Description

Technical Field

[0001] The present application relates to the technical field of hoisting and clamping during ingot machining, and in particular to a hoisting and leveling support device before ingot clamping processing. Background Art

[0002] After the ingot is smelted and formed, its surface is relatively rough due to the influence of voltage, current and temperature drop in the late stage of smelting. Therefore, after the smelting is completed, the surface of the ingot needs to be processed, such as turning the surface and end face to improve its surface flatness. In order to reduce the smelting energy consumption, the size of the ingot for a single smelting is usually large, so it is usually necessary to hoist the ingot to the machine tool for processing, as shown in the attached manual. Figure 1-2 Status shown.

[0003] Currently, before hoisting the ingot, it is necessary to insert hoisting wire ropes or slings on the left and right sides of its bottom, and then hoist it between the left top column in the machine tool clamping claw and the right top column of the rear tailstock through the hook, and make the left top column embedded in the center blind hole of the ingot end face opened in advance, and then embed it into the center blind hole on the other side through the right top column of the rear tailstock, and finally clamp and tighten the circumference of one side of the ingot through the clamping claw, remove the wire rope, and then carry out the surface processing operation of the ingot.

[0004] However, when the steel wire ropes are currently passed through the two sides of the bottom of the ingot, the positions of the steel wire ropes on the left and right sides are asymmetrical due to human factors, and the length of the steel wire ropes is inconsistent. As a result, during the lifting process, the ingot cannot be kept in a horizontal state, and there will be axial deviation, such as Figure 3 As shown, when the ingot is lowered into the machine tool in this state, it only corresponds to the left top column or the right top column horizontally, but not to both at the same time, which will cause the top column on one side to be unable to be smoothly embedded in the central blind hole of the ingot end face (as shown in FIG. Figure 4 As shown in the figure, if the holes on the left side are aligned, the left side will be lowered simultaneously when the right side is aligned. After the right side is aligned, the left side will not be aligned. Usually, the ingot needs to be placed on the ground again to adjust the wire rope lifting position. However, the adjustment process usually cannot be achieved in one go and requires multiple adjustments. This results in repeated lifting and lowering adjustments, which makes it difficult to horizontally clamp the ingot. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a hoisting and leveling support device before the ingot clamping process, which can adjust the ingot in the hoisting state to a horizontal state, and solve the difficulty of frequent hoisting and lowering for ground leveling due to the current ingot hoisting deviation and inability to correspond synchronously with the left top column and the right top column, thereby improving the operational efficiency of ingot clamping.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a hoisting and leveling support device for the ingot before clamping processing, one end of the ingot is clamped on the clamping claw of the machine tool and the two end faces of the ingot are supported on the left top column in the clamping claw and the right top column located at the rear tailstock of the machine tool, and is characterized in that: the hoisting and leveling support device supports the ingot in the hoisting state at the bottom of one side of its end face corresponding to the left top column or the right top column.

[0007] Preferably, the hoisting and leveling support device includes a slide seat arranged in the machine tool and parallel to the ingot clamping direction, a telescopic rod is arranged on the slide seat, and an arc-shaped support plate in contact with the bottom surface of the ingot is arranged at the top of the telescopic rod.

[0008] Preferably, the arc-shaped support plate is hinged on the telescopic rod along the length direction of the ingot.

[0009] Preferably, a driving screw rod is provided on each side of the slide seat and is detachably connected to the bottom of the telescopic rod.

[0010] The beneficial effect of the present application is that the lower side of the ingot in the hoisting state is contact-supported by the hoisting and leveling support device, while the higher side of the ingot can be lowered and leveled separately, so that the ingot can be adjusted to a horizontal state in the hoisting state and correspond horizontally with the left top column and the right top column on the machine tool, thereby realizing rapid clamping of the ingot, solving the current operational difficulty of frequent hoisting and lowering for ground leveling due to the ingot hoisting deviation and failure to correspond synchronously with the left top column and the right top column, thereby improving the operational efficiency of ingot clamping.

[0024] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Refer to the attached Figures 1 to 11 The shown device is a lifting and leveling support device for ingot clamping before processing, in which one end of the ingot is clamped on the jaws of the machine tool and the two end faces of the ingot are supported on the left top column 11 in the jaws and the right top column 12 located at the rear tailstock of the machine tool. The specific clamping process is: first, the two end faces of the ingot are supported on the left top column 11 and the right top column 12, so that the ingot and the machine tool spindle are in a coaxial state, and then each clamping jaw is operated separately to make it tightly adhere to the circumference of the ingot for clamping. The purpose of operating the clamping jaws separately is because the surface of the ingot is uneven, and uniformly locking multiple clamping jaws will cause inconsistent contact states with the surface of the ingot, resulting in the axis of the ingot being deviated from the machine tool spindle. Therefore, after the left top column 11 and the right top column 12 horizontally support the ingot, each clamping jaw is locked one by one to the circumference of the ingot.

[0026] In order to solve the problem that the ingot is tilted in the horizontal direction during the current hoisting process and cannot be embedded in the left top column 11 and the right top column 12 in a synchronous manner, the present application is provided with a hoisting leveling support device, which supports the ingot in the hoisting state at the bottom of the side corresponding to the ingot end face and the left top column 11 or the right top column 12. The specific operation is as follows Figure 5As shown, when the ingot is hoisted and lowered into the machine tool for clamping, if the central blind hole on the left end face of the ingot is horizontally aligned with the left top column 11, that is, in this state, the bottom of the ingot on this side is supported by the hoisting and leveling support device, as shown in FIG. Figure 5 As shown, the ingot is then lowered. Since the left side of the ingot has been supported by the hoisting and leveling support device, the (left) side always remains corresponding to the left top column 11 during the process of lowering the ingot. Figure 6 As shown, when the ingot continues to be lowered, the central blind hole on the right end face gradually corresponds to the right top column 12, so that the central blind holes on both end faces of the ingot correspond to the left top column 11 and the right top column 12 respectively and synchronously, and then the left top column 11 and the right top column 12 are embedded in the central blind holes on the end faces of the ingot to achieve horizontal support for the ingot, and finally the claws are locked on the circumference of one side of the ingot and the wire rope is removed, and the surface processing operation of the ingot can be carried out.

[0027] Specifically, such as Figure 5 As shown, the hoisting and leveling support device includes a slide 2 arranged in the machine tool and parallel to the ingot clamping direction, a telescopic rod 3 (preferably a threaded telescopic rod) is arranged on the slide 2, and an arc-shaped support plate 4 is arranged at the top of the telescopic rod 3 to contact the bottom surface of the ingot. The bottom of the arc-shaped support plate 4 is rotatably connected to the top of the telescopic rod 3. When in use, first, according to the tilt state of the ingot after lifting, the telescopic rod 3 is slid on the slide 2 to the bottom of the lower end of the ingot, as shown in FIG. Figure 5 As shown in the left side, the ingot is then lowered. After the central blind hole on the left end face corresponds to the left top column 11, the handle on the telescopic rod 3 is rotated to extend the telescopic rod 3, and the arc-shaped support plate 4 is in contact with the bottom surface of the left side of the ingot to support the left side of the ingot; then the ingot is continued to be lowered, as shown in the right side. Figure 6 As shown, the central blind hole on the right end face of the ingot gradually corresponds to the right top column 12, and then the left top column 11 and the right top column 12 are embedded in the central blind hole on the end face of the ingot, so as to realize the horizontal adjustment support operation of the ingot in a single hoisting state, solve the difficulty of the current frequent lifting and lowering operations, and realize the rapid horizontal clamping of the ingot. When the ingot is processed, Figure 9 As shown, the telescopic rod 3 is rotated in the opposite direction so that the arc-shaped support plate 4 is out of contact with the ingot, thereby avoiding interference during the processing.

[0028] After the left bottom of the ingot is supported by the arc-shaped support plate 4, when the ingot is continued to be lowered so that the right end face corresponds to the right top column 12, the ingot will use the support of the arc-shaped support plate 4 as the deflection base point, so that the right side of the ingot continues to deflect downward, and the ingot as a whole will rotate downward, while the arc-shaped support plate 4 is flat against the left bottom surface of the ingot, so that there is a certain interference in the downward deflection of the ingot. Therefore, in order to solve this problem, as shown in FIG. Figure 6As shown, the arc-shaped support plate 4 is hinged on the telescopic rod 3 along the length direction of the ingot, so that when the ingot is deflected and lowered to the right side, the arc-shaped support plate 4 can deflect along with it, thereby solving the interference effect caused by the deflection of the ingot.

[0029] The left top column 11 usually set in the machine tool chuck is fixed in position. Therefore, after the center blind hole of the ingot end face is aligned, the right top column 12 on the rear tailstock is extended and first embedded in the center blind hole in the right end face of the ingot, and then the ingot is driven toward the chuck so that the left top column 11 can be embedded in the center blind hole of the left end face. When the ingot is in a hoisting state, the axial drive of the ingot by the right top column 12 will cause contact impact on the left top column 11 during the movement of the ingot (the overall weight of the ingot is usually measured in tons), and then frequent processing will cause the stability of the left top column 11 to decrease, affecting the subsequent clamping accuracy. Therefore, in order to further solve this problem, Figure 10 As shown, a drive screw 5 detachably connected to the bottom of the telescopic rod 3 is provided on each side of the slide 2. When the arc-shaped support plate 4 supports one side of the ingot, the bottom side of the telescopic rod 3 is connected to the drive screw 5 on the corresponding side, as shown in FIG. Figure 10 As shown, the left side of the ingot is supported, and then the ingot is lowered and adjusted to a horizontal state, and the telescopic rod 3 can be pulled to Figure 10 The ingot is moved in the direction of the middle arrow, while the arc-shaped support plate 4 still supports the ingot. Therefore, the contact friction between the two simultaneously drives the ingot to move steadily toward the left top column 11 and embed it, and then drives the rear tailstock to embed the right top column 12 into the other end face of the ingot. At the same time, after the screw rod 5 is driven to connect with the telescopic rod 3, the arc-shaped support plate 4 can be limited, and the ingot is also restrained accordingly, preventing the telescopic rod 3 from sliding freely on the slide 2 due to the shaking of the ingot.

[0030] Similarly, when the arc-shaped support plate 4 supports the right bottom of the ingot, as shown in FIG. Figure 11 As shown, after the ingot is lowered and adjusted to a horizontal state, the drive screw 5 on this side is rotated to drive the telescopic rod 3 to move toward the chuck, thereby synchronously driving the left end face of the ingot to steadily nest on the left top column 11, and then driving the rear tailstock to embed the right top column 12 into the other side end face of the ingot, thereby solving the impact of the ingot in the hoisting state on the left top column 11.

[0031] The principle of this application is as follows: when the ingot is clamped on the machine tool, the ingot is lifted by a wire rope or other lifting device and lifted from the bottom of the top side of the machine tool. After the center blind hole on the lower end surface of the ingot is horizontally aligned with the left top column 11 or the right top column 12, the arc support plate 4 is slid on the slide 2 to the bottom of the ingot on this side and connected to the driving screw 5, and the telescopic rod 3 is rotated to make the arc support plate 4 contact and support the bottom surface of the ingot, and then the ingot is continued to be lowered so that the center blind hole on the other end surface of the ingot is horizontally aligned with the left top column 11 or the right top column 12, and then the driving screw 5 is rotated to drive the arc support plate 4 and the ingot to move toward the left top column 11 and nested on the left top column 11, and then the right top column 12 on the rear tailstock is driven to be embedded in the other end surface of the ingot, and finally the clamping claw is locked, the wire rope is removed and the arc support plate 4 is lowered, and the ingot processing operation can be carried out.

[0032] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
