Description

Technical Field

[0001] This application relates to the field of laser cutting technology, specifically to a processing platform and a laser cutting machine. Background Technology

[0002] Laser cutting machines are widely used in various manufacturing industries such as aerospace, automotive, and shipbuilding, undertaking the task of processing various raw materials. Some large parts to be cut require the use of flat fixtures for support and fixation during the cutting process.

[0003] To achieve assembly line production, it is necessary to efficiently move flat fixtures into and out of the working position, and each time they are moved in, the flat fixtures need to be precisely positioned in the working position to ensure production quality. Laser cutting machines provided in related technologies are difficult to meet this requirement. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a processing platform and laser cutting machine capable of rapid transfer and high-precision positioning of flat tooling.

[0005] The first aspect of this application provides a processing platform for use in a laser cutting machine. The processing platform includes: a base; a flat fixture for placement on the top side of the base and for carrying a workpiece to be cut; a transfer member for moving the flat fixture into or out of the base; a carrier member disposed on the base for forming a sliding fit between the flat fixture and the base; and a pushing device disposed on the base for pushing the flat fixture relative to the base to a working position.

[0006] In some embodiments, the base forms a limiting surface, which abuts against the flat plate fixture to constrain the flat plate fixture in the working position.

[0007] In some embodiments, the pushing device includes a first pushing member and a second pushing member, the first pushing member being used to push the flat fixture to move along a first direction, and the second pushing member being used to push the flat fixture to move along a second direction, wherein the first direction and the second direction are perpendicular to the height direction of the processing platform; the limiting surface includes a first limiting surface perpendicular to the first direction and a second limiting surface perpendicular to the second direction.

[0008] In some embodiments, the flat fixture includes a plate-shaped body and a first abutting portion and a second abutting portion disposed on the plate-shaped body. The first abutting portion is used to abut against the first limiting surface, and the second abutting portion is used to abut against the second limiting surface. At least one of the first abutting portion and the second abutting portion is capable of forming a sliding fit with the corresponding limiting surface.

[0009] In some embodiments, at least one of the first abutting portion and the second abutting portion includes a rotating shaft and a pulley. The rotating shaft protrudes from the surface of the plate-shaped body, and the pulley is connected to the end of the rotating shaft away from the plate-shaped body. The pulley is capable of rotating around the rotating shaft to achieve a sliding engagement with the corresponding limiting surface.

[0010] In some embodiments, the flat tooling further includes a first force-bearing bracket and a second force-bearing bracket protruding from the plate-shaped body, wherein the thrust of the first pusher acts on the first force-bearing bracket and the thrust of the second pusher acts on the second force-bearing bracket.

[0011] In some embodiments, the base includes a first support beam and a second support beam spaced apart along the first direction, the first support beam and the second support beam extending along the second direction, and the first support beam and the second support beam respectively provided with at least one load-bearing member, at least one first pusher member and at least one second pusher member.

[0012] In some embodiments, the processing platform further includes a slide rail, with the first support beam and the second support beam forming a sliding engagement with the slide rail; and / or the processing platform further includes a transfer track, the transfer track being located between the first support beam and the second support beam along the first direction, and the transfer track extending along the second direction, with the transfer component slidingly engaging with the transfer track along the second direction; and / or the transfer component includes a transfer cart and a lifting mechanism disposed on the transfer cart, the lifting mechanism being used to drive the flat tooling to move relative to the transfer cart along the height direction of the processing platform.

[0013] In some embodiments, the support member is fixed to the top surface of the base, and the support member includes a bullseye bearing and / or a caster wheel.

[0014] A second aspect of this application provides a laser cutting machine, which includes the processing platform described in the first aspect of this application.

[0015] In this embodiment, the processing platform and laser cutting machine are equipped with a transfer component to move the flat fixture into or out of the base, thereby enabling rapid transfer of the flat fixture and meeting production efficiency requirements. Furthermore, it is understood that the transfer component cannot directly and accurately position the flat fixture at the working position. Therefore, this embodiment further includes a pushing device to move the flat fixture relative to the base, thus improving the positioning accuracy of the flat fixture. Moreover, as mentioned above, the flat fixture typically has a large volume and weight, and its direct contact with the base generates significant friction, leading to a decrease in the accuracy and speed of the flat fixture's movement relative to the base. Therefore, this embodiment includes a bearing component that enables a sliding fit between the base and the flat fixture, thereby greatly reducing the friction between them and effectively improving the speed and accuracy of the pushing device when moving the flat fixture.

[0016] In summary, the processing platform, laser cutting machine, and control method of this embodiment can achieve rapid turnover of flat tooling and can quickly and accurately position the flat tooling moved into the base. Attached Figure Description

[0032] Laser cutting machines are widely used in various manufacturing industries such as aerospace, automobiles, and shipbuilding, undertaking the task of processing various raw materials. To ensure stable cutting operations, the flat fixture used to support the workpiece to be cut should be fixed in the working position to prevent the flat fixture from moving during the cutting process under the influence of external forces, which could lead to cutting deviations, scrap the workpiece, or even injure workers.

[0033] Flat fixtures used to support and fix workpieces to be cut often have a large volume (e.g., they need to have a support surface of 2m*3m or larger), which makes it difficult to move and position the flat fixtures in actual production, affecting production efficiency and quality.

[0034] In view of this, a first aspect of the present application provides a processing platform for use in a laser cutting machine. The processing platform is used to transfer and position a flat fixture in a position suitable for the laser cutting head of the laser cutting machine to work, so that the laser cutting head can complete the cutting operation on the workpiece to be cut carried on the flat fixture.

[0035] Reference Figure 1 and Figure 2 The processing platform 100 specifically includes a base 110, a flat fixture 120, a transfer component 130, a support component 140, and a pushing device 150. The flat fixture 120 is placed on the top side of the base 110 and is used to support the workpiece to be cut. The transfer component 130 is used to move the flat fixture 120 into or out of the base 110. The support component 140 is fixed to the base 110 and is used to make the flat fixture 120 slide against the base 110. The pushing device 150 is disposed on the base 110 and is used to push the flat fixture 120 relative to the base 110 to the working position.

[0036] The specific structural form of the base 110 is not limited. As an example, the base 110 may include one or more support blocks, support beams, etc. Those skilled in the art can make the settings according to the specific structure of the flat tooling 120.

[0037] The flat fixture 120 is placed on the top side of the base 110 and is used to support the workpiece to be cut. Specifically, the flat fixture 120 refers to a fixture that is generally flat and can provide support and fixation for the workpiece to be cut. More specifically, the top side of the flat fixture 120 forms a support surface for supporting the workpiece to be cut, and the support surface is generally rectangular with dimensions of not less than 1.2m * 1.5m.

[0038] In some examples, refer to Figure 3 The flat fixture 120 includes a plate-shaped body 121, which includes multiple top beams 1211, multiple bottom beams 1212, multiple connecting beams 1213, and multiple support cylinders 1214. The top beams 1211 and bottom beams 1212 are arranged one-to-one along the height direction of the processing platform 100. Each top beam 1211 extends along a first direction and is distributed along a second direction, as do each bottom beam 1212. The connecting beams 1213 extend along the second direction and are distributed along the first direction. Along the second direction, the connecting beams 1213 connect multiple top beams 1211 or multiple bottom beams 1212. It can be understood that here, the top beams 1211, bottom beams 1212, and connecting beams 1213 are connected to form a rectangular frame structure. The support cylinders 1214 extend along the height direction of the processing platform 100. The top end of the support cylinder 1214 is connected to the top beam 1211, and the bottom end is connected to the bottom beam 1212. The support cylinder 1214 includes, but is not limited to, cylinders. The flat fixture 120 in this example has a smaller weight due to its frame structure (compared to flat fixtures 120 in related art that provide the same support area), and has better support performance due to the use of support cylinder 1214.

[0039] There can be multiple flat fixtures 120. In actual use, multiple flat fixtures 120 can be placed sequentially on the top side of the base 110 to realize the assembly line processing of multiple parts to be cut. When there are multiple flat fixtures 120, the structures of the multiple flat fixtures 120 can be the same or different, and there is no restriction on this.

[0040] The transfer component 130 is used to move the flat fixture 120 into or out of the base 110. Here, moving into the base 110 means moving the flat fixture 120 from another position (e.g., the previous station) and placing it on the top side of the base 110, and moving out means moving the flat fixture 120 from the top side of the base 110 to another position (e.g., the next station).

[0041] The specific structural form of the transfer component 130 is not limited, as long as it can carry the flat fixture 120 and drive the flat fixture 120 to move relative to the base 110 to move into or out of the base 110. As an example, the transfer component 130 includes a transfer vehicle, such as an AGV (Automated Guided Vehicle), and as another example, the transfer component 130 includes a robotic arm.

[0042] In practical use, the flat fixture 120 can be moved into the base 110 using the transfer component 130. After cutting is completed, the flat fixture 120 can be moved out of the base 110 using the transfer component 130, and the next flat fixture 120 can be moved into the base 110, thus realizing assembly line production. The number of transfer components 130 can be one or multiple, and those skilled in the art can determine the specific number according to the actual flow requirements of the flat fixture 120, without any limitation.

[0043] The support member 140 is disposed on the base 110. The support member 140 is used to make the flat plate tooling 120 slide with the base 110. The pushing device 150 is disposed on the base 110 and is used to push the flat plate tooling 120 relative to the base 110 to the working position.

[0044] The specific structural form of the support member 140 is not limited, as long as it enables the flat plate tooling 120 to form a sliding fit with the base 110. As an example, the support member 140 can be a structure that forms a sliding fit with the base 110, such as a sliding block or pulley 1222. The flat plate tooling 120 can indirectly achieve a sliding fit with the base 110 through the sliding fit between the support member 140 and the base 110. As another example, the support member 140 can be a structure fixed to the base 110 and having a sliding surface, such as a bullseye bearing or a caster wheel. Taking a bullseye bearing as an example, the bullseye bearing can be fixed to the top surface of the base 110, and the bottom surface of the flat plate tooling 120 can rely on the balls of the bullseye bearing, thereby achieving a sliding fit with the base 110 through the rolling of the balls.

[0045] The specific structural form of the pushing device 150 is not limited, as long as it can push the flat tooling 120 to move relative to the base 110. As an example, the pushing device 150 may include one or more pushing elements, which may be cylinders, hydraulic cylinders, electric cylinders, etc. In the case where the pushing device 150 includes multiple pushing elements, at least some of the multiple pushing elements can be configured to push the flat tooling 120 to move relative to the base 110 in different directions. The specific pushing direction of the pushing elements can be specifically determined by those skilled in the art according to the actual position adjustment requirements of the flat tooling 120.

[0046] In this embodiment, the processing platform 100 includes a transfer component 130 to move the flat fixture 120 into or out of the base 110, thereby enabling rapid transfer of the flat fixture 120 and meeting production efficiency requirements. Furthermore, it can be understood that the transfer component 130 cannot directly and accurately position the flat fixture 120 at the working position. Therefore, this embodiment further includes a pushing device 150 to push the flat fixture 120 relative to the base 110, thus improving the positioning accuracy of the flat fixture 120. Moreover, as mentioned above, the flat fixture 120 typically has a large volume and weight, and its direct contact with the base 110 generates significant friction, leading to a decrease in the accuracy and speed of the flat fixture 120's movement relative to the base 110. Therefore, this embodiment includes a bearing component 140, which enables a sliding fit between the base 110 and the flat fixture 120, thereby greatly reducing the friction between them and effectively improving the speed and accuracy of the pushing device 150 when pushing the flat fixture 120.

[0047] In summary, the processing platform 100 of this embodiment can realize the rapid transfer of the flat tooling 120 and can perform rapid and high-precision positioning of the flat tooling 120 that has been moved into the base 110.

[0048] In some embodiments, refer to Figures 4-6 The base 110 forms a limiting surface, which is used to abut against the flat plate fixture 120 to constrain the flat plate fixture 120 in the working position.

[0049] Here, the limiting surface is specifically set so that the flat tool 120 is in the working position when it abuts against it. In actual use, the pushing device 150 can apply a pushing force to the flat tool 120 so that it abuts against the limiting surface. Then, by maintaining the pushing force applied by the pushing device 150, the flat tool 120 can be constrained in the working position by means of the limiting surface.

[0050] Here, the specific location and orientation of the limiting surface can be determined by those skilled in the art based on the specific working position, the pushing direction of the pusher and its contact position with the flat tooling 120, etc., and there are no restrictions on this.

[0051] In this embodiment, the limiting surface formed on the base 110 can improve the positioning accuracy of the flat tooling 120 and the positional stability of the flat tooling 120 during the processing, thereby further improving the processing quality.

[0052] In some embodiments, still refer to Figures 4-6The pushing device 150 includes a first pushing member 151 and a second pushing member 152. The first pushing member 151 is used to push the flat tooling 120 to move along a first direction, and the second pushing member 152 is used to push the flat tooling 120 to move along a second direction. The first direction and the second direction are perpendicular to the height direction of the processing platform 100. The limiting surface includes a first limiting surface 110a perpendicular to the first direction and a second limiting surface 110b perpendicular to the second direction.

[0053] As an example, the first pusher 151 and the second pusher 152 can have the same structure, differing only in the direction of push. For example, the first pusher 151 and the second pusher 152 can both be one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The number of first pushers 151 can be one or more, and the same applies to second pushers 152. The number of first pushers 151 and the second pushers 152 can be the same or different, without limitation.

[0054] In some examples, there are at least two first pushers 151 and two second pushers 152. When the flat fixture 120 is in the working position, the mounting positions of each first pusher 151 are symmetrically distributed relative to the flat fixture 120, and the mounting positions of each second pusher 152 are also symmetrically distributed relative to the flat fixture 120.

[0055] This configuration helps reduce the possibility that the flat fixture 120 may deflect due to uneven force when the first pusher 151 and the second pusher 152 push the flat fixture 120 to move.

[0056] In actual use, the first pusher 151 and the second pusher 152 can push the flat fixture 120 to move simultaneously, or the first pusher 151 can first push the flat fixture 120 to abut against the first limiting surface 110a, and then the second pusher 152 can push the flat fixture 120 to abut against the second limiting surface 110b. Those skilled in the art can determine this according to actual use requirements.

[0057] In this embodiment, by setting the first pusher 151 and the second pusher 152, the flat tool 120 can be pushed to move relative to the base 110 in two directions, which helps to further improve the positioning accuracy of the flat tool 120. In addition, it helps to reduce the motion accuracy requirements of the transfer member 130 and the accuracy requirements of the flat tool 120 placed on the transfer member 130 (when the transfer member 130 places the flat tool 120 on the base 110, it can be offset relative to the working position in both the first and second directions), which helps to further improve the transfer efficiency of the flat tool 120.

[0058] In some embodiments, refer to Figures 3-6The flat tooling 120 specifically includes a plate-shaped body 121 and a first abutting part 122 and a second abutting part 123 disposed on the plate-shaped body 121. The first abutting part 122 is used to abut against a first limiting surface 110a, and the second abutting part 123 is used to abut against a second limiting surface 110b. At least one of the first abutting part 122 and the second abutting part 123 can form a sliding fit with the corresponding limiting surface.

[0059] Here, the first abutting part 122 is provided in a one-to-one correspondence with the first limiting surface 110a, and the second abutting part 123 is provided in a one-to-one correspondence with the second limiting surface 110b. The specific structural form and the position of the first abutting part 122 and the second abutting part 123 are not limited, as long as they abut against the corresponding limiting surface so that the flat tooling 120 is exactly in the working position.

[0060] As an example, the first abutment 122 is disposed on one end face of the plate-shaped body 121 along the second direction, and the second abutment 123 is disposed on the bottom surface of the plate-shaped body 121.

[0061] The specific implementation of the sliding fit between the first abutment 122 and the second abutment 123 and the corresponding limiting surface is not limited. As an example, the first abutment 122 and / or the second abutment 123 may include a pulley 1222, a bullseye bearing, etc., so as to achieve a sliding fit with the corresponding limiting surface.

[0062] In this embodiment, the first abutting part 122 and the second abutting part 123 can both be configured to form a sliding fit with the corresponding limiting surface, or one of the first abutting part 122 and the second abutting part 123 can be configured to form a sliding fit with the corresponding limiting surface, while the other can only abut against the corresponding limiting surface without forming a sliding fit (here, "without forming a sliding fit" specifically means that the two are in direct contact and no structure is provided to reduce friction).

[0063] It is understandable that even when the first pusher 151 and the second pusher 152 push the flat tool 120 to move relative to the base 110 in a synchronized manner, it is difficult to guarantee that the first abutment 122 and the second abutment 123 abut against the corresponding limiting surface at the same time. In other words, it is common for one of the first abutment 122 and the second abutment 123 to abut against the corresponding limiting surface, while the flat tool 120 still needs to move relative to the base 110.

[0064] Therefore, in this embodiment, at least one of the first abutment portion 122 and the second abutment portion 123 is configured to slide against the corresponding limiting surface. Taking the first abutment portion 122 being configured to slide against the first limiting surface 110a as an example, in actual use, the first abutment portion 122 can be abutted against the first limiting surface 110a by means of the first pusher 151, and then the flat fixture 120 can be pushed to move along the second direction by means of the second pusher 152. Since the first abutment portion 122 can slide against the first limiting surface 110a, the friction is low, which can reduce the resistance when the second pusher 152 pushes the flat fixture 120 to move, and also helps to reduce the wear of the first abutment portion 122 and the first limiting surface 110a, thereby reducing the probability of a decrease in positioning accuracy due to wear of the first abutment portion 122 and the first limiting surface.

[0065] In some embodiments, refer to Figure 5 At least one of the first abutting part 122 and the second abutting part 123 includes a rotating shaft 1221 and a pulley 1222. The rotating shaft 1221 protrudes from the surface of the plate-shaped body 121, and the pulley 1222 is connected to the end of the rotating shaft 1221 away from the plate-shaped body 121. The pulley 1222 can rotate around the rotating shaft 1221 to achieve sliding engagement with the corresponding limiting surface.

[0066] Figure 5 Taking the first abutment part 122, which includes a rotating shaft 1221 and a pulley 1222, as an example, the rotating shaft 1221 specifically protrudes from the bottom surface of the plate-shaped body 121 and extends along the height direction of the processing platform 100. The pulley 1222 is disposed at the bottom end of the rotating shaft 1221 and can rotate around the rotating shaft 1221, thereby enabling the first abutment part 122 to form a sliding fit with the first limiting surface 110a along the first direction.

[0067] In this embodiment, this arrangement helps to reduce costs while enabling at least one of the first abutting part 122 and the second abutting part 123 to form a sliding fit with the corresponding limiting surface.

[0068] In some embodiments, refer to Figure 6 A buffer layer is formed on the side of the first abutment portion 122 and / or the second abutment portion 123 that abuts against the limiting surface. The buffer layer formed by the first abutment portion 122 and / or the second abutment portion 123 helps to reduce the impact force when it abuts against the limiting surface, thereby helping to reduce the possibility of deformation of the limiting surface leading to a decrease in positioning accuracy.

[0069] In some embodiments, the plate-shaped body 121 further includes a first force-bearing support 124 and a second force-bearing support 125 protruding from the plate-shaped body 121, the thrust of the first pusher 151 acts on the first force-bearing support 124, and the thrust of the second pusher 152 acts on the second force-bearing support 125.

[0070] The specific structural forms of the first load-bearing support 124 and the second load-bearing support 125 are not limited. For example, refer to... Figure 6 The first force-bearing support 124 includes a first force-bearing plate 1241 and a first reinforcing rib 1242. The first force-bearing plate 1241 is connected to one end face of the plate-shaped body 121 along the second direction. The thickness direction of the first force-bearing plate 1241 is the first direction. The first reinforcing rib 1242 is provided on the side surface of the first force-bearing plate 1241 opposite to the corresponding first pushing member 151. One end of the first reinforcing rib 1242 is connected to the force-bearing plate, and the other end is connected to the plate-shaped body 121. (Refer to...) Figure 7 The second force-bearing support 125 includes a second force-bearing plate 1251 and a second reinforcing rib 1252. The second force-bearing plate 1251 is connected to one end face of the plate-shaped body 121 along the first direction. The thickness direction of the second force-bearing plate 1251 is the second direction. The second reinforcing rib 1252 is provided on the side surface of the second force-bearing plate 1251 opposite to the corresponding second pusher 152. One end of the second reinforcing rib 1252 is connected to the force-bearing plate, and the other end is connected to the plate-shaped body 121. This arrangement helps to improve the structural strength of the first force-bearing support 124 and the second force-bearing support 125.

[0071] In this embodiment, by setting the first force support 124 and the second force support 125, it is helpful to further improve the uniformity of force on the flat tool 120 when the pusher pushes the flat tool 120 to move, thereby improving the force accuracy.

[0072] As an example, there are at least two first force-bearing supports 124, each protruding from one of the two end faces of the plate-shaped body 121 along the second direction. There are at least two second force-bearing supports 125, each protruding from one of the opposite end faces of the plate-shaped body 121 along the first direction. The first pusher 151 and the second pusher 152 are provided in a one-to-one correspondence with the first force-bearing supports 124 and the second force-bearing supports 125.

[0073] In some embodiments, refer to Figure 2 The base 110 includes a first support beam 111 and a second support beam 112 spaced apart along a first direction. The first support beam 111 and the second support beam 112 extend along a second direction. The first support beam 111 and the second support beam 112 are respectively provided with at least one bearing member 140, at least one first push member 151 and at least one second push member 152.

[0074] In this embodiment, by configuring the base 110 to include a first support beam 111 and a second support beam 112 spaced apart, it is possible to provide stable support for the flat tooling 120 while reducing the area of ​​the base 110 and the number of load-bearing components 140 that need to be installed on the base 110, thereby reducing costs.

[0075] In some embodiments, refer to Figure 2 The first support beam 111 is provided with two first pushing members 151 and two second pushing members 152. The two first pushing members 151 are respectively located at opposite ends of the first support beam 111 along the second direction, and the two second pushing members 152 are located between the two first pushing members 151, with the two second pushing members 152 and the two first pushing members 151 spaced apart along the second direction. The top surface of the first support beam 111 is provided with a plurality of bearing members 140 distributed along the second direction. The second support beam 112 and related structures adopt a similar arrangement, which will not be described in detail here.

[0076] In this embodiment, it helps to reduce the probability of deflection when the pushing device 150 pushes the flat tool 120 to slide relative to the base 110, and helps to distribute the weight of the flat tool 120 relatively evenly among each bearing member 140. On the one hand, it helps to improve the service life of the bearing member 140, and on the other hand, it helps to further reduce friction.

[0077] In some embodiments, refer to Figure 1 and Figure 2 The processing platform 100 also includes a slide rail 160, and the first support beam 111 and the second support beam 112 form a sliding fit with the slide rail 160. It is understood that in actual processing, there may be a need to move the workpiece. However, directly moving the flat fixture 120 on the base 110 would result in positioning accuracy issues. Therefore, in this embodiment, the base 110 is configured to slide along the slide rail 160. Thus, after the flat fixture 120 is positioned on the base 110, there is no need to move the flat fixture 120 again during processing; only the base 110 needs to be slid along the slide rail 160, thus meeting the positioning accuracy requirements of the flat fixture 120.

[0078] In this embodiment, the first support beam 111 and the second support beam 112 are specifically formed as beam-shaped structures extending along the second direction. The first support beam 111 and the second support beam 112 can slide and cooperate with the slide rail 160 along the first direction and / or the second direction. Those skilled in the art can determine the specific configuration according to actual processing requirements, and there are no restrictions on this.

[0079] In some embodiments, the processing platform 100 further includes a transfer track located between the first support beam 111 and the second support beam 112 along a first direction, and the transfer track extends along a second direction, with the transfer member 130 slidingly engaging with the transfer track along the second direction.

[0080] In this embodiment, a transfer track is provided for sliding cooperation with the transfer component 130. This helps to improve the motion accuracy of the transfer component 130, thereby helping to reduce the deviation between the flat tooling 120 and the working position when it is placed on the base 110, shortening the positioning time, and further improving production efficiency.

[0081] In some embodiments, the transfer component 130 specifically includes a transfer vehicle and a lifting mechanism (not shown in the figure) disposed on the transfer vehicle. The lifting mechanism is used to drive the flat tooling 120 to move relative to the transfer vehicle along the height direction of the processing platform 100.

[0082] Here, the transfer vehicle can be an AGV (Automated Guided Vehicle) as well known to those skilled in the art, and the lifting mechanism can include structures such as cylinders, hydraulic cylinders, and electric cylinders, without limitation.

[0083] In this embodiment, the transfer vehicle is equipped with a lifting mechanism. In actual use, the lifting mechanism can lift the flat tool 120 so that the bottom surface of the flat tool 120 is higher than the base 110, so that the transfer vehicle can transport the flat tool 120 to the top side of the base 110. Then, the lifting mechanism can lower the flat tool 120 so that the flat tool 120 is placed on the carrier 140. This arrangement helps to reduce costs.

[0084] In the embodiment where the pushing device 150 includes a first pushing member 151 and a second pushing member 152, the carrier member 140 can be fixed to a fixed surface of the base 110, and the carrier member 140 includes a bullseye bearing and / or a caster wheel. In this way, the flat tooling 120 can achieve a sliding fit with the base 110 in both the first and second directions at a lower cost.
