Utility Model Content The purpose of this utility model is to provide a machining clamping and positioning fixture to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a machining clamping and positioning fixture, a base, and a machining module. The base has two parallel sliding grooves that run through it. The machining module is mounted on the sliding grooves via a sliding module and can move back and forth along the sliding grooves. The base is a casting. The machining module includes a finishing module and a roughing module that can be interchanged. Both the finishing module and the roughing module are composed of two symmetrical "L"-shaped components with two protrusions at the bottom. The size and shape of the protrusions match the sliding grooves.

[0005] As a further description of the above solution, each of the "L"-shaped components of the finishing module has a groove at its top, and a longitudinal positioning hole perpendicular to the upper surface is formed inside the groove, with the positioning holes being spaced at the same distance.

[0006] As a further description of the above solution, each of the "L"-shaped components of the finishing module has a horizontal positioning hole perpendicular to the side at its top, and the positioning holes are spaced at the same distance.

[0007] As a further description of the above solution, a positioning module is installed in the horizontal positioning hole, and the two are fixedly connected by screws, while a positioning screw is installed in the vertical positioning hole.

[0008] As a further description of the above scheme, each of the "L"-shaped components of the roughing module has height adjustment holes equidistantly spaced at its top.

[0009] As a further description of the above solution, a dustproof bolt or a height adjustment bolt can be installed in the height adjustment hole depending on the usage conditions.

[0010] As a further description of the above scheme, the finishing module and the roughing module are made of wear-resistant steel with high strength.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes freely replaceable processing modules, solving the problem in the prior art that requires replacing the entire fixture or moving the workpiece to be processed to adapt to roughing and finishing, which leads to a decrease in work efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This embodiment provides a machining clamping and positioning fixture, including a base 1 and a machining module. The base 1 has two parallel sliding grooves 1.1 that run through it. The machining module is mounted on the sliding grooves via a sliding module 4 and can move back and forth along the grooves to accommodate workpieces of different sizes. The base 1 is a casting, such as gray cast iron or ductile iron, which can provide good load-bearing capacity and shock absorption, effectively supporting the workpiece. The machining module includes a finishing module 2 and a roughing module 3 that can be interchanged. The two modules can be interchanged to perform finishing and roughing without replacing the entire fixture or transferring the workpiece. The finishing module 2 and the roughing module 3 are both composed of two symmetrical "L"-shaped components with two protrusions at the bottom. The size and shape of the protrusions match the sliding grooves 1.1, positioning the machining module in the grooves so that it can move back and forth along them. The finishing module 2 and the roughing module 3 are made of high-strength wear-resistant steel, such as carbon structural steel and 45 steel. Because of their high strength, high hardness and good wear resistance, they are very suitable as machining fixtures for high-load machining.

[0016] Specifically, each of the "L"-shaped components of the finishing module 2 has a groove on its top, and a longitudinal positioning hole 2.3 perpendicular to the upper surface is opened inside the groove. The positioning holes are spaced at the same distance. Each side of the "L"-shaped component has a transverse positioning hole 2.4 perpendicular to the side. A positioning module is installed in the transverse positioning hole 2.4. The two are fixedly connected by screws. A positioning screw 2.2 is installed in the longitudinal positioning hole 2.3 to cooperate with each other to achieve precise positioning of the workpiece to be processed. Specifically, each of the "L"-shaped components of the roughing module 3 has height adjustment holes 3.1 equidistantly spaced on its top. Depending on the usage, dustproof bolts 3.2 or height adjustment bolts 3.3 can be installed in the height adjustment holes 3.1. When the height needs to be adjusted, the height adjustment bolts 3.3 are installed in the height adjustment holes 3.1, while when not in use, the dustproof bolts 3.2 can be installed to prevent dust from entering the holes.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
