Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, in particular to a hoisting device of the disc sleeve type for a vertical lathe. Background Art

[0002] Vertical CNC lathe processing workpiece has the advantages of good stability, high processing precision, high processing efficiency, strong adaptability, low cost and easy operation. Among them, the disk sleeve type workpiece is one of its processing range. The disk sleeve is made of round steel by vertical CNC lathe.

[0003] At present, the hoisting of round steel is generally completed by clamps. The schematic diagram of the existing clamps is attached to the manual. Figure 3 As shown in , the principle is that the sling descends to release the clamping of the round steel, and the sling moves up to realize the horizontal movement of the clamping plate to complete the clamping of the round steel. This type of clamp has a simple structure and has a self-clamping and locking function, but there are the following disadvantages in the specific use process:

[0004] After the round steel is accurately clamped and placed on the chuck of the vertical CNC lathe, it needs to be transferred immediately so as not to hinder subsequent processing. However, if the fixture is lifted up for transfer, the fixture will clamp the round steel again. This makes it impossible to automatically and quickly achieve contactless separation between the round steel and the fixture, and the lifting effect needs to be further improved. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a plate sleeve type lifting device for a vertical lathe.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A disk sleeve type lifting device for a vertical lathe comprises a clamp, the clamp comprises a mounting seat and a rotating roller, one end of the rotating roller is connected to a locking roller, a first frame body and a counterweight assembly are respectively arranged on both sides of the mounting seat, an automatic locking assembly is arranged on the first frame body, and the automatic locking assembly cooperates with the locking roller to be used for locking the clamp when it rises away from round steel.

[0008] After the round steel is placed on the chuck of the CNC machine tool, the device can automatically lock the clamp and facilitate the subsequent lifting of the clamp away from the round steel. At this time, the clamp's clamping plate will not clamp the round steel for the second time during the lifting process, and the non-contact separation between the clamp and the round steel can be achieved, further improving the lifting effect.

[0009] Furthermore, the counterweight assembly includes a second frame and a counterweight block. The mounting seat is provided with a second frame symmetrically arranged with respect to the first frame, and the counterweight block is symmetrically arranged on the second frame.

[0010] The above solution achieves the balance of the clamp through a counterweight assembly.

[0011] Furthermore, a sensor is provided on the clamping plate of the clamp.

[0012] The above scheme can detect the distance between the clamp and the chuck in real time through the distance sensor. If the distance between the two is within the pre-set height range of the distance sensor, it can be determined that the round steel has been placed on the chuck. Then the distance sensor can feedback the signal to the controller, and then the controller controls the automatic locking component to operate to lock the locking roller. Then the clamp is locked and can be moved away from the round steel in a non-contact manner so as not to hinder the subsequent CNC processing process.

[0013] Furthermore, the automatic locking component includes a telescopic component and an arc plate. The telescopic component is symmetrically arranged on the first frame. The telescopic component is connected to the arc plates that are distributed opposite each other and move toward or away from each other synchronously. The arc plates cooperate with the locking rollers.

[0014] Furthermore, a rubber layer is provided on the inner wall of the arc-shaped plate.

[0015] Furthermore, the automatic locking component includes a telescopic component and an arc plate. A group of telescopic components is arranged on the first frame, the telescopic components are connected to the arc plate, a magnet is arranged on the arc plate, and the locking roller is made of metal.

[0016] Furthermore, the arc plate is a semi-arc plate or a V-shaped plate.

[0017] Furthermore, the first frame and the second frame are both movably mounted on a mounting seat.

[0018] The two frames in the above solution are easy to disassemble for replacement or maintenance of parts.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] Compared with the prior art, the device can automatically lock the clamp after the round steel is placed on the chuck of the CNC machine tool, thereby facilitating the subsequent lifting of the clamp away from the round steel. At this time, the clamp's clamping plate will not clamp the round steel for the second time during the rising process, thereby achieving contactless separation between the clamp and the round steel, and further improving the lifting effect.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0027] like Figure 1 and Figure 2 As shown, a disk sleeve type lifting device for a vertical lathe includes a clamp 11, which includes a mounting seat 11 and a rotating roller 101. One end of the rotating roller 101 is connected to a locking roller 102. A first frame 12 and a counterweight assembly are respectively provided on both sides of the mounting seat 11. An automatic locking assembly is provided on the first frame 12. The automatic locking assembly cooperates with the locking roller 102 to be used for locking the clamp 1 in the process of rising away from the round steel.

[0028] The first embodiment of the automatic locking assembly:

[0029] The specific implementation of the first embodiment of the utility model is as follows Figure 1 As shown, the automatic locking component includes a telescopic component 14 and a curved plate 15. The telescopic component 14 is symmetrically arranged on the first frame 12. The telescopic component 14 is connected to the curved plates 15 that are distributed opposite each other and move toward or away from each other synchronously. The curved plates 15 cooperate with the locking roller 102. In a further optimization of the above embodiment, a rubber layer is arranged on the inner wall of the curved plate 15; the rubber layer can reduce the wear between the curved plate 15 and the locking roller 102.

[0030] Second embodiment of automatic locking assembly:

[0031] In the specific implementation of the second embodiment of the utility model, the automatic locking component includes a telescopic component 14 and an arc plate 15. A group of telescopic components 14 are arranged on the first frame 12, and the telescopic components 14 are connected to the arc plate 15. A magnet is arranged on the arc plate 15 and the locking roller 102 is made of metal. This embodiment is not shown in the figure. The above embodiment is further optimized. The arc plate 15 is one of a semi-arc plate or a V-shaped plate; the movement of a group of telescopic components 14 can drive the magnet to contact the locking roller 102 to achieve adsorption limiting.

[0032] Further refinement of the embodiment of the present utility model is as follows: Figure 2 As shown, the counterweight assembly includes a second frame 21 and a counterweight 22 . The mounting seat 11 is provided with the second frame 21 symmetrically arranged with respect to the first frame 12 , and the counterweight 22 is symmetrically arranged on the second frame 21 .

[0033] It should be noted that the telescopic assembly 14 is electrically connected to the controller, which is not shown in the figure.

[0034] The workflow of this utility model:

[0035] First, the round steel required for preparing the disc sleeve is clamped by the clamp 1 and placed on the chuck of the CNC machine tool, which is not shown in the figure. When the round steel is accurately placed on the chuck, the controller immediately controls the automatic locking component to work and thereby realizes the position limitation of the locking roller 102. At this time, the position of the rotating roller 101 can be limited, and then no matter whether the clamp 1 is rising or falling, the clamp plate of the clamp 1 will not move horizontally. Then the lifting clamp 1 can be hoisted to make the clamp 1 separate from the round steel and move away from it, and then the round steel can be processed to prepare the disc sleeve. When the clamp 1 is away from the round steel, the controller immediately controls the automatic locking component to release the lock on the locking roller 102, and then the clamp 1 can clamp and transport the new round steel again.

[0036] Compared with the prior art, the device can automatically lock the clamp 1 immediately after the round steel is placed on the chuck of the CNC machine tool, thereby facilitating the subsequent ascent of the clamp 1 away from the round steel. At this time, the clamp 1's clamping plate will not perform secondary clamping on the round steel during the ascent process, thereby achieving contactless separation between the clamp 1 and the round steel, and further improving the lifting effect.

[0037] In some embodiments, Figure 1 As shown, a sensor 3 is provided on the clamping plate of the clamp 11, and the sensor 3 is specifically a distance sensor. This embodiment can detect the distance between the clamp 1 and the chuck in real time through the distance sensor. If the distance between the two is within the height range preset in the distance sensor, it can be determined that the round steel has been placed on the chuck. Then the distance sensor can feedback a signal to the controller, and then the controller controls the operation of the automatic locking component to lock the locking roller 102 and thus complete the locking of the clamp 1.

[0038] In other embodiments, the first frame 12 and the second frame 21 are both movably mounted on the mounting base 11 ; the two frames in this embodiment are convenient to be disassembled for replacement or maintenance of parts.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
