Description

Technical Field

[0001] This invention relates to a roller inspection device with an internal step, belonging to the field of machining technology. Background Technology

[0002] A winch is a drum that is rotated by human or mechanical power. Steel wire rope or cable is wound on the drum. The inner side of one end of some drums usually needs to be press-fitted with powder metallurgy ring parts and gear rings. Press-fitting requires opening a step on the inner side of one end of the drum to limit the drum. The adjustment of the step needs to be adapted to the powder metallurgy ring parts and gear rings, which requires high precision. Therefore, after opening the step, the inner diameter of the step needs to be tested.

[0003] Chinese patent application CN105004248A discloses an efficient inner diameter detection device, comprising: a base frame and a movable frame. A first sliding sleeve is vertically arranged on the rear end of the base frame, and a second sliding sleeve is vertically arranged on the front end of the movable frame. A first measuring rod is arranged inside the first sliding sleeve, and a second measuring rod is arranged inside the second sliding sleeve. A first measuring foot is arranged at the bottom of the first measuring rod, and a second measuring foot is arranged at the bottom of the second measuring rod corresponding to the first measuring foot. A sleeve is vertically arranged on the inner side of the second measuring foot, and a sliding rod pointing to the sleeve is arranged on the inner side of the first measuring foot.

[0004] The aforementioned testing device requires a single inspection of each part, involves multiple inspection steps, and cannot inspect the outer diameter of the workpiece. When multiple workpieces need to be inspected, the inspection time is even longer and the efficiency is even lower. Summary of the Invention

[0005] The purpose of this invention is to provide a roller detection device with an inner step, which solves the problems of multiple detection steps and low detection efficiency in the existing technology.

[0016] Figure 2 yes Figure 1 A structural sectional view. Detailed Implementation

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1 As shown, a roller inspection device with an inner step includes a worktable 3. On the worktable 3, a first inspection component for inspecting one end of the roller workpiece, a second inspection component for inspecting the outer diameter of the roller workpiece, and a third inspection component for inspecting the other end of the roller workpiece are arranged in parallel.

The bottom of the discharge port 32 is connected to a storage cart 321.

[0020] After the roller workpiece is placed on the first inspection component for inspection, the gripper cylinder moves to the first inspection component driven by the first and second rodless cylinders, and grips the roller workpiece. Then, the roller workpiece is rotated by the rotary cylinder, and transferred to the second inspection component again by the first and second rodless cylinders. The gripper cylinder releases the roller workpiece. After the roller workpiece is inspected on the second inspection component, the gripper cylinder moves to the second inspection component driven by the first and second rodless cylinders and grips the roller workpiece. Then, the roller workpiece is transferred to the third inspection component for inspection by the first and second rodless cylinders. Defective roller workpieces slide from the discharge port into the storage cart for storage, so as to be reused.

[0021] like Figure 1-2As shown, the first and third detection components have the same structure. The first detection component includes a bracket 33 mounted above the workbench 3. A fixed cylinder 331 is provided on the top of the bracket 33. A through hole 332 communicating with the fixed cylinder 331 is provided on the bracket 33. An annular support portion 333 is provided at the inner edge of the bottom end of the fixed cylinder 331. A pneumatic measuring instrument 34 is provided below the fixed cylinder 331. A fixed seat 35 is provided on the workbench 3 corresponding to the lower part of the bracket 33. A first drive for driving the pneumatic measuring instrument 34 to move up and down is provided in the middle of the fixed seat 35. The first driving cylinder 351 has its output end facing upwards and connected to the bottom of the pneumatic measuring instrument 34. At least one guide rod 352 is mounted on the fixed base 35, with its top end connected to the bottom of the pneumatic measuring instrument 34 and its bottom end equipped with a limiting plate 353. A second detection assembly is located between the first and third detection assemblies. The second detection assembly includes a movable base 36 that can move up and down, and a first detection plate 371 and a second detection plate 372 respectively located on both sides of the movable base 36. The top is provided with a V-shaped groove 361, and both the first detection plate 371 and the second detection plate 372 are provided with arc-shaped grooves 373. The axial direction of the V-shaped groove 361 and the axial direction of the arc-shaped groove 373 are arranged in the same direction. One end of the top of the arc-shaped groove 373 is provided with a flip-up arc-shaped pressure block 374. At the connection between the end of the arc-shaped pressure block 374 and the end of the arc-shaped groove 373, there is a micro motor 375 for driving the arc-shaped pressure block 374 to flip up and down. A support pad 376 is provided at the arc-shaped edge of the arc-shaped groove 373. The inner part of the arc-shaped groove 373... The wall is provided with air holes 377 that penetrate downward through the first detection plate 371 and the second detection plate 372. Below the movable seat 36 is a guide seat 362 that is connected to the side wall of the worktable 3. The bottom of the guide seat 362 is provided with a second drive cylinder 363. The output rod of the second drive cylinder 363 is connected upward to the bottom of the movable seat 36. The side wall of the worktable 3 is provided with linear guide rails 364 on both sides corresponding to the guide seat 362. The bottom of the movable seat 36 is provided with a connecting slider 365 that is connected to the linear guide rails 364.

[0022] The aforementioned pneumatic gauges are currently available products on the market and are existing technology, so they will not be described in detail here. The pneumatic gauges of the first detection component, the third detection component, and the pneumatic gauges connected to the air vents are connected by air pipes and centrally connected to the same control terminal for detection control, unified data analysis and calculation. The aforementioned air vents are connected to the externally installed pneumatic gauges to allow gas flow, so as to facilitate the detection of the outer diameter of the roller workpiece. After the roller workpiece is placed in the fixed cylinder on the first or third detection component, the end of the roller workpiece abuts against the annular support. The first drive cylinder is activated, driving the pneumatic gauge to move upward to the inner side of the end of the roller workpiece and automatically start detecting the inner diameter of one end of the roller workpiece. The guide rod moves on the fixed seat with the movement of the pneumatic gauge.

[0023] When the roller workpiece is placed on the second detection component, it is placed laterally in the V-shaped groove at the top of the movable seat, with the V-shaped groove higher than the arc groove. After the roller workpiece is placed in a suitable axial position on the V-shaped groove, the second drive cylinder is activated, driving the movable seat to move down along the linear guide rail via the connecting slider until the V-shaped groove is lower than the arc groove, so that the roller workpiece is supported by the arc groove on the first and second detection plates. The second drive cylinder stops driving, and the micro motor starts, rotating the arc-shaped pressure block until the arc-shaped pressure block presses down on the upper side of the roller workpiece, and the lower side of the roller workpiece contacts the support pad on the arc groove. The support pad is made of rubber or silicone material. Then, the external pneumatic gauge connected to the air hole is activated and the outer diameter of the roller workpiece is detected through the air hole. After the detection is completed, the micro motor controls the arc-shaped pressure block to flip again, canceling the pressing on the roller workpiece.
