Description

Technical Field

[0001] This utility model relates to the field of rock drilling tool manufacturing, and in particular to a novel tooling for shot blasting drill rods. Background Technology

[0002] In the production process of drill bits, shot blasting is involved in the production of friction-welded drill rods.

[0003] However, because friction-welded drill rods have welded edges at the friction-welded parts, the friction-welded edge area inside the core hole can trap the steel shot sprayed during shot blasting, leaving it in the welding area of ​​the drill rod core hole. During production, both the shot blasting and packaging processes require high-pressure airflow to clean the drill rod core hole to remove the residual steel shot. However, due to the friction-welded edge structure of the drill rod, the cleaning efficiency is low and the effect is poor. This results in a risk that steel shot may fall out of the core hole during use, affecting the fit of the drill rod threads, and may even fall into the rock drill, causing wear or damage to the rock drill.

[0004] Therefore, it is necessary to provide a new type of tooling for shot blasting of drill rods to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] First Embodiment

[0023] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a novel tooling for shot blasting of drill rods provided by this utility model; Figure 2 for Figure 1The diagram shows the installation structure. A novel tooling for shot blasting of drill rods includes: a sealing rod 1, wherein a plurality of sealing rings 11 are fitted on the outer side of the sealing rod 1;

[0024] Extension component 2, which is disposed on the top of the sealing rod 1;

[0025] Handhold 3, which is disposed on the top of the extension component 2.

[0026] The number of sealing rings 11 is three.

[0027] The working principle of the novel tooling for shot blasting of drill rods provided by this utility model is as follows:

[0028] When in use, the sealing rod 1 with the sealing ring 11 is inserted into the openings at both ends of the drill rod to block the openings at both ends of the drill rod and prevent steel shot from entering the inside of the drill rod when polishing it.

[0029] Compared with related technologies, the novel tooling for shot blasting of drill rods provided by this utility model has the following beneficial effects:

[0030] By inserting the sealing rod 1, which is fitted with a sealing ring 11, into the inside of the drill rod, the opening of the drill rod is blocked, which facilitates the operation of the user and has a good blocking effect. During use, it can ensure that steel shot cannot enter the core hole of the drill rod, effectively avoiding the risks caused by steel shot residue. At the same time, it also reduces the blowing burden of the shot blasting and packaging processes, achieving the effect of saving time and improving production efficiency.

[0031] Second Embodiment

[0032] Please refer to the following: Figure 3 Based on the first embodiment of this application, which provides a novel tooling for shot blasting of drill rods, the second embodiment of this application proposes another novel tooling for shot blasting of drill rods. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0033] Specifically, the second embodiment of this application provides a novel tooling for shot blasting of drill rods, which differs in that the extension assembly 2 includes an extension rod 21, a first threaded hole 22, a first threaded rod 23, a connector 24, a second threaded hole 25, a mounting head 26, and a second threaded rod 27. The mounting head 26 is fixedly installed at the bottom of the handheld part 3, the connector 24 is fixedly installed at the top of the sealing rod 1, and the extension rod 21 is disposed between the connector 24 and the mounting head 26.

[0034] The first threaded hole 22 is formed at the top of the extension rod 21, and the second threaded rod 27 is threaded to the inner side of the first threaded hole 22.

[0035] The second threaded hole 25 is opened at the top of the connector 24, and the first threaded rod 23 is threaded to the inner side of the second threaded hole 25.

[0036] The top of the first threaded rod 23 and the bottom of the extension rod 21 are fixedly installed.

[0037] The top of the second threaded rod 27 and the bottom of the mounting head 26 are fixedly installed.

[0038] Please see Figure 2 This is a schematic diagram of the sealing rod 1 being inserted into the drill rod. By fitting a sealing ring 11 on the outer side of the sealing rod 1, the stability of the sealing rod 1 after it is inserted into the drill rod can be increased.

[0039] The sealing ring 11 is made of rubber. When it is squeezed during use, it can deform, so that the outer side of the sealing ring 11 presses against the inside of the drill rod, thereby playing an anti-slip role and preventing the sealing rod 1 from falling off.

[0040] The working principle of the novel tooling for shot blasting of drill rods provided by this utility model is as follows:

[0041] When in use, when it is necessary to insert to different depths and block the inside of the drill rod, the user can selectively install and remove the extension rod 21.

[0042] When installing the extension rod 21, place the extension rod 21 between the mounting head 26 and the connector head 24, then thread the first threaded rod 23 to the inner side of the second threaded hole 25, and thread the second threaded rod 27 to the inner side of the first threaded hole 22, thereby installing the extension rod 21 to the mounting head 26 and the connector head 24 respectively, increasing the length of the tooling.

[0043] When disassembling the extension rod 21, simply thread the first threaded rod 23 out from the inner side of the second threaded hole 25, thread the second threaded rod 27 out from the inner side of the first threaded hole 22, and then thread the second threaded rod 27 to the inner side of the second threaded hole 25 to install the mounting head 26 and the connecting head 24, thereby shortening the length of the tooling.

[0044] Compared with related technologies, the novel tooling for shot blasting of drill rods provided by this utility model has the following beneficial effects:

[0045] The extension rod 21, the first threaded hole 22, the first threaded rod 23, the connector 24, the second threaded hole 25, the mounting head 26, and the second threaded rod 27 work together to allow the user to install or remove the extension rod 21 during use. This allows for adjustment of the tooling length according to the usage situation, thus increasing the adaptability of the tooling.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
