Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a transfer clamp for small inserts of an electric meter box. Background Art

[0002] The meter box consists of a box body, a cover, and inserts embedded in the box body for connection. There are two ways to assemble the inserts: one is to press-fit the inserts into the box body through pre-reserved holes, and the other is to pre-embed the inserts during the box extrusion process. During the pre-embedding process, the inserts need to be arranged and then transferred to the extruder.

[0003] Patent application number CN215066884U discloses an arrangement device for copper inserts in the plug-in housing of an electric meter box. The device comprises a base plate, a vibrating loading tray, a conveying mechanism, a pushing mechanism, and an arrangement mechanism. The base plate is provided with a vibrating loading tray, a conveying mechanism is provided on the base plate behind the vibrating loading tray, the vibrating loading tray is connected to the conveying mechanism, an arrangement mechanism is provided on the base plate in front of the vibrating loading tray, a pushing mechanism is provided on the base plate behind the arrangement mechanism, the conveying mechanism is connected to the pushing mechanism, and the pushing mechanism is connected to the arrangement mechanism. The arrangement device uses the vibrating loading tray, the conveying mechanism, and the pushing mechanism to cooperate with each other to transport the copper inserts one by one in an orderly manner, facilitating the orderly arrangement of subsequent copper inserts and facilitating the clamping and loading operations of subsequent clamping tools.

[0004] After the arrangement device completes the arrangement of the inserts, the inserts are transferred and loaded by clamping. This is typically done using jaws, which undergo a multi-step process of opening, lowering, and closing. This process can lead to low transfer efficiency. Therefore, it is necessary to design a transfer fixture for small inserts in meter boxes to address this issue. Summary of the Invention

[0005] The purpose of the utility model is to provide a transfer fixture for small inserts of an electric meter box which has a simple structure, can be quickly transferred, and effectively improves the transfer efficiency.

[0006] The technical solution of the utility model is:

[0007] A transfer fixture for small inserts in an electric meter box consists of an upper support plate, a lower support plate, an adsorption sleeve and a push rod. The characteristics are: a lower support plate is arranged below the upper support plate, a plurality of adsorption sleeves are arranged at the bottom of the lower support plate, and a vacuum interface is arranged on the circumference of the adsorption sleeve; a push rod is fixed on the upper support plate, and the push rod is movably plug-in connected to the adsorption sleeve.

[0008] The upper support plate is provided with a driving cylinder, and the piston rod end of the driving cylinder is fixedly connected to the lower support plate.

[0009] The driving cylinder is provided with a connecting seat, the connecting seat is provided with a vacuum chamber, and the vacuum chamber is communicated with the vacuum interface through a steel wire hose.

[0012] This transfer fixture for small inserts in meter boxes has a simple structure and is easy to use. It secures the insert within the suction sleeve through vacuum suction, enabling rapid clamping and transfer of the insert, effectively improving transfer efficiency. A push rod ejects the insert, sealing the vacuum port during ejection, removing suction on the insert. This ensures easy and convenient unloading and completes transfer.

[0018] This transfer fixture for small inserts in an electric meter box consists of an upper support plate 1, a lower support plate 2, an adsorption sleeve 3, and a push rod 4. The lower support plate 2 is disposed below the upper support plate 1, and multiple adsorption sleeves 3 are disposed at the bottom of the lower support plate 2. A vacuum interface 5 is provided on the circumference of the adsorption sleeve 3. The push rod 4 is fixed to the upper support plate 1 and movably connected to the adsorption sleeve 3. The adsorption sleeve 3 is used to secure the insert in the adsorption sleeve 3 through the suction force generated by the vacuum interface 5, thereby transferring the insert through the adsorption sleeve 3. The lower support plate 2 can move relative to the upper support plate 1, thereby driving the adsorption sleeve 3 to move during the movement of the lower support plate 2. The function of the push rod 4 is, on the one hand, to guide the movement of the lower support plate 2 through the interaction between the push rod 4 and the adsorption sleeve 3, to prevent the lower support plate 2 from shifting during the movement, and thus to prevent the lower support plate 2 from shifting when driving the adsorption sleeve 3 to move; on the other hand, through the relative movement of the push rod 4 and the adsorption sleeve 3, the push rod 4 is inserted inward into the adsorption sleeve 3, and the transfer of the insert is completed by ejecting the insert in the adsorption sleeve 3.

[0019] A driving cylinder 6 is provided on the upper support plate 1, and the piston rod end of the driving cylinder 6 is fixedly connected to the lower support plate 2, so that the driving cylinder 6 drives the lower support plate 2 to move relative to the upper support plate 1, and then drives the adsorption sleeve 3 to move relative to the push rod 4.

[0020] The drive cylinder 6 is provided with a connection base 7, on which a vacuum chamber 8 is mounted. The vacuum chamber 8 is connected to the vacuum interface 5 via a steel hose. The vacuum chamber 8 is also connected to a vacuum pump, which sequentially creates negative pressure in each adsorption sleeve 3 through the vacuum chamber 8, the steel hose, and the vacuum interface 5. This negative pressure then draws the insert into the adsorption sleeve 3 and simultaneously keeps the insert fixed in the adsorption sleeve 3, allowing the insert to be transferred as the adsorption sleeve 3 moves.

[0021] The top end of the adsorption sleeve 3 is conical in shape and extends above the upper support plate 1. A locking nut 9 is threadedly mounted on the end of the adsorption sleeve 3 extending above the upper support plate 1. Since the top end of the adsorption sleeve 3 is conical in shape, when the locking nut 9 locks the adsorption sleeve 3 to the lower support plate 2, the locking nut 9 can press the end of the adsorption sleeve 3 inward, thereby sealing between the ejector pin 4 and the adsorption sleeve 3, ensuring that the negative pressure in the adsorption sleeve 3 is directed downward, thereby ensuring that the insert can be adsorbed and fixed in the adsorption sleeve 3.

[0022] When the transfer fixture for the small inserts of the meter box is working, after the inserts are arranged, the transfer fixture moves downward (driven by a robotic arm or a cylinder), and the adsorption sleeve 3 is put on the end of the insert. During the downward movement of the adsorption sleeve 3, the vacuum pump is started, and the vacuum pump forms negative pressure in the adsorption sleeve 3 through the vacuum chamber 8, the steel wire hose, and the vacuum interface 5 in sequence, and the insert is adsorbed into the adsorption sleeve 3. After the insert is adsorbed into place, the transfer fixture carrying the insert is transferred to the extruder. After the transfer is in place, the driving cylinder 6 is started, and the driving cylinder 6 drives the lower support plate 2 to move backward, and the push rod 4 pushes the insert out of the adsorption sleeve 3 and fixes it on the extruder. In the process of ejecting the insert, the push rod 4 gradually closes the vacuum interface 6, reducing the suction force on the insert, making it easier to eject the insert.

[0023] This transfer fixture for small inserts in electric meter boxes has a simple structure and is easy to use. It secures the insert within the suction sleeve through vacuum adsorption, enabling rapid clamping and transfer of the insert, effectively improving transfer efficiency. The insert can be ejected by a push rod 4, which seals the vacuum port 6 during ejection, removing suction on the insert, ensuring easy and convenient unloading and completing transfer. This solves the problem of low transfer efficiency caused by the multiple steps involved in existing clamp transfers.
