Description

Technical Field

[0001] The invention relates to the field of mechanical processing, and in particular to a self-feeding drilling and boring machine. Background Art

[0002] Track links and chain plates are important components of heavy machinery such as excavators and cranes. Track links are the basic units of crawler tracks, usually made of metal materials, connected together to form a continuous crawler track. They are responsible for distributing the weight of the machine to the ground and providing stable walking ability. In the processing of the links, surface drilling and boring are very important processes in the manufacturing process. Drilling and boring machines are usually used for processing. This machine tool can complete drilling and boring in the same process, avoiding secondary clamping of the links, saving time and cost.

[0003] For the drilling process of the chain link surface and the boring process of the hole, the existing drilling and boring machine is usually equipped with a drill bit and a boring tool on the main shaft, which can be switched according to the actual processing needs, that is, the first drilling process is performed, and then the boring process is performed. Due to the switching and processing characteristics of the two processes, the time consumption for a chain piece as a whole is relatively long, which affects the processing efficiency. There are also machines that perform boring and drilling processes on a chain piece at the same time, such as a CNC adjustable distance boring drill described in the existing patent CN216657064U All-in-one machine, in which the drilling spindle and boring tool are not set in the same direction. Drilling is usually a relatively fast process, the cutting speed of the drill is fast, and the feed speed is relatively high. Boring usually takes longer because it is mainly used to improve the accuracy and surface quality of the hole. The cutting speed of boring is usually lower than that of drilling, and the feed speed is also slower. To ensure the fineness of the processing, drilling is usually completed first, and then waiting for the boring process to be completed before the next chain link can be processed, which is also time-consuming and affects the processing efficiency.

[0004] Therefore, it is necessary to propose a self-propelled drilling and boring machine to solve the above problems. Summary of the invention

[0018] Compared with the prior art, the present invention provides a self-propelled drilling and boring machine, which has the following beneficial effects:

[0019] 1. The self-propelled drilling and boring machine can simultaneously perform surface drilling on the second chain link when boring a hole on one surface of the first chain link, and then perform boring on the second chain link while drilling another surface of the first chain link, so that the entire drilling and boring processes are performed continuously.

The friction between the fixing ring and the lifting block can ensure the stability of the lifting sleeve after the adjustment and movement during the rotation and adjustment of the rotating disk. After the lifting block is separated from the workbench, the reaction force generated by the compression of the third spring acts on the surface of the lifting block. The cylindrical protrusion mechanism on the surface of the lifting block and the fixing ring produce relative movement. The T-bar first produces relative movement with the lifting sleeve, and will not immediately drive the lifting sleeve to move in the direction away from the rotating disk. Therefore, during the rotation and adjustment of the rotating disk, the two clamping blocks can be in a stable state and the chain links can be stably clamped. After the drilling and boring processes of the chain links are completed, under the action of the elastic force of the third spring, the lifting sleeve will move in the direction away from the rotating disk, and the two clamping blocks will move in the direction away from each other, and automatic unloading can be performed, which can further improve the processing efficiency.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] The first adjusting mechanism 7 includes a limiting component 71 arranged on the surface of the annular groove 5 for limiting the upward and downward movement of the rotating disk 3 and an adjusting component 72 arranged on the lower surface of the rotating disk 3 for adjusting the rotation of the rotating disk 3 .

[0037] See also Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.12 The limiting assembly 71 includes a connecting block 711 symmetrically rotatably connected to the surface of the annular groove 5, a T-shaped column 712 is rotatably connected to the surface of the connecting block 711, a rotating sleeve 713 is slidably connected to the end of the surface of the T-shaped column 712 away from the connecting block 711, a first spring is fixedly connected to the inner wall of the rotating sleeve 713, and the end of the T-shaped column 712 away from the connecting block 711 is fixedly connected to the first spring, and the two rotating sleeves 713 are both rotatably connected to the workbench 11; the initial state of the first spring is a compressed state;

[0038] It should be noted that during the operation of the drilling mechanism 15, the drill bit will be adjusted to be close to the chain link according to the actual clamping state of the chain link, and drilling will be performed at the corresponding position on the surface of the chain link. During this process, the rotating sleeve 713 is adjusted to rotate, driving the rotating disk 3 to move toward the direction close to the workbench 11, and relative movement occurs between the T-shaped column 712 and the rotating sleeve 713. The first spring is compressed. By utilizing the elasticity and telescopicity of the first spring, the connecting block 711 is always coordinated with the annular groove 5 during the adjustment and movement of the rotating disk 3, thereby ensuring the stability of the rotating disk 3 during the adjustment and movement.

[0039] See also Figure 8 , Fig. 9 and Fig.10 The adjusting assembly 72 includes a first rotating ring 721 rotatably connected to the lower surface of the rotating disk 3, a second spring 722 is fixedly connected below the first rotating ring 721, an end of the second spring 722 away from the first rotating ring 721 is fixedly connected to the second rotating ring, the second rotating ring is rotatably connected to the workbench 11, a first vertical groove, a first spiral groove 723 and a second vertical groove 724 are provided on the surface of the rotating column 2, the first vertical groove and the second vertical groove 724 are both connected to the first spiral groove 723, a convex column is installed on the groove wall of the second vertical groove 724, and an end of the convex column away from the second vertical groove 724 is fixedly connected to the groove wall of the circular groove 12; the initial state of the second spring 722 is a compressed state;

[0040] The first spring 722 is in the state of being compressed, and the second spring 722 is used to make the rotating disk 3 remain in a stable state after being adjusted up and down. When the drilling mechanism 15 is running and drives one of the rotating sleeves 713 to rotate, the rotating disk 3 moves toward the direction close to the workbench 11, and the second spring 722 is compressed. The protruding column and the second vertical groove 724 produce relative movement, and then separate from the second vertical groove 724, and produce relative movement with the first spiral groove 723, which can drive the rotating column 2 to rotate. Since the rotating column 2 and the rotating disk 3 are rotatably connected by a one-way bearing, when the rotating disk 3 moves toward the direction close to the workbench 11, the rotating column 2 cannot drive the rotating disk 3 to rotate, and then separates from the first spiral groove 723 and cooperates with the first vertical groove. The rotating disk 3 moves away from the workbench 1 under the elastic force of the second spring 722. During the movement in the direction of 1, the protruding column moves relative to the first vertical groove, the first spiral groove 723 and the second vertical groove 724 in turn. At this time, the rotation of the rotating column 2 can drive the rotating disk 3 to rotate, and the rotation adjustment of the rotating disk 3 is completed. The clamped chain link can rotate with the rotation of the rotating disk 3, and the clamped chain link can move from the hole opening processing position to the boring processing position. The boring mechanism 16 further bores the hole opened on the surface of the chain link. During the process of adjusting the chain link from the drilling processing position to the boring processing position, the second adjusting mechanism 8 will also adjust the rotation angle. After the chain link is drilled, it can be quickly bored without removing the chain link and changing the angle to re-clamp it. The equipment does not need to be stopped, which shortens the time required for the drilling and boring processing of the chain link, improves the processing efficiency, and while drilling a chain link, another chain link that has been drilled is bored after drilling.

[0041] See also Figure 1 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 The clamping mechanism 6 includes a movable block 61 symmetrically slidably connected to the groove wall of the installation groove 4, one end of the two movable blocks 61 away from the installation groove 4 is rotatably connected to a horizontal column 62, one end of the horizontal column 62 is fixedly connected to a clamping block, and the other end of the horizontal column 62 is rotatably connected to a first gear 63 through a one-way bearing, the lower part of the first gear 63 is meshedly connected to a second gear 64, the lower part of the second gear 64 is meshedly connected to a third gear 65, and the lower part of the third gear 65 is meshedly connected to a fourth gear;

[0042] A rotating rod 67 is rotatably connected to the lower part of the movable block 61, and a movable sleeve 68 is slidably connected to the end of the rotating rod 67 away from the movable block 61. The two movable sleeves 68 are rotatably connected to each other, and the surfaces of the two movable sleeves 68 are cooperated with and installed with fixed columns. The upper ends of multiple fixed columns are fixedly connected to the rotating disk 3, and the lower surface of the rotating disk 3 is located next to the mounting groove 4 and is rotatably connected to a worm 69. The outer side of the worm 69 is meshedly connected to a worm wheel 610, and the upper part of the worm wheel 610 is meshedly connected to an L-shaped rack column 611. The lower end of the worm 69 is fixedly connected to a vertical column 612, and a second spiral groove 613 is provided on the outer side of the vertical column 612. A protrusion 614 is cooperated with and installed on the groove wall of the second spiral groove 613. A lifting sleeve 615 is sleeved on the outer side, the protrusion 614 is fixedly connected to the inner wall of the lifting sleeve 615, a fixing ring 616 is slidably connected to the upper end of the surface of the lifting sleeve 615, both fixing rings 616 are fixedly connected to the lower surface of the rotating disk 3, a third spring 617 is fixedly connected below the fixing ring 616, the third spring 617 is sleeved on the outer side of the lifting sleeve 615, one end of the third spring 617 away from the fixing ring 616 is fixedly connected to a lifting block 618, the lifting block 618 is installed in coordination with the fixing ring 616, a T-shaped rod 619 is fixedly connected to the surface of the lifting block 618 close to the lifting sleeve 615, and one end of the T-shaped rod 619 away from the lifting block 618 is slidably connected to the inner wall of the lifting sleeve 615;

[0043] A groove 620 is provided on the upper surface of the workbench 11 beside the circular groove 12, and an electric telescopic rod 621 is fixedly connected to the groove wall of the groove 620, and a T-shaped plate is fixedly connected to the other end of the electric telescopic rod 621; the surface edge of the T-shaped plate is chamfered;

[0044] It should be noted that, in the process of the rotating disk 3 being adjusted to move toward the direction close to the workbench 11, the lifting block 618 can contact with the surface of the workbench 11, and relative movement occurs between the lifting block 618 and the fixed ring 616, the third spring 617 is compressed, and relative movement occurs between the T-shaped rod 619 and the lifting sleeve 615. Then, the lifting block 618 can contact with the lower end of the lifting sleeve 615, driving the lifting sleeve 615 to move toward the direction close to the rotating disk 3, the protrusion 614 moves together with the lifting sleeve 615, and relative movement occurs between the protrusion 614 and the second spiral groove 613, driving the vertical column 612 to rotate, and the worm 69 rotates together with the vertical column 612, thereby driving the worm wheel 610 to rotate, the worm wheel 610 engages with the L-shaped rack column 611, the L-shaped rack column 611 is adjusted to move, and the L-shaped rack column 611 contacts with the surfaces of the two movable sleeves 68, driving the movable sleeve 68 to move in the direction away from the mounting groove 4. Due to the restriction of the fixed column The two movable sleeves 68 gradually decrease in angle, and the two rotating rods 67 rotate with the movable sleeves 68. The two movable blocks 61 approach each other to clamp and position the chain link, and then the multiple cylindrical protrusions extending upward on the surface of the lifting block 618 are in close contact with the surface of the fixing ring 616. The friction between the two can ensure the stability of the lifting sleeve 615 after adjustment. After the lifting block 618 is separated from the workbench 11, that is, during the rotation adjustment of the rotating disk 3, the reaction force generated by the compression of the third spring 617 acts on the surface of the lifting block 618, and the cylindrical protrusion mechanism on the surface of the lifting block 618 and the fixing ring 616 generate relative movement. The T-shaped rod 619 first generates relative movement with the lifting sleeve 615, and will not immediately drive the lifting sleeve 615 to move in the direction away from the rotating disk 3. Therefore, during the rotation adjustment of the rotating disk 3, the two clamping blocks can be in a stable state and the chain link can be stably clamped.

[0045] Since the worm wheel 610 and the worm 69 have a self-locking function, the two clamping blocks will not move after clamping the chain link, thus ensuring the stability of the clamping of the chain link;

[0046] It should be noted that the surface of the lifting sleeve 615 is provided with a plurality of recesses. During the relative movement between the lifting sleeve 615 and the fixing ring 616, the surface of the recesses can be in close contact with the surface of the fixing ring 616, thereby limiting the rotation of the lifting sleeve 615 and ensuring that the lifting sleeve 615 can stably drive the vertical column 612 to rotate when moving in the direction approaching the rotating disk 3.

[0047] See also Figure 1 , Figure 2 , Figure 3 and Fig.12The second adjustment mechanism 8 includes a first rack column 81 slidably connected to the upper surface of the rotating disk 3 and located next to the mounting groove 4. The first rack column 81 is meshed with the fourth gear. The end of the first rack column 81 away from the fourth gear is rotatably connected to a connecting rod 82. The two connecting rods 82 are installed through a torsion spring. The side of the movable block 61 is fixedly connected to a rectangular block 83. The end of the surface of the rectangular block 83 away from the movable block 61 is provided with a first oblique groove and a second oblique groove 84. The surface of the first rack column 81 is fixedly connected to a U-shaped column 85. The surface of the U-shaped column 85 is sleeved with a fourth spring. Spring, U-shaped column 85 is slidably plugged with movable block 61, one end of the fourth spring is fixedly connected to the U-shaped column 85, the other end of the fourth spring is fixedly connected to the movable block 61, the end of the U-shaped column 85 away from the movable block 61 is slidably connected with a lifting rod 86, the upper end of the lifting rod 86 is fixedly connected with a trapezoidal block 87, the lower end of the lifting rod 86 is fixedly connected with a friction block 88, the friction block 88 is installed in cooperation with the U-shaped column 85, the outer side of the lifting rod 86 is sleeved with a fifth spring, the upper end of the fifth spring is fixedly connected to the U-shaped column 85, and the lower end of the fifth spring is fixedly connected to the friction block 88;

[0048] It should be noted that, in the process of adjusting and rotating the rotating disk 3, the end of the first rack column 81 away from the fourth gear will contact the surface of the body 1, and the first rack column 81 is adjusted to move, driving the fourth gear to rotate, which is transmitted by the third gear 65, the second gear 64 and the first gear 63. Since the first gear 63 is rotatably connected to the cross column 62 via a one-way bearing, in the process of the first rack column 81 being adjusted to move in the direction of compressing the fifth spring, the rotation of the first gear 63 can drive the cross column 62 to rotate, but not vice versa, that is, when the first rack column 81 is restored to its initial position, the fifth spring can be set to facilitate the first rack column 81 to restore its initial position, so as to facilitate the next angle adjustment of the chain link. The setting of the torsion spring can facilitate the two clamping blocks to restore to their initial positions, so as to clamp and position chain links of different specifications. When the bar column 81 moves in the direction of compressing the fourth spring, the trapezoidal block 87 can produce relative movement with the first inclined groove and then separate. Under the elastic force of the fifth spring, the trapezoidal block 87 can be in close contact with the surface of the rectangular block 83, and the first rack column 81 is limited after adjustment. When the first rack column 81 is able to contact and move relatively with the chamfered portion of the T-shaped plate surface as the rotating disk 3 rotates, the first rack column 81 continues to move in the direction of compressing the fourth spring, and the trapezoidal block 87 contacts and moves relatively with the second inclined groove 84. Due to the friction between the friction block 88 and the U-shaped column 85, the trapezoidal block 87 will not quickly return to the initial position under the elastic force of the fifth spring. Under the elastic force of the fourth spring, the U-shaped column 85 can move in the direction away from the movable block 61, that is, the U-shaped column 85 can return to its initial position.

[0049] It should be noted that, after the rotating disk 3 is adjusted and rotated, the drilling mechanism 15 drills holes on the surface of the chain link, and the boring mechanism 16 bores the drilled holes. After all these are completed, since the chain link has been adjusted and rotated 90 degrees, if it is necessary to drill and bore the surface of the chain link after the rotation and adjustment, the electric telescopic rod 621 is extended to drive the T-shaped plate away from the rotating disk 3, so that the second adjustment mechanism 8 does not contact the surface of the T-shaped plate, the first rack column 81 does not return to the initial position, and the clamped chain link does not perform angle adjustment, so as to perform the surface of the chain link after the rotation and adjustment. Drilling processing, since the time required for boring processing is generally longer than the time consumed by drilling processing, if the drilling processing and boring processing of the holes on the same surface of the chain link are completed before the drilling processing and boring processing of the next surface of the chain link are carried out, the time consumed in processing the chain link will increase. After the drilling processing of the surface after the chain link is rotated and adjusted is completed, the rotating disk 3 is rotated and adjusted again to transport the chain link to the position for boring processing, and the boring processing is carried out again. The processing in this way can make the drilling processing process and the boring processing process of the chain link surface be carried out continuously, further improving the processing efficiency of the chain link;

[0050] The electric telescopic rod 621 can be controlled to extend or contract to control whether the first rack column 81 contacts the surface of the T-shaped plate, thereby controlling the angle of the clamped chain link to be adjusted. The clamped chain link can move back and forth between the boring processing area and the drilling processing area;

[0051] It should be noted that the drilling mechanism 15 and the boring mechanism 16 are components of the existing self-propelled drilling and boring machine, which are composed of a spindle, a drill bit, a boring tool, a motor, etc., and are existing mature technologies; the machine body 1 is an existing self-propelled drilling machine, which is usually composed of a bed, a spindle, a feeding system, a control system, etc., and is an existing mature technology and will not be repeated here. The drilling mechanism 15, the boring mechanism 16 and the electric telescopic rod 621 are all electrically connected to the control panel of the machine body 1.
