Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, specifically to a bolt surface anti-rust treatment device. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener fitted with a nut. It is a type of fastener consisting of a head and a shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection. In order to ensure the performance of the bolt, the surface of the bolt is generally treated with rust prevention during the bolt processing.

[0003] For example, CN221433668U discloses a bolt surface rust prevention treatment device, including a treatment base. Two auxiliary grooves are opened at the top of the treatment base. An auxiliary rod is fixedly installed inside each of the two auxiliary grooves. A movable block is sleeved at one end of each of the two auxiliary rods. An L-shaped plate is set at the top of each of the two movable blocks. A movable frame is set between the inner walls of the two L-shaped plates. A swing box is set at the top of the movable frame. An immersion tank is placed inside the swing box. By setting up the movable block, movable frame, swing box, turntable, convex strip, and rack, rust-preventive oil is injected into the immersion tank. Bolts are sequentially placed inside and repeatedly immersed in the rust-preventive oil. After starting the servo motor, the movable frame is moved left and right, causing the immersion tank to swing back and forth. The rust-preventive oil injected inside continuously sloshes, increasing the contact area between the rust-preventive oil and the bolts, thus improving the rust prevention effect on the bolt surface.

[0004] Although this technology can shake the rust-preventive oil inside the soaking tank, when the soaking tank moves from the far left to the right, the rust-preventive oil inside the tank is easily splashed out due to the impact of inertia against the inner wall of the tank. This not only requires the staff to spend time cleaning up, but also wastes resources. Furthermore, although the rust-preventive oil can shake inside the soaking tank, a large number of bolts piled up inside the tank remain stationary, especially the bolts at the bottom, which do not have sufficient contact with the rust-preventive oil.

[0007] Preferably, each of the buffer mechanisms includes a buffer plate, a support plate, a connecting block, a mounting ring, a plurality of insert rods, and a plurality of springs. The support plate is fixedly connected to the outer periphery of the rotating shaft via the connecting block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 The present invention provides the following technical solution:

[0021] Example 1: A bolt surface rust prevention treatment device includes a support base 1, a soaking tank 2, a rotating shaft 4, a motor 3, a support cylinder 8, a first worm gear 7, a second worm gear 12, a gear ring 14, and a gear 10. The soaking tank 2 is located at the upper end of the support base 1 and is used to soak the bolts. The rotating shaft 4 is rotatably connected inside the soaking tank 2, and the outer side of the rotating shaft 4 is fixedly connected to a number of vertical rods 5 via several horizontal rods 6. The motor 3 is fixed on the support base 1 and fixedly connected to one end of the worm gear 13, providing driving force to the worm gear 13. The support cylinder 8 is fixed at the upper end of the support base 1 and sleeved around the soaking tank 2. Two arc-shaped sliders 15 are fixedly connected to the inner wall of the support cylinder 8, and the two sliders 15 are slidably connected to the annular groove 16 on the outer side of the soaking tank 2 to support the soaking tank 2. The worm gear 7 is fixedly sleeved on the outside of the rotating shaft 4 and located between the support base 1 and the soaking tank 2; the second worm gear 12 is fixedly sleeved on the outside of the connecting rod 11, the connecting rod 11 is rotatably connected to the upper end of the support base 1, the second worm gear 12 and the first worm gear 7 are connected by a worm 13, and the worm 13 is rotatably connected to the support cylinder 8; the gear ring 14 is fixedly sleeved on the outside of the soaking tank 2; the gear 10 is fixedly sleeved on the outside of the upper end of the connecting rod 11 and meshes with the gear ring 14. The rotating shaft 4 drives several vertical rods 5 and several horizontal rods 6 to rotate inside the soaking tank 2. Then, the soaking tank 2 rotates in the opposite direction to the rotating shaft 4, thereby shaking the rust-preventive oil and bolts inside the soaking tank 2, preventing the rust-preventive oil and bolts from being in a static state, and ensuring that the bolts are in full contact with the rust-preventive oil;

[0022] The rotating shaft 4 and the connecting rod 11 rotate in the same direction. The rotating shaft 4 drives several horizontal bars 6 and several vertical bars 5 to rotate. The connecting rod 11 drives the soaking tank 2 to rotate through the gear 10 and the gear ring 14, so that the rotating shaft 4 and the soaking tank 2 rotate in opposite directions, thereby ensuring the stirring effect on the anti-rust oil and bolts inside the soaking tank 2.

[0023] Several balls 17 are embedded in the inner wall of the annular groove 16. The upper and lower sides of the two sliders 15 are connected to several balls 17 in a rolling manner. The cooperation between the sliders 15 and the balls 17 facilitates the rotation of the soaking tank 2.

[0024] In use, motor 3 drives worm gear 13 to rotate. The worm gear drives shaft 4 and connecting rod 11 to rotate synchronously through meshing first worm wheel 7 and second worm wheel 12. Shaft 4 drives several vertical rods 5 and several horizontal rods 6 to rotate inside soaking tank 2. Connecting rod 11 drives gear 10 to rotate. Through meshing gear 10 and gear ring 14, soaking tank 2 rotates synchronously. Shaft 4 rotates in the opposite direction to soaking tank 2, ensuring the agitation effect on rust-preventive oil and bolts inside soaking tank 2, so that bolts can fully contact rust-preventive oil.

[0025] Example 2, the technical solution of which differs from Example 1 includes: two buffer mechanisms 9 are provided on the outside of the rotating shaft 4. Each buffer mechanism 9 includes a buffer plate 91, a support plate 92, a connecting block 93, a mounting ring 94, several insert rods 95 and several springs 96. The support plate 92 is fixedly connected to the outside of the rotating shaft 4 through the connecting block 93. The bottom end of the buffer plate 91 is movably sleeved on the outside of the fixed plate. The mounting ring 94 is fixedly connected to the inside of the buffer plate 91. Several insert rods 95 are evenly fixed at the bottom end of the mounting ring 94. The bottom ends of the insert rods 95 are movably sleeved with the fixed plate. Several springs 96 are fixedly connected between the mounting ring 94 and the support plate 92 and sleeved on the outside of the insert rods 95. The springs 96 buffer the falling bolts to prevent the bolts from being damaged by strong impact with the bottom wall of the soaking tank 2.

[0026] Preferably, the upper ends of both buffer plates 91 are spherical to ensure that when the bolt falls onto the buffer plate 91, it will automatically slide and fall into the soaking tank 2.

[0027] When using the equipment, when the bolt is poured into the soaking tank 2, it will fall onto the buffer plate 91. The buffer plate 91 will move down when it receives the impact of the bolt and squeeze several springs 96. The restoring force of the several springs 96 will buffer the bolt and prevent the bolt from being damaged by a strong impact with the bottom wall of the soaking tank 2.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
