Description

Technical Field

[0001] This utility model belongs to the field of honing machine technology, specifically relating to a feeding mechanism for a honing machine. Background Technology

[0002] A honing machine is a grinding machine that uses a honing head to grind the surface of a workpiece for precision machining. It is mainly used to process high-precision holes in parts, such as small holes in hydraulic cylinders and valve bodies, and holes in engine cylinder bodies. With the development of technology, the requirements for the machining accuracy of various parts are becoming increasingly higher, requiring higher performance to meet machining needs.

[0003] The existing technology, patent publication number CN207548508U, describes a honing single-feed mechanism for a honing machine. The power output shaft of this patented drive device outputs rotational power via a motor drive, ensuring precise vertical movement of the honing rod and enabling quantitative feed control, constant pressure feed control, and constant pressure-quantitative feed control. The overall structure is integrated and modular, making processing and assembly easier. It allows for complete replacement during maintenance, simplifying maintenance and reducing costs. However, in practical use, the following shortcomings exist: In practice, this mechanism uses a motor to drive a lead screw, which in turn drives the honing rod feed via a nut. During high-speed relative motion, the helical surfaces of the lead screw and nut experience frictional heat due to stress concentration, causing thermal expansion of the nut. This alters the clearance between the nut and the lead screw, reducing feed accuracy. Furthermore, the honing head is typically fixed to the honing machine with screws, making disassembly difficult and hindering head replacement, thus increasing maintenance complexity.

[0004] Therefore, a new feeding mechanism for honing machines is needed to solve the problems of high temperature generated by the lead screw and nut, which reduces feeding accuracy, and the difficulty in replacing the honing head, which increases maintenance difficulty in the existing technology.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides a feeding mechanism for a honing machine, including a feed box 1, a reduction motor 2, a coupling 3, a ball screw 4, a feeding mechanism 5, and a honing rod 6. The reduction motor 2 is located above the feed box 1, the coupling 3 is fixedly connected to the output end of the reduction motor 2, the ball screw 4 is fixedly connected to the bottom of the coupling 3, the feeding mechanism 5 is located outside and below the ball screw 4, the honing rod 6 is located below the feeding mechanism 5, a connecting mechanism 7 is located below the honing rod 6, a honing head 9 is located below the connecting mechanism 7, and a fixing member 8 is provided between the honing rod 6 and the honing head 9.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the feeding mechanism 5 consists of a ball nut 501, a connecting plate 502, a guide rod 503, a connecting rod 504, a connecting column 505, a water inlet 506, a water outlet 507, and a water pipe 508. The ball nut 501 is threaded to the outside of the ball screw 4. The connecting plate 502 is symmetrically fixed to the left and right sides of the ball nut 501. The guide rod 503 is symmetrically fixed to the inside of the feed box 1, and the connecting plate 502 is slidably connected to the outside of the guide rod 503. The connecting rod 504 is symmetrically fixed to the bottom of the ball nut 501. The connecting column 505 is fixed to the bottom of the connecting rod 504. The honing rod 6 is fixed to the bottom of the connecting column 505.

[0026] Since the ball nut 501 is threaded to the outside of the ball screw 4 and the connecting plate 502 is slidably connected to the outside of the guide rod 503, the rotation of the ball nut 501 is restricted, so that the ball nut 501 can only move up and down in a straight line along the ball screw 4.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the ball nut 501 has a water storage cavity inside, the water inlet 506 is fixedly connected to the upper back of the water storage cavity, the water outlet 507 is fixedly connected to the lower front of the water storage cavity, and the water pipe 508 is connected to the water inlet 506 and the water outlet 507 respectively.

[0028] The ball nut 501 can be cooled by the water inlet 506, water outlet 507, and water pipe 508, which remove the heat generated by the ball nut 501 during its movement.

[0029] As can be seen from the above working process, coolant can be injected into the water storage chamber inside the ball nut 501 through the water inlet 506, water outlet 507 and water pipe 508, which can effectively cool the ball nut 501. During the long-term operation of the honing machine, the temperature can be effectively reduced, ensuring the stable operation of the overall mechanism, improving the feeding accuracy and extending the service life of the equipment.

[0030] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the connecting mechanism 7 consists of an upper connecting plate 701, a lower connecting plate 702, and a threaded rod 703. The upper connecting plate 701 is fixedly connected to the lower part of the honing rod 6. Threaded grooves are respectively opened inside the bottom surface of the honing rod 6 and inside the upper connecting plate 701. The threaded rod 703 is fixedly connected to the upper part of the lower connecting plate 702. The honing head 9 is fixedly connected to the lower part of the lower connecting plate 702. Mounting holes are symmetrically opened on the left and right sides of the upper connecting plate 701 and the lower connecting plate 702.

[0031] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the fixing component 8 consists of a cylinder 801, a rotating rod 803, a limiting block 804, a threaded block 805, a pressing plate 806, a sliding rod 807, a limiting post 809, and a spring 810. Three through slots 802 are symmetrically opened in the lower part of the cylinder 801. The lower end of the rotating rod 803 is rotatably connected to the inside of the through slot 802, and the limiting block 804 is fixedly connected to one side of the rotating rod 803.

[0032] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the threaded block 805 is fixedly connected to the upper part of the outer side of the cylinder 801, the clamping plate 806 is threadedly connected to the outer side of the threaded block 805, and the outer surface of the clamping plate 806 is evenly provided with anti-slip grooves. The slide rod 807 is slidably connected to the inside of the cylinder 801, and the lower part of the outer surface of the slide rod 807 is provided with a groove 808.

[0033] The limiting block 804 is set inside the groove 808. During the movement of the slide bar 807, the groove 808 will push the limiting block 804, thereby driving the rotating rod 803 to rotate, completing the opening and closing operation of the rotating rod 803.

[0034] Further as Figure 2 , Figure 4 and Figure 5As shown, it is worth noting that the limiting post 809 is fixedly connected to the lower part of the slide rod 807, the spring 810 is sleeved on the outside of the limiting post 809, the inner bottom surface of the cylinder 801 is provided with a limiting groove that matches the limiting post 809, and the spring 810 is fixedly connected between the inner bottom surface of the cylinder 801 and the bottom surface of the slide rod 807.

[0035] The honing rod 6 and the honing head 9 can be further secured by the fastener 8.

[0036] The solution has the following working process: When in use, the honing head 9 is first initially connected to the honing rod 6 through the connecting mechanism 7: Align the threaded rod 703 above the lower connecting plate 702 with the threaded groove opened inside the bottom surface of the upper connecting plate 701 and the honing rod 6, rotate the lower connecting plate 702 so that the threaded rod 703 is screwed into the threaded groove, and the initial connection is completed.

[0037] The connection between the honing rod 6 and the honing head 9 is further reinforced using the fixing component 8: First, press down the slide rod 807 to drive the lower limiting post 809 into the limiting groove, compressing the spring 810. The groove 808 then moves downwards, pressing down the limiting block 804, causing the lower end of the rotating rod 803 to rotate and retract into the through groove 802. Next, insert the cylindrical body 801 into the mounting holes of the upper connecting plate 701 and the lower connecting plate 702. Then, release the pressed slide rod 807, allowing the spring 810 to retract. The elastic force of the 0 causes the groove 808 to move upward and reset, which in turn causes the limit block 804 to move, thereby causing the rotating rod 803 to reset. This makes the top surface of the three rotating rods 803 press against the bottom surface of the lower connecting plate 702. Then, the pressure plate 806 is rotated and moved downward until the bottom surface of the pressure plate 806 presses against the top surface of the upper connecting plate 701, thus completing the fixation of the upper connecting plate 701 and the lower connecting plate 702. This further connects and fixes the upper connecting plate 701 and the lower connecting plate 702, ensuring that the honing rod 6 and the honing head 9 are firmly connected.

[0038] The geared motor 2 is started, and the geared motor 2 drives the ball screw 4 to rotate through the coupling 3. The ball nut 501 drives the honing rod 6 and the honing head 9 to move up and down through the connecting rod 504 and the connecting column 505 to realize the feeding action and perform honing on the workpiece. During the honing process, the water pipe 508 injects external coolant into the water storage chamber inside the ball nut 501 through the water inlet 506. After the coolant flows in the water storage chamber, it flows out from the water outlet 507 through the water pipe 508, which takes away the heat generated by the ball nut 501 during the movement and plays a role in cooling.

[0039] In summary: The water inlet 506, outlet 507, and water pipe 508 allow coolant to be injected into the water storage chamber inside the ball nut 501, effectively cooling the ball nut 501. This effectively reduces temperature during long-term honing operation, ensuring stable operation of the overall mechanism, improving feed accuracy, and extending equipment lifespan. The connecting mechanism 7 allows for initial connection of the honing rod 6 and honing head 9 via threaded connection, providing convenient operation and a relatively secure connection. The fixing component 8 further enhances the stability of the connection between the upper connecting plate 701 and the lower connecting plate 702, effectively preventing the honing head 9 from loosening during honing and ensuring the accuracy and quality of the honing process.
