Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, and in particular to a lathe for producing and processing a breaker hammer. Background Art

[0002] A breaker hammer is usually mounted on an excavator and used in construction and demolition projects, especially in the crushing of concrete structures. It consists of a cylinder assembly and a drill rod. When working, the drill rod strikes the target material downward to quickly release energy, and the drill rod violently collides with the object to break it into small pieces. Breakers are widely used in bridge demolition, road crushing and other scenarios due to their high efficiency, strong mobility and ability to work in confined spaces.

[0003] The drill rod is an important part of the breaker hammer. During the production and processing of the breaker hammer, a lathe is needed to turn the drill rod workpiece to meet the qualified size requirements. During the lathe processing, a lot of metal burrs and debris will be generated. These burrs and debris adhere to the surface of the drill rod workpiece, and the surface quality of the drill rod will be damaged during the reprocessing process. At the same time, the relative sliding between the tool and the drill rod will aggravate the wear of the tool. Traditional machine tools only use cutting fluid to flush these burrs and debris. Since the burrs are integrated with the drill rod workpiece, and smaller debris will adhere to the drill rod workpiece, the cleaning effect is poor. At the same time, the tool setting process of traditional lathes is relatively cumbersome and needs to be improved urgently. Summary of the invention

DETAILED DESCRIPTION

[0025] like Figure 1 As shown, Figure 1 This is a schematic structural diagram of an implementation mode of a lathe for producing and processing a breaker hammer proposed by the present invention.

[0026] Reference Figure 1 A lathe for producing and processing a breaker hammer proposed in the present invention comprises a bed 1, a chuck assembly 2, a tailstock assembly 3, a tool holder assembly 4, a drive assembly 5, and a turning fluid spraying assembly. The bed 1 is provided with a first guide rail 11, the chuck assembly 2 is fixedly mounted at one end of the first guide rail 11, the tailstock assembly 3 is movably mounted at the other end of the first guide rail 11, a placement space 12 for placing a workpiece is provided between the chuck assembly 2 and the tailstock assembly 3, the turning fluid spraying assembly is installed on the bed 1, and an output end thereof is located in the placement space 12, the tool holder assembly 4 is slidably mounted on the bed 1, the tool holder assembly 4 is provided with a second guide rail arranged along the width direction of the bed 1 and a tool mounting portion 41 for fixing a turning tool, the tool mounting portion 41 is mounted on the second guide rail so that it can move along the second guide rail and enter the placement space 12, the drive assembly 5 is mounted on the bed 1, and an output end thereof is mounted on the tool holder assembly 4 for driving the tool holder assembly 4 to reciprocate along the length direction of the bed 1.

[0027] It should be noted that the bed 1, chuck assembly 2, tailstock assembly 3, tool holder assembly 4, drive assembly 5, and turning fluid spraying assembly are all relatively mature technologies on lathes and are all existing technologies, which will not be elaborated here. The drive assembly 5 is a power assembly installed in the tool feeding box to drive the first type of screw to rotate, and the first type of screw acts on the tool holder assembly 4.

[0028] Reference Figure 2 In a further embodiment, the tool holder assembly 4 also has a cleaning portion 42, which includes a mounting seat 421, a telescopic rod 422, a brush head 423, a slider 424, and a screw rod 425. The mounting seat 421 is fixed to a side of the tool holder assembly 4 close to the placement space 12, and the mounting seat 421 is located below the tool mounting portion 41. The mounting seat 421 has a third guide rail 4211 arranged along the width direction of the bed 1. The telescopic rod 422 is mounted on the third guide rail 4211 through the slider 424. The brush head 423 is detachably mounted on the top of the telescopic rod 422. One end of the screw rod 425 is rotatably mounted on the mounting seat 421. The free end of the screw rod 425 is assembled in a screw hole opened on the slider 424 and extends out. The screw rod 425 is arranged parallel to the third guide rail 4211. The rotation of the screw rod 425 can drive the telescopic rod 422 to drive the brush head 423 into the placement space 12.

[0029] During the specific implementation of this embodiment, when the drill rod processing part is installed in the three-jaw chuck in the chuck assembly 2, the screw rod 425 is rotated to drive the slider 424 to slide along the third guide rail 4211 to adjust the contact point between the brush head 423 and the drill rod processing part so that the two are in full contact, and the burrs and debris on the drill rod are cleaned by the bristles on the brush head 423.

[0030] During the use of the lathe, in order to control the amount of tool feed, the tip of the tool needs to be aligned with the rotation center of the workpiece to ensure the processing accuracy of the workpiece. The lathe tool rest assembly 4 has a tool rest for installing the tool. During the installation of the tool, the longitudinal height of the tool needs to be adjusted. Generally, a gasket needs to be placed under the tool for adjustment. In the traditional lathe, there is a lack of reference for the tool adjustment amount, and repeated adjustments are required. To solve this problem, the following solution is proposed:

[0031] Reference Figure 2The cleaning part 42 also has a rotating shaft 427 and two abutment members 426. The telescopic rod 422 includes a first tube body 4221, a second tube body 4222, and a spring. The first tube body 4221 is sleeved on the second tube body 4222. The spring is installed between the bottom end surface of the second tube body 4222 and the bottom surface of the first tube body 4221. The two abutment members 426 are rotatably installed on the free end of the second tube body 4222 through the rotating shaft 427. Each abutment member 426 has a first abutment surface 4261 parallel to the upper end surface of the bed 1. The first abutment surface 4261 is located on the top surface of the abutment member 426. The rotating shaft 427 Arranged along the length direction of the bed 1, the two abutment members 426 both have a horizontal ruler arranged along the width direction of the bed 1, the tool mounting portion 41 has a tool mounting station 411, the mounting seat 421 has a reference line 4212 arranged along the length direction of the bed 1, the third guide rail 4211 has a starting position, the distance between the starting position and the reference line 4212 is equal to the distance between the reference line 4212 and the bottom end surface of the tool mounting station 411, and the angle between the axis of the three-jaw chuck in the chuck assembly 2 and the plane where the reference line 4212 is located and the vertical direction and the horizontal direction are equal.

[0032] It should be noted that the drill rod production stock and the drill rod finished product are both cylindrical, and the size difference between the two is not much, so the tool has a limited cutting amount during the process of processing the production stock. Although the two abutment members 426 move with the tool, they can also contact the production stock under the limitation of the cutting amount and the telescopic rod 422;

[0033] The two abutment members 426 have the following functions: first, to assist in tool setting of the lathe by utilizing the contact state between the first abutment surface 4261 and the blank produced by the drill rod; second, to scrape off the burrs generated during the blank turning process and then clean them with the brush head 423 .

[0034] When this scheme is implemented, the slider 424 is moved to the starting position of the third guide rail 4211. When the drill rod processing part is successfully installed, the screw rod 425 is rotated to drive the slider 424 to slide along the third guide rail 4211 to adjust the contact point between the brush head 423 and the drill rod processing part; during the adjustment process, since the abutment 426 contacts the drill rod processing part through the first abutment surface 4261, the two are pressed together under the action of the spring force. Since the drill rod processing part is cylindrical, a circle and a surface contact is formed. In the initial state, the direction of the spring force is not in the same direction as the pressure of the drill rod processing part on the first abutment surface 4261, and the level ruler is not in a horizontal state; during the adjustment process, due to the change in the position of the first abutment surface 4261 and the drill rod processing part, the level ruler gradually It is gradually in a horizontal state. When the first abutment surface 4261 is located directly below the drill rod processing part, the direction of the spring force and the pressure exerted on the first abutment surface 4261 by the drill rod processing part are both in a vertical state. The spirit level is in a horizontal state, and the moving dimension of the slider 424 can be read. Since the distance dimension between the starting station and the reference line 4212 is equal to the distance dimension between the reference line 4212 and the bottom end surface of the tool installation station 411, the longitudinal adjustment amount of the tool is also equal to the moving dimension of the slider 424. Therefore, the longitudinal adjustment amount of the tool is converted into the moving dimension of the slider 424. Therefore, the moving dimension of the slider 424 can be read to adjust the longitudinal adjustment dimension of the tool, thereby improving the docking efficiency of the lathe. In this state, the tip of the tool is located on the bottom end surface of the tool installation station 411.

[0035] When the drill rod workpiece is installed and the level ruler is in a horizontal state, there is no need to align the tool.

[0036] During the implementation of the above solution, since the first abutting surface 4261 is always in contact with the drill rod workpiece during the turning process to scrape the burrs on the surface of the drill rod workpiece, it will also wear itself, so that the direction of the pressure on the first abutting surface 4261 from the drill rod workpiece changes due to its own wear. Therefore, the level ruler cannot accurately measure the horizontal state of the first abutting surface 4261, causing the moving size of the slider 424 to lose its reference value. In order to solve this problem, the following further solution is proposed:

[0037] Reference Figure 3 and Figure 4In a further embodiment, the lathe further comprises an adjusting assembly 6, which is mounted in the second tube body 4222. The adjusting assembly 6 comprises a first gear 61, a second gear 62, a third gear 63, a rack 64, a slide rail 65, and an adjusting rod 66. The first gear 61 is mounted on the rotating shaft 427, the second gear 62 and the third gear 63 are coaxially mounted in the second tube body 4222, the first gear 61 is transmission-connected with the second gear 62, and the rack 64 is slidably mounted on the side wall of the second tube body 4222 through the slide rail 65. The rack 64 is meshed with the third gear 63, the adjusting rod 66 is installed on the rack 64, and its free end extends from the guide groove provided on the second tube body 4222, the first gear 61 is the same as the second gear 62, the guide groove is arranged along the length direction of the second tube body 4222, and the bottom end surfaces of the two abutting members 426 are provided with a second abutting surface 4262 arranged parallel to the first abutting surface 4261, driving the adjusting rod 66 to slide along the guide groove, which can drive the first abutting surface 4261 and the second abutting surface 4262 to exchange positions.

[0038] When this scheme is implemented, the adjusting rod 66 drives the rack 64 to slide along the slide rail 65. This process drives the third gear 63 to rotate, and the third gear 63 drives the first gear 61 to rotate through the second gear 62. Since the first gear 61 is installed on the rotating shaft 427, it drives the abutment 426 to rotate, so that the first abutment surface 4261 and the second abutment surface 4262 are swapped. Since the second abutment surface 4262 is not worn, the first abutment surface 4261 and the drill rod workpiece are switched when the overall position is switched, which can ensure the reference value of the moving size of the slider 424 and improve the tool setting efficiency of the lathe.

[0039] In the above scheme, since the rotating shaft 427 is equipped with the first gear 61, the gears have a locking function. During the adjustment process, the rotation of the abutment member 426 depends on the rotation of the first gear 61 rather than the extrusion of the first abutment surface 4265 and the drill rod workpiece. To solve this problem, the following preferred scheme is proposed:

[0040] Reference Figure 2-Figure 4Preferably, the abutment member 426 has a special-shaped mounting groove 4263, and the end of the rotating shaft 427 has a special-shaped assembly block 4271. The special-shaped mounting groove 4263 has a first arc portion and a first matching portion 4264, and the two ends of the first arc portion and the two ends of the first matching portion 4264 are smoothly connected. The first matching portion 4264 has two oppositely arranged first abutting surfaces 4265, and the intersection of the two first abutting surfaces 4265 is close to the first abutting surface 4261. The special-shaped assembly block 4271 has a second arc portion and a second matching portion 4272, and the two ends of the second arc portion and the two ends of the second matching portion 4272 are smoothly connected. The second matching portion 4272 has two oppositely arranged second abutting surfaces 4273, and the size of the special-shaped mounting groove 4263 is larger than the size of the special-shaped assembly block 4271. The two second abutting surfaces 4273 respectively abut on the two first abutting surfaces 4265 to form a locking between the abutment member 426 and the rotating shaft 427.

[0041] It should be noted that the abutment member 426 can be composed of multiple parts, which are assembled on the rotating shaft 427 during installation. There are various installation methods, which will not be described in detail.

[0042] In this scheme, a special-shaped installation groove 4263 and a special-shaped assembly block 4271 are used to complete the assembly of the abutment 426 and the rotating shaft 427. When the first abutment surface 4261 contacts the drill rod processing part, the two second abutment surfaces 4273 respectively abut against the two first abutment surfaces 4265. At this time, the abutment 426 and the rotating shaft 427 cannot move relative to each other, which can improve the contact stability between the abutment 426 and the drill rod processing part during turning; when the second abutment surface 4262 contacts the drill rod processing part, the two second abutment surfaces 4273 are separated from the two first abutment surfaces 4265, and the second circular arc portion abuts against the first circular arc portion. At this time, the abutment 426 and the rotating shaft 427 can rotate. When the rotating shaft 427 is locked, the rotation of the abutment 426 relies on the extrusion of the second abutment surface 4262 and the drill rod processing part.

[0043] Reference Figure 6 , wherein each abutment member 426 also has an arc-shaped portion 4266 and two oppositely arranged guide surfaces 4267, the arc-shaped portion 4266 is arranged between the first abutment surface 4261 and the second abutment surface 4262, and the two ends of the arc-shaped portion 4266 are smoothly connected to the end of the first abutment surface 4261 and the end of the second abutment surface 4262 respectively, when the surface of the workpiece is uneven, the passability of the abutment member 426 can be increased.

[0044] The two guide surfaces 4267 are respectively arranged on the two side surfaces of the abutment 426 along the axial direction of the rotating shaft 427, and one end of the two guide surfaces 4267 is smoothly connected to the two sides of the first abutment surface 4261, which can increase the smoothness of its rotation when the abutment 426 rotates.

[0045] Reference Figure 5 In another embodiment, the device further includes a fine-tuning assembly 7, the tool mounting portion 41 has a pressing plate 412, a bearing plate 413, and a connecting block 414, the bearing plate 413 is fixedly connected to the pressing plate 412 through the connecting block 414, the size of the connecting block 414 is smaller than the pressing plate 412 and the bearing plate 413 so that a tool mounting station 411 is formed between the pressing plate 412 and the bearing plate 413, the bearing plate 413 has an installation space 4131 inside, the fine-tuning assembly 7 is installed in the installation space 4131, and the fine-tuning assembly 7 includes a first slider 71, a second slider 72, a first screw 73, the second slider 72 is slidably installed in the installation space 4131, the first slider 71 is slidably installed in the through groove opened on the top of the supporting plate 413 and extends into the installation space 4131 to abut against the top surface of the second slider 72, the top surface of the second slider 72 is arranged inclined, the first screw rod 73 is rotatably installed on the second slider 72 and extends out of the screw hole opened on the supporting plate 413, the moving directions of the first slider 71 and the second slider 72 are perpendicular, and the first screw rod 73 is rotated to drive the second slider 72 to move to force the first slider 71 to rise and enter the tool installation station 411.

[0046] When the height of the tool needs to be adjusted, the first screw 73 is rotated, and the first screw 73 drives the second slider 72 to move in the installation space 4131. Since the top surface of the second slider 72 is inclined, the first slider 71 rises or falls, thereby adjusting the height of the tool.

[0047] Reference Figure 7 In another embodiment, the lathe also includes an auxiliary loading mechanism 8, and the bed 1 has a accommodating space for accommodating the auxiliary loading mechanism 8, and the accommodating space is located at the bottom of the placement space 12. The auxiliary loading mechanism 8 includes an auxiliary mounting component 81 and a horizontal lifting slide 82 for lifting the auxiliary mounting component 81. The auxiliary mounting component 81 includes a first plate body 811 and a second plate body 812. The first plate body 811 is rotatably mounted on the top surface of the horizontal lifting slide 82, and the second plate body 812 is slidably mounted on the first plate body 811 through a fourth guide rail 813.
