Description

Technical Field

[0001] This utility model relates to the field of positioning tool technology, and in particular to a tool for marking bolts. Background Technology

[0002] The turbine cylinder is one of the core components of a gas turbine. Its main function is to convert the thermal and kinetic energy of high-temperature and high-pressure gas into mechanical energy. It is commonly used in power generation, industrial energy conservation and other technical fields.

[0003] When it is necessary to remove the hot-tightened bolts on the turbine cylinder, in order to avoid damage to the turbine cylinder, it is necessary to first mark the position of the hot-tightened bolts, and then remove them according to the marks. However, the existing marking method is mainly to manually measure and mark the bolts, but this method lacks suitable marking tools, resulting in poor marking accuracy and affecting work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing a tool for marking bolt positions, thereby improving the accuracy of bolt marking and increasing work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a tool for marking bolts, which acts on bolts, including a separable magnetic base and a marking component coaxially disposed on the top of the bolt;

[0006] The marking component consists of a transmission rod rotatably mounted on the top of the magnetic base and a marking assembly mounted on the transmission rod and in contact with the bottom end of the bolt;

[0007] The transmission rod is used to drive the marking assembly to rotate around the axis of the magnetic base, and the actual position is marked by the contact trajectory between the marking assembly and the bottom of the bolt.

[0008] Furthermore, the marking assembly consists of a positioning seat, a connecting rod, and the marking component itself.

[0009] The positioning seat is mounted on the transmission rod and is adapted to the diameter of the bolt.

[0010] The connecting rod is vertically mounted on the positioning seat, and the marking component is mounted at the bottom of the connecting rod. The marking component is in circumferential contact with the bottom end of the bolt sidewall to form a position marking trajectory.

[0011] Furthermore, the connecting rod is provided with a guide groove along its length, and the positioning seat is slidably mounted on the transmission rod;

[0012] The positioning seat is provided with a constraint component, which includes a constraint block and a first screw.

[0013] The constraint block is slidably disposed within the positioning seat and corresponds to the position of the guide groove;

[0014] The first screw is rotatably inserted into the positioning seat and threadedly connected thereto, and its insertion end is rotatably connected to the constraint block. The first screw is used to drive the constraint block to move closer to or further away from the guide groove.

[0015] Furthermore, the marking assembly includes an abutment platform disposed at the bottom of the connecting rod and a marking seat disposed at the bottom of the abutment platform;

[0016] The abutment platform is circumferentially fitted to the side wall of the bolt, and the bottom surface of the marking seat is coplanar with the bottom surface of the bolt to facilitate marking by workers.

[0017] Furthermore, the abutment platform is vertically slidably sleeved on the connecting rod;

[0018] The connecting rod is also provided with a second screw that is threadedly engaged with the abutment platform. The second screw is used to drive the abutment platform to move vertically up and down.

[0019] Furthermore, the magnetic base is also provided with a recording component, which consists of a recording platform and a recording rod;

[0020] The recording platform is coaxially mounted on the top of the magnetic base and located below the connecting rod, and its surface is evenly distributed with angle scale lines around its circumference.

[0021] It also includes a recording rod that is coaxially rotatably mounted on the magnetic base and corresponds to the recording stage. The recording rod and the recording stage form an annular angle measurement system to realize the visual calibration of the rotation angle of the transmission rod.

[0022] The beneficial effects of this utility model are reflected in:

[0023] This invention utilizes the cooperation between a magnetic base and a marking component. After the magnetic base is coaxially set with the bolt, the magnetic force constrains the movement of the magnetic base, thereby positioning the marking component. Subsequently, the operator drives the marking component to rotate around the bolt's axis using a transmission rod, until the marking component rotates to each predetermined angle and marks the bolts sequentially. This improves the marking accuracy and, consequently, the work efficiency. Attached Figure Description

Detailed Implementation

[0029] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-3 This utility model discloses a tool for marking bolts, which is applied to bolt 01. It includes a separable magnetic base 1 and a marking component 2 that are coaxially arranged on the top of bolt 01. The magnetic base 1 is used to position the marking component 2 and make it coaxially arranged with bolt 01.

[0031] The marking component 2 consists of a transmission rod 21 rotatably mounted on the top of the magnetic base 1 and a marking assembly 22 mounted on the transmission rod 21 and in contact with the bottom end of the bolt 01;

[0032] The transmission rod 21 is used to drive the marking assembly 22 to rotate around the axis of the magnetic base 1, and the actual position is marked by the contact trajectory between the marking assembly 22 and the bottom of the bolt 01.

[0033] In practice, when it is necessary to mark the bolt 01, the staff places the magnetic base 1 coaxially on the top of the bolt 01 and makes it adhere to the bolt 01. At this time, the magnetic base 1 is positioned on the bolt 01 by the constraint of the magnetic attraction force. At the same time, the marking component 22 contacts the bottom end of the side wall of the bolt 01. Then, the staff drives the marking component 22 to rotate around the axis of the magnetic base 1 through the transmission rod 21 until the marking component 22 rotates to the predetermined angle, and then the marking is performed.

[0034] In this invention, the magnetic base 1 and the marking component 2 are coupled together. After the magnetic base 1 is coaxially set with the bolt 01, the magnetic force constrains the movement of the magnetic base 1, thereby positioning the marking component 2. Then, the worker drives the marking component 22 to rotate around the bolt 01 axis by the transmission rod 21 until the marking component 22 rotates to each predetermined angle and marks in sequence, thereby improving the marking accuracy and thus improving work efficiency.

[0035] It should be noted that the structure and function of the magnetic base 1 can adopt the existing magnetic base. The structure and function of the magnetic base are common knowledge to those skilled in the art, so they will not be described in detail here.

[0036] In one embodiment, the marking component 22 includes a positioning seat 221 disposed on the transmission rod 21 and adapted to the diameter of the bolt 01. The positioning seat 221 is also vertically provided with a connecting rod 222. The marking component 223 is disposed at the bottom of the connecting rod 222. The marking component 223 is in circumferential contact with the bottom end of the side wall of the bolt 01 to form a position marking track.

[0037] With this design, when the operator rotates the transmission rod 21, the transmission rod 21 drives the marking component 223 to rotate around the axis of the magnetic seat 1 via the connecting rod 222. During the rotation, the marking component 223 is always in contact with the side wall of the bolt 01 to ensure marking accuracy. When the marking component 223 rotates to the predetermined position, the operator can mark the current position.

[0038] In one embodiment, the connecting rod 222 is provided with a guide groove 211 arranged along its length direction, and the positioning seat 221 is slidably disposed on the transmission rod 21;

[0039] The positioning seat 221 is provided with a constraint component 3, which includes a constraint block 31 that is slidably disposed in the positioning seat 221 and corresponds to the position of the guide groove 211. When the constraint block 31 is inserted into the guide groove 211, the constraint block 31 constrains the positioning seat 221 to move.

[0040] It also includes a first screw 32 that is rotatably inserted into and threadedly connected to the positioning seat 221. The insertion end of the first screw 32 is rotatably connected to the constraint block 31. The first screw 32 is used to drive the constraint block 31 to move closer to or further away from the guide groove 211.

[0041] With this design, after the magnetic suction table is coaxially set on the bolt 01, the operator moves the positioning seat 221 until the marking component 223 is in contact with the side wall of the bolt 01, thus accommodating bolts 01 of different diameters. Then, the first screw 32 is rotated to move the constraint block 31 towards the guide groove 211 until the constraint block 31 is inserted into the guide groove 211. At this time, the constraint block 31 moves by constraining the positioning seat 221. When it is necessary to adjust the position of the positioning seat 221, the operator reverses the first screw 32 to make the constraint block 31 exit the guide groove 211.

[0042] In one embodiment, the marking member 223 includes an abutment platform 2231 disposed at the bottom of the connecting rod 222 and a marking seat 2232 disposed at the bottom of the abutment platform 2231;

[0043] The abutment platform 2231 is circumferentially attached to the side wall of the bolt 01, and the bottom surface of the marking seat 2232 is coplanar with the bottom surface of the bolt 01 and has a slot 2233 for easy marking by workers.

[0044] With this design, when the positioning seat 221 moves, the positioning seat 221 drives the abutment platform 2231 to move together through the connecting rod 222 until the abutment platform 2231 contacts the side wall of the bolt 01. At this time, the marking seat 2232 corresponds to the diameter of the bolt 01.

[0045] When the transmission rod 21 rotates, the abutment platform 2231 moves along with it and always contacts the side wall of the bolt 01 until the marking seat 2232 moves to the predetermined position. The staff can mark the actual position of the marking seat 2232 through the slot 2233.

[0046] In one embodiment, the abutment platform 2231 is vertically slidably sleeved on the connecting rod 222;

[0047] The connecting rod 222 is also provided with a second screw 4 that is threadedly engaged with the abutment platform 2231. When the second screw 4 rotates, it is used to drive the abutment platform 2231 to move vertically up and down.

[0048] With this design, when the contact platform 2231 contacts the side wall of the bolt 01, but the marking seat 2232 is not level with the bottom of the bolt 01, the operator can use the second screw 4 to drive the contact platform 2231 to move vertically up and down on the connecting rod 222 until the bottom of the marking seat 2232 corresponds to the bottom of the bolt 01. Then, the positioning seat 221 is used to adapt to bolts 01 of different specifications, further improving applicability.

[0049] In one embodiment, the magnetic base 1 is further provided with a recording component 5, which includes a recording platform 51 coaxially disposed on the top of the magnetic base 1 and located below the connecting rod 222. An angle scale line is provided on the top of the positioning platform.

[0050] It also includes a recording rod 52 that is coaxially rotatably mounted on the magnetic base 1 and corresponds to the recording stage 51. The recording rod 52 and the recording stage 51 form an annular angle measurement system. When the transmission rod 21 rotates, the recording rod 52 rotates together with the transmission rod 21 and records the rotation angle of the transmission rod 21.

[0051] With this design, when the operator rotates the transmission rod 21, the recording rod 52 rotates coaxially with the transmission rod 21 until the transmission rod 21 reaches the predetermined position. The angle indicated by the recording rod 52 is then the actual rotation angle of the transmission rod 21, which is convenient for the operator to observe and adjust.

[0052] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0054] Additionally, "multiple" refers to two or more.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
