Description
Technical field
It the utility model is related to robotic technology field, and in particular to a kind of arm for articulated robot and corresponding
Articulated robot.
Background technology
As shown in figure 1, articulated robot 100 can include the first arm 101 and the second arm 102.The top of first arm 101
There can be two protuberances 105 and 106, the two protuberances are almost parallel.The bottom of first arm can include hollow branch
Support member 103, it can be used for carrying the equipment such as motor.Second arm 102 be pivotally connected to two protuberances 105 and 106 with
So that the second arm 102 is supported by two protuberances and the second arm 102 0 can be rotated around the shaft.
Generally, the casting of the first arm can use sand casting or compression casting.Compression casting has dimensional accuracy and steady
The advantage of qualitative aspect, casting cost are relatively low.
But as shown in Fig. 2 for having cave inward position 201 to be cast part as the first arm 101, when
When casting is completed, casting mould 202 can not be taken out.Also, in order to store necessity of the robots such as gear, timing belt, cable
Component, the first arm 101 would generally be designed to hollow shape, and such shape also results in casting completion can not with rear mold 202
Take out.
Due to above-mentioned technical problem be present, in the first arm 101 of manufacture machine people, sand is generally used in the prior art
Mold casting.But the preponderance of obtained the first arm of sand casting, dimensional accuracy be not high, manufacturing expense is also higher.
In order to use compression casting, as shown in fig. 7, prior art further discloses the first arm 101 is passed through into divisional plane
P1 is divided into two half mould portions 701 and 702 and distinguishes die casting, again connects together two half mould portions to obtain complete first arm afterwards
101.But the shape of two half mould portions 701 and 702 in the prior art is symmetrical, also, the support member of the first arm bottom
Also it has been divided in two half mould portions.This just needs to need to adjust its position in four direction when connecting two half mould portions,
So as to which the precision for causing connection to be installed is difficult to be guaranteed.In addition, support member be divided can cause the mechanical performance of support member by
To influence.

It is specific below in conjunction with the utility model to make the purpose of this utility model, technical scheme and advantage clearer
Technical solutions of the utility model are clearly and completely described for embodiment and corresponding accompanying drawing.Obviously, described embodiment
Only it is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, this area
The every other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to the utility model
The scope of protection.
With reference to figure 3 and Fig. 4, the arm 101 for articulated robot can be by the first half mould portion 301 and the second half mould portion
302 be combined with each other and are formed, the top in the top in the first half mould portion 301 and the second half mould portion not Ju You protuberance 105 and 106,
Protuberance 105 and 106 almost parallel.Protuberance 105 and 106 can form U-shaped.
The bottom in the first half mould portion 301 can have complete support member 103, i.e.,：Support member 103 is entirely located in the first half
The bottom in type portion 301.This can ensure that support tube 103 is intactly cast.Support member 103 can be in hollow cylindrical shape or
Person is in other hollow shapes.
Two half mould portions can be combined by faying face 303, and faying face 303 can be located at two protuberances 105 and 106
Between.Here and hereinafter, composition surface refers to contact with each other face or phase of two half mould portions 301 and 302 when combining
Mutually close to face, it can be completely attached to, it is possibility to have appropriate gap, it can be plane or curved surface.
According to one embodiment of the present utility model, composition surface 303 can be generally parallel to protuberance 105 and 106
Projected direction and to the unequal plane of distance of two protuberances.The projected direction Y of protuberance 105 and 106 can be in Fig. 3
Shown dotted arrow direction.The volume of part of the thus obtained two half mould portions in addition to support tube can also be unequal.
In the case, as shown in figure 5, according to one embodiment of the present utility model, support tube 103 can be entirely located in two half moulves
Except in the larger half mould portion 301 of the outer volume of support tube, this can cause the mechanical performance of support tube 103 more preferably in portion.
The shape of the bottom 304 in the second half mould portion 302 can match with the shape of the periphery of support member 103.Need strong
Adjust, " matching with the shape of the outer peripheral face of support member 103 " mentioned here, refer to the bottom in the second half mould portion 302
304 shape, which needs only assure that, will not cause when the first half mould portion 301 to be connected and combine with the second half mould portion 302
One half mould portion 301 and the second half mould portion 302 mutually contradict and can not combined, and are not necessarily to the second half mould portion 302
Bottom 304 connect with being shaped such that between the first half mould portion and the second half mould portion complete tight.Such as：Work as support member
When 103 periphery is cylindrical shape, the shape of the bottom 304 in the second half mould portion 302 can be arc surface or plane or
The curved surface of other shapes, as long as the plane or other shapes curved surface will not cause by the first half mould portion 301 and the second half mould portion
302 connections are mutually contradicted and can not be installed in place when combining, even if the first half mould portion 301 and the second half mould portion
302 be installed in place after have space also possible between the two.
The periphery of the support member 103 in the first half mould portion 301 obtained by above-mentioned means die casting is complete.In order to
Vertical direction of the equipment that cable, timing belt etc. are located in arm along arm is facilitated to walk setting, as shown in Figure 5 and Figure 6, can also be
After the completion of die casting, the upper outer peripheral face of support member 103 is got rid of at least in part using process equipments such as Digit Control Machine Tools, to be formed
Cable, timing belt can be made to be passed out of support tube to enter the through hole 501 of the hollow space in the first half mould portion 301.Support member
103 upper outer peripheral face refer on outer peripheral face towards the first half mould portion 301 hollow space outer peripheral face.
Because two half mould portions 301 and 302 have above-mentioned feature, pressure can either be passed through by allowing for arm of the present utility model
Casting obtains, and fork can strengthen the mechanical performance of support member therein, moreover it is possible to easily carries out hollow processing to arm.
Embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this area
Technical staff for, the utility model can have various modifications and variations.It is all within the spirit and principles of the utility model,
Any modification, equivalent substitution and improvements made etc., it should be included within right of the present utility model.
