Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, in particular to a cutting device for machining valve tappets. Background Art

[0002] The valve tappet is an important component in the automobile engine. It belongs to the valve transmission group of the valve mechanism and is the follower of the cam. In the processing of the valve tappet, cutting the copper tube is a key step. After the copper tube is cut into an appropriate length, it can be used as the central support column of the valve tappet through further processing. In some cases, it is necessary to cut a complete copper tube into multiple copper tubes of equal length to meet the required length of the valve tappet center support column.

[0003] The patent with announcement number CN111531592B discloses a cutting device, and in particular, relates to a PPR pipe uniform cutting device. The technical problem to be solved is to design a PPR pipe uniform cutting device that is simple to operate, can effectively save manpower, and can save time consumed during work, thereby improving work efficiency. The PPR pipe uniform cutting device includes a base, on which a frame is connected, and the upper parts of both sides of the frame are connected to fixed blocks, and the bottom of the fixed block is connected to a guide rod; a cutter, which is slidably connected between the guide rods on both sides, and a first return spring is connected between the cutter and the guide rod; a knife seat, which is connected to the lower part of the frame, and the knife seat is located below the cutter. The patent can drive the cutter to cut the PPR pipe through a power mechanism, thereby achieving the effect of cutting the PPR pipe.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] A collection frame is set up to collect multiple cut pipes. However, when the pipes fall into the collection frame, they are rather messy. Generally, staff are required to count the number of pipes to ensure that they match the actual required number. The messily placed pipes will increase the difficulty for staff to count the number of pipes and are easy to confuse. In addition, in some cases, staff are required to check the appearance quality of the cut pipes to observe whether there are defects such as burrs and cracks on the pipe cross section. This operation directly affects the subsequent processing quality of the pipes. The messily placed pipes are not conducive to the inspection operation of the staff, and are prone to missed inspections, which in turn affects the subsequent processing of the pipes.

[0006] To this end, the present invention provides a cutting device for valve tappet machining. Summary of the invention

[0047] Specifically, the valve tappet is an important component in an automobile engine, belongs to the valve transmission group of the valve mechanism, and is a follower of the cam. In the processing of the valve tappet, cutting the copper tube is a key step. After the copper tube is cut into an appropriate length, it can be used as a central support column of the valve tappet through further processing. In some cases, it is necessary to cut a complete copper tube into multiple copper tubes of equal length to meet the required length of the central support column of the valve tappet. When the existing pipe cutting device is used, a collection frame is usually set at the drop position of the cut pipe to collect multiple pipes. However, when the pipes fall into the collection frame, they are messy. In general, the staff needs to count the number of pipes to ensure that they match the actual number of pipes required. The messy pipes will increase the difficulty of the staff to count the number of pipes and are easy to confuse. In addition, in some cases, the staff is required to check the appearance quality of the cut pipes to observe whether there are defects such as burrs and cracks on the pipe section. This operation directly affects the subsequent processing quality of the pipes. The messy pipes are not conducive to the inspection operation of the staff, and it is easy to miss the inspection, which in turn affects the subsequent processing of the pipes.

[0048] Therefore, in order to solve the above problems, when the present embodiment is in use, after the copper tube is fixed, according to the length of the copper tube to be cut, the motor 16 is used to drive the fixing plate 41 to move from right to left, so that the position of the copper tube to be cut is below the blade 17, and the copper tube sleeve is set at the limit rod 16 at this time, and the limit rod 16 does not contact the inner wall of the copper tube, and then the hydraulic cylinder 3 is used to drive the blade 17 to descend, and at the same time, the motor 3 18 is used to drive the blade 17 to rotate, so that the copper tube can be cut, and the cut copper tube will fall on the limit rod 16, and then the motor 5 22 The adjusting plate 21 is driven to rotate, and the limit rod 16 is tilted, so that the cut copper tube slides along the limit rod 16 to the adjusting disk 25, and then the limit rod 16 is driven to restore the horizontal level again, and then the copper tube continues to be transported to the left, and the above-mentioned cutting operation is repeated, so that multiple copper tubes can be placed horizontally on the limit rod 16 in a mutually fitting manner. When a certain amount of copper tubes are placed on the limit rod 16, the staff only needs to count the number of copper tubes from left to right, which is more orderly and not easy to be confused. In addition, when the staff conducts an appearance quality inspection on the copper tube, it is not easy to miss the inspection.

[0049] When the staff inspects the appearance quality of the copper tubes, it is inconvenient to observe the cross section of the copper tubes because the copper tubes fit each other. Therefore, the limit rod 16 can be driven to rotate counterclockwise to tilt the limit rod 16. At this time, the multiple copper tubes fit closely under the action of gravity, and then the motor 4 20 is used to drive the threaded rod 3 13 to rotate, so that the displacement block 32 slides on the slide rod 3 12, and the displacement block 32 moves horizontally until the bottom of the partition 1 33 is aligned with the gap between the two leftmost copper tubes, and then the motor 4 20 is used to drive the threaded rod 3 13 to rotate, so that the displacement block 32 slides on the slide rod 3 12, and the displacement block 32 moves horizontally until the bottom of the partition 1 33 is aligned with the gap between the two leftmost copper tubes. Motor eight 39 drives threaded rod four 40 to rotate, so that partition three 35 slides. When partition three 35 slides, with the cooperation of connecting rod two 36, connecting rod three 37 and connecting rod four 38, the spacing between partition one 33, partition two 34 and partition three 35 changes, and the change distance is the same. Since the copper tubes are of equal length, the bottoms of partition one 33, partition two 34 and partition three 35 will align with the gap between two adjacent copper tubes. Then, motor two 8 drives threaded rod two 9 to rotate, so that lifting plate 10 moves down. The first copper tube 33 is moved downwards, so that the partition 33, the second copper tube 34 and the third copper tube 35 are inserted into the gap between two adjacent copper tubes. At this time, the spacing between the first copper tube 33, the second copper tube 34 and the third copper tube 35 continues to increase, so that multiple copper tubes can be pushed at the same time to generate spacing between adjacent copper tubes, and then the first copper tube 33, the second copper tube 34 and the third copper tube 35 are driven to move away from the gap, and then the motor 7 29 is used to drive the triangular block 26 to rotate, so that the multiple connecting rods 1 28 are rotated at the same time, so that the multiple sliders 27 are moved radially at the same time, until the multiple limit rods 16 are all in contact with the inner wall of the copper tube. At this time, the multiple copper tubes are fixed. At this time, the staff can check the appearance quality of the copper tube again, and the cross section of the copper tube can be observed, which ensures the comprehensiveness of the inspection. In addition, the motor 6 23 can be used to drive the rotating plate 24 to rotate at the same time, so that the multiple copper tubes on the limit rod 16 rotate at the same time, so that each position of the copper tube faces the staff, without the need for the staff to frequently move their bodies, thereby reducing the labor intensity of the staff in performing appearance quality inspection.

[0050] When the copper tube on the limiting rod 16 needs to be collected, it is only necessary to drive the limiting rod 16 away from the inner wall of the copper tube, and then drive the limiting rod 16 to rotate clockwise to make the copper tube slide down, and then use a container to collect the copper tube;

[0051] Therefore, by utilizing the partition rotary horizontal placement mechanism, the cut copper tube can slide along the limit rod 16 to the adjustment disk 25, so that multiple copper tubes can be placed horizontally on the limit rod 16 in a mutually fitting manner. After a certain amount of copper tubes are placed on the limit rod 16, the staff only needs to count the number of copper tubes from left to right, which is more orderly and not easy to be confused. In addition, when the staff conducts an appearance quality inspection on the copper tubes, it is not easy to miss the inspection. In addition, the partition 1 33, the partition 2 34, and the partition 3 35 can be inserted into the two adjacent partitions on the limit rod 16. The gaps between the copper tubes are located at the same time, and the plurality of copper tubes are pushed at the same time to make the same spacing between adjacent copper tubes. Then, the limiting rod 16 is used to fix the copper tubes. At this time, the staff can inspect the appearance quality of the copper tubes and observe the cross-section of the copper tubes, thereby ensuring the comprehensiveness of the inspection. In addition, the motor 6 23 can be used to drive the rotating plate 24 to rotate, so that the plurality of copper tubes on the limiting rod 16 rotate at the same time, so that each position of the copper tubes faces the staff, without the need for the staff to frequently move their bodies, thereby reducing the labor intensity of the staff in performing appearance quality inspection.

[0052] Working principle: place the right end of the copper tube to be cut between multiple clamping blocks 42, and the right end face of the copper tube is fitted with the left end face of the fixing plate 41, then manually rotate the threaded rod 5 43 to drive the threaded block 44 to move, so that multiple connecting rods 5 45 simultaneously drive multiple adjusting rods 31 to move radially until the clamping block 42 contacts the outer wall of the copper tube, so that the copper tube can be fixed, so that steel tubes of different diameters can be clamped and fixed, thereby ensuring the stability during the cutting process. When the copper tube is fixed, according to the length of the copper tube to be cut, the motor 6 is used to drive the fixing plate 41 to move from right to left, so that the position of the copper tube to be cut is under the blade 17, and at this time, the copper tube sleeve is set at the limit rod 16, and the limit rod 16 does not contact the inner wall of the copper tube, and then the hydraulic cylinder 3 is used to drive the fixing plate 41 to move from right to left. The movable blade 17 descends, and at the same time, the motor 3 18 is used to drive the blade 17 to rotate, so that the copper tube can be cut, and the cut copper tube will fall on the limit rod 16, and then the motor 5 22 is used to drive the adjustment plate 21 to rotate, so that the limit rod 16 is tilted, so that the cut copper tube will slide along the limit rod 16 to the adjustment disk 25, and then the limit rod 16 is driven again to restore the horizontal level, and then the copper tube continues to be transported to the left, and the above-mentioned cutting operation is repeated, so that multiple sections of copper tubes can be placed horizontally on the limit rod 16 in a mutually fitting manner. When a certain amount of copper tubes are placed on the limit rod 16, the staff only needs to count the number of copper tubes from left to right, which is more orderly and not easy to be confused. In addition, when the staff conducts appearance quality inspection on the copper tubes, it is not easy to miss the inspection;When the staff inspects the appearance quality of the copper tubes, it is inconvenient to observe the cross section of the copper tubes because the copper tubes fit each other. Therefore, the limit rod 16 can be driven to rotate counterclockwise to tilt the limit rod 16. At this time, the multiple copper tubes fit closely under the action of gravity, and then the motor 4 20 is used to drive the threaded rod 3 13 to rotate, so that the displacement block 32 slides on the slide rod 3 12, and the displacement block 32 moves horizontally until the bottom of the partition 1 33 is aligned with the gap between the two leftmost copper tubes, and then the motor 8 39 is used to drive the threaded rod 4 40 to rotate, so that the partition The third partition plate 35 slides. When the third partition plate 35 slides, with the cooperation of the second connecting rod 36, the third connecting rod 37 and the fourth connecting rod 38, the spacing between the first partition plate 33, the second partition plate 34 and the third partition plate 35 changes, and the change distance is the same. Since the copper tubes are of equal length, the bottoms of the first partition plate 33, the second partition plate 34 and the third partition plate 35 will be aligned with the gap between the two adjacent copper tubes. Then, the second motor 8 drives the threaded rod 29 to rotate, so that the lifting plate 10 is lowered, and the first partition plate 33, the second partition plate 34 and the third partition plate 35 are inserted into the gap between the two adjacent copper tubes. When the spacing between the partition 1 33, the partition 2 34 and the partition 3 35 continues to increase, the multiple copper tubes can be pushed at the same time to generate spacing between adjacent copper tubes, and then the partition 1 33, the partition 2 34 and the partition 3 35 are driven to move away from the gap, and then the motor 7 29 is used to drive the triangular block 26 to rotate, so that the multiple connecting rods 1 28 rotate at the same time, so that the multiple sliders 27 move radially at the same time, until the multiple limit rods 16 are all in contact with the inner wall of the copper tube. At this time, the multiple copper tubes are fixed. At this time, the staff will check the appearance quality of the copper tubes again, that is, The cross section of the copper tube can be observed, which ensures the comprehensiveness of the inspection. In addition, the motor 6 23 can be used to drive the rotating plate 24 to rotate, so that the multiple copper tubes on the limit rod 16 rotate at the same time, so that the various positions of the copper tubes face the staff, and the staff does not need to move their bodies frequently, which reduces the labor intensity of the staff in the appearance quality inspection. When the copper tubes on the limit rod 16 need to be collected, it is only necessary to drive the limit rod 16 away from the inner wall of the copper tube, and then drive the limit rod 16 to rotate clockwise to make the copper tube slide off, and then use the container to collect the copper tube.Therefore, by utilizing the partition rotary horizontal placement mechanism, the cut copper tube can slide along the limit rod 16 to the adjustment disk 25, so that multiple copper tubes can be placed horizontally on the limit rod 16 in a mutually fitting manner. After a certain amount of copper tubes are placed on the limit rod 16, the staff only needs to count the number of copper tubes from left to right, which is more orderly and not easy to be confused. In addition, when the staff conducts an appearance quality inspection on the copper tubes, it is not easy to miss the inspection. In addition, the partition 1 33, the partition 2 34, and the partition 3 35 can be inserted into the two adjacent partitions on the limit rod 16. The gaps between the copper tubes are located at the same time, and multiple copper tubes are pushed at the same time to make the same spacing between adjacent copper tubes, and then the copper tubes are fixed by the limit rod 16. At this time, the staff can inspect the appearance quality of the copper tubes and observe the cross section of the copper tubes, ensuring the comprehensiveness of the inspection. In addition, the motor 6 23 can be used to drive the rotating plate 24 to rotate, so that multiple copper tubes on the limit rod 16 rotate at the same time, so that each position of the copper tube faces the staff, without the need for the staff to frequently move their bodies, reducing the labor intensity of the staff in the appearance quality inspection. ;
