[0002] In the field of spindle machining equipment technology, the motor spindle is a core functional component, and its assembly, debugging, and performance testing are crucial. To meet the machining and testing needs of spindles of different specifications and models, the support device needs to have high adaptability and flexibility, and be able to quickly and accurately adjust the support position and height to ensure that the spindle is in the best working condition and to ensure the stability and efficiency of the transmission system (such as belt drive). Traditional fixed support seats are no longer suitable for the modern flexible and multi-variety production rhythm. Therefore, developing a universal support device that can be adjusted with multiple degrees of freedom has become the key to improving production efficiency and product quality.

[0003] Traditional motor spindle machining support fixtures often employ fixed spacing or structures that can only perform coarse adjustments in a single dimension. When dealing with spindles of different shaft diameters and center distances, they typically require replacing the entire fixture or performing tedious manual adjustments. This results in problems such as low adjustment accuracy, time-consuming and labor-intensive processes, and poor versatility. Furthermore, traditional adjustment methods often fail to effectively maintain the optimal tension of the transmission belt after adjusting the spindle position, which can easily lead to decreased transmission efficiency and belt wear. Therefore, we propose an adjustable motor spindle support device to solve the above problems. Utility Model Content

[0015] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 — Figure 3 An adjustable motor spindle support device includes a base 1, a drive seat 2 fixedly installed at the center of the upper part of the base 1, a drive wheel 3 installed on the front end face of the drive seat 2, a drive motor 4 fixed on the rear end face of the drive seat 2, sliding grooves 6 fixed on both sides of the upper end face of the base 1, a convex block 7 slidably sleeved in the inner cavity of the sliding groove 6, a movable plate 8 fixed on the upper end face of the convex block 7, threaded rods 9 threadedly engaged on both sides of the movable plate 8, a threaded sleeve 10 fixed on the lower end face of the movable plate 8, lead screws 11 rotatably installed on both sides of the upper end face of the base 1, servo motors 12 fixed on both sides of the base 1, and a workstation assembly 13 installed on the upper end face of the movable plate 8. The output shaft of the drive motor 4 passes through the drive seat 2 and is connected to the drive wheel 3 to provide power. The drive wheel 3 establishes a transmission connection with the workstation spindle 14 through the transmission belt 5, thereby transmitting power to the workstation spindle 14. Through the synchronous or independent control of two servo motors 12, the lead screws 11 on both sides can be driven to rotate synchronously, thereby driving the two moving plates 8 to move towards or away from each other along the slide 6, realizing the precise and automatic adjustment of the center distance between the spindles 14 at the work station. The threaded rod 9 is used to lock the convex block 7 after the position adjustment is completed to prevent it from shifting during the processing and ensure the rigidity of the support. The workstation assembly 13 includes two vertical plates 1301 mounted on the upper surface of the movable plate 8. The vertical plates 1301 have a waist groove 1302 inside. The rear end face of the vertical plates 1301 is movably connected to an assembly plate 1303, and a rotating shaft 1304 is rotatably mounted on the surface of the assembly plate 1303. The front end face of the vertical plates 1301 is fitted with a fastening bolt 1305. The rear end face of the assembly plate 1303 is movably connected to a handle nut 1306. The upper end face of the rotating shaft 1304 is movably connected to the workstation spindle 14. The waist groove 1302 is a vertically elongated through hole, which provides guidance and travel space for the vertical position adjustment of the assembly plate 1303; Loosening the handle nut 1306 allows the fastening bolt 1305 to slide within the groove 1302, thereby enabling continuous vertical height adjustment of the entire assembly plate 1303 and the workstation spindle 14. After adjusting to the required height, tightening the handle nut 1306 fixes the position. This structure effectively compensates for the looseness of the transmission belt 5 caused by changes in spindle height and allows for adaptation to different processing requirements.

[0017] Furthermore, the threaded rod 9 passes through the convex block 7 and is movably connected to the inner cavity of the slide groove 6 to fasten the convex block 7 inside the slide groove 6.

[0018] Furthermore, the output end of the servo motor 12 is connected to the lead screw 11 for driving the lead screw 11 to rotate.

[0019] Furthermore, the threaded sleeve 10 engages with the threaded screw 11, and the moving plate 8 forms a linearly movable structure through the threaded sleeve 10 and the threaded screw 11.

[0020] Furthermore, the fastening bolt 1305 passes through the waist groove 1302, the assembly plate 1303, and is assembled and connected to the handle nut 1306.

[0021] Furthermore, the assembly plate 1303 forms an assemblable structure with the vertical plate 1301 via fastening bolts 1305.

[0022] Furthermore, a transmission belt 5 is installed between the drive wheel 3 and the main shaft 14 of the workstation; This device achieves precise electric adjustment of the horizontal center distance of the spindle at the workstation through a servo motor and a lead screw and nut mechanism, while the spindle height is conveniently adjusted manually through a waist groove and fastening bolt mechanism. Together, they form a motor spindle support solution that is flexible in adjustment, precise in positioning, and rigidly reliable, and is particularly suitable for processing scenarios with multiple spindles and multiple specifications of workpieces.

[0023] Working principle: In use, the core of the adjustable motor spindle support device lies in its precise horizontal and vertical adjustment function and stable power transmission. When the device is started, the drive motor 4 works, and its output shaft drives the drive wheel 3 to rotate. The drive wheel 3 transmits power synchronously to the two spindles 14 at the two workstations through the transmission belt 5, enabling them to obtain the rotational motion required for cutting. When the horizontal center distance between the two spindles 14 needs to be adjusted to accommodate different work sizes, the system activates the horizontal adjustment mode. The servo motors 12 on both sides receive the command and rotate synchronously, driving the lead screw 11 connected to them to rotate. Since the threaded sleeve 10, which is threadedly engaged with the lead screw 11, is fixed to the bottom of the moving plate 8, and the convex block 7 at the bottom of the moving plate 8 is restricted to linear sliding within the slide groove 6, the rotational motion of the lead screw 11 is converted into linear motion of the moving plate 8 and the entire work station assembly 13 above it, either towards or away from each other. This process achieves precise and automatic adjustment of the distance between the two spindles 14. After the horizontal position is adjusted to the correct position, the threaded rods 9 on both sides of the moving plate 8 can be tightened. The front end of the threaded rod 9 will press against the inner wall of the slide groove 6, thereby locking the position of the convex block 7 and providing additional mechanical locking for the entire moving part, preventing displacement during processing vibration and ensuring the rigidity of the support. When fine adjustment of the work station spindle is required, the system can be adjusted accordingly. When adjusting the vertical height of shaft 14 to accommodate different workpieces or compensate for the tension of transmission belt 5, the vertical adjustment mechanism is operated. First, the handle nut 1306 at the front end of vertical plate 1301 is loosened, so that the fastening bolt 1305 is in a sliding state within the groove 1302 of vertical plate 1301. The groove 1302 serves as a guide channel in the vertical direction, allowing the entire assembly plate 1303, along with the rotating shaft 1304 and the main shaft 14 of the workstation, to move continuously up and down. After adjusting the height to the appropriate position, the handle nut 1306 is tightened again, and the assembly plate 1303 is firmly clamped and fixed to vertical plate 1301 by fastening bolt 1305, thus completing the height positioning and fixing. This vertical adjustment can not only adapt to the clamping height of different workpieces, but also effectively compensate for the possible loosening of transmission belt 5 due to changes in horizontal center distance or long-term use, ensuring the efficiency and stability of power transmission. This completes the working principle of this utility model.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
