Description

Technical Field

[0001] This invention relates to the field of long rod processing technology, and in particular to a rapid grooving and drilling machine for forming steps in long rods, as well as a forming method therefor. Background Technology

[0002] Carbon fiber rods and glass fiber rods, as high-performance composite rods, have advantages such as being lightweight, high-strength, corrosion-resistant, and anti-aging, and are widely used in modern industry and high-end applications.

[0003] In the manufacturing process using long, rod-shaped carbon fiber rods and glass fiber rods, the processing involves multiple steps such as grooving, end drilling, and machining stepped surfaces at different locations. This requires multiple machines to process the materials sequentially. Each change of processing equipment necessitates a positioning process, making the operation cumbersome and difficult to achieve in a single, complete forming. This results in low processing efficiency, increasing production costs and extending the processing cycle. Furthermore, because the raw materials are slender rods, they are prone to deformation during multiple assembly processes. Errors caused by repeated manual assembly and positioning can easily affect the mechanical properties of the product and make it difficult to guarantee the dimensional accuracy of the finished product.

[0064] like Figures 1 to 11 The equipment and method for rapid grooving and drilling of long rods to form steps include:

[0065] The synchronous grooving mechanism 10 is provided with a first processing station 10a, which is used to perform a one-time grooving operation on the outer axial surface of the long rod.

[0066] The drilling step mechanism 20 is provided with a second processing station 20a, which is used to perform drilling and step turning operations on the end of the long rod.

[0067] The transition mechanism 30 is located between the synchronous grooving mechanism 10 and the drilling step mechanism 20, and is used to transfer the long rod from the first processing station 10a to the second processing station 20a.

[0068] The synchronous grooving mechanism 10 includes a first base 11 and a feeding bracket 121, a first clamping block 131, a second clamping block 132, a first fixing head 141, a clamping head 142, a plurality of grooving cutter positions 151, and a recycling tank disposed on the first base 11.

[0069] The feeding bracket 121 is inclined toward the side where the first processing station 10a is located. The first clamping block 131 and the second clamping block 132 are both located at the top of the first processing station 10a. Multiple second clamping blocks 132 are arranged along the length of the first clamping block 131. Each second clamping block 132 is hinged to the first clamping block 131. The first clamping block 131 and the second clamping block 132 form an open arc-shaped groove 13a on the side facing the feeding bracket 121. The long rod that slides down from the feeding bracket 121 is received in the arc-shaped groove 13a. The first fixing head 141 and the clamping head 142 are located at both ends of the long rod and form a fixed clamping effect on both ends of the long rod. Several slotted cutting positions 151 are arranged sequentially along the axial direction of the long rod and can be away from or close to the outer axial surface of the long rod. The recycling groove is located at the bottom of the first processing station 10a and is inclined toward the side where the transition transfer mechanism 30 is located.

[0070] The drilling step mechanism 20 includes a second base and a second fixed head 211, a guide tube 212, and multiple machining tools disposed on the second base;

[0071] The guide tube 212 is arranged along the axial direction of the long rod body. The second fixing head 211 is arranged at one end of the guide tube 212. The long rod body passes through the guide tube 212, and the second fixing head 211 clamps and fixes the end of the long rod body. Multiple machining tools are arranged on the second machining station 20a, located on the side of the long rod body facing the second fixing head 211. Any machining tool can move away from or towards the outer axial surface of the long rod body.

[0072] The transition and transfer mechanism 30 includes a transition chamber 311, a transfer platform 321, and a synchronous push rod 322;

[0073] The transition chamber 311 moves back and forth between the recovery tank and the transfer platform 321. The transfer platform 321 is located at the end of the conduit 212 away from the second fixed head 211. The synchronous push rod 322 is slidably disposed on the transfer platform 321 and is coaxially disposed with the conduit 212.

[0074] By integrating the synchronous grooving mechanism 10 and the drilling step mechanism 20, the long rod body can be grooved and drilled at the end, and the step turning operation can be realized in one go. This reduces the need for multiple changes of processing equipment and repeated positioning, and significantly improves processing efficiency. Moreover, it realizes automated assembly and processing, reduces manual operation, and reduces dimensional deviation caused by human operation error, thereby ensuring the dimensional accuracy of the processed product and ensuring the stability of the product's mechanical properties.

[0075] The process of forming a long rod using a rapid grooving and drilling lathe for step processing includes the following steps: Several long rods are arranged sequentially on a loading support 121; the long rod in the first position on the loading support 121 falls under its own weight and is received in the arc-shaped groove 13a of the first clamping block 131 and the second clamping block 132; the first fixing head 141 and the clamping head 142 provide a fixed clamping effect on both ends of the long rod and drive the long rod to rotate around its axial direction; several grooving tool positions 151 move to their respective processing positions to perform a one-time grooving operation on the outer axial surface of the long rod; several grooving tool positions 151... 51 Reset: The first fixing head 141 and chuck 142 release their clamping action on the long rod, allowing the long rod to be released into the recovery tank; the transition chamber 311 receives the long rod and transfers it to the transfer platform 321; the end face of the synchronous push rod 322 abuts against the end face of the long rod and pushes the long rod to move into the guide tube 212; the second fixing head 211 clamps and fixes the long rod, selects the corresponding machining tool and moves it to the second machining station 20a, and sequentially performs end drilling and step turning operations; the second fixing head 211 releases its clamping and fixing action on the long rod, completing the external machining of a single long rod.

[0076] The inclined design of the feeding bracket 121 facilitates the automatic sliding and positioning of the long rod, simplifying the feeding process. The design of the clamping block and chuck 142 provides a stable clamping effect, ensuring the stability of the long rod during processing. The movable design of the grooving tool position 151 makes the grooving operation more flexible and precise, and the position of the grooving tool position 151 can be adjusted according to different length and quantity requirements. The design of the guide tube 212 and the second fixing head 211 ensures the accuracy of the connection between the guide tube 212 and the long rod during the transfer process, thereby ensuring the precise alignment of the fixed end processing and improving the accuracy of drilling and step turning.

[0077] Based on the above embodiments, the synchronous grooving mechanism 10 includes a feeding component 12, which is located on one side of the top of the first processing station 10a and includes a feeding bracket 121, an angle adjustment support 122, a material stop cylinder 123, and a material stop plate 124.

[0078] The feeding bracket 121 includes a base frame 121a, a base plate 121b, a baffle 121c, and a transition support plate 121d. The base frame 121a is fixedly installed on the top of the first base 11. The two ends of the base plate 121b are fixedly connected to the top of the base frame 121a and are inclined towards the side where the first processing station 10a is located. There are two baffles 121c, which are respectively vertically installed at both ends of the base plate 121b. There are multiple transition support plates 121d, which are arranged sequentially along the length of the base plate 121b. An angle adjustment support 122 is installed on the top of the base frame 121a, and the side of the base plate 121b away from the baffle 121c is rotatably connected to the angle adjustment support 122.

[0079] The stop cylinder 123 is located on the side of the feeding bracket 121 facing the first processing station 10a. The stop plate 124 is set at the output end of the stop cylinder 123 and is set opposite to the long rod on the transition support plate 121d.

[0080] The design of the loading assembly 12 makes loading long rods more convenient and automated, reducing manual operation and improving loading efficiency. Specifically, the structure of the base frame 121a, base plate 121b, baffle 121c, and transition support plate 121d provides stable support, ensuring the stability of the long rods during the loading process and reducing the risk of accidents caused by the sliding or tipping of the long rods. The tilt angle of the base plate 121b can be adjusted by the angle adjustment support 122 to accommodate long rods of different lengths and diameters, increasing the adaptability and flexibility of the equipment. The stop cylinder 123 and the stop plate 124 are used to control the movement of the long rods, ensuring that the long rods enter the processing station in a predetermined order and at predetermined intervals, preventing the long rods from piling up or misaligning, and improving the accuracy and safety of processing.

[0081] Based on the above embodiments, the synchronous grooving mechanism 10 includes a moving component 13, which is located at the top of the first processing station 10a and is arranged opposite to the feeding component 12. It includes a first clamping block 131, a second clamping block 132, a support frame 133, a moving cylinder 134, a guide rod 135, and a guide sleeve 136.

[0082] The support frame 133 is located at the top of the first processing station 10a. The moving cylinder 134 is located on the support frame 133 and its output end is fixedly connected to the first clamping block 131. Multiple pairs of guide sleeves 136 and guide rods 135 are provided. The guide sleeves 136 are fixedly located on the support frame 133 along the extension and retraction direction of the moving cylinder 134. The guide rods 135 are slidably located in the corresponding guide sleeves 136 and one end is fixedly connected to the side of the first clamping block 131 away from the second clamping block 132.

[0083] The design of the moving component 13 allows the first clamping block 131 to be precisely adjusted in position according to processing needs, improving processing flexibility and adaptability. Specifically, the cooperation of the first clamping block 131 and the second clamping block 132 can stably fix the long rod, ensuring the accuracy of its position when the long rod is transferred between the first fixed head 141 and the clamping head 142, thereby ensuring the accuracy of the positioning of the long rod and the grooving tool position 151 during the grooving process and thus ensuring processing accuracy. The support frame 133 provides a stable support for the moving cylinder 134 and the clamping blocks, ensuring the stability of the moving component 13 during operation. The extension and retraction of the moving cylinder 134 can drive the first clamping block 131 and the second clamping block 132 to move synchronously, achieving precise acceptance and transfer of the long rod and improving processing efficiency. The cooperation of the guide rod 135 and the guide sleeve 136 not only improves the guiding accuracy of the moving component 13, but also reduces friction during the movement, making the movement process smoother and more precise.

[0084] Based on the above embodiments, the synchronous grooving mechanism 10 includes a clamping assembly 14, which is distributed at both ends of the first processing station 10a and includes a first fixed head 141, a chuck 142, a first clamping seat 143, a first clamping cylinder 144, a first fixed sleeve 145, a first adapter sleeve 146, and a tailstock 147.

[0085] The first clamping seat 143 and the tail seat 147 are respectively disposed at both ends of the long rod body. The first fixing head 141 and the clamp 142 are respectively disposed on the opposite side of the first clamping seat 143 and the tail seat 147. The tail seat 147 can move back and forth along the axial direction of the long rod body and drive the long rod body to rotate around the axis.

[0086] The first fixed sleeve 145 is disposed in the first clamping seat 143 and is movably connected to the first fixed head 141. The first adapter sleeve 146 is sleeved on the end of the first fixed sleeve 145 away from the first fixed head 141. The first clamping cylinder 144 is rotatably disposed on one side of the first clamping seat 143, and its output end is rotatably connected to the first adapter sleeve 146.

[0087] The design of the clamping assembly 14 ensures the stability of the long rod during processing and prevents processing errors caused by positional deviations of the long rod. Specifically, the first fixed head 141 and the chuck 142 are located on opposite sides of the first clamping seat 143 and the tailstock 147, providing stable fixing and clamping functions to ensure that the long rod will not undergo axial displacement during processing. The tailstock 147 can reciprocate along the axial direction of the long rod, which allows the clamping assembly 14 to adapt to long rods of different lengths, increasing the flexibility of the equipment. Through the extension and retraction of the first clamping cylinder 144, the relative movement of the first adapter sleeve 146 and the first fixed sleeve 145 is driven, thereby quickly realizing the clamping and release action of the first fixed head 141 on the end of the long rod, improving processing efficiency and accuracy.

[0088] Based on the above embodiments, the synchronous grooving mechanism 10 includes a grooving component 15 and an auxiliary component 16 arranged opposite to each other along the feeding direction of the long rod, and the grooving component 15 is arranged on the side close to the transition transfer mechanism 30.

[0089] The grooving assembly 15 includes several grooving cutter positions 151 and a first displacement stage 152. Multiple first displacement stages 152 are provided and slidably disposed on the top of the first base 11. Each first displacement stage 152 has at least one grooving cutter position 151 on its top. The displacement stage drives the grooving cutter position 151 to move along the axis or radial direction of the long rod.

[0090] The auxiliary component 16 includes several second displacement stages 161 and support blocks 162 disposed on the second displacement stages 161. Each support block 162 is inclined toward the first processing station 10a and has a receiving wheel 163 at its end. The receiving wheel 163 abuts against the side of the long rod facing the recycling tank.

[0091] The grooving assembly 15 can efficiently perform grooving operations on the long rod, while the auxiliary assembly 16 provides stable support and guidance for the long rod, ensuring the stability and accuracy of the processing. Specifically, by setting multiple first displacement stages 152, simultaneous grooving operations can be performed on multiple positions of the long rod, improving the flexibility and efficiency of the processing. The grooving tool position 151 can move along the axis or radial direction of the long rod, which allows for precise grooving of different parts of the long rod as needed. The support block 162 and receiving wheel 163 on the auxiliary assembly 16 provide stable support for the grooving process of the long rod, ensuring that the long rod will not shift or vibrate during processing, and also assisting the long rod to fall smoothly into the recycling tank below, ensuring the stability of the overall processing.

[0092] Based on the above embodiments, the drilling step mechanism 20 includes a fixing component 21 and a processing component 22, with the fixing component 21 located between the transition mechanism 30 and the processing component 22.

[0093] The fixing assembly 21 includes a second fixing head 211, a guide tube 212, a second clamping seat 213, a second clamping cylinder 214, a second fixing sleeve 215, and a second adapter sleeve 216;

[0094] The second fixing head 211 is disposed at one end of the second clamping seat 213 away from the transition transfer mechanism 30. The second fixing sleeve 215 is disposed in the second clamping seat 213 and is movably connected to the second fixing head 211. The second adapter sleeve 216 is sleeved on one end of the second fixing sleeve 215 away from the second fixing head 211. The second clamping cylinder 214 is rotatably disposed on one side of the second clamping seat 213, and its output end is rotatably connected to the second adapter sleeve 216.

[0095] The machining component 22 includes multiple machining tools and a machining table 221. The multiple machining tools are arranged side by side on the machining table 221, and when the machining tools are located at the machining position of the machining table 221, they are positioned opposite to the end face of the long rod.

[0096] The design of the fixing component 21 ensures the stability of the end of the long rod during processing, preventing processing errors caused by movement or vibration of the long rod. The cooperation between the second fixing head 211 and the guide tube 212 can accurately receive the long rod from the transition transfer mechanism 30 and form a stable fixing effect on the end of the long rod, ensuring that the long rod will not be displaced during drilling and step turning operations. The extension and retraction of the second clamping cylinder 214 drives the second adapter sleeve 216 to move, thereby transmitting the movement to the second fixing head 211 through the second fixing sleeve 215, forming a precise clamping and release action on the long rod. Multiple processing tools are arranged side by side on the processing table 221, which can perform drilling and step turning operations on the end of the long rod according to the processing sequence, improving the flexibility and efficiency of processing.

[0097] Based on the above embodiments, the transition transfer mechanism 30 includes a transition component 31, which is disposed opposite to the recovery tank and includes a transition chamber 311, a lifting bracket 312, a lifting rod 313, and a lifting sleeve 314.

[0098] The lifting bracket 312 is fixedly connected to the end face of the second base. The axial direction of the lifting rod 313 is set along the height direction of the lifting bracket 312. The lifting sleeve 314 is slidably sleeved on the outer shaft surface of the lifting rod 313. The side of the transition chamber 311 away from the recovery tank is fixedly connected to the lifting sleeve 314.

[0099] The design of the transition component 31 enables the automatic transfer of the long rod from the first processing station 10a to the second processing station 20a, improving transfer efficiency and automation. Specifically, the transition chamber 311 is fixedly connected to the lifting sleeve 314 on the side opposite to the recovery tank, allowing the transition chamber 311 to move with the lifting sleeve 314, facilitating the transfer of the long rod from the recovery tank to the transfer platform 321. The lifting bracket 312 is fixedly connected to the end face of the second base, providing stable support and ensuring the stability and safety of the lifting process. The lifting rod 313 is set along the height direction of the lifting bracket 312, and the lifting sleeve 314 is slidably sleeved on the outer axial surface of the lifting rod 313, allowing the transition chamber 311 to move smoothly up and down along the lifting rod 313, thereby ensuring the stability of the long rod during the transfer process.

[0100] Based on the above embodiments, the transition chamber 311 includes a connecting frame 311a, a U-shaped support plate 311b, a side plate 311c, a first connecting block 311d, a second connecting block 311e, and an adjusting rod 311f. The connecting frame 311a is fixedly connected to the lifting slide sleeve 314. A U-shaped groove 311g is provided on the top of the connecting frame 311a. The first connecting block 311d is fixedly connected to the top of both ends of the U-shaped support plate 311b. The second connecting block 311e is fixedly connected to both ends of the side plate 311c. The second connecting block 311e is disposed in the U-shaped groove 311g. The first connecting block 311d and the second connecting block 311e are connected by the adjusting rod 311f. The height between the first connecting block 311d and the second connecting block 311e is adjustable.

[0101] The U-shaped pallet 311b provides a stable platform for supporting and transferring long rods. Its U-shaped structure helps to fix the long rods and prevent jamming caused by axial displacement during transfer, ensuring the stability of the transfer. The adjusting rod 311f between the first connecting block 311d and the second connecting block 311e allows for adjustable height settings. When the transition chamber 311 moves to the top, the U-shaped pallet 311b drives the long rods to extend and move upwards further, creating relative displacement with the side plate 311c. This provides space for further transfer of the long rods and ensures the continuity of the transfer process.

[0102] Based on the above embodiments, the transition transfer mechanism 30 includes a transfer component 32, which is arranged opposite to the drilling step mechanism 20 and includes a transfer platform 321, a synchronous push rod 322, an inclined guide plate 323, a guide bar 324, a positioning plate 325, an adjusting plate 326, an adjusting cylinder 327, and a stop bar 328.

[0103] Two inclined guide plates 323 are provided, located at both ends of the long rod. Each inclined guide plate 323 has a guide bar 324 vertically installed on the bottom of the opposite side. Each guide bar 324 has a positioning plate 325 installed at the end away from the transition chamber 311. The length direction of the adjusting plate 326 is set along the axis of the long rod. Both positioning plates 325 are locked on the side of the positioning plate 325 away from the transition chamber 311. The output end of the adjusting cylinder 327 is fixedly connected to the adjusting plate 326. The baffle 328 has an L-shaped cross section and is fixedly installed on the transfer platform 321 at one end. The side of the guide bar 324 facing the baffle 328 forms an arc-shaped guide surface. The baffle 328 is set opposite to the side of the positioning plate 325 and the inclined guide plate 323 to form a transfer gap. The transfer gap is set on the axis of the guide tube 212.

[0104] The top of the side plate 311c is provided with two positioning grooves 311h. The ends of the two guide bars 324 that are away from the positioning plate 325 extend to the outside of the inclined guide plate 323 to form positioning heads 324a. The positioning heads 324a and the positioning grooves 311h at the same end are located on the same vertical plane, and the positioning heads 324a are abutted against the positioning grooves 311h.

[0105] The design of the transfer assembly 32 ensures precise transfer of the long rod from the transition chamber 311 to the drilling step mechanism 20, improving transfer efficiency and automation. Specifically, when the long rod extends above the side plate 311c, the inclined guide plate 323 and guide bar 324 provide stable guidance for the long rod. Both ends of the long rod are supported by the guide bar 324 and move through the inclined guide bar 324 to contact the stop bar 328, and then enter the transfer gap along the arc-shaped guide surface. At this time, the end face of the synchronous push rod 322 is opposite to the end face of the long rod, and the synchronous push rod 322 moves along the axial direction toward the drilling step mechanism 20. The long rod is pushed into the guide tube 212 to complete the transfer process. During this process, the extension and retraction of the cylinder 327 causes the adjusting plate 326 and the positioning plates 325 at both ends to move relative to each other in the height direction, thereby changing the inclination of the guide bar 324 toward the transfer platform 321 and thus controlling the speed at which the long rod enters the transfer gap. The L-shaped cross-section design of the stop bar 328 provides a stable guide for the long rod, ensuring that the end of the long rod can be in a state of relative arrangement with the end face of the synchronous push rod 322 after entering the transfer gap, and that the long rod can move out of the transfer gap in a straight line, ensuring the accuracy of the movement path during the transfer process.

[0106] like Figure 12 As shown, the present invention also provides a method for forming steps using a rapid grooving and drilling machine for long rods, which utilizes the aforementioned rapid grooving and drilling machine for forming steps, and includes the following steps:

[0107] Several long rods are arranged sequentially on the feeding bracket 121;

[0108] The long rod located in the first position of the feeding bracket 121 falls by its own weight and is supported in the arc-shaped groove 13a of the first clamping block 131 and the second clamping block 132;

[0109] The first fixing head 141 and the clamp 142 form a fixing clamp on both ends of the long rod and drive the long rod to rotate around the axis;

[0110] Several grooving tool positions 151 move to their respective corresponding machining positions to perform a one-time grooving operation on the outer shaft surface of the long rod;

[0111] Several slotting cutter positions 151 are reset, and the first fixing head 141 and the chuck 142 release their fixing and clamping effect on the long rod, allowing the long rod to be released into the recycling tank.

[0112] The transition chamber 311 receives the long rod and transfers it to the transfer platform 321. The end face of the synchronous push rod 322 abuts against the end face of the long rod and pushes the long rod into the guide tube 212.

[0113] The second fixing head 211 clamps and fixes the long rod, selects the corresponding machining tool and moves it to the second machining station 20a, and performs end drilling and step turning operations in sequence.

[0114] The second fixing head 211 releases its clamping and fixing function on the long rod, completing the external processing and shaping of the single long rod.

[0115] The specific process of the above-mentioned method for rapid grooving and drilling of long rods to form steps has been described in detail in the above embodiments, and will not be repeated here.
