Technical Field

[0001] The utility model relates to the technical field of the direct-drive motorized spindle of a CNC lathe, in particular to a combined direct-drive motorized spindle of a CNC lathe. Background Art

[0002] The direct-drive motorized spindle of a CNC lathe is the main component of a CNC machine tool for transmitting driving force and realizing workpiece rotation or cutting. It usually consists of a spindle box, a spindle gear transmission system, a spindle drive system, a spindle cooling system, etc. These systems work together to ensure the stable and precise operation of the spindle.

[0003] When it is necessary to connect the direct-drive motorized spindle with the motor output shaft, a positioning pin is generally used. First, the positioning pin is inserted into the corresponding position of the direct-drive motorized spindle, and then it is fixed by hitting with a hammer.

[0004] However, when it is necessary to use a hammer to strike, the striking force needs to be controlled. If the striking force is too large, the motorized spindle and the positioning pin will be damaged. If the striking force is too small, the positioning pin will not be firmly fixed, and multiple strikes will be required. Moreover, when a batch of motorized spindles needs to be replaced, the motorized spindles will be placed aside. When there are too many motorized spindles, they are likely to be lost. Therefore, a combined direct-drive motorized spindle is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a combined direct-drive motorized spindle, aiming to improve the problem that it is difficult to control the striking force when fixing the positioning pin in the prior art.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0033] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a combined direct-drive motorized spindle, including a shaft body 1. The shaft body 1 is a direct-drive motorized spindle. A connecting ring 2 is fixedly connected to the outer arc surface of the shaft body 1. The setting of the connecting ring 2 facilitates the connection of the shaft body 1 with other shafts. This is the prior art and will not be explained in detail here. A moving mechanism 3 is arranged on the inner wall of the shaft body 1; the moving mechanism 3 includes a rotating ring 301. A connecting plate 302 is fixedly connected to the outer arc surface of the rotating ring 301, and their movement trajectories are the same. A screw 303 is threadedly connected to the inner wall of the connecting plate 302. The screw 303 can play a role in fixing and limiting the rotating ring 301. A moving column 306 is slidably connected to the inner wall of the shaft body 1. A square plate is arranged at the bottom of the moving column 306. A positioning pin 304 is fixedly connected to the top end of the moving column 306, and their movement trajectories are the same. A connecting mechanism 4 is arranged on the outer wall of the connecting ring 2. The connecting mechanism 4 can quickly splice two groups of shaft bodies 1.

[0034] Refer to Figures 2 - 4, a protrusion is provided at the rear end of the rotating ring 301. The outer wall of the rotating ring 301 is rotatably connected to the inner wall of the shaft body 1. The protrusion is provided to prevent the rotating ring 301 from falling off during rotation. By rotating the rotating ring 301, the positioning pin 304 can be driven to move. A plurality of screw holes are provided at the front end of the shaft body 1. The rear end of the screw 303 is threadedly connected to the inner wall of the screw hole. The setting of the plurality of screw holes can make the exposed distances of the positioning pins 304 different, so as to adapt to the connection of different shafts. An arc-shaped groove 305 is provided on the outer wall of the rotating ring 301. The number of the arc-shaped grooves 305 is the same as the number of the movable columns 306. The outer wall of the movable column 306 is in contact with the inner wall of the arc-shaped groove 305. The outer wall of the positioning pin 304 is slidably connected to the inner wall of the shaft body 1. The setting of the arc-shaped groove 305 enables the rotation of the rotating ring 301, so that the movable column 306 moves, playing a guiding role.

[0035] Refer to Figures 3 - 5 , the connecting mechanism 4 includes a support block 402. The left end of the support block 402 is fixedly connected to the right end of the connecting ring 2. Through the connecting ring 2, the support block 402 can be supported. A plug-in plate 401 is fixedly connected to the left end of the connecting ring 2. Through the connecting ring 2, the plug-in plate 401 can be supported. The inner wall of the support block 402 is elastically connected with a plug-in column 403 through a connecting spring 404. The plug-in column 403 penetrates and is slidably connected to the inner wall of the support block 402. The penetrating setting facilitates manual movement to release the limit. The outer wall of the plug-in plate 401 is plugged into the inner wall of the support block 402. The plugging of the two can facilitate the connection of multiple shaft bodies 1. One end of the connecting spring 404 is fixedly connected to the outer wall of the plug-in column 403, and the other end of the connecting spring 404 is fixedly connected to the inner wall of the support block 402. The outer wall of the plug-in column 403 is slidably connected to the inner wall of the support block 402. Due to the elasticity of the connecting spring 404, the plug-in column 403 has the functions of resetting and limiting. And a slope is provided at the bottom end of the plug-in column 403, with the slope facing right. The bottom end of the plug-in column 403 is plugged into the inner wall of the plug-in plate 401, and the plugging of the two avoids the plugging limit and fixing effect.

[0036] Working principle: When relevant personnel need to install and fix the shaft body 1 of the direct-drive motorized spindle and the corresponding motor output shaft, first select a screwdriver corresponding to the screw 303, then insert the screwdriver into the screw 303, and then rotate the screwdriver to loosen the screw 303 and release the limit of the screw 303. Then, the rotating ring 301 can be rotated to drive the arc-shaped groove 305 to rotate, so that the movable column 306 moves, thereby moving the positioning pin 304 and protruding from the inner wall of the shaft body 1. In this way, the positioning pin 304 can be inserted and positioned with the hole on the motor output shaft.

[0037] When disassembling the electric spindle bodies 1 on multiple Swiss-type lathes, the disassembled multiple spindle bodies 1 can be fixed. The fixing operation is to insert the plugging plate 401 into the support block 402. When the two are plugged, the outer wall of the plugging plate 401 contacts and presses the inclined surface of the plugging column 403, so that the plugging column 403 moves upward. When the plugging plate 401 is completely plugged into the support block 402, at this time, due to the elasticity of the connecting spring 404, the plugging column 403 is plugged with the plugging plate 401 to complete the limit, thus completing the fixing operation.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
