Description

TECHNICAL FIELD

[0001] The present application belongs to the field of machine tool accessory equipment, and particularly relates to an auxiliary chip removal machine for machine tools. BACKGROUND

[0002] The chip removal machine is a kind of equipment for collecting and transporting various metal and non-metal chips generated in various machine tool machining, which is widely applied in combined machine tools and flexible flow lines in various numerical control machine tool machining. The chip removal machine includes a scraper type chip removal machine, a chain plate type chip removal machine, a magnetic chip removal machine and a spiral chip removal machine. The scraper type chip removal machine is widely applied in combined machine tools and flexible flow lines in various numerical control machine tool machining due to its small size and high efficiency.

[0003] When the scraper type chip removal machine operates, the chips entering from the chip inlet are pushed to the chip outlet by the back-and-forth operation of the scraper. When the scraper back-and-forth operates to the chip inlet, the mixed chips with cooling liquid falling from the machine tool will fall on the upper end of the scraper, causing the chips to adhere and stay on the upper end of the scraper. With the back-and-forth operation of the scraper, the adhered chips will gradually increase, causing the chips to be stuck between the housing and the scraper during the back-and-forth operation of the scraper, resulting in the scraper being stuck and affecting the chip removal work. In addition, the chips adhering and staying on the upper end of the scraper will continuously rub against the housing with the back-and-forth operation of the scraper, causing the housing to wear and shorten the service life. Secondly, although the scraper type chip removal machine has fine liquid discharge holes spaced apart to block the chips and prevent the chips from being discharged together with the cooling liquid, the fine chips are still easy to enter the fine liquid discharge holes and block the fine liquid discharge holes, affecting the discharge of the cooling liquid. SUMMARY

DETAILED DESCRIPTION

[0037] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] An auxiliary chip conveyor for machine tools, see Figures 1-4, including the blade type chip removal machine body, the blade type chip removal machine body is composed of shell 1, shell cover 2, baffle 3, rotating shaft 4, pulley 5, drive belt 6, scraper 7 and motor 71, both sides of shell 1 are open type, both sides of shell 1 are connected with shell cover 2, both shell cover 2 are connected with baffle 3, shell 1, shell cover 2 and baffle 3 contain low level section, inclined section and high level section from left to right, the top of low level section of shell 1 is provided with chip inlet, the bottom of high level section of shell 1 is provided with chip outlet, the lower part of both sides of low level section of shell 1 is spaced from left to right and provided with fine liquid discharge hole, the bottom of low level section of shell cover 2 is provided with liquid discharge port, the liquid discharge port is connected with liquid discharge groove 8, the liquid discharge groove 8 is tubular body, the low level section between the two shell cover 2 and the high level section between the two shell cover 2 are rotatably connected with rotating shaft 4, two drive belts 6 are symmetrically connected between the two rotating shaft 4 through pulley 5, pulley 5 is in contact with baffle 3, drive belt 6 is attached to baffle 3, and drive belt 6 is attached to the inner wall of shell 1, the cooperation between baffle 3, pulley 5 and drive belt 6 blocks the debris in shell 1 to avoid the debris entering shell cover 2, scraper 7 is connected between the two drive belts 6, motor 71 is installed at the high level section of front side shell cover 2, the output shaft of motor 71 is connected with rotating shaft 4 at high level section.

[0039] The chip removal machine is placed below the machine tool, and the liquid discharge groove 8 is connected with pipeline, the debris mixed with cooling liquid falling from the machine tool falls into the shell 1 through the chip inlet, the motor 71 drives the rotating shaft 4 connected therewith to rotate, so that the drive belt 6 drives the scraper 7 to run back and forth to push the debris to the chip outlet for discharge, the cooling liquid in the shell 1 is discharged to the shell cover 2 through the fine liquid discharge hole, while the debris is blocked by the fine liquid discharge hole to avoid being discharged with the cooling liquid, the cooling liquid in the shell cover 2 is discharged into the liquid discharge groove 8 through the liquid discharge port, and then discharged to the designated position through the pipeline.

[0040] When the scraper 7 runs back and forth to the chip inlet, the debris mixed with cooling liquid falling from the machine tool will fall on the upper end of the scraper 7, causing the debris to adhere and stay on the upper end of the scraper 7, and the adhered debris will gradually increase with the back and forth running of the scraper 7, so that the debris is stuck between the shell 1 and the scraper 7 during the back and forth running of the scraper 7, causing the scraper 7 to be stuck and affecting the chip removal work, and the debris adhering and staying on the upper end of the scraper 7 rubs the shell 1 continuously with the back and forth running of the scraper 7, causing the shell 1 to wear and shorten the service life.

[0041] In some preferred embodiments, referring to Figure 5-Figure 6The two cleaning rollers 92 are rotatably connected to the chip inlet of the housing 1, and the two cleaning rollers 92 are arranged on the left and right sides. The two cleaning rollers 92 are connected to the rotating shaft 4 at the low level section through a belt transmission assembly 93. The two belt transmission assemblies 93 are symmetrically arranged one before and one after. The front belt transmission assembly 93 is connected between the front side of the left cleaning roller 92 and the front side of the rotating shaft 4 at the low level section, and the rear belt transmission assembly 93 is connected between the rear side of the right cleaning roller 92 and the rear side of the rotating shaft 4 at the low level section. The belt transmission assembly 93 consists of two pulleys and a flat belt. The two pulleys are respectively connected to the rotating shaft 4 at the low level section and the cleaning roller 92. The flat belt is sleeved between the two pulleys. Two chip guide plates 91 are obliquely installed at the chip inlet of the housing 1, and the two chip guide plates 91 are symmetrically arranged front and back.

[0042] The chip guide plate 91 can guide the debris so that the debris slides along the chip guide plate 91 through the chip inlet into the shell 1, thereby preventing the debris from falling outside the shell 1 and being wasted, thereby improving the debris collection effect. In the process of the scraper 7 running back and forth to the chip inlet, the upper end of the scraper 7 will contact the cleaning roller 92, and the rotation of the rotating shaft 4 at the low horizontal section drives the cleaning roller 92 to rotate through the belt drive assembly 93. The rotation of the cleaning roller 92 can automatically clean the debris adhering to the upper end of the scraper 7 to prevent the debris from staying on the upper end of the scraper 7, thereby preventing the debris from getting stuck between the shell 1 and the scraper 7 during the back and forth operation of the scraper 7, causing the scraper 7 to get stuck and affect the chip removal work, and preventing the debris from continuously rubbing against the shell 1 during the back and forth operation of the scraper 7, causing the shell 1 to wear and shorten its service life.

[0043] In some preferred embodiments, see Figure 7-Figure 8 In order to avoid the situation where the fine drainage holes are blocked by fine debris and affect the discharge of coolant, it also includes a guide rod A101 and a connecting plate 102. The lower parts of the front and rear sides of the low horizontal section of the shell 1 are slidingly connected to the connecting plate 102 through the guide rod A101. Two springs 105 are symmetrically connected between the connecting plate 102 and the shell 1. The side of the connecting plate 102 facing the fine drainage hole is connected with a dredging rod 103 at intervals. The top of the connecting plate 102 is connected to a contact block 104. Five V-shaped push blocks 106 are connected to the two driving belts 6 at intervals. The V-shaped push blocks 106 can contact the contact block 104 by running back and forth and push the contact block 104 to move toward the direction close to the shell 1. It should be noted that the connecting plate 102, the dredging rod 103 and the contact block 104 constitute a dredging component.

[0044] The driving belt 6 rotates to drive the V-shaped push block 106 to rotate. When the V-shaped push block 106 rotates to contact the contact block 104, the V-shaped push block 106 continues to rotate to push the contact block 104 toward the shell 1 through the inclined surface thereon, so that the connecting plate 102 moves toward the shell 1 to push the dredging rod 103 into the fine drainage hole to dredge the fine drainage hole, so as to push out the fine debris in the fine drainage hole, thereby preventing the fine drainage hole from being blocked by fine debris and affecting the discharge of coolant.

[0045] The chips mixed with coolant dropped from the machine tool may adhere to and accumulate on the chip guide plate 91. In some preferred embodiments, see Figure 9-10 It is shown that in order to prevent debris from adhering to and accumulating on the chip guide plate 91, a guide rod B113 and a push plate 114 are also included. The upper end surface of the chip guide plate 91 is slidingly connected to the push plate 114 through the guide rod B113, and the lower end surface of the push plate 114 contacts the upper end surface of the chip guide plate 91. Electric push rods 112 are installed on the left and right sides of the chip guide plate 91, and the telescopic rods of the electric push rods 112 are connected to the push plate 114. The tops of the lower horizontal sections of the two shell covers 2 are connected with elastic cloths 111, and the two elastic cloths 111 are respectively connected to the two push plates 114. A scraper plate 115 is connected to the guide rod B113, and the scraper plate 115 is located on the upper side of the push plate 114.

[0046] The electric push rod 112 is controlled to make the push plate 114 move back and forth downward and upward along the upper end surface of the chip guide plate 91. The push plate 114 moves downward along the upper end surface of the chip guide plate 91 to push the chips on the chip guide plate 91 down into the housing 1 to prevent the chips from adhering to and accumulating on the chip guide plate 91. The push plate 114 moves downward to stretch the elastic cloth 111, which can catch the chips dropped from the machine tool through the elastic cloth 111 to prevent the chips dropped from the machine tool from falling on the chip guide plate 91 when the push plate 114 cleans the chips on the chip guide plate 91. The push plate 114 is moved upward to release the elastic cloth 111, and the elastic cloth 111 returns to its original shape. During this process, the upper end surface of the elastic cloth 111 contacts the scraper plate 115, and the scraper plate 115 scrapes off the debris falling on the upper end surface of the elastic cloth 111.

[0047] Smaller iron chips may be discharged along with the coolant through the fine drain holes, resulting in waste. In some preferred embodiments, see Figure 11-12 In order to avoid the waste of small iron filings when discharged with the coolant, it also includes a positioning block 123 connected to the right side of the drain trough 8, a magnetic bar 122 is placed in the drain trough 8, and a screw cover 121 is connected to the left side of the drain trough 8 by a threaded connection.

[0048] The magnetic bar 122 can adsorb the fine iron filings discharged through the fine liquid discharge hole under the magnetic force of the magnetic bar 122, so as to avoid waste of the fine iron filings discharged with the cooling liquid. The magnetic bar 122 can be clamped and positioned by the cooperation of the screw cap 121 and the positioning block 123, so as to avoid displacement of the magnetic bar 122. When the fine iron filings adsorbed on the magnetic bar 122 are to be treated, the screw cap 121 is unscrewed from the liquid discharge groove 8, and the magnetic bar 122 can be taken out from the liquid discharge groove 8 to treat the fine iron filings.

[0049] The debris can be adhered to the right side wall of the scraper 7 and cannot fall off. In some preferable embodiments, referring to Figure 13 , in order to avoid the debris adhered to the right side wall of the scraper 7 and unable to fall off, the air jet pipe 132 connected to the debris discharge port of the shell 1 is further included. The air inlet end of the air jet pipe 132 is connected with the air pump 131, and the air pump 131 is fixedly installed on the front shell cover 2.

[0050] The air pump 131 works to deliver gas into the air jet pipe 132, and the air jet pipe 132 sprays the gas to the right side wall of the scraper 7 to blow off the debris adhered to the right side wall of the scraper 7, so as to avoid the debris adhered to the right side wall of the scraper 7 and unable to fall off, and further improve the debris treatment effect.

[0051] The above is only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
