Technical Field

The utility model relates to a frock clamp technical field especially relates to an adjustable compressor.

Background

For products such as automobile door cover type outer plate products, aircraft wall panel skins and the like, the products have larger overall dimension and thinner thickness. When riveting such large-sized thin-walled products with a reinforcement, a quick clamp is usually used for clamping and fixing. However, this product fixing method has the following problems:

1. the clamp pressing head is made of hard plastic materials or metal materials, so that a product is easily pressed to deform and scratched.

2. The clamp is manually operated, so that the pressing force is not easy to control, and the condition that the product is over-pressed and deformed or not pressed tightly is easy to cause.

Therefore, it is desirable to design an adjustable impactor to solve the above problems.

Furthermore, an opening used for exposing the sliding rod is formed in the side face of the sleeve, and scales are marked on the side face of the opening.

Furthermore, the connecting piece is a universal adjustable supporting leg, one end of the universal adjustable supporting leg is in threaded connection with a threaded hole of the sliding rod, and the other end of the universal adjustable supporting leg is bonded with the rubber plate.

Furthermore, an annular groove is formed in the step surface of the sliding rod.

Furthermore, a locking nut is screwed on the sleeve.

Furthermore, a steel wire thread insert is arranged in the threaded hole of the support, and the steel wire thread insert is in threaded fit with the external thread of the sleeve.

The utility model has the advantages that: the utility model discloses an adjustable compressor can adjust suitable packing force according to the product demand, avoids appearing the product excessive pressure and warp or the not tight condition of pressure, simple structure, small, and it is also more convenient to use.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 2, the adjustable tensioner comprises a support 1, wherein the support 1 is provided with a through support threaded hole 11 along the horizontal direction; the threaded hole 11 of the support is internally screwed with a hollow sleeve 2, and a sliding rod 3, a spring 4 and a plug 5 which can slide along the axial direction of the sleeve 2 are arranged in the sleeve 2. Wherein, the cross section of the slide bar 3 is T-shaped, and the spring 4 is pressed between the large-diameter end of the slide bar 3 and the plug 5; a limiting bulge 21 used for limiting the sliding rod 3 is convexly arranged in the sleeve 2; the small-diameter end of the slide rod 3 is connected with a connecting piece 6, and the end face of the connecting piece 6 is bonded with a rubber plate 7.

Specifically, in the adjustable tensioner, the support 1 is provided with a plurality of mounting holes 12 for mounting the fixed support 1. A steel wire thread insert is arranged in the support threaded hole 11, and the steel wire thread insert is in threaded fit with the external thread of the sleeve 2.

As shown in fig. 2 and 3, an opening 22 for exposing the slide bar is opened on a side surface of the sleeve 2, and a scale is marked on a side surface of the opening 22. When the slide bar 3 is in contact with the limiting surface of the limiting bulge 21, the large end surface of the slide bar 3 is aligned with the initial scale mark of the scale.

Wherein, the sleeve 2 is screwed with a locking nut 8 for locking the sleeve 2 on the support 1 after adjusting the pressing force of the product.

As shown in fig. 4, in the present embodiment, the slide rod screw hole 31 of the slide rod 3 is provided through. Wherein, the step surface of the slide bar 3 is provided with an annular groove 32 for preventing the slide bar 3 from being adsorbed on the limiting surface of the limiting protrusion 21.

In this embodiment, the connecting member 6 is preferably a universal adjustable leg, one end of the universal adjustable leg is screwed into a threaded hole 31 of the slide bar 3, and the other end is bonded with the rubber plate 7. Wherein, universal adjustable supporting leg is prior art, its structure of no longer detailing. Through setting up universal adjustable stabilizer blade, can realize better contact between rubber slab 7 and the product inclined plane of arbitrary inclination.

When the adjustable compactor of the utility model is used, the slide bar 3 and the universal adjustable support leg are driven to move together to the rubber plate 7 to contact with the product skin surface by rotating the sleeve 2; continuing to rotate the sleeve 2, the sliding rod 3 slides relative to the sleeve 2 along the axial direction of the sleeve 2; and observing the scales at the opening 22 on the sleeve 2, stopping rotating the sleeve 2 after the sliding rod 3 moves to a preset scale value, and locking the locking nut 8, thereby completing the compression and fixation of the product surface. By adopting the adjustable tightener, the proper pressing force can be adjusted according to the product requirements, the condition that the product is over-pressed and deformed or not pressed tightly is avoided, the structure is simple, the size is small, and the use is convenient.
