[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: A cam plate quenching device, such as Figures 1-7 As shown, it includes a vertically arranged round rod 1, on which multiple cam plates 2 and multiple spacers 3 are fitted. The cam plates 2 and spacers 3 are spaced apart, that is, there is a spacer 3 between two adjacent cam plates 2. The upper and lower ends of the round rod 1 are respectively provided with a first positioning rod 4 and a second positioning rod 5. The first positioning rod 4 and the second positioning rod 5 have the same structure. The first positioning rod 4 and the second positioning rod 5 are also vertically arranged and coaxial with the round rod 1. The ends of the first positioning rod 4 and the second positioning rod 5 respectively abut against the upper and lower end faces of the round rod 1. The lower part of the round rod 1 is vertically engaged with a positioning plate 6.

[0026] In use, the first positioning rod 4 and the second positioning rod 5 are used to longitudinally restrict the round rod 1, and the positioning plate 6 is used to laterally restrict the round rod 1. The round rod 1 is kept vertical by the combination of longitudinal and lateral restrictions. At the same time, multiple cam plates 2 are loaded on the round rod 1 so that multiple cam plates 2 are quenched at the same time to improve the quenching efficiency. The spacer 3 is set to separate two adjacent cam plates 2.

[0027] Furthermore, such as Figure 2As shown, the lower part of the round rod 1 extends outward to form a limiting boss 101, which is annular. The upper part of the round rod 1 is threaded with a cap 7. The limiting boss 101 and the cap 7 cooperate to limit and fix the multiple cam pieces 2 and spacers 3 mounted on the round rod 1, so that the cam pieces 2, spacers 3 and round rod 1 form a whole, so as to facilitate the connection with the first positioning rod 4, the second positioning rod 5 and the positioning plate 6.

[0028] Preferably, the outer surface of the round rod 1 is provided with an external thread, and the inner wall of the cap 7 is provided with an internal thread that matches the external thread. The cap 7 is installed on the round rod 1 through the threaded connection of the external and internal threads. The external thread can extend from the upper part to the lower part of the outer surface of the round rod 1, or it can be located only at the upper part of the outer surface of the round rod 1. When it is located only at the upper part of the outer surface of the round rod 1, the installation position of the cap 7 on the round rod 1 needs to be considered to ensure that the cap 7 can abut against the spacer 3 or the cam piece 2, and can ensure that it can cooperate with the limiting boss 101 to limit and fix the multiple cam pieces 2 and spacers 3 mounted on the round rod 1.

[0029] Furthermore, such as Figure 1 , Figure 2 and Figure 7 As shown, the first positioning rod 4 and the second positioning rod 5 are both provided with a conical portion 401 at one end facing the round rod 1. The upper and lower ends of the round rod 1 are provided with conical grooves 102 that are adapted to the conical portions 401. The first positioning rod 4 and the second positioning rod 5 are both abutted against the upper and lower ends of the round rod 1 through the insertion and engagement of the conical portions 401 and the conical grooves 102. That is, when the first positioning rod 4 abuts against the round rod 1, the conical portion 401 on the first positioning rod 4 is inserted into the conical groove 102 at the lower end of the round rod 1, and the conical portion 401 abuts against the conical groove 102. When the second positioning rod 5 abuts against the round rod 1, the conical portion 401 on the second positioning rod 5 is inserted into the conical groove 102 at the upper end of the round rod 1, and the conical portion 401 abuts against the conical groove 102. By providing the conical portion 401 and the conical groove 102, on the one hand, it facilitates the alignment between the first positioning rod 4 and the round rod 1, and between the second positioning rod 5 and the round rod 1, thereby facilitating the first positioning rod 4 to abut against the round rod 1 and the second positioning rod 5 to abut against the round rod 1; on the other hand, it increases the contact surface to improve stability.

[0030] Furthermore, such as Figure 2 and Figure 6As shown, the positioning plate 6 has a slot 602 at one end facing the round rod 1. The lower part of the round rod 1 has a clamping surface 103 corresponding to the slot 602. There are two clamping surfaces 103, symmetrically arranged, and they are planar. When the positioning plate 6 is engaged with the round rod 1, the lower part of the round rod 1 is located within the slot 602, and the clamping surfaces 103 on both sides of the round rod 1 abut against the groove wall of the slot 602. The clamping surfaces 103 have a certain length along the length direction of the round rod 1, so that the lower end of the round rod 1 can pass through the slot 602 and abut against the first positioning rod 4, and so as to facilitate adjustment of the engagement position of the positioning plate 6 at the lower part of the round rod 1.

[0031] like Figure 1 ,and Figures 3-7 The quenching device also includes a base 8 for mounting on a quenching machine tool. The base 8 has an L-shaped structure. The first positioning rod 4 is vertically mounted on the bottom of the base 8. A first mounting plate 9 is mounted on the inner side wall of the base 8. A second mounting plate 10 is vertically mounted on the first mounting plate 9. The positioning plate 6 is vertically mounted on the second mounting plate 10.

[0032] Furthermore, a first square groove 901 is formed on the outer surface of the first mounting plate 9 corresponding to the position of the second mounting plate 10. The first square groove 901 is vertically arranged and has a certain length. A first square hole 902 is formed at the bottom of the first square groove 901 along the length direction of the first square groove 901. The first square hole 902 penetrates the first mounting plate 9. The length of the first square hole 902 is equal to the length of the first square groove 901, and the width of the first square hole 902 is less than the width of the first square groove 901. One end of the second mounting plate 10 protrudes outward with a first square hole 902 that matches the first square hole 902. The first protrusion 1001 has a width and thickness smaller than the width and thickness of the second mounting plate 10. One end of the second mounting plate 10 abuts against the outer surface of the first mounting plate 9. The thickness of the second mounting plate 10 is greater than the width of the first square hole 902, and the width of the second mounting plate 10 is less than the length of the first square hole 902. The first protrusion 1001 extends into the first square groove 901 after passing through the first square hole 902. The first bolt 11 is provided in the first square groove 901. The first bolt 11 passes through the first square hole 902 and is threadedly connected to the second mounting plate 10.

[0033] like Figure 4 As shown, by setting the first protrusion 1001, the first protrusion 1001 passes through the first square hole 902 and extends into the first square groove 901 to initially fix the second mounting plate 10, assisting in the installation of the second mounting plate 10 and facilitating the screwing of the first bolt 11 onto the second mounting plate 10; at the same time, by changing the position of the first protrusion 1001 in the first square groove 901, the upper and lower positions of the second mounting plate 10 are adjusted, thereby adjusting the upper and lower positions of the positioning plate 6, and by adjusting the upper and lower positions of the positioning plate 6, the snap-fit ​​position of the positioning plate 6 at the lower part of the round rod 1 is adjusted, thereby improving the stability of the round rod 1.

[0034] Furthermore, the second mounting plate 10 has a second square groove 1002 corresponding to the position of the positioning plate 6. The second square groove 1002 is arranged horizontally and has a certain length. A second square hole 1003 is formed at the bottom of the second square groove 1002 along the length direction of the second square groove 1002. The second square hole 1003 penetrates the second mounting plate 10. The length of the second square hole 1003 is equal to the length of the second square groove 1002, and the width of the second square hole 1003 is less than the width of the second square groove 1002. The positioning plate 6 faces the second mounting plate 10. The end of the positioning plate 6 has a second protrusion 601 that is adapted to the second square hole 1003. The width and thickness of the second protrusion 601 are smaller than the width and thickness of the positioning plate 6. The end of the positioning plate 6 facing the second mounting plate 10 abuts against the inner surface of the second mounting plate 10. The thickness of the positioning plate 6 is greater than the width of the second square hole 1003. The second protrusion 601 extends into the second square groove 1002 after passing through the second square hole 1003. A second bolt is provided in the second square groove 1002. The second bolt passes through the second square hole 1003 and is threaded to the positioning plate 6.

[0035] The connection method between the second mounting plate 10 and the positioning plate 6 can refer to the connection method between the first mounting plate 9 and the second mounting plate 10. By setting the second protrusion 601, which extends into the second square groove 1002 after passing through the second square hole 1003, the positioning plate 6 is initially fixed, assisting in the installation of the positioning plate 6 and facilitating the screwing of the second bolt onto the positioning plate 6. At the same time, by changing the position of the second protrusion 601 in the second square groove 1002, the front and rear positions of the positioning plate 6 can be adjusted, thereby facilitating the alignment of the slot 602 of the positioning plate 6 with the lower part of the round rod 1.

[0036] During quenching, the base 8 is first installed on the quenching machine; then, multiple cam plates 2 and spacers 3 are fitted onto the round rod 1, and then the upper end of the round rod 1 is threaded with a cap 7. The cap 7 and the limiting boss 101 cooperate to limit and fix the cam plates 2 and spacers 3, so that the cam plates 2, spacers 3 and round rod 1 form a whole; then, the round rod 1 is placed vertically on the base 8, so that its lower end abuts against the first positioning rod 4, and its lower part is locked by the positioning plate 6; then, the second positioning rod 5 is moved to the upper end of the round rod 1 and abuts against the upper end of the round rod 1.

[0037] It should be noted that the second positioning rod 5 is used to abut the upper end of the round rod 1. The structural design of the drive mechanism that drives the second positioning rod 5 to move and makes the second positioning rod 5 continuously abut the round rod 1 is not an improvement of the quenching device in this embodiment. The drive mechanism can be an existing robotic arm or a drive device that includes a gripper, a motor and a cylinder. The structure of the drive mechanism is not unique. Any drive mechanism that can move the second positioning rod 5 to the round rod 1 and continuously abut the upper end of the round rod 1 is acceptable. At the same time, the parts near the open flame are coated with a high-temperature resistant coating and a flame-retardant coating, and the motor and cylinder are set away from the open flame.

[0038] 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.
