Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-15 This utility model provides a technical solution: an automatic electrode tube changing device for electric spark drilling, including a main shaft lifting mechanism 1, a copper tube dispensing mechanism 2 on the left side of the main shaft lifting mechanism 1, a copper tube roller feeding mechanism 8 at the bottom of the copper tube dispensing mechanism 2, a water injection sealing mechanism 6 at the bottom of the copper tube roller feeding mechanism 8, a copper tube rotating mechanism 3 at the bottom of the water injection sealing mechanism 6, a copper tube locking mechanism 4 at the bottom of the copper tube rotating mechanism 3, a copper tube clamping mechanism 5 at the bottom of the copper tube locking mechanism 4, and a translational waste collection mechanism 7 on the right side of the main shaft lifting mechanism 1.

[0036] The copper tube dispensing mechanism 2 includes a copper tube hopper 203. A long groove is formed on the side of the main shaft lifting mechanism 1. The copper tube hopper 203 is movably connected to the long groove. A hopper fixing seat 202 is fixedly connected to the front of the copper tube hopper 203.

A copper tube dispensing dipping block 206 is fixedly connected to the bottom of the copper tube hopper 203. Because the copper tube hopper 203 is inclined, and the opening on the copper tube dispensing dipping block 206 is also inclined, the material is propelled by the copper tube dispensing cylinder 201 and then falls through the dipping dipping block 206.

[0037] The copper tube rotating mechanism 3 includes a shaft bearing mounting seat B303. A guide rod cylinder mounting seat 304 is located on the left side of the shaft bearing mounting seat B303.

A rotary lifting sliding bearing 305 is movably connected to the bottom of the cylinder connecting plate 301. A steel tube rotating shaft 302 is movably connected to the rotary lifting sliding bearing 305. The left side of the shaft bearing mounting seat B303 is fixedly connected to the guide rod cylinder mounting seat 304. The copper tube locking mechanism 4 includes a locking nozzle lifting sleeve 406, which is movably sleeved on the steel tube rotating shaft 302. 2.

[0038] The mechanism has a pipe in the middle for placing copper pipes. The locking spring seat 404 is used for vertical movement, and the retracting spring 409 is used for horizontal movement. When locked, both the locking spring seat 404 and the retracting spring 409 are in a compressed state, and the pipe is locked. When unlocked, the guide rod cylinder 306 works to drive the lower part to move downward. At this time, the locking spring seat 404 is in a stretched state, and the retracting spring 409, when located outside the lifting sleeve, will rebound and push out the locking clamp block 408, so that the pipe is unobstructed.

A protective sleeve bracket L506 is provided on the front side of the stroke gripper cylinder copper tube support and pulling mechanism 504. A protective sleeve bracket R508 is provided on the front side of the long stroke gripper cylinder copper tube support and pulling mechanism 504 located on the left side.

A copper tube clamp cylinder 503 is provided below the protective sleeve bracket R508, and two copper tube clamps 502 are connected to the right side of the copper tube clamp cylinder 503.

[0040] When in use, the copper tube is first clamped in the guide sleeve 501 of the electrode protection tube support. After the first copper tube detection sensor 505 detects the presence of the copper tube, the copper tube clamp 502 will pull the material. The support and pulling mechanism of this technical solution completes the support and pulling of the copper tube through the cooperation of the sleeve, sensor and clamp, realizing complete automation. Automated transportation is achieved by setting up a support and pulling mechanism.

The sealing plug and sealing ring 606 is used for perimeter waterproofing to prevent water from leaving from the perimeter gaps of the water-stop plug body. The top plate sealing ring 605 is used for top waterproofing. At the same time, due to the setting of the installation groove structure, the top plate sealing ring 605 is not easy to fall off when the top plate moves, and will not affect the waterproofing requirements.

The copper tube conveying wheel 2 is opened by rotating the pressure wheel bearing fixing seat 3, thereby realizing the adjustment of the copper tube conveying wheel 2.

[0045] A belt has been added to prevent gear collisions or poor engagement of the power mechanism gears when transporting copper tubes of different diameters for replacement and adjustment. The clamping range has been expanded from 0-0.8mm to 0-3mm.
