Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a chip removal structure of a numerically controlled machine tool for a metal workpiece. Background Art

[0002] The existing lathe chip removal structure is large in size, inconvenient to move, and has a small receiving area. The chips are easily scattered on the ground outside. When the waste box is full, the staff cannot find it in time, which may cause the chips to overflow, causing unnecessary work for the staff. In addition, the waste box is not easy to disassemble, and it is not convenient to clean the waste.

[0003] To solve the above problem, there is a solution for the chip removal structure of a CNC lathe (Announcement No. CN213858330U). Through a waste box, a buzzer, and a gravity sensor, when too much debris is collected in the waste box, the gravity sensor measures that the weight of the debris inside the waste box exceeds a preset value, and the buzzer will sound an alarm to remind the staff that the debris in the waste box needs to be cleaned.

[0004] However, there are the following deficiencies in judging the amount of debris inside the waste bin by using a gravity sensor: when the cut debris is in the shape of coiled strips, the debris in the waste bin is in a fluffy state and is relatively light in weight. When the debris falls out of the waste bin, the weight does not reach the threshold of the gravity sensor. After the waste bin is full, it needs to be emptied manually, and the chip removal process needs to be suspended at this time. When the chip removal amount is large, the debris is prone to accumulation. Utility Model Content

[0005] The utility model aims to provide a chip removal structure for a metal workpiece CNC machine tool to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a chip removal structure of a metal workpiece CNC machine tool, comprising a support frame, a driving roller is installed inside the support frame, a conveyor belt is installed on the driving roller, and a discharge pipe is installed at the right end of the conveyor belt;

[0007] The conveyor belt is placed under the chip discharge port of the CNC machine tool. When the conveyor belt is driven by the driving roller to rotate, the metal chips can be transported to the inside of the discharge pipe, and the metal chips can fall into the inside of the barrel;

[0008] A support plate is rotatably connected to a carrying plate, and a placement groove and a stopper are provided on the surface of the carrying plate. A plurality of barrels are placed on the carrying plate. The carrying plate rotates to drive the barrels to move to the bottom of the discharge pipe. When the barrels are full, the carrying plate drives the empty barrels to move to the bottom of the discharge pipe, so that metal chips can be continuously received;

[0009] An infrared distance measuring sensor is installed on the surface of the discharge pipe and is located above the barrel. The infrared distance measuring sensor detects the amount of debris stored in the barrel. When the barrel is almost full of metal chips, the barrel can be switched in time.

[0010] Furthermore, a guide plate is installed on the edge of the support frame surface. When metal chips fall onto the guide plate, they slide along the guide plate to the conveyor belt. The surface of the conveyor belt is provided with a plurality of anti-slip strips, which can prevent the metal chips from sliding downward when the metal chips are transported upward.

[0011] Furthermore, a gear ring is provided on the surface of the carrier plate, a transmission is installed on the surface of the support plate, a motor is installed on the input end of the transmission, and the output teeth of the transmission are engaged with the gear ring. The transmission can increase the output torque of the motor, ensuring that the motor can smoothly drive the carrier plate to rotate and realize automatic switching of the barrel.

[0012] Furthermore, a handle is provided on the upper part of the barrel surface, and a roller is provided on the lower part of the barrel surface. The handle and the roller are used to facilitate the movement of the barrel, and the transfer of metal chips is more labor-saving.

[0013] Furthermore, a guide rail is installed on the surface of the discharge pipe, and a slide seat is slidably connected to the surface of the guide rail. The infrared ranging sensor is connected to the slide seat. An adjustment bolt is screwed on the surface of the slide seat to resist the guide rail. The height of the infrared ranging sensor can be adjusted, thereby controlling the amount of metal chips collected in the barrel.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The metal chips generated by CNC machine processing products are transported by conveyor belts. The left and right guide plates expand the collection range. Some of the splashed metal chips will be collected by the guide plates, improving the problem of metal chips falling to the ground.

[0016] (2) The metal chips are sent to the discharge pipe through the conveyor belt. The discharge pipe guides the metal chips to fall into the material barrel and are collected. The amount of metal chips stored in the material barrel is detected by the infrared distance sensor. When the height of the metal chips and the distance from the infrared distance sensor reach the threshold, the empty material barrel is switched to prevent the metal chips from overflowing from the material barrel.

[0017] (3) The motor controls the rotation of the carrier plate, and the infrared distance sensor is linked to the motor. When the barrel needs to be switched, the motor controls the barrel to switch automatically. The metal chip discharge process only needs to be stopped briefly, which is also convenient for the staff to empty the barrel.

[0018] (4) The material barrel is clamped by the placement groove on the carrying plate to ensure that the material barrel will not move freely. The material barrel can be easily moved under the action of the roller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] See also Figure 1-4 The utility model provides a technical solution: a chip removal structure of a metal workpiece CNC machine tool, comprising a support frame 1, a driving roller 21 is installed inside the support frame 1, a conveyor belt 22 is installed on the driving roller 21, and a discharge pipe 6 is installed at the right end of the conveyor belt 22;

[0026] The conveyor belt 22 is a metal conveyor belt 22, which ensures that the conveyor belt 22 is more wear-resistant and not easily damaged during use. The left part of the conveyor belt 22 is horizontally arranged, and the right part of the conveyor belt 22 is tilted upward, so that the metal chips are sent to a high place and can fall smoothly into the inside of the bucket 11;

[0027] A support plate 17 is rotatably connected to a carrier plate 9, and a placement groove 18 and a stopper 10 are provided on the surface of the carrier plate 9. A plurality of barrels 11 are placed on the carrier plate 9. The carrier plate 9 rotates to drive the barrels 11 to move below the discharge pipe 6. The placement groove 18 is inclined toward the center of the carrier plate 9, so that the barrels 11 are in a slightly tilted state. During the rotation of the carrier plate 9, the barrels 11 are prevented from falling off the carrier plate 9. The stopper 10 can prevent the slightly tilted barrels 11 from tilting, thereby improving the stability of the barrels 11 placed on the carrier plate 9;

[0028] The infrared distance sensor 8 is installed on the surface of the discharge pipe 6 and is located above the barrel 11. The infrared distance sensor 8 detects the amount of debris stored in the barrel 11, and the barrel 11 can be switched in time before it is full.

[0029] In this embodiment, if Figure 2 As shown, a guide plate 2 is installed on the edge of the surface of the support frame 1. The guide plate 2 is inclined and opened to the left and right sides to expand the collection range of metal chips. A plurality of anti-slip strips 23 are provided on the surface of the conveyor belt 22. There are collecting grooves between adjacent anti-slip strips 23. Metal chips can be contained in the collecting grooves to prevent them from sliding down when they are transported obliquely upward.

[0030] In this embodiment, if Figure 2 As shown, a screw plate 3 is fixedly connected to the side of the support frame 1, and a support leg 4 is screwed inside the screw plate 3. The height can be adjusted by twisting the support leg 4. When the ground is uneven, the position of the support leg 4 can be adjusted to make the support frame 1 in a flat state.

[0031] In this embodiment, if Figure 2 As shown, a reinforcing column 5 is provided on the upper surface of the support plate 17, and the upper end of the reinforcing column 5 is connected to the support frame 1 to reinforce the support frame 1 and ensure the stability of the support frame 1 in a tilted state.

[0032] In this embodiment, if Figure 3 As shown, a gear ring 24 is provided on the surface of the carrier plate 9, a transmission 16 is installed on the surface of the support plate 17, a motor 15 is installed on the input end of the transmission 16, and the output teeth of the transmission 16 are meshed with the gear ring 24. The motor 15 can increase the torque after being decelerated by the transmission 16, thereby driving the gear ring 24 and the carrier plate 9 to rotate stably and smoothly.

[0033] In this embodiment, if Figure 1 As shown, a handle 13 is provided on the upper surface of the barrel 11, and a roller 12 is provided on the lower surface of the barrel 11. The handle 13 can be used to pull the barrel 11 to move under the action of the roller 12, which is more convenient when emptying the metal chips inside the barrel 11.

[0034] In this embodiment, if Figure 1 As shown, a slope plate 14 is provided on the right side of the support plate 17 , and when the material barrel 11 is pulled through the slope plate 14 , it is convenient to move the material barrel 11 onto the carrying plate 9 .

[0035] In this embodiment, if Figure 4 As shown, a guide rail 7 is installed on the surface of the discharge pipe 6, and a slide seat 19 is slidably connected to the surface of the guide rail 7. The infrared ranging sensor 8 is connected to the slide seat 19, and an adjusting bolt 20 is screwed on the surface of the slide seat 19 to resist the guide rail 7. When the adjusting bolt 20 is loosened, the height of the slide seat 19 on the guide rail 7 can be adjusted, and then the distance between the infrared ranging sensor 8 and the barrel 11 can be adjusted to ensure that the metal chips in the barrel 11 will not overflow.

[0036] Specifically, when in use, the guide plate 2 is placed under the chip discharge port of the machine tool, and the conveyor belt 22 sends the metal chips generated by the machine tool processing parts to the discharge pipe 6. The discharge pipe 6 guides the metal chips to fall into the barrel 11. The infrared ranging sensor 8 monitors the accumulation height of the metal chips in the barrel 11 in real time. When the accumulation height of the metal chips and the distance from the infrared ranging sensor 8 reach a preset threshold, the motor 15 starts working. The motor 15 drives the gear ring 24 to rotate through the transmission 16. The gear ring 24 drives the carrier plate 9 and the barrel 11 on the carrier plate 9 to rotate, so that the empty barrel 11 moves to the bottom of the discharge pipe 6. The motor 15 stops working. Multiple barrels 11 can be placed on the carrier plate 9, and metal chips can be continuously received, which also reserves time for emptying the barrel 11.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
