Description

Technical Field

[0001] The invention relates to the technical field of profile processing equipment, and in particular to a highly efficient and precise hole position comprehensive processing device for aluminum profiles. Background Art

[0002] Aluminum profile is a long strip material with specific shape and size with aluminum as the main component. It has the advantages of light weight, high strength and corrosion resistance. It is widely used in many fields such as construction, transportation, electronics, machinery, etc.

[0003] The purpose of hole processing and tapping on aluminum profiles is to facilitate installation and connection. Through holes and tapping, bolts, screws and other connectors can be used to fix aluminum profiles to other components to build complex structures. For example, when building aluminum alloy door and window frames, holes and tapping are required on the profiles to install hinges, locks and other components. At the same time, sensors, control lines, etc. can be installed through hole processing and tapping. Reasonable distribution of holes and tapping can enhance the connection strength between profiles, thereby improving the stability and reliability of the entire structure.

[0004] Existing equipment for hole processing and tapping of aluminum profiles is generally independently set up, similar to the form of a production line. For the processing of aluminum profiles of different shapes and sizes, it is necessary to frequently replace tappers and hole openers of different specifications, which increases the complexity and time cost of operation, is inefficient, and is prone to slow processing speeds and cannot meet the problems of large-scale production. In addition, manual intervention increases labor costs and is prone to human errors.

[0022] Working principle: In actual use, the device of the present invention mainly includes the following operating steps:

[0023] Step 1: Loading of profiles: The profiles to be processed are sent from the loading rack to the fixed fixture, and the profiles are fixed and clamped by the fixed fixture. Then the electric slide drives the fixed fixture to move to the lower part of the multi-specification hole tapping mechanism to prepare for the hole tapping processing operation;

[0024] The second step is the processing of opening and tapping the profile: after the profile is transported to the corresponding position, the motor inside the drive box is started to operate, and one of the ring plates can be driven to rotate through the meshing action of the gears and teeth. Since the two ring plates are in a meshing relationship, they will rotate synchronously, so that the multi-specification impact components and tappers installed on the two ring plates are adjusted to the corresponding positions. When the impact component is selected, the corresponding tapper will be adjusted to the same horizontal position. After aligning the profile, the hydraulic cylinder installed in the mounting frame is started to drive the pressure block to move downward, contact the top of the impact rod in the impact component, and drive the hole opening head to open a hole in the profile. Then the hydraulic cylinder retracts the rod body and drives the pressure block to move upward. At this time, under the reset action of the reset spring, the hole opening head moves back. Then, by starting the first linear module, the connecting plate can be translated as a whole for a distance, so that the tapper is aligned with the place where tapping is required, and the opened hole can be tapped;

[0025] Step 3: Partial grinding of profiles: In this step, after the profile is drilled and tapped, the electric slide cooperates with the fixing fixture to transport it to the lower part of the grinding mechanism. By starting the second linear module, the position of the electric turntable can be adjusted. Because the grinder is installed on the side of the rotating seat, the grinding position of the grinder can be adjusted by starting the electric turntable. The end of the grinder can be extended and rotated to process the part of the profile that needs to be polished, remove the oxide layer and stains on the surface, and then let the profile pass through the lifting effect of the lifter and unload from the unloading rack to complete the processing process;

[0026] In the above steps, if the profile needs to be turned over or adjusted during processing, it first needs to be clamped by the fixed fixture, and then the electric slide rail is started to drive the pusher to move to the profile position, and the electric clamp is used to clamp one end of the profile, and the electric clamp is driven by the driving motor to rotate, so that the processing surface of the profile can be changed;

[0027] At the same time, during the use of the device, part of the waste generated in the hole drilling and tapping process falls into the inside of the receiving plate for recovery, and the other part is collected by the dust collecting mechanism which is always started. Specifically, the exhaust fan generates suction to suck metal powder into the bellows and drop it into the drawing groove for collection. Two dust collecting mechanisms are provided, which are respectively installed on both sides of the base frame. The suction port parts thereof are connected through the middle frame. By setting up the dust collecting mechanism, the powder waste generated in the processing process can be collected.

[0028] The present invention provides a highly efficient and precise hole position comprehensive processing device for aluminum profiles. It has the following beneficial effects:

[0029] 1. The present invention provides an integrated multi-specification hole opening and tapping mechanism, which can make the two ring plates rotate synchronously through the meshing action of gears and teeth when processing profiles, so that the multi-specification impact components and tappers installed separately are adjusted to corresponding positions, and the profiles can be quickly opened and tapped through the synchronously adjusted multi-specification impact components and tappers, with high processing efficiency.

[0030] 2. The present invention sets a grinding mechanism. When the profile is drilled and tapped, the electric slide cooperates with the fixing fixture to transport it to the lower part of the grinding mechanism. By starting the second linear module, the grinding position of the grinder can be adjusted to make its end extend and rotate, so as to process the part of the profile that needs to be polished and remove the oxide layer and stains on the surface. After that, the profile is lifted by the lifting device and unloaded from the unloading rack to complete the processing. The whole process is connected with the drilling and tapping steps, and the degree of integration is good.

[0031] 3. The present invention sets two dust collecting mechanisms. Part of the waste generated during the hole opening and tapping process falls into the inside of the receiving plate for recovery, and the other part is sucked into the bellows by the suction force generated by the exhaust fan and falls into the drawing groove for collection. The powder waste generated during the processing can be collected to prevent the waste chips from being blown up. BRIEF DESCRIPTION OF THE DRAWINGS
