Description

Technical Field

[0001] This utility model belongs to the field of bore inspection technology, specifically relating to a fully automatic adjustable bore force bore inspection device. Background Technology

[0002] Previously, barrel fitting inspection involved manually handling the cartridge case and placing it into a gauge for inspection. This manual handling process was prone to bumps and knocks, causing damage to the cartridge case. Furthermore, because the cartridge case was manually pushed into the gauge, consistent force could not be guaranteed each time, leading to inaccurate test results. Different types of cartridge cases required different gauges, increasing the required floor space and resulting in wasted space. Utility Model Content

[0003] This invention aims to solve the problem of low automation in the inspection of gun barrel closure.

[0004] This utility model provides the following technical solution: a fully automatic adjustable bore force and bore engagement test device, including a stand and several bore engagement test units, with the several bore engagement test units arranged on the stand;

[0005] The bore inspection unit includes a bore infeed mechanism, an internal support rotation mechanism, and a flat latch mechanism;

[0006] The flat latch mechanism includes a full profile gauge and a flat latch assembly. The infeed mechanism and the internal support rotation mechanism are located on the first port side and the second port side of the full profile gauge, respectively. The flat latch assembly is located at the first port of the full profile gauge.

[0007] The feeding mechanism includes a cartridge slide rail, a pushing assembly, and a cartridge lifting assembly. The feeding mechanism is guided and supported by the cartridge slide rail and feeds the cartridge into the full-form gauge through the pushing assembly. The driving end of the pushing assembly is also equipped with a movable claw hook for grabbing the bottom flange of the cartridge and driving the cartridge out. The cartridge lifting assembly is located in front of the first port of the full-form gauge and can raise the mouth of the cartridge on the cartridge slide rail to align with the full-form gauge.

[0008] The rotating shaft of the internal support rotating mechanism extends from the second port of the full-form gauge. The rotating shaft is coaxial with the full-form gauge, and the joint on the rotating shaft can engage with the cartridge to transmit torque or disconnect the contact.

[0009] Furthermore, the cartridge slide rail includes two V-shaped support ramps, which are spaced apart, and the drive end of the push assembly is located between the two support ramps.

[0010] Furthermore, the cartridge lifting assembly includes two clamping blocks, each connected to a lateral pushing element. The clamping ramps on the two clamping blocks correspond to the two supporting ramps of the cartridge slide rail. The lateral pushing element drives the two clamping blocks to move closer together, lifting the cartridge through the supporting ramps.

[0011] Furthermore, the upper part of the driving end of the push component is a push backrest, and the lower part is a movable claw hook, which includes a vertical pushing element and a hook body.

[0012] Furthermore, the measuring latch assembly includes a measuring scale and a torque output element. The support shaft of the measuring scale is mounted on the top of the first port of the full profile gauge, and the torque output element is mounted on a bracket connected to the test bench. A residual circular gear ring coaxial with the support shaft is connected to the measuring scale, and the gear on the torque output element meshes with the residual circular gear ring.

[0013] Furthermore, the joint on the rotating shaft is an internal support cylinder.

[0014] Furthermore, the test bench has several chamber fitting inspection units that include two or more testing specifications.

[0015] Furthermore, the inner support rotation mechanism and the measuring flat latch mechanism are covered by an organic housing.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model provides a fully automatic adjustable bore force testing device. By integrating a bore force feeding mechanism, an internal support rotation mechanism, and a leveling latch mechanism, it achieves fully automated, unmanned operation of the entire process, including automatic cartridge feeding, rotation detection, and retraction, significantly reducing manual intervention. The multi-unit parallel layout of the bench structure, combined with the coordinated action of the cartridge slide rail and lifting components, enables rapid batch testing, increasing production line throughput. Compared to traditional manual bore force testing, this device, through automation technology, achieves adjustable bore force for bore force testing, comprehensively solving problems such as low efficiency, high labor intensity, and poor quality consistency. The several bore force testing units on the bench include two or more testing specifications, enabling adaptation to different types of cartridges and ensuring that multiple types of cartridges can be used on the same equipment.

Detailed Implementation

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown: A fully automatic adjustable bore force and bore fitting test device includes a stand 1 and several bore fitting test units, which are arranged on the stand 1; specifically, the several bore fitting test units are arranged in a row on the stand 1.

[0027] Each bore inspection unit includes a bore infeed mechanism 2, an inner support rotation mechanism 3, and a flat-plate measuring mechanism 4. The flat-plate measuring mechanism 4 includes a full-form gauge 4.1 and a flat-plate measuring assembly. The bore infeed mechanism 2 and the inner support rotation mechanism 3 are located on the first port side and the second port side of the full-form gauge 4.1, respectively. The flat-plate measuring assembly is located at the first port of the full-form gauge 4.1. The bore infeed mechanism 2 includes a cartridge slide rail 2.1, a pushing assembly 2.2, and a cartridge lifting assembly 2.3. The bore infeed mechanism 2 is guided and supported by the cartridge slide rail 2.1, and the pushing assembly 2.2 feeds the cartridge into the full-form gauge 4.1. The cartridge slide rail 2.1... The push assembly 2.2 is used for loading and unloading workpieces (tubes). Its drive end is equipped with a movable claw hook to grip the bottom flange of the tube and pull it out. The tube lifting assembly 2.3 is located in front of the first port of the full-form gauge 4.1. The tube lifting assembly 2.3 can raise the opening of the tube on the tube slide rail 2.1 to align with the full-form gauge 4.1. Because the tube has a cone structure with one large end and one small end, it cannot be coaxial with the full-form gauge 4.1 when placed on the tube slide rail 2.1. Therefore, before the tube enters the full-form gauge 4.1, the small end of the tube is lifted by the tube lifting assembly 2.3. The rotating shaft 3.1 of the inner support rotating mechanism 3 extends from the second port of the full-form gauge 4.1. The rotating shaft 3.1 is coaxial with the full-form gauge 4.1, and the joint on the rotating shaft 3.1 can engage with the tube to transmit torque or disconnect contact. The outer circle of the cartridge is inspected by the full-form gauge 4.1 to check if it is qualified, and the bottom surface of the cartridge is inspected by the flat-plate assembly. However, the flat-plate assembly can only inspect 1 / 4 of the bottom surface of the cartridge each time it moves. Therefore, the inner support rotation mechanism 3 drives the cartridge to rotate 90° every time the flat-plate assembly performs an inspection.

[0028] The test bench 1 has several chamber fitting inspection units with two or more testing specifications; it enables the adaptation of different types of cartridge cases and ensures that multiple types of cartridge cases can be used on the same equipment.

[0029] The multiple chamber inspection units on the test bench 1 can also be a single inspection specification, enabling rapid batch inspection and increasing production line throughput.

[0030] The cartridge slide rail 2.1 includes two V-shaped support ramps spaced apart. The drive end of the push assembly 2.2 is located between the two support ramps, ensuring balanced force on the cartridge when the push assembly 2.2 pushes it. The cartridge slide rail 2.1 supports the cartridge via the two support ramps, automatically centering it after placement, and has a wide range of adaptability to cartridge diameters.

[0031] like Figure 4As shown: The cartridge lifting assembly 2.3 includes two clamping blocks 2.3.1, each connected to a transverse pushing element 2.3.2. The clamping ramps on the two clamping blocks 2.3.1 correspond to the two supporting ramps of the cartridge slide rail 2.1, thus connecting the cartridge lifting assembly 2.3 to the cartridge slide rail 2.1. The transverse pushing element 2.3.2 moves the two clamping blocks 2.3.1 closer together, lifting the cartridge through the supporting ramps. The transverse pushing element 2.3.2 uses a cylinder, but can also use an electric push rod or similar components.

[0032] like Figure 5 As shown: The upper part of the drive end of the pushing component 2.2 is the pushing backrest 2.2.1, and the lower part is the movable claw hook, which includes a vertical pushing element 2.2.2 and a hook body 2.2.3. When the pushing component 2.2 pushes the cartridge case towards the full-form gauge 4.1, the hook body 2.2.3 retracts. When the pushing component 2.2 pulls the cartridge case out of the full-form gauge 4.1, the vertical pushing element 2.2.2 lifts the hook body 2.2.3, which engages with the bottom flange of the cartridge case, pulling the cartridge case out. The vertical pushing element 2.2.2 uses a cylinder, but an electric push rod or similar functional components can also be used.

[0033] The drive mechanism of the push component 2.2 adopts a chain and sprocket mechanism, a cylinder or an electric push rod.

[0034] like Figure 6 As shown: The measuring latch assembly includes a measuring scale 4.2 and a torque output element 4.3. The support shaft 4.4 of the measuring scale 4.2 is mounted on the top of the first port of the full profile gauge 4.1. The torque output element 4.3 is mounted on a bracket 5 connected to the stand 1. A residual circular gear ring 4.5 coaxial with the support shaft 4.4 is connected to the measuring scale 4.2. The gear 4.6 on the torque output element 4.3 meshes with the residual circular gear ring 4.5; the transmission through the residual circular gear ring 4.5 avoids interference with the first port of the full profile gauge 4.1. The torque output element 4.3 is a motor.

[0035] The connecting part on the rotating shaft 3.1 is the inner support cylinder 3.2. When the inner support cylinder 3.2 is extended, it supports the inner wall of the cartridge, and the rotating shaft 3.1 can drive the cartridge to rotate. When the inner support cylinder 3.2 is retracted, it does not contact the cartridge. The driving part of the inner support rotating mechanism 3 adopts a motor and a reducer.

[0036] The inner support rotation mechanism 3 and the measuring flat latch mechanism 4 are covered by an outer shell 6.

[0037] Before starting, the cartridge is placed into the corresponding cartridge slide rail 2.1 by the robotic arm, and the operator clicks to start; based on the cartridge type, the cartridge lifting component 2.3 operates to lift the cartridge, and the pushing component 2.2 adjusts the propulsion force according to the cartridge type to push the cartridge into the full-form gauge 4.1. After the detection is in place, the pushing component 2.2 retracts.

[0038] The inner support cylinder 3.2 opens to fix the medicine cartridge, and the torque output element 4.3 drives the measuring ruler 4.2 to swing. After the measuring ruler 4.2 scrapes across the bottom plane of the medicine cartridge, it returns to its original position.

[0039] The push assembly 2.2 uses hook 2.2.3 to hook the cartridge and pull it out of the full-form gauge 4.1 by about 50cm. The inner support rotation mechanism 3 drives the cartridge to rotate 90° through the inner support cylinder 3.2 via the rotation shaft 3.1. Then, the push assembly 2.2 pushes the cartridge into the full-form gauge 4.1. After detection, the push assembly 2.2 retracts.

[0040] The torque output element 4.3 drives the detection ruler 4.2 to move again, and the detection ruler 4.2 returns to its original position after scraping across the bottom plane of the medicine cartridge.

[0041] Repeat this process until the entire bottom surface of the cartridge case has been inspected;

[0042] After the test is completed, the push component 2.2 uses the hook 2.2.3 to pull out the cartridge, and the robotic arm picks up the cartridge.

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.
