Detailed Implementation

[0043] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0044] Example 1:

[0045] like Figures 1 to 5 As shown, an automatic guide rod shearing machine is used to cut off the excess portion of the guide rod head of a heating tube. It includes a worktable 1, a mounting base 2, a guide rod locking device 3, a guide rod shearing device 4, and a guide rod clamping and conveying device 5. The mounting base 2 is located on the worktable 1 and has a cutting notch 21. The design of the cutting notch 21 provides specific space for the insertion and cutting of the guide rod head. Its shape and size can be rationally designed according to the specifications of the guide rod to ensure accurate insertion and stability during the cutting process. The guide rod locking device 3 is located on the mounting base 2 and is used to clamp the head of the guide rod inserted into the cutting notch 21. During the cutting operation, the guide rod locking device 3 firmly fixes the guide rod, preventing it from moving or shaking under the action of the moving blade 42. This ensures the precision of the cutting by the coordinated design of the moving blade 42 and the fixed blade 43, resulting in a smooth and flat guide rod head that meets quality requirements. A guide rod cutting device 4 is mounted on the mounting base 2. The guide rod cutting device 4 includes a pushing mechanism 41, a moving blade 42, and a fixed blade 43. One end of the fixed blade 43 extends into the cutting rod recess 21, providing a fixed cutting reference for the removal of the guide rod. The pushing mechanism 41 is connected to the mounting base 2 and to the moving blade 42, driving the moving blade 42 to move within the cutting rod recess 21 to cooperate with the fixed blade 43 in removing the excess portion of the guide rod head of the heating tube. When the guide rod is inserted into the cutting rod recess 21 and clamped by the guide rod locking device 3, the pushing mechanism 41 is activated, driving the moving blade 42 to move within the cutting rod recess 21, thereby cooperating with the fixed blade 43 to remove the excess portion of the guide rod head of the heating tube. A guide rod clamping and conveying device 5 is mounted on the worktable 1, used to clamp and convey the guide rod inserted into the cutting rod recess 21. The guide rod clamping and conveying device 5 can automatically complete the gripping, positioning, and conveying operations of the guide rod, improving production efficiency.

[0046] This automatic guide bar shearing machine combines a mounting base 2, a guide bar locking device 3, a guide bar shearing device 4, and a guide bar clamping and conveying device 5 set on the workbench 1. Through the coordinated operation of the guide bar clamping and conveying device 5, the guide bar locking device 3, and the guide bar shearing device 4, the automatic clamping, fixing, and cutting operations of the guide bar are realized. The machine has a high degree of automation, which greatly improves production efficiency, reduces manual intervention, and reduces labor intensity.

[0047] In this embodiment, the guide bar shearing device 4 includes not only a pushing mechanism 41, a moving blade 42, and a fixed blade 43, but also a fastening adjustment member 44, a locking adjustment member 45, and a guide bar limiting member 46; the other end of the fixed blade 43 is fixedly connected to the mounting base 2 via the fastening adjustment member 44; the moving blade 42 and the fixed blade 43 are located on the left and right sides of the cutting bar notch 21, respectively; the locking adjustment member 45 is mounted on the mounting base 2; the rear end of the guide bar limiting member 46 is connected to the locking adjustment member 45. Furthermore, the locking adjustment member 45 can be adjusted to move relative to the cutting rod recess 21 in the front-back direction; the front end of the guide rod limiting member 46 is placed inside the cutting rod recess 21; the front end of the guide rod limiting member 46 has a limiting slot 461 that opens in the front-back direction and is used to limit the entry of the guide rod head; the front end of the guide rod limiting member 46 also has a shearing opening 462 that opens downward and communicates with the limiting slot 461; one end of both the moving blade 42 and the fixed blade 43 is located inside the shearing opening 462. With this design of the guide rod shearing device 4, the position of the guide rod limiting member 46 can be precisely adjusted by the locking adjustment member 45 to ensure that the guide rod head accurately enters the limiting slot 461 and to limit the progress of the guide rod head entering the limiting slot 461; at the same time, it allows the moving blade 42 and the fixed blade 43 to achieve precise cutting within the shearing opening 462, reducing errors and improving cutting quality. Furthermore, the design of the fastening adjustment component 44 and the locking adjustment component 45 allows users to quickly adjust the position of the fixed blade 43 and the guide rod limit component 46 according to different heating tube specifications and cutting requirements, adapting to various production scenarios.

[0048] In this embodiment, the pushing mechanism 41 is specifically a linear pushing assembly 411; the moving blade 42 is located close to the rear side of the fixed blade 43; the linear pushing assembly 411 is a cylinder, electric cylinder, or hydraulic cylinder; of course, other types of linear pushing assemblies 411, such as motor-driven lead screw mechanisms, can also be used according to actual production needs. Different driving methods have different characteristics and applicable ranges, and can be selected according to actual production needs. The linear pushing assembly 411 drives the moving blade 42 to reciprocate in the left-right direction relative to the fixed blade 43, so as to cooperate with the fixed blade 43 to cut off the excess part of the guide rod end of the heating tube. The linear movement of the moving blade allows for precise control of the moving distance and speed of the moving blade 42, ensuring the cooperation accuracy between the moving blade 42 and the fixed blade 43, thereby achieving precise cutting off of the excess part of the guide rod end of the heating tube and reducing cutting errors. Moreover, the linear reciprocating motion of the moving blade 42 can quickly complete the cutting action without a complicated adjustment process, improving production efficiency. The linear drive assembly 411 has a fast response speed, which can adapt to the needs of different production cycles. In addition, the linear drive assembly 411 has a relatively simple structure, stable operation, and is not prone to jamming or malfunction. This design also makes the cooperation between the moving blade 42 and the fixed blade 43 more stable, which can ensure the consistency of cutting quality.

[0049] The fastening adjustment component 44 includes a fastening pressure plate 441 and a fastening bolt 442; the mounting base 2 has a fastening groove 22 on the right side of the guide rod recess that matches the other end of the fixed blade 43; the fastening pressure plate 441 presses the fixed blade 43 into contact with the mounting base 2; the fastening bolt 442 passes through the fastening pressure plate 441, the other end of the fixed blade 43, and connects to the mounting base 2. By combining the fastening plate 441 and the fastening bolt 442, and through the matching of the fastening groove 22 with the fixed blade 43, as well as the synergistic effect of the fastening plate 441 and the bolt, the position of the fixed blade 43 on the mounting base 2 can be accurately fixed, reducing shearing errors caused by positional deviations and improving the accuracy of the guide bar shearing. Furthermore, the fastening plate 441 presses the fixed blade 43 against the mounting base 2, while the fastening bolt 442 passes through all three to achieve connection. This dual fixing method enhances the connection stability between the fixed blade 43 and the mounting base 2, effectively withstanding the impact and vibration during the shearing process, preventing the fixed blade 43 from loosening or shifting, and ensuring the normal operation of the equipment. Moreover, the design of the fastening bolt 442 makes the position adjustment of the fixed blade 43 more convenient. When fine-tuning the position of the fixed blade 43 is required, simply loosen the fastening bolt 442, adjust the position of the fixed blade 43, and then retighten it. The operation is simple and quick, and can rapidly meet different processing needs.

[0050] The locking adjustment component 45 includes a fastening sleeve 451 and a locking bolt 452. The mounting base 2 has a placement groove 23 at its rear end corresponding to the position of the cutting rod recess 21. The rear end of the guide rod limiting component 46 is embedded in the placement groove 23 and is fitted onto the rear end of the guide rod limiting component 46 by the fastening sleeve 451. The fastening sleeve 451 and the mounting base 2 are connected by several locking bolts 452. Through the cooperation of the fastening sleeve 451 and the locking bolts 452, the position of the guide rod limiting component 46 can be precisely adjusted, ensuring its stability during operation and preventing positional displacement due to vibration or external force, thereby improving shearing accuracy and product quality. The clamp-type connection between the placement groove 23 and the fastening sleeve 451 makes the installation and removal of the guide rod limiting component 46 more convenient. When it is necessary to replace or repair the limiting component, simply loosening the locking bolts 452 allows for quick operation, reducing maintenance costs and downtime. This design of the locking adjustment component 45 allows for flexible adjustment of the tightness of the guide bar limiting component 46 by adjusting the tightness of the locking bolt 452, thus adapting to the shearing requirements of bars of different diameters or materials and improving the versatility and flexibility of the equipment.

[0051] In this embodiment, the guide rod locking device 3 includes a first pushing component 31, a second pushing component 32, a guide rod bracket 33, a fixed pressure block 34, and a dynamic pressure block 35. The first pushing component 31 and the second pushing component 32 are respectively connected to the mounting base 2. Preferably, the first pushing component 31 is a pneumatic cylinder or an electric cylinder, and the second pushing component 32 is a hydraulic cylinder. The guide rod bracket 33 is connected to the extended end of the first pushing component 31 and can move in and out at the front side of the cutting rod notch 21 by being driven by the first pushing component 31. The guide rod bracket 33 can move freely in and out at the front side of the cutting rod notch 21, and cooperates with the first pushing component 31 to quickly complete the support and placement of the guide rod, improve the stability of shearing, and help improve production efficiency. The mounting base 2 is provided with a first mounting groove 24 and a second mounting groove 25 that communicate with the cutting rod recess 21. The design of the first mounting groove 24 and the second mounting groove 25 makes the installation and movement of the fixed pressure block 34 and the moving pressure block 35 more regular, reduces interference between components, enhances the overall stability and reliability of the device, and reduces the failure rate. One end of the fixed pressure block 34 is installed in the first mounting groove 24, and the other end extends into the cutting rod recess 21. One end of the moving pressure block 35 is movably placed in the second mounting groove 25 and connected to the second pushing component 32, and the other end is aligned with the position of the fixed pressure block 34 and extends into the cutting rod recess 21. The second pushing component 32 drives the moving pressure block 35 to move toward the position of the fixed pressure block 34 so as to press the end of the guide rod against the fixed pressure block 34. By combining the first pushing component 31, the second pushing component 32, the guide rod bracket 33, the fixed pressure block 34, and the moving pressure block 35, the guide rod bracket 33 and the moving pressure block 35, through the synergistic action of the first pushing component 31 and the second pushing component 32, can precisely control the position of the guide rod head, ensuring stable fixation of the guide rod during the cutting process, avoiding a decrease in cutting accuracy due to shaking or displacement, and improving the quality of the finished product. Of course, in other embodiments, the guide rod locking device 3 can also adopt other structural forms, such as an electromagnetic locking structure, which uses electromagnetic force to lock and fix the head of the guide rod.

[0052] To enhance the stability of the guide rod placed on the guide rod bracket 33, the guide rod bracket 33 has an upward-facing support groove 331. When the first pushing assembly 31 drives the guide rod bracket 33 to the front side of the cutting rod recess 21, the support groove 331 provides more stable support, keeping the guide rod stable during operation and preventing positional displacement due to vibration or external forces, thereby improving shearing accuracy and product quality.

[0053] In this embodiment, the rod clamping and conveying device 5 includes a first moving module 51, a second moving module 52, a third moving module 53, a laser positioner 54, a pneumatic chuck mechanism 55, and a support bracket 56. The first moving module 51, the second moving module 52, and the third moving module 53 are respectively mounted on the workbench 1, the first moving module 51, and the second moving module 52. The pneumatic chuck mechanism 55 and the laser positioner 54 are both mounted on the third moving module 53 and can move relative to the mounting base 2 in the front-back, left-right, and up-down directions by the drive of the first moving module 51, the second moving module 52, and the third moving module 53. The support bracket 56 is positioned between the support bracket 56 and the pneumatic chuck mechanism 55, aligning with the rod cutting notch 21. The first moving module 51, the second moving module 52, and the third moving module 53 are respectively mounted on the workbench 1, the first moving module 51, and the second moving module 52, forming a three-stage linkage structure. This design gives the device three degrees of freedom in the front-back, left-right, and up-down directions, improving the flexibility of clamping and conveying the guide rod. With this design, the laser positioner 54, in conjunction with the pneumatic chuck mechanism 55, can achieve high-precision positioning and clamping of the guide rod. Through the coordinated drive of the three moving modules, the position can be flexibly adjusted to ensure that the guide rod is accurately aligned with the cutting notch 21 before shearing, reducing errors and improving shearing quality. Furthermore, the support bracket 56, aligned with the cutting notch 21 and located between the pneumatic chuck mechanism 55 and the support bracket 56, provides stable support and guidance for the guide rod. During conveying, it effectively prevents the guide rod from swaying or deviating, ensuring the continuity and stability of the shearing process, improving production efficiency. The automated control of the various moving modules and the pneumatic chuck mechanism 55 reduces manual operation, lowers labor intensity, and improves the level of automation and consistency in production, contributing to improved product quality and production efficiency. Of course, in other embodiments, such as the guide rod clamping and conveying device 5, a robotic arm structure can be used to grip the guide rod and accurately convey it into the cutting notch 21.

[0054] To provide more stable support and guidance for the guide rod, and to effectively prevent the guide rod from swaying or deviating during the conveying process, ensuring the continuity and stability of the shearing process and improving production efficiency, at least two of the aforementioned support brackets 56 are located between the support brackets 56 and the pneumatic chuck mechanism 55. In this embodiment, the number of support brackets 56 is two; however, the number of support brackets 56 is not limited to this and can be reasonably set according to requirements.

[0055] To better demonstrate the automation performance of the automatic guide rod shearing machine, it also includes a guide rod collecting frame 6 located on one side of the support bracket 56. After the excess portion of the guide rod head of the heating tube is removed, the position of the pneumatic chuck mechanism 55 is adjusted using the first moving module 51, the second moving module 52, and the third moving module 53, thereby clamping the guide rod, removing it from the support bracket 56, and placing it into the guide rod collecting frame 6.

[0056] The principle of this automatic guide bar shearing machine is as follows:

[0057] The guide rod for processing the heating tube is placed on the support bracket 56. The first moving module 51, the second moving module 52, and the third moving module 53 are driven in coordination, and the laser positioner 54 is used for positioning. The position of the pneumatic chuck mechanism 55 is flexibly adjusted to ensure that the guide rod is accurately aligned with the cutting notch 21 before shearing. At this time, the pneumatic chuck mechanism 55 locks the guide rod, so that the head end of the guide rod moves along the cutting notch 21 on the support bracket 56.

[0058] Next, when the head end of the guide rod approaches the front side of the cutting rod recess 21, the first pushing component 31 drives the guide rod bracket 33 to the front side of the cutting rod recess 21 to support the head end of the guide rod; at the same time, the head end of the guide rod continues to be inserted into the cutting rod recess 21 and enters the limiting slot 461 and the shearing slot 462, and the guide rod limiting member 46 restricts the insertion and movement of the head end of the guide rod.

[0059] Then, the second pushing component 32 drives the moving pressure block 35 to move toward the position of the fixed pressure block 34 so as to press the head end of the guide rod with the fixed pressure block 34, thereby accurately controlling the position of the head end of the guide rod and ensuring that the guide rod is stably fixed during the shearing process, avoiding it from shaking or deviating.

[0060] Finally, the moving blade 42 is driven by the pushing mechanism 41 to move toward the position of the fixed blade 43, and cooperates with the fixed blade 43 to remove the excess part of the guide rod head of the heating tube. After the shearing is completed, the pneumatic chuck mechanism 55 clamps the guide rod and resets it under the coordinated drive of the first moving module 51, the second moving module 52, and the third moving module 53. Then, the position of the pneumatic chuck mechanism 55 is adjusted by the first moving module 51, the second moving module 52, and the third moving module 53, so that the guide rod can be clamped and moved out of the support bracket 56 and placed in the guide rod collection frame 6 to complete the removal of the excess part of the guide rod head.

[0061] Example 2:

[0062] In this embodiment, as Figure 6As shown, the automatic rod shearing machine of Embodiment 2 is basically the same as that of Embodiment 1, except that the pushing mechanism 41 includes a linear pushing component 411, a positioning shaft 412, and a rotating swing component 413. The positioning shaft 412 is mounted on the mounting base 2, providing stable support and a rotation center for the rotating swing component 413, ensuring that the rotating swing component 413 will not wobble or deviate during operation, thus guaranteeing the stability of the entire pushing mechanism 41. The rotating swing component 413 is oscillatingly connected to the positioning shaft 412 and rotates around the central axis of the positioning shaft 412. The moving blade 42 is connected to the rotating swing component 413. The linear pushing component 411 is connected to the rotating swing component 413 and drives the moving blade 42 to rotate synchronously with the rotating swing component 413, and rotates closer to the fixed blade 43 to cooperate with the fixed blade 43 to cut off the excess part of the rod tip of the heating tube. In Embodiment 2, the pushing mechanism, based on the linear pushing assembly 411, adds a positioning shaft 412 and a rotating oscillating component 413. The linear pushing assembly 411 drives the rotating oscillating component 413 to rotate around the central axis of the positioning shaft 412, thereby driving the moving blade 42 to rotate. This causes the moving blade 42 to rotate closer to the fixed blade 43, cooperating with the fixed blade 43 to remove the excess portion from the tip of the heating tube's guide rod. This design, through the coordinated action of the linear pushing assembly 411, the positioning shaft 412, and the rotating oscillating component 413, allows the moving blade 42 to precisely rotate and approach the fixed blade 43, achieving accurate removal of the excess portion from the tip of the heating tube's guide rod, ensuring consistent and accurate removal results. Simultaneously, the linear pushing assembly 411 directly drives the rotating oscillating component 412, reducing intermediate transmission links and improving power transmission efficiency. This allows the moving blade 42 to quickly complete its rotation and approach to the fixed blade 43, thereby improving production efficiency.

[0063] In summary, the embodiments of the present invention provide an automatic guide rod shearing machine, wherein the automatic guide rod shearing machine has the following advantages:

[0064] 1. By combining the mounting base 2, the guide rod locking device 3, the guide rod shearing device 4, and the guide rod clamping and conveying device 5 on the workbench 1, the automatic clamping, fixing, and cutting operations of the guide rod are realized through the coordinated operation of the guide rod clamping and conveying device 5, the guide rod locking device 3, and the guide rod shearing device 4. The automation level is high, which greatly improves production efficiency, reduces manual intervention, and reduces labor intensity.

[0065] Second, the guide rod locking device 3 can firmly fix the guide rod and prevent it from moving during the cutting process.
