Description

Technical Field

[0001] The utility model relates to the technical field of fin tube processing, in particular to an automatic replacement device for threaded blades used in fin tube operations. Background Art

[0002] In the fin tube processing technology, tools are set on both the inside and outside of the fin tube. In general, after using 30 to 50 fin tubes, the tool inside the tube needs to be adjusted to avoid wear of the tool inside the tube and resulting in substandard processing of the subsequent fin tubes. The current practice is to use manual adjustment, which is time-consuming and labor-intensive. In addition, the displacement distance is either too much adjustment, resulting in waste of tools, or too little adjustment, resulting in substandard processing of the tube. Summary of the Invention

[0003] The utility model aims to provide a fin tube internal thread cutting edge automatic replacement device which has a simple structure and saves time and effort.

[0005] Preferably, the motor is fixed on the rear support.

[0006] Preferably, the motor is fixed to the support platform.

[0007] Preferably, the motor is a servo motor.

[0008] Preferably, an encoder is installed on the motor.

[0009] Preferably, a coupling is provided between the screw rod and the motor.

[0010] Preferably, the coupling is installed inside the rear support.

[0011] Preferably, the length of the screw rod is less than 2 meters.

[0012] Compared with the prior art, the utility model has the following significant advantages: the technical solution of the utility model has a simple structure, saves time and labor, improves work efficiency, increases the yield rate, and reduces the cost of tool use.

[0013] The present invention is described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 The utility model is a structural schematic diagram of an automatic replacement device for thread cutting blades in finned tubes. DETAILED DESCRIPTION Example

[0015] like Figure 1 As shown, a device for automatically replacing threaded blades for working inside finned tubes comprises a support platform 1, a front support 2 and a rear support 3 are installed on the support platform 1, a guide rail 7 and a screw rod 9 are installed between the front support 2 and the rear support 3, a movable seat 6 is installed on the guide rail 7 and the screw rod 9, a guide rod 8 is installed on the movable seat 6, a threaded cutter head 10 for working inside the finned tube is installed on the end of the guide rod 8, the screw rod 9 is connected to the servo motor 5 through the rear support 3, the servo motor 5 is fixed on the rear support 3, a coupling 4 is provided between the screw rod 9 and the servo motor 5, the coupling 4 is installed inside the rear support 3, and the length of the screw rod 9 is less than 2 meters.

[0016] Working principle: When the blade used on the thread cutter head 10 for finned tube internal operation is worn out, it is usually set to process 30 finned tubes before the blade used on the thread cutter head 10 for finned tube internal operation reaches the switching standard. The servo motor 5 is started, driving the coupling 4 to drive the screw 9 to rotate. Under the action of the guide rail 7, the movable seat 6 moves to the left, so that the thread cutter head 10 for finned tube internal operation switches to the unworn blade, and then the finned tube internal operation is continued. The distance the thread cutter head 10 moves each time is preset in advance by the servo motor 5. The structure of the technical solution of the utility model is very simple, with the advantages of saving time and labor, improving work efficiency, increasing the yield rate, and reducing the cost of tool use.

[0017] In addition to the above-mentioned embodiments, other undescribed implementation methods should also be within the scope of protection of the present invention. The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art of the present invention may make various modifications or additions to the described specific embodiments or replace them in a similar manner, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
