Description

Technical Field

[0001] The invention relates to the technical field of angle-adjustable milling machine fixtures, and in particular to an angle-adjustable milling machine fixture. Background Art

[0002] The milling machine fixture is a special tool used to fix and position the workpiece on the milling machine. Its main function is to ensure that the workpiece can be stably and accurately maintained in the desired position during the milling process, thereby improving the processing accuracy and efficiency. The milling machine fixture is usually composed of a fixed seat, a clamping device, a positioning element, etc., and can be designed and customized according to the shape, size and processing requirements of the workpiece. Common types of fixtures include ordinary fixtures, special fixtures, indexing fixtures, etc. In mechanical processing, especially in milling, drilling, boring and other processes, the use of fixtures is an important means to ensure processing accuracy and operational safety. By reasonably designing the fixture, the deformation, movement or vibration of the workpiece during the processing can be minimized, thereby ensuring the processing quality and consistency of the workpiece. Milling machine fixtures are widely used in various industrial fields, such as automobiles, aerospace, mold manufacturing and other industries. With the development of automation technology, the design of fixtures has also paid more and more attention to intelligence and automation to meet the needs of modern manufacturing for high-precision and high-efficiency production.

[0003] In the prior art, there is a Chinese patent with publication number: "CN220863352U", a milling machine fixture, including a support plate and a base plate, the base plate is detachably connected to the support plate, the support plate is used to be fixed to the milling machine, a mounting frame, a first limit member and a second limit member, the mounting frame is fixed to the base plate, and the mounting frame is a hollow structure with an open top, along the length direction of the base plate, the first limit member is movably connected to one side of the mounting frame, for limiting one direction of the workpiece; along the width direction of the base plate, the second limit member is located on the other side of the mounting frame, for limiting the other direction of the workpiece, the length direction of the base plate is perpendicular to the width direction of the base plate.

[0004] The above technology uses installation frames of different sizes to match workpieces of different external dimensions, but it can only be used separately for specific special-shaped workpieces. In order to adapt to workpieces of different specifications and sizes, it is necessary to use limiters of different lengths. This requires the preparation of multiple sets of fixtures for replacement and matching in actual processing, which greatly reduces the practicality and operating efficiency of the production process. In addition, the fixture system cannot adjust the angle of the workpiece's processed surface, which further limits the applicability of the fixture in processing tasks that require precise angle control, making it difficult to achieve higher standards in production efficiency and processing quality. Summary of the invention

[0005] The present invention proposes an angle-adjustable milling machine fixture to ensure that different angles of a workpiece can be effectively processed, thereby improving the processing applicability of the equipment and improving the accuracy and convenience of the processing process, making the equipment not only more flexible and efficient, but also greatly enhancing the workers' operating experience and production efficiency.

[0006] The technical solution of the present invention is as follows: An angle-adjustable milling machine fixture includes a machining center; A positioning fixture is detachably fixedly connected in the machining center, and the positioning fixture includes: Two limit seats, both of which are detachably fixedly connected to the workbench in the machining center; Two working plates, the two working plates are respectively connected to adjacent limiting seats, and a limiting seat is slidably connected between the two working plates; Two limiting plates, each of which is rotatably connected to a side of a limiting seat facing an adjacent working plate, and each of which is connected with a limiting assembly for quickly limiting the working plate on the adjacent side; The electric control module is fixedly connected to the workbench in the machining center, and the electric control module abuts against the limit seat on one side to rotate the limit disk on the side.

[0007] Further, the limit assembly includes a limit plate, which is coaxially arranged in the limit plate and rotatably connected to the limit plate, and a linkage plate is fixedly connected to the side of the limit plate away from the adjacent limit seat, and two linkage plates are hinged on the linkage plate, and each linkage plate is hinged with a receiving plate, and one end of each receiving plate away from the linkage plate is slidably abutted against the outer side surface of the limit plate; One end of each receiving plate away from the linkage plate is fixedly connected with a clamping block, and the working plate is clamped between two adjacent clamping blocks; A first gear is fixedly connected to a side of the limiting plate facing the adjacent limiting seat, and a plurality of second gears are rotatably connected to the limiting plate, and each of the second gears is meshed with the first gear.

[0008] Furthermore, each of the second gears is fixedly connected with a first screw.

[0009] Furthermore, two limiting grooves are provided on the limiting plate on one side facing the locking block, and one end of each receiving plate away from the linkage plate abuts against the inner wall of the adjacent limiting groove.

[0010] Furthermore, each of the positioning blocks is provided with two symmetrically arranged positioning grooves, each of the positioning grooves is abutted with a positioning block, a connecting plate is slidably connected between the two positioning blocks on the same side, a second screw is threadedly connected to the connecting plate, a pressure plate is rotatably connected to the second screw, and the pressure plate abuts against the inner side surface of the connecting plate.

[0011] Furthermore, a positioning groove is formed on the positioning block, and the outer side surface of each positioning block abuts against the inner wall of the adjacent positioning groove.

[0012] Furthermore, each of the working plates is detachably fixedly connected with a card removal plate, the card removal plate has a gradually enlarged trapezoidal shape on the side away from the working plate, the positioning block has an inclined groove on the side facing the card removal plate, and the card removal plate abuts against the inclined grooves on both sides.

[0013] The beneficial effects of the present invention are: Through the electronic control module, the servo motor can accurately control the limiting disk at one end. Using this technology, workers can more accurately adjust the flip angle of the workpiece to ensure that different angles of the workpiece can be effectively processed, thereby improving the processing applicability of the equipment. In addition, the distance between the two working plates can be adjusted as needed to adapt to the processing of workpieces of different lengths or multiple workpieces, further improving the applicability and efficiency of the equipment. In order to more accurately control the distance between the two working plates, the preferred solution is to install a double-headed cylinder on the back of the limiting seat. The addition of the double-headed cylinder makes the workpiece more convenient when installing and removing. When the workpiece is processed, the worker only needs to loosen the connecting nut between the workpiece and the workplate and start the double-headed cylinder to easily remove the workpiece from the workplate; in addition, the worker can also accurately control the installation position of the workpiece by adjusting the stroke of the double-headed cylinder, so as to facilitate the observation of the processing of the workpiece. Then, combined with the limit assembly, the workplate with the workpiece installed can be quickly positioned and clamped, reducing the labor intensity of the workers and improving the operating efficiency.

DETAILED DESCRIPTION

[0017] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1 to Figure 8 As shown, this embodiment proposes an angle-adjustable milling machine fixture, including a machining center 10; The clamping fixture 11 is detachably fixedly connected to the machining center 10, and the clamping fixture 11 can be connected to the machining center 10 by a connection relationship between bolts and nuts; The clamping fixture 11 includes: Two limit seats 12, both of which are detachably fixedly connected to the workbench in the machining center 10; Two working plates 13, the two working plates 13 are respectively connected to adjacent limiting seats 12, and the limiting seat 14 is slidably connected between the two working plates 13; Two limiting plates 15, each limiting plate 15 is rotatably connected to the limiting seat 12 facing the adjacent working plate 13, and a limiting component for quickly limiting the adjacent working plate 13 is connected inside the limiting plate 15; The limit assembly plays a role of rapid positioning and clamping, so that the working plate 13 with the workpiece installed can be quickly positioned and clamped, reducing the labor intensity of the workers; The electric control module 16 is fixedly connected to the workbench in the machining center 10, and the electric control module 16 abuts against the limiting seat 12 on one side, and is used to rotate the limiting disk 15 on the side; Through the electronic control module 16, the servo motor can accurately control the limiting disk 15 at one end. Using this technology, workers can more accurately adjust the flip angle of the workpiece to ensure that different angles of the workpiece can be effectively processed, thereby improving the processing applicability of the equipment. In addition, the distance between the two working plates 13 can be adjusted as needed to adapt to the processing of different lengths or multiple workpieces, further improving the applicability and efficiency of the equipment. In order to more accurately control the distance between the two working plates 13, the preferred solution is to install a double-headed cylinder on the back of the limiting seat 14. The addition of the double-headed cylinder makes the workpiece more convenient when installing and removing. When the workpiece is processed, the worker only needs to loosen the connecting nut between the workpiece and the working plate 13 and start the double-headed cylinder to easily remove the workpiece from the working plate 13. In addition, the worker can also accurately control the installation position of the workpiece by adjusting the stroke of the double-headed cylinder, so as to facilitate the observation of the processing of the workpiece. Then, combined with the limit assembly, the workplate 13 with the workpiece installed can be quickly positioned and clamped, reducing the labor intensity of the workers and improving the operating efficiency. The overall design improves the accuracy and convenience of the processing process, making the equipment not only more flexible and efficient, but also greatly enhancing the workers' operating experience and production efficiency.

[0020] like Figure 2~Figure 6 As shown, the limit assembly includes a limit plate 21, which is coaxially arranged in the limit plate 15 and rotatably connected to the limit plate 15. The side of the limit plate 21 away from the adjacent limit seat 12 is fixedly connected to the linkage plate 22, and two linkage plates 23 are hinged on the linkage plate 22. Each linkage plate 23 is hinged to each receiving plate 24, and one end of each receiving plate 24 away from the linkage plate 23 is slidably abutted against the outer side surface of the limit plate 15; One end of each receiving plate 24 away from the linkage plate 23 is fixedly connected to each clamping block 25, and the working plate 13 is clamped between two adjacent clamping blocks 25; The limiting plate 21 is fixedly connected to the first gear 26 on the side facing the adjacent limiting seat 12, and a plurality of second gears 27 are rotatably connected to the limiting plate 15, and each second gear 27 is meshed with the first gear 26; By driving the first gear 26 through a plurality of second gears 27, workers can apply forces from different angles, flexibly adjust the operation, and improve convenience. Only by rotating the first gear 26, the working plate 13 can be quickly limited to achieve rapid positioning and clamping. This design significantly reduces the labor intensity of workers, makes the operation more efficient, and improves the accuracy and convenience of the processing process.

[0021] like Figure 3~Figure 4 As shown, two limiting grooves 151 are provided on the side of the limiting plate 15 facing the positioning block 25, and one end of each receiving plate 24 away from the linkage plate 23 abuts against the inner wall of the adjacent limiting groove 151; Through the limiting effect of the limiting groove 151, when the linkage disk 22 rotates, the two clamping blocks 25 will be driven to move synchronously and stably. The limiting groove 151 ensures the precise trajectory of the clamping block 25, so that it always maintains a consistent movement path during the rotation process. This design effectively improves the center accuracy of the two clamping blocks 25 when clamping the working plate 13, ensures the accurate positioning of the working plate 13 during the clamping process, and thus improves the overall clamping stability and accuracy.

[0022] like Figure 2 and Figure 5 As shown, two symmetrically arranged positioning grooves 251 are provided on the positioning block 25, each positioning block 31 abuts against each positioning groove 251, a connecting plate 32 is slidably connected between two positioning blocks 31 on the same side, a second screw 33 is threadedly connected to the connecting plate 32, a pressure plate 34 is rotatably connected to the second screw 33, and the pressure plate 34 abuts against the inner side surface of the connecting plate 32; When the two positioning blocks 25 move toward each other and clamp the working plate 13, the two positioning blocks 31 are connected by the connecting plate 32 and move along the positioning groove 251. This linkage design allows the connecting plates 32 on both sides to move toward the working plate 13 at the same time, thereby limiting the degree of freedom of the working plate 13 through interaction and further improving its positioning accuracy. Through this linkage mechanism, the working plate 13 can obtain more precise limit during the clamping process, ensuring that the clamping force is evenly distributed, improving the stability and accuracy of the overall system, and then the design of the second screw 33 is suitable for use with working plates 13 of different thicknesses, improving usability.

[0023] like Figure 2 and Figure 5~Figure 6 As shown, the positioning groove 252 is formed on the positioning block 25, and the outer side surface of each positioning block 31 abuts against the inner wall of the adjacent positioning groove 252; The outer side of the positioning block 31 abuts against the inner wall of the adjacent positioning groove 252, which can effectively limit the sliding of the positioning block 31 on the positioning block 25, thereby ensuring that the sliding process is more stable. This design improves positioning accuracy, reduces unnecessary displacement, and enhances the stability of the overall structure.

[0024] Example 2

[0025] This example improves the working plate 13 on the basis of Example 1; like Figure 7~Figure 8 As shown, each card and unloading plate 35 is detachably fixedly connected to each working plate 13, and the card and unloading plate 35 is in a gradually enlarged trapezoidal shape on the side away from the working plate 13, and the card block 25 is in an inclined groove 253 on the side facing the card and unloading plate 35, and the card and unloading plate 35 abuts against the inclined grooves 253 on both sides; In the clamp, the contact and clamping parts are usually the most severely worn. In order to solve this problem, a card removal plate 35 is added to the design to transfer the wear to the card removal plate 35. In this way, in the subsequent use process, only the card removal plate 35 needs to be replaced without replacing other parts, thereby reducing the replacement cost of equipment parts. At the same time, the appearance design of the card removal plate 35 also plays a key role. When the two card blocks 25 are squeezed against each other, the card removal plate 35 will move along the inner wall of the inclined groove 253 toward the limiting disk 15, thereby prompting each working plate 13 to be more tightly clamped with the adjacent card blocks 25, making the working plate 13 more stable after installation, further improving the clamping strength and the overall reliability of the system.

[0026] Example 3

[0027] This example improves the second gear 27 on the basis of Example 1; like Figure 3~Figure 4 As shown, each first screw 271 is fixedly connected to each second gear 27; By installing the first screw 271 to drive the second gear 27, the second gear 27 can be rotated more easily. At the same time, the thread limiting function of the first screw 271 itself ensures that the second gear 27 will not easily deviate during the rotation process. In this way, the rotation path of the second gear 27 is effectively constrained, thereby improving its rotation accuracy. This design not only enhances the driving stability, but also ensures the precise transmission of the gear system and improves the reliability of the overall mechanical structure.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
