Description

Tool for multi-station machining of special-shaped pipe joint

Technical Field

The utility model relates to a piston processing frock field especially relates to a frock of multistation processing special-shaped pipe joint.

Background

As shown in fig. 1 to 3, the conventional intake manifold processing technology is as follows: step one, machining a plane A and drilling 3 through holes; and a second step: reaming 3 small planes at the B position; and a third step of: processing C department plane and through-hole chamfer, processing D plane and the screw hole on it, processing above-mentioned A, B, C, D department plane and hole and screw thread on it should be respectively at three frock, need 3 clamping processing completions. The process is complicated alternately, and the accumulated error of many times of clamping increases, hardly guarantees the form and position and the required precision of product, and manpower and equipment cost requires much, and the transportation is stacked many times to the material, also occupies great production place, and production efficiency is lower.

Disclosure of Invention

In order to solve the deficiencies in the prior art, the utility model aims to provide a single clamping machining precision is high, reduce the clamping number of times, avoids transporting the material mistake, and the frock that the multistation processing special pipe joint that the manual equipment cost is low, production efficiency is high.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a tool for processing a special-shaped pipe joint in a multi-station mode comprises an index plate power head, a driven tailstock and a bridging plate, wherein two ends of the bridging plate are fixed to the index plate power head and the driven tailstock respectively, the bridging plate rotates along with the index plate power head, a movable V-shaped block and a fixed V-shaped block which are arranged oppositely are arranged on the bridging plate, the movable V-shaped block is connected to the bridging plate in a sliding mode and driven by a sliding driving mechanism to slide, when the special-shaped pipe joint is clamped, the tail end face of the special-shaped pipe joint is tightly attached to the bridging plate, and the outer circumference of the tail of the special-shaped pipe joint is clamped between the movable V-shaped block and the fixed V; the tool further comprises a pressing mechanism pressed on the upper portion of the special-shaped pipe joint.

Furthermore, the pressing mechanism comprises a pressing oil cylinder and a pressing head driven by the pressing oil cylinder.

Furthermore, the index plate power head is a high-precision hydraulic index plate.

Furthermore, the sliding driving mechanism is a transverse moving oil cylinder.

The utility model adopts the above technical scheme, following beneficial technological effect has:

1. the bridging board with the tool is installed on a rotating structure consisting of the index plate power head and the driven tailstock, and the index plate power head is started, so that a workpiece installed on the tool can be driven to perform 360-degree accurate rotating positioning. The sequential processing of a plurality of procedures of the special-shaped pipe joint can be realized only by once clamping, and the working efficiency is greatly improved.

2. By reducing the clamping times of the workpiece, the accumulation error caused by multiple times of clamping and the error (misloading, missing process and the like) caused by manual clamping can be avoided, and the processing precision and the product percent of pass are greatly improved. In addition, labor cost, equipment cost and floor space cost are saved by reducing machines and operators.

Detailed Description

As shown in fig. 4 and 5, the utility model relates to a multi-station tooling for processing special pipe joints, which comprises an index plate power head 1, a driven tailstock 2 and a bridging plate 3, wherein two ends of the bridging plate 3 are respectively fixed on the index plate power head 1 and the driven tailstock 2, the bridging plate 3 rotates along with the index plate power head 1, a movable V-shaped block 4 and a fixed V-shaped block 5 which are oppositely arranged are arranged on the bridging plate 3, the movable V-shaped block 4 is connected on the bridging plate 3 in a sliding way and driven by a sliding driving mechanism 8 to slide, a V-shaped clamping mechanism on the bridging plate 3 clamps a positioning reference E and a circumference F according to the technical requirements (shown in fig. 1) of the special pipe joint 6, the process is that the end surface of the clamping position at the tail part of the special pipe joint 6 is tightly attached to the bridging plate 3, the special pipe joint 6 is manually clamped to the fixed V-shaped positioning block 5, and the tail part of the rotary special pipe joint, then the V-shaped positioning block 5 is pushed to be pressed on the special-shaped pipe joint 6, so that the special-shaped pipe joint 6 is accurately and stably positioned.

The tool further comprises a pressing mechanism 7 which is used for pressing the upper part of the special pipe joint 6 and is used for pressing the positioned special pipe joint 6 on the bridging plate 3 through a pressing oil cylinder 71 and a pressing head 72 driven by the pressing oil cylinder 71.

The index plate power head 1 is a hydraulic index plate and has the characteristic of high rotary positioning precision.

The sliding driving mechanism 8 is a transverse moving oil cylinder.

The thinking of the utility model is that, because the product adds the blank man-hour, there is not accurate positioning department, consequently adopts V type positioning mechanism to press from both sides tightly, and the principle of automatic alignment fixes a position special-shaped pipe joint 6 to compress tightly through the pressure cylinder, under the cooperation of graduated disk unit head 1 and driven tailstock 2 of high accuracy, can drive special-shaped pipe joint 6 and realize 360 degrees interior accurate rotational positioning, adopt digit control machine tool processing, switching tool. Thus, the machining of the planes A, B, C and D and the holes and threads on the planes A, B, C and D can be sequentially completed (as shown in FIG. 1).

The practice of the present invention has been described with reference to the accompanying drawings, but the invention is not limited to the embodiments described above, which are illustrative rather than limiting, and it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
