Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a precision positioning device for a high-speed punch press. Background Technology

[0002] High-speed punch presses are precision equipment capable of continuous stamping at a frequency of hundreds to thousands per minute. They are widely used in the mass production of thin sheet metal parts in industries such as electronics and automobiles. Their core advantages lie in high stamping efficiency and stable precision. By strengthening the rigidity of the machine body and the servo control system, they can quickly complete the blanking, forming and other processes of complex parts.

[0003] When processing workpieces with a high-speed punch press, a precise positioning device is needed to counteract the vibration and inertia of high-speed punching, ensuring that the positional deviation of the workpiece is controlled within the micrometer level for each punching. Its processing efficiency can reach hundreds to thousands of times per minute, and it can quickly complete the continuous punching, bending or forming of workpieces, making it suitable for mass production.

[0004] When processing workpieces using a high-speed punch press, the workpiece is usually placed into the corresponding placement hole for restriction. However, the placement hole is usually larger than the workpiece to facilitate the placement and removal of the workpiece. However, different sizes will affect the effect of the workpiece after punching.

[0005] Therefore, a precision positioning device for high-speed punch presses is proposed to address the above problems. Utility Model Content

[0011] Preferably, the top of the skateboard is slidably fitted with a cover; the cover is located above the square plate; by adding the cover, the skateboard can be closed, reducing dust from entering the groove through the space between the square plate and the skateboard, thereby protecting the second spring.

[0012] Preferably, a pull rope is fixedly connected to the end of the cover; the end of the pull rope and the slide plate are fixedly connected; by adding the pull rope, the range of motion of the cover can be restricted when it is placed, thereby increasing the restraint on it.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a precision positioning device for a high-speed punch press includes a base 1, a worktable 11 fixedly connected to the top of the base 1; a high-speed punch press body 12 fixedly connected to the top of the worktable 11; a cylinder 13 fixedly connected to the top of the high-speed punch press body 12; a punching assembly 14 fixedly connected to the output end of the cylinder 13; a punching head 15 fixedly connected to the bottom of the punching assembly 14; a push rod 16 fixedly connected to the end of the punching assembly 14; a punching table 17 fixedly connected to the middle of the worktable 11; a sliding plate 18 slidably connected to the surface of the punching table 17; a linkage plate 19 fixedly connected to the end of the sliding plate 18; the surfaces of the push rod 16 and the linkage plate 19 are both inclined and are opposite to each other. The following configuration is provided: a first spring 101 is fixedly connected to the bottom of the slide plate 18; the end of the first spring 101 and the stamping table 17 are fixedly connected; an installation component 102 is provided at the end of the slide plate 18; a positioning plate 103 is fixedly connected to the end of the installation component 102; a limit plate 104 is fixedly connected to the middle of the stamping table 17; the limit plate 104 and the positioning plate 103 are correspondingly configured; during operation, when processing the workpiece, the workpiece is first placed below the stamping head 15, and then the cylinder 13 drives the stamping component 14 to move downward. During the downward movement, the stamping head 15 is pushed and moved towards the workpiece, and the push rod 16 also moves downward. During the downward movement, it will contact the linkage plate 19, and then move along... As the linkage plate 19 moves, it gradually pushes the slide plate 18 forward. During this movement, the slide plate 18 moves the positioning plate 103 closer to the workpiece. During the movement of the slide plate 18, the first spring 101 is compressed. Upon contact with the workpiece, it moves the workpiece closer to the limiting plate 104. When the workpiece contacts the limiting plate 104, the punch head 15 also simultaneously contacts the workpiece. The punch head 15 then punches the workpiece. As the punch head 15 moves downward, the push rod 16 and the linkage plate 19 work together to push the slide plate 18 to the positioning plate 103, moving the workpiece to the designated position where it is punched by the punch head 15. After the punching is completed, the push rod 16 gradually moves away from the linkage plate 19, and the first spring 101... Spring 101 will rebound, pushing the linkage plate 19, thereby disengaging the positioning plate 103 from contact with the workpiece. At this point, it can be removed and replaced. After the positioning plate 103 has been in use for a long time, it can be disassembled and repaired through the mounting assembly 102. By using the cooperation of push rod 16 and linkage plate 19, the workpiece can be quickly guided to the cooperation position with the punch head 15 through the pushing of positioning plate 103 and limit plate 104, which increases the punching effect of the punch head 15. The cooperation of push rod 16 and linkage plate 19 moves the workpiece quickly and then fixes it, positioning it in the designated punching position, thereby increasing the positional accuracy of the punch head 15.

[0026] like Figures 3 to 5As shown, the mounting assembly 102 includes a locking block 2; the locking block 2 and the positioning plate 103 are fixedly connected; the sliding plate 18 has a sliding groove 21 inside; the sliding groove 21 and the locking block 2 are in sliding engagement; a plug rod 22 is slidably connected inside the sliding plate 18; a second spring 23 is fixedly connected between the plug rod 22 and the sliding plate 18; a slot 24 is opened inside the locking block 2; the second spring 23 and the slot 24 are correspondingly arranged and in sliding engagement; the end of the plug rod 22 is arc-shaped; a square plate 25 is fixedly connected to the top of the plug rod 22; during operation, when it is necessary to disassemble the positioning plate 103, the square plate 25 can be clamped, and then the square plate 25 can be pulled to move the plug rod 22 upward. When the plug rod 22 moves upward, it will compress the second spring 23, and then the plug rod 22 will gradually leave the slot 24. After 4, the locking block 2 will be unlocked, and then the locking block 2 can be slid to disengage it from the slide groove 21, allowing the positioning plate 103 to be removed. After maintenance, the locking block 2 can be inserted back into the slide groove 21. When the end of the locking block 2 contacts the insertion rod 22 during movement, the insertion rod 22 will move along the surface of the locking block 2 and then move upward. When the insertion rod 22 moves on the locking block 2, it will contact the slot 24, and then the pressure of the second spring 23 will push the insertion rod 22 into the slot 24, thereby engaging and installing. By using the insertion rod 22 and the slot 24 to fix the locking block 2, disassembly can be faster, reducing operation time. At the same time, during installation, the elasticity of the insertion rod 22 can move the insertion rod 22, reducing the operation of the opposite plate 25, allowing it to be quickly fixed upon insertion.

[0027] like Figure 2 As shown, rollers 3 are rotatably connected to the surface of the linkage plate 19; multiple rollers 3 are arranged on the linkage plate 19; during operation, when the push rod 16 contacts the linkage plate 19, it will contact the rollers 3, and then when the push rod 16 moves, it will contact the rollers 3 again. When in contact, the rollers 3 will rotate, which will reduce the friction of the push rod 16 on the linkage plate 19, thus accelerating the push of the slide plate 18; by adding rollers 3, the friction of the push rod 16 on the linkage plate 19 can be reduced by the rolling of the rollers 3 when the push rod 16 contacts the linkage plate 19, thereby accelerating the moving speed of the push rod 16.

[0028] like Figure 2 As shown, a flexible pad 4 is fixed to the inner wall of the limiting plate 104; the flexible pad 4 and the limiting plate 104 are correspondingly arranged; during operation, when the workpiece is pushed by the positioning plate 103 and comes into contact with the limiting plate 104, it will first come into contact with the flexible pad 4. During the contact, the flexible pad 4 will block the workpiece with its own flexibility, reducing the impact when the workpiece is pushed by the positioning plate 103 and comes into contact with the limiting plate 104; by adding the flexible pad 4, protection can be added after the positioning plate 103 pushes the workpiece, so as to reduce the damage after the push.

[0029] like Figure 5 As shown, the top of the slide plate 18 is slidably fitted with a cover 5; the cover 5 is located above the square plate 25; during operation, after the square plate 25 is used, the cover 5 can be placed on top of the slide plate 18, and then the middle part can be pressed down to make it enter the interior of the slide plate 18, thereby closing the top of the square plate 25 and reducing the amount of dust entering the interior of the slide plate 18 during processing; by adding the cover 5, the slide plate 18 can be closed, reducing the amount of dust entering the slide groove 21 through the space between the square plate 25 and the slide plate 18, thereby protecting the second spring 23.

[0030] like Figure 5 As shown, a pull rope 6 is fixedly connected to the end of the cover 5; the end of the pull rope 6 is fixedly connected to the slide plate 18; during operation, when the cover 5 is removed, it will be restrained by the pull rope 6, preventing it from falling to the surroundings, thereby increasing the restriction in subsequent use; by adding the pull rope 6, the range of motion of the cover 5 can be restricted when it is placed, thereby increasing the restraint on it.

[0031] Working principle: When processing a workpiece, the workpiece is first placed below the stamping head 15. Then, the cylinder 13 drives the stamping assembly 14 to move downwards. During this downward movement, the stamping head 15 is pushed towards the workpiece, and the push rod 16 also moves downwards. During this downward movement, it comes into contact with the linkage plate 19 and then moves along the surface of the linkage plate 19. During this movement, it gradually pushes the slide plate 18 forward. As it moves, the slide plate 18 drives the positioning plate 103 to move closer to the workpiece. During the movement of the slide plate 18, the first spring 101 is compressed. Then, when it comes into contact with the workpiece, it drives the workpiece to move closer to the limiting plate 104. When the workpiece contacts the limiting plate 104, the stamping head 15 also contacts the workpiece simultaneously. Then, the stamping head 15 stamps the workpiece. During the downward movement of the stamping head 15, the push rod 16 and the linkage plate 19 work together to push the slide plate 18 to the positioning plate 103, so that the workpiece is moved to the designated position and stamped by the stamping head 15. After the stamping is completed, when the push rod 16 gradually moves away from the linkage plate 19, the first spring 101 will rebound, pushing the linkage plate 19, thereby separating the positioning plate 103 from the workpiece. At this time, it can be removed and replaced. After the positioning plate 103 has been working for a long time, it can be disassembled and repaired through the mounting assembly 102. When it is necessary to disassemble the positioning plate 103, the square plate 25 can be clamped, and then the square plate 25 can be pulled to move the insert rod 22 upward. When the insert rod 22 moves upward, it will compress the second spring 23, and then the insert rod 22 will gradually move upward. After leaving the slot 24, the locking block 2 will be unlocked. The locking block 2 can then be slid to disengage from the slide groove 21, allowing the positioning plate 103 to be removed. After maintenance, the locking block 2 can be reinserted into the slide groove 21. When the end of the locking block 2 contacts the insertion rod 22 during movement, the insertion rod 22 will move along the surface of the locking block 2 and then move upwards. As the insertion rod 22 moves on the locking block 2, it will contact the slot 24. The pressure of the second spring 23 will then push the insertion rod 22 into the slot 24, thus achieving locking and installation. When the push rod 16 contacts the linkage plate 19, it will contact the roller 3. Subsequently, as the push rod 16 moves, it will contact the roller 3 again, causing the roller 3 to rotate. When rotating, it reduces the friction of the push rod 16 on the linkage plate 19, thus accelerating the push of the slide plate 18. When the workpiece is pushed by the positioning plate 103 and contacts the limiting plate 104, it will first contact the flexible pad 4. During the contact, the flexible pad 4 will block the workpiece with its own flexibility, reducing the impact when the workpiece is pushed by the positioning plate 103 and contacts the limiting plate 104. After daily use of the square plate 25, the cover 5 can be placed on top of the slide plate 18, and then the middle part can be pressed to make it enter the interior of the slide plate 18. This can close the top of the square plate 25, reducing the amount of dust entering the interior of the slide plate 18 during processing. When the cover 5 is removed, it will be restrained by the pull rope 6, preventing it from falling to the surroundings, thus increasing the restriction in subsequent use.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
