Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a straight Y-axis hard rail car milling pin turret mechanism. Background Art

[0002] The tool turret is an important accessory for high-precision CNC machine tools. It is generally loaded with various types of tools such as turning, milling, and drilling, and can quickly switch between different tools through rotation. In actual applications, the tool turret is directly fixed to the lathe / milling machine or loaded onto the movable part of the lathe / milling machine. When it is directly fixed, it only has the ability to rotate and has poor ability to compensate for radial movement. When it moves with the help of movable parts, the tool disc of the tool turret is far away from the actual sliding track, with poor stability and corresponding low compensation accuracy. In addition, the tool turret is not stable and lacks precision when adjusting the milling position, which can easily affect the milling accuracy.

[0003] In order to solve the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a high-stability power turret [CN202320901695.5], which includes a base body, a carrier cavity is provided through the base body, a tailstock is provided through the carrier cavity, a cutter disc fixed to the end of the tailstock, and a lifting plate fixed to the tailstock or integrally formed with the tailstock; at least two sliders are fixed to the end of the lifting plate facing away from the cutter disc, at least two slide rails are fixed to one end of the base body, an extension is provided on the end of the base body located between the two sliders, a screw rod is provided through the extension rod to drive the tailstock to move along the slide rail, and a first drive mechanism is provided on the base body to drive the screw rod to rotate; the vertical distance between the rotation center of the screw rod and the cutter disc is less than or equal to the vertical distance between the slide rail and the cutter disc; thereby, the cutter disc can be closer to the sliding track, which improves stability, and also reduces the swing torque between the slider and the slide rail, reduces the wear between the slider and the slide rail, and maintains the accuracy of the turret.

[0004] The above solution solves to a certain extent the problem of poor radial movement compensation capability of the turret in the existing technology, which affects stability. However, the solution still has many shortcomings, for example: the turret has poor stability and insufficient accuracy when raising and lowering the milling position, which easily affects the milling accuracy.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, a straight Y-axis hard rail car milling pin turret mechanism includes an assembly frame 1, a turret lifting seat 11 is provided in the assembly frame 1, one end of the turret lifting seat 11 is connected to a turret 12 arranged outside the assembly frame 1, and the other end is provided with a turret drive motor 13 for driving the turret 12 to rotate, a lifting control component 2 is provided on the turret lifting seat 11, and the lifting control component 2 is driven by a linkage drive structure 3, the turret lifting seat 11 is provided with a lifting deceleration component 4, and a lifting guide component 5 is provided at the end of the assembly block away from the turret 12.

[0024] Among them, the lifting guide assembly 5 includes a lifting guide rail 51 arranged on one side of the assembly frame 1, and a lifting slider 52 corresponding to the lifting guide rail 51 is provided at one end of the turret lifting seat 11, and the lifting slider 52 is slidably arranged on the lifting guide rail 51.

[0025] Obviously, a fixed block 53 is provided at the upper end of the lifting guide rail 51 , and the fixed block 53 is movably inserted into the sliding channel in the lifting slider 52 through a guide shaft 54 ​​.

[0026] When the turret lift base 11 is raised or lowered, the lifting slider 52 is guided by sliding on the lifting guide rail 51, and the guide shaft 54 ​​ensures the stability of the turret lift base 11 during the lifting process, reducing the accuracy loss caused by shaking and vibration.

[0027] It can be seen that L-shaped lifting guide grooves 55 are provided on both sides of one end of the turret lifting seat 11 away from the lifting slide 52 , and the inner wall of the lifting guide groove 55 is in contact with the outer wall of one side of the assembly frame 1 .

[0028] The lifting guide groove 55 cooperates with the chamfered shape of one end of the assembly frame 1 to ensure the stable lifting of the other end of the turret lifting seat 11 and reduce shaking.

[0029] Furthermore, the lifting control assembly 2 includes a lifting shaft 21 that passes through the turret lifting seat 11, the upper end of the lifting shaft 21 is positioned at the upper end of the assembly frame 1 through a positioning sleeve 22, and the lower end of the lifting shaft 21 is connected to the positioning connection hole 23 at the bottom of the assembly frame 1.

[0030] Furthermore, the linkage drive structure 3 includes a linkage sleeve 31 arranged at one end of the lifting shaft 21 located on the upper end surface of the assembly frame 1, and a linkage pulley 32 is provided on the circumferential outer side of the linkage sleeve 31, which can drive the lifting shaft 21 to rotate synchronously. A lifting drive motor 33 is provided on one side of the assembly frame 1, and a driving pulley 34 is provided at the output shaft end of the lifting drive motor 33. The driving pulley 34 is connected to the linkage pulley 32 through a linkage belt body 35.

[0031] The turret lifting seat 11 is provided with a threaded hole that cooperates with the lifting shaft 21. When the lifting drive motor 33 is started, the lifting shaft 21 rotates, and the turret lifting seat 11 is forced to move up and down to adjust the height position.

[0032] Specifically, a positioning plate frame 36 is provided on the upper end surface of the assembly frame 1, and a positioning through hole 37 is provided at one end of the positioning plate frame 36 for one end of the output shaft of the lifting drive motor 33 to pass through, and a positioning bearing sleeve 38 is provided in the positioning through hole 37 and is sleeved on the output shaft. A limiting partition 39 is connected to the turret lifting seat 11 and is located between the turret drive motor 13 and the lifting drive motor 33.

[0033] The positioning plate frame 36 and the positioning bearing sleeve 38 function to maintain the rotation stability of the output shaft of the lifting drive motor 33 .

[0034] More specifically, the lifting and deceleration assembly 4 includes a deceleration shaft 41 that passes through the turret lifting seat 11. The upper end of the deceleration shaft 41 is rotatably positioned on the assembly frame 1 and the lower end is rotatably positioned in the rotation positioning hole 42 at the bottom of the assembly frame 1. A deceleration motor 43 is connected to the turret lifting seat 11, and the output end of the deceleration motor 43 and the deceleration shaft 41 are connected and braked via a bevel gear.

[0035] The turret lifting seat 11 is provided with a threaded hole for the reduction shaft 41 to pass through. When the lifting drive motor 33 starts running, the reduction motor 43 drives the bevel gear to maintain the same frequency operation to ensure the lifting power and lifting consistency. When the lifting drive motor 33 stops, the reduction motor 43 locks the bevel gear to brake the reduction shaft 41. Since the reduction shaft 41 is threadedly connected to the turret lifting seat 11, when the reduction shaft 41 stops, the turret lifting seat 11 quickly stops lifting.

[0036] In detail, a mounting back plate 14 is provided on one side of the turret lifting seat 11 , and the reduction motor 43 and the turret driving motor 13 are arranged on the mounting back plate 14 .

[0037] Preferably, the upper end surface of the assembly frame 1 is provided with a plurality of positioning locks 15 for positioning the assembly frame 1 outside.

[0038] The positioning lock 15 is used to fix the assembly frame 1 and ensure that the assembly frame 1 is in a stationary state when the turret lifting seat 11 is raised or lowered.

[0039] To sum up, the principle of this embodiment is that when the turret 12 needs to be raised and lowered to adjust the height, the lifting drive motor 33 is used to drive the lifting shaft 21 to rotate, driving the turret lifting seat 11 to move up and down. In the process of driving the turret lifting seat 11 to move, the lifting stability is maintained at both ends through the lifting guide assembly 5. When it is lifted to the set height, the lifting drive motor 33 stops, the reduction motor 43 starts the locking state, and the bevel gear is used to synchronously lock the reduction shaft 41, thereby realizing the locking and fixing of the lifting position of the turret lifting seat 11, and then fixing the height position of the turret 12.
