Description

Technical Field

[0001] This utility model relates to the technical field of horizontal machining centers, specifically a horizontal machining center with tool magazine and foot support. Background Technology

[0002] A horizontal machining center is a highly automated CNC machine tool that integrates multiple machining functions such as milling, drilling, tapping, and boring. Its core feature is that the spindle axis is parallel to the worktable. This design minimizes the impact of gravity on the workpiece during machining, making it particularly suitable for machining multiple surfaces of complex parts such as box-shaped and shell-shaped parts. It has the advantages of high precision, high efficiency, and high flexibility. The tool magazine is the core component of the automatic tool changer in a horizontal machining center, mainly used for storing, managing, and automatically changing the tools required for machining.

[0003] In traditional horizontal machining centers, the tool magazine is usually directly fixed to the machine bed or column, lacking independent support. When changing tools, the vibration of the robotic arm is directly transmitted to the bed, causing the whole machine to vibrate. Furthermore, the tool magazine may experience a shift in the center of gravity when switching between round tools due to uneven tool weights, such as the different weights of long and heavy tools, which can exacerbate the wear of the disc tool transmission components. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a horizontal machining center with tool magazine foot support, which has advantages such as improved stability of the tool magazine and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a horizontal machining center with tool magazine foot support, comprising a horizontal machining center body, wherein the horizontal machining center body includes a bed, a machining mechanism, a track-type tool changer, and a disc-type tool magazine, the machining mechanism is fixedly installed in the central area of ​​the upper surface of the bed, and the track-type tool changer is fixedly installed on one side of the machining mechanism; A vertical frame is fixedly installed on the upper surface of the machine bed by bolts. The vertical frame is located on one side of the machining mechanism. A column is slidably inserted into the interior of the vertical frame along its height direction. A bearing component is fixedly installed in the central area of ​​the upper end of the column. An arc-shaped bearing plate is fixedly connected to the circumference of the disc-type tool magazine. An insert plate is fixedly connected to the arc-shaped surface of the arc-shaped bearing plate. Both sides of the bottom end of the insert plate are provided with slots. Two concave rubber sleeves are fixedly installed inside the two slots. The inside of the two rubber sleeves is provided with a stop block that matches the shape of the slot. Each stop block is fixedly connected to the bearing component by bolts on one side of the arc-shaped bearing plate. Two symmetrically arranged damping alloy brackets are fixedly connected to the upper surface of the bearing component and are in contact with the insert plate. Rubber pads are provided between the two damping alloy brackets and the arc-shaped bearing plate.

[0006] Furthermore, both of the aforementioned damping alloy supports have a diamond-shaped structure, and the acute-angled ends of both supports are in contact with the insert plate and the load-bearing component.

[0007] The above scheme allows for the concentration of stress at the acute-angled ends of the diamond-shaped structure, improving the damping alloy bracket's sensitivity to vibration and its absorption effect. At the same time, the multi-angle force distribution enhances the structure's rigidity and fatigue resistance, and better stabilizes the connection between the insert plate and the load-bearing component.

[0008] Furthermore, a set of connecting plates is hinged to one side of the arc-shaped bearing plate and the bearing member, and a transmission member is hinged between every two connecting plates. The two transmission members are located on both sides of the insert plate, and a damper is hinged between the two transmission members and the damping alloy bracket.

[0009] Through the above scheme, the damper can consume vibration energy through its own damping characteristics when the disc tool magazine vibrates, further enhancing the vibration reduction performance of the entire tool magazine support structure, reducing the impact of vibration on the disc tool magazine, and thus ensuring the tool changing accuracy of the machining center.

[0010] Furthermore, a rubber pad is fixedly installed in the central area of ​​the inner bottom wall of the bearing member, and the insert plate contacts the central area of ​​the rubber pad.

[0011] The above solution provides elastic support for the insert plate and forms a buffer layer in the vertical direction, effectively absorbing the axial vibration generated when the tool magazine rotates, while preventing direct contact between metal parts, which can cause noise and wear.

[0012] Furthermore, an auxiliary fixing component is fixedly installed on the side of the machining mechanism by bolts, and a rubber ring is interference-fitted between the inner circumferential surface of the auxiliary fixing component and the disc-type tool magazine.

[0013] Through the above scheme, the rubber ring forms a radial flexible constraint through interference fit, which can not only limit the radial runout of the disc tool magazine, but also absorb the impact vibration generated during tool exchange through elastic deformation, thereby improving the positioning stability of the tool magazine.

[0014] Furthermore, the rubber ring has an inverted L-shaped structure, and one side of the rubber ring is in contact with the disc-shaped tool magazine. One side of the auxiliary fixing member has an L-shaped structure opposite to that of the rubber ring and is in contact with the rubber ring, which is used to limit the rubber ring.

[0015] Through the above scheme, the L-shaped bidirectional mating structure forms a limiting effect, and the deformation point of the rubber ring can simultaneously buffer radial and axial vibrations. The reverse L-shaped design ensures that the rubber ring will not fall off during operation, maintaining a continuous and stable shock absorption effect.

[0016] Furthermore, a set of positioning holes is provided on the corresponding side of the frame and the column, and a screw is threaded between every two positioning holes at the upper end. A reinforcing plate with a triangular structure is fixedly connected to the bottom end of the column.

[0017] The above solution enables adjustable column height by using the positioning hole and screw, meeting the installation requirements of tool magazines of different specifications. The triangular reinforcing plate significantly improves the structural rigidity of the column base, preventing frame deformation caused by long-term vibration and ensuring the stability of the tool magazine's positional accuracy.

[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This horizontal machining center with tool magazine and foot support effectively absorbs and disperses vibrations generated by the tool magazine and machining mechanism through a combined vibration reduction structure consisting of rubber sleeves, rubber pads, damping alloy brackets, and dampers. It also reduces the transmission of vibration between the two, minimizing the impact of vibration on machining accuracy and improving the stability of equipment operation. The arc-shaped bearing plate and rubber base pad work together to form an elastic support structure, effectively absorbing axial vibration and preventing wear and noise caused by direct contact between metal parts. The interference fit of the rubber ring provides radial flexibility, limiting the radial runout of the tool magazine and absorbing the impact vibration during tool exchange, thus improving the positioning stability of the tool magazine. Its advantage lies in the fact that through axial and radial vibration reduction design, a three-dimensional vibration suppression is formed, capable of simultaneously coping with vibration interference from different directions.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1-5 This embodiment of a horizontal machining center with tool magazine foot support includes a horizontal machining center body 1. The horizontal machining center body 1 includes a bed 101, a machining mechanism 102, a track-type tool changer 103, and a disc-type tool magazine 104. The machining mechanism 102 is fixedly installed in the central area of ​​the upper surface of the bed 101, and the track-type tool changer 103 is fixedly installed on one side of the machining mechanism 102.

[0023] A vertical frame 2 is bolted to the upper surface of the bed 101. The vertical frame 2 is located on one side of the machining mechanism 102. A column 3 is slidably inserted into the interior of the vertical frame 2 along its height direction. A bearing 4 is fixedly installed in the central area of ​​the upper end of the column 3. An arc-shaped bearing plate 5 is fixedly connected to the circumferential surface of the disc tool magazine 104. The arc-shaped bearing plate 5 increases the contact area with the disc tool magazine 104, so that the weight of the disc tool magazine 104 and various forces generated during operation can be more evenly distributed on the arc-shaped bearing plate 5, avoiding excessive local stress that could lead to structural damage. An insert plate 6 is fixedly connected to the arc-shaped surface of the arc-shaped bearing plate 5. Slots are provided on both sides of the bottom end of the insert plate 6. 7. Two concave rubber sleeves 8 are fixedly installed inside the two slots 7. The rubber sleeves 8 can buffer and dampen vibration through their elastic deformation properties, which can reduce the bidirectional vibration generated during the operation of the disc tool magazine 104 and the machining mechanism 102. The two rubber sleeves 8 are provided with abutment blocks 9 that are adapted to the shape of the slots 7. Each abutment block 9 is fixedly connected to the bearing member 4 by bolts on one side of the arc-shaped bearing plate 5. By utilizing the elastic characteristics of the rubber sleeves 8, vibration energy is effectively absorbed and dispersed, reducing the adverse effects of vibration on the disc tool magazine 104 and the machining mechanism 102, improving the stability and reliability of equipment operation, and extending the service life of the equipment.

[0024] Two symmetrically arranged damping alloy brackets 10 are fixedly connected to the upper surface of the bearing component 4 and are in contact with the insert plate 6. Rubber pads 11 are provided between the two damping alloy brackets 10 and the arc-shaped bearing plate 5. The rubber pads 11 can further absorb vibration energy and reduce friction and wear between the damping alloy brackets 10 and the arc-shaped bearing plate 5, thus extending the service life of the component. The damping alloy brackets 10 can convert vibration energy into heat energy and other forms of energy through their special damping characteristics, thereby further reducing the vibration amplitude.

[0025] Both damping alloy supports 10 have a diamond-shaped structure. The acute angle ends of both supports 10 are in contact with the insert plate 6 and the bearing member 4. The damping alloy support 10 is a support structure designed using the characteristics of damping alloy materials. Its function is to effectively suppress vibration, absorb impact, and improve the stability and reliability of equipment operation through the energy dissipation mechanism inside the material. The acute angle end design of the diamond-shaped structure can concentrate stress, improve the sensitivity and absorption effect of the damping alloy support 10 to vibration, and at the same time, the multi-angle force distribution enhances the rigidity and fatigue resistance of the structure, and better stabilizes the connection between the insert plate 6 and the bearing member 4.

[0026] A set of connecting plates 12 is hinged to one side of the arc-shaped bearing plate 5 and the bearing member 4. A transmission member 13 is hinged between every two connecting plates 12. The two transmission members 13 are located on both sides of the insert plate 6. A damper 14 is hinged between the two transmission members 13 and the damping alloy bracket 10. When the disc tool magazine 104 vibrates, the damper 14 can consume the vibration energy through its own damping characteristics, further enhance the vibration reduction performance of the entire tool magazine support structure, reduce the impact of vibration on the disc tool magazine 104, and thus ensure the tool changing accuracy of the machining center. A rubber base pad 15 is fixedly installed in the central area of ​​the inner bottom wall of the bearing member 4. The insert plate 6 contacts the central area of ​​the rubber base pad 15. The setting of the rubber base pad 15 can provide elastic support for the insert plate 6 and form a buffer layer in the vertical direction, effectively absorbing the axial vibration generated when the tool magazine rotates, while preventing the metal parts from directly contacting each other and generating noise and wear.

[0027] An auxiliary fixing component 16 is bolted to the side of the machining mechanism 102. A rubber ring 17 is interference-fitted between the inner circumferential surface of the auxiliary fixing component 16 and the disc-type tool magazine 104. The rubber ring 17 forms a radial flexible constraint through the interference fit, which can limit the radial runout of the disc-type tool magazine 104 and absorb the impact vibration generated during tool exchange through elastic deformation, thereby improving the positioning stability of the tool magazine. The rubber ring 17 has an inverted L-shaped structure, and one side of the rubber ring 17 is in contact with the disc-type tool magazine 104. One side of the auxiliary fixing component 16 has an L-shaped structure opposite to that of the rubber ring 17 and is in contact with the rubber ring 17, which is used to limit the rubber ring 17. The L-shaped bidirectional fit structure forms a limiting effect. The deformation point of the rubber ring 17 can buffer both radial and axial vibrations at the same time. The reverse L-shaped design ensures that the rubber ring 17 will not fall off during operation, maintaining a continuous and stable shock absorption effect.

[0028] A set of positioning holes 18 are provided on the corresponding side of the frame 2 and the column 3. A screw 19 is threaded between every two positioning holes 18 at the upper end. A triangular reinforcing plate 20 is fixedly connected to the bottom of the column 3. The cooperation between the positioning holes 18 and the screw 19 enables the column 3 to be fixedly height-adjustable, meeting the installation requirements of tool magazines of different specifications. The triangular reinforcing plate 20 significantly improves the structural rigidity of the bottom of the column 3, prevents frame deformation caused by long-term vibration, and ensures the stability of the tool magazine's positional accuracy.

[0029] The working principle of the above embodiment is as follows: When the processing mechanism 102 is working, the vibration generated by the processing mechanism 102 will be transmitted to the bearing member 4 through the upright frame 2 and the upright column 3. Since the bearing member 4 and the insert plate 6 are provided with rubber base pad 15 and rubber sleeve 8, there will be no hard contact between the bearing member 4 and the insert plate 6. The rubber base pad 15 and the rubber sleeve 8 can absorb vibration, thereby reducing the vibration transmission between the two. The auxiliary fixing member 16 and the rubber ring 17 can not only help fix the disc-type tool magazine 104, but also can be used to fix the disc-type tool magazine 104 through the elasticity of the rubber ring 17. The deformation characteristics reduce the vibration transmitted to the disc tool magazine 104. The vibration generated by the machining mechanism 102 and the disc tool magazine 104 is synchronously transmitted to the two connecting plates 12, and then transmitted to the damper 14 through the corresponding transmission component 13 of the connecting plate 12. The damper 14 can absorb the vibration generated by the disc tool magazine 104 and the machining mechanism 102, thereby suppressing the occurrence of adverse conditions such as positional displacement of the disc tool magazine 104 and tool loosening caused by vibration, so that the disc tool magazine 104 can remain stable and ensure the accuracy and quality of the entire machining process.
