Problems solved by technology

[0004] There are many deficiencies in the traditional knife grabbing mechanism: 1. The structure is complex, the assembly efficiency is low, and maintenance and inspection are inconvenient; A certain amount of space; 3. There are many parts involved, and the modularity is poor. It is troublesome to replace the parts, wasting a lot of time and human resources, and the work efficiency is low.

Embodiment 1

[0024] The integral claw of embodiment 1, as shown in the figure, includes a claw body made of spring steel. A groove 3 is respectively opened on both sides of the claw body, and two grooves 3 are respectively along the length of the claw body. Direction setting, two grooves 3 divide the claw body into a clamping part and a fixed part 1, and the fixed part 1 is provided with four threaded holes for installing flat-end set screws (not shown in the figure) 11. Flat-end set screws are used to fix the integral claw on the mounting frame (not shown in the figure). The clamping part includes two elastic front forks 2, and the two elastic front forks 2 are arranged on the side of the fixing part 1. Both sides, the front side of fixed part 1 is provided with concave notch 12, and the front end of fixed part 1 is arc-shaped, and the front end of fixed part 1 is provided with arc-shaped boss 13, and the front part of fixed part 1 is opened with Block groove 14, block 4 is fixed in the b...

Embodiment 2

[0025]As shown in the figure, embodiment 2 includes a claw body made of spring steel. A groove 3 is respectively provided on both sides of the claw body, and two grooves 3 are arranged along the length direction of the claw body respectively. The width a of the groove 3 is 6.3 mm, and the two grooves 3 divide the claw body into a clamping part and a fixed part 1, and the fixed part 1 is provided with four setscrews for installing flat ends (Fig. (not shown in the figure) threaded hole 11, the flat end set screw is used to fix the integral claw on the mounting bracket (not shown in the figure), the clamping part includes two elastic front forks 2, two elastic front forks 2 are arranged on both sides of the fixed part 1, and the inner surfaces of the two elastic front forks 2 are inclined, and the inner surfaces of each elastic front fork 2 are gradually inclined from the front end of the elastic front fork 2 to the groove 3, and each The inclination angle α of the inner surface...

Abstract

The invention discloses an integrated knife claw. The knife claw comprises a knife claw body, the two sides of the knife claw body are each provided with a groove, the two grooves are formed in the length direction of the knife claw body, the knife claw body is divided into a clamping portion and a fixing portion through the two grooves, the clamping portion and the fixing portion are integrally arranged, the clamping portion comprises two elastic front forks which are arranged on the two sides of the fixing portion correspondingly, an inwards-concave gap is formed in the front side of the fixing portion, the front end of the fixing portion is in a circular arc shape, a circular-arc boss is arranged at the front end of the fixing portion, each groove extends to the rear portion of the fixing portion from the front end of the fixing portion, the front ends of the two elastic front forks are located in front of the front end of the fixing portion, a protrusion portion is fixedly arranged on the inner side of the front end of each elastic front fork, and the boss and the protrusion portions are matched with clamping grooves in a knife handle of a knife. Modular design is adopted in the integrated knife claw, the structure is simple, replacement and adjustment are convenient and efficient, the matching degree of the knife claw and the knife is high, and the knife can be firmly and reliably clamped.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to an integral knife claw. Background technique [0002] With the acceleration of the process of Industry 4.0, there are higher requirements for the efficiency, reliability and modularity of CNC machine tools. The traditional CNC machine tool grabbing mechanism is usually composed of a pair of claws, a mechanical arm and other parts. It uses a hydraulic power source to control the angle and torque of the pair of claws through oil pressure, so that the tool is clamped by hydraulic pressure. state, to achieve the purpose of grasping the knife. [0003] figure 1 It is a schematic structural diagram of a typical traditional knife grabbing mechanism, figure 2 for 2x magnification figure 1 Middle A-A sectional view, image 3 for 2x magnification figure 1 Middle B-B sectional view, Figure 4 for 2x magnification figure 1 Middle C-C section view. The knife grab mech...
