Description

Technical Field

[0001] The utility model relates to the technical field of parts grinding, in particular to a device for grinding the surface of curved parts. Background Art

[0002] A grinder is a mechanical device that processes the surface of a workpiece through a rotating grinding wheel or brush. Its main principle is to use the high-speed rotation of the grinding wheel or brush to grind the workpiece being processed and to flatten or polish the irregular parts on its surface.

[0003] However, in the prior art, most of the existing grinding machines are manually handheld to grind the surface of parts, and the parts need to be fixed during processing to ensure their stability. However, when fixedly grinding curved parts such as cylindrical parts, since the grinding surface is curved, it is necessary to move the grinder back and forth in an arc during grinding, which has high technical requirements for the operating workers, is difficult to process, is time-consuming and labor-intensive, and has low work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: when fixed processing and grinding of curved parts such as cylindrical parts, since the grinding surface is curved, it is necessary to move the grinder back and forth in an arc during grinding, which has high technical requirements for the operating workers, is difficult to process, is time-consuming and labor-intensive, and has low work efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a curved part surface grinding device comprises a work counter, a No. 1 electric telescopic rod is fixed inside the work counter, and a mounting plate is fixed at one end of the No. 1 electric telescopic rod, a No. 1 motor is fixed on the upper surface of the mounting plate, a main shaft is fixed on the output end of the No. 1 motor, and the main shaft is slidably connected with the work counter, a grinding roller is fixed on one end of the main shaft, a vertical plate is fixed on the upper surface of the work counter, and a movable plate is slidably connected on the vertical plate, a No. 2 electric telescopic rod is fixed on one side of the vertical plate, and the No. 2 electric telescopic rod is fixed to the movable plate, a No. 2 motor is fixed on the top of the movable plate, and the output shaft of the No. 2 motor passes through the movable plate and is fixed with a connecting piece, small motors are fixed on both sides of the connecting piece, and a screw is fixed on the output end of the small motor, the screw and the connecting piece are rotatably connected, an extrusion plate is threadedly connected to the screw, and the extrusion plate is slidably connected to the connecting piece.

[0006] As a preferred implementation, a protective plate is fixedly connected to the edge of the movable plate, and the protective plate is made of a transparent material.

[0007] As a preferred implementation, a rubber pad is fixedly connected to the extrusion surface of the extrusion plate.

[0008] As a preferred embodiment, an area mark is provided on the surface of the work counter directly below the extrusion plate.

[0009] As a preferred implementation, the length of the extrusion surface of the extrusion plate extends to the bottom of the protective plate and is consistent with the suspended height of the bottom of the protective plate and the length of the grinding roller.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model allows the extrusion plate to pass through the center of the cylindrical part with the help of the No. 2 electric telescopic rod, and the extrusion plate is moved to clamp and fix the cylindrical part through the rotation of the screw rod. Under the action of the No. 2 motor, the connecting piece is rotated, thereby driving the clamped cylindrical part to rotate together. The No. 1 electric telescopic rod is contracted to make the rotating grinding roller contact with the surface of the rotating cylindrical part. The cylindrical part can be polished without the need for the grinding roller to move in an arc around the cylindrical part. The grinding operation is replaced by machinery instead of manual labor, which reduces the technical requirements of workers, reduces the difficulty of processing, saves time and effort, and improves work efficiency.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a curved part surface grinding device, including a work counter 1, an electric telescopic rod 2 is fixed inside the work counter 1, and a mounting plate 3 is fixed at one end of the electric telescopic rod 2, the mounting plate 3 is driven to move by the extension and contraction of the electric telescopic rod 2, and the left and right movement of the electric motor 4 and the grinding roller 6 is conveniently controlled, and the grinding roller 6 is adjusted and moved so as to make the grinding roller 6 in close contact with the grinding surface of the cylindrical part to ensure the grinding quality, a motor 4 is fixed on the upper surface of the mounting plate 3, a main shaft 5 is fixed at the output end of the motor 4, and the main shaft 5 is slidably connected with the work counter 1, and a grinding roller 6 is fixed at one end of the main shaft 5, with the help of the motor 4, it is convenient to make the grinding roller 6 rotate quickly to perform the grinding operation, a vertical plate 7 is fixed on the upper surface of the work counter 1, and a moving plate 8 is slidably connected to the vertical plate 7, a second electric telescopic rod 9 is fixed on one side of the vertical plate 7, and the second electric telescopic rod 9 is fixed to the moving plate 8, through With the help of the No. 2 electric telescopic rod 9, the lifting and lowering of the movable plate 8 is controlled, so that the extrusion plate 15 is conveniently immersed in the interior of the cylindrical part placed below for subsequent fixing operations. A No. 2 motor 11 is fixed on the top of the movable plate 8, and the output shaft of the No. 2 motor 11 passes through the movable plate 8 and is fixed with a connecting piece 12. Small motors 13 are fixed on both sides of the connecting piece 12, and a screw rod 14 is fixed to the output end of the small motor 13. The screw rod 14 is rotatably connected with the connecting piece 12. An extrusion plate 15 is threadedly connected to the screw rod 14, and the extrusion plate 15 is slidably connected with the connecting piece 12. With the help of the small motor 13, the screw rod 14 is driven to rotate and then the extrusion plate 15 is controlled to move, so that the extrusion plate 15 immersed in the cylindrical part clamps and fixes the cylindrical part, and the connecting piece 12 is rotated under the action of the No. 2 motor 11, thereby driving the clamped and fixed cylindrical part to rotate together, so that the grinding roller 6 can complete the grinding of the cylindrical part without arc movement, thereby reducing the technical requirements and difficulty of processing.

[0021] Example 2

[0022] like Figure 1-4As shown, a protective plate 10 is fixedly connected to the edge of the movable plate 8, and the protective plate 10 is made of a transparent material. When the movable plate 8 moves downward, the protective plate 10 covers the surrounding grinding area, so that the protective plate 10 plays a protective effect and effectively avoids accidental injury caused by flying debris during the grinding process. The transparent state of the protective plate 10 also facilitates the operator to observe the internal grinding situation in real time. A rubber pad 16 is fixedly connected to the extrusion surface of the extrusion plate 15. The rubber pad 16 effectively improves the friction of the extrusion surface of the extrusion plate 15, thereby enhancing the stability of the clamping of the cylindrical parts. The surface of the work counter 1 is provided with an area mark 17 directly below the extrusion plate 15, and the area mark 17 indicates the extrusion surface. The initial falling position of the pressing plate 15 allows the operator to understand the correct placement position of the cylindrical part on the work counter 1, so that the extrusion plate 15 can be smoothly immersed in the cylindrical part later. The length of the extrusion surface of the extrusion plate 15 extends to the bottom of the protective plate 10 and is consistent with the suspended height of the bottom of the protective plate 10 and the length of the grinding roller 6. By making the extrusion surface of the extrusion plate 15 consistent with the suspended height of the bottom of the protective plate 10, the protective plate 10 can be completely attached to the surface of the work counter 1 after the movable plate 8 is completely lowered, avoiding the generation of gaps that affect the protective effect of the protective plate 10. The consistency of the extrusion surface of the extrusion plate 15 and the length of the grinding roller 6 also facilitates the grinding roller 6 to completely grind the cylindrical part fixed on the extrusion plate 15.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model is in use, the user first places the hollow part of the cylindrical part upright near the area mark 17 of the work counter 1, and then controls the No. 2 electric telescopic rod 9 to contract to drive the movable plate 8 to move downward along the vertical plate 7 as a whole, and stops the contraction of the No. 2 electric telescopic rod 9 after the protective plate 10 is in contact with the work counter 1. At this time, the extrusion plate 15 is immersed in the cylindrical part, and then the small motor 13 controls the screw rod 14 to rotate, so that the extrusion plate 15 and the rubber pad 16 move, and then the rubber pad 16 contacts the cylindrical part to squeeze and fix the cylindrical part, and then the No. 2 motor 11 controls the connection piece 12 to rotate, thereby driving the extrusion plate 15 and the clamped cylindrical part to rotate, and then the No. 1 motor 4 controls the main shaft 5 and the grinding roller 6 to rotate, and the No. 1 electric telescopic rod 2 is contracted to drive the mounting plate 3 to move, so that the No. 1 motor 4 and the grinding roller 6 are moved, so that the grinding roller 6 is in close contact with the surface of the cylindrical part to grind it.
