Description

Technical Field

[0001] The invention relates to the technical field of measuring and checking tools, and more particularly to an adjustable tooth jump detection and checking tool which is convenient for fixing disc parts. Background Art

[0002] At present, every gear needs to be tested for tooth jump after processing, or many disc parts need to undergo this test. Due to the structural characteristics of the gear itself, a mandrel is needed to fix the part during the test. The existing tooth jump test is basically to go to the inspection station, put the gear set on the special tapered mandrel and tighten it, and then use the runout meter to install it between the two centers, and use the probe and dial indicator to detect the gear ring runout of the workpiece.

[0003] However, since the tooth jump detection is a precision measuring instrument, although the dial indicator can measure accurate values, the installation, movement and measurement alignment points of the gears are different, which will still affect the measurement accuracy. Moreover, due to the different core shaft diameters of the gears, different core shafts are required for fixing, which indirectly leads to an increase in the cost of use and low performance.

[0004] Therefore, how to provide a tooth jump detection fixture with strong versatility and high measurement accuracy is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0005] In view of this, the present invention provides an adjustable tooth jump detection fixture which is convenient for fixing disc parts, can realize the detection of gears with various apertures, and has simple operation and high measurement accuracy.

[0038] In order to further optimize the above technical solution, a rubber layer 241 is provided on the arched convex side of the semicircular arc plate 24 .

[0041] In order to further optimize the above technical solution, friction lines are formed on the knob 234 .

[0042] See attached Figure 4 , and also includes a magnetic pop-up mechanism 4, which includes a master control circuit 41, a displacement sensor 42, a magnetic stripe 43, a magnetic connection circuit 44 and a magnetic block 45; the displacement sensor 42 is arranged on the turntable 21 and is electrically connected to the master control circuit 41; a magnetic stripe 43 is arranged around the side of the adjustment seat 22, the magnetic stripe 43 is electrically connected to the magnetic connection circuit 44, and the magnetic connection circuit 44 is electrically connected to the master control circuit 41; the magnetic block 45 is embedded in the arc abutment block 331.

[0043] In order to further optimize the above technical solution, the magnetic strip 43 is embedded in the side wall of the adjustment seat 22 and is flush with its surface.

[0044] The working principle of the present invention is:

[0045] By turning the knob 234 with both hands at the same time, the threaded rod 231 is driven to rotate, so that the two internal threaded sliders 232 move closer to each other, and the semicircular arc plate 24 is driven to move closer until the gear can be inserted into the semicircular arc plate 24 and then stop.

[0046] Insert the gear into the semicircular arc plate 24, and rotate the knob 234 in the opposite direction to move the two semicircular arc plates 24 away from each other until the rubber layer 241 is tightly abutted and fixed with the fixing hole of the gear and then stops.

[0047] According to the size of the gear and the rotation angle, the turntable 21 is rotated for measurement. When the position is found, the fixed seat 32 is pushed toward the turntable to move on the slide groove 1 31 until the arc abutment block 331 is close to the side wall of the adjustment seat 22 and stops. Then the measuring rod 35 is pushed to move on the slide groove 2 34 until the measuring rod 35 contacts the gear for measurement, and the data result of the dial indicator 36 is read.

[0048] When it is necessary to continue measuring, the turntable 21 is rotated. At this time, the displacement sensor 42 receives the rotation signal of the turntable 21 and transmits it to the main control circuit 41. The main control circuit 41 transmits the control signal to the magnetic connection circuit 44. The magnetic connection circuit 44 is turned on, making the magnetic strip 43 magnetic. Since the magnetism of the arc abutment block 331 is the same as that of the magnetic strip 43, the arc abutment block 331 is subjected to thrust, driving the fixed seat 32 to slide in the opposite direction, away from the gear, so as to facilitate the rotation of the turntable 21. Each position adjustment can be completed without manually moving the fixed seat 32.

[0049] The rotating disk 21 is rotated according to the scale of the scale line 211. After the rotation is completed, the above measurement steps are repeated to continue the measurement.

[0050] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
