A chip collection device for CNC machining

Abstract

The present invention is applicable to the technical field related to machining auxiliary devices, and provides a chip collection device for CNC machining, including a base, a first box body arranged on the upper part of the base, and a second box body arranged on the upper part of the first box body. When in use, the pumping mechanism works, so that the absorption head absorbs the flying chips into the first box body. At the same time, the driving mechanism drives the movable plate to drive the absorption head to swing back and forth. During the reciprocating swing of the absorption head, the retraction mechanism is triggered, so that the slider drives the absorption head in the slide groove on the movable plate toward the rotation center of the movable plate. During this process, the elastic component stores elastic potential energy. When the absorption head moves to the maximum stroke, the elastic component releases the elastic potential energy, and the absorption head and the slider reset at the same time. This reciprocating movement and reciprocating movement of the absorption head are carried out simultaneously, which greatly improves the absorption range of the flying chips and significantly improves the effect of collecting the flying chips.

Description

Technical Field

[0001] The present invention belongs to the technical field related to machining auxiliary devices, and in particular relates to a chip collection device for CNC machining. Background Art

[0002] Numerical control technology, abbreviated as CNC, is a technology that uses digital control methods to achieve automatic control of a certain work process. It usually controls mechanical quantities such as position, angle, speed, and switching quantities related to the flow of mechanical energy. The emergence of CNC depends on the emergence of data carriers and binary data operations. CNC technology is the base for the manufacturing industry to achieve automated, flexible, and integrated production. It is the core of modern manufacturing technology and an indispensable and important means to improve product quality and labor productivity in the manufacturing industry.

[0003] CNC machining refers to a process method for processing parts on CNC machine tools. CNC machine tools are machine tools controlled by computers. The computers used to control machine tools, whether they are special-purpose computers or general-purpose computers, are collectively referred to as CNC systems. The movement and auxiliary actions of CNC machine tools are all controlled by the instructions issued by the CNC system. The basic components of CNC machine tools include processing program carriers, CNC devices, servo drive devices, machine tool bodies and other auxiliary devices.

[0004] During CNC machining, the part of the workpiece that needs to be machined is removed under the action of the cutting force of the tool, and in the process, chips are caused to fly around the workpiece. In order to prevent the flying chips from affecting the machining process, a corresponding flying chip collection device is usually used. However, when the existing flying chip collection device is used, the position of the flying chip absorption is usually fixed, which makes the range smaller, resulting in poor chip collection effect.

[0006] The present invention is implemented as follows: the chip collection device for CNC machining includes a base, a first box body arranged on the upper part of the base, and a second box body arranged on the upper part of the first box body, a through opening is opened on the side of the first box body, and a flip cover is provided at the through opening. The chip collection device for CNC machining also includes:

[0007] A movable plate, the movable plate being rotatably mounted on a side portion of the first box body and being parallel to the side surface thereof, the movable plate being provided with a slide groove, a slider being slidably engaged in the slide groove, and a group of elastic components connected to the slider being provided on each side of the movable plate;

[0008] an absorption head, the absorption head being mounted on the slider and connected to a pumping mechanism disposed in the second box;

[0009] A driving mechanism, the driving mechanism being installed in the second box and connected to the pumping mechanism, and the pumping mechanism driving the driving mechanism to drive the movable plate and the absorbing head to swing back and forth when in operation;

[0010] The retracting and extending mechanism is installed on the movable plate, and triggers and drives the slider and the absorbing head to move back and forth along the movable plate during the reciprocating swing of the movable plate.

[0011] Furthermore, the pumping mechanism includes an air pump installed in the second box body and a drive motor installed on the outer wall of the second box body. The drive shaft of the air pump is connected to the drive mechanism through a bevel gear set, and its air inlet is connected to the absorption head through a hose, and the air outlet is connected to a transmission pipe, which extends into the first box body.

[0012] Furthermore, the driving mechanism includes a rotating component and a toothing component installed on the inner wall of the second box body. The rotating component is connected to the end of the air pump drive shaft through the bevel gear set. The toothing component drives the movable plate to swing back and forth during the process of cooperating with the rotating component.

[0013] Furthermore, the engaging assembly includes a cross bar fixed on the inner wall of the second box body, a rack plate slidably arranged on the cross bar, and a first gear located inside the second box body and coaxially fixed with the movable plate, and the first gear meshes with the teeth on the rack plate.

[0014] Furthermore, the rotating assembly includes a disc rotatably mounted in the second housing, a fixing column disposed on an eccentric portion of the bottom of the disc and perpendicular thereto, and two limiting plates fixed to the rack plate;

[0015] A gap is reserved between the two limiting plates, and the fixing column extends into the gap. The end of the disc rotating shaft is connected to the end of the air pump driving shaft through the bevel gear set.

[0016] Furthermore, the elastic component includes a fixed rod arranged on the side of the movable plate, a moving block slidably arranged on the fixed rod and fixed to the slider, and a spring sleeved on the outer periphery of the fixed rod.

[0018] The rotating shaft of the second gear passes through the movable plate. The fixing member is a semi-annular structure. A plurality of tooth groups are arranged on the inner wall of the fixing member at equal intervals along the circumference. The tooth groups cooperate with the second gear.

[0019] Furthermore, the intermittent rotation assembly includes a line roller rotatably mounted on the side of the movable plate away from the second gear, the line roller is connected to the slider via a rope, and the rotation axis of the line roller is connected to the rotation axis of the second gear via a transmission belt.

At the same time, the pumping mechanism drives the driving mechanism to move, and the driving mechanism drives the movable plate to drive the absorption head to swing back and forth. During the reciprocating swing of the absorption head, the retraction mechanism is triggered, so that the slider drives the absorption head in the slide groove on the movable plate toward the rotation center of the movable plate. During this process, the elastic component stores elastic potential energy. When the absorption head moves to the maximum stroke, the elastic component releases the elastic potential energy, and the absorption head and the slider are reset at the same time. This reciprocating movement causes the reciprocating swing and reciprocating movement of the absorption head to proceed simultaneously. After the device is finished working, the flip cover is opened and the flying chips in the first box can be cleaned. In summary, through the mutual cooperation of various mechanisms, components and parts in the device, the multi-directional collection function of the absorption head for flying chips is realized, and because the position of the absorption head is constantly changing when the device is working, the absorption range of flying chips is greatly improved, and the effect of collecting flying chips is significantly improved.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] In order to effectively illustrate the embodiments of the present invention, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-5 The present invention provides a chip collection device for CNC machining to solve the problem that the existing flying chip collection device has a small collection range for flying chips.

[0033] The chip collection device for CNC machining includes a base 1, a first box body 2 arranged on the upper part of the base 1, and a second box body 3 arranged on the upper part of the first box body 2. A through opening is opened on the side of the first box body 2, and a flip cover 4 is provided at the through opening. The device also includes:

[0034] The movable plate 17 is rotatably mounted on the side of the first box body 2 and is parallel to the side thereof. A slide groove is provided on the movable plate 17, and a slider 18 is slidably engaged in the slide groove. A group of elastic components connected to the slider 18 are provided on each side of the movable plate 17.

[0035] The elastic component includes a fixed rod 23 provided on the side of the movable plate 17 , a moving block 24 slidably provided on the fixed rod 23 and fixed to the slider 18 , and a spring 25 sleeved on the outer periphery of the fixed rod 23 .

[0036] Specifically, two baffles are provided on each side of the movable plate 17 , and the fixing rod 23 is installed between the two baffles. In addition, one end of the spring 25 is connected to the moving block 24 , and the other end is connected to one of the baffles.

[0037] an absorption head 5, the absorption head 5 being mounted on the slider 18 and connected to a pumping mechanism disposed in the second box 3;

[0038] The driving mechanism is installed in the second box body 3 and is connected to the pumping mechanism. When the pumping mechanism is working, it drives the driving mechanism to drive the movable plate 17 and the absorption head 5 to swing back and forth.

[0039] The pumping mechanism includes an air pump 7 installed in the second box body 3 and a drive motor 6 installed on the outer wall of the second box body 3. The drive shaft of the air pump 7 is connected to the drive mechanism through a bevel gear set 8, and its air inlet is connected to the absorption head 5 through a hose 10, and the air outlet is connected to the transmission pipe 9, which extends into the first box body 2.

[0040] Since the flying chips generated during machining are generally at a high temperature, in order to keep the device working normally for a long time, the transmission pipe 9 and the hose 10 are both made of heat-resistant materials.

[0041] The driving mechanism includes a rotating component and a gearing component installed on the inner wall of the second box body 3. The rotating component is connected to the end of the driving shaft of the air pump 7 through the bevel gear set 8. The gearing component drives the movable plate 17 to swing back and forth during the process of cooperating with the rotating component.

[0042] The meshing assembly includes a cross bar 13 fixed on the inner wall of the second box body 3, a rack plate 14 slidably arranged on the cross bar 13, and a first gear 16 located inside the second box body 3 and coaxially fixedly installed with the movable plate 17, and the first gear 16 is engaged with the teeth on the rack plate 14.

[0043] The rotating assembly includes a disc 11 rotatably mounted in the second housing 3 , a fixing post 12 disposed on the bottom eccentric portion of the disc 11 and perpendicular thereto, and two limiting plates 15 fixed to the rack plate 14 ;

[0044] A gap is reserved between the two limiting plates 15 , and the fixing column 12 extends into the gap. The end of the rotating shaft of the disc 11 is connected to the end of the driving shaft of the air pump 7 through the bevel gear set 8 .

[0045] When the driving motor 6 drives the air pump 7 to work, the driving shaft of the air pump 7 drives the disc 11 to rotate through the bevel gear set 8. The fixed column 12 at the bottom of the disc 11 makes a circular motion, and the rack plate 14 slides back and forth on the cross bar 13 through the two limit plates 15. Therefore, the first gear 16 drives the movable plate 17 to swing back and forth.

[0046] Furthermore, the bevel gear set 8 mentioned above includes two bevel gears meshing with each other, namely a first bevel gear fixed to the end of the driving shaft of the air pump 7 and a second bevel gear fixed to the end of the rotating shaft of the disc 11.

[0047] The retracting and extending mechanism is installed on the movable plate 17 and triggers and drives the slider 18 and the absorbing head 5 to move back and forth along the movable plate 17 during the reciprocating swing of the movable plate 17.

[0048] The retractable mechanism includes an intermittent rotating assembly mounted on the movable plate 17 and an intermittent matching structure connected to the intermittent rotating assembly, the intermittent matching structure including a second gear 22 rotatably mounted on one side of the movable plate 17 and a fixing member 21 provided on the outer wall of the second box body 3;

[0049] The rotating shaft of the second gear 22 passes through the movable plate 17 . The fixing member 21 is a semi-annular structure, and a plurality of tooth groups are equidistantly arranged on the inner wall thereof along the circumference. The tooth groups cooperate with the second gear 22 .

[0050] The intermittent rotation assembly includes a line roller 19 rotatably mounted on the side of the movable plate 17 away from the second gear 22, the line roller 19 is connected to the slider 18 via a rope, and the rotation axis of the line roller 19 is connected to the rotation axis of the second gear 22 via a transmission belt 20.

[0051] In detail, a pulley is installed on the rotating shaft of the second gear 22 and the line roller 19, and the transmission belt 20 is used to connect the two pulleys, and the pulley diameter on the second gear 22 is larger than the pulley diameter on the second gear 22, so as to achieve a certain speed-increasing effect.

[0052] When the movable plate 17 swings, the second gear 22 cooperates with the tooth group on the fixed part 21 to rotate, and the rotating shaft of the second gear 22 drives the line roller 19 to rotate through the transmission belt 20, so that the line roller 19 winds up the rope, pulling the slider 18 and the absorbing head 5 toward the line roller 19 to make a linear motion. During this process, the moving block 24 slides on the fixed rod 23 and compresses the spring 25. After the second gear 22 is separated from the tooth group on the fixed part 21, the spring 25 rebounds in an instant, causing the slider 18 and the absorbing head 5 to reset. This cycle is repeated, so that the reciprocating swing and reciprocating linear motion of the absorbing head 5 are carried out simultaneously.

[0053] When in use, the device is carried to a suitable working position (the absorbing head 5 faces the processing machine tool), and the pumping mechanism works, so that the absorbing head 5 absorbs the flying chips generated during machining into the first box body 2. At the same time, the pumping mechanism drives the driving mechanism to move, and the driving mechanism drives the movable plate 17 to drive the absorbing head 5 to swing back and forth. During the reciprocating swing of the absorbing head 5, the retracting mechanism is triggered, so that the slider 18 drives the absorbing head 5 to move toward the rotation center of the movable plate 17 in the slide groove on the movable plate 17. During this process, the elastic component reserves elastic potential energy. When the absorbing head 5 moves to the maximum stroke, the elastic component releases the elastic potential energy, and the absorbing head 5 and the slider 18 are reset at the same time. This reciprocating process causes the reciprocating swing and reciprocating movement of the absorbing head 5 to be carried out simultaneously. After the device is finished working, the flip cover 4 is opened to clean the flying chips in the first box body 2.

[0054] Through the mutual cooperation of various mechanisms, components and parts in the device, the multi-directional collection function of the absorption head 5 on flying debris is realized. Moreover, since the position of the absorption head 5 is constantly changing when the device is working, the absorption range of flying debris is greatly improved, and the effect of collecting flying debris is significantly improved.

[0055] Taking the embodiment of the combination of all the features recorded in this application as an example, when in use, the device is moved to a suitable working position, the driving motor 6 drives the air pump 7 to work, and the air pump 7 absorbs the flying chips generated in the machining into the first box body 2 through the absorption head 5, the hose 10 and the transmission pipe 9. At the same time, the driving shaft of the air pump 7 drives the disc 11 to rotate through the bevel gear set 8, and the fixed column 12 at the bottom of the disc 11 makes a circular motion. The rack plate 14 slides back and forth on the cross bar 13 through the two limit plates 15. Therefore, the first gear 16 drives the movable plate 17 to swing back and forth. During the reciprocating swing of the absorption head 5, the second gear 22 and the fixed part 21 The tooth group cooperates and the gear rotates, and the rotating shaft of the second gear 22 drives the line roller 19 to rotate through the transmission belt 20, so that the line roller 19 winds up the rope, pulling the slider 18 and the absorption head 5 toward the line roller 19 for linear motion. During this process, the moving block 24 slides on the fixed rod 23 and compresses the spring 25. After the second gear 22 is separated from the tooth group on the fixed part 21, the spring 25 rebounds in an instant, causing the slider 18 and the absorption head 5 to reset. This cycle is repeated, so that the reciprocating swing and reciprocating linear motion of the absorption head 5 are carried out simultaneously. After the device is finished working, open the flip cover 4 and clean up the flying debris in the first box body 2.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
