Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, specifically to a main motor mounting structure for a horizontal lathe. Background Technology

[0002] Small horizontal lathes typically include components such as a spindle and a motor. The motor primarily serves as the drive component for the spindle and is mounted on the lathe's machining platform via a motor mount. Since the motor mount is usually an independently arranged structure, the parallelism between the motor and the spindle axis needs to be manually adjusted during installation to ensure smooth operation of the pulleys and belts. However, manual adjustment usually requires specialized tooling such as a laser alignment instrument; otherwise, it is difficult to adjust the parallelism between the motor and the spindle axis to an ideal state, which can subsequently cause abnormal vibration and abnormal belt wear, affecting accuracy and the lifespan of components. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a main motor mounting structure for a horizontal lathe, thereby solving the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

A positioning seat is also provided on the rear side of the spindle housing. The positioning seat and the spindle housing are integrally formed. The top of the positioning seat is a first positioning plane, and the axis of the spindle is parallel to the first positioning plane. The rear side of the positioning seat is a second positioning plane, and the axis of the spindle is perpendicular to the second positioning plane. A motor mount is mounted on the positioning seat, and the motor mount is tightly fitted with the first and second positioning planes respectively. A motor is mounted on the motor mount, and the motor is connected to the spindle via a transmission assembly.

[0006] As a preferred embodiment of the main motor mounting structure for a horizontal lathe, the transmission assembly includes a driving pulley, a driven pulley, and a belt. The output shaft of the motor is connected to the driving pulley, and the rear side of the main shaft is connected to the driven pulley. The driving pulley and the driven pulley are connected by belt drive.

[0007] As a preferred embodiment of the main motor mounting structure for a horizontal lathe, an adjustment component is installed at one end of the positioning seat. The adjustment component is connected to the motor seat and is used to adjust the position of the motor seat.

[0008] As a preferred embodiment of the main motor mounting structure of a horizontal lathe, the adjustment assembly includes an adjustment block and an adjustment bolt. The adjustment block is mounted on the positioning seat and has a first threaded hole. The motor seat has a second threaded hole on the side near the adjustment block. The adjustment bolt passes through the first threaded hole and is threadedly connected to the second threaded hole of the motor seat.

[0009] As a preferred embodiment of the main motor mounting base structure for a horizontal lathe, the bottom of the motor base is a first mounting surface. The first mounting surface is provided with a plurality of first adjustment elongated holes spaced apart along its length. The first positioning plane of the positioning base is provided with a first connecting hole at the position corresponding to the first adjustment elongated holes. The first adjustment elongated holes extend along their length, such that the length of the first adjustment elongated holes is greater than the diameter of the first connecting holes. The first adjustment elongated holes and the first connecting holes are connected by fasteners.

[0010] As a preferred embodiment of the main motor mounting structure of a horizontal lathe, the rear bottom of the motor base extends downward to form a second mounting surface.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0023] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 3 As shown, this utility model provides a main motor mounting structure for a horizontal lathe, including a spindle housing 1, on which a spindle 2 is movably mounted. A positioning seat 3 is also provided on the rear side of the spindle housing 1. In this embodiment, the positioning seat 3 and the spindle housing 1 preferably adopt an integral molding structure design. The parallelism between the positioning seat 3 and the axis of the spindle 2 is controlled and ensured by machining. The top of the positioning seat 3 is a first positioning plane 31, and the axis of the spindle 2 is parallel to the first positioning plane 31. The rear side of the positioning seat 3 is a second positioning plane 32, and the axis of the spindle 2 is perpendicular to the second positioning plane 32. A motor seat 4 is mounted on the positioning seat 3, and a motor 5 is mounted on the motor seat 4. The motor 5 can be installed without any auxiliary instruments. Simply place the motor seat 4 tightly against the first positioning plane 31 and the second positioning plane 32 of the positioning seat 3 and lock it with bolts. This structure significantly improves assembly efficiency, provides high precision and stability after installation, effectively reduces the risk of subsequent equipment failure, and extends the service life of parts.

[0026] Meanwhile, motor 5 is connected to main shaft 2 via transmission assembly 6, and the preferred transmission connection method is as follows:

[0027] The output shaft of motor 5 is connected to a drive pulley 61, and the rear side of main shaft 2 is connected to a driven pulley 62. The drive pulley 61 and the driven pulley 62 are connected by a belt 63. When motor 5 starts, motor 5 will drive drive pulley 61 to rotate. Drive pulley 61 drives driven pulley 62 to rotate through belt 63, and finally drives main shaft 2 to rotate.

[0028] It is understood that the front side of the spindle 2 in this embodiment is used to install a fixture to facilitate the processing of the workpiece, while the rear side of the spindle 2 is used to install the transmission assembly 6. The rear side of the spindle housing 1 in this embodiment is the side closer to the transmission assembly 6.

[0029] To facilitate the adjustment of the tension of the belt 63, an adjustment component 7 is installed at one end of the positioning seat 3 in this embodiment. The adjustment component 7 is connected to the motor seat 4. By rotating the adjustment component 7, the horizontal position of the motor seat 4 can be adjusted, thereby achieving the purpose of adjusting the tension of the belt 63.

[0030] Specifically, the adjustment component 7 in this embodiment includes an adjustment block 71 and an adjustment bolt 72. The adjustment block 71 is installed on the positioning seat 3 and has a first threaded hole. The motor seat 4 has a second threaded hole on the side near the adjustment block 71. The adjustment bolt 72 passes through the first threaded hole and is threadedly connected to the second threaded hole of the motor seat 4. When the adjustment bolt 72 rotates, it will drive the motor seat 4 to move horizontally.

[0031] like Figure 4 and Figure 5 As shown, to improve the stability of the motor base 4, the bottom of the motor base 4 in this embodiment is set as a first mounting surface 41. The first mounting surface 41 is provided with a plurality of first adjustment elongated holes 42 at intervals along its length direction. The first positioning plane 31 of the positioning seat 3 is provided with a first connecting hole 33 at the position corresponding to the first adjustment elongated holes 42. The first adjustment elongated holes 42 extend along their length direction, so that the length of the first adjustment elongated holes 42 is greater than the diameter of the first connecting hole 33. After the horizontal position of the motor base 4 is adjusted by adjusting bolts 72, the first mounting surface 41 of the motor base 4 is tightly attached to the first positioning plane 31, and the first adjustment elongated holes 42 and the first connecting holes 33 are connected by fasteners, thereby fixing the motor base 4 on the positioning seat 3.

[0032] To further improve the stability of the motor base 4, the rear bottom of the motor base 4 in this embodiment extends downward to form a second mounting surface 43. The second mounting surface 43 has a plurality of second adjustment elongated holes 44 along its length direction. The second positioning plane 32 of the positioning seat 3 has a second connecting hole 34 corresponding to the position of the second adjustment elongated hole 44. The second adjustment elongated hole 44 extends along its length direction, such that the length of the second adjustment elongated hole 44 is greater than the diameter of the second connecting hole 34. When the motor base 4 is installed, the second adjustment elongated hole 44 can also be connected to the second connecting hole 34 by fasteners to fix the first mounting surface 41 and the second mounting surface 43 of the motor base 4, which can further improve the stability.

[0033] Preferably, in this embodiment, the lengths of the first adjusting elongated hole 42 and the second adjusting elongated hole 44 are consistent with the adjustment range of the adjusting bolt 72, thereby ensuring that after the adjusting bolt 72 adjusts the motor base 4, the first adjusting elongated hole 42 and the second adjusting elongated hole 44 can be connected to the first connecting hole 33 and the second connecting hole 34.

[0034] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
