Description

Technical Field

[0001] This utility model relates to the field of mechanical tolerance testing technology, and more specifically, it relates to a mechanical stroke testing device. Background Technology

[0002] The mechanical stroke of a contact angle sensor refers to the total rotation angle of the rudder shaft of a stop-type contact angle sensor from the start point to the end point of the stop.

[0003] The principle is to fix a contact angle sensor on the testing device, drive the rudder shaft of the contact angle sensor to move it from the starting point to the ending point, and use a photoelectric encoder to measure the rotation angle. The total angle from the starting point to the ending point is the mechanical stroke.

[0004] Existing contact angle sensor mechanical travel testing equipment fixes the product on a limit fixture, connects the photoelectric encoder to the test shaft via a coupling, inserts the test shaft into the contact angle sensor's rudder shaft, moves the rudder piece on the contact angle sensor's rudder shaft to the endpoint in a certain direction, presses the zero button on the photoelectric encoder display, and then moves the rudder piece to the endpoint in another direction. The value displayed by the photoelectric encoder is the mechanical travel test value of the contact angle sensor under test.

[0005] The current testing method involves mounting a contact angle sensor on a hand-cranked indexing table. The installation process is complex, and the testing process requires cranking the indexing table to control the rudder shaft of the contact angle sensor to rotate from the starting point to the ending point. Due to the limitations of the mechanical structure of the mounting table, the testing efficiency is extremely low. Utility Model Content

[0015] The cylindrical structure of the mounting cylinder allows for installation in various situations, and its concentricity can be checked during installation to ensure the concentricity of the bearing mounting seat and the channel inside the mounting cylinder, thus facilitating better testing.

[0016] The present invention is further characterized by having a reserved mounting hole on the mounting plate.

[0017] The pre-drilled mounting holes facilitate the embedding and installation of the bearing mounting base, which has a clearance fit with the sensor rudder shaft.

[0018] The present invention is further configured such that: the outer periphery of the mounting cylinder is provided with a hollow hole that completely penetrates into the channel inside it.

[0019] The perforated design makes the installation and disassembly of the coupling more convenient, and allows for repeated and complex installation of the rudder shaft.

[0020] The present invention is further configured such that: the outer shell on one side of the output shaft of the photoelectric encoder is fixedly connected to the mounting cylinder, and the output shaft of the photoelectric encoder is at least partially inserted into the axial channel of the mounting cylinder.

[0021] The output shaft of the photoelectric encoder can only be directly exposed at the cutout hole position when it is partially inserted into the mounting cylinder, so as to facilitate the assembly and disassembly of the coupling.

[0022] The present invention is further configured such that a bearing mounting seat is embedded in the reserved mounting hole.

[0023] The bearing mounting base facilitates the stabilization of the radial rotation accuracy of the rudder shaft.

[0024] In summary, this utility model has the following beneficial effects: the display and testing device are supported by the frame to achieve collaborative work without excessive workload; the bearing mounting seat ensures the accuracy of radial rotation of the test shaft; the mounting cylinder can ensure a certain degree of concentricity while installing the photoelectric encoder; and the display of the photoelectric encoder can more conveniently read the test values.

[0037] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0038] Example

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a mechanical stroke testing device includes a frame 1, a display 3, and a testing device 2.

[0040] The rack 1 is used to support the test device 2 and the display 3.

[0041] The frame 1 includes a base plate 11. A display 3 is installed on one side of the top surface of the base plate 11 near the edge. Several rectangularly arranged support rods 12 are installed on the other side of the top surface of the base plate 11. A mounting plate 13 is installed at the end of the support rods 12 away from the base plate 11 to suspend the testing device 2. The suspended mounting plate 13 can raise the photoelectric encoder 24, thereby facilitating maintenance, installation, and replacement.

[0042] The display 3 is used to display the rotation angle and test status, and the display 3 is fixedly installed on one side of the frame 1;

[0043] The testing device 2 is mounted on the frame 1 and adjacent to the display 3. The testing device 2 includes a mounting cylinder 21 connected to the frame 1, a bearing mounting seat 22 embedded in the frame 1, a limiting block 23 mounted on the frame 1, and a photoelectric encoder 24 mounted on the end of the mounting cylinder 21 away from the frame 1. The frame 1 is also provided with a limiting block 23 for mounting the workpiece. The limiting block 23 is provided with a limiting groove 231 for accommodating the workpiece on the side away from the frame 1. The limiting groove 231 is provided with a through hole 232 for the workpiece to pass through. A coupling 25 is provided on the output end of the photoelectric encoder 24.

[0044] The coupling 25 eliminates the concentricity error between the photoelectric encoder 24 and the contact angle sensor rudder shaft, reducing their respective rotational torque.

[0045] The mounting cylinder 21 is a cylindrical structure with an internal cylindrical channel. It is axially and vertically mounted on the bottom surface of the mounting plate 13. Both ends of the mounting cylinder 21 have flanges 211 extending away from the axis. The cylindrical structure of the mounting cylinder 21 allows for installation in various configurations, and its concentricity can be simultaneously checked during installation to ensure the concentricity of the bearing mounting seat 22 and the internal channel of the mounting cylinder 21, facilitating better testing.

[0046] The mounting plate 13 is provided with a reserved mounting hole 131. The reserved mounting hole makes it easier for the bearing mounting seat 22 to be inserted and installed. The bearing mounting seat 22 and the sensor rudder shaft are clearance fit.

[0047] The mounting cylinder 21 has a perforated hole 212 on its outer periphery that extends completely into its internal channel. The perforated hole 212 makes it easier to install and remove the coupling 25, allowing for repeated and complex installation of the rudder shaft.

[0048] The outer casing on one side of the output shaft of the photoelectric encoder 24 is fixedly connected to the mounting sleeve 21, and the output shaft of the photoelectric encoder 24 is at least partially inserted into the axial channel of the mounting sleeve 21. Only when the output shaft of the photoelectric encoder 24 is partially inserted into the mounting sleeve 21 can the installation position be directly exposed at the position of the cutout hole 212, so as to facilitate the assembly and disassembly of the coupling 25.

[0049] A bearing mounting seat 22 is embedded in the reserved mounting hole 131. The bearing mounting seat 22 facilitates the stabilization of the radial rotation accuracy of the rudder shaft.

[0050] In this embodiment, the photoelectric encoder 24 is signal-connected to the display 3. The photoelectric encoder 24 and the display 3 can be powered by a power source, a bus, or a storage power source, respectively.

[0051] In this embodiment, a mounting frame for the display 3 is also included, as shown in the figure. Figure 3 As shown, it has an opening at the top that allows the monitor 3 to be installed at an angle, ensuring ergonomic design and ease of operation.

[0052] Beneficial effects: The frame 1 can support the display 3 and the test device 2 together to achieve the effect of collaborative work without too much work. The bearing mounting seat 22 ensures the accuracy of the test shaft in radial rotation. The mounting cylinder 21 can ensure a certain degree of concentricity while installing the photoelectric encoder 24. The display 3 of the photoelectric encoder 24 can read the test value more conveniently.

[0053] Working principle: Based on the model of the contact angle sensor being tested, select the appropriate test shaft and limit block 23 and install them on the coupling 25 and mounting plate 13 respectively.

[0054] The contact angle sensor to be tested is installed on the test shaft and the limit block 23.

[0055] First, rotate the rudder shaft of the contact angle sensor under test to any stop point (as the starting point). Then, reset the value on the output value display of the photoelectric encoder 24 to zero. Next, rotate the rudder shaft of the contact angle sensor under test to another stop point (as the end point). At this time, the number on the output value display of the photoelectric encoder 24 is the mechanical travel of the contact angle sensor under test.

[0056] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0057] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
