Abstract

The utility model discloses a kind of cross slide core spherical washer components of torque wrench, including slide core and ball-type cross gasket, there are 4 uniformly distributed R slots on the periphery of slide core, there is steel ball in R slot, slide core keeps concentric with the steel tube inner hole axis of torque wrench in assembling torque spanner, wherein, ball-type cross gasket is equipped with convex cross-rib, slide core tail end is the recessed cross recess of dribbling R, slide core and spherical cross gasket are slidably connected by the recessed cross recess of convex cross-rib and slide core tail end the dribbling R of spherical cross gasket, slide core front end is equipped with recessed side, the central cross line of the recessed cross recess of central cross line and tail end the dribbling R of the recessed side in slide core front end keeps the relationship being overlapped.The utility model has the advantages that can to make that torque wrench is more stable in the operating condition, precision is higher.

Description

The cross slide core spherical washer component of torque wrench

Technical field

The utility model relates to torque wrench fields, and in particular to a kind of cross slide core spherical washer group of torque wrench Part.

Background technique

Torque wrench is a kind of common installation and removal tool, by lever principle twist bolt, nut and its His screw thread tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Slide core in torque wrench is an important power Transferring element, although theoretically it can carry out 360 ° of rotations in pipe, under working condition, slide core is only allowed in 90 ° both direction in the range of swing.

Refering to Figure 1, being a kind of structural schematic diagram of existing torque wrench, which is equipped with top slide core Square, tail end be equipped with spherical washer.For the torque wrench of this structure, when pushing up the square swing of slide core, slide core is fast Speed is caudad slided, and since gasket is spherical shape, which can cause slide core axis and steel pipe axis not parallel with rotation, and Part after the error to be further transferred to gasket.

Summary of the invention

The purpose of this utility model is to solve the problems, such as existing torque wrench structure, provide a kind of the operation is stable, The cross slide core spherical washer component with high accuracy for turning round torque wrench.The purpose is achieved through the following technical solutions:

The cross slide core spherical washer component of torque wrench, including slide core and spherical cross gasket, the periphery of slide core have 4 Uniformly distributed R slot has steel ball in R slot, and slide core keeps concentric with the steel tube inner hole axis of torque wrench in assembling torque spanner, In, spherical cross gasket is equipped with convex cross-rib, and slide core tail end is the recessed cross recess of dribbling R, and slide core and spherical cross gasket pass through The recessed cross recess of convex cross-rib and slide core tail end the dribbling R of spherical cross gasket are slidably connected, and slide core front end is equipped with recessed side, slide core The central cross line of the recessed cross recess of central cross line and tail end the dribbling R of the recessed side in front end keeps the relationship being overlapped.

The utility model has the beneficial effects that: both having remained biography using mutually matched slide core and spherical cross gasket In torque wrench structure of uniting the characteristics of spherical washer, and slide core is constrained, does not allow it to rotate, so that torque wrench is in working condition Under it is more stable, precision is higher.

Wherein, 1 is spherical washer, and 2 be recessed side, and 3 be the recessed cross recess of dribbling R, and 4 be convex cross-rib, and 5 be square, and 6 be cunning Core, 7 be spherical cross gasket, and 8 be steel pipe.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.It should be noted that making in being described below Word " front end ", " tail end " refer to the direction of torque wrench in actual use.

Fig. 2 is the main view of slide core front end, and there are 4 uniformly distributed R slots on the periphery of slide core, have steel ball in R slot, slide core front end is set There is recessed side 2.Fig. 3 is the main view of slide core tail end, and slide core tail end is the recessed cross recess 3 of dribbling R.Fig. 4, Fig. 5 are respectively spherical shape ten The main view and sectional view of word gasket, spherical cross gasket are equipped with convex cross-rib 4.

Fig. 6 be the utility model be applied to torque wrench assembling figure diagrammatic cross-section, torque wrench have square 5, Slide core 6, spherical cross gasket 7, steel pipe 8, the axially bored line holding in assembling torque spanner and in the steel pipe 8 of torque wrench of slide core 6 With one heart, the recessed cross that slide core 6 and spherical cross gasket 7 pass through convex cross-rib 4 and slide core tail end the dribbling R of spherical cross gasket 7 Slot 3 is slidably connected, and the central cross line of the recessed cross recess of central cross line and tail end the dribbling R of the recessed side 2 in 6 front end of slide core is kept The relationship of coincidence.

Fig. 7 is the working state figure that the utility model is applied to torque wrench, when the recessed side 6 in slide core front end is by square 5 When extruding, slide core 6 is caudad swung along the axis of steel pipe 8, and the spherical cross gasket 7 being slidably matched with slide core 6 constrains slide core The freedom degree of movement, does not allow it to rotate, so that slide core remains pass parallel with the axis of steel pipe 8 during the motion System reduces operating error.
