[0021] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1-Figure 3 The utility model proposes a crossbeam structure for fixing the main shaft, including a support frame 1, a support mechanism 2, a slide groove 3, a screw connection seat 4, and a mounting mechanism 5. The mounting mechanism 5 is symmetrically distributed on the side of the support frame 1. The support mechanism 2 is installed on the inner side of the support frame 1, and the mounting mechanism 5 is installed on the other side of the support frame 1. The material of the support frame 1 can be high-strength steel or aluminum alloy. High-strength steel has high load-bearing capacity and durability, and aluminum alloy has the characteristics of light weight and corrosion resistance. High-strength steel is suitable for heavy-load environments and provides excellent deformation resistance, while the lightweight characteristics of aluminum alloy help to reduce the overall weight and improve operational flexibility.

[0023] The support mechanism 2 includes a transverse plate 201, a longitudinal plate 202, and a raised plate 203. The transverse plate 201 and the longitudinal plate 202 are arranged at equal distances on the inner wall of the support frame 1, and the transverse plate 201 is fixedly installed on the inner side of the support frame 1. The transverse plate 201 can be fixed by welding or bolting. Welding can provide higher strength and stability, while bolting is convenient for disassembly and maintenance. The welding method ensures the firmness of the connection and the continuity of the overall structure, while the bolting method provides flexibility and maintainability. The top surface of the transverse plate 201 is fixedly installed with the longitudinal plate 202, which is fixed by riveting or bolting. The riveting method can ensure a tight combination and avoid loosening. Riveting provides a permanent connection to ensure that it will not loosen during long-term use, while the bolting is convenient for replacement and adjustment. The bottom surface of the transverse plate 201 is fixedly installed with a raised plate 203, which can be welded or threaded, so that the lateral bearing capacity of the transverse plate 201 can be effectively enhanced and the overall strength of the support frame 1 can be improved. The raised plate 203 increases the bending strength of the cross plate 201 by increasing the contact area and structural support, and further reduces the risk of deformation. The bottom surface of the support frame 1 is provided with a slide groove 3, which can be used in conjunction with a slide rail. The slide rail can be a guide rail or a rolling bearing guide rail to ensure that the support frame 1 can slide smoothly, thereby improving the processing accuracy. The guide rail can be a high-precision linear guide rail to provide smooth linear motion, while the rolling bearing guide rail can reduce friction and improve the motion efficiency. A screw rod connection seat 4 is fixedly installed on one side of the support frame 1. The inner wall of the screw rod connection seat 4 is provided with a thread. The screw rod connection seat 4 can be connected to the support frame 1 by welding or bolting. The thread can ensure the stable connection of the screw rod, thereby driving the support frame 1 to run. The design of the screw rod connection seat 4 enables the screw rod to accurately transmit power, drive the support frame 1 to move along the slide rail, and ensure accurate positioning and stable movement. The side of the support frame 1 is provided with a weight reduction groove 6, which is evenly distributed on the side of the support frame 1. The weight reduction groove 6 can be processed by cutting or milling technology to reduce weight while maintaining structural strength. The design of the weight-reducing grooves 6 can effectively reduce the deadweight of the structure and reduce energy consumption without affecting the overall strength and stability of the support frame 1. By optimizing the shape and distribution of the weight-reducing grooves 6, the weight efficiency of the structure can be further improved.

[0024] The mounting mechanism 5 includes a base plate 501, a bottom sleeve 502, a top sleeve 503, a connecting sleeve 504, and a mounting groove 505. The base plate 501 is fixedly mounted on the side of the support frame 1, and can be fixed by bolts or welding to ensure stability. The bolt fixing method is convenient for disassembly and maintenance, while the welding method provides higher rigidity and stability. The surface of the base plate 501 is provided with a mounting groove 505, and the inner wall of the mounting groove 505 is fixedly mounted with a bottom sleeve 502, and the bottom sleeve 502 can be fixed by a thread or a buckle method, which is convenient for installation and disassembly. The threaded connection method provides high strength and reliability, while the buckle method provides the convenience of quick installation and disassembly. The top sleeve 503 is fixedly mounted on the top of the inner wall of the mounting groove 505, and the bottom surface of the top sleeve 503 is fixedly mounted with a connecting sleeve 504, and the connecting sleeve 504 is fixed by a threaded connection or welding method. The threaded connection is convenient for replacement and maintenance, and the welding method provides higher structural stability.

[0025] The surfaces of the bottom sleeve 502, the top sleeve 503 and the connecting sleeve 504 are all provided with mounting holes 506, which can be used to fix the spindle, and the spindle is installed by bolts or buckles to ensure stable and reliable installation. The mounting mechanism 5 designed in this way can effectively fix the spindle of the machine tool, ensure that the spindle remains stable during the processing, thereby improving the processing accuracy and product quality. The precision processing of the mounting holes 506 ensures the stable installation of the spindle and reduces vibration and displacement under high load conditions.

[0026] In this embodiment, the mounting groove 505 opened in the bottom sleeve 502, the top sleeve 503 and the connecting sleeve 504 can be used to fix the spindle of the machine tool, and the set slide groove 3 can be installed on the slide rail to allow the support frame 1 to slide smoothly. The screw connecting seat 4 is connected to the screw, and the screw can drive the support frame 1 to operate through the screw connecting seat 4. In the support frame 1, the horizontal plate 201 and the vertical plate 202 can provide horizontal and vertical support, thereby improving the structural strength of the support frame 1, and the raised plate 203 can be used to strengthen the horizontal plate 201, thereby improving the lateral bearing capacity of the horizontal plate 201, thereby reducing the deformation probability of the support frame 1 and improving the service life. The utility model provides horizontal and vertical dual support by arranging the horizontal plate 201 and the vertical plate 202 in the support frame 1. This design can significantly enhance the overall structural strength of the support frame 1, making it more stable and durable when subjected to external forces, and the raised plate 203 is provided to strengthen the horizontal plate 201, effectively improving the lateral load-bearing capacity of the horizontal plate 201, which not only enables the horizontal plate 201 to withstand greater lateral pressure, reducing its risk of deformation under heavy loads, but also ensures that the spindle remains stable during processing. In summary, the above design reduces the probability of deformation of the support frame 1 during use by enhancing the support and load-bearing capacity in all directions. This improvement enables the support frame 1 to maintain its structural integrity during long-term use and avoids reduced accuracy or failures caused by deformation.

[0027] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
