When the air tightness of the machine cylinder is detected, the machine cylinder is placed on the placing table 2, the machine cylinder should be aligned with the detection rod 5, one end of the placing table 2, which is away from the detection rod 5, is provided with a baffle for limiting the movement of the machine cylinder, and then the driving assembly is started, so that the driving assembly drives the mounting column 4 and the detection rod 5 to move towards the machine cylinder in the horizontal direction. In the process that the detection rod 5 is inserted into the inner wall of the machine cylinder, since the mounting column 4 is connected to the mounting block 3 through the plurality of springs 6, the mounting column 4 can move within a certain range, so that when the machine cylinder deviates from the detection rod 5, the detection rod 5 cannot be inserted into the predetermined position in the machine cylinder, the sealing performance between the detection rod 5 and the machine cylinder and the detection result are affected, preferably, the spring 6 is a spring with a large elastic coefficient. After the detection rod 5 is inserted into the machine cylinder, the outer wall of the detection rod 5 is tightly attached to the inner wall of the machine cylinder, then compressed air is introduced into the air inlet channel of the detection rod 5, if the machine cylinder does not leak and the expansion block of the machine cylinder contracts normally, it indicates that the detection is qualified, and the machine cylinder can be used, otherwise, the machine cylinder needs to be repaired, in the embodiment, the mounting column 4 and the detection rod 5 are integrally connected, and a through hole, which is in communication with the air inlet channel, is formed in the mounting column 4. Through the device, the worker only needs to place the machine cylinder on the placing table 2 and start the driving assembly, so that the detection rod 5 can be quickly inserted into the machine cylinder and the air tightness of the machine cylinder can be detected by introducing compressed air, the environment after the machine cylinder is assembled with the main shaft of the wire drawing machine is simulated, the air tightness detection effect is completely consistent with the detection when the machine cylinder is assembled with the main shaft of the wire drawing machine, and the machine cylinder can be quickly repaired when the air tightness is unqualified, so that the machine cylinder does not need to be disassembled and assembled for multiple times, and the work efficiency is improved. As a preferred embodiment, a lifting groove is formed in the base 1, a hydraulic cylinder is fixedly arranged in the lifting groove, the output end of the hydraulic cylinder is fixed to the bottom of the placing table 2, the placing table 2 is driven to be raised or lowered by the hydraulic cylinder, so that the horizontal height of the machine cylinder is changed, the machine cylinder of different sizes can be accommodated, and the machine cylinder can be conveniently taken off from the placing table 2. As a preferred embodiment, a bandage is arranged on one side of the placing table 2.
[0021] As Figure 1 , Figure 4 , Figure 5As shown, further, the two ends of each arc-shaped plate 7 are provided with a first limiting plate 8 for limiting the sliding of the mounting column 4 on the arc-shaped plate 7. In the present embodiment, the connection between the mounting column 4 and the detection rod 5 has an annular groove, which facilitates the abutment of the first limiting plate 8 with the side wall of the mounting column 4. Four mounting grooves are formed in the inner wall of the cavity of the mounting block 3, and each mounting groove is provided with a spring 6. When the mounting block 3 drives the mounting column 4 to move so that the detection rod 5 is inserted into the barrel, the barrel gives the mounting column 4 a counterforce, which pushes the mounting column 4 to move away from the barrel (affected by the elastic coefficient of the spring 6, if the spring 6 pushes the arc-shaped plate 7 to clamp the mounting column 4 very tightly, the mounting column 4 will not move). The first limiting plate 8 can limit the movement of the mounting column 4.
[0022] As shown in Figure 1 , Figure 4 , Figure 5 As shown, further, the two side walls of the mounting block 3 are each provided with a second limiting plate 9 for limiting the extension of the first limiting plate 8 from the cavity of the mounting block 3. In order to further limit the movement of the mounting column 4 away from the barrel after being subjected to the counterforce, the second limiting plate 9 is fixed to the mounting block 3 by being arranged on the two sides of the mounting block 3, thereby limiting the maximum stroke of the movement of the mounting column 4 relative to the mounting block 3.
[0023] As shown in Figures 1 to 4 , further, the driving assembly comprises a mounting plate 10 fixedly arranged on one side of the mounting block 3, a motor 11 fixedly arranged on the mounting plate 10, a gear 12 fixedly arranged on the output end of the motor 11 and vertically downwardly penetrating through the mounting plate 10, and a rack 13 fixedly arranged on the side wall of the base 1 and engaged with the gear 12. When the mounting block 3 is driven to move, the motor 11 is started to drive the gear 12 to rotate. Since the gear 12 is engaged with the rack 13, the mounting block 3 is driven by the gear 12 to move along the length direction of the base 1, so that the mounting block 3 drives the mounting column 4 and the detection rod 5 to move toward the barrel. After the detection is completed, the motor 11 is reversely rotated to return the mounting block 3 to the zero position.
[0024] As shown in Figure 4 , further, the bottom of the mounting block 3 is fixedly provided with a T-shaped block 14, and the top of the base 1 is provided with a sliding groove matched with the T-shaped block 14. The sliding cooperation between the T-shaped block 14 and the sliding groove stabilizes the movement of the mounting block 3 and guides the movement of the mounting block 3.
[0025] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5As shown in the figure, further, the two ends of the detection rod 5 are provided with sealing grooves along the radial direction thereof, and a sealing ring 15 is embedded in each sealing groove. The two ends of the detection rod 5 are embedded with the sealing ring 15 through the sealing grooves, which ensures the sealing between the detection rod 5 and the inner wall of the cylinder, simulates the environment after the assembly of the cylinder and the main shaft of the drawing machine, and ensures the accuracy of the detection result.
[0026] As shown in the figure, Figure 2 , Figure 3 , Figure 5 As shown in the figure, further, the end of the detection rod 5 facing the placement table 2 is provided with a guide inclined surface 16. The guide inclined surface 16 guides the insertion of the detection rod 5 into the cylinder, so that after the cylinder is placed on the placement table 2 and a small amount of deviation occurs, the detection rod 5 can be accurately inserted into the cylinder.
[0027] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
