Description

Technical Field

[0001] This utility model relates to the field of cylinder stroke detection technology, specifically a cylinder stroke accuracy detection mechanism. Background Technology

[0002] In industrial automation, cylinders are the core actuators that realize linear reciprocating motion. Their stroke accuracy directly affects the coordination of equipment movements and operational reliability. Therefore, efficient and accurate detection of cylinder stroke accuracy has become a key link in ensuring the quality of industrial products.

[0003] In existing automated testing platforms, the cylinder positioning mechanism is fundamental to ensuring testing accuracy. Its function is to fix the cylinder under test in a preset reference position, ensuring that the cylinder's motion axis is consistent with the detection direction of the displacement sensor, and avoiding measurement deviations caused by installation tilt or offset. However, the current mainstream positioning mechanisms have significant limitations in height adjustment: most mechanisms adopt a fixed or bolt-locked stepped height adjustment structure, such as setting screw holes of different heights on the base and changing the fixed position of the cylinder mounting plate to achieve height adjustment, which is relatively cumbersome. Therefore, we need to propose a cylinder stroke accuracy testing mechanism. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A cylinder stroke accuracy testing mechanism includes: a worktable 1, with a sliding testing mechanism 2 fixedly connected to its top, and the telescopic end of the cylinder to be tested connected to the sliding testing mechanism 2; a positioning shell 3 fixedly embedded in the top of the worktable 1, with a lifting plate 4 on the top of the positioning shell 3, the cylinder to be tested mounted on the top of the lifting plate 4, and an adjustment component 5 for coarsely adjusting the height of the lifting plate 4 on the positioning shell 3; two sets of level rulers 6 fixedly connected to the side walls of the lifting plate 4, with the two sets of level rulers 6 respectively on the X-axis and Y-axis of the lifting plate 4; and four sets of leveling components 7 symmetrically arranged on the lifting plate 4 to ensure its levelness. By combining the worktable 1, sliding testing mechanism 2, positioning shell 3, lifting plate 4, adjustment component 5, level rulers 6, and leveling components 7, the mechanism achieves the effect of ensuring the orderly conduct of cylinder stroke accuracy testing from installation and positioning to testing operation.

[0025] The adjustment assembly 5 includes a first threaded sleeve 501, which is fixedly embedded in the top of the positioning housing 3. A first screw 502 is threadedly connected to the inside of the first threaded sleeve 501. The top end of the first screw 502 is rotatably connected to the bottom of the lifting plate 4, and a handwheel 503 is fixedly connected to the bottom end of the first screw 502. By setting up the adjustment assembly 5, which consists of the first threaded sleeve 501, the first screw 502, and the handwheel 503, the height of the lifting plate 4 can be quickly and coarsely adjusted, shortening the preparation time before testing.

[0026] It also includes four sets of linear bearings 504, which are symmetrically and fixedly embedded in the top of the positioning housing 3. Guide rods 505 are slidably inserted into the interior of each linear bearing 504, and the top of the guide rods 505 is fixedly connected to the bottom of the lifting plate 4. By setting four sets of symmetrical linear bearings 504 and guide rods 505, the lifting plate 4 is guided during lifting, avoiding deviation during lifting and improving the stability and accuracy of height adjustment.

[0027] The leveling component 7 includes a second threaded sleeve 701, which is fixedly embedded inside the lifting plate 4. A second screw 702 is threadedly connected to the inside of the second threaded sleeve 701. A stop block 703 is fixedly connected to the bottom end of the second screw 702, and the bottom of the stop block 703 abuts against the top of the positioning shell 3. A knob 704 is fixedly connected to the top end of the second screw 702. By setting up the leveling component 7, which consists of the second threaded sleeve 701, the second screw 702, the stop block 703, and the knob 704, in conjunction with the spirit level 6, the levelness of the lifting plate 4 is precisely adjusted, ensuring that the cylinder under test is in a horizontal state and reducing testing errors caused by cylinder tilt.

[0028] The sliding detection mechanism 2 includes a slide rail 201, which is fixedly connected to the top of the worktable 1. A slider 202 is slidably connected to the slide rail 201, and a grating ruler 203 is fixedly connected to the top of the slide rail 201. A reading head corresponding to the grating ruler 203 is fixedly connected to the inner top of the slider 202. By setting up the sliding detection mechanism 2, which consists of the slide rail 201, slider 202, grating ruler 203, and reading head, the mechanism achieves stable following and accurate acquisition of stroke data during cylinder extension and retraction, providing a reliable data source for stroke accuracy detection.

[0029] It also includes a perforated mounting plate 204 that connects to the telescopic end of the cylinder to be tested. The perforated mounting plate 204 is fixedly connected to the top of the slider 202. By setting the perforated mounting plate 204, it is possible to adapt to the telescopic end connection of cylinders of different models and sizes, thereby improving the versatility and ease of connection of the mechanism.

[0030] The telescopic end of the cylinder under test is bolted to the corresponding hole on the multi-hole mounting plate 204 via a standard component. By setting the bolting method between the standard component and the corresponding hole on the multi-hole mounting plate 204, the connection between the telescopic end of the cylinder under test and the multi-hole mounting plate 204 is ensured to be stable, the concentricity after connection is guaranteed, and the impact of connection gap on testing accuracy is reduced.

[0031] It is worth noting that the laser collimator ensures that the axis of the cylinder under test is parallel to the direction of the sliding detection mechanism. The laser emission direction of the laser collimator is parallel to the guiding direction of the sliding detection mechanism 2. The cylinder body of the cylinder under test is equipped with a laser receiving target that cooperates with the laser collimator. The laser receiving target can display the position of the laser spot. By setting up the laser collimator and the laser receiving target, the parallelism between the axis of the cylinder under test and the direction of the sliding detection mechanism 2 can be directly monitored.

[0032] Working principle: First, the cylinder to be tested is installed on the lifting plate 4. Then, the handwheel 503 of the adjusting component 5 is rotated. With the cooperation of the first screw sleeve 501 and the first screw 502, the lifting plate 4 is driven to rise and fall along the guide rod 505 inside the linear bearing 504, achieving coarse height adjustment so that the cylinder is approximately at a suitable testing height. Subsequently, according to the display of the level ruler 6 on the X and Y axes, the knob 704 of the leveling component 7 is rotated. Through the action of the second screw sleeve 701 and the second screw 702, the abutment block 703 is moved up and down, adjusting the lifting plate 4 to a horizontal state. Afterward, the cylinder extension end is bolted and fixed to the multi-hole mounting plate 204 using standard parts. The cylinder to be tested is started, and its extension end drives the multi-hole mounting plate 204 and the slider 202 to slide along the slide rail 201. At this time, the grating ruler 203 cooperates with the reading head to collect the displacement data of the slider 202 in real time. This data reflects the stroke change of the cylinder to be tested, thereby completing the detection of the cylinder stroke accuracy.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
