Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and in particular to a sliding saddle device. Background Technology

[0002] The saddle in a machining center is a key component of the machine tool, primarily used to support the worktable and enable its precise movement. Different types and structures of saddle designs directly affect the performance and accuracy of the equipment.

[0003] Saddles are typically mounted on the machine tool bed or crossbeam and slide vertically or horizontally via guide rails. For example, in a horizontal machining center, the saddle moves up and down along a vertical guide rail, while in a gantry machining center, the saddle moves along a crossbeam via a sliding guide rail. Some designs employ threaded drive rods or saddle structures to enhance stability and limit the sliding range with reinforcing plates.

[0004] When the existing slide saddle is subjected to force in the spindle box, the slider on it will move slightly due to the gap between it and the slide rail, affecting the accuracy. How to compensate for the gap between the slider and the slide rail in real time and stabilize the slider position has become an industry problem. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, the present invention provides a sliding saddle device that ensures the stability of the sliding saddle body.

[0006] The technical solution adopted in this invention is:

[0007] A sliding saddle device is disclosed for mounting the spindle box of a machine tool on the column of the machine tool. The sliding saddle device includes a saddle body, a traversing system, and a lifting system. The column is provided with a traversing slide rail, and the saddle body is provided with a traversing-adaptive slider system that slides along the traversing slide rail. The saddle body is also provided with a lifting slide rail, and the saddle body is mounted on the traversing slide rail of the column via the traversing-adaptive slider system. The spindle box is slidably and liftably mounted on the lifting slide rail of the saddle body. The traversing-adaptive slider system includes a traversing sliding base and a traversing slider control system. The device comprises a transverse displacement generator and a transverse displacement position control device. The transverse displacement sliding base slides horizontally along the transverse displacement slide rail. The transverse displacement generator is drivenly connected to the transverse displacement slide rail and electrically connected to the transverse displacement position control device. The transverse displacement sliding base is provided with a transverse displacement inclined surface. The angle between the transverse displacement inclined surface and the transverse displacement slide rail is 2 to 3.5 degrees. The transverse displacement slider control device is slidably mounted on the transverse displacement inclined surface of the transverse displacement sliding base. The transverse displacement position control device is mounted on the transverse displacement sliding base and is drivenly connected to the transverse displacement slider control device.

[0008] Preferably, the traverse system includes a traverse motor and a traverse lead screw. The traverse motor is mounted on the column, and the traverse lead screw is mounted on the output end of the traverse motor. The traverse lead screw is connected to the slide saddle body for transmission.

[0009] Preferably, the lifting system includes a lifting motor and a lifting screw. The lifting motor is mounted on the slide saddle body, and the lifting screw is mounted on the output end of the lifting motor. The lifting screw is connected to the main spindle box for transmission.

[0010] Preferably, the lifting adaptive slider system includes a lifting sliding base, a lifting slider control device, a lifting power generation device, and a lifting position control device.

[0011] Preferably, the transverse sliding base slides along the surface of the transverse sliding rail.

[0012] Preferably, the lateral sliding block control device includes two lateral position control sliders, which are adapted to corresponding lateral sliding ramps. The two lateral position control sliders are installed via a crossbeam. The crossbeam has a long groove perpendicular to the direction of the lateral sliding rail. The lateral position control slider is provided with a traction pin that slides with the long groove. The long groove avoids the lateral sliding block when it slides along the lateral sliding ramp and causes a lateral movement perpendicular to the direction of the lateral sliding rail. The lateral position control device is connected to one of the crossbeams in a transmission connection.

[0013] Preferably, the transverse power generation device includes a transverse generator, and a transverse rack is provided on the transverse slide rail, wherein the transverse generator is connected to the transverse rack in a transmission connection.

The transverse adaptive slider system slides along the transverse slide rail, thereby realizing the transverse movement of the saddle body. The saddle body is equipped with a lifting slide rail, and the saddle body is installed on the transverse slide rail of the column through the transverse adaptive slider system. The spindle box is slidably and vertically installed on the lifting slide rail of the saddle body, realizing the lifting of the spindle box.

The lateral sliding base has a lateral inclined surface with an angle of 2 to 3.5 degrees between it and the lateral slide rail. The lateral slider control device is slidably mounted on the lateral inclined surface of the lateral sliding base. During the sliding process of the lateral slider control device along the lateral inclined surface, it changes its position relative to the lateral slide rail in a direction perpendicular to the direction of the lateral slide rail. The saddle body is mounted on the lateral slider control device, which in turn changes the position of the saddle body in a direction perpendicular to the direction of the lateral slide rail, thus ensuring the precise positioning of the saddle body. The lateral position control device is mounted on the lateral sliding base and driven and connected to the lateral slider control device, ensuring the stability of the saddle body's posture.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figure 1 — Figure 6 As shown, this embodiment provides a sliding saddle device for mounting the spindle box of a machine tool on a column. The column is the machine tool's column. The sliding saddle device includes a sliding saddle body 1, a transverse system, and a lifting system. A transverse slide rail 2 is provided on the column. A transverse adaptive slider system 3 is provided on the sliding saddle body 1. The transverse adaptive slider system 3 slides along the transverse slide rail 2, thereby realizing the transverse movement of the sliding saddle body 1. A lifting slide rail 11 is provided on the sliding saddle body 1. The sliding saddle body 1 is mounted on the transverse slide rail 2 of the column through the transverse adaptive slider system 3. The spindle box is slidably and vertically mounted on the lifting slide rail 11 of the sliding saddle body 1, realizing the lifting and lowering of the spindle box.

[0030] Specifically, the lateral adaptive slider system 3 includes a lateral sliding base 31, a lateral slider control device 32, a lateral power generation device 33, and a lateral position control device 34. The lateral sliding base 31 slides horizontally along the lateral slide rail 2. The lateral power generation device 33 is connected to the lateral slide rail 2 via a transmission connection and is electrically connected to the lateral position control device 34. The lateral sliding base 31 is provided with a lateral inclined surface 311, and the angle between the lateral inclined surface 311 and the lateral slide rail 2 is 2 to 3.5 degrees. The lateral slider control device 32 is slidably mounted on the lateral inclined surface 311 of the lateral sliding base 31. On the 1st, during the sliding of the transverse slider control device 32 along the transverse inclined plane 311, the transverse slider control device 32 changes its position relative to the transverse slide rail 2 in the direction perpendicular to the direction of the transverse slide rail 2. The slide saddle body 1 is installed on the transverse slider control device 32, which can then change the position of the slide saddle body 1 in the direction perpendicular to the direction of the transverse slide rail 2, so that the position of the slide saddle body 1 is accurate. The transverse position control device 34 is installed on the transverse sliding base 31. The transverse position control device 34 is connected to the transverse slider control device 32 through transmission, which ensures the stability of the posture of the slide saddle body 1.

[0031] Specifically, the lateral movement system includes a lateral movement motor and a lateral movement screw. The lateral movement motor is mounted on the column, and the lateral movement screw is mounted on the output end of the lateral movement motor. The lateral movement screw is connected to the slide saddle body 1 for transmission. The slide saddle body 1 has a lateral movement seat 12 for the lateral movement screw to pass through. The lateral movement seat 12 is used to install a lateral movement nut that is compatible with the lateral movement screw. The lateral movement of the slide saddle body 1 is realized through the threaded engagement between the lateral movement screw and the lateral movement nut.

[0032] Specifically, the lifting system includes a lifting motor and a lifting screw. The lifting motor is installed on the slide saddle body 1, and the lifting screw is installed on the output end of the lifting motor. The lifting screw is connected to the spindle box for transmission. The slide saddle body 1 has a pre-set lifting motion seat 13 for the lifting screw to pass through. The lifting motion seat 13 is used to install a lifting nut that is compatible with the lifting screw. The lifting of the spindle box is realized through the threaded engagement between the lifting screw and the lifting nut.

[0033] Specifically, the machine tool's spindle box moves along the lifting adaptive slider system. Figure 1 The lifting slide rail 11 on the slide saddle body 1 shown slides up and down. The main shaft box is equipped with a lifting adaptive slider system adapted to the lifting slide rail 11. Similar to the transverse adaptive slider system 3, the lifting adaptive slider system includes a lifting sliding base, a lifting slider control device, a lifting power generation device, and a lifting position control device. The lifting sliding base slides up and down along the lifting slide rail 11. The lifting power generation device is drivenly connected to the lifting slide rail 11 and electrically connected to the lifting position control device. The lifting sliding base is equipped with a lifting inclined surface, and the angle between the lifting inclined surface and the lifting slide rail 11 is 2 degrees to 3.5 degrees. The lifting slider control device is slidably mounted on the lifting inclined surface of the lifting sliding base. During the sliding process of the lifting slider control device along the lifting inclined surface, the lifting slider control device changes its position relative to the lifting slide rail 11 in the direction perpendicular to the direction of the lifting slide rail 11. The spindle box is mounted on the lifting slider control device, which can then change the position of the spindle box in the direction perpendicular to the direction of the lifting slide rail 11, so that the position of the spindle box is accurate. The lifting position control device is mounted on the lifting sliding base and is connected to the lifting slider control device through a transmission, which ensures the stability of the spindle box's posture.

[0034] Specifically, the transverse sliding base 31 slides along the surface of the transverse sliding rail 2. Since there is an unavoidable gap between each transverse sliding base 31 and the transverse sliding rail 2, the transverse slider control device 32 is installed on the saddle body 1. By changing the position of the transverse slider control device 32 in the direction perpendicular to the direction of the transverse sliding rail 2, the position of the saddle body 1 in the direction perpendicular to the direction of the transverse sliding rail 2 can be controlled, thereby maintaining stability when the saddle body 1 slides.

[0035] Specifically, the transverse slider control device 32 includes two transverse position control sliders 321, which are adapted to corresponding transverse inclined surfaces 311. The two transverse position control sliders 321 are installed via a crossbeam 322, which has a long groove perpendicular to the direction of the transverse slide rail 2. The transverse position control slider 321 has a traction pin that slides in the long groove. The long groove avoids the transverse position control slider 321 when it slides along the transverse inclined surface 311 and causes a transverse movement perpendicular to the direction of the transverse slide rail 2. The transverse position control device 34 is connected to one of the crossbeams 322. By adjusting the position of the transverse position control slider 321 on the transverse inclined surface 311, the position of the transverse sliding base 31 on the transverse slide rail 2 perpendicular to the direction of the transverse slide rail 2 can be changed, thereby controlling the sliding accuracy.

[0036] Specifically, the transverse shifting generator 33 includes a transverse shifting generator, a transverse shifting rack 21 is provided on the transverse shifting slide rail 2, the output end of the transverse shifting generator meshes with the transverse shifting rack 21 to achieve a transmission connection, the transverse shifting generator is electrically connected to the storage battery, the transverse shifting generator is used to charge the storage battery, and the transverse shifting position control device 34 is electrically connected to the storage battery to achieve power supply.

[0037] It is worth noting that the transverse position control device 34 and the lifting position control device also play an important role in the spindle box position adjustment, and are used to fine-tune the spindle box position before the equipment is run.

[0038] Specifically, the transverse position control device 34 includes a transverse control motor 341 and a transverse control lead screw 343. The transverse control lead screw 343 is mounted on the output end of the transverse control motor 341 via a universal joint to avoid interference. The crossbeam 322 of the transverse slider control device 32 is provided with a transverse control joint bearing. The transverse control lead screw 343 and the transverse control joint bearing of the transverse slider control device 32 are connected by a threaded pair to realize the position control of the transverse position control slider 321.
