Description

Technical Field

[0001] This utility model mainly relates to the field of bolt oiling technology, specifically to a bolt production oiling device. Background Technology

[0002] In the field of machinery manufacturing, bolts, as core connecting components, directly affect the reliability and service life of equipment due to their rust-proof performance. To effectively prevent bolt corrosion during storage, transportation, and operating environments, coating with rust-preventive oil has become a widely adopted protective measure in the industry. With the accelerated advancement of industrial automation, modern manufacturing has placed higher technical demands on the efficiency, uniformity control, and operational stability of bolt oiling processes.

[0003] Traditional bolt oiling processes generally employ manual immersion or simple mechanical stirring. These methods have significant technical shortcomings: manual operation is not only inefficient, but also prone to uneven oiling due to human factors, resulting in large variations in the thickness of the oil film on the bolt surface and consequently inconsistent rust prevention performance. Meanwhile, simple mechanical stirring devices lack a precise motion control system, making it impossible to achieve stable rotation and full contact of the bolts in the oil. Furthermore, the high degree of manual involvement further increases production costs and labor intensity, making them unsuitable for large-scale production. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a bolt production oiling device to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a bolt production oiling device, comprising an oil storage tank for storing rust-preventive oil, a protective cover at the upper end of the oil storage tank, lifting mechanisms symmetrically arranged on the left and right sides of the oil storage tank, a mounting frame between the output ends of the two lifting mechanisms, a rotating mechanism on the mounting frame, and a bolt placement basket on the output end of the rotating mechanism. The lifting mechanism drives the mounting frame to descend, immersing the bolt placement basket in the rust-preventive oil in the oil storage tank, and the rotating mechanism drives the bolt placement basket to rotate.

[0008] Preferably, the lifting mechanism includes a support plate fixed to the outer wall of the oil tank, a hydraulic cylinder is provided on the support plate, and a mounting bracket is fixedly installed between the piston rods of the two hydraulic cylinders.

[0009] Preferably, a guide sleeve is fixedly installed on the support plate, the guide sleeve is disposed on both sides of the hydraulic cylinder, and a guide shaft is fixedly installed on the mounting bracket, the guide shaft being slidably installed inside the guide sleeve.

[0010] Preferably, the mounting frame includes an oil-permeable base, and two upright plates are symmetrically arranged on the upper end of the oil-permeable base. The upright plates are provided with a plurality of oil inlet holes. The upright plates are fixedly connected to the lifting mechanism. The oil-permeable base is a grid.

[0011] Preferably, the rotating mechanism includes a mounting plate fixed on the mounting bracket, a speed reducer fixedly mounted on the mounting plate, the input end of the speed reducer being connected to a motor, the output end of the speed reducer being connected to a rotating shaft, a mounting ring fixedly mounted on the rotating shaft, and a mounting frame fixedly mounted on the mounting ring, the mounting frame being used to mount the bolt placement basket.

[0012] Preferably, the bolt placement basket includes a base, and a grid plate is fixedly installed on each of the four sides of the upper end of the base. A connecting block is fixedly installed on the upper end of the grid plate. The connecting blocks are connected end to end in sequence. The base and one of the connecting blocks are fixed on a connecting frame. Connecting holes are provided at the four corners of the connecting frame. The connecting frame is connected to the mounting frame through screw assemblies and connecting holes.

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0015] This invention's rotating mechanism drives the bolt placement basket to rotate, ensuring the bolts are fully in contact with the rust-preventive oil and guaranteeing a uniform coating of oil on each bolt surface, effectively enhancing their corrosion resistance. This invention can simultaneously accommodate multiple bolts in the bolt placement basket for oiling. Combined with an automated lifting and rotating process driven by a hydraulic cylinder and motor, it significantly reduces manual intervention and dramatically improves the production efficiency of the oiling process. The automated operation mode reduces human error, and the bolt placement basket maintains stable rotation during the process, ensuring consistent oil thickness and uniformity for each batch of bolts, thus improving the reliability of the oiling quality.

[0016] The oil-permeable base of this utility model adopts a grid structure and is designed with an oil inlet hole on the upright plate. When the bolt basket is removed from the oil surface, the excess anti-rust oil can flow back to the oil storage tank through the oil-permeable base and the oil inlet hole. This not only avoids oil waste and reduces production costs, but also reduces oil pollution discharge and has environmental benefits. Attached Figure Description

[0030] See attached document Figures 1-6 A bolt production oiling device includes an oil storage tank 1 for storing rust-preventive oil. The oil storage tank 1 is equipped with a protective cover 2 at its upper end. Lifting mechanisms 3 are symmetrically arranged on the left and right sides of the oil storage tank 1. An installation frame 4 is arranged between the output ends of the two lifting mechanisms 3. A rotating mechanism 5 is arranged on the installation frame 4. A bolt placement basket 6 is arranged on the output end of the rotating mechanism 5. The lifting mechanism 3 drives the installation frame 4 to descend, so that the bolt placement basket 6 is immersed in the rust-preventive oil in the oil storage tank 1. The rotating mechanism 5 drives the bolt placement basket 6 to rotate.

[0031] The lifting mechanism 3 includes a support plate 31 fixed on the outer wall of the oil storage tank 1, a hydraulic cylinder 32 is provided on the support plate 31, and a mounting bracket 4 is fixedly installed between the piston rods of the two hydraulic cylinders 32.

[0032] A guide sleeve 33 is fixedly installed on the support plate 31. The guide sleeve 33 is located on both sides of the hydraulic cylinder 32. A guide shaft 34 is fixedly installed on the mounting bracket 4. The guide shaft 34 is slidably installed inside the guide sleeve 33. The guiding structure of the guide sleeve 33 and the guide shaft 34 ensures that the bolt placement basket is raised and lowered smoothly, avoiding uneven oiling or bolt falling off due to shaking.

[0033] The mounting frame 4 includes an oil-permeable base 42. Two upright plates 41 are symmetrically arranged on the upper end of the oil-permeable base 42. The upright plates 41 have several oil inlet holes 43. The upright plates 41 are fixedly connected to the lifting mechanism 3. The oil-permeable base 42 is a grid.

[0034] The rotating mechanism 5 includes a mounting plate 51 fixed on the mounting bracket 4. A reducer 52 is fixedly mounted on the mounting plate 51. The input end of the reducer 52 is connected to the motor 53, and the output end of the reducer 52 is connected to the rotating shaft 54. A mounting ring 55 is fixedly mounted on the rotating shaft 54, and a mounting frame 56 is fixedly provided on the mounting ring 55. The mounting frame 56 is used to install the bolt placement basket 6.

[0035] The bolt placement basket 6 includes a base 61. A grid plate 62 is fixedly installed on each of the four sides of the upper end of the base 61. Connecting blocks 63 are fixedly installed on the upper ends of the grid plates 62, and the connecting blocks 63 are connected end-to-end. The base 61 and each connecting block 63 are fixed to a connecting frame 64. Connecting holes 65 are provided at the four corners of the connecting frame 64. The connecting frame 64 is connected to the mounting frame 56 via screw assemblies and connecting holes 65. The bolt placement basket 6 and the mounting frame 56 are connected by bolt assemblies, making installation and removal simple and facilitating replacement of the bolt placement basket 6 or maintenance of the equipment.

[0036] Working principle:

[0037] Pour rust-preventive oil into the oil reservoir 1, ensuring the oil level is sufficient to submerge the bolts in the bolt placement basket 6. Place the bolts to be oiled into the bolt placement basket 6, align the connecting frame 64 of the bolt placement basket 6 with the mounting frame 56 on the mounting bracket 4, and secure it with screws through the connecting holes 65, ensuring a firm connection.

[0038] The hydraulic cylinder 32 is operated to lower the mounting frame 4. The guide shafts 34 on both sides of the mounting frame 4 are inserted into the guide sleeves 33 of the support plate 31 to ensure smooth descent. The oil flow of the two hydraulic cylinders 32 is controlled by a throttle valve or synchronous motor of the same specification to make the piston movement speed of the two hydraulic cylinders 32 consistent.

[0039] As the mounting bracket 4 descends, the bolt placement basket 6 is immersed in the rust-preventive oil in the oil tank 1. The immersion continues until the bottom of the bolt placement basket 6 is a certain distance from the bottom of the oil tank 1, ensuring that the rust-preventive oil level is higher than the top of the bolt placement basket 6, so that the bolts are completely submerged.

[0040] The motor 53 is started, which drives the rotating shaft 54 ​​via the reducer 52, causing the bolt placement basket 6 to rotate at a constant speed. As the bolt placement basket 6 rotates, the rust-preventive oil penetrates into the bolt gaps, forming a uniform oil film on the surface. The oiling time is set according to the bolt specifications. After oiling is complete, the piston rod of the hydraulic cylinder 32 extends, causing the mounting bracket 4 to rise, and the bolt placement basket 6 to leave the oil surface. Excess rust-preventive oil begins to drip. The dripping rust-preventive oil flows back to the oil storage tank 1 through the grille of the oil-permeable base 42 and the oil inlet hole of the vertical plate 41.

[0041] When the bolt placement basket 6 rises to a suitable position above the oil tank 1, the hydraulic cylinder 32 stops operating, and the operator observes and confirms that the bolts are dry. Loosen the screw assembly between the connecting frame 64 and the mounting frame 56, remove the bolt placement basket 6 and move it to the unloading station to pour out the oiled bolts.

[0042] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
