Abstract

The utility model discloses a gear ring connection device for a heavy vertical lathe bench, wherein the device comprises an upper connection plate, a left half gear ring, screws, tapered cotters, a lower connection plate and a right half gear ring, wherein two fixing slots are respectively arranged at the upper end of the left half gear ring and the lower end of the right half gear ring, the upper connection plate and the lower connection plate are respectively arranged in the upper and lower fixing slots, and the screws and the tapered cotters are staggered between the upper connection plate and the lower connection plate to connect and locate the upper connection plate and the lower connection plate. The gear ring connection device has the beneficial effects that the device well solves the problem the connection rigidity of the two half gear rings of the vertical lathe bench is low and the locating precision is low, and due to the staggered use of the screws and the tapered cotters, the connection rigidity and the connection precision are more stable.

Description

Heavy vertical lathe workstation gear ring coupling arrangement

Technical field

The utility model relates to a kind of heavy vertical lathe workstation gear ring coupling arrangement, belongs to the Machining Technology field.

The gear ring intended diameter of present many heavy vertical lathe workstations is all more than 6 meters, and due to the restriction that is subjected to the transportation aspect, gear ring generally all adopts minute half to arrange, the large mostly employing bolt docking of connecting mode between two half-ring gears.Because the joint stiffness of bolt is limited, in gear ring and worktable installation process, the gap often appears in the gear ring joint, tends to gear ring is impacted with the precision that connects between worktable.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of heavy vertical lathe workstation gear ring coupling arrangement, and this device has very strong joint stiffness, thereby guarantees the precision that connects of gear ring and worktable.

The technical solution of the utility model is: this device is made of first line of a couplet fishplate bar, left half-ring gear, screw, taper pin, second line of a couplet fishplate bar and right half-ring gear; Top and bottom at left half-ring gear and right half-ring gear are respectively equipped with fixed groove, in upper and lower two fixed grooves, first line of a couplet fishplate bar and second line of a couplet fishplate bar are housed respectively; Between first line of a couplet fishplate bar and second line of a couplet fishplate bar, the staggered screw that uses is connected the location with taper pin.

The beneficial effects of the utility model are: two half-ring gear joint stiffnesses that this device has solved vertical lathe workstation well are low, the problem that Location accuracy is low, and the staggered use of screw and taper pin makes joint stiffness and connects precision more stable.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Fig. 1 is structural representation of the present utility model.

Number in the figure:

1, first line of a couplet fishplate bar 2, left half-ring gear 3, screw 4, taper pin
