Abstract

The invention discloses a breakage restoring method for a mechanical arm of a machining center and belongs to the mechanical maintenance technology. According to the maintenance technology, operation is easy, and strength is high after restoration. The method comprises the following steps that 1, a T-type connecting key is manufactured; 2, after two parts of the broken mechanical arm are calibrated, a connecting key groove is machined; 3, the T-type connecting key and the two parts of the mechanical arm are assembled together; 4, pin holes are drilled in the mechanical arm in a matched mode, pins are assembled to enable the mechanical arm and the T-type connecting key to be connected to a whole; 5, the T-type connecting key and the broken mechanical arm are welded together; 6, welding slag is cleared away, drilling and tapping are carried out, and maintenance is completed. The method is simple and practical, and the broken mechanical arm can be restored fast. The method is mainly used for maintaining the tool mechanical arm of the machining center.

Description

A kind of machining center machinery ment splits restorative procedure

Technical field

The present invention relates to a kind of restorative procedure of manipulator, more particularly, particularly relate to a kind of machining center machinery ment and split restorative procedure.

Background technology

Tool magazine in machining center equipment, realizes tool changing by manipulator, meets different processing technologys; General robot manipulator structure comprises tool changing arm and tool lock system, grabs cutter, draws sword, turns round, fills cutter, returns the cutter between process implementation main shaft and tool magazine such as original position and automatically exchange by it.

In actual mechanical process, cause rupturing because the reasons such as misoperation cause the cutter on manipulator and main shaft to collide, be usually difficult to repair; Due to the expensive of manipulator and procurement cycle long, have a strong impact on the effective rate of utilization of equipment; Therefore one is needed can to improve manipulator intensity and quick method of effectively repairing manipulator.

Summary of the invention

For the above-mentioned deficiency of prior art, the technical problem to be solved in the present invention be to provide a kind of simple to operate, repair after intensity high, the machining center machinery ment that can meet instructions for use splits restorative procedure.

The technical solution used in the present invention is such: a kind of machining center machinery ment splits restorative procedure, 1) make a T-shaped connecting key; 2) process connect keyway by clamp after manipulator two parts of fracture being calibrated; 3) by step 1) the T-shaped connecting key that processes and step 2) manipulator two parts of handling well are assembled together and clamp; 4) on two parts manipulator of fracture, join lead plug nail, manipulator and T-shaped connecting key are connected into entirety by assembling pin; 5) manipulator of T-shaped connecting key and fracture is welded together; 6) clear up welding slag, namely drilling-tapping completes maintenance.

Above-mentioned a kind of machining center machinery ment splits restorative procedure, step 1) in, described T-shaped connecting key adopts No. 45 steel makings.

Above-mentioned a kind of machining center machinery ment splits restorative procedure, step 2) in, the length of described connection keyway is consistent with T-shaped connecting key length L, connects the degree of depth of keyway slightly larger than T-shaped connecting key height H.

Above-mentioned a kind of machining center machinery ment splits restorative procedure, step 4) in, described pin hole diameter is 6mm, and the bore position of pin hole is at 1/2 place of T-shaped connecting key and manipulator auxiliary section.

Above-mentioned a kind of machining center machinery ment splits restorative procedure, step 5) in, welding rod is keeped in repair in described welding employing 506.

Beneficial effect

Restorative procedure of the present invention, have simple and practical, workable, conventional machining apparatus and technique can process keyway and T-shaped key, and the manipulator of fracture is by perfect welding procedure, rigidity and the intensity of manipulator can also be strengthened, reduce in process and hit the situation generation of cutter to fracture, and the structure that this method provides is simple, can carry out reparation use fast and resume production, can not manufacturing schedule be affected, reduce the cost purchasing new manipulator.

Accompanying drawing explanation

Fig. 1 is the robot manipulator structure schematic diagram after repairing;

Fig. 2 is the structure enlarged diagram of T-shaped connecting key in the present invention;

Fig. 3 is the structure enlarged diagram that key link slot offered by manipulator.

In figure: 1-manipulator, 2-connects keyway, 3-pin, 4-T type connecting key, 5-soldered.

Detailed description of the invention

Below in conjunction with the specific embodiment in accompanying drawing, the present invention is described further.

Consult shown in Fig. 1 ~ Fig. 3, a kind of machining center machinery ment of the present invention splits restorative procedure, specifically comprises the steps:

(1) make a T-shaped connecting key 4, the T-shaped connecting key 4 in the present invention adopts No. 45 steel makings, to ensure the strength and stiffness requirement of connecting portion.

(2) process connect keyway 2 by clamp after manipulator 1 two parts of fracture being calibrated, when processing connection keyway 2, should ensure that the length connecting keyway 2 is consistent with T-shaped connecting key 4 length L, the degree of depth connecting keyway 2 is slightly larger than T-shaped connecting key 4 height H, consistent to ensure coincideing of connection.

(3) manipulator 1 two parts that the T-shaped connecting key 4 step (1) processed and step (2) are handled well are assembled together and clamp;

(4) on two parts manipulator 1 of fracture, join lead plug nail 3, manipulator 1 and T-shaped connecting key 4 are connected into entirety by assembling pin; Described pin hole 3 diameter is 6mm, and the bore position of pin hole 3 is at 1/2 place of T-shaped connecting key 4 with manipulator 1 auxiliary section.

(5) welded together with the manipulator 1 of fracture by T-shaped connecting key 4, and reach the soldered 5 of technological requirement, welding rod is keeped in repair in described welding employing 506.

(6) clear up welding slag, namely drilling-tapping completes maintenance.

Method of the present invention not only strengthens rigidity and the intensity of manipulator, reduce in process and hit the situation generation of cutter to fracture, also can carry out the manipulator reparation of rupturing fast, resume production, reduce because maintenance of equipment is on the impact of manufacturing schedule, the cost purchasing new manipulator can also be reduced.

Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these all can not affect effect of the invention process and practical applicability.
