Description

Technical Field

[0001] This invention relates to the field of horizontal machining center technology, and particularly to a horizontal machining center bed. Background Technology

[0002] The precision of a horizontal machining center is directly related to the structure of its bed. The precision of the bed structure directly determines the precision of the horizontal machining center, and good bed rigidity is key to ensuring that the precision of the horizontal machining center remains consistent over time. Existing horizontal machining centers suffer from insufficient bed rigidity due to unreasonable bed design; for example, an inadequate design of the coolant drainage channel directly results in low bed rigidity. Therefore, a new bed design is needed to improve the rigidity of horizontal machining center beds. Summary of the Invention

[0003] The purpose of this invention is to provide a horizontal machining center bed to solve the problem of low rigidity in existing horizontal machining center beds.

[0004] To solve the above-mentioned technical problems, the present invention provides a horizontal machining center bed, comprising: a Z-axis base arranged along the Z-axis; an X-axis base arranged along the X-axis, wherein the Z-axis end of the Z-axis base is connected to the middle of the X-axis base; a water tank receiving cavity is formed inside the Z-axis base; a Z-axis top plate is provided on the top of the Z-axis base, and a drain port communicating with the water tank receiving cavity is provided on the Z-axis top plate; a structural hole is provided on the X-axis base, and the structural hole allows the water tank to extend into the water tank receiving cavity of the Z-axis base.

[0005] Optionally, the Z-axis base includes two parallel Z-axis load-bearing plates arranged along the Z-axis, a Z-axis bottom plate connecting the bottom of the Z-axis load-bearing plates, a connecting plate connecting one side of the Z-axis load-bearing plates, and a Z-axis top plate connecting the top of the Z-axis load-bearing plates.

[0006] Optionally, the X-direction base includes an X-direction main support plate, an X-direction secondary support plate parallel to the X-direction main support plate, a first side plate connecting one end of the X-direction main support plate and the X-direction secondary support plate, a second side plate connecting the other end of the X-direction main support plate and the X-direction secondary support plate, and an upper plate and a lower plate connecting the X-direction main support plate and the X-direction secondary support plate, wherein the upper plate is disposed at the top of the X-direction main support plate and the X-direction secondary support plate, and the lower plate is disposed at the bottom of the X-direction main support plate and the X-direction secondary support plate.

[0007] Optionally, the Z-direction load-bearing plate, connecting plate, Z-direction bottom plate, and X-direction main load-bearing plate are all in contact with the ground, and the X-direction auxiliary load-bearing plate, first side plate, upper plate, lower plate, and second side plate form a cantilever structure disposed on the X-direction main load-bearing plate.

[0008] Optionally, the upper plate is higher than the height of the Z-direction top plate, and the X-direction main support plate is connected to the other side of the Z-direction load-bearing plate. The Z-direction base also includes a partition. The partition, the Z-direction top plate, the Z-direction bottom plate, and the X-direction main support plate form a water tank receiving cavity. The structural hole penetrates the X-direction main support plate and the lower plate.

[0009] Optionally, an end cover plate for sealing the Z-axis base is provided on the end face of the Z-axis base away from the X-axis base.

[0010] Optionally, a sealing groove is provided on the end face of the Z-axis base away from the X-axis base, and a sealing ring is provided in the sealing groove. The cover plate presses the sealing ring tightly onto the Z-axis base.

[0011] Optionally, it also includes a structural cover plate, and a mounting seat is provided on the top plate of the Z-axis base. The mounting seat is provided with mounting holes that can be connected to the structural cover plate or to the APC exchange workbench.

[0012] Optionally, the Z-axis base includes a first reinforcing rib disposed between the Z-axis load-bearing plate, the connecting plate, the Z-axis bottom plate, and the Z-axis top plate. The X-axis base includes a second reinforcing rib disposed between the X-axis main load-bearing plate, the X-axis secondary load-bearing plate, the first side plate, the upper plate, the lower plate, and the second side plate. Cooling channels are provided within the plate walls of the first reinforcing rib, the Z-axis load-bearing plate, the connecting plate, the Z-axis bottom plate, the Z-axis top plate, the X-axis main load-bearing plate, the X-axis secondary load-bearing plate, the first side plate, the upper plate, the lower plate, and the second side plate.

[0013] Optionally, a temperature sensor is also included, which is used to detect the temperature of the Z-axis base and the X-axis base.

[0014] The horizontal machining center bed provided by this invention has the following beneficial effects: Since the water tank cavity is located within the Z-axis base and the drain outlet is located on the Z-axis top plate, and a structural hole is provided on the X-axis base for the water tank to extend into the water tank cavity of the Z-axis base, the water tank is partially located within both the Z-axis and X-axis bases. Because the Z-axis end of the Z-axis base is connected to the middle of the X-axis base, the water tank can enter the water tank cavity along the Z-axis through the structural hole during installation. This positions the water tank cavity closer to the bottom of the horizontal machining center bed, preventing the water tank cavity from being located near the support structure. The guide rail structure is designed to reduce the rigidity of these structural components. Simultaneously, the water tank is positioned closer to the bottom of the horizontal machining center bed, allowing wastewater to flow directly into the tank. This ensures the heat from the cutting fluid flows directly into the tank, preventing the cutting fluid from flowing past the supporting guide rails and transferring heat to them, which could cause guide rail deformation and reduce the machining accuracy of the horizontal machining center. Furthermore, the drain outlet is located on the Z-axis top plate of the Z-axis base of the horizontal machining center bed, facilitating the collection and rapid discharge of wastewater and further reducing the impact of the cutting fluid's heat on the horizontal machining center bed.

Figure 6 This is a cross-sectional view of the Z-axis base and X-axis base of the horizontal machining center bed in an embodiment of the present invention. Figure 7 This is a top view of the Z-axis base, X-axis base, and water tank of the horizontal machining center bed in an embodiment of the present invention. Figure 8 This is a side view of the Z-axis base, X-axis base, and water tank of a horizontal machining center bed according to an embodiment of the present invention. This embodiment provides a horizontal machining center bed, including: a Z-axis base 100 arranged along the Z-axis; an X-axis base 200 arranged along the X-axis, with the Z-axis end of the Z-axis base 100 connected to the middle of the X-axis base 200; a water tank receiving cavity 110 formed inside the Z-axis base 100; a Z-axis top plate 120 provided on the top of the Z-axis base 100, with a drain port 121 communicating with the water tank receiving cavity 110 on the Z-axis top plate 120; and a structural hole 210 provided on the X-axis base 200, through which a water tank 300 extends into the water tank receiving cavity 110 of the Z-axis base 100.

[0024] Since the water tank cavity 110 is located within the Z-axis base 100, and the drain outlet 121 is located on the Z-axis top plate 120, and the X-axis base 200 has a structural hole 210 through which the water tank 300 extends into the water tank cavity 110 of the Z-axis base 100, the water tank 300 is partially located within both the Z-axis base 100 and the X-axis base 200. Because the Z-axis end of the Z-axis base 100 is connected to the middle of the X-axis base 200, the water tank 300 can enter the water tank cavity 110 along the Z-axis through the structural hole 210 during installation. Thus, the water tank cavity 110 is positioned closer to the bottom of the horizontal machining center bed. This design avoids placing the water tank cavity 110 close to the structural parts supporting the guide rails, thus preventing a reduction in the rigidity of these structural parts. Simultaneously, the water tank cavity 110 is positioned closer to the bottom of the horizontal machining center bed, allowing wastewater to flow directly into the water tank 300. This also allows the heat from the cutting fluid to flow directly into the water tank 300, preventing the cutting fluid from flowing past the structural parts supporting the guide rails and transferring heat to the guide rails, which could cause guide rail deformation and reduce the machining accuracy of the horizontal machining center. Furthermore, the drain outlet 121 is located on the Z-axis top plate 120 of the Z-axis base 100 of the horizontal machining center bed, facilitating the collection and rapid discharge of wastewater and further reducing the impact of the cutting fluid's heat on the horizontal machining center bed.

[0025] Specifically, the Z-axis base 100 includes two parallel Z-axis load-bearing plates 130 arranged along the Z-axis, a Z-axis bottom plate 150 connecting the bottom of the Z-axis load-bearing plates 130, and a connecting plate 140 connecting one side of the Z-axis load-bearing plates 130. A Z-axis top plate 120 connects to the top of the Z-axis load-bearing plates 130. The X-axis base 200 includes an X-axis main load-bearing plate 220, an X-axis secondary load-bearing plate 230 parallel to the X-axis main load-bearing plate 220, a first side plate 240 connecting one end of the X-axis main load-bearing plate 220 and the X-axis secondary load-bearing plate 230, a second side plate 270 connecting the other end of the X-axis main load-bearing plate 220 and the X-axis secondary load-bearing plate 230, and an upper plate 250 and a lower plate 260 connecting the X-axis main load-bearing plate 220 and the X-axis secondary load-bearing plate 230. The upper plate 250 is disposed on the X-axis main load-bearing plate 220 and the X-axis secondary load-bearing plate 230. The top of the plate 230, the bottom plate 260 is disposed at the bottom of the X-direction main support plate 220 and the X-direction auxiliary support plate 230; wherein, the Z-direction load-bearing plate 130, the connecting plate 140, the Z-direction bottom plate 150 and the X-direction main support plate 220 are all in contact with the ground, the X-direction auxiliary support plate 230, the first side plate 240, the upper plate 250, the lower plate 260 and the second side plate 270 form a cantilever structure disposed on the X-direction main support plate 220, the upper plate 250 is higher than the height of the Z-direction top plate 120, and the X-direction main support plate 220 is connected to the other side of the Z-direction load-bearing plate 130, the Z-direction base 100 also includes a partition, the partition, the Z-direction top plate 120, the Z-direction bottom plate 150 and the X-direction main support plate 220 form a water tank receiving cavity 110, and the structural hole 210 penetrates the X-direction main support plate 220 and the bottom plate 260. Since the structural hole 210 penetrates the X-direction main support plate 220 and the lower plate 260, it not only meets the functional requirements of water tank 300 entering and exiting, but also ensures that the opening will not significantly weaken the strength of this key load-bearing component through the support of the main support plate.

[0026] Preferably, the Z-direction load-bearing plate 130, the connecting plate 140, the Z-direction bottom plate 150, the Z-direction top plate 120, the X-direction main support plate 220, the X-direction auxiliary support plate 230, the first side plate 240, the upper plate 250, the lower plate 260, and the second side plate 270 are provided with weight-reducing holes. This can reduce weight and avoid stress concentration during the casting of the bed, thereby improving the machinability of the bed.

[0027] Preferably, the upper plate 250 and the lower plate 260 are inclined relative to the horizontal plane. This creates two support surfaces of different heights at the intersection of the upper plate 250 and the X-direction main support plate 220, and at the intersection of the upper plate 250 and the X-direction auxiliary support plate 230. Support rails are then installed on these two support surfaces to form two high and low support rails along the X-direction. This suppresses the influence of the cutting force of the cutting head mounted on the two high and low support rails on the horizontal machining center during cutting. Furthermore, since the X-direction auxiliary support plate 230, the first side plate 240, the upper plate 250, the lower plate 260, and the second side plate 270 form a cantilever structure mounted on the X-direction main support plate 220, and the upper plate 250 is provided with two X-direction high and low support rails, the static stiffness of the horizontal machining center bed is improved.

[0028] Preferably, the horizontal machining center bed further includes a water tank 300, which includes a first part disposed within the Z-axis base 100 and the X-axis base 200, and a second part disposed outside the Z-axis base 100 and the X-axis base 200. This optimizes the layout of the horizontal machining center, allowing the water tank 300 to occupy less area and reducing the overall volume of the horizontal machining center.

[0029] Preferably, the horizontal machining center bed also includes three base feet 400, which are arranged in a triangle. Utilizing the principle that three points determine a surface, the entire base is covered to the maximum extent, making the installation and relocation of the horizontal machining center bed more convenient, and minimizing the impact of ground undulations on the accuracy of the horizontal machining center bed.

[0030] Furthermore, one of the foot 400 is installed at the middle of the end of the Z-axis base 100 away from the X-axis base 200 and located below the connecting plate 140. The other two foot 400 are installed on both sides of the Z-axis base 100 near the X-axis base 200 and located below the X-axis main bearing plate 220. This makes the support of the horizontal machining center bed more stable and minimizes the impact of ground undulations on the accuracy of the horizontal machining center bed.

[0031] Preferably, an end cover plate 500 for sealing the Z-axis base 100 is provided on the end face of the Z-axis base 100 away from the X-axis base 200.

[0032] Preferably, a sealing groove is provided on the end face of the Z-axis base 100 away from the X-axis base 200, a sealing ring is provided in the sealing groove, and the cover plate presses the sealing ring tightly onto the Z-axis base 100.

[0033] Preferably, the horizontal machining center bed further includes a structural cover plate, and a mounting base 122 is provided on the top plate of the Z-axis base 100. The mounting base 122 is provided with mounting holes that can be connected to the structural cover plate or to the APC (Automatic Pallet Exchanger) exchange table. Thus, when the horizontal machining center does not have an APC exchange table, the APC exchange table is not installed, and the mounting structural cover plate on the base seals the mounting holes, allowing the horizontal machining center bed to be standardized.

[0034] Preferably, the Z-axis base 100 includes a first reinforcing rib, which is disposed between the Z-axis load-bearing plate 130, the connecting plate 140, the Z-axis bottom plate 150, and the Z-axis top plate 120. The X-axis base 200 includes a second reinforcing rib, which is disposed between the X-axis main support plate 220, the X-axis secondary support plate 230, the first side plate 240, the upper plate 250, the lower plate 260, and the second side plate 270. The first reinforcing rib and the Z-axis... Cooling channels are provided in the walls of the load-bearing plate 130, the connecting plate 140, the Z-direction bottom plate 150, the Z-direction top plate 120, the X-direction main support plate 220, the X-direction auxiliary support plate 230, the first side plate 240, the upper plate 250, the lower plate 260, and the second side plate 270. By providing cooling water to the cooling channels, the temperature of the Z-direction base 100 and the X-direction base 200 can be controlled, avoiding excessive local temperature of the Z-direction base 100 and the X-direction base 200, which could lead to deformation of the bed.

[0035] Preferably, the horizontal machining center bed also includes a temperature sensor for detecting the temperature of the Z-axis base 100 and the X-axis base 200. This allows for real-time monitoring of the bed temperature, adjustment of cutting parameters, and ensuring the overall accuracy of the bed.

[0036] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
