[0002] The middle of a long pull rod is cylindrical, one end is a square or regular hexagon with opposite side dimensions slightly larger than the diameter of the middle cylinder, and one end is a cylinder slightly larger than the diameter of the middle cylinder. On this cylinder, there is a round hole passing through the axis of the pull rod and perpendicular to it. The axis of this round hole forms a small angle of several degrees with the square or regular hexagon at the other end, and the angular tolerance is very small.

[0003] Traditional testing methods can use auxiliary inspection tools for testing on a coordinate measuring instrument, but the testing is time-consuming, laborious, and the efficiency is extremely low, unable to meet the inspection requirements for mass production.

[0004] Therefore, there are defects in the prior art and improvement is needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an efficient pull rod angle detection device.

[0006] The technical solution of the present invention is as follows: An efficient pull rod angle detection device includes a basic installation component, an angle sensing component, a test head, a positioning component, and a positioning pin;

[0007] The basic installation component is used to install the angle sensing component, the positioning component, and the positioning pin.

[0012] The spring is located in the middle of the adjusting bolt. The supporting block is provided with a spring groove. One end of the spring abuts against the spring groove, and the other end of the spring abuts against one end of the adjusting bolt close to the pressing block.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] As Figures 1 to 5 shown, this embodiment provides an efficient pull rod angle detection device, including a basic installation component 1, an angle sensing component 2, a test head 3, a positioning component 4, and a positioning pin 5.

[0026] The basic installation component 1 is used to install the angle sensing component 2, the positioning component 4, and the positioning pin 5. One end of the angle sensing component 2 is connected to an external display component, and the other end of the angle sensing component 2 is connected to the test head 3. The angle sensing component 2 can rotate synchronously with the test head 3, and then transmit the rotation angle to the external display component, and the external display component displays the angle value.

[0027] The positioning component 4 is used to fix the middle part of the pull rod 6 to be tested to ensure that the pull rod 6 to be tested does not deform during the rotation process. The positioning pin 5 is used to pass through the round hole at one end of the pull rod 6 to fix the bottom of the pull rod 6 to be tested. One side of the other end of the pull rod 6 to be tested is in close contact with the front surface of the test head 3, so that the test head 3 rotates synchronously with the contact surface of the pull rod 6 to be tested.

[0028] Figure 2 and Figure 3 are structure diagrams of the head of the pull rod 6 to be tested with a square shape, Figure 4 and Figure 5 are structure diagrams of the head of the pull rod 6 to be tested with a hexagonal shape. The difference between the two is that Figure 2 and Figure 3 in, the surface of the test head 3 in contact with the pull rod 6 to be tested is a plane, Figure 4 and Figure 5 in, the surface of the test head 3 in contact with the pull rod 6 to be tested is a concave surface.

[0029] Taking Figure 2 and Figure 3Taking it as an example, the basic installation component 1 includes a bottom plate 11, a top plate 12, a support block 13 and two rib plates 14. One end of the bottom plate 11 is fixed to the top plate 12, and the bottom plate 11 and the top plate 12 are perpendicularly arranged. The angle sensing component 2 is fixed on the top plate 12. The two rib plates 14 are used to fix the top plate 12 on the bottom plate 11, and the strength of the entire basic installation component 1 is strengthened through the rib plates 14. The support block 13 is fixed on the top plate 12, and the support block 13 is located between the two rib plates 14. The two rib plates 14 are on both sides of the top plate 12, and the support block 13 is in the middle of the top plate 12.

[0030] As Figure 2 and Figure 3 , in order to ensure that the test head 3 can always be in contact with the pull rod 6 to be tested, so as to accurately measure the angle, an elastic force component for applying a force to the test head 3 in the direction of the pull rod 6 to be tested is provided on the support block 13.

[0031] The elastic force component includes an adjusting nut 71, a pressing block 72, an adjusting bolt 73 and a spring 74. The adjusting bolt 73 passes through the support block 13. The adjusting nut 71 is sleeved on one end of the adjusting bolt 73. The other end of the adjusting bolt 73 is connected to the pressing block 72, and the pressing block 72 is in contact with the test head 3. The spring 74 is located in the middle of the adjusting bolt 73. The support block 13 is provided with a spring 74 groove. One end of the spring 74 is in contact with the spring 74 groove, and the other end of the spring 74 is in contact with one end of the adjusting bolt 73 close to the pressing block 72. The pressing block 72 is abutted against the back of the test head 3 by the elastic force of the spring 74 to ensure that the test head 3 is in close contact with the pull rod 6 to be tested.

[0032] Since the test head 3 will have a rotation angle, if the pressing block 72 cannot rotate, it cannot be ensured that the pressing block 72 is in close contact with the test head 3. Therefore, the pressing block 72 and the adjusting bolt 73 are connected by a pin 75, and the pin 75 is arranged parallel to the pull rod 6 to be tested. The pressing block 72 is a U-shaped pressing block, and the two side ends of the U-shaped pressing block are in contact with the test head 3, so that it can better ensure that the U-shaped pressing block is in contact with the back of the test head 3.

[0033] As Figure 2 and Figure 3 , the angle sensing component 2 includes an angle sensor and a coupling. The angle sensor is fixed on the support block 13. One end of the angle sensor is connected to an external display component, and the other end of the angle sensor is connected to the test head 3 through the coupling. When the test head 3 is pushed to rotate an angle, the coupling will also make the angle sensor rotate by the same angle, and the angle sensor will display the rotation angle through the display screen to complete the test.

[0034] With the above technical solutions, in the efficient pull rod angle detection device, there are at least two groups of positioning components 4. The positioning component 4 includes a positioning V-block 41, a rotary clamping cylinder 42 and a cylinder push rod 43. The pull rod 6 to be tested is located in the V-groove of the positioning V-block 41. The rotary clamping cylinder 42 is connected to the cylinder push rod 43, and the cylinder push rod 43 fixes the pull rod 6 to be tested in the V-groove.

[0035] With the above technical solutions, one surface of the upper part of the pull rod to be tested in the present invention is closely attached to the test head. The test head is pushed to rotate an angle, and the coupling makes the angle sensor rotate by the same angle. The angle sensor outputs a signal to the amplifier display, and the amplifier display shows the rotation angle. The two front sides of the U-shaped pressing block always abut against the back surface of the test head, so that the front surface of the test head can be closely attached to one surface of the pull rod to be tested, thereby ensuring reliable and accurate measurement of the angle.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
