Abstract

A clamping mechanism for a forging operation machine binding clip is provided. Clamping arms for the binding clip are designed in a left and right diagonal symmetric way; axial force clamping an oil cylinder is converted into clamping force of the clamping arms via a slide block and an inclined block, so binding clip clamping force is constant; and a small binding clip turning radius facilitates manufacturing and maintenance of the binding clip.

Description

Forging manipulator binding clip clamp mechanism

Technical field

The utility model relates to manipulator binding clip clamp mechanism for a kind of forging, especially can make binding clip keep substantially invariable chucking power, and is convenient to processing and maintenance.

Background technology

Forging manipulator is a kind of important subsidiary engine in forging and stamping production process, and the quality of forging and efficiency are had to important impact.And the performance of manipulator binding clip is determining the serviceability of manipulator to a great extent.The clamp mechanism of binding clip is the core of binding clip.

Binding clip clamp mechanism mainly contains following several form at present:

1, long lever formula binding clip, this structural advantages is that clamping force is larger, but part is many, difficulty of processing is large, and appearance and size is that the radius of gyration of binding clip is large.

2, short lever formula binding clip, this structure pull bar tightening force requires large, has strengthened the size of clamping cylinder.

3, sliding block inclined slot type binding clip, this structure is manufactured more convenient, but efficiency is low.

4, thrust clamps binding clip, and the advantage of this structure is that efficiency is high, and maximum shortcoming is that clamping torque changes greatly.When jaw bore is large, chucking power is little, and jaw bore hour chucking power is large, and this chucking power distributes, just in time contrary with instructions for use.

Summary of the invention

In order to overcome the some shortcomings of existing various mechanisms, the utility model provides a kind of novel clamp mechanism: slide block sloping block type binding clip.

The technical scheme that the utility model technical solution problem adopts is: a kind of forging manipulator binding clip clamp mechanism, the slide block skewback of jig arm is housed in binding clip shell, it is characterized in that: two jig arm are diagonal angle symmetric shape each other, driving the part of jig arm action is slide block skewback, slide block skewback is processed with upper left but the skewback opening of opposite direction identical with two of bottom rights angle, match with two skewback openings of slide block skewback in the rear portion of jig arm, thereby guarantee that clamp maintains substantially invariable clamping torque in the course of the work, and jaw there is be greater than the clamping force of clamping cylinder pulling force.

The beneficial effects of the utility model are, no matter jaw clamps where, and clamping force is constant substantially, and jaw are had be greater than the clamping force of clamping cylinder pulling force; The binding clip external diameter radius of gyration is little, manufacture and easy to maintenance.

Below in conjunction with drawings and Examples, the utility model is described further.

Accompanying drawing 1 is the structural front view of the utility model slide block sloping block type clamp.

Fig. 3 is the top view of clamp when holding workpiece B (minimum dimension workpiece).

Fig. 4 is the front view of part (5) jig arm.

Fig. 5 is the top view of part (5) jig arm.

Fig. 6 is the front view of part (7) slide block.Fig. 7 is that the K of part (7) slide block is to view.Fig. 8 is F-F cutaway view of part (7) slide block.Fig. 9 is G-G cutaway view of part (7) slide block.In figure: 1, jaw bearing pin, 2, wedge, 3, workpiece, 4, jaw, 5, jig arm, 6, jig arm bearing pin, 7, sliding fast, 8, binding clip shell, 9, pull bar, the face of cylinder that C, jig arm coordinate with skewback, D, upper left skewback opening, E, bottom right skewback opening

The specific embodiment

In Fig. 1 and Fig. 2, it is upper that jig arm (5) is arranged on binding clip shell (8) by bearing pin (6), and jig arm can be take bearing pin as axle rotation.The face of cylinder (C) and Fig. 7 of left and right two jig arm ends in Fig. 4, Fig. 8, two skewback openings (D) on slide block in Fig. 9 (7) and (E) match.Like this, when slide block (7) is moved to the left under the driving of pull bar (9), jig arm (5) is opened thereupon, as shown in Figure 2; When slide block (7) moves right under the driving of pull bar (9), jig arm (5) is just thereupon closed, as shown in Figure 3.

Claims

1. a forging manipulator binding clip clamp mechanism, the slide block skewback of jig arm is housed in binding clip shell, it is characterized in that: two jig arm are diagonal angle symmetric shape each other, driving the part of jig arm action is slide block skewback, slide block skewback is processed with upper left but the skewback opening of opposite direction identical with two of bottom rights angle, match with two skewback openings of slide block skewback in the rear portion of jig arm, thereby guarantee that clamp maintains substantially invariable clamping torque in the course of the work, and jaw is there is be greater than the clamping force of clamping cylinder pulling force.
