Description

Technical Field

[0001] This utility model relates to the field of electric energy meter casing processing technology, and in particular to a positioning fixture for processing electric energy meter casings. Background Technology

[0002] The meter casing, as the external enclosure of the electricity meter, protects the internal circuitry and measuring mechanisms from external environmental interference and damage. During manufacturing, the meter casing requires positioning fixtures to ensure precise and stable clamping during processing or assembly, thereby improving manufacturing accuracy and efficiency.

[0003] During long-term use, the clamping surfaces of positioning fixtures will gradually wear down. When the clamping surfaces are severely worn, the entire clamping plate needs to be replaced, which increases the maintenance cost of the positioning fixture. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for processing electric meter casings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for processing an electric meter casing includes a fixture base with a lead screw groove. Movable seats are movably arranged on both sides of the top of the lead screw groove on the fixture base, and each movable seat is equipped with a detachable clamping surface. Multiple mounting posts are fixedly arranged on the clamping surface. Each movable seat has a mounting cavity adapted to fit the mounting post. Multiple vertical cavities are formed downward from the top of the movable seat, and each vertical cavity is inserted with a detachable limiting post.

[0007] Furthermore, in a preferred configuration, each mounting post has a vertically penetrating limiting cavity, and the limiting cavity is adapted to the limiting post.

[0008] Furthermore, in a preferred configuration, all the vertical cavities pass through the mounting cavity, and all the vertical cavities are adapted to the limiting post.

[0009] Furthermore, a preferred configuration is that when the mounting post is fully inserted into the mounting cavity, the limiting cavity and the upright cavity are adapted and aligned.

[0010] In addition, in a preferred configuration, the top of each limiting post is connected to a horizontal plate, and the horizontal plate is fitted with multiple screws.

[0011] In addition, in a preferred configuration, each screw on the horizontal plate has a through hole, and each movable seat has a screw hole below the through hole, and the screw holes are adapted to the screws.

[0012] The beneficial effects of this utility model are as follows: the movable seat and the clamping surface are detachable modular designs. The clamping surface is assembled on the movable seat through the limiting post and the mounting post. When the clamping surface is severely worn, only the clamping surface needs to be replaced, without replacing the entire clamping plate, thus saving the maintenance cost of this device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5 A positioning fixture for processing an electric meter casing includes a fixture base 1, on which a lead screw groove 11 is formed. Movable seats 2 are movably arranged on both sides of the top of the lead screw groove 11 on the fixture base 1, and each movable seat 2 is equipped with a detachable clamping surface 3. Multiple mounting posts 31 are fixedly arranged on the clamping surface 3. Each movable seat 2 has a mounting cavity 21 corresponding to the mounting posts 31. Multiple vertical cavities 22 are formed downwards from the top of the movable seat 2, and each vertical cavity 22 is fitted with a detachable limiting post 42.

[0021] A bidirectional lead screw is rotatably mounted within the lead screw groove 11, and the bidirectional lead screw is driven to rotate by a motor. Lead screw pairs are movably mounted on both sides of the bidirectional lead screw, and movable seats 2 are fixedly mounted above the lead screw pairs. The motor drives the bidirectional lead screw to rotate, which in turn moves the lead screw pairs on both sides, thereby moving the movable seats 2 on both sides. It is worth noting that the specific structure and operation of the bidirectional lead screw and lead screw pairs within the lead screw groove 11 are existing technologies and are not part of the main technical problems to be solved in this technical solution; therefore, they will not be elaborated upon in this technical solution.

[0022] Each of the mounting posts 31 has a vertically penetrating limiting cavity 32, and the limiting cavity 32 is adapted to the limiting post 42.

[0023] All vertical cavities 22 pass through the mounting cavity 21, and all vertical cavities 22 are adapted to the limiting post 42. When the mounting post 31 is fully inserted into the mounting cavity 21, the limiting cavity 32 and the vertical cavity 22 are aligned and adapted. By simultaneously inserting the limiting post 42 into both the vertical cavity 22 and the limiting cavity 32, the mounting post 31 can be fixed in the mounting cavity 21, thereby achieving the fixed installation of the clamping surface 3.

[0024] The top of each limiting post 42 is connected to the horizontal plate 4, and the horizontal plate 4 is equipped with multiple screws 5. Each screw 5 has a corresponding through hole 41 on the horizontal plate 4, and each movable seat 2 has a screw hole 23 below the through hole 41, with the screw holes 23 fitting the screws 5. By passing the screws 5 through the through holes 41 and inserting them into the screw holes 23, the horizontal plate 4 can be fixedly installed above the movable seat 2, thereby fixing the limiting post 42.

[0025] In this embodiment, the rotation of the bidirectional lead screw in the lead screw groove 11 can drive the movable seats 2 on both sides and the clamping surface 3 to move, thereby achieving the clamping of the power meter casing and realizing the positioning and processing of the power meter casing. This is prior art, so it will not be described in detail.

[0026] Furthermore, by setting the movable seat 2 and the clamping surface 3 as a detachable modular design, when the clamping surface 3 is severely worn, the user only needs to remove the clamping surface 3 from the movable seat 2, without having to replace the entire clamping plate, thus saving on the maintenance costs of this device.

[0027] Furthermore, when the user needs to remove the clamping surface 3 from the movable seat 2, simply unscrew the screw 5 and then remove the horizontal plate 4 upwards. This will release the locking of the limiting post 42 onto the limiting cavity 32, allowing the user to directly remove the clamping surface 3.

[0028] Next, the user simply inserts the mounting post 31 on the new clamping surface 3 into the mounting cavity 21 on the movable seat 2. At this time, the limiting cavities 32 on the mounting post 31 are aligned with the vertical cavity 22. Then, the user simply installs the horizontal plate 4 above the movable seat 2. The limiting post 42 can then be inserted into both the vertical cavity 22 and the limiting cavity 32, thus fixing the mounting post 31 by engaging the limiting cavity 32 with the limiting post 42. Finally, the user simply passes the screw 5 through the through hole 41 and inserts it into the screw hole 23, thus fixing the horizontal plate 4 and securing the limiting post 32. This completes the installation of the clamping surface 3.

[0029] In this invention, the movable seat 2 and the clamping surface 3 are detachable modular designs. The clamping surface 3 is assembled on the movable seat 2 by the limiting post 42 and the mounting post 31. When the clamping surface 3 is severely worn, only the clamping surface 3 needs to be replaced, without replacing the entire clamping plate, thus saving the maintenance cost of this device.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
