Description

Integrated positioning device

technical field

The utility model relates to a positioning device, in particular to a comprehensive positioning device which utilizes threads for guiding and positioning.

Background technique

In the existing positioning devices, the traditional cylinder guide is generally used, that is, the smooth cylinder and the round hole are used to achieve accurate guidance with a certain fit clearance, but it is very difficult to achieve accurate positioning for this type of structure. The positioning at any position cannot be easily realized; the support rod in the existing positioning device cannot well ensure that the central axis of the cylindrical part is at the specified position, and if you do not pay attention, the central axis will deviate, and it is not easy to adjust it. ; And because the diameters of the cylindrical parts are different, the optimal spacing requirements for the supporting rods are different, and the existing positioning device cannot easily adjust the distance between the supporting rods.

Utility model content

Aiming at the shortcomings of the above-mentioned prior art, the utility model provides a comprehensive positioning device, which can effectively realize precise guidance and positioning, as well as adjustment and alignment of the central axis of cylindrical parts.

In order to achieve the above object, the technical solution adopted by the utility model is: a comprehensive positioning device, including a single plunger rod hydraulic cylinder, a fixed seat, a guide sleeve, a guide positioning rod, a positioning nut, a connecting block and a supporting rod, the hydraulic cylinder Placed vertically, the plunger rod on the top is connected with the connecting block, the supporting rod is fixedly arranged on the connecting block, the upper two sides of the hydraulic cylinder are provided with fixing seats, there are two guiding and positioning rods, and the outer surface is provided with T-shaped thread, respectively socketed in the fixed seat in the vertical direction and a guide sleeve is set between the guide positioning rod and the fixed seat, the upper end of the guide positioning rod is connected to the connecting block and fixed by a nut, and the part under the fixed seat is threaded. There are two set nuts.

Compared with the prior art, the beneficial effects brought by the utility model are: the guide positioning rod uses the cylindrical outer surface of the T-shaped thread and its thread to guide and locate, ensuring the accuracy of the guide; the two positioning nuts can Realize positioning at any position; the cylindrical support rod can ensure that the central axis of the cylindrical part is parallel to the support rod.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, the comprehensive positioning device includes a single plunger rod hydraulic cylinder 1, a fixed seat 2, a guide sleeve 3, a guide positioning rod 4, a positioning nut 5, a connecting block 6 and a supporting rod 7, and the hydraulic cylinder 1 Placed vertically, the plunger rod on the top is connected to the connecting block 6, the supporting rod 7 is fixedly arranged on the connecting block 6, and the fixing seats 2 are arranged on both sides of the upper part of the hydraulic cylinder 1, and the guide positioning rod 4 has two , its outer surface is provided with T-shaped threads, respectively sleeved in the fixed seat 2 in the vertical direction and a guide sleeve 3 is set between the guide positioning rod 4 and the fixed seat 2, the upper end of the guide positioning rod 4 is connected in the connecting block 6 and Fixing by nuts, two positioning nuts 5 are threadedly connected to the part below the fixing seat 2 .

When working, use other feeding devices or manually put the cylindrical blank on the support rod 7, the hydraulic cylinder 1 starts to work, and pushes the connecting block 6 to send the blank to the working position. When the blank reaches the working position, the pre-adjusted and fixed positioning nut 5 is in contact with the fixed seat 2 to prevent the hydraulic cylinder 1 from continuing to move, so as to achieve accurate positioning of the blank. After the blank is fixed, the hydraulic cylinder 1 works in reverse and retreats from the working position. After the blank processing is completed, the hydraulic cylinder 1 works again to the working position, collects the processed products or blanks and returns them, sends the products or blanks back to the original position, and uses other discharge devices or manually to remove the products or blanks, and ends One time workflow.

The guide positioning rod 4 utilizes the cylindrical outer surface of the T-shaped thread and its thread for guidance and positioning, and controls the cylindrical surface of the top of the T-shaped thread within a standard tolerance range through finishing. The guide sleeve 3 is prepared according to the actual size of the guide rod, and is controlled within a certain gap range to ensure the accuracy of the guide. Positioning at any position is realized by adding two positioning nuts 5 to the T-shaped thread.

The cylindrical support rod 7 fixed on the connection block 6 can ensure that the central axis of the cylindrical part is parallel to the support rod 7 . The distance between the two supporting rods 7 is different, which can realize the positioning of cylindrical parts with different diameters, and each fixed distance can realize the positioning of cylindrical parts within a certain range. To realize the positioning of different cylindrical parts in a wider range, the connecting blocks 6 with different distances between the two supporting rods 7 can be replaced.
