Summary of the invention
The purpose of this utility model is in order to overcome the easy transfer of gear shaft while tightening air pressure pump gear, to need two shortcomings that people operates, a kind of air pressure pump gear tightening tool with counter-force bar is provided, only need one man operation to tighten, can increase work efficiency simultaneously.
The technical solution adopted in the utility model is as follows: a kind of air pressure pump gear tightening tool with counter-force bar, comprises electric wrench, train wheel bridge, lower plate, spanner connecting plate, counter-force bar, counter-force gear, oilless bearing and Pneumatic sleeve; Described electric wrench is connected with counter-force bar by train wheel bridge, lower plate and spanner connecting plate, described train wheel bridge and lower plate lay respectively at the both sides up and down of electric wrench, described train wheel bridge and lower plate are fixed electric wrench by the second hexagon socket cap head screw, and lower plate is fixed on spanner connecting plate by the 4th hexagon socket cap head screw; Described counter-force bar is located and is fixed on described spanner connecting plate by the 3rd hexagon socket cap head screw by the second straight pin, one end of counter-force bar is fixed with counter-force gear by straight pin and hexagon socket cap head screw, in counter-force bar and spanner connecting plate, be provided with oilless bearing, the outer wall of described oilless bearing coordinates with counter-force bar and spanner connecting plate, and described Pneumatic sleeve is arranged in oilless bearing and with the rotating shaft of electric wrench and is connected.
Further, endoporus size and the Pneumatic sleeve of described oilless bearing match, oilless bearing and Pneumatic sleeve matched in clearance.
Further, the specification of described Pneumatic sleeve and air pressure pump gear clamp nut match.
Further, the installation site of described counter-force gear and air pressure pump gear correct engagement, the gear parameter of counter-force gear and air pressure pump gear match, and the number of teeth of described counter-force gear should meet the safety requirements of air pressure pump gear screw-down torque, at least arranges 2.
The utility model is simple and compact for structure, reasonable in design, easy to use, be convenient to one man operation, by being set, counter-force bar solved the problem of gear shaft transfer while tightening air pressure pump gear, counter-force gear location is fast and reliable, with the engagement of air pressure pump gear, in use avoid colliding with, locate and tighten simultaneously and carry out, simplified and tightened flow process, improved operating efficiency.
figure of description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic cross-section of the present utility model.
Accompanying drawing explanation: counter-force gear 1, the first straight pin 2, the first hexagon socket cap head screw 3, spanner connecting plate 4, the second straight pin 5, electric wrench 6, the second hexagon socket cap head screw 7, train wheel bridge 8, lower plate 9, oilless bearing 10, the 3rd hexagon socket cap head screw 11, counter-force bar 12, Pneumatic sleeve 13, the 4th hexagon socket cap head screw 14.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-Figure 2, a kind of air pressure pump gear tightening tool with counter-force bar, comprises electric wrench 6, train wheel bridge 8, lower plate 9, spanner connecting plate 4, counter-force bar 12, counter-force gear 1, oilless bearing 10 and Pneumatic sleeve 13; Electric wrench 6 is connected with counter-force bar 12 by train wheel bridge 8, lower plate 9 and spanner connecting plate 4, train wheel bridge 8 and lower plate 9 lay respectively at the both sides up and down of electric wrench 6, train wheel bridge 8 and lower plate 9 are fixing by electric wrench 6 by the second hexagon socket cap head screw 7, and lower plate 9 is fixed on spanner connecting plate 4 by the 4th hexagon socket cap head screw 14; On spanner connecting plate 4, be connected with counter-force bar 12, counter-force bar 12 is located by the second straight pin 5 with spanner connecting plate 4 and is passed through the 3rd hexagon socket cap head screw 11 and fix; One end of counter-force bar 12 is installed with counter-force gear 1 by the first straight pin 2 and the first hexagon socket cap head screw 3, the gear parameter of counter-force gear 1 and air pressure pump gear match, should there is identical pressure angle and modulus, can avoid so in use because excesssive gap causes tightening, occurring clashing into; Mesh completely with air pressure pump gear just the installation site of counter-force gear 1, and after counter-force gear 1 assemble, its basic circle position and air pressure pump rolling circle position consistency, avoid that use procedure intermediate gap is excessive causes tightening appearance shock; The number of teeth of described counter-force gear 1 is 5, can increase the contact area with air pressure pump gear, reduces contact; In counter-force bar 12 and spanner connecting plate 4, be provided with oilless bearing 10, described Pneumatic sleeve 13 is arranged in oilless bearing 10 and with the rotating shaft of electric wrench 6 and is connected, the outer wall of oilless bearing 10 coordinates with counter-force bar 12 and spanner connecting plate 4, endoporus size and the Pneumatic sleeve 13 of oilless bearing 10 match, Pneumatic sleeve 13 and oilless bearing 10 matched in clearance, change convenience, do not affect Pneumatic sleeve 13 rotations and have guide effect, the specification of Pneumatic sleeve 13 is chosen according to the difference of air pressure pump gear clamp nut.
