Description

Technical Field

[0001] The present invention relates to the technical field of numerical control equipment, and particularly relates to a numerical control machining center with a high bed body and convenient chip removal. Background Art

[0002] A numerical control machining center is a numerical control machine tool with a tool magazine and capable of automatically changing tools to perform various machining operations on workpieces. When the numerical control machine tool processes workpieces, waste chips will inevitably be generated. These waste chips accumulate on the workbench and will have an adverse impact on the subsequent workpiece machining. Therefore, it is necessary to regularly discharge and output these waste chips. In the prior art, a plurality of T-shaped grooves are generally arranged in an array along the width direction on the surface of the workbench. Fixtures are installed in the T-shaped grooves through T-shaped bolts. During the workpiece machining process, the waste chips are not only located on the surface of the workbench but also easily fall into the T-shaped grooves. Due to the shape of the T-shaped grooves and the obstruction of the T-shaped bolts, it is very difficult to clean out the waste chips that fall into the T-shaped grooves. Based on this, the present invention proposes a numerical control machining center with a high bed body and convenient chip removal. Summary of the Invention

[0007] As a further improvement and optimization of the present invention, guide rods are inlaid on the groove walls of the T-shaped grooves, and guide grooves are arranged on the outer surface of the cleaning seat. Through the cooperation of the guide grooves and the guide rods, the sliding connection between the cleaning seat and the T-shaped grooves is realized.

[0008] As a further improvement and optimization of the present invention, the traction member is a conveyor belt or a synchronous belt that is power-connected to the second motor. The upper surface of the traction member is in contact with the lower orifice of the connection hole. The bottom of the cleaning seat is provided with a lug, and the bottom of the lug passes through a through-hole provided on the traction member, and the lug is fixedly connected to the traction member.

[0009] As a further improvement and optimization of the present invention, the conveyor belt or the synchronous belt is made of a wound sheet steel strip.

[0010] As a further improvement and optimization of the present invention, the cleaning seat is composed of two sub-seats. Each of the bottoms of the two sub-seats is provided with a lug, and each of the opposite sides of the two lugs is provided with a bottom hole;

[0011] The sub-seat is U-shaped. Inner grooves are provided in both side walls of the sub-seat along the width direction. Spray holes are provided on both inner sides of the sub-seat along the width direction. A plurality of spray holes are arranged along the length direction of the T-shaped groove, and the spray holes are arranged obliquely. The direction of the airflow ejected through the spray holes and the direction of the displacement component of the cleaning seat for cleaning the waste chips in the T-shaped groove along the length direction of the T-shaped groove are the same;

[0012] Both opposite sides of the two sub-seats are provided with connection grooves for communicating the inner groove and the bottom hole. A connecting pipe is connected to the outer surface of the lug, and the connecting pipe communicates with the bottom hole.

[0013] As a further improvement and optimization of the present invention, an intermediate convex strip extends at the middle position of the inner side surface of the sub-seat along the depth direction of the T-shaped groove. The two side surfaces of the intermediate convex strip along the width direction of the sub-seat are in the shape of an arc with a central angle of 90 degrees.

[0014] As a further improvement and optimization of the present invention, the chip cleaning member further includes a pulley and a winding wheel. A torsion spring is provided at the installation position of the winding wheel. The connecting pipe is wound around the winding wheel and one end passes around the pulley and is connected to the lug. The other end of the connecting pipe is fixed to the winding wheel and is connected to a blower or an air compressor through a rotary joint.

[0015] As a further improvement and optimization of the present invention, a supporting mechanism is provided on the bed body. The supporting mechanism includes two groups of supporting members respectively located on both sides of the workbench along the length direction;

[0016] The supporting member includes a side frame connected to the bed body through an oil pipeline. A number of supporting units are arranged in an array along the length direction of the workbench on the side frame.

[0017] As a further improvement and optimization of the present invention, the supporting unit includes a fixed core column fixedly arranged on the side frame parallel to the width direction of the workbench. An activity sleeve column is sleeved outside the fixed core column. An insertion column is provided on the side of the activity sleeve column facing the workbench. A slot corresponding to the insertion column is provided on the side surface of the workbench along the width direction. Initially, the insertion column is inserted into the slot;

[0018] The end face of the fixed core column is penetrated with oil holes, and the oil holes are connected to the oil pipeline. An outer bracket extends from the outer surface of the movable sleeve column. A first spring is arranged between the outer bracket and the side frame. The elastic force of the first spring is used to drive the outer bracket and the movable sleeve column to move away from the workbench. The end of the oil pipeline is connected to the hydraulic system.

[0019] As a further improvement and optimization of the present invention, a pressure supplement component is arranged on the oil pipeline. The pressure supplement component includes a valve housing. A valve core is sleeved inside the valve housing. One end of the valve housing is connected to the oil pipeline and an electromagnetic valve is arranged at the connection. A second spring is arranged between the valve core and the other end of the valve housing. Initially, the second spring is in a compressed state.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this solution, a side baffle extends upward on one side of the workbench along the length direction. The side baffle can indirectly increase the height of the bed body, effectively improving the overall rigidity and stability of the machine tool, making the stability during the processing better. At the same time, the structural design of the high bed body makes the chips generated by cutting easier to discharge, reducing the accumulation of chips in the processing area, avoiding the influence on the processing accuracy, and improving the processing efficiency and product quality.

[0022] 2. In this solution, the workbench is rotated 180 degrees so that the notch of the T-shaped groove faces downward, facilitating the dropping of waste chips. Then, through the movement of the cleaning seat and the air jet action of the spray holes, the cleaning of the T-shaped groove is realized. At the same time, the cooperation of the air jet action and the middle rib can also realize the cleaning of the T-shaped bolt. Therefore, this solution can achieve the thorough cleaning of the T-shaped groove, and the cleaning effect is better;

[0023] 3. In this solution, the support and limit of the workbench are realized through the supporting mechanism, making the workbench more stable during use. On this basis, the setting of the pressure supplement component can, when the oil pipeline leaks oil after a long time, on the one hand, play a role in supplementing pressure, so that the stability of the workbench is not affected in a short time, thus not affecting the workpiece being processed, and on the other hand, can send out a warning signal through the sensor.

Detailed implementation manners

[0040] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0041] Embodiment 1

[0042] Referring to Figure 1 and Figure 2 , a numerically controlled machining center with a high bed for easy chip removal, includes a workbench 200. On one side of the workbench 200 extending upward along the length direction, there is a side baffle 100. During the numerical control machining of workpieces, due to the existence of the side baffle 100, it can prevent waste chips from splashing and flying everywhere, so that the waste chips remain on the workbench 200.

[0043] The structure of the side baffle 100 can indirectly increase the height of the bed, effectively improving the overall rigidity and stability of the machine tool, making the stability during the machining process better. At the same time, the structural design of the high bed makes the chip generated by cutting easier to discharge, reducing the accumulation of chips in the machining area, avoiding the influence on the machining accuracy, and improving the machining efficiency and product quality.

[0044] Embodiment 2

[0045] Referring to Figures 3 - 6 and Figures 9 - 14 , the workbench 200 is rotatably connected to the bed of the numerically controlled machining center, and the rotating shaft formed at the rotating connection is in power connection with a first motor 300 arranged on the bed through a worm and worm gear. When chip cleaning is required, the workbench 200 is driven by the first motor 300 to rotate 180 degrees, so that the T-shaped groove 203 arranged on the workbench 200 and the T-shaped bolt 201 installed in the T-shaped groove 203 face downward. The waste chips on the workbench surface of the workbench 200 directly fall downward. For the waste chips in the T-shaped groove 203, part of them directly fall downward through the notch, and the remaining part is restricted by the shape of the T-shaped groove 203 and blocked by the T-shaped bolt 201, and will remain in the T-shaped groove 203 or fall on the end face of the T-shaped bolt 201. Therefore, this part of the waste chips needs to be cleaned. Specifically, a chip cleaning mechanism 400 is arranged on the workbench 200 for cleaning the waste chips in the T-shaped groove 203.

[0046] Referring to Figure 10 , a bottom groove 204 parallel to the T-shaped groove 203 and located below the T-shaped groove 203 is arranged in the workbench 200. The bottom groove 204 is connected to the T-shaped groove 203 through a connection hole, and a plurality of bottom grooves 204 and connection holes corresponding to the T-shaped groove 203 are provided.

[0047] Referring to Figure 11 , the chip cleaning mechanism 400 includes a second motor 401 and a chip cleaning component, and multiple groups of chip cleaning components corresponding to the T-shaped groove 203 are provided.

[0048] Referring to Figures 12 - 14 , the chip cleaning component includes a traction component 402 arranged in the bottom groove 204 and a cleaning seat 403 slidably arranged in the T-shaped groove 203. The traction component 402 is used to traction the cleaning seat 403 to move in the T-shaped groove 203. Further, guide rods 408 are inlaid on the groove walls of the T-shaped groove 203, and guide grooves are arranged on the outer surface of the cleaning seat 403. Through the cooperation of the guide grooves and the guide rods 408, the sliding connection between the cleaning seat 403 and the T-shaped groove 203 is realized. Further, the traction component 402 can be a conveyor belt technology or a synchronous belt technology, and its upper surface fits with the lower orifice of the connection hole. A lug 4032 is arranged at the bottom of the cleaning seat 403, and the bottom of the lug 4032 passes through the through hole arranged on the traction component 402. The lug 4032 and the traction component 402 are fixedly connected by existing technologies such as screws. In this way, the cleaning seat 403 can be tractioned to move by the traction component 402, and the lower orifice of the connection hole remains blocked. Preferably, the conveyor belt technology or the synchronous belt technology is generally made of rubber material, and waste chips are easy to be hooked. Therefore, the conveyor belt or the synchronous belt can be selected to be made of a rolled-up sheet steel strip, which is made of elastic metal and has a smooth surface, and waste chips are not easy to be hooked. In addition, the second motor 401 is used to drive the pulley of the conveyor belt or the synchronous belt to rotate, so as to drive the traction component 402 to operate.

[0049] The cleaning seat 403 is composed of two sub-seats 4031. A lug 4032 is arranged at the bottom of each of the two sub-seats 4031, and a bottom hole 4033 is arranged on one side of each of the two lugs 4032 facing each other.

[0050] Since it is necessary to avoid the T-shaped bolt 201 and fit with the T-shaped groove 203, the sub-seat 4031 is U-shaped. Inner grooves 4035 are arranged in both side walls of the sub-seat 4031 along the width direction. Spray holes 4036 are arranged on both inner sides of the sub-seat 4031 along the width direction. A plurality of spray holes 4036 are arranged along the length direction of the T-shaped groove 203, and the spray holes 4036 are arranged obliquely. The direction of the airflow ejected through the spray holes 4036 is consistent with the moving direction of the cleaning seat 403 when cleaning the waste chips in the T-shaped groove 203 in the component displacement direction in the length direction of the T-shaped groove 203.

[0051] Connection grooves 4034 are arranged on one side of each of the two sub-seats 4031 facing each other. The connection grooves 4034 are used for communicating the inner grooves 4035 and the bottom holes 4033. A connecting pipe 409 is connected to the outer surface of the lug 4032, and the connecting pipe 409 is communicated with the bottom hole 4033.

[0052] The working process of the chip cleaning component is specifically as follows:

[0053] When it is necessary to clean up the waste chips, first, the workbench 200 is driven by the first motor 300 to rotate 180 degrees, so that the notch of the T-shaped groove 203 faces downward, and part of the waste chips fall downward;

[0054] Then, the traction component 402 is driven to operate by the second motor 401, so as to drive the cleaning seat 403 to move in the T-shaped groove 203. At the same time, driven by a blower or an air compressor, etc., air enters the inner groove 4035 through the connecting pipe 409, the bottom hole 4033, and the connecting groove 4034, and then is ejected through the ejection holes 4036. Through the movement of the cleaning seat 403 and the action of ejecting air outward through the ejection holes 4036, the waste chips in the T-shaped groove 203 are cleaned, and the cleaned waste chips fall downward through the notch of the T-shaped groove 203.

[0055] Further, referring to Figure 14 In the middle position of the side surface of the sub-seat 4031 along the depth direction of the T-shaped groove 203 and located inside, an intermediate ridge 410 extends. The two side surfaces of the intermediate ridge 410 along the width direction of the sub-seat 4031 are in the shape of an arc surface with a central angle of 90 degrees. The significance is that due to the presence of the T-shaped bolt 201, after the workbench 200 rotates 180 degrees, part of the waste chips pass through the notch and fall directly downward, and the remaining waste chips are restricted by the shape of the T-shaped groove 203 and the obstruction of the T-shaped bolt 201, and either remain in the T-shaped groove 203 or fall on the end surface of the T-shaped bolt 201. Therefore, in order to clean the waste chips thoroughly, it is also necessary to clean the end surface of the T-shaped bolt 201. Specifically, part of the air flow ejected through the ejection holes 4036 will contact the arc surface and flow downward along the arc surface. When the cleaning seat 403 passes by the T-shaped bolt 201, this part of the downward flowing air flow will blow and clean the end surface of the T-shaped bolt 201.

[0056] In a preferred embodiment, referring to Figure 12 and Figure 13 initially, the cleaning seat 403 is located at one end of the T-shaped groove 203. An inner seat 404 is internally and fittingly arranged in the cleaning seat 403, and the inner seat 404 is fixedly connected to the T-shaped groove 203. The significance is that when not in use, the cleaning seat 403 is blocked by the inner seat 404. On the one hand, it prevents waste chips from splashing into the cleaning seat 403. On the other hand, after the T-shaped groove 203 is cleaned of waste chips, the inner seat 404 can be used to clean the cleaning seat 403 to prevent waste chips from sticking inside the cleaning seat 403.

[0057] In a preferred embodiment, since the cleaning seat 403 needs to move during waste chip cleaning, in order to place the connecting pipe 409 in an orderly manner, referring to Figure 12, the chip cleaning member further includes a pulley 405 and a wire winding wheel 406. A torsion spring 407 is provided at the installation position of the wire winding wheel 406. The connecting pipe 409 is wound inside the wire winding wheel 406 and one end thereof bypasses the pulley 405 and is connected to the lug 4032. Further, since the connecting pipe 409 is orderly placed by the winding and unwinding of the wire winding wheel 406, therefore, the other end of the connecting pipe 409 should be fixed to the wire winding wheel 406, that is, the connecting pipe 409 needs to be connected to the blower or air compressor through a rotary joint, which can be achieved by the prior art and will not be elaborated herein.

[0058] Embodiment III

[0059] In Embodiment II, although the power connection between the first motor 300 and the workbench 200 is achieved through a worm and worm gear, and the worm and worm gear has self-locking property, Embodiment III is proposed for the sake of the stability of the workbench 200 during workpiece processing.

[0060] Referring to Figures 6 - 9 , a supporting mechanism 500 is provided on the bed of the CNC machining center. The supporting mechanism 500 includes two groups of supporting members respectively located on both sides of the workbench 200 along the length direction.

[0061] The supporting member includes a side frame 501 connected to the bed by an oil pipeline 503. A plurality of supporting units 502 are arranged in an array along the length direction of the workbench 200 on the side frame 501.

[0062] The supporting unit 502 includes a fixed core column 5021 parallel to the width direction of the workbench 200 and fixedly arranged on the side frame 501. An activity sleeve column 5022 is sleeved outside the fixed core column 5021. An insertion column 5024 is arranged on the side of the activity sleeve column 5022 facing the workbench 200. A slot 202 facing the insertion column 5024 is arranged on the side surface of the workbench 200 along the width direction. Initially, the insertion column 5024 is inserted into the slot 202.

[0063] An oil hole is penetrated through the end surface of the fixed core column 5021 and is connected to the oil pipeline 503. In addition, an outer bracket extends from the outer surface of the activity sleeve column 5022. A first spring 5023 is arranged between the outer bracket and the side frame 501. The elastic force of the first spring 5023 is used to drive the outer bracket and the activity sleeve column 5022 to move away from the workbench 200.

[0064] The end of the oil pipeline 503 is connected to a hydraulic system. The hydraulic system can be achieved by the prior art and will not be elaborated herein. Through the cooperation of the hydraulic system and the first spring 5023, the activity sleeve column 5022 can be driven to move, so as to drive the insertion column 5024 to insert into or leave the slot 202. The former can make the workbench 200 more stable during workpiece processing, and the latter is for avoiding chip cleaning of the workbench 200.

[0065] In a preferred embodiment, after long-term use, oil leakage will inevitably occur in the oil pipeline 503 and the supporting unit 502. In order not to affect the workpiece being processed and to play a role in self-checking and reminding, refer to Figure 8 , a pressure compensation component 504 is provided on the oil pipeline 503. Further, the pressure compensation component 504 includes a valve housing 5041, a valve core 5042 is sleeved inside the valve housing 5041, one end of the valve housing 5041 is connected to the oil pipeline 503 and a solenoid valve 5044 is provided at the connection, and a second spring 5043 is provided between the valve core 5042 and the other end of the valve housing 5041. Initially, the elastic coefficient of the second spring 5043 is large and in a compressed state, and the solenoid valve 5044 is opened. If oil leakage occurs in the oil pipeline 503 and the supporting unit 502, then the second spring 5043 will release its elastic force to play a role in pressure compensation, enabling the workpiece being processed to be successfully processed. A sensor for monitoring the elastic force of the second spring 5043 can be provided inside the valve housing 5041. When oil leakage occurs and the second spring 5043 releases its elastic force to achieve pressure compensation, the data monitored by the sensor fluctuates greatly and a signal is sent. After the workpiece being processed is finished, the machine is immediately stopped for inspection and maintenance. In addition, when discharging chips, the solenoid valve 5044 is closed in advance.

[0066] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
