Detailed Description
The invention will be further explained with reference to the drawings.
The embodiment of the invention provides a hydraulic wrench, which comprises a main body 1, wherein a sleeve component 2 is arranged on an output shaft 11 at one end of the main body 1, a supporting component 3 is arranged at the other end of the main body 1, the sleeve component 2 comprises a detachable sleeve lining 21, and the supporting component 3 comprises a fixed shaft 31 fixedly connected with the main body 1 and a supporting seat 32 with one end sleeved on the fixed shaft 31; the support base 32 can rotate about the axis of the fixed shaft 31 to adjust the supporting direction.
Specifically, as shown in fig. 1, one end of the hydraulic wrench is a sleeve assembly 2 for disassembling and assembling the fastener, the sleeve assembly 2 is connected to an output shaft 11 at one end of the main body 1, and the output shaft 11 can drive the sleeve assembly 2 to rotate, so as to rotate the fastener with disassembly and assembly. The detachable sleeve liner 21 in the sleeve assembly 2 is mainly used for matching the fastener to be disassembled and assembled, and is provided with a wrench clamping groove 211 for matching the fastener to be disassembled and assembled, so that when fasteners with different sizes are handled, only the corresponding sleeve liner 21 needs to be replaced. Different sleeve liners 21 have the same overall dimensions to fit the same hydraulic wrench, but different sleeve liners 21 have different sized wrench slots 211 to fit different sized fasteners.
In addition, because the hydraulic wrench is usually used for dismounting and mounting a large torque, the rest part needs to be kept static and stable, and the fingers of an operator are easily pinched or bruised by the reaction of the torque when the operator is held and fixed by hands, the other end of the main body 1 is provided with the supporting component 3 for forming a certain stressed structure between the hydraulic wrench and an external fixed structure so as to balance the counter torque and avoid the possibility of injuring the hands of the operator. The supporting seat 32 of the supporting assembly 3 is a structure extending outward along the radial direction of the fixed shaft 31 as shown in fig. 1, and can rotate relative to the fixed shaft 31 to adjust the angle, so as to adjust the supporting direction of the supporting seat 32. For example, if the fastener has a stable support surface (e.g., ground) below it in the operating environment, the support base 32 can be rotated to correspond to and support the underside of the liquid wrench, thereby balancing the torque reaction of the wrench; similarly, if the side of the fastener in its operating environment has a stable support surface (e.g., wall surface, equipment frame), the support base 32 can also be rotated to the corresponding side.
In one embodiment, the support assembly 3 further includes a sleeve body 22, the sleeve body 22 is fixedly connected to the output shaft 11, and the sleeve liner 21 is detachably inserted into the insertion groove 221 of the sleeve body 22 with the positioning structure 4 therebetween.
Specifically, as shown in fig. 1 and 2, the socket body 22 is fixedly connected to the output shaft 11 of the wrench, and has a caulking groove 221 for accommodating the socket liner 21, and the external size of the socket liner 21 matches the internal size of the caulking groove 221. For fasteners of different sizes, only the corresponding sleeve liner 21 needs to be replaced and installed into the caulking groove 221. The caulking groove 221 and the sleeve liner 21 are relatively fixed through the positioning structure 4.
In one embodiment, the positioning structure 4 includes a plurality of positioning grooves 41 formed on a first end surface of the sleeve liner 21 and a plurality of positioning pillars 42 formed on a bottom of the insertion groove 221, wherein the first end surface is attached to the bottom of the insertion groove 221 when the sleeve liner 21 is inserted into the insertion groove 221.
Specifically, the positioning structure 4 mainly serves to keep the sleeve liner 21 and the sleeve body 22 relatively fixed in the circumferential direction of the output shaft 11, i.e., to keep the sleeve liner 21 and the sleeve body 22 rotatable in synchronization. As shown in fig. 2, the positioning structure 4 adopts a structure in which the positioning column 42 is in insertion fit with the positioning groove 41, and the insertion structure of the positioning column 42 and the positioning groove 41 with at least two different positions is provided, so that the sleeve liner 21 and the sleeve body 22 are relatively fixed in the circumferential direction of the output shaft 11.
Preferably, the positioning post 42 includes a first positioning post and a second positioning post, the first positioning post is a strip shape, and the length of the first positioning post is greater than the width thereof and greater than the length of the second positioning post; the second positioning column is a protruding structure, and the height of the protrusion of the second positioning column is not larger than the width of the second positioning column.
Specifically, the positioning posts 42 of the two structures have different functions, referring to fig. 2 of the drawings, and the contact area between the elongated first positioning post and the sleeve liner in the axial direction of the output shaft is large, so that the stability of synchronous rotation between the sleeve body and the sleeve liner can be improved. However, since the first positioning column is a slender structure, the strength of the first positioning column when the first positioning column is subjected to the moment generated by the rotational shearing force may be insufficient, so that the strength of the positioning structure between the sleeve body and the sleeve liner is enhanced through the second positioning column, and the first positioning column is similar to a boss structure with low protrusion height and can share the moment generated by rotation, so as to improve the structural strength.
Further, the positioning structure 4 may also be directly realized by the external shape of the sleeve liner 21 and the internal shape of the caulking groove 221 of the sleeve body 22, for example, the external shape of the sleeve liner and the internal shape of the caulking groove 221 of the sleeve body 22 are both set to be non-circular, so that the sleeve liner 21 and the sleeve body 22 are relatively fixed in the circumferential direction of the output shaft 11 by the mutual matching of the external shapes and the structures. However, this arrangement has a disadvantage that the fitting precision is reduced due to the wear between the outer surface of the sleeve liner 21 and the caulking groove 221 of the sleeve body 22; meanwhile, the sleeve liner 21 is easy to generate appearance bump in the using process to cause appearance deformation, and further normal assembly between the sleeve liner 21 and the caulking groove 221 is affected.
In one embodiment, the first end face of the sleeve liner 21 is embedded with the magnet 5, and the surface of the magnet 5 is flush with the first end face.
Specifically, as shown in fig. 2, the first end surface of the sleeve liner 21 is a surface that contacts the bottom of the caulking groove 221 during installation, and the magnet 5 embedded on the first end surface is used to keep the sleeve liner 21 and the sleeve body 22 relatively fixed in the axial direction of the output shaft 11, and facilitate replacement and disassembly of the sleeve liner 21.
In one embodiment, the sleeve liner 21 is completely inserted into the insertion groove 221 of the sleeve body 22, and a second end surface of the sleeve liner 21 opposite to the first end surface is flush with a surface where the notch of the insertion groove 221 is located.
Specifically, as shown in fig. 2, the outer size of the sleeve liner 21 is completely consistent with the outer size of the inner space of the caulking groove 221, so as to improve the relative stability between the sleeve liner 21 and the sleeve body 22, and to substantially reduce the volume of the whole sleeve structure.
In one embodiment, the inner wall of the wrench socket 211 of the socket liner 21 for engaging a fastener to be operated has an outer pull groove 212, and the outer pull groove 212 is used for engaging a pulling tool to disengage the socket liner 21 from the recessed groove 221 of the socket body 22.
Specifically, as shown in fig. 2, the sleeve liner 21 is tightly fitted to the sleeve body 22, and an external tool is required for disassembly and assembly, especially in the case that the sleeve liner 21 is completely accommodated in the caulking groove 221 inside the sleeve body 22. Therefore, the inner wall of the wrench locking groove 211 of the socket liner 21 is provided with the outer pulling groove 212, and the socket liner 21 can be pulled out from the insertion groove 221 for replacement by hooking the outer pulling groove 212 with a hook-shaped outer pulling hook tool.
Preferably, the outer pull groove 212 extends continuously along the inner wall of the wrench socket 211 in a circumferential direction to form a ring structure, so that the outer pull hook can extend into the wrench socket 211 from any position to hook the outer pull groove 212. Meanwhile, the sinking direction of the outer pull groove 212 on the inner wall of the wrench clamping groove 211 inclines to the notch of the wrench clamping groove 211, so that the edge of the notch of the outer pull groove 212 close to one side of the notch of the wrench clamping groove 211 forms a hook-shaped structure, and the outer pull groove can be better matched with a hook tool.
In one embodiment, the sleeve body 22 further has an air vent 222 formed at the bottom of the groove 221 for communicating with the outside.
Specifically, as shown in fig. 2, since the fitting between the sleeve main body 22 and the sleeve liner 21 is tight, when the sleeve liner 21 is replaced or removed, it is necessary to consider the influence of air inside the caulking groove 221 of the sleeve main body 22. Specifically, air inside the caulking groove 221 is discharged through the discharge hole 222 when the sleeve liner 21 is installed, and outside air is introduced into the caulking groove 221 through the discharge hole 222 when the sleeve liner 21 is removed.
In one embodiment, the outer circumferential surface of the fixed shaft 31 has a plurality of latch teeth 311 uniformly distributed along the circumferential direction, the latch teeth 311 extend a certain length along the axial direction of the fixed shaft 31, and the portion of the supporting seat 32 sleeved on the fixed shaft 31 has tooth grooves for matching with the latch teeth 311.
Specifically, referring to fig. 1 of the drawings, the fixed shaft 31 and the support base 32 are fixed relative to each other in the circumferential direction by the engagement of the latch 311 and the tooth groove. When the angle of the support seat 32 is adjusted, the support seat 32 is moved outward along the axial direction of the fixed shaft 31 until the latch 311 is separated from the tooth groove, and then the angle of the support seat 32 is adjusted and the support seat 32 is moved in the opposite direction until the latch 311 is engaged with the tooth groove.
Preferably, the supporting component 3 includes two supporting seats 32, and the two supporting seats 32 are sleeved on the same fixed shaft 31 and are staggered with each other in the axial direction of the fixed shaft 31.
Specifically, two supporting seats 32 mainly used improve the stability of supporting, and when supporting, two supporting seats 32 can stagger certain angle each other in circumference, just so can form two stable strong points, based on triangular stable structure to can make the stable support of spanner on corresponding holding surface.
In addition, since the fixed shaft 31 and the support base 32 are relatively fixed in the circumferential direction by the engagement of the latch 311 and the tooth groove, the number and density of the latches 311 directly determine the accuracy of the angle adjustment, and the smaller the latch 311, the larger the number and the denser the latch 311, the higher the accuracy of the angle adjustment. Therefore, it is preferable that the number of the latch teeth 311 is not less than 20.
In one embodiment, the main body 1 is further provided with a shield 6, and the shield 6 is covered on one side of the fixed shaft 31.
Specifically, as shown in fig. 1, the protection cover 6 is located on one side of the fixed shaft 31 and is oriented above the lower side of the sleeve assembly 2, and the protection cover 6 is arc-shaped as a whole and is mainly used for protecting an operator. Specifically, a movable structure is adopted between the support seat 32 and the fixed shaft 31, and when the support seat 32 is subjected to reaction moment, the support seat is likely to fall off and pop out due to unstable connection, so that an operator is easily injured. Therefore, the protective cover 6 blocks the upper region of the fixed shaft 31, and the support seat 32 is prevented from being directly ejected without affecting the adjusting function of the support seat 32 (the main angle adjusting range of the support seat 32 corresponds to the lower part and the two sides).
