[0004] However, in the existing technology, two groups of clamping plates are used to clamp and fix the workpiece. When the shape of the workpiece is cylindrical and the diameter is large, the two groups of clamping plates can only clamp the lower sides of both sides of the cylindrical workpiece, resulting in the workpiece being easily separated from the upper part between the two groups of clamping plates, and the positioning and pushing effect is poor. Therefore, a positioning and pushing device for numerical control grinding machines is proposed. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] A positioning and pushing device for a numerical control grinding machine, as Figures 1 - 5 shown, includes a base 1. A pushing material driving part 2 is fixedly connected to the upper end of the base 1. The pushing material driving part 2 can be a driving device such as a pushing material cylinder. The output end of the pushing material driving part 2 is fixedly connected to a pushing material plate 3. The lower end of the pushing material plate 3 is slidably connected to the upper end of the base 1. A positioning assembly is slidably connected to the side of the pushing material plate 3 away from the pushing material driving part 2. When the lower end of the pushing material plate 3 slides on the upper end of the base 1, they will not separate. The output end of the pushing material driving part 2 and one side of the pushing material plate 3 are fixedly connected by bolts, and the pushing material plate 3 can be replaced. The positioning assembly clamps and positions the workpiece to prevent the workpiece from shifting during pushing.

[0026] A horizontal groove 5 is opened on one side of the pushing material plate 3. The positioning assembly includes two groups of clamping plates 8. A first slider 7 is fixedly connected to one side of each of the two groups of clamping plates 8. The two groups of first sliders 7 are both slidably connected in a chute 18, so that the two groups of clamping plates 8 will not rotate. A double-headed threaded rod 6 is rotatably connected in the horizontal groove 5. The thread directions at both ends of the double-headed threaded rod 6 are opposite. The two groups of first sliders 7 are respectively threadedly connected to both ends of the double-headed threaded rod 6. When the double-headed threaded rod 6 rotates, it will drive the two groups of clamping plates 8 to move in opposite directions, so that the two groups of clamping plates 8 clamp the workpiece. A pressing plate 12 is slidably connected to one side of the pushing material plate 3. The pressing plate 12 slides up and down on one side of the pushing material plate 3. The two groups of clamping plates 8 are symmetrically arranged relative to the vertical groove 4. Connecting plates 14 are clamped at both ends of the pressing plate 12. The angle between the connecting plate 14 and the clamping plate 8 can be adjusted. The upper ends of the two groups of clamping plates 8 are respectively slidably connected in the two groups of connecting plates 14. The angle between the connecting plate 14 and the clamping plate 8 is an obtuse angle. When the upper ends of the two groups of clamping plates 8 slide along the inclined connecting plates 14 at the same time, because the two groups of clamping plates 8 are symmetric relative to the pressing plate 12, the two groups of clamping plates 8 will pull the pressing plate 12 to slide.

[0027] When the double-headed threaded rod 6 drives the two groups of clamps 8 to clamp the workpiece close, the upper ends of the two groups of clamps 8 will slide on the two groups of connecting plates 14, pulling the pressure plate 12 to slide downward on the side wall of the pushing plate 3, squeezing the top of the workpiece to prevent the workpiece from escaping from between the two groups of clamps 8, and the positioning and pushing effect is better. When the double-headed threaded rod 6 drives the two groups of clamps 8 to move away, the upper ends of the two groups of clamps 8 move away and slide along the two groups of connecting plates 14, driving the pressure plate 12 to lift, thereby increasing the space between the two groups of clamps 8 and the pressure plate 12, which is convenient for unloading or loading.

[0028] The two groups of clamping plates 8 are symmetrically arranged, a vertical slot 4 is opened on one side of the push plate 3, a second slide block 11 is fixedly connected to one side of the pressure plate 12, and the second slide block 11 is slidably connected in the vertical slot 4.

[0029] like Figure 1 As shown, the two groups of clamping plates 8 are symmetrically arranged relative to the vertical groove 4 , the second sliding block 11 slides in the vertical groove 4 of the pushing plate 3 , and the lower end of the vertical groove 4 is connected to the middle of the horizontal groove 5 .

[0030] The upper ends of the two groups of clamping plates 8 are fixedly connected with connecting columns 9, the ends of the two groups of connecting columns 9 are fixedly connected with balls 10, and the two groups of connecting plates 14 are provided with sliding grooves 18, and the two groups of balls 10 are slidably connected in the two groups of sliding grooves 18 respectively.

[0031] like Figures 1 - 5 As shown, the shape of the slide groove 18 is set to be a "convex" shape, and the ball 10 slides inside the slide groove 18 and can change its angle as it slides. The ball 10 will not fall out of the slide groove 18. The splint 8 pulls or pushes the pressure plate 12 to slide through the ball 10, so that the pressure plate 12 moves and slides with the splint 8, and no additional driving equipment is required to drive the pressure plate 12 to slide.

[0032] The two ends of the pressure plate 12 are fixedly connected to a side away from the push plate 3 with a fixing plate 15, and the two sets of fixing plates 15 are both circular in shape. The side walls of the two sets of connecting plates 14 close to the pressure plate 12 are fixedly connected to a fixing arm 19, and the two sets of fixing arms 19 are respectively engaged with the two sets of fixing plates 15.

[0033] like Figures 1 - 5 As shown, one end of the two sets of connecting plates 14 can be rotatably connected at both ends of the pressure plate 12, and the angle between the connecting plate 14 and the pressure plate 12 can be adjusted so that when the two sets of clamps 8 clamp the workpiece, the pressure plate 12 can just squeeze the upper end of the workpiece. After the angle of the connecting plate 14 is adjusted, the fixed arm 19 is snap-fitted with the fixed plate 15 to fix the angle of the connecting plate 14.

[0034] The two sets of fixing plates 15 are both provided with connecting openings 17, one end of the two sets of fixing arms 19 are respectively rotatably connected to the two sets of connecting openings 17, and the other end is fixedly connected to elastic plug blocks 20. The two sets of fixing plates 15 are both provided with multiple sets of slots 16 arranged in a circular array, and the elastic plug blocks 20 are snap-fitted with the slots 16.

[0035] As Figures 1 - 5 shown, one end of the fixed arm 19 penetrates and is rotatably connected to the connection port 17. The fixed arm 19 is shaped like an "L". One end of the elastic insert block 20 penetrates the fixed arm 19. By pulling the elastic insert block 20, the elastic insert block 20 contracts inside the fixed arm 19. The fixed arm 19 and the connecting plate 14 can rotate and adjust the angle on the pressing plate 12. After the adjustment is completed, release the elastic insert block 20, and the elastic insert block 20 is clamped with the slot 16, and the fixed arm 19 cannot rotate. Therefore, the connecting plate 14 is clamped and fixed with the pressing plate 12.

[0036] A protective pad 21 is clamped at the connection of the horizontal groove 5 and the vertical groove 4. One side of the protective pad 21 is fixedly connected with a plurality of mounting blocks 22, and the plurality of mounting blocks 22 are respectively clamped in the horizontal groove 5 and the vertical groove 4.

[0037] As Figures 1 - 2 shown, the protective pad 21 prevents the workpiece from being damaged when the pusher plate 3 pushes the workpiece. The protective pad 21 does not affect the rotation of the double-headed threaded rod 6, and is installed on the vertical groove 4 and the horizontal groove 5 through the mounting blocks 22, which is convenient for the disassembly and assembly of the protective pad 21.

[0038] The working principle of a numerical control grinding machine positioning and pushing device provided by the present utility model is as follows:

[0039] The double-headed threaded rod 6 drives the two clamping plates 8 to clamp the workpiece closer. The two spheres 10 will slide in the sliding grooves 18 on the two connecting plates 14. Pull the pressing plate 12 to slide downward on the side wall of the pusher plate 3 to squeeze the upper part of the workpiece to prevent the workpiece from separating from between the two clamping plates 8, and the positioning and pushing effect is good.

[0040] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
