[0002] Clamping positioning is the most common positioning method in vertical machining. It installs a clamp on the workpiece and clamps the workpiece on the machining platform to ensure machining accuracy and stability. Clamps are generally divided into two types: mechanical clamps and hydraulic clamps. Mechanical clamps are suitable for clamping small and medium-sized workpieces, while hydraulic clamps are suitable for clamping large workpieces. In the selection and use of clamps, it is necessary to select the appropriate clamp type and clamping scheme according to the characteristics of the workpiece and the machining requirements to ensure machining quality and production efficiency.
[0003] The existing clamping and positioning device drives the clamp by mechanical or hydraulic means, so that the clamp clamps the workpiece at the center of the placement plate for processing. The clamping of the workpiece can prevent the workpiece from shifting due to vibration generated during processing.
[0004] However, when the existing clamping and positioning device clamps the workpiece, the two clamping plates may be inaccurately positioned during the clamping and positioning of the workpiece because the workpiece is generally a hard solid and has different shapes, resulting in an insignificant clamping effect, and the workpiece will deviate during processing. Utility Model Content

[0011] Beneficial Effects
[0012] The utility model provides a clamping and positioning device for a high-speed vertical machining center. It has the following beneficial effects: the clamping and positioning device for a high-speed vertical machining center cooperates with a cylinder, a rotating wheel and a V-shaped positioning groove. When a workpiece needs to be processed, the workpiece is first placed on the top of a movable plate, and the cylinder is started. The cylinder drives the first clamping plate to move in the direction of the second clamping plate, and the workpiece can be pushed toward the second clamping plate.

[0013] Through the cooperation between the servo motor, the screw and the positioning rod, when different positions of a workpiece need to be processed, the servo motor is started, and the servo motor drives the screw to rotate. Since the movable plate and the screw are in a threaded connection relationship, the rotation of the screw can realize the left and right translation of the movable plate.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] When the existing clamping and positioning device clamps the workpiece, the two clamping plates may be inaccurately positioned during the clamping and positioning of the workpiece because the workpiece is generally a hard solid and has different shapes, resulting in an insignificant clamping effect, and the workpiece may deviate during processing.
[0023] In view of this, the utility model provides a high-speed vertical machining center and a clamping device. Through the cooperation between the cylinder, the rotating wheel and the V-shaped positioning groove, when the workpiece needs to be processed, the workpiece is first placed on the top of the movable plate, and the cylinder is started. The cylinder drives the first clamping plate to move in the direction of the second clamping plate, and the workpiece can be pushed toward the second clamping plate. Before the first clamping plate and the second clamping plate are about to be clamped, the workpiece will first collide with the rotating wheel above the two clamping plates, and the workpiece can be straightened by the rotation of the rotating wheel. Finally, the two ends of the workpiece are just clamped by the two V-shaped positioning grooves, thereby achieving a more stable positioning and clamping of the workpiece.
[0024] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.
[0025] Embodiment 1: By Figure 1-4 It can be seen that a high-speed vertical machining center clamping and positioning device includes a body 1, a first electric slide rail 10 is fixedly connected to the top of the body 1, an electric slide plate 11 is slidably clamped on the top of the first electric slide rail 10, a moving plate 13 is arranged on the top of the electric slide plate 11, and a positioning clamping device is arranged on the top of the moving plate 13. The positioning clamping device includes a cylinder 8, a first clamping plate 9, a rotating wheel 14, a V-shaped positioning groove 16 and a second clamping plate 17. The cylinder 8 is fixedly connected to the top of the moving plate 13, the output end of the cylinder 8 is fixedly connected to the first clamping plate 9, and the bottom of the first clamping plate 9 is movably connected to The second clamping plate 17 is arranged on the top of the movable plate 13 and the side of the first clamping plate 9 away from the cylinder 8. The second clamping plate 17 is fixedly connected to the top of the movable plate 13 by bolts. The position of the second clamping plate 17 can be moved according to the size of the workpiece to perform more effective clamping work. The second clamping plate 17 is fixedly connected to the top of the movable plate 13 by bolts. The tops of the first clamping plate 9 and the second clamping plate 17 are both rotatably connected with a rotating wheel 14. The first clamping plate 9 and the second clamping plate 17 are both provided with a V-shaped positioning groove 16 on the opposite side. The models of the first electric slide rail 10 and the electric slide plate 11 are not described in detail here.
[0026] In the specific implementation process, it is worth pointing out that when the workpiece needs to be processed, the workpiece is first placed on the top of the movable plate 13, and the cylinder 8 is started. The cylinder 8 drives the first clamping plate 9 to move in the direction of the second clamping plate 17, and the workpiece can be pushed toward the second clamping plate 17. Before the first clamping plate 9 and the second clamping plate 17 are about to be clamped, the workpiece will first collide with the rotating wheel 14 above the two clamping plates, and the workpiece can be straightened by the rotation of the rotating wheel 14. Finally, the two ends of the workpiece are just clamped by the two V-shaped positioning grooves 16, so that the workpiece is more firmly positioned and clamped.
[0027] Furthermore, a servo motor 7 is fixedly connected to the top of the electric skateboard 11, a screw 6 is fixedly connected to the output end of the servo motor 7, the outer wall of the screw 6 is threadedly connected to the inner wall of the moving plate 13, a limit rod 12 is inserted into the inner wall of the moving plate 13, and the end of the limit rod 12 is fixedly connected to the top of the electric skateboard 11;
[0028] In the specific implementation process, it is worth pointing out that when different positions of a workpiece need to be processed, the servo motor 7 is started, and the servo motor 7 drives the screw 6 to rotate. Since the movable plate 13 and the screw 6 are in a threaded connection relationship, the rotation of the screw 6 can realize the translation of the movable plate 13 to the left and right, and the two limit rods 12 on the inner wall of the movable plate 13 can prevent the movable plate 13 from being unstable during translation;
[0029] Specifically, when using the clamping and positioning device of the high-speed vertical machining center, when the workpiece needs to be processed, the workpiece is first placed on the top of the movable plate 13, and the cylinder 8 is started. The cylinder 8 drives the first clamping plate 9 to move in the direction of the second clamping plate 17, and the workpiece can be pushed toward the second clamping plate 17. Before the first clamping plate 9 and the second clamping plate 17 are about to be clamped, the workpiece will first collide with the rotating wheel 14 above the two clamping plates, and the workpiece can be straightened by the rotation of the rotating wheel 14. Finally, the two ends of the workpiece are clamped by the two V-shaped positioning grooves 16. When different positions of a workpiece need to be processed, the servo motor 7 is started, and the servo motor 7 drives the screw 6 to rotate. Because the movable plate 13 and the screw 6 are in a threaded connection relationship, the rotation of the screw 6 can realize the left and right translation of the movable plate 13, and the two limit rods 12 on the inner wall of the movable plate 13 can prevent the movable plate 13 from being unstable during translation.

[0031] In the specific implementation process, it is worth pointing out that vertical processing can realize more detailed and precise processing of the workpiece, and the tool 15 needs to be moved up and down in real time. The outer wall of the electric slide block 2 is slidably connected to the inner wall of the second electric slide rail 19, which can drive the lifting box 5 to move up and down, and the height of the tool 15 can be adjusted;
[0032] Furthermore, the top of the lifting box 5 is fixedly connected with the housing 3 by bolts, and a high-speed motor 4 is installed inside the housing 3;
[0033] In the specific implementation process, it is worth pointing out that the model of the high-speed motor 4 is 3542-1.1-12000, and the output end can rotate at a high speed, so that the workpiece can be processed more efficiently;
[0034] Furthermore, the output end of the high-speed motor 4 passes through the lifting box 5 and is fixedly connected with a threaded barrel 18, the inner wall of the threaded barrel 18 is threadedly connected with a cutter 15, and the bottom of the cutter 15 passes through a circular hole opened at the bottom of the lifting box 5;
[0035] In the specific implementation process, it is worth pointing out that due to different requirements for workpiece processing, the selection of the tool 15 may also be different. Since the tool 15 and the threaded barrel 18 are in a threaded connection relationship, the tool 15 can be replaced before processing to achieve the effect of meeting the processing requirements;
[0036] Specifically, on the basis of the above-mentioned embodiment 1, when the tool 15 needs to be moved up and down in real time, the outer wall of the electric slider 2 is slidably engaged with the inner wall of the second electric slide rail 19, which can drive the lifting box 5 to move up and down, and the height of the tool 15 can be adjusted. Since the tool 15 and the threaded barrel 18 are in a threaded connection relationship, the tool 15 can be replaced before processing, and the output end of the high-speed motor 4 can rotate at high speed, so that the workpiece can be processed more efficiently.
