Abstract
The utility model discloses a clamping mechanism for a circular-ring-shaped member. The clamping mechanism is characterized in that the upper section of a centre rod is configured into a thread rod section which is provided with a nut in a screw-thread fit manner; the centre of a disc-shaped supporting platform is fixed with a boss, and the centre rod is supported on the boss by a rotary bearing; each sliding chute is respectively distributed on the disc-shaped supporting platform along the radial direction in radiation manner by using the centre of the supporting platform as the centre; a sliding rod capable of sliding in the sliding chutes is correspondingly arranged in each sliding chute, the front end of the sliding rod is provided with a stopper connected with the sliding rod as T-shaped; a group of connection rod mechanisms are uniformly arranged on the periphery of the centre rod and correspond to the sliding rod one by one, wherein the boss is used as a supporting piece of the connection rod mechanisms, the nut is used as a driving piece and the sliding rods are used as driven sliding blocks of the connection rod mechanisms. The clamping mechanism is used for fixing the circular-ring-shaped members such as car tires outwards from the circular-ring-shaped centre, so that the clamping mechanism facilitates the maintaining or detecting process.
Description
Technical field
The utility model relates to a kind of clamping device, and a kind of annular member clamping device of more specifically saying so is used for the mechanism that annular member such as doughnut is carried out clamping in the interior week of annular member.
Background technology
In the prior art,, also do not have a kind ofly can outwards carry out stationary device at the center of its annular for doughnut class annulus member, make its repair or testing process in have inconvenience.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of annular member clamping device is provided, being used for doughnut class annulus member is outwards fixed at the center of its annular, to make things convenient for its repairing or testing process.
The utility model adopts following technical scheme for solving its technical problem:
The design feature of the utility model annular member clamping device is to be provided with:
One center-pole, the epimere of said center-pole are the threaded rod section, on said threaded rod section, are provided with nut with threaded engagement;
One support platform in the form of annular discs is provided with a boss in the center fixation of said support platform, and said center-pole is bearing on the boss of said support platform through rolling bearing; On said discoid support platform, be the center with the center of support platform, radially be and penetrate shape and be distributed with each slideway, be equipped with the slide bar that can in slideway, slide in said each slideway, be " T " shape at the front end and the slide bar of said slide bar and be provided with to head;
One group be the umbrella frame shape be evenly distributed on center-pole periphery and with said slide bar each linkage one to one, said linkage is to be support member with said boss, is actuator with said nut, and is by movable slider with said slide bar.
The design feature of the utility model annular member clamping device also is: said each linkage is set to: the periphery that is hinged on boss with an end of first bar; One end of the other end of said first bar and second bar is hinged; The other end of said second bar and said slide bar are hinged; Hinged the 3rd bar at the middle part of said first bar, the other end of said the 3rd bar is hinged on the periphery of nut.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model can be used in doughnut class annulus member is outwards fixed at the center of its annular, is very easy to the location in its repairing or the testing process;
2, the utility model overall structure is the umbrella frame shape and evenly distributes, make the annular member in clamping stressed evenly;
3, the utility model can be used for the different directly annular members of clamping, and adjusting and method for using are simple, operate nimble;
4, the threaded rod section of the threaded engagement in the utility model and nut can be realized lock-bit, make overall structure simpler, use convenient.
Description of drawings
Fig. 1 is the utility model structural representation;
Label among the figure: 1 center-pole; 1a threaded rod section; 2 nuts; 3 support platforms; The 3a boss; The 3b slideway; 4 slide bars; 4a supports head; 5a first bar; 5b second bar; 5c the 3rd bar.
The specific embodiment
Referring to Fig. 1, the design feature of annular member clamping device is in the present embodiment:
One center-pole 1, the epimere of center-pole 1 are threaded rod section 1a, on threaded rod section 1a, are provided with nut 2 with threaded engagement;
One support platform 3 in the form of annular discs is provided with a boss 3a in the center fixation of support platform 3, and center-pole 1 is bearing on the boss 3a of support platform through rolling bearing; On discoid support platform 3, be the center with the center of support platform 3, radially be and penetrate shape and be distributed with each slideway 3b, be equipped with the slide bar 4 that can in slideway 3b, slide among each slideway 3b, be " T " shape at the front end of slide bar 4 and slide bar 4 and be provided with to a 4a;
One group be the umbrella frame shape be evenly distributed on center-pole 1 periphery and with slide bar 4 each linkage one to one, linkage is to be support member with boss 3a, is actuator with nut 2, and is by movable slider with slide bar 4.
As shown in Figure 1; In the practical implementation; Each linkage is set to: be hinged on the periphery of boss 3a with the end of the first bar 5a, the end of the other end of the first bar 5a and the second bar 5b is hinged, and the other end of the second bar 5b and slide bar 4 are hinged; Hinged the 3rd bar 5c at the middle part of the first bar 5a, the other end of the 3rd bar 5c is hinged on the periphery of nut 2.
In the use, through pivot bar 1, nut 2 moves down on center-pole 1; Thereby driving slide bar 4 through linkage moves in slideway 3b; Make to 4 outwards elongations, 4 tightly be pressed on the interior anchor ring of annular member until respectively supporting of being that annular distributes, as be pressed on the interior anchor ring of doughnut; The annular member is formed fixed support, utilize the threaded rod section of threaded engagement and nut to realize lock-bit.Reverse rotation center-pole 1 can solve fixing.
