Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a lifting device for a machine tool. Background Art

[0002] A machine tool refers to a machine for manufacturing machines, also known as a mother machine or machine tool, and is usually referred to as a machine tool. It is generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, all parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools using cutting methods. When the machine tool is processing an object, it is first necessary to clamp the object to be processed, and then process the object to be processed. However, since the position of the clamping device and the cutting device of the machine tool are fixed, and the sizes of different processing objects are also different, when the processing object needs to be processed at different heights and angles, the height and angle of the clamping device need to be adjusted.

[0003] According to the Chinese patent application number 202223085087.6, a machine tool lifting device is disclosed, including a table top, a through groove is opened at the upper end of the table top, a bearing plate is arranged in the through groove, a support plate is arranged under the bottom of the table top, and hydraulic cylinders are fixedly installed on both sides of the upper end of the support plate and at corresponding positions of the bearing plate. By opening a through groove on the table top, and setting the bearing plate in the through groove, the support plate is installed at the bottom of the table top using a support frame, and the hydraulic cylinder is installed on the support plate.

[0004] By adopting the above scheme, the height adjustment of the supporting plate is controlled by a hydraulic cylinder so that it can be raised and lowered in the through groove. At the same time, a guide rail is installed on the supporting plate, and a loading plate with a mechanical clamp is installed on the guide rail, so that the mechanical clamp is used to clamp the workpiece, and the lifting of the mechanical clamp is controlled by the hydraulic cylinder, thereby solving the problem that the position height of the workpiece cannot be adjusted when clamping the workpiece, and the problem that the processing cannot be accurately positioned. However, in the actual use of the above scheme, when it is necessary to drill holes at an oblique angle on the workpiece, the angle of the workpiece cannot be adjusted, which has certain shortcomings. For this reason, we provide a machine tool lifting device to solve the above problems. Utility Model Content

[0022] The present embodiment provides a machine tool lifting device, which is used to drive the workpiece to be lifted and lowered when the machine tool is processing the workpiece. By using the cooperation between the set driving mechanism 5, the angle adjustment mechanism 6 and the mechanical clamp 7, the angle of the workpiece can be adjusted when the machine tool is processing the workpiece, thereby facilitating the oblique angle drilling of the workpiece, thereby improving the practicality of the device.

[0024] By using the two mechanical grippers 7, the workpiece can be clamped on the machine tool. The mechanical grippers 7 are a mature technology well known to people in the technical field.

[0025] The lifting mechanism 3 includes a support plate 301 , the outer surfaces of which are fixedly connected to the outer surfaces of the four base columns 2 , respectively, and the upper surface of the support plate 301 is fixedly connected to two symmetrical electric push rods 302 .

[0026] The output ends of the two electric push rods 302 are fixedly connected with a collecting tank 303 , and the outer surface of the collecting tank 303 is slidably connected with the inner wall of the supporting bottom tank 1 .

[0027] The two electric push rods 302 are synchronously driven by the same switch. By starting the electric push rods 302, the collecting trough 303, the supporting trough 501 and the two mechanical grippers 7 can be driven to move up and down, and the workpiece can be driven to move up and down, so that holes can be punched at different heights on the workpiece. The side of the collecting trough 303 should be provided with a slot for removing debris.

[0028] The bottom surface of the limiting groove 505 is fixedly connected with two symmetrical positioning grooves 504 , the inner walls of the two positioning grooves 504 are slidably connected with the limiting slide rails 503 , and the bottom surfaces of the two limiting slide rails 503 are fixedly connected with the supporting grooves 501 .

[0029] By using the provided limiting slide rail 503, the sliding of the positioning groove 504 can be limited, so as to avoid the positioning groove 504, the limiting groove 505 and the workpiece from sliding and deviating when the machine tool processes the workpiece.

[0030] The bottom surface of the support groove 501 is fixedly connected to the upper surface of the collecting groove 303 , the outer surface of the support groove 501 is slidably connected to the inner wall of the supporting bottom groove 1 , and a filter plate 502 is installed inside the support groove 501 .

[0031] By using the provided filter plate 502 , it is possible to prevent the workpiece from directly falling into the interior of the collection tank 303 , and to allow the debris generated by punching the workpiece to fall into the interior of the collection tank 303 .

[0032] The outer surface of the rotating disk 604 is rotatably connected to the inner wall of the limiting groove 505 . A group of circumferentially arranged plug holes 605 are provided inside the rotating disk 604 . A group of circumferentially arranged indicating openings 606 are provided on the upper surface of the rotating disk 604 .

[0035] The set spring 603 is in a relaxed state in a natural state. By using the set spring 603, the pull rod 602 can continuously limit one of the sockets 605, so that the workpiece processed on the machine tool can be positioned at different angles.

[0036] Working principle: When the workpiece needs to be processed by the machine tool, the workpiece is first clamped with two mechanical grippers 7, and then the electric push rod 302 is started by the external switch, which can drive the collection slot 303, the support slot 501 and the two mechanical grippers 7 to move up and down, so as to drive the workpiece to rise and fall. By starting the puncher 8 and pushing the limit slot 505 and the positioning slot 504 to slide on the outer surface of the limit slide rail 503, so that the workpiece is close to the puncher 8, the workpiece can be punched, so that holes can be punched at different heights on the workpiece. By pulling the pull plate 601 forward, the pull rod 602 can be driven to release the limit on the rotating disk 604, so that the rotating disk 604 can be rotated, thereby driving the two mechanical grippers 7 and the workpiece to rotate, so that the workpiece can be rotated to a suitable angle, and then the workpiece can be punched at an oblique angle.
