Abstract
Description
Technical Field
[0001] This utility model relates to the field of measurement technology, and in particular to a processing fixture for roller plates. Background Technology
[0002] In modern industrial production, rollers are used as key components in printing, packaging, textiles, papermaking and other fields. The processing quality of rollers directly affects the operational stability of equipment, product precision and service life. Therefore, extremely high requirements are placed on their processing precision, surface quality and production efficiency.
[0003] After traditional roller sheet processing, the inner diameter of the roller sheet hole needs to be measured. Existing measuring devices measure the inner diameter by separating two measuring claws and contacting the two sides of the hole respectively. However, when the measuring claws are separated, it is difficult to guarantee that the straight line between the two measuring claws is the diameter of the hole, resulting in inaccurate measurement. Utility Model Content
[0004] The purpose of this application is to provide a processing fixture for roller sheets to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: a processing fixture for roller sheets, including a worktable, an L-shaped support frame fixedly connected to one side of the top of the worktable, a measuring mechanism provided on the top of the L-shaped support frame, the measuring mechanism including a U-shaped side plate fixedly connected to one side of the top of the L-shaped support frame, guide rods fixedly connected between the top and bottom of both ends of the inner side of the U-shaped side plate, the same U-shaped plate being slidably fitted on the circumferential surface of the two guide rods, round holes adapted to the guide rods being opened at both ends of the top of the U-shaped plate, rectangular holes being opened on both sides of the U-shaped plate, and the rectangular holes being adapted to the U-shaped side plate, the same lead screw being rotatably connected between the top and bottom of the U-shaped side plate, and the lead screw thread passing through the top of the U-shaped plate, a lead screw nut adapted to the lead screw being fixedly fitted at the middle of the top of the U-shaped plate, a knob being fixedly connected through the top of the lead screw passing through the U-shaped side plate, and fixing plates being fixedly connected to both sides of the bottom outer wall of the U-shaped plate.
[0006] Preferably, the measuring mechanism further includes U-shaped rods that are slidably sleeved on two fixed plates. Both fixed plates have circular holes adapted to the U-shaped rods. The bottoms of the two U-shaped rods are fixedly connected to the same rectangular cover. Two positioning rods are fixedly connected between the two ends of the inner wall of the rectangular cover. The two positioning rods have the same slider slidably sleeved at both ends. The bottoms of the two sliders are fixedly connected to measuring claws. The tops of the two sliders are fixedly connected to vertical plates, and the tops of the two vertical plates slide through the rectangular cover. The top of the rectangular cover has a strip-shaped hole adapted to the vertical plate. The middle of the two vertical plates has an oblique hole, and a driving rod is slidably connected to each oblique hole. The two ends of the two driving rods are fixedly connected to adjacent fixed plates.
[0007] Preferably, the measuring mechanism further includes a pointer fixedly connected to one side of one of the sliders. A strip-shaped hole adapted to the pointer is opened on one side of the rectangular cover, and a scale line is provided on the outer wall of the rectangular cover near the pointer. Through the cooperation of the measuring mechanism and the positioning mechanism, the two measuring claws are located exactly on the same diameter of the roller plate hole. When the two measuring claws are synchronously separated and in contact with the roller plate hole, the distance between the outer ends of the two measuring claws is the diameter of the roller plate hole.
[0008] Preferably, a positioning mechanism is provided on the top of the workbench directly below the measuring mechanism. The positioning mechanism includes rectangular plates fixedly connected to both sides of the top of the workbench. A sliding rod is fixedly connected between the same end of each of the two rectangular plates. A positioning block is slidably sleeved on the same end of each of the two sliding rods. Each positioning block has a round hole at both ends that matches the sliding rod. A V-shaped groove is provided on the side of the two positioning blocks that are close to each other. The V-shaped groove ensures that the roller is centered when the positioning block is in position, thus improving stability.
[0009] Preferably, the positioning mechanism further includes a fixed rod fixedly connected to the bottom of the worktable directly below the measuring mechanism. A first rotating rod is rotatably connected to the fixed rod, and a second rotating rod is rotatably connected to both ends of the first rotating rod. A sliding block is rotatably connected to the top of each of the two second rotating rods, and each sliding block is fixedly connected to the bottom of the positioning block. Through the cooperation of the first rotating rod and the second rotating rod, the two positioning blocks move closer and further away synchronously. Sliding holes adapted to the sliding blocks are opened on both sides of the top of the worktable, and support plates are fixedly connected to both sides of the bottom of the worktable.
[0010] In summary, the technical effects and advantages of this utility model are as follows:
[0011] In this invention, the cooperation between the positioning mechanism and the measuring mechanism allows the roller plate to be positioned so that the center of the roller plate and the midpoint between the two measuring claws are on the same vertical line. As the U-shaped plate descends, the two measuring claws also descend. When the measuring claws contact the ground, the two measuring claws separate as the U-shaped plate continues to descend until the outer side of the measuring claws contacts the inner diameter of the roller plate's hole. At this point, the line connecting the outer ends of the two measuring claws is the same as the diameter of the roller plate. The inner diameter of the roller plate can then be obtained by observing the pointer and scale lines. This effectively solves the problem mentioned in the background technology that the distance between the two measuring claws is not necessarily the diameter, thus avoiding measurement errors caused by positional offsets. This makes the measurement process more stable, ensuring that the measured value strictly corresponds to the inner diameter of the roller plate, and significantly improving the reliability and accuracy of the measurement results.

[0020] Example: Reference Figure 1-5 As shown, a processing fixture for roller sheets includes a worktable 1. An L-shaped support frame 2 is fixedly connected to one side of the top of the worktable 1. A measuring mechanism 3 is provided on the top of the L-shaped support frame 2. The measuring mechanism 3 includes a U-shaped side plate 301 fixedly connected to one side of the top of the L-shaped support frame 2. Guide rods 304 are fixedly connected between the top and bottom of both ends of the inner side of the U-shaped side plate 301. The same U-shaped plate 302 is slidably sleeved on the circumferential surface of the two guide rods 304. Both ends of the top of the U-shaped plate 302 are provided with openings corresponding to the guide rods 304. The U-shaped plate 302 has a matching round hole, and rectangular holes 303 are provided on both sides of the U-shaped plate 302. The rectangular holes 303 are adapted to the U-shaped side plate 301. The top and bottom of the U-shaped side plate 301 are rotatably connected by the same lead screw 305. The lead screw 305 is threaded through the top of the U-shaped plate 302. A lead screw nut adapted to the lead screw 305 is fixedly sleeved at the middle of the top of the U-shaped plate 302. A knob is fixedly connected through the top of the lead screw 305 through the U-shaped side plate 301. Fixing plates 306 are fixedly connected to both sides of the bottom outer wall of the U-shaped plate 302.
[0021] With the above structure, the measuring mechanism 3 also includes U-shaped rods 315 that are slidably sleeved on two fixed plates 306. Both fixed plates 306 have round holes that are adapted to the U-shaped rods 315. The bottom of the two U-shaped rods 315 is fixedly connected to the same rectangular cover 307. Two positioning rods 308 are fixedly connected between the two ends of the inner wall of the rectangular cover 307. The two positioning rods 308 are slidably sleeved at both ends of the same slider 309. The bottom of the two sliders 309 is fixedly connected to the measuring claws 312. The top of the two sliders 309 is fixedly connected to the vertical plates 310, and the top of the two vertical plates 310 slides through the rectangular cover 307. The top of the rectangular cover 307 has a strip hole that is adapted to the vertical plates 310. The middle of the two vertical plates 310 has an oblique hole 311. A driving rod is slidably connected in each oblique hole 311, and the two ends of the two driving rods are fixedly connected to the adjacent fixed plates 306.
[0022] With the above structure, the measuring mechanism 3 also includes a pointer 313 fixedly connected to one side of one of the sliders 309. A strip-shaped hole adapted to the pointer 313 is opened on one side of the rectangular cover 307, and a scale line 314 is provided on the outer wall of the rectangular cover 307 near the pointer 313. Through the cooperation of the measuring mechanism 3 and the positioning mechanism 4, when the rectangular cover 307 descends, the two measuring claws 312 enter the inner side of the roller plate and automatically separate, contacting the inner diameter of the roller plate.
[0023] With the above structure: a positioning mechanism 4 is set at the top of the workbench 1 directly below the measuring mechanism 3. The positioning mechanism 4 includes rectangular plates 401 fixedly connected to both sides of the top of the workbench 1. A slide rod 402 is fixedly connected between the same end of the two rectangular plates 401. A positioning block 403 is slidably sleeved at the same end of the two slide rods 402. A round hole adapted to the slide rod 402 is opened at both ends of each positioning block 403. A V-shaped groove 404 is opened on the side of the two positioning blocks 403 that are close to each other.
[0024] With the above structure, the positioning mechanism 4 also includes a fixed rod 405 fixedly connected to the bottom of the worktable 1 directly below the measuring mechanism 3. A first rotating rod 406 is rotatably connected to the fixed rod 405, and a second rotating rod 407 is rotatably connected to both ends of the first rotating rod 406. A sliding block 408 is rotatably connected to the top of each of the two second rotating rods 407, and each sliding block 408 is fixedly connected to the bottom of the positioning block 403. Sliding holes 101 adapted to the sliding blocks 408 are opened on both sides of the top of the worktable 1, and support plates are fixedly connected to both sides of the bottom of the worktable 1. Through the arrangement of the first rotating rod 406, the sliding block 408 and the second rotating rod 407, the two positioning blocks 403 can move closer and further away simultaneously.
[0025] The working principle of this embodiment is as follows: When using this device, the inner diameter of the roller to be measured is placed in the center of the worktable 1. One positioning block 403 is pushed, and under the action of the first rotating rod 406, two second rotating rods 407, and the sliding block 408, the two positioning blocks 403 move closer together synchronously. Under the action of the V-groove 404, the roller is positioned in the exact center. At this time, the center of the roller and the center of the two measuring claws 312 are on the same vertical line. Then, the knob at the top of the lead screw 305 is rotated, causing the rectangular cover 307 and the U-shaped plate 302 to descend. When the measuring claw 312... When 12 contacts the top of the worktable 1, as the U-shaped plate 302 continues to descend, the rectangular cover 307 will no longer descend and will slide along the U-shaped rod 315. The U-shaped plate 302 continues to descend with the fixing plate 306. During this process, the two drive rods slide in the inclined hole 311 respectively. At this time, the two measuring claws 312 separate from each other until both measuring claws 312 are in contact with the inner wall of the roller plate. At this time, stop rotating the knob at the bottom of the lead screw 305. The head work pointer 313 and the scale line 314 cooperate to directly read the value. The value on the scale line 314 is matched with the distance between the outer ends of the two measuring claws 312.
