Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to a grinding device for mechanical parts processing. Background Technology

[0002] Mechanical parts are an indispensable component of mechanical systems. Each part performs a specific function and together they ensure the normal operation of the equipment. They are the basic elements that constitute machinery and are inseparable individual components that make up machinery and machines.

[0003] In existing technologies, grinding is often required on the surface of parts, especially when processing tubular parts. Traditional grinding devices require the use of lead screw clamps to hold the tube to ensure processing stability. However, for tubular parts, the clamping end is often not ground properly during clamping, leading to repeated disassembly and assembly of the workpiece. This can also cause varying degrees of damage to the tube wall, resulting in low processing efficiency and unreliable processing quality. Therefore, there is an urgent need for a grinding device for machining mechanical parts. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for machining mechanical parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grinding device for machining mechanical parts includes a base, an electric grinding roller is mounted on the upper side of the base via a mounting bracket, the electric grinding roller is connected to an electric screw lifting mechanism to realize lifting operation, an assembly roller is provided below the electric grinding roller, a limit cylinder is provided in the middle of the assembly roller, and multiple rubber blocks are provided on the limit cylinder.

[0007] The assembly roller is driven to rotate by a drive motor. The assembly roller is internally limited by a connecting rod, which is provided with multiple conical extrusion blocks. Multiple mounting blocks are provided on the side away from each conical extrusion block. A rubber block is installed on one side of the mounting block. The mounting block is limited and fitted in the mounting groove opened on the outer wall of the limiting cylinder. When the conical extrusion block moves horizontally, the conical extrusion block extrudes the outer wall of the mounting block to achieve the displacement of the mounting block.

[0008] In addition, a preferred structure is that a drive motor is mounted on one side of the base via a mounting seat, the output end of the drive motor is connected to an assembly roller via a coupling, and a limiting cylinder is provided in the middle of the assembly roller.

[0009] In addition, a preferred structure is that one end of the connecting rod is provided with an extension rod, which extends outward and protrudes from the outer wall of the assembly roller. The outer wall of the assembly roller is provided with a groove to limit the extension rod. One side of the outer wall of the extension rod is pressed into contact with an adjusting ring, which is screwed to the threaded wall of the outer wall of the assembly roller.

[0010] Furthermore, in a preferred configuration, the outer wall of the limiting cylinder is provided with multiple mounting grooves at equal intervals, and a mounting block is mounted in the mounting groove. One end of the mounting block extends outward and is fitted with a pair of springs. The other end of the springs is connected to the inner wall of the limiting cylinder, and the springs deform when the mounting block moves through the mounting groove.

[0011] In addition, a preferred structure is that the inner wall of the limiting cylinder is equipped with multiple guide strips, the guide strips are connected to the mounting groove, and the middle of the guide strip is fitted with a mounting block.

[0012] Furthermore, in a preferred configuration, one end of the connecting rod is connected to the inner wall of the limiting cylinder via a spring.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, a rotating adjusting ring is used to push the connecting rod. During the movement of the connecting rod, it works with a conical extrusion block to push multiple mounting blocks inside the limiting cylinder, causing the rubber blocks to bulge outwards to press against the inner wall of the pipe fitting installed on the limiting cylinder. This ensures the installation stability of the pipe fitting. Furthermore, by fixing the pipe fitting by pressing against the inner wall, the processing dead angles of traditional clamps are avoided, and damage to the outer wall of the pipe fitting is prevented, thereby improving processing efficiency and ensuring processing quality.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-8 A grinding device for machining mechanical parts includes a base 1. An electric grinding roller 4 is mounted on one side of the upper part of the base 1 via a mounting bracket 2. The electric grinding roller 4 is connected to an electric screw lifting mechanism 3 to achieve lifting operation. An assembly roller 5 is provided below the electric grinding roller 4. A limit cylinder 51 is provided in the middle of the assembly roller 5. A plurality of rubber blocks 6 are provided on the limit cylinder 51.

[0026] Furthermore, the assembly roller 5 is driven to rotate by the drive motor 17. The assembly roller 5 is internally limited by a connecting rod 10. The connecting rod 10 is provided with multiple conical extrusion blocks 11. Multiple mounting blocks 15 are provided on the side away from each conical extrusion block 11. A rubber block 6 is installed on one side of the mounting block 15. The mounting block 15 is limited and fitted in the mounting groove 13 opened on the outer wall of the limiting cylinder 51. When the conical extrusion block 11 moves horizontally, the conical extrusion block 11 extrudes the outer wall of the mounting block 15 to achieve the displacement of the mounting block 15.

[0027] A drive motor 17 is mounted on one side of the base 1 via a mounting base 101. The output end of the drive motor 17 is connected to an assembly roller 5 via a coupling. A limit cylinder 51 is provided in the middle of the assembly roller 5.

[0028] One end of the connecting rod 10 is provided with an extension rod 8. The extension rod 8 extends outward and extends out of the outer wall of the assembly roller 5. The outer wall of the assembly roller 5 is provided with a groove 7 to limit the extension rod 8. One side of the outer wall of the extension rod 8 is pressed into contact with an adjusting ring 9. The adjusting ring 9 is screwed into the threaded wall 52 provided on the outer wall of the assembly roller 5.

[0029] The assembly roller 5 has slots at both ends that fit the connecting rod 10 to meet the assembly requirements of the connecting rod 10. When the connecting rod 10 moves horizontally, it simultaneously drives multiple conical extrusion blocks 11 to move.

[0030] The outer wall of the limiting cylinder 51 is provided with multiple mounting grooves 13 at equal intervals. The mounting block 15 is installed in the mounting groove 13. One end of the mounting block 15 extends outward and is equipped with a pair of springs 16. The other end of the springs 16 is connected to the inner wall of the limiting cylinder 51. When the mounting block 15 moves through the mounting groove 13, the springs 16 deform.

[0031] Multiple guide strips 14 are installed on the inner wall of the limiting cylinder 51. The guide strips 14 are connected to the mounting groove 13, and the mounting block 15 is installed in the middle of the guide strip 14.

[0032] One end of the connecting rod 10 is connected to the inner wall of the limiting cylinder 51 via a spring 12. When the connecting rod 10 moves, it is reset by the deformation of the spring 12.

[0033] The rotation direction of the threaded wall 52 is opposite to the rotation direction of the drive motor 17 to prevent the adjusting ring 9 from becoming loose;

[0034] The rotation direction of the drive motor 17 is opposite to that of the electric grinding roller 4, so as to satisfy the grinding operation on the outer wall of the pipe.

[0035] In this embodiment, the pipe to be processed is fitted onto the limiting cylinder 51, and its horizontal position is adjusted appropriately so that it is in the grinding area of ​​the electric grinding roller 4. Then, the adjusting ring 9 is rotated to move it horizontally. The adjusting ring 9 squeezes and pushes the extension rod 8 extending from one end of the connecting rod 10, and drives the connecting rod 10 to move horizontally. The connecting rod 10 moves simultaneously with multiple conical extrusion blocks 11. During the movement, the conical extrusion blocks 11 push against multiple mounting blocks 15 assembled inside the limiting cylinder 51, causing the mounting blocks 15 to move outward, causing multiple rubber blocks 6 connected to them to protrude outward (outer wall of the limiting cylinder 51), thereby squeezing and tightening the inner wall of the pipe, and achieving the tightening and fixing of the pipe.

[0036] Then, the drive motor 17 drives the assembly roller 5 to rotate. At the same time, the electric screw lifting mechanism 3 drives the electric grinding roller 4 to descend and contact the surface of the pipe. The electric grinding roller 4 rotates to grind the surface of the pipe.

[0037] Due to its conical structure, the conical extrusion block 11 pushes the mounting block 15 during its lateral horizontal movement to achieve the displacement operation of the mounting block 15. The mounting block 15 achieves smooth and limited movement through the installation groove 13 and the guide bar 14. When the mounting block 15 is displaced, the spring 16 deforms.

[0038] In its natural state, the rubber block 6 is naturally embedded in the mounting groove 13 opened on the outer wall of the limiting cylinder 51.

[0039] Among them, the electric lead screw lifting mechanism 3 is specifically a lifting mechanism composed of an electric lead screw. An electric lead screw is an electric drive device that converts the rotational motion of an electric motor into the linear reciprocating motion of a push rod. Those skilled in the art can directly purchase and use it from the market, and will not be explained in detail here. In this device, the lifting operation is achieved by connecting the electric grinding roller 4 to the lead screw pair.

[0040] The electric grinding roller 4 is specifically a grinding roller driven by a motor, which is easy to understand intuitively and will not be explained further.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
