Description

Technical Field

[0001] The present invention relates to the technical field of valve scoring, and particularly to a scoring device for valve processing. Background Technique

[0002] In valve processing, scoring is an important process step, which is used to improve the sealing performance of the valve, reduce friction, and extend the service life. Scoring is usually achieved through specific process equipment, such as engraving knives or laser scoring machines.

[0003] For example, the "scoring device for valve processing" with the publication number of CN111347106B includes a scoring mechanism, a clamping mechanism, a workbench, a rotating mechanism, and a dust removal mechanism. The scoring mechanism includes a lifting table, a lifting component, an angle adjustment component, and a tool mounting component. The dust removal mechanism includes a chip blowing component, a spraying component, and a chip collecting component. The chip blowing component and the spraying component are respectively arranged on both sides of the clamping mechanism.

[0004] However, in the prior art, when scoring a valve, a large amount of burrs and flash will be generated at the scoring position. These burrs and flash need to be processed later, and there is a long time interval between them and the scoring, which will cause the entire processing process to take more time. Moreover, during the scoring process, the presence of burrs and flash is likely to interfere with the operator's line of sight, resulting in the operator being unable to clearly see the specific situation inside the score, and it is easy to have problems such as the score being too deep or too shallow and uneven scoring, which will directly affect the scoring effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a scoring device for valve processing to solve the problem that burrs and flash in the above background technique are likely to interfere with the operator's line of sight, resulting in the operator being unable to clearly see the specific situation inside the score.

The first positioning head is fixedly installed at the other end of the rotating rod. One end of the transmission belt is movably connected to the outer wall of the first positioning head. The top of the grinding block is fixedly connected with a second positioning head, which is movably connected to the other end of the transmission belt. The second positioning head is rotatably installed at the bottom of the positioning tube, and the positioning tube is sleeved on the outer wall of the tool bar of the engraving knife.

[0009] Preferably, a receiving shell is arranged outside the toothed plate. A cavity is opened inside the receiving shell. The toothed plate is located inside the cavity, above the driven gear, and the tool bar of the engraving knife penetrates through the receiving shell.

[0010] Preferably, an adapter block is threadedly connected to the outer wall of the mounting connecting plate, and the top of the receiving shell is fixedly connected to the bottom of the adapter block.

[0014] Preferably, a protection frame is fixedly connected to the outer wall of the stepping motor. One side of the protection frame is fixedly connected with a slider, and one side of the slider is slidably connected with a guide rail.

[0015] Preferably, both ends of the guide rail are fixedly connected with support plates. A docking plate is fixedly connected between the two support plates, and the docking plate is fixedly connected to one end of the auxiliary force arm.

[0016] Preferably, a servo motor is fixedly installed at one end of one of the support plates. The output end of the servo motor is fixedly connected with a transmission rod, and one end of the transmission rod is fixedly connected with a lead screw.

[0017] Preferably, the lead screw is threadedly connected to the protection frame, and both ends of the lead screw are respectively rotatably installed inside the two support plates.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, a polishing assembly is provided on the outer wall of the engraving tool. When making a notch on the valve, the polishing block in the polishing assembly can be driven by the engraving tool, so that during the notching process, the edge of the notched part can be polished. The polishing block surrounds the engraving tool, and can quickly remove the burrs and rough edges at the edge of the valve notch. Removing the rough edges allows the operator to accurately see the specific situation of the notch, so as to adjust the engraving method according to the engraving quality, thus avoiding problems such as too deep or too shallow notches and uneven notches. Moreover, notching and polishing the rough edges are carried out simultaneously, which can save the subsequent process of processing the rough edges, play a role in improving the processing efficiency, and there is also a certain space reserved between the positioning tube and the engraving tool, so that the polishing assembly will not affect the normal progress of notching.

[0020] 2. In the present invention, when the connecting block is sleeved on the installation connecting plate, the toothed plate will be stuck with the tool shank of the engraving tool, and then rotating the connecting block can install the polishing assembly on the installation connecting plate. The overall installation and disassembly are of low difficulty, so the installation and disassembly operations can be carried out at any time. Moreover, the angular velocity of the toothed plate is equal to the angular velocity of the engraving tool, and the radius of the driven gear is smaller than the radius of the toothed plate, which enables the rotational speed of the rotating rod to be significantly increased during the transmission process. By increasing the rotational speed of the rotating rod, the efficiency and quality of the polishing work can be effectively improved. In addition, the polishing block completely covers the edge of the positioning tube, ensuring that the polishing area can completely cover the notch and its surrounding area. This design can ensure that the entire notch area is fully covered during the polishing operation, so as to obtain a more uniform and high-quality polishing effect.

[0021] 3. In the present invention, the stepping motor is installed on the protection frame, which can not only ensure the structural stability of the stepping motor itself, but also contribute to the stability and reliability of the entire device. The protection frame is slidably connected to the guide rail through the slider. This connection method enables the protection frame to move precisely along the path set by the guide rail. During operation, the servo motor drives the lead screw to change the position of the protection frame, and then adjusts the position of the engraving tool. At the same time, in combination with the use of the main arm and the auxiliary arm, precise engraving of notches with different shapes and sizes can be achieved. This design can meet different engraving requirements and improve the accuracy and efficiency of the engraving operation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8Shown: A notching device for valve processing, including a device base 1. A main arm 2 is rotatably connected to the top of the device base 1. One end of the main arm 2 is rotatably connected to a sub-arm 3. One end of the sub-arm 3 is rotatably connected to a notching assembly 4. The notching assembly 4 is used for notching on the valve. A grinding assembly 5 is arranged on the outer wall of the notching assembly 4;

[0034] The notching assembly 4 includes a stepping motor 46 and a carving knife 47. One end of the carving knife 47 is fixedly connected to a mounting connecting plate 411. The mounting connecting plate 411 is fixedly installed on the outer wall of the stepping motor 46 through bolts. The output end of the stepping motor 46 is movably connected to the carving knife 47 through an expansion sleeve;

[0035] The grinding assembly 5 includes a toothed plate 58, a rotating rod 59, a first positioning head 53, a transmission belt 55, a positioning tube 52 and a grinding block 56. The toothed plate 58 is clamped and connected to the tool rod of the carving knife 47. One end of the rotating rod 59 is fixedly installed with a driven gear 511. The driven gear 511 is meshed and connected with the toothed plate 58. The first positioning head 53 is fixedly installed at the other end of the rotating rod 59. One end of the transmission belt 55 is movably connected to the outer wall of the first positioning head 53. The top of the grinding block 56 is fixedly connected to a second positioning head 514. The second positioning head 514 is movably connected to the other end of the transmission belt 55. The second positioning head 514 is rotatably installed at the bottom of the positioning tube 52. The positioning tube 52 is sleeved on the outer wall of the tool rod of the carving knife 47.

[0036] In this embodiment, the main arm 2 plays a key role in controlling the position of the sub-arm 3 in this working process. The sub-arm 3 is responsible for controlling the direction and angle of the notching assembly 4, so as to accurately send the notching assembly 4 near the valve for processing. When processing the valve, the sub-arm 3 will accurately position the notching assembly 4 to the correct position, paving the way for the subsequent notching operation. Subsequently, the stepping motor 46 is activated to quickly drive the carving knife 47 to start rotating at a high speed. The cutting head of the carving knife 47 contacts the surface of the valve. The force of the high-speed rotation can be used to cut precise traces on the surface of the valve. This process requires highly precise control and coordination to ensure that the depth, shape and position of the notch meet the design requirements;

[0037] During the operation of the notching assembly 4, the grinding assembly 5 arranged on the carving knife 47 will be driven synchronously. The carving knife 47 is installed on the stepping motor 46 through the mounting connecting plate 411. One end of its tool rod is connected to the output end of the stepping motor 46 through an expansion sleeve. At the same time, the tool rod is also clamped and connected to the toothed plate 58 together, ensuring the stability and reliability of the tool during operation. Using the carving knife 47 as the power source for driving the operation of the grinding assembly 5, the carving and grinding are carried out synchronously. The carving knife 47 is located in the positioning tube 52 and will not have a negative impact on the notching effect, ensuring the notching quality and accuracy;

[0038] During the rotation of the tool shank, the toothed plate 58 will be driven synchronously. The driven gear 511 is arranged at the bottom of the toothed plate 58. The toothed plate 58 then drives the rotating rod 59 through the driven gear 511. During the rotation of the rotating rod 59, the second positioning head 514 is driven by the transmission belt 55 arranged on the first positioning head 53, so as to achieve the purpose of driving the grinding block 56 to rotate at a high speed. The second positioning head 514 is installed at the bottom of the positioning tube 52. Through the connection with the transmission belt 55, it can effectively receive the power transmitted from the rotating rod 59 and transmit the power to the grinding block 56;

[0039] During the entire notching process, the stepper motor 46 drives the engraving tool 47 to rotate at a high speed, and uses the tool tip to make marks on the surface of the valve. At the same time, the rotation of the engraving tool 47 will also drive the grinding block 56 installed under the positioning tube 52 synchronously. The burrs and rough edges on the valve are removed by the grinding block 56, so that the entire notching path remains clean and tidy. This design utilizes the characteristics of simultaneous driving. The movement of the grinding block 56 is driven by the rotation of the engraving tool 47, ensuring that the trace path is cleaned and leveled while notching. Such an operation can facilitate the operator to check the shape and specifications of the marks and adjust the notching method at any time, thus ensuring the accuracy and operability of the notching process;

[0040] Since the angular velocity of the toothed plate 58 is equal to that of the engraving tool 47, and the radius of the driven gear 511 is smaller than that of the toothed plate 58, according to the transmission principle, the angular velocity of the driven gear 511 will be much greater than that of the toothed plate 58 during the transmission process. This design can achieve speed increase through the change of the transmission ratio, and the rotation speed of the rotating rod 59 has been greatly increased, thus effectively ensuring the quality and efficiency of grinding.

[0041] Embodiment 2

[0042] According to Figure 5 、 Figure 6 and Figure 7As shown in the figure, a receiving shell 51 is provided outside the toothed plate 58. A cavity 512 is formed inside the receiving shell 51. The toothed plate 58 is located inside the cavity 512 and above the driven gear 511. The shank of the engraving tool 47 penetrates through the receiving shell 51. An adapter block 412 is threadedly connected to the outer wall of the mounting connection plate 411. The top of the receiving shell 51 is fixedly connected to the bottom of the adapter block 412. Positioning holes 513 are formed at the edge of the receiving shell 51. The rotating rod 59 is located inside the positioning holes 513. A limiting plate 510 is fixedly installed on the outer wall of the rotating rod 59. The limiting plate 510 is located inside the cavity 512. Positioning grooves 516 are formed at the edge of the bottom of the positioning tube 52. The second positioning head 514 is located inside the positioning grooves 516. A positioning plate 515 is fixedly installed at the junction of the second positioning head 514 and the transmission belt 55. A limiting block 54 is fixedly installed at the junction of the first positioning head 53 and the rotating rod 59. The limiting block 54 is located on the outer wall of the receiving shell 51. The top of the positioning tube 52 is fixedly connected to a closing cover plate 57. The closing cover plate 57 is welded to the bottom of the receiving shell 51.

[0043] In this embodiment, the toothed plate 58 and the driven gear 511 are arranged in the cavity 512 inside the receiving shell 51. This design effectively isolates them and protects them from external interference and influence, ensuring that the grinding assembly 5 can always operate properly. The rotating rod 59 is arranged in the positioning holes 513, and a limiting plate 510 and a limiting block 54 are also arranged on its outer wall. These components play a role in limiting the position of the rotating rod 59, ensuring that the position of the driven gear 511 is always correctly meshed with the toothed plate 58, avoiding problems such as structural looseness or instability during operation. Through the arrangement of the limiting plate 510 and the limiting block 54, the positions of the components in the system are accurately positioned, thus ensuring the stability and reliability of the equipment, enabling the grinding assembly 5 to maintain efficient and stable operation during long-term work, and ensuring the processing quality and equipment life.

[0044] The receiving shell 51 and the adapter block 412 are firmly connected together through a connection method, ensuring the stability of the overall structure. The adapter block 412 is threadedly connected to the bottom of the mounting connection plate 411. This connection method is simple and effective, facilitating maintenance and component replacement. When installing the grinding assembly 5, first, the positioning tube 52 is sleeved outside the engraving tool 47, which can ensure that the guide rod of the engraving tool 47 is correctly engaged with the toothed plate 58, thus ensuring the accuracy and efficiency of the grinding process. Subsequently, the adapter block 412 is installed on the mounting connection plate 411 to complete the connection between the grinding assembly 5 and the scoring assembly 4. The entire operation process is simple and easy to perform, with a low operation difficulty, facilitating users to install and replace components.

[0045] The top closed cover plate 57 of the positioning tube 52 is welded to the bottom of the accommodating shell 51, ensuring that the internal space of the accommodating shell 51 remains closed. This design can effectively prevent external impurities and dust from entering the inside of the accommodating shell 51, protect the internal components of the device from contamination, improve the service life and stability of the device. The transmission belt 55 is arranged outside the accommodating shell 51. This design facilitates the replacement and maintenance of the transmission belt 55. Users can easily access the transmission belt 55 to achieve quick replacement, reduce the maintenance time and repair costs, and improve the reliability and usage efficiency of the device. The second positioning head 514 is located in the positioning groove 516 at the bottom of the positioning tube 52 and is integrally surrounded at the edge of the positioning tube 52. This design enables the grinding assembly 5 to completely cover the grinding area of the scratch and its surrounding area. Through the precise positioning and surrounding design of the second positioning head 514, the accuracy and efficiency during the grinding process can be ensured, and the processing quality is improved.

[0046] Embodiment 3

[0047] According to Figure 2 、 Figure 3 and Figure 4 As shown, a protection frame 45 is fixedly connected to the outer wall of the stepper motor 46. One side of the protection frame 45 is fixedly connected with a slider 410. One side of the slider 410 is slidably connected with a guide rail 48. Both ends of the guide rail 48 are fixedly connected with support plates 42. A docking plate 41 is fixedly connected between the two support plates 42. A fixed connection is made between the docking plate 41 and one end of the secondary force arm 3. A servo motor 43 is fixedly installed at one end of one of the support plates 42. The output end of the servo motor 43 is fixedly connected with a transmission rod 49. One end of the transmission rod 49 is fixedly connected with a lead screw 44. The lead screw 44 is threadedly connected with the protection frame 45. Both ends of the lead screw 44 are respectively rotatably installed inside the two support plates 42.

[0048] In this embodiment, the stepper motor 46 is installed inside the protection frame 45. The protection frame 45 is connected to the guide rail 48 through the slider 410. When making a scratch, the servo motor 43 drives the lead screw 44 through the transmission rod 49, causing the protection frame 45 to move along the set path of the guide rail 48, thereby achieving precise adjustment of the position of the engraving tool 47. This design can not only improve the accuracy of the engraving operation, but also ensure the processing quality and efficiency.

[0049] Both ends of the lead screw 44 are installed on the support plates 42. This installation method ensures the structural stability of the lead screw 44 itself, enabling it to withstand the pressure and force during operation. At the same time, both ends of the guide rail 48 are connected to the junction of the support plates 42 and the docking plate 41. This structural design helps to improve the strength and stability of the overall device. The combination between the support plates 42 and the docking plate 41 makes the device more stable and reliable during operation, thus ensuring the smooth progress of the scratching work.

[0050] Usage method and working principle of this device: When processing a valve, install the grinding assembly 5 onto the scoring assembly 4. During installation, first slip the positioning tube 52 over the outside of the engraving tool 47 so that the guide rod of the engraving tool 47 engages with the toothed plate 58. Then, install the connecting block 412 onto the mounting connecting plate 411 to complete the connection between the grinding assembly 5 and the scoring assembly 4. During the processing, the secondary force arm 3 moves the scoring assembly 4 near the valve. Subsequently, the stepper motor 46 drives the engraving tool 47 to rotate at high speed, and the tip of the engraving tool 47 is used to score marks on the surface of the valve;

[0051] The high-speed rotation of the engraving tool 47 will synchronously drive the toothed plate 58 through the tool shank. The toothed plate 58 then drives the rotating rod 59 through the driven gear 511, and drives the second positioning head 514 through the transmission belt 55 provided on the first positioning head 53, achieving the purpose of driving the grinding block 56 to rotate at high speed. The grinding block 56 is used to remove the burrs and rough edges on the valve, keeping the entire scoring path clean and tidy, facilitating the operator to view the shape and specifications of the marks, and thus adjusting the scoring method at any time;

[0052] The servo motor 43 drives the lead screw 44 through the transmission rod 49, causing the protection frame 45 to move along the set path of the guide rail 48, thereby achieving precise adjustment of the position of the engraving tool 47. The second positioning head 514 is located in the positioning groove 516 at the bottom of the positioning tube 52 and surrounds the edge of the positioning tube 52 as a whole, enabling the grinding area to completely cover the scored area and its surrounding regions.
