Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bolt cleaning equipment, and in particular to a device for cleaning foreign objects from bolt threads. Background Technology
[0002] Bolts are widely used components in various fields. For example, bolts used in construction to fix concrete formwork may have their threads damaged due to factors such as concrete adhesion or rust. In other words, after the concrete on the surface of the bolt dries or when the rust is severe, the nut that comes with the bolt is not easy to screw into the bolt threads, making the bolt unusable and causing unnecessary losses to the user.
[0003] In existing technologies, to reuse bolts that are rusted or adhered to concrete, the bolt surface is typically brushed with a rust-removing brush to remove foreign matter. This method is not only inconvenient and inefficient for workers, but also ineffective in removing foreign matter from the bolt surface. More importantly, when the rust-removing brush comes into contact with the threaded part of the bolt, it can easily damage the thread (e.g., reduce its outer diameter), adversely affecting its normal use. Therefore, it is essential to provide a device that can automatically clean various hardened foreign matter from bolt threads, providing convenience for workers. Utility Model Content
[0004] To overcome the drawbacks of existing manual bolt cleaning methods, which are limited by technology and have the disadvantages described in the background, this utility model provides a bolt thread foreign object cleaning device that, under the combined action of related structures, can automatically fix the bolt to be cleaned through a simple power switch operation, and can rotate from right to left to clean the foreign objects adhering to the bolt. This brings convenience to the workers, improves work efficiency, and minimizes damage to the bolt threads.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A bolt thread foreign object cleaning device includes a base plate, support frames, a non-powered linear slide, an electric screw slide, a motor reduction mechanism, a fixed platform, and a chuck, and also includes a cleaning device. There are at least two support frames, with their lower ends fixedly mounted on opposite sides of the base plate. The linear slide is fixedly mounted on both sides of the two support frames. The electric linear slide is fixedly mounted on the base plate. There are at least two fixed platforms, with their lower ends fixedly mounted on the movable block of the electric screw slide and one side of the base plate, respectively. A shaft is rotatably mounted on the upper end of the fixed platform on the sliding block of the electric linear slide. One side of the electric drill chuck is fixedly mounted on the side end of the shaft. The motor reduction mechanism is fixedly mounted on the fixed platform of the base plate, and a limit seat is fixedly mounted on the side end of the rotating shaft of the motor reduction mechanism. The cleaning device includes an electric push rod, a sleeve, and a cleaning rod. The upper end of the electric push rod is fixedly mounted on the lower side of the sliding block of the linear slide, and the upper end of the sleeve is fixedly mounted on the lower side of the electric push rod. A fixing bolt is installed on the side end of the sleeve, and the upper end of the cleaning rod is movably fitted inside the sleeve and fixed by two fixing bolts.
[0007] Furthermore, the outer diameter of the upper end of the cleaning rod is smaller than the inner diameter of the sleeve.
[0008] Furthermore, one side of the limiting seat has anti-slip teeth.
[0009] Furthermore, the drill chuck and the limiting seat are aligned laterally in a straight line, and the lower end of the cleaning rod, the drill chuck, and the limiting seat are in a vertical plane.
[0010] Furthermore, there are multiple cleaning rods, each with the same outer diameter at the top and different outer diameters at the bottom.
[0011] Furthermore, the lower end of the cleaning rod is tapered, and the width of the lower end of the cleaning rod is smaller than the spacing between every two threads of the bolt to be cleaned.
[0012] Furthermore, when the movable column of the electric push rod is at the lower stop point, the lower end of the cleaning rod is lower than the lower end of the drill chuck and the limit seat; when the movable column of the electric push rod is at the upper stop point, the lower end of the cleaning rod is higher than the upper end of the drill chuck and the limit seat.
[0013] Compared with existing technologies, the advantages of this invention are as follows: Through the combined action of related structures, the bolt head of the bolt to be cleaned is fixed inside the drill chuck. Then, an electric linear slide drives the bolt close to the limiting seat, effectively fixing the bolt between the chuck and the limiting seat. Subsequently, the operator operates an electric push rod to control the lower end of the cleaning rod to contact the upper right side of the bolt. After the motor reduction mechanism is energized, it drives the bolt to rotate. Under the action of the bolt threads, the cleaning rod moves from one end to the other. During this movement, the lower end of the cleaning rod removes rust or cement residue adhering to the bolt, thus providing convenience for the operator, improving work efficiency, and minimizing damage to the bolt threads. In summary, this invention has good application prospects. Attached Figure Description

[0016] Figure 2 This is the circuit diagram of this utility model. Detailed Implementation
[0017] Figure 1 , 2As shown, a bolt thread foreign object cleaning device includes a base plate 1, a support frame 2, a non-powered linear slide 3, an electric lead screw slide M, a motor reduction mechanism M1, a fixed platform 4, a power module A1, power switches S and S1, S2, and an electric drill chuck 5; it also includes cleaning equipment; there are at least two support frames 2, the lower ends of which are respectively fixedly installed on the middle of the two sides of the base plate 1; the lower ends of the two sides of the linear slide 3 are respectively fixedly installed on the two support frames 2; the lower end of the electric linear slide M is laterally fixedly installed on the middle of the base plate 1; there are two fixed platforms 4, the lower ends of which are respectively fixedly installed on the movable block of the electric lead screw slide M and the middle of the right side of the base plate 1; the upper middle of the fixed platform 4 on the sliding block of the electric linear slide M has a horizontal shaft hole, and a bearing 41 is fixedly installed in the shaft hole. A shaft 42 is fixedly installed horizontally within the ring. The limiting seat of the electric drill chuck 5 is fixedly installed on the right end of the shaft 42. The motor reduction mechanism M1 is fixedly installed horizontally on the fixed platform 4 at the right end of the base plate. A limiting seat 6 is fixedly installed on the left end of the rotating shaft of the motor reduction mechanism M1. The cleaning device includes an electric push rod M2, a sleeve 71, and a cleaning rod 72. The upper end of the cylinder of the electric push rod M2 is vertically distributed and fixedly installed on the lower side of the sliding block of the linear slide table 3. The upper end of the sleeve 71 is fixedly installed on the lower side of the movable column of the electric push rod M2. There are threaded holes at intervals on the middle of the right end of the sleeve 71, and a fixing bolt 73 is screwed into each threaded hole. The upper end of the cleaning rod 72 is movably sleeved in the sleeve 71 and fixed by two fixing bolts 73. The power module A1 and power switches S, S1, and S2 are installed in the electrical control box 8. The electrical control box is installed on the right front end of the base plate.
[0018] Figure 1 , 2As shown, the outer diameter of the upper end of the cleaning rod 72 is slightly smaller than the inner diameter of the sleeve 71. The left outer side of the cleaning rod limit seat 6 has anti-slip teeth (effectively fixing the bolt). The middle part of the drill chuck 5 and the limit seat 6 are laterally aligned, and the lower end of the cleaning rod 72, the middle part of the drill chuck 5, and the middle part of the limit seat 72 are in a vertical plane from top to bottom. There are multiple cleaning rods 72, each with the same upper outer diameter and different lower outer diameters (suitable for cleaning bolts with different thread widths). The lower end of the cleaning rod 72 is tapered, and the width of the lower end of the cleaning rod 72 is slightly smaller than the spacing between every two threads of the bolt 9 to be cleaned. When the movable column of the electric push rod M2 is at the lower stop point, the height of the lower end of the cleaning rod 72 is lower than the height of the middle part of the drill chuck 5 and the lower end of the sleeve 71. When the movable column of the electric push rod M2 is at the upper stop point, the height of the lower end of the cleaning rod 72 is higher than the height of the middle part of the drill chuck 5 and the upper end of the limit seat 6. The power input terminals 1 and 2 of power module A1 are connected to the AC 220V power supply via wires. The power output terminals 3 and 4 of power module A1 are connected to the power input terminals 1 and 2 of the three power switches S, S1, and S2 via wires. The power output terminals 3, 4, 5, and 6 of the three power switches S, S1, and S2 are connected to the positive and negative and negative-positive power input terminals of the electric linear slide M, the motor reduction mechanism M1, and the electric push rod M2 via wires.
[0019] Figure 1 , 2As shown, after the AC 220V power supply enters pins 1 and 2 of the power module A1, the power module A1 outputs a stable DC 24V power supply through pins 3 and 4, which enters the power input terminals of the three power switches S, S1, and S2. In this invention, the bolt 9 to be cleaned has its head fixed inside the drill chuck 5 (a mature technology whose working principle is not described in detail here). Then, the handle of the power switch S is moved to the left, connecting pins 1 and 2 and pins 3 and 4 respectively. The positive and negative power input terminals of the electric linear slide M are energized, and the sliding block of the electric linear slide M drives the bolt 9 to move to the right. The right side of the bolt 9 contacts the left side of the limit seat 6. Then, the operator turns off the power switch S, and the bolt 9 is fixed between the chuck and the limit seat 6. Then, the worker moves the handle of power switch S2 to the left, connecting pins 1 and 2 and pins 3 and 4 of power switch S2 respectively. This energizes the positive and negative power input terminals of electric push rod M2, causing the movable column of electric push rod M2 to move the cleaning rod 72 downwards. After the lower end of cleaning rod 72 contacts the rightmost threaded part of the bolt, power switch S2 is turned off. The worker then moves the handle of power switch S1 to the left or right, connecting pins 1 and 2 and pins 3 and 4 or pins 5 and 6 of power switch S2 respectively. The rotating shaft of motor reduction mechanism M1, via limit plate 6, drives bolt 9 to rotate clockwise (counterclockwise towards the bolt) or counterclockwise (clockwise towards the bolt). Due to the continuous threaded part of bolt 9, cleaning rod 72 moves from right to left (the cleaning rod moves from right to left via the sliding block of the unpowered linear slide). During this movement, cleaning rod 72 removes rust or cement adhering to the bolt threads, thus providing convenience for the worker, improving work efficiency, and minimizing damage to the bolt threads. After the foreign objects on the bolt are cleaned, the worker moves the handle of the power switch S to the right, connecting pins 1 and 2 and pins 5 and 6 of the power switch S. The sliding block of the electric linear slide M moves the chuck to the left end a certain distance, and then the power switch S is turned off. The chuck is then loosened and the cleaned bolt is removed. Finally, the worker manually moves the electric push rod and cleaning rod from right to left to the right end, and moves the handle of the power switch S2 to the right. The electric push rod M2 moves the cleaning rod upward a certain distance, and then the power switch S2 is turned off. Then, the process of cleaning foreign objects from the next bolt can begin. Figure 2 In the diagram, power module A1 is a finished product of AC 220V to DC 24V power module; motor reduction mechanism M1 is a finished product of coaxial motor gear reducer with a power of 300W and a shaft speed of 60 revolutions per minute; electric push rod M2 is a finished product of reciprocating electric telescopic rod with a power of 50W; and electric lead screw slide M is a finished product of electric lead screw slide with a power of 100W.
