Description

Technical Field

[0001] This utility model relates to the field of plug gauge technology, specifically a novel plug gauge. Background Technology

[0002] In the manufacturing and inspection industry of mechanical parts, plug gauges are commonly used to inspect the inner diameter of holes with high precision requirements on parts. Through simple operation, they can quickly and accurately determine whether the diameter of the inspected hole meets design requirements. Plug gauges are mainly used to check position, measure hole size, check the distance between two holes, and can also be used as go / no-go gauges and to measure hole depth. They are essential inspection tools for standardized hole inspection. Commonly used types include cylindrical plug gauges and threaded plug gauges. Cylindrical plug gauges are used to check the diameter of holes, while threaded plug gauges are tools for measuring the accuracy of internal thread dimensions.

[0003] Traditional plug gauges typically employ a design with a single or double-ended fixed probe, meaning that a fixed-specification probe is mounted at each end of the handle. The number of probes is limited by the structural layout. This design has significant limitations when dealing with batch testing tasks of multiple specifications. When measuring different hole diameters or groove widths, operators must frequently change plug gauges, leading to interruptions in the measurement process, increased complexity in tool management, and a significant reduction in measurement efficiency. Furthermore, repeated disassembly and assembly can easily cause probe wear or positioning errors, affecting measurement results. In addition, the handle length is not adjustable, making it inconvenient to suit the usage habits of different users. Utility Model Content

[0004] The purpose of this invention is to provide a new type of plug gauge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel plug gauge, comprising: a handle; a mounting frame, the mounting frame being fixedly mounted on the bottom of the handle, a rotating roller being rotatably mounted between the two sides of the inner wall of the mounting frame, and multiple plug gauge probes of different specifications being fixedly mounted in a circular array on the outer periphery of the rotating roller; a positioning component, the positioning component being mounted on the mounting frame and used to position and fix the rotating roller; and a sliding sleeve, the sliding sleeve being slidably sleeved on the outer periphery of the handle, and a fixing component being mounted on the handle for fixing the position of the sliding sleeve.

[0006] Furthermore, the positioning component includes a circular plate fixedly installed on one side of the rotating roller, the circular plate having multiple slots, a fixed frame fixedly installed on one side of the mounting frame, a locking plate slidably installed between the two sides of the inner wall of the fixed frame, multiple return springs fixedly installed between the top of the locking plate and the top of the inner wall of the fixed frame, a pull plate fixedly installed on the top of the locking plate, and one end of the locking plate penetrating the fixed frame and engaging with one of the slots.

[0007] Furthermore, the fixing component includes a threaded rod threadedly installed at the bottom end of the sliding sleeve plate, and a plurality of threaded holes are fixedly installed on the handle in an array, with the threaded rod threadedly connected to one of the threaded holes.

[0008] Furthermore, the handle is provided with a placement groove, inside which a cleaning brush is placed, and a sealing plate is detachably installed on the placement groove.

[0009] Furthermore, two iron blocks are fixedly installed on one side of the handle, and two magnets are fixedly installed on one side of the sealing plate, with the two magnets magnetically connected to the two iron blocks respectively.

[0010] Furthermore, multiple threaded cylinders are fixedly installed on the outer periphery of the rotating roller, and a screw is fixedly installed at one end of each of the multiple plug gauge probes, with the multiple screws respectively threaded into the multiple threaded cylinders.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a novel plug gauge according to one embodiment of the present invention includes: a handle 1;

[0023] Mounting frame 2 is fixedly mounted on the bottom of handle 1. Rotating roller 3 is rotatably mounted between the two sides of the inner wall of mounting frame 2. Multiple plug gauge probes 4 of different specifications are fixedly mounted in a ring array on the outer periphery of rotating roller 3.

[0024] Positioning component 5, which is mounted on the mounting frame 2, is used to position and fix the rotating roller 3.

[0025] A sliding sleeve 6 is slidably sleeved on the outer periphery of the handle 1, and a fixing component 7 for fixing the position of the sliding sleeve 6 is installed on the handle 1.

[0026] The working principle of this invention is as follows: When it is necessary to measure the diameter of holes or the width of grooves of different specifications, the operator holds the handle 1 and releases the locking of the rotating roller 3 by the positioning component 5, so that the rotating roller 3 can rotate freely within the mounting frame 2. At this time, according to the specification requirements of the workpiece to be measured, the selected plug gauge probe 4 from the multiple plug gauge probes 4 of different specifications distributed in a ring array on the outer periphery of the rotating roller 3 is rotated to the required vertical downward position. Then, the rotating roller 3 is relocked by the positioning component 5 to ensure that the selected probe remains in a fixed position during operation and avoids deviation during measurement. At the same time, the sliding sleeve 6 can slide axially along the outer periphery of the handle 1, and its position on the handle 1 can be adjusted by the fixing component 7 to adapt to the different length gripping habits or measurement space requirements of different operators. Thus, while ensuring measurement accuracy, it can realize the rapid switching and positioning of multiple specification probes. This device effectively solves the problem of frequent replacement caused by the limited number of probes in traditional plug gauges, significantly improves the efficiency and operation convenience of multi-specification batch inspection tasks, reduces the complexity of tool management and the risk of probe wear, and ensures the accuracy and stability of measurement results.

[0027] like Figure 4 As shown, in some embodiments, the positioning component 5 includes a circular plate 51 fixedly installed on one side of the rotating roller 3. The circular plate 51 has multiple slots. A fixing frame 52 is fixedly installed on one side of the mounting frame 2. A locking plate 53 is slidably installed between the two sides of the inner wall of the fixing frame 52. Multiple return springs 54 are fixedly installed between the top of the locking plate 53 and the top of the inner wall of the fixing frame 52. A pull plate 55 is fixedly installed on the top of the locking plate 53. One end of the locking plate 53 passes through the fixing frame 52 and engages with one of the slots.

[0028] By gripping the handle 1 and pulling the plate 55 upward, the clamping plate 53 slides upward within the fixed frame 52 against the elastic force of the return spring 54, thereby releasing the clamping state between the clamping plate 53 and the corresponding slot on the circular plate 51. At this time, the locking of the rotating roller 3 is released, and the operator can freely rotate the rotating roller 3 to rotate the multiple plug gauge probes 4 of different specifications distributed in a ring array on its outer periphery to the required measurement position. Then, the pull plate 55 is released, and the elastic force of the return spring 54 drives the clamping plate 53 to slide downward, so that its end is reinserted into the corresponding slot on the circular plate 51, forming a precise positioning of the rotating roller 3, ensuring that the selected probe maintains a fixed posture during the measurement process and avoiding deviation or shaking.

[0029] like Figure 3 As shown, in some embodiments, the fixing component 7 includes a threaded rod 71 threadedly mounted to the bottom end of the sliding sleeve 6, and a plurality of threaded holes are fixedly mounted on the handle 1 in an array, with the threaded rod 71 threadedly connected to one of the threaded holes.

[0030] The sliding sleeve 6 can slide axially along the outer periphery of the handle 1. By rotating the threaded rod 71, it can be threadedly connected to the threaded holes at different positions on the handle 1, thereby fixing the sliding sleeve 6 in the required position to adapt to the grip length habits or measurement space requirements of different operators.

[0031] like Figure 2-3 As shown, in some embodiments, the handle 1 is provided with a placement groove 8, a cleaning brush 9 is placed inside the placement groove 8, and a sealing plate 10 is detachably installed on the placement groove 8.

[0032] During the measurement process, if foreign matter adheres to the surface of the plug gauge probe 4 and affects the measurement accuracy, the operator can remove the sealing plate 10, take out the cleaning brush 9 from the placement slot 8 to clean the probe, and after cleaning, put the cleaning brush 9 back into the placement slot 8 and reinstall the sealing plate 10. When it is necessary to remove the sealing plate 10, first move the sliding sleeve 6 to the top of the handle 1 to avoid affecting the removal of the sealing plate 10.

[0033] like Figure 5 As shown, in some embodiments, two iron blocks 11 are fixedly installed on one side of the handle 1, and two magnets 12 are fixedly installed on one side of the sealing plate 10. The two magnets 12 are magnetically connected to the two iron blocks 11 respectively.

[0034] The sealing plate 10 is quickly fixed by the magnetic attraction between the magnet 12 and the iron block 11. The sealing plate 10 has a groove. Simply insert your finger into the groove and press the sealing plate 10 to remove it from the placement slot 8 and release the magnetic connection between the magnet 12 and the iron block 11.

[0035] like Figure 3 As shown, in some embodiments, a plurality of threaded cylinders 13 are fixedly installed on the outer periphery of the rotating roller 3, and a screw 14 is fixedly installed on one end of each of the plurality of plug gauge probes 4, and the plurality of screws 14 are respectively threaded into the plurality of threaded cylinders 13.

[0036] When it is necessary to replace or maintain the plug gauge probe 4, the operator can rotate the screw 14 at the end of the plug gauge probe 4 to make it unscrew from the threaded cylinder 13 on the outer periphery of the rotating roller 3, thereby quickly disassembling and replacing the probe of the required specification, further improving the convenience of tool maintenance and service life.

[0037] like Figure 3 As shown, in some embodiments, a handle 15 is fixedly installed on the top of the sliding sleeve 6, and two auxiliary plates 16 are symmetrically distributed and fixedly installed on the top of the sliding sleeve 6. The auxiliary plates 16 are used to stably press down the plug gauge when operating with both hands.

[0038] The handle 15 facilitates handling during transport. When the plug gauge probe 4 is aligned with the measuring hole, the two auxiliary plates 16 are dragged by both hands to make the entire device move down smoothly, allowing the plug gauge probe 4 to enter the measuring hole stably.

[0039] like Figure 3 As shown, in some embodiments, connecting plates 17 are fixedly installed on both sides of the mounting frame 2, and support plates 18 are slidably installed on one side of each of the two connecting plates 17. At least two first springs 19 are fixedly installed between the support plates 18 and the connecting plates 17.

[0040] During measurement, the connecting plates 17 and support plates 18 on both sides of the mounting frame 2 form an elastic support structure through the first spring 19, facilitating the stable vertical downward movement of the plug gauge probe 4. When the plug gauge probe 4 contacts the workpiece, the connecting plate 17 slides on the support plate 18 and stretches the first spring 19, thereby buffering the impact force during measurement and avoiding damage to the probe or workpiece caused by rigid contact. This ensures the stability and safety of the measurement process and further improves the ease of tool maintenance and service life. After measurement, the rebound force of the first spring 19 will automatically move the handle 1 and the plug gauge probe 4 upward, eliminating the need for manual pulling and reducing the labor intensity of the workers.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
