Its design and material selection directly affect the performance, efficiency and durability of the engine. The engine cover is usually made of aluminum alloy or cast iron, with good strength and corrosion resistance. In order to ensure that it meets the use requirements, it is usually necessary to perform appropriate heat treatment on the engine cover during the processing of the engine cover to improve its mechanical properties and durability.

It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0049] See also Figures 1 to 11 The present invention provides a technical solution: a modified heat treatment device and method for engine case cover processing, the solution is as follows:

[0050] like Figure 1 , Figure 2 As shown, the modified heat treatment equipment mainly refers to a tempering furnace, which can perform modified heat treatment on the engine cover blank. The tempering furnace includes a furnace body 1, a crane-type furnace base 3 and a lifting door 4. The furnace body 1, the furnace base 3 and the lifting door 4 are all provided with insulation layers, and the furnace body 1 is provided with a heating component and a heat dissipation component to control the temperature in the furnace. The heating component can adopt a resistive heating device or a duct heating device. A guide rail 2 is provided at the bottom of the furnace body 1, and the furnace base 3 can be moved on the guide rail 2. The furnace base 3 is moved to the outside of the furnace body 1 to load the engine cover, and then the furnace base 3 is sent into the furnace body 1, and the lifting door 4 is closed to form a thermal insulation environment.

[0051] like Figure 3As shown, a loading mechanism for the engine cover is provided on the furnace base 3 of the present invention, and the loading mechanism can drive the engine cover to rotate to make up for the deficiency of the heating system, improve the uniformity of heating of the cover, and prevent the cover from deformation through a stable and uniform fixing structure.

[0052] like Figure 4 , Figure 5 As shown, a support column 5 is fixedly installed on the furnace base 3, and the support column 5 is symmetrically installed at both ends of the furnace base 3. A rotating shaft 6 is installed on the support column 5 through a bearing. A positioning structure is provided on the rotating shaft 6, which can be fixed at a corresponding angle. A rotating bracket 7 is fixedly installed on the rotating shaft 6, and a limiting groove 8 is provided on the rotating bracket 7. A slide seat 9 is installed in the limiting groove 8 for limiting sliding. The center rod 10 is installed through the slide seat 9, and the center rod 10 is connected to the pushing assembly, and the pushing assembly can drive the center rod 10 to move along the direction of the limiting groove 8. There are two limiting grooves 8 symmetrically arranged on the rotating bracket 7, so there are also two center rods 10 symmetrically arranged. A main splint 11 with a panel 12 is fixedly installed on the center rod 10. When fixing the engine cover, the engine cover is lifted between the two main splints 11, and then the main splint 11 is driven to move by the center rod 10, so that the cover can be initially fixed from the middle position.

[0053] like Figure 6 As shown, a docking seat 13 with a card slot is fixedly installed at the end of the rotating shaft 6, and a driving device 14 is installed on the outer surface of the lifting door 4. The driving device 14 can adopt a motor structure, and its driving shaft that can withstand high temperatures extends into the lifting door 4, and a telescopic shaft 15 is arranged on the driving shaft. When the lifting door 4 descends and closes, the telescopic shaft 15 can extend out and connect with the docking seat 13, thereby driving the rotating bracket 7 to rotate through the driving device 14, so that the box cover is in an active state.

[0054] like Figure 7 , Figure 8As shown, one end of the center rod 10 of the present invention is installed with the main splint 11, and the other end is fixedly installed with an end plate 16, and the end plate 16 can also move with the center rod 10. A right-angle guide cylinder 17 is arranged on the main splint 11, and a linear guide cylinder 18 is installed on the end plate 16. The two can guide the installation of the binding rope 19. Through the combination of four binding ropes 19, the box cover can be surrounded for binding and fixing. Two binding ropes 19 are symmetrically arranged on the main splint 11 and the end plate 16, and two main splints 11 and end plates 16 are symmetrically arranged on the rotating bracket 7. Therefore, the four binding ropes 19 form a set of fixed structures, and a plurality of binding ropes are arranged on the rotating bracket 7. The binding rope 19 can be bound and fixed along the box cover, and cooperate with the main splint 11 in the middle to firmly fix the engine box cover, so that it rotates with the rotating bracket 7 without causing damage to it. At the same time, the fixing method using the binding rope 19 can reduce the contact area between the fixed structure and the box cover, and minimize the impact of heat on it. One end of the binding rope 19 is fixedly installed with a quick-release connector 20, and the other end is fixedly installed with a traction column 21. The quick-release connectors 20 are respectively socket and plug structures, which are respectively arranged at the ends of the binding rope 19 of the two symmetrical main splints 11, so that the upper and lower binding ropes 19 can be connected together, thereby surrounding and fixing the engine box cover.

[0055] like Fig.10 As shown, the binding rope 19 is usually provided with a redundant length to facilitate the mutual connection of the two binding ropes 19. After the connection is completed, the binding rope 19 can be tightened by moving the traction column 21 to fix the box cover. The traction column 21 usually falls on the linear guide cylinder 18, and a lifting bracket 22 is movably installed on the end plate 16. The lifting bracket 22 can be driven by a pushing member, thereby simultaneously driving all the traction columns 21 on the end plate 16 to move, so as to tighten the binding rope 19.

[0056] like Fig.10 , Fig.11As shown, the main plate 11 of the present invention is also equipped with an auxiliary clamping structure that can be recovered as the binding rope 19 is tightened. The auxiliary clamping structure includes an axle seat 23 installed on the main plate 11, and a flip shaft 24 is rotatably installed on the axle seat 23. The flip shaft 24 is fixedly connected with a side clamping plate 25. The side clamping plate 25 can rotate with the flip shaft 24. Usually, the side clamping plates 25 are located on both sides of the main plate 11 in parallel. With the main plate 11, the two sides of the box cover are clamped and fixed to ensure the stability of the box cover. At the same time, the flip shaft 24 can be turned. A gear 26 is fixedly mounted on the rotating shaft 24, and a lifting plate 28 is slidably mounted on the main splint 11 via a guide rod 27. A rack 29 is fixedly connected to the lifting plate 28, which meshes with the gear 26. The lifting plate 28 is connected to the lifting bracket 22 via a connecting rod 30 and can move with the lifting bracket 22. Therefore, when the binding rope 19 is tightened, the rack 29 can drive the gear 26 to rotate, and then drive the side splint 25 to rotate via the flip shaft 24, and disengage from the panel 12 to avoid affecting the heating of the box cover.

[0057] like Fig. 9 As shown, at the same time, the binding rope 19 of the present invention has the ability to adjust its length to adapt to engine cover boxes of different sizes. A movable end 31 is provided on the traction column 21 to which the binding rope 19 is connected. The binding rope 19 is fixedly connected to the end 31. An adjustment frame 32 is fixedly installed on the traction column 21, and a plurality of bayonet holes 33 are provided on the adjustment frame 32. A spring pin 34 is provided on the end 31. By connecting the spring pin 34 of the end 31 with different bayonet holes 33, the length of the corresponding binding rope 19 after passing through the right-angle guide cylinder 17 can be adjusted to perform binding and fixing for cover boxes of different sizes.

[0058] When the present invention is in use: first, the furnace base 3 is pulled out of the furnace body 1 through the guide rail 2 to load the engine case cover blank. During loading, the rotating bracket 7 is in a vertical state, and the two main splints 11 are in a horizontal state, one up and one down, and the case cover is lifted between the two main splints 11. The sliding of the slide seat 9 in the limiting groove 8 drives the middle rod and the main splint 11 thereon to move, and the main splint 11 and the side splints 25 on both sides thereof can fix the case cover on the rotating bracket 7 from the middle; then, the corresponding two binding ropes 19 are connected together through the quick-release joint 20 so that they are wrapped around the engine case cover, and the lifting bracket 22 on the end plate 16 is lifted up by the push piece to drive the traction column 21 to move, so that the binding rope 19 shrinks along the case cover surface to bind and fix the case cover. At the same time, the lifting bracket 22 drives the lifting plate 28 on the main splint 11 to move, prompting the flip shaft 24 to drive the side splint 25 to rotate and detach from the case cover;

[0059] After the box cover is fixed, it is pushed into the furnace body 1 along with the furnace base 3, and the temperature in the furnace body 1 is controlled to complete the tempering work of the box cover blank.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
