Description

Technical Field

[0001] This utility model relates to the technical field of honeycomb aluminum plate stretching equipment, and specifically to a clamping device for a honeycomb aluminum plate stretching machine. Background Technology

[0002] In manufacturing, honeycomb aluminum panels are a widely used material in fields such as construction, aerospace, and automobiles. It consists of two aluminum panels sandwiching a honeycomb structure, which offers high strength, light weight, good thermal insulation, and high tensile and compressive strength.

[0003] In related technologies, such as the aluminum honeycomb core stretching and shaping device disclosed in CN115815448A, the device includes: a support frame and a fixed clamping bracket fixedly installed on one side of the support frame; a sliding clamping bracket is provided on the opposite side of the fixed clamping bracket; a first linear slide rail is installed on the support frame; the first linear slide rail includes a first guide rail fixedly connected to the support frame; a power device capable of driving the sliding clamping bracket to move in the length direction of the first guide rail; multiple piercing mechanisms are provided on both the fixed clamping bracket and the sliding clamping bracket; a set of second linear slide rails is fixedly connected to the fixed clamping bracket; another set of second linear slide rails is fixedly connected to the sliding clamping bracket; and the piercing mechanisms slide on the second linear slide rails.

[0004] The honeycomb core produced by this equipment has a more uniform structure and will not have large local deformation, resulting in a higher quality honeycomb core. It mainly uses a piercing mechanism to pierce and position one end of the honeycomb core. The needle can be used to position the cavity of the honeycomb aluminum plate. However, because the needle is relatively thin and long, some aluminum plates are prone to breakage during stretching. To solve the above problem, a clamping device for a honeycomb aluminum plate stretching machine is proposed. Utility Model Content

[0005] In view of this, the present invention provides a clamping device for a honeycomb aluminum plate stretching machine. The present invention uses a hydraulic cylinder in the positioning component to drive the extension end to rise and fall, thereby controlling the rise and fall of the pressing block connected to the hydraulic cylinder, so that the pressing block enters the groove to press and clamp the honeycomb core. The horizontal and vertical stripes set at the bottom of the pressing block increase the friction between the pressing block and the honeycomb core. The positioning pin in the groove is inserted into the socket of the honeycomb core to prevent the honeycomb core from breaking during the stretching process.

[0006] To solve the above-mentioned technical problems, this utility model provides a clamping device for a honeycomb aluminum plate stretching machine, including a frame of the honeycomb stretching machine, movable devices arranged on both sides of the frame, a fixed frame arranged between the movable devices, and multiple positioning components arranged on the fixed frame. Each positioning component includes a support block arranged on the fixed frame. The support block is in the shape of an upright E. A hydraulic cylinder is arranged at the top of each support block, and a movable opening is arranged at the bottom of the support block. A pressing block is arranged at the end of the hydraulic cylinder that passes through the movable opening. A support plate is arranged on the lower surface of the support block. The support plate is in the shape of an L, and the pressing block corresponds to the bearing surface of the support plate.

[0007] Each pressing block includes an upper pressing block and a lower pressing block. The upper pressing block is used to connect the pressing block to the telescopic end of the hydraulic cylinder. The upper pressing block is square-grooved with the groove facing downwards. The top of the lower pressing block is provided with a protrusion that is sealed and adapted to the groove of the upper pressing block. The lower pressing block is used to clamp the honeycomb core.

[0008] The lower surface of the pressure block is provided with a cross pressure plate. The cross pressure plate is used to install horizontal and vertical stripes. The cross pressure plate has several horizontal stripes in its longitudinal direction. The horizontal stripes are used to facilitate the clamping of the honeycomb core by the cross pressure plate. The vertical stripes are used to reinforce the clamping of the honeycomb core. The cross pressure plate has several vertical stripes in its transverse direction.

[0009] The lower pressure block has a threaded hole at each of the four corners of the cross pressure plate. The threaded hole is used to install bolts, and the lower pressure block is connected to the upper pressure block through the bolts and the threaded hole. The threaded hole passes through the lower pressure block and is embedded in the upper pressure block.

[0010] Each upper pressure block has a limit rod at its four top corners. The limit rod is used to prevent the upper pressure block from touching the support block on the support frame. Each movable opening has a limit groove around its perimeter. The limit groove is used to insert the limit rod. The limit groove is embedded in the bottom of the support block and is compatible with the limit rod.

[0011] The pressing block has a groove in the center of the side corresponding to the support plate. The groove is used to support and position the honeycomb core with the pressing block. Several positioning pins are set in the groove. The positioning pins are convenient to be inserted into the circular recess of the honeycomb core. The positioning pins are truncated cone-shaped.

[0012] The top of the upper pressure block is equipped with a connector, which is used to connect the upper pressure block to the hydraulic cylinder, so that the hydraulic cylinder can be connected to the pressure block, thereby moving the pressure block up and down. The top of the connector is connected to the telescopic end of the hydraulic cylinder.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The hydraulic cylinder in the positioning component drives the extension end to rise and fall, thereby controlling the rise and fall of the pressing block connected to the hydraulic cylinder. This allows the pressing block to enter the groove and press and clamp the honeycomb core. The horizontal and vertical stripes on the bottom of the pressing block increase the friction between the pressing block and the honeycomb core. The positioning pin in the groove is inserted into the socket of the honeycomb core to prevent the honeycomb core from breaking during the stretching process.

[0014] 2. The upper pressure block is used to connect the pressing block to the telescopic end of the hydraulic cylinder, and the lower pressure block is used to clamp the honeycomb core. By inserting the protrusion into the groove at the bottom of the upper pressure block, and then using the threaded hole and bolts, the upper pressure block and the lower pressure block are detachably connected and fixed, which facilitates subsequent maintenance of the equipment components.

[0015] 3. The limiting rod is used to prevent the upper pressure block from touching the support block on the support frame. The limiting groove is used to insert the limiting rod. The groove is used to cooperate with the pressing block to reinforce and position the honeycomb core, thereby preventing the pressing block from being overloaded. Attached Figure Description
