Description

Technical Field

[0001] This utility model relates to the field of industrial inspection, specifically a deep hole position gauge with an illumination device. Background Technology

[0002] A deep hole position gauge with illumination is designed to solve the problem of positional accuracy testing in dimly lit deep holes. Based on the traditional position gauge, it integrates a dedicated light source, which illuminates the hole with bright light, allowing the operator to clearly, quickly, and accurately determine whether the position of the deep hole center meets the design requirements, significantly improving the efficiency and reliability of inspection.

[0003] In current deep hole positioning gauges, when measuring the inner wall of a hole, the measuring personnel usually insert the measuring rod into the inner diameter of the hole. Due to the viewing angle, the measuring personnel may not be able to clearly see the inner wall, leading to measurement errors. Therefore, there is an urgent need for inventors to develop a device with illumination to facilitate observation by the measuring personnel. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a deep hole position gauge with an illumination device to solve the technical problem that poor lighting affects the measurement results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep hole position gauge with an illumination device, comprising a measuring rod and a protective device. A connecting rod is sleeved on the outer side of the measuring rod, and several sets of grooves are formed on the outer wall of the connecting rod. Several lamp tubes are installed on the inner wall of the several sets of grooves. The protective device includes a protective cover, and two sets of locking blocks are fixedly connected to the surface of the protective cover. A connecting cover is slidably connected to the upper side of the protective cover, and two sets of locking slots are formed on the surface of the connecting cover. A fixing rod passes through the middle of the protective device, and a refractive plate is installed on the inner wall of the protective cover.

[0006] By adopting the above technical solution, through the sleeve structure of the measuring rod and the connecting rod, and the design of embedding the lamp tube in the groove of the connecting rod, the active lighting function in the deep hole measurement environment is realized, which solves the problem that traditional position gauges cannot clearly observe the contact state between the measuring rod and the hole wall in dark deep holes.

[0007] Furthermore, a display panel is sleeved on the outer side of the fixing rod, and a fixing box is fixedly connected to the back of the display panel. A sliding groove is formed on the surface of the fixing box, and a switch button is slidably connected to the inner wall of the sliding groove.

[0008] By adopting the above technical solution, the integrated design of the fixed rod display panel and sliding switch concentrates lighting control and measurement feedback into a compact module that can be operated with one hand, greatly improving the efficiency of human-computer interaction.

[0009] Furthermore, several sets of the grooves are evenly distributed around the circumference to increase the distribution area of ​​the lamp tubes.

[0010] By adopting the above technical solution, the evenly distributed groove layout around the circumference allows the lamp tube's radiation range to cover a 360° annular space, completely eliminating the lighting shadow dead angles on the inner wall of the deep hole.

[0011] Furthermore, the power supply inside the fixing box is electrically connected to several lamp tubes via fixing rods.

[0012] By adopting the above technical solution, the rigid conductive structure of the fixing box transmitting electrical energy to the lamp tube through the fixing rod avoids the risk of poor contact caused by the tangling of traditional wires, and ensures the current stability of the lighting system under the condition of repeated plugging and unplugging of tools.

[0013] Furthermore, the protective cover moves up and down, and the position of the protective cover is limited by the cooperation of the locking blocks and the locking slots. The two sets of locking blocks engage with the two sets of locking slots through their own elasticity.

[0014] The combination of the measuring rod and connecting rod, along with the linearly arranged lamps within the groove, enables active illumination inside deep holes. The evenly distributed lamps eliminate blind spots, and the tilted refractor focuses the light onto the axis of the measuring rod, completely resolving the blind spot problem caused by insufficient light in traditional gauges. The protective cover and connecting cover are engaged by a flexible locking block and slot, allowing for one-handed adjustment of the protective height and locking of the position. In the non-working state, the cover completely encloses the lamp array, preventing machining debris from corroding the optical components and significantly improving the tool's durability under harsh working conditions.

[0015] Furthermore, several lamps are arranged in a straight line and are uniformly distributed, and the protective device is in an unfolded state to protect the several lamps.

[0016] By adopting the above technical solution, the coordinated design of the linear array of lamps and the unfolded state of the protective cover allows all lamps to be fully exposed after the protective cover is raised, forming a maximum lighting coverage area; while in the retracted state, the cover seamlessly covers the lamps to avoid physical damage.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model achieves active illumination inside deep holes by combining a measuring rod and a connecting rod with linearly arranged lamps in the groove. The evenly distributed lamps eliminate blind spots, and the tilted refraction plate focuses the light onto the axis of the measuring rod, completely solving the problem of blind spots caused by insufficient light in traditional gauges. The protective cover and connecting cover are engaged by the sliding engagement of elastic blocks and slots, allowing for one-handed adjustment of the protective height and locking of the position. In the non-working state, the lamp array is completely covered, facilitating the observation of the inside of the hole by the staff.

[0019] 2. This utility model uses a through-type structure to connect the display panel and the fixed box with a fixing rod, so that the switch button in the sliding groove can control the lighting with one hand. The power supply in the fixed box is directly conducted to the lamp tube through the rigid fixing rod, avoiding the risk of wire aging. The display panel provides real-time feedback of measurement data. Combined with the shadowless lighting environment, key information such as hole wall burrs and position deviations are displayed with high clarity, significantly reducing the misjudgment rate and improving the detection efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this embodiment: a deep hole position gauge with an illumination device, such as... Figure 1-4As shown, the device includes a measuring rod 1 and a protective device 3. A connecting rod 2 is sleeved on the outer side of the measuring rod 1. Several sets of grooves 201 are formed on the outer wall of the connecting rod 2. Several lamp tubes 202 are installed on the inner wall of the grooves 201. The protective device 3 includes a protective cover 301. Two sets of locking blocks 302 are fixedly connected to the surface of the protective cover 301. A connecting cover 303 is slidably connected to the upper side of the protective cover 301. Two sets of slots 304 are formed on the surface of the connecting cover 303. A fixing rod 4 passes through the middle of the protective device 3. A refractive plate 5 is installed on the inner wall of the protective cover 301. Through the sleeve structure of the measuring rod and the connecting rod, and the design of embedding lamp tubes in the grooves of the connecting rod, the active illumination function in the deep hole measurement environment is realized. This solves the problem that traditional position gauges cannot clearly observe the contact state between the measuring rod and the hole wall in dark deep holes. The multi-layer structure of the protective device forms a dynamic protective layer, which can prevent mechanical collision damage to the precision lamp tubes and significantly improve the durability of the tool in harsh industrial environments.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A display panel 9 is sleeved on the outer side of the fixing rod 4, and a fixing box 6 is fixedly connected to the back of the display panel 9. A sliding groove 7 is opened on the surface of the fixing box 6, and a switch button 8 is slidably connected to the inner wall of the sliding groove 7. The fixing rod integrates the display panel and the sliding switch into a single-handed operation, which concentrates the lighting control and measurement feedback into a compact module, greatly improving the efficiency of human-machine interaction. The built-in circuit of the fixing box supplies stable power to the lamp tube through the fixing rod to ensure flicker-free lighting. The sealed structure of the sliding groove switch avoids circuit failure caused by accidental touch or dust, ensuring the reliability of the function while maintaining the overall portability and smooth operation of the tool.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Several sets of grooves 201 are evenly distributed around the circumference to increase the distribution area of ​​several lamps 202. The evenly distributed groove layout around the circumference allows the lamp radiation range to cover the annular space, completely eliminating the lighting shadow dead angle of the inner wall of the deep hole. The uniform arrangement of multiple lamps in the axial and radial directions forms a composite light field, which makes the micro-morphology of the hole wall, such as burrs, scratches and the fit gap between the measuring rod and the hole wall, visually display with high contrast, providing distortion-free observation conditions for position determination, and fundamentally reducing the probability of subjective misjudgment.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4The power supply inside the fixing box 6 is electrically connected to several lamp tubes 202 through the fixing rod 4. The rigid conductive structure of the fixing box to transmit electrical energy to the lamp tubes through the fixing rod avoids the risk of poor contact caused by the tangling of traditional wires, and ensures the current stability of the lighting system under the condition of repeated plugging and unplugging of tools. All electrical connection components are hidden inside the rod, avoiding failures caused by corrosion or physical damage to the exposed interface. This simplifies the maintenance process and extends the service life of the core electronic components.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The protective cover 301 moves up and down, and the position of the protective cover is limited by the cooperation of the locking block 302 and the locking slot 304. The two sets of locking blocks 302 engage with the two sets of locking slots 304 through their own elasticity. The interference fit mechanism of the elastic locking blocks and locking slots of the protective cover allows for stepless adjustment of the protective height by pushing and pulling with one hand, so that the same tool can be used to measure holes with different depth-to-diameter ratios. The spring-type structure of the block generates a self-tightening effect under vibration conditions, preventing the risk of lamp exposure caused by accidental displacement of the protective cover, and ensuring the dynamic coordination between the protective state and the measurement action.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The refracting plate 5 has an inclined structure, which is used to focus the diffused light towards the axis of the measuring rod 1. The asymmetric optical design of the inclined refracting plate efficiently focuses the side-scattered light of the lamp tube to the axis of the measuring rod, so that the light is accurately projected along the depth of the deep hole, which greatly improves the utilization rate of the limited light source. The frosted surface of the refracting plate forms a soft light effect through secondary scattering, avoiding the strong reflection spot generated by direct light on the metal hole wall, so that the hole wall texture and the outline of the measuring rod are clearly imaged under uniform diffused light.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Several lamp tubes 202 are arranged in a straight line and are uniformly distributed. The protective device 3 is in an unfolded state to protect the lamp tubes 202. The coordinated design of the linear array of lamp tubes and the unfolded state of the protective cover allows all lamp tubes to be fully exposed after the protective cover is raised, forming a maximum lighting coverage area. When the lamp tubes are in the retracted state, the cover seamlessly covers the lamp tubes to avoid physical damage. The equidistant distribution of the tubes, together with the rigid support of the protective cover, allows the lighting system to resist radial impact during repeated insertion and removal of tools and maintain the permanent calibration state of the optical components.

[0033] The implementation principle of this embodiment is as follows: the measurement depth is adjusted by sliding the protective cover 301 up and down. The position is locked by the elastic engagement of the locking block 302 on its surface and the locking groove 304 on the connecting cover 303, so that the protective cover can adapt to the deep hole measurement range. Then, the power is turned on by pushing the switch button 8 along the sliding groove 7. The power supply in the fixing box 6 supplies power to the lamp tube 202 in the groove 201 of the connecting rod 2 through the fixing rod 4. The lamp tube array evenly distributed in the circumference emits light. At this time, the refraction plate 5 gathers the side-scattered light to the axial direction of the measuring rod 1, forming high-brightness illumination along the depth of the deep hole. When the protective device 3 is in the unfolded state, the linearly arranged lamp tubes 202 illuminate the hole wall without obstruction. The operator reads the fitting deviation data between the measuring rod and the hole wall in real time through the display panel 9 to complete the deep hole position accuracy detection.
