Technical Field

The utility model relates to a positioner, especially a quick positioner of axle hole welding.

Background

When a workpiece with a shaft hole is installed, a shaft is inserted into the shaft hole of the workpiece, and sometimes the inner surface of the shaft hole on the workpiece needs to be welded in the machining process, namely a layer of other material meeting the technological requirements is overlaid, and then cutting machining is carried out. In the shaft hole welding process, the welding device is installed on a tool, and a positioning hole of the welding device on the tool needs to be coaxial with a shaft hole on a workpiece. In the actual machining process, a bench worker manually lines and determines the position of a positioning hole of a welding device by taking a shaft hole as a reference, and sometimes the coaxiality error of the two holes is large due to accumulated tolerance, so that the welding quality of the shaft hole is influenced, and the working efficiency is low.

The utility model discloses a quick positioner of shaft hole welding, which comprises a support, the support comprises sleeve and the bottom plate of connecting the loop configuration in the sleeve bottom, is equipped with annular bracket in the sleeve, and bracket bottom surface fixedly connected with taper sleeve, the lateral surface of taper sleeve are big-end-up's the external cone face, are equipped with the otic placode opening on the sleeve, and the otic placode opening is at least three and along sleeve circumference evenly distributed, is located otic placode open-ended otic placode one end above the bracket, the other end suit of otic placode is on the bolt, the bolt with bottom plate threaded connection and perpendicular to bottom plate lie in on the bolt and be equipped with the spring between otic placode and the bottom plate, lie in threaded connection have a back of the body cap above the otic placode on the bolt, be equipped with the notch at the periphery of bottom plate, be equipped with switch magnet in this notch, switch magnet's bottom surface and the bottom surface coplane of bottom plate to switch magnet both sides face passes through magnet connecting seat and bottom plate fixed connection.

The utility model discloses a quick positioner of shaft hole welding, fix the frock of installing welding set during use on the bottom plate of this device, this device forms a whole with the frock part, welding set's axial lead and the coincidence of the axial lead of this device, be in coaxial state, the bottom plate of this device is located above the work piece, the bottom surface of bottom plate and the terminal surface coincidence (coplane) of work piece, the taper sleeve falls naturally, the little end of taper sleeve stretches into in the axial lead on the work piece, the shaft hole and the welding set of work piece are not coaxial this moment, then rotate the back cap on every bolt, make the otic placode move down, otic placode pushes down bracket and taper sleeve, the lateral surface and the contact of shaft hole port department edge angle of taper sleeve, this device and welding set together radial movement automatic adjustment central point under the pressure effect put, finally make welding set and shaft hole be in coaxial state, then utilize the actuation of switch magnet bottom to attract to fix, it makes the taper sleeve withdraw to adjust the back cap. During welding, the welding device rotates and axially moves along with the tool, and spiral surfacing is carried out on the inner surface of the shaft hole. The device has the advantages of simple structure, high working efficiency and accurate positioning of the welding device, and ensures the welding quality.

Detailed Description

As shown in fig. 1 and 2: the utility model discloses a quick positioner of shaft hole welding, including the support, the support comprises sleeve 4 and the bottom plate 2 of connecting at the loop configuration in sleeve 4 bottom, and sleeve 4 is welded fastening with bottom plate 2. An annular bracket 5 is arranged in the sleeve 4, and a taper sleeve 6 is fixedly connected to the bottom surface of the bracket 5 through a screw. The outer side surface 14 of the taper sleeve 6 is an external taper surface with a large upper part and a small lower part. The sleeve 4 is provided with at least three lug plate openings 11, and the lug plate openings 11 are uniformly distributed along the circumference of the sleeve 4. The lug plate 7 is a lug plate, one end of the lug plate 7 positioned at the lug plate opening 11 is positioned on the bracket 5, the other end of the lug plate 7 is sleeved on a bolt 8, and the bolt 8 is in threaded connection with the bottom plate 2 and is vertical to the bottom plate 2. A spring 10 is sleeved between the lug plate 7 and the bottom plate 2 on the bolt 8, and a back cap 9 is connected with the upper surface of the lug plate 7 on the bolt 8 in a threaded manner. The periphery of the bottom plate 2 is provided with a notch, the notch is internally provided with a switch magnet 3, the bottom surface of the switch magnet 3 is coplanar with the bottom surface of the bottom plate 2, and two side surfaces of the switch magnet 3 are fixedly connected with the bottom plate 2 through a magnet connecting seat 12.

As shown in fig. 3: the utility model discloses a quick positioner of shaft hole welding, fix installation welding set's frock during use on bottom plate 2 of this device, this device forms a whole with the frock part, welding set's axial lead and the coincidence of the axial lead of this device, be in coaxial state, bottom plate 2 of this device is located on work piece 1, bottom plate 2's bottom surface and work piece 1's terminal surface coincidence (coplane), taper sleeve 6 falls naturally, the tip of taper sleeve 6 stretches into in the shaft hole 13 on the work piece 1, the shaft hole 13 of work piece 1 is not necessarily coaxial with welding set this moment, then rotate back of the body cap 9 on every bolt 8, make otic placode 7 move down, otic placode 7 pushes down bracket 5 and taper sleeve 6, lateral surface 14 and the contact of 13 edges and corners in shaft hole of taper sleeve 6, this device and the same radial movement automatic adjustment central point of welding set put under the pressure effect, finally make welding set and shaft hole be in coaxial state, then utilize the actuation of switch magnet 3 bottom to attract to close fixedly, it makes taper sleeve 6 withdraw to adjust back of the cap 9. During welding, the welding device rotates and moves axially along with the tool, and the inner surface of the shaft hole 13 is subjected to spiral surfacing.
