Description

Technical Field

[0001] This utility model relates to the field of sleeve workpiece processing, specifically to a multi-station drilling device for extension rods. Background Technology

[0002] A socket is a common tool used in production, maintenance, and daily life. It's a sleeve that fits over various wrenches and is cylindrical in shape. Sockets are suitable for tightening bolts or nuts in very confined or deeply recessed areas. They can be categorized as cold-extruded sockets, tapered thread sockets, and straight thread sockets. A socket consists of multiple sockets with hexagonal or dodecagonal holes, along with handles, extension rods, and other accessories. An extension rod is an accessory for a socket; one end inserts into the socket, and the other end inserts into the socket wrench. Some extension rods require radial drilling on their polygonal end face sidewalls. Traditional drilling is typically done manually, with each extension rod placed individually onto a drilling machine, which is inefficient. Therefore, a multi-station drilling device for extension rods that can be easily automated is needed. Summary of the Invention

[0003] This utility model addresses the problem that traditional drilling, which typically involves manually placing each hole onto a drilling machine, is inefficient. It proposes a multi-station drilling device for extension rods that can be easily automated, comprising at least two station assemblies.

[0004] A single workstation assembly includes: a feeding rail; a horizontal support is installed on the upper part of the feeding rail, and a vertical drilling machine is installed in the space above the horizontal support;

[0005] The horizontal support has a hollow center, and the following components are sequentially installed on the top surface of the horizontal support: a top column device for the drilling end, a support plate for the drilling end, a support plate in the middle of the rod, and a support device for the extension end.

[0006] The extension rod is secured in the grooves of the borehole end support plate and the rod middle support plate; the borehole end top column device holds one end of the extension rod, and the extension end support device holds the other end of the extension rod.

[0007] Each workstation assembly has 4 workstations, and the number of two or more assemblies allows one group to feed materials to the other group while the other group is being processed, facilitating cyclic feeding.

[0008] During loading, the end to be drilled is aligned with the top post device at the drilling end and placed in the machine. The rod body is placed on the support plate in the middle of the rod to maintain the center of gravity of the rod on the support plate. After placing four rods, the device operates automatically. The extension end support device holds the extension rod in place during processing, and due to the presence of the top post device at the drilling end, the axial position is determined, maintaining stability during drilling. The vertical drilling machine uses an existing drilling machine.

[0009] After the extension rods at all four stations have been processed, the vertical drilling machine resets, and the extension end support device also resets. Then, the support rod of the drilling end top column device pushes the center of gravity of the extension rod to shift, causing the extension rod to fall from the support plate in the rod to the unloading track.

[0010] Preferably, the drill end support plate is provided with a raised recessed hole, into which a drill clamp is inserted; the drill clamp is used to fix the end of the extension rod, which facilitates the drilling process.

[0011] The inner bottom surface of the drilling chuck is provided with a through hole.

[0012] As a preferred embodiment, the borehole end top column device includes: a first horizontal telescopic cylinder, a connecting block, and several support rods;

[0013] All support rods are mounted on the connecting block, which is mounted on the telescopic end of the first horizontal telescopic cylinder. The cylinder body of the first horizontal telescopic cylinder is mounted on the horizontal support.

[0014] The central axis of the support rod is parallel to the telescopic axis of the first horizontal telescopic cylinder;

[0015] The position of the support rod matches the position of the drill chuck, and the central axis of the support rod passes through the midpoint of the groove of the drill chuck.

[0016] Preferably, the extension end support device includes: a second horizontal telescopic cylinder, a movable connecting block, and a movable top head;

[0017] Several through holes are horizontally provided on the movable connecting block. The movable top head passes through the through holes and slides relative to the movable connecting block.

[0018] The movable mandrel includes a mandrel block and a tail rod. The mandrel block is used to hold the end of the extension rod, and the tail rod is used to insert into the through hole. A buffer pad is fitted on the tail rod, and the buffer pad is set between the mandrel block and the movable connecting block.

[0019] The axis of the movable mandrel is parallel to the telescopic axis of the second horizontal telescopic cylinder.

[0020] The telescopic end of the second horizontal telescopic cylinder is connected to the movable connecting block, and the cylinder body is set on the horizontal support.

[0021] Preferably, the feeding track is divided into two sections. The first section is the projection of the horizontal support onto the feeding track, and the remaining part of the feeding track is the second section. The plate surface of the first section is composed of evenly spaced spring clips, with the spacing equal to the width of the spring clips. The spring clips are connected to the second section and integrally formed with the plate surface of the second section. The spring clip-type first section helps to reduce the impact on the feeding track when the extension rod is feeding from the processing plane, thereby extending the service life of the feeding track.

[0022] Preferably, the number of workstation assemblies is two, and they are set up in a mirror image. The mirror image setting is beneficial for the arrangement of the material feeding track.

[0023] The beneficial effects of this utility model are that it can effectively increase the processing efficiency of extension rods and provide a foundation for automated processing. Attached Figure Description
