A right fuel channel (5.1) of the manifold block has an L shape. A left end cap fuel channel (3.1) has an approximate C-shape, and an upper fuel port thereof is positioned at a right side surface (3.5) of a left end cap (3). A right end cap fuel channel is symmetric with the left end cap fuel channel (3.1). A horizontal hard fuel tube (9) is provided between an upper fuel port of an end cap fuel channel and a side fuel port of a fuel channel of the manifold block on the same side thereas. The horizontal hard fuel tube (9) is attached at an upper portion of the horizontal cylinder casing (2) on the same side thereas.

Description

Integrated rotary cylinder

Technical field

The invention relates to a rotary cylinder.

Background technique

The existing rotary cylinder includes (see FIG. 1), the horizontal cylinder 2 passes through the cylinder 8 and is integrated into one body. The left and right ends of the cylinder have an end cover 3, and the left end cover oil passage is an L-shaped oil passage 3.1. The upper oil port 3.2 is located at the upper end surface 3.3 of the end cover, the lower oil port 3.4 is connected to the same side cylinder cavity 2.1, and the two end cap oil passages are symmetrical; it further comprises an oil block 5 and two left and right external oil pipes 4, The oil road block has two oil passages 5.1 on the left and right sides. Each oil passage is I-shaped, and each oil passage of the oil passage block, the external oil pipe on the same side, the oil port on the end cover and the L-shaped oil passage are connected in series. The positive hydraulic oil enters the external oil pipe on the same side, the L-shaped oil passage and the cylinder cavity of the end cover through the oil passage on the left side of the oil passage block, and pushes the left piston 1 and the rack 6 to the right, and the gear 7 rotates clockwise. At the same time, the right piston moves to the right, and the hydraulic oil in the right cylinder cavity is squeezed out, and then returns to the oil source from the right end cover passage, the external oil pipe and the right oil passage of the oil block; vice versa, The drive gear reciprocates at 0-120°. It can be seen that the current reciprocating rotary cylinder is not fully integrated, and the external oil pipe is easily bumped and damaged, resulting in oil leakage.

Summary of the invention

In order to solve the above technical problems, an object of the present invention is to provide a fully integrated reciprocating rotary cylinder.

The object of the present invention is achieved as follows: it comprises an oil block and two left and right oil passages, the horizontal cylinder passes through the cylinder and is integrated into one body, the left and right end caps and their end cap oil passages, and the end cap oil The road includes an oiling port, and the oil passage block is located above the horizontal cylinder tube and integrated with the cylinder body. The left and right oil passages of the oil road block are in the shape of the right oil passage of the oil road block. L-shaped, that is, from the upper oil port first downward and then to the right to the right end surface of the upper cylinder body, forming an oil passage block side oil port, the left road oil passage and the right road oil passage are symmetrical; the end cover oil passage is The left end cover oil passage is in the shape of a dome, the upper oil port is located on the right side surface of the left end cover, the right end cover oil passage is symmetrical with the left end cover oil passage; on the same side end cover oil passage upper oil passage and oil passage block oil passage side oil port A horizontal hard oil pipe is arranged between the end cover oil passage and the oil passage block oil passage, and the horizontal hard oil pipe is attached to the horizontal cylinder tube on the same side.

The working process is that the positive hydraulic oil enters the horizontal hard oil pipe, the end cover oil passage and the cylinder cavity on the same side through the oil passage on the left side of the oil passage block, and pushes the left piston and the rack to the right, and the gear is clockwise. Rotating; at the same time, the right piston moves to the right, the hydraulic oil in the right cylinder cavity is squeezed out, and the oil is returned from the right end cap oil passage, the horizontal hard oil pipe, and the oil block right oil passage. The source and vice versa, the drive gear rotates counterclockwise to achieve reciprocal rotation of the gear.

Compared with the prior art, the positive effect of the present invention is that since the horizontal hard oil pipe is attached to the horizontal cylinder on the same side, the height of the horizontal hard oil pipe must be lower than the height of the oil block and the end cover. The horizontal hard oil pipe is embedded under the oil block and the end cover to protect the horizontal hard oil pipe from being bumped by other objects, which significantly reduces the failure rate of the equipment. Secondly, the oil block is integrated with the cylinder block (cancel The part of the cylinder above the cylinder tube realizes the complete integration of the equipment, reduces the leakage point, and is easy to install and transport, and significantly improves efficiency and reliability.

Detailed ways

Referring to Fig. 2, it comprises an oil block 5 and its left and right oil passages. The horizontal cylinder 2 passes through the cylinder 8 and is integrated into one body. The left and right end caps 3 and their end cap oil passages, the end cap oil passage The oil passage block 5 is located above the horizontal cylinder tube and integrated with the cylinder block. The left and right oil passages of the oil passage block are L-shaped in the right oil passage 5.1 of the oil passage block. That is, from the upper oil port first downwards and then to the right to the right end surface 5.2 of the upper cylinder body, the oil passage block side oil port is formed, and the left road oil passage is symmetric with the right road oil passage; the end cover oil passage is the left end cover The oil passage 3.1 has a 匚 shape, and the upper oil port is located at the right side surface 3.5 of the left end cover. The 端-shaped end cover oil passage is formed by sealing the original oil supply port with the wire plug 10 from the right side of the left end cover. Face 3.5 opens the horizontal channel to the left to the left end cap oil passage below the plug 10 to form a dome-shaped end cap oil passage. The right end cap oil passage is symmetrical with the left end cap oil passage; a horizontal hard oil pipe is arranged between the oil port on the left end cap oil passage and the oil port side oil passage block, and the hard oil pipe 9 is taken as an example on the left side. The two ends are inserted into the oil port on the left end cap oil passage and the side oil port on the left oil passage of the oil block block, and the end cover oil passage on the same side is connected with the oil passage block oil passage, and the horizontal hard oil pipe is attached on the same side. Above the horizontal cylinder.
