Description

Technical Field

[0001] This utility model relates to the field of metal casing drilling technology, specifically to a fixing fixture for drilling holes in the production of solar inverter casings. Background Technology

[0002] The main function of a solar inverter is to convert the direct current (DC) power from a battery into alternating current (AC). When a solar photovoltaic inverter is in use, its internal modules generate a significant amount of heat. Therefore, its casing is made of metal plates. After the casing is manufactured, mounting holes need to be drilled at corresponding locations on the casing to install the various modules within the inverter. Currently, the drilling process for the casing is primarily carried out using drilling machines or manually. When using a drilling machine, the large size and weight of the metal casing makes it inconvenient to handle, and the numerous and varied drilling positions make it difficult to achieve high drilling efficiency. Therefore, manual drilling is often used to improve flexibility. However, manual drilling can cause casing vibration when drilling through metal plates, leading to deviations in the drilling positions and resulting in low precision in the mounting positions of the internal modules.

[0017] 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.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a fixing fixture for drilling holes in the production of solar inverter housing, including a base and a limiting mechanism set on the base. The limiting mechanism 2 includes a plate 20 movably set on the base 1. A bidirectional lead screw 21 is rotatably connected inside the plate 20. Movable plates 22 are threaded onto the opposite threads at both ends of the bidirectional lead screw 21. A clamping block 23 is fixedly connected to one side of the movable plate 22. In order to allow the solar controller housing to be placed between the two clamping blocks 23, the two movable plates 22 can be driven to move closer to each other by rotating the bidirectional lead screw 21 counterclockwise, so that the clamping block 23 can clamp the solar controller housing under the action of the movable plate 22. At the same time, in order to avoid the clamping block 23 causing clamping damage to the housing, rubber pads 204 are evenly fixedly connected to the inner side of the clamping block 23.

[0019] A rod 205 is slidably connected inside the movable plate 22. One end of the rod 205 is fixedly connected to the plate 20. A driven gear 24 is fixedly connected to the bidirectional lead screw 21. A bolt 27 is threadedly connected to one side of the plate 20 through a connecting block 26. A positioning gear 25 is rotatably connected to one end of the bolt 27. One side of the positioning gear 25 is movably connected to the plate 20. A driving device is provided at one end of the bidirectional lead screw 21, which drives the bidirectional lead screw 21 to rotate forward or backward.

[0020] In practical applications, the driving device is a throttle 201, which allows for manual clamping and loosening of the housing.

[0021] In addition, during assembly line production, the drive device can be configured as a motor and a reducer that work together. The output end of the reducer is connected to the bidirectional lead screw 21, and a controller is set on the motor. The controller controls the motor to rotate forward or backward, thereby driving the bidirectional lead screw 21 to rotate forward or backward, thus achieving the clamping and loosening of the housing.

[0022] In order to reduce the rotational load on the bidirectional lead screw 21 and facilitate the overall movement of the limiting mechanism 2 on the base 1, thereby facilitating the position adjustment of the solar controller housing during grinding, a baffle 202 is fixedly connected to one end of the rod 205 away from the plate 20. One side of the baffle 202 is rotatably connected to the bidirectional lead screw 21 through a bearing. In order to facilitate the overall pulling of the limiting mechanism 2, a handle 203 is fixedly connected to one side of the baffle 202.

[0023] The bottom of both the baffle 202 and the plate 20 is fixedly connected to a movable block 11, and the top of the base 1 is provided with a slide rail 10. The bottom of the movable block 11 is slidably connected to the slide rail 10.

[0024] In order to enable the positioning gear 25 to maintain a smooth linear movement under the action of the bolt 27, a first sliding groove 28 is provided on one side of the plate 20. A first slider 29 is slidably connected to the inner side wall of the first sliding groove 28, and one side of the first slider 29 is fixedly connected to the positioning gear 25.

[0025] With this technical solution, when the solar controller housing is placed between the two clamping blocks 23, the two movable plates 22 can be driven to move closer to each other by rotating the bidirectional lead screw 21 counterclockwise. This allows the clamping blocks 23 to clamp the solar controller housing under the action of the movable plates 22. Furthermore, by tightening the bolts 27, the positioning gear 25 can be driven to mesh with the driven gear 24, thereby enabling the clamping blocks 23 to maintain a stable clamping state.

[0026] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
