Description

Technical Field

[0001] This utility model relates to the field of spindle head lifting technology, specifically a spindle head lifting device for a pipe cutting machine. Background Technology

[0002] The spindle head lifting device of a pipe cutting machine is a core component that enables the vertical feeding and height adjustment of the cutting head. Its structural design and working principle directly affect cutting accuracy and efficiency. Common forms include lead screw and nut pairs, worm gear mechanisms, and threaded rod drives, converting rotary or linear motion into lifting motion. Through its precise structural design and efficient working principle, the spindle head lifting device has become an indispensable core component in modern manufacturing. Its technological advantages lie not only in high precision and stability but also in its flexible customization and intelligent upgrade potential.

[0003] In existing technologies, such as the die head lifting system disclosed in CN214521786U, a die is installed under the die head, which is connected to a main shaft. The main shaft is connected to an extrusion motor that drives the die to rotate, thereby producing filter screen products. The die head lifting system includes a drive motor connected to the main shaft for driving the main shaft to lift and lower, and a feedback device for detecting the rotational torque of the extrusion motor and feeding it back to the drive motor. The drive motor is connected to the main shaft through a cooperating worm gear and worm wheel. A thrust bearing is installed on the main shaft. By using a drive motor with feedback control, it can achieve timely and efficient automatic lifting and lowering of the main shaft and die head, reducing the workload of personnel and improving production efficiency.

[0004] Existing lifting devices, by using a drive motor with feedback control, can achieve timely and efficient automatic lifting of the spindle and machine head, reducing the workload of personnel and improving production efficiency. However, during use, because the spindle and machine head lifting device only uses one mechanism for lifting, the supporting force on the machine head is unevenly distributed, resulting in poor stability when cutting steel pipes. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem that the spindle head lifting device only uses one mechanism for lifting, resulting in uneven distribution of support force on the head and poor stability when cutting steel pipes.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A spindle head lifting device for a pipe cutting machine includes a device frame, the upper surface of which is provided with a lifting mechanism for lifting the spindle head, and a fixing mechanism for fixing the spindle head is provided above the lifting mechanism.

[0009] The lifting mechanism includes a first lifting component, which is fixed to the upper surface of the device frame by bolts. A second lifting component is fixed to the upper end of the device frame. A third lifting component is connected to one side of the second lifting component. A fourth lifting component is connected to the side wall of the third lifting component. A commutator is fixed above the device frame.

[0010] As a further improvement of this utility model: a drive handle is connected to the right side of the commutator, and a transmission rod is connected to the output shaft of the commutator.

[0011] As a further embodiment of this utility model: the end of the transmission rod is fixed with a first helical tooth, and a second helical tooth meshes with one side of the first helical tooth.

[0012] As a further embodiment of this utility model: a lead screw is fixed inside the second helical tooth, a fixed bearing embedded in the inner wall of the second lifting component is sleeved at the lower end of the second helical tooth, and a threaded tube is threaded to the upper end of the lead screw.

[0013] As a further embodiment of this utility model: the fixing mechanism includes a mounting plate, which is welded to the upper surface of the threaded pipe.

[0014] As a further improvement of this utility model: two guide tubes are welded to the lower end of the mounting plate, and the lower ends of the two guide tubes are telescopically connected to guide rods that are fixedly connected to the device frame.

[0015] As a further improvement of this utility model: two mounting brackets are fixed on one side of the mounting plate, and the main shaft body is placed inside the mounting bracket.

[0016] As a further improvement of this utility model, both of the mounting brackets are equipped with fixing bolts that are threadedly connected to the main shaft body.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model drives the threaded pipe connected by the second helical tooth to move vertically, and the mounting plate is driven to move vertically, which lifts and lowers the main shaft body on the mounting plate. The main shaft body is lifted and lowered synchronously by four lifting mechanisms, which can effectively avoid uneven distribution of support force on the main shaft body, thereby improving the stability when cutting steel pipes.

[0019] 2. This utility model uses a guide tube on the mounting plate, which, in conjunction with a guide rod, can play a guiding role, thereby improving the stability of the mounting plate during lifting and lowering. By unscrewing the fixing bolts through the mounting bracket on the mounting plate, the spindle body can be disassembled, which facilitates the maintenance of the spindle body and makes it easy to assemble and use with different spindle bodies.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Please see Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a spindle head lifting device for a pipe cutting machine, including a device frame 1. The upper surface of the device frame 1 is provided with a lifting mechanism for lifting the spindle head, and a fixing mechanism for fixing the spindle head is provided above the lifting mechanism.

[0031] The lifting mechanism includes a first lifting component 2, which is fixed to the upper surface of the device frame 1 by bolts. A second lifting component 21 is fixed to the upper end of the device frame 1. A third lifting component 22 is connected to one side of the second lifting component 21. A fourth lifting component 23 is connected to the side wall of the third lifting component 22. A commutator 24 is fixed above the device frame 1.

[0032] Specifically, a drive handle 25 is connected to the right side of the commutator 24, and a transmission rod 26 is connected to the output shaft of the commutator 24.

[0033] Furthermore, by manually rotating the drive handle 25, the commutator 24 is driven to operate, thereby raising and lowering the spindle head.

[0034] Specifically, a first helical tooth 27 is fixed at the end of the transmission rod 26, and a second helical tooth 28 is engaged on one side of the first helical tooth 27.

[0035] Furthermore, the commutator 24 drives the first helical tooth 27 to rotate via the transmission rod 26, causing the first helical tooth 27 to mesh with the second helical tooth 28 and rotate.

[0036] Specifically, a lead screw 3 is fixed inside the second helical tooth 28, and a fixed bearing 29 embedded in the inner wall of the second lifting component 21 is sleeved at the lower end of the second helical tooth 28. A threaded tube 4 is threadedly connected to the upper end of the lead screw 3.

[0037] Furthermore, when the second helical tooth 28 rotates, it can drive the lead screw 3 to rotate, and the mounting plate 5 is driven to move vertically, thereby raising and lowering the main shaft on the mounting plate 5.

[0038] In use, the device frame 1 is placed in a suitable position. When raising or lowering the spindle head, the operator can manually turn the drive handle 25, which in turn drives the commutator 24. The commutator 24 drives the first helical gear 27 to rotate via the transmission rod 26, causing the first helical gear 27 to mesh with the second helical gear 28. The second helical gear 28 is equipped with a transmission mechanism connected to another lifting component, so that when one of the second lifting components 21 is running, it will synchronously drive the first lifting component 2, the third lifting component 22, and the fourth lifting component 23 to run. When the second helical gear 28 rotates, it can drive the lead screw 3 to rotate. The fixed bearing 29 ensures the smooth rotation of the second helical gear 28, allowing the second helical gear 28 to drive the threaded pipe 4 connected by the thread to move vertically. At this time, the mounting plate 5 is driven to move vertically, thereby raising and lowering the spindle body 54 on the mounting plate 5. The spindle body 54 is raised and lowered synchronously by four lifting mechanisms, which can effectively avoid uneven distribution of support force on the spindle body 54, improve the stability of the spindle body 54 when cutting steel pipes, and engineers can remove the drive handle 25 on the commutator 24 and use the motor to drive the commutator 24, thus eliminating the need for manual driving and saving manpower.

[0039] In summary, when the spindle head lifting device of the pipe cutting machine is in use, the rotation of the second helical tooth 28 drives the threaded pipe 4 connected by the thread to move vertically, and the mounting plate 5 is driven to move vertically, so as to lift the spindle body 54 on the mounting plate 5. The spindle body 54 is lifted and lowered synchronously by four lifting mechanisms, which can effectively avoid uneven distribution of support force on the spindle body 54.

[0040] Example 2

[0041] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0042] Specifically, the fixing mechanism includes a mounting plate 5, which is welded to the upper surface of the threaded tube 4. Two guide tubes 51 are welded to the lower end of the mounting plate 5, and the lower ends of the two guide tubes 51 are telescopically connected to guide rods 52 that are fixedly connected to the device frame 1.

[0043] Furthermore, the guide tube 51 provided on the mounting plate 5, in conjunction with the guide rod 52, can play a guiding role.

[0044] Specifically, two mounting brackets 53 are fixed on one side of the mounting plate 5, and the spindle body 54 is placed inside the mounting bracket 53.

[0045] Furthermore, the mounting bracket 53 provided on the mounting plate 5 facilitates the fixation of the spindle body 54.

[0046] Specifically, both mounting brackets 53 have fixing bolts 55 that are threadedly connected to the spindle body 54 installed inside.

[0047] Furthermore, by unscrewing the fixing bolts 55, the spindle body 54 can be disassembled, thereby facilitating the maintenance of the spindle body 54.

[0048] In use, the guide tube 51 on the mounting plate 5, in cooperation with the guide rod 52, can play a guiding role, thereby improving the stability of the mounting plate 5 when it is raised and lowered. After unscrewing the fixing bolts 55 through the mounting bracket 53 on the mounting plate 5, the spindle body 54 can be disassembled, which facilitates the maintenance of the spindle body 54 and makes it convenient to assemble and use different spindle bodies 54.

[0049] In summary, when the spindle head lifting device of this pipe cutting machine is in use, the rotation of the second helical tooth 28 drives the threaded pipe 4 connected by the thread to move vertically, and the mounting plate 5 is driven to move vertically, so as to lift the spindle body 54 on the mounting plate 5. The spindle body 54 is lifted and lowered synchronously by four lifting mechanisms, which can effectively avoid uneven distribution of support force on the spindle body 54. Furthermore, the spindle body 54 can be disassembled by unscrewing the fixing bolts 55 through the mounting bracket 53 on the mounting plate 5, which facilitates the maintenance of the spindle body 54 and the assembly and use of different spindle bodies 54.
