[0002] Tappets are a key component in an engine. Their function is to transmit the thrust of the camshaft to the pushrod or valve stem and to withstand the lateral forces exerted by the camshaft during rotation. Therefore, the hardness and wear resistance of the contact area between the tappet and the camshaft are particularly critical. To improve the hardness of the tappet ball joint, it is necessary to perform a hardening treatment on the tappet ball joint.

[0003] Existing quenching equipment can only load one workpiece at a time, resulting in low quenching efficiency and failing to meet production needs.

[0004] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0023] 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.

[0024] Example: A dual-station quenching device for tappets and sockets, such as... Figures 1-6 As shown, the system includes a base 1, with two sets of protective covers 2 installed on one side of the base 1. The protective covers 2 have an umbrella-shaped structure. The upper part of the protective cover 2 is located above the base 1 and is equipped with a positioning seat 17. The positioning seat 17 is used to load the tappet ball socket. The lower part of the protective cover 2 passes through the base 1 and extends to the bottom of the base 1. Gears 3 are installed on the lower part of the protective cover 2, and the two sets of gears 3 mesh with each other. A first synchronous pulley 4 is installed on the lower part of one set of protective covers 2, and a second synchronous pulley 5 is provided on the lower side of the other side of the base 1. The first synchronous pulley 4 and the second synchronous pulley 5 mesh together with the synchronous belt 6.

[0025] In use, the two sets of tappet ball sockets are placed in the two sets of positioning seats 17 respectively, and then the second synchronous wheel 5 is driven to rotate. The second synchronous wheel 5 drives the first synchronous wheel 4 to rotate through the synchronous belt 6. Since the first synchronous wheel 4 is installed on the protective cover 2 through a key connection, the protective cover 2 rotates with the first synchronous wheel 4. At the same time, since the two sets of gears 3 are meshed, the other set of protective covers 2 also rotates with the first synchronous wheel 4. This makes the two sets of positioning seats 17 installed on the upper part of the two sets of protective covers 2 rotate synchronously, so as to realize the simultaneous quenching operation of the two sets of tappet ball sockets, that is, the dual-station quenching operation of tappet ball sockets, which improves the quenching efficiency.

[0026] Preferably, the second synchronous pulley 5 is driven to rotate by a driver, which can be a motor. The output end of the motor is connected to a coupling, and the second synchronous pulley 5 is connected through the coupling.

[0027] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, a tensioning wheel 7 for adjusting the tension of the synchronous belt 6 is provided below the base 1. A bolt 8 is mounted on the tensioning wheel 7, passing through it. The tensioning wheel 7 can rotate around the bolt 8 as an axis. A first oblong hole 9 is provided on the base 1 corresponding to the position of the bolt 8. The end of the bolt 8 passes through the first oblong hole 9 and extends to the top of the base 1. By changing the position of the end of the bolt 8 within the first oblong hole 9, the position of the tensioning wheel 7 is adjusted, thereby adjusting the tension of the synchronous belt 6.

[0028] Preferably, the upper surface of the base 1 is provided with an adjusting plate 10, and the end of the bolt 8 passes through the adjusting plate 10 and is threaded to the nut 11. The bolt 8 is driven to move by pushing or pulling the adjusting plate 10, and the tension wheel 7 is moved by the bolt 8 to change the position of the tension wheel 7.

[0029] Preferably, threaded holes 12 are provided on both sides of the first oblong hole 9 on the base 1, and second oblong holes 13 are provided on both sides of the adjusting plate 10, with the second oblong holes 13 corresponding to the threaded holes 12. The adjusting plate 10 is fixed to the base plate by means of bolts 8 passing through the second oblong holes 13 and threadedly connecting to the threaded holes 12, thereby achieving the limiting of the tensioning wheel 7.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a base 14 is installed on the base 1 corresponding to the position of the protective cover 2. The lower part of the protective cover 2 passes through the base 14 and is rotatably connected to the base 14. By setting the base 14, the protective cover 2 is supported on the one hand, and the protective cover 2 is mounted on the base 1 through the base 14; on the other hand, the base 14 is used to constrain the rotation of the protective cover 2, so that the protective cover 2 can rotate around its axis.

[0031] The base 14 includes a cylindrical part 141, which is a hollow cylindrical structure with one end open and the other end closed. The lower part of the protective cover 2 is provided through the cylindrical part 141. The open end of the cylindrical part 141 is provided with a supporting outer ring 142. The supporting outer ring 142 is integrated with the cylindrical part 141 and is coaxially arranged with the cylindrical part 141. The supporting outer ring 142 is a ring structure. The supporting outer ring 142 is fixedly installed on the base 1 by means of bolts 8 passing through the supporting outer ring 142 and threadedly connecting to the base 1, thereby restricting the cylindrical part 141 on the base 1 and providing a through-hole arrangement.

[0032] A ball bearing 143 is installed inside the cylindrical body 141. The closed end of the cylindrical body 141 supports the ball bearing 143. The inner ring of the ball bearing 143 is installed at the lower part of the protective cover 2. The fit between the inner ring of the ball bearing 143 and the lower part of the protective cover 2 is based on a hole-basis system, and the fit between the outer ring of the ball bearing 143 and the cylindrical body 141 is based on a shaft-basis system.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, a locking ring 15 is threadedly connected to the lower part of the protective cover 2. The locking ring 15 is located below the gear 3 and abuts against the gear 3. By setting the locking ring 15, the gear 3 is fixed to the lower part of the protective cover 2, thereby allowing the gear 3 to rotate with the protective cover 2.

[0034] Preferably, the locking ring 15 has multiple threaded holes 12, which are connected to the inner cavity of the locking ring 15. Bolts 8 are threaded into the threaded holes 12, and the locking ring 15 is fixed by the end of the bolts 8 abutting against the lower part of the protective cover 2, thereby strengthening the limiting of the gear 3.

[0035] As a preferred option, such as Figures 1-3 As shown, another set of protective covers 2 is equipped with a fixed wheel 16 at the position corresponding to the first synchronous wheel 4. The fixed wheel 16 is installed on the protective cover 2 by a key connection. By setting the fixed wheel 16, the gear 3 on the protective cover 2 can be limited.

[0036] 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.
