Description
Technical field
The utility model relates to automotive fields, and in particular to a kind of jackshaft gap detection device.
Background technique
Jackshaft is the component for being used to transmit power, and it can change the direction of power or torque transmitting.Its position
In cockpit front bottom end, one end connects the car steering tube column in cockpit, the automobile steering of other end connecting base plate position
Machine.The jackshaft includes intermediate shaft part and two universal joints positioned at intermediate shaft part end, and intermediate shaft part further includes
The first shaft part and the second shaft part mutually slided, namely there are three movement portions in jackshaft.For the smoothness of movement, often
All there is certain movement clearance in a movement portion, but gap is once excessive during assembly, will affect transmission accuracy, simultaneously
Abnormal sound is generated in transmission.
After jackshaft production is completed, need to carry out gap detection, but since the absolute value of drive gap is smaller, and
Since moving component may move during detection, conventional measurer is difficult accurately to measure.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of jackshaft gap detection devices, in precise measurement
Between circumferential gap between axis moving component.
In order to solve the above-mentioned technical problem, a kind of the technical scheme that the utility model is provided is as follows: jackshaft gap detection
Device, including pedestal, the pedestal are equipped with the fixing axle and drive shaft of coaxial arrangement, the fixing axle and drive shaft it
Between formed installation section；It further include at least two detecting tools, the detecting tool includes clamping part and gauge block, the folder
Portion is held equipped with gripping channel；It further include the detection device that gripping channel center rotating angle is surrounded for detecting gauge block.
When being detected, by one end of jackshaft and fixed axis connection and lock, the other end with drive axis connection and lock.
Then the both ends that tooling is mounted on motive position to be detected be will test, due to, with the presence of movement clearance at three, passing through on jackshaft
The installation site for adjusting detecting tool, can successively detect the gap of each motive position, can also be directly installed on fixing axle
In drive shaft, for detecting the integral circumferential movement clearance of countershaft assembly.It is rotated finally by drive shaft driving jackshaft,
By the angle difference of detection two gauge blocks rotation, the circumferential gap angle value of jackshaft is obtained.The detecting tool has structure
Simply, easy to operate advantage.
Preferably, the clamping part includes the first grip block and the second grip block of releasable connection, described first
V-shaped groove is respectively equipped on grip block and the second grip block, V-shaped groove described in two encloses gripping channel jointly.Two V-shaped grooves
Cooperation clamping, not only clamping is reliable, and can effectively clamp to the jackshaft of different-diameter, and applicability is fine.
Preferably, the detection device includes the dial gauge being fixedly connected with pedestal, the test side of the dial gauge
It is arranged with the central axis of gripping channel, the test side of the dial gauge is contacted with gauge block；The test side of each dial gauge is away from folder
The height for holding channel center is equal, is H.
The distance that gauge block is swung at height H is obtained by dial gauge, to obtain the angle value of two pieces of rotations indirectly.By
Smaller in the gap of jackshaft moving component, direct measurement angle variation error is larger.And by the way that height H value is rationally arranged, it can
To play amplification to measured value to a certain extent, and then reduce measurement error.
Preferably, the gauge block is equipped with scale, convenient for the installation and adjustment between dial gauge and gauge block.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present embodiment jackshaft gap detection device；
Fig. 2 is the structural schematic diagram that detecting tool is connect with dial gauge in the present embodiment jackshaft gap detection device；
Fig. 3 the present embodiment jackshaft gap detection device data processing schematic diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment
As shown in Figure 1, a kind of jackshaft gap detection device, including pedestal (are not shown in the figure, are mainly used for supporting each
Detection device), the pedestal is equipped with the fixing axle 5 and drive shaft 4 of coaxial arrangement, between the fixing axle and drive shaft
Form installation section；As shown in Fig. 2, further including at least two detecting tools 2, the detecting tool 2 includes 22 He of clamping part
Gauge block 21, the clamping part 22 are equipped with gripping channel 221；The gauge block 21 is equipped with scale, is convenient for dial gauge 3 and gauge block
Installation and adjustment between 21.
As shown in Fig. 2, the clamping part 22 includes the first grip block 222 and the second grip block 222 of releasable connection, institute
It is respectively equipped with V-shaped groove on the first grip block 222 and the second grip block 222 stated, V-shaped groove described in two encloses clamping jointly
Channel 221.Two V-shaped groove cooperation clampings, not only clamping is reliable, and can effectively clamp to the jackshaft of different-diameter 1, fits
It is fine with property.
As shown in Fig. 2, further including the dial gauge 3 being fixedly connected with pedestal, the test side of the dial gauge 3 and gripping channel
221 central axis setting, the test side of the dial gauge 3 is contacted with gauge block 21；The test side of each dial gauge 3 is logical away from clamping
The height at 221 center of road is equal, is H.
When being detected, by one end of jackshaft 1 and fixed axis connection and lock, the other end with drive axis connection and lock
Tightly.Then the both ends that tooling 2 is mounted on motive position to be detected be will test, due to having at three (A, B, C in Fig. 1 on jackshaft 1
At three) there are movement clearances can successively detect the gap of each motive position by adjusting the installation site of detecting tool 2,
It can also be directly installed in fixing axle and drive shaft, for detecting the integral circumferential movement clearance of 1 assembly of jackshaft.Finally lead to
Axis of overdriving drives jackshaft 1 to rotate, and obtains the distance that gauge block 21 is swung at height H by dial gauge 3, as shown in figure 3, its
In the swinging distance of a dial gauge 3 be denoted as a, the swinging distance of another dial gauge 3 is denoted as b, then to meeting the tendency of on jackshaft 1
The gap width (radian) at dynamic position is △=m-n=arctan (a/H)-arctan (b/H).
Since the gap of 1 moving component of jackshaft is smaller, direct measurement angle variation error is larger.And by being rationally arranged
Height H value can play amplification to measured value to a certain extent, and then reduce measurement error.The detecting tool 2 has
Structure is simple, easy to operate advantage.
Above-described jackshaft gap detection device, between the circumferential direction between precise measurement jackshaft moving component
Gap.
