Embodiment 1

[0024] Such as figure 1 , figure 2 As shown, the present invention includes installation base 1, power source, shaft A4, nut 5, jaw mounting plate 6, jaw 7, rotary support 9, transmission mechanism, shaft B12 and guide mechanism, wherein shaft A4 and shaft B12 are respectively Installed on the installation base 1 through the rotary support 9, the axis A4 and the rotary support 9 and the shaft B12 and the rotary support 9 are connected in rotation, and the axis A and the axis B are parallel to each other; one end of the axis A4 / axis B12 is connected to the installation The output end of the power source on the installation base 1 is connected, and the other end is connected with the shaft B12 / axis A4 through the transmission mechanism; the power source drives the shaft A4 / axis B12 to rotate, and drives the shaft B12 / axis A4 to rotate synchronously and in the same direction through the transmission mechanism. The power source of this embodiment includes a motor 2 and a reducer...

Embodiment 2

[0028] Such as image 3 , Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the installation base 1 of this embodiment is a square frame structure, and the rotary support 9, the nut 5, the jaw mounting plate 6, and the jaws 7 are respectively installed on the two sides of the frame. and the guiding mechanism are all located in the square frame, and the transmission mechanism and the power source are all located outside the square frame. The guiding mechanism of this embodiment includes a linear bearing 15 and an optical axis 16, the optical axis 16 is installed on the installation base 1, and each jaw mounting plate 6 is connected with a linear bearing 15 (there are four linear bearings 15 in total). The jaw mounting plate 6 is slidably connected with the optical axis 16 through a linear bearing 15 . In this embodiment, one optical axis 16 is provided above the axis A4 and below the axis B12 respectively, and the two optical axes 16 are para...

Abstract

The invention relates to an ammunition clamping device. The shaft A and the shaft B are respectively installed on the installation base through a rotary support. One end of the shaft A / axis B is connected to the output end of the power source installed on the installation base, and the other end is passed through a transmission. The mechanism is connected with the axis B / axis A; the two ends of the axis A and the two ends of the axis B are respectively made with thread segments, the thread segments at both ends of the axis A have the same pitch and opposite direction of rotation, and the thread segments at both ends of the axis B have the same pitch and direction of rotation On the contrary, and the direction of rotation of the threaded segments at the same end of shaft A and shaft B is the same; each threaded segment on shaft A and shaft B is threaded with a nut, and a screw pair is formed between the nut and the threaded segments on shaft A and shaft B, A jaw mounting plate is connected between the nuts threaded on the threaded section at the same end of the shaft A and the shaft B, and jaws are installed on the opposite sides of the two jaw mounting plates. The invention has compact structure, reasonable layout, automatic clamping, large clamping force, self-locking, synchronous movement of two clamping jaws, high neutrality, adjustable clamping range and wide adaptability.

Description

technical field [0001] The invention belongs to the field of missile assembly, in particular to an ammunition clamping device. Background technique [0002] During the assembly process of artillery shells and small-caliber missiles, cylindrical components such as seeker, warhead, control cabin, and engine often encounter processes such as bonding, tightening, and spot riveting. A clamping device is needed to clamp the cylindrical components . The power of existing clamping devices is generally divided into pneumatic, hydraulic or electric methods. The clamping force of the pneumatic method is small, and a large hydraulic system is required for the hydraulic method; The claws are rigid and easy to slip. With the continuous improvement of domestic automation transformation requirements in the production and assembly of shells and small-caliber missiles, there is an urgent need for a general-purpose cylindrical clamping device with a large clamping force. Contents of the in...
