Description

Technical Field

[0001] This utility model relates to the field of graphite electrode production, specifically a novel graphite electrode connector bolt installation device. Background Technology

[0002] Graphite electrode connector pins are installed on graphite electrode connectors to prevent the connector from detaching from the body. After production, the graphite electrode connector requires the installation of connector pins and is secured with retaining springs. Currently, the main method for installing connector pin retaining springs is by workers using retaining spring pliers. Because retaining springs are relatively thin, using retaining spring pliers is inconvenient and requires a high level of worker skill. Furthermore, the retaining springs are highly elastic and can easily pop out during the clamping process, posing a safety hazard. Moreover, existing installation devices are mostly limited to installing retaining springs of a single specification; when the retaining spring specification changes, the device needs to be replaced, making it impractical. Therefore, those skilled in the art have provided a novel graphite electrode connector pin installation device to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0015] 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. Example

[0016] like Figure 1-2 As shown, the graphite electrode connector bolt installation device of this utility model includes a capacity chamber and a drive section. The capacity chamber is a retaining spring compartment 101, with one end being an extrusion end 1011 and the other end being a capacity end 1012. The inner diameter of the extrusion end 1011 is smaller than the outer diameter of the retaining spring 102 in its natural state, and the outer diameter of the extrusion end 1011 is smaller than the inner diameter of the graphite electrode connector bolt hole. The drive section consists of a drive motor 201, a lead screw 202, a guide rail 203, an end block 204, a slider 205, a housing 301, a battery 302, a forward button 303, and a reverse button 304. A drive motor 201 is mounted on the housing 301. A lead screw 202 is connected to the drive motor 201 and can rotate with it. A slider 205 is threadedly connected to the lead screw 202. A guide rail 203 provides guidance for the slider 205. The ends of the lead screw 202 and the guide rail 203 are connected by end blocks 204, forming a linear motion module. A battery 302 is installed inside the housing 301 to provide power to the device. A forward button 303 and a reverse button 304 are located on the housing 301. A retaining spring holder 101 is detachably connected to the housing 301 via a threaded connection.

[0017] In this embodiment, the taper angle α of the extrusion end 1011 is 20°, and the surface roughness Ra is ≤0.8μm. The front end of the slider 205 is provided with a buffer pad 206, which is made of rigid plastic material and has an internal annular structure. The inner hole of the buffer pad 206 is a stepped hole. One of the stepped holes of the buffer pad is connected to the slider by a thread. Multiple support holes are opened along the circumferential direction on the side wall adjacent to the slider 205 and the buffer pad 206, and a spring 4 is fixedly connected inside the support hole.

[0018] With this setup, different sizes of retaining rings can be installed by replacing the retaining ring compartment 101 and the buffer pad 206, thus expanding the range of applications. In addition, the buffer pad 206 can protect the retaining ring from being scratched during constant pressure installation. Furthermore, both are detachable, making replacement more convenient and quick.

[0019] Before using the device, first remove the retaining spring compartment 101 from the outer casing 301, and install a certain number of retaining springs 102 into the capacity end 1012 of the retaining spring compartment 101. Then press the back button 304 to move the slider 205 back to the root of the lead screw 202, which can store a certain number of retaining springs 102 at a time, avoiding the tedious work of picking them up one by one. Then install the retaining spring compartment 101 containing the retaining springs 102 onto the outer casing 301 through a threaded connection. Next, press the forward button 303 to move the slider 205 forward, compress the retaining springs 102, and push them to the edge of the extrusion end 1011.

[0020] When using the device, insert the extrusion end 1011 into the bolt hole of the graphite electrode connector, press the forward button 303, and under the drive of the drive motor 201, the lead screw 202 rotates, causing the slider 205 to move forward by the thickness of a retaining ring 102, pushing one retaining ring 102 out of the extrusion end 1011, thus completing the installation of the retaining ring 102. Push the device out of the bolt hole of the graphite electrode connector, completing one installation of the retaining ring 102. When it is necessary to install the retaining ring 102 again, repeat the above operation of pressing the forward button 303. After all retaining rings 102 are installed, press and hold the reverse button 304 to return the slider 205 to the root of the lead screw 202, so that the next retaining ring 102 installation operation can be performed.

[0021] In this embodiment, a certain number of snap rings 102 can be stored at once by setting up a capacity compartment, avoiding the tedious work of manually picking up snap rings 102 one by one, reducing the workload. The electric drive method is adopted to realize the automatic ejection and installation of snap rings 102 through the drive part, eliminating the need for manual operation with snap ring 102 clamps, reducing the difficulty of manual operation and requiring low operator skills. During the entire installation process, snap rings 102 move inside the device and are ejected, avoiding the snap rings 102 from popping out during installation, eliminating safety risks. The device is lightweight, easy to operate, and can improve the work efficiency of snap ring 102 installation.

[0022] 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.
