Description
Technical Field
[0001] The utility model relates to the technical field of roll grinding machines, and more specifically, the utility model relates to an automatic adjusting device for a numerical control roll grinding machine. Background Technique
[0002] A roll grinding machine is a metal cutting machine tool, which consists of a bed, a headstock, a tailstock, a bracket, a longitudinal and transverse carriage, a grinding head, a measuring stand and an electrical numerical control system, and is divided into five subsystems: a bearing system, a driving system, a grinding system, a measuring system and a control system. The workpiece is supported by the headstock, the tailstock and the bracket, and is driven to rotate by the headstock. The numerical control system controls the machine tool to perform multi-axis compound motion according to the mathematical model of the surface generatrix of the roll, and realizes the grinding of the roll surface metal by the grinding wheel during the motion. The on-line measuring system real-time feeds back the measurement data to the grinding machine control system, and the control system performs closed-loop control on the machine tool, so as to complete the precision machining of the workpiece.
[0003] Among them, the patent with the publication number CN215394198U discloses a grinding machine platform, on the upper end of which a connection housing is fixedly installed. An electric motor is fixedly installed on the outer end of the connection housing. The connection end of the electric motor penetrates through the side wall of the connection housing. A driving gear is fixedly installed on the connection end of the electric motor. The driving gear is rotatably connected with the connection housing. A first roll assembly is fixedly installed on one side of the driving gear. One end of the first roll assembly penetrates through the side wall of the connection housing. The outer circumferential surface of the driving gear meshes with a driven gear. The driven gear is rotatably connected with the connection housing. A second roll assembly is fixedly installed on one side of the driven gear;
[0004] When this structure is in use, the driving gear and the driven gear are driven by the electric motor to mesh with each other, so as to adjust the distance between the first roll assembly and the second roll assembly. However, the distance between each tooth is fixed, resulting in that this structure can only be adjusted with a single stroke distance after the driving gear and the driven gear mesh, and cannot meet different adjustment requirements.

The second spring itself elastically drives the supporting inclined block to approach the polishing disc, so that the workpiece can be clamped between the pad roller and the polishing disc, ensuring the stability of the workpiece during processing.
[0014] And through the elasticity of the first spring itself, the function of adjusting the position of the cushion roller is realized, so that the workpiece, the polishing disc and the cushion roller can be fitted together only by placing the workpiece, realizing the function of automatic adjustment and making the device more convenient to use.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] As shown in the atta Figures 1-5An automatic adjustment device for a numerically controlled roll grinder as shown. Through the adjustment component arranged on the support vertical plate 1, the polishing disc 5 is driven to rotate by the second rotating shaft 4 to polish the workpiece through the polishing disc 5. The workpiece is supported by the cushion roller 8. The elastic force of the second spring 13 drives the support inclined block 6 to approach the polishing disc 5, so that the workpiece can be clamped between the cushion roller 8 and the polishing disc 5, ensuring the stability of the workpiece during processing. And the elastic force of the first spring 11 realizes the function of adjusting the position of the cushion roller 8, realizing that only by placing the workpiece can the workpiece, the polishing disc 5 and the cushion roller 8 be fitted together, realizing the function of automatic adjustment. And the specific structure of the component is as follows;
[0024] The adjustment component includes a first rotating shaft 2 arranged on one side of the support vertical plate 1. A traction disc 3 is clamped on the outer side of the first rotating shaft 2. A second rotating shaft 4 is arranged on the top of the first rotating shaft 2. A polishing disc 5 is sleeved on the second rotating shaft 4;
[0025] Support inclined blocks 6 are arranged on both sides of the traction disc 3. Installation grooves 7 are formed on both support inclined blocks 6. A cushion roller 8 is arranged in the installation groove 7. A spiral polishing strip 9 is arranged on the cushion roller 8. A horizontal shaft 10 is arranged in the middle of the cushion roller 8. The horizontal shaft 10 extends to the support inclined block 6. A first spring 11 is arranged at one end of the cushion roller 8. The first spring 11 is sleeved on the outer side of the horizontal shaft 10. The two support inclined blocks 6 are both arranged obliquely upward, and the vertical cross-sectional shapes of the two support inclined blocks 6 are combined into an eight-shaped;
[0026] Two sliding grooves 12 are penetrated through the surface of the support vertical plate 1, and each sliding groove 12 is respectively located on one side of the bottom of the corresponding support inclined block 6. Second springs 13 are installed in the two sliding grooves 12, and one end of each second spring 13 is provided with a slider 14. The slider 14 is matched with the sliding groove 12.

When processing the workpiece, the workpiece is placed between the polishing disc 5 and the traction disc 3. The polishing disc 5 is driven to rotate by the second rotating shaft 4 to polish the workpiece through the polishing disc 5. At the same time, the workpiece can be supported by the cushion roller 8. When the workpiece is placed on the cushion roller 8, the cushion roller 8 and the support inclined block 6 are stressed, so that the support inclined block 6 adjusts its position on the support vertical plate 1 along the guide of the sliding groove 12 through the slider 14, and the second spring 13 is compressed. The elastic force of the second spring 13 drives the support inclined block 6 to approach the polishing disc 5, so that the workpiece can be clamped between the cushion roller 8 and the polishing disc 5;
[0028] Meanwhile, through the arrangement of the spiral strip 9, the friction between the workpiece and the backing roll 8 is increased, thereby ensuring the stability of the workpiece between the polishing disc 5 and the backing roll 8. At the same time, the function of adjusting the position of the backing roll 8 is realized through the elasticity of the first spring 11 itself, so that the workpiece, the polishing disc 5 and the backing roll 8 can be made to fit together only by placing the workpiece, realizing the function of automatic adjustment.
[0029] Moreover, the traction disc 3 is clamped with the first rotating shaft 2, which is convenient for the staff to replace the traction disc 3 of the corresponding size according to the size of the workpiece itself, and it is easy for the device to indicate workpieces of different sizes during use.
[0030] Different from the prior art, the present application discloses an automatic adjustment device for a numerical control roll grinder. The polishing disc 5 is driven to rotate by the second rotating shaft 4 to polish the workpiece through the polishing disc 5, and it is supported by the backing roll 8. The elastic force of the second spring 13 drives the supporting inclined block 6 to approach the polishing disc 5, so that the workpiece can be clamped between the backing roll 8 and the polishing disc 5, ensuring the stability of the workpiece during processing. At the same time, the function of adjusting the position of the backing roll 8 is realized through the elasticity of the first spring 11 itself, so that the workpiece, the polishing disc 5 and the backing roll 8 can be made to fit together only by placing the workpiece, realizing the function of automatic adjustment.
[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
