Abstract
The utility model provides a special joint for a tensile inspection of a roller chain. The special joint comprises an internal chaining joint and an external chaining joint, wherein the internal chaining joint is in the shape of reversed H, with left and right sections provided with internal chain plate inlets; holes with mutually corresponded positions are opened at two sides of the internal chain plate inlet; the diameters of the holes are more than the diameter of a pin roll of the roller chain; the external chaining joint is a solid, with left and right sides structured as two parallel planes; the space between two planes is less than the inside diameter of the external chain of the roller chain; two holes are lengthways distributed on the external chaining joint along the vertical directions of the left and right sides; the diameters of two holes are more than the diameter of the pin roll of the roller chain. In the special joint for the tensile inspection of the roller chain, the inspection to the internal chaining and the external chaining can be respectively carried out, so that the inspection efficiency is improved; the quantity of used fabricated parts required in inspection can be reduced, and the cost is reduced thereby.
Description
Technical field
The utility model provides a kind of roller chain tension check special joint, specifically is used for the inner link of check roller chain on puller system and the tensile strength of outer link.
Background technology
Short pitch roller chain is in the routine inspection project, and tensile load is its key index.When existing product is detected; No matter be check inner plate, pin link plate or bearing pin; All need part be dressed up 5 finished product chains more than the chain link and test, in long-term checkout procedure, exist following problem: because the chain kind that professional chain manufacturer produces is a lot, the inner plate in the same kind, pin link plate or bearing pin can not be come out of the stove simultaneously; So just need repeatedly be assembled into the above chain of 5 joints and carry out the pulling force check; Spended time is long, because the chain that carried out after the pulling force check can not reuse, has so just also caused the waste of chain part again.
Summary of the invention
The utility model provides a kind of roller chain tension check special joint, has solved shortcomings such as the low and waste finished product chain part of the checkability that in the tension check to short pitch roller chain, occurs.
Realize that the technical scheme that the utility model above-mentioned purpose is adopted is:
A kind of roller chain tension check special joint; Comprise inner link joint and outer link joint; The inner link joint is an I shape, and two sections are equipped with the inner plate access port about it, and the both sides of inner plate access port all have the hole; The position in two holes is corresponding each other, and the diameter in hole is greater than the diameter of the bearing pin of roller chain; The outer link joint is a solid; Its left and right sides face is two planes that are parallel to each other; Distance between two planes is less than the inner width of the outer link of roller chain; Have two holes that front and back distribute along the direction vertical with left and right sides face on the outer link joint, the aperture in two holes is greater than the pin diameter of roller chain.
Distance between two holes on the outer link joint is identical with the pitch-row of the pin link plate of roller chain.
The material of outer link joint and inner link joint is 40Cr.
The roller chain tension check special joint that the utility model provides has following advantage: the inner link joint is used for checking the tensile strength of inner plate; The tensile strength of outer link joint test pin link plate and bearing pin; Each part of chain is separately detected; Need each part be assembled into whole chain and detect, improve checkability, also reduce the waste of finished product chain part simultaneously.

Fig. 4 is the working state schematic representation of outer link joint;
Among the figure, 1-inner link joint, 2-outer link joint, 3-inner plate, 4-pin link plate, 5-bearing pin.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The structure of the roller chain tension check special joint that the utility model provides is as depicted in figs. 1 and 2, and inner link joint 1 is an I shape, and two sections are equipped with the inner plate access port about it, and the width of inner plate access port is greater than the thickness sum of two inner plates 3.The both sides of inner plate access port all have the hole, and the position in two holes is corresponding each other, and the diameter in hole is as shown in Figure 1 greater than the diameter of the bearing pin of roller chain.Outer link joint 2 is block solid; Its left and right sides face is two planes that are parallel to each other; Distance between two planes is less than the inner width of the outer link of roller chain; Have two holes that front and back distribute along the direction vertical with left and right sides face on the outer link joint, the aperture in two holes is greater than the pin diameter of roller chain, and the distance between two holes is identical with the pitch-row of the pin link plate of roller chain in the present embodiment.
The duty of inner link joint is as shown in Figure 3; All be placed with two range upon range of inner plates 3 in the inner plate access port; Because the axis hole of inner plate 3 is bigger than the diameter of bearing pin, so the bearing pin that inserts in the hole of the both sides of inner plate access port is used bearing pin in the big model chain.After 1 circulation is connected in series more than 5 joints with the inner link joint with inner plate 3, put into its tensile load of pulling force checking machine check, accomplish the detection of inner plate.
The duty of outer link joint is as shown in Figure 4; Bearing pin 5 passes hole on the outer link joint and is fixed between two pin link plates 4 and forms outer link; After circulation is connected in series more than 5 joints with outer link with outer link joint 2; Put into its tensile load of pulling force checking machine check, accomplish the detection of pin link plate and bearing pin.
The material of outer link joint 2 and inner link joint 1 is 40Cr, and its tensile strength is very high, can satisfy the tension test requirements to roller chain fully.
The roller chain tension check special joint that the utility model provides assigns to the check of inner link and the check of outer link to accomplish, and has improved checkability; Reduce the use amount of required fabricated part in the checkout procedure simultaneously, practiced thrift cost.
