Abstract

The utility model discloses a special machine tool for processing a carrier roller steel pipe, which is composed of a pair of special fixtures 1, a power sliding platform 2, a bed body 3 and a standard boring pin power head 4, wherein the centering of each of the special fixtures 1 and clamping position are provided with a pair of circular arc pincers openings 5, and the jaw openings 5 are fixedly arranged on a bearing seat 6. The bearing seat 6 is arranged on a dovetail guide rail 7 and can slide along the dovetail guide rail 7, and the dovetail guide is fixed on the power sliding platform 2. The utility model realizes that centering is automatic when the carrier roller steel pipe is processed, and ensures the coaxiality of bearing seat holes at two ends of the steel pipe. The wall thickness of the processed bearing seat holes is even, and the carrier roller steel pipe is clamped by the jaw opening with a double circuit arc surface. At the time of clamping, deformation is reduced, and the radial runout of a processed carrier roller is small. Rotating resistance is small, and the utility model can increase the quality of the carrier roller and provides an effective guarantee.

Description

Carrying roller steel pipe Special Purpose Machine for Processing
Technical field
The utility model relates to a kind of special purpose machine tool, is a kind of carrying roller steel pipe Special Purpose Machine for Processing specifically.
Background technology
Ribbon conveyer is one of a large amount of equipment that use of transmitting bulk material occasions such as mine, harbour, grain depot.Thousands of carrying rollers are being born heavy carrying and oriented tasks on the conveyer, and its workmanship (as the circular runout in when rotation and resistance etc.) influences the overall performance and the service life of complete machine to a great extent.Carrying roller is made up of carrying roller steel pipe, bearing block, bearing, roller carrier shaft and some sealings, fastening and connector.The pipe of carrying roller steel pipe generally is that the seamless or seamed steel pipe of hot rolling is cut into, and its two ends process the hole of installation shaft bearing.Bearing block can be cast member or stamping parts, is installed in respectively in steel pipe two stomidiums with the mode of interference fit or welding, and a rolling bearing is installed in each bearing block.The outer ring of two bearings is connected with bearing block, and inner ring is connected with roller carrier shaft, adds to form a complete carrying roller behind some necessary bearing seals and the connector.By the final important quality index radial beat eccentricity of carrying roller, rotational resistance and service life etc. inferring that oppositely the crudy of carrying roller steel pipe is one of key factor that influences these final indexs.At present, the following more scabrous problem of the processing ubiquity of carrying roller steel pipe:
1, machining deformation is big
Because the carrying roller steel pipe belongs to crudy and cannot say for sure the thin-walled cylindrical workpiece demonstrate,proved on manufacturing process, reason is that clamping force causes bigger workpiece deformation easily.The size of clamping force on part to be processed, distribution, clamped position and all very big influence is arranged to clamping distortion with the distance of working position etc.The recovery that thin-walled cylindrical workpiece steps up to be out of shape will make has processed the circular hole distortion, causes overproof when serious; Cause the carrying roller warp-wise to beat, rotational resistance increases;
2, the wall unevenness of machining hole is even
Be to save material, carrying roller steel tube blank wall thickness is thinner, and last wall thickness sold thin more after the hole of installation shaft bearing was reprocessed out at two ends, if it is inaccurate to add the centering of steel pipe in man-hour, will cause processing back hole wall inequality, can slacken the intensity of carrying roller when serious greatly.
3, the axiality in steel pipe two end axles bearing hole is not high
" strength of spraining " phenomenon of bearing when disalignment in steel pipe two end axles bearing hole will cause the carrying roller assembling, the useless load and the friction that have increased bearing, thus the rotational resistance of increase carrying roller reduces service life.
Effectively solve above-mentioned three problems, just provide effective guarantee for the quality that improves carrying roller.
The utility model content
Technical problem to be solved in the utility model is to remedy the blank that prior art exists, and a kind of carrying roller steel pipe Special Purpose Machine for Processing that can effectively solve three problems in the above-mentioned carrying roller steel pipe process is provided.
The utility model carrying roller steel pipe Special Purpose Machine for Processing is made up of special fixture, power slide, lathe bed and standard boring pin unit head.The centering of special fixture and the position of clamping are a pair of circular arc jaws, and jaw is fixedly mounted on its supporting base, and supporting base is installed on the dovetail guide on the clamp base, can slide along dovetail guide.Clamp base and power slide are installed on the same bed ways.
The utility model carrying roller steel pipe Special Purpose Machine for Processing has realized that the carrying roller steel pipe adds the self-centering in man-hour, has guaranteed the axiality in steel pipe two end axles bearing hole, and the wall thickness of the bearing saddle bore of processing is even; Clamp the carrying roller steel pipe with two arc surface jaws, step up distortion and reduce, the carrying roller circular runout that processes is little, and rotational resistance is little; For the quality that improves carrying roller provides effective guarantee.
Description of drawings

Fig. 2, be the A-A profile of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: carrying roller steel pipe Special Purpose Machine for Processing is made up of a pair of special fixture 1, power slide 2, lathe bed 3 and standard boring pin unit head 4.The centering of special fixture 1 and the position of clamping are a pair of circular arc jaws 5, and jaw 5 is fixedly mounted on its supporting base 6, and supporting base 6 is installed on the dovetail guide 7, can slide along dovetail guide 7.The clamp base of carrying dovetail guide then straddles on bed ways, can slide along bed ways to be fixed together with pressing plate and bed ways man-hour to adjust the position of clamping steel pipe, to add.
Step with carrying roller steel pipe Special Purpose Machine for Processing processing carrying roller steel pipe is as follows:
1, the preparation of carrying roller steel tube blank
Select steel tube blank and according to the length cutting stock of carrying roller by the diameter that will process carrying roller.
2, the preparation of circular arc jaw
The jaw that leaves allowance is installed in the jaw supporting, and both beat telltale mark or locate with taper pin; Allow jaw be bearing on its guide rail to slide and adjust to the position that jaw clamps steel pipe, separately left and right sides jaw boring is become to be slightly larger than the circular arc of steel pipe theoretical diameter, and texturing and surface hardening are handled on arc surface with two boring unit heads about on the special plane.
3, adjust the distance of left and right sides jaw
Distance according to the length adjustment left and right sides jaw of carrying roller steel pipe.Unclamp the bridge screw of anchor clamps and bed ways, adjust the distance of left and right sides jaw and tighten bridge screw about preliminary.Such adjustment is carried out repeatedly just finding only distance possibly after reality processing.
4, location and the clamping of steel pipe on anchor clamps
To the instruction that the anchor clamps issue is unclamped, jaw synchronous relative motion under the driving of driving mechanism, jaw is opened; Steel pipe is placed in the middle of two jaws instruction that steps up to the anchor clamps issue again, the action that the jaw counter motion is finished the steel pipe self-centering and stepped up.
5, the bore hole of steel pipe both ends of the surface processing
Slide unit sends the feeding instruction to the left and right, starts boring head simultaneously, finishes the bore hole and the chamfering work on one side separately.Left and right sides slide unit retreats into enable position to be stopped, and boring head stops.
