Description

Technical Field

[0001] The invention relates to the technical field of profile processing, in particular to a profile milling positioning mechanism, double-end face milling equipment and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the prior art, end milling machine equipment is usually used to perform end face processing on profiles such as aluminum profiles, so as to perform milling and tenoning and other operations on the end face of the processed profile, so that the processed profile can be assembled with other profiles. The existing end milling machine equipment only rigidly positions the profile and starts milling work directly after positioning. The inventor has found that there are certain errors when placing the profile by machine or manually, that is, there are errors in the end of the profile due to placement. If it is directly milled without correction, it will affect the processing accuracy. However, rigid positioning cannot eliminate the influence of profile errors on the tenon milling accuracy, that is, it cannot eliminate the processing accuracy caused by placement errors, which easily causes the milled profile to have a large gap when docking with other profiles. This requires an additional process of sealing the end face of the profile in the next step of processing, resulting in low work efficiency and increased labor and material costs.

[0004] In addition, there is also a double-end milling equipment in the prior art, which has a fixed head and a movable head. Both heads are set with hard positioning. If there is an error in placement, one end exceeds the set position and the other end is less than the set position. In this way, after milling, one end is milled beyond the range and the other end is milled less. The milling accuracy of the profile is low, which affects the subsequent processing of the profile. Summary of the invention

There is at least one connecting member, and when there are two or more connecting members, the multiple connecting members are arranged vertically and parallel to each other.

[0012] A profile milling positioning mechanism as described above also includes a support seat, which is fixedly connected to the frame. A sliding component is arranged between the mounting plate and the support seat. The support seat is L-shaped, and the linear drive component passes through one side of the support seat and is fixedly connected to the mounting plate.

[0013] In the second aspect, the present invention provides a double-end face milling equipment for a profile, comprising a fuselage, the fuselage supporting a fixed processing machine and a movable processing machine, the movable processing machine being movable relative to the fuselage, the fixed processing machine and the movable processing machine both being provided with the milling mechanism described above, the fixed processing machine and the movable processing machine both being provided with the profile milling positioning mechanism described above, a workbench being provided on one side of the fixed processing machine and the movable processing machine, and a distance being set between the workbench and the profile milling positioning mechanism on this side.

[0017] The movable processing machine is moved according to the length of the profile to be processed;

[0018] The profile is supported by two work tables of a fixed processing machine and a movable processing machine;

[0019] If one end of the profile exceeds the working table on that side by a distance greater than the set value, the end face of the profile contacts the positioning piece and pushes the positioning piece to move relative to the connecting piece. During the movement, the displacement sensor obtains the displacement change information of the positioning piece relative to the mounting plate and sends it to the controller;

[0020] The controller obtains the displacement change information of the positioning member relative to the mounting plate, and controls the moving component of the milling mechanism in the fixed processing machine or the movable processing machine where the worktable on that side is located to move back a set distance, and controls the moving component of the milling mechanism in the movable processing machine or the fixed processing machine on the other side to move forward a set distance, so as to realize the precise positioning and displacement compensation of both ends of the profile;

The movable processing machine and the fixed processing machine are both provided with a profile milling positioning mechanism, which can position both ends of the profile. After the profile on one side is placed beyond the set range, it pushes the positioning piece on that side, and the displacement sensor on that side sends information to the controller. The displacement sensor on the other side detects that the displacement change is zero, and the controller can know which end of the profile has exceeded and which end has not been put in place. In this way, the controller controls the movable components on both sides to act, and realizes effective compensation for the placement error, thereby ensuring the milling accuracy of the two ends of the profile, effectively improving the milling accuracy, reducing the production cost, and no subsequent glue filling is required, which is beneficial to improving the installation efficiency of the profile.

Considering the installation space, the working surfaces of the two milling cutters are opposite but staggered.
