Two kinds of methods of inspection, various pendulum impact test devices on the market are also to be designed according to the requirement of standard at present.
Simplest balance weight impact testing machine is exactly the angle for manually changing oscillating rod, it is obtained kinetic energy, then
Decontroling oscillating rod makes it freely swing and impact by experimental rig, so as to obtain test data.Such as utility model patent
（CN204535948U）, a kind of pendulum impact test device is disclosed, the height of oscillating rod is calculated by graduated scale, so that complete
Into experiment.
Either change angle and still change dimensional height, existing experimental rig is all manually to operate both ends, is made
It coordinates because it is artificial the reason for cause test data that very big error occurs, and because two hands operations can cause
It is very inconvenient during experiment, it has to which that two people's operations are once tested, and efficiency is very low, it is therefore necessary in existing mark
Made improvements on the basis of standard.
Utility model content
The purpose of this utility model is to provide a kind of pendulum impact test device, it is precisely obtained when changing angle
Take angle, and reliable and stable completion pendulum impact test.
To achieve these goals, the utility model uses following technical scheme：
A kind of pendulum impact test device, including a supporting rack, crossbeam, the horizontal stroke are vertically installed with supporting rack plane
Fixed seat is provided with supporting rack below beam, swinging base and oscillating rod are provided with the crossbeam, oscillating rod includes mutual
The cross bar and montant being vertically fixedly connected, one end of the montant are provided with pendulum, and the both ends of cross bar are connected respectively on pedestal
Bearing hole in, be provided with rotatable angle slide calliper rule on the swinging base, the rotation of the cross bar of oscillating rod in angle slide calliper rule
In the range of rotate.
In the above-mentioned technical solutions, the angle slide calliper rule include a rotating mechanism, and the rotating mechanism, which passes through, to be swung
The side of pedestal is sleeved on one end of cross bar.
In the above-mentioned technical solutions, the block of protrusion, block are provided with the rotating mechanism inner wall being sleeved on cross bar
Pointer with rotating mechanism slide calliper rule is in the same side.
In the above-mentioned technical solutions, the rotating angle of the block is identical with the rotating angle of pointer, and block is same with pointer
Step rotation.
In the above-mentioned technical solutions, it is inserted on the side of the cross bar of rotating mechanism and is fixedly installed the locating part of protrusion.
In the above-mentioned technical solutions, the stop location that the locating part of the protrusion is protruded with rotating mechanism inner wall matches.
In the above-mentioned technical solutions, the both sides on the crossbeam are provided with slideway, and the swinging base is stuck in slip, pendulum
Moving base is slided relative to crossbeam.
Compared with prior art, its advantage is the utility model：The mark in traditional Charpy impact device is canceled
Slide calliper rule are spent, but angle reading mechanism is combined into one with swing rod, pass through the setting of cleverly position limiting structure so that only need to put
Driven fork can be achieved with the adjustment of angle to corresponding position, and an operator just can easily complete entirely to test, Er Qieyin
Adjusted to employ rotation angle so that angle precision higher, operation are more convenient.

Fig. 3 is the structure diagram of rotating mechanism and cross bar；
Wherein：1 is supporting rack, and 2 be fixed seat, and 3 be crossbeam, and 4 be swinging base, and 5 be oscillating rod, and 5-1 is montant, 5-2
It is cross bar, 6 be rotating mechanism, and 7 be block, and 8 be locating part.
Embodiment
As shown in Figure 1, the obvious different place of the pendulum impact test device and traditional device of the utility model exists
In having canceled the bar that sets scale, the pendulum impact test device of the application includes a supporting rack, on shown supporting rack
Fixed seat is provided with, crossbeam is vertically installed with the supporting surface of supporting rack, is provided with swinging base on crossbeam, on swinging base
It is connected with oscillating rod.The fixed seat is arranged on the lower section of crossbeam, the center of the pendulum face fixed seat on oscillating rod, from
And to realize swing test.
As shown in Fig. 2, be the oscillating rod of the utility model, oscillating rod includes two parts, montant and cross bar, the one of montant
End is connected with pendulum, and for being hit with measured object, and the other end of montant is connected with cross bar, and montant is one day with cross bar
Structure.The rotation process of montant drives cross bar to rotate, and the both ends of cross bar are connected respectively on swinging base.
The swing angle of the oscillating rod of the utility model mainly by the rotation angle slide calliper rule that are arranged on swinging base come
Determine, rotation angle slide calliper rule include a rotating mechanism, are realized using the structure similar to knob, are set on the side of knob
There are some angle marks, and a pointer is provided with rotating mechanism, some scale is directed toward by rotating pointer.And
Finite place piece is set on the internal face of rotating mechanism, and on the same line, the rotating angle of pointer is equal to for locating part and pointer
The rotating angle of locating part.Then montant synchronous drive cross bar in rotation process rotates, and the angle that montant rotates is led to
Cross the rotating angle of cross bar and quantify to realize.
In order to ensure an accurately angle, as shown in figure 3, block is provided with the side of one end of cross bar first,
Block rotates together with cross bar.Block on cross bar is mutually matched with rotating mechanism upper limit part, and locating part plays position restriction
Effect, it is ensured that the angle that cross bar rotates.
Actual operating process is, when needing to test some article, to calculate the momentum of its pendulum first, so that according to dynamic
Measure to calculate the height and angle of pendulum.After determining angle, rotating mechanism is manually twisted so that its pointer is directed toward certain
One angle, locating part can also follow and rotate corresponding angle together during rotating.Because rotating mechanism is using current
General structure, rotates to the function with automatic positioning locking behind a certain position, therefore locating part can also be fixed on a certain position
Put.Then montant can be swung, montant drives cross bar to rotate, and the block on cross bar can also follow rotation, when block turns to
During the position of locating part, it cannot be rotated further, also surface montant turns to corresponding angle, decontrols montant by its freely falling body
The shock of pendulum and tested article is can be achieved with, so as to complete to test.
