Description
Technical Field
[0001] This application relates to the field of wrench clamping technology, and in particular to a clamping device for milling adjustable wrenches. Background Technology
[0002] Milling is a crucial step in the wrench manufacturing process, especially for milling the ends and surfaces of the wrench. Milling precisely shapes the wrench to the correct form and dimensions, ensuring that all parts meet design requirements, thereby achieving stable mechanical properties and reliable performance.
[0003] However, in actual production, the milling of different parts of the wrench has different requirements for the clamping method. For example, when milling the surface of the wrench, a stable and large-area clamping method is required to ensure that the wrench remains in a fixed position during the processing and to avoid the decrease in surface processing accuracy due to vibration or displacement. When milling the end of the wrench, a clamping device that can flexibly adjust the angle and position is required to adapt to the complex processing requirements of the end.
[0004] However, some existing clamping designs are relatively simple and have limited functionality, failing to effectively clamp different parts of the wrench according to the specific machining requirements. When facing milling operations on different parts, different clamping equipment often needs to be changed, reducing production efficiency and increasing production costs.
[0005] To address the aforementioned problems, a clamping device for milling with an adjustable wrench is now designed. Utility Model Content
[0006] This application provides a clamping device for milling adjustable wrenches, which solves the problem in related technologies that some clamps cannot clamp different parts of the wrench according to the processing needs of the wrench, resulting in inconvenience in operation. In a first aspect, a clamping device for milling with an adjustable wrench is provided, comprising: A base on which a flat clamp and an end clamp are provided; The planar clamp includes a traveling unit mounted on a base and a planar clamping platform connected to the traveling unit. The traveling unit is used to drive the planar clamping platform to move along the length and / or width of the base, and the planar clamping platform is used to clamp both sides of the wrench. The end clamp includes a mounting base on the base, a pneumatic gripper at one end of the mounting base, and a rotating component on the other side of the mounting base. The rotating component is connected to the pneumatic gripper and is used to drive the pneumatic gripper to rotate. The pneumatic gripper is used to clamp one end of the wrench.
[0007] In some embodiments, the traveling unit includes an X-axis drive mounted on a base and a Y-axis drive mounted on the X-axis drive.

[0010] In some embodiments, the planar clamping platform includes a clamping platform disposed on a slide, the clamping platform having a receiving groove for placing a wrench, and the bottom of the receiving groove having multiple punches.

One end of the rotating shaft is connected to the pneumatic gripper, and the other end of the rotating shaft extends outside the mounting base. Both the rotating shaft and the output shaft of the drive motor are provided with a pulley. A second pulley is rotatably disposed on the mounting base. The adjacent pulleys are connected to each other via belt drive.
[0013] This application provides a clamping device for milling a movable wrench. The traveling unit can control the movement of the planar clamping table in the length and width directions, so that the position of the wrench on the plane can be precisely adjusted. When milling the surface of the wrench, it can ensure that the wrench is in the optimal processing position, reduce processing errors caused by position deviation, and thus improve the accuracy of surface milling.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0020] This application provides a clamping device for milling adjustable wrenches, which solves the problem in related technologies that some clamps cannot clamp different parts of the wrench according to the processing needs of the wrench, resulting in inconvenience in operation.
[0021] Please see Figures 1-3 A clamping device for milling with an adjustable wrench includes: a base 1 on which a flat clamp 2 and an end clamp 3 are disposed; The planar clamp 2 includes a traveling unit 21 mounted on a base 1 and a planar clamping platform 22 connected to the traveling unit 21. The traveling unit 21 is used to drive the planar clamping platform 22 to move along the length and / or width of the base 1. The planar clamping platform 22 is used to clamp both sides of the wrench. The end clamp 3 includes a mounting base 31 on the base 1, a pneumatic gripper 32 at one end of the mounting base 31, and a rotating component 33 on the other side of the mounting base 31. The rotating component 33 is connected to the pneumatic gripper 32 and is used to drive the pneumatic gripper 32 to rotate. The pneumatic gripper 32 is used to clamp one end of the wrench.
[0022] The planar clamp 22 is driven by the traveling unit 21 to move along the X and Y axes, which enables the planar clamp 22 to move flexibly in the length and width directions of the base, and effectively clamps the two sides of the wrench through the planar clamp 22.
[0023] When it is necessary to clamp one end of the wrench, the pneumatic gripper 32 clamps the wrench tightly, and the rotating component 33 drives the pneumatic gripper 32 to rotate together, thereby driving the clamped wrench to rotate to meet the processing requirements of different angles.
[0024] The travel unit 21 can control the movement of the planar clamp 22 in the length and width directions, so that the position of the wrench on the plane can be precisely adjusted. When milling the surface of the wrench, it can ensure that the wrench is in the optimal processing position, reduce the processing error caused by position deviation, and thus improve the accuracy of surface milling.
[0025] The pneumatic gripper 32 can stably hold one end of the wrench, and the rotating component 33 can drive the pneumatic gripper 32 to rotate, so that the end of the wrench can be processed at different angles. This provides a flexible processing method for end milling, which can better meet the processing requirements of complex end shapes and improve the accuracy of end processing.
[0026] The quick clamping and releasing function of the pneumatic gripper 32 and the rotation drive function of the rotating component 33 make the operation of the wrench end more convenient. During the processing, the angle of the wrench end can be adjusted at any time as needed without disassembling and reinstalling the wrench, which greatly shortens the processing time and improves production efficiency.
[0027] like Figure 1 and Figure 2 As shown, in one embodiment, the traveling unit 21 includes an X-axis drive member 211 disposed on the base 1, and a Y-axis drive member 212 disposed on the X-axis drive member 211. The length of the base 1 is taken as the X-axis, and the width of the base 1 is taken as the Y-axis.
[0028] The position of the planar clamp 22 in the X-axis direction is adjusted by the X-axis drive component 211, and the planar clamp 22 is adjusted to make linear motion in the width direction Y-axis direction by the Y-axis drive component 212. Through the coordinated work of the X-axis and Y-axis drive components, the two-dimensional precise movement of the planar clamp on the base plane can be realized.
[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the X-axis drive unit 211 further includes a fixed platform 211.1 disposed on the base 1, and two slide rails 211.2 are disposed opposite each other above the fixed platform 211.1, and a movable plate 211.3 is slidably disposed on the slide rails 211.2; Two bearing seats 211.4 are arranged opposite each other on one side of the fixed platform 211.1. A lead screw 211.5 is rotatably connected between the two bearing seats 211.4. One end of the lead screw 211.5 extends outward, and a handwheel 211.6 is provided at the outward-extending end of the lead screw 211.5. A moving block 211.7 is threadedly connected to the lead screw 211.5, and the top end of the moving block 211.7 is connected to the moving plate 211.3. The moving block 211.6 has a threaded hole that matches the lead screw 211.5.
[0030] When it is necessary to adjust the position of the plane clamp in the X-axis direction, turn the handwheel 211.6. The handwheel 211.6 drives the lead screw 211.5 to rotate between the two bearing seats 211.4. Since the moving block 211.7 has a threaded hole that matches the lead screw 211.5, when the lead screw 211.5 rotates, the moving block 211.6 will move linearly along the lead screw 211.5.
[0031] Since the top of the moving block 211.6 is connected to the moving plate 211.3, the moving plate 211.3 will slide on the two slide rails 211.2, thereby realizing the movement of the planar clamp 22 in the X-axis direction.
[0032] It should be noted that turning the handwheel 211.6 clockwise will move the moving block 211.6 and the moving plate 211.3 in one direction; turning the handwheel 211.6 counterclockwise will move them in the opposite direction.
[0033] like Figure 4 and Figure 5 As shown, furthermore, the movable plate 211.3 has a groove, and the Y-axis drive component 212 includes a lead screw 212.1 rotatably disposed within the groove. A movable block 212.2 is threadedly connected to the lead screw 212.1. A sliding plate 212.3 is slidably disposed above the movable plate 211.3, and the movable block 212.2 is connected to the sliding plate 212.3. A handwheel 212.4 is provided at one end of the lead screw 212.1. A threaded hole adapted to the lead screw 212.1 is provided on the movable block 212.2.
[0034] When it is necessary to adjust the position of the flat clamp in the Y-axis direction, the operator turns handwheel 212.4.
[0035] Handwheel 212.4 drives lead screw 212.1 to rotate in the groove of moving plate 211.3. Since moving block 212.2 has a threaded hole that matches lead screw 212.1, when lead screw 212.1 rotates, moving block 212.2 will move linearly along lead screw 212.1, and slide plate 212.3 will slide above moving plate 211.3, thereby driving the planar clamp to move in the Y-axis direction.
[0036] It should be noted that turning handwheel 212.4 clockwise will move moving block 212.2 and slide plate 212.3 in one direction; turning handwheel 212.4 counterclockwise will move them in the opposite direction.
[0037] like Figure 2 and Figure 3As shown, in one embodiment, the planar clamping platform 22 includes a clamping platform 221 disposed on the slide plate 212.3. The clamping platform 221 has a receiving groove 222 for placing a wrench. The bottom of the receiving groove 222 has a plurality of punch holes 223.
[0038] The clamping platform 221 on the slide plate 212.3 serves as the main support. The movement of the slide plate 212.3 can drive the clamping platform 221 to adjust its position in the X and Y axis directions, providing a flexible position adjustment function for the workpiece placed on it to meet the needs of different processing positions.
[0039] The receiving groove 222 is used to hold the wrench, and the multiple punches 223 have multiple functions. On the one hand, cutting fluid, chips and other materials generated during the processing can be discharged through the punches to prevent them from accumulating in the receiving groove, keeping the receiving groove clean and reducing contamination and damage to tools such as wrenches. On the other hand, the punches 223 can also be used to cooperate with milling cutters and drill bits.
[0040] like Figure 3 As shown, the planar clamping platform 22 further includes a clamping piece 224 disposed on one side of the receiving groove 222, and a movable clamping piece 225 attached to the other side of the receiving groove 222. A threaded cylinder 226 is embedded inside the clamping platform 221. A lead screw 227 is threadedly connected inside the threaded cylinder 226. One end of the lead screw 227 is connected to the movable clamping piece 225, and a handwheel 228 is provided at the other end of the lead screw 227.
[0041] The clamping platform 221 has a through hole for the threaded cylinder 226, and the internal thread of the threaded cylinder 226 is compatible with the lead screw 227.
[0042] Two sliding holes are formed opposite to each other on the clamping platform 221. A guide rod is inserted into the sliding hole, and one end of the guide rod is connected to the movable clamping piece 225.
[0043] When it is necessary to clamp and fix the wrench placed in the receiving groove 222, turn the handwheel 3 228. The handwheel 3 228 drives the lead screw 3 227 to rotate inside the threaded cylinder 226. Since the threaded cylinder 226 is fixedly embedded inside the clamping platform 221, the lead screw 3 227 will move linearly along its axis during rotation.
[0044] One end of the lead screw is connected to the movable clamp 225, which pushes the movable clamp 225 toward the clamp 224 fixed on one side of the receiving groove 222, thereby clamping the wrench between the two.
[0045] The two sliding holes on the clamping platform 221 and the guide rod inserted therein play an important guiding and stabilizing role. During the movement of the moving clamp 225, the guide rod slides in the sliding hole to ensure that the moving clamp 225 can only move in a straight line and will not deflect or shake, thereby ensuring the accuracy and stability of clamping.
[0046] It should be noted that handwheel 1 (211.6), handwheel 2 (212.4), and handwheel 3 (228) are all equipped with rotation angle scales.
[0047] like Figure 2 and Figure 5 As shown, in one embodiment, the mounting base 31 and the traveling unit 21 are arranged opposite to each other on the base 1; The rotating component 33 includes a drive motor 331 disposed on one side of the mounting base 31. A rotating shaft 332 is rotatably disposed inside the mounting base 31. One end of the rotating shaft 332 is connected to the pneumatic gripper 32, and the other end of the rotating shaft 332 extends outside the mounting base 31. Both the output shaft of the rotating shaft 332 and the drive motor 331 are provided with a pulley 333. A second pulley 334 is rotatably disposed on the mounting base 31. The adjacent pulleys 334 and pulley 333 are connected by belt drive.
[0048] After the drive motor 331 starts, its output shaft drives the pulley 333 connected to it to rotate. Since the pulley 333 is connected to the pulley 334 on the mounting base 31 via a belt, the pulley 334 will rotate synchronously with the pulley 333. Then, the pulley 334 is connected to the pulley 333 on the rotating shaft 332 via another belt, thereby driving the rotating shaft 332 to rotate.
[0049] One end of the rotating shaft 332 is connected to the pneumatic gripper 32, which ultimately realizes the rotation of the pneumatic gripper 32. This multi-stage belt drive method smoothly and effectively transmits the power of the drive motor to the pneumatic gripper.
[0050] Mounting base 31 and traveling unit 21 are arranged opposite each other on base 1, making the relative positions of each component clear and facilitating installation and maintenance.
[0051] The drive motor 331 of the rotating component 33 is located on one side of the mounting base 31, which does not take up too much space. It is also compact in layout with the rotating shaft 332, pulley and other components, and the overall structure is relatively regular.
