Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to an adjustable fixture for machining mold steel. Background Technology

[0002] Mold steel machining fixtures are tooling devices specifically designed for positioning, clamping, and supporting mold steel materials during machining. They feature high rigidity, high precision, and good wear resistance, and are mainly used in machining processes such as turning, milling, drilling, and electrical discharge machining to ensure the stability and machining accuracy of mold steel during processing.

[0003] Existing machining fixtures typically use clamping devices to fix the mold steel material onto the fixture, enabling machining operations on the top. However, when machining the bottom of the mold steel is required, it is often necessary to remove it from the fixture and re-clamp it. This process increases the number of steps, prolongs the machining time, and directly affects the overall machining efficiency. In actual production, machining efficiency is an important indicator for evaluating the quality of equipment and processes. Frequent loading, unloading, and flipping not only consume more time but also reduce equipment utilization. Therefore, the limitations of existing fixture structures on machining efficiency are becoming increasingly prominent when facing the multi-faceted machining requirements of mold steel.

[0004] In view of this, we propose an adjustable fixture for machining mold steel. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable fixture for machining mold steel. This adjustable fixture for machining mold steel solves the problem that existing machining fixtures need to be reloaded and flipped when machining the bottom of mold steel, which reduces the overall machining efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable fixture for machining mold steel includes a base and a reciprocating component. The inner wall of the base is slidably connected to the reciprocating component. Both the base and the reciprocating component are provided with vise ports, two of which are symmetrically arranged. An adjustment mechanism is provided on each vise port. The adjustment mechanism includes a hollow cylindrical block rotatably connected to the inner wall of the vise port. A rigid plate is fixedly connected to the outer wall of the hollow cylindrical block. An opening groove is formed on the outer wall of the rigid plate. An adjusting screw is threadedly connected to the inner wall of the rigid plate. A rigid strip is rotatably connected to the bottom of the adjusting screw. A guide rod is fixedly connected to the top of the rigid strip. The outer wall of the guide rod is slidably connected to the rigid plate. A spring is provided on the inner wall of the hollow cylindrical block. One end of the spring is fixedly connected to the inner wall of the hollow cylindrical block, and the other end of the spring is fixedly connected to a rectangular block. A pull rod is rotatably connected to the outer wall of the rectangular block. A disc block is fixedly connected to the outer wall of the pull rod. A positioning pin is fixedly connected to the outer wall of the disc block. A positioning groove is provided on the vise port. A locking mechanism is provided on the base component and the reciprocating component. The locking mechanism is used to provide a visible clamping force to the vise port.

[0008] Preferably, the reciprocating component is slidably connected to the base component via a slide rail structure, and the top of the adjusting screw is provided with an anti-slip knob for easy manual rotation.

[0009] Preferably, the surface of the rigid plate is provided with anti-slip stripes to enhance the friction of the workpiece, and the outer wall of the hollow cylindrical block is provided with a limiting flange to prevent it from sliding axially.

[0010] Preferably, the outer side of the positioning post is provided with a guide slope to facilitate smooth insertion into the positioning groove, and the guide rod is configured as a double rod structure to improve the stability of up and down movement.

[0011] Preferably, the locking mechanism includes a locking screw, which is threadedly connected to the inner wall of the base component. A ring component is rotatably connected to the outer wall of the locking screw. A second spring is provided on the outer wall of the ring component. One end of the second spring is fixedly connected to the outer wall of the ring component, and the other end of the second spring is fixedly connected to the inner wall of the base component.

[0012] Preferably, the outer wall of the annular component is fixedly connected to a protrusion, and the outer wall of the reciprocating component is provided with a scale.

[0013] Preferably, the protrusion is shaped as a raised ridge with an arrow pointing part, and a transparent dust cover is provided between the protrusion and the scale.

[0014] By employing the above technical solution, this utility model provides an adjustable fixture for machining mold steel. It possesses at least the following beneficial effects:

[0015] 1. This utility model incorporates an adjustment mechanism. When the bottom of a workpiece needs to be processed, the pull rod is pulled and then rotated. Finally, the pull rod is released, and under the action of the spring, the rectangular block, pull rod, disc block, and positioning post move towards the positioning groove, causing the positioning post to engage with the positioning groove. This positions the rigid plate and the workpiece, which is positioned against the rigid plate. At this point, the bottom of the workpiece can be processed, allowing the bottom processing to be completed without disassembly, reducing the time spent on frequent loading and unloading, and thus improving overall processing efficiency.

[0016] 2. This utility model incorporates a locking mechanism. When the locking screw is rotated, it moves closer to the base component due to the threaded connection between the locking screw and the base component. This causes the locking screw to pull the ring component, which in turn pulls the spring. The spring then drives the reciprocating component, which in turn moves the top vise ports closer together. Traditional vises experience sudden changes in force during clamping, which can easily damage the workpiece surface. However, the elastic stroke of the spring can absorb some of the clamping impact, achieving stable clamping. This design is suitable for high-precision workpieces such as mold steel.

[0017] 3. This utility model has a locking mechanism. When the ring component drives the second spring to stretch, the second spring drives the protruding block to move relative to the scale, which serves to show the degree of stretching of the second spring. By observing the position of the protruding block on the scale, the degree of stretching of the second spring can be judged intuitively, which indirectly reflects the clamping force of the vise and avoids damage to the workpiece or insecure clamping due to clamping too tightly or too loosely.

[0025] 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.

[0026] Please see Figure 1 - Figure 5As shown, this utility model provides a technical solution: an adjustable fixture for processing mold steel, including a base 1 and a reciprocating component 2. The inner wall of the base 1 is slidably connected to the reciprocating component 2. Both the base 1 and the reciprocating component 2 are provided with vise ports 3, and two vise ports 3 are symmetrically arranged. An adjustment mechanism 4 is provided on the vise port 3. The adjustment mechanism 4 includes a hollow cylindrical block 41, which is rotatably connected to the inner wall of the vise port 3. A rigid plate 42 is fixedly connected to the outer wall of the hollow cylindrical block 41. An opening groove 43 is opened on the outer wall of the rigid plate 42. An adjustment screw 44 is threadedly connected to the inner wall of the rigid plate 42. A rigid strip 45 is rotatably connected to the bottom of the screw 44, and a guide rod 46 is fixedly connected to the top of the rigid strip 45. The outer wall of the guide rod 46 is slidably connected to the rigid plate 42. A spring 47 is provided on the inner wall of the hollow cylindrical block 41. One end of the spring 47 is fixedly connected to the inner wall of the hollow cylindrical block 41, and the other end of the spring 47 is fixedly connected to a rectangular block 48. A pull rod 49 is rotatably connected to the outer wall of the rectangular block 48, and a disc block 410 is fixedly connected to the outer wall of the pull rod 49. A positioning post 411 is fixedly connected to the outer wall of the disc block 410. A positioning groove is provided on the vise port 3 for docking with the positioning post 411. The mold steel workpiece is placed between two rigid plates 42. Then, the two vise ports 3 are brought closer together until the vise ports 3 cause the rigid plates 42 to laterally contact the workpiece. At this point, rotating the adjusting screw 44 causes the rigid strip 45 to vertically contact the workpiece downwards, thus stably fixing the workpiece. The top of the workpiece is then machined. When machining the bottom of the workpiece is required, pulling the pull rod 49 causes the rectangular block 48 to compress the spring 47. At this time, the pull rod 49 causes the disc block 410 and the positioning pin 411 to move away from the positioning groove, so that the positioning pin 411 is no longer inserted into the positioning groove. Then, rotating the pull rod 49... 9 drives the rectangular block 48 to rotate, which in turn drives the hollow cylindrical block 41 and the rigid plate 42 to rotate, causing the workpiece on the rigid plate 42 to rotate half a turn. Then, the pull rod 49 is released, and under the action of the spring 47, the rectangular block 48, the pull rod 49, the disc block 410, and the positioning pin 411 move towards the positioning groove, so that the positioning pin 411 is inserted into the positioning groove, thereby positioning the rigid plate 42. The workpiece that is positioned against the rigid plate 42 is also positioned. At this time, the bottom of the workpiece can be processed. The base part 1 and the reciprocating part 2 are equipped with a locking mechanism 5, which is used to provide a visible clamping force to the vise port 3.

[0027] The reciprocating component 2 is slidably connected to the base component 1 via a slide rail structure. The top of the adjusting screw 44 is equipped with an anti-slip knob for easy manual rotation. The surface of the hard plate 42 is provided with anti-slip stripes to enhance the friction of the workpiece. The outer wall of the hollow cylindrical block 41 is provided with a limiting flange to prevent it from sliding axially. The outer side of the positioning column 411 is provided with a guide slope to facilitate smooth insertion into the positioning groove. The guide rod 46 is set as a double rod structure to improve the stability of up and down movement.

[0028] The locking mechanism 5 includes a locking screw 51, which is threadedly connected to the inner wall of the base component 1. A ring component 52 is rotatably connected to the outer wall of the locking screw 51. A second spring 53 is disposed on the outer wall of the ring component 52. One end of the second spring 53 is fixedly connected to the outer wall of the ring component 52, and the other end is fixedly connected to the inner wall of the base component 1. Rotating the locking screw 51 causes it to move closer to the base component 1 due to the threaded connection. This causes the locking screw 51 to pull the ring component 52, which in turn pulls the second spring 53. The second spring 53 then drives the reciprocating component 2, which in turn moves the top vise ports 3 closer together. Traditional vises experience sudden force changes during clamping, which can easily damage the workpiece surface. The elastic stroke of the second spring 53 can absorb some of the clamping force. This vise provides stable clamping while maintaining impact, making it suitable for high-precision workpieces such as mold steel. A protruding block 54 is fixedly connected to the outer wall of the ring 52, and a scale 55 is provided on the outer wall of the reciprocating part 2. When the ring 52 drives the second spring 53 to stretch, the second spring 53 drives the protruding block 54 to move relative to the scale 55, thus displaying the degree of stretching of the second spring 53. By observing the position of the protruding block 54 on the scale 55, the degree of stretching of the second spring 53 can be intuitively judged, indirectly reflecting the clamping force of the vise. This prevents damage to the workpiece or insecure clamping due to excessive or insufficient clamping. The protruding block 54 is a raised ridge with an arrow indicator for easy alignment and reading of the scale position. A transparent dust cover is provided between the protruding block 54 and the scale 55 to prevent dust or metal shavings from obscuring the scale display.

[0029] In use, the adjustable fixture for machining mold steel of this utility model has a positioning groove for docking with the positioning post 411. The mold steel workpiece is placed between two rigid plates 42, and then the two vise ports 3 are brought closer together until the vise ports 3 cause the rigid plates 42 to laterally contact the workpiece. At this point, rotating the adjusting screw 44 causes the rigid strip 45 to vertically contact the workpiece downwards, thus stably fixing the workpiece. Then, the top of the workpiece is machined. When machining the bottom of the workpiece is required, pulling the pull rod 49 causes the rectangular block 48 to compress the spring 47. At this time, the pull rod 49 drives the disc block 410 and the positioning post 411. Move the device away from the positioning slot so that the positioning pin 411 is no longer inserted into the positioning slot. Then rotate the pull rod 49, which drives the rectangular block 48 to rotate. The rectangular block 48 drives the hollow cylindrical block 41 and the rigid plate 42 to rotate, causing the workpiece on the rigid plate 42 to rotate half a turn. Then release the pull rod 49. Under the action of the spring 47, the rectangular block 48, the pull rod 49, the disc block 410, and the positioning pin 411 move towards the positioning slot, so that the positioning pin 411 is inserted into the positioning slot, thus positioning the rigid plate 42. The workpiece that is positioned against the rigid plate 42 is also positioned. At this time, the bottom of the workpiece can be processed.

[0030] Rotating the locking screw 51 causes it to move closer to the base piece 1 due to its threaded connection with the base piece 1. This causes the locking screw 51 to pull the ring piece 52, which in turn pulls the spring 53. The spring 53 then drives the reciprocating piece 2, which in turn moves the top vise ports 3 closer together. Traditional vises experience sudden changes in force during clamping, which can easily damage the workpiece surface. However, the elastic stroke of the spring 53 can absorb some of the clamping impact, achieving stable clamping. This method is suitable for high-precision workpieces such as mold steel.

[0031] When the ring 52 drives the second spring 53 to stretch, the second spring 53 drives the protrusion 54 to move relative to the scale 55, which serves to show the degree of stretching of the second spring 53. By observing the position of the protrusion 54 on the scale 55, the degree of stretching of the second spring 53 can be judged intuitively, which indirectly reflects the clamping force of the vise and avoids damage to the workpiece or insecure clamping due to clamping too tightly or too loosely.
