Description

Technical Field

[0001] This utility model relates to the field of CNC lathe hoisting technology, specifically a device for hoisting internal holes. Background Technology

[0002] A vertical CNC lathe is a CNC machining equipment with a vertically arranged spindle and a horizontally rotating worktable. During the installation of this vertical CNC lathe, it is necessary to vertically clamp the inner roller sleeve for machining. Usually, a hoisting device is used to lift the inner roller sleeve for installation.

[0003] Existing hoisting devices primarily consist of a support frame with a hoisting arm rotatably mounted on it. A lifting device is attached to one end of the hoisting arm, and a chuck is located on the underside of the lifting device. A hydraulic cylinder is rotatably connected to the support frame via a pin. The workpiece is placed on the chuck and secured by binding. The hydraulic cylinder then rotates the hoisting arm to lift the workpiece for installation. However, in practice, after the workpiece is placed on the chuck, it still requires manual pushing to vertically clamp it into the chuck. This pushing poses a safety hazard, as the workpiece may shift and hit one's legs. Furthermore, after hoisting, the workpiece tends to tilt to one side, making it impossible to vertically clamp it into the chuck, thus reducing the installation efficiency of the CNC lathe. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the workpiece tends to tilt to one side after being lifted, and after being placed on the chuck, it still needs to be pushed manually. This not only poses a safety hazard of the workpiece shifting and hitting the legs, but also leads to low installation efficiency. Therefore, this utility model provides a device for lifting internal holes.

Connecting rods are symmetrically mounted on both sides of the connecting seats. Rotating seats are symmetrically fixed on both sides of the horizontal plate.

[0007] As a further embodiment of this utility model: a second pin is rotatably inserted into the inner side of the connecting seat, and the two ends of the second pin are located on the outer side of the connecting seat, and the connecting rod is rotatably installed at both ends of the second pin.

[0008] As a further embodiment of this utility model: the bottom end of the connecting rod is rotatably mounted on the rotating seat, and the horizontal plate is connected to the connecting seat through the connecting rod, and the horizontal plate is perpendicular to the round rod.

[0009] As a further embodiment of this utility model: the control component includes a limiting ring, the limiting ring is fixed to the bottom end of the circular ring, and the limiting ring is slidably fitted onto the bottom end of the circular rod.

[0010] As a further embodiment of this utility model: a spring is connected to the bottom end of the ring, the bottom end of the spring is fixedly connected to the chassis, and the spring is fitted onto the limiting ring.

[0011] As a further embodiment of this utility model: a metal rod is symmetrically fixed to the top side of the ring, and the metal rod is symmetrically arranged at both ends of the ring, with a pull ring fixed to the top of the metal rod.

[0025] Furthermore, a second pin 28 is rotatably inserted inside the connecting seat 27, and both ends of the second pin 28 are located outside the connecting seat 27. The connecting rod 29 is rotatably installed at both ends of the second pin 28.

Moreover, the pin-type connection structure is simple and reliable, and is easy to replace after wear.

[0026] Furthermore, the bottom end of the connecting rod 29 is rotatably mounted on the rotating seat 25, and the horizontal plate 24 is connected to the connecting seat 27 through the connecting rod 29. The horizontal plate 24 is perpendicular to the round rod 1, and the bottom end of the connecting rod 29 is rotatably connected to the rotating seat 25 to form a complete linkage link, realizing the precise conversion between the up-and-down movement of the ring 26 and the opening and closing action of the horizontal plate 24.

[0027] Example 2

[0028] Improvements based on Example 1:

[0029] Furthermore, the control component 3 includes a limiting ring 31, which is fixed to the bottom end of the ring 26 and slidably fitted onto the bottom end of the rod 1. The limiting ring 31 can limit the minimum displacement of the ring 26, prevent excessive sliding, and avoid the inability to lift the workpiece into the inner hole.

[0030] Furthermore, a spring 32 is connected to the bottom end of the ring 26. The bottom end of the spring 32 is fixedly connected to the chassis 21. The spring 32 is fitted onto the limiting ring 31. The spring force of the spring 32 can realize the automatic reset of the ring 26 without manual assistance, thus improving the ease of operation.

[0031] Furthermore, metal rods 33 are symmetrically fixed to the top side of the ring 26, and the metal rods 33 are symmetrically arranged at both ends of the round rod 1. Pull rings 34 are fixed to the top of the metal rods 33. The metal rods 33 are symmetrically arranged at both ends of the round rod 1, and the force is balanced, which makes it convenient for the operator to release the fixation of the workpiece and remove the device for the next hoisting use.

[0032] Furthermore, the fixing mechanism 4 includes a fixing platform 41, which is fixed to the top of the round rod 1. A rectangular groove 42 is provided on the inner side of the fixing platform 41, and fixing rods 43 are symmetrically fixed on the inner side of the rectangular groove 42. The fixing platform 41 is fixed to the top of the round rod 1, and the structure is stable, providing reliable support for the transmission of hoisting tension.

[0033] Furthermore, a connecting platform 44 is fastened to the inner side of the rectangular groove 42, and a fixing rod 43 is inserted and installed inside the connecting platform 44. A pull rod 45 is fixed to the top of the connecting platform 44. The pull rod 45 is fixed to the top of the connecting platform 44, which facilitates connection with the hoisting equipment. At the same time, the pull rod 45 can transmit the pulling force to drive the entire device and the workpiece to be hoisted smoothly.

[0034] Working principle: Connect the tie rod 45 to the hoisting equipment, lift the device and insert it into the inner hole of the furnace inner roller sleeve. At this time, the inner roller sleeve pushes the horizontal plate 24 to retract it. When the horizontal plate 24 is located inside the inner side of the furnace inner roller sleeve, the spring 32 pulls the ring 26 to reset. With the cooperation of the connecting rod 29, the horizontal plate 24 is pushed to reset and become perpendicular to the round rod 1, so that it can be supported inside the inner hole of the furnace inner roller sleeve. At this time, the hoisting force is transmitted to the round rod 1 through the connecting platform 44 and the fixed platform 41, so that with the cooperation of the horizontal plate 24, The workpiece is lifted so that it can be installed inside the CNC lathe. After installation, the pull ring 34 can be pulled to pass through the metal rod 33, causing the ring 26 to slide upward on the rod 1, which in turn moves the connecting rod 29 to pull the horizontal plate 24 to retract it, thereby removing the device from the inside of the furnace roller sleeve. Then, the pull ring 34 is released, and with the cooperation of the spring 32, the horizontal plate 24 is reset for the next lifting use. This device does not require manual pushing or adjustment and can complete the clamping safely and efficiently.
