Description

Technical Field

[0001] The utility model relates to the field of shim installation, and particularly relates to a shim selection device. Background Art

[0002] Our company has developed a clutch actuator, with the patent number CN220204636U. As shown in the attached drawings of the specification, Figure 1 the clutch actuator includes a front shell and a rear shell. An installation cavity is provided inside the front shell, the opening of the installation cavity faces upward, and a worm and worm gear structure is provided inside the installation cavity;

[0003] The last step of the installation is as follows: the transmission shaft passes through the sector worm wheel and is key-connected to the sector worm wheel. Then, the sector worm wheel (a part inside the shell) is installed into the installation cavity. A bearing sleeve is installed on the transmission shaft. The transmission shaft has a partial protrusion relative to the upper surface of the bearing sleeve. A gasket is placed on the bearing sleeve. The rear shell and the front shell are assembled together so that the gasket is located between the rear shell and the bearing sleeve to fix the bearing sleeve. The transmission shaft passes through the rear shell for power connection with other structures (gearbox).

[0004] However, during the actual installation of the bearing sleeve, there are often certain errors in the height of the upper surface of the bearing sleeve. In order to better compensate for this error, it is more appropriate to select gaskets with different thicknesses according to the actual error value. Since the upper surfaces of the front shell and the rear shell are in direct contact, the upper surface of the front shell is usually used as the reference surface. Usually, the height difference between the upper surface of the front shell and the upper surface of the bearing sleeve is calculated to determine the error value, so as to determine the thickness of the selected gasket.

[0005] However, to ensure the installation and normal operation of the sector turbine, there is a distance left in the horizontal direction between the installation front side walls of the bearing sleeve and the front shell, which is not convenient for directly measuring with a measuring tool. Otherwise, the error is relatively large. Therefore, a shim selection device is needed to facilitate measuring the height difference between the upper surface of the front shell and the upper surface of the bearing sleeve (a part inside the shell). Summary of the Utility Model

[0006] The utility model aims to provide a shim selection device that is convenient for measuring the height difference between the upper surface of the front shell and the upper surface of the part inside the shell.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: A shim selection device includes a guide sleeve, a support part, a first measuring head, and a measuring instrument. A support part is provided on the lower side of the guide sleeve. The lower surface of the support part is a plane, and the lower surface of the support part is used to support on the upper surface of the front shell. The first measuring head is vertically slidably arranged inside the guide sleeve, and the lower surface of the first measuring head is used to support on the upper surface of the part inside the shell. The measuring instrument is used to measure the height difference between the upper surface of the guide sleeve of the front shell and the upper surface of the first measuring head.

[0008] The beneficial effects of this scheme are as follows:

[0009] 1. Support the lower surface of the support part on the upper surface of the front shell, and transfer the height of the upper surface of the front shell to the support part and the guide sleeve; support the lower surface of the first probe on the upper surface of the part inside the shell, and transfer the height of the upper surface of the part inside the shell to the first probe; then, by measuring the height difference between the guide sleeve and the first probe, the height difference between the upper surface of the front shell and the upper surface of the part inside the shell can be reflected.

[0010] 2. Compared with directly measuring the height difference between the upper surface of the front shell and the upper surface of the part inside the shell, in this solution, the guide sleeve and the first probe are in sliding fit, with a short distance, which is convenient for measurement, and thus it is convenient to measure the height difference between the upper surface of the front shell and the upper surface of the part inside the shell.

[0011] 3. When the front shell is placed horizontally, the upper surface of the front shell serves as a reference surface with high precision. Therefore, supporting the lower surface of the support part on the upper surface of the front shell can ensure that the lower surface of the support part is also horizontal, thereby ensuring that the guide cylinder is vertically arranged, and further ensuring that the first probe can smoothly fall on the upper surface of the part inside the shell under the action of gravity. If the sector worm gear is not installed firmly at this time, the pressure of the gravity of the first probe on the sector worm gear can press the sector worm gear into a stable and correct position, ensuring that the position of the sector turbine is consistent with the position after installing the mounting gasket and the rear shell.

[0012] 4. This solution is not only applicable to the clutch actuator, but also applicable to all situations where high precision is required, there is a part inside the front shell, there is a distance between the side wall of the installation cavity of the part inside the shell and the front shell, and it is not convenient to directly measure the height difference between the upper surface of the front shell and the upper surface of the part inside the shell.

[0013] Furthermore, a first receiving groove is provided on the lower surface of the first probe, and the first receiving groove is used to receive the local protrusion on the upper surface of the part inside the shell.

[0014] Furthermore, the guide sleeve and the support part are detachably connected.

[0015] Furthermore, the measuring instrument is a micrometer.

[0016] Furthermore, a threaded hole is vertically provided in the middle of the upper surface of the first probe, and an anti - detachment bolt is threadedly connected in the threaded hole, and the upper end of the anti - detachment bolt protrudes relative to the upper surface of the first probe.

[0017] Furthermore, the measuring instrument includes a second probe, and a second receiving groove is provided on the lower surface of the second probe, and the second receiving groove is used to receive the anti - detachment bolt on the upper surface of the first probe.

[0018] This solution also has the following effects:

[0019] 1. In order to facilitate regular inspection of the accuracy of the first probe, it needs to be frequently taken off for inspection. Therefore, no limiting device is provided between the guide sleeve and the first probe, and the first probe can slide out of the guide sleeve;

[0020] In actual use, for the convenience of single-handed picking and to prevent the first probe from slipping out of the guide sleeve, an anti-slip bolt is provided on the upper surface of the first probe in this solution. When the operator picks up the guide sleeve with one hand, he only needs to use the index finger above to pull the anti-slip bolt to make the first probe tend to tilt, so that the first probe is pressed tightly against the inner side of the guide sleeve, thereby preventing the first probe from slipping out of the guide sleeve. After placing the support part below the guide sleeve on the front housing, the finger can release the first probe, allowing the first probe to fall and contact the upper surface of the parts inside the housing, so as to facilitate the measurement of the height difference.

[0021] 2. Compared with setting the anti-slip bolt, if a limiting structure is directly set on the first probe or the guide sleeve to prevent the first probe from slipping out of the guide sleeve, during continuous use, the first probe constantly collides with the limiting structure, and the sliding between the first probe and the guide sleeve is no longer perpendicular and smooth, thus affecting the accuracy of the measurement result.

[0022] The anti-slip bolt moves up and down relative to the upper surface of the first probe by rotation, so as to be applicable to the height differences between different front housings and the parts inside the housing, increasing the scope of application.

[0023] 3. The guide sleeve and the support part are detachably connected, so as to facilitate the replacement of different support parts and be applicable to different housings. Description of the Drawings
