Abstract
The utility model discloses a drilling machine gearbox shell in a punching structure. The main body comprises a gearbox shell for mounting a retarding mechanism and a main shaft sleeve for mounting a main shaft. The main shaft sleeve is inserted in the gearbox shell formed through sheet-metal processing and welded on the gearbox shell together, the top of the main shaft sleeve is provided with a connecting plate, a tightening sleeve is arranged at the joint of the gearbox shell and the main shaft sleeve, the circular tightening sleeve is provided with an inner turned-over edge, the main shaft sleeve is matched and welded on the inner circumference of the inner turned-over edge, and the lower edge of the tightening sleeve is welded on the top surface of the gearbox shell which is internally and fixedly provided with a positioning ring. The utility model can fully utilize the advantage of high strength of steel plates, reduce the external size of a reducer shell and the weight of a drilling machine, prolong the service life of the drilling machine than an aluminum casting structure by 50% and reduce the weight than an original aluminum casting structure by 30%.
Description
Technical field
The utility model relates to the speed reducer housing that rig is used, and specifically is meant a kind of speed reducer housing that adopts the mining rigs against outburst of hand-held of punching structure.
Background technique
The main body of the structure of hand-held rigs against outburst ZQS-65/2.5, ZQS-80/3.0 is to constitute by connecting a retarder on the pneumatic motor, pneumatic motor and retarder directly link into an integrated entity, their outside is provided with the housing that a cast inblock forms, and the moving element of motor and retarder parcel is supported on enclosure interior.Present housings such as hand-held rigs against outburst ZQS-65/2.5, ZQS-80/3.0 adopt aluminium matter or cast iron quality mostly.Its advantage is that manufacturing process adopts the casting once-through, so material, processing cost are lower; But in order to realize the requirement of cast shaping process, it is bigger that the wall thickness of housing and external shape need design; In order to satisfy the intensity usage requirement of housing, the wall thickness of housing can not be too little simultaneously.The result who increases wall thickness causes the housing assembly overall weight to increase.The increase of case weight directly causes the increase of rig complete machine weight, and the complete machine weight of homemade hand-held rigs against outburst is at 12～15kg at present, and the weight of its speed reducer shell is at 1.2～1.5kg.The housing of import equipment is owing to adopt non-metallic material, and complete machine weight is about 9kg, and speed reducer shell weight is about 0.7kg, but the intensity of its housing is subjected to very big influence.Rigs against outburst is hand-held operation, and for the rig of equivalent technology performance, in light weight meaning can be reduced operator's labor intensity greatly, have very extensive market prospects, so people always attempts to reduce the weight of hand-held rigs against outburst.
The model utility content
The utility model technical issues that need to address provide the rig housing that a kind of overall volume is little, in light weight, intensity is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of rig speed reducer housing of punching structure, its main body comprise can be connected with motor case be used to install the speed reducer shell of reducing gear and the collar bush that is used to install main shaft of fixedlying connected with the speed reducer shell; Integrally welded after the collar bush of machining moulding and speed reducer shell assembling by the sheetmetal working moulding.
Further improvement of the utility model is: described collar bush is that collar bush is inserted in the hole of reserving at speed reducer shell top with being connected of speed reducer shell, welds together then; The joint of speed reducer shell and collar bush is provided with steps up cover; Describedly step up to overlap circular for the band in-flanges, the inner circumference of its in-flanges cooperates with collar bush and welds, and the end face of lower edge that steps up to overlap and speed reducer shell welds.
Further improvement of the utility model is: speed reducer shell internal fixation is provided with positioning ring; The top of collar bush is provided with connecting plate.
Further concrete structure of the present utility model is: described speed reducer shell lower end is provided with the stretch flanging that cooperates with motor case, and flange is provided with the bolt hole that is connected with motor case.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
Collar bush of the present utility model is through the machining moulding, and the speed reducer housing adopts the thin-sheet metal impact briquetting, adopts welding manner to be assembled into whole speed reducer housing again.Adopt structure of the present utility model can make full use of the high advantage of steel strength, reduce the external volume and the rig weight of reducer shell; Solved that aluminium mass shell body profile volume is big, weight is heavier, intensity is lower, influenced the problem in working life.Take this structure, improve 50% than the aluminum casting structure working life of product, and the more former cast aluminium structure of weight alleviates 30%, and cost of production is basic identical with primary aluminum matter cost.
The main shaft of rig is the parts of boring work, and it bears very big power in the course of the work, and the joint of speed reducer shell and collar bush is provided with steps up cover, has strengthened the support to collar bush, makes main shaft more multistable solid when work, the difficult vibration.Positioning ring can make gear box casing link to each other with motor casing accurately.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, collar bush, 2, step up cover, 3, the speed reducer shell, 11, connecting plate, 12, positioning ring.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further details:
As shown in Figure 1, speed reducer housing main body of the present utility model is made of speed reducer shell 3, the collar bush 1 that is used for the rigging up main shaft.Collar bush 1 is through the machining moulding, and speed reducer shell 3 is molded through panel beating.Collar bush 1 inserts in the hole of reserving on the speed reducer shell 3 and by welding manner is fixedly connected and is integral.Be provided with one in the joint of speed reducer shell 3 and collar bush 1 and step up to overlap 2, to increase the join strength of speed reducer shell 3 and collar bush 1.
Step up to overlap 2 circular for the band in-flanges, the inner circumference of its in-flanges cooperates with collar bush 1 and welds, and steps up to overlap 2 lower edge and contacts and weld with the end face of speed reducer shell 3.
Speed reducer shell 3 inside are provided with positioning ring 12, and positioning ring 12 is after being processed into structural member, is welded on the speed reducer shell 3.Welded top at collar bush 1 has connecting plate 11.
Speed reducer shell 3 lower ends are provided with the stretch flanging that cooperates with motor case, and flange is provided with the bolt hole that is connected with motor case.
Above-mentioned step up to overlap 2, speed reducer shell 3 is steel-sheet metal plate punching spare, can perhaps use press tool that sheetmetal is struck out component according to definite shape, size the whole impact briquetting of above-mentioned parts, then several groups of component are welded together.Gauge of sheet 2-3mm when adopting stainless steel.Can certainly change the thickness of steel plate according to the different strength demand of equipment.
