Description

Technical Field

[0001] This utility model relates to the field of bolt cleaning technology, specifically a bolt vacuum dust removal device. Background Technology

[0002] With the continuous improvement of industrial automation, bolt assembly operations are now widely completed using automated equipment. However, in actual production, newly manufactured bolts often have residual metal shavings, rust-preventive oil, or dust and other contaminants adhering to their surfaces. If these contaminants are not removed before assembly, it may lead to problems such as poor thread fit, insufficient tightening force, or corrosion after long-term use. Currently, the industry generally adopts the following three solutions to achieve this goal:

[0003] Option 1 involves manual material handling, where operators use brushes or air guns to clean each bolt individually. However, this option suffers from low efficiency and inconsistent cleaning results, which negatively impacts subsequent automated assembly processes.

[0004] Option 2 uses a brush head and suction method, as shown in publication number CN117943347A. The brush head removes dirt from the surface of the bolt mounting part, and a suction pipe is set on the side. Some dirt is sucked into the vacuum cleaner, and some is guided to the dirt collector to complete the cleaning. However, this option does not take into account the bolt transfer problem. If the dirt collector is to be transferred, an opening design is required, which may result in the dirt not being completely collected and there is a risk of dirt splashing onto the workpiece.

[0005] Option 3 involves using a high-pressure water gun or ultrasonic cleaning. As shown in publication number CN222470020U, the bolts are fed into an ultrasonic cleaning tank via a conveyor belt for cleaning, and then removed by the same conveyor belt. However, the bolts will inevitably retain moisture after ultrasonic cleaning. If not dried, this will accelerate rusting. Drying, on the other hand, adds an extra step, potentially impacting production line speed. Furthermore, this option may struggle to effectively fit the bolts into confined assembly holes.

[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a bolt vacuum dust removal device. Utility Model Content

[0007] The purpose of this invention is to provide a bolt vacuum dust removal device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A technical solution for a bolt vacuum dust removal device includes a mounting plate with a drive cylinder on it. The cylinder's tail end has a trunnion mounting component connected to the mounting plate via a connecting shaft. The cylinder's output end is connected to a double trunnion, which is clearance-fitted with a connecting hole at the lower end of a swing seat. A stepped hole is provided on the left side of the swing seat. An oil-free bushing engages with the stepped hole through threaded holes on both sides. A limiting shaft is located inside the oil-free bushing, with a connecting block at one exposed end. A threaded hole is provided on the side of the connecting block, through which a threaded pin is screwed to connect the limiting shaft to the connecting block. An opening is provided on the front of the connecting block, through which a needle roller cam guide connects to the connecting block. Sliding seats are provided on both sides of the needle roller cam guide, connected to the mounting plate via knurled high-head screws. A brake bolt is located below the sliding seat, connected to the mounting plate via a bracket. A bolt ejector seat is located below the sliding seat, with three holes from left to right: a dust suction hole, a bolt ejection hole, and a bolt blowing hole. The blow-out hole communicates with the nail outlet. The nail outlet is connected to the bolt guide sleeve via an O-ring embedded in the bolt guide sleeve. The lower end of the bolt guide sleeve has a clamp and a lock nut for securing the nail outlet tube. The dust extraction hole is connected to the vacuum generator via a pipeline. The end of the pipeline connected to the dust extraction hole connects the two via a quick-connect fitting. A filter is installed in the pipeline to filter and collect dirt for subsequent processing. The nail outlet has a bolt guide sleeve, and the nail inlet is similarly designed. The structure is simple, easy to operate and maintain, provides stable nail delivery, and facilitates subsequent operations.

[0010] As a preferred technical solution, the output end of the drive cylinder is connected to a double ear ring, and the tail is provided with a trunnion mounting component. The front and rear of the drive cylinder are respectively connected to the sliding seat and the mounting component via connecting pins to prevent the cylinder from jamming during the extension and retraction of the drive sliding seat.

[0011] As a preferred technical solution, the upper left side of the swing seat is provided with an opening and the far end is provided with a countersunk hole. Oil-free bushings are installed on both sides of the opening, and a bolt is passed through the middle to connect with the mounting plate. The swing seat can be rotated by controlling the extension and retraction of the cylinder.

[0012] As a preferred technical solution, the left side of the nail outlet is provided with a dust suction hole, which is connected to the vacuum generator through a pipeline. The end of the pipeline connected to the dust suction hole is connected to the two through a quick-connect coupling. A filter is provided in the middle of the pipeline to filter and collect dirt for easy subsequent cleaning.

[0013] As a preferred technical solution, the nail outlet seat has a nail outlet hole in the middle, which communicates with the blow nail port. The nail outlet port and the bolt guide sleeve are sealed by an O-ring embedded in the bolt guide sleeve. The lower end of the bolt guide sleeve is provided with a clamp and a locking nut for fixing the nail outlet tube.

[0014] As a preferred technical solution, the bolt guide sleeve is provided with a frustum cone, and an air inlet hole is opened obliquely downward around the circumference of the frustum cone. When air is blown from the blow-off port, compressed air enters the air inlet hole through the blow-off port, thereby pushing the bolt forward.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This utility model is a bolt vacuum dust removal device. The swing seat can be driven by a cylinder to swing left and right, thereby realizing the switching of the lower outlet with the nail outlet and the dust removal port, realizing the sealing of the nail outlet and the blown nail channel, and ensuring that dirt is isolated from flying out during dust removal.

[0017] (2) This utility model is a bolt vacuum dust removal device. The swing seat is provided with a stepped hole on the left side, into which the limiting shaft can be inserted. When the swing seat swings left and right, the limiting shaft can be extended and retracted in the swing seat. When dust removal, the swing seat swings to the left, the outlet below the swing seat connects with the dust removal port, the limiting shaft extends out, and the bolt is limited by the limiting shaft before dust removal. After dust removal, the swing seat moves to the right and the bolt falls to the nail outlet. Attached Figure Description
