Description

Technical Field

[0001] The utility model relates to the technical field of grinding oil pipe thread protectors, in particular to a grinding machine for processing oil pipe thread protectors with a dust collection function. Background Art

[0002] Petroleum pipe thread protectors are caps and bushings used to protect the threads and seals of petroleum pipes during loading, unloading, transportation, and storage. During the production and processing of oil pipe thread protectors, in order to improve product quality and performance, a grinder is required to perform fine surface treatment on the surface of the oil pipe thread protectors through specific grinding and polishing processes to remove burrs, scratches and other defects and achieve the required surface roughness and finish. After grinding, the surface of the oil pipe thread protector becomes smoother and flatter, which helps to improve the overall quality and appearance of the product.

[0003] Existing grinders generate a large amount of dust and powder when grinding petroleum pipe thread protectors. If the grinder does not have a dust collection function, dust will accumulate on the construction site, which not only increases the subsequent cleaning workload, but also workers working in a dusty environment for a long time are prone to inhaling large amounts of dust, posing a threat to their lives and health.

[0004] For example, the template grinding equipment disclosed in the announcement number CN219521609U does not have a dust collection function. The dust and debris generated during the grinding process will be directly discharged into the construction environment, resulting in a decrease in on-site air quality, which not only affects the health of construction workers, but may also cause pollution to the surrounding environment and equipment. In addition, the flying dust and debris generated during the grinding process will interfere with the workers' vision and operation, reduce the accuracy and efficiency of grinding, and workers need to stop frequently to clean the dust, which will extend the construction time.

[0005] Therefore, it is necessary to invent a grinding machine for processing petroleum oil pipe thread protectors with a dust collecting function to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a grinding machine for processing oil pipe thread protectors with a dust collection function, so as to solve the problem that the technology does not have the dust collection function.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinder for processing petroleum oil pipe thread protectors with a dust collection function, comprising a base, a protective cover, a collection box and a fan, a stand fixedly installed on one side above the base, a workbench is provided directly above the base, a protective cover is provided on the outside of the workbench, dust hoppers are provided on the left and right sides of the inside of the protective cover, a collection box is provided inside the base, a fan is provided on one side of the collection box and is located inside the base, and a drawer is slidably installed inside the collection box.

[0008] Preferably, a cylinder is provided above the stand, a support frame is provided below the stand, the top surface of the support frame is connected to the output end of the cylinder, a rotating motor is provided below the support frame, the output end of the rotating motor is connected to a grinding disc, the cylinder can realize the up and down movement of the grinding disc, and the rotating motor drives the grinding disc to rotate to grind the workpiece.

[0009] Preferably, a transparent observation window is provided on the front side wall of the protective cover, and the protective cover is used to protect the operator from being hurt by flying debris. The transparent observation window allows the operator to observe the grinding process without opening the protective cover.

[0010] Preferably, a positioning column is provided at the center position above the workbench, and electric telescopic rods are provided at the front and rear ends above the workbench. The output end of the electric telescopic rod is connected to a splint, and the positioning column is used to support the hollow position of the oil pipe thread protector.

[0011] Preferably, there are two clamping plates, which are arranged on the front and rear sides of the positioning column. The clamping plates driven by the electric telescopic rod together constitute a clamping mechanism for the workpiece, which can stably fix the petroleum pipe thread protector to be processed.

[0012] Preferably, there are two dust hoppers, which are symmetrical with each other about the center of the protective cover. A filter is provided at the inlet end of the dust hopper. The two dust hoppers can ensure that the dust generated during the grinding process is collected from two directions at the same time, and the filter can prevent large particles of impurities and debris from entering the dust collection system.

[0013] Preferably, the outlet ends of the two dust hoppers are connected to dust suction hoses, and the outlet ends of the dust suction hoses are connected to the inlet end of the collection box. The dust suction hoses can ensure that the dust is smoothly sucked into the collection box.

[0014] Preferably, the outlet end of the collecting box is connected to the inlet end of the fan via a connecting pipe, and the collecting box can collect dust in a centralized manner.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. With the protective cover, the grinding disc will descend into the protective cover during grinding, so that the debris and dust generated during the grinding process will be blocked by the protective cover, which helps to limit the dust generated during the grinding process to a smaller range. This not only reduces the possibility of these splashes directly hitting the operator, protecting the operator's personal safety, but also reduces the spread of dust in the workshop, improves the working environment, and reduces the difficulty and cost of cleaning;

[0017] 2. Through the setting of dust hopper, collection box and fan, the dust hopper is set on the left and right sides of the protective cover, which can more comprehensively capture the dust and debris generated during the grinding process, reducing the possibility of dust escaping into the work area. The dust collected by the dust hopper is quickly sucked into the collection box through the suction force of the fan, realizing the rapid collection and centralized treatment of dust.
