Description

Technical Field

[0001] The present application belongs to the technical field of workpiece processing, and specifically relates to a moving beam type machining center. Background Art

[0002] The machining center is developed from the CNC milling machine. The biggest difference between it and the CNC milling machine is that the machining center has the ability to automatically switch machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in one clamping to achieve multiple machining functions.

[0003] At present, the machining center includes a bed and a crossbeam arranged on the top of the bed, and a spindle mechanism is arranged on the crossbeam, and the crossbeam can slide along the length direction of the bed to drive the spindle mechanism to process different positions of the workpiece. However, since the crossbeam can move along the length direction of the bed, it is necessary to set a thick support beam on the top of the bed to ensure the support effect of the crossbeam and avoid the top wall of the support beam from sinking downward; however, due to the thick support beam, the production cost of the machining center is increased, and the weight of the machining center is increased, which makes it more difficult to move the machining center. Utility Model Content

[0004] The present application provides a moving beam type machining center to reduce the production cost of the machining center, reduce the weight of the machining center and achieve the effect of facilitating the movement of the machining center.

[0005] The technical solution adopted in this application is:

[0006] A movable beam machining center includes a bed, a crossbeam slidably connected to the top of the bed, and a spindle mechanism arranged on the crossbeam. The top of the bed has a support beam, the support beam is hollow inside, and a support member is arranged inside the support beam for supporting its own top wall.

[0007] By adopting the above-mentioned technical scheme, since the support beam in the present application is hollow inside and a support member for supporting the top wall of the support beam is arranged inside the support beam, the movable beam type machining center in the present application can use a support beam with a smaller wall thickness, so as to reduce the weight of the support beam while ensuring the structural strength of the support beam, thereby reducing the weight and production cost of the movable beam type machining center, so as to achieve the effect of facilitating the staff to move the movable beam type machining center, and at the same time, since the wall thickness of the support beam used is reduced, the production cost of the movable beam type machining center is reduced.

[0008] Optionally, a plurality of support members are arranged along the length direction of the support beam, and each of the support members is arranged parallel to the vertical direction.

[0009] By adopting the above technical solution, since the support member is arranged parallel to the vertical direction, the supporting effect of the support member on the top wall of the support beam is increased, thereby further increasing the structural strength of the support beam. At the same time, multiple support members are arranged along the length direction of the support beam, thereby increasing the supporting points of the support member on the support beam, thereby further increasing the structural strength of the support beam.

[0010] Optionally, each of the support members includes two cross-arranged support plates.

[0011] By adopting the above technical solution, since the support member includes two cross-arranged support plates, the supporting points of the support member on the support beam are further increased, thereby further increasing the structural strength of the support beam. At the same time, the support member can be arranged uninterruptedly along the length direction of the support beam to ensure the supporting effect of multiple pairs of support members on the support beam.

[0012] Optionally, each of the support plates is provided with a weight-reducing hole to reduce the weight of the support plate.

[0013] By adopting the above technical solution, since the support plate is provided with weight-reducing holes, the weight of the support plate is reduced while ensuring the structural strength of the support plate, so as to further increase the weight of the moving beam type machining center, thereby further achieving the effect of facilitating the movement of the moving beam type machining center.

[0014] Optionally, operation holes are provided on opposite sides of the support beam to reduce the weight of the support beam.

[0015] By adopting the above technical solution, since operation holes are provided on the opposite sides of the support beam, on the one hand, the weight of the support beam is reduced while ensuring the structural strength of the support beam. On the other hand, the provision of the operation holes can facilitate the staff to assemble the support parts, thereby reducing the difficulty of assembling the support parts, thereby improving the production efficiency of the moving beam type machining center, and further reducing the production cost of the moving beam type machining center.

[0016] Optionally, a sealing cover for sealing the operating hole is provided at the operating hole.

[0017] By adopting the above technical solution, a sealing cover is provided at the operation position to seal the operation hole to prevent dirt from entering the support beam through the operation hole, thereby ensuring the cleanliness of the moving beam type machining center. At the same time, the sealing cover can also cover the internal structure of the support beam to increase the appearance quality of the moving beam type machining center. In addition, it can also prevent the staff from accidentally putting their hands into the operation hole, which may cause harm to the staff.

[0018] Optionally, the bed has a support column located at the bottom of the support beam, and the interior of the support column is hollow.

[0019] By adopting the above technical solution, since the support column is extended in the vertical direction and the interior of the support column is hollow, the weight of the bed is further reduced while ensuring the structural strength of the support column, thereby further reducing the weight of the moving beam type machining center, thereby further facilitating the staff to move the moving beam type machining center. At the same time, compared with the support column being a solid structure, the production cost of the moving beam type machining center is also reduced.

[0020] Optionally, a reinforcement column is arranged on the outer side of the support column, and the interior of the reinforcement column is hollow.

[0021] By adopting the above technical solution, since a reinforcing column is arranged on the outside of the support column, the stability of the support column is increased, so as to increase the stability of the bed, thereby ensuring the working stability of the moving beam type machining center, and the inner hollow setting of the reinforcing column can reduce the weight of the reinforcing column, so as to reduce the weight of the bed, thereby ensuring the effect of facilitating the movement of the moving beam type machining center.

[0022] Optionally, a fixing plate is provided at the bottom of the support column, and a connecting pipe with a pipe opening facing the side of the support column is provided between the fixing plate and the reinforcement column.

[0023] By adopting the above technical scheme, after the moving beam type machining center is placed at the set position, in order to increase the stability of the moving beam type machining center, it is necessary to use expansion bolts to fix the bed. Since a connecting pipe with the pipe mouth facing the side of the support column is provided between the fixing plate and the reinforcing column, when fixing the bed, the expansion bolt can be passed through the connecting pipe and the fixing plate and inserted into the ground, so that the internal space of the connecting pipe is provided for the installation of the expansion bolt, so as to achieve the effect of facilitating the fixation of the bed and avoid the need to extend the fixing plate toward the outside of the reinforcing column, so as to further reduce the production cost and weight of the bed. In addition, the insertion of the expansion bolts in the connecting pipe and the fixing plate can also increase the fixing effect of the expansion bolts on the bed.

[0024] Optionally, a reinforcing sheet parallel to the vertical direction is provided in the connecting pipe to increase the pressure that the connecting pipe can withstand in the vertical direction.

[0025] By adopting the above technical solution, since a reinforcement plate parallel to the vertical direction is provided in the connecting tube, the reinforcement plate can support the top wall of the connecting tube, thereby increasing the pressure that the connecting tube can withstand in the vertical direction, so as to ensure the supporting effect of the connecting tube on the reinforcement column, thereby ensuring the supporting effect of the reinforcement column on the supporting column, and then increasing the structural strength of the bed.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0027] 1. The moving beam type machining center in the present application includes a bed, a crossbeam slidably connected to the top of the bed, and a spindle mechanism arranged on the crossbeam. The top of the bed is provided with a support beam, the interior of the support beam is hollow, and the interior of the support beam is provided with a support member for supporting its own top wall. As a result, the moving beam type machining center in the present application can use a support beam with a smaller wall thickness, so as to reduce the weight of the support beam while ensuring the structural strength of the support beam, thereby reducing the weight and production cost of the moving beam type machining center, so as to achieve the effect of facilitating the staff to move the moving beam type machining center. At the same time, since the wall thickness of the support beam used is reduced, the production cost of the moving beam type machining center is reduced.

[0028] 2. The support members in the present application are arranged in plurality along the length direction of the support beam, and each support member is arranged parallel to the vertical direction, thereby increasing the supporting effect of the support member on the top wall of the support beam, thereby further increasing the structural strength of the support beam. At the same time, the support members are arranged in plurality along the length direction of the support beam, thereby increasing the supporting points of the support members on the support beam, so as to further increase the structural strength of the support beam.

[0029] 3. Each support member in the present application includes two cross-arranged support plates, which further increases the supporting points of the support member on the support beam, thereby further increasing the structural strength of the support beam, and at the same time enables the support member to be arranged uninterruptedly along the length direction of the support beam to ensure the supporting effect of multiple pairs of support members on the support beam.

In this embodiment, the support member 4 is a plate-like structure with a C-shaped cross-sectional shape, that is, the support member 4 includes a web and wing plates arranged on both sides of the web, the web is fixedly connected to the top wall of the support beam 11 so that the web reinforces the support of the top wall of the support beam 11, and the two wing plates are respectively fixedly connected to the two side walls of the support beam 11 so that the wing plates reinforce the support of the side walls of the support beam 11, thereby increasing the structural strength of the support beam 11.

[0049] Implementation method 2. In this implementation method, refer to Figure 2 , Figure 3 and Figure 4Multiple support members 4 are arranged along the length direction of the support beam 11 to increase the supporting points of the support members 4 on the support beam 11, thereby further increasing the structural strength of the support beam 11, and each support member 4 is arranged parallel to the vertical direction, thereby increasing the supporting effect of the support member 4 on the top wall of the support beam 11, thereby further increasing the structural strength of the support beam 11.

[0050] In this embodiment, the structure of the support member 4 is not specifically limited, and it can adopt any one of the following embodiments:

[0051] Embodiment 1, in this embodiment, refer to Figure 4 and Figure 5 Each support member 4 includes two cross-arranged support plates 41, which further increases the supporting points of the support member 4 on the support beam 11, thereby further increasing the structural strength of the support beam 11, and at the same time enables the support member 4 to be continuously arranged along the length direction of the support beam 11 to ensure the supporting effect of the support member 4 on the support beam 11.

[0052] Preferably, the two support sheets 41 are disposed perpendicular to each other, that is, the two support sheets 41 together form a cross-shaped structure.

[0053] Further, see Figure 5 Each support plate 41 is provided with a weight-reducing hole 411 to reduce the weight of the support plate 41. Then, under the premise of ensuring the structural strength of the support plate 41, the weight of the support plate 41 is reduced to further increase the weight of the moving beam type machining center, thereby further achieving the effect of facilitating the movement of the moving beam type machining center.

[0054] Embodiment 2. In this embodiment, the support member 4 includes a center plate and extension plates arranged on both sides of the center plate.

At the same time, it can also achieve the effect of facilitating the assembly of the support member 4, thereby improving the assembly efficiency of the support member 4.

[0055] In a preferred embodiment, referring to Figure 2 , Figure 3 and Figure 4 Operation holes 111 are provided on the opposite sides of the support beam 11, thereby reducing the weight of the support beam 11 while ensuring the structural strength of the support beam 11. On the other hand, the provision of the operation holes 111 can facilitate the staff to assemble the support member 4, thereby reducing the difficulty of assembling the support member 4, thereby improving the production efficiency of the movable beam type machining center, and further reducing the production cost of the movable beam type machining center.

[0056] Further, see Figure 2A sealing cover 112 is provided at the operating hole 111 for sealing the operating hole 111 to prevent dirt from entering the support beam 11 through the operating hole 111, so as to ensure the cleanliness of the moving beam type machining center.

In addition, it can also prevent the staff from accidentally putting their hands into the operating hole 111, which may cause harm to the staff.

[0057] The present application does not specifically limit the structure of the sealing cover 112.

Since a connecting pipe 123 with the pipe mouth facing the side of the support column 12 is provided between the fixing plate 122 and the reinforcing column 121, when fixing the bed 1, the expansion bolt can be passed through the connecting pipe 123 and the fixing plate 122 and penetrated into the ground, so that the internal space of the connecting pipe 123 is provided for the installation of the expansion bolt, so as to achieve the effect of facilitating the fixation of the bed 1, and at the same time avoid the need to extend the fixing plate 122 toward the outside of the reinforcing column 121, so as to further reduce the production cost and weight of the bed 1. In addition, the penetration of the expansion bolts through the connecting pipe 123 and the fixing plate 122 can also increase the fixing effect of the expansion bolts on the bed 1.

[0063] Further, refer to Figure 1 and Figure 6 A reinforcing sheet 124 parallel to the vertical direction is provided in the connecting tube 123, that is, the reinforcing sheet 124 is arranged perpendicular to the axis of the connecting tube 123, so that the reinforcing sheet 124 can support the top wall of the connecting tube 123, thereby increasing the pressure that the connecting tube 123 can withstand in the vertical direction, so as to ensure the supporting effect of the connecting tube 123 on the reinforcing column 121, thereby ensuring the supporting effect of the reinforcing column 121 on the supporting column 12, thereby increasing the structural strength of the bed 1, and the reinforcing sheet 124 is located in the middle position of the length direction of the connecting tube 123, so as to ensure the supporting effect of the reinforcing sheet 124 on the connecting tube 123 while achieving the effect of facilitating the use of expansion bolts to fix the bed 1.

[0064] The present application does not make any specific limitation on the structure of the crossbeam 2. Preferably, the interior of the crossbeam 2 is hollow, that is, the crossbeam 2 is a tubular structure, and a support member 4 is also provided inside the crossbeam 2 to reduce the weight of the crossbeam 2, thereby reducing the required thickness of the support beam 11, so as to further reduce the weight of the support beam 11, thereby further facilitating the movement of the movable beam type machining center.

[0065] In a preferred embodiment, referring to Figure 7 A storage tube 21 is passed through the crossbeam 2. The length direction of the storage tube 21 is horizontally arranged and perpendicular to the length direction of the crossbeam 2. At the same time, the two pipe openings of the storage tube 21 are respectively located on the two opposite sides of the crossbeam 2, so that the staff can place knives or other tools in the storage tube 21 to achieve the effect of facilitating the storage of knives and tools.
