two electric spindle fixing components 10 are provided. In other embodiments, it can be other types of machining centers.

[0042] Applying the technical solution of this utility model, the electric spindle fixing assembly 10 supports and abuts the electric spindle 01 through the support surface 110 of the support part 11. The opening 1101 can support and limit the electric spindle 01 in the axial direction, ensuring the stability of the electric spindle 01's position within the machining center and reducing vibration or shaking caused by external impacts during transportation. Furthermore, part of the electric spindle 01 can be located within the receiving cavity 111, which protects the electric spindle 01 and provides circumferential limitation, preventing direct external impacts. It is then fixed to the frame of the machining center by the fixing part 12, ensuring the stability of the electric spindle fixing assembly 10. The moving crossbeam fixing assembly 20 can fix the position of the moving crossbeam 02 on the machining center to prevent displacement and collision with other components due to external impacts during transportation. The above settings can fix the position of the internal components during the transportation of the machining center, preventing the internal components from vibrating, colliding or tilting due to external impacts, which could damage the machining center or reduce its performance, thus improving the stability of the machining center during transportation.

[0043] like Figure 1 As shown, the support part 11 includes a support base 112 and a support frame 113. The support base 112 is connected to the fixing part 12. The support base 112 has a receiving cavity 111. The support frame 113 is disposed on the top of the support base 112. The side of the support frame 113 away from the support base 112 abuts against the electric spindle 01 to form a support surface 110. The electric spindle fixing assembly 10 also includes a first vertical adjustment structure and a first horizontal adjustment structure. The first vertical adjustment structure is disposed between the support base 112 and the support frame 113 to adjust the relative position of the support frame 113 with respect to the support base 112 in the vertical direction. The first horizontal adjustment structure is disposed between the support base 112 and the fixing part 12 to adjust the relative position of the support base 112 with respect to the fixing part 12 in the horizontal direction.

[0044] The first vertical adjustment structure allows adjustment of the relative position of the support frame 113 and the support base 112 in the vertical direction, thereby adjusting the relative position of the support surface 110 and the electric spindle 01 in the vertical direction. The first horizontal adjustment structure allows adjustment of the relative position of the support base 112 and the fixing part 12 in the horizontal direction, thereby adjusting the relative position of the support surface 110 and the electric spindle 01 in the horizontal direction. This ensures that the electric spindle 01 is in the optimal position during fixing, avoiding potential damage caused by insecure fixing or over-tightening, ensuring precise positioning of the electric spindle 01 during transportation, and reducing the impact of vibration on the electric spindle 01 during transportation. Furthermore, the separate design of the support base 112 and the support frame 113, along with the addition of the adjustment structure, allows the electric spindle fixing assembly 10 to adapt to electric spindles 01 of different sizes, improving the versatility and flexibility of the fixing device.

[0045] In this embodiment, the specific structural forms of the first vertical adjustment structure and the first horizontal adjustment structure are not limited, and they can be components such as cylinders, telescopic rods, or lead screws and nuts to complete the adjustment work.

[0046] like Figure 1 As shown, the support frame 113 includes two support plates 1131, which are disposed opposite each other on the top of the support base 112 along a first direction. The first direction forms an angle with the vertical direction. Each support plate 1131 has a first segment and a second segment connected in sequence. The first segment is connected to the support base 112, and the second segment extends from the first segment toward the receiving cavity 111 along the first direction. There is a gap between the ends of the two second segments away from the first segment, forming an opening 1101. Part of the electric spindle 01 is located on the end face of the second segment away from the receiving cavity 111. The end faces of the two second segments away from the receiving cavity 111 cooperate to form a support surface 110. The design of the two support plates 1131 facing each other provides precise positioning and stable support for the electric spindle 01, ensuring its stability during transportation while also reducing material usage and lowering processing costs.

[0047] In this embodiment, the first segment is connected to the outer wall of the support 112; in other embodiments, the first segment is connected to the inner wall of the support 112.

[0048] Wherein, both the first and second directions are horizontal, the X direction is the first direction, and the Y direction is the second direction.

[0049] In a preferred embodiment, the structural outline of the opening 1101 is adapted to the structure of the electric spindle, that is, the end of the second segment away from the first segment is an arc-shaped structure. In this way, when the support plate 1131 supports the electric spindle 01, the distance between the support plate 1131 and the electric spindle is relatively uniform along the circumference of the electric spindle 01, which improves the consistency of the circumferential limit and further enhances the stability of the support part 11.

[0050] In other embodiments, the end of the second segment away from the first segment can be a straight structure, a curved structure, or other structures.

[0051] Specifically, the second segment extends vertically, and a reinforcing rib structure is provided between the first and second segments to improve the stability of the connection between the first and second segments.

[0052] like Figure 1 As shown, the support base 112 is provided with a first mounting hole, and the first section is provided with a first adjustment hole 1132. The first adjustment hole 1132 extends in the vertical direction. The first mounting hole and the first adjustment hole 1132 form a first vertical adjustment structure. The first mounting hole cooperates with the first adjustment hole 1132 through a first fastener to adjust the height of the support plate 1131 relative to the support base 112.

[0053] The design of the first vertical adjustment structure utilizes the cooperation between the first adjustment hole 1132 and the first fastener. By changing the position of the first fastener in the first adjustment hole 1132, the height of the support plate 1131 can be adjusted, so that the support surface 110 can be tightly abutted against the electric spindle 01, ensuring the stable fixation of the electric spindle 01 during transportation and reducing the risk of damage to the electric spindle 01.

[0054] In this application, the number of the first adjustment hole and the first mounting hole is not limited, and can be selected according to the fixing and adjustment requirements.

[0055] like Figure 1 As shown, two mounting bosses 114 are provided opposite to each other on the side wall of the support base 112. The two mounting bosses 114 are provided one-to-one with the two support plates 1131. The first section is connected to the side of the mounting boss 114. The support plate 1131 also has a third section, which is located on the side of the first section away from the second section. The third section is connected to the bottom surface of the mounting boss 114. This can further improve the stability of the connection between the support plate 1131 and the support base 112, and prevent the support plate 1131 from tilting or falling off during support, thereby improving the stability of the support surface 110 supporting the electric spindle 01.

[0056] A second mounting hole is provided on the bottom surface of the mounting boss 114, and a second adjustment hole is provided on the third section. The second adjustment hole extends along the first direction. The second mounting hole cooperates with the second adjustment hole through a second fastener to adjust the position of the support plate 1131 relative to the support base 112 along the first direction, thereby adjusting the size of the opening 1101.

[0057] The second mounting hole, the second adjustment hole, and the second fastener are engaged. By adjusting the position of the second fastener in the second adjustment hole, the relative position between the support plate 1131 and the support base 112 along the first direction can be changed, thereby adjusting the size of the opening 1101 to accommodate electric spindles 01 of different sizes. This further improves the practicality and applicability of the electric spindle fixing assembly 10, while ensuring the precise fixing of the electric spindle 01 during transportation and reducing the risk of vibration or positional displacement of the electric spindle 01 caused by equipment movement.

[0058] In this application, the number of the second adjustment hole and the second mounting hole is not limited, and can be selected according to the fixing and adjustment requirements.

[0059] like Figure 1As shown, the support base 112 includes a base plate 1121 and two connecting brackets 1122. The base plate 1121 is connected to the fixing part 12. The two connecting brackets 1122 are arranged opposite to each other at both ends of the base plate 1121 along a first direction. The two connecting brackets 1122 are arranged one-to-one with two support plates 1131. The support brackets 113 are arranged on the top of the connecting brackets 1122. The fixing part 12 is provided with a third mounting hole, and the base plate 1121 is provided with a third adjustment hole 1123. The third adjustment hole 1123 extends along a second direction, and the second direction forms an angle with the first direction. The third mounting hole and the third adjustment hole 1123 form a first horizontal adjustment structure. The third mounting hole cooperates with the third adjustment hole 1123 through a third fastener to adjust the position of the support base 112 relative to the fixing part 12 in the horizontal direction.

[0060] By adjusting the position of the second fastener in the third adjustment hole 1123, the relative position between the support base 112 and the fixing part 12 in the horizontal direction (second direction) can be changed. In conjunction with the second mounting hole, the second adjustment hole and the second fastener, the relative position of the support surface 110 and the electric spindle 01 in multiple directions on the horizontal plane can be adjusted. This further ensures the precise horizontal fixation of the electric spindle fixing assembly 10 during transportation, thereby further reducing the risk of the electric spindle 01 shifting horizontally due to equipment movement.

[0061] Specifically, two connecting brackets 1122 are arranged opposite each other at both ends of the base plate 1121 along the first direction, and a through-hole is formed between the two connecting brackets 1122 along the second direction. The through-hole is connected to the receiving cavity 111, which facilitates the electric spindle 01 to move into or out of the receiving cavity from the through-hole.

[0062] In this embodiment, the first direction and the second direction are perpendicular to each other.

[0063] In this application, the number of the third adjustment hole and the third mounting hole is not limited, and can be selected according to the fixing and adjustment requirements.

[0064] Two connecting beams are provided on one side of the two connecting frames 1122. The two connecting beams are arranged vertically between the two connecting frames 1122 to enhance the structural strength of the support base 112.

[0065] Specifically, the connecting frame 1122 includes a flat plate, a crossbeam extending in a second direction, and two vertical beams extending in a vertical direction. The two vertical beams are spaced apart on the base plate 1121 in the second direction, and the crossbeam and the mounting boss 114 are spaced apart in the vertical direction between the two vertical beams. The flat plate is fixed above the connecting frame 1122, and its four sides are fixedly connected to the crossbeam, the mounting boss 114, and the two vertical beams, respectively.

[0066] like Figure 1As shown, the fixing part 12 includes a fixing base 121 and a fixing side seat 122. One end of the fixing base 121 is connected to the bottom of the support part 11, and the end of the fixing base 121 away from the support part 11 is connected to the frame of the machining center. One end of the fixing side seat 122 is connected to the side of the support part 11, and the other end of the fixing side seat 122 is connected to the frame of the machining center. The cooperation of the fixing base 121 and the fixing side seat 122 increases the connection area between the fixing part 12 and the machining center. Furthermore, the fixing base 121 and the fixing side seat 122 are positioned on the side walls of the support part 11 at different locations, further enhancing the fixing effect on the support part 11.

[0067] Specifically, the bottom of the fixed base 121 is connected to the bed 05 of the machining center, and the end of the fixed side seat 122 away from the support part 11 is connected to the column 06 of the machining center.

[0068] A second horizontal adjustment structure is provided between the fixed base 121 and the frame to adjust the relative position of the support part 11 with respect to the frame in the horizontal direction. A third horizontal adjustment structure is provided between the fixed side seat 122 and the frame to adjust the relative position of the support part 11 with respect to the frame in the vertical direction. The adjustment directions of the second and third horizontal adjustment structures are at an angle. The provision of the second and third horizontal adjustment structures allows the electric spindle fixing assembly 10 to be finely adjusted according to the size of the machining center frame and the position of the electric spindle 01, improving the adaptability and stability of the fixing device.

[0069] Specifically, the fixed base 121 includes a mounting frame and multiple support legs 1211. A support portion 11 is disposed on the top of the mounting frame, and the multiple support legs are spaced apart at the bottom of the mounting frame. The support legs 1211 are connected to the bed 05. The bed 05 has a fourth mounting hole, and the support legs 1211 have a fourth adjustment hole 1212. The fourth adjustment hole extends horizontally, and the fourth mounting hole and the fourth adjustment hole form a second horizontal adjustment structure. The fourth mounting hole engages with the fourth adjustment hole via a fourth fastener to adjust the relative position of the support portion 11 with the bed 05 in the horizontal direction. The fourth adjustment hole and the fourth mounting hole engage to form the second horizontal adjustment structure.

[0070] In this application, the number of the fourth adjustment hole and the fourth mounting hole is not limited, and can be selected according to the fixing and adjustment requirements.

[0071] The fixed side seat 122 is a tripod, consisting of two triangular steel pieces and a diagonal beam. One triangular steel piece is fixed to the connecting beam on the support base 112, and the other triangular steel piece is connected to the column 06. A sixth mounting hole is provided on the side of the column 06 facing the other triangular steel piece, and a sixth adjustment hole 1221 is provided on the side of the other triangular steel piece facing the column 06. The sixth adjustment hole 1221 extends along a second direction. The sixth mounting hole engages with the sixth adjustment hole via a sixth fastener to adjust the height of the fixed side seat 122 relative to the column 06. The sixth adjustment hole and the sixth mounting hole together form a third horizontal adjustment structure.

[0072] In this application, the number of the sixth adjustment hole 1221 and the sixth mounting hole is not limited, and can be selected according to the fixing and adjustment requirements.

[0073] There are two fixed side seats 122, which are fixed on the two connecting beams respectively.

[0074] Specifically, when using the electric spindle fixing assembly 10, first install the fixing base 121 on the bed 05, then install two connecting brackets 1122 and fixing side seat 122, then drive the electric spindle to move from the port to the receiving cavity 111, and then install two support plates 1131 to support and fix the electric spindle 01.

[0075] like Figures 2 to 4 As shown, the machining center includes two movable crossbeams 02, which are horizontally spaced on a fixed crossbeam 03. The movable crossbeam fixing assembly 20 includes a support rod assembly 21, with both ends of the support rod assembly 21 engaging with the two movable crossbeams 02 to fix their relative positions. The engagement of the support rod assembly 21 with the movable crossbeams 02 restricts their relative movement, preventing collisions during transport and ensuring the fixed position of the movable crossbeams 02, thus reducing the risk of damage due to equipment movement.

[0076] like Figure 5 and Figure 6As shown, the support rod assembly 21 includes a first pipe segment 211, a second pipe segment 212, and an angle fixing structure. The first pipe segment 211 extends at an angle to the extending direction of the movable crossbeam 02. The first pipe segment 211 has a first connecting end and a first adjusting end arranged opposite each other along its extending direction. The first adjusting end is threadedly connected to one of the movable crossbeams 02 to adjust the relative position of the first pipe segment 211 and its corresponding movable crossbeam 02. The second pipe segment 212 extends in the same direction as the first pipe segment 211. The second pipe segment 212 has a second connecting end and a second adjusting end arranged opposite each other along its extending direction. The second adjusting end is threadedly connected to the other movable crossbeam 02 to adjust the relative position of the second pipe segment 212 and its corresponding movable crossbeam 02. The second connecting end corresponds to the first connecting end. The angle fixing structure is disposed between the first connecting end and the second connecting end, and is used to fix the relative rotation angle between the first pipe segment 211 and the second pipe segment 212. The cooperation of the first pipe section 211 and the second pipe section 212 enhances the flexibility of the support rod assembly 21. The threaded connection between the pipe section and the moving crossbeam 02 allows for adjustment of the actual support length of the pipe section, meeting the support requirements of different sizes and specifications. At the same time, the angle fixing structure ensures that after the support length is adjusted, the pipe section is locked not only by the self-locking characteristic of the threaded engagement, but also by the angle fixing structure at the other end of the two pipe sections, further improving the stability of the support.

[0077] Specifically, the first pipe section 211 includes a first square pipe and a first threaded rod 2111 connected in sequence. The first threaded rod 2111 is located at the end of the first square pipe near the moving crossbeam 02, and the angle fixing structure is located at the end of the first square pipe away from the first threaded rod 2111. The first threaded rod 2111 is threadedly connected to the end of the anti-collision seat 07 on one of the moving crossbeams 02.

[0078] The second pipe section 212 includes a second square pipe and a second threaded rod 2121 connected in sequence. The second threaded rod 2121 is located at the end of the second square pipe near the moving crossbeam 02, and the angle fixing structure is located at the end of the second square pipe away from the second threaded rod 2121. The second threaded rod 2121 is threadedly connected to the end of the anti-collision seat 07 on another moving crossbeam 02.

[0079] like Figure 7 and Figure 8As shown, the angle fixing structure includes a first connecting plate 213 and a second connecting plate 214. The first connecting plate 213 is disposed on the first connecting end and has a fifth adjusting hole 2131, which is an annular hole. The second connecting plate 214 is disposed on the second connecting end and has a fifth mounting hole 2141. The fifth mounting hole 2141 engages with the fifth adjusting hole 2131 via a fifth fastener to fix the relative rotation angle between the second pipe segment 212 and the first pipe segment 211.

[0080] When the first pipe segment 211 and the second pipe segment 212 are threadedly connected to their respective anti-collision seats 07, they may be screwed into the anti-collision seats 07 by different lengths, that is, rotated through different rotation angles. By adjusting the position of the fourth fastener in the fifth adjustment hole 2131, the relative rotation angle between the first pipe segment 211 and the second pipe segment 212 can be adapted and fixed, thereby adjusting the relative angular position between the first pipe segment 211 and the second pipe segment 212.

[0081] In this application, the number of the fifth adjustment hole 2131 and the fifth mounting hole 2141 is not limited, and can be selected according to the fixing and adjustment requirements.

[0082] A first reinforcing plate is provided between the first connecting plate 213 and the first pipe section 211. The first reinforcing plate is offset from the fifth adjusting hole 2131 on the first connecting plate 213 to avoid interference. A second reinforcing plate is provided between the second connecting plate 214 and the second pipe section. The second reinforcing plate is offset from the fifth mounting hole 2141 on the second connecting plate 214 to avoid interference.

[0083] like Figure 9 and Figure 10 As shown, the moving crossbeam fixing assembly 20 also includes a fixing frame 22, which is disposed between the moving crossbeam 02 and the fixed crossbeam 03 to fix the relative position between the moving crossbeam 02 and the fixed crossbeam 03. The design of the fixing frame 22, through its connection with the moving crossbeam 02 and the fixed crossbeam 03, achieves the fixation of the moving crossbeam 02, ensuring its stability during transportation and reducing the risk of damage to the moving crossbeam 02 caused by equipment movement.

[0084] Specifically, there are two fixing frames 22, which are used to fix the two moving crossbeams 02 respectively. The fixing frame 22 is a triangular structure frame. The bottom of the fixing frame 22 is connected to the fixed crossbeam 03 by fasteners. The side wall of the fixing frame 22 is connected to the moving crossbeam 02 by fasteners. The bottom of the fixing frame 22 and the side wall of the fixing frame 22 are provided with waist-shaped holes, which are fixedly connected to the fixed crossbeam 03 and the moving crossbeam 02 by fasteners respectively, so as to adjust the fixed position of the moving crossbeam 02.

[0085] like Figures 11 to 13As shown, the machining center also includes a slide saddle assembly 04, which is movably mounted on the moving crossbeam 02. The electric spindle 01 is mounted on the slide saddle assembly 04. The fixing device also includes a slide saddle fixing member 30, which is disposed between two adjacent side walls of the slide saddle assembly 04 and the moving crossbeam 02 to fix the relative position between the slide saddle assembly 04 and the moving crossbeam 02. In this application, the specific location of the slide saddle fixing member 30 is not limited.

[0086] Specifically, there are two sliding saddle fixing parts 30, which are respectively set on both sides of the sliding saddle assembly 04 along the extension direction of the moving crossbeam 02. The sliding saddle fixing parts 30 are triangular structure frames. One side of the two adjacent side walls of the sliding saddle fixing parts 30 is connected to the moving crossbeam 02 by fasteners, and the other side of the sliding saddle fixing parts 30 is connected to the sliding saddle assembly 04 by fasteners. Both adjacent side walls of the sliding saddle fixing parts 30 are provided with waist-shaped holes, which are fixedly connected to the moving crossbeam 02 and the sliding saddle assembly 04 by fasteners, respectively, so as to adjust the fixed position of the sliding saddle assembly 04.
