Description
Technical field
The utility model belongs to Workpiece clamping device, is particularly related to a kind of brill bent axle major axis centre hole clamp.
Background technology
Bent axle just finished product generally comprises the main body consisting of columned major axis and minor axis and the gear edge that is positioned at main body side, and gear is along between major axis and minor axis.In the engineering of Crankshaft Machining, need in bent axle main body, get out several holes and oil groove.The processing mode of perforate is generally: first one end of bent axle is fixed on fixture, then the other end of bent axle is holed and the offering of oil groove.
Traditional bent axle fixture cannot be according to the clamping position of the adjusted size of bent axle, and a sleeve clamp can only be applicable to the bent axle of a specification, and versatility is poor.Therefore, be necessary to research and develop a kind of fixture that bores bent axle major axis centre bore, can, according to the specification of bent axle, adjust the clamping position of bent axle.
Utility model content
The purpose of this utility model is to overcome the above-mentioned defect of mentioning and deficiency, and a kind of brill bent axle major axis centre hole clamp is provided.
The technical scheme that the utility model is realized its object employing is as follows.
A brill bent axle major axis centre hole clamp, comprises the connecting rod that is provided in cylinder output; Two ends, described connecting rod left and right are all fixed with upper holder block; Described upper holder block below is provided with lower lock block; Described lower lock block comprises V-block and the projection being wholely set; Described V-block upper surface offers V-type groove; Described projection is arranged on V-block below; Described V-block is threadedly connected to base plate; On described base plate, offer the groove adapting with projection; Between described V-block and base plate, be folded with cushion block; Described lower lock block rear arranges block; Described block is threadedly connected to base plate; Described block is positioned at a side of V-type groove on V-block; On described block upper surface, near lower lock block place, be provided with L-type groove.
On described base plate, be fixedly installed a pair of cylinder supports frame; Air cylinder board has been threaded on described a pair of cylinder supports frame.
The bottom land of the V-type groove on described V-block offers the logical groove of cutting.
Described cushion block is U-shaped.
This fixture versatility is good, and product is remodeled simple and convenient, and the cushion block that only need to change differing heights just can be applicable to this fixture the bent axle of different size.And change the fixed form of traditional hand-operated clamping into pneumatic pinch, make product quality more reliable and more stable, also greatly promoted operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of V-block;
Fig. 3 is the structural representation of cushion block;
Fig. 4 is the structural representation of block;
Fig. 5 is working state schematic representation of the present utility model;
In figure: 100-cylinder supports frame, 200-air cylinder board, 300-connecting rod, 400-upper holder block, 500-lower lock block, 510-V type piece, 511-V type groove, logical groove, 520-projection, 600-cushion block, 700-base plate, 800-block, the 810-L type groove cut of 512-.
the specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A brill bent axle major axis centre hole clamp, comprises the connecting rod 300 that is provided in cylinder output; Described connecting rod 300 two ends, left and right are all fixed with upper holder block 400; Described upper holder block 400 belows are provided with lower lock block 500; Described lower lock block 500 comprises V-block 510 and the projection 520 being wholely set; Described V-block 510 upper surfaces offer V-type groove 511; Described projection 520 is arranged on V-block 510 belows; Described V-block 510 is threadedly connected to base plate 700; On described base plate 700, offer the groove adapting with projection 520; Between described V-block 510 and base plate 700, be folded with cushion block 600.
During work, projection 520 is inserted in the groove on base plate 700, adjusts the height of V-block 510 by changing the cushion block 600 of different-thickness, then lower lock block 500 is fixed on to base plate 700.Bent axle major axis is positioned over to the V-type groove 511 on V-block 510, starts cylinder, drive connecting rod 300 descending, thereby thereby drive upper holder block 400 to compress and fixed crankshaft major axis near lower lock block 500, facilitate follow-up brill bent axle major axis centre bore.
The left and right sides of connecting rod 300 is all provided with steps up fixture, and therefore, an operator once can operate the clamping of two bent axles, has also improved operating efficiency.
Described lower lock block 500 rears arrange block 800; Described block 800 is threadedly connected to base plate 700; Described block 800 is positioned at a side of V-type groove 511 on V-block 510; On described block 800 upper surfaces, near lower lock block 500 places, be provided with L-type groove 810.
Described block 800 is in order to place the gear edge of bent axle.Generally, the clamping force that cylinder provides can not rotated bent axle in the process of processing.The setting of block 800, plays the effect of location crankshaft angles on the one hand, on the other hand, is also further to have guaranteed that bent axle can not rotate in the process of processing.
On described base plate 700, be fixedly installed a pair of cylinder supports frame 100; Air cylinder board 200 has been threaded on described a pair of cylinder supports frame 100.On air cylinder board 200, place cylinder.
The bottom land of the V-type groove 511 on described V-block 510 offers the logical groove 512 of cutting.In reinforcing the process of bent axle, on bent axle, can fall unavoidably and write broken cutting, the broken accumulation bent axle that can wear and tear of cutting.Logical setting of cutting groove 512, in order to broken the cutting of convenient discharge.
Described cushion block 600 is U-shaped.Therefore, the left and right sides of projection 520 is cushion block 600.Cushion block 600 is made to all-in-one-piece benefit and be, can effectively prevent the loss of supporting cushion block 600.
The utility model is illustrated according to embodiment, is not departing under the prerequisite of present principles, and this device can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
