Description

Technical Field

[0001] This invention relates to a clamping device for cylindrical workpieces, and specifically discloses a multi-station self-centering linkage material stage. Background Technology

[0002] The use of round workpieces is widespread in modern industries, including the valve industry where crucial internal components such as valve cores, seats, and sleeves provide heavy sealing. These parts require high precision and are produced in considerable quantities. With technological advancements, automated processing of these workpieces is becoming increasingly common. This method offers advantages such as low processing costs, stable quality, high efficiency, and production line safety. Automated processing typically consists of processing equipment, robotic arms, control systems, and loading / unloading platforms. The loading / unloading platforms primarily serve as temporary storage for workpieces, and the storage of these workpieces during production requires relatively high precision. Currently, the workpiece positioning on these platforms generally employs the following structure:

[0003] One-to-one tray structure: This structure is mainly designed with special tray tooling based on the external dimensions of the workpiece. Although this method ensures reliable processing and stable quality, it requires frequent tray switching when there are many types of workpieces and processing changes. This results in high tooling investment costs for enterprises and difficulties in on-site storage and management.

[0004] Typical V-shaped positioning structure: This structure is mainly designed based on the outer circle characteristics of the workpiece. Two equal panels with rhomboid cavities are stacked on top of each other. One panel is fixed and the other is a movable panel. The upper and lower rhomboids form a V-shaped positioning. The workpiece is positioned by moving the movable panel to make the V-shape enlarge and shrink. Although this method is simple in structure, it faces the problem that the position of the robot arm is always inconsistent after the workpiece is changed, resulting in long debugging time and low efficiency for workers.

[0005] The above positioning structure seriously affects the company's production efficiency, quality and manufacturing costs. Summary of the Invention

[0079] The working principle of this invention is as follows:

[0080] According to the outer diameter of the workpiece 19, rotate the handwheel 17 clockwise or counterclockwise to adjust the distance between the first V-block 13.1 and the second V-block 14.1 until the workpiece 19 is placed in it and the bottom surface of the workpiece 19 is in contact with the panel 12. Rotate the handwheel 17 clockwise until the first V-shaped opening on the first V-block 13.1 and the second V-shaped opening on the second V-block 14.1 are in contact with the outer circle of the workpiece 29.

[0081] The drive shaft 5 rotates around its axis. The left nut 3 on the drive shaft 5 is fixed to the corresponding slider 2.2 via the first slider connecting plate 6, and the right nut 4 on the drive shaft 5 is fixed to the corresponding slider 2.2 via the second slider connecting plate 7. Therefore, the left nut 3 and the right nut 4 move in opposite directions, causing the first slider connecting plate 6 and the first V-block 13.1 fixed on the first slider connecting plate 6, and the second slider connecting plate 7 and the second V-block 14.1 fixed on the second slider connecting plate 7, to move in opposite directions. The first V-block 13.1 and the second V-block 14.1, moving in opposite directions, combine to form a pair of V-shaped structures. Since adjacent first slider connecting plates 6 are fixed together by first connecting rods 8, and adjacent second slider connecting plates 7 are fixed together by second connecting rods 9, under the drive of the left nut 3, all first slider connecting plates 6 and the first V-blocks 13.1 fixed on the first slider connecting plates 6 move in the same direction. Under the drive of the right nut 4, all second slider connecting plates 7 and the second V-blocks 14.1 fixed on the second slider connecting plates 7 move in the same direction, indirectly forming two first V-blocks 13.1 and two second V-blocks 14.1 translating simultaneously. The synchronous pulley 15 and the synchronous belt 16 rotate to drive the transmission shaft 5 without the handwheel 17, forming four first V-blocks 13.1 and four second V-blocks 14.1 translating simultaneously. The first V-shaped opening on the first V-block 13.1 and the second V-shaped opening on the second V-block 14.1 are used to position and clamp the outer circle of the workpiece 29. The panel 12 supports the bottom surface of the workpiece 19. Rotating the handwheel 17 clockwise finally positions and clamps the workpiece 19 on the device.

[0082] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
