Description

Technical Field

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

[0002] Metal parts processing refers to the process of shaping metal raw materials into parts or components with specific shapes, sizes, and properties through a series of processes. This type of processing is widely used in industries such as automobiles, aerospace, electronics, machinery manufacturing, and construction. The workpiece is rotated on a lathe, and cutting tools are used to form cylindrical, conical, and other rotating parts. Milling machines are used to cut the workpiece in multiple directions to process planes, grooves, or complex curved surfaces. Drills are used to drill holes in the metal, and grinding wheels are used to precisely machine surfaces to improve surface finish and dimensional accuracy. Fixing devices for metal parts processing are auxiliary tools used to stably clamp metal workpieces during machining to ensure processing accuracy, safety, and efficiency. The existing authorization announcement number CN216464221U discloses a fixing device for processing metal mold parts, including a support foot. A work box is fixedly connected to the top of the support foot. A working cavity is opened inside the work box. An adjustment mechanism and an auxiliary mechanism are provided at the bottom of the working cavity. A support mechanism is provided at the top of the work box. The adjustment mechanism includes a motor, gears, guide teeth, and a moving plate. When fixing is required, the raw material to be processed is placed on the top of the support base plate. Then, the motor is turned on. When the motor is working, it drives the moving base to move towards the center of the top of the work box. When it moves to the left and right sides of the raw material to be processed, the turntable is rotated so that the clamping plate contacts the raw material to be processed and presses it to fix it, thereby performing the fixing work. This device has the advantage of wide applicability and can be used to fix raw materials of different sizes. Existing fixing devices for metal parts processing have the following problems: when processing metal parts, they are only suitable for parts of different widths, their height is limited by the support base plate, their dimensional compatibility is narrow, and their performance is not good. Therefore, we propose a fixing device for metal parts processing. Utility Model Content

[0005] Furthermore, a control switch assembly is provided on the outside of the base, and the input end of the control switch assembly is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0006] Furthermore, it also includes a drive assembly, which includes a bidirectional screw. The bidirectional screw is rotatably connected to the middle of the left and right inner walls of the slide groove. The threaded hole at the middle of the lower end of the T-shaped slider is threadedly connected to the left and right ends of the bidirectional screw to provide a transmission connection.

[0007] Furthermore, the drive assembly also includes a second motor. The left end of the slide is provided with the second motor. The right end of the output shaft of the second motor is fixedly connected to the left end of the bidirectional screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This fixing device for metal parts processing has the following advantages: Driven by motor one, the worm gear and worm wheel cause the double-headed screw two to drive the U-shaped slider to slide in the opposite direction. The U-shaped slider, through the connecting rod and U-shaped block, causes the sliding plate to rise vertically along the guide rod, realizing the height adjustment of the clamping plate. Then, driven by motor two, the double-headed screw one causes the T-shaped slider to slide towards the two guide posts, thereby making the two clamping plates move closer together synchronously, realizing the lateral clamping of the workpiece. When processing metal parts, it can adapt to metal parts of different heights and widths, with stronger size compatibility and better performance. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a fixing device for processing metal parts, including a base 1, the bottom wall of the base 1 is provided with a strip groove 2, and also includes a clamping mechanism 3. The outside of the base 1 is provided with a control switch group 5, and the input end of the control switch group 5 is electrically connected to an external power source. Clamping mechanism 3 includes a U-shaped slider 31, connecting rod 32, U-shaped block 33, guide rod 34, sliding plate 35, guide post 36, T-shaped slider 37, clamping plate 38, and slide groove 39. Guide rods 34 are respectively provided at the four corners of the bottom wall of the base 1. A sliding plate 35 is slidably connected between the guide rods 34. Symmetrical U-shaped sliders 31 are slidably connected inside the strip groove 2. Symmetrical U-shaped blocks 33 are provided at the lower end of the sliding plate 35. Connecting rods 32 are rotatably connected between the lower end of the U-shaped slider 31 and the upper end of the vertically adjacent U-shaped block 33 via pins. A slide groove 39 is provided at the upper end of the sliding plate 35. Symmetrical guide posts 36 are fixedly connected between the left and right inner walls of the slide groove 39. Two guide posts 36 are slidably connected. The device has two symmetrical T-shaped sliders 37, each with a clamping plate 38 at its upper end. (A scale line 1 can be set on the upper end of the base 1, and a scale line 2 can be set on the front side of the T-shaped slider 37. Since the distance between the left side of the left T-shaped slider 37 and the right side of the left clamping plate 38 is constant, and the distance between the right side of the right T-shaped slider 37 and the left side of the right clamping plate 38 is constant, we can set it as 'a'. The width of the workpiece to be fixed is known in advance as 'b'. Based on the comparison between the left side of the left T-shaped slider 37 and the scale line 1, and the comparison between the right side of the right T-shaped slider 37 and the scale line 1, the distance is determined to be 'c' during the adjustment process. When c = b + 2a, the workpiece of that width can be stably clamped. Therefore, during the adjustment process, as long as...) The value of c can be monitored in real time. When adjusting the height, initially, the lowest value of the second scale line on the upper end of the T-slider 37 is aligned with the horizontal plane of the upper end of the base 1. By observing the rise of the T-slider 37 until the second scale line aligns with the horizontal plane of the upper end of the base 1, the workpiece at that height can be clamped. The drive assembly 4 also includes a bidirectional screw 44. The bidirectional screw 44 is rotatably connected to the middle of the left and right inner walls of the slide groove 39. The threaded hole at the lower middle of the T-slider 37 is threaded to the left and right ends of the bidirectional screw 44 respectively. (This connection can be made between the left wall of the slide groove 39 and the left end of the left T-slider 37, between the opposite ends of the two T-slider 37, and between the right end of the right T-slider 37 and the right wall of the slide groove 39.) The drive assembly 4 also includes a second motor 45, which is located at the left end of the slide groove 39. The right end of the output shaft of the second motor 45 is fixedly connected to the left end of the double-direction screw 44. The input end of the second motor 45 is electrically connected to the output end of the control switch group 5. The drive assembly 4 also includes a second double-direction screw 46, which is rotatably connected between the left and right inner walls of the strip groove 2. The threaded opening at the lower middle of the U-shaped slider 31 is threadedly connected to the left and right ends of the second double-direction screw 46.(A second bellows can be fixedly connected between the left wall of the strip groove 2 and the left end of the left U-shaped slider 31, between the opposite ends of the two U-shaped sliders 31, and between the right end of the right U-shaped slider 31 and the right wall of the strip groove 2. The second bellows are respectively sleeved on the outside of the second bidirectional screw 46. The second bellows will protect the second bidirectional screw 46, prevent debris from entering the interior of the second bidirectional screw 46, and ensure the sealing and lubrication of the second bidirectional screw 46.) The drive assembly 4 also includes a worm gear 42 and a worm 43. The worm gear 42 is fixedly sleeved in the middle of the second bidirectional screw 46. The worm 43 is rotatably connected in the middle between the front and rear inner walls of the strip groove 2. The worm gear 42 and the worm 43 are meshed. The drive assembly 4 also includes The system includes a motor 41, which is located in the middle of the front end of the strip groove 2. The rear end of the output shaft of the motor 41 is fixedly connected to the front end of the worm 43. The input end of the motor 41 is electrically connected to the output end of the control switch group 5. By adjusting the control switch group 5, the motor 41 operates, and the output shaft of the motor 41 drives the worm 43 to rotate. Since the worm 43 meshes with the worm wheel 42, the rotational motion of the worm 43 is converted into the rotational motion of the worm wheel 42, which in turn drives the bidirectional screw 46 to rotate synchronously in the strip groove 2. The left and right ends of the bidirectional screw 46 have opposite thread directions and are respectively threaded to the threaded openings at the lower ends of the U-shaped sliders 31 that are symmetrically positioned on the left and right sides of the strip groove 2. When the bidirectional screw 46 rotates, the left and right ends rotate in opposite directions. Two U-shaped sliders 31 slide in opposite directions along the strip groove 2. The lower end of the U-shaped slider 31 is connected to the U-shaped block 33 at the lower end of the sliding plate 35 via a connecting rod 32 through a pin. When the U-shaped slider 31 slides in the opposite direction, the connecting rod 32 pushes the U-shaped block 33 upward through the pin, thereby causing the sliding plate 35 to rise vertically along the guide rods 34 at the four corners. When the U-shaped slider 31 slides in the opposite direction, the connecting rod 32 pulls the U-shaped block 33 downward, and the sliding plate 35 descends vertically along the guide rods 34. Through this process, the height of the clamping plate 38 can be precisely adjusted so that the workpiece height is adapted to the working position of the processing equipment. Then, by controlling the control switch group 5, the second motor 45 operates, and the output shaft of the second motor 45 drives the bidirectional screw. Rod 44 rotates within slide groove 39. Symmetrical T-shaped sliders 37 within slide groove 39 are slidably connected to symmetrical guide posts 36. The threaded holes at the lower center of the T-shaped sliders 37 are threaded to the left and right ends of the bidirectional screw 44. When the bidirectional screw 44 rotates, the two T-shaped sliders 37 slide towards each other along guide posts 36. Since clamping plates 38 are fixed to the upper ends of the T-shaped sliders 37, the opposing sliding of the T-shaped sliders 37 causes the two clamping plates 38 to move closer together, achieving lateral clamping of the workpiece. Reverse sliding causes the clamping plates 38 to move away, allowing the workpiece to be released and removed. Guide posts 36 ensure the straightness of the sliding of the clamping plates 38, preventing skewing during clamping and improving clamping stability.

[0016] The working principle of the fixing device for metal parts processing provided by this utility model is as follows: When processing metal parts, the motor 41 is operated by adjusting the control switch group 5. The output shaft of the motor 41 drives the worm 43 to rotate. Since the worm 43 meshes with the worm wheel 42, the rotational motion of the worm 43 is converted into the rotational motion of the worm wheel 42, which in turn drives the bidirectional screw 46 to rotate synchronously in the slot 2. The threads of the left and right ends of the bidirectional screw 46 are opposite and respectively mesh with the slot 2. The lower ends of the symmetrical U-shaped sliders 31 are threaded together. When the bidirectional screw 46 rotates, the two U-shaped sliders 31 slide in opposite directions along the groove 2. The lower ends of the U-shaped sliders 31 are connected to the U-shaped blocks 33 at the lower end of the sliding plate 35 via pins and connecting rods 32. When the U-shaped sliders 31 slide in the opposite direction, the connecting rods 32 push the U-shaped blocks 33 upward through the pins, thereby causing the sliding plate 35 to rise vertically along the guide rods 34 at the four corners. When the U-shaped sliders 31 slide in the opposite direction, the connecting rods 32 push the U-shaped blocks 33 upward through the pins, thereby causing the sliding plate 35 to rise vertically along the guide rods 34 at the four corners. 2. Pulling the U-shaped block 33 downwards causes the sliding plate 35 to descend vertically along the guide rod 34. Through this process, the height of the clamping plate 38 can be precisely adjusted to match the workpiece height to the working position of the processing equipment. Then, by controlling the control switch group 5, the second motor 45 operates. The output shaft of the second motor 45 drives the bidirectional screw 44 to rotate within the slide groove 39. The left and right symmetrical T-shaped sliders 37 within the slide groove 39 are slidably connected to the front and rear symmetrical guide posts 36, and the threaded holes at the lower center of the T-shaped sliders 37 are respectively connected to the double... The screw 44 is threaded to both ends. When the screw 44 rotates, the two T-shaped sliders 37 slide towards each other along the guide post 36. Since the clamping plate 38 is fixed to the upper end of the T-shaped slider 37, the sliding of the T-shaped slider 37 towards each other will cause the two clamping plates 38 to move closer to each other in sync, thereby achieving lateral clamping of the workpiece. The reverse sliding will cause the clamping plates 38 to move away from each other, thereby releasing and removing the workpiece. The guide post 36 ensures the straightness of the sliding of the clamping plate 38, avoids skewing during clamping, and improves clamping stability.

[0017] It is worth noting that the motor 41 and motor 45 disclosed in the above embodiments can both be selected from 35BYJ412H. The control switch group 5 is provided with a switch button that corresponds one-to-one with motor 41 and motor 45 and is used to control their switching operation.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
