Description

Technical Field

[0001] This application relates to the field of bolt processing technology, specifically a rust removal device for bolt pre-processing. Background Technology

[0002] Bolt: A cylindrical threaded fastener used with a nut in mechanical parts. It consists of a head and a threaded shank, and is used to fasten two parts with through holes. During the manufacturing process, black oxide rust easily forms on the surface of the bolt. If not cleaned, this rust will affect subsequent processing operations; therefore, rust removal equipment is needed to remove the rust.

[0003] Patent CN221390424U discloses a rust removal device for bolt pre-processing. This device uses a stepper motor to drive multiple grinding rollers, which rotate while simultaneously revolving around the surface of the bolt to be rusted, reducing dead angles and improving the efficiency of bolt rust removal. However, this device can only remove rust from a single bolt at a time, resulting in low rust removal efficiency. Furthermore, the device consumes a significant amount of energy, increasing the energy cost of the rust removal process, making its cost-effectiveness low. Utility Model Content

[0004] (1) Technical problems solved

[0005] To address the shortcomings of existing technologies, this application provides a rust removal device for bolt pre-processing, which solves the problems mentioned in the background section.

[0006] (2) Technical solution

[0007] To achieve the above objectives, this application provides the following technical solution: a rust removal device for bolt pre-processing, comprising an outer casing, a rust removal mechanism for removing rust from the bolt surface, and a collection mechanism for collecting rust debris. The top of the rust removal mechanism is fixedly connected to a fixing mechanism for fixing several bolts. The fixing mechanism includes a rear clamping block and a front clamping block. The rear clamping block is located on the upper left side of the rust removal mechanism, and the front clamping block is located in front of the rear clamping block. The rust removal mechanism is fixedly connected to the right side of the outer casing, and the collection mechanism is located below the outer casing.

[0008] By adopting the above technical solution, several bolts can be clamped and fixed by the rear clamping block and the front clamping block to perform rust removal work at the same time, thereby improving the rust removal efficiency of the rust removal device.

[0009] Preferably, the fixing mechanism further includes a base plate and a clamping groove. The bottom of the base plate is fixedly connected to the top left side of the rust removal mechanism, and the rear side of the top of the base plate is fixedly connected to the bottom of the rear clamping block. The clamping groove is formed on the top of the rear clamping block and the front clamping block.

[0010] By adopting the above technical solution, the base plate can be used to fix the rear clamping block while providing upward support to the front clamping block. Furthermore, the evenly spaced clamping grooves can be used to fix several bolts at equal intervals, avoiding the resistance generated during rust removal work that would cause the bolts to squeeze against each other and affect the rust removal effect.

[0011] Preferably, the fixing mechanism further includes a telescopic groove and an electric push rod. The telescopic groove is located at the center of the front side of the rear clamping block, and the electric push rod is fixedly connected to the rear side of the inner wall of the telescopic groove. One end of the electric push rod is fixedly connected to the center of the rear side of the front clamping block.

[0012] By adopting the above technical solution, the distance between the rear clamping block and the front clamping block can be adjusted by extending and retracting the electric push rod in the telescopic groove, and bolts of different sizes can be fixed, thus expanding the application range of the rust removal device.

[0013] Preferably, the rust removal mechanism includes an inlet / outlet and a motor. The inlet / outlet is located on the lower left side of the outer casing. The motor is fixedly connected to the lower right side of the outer casing. A screw is fixedly connected to the output shaft of the motor. A movable tube is threaded onto the surface of the screw. A blocking plate is fixedly connected to the left side of the movable tube. The top of the movable tube is fixedly connected to the bottom of the base plate. A connecting rod is fixedly connected to the bottom right side of the movable tube. A limiting ring is fixedly connected to the bottom of the connecting rod. A limiting rod is slidably connected to the inner wall of the limiting ring. Both ends of the limiting rod are fixedly connected to the left and right sides of the inner wall of the outer casing.

[0014] By adopting the above technical solution, the bolts that are fixed at the inlet and outlet can be used to move in and out. The rotation of the motor output shaft drives the screw to rotate. Under the premise that the moving tube is fixedly connected to the connecting rod at the top of the limiting ring that is slidably connected to the limiting rod, the rotation of the screw drives the moving tube to move left and right. At the same time, it drives the limiting ring at the bottom of the connecting rod to slide on the surface of the limiting rod, thereby driving the fixed mechanism at the top of the moving tube to move.

[0015] Preferably, the rust removal mechanism further includes a connecting plate and a rust removal brush, wherein the top of the connecting plate is fixedly connected to the top of the inner wall of the outer casing, and the top of the rust removal brush is engaged with the bottom of the connecting plate.

[0016] By adopting the above technical solution, the rust removal brush at the bottom of the connecting plate can be used to remove the rust from the bolt surface when the moving pipe drives the bolt clamped by the fixing mechanism to move left and right.

[0017] Preferably, the collection mechanism includes an air inlet and a movable cavity. The air inlet is located at the center of the top of the outer casing. A dustproof plate is fixedly connected to the upper part of the inner wall of the air inlet, and a fan is fixedly connected to the lower part of the inner wall of the air inlet. The movable cavity is located at the bottom of the air inlet, and air outlets are evenly distributed at the bottom of the movable cavity.

[0018] By adopting the above technical solution, the dustproof plate inside the air inlet can be used to prevent debris from floating out of the outer box, and the fan can be used to transport the external air into the active cavity and then blow it into the outer box through the air outlet to prevent debris from accumulating on the surface of the internal components, so that the debris falls into the collection box.

[0019] Preferably, the collection mechanism further includes a chute and a collection box. The chute is located below the inner wall of the outer casing, the side of the collection box is slidably connected to the chute, and a handle is fixedly connected to the upper left side of the collection box.

[0020] By adopting the above technical solution, the slide can facilitate the placement and retrieval of the collection box, and the handle can facilitate the movement of the collection box.

[0021] Preferably, a fixing mechanism for fixing the position of the collection box is provided above the handle. The fixing mechanism includes a fixing plate and a fixing plate. The right side of the fixing plate is fixedly connected to the lower left side of the outer box. The fixing plate and the top of the handle are both fixedly connected with fixing holes. A fixing rod is slidably connected in the fixing hole. A driving plate is fixedly connected to the bottom of the fixing rod. The fixing plate is fixedly connected to the upper surface of the fixing rod. A spring is fixedly connected to the bottom of the fixing plate. The bottom of the spring is fixedly connected to the top of the handle.

[0022] By adopting the above technical solution, the moving plate can be used to move the retaining rod away from the retaining hole opened in the retaining plate, and at the same time, the spring at the bottom of the fixing plate can be compressed, so that the handle can be moved to take out the collection box. The setting of the retaining mechanism enhances the stability of the collection box in a static state.

[0023] (3) Beneficial effects

[0024] This application provides a rust removal device for bolt pre-machining. It has the following beneficial effects:

[0025] 1. This rust removal device for bolt pre-processing, by setting a fixing mechanism, places the bolts sequentially into the clamping grooves opened in the rear clamping block. The electric push rod in the telescopic groove shortens, driving the front clamping block to move towards the rear clamping block connected to the base plate until the side of the bolt fits into the clamping groove opened in the front clamping block. This increases the number of bolts that can be rusted at one time, improves the rust removal efficiency, reduces the operating cost of the rust removal device in the rust removal process, and improves the cost performance of the rust removal device.

[0026] 2. This rust removal device for bolt pre-processing, through the setting of a collection mechanism, has a fan in the air inlet that drives external air through the dustproof plate and into the active chamber. The air is blown from the air outlet to the components inside the outer casing, blowing the debris into the collection box that is slidably connected to the slide groove on the side of the handle. This prevents some debris from accumulating on the surface of the rust removal mechanism and the clamping mechanism, and avoids the debris accumulated in the outer casing falling to the ground when the debris in the collection box is poured out, which would increase the workload of the workers and reduce the cleaning work of the rust removal device.

[0042] Working principle: In use, the lower drive plate 504 is moved down, and the collection box 407 is inserted into the slide groove 406. The control of the lower movement of the drive plate 504 is released. Under the elastic force of the spring 506 at the bottom of the fixed plate 505, the retaining rod 503 at the top of the drive plate 504 is inserted into the retaining hole 502 at the top of the retaining plate 501. The position of the collection box 407 on one side of the handle 408 is fixed. The bolts are placed sequentially into the clamping grooves 306 of the rear clamping block 302.
