Description

Technical Field

[0001] This utility model relates to the field of machining tooling, specifically a clamping tool for fixing a grinding wheel cutting machine. Background Technology

[0002] Handheld air grinders are primarily used for grinding, polishing, and cutting hard materials such as metal, stone, and glass. In the machining field, by selecting the appropriate cutting wheel, straight-line cutting, curved cutting, and finishing can be easily performed. This function has wide applications in construction, metal processing, and handicrafts. Furthermore, handheld air grinders, due to their portability and flexibility, are suitable for small-scale metal processing and detail finishing, and are particularly suitable for cutting small, thin-walled parts.

[0003] When using a handheld grinder to cut workpieces, the grinder is held and fixed by hand. When the grinder comes into contact with the workpiece, it will vibrate, which will cause the cut surface of the workpiece to be uneven. Sometimes it may even affect the appearance and performance of the parts.

[0004] The technical solution of existing technology 1 is as follows:

[0005] The workpiece to be cut is processed manually by hand using a handheld grinder.

[0006] The disadvantages of existing technology 1 are:

[0007] Cutting workpieces directly with a handheld grinder can result in uneven surfaces due to the vibration of the grinder during the cutting process and the lack of stability when held manually. Sometimes, when a workpiece needs to be machined into a horizontal surface, directly using a handheld grinder can even result in a slanted surface, thus affecting the quality and usability of the parts.

[0008] The technical solution of existing technology 2 is as follows:

[0009] It is placed on a specialized cutting machine for processing.

[0010] The disadvantages of the existing technology 2 are:

[0011] 1. While placing the parts on a cutting machine for processing can ensure the cutting quality of the parts, for small workpieces, the workpiece still needs to be clamped and fixed before cutting, which is relatively inefficient.

[0012] 2. Professional cutting machines have higher processing costs and it is difficult to control the processing costs of parts. Utility Model Content

[0013] This utility model provides a clamping fixture for fixing a grinding wheel cutting machine. Its purpose is to overcome the shortcomings of the prior art, effectively ensure the levelness of the workpiece cutting surface, improve the flatness of the cutting surface, and reduce costs.

[0014] The technical solution adopted by this utility model to solve its technical problem is:

[0015] A clamping fixture for fixing a grinding wheel cutting machine, characterized in that:

[0016] The lower tooling base is placed on the worktable;

[0017] Two tooling columns are fixedly connected to the lower tooling base; each tooling column corresponds to a stud, and the stud passes through the vertical rectangular through hole opened in the tooling column;

[0018] The grinding wheel is located in the middle of two tooling columns. The heads of the studs on both sides clamp the grinding wheel in the middle. Each stud corresponds to two locking nuts. The two locking nuts are screwed onto both sides of the stud and press against the two sides of the tooling columns.

[0019] Rollers are installed at the four corners of the lower tooling base to support the worktable.

[0020] The tooling column is welded to the upper tooling base. After the bolt passes through the through hole provided in the upper tooling base, it is screwed into the threaded hole at the corresponding position in the lower tooling base, thus fixing the upper tooling base and the tooling column to the lower tooling base.

[0021] The grinding wheel of the grinding machine extends out from the side of the lower tooling base.

[0022] The advantages of this utility model are:

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] like Figure 1 , Figure 2 As shown:

[0032] The lower fixture base 2 is a rectangular plate with a certain thickness. Rollers 3 are installed at the bottom of the lower fixture base 2, and at its four corners to ensure even distribution, supporting the worktable 1. In this way, the lower fixture base 2 can slide on the worktable 1 via the rollers 3.

[0033] The upper fixture base 4 is a square plate with a certain thickness, and four through holes are pre-machined on the plane of the upper fixture base 4.

[0034] The tooling column 6 is a rectangular plate with a certain thickness. The tooling column 6 is fixedly connected to the upper tooling base 4 by welding. Four bolts are passed through four pre-machined through holes 41 on the flat surface of the upper tooling base 4, and then screwed into the corresponding pre-machined threaded holes 21 on the lower tooling base 2. In this way, the upper tooling base 4 and the tooling column 6 are fixed to the lower tooling base 2.

[0035] Depend on Figure 1It can be seen that this view Figure 1 It uses two upper tooling bases 4 and two tooling columns 6, and the two upper tooling bases 4 and two tooling columns 6 are symmetrically installed on the lower tooling base 2.

[0036] A vertical rectangular through hole 61 is pre-drilled in the middle of the tooling column 6. The width of the vertical rectangular through hole 61 is greater than the diameter of the stud 7. The stud 7 is passed through the pre-drilled vertical rectangular through hole 61 in the middle of the tooling column 6. The locking nut 8 and locking nut 9 are respectively screwed onto the two sides of the stud 7 and pressed against the two sides of the tooling column 6. The vertical rectangular through hole 61 allows the stud 7 to move up and down to adjust its position according to the height to be cut on the workpiece before fixing it.

[0037] Place the grinding wheel 10 between the two tooling columns 6. Adjust the extension length of the studs 7 to control the head of the studs 7 to contact the outer shell of the grinding wheel 10. Finally, adjust the height of the grinding wheel 11 according to the height of the plane of the workpiece 22 to be cut. After confirming the height, tighten the locking nuts 8 and 9 and press the tooling columns 6. The heads of the studs 7 on both sides clamp the grinding wheel 10 in the middle, thus clamping and fixing the grinding wheel 10.

[0038] Figure 2 It can be seen that the upper tooling base 4 is fixed to the front end of the lower tooling base 2, and the grinding wheel 11 of the grinding machine extends out of the side of the lower tooling base 2. At the same time, the installation position of the bolts that fix the upper tooling base 4 can be seen.

[0039] After the grinding wheel 10 is fixed, you can hold the lower tooling base 2 with your hand. Since there are rollers 3 on the lower tooling base 2, you can push the lower tooling base 2 to move back and forth on the worktable 1. Since the height of the grinding wheel 10 is fixed, the cut surface is also horizontal. And according to the experimental results, the processed surface is also very flat.

[0040] Currently, when cutting thin-walled workpieces, the workpiece is cut directly by hand with a grinding wheel. Because there is vibration during the cutting process, the vibration is also transmitted to the operator's arm, which will result in the cut surface not being flat or not being horizontal.

[0041] This invention allows a grinding wheel machine to be fixed on a support frame, with rollers underneath. The workpiece can be cut by moving the support frame back and forth, which ensures the quality of the cut surface and saves on the processing costs of a traditional cutting machine.

[0042] The fixture's upright column 6 has a rectangular through hole in the center, allowing the stud to be adjusted in height according to the required cutting height of the workpiece. Therefore, this fixture is suitable for cutting workpieces within a certain size range, offering greater versatility.

[0043] The various embodiments described in this specification are presented in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
