Description

Technical Field

[0001] The utility model belongs to the technical field of piston ring processing equipment, and more specifically, particularly relates to an automatic chamfering machine for processing the outer edge of a piston ring. Background Art

[0002] A piston ring is a metal ring used to be embedded inside a piston groove. Piston rings are divided into two types: compression rings and oil rings. Compression rings can be used to seal the combustible mixture inside the combustion chamber, and oil rings are used to scrape off the excess oil on the cylinder. A piston ring is a metal elastic ring with a large outward expansion deformation. It is assembled into the corresponding annular groove of its cross-section. The reciprocating and rotating piston ring forms a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove by relying on the pressure difference of gas or liquid.

[0003] When chamfering the outer edge of the existing piston ring, the chamfering method mostly relies on manual operation of the machine tool for grinding. Although the chamfering and grinding effect is good, the manual operation has a large labor intensity. The employee not only needs to fix the piston rings one by one on the clamping mechanism of the machine tool, but also needs to frequently operate the grinding tool for manual chamfering, and there will be a slight deviation in the chamfering size. As a result, when it is put into use, there will be situations such as air leakage in the cylinder or mutual wear between the cylinder and the piston ring.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic chamfering machine for processing the outer edge of a piston ring is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an automatic chamfering machine for processing the outer edge of a piston ring to solve the above problems.

[0006] The purpose and effect of an automatic chamfering machine for processing the outer edge of a piston ring of the utility model are achieved by the following specific technical means:

[0007] An automatic chamfering machine for processing the outer edge of a piston ring includes a grinding mechanism, a piston ring body, and a sliding mechanism. A clamping mechanism for clamping the piston ring body is provided on the grinding mechanism, and a feeding mechanism matching the clamping mechanism is installed on the sliding mechanism.

[0008] The clamping mechanism includes a first motor and an air pump installed on the grinding mechanism. A clamping block is installed at the rotating end of the first motor. An installation and clamping groove matching the piston ring body is opened in the middle of the front wall surface of the clamping block. An electric telescopic rod is provided directly below the first motor. A blowing head matching the clamping block is installed at the telescopic end of the electric telescopic rod. The blowing head is connected to the air outlet pipe head of the air pump.

[0009] The feeding mechanism includes a motor housing and a second motor installed inside the motor housing. A first disc is sleeved on the rotating rod of the second motor. One side wall surface of the first disc is fixedly installed with the motor housing. At the rotating end of the second motor, there is a second disc. A feeding mechanism is installed in the middle of the wall surface of the second disc close to the first disc. The feeding mechanism is rotatably arranged on the wall surface of the first disc. On the other surface of the second disc, an even number of piston ring storage sleeves for matching the piston ring body are evenly distributed. In the middle of the top surface of the motor housing, a pneumatic push rod is installed. At the telescopic end of the pneumatic push rod, an annular push plate for matching the piston ring storage sleeve is installed.

[0010] Further, the grinding mechanism includes a grinding control host and a grinding tool mechanism arranged above the grinding control host. The first motor is installed in the inner cavity of the grinding control host.

[0011] Further, two annular openings for matching the piston ring body are symmetrically opened on the outer wall surface of the first disc in the up-and-down direction. The annular openings are communicated with the piston ring storage sleeves. The annular opening above the first disc is coaxial with the center of the annular push plate. Above the front wall surface of the disc housing, a discharge opening for matching one of the piston ring storage sleeves directly above the second disc is opened.

[0012] Further, the piston ring storage sleeve directly above the second disc is coaxial with the center of the clamping block.

[0013] Further, an annular air passage is opened in the inner cavity of the clamping block. A plurality of air outlet holes communicating with the annular air passage are evenly opened in the installation clamping groove of the clamping block. At the lower end of the other surface of the clamping block, an air inlet bayonet communicating with the annular air passage is provided.

[0014] Further, a workpiece preset block for matching the annular opening directly below the first disc is provided in the middle of the sliding mechanism.

[0015] Further, a conveyor belt mechanism is also provided between the grinding mechanism and the sliding mechanism.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The piston ring body is ground by the grinding tool mechanism on the grinding control host. After grinding is completed, the electric telescopic rod drives the air blowing head to slide close to and be clamped with the air inlet bayonet of the clamping block. The air pump blows air and sends the air into the annular air passage in the clamping block. The air outlet holes of the clamping block discharge the air, blowing the piston ring body off and falling onto the conveyor belt mechanism and then being transported away, without the need for manual clamping and fixing of the piston ring.

[0018] 2. When the piston ring body in one of the piston ring storage sleeves of the present utility model is processed, the second motor rotates by a certain angle to drive the other piston ring storage sleeve to rotate to the directly upward position for processing the packing in the clamping block. When the first emptied piston ring storage sleeve rotates to the annular opening directly below the first disc, the piston ring body previously sleeved on the workpiece preset block is pushed into the piston ring storage sleeve, thereby completing one-time packing. By repeating this process, rapid packing processing can be achieved, continuous processing can be carried out without interruption, and the continuity is strong, greatly improving the processing efficiency.

[0030] Embodiment:

[0031] As shown in the attached Figure 1 to the attached Figure 6 figures: An automatic chamfering machine for the outer edge of a piston ring includes a grinding mechanism 1, a piston ring body 3, and a sliding mechanism 4. A clamping mechanism 2 for clamping the piston ring body 3 is provided on the grinding mechanism 1, and a feeding mechanism 5 matching the clamping mechanism 2 is installed on the sliding mechanism 4;

[0032] The clamping mechanism 2 includes a first motor 202 and an air pump 204 installed on the grinding mechanism 1. A clamping block 201 is installed at the rotating end of the first motor 202. An installation clamping groove matching the piston ring body 3 is formed in the middle of the front wall surface of the clamping block 201. An electric telescopic rod 203 is provided directly below the first motor 202. A blowing head matching the clamping block 201 is installed at the telescopic end of the electric telescopic rod 203, and the blowing head is connected to the air outlet pipe head of the air pump 204;

[0033] The feeding mechanism 5 includes a motor housing and a second motor 501 installed inside the motor housing. A first disc 504 is sleeved on the rotating rod of the second motor 501. One side wall surface of the first disc 504 is fixedly installed with the motor housing. At the rotating end of the second motor 501, there is a second disc 506. In the middle of the wall surface of the second disc 506 close to the first disc 504, a feeding mechanism 508 is installed. The feeding mechanism 508 is rotatably arranged on the wall surface of the first disc 504. On the other side of the second disc 506, an even number of piston ring storage sleeves 507 that match the use of the piston ring body 3 are evenly distributed. In the middle of the top surface of the motor housing, a pneumatic push rod 502 is installed. At the telescopic end of the pneumatic push rod 502, an annular push plate 503 that matches the use of the piston ring storage sleeve 507 is installed.

[0034] Therein, when several piston ring storage sleeves 507 are all filled with the piston ring body 3, the sliding mechanism 4 is driven to slide, driving the whole feeding mechanism 5 to approach the grinding mechanism 1, so that the piston ring storage sleeve 507 directly above is attached to the wall surface of the clamping block 201. At this time, the pneumatic push rod 502 pushes the annular push plate 503, so that one piston ring body 3 in the piston ring storage sleeve 507 directly above is snap-fitted and installed on the clamping block 201. After the snap-fitting installation is completed, the sliding mechanism 4 drives the feeding mechanism 5 to reset. The first motor 202 rotates to drive the clamping block 201 to rotate, and then the grinding mechanism 1 performs grinding. After the grinding is completed, the electric telescopic rod 203 drives the air blowing head to slide close to the clamping block 201 and communicate with its inner cavity. The air pump 204 blows air to blow the piston ring body 3 in the clamping block 201 out. Repeat the above process until the piston ring body 3 in the current piston ring storage sleeve 507 is processed. Then, the second motor 501 rotates a certain angle to drive another piston ring storage sleeve 507 to rotate to the directly above to fill the clamping block 201 for processing.

[0035] As shown in the appendix Figure 1 and the appendix Figure 5 As shown, in some embodiments, the grinding mechanism 1 includes a grinding control host 101 and a grinding tool mechanism 102 arranged above the grinding control host 101. The first motor 202 is installed in the inner cavity of the grinding control host 101. The grinding control host 101 is used to control all electrical devices. The grinding tool mechanism 102 is used to chamfer the clamping block 201 at different angles.

[0036] As shown in the appendix Figure 1 to the appendix Figure 4As shown, in some embodiments, two annular openings for mating with the piston ring body 3 are symmetrically formed on the outer wall surface of the first disk 504 in the vertical direction. The annular openings communicate with the piston ring storage sleeve 507. The annular opening above the first disk 504 is coaxial with the center of the annular push plate 503. An outlet opening for mating with one of the piston ring storage sleeves 507 directly above the second disk 506 is formed above the front wall surface of the disk housing 505. The annular opening above the outer wall surface of the first disk 504 is used to cooperate with the annular push plate 503 to slide into the piston ring storage sleeve 507 to push the piston ring body 3 in the piston ring storage sleeve 507 for use.

[0037] As shown in the Figure 1 to Figure 4 the appended drawings, in some embodiments, the piston ring storage sleeve 507 directly above the second disk 506 is coaxial with the center of the clamping block 201. The purpose of being coaxial is that after the second disk 506 rotates a certain angle, any of the piston ring storage sleeves 507 thereon can be matched with the clamping block 201 for use.

[0038] As shown in the Figure 6 appended drawings, in some embodiments, an annular air passage is formed in the inner cavity of the clamping block 201. A plurality of air outlet holes communicating with the annular air passage are evenly formed in the installation clamping groove of the clamping block 201. An air inlet bayonet communicating with the annular air passage is provided at the lower end of the other side of the clamping block 201. After processing is completed, air is introduced into the air inlet bayonet, so that the air outlet holes blow air outwards to blow the processed piston ring body 3 out of the installation clamping groove of the clamping block 201.

[0039] As shown in the Figure 1 to Figure 3 appended drawings, in some embodiments, a workpiece preset block 6 for mating with the annular opening directly below the first disk 504 is provided in the middle of the sliding mechanism 4. The workpiece preset block 6 is used to pre-sleeve the unprocessed piston ring body 3. When the first emptied piston ring storage sleeve 507 rotates to the position of the annular opening directly below the first disk 504, the piston ring body 3 pre-sleeved on the workpiece preset block 6 is pushed into the piston ring storage sleeve 507, thereby completing one-time filling. By repeating this process, rapid filling processing can be realized.

[0040] As shown in the Figure 1 appended drawings, in some embodiments, a conveyor belt mechanism 7 is further provided between the grinding mechanism 1 and the sliding mechanism 4. The purpose of setting the conveyor belt mechanism 7 is to transport the processed piston rings.

[0041] The specific usage mode and function of this embodiment are as follows: First, fill several piston ring storage sleeves 507 with piston ring bodies 3. Then, drive the electric slide rail 402 to drive the sliding bracket 401 to slide, driving the feeding mechanism 5 as a whole to approach the grinding mechanism 1, so that the piston ring storage sleeve 507 directly above is attached to the wall surface of the clamping block 201. At this time, control the pneumatic push rod 502 to push the annular push plate 503, so that one piston ring body 3 in the piston ring storage sleeve 507 directly above is pushed out of the inner cavity of the piston ring storage sleeve 507 by the annular push plate 503 and is snap-fitted and installed on the clamping block 201. After the snap-fitting installation is completed, the electric slide rail 402 slides to drive the feeding mechanism 5 on the sliding bracket 401 to reset as a whole. The first motor 202 rotates to drive the clamping block 201 to rotate, and then the grinding tool mechanism 102 on the grinding control host 101 grinds the piston ring body 3. After the grinding is completed, the electric telescopic rod 203 drives the air blowing head to slide close to and snap-fit into the air inlet bayonet of the clamping block 201. The air pump 204 blows air and sends it into the annular air duct in the clamping block 201. The air outlet holes of the clamping block 201 discharge the air, blowing the piston ring body 3 off and onto the conveyor belt mechanism 7 and then being transported away. Repeat the above process until the piston ring bodies 3 in the piston ring storage sleeve 507 at this time are processed. Then, rotate a certain angle by the second motor 501, drive another piston ring storage sleeve 507 to rotate to the position directly above to fill the clamping block 201 with materials for processing. When the first emptied piston ring storage sleeve 507 rotates to the annular opening directly below the first disc 504, push the piston ring body 3 previously sleeved on the workpiece preset block 6 into the piston ring storage sleeve 507, and thus complete the one-time filling of materials. Repeat this process to achieve rapid filling and processing.
