Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profile processing, in particular to double-station processing equipment with adjustable spacing and angles for household appliance bent pipe aluminum handles. Background Art

[0002] Aluminum profiles are a common substrate used in industry, often requiring multiple or multiple groups of anchor holes and threaded holes to be machined into their surfaces. Conventional machining equipment utilizes CNC machining centers, where the tool head moves to a specific location for machining, or the tool head must be replaced before machining begins. Spacing between multiple groups of holes must be maintained, both within and between groups. This is especially true when the same hole requires multiple machining operations, such as drilling followed by tapping a threaded hole. The tool position must be precise for each machining operation. In some cases, the vertical angle of the holes being machined may also need to be altered.

[0003] Handle aluminum profiles are common aluminum alloy components used in home decoration and household appliances. Their characteristics are: the main body is made by bending a tubular profile, and threaded holes need to be machined at both ends of the handle, which is firmly fixed to the furniture door or household appliance door with bolts or screws. Therefore, the processing accuracy of the threaded holes is an important link in the production of bent tube aluminum handles.

[0004] Therefore, when using an ordinary three-axis single-head machining center to process the bent aluminum handle in the above situation, the efficiency is extremely low; and it is impossible to complete the operation of changing the vertical angle processing. Summary of the Invention

[0005] The purpose of the utility model is to provide a double-station processing equipment with adjustable spacing and angle of household appliance bent tube aluminum handles, which can be specially used for the processing of household appliance bent tube aluminum handles. Utilizing the symmetrical processing hole positions at both ends of the bent tube aluminum handles, the equipment is installed with two sets of power heads, which simultaneously perform drilling or tapping processing on the symmetrical positions at both ends of the bent tube aluminum handles, and has the advantages of high processing efficiency, high processing precision, and convenient operation; and the angle of the power head is adjustable, which can adapt to various processing scenarios.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0007] A double-station processing equipment for household appliance bent tube aluminum handles with adjustable spacing and angle. A fixed power head group is arranged on the equipment frame, and a variable power head group is also arranged at the same plane height as the frame. The variable power head group is fixed on a power head movable base plate, and the power head movable base plate is slidably connected to the power head guide rail through a slider, and the power head guide rail is fixed to the frame; a workbench is arranged below the fixed power head group and the variable power head group, the bottom of the workbench is slidably connected to the workbench track through a slider, and one side of the workbench is connected to the workbench translation drive mechanism.

[0008] The power head is a purchased drilling power head with its own drive motor. Connected to the workshop's high-pressure air, the internal cylinder drives the drill chuck downward. A coolant nozzle is installed on one side of the power head's tool, connected to a coolant pump via a pipe to cool and lubricate the aluminum handle during the processing of the bent pipe.

[0009] Typically, in a fixed power head assembly, one head is equipped with a drill and the other with a tap. In a variable power head assembly, one head is equipped with a drill and the other with a tap. The aluminum profile is first drilled by both heads, then the worktable is moved horizontally before the two heads perform the tapping process. This not only shortens the travel of the aluminum handle, but also increases processing efficiency and facilitates operator operation.

[0010] A wire block is installed in the middle of the power head moving base plate, a wire hole of the wire block is threadedly connected with a hand wheel screw rod, and the hand wheel screw rod is fixedly installed on the frame through a bearing.

[0011] When the distance between the fixed power head group and the variable power head group needs to be changed, the handwheel screw rod is shaken to change the position of the movable base plate, which can adapt to drilling and tapping operations of different sizes.

[0012] The fixed power head assembly is mounted on a positioning plate A, which is attached to the frame via an unpowered shaft. Positioning plate A can be manually rotated around the shaft. Nuts are screwed into the threads at each end of the shaft, pressing the positioning plate A against the frame to maintain a fixed angle. Scales are provided on the frame and on the edge of the positioning plate, allowing the operator to adjust the rotation angle of the positioning plate A using these scales.

[0013] The variable power head assembly is mounted on a positioning plate B, which is attached to the power head's moving baseplate via an unpowered shaft. Positioning plate A can be manually rotated around the shaft. Nuts are screwed into the threads at each end of the shaft, pressing the positioning plate A against the power head's moving baseplate to maintain a fixed angle. Scales are provided on the power head's moving baseplate and on the edge of the positioning plate, allowing the operator to adjust the rotation angle of positioning plate A using these scales.

[0014] There are several arc-shaped elongated holes on the positioning plates A and B. Horizontal bolts pass through the elongated holes, and nuts are tightened behind the holes to secure the power head to the positioning plates. To change the tilt angle of the power head, loosen the nuts, adjust the angle of the power head, and then tighten the nuts to complete the angle adjustment.

[0015] The workbench translation drive mechanism includes a horizontal hydraulic cylinder installed on the side, the hydraulic cylinder piston rod is connected to the connecting plate, and the connecting plate is fixedly connected to the workbench; the hydraulic cylinder is connected to the hydraulic pump at the bottom of the frame through a hydraulic pipe.

[0016] The workbench is moved horizontally by hydraulic drive; a number of pneumatic clamps are installed on the workbench to clamp aluminum profiles.

[0017] An aluminum chip collecting trough is provided at the bottom of the frame, and a collecting funnel is provided above the aluminum chip collecting trough. The processed aluminum chips fall into the collecting trough through the funnel.

[0018] Utility model advantages

[0019] 1. This utility model uses multiple sets of power heads and a transversely movable workbench to achieve multi-station simultaneous processing of multiple holes in aluminum profiles with symmetrical hole processing types. Compared with the single-head machining center that processes holes one by one, the tool stroke is greatly reduced, and dual tools are fed simultaneously for processing, which greatly improves the processing efficiency. It is estimated that compared with the previous single-head machining center processing solution, the processing efficiency is increased by nearly 400%.

[0020] 2. The position of the variable power head group can be adjusted arbitrarily and infinitely, which can realize the processing of different lengths and different hole spacings. It has high adaptability and meets the needs of flexible production.

[0021] 3. The utility model realizes manual adjustment of the angle of the power head by installing the power head on the positioning plate; compared with the traditional three-axis machining center, the problem of whether the angle can be adjusted is solved; compared with the expensive four-axis machining center, the cost is greatly reduced, and it can be used for the processing of large quantities of inclined drilling and bending aluminum handles.
