Description

Technical Field

[0001] The utility model relates to the field of drilling holes in door and window profiles, in particular to a gantry-type four-head drilling and milling device. Background Art

[0002] At present, during the processing of door and window profiles, it is necessary to process holes with various functions, such as drainage holes, connection holes for installing accessories (locks, door handles, etc.), and fixing holes for fixing angle brackets, etc. At present, the connection holes for installing accessories are generally realized by special drilling and milling processing equipment. Since it may involve multiple surfaces of the profile, in order to facilitate drilling and improve drilling efficiency, the use of four-head drilling and milling equipment has become the preferred method for more users. For example: Patent CN114406323A discloses a four-head drilling and milling processing center, which can drill and mill the four surfaces of the profile simultaneously or sequentially without turning the profile, thereby improving processing efficiency. However, the four-head drilling and milling processing center in the above technology is more suitable for processing connection holes or angle bracket fixing holes on the surface of vertical profiles, and is not applicable to the processing of some drainage holes, such as hidden drainage holes. Hidden drainage holes are designed by designing a groove on the window frame profile and drilling holes above the groove, such as Figure 4 As shown, if the four-head drilling and milling machining center is used to drill the hidden drain hole, the hidden drain frame may be easily bent and deformed due to the structure of the hidden drain frame, which may lead to safety hazards and even make the entire door and window profile scrapped. Therefore, the current four-head drilling and milling device has a limited application range and poor versatility, and it is necessary to improve the current four-head drilling and milling device. Utility Model Content

[0003] The current four-head drilling and milling equipment has a limited application scope and poor versatility. In addition to drilling and milling accessory connection holes and fixed angle code holes, it is easy to cause the hidden drainage frame to bend and deform when drilling and milling hidden drainage holes, which in turn poses a safety hazard and may even cause the entire door and window profile to be scrapped. At least one purpose or one aspect of the present application can solve the above problems, and a technical solution named gantry four-head drilling and milling device is specifically designed, which is specifically:

[0004] Gantry type four-head drilling and milling device, including:

[0005] Gantry;

[0006] A Z-direction sliding seat, the Z-direction sliding seat is slidably arranged on the gantry;

[0009] One of the drilling and milling head assemblies is arranged on the Y-direction sliding seat through a rotating seat. The rotation center of the rotating seat is connected to the Y-direction sliding seat through a rotary support shaft, and the side away from the rotation center is rotationally connected to the Y-direction sliding seat through a telescopic member.

[0013] Preferably, the passing space is square, and the length of the square passing space in the Y direction is greater than the width of the profile.

[0014] Preferably, the Z-direction sliding seat is a rectangular plate, and the passing space thereon is rectangular, and the passing space on the Z-direction sliding seat can cover the passing space on the Y-direction sliding seat.

[0015] Preferably, the drilling and milling head assembly includes a drill and a second telescopic cylinder. The drill is slidably arranged on a Y-axis sliding seat through a tool holder.

[0018] The utility model has the following technical effects through the above technical solution:

The hidden drainage holes of the profile can be drilled and milled by rotating a certain angle. The inclined drilling and milling can reduce the vertical downward force of the drainage frame, give the drainage frame a component force in the horizontal direction, and reduce the possibility of bending and deformation of the drainage frame.

This not only reduces the moving distance, but also makes the movement more flexible and convenient due to the light weight of the moving single drill bit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] like Figure 1-3As shown, the gantry-type four-head drilling and milling device includes a gantry 1, a Z-direction sliding seat 11, a Y-direction sliding seat 2 and four drilling and milling head assemblies. Among them, the structure of the gantry 1 is an existing structure, which usually includes two columns and a crossbeam. Under specific working conditions, the gantry 1 can be fixed as needed, that is, a fixed gantry 1, or a sliding seat can be set at the bottom of the column to cooperate with the guide rail on the ground or platform to enable it to move, that is, a mobile gantry 1. This application is specifically used on a door and window profile processing line and can be set to be mobile.

[0029] The Z-direction sliding seat 11 is slidably arranged on the gantry 1, specifically, two guide rails are arranged on the two columns, and the Z-direction sliding seat 11 is slidably arranged on the guide rails. The Y-direction sliding seat 2 is slidably arranged on the Z-direction sliding seat 11, specifically, a guide rail is arranged on the front and back of the Z-direction sliding seat 11, and the Z-direction sliding seat 11 is slidably arranged on the guide rails. The center of the Z-direction sliding seat 11 and the center of the Y-direction sliding seat 2 are respectively provided with a passing space 5 for the profile to pass through. The profile passing through the centers of the two sliding seats can shorten the moving distance of the Y-direction sliding seat 2 in the front and rear directions, and can also reduce the weight of the Y-direction sliding seat 2 and the Z-direction sliding seat 11, thereby reducing the weight of the entire device and improving the flexibility of movement.

[0030] It should be noted that the Z direction is based on the up-down direction in the orientation shown in the drawings, and the Y direction is based on the front-back direction in the orientation shown in the drawings.

[0031] Four drilling and milling head assemblies are arranged on the Y-direction sliding seat 2, of which two drilling and milling head assemblies are arranged on both sides of the through space 5 along the Y direction. For the convenience of description, the two drilling and milling head assemblies arranged along the Y direction are referred to as the front drilling and milling head assembly 3 and the rear drilling and milling head assembly 6. The other two drilling and milling head assemblies are arranged on both sides of the through space 5 along the Z direction, and are referred to as the upper drilling and milling head assembly 4 and the lower drilling and milling head assembly 7 in the present application.

[0032] In order to enable one of the drilling and milling head assemblies to rotate, one of the drilling and milling head assemblies is set on the Y-axis sliding seat 2 through a rotating seat 9. The rotation center of the rotating seat 9 is connected to the Y-axis sliding seat 2 through a slewing support shaft 12, and the side away from the rotation center is rotatably connected to the Y-axis sliding seat 2 through a telescopic part. The telescopic part drives the rotating seat 9 to rotate, thereby allowing the drilling and milling head assembly thereon to rotate a certain angle, so that it can tilt the hidden drainage holes on the profile. The tilted processing of the hidden drainage holes can reduce the vertical downward force on the drainage frame and reduce its bending deformation.

[0033] Furthermore, the telescopic member adopts a first telescopic cylinder 8, which can be an electric cylinder, an oil cylinder or a pneumatic cylinder, etc. The cylinder end of the first telescopic cylinder 8 is hinged to the Y-axis sliding seat 2, and the telescopic rod end is hinged to the rotating seat 9. The telescopic cylinder has a simple structure and is more suitable for the smaller installation space here, and is easy to implement.

[0034] Furthermore, the rotating seat 9 is specifically connected between the front drilling and milling head assembly 3 and the Y-direction sliding seat 2, or between the rear drilling and milling head assembly 6 and the Y-direction sliding seat 2. In this way, the front drilling and milling head assembly 3 can be aligned with the drilling position by only fine-tuning the position on the Y-direction sliding seat 2, without moving the entire Y-direction sliding seat 2, which not only reduces the moving distance, but also makes the movement more flexible and light because the weight of a single drill bit is light.

[0035] It should be understood that if the hidden drainage hole is to be drilled and milled at an angle, the position of each drilling and milling head assembly needs to be moved. If the upper drilling and milling head assembly 4 and the lower drilling and milling head assembly 7 want to move in the front and rear directions, the entire Y-axis sliding seat 2 must be moved. In comparison, the front drilling and milling head assembly 3 or the rear drilling and milling head assembly 6 can be moved in the front and rear directions independently, which is more flexible and lightweight.

[0036] Furthermore, the Y-axis sliding seat 2 is a diamond-shaped plate, and the four drilling and milling head assemblies are correspondingly arranged at the four corners of the diamond-shaped plate. Such a layout can reduce the space occupied by the four drilling and milling head assemblies in the front and rear directions, making the structure more compact.

[0037] Furthermore, the through space 5 is a square, and the length of the square through space 5 in the Y direction is greater than the width of the profile. Since the cross-sectional shape of most profiles is a square, the through space 5 is set as a square here to match the cross-sectional shape of the profile, thereby avoiding redundant length in a certain direction and reducing unnecessary space occupation. In addition, the through space 5 is greater than the width of the profile, so that the Y-direction sliding seat 2 can move a certain distance relative to the profile, thereby adjusting the alignment position of the drilling and milling head assembly and the profile punching point.

[0038] Furthermore, the above-mentioned Z-direction sliding seat 11 is a rectangular plate, and the passing space 5 thereon is rectangular. The passing space 5 on the Z-direction sliding seat 11 can cover the passing space 5 on the Y-direction sliding seat 2, so that the passing space 5 is determined by the size of the passing space 5 on the Y-direction sliding seat 2, and the passing space 5 on the Z-direction sliding seat 11 can reduce the weight of the Z-direction sliding seat 11 as much as possible.

[0039] Furthermore, the structures of the four drilling and milling head assemblies are the same. The structure of the latter drilling and milling head assembly 6 is described here as an example. It includes a drill 601 (the drill 601 here refers to a combination of a cutter head and a rotating motor) and a second telescopic cylinder 602. The second telescopic cylinder 602 can also adopt an electric cylinder, an oil cylinder, and an air cylinder. The drill 601 is slidably arranged on the Y-axis sliding seat 2 through the tool seat. The second telescopic cylinder 602 is connected between the tool seat and the Y-axis sliding seat 2 to drive the drill 601 to approach or move away from the profile.

[0040] Furthermore, since all components are arranged on the right side of the Z-direction sliding seat 11, in order to balance the force, two balanced telescopic cylinders 10 are connected between the Z-direction sliding seat 11 and the gantry 1, and the two balanced telescopic cylinders 10 are symmetrically arranged on both sides of the Z-direction sliding seat 11 along the Y direction.

[0041] Furthermore, the driving of the above-mentioned Z-axis sliding seat 11 and the driving of the Y-axis sliding seat 2 are respectively driven by the Z-axis driving component 14 and the Y-axis driving component 13. The Z-axis driving component 14 is connected between the Z-axis sliding seat 11 and the gantry 1, and the Y-axis driving component 13 is connected between the Y-axis sliding seat 2 and the Z-axis sliding seat 11. The Z-axis driving component 14 and the Y-axis driving component 13 here adopt the currently existing motor screw method. The motor screw drive can ensure the accuracy of the moving position, which is more suitable for the environment with high precision requirements in this application.

[0042] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0043] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
