The tool clamp is characterized in that a straining cover is fixedly connected with a straining sleeve through a bolt, the straining sleeve is in clearance fit with a straining nut, and a piston connecting rod is connected with the straining nut; the straining cover is in clearance fit with a mandrel, and a spring I is arranged between the straining cover and the mandrel; a slide plate is in clearance fit with a main shaft connecting seat and is arranged on the main shaft connecting seat, one end of the main shaft connecting seat is fixedly connected with a fixed plate through a bolt, the slide plate is provided with a spring II along the axial direction, and the slide plate is provided with a detachable outer sleeve; and one end of the mandrel is provided with a press plate for tightening a compression nut. The tool clamp for turning the large-bore piston ring can simultaneously machine the outer circle and the inner circle of the piston ring on one device and is high in clamping efficiency and clamping precision and low in requirement on operators.
Description
Technical field
The utility model relates to frock clamp, relates in particular to a kind of frock clamp for the big cylinder diameter internal and external circle of piston ring of car.
Background technology
Piston ring is the crux parts in the Diesel engine, and the structure of piston ring, material, process are related to the normal use of diesel engine.And the performance of piston ring has very big influence to diesel engine fuel oil and consumption of lubricating oil.Along with development of science and technology, the needs of environmental protection are more and more higher to the quality requirement of piston ring.
In order to reach new performance, piston ring on structure, material, technology at every moment all in continuous improvement, the piston ring processing technology technology is given birth to thereupon using, and the processing of car inside and outside circle is by original cylindrical turning processing in the big cylinder diameter piston ring, and profiling cylindrical is finally processed.Have following shortcoming:
1, can not carry out cylindrical turning and internal cylindrical turning at same lathe.
2, the machining accuracy of product is low.
The utility model content
The problem that the utility model solves provides a kind of inside and outside circle and processes at an equipment simultaneously, clamping efficient height, and the clamping precision height requires low big cylinder diameter piston ring processing tool to the operator.
For realizing above purpose, the technical solution adopted in the utility model: a kind of frock clamp for the big cylinder diameter internal and external circle of piston ring of car, it comprises tension lid (1), tension cover (2), piston brace rod (3), tightening nut (4), main shaft Connection Block (5), sliding panel (6), fixed head (7), overcoat (9), pressing plate (10), axle (11), clamp nut (12); It is characterized in that: tension lid (1) is bolted to connection with tension cover (2), tension cover (2) and tightening nut (4) matched in clearance, and piston brace rod (3) is connected with tightening nut (4); Tension lid (1) and axle (11) matched in clearance are provided with spring I (16) between tension lid (1) and the axle (11); Described sliding panel (6) is installed on the main shaft Connection Block (5) by matched in clearance, one end of main shaft Connection Block (5) has been bolted to connection fixed head (7), sliding panel (6) in axial direction is provided with spring II (15), and sliding panel (6) is provided with removable overcoat (9); Described axle (11) one ends are provided with by the fastening pressing plate (10) of clamp nut (12).
For preventing axle 11 rotations, under preferable enforcement situation, described axle (11) is provided with anti-switch block (13), and anti-switch block (13) is connected with splicing sleeve (14).
The utlity model has following advantage:
1) the not loose folder of cylindrical turning back piston ring can carry out internal cylindrical turning.
2) product orientation is accurate, has improved product quality.
3) work efficiency is more than doubled.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
In order to make those skilled in the art understand the technical solution of the utility model better; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
As shown in Figure 1, the disclosed a kind of frock clamp for the big cylinder diameter internal and external circle of piston ring of car of the utility model, it comprises, and tension cover 1, tension overlaps 2, piston brace rod 3, tightening nut 4, main shaft Connection Block 5, sliding panel 6, fixed head 7, overcoat 9, pressing plate 10, axle 11, clamp nut 12; It is characterized in that: tension cover 1 and is bolted to connection with tension cover 2, tension cover 2 and tightening nut 4 matched in clearance, and piston brace rod 3 is connected with tightening nut 4; Tension cover 1 with axle 11 matched in clearance, strain cover 1 and axle 11 between be provided with spring I 16; Described sliding panel 6 is installed on the main shaft Connection Block 5 by matched in clearance, and an end of main shaft Connection Block 5 has been bolted to connection fixed head 7, and sliding panel 6 in axial direction is provided with spring II 15, and sliding panel 6 is provided with removable overcoat 9; Described axle 11 1 ends are provided with by the fastening pressing plate 10 of clamp nut 12.
As described in Figure 1, the operation principle of the utility model in practical work process: main shaft connection seat 5 is connected with lathe, in advance be contained in anchor clamps on by pressing plate 10 piston ring 8, manually screw clamp nut 12, relation according to active force and reaction force, axle 11 moves toward the direction near pressing plate 10, covers on 1 owing to spring I 16 acts on to strain, and tension is covered 1 directions with tension cover 2 past close pressing plates 10 and moved.Further piston brace rod 3 is strained backward by hydraulic pressure, axle 11 is moved after by spring I 16 pressure, moves after further driving pressing plate 10, and clamping piston ring 8 carries out cylindrical turning then.Be transformed to the cylindrical location behind the size: overcoat 9 is screwed on the sliding panel 6, and along with the progress increasing of rotation, sliding panel 6 is toward moving near fixed head 7 directions, with the elastic compression overcoat 9 of spring II 15.Piston brace rod 3 is by the hydraulic pressure counter motion, axle 11 is loosening, manually dismantles clamp nut 12, takes out pressing plate 10, immediately piston brace rod 3 is strained backward, thereby tension cover 2 and tension are covered 1 and are compressed sliding panel 6, and piston ring 8 carries out internal cylindrical turning after compressing by overcoat 9.
Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.The above only is preferred embodiment of the present utility model, should be understood that, because the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be made up by rights; These improve retouching, change or combination, or without improving the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
