Description

Technical Field

[0001] This utility model belongs to the field of fastener processing technology, specifically a low-temperature tempering and unloading device for fastener quenching. Background Technology

[0002] Fasteners are a wide range of mechanical parts used for fastening connections. They are used to fasten two or more parts (or components) together into a whole. They are mainly used to connect, fix, and position parts, ensuring the reliability, safety, and durability of the connected components, and also to transmit force. They are widely used in various machinery, equipment, vehicles, ships, railways, bridges, buildings, etc. Fastener quenching is an important heat treatment process to improve the performance of fasteners. Low-temperature tempering can reduce brittleness and improve the toughness and stability of materials while maintaining high hardness. During the low-temperature tempering process, tools are needed to handle fasteners.

[0003] Chinese Patent Application No. 202322484795.5 discloses a low-temperature tempering and unloading device for fastener quenching, including a clamp body assembly, a central shaft assembly, a nut support assembly, a corner plate support assembly, and a locking mechanism. This utility model utilizes a clamp body assembly adapted to a screw, with the screw's head serving as a limiting point. The movable nut support assembly uses the nut's unique through-hole structure to interlock with the screw, forming a horizontal lock to prevent the fastener from falling due to insufficient clamping force during unloading. The corner plate support assembly supports the bottom of the corner plate, preventing it from falling due to insufficient clamping force. This solves the problem that existing ordinary clamps are difficult to stably clamp and unload fasteners, and are prone to falling and damage.

[0004] However, the above-mentioned low-temperature tempering and unloading device for fastener quenching has the following problems in actual use: relying on hand gripping force for clamping is prone to loosening, which is not conducive to the unloading of fasteners; secondly, the unloading process is close to a high-temperature environment, which can easily cause burns to the hands.

[0005] Therefore, a low-temperature tempering and unloading device for fastener quenching is proposed to address the above problems. Utility Model Content

[0032] 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.

[0033] like Figures 1 to 5 As shown, this utility model provides a low-temperature tempering material handling device for fastener quenching, including a clamp body assembly 1, a clamp body drive assembly 2 connected to the clamp body assembly 1, a telescopic gripping rod 3 connected to the clamp body drive assembly 2, and a protective cover plate 4 provided on the telescopic gripping rod 3. The protective cover plate 4 can isolate some hot air and further protect the hands.

[0034] The clamp assembly 1 includes two clamps 11 arranged in a cross configuration, and a first rotating shaft 12 is installed at the cross position of the clamps 11.

[0035] The clamp drive assembly 2 includes a second rotating shaft 21 at the tail end of the clamp body 11, a swing arm 22 connected to the second rotating shaft 21, a third rotating shaft 23 connected to the end of the swing arm 22, an electric telescopic rod 24 connected to the third rotating shaft 23, a bracket 25 connected to the electric telescopic rod 24, a first rotating shaft 12 connected to the bracket 25, and a telescopic grip 3 connected to the bracket 25. The electric telescopic rod 24 and the transmission structure drive the two clamp bodies 11 to clamp the fasteners, which can ensure the clamping force and prevent the fasteners from falling off due to insufficient hand strength.

[0036] Specifically, the telescopic grip 3 includes a handle 31, a drive motor 32 is installed inside the handle 31, a threaded rod 33 is connected to the output end of the drive motor 32, the threaded rod 33 passes through the handle 31 and is threaded to a column 34, the column 34 is slidably connected to a positioning slide rod 35, one end of the positioning slide rod 35 is fixedly connected to the handle 31, and the end of the column 34 is fixedly connected to a bracket 25, so that the length of the device is increased to increase the distance between the high temperature environment and the hand, and to avoid burns to the hand.

[0037] Furthermore, the column 34 is provided with a threaded groove 36 and a positioning slide groove 37 respectively. The threaded groove 36 is threadedly connected to the threaded rod 33, and the end of the positioning slide rod 35 is located in the positioning slide groove 37.

[0038] Furthermore, the protective cover 4 is fixed to the grip 31 near the column 34, so that the protective cover 4 is in front of the hand.

[0039] It is worth noting that the clamp body 11 includes a clamp head 111 and a clamp handle 112, and the first rotating shaft 12 is located at the connection between the clamp head 111 and the clamp handle 112.

[0040] It is worth noting that the clamp head 111 is composed of a straight section 1111 and an arc section 1112. The straight section 1111 is provided with an anti-slip protrusion 1113. The straight section 1111 is used to clamp workpieces such as plates, and the arc section 1112 is used to clamp workpieces such as bolts and nuts. The anti-slip protrusion 1113 can increase the friction.

[0041] Among them, the electric telescopic rod 24 and the drive motor 32 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0042] Working principle and process: The operator holds the handle 31 and brings their hand close to the protective cover 4. The handle 31 is equipped with a control button. By pressing the control button, the drive motor 32 of the telescopic handle 3 is activated, which in turn rotates the threaded rod 33. Under the action of the threaded groove 36 and the positioning slide rod 35, the column 34 moves away from the handle 31, thereby increasing the length of the device and increasing the distance between the high-temperature environment and the hand to avoid hand burns. The protective cover 4 can isolate some hot air and further protect the hand. The electric telescopic rod 24 of the clamp body drive assembly 2 is activated, and the electric telescopic rod 24 retracts, which pulls the swing rod 22 to move. Then the clamp body 11 rotates around the first rotating shaft 12, which can clamp the fastener and send the fastener into the tempering position. The electric telescopic rod 24 and the transmission structure drive the two clamp bodies 11 to clamp the fastener, which can ensure the clamping force and prevent the fastener from falling off due to insufficient hand strength.
