Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a double-layer motor double-slide structure. Background Technology

[0002] Existing motors have only one output shaft and can only mount one grinding wheel or other grinding tool. When grinding workpieces such as glass or stone, multiple motors (e.g., 10 or more) need to be installed sequentially on the side of the machine. Each grinding wheel is used in turn to perform various processes on the workpiece, such as rough polishing, fine polishing, grinding straight edges, grinding beveled edges, and grinding rounded edges. This motor layout results in a very long machine body, occupying a lot of factory space; the workpiece travel distance during processing is also very long, leading to low processing efficiency. Utility Model Content

[0003] In order to overcome at least one of the technical problems existing in the prior art, this utility model provides a double-layer motor double-slide structure, which can reduce the length of the processing machine body, occupy less factory space, shorten the stroke of the workpiece during processing, and increase the processing speed.

[0004] A double-layer motor double-slide structure includes a first electric spindle, a second electric spindle mounted side-by-side at the rear end of the first electric spindle, a first output shaft rotatably mounted on the first electric spindle (the first output shaft is a hollow shaft extending axially), and a second output shaft rotatably mounted on the second electric spindle (the second output shaft extends axially from the first output shaft). A grinding wheel is mounted at the output ends of both the first and second output shafts. A double-slide device is mounted at the lower ends of the first and second electric spindles, comprising a slide base and two slide plates slidably mounted on the slide base, arranged side-by-side. The first and second electric spindles are correspondingly fixed to the two slide plates. Two drive components are arranged side-by-side within the slide base. Each drive component includes a drive motor mounted at one end of the slide base. A lead screw is mounted on the output shaft of the drive motor, and the lead screw is rotatably connected to the slide base via a bearing. A nut seat is threaded onto the lead screw and fixed to the bottom of the slide plate. Two slots are formed in the slide base for the nut seat to move back and forth.

[0005] In some embodiments, a telescopic protective cover is installed between the two slide plates, which covers the top portion of the two slots.

[0006] In some embodiments, the telescopic protective cover has a U-shaped cross-section and a V-shaped groove on its surface.

[0007] In some embodiments, the drive motor is a servo motor, the lead screw is a ball screw, the bearing is a deep groove bearing, and the slot is a rectangular through hole.

[0008] In some embodiments, the first output shaft and the second output shaft are concentrically arranged, with a rotational gap between them; the two grinding wheels are concentrically arranged, with a rotational gap between them as well.

[0009] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0010] The first and second electric spindles are arranged side by side, one in front of the other. The second output shaft extends axially from the first output shaft. Each of the two output shafts can be equipped with a grinding wheel, which can reduce the length of the machine body and occupy less factory space. The workpiece has a shorter stroke during processing and the processing speed is faster.

[0011] The two drive components independently drive the first and second electric spindles to move back and forth, thereby achieving independent feeding of the first and second output shafts.

[0012] Additional aspects and advantages of this invention will continue to be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of this invention. Attached Figure Description

[0032] Reference Figures 1-7A double-layer motor double-slide structure includes a first electric spindle 1, a second electric spindle 2 mounted side-by-side at the rear end of the first electric spindle 1, a first output shaft 100 rotatably mounted on the first electric spindle 1 (the first output shaft 100 is a hollow shaft extending axially), and a second output shaft 200 rotatably mounted on the second electric spindle 2 (the second output shaft 200 extends axially from the first output shaft 100). A grinding wheel 121 is mounted at the output ends of both the first output shaft 100 and the second output shaft 200, and the two grinding wheels 121 are used to process workpieces. A double-slide device 3 is mounted at the lower ends of the first electric spindle 1 and the second electric spindle 2, which includes a slide base 300 slidably mounted on the slide base. Two sliding plates 301 are arranged side by side on the base 300. The first electric spindle 1 and the second electric spindle 2 are fixed on the two sliding plates 301 respectively. Two drive components 4 are arranged side by side in the left and right sides inside the base 300. Each drive component 4 includes a drive motor 400 installed at one end of the base 300. A lead screw 401 is installed on the output shaft of the drive motor 400. The lead screw 401 is rotatably connected to the base 300 through a bearing 402. A nut seat 403 is threaded on the lead screw 401. The nut seat 403 is fixed to the bottom of the sliding plate 301. Two slots 3001 are opened on the base 300 for the nut seat 403 to move back and forth.

[0033] In use, the first electric spindle 1 drives the first output shaft 100 and the grinding wheel 121 installed at the output end of the first output shaft 100 to rotate; the second electric spindle 2 drives the second output shaft 200 and the grinding wheel 121 installed at the output end of the second output shaft 200 to rotate. Both grinding wheels 121 can perform work on the workpiece. The first electric spindle 1 and the second electric spindle 2 are arranged side by side, roughly in a straight line. The above motor layout structure can reduce the length of the machine body and occupy less factory space; the workpiece has a shorter stroke during processing and the processing speed is faster.

[0034] When the drive motor 400 is working, it drives the lead screw 401 to rotate, and then causes the nut seat 403 to move forward or backward in a straight line within the slot 3001. When the nut seat 403 moves, the slide plate 301 and the first electric spindle 1 and the second electric spindle 2 mounted on the slide plate 301 move synchronously. The two drive components 4 drive the first electric spindle 1 and the second electric spindle 2 to move back and forth independently.

[0035] In some embodiments, a telescopic protective cover 5 is installed between two sliding plates 301, which covers the top portion of the two slots 3001. The telescopic protective cover 5, also known as a telescopic protective cover or guide rail protective cover, is a flexible protective device used to protect moving parts such as mechanical guide rails, lead screws, and bearings. Its folding structure is similar to an accordion, allowing it to extend and retract freely with the moving parts of the equipment. It consists of multiple layers of folded sheets (usually strips or plates) connected by hinges or adhesives to form a telescopic corrugated structure. Both ends are fixed to the stationary and moving ends of the equipment by flanges or metal frames. The telescopic protective cover 5 can prevent contaminants such as chips, dust, and coolant from entering the precision moving parts, protect internal components from damage caused by external impacts or splashes, reduce friction and corrosion, and lower the frequency of equipment maintenance.

[0036] In some embodiments, the telescopic protective cover 5 has a U-shaped cross-section, which can effectively surround the top and sides of the tray base 300, and its surface is provided with a V-shaped groove 500 to facilitate liquid outflow.

[0037] In some embodiments, the drive motor 400 is a servo motor. The servo motor closed-loop feedback system can achieve positioning accuracy of ±0.01mm, which is suitable for precision machining. It can start and stop quickly, has high acceleration, improve equipment efficiency, and avoid stalling or overload through real-time torque adjustment, thus extending the life of the lead screw. The lead screw 401 is a ball screw with low friction coefficient, high transmission efficiency, high repeatability, minimal rolling friction wear, and long life. The bearing 402 is a deep groove bearing, which is compatible with both radial and axial bidirectional loads. Its sealed design prevents dust and oil leakage and has a long lubrication-free cycle. The slot 3001 is a rectangular through hole that matches the shape and size of the nut seat 403, facilitating the back-and-forth movement of the nut seat 403.

[0038] In some embodiments, the first output shaft 100 and the second output shaft 200 are concentrically arranged, with a rotational clearance between them; the two grinding wheels 121 are also concentrically arranged, with a rotational clearance between them. This structure ensures that the operation of the two output shafts and the two grinding wheels 121 is undisturbed, and also improves machining accuracy.

[0039] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
