Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil casing production technology, and in particular to a grinding mechanism for producing oil casing couplings. Background Technology
[0002] In the production and processing of oil casing couplings, grinding is a crucial step. However, traditional grinding methods often suffer from inconvenience, low efficiency, and inconsistent grinding quality, severely restricting the production efficiency and product quality of oil casing couplings. Specifically, the design of traditional grinding tools often neglects ergonomic considerations, leading to operator fatigue and discomfort after prolonged use. Furthermore, the lack of sufficient stability and adaptability in the grinding mechanism often makes it difficult to achieve fine grinding of the inner cavity of the oil casing, resulting in defects such as burrs and unevenness at the pipe opening.
[0003] Furthermore, traditional grinding tools often cause direct impact and damage to the inner wall of the oil casing when they come into contact with it, which not only affects the service life and safety of the oil casing, but also increases the scrap rate and cost in the production process. At the same time, the vibration and noise generated during the grinding process also seriously affect the comfort of the working environment and the physical and mental health of the operators. Utility Model Content
[0004] This utility model relates to a grinding mechanism for producing oil casing couplings. By optimizing the design of the grip rod and reinforcing crossbar, it significantly improves operational comfort and stability. Simultaneously, the use of a grinding motor to directly drive the grinding disc rotation achieves efficient power transmission and utilization. More importantly, the mechanism innovatively introduces an elastic support structure of a buffer rod and buffer wheel seat, as well as a guide wheel and waisted grinding roller design, greatly enhancing the adaptability and protection of the grinding mechanism, enabling precise and efficient grinding of the oil casing coupling opening. These improvements not only effectively solve the problems and shortcomings of traditional grinding methods but also significantly improve the production efficiency and product quality of oil casing couplings.
[0005] In a first aspect, this utility model provides a grinding mechanism for producing oil casing couplings, specifically comprising: a grinding motor, grips, a grinding disc, and a grinding head seat; the grinding disc is fixedly connected to the end of the rotating shaft of the grinding motor, and four support arms are distributed in a ring around the edge of the grinding disc, with a grinding head seat fixedly installed on each support arm, and the four grinding head seats are placed in the inner cavity of the oil casing; grips are symmetrically fixedly installed on the outer wall of the housing of the grinding motor, the upper end of the grips is inclined upward towards the grinding disc end, and a transverse reinforcing crossbar is fixedly connected between the upper ends of the left and right grips.
[0006] Optionally, control buttons are provided at both ends of the top of the reinforcing crossbar near the corresponding grips, one control button controls the turning on of the grinding motor and the other control button controls the turning off of the grinding motor.
[0007] Optionally, two parallel buffer rods are vertically slidably mounted on the grinding head seat. A plug is provided at one end of the buffer rod near the center of the grinding disc. A buffer wheel seat is fixedly connected between the other ends of the two buffer rods. A buffer spring is fitted on the buffer rod between the buffer wheel seat and the grinding head seat. A guide wheel is rotatably mounted on the side wall of the buffer wheel seat away from the buffer rod through the wheel seat. The guide wheel is always tangent to the inner cavity side wall at the oil casing pipe opening.
[0008] Optionally, a grinding head is fixedly installed at one end of the buffer wheel seat near the grinding disc along the moving direction of the buffer wheel seat, and a grinding roller is fixedly installed on the grinding head.
[0009] Optionally, the grinding roller has a waisted structure and is tangent to the opening of the oil casing coupling to be ground.
[0010] This utility model provides a grinding mechanism for the production of oil casing couplings, which has the following beneficial effects:
[0011] First, the ingenious combination of the grip and the reinforced crossbar not only improves the comfort and stability of operation, but also significantly enhances the overall stability of the structure, ensuring balance and safety during the grinding process and effectively reducing operational risks.
[0012] Secondly, the grinding motor, as the core power source, directly drives the grinding disc's rotation, achieving efficient power transmission and utilization. The four grinding head holders distributed on the grinding disc extend deep into the oil casing cavity, providing a solid foundation for fine grinding. This layout not only improves grinding efficiency but also ensures comprehensive and uniform grinding, effectively enhancing product quality.
[0013] Of particular note is the elastic support structure formed by the buffer rod and buffer wheel seat inside the grinding head holder, along with the addition of a buffer spring, which greatly enhances the adaptability and protective capabilities of the grinding mechanism. These features allow for fine-tuning according to the shape and hardness of the inner wall of the oil casing, avoiding direct impact and damage to the pipe and ensuring production safety. Simultaneously, this buffering effect makes the grinding process smoother, reduces vibration and noise, and improves the comfort of the working environment.
[0014] Furthermore, the design of the guide roller is a stroke of genius. It not only ensures that the grinding mechanism can perform uniform grinding along the inner wall of the casing nozzle, but also improves grinding precision and efficiency. The waisted structure of the grinding roller perfectly adapts to the shape of the casing coupling nozzle, achieving precise tangential grinding. This design not only enhances the grinding effect but also extends the service life of the grinding roller and reduces production costs. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] Example 1: Please refer to Figures 1 to 4 :
[0030] This utility model proposes a grinding mechanism for the production of oil casing couplings, including: a grinding motor 2, a handle 3, a grinding disc 4, and a grinding head seat 5; the grinding disc 4 is fixedly connected to the end of the rotating shaft of the grinding motor 2, and four support arms are distributed in a ring around the edge of the grinding disc 4. A grinding head seat 5 is fixedly installed on each support arm, and the four grinding head seats 5 are placed in the inner cavity of the oil casing 1; the handles 3 are symmetrically fixedly installed on the outer wall of the housing of the grinding motor 2, and the upper end of the handle 3 is inclined upward towards the end of the grinding disc 4. A transverse reinforcing crossbar 301 is fixedly connected between the upper ends of the two handles 3.
[0031] Among them, control buttons 302 are respectively provided at both ends of the top of the reinforcing crossbar 301 near the corresponding grip bar 3. One control button 302 controls the turning on of the grinding motor 2, and the other control button 302 controls the turning off of the grinding motor 2.
[0032] Two parallel buffer rods 501 are vertically slidably mounted on the grinding head seat 5. One end of the buffer rod 501 near the center of the grinding disc 4 is provided with a plug. A buffer wheel seat 502 is fixedly connected between the other ends of the two buffer rods 501. A buffer spring 503 is fitted on the buffer rod 501 between the buffer wheel seat 502 and the grinding head seat 5. A guide wheel 504 is rotatably mounted on the side wall of the buffer wheel seat 502 away from the buffer rod 501 through the wheel seat. The guide wheel 504 is always tangent to the inner cavity side wall at the oil casing pipe opening.
[0033] Among them, a grinding head 505 is fixedly installed on one end of the buffer wheel seat 502 near the grinding disc 4 along the moving direction of the buffer wheel seat 502, and a grinding roller 506 is fixedly installed on the grinding head 505.
[0034] In Example 2, based on Example 1, the grinding roller 506 has a waisted structure. The grinding roller 506 is tangential to the opening of the oil casing coupling to be ground. As the actual grinding component, the waisted structure of the grinding roller 506 allows it to better adapt to the shape of the oil casing coupling opening, achieving precise tangential grinding. With the rotation of the grinding disc 4 and the feed movement of the grinding head seat 5, the grinding roller 506 gradually removes burrs and uneven parts at the opening.
[0035] The working principle of this embodiment:
[0036] During operation, users can securely control the entire polishing mechanism by holding the symmetrical left and right grips 3. The design of the grips 3 not only takes ergonomics into account for more comfortable operation, but also enhances the structural stability by reinforcing the crossbar 301, ensuring balance and safety during the polishing process.
[0037] When the grinding process needs to be started, the user only needs to touch the control button 302, which immediately activates the grinding motor 2. The grinding motor 2 serves as the power source for the entire mechanism, and its shaft directly drives the grinding disc 4 to rotate. Four support arms are cleverly designed around the edge of the grinding disc 4, and the grinding head seat 5 fixedly installed on each support arm extends into the inner cavity of the oil sleeve 1, preparing for subsequent fine grinding.
[0038] As the grinding disc 4 rotates, the four grinding head seats 5 move synchronously. Inside each grinding head seat 5, two parallel buffer rods 501 connect to the buffer wheel seat 502, forming a flexible support structure. This design allows the grinding mechanism to fine-tune according to the shape and hardness of the inner wall when contacting the oil casing coupling, avoiding direct impact on the oil casing and thus protecting the pipe body from damage. Simultaneously, the presence of the buffer spring 503 further enhances this buffering effect, making the grinding process smoother.
[0039] At the end of the buffer wheel seat 502 furthest from the buffer rod 501, the guide wheel 504 is rotatably mounted via the wheel seat, ensuring that it remains tangent to the inner wall of the oil casing pipe opening. This design not only helps guide the grinding mechanism to perform uniform grinding along the inner wall of the pipe opening, but also improves the precision and efficiency of grinding.
[0040] The grinding roller 506, as the actual grinding component, has a waisted structure that allows it to better adapt to the shape of the oil casing coupling opening, achieving precise tangential grinding. As the grinding disc 4 rotates and the grinding head seat 5 feeds, the grinding roller 506 gradually removes burrs and uneven parts at the pipe opening, achieving the desired grinding effect.

[0043] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.
