Description

Technical Field

[0001] The utility model relates to the technical field of converter housing production, in particular to a converter housing marking machine. Background Art

[0002] A frequency converter, also known as a current converter, is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. During the production process of the frequency converter, a unique mark will be engraved on the surface of the casing using a marking machine.

[0003] Existing marking machines are generally divided into three types: pneumatic, laser, and electro-erosion. Most marking machines are in a fixed position when marking the inverter housing, and it is difficult to change their position to mark different positions of the inverter housing. Therefore, it is necessary to add marking machines with different angles to mark different positions of the inverter housing, which will cause certain inconveniences. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the inverter housing marking machine of this embodiment includes a support base 1, and a conveyor belt 3 is installed on the upper end surface of the support base 1. The conveyor belt 3 is a common crawler conveying structure on the market. An external power supply is connected to the inverter housing and placed on the surface of the conveyor belt 3. The inverter housing can be driven by the conveyor belt 3 to move to a certain extent. Two rotating rings 4 are connected to the surface rotation of the support base 1. The rotating ring 4 is a hollow circular ring structure. The size of the hollow circle inside is larger than the size of the inverter housing. A marking machine body 5 is installed at one end of the rotating ring 4, and an infrared sensing device is installed at the lower end of the marking machine body 5. When the inverter housing moves to the bottom of the rotating ring 4, it can be detected by the infrared sensing device. An external rack 8 is installed on the surface of the rotating ring 4. A support frame 2 is installed on the left and right ends of the support base 1. A base 13 is installed together at the lower ends of the two support frames 2. A driving device 10 is installed on the upper end of the base 13, and a driving gear is installed at the output end of the driving device 10 9. The upper end of the driving gear 9 is meshed with the outer rack 8, and the driving gear 9 is driven to rotate by the driving device 10. The driving gear 9 drives the outer rack 8 and the rotating ring 4 to rotate, thereby changing the position and angle of the marking machine body 5, and then marking different positions of the inverter housing. It will be more convenient and quick to use. It should be noted that the infrared sensing device, the conveyor belt 3, the marking machine body 5 and the driving device 10 are all connected to the external control platform. After the infrared sensing device detects the inverter housing, it will transmit a signal to the external control platform. At this time, the control platform will stop running the conveyor belt 3 and start the marking machine body 5 to mark the inverter housing, and according to the different needs of the user, start the driving device 10 to change the position of the marking machine body 5 to mark different positions of the inverter housing. The driving device 10 is a common servo motor on the market, which is connected to an external power supply. A corresponding housing needs to be installed on the outside of the driving device 10 for protection.

[0021] Specifically, the surface of the outer rack 8 is rotatably connected to a ring-shaped protective shell 7, and a plurality of through holes are symmetrically opened near the lower part of the side wall of the protective shell 7. A plurality of support rods 6 are installed between the two support frames 2. The support rods 6 pass through the through holes and are slidably connected to the protective shell 7. The size and number of the support rods 6 are adapted to the size and number of the through holes. By arranging a protective shell 7 on the outside of the rotating ring 4, a plurality of support rods 6 pass through the protective shell 7 to play a certain supporting role. The protective shell 7 covers the outside of the outer rack 8 and can play a certain protective role for the outer rack 8. It should be noted that the plurality of support rods 6 are divided into two groups, and the two groups of support rods 6 are symmetrically arranged with each other, thereby providing a relatively stable support effect for the protective shell 7.

[0022] Furthermore, there is a gap at the lower end of the protective shell 7, and the size of the gap is larger than the size of the driving gear 9. Figure 1 As shown, the notch below the protective shell 7 is the connection point between the driving gear 9 and the external rack 8.

[0023] Furthermore, one end of the driving gear 9 away from the driving device 10 is rotatably connected to the positioning shaft 14, and the other ends of the two positioning shafts 14 are respectively fixedly connected to the side walls of a support frame 2. One end of the driving gear 9 is connected to the driving device 10, and the other end is rotatably connected to the positioning shaft 14. By fixing the positioning shaft 14 to the side wall of the support frame 2, the position of the driving gear 9 can be limited and a certain support effect can be provided.

[0024] Furthermore, an annular guide slider 11 is fixedly installed on the inner ring surface of the rotating ring 4, and two arc-shaped grooves 12 are symmetrically opened on the surface of the support seat 1. The interior of the two arc-shaped grooves 12 is slidingly connected with an annular guide slider 11 respectively. The rotating ring 4 is slidingly connected with the arc-shaped groove 12 through the internally arranged annular guide slider 11, which can limit and guide the rotation trajectory of the rotating ring 4.

[0025] The method of using this embodiment is as follows: by placing the inverter housing to be marked on the surface of the conveyor belt 3, the inverter housing is driven to move by the conveyor belt 3, and when the inverter housing moves to the bottom of the rotating ring 4, the infrared sensing device inside the marking machine body 5 will detect the inverter housing. At this time, the marking machine body 5 will mark the inverter housing, and the driving gear 9 is driven to rotate by the driving device 10. The driving gear 9 drives the outer rack 8 and the rotating ring 4 to rotate, thereby changing the position and angle of the marking machine body 5, and then marking different positions of the inverter housing, which will be more convenient and quick to use.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
