Description

Technical Field

[0001] This utility model relates to the field of anvil assembly technology, specifically a quick assembly and positioning fixture for anvils. Background Technology

[0002] Anchor assembly is a process in the production of machinery or precision equipment where the anchor, a core component, is precisely combined, positioned, and fixed with other supporting components according to design standards. Its core requirement is to ensure the positional accuracy, connection stability, and coordination with the corresponding moving parts of the anchor after assembly, which directly affects the final functional reliability of the equipment.

[0003] The existing Chinese patent publication number CN222124278U, entitled "A Fixture for Clamping and Measuring Anchor Seats," explicitly states in its abstract that "This utility model discloses a fixture for clamping and measuring anchor seats, relating to the field of measuring fixture technology. It includes a fixture body, a top block, and an elastic support member. The top wall of the fixture body has a cavity, and the fixture body has a first limiting end formed by the cavity. The top block is located within the cavity, and the elastic support member is elastically supported at the bottom end of the top block. The top wall of the fixture body extends upward to form a limiting seat." A second limiting end is formed on the side wall of the limiting seat facing the center of the cavity near the top. When the anvil is clamped on the fixture body, the anvil is placed on the top block, and the elastic support member presses against the top block upwards until the top block abuts against the first limiting end. At the same time, the anvil abuts against the second limiting end, and at this time, the overall height of the anvil is higher than the height of the top wall of the fixture body. This utility model has the effect of measuring the product dimensions from all angles by clamping the part (anvil) at one time, realizing the measurement of the entire product with one fixture, and improving the measurement efficiency and measurement accuracy.

[0004] However, in this technology, the pressure block used to press the anvil seat relies solely on its own weight to achieve the pressing and positioning of the anvil seat. When faced with anvil seats of different weights and specifications or when subjected to slight external interference, insufficient pressing force and weak fit may occur, potentially affecting the clamping stability. At the same time, the support block and top block used to support the anvil seat are fixedly connected structures, and the shape of the groove on its surface that adapts to the anvil seat cannot be flexibly adjusted. When it is necessary to adapt to anvil seats of different models and sizes, it is not possible to directly replace the matching support block. The original support block must be completely disassembled before replacement, which is a cumbersome operation process and is not conducive to improving the efficiency of assembly or measurement. Utility Model Content

[0005] The purpose of this utility model is to provide a quick assembly and positioning fixture for anvil seats, so as to solve the problem mentioned in the background art that the pressure block used to press the anvil seat relies solely on its own gravity to achieve the pressing and positioning of the anvil seat, and that when it is necessary to adapt to anvil seats of different models and different external dimensions, it is impossible to directly replace the matching support block.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A quick assembly and positioning fixture for anvil seats includes a support base, a rotating frame is provided on the support base, a rotating rod is rotatably provided inside the rotating frame, and hexagonal plates are provided on both sides of the rotating rod. Each surface of the hexagonal plate is provided with a support groove of different types. The support base is also provided with a mounting bracket, a pressure plate is slidably disposed inside the mounting bracket, a screw hole is provided on the top of the mounting bracket, and a screw rod is disposed inside the screw hole.

[0007] In a preferred embodiment of this utility model, a hexagonal groove is provided behind the rotating frame, and a hexagonal block is slidably disposed inside the hexagonal groove.

[0008] In a preferred embodiment of this utility model, a hexagonal opening is provided at the rear of the rotating frame, and the hexagonal block is assembled and disassembled in the hexagonal opening.

[0009] In a preferred embodiment of this utility model, a spring is provided at the rear of the hexagonal groove, and a hexagonal block is connected to the front of the spring.

[0010] In a preferred embodiment of this utility model, a pull rod is provided behind the hexagonal block, and the pull rod extends to the rear of the outer side of the hexagonal groove.

[0011] In a preferred embodiment of this utility model, the screw is threadedly connected to the screw hole, and the bottom of the screw is rotatably connected to the pressure plate.

[0012] In a preferred embodiment of this utility model, a baffle is provided at the top rear of the rotating frame, and the baffle is located behind the support groove directly above.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: This device, by setting up a structure in which a screw and a pressure plate work together, abandons the existing technology that relies solely on the weight of the pressure block to press the anvil. By rotating the screw, the pressure plate can be actively driven to apply pressure to the anvil. Regardless of the anvil's weight or size or the slight external interference, it can ensure that the anvil is firmly pressed, effectively solving the problems of insufficient pressing force and poor adhesion in the existing technology. At the same time, by setting different types of support grooves on each side of the hexagonal plate to replace the fixed support block in the existing technology, when it is necessary to adapt to different types and sizes of anvils, it is only necessary to pull the pull rod to release the limit and rotate the hexagonal plate to switch to the appropriate support groove. There is no need to disassemble the original support block, making the operation convenient and effectively solving the problems of cumbersome operation and lack of efficiency in adapting different types of anvils in the existing technology.

[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses a quick assembly and positioning fixture for anvil seats, comprising a support base 1 made of 45# steel, serving as the bottom support structure for supporting the overall structure. A rotating frame 11, made of aluminum alloy, is mounted on the support base 1. A rotating rod 12, made of stainless steel, is rotatably mounted inside the rotating frame 11. Hexagonal plates 13, made of hard alloy, are located on both sides of the rotating rod 12. Each surface of the hexagonal plates 13 has a support groove 14 of different sizes, which replaces the support block in the prior art patent to accommodate different anvil seat models. A baffle 34, made of aluminum alloy, is located at the top rear of the rotating frame 11, positioned behind the support groove 14, to limit the rearward movement of the anvil seat and prevent it from shifting backward during assembly.

[0020] A hexagonal slide groove 2 is provided at the rear of the rotating frame 11. The hexagonal slide groove 2 is made of the same aluminum alloy as the rotating frame 11. A hexagonal block 23 is slidably arranged inside the hexagonal slide groove 2. The hexagonal block 23 is made of stainless steel. When the hexagonal block 23 is inserted into the hexagonal opening 21, a part of it remains in the hexagonal groove to ensure the positioning stability of the hexagonal block 23 for the rotating rod 12. A hexagonal opening 21 is provided at the rear of the rotating frame 11. The size of the hexagonal opening 21 is adapted to the hexagonal block 23. The hexagonal block 23 is installed and removed in the hexagonal opening 21. When a certain support groove 14 is facing directly upward, the hexagonal block 23 will be connected with the hexagonal opening 21, thereby fixing the rotating rod 12. A spring 22 is installed at the rear of the hexagonal slide 2. The spring 22 is made of piano wire and its model is GB / T2089-2009. The front of the spring 22 is connected to the hexagonal block 23. A pull rod 24 is installed at the rear of the hexagonal block 23. The pull rod 24 is made of stainless steel and extends to the rear of the outer side of the hexagonal slide 2, making it convenient for the operator to pull the hexagonal block 23 to move.

[0021] The support base 1 is also equipped with a mounting bracket 3, which is made of aluminum alloy. A pressure plate 33 is slidably installed inside the mounting bracket 3. The pressure plate 33 is made of 45 steel. The top of the mounting bracket 3 is equipped with a screw 31, which is an anti-loosening thread with a model of M12×1.75. A screw 32 is installed inside the screw 31. The screw 32 is made of stainless steel and its model matches that of the screw 31, which is M12×1.75. The screw 32 is threadedly connected to the screw 31. The bottom of the screw 32 is rotatably connected to the pressure plate 33. By rotating the screw 32, the pressure plate 33 can be driven to slide up and down along the inside of the mounting bracket 3. When the operator rotates the screw 32 to drive the pressure plate 33 to press the anvil, the clamping force can be controlled by adjusting the number of rotations of the screw 32. Since the screw 31 is an M12×1.75 anti-loosening thread, the distance that the pressure plate 33 moves down with each rotation of the screw 32 is fixed. The operator can preset the upper limit of the number of rotations of the screw 32 according to the material hardness of the anvil. At the same time, when the operator rotates the screw 32, if a significant increase in resistance is felt, it indicates that the pressure plate 33 has reached the appropriate clamping degree, and the operator should stop rotating the screw 32 to avoid damage to the anvil due to excessive clamping force.

[0022] The working principle of this utility model is as follows: When using the quick assembly positioning fixture with the anvil, first pull the pull rod 24. The pull rod 24 drives the hexagonal block 23 to move backward in the hexagonal slide groove 2, while compressing the spring 22, so that the hexagonal block 23 disengages from the hexagonal opening 21 on the rotating frame 11, releasing the limit on the rotating rod 12; then rotate the rotating rod 12, which drives the hexagonal plates 13 on both sides to rotate, rotating the support groove 14 on the hexagonal plate 13 that matches the model of the anvil to be assembled to the top position. Release the pull rod 24, the spring 22 returns to its original position and pushes the hexagonal block 23 forward, so that part of the hexagonal block 23 is inserted. The hexagonal opening 21 is inserted, with a portion remaining in the hexagonal sliding groove 2, thus fixing the rotating rod 12 to the hexagonal plate 13. Next, the anvil to be assembled is placed in the support groove 14 directly above, with the rear of the anvil fitting against the baffle 34, completing the initial positioning of the anvil. Finally, the screw 32 is rotated, moving downward along the screw opening 31, causing the pressure plate 33 to slide downward along the inside of the mounting bracket 3 until the pressure plate 33 presses the anvil, completing the assembly and positioning of the anvil. When it is necessary to remove the anvil, the screw 32 is rotated counterclockwise, causing the pressure plate 33 to move upward, releasing the pressure on the anvil, and the anvil can then be removed from the support groove 14.
