Description

Technical Field

[0001] This utility model relates to the field of milling and drilling machine technology, and in particular to an automatic milling and drilling machine for housing parts. Background Technology

[0002] In modern manufacturing, housing parts serve as core load-bearing structures in fields such as machinery, automobiles, home appliances, and aerospace, and their processing quality directly affects the performance of the entire machine. These parts typically require multiple processes, such as drilling, on the housing surface, with stringent requirements for processing accuracy (such as hole diameter tolerance and positional accuracy). Moreover, with the accelerated pace of product iteration, the demand for multi-variety, small-batch production is becoming increasingly prominent.

[0003] However, the current drilling process for housing parts still faces many problems: Clamping and positioning on traditional drilling machines and lathes relies on manual operation. Workers must complete positioning through steps such as marking lines, trial drilling, and manual adjustment of fixtures. This is not only time-consuming and labor-intensive (averaging 3-5 minutes for clamping and positioning a single workpiece), but also, due to differences in human skill, the positioning accuracy is mostly maintained at ±0.1-0.2mm, which is insufficient to meet the requirements of high-precision machining (some housing hole tolerances require within ±0.05mm). At the same time, the intermittent nature of manual clamping results in equipment utilization rates of less than 60%, significantly deviating from the continuous production rhythm of automated production lines, becoming a key bottleneck restricting the improvement of production line efficiency.

[0004] In addition, some thin-walled shell parts are prone to deformation due to external clamping, resulting in out-of-tolerance internal cavity dimensions after machining and a high scrap rate. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic milling and drilling machine for housing parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic milling and drilling machine for housing parts includes a work platform, fixed slide rails, fixed slide rails symmetrically arranged on the work platform, a work frame arranged above the work platform, a power milling and drilling machine arranged at one end of the work frame away from the work platform, the fixed slide rails being inside the work frame, and a housing positioning component that slides on the fixed slide rails and cooperates with the power milling and drilling machine.

[0007] Furthermore, the housing positioning component includes a slide block, one end of which is connected to the movable end of a first cylinder. A fixed seat is fixedly connected to the upper surface of the slide block, and a fastener assembly is fixedly connected to the upper end face of the fixed seat. The fastener assembly includes a notched base, a notched middle section assembly, and a conical assembly, which are arranged sequentially from bottom to top.

[0008] Furthermore, the upper and lower ends of the middle section assembly are respectively provided with top finger assembly cavities, and a retaining member is installed in the top finger assembly cavity. The retaining member includes a top finger mounting block, and multiple top fingers slide radially on the top finger mounting block. An opening is opened at the position of the fastener assembly corresponding to the top finger.

[0009] Furthermore, the top finger slides within a T-shaped guide groove, which is formed on the top finger mounting block, and the multiple top fingers are driven by a second cylinder.

[0010] Furthermore, a positioning block is provided on the side of the slide block near the first cylinder.

[0011] Furthermore, the top finger has a U-shaped groove in the middle, the working surface of the top finger conforms to the inner wall of the housing, and the working surface of the top finger is provided with anti-slip components.

[0012] Compared with existing technologies, the advantages of the automatic milling and drilling machine for housing parts provided by this utility model are as follows: 1. During the entire milling and drilling process, the housing parts to be drilled can be automatically fed and unloaded, reducing labor costs; 2. The conical assembly can fit the inner cavity surface of the shell parts. The head of the conical assembly is gradually tapered, which can guide the shell parts, greatly reducing the difficulty of inserting the device into the inner cavity of the shell and avoiding jamming. The contact point between the shell parts and the conical assembly will automatically slide along the conical surface to the central symmetrical position, which can better position the shell parts. 3. The top finger, pushed by the second cylinder, can press against the housing parts. The working surface of the top finger is adapted to the curved surface of the housing parts, and the working surface of the top finger is also equipped with anti-slip parts, which can further secure the housing parts.

Therefore, they should not be construed as limitations on this utility model.

[0016] Example 1:

[0017] As shown in the attached illustration. Figures 1-5 As shown, an automatic milling and drilling machine for housing parts includes a work platform 1, fixed slide rails 2, fixed slide rails 2 symmetrically arranged on the work platform 1, a work frame 3 arranged above the work platform 1, the work frame 3 is an open rectangular frame with the opening facing downwards, a power milling and drilling machine 4 is arranged at one end of the work frame 3 away from the work platform 1, two fixed slide rails 2 are inside the work frame 3, and a housing positioning component 5 is also included. The housing positioning component 5 slides on the fixed slide rails 2 and works in corresponding cooperation with the power milling and drilling machine 4.

[0018] The housing positioning component 5 reciprocates along the fixed slide rail 2 on the working platform 1, achieving automatic entry and exit. During operation, the housing positioning component 5 corresponds to the power milling and drilling machine 4. The power milling and drilling machine 4 is a conventional milling and drilling machine, including a motor, drill bit, feed box, and cooling pipe. During operation, the drill bit corresponds to the top of the housing part 6. The cooling pipe provides coolant to the drill bit during operation. After drilling, the housing positioning component 5, carrying the housing part 6, moves away from under the power milling and drilling machine 4 for the next operation. The power milling and drilling machine 4 controls the feed speed of the drill bit through an externally connected control system.

[0019] The housing positioning component 5 includes a slide 51, one end of which is connected to a first cylinder 52. A fixed seat 53 is fixedly connected to the upper surface of the slide 51 by bolts, and a fastener assembly 54 is fixedly connected to the upper end of the fixed seat 53.

[0020] The bottom surface of the slide block 51 slides on the slide rail 2 via a fixedly connected slider. Driven by the movable end of the first cylinder 52, the slide block 51 reciprocates on the work platform 1, causing the fastener assembly 54 to reciprocate on the upper plane of the work platform 1. The first cylinder 52 is electrically connected to the external control system.

[0021] The fastener assembly 54 is approximately 484 mm high and includes a notched base 541, a notched intermediate section assembly 542, and a conical assembly 543, which are arranged sequentially from bottom to top.

[0022] The middle section assembly 542 has finger mounting cavities 544 at its upper and lower ends. Each finger mounting cavity 544 contains a clamping element, including a finger mounting block 545. Multiple fingers 546 slide radially on the finger mounting block 545, and these fingers 546 slide within a T-shaped guide groove 547. The T-shaped guide groove 547 is formed on the finger mounting block 545. The multiple fingers 546 are driven by a second cylinder. The fastener assembly 54 has openings 548 corresponding to the fingers 546.

[0023] The base 541 is connected to the intermediate section assembly 542 by bolts. The intermediate section assembly 542 has a top finger assembly cavity 544 near the base 541. A top finger mounting block 545 is fixedly connected to the top finger assembly cavity 544 by bolts. T-shaped guide grooves 547 are evenly distributed along the circumference of the top finger mounting block 545. A sliding block slides in the T-shaped guide grooves 547. A top finger 546 is fixedly connected to one end of the sliding block by bolts. The other end of the sliding block is connected to the movable end of the second cylinder. The second cylinder is integrated inside the top finger mounting block 545 and is controlled by an external control system. Similarly, a top finger assembly cavity 544 is also provided near the conical assembly 543 of the intermediate section assembly 542. The structure of the top finger assembly cavity 544 near the base 541 is the same, and a clamping member is also installed therein.

[0024] The top fingers 546 at both ends of the intermediate section assembly 542 move radially along the T-shaped guide groove 547 via the piston end of the second cylinder. The top fingers 546 then extend out of the surface of the intermediate section assembly 542 through the opening 548 and firmly abut against the inner cavity of the clamped housing part 6. In this embodiment, there are three top fingers 546 in the clamping member, which are distributed around the circumference of the top finger mounting block 545. The three top fingers 546 can constrain the radial runout of the housing part 6 and ensure consistent positioning. The three top fingers 546 form a "triangular support system" to evenly distribute the axial force of the drill bit during drilling.

[0025] To ensure a more stable clamping of the housing part 6 by the top finger 546, the working surface of the top finger 546 conforms to the inner cavity sidewall of the housing part 6, and an anti-slip component is provided on the working surface of the top finger 546. A U-shaped groove is provided in the middle of the top finger 546. The bolt passes through the U-shaped groove before being threaded onto the sliding block. The U-shaped groove structure in the middle of the top finger 546 alters the force distribution. During use, the U-shaped groove disperses the pressure on the top finger 546, reducing localized stress concentration, delaying wear and deformation of the top finger 546, and extending its service life. The anti-slip component can be made of materials such as rubber, silicone, or polyurethane. Its excellent anti-slip properties ensure a secure clamping of the housing part 6, guaranteeing a reliable clamping.

[0026] The conical assembly 543 fits precisely with the top of the housing part 6. The conical structure of the assembly 543 utilizes a self-centering principle to allow the housing part 6 to quickly align with the center, automatically correcting itself during placement, reducing manual centering time and improving clamping efficiency. Furthermore, it disperses stress; the large contact area between the conical surface and the inner cavity of the housing part 6 disperses clamping force, preventing localized pressure concentration and crushing of the thin-walled housing part 6, thus protecting it.

[0027] In order to ensure that the slide 51 is positioned when it retracts, a positioning block 55 is provided on the side of the slide 51 near the first cylinder 52, and the positioning block 55 is fixed on the upper plane of the work platform 1.

[0028] When using, refer to Figure 1 and Figure 2 First, the housing part 6 is placed on the housing positioning member 5. The external control system controls the top finger 546 to extend and clamp the housing part 6. The first cylinder 52 pushes the slide 51 along the fixed slide rail 2. When the slide 51 moves to correspond with the power milling drill 4, the slide 51 stops moving, and the power milling drill 4 starts working. The motor rotates, driving the drill bit to start feeding and rotating, drilling the corresponding hole on the housing part 6. After drilling is completed, the first cylinder 52 takes the slide 51 back along the fixed slide rail 2. After returning to the positioning block 55, the control system controls the top finger 546 to retract. At this time, the housing part 6 is no longer clamped by the top finger 546, and the robotic arm can remove the housing part 6 from the housing positioning member 5 to proceed to the next process. The housing parts 6 that need to be drilled are placed back into the housing positioning member 5, and the above process is repeated until the drilling of all housing parts 6 is completed.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
