[0024] The utility model embodiment is explained in detail below in combination with the drawings.

[0025] As Figs. 1-3 Indicated, a kind of cam divider detection device, including bearing platform 1, bearing platform 1 is equipped with the conversion mechanism 2 of connecting cam divider 4, for conversion cam divider 4 each division equal parts gap;Bearing platform (1) is equipped with still with conversion mechanism 2 cooperation for the measuring mechanism 3 of reaction gap width, conversion mechanism 2 includes pin wheel 201 and the clamp 202 clamped on pin wheel 201.

[0026] Further, the cam divider 4 is arranged on the bearing platform 1, and the conversion mechanism 2 is connected to the output shaft 401 of the cam divider 4. Specifically, the cam divider 4 is provided with the output shaft 401, the pin wheel 201 is connected to the output shaft 401, and the pin wheel 201 is coaxially arranged with the output shaft 401. The output shaft 401 serves as the output end of the cam divider 4. The connecting hole 2011 for connecting the output shaft 401 is arranged on the pin wheel 201. The output shaft 401 is connected in the connecting hole 2011. The pin wheel 201 and the output shaft 401 can synchronously rotate. The clamp 202 is clamped on the contour of the pin wheel 201. When the pin wheel 201 rotates, the clamp 202 is driven to synchronously rotate. The conversion mechanism 2 converts the performance form of each divided equal interval of the cam divider 4 into the rotation of the pin wheel 201 and the clamp 202. Therefore, the interval is more easily observed and found, the detection efficiency of the cam divider 4 is improved, and the cam divider 4 can be timely repaired.

[0027] The clamp 202 includes the clamping part 2023 matched with the contour of the pin wheel 201. The clamping part 2023 is connected with the hinged part 2022 for controlling the opening and closing of the clamping part 2023. The hinged part 2022 is provided with the handle 2021 at the end away from the clamping part 2023. Further, the clamping part 2023 is of a circular arc structure matched with the pin wheel 201. The clamping part 2023 and the handle 2021 are arranged at opposite ends of the hinged part 2022, respectively. The hinged part 2022 is connected with two symmetrically arranged handles 2021. When the handle 2021 receives an external force, the hinged part 2022 transmits the external force to the clamping part 2023. Then, by adjusting the size of the opposite force applied to the handle 2021, the clamping part 2023 can be opened and closed. The spring 2024 is arranged on the hinged part 2022. When the clamp 202 is clamped on the pin wheel 201, the clamp 202 is in a vertical state. The spring 2024 makes the clamping part 2023 in a clamping state, so that the clamp 202 will not fall off the pin wheel 201.

[0028] In the detection, first, the cam divider 4 to be detected is placed on the bearing platform 1, and the pin wheel 201 of the conversion mechanism 2 is sleeved on the output shaft 401 of the cam divider 4 to be detected, the driving shaft 402 of the cam divider 4 to be detected is manually rotated, so that the cam divider 4 to be detected is in the stationary motion cycle, at this time, the pin wheel 201 will not rotate. Then, the clamping part 2023 of the clamp 202 is clamped on the pin wheel 201, then the handle 2021 of the clamp 202 is pushed in the counterclockwise direction and the clockwise direction of the rotation of the pin wheel 201 respectively, and whether the pin wheel 201 rotates is observed. If the pin wheel 201 does not rotate, the division equal parts of the cam divider 4 to be detected do not exist gap; if the pin wheel 201 rotates, the division equal parts of the cam divider 4 to be detected exist gap, and the rotation of the pin wheel 201 will drive the clamp 202 to rotate, at this time, the performance mode of the division equal parts gap of the cam divider 4 is converted into the rotation of the clamp 202, so that the division equal parts gap is easy to be observed and found. The above operation is repeated to detect the existence of all division equal parts gaps of the cam divider 4 to be detected.

[0029] The bearing platform 1 is further provided with a measuring mechanism 3 for reacting gap width matched with the conversion mechanism 2, the measuring mechanism 3 is arranged on one side of the conversion mechanism 2, and the measuring mechanism 3 abuts against the clamp 202, and the conversion mechanism 2 is matched to realize the evaluation of the division gap width of the cam divider 4, so that the cam divider can be maintained or replaced in time, and the unstable problem of intermittent output motion caused by uneven division of the cam divider can be avoided.

[0030] Specifically, the measuring mechanism 3 is a dial gauge 301 for the reaction gap width value, and a test head 302 vertically abutting the hinge part 2022 is connected to the dial gauge 301. The test head 302 is telescopically arranged, and further, the test head 302 is connected to the dial gauge 301. The test head 302 includes a connecting part 3021 connected to the dial gauge 301, and a connecting groove along the length direction of the test head 302 is formed at the end of the connecting part 3021. A abutting part 3022 is slidingly connected in the connecting groove, and the abutting part 3022 is movable in the connecting groove. The abutting part 3022 and the connecting part 3021 are electrically connected to the dial gauge 301, and a digital display for displaying specific values is arranged on the dial gauge 301. That is, the distance moved by the abutting part 3022 can be displayed by the digital display of the dial gauge 301, and the test head 302 can measure the value. The test head 302 is horizontally arranged, and the test head 302 vertically abuts the hinge part 2022 of the clamp 202, that is, the abutting part 3022 vertically abuts the hinge part 2022.

The dial gauge 301 is connected to the second movable clamp 5021. Further, the first movable clamp 5011 can adjust the position of the horizontal support rod 502 on the vertical support rod 501, and the second movable clamp 5021 is used to clamp the dial gauge 301.

[0033] In addition, the fixed support 5 further comprises a base 503 arranged on the bearing platform 1, the vertical support rod 501 is arranged on the base 503, and the base 503 is provided with a third movable clamp 5031 for adjusting the height of the vertical support rod 501.

When the conversion mechanism 2 detects that there is a gap in the equal parts of the cam divider 4, adjust the fixed support 5 to make the telescopic test head 302 of the dial gauge 301 vertically abut on the hinge part 2022 of the clamp 202, make the telescopic test head 302 retract a certain distance, press the zero reset key, make the numerical value displayed by the digital display of the dial gauge 301 be 0, record the numerical value displayed by the digital display when the handle 2021 of the clamp 202 rotates counterclockwise and clockwise respectively, and add the absolute values of the two numerical values as the basis for evaluating the width of the gap of the equal parts of the cam divider 4. The evaluation criteria can be formulated according to different cam dividers and their uses, for example, the test head 302 of the dial gauge 301 vertically abuts on the hinge part 2022 of the clamp 302 at a distance of 70mm from the vertical surface of the needle wheel 201, when the numerical value measured by all the equal parts of the cam divider 4 is greater than 3mm, or the difference between the numerical values measured by any two equal parts is greater than 1.5mm, the cam divider needs to be replaced. As a preferred, the retracting distance of the test head 302 of the dial gauge 301 when abutting on the hinge part 2022 of the clamp 302 is greater than 3mm, so as to better evaluate the width of the gap.
