Description

Technical Field

[0001] This utility model relates to the field of long shaft workpiece processing technology, and in particular to a long shaft workpiece processing feed device. Background Technology

[0002] The piston rod is a core moving component of a marine diesel engine. It is relatively long and difficult to machine. Currently, the piston rod is mainly machined by boring machines to drill and mill both ends. During the machining process, the piston rod needs to be moved axially or rotated circumferentially. These processes are currently mainly completed manually, which is time-consuming, labor-intensive, and poses significant safety hazards.

[0003] To address this, a piston rod rotation device has been provided. During machining, the piston rod is supported by a V-block. After completing one machining step, the rotation device lifts the piston rod, disengaging it from the V-block. After rotating the piston rod circumferentially by a certain angle, it is lowered back onto the V-block for continued machining at the next step, thus enabling multi-faceted machining of the piston rod. However, this rotation device only addresses the rotation of the piston rod; axial movement still requires manual operation. Utility Model Content

The first lead screw includes a forward thread section and a reverse thread section arranged sequentially along the first direction.

[0014] Two clamping blocks are slidably disposed on the base of the clamping assembly along a first direction, and the two clamping blocks are respectively threadedly connected to the forward thread segment and the reverse thread segment;

[0015] A first motor is mounted on the base of the clamping assembly and is used to drive the first lead screw to rotate, thereby causing the two clamping blocks to move closer to or further apart from each other.

[0021] A lifting drive is used to drive the rolling support assembly to move up and down in the vertical direction, so that the rolling support assembly has an initial position and a raised position. When the rolling support assembly is in the initial position, the long shaft workpiece is supported by the support block, and the rollers of each of the roller groups are separated from the long shaft workpiece. When the rolling support assembly is in the raised position, the rollers of the two roller groups are spaced apart and supported on both sides of the long shaft workpiece, so that the long shaft workpiece is separated from the support block.

[0040] The piston rod is primarily machined using a boring machine to drill and mill both ends. During machining, the piston rod needs to be moved axially or rotated circumferentially, processes currently mainly performed manually. To address this, a piston rod rotation device has been developed. During machining, the piston rod is supported by a V-block. After completing one machining step, the device lifts the piston rod, disengaging it from the V-block. After rotating the piston rod circumferentially by a certain angle, it is lowered back onto the V-block for continued machining at the next step, thus enabling multi-faceted machining of the piston rod. However, this rotation device only addresses the rotation requirement; axial movement of the piston rod still requires manual operation.

[0041] In response, this embodiment provides a feeding device for machining long shaft workpieces to solve the problem that the axial movement of the piston rod still needs to be manually operated in the prior art, and can be used in the field of machining long shaft workpieces.

[0042] Reference Figure 1 The long shaft workpiece machining feed device includes a base 1, a clamping assembly 3, an axial feed drive assembly, and multiple support mechanisms. Each support mechanism includes a support block 2 for supporting the long shaft workpiece. These multiple support mechanisms are spaced apart along the axial direction of the long shaft workpiece, providing stable support along its axial direction. The long shaft workpiece is placed horizontally, with its axis parallel to the horizontal plane. The clamping assembly 3 is located on the base 1 and is used to clamp or release the long shaft workpiece. The axial feed drive assembly is also located on the base 1 and drives the clamping assembly 3 to move along the axial direction of the long shaft workpiece. Thus, when the clamping assembly 3 clamps the long shaft workpiece, the axial feed drive assembly can move the clamping assembly 3 along the axial direction of the long shaft workpiece, thereby moving the long shaft workpiece along its axial direction without requiring manual movement. Specifically, the long shaft workpiece is a marine diesel engine piston rod; alternatively, it can be other long shaft workpieces. The axial direction of the long shaft workpiece is... Figure 1 In the AB direction.

[0043] Continue to refer to Figure 1 The clamping assembly 3 includes a clamping assembly base 31, a first lead screw, a first motor 33, and two clamping blocks 32. The clamping assembly base 31 is slidably mounted on the base 1 along the axial direction of the long shaft-like workpiece. The axial feed drive assembly is used to drive the clamping assembly base 31 to move. The first lead screw is rotatably mounted on the clamping assembly base 31. The centerline of the first lead screw extends along a first direction, which is perpendicular to the axial direction of the long shaft-like workpiece. The first lead screw includes a forward thread section and a reverse thread section arranged sequentially along the first direction, which is perpendicular to the axial direction of the long shaft-like workpiece. The first direction is... Figure 1The two clamping blocks 32 are located on both sides of the long shaft workpiece, respectively. Both clamping blocks 32 are slidably mounted on the clamping assembly base 31 along the first direction, and are threadedly connected to the forward thread section and the reverse thread section, respectively. Specifically, the clamping assembly base 31 is provided with a sliding groove 311, and both clamping blocks 32 are slidably mounted within the sliding groove 311. When the first lead screw rotates, the two clamping blocks 32 can move closer to or further away from each other. The first motor 33 is mounted on the clamping assembly base 31 and is used to drive the first lead screw to rotate, thereby causing the two clamping blocks 32 to move closer to or further away from each other, thus achieving clamping or releasing the long shaft workpiece. Optionally, a reducer is also provided between the first motor 33 and the first lead screw.

[0044] Continue to refer to Figure 1 The axial feed drive assembly includes a second lead screw rotatably connected to the base 1 and a second motor disposed on the base 1. Specifically, the base 1 has a lead screw receiving groove 11, the second lead screw is disposed in the lead screw receiving groove 11, the second lead screw extends along the axial direction of the long shaft workpiece, the clamping assembly base 31 is threadedly connected to the second lead screw, and the second motor is used to drive the second lead screw to rotate, thereby driving the clamping assembly base 31 to move along the axial direction of the long shaft workpiece. The second lead screw can be a trapezoidal lead screw.

[0045] Continue to refer to Figure 1 The base 1 is also provided with a guide rail, which extends along the axial direction of the long shaft workpiece. The clamping component base 31 is slidably disposed on the guide rail, so that the movement of the clamping component base 31 can be guided by the guide rail.

[0046] Continue to refer to Figure 1 Multiple support blocks 2 are V-shaped, and each support block 2 has two support surfaces 21 set at an angle. The two support surfaces 21 are used to support long shaft workpieces at the same time, so that the long shaft workpiece can be stably placed above the two support surfaces 21. After placement, there will be no relative displacement between the two.

[0047] Continue to refer to Figure 1The support mechanism also includes a rotary drive assembly, which comprises a rolling support assembly and a lifting drive component. The rolling support assembly includes two roller groups 4, spaced apart. Each roller group 4 includes a roller 41 and a motor connected to the roller 41 for transmission. The motor drives the roller 41 to rotate, and the rotation center line of the roller 41 is parallel to the axial direction of the long shaft-like workpiece. The lifting drive component drives the rolling support assembly to move vertically, giving the rolling support assembly an initial position and a raised position. When the rolling support assembly is in the initial position, the long shaft-like workpiece is supported on the support block 2, and the rollers 41 of each roller group 4 are separated from the long shaft-like workpiece. When the rolling support assembly is in the raised position, the rollers 41 of the two roller groups 4 are spaced apart and support the long shaft-like workpiece on both sides, separating the long shaft-like workpiece from the support block 2. The vertical direction is... Figure 1 In the EF direction, the first direction and the axial direction of the long-axis workpiece are perpendicular to each other with the vertical direction. By setting up rolling support components and lifting drive components, when it is necessary to adjust the rotation angle of the long-axis workpiece, the rolling support components can be driven to the lifting position by the lifting drive components. At this time, the long-axis workpiece is no longer in contact with the support block 2. The long-axis workpiece can be leveled along its axial direction by using a spirit level or lever. After leveling, the roller 41 can be driven to rotate by the motor to drive the long-axis workpiece to rotate. After the angle adjustment is completed, the rolling support components are driven back to the initial position by the lifting drive components, so that the long-axis workpiece is supported by the support block 2 again. Optionally, one lifting drive component can be set up to drive the movement of two rolling support components at the same time. In addition, two lifting drive components can be set up, with each of the two lifting drive components corresponding to one of the two rolling support components.

[0048] The roller 41 and the motor can be integrated or separate. In this embodiment, the motor and roller 41 in the roller assembly 4 are integrated.

[0049] Continue to refer to Figure 1 The two support surfaces 21 of the support block 2 are provided with receiving grooves 211. The two roller groups 4 of the rolling support assembly are movably arranged in the two 211 in a one-to-one correspondence. When the rolling support assembly is in the initial position, each roller group 4 is stored in the corresponding receiving groove 211. When the rolling support assembly is in the lifting position, the roller 41 of each roller group 4 extends out of the corresponding receiving groove 211. Thus, when the rolling support assembly is not in use, the roller 41 of the roller group 4 can be stored in the receiving groove 211, which can save installation space and make the structure more compact.

[0050] Continue to refer to Figure 1The support mechanism also includes a locking structure 5, which can press the long shaft workpiece against the support block 2 or separate it from the long shaft workpiece. Thus, when processing the long shaft workpiece, the locking structure 5 can press the long shaft workpiece against the support block 2 to lock the long shaft workpiece, making processing easier. When the position of the long shaft workpiece needs to be adjusted after processing at one position, the locking structure 5 separates from the long shaft workpiece to release the lock.

[0051] Specifically, the locking structure 5 includes a mounting block 51 located above the support block 2 and a locking member threadedly connected to the mounting block 51. In this embodiment, the locking member is specifically a locking screw. The locking member is used to press the long shaft-type workpiece against the support block 2 to lock the long shaft-type workpiece. In addition, the locking member can be released by turning it in the opposite direction. Optionally, the mounting block 51 is fixedly mounted on the support block 2 by two fixing rods 52.

[0052] The following combination Figure 1 The operation process of the long shaft workpiece machining feed device in this embodiment is introduced.

[0053] The long shaft workpiece is hoisted onto the support block 2 by the hoisting device. The long shaft workpiece is supported by multiple support blocks 2 and clamped by the locking parts on the mounting block 51, ready for processing.

[0054] If the angle of a long-shaft workpiece needs to be adjusted, first loosen the locking device on mounting block 51, and drive the rolling support assembly to the raised position using the lifting drive. At this point, the long-shaft workpiece is no longer in contact with support block 2. The long-shaft workpiece can be leveled along its axial direction using a spirit level or dial indicator. After leveling, the roller 41 can be rotated using the rotating drive to rotate the long-shaft workpiece. After the angle adjustment is complete, drive the rolling support assembly back to its initial position using the lifting drive, so that the long-shaft workpiece is supported by support block 2 again. Then, clamp it again using the locking device on mounting block 51, ready for processing.

[0055] During processing, the locking element on the mounting block 51 is kept loose, the long shaft workpiece is clamped by the clamping assembly 3, and the clamping assembly 3 is driven by the axial feed drive assembly to move along the axial direction of the long shaft workpiece, so as to move the long shaft workpiece along its axial direction and adjust the axial position of the long shaft workpiece. Then, the long shaft workpiece is pressed against the support block 2 by the locking element to lock the long shaft workpiece. After the long shaft workpiece is locked, processing can begin.

[0056] After machining one position of a long shaft workpiece, if machining the next position requires adjusting the axial position or rotation angle of the long shaft workpiece, the locking structure 5 can be operated to separate it from the long shaft workpiece, release the lock, and control the two clamping blocks 32 of the clamping assembly 3 to move away from each other, releasing the clamping of the long shaft workpiece. The angle of the long shaft workpiece can then be adjusted again by operating the lifting drive and the rotation drive. Subsequently, the long shaft workpiece is clamped again by the clamping assembly 3, and the long shaft workpiece is moved by the axial feed drive assembly. The locking structure 5 locks the long shaft workpiece, and subsequent machining operations can then be performed.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
