Description

Technical Field

[0001] This utility model relates to the field of clamping devices, and in particular to a measuring instrument cartridge clamping device. Background Technology

[0002] The cartridge case clamping device of the measuring instrument is a device that clamps and fixes the cartridge case when the measuring instrument is measuring and testing it. It can firmly position the cartridge case and assist the use of the measuring instrument. It is widely used in cartridge case measurement.

[0003] However, existing clamping devices typically employ a fixed clamping structure, which cannot dynamically adjust the clamping position or clamping force according to the cartridge case size. When encountering large-caliber, irregularly shaped, or non-standard cartridge cases, specialized clamping hardware must be replaced, leading to operational interruptions, poor compatibility, and increased spare parts costs. Furthermore, the number and spacing of clamping rods are mostly fixed designs, making it impossible to quickly add or remove clamping points according to the cartridge case diameter. When measuring cartridge cases of different specifications, the entire clamping module must be repeatedly disassembled and reassembled, significantly extending preparation time and reducing production line throughput. In addition, traditional clamping structures are mostly integrated designs, requiring the entire device to be disassembled for maintenance to clean or replace worn parts. The non-modular structure results in long downtime, high maintenance costs, and difficulty in quickly restoring production. Utility Model Content

[0004] The main objective of this invention is to provide a measuring instrument cartridge case clamping device, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A measuring instrument cartridge case clamping device includes a fixed base and a connecting plate. The connecting plate is fixedly installed on the upper end of the fixed base. A clamping ring is fixedly installed on the upper end of the connecting plate. An installation block is fixedly installed on the outer side of the clamping ring. An air pipe connector is fixedly installed on one side of the installation block. A sliding groove ring is fixedly installed on the inner wall of the clamping ring. Multiple clamping rod structures are slidably installed on the inner side of the sliding groove ring.

[0007] As a further embodiment of this utility model, a fixed top cover is fixedly installed on the upper end of the clamping ring, and multiple diverter connectors are fixedly installed on the outer side of the mounting block.

[0008] As a further embodiment of this utility model, the outer sides of both the clamping ring and the sliding ring are provided with mounting grooves, which extend through to the inner sides of the clamping ring and the sliding ring.

[0009] As a further embodiment of this utility model, the clamping rod structure includes a sliding block, an insert plate, a mating block, an input connector, a mounting sleeve, and a telescopic rod. The sliding block is slidably installed on the inner side of the sliding groove ring, the insert plate is fixedly installed on one side of the sliding block, the mating block is inserted into the inner side of the insert plate, the input connector is fixedly installed on the upper end of the mating block, the mounting sleeve is fixedly installed on one side of the mating block, and the telescopic rod is movably installed on one end of the mounting sleeve.

[0010] As a further embodiment of this utility model, the sliding block slides around the inner side of the sliding groove ring, and the telescopic rod is inserted into the mounting sleeve rod for telescopic movement. The mounting sleeve rod and the telescopic rod are located inside the clamping ring.

[0011] As a further embodiment of this utility model, a connecting rod is fixedly installed on the inner wall of the sliding ring, and a positioning ring is fixedly installed at the end of the connecting rod away from the sliding ring. The positioning ring and the clamping ring are arranged concentrically, and the mounting sleeve passes through the positioning ring.

[0012] Compared with the prior art, this utility model has the following advantages: The clamping rod structure is slidably installed inside the sliding groove ring via a sliding block, which can adjust the clamping position. Combined with the mounting groove design, the position and number of telescopic rods can be adjusted. The telescopic rods can extend and retract within the mounting sleeve rod to accommodate cartridge cases of different sizes. This allows the device to flexibly handle various cartridge case sizes and achieve rapid adjustment without replacing hardware. During the operation of the measuring instrument, the number of clamping rods can be increased or decreased according to the cartridge case diameter, avoiding compatibility issues caused by traditional fixed clamping, improving the versatility and measurement range of the device. At the same time, during maintenance, the clamping rod structure can be easily disassembled for cleaning or replacement of parts, reducing downtime costs. The modular design supports spare parts replacement and extends the life of the device. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a measuring instrument cartridge case clamping device is described; please refer to it carefully. Figures 1-4 It includes a fixed base 1 and a connecting plate 2. The connecting plate 2 is fixedly installed on the upper end of the fixed base 1. A clamping ring 3 is fixedly installed on the upper end of the connecting plate 2. An installation block 4 is fixedly installed on the outer side of the clamping ring 3. An air pipe connector 5 is fixedly installed on one side of the installation block 4. A sliding groove ring 8 is fixedly installed on the inner wall of the clamping ring 3. Multiple clamping rod structures 9 are slidably installed on the inner side of the sliding groove ring 8.

[0020] Please refer to this carefully. Figure 1 and Figure 2 A fixed top cover 7 is fixedly installed on the upper end of the clamping ring 3, and multiple diversion connectors 6 are fixedly installed on the outer side of the mounting block 4.

[0021] Specifically, the fixed top cover 7 reinforces the clamping ring 3, and the air pipe connector 5 on one side of the mounting block 4 is used to install the air pipe for inputting air, and then the air is discharged from the split connector 6.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 The clamping ring 3 and the sliding ring 8 are both provided with mounting grooves on their outer sides, and the mounting grooves extend to the inner sides of the clamping ring 3 and the sliding ring 8.

[0023] Specifically, the clamping rod structure 9 passes through the mounting groove to assemble and disassemble with the sliding ring 8 inside the clamping ring 3.

[0024] Please refer to this carefully. Figures 2-4 The clamping rod structure 9 includes a sliding block 10, an insert plate 11, a mating block 12, an input connector 13, an mounting sleeve 14, and a telescopic rod 15.

The mounting sleeve 14 and the telescopic rod 15 are located inside the clamping ring 3.

[0026] Specifically, the input connector 13 and the diverter connector 6 are connected by an air pipe, so that the air discharged from the diverter connector 6 enters the input connector 13, and then the air enters the mounting sleeve 14 through the insertion block 12, so that a high pressure is formed in the mounting sleeve 14 to push the telescopic rod 15 outward. The cartridge case is placed in the middle of multiple telescopic rods 15, and the cartridge case is clamped and fixed by the telescopic rods 15. At the same time, the position of the telescopic rods 15 is adjusted by the sliding block 10 sliding around the inner side of the sliding groove ring 8. The number of telescopic rods 15 can be adjusted by the sliding block 10 passing through the mounting groove of the clamping ring 3 and the sliding groove ring 8.

[0027] Please refer to this carefully. Figure 2 and Figure 3 A connecting rod 16 is fixedly installed on the inner wall of the sliding ring 8.
