Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to an edge grinding device for machining mechanical parts. Background Technology

[0002] In the field of mechanical manufacturing and parts processing, edge grinding is a key process to ensure the accuracy, surface quality and safety of workpieces.

[0003] A search revealed that Chinese Patent CN222095571U discloses a grinding device for edge grinding. This device places a sheet material on a grid frame plate, allowing the edges of the material to adhere to the surface of a grinding wheel. The grinding wheel is then activated to grind the edges of the material. However, in actual production, the common edge grinding method uses the outer circumference of the grinding wheel, which offers high linear speed and efficiency. Flat surface grinding typically uses the end face (side) of the grinding wheel, resulting in a large contact area. However, this device cannot adjust the grinding wheel and focuses solely on edge grinding, making it unsuitable for flat surface grinding and limiting its applicability. Therefore, an edge grinding device for machining mechanical parts is proposed to address these issues. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-7 This utility model provides an edge grinding device for machining mechanical parts. It is used for grinding the edges of mechanical parts during machining. By using a grinding wheel with a fixed direction, it can simultaneously complete both surface grinding and edge grinding of mechanical parts, thus improving its applicability. Technical solution:

[0027] An edge grinding device for machining mechanical parts includes: a base 1, the upper surface of which is formed with a support area 11 for supporting the parts and a downwardly recessed edge grinding area 12; a gantry 2, movably mounted on the base 1 and capable of moving along the length of the base 1 between the support area 11 and the edge grinding area 12; a grinding motor 3, mounted on one side of the gantry 2, the output end of the grinding motor 3 being fixedly connected to a grinding wheel 4, the axis of the grinding wheel 4 being perpendicular to the upper surface of the base 1; when the grinding wheel 4 corresponds to the support area 11, its lower end faces the upper surface of the parts for planar grinding; when it corresponds to the edge grinding area 12, its circumferential outer surface faces the edge of the parts for edge grinding.

[0028] Specifically, by setting a support area 11 and a recessed edge grinding area 12 on the same base 1, and cooperating with a movable gantry 2, the grinding of mechanical parts can be completed simultaneously using only a grinding wheel 4 with a fixed direction. This significantly expands the applicability of the equipment. At the same time, there is no need to design complex angle adjustment, flipping or locking mechanisms for the grinding wheel 4. The grinding mode and grinding position can be switched simply by the linear movement of the gantry 2, which solves the problem of limited applicability of the existing equipment. On the other hand, after the workpiece is clamped in the support area 11 once, the grinding of the plane and the edge can be completed sequentially by moving the gantry 2. This avoids the cumbersome process of multiple clamping, equipment change or tool change, reduces auxiliary time and improves production efficiency.

[0029] A movable beam 21 is slidably connected to the inner wall of the gantry frame 2. A connecting seat 22 is provided on the surface of the movable beam 21. A frame 23 is fixedly connected to one side of the connecting seat 22. The grinding motor 3 is fixedly connected to the inner wall of the frame 23. A cylinder 24 is fixedly connected to the top of the gantry frame 2. The output end of the cylinder 24 is fixedly connected to the top of the movable beam 21. The output end of the cylinder 24 drives the movable beam 21 to move downward. The movable beam 21 drives the connecting seat 22 to move. The connecting seat 22 drives the frame 23. The frame 23 drives the grinding motor 3 and the grinding wheel 4 to move, which facilitates the adjustment of the height of the grinding wheel 4.

[0030] A longitudinal guide rail 25 is fixedly connected to the side of the movable beam 21 away from the frame 23. A longitudinal sliding seat 26 is slidably connected to the surface of the longitudinal guide rail 25. A connecting seat 22 is fixedly connected to the bottom of the longitudinal sliding seat 26. The connecting seat 22 is slidably connected to the movable beam 21 through the longitudinal sliding seat 26. A drive motor 27 is fixedly connected to the bottom of the longitudinal sliding seat 26. The output end of the drive motor 27 passes through the top of the longitudinal sliding seat 26 and is fixedly connected to a gear 28. A rack 29 is fixedly connected to some parts of the movable beam 21. The gear 28 meshes with the rack 29. The output end of the drive motor 27 drives the gear 28 to rotate. With the cooperation of the rack 29, the gear 28 is displaced in the length direction of the rack 29, so that the connecting seat 22 drives the frame 23, the grinding motor 3, and the grinding wheel 4 to reciprocate along the length direction of the movable beam 21 to complete the grinding work.

[0031] A protective cover 5 is fixedly connected to the side of the movable beam 21 near the longitudinal guide rail. A bellows cover 6 is fixedly connected to both the front and rear sides of the longitudinal sliding seat 26. The other end of the bellows cover 6 is fixedly connected to the inner wall of the protective cover 5. The protective cover 5 and the bellows cover 6 cooperate to prevent impurities generated during the grinding process from causing accelerated wear to the longitudinal guide rail 25, the longitudinal sliding seat 26, the gear 28, and the rack 29.

[0032] The base 1 has a seat body 13 at its bottom. The front and rear sides of the seat body 13 are fixedly connected to transverse guide rails 14. The surface of the transverse guide rails 14 is slidably connected to transverse sliders 15. The two ends of the gantry frame 2 are fixedly connected to the two sides of the transverse sliders 15 that are far apart from each other. The transverse guide rails 14 and transverse sliders 15 cooperate to ensure that the gantry frame 2 can move stably.

[0033] A cavity 16 is provided through the front side of the base 13. A connecting rod 17 is provided inside the cavity 16. The top of the connecting rod 17 is fixedly connected to the bottom of two horizontal sliders 15. A threaded screw 18 is rotatably connected to the inner wall of the cavity 16. The connecting rod 17 is threadedly connected to the threaded screw 18. A power motor 19 is fixedly connected to one side of the base 13. The output end of the power motor 19 is fixedly connected to one end of the threaded screw 18. The output end of the power motor 19 drives the threaded screw 18 to rotate. The threaded screw 18 drives the connecting rod 17 to move along the cavity 16. The connecting rod 17 drives the horizontal sliders 15 to move. The horizontal sliders 15 drive the gantry frame 2 to move along the length direction of the base 1.

[0034] The width of the base 13 is smaller than the width of the support area 11 and the edge grinding area 12. The projection of the horizontal slider 15 in the vertical direction is completely within the projection range of the support area 11 and the edge grinding area 12. This is to prevent impurities generated during the grinding process from causing accelerated wear to the horizontal guide rail 14, the horizontal slider 15 and the threaded screw 18.

[0035] Working principle: When using this edge grinding device for machining mechanical parts, the user first clamps the part onto the support surface, so that the edge of the part to be ground is suspended above the edge grinding area 12. Then, the power motor 19 is started. The output end of the power motor 19 drives the threaded screw 18 to rotate. The threaded screw 18 drives the connecting rod 17 to move along the cavity 16. The connecting rod 17 drives the transverse slider 15 to move. The transverse slider 15 drives the gantry 2 to move along the length of the base 1, so that the grinding wheel 4 moves to the position corresponding to the edge grinding area 12. Then, the cylinder 24 is started. The output end of the cylinder 24 drives the movable beam 21 to move downward. The movable beam 21 drives the connecting seat 22 to move. The connecting seat 22 drives the frame 23. The frame 23 drives the grinding motor 3 and the grinding wheel 4 to move, so that the grinding wheel 4 moves along the edge grinding area 12. The grinding wheel 4 contacts the edge to be ground, and then the grinding motor 3 is started. The output end of the grinding motor 3 drives the grinding wheel 4 to rotate for edge grinding. At the same time, the drive motor 27 is started, and the output end of the drive motor 27 drives the gear 28 to rotate. With the cooperation of the rack 29, the gear 28 is displaced in the length direction of the rack 29, so that the connecting seat 22 drives the frame 23, the grinding motor 3, and the grinding wheel 4 to reciprocate along the length direction of the movable beam 21 to complete the grinding work. When it is necessary to grind the upper surface of the parts, the grinding wheel 4 is also moved to the support area 11, and the lower end of the grinding wheel 4 is used to grind the upper surface of the parts. This grinding device can complete both the surface grinding and edge grinding of mechanical parts at the same time by using only a grinding wheel 4 with a fixed direction, thus expanding the applicability of the equipment.
