[0001] This utility model relates to the field of CNC machine tool production and assembly technology, and in particular to a tooling mechanism, assembly device and CNC machine tool for spindle box assembly. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools effectively solve the problems of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] In the traditional CNC machine tool production and assembly process, the spindle box is installed sequentially on the machine tool body. This assembly process is inconvenient in actual operation, has low production efficiency, and prolongs the overall machine manufacturing cycle. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling mechanism, assembly device and CNC machine tool for assembling spindle boxes, so as to solve the problem of difficult spindle box installation during machine tool assembly in the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model provides a tooling mechanism for assembling a spindle box, including a support bracket and a rotary drive assembly disposed on the support bracket. The rotary drive assembly includes at least a drive assembly, a transmission assembly, and a rotary bracket assembly connected in sequence. The drive assembly is used to drive the transmission assembly to rotate so as to drive the rotary bracket assembly to rotate.

[0007] The rotating support assembly includes a rotating support and a plurality of mounting pads disposed on the rotating support. The rotating support is connected to the transmission assembly. The spindle box can be detachably connected to the rotating support through the mounting pads. When the drive assembly drives the transmission assembly to rotate so as to drive the rotating support assembly to rotate, the spindle box rotates synchronously.

[0008] As a further improvement of one embodiment of the present invention, the rotating bracket includes a first rotating bracket and a second rotating bracket connected to each other. The first rotating bracket is connected to the transmission assembly through a plurality of fasteners, and the second rotating bracket is connected to the side of the first rotating bracket opposite to the transmission assembly.

[0009] The second rotating bracket has multiple mounting positions on the side opposite to the first rotating bracket, and the mounting positions are used to mount the mounting pad.

[0010] As a further improvement of one embodiment of the present invention, the rotating bracket is generally rectangular in shape, and the number of mounting positions and mounting pads is set to four, with the four mounting positions located at the four corners of the second rotating bracket.

[0011] As a further improvement of one embodiment of the present invention, the drive assembly includes a motor and a reducer connected to each other, and the reducer is connected to the transmission assembly.

[0012] As a further improvement of one embodiment of the present invention, the tooling mechanism further includes a control component, which is mounted on the support bracket and electrically connected to the motor for controlling the start and stop of the motor.

[0013] The control component includes a first button and a second button. When the control component receives a control signal from the first button, the control component controls the motor to rotate forward; when the control component receives a control signal from the second button, the control component controls the motor to rotate in reverse.

[0014] As a further improvement of one embodiment of the present utility model, the transmission assembly includes a housing and a transmission shaft disposed within the housing. The housing is mounted and connected to the support bracket. One end of the transmission shaft is connected to the drive assembly, and the other end of the transmission shaft is connected to the rotating bracket.

[0015] The drive assembly is used to drive the transmission shaft to rotate, thereby causing the rotating bracket to rotate.

[0016] As a further improvement of one embodiment of the present utility model, the support bracket includes a bottom bracket and a mounting bracket. The area directly above the bottom bracket is divided into a first region and a second region. The mounting bracket is fixed to the first region, and a triangular roof structure is formed between the mounting bracket and the bottom bracket located in the first region. The rotation drive assembly is connected to the crossbeam of the triangular roof structure.

[0017] The second region is located on the side of the first region opposite to the side where the spindle box is installed.

[0018] As a further improvement of one embodiment of the present invention, the tooling mechanism further includes a counterweight block, which is disposed on the bottom support located in the second region.

[0021] Compared with the prior art, the beneficial effects of this utility model include at least the following: This utility model provides a tooling mechanism for assembling a spindle box. The spindle box is detachably mounted on a rotating bracket of this tooling mechanism. A drive component drives a transmission component to rotate, thereby rotating the rotating bracket and causing the spindle box to rotate synchronously. This allows the spindle box to be rotated to the required installation position angle, making it easier for operators to assemble the spindle box onto the machine tool. In addition, multiple detachable mounting pads are provided on the rotating bracket. The spindle box is detached and mounted on the rotating bracket via these mounting pads. Operators can adapt the spindle box of different machine tools by replacing different mounting pads. Furthermore, when the threaded holes fastening the spindle box become worn due to repeated detachment and reassembly of the spindle box over a long period, simply replacing the mounting pads ensures the stability of the installation between the spindle box and the rotating bracket, greatly saving production costs.

Detailed Implementation

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0035] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0036] See also Figures 1-4 and Figures 10-11 This utility model provides a tooling mechanism for assembling a spindle box, including a support bracket 100 and a rotary drive assembly 200 disposed on the support bracket 100. The rotary drive assembly 200 includes at least a drive assembly 210, a transmission assembly 220 and a rotary bracket assembly 230 connected in sequence. The drive assembly 210 is used to drive the transmission assembly 220 to rotate so as to drive the rotary bracket assembly 230 to rotate.

[0037] The rotating support assembly 230 includes a rotating support 231 and multiple mounting pads 232 disposed on the rotating support 231. The rotating support 231 is connected to the transmission assembly 220. The spindle box 500 can be detachably connected to the rotating support 231 via the mounting pads 232. When the drive assembly 210 drives the transmission assembly 220 to rotate, thereby rotating the rotating support assembly 230, the spindle box 500 rotates synchronously. Thus, before assembling the spindle box 500 with the machine tool, it is first mounted on the rotating support 231 of the tooling mechanism in this embodiment. The spindle box 500 can be assembled simultaneously with the machine tool assembly. After the machine tool assembly is completed, the drive assembly 210 can drive the transmission assembly 220 to rotate, thereby rotating the rotating support 231 and causing the spindle box 500 to rotate synchronously. This allows the spindle box 500 to be rotated to the required installation position angle, enabling direct assembly of the pre-positioned spindle box 500 onto the machine tool, significantly shortening the assembly cycle. In addition, multiple removable mounting pads 232 are provided on the rotary support 231. The spindle box 500 is disassembled and installed on the rotary support 231 through these mounting pads 232. Operators can adapt the spindle box 500 of different machine tools by replacing different mounting pads 232. When the spindle box 500 is disassembled and installed with the rotary support 231 for a long time and repeatedly, causing wear on the threaded holes that fasten the spindle box 500, it is only necessary to simply replace the mounting pads 232 to ensure the stability of the installation between the spindle box 500 and the rotary support 231, which greatly saves production costs.

[0038] See Figure 5 The rotating bracket 231 includes a first rotating bracket 2311 and a second rotating bracket 2312 connected to each other. The first rotating bracket 2311 is connected to the transmission assembly 220, and the second rotating bracket 2312 is connected to the side of the first rotating bracket 2311 opposite to the transmission assembly 220. The side of the second rotating bracket 2312 opposite to the first rotating bracket 2311 has multiple mounting positions 233 for mounting mounting pads 232. Specifically, multiple mounting pads 232 are mounted on the second rotating bracket 2312, specifically on the side of the second rotating bracket 2312 opposite to the first rotating bracket 2311. The spindle box 500 is connected to the second rotating bracket 2312 through these mounting pads 232.

[0039] Combination Figures 6-8 The first rotating bracket 2311 and the transmission assembly 220 are connected by a plurality of fasteners 234. Specifically, the first rotating bracket 2311 and the transmission assembly 220 are connected and locked by eight fasteners 234.

[0040] Preferably, fastener 234 is an M12-35 socket head cap screw.

[0041] Of course, this utility model does not limit the number and type of fasteners 234, and can be adjusted according to the actual situation to ensure that the first rotating bracket 2311 and the transmission component 220 can be locked together, and that the transmission component 220 can smoothly drive the first rotating bracket 2311 to rotate synchronously when it rotates.

[0042] Combination Figure 1 and Figure 5 The rotating bracket 231 has an overall rectangular structure, the first rotating bracket 2311 has an H-shaped structure, and the outer frame of the second rotating bracket 2312 has a rectangular structure. There are four mounting positions 233 and four mounting pads 232. The four mounting positions 233 are located at the four corners of the second rotating bracket 2312 on the side opposite to the first rotating bracket 2311, and the four mounting pads 232 are respectively connected to the mounting positions 233, and the mounting pads 232 are detachably connected to the mounting positions 233.

[0043] Specifically, the mounting pad 232 can be adapted to different models of machine tool spindle boxes 500. That is, by selecting different mounting pads 232, the spindle boxes 500 of different machine tool models can be installed and connected to the second rotary support 2312. In other words, the tooling mechanism provided by this utility model can be used to install spindle boxes 500 of different machine tool models, only requiring the replacement of the corresponding mounting pad 232.

[0044] More specifically, the spindle box 500 has pre-machined through holes that correspond to the threaded holes on the mounting pad 232. Multiple screws are used to connect and secure the spindle box 500 and the mounting pad 232 during installation. For example, when installing the spindle box 500 and the mounting pad 232, 16 M10-70 screws are passed through the through holes on the spindle box 500 and screwed into the threaded holes on the mounting pad 232. Then, a torque wrench is used to tighten the screws, with a preload of approximately 60 N·m.

[0045] Of course, when the same model of spindle box 500 is disassembled and installed with the second rotating bracket 2312 for a long time and many times, since the threaded hole is opened on the mounting pad 232, when the threaded hole is worn due to repeated disassembly and assembly of spindle box 500, it is only necessary to simply replace the mounting pad 232 of the same model to ensure the installation stability of spindle box 500 and rotating bracket 231, which greatly saves production costs.

[0046] The mounting pad 232 can be fixedly installed in the mounting position 233 of the second rotary bracket 2312 using screws or other fasteners. Since the mounting pad 232 only needs to be replaced after multiple disassemblies and reassemblies of the spindle box 500, the threaded hole used for the fixed connection between the mounting pad 232 and the second rotary bracket 2312 will only experience a limited number of wear cycles, ensuring a secure connection between the mounting pad 232 and the second rotary bracket 2312. The threaded hole structure used for the mating of the mounting pad 232 and the second rotary bracket 2312 can be provided on the mounting pad 232 or on the mounting position 233 of the second rotary bracket 2312.

[0047] See Figure 1 , Figure 3 and Figure 4 The drive assembly 210 includes a motor 211 and a reducer 212 connected to each other. The reducer 212 is connected to the transmission assembly 220. The motor 211 drives the reducer 212 to rotate. The reducer 212 reduces the rotational speed and increases the output torque, enabling it to handle larger loads. Since the motor 211 typically rotates too fast, and the spindle box 500 to be installed is relatively heavy, the motor 211 cannot directly drive the spindle box 500 to rotate. Therefore, the reducer 212 is needed to reduce the rotational speed to meet the requirements and ensure the smooth rotation of the spindle box 500.

[0048] Preferably, motor 211 is a three-phase motor.

[0049] See Figure 9 The transmission assembly 220 includes a housing 221 and a transmission shaft 222 disposed within the housing 221. The housing 221 is mounted and connected to the support bracket 100. One end of the transmission shaft 222 is connected to the drive assembly 210, and the other end of the transmission shaft 222 is connected to the rotating bracket 231. The drive assembly 210 is used to drive the transmission shaft 222 to rotate, thereby causing the rotating bracket 231 to rotate.

[0050] Specifically, one end of the drive shaft 222 is connected to the reducer 212 of the drive assembly 210, and the other end of the drive shaft 222 is connected to the first rotating bracket 2311 of the rotating bracket 231. That is, the other end of the drive shaft 222 and the first rotating bracket 2311 are connected and locked together by eight M12-35 socket head cap bolts. When the motor 211 rotates, the reducer 212 reduces the rotational speed of the motor 211 and transmits the speed to the drive shaft 222, so that the drive shaft 222 and the reducer 212 rotate synchronously. The drive shaft 222 drives the rotating bracket 231 and the spindle box 500 mounted on the rotating bracket 231 to rotate synchronously.

[0051] Further, see Figure 1 and Figure 3The tooling mechanism also includes a control component 300, which is mounted on the support bracket 100 and electrically connected to the motor 211 for controlling the start and stop of the motor 211. When the control component 300 receives an start signal, it controls the motor 211 to start rotating, while the reducer 212 reduces the speed of the motor 211 and drives the transmission component 220 to rotate. The rotation of the transmission component 220 drives the rotating bracket 231 to start rotating, thereby achieving synchronous rotation of the spindle box 500 mounted on the rotating bracket 231.

[0052] Specifically, one end of the control component 300 is connected to the power supply, and the other end is connected to the motor 211.

[0053] The control component 300 includes a first button and a second button (not shown in the figure). The first button is electrically connected to both the motor 211 and the power supply, and the second button is also electrically connected to both the motor 211 and the power supply. It should be noted that the circuits of the first and second buttons are connected to the power supply in opposite directions to achieve circuit commutation for controlling the motor 211, enabling the motor 211 to switch between forward and reverse rotation. For example, the first button is a forward rotation button. When the installed spindle box 500 needs to be rotated forward, the first button can be pressed, the circuit is connected, and the motor 211 rotates forward. Releasing the first button disconnects the circuit, and the motor 211 stops rotating. The second button is a reverse rotation button. When the installed spindle box 500 needs to be rotated in the reverse direction, the second button can be pressed, the circuit is connected, and the motor 211 rotates in reverse. Releasing the second button disconnects the circuit, and the motor 211 stops rotating. In other words, when the control component 300 receives a control signal from the first button (i.e., the operator presses the first button), the control component 300 controls the motor 211 to rotate forward; when the control component 300 receives a control signal from the second button (i.e., the operator presses the second button), the control component 300 controls the motor 211 to rotate in reverse. Thus, the direction of the output shaft of the motor 211 can be adjusted through the control component 300, thereby achieving rotational adjustment of the mounted spindle box 500 in a specific direction.

[0054] Of course, in another embodiment, the first button is a reverse button. When it is necessary to rotate the installed spindle box 500 in the reverse direction, the first button can be pressed, the circuit is connected, and the motor 211 reverses. When the first button is released, the circuit is disconnected, and the motor 211 stops rotating. The second button is a forward button. When it is necessary to rotate the installed spindle box 500 in the forward direction, the second button can be pressed, the circuit is connected, and the motor 211 rotates forward. When the second button is released, the circuit is disconnected, and the motor 211 stops rotating. That is, when the control component 300 receives the control signal of the first button (i.e., the operator presses the first button), the control component 300 controls the motor 211 to reverse; when the control component 300 receives the control signal of the second button (i.e., the operator presses the second button), the control component 300 controls the motor 211 to rotate forward.

[0055] See also Figure 1 and Figure 3 The support bracket 100 includes a bottom bracket 110 and a mounting bracket 120. The area directly above the bottom bracket 110 is divided into a first region and a second region. The mounting bracket 120 is fixed to the first region, and a triangular roof structure is formed between the mounting bracket 120 and the bottom bracket 110 located in the first region. The rotary drive assembly is connected to the crossbeam of the triangular roof structure, that is, the rotary drive assembly is fixedly connected to the crossbeam of the triangular roof structure through the housing 221 of the transmission assembly 220. The second region is located on the side of the first region opposite to the mounting spindle box 500.

[0056] Furthermore, in this embodiment, the tooling mechanism also includes a counterweight 400, which is disposed on the bottom support 110 located in the second region B2. The purpose of the counterweight 400 in this embodiment is to balance the center of gravity of the tooling mechanism. When the spindle box 500 is installed, due to its large mass and its position at the front end of the entire tooling mechanism, it protrudes too much from the support points. Without the counterweight 400, the overall center of gravity might shift forward, posing a risk of the tooling mechanism tipping over. Placing the counterweight 400 in the second region B2 of the bottom support 110 ensures that after the spindle box 500 is installed, the overall center of gravity remains within the support points at both ends, avoiding the risk of the tooling mechanism tipping over.

[0057] This invention does not limit the material and weight of the counterweight 400, as long as it can balance the center of the tooling mechanism and prevent the tooling mechanism from tipping over after the spindle box 500 is installed.

[0058] In the actual assembly process, the various components of the spindle box 500 can be assembled simultaneously with the machine tool assembly using the tooling mechanism of this invention. After the machine tool assembly is completed, the operator can rotate the spindle box 500 on the tooling mechanism to the required assembly angle, gently lift the spindle box 500 using a crane, ensuring the lifting rope is taut, and then sequentially remove 16 M10-70 screws to detach the spindle box 500 from the tooling mechanism. Moving the crane, the spindle box 500 is moved to the machine tool. By adjusting the crane position and lifting height, the mounting holes of the spindle box 500 are aligned with the threaded holes on the machine tool, and the M10 screws are tightened with a torque wrench to install the spindle box 500 on the machine tool. Thus, the spindle box 500 can be assembled simultaneously with the machine tool assembly, and the assembled spindle box 500 can be directly assembled with the machine tool, reducing the process steps of assembling the spindle box 500 step-by-step on the machine tool and significantly shortening the assembly cycle. The mounting pad 232 effectively distinguishes between different specifications and models of spindle boxes 500, ensuring that different models of spindle boxes 500 can be correctly installed on the corresponding machine tools.

[0059] like Figure 10 and Figure 11 As shown, this utility model also provides an assembly device, including a spindle box 500 and a tooling mechanism for assembling the spindle box as described in any of the above embodiments. The spindle box 500 is detachably mounted on the rotating bracket 231.

[0060] This utility model also provides a CNC machine tool, including a tooling mechanism for assembling a spindle box as described in any of the above embodiments, or including the assembly device described above.

[0061] In summary, this utility model provides a tooling mechanism for assembling a spindle box. The spindle box is detachably mounted on a rotating bracket of this tooling mechanism. A drive assembly drives a transmission assembly to rotate, which in turn rotates the rotating bracket, causing the spindle box to rotate synchronously. This allows the spindle box to be rotated to the required installation position, making it easier for operators to assemble the spindle box onto the machine tool. Furthermore, multiple detachable mounting pads are provided on the rotating bracket. The spindle box is detached and mounted on the rotating bracket via these mounting pads. Operators can adapt the spindle box to different machine tool models by replacing different mounting pads. Moreover, when the threaded holes securing the spindle box wear due to repeated detachment and reassembly of the spindle box over a long period, simply replacing the mounting pads ensures the stability of the spindle box and rotating bracket installation, significantly reducing production costs.

[0062] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
