Technical Field

[0001] This utility model relates to the technical field of gantry machining centers, specifically a five-sided gantry machining center. Background Technology

[0002] A five-sided gantry machining center typically consists of a bed, crossbeam, columns, and milling head. Its structural features include a horizontally arranged bed, a milling head mounted on the crossbeam, and a gantry frame formed by two columns and a connecting beam. This structure ensures stability during machining, making it suitable for processing large workpieces.

[0003] Currently, machining centers involve the exchange of vertical and horizontal spindle heads. The exchange mechanism needs to be stable, reliable, and accurately positioned. The existing brackets for exchanging vertical and horizontal spindle heads are usually exposed to the outside. If metal shavings or larger dust particles enter the area where the spindle head is placed during production, it will affect the stability of the spindle head and cause it to tilt, affecting the spindle head and reinstallation. Utility Model Content

[0004] The purpose of this utility model is to provide a five-sided gantry machining center to at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a column and a bracket moving assembly. The bracket moving assembly includes a first guide seat and a second guide seat. A first bracket is fixedly mounted on the top of the first guide seat, and a second bracket is fixedly mounted on the top of the second guide seat. A first cover plate is hinged above the first bracket, and a second cover plate is hinged above the second bracket. A rotating shaft is provided on the edge of the first bracket to drive one end of the first cover plate to rotate with a base point. A rotating shaft is provided on the edge of the second bracket to drive one end of the second cover plate to rotate with a base point. Rotating components for driving the first cover plate and the second cover plate to rotate are respectively provided on the edges of the first guide seat and the second guide seat.

[0006] The rotating assembly includes a hydraulic cylinder fixedly mounted on the first guide seat and the second guide seat respectively, a transverse connecting plate fixedly mounted on the output end of the hydraulic cylinder, a rack plate vertically fixedly mounted on the outer end of the transverse connecting plate, and a gear meshing with the edge of the rack plate and fixedly connected to the outer end of the rotating shaft.

[0007] Preferably, the rotating shaft includes a concave mounting base, a connecting rod, and a rotating shaft. The two concave mounting bases are respectively fixedly disposed on the edges of the first bracket and the second bracket. The rotating shaft is laterally rotatably disposed on the concave mounting base. One end of the connecting rod is located inside the concave mounting base and is fixedly connected to the outer wall of the rotating shaft. The other ends of the two connecting rods are respectively fixedly connected to the edges of the first cover plate and the second cover plate.

[0008] Preferably, when the output ends of the two hydraulic cylinders are extended to their final state, the first cover plate and the second cover plate respectively cover the openings of the first bracket and the second bracket; when the output ends of the two hydraulic cylinders are retracted to their final state, the first cover plate and the second cover plate are respectively located perpendicular to the edges of the first bracket and the second bracket.

[0009] Preferably, the outer wall of the first cover plate has a circular hole, and the protruding part of the first bracket extends outward through the circular hole.

[0010] Preferably, the first guide seat is located below the second guide seat.

[0011] Preferably, the first guide seat and the second guide seat are slidably mounted on the guide rail, and the first guide seat and the second guide seat are driven by hydraulic push rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When the spindle head on either the first or second bracket is working, the corresponding rotating component drives the hydraulic cylinder to extend, causing the connected rack plate to move upward. This drives the drive gear to rotate 90° counterclockwise, causing one end of the first or second cover plate, which is perpendicular to one side, to rotate 90° and overlap, covering the top of the first or second bracket. This covers the spindle head bracket when it is not in use, preventing dust from entering and affecting the placement of the spindle head. It also avoids the phenomenon of not being able to install the spindle head when it is automatically reassembled.

[0014] 2. When this utility model is in use, the inner cavity height of the first cover plate and the second cover plate is higher than the height of the two vertical spindle heads placed in the first bracket and the second bracket respectively. When the second cover plate 4 covers the second bracket, its height position does not contact the first guide seat, and will not affect the movement of the second bracket. It can cover and protect the spindle head when it is placed. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a five-sided gantry machining center, including a column 1 and a bracket moving assembly 2. The bracket moving assembly 2 includes a first guide seat 21 and a second guide seat 22. A first bracket 3 is fixedly installed on the top of the first guide seat 21, and a second bracket 4 is fixedly installed on the top of the second guide seat 22. A first cover plate 31 is hinged above the first bracket 3, and a second cover plate 41 is hinged above the second bracket 4. A rotating shaft 6 is provided on the edge of the first bracket 3 for rotating one end of the first cover plate 31 with a base point. A rotating shaft 6 is provided on the edge of the second bracket 4 for rotating one end of the second cover plate 41 with a base point. Rotating assemblies 5 for driving the first cover plate 31 and the second cover plate 41 to rotate are respectively provided on the edges of the first guide seat 21 and the second guide seat 22.

[0025] The rotating assembly 5 includes a hydraulic cylinder 51 fixedly mounted on the first guide seat 21 and the second guide seat 22 respectively, a transverse connecting plate 52 fixedly mounted on the output end of the hydraulic cylinder 51, a rack plate 53 vertically fixedly mounted on the outer end of the transverse connecting plate 52, and a gear 54 meshing with the edge of the rack plate 53 and fixedly connected to the outer end of the rotating shaft 6.

[0026] When the spindle head on either the first bracket 3 or the second bracket 4 is working, the hydraulic cylinder 51 is extended by the corresponding rotating component 5, causing the connected rack plate 53 to move upward, which drives the drive gear 54 to rotate 90° counterclockwise, causing one end of the first cover plate 31 or the second cover plate 41, which is perpendicular to one side, to rotate 90° and overlap to cover the top of the first bracket 3 or the second bracket 4. This can cover the spindle head bracket when it is not in use to prevent dust from entering and affecting the placement of the spindle head, thus avoiding the phenomenon that the spindle head cannot be installed when it is automatically reassembled. The inner height of the first cover plate 31 and the second cover plate 41 is set at a distance that can cover the spindle head on the bracket. At the same time, it can cover the spindle head placed on the bracket to prevent dust from falling on the spindle head and affecting the machining accuracy of the spindle head. The distance when the first bracket 3 is covered by the first cover plate 31 will not touch the second guide seat 22 above, so as not to affect the automatic movement and replacement of the spindle head on the first bracket 3 and the second bracket 4.

[0027] More preferably, the rotating shaft 6 includes a concave mounting base 61, a connecting rod 62, and a rotating shaft 63. The two concave mounting bases 61 are respectively fixedly disposed on the edges of the first bracket 3 and the second bracket 4. The rotating shaft 63 is laterally rotatably disposed on the concave mounting base 61. One end of the connecting rod 62 is located inside the concave mounting base 61 and is fixedly connected to the outer wall of the rotating shaft 63. The other ends of the two connecting rods 62 are respectively fixedly connected to the edges of the first cover plate 31 and the second cover plate 41.

[0028] Two concave mounting bases 61 are respectively connected to the edges of the first bracket 3 and the second bracket 4. A rotating shaft 63, which is laterally rotatable through the concave mounting base 61, is located on the concave mounting base and is used to support the rotation of the connecting rod 62. The two connecting rods 62 are respectively fixedly connected to the first cover plate 31 and the second cover plate 41 and are used to drive the first cover plate 31 and the second cover plate 41 to rotate.

[0029] More preferably, when the output ends of the two hydraulic cylinders 51 are extended to the final state, the first cover plate 31 and the second cover plate 41 respectively cover the openings of the first bracket 3 and the second bracket 4; when the output ends of the two hydraulic cylinders 51 are retracted to the final state, the first cover plate 31 and the second cover plate 41 are respectively located perpendicular to the edges of the first bracket 3 and the second bracket 4.

[0030] The extension and retraction distance of the two hydraulic cylinders is set to 51, which can be easily operated using the control buttons.

[0031] In a further preferred embodiment, the outer wall of the first cover plate 31 is provided with a round hole, and the protruding part of the first bracket 3 extends outward through the round hole;

[0032] The circular hole provided on the first cover plate 31 is used to reduce the height of the first cover plate 31 by passing through the protruding part of the tip of the vertical spindle head, so that the first bracket 3 and the first cover plate 31 can move under the first guide seat 21.

[0033] More preferably, the first guide seat 21 and the second guide seat 22 are slidably mounted on the guide rail, and the first guide seat 21 and the second guide seat 22 are driven by hydraulic push rods.

[0034] The bracket moving assembly 2 is driven by a simple hydraulic push rod, which is used to push the first bracket 3 and the second bracket 4 to move towards the main shaft head mounting position of the column 1.

[0035] A specific application of this embodiment is as follows: When it is necessary to replace the upper horizontal spindle head, the second bracket 4 is moved to the spindle head mounting position of the column 1, and the horizontal spindle head is installed through the original mounting mechanism by moving downward through the mounting position of the column 1. After installation, the second bracket 4 is moved to its original position and away from the processing position of the column 1. The second bracket 4 is covered by the drive rotation component 5. When replacing the vertical spindle head, firstly, the spindle head mounting position of the column 1 is restored to the position for replacing the spindle head. The rotation component 5 makes the second cover plate 41 perpendicular to the second bracket 4. The second bracket 4 is moved to the spindle head replacement position. The spindle head mounting part on the column 1 moves downward. The second cover plate 41 is set so that it does not contact the spindle head mounting position of the column 1 when it is perpendicular, and does not affect the placement of the spindle head in the second bracket 4. Then the second bracket 4 is restored to its original position, and the first bracket 3 is driven to move to the spindle head mounting position of the column 1.
