Description

Technical Field

[0001] This utility model relates to the field of motor installation technology, and in particular to a motor installation structure for CNC machine tools. Background Technology

[0002] A CNC machine tool is a device for machining workpieces. Inside a CNC machine tool, a motor drives the spindle to rotate, and the spindle drives the cutting tool on it to rotate to perform the work.

[0003] Motors in CNC machine tools are generally fixed to the mounting plate inside the machine tool by bolts. The bolts pass through the base plate at the bottom of the motor and are then screwed into the mounting plate to complete the motor installation. In order to facilitate motor installation, the base plate at the bottom of the motor is generally provided with a slot. The bolts can be moved in the slot to align with the mounting plate, so that the motor can be used in different installation positions.

[0004] However, with the slotted design, the bolts are prone to loosening during motor operation. The loosened bolt knobs no longer tightly press against the top of the motor's bottom plate, thus preventing the bolts from effectively securing the motor and causing it to shift, reducing the stability of the motor installation. To address this, we propose a motor mounting structure for CNC machine tools. Utility Model Content

[0005] The purpose of this utility model is to provide a motor mounting structure for CNC machine tools to solve the problems mentioned in the background art.

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-4 The diagram shows a motor mounting structure for a CNC machine tool, including a motor body 101 and a positioning mechanism. A mounting assembly is provided at the bottom of the motor body 101, which mounts the motor body 101, enabling stable operation. The mounting assembly includes a base plate 103, which is fixedly connected to the bottom of the motor body 101. A mounting plate 102 is located below the base plate 103, and a fixing mechanism is provided between the base plate 103 and the mounting plate 102. The fixing mechanism includes fixing bolts 304. A slotted groove 302 is formed at the top of the base plate 103, and the fixing bolts 304 are inserted into the inner wall of the slotted groove 302. A threaded hole 303 is formed at the top of the mounting plate 102, and the outer wall of the fixing bolts 304 is threadedly connected to the inner wall of the threaded hole 303. By tightening the fixing bolts 304 through the slotted groove 302 and into the threaded hole 303, the base plate 103 is fixed to the mounting plate 102, allowing the motor body 101 to operate stably.

[0024] In a preferred embodiment, a positioning mechanism is disposed above the mounting assembly. The positioning mechanism includes a connecting pad 201. A first rack 202 is symmetrically fixedly connected to the bottom end of the connecting pad 201, and a second rack 203 is symmetrically fixedly connected to the top end of the mounting assembly. The outer wall of the first rack 202 meshes with the outer wall of the second rack 203. A pressing mechanism is provided at the top end of the connecting pad 201. An insertion hole 301 is opened at the top end of the connecting pad 201. The outer wall of the fixing bolt 304 is movably inserted into the inner wall of the insertion hole 301. When installing the motor body 101, the motor body 101 is placed at the desired position at the top end of the mounting plate 102, and then the fixing bolt 304 is inserted into the connecting pad. The connecting pad 201 is inserted into the insertion hole 301 of the plate 201, then inserted into the strip groove 302, and finally screwed into the threaded hole 303. As the fixing bolt 304 is continuously turned down, the top of the connecting pad 201 is squeezed by the knob of the fixing bolt 304, which causes the connecting pad 201 to descend until the first rack 202 and the second rack 203 are tightly engaged, completing the installation of the motor body 101 and fixing the connecting pad 201 to the base plate 103. This also fixes the fixing bolt 304 to the base plate 103, so that when the motor body 101 is working, there will be no relative movement between the fixing bolt 304 and the base plate 103, thereby improving the stability of the motor body 101 installation.

[0025] The compression mechanism includes a compression washer 401. An annular groove 402 is formed at the top of the connecting pad 201. The outer wall of the compression washer 401 is slidably connected to the inner wall of the annular groove 402. An elastic mechanism is provided inside the annular groove 402, including multiple compression springs 501. The compression springs 501 are located inside the annular groove 402 and at the bottom end of the compression washer 401. A limiting mechanism is provided between the compression washer 401 and the connecting pad 201. Through the elastic action of the compression springs 501, and by limiting the bottom end of the compression springs 501 through the bottom end of the annular groove 402, the compression springs 501 continuously compress the compression washer 401 upwards, thus giving the compression washer 401 a continuous upward tendency. This allows the fixing bolt 304 to pass through the insertion hole 301 and the strip groove 302 sequentially and be screwed into the threaded hole 30. During step 3, the knob of the fixing bolt 304 first squeezes the compression washer 401, causing the compression washer 401 to descend until the fixing bolt 304 tightly abuts against the top of the connecting pad 201, completing the installation of the motor body 101. At this time, the compression washer 401 is completely retracted into the annular groove 402. The descent of the compression washer 401 will continue to compress the compression spring 501, causing the compression spring 501 to continuously press the compression washer 401 upward, which in turn causes the compression washer 401 to continuously press the bottom end of the knob of the fixing bolt 304 upward. This results in the fixing bolt 304 being continuously subjected to upward compressive force, making the outer wall of the fixing bolt 304 mesh more closely with the inner wall of the threaded hole 303. This makes the fixing bolt 304 less prone to loosening within the threaded hole 303, thereby improving the stability of the installation of the motor body 101 and ensuring the stable operation of the motor body 101.

[0026] The limiting mechanism includes a limiting block 602, one side of which is fixedly connected to the bottom end of the outer wall of the extrusion washer 401. A limiting groove 601 is formed in the inner wall of the annular groove 402. The outer wall of the limiting block 602 is slidably connected to the inner wall of the limiting groove 601. By limiting the limiting block 602 through the limiting groove 601, the movement of the extrusion washer 401 can be restricted, so that the extrusion washer 401 cannot be separated from the annular groove 402. This improves the working stability of the extrusion washer 401 and prevents the extrusion washer 401 from popping out of the annular groove 402 under the compression of the compression spring 501, thus ensuring the stable operation of the extrusion mechanism.

[0027] In this design, a limiting rod 701 is fixedly connected to the bottom end of the inner wall of the annular groove 402, and a limiting hole 702 is opened at the bottom end of the compression washer 401. The outer wall of the limiting rod 701 is movably inserted into the inner wall of the limiting hole 702. The compression spring 501 is sleeved on the outer wall of the limiting rod 701. Through the limiting hole 702 and the limiting guide of the limiting rod 701, the compression washer 401 can move stably within the annular groove 402. At the same time, the limiting rod 701 can limit the compression spring 501, so that the compression spring 501 will not deform laterally when it is compressed by the compression washer 401 descending. This improves the working stability of the compression spring 501 and prevents the compression spring 501 from deforming and no longer compressing the compression washer 401 upward, thus improving the working stability of the elastic mechanism.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
