[0002] Ceramic cylinder liners are an important component of high-pressure mud pumps. They consist of a metal outer sleeve and a ceramic inner sleeve. The metal outer sleeve is machined, while the ceramic inner sleeve is sintered. When assembling the metal outer sleeve and ceramic inner sleeve, the metal outer sleeve needs to be heated to increase its size. The ceramic inner sleeve is then placed inside the metal outer sleeve. After the metal outer sleeve cools, it shrinks back to its original size, thus tightly securing the ceramic inner sleeve.

[0003] Traditional heating methods typically employ resistance heating or flame heating to heat the metal outer casing of ceramic cylinder liners. However, this can result in inaccurate temperature control and low heating efficiency, which in turn affects the quality of the heat treatment of the metal outer casing.

[0004] Therefore, there is a need to provide a new type of automatic constant temperature heating machine. Utility Model Content

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0032] like Figures 1 to 8 As shown, an automatic constant temperature heating machine includes a heating platform 1, a support plate 2 on the heating platform 1, and a placement box 3 for placing a ceramic cylinder sleeve 26 on the support plate 2. The support plate 2 also has an adjustable lifting mechanism, which is connected to a pressure plate 11 that presses the ceramic cylinder sleeve 26 into the placement box 3. The height of the lifting mechanism can be adjusted according to the height of the ceramic cylinder sleeve 26 in the placement box 3 to ensure that the pressure plate 11 can press the ceramic cylinder sleeve 26. To ensure that the pressure plate 11 can stably press the ceramic cylinder sleeve 26, when the pressure plate 11 is pressing on the ceramic cylinder sleeve 26, the pressure plate 11 is arranged parallel to the placement box 3. This way, when the pressure plate 11 presses on the ceramic cylinder sleeve 26, the ceramic cylinder sleeve 26 does not... The ceramic cylinder liner 26 may tip or tilt, ensuring that it can be stably placed and heated evenly within the placement box 3. The pressure plate 11 is movably connected to the lifting mechanism via a flipping mechanism, which can be manually controlled to move or open the pressure plate 11. The bottom of the heating platform 1 is equipped with a control box 4 that controls the temperature of the placement box 3 and the pressure plate 11. It is understood that the control box 4 is equipped with a constant temperature control panel to ensure that the control box 4 can maintain a constant temperature for heating the ceramic cylinder liner 26 within the placement box 3. The control box 4 is also equipped with temperature adjustment keys, on / off keys, and other components that can adjust the temperature of the control box 4 to achieve constant temperature heating of the ceramic cylinder liner 26 within the placement box 3.

[0033] The working principle of this embodiment:

[0034] Open the control box 4, set the constant temperature control panel to a constant temperature, place the ceramic cylinder sleeve 26 into the preheated placement box 3, and press the pressure plate 11 on top of the ceramic cylinder sleeve 26 to make the ceramic cylinder sleeve 26 stably placed in the placement box 3 and perform constant temperature heating. After heating for a certain period of time, remove the pressure plate 11 and take out the ceramic cylinder sleeve 26.

[0035] Specifically, the lifting mechanism includes a fixed platform 5 mounted on a support plate 2. An adjustable lifting rod 6 is installed within the fixed platform 5. A retainer 7, movable up and down along the lifting rod 6, is sleeved around the upper section of the lifting rod 6. A limit ring 8 is sleeved above the retainer 7 on the outer periphery of the lifting rod 6. The limit ring 8 can rotate around the lifting rod 6, and the retainer 7 can rotate around the lifting rod 6. Several fastening screws are provided on the outer periphery of the retainer 7. Tightening or loosening the fastening screws completes the lifting mechanism's movement. The fixing or loosening of the rod 6 is used to adjust the position of the limiting ring 8 on the lifting rod 6. The outer periphery of the limiting ring 8 is provided with a connecting hole 9, which is rotatably connected to the flipping mechanism. The flipping mechanism can rotate around the lifting rod 6 with the limiting ring 8. Therefore, when it is necessary to remove the pressure plate 11 from the ceramic cylinder sleeve 26, the top of the ceramic cylinder sleeve 26 can be removed by manually holding the flipping mechanism and rotating it around the lifting rod 6, which makes it easy to adjust the position of the ceramic cylinder sleeve 26 in the placement box 3 or to remove the ceramic cylinder sleeve 26 from the placement box 3.

[0036] Furthermore, a connector 10 is provided between the retainer 7 and the limiting ring 8. The connector 10 connects the retainer 7 and the limiting ring 8 so that the limiting ring 8 moves up and down along the lifting rod 6 together with the retainer 7. This allows for precise control of the position of the limiting ring 8 on the lifting rod 6, so as to satisfy the pressure plate 11 on the ceramic cylinder liner 26.

[0037] The flipping mechanism includes a first connecting rod 12, a second connecting rod 13, and a connecting plate 14. The first connecting rod 12 is rotatably connected to the connecting hole 9, the second connecting rod 13 is fixedly connected to the connecting plate 14, and the connecting plate 14 is welded to the pressure plate 11. The first connecting rod 12 and the second connecting rod 13 are hinged together. Since the pressure plate 11 directly presses against the top of the ceramic cylinder sleeve 26, the pressure plate 11 has a certain weight. To facilitate the movement of the pressure plate 11, a connecting plate 14 is welded to the upper end face of the pressure plate 11. This facilitates manual movement of the pressure plate 11 and reduces direct contact between the pressure plate and the cylinder sleeve 26. The contact between the pressure plate 11 and the pressure plate 12 at a constant temperature reduces safety hazards. At the same time, the hinged connection between the first connecting rod 12 and the second connecting rod 13 facilitates the upward flipping of the pressure plate 11. This is because, normally, the pressure plate 11 directly presses against the top of the ceramic cylinder liner 26. If the pressure plate 11 is directly rotated away around the lifting rod 6, the ceramic cylinder liner 26 may tip over. Therefore, by setting the pressure plate 11 to flip directly upward and then rotate it away around the lifting rod 6, it is ensured that the ceramic cylinder liner 26 will not tip over when the pressure plate 11 is removed, thus avoiding damage to the ceramic cylinder liner 26.

[0038] To enable the pressure plate 11 to flip upwards, specifically, a connecting block 15 is provided at the hinge end of the first connecting rod 12 and the second connecting rod 13. A limiting block 16 is provided at the bottom of the connecting block 15, and a hinge hole 17 is provided on the connecting block 15. A connecting groove 18 is provided at the hinge end of the second connecting rod 13 and the first connecting rod 12. Slots 19 that mate with the hinge hole 17 are provided on both sides of the connecting groove 18. The connecting block 15 extends into the connecting groove 18, and the limiting block 16 abuts against the bottom of the connecting groove 18. The connecting block 15 and the connecting groove 18 are connected by a pin 20 that can pass through the slot hole 19 and the hinge hole 17 to realize the hinged connection between the first connecting rod 12 and the second connecting rod 13. The bottom abutting setting of the limiting block 16 and the connecting groove 18 can ensure that the second connecting rod 13 rotates upward along the pin 20 without flipping downward, avoiding the second connecting rod 13 rotating downward along the pin 20, which would cause the pressure plate 11 to lose control and press on the ceramic cylinder liner, resulting in the damage of the ceramic cylinder liner 26.

[0039] The bottom of the heating platform 1 is provided with an L-shaped fixing bracket 21 for fixing the control box 4 to the bottom of the heating platform 1. The fixing bracket 21 is fixedly connected to the heating platform 1 by fixing screws, and the control box 4 is fixedly connected to the fixing bracket 21 by fixing screws.

[0040] In actual use, the control box 4 needs to heat the placement box 3 to ensure that the ceramic cylinder liner 26 can be heated at a constant temperature inside the placement box 3. Therefore, the placement box 3 is provided with several wiring holes 22, and each wiring hole 22 is electrically connected to the control box 4 through an electric wire.

[0041] Similarly, in actual use, the control box 4 needs to heat the pressure plate 11 to ensure that the top of the ceramic cylinder liner 26 is also heated evenly. Therefore, several wire inlet holes 23 are provided on the pressure plate 11, and each wire inlet hole 23 is electrically connected to the control box 4 through a wire.

[0042] To ensure that the ceramic cylinder liner 26 is securely placed in the placement box 3, several limiting holes 24 are provided at the bottom of the placement box 3 for fixing the bottom of the ceramic cylinder liner 26. To ensure that the pressure plate 11 can securely cover the ceramic cylinder liner 26, several abutment holes 25 that cooperate with the limiting holes 24 are provided on the side of the pressure plate 11 facing the placement box 3. When the pressure plate 11 covers the ceramic cylinder liner 26 in the placement box 3, the abutment holes 25 are used to abut and fix the top of the ceramic cylinder liner 26 to achieve the fixation of the ceramic cylinder liner 26 in the placement box 3.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
