Abstract
A kind of hydraulic support top cover clamp for machining, belong to lathe process field, comprise lathe jaw, multiple lathe jaw is all fixedly connected with lengthening pawl, lengthen pawl and lathe jaw connecting portion along main shaft diameter to length be less than lathe jaw length, lengthen pawl in lathe footstock side along main shaft diameter to length be more than or equal to lathe jaw length, lengthen pawl by forming a depressed part between lathe footstock side and lathe jaw, this utility model can decrease alignment time, save process time, improve the working (machining) efficiency of workpiece.
Description
Technical field
The utility model relates to a kind of clamp for machining, and particularly a kind of hydraulic support top cover clamp for machining, belongs to lathe process field.
Background technology
In order to prevent top, tunnel to subside accident in colliery, need to utilize hydraulic support by top braces, top cover is a kind of parts in hydraulic support, top cover blank is a kind of press forging, blank after forging and stamping, blank belongs to toroidal, an end periphery of blank has forged into irregular peripheral projections, add man-hour, need to clamp irregular peripheral projections other positions to top cover and carry out lathe process, after the clamping of irregular peripheral projections position, workpiece is not or not the centre of main shaft, need to carry out centering to workpiece, and the blank of this structure can only clamp irregular peripheral projections in process, irregular due to peripheral projections, make clamping position contact point less, and general be all utilize four paws jaw to clamp in process, alignment time is quite long, this clamping mode not only locates difficulty, and bring certain difficulty to processing, add and can not use too large centripetal force man-hour, bring process velocity slow, working (machining) efficiency is low, for processing master worker, process according to the clamping mode of current lathe, certain difficulty is brought to completing processing tasks accurately, how can improve working (machining) efficiency is the problem that shop floor worker is considered always.
Summary of the invention
Difficult for location in top cover process, clamping is not easy, add and can not use too large centripetal force man-hour, bring the present situations such as process velocity is slow, working (machining) efficiency is low, the utility model provides a kind of hydraulic support top cover clamp for machining, its objective is in order to convenient, loads and unloads processing work neatly, save the workpiece set time, improve working (machining) efficiency.
The technical solution of the utility model is: a kind of hydraulic support top cover clamp for machining, comprise multiple lathe jaw, multiple lathe jaw is all fixedly connected with lengthening pawl, lengthen pawl and lathe jaw connecting portion along main shaft diameter to length be less than lathe jaw length, lengthen pawl in footstock side along main shaft diameter to length be more than or equal to lathe jaw length, lengthen pawl by forming a depressed part between lathe footstock side and lathe jaw, the lengthening pawl that described multiple lathe jaw is fixedly connected with is equal in lathe rotating shaft length axially, multiple lathe jaw is fixedly connected with and lengthens pawl for being welded to connect, multiple be connected with lengthen pawl clamping section distance the alignment of shafts apart from equal, the clamping section of described lengthening pawl is provided with dentalation.
The good effect that the utility model has is: lengthen pawl by being welded to connect one on lathe jaw, and a depressed part is set between the lathe footstock side lengthening pawl and lathe jaw, the protuberance of top cover end can be avoided, the main body section of clamping top cover, the more firm of workpiece clamp can be made like this, and do not need oversize time centering, workpiece loading and unloading simple and fast, particularly the clamping section of multiple lengthening pawl is processed into axle center equidistant, round piece main part can be clamped simultaneously, decrease alignment time, save process time, improve the working (machining) efficiency of workpiece.

Fig. 3 utilizes the chuck front schematic view of clamp top cover in the utility model.
Detailed description of the invention
In order to understand better and carry out the technical solution of the utility model, provide embodiments more of the present utility model at this, these embodiments, in order to better explain technical scheme described in the utility model, are not formed any form restriction of the present utility model.
Be described with regard to the technical solution of the utility model referring to Fig. 1-Fig. 3, wherein, Fig. 2 and Fig. 3 is the schematic diagram that make use of three-jaw clamping work pieces, in figure 1: lathe jaw, 2: lengthen pawl, 3: connecting portion, 4: depressed part, 5: clamping section, 21: top cover, 22: chuck.
The utility model is a kind of hydraulic support top cover clamp for machining, comprise lathe jaw, multiple lathe jaw 1 is all fixedly connected with and lengthens pawl 2, lengthen pawl 2 and lathe jaw 1 connecting portion along main shaft diameter to length L1 be less than the length of lathe jaw 1, lengthen pawl 2 in footstock side along main shaft diameter to length L2 be more than or equal to lathe jaw length, lengthen between pawl footstock side and lathe jaw and form a depressed part 4, the lengthening pawl 2 that described multiple lathe jaw is fixedly connected with is equal in lathe rotating shaft length axially, multiple lathe jaw 1 is fixedly connected with and lengthens pawl 2 for being welded to connect, multiple being connected with lengthens the clamping section 5 of pawl 2 apart from the alignment of shafts apart from equal, clamping section 5 place lengthening pawl 2 is provided with dentalation.
Processing 100 × 5 × 25 sheet material 3-4 block is needed in processing and making process, sheet material is processed into depressed part 4, then, the sheet material of processed depressed part is welded to lathe claw 1 towards on the face of footstock, then the jaw fixtures after lengthening is installed on lathe lathe chuck 22, in order to make the clamping section 4 of jaw fixtures equal apart from the distance at lathe spindle center, lathe claw 1 clamps a φ 40 pole material, bar does not exceed the end face of lathe claw 1, the clamping section 5 lengthening pawl 2 is processed, the clamping section 5 of multiple pawl is consistent apart from alignment of shafts distance, in order to obtain the high strength of clamping section 4, clamping 5 must be able to be clamped workpiece is firm, in clamping section 5 relative to lengthening in the vertical direction of pawl face, process multiple dentalation, then, quenched in dentalation position, clamping section, the hardness in clamp portion is improved with this, in using, in order to improve process velocity, processing uses three-jaw clamping top cover 21, location can be made like this, centering speed is faster, more convenient.
Pawl is lengthened by being welded to connect one on lathe jaw, and a depressed part is set between the lathe footstock side lengthening pawl and lathe jaw, the protuberance of top cover end can be avoided, the main body section of clamping top cover, the more firm of workpiece clamp can be made like this, and do not need oversize time centering, workpiece loading and unloading simple and fast, particularly the clamping section of multiple lengthening pawl is processed into axle center equidistant, round piece main part can be clamped simultaneously, decrease alignment time, saved process time, improve the working (machining) efficiency of workpiece.
After describing various specific embodiment of the present utility model above in detail, those of ordinary skill in the art should be well understood to, according to the various common practise of this area, can carry out various equivalent variations, equivalent replacement according to thinking of the present utility model or simply revise, these all should belong to the scope of technical solutions of the utility model.
