Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a metal processing tooling with precise adjustment. Background Art

[0002] Metal processing, abbreviated as metalworking, refers to the production activities of humans processing materials with metallic properties composed of metal elements or mainly composed of metal elements. It is a process technology that processes metal materials into articles, parts, and components. Most of the tooling fixtures widely used in the current metal processing industry rely on manual adjustment and are difficult to meet the high-precision processing requirements. Traditional tooling fixtures often have deficiencies in adjustment accuracy and flexibility, resulting in large processing errors and affecting the quality of products.

[0003] The patent with the patent publication number CN213081209U discloses a high-efficiency fixture for metal product processing with rapid positioning. On both sides of the top of the bottom plate, a limiting plate is fixedly connected. On the opposite sides of the two limiting plates, a fixing plate is fixedly connected. On the front surface of the rear limiting plate, a bearing seat is fixedly connected. Inside the bearing seat, a bidirectional threaded rod is rotatably connected. The thread patterns on both sides of the surface of the bidirectional threaded rod are opposite. On both sides of the surface of the bidirectional threaded rod, a threaded sleeve is threadedly connected. On the top of the threaded sleeve, a clamping plate is fixedly connected. The top of the clamping plate penetrates through the top of the fixing plate and is movably connected with a connecting plate. At the bottom of the connecting plate, a fixing block is arranged. On the top of the connecting plate, a fixing groove is opened. The fixing block is adapted to the fixing groove. On both sides of the top of the fixing plate, a limiting groove is opened. The number of the limiting grooves is four. On the bottom of the clamping plate, a groove adapted to the limiting groove is opened.

[0004] The above-mentioned patented high-efficiency fixture for metal product processing with rapid positioning drives the bidirectional threaded rod through a motor, and then drives the clamping plate through the threaded sleeve to quickly position the workpiece. However, this fixture is only suitable for clamping metal workpieces with specific shapes. For metal parts with irregular shapes or special geometric structures, the clamping may not be stable enough, or even may not be able to clamp. In addition, when clamping thin-walled parts, deformation and other problems are likely to occur during the processing. Therefore, we have designed a metal processing tooling with precise adjustment to achieve the effect of accurately clamping and positioning metal workpieces with different shapes. Summary of the Utility Model

[0005] In order to overcome the shortcoming that the existing metal processing tooling cannot perform precise clamping adjustment on irregular workpieces when clamping workpieces, a metal processing tooling with precise adjustment is provided.

[0024] Embodiment: A precision-adjustable metal processing tooling, as Figure 1 and Figure 2 shown, includes a fixed frame 1, a fixed block I 2, a sliding rod I 3, a convex block 31, a return spring I 4, a sliding plate I 5, a fixed block II 6, a pull rod 61, a link rod 7, a return spring II 8 and a sliding plate II 9. The fixed frame 1 is the main body of this tooling. The front side of the fixed frame 1 is a cavity and there is an opening in the middle thereof. A plurality of fixed blocks I 2 are symmetrically fixedly connected inside the cavities on the front and rear sides of the fixed frame 1. A plurality of sliding rods I 3 are slidably installed on each of the fixed blocks I 2. Slide openings consistent with the number of the sliding rods I 3 are formed on the inner wall of the cavity on the front side of the fixed frame 1. The ends of the sliding rods I 3 are fixedly connected with convex blocks 31, and the convex blocks 31 extend upward to the top surface of the fixed frame 1. A return spring I 4 is arranged between the fixed block I 2 and the convex block 31. A sliding plate I 5 is symmetrically slidably installed in the middle opening of the fixed frame 1. Fixed blocks II 6 are symmetrically fixedly connected to the left and right side walls of the fixed frame 1. A pull rod 61 is slidably installed between the same-side fixed blocks II 6. The pull rod 61 is a U-shaped rod, and both ends of the pull rod 61 are hinged with link rods 7. A return spring II 8 is arranged between the fixed block II 6 and the pull rod 61. Sliding plates II 9 are symmetrically slidably installed on the front and rear sides of the top surface of the fixed frame 1. The sliding plates II 9 are in contact with the convex blocks 31. The sliding plates II 9 and the pull rod 61 are connected by the link rods 7, and the ends of the link rods 7 are slidably embedded inside the sliding plates II 9. A curved arc rod is arranged on the outer side of each sliding plate I 5, and the curved arc rod facilitates manual pushing and pulling of the sliding plate I 5 on the fixed frame 1 for movement.

[0025] As Figure 2 and Figure 3 shown, it further includes a limiting wedge block 81. The limiting wedge block 81 is fixedly connected to the right side of the fixed frame 1. The end surface of the upper part of the limiting wedge block 81 away from the fixed frame 1 is an inclined surface. The inclined surface of the limiting wedge block 81 is in contact with the pull rod 61, and the limiting wedge block 81 is used to limit the pulled-out pull rod 61. The sliding rods I 3 are all detachably installed on the fixed blocks I 2, and rubber pads for buffering are arranged at the ends of the sliding rods I 3, and the rubber pads can buffer the pressure of the sliding rods I 3 for clamping the workpiece.

[0026] AsFigure 3 and Figure 4 As shown in Figure 4 , it further includes a support plate 10 and a support rod 11. The bottom of the fixed frame 1 is symmetrically provided with support plates 10. Support rods 11 are slidably mounted on the support plates 10. The support plates 10 are slidably connected to the fixed frame 1 through the support rods 11. It further includes a fixed block III 12, a cam 13 and a knob 14. Fixed blocks III 12 are fixedly connected to the middle of the support plates 10. Cams 13 are installed on the fixed blocks III 12 through rotating shafts. The other ends of the rotating shafts are all installed with knobs 14. A circle of sockets is circumferentially formed inside the knob 14. A plurality of friction-increasing small blocks are provided on the curved surface of the knob 14. Through the small blocks, the user can conveniently turn the knob 14.

[0027] As Figure 5 shown in Figure 5 , it further includes a fixed block IV 15 and a sliding rod II 16. Fixed blocks IV 15 are fixedly connected to the support plates 10. Sliding rods II 16 are slidably mounted on the fixed blocks IV 15. The sliding rods II 16 are in a hook-shaped structure. The ends of the sliding rods II 16 are inserted into the sockets of the knobs 14.

[0028] When using this tooling, the operator first places the metal workpiece to be processed onto the sliding plate I 5. When the metal workpiece is placed at the appropriate processing position, the operator simultaneously pulls the pull rod 61. Under the guiding action of the fixed block II 6, the pulled pull rod 61 slides away from the fixed frame 1 against the elastic force of the return spring II 8. At this time, the sliding pull rod 61 simultaneously pulls the connecting rods 7 at both of its ends. Under the action of the connecting rods 7, the sliding plates II 9 on both the front and rear sides slide inward in opposite directions. The inward-sliding sliding plates II 9 will no longer restrict the convex blocks 31. The convex blocks 31 that have lost the restriction slide inward into the fixed frame 1 under the elastic force of the return spring I 4 until the sliding rods I 3 at different positions all press against and restrict the sides of the placed metal workpiece. At this time, the sliding rods I 3 can stably limit and clamp metal workpieces of various shapes under the action of the return spring I 4. When the metal workpiece is stably clamped, by sliding the limit wedge 81 upward, the plane of the limit wedge 81 is restricted on the pulled pull rod 61, making the pull rod 61 unable to be pulled back by the return spring II 8. And when the metal workpiece is stably clamped, by pulling the sliding plate I 5 outward, the bottom of the metal workpiece can be exposed, facilitating processing the metal workpiece from the bottom. When it is necessary to adjust the processing height of the metal workpiece, the operator pulls the sliding rod II 16. After the pulled sliding rod II 16 slides out under the guiding of the fixed block IV 15 and no longer inserts into the knob 14, the operator can twist the knob 14 according to the adjusted height. The twisted knob 14 will simultaneously drive the cam 13 to rotate through the rotating shaft, causing the rotated cam 13 to press upward against the fixed frame 1, making the fixed frame 1 be lifted from the support plate 10 under the guiding of the support rod 11 until the metal workpiece is lifted to the appropriate height, and then the sliding rod II 16 can be snapped back onto the knob 14, thereby realizing stable adjustment of the processing height of the metal workpiece.

[0029] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
