Abstract
The invention discloses a cylinder of a handheld nail-shooting fastening tool, which comprises an inner cylinder and an outer cylinder, wherein the inner cylinder and the outer cylinder of an aluminum profile are connected together through aluminum profile ribs integrated with the inner cylinder and the outer cylinder. The invention has the advantages of high consistency of concentricity for the inner cylinder and the outer cylinder, high qualification rate, small processing amount and good working performance.
Description
Technical Field
The invention relates to a cylinder of a hand-held nail shooting fastening tool.
Background
The nail shooting fastening tool is directly powered by a lithium battery, and the specific principle is as follows: the high-pressure gas is stored behind the striker piston, the striker piston is driven by the high-pressure gas after the switch is pressed, the striker is driven to fire and nailing, the striker piston finally collides and stops on the buffer block, and then the flywheel is driven after the motor is decelerated through the gear box, so that the striker is pulled back to the initial firing position, and the next firing is prepared.
The device for storing high-pressure gas is called a cylinder, and is generally divided into an inner cylinder and an outer cylinder, and a closed space between the outer cylinder and the inner cylinder is used for storing high-pressure gas and is called a gas chamber. The inner cylinder wall is used for a track on which the striker piston runs.
The products on the market generally separate the inner cylinder and the outer cylinder. With threaded connections or directly assembled. The disadvantages of this approach are the following:
1) The inner cylinder and the outer cylinder are complex in shape, large in processing amount and high in cost.
2) The inner cylinder and the outer cylinder are connected by screw threads or directly matched, the concentricity is not guaranteed, and the qualification rate is low.
Disclosure of Invention
The invention aims to provide a cylinder of a handheld nail shooting fastening tool, which has the advantages of high consistency of concentricity for an inner cylinder and an outer cylinder, high qualification rate, small processing amount and good working performance.
The technical scheme of the invention is as follows:
the utility model provides a hand-held type is penetrated nail fastening tool's cylinder, includes interior jar, outer jar, characterized by: the inner cylinder and the outer cylinder are connected together through a section of aluminum profile through a plurality of ribs (namely, the inner cylinder of the aluminum profile and the outer cylinder of the aluminum profile are connected together through a plurality of aluminum profile ribs which are integrated with the inner cylinder and the outer cylinder).
The sealing ring groove is arranged between the inner cylinder and the outer cylinder, and a sealed air chamber for storing high-pressure gas is formed with the inserted sealing ring.
The air chamber for storing high-pressure air is composed of an air cylinder, a rear cover, a firing pin piston, a sealing ring and respective sealing pieces, wherein the air cylinder, the rear cover, the firing pin piston and the sealing pieces are manufactured by aluminum profiles.
The front part of the air cylinder is provided with an air cylinder sealing ring groove, a sealing ring is inserted between the inner cylinder and the outer cylinder, an inner cylinder sealing ring and an outer cylinder sealing ring are respectively arranged inside and outside the sealing ring, and sealing is respectively formed with the outer wall of the inner cylinder and the inner wall of the outer cylinder;
the rear part of the cylinder and the rear cover with the sealing ring form a seal, and the inner wall of the inner cylinder and the firing pin piston form a seal through the piston sealing ring;
and (3) machining and subtracting a part of inner cylinder material at the rear part of the inner cylinder (namely, at the side close to the rear cover) to serve as a rear air chamber, so that the air chamber between the inner cylinder and the outer cylinder is communicated, and the air chamber is formed together.
The invention has the advantages of high consistency of concentricity for the inner cylinder and the outer cylinder, high qualification rate, small processing amount and good working performance.

Description of the embodiments
The utility model provides a cylinder of hand-held type nail shooting fastening instrument, has avoided the separate structure of outer cylinder and interior jar on the market, designs one section aluminium alloy (aluminium agent shaping) structure and connects the interior jar 1-2 and the outer jar 1-1 of nail shooting fastening instrument cylinder 1 together through several inside and outside jar connecting rib 1-3.
A cylinder sealing ring groove 1-4 is designed at the front part of a cylinder 1, a sealing ring 12 is inserted between an inner cylinder 1-2 and an outer cylinder 1-1, an inner cylinder sealing ring 13 and an outer cylinder sealing ring 14 are respectively arranged inside and outside the sealing ring 12, and sealing is respectively formed with the outer wall of the inner cylinder 1-2 and the inner wall of the outer cylinder 1-1.
The rear part of the cylinder 1 is sealed with the rear cover 2 with a sealing ring, and the inner wall of the inner cylinder 1-2 is sealed with the firing pin piston 9 through a piston sealing ring 10.
At the rear part of the inner cylinder 1-2 (near the rear cover 2 side), a part of the material of the inner cylinder 1-2 is removed by turning to serve as a rear air chamber 1-5. The air chamber between the inner cylinder 1-2 and the outer cylinder 1-3 is communicated to form an air chamber together.
The cylinder 1, the rear cover 2, the striker piston, the sealing ring 12 and the respective seals thus made of aluminum profiles form a gas chamber for storing high-pressure gas.
