Because the slides 5 are provided, the slides 5 can slide in the tempering furnace 1, and play a role in supporting and limiting the movable platform 2. With the use of the slide rods 14, the slide rods 14 can slide freely at the top position of the tempering furnace 1, and play a role in supporting and limiting the two furnace covers 3, thereby improving the horizontal movement stability of the movable platform 2.

[0028] A push assembly 6 is provided below the tempering furnace 1. The push assembly 6 is installed in two supporting legs 7. One end of the push assembly 6 is fixedly connected to one side of the bottom of the tempering furnace 1. The other end of the push assembly 6 is fixed to the bottom of one of the furnace covers 3.

The top of the extension block 604 is fixed to the bottom of one of the furnace covers 3. A moving wheel 605 is installed at the bottom of the extension block 604. The electric hydraulic rod 601 drives one of the furnace covers 3 and the mobile platform 2 to move through the extension block 604. One side of the mobile platform 2 is fixed to the furnace cover 3 on the other side, thereby facilitating the adjustment of the positions of the two furnace covers 3 and the diaphragm springs on the mobile platform 2. During the movement of the furnace cover 3, the moving wheels 605 can roll on the ground to support the furnace cover 3 and improve the stability of the movement of the furnace cover 3 and the mobile platform 2.

[0029] A middle partition plate 8 is installed in the middle of the movable platform 2. Because of the middle partition plate 8, the middle partition plate 8 can cooperate with the two furnace covers 3 to seal the left and right openings of the tempering furnace 1 respectively as the movable platform moves left and right, so as to facilitate the closing of the tempering furnace 1 and facilitate the stress relief heat treatment of the diaphragm spring.

[0030] A plurality of sleeve rods 9 are respectively provided on both sides of the middle partition 8, and an adjustment assembly 10 is installed in the sleeve rod 9. The adjustment assembly 10 includes a push rod 101, which is slidably connected in the sleeve rod 9. The top end of the push rod 101 passes through the sleeve rod 9 and is fixedly connected with a pressing block 103. Two slip rings 102 are clamped on the outside of the push rod 101, and the slip ring 102 is slidably connected in the sleeve rod 9. The bottom end of the push rod 101 is connected to the deflection assembly 12.

[0031] A support plate 11 is provided below the outer wall of the sleeve rod 9. The diameter of the support plate 11 is much larger than the diameter of the sleeve rod 9. The bottom of the support plate 11 is connected to the top of the deflection assembly 12. Because of the support plate 11, when the diaphragm spring is loaded, the bottom diaphragm spring can contact the support plate 11, thereby supporting the diaphragm spring and preventing the diaphragm spring from being stuck on the sleeve rod 9 and the deflection assembly 12.

[0032] The deflection assembly 12 includes a movable block 121, a rectangular groove 122 is provided at the top of the movable block 121, a slide plate 123 is slidably connected in the rectangular groove 122, support rods 124 are hinged on both sides of the slide plate 123 through pins, a clamping rod 125 is hinged on the top of the support rod 124 through a pin, and the clamping rod 125 passes through the movable block 121 and is clamped in the support assembly 13; the top of the slide plate 123 is fixedly connected to the bottom end of the push rod 101, and the bottom of the slide plate 123 is fixedly connected to a spring 126, which is installed between the slide plate 123 and the bottom of the inner wall of the rectangular groove 122.

[0033] The support assembly 13 is fixedly connected to the mobile platform 2, and the support assembly 13 includes two baffles 131. The bottoms of the two baffles 131 are fixed to the top of the mobile platform 2. A pin 132 is installed between the two baffles 131. The pin 132 passes through the bottom of the rotatably connected movable block 121 and is hinged to the two baffles 131 through the pin 132; a slot 133 is opened on one side of the baffle 131 corresponding to the position of the clamping rod 125, and the end of the clamping rod 125 away from the movable block 121 is inserted into the slot 133.

[0034] By setting a spring 126, the slide plate 123 is supported by the elastic force of the spring 126, so that the slide plate 123 moves up and pushes the two support rods 124 to deflect, so that the two support rods 124 respectively push the two clamping rods 125 away from each other, which is convenient for the clamping rod 125 to be clamped into the clamping groove 133, thereby improving the convenience of operation; through the mutual cooperation between the push rod 101 and the pressing block 103, the pressing block 103 is pressed down to drive the push rod 101 to move downward, and the push rod 101 squeezes the slide plate 123 to move downward. Because the slide plate 123 is hinged with the two support rods 124, the process of the slide plate 123 moving downward During the process, the two support rods 124 can be pulled, so that the positions of the slide plate 123 and the support rod 124 can be adjusted from the top of the sleeve rod 9; because a pin 132 is provided, the pin 132 passes through the movable block 121, so that the movable block 121 can drive the sleeve rod 9 to rotate, and the diaphragm spring can be conveniently taken and placed by adjusting the angle of the sleeve rod 9; through the mutual cooperation between the clamping rod 125 and the clamping groove 133, the clamping rod 125 can be clamped into the clamping groove 133, so as to achieve the purpose of locking the movable block 121 and the support assembly 13, so that the sleeve rod 9 will not deflect freely, and the diaphragm spring can be stably sleeved outside the sleeve rod 9.

[0035] The working principle of the present invention is:

[0036] When in use, the pressing block 103 is pressed down to drive the push rod 101 to move downward, and the push rod 101 squeezes the slide plate 123 to move downward. Since the slide plate 123 is hinged to the two support rods 124, the two support rods 124 can be pulled during the downward movement of the slide plate 123. The deflection of the two support rods 124 can pull the two clamping rods 125, so that the two clamping rods 125 are close to each other. When the clamping rod 125 is out of the clamping groove 133 on the baffle 131, the movable block 121 can rotate around the pin 132, so that the sleeve rod 9 tilts outward, and all the diaphragm springs outside the sleeve rod 9 can be pushed out of the sleeve rod 9. The other sleeve rods 9 can be operated in the same way.

[0037] When loading the diaphragm spring, align the batch of diaphragm springs so that the center hole of the diaphragm spring is aligned with the sleeve rod 9 and pushed in, so that the diaphragm spring can be sleeved outside the sleeve rod 9, and the sleeve rod 9 is pulled upward, so that the sleeve rod 9 drives the movable block 121 to deflect in the support assembly 13. When the sleeve rod 9 is in a vertical state, the clamping rod 125 outside the movable block 121 corresponds to the clamping groove 133 on the baffle 131, and the slide plate 123 is supported by the elastic force of the spring 126, so that the slide plate 123 moves up and pushes the two support rods 124 to deflect, so that the two support rods 124 push the two clamping rods 125 away from each other respectively, so that the clamping rod 125 can be clamped into the clamping groove 133, thereby achieving the purpose of locking the movable block 121 and the support assembly 13, so that the sleeve rod 9 will not deflect freely, and the diaphragm spring can be stably sleeved outside the sleeve rod 9.

[0038] When the tempering furnace 1 is used to perform stress relief heat treatment on the diaphragm spring on the movable platform 2, the electric hydraulic rod 601 is controlled to contract, so that the electric hydraulic rod 601 drives one of the furnace covers 3 to move through the extension block 604, so that the furnace cover 3 is close to the tempering furnace 1, and the sleeve rod 9 and the diaphragm spring on the right side of the middle partition 8 can be moved out of the tempering furnace 1, and the diaphragm spring on the left side of the middle partition 8 can enter the tempering furnace 1 until the left furnace cover 3 seals the left opening of the tempering furnace 1, and the middle partition 8 can seal the right opening of the tempering furnace 1, so that the tempering furnace 1 is closed, and the tempering furnace 1 can work to the diaphragm on the left side of the middle partition 8. The leaf spring undergoes stress relief heat treatment, and the diaphragm spring on the right side of the middle partition 8 is exposed. The diaphragm spring outside the sleeve rod 9 is removed and reloaded. After the diaphragm spring inside the tempering furnace 1 completes the stress relief heat treatment, the electric hydraulic rod 601 extends and pushes the extension block 604 and the left furnace cover 3 to move to the left. At the same time, the right furnace cover 3 can drive the right diaphragm spring to move into the tempering furnace 1 for stress relief heat treatment. At this time, the middle partition 8 can seal the left opening of the tempering furnace 1, and the right furnace cover 3 can seal the right opening of the tempering furnace 1. The operation is circulated in this way to always keep the tempering furnace 1 in working condition.
