The embodiment of the application provides a machining center (also called as a numerical control machine tool) which can improve the machining efficiency of the machining center. Specifically, the machining center may perform cutting operations including, but not limited to, milling, drilling, boring, tapping, and the like. The processing center will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a machining center according to an embodiment of the application. The machining center 10 includes a machine body 100, and the machine body 100 may include a base 110 and a housing (not shown). It will be appreciated that the base 110 is adapted to support and carry the processing equipment, mechanisms, and control systems of the processing center 10. The housing is used to form the exterior profile of the machining center 10 to enclose the machining equipment, mechanisms, and portions of the control system of the machining center 10 within the housing.

Referring to fig. 2 and fig. 3 in combination, fig. 2 is a first schematic diagram of a processing center in a communication state of an isolation door according to an embodiment of the application, and fig. 3 is a first schematic diagram of the processing center in a separation state of the isolation door according to an embodiment of the application. Machining center 10 includes tool changing mechanism 300, spindle mechanism 200, and tool setting gauge 400. The machine body 100 includes a processing space 100a and a non-processing space 100b provided at one side of the processing space 100 a. The spindle mechanism 200 is movably mounted to the machine body 100 such that the spindle mechanism 200 is movable between the machining space 100a and the non-machining space 100b. The tool changing mechanism 300 is disposed in the non-processing space 100b, and the tool changing mechanism 300 is fixedly mounted on the machine body 100, and the tool changing mechanism 300 is used for changing the tool of the spindle mechanism 200. Tool setting gauge 400 is disposed in non-machining space 100b, and tool setting gauge 400 is fixed to machine body 100, tool setting gauge 400 being used to detect a tool when spindle mechanism 200 changes tools.

The spindle mechanism 200 is a main actuator of the machining center 10, and the spindle mechanism 200 includes a headstock 210 and a spindle 220 disposed in the headstock 210. The spindle mechanism 200 is used for carrying (supporting) a tool, and for transmitting power to the tool to effect cutting of a workpiece. A broaching device may be disposed in the spindle mechanism 200, and the tool may be detachably connected to the broaching device through a tool shank, thereby enabling the tool to be connected to the spindle mechanism 200. The tool changing mechanism 300 is a matching mechanism of the spindle mechanism 200, and the tool changing mechanism 300 is used for storing tools of various different types and specifications and executing tool changing operation on the spindle mechanism 200 so as to realize automatic tool changing without manual tool changing, thereby improving efficiency.

In the embodiment of the application, by arranging the tool changing mechanism 300 in the non-processing space 100b, when the spindle mechanism 200 needs to change tools, the spindle mechanism 200 can be controlled to move from the processing space 100a to the non-processing space 100b, so that the tool changing mechanism 300 can change tools of the spindle mechanism 200. For example, when the spindle mechanism 200 finishes machining a certain portion on the workpiece, it is possible to move from the current machining position to the non-machining space 100b for tool changing without returning to the origin (or tool changing point).

The machining space 100a refers to a space region of the machining center 10 for performing a machining operation on a workpiece, and a table 150 may be disposed in the machining space 100a to clamp the workpiece. The non-machining space 100b is a space region where the machining center 10 does not perform machining work, and a plurality of non-machining spaces 100b may be provided, and the tool changing mechanism 300 may be provided in one of them. It should be noted that the spindle mechanism 200 may be moved to the non-processing space 100b, and the spindle mechanism 200 may be located entirely in the non-processing space 100b, or the spindle mechanism 200 may be located partially in the non-processing space 100b, which is not limited in the embodiment of the present application.

Thus, in the embodiment of the present application, by fixedly arranging the tool changing mechanism 300 in the non-processing space 100b, when the spindle mechanism 200 needs to change tools, only the spindle mechanism 200 needs to be controlled to move to the non-processing space 100b, and the tool changing mechanism 300 only performs tool changing operation, and just because the tool changing mechanism 300 is fixed (the position is not moved here), the alignment detection process of the tool changing mechanism 300 is omitted, so that the tool changing time is reduced, the tool changing efficiency is improved, and the processing efficiency of the processing center 10 is further improved. In addition, by fixedly mounting the tool changing mechanism 300 to the machine body 100, automatic tool changing is realized by controlling the spindle mechanism 200 to move to the non-processing space 100b to cooperate with the tool changing mechanism 300, and a moving mechanism is not required to be arranged for the tool changing mechanism 300, i.e. a set of moving mechanism is omitted, so that the production cost of the processing center 10 can be reduced. And just because the moving mechanism is not required to be arranged on the tool changing mechanism 300, the control process of the tool changing mechanism 300 is simple, the running stability of the tool changing mechanism 300 can be improved, the failure rate can be reduced, and the maintenance cost of the tool changing mechanism 300 can be reduced.

Tool setting gauge 400 is used to detect a dimensional parameter (e.g., diameter or length) of a tool to confirm whether the tool replaced by spindle mechanism 200 is a tool required for the next machining process of a workpiece, and to detect whether there is a loss or damage to the tool replaced by spindle mechanism 200. The tool setting gauge 400 may be various, for example, the tool setting gauge 400 may be a laser tool setting gauge, a contact tool setting gauge, or a plug-in tool setting gauge, which is taken as an example in the drawings of the present application, and the present application is not to be considered as being limited by the present application.

Specifically, when the tool setting gauge 400 detects that the tool replaced by the spindle mechanism 200 has loss (such as edge wear), the detected dimensional parameter of the tool may be fed back to the control system of the machining center 10, so that the control system generates a corresponding compensation value according to the loss condition of the tool, and adjusts the machining parameter of the workpiece according to the compensation value, so that the machining precision of the workpiece can be ensured under the condition of the loss of the tool. When tool setting gauge 400 detects a damage to the tool being replaced (e.g., a broken edge portion), it may feed back to the control system of machining center 10 and alert to the replacement of a new tool.

It will be appreciated that in some embodiments, tool setting gauge 400 may also detect a previously carried tool on spindle mechanism 200 prior to tool change by spindle mechanism 200, and may detect if the tool has been damaged during a previous use.

According to the embodiment of the application, by arranging tool setting gauge 400 in non-processing space 100b, tool setting gauge 400 is far away from spindle mechanism 200 in the process of processing a workpiece in processing space 100a by spindle mechanism 200, so that chips generated in the process of processing the workpiece and cooling liquid used in the process of processing can be reduced to splash onto tool setting gauge 400, damage or pollution to tool setting gauge 400 can be avoided, influence on tool setting gauge 400 can be reduced, and thus the detection precision and accuracy of tool setting gauge 400 on a tool can be improved.

In addition, in the embodiment of the present application, both the tool changing mechanism 300 and the tool setting gauge 400 are disposed in the non-processing space 100b, after the spindle mechanism 200 finishes tool changing in the non-processing space 100b, the tool setting gauge 400 can immediately detect the changed tool, and if the tool setting gauge 400 detects that there is an abnormality in the changed tool, another tool can be directly replaced in the non-processing space 100b, and compared with the tool setting gauge 400 disposed in the processing space 100a, the spindle mechanism 200 is prevented from moving back and forth between the processing space 100a and the non-processing space 100b due to the abnormality in the tool, the movement stroke of the spindle mechanism 200 can be reduced, and the time consumed by the spindle mechanism 200 to move back and forth can be reduced, thereby reducing the tool changing time and further improving the processing efficiency of the processing center 10.

Referring to fig. 2 and fig. 4 in combination, fig. 4 is a second schematic diagram of a machining center in a separated state of an isolation door according to an embodiment of the application. The machining center 10 further includes an isolation door 500, and the isolation door 500 is movably disposed in the machine body 100 to communicate or isolate the machining space 100a and the non-machining space 100b.

It can be appreciated that the isolation gate 500 has two states: a blocking state in which the isolation door 500 blocks the processing space 100a from the non-processing space 100 b; and a communication state in which the isolation door 500 communicates the processing space 100a with the non-processing space 100b. The isolation door 500 is movably disposed in the machine body 100, so that the isolation door 500 can be moved and switched between two states. Specifically, when the spindle mechanism 200 performs a machining operation on a workpiece in the machining space 100a, the isolation door 500 may be in an isolated state; the isolation door 500 may be moved to be switched to the communication state at the time of the tool changing operation of the spindle mechanism 200.

In this embodiment, the isolation door 500 is movably disposed in the machine body 100, and in the process of processing the workpiece in the processing space 100a by the spindle mechanism 200, the processing space 100a and the non-processing space 100b are isolated by controlling the isolation door 500, so that the isolation door 500 plays an isolating role, and can thoroughly prevent chips generated in the processing process of the workpiece and cooling liquid used in the processing process from splashing onto the tool setting gauge 400, so as to prevent the tool setting gauge 400 from being damaged or polluted, improve the detection precision and accuracy of the tool carried by the spindle mechanism 200 by the tool setting gauge 400, and further prolong the service life of the tool setting gauge 400.

In addition, since the tool changing mechanism 300 is fixedly disposed in the non-processing space 100b, when the spindle mechanism 200 processes a workpiece in the processing space 100a by providing the movable isolation door 500 in the machine body 100, the non-processing space 100b is isolated from the processing space 100a by controlling the isolation door 500, and chips generated during processing of the workpiece and cooling liquid used during processing can be prevented from splashing onto the tool changing mechanism 300, damage or pollution to the tool changing mechanism 300 is avoided, the service life of the tool changing mechanism 300 is prolonged, and the maintenance cost of the tool changing mechanism 300 is further reduced.

Alternatively, referring to fig. 3, tool setting gauge 400 is disposed between tool changing mechanism 300 and isolation door 500.

Tool setting gauge 400 is disposed between tool changing mechanism 300 and isolation door 500, then tool setting gauge 400 is located on the return path of spindle mechanism 200, after spindle mechanism 200 changes the tool at tool changing mechanism 300, the changed tool can be directly detected by tool setting gauge 400 in the travel path of returning to machining space 100a, the travel path of spindle mechanism 200 is not additionally increased, and the travel path of spindle mechanism 200 can be reduced compared with the travel path of spindle mechanism 400 disposed at other positions, the total time of the tool changing process can be reduced, and thus the machining efficiency of machining center 10 on the workpiece can be improved.

Similarly, when tool setting gauge 400 is disposed between tool changing mechanism 300 and isolation door 500, tool setting gauge 400 is located on the travel path of spindle mechanism 200, when spindle mechanism 200 has a detection requirement for the original tools carried by the tool setting gauge, the original tools on spindle mechanism 200 can be detected by tool setting gauge 400 before the spindle mechanism moves to tool changing mechanism 300 (i.e. before tool changing), i.e. the detection process occurs on the travel path of spindle mechanism 200, the travel path of spindle mechanism 200 is not additionally increased, and compared with the case that tool setting gauge 400 is disposed at other positions, the travel path of spindle mechanism 200 is also reduced, the total time of the tool changing process is reduced, and thus the processing efficiency of machining center 10 on workpieces is improved.

Referring to fig. 4 and 5 in combination, fig. 5 is a first cross-sectional view of a machining center according to an embodiment of the application. The base 110 includes a bearing surface 111, where the bearing surface 111 includes a first area 1111 and a second area 1112, the first area 1111 is opposite to the non-processing space 100b, and the first area 1111 is convexly provided with a first boss 112. The machine body 100 further includes a gantry 120, where the gantry 120 is fixedly mounted to the second region 1112, and the spindle mechanism 200 is movably mounted to the gantry 120.

It is understood that the carrying surface 111 further includes a third area 1113, the third area 1113 is opposite to the processing space 100a, and the table 150 may be disposed in the third area 1113.

The second region 1112 may be disposed at one side of the first region 1111 and the third region 1113. For example, the second region 1112 may be disposed on the same side of the first region 1111 and the third region 1113 such that the gantry 120 is located on the same side of the processing space 100a and the non-processing space 100b, thereby facilitating the movable switching of the spindle mechanism 200 between the processing space 100a and the non-processing space 100 b.

In order to ensure the detection precision and accuracy of tool setting gauge 400 on the tool, tool setting gauge 400 is fixedly mounted on first boss 112.

Through fixing tool setting gauge 400 on first boss 112, spindle unit 200 activity sets up in portal frame 120, then, the most vibrations that the in-process of spindle unit 200 operation produced transmit to portal frame 120, and absorb the consumption and weaken via portal frame 120, little part vibrations are transmitted to base 110 through portal frame 120, because tool setting gauge 400 sets up in the first boss 112 of the first region 1111 of base 110, the vibrations that the in-process of spindle unit 200 operation produced need the longer distance of passing through to tool setting gauge 400, and vibrations are reduced by a wide margin via portal frame 120 and base 110 in the transmission process, can transmit to tool setting gauge 400 the vibrations weak, the influence to tool setting gauge 400 is very little, can guarantee the detection precision and the accuracy of tool setting gauge 400.

Alternatively, in order to ensure smooth operation of the spindle mechanism 200 for the tool changing operation, the tool changing mechanism 300 may be fixedly mounted on the first boss 112.

Similarly, by fixing the tool changing mechanism 300 to the first boss 112, the spindle mechanism 200 is movably disposed on the gantry 120, so that most of the vibration generated during the operation of the spindle mechanism 200 is transmitted to the gantry 120 and is absorbed and consumed by the gantry 120 to be attenuated, and a small part of the vibration is transmitted to the base 110 through the gantry 120, and since the tool changing mechanism 300 is disposed on the first boss 112 of the first region 1111 of the base 110, the vibration generated during the operation of the spindle mechanism 200 is transmitted to the tool changing mechanism 300 and needs to travel a longer distance, and the vibration is greatly reduced during the transmission process through the gantry 120 and the base 110, the vibration transmitted to the tool changing mechanism 300 is weak, the influence on the tool changing mechanism 300 is small, the accurate alignment of the spindle mechanism 200 and the tool changing mechanism 300 can be ensured, and the occurrence of abnormality during the tool changing of the spindle mechanism 200 is prevented.

Referring to fig. 1 and 2, the machine body 100 includes a first housing 130 and a second housing 140. The first housing 130 is provided with a processing space 100a, the second housing 140 is disposed in the first housing 130, the second housing 140 is disposed on one side of the processing space 100a along the first direction, the second housing 140 is provided with a non-processing space 100b, the second housing 140 is provided with an opening 140a, and the opening 140a communicates the processing space 100a with the non-processing space 100b. Wherein, the isolation door 500 is movably disposed at the opening 140a to expose or cover the opening 140a.

The first casing 130 may be a part of a housing, where the first casing 130 is fixedly connected with the base 110, and a processing space 100a is formed by enclosing the first casing 130 with the base 110. The first housing 130 may be provided with a notch 130a to communicate the processing space 100a with the external environment such that an operator may take and place a workpiece into the processing space 100a through the notch 130 a. It will be appreciated that the housing may include a protective door (not shown) movably disposed at the notch 130a to expose or cover the notch 130a, and the protective door may cover the notch 130a when the spindle mechanism 200 processes the workpiece in the processing space 100a, thereby isolating the processing space 100a from the external environment and preventing the workpiece, chip or cutter in the processing space 100a from flying out of the notch 130a during abnormal processing to cause production accidents.

The second housing 140 is used to form the non-processing space 100b. Specifically, the second casing 140 may be fixedly connected to the base 110, and encloses the non-processing space 100b with the base 110. The second housing 140 is further configured to form an opening 140a, wherein the shape of the opening 140a can be designed to match the contour shape of the spindle mechanism 200 to prevent interference with the second housing 140 during movement of the spindle mechanism 200.

It can be appreciated that the second casing 140 may also be used as a supporting component of the isolation door 500, where the isolation door 500 may be movably connected with the second casing 140 through a movement mechanism (such as a rotating shaft or a sliding rail), so that the isolation door 500 is more stable and smoother to switch between the blocking state and the communicating state.

To achieve the movable connection of the spindle mechanism 200 with the gantry 120, the spindle mechanism 200 may be slidably connected with the gantry 120 through the first slide rail assembly 910, such that the spindle mechanism 200 may slide along the first slide rail assembly 910 to move back and forth between the processing space 100a and the non-processing space 100 b.
