Description

Technical Field

[0001] This utility model belongs to the technical field of clamping and positioning devices used in machining, and particularly relates to a multi-angle grinding fixture for flat parts. Background Technology

[0002] In the existing technology, when performing multi-angle grinding on flat parts, it is necessary to adjust the angle of the grinding machine platform to complete the grinding work on different angle planes. However, adjusting the angle of the grinding machine platform usually takes a lot of time, and due to long-term mechanical wear errors and human errors, the dimensional accuracy of the ground parts may not meet the design requirements. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-angle grinding fixture for flat parts, which can adapt to grinding processes at different angles without adjusting the platform angle of the grinding machine, and can effectively ensure the processing accuracy of the parts.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed:

[0005] A multi-angle grinding fixture for flat parts is characterized by comprising: a base having multiple spaced positioning inclined surfaces on its top for supporting the bottom surface of the flat part, each positioning inclined surface having the same orientation and different inclination angles, each positioning inclined surface having several strong magnets, the top surface of which is flush with or lower than the corresponding positioning inclined surface; the base is used to connect to the platform of a grinding machine.

[0006] The strong magnet has a cuboid structure, with multiple parallel slots on each positioning slope, and each slot contains a detachable strong magnet.

[0007] A support bar is provided in the middle section of the strip groove to support the strong magnet. The length of the support bar is less than the length of the strong magnet. The distance between the top surface of the support bar and the positioning inclined surface is less than or equal to the thickness of the strong magnet. A screw rod parallel to the strip groove passes through the support bar. Wedge blocks are slidably provided at both ends of the strip groove. The wedge-shaped surfaces of the wedge blocks slide in contact with the bottom edges of both ends of the strong magnet. The threads at both ends of the screw rod turn in opposite directions, and the two ends of the screw rod pass through the two wedge blocks respectively.

[0008] The advantages of this invention are as follows: This solution does not require adjustment of the grinding machine platform, which not only allows for quick switching of the machining surface of the part and has high clamping efficiency, but is also unaffected by adjustment accuracy, thus effectively ensuring the dimensional accuracy of the part.

[0011] Figure 2 A cross-sectional view of a preferred mounting structure for a strong magnet is shown.

[0012] Figure 3 An exploded view of a preferred mounting structure for a strong magnet is shown.

[0013] The markings in the diagram are: base-1, positioning slope-11, waste guide channel-12, strip channel-13, support bar-14, strong magnet-2, screw-3, and wedge-shaped block-4. Detailed Implementation

[0014] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figures 1 to 3 As shown, a multi-angle grinding fixture for flat parts includes: a base 1, the top of which has multiple spaced positioning inclined surfaces 11 for supporting the bottom surface of the flat part. Each positioning inclined surface 11 has the same orientation and a different inclination angle. Each positioning inclined surface 11 is provided with several strong magnets 2, the top surface of which is flush with or lower than the corresponding positioning inclined surface 11. The base 1 is used to connect to the platform of the grinding machine. Specifically, the base 1 can be locked onto the platform by screws, or the base 1 can be pressed onto the platform by levers or pressure bars or pressure plates.

[0016] In use, the flat part is placed on the positioning inclined surface 11 and the flat part is attracted and fixed by the strong magnet 2. Then, grinding can be carried out. When it is necessary to grind the flat part at different angles, simply place the part on the positioning inclined surface 11 with the appropriate angle. This method does not require adjustment of the grinding machine platform, which not only allows for quick switching and has high clamping efficiency, but is also not affected by adjustment accuracy, which can effectively ensure the dimensional accuracy of the part.

[0017] Preferred, such as Figure 1 , Figure 3 As shown, the base 1 is provided with a waste guide groove 12 at the lower edge of the positioning inclined surface 11 for collecting waste. As a further preferred embodiment, the waste guide groove 12 is an inclined groove structure to facilitate the discharge of the collected waste.

[0018] Preferred, such as Figure 1 , Figure 3As shown, the strong magnet 2 has a cuboid structure, and multiple parallel strip grooves 13 are provided on each positioning inclined surface 11. Each strip groove 13 is equipped with a detachable strong magnet 2 so that it can be replaced after the magnetism of the strong magnet 2 decreases.

[0019] Further preferred, such as Figure 2 , Figure 3 As shown, a support bar 14 is provided in the middle section of the strip groove 13 to support the strong magnet 2. The length of the support bar 14 is less than the length of the strong magnet 2. The distance between the top surface of the support bar 14 and the positioning inclined surface 11 is less than or equal to the thickness of the strong magnet 2, so as to meet the requirement that the top surface of the strong magnet 2 is flush with or lower than the corresponding positioning inclined surface 11. A screw 3 parallel to the strip groove 13 is passed through the support bar 14. Wedge blocks 4 are slidably provided at both ends of the strip groove 13. The wedge surface of the wedge block 4 is in sliding contact with the bottom edge of both ends of the strong magnet 2. The threads at both ends of the screw 3 are turned in opposite directions, and the two ends of the screw 3 pass through the two wedge blocks 4 respectively. With the above structural design, when disassembling the strong magnet 2, it is only necessary to rotate the screw 3, and at the same time, the two wedge blocks 4 move towards the middle. The wedge surfaces on both sides can be used to lift the strong magnet 2 up towards the top of the strip groove 13, so as to facilitate the removal of the strong magnet 2. Compared with the method of disassembling the strong magnet 2 by knocking, this solution is faster, less labor-intensive and safer, and can effectively prevent damage to the positioning inclined surface 11 and the strong magnet 2.

[0020] Preferred, such as Figure 2 As shown, the wedge-shaped surface of the wedge block 4 is inclined towards the upper part of the middle of the strip groove 13. The lower edge of the wedge-shaped surface is lower than the height of the top surface of the support bar 14, and the upper edge of the wedge-shaped surface is flush with the positioning inclined surface 11. In this way, the strong magnet 2 can be completely pushed out of the strip groove 13 directly by the wedge block 4.

[0021] More preferably, both ends of the screw 3 are provided with hexagonal prisms to facilitate the connection of a sleeve or wrench to rotate the screw 3.

[0022] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
