Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a multi-purpose tooling and fixture for horizontal machining centers. Background Technology
[0002] Tooling fixtures are specialized process equipment used in the mechanical manufacturing industry to fix, position, and support workpieces to ensure machining accuracy and improve production efficiency. Their core function is to maintain a stable posture of the workpiece during machining through physical constraints and precise positioning, thus meeting the relative motion requirements between the tool and the workpiece.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the tooling fixtures used in traditional horizontal machining centers are mostly fixed. After the workpiece is machined on one side, it needs to be disassembled and re-clamped on the other side. The switching time between processes is long, and multiple clamping can easily lead to the accumulation of positioning errors. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the tooling fixtures used in traditional horizontal machining centers are mostly fixed and cannot drive the workpiece to rotate directly. To this end, we propose a multi-purpose tooling fixture for horizontal machining centers.
[0005] To achieve the above objectives, this application adopts the following technical solution: It includes a first base; a device frame is slidably connected to the top of the first base; a processing device is slidably connected to one side of the device frame; a second base is fixedly connected to one end of the first base; a processing table is slidably connected to the top of the second base; two positioning frames are mounted on the top of the processing table; a rotating shaft is rotatably connected to the opposite surfaces of the two positioning frames; a rotating block is fixedly connected to one side of the rotating shaft; a clamping body is fixedly connected to the side of the rotating block away from the rotating shaft; an annular block is fixedly connected to the side of the positioning frame near the clamping body; the rotating block rotates inside the annular block; two circumferentially symmetrically formed holes are formed on the surface of the annular block; a pressing block is slidably connected inside the circular hole; several circular grooves are formed on the surface of the rotating block; a first spring is fixedly connected inside the circular groove; one end of the first spring is connected to the inner wall of the circular groove; the other end of the first spring is fixedly connected to a limiting block; and the surface of the limiting block is slidably connected to the inside of the circular hole.
[0006] Preferably, the annular block has an annular groove on the side near the fixture body, and a sliding block is fixedly connected to the side of the fixture body near the positioning frame, with the surface of the sliding block slidably connected to the inside of the annular groove.
[0007] Preferably, a second spring is slidably connected to the surface of the press block, one end of the second spring is fixedly connected to the end of the press block near the limiting block, and the other end of the second spring is fixedly connected to the inside of the circular hole.
[0008] Preferably, an annular limiting piece is fixedly connected to the surface of the limiting block, and the surface of the annular limiting piece is slidably connected to the inside of the circular groove.
[0009] Preferably, the top and bottom of the block are provided with square grooves, and the top and bottom of one end of the round hole are fixedly connected with square sliders, the surface of the square sliders being slidably connected to the inside of the square grooves.
[0010] Preferably, both the annular groove and the sliding block have T-shaped cross-sections.
[0011] Preferably, the included angle between two adjacent limiting blocks is ninety degrees.
[0012] The technical effects and advantages of this utility model are as follows: In this invention, by rotating the rotating block on one side of the positioning frame, the rotation of the rotating block drives the main body of the fixture to rotate. The rotation of the main body of the fixture can cause the material to flip. By pressing the button, the button pushes the limiting block out of the inside of the circular hole. At this time, the limiting block returns to the inside of the circular groove, and the limiting of the rotating block is also released. At this time, the main body of the fixture can be rotated, causing the main body of the fixture to drive the workpiece to flip. When it flips to 90 degrees, the elasticity of the first spring pushes the limiting block back into the inside of the circular hole, so that the rotating block is limited again. By causing the workpiece to flip by flipping the fixture body, the workpiece can be processed on multiple sides in one clamping, thereby significantly reducing the number of clamping operations required during the processing of the workpiece. This approach not only effectively avoids the problem of accumulated positioning errors caused by multiple clamping operations, but also greatly improves the overall processing efficiency, ensures the accuracy and consistency of workpiece processing, and thus improves production efficiency and product quality.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.
[0016] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a multi-purpose tooling fixture for a horizontal machining center, including a first base 1; a machine frame 3 is slidably connected to the top of the first base 1, a machining device 4 is slidably connected to one side of the machine frame 3, a second base 5 is fixedly connected to one end of the first base 1, a machining table 6 is slidably connected to the top of the second base 5, two positioning frames 7 are mounted on the top of the machining table 6, a rotating shaft 8 is rotatably connected to the opposite surfaces of the two positioning frames 7, a rotating block 9 is fixedly connected to one side of the rotating shaft 8, and a fixture body 10 is fixedly connected to the side of the rotating block 9 away from the rotating shaft 8. A ring block 11 is fixedly connected to one side of the clamp body 10. The rotating block 9 rotates inside the ring block 11. Two circular holes 12 are symmetrically opened on the surface of the ring block 11. A push block 13 is slidably connected inside the circular holes 12. Several circular grooves 14 are opened on the surface of the rotating block 9. A first spring 15 is connected inside the circular groove 14. One end of the first spring 15 is connected to the inner wall of the circular groove 14. The other end of the first spring 15 is fixedly connected to a limit block 16. The surface of the limit block 16 can slide with the inside of the circular hole 12. The included angle between two adjacent limit blocks 16 is ninety degrees. Specifically: By rotating the rotating block 9 on one side of the positioning frame 7, the rotation of the rotating block 9 drives the fixture body 10 to rotate. The rotation of the fixture body 10 can cause the workpiece to flip. By pressing the button 13, the button 13 pushes the limiting block 16 out of the inside of the circular hole 12. At this time, the limiting block 16 returns to the inside of the circular groove 14, and the limiting of the rotating block 9 is also released. At this time, the fixture body 10 can be rotated, causing the fixture body 10 to cause the material to flip. When it flips to ninety degrees, the elasticity of the first spring 15 pushes the limiting block 16 back into the inside of the circular hole 12, so that the rotating block 9 is limited again. By causing the fixture body 10 to flip and drive the workpiece to flip, the workpiece can be processed on multiple sides in one clamping, thereby significantly reducing the number of clamping operations required during the processing. This method not only effectively avoids the problem of accumulated positioning errors caused by multiple clamping operations, but also greatly improves the overall processing efficiency, ensures the accuracy and consistency of workpiece processing, and thus improves production efficiency and product quality.
[0017] Reference Figure 1 - Figure 5 As shown, in this embodiment: an annular block 11 has an annular groove 17 on the side near the clamp body 10; a sliding block 18 is fixedly connected to the side of the clamp body 10 near the positioning frame 7; the surface of the sliding block 18 is slidably connected to the inside of the annular groove 17; a second spring 19 is slidably connected to the surface of the push block 13; one end of the second spring 19 is fixedly connected to the end of the push block 13 near the limiting block 16; the other end of the second spring 19 is fixedly connected to the inside of the round hole 12; an annular limiting piece 20 is fixedly connected to the surface of the limiting block 16; the surface of the annular limiting piece 20 is slidably connected to the inside of the circular groove 14; square grooves 21 are provided at the top and bottom of the push block 13; square sliders 22 are fixedly connected to the top and bottom of one end of the round hole 12; the surface of the square sliders 22 is slidably connected to the inside of the square groove 21; the cross-sections of the annular groove 17 and the sliding block 18 are both T-shaped. Specifically: by allowing the sliding block 18 to slide inside the annular groove 17, and since both the annular groove 17 and the sliding block 18 have T-shaped cross sections, the fixture body 10 can be made more stable when flipping, providing guidance for the movement of the fixture body 10. By setting the second spring 19, the elasticity of the second spring 19 abuts against the button 13, which can automatically reset the button 13. By setting the annular limiting piece 20, the movement of the limiting block 16 can be restricted, preventing the limiting block 16 from coming out of the circular groove 14, ensuring the stability of the limiting of the rotating block 9. By allowing the square slider 22 to slide inside the square groove 21, unnecessary displacement of the button 13 inside the circular hole 12 can be prevented.
[0018] Working principle: By rotating the rotating block 9 on one side of the positioning frame 7, the rotation of the rotating block 9 drives the clamp body 10 to rotate. The rotation of the clamp body 10 can cause the material to flip. By pressing the button 13, the button 13 pushes the limiting block 16 out of the inside of the circular hole 12. At this time, the limiting block 16 returns to the inside of the circular groove 14, and the limiting of the rotating block 9 is also released. At this time, the clamp body 10 can be rotated, causing the clamp body 10 to cause the material to flip. When it flips to ninety degrees, the elasticity of the first spring 15 pushes the limiting block 16 back into the inside of the circular hole 12, so that the rotating block 9 is limited again. By moving the sliding block 18... The sliding block 18 slides inside the annular groove 17, and both the annular groove 17 and the sliding block 18 have T-shaped cross sections, which makes the clamp body 10 more stable when flipping and provides guidance for the movement of the clamp body 10. By setting the second spring 19, the elasticity of the second spring 19 abuts against the button 13, which can make the button 13 automatically reset. By setting the annular limiting piece 20, the movement of the limiting block 16 can be restricted, preventing the limiting block 16 from coming out of the circular groove 14 and ensuring the stability of the limiting of the rotating block 9. By making the square slider 22 slide inside the square groove 21, unnecessary displacement of the button 13 inside the circular hole 12 can be prevented.
[0019] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
