Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and more specifically, to a ball head grinding machine. Background Technology

[0002] In the field of mechanical manufacturing, grinding equipment is often used to process parts. For example, in automotive parts manufacturing, to ensure the fit of ball joints with other components and to guarantee the stable operation of the steering and suspension systems, manufacturers often grind the ball joints. This requires a ball joint grinding machine to polish the surface of the ball joint and adjust its precision, thereby improving its quality and performance to meet the high standards of automotive production. However, in existing ball joint grinding processes, traditional devices lack grinding angle adjustment capabilities. This means that during grinding, the machine cannot simulate the corresponding force angle based on the actual operating conditions of the ball joint. Consequently, the ground ball joints may exhibit poor fit accuracy during actual assembly and use. As a critical automotive component, the ball joint is prone to accelerated wear with other parts under complex driving conditions, increasing the potential for malfunctions in related automotive systems. This not only affects the safety and reliability of the vehicle, leading to increased maintenance costs and shortened lifespan, but also increases after-sales costs for the company due to product quality issues, ultimately impacting the company's market competitiveness and economic benefits.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the setting of the first transmission mechanism, enables the user to control the swinging reciprocating motion of the drive rocker arm, thereby improving the device's ability to adjust the ball head grinding angle. After turning on the first motor, the user can drive the first worm gear through the motor shaft end.

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

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

[0028] The placement plate 15 is provided with a loading box 16, which is placed on the placement plate 15 and connected to the placement plate 15. The loading box 16 is equipped with a first transmission mechanism, which provides power support for driving the movement of the rocker arm 17 and is the core of the power for driving the movement of the rocker arm 17.

[0029] The first transmission mechanism includes two sets of first bearing discs 23 and a first worm gear 24. The two sets of first bearing discs 23 are located on both sides of the loading box 16 and connected to it, providing stable support for the first worm gear 24 and ensuring its smooth rotation, thus achieving smooth power transmission. The first worm gear 24 passes through the loading box 16, with both ends threaded onto the two sets of first bearing discs 23. A first worm shaft 25 is mounted on the loading box 16 and connected to it. A first worm wheel 26 is fitted onto the first worm shaft 25. The first worm gear 24 and the first worm wheel 26 mesh with each other to form a transmission combination. When the first motor 18 starts, its shaft drives the first worm gear 24 to rotate. The first worm gear 24, through meshing with the first worm wheel 26, transmits rotational power to the first worm shaft 25, causing the first worm shaft 25 to rotate. This realizes the power transmission from the motor to the first worm shaft 25, laying the power foundation for driving the swinging motion of the rocker arm 17.

[0030] A drive rocker arm 17 is provided on one side of the loading box 16. The drive rocker arm 17 is sleeved on the first worm shaft 25 and connected to the first worm shaft 25. The rotation of the first worm shaft 25 will directly drive the drive rocker arm 17 to perform a swinging reciprocating motion within a specific angle range. This swinging motion provides power for the movement of the grinding column 43, enabling the grinding column 43 to perform grinding operation on the ball head on the grinding disc 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 mounted on the first base 14 and connected to the first base 14. It serves as the power source for the first transmission mechanism. The shaft end of the first motor 18 is connected to the first worm gear 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 to drive the first worm gear 24 to rotate. It continuously provides power support to the first transmission mechanism, ensuring that the swinging motion of the rocker arm 17 can be carried out continuously and stably.

[0032] Multiple sets of support brackets 19 are provided on the placement base 11. These support brackets 19 are firmly fixed to the upper surface of the placement base 11, acting as multiple evenly distributed support points to provide stable support for the fixing plate 21. This ensures the stability of the fixing plate 21 on the placement base 11, enabling it to bear the weight of the components placed on it and preventing displacement or shaking during equipment operation. The fixing plate 21 is connected to the multiple sets of support brackets 19, providing a mounting surface for the second motor 33. The fixing plate 21 allows the second motor 33 to be stably mounted on it and remains stable during equipment operation, providing a foundation for the normal operation of the second transmission mechanism. A grinding disc 48 is provided above the placement base 11, connected to the placement base 11 via the second transmission mechanism, for grinding the ball head.

[0033] The grinding disc 48 rotates stably under the drive of the second transmission mechanism, providing the necessary circumferential motion for grinding the ball head. The stability of its rotation directly affects the grinding quality and effect of the ball head. Felt rings 37 are provided on both the loading box 16 and the placement base 11, with multiple sets of felt rings 37 respectively fitted onto the first worm 24 and the second worm 27.

[0034] The main function of the felt ring 37 is sealing and lubrication. On the one hand, it effectively prevents external dust and impurities from entering the transmission mechanism, avoiding wear on the worm and other components and ensuring transmission stability. On the other hand, the felt ring 37 has a certain oil absorption capacity, storing and slowly releasing lubricating oil to provide 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 long-term stable operation of the transmission mechanism. The grinding disc 48 includes a base 38 and a ball cup 39. The ball cup 39 is fixed to the base 38 by a pin. The base 38 provides a stable mounting foundation for the ball cup 39, ensuring that the ball cup 39 will not loosen or shift during the rotation of the grinding disc 48.

[0035] The ball cup 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 cup 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 the complete grinding of the ball head neck part, thereby improving the overall grinding quality of the ball head.

[0036] The grinding column includes a connecting rod 43 and a grinding ball 44 disposed at one end of the connecting rod 43. The connecting rod 43 serves to connect and transmit motion, transmitting the swinging motion of the drive rocker arm 17 to the grinding ball 44. The grinding ball 44, as the component that directly contacts the ball head for grinding, performs a grinding operation on the ball head on the grinding disc 48 under the drive of the drive rocker arm 17. Through friction with the surface of the ball head, the grinding process is achieved on the surface of the ball head to achieve the required surface quality.

[0037] The connector includes a small shaft 45 and a connecting block 46. The small shaft 45 passes through the drive rocker arm 17 and is connected to the drive rocker arm 17. The connecting block 46 is located 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 arrangement realizes the effective connection between the drive rocker arm 17 and the grinding column 43, so that the swinging motion of the drive rocker arm 17 can be accurately transmitted to the grinding column 43, thereby driving 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 using this device, the placement base 11 is located at the bottom of the ball head grinding area, serving as the supporting foundation for the entire device. It provides a place for the support bracket 12 and other components, bearing the weight of each component of the grinding machine. The support bracket 12 is connected to one side of the placement base 11, and the support bracket 12 is vertically fixed to one side of the placement base 11, providing vertical support for the vertically fixed arm 13. The vertically fixed arm 13 is mounted on the support bracket 12, perpendicular to and fixed to it, providing installation positions for the first base 14 and the placement plate 15. The first base 14 is located on one side of the vertically fixed arm 13, connected to the vertically fixed arm 13, providing an installation location for the first motor 18. The placement plate 15 is mounted on the vertically fixed arm 13, connected to it, and used to support the loading box 16. The loading box 16 is mounted on the placement plate 15, placed on and connected to it. The first transmission mechanism is installed inside the loading box 16, providing power for the movement of the rocker arm 17.

[0039] The first transmission mechanism has two sets of first bearing discs 23 and a first worm gear 24. The two sets of first bearing discs 23 are located on both sides of the loading box 16, and the first worm gear 24 passes through the loading box 16 and is threaded onto the two sets of first bearing discs 23. The first bearing discs 23 provide support for the first worm gear 24, allowing it to rotate. A first worm shaft 25 is mounted on the loading box 16 and connected to it. A first worm wheel 26 is fitted onto the first worm shaft 25, and the first worm gear 24 meshes with the first worm wheel 26. The shaft end of the first motor 18 is connected to the first worm gear 24. When the first motor 18 starts, it drives the first worm gear 24 to rotate, which in turn drives the first worm wheel 26, causing the first worm shaft 25 to rotate, thus achieving power transmission. A drive rocker arm 17 is provided on one side of the loading box 16. The drive 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 drive rocker arm 17 to make a swinging reciprocating motion. The swing angle α of the drive rocker arm 17 is between -10° and 10°, providing power for the movement of the grinding column 43.

[0040] The first base 14 is equipped with a first motor 18, which is mounted on and connected to the first base 14. The shaft end of the first motor 18 is connected to the first worm gear 24, which is the power source of the first transmission mechanism. The placement base 11 is equipped with multiple sets of support brackets 19, which are fixed on the upper surface of the placement base 11 to provide support for the fixing plate 21. The fixing plate 21 is mounted on the multiple sets of support brackets 19 and is connected to the multiple sets of support brackets 19 for mounting components such as the second motor 33. A grinding disc 48 is provided above the placement base 11, which is connected to the placement base 11 through the second transmission mechanism for grinding ball heads.

[0041] The second transmission mechanism on the base 11 for rotating the grinding disc 48 includes a second worm gear 27 and two sets of second bearing discs 28. The second worm gear 27 passes through the base 11 and onto the two sets of second bearing discs 28, which are respectively mounted at corresponding positions on the base 11, providing support for the second worm gear 27 to enable its rotation. Third bearing covers 29 are provided on both sides of the base 11, connected to the base 11 and mounted at corresponding positions on both sides, providing axial positioning and protection for the second worm shaft 31 passing through it.

[0042] Two sets of third bearing covers 29 are fitted with second worm shafts 31, which are connected to the third bearing covers 29. A second worm wheel 32 is fitted onto the second worm shaft 31, and the second worm wheel 32 meshes with the second worm 27. The rotation of the second worm 27, through its meshing with the second worm wheel 32, drives the second worm shaft 31 to rotate, thereby driving the grinding disc 48 to rotate. Felt rings 37 are provided on both the loading box 16 and the placement base 11, with multiple sets of felt rings 37 respectively fitted onto the first worm 24 and the second worm 27. The felt rings 37 prevent external dust and impurities from entering the transmission mechanism, and also store lubricating oil to provide lubrication for the worm rotation, reducing friction between the worm and other components and extending the service life of the transmission components. The grinding disc 48 is fitted onto the second worm shaft 31, and the rotation of the second worm shaft 31 drives the grinding disc 48 to rotate for ball head grinding. The grinding disc 48 includes a base 38 and a ball cup 39, with the ball cup 39 fixed to the base 38 by a pin. The base 38 provides a mounting base for the ball cup 39, which is equipped with a grinding sleeve 41 and a cross sleeve 42 for grinding the ball head neck.

[0043] The grinding column 43 includes a connecting rod 43 and a grinding ball 44, with the grinding ball 44 disposed at one end of the connecting rod 43. The connecting rod 43 connects the drive rocker arm 17 and the grinding ball 44, transmitting motion. A connecting component includes a small shaft 45 and a connecting block 46. The small shaft 45 passes through and connects to the drive rocker arm 17, while 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 drive rocker arm 17 and the grinding column 43. This allows the drive rocker arm 17 to move, driving the grinding column 43, which in turn drives the grinding ball 44 to grind the ball head.

[0044] The specific usage and function of this utility model are as follows:

[0045] In actual operation, the power is first turned on to start the first motor 18 and the second motor 33. After the first motor 18 is turned on, its shaft drives the first worm 24 connected to it to rotate. The first worm 24 meshes with the first worm wheel 26, causing the first worm shaft 25 to rotate. This, in turn, drives the drive rocker arm 17 sleeved on the first worm shaft 25 to swing back and forth within an angle range of -10° to 10°. At the same time, the shaft of the second motor 33 rotates and is connected to the pulley 35 sleeved on the second worm 27 via a belt, driving the second worm 27 to rotate. The second worm 27 meshes with the second worm wheel 32, causing the second worm shaft 31 to rotate, thereby driving the grinding disc 48 sleeved on the second worm shaft 31 to start rotating. At this time, the ball head to be ground is placed in the ball cup 39 of the grinding disc 48. The ball cup 39 is fixed to the base 38 by a pin. The grinding sleeve 41 and cross sleeve 42 on the ball cup 39 position the neck of the ball head. The swinging motion of the drive rocker arm 17 is transmitted to the grinding column through the connecting piece 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 change position continuously, making full contact with the grinding ball 44, simulating the actual working conditions of the ball head, and realizing grinding. The placement base 11 serves as the basic support of the entire equipment, bearing the weight of each component and ensuring 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 be stably installed on the first base 14 and the placement plate 15. The first base 14 provides an installation position for the first motor 18, while the placement plate 15 supports the loading box 16. The first transmission mechanism within the loading box 16 provides power to the drive rocker arm 17. Multiple sets of support brackets 19 are fixed to the upper surface of the placement base 11, supporting the fixing plate 21, which is used to install components such as the second motor 33. Felt rings 37 on the loading box 16 and the placement base 11 are respectively fitted onto the first worm 24 and the second worm 27, serving a sealing and lubricating function to prevent dust and impurities from entering the transmission mechanism, reduce friction between the worm and other components, extend the service life of the transmission components, and ensure stable operation of the transmission system. This configuration allows the ball head grinder to simulate the actual movement of the ball head during use, improving the grinding quality of the ball head through the coordination of the rocker arm 17's swaying and the grinding disc 48's rotation.

[0046] It should be noted that, in order to simplify the description of this utility model and thus help in understanding one or more embodiments of the utility model, multiple features may sometimes be grouped into one embodiment, drawing or description thereof in the foregoing description of the embodiments of this utility model.
