Description

Technical Field

[0001] The utility model relates to a fixture used in the production of automobile parts, in particular to a clamping mechanism. Background Art

[0002] The clamping mechanism in the fixtures used in the production of common automotive parts adopts a direct push form, that is, a cylinder is used to directly push the pressure head to clamp the parts. This structure has high requirements on the surrounding area. Taking the horizontal clamping of parts as an example, it is necessary to set the cylinder (with a telescopic rod) and the pressure head in the horizontal direction. This is not applicable to occasions with limited operating space in the horizontal direction. It is difficult to arrange the horizontal cylinder and the pressure head in a limited space. For occasions with ample operating space in the horizontal direction, the structure of the pressure head is controlled by the telescopic rod of the cylinder, especially when the telescopic rod needs to be extended a long distance to clamp, and its clamping stability is not enough.

[0021] The present invention is further described below with reference to the embodiments.

[0022] See also Figure 1-3 The utility model discloses a clamping mechanism, which comprises a cylinder pushing component and a clamping component.

[0023] As shown in the figure: the cylinder push assembly includes a cylinder 1, a connecting rod 2, a positioning sleeve 3, a fixed flange 4, a bushing 5, and a washer 6; wherein: the telescopic rod of the cylinder 1 is connected to one end of the connecting rod 2; the connecting rod 2 is connected to the positioning sleeve 3 by sliding, and the positioning sleeve 3 is also connected to the fixed flange 4 passing through the connecting rod 2; a bushing 5 is slidingly arranged between the fixing flange 4 and the connecting rod 2, and a washer 6 is arranged at the upper and lower ends of the bushing 5. In order to ensure stable operation in the vertical transmission direction, the fixed flange 4 of the cylinder push assembly can usually be fixed on a wall or a vertical board, and then cooperated with the bushing 5, washer 6 and other parts to ensure that the connecting rod 2 moves smoothly in the vertical direction.

[0024] The clamping assembly includes a push plate 7, a fixed rod 8, a slide seat 9, a pressure head 10, an inclined pressure rod 11, a spring 12, and an inclined fixed plate 13; wherein: the other end of the connecting rod 2 is fixedly connected to the push plate 7; the push plate 7 is connected to the slide seat 9 through the fixed rod 8; an inclined pressure rod 11 is arranged inside the slide seat 9, and a spring 12 is arranged between the inclined pressure rod 11 and the slide seat 9 (one end of the spring 12 abuts against the inclined pressure rod 11, and the other end abuts against the slide seat 9), the front end of the inclined pressure rod 11 is connected to the pressure head 10, and the rear end is a first inclined surface; the inclined fixed plate 13 is fixedly arranged and has a second inclined surface corresponding to the first inclined surface. The inclined fixed plate 13 is also usually fixed on a wall or a vertical plate.

[0025] In the present invention, in order to avoid the defect that the direct-push type clamping mechanism is arranged in a line in one direction and occupies the operation space, the axial direction of the connecting rod 2 is perpendicular to the axial direction of the inclined pressure rod 11 .

[0026] As a connection method, the upper end of the telescopic rod of the cylinder 1 is connected to one end of the connecting rod 2 by screw fixing. The other end of the connecting rod 2 is connected and fixed to the push plate 7 by screw fixing. The push plate 7 is connected and fixed to the fixing rod 8 by screw fixing; the fixing rod 8 is connected and fixed to the slide seat 9 by screw fixing.

[0027] The use process of this utility model is:

[0028] The telescopic rod of the cylinder 1 is pushed upward and transmitted to the slide seat 9 through the connecting rod 2, etc. The inclined pressure rod 11 in the slide seat 9 contacts the second inclined surface of the inclined fixing plate 13 through the first inclined surface. Through the sliding of the inclined surfaces of the two parts, the upward force is converted into a lateral force, driving the pressure head 10 to achieve clamping.

[0029] When the clamping state needs to be released, the telescopic rod of the cylinder 1 is retracted, and the inner spring 12 of the slide seat 9 drives the inclined pressure rod 11 to retreat, completing the relaxation step.

That is, any equivalent changes and modifications made according to the content of the patent application scope of the present utility model should be within the technical scope of the present utility model.
