Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, in particular to an upper extrusion roller for a machine tool chip removal and extrusion integrated machine. Background Art

[0002] During the machining process, CNC machine tools will generate a large amount of chips. Different metal materials will generate chips of various shapes during the machining process. When the material to be processed is various steel materials, the chips generated during the machining process are mainly in the form of balls, rolls, and strips. The balls, rolls, and strips of chips are very fluffy in the natural accumulation state. Therefore, the volume of chip accumulation is large, which brings great trouble to cleaning the chips. It is often necessary to transport them out many times, which affects production efficiency. Therefore, it is necessary to squeeze the chips to reduce the volume of the chips. Since the chips are in the form of strips, if the roller with roller claws is used to transport and squeeze the strip chips, the strip chips are easy to entangle with the roller claws. If the strip chips wrapped around the roller claws are not cleaned in time, the strip chips on the roller body will become more and more entangled, which will affect the rotation of the roller body and the extrusion efficiency of the cutting. If the rotation of the roller body is stopped regularly to clean the roller body, the efficiency of extruding the chips will be reduced. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the problem in the prior art that when a roller body with roller claws is used to transport and extrude strip-shaped chips, the strip-shaped chips are easily entangled on the roller claws, which affects both the rotation of the roller body and the cutting extrusion efficiency, an extrusion roller is provided for a machine tool chip removal and extrusion machine.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an upper extrusion roller for a chip removal and extrusion integrated machine for a machine tool comprises an inner rotating shaft, the inner rotating shaft is fixedly mounted on the machine casing, a front roller body, a middle roller body and a rear roller body are rotatably mounted on the inner rotating shaft, the front roller body and the rear roller body are both coaxially fixedly mounted with an outer rotating shaft, the two outer rotating shafts are rotatably mounted on the machine casing, a rear end surface of the front roller body, a front and rear end surface of the middle roller body, and a front end surface of the rear roller body are coaxially provided with a receiving groove, an even number of limiting openings connected with the receiving groove are evenly provided on the outer circumferential surfaces of the front roller body, the middle roller body and the rear roller body, the middle roller body has a plurality of front roller bodies, a plurality of middle roller bodies, and a rear roller body are sequentially fitted from front to back, after the front roller body is fitted with an adjacent middle roller body, after the two adjacent middle roller bodies are fitted with each other, after the rear roller body is fitted with the adjacent middle roller body, the two opposite receiving grooves are assembled into an accommodating cavity, and the two opposite limiting openings are assembled into a limiting through hole, A flip push rod is slidably inserted in the limiting through hole, the radius of the flip push rod is equal to the radius of the limiting through hole, and an elastic element is arranged on the outer sleeve of the flip push rod, one end of the elastic element is fixedly connected to the flip push rod, and the other end is fixedly connected to the inner wall of the accommodating cavity, and a cam is fixedly installed on the inner rotating shaft, and the plurality of cams are respectively located in the plurality of accommodating cavities, and the inner ends of the flip push rods in the plurality of limiting through holes connected to the same accommodating cavity are all in contact with the outer circumferential surface of the cam; when the flip push rods in the two upper extrusion rollers are arranged relatively to each other, the length of the flip push rod extending out of the limiting through hole is the longest, which is the longest flip push rod; on the same upper extrusion roller, the flip push rod directly opposite to the longest flip push rod is the shortest flip push rod, and the shortest flip push rod is completely accommodated in the limiting through hole, and during the rotation of the upper extrusion roller, the plurality of flip push rods on the same circumference gradually change from the longest flip push rod to the shortest flip push rod, and then gradually change from the shortest flip push rod to the longest flip push rod. The upper extrusion roller of the chip removal and extrusion integrated machine of the machine tool of the present invention, when in use, if strip chips are wound on the flip push rod, during the rotation of the front roller body, the middle roller body and the rear roller body, the cam does not rotate, and the flip push rods on the front roller body, the middle roller body and the rear roller body rotate around the central axis of the front roller body. During the rotation, the flip push rod is always in contact with the outer peripheral surface of the cam, and the flip push rod gradually changes from the longest flip push rod to the shortest flip push rod, and the flip push rod gradually retracts into the guide hole. Since the radius of the guide hole is equal to the radius of the flip push rod, when the flip push rod is retracted into the guide hole, the outer peripheral surfaces of the front roller body, the middle roller body and the rear roller body scrape the strip chips from the flip push rod, and the upper extrusion roller cleans the strip chips on the flip push rod once every rotation of the upper extrusion roller, thereby realizing timely cleaning of the strip chips wound on the flip push rod, which can effectively prevent the strip chips on the upper extrusion roller from becoming more and more entangled, ensure the normal rotation of the upper extrusion roller, and improve the extrusion efficiency of the upper extrusion roller for chips.

[0005] In order to be able to replace the front roller body, the middle roller body and the rear roller body separately, the front roller body and the middle roller body, the two adjacent middle roller bodies, and the middle roller body and the rear roller body cannot be connected in a fixed manner. Under the premise of not adopting a fixed manner, it is necessary to ensure that the front roller body, the middle roller body and the rear roller body rotate coaxially and synchronously. Therefore, a connecting rod is vertically fixedly installed on the rear end face of the front roller body, and several of the connecting rods are evenly distributed along the circumference of the central axis of the front roller body. Several of the middle roller bodies are provided with connecting through holes, and several of the connecting through holes are arranged in one-to-one correspondence with several connecting rods. A connecting blind hole is opened on the front end face of the rear roller body, and several of the connecting blind holes are arranged in one-to-one correspondence with several connecting rods. The connecting rods pass through several connecting through holes in turn and are inserted into the connecting blind holes.

[0006] In order to reduce the friction between the flip push rod and the cam and also to facilitate the flip push rod to insert into the chip mass, both ends of the flip push rod are spherical surfaces.

[0007] In order to better fix the cam, the height of the cam is equal to the height of the accommodating cavity.

[0008] Preferably, the elastic element is a compression spring.

[0009] The beneficial effect of the present invention is that the upper extrusion roller of the machine tool chip removal and extrusion integrated machine of the present invention is used. When in use, if strip chips are wound on the flip push rod, during the rotation of the front roller body, the middle roller body and the rear roller body, the cam does not rotate, and the flip push rods on the front roller body, the middle roller body and the rear roller body rotate around the central axis of the front roller body. During the rotation, the flip push rod is always in contact with the outer peripheral surface of the cam, and the flip push rod gradually changes from the longest flip push rod to the shortest flip push rod, and the flip push rod gradually retracts into the guide hole. Since the radius of the guide hole is equal to the radius of the flip push rod, when the flip push rod is retracted into the guide hole, the outer peripheral surfaces of the front roller body, the middle roller body and the rear roller body scrape the strip chips off the flip push rod, and the upper extrusion roller cleans the strip chips on the flip push rod once every rotation of the upper extrusion roller, thereby realizing timely cleaning of the strip chips wound on the flip push rod, which can effectively prevent the strip chips on the upper extrusion roller from becoming more and more entangled, ensure the normal rotation of the upper extrusion roller, and improve the extrusion efficiency of the upper extrusion roller for chips.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] like Figure 1-Figure 5 The upper extrusion roller of a chip removal and extrusion integrated machine shown in the figure has an inner rotating shaft 4-2, which is fixedly mounted on the machine casing, and a front roller body 4-3, a middle roller body 4-4 and a rear roller body 4-5 are rotatably mounted on the inner rotating shaft 4-2, and an outer rotating shaft 4-6 is coaxially fixedly mounted on the front roller body 4-3 and the rear roller body 4-5, and the two outer rotating shafts 4-6 are rotatably mounted on the machine casing, and a receiving groove 4-7 is coaxially opened on the rear end surface of the front roller body 4-3, the front and rear end surfaces of the middle roller body 4-4, and the front end surface of the rear roller body 4-5, and an even number of grooves are uniformly opened on the outer circumference of the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5. The middle roller body 4-4 has multiple limiting openings 4-8 connected to the accommodating groove 4-7. The front roller body 4-3, multiple middle roller bodies 4-4, and the rear roller body 4-5 are sequentially fitted from front to back. After the front roller body 4-3 is fitted with the adjacent middle roller body 4-4, after the two adjacent middle roller bodies 4-4 are fitted, and after the rear roller body 4-5 is fitted with the adjacent middle roller body 4-4, the two opposite accommodating grooves 4-7 are assembled into an accommodating cavity, and the two opposite limiting openings 4-8 are assembled into a limiting through hole. A flip push rod 4-1 is slidably inserted in the limiting through hole. The radius of the flip push rod 4-1 is equal to the radius of the limiting through hole, and both ends of the flip push rod 4-1 are spherical surfaces.

[0019] The outer cover of the flip push rod 4-1 is provided with an elastic element 4-9, which is a compression spring. One end of the elastic element 4-9 is fixedly connected to the flip push rod 4-1, and the other end is fixedly connected to the inner wall of the accommodating cavity. A cam 4-10 is fixedly installed on the inner shaft 4-2, and the height of the cam 4-10 is equal to the height of the accommodating cavity. A plurality of cams 4-10 are respectively located in a plurality of accommodating chambers, and the inner ends of the flip push rods 4-1 in a plurality of limiting through holes connected to the same accommodating chamber are all in contact with the outer circumference of the cam 4-10; when the flip push rods 4-1 in the two upper extrusion rollers are arranged opposite to each other, the flip push rod 4-1 extends out of the limiting through hole for the longest length, which is the longest flip push rod 4-1; on the same upper extrusion roller, the flip push rod 4-1 directly opposite to the longest flip push rod 4-1 is the shortest flip push rod 4-1, and the shortest flip push rod 4-1 is completely received in the limiting through hole. During the rotation of the upper extrusion roller, a plurality of flip push rods 4-1 on the same circumference gradually change from the longest flip push rod 4-1 to the shortest flip push rod 4-1, and then gradually change from the shortest flip push rod 4-1 to the longest flip push rod 4-1.

[0020] In order to be able to replace the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 separately, the front roller body 4-3 and the middle roller body 4-4, the two adjacent middle roller bodies 4-4, and the middle roller body 4-4 and the rear roller body 4-5 cannot be connected in a fixed manner. Under the premise of not adopting a fixed manner, it is necessary to ensure that the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 rotate coaxially and synchronously. Therefore, a connecting rod 4-11 is vertically fixedly installed on the rear end face of the front roller body 4-3, and several connecting rods 4-11 are evenly distributed along the circumference of the central axis of the front roller body 4-3. Several middle roller bodies 4-4 are provided with connecting through holes, and several connecting through holes are arranged one-to-one with several connecting rods 4-11. A connecting blind hole is opened on the front end face of the rear roller body 4-5, and several connecting blind holes are arranged one-to-one with several connecting rods 4-11. The connecting rod 4-11 passes through several connecting through holes in turn and is inserted into the connecting blind hole.

[0021] The chip removal and extrusion integrated machine of the present invention uses an extrusion roller. When in use, if strip chips are wound around the flip push rod 4-1, during the rotation of the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5, the cam 4-10 does not rotate, and the flip push rods 4-1 on the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 rotate around the central axis of the front roller body 4-3. During the rotation, the flip push rod 4-1 is always in contact with the outer peripheral surface of the cam 4-10, and the flip push rod 4-1 gradually changes from the longest flip push rod 4-1 to the shortest flip push rod 4-1. The turning push rod 4-1 is retracted into the guide hole. Since the radius of the guide hole is equal to the radius of the turning push rod 4-1, when the turning push rod 4-1 is retracted into the guide hole, the outer circumferential surfaces of the front roller body 4-3, the middle roller body 4-4 and the rear roller body 4-5 scrape the strip chips off the turning push rod 4-1. The strip chips on the turning push rod 4-1 are cleaned once the upper extrusion roller rotates one circle, thereby realizing timely cleaning of the strip chips entangled on the turning push rod 4-1, which can effectively prevent the strip chips on the upper extrusion roller from becoming more and more entangled, ensure the normal rotation of the upper extrusion roller, and improve the extrusion efficiency of the upper extrusion roller for chips.
