Description

Technical Field

[0001] The present invention relates to the technical field of chip discharge of lathes, and specifically relates to a chip discharge device for a numerically controlled lathe with a continuous chip discharge function. Background Art

[0002] Chips are a kind of metal waste generated by cutting metal parts with tools during lathe processing. They are usually in the form of strips and particles, etc. During lathe processing, it is necessary to frequently clean the chips in the waste tray to avoid the poor chip discharge caused by chip accumulation and affect the processing operation.

[0003] Most of the existing numerically controlled lathe chip discharges still rely on manual use of a rake hook to discharge the chips from the lathe. However, the chips usually have sharp edges and are easy to scratch the worker's arm during manual operation. Moreover, the strip-shaped chips generated during the processing of the numerically controlled lathe are easy to collude with other chips in the waste box to form large accumulations, making it necessary for the worker to use a greater force to pull out when using the rake hook, which is very inconvenient to use. Therefore, a chip discharge device for a numerically controlled lathe with a continuous chip discharge function is proposed to solve the above-mentioned problems.

However, the chips usually have sharp edges and are easy to scratch the worker's arm during manual operation.

[0007] (2) Technical Solutions

[0008] The technical solution of the present invention to solve the above technical problems is as follows: A chip discharge device for a numerically controlled lathe with a continuous chip discharge function, including a lathe, a same slide rail is fixedly connected between the front side wall and the rear side wall of the inner cavity of the lathe, a chip discharge mechanism is slidably connected to the outside of the slide rail, the left end of the chip discharge mechanism extends to the left side of the lathe, the front side of the chip discharge mechanism is conductively connected to a transmission device slidably connected to the left side of the lathe, both the front and rear sides of the chip discharge mechanism are fixedly connected with baffles, the opposite sides of the two baffles are both fixedly connected with support plates, the tops of the two support plates are fixedly connected with a same mounting seat, and a shearing mechanism with left and right ends respectively extending to the left and right sides of the mounting seat is provided inside the mounting seat;

[0009] The chip discharge mechanism and the transmission device form a conveyor belt;

[0010] The shearing mechanism includes two fixed toothed plates and two movable toothed plates. The two fixed toothed plates are respectively fixedly connected to the left and right sides of the mounting seat and are symmetrically distributed left and right. The two movable toothed plates are respectively located above the two fixed toothed plates and are slidably connected to the inside of the mounting seat. The two fixed toothed plates are arranged in a staggered manner with the movable toothed plates on the same side. Two slide bars are fixedly connected to the inside of the mounting seat and are symmetrically distributed left and right. U-shaped blocks located inside the mounting seat are fixedly connected to the opposite sides of the two movable toothed plates. Eccentric shafts are slidably connected to the inside of the two U-shaped blocks. Shaft brackets fixedly connected to the bottom wall of the inner cavity of the mounting seat are rotatably connected to the outer sides of the two eccentric shafts. An output device is fixedly connected to the opposite sides of the two eccentric shafts.

[0011] The beneficial effects of the present invention are as follows: When the lathe is processing, the granular iron filings of the strip-shaped iron filings fall naturally by gravity. The strip-shaped iron filings are guided by the mounting seat into the shearing mechanism. The shearing mechanism is driven by the output device to shear the strip-shaped iron filings to make them shorter, and then they fall into the chip removal mechanism together with the granular iron filings. The chip removal mechanism is driven by the transmission device to continuously discharge the iron filings from the lathe.

[0012] The chip removal device of the numerically controlled lathe with the function of continuous chip removal has the advantages of high safety and convenience in use.

[0013] On the basis of the above technical solutions, the present invention can be further improved as follows.

[0014] Further, the lathe is a numerically controlled lathe. A chute is opened on the left side of the lathe. A baffle is fixedly connected to the right side wall of the inner cavity of the lathe and is located above the chip removal mechanism.

[0015] The beneficial effect of adopting the above further solution is that the baffle can prevent the iron filings from falling into the area below the chip removal mechanism through the gap on the right side of the chip removal mechanism.

[0016] Further, the chip removal mechanism includes a fixing plate. The fixing plate is slidably connected to the outer side of the slide rail. Transmission shafts are arranged on the left and right sides of the fixing plate. The same rubber belt piece is drivingly connected to the outer sides of the two transmission shafts. The rubber belt piece is located between the two baffles.

[0017] The beneficial effect of adopting the above further solution is that the rubber belt piece is made of rubber and has strong wear resistance, which can improve the service life of the conveyor belt.

[0018] Further, the transmission device includes a third helical gear and a connecting frame. The third helical gear is fixedly connected to the front surface of the left transmission shaft. The connecting frame is fixedly connected to the inside of the front baffle, and one end passes through the fixed plate and extends below the fixed plate. A bottom of the connecting frame is fixedly connected to an output motor with a right end slidably connected to the left side of the lathe. An output end of the output motor is fixedly connected to a fourth helical gear. Above the fourth helical gear, there is a second gear shaft meshing with the third helical gear. The outside of the second gear shaft is rotatably connected to a shaft fixing frame, and the shaft fixing frame is arranged in an L shape. The bottom of the connecting frame is further fixedly connected to a counterweight block located at the back of the output motor and also slidably connected to the left side of the lathe.

[0019] The beneficial effect of adopting the above further solution is that the counterweight block can prevent the position deviation of the output motor caused by the self - gravity of the output motor.

[0020] Further, the bottom of the lathe is fixedly connected to a base. The base is arranged in a trapezoidal platform shape, and the bottom of the base is fixedly connected to a rubber anti - slip pad.

[0021] The beneficial effect of adopting the above further solution is that rubber has good seismic resistance and can improve the processing stability of the lathe.

[0022] Further, the mounting seat is arranged in a trapezoidal platform shape. A feed platform is further provided on the top of the mounting seat. A tool rest is fixedly connected to the top of the feed platform. The feed platform can provide Y - axis feed for the tool rest. The front - to - back width of the mounting seat is greater than the front - to - back width of the feed platform.

[0023] The beneficial effect of adopting the above further solution is that the mounting seat is arranged in a trapezoidal platform shape, and the inclined surfaces on both sides can better guide longer iron chips into the shearing mechanism to be cut off.

[0024] Further, a transverse movement mechanism is further provided inside the slide rail. The slide rail can provide X - axis feed for the tool rest through the transverse movement mechanism. The left and right sides of the slide rail are arranged in a circular arc shape. The top of the slide rail is fixedly connected to two positioning rails which are symmetrically distributed left and right.

[0025] The beneficial effect of adopting the above further solution is that the positioning rails can reduce the surface pressure exerted by the tool rest on the slide rail and improve the service life of the slide rail.

[0026] Further, the output device includes a biaxial motor, which is fixedly connected to the inside of the mounting seat. Both output ends of the biaxial motor are fixedly connected with first helical gears. Below both of the first helical gears, there is a first gear shaft meshed therewith. On the opposite sides of both of the first gear shafts, there is a second helical gear meshed therewith. On the opposite sides of both of the second helical gears, there is a connecting shaft fixedly connected to the inside of the mounting seat in a rotatable manner. On the opposite sides of both of the connecting shafts, they are respectively fixedly connected to one end of the eccentric shaft on the same side away from the U-shaped block. The upper and lower ends of the second gear shaft and the first gear shaft are both provided with helical gears.

[0027] The beneficial effect of adopting the above further scheme is that the cooperation between the eccentric shaft and the U-shaped block can push the U-shaped block through the eccentric shaft to drive the movable tooth plate to slide back and forth, so that the movable tooth plate cooperates with the fixed tooth plate to cut off longer iron filings.

[0057] Working principle:

[0058] The first step: When the lathe 1 is processing, the granular iron filings of the strip-shaped iron filings naturally fall by gravity. The strip-shaped iron filings are guided by the trapezoidal inclined plane of the mounting seat 7 into the shearing mechanism 8. At this time, the double-shaft motor 901 is driven by the first bevel gear 902 to drive the first gear shaft 903 to transmit power. The first gear shaft 903 drives the second bevel gear 904 to drive the eccentric shaft 805 to rotate within the shaft frame 806. When the eccentric shaft 805 rotates, due to its eccentric characteristic, it pushes the U-shaped block 804 to move back and forth, so that the U-shaped block 804 drives the movable tooth plate 802 to slide back and forth, forming a shearing motion with the fixed tooth plate 801 to shear the strip-shaped iron filings and make them shorter, and then they fall onto the rubber belt sheet 303 together with the granular iron filings;

[0059] The second step: Start the output motor 403. The output motor 403 is driven by the fourth bevel gear 404 to drive the second gear shaft 405 to rotate within the shaft fixing frame 406, thereby driving the third bevel gear 401 to rotate. At this time, the third bevel gear 401 drives the left transmission shaft 302 to rotate, and the left transmission shaft 302 is driven by the rubber belt sheet 303 to drive the right transmission shaft 302 to rotate, so that the rubber belt sheet 303 can continuously discharge the iron filings outside the lathe 1;

[0060] During use, the tool rest 13 can move along the Y-axis by the feed platform 12, and at the same time, the tool rest 13 can also move along the X-axis by the slide rail 2. When the tool rest 13 moves along the X-axis, the fixing plate 301 is driven by the mounting seat 7, the support plate 6 and the baffle 5 to move synchronously with the tool rest 13 outside the slide rail 2, and the baffle 5 can keep the falling iron filings on the rubber belt sheet 303 so that they will not fall below the chip removal mechanism 3.

[0061] It should be noted that in the text of the present invention, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
