Abstract

The utility model discloses an A-shaped fixture for welding operation of excavator grabs, which comprises two fixture bodies. The A-shaped fixture is characterized in that the fixture bodies are 'n'-shaped structures, a connecting shaft which is used for being connected with a positioner is disposed on the outer surface of a side wall of each fixture body, a clamp hook which is used for clamping a side beam of an excavator grab is disposed at the end of the inner surface of the side wall of each fixture body, a fastening bolt which is used for transversally fastening the side beam of the excavator grab is arranged on the surface of another side wall of each fixture body, and a fastening bolt which is used for longitudinally fastening the side beam of the excavator grab is arranged on the top of each fixture body. The two fixture bodies are connected to form an 'A'-shaped structure by connecting plates, and the connecting shafts are arranged on the connecting plates on the side walls of the fixture bodies. Suspension lugs are further disposed on the fixture bodies. By the aid of the A-shaped fixture, excavator grabs in different specifications can be quickly connected with the positioners, universality of a tooling is improved, mutual interference between a workpiece (weld joint) and the tooling is avoided during welding operation, secondary clamping is omitted, and the A-shaped fixture further has the advantages of convenience and speediness in installation, safety and reliability.

Description

The A type anchor clamps that the bucket weld job is used

Technical field

The utility model relates to the frock clamp that a kind of weld job is used, and specifically is the frock clamp that a kind of bucket weld job is used.

Background technology

Traditional bucket clamp member is lack of standardization, and it is many to regulate bolt, and clamping is loaded down with trivial details; Waste time and energy, usually clamping is all wanted more than half clock, and security is not high; Block workpiece and damage workpiece during weld job easily, cause and want the secondary clamping, brought very big inconvenience to the operator; And increase operator's labour intensity, more and more do not catch up with the demand of reality.

Summary of the invention

The purpose of the utility model be to provide a kind of have highly versatile, easily and fast, the A type anchor clamps that the bucket weld job of bucket clamping on positioner used of characteristics such as safety.

For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:

The A type anchor clamps that the bucket weld job is used; Comprise clamp; Said clamp is " n " font structure; The outer surface of one sidewall of clamp is provided with the connecting axle that is connected in order to positioner, and the end of its inner surface is provided with the trip in order to the curb girder that blocks bucket, and the surface of another sidewall is provided with in order to the horizontal fastening fastening bolt of the curb girder of bucket; The top of clamp is provided with in order to the vertical fastening fastening bolt of the curb girder of bucket.

Said clamp is provided with two, and two clamps form an angle and connect into " A " font structure through connecting plate, and said connecting axle is located on the connecting plate of clamp sidewall.

Said clamp is provided with hanger, and hanger is fixedly connected with two clamps, and is located at the top of clamp.

Said hanger is located at a side identical with connecting axle on the clamp.

The inside surface of side wall of said clamp is the face with certain angle of inclination, in order to suitable with the curb girder of bucket.

The beneficial effect of the utility model:

(1) utilizes the utility model to make between different size bucket and the positioner and be connected fast, improved the versatility of frock;

(2) when weld job, have mutually noninterfere between workpiece (weld seam) and the frock, do not need the secondary clamping;

(3) horizontal and vertical respectively as long as bolts are regulated in three of lockings, operated with the interior clamping of just can accomplishing in ten minutes, improved operating efficiency greatly;

(4) through surpassing the clamping welding practice of ten thousand bucket products 3 years, not occurring accident one time more, fully prove its safety and reliability.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:

Fig. 1 is the utility model structural representation;

Fig. 2 is a three-dimensional structure diagram shown in Figure 1;

Fig. 3 is that the frock clamp of Fig. 1 is connected the Product Status sketch map with bucket;

Fig. 4 is the cut-away view along A-A line shown in Figure 3;

The structural representation of Fig. 5 for linking together bucket and positioner through the utility model.

Among the figure: 1, clamp; 2, connecting axle; 3, fastening bolt; 4, hanger; 5, connecting plate; 6, bucket; 7, curb girder; 8, side plate; 9, positioner; 10, frock clamp; 11, trip.

The specific embodiment

Like Fig. 1,2,3,4, shown in 5, the A type anchor clamps that a kind of bucket weld job is used comprise clamp 1; It forms certain angle by two identical " n " word clamps and connects into " A " shape through connecting plate 5, and according to the thickness difference of bucket 6 series products common feature curb girders 7 with side plate 8, is provided with a trip 11 at each clamp 1 inboard end; To block the step of curb girder 7 and side plate 8 joint thickness differences, be provided with a fastening bolt 3 at clamp 1 top, its role is to vertically clamp curb girder 7 with trip 11; Be provided with two fastening bolts 3 in clamp 1 side; Its role is to a curb girder 7 and laterally lock, be provided with connecting axle 2 in clamp 1 outside, can with positioner 9 between be connected fast; Be provided with hanger 4 on clamp top, greatly facilitate lifting.

The inside surface of side wall of said clamp 1 is the face with certain angle of inclination, in order to suitable with the curb girder 7 of bucket, make it be connected on the curb girder after, this surface contacts with the surface of curb girder fully, to guarantee the fastness of clamping.

The use installation process of the utility model: when specifically using, through curb girder 7 middle parts that hanger 4 hangs bucket to A type frock clamp 10, " n " shape of clamp is put on the curb girder 7 along opening; The fastening bolt 3 of locking clamp 1 upper end then blocks curb girder 7 docks thickness difference with side plate 8 step place until clamp 1 hook-shaped, makes curb girder 7 all very close to each other up and down, then locks the fastening bolt 3 of clamp 1 side; After all installing A type frock clamp 10 Deng two curb girders 7, the hanger 4 through two ends winches to bucket 6 on the positioner 9, is connected with positioner 9 through connecting axle 2; After the installation; Just can carry out weld job to bucket, after welding a period of time, need be to the bucket changing location; Behind 9 pairs of bucket changing locations of positioner, can proceed the operations of welding sequence to bucket.

The above is the preferred implementation of the utility model; Certainly can not limit the interest field of the utility model with this; Should be understood that; For those skilled in the art, can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the essence and the scope of the utility model technical scheme.
