The specific embodiment
Core of the present utility model provides a kind of positioning tool that is used for rotary handle spring assembling, and this tool structure is simple, rationally, and operation is reliable, thereby can effectively save the assembler time, and improve product percent of pass greatly.
Specify present embodiment below in conjunction with Figure of description.
The related herein noun of locality such as upper and lower, interior and outer is that to close with the position shown in Fig. 1 be the benchmark definition, should be appreciated that the application of the described noun of locality such as upper and lower, interior and outer does not limit the scope that the application asks for protection.
See also Fig. 1 and Fig. 2, wherein, Fig. 1 is the front view of the described rotary handle spring assembling of present embodiment with positioning tool, and Fig. 2 is the D-D cutaway view of Fig. 1.
The positioning tool of rotary handle spring assembling comprises support 1, balance weight body 2, two claws 3, two wedge-shaped catch 4, two positive stops 5 and stick control mechanisms 6.
Wherein, support 1 have lower shoe 11, upper cover plate 12 and place lower shoe 11 and upper cover plate 12 between four leads 13; On balance weight body 2 suits and the lead 13, and this balance weight body 2 can be along lead 13 upper and lower slips.Use to understand, the quantity of lead 13 is not limited to four shown in the figure, and in fact, it also can be a plurality of for other of at least two, use needs all can as long as satisfy.In addition, the lower shoe 11 of support 1 is provided with positioning boss 14; After two claw 3 closures, two relative indent arcuation grain-clamping table terraces 31 and these positioning boss 14 centerings are so that the radial location of spring to be assembled.
One end of two claws 3 is hinged with balance weight body 2 respectively, and the lower surface of the other end of two claws 3 has the indent of being oppositely arranged arcuation grain-clamping table terrace 31, is used for matching with fixed part on the spring.
Two wedge-shaped catch 4 are separately positioned on the outside of described two claws 3, and the big up and small down wedge shape in the bottom of two wedge-shaped catch 4; Two positive stops 5 are fixedly installed on respectively on the lower shoe 11 of support 1; During practical operation, the lateral surface of two wedge-shaped catch 4 cooperates with the inboard of two positive stops 5 respectively.
Intermediate position as shown in Figure 3 and Figure 4.Balance weight body 2 along lead 13 when the lower slider, the lower wedge of two wedge-shaped catch 4 is subjected to the left and right restriction of described two positive stops 5 respectively to intrinsic displacement, and promote two claws 3 respectively and inwardly turn to closure state respectively, so that realize the location of spring to be assembled.As shown in Figure 5 and Figure 6 compress the operating position.When balance weight body 2 continued to lower slider along lead 13, two claw 3 servo-actuateds also pressed down, so that realize the precommpression of spring to be assembled.
Particularly, the position matching between two wedge-shaped catch 4 and the adjacent component can be selected multiple design for use, is slidingly matched with the lower surface of balance weight body respectively such as, two wedge-shaped catch, and promptly itself and claw connect; Perhaps, described two wedge-shaped catch are fixedlyed connected with two claws respectively.
Need to prove, two positive stop 5 preferred roller bearings that adopt, its inner ring is fixed, foreign country is used for matches with wedge-shaped catch 4, and then makes that operation is more smooth and easy, improves the operability of described frock.
From the whole assemble flow of rotary handle, the assembling of spring is one of them operation, and on the actual production line, it is very compact that the work between each operation is connected, and therefore, need improve the operating efficiency of spring assembling to greatest extent.
For this reason, the described positioning tool of this programme also comprises and is arranged at two Flexible Reset parts 7 between the claw 3; Like this, when lower slider and two claws 3 were closed, these Flexible Reset parts 7 stress deformations were when upwards slide along lead 13 by balance weight body 2 along lead 13 for balance weight body 2, under the effect of the elastic deformation energy of these Flexible Reset parts 7, two claws 3 outwards turn to open mode.Thereby enter operation SBR next time, in the time of can further reducing the assembler.Should be appreciated that Flexible Reset parts 7 can select stage clip, extension spring or elastic caoutchouc for use.
In like manner, also can there be the mode of multiple realization in stick control mechanism 6 based on prior art.As shown in the figure, stick control mechanism 6 comprises connecting rod 61, push rod 62 and handle 63; Hinged attached seat 121 on the upper cover plate 12 of the lower end of connecting rod 61 and support 1 is articulated in the first hinge A; The lower end of push rod 62 is passed upper cover plate 12 and is fixedlyed connected with balance weight body 2; Handle 63 is articulated in the second hinge B, tri-joint mechanism C with the upper end of connecting rod 61 and push rod 62 respectively; And handle 63 and connecting rod 61 pin joints (the second hinge B) to the distance between handle 63 and push rod 62 pin joints (tri-joint mechanism C) less than handle 63 and connecting rod 61 pin joints (the second hinge B) to the distance between connecting rod 61 and hinged attached seat 121 pin joints (the first hinge A).The purpose of design like this, to limit the initial position of this frock, concrete operation principle is: when this frock was handled off working state, aforementioned three hinges set gradually (dead-centre position) from top to bottom, to overcome balance weight body 2 deadweights; During operating grip 63, handle 63 drivening rods 61 upper ends are to lateral deviation commentaries on classics and then depart from aforementioned dead-centre position, like this, rely on balance weight body 2 deadweights can finish claw 3 clampings, pressing action.
The operating sequence of the described positioning tool of brief description present embodiment:
One, with spring to be assembled 20 and go up fixed part 30, fixed part 40 places on the lower shoe 11 of support 1 successively down.
Two, pull stick control mechanism 6, make handle 63 drivening rods 61 upper ends change to a lateral deviation, at this moment, balance weight body 2 under the effect of its deadweight along lead 13 to bottom offset, two wedge-shaped catch 4 are subjected to the restriction of positive stop 5 respectively to intrinsic displacement, and drive two claws 3 and inwardly rotate, fixed part 30 on the spring is blocked on its indent arcuation grain-clamping table rank 31, two claw 3 closed backs; The claw 3 of two closures continues to press down spring to be assembled 20 to design attitude.
Three, as shown in Figure 5, pulling handle 63 to opposite horizontal level locks.At last, carry out the assembling that terminal operation is finished spring.Oppositely pull stick control mechanism after assembling is finished, can spur balance weight body 2 and upwards be moved to initial position along lead 13.
To sum up, the utlity model has rational in infrastructure, operate reliable advantage, once-through operation can be finished two actions of location, precommpression of spring, can enhance productivity greatly.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
