Technical Field
[0001] The present application relates to the technical field of trenchless dragging pipe construction, and in particular to a machining center capable of automatically clearing chips during machining. Background Art
[0002] The machining center is a type of CNC milling machine. Since it is equipped with a rotary tool holder and a tool changing robot, the machining center can perform multiple processes on the workpiece in one processing.
[0003] Generally, during the machining of workpieces, it is necessary to spray coolant on the tool to assist in the heat dissipation of the tool to prevent the high temperature during the machining process from damaging the tool. Since the debris generated during the machining process will affect the machining of the workpiece by the drill, and too much debris will also affect the operation of various feed screws in the machining center, the operator needs to use a high-pressure air gun to blow away the debris on the surface of the machining table after machining each workpiece, which increases the operator's operating burden.
[0004] In view of this, a machining center with automatic chip removal during machining is needed. Summary of the invention
[0005] In order to improve the problem of frequent manual processing of debris, which places heavy workload on operators, the present application provides a machining center that automatically clears chips during machining.

The workbench is provided with a sweeping unit, and both ends of the workbench are provided with collecting circulation units suitable for accommodating debris and coolant. The sweeping unit can sweep the debris on the workbench into the collecting circulation unit, and separate the debris and coolant through the collecting circulation unit.
[0008] By adopting the above technical solution, the debris attached to the workpiece generated during the milling process will fall onto the workbench under the action of the coolant sprayed from the spray pipe, and then the coolant and the debris will enter the collection circulation unit under the action of the sweeping unit to realize automatic cleaning and collection of the coolant and the debris. As a result, there is no need to use a high-pressure air gun to clean the debris in the machining center after the machining is completed, which reduces the workload of the operator, and the collected coolant and debris can be separated under the action of the collection circulation unit to realize classified collection and storage.
[0009] Furthermore, the cleaning unit includes a driving motor, a screw, a rotating motor and a rotating brush roller, the screw being rotatably connected to the workbench and extending along the length direction of the workbench, the driving motor being connected to the workbench and being transmission-connected to the screw, the rotating motor being connected to the screw and the workbench, the rotating motor being capable of moving along the screw when the screw rotates, the rotating motor being transmission-connected to the rotating brush roller and being capable of driving the rotating brush roller to rotate, and the rotating brush roller being capable of abutting against the upper surface of the workbench.
[0010] By adopting the above technical scheme, the rotation of the screw can drive the rotating motor and the rotating brush roller to move back and forth along the length direction of the workbench, and the rotating motor can drive the rotating brush roller to rotate so that the rotating brush roller can perform reciprocating cleaning on the workbench, thereby cleaning the debris on the workbench.
[0011] Furthermore, the collection circulation unit comprises a collection tank and a screen is provided in the collection tank, so that the collection tank is divided into an upper collection chamber and a lower collection chamber via the screen, the upper collection chamber is suitable for accommodating debris, and the lower collection chamber is suitable for accommodating coolant.

[0013] Furthermore, the screen is arranged at an angle, and a discharge port is provided on the side wall of the collecting trough at a lower position of the upper collecting cavity.
[0014] By adopting the above technical solution, the inclined setting of the screen can increase the area for filtering the coolant, thereby improving the filtering efficiency of the coolant, and opening a discharge port at a low position of the collection chamber can facilitate the discharge of debris.
[0015] Furthermore, a magnetic adsorption device is provided in the lower collecting chamber, and the magnetic adsorption device is configured to adsorb debris in the coolant.
[0016] By adopting the above technical solution, when processing iron workpieces, fine debris in the coolant can be effectively filtered out, so that the quality of the recovered coolant is higher.
[0017] Furthermore, the liquid spraying pipes are provided in plurality, and the liquid spraying pipes can be communicated with the lower collecting chamber.
[0018] By adopting the above technical solution, the amount of coolant sprayed can be larger, the cooling effect on the props can be better, and the large amount of coolant sprayed can be used to flush the tool and the workpiece to flush the debris attached to the tool and the workpiece onto the workbench to facilitate the collection of the debris.
[0019] Furthermore, the spindle box is also provided with an air jet pipe, and the air jet pipe is arranged at a side of the drill fixture away from the tool holder.
[0020] By adopting the above technical solution, since the coolant has a certain tension after flushing, when the spraying of the coolant is stopped, the debris entrained in the coolant slowly flowing on the surface of the workpiece will continue to adhere to the surface of the workpiece under the action of the tension of the coolant, and the jet pipe can use gas to blow off the debris and coolant attached to the surface of the workpiece.
[0021] Furthermore, the air injection pipe is an arc-shaped pipe, and a plurality of air outlets are provided on a side of the air injection pipe facing the drill fixture.
[0022] By adopting the above technical solution, when using gas to blow off the debris and coolant attached to the surface of the workpiece, it is only necessary to drive the jet pipe to move up and down to achieve comprehensive jet cleaning of the workpiece.
[0023] In summary, the present application includes at least one of the following beneficial effects:
[0024] 1. The chips attached to the workpiece generated during the milling process will fall onto the workbench under the action of the coolant sprayed from the spray pipe, and then the coolant and chips will enter the collection circulation unit under the action of the sweeping unit to achieve automatic cleaning and collection of the coolant and chips. Therefore, after the processing is completed, there is no need to use a high-pressure air gun to clean the chips in the machining center, which reduces the workload of the operator. The collected coolant and chips can be separated under the action of the collection circulation unit to achieve classified collection and storage;
[0025] 2.

[0032] A drill fixture 21 and a liquid spray pipe 22 are provided on the spindle box 2. The liquid spray pipe 22 is provided on the side of the drill fixture 21 away from the tool holder 4 so as not to interfere with tool changing. A sweeping unit 5 is provided on the workbench 3, and collecting circulation units 6 suitable for accommodating debris and coolant are provided at both ends of the workbench 3. The sweeping unit 5 can sweep the debris on the workbench 3 into the collecting circulation unit 6, and separate the debris and coolant through the collecting circulation unit 6.
[0033] The chips attached to the workpiece generated during the milling process will fall onto the workbench 3 under the action of the coolant sprayed from the spray pipe 22, and then the coolant and the chips will enter the collection circulation unit 6 under the action of the sweeping unit 5 to realize automatic cleaning and collection of the coolant and the chips. As a result, there is no need to use a high-pressure air gun to clean the chips in the machining center after the machining is completed, which reduces the workload of the operator, and the collected coolant and chips can be separated under the action of the collection circulation unit 6 to realize classified collection and storage.
[0034] Figure 3 yes Figure 1 Enlarged view of area B, see Figure 1 and Figure 3 The cleaning unit 5 can be configured to include a driving motor 51, a screw 52, a rotating motor 53 and a rotating brush roller 54. The screw 52 is rotatably connected to the workbench 3 and extends along the length direction of the workbench 3. The driving motor 51 is connected to the workbench 3 and is transmission-connected to the screw 52. The rotating motor 53 is connected to the screw 52 and the workbench 3. The rotating motor 53 can move along the screw 52 when the screw 52 rotates. The rotating motor 53 is transmission-connected to the rotating brush roller 54 and can drive the rotating brush roller 54 to rotate. The rotating brush roller 54 can abut against the upper surface of the workbench 3, so that the driving motor 51 can drive the screw 52 to rotate to drive the rotating motor 53 and the rotating brush roller 54 to reciprocate along the length direction of the workbench 3, and the rotating brush roller 54 is driven by the rotating motor 53 to rotate so as to realize the reciprocating cleaning of the rotating brush roller 54 on the workbench 3, thereby realizing the cleaning of the debris on the workbench 3.

The tilted setting of the screen 62 can increase the area for filtering the coolant, thereby improving the filtering efficiency of the coolant, and the discharge port 611 is opened at the low position of the collecting chamber to facilitate the discharge of debris.
[0036] In addition, if the machining center needs to process iron workpieces, a magnetic adsorption device 63 can be set in the lower collection chamber. The magnetic adsorption device 63 can be an electromagnet, so that it can adsorb iron debris in the coolant, thereby effectively filtering out fine debris in the coolant, so that the quality of the collected coolant is higher, so that it can achieve recycling quality.
[0037] See also Figure 1 and Figure 2 The liquid spraying pipe 22 can be provided in multiple pieces, so that the amount of coolant sprayed can be larger, and the cooling effect on the props can be better.
