[0001] The present invention relates to the technical field of grinding machines, in particular to a ball head grinding machine. Background Art

[0002] In the field of mechanical manufacturing, grinding equipment is often required to process parts. For example, in automotive parts manufacturing, manufacturers often grind ball heads to ensure that they fit well with other components and maintain stable operation of the vehicle's steering and suspension systems. In this case, a ball head grinder is needed to polish the ball head surface and adjust its precision, thereby improving its quality and performance to meet the high standards required by automotive production. However, in existing ball head grinding processes, traditional devices lack a grinding angle adjustment function. As a result, the grinding process cannot simulate the corresponding force angle according to the actual operating conditions of the ball head. As a result, the ground ball head will experience poor fitting accuracy during actual assembly and use. As a key automotive component, the ball head is susceptible to increased wear between the ball head and other components under the complex driving conditions of the vehicle, which can easily increase the potential for failure of related vehicle systems. This not only affects the safety and reliability of the vehicle, resulting in increased maintenance costs and shortened service life, but also increases the company's after-sales costs due to product quality issues, thereby affecting the company's market competitiveness and economic benefits.

[0026] The present invention will be described in detail below with reference to the accompanying drawings;

[0027] like Figures 1 to 3 As shown, the present invention provides a ball head grinder, wherein one side of the placement base 11 is connected to the support bracket 12, and the support bracket 12 is vertically fixed to one side of the placement base 11, like an upright pillar, providing essential vertical support to the vertical fixed arm 13, so that the vertical fixed arm 13 can be firmly established on the placement base 11, and a vertical fixed arm 13 is provided on the support bracket 12, and the vertical fixed arm 13 is perpendicular to the support bracket 12 and firmly fixed on the support bracket 12, providing an installation position for the first machine base 14 and the placement plate 15, so that various components can be installed and work together, and a first machine base 14 is provided on one side of the vertical fixed arm 13, and the first machine base 14 is connected to the vertical fixed arm 13, providing an installation place for the first motor 18, so that the first motor 18 can be firmly placed therein and continuously provide power for the operation of the equipment. A placement plate 15 is provided on the vertical fixed arm 13, and the placement plate 15 is connected to the vertical fixed arm 13. Its function is to carry the loading box 16 and provide a horizontal and stable placement space for the loading box 16 to ensure that the loading box 16 does not shake during the operation of the equipment.

[0028] A loading box 16 is provided on the placement plate 15. The loading box 16 is placed on the placement plate 15 and is connected to the placement plate 15. A first transmission mechanism is installed inside the loading box 16 to provide power support for the movement of the driving rocker arm 17. It is the power core of the driving rocker arm 17.

[0029] The first transmission mechanism includes two sets of first bearing plates 23 and a first worm gear 24. The two sets of first bearing plates 23 are located on either side of the loading box 16 and are connected to the loading box 16. They provide stable support for the first worm gear 24, ensuring smooth rotation within the loading box and achieving smooth power transmission. The first worm gear 24 passes through the loading box 16, with its ends respectively attached to the two sets of first bearing plates 23. A first worm shaft 25 is threaded through the loading box 16 and connected to the loading box 16. A first worm gear 26 is mounted on the first worm shaft 25. The first worm gear 26 meshes with the first worm gear 26 to form a transmission assembly. When the first motor 18 is started, its shaft end drives the first worm gear 24 to rotate. The first worm gear 24, through engagement with the first worm gear 26, transmits rotational power to the first worm shaft 25, causing the first worm shaft 25 to rotate. This transfers power from the motor to the first worm shaft 25, providing the driving force for the swinging motion of the rocker arm 17.

[0030] A driving rocker arm 17 is provided on one side of the loading box 16. The driving rocker arm 17 is sleeved on the first worm shaft 25 and is connected to the first worm shaft 25. The rotation of the first worm shaft 25 will directly drive the driving rocker arm 17 to perform a swinging reciprocating motion within a specific angle range. The swinging motion provides power for the movement of the grinding column 43, so that the grinding column 43 can grind the ball head on the grinding disk 48 according to a preset trajectory, simulating the movement state of the ball head in actual use, and improving the degree and effect of grinding.

[0031] A first motor 18 is provided on the first machine base 14. The first motor 18 is installed on the first machine base 14 and is connected to the first machine base 14. It serves as the power source of the first transmission mechanism. The shaft end of the first motor 18 is connected to the first worm 24. When the first motor 18 is powered on and started, it converts electrical energy into mechanical energy and outputs stable power through the shaft end, driving the first worm 24 to rotate, continuously providing power support for the first transmission mechanism, ensuring that the swinging motion of the driving rocker arm 17 can be carried out continuously and stably.

[0032] The placement base 11 is provided with multiple sets of support brackets 19, which are firmly fixed to the upper surface of the placement base 11, like multiple evenly distributed support points, and together provide stable support for the fixed plate 21, ensuring the stability of the fixed plate 21 on the placement base 11, so that it can bear the weight of the components placed thereon, and will not be displaced or shaken during the operation of the equipment. A fixed plate 21 is provided on the multiple sets of support brackets 19, and the fixed plate 21 is connected to the multiple sets of support brackets 19 to provide a mounting surface for the second motor 33. The fixed plate 21 allows the second motor 33 to be stably mounted thereon and remains stable during the operation of the equipment, providing a basis for the normal operation of the second transmission mechanism. A grinding disc 48 is provided above the placement base 11, and the grinding disc 48 is connected to the placement base 11 through the second transmission mechanism to perform a grinding operation on the ball head.

[0033] Driven by the second transmission mechanism, the grinding disc 48 rotates stably, providing the circular motion required for grinding the ball head. The stability of its rotation directly affects the quality and effectiveness of the grinding process. Both the loading box 16 and the base 11 are equipped with felt rings 37 . Multiple sets of felt rings 37 are respectively mounted on the first worm 24 and the second worm 27 .

[0034] The main functions of the felt ring 37 are sealing and lubrication. On the one hand, it can effectively prevent external dust and impurities from invading the transmission mechanism, preventing these debris from causing wear on the worm and other components, thereby ensuring transmission stability. On the other hand, the felt ring 37 has a certain oil absorption capacity, which can store lubricating oil and slowly release it, providing continuous lubrication for the rotation of the worm, reducing friction between the worm and other components, extending the service life of the transmission components, and ensuring the long-term stable operation of the transmission mechanism. The grinding disc 48 includes a base 38 and a ball bowl 39. The ball bowl 39 is fixed to the base 38 by a pin. The base 38 provides a stable mounting base for the ball bowl 39, ensuring that the ball bowl 39 will not loosen or move during the rotation of the grinding disc 48.

[0035] The ball bowl 39 is provided with a grinding sleeve 41 and a cross sleeve 42 for grinding the ball head neck. The grinding sleeve 41 and the cross sleeve 42 are connected to the ball bowl 39. During the ball head grinding process, they can position the ball head neck so that the grinding operation can be accurately performed on the ball head neck part, ensuring that the ball head neck part is completely ground, thereby improving the overall grinding quality of the ball head.

[0036] The grinding column comprises a connecting rod 43 and a grinding ball 44 mounted at one end of the connecting rod 43. The connecting rod 43 serves to connect and transmit motion, transmitting the rocking motion of the driving rocker arm 17 to the grinding ball 44. As the component that directly contacts and grinds the ball head, driven by the driving rocker arm 17, the grinding ball 44 grinds the ball head on the grinding disc 48. Through friction with the ball head surface, the grinding process is completed, achieving the desired surface quality.

[0037] The connecting part includes a small shaft 45 and a connecting block 46. The small shaft 45 is passed through the driving rocker arm 17 and is connected to the driving rocker arm 17. The connecting block 46 is arranged at one end of the connecting rod 43 and is connected to the connecting rod 43. The connecting block 46 is connected to the small shaft 45 through the connecting rod 47. This setting realizes the effective connection between the driving rocker arm 17 and the grinding column 43, so that the swinging motion of the driving rocker arm 17 can be accurately transmitted to the grinding column 43, and then drive the grinding ball 44 to grind the ball head, ensuring the smooth progress of the grinding work and ensuring that the ball head can be ground according to the preset requirements to achieve a better grinding effect.

[0038] Figures 1 to 3 、 Figures 6 to 8As shown, when the device is in use, the placement base 11 is located at the bottom of the ball-end grinding area and serves as the load-bearing foundation for the entire equipment. It provides a place for the support bracket 12 and other components, and bears the weight of the grinding machine components. One side of the placement base 11 is connected to the support bracket 12, which is vertically fixed to one side of the placement base 11, providing vertical support for the vertical fixed arm 13. A vertical fixed arm 13 is mounted on the support bracket 12, perpendicular to and fixed to the support bracket 12, providing a mounting position for a first machine base 14 and a placement plate 15. A first machine base 14 is mounted on one side of the vertical fixed arm 13, connected to the vertical fixed arm 13, and providing a mounting position for a first motor 18. A placement plate 15 is mounted on the vertical fixed arm 13 and connected to the vertical fixed arm 13, which supports a loading box 16. The loading box 16 is mounted on the placement plate 15 and connected to the placement plate 15. The loading box 16 houses a first transmission mechanism that provides power to drive the rocker arm 17.

[0039] The first transmission mechanism has two sets of first bearing discs 23 and a first worm 24. The two sets of first bearing discs 23 are respectively on both sides of the loading box 16, and the first worm 24 passes through the loading box 16 and is inserted into the two sets of first bearing discs 23. The first bearing discs 23 provide support for the first worm 24, allowing the first worm 24 to rotate. A first worm shaft 25 is inserted into the loading box 16, and the first worm shaft 25 is connected to the loading box 16. The first worm wheel 26 is mounted on the first worm shaft 25, and the first worm 24 is engaged with the first worm wheel 26. The shaft end of the first motor 18 is connected to the first worm 24. When the first motor 18 is started, it drives the first worm 24 to rotate, and the first worm 24 drives the first worm wheel 26, causing the first worm shaft 25 to rotate, thereby realizing power transmission. A driving rocker arm 17 is provided on one side of the loading box 16. The driving rocker arm 17 is sleeved on the first worm shaft 25 and connected to it. The rotation of the first worm shaft 25 drives the driving rocker arm 17 to perform a swinging reciprocating motion. The swing angle range α of the driving rocker arm 17 is between -10° and 10°, providing power for the movement of the grinding column 43.

[0040] A first motor 18 is provided on the first machine base 14. The first motor 18 is installed on the first machine base 14 and is connected to it. The shaft end of the first motor 18 is connected to the first worm 24, which is the power source of the first transmission mechanism. A plurality of groups of support supports 19 are provided on the placement base 11. The plurality of groups of support supports 19 are fixed on the upper surface of the placement base 11 to provide support for the fixed plate 21. A fixed plate 21 is provided on the plurality of support supports 19. The fixed plate 21 is connected to the plurality of support supports 19 for installing the second motor 33 and other components. A grinding disc 48 is provided above the placement base 11. The grinding disc 48 is connected to the placement base 11 through a second transmission mechanism for grinding the ball head.

[0041] The second transmission mechanism on the base 11, used to rotate the grinding disc 48, includes a second worm 27 and two sets of second bearing discs 28. The second worm 27 passes through the base 11 and is threaded onto the two sets of second bearing discs 28. The two sets of second bearing discs 28 are mounted at corresponding locations on the base 11, providing support for the second worm 27 and enabling its rotation. Third bearing caps 29 are mounted on either side of the base 11. These caps are connected to the base 11 and mounted at corresponding locations on either side of the base 11, providing axial positioning and protection for the second worm shaft 31 extending therethrough.

[0042] The two sets of third bearing caps 29 are fitted with second worm shafts 31. These second worm shafts 31 are connected to the third bearing caps 29. A second worm wheel 32 is mounted on the second worm shafts 31, which mesh with the second worm 27. Rotation of the second worm 27, through engagement with the second worm wheel 32, drives the second worm shaft 31, thereby rotating the grinding disc 48. Both the loading box 16 and the base 11 are equipped with felt rings 37, with multiple sets of felt rings 37 fitted over the first worm 24 and second worm 27, respectively. These felt rings 37 prevent dust and impurities from entering the transmission mechanism and also store lubricating oil for the worms, reducing friction between the worms and other components and extending the life of the transmission components. The grinding disc 48 fits over the second worm shafts 31. Rotation of the second worm shaft 31 drives the grinding disc 48, performing ball grinding. The grinding disc 48 comprises a base 38 and a bowl 39, secured to the base 38 by a latch. The seat body 38 provides a mounting base for the ball bowl 39 , and the ball bowl 39 is provided with a grinding sleeve 41 and a cross sleeve 42 for grinding the ball head neck circumference.

[0043] The grinding column 43 includes a connecting rod 43 and a grinding ball 44, which is mounted at one end of the connecting rod 43. The connecting rod 43 connects the driving rocker arm 17 and the grinding ball 44, transmitting motion. The connecting member comprises a small shaft 45 and a connecting block 46. The small shaft 45 passes through the driving rocker arm 17 and is connected to it. The connecting block 46 is connected to the connecting rod 43 at one end. The connecting block 46 is connected to the small shaft 45 via a connecting rod 47, thus connecting the driving rocker arm 17 to the grinding column 43. The movement of the driving rocker arm 17 drives the grinding column 43, which in turn drives the grinding ball 44 to grind the ball head.

[0044] Specific usage and effects of the present invention:

[0045] In actual operation, first, power is turned on to start the first motor 18 and the second motor 33. After the first motor 18 is turned on, its shaft end drives the first worm 24 connected to it to rotate. The first worm 24 engages with the first worm wheel 26, causing the first worm shaft 25 to rotate accordingly, thereby driving the driving rocker arm 17 mounted on the first worm shaft 25 to swing back and forth within an angular range of -10° to 10°; at the same time, the shaft end of the second motor 33 rotates and is connected to the pulley 35 mounted on the second worm 27 via a belt, driving the second worm 27 to rotate. The second worm 27 engages with the second worm wheel 32, causing the second worm shaft 31 to rotate, thereby driving the grinding disc 48 mounted on the second worm shaft 31 to start rotating. At this time, the ball head to be ground is placed in the ball bowl 39 of the grinding disc 48. The ball bowl 39 is fixed to the base 38 by a pin. The grinding sleeve 41 and cross sleeve 42 on the ball bowl 39 position the ball head neck. The swinging motion of the driving rocker arm 17 is transmitted to the grinding column through the connecting parts composed of the small shaft 45, the connecting block 46 and the connecting rod 47, which drives the grinding ball 44 at one end of the grinding column to grind the surface of the ball head. During the grinding process, the rotation of the grinding disc 48 causes the ball head to continuously change position and fully contact with the grinding ball 44, simulating the actual use conditions of the ball head to achieve grinding. The placement base 11 serves as the basic support of the entire equipment, bearing the weight of each component to ensure stable operation of the equipment. The support bracket 12 is vertically fixed to one side of the placement base 11, providing vertical support for the vertical fixed arm 13, so that the vertical fixed arm 13 can firmly install the first machine base 14 and the placement plate 15. The first base 14 provides an installation location for the first motor 18, and the placement plate 15 is used to support the loading box 16. The first transmission mechanism in the loading box 16 provides power for the driving rocker arm 17. Multiple sets of support brackets 19 are fixed to the upper surface of the placement base 11, supporting the fixed plate 21, and the fixed plate 21 is used to install the second motor 33 and other components. The felt ring 37 set on the loading box 16 and the placement base 11 is respectively placed on the first worm 24 and the second worm 27, which plays a sealing and lubricating role, preventing dust and impurities from entering the transmission mechanism, reducing friction between the worm and other components, extending the service life of the transmission components, and ensuring the stable operation of the transmission system. This setting allows the ball head grinder to simulate the motion state of the ball head during actual use, and improves the quality of ball head grinding by coordinating the swing of the driving rocker arm 17 and the rotation of the grinding disc 48.

[0046] It should be noted that in order to simplify the description of the present invention and thus help understand one or more embodiments of the invention, in the foregoing description of the embodiments of the present invention, multiple features are sometimes combined into one embodiment, figure or description thereof.
