Description
Technical Field
The utility model relates to a machine tool machining technical field especially relates to a tool changing manipulator for grinding machine.
Background
The tool changing manipulator is a main component part of a machining center for taking and changing tools in a tool magazine, can take out the tools in machine tool machining quickly, then puts the taken-out tools back to the tool magazine, and places the tools needing to be taken out at a tool mounting position so as to shorten the tool changing time in machine tool machining and further improve the machining efficiency.
However, the existing tool changing manipulator for the machine tool has a complex structure and high processing cost, and particularly, the components are multiple, so that the maintenance cost is high, the maintenance difficulty is high, and improvement is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tool changing manipulator for grinding machine, simple structure, processing cost are low, it is convenient and change the cutter convenient to maintain.
To achieve the purpose, the utility model adopts the following technical proposal:
a tool changing robot for a grinding machine, comprising: the tool changing assembly comprises a tool changing assembly and a driving piece for driving the tool changing assembly to rotate;
the tool changing assembly comprises a connecting arm and an elastic tool taking piece connected with the connecting arm;
the elastic cutter taking piece comprises a cutter taking cavity arranged on the connecting arm and an avoiding groove arranged on one side of the cutter taking cavity.
The cutter taking cavity is of a U-shaped structure, and the depth of the cutter taking cavity is four fifths of the width of the connecting arm;
the distance between the axis of the avoiding groove and the axis of the cutter taking cavity is 1.5 times of the width of the cutter taking cavity.
Wherein, the side walls at two sides of the avoidance groove are arranged in an S-shaped structure.
Wherein, the side walls at the two sides of the avoidance groove are arranged in a sawtooth structure.
Wherein, the connecting arm is processed by spring steel.
Wherein, be provided with the through-hole that is connected with the driving piece on the linking arm.
Wherein, still be provided with the lightening hole on the linking arm.
The utility model has the advantages that: the utility model provides a tool changing manipulator for grinding machine, utilizes the linking arm of spring steel processing, sets up on the linking arm and gets the sword chamber and dodge the groove for get the chamber wall in sword chamber and have the characteristics that reset after enlarging, accomplish the tool changing of cutter, have simple structure, need not to maintain, characteristics that the processing cost is low, the practicality is strong.

Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1.
Example 1
A tool changing robot for a grinding machine, comprising: a tool changing assembly 10 and a driving member 2 for driving the tool changing assembly 10 to rotate; the tool changing assembly 10 comprises a connecting arm 11 and an elastic tool taking piece 12 connected with the connecting arm 11; the elastic knife taking element 12 comprises a knife taking cavity 121 formed on the connecting arm 11 and an avoiding groove 122 formed on one side of the knife taking cavity 121. When the tool changing assembly is used, the tool changing assembly 10 is arranged at the bottom of a tool magazine and is driven by the driving piece 2 to rotate at the bottom of the tool magazine, at least 2 groups of the tool changing assembly 10 are arranged and are oppositely arranged at two ends of the connecting arm 11, and tool changing continuity of a machine tool is guaranteed; when the tool is taken, the center of the tool taking cavity 121 is opposite to the center of the tool in the heavy tool, the tool directly falls into the tool taking cavity 121, and the tool taking is completed by elastically clamping the tool shank due to certain elasticity of the inner cavity of the tool taking cavity 121; the avoiding groove 122 can enable the inner cavity of the knife taking cavity 121 to have larger elastic change, and the smoothness of elastic knife taking is ensured constantly.
Further, the knife taking cavity 121 is of a U-shaped structure, and the depth of the knife taking cavity 121 is a connecting arm
Four fifths of the width of the cutter cavity 11, the distance between the axis of the avoiding groove 122 and the axis of the cutter cavity 121 is 1.5 times of the width of the cutter cavity 121, so that the cutter cavity has reasonable elastic change, is convenient for clamping the cutter, has certain strength, reduces the fatigue rate of the elastic change and prolongs the service life.
Further, the side walls on the two sides of the avoiding groove 122 are arranged in an S-shaped structure, so that the elastic change strength of the avoiding groove is improved, and the phenomenon that the avoiding groove 122 is elastically fatigue and deformed due to multiple times of elastic changes is prevented.
Further, the connecting arm 11 is formed by processing spring steel, so that elastic deformation and resetting effects are good, and using requirements are met.
Further, be provided with the through-hole that is connected with the driving piece on the linking arm 11, driving piece 2 carries out the key-type connection through the through-hole on reduction gear shaft and the linking arm 11, connects reliably.
Furthermore, the connecting arm 11 is also provided with a lightening hole 111, so that the driving force of the driving piece 2 is reduced, and the power supply is saved.
Example 2
Unlike embodiment 1, the sidewall of the avoidance groove 122 has a zigzag structure.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
