Description

Technical Field

[0001] The present invention belongs to the technical field of boring machining, and specifically relates to a boring device for machining an automobile engine cylinder head. Background Art

[0002] For the cylinder head of an automobile engine, the cylinder head is installed on top of the cylinder block, sealing the cylinder from above and forming a combustion chamber. The overall structure of the cylinder head is generally rectangular, with a complex detailed structure and various holes, such as mounting holes and valve holes. The hole positions need to be bored through a boring device to ensure the quality of the cylinder head.

[0003] A boring device and method for machining an automobile engine cylinder head with the application number CN202510037653.5 can machine holes with an inclined angle on the automobile engine cylinder head by adjusting the inclination angle of the boring component. However, the machining coverage area of the boring tool of this lathe is small. If oblique cutting is performed on the side part of the cylinder head, the coverage area of the component above for controlling the movement of the boring tool is much larger than the area of the lower placement seat, resulting in low space utilization rate of the device. Moreover, the movement path of the boring tool is long, which makes the movement accuracy of the boring tool lower. The longer movement time will also lead to a decrease in cutting efficiency, and the technical requirements for the component controlling the movement of the boring tool will be higher. Therefore, improvements are needed. Summary of the Invention

[0004] Aiming at the problem of insufficient flexibility caused by limited sliding distance of the boring tool in the prior art, the technical solution adopted by the present invention is: a boring device for machining an automobile engine cylinder head, including:

[0005] A boring component, arranged on the ceiling, for performing boring and drilling operations on the cylinder head below;

[0006] An integrated bottom box, arranged on the ground;

[0007] A frame shell component, arranged inside the integrated bottom box, for placing the cylinder head;

[0008] The frame shell component includes:

[0009] A thick connecting plate, at the center of the bottom of the inner cavity of the thick connecting plate, a thick connecting rod is fixedly installed, and both ends of the thick connecting rod extend to the outside of the thick connecting plate. The bottom of the thick connecting plate is an arc surface structure;

[0010] Control components, symmetrically arranged on the left and right sides of the thick connecting rod, controlling the position of the thick connecting plate through the thick connecting rod;

[0011] A top frame plate, arranged on the top of the thick connecting plate, with the cylinder head arranged on the upper surface of the top frame plate;

[0012] Among them, the control component includes:

[0013] A side guide rail, the outer surface of which is fixedly connected to the inner wall of the container bottom box, and the bottom of the inner wall of the side guide rail is slidably connected to an embedded slider through a slide groove;

[0014] A deflection motor, wherein the outer surface of the deflection motor is fixedly connected to the top of the embedded slider, and the outer surface of the output shaft of the deflection motor is plugged into the axis of the thick connecting rod;

[0015] A sleeve rotating wheel, the inner wall of which is rotatably connected to the outer surface of the thick connecting rod;

[0016] Transmission belt, electric wheels are symmetrically arranged on both sides of the inner wall of the transmission belt, the outer surface of the sleeve wheel is rollingly connected to the inner wall of the transmission belt, and the outer surface of the transmission belt is slidingly connected to the inner cavity of the side guide rail. When the transmission belt rotates, it can drive the sleeve wheel to roll along the side guide rail in a directional manner. At this time, the inner wall of the sleeve wheel and the outer surface of the coarse connecting rod rotate relative to each other, so the sleeve wheel can drive the coarse connecting plate to slide along the inner wall of the side guide rail in a directional manner when rolling.

[0017] Furthermore, the frame housing component also includes:

[0018] A push rod, the push rod is arranged in the inner cavity of the top frame plate, the top end of the push rod is plugged into the inner wall of the cylinder cover through the limit rod, the push rod can push the top rod body upward, and then insert it into the interface of the inner wall of the cylinder cover. If there is no interface at the corresponding position of the inner wall of the cylinder cover, the rod body of the push rod is retracted to the inside of the top frame plate, so that the area on the upper surface of the top frame plate is relatively smooth;

[0019] A side clamping plate, the bottom of which is slidably connected to the inner cavity of the top frame plate through a notch, and the outer surface of the side clamping plate and the outer surface of the cylinder head are pressed against each other;

[0020] A limit motor, the outer surface of which is fixedly connected to the side of the top frame through an extension frame, a threaded push rod is provided on the outer surface of the output shaft of the limit motor, and one end of the threaded push rod away from the limit motor is rotatably connected to the lower part of the outer surface of the side clamp, and the outer surface of the threaded push rod is threadedly connected to the inner cavity of the top frame through a threaded groove.

[0021] Further, including,

[0022] A stabilizing component, the stabilizing component comprising:

[0023] A smooth pressurized box, the bottom of which is slidably connected to the bottom of the inner wall of the container bottom box;

[0024] A hollow through pipe, the bottom end of which is plugged into an interface on the upper surface of the smooth pressurized box;

[0025] The attached arc plate, the inner wall of the attached arc plate is rotatably connected to the bottom of the outer surface of the thick connecting plate. The inner cavity of the attached arc plate is evenly provided with docking notches. The lower surface of the attached arc plate is fixedly connected to the top end of the hollow through pipe through the docking notches. The inner wall of the attached arc plate is always sleeved with the arc surface at the bottom of the thick connecting plate. When the thick connecting plate rotates, the bottom of the thick connecting plate will also have relative sliding with the inner wall of the attached arc plate. When the smooth pressure box sucks air through the hollow through pipe to the inner wall of the attached arc plate, the thick connecting plate will be tightly attached to the inner wall of the attached arc plate under the adsorption effect, and thus it is difficult to perform sliding movement on the inner wall of the attached arc plate.

[0026] Further, the boring component includes

[0027] A horizontal sliding component, the upper surface of the horizontal sliding component is arranged on the ceiling;

[0028] A control box, a torque end is slidably connected to the bottom of the inner cavity of the control box, and a cutting tool head is arranged at the axis of the bottom end of the torque end;

[0029] A fine-tuning component, the fine-tuning component is arranged on the outer surface of the cutting tool head and is used to control the cutting tool head to perform a small-amplitude movement;

[0030] A heat-resistant component, which is arranged below the fine-tuning component and is used to cool the cutting tool head.

[0031] Further, the horizontal sliding component includes

[0032] A limiting flat plate, a guiding frame is arranged on the lower surface of the limiting flat plate;

[0033] A pressure control cylinder, the outer surface of the pressure control cylinder is slidably connected to the inner cavity of the limiting flat plate through a plug board, and a segmented push rod is inserted on the outer surface of the air outlet of the pressure control cylinder. The end of the segmented push rod away from the pressure control cylinder is fixedly connected to a connecting clamping plate, and the outer surface of the connecting clamping plate is fixedly connected to the top of the control box. The pressure control cylinder makes the segmented push rod extend or contract by means of pressurization and decompression, so as to achieve the effect of moving the control box in the plane position.

[0034] Further, the cutting tool head includes

[0035] A plug-in end, the inner cavity of the plug-in end is plugged with the bottom end of the torque end;

[0036] A boring tool rod, the top end of the boring tool rod is fixedly connected to the axis of the inner cavity of the plug-in end, and a circumferential cutting groove is arranged on the upper part of the outer surface of the boring tool rod.

[0037] Further, the fine-tuning component includes

[0038] Scale sliding housing, on the side part of the scale sliding housing, there is a scale groove with higher precision. The inner wall of the scale sliding housing is slidably connected with a connecting rotating sleeve. The inner wall of the connecting rotating sleeve is sleeved with the outer surface of the boring cutter bar through a circumferential cutting groove. There are balls arranged on the inner wall of the connecting rotating sleeve. After being sleeved on the circumferential cutting groove part of the boring cutter bar, when the boring cutter bar rotates at high speed, the connecting rotating sleeve will not generate a large frictional resistance with the boring cutter bar;

[0039] Side push segmented rod, the housing part of the side push segmented rod is fixedly connected with the inner cavity of the scale sliding housing through a slot. The top of the rod body part of the side push segmented rod is fixedly connected with a heat insulation clamping plate, and the outer surface of the heat insulation clamping plate is mutually extruded with the outer surface of the connecting rotating sleeve;

[0040] Air pressure pump, the top of the air outlet of the air pressure pump is inserted into the housing part of the side push segmented rod. The outer surface of the air pressure pump is sleeved with a bent connecting plate, and the top of the bent connecting plate is fixedly connected with the lower surface of the limiting flat plate. The structures of the air pressure pump and the side push segmented rod are similar to those of the pressure control cylinder and the segmented push rod. They both advance the rod body part of the segmented rod to perform a sliding movement through the pressure control method.

[0041] Furthermore, the heat insulation component includes,

[0042] Liquid suction sleeve ring, on both sides of the liquid suction sleeve ring, there are drainage pipes symmetrically arranged through water inlets. The liquid suction sleeve ring can suck the external coolant into its interior through the internal turbine through the drainage pipes, and then spray the coolant out from the drainage port at the axis;

[0043] Connecting sleeve ring, the top of the connecting sleeve ring is fixedly connected with the bottom of the connecting rotating sleeve, and the inner wall of the liquid suction sleeve ring is sleeved with the outer surface of the connecting sleeve ring;

[0044] Drainage spray pipe, the top of the drainage spray pipe is inserted into the drainage port of the liquid suction sleeve ring. The end part of the drainage spray pipe is lower and is aligned with the boring cutter bar.

[0045] The beneficial effects of the present invention are as follows:

[0046] 1. The device can control the erected cover housing to perform axial rotation through the bottom deflectable thick connecting plate, ensure that the top cutting tool head is always in a vertical state, and can also perform oblique drilling and boring processing on the cylinder head. The thick connecting plate can actively move under the action of the control component, thereby compensating for the distance between the offset cylinder head and the cutting tool head, so that the upper cutting tool head does not need to move significantly, and can also perform oblique drilling and boring processing on the deflected cylinder head. Furthermore, the coverage area of the component used to control the movement of the cutting tool head is reduced to improve the space utilization rate, and the movement path of the cutting tool head will also be greatly shortened, thereby shortening the time required to move the cutting tool head.

[0047] 2. When the cutting tool head is boring the cylinder head, since the thick connecting plate supporting the cylinder head is prone to drive the thick connecting rod to rotate, especially when the thick connecting plate is already deflected, the center of gravity at its top is unstable. Under the drilling impact and vibration of the cutting tool head, the thick connecting plate is very likely to continue to deflect towards the side of the cut slope, resulting in the cutting tool head being unable to stably drill holes in the cylinder head. Therefore, each time the cylinder head is deflected for drilling, the thick connecting plate can be reinforced by the stable component below to prevent the thick connecting plate from deflecting due to the impact force and vibration force, ensuring that the cutting tool head can stably bore and drill holes in the cylinder head.

[0048] 3. After the control box moves to the approximate position and stops moving, then the pneumatic pumps on both sides drive the connecting rotating sleeve, causing the connecting rotating sleeve to drive the cutting tool head to perform a micro-sliding movement relative to the scale sliding housing. The moving distance of the cutting tool head is precisely controlled according to the scale groove of the scale sliding housing. Therefore, under the post-processing effect of the fine-tuning component, the horizontal sliding component does not need to directly move the control box to the specified position, thereby reducing the precision requirement of the horizontal sliding component. So, by sleeving the fine-tuning component, the boring precision of the cutting tool head can be directly improved, avoiding the problem that it is difficult to observe the landing point of the cutting tool head due to the occlusion problem of the horizontal sliding component, resulting in a deviation in the calculation of the moving distance.

[0049] 4. During the boring process, it is necessary to continuously cool the cutting tool head and the cylinder head with coolant to avoid damage to the tool due to overheating. Generally, the coolant is directly sprayed on the connecting part of the tool and the cylinder head. However, the cutting tool head is a metal conductor with strong heat conduction performance. Only cooling the end part of the tool, the top part of the boring tool rod will heat up due to heat conduction, resulting in the circumferential cutting groove and the inserted end part being relatively fragile. Therefore, there is a heat-resistant component. When the boring tool rod is working, the liquid suction sleeve ring flushes the boring tool rod with coolant from top to bottom through the drainage spray pipe, ensuring that the top of the boring tool rod does not heat up. Since the boring tool rod always remains vertical, the boring tool rod also has a drainage effect. The coolant flowing down along the boring tool rod contacts the end and the drilling part of the boring tool rod, thereby achieving the cooling processing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0062] Embodiment 1, please refer to Figures 1 - 5 , the present invention provides a technical solution: a boring device for machining an automobile engine cylinder head, including:

[0063] The boring component 1 is set on the ceiling and is used for boring and drilling the cylinder head below;

[0064] The container bottom box 2 is set on the ground;

[0065] The housing component 4 is set inside the container bottom box 2 and is used for placing the cylinder head;

[0066] The housing component 4 includes:

[0067] The thick connecting plate 41 has a thick connecting rod 42 fixedly installed at the center of the bottom of its inner cavity, and both ends of the thick connecting rod 42 extend to the outside of the thick connecting plate 41. The bottom of the thick connecting plate 41 is of an arc surface structure;

[0068] The control component 5 is symmetrically set on the left and right sides of the thick connecting rod 42 and controls the position of the thick connecting plate 41 through the thick connecting rod 42;

[0069] The top shelf plate 45 is set on the top of the thick connecting plate 41, and the cylinder head is set on the upper surface of the top shelf plate 45;

[0070] Among them, the control component 5 includes:

[0071] The side guide rail 51 has its outer surface fixedly connected to the inner wall of the container bottom box 2. The bottom of the inner wall of the side guide rail 51 is slidably connected with an embedded slider 54 through a chute;

[0072] The deflection motor 55 has its outer surface fixedly connected to the top of the embedded slider 54, and the outer surface of the output shaft of the deflection motor 55 is inserted into the center of the thick connecting rod 42;

[0073] The socket runner 56 has its inner wall rotatably connected to the outer surface of the thick connecting rod 42;

[0074] The transmission belt 52 has electric runners 53 symmetrically set on both sides of its inner wall. The outer surface of the socket runner 56 is in rolling connection with the inner wall of the transmission belt 52, and the outer surface of the transmission belt 52 is in sliding connection with the inner cavity of the side guide rail 51. When the transmission belt 52 rotates, it can drive the socket runner 56 to roll directionally along the side guide rail 51. At this time, relative rotation occurs between the inner wall of the socket runner 56 and the outer surface of the thick connecting rod 42. Therefore, when the socket runner 56 rolls, it can drive the thick connecting plate 41 to slide directionally along the inner wall of the side guide rail 51.

[0075] The housing component 4 also includes,

[0076] Push rod 44 is advanced. Push rod 44 is arranged inside the top shelf 45. The top end of push rod 44 is inserted into the inner wall of the cylinder head through a limiting plug. Push rod 44 can push the rod at the top upward, and then insert it into the interface on the inner wall of the cylinder head. If there is no interface at the corresponding position on the inner wall of the cylinder head, the rod of push rod 44 is retracted into the interior of top shelf 45, making this area on the upper surface of top shelf 45 relatively smooth.

[0077] Side clamping plate 46. The bottom of side clamping plate 46 is slidably connected to the interior of top shelf 45 through a cut notch, and the outer surface of side clamping plate 46 is pressed against the outer surface of the cylinder head.

[0078] Limiting motor 47. The outer surface of limiting motor 47 is fixedly connected to the side of top shelf 45 through an extension frame 43. A threaded push rod is arranged on the outer surface of the output shaft of limiting motor 47, and the end of the threaded push rod away from limiting motor 47 is rotatably connected to the lower part of the outer surface of side clamping plate 46, and the outer surface of the threaded push rod is threadedly connected to the interior of top shelf 45 through a threaded groove.

[0079] It includes a stabilizing component 3, and stabilizing component 3 has:

[0080] Smoothing pressure box 31. The bottom of smoothing pressure box 31 is slidably connected to the bottom of the inner wall of the container bottom box 2.

[0081] Hollow through pipe 32. The bottom end of hollow through pipe 32 is inserted into the interface on the upper surface of smoothing pressure box 31.

[0082] Adhesive arc plate 33. The inner wall of adhesive arc plate 33 is rotatably connected to the bottom of the outer surface of the thick connecting plate 41. Docking notch 34 is evenly arranged in the inner cavity of adhesive arc plate 33. The lower surface of adhesive arc plate 33 is fixedly connected to the top end of hollow through pipe 32 through docking notch 34. The inner wall of adhesive arc plate 33 is always sleeved with the arc surface at the bottom of thick connecting plate 41. When thick connecting plate 41 rotates, the bottom of thick connecting plate 41 will also have relative sliding with the inner wall of adhesive arc plate 33. When smoothing pressure box 31 sucks air into the inner wall of adhesive arc plate 33 through hollow through pipe 32, thick connecting plate 41 will be tightly attached to the inner wall of adhesive arc plate 33 under the adsorption effect, and thus it is difficult to perform sliding movement on the inner wall of adhesive arc plate 33.

[0083] Place the cylinder head of the engine on the upper surface of top shelf 45. According to the actual shape of the inner wall of the cylinder head, extend the corresponding push rod 44 and insert it into the insertion opening on the inner wall of the cylinder head. Then, rotate the threaded rod through the limiting motors 47 on both sides to push the side clamping plates 46 on both sides to move towards the direction close to the side of the cylinder head, clamp the cylinder head, and complete the limiting work of the cylinder head, so that the cylinder head is fixed on the upper surface of top shelf 45.

[0084] The upper boring component 1 uses its cutting tool head 14 to bore the outer surface of the cylinder head. During the process of machining the cylinder head, due to the need for drilling, the cylinder head is drilled obliquely. At this time, the deflection motors 55 on both sides can twist the thick connecting plate 41 through the thick connecting rod 42, causing the upper cylinder head to be inclined relative to the vertically positioned cutting tool head 14. As a result, the cutting tool head 14 can bore an inclined hole. At the same time, the electric rotating wheels 53 on both sides can control the horizontal sliding of the thick connecting plate 41 along the direction of the side guide rail 51 through the transmission belt 52 and the socket rotating wheel 56. Therefore, after the thick connecting plate 41 deflects, the cylinder head can be translated to a position closer to the cutting tool head 14, thus avoiding the problem that the cutting tool head 14 needs to move significantly because the cylinder head is far from the cutting tool head 14 after deflection.

[0085] After the thick connecting plate 41 is bent, the smooth pressurizing box 31 at the bottom needs to adsorb the lower surface of the thick connecting plate 41 through the hollow pipe 32. At this time, the bottom of the thick connecting plate 41 is reinforced and limited, not easily bent, and the stability of the cylinder head during processing is higher. When it is necessary to deflect the thick connecting plate 41, the smooth pressurizing box 31 stops adsorbing the thick connecting plate 41. The bottom of the thick connecting plate 41 can deflect relative to the inner wall of the attached arc plate 33 through its arc surface structure. When the thick connecting plate 41 slides along the side guide rail 51, it will directly pull the smooth pressurizing box 31 along the inner wall of the container bottom box 2 through the attached arc plate 33. Therefore, the attached arc plate 33 is always connected to the bottom of the thick connecting plate 41.

[0086] Example 2, please refer to Figures 1 - 10 , the present invention provides a technical solution: on the basis of Example 1, the boring component 1 includes,

[0087] A horizontal sliding component 11, the upper surface of the horizontal sliding component 11 is arranged on the ceiling;

[0089] A fine-tuning component 6, the fine-tuning component 6 is arranged on the outer surface of the cutting tool head 14 and is used to control the micro-movement of the cutting tool head 14;

[0090] A heat-resistant component 7, arranged below the fine-tuning component 6 and used for cooling the cutting tool head 14.

[0091] The horizontal sliding component 11 includes,

[0092] A limiting flat plate 111, the lower surface of the limiting flat plate 111 is provided with a guiding frame 112;

[0093] The pressure control cylinder 113 has its outer surface slidably connected to the inner cavity of the limiting flat plate 111 through an insertion plate. Moreover, a segmented push rod 114 is inserted on the outer surface of the air outlet of the pressure control cylinder 113. One end of the segmented push rod 114 away from the pressure control cylinder 113 is fixedly connected to a connecting clamping plate 115, and the outer surface of the connecting clamping plate 115 is fixedly connected to the top of the control box 12. The pressure control cylinder 113 makes the segmented push rod 114 extend or contract through pressurization and depressurization, thereby achieving the effect of moving the control box 12 in the plane position.

[0094] The cutting tool head 14 includes,

[0095] An insertion end head 141, the inner cavity of the insertion end head 141 is inserted into the bottom end of the torque end head 13;

[0096] A boring tool bar 142, the top end of the boring tool bar 142 is fixedly connected to the axis center of the inner cavity of the insertion end head 141, and a circumferential cutting groove 143 is opened in the upper part of the outer surface of the boring tool bar 142.

[0097] The fine-tuning component 6 includes,

[0098] A graduated sliding shell 61, a more precise graduated groove is opened at the side part of the graduated sliding shell 61. A connecting rotating sleeve 62 is slidably connected to the inner wall of the graduated sliding shell 61. The inner wall of the connecting rotating sleeve 62 is sleeved on the outer surface of the boring tool bar 142 through the circumferential cutting groove 143. There are balls arranged on the inner wall of the connecting rotating sleeve 62. After being sleeved on the circumferential cutting groove 143 part of the boring tool bar 142, when the boring tool bar 142 rotates at a high speed, the connecting rotating sleeve 62 will not generate a large frictional resistance with the boring tool bar 142;

[0099] A side-pushing segmented rod 65, the shell part of the side-pushing segmented rod 65 is fixedly connected to the inner cavity of the graduated sliding shell 61 through a slot. The top end of the rod body part of the side-pushing segmented rod 65 is fixedly connected to a heat-insulating clamping plate 66, and the outer surface of the heat-insulating clamping plate 66 is mutually pressed against the outer surface of the connecting rotating sleeve 62;

[0100] An air pressure pump 64, the top end of the air outlet of the air pressure pump 64 is inserted into the shell part of the side-pushing segmented rod 65. The outer surface of the air pressure pump 64 is sleeved with a bent connecting plate 63, and the top end of the bent connecting plate 63 is fixedly connected to the lower surface of the limiting flat plate 111. The structures of the air pressure pump 64 and the side-pushing segmented rod 65 are similar to the structures of the pressure control cylinder 113 and the segmented push rod 114, and both are through the way of pressure control to push the rod body part of the segmented rod to carry out a sliding movement.

[0101] The heat-resistant component 7 includes,

[0102] A liquid-absorbing sleeve ring 71, both sides of the liquid-absorbing sleeve ring 71 are symmetrically provided with drainage pipes 72 through water inlets. The liquid-absorbing sleeve ring 71 can suck the external coolant into its interior through the internal turbine through the drainage pipes 72, and then spray the coolant out from the drain port at the axis center;

[0103] The connecting collar 74, the top of the connecting collar 74 is fixedly connected to the bottom of the connecting rotating sleeve 62, and the inner wall of the liquid suction collar 71 is sleeved on the outer surface of the connecting collar 74;

[0104] The drainage spray pipe 73, the top end of the drainage spray pipe 73 is inserted into the drainage port of the liquid suction collar 71, and the end part of the drainage spray pipe 73 is lower, and is aligned with the boring cutter bar 142.

[0105] The horizontal sliding member 11 drives the segmented push rod 114 at the corresponding position to perform elongation or contraction deformation through the pressure control cylinders 113 around it, so as to achieve the effect of pushing the control box 12 in the horizontal direction, driving the cutting tool head 14 to perform a small sliding movement, and cooperating with the sliding action of the rough connecting plate 41, so that the cutting tool head 14 can act on all points of the lower cylinder head. During boring machining, the control box 12 pushes the torque end 13 downward, and at this time the torque end 13 elongates, as Figure 6 shown, the bottom end of the cutting tool head 14 can contact the outer surface of the cylinder head for boring work.

[0106] When the cutting tool head 14 slides down, the cutting tool head 14 will also drive the fine-tuning member 6 and the heat-resistant member 7 to slide down through the connecting rotating sleeve 62. At this time, the top end of the bent connecting plate 63 slides downward relative to the inner cavity of the limiting flat plate 111, but the bent connecting plate 63 is always limited inside the limiting flat plate 111. When higher-precision drilling work needs to be carried out on the cylinder head, the control box 12 stops moving after moving to the approximate position, and then the air pressure pumps 64 on both sides drive the connecting rotating sleeve 62 to make the connecting rotating sleeve 62 drive the cutting tool head 14 to perform a micro-sliding movement relative to the scale sliding shell 61, and accurately control the moving distance of the cutting tool head 14 according to the scale groove of the scale sliding shell 61.

[0107] When the boring cutter bar 142 is working, the liquid suction collar 71 flushes the boring cutter bar 142 with coolant from top to bottom. The coolant can cool the boring cutter bar 142 more comprehensively, so as to ensure that the top of the boring cutter bar 142 does not heat up. Since the boring cutter bar 142 always remains vertical, the boring cutter bar 142 also has a drainage function, and the coolant flowing down along the boring cutter bar 142 contacts the end and drilling parts of the boring cutter bar 142.
