Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] As shown in Figures 1-4 A adjustable tooling of numerical control center, including empty slot 1, empty slot 1 is set up in numerical control machining center workbench top, the inside both sides wall of empty slot 1 is rotatably connected with screw rod 2, one end of screw rod 2 is drivingly connected with drive device 3, the surface of screw rod 2 is threadedly sleeved with sleeve 4, the inside both sides wall of empty slot 1 is also fixedly provided with limiting rod 5, and screw rod 2 and limiting rod 5 are arranged in parallel and spaced apart, the surface of limiting rod 5 is slidingly connected with limiting sleeve 6, sleeve 4 and limiting sleeve 6 are fixedly connected with the same supporting plate 7, and the upper surface of supporting plate 7 is provided with clamping mechanism 8 for clamping workpiece.

[0030] In this way, first, the drive device 3 drives the screw rod 2 to rotate, and the screw rod 2 is threadedly sleeved with the sleeve 4, and the limiting rod 5 and the limiting sleeve 6 guide and limit the supporting plate 7, so that the position of the supporting plate 7 in the horizontal direction can be adjusted conveniently, that is, the position of the supporting plate 7 can be adjusted according to the requirements of the workpiece, so that when the workpiece is placed and removed, the position of the tooling can be adjusted to allow the worker to operate in a safe area away from the machining head, avoiding the dangerous contact of traditional tooling, reducing the risk of injury caused by accidental touch, ensuring personal safety, and creating a safe working environment. The adjustable supporting plate 7 can accurately position the workpiece to the preset machining coordinate position, avoiding the initial placement deviation caused by the machining size error, and the clamping mechanism 8 can stably fix the workpiece, so that it does not displace or shake when subjected to external force, ensuring the accuracy and improving the product yield.

[0031] Secondly, the clamping mechanism 8 can operate more accurately according to the set force and angle when clamping the workpiece to be processed, so as to ensure that the workpiece is fixed firmly in the correct position and posture, thereby avoiding displacement of the workpiece during milling, drilling and other machining processes in the numerical control machining center, and helping to improve the machining quality and reduce the waste rate.

[0032] Thirdly, the tooling has the functions of adjustment and effective clamping, and is suitable for workpieces of various specifications and shapes, so that small precision parts or large block workpieces can be machined as long as they are within the adjustment and clamping range, thereby reducing the cost of enterprises to equip various special toolings and improving the universality and utilization rate of the tooling.

[0033] In the embodiment, the driving device 3 is a driving motor, and the driving motor is an MDS-E / EH series motor produced by Mitsubishi Electric.

[0034] The clamping mechanism 8 comprises a placing box 81, and the placing box 81 has a hollow structure, and two clamping plates 82 are arranged in parallel and opposite to the upper portion of the placing box 81.

[0035] Two slide rods 84 are fixedly arranged in parallel and at intervals in the placing box 81, and the axial direction of the slide rod 84 is consistent with the moving direction of the clamping plate 82, two slide sleeves 85 are slidably sleeved on the outer surface of the slide rod 84, and the four slide sleeves 85 are arranged in symmetry.

[0036] Two movable grooves 83 are symmetrically and through arranged on the two side walls of the placing box 81, the length direction of the movable groove 83 is consistent with the moving direction of the clamping plate 82, and two L-shaped transmission rods 87 are slidably arranged in the movable groove 83, and the two ends of the L-shaped transmission rod 87 are fixedly connected with the corresponding slide sleeve 85 and clamping plate 82 respectively.

[0037] The connecting plates 86 are arranged in the placing box 81 and below the clamping plates 82 respectively, the two ends of the connecting plate 86 are fixedly connected with the corresponding slide sleeve 85 respectively, and the clamping driving assembly 9 for driving the two clamping plates 82 to move close to or away from each other is arranged in the placing box 81 and between the two connecting plates 86.

[0038] In this way, first, the slide rod 84 is fixed between the two side walls in the placing box 81, the slide sleeve 85 is tightly sleeved on the slide rod 84 and can slide smoothly, and the slide sleeve 85 is connected with the clamping plate 82 and the connecting plate 86, so that the whole structure has high integrity, and it is not easy for the parts to be loose, misaligned and the like during long-term use, which can ensure that the clamping mechanism 8 operates stably and reliably, and provides a structural basis for stable clamping of the workpiece.

[0039] Secondly, by the axis direction of the sliding rod 84 and the length direction of the movable slot 83 are parallel to each other, the sliding sleeve 85 slides along the sliding rod 84, and the movement of the clamping plate 82 is limited and guided by the movable slot 83, so that the movement trajectory of the clamping plate 82 is very accurate and straight when the clamping plates 82 move close to or away from each other, thereby the workpiece can be clamped accurately in the set direction, avoiding the problems of inaccurate clamping position and uneven clamping force caused by the deviation of the movement direction of the clamping plate 82, which helps to improve the accuracy of workpiece clamping and ensure the processing quality.

[0040] Thirdly, the four sliding sleeves 85 are symmetrically arranged and can slide on the sliding rod 84, so that the distance between the two clamping plates 82 can be flexibly adjusted according to the width size of different workpieces, realizing effective clamping of the workpiece, enhancing the adaptability of the clamping mechanism 8 to workpieces of different sizes, and expanding the application range thereof.

[0041] Fourthly, by applying driving force between the two connecting plates 86 by the clamping driving assembly 9, the sliding sleeve 85, the clamping plate 82 and other components can be driven to move cooperatively by the connecting plate 86, thereby completing the clamping and loosening operation, so that the operator only needs to control the clamping driving assembly 9 to easily realize the opening and closing action of the clamping plate 82, and the operation process is simple and convenient, without complex auxiliary operation or additional adjustment steps, thereby improving the work efficiency.

[0042] Fifthly, when the clamping driving assembly 9 drives the clamping plate 82 to clamp the workpiece, the force is uniformly transmitted to each sliding sleeve 85 through the connecting plate 86, and then transmitted to the clamping plate 82 through the L-shaped transmission rod 87, so that the clamping force applied by the clamping plate 82 to both sides of the workpiece can be distributed more uniformly, avoiding the problems of local deformation of the workpiece or unstable clamping caused by excessive force on a single point, ensuring that the workpiece can stably withstand external forces such as cutting force during the machining process, and ensuring the smooth progress of the machining.

[0043] Sixthly, the components are cleverly arranged inside the placement box 81, which not only fully utilizes the internal space of the placement box 81, but also makes the whole clamping mechanism 8 compact and orderly, without occupying too much external space, which is conducive to reasonable layout on the limited workbench of the numerical control machining center, and is also convenient for cooperation with other tooling and equipment, thereby improving the overall space utilization efficiency.

[0044] The clamping driving assembly 9 comprises a vertical plate 91, which is fixedly installed on the inner wall of the bottom of the placement box 81, and the vertical plate 91 is located at the middle position between the two clamping plates 82.

[0045] The upper surface of the vertical plate 91 is rotationally connected with a rotating plate 92, both ends of the rotating plate 92 are respectively rotationally connected with two connecting rods 93, and the other ends of the connecting rods 93 are respectively rotationally connected with the corresponding connecting plates 86.

[0046] The electric push rod 94 is fixedly connected between the vertical plate 91 and one of the connecting plates 86.

[0047] In this way, first, the pushing force generated by the extension and retraction of the electric push rod 94 is transmitted to the driving assembly, and the rotating plate 92 and the connecting rod 93 cooperate to convert the linear motion into balanced pushing and pulling of the two connecting plates 86. By using the principle of leverage or amplifying the pushing force, the small-power electric push rod 94 can firmly hold the workpiece, reduce the power requirement of the driving component, save cost and improve efficiency.

[0048] Second, the pushing force generated by the extension and retraction of the electric push rod 94 is transmitted to the driving assembly, and the rotating plate 92 and the connecting rod 93 cooperate to convert the linear motion into balanced pushing and pulling of the two connecting plates 86. By using the principle of leverage or amplifying the pushing force, the small-power electric push rod 94 can firmly hold the workpiece, reduce the power requirement of the driving component, save cost and improve efficiency.

[0049] Third, the rotating plate 92 is rotatably connected to the two connecting plates 86 at both ends, and when the electric push rod 94 pushes or pulls one of the connecting plates 86, it drives the rotating plate 92 to rotate, and the force is evenly transmitted to the other connecting plate 86 through the connecting rod 93, ensuring that the two clamping plates 82 move in coordination and avoiding problems such as workpiece clamping skewing, uneven force, etc., ensuring stable and accurate clamping.

[0050] Fourth, the extension and retraction length of the electric push rod 94 can be accurately adjusted by controlling the power-on time and current size, and the distance between the clamping plates 82 can be accurately controlled to adapt to different widths of workpieces. Whether it is a small or large workpiece, it can be firmly clamped, improving the adaptation ability to different specifications of workpieces.

[0051] Fifth, the electric push rod 94 is easy to control electrically and can be easily connected to the automatic control system of the numerical control machining center. According to the preset program instructions, the clamping plate 82 can be automatically opened and closed, without the need for frequent manual adjustment, improving the automation level of the machining process and work efficiency, and meeting the development trend of numerical control machining.

[0052] In this embodiment, the electric push rod 94 is produced by Tianyuzhixi Technology.

[0053] The corrugated plate 10 is arranged above the hollow groove 1, and the fixed plate 11 is fixedly arranged at a position close to the hollow groove 1 on the top of the workbench of the numerical control machining center. The two ends of the corrugated plate 10 are fixedly connected with the support plate 7 and the fixed plate 11 respectively.

[0054] In this way, the corrugated plate 10 is arranged above the hollow groove 1, and the two ends thereof are fixedly connected with the support plate 7 and the fixed plate 11 respectively. The corrugated plate 10 can play a protective role, preventing debris and cooling liquid generated during machining from falling into the hollow groove 1 and affecting the normal operation of components such as the screw rod 2 and the limiting rod 5. At the same time, the corrugated plate 10 can also play a certain dustproof role on the internal structure, prolonging the service life of the tooling.

[0055] The surface of each of the two clamping plates 82 is fixedly adhered with a rubber pad, and the surface of each rubber pad is provided with anti-skid lines.

[0056] In this way, first, when the clamping plates 82 clamp the workpiece, the rubber pads are located at the positions directly contacted by the two clamping plates 82. Because the rubber pads are soft, compared with the hard surface of the clamping plates 82, the rubber pads can prevent the workpiece from being damaged, such as being scratched or indented, when clamped, which is particularly important for a workpiece with high surface precision, soft material or a processed workpiece, and is conducive to protecting the appearance quality of the workpiece and subsequent processing.

[0057] Second, the rubber pads have elasticity and a certain friction coefficient, and the anti-skid lines increase the roughness of the surface, so that the friction between the clamping plates 82 and the workpiece is greatly increased. When external force is encountered during processing, the greater friction can prevent the workpiece from sliding and displacing, stably fix the workpiece, and protect the processing precision and process safety.

[0058] Third, the elasticity of the rubber pads enables them to conform to the contour of workpieces of different shapes. For irregular workpieces, the clamping plates 82 can deform according to the shape of the workpieces when clamped, fill the gaps, achieve more comprehensive and uniform contact, strengthen the clamping effect, and expand the application range of the clamping mechanism 8.

[0059] Fourth, when impact force is generated during processing, especially cutting processing, the rubber pads can act as a buffer and shock absorber, absorb part of the impact force, reduce the transmission of the impact force to the workpiece and the tooling structure, avoid the workpiece from loosening and the parts from being damaged, prolong the service life of the tooling, and maintain the stable state of the workpiece.

[0060] When it is necessary to adjust the position of the tooling on the workbench of the numerical control machining center to adapt to the placement of the workpiece to be processed, first, the driving motor is started, the driving motor drives the screw rod 2 to rotate, the screw sleeve 4 moves linearly along the screw rod 2 in the axial direction, and the limiting sleeve 6 connected with the screw sleeve 4 slides along the limiting rod 5. The two cooperate to guide and support the support plate 7 to stably and accurately adjust the position in the horizontal direction. By controlling the forward rotation and reverse rotation of the motor and the rotation time, the support plate 7 is moved to the appropriate position to prepare for the placement of the workpiece to be processed.

[0061] Before clamping the workpiece, the electric push rod 94 is in the initial extension state, and through the connection relationship of the vertical plate 91 and the rotating plate 92 and other components, the two clamping plates 82 are in the initial position apart from each other, which is convenient for placing the workpiece to be processed.

[0062] The workpiece to be processed is placed between the two clamping plates 82 on the top of the placement box 81, the electric push rod 94 is started, the push rod is retracted to drive the connected connecting plate 86 to move, the two connecting plates 86 are synchronously driven to slide the sliding sleeve 85 along the sliding rod 84 through the action of the rotating plate 92 and the connecting rod 93, the sliding sleeve 85 drives the clamping plates 82 to move towards each other along the direction of the movable groove 83, until the rubber pads on the clamping plates 82 are in close contact with the two sides of the workpiece, and the workpiece is firmly fixed by relying on the characteristics of the rubber pads and the clamping force of the clamping plates 82, so as to prevent the workpiece from displacing and shaking during processing and to protect the processing precision.

[0063] After the numerical control machining is completed, the driving motor is started, the driving motor drives the screw rod 2 to rotate reversely, thereby driving the screw sleeve 4 and the supporting plate 7 to move, the placing box 81 and the workpiece are moved out from below the machining head, when the placing box 81 and the workpiece are moved to a safe position, the electric push rod 94 is started, the electric push rod 94 is elongated in the opposite direction, the force transmission and component movement process are opposite to the previous process, the two clamping plates 82 are away from each other, the workpiece is loosened, and the machined workpiece can be taken out.

[0064] For those skilled in the art, according to the teaching of the present application, the changes, modifications, replacements and variations made to the embodiments without departing from the principles and spirits of the present application still fall within the protection scope of the present application.
