Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for embedded parts, and specifically to a processing device for railway embedded parts. Background Technology

[0002] The anti-corrosion coating treatment of the surface of the contact wire embedded parts generally includes surface pretreatment, anti-corrosion paint treatment, and quality inspection. The details are as follows:

[0003] Surface pretreatment includes oiling and rust removal;

[0004] Degreasing: Methods such as organic solvent cleaning or alkaline cleaning are used to remove oil, grease, and dirt from the surface of the embedded parts to enhance the adhesion between the coating and the substrate. For example, organic solvents such as gasoline and trichloroethylene can be used for wiping or soaking to remove oil, while alkaline solutions such as sodium hydroxide and sodium carbonate can be used for spraying or soaking. Rust Removal: Rust removal is usually achieved by sandblasting or shot blasting. High-speed jets of sand or shot impact the surface of the embedded parts to remove rust, scale, and other impurities, achieving a certain surface roughness. The surface roughness after sandblasting or shot blasting is generally controlled between Ra 3.2 and 12.5 μm to provide a good foundation for coating adhesion.

[0005] During the processes of degreasing, sandblasting to remove rust, and spraying anti-corrosion paint on the surface of embedded parts, clamping components are required to hold the embedded parts. However, at the location where the clamping components hold the embedded parts, degreasing, rust removal, and anti-corrosion paint spraying cannot be achieved, which requires secondary processing of the embedded parts and affects processing efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a railway embedded parts processing device to solve the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a railway embedded parts processing device, including a mounting frame, a fixing block detachably mounted on the mounting frame, a sliding groove provided on the fixing block, a bidirectional threaded screw rotatably disposed in the sliding groove, and two sets of clamping components externally threaded to the bidirectional threaded screw, the clamping components being slidably disposed in the sliding groove.

[0008] Furthermore, the clamping assembly includes two symmetrically arranged sliders, with a gripper located below each slider, and a silicone rubber pad fixedly connected to the gripper on the side closest to the embedded part.

[0009] Furthermore, an adjusting block is fixedly connected below the slider, and the adjusting block has multiple equidistant adjusting screw holes, with the gripper threadedly connected inside the adjusting screw holes.

[0010] Furthermore, a butterfly spring washer is provided between the gripper and the adjusting block.

[0011] Furthermore, a partition is fixedly connected to the middle of the chute, and the bidirectional threaded screw is connected to the partition through a bearing.

[0012] Furthermore, the two threads on the bidirectional threaded screw are arranged symmetrically, and the bidirectional threaded screw is driven by a motor, which is mounted on one side of the fixed block.

[0013] The advantages of the railway embedded parts processing device provided by this utility model in the above technical solution are as follows:

[0014] This invention uses two sets of clamping components to clamp the inner and outer sides of the embedded part at different times, so that all positions on the embedded part can be degreased, derusted or sprayed with anti-corrosion paint, avoiding secondary processing, optimizing the processing procedure and improving processing efficiency.

[0015] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure 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 disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] Please see Figures 1-3 A railway pre-embedded part processing device includes a mounting frame 1, a fixing block 2 detachably mounted on the mounting frame 1, a sliding groove 21 is provided on the fixing block 2, a bidirectional threaded screw 3 is rotatably arranged in the sliding groove 21, and two sets of clamping components are externally threaded to the bidirectional threaded screw 3, and the clamping components are slidably arranged in the sliding groove 21.

[0025] Specifically, the two sets of clamping components are divided into an inner wall clamping component and an outer wall clamping component. This utility model uses the two sets of clamping components to clamp the inner and outer sides of the embedded part at different times, so that all positions on the embedded part can be degreased, derusted or sprayed with anti-corrosion paint, avoiding secondary processing, optimizing the processing procedure and improving processing efficiency.

[0026] Furthermore, the clamping assembly includes two symmetrically arranged sliders 4, with a gripper 7 below the sliders 4. A silicone rubber pad 8 is fixedly connected to the gripper 7 near the embedded part. An adjusting block 6 is fixedly connected to the sliders 4. The adjusting block 6 has multiple equidistantly arranged adjusting screw holes 61. The gripper 7 is threaded into the adjusting screw holes 61. A butterfly spring washer 9 is provided between the gripper 7 and the adjusting block 6.

[0027] The gripper 7 has a cylindrical upper section and a rectangular lower section. The silicone rubber pad 8 is fixedly connected to the rectangular section. By changing the adjusting screw hole 61 that is threaded to the gripper 7, the distance between the two sliders 4 in each clamping assembly can be adjusted, thus adapting to various specifications of embedded parts. The position of the slider 4 can be adjusted according to the distance between the middle hole and the outer wall of the embedded part to achieve accurate clamping. By setting the butterfly spring washer 9, the stability of the gripper 7 threaded connection to the adjusting block 6 can be enhanced, and the elastic deformation of the butterfly spring washer 9 can compensate for the rotation angle of the gripper 7, so that the rectangular section on the gripper 7 can face the side wall of the embedded part, ensuring that the silicone rubber pad 8 is positively compressed against the side of the embedded part.

[0028] Furthermore, a partition plate 22 is fixedly connected to the middle of the slide 21, and the bidirectional threaded screw 3 is connected to the partition plate 22 through a bearing. The two threads on the bidirectional threaded screw 3 are arranged symmetrically, and the bidirectional threaded screw 3 is driven by a motor 5. The motor 5 is installed on one side of the fixed block 2 and is a servo motor.

[0029] Specifically, the bidirectional threaded screw 3 is symmetrically arranged with threads at both ends. When the motor 5 drives the bidirectional threaded screw 3 to rotate, the two sliders 4 in the inner wall clamping assembly and the outer wall clamping assembly move away from or close to each other. When the clamping assembly clamps the embedded part from the inside, the two sliders 4 in the inner wall clamping assembly and the outer wall clamping assembly move away from each other, so that the claws 7 on the two sliders 4 in the inner wall clamping assembly abut against the inner wall of the embedded part. Under the action of the silicone rubber pad 8, the claws 7 are prevented from rigidly contacting the embedded part, thus protecting the embedded part. When it is necessary to adjust the clamping position, the mounting bracket 1 drives the fixing block 2 holding the embedded part to the placement location. The motor 5 drives the bidirectional threaded screw 3 to rotate in the reverse direction, and the two sliders 4 in the inner wall clamping assembly and the outer wall clamping assembly move closer to each other. This allows the inner wall clamping assembly to stop clamping the embedded part, and the embedded part to fall to the placement location. Subsequently, the outer wall clamping assembly clamps the embedded part and returns it to the processing station for processing.

[0030] When spraying anti-corrosion paint, the silicone rubber pad 8 has the property of not adhering to the paint, which avoids the paint on the embedded parts from being adhered to the silicone rubber pad 8 and forming defective products. In addition, during the anti-corrosion paint spraying process, equipment to accelerate the solidification of the paint surface can be appropriately added, such as increasing the ventilation area and increasing the working environment temperature.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
