DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 7 As shown, an embodiment of the present invention provides a new type of grooved machining fixture, including a mounting table 1 and a clamping mold 2, the mounting table 1 is provided with a horizontally arranged L-shaped mounting plate 11, the L-shaped mounting plate 11 is provided with a mechanical clamping mechanism 3 for clamping the workpiece, the mechanical clamping mechanism 3 and the L-shaped mounting plate 11 are slidably fitted together, the mechanical clamping mechanism 3 is provided with two clamping ends 4, the two clamping ends 4 are provided with a clamping and flipping mechanism 5 for driving the workpiece to flip, the clamping and flipping mechanism 5 is rotatably connected to the clamping end 4, the clamping molds 2 are respectively arranged on the clamping and flipping mechanisms 5, and the clamping mold 2 and the clamping and flipping mechanism 5 are detachably connected.

[0020] In the process of clamping the workpiece, the mechanical clamping mechanism 3 drives the clamping mold 2 to clamp the workpiece, and in the process of clamping, the clamping flipping mechanism 5 can drive the position of the workpiece to flip and rotate, so as to perform processing operations on different positions on the workpiece. The clamping fixture can clamp and fix different types of workpieces according to the needs of the workpiece, and can fix circular, square or inclined surface-shaped and polygonal workpieces, so as to be suitable for fixing different workpieces, thereby improving the applicability of the device.

[0021] In this preferred embodiment, the mechanical clamping mechanism 3 includes a clamping cylinder 30, a movable plate 31 and a slide rail 32. Two slide rails 32 are provided at the bottom of the movable plate 31. The movable plate 31 moves on the L-shaped mounting plate 11 through the two slide rails 32. The slide rails 32 are horizontally arranged on the side walls of the L-shaped mounting plate 11. The clamping cylinder 30 is horizontally arranged on the top of the L-shaped mounting plate 11. The clamping cylinder 30 is connected to the movable plate 31. Two inclined grooves 34 are provided on the movable plate 31. Two sliding blocks 35 that slide together are provided on the slide 33. The slider 35 is provided with a sliding column 36 that slides together with the inclined groove 34. The two clamping ends 4 are respectively connected to the two sliders 35; the clamping end 4 includes a clamping plate 41 and a mounting plate 42. One end of the clamping plate 41 is horizontally connected to the slider 35, and the mounting plate 42 is connected to the other end of the clamping plate 41.

[0022] During the process of clamping the workpiece, the clamping cylinder 30 drives the movable plate 31 to move horizontally on the L-shaped mounting plate 42 through the two slideways 33, and then drives the two slide columns 36 to move on the slide rail 32 through the two inclined grooves 34 on the movable plate 31, and drives the two sliders 35 to move closer or farther away, thereby driving the position of the two clamping plates 41 to move and clamp the workpiece.

[0023] In this preferred embodiment, the clamping and flipping mechanism 5 includes a flipping motor 51, a first flipping disk 52 and a second flipping disk 53. The first flipping disk 52 and the second flipping disk 53 are respectively rotatably connected to two mounting plates 42. The flipping motor 51 is located on one of the mounting plates 42. The main shaft of the flipping motor 51 is transmission-connected to the first flipping disk 52.

[0024] After the workpiece is clamped, the workpiece is located between the first flip disk 52 and the second flip disk 53. The flip motor 51 then drives the first flip disk 52 to rotate on the mounting plate 42, thereby driving the second flip disk 53 to rotate on another mounting plate 42 through the workpiece. The position of the workpiece is flipped and rotated. During the processing of the workpiece, processing can be performed at any position of the workpiece, thereby ensuring the uniformity of processing of each surface of the workpiece, reducing the number and time of clamping, and realizing parallel processing of multiple processes.

[0025] In this preferred embodiment, the clamping mold 2 includes two clamping disks 20, each of which is provided with five plug-in rods 201, and the two clamping disks 20 are provided with five plug-in holes 54 that are plugged into the first flip disk 52 and the second flip disk 53. The first flip disk 52 and the second flip disk 53 are each provided with two locking screws 202, and the plug-in rod 201 is provided with a threaded hole that is threadedly connected to the locking screw 202, and the clamping disk 20 is provided with a clamping part 21.

[0026] When the two clamping discs 20 are respectively inserted into the first flip disc 52 and the second flip disc 53, the two clamping discs 20 can be respectively fixed in the first flip disc 52 and the second flip disc 53 by the corresponding two locking screws 202. When the clamping disc 20 needs to be replaced for clamping different types of workpieces, the two corresponding locking screws 202 are loosened to move the two clamping discs 20 from the first flip disc 52 and the second flip disc 53 respectively.

[0027] Example 1: In this preferred embodiment, the clamping member 21 includes a driving motor 211, a driving bidirectional screw rod 212 and a clamping block 213. The clamping disc 20 is provided with a first slide groove. The driving motor 211 is located in the first slide groove. The driving bidirectional screw rod 212 is transmission-connected to the main shaft of the driving motor 211. The driving bidirectional screw rod 212 is rotationally connected to the first slide groove. The two clamping blocks 213 are respectively threadedly connected to the driving bidirectional screw rod 212; the clamping rod 231 is provided with a plurality of threaded convex clamping heads 214.

[0028] When clamping a square workpiece, when encountering a large workpiece, the convex clamping heads 214 contact the workpiece, and then the mechanical clamping mechanism 3 works to clamp the left and right sides of the workpiece. The convex clamping heads 214 can increase the friction force, making the clamping effect better. When encountering a small workpiece, the two ends of the workpiece are placed between the two clamping blocks 213. After that, the driving motor 211 drives the bidirectional screw rod 212 to rotate, which can drive the positions of the two clamping blocks 213 to move inward to clamp and fix the workpiece; in the process of clamping the workpiece, square workpieces of different sizes can be clamped, thereby improving the adaptability of the device.

[0029] Example 2: In this preferred embodiment, the clamping member 21 includes a rotating motor 221, a rotating shaft 222, a rotating plate 223 and two clamping wheels 224. The rotating shaft 222 is located in the middle position of the rotating plate 223. A second slide groove is provided on the clamping disk 20. The rotating shaft 222 is rotatably connected to the middle position of the second slide groove. The rotating plate 223 is L-shaped. The rotating motor 221 is located in the clamping disk 20 and the rotating motor 221 is transmission-connected to the rotating shaft 222. The two clamping wheels 224 are respectively rotatably connected to the two ends of the rotating plate 223.

[0030] When clamping a special-shaped workpiece or a workpiece with an inclined surface, the rotating motor 221 drives the rotating shaft 222 to rotate, and the rotation of the rotating shaft 222 can drive the rotating plate 223 to rotate, so that the two clamping wheels 224 are in contact with the surface of the special-shaped workpiece or the workpiece with an inclined surface, thereby fixing the workpiece and preventing the position of the workpiece from shaking during the clamping process, thereby affecting the accuracy of subsequent workpiece processing.

[0031] Example 3: In this preferred embodiment, the clamping member 21 includes three clamping rods 231 arranged at equal intervals, and the ends of the clamping rods 231 are rounded.

[0032] When clamping an annular workpiece, the mechanical clamping mechanism 3 drives the two clamping plates 41 to move relative to each other, and the end faces 232 come into contact with the outer end faces of the workpiece to achieve clamping of the circular part. The outer circles of the three clamping rods 231 fit and embrace the outer surface of the circular workpiece to achieve positioning of the circular part.

[0033] In the process of clamping different types of workpieces, the present invention can select different types of clamping methods according to the clamping needs, so that the fit between the clamp and the workpiece is more precise, the workpiece is clamped more stably, and the applicability of the device is improved.

It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
