Description

[0002] The CAT rocker arm is used for parts on the curved large arm of a small and medium-sized excavator, and has high performance requirements; the heat treatment quality requirement is strict, and the key is that the quenching hardness needs to be immediately detected (standard HB: 2.5mm-3.0mm) at the end of direct quenching by medium water, if the quenching hardness does not meet the standard requirement, rework is needed, which requires the quenching of the product to be controlled through the furnace loading to meet the quenching hardness requirement, so as to avoid a large amount of rework and cause certain loss to the production cost. Therefore, a simple and practical heat treatment "quenching tooling" is urgently needed to improve the quenching quality of the casting;

[0005] 2. When the original single-layer furnace loading is used to fix the excavator rocker arm, iron wire is used to fix the excavator rocker arm, but in the quenching process, the iron wire will soften and elongate under high temperature conditions, and the excavator rocker arm is prone to falling over, resulting in quenching failure.

[0032] The main tray plate 1 is provided with two trapezoidal clamping seats 4, which are designed in a groove type. One side of the trapezoidal clamping seat 4 is fixedly connected with a hinged plate 5. The trapezoidal clamping seat 4 is provided with a fixed seat equidistant moving mechanism and a clamping fine adjustment mechanism.

[0033] The trapezoidal clamping seat moving mechanism comprises a bidirectional threaded rod 6, a sliding rod 7, two pairs of threaded sleeves 8, two sliding sleeves 9, a connecting piece 10 and two connecting clamping shafts 11. The bidirectional threaded rod 6 is rotatably connected in the control shell 2. The two pairs of threaded sleeves 8 are respectively threadedly connected at both ends of the bidirectional threaded rod 6, and the distance between each pair of threaded sleeves 8 is equal. The sliding rod 7 is rotatably connected in the matching shell 3. The sliding sleeve 9 is slidably connected on the sliding rod 7. The connecting piece 10 is fixedly connected on each pair of threaded sleeves 8 and each sliding sleeve 9. The control shell 2 and the matching shell 3 are both provided with a moving port at the top. The connecting piece 10 is slidably connected in the moving port. The two connecting clamping shafts 11 are fixedly connected at both ends of the connecting piece 10. The bidirectional threaded rod 6 is coaxially fixedly connected with a control handle 12 through the control shell 2. The trapezoidal clamping seat 4 is fixedly connected with the two connecting clamping shafts 11 on the corresponding side. When it is necessary to adjust the distance between the two trapezoidal clamping seats 4, the control handle 12 can be manually controlled to rotate.

[0036] The working principle of the present application is as follows:

[0037] The air holes arranged on the main tray plate 1 can better ventilate the excavator rocker arm during quenching, so that the subsequent quenching strength is higher.

[0038] When the spacing between the two trapezoidal clamping seats 4 needs to be adjusted, the control handle 12 can be manually controlled to rotate, and when the control handle 12 rotates, the coaxially fixed double-threaded rod 6 connected with the control handle 12 can also rotate, and the two pairs of threaded sleeves 8 threaded at both ends of the double-threaded rod 6 will move closer or farther away from each other, and the connecting piece 10 fixedly connected to the threaded sleeve 8 will be connected through the connecting clamping shaft 11, so that the spacing between the two trapezoidal clamping seats 4 can be adjusted. When the trapezoidal clamping seat 4 moves, the connecting piece 10 at the other end will also drive the sliding sleeve 9 to slide on the sliding rod 7, thereby ensuring the stability of the trapezoidal clamping seat 4 during movement. By setting the trapezoidal clamping seat moving mechanism, the spacing between the two trapezoidal clamping seats 4 is adjusted by rotating the double-threaded rod 6, so that when facing different sizes of excavator swing arms, the appropriate clamping point can be found to clamp and fix the excavator swing arm, thereby ensuring the clamping and fixing efficiency.

[0039] When the spacing between the various fixed seats 14 needs to be adjusted, only the cross wrench needs to be inserted into the cross slot seat 18 to rotate, and the threaded rod 15 coaxially fixedly connected with the cross slot seat 18 will rotate, and the fixed seat 14 threaded with the threaded rod 15 will move closer or farther away from one end of the cross slot seat 18. By connecting the bent hinged chain 13, the spacing between the other ten fixed seats 14 can be adjusted, and when moving, the distance between each fixed seat 14 is equal. By setting the fixed seat equidistant moving mechanism, the rotation of the threaded rod 15 drives one fixed seat 14 to move horizontally, and the connection of the bent hinged chain 13 allows multiple fixed seats 14 to move equidistantly, thereby strictly controlling the spacing between the various excavator swing arms to be equal on the basis of processing multiple excavator swing arms at one time, thereby improving the cooling speed of the excavator swing arm and improving the hardenability of the casting;

[0040] The clamping fine adjustment mechanism can fix the excavator rocker arm, place the excavator rocker arm on the L-shaped clamping seat 21 on the fixed seat 14 corresponding to the two trapezoidal clamping seats 4, rotate the rocking handle 31 manually, and the adjustment tooth column 19 fixedly connected coaxially with the rocking handle 31 can rotate, when the adjustment tooth column 19 rotates, the transmission gear 25 engaged with the adjustment tooth column 19 can rotate, the driving bevel gear 27 fixedly connected coaxially with the transmission gear 25 can rotate, the driven bevel gear 28 engaged with the driving bevel gear 27 rotates, and the transmission shaft 29 fixedly connected coaxially with the driven bevel gear 28 can control the shift lever 30 to move in the through groove, since the length of the shift lever 30 is fixed, the clamping plate 24 can move to one end of the L-shaped clamping seat 21 at this time, thereby fixing the excavator rocker arm, by arranging the trapezoidal clamping seat moving mechanism, the interval between the two trapezoidal clamping seats 4 is adjusted through the rotation of the bidirectional threaded rod 6, so that the suitable clamping point for the excavator rocker arm can be found when facing excavator rocker arms of different sizes, thereby ensuring the clamping fixing efficiency.
