Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inner hole surfacing, in particular to a vertical rotating device for inner hole surfacing of a workpiece. Background Art
[0002] The inner hole is also called the internal hole. The internal hole surfacing is mainly used to repair the damage, defects, and awkwardness of various molds, hot forging molds, valve rollers, valve sleeves, and internal holes; it is used to enhance the wear resistance and wear-resistant hot corrosion performance of precision molds and inner wall surfaces; it can achieve metallurgical bonding, no breakage, no cracks and faults at room temperature; there is no thermal deformation, annealing and softening phenomenon under production stress. When surfacing the circular inner hole, a vertical rotating device is usually used to rotate the workpiece, so as to facilitate the welding gun to perform surfacing operations on the annular surface.
[0003] The existing workpiece inner hole surfacing vertical rotating device needs to limit the workpiece by a clamp when in use. The clamps are mainly divided into manual clamps, pneumatic clamps, hydraulic clamps and electric clamps. The operation of manual clamps is relatively cumbersome, and usually several clamps are operated separately. Each time the disassembly and assembly is performed, the staff is required to manually end the limiting of several clamps, or install several clamps in place, which is time-consuming and labor-intensive. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a vertical rotating device for surfacing welding of inner holes of workpieces to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical rotating device for surfacing welding of inner holes in a workpiece, comprising a frame and a device body, a first spring is connected to the lower part of the inside of the device body, and a support frame is connected to the top of the first spring, a control ring is connected to the outer surface of the device body, a slide groove is opened on the top of the device body, and a clamping block passes through the top of the slide groove, a pull rope is connected between the clamping block and the control ring, a bracket is connected to one side of the top of the device body, and a second spring is connected inside the bracket.
[0006] By adopting the above technical solution, the workpiece is placed on the top of the support frame, and then the workpiece is pressed down to move the support frame downward and compress the first spring. After the support frame moves downward, the limiting of the clamping block is ended. At this time, the second spring pushes the clamping block to move toward the workpiece to clamp the workpiece; after the surfacing is completed, the control ring is rotated counterclockwise to pull the pull rope. At this time, the pull rope pulls the clamping block, so that the clamping block moves away from the workpiece and compresses the second spring to end the limiting of the workpiece. After the clamping block moves away, the limiting of the support frame is ended, and then the support frame is driven upward by the first spring to push the workpiece out. After the support frame moves upward, the clamping block is supported to prevent the clamping block from moving toward the workpiece.
[0007] Furthermore, the abutment frame is slidably connected to the device body, and the clamping block and the abutment frame abut against each other.
[0008] By adopting the above technical solution, the staff places the workpiece on the top of the support frame, and then presses the workpiece downward to move the support frame downward, thereby completing the limiting of the clamping block.
[0009] Furthermore, the clamping block is slidably connected to the device body via a sliding groove, and one end of the second spring is connected to the clamping block.
[0010] By adopting the above technical solution, the clamping block can be displaced toward the workpiece to clamp the workpiece, and conversely, the clamping block moves away from the workpiece to stop limiting the workpiece.
[0011] Furthermore, the control ring is rotatably connected to the device body, and handles are fixed on both sides of the control ring.
[0012] By adopting the above technical solution, the staff rotates the control ring counterclockwise to pull the pull rope, and the pull rope pulls the clamping block, thereby moving the clamping block away from the workpiece and compressing the second spring to end the limitation of the workpiece.
[0013] Furthermore, the pull rope is a steel wire rope.
[0014] By adopting the above technical solution, the clamp block and the control ring are linked by transmitting the pulling force through the pull rope, and the steel wire rope used as the pull rope has the advantages of high structural strength and long service life.
[0015] Furthermore, a "V"-shaped groove is provided on one side of the clamping block.
[0016] By adopting the above technical solution, the V-shaped groove on the side of the clamp block can increase the contact surface between the clamp block and the workpiece, thereby increasing the friction force to prevent the workpiece from being displaced and falling off.
[0017] Furthermore, there are four of each of the bracket, clamp block, slide groove, first spring and pull rope, and four groups of second springs. The four groups of second springs and the four brackets, clamp blocks, slide grooves, first springs and pull ropes are distributed in a circular array.
[0018] By adopting the above technical solution, the staff presses the workpiece downward to move the support frame downward. After the support frame moves downward, the four first springs are compressed and the limiting of the four clamping blocks is ended. At this time, the four groups of second springs push the four clamping blocks to move toward the workpiece to clamp the workpiece. At the same time, the four clamping blocks pull the four pull ropes, so that the four pull ropes pull the control ring to rotate clockwise.
[0019] Furthermore, a hydraulic cylinder is installed on the top of the frame, and a welding gun is connected to the output end of the hydraulic cylinder. A motor is installed inside the frame, and the device body is connected to the output end of the motor.
[0020] By adopting the above technical solution, after clamping the workpiece, the staff turns on the hydraulic cylinder, welding gun and motor. After the motor is started, the output end drives the main body of the device to rotate slowly, thereby driving the workpiece to rotate slowly. The slow rotation can avoid the welding being too fast resulting in loose welding, and the clamping block being away from the workpiece due to large centrifugal force. After the hydraulic cylinder is started, the output end drives the welding gun to move downward, so that the head of the welding gun enters the inner hole of the workpiece. After the welding gun is started, the surfacing work begins. After the surfacing is completed, the staff turns off the hydraulic cylinder, welding gun and motor, moves the welding gun upward and stops the main body of the device.
[0021] Furthermore, slide plates are fixed on both sides, the outer surface and the back of the support frame, and the slide plates are made of Teflon material.
[0022] By adopting the above technical solution, Teflon has a self-lubricating effect and a low friction coefficient, which can effectively reduce the friction between the clamping block, thereby extending the service life of the structure.
[0023] Furthermore, a plurality of the slide plates are provided, and the plurality of slide plates are distributed in a ring array.
[0024] By adopting the above technical solution, the staff presses the workpiece downward to move the support frame downward, and the support frame reduces the friction between the clamping block through the slide plate while moving.
[0025] In summary, the utility model mainly has the following beneficial effects:
[0026] The utility model places the workpiece on the top of the support frame through the arrangement of a control ring, a clamping block, a sliding groove, a support frame, a first spring, a second spring, a pulling rope and a sliding plate, and then presses the workpiece downward to make the support frame move downward and compress the first spring. After the support frame moves downward, the limiting of the clamping block is ended, and at this time, the second spring pushes the clamping block to move toward the workpiece to clamp the workpiece; after the surfacing welding is completed, the control ring is rotated counterclockwise to pull the pulling rope, and at this time, the pulling rope pulls the clamping block, thereby making the clamping block move away from the workpiece and compressing the second spring to end the limiting of the workpiece, and the limiting of the support frame is ended after the clamping block moves away, and then the support frame is driven by the first spring to move upward to push out the workpiece, and after the support frame moves upward, the clamping block is supported to prevent the clamping block from moving toward the workpiece; the operation is simple and convenient, and it is convenient for quick clamping and ending the limiting.

[0034] The following describes an embodiment of the utility model based on its overall structure.

The inside of the bracket 7 is connected with the second spring 12, one end of the second spring 12 is connected to the clamp block 8, and the second spring 12 is provided with four groups. The four groups of second springs 12 and the four brackets 7, clamp block 8, slide groove 9, first spring 11 and pull rope 13 are distributed in a circular array. The second spring 12 pushes the clamp block 8 to move toward the workpiece to clamp the workpiece. At the same time, the clamp block 8 pulls the pull rope 13, so that the pull rope 13 pulls the control ring 6 to rotate clockwise.
[0037] See also Figure 1 and Figure 2In the above embodiment, a hydraulic cylinder 2 is installed on the top of the frame 1, and a welding gun 3 is connected to the output end of the hydraulic cylinder 2. A motor 4 is installed inside the frame 1, and a device body 5 is connected to the output end of the motor 4. After the motor 4 is started, the output end drives the device body 5 to rotate slowly, thereby driving the workpiece to rotate slowly. After the hydraulic cylinder 2 is started, the output end drives the welding gun 3 to move downward, so that the head of the welding gun 3 enters the inner hole of the workpiece, and the surfacing work starts after the welding gun 3 is started.
[0038] Embodiment 2:
[0039] On the basis of the above-mentioned embodiment 1, although the control ring 6, the clamping block 8, the slide groove 9, the support frame 10, the first spring 11, the second spring 12, the pull rope 13 and the slide plate 14 are provided, the operation can be simple and convenient, and the effect of quick clamping and ending the limit can be achieved; but the friction between the clamping block 8 and the support frame 10 is relatively large; now by providing the slide plate 14, the friction can be reduced and thus the wear can be reduced.
[0040] See also Figure 3-Figure 5 In the above embodiment, slide plates 14 are fixed on both sides, the outer surface and the back of the support frame 10. The slide plates 14 are made of Teflon material. There are multiple slide plates 14, which are distributed in a circular array. When the support frame 10 is displaced, the slide plates 14 can reduce the friction between it and the clamping block 8.
[0041] The implementation principle of the utility model is as follows: first, the staff places the workpiece on the top of the support frame 10, and then the staff presses the workpiece downward to move the support frame 10 downward. While the support frame 10 is moving, the friction between the support frame 10 and the clamping block 8 is reduced by the slide plate 14. After the support frame 10 moves downward, the first spring 11 is compressed and the limit of the clamping block 8 is ended. At this time, the second spring 12 pushes the clamping block 8 to move toward the workpiece to clamp the workpiece. At the same time, the clamping block 8 pulls the pull rope 13, so that the pull rope 13 pulls the control ring 6 to rotate clockwise;
[0042] After clamping the workpiece, the staff turns on the hydraulic cylinder 2, the welding gun 3 and the motor 4. After the motor 4 is started, the output end drives the device body 5 to rotate slowly, thereby driving the workpiece to rotate slowly. The slow rotation is to avoid the welding being not firm due to too fast rotation speed, and to avoid the clamping block 8 being away from the workpiece due to large centrifugal force. After the hydraulic cylinder 2 is started, the output end drives the welding gun 3 to move downward, so that the head of the welding gun 3 enters the inner hole of the workpiece. After the welding gun 3 is started, the surfacing work begins. After the surfacing is completed, the staff turns off the hydraulic cylinder 2, the welding gun 3 and the motor 4, so that the welding gun 3 moves upward and the device body 5 stops rotating.
[0043] After the surfacing work is completed, the staff rotates the control ring 6 counterclockwise to pull the pull rope 13. At this time, the pull rope 13 pulls the clamp block 8, so that the clamp block 8 moves away from the workpiece and compresses the second spring 12 to end the limitation of the workpiece. After the clamp block 8 moves away, the limitation of the support frame 10 is ended. Then, the support frame 10 is driven upward by the first spring 11 to push the workpiece out. At this time, the staff can take out the workpiece and start unloading, and the support frame 10 moves up to hold the clamp block 8 to prevent the clamp block 8 from moving toward the center of the device body 5, so that the staff only needs to place the workpiece on the top of the support frame 10 and press it down when working next time.
[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
