Description

Technical Field

[0001] This utility model relates to the field of machine tool fixture technology, specifically to a rotary fixture for CNC equipment with dispensing nozzles. Background Technology

[0002] The dispensing nozzle is a key component in dispensing equipment, used to precisely control the distribution of fluids such as adhesives. During the production process, the dispensing nozzle needs to be milled by CNC equipment to make the end face of the dispensing nozzle have an annular groove. CNC equipment is a technology that uses computer programs to control machine tools or other processing equipment for automated processing. CNC equipment controls the movement of machine tools and processing by reading pre-written numerical control programs. Traditional CNC equipment uses three sets of imported ball end mills for high-speed CNC milling and adopts three-dimensional milling.

[0003] A CNC machine fixture is a workpiece fixing device used in CNC milling to ensure the stability of the raw material during the milling process, ensure that the workpiece is in the correct position on the milling machine relative to the cutting tool and machine tool coordinate axes, and ensure the machining dimensional accuracy and geometric tolerances.

[0004] While existing fixtures offer numerous advantages, they still suffer from several drawbacks: insufficient precision in nozzle machining, high equipment costs due to the use of 3D milling, high demands on equipment due to high-speed 3D milling, and more pronounced quadrant issues as the path narrows, resulting in a high defect rate for the machined nozzles. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a special rotary fixture for CNC equipment for dispensing nozzles.

[0006] The technical solution adopted by this utility model to solve its technical problem is a special rotary fixture for CNC equipment for dispensing nozzles, including a fixed platform, a fixed base, and a support base. A processing table is provided on the upper outer wall of the fixed platform. Fixed bases are installed on both sides of the upper outer wall of the processing platform. A screw is threadedly connected inside the fixed base. A first clamping block is provided on one side of the outer wall of the screw. A fitting groove is symmetrically opened on both sides of the outer wall of the first clamping block. A combination groove is opened on both sides of the outer wall of the upper outer wall of the first clamping block. Support bases are installed on both sides of the upper outer wall of the processing platform. A stud is movably installed inside the support base. An assembly plate is installed on one side of the outer wall of the stud.

[0007] By adopting the above technical solution, the combination of the fixing seat and the screw allows the position of the first clamping block to be adjusted by rotating the screw, thus enabling flexible clamping according to the size and shape of the dispensing nozzle. By adjusting the usage position of the two first clamping blocks, the position of the nozzle can be adjusted to ensure that the nozzle is aligned with the axis of the processing table. The clamping of the nozzle by the two first clamping blocks ensures the lateral clamping and fixing of the nozzle. The position of the assembly plate can be adjusted by the cooperation of the support seat and the stud. After the two first clamping blocks clamp and fix the nozzle, the operator can push and adjust the position of the assembly plate to allow the second clamping block to enter the combination groove, thereby achieving longitudinal clamping and fixing of the nozzle. This ensures the positional stability of the nozzle under the cooperation of the first and second clamping blocks, preventing the positional displacement caused by the force of the processing tool on the nozzle during processing. When the second clamping block enters the combination groove, the fitting block is located inside the fitting groove. The fitting block can lock the two first clamping blocks a second time, ensuring the stability between the two first clamping blocks and further enhancing the support and fixing effect on the workpiece.

[0008] Specifically, the lower outer wall of the fixed platform is screwed with a circular array of support columns, and the lower outer wall of the support columns is provided with a circular array of fixing holes.

[0009] By adopting the above technical solution, the multi-point support columns can evenly distribute the weight of the fixture, providing more stable support, and the fixture can be easily fixed in the working position by means of external bolts passing through the fixing holes.

[0010] Specifically, a drive shaft is rotatably mounted at the center of the fixed platform. A circular array of connectors is mounted on the upper end of the outer wall of the drive shaft. The drive shaft is connected to the lower outer wall of the processing table by screws through the connectors. A geared motor is screwed to one side of the lower outer wall of the fixed platform. The output end of the geared motor is connected to the drive shaft by a coupling.

[0011] By adopting the above technical solution, the geared motor provides power to the drive shaft. Through the coupling, the rotation speed and angle of the processing table can be precisely controlled, improving the flexibility and accuracy of processing. The connecting parts ensure the stability of the connection between the drive shaft and the processing table, ensuring that the rotation of the drive shaft enables the processing table to rotate synchronously. The geared motor is controlled by an external controller, which can control the speed of the nozzle. When the nozzle is securely clamped and driven to rotate, the tool of the external CNC equipment feeds with the nozzle as the origin. When the tool reaches the required depth, the tool only needs to be driven to move linearly to complete the processing of the annular groove on the outside of the dispensing nozzle.

[0012] Specifically, the outer wall of the first clamping block is threaded with a limiting sleeve for restricting the rotation space, and the end of the screw is located inside the limiting sleeve.

[0013] By adopting the above technical solution, when the operator manually rotates the screw, the end of the screw rotates inside the limiting sleeve. The setting of the limiting sleeve restricts the rotation space of the screw, so the rotation and movement of the screw will push the first clamping block to move horizontally, thereby achieving the purpose of adjusting the position of the first clamping block.

[0014] Specifically, nuts are threaded onto the outer walls of both sides of the stud, and the two nuts are distributed on both sides of the support base.

[0015] By adopting the above technical solution, the position of the stud can be precisely adjusted and fixed in the required position by tightening or loosening the nut, thereby achieving precise control of the assembly plate position.

[0016] Specifically, a second clamping block is screwed to the outer wall of one side of the assembly plate. The second clamping block is located inside the combination groove. Both sides of the inner wall of the first clamping block are designed with an inclined shape. The inner wall shape of the second clamping block is adapted to the inner wall shape of the first clamping block.

[0017] By adopting the above technical solution, the second clamping block can achieve a tight fit with the first clamping block, forming a more reliable clamping structure, effectively preventing the dispensing nozzle from shaking during processing and improving processing quality.

[0018] Specifically, the outer wall of the assembly plate is screwed with a rectangular array of interlocking blocks. The interlocking blocks are designed in an L-shape. The size of the interlocking blocks is smaller than the inner wall size of the interlocking groove, and the interlocking blocks are located inside the interlocking groove.

[0019] By adopting the above technical solution, the interlocking block and the interlocking groove cooperate to further enhance the connection stability and positioning accuracy between the assembly plate and the first clamping block, ensuring reliable clamping of the workpiece.

[0020] Specifically, the upper outer wall of the fixed base is provided with sliding grooves on both sides, and the lower outer wall of the first clamping block is provided with a slider, which is slidably installed inside the sliding groove.

[0021] By adopting the above technical solution, the slider and the groove make the first clamping block move more smoothly during the movement process. At the same time, the groove also plays a guiding role, ensuring that the movement direction of the first clamping block is accurate.

[0022] The beneficial effects of this utility model are:

[0023] (1) The present invention provides a special rotary fixture for CNC equipment for dispensing nozzles. The two first clamping blocks clamp the nozzle, ensuring the horizontal clamping and fixing of the nozzle. The second clamping block enters the combined groove, which can achieve the vertical clamping and fixing of the nozzle. This ensures the positional stability of the nozzle under the cooperation of the first clamping block and the second clamping block, avoids the force of the processing tool on the nozzle during processing, which causes the nozzle to shift in position, ensures the processing quality of the nozzle, and reduces the defect rate.

[0024] (2) The rotary fixture for CNC equipment for dispensing nozzles described in this utility model has a fitting block and a fitting groove that can lock the two first clamping blocks a second time, ensuring the relative stability between the two first clamping blocks and further enhancing the support and fixing effect on the workpiece.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present invention provides a rotary fixture for CNC equipment for dispensing nozzles, comprising a fixed platform 1, a fixed base 2, and a support base 3. A processing table 11 is provided on the upper outer wall of the fixed platform 1. Fixed bases 2 are installed on both sides of the upper outer wall of the processing table 11. A screw 21 is threadedly connected inside the fixed base 2. A first clamping block 22 is provided on one side of the outer wall of the screw 21. Fitting grooves 24 are symmetrically opened on both sides of the outer wall of the first clamping block 22. Combination grooves 23 are opened on both sides of the outer wall of the first clamping block 22. Support bases 3 are installed on both sides of the upper outer wall of the processing table 11. A stud 31 is movably installed inside the support base 3. An assembly plate 33 is installed on one side of the outer wall of the stud 31.

[0033] In use, the combination of the fixing base 2 and the screw 21 allows the position of the first clamping block 22 to be adjusted by rotating the screw 21, thus enabling flexible clamping according to the size and shape of the dispensing nozzle. By adjusting the position of the two first clamping blocks 22, the position of the nozzle can be adjusted to ensure that the nozzle is aligned with the axis of the processing table 11. The clamping of the nozzle by the two first clamping blocks 22 ensures the lateral clamping and fixation of the nozzle. The position of the assembly plate 33 can be adjusted by the cooperation of the support base 3 and the stud 31. After the two first clamping blocks 22 clamp and fix the nozzle, The operator can push and adjust the position of the assembly plate 33 so that the second clamping block 34 enters the combination groove 23, which can achieve longitudinal clamping and fixing of the nozzle, ensuring the positional stability of the nozzle under the cooperation of the first clamping block 22 and the second clamping block 34, and avoiding positional displacement caused by the force of the machining tool on the nozzle during machining. When the second clamping block 34 enters the combination groove 23, the fitting block 35 is located inside the fitting groove 24. The fitting block 35 can lock the two first clamping blocks 22 a second time, ensuring the stability between the two first clamping blocks 22, and further enhancing the support and fixing effect on the workpiece.

[0034] To maintain a stable position, for example, such as Figure 1 As shown, the lower outer wall of the fixed platform 1 is screwed with a circular array of support columns 12, and the lower outer wall of the support columns 12 has a circular array of fixing holes.

[0035] When in use, the multi-point support columns 12 can evenly distribute the weight of the fixture, providing more stable support, and the fixture can be easily fixed in the working position by means of external bolts passing through the fixing holes.

[0036] To drive rotation, for example, such as Figure 2As shown, a drive shaft 13 is rotatably mounted at the center of the fixed table 1. A circular array of connectors 14 are mounted on the upper end of the outer wall of the drive shaft 13. The drive shaft 13 is screwed to the lower outer wall of the processing table 11 through the connectors 14. A geared motor 15 is screwed to one side of the lower outer wall of the fixed table 1. The output end of the geared motor 15 is connected to the drive shaft 13 by a coupling.

[0037] In use, the geared motor 15 provides power to the drive shaft 13. Connected by a coupling, it can precisely control the rotation speed and angle of the processing table 11, improving the flexibility and accuracy of processing. The connecting piece 14 ensures the stability of the connection between the drive shaft 13 and the processing table 11, ensuring that the rotation of the drive shaft 13 enables the processing table 11 to rotate synchronously. The geared motor 15 is controlled by an external controller, which can control the speed of the nozzle. When the nozzle is securely clamped and driven to rotate, the tool of the external CNC equipment feeds with the nozzle as the origin. When the tool reaches the required depth, the tool only needs to be driven to move linearly to complete the processing of the annular groove on the outside of the dispensing nozzle.

[0038] To limit the rotational space, for example, such as Figure 3 As shown, the outer wall of the first clamping block 22 is threaded with a limiting sleeve 26 for limiting the rotation space, and the end of the screw 21 is located inside the limiting sleeve 26.

[0039] When in use, when the operator manually rotates the screw 21, the end of the screw 21 rotates inside the limiting sleeve 26. The setting of the limiting sleeve 26 restricts the rotation space of the screw 21, so the rotation and movement of the screw 21 will push the first clamping block 22 to move horizontally, thereby achieving the purpose of adjusting the position of the first clamping block 22.

[0040] To fix the usage location, for example, such as Figure 4 As shown, nuts 32 are threaded onto the outer walls of both sides of the stud 31, and the two nuts 32 are distributed on both sides of the support base 3.

[0041] In use, by tightening or loosening the nut 32, the position of the stud 31 can be precisely adjusted and fixed in the desired position, thereby achieving precise control of the position of the assembly plate 33.

[0042] To improve clamping stability, for example, such as Figure 4 As shown, a second clamping block 34 is screwed to one side of the outer wall of the assembly plate 33. The second clamping block 34 is located inside the combination groove 23. Both sides of the inner wall of the first clamping block 22 are designed with an inclined shape. The inner wall shape of the second clamping block 34 is adapted to the inner wall shape of the first clamping block 22.

[0043] When in use, the second clamping block 34 can achieve a tight fit with the first clamping block 22 to form a more reliable clamping structure, effectively preventing the dispensing nozzle from shaking during processing and improving processing quality.

[0044] To improve positional stability, for example, such as Figure 4 As shown, the outer wall of the assembly plate 33 is screwed with a rectangular array of interlocking blocks 35. The interlocking blocks 35 are designed in an L-shape. The size of the interlocking blocks 35 is smaller than the inner wall size of the interlocking groove 24, and the interlocking blocks 35 are located inside the interlocking groove 24.

[0045] When in use, the fitting block 35 cooperates with the fitting groove 24, which can further enhance the connection stability and positioning accuracy between the assembly plate 33 and the first clamping block 22, and ensure reliable clamping of the workpiece.

[0046] To maintain the movement trajectory, for example, such as Figure 2 As shown, the upper outer wall of the fixed base 2 has sliding grooves 16 on both sides, and the lower outer wall of the first clamping block 22 is equipped with a slider 25, which is slidably installed inside the sliding groove 16.

[0047] In use, the slider 25 and the groove 16 make the first clamping block 22 move more smoothly, and the groove 16 also plays a guiding role to ensure that the first clamping block 22 moves in an accurate direction.

[0048] When using this utility model, the support column 12 is placed in the working position, and the fixture is firmly fixed in the working position by using an external bolt through the fixing hole on the lower outer wall of the support column 12.

[0049] The dispensing nozzle is placed on the processing table 11, and the operator manually rotates the screw 21 inside the fixing seat 2. Since the end of the screw 21 rotates inside the limiting sleeve 26, the limiting sleeve 26 restricts the rotation space of the screw 21. The rotation of the screw 21 pushes the first clamping block 22 to move on the fixing seat 2. The first clamping block 22 moves smoothly and accurately in the sliding groove 16 by sliding the slider 25. According to the size and shape of the dispensing nozzle, the positions of the first clamping blocks 22 at both ends are adjusted to ensure that the nozzle can be accurately clamped, while ensuring that the nozzle is aligned with the axis of the processing table 11.

[0050] Push the assembly plate 33 so that the second clamping block 34 enters the combination groove 23 on both sides of the outer wall of the first clamping block 22. At this time, the design of the inclined shape on both sides of the inner wall of the first clamping block 22 and the second clamping block 34 is adapted to make the two fit tightly together to achieve longitudinal clamping and fixing of the nozzle. At the same time, the L-shaped fitting block 35 on the outer wall of the assembly plate 33 enters the fitting groove 24 of the first clamping block 22 to lock the two first clamping blocks 22 a second time, further enhancing the overall stability. Then, the operator locks the position of the stud 31 with the nut 32 to ensure that the use position of the assembly plate 33 is stable.

[0051] The external controller starts the geared motor 15 on one side of the lower outer wall of the fixed platform 1. The geared motor 15 drives the drive shaft 13 to rotate through the coupling. The drive shaft 13 drives the processing table 11 to rotate synchronously through the connecting piece 14. According to the processing requirements, the controller precisely controls the speed of the geared motor 15, thereby controlling the speed of the nozzle. The tool of the external CNC equipment feeds with the nozzle as the origin. When the tool reaches the required depth, the tool only needs to be driven to move linearly to complete the processing of the annular groove on the outside of the dispensing nozzle.

All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
