Description

Technical Field

[0001] The invention relates to the technical field of metal cutting tool manufacturing, in particular to a multifunctional hydraulic oil cylinder inner hole machining tool based on joint machining. Background Art

[0002] A compound tool is a tool that combines the functions of two or more different types of tools. It integrates multiple cutting edges on one tool body. The cutting edges can complete different processing procedures. Some compound tools have both a twist drill part for drilling and a reamer part for reaming. They can complete both drilling and reaming processes in one clamping and feeding process.

[0003] With the improvement of industrial automation, the requirements for the processing accuracy of internal components of mechanical equipment are getting higher and higher. In hydraulic devices, hydraulic cylinders are important power transmission devices. The quality of the inner hole of their joint seats directly affects the performance stability and service life of the device. The joint seat is a stepped hole, which is used to connect the hydraulic hose quick interface and is the liquid inlet of the cylinder. The processing process is drilling and reaming, including sealing surfaces. Although the standard tools on the market can meet general processing needs, they are unable to cope with the processing of joint seats with complex shapes and high hardness materials, and it is difficult to meet the requirements of precision processing. Traditional single-edged tools not only have low processing efficiency, but are also easy to wear and cannot be formed in one time, which increases production costs.

[0004] Composite tools increase the number of cutting edges to improve processing speed and surface quality. However, this method is prone to tool chipping due to the large cutting force when processing cemented carbide materials. The existing technology is to design a thick and solid tool body structure, increase the cross-sectional area and moment of inertia of the tool body to improve its ability to resist deformation. In large-diameter composite boring tools, the tool body adopts a thickened cylindrical shape or adds a reinforcing rib structure, which can significantly enhance the rigidity of the tool body. However, when in use, due to its large volume, when the tool is drilling small holes, it cannot adapt to the internal hole processing of different joint seat diameters. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please refer to the attached Figure 1 and attached Figure 5 The embodiment of the present invention provides a multifunctional hydraulic cylinder inner hole processing tool based on joint processing, including a fixed rod 1, a tool 4 is fixedly connected to the left side of the fixed rod 1, a mounting hole 5 is opened at the bottom of the outer wall of the fixed rod 1, a leading rod 6 is fixedly connected inside the mounting hole 5, a plurality of positioning strips 7 are fixedly connected to the outer wall of the leading rod 6, a guide sleeve 8 is slidably connected to the outer wall of the leading rod 6, a plurality of grooves 9 are opened inside the guide sleeve 8, a thread groove 10 is opened on the front side of the guide sleeve 8, an adjusting nut 11 is threadedly connected to the inner part of the thread groove 10, a mounting mechanism 2 is arranged on the top of the outer wall of the fixed rod 1, and a cooling mechanism 3 is arranged on the right side of the fixed rod 1.

[0022] Specifically, the connection between the bottom of the fixed rod 1 and the tool 4 adopts a high-strength connection process of welding. In the face of high-strength cutting force impacts that frequently occur when processing the inner hole of the hydraulic cylinder, the tool 4 is fixed on the fixed rod 1, and always maintains a precise cutting posture, ensuring processing accuracy and avoiding workpiece surface quality problems caused by loosening of the tool 4. The mounting hole 5 at the bottom of the outer wall of the fixed rod 1 provides an installation position for the front guide rod 6 to ensure that the front guide rod 6 can be accurately positioned. The multiple positioning strips 7 on the outer wall of the front guide rod 6 and the grooves 9 inside the guide sleeve 8 form a stable and precise sliding connection mechanism. When the tool 4 shuttles through the inner hole of the hydraulic cylinder for cutting operations, the front guide rod 6 slides smoothly along the guide sleeve 8. The limiting effect of the positioning strips 7 in the grooves 9 makes the movement trajectory of the front guide rod 6 always straight, eliminating the hidden danger of deflection of the tool 4, ensuring processing accuracy and the guide sleeve 8. The combination of the threaded groove 10 and the adjusting nut 11 on the front side, when facing the inner holes of hydraulic cylinders of different specifications, the operator only needs to gently rotate the adjusting nut 11 to easily control the extension length of the leading guide rod 6, and drive the tip of the tool 4 to be quickly and accurately adjusted to the suitable position. Whether it is an inner hole with a narrow diameter that requires fine grinding, or a spacious and open large-diameter inner hole that requires fast cutting, adjustment can be achieved. This convenient adjustment method greatly expands the application scenarios of the tool 4, and greatly enhances its versatility and adaptability. The tool 4 rotates at high speed and cuts accurately under the strong support of the fixed rod 1. The leading guide rod 6 and the guide sleeve 8 ensure that the movement trajectory of the tool 4 is accurate. The adjusting nut 11 is adjusted as needed, so that the tool 4 can operate efficiently under multiple and complex working conditions, and quickly and accurately carve out the inner hole of the hydraulic cylinder that meets high standards, thereby improving processing efficiency and ensuring product quality.

[0023] Please refer to the attached Figure 2 and attached Figure 6 The mounting mechanism 2 includes a connecting plate 201, the bottom of which is fixedly connected to the top of the outer wall of the fixing rod 1, a fixing block 202 is fixedly connected to the top of the connecting plate 201, a circular hole 203 is provided on the left and right sides of the fixing block 202, a spring 204 is fixedly connected inside the two circular holes 203, a clamping block 205 is fixedly connected to the right side of the two springs 204, a limiting column 206 is fixedly connected between the two adjacent clamping blocks 205, a clamping plate 207 is provided on the top of the connecting plate 201, a circular hole 208 is provided on the left and right sides of the clamping plate 207, and a secondary knife body 209 is fixedly connected to the top of the clamping plate 207.

[0024] Specifically, the connection between the right side of the connecting plate 201 and the top of the outer wall of the fixing rod 1 is connected by high-precision welding technology. When the tool 4 is subjected to huge impact and vibration forces during the cutting process, it is ensured that the overall structure does not shake or move at all. The fixing block 202 is located at the top of the connecting plate 201, and a spring 204 is fixedly connected inside the circular hole 203 excavated on the upper and lower sides thereof. The spring 204 is made of an alloy material with elasticity and fatigue resistance. When the auxiliary tool body 209 needs to be installed, the operator steadily pushes the clamping plate 207 toward the fixing block 202, and the circular holes 208 on the left and right sides of the clamping plate 207 gradually approach the clamping block 205. The clamping block 205 feels the pressure from the clamping plate 207 and begins to squeeze the spring 204. The spring 204 contracts, which resolves the rigid collision between the clamping block 205 and the clamping plate 207, avoids damage to the components, and stores elastic potential energy at the same time until the clamping plate 207 accurately reaches the predetermined position. The spring 1 204 uses its elastic restoring force to push the block 205 steadily into the circular hole 208, thereby realizing a close connection between the clamping plate 207 and the fixed block 202. The limiting column 206 ensures that the block 205 is embedded in the circular hole 208 impartially, so that the accuracy and stability of the connection are doubly guaranteed. When the auxiliary tool body 209 needs to be disassembled, the operator only needs to gently press the block 205 to overcome the elastic force of the spring 1 204, and the block 205 will obediently break away from the circular hole 208. The clamping plate 207 without the restraint of the block 205 can be easily disassembled from the fixed block 202. When the auxiliary tool body 209 needs to be replaced, repaired or adjusted, the disassembly and installation operation of the auxiliary tool body 209 is simple and quick, which greatly shortens the time required for the maintenance and replacement of parts of the tool 4, improves the production efficiency, and can maintain good stability and accuracy during multiple disassembly and installation processes, effectively reducing the processing errors caused by frequent replacement of the tool 4.

[0025] Please refer to the attached Figure 1 and attached Figure 7 The cooling mechanism 3 includes a plurality of support rings 302, the left sides of the plurality of support rings 302 are fixedly connected to the right side of the fixed rod 1, a plurality of cooling channels 301 are provided on the right side of the fixed rod 1, a fixing ring 1 303 is fixedly connected to the right side of the plurality of support rings 302, a cooling pipe 304 is fixedly connected inside the plurality of fixing rings 1 303, a filter screen 305 is fixedly connected to the inner left ends of the plurality of cooling pipes 304, a water outlet pipe 306 is connected to the left side of the plurality of cooling pipes 304, and a nozzle 307 is fixedly connected to the left side of the plurality of water outlet pipes 306.

[0026] Specifically, a plurality of cooling channels 301 are provided on the top of the fixed rod 1, and a plurality of support rings 302 are fixedly connected on the left side to the right side of the fixed rod 1. The support rings 302 are evenly distributed, providing a stable support force for the upper fixed ring 1 303. The cooling pipe 304 fixedly connected inside the fixed ring 1 303 is a path for the circulation of the coolant. The coolant flows into the cooling pipe 304 under the drive of the external power device. The filter net 305 at the bottom of the inner side of the cooling pipe 304 plays a filtering role, which can effectively intercept the impurity particles in the coolant and prevent it from being blocked at the nozzle 307, ensuring that the coolant can be smoothly sprayed onto the tool 4. When the processing starts, the coolant flows in the cooling pipe 304, taking away the heat generated by the cutting process. The coolant passing through the cooling pipe 304 finally flows to the nozzle 307 through the outlet pipe 306 connected on the left side. The nozzle 3 07 The spray angle and range can fully cover the key parts of the tool 4. The coolant is evenly sprayed on the surface of the tool 4 in the form of mist or thin stream from the nozzle 307, and the temperature of the tool 4 is quickly reduced through heat exchange. The combined design of multiple cooling channels 301 and cooling tubes 304 increases the contact area between the coolant and the tool 4 and the heat exchange efficiency, which can more effectively reduce the temperature of the tool 4 and reduce the wear and deformation of the tool 4 caused by overheating, thereby extending the service life of the tool 4. The setting of the filter 305 ensures the long-term stable operation of the cooling device and reduces the frequency of maintenance due to blockage. The reasonable layout of the nozzle 307 ensures that all parts of the tool 4 can be fully cooled, improves the uniformity of cooling, and helps to maintain the stable performance of the tool 4 during the processing process, thereby improving the accuracy and surface quality of the hydraulic cylinder inner hole processing.

[0027] Please refer to the attached Figure 1 A fixing plate 12 is fixedly connected to the middle of the front side of the fixing rod 1 , and a warning sign 13 is fixedly connected to the front side of the fixing plate 12 .

[0028] Specifically, the fixing plate 12 in the middle of the front side of the fixing rod 1 and the warning sign 13 thereon play an important role. The fixing plate 12 is made of a strong and lightweight alloy material, and is tightly connected to the fixing rod 1 by welding or high-strength bolts to ensure stability during the processing. The warning sign 13 is usually in a striking yellow or red background color, with warning information marked in black bold font. Before the machine tool is started, the operator can clearly see the warning sign 13, always reminding himself to pay attention to operating safety, avoid safety accidents caused by negligence, and ensure the smooth progress of the processing process.

[0029] Please refer to the attached Figure 3 and attached Figure 4 A plurality of connecting rods 14 are fixedly connected to the left side of the outer wall of the fixing rod 1, and a fixing ring 2 15 is fixedly connected to the top of each of the plurality of connecting rods 14.

[0030] Specifically, multiple connecting rods 14 are made of solid metal material and are welded to the fixed rod 1 to ensure the stability of the connection. The fixing ring 15 on the top accurately surrounds the outside of the cooling tube 304, and the cooling tube 304 is firmly fixed by welding or tight fit. During the processing, this fixing method can effectively prevent the cooling tube 304 from being displaced or loosened due to vibration or external force, ensuring that the coolant circulates stably in the cooling tube 304, thereby continuously providing efficient cooling effect for the tool 4, maintaining the normal working temperature of the tool 4, and extending the service life of the tool 4.

[0031] Please see attached Figure 1 and attached Figure 4 The bottom of the front guide rod 6 is fixedly connected with a circular plate 16, and the circular plate 16 is of smooth design.

[0032] Specifically, the rounded shape of the circular plate 16 at the bottom of the front guide rod 6 can not only play a guiding role when the tool 4 enters the inner hole of the workpiece, but also effectively prevent the guide sleeve 8 from accidentally moving away from the front guide rod 6. The circular plate 16 is tightly connected to the front guide rod 6 and is made of high-strength alloy material to ensure that it remains stable in complex processing environments. During processing, the guide sleeve 8 slides on the front guide rod 6. When subjected to external force or vibration, the circular plate 16 can prevent the guide sleeve 8 from excessively displacing to the right through its appropriate size and smooth edges, thereby maintaining the relative position relationship between the front guide rod 6 and the guide sleeve 8 stable, thereby ensuring the normal operation and processing accuracy of the tool 4.

[0033] Please see attached Figure 8 The left and right sides of the locking plate 207 are both provided with slots 17 , and the insides of the two slots 17 are both fixedly connected with springs 18 .

[0034] Specifically, the clamping plate 207 is made of high-strength aluminum alloy, and the notches 17 on the left and right sides thereof are finely processed, with precise dimensions and smooth surfaces. The spring 2 18 inside the notch 17 is wound with high-elastic alloy steel wire and has good elastic recovery ability. During the installation of the tool 4, when the clamping plate 207 cooperates with other components, the spring 2 18 can play a role of buffering and fine-tuning, ensuring the smoothness and accuracy of the clamping process, while compensating for the slight dimensional deviations between components to a certain extent, thereby enhancing the stability and reliability of the entire tool 4 structure.

[0035] Please see attached Figure 8 The right sides of the two springs 18 are fixedly connected with an extrusion plate 19 , and the adjacent extrusion plates 19 are fixedly connected with an extrusion column 20 .

[0036] Specifically, when it is necessary to operate the block 205, an external force acts on the extrusion plate 19. Due to the elasticity of the spring 218, the extrusion plate 19 can squeeze the block 205 inward, and the extrusion column 20 ensures the synchronous movement of the two extrusion plates 19, so that the block 205 is subjected to a uniform extrusion force. During the disassembly of the tool 4, by pressing the extrusion plate 19, the spring 218 contracts, driving the extrusion column 20 to push the block 205 out of the matching component, thereby realizing fast and convenient disassembly operation, and improving the efficiency and convenience of maintaining the tool 4.

[0037] Please see attached Figure 5 The adjacent positioning strips 7 are fixedly connected to the outer wall of the leading rod 6 at equal distances, and the plurality of grooves 9 correspond to the leading rod 6 .

[0038] Specifically, the positioning strip 7 is made of high-strength alloy steel and is equidistantly and firmly attached to the outer wall of the leading rod 6 through a welding process. Its precise spacing and straight shape ensure the stability of the leading rod 6 during movement. The groove 9 in the guide sleeve 8 is precisely machined according to the size of the leading rod 6 and the distribution of the positioning strip 7. The two fit closely together, and when the tool 4 is working, it can effectively prevent the leading rod 6 from shifting or shaking, so that the tool 4 always runs along the predetermined trajectory, thereby greatly improving the accuracy and quality of the inner hole machining of the hydraulic cylinder.

[0039] Please see attached Figure 7 , multiple cooling channels 301 are evenly spaced apart on the right side of the fixing rod 1 , and the outer walls of multiple cooling pipes 304 are evenly spaced apart and fixedly connected to the inside of the cooling channels 301 .

[0040] Specifically, the cooling channel 301 is opened equidistantly on the right side of the fixed rod 1 by high-precision processing technology to ensure that the coolant can be evenly distributed. The cooling pipe 304 is made of metal material with good thermal conductivity, and its outer wall is equidistantly fixed inside the cooling channel 301 by welding or a special sealing connection method to ensure that the coolant will not leak during the circulation process and can fully exchange heat with the fixed rod 1, so that all parts of the tool 4 can be evenly cooled during the processing, effectively reducing the temperature of the tool 4, extending the service life of the tool 4, and improving the processing accuracy.

[0041] Working principle: The high-strength welding connection between the fixed rod 1 and the tool 4 can effectively resist the strong force generated during the cutting process. The mounting hole 5 can accurately determine the installation position of the leading rod 6, ensuring that the relative position between the leading rod 6 and the fixed rod 1 is always stable. The positioning strip 7 on the outer wall of the leading rod 6 and the groove 9 inside the guide sleeve 8 fit each other to form a sliding structure. When the tool 4 starts to be put into the processing work of the inner hole of the hydraulic cylinder, as it moves in the hole, the leading rod 6 will slide accordingly in the guide sleeve 8. Under the restriction of the groove 9, the positioning strip 7 can only move along a predetermined specific direction. The positioning strip 7 sets a precise track for the leading rod 6 to ensure its linear motion trajectory, so that the tool 4 will not deflect, improve the processing accuracy, control the dimensional error within a very small range, and greatly reduce the waste caused by the deflection of the tool 4, effectively saving production costs and improving production efficiency. The cooperation between the adjusting nut 11 and the threaded groove 10 of the guide sleeve 8 adds strong adaptability to the tool 4. When faced with the processing needs of hydraulic cylinder inner holes of different diameter specifications, the operator only needs to manually rotate the adjusting nut 11 to change its position in the thread groove 10. Due to the close mechanical linkage between the adjusting nut 11 and the leading rod 6, the change in the position of the adjusting nut 11 will directly drive the corresponding change in the extension length of the leading rod 6, thereby enabling the tip position of the tool 4 to be accurately adjusted, allowing the tool 4 to quickly adapt to various processing scenarios, greatly broadening its application range, so that it can be adjusted whether it is to cope with the fine cutting required for small-diameter inner holes or the rapid removal of materials for large-diameter inner holes. With the strong support of the fixed rod 1, the tool 4 maintains a high-speed rotation state for cutting operations, and the leading rod 6 and the guide sleeve 8 ensure that the movement accuracy of the tool 4 meets the requirements. As long as the processing requirements change, the adjusting nut 11 can be immediately adjusted accordingly, so that the tool 4 can not only efficiently remove the excess material in the inner hole of the hydraulic cylinder, but also ensure that the surface of the inner hole after processing has an ideal roughness, and the dimensional accuracy fully meets the relevant standard requirements.

[0042] At the same time, the connecting plate 201 and the fixing rod 1 are firmly connected by welding, so that the connecting part of the connecting plate 201 and the fixing rod 1 forms a seamless and high-strength combination. During the processing of the tool 4 running at high speed and bearing huge cutting force, the two are always closely connected without any relative displacement. When the auxiliary tool body 209 needs to be installed, the clamping plate 207 is pushed toward the fixing block 202. As the clamping plate 207 gradually approaches, it contacts the clamping block 205, and the clamping block 205 is subjected to the clamping plate 207. 07, the spring 1 204 contracts inward under pressure, avoiding surface wear, deformation or even damage caused by rigid collision between the clamping block 205 and the clamping plate 207, thereby extending the service life of the components. The spring 1 204 stores elastic potential energy during the compression process. When the clamping plate 207 accurately reaches the predetermined position, the spring 1 204 releases the stored elastic potential energy, pushing the clamping block 205 to accurately embed into the circular hole 208, thereby achieving a stable connection between the clamping plate 207 and the fixing block 202. In this process, the limit The positioning post 206 accurately defines the displacement boundary of the block 205, ensuring that the block 205 can be embedded in the second circular hole 208 under the push of the spring 1 204, eliminating the hidden danger of loose connection caused by a slight deviation in the position of the block 205. When the auxiliary blade body 209 needs to be disassembled, it is only necessary to press the block 205 hard to overcome the elastic force of the spring 1 204, and the block 205 will be separated from the second circular hole 208. The clamping plate 207 loses the restraint of the block 205 and can be easily removed from the fixed block 202, and the whole The disassembly process is smooth and easy. When the auxiliary tool body 209 needs to be replaced, repaired or adjusted, the operator can quickly complete the relevant operations, which greatly shortens the downtime and significantly improves the production efficiency. Even after repeated disassembly and installation, it can still maintain good accuracy. After the tool 4 is replaced, there is no need to frequently make fine adjustments to the processing parameters, which effectively reduces the processing error introduced by the replacement of the tool 4, ensures the consistency of the processing quality of the inner hole of the hydraulic cylinder, and provides a solid guarantee for large-scale and high-precision production.

[0043] In addition, the multiple cooling channels 301 designed on the right side of the fixed rod 1 have built a basic framework for the transmission and distribution of the coolant. The cooling channel 301 is made by a high-precision machining process, and its internal surface is smooth to ensure that the coolant can flow smoothly and unimpeded. The multiple support rings 302 closely connected thereto are evenly distributed around the cooling channel 301 and are made of a high-strength material with good thermal conductivity, so that the fixed ring 303 can carry the cooling pipe 304 and also assist in heat dissipation to a certain extent. When the external power device is started, the coolant is driven by pressure and quickly flows into the cooling pipe 304. The filter screen 305 at the bottom of the inner side of the cooling pipe 304 is made of a fine metal wire mesh or a polymer material. The mesh size is accurately calculated and can accurately intercept various impurity particles mixed in the coolant, whether it is metal debris, oil stains, or tiny dust generated during the processing process. If there is no filter screen 305, the impurities will flow to the nozzle 307 with the coolant and gradually accumulate at the nozzle 307, leading to The coolant is blocked from spraying and cannot be sprayed evenly on the tool 4, which ultimately greatly reduces the cooling effect. During the processing of the tool 4 running at high speed, there is intense friction between the tool 4 and the workpiece, generating a large amount of heat. The coolant circulates continuously in the cooling pipe 304, constantly absorbing the heat emitted by the tool 4. The coolant that has absorbed the heat smoothly reaches the nozzle 307 through the outlet pipe 306. The spray angle and range of the nozzle 307 are designed according to the shape, size and key heating parts of the tool 4, and can cover the key parts of the cutting edge and the blade surface of the tool 4 in all directions and without dead ends. When the coolant is sprayed evenly on the surface of the tool 4 in a thin stream from the nozzle 307, the cooling effect is further enhanced. This uniform cooling method ensures that the temperature of each part of the tool 4 is balanced, and there will be no hot spots of local overheating, which maintains the stable performance of the tool 4 during the processing. When processing the inner hole of the hydraulic cylinder, it can cut more accurately, avoiding the softening and deformation of the tool 4 caused by local overheating, thereby affecting the processing accuracy and surface quality.
