Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As depicted in figs. 1 and 2, according to specifically comprising of the error prevention device of the air compressor machine joint direction of rotation of the utility model detailed description of the invention: contiguous block 3, scale plate 5, fork 4, fork screw 6 and pendulum 1, wherein, one end of contiguous block 3 is inserted in the joint 8 of air compressor machine 7, the center line of joint 8 and air compressor machine 7 is made to have angular relationship, scale plate 5 is fastened on the other end of contiguous block 3, and scale plate subscript had often once been marked with 0 degree to 90 °, was accurate to 0.5 degree.Fork 4 is fixed on scale plate 5 by fork screw 6, and pendulum 1 is located in the end (lower end) of fork 4.One end of the contiguous block 3 of the error prevention device of this air compressor machine joint direction of rotation is inserted in the joint 8 of air compressor machine 7, the center line of joint 8 is equal with pendulum indication number of degrees on dial with air compressor machine 7 angulation, such can ensure air compressor machine joint installation quality, the normal operation that improves productive temp, ensure error prevention device, really play the effect of mistake proofing, ensure the assembly quality of product.
As shown in Figure 3 and Figure 4, one end of contiguous block 3 has the cylindric plug with the adaptive grafting of joint 8 of air compressor machine 7, this cylindric plug and joint 8 matched in clearance, after inserting joint 8, make the center line of joint 8 and air compressor machine 7 angulation transformation be contiguous block 3 and air compressor machine 7 angulation relation, the center line of such as figure center tap 8 and air compressor machine 7 become 60 ° of angles.The other end of contiguous block 3 has scale plate bayonet socket and runs through the bolt hole of this scale plate bayonet socket, and a side of scale plate 5 is inserted in this scale plate bayonet socket, then is fixed through bolt hole by hexagon socket cap head screw.Preferably, this bolt hole is two that are arranged side by side.
As shown in Figure 5, scale plate 5 subscript is marked with the curved scale of 0 degree to 90 degree, and is accurate to 0.5 degree.Preferably, scale plate 5 is square, and central authorities have lightening hole.Fork screw 6 is spirally connected the circle centre position of the curved scale being fixed to scale plate 5, and as shown in Figure 6 and Figure 7, the head of fork screw 6 has fork perforation, and two ports of this fork perforation have ball-and-socket.One end of fork 4 has backstop head, and the inner of this backstop head has the bulb that the port ball-and-socket type of boring a hole with fork becomes sphere-contact; As shown in Figure 8 and Figure 9, pendulum 1 is coniform, has axial through bore, is located in the other end of fork 4 by this axial through bore.
