Description

During the production process of the wire thread insert installation tool, it is usually necessary to use grinding equipment to grind the end of the wire thread insert installation tool. Currently, when grinding the wire thread insert installation tool, the wire thread insert installation tool is generally installed on the base of the grinding equipment at a certain inclination angle to ensure that the tool is firmly fixed and will not shift during the grinding process. Then, the motor arranged on the base of the grinding equipment drives the grinding wheel to rotate at high speed to evenly grind the end of the wire thread insert installation tool.

[0003] However, there are some problems in the grinding of the wire screw insert installation tool: during the grinding process, a large amount of heat will be generated in the area where the wire screw insert installation tool is in direct contact with the grinding wheel. The generated heat will cause the wire screw insert installation tool to thermally expand, thereby causing the area where the wire screw insert installation tool is ground to deform. At this time, when the grinding wheel is running at high speed, the area where the wire screw insert installation tool is ground will deform, which will change the overall geometric shape of the wire screw insert installation tool, resulting in uneven mass distribution of the wire screw insert installation tool, thereby causing dynamic imbalance between the grinding wheel and the wire screw insert installation tool, causing vibration between the grinding wheel and the wire screw insert installation tool.

DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1-5 The present embodiment provides a grinding device for a wire screw insert installation tool 5, comprising a base 1, a grinding assembly 2, a limiting assembly 3 and a supporting assembly 4. The grinding assembly 2, the limiting assembly 3 and the supporting assembly 4 are all arranged on the base 1. The head of the wire screw insert installation tool 5 passes through the limiting assembly 3 and fits with the grinding assembly 2. The supporting assembly 4 is sleeved on the wire screw insert installation tool 5, and the center of the supporting assembly 4 coincides with the center of mass of the wire screw insert installation tool 5, so that the grinding wheel 23 and the wire screw insert installation tool 5 maintain dynamic balance, such as Figure 1 As shown, firstly, since the wire screw sleeve installation tool 5 is large at one end and small at the other end and has a regular shape, the position of the center of mass can be determined. During the grinding process, if the grinding area of ​​the tool is deformed, this will change the geometric shape of the tool, resulting in uneven mass distribution, thereby causing dynamic imbalance. Therefore, a support is provided at the center of mass to keep the center of mass position of the tool stable, reduce the force generated by the center of mass offset, and thus reduce vibration. In addition, when the support component 4 is provided at the center of mass, it can disperse and absorb vibration energy. In this way, the vibration energy is absorbed by the support part, reducing the vibration transmitted to the entire tool and grinding equipment, and weakening the dynamic imbalance;

[0028] It should be noted that the grinding assembly 2 mentioned above includes a motor 21, a shaft connector 22 installed at the output end of the motor 21, and a grinding wheel 23 sleeved on the shaft connector 22. The grinding wheel 23 is a diamond grinding sheet. The motor 21 drives the shaft connector 22 to move, and the shaft connector 22 drives the grinding wheel 23 to grind the head of the wire screw sleeve installation tool 5. The limit assembly 3 includes a right-angle fixing seat 31 arranged on the base 1 and a guide positioning threaded plate 32 arranged on the right-angle fixing seat 31. The wire screw sleeve installation tool 5 is provided with a plurality of guides and positioning screw plates. The installation tool 5 penetrates the guide positioning thread plate 32, and the wire screw sleeve installation tool 5 is screwed to the guide positioning thread plate 32. The guide positioning thread plate 32 is provided with a plurality of screw holes that can adapt to different wire screw sleeve installation tools 5. In addition, the diamond grinding disc is fixed to the shaft connector 22 by fastening screws and compression washers. The motor 21 is installed on the base 1 through a dedicated motor 21 base 1. A speed regulator is also provided at the tail end of the motor 21. There is a speed regulating button on the speed regulator. The speed of the motor 21 is controlled by adjusting the speed regulator, such as Figure 2 As shown in the figure, in addition to the above-mentioned components, there is also an external control system to better control the grinding process.

[0029] At present, during the grinding process of the wire screw insert installation tool 5, a large amount of heat will be generated in the area where the wire screw insert installation tool 5 is in direct contact with the grinding wheel 23. The generated heat will cause the wire screw insert installation tool 5 to undergo thermal expansion, thereby causing the area where the wire screw insert installation tool 5 is ground to undergo deformation. At this time, under the condition that the grinding wheel 23 is running at a high speed, the area where the wire screw insert installation tool 5 is ground will undergo deformation, which will change the overall geometric shape of the wire screw insert installation tool 5, resulting in uneven mass distribution of the wire screw insert installation tool 5, thereby causing dynamic imbalance between the grinding wheel 23 and the wire screw insert installation tool 5, causing vibration between the grinding wheel 23 and the wire screw insert installation tool 5. In addition, under the condition that the grinding wheel 23 itself is running at a high speed, the vibration between the grinding wheel 23 and the wire screw insert installation tool 5 will be amplified, ultimately affecting the accuracy of the end of the wire screw insert installation tool 5.

[0030] In order to solve the above problems, in this embodiment, the grinding component 2, the limiting component 3 and the supporting component 4 are all arranged on the base 1, the head of the wire screw sleeve installation tool 5 passes through the limiting component 3 and fits with the grinding component 2, the supporting component 4 is sleeved on the wire screw sleeve installation tool 5, and the center of the supporting component 4 coincides with the center of mass of the wire screw sleeve installation tool 5, so that the supporting component 4 is arranged at the center of mass to disperse and absorb the vibration energy, so that the vibration energy is absorbed by the supporting part, thereby reducing the vibration transmitted to the entire tool and grinding equipment, and also reducing the force generated by the center of mass offset, thereby reducing vibration and weakening dynamic imbalance, solving the problem that the heat generated in the area where the wire screw sleeve installation tool 5 is in direct contact with the grinding wheel 23 in the prior art causes the wire screw sleeve installation tool 5 to undergo thermal expansion, and when the grinding wheel 23 runs at high speed, dynamic imbalance will occur between the grinding wheel 23 and the wire screw sleeve installation tool 5, causing vibration between the grinding wheel 23 and the wire screw sleeve installation tool 5.

[0031] In order to reduce the vibration of the grinding wheel 23 during the grinding process and avoid dynamic imbalance between the grinding wheel 23 and the wire screw insert installation tool 5 when the grinding wheel 23 runs at high speed, a support assembly 4 is set at the center of mass of the wire screw insert installation tool 5. However, when the wire screw insert installation tool 5 vibrates, the wire screw insert installation tool 5 and the support assembly 4 directly confront each other, which will also affect the dynamic balance between the grinding wheel 23 and the wire screw insert installation tool 5. In order to solve this problem, the support assembly 4 includes two support frames 41, and the two support frames 41 are symmetrically arranged on the base 1 on both sides of the axis at the center of mass of the wire screw insert installation tool 5. The two support frames 41 are connected as a whole, and the connection between the two support frames 41 forms an incomplete circular ring. The incomplete circular ring here is as shown in FIG. Figure 4 As shown in , the purpose of using an incomplete ring is to ensure that the support component 4 can provide support for the center of mass of the wire thread insert installation tool 5, and to ensure that the wire thread insert installation tool 5 can be easily removed after grinding. The annular structure of the wire thread insert installation tool 5 cooperates with the incomplete ring formed at the connection of the two support frames 41. The purpose here is to ensure that the movement trend of the support component 4 is parallel to the axis of the wire thread insert installation tool 5, which can more effectively absorb or offset the vibration caused by imbalance, because parallel movement helps to directly counteract the force generated by the unbalanced mass.

[0032] It is worth mentioning that, since it is a grinding process and the wire screw insert installation tool 5 is ground evenly, the mass of the wire screw insert installation tool 5 will become smaller during grinding. When the head of the wire screw insert installation tool 5 begins to be ground and the grinding is carried out evenly, the center of mass will gradually move toward the tail of the wire screw insert installation tool 5 as the material is removed. This is because the center of mass is determined by the mass distribution of each part of the object. When the mass of the thin end decreases, the center of mass will move to the part with larger mass. However, the movement process of the center of mass is weak. When the center of mass position moves and the support assembly 4 does not move, it will cause the support assembly 4 to move. The support position deviates from the center of mass. At this time, it is impossible to ensure that the grinding wheel 23 and the wire screw insert installation tool 5 are in continuous dynamic balance. In order to solve this problem, in one embodiment, a truncated cone limiting sleeve 6 is sleeved on the annular structure of the wire screw insert installation tool 5. The truncated cone limiting sleeve 6 and the wire screw insert installation tool 5 are friction limited, and it is necessary to ensure that after the truncated cone limiting sleeve 6 is subjected to external force, the truncated cone limiting sleeve 6 can move, the axis of the truncated cone limiting sleeve 6 coincides with the axis of the wire screw insert installation tool 5, and the bottom surface and top surface of the truncated cone limiting sleeve 6 are respectively located at one end close to the head of the wire screw insert installation tool 5 and close to the wire. At one end of the tail of the screw sleeve installation tool 5, the inner wall of the incomplete circular ring and the outer wall of the truncated cone limiting sleeve 6 are frictionally limited, and the incomplete circular ring can slide along the truncated cone limiting sleeve 6. A fixing block 7 is arranged on the base 1 near the truncated cone limiting sleeve 6. The fixing block 7 is connected to the side wall of the incomplete circular ring by a thermal expansion spring 8. The thermal expansion spring 8 drives the incomplete circular ring to slide along the truncated cone limiting sleeve 6. The thermal expansion spring 8 here needs to be taken into consideration in combination with the heat condition of the wire screw sleeve installation tool 5 during grinding, as well as the size of the wire screw sleeve installation tool 5 and the speed of the change of the center of mass of the wire screw sleeve installation tool 5, and the thermal expansion spring 8 is preferably used for the screw sleeve installation tool 5. The thrust provided by the spring 8 itself is not large, and here it just weakly cooperates with the actual movement process of the center of mass. In addition, the movement of the center of mass position must be accompanied by grinding heat, so that when the center of mass position moves, the support assembly 4 also moves accordingly, ensuring that the center of mass position and the support point of the support assembly 4 remain relatively still, ensuring that the grinding wheel 23 and the wire screw sleeve installation tool 5 are continuously in dynamic balance, and a slide groove that cooperates with the conical limit sleeve 6 is also required on the support frame 41 at the connection between the support frame 41 and the conical limit sleeve 6, so as to ensure that there is no interference between the support frame 41 and the conical limit sleeve 6 when it moves.

[0033] In addition, another point that needs to be considered is that, due to the use of the thermal expansion spring 8, based on the characteristics of the spring itself, when the thermal expansion spring 8 pushes the support component 4 to move toward the tail of the wire screw insert installation tool 5, the temperature cannot be guaranteed to be evenly distributed, which will cause different parts of the spring to expand to different degrees, thereby producing slight deformation and reciprocating motion. At this time, the thermal expansion spring 8 will drive the support component 4 to produce a slight reciprocating motion, which will affect the accuracy of the support component 4 corresponding to the center of mass position. Therefore, a truncated cone limit sleeve 6 is provided on the annular structure of the wire screw insert installation tool 5, such as Figure 3 As shown, the design of the truncated cone limit sleeve 6 can ensure that the support component 4 can only move toward the tail along the wire screw insert installation tool 5 and will not move toward the head of the wire screw insert installation tool 5, thereby overcoming the problem that the thermal expansion spring 8 will drive the support component 4 to produce a small reciprocating motion, which will affect the accuracy of the support component 4 corresponding to the center of mass position. This design is compatible with the movement of the center of mass of the wire screw insert installation tool 5.

[0034] Furthermore, in order to make the support assembly 4 move more smoothly, in one embodiment, there are two fixed blocks 7, and the two fixed blocks 7 are symmetrically arranged on the base 1 on both sides of the conical limiting sleeve 6. The two fixed blocks 7 are symmetrically arranged on the base 1 on both sides of the conical limiting sleeve 6, which can ensure balanced force in all directions, reduce the tilt or vibration caused by asymmetry, and thus improve the overall stability. The two fixed blocks 7 can share the weight of the support assembly 4 and the force generated during movement, reduce the pressure on a single fixed block 7, and reduce the risk of damage due to local overload.

[0035] Since the wire screw insert installation tool 5 needs to be fixed during grinding, the wire screw insert installation tool 5 needs to be removed after grinding. In order to make the wire screw insert installation tool 5 lighter and easier to operate, while ensuring the performance and stability of the tool under high temperature and wear conditions, and facilitating the adjustment and disassembly of the tool, in one embodiment, the truncated cone limiting sleeve 6 is made of carbon fiber material, which can not only withstand the high temperature during grinding, but also has a light weight, so as to avoid the truncated cone limiting sleeve 6 being set on the wire screw insert installation tool 5. The weight is too heavy, so that the wire screw sleeve installation tool 5 bears too much force. The truncated cone limiting sleeve 6 and the wire screw sleeve installation tool 5 are connected as a whole through a fixed ring 9 with an adjustable size. The fixed ring 9 includes an arcuate inner ring 91 and an arcuate outer ring 92. The inner wall of the arcuate inner ring 91 fits with the outer surface of the wire screw sleeve installation tool 5, and the outer wall of the arcuate outer ring 92 fits with the inner wall of the truncated cone limiting sleeve 6. The outer wall of the arcuate inner ring 91 and the inner wall of the arcuate outer ring 92 are connected by a gear 93 rack 94 telescopic structure, such as Figure 5As shown, two arcuate inner rings 91 and arcuate outer rings 92 are provided, and are symmetrically arranged. The arcuate inner ring 91 and the arcuate outer ring 92 are both incomplete rings. This design is to ensure that the truncated cone-shaped limiting sleeve 6 and the wire screw sleeve installation tool 5 can be pressed and fitted together by the arcuate inner ring 91 and the arcuate outer ring 92, and it can also ensure that the wire screw sleeve installation tool 5 is easy to detach from the fixing ring 9 after grinding, so that the wire screw sleeve installation tool 5 can be easily removed. The gear 93 rack 94 telescopic structure includes a gear 93 and two racks 94. The two racks 94 are connected by a connecting block, and the rack 94 slides through the connecting block, such as Figure 5 As shown in the figure, an adjusting screw 95 is vertically arranged at the axis of the gear 93, and the adjusting screw 95 is connected to the base 1 through a support rod. The adjusting screw 95 is fixedly connected to the axis of the gear 93, and two racks 94 are meshingly arranged on both sides of the gear 93. The adjusting screw 95 drives the gear 93 to rotate, and the gear 93 drives the two racks 94 to move. In fact, the adjusting screw 95 and the support rod are threaded to ensure that the arc-shaped inner ring 91 and the arc-shaped outer ring 92 are limited after moving to the appropriate position.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
