Description
Technical Field
The invention relates to an installation tool, in particular to a lifting installation tool.
Background
The crankshaft diameter of the EA888 engine under the popular flag adopts a process route of rough/finish turning, surface quenching and rough/finish grinding. The AF90 is adopted to grind the main journal, the connecting rod journal excircle and the grinding flange excircle, which are the working procedures with the highest requirements on the processing precision and the surface roughness in the whole crankshaft production.
In a general case, a CBN (Cubic Boron Nitride, cubic boron carbide) grinding wheel is generally adopted in the grinding process, the CBN grinding wheel is structured by sticking a CBN sand strip on the circumference of a steel grinding wheel matrix, and after the sand strip is worn, a machine tool corrects the surface of the CBN grinding wheel through a diamond wheel corrector. When the CBN grinding wheel is used for grinding, the grinding wheel needs to be replaced as the CBN particles gradually fall off and are worn to a certain degree in the grinding and grinding wheel correction process.
It should be noted, however, that the grinding wheel is originally placed horizontally in the bin, but when the grinding wheel is mounted on the grinding machine spindle, it is required to mount the grinding wheel vertically, and therefore it is often necessary to turn the angle of the grinding wheel. When the automatic grinding device is in practical application, the CBN grinding wheel matrix is made of steel, the weights of the AF90 main journal and the connecting rod journal grinding wheels are 50KG, the weights of the AF110 flange grinding wheels are 90KG, the CBN grinding wheel is brittle, and the whole grinding wheel is scrapped once collision is generated in the process of carrying and overturning the grinding wheel.
In the prior art, the replacement process of the grinding wheel is as follows: and taking out the grinding wheel from the grinding wheel box, then mounting the grinding wheel on the auxiliary bracket, and then lifting the grinding wheel by using the fixed grinding wheel lifting tool to mount the grinding wheel on the main shaft of the grinding machine. At present, all operations are carried and adjusted by the manpower of operators, and the manual carrying mode is time-consuming and labor-consuming, and also easily causes safety accidents, and the risks of colliding with the surface of the grinding wheel and falling and smashing the grinding wheel to hurt the operators exist. Thus, there is an urgent need for an installation tool that assists in the replacement of grinding wheels.
In order to solve the above problems in the prior art, some researchers have conducted related optimization designs, and have obtained the following improvements:
1. and a plurality of operators carry the grinding wheel together to share the gravity of the grinding wheel.
2. The grinding wheel is handled using an industrial robot.
3. Manufacturing a mobile trolley with lifting and overturning functions, and carrying and installing grinding wheels.
However, it should be noted that the three improvements still have certain defects, and when the above-mentioned improvement 1 is adopted, as the shape of the grinding wheel is a smooth cylinder, multiple operators can jointly carry the position which is not suitable for grabbing, so that the force is not convenient to apply; moreover, the coordination of multiple persons is at an uncoordinated risk, so that the grinding wheel is easy to slide down, and serious production safety accidents are caused. When the improvement scheme 2 is adopted, the technical difficulty and the cost for carrying the grinding wheel by using the industrial robot are high. When the above-mentioned improvement 3 is adopted, because the weight of the grinding wheel is very large, the stability and balancing problems of the center of the mobile trolley are difficult to deal with along with the position movement of the grinding wheel in the installation process, and the mobile trolley has the possibility of rollover.
Therefore, the technical scheme for accurately and effectively assisting in mounting the grinding wheel while ensuring the safety of operators still lacks at present, and in order to solve the problems in the prior art, the invention expects to obtain a lifting mounting tool for the grinding wheel, which is different from the prior art, and the lifting mounting tool can assist in carrying and mounting the grinding wheel by utilizing the lever principle, and has the advantages of simple structure, simple and convenient manufacture and maintenance, good reliability and convenient use and operation; the lifting installation tool is used for installing the grinding wheel, so that the labor intensity of operators can be effectively reduced, the safe production can be ensured, the lifting installation grinding wheel is efficient and safe, the applicability is very wide, the lifting installation tool can be effectively applied to lifting installation occasions of grinding wheels of all grinding machines, and the lifting installation tool has good popularization prospect and application value.

After the first external force is released, the torsion bar 3 no longer rotates around its own axis, and the lever 62 removes the force applied to the positioning rod 5.
At this time, the spring 51 sleeved outside the positioning rod 5 may pull the positioning rod 5 by an elastic force, so that the positioning rod 5 is inserted into the second positioning groove 42, thereby realizing the switching of the positioning rod 5 from the first positioning groove 41 into the second positioning groove 42.
Of course, in some other embodiments, the operator may also control the positioning rod 5 to switch from the second positioning slot 41 to the first positioning slot 42 as required, and the operation principle is the same as that described above, and will not be repeated here.

wherein the transmission assembly comprises: a transmission block connected to the torsion bar; one end of the lever is connected with the transmission block, and the other end of the lever is hinged with the upper end part of the positioning rod; when the torsion bar rotates around the axis of the torsion bar, the lever is driven to pull the positioning rod to move along the axial direction of the torsion bar so as to be separated from the first positioning groove or the second positioning groove;
wherein the torsion bar locking device comprises: a locking groove arranged on the torsion bar seat; the tail end of the pressing block is arranged in a square groove formed in the torsion bar, and a chute is formed in the tail end of the pressing block; a pull rod slidably arranged in the torsion bar, wherein the axial direction of the pull rod is consistent with the axial direction of the torsion bar; the torsion bar locking pin is fixedly connected with the head end of the extraction rod and extends outwards in the radial direction of the extraction rod; a movable pin passing through the draw bar and the chute; when the torsion bar locking device is in a locking station, the torsion bar locking pin is correspondingly arranged in the locking groove; when the pressing block is pressed down towards the torsion bar, the drawing rod is driven to move towards the tail end of the torsion bar in the axial direction, so that the torsion bar locking pin at the head end of the drawing rod is separated from the locking groove, and in this state, the torsion bar can rotate around the axis of the torsion bar under the action of first external force.
2. A handling and mounting tool for grinding wheels according to claim 1, wherein the body is provided with a lifting hole and/or a handle.
3. A handling and mounting tool for grinding wheels as claimed in claim 1, wherein said body is provided with a bolt seat on which bolts for mounting the grinding wheels are provided.
4. A handling and mounting tool for grinding wheels according to claim 1, wherein said body is provided with a guide head.
5. A handling and mounting tool for grinding wheels as defined in claim 4 wherein said guide head is provided with magnets.
6. The trolley mounting tool for grinding wheels of claim 1 wherein the locating bar is sleeved with a spring that allows the locating bar to be retained in either the first or second locating slot without being subjected to the first external force.
7. The swing attachment tool for grinding wheels as defined in claim 1, further comprising a rod spring which is fitted around the outer periphery of the rod and to which an elastic force is applied to move the rod toward the head end of the torsion bar.
