Description

Technical Field

[0001] This utility model belongs to the field of processing equipment technology, and specifically relates to a rapid positioning mechanism. Background Technology

[0002] In equipment design, component positioning and clamping are necessary during component placement. This ensures accuracy and component stability. Positioning and clamping guarantee accurate component placement, preventing quality issues caused by positional deviations. Typically, component positioning uses three fixed sides and one movable side for easy component insertion and removal. For example, a movable side with a bottom opening requires high precision in component insertion and removal due to its left-right fixation, impacting positioning and clamping efficiency. Alternatively, a combination of horizontal and vertical movable clamping is used. This requires a drive and clamping component in each direction, working together to control component positioning and clamping. Limiting and detection devices are also needed to ensure consistent component position during clamping. Even combining these methods still requires multiple mechanisms or devices for auxiliary positioning and clamping, hindering rapid positioning and increasing complexity and cost. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the background technology mentioned above, and to provide a quick positioning mechanism that uses longitudinal movement to drive lateral movement to unfold together, and then uses a return spring to automatically reset both to position and clamp the workpiece, simplifying the structure, facilitating the removal or placement of workpieces, and improving processing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rapid positioning mechanism, comprising a positioning disk, a rotating disk disposed below the positioning disk, a set of positioning cylinders mounted on the positioning disk, and a set of positioning carriers mounted on the rotating disk. The positioning cylinders are aligned with the positioning carriers. The positioning carriers include a base plate, a positioning push plate, a positioning platform, a movable baffle, and a pair of movable claws. The base plate is mounted on the rotating disk. The positioning platform is fixed above the base plate by a connecting column. A slide rail is installed in the middle of the base plate. The positioning push plate is located between the base plate and the positioning platform and is slidably connected to the slide rail. The end of the positioning platform away from the positioning cylinders is vertically connected to the movable baffle. The end of the top surface of the positioning push plate away from the positioning cylinders and the bottom surface of the positioning platform are connected... Each end near the positioning cylinder is connected with a connecting bolt, and a spring is installed between two connecting bolts. The movable claw includes a sliding plate, a support plate, rollers, grippers, and springs. A groove perpendicular to the slide rail is opened in the middle of the top of the base plate. The sliding plate is slidably connected to the groove. The support plate is vertically installed on the outer end face of the sliding plate. Grippers are horizontally installed on the top surface of the support plate. Connecting bolts are installed on the support plate and the base plate. The two ends of the spring are fixedly connected to the support plate and the base plate, respectively. A roller is rotatably connected to the top surface of the support plate near the slide rail. Inclined blocking frames are also provided on both sides of the positioning push plate at the corresponding position. When the blocking frames move, they will drive the rolling rotation and simultaneously squeeze the rollers to move to both sides. When the positioning cylinder extends, it will drive the positioning push plate to move.

[0005] Furthermore, the positioning cylinder includes a mounting base, a linear cylinder, a push block, and a slide rail. The mounting base is fixed to the positioning plate with bolts, and the linear cylinder and the slide rail are fixed in parallel. The push block has a Z-shaped structure, with its front end fixedly connected to the linear cylinder and its bottom slidably connected to the slide rail. When the linear cylinder is working, it will drive the push block to move back and forth along the slide rail, so that the front end of the push block presses against the positioning push plate to make it move.

[0006] Furthermore, the positioning platform consists of two load plates, and the positioning platform is also provided with a first fixed baffle and a second fixed baffle. The first fixed baffle is installed on the load plate near the end of the positioning cylinder, and the second fixed baffle is installed on the adjacent side of the load plate, connecting the two load plates into a whole.

[0007] Furthermore, the blocking frame consists of a horizontal bar and a diagonal bar. The horizontal bar is installed on the end face of the positioning push plate near the positioning cylinder. One end of the diagonal bar is connected to the end face of the horizontal bar, and the other end is fixed in the middle of the positioning push plate, forming a triangular structure that is wider in the front and narrower in the back, and symmetrical from left to right.

[0008] Furthermore, a limit plate is also connected to the side of the positioning platform near the positioning cylinder.

[0009] Furthermore, the positioning disk is also provided with a limit block, which is located at the front end of the push block and is used to limit the stroke of the push block.

[0010] Furthermore, a distance sensor is also provided at the rear end of the pusher block.

[0011] The beneficial effects of this utility model are: 1) This utility model links the movable baffle and the movable claw through the positioning push plate. When the positioning cylinder extends, the push block will squeeze the positioning push plate, and the movable baffle will move backward. The movable claw will be squeezed by the blocking frame and will separate and open to both sides. The rear end and the left and right ends can be opened at the same time by the push of the linear cylinder, which is convenient for putting in or taking out the material. After the linear cylinder is reset, the movable baffle and the movable claw are reset by two springs, which tightens the space on the positioning platform and clamps and positions the material. One drive can control the opening or closing in two directions, which simplifies the clamping structure and improves the processing efficiency. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0022] Example: Figure 1-8 As shown, the quick positioning mechanism of this utility model includes a positioning disk 1, a rotating disk 2 disposed below the positioning disk 1, a set of positioning cylinders 3 mounted on the positioning disk 1, and a set of positioning carriers 4 mounted on the rotating disk 2, wherein the positioning cylinders 3 and the positioning carriers 4 are aligned.

[0023] A rotating disk 2 is concentrically mounted below the positioning disk 1. The rotating disk 2 is driven to rotate by an external motor. The positioning disk 1 is fixed and its diameter is smaller than that of the rotating disk 2. Multiple positioning cylinders 3 are mounted on the circumference of the positioning disk 1. The same number of positioning carriers 4 are also mounted on the circumference of the corresponding rotating disk 2, so that each positioning cylinder 3 is aligned with the positioning carrier 4, which facilitates positioning and clamping of the material.

[0024] The positioning cylinder 3 includes a mounting base 20, a linear cylinder 21, a push block 22, and a slide rail 11. The mounting base 20 is fixed to the positioning plate 1 with bolts, and the linear cylinder 21 and the slide rail 11 are fixed in parallel. The push block 22 has a Z-shaped structure, with its front end fixedly connected to the linear cylinder 21 and its bottom end slidably connected to the slide rail 11. When the linear cylinder 21 is working, it drives the push block 22 to move back and forth along the slide rail 11, causing the front end of the push block 22 to press against the positioning push plate 6 and move it. A limit block 29 is also installed on the positioning plate 1. The limit block 29 is located at the front end of the push block 22 and is used to limit the stroke of the push block 22 to prevent the push block 22 from exceeding the slide rail 11 and failing to reset. It can also limit the forward distance of the push block 22 to prevent the positioning carrier 4 from failing to reset.

[0025] Linear cylinder 21 is connected to an external drive to control push block 22 to move along slide rail 11. A distance sensor 30 is also installed at the rear end of push block 22. The distance sensor 30 is used to detect whether the positioning carrier 4 on the rotating disk 2 is aligned with the positioning cylinder 3. When the positioning carrier 4 is aligned with the positioning cylinder 3, the distance sensor 30 detects the distance change to determine that the alignment is at this time. The controller stops the external motor and the rotating disk 2, and the external drive drives the linear cylinder 21 to extend. At this time, the push block 22 moves outward and squeezes the positioning carrier 4 to facilitate its movement and positioning. When the linear cylinder 21 resets, the positioning carrier 4 resets and positions and clamps the material.

[0026] The positioning carrier 4 includes a base plate 5, a positioning push plate 6, a positioning platform 7, a movable baffle 8, and a pair of movable claws 9. The base plate 5 is mounted on the rotary disk 2. The positioning platform 7 is fixed above the base plate 5 by a connecting column 10. A slide rail 11 is installed in the middle of the base plate 5. The positioning push plate 6 is located between the base plate 5 and the positioning platform 7 and is slidably connected to the slide rail 11. The end of the positioning platform 7 away from the positioning cylinder 3 is vertically connected to the movable baffle 8. Connecting bolts 12 are connected to both the end of the top surface of the positioning push plate 6 away from the positioning cylinder 3 and the end of the bottom surface of the positioning platform 7 near the positioning cylinder 3. A spring 13 is also installed between the two connecting bolts 12. The movable claws 9 include a sliding plate 14, a support plate 15, a roller 16, a gripper 17, and a spring 13. A groove 18 perpendicular to the slide rail 11 is provided in the middle of the plate 5. The slide plate 14 is slidably connected to the groove 18. The support plate 15 is vertically installed on the outer end face of the slide plate 14. The top surface of the support plate 15 is horizontally installed with a gripper 17. The support plate 15 and the base plate 5 are connected with connecting bolts 12. The two ends of the spring 13 are fixedly connected to the support plate 15 and the floor respectively. The top surface of the support plate 15 is rotatably connected to the roller 16 near the slide rail 11. The positioning push plate 6 at the corresponding position is also provided with inclined blocking frames 19 on both sides. When the blocking frame 19 moves, it will drive the rolling to rotate. At the same time, the squeezing roller 16 moves to both sides. When the positioning cylinder 3 extends, it will drive the positioning push plate 6 to move. The positioning platform 7 is also connected to the side near the positioning cylinder 3 with a limit plate 28. A limiting plate 28 is fixedly connected to the front end of the positioning platform 7 as the position reference of the positioning carrier 4. The distance sensor 30 of the former detects the initial positioning of the positioning carrier 4, and the limiting plate 28 can further make the position of the positioning carrier 4 more precise. The distance sensor 30 needs to detect the limiting plate 28 before stopping the rotating disk 2, so that the push block 22 in the positioning cylinder 3 can pass through the gap of the limiting plate 28, and then push the positioning push plate 6 to make the positioning carrier 4 move to clamp the material.

[0027] A longitudinal slide rail 11 is installed in the middle of the base plate 5, and a transverse slide groove 18 is opened. A positioning push plate 6 is connected to the slide rail 11, and a sliding plate 14 is connected inside the slide groove 18. A roller 16 is rotatably connected to the end of the sliding plate 14 near the positioning push plate 6. A blocking frame 19 is connected to the side of the corresponding positioning push plate 6, so that the blocking frame 19 contacts and rolls with the roller 16. That is, when the positioning push plate 6 moves back and forth along the slide rail 11, the blocking frame 19 drives the roller 16 to move left and right along the slide groove 18. A positioning platform 7 is installed at the four corners of the base plate 5 through connecting columns 10. The positioning platform 7 is located above the positioning push plate 6. The front bottom surface of the positioning platform 7 and the rear top surface of the positioning push plate 6 are fixed to the spring 13 by connecting bolts 12. The rear end of the positioning push plate 6 is vertically connected to a movable baffle 8. When the positioning push plate 6 is subjected to force and moves backward, it will... The movable baffle 8 moves backward, while the spring 13 is stretched to store force. After the force is released, the spring 13 resets, which drives the positioning push plate 6 to reset, causing the movable baffle 8 to move forward and reset. The outer end face of the slide plate 14 is vertically connected to the support plate 15, and the support plate 15 is horizontally connected to the gripper 17. The support plate 15 and the base plate 5 are also connected by a spring 13. When the positioning push plate 6 moves, it will squeeze the movable gripper 9 to separate to both sides, causing the gripper 17 to unfold. The spring 13 stretches to store force. After the force is released, the spring 13 resets, causing the movable gripper 9 to move towards the center and reset. This process can unfold the space above the positioning platform 7 and shrink it after reset. It can place materials when unfolded, improving the efficiency of feeding or picking up materials. After reset, it automatically positions and clamps the materials in the front, back, left, and right, which is convenient for processing and has a simple structure that is easy to operate.

[0028] The positioning platform 7 consists of two load plates 23. The positioning platform 7 is also equipped with a first fixed baffle 24 and a second fixed baffle 25. The first fixed baffle is installed on the load plate 23 near the end of the positioning cylinder 3, and the second fixed baffle 25 is installed on the adjacent side of the load plate 23, connecting the two load plates 23 into a whole.

[0029] The first fixed stop 24 is located at the front end of the positioning platform 7 and is fixed in place to form a front and rear positioning clamp with the movable baffle 8 at the rear end. When the movable baffle 8 moves, the front and rear distance increases to facilitate the picking and placing of the workpiece. When the movable baffle 8 resets, the front and rear distance decreases to position and clamp the workpiece. The first fixed stop 24 is always fixed as the front and rear reference plane. Similarly, the second fixed stop 25 is fixed as the left and right reference plane. When it is unfolded in cooperation with the movable claw 9, the workpiece can be picked up and placed quickly. When it is reset, the workpiece can be positioned and clamped, thus improving the positioning and processing efficiency.

[0030] The blocking frame 19 consists of a horizontal rod 26 and a diagonal rod 27. The horizontal rod 26 is installed on the end face of the positioning push plate 6 near the positioning cylinder 3. One end of the diagonal rod 27 is connected to the end face of the horizontal rod 26, and the other end is fixed in the middle of the positioning push plate 6, forming a triangular structure that is wide at the front and narrow at the back and symmetrical from left to right.

[0031] The length range of the horizontal bar 26 determines the movement limit of the roller 16. Under the action of the spring 13, the roller 16 always rolls in contact with the blocking frame 19. The connection point between the horizontal bar 26 and the inclined bar 27 is the maximum rolling point of the roller 16, and the return point of the roller 16 is the rolling origin. The inclined bar 27 acts as a rolling support, allowing the roller 16 to move between the rolling origin and the maximum rolling point. At the same time, the sliding plate 14 moves a distance less than the length of the horizontal bar 26 on the base plate 5, so that the maximum rolling point of the roller 16 is located on the inclined bar 27 and will not reach the connection point between the inclined bar 27 and the horizontal bar 26. This can prevent the roller 16 from detaching from the inclined bar 27. The slope of the inclined bar 27 determines the separation speed of the roller 16. The larger the slope, the steeper the inclined bar 27 and the horizontal bar 26, and the greater the rolling distance of the roller 16, i.e., the greater the separation speed and the greater the return speed. Therefore, adjusting the tilt angle of the inclined bar 27 can control the opening or closing speed of the movable claw 9, which facilitates quick clamping or opening to pick up and put away materials.

[0032] This invention links the movable baffle and the movable claw through a positioning push plate. When the positioning cylinder extends, the push block will squeeze the positioning push plate, and the movable baffle will move backward accordingly. The movable claw will be squeezed by the blocking frame and will separate and open to both sides. The rear end and the left and right ends can be opened simultaneously by the ejection of the linear cylinder, which facilitates the insertion or removal of the workpiece. After the linear cylinder is reset, the movable baffle and the movable claw will be reset by two springs, which tightens the space on the positioning platform and clamps and positions the workpiece. One drive can control the opening or closing in two directions, which simplifies the clamping structure and improves processing efficiency.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
