Summary of the invention
The purpose of this utility model is to design a kind of workbench and clamps checkout gear, and decidable table positions situation is for the positioning accuracy of pallet changer provides better assurance.
For achieving the above object, the technical solution of the utility model is:
A kind of workbench clamps checkout gear, and it comprises, base is established intermediate on it; Drawing cylinder is arranged on the intermediate, comprises cylinder body and piston; Workbench, its lower surface is offered the groove of a corresponding drawing cylinder; Supporter is connected on the described drawing cylinder piston, and supporter inserts workbench lower surface groove; Gripper shoe, be connected in the lower surface of described workbench groove notch both sides, gripper shoe one end protrudes in the workbench groove notch, withheld by the supporter on the interior drawing cylinder piston of workbench groove, and workbench is subjected to the supporter pulling on the drawing cylinder piston to realize tension by gripper shoe; At least two locating pieces are arranged at the drawing cylinder both sides respectively, are connected on the intermediate, the gripper shoe of corresponding workbench groove notch both sides lower surface; Two locating pieces are offered the purging through hole vertically, and outlet is positioned at the locating piece upper surface; Wherein a positioning block is also offered a gas vertically and is detected through hole, and its outlet also is positioned at this locating piece upper surface; Described purging through hole and gas detect through hole and are communicated with external source of the gas by gas piping respectively; Baroceptor is arranged in the gas piping that is communicated in locating piece gas detection through hole.
Drawing cylinder comprises cylinder body and piston, and inboard wall of cylinder block is offered groove, and the groove top and bottom sidewall is established oil cylinder tension oil-in, oil cylinder rising oil-in respectively, and these two oil-ins are in communication with the outside by pipeline respectively; Piston side wall is inserted in the inboard wall of cylinder block groove respectively along circumferentially establishing projection, and projection moves up and down along groove.
In workbench bottom gripper shoe is installed, drawing cylinder is installed on the intermediate, and a plurality of locating pieces are installed on intermediate, and locating piece all has the air blowing structure, can know dust on the locating surface and tiny iron filings in the process of tension workbench.
The locating piece that has gas inspection structure is arranged in four angles and middle part at workbench, be used for realizing the position probing after the workbench tension, oil cylinder is realized the clamping of workbench on locating piece by the tension gripper shoe, utilize gas inspection locating piece to come the testing platform to clamp the accuracy of its position, back, thereby realize the clamping and the measuring ability of large-scale workbench.
Advantage of the present utility model is:
1, realize workbench fixing on locating piece by the gripper shoe on the oil cylinder tension workbench, whole take-up device is below workbench, and is simple in structure.
2, by increasing a gas verify structure on the locating piece and in gas return path, increasing a baroceptor, realize the position probing after workbench clamps.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structural representation of locating piece among the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 3, a kind of workbench of the utility model clamps checkout gear, and it comprises that base 1 is established intermediate 2 on it; Drawing cylinder 3, be arranged on the intermediate 2, comprise cylinder body 31 and piston 32, cylinder body 31 inwalls are offered groove 311, and (with a side groove is example, down together), the groove top and bottom sidewall is established oil cylinder tension oil-in 312, oil cylinder rising oil-in 313 respectively, and these two oil-ins are in communication with the outside by pipeline respectively; Piston 32 sidewalls are inserted in inboard wall of cylinder block groove 311 respectively along circumferentially establishing projection 321, and projection 321 moves up and down along groove 311.
Gripper shoe 6, be connected in the lower surface of described workbench 4 grooves 41 notch both sides, gripper shoe 6 one ends protrude in workbench groove 41 notches, withheld by the supporter 5 on workbench groove 41 interior drawing cylinder 3 pistons, workbench 4 is subjected to supporter 5 pullings on drawing cylinder 3 pistons to realize tension by gripper shoe 6.
Two locating pieces 7,8 are arranged at drawing cylinder 3 both sides respectively, are connected on the intermediate 2, the gripper shoe 6 of corresponding workbench 4 grooves 41 notch both sides lower surfaces; Two locating pieces 7,8 are offered vertically and are purged through hole 71 (is example with locating piece 7), and outlet is positioned at locating piece 7 upper surfaces; Wherein a positioning block 7 is also offered a gas vertically and is detected through hole 72, and its outlet also is positioned at this locating piece 7 upper surfaces; Described purging through hole and gas detect through hole and are communicated with external source of the gas by gas piping respectively; Baroceptor 9 is arranged in the gas piping that is communicated in locating piece gas detection through hole 72.
By the oil-in oil-feed that is fixed on drawing cylinder on the intermediate oil cylinder piston is descended, make the supporter that links to each other with the drawing cylinder piston body along with piston moves down, the gripper shoe that supporter is withheld below workbench makes workbench along with piston descends together, combines closely until gripper shoe and locating piece.
In the process that piston at drawing cylinder descends, strains, the through hole ventilation is surveyed in gentle health check-up to the purging through hole of two locating pieces, purge, remove the fine impurity on the locating piece, and gas detects through hole after gas enters, along with moving down of workbench, gripper shoe and the distance between the locating piece under it are more and more littler, and can cause increase this moment to the air pressure in the gas return path that enters gas detection through hole.Air pressure reaches maximum when gripper shoe and locating piece are combined closely, at this moment there is the baroceptor that is installed on the gas inspection pipeline to detect the atmospheric pressure value in the gas return path after workbench is strained, if atmospheric pressure value reaches the pressure that sets in advance, illustrate that workbench and locating piece location is good, thereby provide good assurance for the precision after the workbench tension.
