Description

Technical Field

[0001] The utility model relates to the technical field of beveling machines, in particular to a large-scale numerical control beveling machine. Background Art

[0002] A beveling machine is a special device for chamfering and beveling the front end face of a pipeline during welding. Generally, when processing a steel cylinder, the steel cylinder is first fixed on the beveling machine, and then a beveling tool rotates around the steel cylinder to cut the end face of the steel cylinder. For example, when a boiler pipeline needs to be ground to form a bevel at the welding position, the diameter of such a boiler pipeline is large and heavy. The traditional cutting method uses a cross-axis and a longitudinal axis to control the tool, which is not convenient enough. In this case, a beveling machine is needed to process the boiler pipeline.

[0003] For example, a beveling machine disclosed in Chinese Patent Document CN211539771U includes a clamping mechanism and a spindle device arranged on a base. The spindle device includes a frame. A cutter head is arranged on one side of the frame close to the clamping mechanism. A spindle is rotatably arranged on the side of the cutter head away from the clamping mechanism. The cutter head is fixed on the end face of the spindle and is provided with a tool for cutting the end face of the steel cylinder. The clamping mechanism includes a first clamping jaw and a second clamping jaw arranged oppositely. The first clamping jaw and the second clamping jaw approach or move away from each other through the transmission of a rack and a gear, so as to clamp the steel cylinder. From the structure of the above beveling machine, it can be seen that the two clamping jaws of such a clamping mechanism are generally suitable for clamping smooth steel pipes. Existing steel pipes, as Figure 5 shown, have a plurality of connecting pipes welded on the side wall at one end. The plurality of connecting pipes are arranged at intervals along the axial direction of the steel pipe and are on the same straight line. This results in a position interference between the connecting pipes and the clamping jaws, so that the clamping mechanism cannot meet the clamping requirements for such steel pipes, has certain limitations, a small applicable range, and affects the use performance of the product. Summary of the Utility Model

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the position interference between the connecting pipes on the steel pipe and the clamping jaws in the prior art, so that the clamping mechanism cannot meet the clamping requirements for such steel pipes, has a small applicable range, and affects the use performance of the product.

[0005] To solve the above technical problem, the utility model provides a large-scale numerical control beveling machine, which includes a cutter head mechanism and a clamping mechanism arranged on a frame.

An installation cavity extending in the same direction as the first slide rail is provided in the first slide rail. The two driving platforms respectively include two first sliding seats slidably connected to the first slide rail. A moving connection is formed between the two driving platforms through a screw rod structure. The screw rod structure includes a screw rod shaft rotatably arranged in the installation cavity, two nut seats respectively arranged at the bottoms of the two first sliding seats and threadedly connected to the screw rod shaft, and a coupling connected to one end of the screw rod shaft.

The two adjusting plates are respectively provided with T-shaped sliding blocks that are slidably connected to the T-shaped sliding grooves in a matching manner.

[0013] In the above-mentioned large CNC beveling machine, the two driving platforms respectively include two installation blocks connected to the two adjusting plates. The two T-shaped sliding grooves are respectively arranged opposite to the two installation blocks. A height adjusting mechanism for driving the installation block to move in the Z-axis direction is arranged on the driving platform.

[0014] In the above-mentioned large CNC beveling machine, the height adjustment structure is an oil cylinder structure arranged on the driving table, which includes an oil cylinder body and a piston rod movably penetrating through the oil cylinder body. A receiving groove suitable for accommodating the oil cylinder body and the piston rod is provided in the driving table. Two limiting plates are arranged up and down opposite to each other in the receiving groove. The mounting block is fixedly connected to the outer wall of the oil cylinder body.

[0016] In the above-mentioned large CNC beveling machine, it further includes a third slide rail extending along the X-axis direction and arranged on one side of the clamping mechanism, and at least one support mechanism slidably arranged on the third slide rail, so that the steel pipe abuts against the support mechanism.

[0017] In the above-mentioned large CNC beveling machine, the support mechanism includes a pulley base slidably connected to the third slide rail, and two support seats relatively movably arranged on the pulley base. Two groups of inclined plate structures are oppositely arranged on the two support seats, and a support opening opposite to the clamping opening is formed between the two groups of inclined plate structures.

[0018] The technical solution of the present utility model has the following advantages compared with the prior art:

[0019] 1. In the large numerical control beveling machine provided by the present utility model, two groups of clamping piece assemblies are respectively inserted on two adjusting plates. Each group of clamping piece assemblies includes a plurality of clamping pieces arranged at intervals on the adjusting plate, and a plurality of partition grooves are formed between the plurality of clamping pieces. The advantage of this design is that during operation, the two driving platforms move towards each other to drive the two groups of clamping piece assemblies to clamp the steel pipe. At the same time, a plurality of connecting pipes arranged at intervals on one side wall of one end of the steel pipe are respectively received in the plurality of partition grooves, and the plurality of partition grooves are exactly adapted to the positions of the plurality of connecting pipes. Even in the case of position interference between the connecting pipe and the clamping piece, the position relationship between the clamping piece and the connecting pipe can be adaptively adjusted by moving the adjusting plate, or a certain clamping piece can be removed to make way for the connecting pipe, so as to ensure that the clamping mechanism clamps the steel pipe while avoiding the situation of position interference between the clamping piece and the connecting pipe. Finally, as long as the steel pipe is processed by the cutter head mechanism for automatic beveling, the performance is stable, and the smoothness and bevel accuracy of the bevel processing surface are ensured. The clamping mechanism adopted by this beveling machine can meet the processing and use requirements of steel pipe products with connecting pipes, has a wide application range, and improves the product use performance.

[0020] 2. In the large numerical control beveling machine provided by the present utility model, the clamping pieces are detachably installed on the adjusting plate in a plug-and-play manner, and axial adjustment can be achieved by moving the adjusting plate along the X-axis direction, that is, the position of the clamping piece is adjusted to make way for and adapt to the position of the connecting pipe. During the clamping process of the steel pipe, the two groups of clamping piece assemblies can be used to clamp the steel pipe in a relative form or in a crossed form, which is equivalent to the fingers crossing and inserting towards each other, and the clamping effect is good. With this structural setting, the clamping mechanism clamps the steel pipe workpiece stably, positions accurately, and is easy to operate. In cooperation with the feeding and rotation of the cutter head mechanism in the X-axis direction, the bevel processing of the steel pipe workpiece can be accurately realized.

[0021] 3. In the large numerical control beveling machine provided by the present utility model, an arc-shaped or V-shaped clamping groove is arranged on the other side of the clamping piece, and the clamping opening is composed of a plurality of opposite clamping grooves. A buffer sleeve is arranged on the groove wall of the clamping groove. Since the clamping piece is in clamping contact with the steel pipe, the buffer sleeve can prevent the clamping piece from colliding with the steel pipe hard during the clamping process, causing damage to the steel pipe, and can relieve the impact force. During the processing process, the elastic deformation of the buffer sleeve is used to absorb and disperse the energy of mechanical vibration, so as to achieve the effects of shock absorption, vibration reduction, and vibration isolation.

[0022] 4. In the large CNC beveling machine provided by the present utility model, the mounting block is displaced and adjusted along the Z-axis direction through a height adjustment mechanism. The height adjustment structure adopts a driving and adjusting method using an oil cylinder structure, mainly including an oil cylinder body and a piston rod installed in the accommodation groove. The mounting table is fixed to the side wall of the oil cylinder body to achieve linkage cooperation. By providing two limiting plates connected to both ends of the piston rod in the accommodation groove, when hydraulic oil enters the oil cylinder, since both ends of the piston rod are fixed after being limited and the oil cylinder body is in a free state, under the action of the hydraulic pressure, the oil cylinder body makes a reciprocating movement along the axial direction of the piston rod, thereby synchronously driving the mounting table to make a linear movement in the Z-axis direction, and finally realizing the function of adjusting the height of the clamping piece assembly. This hydraulic cylinder adjustment method has the characteristics of simple structure, large output force, stable and reliable performance, convenient use and maintenance, etc. It also has accurate control ability, flexible installation and use, and convenient adjustment operation.

[0023] 5. In the large CNC beveling machine provided by the present utility model, since the steel pipe is very long and heavy, a support mechanism plays a role in supporting and positioning the steel pipe. This support mechanism mainly consists of a pulley base, two support seats, and two groups of inclined plate structures. The steel pipe is placed in the support opening formed by the two groups of inclined plate structures, and the distance between the two support seats is adjusted by moving to adjust the size of the support opening. The support opening and the clamping opening are arranged oppositely along the axial direction of the steel pipe, ensuring that one end of the steel pipe is clamped by the clamping piece in the clamping opening, so as to adapt to the support requirements of steel pipes of different sizes. By moving the pulley base along the third slide rail, one end of the steel pipe can be transferred to the position of the clamping opening, and then the steel pipe can be clamped by two groups of clamping piece assemblies. After the beveling processing of the steel pipe is completed, moving the pulley base can easily move the steel pipe outwards. In this way, the loading and unloading of the steel pipe are convenient, and the operation is simple, time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment

[0035] This embodiment provides a large-scale numerical control beveling machine as Figures 1-5 shown, which includes a tool head mechanism 2 and a clamping mechanism arranged on the frame 1. The clamping mechanism is provided with a clamping port for clamping the steel pipe 9. The tool head mechanism 2 moves along the X-axis direction towards or away from one end of the steel pipe. The clamping mechanism includes:

[0036] Two driving platforms 3 are arranged on the frame 1 to move relatively along the Y-axis direction;

[0037] Two adjusting plates 4 are arranged opposite to the two driving platforms 3 and are respectively movable and adjustable in position along the X-axis direction;

[0038] Two groups of clamping piece assemblies 5 are respectively detachably inserted into the two adjusting plates 4. The clamping openings are formed between the two groups of clamping piece assemblies 5. When the two driving platforms 3 move towards each other, they drive the two groups of clamping piece assemblies 5 to clamp the steel pipe 9. Each group of the clamping piece assemblies 5 includes a plurality of clamping pieces 51 arranged at intervals along the X-axis direction on the adjusting plate 4, and a plurality of partition grooves 52 formed between the plurality of clamping pieces 51, so that a plurality of connecting pipes 91 arranged at intervals on the side wall of one end of the steel pipe 9 are respectively received in the plurality of partition grooves 52.

[0039] The above-mentioned embodiment is the core technical solution of this embodiment. By respectively inserting two groups of clamping piece assemblies 5 on the two adjusting plates 4, and each group of clamping piece assemblies 5 includes a plurality of clamping pieces 51 arranged at intervals on the adjusting plate 4, and a plurality of partition grooves 52 are formed between the plurality of clamping pieces 51. The advantage of such a design is that during operation, the two driving platforms 3 move towards each other to drive the two groups of clamping piece assemblies 5 to clamp the steel pipe 9, and at the same time, a plurality of connecting pipes 91 arranged at intervals on the side wall of one end of the steel pipe 9 are respectively received in the plurality of partition grooves 52. The plurality of partition grooves 52 are exactly adapted to the positions of the plurality of connecting pipes 91. Even in the case of position interference between the connecting pipes 91 and the clamping pieces 51, the position relationship between the clamping pieces 51 and the connecting pipes 91 can be adaptively adjusted by moving the adjusting plate 4, or a certain clamping piece 51 can be removed to make way for the connecting pipe 91, so as to ensure that the clamping mechanism clamps the steel pipe while avoiding the situation of position interference between the clamping pieces 51 and the connecting pipes 91. Finally, as long as the steel pipe is processed by the cutter head mechanism for automatic beveling, the performance is stable, and the smoothness and bevel accuracy of the bevel processing surface are guaranteed. The clamping mechanism adopted by this beveling machine can meet the processing and use requirements of steel pipe products with connecting pipes, has a wide application range, and improves the product use performance.

[0040] The following will be combined with Figures 1-3 Make a detailed description of the specific setting method of the clamping mechanism:

[0041] A plurality of mounting slots are provided on the adjusting plate 4 at intervals. One side of the clamping piece 51 is provided with a mounting plug block that is inserted into the mounting slot in a matching manner. The cross-sectional shapes of the mounting slot and the mounting plug block are both T-shaped structures. The two sets of clip assemblies 5 clamp the steel pipe 9 in an opposite manner in a relative form or in an opposite manner in a crossed form. With this structural arrangement, the clamping piece 51 is detachably mounted on the adjusting plate 4 by means of a plug-in method, and axial adjustment can be achieved by moving the adjusting plate 4 along the X-axis direction, that is, by adjusting the position of the clamping piece 51 to make way for and adapt to the position of the connecting pipe 91. During the clamping process of the steel pipe 9, the two sets of clip assemblies 5 can be used to clamp the steel pipe 9 in an opposite manner in a relative form or in an opposite manner in a crossed form, which is equivalent to inserting the fingers in a crossed manner. The clamping effect is good, the clamping of the steel pipe 9 workpiece by the clamping mechanism is stable, the positioning is accurate, the operation is simple, and in cooperation with the feeding and rotation of the cutter head mechanism 2 in the X-axis direction, the bevel processing of the steel pipe workpiece can be accurately achieved.

[0042] The clamping opening includes a clamping groove 53 provided on the other side of the clamping piece 51 and having an arc shape or a V shape. A buffer sleeve 54 is provided on the groove wall of the clamping groove 53. It can be seen that the clamping opening is composed of a plurality of opposite clamping grooves 53. Since the clamping piece 51 is in contact with the steel pipe 9 for clamping, the buffer sleeve 54 can prevent the clamping piece 51 from colliding with the steel pipe 9 hard during the clamping process, resulting in damage to the steel pipe 9, and can relieve the impact force. During the processing process, the elastic deformation of the buffer sleeve 54 is used to absorb and disperse the energy of mechanical vibration, so as to achieve the effects of vibration reduction and vibration isolation.

[0043] Combined Figure 1 and Figure 4 As shown, the machine frame 1 is provided with a first slide rail 11 extending along the Y-axis direction. An installation cavity extending in the same direction as the first slide rail 11 is provided in the first slide rail 11. The two driving platforms 3 respectively include two first sliding seats 31 slidably connected to the first slide rail 11. A moving connection is formed between the two driving platforms 3 through a lead screw structure. The lead screw structure includes a lead screw shaft 32 rotatably provided in the installation cavity, two nut seats 33 respectively provided at the bottoms of the two first sliding seats 31 and threadedly connected to the lead screw shaft 32, and a coupling 34 connected to one end of the lead screw shaft. The coupling 34 is connected to a motor or a cylinder, so as to drive the lead screw shaft to rotate, and under the action of the thread, drive the two driving platforms 3 to drive the two sets of clip assemblies 5 to approach or move away from each other, so as to realize the clamping or loosening operation of the steel pipe.

[0044] Further preferably, two T-shaped chutes 30 extending in the X-axis direction are respectively arranged on one side of the two driving platforms 3 facing each other. Two adjusting plates 4 are respectively provided with T-shaped sliders that are slidably connected to the T-shaped chutes 30. Through the cooperation of the T-shaped chutes 30 and the T-shaped sliders, the adjusting plate 4 can freely move and adjust its position relative to the driving platform 3 along the X-axis direction. Specifically, the two driving platforms 3 respectively include two mounting blocks connected to the two adjusting plates 4, and the two T-shaped chutes 30 are respectively arranged oppositely on the two mounting blocks, that is, the adjusting plate 4 is slidably connected to the mounting block. Among them, a height adjusting mechanism for driving the mounting block to move along the Z-axis direction is arranged on the driving platform 3. Such a design enables the mounting block to perform displacement adjustment along the Z-axis direction through the height adjusting mechanism, thereby realizing the height adjustment of the clamping piece assembly, so that steel pipes at different height positions can be adaptively clamped, and the application range is wider.

[0045] As a preferred embodiment, as Figures 3-4 shown, the height adjusting structure 7 is an oil cylinder structure arranged on the driving platform 3, which includes an oil cylinder body 72 and a piston rod 71 movably penetrating through the oil cylinder body 72. A receiving groove 35 suitable for accommodating the oil cylinder body 72 and the piston rod 71 is provided in the driving platform 3. Two limiting plates 73 are arranged oppositely up and down in the receiving groove 35. The mounting block is fixedly connected to the outer wall of the oil cylinder body 72. The two ends of the piston rod 71 extending out of the oil cylinder body 72 are respectively limited and connected to the two limiting plates 73, so that the oil cylinder body 72 makes a reciprocating movement along the axial direction of the piston rod 71 when driven. The axial direction of the piston rod 71 is consistent with the Z-axis direction. The advantage of such a design is that according to the driving and adjusting method of the oil cylinder structure for the height adjusting structure 7, the oil cylinder body 72 and the piston rod 71 are relatively movable. By providing two limiting plates 73 connected to both ends of the piston rod 71 in the receiving groove 35, when hydraulic oil enters the oil cylinder, since both ends of the piston rod 71 are limited and remain stationary, while the oil cylinder body 72 is in a free state, under the action of the hydraulic pressure, the oil cylinder body 72 makes a reciprocating movement along the axial direction of the piston rod 71, thereby synchronously driving the mounting platform 6 to perform a linear movement in the Z-axis direction, and finally realizing the function of adjusting the height of the clamping piece assembly 5. This hydraulic cylinder adjusting method has the characteristics of simple structure, large output force, stable and reliable performance, convenient use and maintenance, etc., and also has accurate control ability, flexible installation and use, and convenient adjustment operation.

[0046] The following will combine Figures 1-3 to elaborate in detail on the specific setting method of the tool head mechanism 2:

[0047] The frame 1 is provided with a second slide rail 21 extending in the X-axis direction. The bottom of the tool head mechanism 2 is provided with a second slide block 22 slidably connected to the second slide rail 21. The tool head mechanism 2 includes a driving main shaft 23 rotatably arranged, a tool assembly 24 linked to one end of the driving main shaft 23, and a tool head motor 25 connected to the other end of the driving main shaft 23. The tool head motor 25 is a servo motor and is in transmission connection with the driving main shaft 23 through a transmission belt. The tool assembly 24 includes a tool holder fixedly connected to one end of the driving main shaft 23 and a tool body slidably arranged on the tool holder. One end of the tool body faces the steel pipe 9. During processing, the tool head structure drives the tool assembly 24 to move close to one end of the steel pipe 9 in the X-axis direction, and then the tool head motor 25 drives the tool assembly 24 to perform a rotational motion, thereby completing the groove machining task of the steel pipe workpiece.

[0048] The large numerical control beveling machine provided in this embodiment further includes a third slide rail 81 extending in the X-axis direction and arranged on one side of the clamping mechanism, and at least one support mechanism 8 slidably arranged on the third slide rail 81, so that the steel pipe 9 abuts against the support mechanism 8. Specifically, the support mechanism 8 includes a pulley base 82 slidably connected to the third slide rail 81 and two support seats 83 relatively movably arranged on the pulley base 82. Two groups of inclined plate structures 84 are oppositely arranged on the two support seats 83, and a support opening opposite to the clamping opening is formed between the two groups of inclined plate structures 84. With this structural arrangement, since the steel pipe 9 is very long and heavy, the support mechanism 8 plays a role in supporting and positioning the steel pipe 9. This support mechanism 8 is mainly composed of a pulley base 82, two support seats 83 and two groups of inclined plate structures 84. The steel pipe 9 is placed in the support opening formed by the two groups of inclined plate structures 84, and the distance between the two support seats 83 is adjusted to adjust the size of the support opening. The support opening and the clamping opening are arranged oppositely along the axial direction of the steel pipe 9, ensuring that one end of the steel pipe 9 is clamped by the clamping piece 51 in the clamping opening, so as to adapt to the support requirements of steel pipes 9 of different sizes. By moving the pulley base 82 along the third slide rail 81, one end of the steel pipe 9 can be moved to the clamping opening position, and then the steel pipe 9 can be clamped by the two groups of clamping piece assemblies 5. After the groove machining of the steel pipe 9 is completed, moving the pulley base 82 can easily move the steel pipe 9 outwards. In this way, the loading and unloading of the steel pipe 9 are convenient, and the operation is simple, time-saving and labor-saving. It should be noted that the X-axis direction, Y-axis direction and Z-axis direction in this article correspond to the three coordinate axis directions of the space rectangular coordinate system, and the X, Y, and Z axis coordinate directions are pointed out in Figure 1 It can be clearly known that the axial direction of the steel pipe is parallel to the X-axis direction, the axial direction of the lead screw shaft is parallel to the Y-axis direction, and the axial direction of the piston shaft is parallel to the Z-axis direction, so that the movement directions of each mechanism and component can be clearly understood.

[0049] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
