Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a bed structure for a vertical and horizontal grinding machine. Background Technology

[0002] Vertical and horizontal grinding machines, as important metal processing equipment, are widely used in many fields such as machinery manufacturing, aerospace, and automotive industries. They can achieve high-precision grinding of various parts, playing a key role in improving the dimensional accuracy, surface quality, and overall performance of products. Existing vertical grinding machines have guide rails on the bed, which are directly exposed. During the grinding process, some debris falls onto the guide rails. When the slide on the guide rail moves, it pushes the debris along the rail, easily causing wear on the guide rail surface and thus affecting the stability of its accuracy. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bed structure for a vertical and horizontal grinding machine, which solves the technical problem of easy wear of the guide rails in existing bed structures.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bed structure for a vertical and horizontal grinding machine, including a bed body, a reinforcing component installed on the inner side of the bed body, two sets of guide rail assemblies installed on the bed body, a slide plate installed on both sets of guide rail assemblies, and a workpiece table assembly installed on the slide plate;

[0005] The guide rail assembly includes a guide rail mounted on the bed, a slide block slidably connected to the guide rail, and protective sleeves fitted on both sides of the slide block outside the guide rail. A fixing plate is fixed to one end of the protective sleeve on the side wall of the bed, and the other end of the protective sleeve is fixed to one end of the slide block.

[0006] Preferably, the reinforcement assembly includes a crossbeam installed on the inner side of the bed body, with multiple parallel longitudinal beams mounted on the crossbeam. Support blocks are provided at both ends of the crossbeam and the longitudinal beams, and the support blocks are fixed to the inner wall of the bed body by bolts.

[0007] Preferably, the support block has a positioning groove.

[0008] Preferably, each end of the guide rail is provided with a positioning block installed on the bed, and the positioning block is "U" shaped.

[0009] Preferably, the workpiece stage assembly includes a support base mounted on a slide plate, a mounting plate fixed on the support base, a servo motor fixed on the mounting plate, a pulley one fixed on the output shaft of the servo motor, the pulley one being connected to the pulley two via a multi-ribbed belt, the pulley two being fixed to the bottom of the workpiece stage, the workpiece stage being rotatably connected to a bearing seat, and the bearing seat being mounted on the inner side of the support base.

[0010] Preferably, the workpiece stage is provided with an electromagnetic platform.

[0011] By employing the above technical solution, this utility model provides a bed structure for a vertical and horizontal grinding machine, which has at least the following beneficial effects:

[0012] 1. The bed structure of this vertical and horizontal grinding machine, by setting a guide rail assembly and setting a protective sleeve on the guide rail, uses the protective sleeve to block the debris and prevent the debris from falling on the guide rail. Moreover, the protective sleeve can extend and retract with the movement of the slide, which can better protect the guide rail from wear and improve the running accuracy and service life of the guide rail on the bed.

[0013] 2. The bed structure of this vertical and horizontal grinding machine, through the setting of reinforcement components, can be reinforced from the inside by the action of the crossbeam and longitudinal beam, ensuring that the bed is not prone to deformation or damage during processing.

[0014] 3. The bed structure of this vertical and horizontal grinding machine, by setting up a workpiece table assembly, can drive the workpiece table to rotate using a servo motor, thereby enabling comprehensive grinding of the workpiece. At the same time, under the action of the electromagnetic table, the workpiece is simple and convenient to fix, which greatly improves the processing efficiency of the grinding machine.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Vertical and horizontal grinding machines typically refer to vertical and horizontal profile CNC grinding machines, which are multi-functional grinding machines that combine the features of vertical and horizontal grinding machines. They excel in the versatility of machining processes. They can perform not only traditional surface grinding, cylindrical grinding, and internal grinding, but also complex profile grinding.

[0026] Due to the inherent technical flaw of the existing technology, the guide rail 301 is prone to wear. Please refer to... Figures 1-6 This embodiment provides a bed structure for a vertical and horizontal grinding machine, which can protect the guide rails 301 from wear, improve the running accuracy and service life of the guide rails 301 on the bed 1. The bed structure includes a bed 1, a reinforcing component 2 installed on the inner side of the bed 1, two sets of guide rail components 3 installed on the bed 1, a slide 4 jointly installed on the two sets of guide rail components 3, and a workpiece table component 5 installed on the slide 4. Installing the reinforcing component 2 on the inner side of the bed 1 can significantly enhance the overall strength and rigidity of the bed 1, effectively resist various stresses and deformations generated during processing, thereby improving the stability and reliability of the equipment. The installation of two sets of guide rail components 3 can provide precise guidance and support for the slide 4, enabling the slide 4 to maintain high straightness and accuracy during operation, ensuring the accuracy of processing. The workpiece table component 5 can be used to install and fix the workpiece.

[0027] During the workpiece grinding process, some debris will fall onto the guide rail 301. When the slide 302 on the guide rail 301 moves, it will push the debris to slide on the guide rail 301, which can easily cause wear on the surface of the guide rail 301 and thus affect the stability of its accuracy. To address this issue, the guide rail assembly 3 includes a guide rail 301 mounted on the bed 1, a slide 302 slidably connected to the guide rail 301, and protective sleeves 303 on both sides of the slide 302 that are fitted over the outside of the guide rail 301. A fixing plate 304 is fixedly installed on the side wall of the bed 1 and is fixedly connected to one end of the protective sleeve 303. The other end of the protective sleeve 303 is fixedly connected to one end of the slide 302. The guide rail 301, as the core component of the guide rail assembly 3, is installed on the bed 1 to provide a precise sliding track for the slide 302. The protective sleeve 303 can effectively prevent the guide rail 301 from being invaded by external debris, dust, chips, etc., reduce the wear and damage of the guide rail 301, and extend the service life of the guide rail 301.

[0028] To address the issue of insufficient structural strength in existing bed frames, please refer to... Figure 2 The reinforcing component 2 includes a crossbeam 201 installed inside the bed 1. Multiple parallel longitudinal beams 202 are mounted on the crossbeam 201. Support blocks 203 are provided at both ends of the crossbeam 201 and the longitudinal beams 202, and the support blocks 203 are fixed to the inner wall of the bed 1 by bolts 204. Installing the crossbeam 201 inside the bed 1 effectively enhances the strength and rigidity of the bed 1 in the transverse direction, disperses the transverse stress generated during processing, and reduces deformation of the bed 1. The crisscrossing structure of the multiple parallel longitudinal beams 202 on the crossbeam 201 further improves the overall strength and stability of the bed 1. This forms a robust frame structure that can better withstand various loads during processing. The support blocks 203 at both ends of the crossbeams 201 and longitudinal beams 202 are fixed to the inner wall of the bed 1 by bolts 204. This connection method is not only easy to install, but also provides reliable fixed support, ensuring that the crossbeams 201 and longitudinal beams 202 will not shift or loosen during operation, thus ensuring the stability and effectiveness of the reinforcement component 2. At the same time, the support blocks 203 can also evenly transfer the force of the crossbeams 201 and longitudinal beams 202 to the inner wall of the bed 1, improving the load-bearing capacity of the bed 1.

[0029] Furthermore, the support block 203 is provided with a positioning groove 2031; when installing the crossbeam 201 and the longitudinal beam 202, the positioning groove 2031 can provide precise positioning for the crossbeam 201 and the longitudinal beam 202, ensuring their accurate installation position inside the bed body 1, thereby ensuring the installation accuracy of the reinforcement component 2 and the stability of the overall structure.

[0030] Furthermore, each end of the guide rail 301 is provided with a positioning block 305 mounted on the bed 1. The positioning block 305 is "U" shaped. The positioning block 305 can restrict the horizontal movement of the guide rail 301, ensuring the installation accuracy and stability of the guide rail 301.

[0031] When grinding a workpiece, it is necessary to rotate the workpiece relative to the grinding head. For this purpose, please refer to... Figure 6 The workpiece stage assembly 5 includes a support base 501 mounted on a slide plate 4. A mounting plate 502 is fixed to the support base 501, and a servo motor 503 is fixed to the mounting plate 502. A pulley 504 is fixed to the output shaft of the servo motor 503. The pulley 504 is connected to a second pulley 505 via a multi-ribbed belt. The second pulley 505 is fixed to the bottom of the workpiece stage 507. The workpiece stage 507 is rotatably connected to a bearing 506, which is mounted inside the support base 501. The servo motor 503, as a power source, features high precision, high response speed, and high torque output, enabling it to power the workpiece stage... The rotation of 507 provides stable and precise power, and the pulley 504 is connected to the pulley 505 via a multi-wedge belt, which can accurately transmit the power of the servo motor 503 to the bottom of the workpiece stage 507, realizing the rotation of the workpiece stage 507. The workpiece stage 507 can rotate flexibly to meet the needs of different processing angles. Furthermore, the workpiece stage 507 is equipped with an electromagnetic table. The electromagnetic table can quickly and firmly attract various ferromagnetic workpieces through the action of electromagnetic force, without the need for traditional clamps or bolts 204 for fixing, which greatly improves the workpiece clamping efficiency and reduces clamping time.
