The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a two exchange device of horizontal revolving stage for machining center workstation position exchanges, has the base, base below be equipped with the unclamping cylinder, the base upper end is equipped with liftable and rotatory roating seat for the bracket that drags the workstation to exchange can install in the roating seat up end, unclamping cylinder piston rod stretch into in the base and the tailpiece of the piston rod portion installs the bearing, the roating seat has the intracavity boss, intracavity boss below is equipped with the gear, and the bearing inner race is concentric fixed with the hole and the gear hole of intracavity boss respectively, is fixed with on the base outer wall and drives actuating cylinder, drives to be fixed with on the actuating cylinder piston rod with the driven rack of gear engagement.
Preferably, in order to increase the exchange speed of the workbench, two sides of the outer wall of the base are respectively fixed with a driving cylinder, and a piston rod of the driving cylinder is correspondingly and fixedly connected with two ends of the rack.
Furthermore, a guide ring is arranged between the periphery of the upper end of the base and the inner hole of the rotating seat.
The utility model has the advantages that: the power source of the utility model adopts pneumatic drive, compared with the traditional hydraulic drive mode, the air source drive is matched with the rack and pinion mechanism, the rotating torsion is large, and the action response of the rotating seat is rapid; the knife striking cylinder is selected to realize the lifting of the rotating seat, the bearing capacity is strong, the structure can be simplified, and the installation and the maintenance are convenient.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic top view of the structure of fig. 1.
Fig. 3 is a schematic diagram of the three-dimensional structure of the present invention.
In the figure: 1. the device comprises a base, 2 parts of a unclamping cylinder, 3 parts of a rotating seat, 3-1 parts of an intracavity boss, 4 parts of a bearing, 5 parts of a gear, 6 parts of a driving cylinder, 7 parts of a rack, 8 parts of a guide ring and 9 parts of a gland.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The double-exchange device for the horizontal rotary table is used for exchanging the position of a workbench of a machining center and comprises a base 1, wherein the outer wall of the upper end of the base 1 is provided with steps, the bottom surface of the base 1 is fixedly connected with a unclamping cylinder 2, the upper end of the base 1 is provided with a rotary seat 3 which can be lifted and rotated, the rotary seat 3 is provided with an intracavity boss 3-1, the upper end surface of an inner hole of the intracavity boss 3-1 is fixedly connected with a gland 9 which has a sealing effect, and a bracket for dragging the exchange of the workbench can be arranged on the upper end surface of the rotary seat 3.
The piston rod of the unclamping cylinder 2 extends into the base 1, the end part of the piston rod of the unclamping cylinder 2 is fixedly connected with a bearing 4, a gear 5 is arranged below the boss 3-1 in the cavity, and the outer ring of the bearing 4 is concentrically fixed with the inner hole of the boss 3-1 in the cavity and the inner hole of the gear 5 respectively.
The two sides of the outer wall of the base 1 are respectively fixed with a driving cylinder 6, a rack 7 which is meshed with the gear 5 for transmission is fixed between piston rods of the two driving cylinders 6, and the thickness of the gear 5 is required to meet the condition that the gear 5 and the rack 7 are always in a meshed state when the rotary seat 3 goes up and down.
And an L-shaped guide ring 8 is arranged between the step of the outer wall at the upper end of the base 1 and the inner hole of the rotating seat 3.
When the working tables are exchanged, the air supply of the unclamping cylinder 2 acts, the piston rod of the unclamping cylinder 2 rises to jack up the rotary base 3 through the bearing 4, when the rotary base 3 rises to the right position, the unclamping cylinder 2 stops acting, the air supply of the driving cylinder 6 is driven, one of the driving cylinder 6 extends out, the piston rod of the driving cylinder 6 returns, the rack 7 is pushed by the combined action of the driving cylinders 6 to move, the rack 7 moves to be meshed with the transmission gear 5 to rotate, the rotary base 3 is driven to rotate, and the exchange of the working tables on two sides of the rotary base 3 is realized. When the work bench is exchanged again, the two driving cylinders 6 act in opposite directions to complete the one-time reciprocating exchange process of the work bench.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
