A machine tool that can provide modular drive sources

Abstract

A modular drive source machine includes a base and a crossbeam. The base includes two columns and a transmission plate disposed between the two columns. Each column is provided with an outer slide rail, and the transmission plate is provided with two inner slide rails spaced apart. A connecting part is provided between the two inner slide rails. The crossbeam is mounted on the base. The bottom of the crossbeam is provided with two inner sliders and two outer sliders. Each inner slider and each outer slider slides on the inner slide rail and each outer slide rail respectively, so that the crossbeam can be displaced relative to the base. A first reference surface is formed on the front side of the crossbeam, and a positioning block is provided at the position corresponding to each inner slider. The top surface of the positioning block forms a second reference surface, which is perpendicular to the first reference surface. This allows a screw drive device to be directly installed on the base, or a screw drive device to be installed with a wire extension bracket. In this way, two different drive methods can be used on the same machine, achieving multiple uses and improving the convenience of use.

Description

A machine tool that can provide modular drive sources Technical Field

[0001] This work relates to a type of machine tool, specifically a machine tool that can provide modular drive sources. Prior Technology

[0002] Note that machine tools are machines used to manufacture machines and machinery. They mainly include lathes, milling machines, planers, drilling machines, boring machines, grinding machines, and gear cutting machines. These machines are used to process blanks or workpieces of metal or other materials to obtain the required shape, size, and surface quality.

[0003] The existing machine tools mainly use two types of drive sources: screw drive and linear motor drive. Referring to Figure 10, a machine tool 1 is disclosed that uses a screw 2 as the drive source. This means that by rotating the screw 2, the nut seat 3 can move along the threaded section of the screw, thereby driving the crossbeam 4 above it to produce linear motion. Referring to Figure 11, another machine tool 5 is disclosed that uses a linear motor 6 as the drive source. This means that by generating a changing magnetic field through the motor magnet 7, the crossbeam 8 located above the linear motor 6 achieves precise linear motion through the attraction and repulsion between the magnetic poles of the motor magnet 7 and the linear motor 6.

[0004] However, all of the aforementioned machine tools, regardless of their drive method, are single-unit designs. If users wish to use two different drive methods simultaneously, they must purchase two machines. This not only wastes production costs but also occupies space, causing limitations or inconvenience in use.

[0005] In view of this, the creator, based on years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above objectives, and finally created a work that is truly practical. Summary of the Invention

[0006] This invention discloses a machine tool that can provide a modular drive source, comprising: a base, the base including two symmetrically arranged columns, and a transmission plate disposed between the two columns. The top surface of the transmission plate is provided with two inner slide rails spaced apart, and a joint is provided between the two inner slide rails; a crossbeam, the crossbeam being assembled on the base, the bottom of the crossbeam being provided with two inner sliders, each inner slider sliding on its respective inner slide rail, so that the crossbeam can generate a front-back displacement relative to the base, and the front side of the crossbeam forming a first reference surface, and a positioning block being provided at the position corresponding to each inner slider, the top surface of the positioning block forming a second reference surface, the second reference surface being perpendicular to the first reference surface.

[0007] It also includes a screw drive device, which is located at the joint of the base. The screw drive device includes a motor, a bearing housing, a screw and a nut seat. The motor is connected to the bearing housing. One end of the screw is connected to the bearing housing and the other end is connected to the nut seat. The nut seat is fixed to the crossbeam.

[0008] It also includes a wire horse extension seat, which is fixed to the front side of the crossbeam. The rear side of the wire horse extension seat forms a first positioning surface and a second positioning surface that are perpendicular to each other. The first positioning surface abuts against the first reference surface, and the second positioning surface abuts against the second reference surface. The wire horse extension seat has a set of connecting parts and two extension parts. The two extension parts are connected to the two sides of the set of connecting parts. A slider is provided below each extension part, and each slider slides on the inner slide rail.

[0009] It also includes a linear motor drive device, which includes a linear motor magnet, a linear motor and a linear motor adapter plate. The linear motor magnet is assembled at the joint of the base, and the linear motor is fixed to the bottom of the joint of the linear motor extension seat through the linear motor adapter plate.

[0010] With the above structure, this invention has a connecting part on the transmission plate, and the front side of the crossbeam forms the first reference surface and the top surface of the positioning block forms the second reference surface. This allows the screw drive device to be directly installed on the base, or the screw drive device to be installed with the wire extension seat. In this way, two different drive methods can be used on the same machine tool, achieving multiple uses in one machine, thereby reducing production costs and space requirements, and improving ease of use.

[0023] Please refer to Figures 1 to 4, which are preferred embodiments of this invention, disclosing a machine tool 100 that can provide a modular drive source, comprising:

[0024] A base 10 includes two symmetrically arranged columns 11 and a transmission plate 12 disposed between the two columns 11. Each column 11 has an outer slide rail 111 on its top surface and two inner slide rails 121 spaced apart on its top surface. A joint 122 is disposed between the two inner slide rails 121.

[0025] A crossbeam 20 is assembled on the base 10. The bottom of the crossbeam 20 is provided with two inner sliders 21 and two outer sliders 22. Each inner slider 21 is slidably mounted on its respective inner slide rail 121. Each outer slider 22 is located outside its respective inner slider 21 and is slidably mounted on its respective outer slide rail 111, so that the crossbeam 20 can be displaced in the front and rear directions relative to the base 10. The front side of the crossbeam 20 forms a first reference surface 23, and a positioning strip 24 is provided at the position corresponding to each inner slider 21. The top surface of the positioning strip 24 forms a second reference surface 241, which is perpendicular to the first reference surface 23.

[0026] A hardware limit switch 25 is provided on the side of the crossbeam 20 near one of the inner sliders 21 and the positioning block 24 to detect and control the movement range and position of the crossbeam 20.

[0027] A screw drive device 30 is provided at the joint portion 122 of the base 10. The screw drive device 30 includes a motor 31, a bearing housing 32, a screw 33, and a nut seat 34. The motor 31 is connected to the bearing housing 32. One end of the screw 33 is connected to the bearing housing 32, and the other end is connected to the nut seat 34. The nut seat 34 is fixed to the crossbeam 20. Thus, when the motor 31 drives the bearing housing 32 to operate, it will drive the screw 33 to rotate, so that the nut seat 34 and the crossbeam 20 can be displaced in the front-back direction relative to the base 10.

[0028] To further understand the structural features, technical means employed, and intended effects of this work, its usage will be described below. This will provide a deeper and more concrete understanding of the work.

[0029] Referring to Figures 5 to 9, another embodiment of the invention is disclosed, which differs from the aforementioned preferred embodiment in that a line horse extension seat 40 is fixedly connected to the front side of the crossbeam 20. The rear side of the line horse extension seat 40 forms a first positioning surface 401 and a second positioning surface 402 that are perpendicular to each other. The first positioning surface 401 abuts against the first reference surface 23, and the second positioning surface 402 abuts against the second reference surface 241. The line horse extension seat 40 has a connecting portion 41 and two extension portions 42. The two extension portions 42 are connected to both sides of the connecting portion 41. A slider 421 is provided below each extension portion 42, and each slider 421 slides on the respective extension portion 42. The inner slide rail 121 does not have the screw drive device 30, but instead has a linear motor drive device 50. The linear motor drive device 50 includes a linear motor magnet 51, a linear motor 52, and a linear motor adapter plate 53. The linear motor magnet 51 is assembled at the joint 122 of the base 10. The linear motor 52 is fixed to the bottom of the joint 41 of the linear motor extension seat 40 through the linear motor adapter plate 53. In this way, the linear motor magnet 51 generates a changing magnetic field, and the attraction and repulsion between the magnetic poles of the linear motor magnet 51 and the linear motor 52 allow the linear motor extension seat 40 and the crossbeam 20 to move in the front-back direction relative to the base 10.

[0030] With the above structure, the present invention has a connecting part 122 on the transmission plate 12, and the first reference surface 23 is formed on the front side of the crossbeam 20 and the second reference surface 241 is formed on the top surface of the positioning block 24. This allows the present invention to directly install the screw drive device 30 on the base 10, or to install the screw drive device 30 with the wire extension seat 40. In this way, two different drive methods can be used on the same machine tool, achieving multiple uses in one machine, thereby reducing production costs and space usage, and improving ease of use.

[0031] In conclusion, this invention has excellent progressiveness and practicality compared to similar products. Furthermore, after reviewing technical data on this type of structure both domestically and internationally, no identical structure has been found in the literature. Therefore, this invention meets the requirements for a utility model patent, and an application is hereby filed in accordance with the law.

[0032] However, the above description is only one preferred embodiment of this invention. Therefore, any equivalent structural changes made by applying the specification and claims of this invention should be included within the scope of this invention.
