Description
Technical Field
[0001] This utility model relates to the field of screw processing technology, specifically a separation pressure plate for screw processing. Background Technology
[0002] In the screw manufacturing industry chain, the separation pressure plate is a core tooling component for screw cutting, tapping, heat treatment and other processes. It is mainly used to position, clamp and separate batches of screw blanks or semi-finished products to ensure the stability of the screws during processing and to achieve orderly discharge of finished products after processing. It is widely used in automated screw production lines, precision hardware processing workshops and other scenarios.
[0003] Currently, screw separation plates in batch processing often rely on manual operation or independent drive mechanisms for screw separation and unloading. Manual operation requires releasing the clamping components one by one after processing, which is inefficient. While independent drive unloading mechanisms can improve efficiency, they require additional components such as motors and cylinders, and the separation action needs to be triggered separately after processing, which not only increases equipment costs and the risk of failure, but also requires complex mechanical adjustments to match the processing rhythm. Therefore, a new technical solution is proposed to address this issue. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a separation pressure plate for screw processing. This solves the technical problem that current screw processing separation pressure plates rely on manual labor or independent drive mechanisms to achieve screw separation and unloading in batch processing scenarios. Although some independent drive unloading mechanisms can improve efficiency, they require additional components such as motors and cylinders. After processing, the separation action needs to be triggered separately, which increases equipment costs and failure risks.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a separation pressure plate for screw processing is designed, including a separation pressure plate body and a positioning frame. The surface of the separation pressure plate body is provided with a main limiting groove, and the top edge of the separation pressure plate body is provided with a secondary limiting groove. The main limiting groove and the secondary limiting groove are connected. The front and rear inner sidewalls of the positioning frame are provided with sliding grooves, and a first clamping block and a second clamping block are slidably connected between the front and rear sliding grooves. The bottom of the first clamping block is fixedly connected with a bottom post, and the bottom of the bottom post is located inside the main limiting groove and the secondary limiting groove.
[0006] In this design, the bottom column is constrained by the main limiting groove, causing clamping blocks one and two to tightly clamp the screw, ensuring stable processing posture. After processing, the servo motor drives the rotating block to rotate the positioning frame. When the bottom column moves with the positioning frame to the secondary limiting groove, the limiting constraint is released, clamping block one automatically resets and releases the screw, which slides down the secondary limiting groove to the discharge port to complete automatic discharge. The entire process requires no manual release of the clamps and no additional separation drive components. The separation action is integrated synchronously with the rotation of the positioning frame, significantly improving separation efficiency and reducing manual intervention costs and production downtime.
[0007] Preferably, a rotating block is rotatably connected to the top center of the separating pressure plate body, and several connecting arms are fixedly connected to the outer side wall of the rotating block in a circular array, and the outer ends of the connecting arms are fixedly connected to the positioning frame.
[0008] In practical applications, the rotating block rotates, and through the connecting arm, it drives each positioning frame to pass through the processing, unloading, and upper and lower areas in sequence, thereby realizing cyclic operation and improving processing efficiency.
[0009] Preferably, a slide rail is fixedly connected to the top end of the connecting arm, a slider is slidably connected to the surface of the slide rail, a push-pull rod is fixedly connected between the slider and the second clamping block, and the push-pull rod passes through the side wall of the positioning frame and is slidably connected to the positioning frame.
[0010] In practical applications, the slider moves laterally along the slide rail. During the movement, the push-pull rod drives the second clamping block to move laterally, thereby changing the initial distance between it and the first clamping block, adapting to the processing of screws of different sizes and improving adaptability.
[0011] Preferably, two limiting rods are fixedly connected to the top of the rotating block. Both limiting rods pass through the lifting plate and are slidably connected to the lifting plate. An inclined arm is provided between the lifting plate and each slider. The two ends of the inclined arm are rotatably connected to the lifting plate and the slider respectively through hinge seats.
[0012] In practical applications, as the lifting plate slides along the limit rod, the two ends of the inclined arm rotate to push the slider. Multiple slider positions can be adjusted simultaneously to ensure consistent spacing between the positioning frame clamps, improving the uniformity of multi-station processing and reducing debugging time.
[0013] Preferably, a threaded sleeve is fixedly connected to the top surface of the rotating block between the two limiting rods, and a stud is threadedly connected to the inner side of the threaded sleeve. The stud penetrates the surface of the lifting plate and is threadedly connected to the lifting plate.
[0014] In practical applications, rotating the stud causes it to rotate within the threaded sleeve, which in turn moves the lifting plate. The threaded connection has self-locking properties, allowing the lifting plate to remain stably in the target position, ensuring a fixed spacing between the clamping blocks, preventing loosening during processing, and improving clamping stability.
[0015] Preferably, a servo motor is fixedly connected to the center of the bottom of the separation pressure plate body, and the tail end of the drive shaft of the servo motor is connected to the rotating block through a coupling.
[0016] In practical applications, the servo motor starts, and the drive shaft drives the rotating block to rotate via a coupling. The rotation speed and angle of the rotating block can be precisely controlled, allowing the positioning frame to stop precisely at processing, loading, and other workstations, realizing automated cyclic operation and improving processing efficiency.
[0017] Preferably, the surface of the separation pressure plate body near the secondary limiting groove is provided with a discharge port, and the surface of the limiting rod is provided with scale lines.
[0018] In practical applications, the screw slides from the secondary limit groove to the discharge port and is discharged without manual removal; the scale lines on the limit rod can intuitively display the position of the lifting plate, assist in the precise adjustment of the clamping block spacing, adapt to screws of different sizes, and improve the ease of operation.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a main limiting groove and a secondary limiting groove on the surface of the separating pressure plate body. During processing, the bottom column is constrained by the main limiting groove, causing clamping blocks one and two to tightly clamp the screw, ensuring stable processing posture. After processing, the servo motor drives the rotating block to rotate the positioning frame. When the bottom column moves with the positioning frame to the secondary limiting groove, the limiting constraint is released, clamping block one automatically resets and releases the screw, and the screw slides down the secondary limiting groove to the discharge port to complete automatic discharge. The entire process requires no manual release of the clamps and no additional separation drive components. By integrating the separation action with the rotation of the positioning frame synchronously, separation efficiency is greatly improved, and manual intervention costs and production downtime are reduced.
[0020] 2. This utility model features a lifting plate at the top of a rotating rod, with its lifting controlled by a stud. The lifting plate pushes a slider along a slide rail via a slanted arm. The slider then moves a second clamping block along a positioning frame groove via a push-pull rod, thereby adjusting the distance between the first and second clamping blocks. Simultaneously, the scale lines on the limit rod surface visually indicate the position of the lifting plate, aiding in precise control of the clamping block distance. This ensures stable clamping of screws of different diameters and lengths, eliminating the need to replace the entire pressure plate assembly. This significantly improves the device's versatility and reduces the changeover costs and time associated with processing multi-specification screws. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A separating pressure plate for screw processing, see [link to example]. Figures 1 to 4 The system includes a separating pressure plate body 1 and a positioning frame 5. The surface of the separating pressure plate body 1 is provided with a main limiting groove 101, and the top edge of the separating pressure plate body 1 is provided with a secondary limiting groove 102. The main limiting groove 101 and the secondary limiting groove 102 are connected. The front and rear inner walls of the positioning frame 5 are provided with sliding grooves 501, and a first clamping block 6 and a second clamping block 7 are slidably connected between the front and rear sliding grooves 501. The inner walls of the two clamping blocks are provided with anti-slip pads to increase friction and improve stability. The bottom of the first clamping block 6 is fixedly connected with a bottom column 601. The bottom of the bottom column 601 is located inside the main limiting groove 101 and the secondary limiting groove 102. The surface of the separating pressure plate body 1 near the secondary limiting groove 102 is provided with a discharge port 103.
[0023] In the above technical solution, the screw blank is placed between clamping block 6 and clamping block 7 within the positioning frame 5. The bottom post 601 of clamping block 6 enters the main limiting groove 101, clamping the screw. After the screw is processed, the positioning frame 5 moves the bottom post 601 from the main limiting groove 101 to the secondary limiting groove 102. The secondary limiting groove 102 has a larger lateral space, releasing the constraint on the bottom post 601. Clamping block 6 can then naturally reset and separate from clamping block 7. Under gravity, the screw slides down the secondary limiting groove 102 to the discharge port 103 for discharge. The entire process requires no manual release of the clamps and no additional separation drive components. The separation action is integrated synchronously with the rotation of the positioning frame 5, significantly improving separation efficiency and reducing manual intervention costs and production downtime.
[0024] It is worth noting that the screw processing machine can be fixed on the left side of the separating pressure plate body 1, so that the processing head of the processing machine is precisely aligned with the positioning frame 5 on the left side above the main limiting groove 101; at the same time, the screw feeding machine is set on the side of the separating pressure plate body 1 near the discharge port 103, and the discharge end of the feeding machine is aligned with the positioning frame 5 that has just finished discharging and has not yet rotated with the connecting arm 4 to the position above the main limiting groove 101. At this time, the positioning frame 5 is not fully clamped because the bottom column 601 is still inside the secondary limiting groove 102, and the first clamping block 6 and the second clamping block 7 are still separated, which facilitates feeding.
[0025] Specifically, such as Figure 1 and Figure 2 As shown, a rotating block 3 is rotatably connected to the top center of the separating pressure plate body 1. Several connecting arms 4 are fixedly connected to the outer side wall of the rotating block 3 in a circular array, and the outer ends of the connecting arms 4 are fixedly connected to the positioning frame 5. A servo motor 2 is fixedly connected to the bottom center of the separating pressure plate body 1. The tail end of the drive shaft of the servo motor 2 is connected to the rotating block 3 through a coupling.
[0026] In the above technical solution, the servo motor 2 is started, and its transmission shaft drives the rotating block 3 to rotate around the central axis of the separation pressure plate body 1 through the coupling. When the rotating block 3 rotates, it drives multiple positioning frames 5 to perform circular motion synchronously through the connecting arms 4 of the circular array. When one of the positioning frames 5 rotates to the processing station with the connecting arm 4, the servo motor 2 stops precisely, allowing the processing machine to process the screw in the current positioning frame 5. During the rotation, each positioning frame 5 completes operations such as feeding and separating to achieve continuous operation.
[0027] Furthermore, a slide rail 401 is fixedly connected to the top of the connecting arm 4, and a slider 9 is slidably connected to the surface of the slide rail 401. A push-pull rod 8 is fixedly connected between the slider 9 and the second clamping block 7. The push-pull rod 8 passes through the side wall of the positioning frame 5 and is slidably connected to the positioning frame 5. Two limiting rods 12 are fixedly connected to the top of the rotating block 3. The surface of the limiting rod 12 is provided with scale lines 121. Both limiting rods 12 pass through the lifting plate 11 and are slidably connected to the lifting plate 11. An inclined arm 10 is provided between the lifting plate 11 and each slider 9. The two ends of the inclined arm 10 are rotatably connected to the lifting plate 11 and the slider 9 respectively through hinge seats.
[0028] In the above technical solution, when it is necessary to adjust the distance between clamping block 6 and clamping block 7 to accommodate screws of different sizes, the lifting plate 11 is pushed to slide up and down along the limiting rod 12. When the lifting plate 11 moves, one end of the inclined arm 10 moves synchronously through the hinge seat, and the other end of the inclined arm 10 pushes the slider 9 to slide along the slide rail 401. When the slider 9 slides, the second clamping block 7 moves along the slide groove 501 of the positioning frame 5 through the push-pull rod 8, thereby changing the initial distance between the second clamping block 7 and the first clamping block 6, ensuring that screws of different diameters and lengths can be stably clamped without replacing the entire pressure plate assembly, significantly improving the versatility of the device and reducing the changeover cost and time for processing multi-specification screws.
[0029] It is worth noting that, such as Figure 2 As shown, a threaded sleeve 13 is fixedly connected to the top surface of the rotating block 3 between the two limiting rods 12. A stud 14 is threadedly connected to the inner side of the threaded sleeve 13. The stud 14 penetrates the surface of the lifting plate 11 and is threadedly connected to the lifting plate 11. Rotating the stud 14 causes the lifting plate 11 to move up and down along the limiting rods 12. For example, when the stud 14 is rotated clockwise, the lifting plate 11 moves closer to the rotating block 3, and through the inclined arm 10, the slider 9 and the push-pull rod 8, it causes the second clamping block 7 to move closer to the first clamping block 6, reducing the clamping block spacing. When the stud 14 is rotated counterclockwise, the lifting plate 11 moves away from the rotating block 3, causing the second clamping block 7 to move away from the first clamping block 6, increasing the clamping block spacing. The self-locking property of the threaded connection allows the lifting plate 11 to stay stably at the target position, ensuring that the clamping block spacing is fixed.
