Description

Technical Field

[0001] This utility model relates to the field of drill pipe processing technology, and in particular to a device for adjusting the axial position of pipe material. Background Technology

[0002] In existing technologies, drill rod machining typically employs a single-end machining method, where a single-head machine tool processes one end before turning to machine the other. This requires the loading mechanism to align both ends simultaneously. While the alignment device is simple in structure and easy to operate, subsequent single-end machining requires secondary adjustment of the drill rod, resulting in low efficiency. To address this, a method using a double-head machine tool to simultaneously machine both ends of the drill rod has emerged. Double-head machine tool machining requires the drill rod to be centered axially to facilitate simultaneous machining of both ends. However, existing drill rod loading devices can only align one end of the drill rod after loading, which clearly cannot meet the machining requirements of a double-head machine tool. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tube axial position centering adjustment device, which aims to meet the processing requirements of a double-head machine tool and avoid adjusting the position of the tube during the processing of the double-head machine tool.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A pipe axial position centering adjustment device includes:

[0006] The storage rack is inclined and is used to store tubular materials and move them downwards in the feeding direction;

[0007] A material blocking mechanism is provided on the upper part of the storage rack to prevent the tubular material from stacking during downward movement;

[0008] A limiting mechanism is provided at the discharge end of the storage rack to block the tube material located at the bottom.

[0009] A lifting mechanism is used to lift the lowest tube to the transition plate;

[0010] The transition plate is inclined to guide the lowest tube to roll down to the material support mechanism;

[0011] The centering alignment mechanism includes a power mechanism and two sets of clamping mechanisms arranged opposite to each other. The two sets of clamping mechanisms are driven by the power mechanism to move synchronously and push the tube on the material support mechanism from both ends of the axis until both ends of the tube are clamped by the two sets of clamping mechanisms at the same time, so as to achieve axial centering.

[0012] The further technical solution is as follows:

[0013] The clamping mechanism includes a fixed frame, on which a guide block, a baffle, and a limit switch are provided. The guide block and the baffle are connected by studs.

[0014] A guide post is slidably disposed in the guide block and the baffle. One end of the guide post extends out of the guide block and is connected to the push block. A spring is sleeved on the guide post, and its two ends abut against the guide block and the baffle respectively. The other end of the guide post is used to trigger the limit switch.

[0015] The structure of the material support mechanism includes a plurality of V-shaped support blocks arranged at intervals, and the V-shaped surfaces of the plurality of V-shaped support blocks form a horizontal support surface.

[0016] The installation height of the bottom of the push block is lower than the installation height of the V-shaped surface.

[0017] The structure of the power mechanism includes a linear drive component, which is mounted on a horizontal frame. The horizontal frame has a first guide rail and a second guide rail that are parallel to each other on both sides in the width direction, and a transmission gear is provided between the first guide rail and the second guide rail.

[0018] A first slide plate is slidably connected to the first guide rail, and a first rack parallel to the first guide rail is provided thereon. A second slide plate is slidably connected to the second guide rail, and a second rack parallel to the second guide rail is provided thereon. The first rack and the second rack mesh synchronously with the transmission gear.

[0019] The output end of the linear drive is connected to the first or second sliding plate.

[0020] The limiting mechanism includes several limiting components arranged at intervals;

[0021] The limiting component includes an adjusting element and a pad;

[0022] The pad is mounted on the support column of the storage rack via the adjusting member. The adjusting member is used to adjust the position of the pad along the feeding direction, and the outer side of the pad is used to contact the tube material.

[0023] The lifting mechanism includes several lifting plates arranged at intervals, which move up and down under the drive of the lifting power component;

[0024] A placement position is formed between the upper end face of the lifting plate and the outer side face of the pad block. The position of the pad block is adjusted so that the placement position can accommodate and only accommodate the lowermost pipe.

[0025] The adjusting member is provided with a plurality of mounting holes distributed along the feeding direction, and the mounting holes are used to connect to the supporting column through a locking member.

[0026] The lifting power assembly includes a lifting cylinder, a drive shaft, a linear bearing mounted on the support column, and a lifting guide rod that cooperates with the linear bearing.

[0027] The drive shaft is fitted with a drive fork and several driven forks. The output end of the lifting cylinder is hinged to the end of the drive fork. The driven forks are hinged to the bottom end of the lifting guide rod. The top end of the lifting guide rod is connected to the lifting plate.

[0028] The structure of the material blocking mechanism includes a rotating shaft and at least one stop rod disposed on the rotating shaft;

[0029] One end of the rotating shaft is connected to the drive motor, and the other end is connected to the bearing housing. The drive motor and the bearing housing are mounted on the support frame, which is located above the storage rack.

[0030] The rotating shaft is driven to rotate by the drive motor to adjust the distance between the end of the stop bar and the storage rack.

[0031] The beneficial effects of this utility model are as follows:

[0032] This invention realizes automatic material blocking, material feeding, and axial centering adjustment, providing a precise positioning reference for the subsequent synchronous processing of both ends of the tube by a double-head machine tool, thereby ensuring processing accuracy and improving processing efficiency.

[0033] The centering positioning mechanism of this utility model has a precise positioning function. Regardless of the axial dimension or axial position of the incoming material, the axial position of any tube material can be centered by the synchronous movement of two sets of clamping mechanisms and the simultaneous triggering control of the limit switches of the two sets of clamping mechanisms.

[0034] The material blocking mechanism of this utility model can avoid material stacking and ensure that the pipes roll down one by one to the subsequent lifting mechanism and material support mechanism.

[0044] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0045] like Figure 1 , Figure 2 As shown, the pipe axial position centering adjustment device of this embodiment includes:

[0046] The storage rack 7 is inclined and is used to store the pipe material 5 and move it downward in the feeding direction;

[0047] The material blocking mechanism 6 is located on the upper part of the storage rack 7 to prevent the pipe material 5 from stacking during downward movement;

[0048] The limiting mechanism 4 is installed at the discharge end of the storage rack 7 to block the tube 5 located at the bottom.

[0049] Lifting mechanism 8, which is used to lift the lowest pipe 5 to the transition plate 3;

[0050] The transition plate 3 is inclined to guide the lowest pipe 5 to roll down to the material support mechanism 2;

[0051] The centering alignment mechanism includes a power mechanism and two sets of clamping mechanisms 1 arranged opposite to each other. The two sets of clamping mechanisms 1 are driven by the power mechanism to move synchronously and push the pipe material 5 on the material support mechanism 2 from both ends of the axial direction until both ends of the pipe material 5 are clamped by the two sets of clamping mechanisms 1 at the same time, so as to achieve axial centering.

[0052] As a preferred method, such as Figure 3 As shown, the clamping mechanism 1 includes a fixed frame 101, on which a guide block 108, a baffle 106 and a limit switch 107 are provided. The guide block 108 and the baffle 106 are connected by a stud 105. A guide post 103 is slidably disposed between the guide block 108 and the baffle 106. One end of the guide post 103 extends out of the guide block 108 and is connected to the push block 102. A spring 104 is sleeved on the guide post 103, and its two ends abut against the guide block 108 and the baffle 106 respectively. The other end of the guide post 103 is used to trigger the limit switch 107.

[0053] In this embodiment, the pipe material 5 can be a drill rod. Before the drill rod is processed, the two sets of clamping mechanisms 1 of the centering alignment mechanism move synchronously towards each other under the drive of the power mechanism until the limit switches 107 of both clamping mechanisms 1 are triggered. At this time, the push blocks 102 of the two clamping mechanisms 1 contact the two ends of the drill rod on the material support mechanism 2, and the axial position of the drill rod is adjusted to the center. Then, the two sets of clamping mechanisms 1 move synchronously in opposite directions under the drive of the power mechanism, disengaging from the end of the drill rod. At this time, the guide post 103 moves in opposite directions under the action of the restoring force of the spring 104, causing the push block 102 to return to the initial position. Then the power mechanism continues to drive until the clamping mechanism 1 returns to the initial position, preparing for the clamping and centering of the next drill rod. The centered drill rod can be transported by a transfer mechanism, such as a gantry machine, to the machining station of a double-headed lathe. The double-headed lathe can then directly machine both ends of the drill rod. Because the drill rod is centered axially, meaning each end is equidistant from the corresponding lathe, the feed rate of the double-headed lathe is identical, facilitating synchronous machining without the need to adjust the axial distance of the drill rod.

[0054] It is understandable that during the centering adjustment process, when one of the clamping mechanisms 1 contacts the end of the pipe, its limit switch is triggered, but the other clamping mechanism 1 does not contact the end of the pipe. At this time, the power mechanism drives the two clamping mechanisms 1 to continue moving until both clamping mechanisms 1 contact the end of the pipe, that is, both limit switches are triggered, and the power mechanism stops driving, thus completing the centering adjustment.

[0055] As a preferred method, see Figure 1 and Figure 2 The structure of the material support mechanism 2 includes several V-shaped support blocks 201 arranged at intervals, and the V-shaped surfaces of the several V-shaped support blocks 201 constitute a horizontal support surface.

[0056] As a preferred embodiment, the mounting height of the bottom of the pusher block 102 is lower than the mounting height of the V-shaped surface, to accommodate clamping of pipes with different axial dimensions.

[0057] As a preferred method, see Figure 4 and Figure 5 The structure of the power mechanism includes a linear drive component 12, which is mounted on a horizontal frame 9. The horizontal frame 9 has a first guide rail 16 and a second guide rail 18 that are parallel to each other on both sides in the width direction. A transmission gear 15 is provided between the first guide rail 16 and the second guide rail 18.

[0058] The first slide plate 13 is slidably connected to the first guide rail 16, and a first rack 14 parallel to the first guide rail 16 is provided thereon. The second slide plate 19 is slidably connected to the second guide rail 18, and a second rack 17 parallel to the second guide rail 18 is provided thereon. The first rack 14 and the second rack 17 mesh synchronously with the transmission gear 15.

[0059] The output end of the linear drive 12 is connected to the first slide plate 13 or the second slide plate 19.

[0060] The linear drive component 12 is preferably a cylinder.

[0061] As a preferred method, see Figure 6 and Figure 7 The limiting mechanism 4 includes several limiting components arranged at intervals;

[0062] The limiting component includes an adjusting element 42 and a pad 41;

[0063] The pad 41 is installed on the support column 71 of the storage rack 7 via the adjusting member 42. The adjusting member 42 is used to adjust the position of the pad 41 along the feeding direction. The outer side of the pad 41 is used to contact the tube 5.

[0064] The lifting mechanism 8 includes several lifting plates 81 arranged at intervals, which move up and down under the drive of the lifting power component;

[0065] The upper end face of the lifting plate 81 and the outer side of the pad 41 form a placement position. The position of the pad 41 is adjusted so that the placement position can accommodate and only accommodate the bottommost pipe 5.

[0066] By adjusting the position of the pad 41, the width of the placement position can be adjusted to meet the placement requirements of pipes with different radial dimensions.

[0067] As a preferred embodiment, the adjusting member 42 is provided with a plurality of mounting holes 43 distributed along the feeding direction. The mounting holes 43 are used to connect to the support column 71 via locking members. Different mounting holes 43 on the adjusting member 42 are locked to the support column 71 via locking members, allowing the position of the adjustable pad 41 to be adjusted backwards. Figure 7As indicated by the middle arrow, the placement position can be decreased, and vice versa, the placement position can be increased.

[0068] As a preferred method, see Figure 6 The lifting power assembly includes a lifting cylinder 87, a drive shaft 85, a linear bearing 82 mounted on a support column 71, and a lifting guide rod 83 that cooperates with the linear bearing 82.

[0069] The drive shaft 85 is fitted with a drive fork 86 and several driven forks 84. The output end of the lifting cylinder 87 is hinged to the end of the drive fork 86, the driven forks 84 are hinged to the bottom end of the lifting guide rod 83, and the top end of the lifting guide rod 83 is connected to the lifting plate 81.

[0070] As a specific implementation method, a bracket 10 is provided on the support column 71.

[0071] The brackets 10 on each supporting column 71 constitute the mounting positions for the material support mechanism 2. (See also...) Figure 2 Each V-shaped support block 201 of the material support mechanism 2 is mounted on a horizontal support plate 202, and the horizontal support plate 202 is mounted on the bracket 10.

[0072] As a specific implementation, a bracket 2 11 is provided on the support column 71.

[0073] The brackets 11 on each supporting column 71 constitute the mounting positions for the centering alignment mechanism. (See also...) Figure 2 The horizontal frame 9 of the centering alignment mechanism is mounted on the second bracket 11.

[0074] In a specific implementation, the transition plate 3 is set on the top of the support column 71 and is inclined downward along the feeding direction.

[0075] As a preferred method, see Figure 1 The structure of the material blocking mechanism 6 includes a rotating shaft 62 and at least one stop bar 61 provided on the rotating shaft 62;

[0076] One end of the rotating shaft 62 is connected to the drive motor 63, and the other end is connected to the bearing housing. The drive motor 63 and the bearing housing are mounted on the support frame 60, which is positioned above the storage rack 7.

[0077] The rotating shaft 62 is driven to rotate by the drive motor 63 to adjust the distance between the end of the stop lever 61 and the storage rack 7. This distance allows only one tube to pass through at a time, preventing tube accumulation. Furthermore, since this distance is adjustable, it can meet the material-stopping requirements of tubes with different radial dimensions.

[0078] The tube axial position centering adjustment device in this embodiment realizes automatic material blocking, material feeding, and axial centering adjustment, providing a precise positioning reference for the subsequent synchronous processing of both ends of the tube by the dual-head machine tool, thereby improving efficiency.
