Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 6, a torque gun with a quick-change structure of a screwdriver bit of the present invention includes a power screwdriver 10 and a plurality of bit bases 12. The batch header 12 may be disposed on a mating batch header station 14.

The front part of the screwdriver head seat 12 is provided with a screwdriver head 16, the rear part of the screwdriver head seat 12 is provided with a connecting hole 18, and the electric screwdriver 10 comprises a driving rod 20 which can extend into the connecting hole 18 and a motor 11 which drives the driving rod 20 to rotate. The cross section of the connecting hole 18 is polygonal, and the cross section of the driving rod 20 is polygonal matched with the shape of the connecting hole 18.

The driving rod 20 is driven to rotate by the motor, so that the batch head seat 12 is driven to rotate by the driving rod 20, and the batch head is rotated to work.

In order to realize that the driving rod 20 can be quickly connected and detached with the bit head seat 12, the utility model adopts the following structure:

an annular groove 22 is arranged on the outer wall of the driving rod 20, and the cross section of the annular groove 22 is semicircular; the screwdriver head seat 12 is provided with a plurality of pin holes 24 communicated with the connecting holes 18, and a fixing pin 26 is arranged in each pin hole 24; an annular pressing ring 28 is sleeved outside the batch head seat 12, and an annular accommodating groove 30 for accommodating the fixing pin 26 is arranged on the inner wall of the pressing ring 28; a spring 32 is disposed between the batch head seat 12 and the press ring 28.

Furthermore, a plurality of elongated limiting holes 34 are formed in the side wall of the pressing ring 28, and a limiting screw 36 which is connected to the screwdriver head seat 12 in a threaded manner is disposed in each limiting hole 34. The stop screw 36 acts to stop the press ring 28 so that it can move axially but cannot disengage from the seat 12.

Furthermore, a first retainer ring 38 protruding out of the outer wall of the press ring 28 is arranged outside the press ring, and a second retainer ring 40 protruding out of the outer wall of the screwdriver head seat 12 is arranged outside the screwdriver head seat; the spring 32 is sleeved outside the pressing ring 28, and two ends of the spring respectively abut against the first retaining ring 38 and the second retaining ring 40 so as to drive the pressing ring 28 to move away from the electric screwdriver 10. A protective ring 33 is sleeved outside the spring 32.

Further, a plurality of longitudinal slots 42 are disposed on the outer side of the batch head seat 12 along the length direction of the batch head, and are used for matching with the batch head table 14 to prevent the batch head seat 12 from rotating.

Further, the fixing pin 26 has a cylindrical structure with both ends thereof being hemispherical.

The utility model also provides a torque gun kit with a batch head quick-change structure, which further comprises a batch head table 14 matched with the torque gun.

The batch head table 14 is provided with a batch head groove 44 for accommodating the batch head seat 12, a press block hole (not shown) communicated with the batch head groove 44 is arranged on the side wall of the batch head table 14, a press block 46 is movably arranged in the press block hole, and a driving device 48 for driving the press block 46 to move so as to press the batch head seat 12 on the batch head table 14 is arranged on one side of the batch head table 14. The drive means is typically a cylinder or an electric motor.

The inner side wall of the batch head groove 44 is provided with a spring pin 50 for limiting the rotation of the batch head seat 12.

The working principle of the above-mentioned structure is that,

when in connection: the accommodating groove 30 and the fixing pin 26 are in an aligned state, and after the driving rod 20 is inserted into the connecting hole 18 by the manipulator; the spring 32 is loosened, under the action of the elastic force of the spring 32, the pressing ring 28 extrudes the fixing pin 26 accommodated in the accommodating groove 30, so that the accommodating groove 30 and the fixing pin 26 are dislocated, one end of the extruded fixing pin 26 enters the annular groove 22 of the driving rod 20, and the driving rod 20 is limited, so that the driving rod 20 cannot be withdrawn outwards, and the connection between the driving rod 20 and the batch head seat 12 is realized; to facilitate the movement of the fixing pin 26, the receiving groove 30 may be formed as a slope or a curved surface.

When the disassembly is carried out: the torque gun is driven by the manipulator to downwards extrude the press ring 28, so that the fixing pin 26 is aligned with the accommodating groove 30; at this time, the pressing block of the batch head table 14 is pressed on the step part 52 of the batch head table 12, so that the spring 32 cannot be reset; therefore, when the driving rod 20 is withdrawn outwards, the fixing pin 26 can be withdrawn into the accommodating groove 30, so that the withdrawal of the driving rod 20 is prevented from being blocked, and the quick detachment is realized.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
