Description

Technical Field

[0002] The valve is one of the important parts of the automobile engine. It is subjected to high mechanical and thermal loads during operation. The exhaust valve is washed by high-temperature exhaust gas, so the thermal load is higher. The temperature of the intake valve is 300~500℃, and the temperature of the exhaust valve can reach 600~800℃, or even higher. Especially when the exhaust valve is just opened, the pressure in the cylinder is relatively high, and the valve opening is still small. The high-temperature gas is blown out through the gap between the valve and the valve seat at a very high speed (up to 600m / s), causing the valve to be strongly exposed to high temperature and corrosion.

[0039] In this embodiment, the intercepting mechanism 8 includes a guide rod 4 801, which is fixedly connected to the slide rail 1. A pushing sleeve 802 is slidably connected to the guide rod 4 801.

[0041] In this embodiment, when the pull rope 810 is pulled to make the elastic guide rod 812 stay at the second positioning slope 817, the pushing plate 803 and the extension rod 808 are staggered to avoid obstruction to the extension rod 808, and when the wedge block 820 passes over the sliding plate 813, the accommodating groove 819 can provide the elastic guide rod 812 with movement space to avoid the device from getting stuck.

[0042] In this embodiment, the feeding mechanism 9 includes a base 901, on which a rotating rod 902 is rotatably connected, and a feeding tray 903 is fixedly connected to the rotating rod 902. A number of storage racks 904 are evenly placed on the feeding tray 903, and the storage racks 904 are used to place valves. A spur gear three 905 is rotatably connected to the top of the rotating rod 902, and a ratchet 906 is also fixedly connected to the top of the rotating rod 902. A pawl 907 is provided on the spur gear three 905, and the ratchet 906 engages with the pawl 907. A rack three 908 is fixedly connected to the sliding mounting seat 301, and the rack three 908 engages with the spur gear three 905 during movement.

[0043] In this embodiment, during the movement of the sliding mounting seat 301, the rack three 908 will engage with the spur gear three 905 to drive the spur gear three 905 to rotate. Since the transmission of the ratchet 906 is a one-way transmission, the feeding tray 903 will only be driven to rotate when the sliding mounting seat 301 is moved away from the top of the feeding mechanism 9.

[0044] When this valve multi-temperature section heat treatment system is working, the working process is as follows:

[0045] Start the driving motor 501, the driving motor 501 drives the transmission sleeve 3 504 to rotate through the rotating shaft 3 502, the transmission sleeve 3 504 drives the rotating sleeve 1 connected thereto to rotate, the rotating sleeve 1 drives the rotating shaft 1 302 to rotate through the bevel gear set 1 308, the rotating shaft 1 302 drives the spur gear 1 303 meshing with the rack 1 304 to rotate, and by changing the rotation direction of the driving motor 501, the sliding mounting seat 301 can be controlled to reciprocate on the slide rail 1;

[0046] When the sliding mounting seat 301 moves toward the material storage rack 904, the guide rod 707 will enter the transverse groove 704. When the end of the lifting hook body 604 moves to the bottom of the material storage rack 904 handle, the guide rod 707 will enter the inclined groove 705. With the movement of the sliding mounting seat 301, the mounting block 602 and the lifting hook body 604 will move upward under the push of the inclined groove 705, and the material storage rack 904 will be lifted from the feeding tray 903. When the guide rod 707 moves out of the inclined groove 705, the sliding mounting seat 301 will continue to move for a distance and then start to move in the opposite direction, so that the check plate 706 that has been pushed open can be reset, so that the guide rod 707 can pass from above the guide block 702, so that the material storage rack 904 will not touch the feeding tray 903 again.

[0047] When the sliding mounting seat 301 carries the material storage rack 904 to move toward the heating chamber 201 of the corresponding temperature, the pull rope 810 corresponding to the heating chamber 201 is pulled to make the elastic guide rod 812 stuck at the positioning slope 1 816. When the sliding mounting seat 301 moves to this position, the wedge block 820 on the sliding mounting seat 301 will push the sliding plate 813 to move downward, thereby releasing the restriction on the elastic guide rod 812, so that the sliding sleeve 802 slides along the lower guide rod 4 801 under the elastic force of the spring 3 804. Under the guidance of the second guide groove 807, the push sleeve 802 will rotate during the movement, so that the push plate 803 is directly opposite to the extension rod 808, and then the push plate 803 will abut against the extension rod 808, pushing the extension rod 808 and the second sliding block 508 along the moving rotation axis 3 502, so that the first connector 307 and the third connector 505 are separated, the second connector 409 and the fourth connector 506 are engaged, the sliding mounting seat 301 stops moving, and the driving motor 501 starts to drive the screw rod 402 to rotate;

[0048] The rotation of the screw rod 402 will cause the nut 405 threadedly connected thereto to move downward together with the sliding block 1 404. After moving down to the bottom of the material storage rack 904 and abutting against the bottom surface of the heating chamber 201, the sliding block 1 404 is continuously controlled to move downward, which will cause the mounting block 602 to abut against the handle of the material storage rack 904, thereby reducing the distance between the mounting bracket 1 406 and the mounting block 602, and the spur gear 2 606 will mesh with the rack 2 608 to drive the lifting hook body 604 to rotate to a vertical position. At the same time, the upper end of the locking guide rod 6093 will also move above the guide groove 1 6092, and then the sliding block 1 404 will move upward, and the locking guide rod 6093 will be stuck in the groove above the guide groove 1 6092, so that the lifting hook body 604 is kept in a vertical position, so that the lifting hook mechanism 6 can be directly moved out of the heating chamber 201, and then the heating chamber 201 can be closed to heat the valve;

[0049] After the heating is completed, the heating chamber 201 is opened, and the sliding block 404 is controlled to move downward, so that the mounting block 602 is again abutted against the handle of the material storage rack 904, so that the locking guide rod 6093 moves up from the top of the groove, and then the sliding block 404 is controlled to move upward, and the guide groove 6092 will return from the top of the guide groove 6092 to the bottom of the guide groove 6092, so that the distance between the mounting block 602 and the mounting bracket 406 is increased under the push of the spring 2 603, and the hook body 604 is lifted from the vertical position. The flip will tilt the position, at which time the upward lifting hook mechanism 6 can lift the material storage rack 904 out of the heating chamber 201, and then pull the pull rope 810 again to make the elastic guide rod 812 stop at the second positioning slope 817. At this time, the push plate 803 is disengaged from the extension rod 808, and under the elastic force of the spring 1 509, the connector 2 409 and the connector 4 506 are separated, and the connector 1 307 and the connector 3 505 are engaged. At this time, the drive motor 501 can control the movement of the sliding mounting seat 301 again.
