Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a positioning fixture for metal processing. Background Technology

[0002] Metalworking, or metal processing for short, refers to the production activities of humans processing materials composed primarily of metallic elements or possessing metallic properties. It is a craft technology that transforms metallic materials into items, parts, and components, encompassing large parts for bridges and ships, as well as minute components for engines, jewelry, and watches. It is widely used in various fields such as science, industry, art, and handicrafts.

[0003] Most existing metalworking positioning fixtures use two clamping blocks to hold the workpiece during use.

[0004] Traditional positioning fixtures for metal processing have the following problems: the clamping surfaces of existing clamping blocks are mostly straight, which cannot be well adapted to the clamping and positioning of workpieces. This causes hardware parts of different shapes to slip easily during processing, resulting in poor clamping and positioning effects and unsatisfactory processing results. To address this, we propose a positioning fixture for metal processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a positioning fixture for metal processing, which can realize the positioning and clamping of metal workpieces of different shapes, avoid the slippage of metal workpieces during processing, improve the clamping and positioning effect of metal workpieces, and ensure the processing quality of metal workpieces, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for metal processing, comprising a machine base, a fixing mechanism, and a positioning mechanism;

[0007] Machine base: It is equipped with support legs at its lower end;

[0008] Fixed mechanism: It includes a slide plate, a support block and a slide rod. The slide rod is fixedly connected to the front and rear ends of the machine tool. The slide plate is slidably connected to the left and right ends of the two slide rods. The front and rear ends of the upper surface of the slide plate are respectively provided with corresponding support blocks. The upper ends of the front and rear adjacent support blocks are fixedly connected with rectangular strips.

[0009] Positioning mechanisms: These are respectively set inside the rectangular bars to position and clamp metal workpieces of different shapes, preventing slippage of the metal workpieces during processing, improving the clamping and positioning effect of the metal workpieces, and ensuring the processing quality of the metal workpieces.

[0010] Furthermore, a control switch group is provided on the left end of the front side of the machine tool. The input end of the control switch group is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0011] Furthermore, the fixing mechanism also includes a rotating shaft, a rotating plate, a connecting rod, a telescopic rod, and a spring.

The front and rear ends of the rotating plate are respectively rotatably connected to the connecting rods via pins. The ends of the connecting rods away from the center of the machine base are respectively rotatably connected to the middle of the adjacent slide plates via pins. The bottom wall of the machine base is provided with symmetrical vertical plates. Telescopic rods are fixedly connected between the two slide plates and the horizontally adjacent vertical plates. Springs are respectively sleeved on the outside of the telescopic rods to achieve clamping.

[0012] Furthermore, the fixing mechanism also includes a motor, which is located at the lower end of the machine base. The upper end of the output shaft of the motor is fixedly connected to the lower end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the control switch group to provide a fixed drive.

[0013] Furthermore, the positioning mechanism includes a bidirectional lead screw and a slider. The bidirectional lead screw is rotatably connected to the inside of the rectangular bar, and the front and rear ends of the bidirectional lead screw are threadedly connected to sliders.

[0017] 1. First, place the metal workpiece on the upper end of the machine. By adjusting the control switch group, motor one starts running. The output shaft of motor one drives the rotating shaft to rotate. The rotating shaft rotates the rotating plate, which in turn drives the connecting rods at both ends to rotate. The connecting rods pull the two slide plates to slide towards each other on the slide rod, thereby making the innermost positioning post contact the outer surface of the metal workpiece and fix the metal workpiece, thus realizing the positioning and clamping of metal workpieces of different shapes.

[0018] 2. Next, by adjusting the control switch group, motor two operates, and the output shaft of motor two drives the bidirectional lead screw to rotate, which in turn drives the threaded slider to slide towards each other. Then, the outermost positioning pin contacts the outer surface of the metal workpiece under the rotation of the rotating pin. Then, the next step of processing the metal workpiece is carried out. After processing, by adjusting the control switch group, motor two operates, and the output shaft of motor two rotates counterclockwise. Then, the positioning pin is reset under the rebound of the torsion spring. The positioning pin will disengage from the metal workpiece, avoiding slippage of the metal workpiece during processing, improving the clamping and positioning effect of the metal workpiece, and ensuring the processing quality of the metal workpiece.

Rectangular bars 5 are fixedly connected to the upper ends of adjacent support blocks 46. Fixed mechanism 4 also includes a rotating shaft 42, a rotating plate 43, a connecting rod 44, a telescopic rod 48, and a spring 49. The lower end of the rotating shaft 42 is rotatably connected to the center of the bottom wall of the machine base 1. The upper end of the rotating shaft 42 is fixedly connected to the rotating plate 43. Connecting rods 44 are rotatably connected to the front and rear ends of the rotating plate 43 via pins. The end of the connecting rod 44 furthest from the center of the machine base 1 is rotatably connected to the middle of the adjacent slide plate 45 via pins. The bottom wall of the machine base 1 has symmetrical upright plates. Two sliding plates 45 are fixedly connected to the adjacent horizontal vertical plates with telescopic rods 48. Springs 49 are respectively sleeved on the outside of the telescopic rods 48. The fixing mechanism 4 also includes a motor 41. The motor 41 is set at the lower end of the machine base 1. The upper end of the output shaft of the motor 41 is fixedly connected to the lower end of the rotating shaft 42. The input end of the motor 41 is electrically connected to the output end of the control switch group 3. First, the metal workpiece is placed at the upper end of the machine base 1. By adjusting the control switch group 3, the motor 41 is turned on. The output shaft of the motor 41 drives the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the rotating plate 43 to rotate. The rotating plate 43 will drive the connecting rods 44 at both ends to rotate. The connecting rods 44 will pull the two sliding plates 45 to slide towards each other on the sliding rod 47, so that the innermost positioning post 68 contacts the outer surface of the metal workpiece and fixes the metal workpiece.

[0028] Positioning mechanism 6: It is respectively set inside the rectangular bar 5. The positioning mechanism 6 includes a two-way lead screw 62 and a slider 63. The two-way lead screw 62 is rotatably connected to the inside of the rectangular bar 5. The front and rear ends of the two-way lead screw 62 are respectively threaded to the slider 63. The slider 63 is slidably connected to the inside of the rectangular bar 5. The positioning mechanism 6 also includes a rectangular block 64, a rotating column 65, a torsion spring 66, a triangular support rod 67, and a positioning post 68. The side of the slider 63 near the center of the machine base 1 is fixedly connected to the rectangular block 64. The middle part of the rectangular block 64 is rotatably connected to the rotating column 65. The lower end of the rotating column 65 is fixedly connected to the triangular support rod 67. The front and rear ends of the triangular support rod 67 are respectively rotatably connected to the positioning post 68. The upper end of the rotating column 65 is fitted with a torsion spring 66. The upper end of the torsion spring 66 is fixedly connected to the top of the adjacent rectangular block 64. The lower end of the torsion spring 66 is fixedly connected to the outer wall of the adjacent rotating column 65. The fixed connection and positioning mechanism 6 also includes a second motor 61, which is respectively located at the rear end of the rectangular bar 5. The front end of the output shaft of the second motor 61 is fixedly connected to the rear end of the adjacent bidirectional lead screw 62. The input end of the second motor 61 is electrically connected to the output end of the control switch group 3. Then, by adjusting the control switch group 3, the second motor 61 runs, and the output shaft of the second motor 61 drives the bidirectional lead screw 62 to rotate, which in turn drives the threaded slider 63 to slide towards each other. Then, the outermost positioning post 68 contacts the outer surface of the metal workpiece under the rotation of the rotating post 65. Then, the next step of processing the metal workpiece is carried out. After the processing is completed, by adjusting the control switch group 3, the second motor 61 runs, and the output shaft of the second motor 61 rotates counterclockwise, which causes the positioning post 68 to reset under the rebound action of the torsion spring 66. The positioning post 68 will then be separated from the metal workpiece.

[0029] The working principle of the positioning fixture for metal processing provided by this utility model is as follows: First, the metal workpiece is placed on the upper end of the machine base 1. By controlling the control switch group 3, the motor 41 is turned on. The output shaft of the motor 41 drives the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the rotating plate 43 to rotate. The rotating plate 43 will drive the connecting rods 44 at both ends to rotate. The connecting rods 44 will pull the two sliding plates 45 to slide towards each other on the sliding rod 47, thereby making the innermost positioning post 68 contact the outer surface of the metal workpiece and fix the metal workpiece. Then, by controlling the control switch group 3... With proper control, motor 61 operates, and its output shaft drives the bidirectional lead screw 62 to rotate, which in turn drives the threaded slider 63 to slide towards each other. The outermost positioning pin 68 then contacts the outer surface of the metal workpiece under the rotation of the rotating column 65, allowing for further processing of the metal workpiece. After processing, by adjusting the control switch group 3, motor 61 operates again, and its output shaft rotates counterclockwise. This causes the positioning pin 68 to reset under the rebound of the torsion spring 66, disengaging it from the metal workpiece.

[0030] It is worth noting that the motor 41 and motor 61 disclosed in the above embodiments can be either 21D180M-O160030B-E or KS-370. The control switch group 3 is provided with switch buttons corresponding to motor 41 and motor 61 for controlling their switching operation.
