Description
Technical field
The utility model belongs to the devices field that fastening or fixed component or machine parts are used, and is specifically related to a kind of rotary blade and repairs clamping device.
Background technology
Rotary cultivator is the driving soil cultivating machine taking rotary cutter tooth as workpiece, because of its have hack ability strong, plough after the features such as earth's surface is smooth, and be widely used.Rotary blade part in rotary cultivator is the structure of hack, and rotary blade is easy to blunt in hack process, even occurs breach, so will repair rotary blade, in repair process, will first rotary blade be fixed, so conventionally will use clamping device.
Existing have two clamping heads conventionally for clamping the clamping device of rotary blade, and cam or connecting rod often will be set, although can reach the object of clamping rotary blade, more complicated in structure.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of rotary blade to repair clamping device, and this clamping device is without cam or connecting rod are set, simple in structure, and can reach the object of clamping rotary blade locking.
For achieving the above object, the technical solution of the utility model is: rotary blade is repaired clamping device, comprise support, left pressing plate and right pressing plate, described left pressing plate and right pressing plate upper end are equipped with clamping gib head, lower end is all rotationally connected with on support, and two clamping gib head positioned opposite, wherein, also be provided with drive rod, compressor arm, spacer pin and back-moving spring, described back-moving spring is located between left pressing plate and the inner side of right pressing plate; Described drive rod one end is articulated with the middle part of right pressing plate, and the other end is positioned at left pressing plate outside, and described compressor arm vertical drive pole length direction runs through drive rod, and offsets with the outside of left pressing plate, and described drive rod and compressor arm are provided with the spacing hole that coordinates spacer pin; The outside of described left pressing plate is to coordinate compressor arm to compress the round slip surface of left pressing plate.
While adopting technique scheme, rotary blade is positioned over to frame upper surface, because the outside of compressor arm and left pressing plate offsets, and the outside of described left pressing plate is the round slip surface that coordinates compressor arm to compress, pull drive rod free end, make compressor arm towards right pressing plate one side compression left pressing plate, the other end of drive rod and right pressing plate middle part are hinged again, so, two pressing plates all rotate around the pin joint of lower end, pendulum in upper end, the clamping gib head that is arranged at left pressing plate and right pressing plate upper end clamps rotary blade, remove and put on after the free-ended active force of drive rod, round slip surface auto lock two pressing plates in the outside of left pressing plate.The utility model, without cam or connecting rod are set, only becomes round slip surface by the arranged outside of left pressing plate, simple in structure, but can reach the object of clamping rotary blade locking.
Further, described compressor arm is slidably connected with it along drive rod length direction, and drive rod length direction is provided with multiple spacing holes, so just can clamp the rotary blade of different size; In addition, along with the wearing and tearing in compressor arm and left pressing plate outside, by regulating the position of compressor arm on drive rod, can eliminate wearing and tearing.
Further, the surface that described left pressing plate outside contacts with compressor arm is provided with wearing layer, and the friction in compressor arm and left pressing plate outside is frequent, and wearing layer can delay the wearing and tearing in left pressing plate outside.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model rotary blade is repaired clamping device embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of rotary blade is repaired clamping device, comprise support 1, left pressing plate 3 and right pressing plate 2, left pressing plate 3 and right pressing plate 2 upper ends are equipped with clamping gib head, lower end is all rotationally connected with on support 1, and two clamping gib head positioned opposite, wherein, also be provided with drive rod 5, compressor arm 6, spacer pin 4 and back-moving spring 7, back-moving spring 7 is located between left pressing plate 3 and the inner side of right pressing plate 2; Drive rod 5 one end are articulated with the middle part of right pressing plate 2, and the other end is positioned at left pressing plate 3 outsides, and compressor arm 6 vertical drive bar 5 length directions run through drive rod 5, and offset with the outside of left pressing plate 3, and drive rod 5 and compressor arm 6 are provided with the spacing hole that coordinates spacer pin 4; The outside of left pressing plate 3 is to coordinate compressor arm 6 to compress the round slip surface of left pressing plate 3, and this round slip surface is similar to the surface of cam, and left pressing plate 3 outer upper end to the radius of lower end increases gradually.
In the present embodiment, compressor arm 6 is slidably connected with it along drive rod 5 length directions, and drive rod 5 length directions are provided with multiple spacing holes, so just can clamp the rotary blade 8 of different size; In addition, along with compressor arm 6 and the wearing and tearing in left pressing plate 3 outsides, by regulating the position of compressor arm 6 on drive rod 5, can eliminate wearing and tearing.Left pressing plate 3 outsides are provided with wearing layer with the surface that compressor arm 6 contacts, and compressor arm 6 is frequent with the friction in left pressing plate 3 outsides, and wearing layer can delay the wearing and tearing in left pressing plate 3 outsides.
Specific works flow process:
As shown in Figure 1, the clamping gib head that is illustrated as left pressing plate 3 and right pressing plate 2 is in clamping the state of rotary blade 8.Rotary blade 8 is positioned over to support 1 upper surface, and because compressor arm 6 and the outside of left pressing plate 3 offset, and the outside of left pressing plate 3 is the round slip surface that coordinates compressor arm 6 to compress, and left pressing plate 3 outer upper end to the radius of lower end increases gradually.Pull drive rod 5 free ends downwards, make compressor arm 6 towards right pressing plate 2 one side compression left pressing plates 3, the other end of drive rod 5 and right pressing plate 2 middle parts are hinged again, so two pressing plates all rotate around the pin joint of lower end, pendulum in upper end, the clamping gib head that is arranged at left pressing plate 3 and right pressing plate 2 upper ends clamps rotary blade 8 jointly, remove and put on after the free-ended power of drive rod 5, round slip surface auto lock two pressing plates in the outside of left pressing plate 3, now back-moving spring 7 is compressed.Upwards pull drive rod 5 free ends, back-moving spring 7 outwards promotes two pressing plates, and the clamping gib head on left pressing plate 3 and right pressing plate 2 unclamps rotary blade 8.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
