Description

Technical Field

[0001] The utility model relates to the technical field of jigs for processing photoelectric measuring instruments, and more specifically, to a jig for processing photoelectric measuring instruments. Background Art

[0002] In existing technologies, the processing jigs of photoelectric measuring instruments are key tools to ensure processing quality and accuracy. However, these jigs face a challenge in practical applications: due to the diverse designs of the housings of photoelectric measuring instruments, existing jigs often cannot adapt to the sizes and shapes of different housings. This results in limited versatility of the jigs, which cannot adapt to various housings by replacing the contact plate, thus affecting processing efficiency and adaptability.

[0003] Specifically, the housing design of photoelectric measuring instruments is usually customized according to their application and functional requirements, which results in different sizes, shapes and interfaces of the housing. However, existing processing jigs are often designed based on specific models or standard housings, which means that they may not be directly applicable to photoelectric measuring instruments with different housings. This mismatch leads to inconvenience in the processing process because the operator needs to prepare corresponding jigs for each housing type, which not only increases costs but also reduces production efficiency.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a jig for photoelectric measuring instrument processing, which has the following beneficial effects:

[0017] 1. The design of the replacement mechanism enables the photoelectric measuring instrument processing jig to adapt to photoelectric measuring instruments with different shells. Through the cooperation of the cylinder, the extension sleeve, the fixed sleeve, the contact plate, the ejector rod, the contraction mechanism and the adjustment mechanism, the replacement mechanism can realize the rapid replacement of the contact plate to adapt to the size and shape of different shells.

A replacement mechanism is arranged on the support frame 1, and the replacement mechanism comprises a cylinder 2, an extension sleeve 3, a fixed sleeve 4, a contact plate 5, a push rod 6, a contraction mechanism, a block 7 and an adjustment mechanism. The cylinder 2 is mounted on the support frame 1, the extension sleeve 3 is mounted on the extension section of the cylinder 2, the fixed sleeve 4 is threadedly connected in the extension sleeve 3, the push rod 6 is coaxially connected in the fixed sleeve 4, the contact plate 5 is mounted on the push rod 6, and the contact plate 5 is pressed against the side wall of the photoelectric measuring instrument. The contraction mechanism is cooperatively connected to the fixed sleeve 4 and the block 7, an annular groove 8 is provided on the side wall of the push rod 6, and the block 7 is pressed against the annular groove 8, the adjustment mechanism is mounted on the fixed sleeve 4, and a round head 9 is provided on the push rod 6, and the round head 9 is pressed against the extension sleeve 3. The contraction mechanism comprises a slider 10 and a contraction sleeve 11, the contraction sleeve 11 is mounted in the fixed sleeve 4, the slider 10 is slidably connected to the contraction sleeve 11, and the block 7 is mounted on the slider 10. There are multiple sliders 10, each of which is provided with multiple springs 12, which are in contact with the annular groove 8. A limit plate 13 is coaxially provided on the fixed sleeve 4, and the limit plate 13 is fitted on the extension sleeve 3. The adjustment mechanism includes a conical plate 14 and a spiral sleeve 15. Each slider 10 is equipped with a conical plate 14, and the spiral sleeve 15 and the fixed sleeve 4 are coaxially arranged. Multiple conical plates 14 are fitted on the side wall of the spiral sleeve 15, and a plurality of contraction grooves 16 are opened on the side wall of the fixed sleeve 4. The conical plate 14 is slidably connected in the contraction groove 16, a conical strip 17 is provided on the spiral sleeve 15, and multiple conical plates 14 are respectively engaged with the conical strip 17. An inner sleeve 18 is provided in the fixed sleeve 4, and a follower sleeve 19 is coaxially provided on the threaded sleeve 21. Thrust bearings 20 are respectively provided at both ends of the follower sleeve 19.

The push rod 6 is slidably connected to the threaded sleeve 21, and two blocks 22 are provided on the support frame 1.

[0030] In this embodiment, when it is necessary to replace the corresponding abutment plate 5 for different photoelectric measuring instruments, first insert the corresponding push rod 6 into the spiral sleeve 15, then make the block 7 and the annular groove 8 in parallel positions, and then rotate the spiral sleeve 15. Since the spiral sleeve 15 on the threaded sleeve 21 is engaged with multiple conical plates 14, and the block 7 and the shrinkage groove 16 are in a parallel state, it will drive multiple sliders 10 to slide along the shrinkage sleeve 11, so that the block 7 is abutted in the annular groove 8, and then it is fixed, thereby completing the fixing process of the abutment plate 5. Since there are thrust bearings 20 on both sides of the follower sleeve 19, the spiral sleeve 15 can be limited to rotation but not sliding up and down under the action of the threaded sleeve 21 and the inner sleeve 18, thereby ensuring the engagement between the conical bar 17 and the conical plate 14, and then completing the adjustment process.

[0031] More specifically, when the photoelectric measuring instrument needs to be fixed, one side of the photoelectric measuring instrument is first clamped on the stopper 22, and then the cylinder 2 drives the resistance plate 5 to press against the other side of the photoelectric measuring instrument, thereby completing the fixing process, and then performing corresponding operations.

[0032] In summary, when the overall equipment is in use or running: when it is necessary to replace the corresponding resistance plate 5 for different photoelectric measuring instruments, first insert the corresponding push rod 6 into the spiral sleeve 15, then make the block 7 and the annular groove 8 in a parallel position, and then rotate the spiral sleeve 15. Since the spiral sleeve 15 on the threaded sleeve 21 is engaged with multiple conical plates 14, and the block 7 and the shrinkage groove 16 are in a parallel state, it will drive multiple sliders 10 to slide along the shrinkage sleeve 11, so that the block 7 is in contact with the annular groove 8, and then it is fixed, thereby completing the fixing process of the resistance plate 5. Since there are thrust bearings 20 on both sides of the follower sleeve 19, the spiral sleeve 15 can be limited to rotate but not slide up and down under the action of the threaded sleeve 21 and the inner sleeve 18, thereby ensuring the engagement between the conical bar 17 and the conical plate 14, and then completing the adjustment process.

[0033] When the photoelectric measuring instrument needs to be fixed, first one side of the photoelectric measuring instrument is clamped on the stopper 22, and then the cylinder 2 drives the contact plate 5 to press against the other side of the photoelectric measuring instrument, thereby completing the fixing process, and then performing corresponding operations.
