Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder detection, and specifically relates to an oil cylinder pressing detection mechanism. Background Art

[0002] During the use of an oil cylinder, generally, a driving pressure plate is used to press and position a workpiece. With the increasing need for automated scenarios, there are new challenges for the oil cylinder, and it is required that the pressing and releasing of the oil cylinder can achieve a position confirmation function. Usually, the oil cylinder needs to be detected. Currently, the most commonly used detection method in the field of oil cylinders is airtight detection.

[0003] In the prior art, the commonly used detection method for an oil cylinder is airtight detection. However, airtight detection is an internal detection that measures the position of the oil cylinder piston and cannot directly detect the true position of the pressure plate. When the oil cylinder fails, incorrect detection information may occur. Therefore, an oil cylinder pressing detection mechanism is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an oil cylinder pressing detection mechanism to solve the problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An oil cylinder pressing detection mechanism includes a bottom plate. On the left side of the top outer surface of the bottom plate, an oil cylinder body is fixedly installed. At the output end of the oil cylinder body, there is a pressure plate. On the front outer surface of the left side of the top outer surface of the bottom plate, there is a first sheet metal part, and a first proximity switch is installed on the outer surface of the first sheet metal part. At the center of the rear end of the top outer surface of the bottom plate, there is a second sheet metal part, and a second proximity switch is installed on the outer surface of the second sheet metal part.

[0006] Further, four positioning holes arranged in a circular array are opened on the bottom outer surface of the bottom plate on the right side of the oil cylinder body. Circular pins are arranged inside the four positioning holes, and a workpiece is arranged at the center of the four circular pins.

[0007] Further, both the first sheet metal part and the second sheet metal part are L-shaped parts. At one end of the vertical surface of the first sheet metal part and the second sheet metal part, accommodation grooves are opened, and the first proximity switch and the second proximity switch are respectively arranged inside the two accommodation grooves.

[0008] Further, at one end of the bottom horizontal plane of both the first sheet metal part and the second sheet metal part, installation holes are opened.

[0009] Further, the position of the horizontal plane of the first proximity switch is higher than the position of the horizontal plane of the second proximity switch.

[0010] Further, the detection end of the first proximity switch faces the right end, and the detection end of the second proximity switch faces the front end.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For this oil cylinder pressing detection mechanism, by setting the first proximity switch and the second proximity switch to respectively detect the positions of the pressing plate in the two states of loosening and pressing the workpiece, the position of the pressing plate can be detected more directly, avoiding incorrect detection positions, and thus achieving a true detection result.

[0013] 2. For this oil cylinder pressing detection mechanism, by using a common oil cylinder for detection, the use of airtight oil cylinders is reduced, and the use cost is lowered. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1:

[0021] Please refer to Figures 1 - 4, the present utility model provides a technical solution: an oil cylinder pressing detection mechanism, including a bottom plate 1. On the outer surface of the top of the bottom plate 1, an oil cylinder body 2 is fixedly installed on the left side. At the output end of the oil cylinder body 2, there is a pressing plate 3. On the outer surface of the top of the bottom plate 1, on the left side and near the front end, there is a first sheet metal part 4. On the outer surface of the first sheet metal part 4, a first proximity switch 5 is installed. At the center of the outer surface of the top of the bottom plate 1 and near the rear end, there is a second sheet metal part 6. On the outer surface of the second sheet metal part 6, a second proximity switch 7 is installed. In this embodiment, when pressing, the pressing plate 3 rotates 90° and presses against the top of the workpiece 10. At this time, the second proximity switch 7 detects the position of the pressing plate 3 and feeds back a signal, and the first proximity switch 5 does not detect a signal. When the pressing plate 3 is in the relaxed state, the oil cylinder pressing plate 3 rotates 90° and moves away from the workpiece 10. The first proximity switch 5 detects the position of the pressing plate 3 and feeds back a signal, and the second proximity switch 7 does not detect a signal.

[0022] On the outer surface of the bottom of the bottom plate 1, on the right side of the oil cylinder body 2, four positioning holes 8 are provided in a circular array. Inside each of the four positioning holes 8, there is a round pin 9. At the center of the four round pins 9, there is a workpiece 10. In this embodiment, the round pin 9 is inserted into the positioning hole 8, and the workpiece 10 is arranged at the center of the round pin 9. The workpiece 10 is limited by the round pin 9.

[0023] Both the first sheet metal part 4 and the second sheet metal part 6 are L-shaped parts. At one end of the vertical surface of the first sheet metal part 4 and the second sheet metal part 6, a receiving groove is provided. The first proximity switch 5 and the second proximity switch 7 are respectively arranged inside the two receiving grooves. In this embodiment, the receiving grooves are provided to provide space for the installation of the first proximity switch 5 and the second proximity switch 7.

[0024] At one end of the bottom horizontal plane of the first sheet metal part 4 and the second sheet metal part 6, a mounting hole is provided. In this embodiment, the first sheet metal part 4 and the second sheet metal part 6 are installed on the bottom plate 1 through the mounting holes.

[0025] The position of the horizontal plane of the first proximity switch 5 is higher than the position of the horizontal plane of the second proximity switch 7. In this embodiment, adopting the above technical solution, when the pressing plate 3 is relaxed, the pressing plate 3 will move upward, so that the first proximity switch 5 can correspond to the pressing plate 3. When the pressing plate 3 is pressed, the pressing plate 3 will move downward, so that the second proximity switch 7 can correspond to the pressing plate 3.

[0026] The detection end of the first proximity switch 5 faces the right end, and the detection end of the second proximity switch 7 faces the front end. In this embodiment, adopting the above technical solution, when the pressing plate 3 rotates 90 degrees when loose, the first proximity switch 5 facing the right end can correspond to the pressing plate 3 to detect the position of the pressing plate 3. When the pressing plate 3 rotates 90 degrees to be in the pressed state, the second proximity switch 7 facing the front end can correspond to the pressing plate 3 to detect the position of the pressing plate 3 at this time.

[0027] Working principle: When in use of the present utility model, when it is necessary to detect the position of the pressing plate 3 of the oil cylinder body 2, first fix the workpiece 10. When fixing, insert the round pin 9 into the positioning hole 8 to limit the periphery of the workpiece 10, so that the pressing plate 3 presses the workpiece 10. When pressing, the pressing plate 3 rotates 90° and presses against the top of the workpiece 10. At this time, the second proximity switch 7 detects the position of the pressing plate 3 and feeds back a signal, and the first proximity switch 5 does not detect a signal. In the relaxed state of the pressing plate 3, the oil cylinder pressing plate 3 rotates 90° and moves away from the workpiece 10. The first proximity switch 5 detects the position of the pressing plate 3 and feeds back a signal, and the second proximity switch 7 does not detect a signal. Thus, the detection of the position of the pressing plate 3 of the oil cylinder body 2 is completed. Therefore, by using an ordinary oil cylinder, the pressing plate 3 is directly detected to detect the two positions of the pressing and relaxation of the pressing plate 3, which can avoid incorrect detection positions and thus achieve a true detection result.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
