Description

Positioning riveting device

technical field

The utility model relates to a fixing device, in particular to a positioning riveting device.

Background technique

At present, most positioning riveting on the market uses the cylinder to drive the ejector rod to do the feed movement to squeeze the product placed in the groove. During the riveting process, the ejector rod first conflicts with the product and pushes the product to move together until the product and Stop riveting after the side walls of the groove collide, and there are several disadvantages;

One, the movement stroke of the ejector rod is long, the volume is large, and it takes up space; Second, because there is only one positioning point of the ejector rod, the fixing and riveting effect of the product is poor.

Utility model content

In view of the deficiencies in the prior art, the purpose of the utility model is to provide a positioning riveting device, which has the characteristics of higher stability and better riveting effect.

In order to achieve the above object, the utility model provides the following technical solutions:

A positioning riveting device, including a fixed seat, a cylinder that pushes the top block to slide and move on the fixed seat, the fixed seat is provided with a curved connecting rod and a placement groove for placing products, and the placement grooves are opposite to each other There are through holes on the inner side wall, the two through holes are arranged coaxially, the ejector rod inserted into one through hole during its movement is arranged on the top block, and a positioning rod is inserted in the other through hole. The connecting rod is fixedly connected with the pivot pin of the fixed seat, one end of which is hinged with the positioning rod, and the other end is provided with a conflicting end for moving back to the top block after being in conflict with the top block.

The utility model is further configured as follows: the lower end surface of the top block is provided with a slide block, the front end of the slide block in the feeding direction is provided with a wedge-shaped surface, and the conflicting end is set in a spherical shape.

The utility model is further set as: the connecting rod is composed of a first movable rod and a second movable rod, the first movable rod and the second movable rod are integrally arranged and form an included angle less than 180°, the first movable rod The rod is hinged to the positioning rod, and the conflicting end is arranged on the second movable rod and is inclined upward.

By adopting the above-mentioned technical scheme, the cylinder pushes the top block, and the slider set on the lower end of the top block moves on the fixed seat, and the ejector rod set on the top block is slotted into a through hole, and at the same time, the slide block is set at the front end of the feed direction. The wedge-shaped surface is in conflict with the ball-shaped conflicting end, so that the conflicting end moves away from the top block, because the curved connecting rod is composed of the first movable rod and the second movable rod that are integrally arranged, and the connecting rod and the fixed seat are Hinged to form the principle of leverage, the conflicting end is inclined towards the direction of the slider, so that the positioning rod hinged with one end of the connecting rod moves towards the direction of the ejector rod and has a longer stroke, shortening the stroke of the ejector block, the ejector rod is used for riveting, and the positioning rod is used for Hold the product to play a positioning role.

Description of drawings

Fig. 1 is a schematic diagram of an embodiment of the positioning riveting device of the present invention.

In the figure: 1, fixed seat; 11, placement groove; 111, through hole; 2, top block; 21, ejector rod; 22, slider; 221, wedge-shaped surface; 32, the second movable rod; 321, the conflicting end; 4, the positioning rod.

Detailed ways

Referring to Fig. 1, the embodiment of the positioning riveting device of the present invention will be further described.

A positioning riveting device, comprising a fixed seat 1, a cylinder that pushes the top block 2 to slide and move on the fixed seat 1, the fixed seat 1 is provided with a curved connecting rod 3 and a placement groove 11 for placing products, The two opposite inner walls of the placement groove 11 are provided with through holes 111, and the two through holes 111 are arranged coaxially. The top block 2 is provided with a push rod 21 inserted into a through hole 111 during its movement. Another through hole 111 is inserted with a positioning rod 4. The connecting rod 3 is fixedly connected with the fixed seat 1 with a pivot pin. 2 movement of the conflicting end 321, the connecting rod 3 is placed inside the fixed seat 1 to reduce the space it occupies.

The lower end surface of the top block 2 is provided with a slide block 22 which is slidingly connected with the chute provided on the fixed seat, and the front end of the slide block 22 in the feeding direction is provided with a wedge-shaped surface 221, and the conflicting end 321 is set as spherical.

The connecting rod 3 is composed of a first movable rod 31 and a second movable rod 32, the first movable rod 31 and the second movable rod 32 are integrally arranged and form an included angle of 90°, the first movable rod 31 and the second movable rod The positioning rod 4 is hinged, and the conflicting end 321 is arranged on the second movable rod 32 and is inclined upward.

By adopting the above-mentioned technical scheme, the cylinder pushes the top block 2, and the slider 22 provided on the lower end surface of the top block 2 moves on the fixed seat 1, and the ejector rod 21 provided on the top block 2 is slotted into a through hole 111, and at the same time, the slider 22 The front end of its feeding direction is provided with a wedge-shaped surface 221 and is arranged as a spherical conflicting end 321 to conflict, so that the conflicting end 321 moves away from the top block 2, because the curved connecting rod 3 is a first movable rod that is integrally arranged. 31 and the second movable rod 32, the connecting rod 3 and the fixed seat 1 are hinged to form a lever principle, and the conflicting end 321 is inclined towards the direction of the slider 22, so that the positioning rod 4 hinged with one end of the connecting rod 3 moves towards the direction of the ejector rod 21 And the stroke is longer, the stroke of the jack block 2 is shortened, the push rod 21 is used for riveting, and the positioning rod 4 is used to withstand the product and play a positioning role.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
