[0022] See Figures 1 to 4 As shown, a multi - unit adjustable - stroke double - sided V - type fixture includes a horizontally placed fixed frame 1 and a movable frame 2 slidably inserted into the fixed frame 1. A cavity corresponding to the movable frame 2 is provided inside the fixed frame 1. A plurality of first V - type grooves 21 and second V - type grooves 22 are respectively provided on the opposite side surfaces of the movable frame 2. The plurality of first V - type grooves 21 and second V - type grooves 22 are arranged in the vertical direction. A plurality of abutting bolts 3 are provided inside the fixed frame 1 opposite to the first V - type grooves 21 and / or the second V - type grooves 22.

[0023] In this technical solution, the fixed frame and the movable frame are made of materials that can be adsorbed by the magnetic disk of a surface grinder. They are adsorbed and fixed by the magnetic disk of the surface grinder together with the workpiece to be ground, without the need for external tooling, etc. Both the first V - type groove and the second V - type groove are V - type opening grooves with an angle of 90°, and are arranged back - to - back, that is, the opening directions of the first V - type groove and the second V - type groove are opposite, which improves the utilization rate of the movable frame. The depths of the first V - type groove and the second V - type groove are different, which can meet the clamping requirements of multiple and different - specification workpieces.

[0024] Exemplarily, see Figures 1 to 4 As shown, a plurality of sliding teeth 23 respectively protrude from both end faces of the movable frame 2 perpendicular to the side surfaces where the first V - type grooves 21 and the second V - type grooves 22 are located. The adjacent sliding teeth 23 are arranged at intervals. The inner wall of the cavity is provided with chutes corresponding to the sliding teeth 23.

[0025] In this technical solution, the movable frame is a block structure, the bottom surface of which is attached to the surface of the disk, and the top surface can be marked by laser engraving or other means to distinguish the front and back sides and identify the model and specifications, etc. A number of sliding teeth protrude from the two end surfaces with shorter lengths to cooperate with the slide grooves on the inner wall of the cavity to achieve the sliding installation of the movable frame. After the sliding teeth are engaged with the corresponding slide grooves, the movable frame is completely fixed in the horizontal direction without the need to adjust the reference, thereby improving the clamping efficiency. At the same time, the position of the movable frame can be adjusted by docking different sliding teeth and slide grooves, thereby adjusting the clamping stroke range and expanding the scope of application.

[0026] For example, see Figures 1 to 4 As shown, the sliding teeth 23 are integrally formed with the movable frame 2 .

[0027] In this technical solution, the sliding teeth and the sliding grooves are both vertically arranged, and adjacent sliding teeth are spaced apart. The sliding teeth and the sliding grooves have a mortise and tenon structure, and the structure is stable. The sliding teeth are directly formed on the two end surfaces of the movable frame by machining to ensure accuracy.

[0028] For example, see Figures 1 to 4 As shown, the first V-shaped groove 21 and the second V-shaped groove 22 are staggered.

[0029] In this technical solution, the first V-shaped groove and the second V-shaped groove are respectively formed in the two longer side surfaces of the movable frame, and the angular bisectors of the first V-shaped groove and the second V-shaped groove are perpendicular to the side surfaces on which they are located, and the angular bisectors of the first V-shaped groove and the second V-shaped groove are not coplanar, thereby improving the space utilization of the movable frame and ensuring the overall strength of the movable block.

[0030] For example, see Figure 1 and Figure 2 As shown, the fixing frame 1 is a hollow square-shaped structure formed by two side plates 11 and two end plates 12 , wherein the abutment bolts 3 are respectively arranged in the two end plates 12 and face the first V-shaped groove 21 and the second V-shaped groove 22 respectively.

[0031] In this technical solution, the fixed frame is a U-shaped structure, and its internal hollow space is used as a cavity for setting up the movable frame. The inner walls of the two side plates are respectively processed with sliding grooves, and a number of threaded holes corresponding to the abutment bolts are respectively arranged in the two end plates. The central axis of the threaded hole is horizontally arranged and is located in the angular bisector plane corresponding to the first V-shaped groove or the second V-shaped groove, that is, the abutment bolt is arranged perpendicular to the workpiece, and the first V-shaped groove or the second V-shaped groove can respectively place workpieces of different specifications.

[0032] For example, see Figure 1 As shown, the two side plates 11 and the end plate 12 are integrally formed.

[0033] In this technical solution, the fixing frame is made of a whole steel plate or the like through processing, and the cavity and the sliding groove are both machined to ensure accuracy. The side plate and the end plate are integrally formed to ensure the connection strength.

[0034] Exemplarily, refer to Figure 2 As shown, the two side plates 11 and the end plate 12 are of a split structure.

[0035] In this technical solution, the side plate and the end plate are processed separately and spliced by bolts or the like, reducing the processing materials and difficulty and lowering the production cost.

[0036] Exemplarily, refer to Figure 3 and Figure 4 As shown, the fixing frame 1 is a trough-shaped structure formed by two side plates 11 and one end plate 12. Among them, the abutting bolts 3 are respectively arranged in the end plate 12 and are respectively opposite to the first V-shaped groove 21 and / or the second V-shaped groove 22.

[0037] In this technical solution, the fixing frame is of a trough-shaped structure, and the internal opening groove is used as a cavity. The inner walls of the two side plates are respectively machined with sliding grooves, and threaded holes respectively opposite to the first V-shaped groove and the second V-shaped groove are arranged in the end plate for the use of the abutting bolts. When the first V-shaped groove or the second V-shaped groove is close to the end plate, the corresponding abutting bolts are used. When the distance between adjacent threaded holes is small and affects the strength between the threaded holes, two fixing frames are used corresponding to one movable frame, that is, the abutting bolts in one fixing frame are used corresponding to the first V-shaped groove, and the abutting bolts in the other fixing frame are used corresponding to the second V-shaped groove, improving the utilization rate of the movable frame.

[0038] In summary, the structure of the multi-unit adjustable-stroke double-sided V-shaped fixture is simple. The two side surfaces of the movable frame are respectively provided with a first V-shaped groove and a second V-shaped groove, improving the utilization rate of the movable frame. The opening angles of the first V-shaped groove and the second V-shaped groove are the same or different to meet the clamping requirements of multiple and different specifications of workpieces.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0040] The above are only specific embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
