Description

A kind of bearing location structure

Technical field

The utility model relates to a kind of fork truck industry is welded the location to product location structure that is used for.

Background technology

In the assembly unit welding of fork truck industry to framework shape products such as vehicle frame, balladeur trains, the location is to adopt stationary positioned seat location or shop bolt location basically.After products such as vehicle frame, balladeur train weldings, because the product welding deformation, weldment is difficult to hang and shifts out frock.Or damage tool part; Or whole frock sling; With the mode of knocking product and frock are broken away from.Cause the keeper quick abrasion and have influence on the accurate positioning property of frock product.The locating piece of design adopts 45 steel, improves hardness through Q-tempering, and hardness is generally below 50HRC.Even like this, wearability is still relatively poor in the process that frock is used, and the life-span is short.So easy when having weldering when the weldment structure needs the frock assist location, it is difficult to take out, the frock life-span is short, weld job inefficiency, shortcoming such as labour intensity is big.

Structural member welding tooling, traditional welding part locating surface be machining seldom, and locating surface is more coarse; The stress deformation of postwelding welding work pieces all can increase the friction of workpiece and frock contact surface, causes bigger wearing and tearing to setting element like this; Long-term use can have a strong impact on the service life of setting element; Thereby have influence on the service life of frock, make a big impact to production, product quality is difficult to obtain effectively stable assurance.

Summary of the invention

The purpose of the utility model provides a kind of location structure of long service life.

In order to achieve the above object; The utility model provides a kind of location structure based on bearing, it is characterized in that, is made up of pedestal, cursor and bearing; Cursor is connected with pedestal through long fixed axis; Bearing is connected with cursor through short fixed axis, and a side of pedestal is provided with spacing muscle piece, is located at the cursor below.

The both sides of described bearing are provided with plain washer.

Adopt rolling bearing to replace 45 steel location locating surface when workpiece breaks away from frock, to change rolling friction into by sliding friction; Location workpiece (bearing) locating surface hardness is by bringing up to more than the 60HRC below the original 45HRC; Through changing setting element material, structure, frock improves more than three times service life.The utility model is enhanced productivity greatly, reduces labour intensity, and the frock life-span prolongs, and can continue to keep the Forming Quality of products such as forklift door frame, vehicle frame.

The specific embodiment

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

Embodiment

1) making of pedestal 1: like Fig. 1-4, be the structural representation of the utility model, plate of material is processed two blocks of side plates, a base plate is welded on side plate on the base plate, and the distance A D between two blocks of side plates should process pedestal 1 greater than the width of cursor 3.The bottom surface of pedestal 1 being milled flat, is benchmark with the bottom surface, boring φ AC.

2) making of cursor 3: it is as shown in fig. 1 to mill out profile, at the two ends of cursor 3, middlely bores two holes, the position of the corresponding φ AC in a hole wherein, and the diameter in hole is bigger slightly than φ AC; At the terminal position boring φ of arm AE.The thickness of cursor 3 should be less than the distance A D between two blocks of side plates of pedestal 1, and free to rotate.

3) location of spacing muscle piece: when the center of φ AC and φ AE is on same horizontal plane, spacing muscle piece 7 is being close to fixed-site below the cursor 3 on pedestal 1.

4) making of fixed axis: with Che Weizhu, be close-fitting when making long fixed axis 2 seal in hole φ AC, short fixed axis 6 is a close-fitting when sealing in hole φ AE.

5) apolegamy of bearing 4: bearing 4 can embed the end of cursor 3, and free to rotate on short fixed axis 6.

6) plain washer according to the width of bearing and cursor groove, is selected suitable thick plain washer for the apolegamy part, guarantees that bearing can not free play in the cursor groove.

Operation principle: according to the dimensional requirement of producing product, the utility model is fixed in certain position of work top, under the effect that has no external force, cursor 3 is that φ AC rotates around the hole of pedestal 1 all the time; Let cursor 3 freely change and fall within on the spacing muscle piece 7 of pedestal 1.Because two Kong Yuqi basal planes of cursor 3 are parallel, the height A B of spacing muscle piece 7 joins according to the Kong Yuqi basal plane of cursor 3, so the line in two holes of cursor 3 is horizontal all the time.At this moment, long fixed axis 2 should be in maximum to the distance A G of the side summit Z of bearing 4.The side plane of workpiece is close to bearing 4; At bearing 4 side summit Z horizontal levels, the opposite of workpiece applies power F then, because the center of the hole φ AC of the center of bearing 4 and pedestal 1 is at same horizontal level; Though so under power F effect, cursor 3 can not rotate and twist; And workpiece can arbitrarily not run owing to gravity.As required, after the completion of workpiece weld job, whole soldering member structure can produce stress deformation.With external force F cancellation, this moment, side surface of workpiece also closely contacted stress with bearing 4.Directly with the upwards vertical lifting of seam workpiece.Because cursor 3 upwards has no resistance; When soldering member hung away, with the bearing 4 generation rolling movements on the cursor 3, when resistance can be sling with soldering member, it is more and more littler that AG becomes.Until disengaging, easily weldment is hung out.This moment, cursor 3 fell back to original position again naturally, had saved and had repeated to rotate the trouble that resets.

Claims (2)

1. bearing location structure; It is characterized in that; Be made up of pedestal (1), cursor (3) and bearing (4), cursor (3) is connected with pedestal (1) through long fixed axis (2), and bearing (4) is connected with cursor (3) through short fixed axis (6); One side of pedestal (1) is provided with spacing muscle piece (7), is located at cursor (3) below.

2. a kind of bearing location structure as claimed in claim 1 is characterized in that the both sides of described bearing (4) are provided with plain washer (5).
