Abstract

The utility model discloses a clamp for a bearing cover on an excavator. The clamp comprises a base capable of being tightly clamped by a machining lathe; a positioning pin for positioning the bearing cover is mounted on the base; a supporting block is arranged on the base; a pressing board is mounted on the supporting block; and a slot into which a bolt can be inserted is arranged on the pressing board. Compared with the prior art, the clamp provided by the utility model has the advantages of simple structure, high security and reliability, smart design, rapidness in installation and clamping, reduction of labor intensity of workers, money saving and the like.

Description

A kind of anchor clamps that are used for the excavator upper ball cover

Technical field

The utility model relates to a kind of anchor clamps, particularly a kind of anchor clamps that are used for the excavator upper ball cover.

Background technology

At present, bearing cap is a vital part on the excavator, and this part blank is a forging; Be to improve work efficiency, and make things convenient for the design and the manufacturing of forging die, design of forging die is with two and do one and design mould; But forge the blank of coming out like this, just must be divided into two, for a long time by processing; Former process means is that going up crouches to mill with circular peripheral-mill mills out it, but through such method following shortcoming is arranged: 1. operator's labour intensity is big after milling a flat big face earlier; The workman will bring up to workpiece and carry about 1.5 meters high workbench off, and also will remove with strength with boosting-rod during clamping just is enough to fasten workpiece; 2. efficient is low: everyone every machine can only mill out 20 every day under the situation smoothly; 3. loss is big: used φ 200 * 4 circular peripheral-mills be worth for 780$/, on average whenever mill 120 will consume one, and add the easy rust of blade in man-hour, approximately whenever mill 20 and will remove reconditioning again, delay the duration and do not say, also to produce fringe cost; 4. potential safety hazard is arranged: comminuted often bursting apart when this circular peripheral-mill damages, as easy as rolling off a log scuffing operator when the blade fragment flies out, even threaten other workers on next door, so prior art is still perfect inadequately.

Summary of the invention

The purpose of the utility model is: provide a kind of simple in structure, practical, install clamping fast, reduce working strength of workers, economize on the use of funds, safe and reliable a kind of anchor clamps that are used for the excavator upper ball cover, to overcome the deficiency of prior art.

The utility model is to be constructed as follows: a kind of anchor clamps that are used for the excavator upper ball cover; Comprise the pedestal that the processed lathe of ability clamps; Be equipped with on the pedestal and be used for the alignment pin of location bearing lid; Pedestal is provided with back-up block, and pressing plate is installed on back-up block, but pressing plate is provided with the slot of inserting bolt.

Pedestal is provided with suspension hook.

Alignment pin is 2.

The nut that is used to screw bolt is installed on bolt.

Owing to adopted technique scheme; At first the pedestal clamping is also fixing with the jaw of machining tool; Then bearing cap to be split is installed on the pedestal through alignment pin, pressing plate is pushed down bearing cap and pressed fixingly through bolt, start machining tool then and utilize saw blade to cut part; Compared with prior art, the utility model not only has advantage simple in structure, safe and reliable, and design ingenious, install clamping fast, reduce working strength of workers, advantage such as economize on the use of funds.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.

The enforcement of the utility model: a kind of anchor clamps that are used for the excavator upper ball cover; Comprise the pedestal 1 that the processed lathe of ability clamps; Be equipped with on the pedestal 1 and be used for the alignment pin 2 of location bearing lid; Pedestal 1 is provided with back-up block 3, and pressing plate 4 is installed on back-up block 3, but pressing plate 4 is provided with the slot 6 of inserting bolt 5.

Pedestal 1 is provided with suspension hook 7, and when needs were carried, available crane hooks 7 pairs of pedestals 1 of suspension hook to be carried.

Alignment pin 2 is 2.

The nut 8 that is used to screw bolt 5 is installed on bolt 5.

During the utility model work; The jaw 10 that at first utilizes machining tool is with pedestal 1 clamping and fixing; Then with bearing cap to be cut 9 through alignment pin 2 the location and be installed on the pedestal 1; Pressing plate 4 pushed down bearing block 9 and rotate nut 8 press fixed bearing block 9, start machining tool then, cut part with saw blade through bolt 5.

Adopt band sawing machine to substitute to crouch and mill that cutting produces effects behind this part is:

1. raising work efficiency, from original every day every machine everyone can accomplish many of 20 surges to 100, work efficiency has improved 5 times.

2. reduction working strength of workers: the band saw cutting ratio is more steady, and workpiece does not need too big chucking power, and the workman only needs to be enough to fasten workpiece once being with gently with spanner.The band sawing machine workbench overhead highly only has 1/3 of milling machine (X62) in addition.The workman lives lighter up and down.

3. loss is little: the used saw blade of band sawing machine is merely 260 yuan, and every saw blade approximately can cut 1500～2000 lives, and middle does not produce any added value, and the circular peripheral-mill cost of processing is 44 times of band sawing machine processing cost.In addition, band sawing machine adopts be general water-cooled but, X62 then need use oil cooling, this also will practice thrift many spendings.

4. do not have potential safety hazard: band saw cuts that not only noise is low, and sawtooth wearing and tearing or saw blade fracture can not fly out, and can not constitute any potential safety hazard to the operator.
