Description

Technical Field

[0001] This utility model relates to the field of grinding machine fixture design, and in particular to a fixture for machining beveled parts. Background Technology

[0002] In the chamfering and grinding of metal parts, a sine table is used to clamp the metal parts and magnetically fix them to the worktable of the grinding machine. The sine table is an important fixture in grinding, and its main function is to adjust the angle using the sine principle to cooperate with the grinding machine for grinding. Its typical structure includes an integrated magnetic base, precision rollers, and a fixing device. Stability is ensured by the uniform distribution of magnetic force and the high hardness of the base material. Sine tables are widely used in mold manufacturing, machining, and other fields.

[0003] For example, the prior art (announcement number: CN216608952U, announcement date: 2022.05.27) discloses a sinusoidal angle worktable, which determines the angle through an indexing plate, and then fixes the device by replacing the corresponding support block, adjustment block, rotating support shaft and pressure block, and finally by bolts through the first fixing hole and the second fixing hole. Finally, the sinusoidal angle worktable can be clamped onto the processing equipment for processing. It does not require changing multi-axis equipment for processing, the operation is simple and the processing cost is low.

[0004] However, existing sine table can only clamp one metal part at a time. For mass-produced precision parts, each precision part needs to be recalibrated when clamping, resulting in low production efficiency. If there is an error in the calibration, the chamfer angle of each precision part will be inconsistent, resulting in poor product consistency.

[0005] Therefore, it is necessary to design a jig for batch chamfering of precision metal parts to solve the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0007] A jig for machining beveled parts includes a magnetic block and a strip jig table, wherein the strip jig table is magnetically attached to the magnetic block; The upper side of the magnetic block is formed with a right-angle limiting edge, the corner position of the inner side of the right-angle limiting edge is formed with a first concave circular groove, and the bottom edge of the inner side of the right-angle limiting edge and the magnetic block are formed with a second concave circular groove. One end of the strip fixture table is fitted into the right-angle limiting edge through the first concave circular groove and the second concave circular groove. The upper side of the strip-shaped fixture table is formed with several right-angle positioning transverse grooves arranged in an equidistant array. Several vacuum holes are formed on both sides of the right-angle limiting edge, and the inner end of the vacuum hole is connected to the second concave circular groove.

[0008] Furthermore, a sealing cover is installed on the outer side of the right-angle limiting edge, and a through channel is formed inside the sealing cover. The outer end of the vacuum hole is connected to the through channel.

[0009] Furthermore, a vacuum tube is formed on the outer side of the sealing cap, and the inner end of the vacuum tube is connected to the through channel.

[0010] Furthermore: a sealing groove is formed on the inner side of the sealing cover, the sealing groove is located on the outer edge of the through channel, and sealant is filled between the sealing groove and the magnetic block.

[0011] Furthermore, the outer side of the sealing cover is formed with at least three right-angled edges, which are fixedly mounted on the magnetic block by screws.

[0012] Furthermore, a third concave circular groove is formed at the corner position inside the right-angle positioning groove.

[0013] Furthermore: the bottom edge of the right-angle positioning groove is set higher than the upper surface of the right-angle limiting edge.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Use the right-angle limiting edge on the magnetic block to provide positioning for the strip fixture stage, ensuring that the direction of the strip fixture stage is parallel to the magnetic block, thus achieving precise positioning of the strip fixture stage; 2. Before magnetic fixation, use vacuuming to ensure that one end of the strip fixture table fits into the right-angle limiting edge through the first and second concave circular grooves, thus ensuring its installation accuracy; 3. Place the magnetic block on the base of the grinding machine for magnetic fixation. During processing, place the precision parts one by one into several right-angle positioning slots on the strip jig table to achieve batch chamfering of precision parts. In this invention, since the direction of the right-angle positioning groove is pre-machined on the strip fixture table, the grinding machine can perform bevel grinding operation on a batch of precision parts, ensuring consistency during batch production and accelerating production efficiency.

[0024] like Figure 1-4 As shown, a part bevel machining fixture of the present invention includes a magnetic block 1 and a strip fixture table 2, wherein the strip fixture table 2 is magnetically attached to the magnetic block 1; The upper side of the magnetic block 1 is formed with a right-angle limiting edge 3, the corner position of the inner side of the right-angle limiting edge 3 is formed with a first concave circular groove 4, and the bottom edge of the inner side of the right-angle limiting edge 3 and the magnetic block 1 are formed with a second concave circular groove 5. One end of the strip fixture table 2 is fitted into the right-angle limiting edge 3 through the first concave circular groove 4 and the second concave circular groove 5. The upper side of the strip fixture table 2 is formed with several right-angle positioning transverse grooves 6 arranged in an equidistant array; Several vacuum holes 7 are formed on both sides of the right-angle limiting edge 3, and the inner end of the vacuum hole 7 is connected to the second concave circular groove 5. The principle is as follows: the right-angle limiting edge 3 on the magnetic block 1 provides positioning for the strip fixture table 2, ensuring that the direction of the strip fixture table 2 is parallel to the magnetic block 1. Before magnetic fixation, a vacuum is used to make one end of the strip fixture table 2 fit into the right-angle limiting edge 3 through the first concave circular groove 4 and the second concave circular groove 5, ensuring its installation accuracy. Finally, the magnetic block 1 is placed on the base of the grinding machine for magnetic fixation. During processing, precision parts are placed one by one into several right-angle positioning horizontal grooves 6 on the strip fixture table 2. Since the direction of the right-angle positioning horizontal grooves 6 is pre-machined on the strip fixture table 2, the grinding machine can perform bevel grinding operation on a batch of precision parts, ensuring the consistency of batch production and speeding up production efficiency.

[0025] Furthermore: a sealing cover 8 is installed on the outer side of the right-angle limiting edge 3, and a through channel 9 is formed inside the sealing cover 8. The outer end of the vacuum hole 7 is connected to the through channel 9. The through channel 9 inside the sealing cover 8 can be used to connect several vacuum holes 7 to each other, thereby facilitating the vacuuming operation.

[0026] Furthermore, a vacuum tube 10 is formed on the outer side of the sealing cover 8, and the inner end of the vacuum tube 10 is connected to the through channel 9; the vacuum tube 10 can be used to evacuate several vacuum holes 7, which is convenient for actual use and allows strip jig tables 2 of different sizes to be quickly installed on the magnetic block 1 and the right angle limiting edge 3.

[0027] Furthermore: the inner side of the sealing cover 8 is formed with a sealing groove 11, which is located on the outer edge of the through channel 9. The sealing groove 11 and the magnetic block 1 are filled with sealant; this can reduce the occurrence of air leakage and allow the negative pressure to be stable in the second concave circular grooves 5 on both sides, thereby adsorbing the strip fixture 2 to be quickly installed in place on the inner side of the right angle limiting edge 3.

[0028] Furthermore, the outer side of the sealing cover 8 is formed with at least three right-angled edges 12, which are fixedly mounted on the magnetic block 1 by screws, making the installation of the sealing cover 8 more secure and reliable.

[0029] Furthermore, a third concave circular groove 13 is formed at the corner position inside the right-angle positioning horizontal groove 6; the third concave circular groove 13 is used to realize the rapid installation of precision parts in the right-angle positioning horizontal groove 6, avoid the installation tilting and offset, and ensure the consistency of the chamfering operation.

[0030] Furthermore, the bottom edge of the right-angle positioning groove 6 is set higher than the upper surface of the right-angle limiting edge 3 to ensure that the right-angle limiting edge 3 will not affect the use of the strip fixture table 2.

[0031] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
