Description

A variable regulation frock for unmanned helicopter paddle pull rod

Technical Field

The utility model relates to a helicopter paddle assembly process, concretely relates to variable regulation frock that is used for unmanned helicopter paddle pull rod.

Background

The blade pull rod used by the helicopter is in the form of two-end joint bearings and a middle connecting rod, and is mainly used for realizing the functions of rotor operation and the like. At present, the pull rod is assembled mainly by a method of a center distance caliper or a fixed distance type tool in the industry. However, the problems of low assembly efficiency, poor consistency of the length of the pull rod, large angular deviation of the knuckle bearing and the like exist in the measurement and assembly of the center distance caliper. The series of problems can have great influence on subsequent helicopter debugging, and can cause unqualified rotor dynamic balance results. In addition, fixed distance formula frock has the problem that can't adjust, if later stage pull rod design change, the frock can't continue to use promptly, causes economic waste.

In order to solve the defects of the existing assembly tool, the tool needs to meet the requirements of variable adjustment, convenient use, safety, reliability, cost reduction and the like, and the variable adjustment tool for the blade pull rod of the unmanned helicopter needs to be designed.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a variable regulation frock for unmanned helicopter paddle pull rod, this variable regulation frock simple structure, small light in weight, low in manufacturing cost can satisfy the pull rod assembly of different angles.

The utility model provides a variable regulation frock for unmanned helicopter paddle pull rod includes:

the integral support I and the split support II are respectively and correspondingly arranged at the joint bearings at two ends of the paddle pull rod, and the support II is provided with a replaceable support head which is used for matching and assembling pull rods of joint bearings with different angles; the base is used for fixing the support I and the support II.

Furthermore, the knuckle bearing on one side of the paddle pull rod is fixed on the head of the support I through a positioning nut, and the knuckle bearing on the other side of the paddle pull rod is adaptive to the head of the support.

Furthermore, the bottom of the replaceable support head is provided with a section of extension part along the vertical direction, and the extension part is fixed on the support II.

Furthermore, the base has been seted up the spout on its length direction, the spout is used for support I and support II to slide.

Further, the base portion is integrally machined.

The utility model has the advantages that: the utility model provides a variable regulation frock for unmanned helicopter paddle pull rod, this frock integrated level is high, simple structure conveniently operates, support accessible spout on the base realizes the regulation of arbitrary distance, later stage update maintains simply; when workers assemble the pull rod, the assembly efficiency can be effectively improved, meanwhile, the length consistency of the pull rod is good, and the angular deviation of the knuckle bearing is small; the tool is small in size, light in weight and low in manufacturing cost, different head tools can be replaced to meet the pull rod assembly at different angles, the design change cost can be effectively reduced, and the economic benefit is improved.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural view of the adjusting tool of the present invention;

fig. 2 shows an example of a tool 1 according to the present invention;

fig. 3 shows an example of a tool 2 according to the present invention.

Detailed Description

As shown in the figure, the utility model provides a variable regulation frock for unmanned helicopter paddle pull rod includes: the integral support I and the split support II 3 are respectively and correspondingly arranged at the joint bearings at two ends of the blade pull rod 7, and the support II 3 is provided with a replaceable support head for matching with pull rods for assembling and debugging the joint bearings with different angles; and the base 4 is used for fixing the support I1 and the support II 3.

In the embodiment, the support head on the split support II 3 is in two forms of a vertical support head 5 and an inclined support head 6, and the support heads are assembled respectively corresponding to two types of pull rods of the unmanned helicopter; the integral support I is divided into a support 1 and a support 2, the support 1 is fixed on the left side of the base 4 through bolts, and the split support II 3 is arranged and fixed at a joint bearing on the other side of the first type pull rod and used for assembling the first type pull rod; and the support 2 is arranged at the position of the right knuckle bearing of the second pull rod according to the fixed position of the support II 3 and is used for assembling the second pull rod. As shown in the figure, if the pull rods at different angles need to be assembled, only the support head needs to be replaced, the position of the support does not need to be adjusted, a worker can assemble the pull rods more conveniently, and meanwhile, the pull rod assembling device is suitable for assembling the pull rods of two types.

In the embodiment, the knuckle bearing at one side of the paddle pull rod is fixed at the head of the support I through a positioning nut, and the knuckle bearing at the other side is adapted to the head of the support head; when assembling the paddle pull rod, only a positioning bolt is needed to fix the knuckle bearing on one side of the pull rod on the head of the support I, and the knuckle on the other side can be adjusted and assembled by utilizing the support head according to requirements.

In this embodiment, the replaceable support head has a section of extension portion at the bottom along the vertical direction, and the extension portion is fixed on the support ii; as shown in the figure, the bottom extension part of the support head is directly inserted into a hole matched with the support II through transition fit to be assembled, a limiting hole used for fixing the support head and the support II is formed in the length direction of the support II, the limiting hole can be a pin hole, and the process is not repeated.

In this embodiment, the base 4 is provided with a sliding groove along the length direction thereof, and the sliding groove is used for sliding of the support i and the support ii; the sliding groove is arranged to meet the requirement that the support can be adjusted on the base according to use requirements, and even if the pull rod with other lengths is replaced, the sliding groove can be used for adjusting and adapting quickly; the tool can be repeatedly used, the cost of design change is effectively reduced, and the economic benefit is improved.

In this embodiment, the base 4 is integrally machined; the base part is simple in structure, only the fixing hole of the support and the support adjusting sliding groove need to be machined, integrated machining is adopted, and manufacturing cost can be reduced.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
