Description

Technical Field

[0001] This invention relates to the field of piston deburring technology, and in particular to an automated piston deburring device and method. Background Technology

[0002] The piston is a reciprocating component in the cylinder block of a car engine. The basic structure of a piston can be divided into the top, head, and skirt. The piston top is the main part that makes up the combustion chamber, and its shape depends on the type of combustion chamber used. Figure 16 The diagram shows a piston structure in the prior art, including a piston body 80, on which an inner groove 801 and a circular groove 802 are provided. During the production of the piston, burrs will be generated on the inner and outer surfaces, so the piston needs to be deburred.

[0003] Chinese Patent Application No. 2020211295888 discloses a processing device for deburring pistons, including a base. An L-shaped support block and a support plate are installed at the left and right ends of the base. A first motor is fixedly installed on the vertical plate of the L-shaped support block. A first rotating shaft is fixedly connected to the output end of the first motor. A grinding roller for removing piston burrs is fixedly mounted on the first rotating shaft. A first bearing is fixedly connected to the other end of the first rotating shaft. The first bearing is fixed on the support plate. A positioning mechanism for fixing the piston and adjusting the piston position is slidably installed between the L-shaped support block and the support plate. The positioning mechanism is located directly in front of the grinding roller.

[0004] The deburring device described above can deburr the outer surface of the piston, but it is not convenient for deburring the inner side of the piston. Figure 16 The piston body 80 shown has an inner groove 801 and a circular groove 802. However, the above-mentioned deburring device is not convenient for cleaning the burrs in the inner groove 801 and the circular groove 802. Therefore, we propose an automated deburring device and method for pistons. Summary of the Invention

[0027] A mounting plate 320 is mounted on the flat plate 312. A rotary drive component e321 is mounted on the mounting plate 320. A swing arm 322 is mounted on the output end of the rotary drive component e321. A rotating shaft b323 is mounted on the swing arm 322. A grinding wheel b324 is mounted on the rotating shaft b323.

An arc-shaped block 329 is installed at the output end of the linear drive component c328.

[0028] In this embodiment, the robot arm 104 places the piston body 80 onto the transmission belt 106. It should be noted that the piston body 80 placed on the transmission belt 106 has its opening facing downward. The rotation drive a108 drives the drive wheel a105 to rotate, and the piston body 80 is transmitted to the connecting block 326 through the transmission belt 106. The arc block 329 limits the piston body 80. The linear drive a302 drives the motion rod 303 to move upward, driving the insertion block 304 to pass through the round hole 3261 and insert into the inner groove 801, driving the piston body 80 on the connecting block 326 to move upward, and transmitting it to the outer deburring station. It should be noted that the insertion block 304 adsorbs the piston body 80 by negative pressure, which is a conventional technical means in this field and will not be described in detail here.

[0029] In this embodiment, the rotary drive d319 drives one of the rotary rods 313 to rotate, which in turn drives the two swing arms 314 to rotate inward, and drives the two grinding wheels a316 to contact the outside of the piston body 80. The rotary drive c317 drives the grinding wheel a316 to rotate. The linear drive a302 drives the piston body 80 to move up and down, and the rotary drive b306 drives the motion rod 303 to rotate, which in turn drives the piston body 80 to rotate; the grinding wheels a316 rotating on both sides grind the sides of the piston body 80 to remove burrs from the sides of the piston body 80. The rotary drive component e321 drives the swing arm 322 to rotate downwards, driving the grinding wheel b324 to contact the top surface of the piston body 80.

[0031] Example 2 like Figures 1-15 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: like Figures 1-15As shown, the internal deburring mechanism 4 in this embodiment includes: a mounting frame 401, which is disposed on the ground; a motion drive component 402, which is disposed on the mounting frame 401; an arc-shaped frame 403, which is mounted on the output end of the motion drive component 402; a sliding frame 404, which is slidably disposed on the arc-shaped frame 403; a connecting rod 405, which is mounted on the bottom of the sliding frame 404; an insertion rod 406, which is mounted on the bottom of the connecting rod 405; and an airbag 407. 7 is installed on the outside of the insertion rod 406. The outside of the airbag 407 is provided with metal bristles. It should be noted that the motion drive 402 can drive the arc frame 403 to move up and down, and can also drive the arc frame 403 to rotate. The motion drive 402 is preferably a combination of a motor and a cylinder. A through groove 4060 is opened in the insertion rod 406. Liquid or gas is filled into the airbag 407 through the through groove 4060 to inflate the airbag 407. The through groove 4060 is connected to the liquid supply equipment or gas source through the pipe. This is a conventional technical means in this field and will not be described in detail here.

[0032] In this embodiment, the piston body 80 (after external grinding) is transferred to the receiving groove 2021 by the transmission belt 106. The rotation drive g203 drives the drive wheel b204 to rotate, and drives the rotating sleeve c202 to rotate 180 degrees, flipping the piston body 80 in the receiving groove 2021. Then, the piston body 80 is transferred to the internal deburring station by the transmission belt 106. The linear drive component f417 drives the limiting ring 418 to move downward and fit over the piston body 80, thus limiting the piston body 80.

[0033] An arc-shaped rack 408 is provided on the outer side of the arc-shaped frame 403. A rotary drive h409 is installed on the sliding frame 404. A gear b410 is installed at the output end of the rotary drive h409. The gear b410 meshes with the arc-shaped rack 408. A guide rail 411 is installed on the mounting frame 401. A moving block 412 is slidably provided on the guide rail 411. A connecting plate 413 is installed on the moving block 412. A motion drive 402 is installed on the connecting plate 413. A linear drive e414 is installed on the mounting frame 401. The output end of the linear drive e414 is connected to the moving block 412. A fixed plate 416 is installed on one of the conveyor frames 102. A linear drive f417 is installed on the fixed plate 416. A limit ring 418 is installed at the output end of the linear drive f417. Multiple locking blocks 4181 are provided inside the limit ring 418.

[0034] In this embodiment, the motion drive 402 drives the insertion rod 406 to move downward until the insertion rod 406 is inserted into the inner groove 801 of the piston body 80, and liquid is filled into the air bag 407. The air bag 407 expands and contacts the inner groove 801 of the piston body 80. The motion drive 402 drives the insertion rod 406 to rotate back and forth and move up and down. The metal bristles on the air bag 407 polish the inner groove 801 and remove the burrs on the surface of the inner groove 801. As liquid continues to be injected into the airbag 407, the airbag 407 expands and contacts the inner groove 801 and circular groove 802 of the piston body 80 (the airbag 407 expands and inserts into the circular groove 802). The rotary drive component h409 drives the gear b410 to rotate, thereby driving the sliding frame 404 to reciprocate along the arc frame 403, driving the airbag 407 to rotate around the circular groove 802 (i.e., Figure 15 Point M in the diagram makes a reciprocating arc motion. The metal bristles on the airbag 407 not only polish the inner groove 801, but also polish the circular groove 802, removing burrs from the inner surface of the circular groove 802. This allows for a more comprehensive deburring operation inside the piston body 80.

[0035] An electromagnet 415 is provided inside the insertion rod 406. A placement box is provided on one side of the mounting bracket 401. A conductive end 4150 is provided on the electromagnet 415. The conductive end 4150 is connected to a wire. It is a conventional technical means to energize the electromagnet 415 through the wire and the conductive end 4150, which will not be described in detail here. When the electromagnet 415 inside the insertion rod 406 is energized, it generates magnetic attraction, which attracts the metal debris generated during grinding inside the piston body 80, driving the insertion rod 406 to move upward and causing the airbag 407 to move synchronously. The linear drive component e414 drives the moving block 412 to move backward, driving the airbag 407 to move above the placement box. When the electromagnet 415 is de-energized, liquid is simultaneously injected into and expelled from the airbag 407, driving the airbag 407 to expand and contract rapidly, generating vibration on the airbag 407. This facilitates the falling of metal debris from the surface of the airbag 407 into the placement box, cleaning the metal debris generated inside the piston body 80 due to grinding.

[0036] Example 3: This example provides an automated deburring method for pistons, including the following steps: Step 1, Transmission process: The robot arm 104 places the piston body 80 onto the transmission belt 106. It should be noted that the piston body 80 placed on the transmission belt 106 has its opening facing downwards. The rotation drive a108 drives the drive wheel a105 to rotate, and the piston body 80 is transmitted to the connecting block 326 through the transmission belt 106. The arc-shaped block 329 limits the piston body 80. Step 2, Lifting process: The linear drive component a302 drives the motion rod 303 to move upward, drives the insertion block 304 to pass through the round hole 3261 and insert into the inner groove 801, drives the piston body 80 on the connecting block 326 to move upward, and transmits it to the outer deburring station. Step 3, outer deburring process: Rotary drive component d319 drives one of the rotating rods 313 to rotate, which drives the two swing arms 314 to rotate inward, driving the two grinding wheels a316 to contact the outer side of the piston body 80, and rotary drive component c317 drives the grinding wheel a316 to rotate. The linear drive a302 drives the piston body 80 to move up and down, and the rotary drive b306 drives the motion rod 303 to rotate, which in turn drives the piston body 80 to rotate; the grinding wheels a316 rotating on both sides grind the sides of the piston body 80 to remove burrs from the sides of the piston body 80. The rotary drive component e321 drives the swing arm 322 to rotate downwards, driving the grinding wheel b324 to contact the top surface of the piston body 80. The rotary drive component f325 drives the grinding wheel b324 to rotate and grind the top surface of the piston body 80 to remove burrs from the top surface of the piston body 80. Step 4, Flipping Process: The piston body 80 (after external grinding) is transferred to the receiving groove 2021 via the transmission belt 106. The rotation drive g203 drives the drive wheel b204 to rotate, which in turn drives the rotating sleeve c202 to rotate 180 degrees, flipping the piston body 80 in the receiving groove 2021. Then, the piston body 80 is transferred to the internal deburring station via the transmission belt 106. The linear drive component f417 drives the limiting ring 418 to move downward and fit over the piston body 80, thus limiting the piston body 80. Step 5, First internal deburring process: The motion drive 402 drives the insertion rod 406 to move downward until the insertion rod 406 is inserted into the inner groove 801 of the piston body 80, liquid is filled into the air bag 407, the air bag 407 expands and contacts the inner groove 801 of the piston body 80, the motion drive 402 drives the insertion rod 406 to rotate back and forth and move up and down, the metal bristles on the air bag 407 polish the inner groove 801 and remove the burrs on the surface of the inner groove 801; Step Six, Second Internal Deburring Process: Liquid continues to be injected into the airbag 407. The airbag 407 expands and contacts the inner groove 801 and circular groove 802 of the piston body 80 (the airbag 407 expands and inserts into the circular groove 802). The rotating drive component h409 drives the gear b410 to rotate, thereby driving the sliding frame 404 to reciprocate along the arc frame 403, driving the airbag 407 to rotate around the circular groove 802 (i.e., Figure 15Point M in the diagram makes a reciprocating arc motion. The metal bristles on the airbag 407 not only polish the inner groove 801, but also polish the circular groove 802 to remove the burrs on the inner surface of the circular groove 802. This allows for a more comprehensive deburring operation inside the piston body 80. Step 7, Cleaning process: The electromagnet 415 inside the insertion rod 406 is energized to generate magnetic attraction, which attracts the metal debris generated by grinding inside the piston body 80, drives the insertion rod 406 to move upward, and drives the airbag 407 to move synchronously. The linear drive component e414 drives the moving block 412 to move backward, and drives the airbag 407 to move above the placement box. When the electromagnet 415 is de-energized, liquid is simultaneously injected into and expelled from the airbag 407, driving the airbag 407 to expand and contract rapidly, generating vibration on the airbag 407. This facilitates the falling of metal debris from the surface of the airbag 407 into the placement box, cleaning the metal debris generated inside the piston body 80 due to grinding.
