Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and more specifically, to a slide base assembly and a processing device. Background Art

[0002] The combination between the slide base and the crossbeam of the existing machine tool adopts a wall-mounted structure, and generally the slide base adopts a flat plate structure. However, the flat plate slide base is thin in thickness, and strong vibrations will occur during the actual processing, resulting in errors in the processed products and reducing the machining accuracy of the machining center.

[0003] Since the spindle box of the machine tool is directly installed on the slide base, the rigidity of the slide base has a direct impact on the machining accuracy and the machining surface quality of the machine tool. Moreover, since the slide base generally needs to be connected to the X-axis linear motor, which is the largest motor in the machine tool, the long-term operation of the linear motor generates heat, which will cause thermal expansion of the components and affect the machining accuracy of the machine tool and reduce the service life of the motor.

[0004] There is a slide base structure that can improve the accuracy retention and stability during the machining process of the machine tool. Although it can greatly enhance the stability during the machining process of the machine tool, there are weak stress points in this structure, which will affect the machining stability after long-term operation. In addition, the X-axis linear motor is directly installed in contact with the slide base, and the heat generated by the motor will also cause thermal deformation of the slide base, thereby affecting the machining accuracy. Summary of the Invention

[0005] The first object of the present invention is to provide a slide base assembly that can greatly strengthen the axial rigidity, eliminate the problem of casting deformation under long-term high suction, and at the same time extend the service life of the linear motor.

[0006] The second object of the present invention is to provide a processing device using the above slide base assembly.

[0007] To achieve the above first object, the present invention provides a slide base assembly, including a slide base main body and a thermal deformation-resistant plate; the slide base main body is made of a metal material; the thermal deformation-resistant plate is arranged on the negative Z-axis side of the slide base main body and is fixedly connected to the slide base main body; the thermal deformation-resistant plate is made of a mineral-based material, and an X-axis motor mover installation part is arranged on the side of the thermal deformation-resistant plate away from the slide base main body, and the X-axis motor mover installation part extends along the X-axis direction.

[0008] As can be seen from the above solution, by designing a slide base body made of metal material and a heat-resistant deformation plate made of mineral-based material, the X-axis motor mover mounting part is used to mount the mover of the linear motor. The mover is fixedly connected to the slide base body through the heat-resistant deformation plate. The heat-resistant deformation plate made of mineral-based material in the form of a transition plate can greatly strengthen the axial rigidity and eliminate the problem of casting deformation under long-term high suction. In addition, the transition plate made of mineral-based material can also ensure the distance between the X-axis motor mover and the X-axis motor stator for a long time, that is, keep the air gap unchanged, thereby increasing the service life of the motor.

[0009] A preferred solution is that the mineral-based material is granite, marble or mineral casting.

[0010] Thus, materials such as granite, marble and mineral casting have low thermal expansion coefficients, which makes them have small deformation when heated and have good heat-resistant deformation ability.

[0011] A preferred solution is that cooling channels are provided on the heat-resistant deformation plate, and the cooling channels are arranged close to the X-axis motor mover mounting part.

[0012] Thus, the setting of the cooling channels can achieve the cooling of the slide base. Since a large amount of heat is generated when the linear motor works, resulting in thermal deformation of the slide base, through the setting of the cooling channels, the heat generated by the linear motor during the operation of the machine tool can be greatly reduced, avoiding the problem of thermal expansion of components, prolonging the service life of the motor, and improving the stability of axial operation.

[0013] A further solution is that the cooling channels extend along the X-axis direction and are arranged opposite to the X-axis motor mover mounting part along the Z-axis direction.

[0014] Thus, by arranging the cooling channels opposite to the motor mover, the heat conduction path can be reduced and the cooling speed can be increased.

[0015] A preferred solution is that the slide base body includes a cylinder mounting part, a top strengthening part and a bottom strengthening part; both the cylinder mounting part and the top strengthening part are located above the bottom strengthening part and are arranged along the Y-axis direction; a cylinder mounting hole extending along the Z-axis direction is provided on the cylinder mounting part. The heat-resistant deformation plate is arranged on the bottom strengthening part, and the top strengthening part is arranged opposite to the X-axis motor mover mounting part in the Z-axis direction.

[0016] Thus, by providing a cylinder mounting hole inside the slide base, with the cylinder mounting part located above the cross beam, the gravity of the cylinder will directly act on the cross beam. Therefore, compared with the existing method of setting the cylinder on the side wall of the slide base, the load on the slide base can be reduced, the outward tilting pull of the cylinder on the slide base can be reduced, the deformation of the slide base can be alleviated, and the machining accuracy of the processing equipment can be improved.

[0017] A further solution is that a Z-axis linear motor mounting portion is provided on the side wall of the cylinder mounting portion away from the top strengthening portion.

[0018] It can be seen that the Z-axis linear motor mounting portion is used to mount the Z-axis linear motor.

[0019] A further solution is that the top strengthening portion includes a first strengthening side wall and a second strengthening side wall oppositely arranged along the X-axis direction, and at least one of the first strengthening side wall and the second strengthening side wall is provided with strengthening ribs extending along the Z-axis direction.

[0020] A further solution is that the top strengthening portion further includes a strengthening top wall, the top edges of the first strengthening side wall and the second strengthening side wall are both connected to the strengthening top wall, and the strengthening top wall is inclined downward from the side close to the cylinder mounting portion to the side away from the cylinder mounting portion; and / or the top strengthening portion further includes an internal strengthening plate, and the opposite two side edges of the internal strengthening plate are respectively connected to the first strengthening side wall and the second strengthening side wall.

[0021] It can be seen that the setting of the strengthening ribs and the inclined strengthening top wall can greatly improve the overall rigidity.

[0022] A further solution is that the cylinder mounting portion further includes a first extension wall, a second extension wall, a first arc-shaped connecting wall and a second arc-shaped connecting wall; the first extension wall extends outward along the positive X-axis direction from the first side wall of the cylinder mounting portion, and the second extension wall extends outward along the negative X-axis direction from the second side wall of the cylinder mounting portion; the first side edge of the first arc-shaped connecting wall is connected to the first extension wall, the second side edge of the first arc-shaped connecting wall is connected to the first strengthening side wall, and the first arc-shaped connecting wall bends away from the cylinder mounting portion; the first side edge of the second arc-shaped connecting wall is connected to the second extension wall, the second side edge of the second arc-shaped connecting wall is connected to the second strengthening side wall, and the second arc-shaped connecting wall bends away from the cylinder mounting portion.

[0023] A further solution is that at least one of the first arc-shaped connecting wall and the second arc-shaped connecting wall is provided with arc-shaped connecting rib strips extending along the circumferential direction of the corresponding arc-shaped connecting wall, the first end of the arc-shaped connecting rib strip is connected to the corresponding extension wall, and the second end of the arc-shaped connecting rib strip is connected to the corresponding strengthening side wall.

[0024] It can be seen that since the magnetic attraction directions of the X-axis linear motor and the Z-axis linear motor are perpendicular to each other at 90 degrees, the connection positions between the first extension wall and the first strengthening side wall, and between the second extension wall and the second strengthening side wall are the weak parts of the slide seat assembly structure. By designing the first arc-shaped connecting wall and the second arc-shaped connecting wall into arcs and adding arc-shaped connecting rib strips on their surfaces, the problem of structural weakness at the included angle connection position is eliminated, and at the same time, the installation contact surface of the counterweight cylinder fixing bracket is enlarged and widened, providing a more stable rigidity for the counterweight cylinder mounting hole.

[0025] Preferably, the bottom reinforcement part includes a top wall plate, a bottom wall plate, longitudinal reinforcement plates, and transverse reinforcement plates; the top reinforcement part is disposed on the positive Z-axis side of the top wall plate, the top wall plate and the bottom wall plate are disposed opposite to each other along the Z-axis direction, and both the longitudinal reinforcement plates and the transverse reinforcement plates are connected between the top wall plate and the bottom wall plate; the longitudinal reinforcement plates extend along the Y-axis direction, and the transverse reinforcement plates extend along the X-axis direction.

[0026] It can be seen that by providing the longitudinal reinforcement plates and the transverse reinforcement plates, the bottom reinforcement part can be designed as a hollow structure, and the longitudinal reinforcement plates and the transverse reinforcement plates can play a supporting role therein to ensure the overall rigidity of the bottom reinforcement part.

[0027] To achieve the above second object, the present invention provides a processing device, including a cross beam, an X-axis linear motor, and the above-mentioned slide assembly. The X-axis linear motor includes a motor stator and a motor mover. The motor stator is installed on the cross beam, and the motor mover is installed on the X-axis motor mover mounting part.

It should also be understood that terms defined in a general dictionary such as should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense unless specifically defined as such herein.

[0039] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0040] See Figure 1 , in this embodiment, the processing equipment is a machine tool, and the machine tool includes a bed 1, a crossbeam 2, a workbench 3, an X-axis linear motor 4, a slide assembly 5 and a spindle box 6.

[0041] The crossbeam 2 and the workbench 3 are both arranged on the bed 1. The slide assembly 5 is connected to the top of the crossbeam 2 through the X-axis linear motor 4. The spindle box 6 is installed on one side of the slide assembly 5 and is opposite to the workbench 3 in the Z-axis direction.

[0042] The X-axis linear motor 4 includes a motor stator 41 and a motor mover 42. The motor stator 41 is installed on the cross beam 2, and the motor mover 42 is installed on the X-axis motor mover installation part 522 of the carriage assembly 5.

[0043] See Figure 2 and Figure 3 , the carriage assembly 5 includes a carriage body 51 and a thermal deformation resistant plate 52. The carriage body 51 is made of a metal material. The thermal deformation resistant plate 52 is arranged on the negative Z-axis side of the carriage body 51 and is fixedly connected to the carriage body 51. The thermal deformation resistant plate 52 is made of a mineral-based material. An X-axis motor mover installation part 522 is arranged on the side of the thermal deformation resistant plate 52 away from the carriage body 51. The X-axis motor mover installation part 522 extends along the X-axis direction.

[0044] The mineral-based material is granite, marble or mineral casting. Materials such as granite, marble and mineral casting have a low coefficient of thermal expansion, which makes their deformation smaller when heated and have good thermal deformation resistance. Preferably, in this embodiment, the material of the carriage body 51 is HT350 casting material, and the material of the thermal deformation resistant plate 52 is granite.

[0045] Cooling channels 521 are formed on the thermal deformation resistant plate 52. The cooling channels 521 are arranged close to the X-axis motor mover installation part 522. The cooling channels 521 extend along the X-axis direction and are arranged opposite to the X-axis motor mover installation part 522 along the Z-axis direction. The arrangement of the cooling channels 521 can achieve the cooling of the carriage assembly 5. Since a large amount of heat is generated when the linear motor works, resulting in the thermal deformation of the carriage body 51, through the arrangement of the cooling channels 521, the heat generated by the linear motor during the operation of the machine tool can be greatly reduced, avoiding the problem of thermal expansion of components, prolonging the service life of the motor, and improving the stability of axial operation. By arranging the cooling channels 521 opposite to the motor mover 42, the heat conduction path can be reduced and the cooling speed can be increased. In this embodiment, the cooling channel is a through hole with a 1 / 8 pipe thread bottom diameter formed on the thermal deformation resistant plate 52. The cooling channels 521 can be externally connected to an oil cooling circulation circuit.

[0046] The carriage body 51 includes a cylinder installation part 511, a top strengthening part 512 and a bottom strengthening part 513. Both the cylinder installation part 511 and the top strengthening part 512 are located above the bottom strengthening part 513 and are arranged along the Y-axis direction. A cylinder installation hole 5111 extending along the Z-axis direction is formed on the cylinder installation part 511. The thermal deformation resistant plate 52 is arranged on the bottom strengthening part 513, and the top strengthening part 512 is arranged opposite to the X-axis motor mover installation part 522 in the Z-axis direction.

[0047] On the side wall of the cylinder mounting portion 511 away from the top strengthening portion 512, there is a Z-axis linear motor mounting portion 5112 for mounting a Z-axis linear motor (not shown).

[0048] See Figures 2 to 5 , the top strengthening portion 512 includes a first strengthening side wall 5121 and a second strengthening side wall 5122 oppositely arranged along the X-axis direction. At least one of the first strengthening side wall 5121 and the second strengthening side wall 5122 is provided with a strengthening rib 5123, and the strengthening rib 5123 extends along the Z-axis direction. The top strengthening portion 512 further includes a strengthening top wall 5124 and an internal strengthening plate 5125. The top edges of the first strengthening side wall 5121 and the second strengthening side wall 5122 are both connected to the strengthening top wall 5124, and the strengthening top wall 5124 is inclined downward from the side close to the cylinder mounting portion 511 to the side away from the cylinder mounting portion 511. The first strengthening side wall 5121 and the second strengthening side wall 5122 are arranged in parallel, and the internal strengthening plate 5125 is vertically connected between the first strengthening side wall 5121 and the second strengthening side wall 5122. The opposite two side edges of the internal strengthening plate 5125 are respectively connected to the first strengthening side wall 5121 and the second strengthening side wall 5122. The settings of the strengthening rib 5123, the internal strengthening plate 5125, and the inclined strengthening top wall 5124 can greatly improve the overall rigidity.

[0049] See Figure 5 , the cylinder mounting portion 511 includes a first extension wall 5113, a second extension wall 5114, a first arc-shaped connecting wall 5115, and a second arc-shaped connecting wall 5116. The first extension wall 5113 extends outward along the positive X-axis direction from the first side wall 501 of the cylinder mounting portion 511, the second extension wall 5114 extends outward along the negative X-axis direction from the second side wall 502 of the cylinder mounting portion 511. The first side edge of the first arc-shaped connecting wall 5115 is connected to the first extension wall 5113, the second side edge of the first arc-shaped connecting wall 5115 is connected to the first strengthening side wall 5121, and the first arc-shaped connecting wall 5115 bends away from the cylinder mounting portion 511. The first side edge of the second arc-shaped connecting wall 5116 is connected to the second extension wall 5114, the second side edge of the second arc-shaped connecting wall 5116 is connected to the second strengthening side wall 5122, and the second arc-shaped connecting wall 5116 bends away from the cylinder mounting portion 511.

[0050] At least one of the first arc-shaped connecting wall 5115 and the second arc-shaped connecting wall 5116 is provided with an arc-shaped connecting rib 5117, and the arc-shaped connecting rib 5117 extends along the circumferential direction of the corresponding arc-shaped connecting wall. The first end of the arc-shaped connecting rib 5117 is connected to the corresponding extension wall, and the second end of the arc-shaped connecting rib 5117 is connected to the corresponding strengthening side wall.

[0051] Since the attracting direction of the magnetic force of the X-axis linear motor 4 and the attracting direction of the magnetic force of the Z-axis linear motor are perpendicular to each other at 90 degrees, the connection positions of the first extension wall 5113 and the first reinforcing side wall 5121, and the connection positions of the second extension wall 5114 and the second reinforcing side wall 5122 are the weak parts of the structure of the slide assembly 5. By designing the first arc connecting wall 5115 and the second arc connecting wall 5116 into arcs, and adding arc connecting ribs 5117 on their surfaces, the problem of weak structure at the angle connection position is eliminated. At the same time, the installation contact surface 5118 of the cylinder fixing bracket is enlarged and widened, providing greater rigidity for the rigid counterweight cylinder installation hole 5111.

[0052] See Figure 3 and Figure 6 , the bottom reinforcing part 513 includes a top wall plate 5131, a bottom wall plate 5132, a longitudinal reinforcing plate 5133 and a transverse reinforcing plate 5134. The top reinforcing part 512 is arranged on the positive Z-axis side of the top wall plate 5131. The top wall plate 5131 and the bottom wall plate 5132 are arranged opposite to each other along the Z-axis direction. Both the longitudinal reinforcing plate 5133 and the transverse reinforcing plate 5134 are connected between the top wall plate 5131 and the bottom wall plate 5132. The longitudinal reinforcing plate 5133 extends along the Y-axis direction, and the transverse reinforcing plate 5134 extends along the X-axis direction.

[0053] By arranging the longitudinal reinforcing plate 5133 and the transverse reinforcing plate 5134, the bottom reinforcing part 513 can be designed as a hollow structure. The longitudinal reinforcing plate 5133 and the transverse reinforcing plate 5134 can play a supporting role therein, ensuring the overall rigidity of the bottom reinforcing part 513.

[0054] As can be seen from the above, by designing the slide body made of metal material and the heat-resistant deformation plate made of mineral-based material, the X-axis motor mover mounting part is used to mount the mover of the linear motor. The mover is fixedly connected to the slide body through the heat-resistant deformation plate. The heat-resistant deformation plate made of mineral-based material in the form of a transition plate can greatly strengthen the axial (i.e., Z-axis direction) rigidity and eliminate the concern about the deformation of the casting under long-term high attraction. In addition, the transition plate made of mineral-based material can also ensure the distance between the X-axis motor mover and the X-axis motor stator for a long time, that is, keep the air gap unchanged, thereby increasing the service life of the motor. In addition, the cylinder mounting part is located above the cross beam, and the gravity of the cylinder will directly act on the cross beam. Therefore, compared with the existing method of setting the cylinder on the side wall of the slide, it can reduce the load on the slide, reduce the outward tilting pulling force of the cylinder on the slide, reduce the deformation of the slide, and thus improve the machining accuracy of the processing equipment. In addition, as a counterweight component, the cylinder adjusts the air pressure to balance the weight distribution of the machine tool in real time, thereby improving the machining accuracy.

[0055] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
