Abstract
The utility model provides a tighten up diameter adjustable tightening mechanism, a serial communication port, including the right side keep silent (3), a left side keep silent (4), left side rivet (5), right side rivet (9), center rivet (6), right hand handle (7), left hand handle (8), the right side keep silent (3) install on right hand handle (7) through right rivet (9), a left side keep silent (4) install on left hand handle (8) through left rivet (5), right hand handle (7), the middle part of left hand handle (8) articulates integratively through central rivet (6), center rivet (6) are the rotation axis, through the power of mediating, the angle that opens and shuts of adjustment right hand handle (7) and left hand handle (8), the function that thereby it keeps silent to reach tightened up the guard circle, wherein, all be equipped with the boss face on the inner ring that keeping silent (1) in the right side and keeps silent in a left side (4), keep silent (1) and a left side and keep silent the inner ring of (4) and constitute ring shape jointly and tighten up and keep silent in the right side, ring shape is tightened up and is kept silent and the laminating of guard circle (2) outer disc.
Description
Technical field
The present invention relates to a kind of instrument quickly tightening up guard circle。
Background technology
Plastics guard circle is used to stop circular section rubber seal to be squeezed into sealing drum and use in the fit clearance of axle, when plastics guard circle is mounted on axial workpiece, can produce plastic deformation, and what affect axial workpiece is assembled to assembly, it is therefore desirable to tighten up。At present, the conventional mode of tightening up is that tapered sleeve tightens up, but the tapered sleeve of single dimensions can only tighten up the guard circle of a kind of diameter dimension；Meanwhile, in order to avoid tightening up the tapered sleeve destruction to guard circle time, it is necessary to adopting classification to tighten up, the guard circle of a kind of diameter dimension is accomplished by using a series of tapered sleeve。This mode of tightening up needs repeatability to work, and tightener (tapered sleeve) is required height, affects the installation effectiveness of plastics guard circle。For this shortcoming, design one tightens up the adjustable quick tightening system of diameter。
Summary of the invention
The purpose of the present invention: the present invention devises one and tightens up the adjustable tightening system of diameter, this mechanism can realize quickly tightening up function after plastics guard circle is mounted to axial workpiece, and tightening up diameter can according to guard circle diameter adjustment。
Technical scheme: 1. one kind is tightened up the adjustable tightening system of diameter, it is characterized in that, including right jaw (3), left jaw (4), left rivet (5), right rivet (9), center rivet (6), right handles (7), left handle (8), right jaw (3) is arranged in right handles (7) by right rivet (9), left jaw (4) is arranged on left handle (8) by left rivet (5)
Right handles (7), left handle (8) middle part by center rivet (6) be hinged to one; center rivet (6) is rotating shaft; by mediating power; adjust the folding angle of right handles (7) and left handle (8); thus reaching jaw to tighten up the function of guard circle
Right jaw (1) and the internal ring of left jaw (2) are equipped with boss face; the internal ring of right jaw (1) and left jaw (2) collectively constitutes annular and tightens up jaw, and annular tightens up jaw and the laminating of guard circle (2) periphery。
Further, right jaw (1) and left jaw (2) have some different size models, are mounted on right handles (7) and left handle (8)。
Beneficial effects of the present invention: 1) present invention design jaw can change different-diameter, it is achieved different-diameter guard circle be mounted to axle upper postpone quickly tighten up；2) Fast Installation of guard circle can be facilitated, it is to avoid repeatability tightens up the inconvenience that work brings to mounting means, reduce installation difficulty。
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention。
Wherein, 1 axle, 2 guard circles, 3 right jaws, 4 left jaws, 5 little rivets, 6 big rivets, 7 right handles, 8 left handles are installed
Detailed description of the invention
Below in conjunction with diagram, the present invention is described in further detail, refers to accompanying drawing 1。
Accompanying drawings 1; the present invention is after guard circle is mounted to axial workpiece; realize quickly tightening up 1. 1 kinds and tighten up the adjustable tightening system of diameter; it is characterized in that; including right jaw 3, left jaw 4, left rivet 5, right rivet 9, center rivet 6, right handles 7, left handle 8; right jaw 3 is arranged in right handles 7 by right rivet 9, and left jaw 4 is arranged on left handle 8 by left rivet 5
Right handles 7, left handle 8 middle part be hinged to one by center rivet 6, center rivet 6 be rotating shaft, by mediating power, adjusts the folding angle of right handles 7 and left handle 8, thus reaching jaw to tighten up the function of guard circle,
Being equipped with boss face on right jaw 1 and the internal ring of left jaw 4, the internal ring of right jaw 1 and left jaw 4 collectively constitutes annular and tightens up jaw, and annular tightens up jaw and the laminating of guard circle 2 periphery。
Right jaw 1 has some different size models with left jaw 4, is mounted on right handles 7 and left handle 8。
Wherein, the circular jaw that left and right pincers is formed can be changed according to the diameter of guard circle; four little rivets play fixing interconnection function; big rivet is rotating shaft; left and right handle is the applying carrier tightening up moment; by mediating power, and adjust the folding angle of two handles, thus reaching jaw to tighten up the function of guard circle。
Claims (2)
1. one kind is tightened up the adjustable tightening system of diameter, it is characterized in that, including right jaw (3), left jaw (4), left rivet (5), right rivet (9), center rivet (6), right handles (7), left handle (8), right jaw (3) is arranged in right handles (7) by right rivet (9), left jaw (4) is arranged on left handle (8) by left rivet (5)
Right handles (7), left handle (8) middle part by center rivet (6) be hinged to one; center rivet (6) is rotating shaft; by mediating power; adjust the folding angle of right handles (7) and left handle (8); thus reaching jaw to tighten up the function of guard circle
Wherein, right jaw (1) and the internal ring of left jaw (4) are equipped with boss face; the internal ring of right jaw (1) and left jaw (4) collectively constitutes annular and tightens up jaw, and annular tightens up jaw and the laminating of guard circle (2) periphery。
2. according to claim 1 tighten up the adjustable tightening system of diameter, it is characterized in that, right jaw (1) and left jaw (4) have some different size models, are mounted on right handles (7) and left handle (8)。
