A grinding device that can be clamped at both ends

Abstract

This utility model relates to the technical field of grinding devices, specifically a grinding device capable of double-end clamping. It includes a body, a main linear motor mounted on the inner wall of the body, a sliding outer shell mounted at the bottom of the main linear motor, an auxiliary linear motor mounted inside the body, a fixed base mounted on the upper end of the auxiliary linear motor, and a main AC motor mounted on one side of the fixed base. A main threaded rod is connected to one side of the main AC motor, and a clamping base is threadedly connected to the main threaded rod. An auxiliary AC motor is mounted on one side of the clamping base. The improved grinding device, by adding a clamping base and a clamping plate, allows the auxiliary AC motors on both sides to drive the auxiliary threaded rod to rotate when clamping metal parts, thereby causing the clamping plate to slide and clamp. Then, a servo motor drives a rotating rod to rotate, causing the pressing head to press downwards, thus clamping and fixing the metal parts on both sides and preventing the parts from shaking during grinding.

Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device that can be clamped at both ends. Background Technology

[0002] Grinding equipment is a mechanical device used to grind the surface of metal castings. It uses a high-speed rotating grinding wheel to cut the surface of the casting, remove excess material and improve surface quality, and rub and polish the surface of the casting to obtain a smoother and brighter surface.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] When grinding hardware parts, existing equipment mostly uses a single clamp to hold the middle or one side of the part. When grinding longer parts, the grinding head will apply a large cutting force and friction force to the workpiece. Because the part is only clamped on one side, these forces will cause the workpiece to vibrate, resulting in wavy or uneven surfaces on the ground surface. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device that can be clamped at both ends, so as to solve the problem mentioned in the background art that the device cannot be clamped and fixed at both ends.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding device that can be clamped at both ends, including a body, a main linear motor installed on the inner wall of the body, a sliding outer shell installed at the bottom of the main linear motor, an auxiliary linear motor installed inside the body, a fixed base installed at the upper end of the auxiliary linear motor, and a main AC motor installed on one side of the fixed base;

[0007] A main threaded rod is connected to one side of the main AC motor, and a clamping base is threadedly connected to the main threaded rod. An auxiliary AC motor is installed on one side of the clamping base, and an auxiliary threaded rod is connected to one side of the auxiliary AC motor. A clamping plate is threadedly connected to the auxiliary threaded rod.

[0008] More preferably, the sliding housing is configured as a sliding structure via a main linear motor.

[0009] More preferably, a hydraulic cylinder is installed at the bottom of the sliding housing, a hydraulic rod is connected to the bottom of the hydraulic cylinder, and a grinding head is connected to the bottom of the hydraulic rod. The grinding head forms a telescopic structure through the cooperation of the hydraulic cylinder and the hydraulic rod.

[0010] More preferably, the clamping base forms a sliding structure through the cooperation of the main AC motor and the main threaded rod.

[0011] More preferably, the clamping plates are symmetrically installed about the transverse centerline of the clamping base.

[0012] In a further preferred embodiment, a servo motor is mounted on the upper end of the clamping plate, a rotating rod is connected to the bottom of the servo motor, and a pressing head is threadedly connected to the rotating rod. The pressing head forms a lifting structure through the cooperation of the servo motor and the clamping plate.

[0013] More preferably, a dustproof cotton is installed on one side of the machine body, and a fan is provided on one side of the dustproof cotton, with the central axis of the dustproof cotton coinciding with the transverse central axis of the fan.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This grinding device adds a clamping base and a clamping plate. When clamping hardware parts, the auxiliary AC motors on both sides drive the auxiliary threaded rod to rotate, which in turn drives the clamping plate to slide and clamp. Then, the servo motor drives the rotating rod to rotate, which causes the pressing head to press down, thus clamping and fixing the hardware parts on both sides and preventing the parts from shaking during grinding.

An auxiliary AC motor 903 is installed on one side of the clamping base 902. An auxiliary threaded rod 904 is connected to one side of the auxiliary AC motor 903. A clamping plate 905 is threadedly connected to the auxiliary threaded rod 904.

[0025] In this embodiment, as Figure 1 As shown, the sliding housing 3 forms a sliding structure through the main linear motor 2.

[0026] In this embodiment, as Figure 1 As shown, a hydraulic cylinder 4 is installed at the bottom of the sliding housing 3, a hydraulic rod 5 is connected to the bottom of the hydraulic cylinder 4, and a grinding head 6 is connected to the bottom of the hydraulic rod 5. The grinding head 6 forms a telescopic structure through the cooperation of the hydraulic cylinder 4 and the hydraulic rod 5.

[0027] In this embodiment, as Figure 4 As shown, the clamping base 902 forms a sliding structure through the cooperation of the main AC motor 9 and the main threaded rod 901.

[0028] In this embodiment, as Figure 1 and Figure 4 As shown, the clamping plates 905 are symmetrically installed about the transverse center line of the clamping base 902.

[0029] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, a servo motor 906 is installed on the upper end of the clamping plate 905, and a rotating rod 907 is connected to the bottom of the servo motor 906. A pressing head 908 is threadedly connected to the rotating rod 907. The pressing head 908 forms a lifting structure through the cooperation of the servo motor 906 and the clamping plate 905.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the grinding device with double-end clamping operates as follows:

[0032] First, the main AC motor 9 drives the main threaded rod 901 to rotate, which in turn drives the clamping base 902 to slide. The position of the clamping base 902 is adjusted according to the length of the hardware part. Then, the hardware part is placed on the clamping base 902. While clamping the hardware part, the auxiliary AC motors 903 on both sides drive the auxiliary threaded rods 904 to rotate, which drives the clamping plate 905 to slide and clamp laterally. Then, the servo motor 906 drives the rotating rod 907 to rotate, which causes the pressing head 908 to press down, cooperating with the clamping plate 905 to clamp and fix the hardware part. Then, the hydraulic cylinder 4 drives the hydraulic rod 5 to extend and retract, which in turn drives the grinding head 6 to extend and retract, so that the grinding head 6 can grind the hardware part. During grinding, the auxiliary linear motor 7 drives the hardware part to slide, so that the grinding head 6 can grind multiple positions of the hardware part.
