Description

Technical Field

[0001] This utility model relates to the field of industrial machinery gauge technology, specifically a corrosion-resistant industrial machinery gauge. Background Technology

[0002] In industrial machinery, gauges have a simple structure and are usually solid objects with accurate dimensions and shapes. This type of gauge is a thread plug gauge, which is used to comprehensively inspect the threads in industrial machinery parts. It simulates the maximum material profile of the thread being tested and checks whether the effective pitch diameter of the thread being tested exceeds the pitch diameter of its maximum material profile. At the same time, it checks whether the actual size of the root diameter exceeds its maximum material size.

[0003] A search revealed a Chinese patent publication number: CN222528474U, which provides a body comprising: a main body including a first connecting rod, a second connecting rod mounted on the surface of the first connecting rod, and an mounting block mounted on the surfaces of the first and second connecting rods, wherein a plug gauge go end and a plug gauge stop end are fixedly connected to the surface of the mounting block; and a splitting mechanism including an installation chamber.

[0004] Although the aforementioned patent allows for the disassembly and assembly of the plug gauge's go end and stop end, the aforementioned plug gauge go end still has the following problems: During the use of existing gauges, the exposed threads at both ends can easily scratch the operator's hands or the workpiece surface when rotating or contacting the workpiece. When the gauge is not in use or is stored, the exposed threads are prone to accumulating dust, oil stains, or colliding with other objects, leading to thread wear and corrosion, which affects measurement accuracy. In view of the above situation, technical innovation is carried out on the basis of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant industrial machinery gauge to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant industrial mechanical gauge, comprising a connecting rod, with fixed blocks fixedly connected to both the upper and lower ends of the connecting rod, and rotating rods rotatably connected to one side of each of the two fixed blocks. A plug gauge go end and a plug gauge stop end are respectively fixedly installed on the side of the two rotating rods away from the fixed blocks by bolts. Two protective frames are provided on the surface of the connecting rod, and a cover plate is rotatably connected to the top of each protective frame. An internal groove is provided on the top of each protective frame.

[0007] Preferably, the top of the protective frame has a slot, the surface of the rotating rod is fixedly connected to a plug, and the interior of the slot is slidably connected to the surface of the plug.

[0008] Preferably, the protective frame has a groove inside, and the inside of the groove is slidably connected to the surface of the slide rail.

[0009] Preferably, the protective frame has a transmission groove inside, and two racks are slidably connected inside the transmission groove.

[0010] Preferably, two springs are fixedly connected inside the transmission groove, and the side of the spring near the rack is fixedly connected to the surface of the rack.

[0011] Preferably, a gear is rotatably connected inside the transmission groove, and the gear is meshed with racks on both sides.

[0012] Preferably, the inner walls on both sides of the slide rail are provided with fixing grooves, and the two racks are respectively adapted to the two fixing grooves.

[0013] Preferably, a rotating handle is fixedly connected to one side of the gear, and one end of the rotating handle rotates through the interior of the protective frame and extends to the exterior of the protective frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This corrosion-resistant industrial machinery gauge, through the cooperation of the protective frame and handle, allows the protective frame to cover the measuring area when the gauge is not in use. When in use, only the protective frame needs to be opened for inspection, effectively reducing the risk of accidental contact with the threads. At the same time, it can effectively isolate external contaminants, keep the threads clean, and ensure the measurement accuracy and repeatability of the gauge. In addition, by replacing the materials of the plug gauge's go end and stop end with highly corrosion-resistant materials, it can effectively resist chemical and electrochemical corrosion, maintain the original dimensional stability and surface finish of the gauge, and ensure long-term measurement accuracy.

[0015] 2. This corrosion-resistant industrial mechanical gauge, through the cooperation of the rotating rod and the insert, can be rotated more stably by holding the bent protective frame. It is more suitable for deep holes, blind holes or scenarios with obstacles around them, reducing interference between the hand and the workpiece, improving the convenience of operation, and at the same time reducing direct contact between the hand and the thread of the inspection end, significantly reducing the probability of scratches and improving operational safety.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a corrosion-resistant industrial machinery gauge, including a connecting rod 1. Both the upper and lower ends of the connecting rod 1 are fixedly connected to fixing blocks 9. Rotating rods 5 are rotatably connected to one side of each fixing block 9. A plug gauge through end 4 and a plug gauge stop end 18 are respectively fixedly installed on the side of the two rotating rods 5 away from the fixing blocks 9 by bolts. The plug gauge through end 4 can be disassembled and replaced by bolts. Simultaneously, the plug gauge through end 4 can be fully screwed into the internal thread of the part, indicating that the part is qualified. Both the plug gauge through end 4 and the plug gauge stop end 18 are made of selected corrosion-resistant materials, effectively resisting chemical and electrochemical corrosion. Two protective frames 2 are provided on the surface of the connecting rod 1. A cover plate 3 is rotatably connected to the top of the protective frame 2. The cover plate 3 is fixedly installed on the top of the protective frame 2 by a snap fastener. The cover plate 3 can also be fixed by the snap fastener when rotated to the surface of the protective frame 2. Since the snap fastener is existing technology, it will not be elaborated further here. An internal groove 10 is provided on the top of the protective frame 2.

[0020] The top of the protective frame 2 has a slot 11, and the surface of the rotating rod 5 is fixedly connected to the insert 6. The inside of the slot 11 is slidably connected to the surface of the insert 6. By sliding the insert 6 into the inside of the slot 11, the rotating rod 5 is fixed.

[0021] The protective frame 2 has a sliding groove 12 inside, and the inside of the sliding groove 12 is slidably connected to the surface of the slide rail 7. By sliding the slide rail 7 inside the sliding groove 12, the protective frame 2 can slide while being limited.

[0022] The protective frame 2 has a transmission groove 13 inside, with two racks 15 slidably connected inside the transmission groove 13. Two springs 14 are fixedly connected inside the transmission groove 13, with the side of the spring 14 near the rack 15 fixedly connected to the surface of the rack 15. By sliding the rack 15, the spring 14 is compressed and reset. A gear 16 is rotatably connected inside the transmission groove 13, and the gear 16 meshes with the racks 15 on both sides. By rotating the gear 16, the racks 15 are driven to slide inside the transmission groove 13. Fixed grooves 17 are opened on the inner walls of both sides of the slide rail 7. The two racks 15 are respectively matched with the two fixed grooves 17. The protective frame 2 is fixed by sliding the racks 15 into the fixed grooves 17. A rotating handle 8 is fixedly connected to one side of the gear 16. One end of the rotating handle 8 rotates through the inside of the protective frame 2 and extends to the outside of the protective frame 2. By rotating the rotating handle 8, the gear 16 drives the two racks 15 to slide relative to each other and compress or reset the springs 14, causing the racks 15 to slide out or into the fixed grooves 17.

[0023] Working principle: For this type of corrosion-resistant industrial mechanical gauge, when the plug gauge end 4 is needed to inspect parts, the top rotating handle 8 is rotated to bring the two racks 15 closer together. When the two racks 15 are close to each other, they compress the spring 14 and cause the racks 15 to slide out of the fixing groove 17, releasing the fixation to the slide rail 7. Then, the top protective frame 2 slides downward under the limit of the slide rail 7. After sliding to a certain position, the rotating rod 5 is rotated to bend at a 90-degree angle and then moves upward. Slide the protective frame 2 to allow the insert 6 to slide into the slot 11 for fixation. Then, by releasing the rotating handle 8, the spring force of the spring 14 can drive the two racks 15 away from each other and slide them back into the fixing groove 17, thus completing the fixation of the protective frame 2. By testing the plug gauge end 4 at a 90-degree bending angle, it is easier to screw the connecting rod 1 into the internal thread of the part for testing. At the same time, both the plug gauge end 4 and the plug gauge stop end 18 are made of corrosion-resistant materials, which can effectively resist chemical and electrochemical corrosion.

[0024] When the test is completed and re-fixing is required, slide the rack 15 out of the fixing groove 17, then slide the protective frame 2 downward to make the insert 6 slide out of the slot 11, then rotate the plug gauge end 4 to keep it vertical, then slide the protective frame 2 upward to make it slide into the inner groove 10 to fix the plug gauge end 4 and prevent it from moving around due to shaking. Then, use the buckle to cover the top of the protective frame 2 to fix it and protect it.

[0025] 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.
