Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a machine tool base and a processing center. Background Art

[0002] Currently, most lathes on the market utilize a vertical tool turret structure, either horizontal or vertical. All tools are mounted on the turret. If machining the inner hole of a workpiece requires machining, a boring tool is used. The boring bar is generally cylindrical and longer than the turning tool, with a larger cross-sectional area than the turning tool.

[0003] If a boring bar is installed on the turret, since the weight of the boring bar is greater than the weight of the turning tool and the length of the boring bar is longer than the length of the turning tool, on the one hand, the weight of the turret will increase, the speed of the turret rotation will slow down, affecting the speed of tool changing; on the other hand, the space occupied by the turret will increase, and other boring bars stored on the turret will easily interfere with the workpiece being processed.

[0004] Please see Figure 1 For example, patent publication CN110153712A discloses a dual-spindle, dual-turret compound machine tool that combines the functions of a lathe and a milling machine.

[0029] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0032] To provide a clearer and more accurate understanding of the present invention, the following detailed description is provided with reference to the accompanying drawings. The accompanying drawings illustrate exemplary embodiments of the present invention, with like reference numerals representing like elements. It should be understood that the scales shown in the accompanying drawings are not those of the actual implementation of the present invention. These scales are for illustrative purposes only and are not drawn to scale.

[0033] Please see Figure 2 and Figure 3 In a first aspect, the present invention provides a machine tool base, which includes a base body 110 and a tool magazine 120 disposed on the base body 110 .

[0034] It is understandable that the base body 110 is a casting, and thus the base body 110 is integrally formed by casting, which is beneficial to improving the production capacity of the base body 110 .

[0035] Please see Figure 3 The tool magazine 120 includes a fixed base 121, a connector 122, and a cutterhead 123. The fixed base 121 is used to mount and support the connector 122 and the cutterhead 123. The cutterhead 123 is rotatably connected to the fixed base 121 via the connector 122. The cutterhead 123 and the connector 122 are mounted on the base body 110 via the fixed base 121. Specifically, a cutterhead drive assembly is provided on the fixed base 121. The cutterhead drive assembly includes a motor mounted on the fixed base 121 and a roller cam mechanism disposed between the fixed base 121 and the connector 122. The motor drives the connector 122 and the cutterhead 123 to rotate relative to the fixed base 121 via the roller cam mechanism.

[0036] It is understood that the plane where the cutter head 123 is located can be set to be parallel to the plane where the base body 110 is located, or it can be set to be parallel to the front end surface of the base body 110. In the former case, the extension direction of the connecting member 122 is vertical, so that the tool magazine 120 is suitable for a vertical machining center; in the latter case, the extension direction of the connecting member 122 is horizontal (for example, perpendicular to the Figure 2 direction of the front end face of the center column 400), so that the tool magazine 120 is suitable for a horizontal machining center.

[0037] Please see Figure 3The periphery of the cutter disc 123 is provided with a tool mounting portion 1231, and the connecting member 122 is in the shape of an elongated strip to form an escape space p for accommodating a boring bar between the tool mounting portion 1231 and the fixing seat 121, and the length of the connecting member 122 is greater than the length of the accommodated boring bar. Since the boring bar occupies a long length, the length of the escape space p must also be long enough to accommodate the boring bar. In the embodiment of the present utility model, the connecting member 122 is configured as an elongated strip. "Elongated strip" means that the longitudinal length of the connecting member 122 is greater than the diameter of its cross section, or the longitudinal length of the connecting member 122 is greater than the longest diameter within the profile of its cross section. Figure 3 The tool mounting portion 1231 shown has a clamping portion for providing a clamping force applied to the boring bar in a radial direction, thereby firmly clamping the side surface of the boring bar.

[0038] It is understood that the length of the connecting member 122 can be set according to the length of the target boring bar on the tool mounting portion 1231, so that the target boring bar can be loaded on the tool mounting portion 1231. When a longer boring bar needs to be loaded, the connecting member 122 of longer length can be selected.

[0039] In an embodiment of the present invention, the fixed seat 121 of the tool magazine 120 is located on one side of the base body 110. Typically, the workpiece being machined corresponds to or is located near the center of the base body 110. Positioning the tool magazine 120, which carries the boring bar, on one side of the base body 110 allows it to avoid the workpiece being machined to a certain extent, thereby reducing interference with the workpiece. It should be noted that "located on one side of the base body" includes both the side located outside the base body and the side located inside the base body.

[0040] In the embodiment of the present invention, the placement of the boring bar is moved from the turret to the tool magazine, so that even if a boring bar with a longer length is loaded, it will not affect the rotation speed of the turret, thereby reducing the impact on the tool changing speed; and the fixing seat of the tool magazine loaded with the boring bar is set on one side of the base body 110, which can reduce interference with the workpiece being processed.

[0041] In some feasible embodiments, the connector 122 includes a connecting portion and a first telescopic portion connected to the connecting portion. One of the connecting portion and the first telescopic portion is connected to the fixed seat 121, and the other is connected to the cutter head 123. The connector 122 itself has a telescopic function, for example, the connector 122 is a pneumatic cylinder or an oil cylinder. Due to the telescopic function of the connector 122, the length of the connector 122 can be adjusted to accommodate boring bars of different lengths. Therefore, when loading a longer boring bar, the connector 122 only needs to be extended, without having to replace the connector 122.

[0042] Please see Figure 3In some feasible embodiments, in order to facilitate the installation of the tool magazine 120 on the base body 110 and to facilitate the adjustment of the position between the tool magazine 120 and the base body 110 when the tool magazine 120 is misaligned relative to the base body 110, the machine tool base also includes a bracket 130 and an adjustment mechanism 140. The fixed seat 121 is installed on the base body 110 through the bracket 130, and the adjustment mechanism 140 is arranged between the bracket 130 and the fixed seat 121. The adjustment mechanism 140 includes a fixing member 141 and an adjustment member 142 connected to the fixing member 141. The adjustment member 142 can adjust the position of the fixed seat 121 relative to the base body 110 along a preset straight line; one of the fixing member 141 and the adjustment member 142 is connected to the bracket 130, and the other of the fixing member 141 and the adjustment member 142 is connected to the fixed seat 121.

[0043] Specifically, if Figure 3 As shown, the fixing member 141 is fixed on the second fixing plate 132 of the bracket 130, and the fixing member 141 is a rectangular parallelepiped. A threaded hole is provided on the fixing member 141, and the extension direction of the threaded hole is the direction in which the tool magazine 120 is adjusted relative to the base body 110. The adjusting member 142 can be a bolt. By pressing the adjusting member 142 against the fixing seat 121 of the tool magazine 120, the position of the tool magazine 120 relative to the base body 110 can be adjusted. It can be understood that for each rotation of the bolt, the tool magazine 120 can move the length of one pitch relative to the base body 110 along the extension direction of the threaded hole. The size of the pitch can be adjusted according to actual conditions. For example, when the installation accuracy between the tool magazine 120 and the base body 110 is relatively large, the pitch can be smaller, for example, it can be 0.01 mm.

[0044] Since the tool magazine 120 is heavy after being loaded with boring bars, a greater thrust is required to adjust the tool magazine 120, and an adjustment mechanism 140 may not be able to provide the preset thrust. Figure 3 In some feasible embodiments, there are two adjustment mechanisms 140, both located on the same side of the fixing base 121. The bracket 130 includes a first fixing plate 131 connected to the base body 110 and a second fixing plate 132 connected to the fixing base 121. The bracket 130 also has a reinforcing rib 133 disposed between the first fixing plate 131 and the second fixing plate 132. The fixing base 121 and the second fixing plate 132 are locked together by fasteners. The fixing base 121 is provided with a waist-shaped hole that mates with the fastener, and the second fixing plate 132 is provided with a locking portion that mates with the fastener.

[0045] like Figure 3As shown, the two adjustment mechanisms 140 are spaced apart. During operation, the adjustment member 142 of one adjustment mechanism 140 is rotated one full circle, and then the adjustment member 142 of the other adjustment mechanism 140 is rotated one full circle. The tool magazine 120 is then measured to ensure it is in place. If not, the adjustment process is repeated. This prevents significant displacement of the tool magazine 120 relative to the base body 110, facilitating stable movement of the tool magazine 120, which stores boring bars, relative to the base body 110.

[0046] In order to ensure that the tool mounting portion 1231 on the tool disc 123 is exposed during tool change, and to protect the tool magazine 120 during non-tool change time to prevent cutting fluid and chips from entering the tool magazine 120, please refer to Figure 4 and Figure 6 In some feasible embodiments, the base further includes a base protective cover 150, a tool magazine protective cover 160 and a sliding door body 170 that cooperates with the tool magazine protective cover 160. The base protective cover 150 is arranged on the outer periphery of the base body 110, and the tool magazine protective cover 160 is connected to the base protective cover 150. The tool magazine protective cover 160 is supported on the base body 110 through the base protective cover 150. A tool changing port 161 exposing the tool mounting portion 1231 is provided on the tool magazine protective cover 160. The tool changing port 161 extends from the side of the tool magazine protective cover 160 close to the base body 110 to the top surface of the tool magazine protective cover 160. The sliding door body 170 can slide relative to the tool magazine protective cover 160 to cover the tool changing port 161 or expose the tool changing port 161. Specifically, as Figure 6 As shown, the base protection cover 150 is plate-shaped and extends outward from the side of the base body 110 , thereby providing support for the tool magazine protection cover 160 provided on the side of the base body 110 .

[0047] In some possible embodiments, see Figure 6 The machine tool base also includes a sliding support mechanism 180 and a guide mechanism 190. The sliding door body 170 is connected to the tool magazine protective cover 160 in a linear sliding manner through the sliding support mechanism 180 and the guide mechanism 190. The sliding support mechanism is arranged at the bottom of the tool magazine protective cover 160, and the guide mechanism is arranged at the top of the tool magazine protective cover 160. Specifically, the sliding support mechanism includes a guide block 181 and a slide rod 182, and the guide mechanism includes a guide plate 191 and a slide groove 192 that cooperates with the guide plate 191. The bottom of the tool magazine protective cover 160 is the main support part, so the bottom of the tool magazine protective cover 160 is provided with a guide block 181 and a slide rod 182; the top of the tool magazine protective cover 160 is the auxiliary support part, so the top of the tool magazine protective cover 160 is provided with a guide plate 191 and a slide groove 192, thereby minimizing the number of structural components of the sliding support mechanism and the guide mechanism between the tool magazine protective cover 160 and the base protective cover 150.

[0048] In order to facilitate the cooperation between the tool magazine 120 and the power turret 700, in some cases it is necessary to adjust the vertical height of the tool magazine 120 relative to the base body 110. Figure 3 In some feasible embodiments, the machine tool base further includes adjustment blocks 124, which are disposed on the tool magazine 120 to adjust the height of the tool magazine 120 by changing the number of adjustment blocks 124. It is readily understood that each adjustment block 124 is a standard component, and the height error of each adjustment block 124 is within an allowable error range. Therefore, when adjusting the height of the tool magazine 120 relative to the base body 110, the number of adjustment blocks 124 can be increased or decreased to raise or lower the height of the tool magazine 120. For example, the fixed base 121 includes a base plate 1211 and a socket 1212. The base plate 1211 is connected to the bracket 130. The connector 122 is rotatably disposed within the socket 1212, which is located above the base plate 1211. The adjustment blocks 124 are vertically disposed between the base plate 1211 and the socket 1212.

[0049] Some embodiments of the second aspect of the present invention further provide a machining center, which includes the base according to any one of the above embodiments.

[0050] The machining center also includes a spindle and a spindle motor that drives the spindle to rotate. The spindle is rotatably mounted on the front side of the base body. The height of a portion of the rear side of the base body is lower than that of the front side for mounting the spindle motor.

[0051] Please see Figure 2 and Figure 4 In order to improve the space utilization rate on the base body 110, in some feasible embodiments, the machining center further includes a spindle 200 and a spindle motor 300 for driving the spindle 200 to rotate. The spindle 200 is rotatably mounted on the front side 111 of the base body. The height of a portion of the rear side 112 of the base body is lower than that of the front side 111 of the base body for mounting the spindle motor 300. For details, please refer to Figure 2 as well as Figure 4 The above-mentioned partial area of the rear side 112 of the base body is provided with a relatively low mounting groove 113 .

[0052] It is understandable that the height of the top of the installation groove 113 is lower than the height of the top of other areas of the base body 110 , which can reduce the length of the transmission belt between the spindle motor 300 and the spindle 200 and facilitate the installation of the spindle motor 300 .

[0053] Please see Figure 2In order to ensure that the overall center of gravity of the structure installed on the base body 110 is roughly on the center line of the top surface of the base body 110, in some feasible embodiments, the spindle 200 is located on one side of the left and right directions of the base body 110, and the tool magazine 120 is installed on the other side of the base body 110 away from the spindle 200, so that the overall center of gravity of the machining center after the spindle 200 and the tool magazine 120 are installed can basically be maintained at a position corresponding to the middle area of the surface of the base body 110.

[0054] Please see Figure 2 and Figure 5 To reduce the power consumption of the vertical drive assembly during vertical movement of the crossbeam 500 and the power turret 700, the gravity of the crossbeam 500 and the power turret 700 is balanced, enabling the vertical drive assembly to drive the crossbeam 500 and the power turret 700 vertically relative to the column 400 at a faster acceleration. In some feasible embodiments, the machining center further comprises a column 400 and a crossbeam 500. The column 400 is fixedly mounted to the rear end 112 of the base body 110. The crossbeam 500 is slidably mounted on the front end of the column 400 in a direction perpendicular to the base body 110. A set of balancing cylinders 600 are disposed between the column 400 and the crossbeam 500. The set of balancing cylinders 600 are symmetrically arranged vertically. Each balancing cylinder 600 includes a fixed portion 610 and a second telescopic portion 620. One of the fixed portion 610 and the second telescopic portion 620 is connected to the column 400, and the other is connected to the crossbeam 500. Specifically, the fixing portion 610 is fixed to the middle region of the column 400 in the vertical direction, and the second telescopic portion 620 is located above the fixing portion 610 .

[0055] Please see Figure 2 and Figure 5 In order to save weight on the column 400 and facilitate the installation of a drive assembly that drives both the crossbeam 500 and the power turret 700 to move vertically, in some feasible embodiments, the machining center further comprises a motor, a screw, a nut, and a tailstock for driving the crossbeam 500 to move vertically. The front end of the column 400 is provided with a receiving slot 401 for accommodating the motor, screw, and tailstock. The nut is mounted on the crossbeam 500, the motor is mounted on one end of the column 400, and the tailstock is mounted on the other end of the column 400. The screw is located in the middle of the front end of the column 400 in the vertical direction. Two balancing cylinders 600 are located on either side of the screw, and two slide rails 800 enable the crossbeam 500 to slide relative to the column 400. The two slide rails 800 are located on either side of the two balancing cylinders 600. The above arrangement helps to improve the stability of the screw when driving the crossbeam 500 to move vertically relative to the column 400.

[0056] Please see Figure 2In some feasible embodiments, the machining center can be a vertical machining center. Specifically, the machining center can be a vertical machining lathe. The plane where the cutter head 123 is located is parallel to the plane where the base body 110 is located. The machining center also includes a power tool turret 700, which is slidably disposed on the front end surface of the beam 500 in a horizontal direction (e.g., perpendicular to the side wall of the column 400).

[0057] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.

[0058] The above examples are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
