fig. 3 is a schematic view of a pipe clamping device according to an embodiment of the present invention.
Detailed Description
The invention is described in further detail below by way of specific embodiments:
reference numerals in the drawings of the specification include: the device comprises a workbench 1, a linkage rod 2, a compression rod 3, a buffer spring 4, a left rack 5, a right rack 6, a left gear 7, a right gear 8, a left clamping jaw 9, a right clamping jaw 10, a left clamping block 11, a right clamping block 12, a left clamping wheel 13, a right clamping wheel 14 and a plunger 15.
An embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: the linkage pipe fitting clamping device comprises a workbench connected with the mechanical arm, and the workbench can move along with the movement of the mechanical arm. There is the cavity in the workstation, and the gangbar runs through from top to bottom has the gangbar, and the upper portion welding of gangbar has the apron, and the gangbar is opened there is the inner chamber, has the depression bar in the inner chamber, and the depression bar is in the same place through buffer spring with gangbar inner chamber bottom. The left side of the linkage rod is welded with a left rack, and the right side of the linkage rod is welded with a right rack.
The workbench is provided with a left rotating shaft and a right rotating shaft on two sides of the linkage rod respectively, the left rotating shaft is connected with a left gear through a flat key, the left gear is meshed with a left rack, the right rotating shaft is connected with a right gear through a flat key, and the right gear is meshed with a right rack. When the lower end of the compression bar touches the pipe fitting, the compression bar overcomes the elasticity of the buffer spring and the gravity of the linkage bar to enable the linkage bar to move upwards, and the upper movement of the linkage bar enables the left gear and the right gear to rotate.
The left rotary shaft is connected with a left clamping jaw through a flat key on the back surface of the workbench, and the left clamping jaw is driven to rotate by rotation of a left gear. The right rotating shaft is connected with a right clamping jaw through a flat key, and the left clamping jaw is driven to rotate by rotation of the left gear. The inner side of the lower end of the left clamping jaw is arc-shaped, the inner side of the lower end of the right clamping jaw is arc-shaped, and a notch for accommodating a pipe fitting is formed after the left clamping jaw and the right clamping jaw are combined.
