Description

Technical Field

[0001] The invention relates to the field of plane milling fixtures, in particular to a bolt ball cutting machining positioning fixture. Background Art

[0002] Bolt balls are a key component widely used in machinery, automobiles, aerospace and other fields. Their unique spherical structure and irregular geometric shape make them face great technical challenges during milling. Bolt balls usually need to be processed with high precision, and their surfaces are smooth and prone to slight deformation. This requires that the stability and precise positioning of the workpiece must be guaranteed during processing. However, due to their spherical structure, traditional fixtures mostly use plane contact or single-point centering methods, which cannot effectively adapt to the curved surface characteristics of bolt balls. This makes it easy to have problems such as inaccurate positioning and uneven clamping force during processing, which causes parts to move, vibrate or tilt during processing, seriously affecting processing quality and efficiency.

[0003] In addition, there may be large differences in the size and spherical curvature of bolt ball parts. Traditional fixtures have poor versatility and cannot adapt to bolt ball parts of different specifications and materials, resulting in insufficient adaptability in mass production. At the same time, traditional fixtures are easily affected by vibration during high-speed milling or high-load processing. This vibration will not only reduce the processing accuracy, but may also cause additional burden on machine tools and cutting tools. In order to overcome these problems, the design of the bolt ball milling positioning fixture must have a high-precision positioning system, stable and uniform clamping force distribution, effective vibration resistance and strong adaptability to ensure the stability and efficiency of the processing process. Therefore, the innovative positioning fixture design should focus on the special clamping needs of spherical workpieces to improve processing accuracy, shorten processing cycle, and ensure that the processing quality meets industry standards.

[0004] After searching, it was found that the prior art publication number is CN109158921A, which discloses a multi-angle bolt ball matching plane milling fixture, including a supporting base plate, a workpiece supporting vertical plate and a workpiece clamping device; one end of the supporting base plate is hingedly installed and connected to one end of the workpiece supporting vertical plate, and the hinged installation position is provided with a workpiece supporting vertical plate angle control mechanism and a workpiece supporting vertical plate angle positioning locking mechanism; the workpiece clamping device includes a clamping body, a workpiece locking mechanism, a workpiece rotation angle control mechanism and a workpiece rotation angle positioning mechanism, the clamping body is arranged perpendicular to the workpiece supporting vertical plate, the workpiece locking mechanism is coaxially installed on the clamping body, the workpiece rotation angle control mechanism is arranged between the clamping body and the workpiece supporting vertical plate, and the workpiece rotation angle positioning mechanism is arranged in coordination on the clamping body and the workpiece supporting vertical plate. This scheme has a simple structure, accurate indexing, and is easy to operate, which can greatly reduce the indexing and positioning difficulty of various angle plane milling processing of porous bolt ball workpieces.

[0005] Therefore, based on the above search and in combination with the existing technology, the existing multi-angle bolt ball combined with the plane milling fixture cannot control the bolt ball to arbitrarily adjust the angle during the processing work. At the same time, the device does not have the ability of automatic cycle processing. After the processing is completed, the workpiece angle cannot be quickly adjusted and the processing cannot be continued. Manual intervention is required, which reduces production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the present invention is used, the double fixing method of the adsorption arc disk and the clamping claw realizes the stable clamping of the bolt ball body, ensuring that the workpiece will not be offset or loosened during the processing. The adsorption arc disk uses the air pressure difference to form an adsorption force, and cooperates with the mechanical clamping of the clamping claw to make the bolt ball body in a highly stable state during the processing, thereby improving the processing accuracy and reducing the scrap rate. In addition, the clamping structure can be adjusted under the condition of different diameters of the bolt ball body, ensuring wide applicability;

In particular, the mounting cylinder and the adsorption arc disk can be replaced according to the bolt ball bodies of different specifications, so that the equipment is suitable for workpieces of different sizes. On the other hand, through the design of the driving wheel and the exposed groove of the rotating assembly, the bolt ball body can be rotated and adjusted at any angle in the mounting cylinder to meet the processing requirements of different angles.

[0020] 3. When the present invention is in use, by cleverly utilizing the air pressure control system, during the adsorption, clamping, and release operations, the internal air pressure can be accurately adjusted to achieve efficient fixation and rapid release of the workpiece. When the clamping jaws move forward, the internal gas is continuously discharged, thereby enhancing the adsorption force of the adsorption arc disk; and when the clamping jaws are released and the pressure relief device is started, the outside air is quickly replenished, so that the workpiece can be smoothly released and the angle can be adjusted, so that the device has automatic cycle processing capabilities. After the processing is completed, the workpiece angle can be quickly adjusted and processing can continue without manual intervention, which greatly improves production efficiency. The processing process can be carried out continuously, avoiding downtime caused by manual adjustment or loose clamping, and further improving the working efficiency of the equipment.

[0048] The working principle of the present invention is: firstly, the connection base 61 is bolted and fixedly installed on the end of the processing arm 71 of the machine tool 7, the installation cylinder 31 and the adsorption arc disk 44 are replaced according to the outer diameter of the bolt ball body 5 to be processed, the installation cylinder 31 is fixed to the front end of the assembly cylinder body 1 by threading, and the adsorption arc disk 44 is fixed to the piston 41 by threading;

[0049] When the bolt ball body 5 is placed in the installation cylinder 31, the outer wall of the bolt ball body 5 abuts against the inner wall of the adsorption arc disk 44. The staff presses the bolt ball body 5 to make it enter the installation cylinder 31. The adsorption arc disk 44 drives the piston 41 to slide in the assembly cylinder body 1, compressing the spring 2 42. At the same time, the piston 41 transmits the excess air inside the assembly cylinder body 1 to the two air valve cylinders 64 through the two connecting pipes 65. The air pressure in the air valve cylinder 64 is greater than the pressure of the spring 4 67 on the ball valve 66, so that the spring 4 67 is compressed, and the ball valve 66 is compressed. The valve 66 is out of contact with the abutment ring 641, and the excess gas is discharged through the gas outlet opened on the rear end surface of the gas valve cylinder 64. When the gas is discharged, the spring 4 67 releases the pressure to make the outer wall of the ball valve 66 abut against the abutment ring 641. At this time, the staff cancels the pressing on the bolt ball body 5, and the spring 2 42 releases the elastic force to drive the piston 41 and the adsorption arc disk 44 to move forward. Since the assembly cylinder body 1 will not take in air anymore, the bolt ball body 5 is adsorbed in the adsorption arc disk 44 according to the air pressure, and the initial limit is performed;

[0050] Start the motor 24, the motor 24 drives the gear ring 22 to rotate through the driving gear 23, thereby driving the rotating ring 21 to rotate, and the plurality of telescopic cylinders 25 on the rotating ring 21 drive the threaded collar 27 to rotate synchronously, and the threaded collar 27 moves forward on the outer wall of the threaded sleeve 26 through the threaded transmission mode, and the threaded collar 27 drives the driving ring 28 to move forward, and the driving ring 28 controls the plurality of clamping claws 32 to rotate at the front end of the installation tube 31 through the plurality of connecting rods 33, so as to control the clamping force of the plurality of clamping claws 32 on the bolt ball body 5, and in the process that the plurality of clamping claws 32 continuously press the bolt ball body 5 into the installation tube 31, the gas inside the assembly tube body 1 is continuously pressed out, so as to realize the enhancement of the adsorption force of the adsorption arc disk 44 on the bolt ball body 5, until the bolt ball body 5 cannot rotate under the adsorption force of the adsorption arc disk 44 and the holding force of the plurality of clamping claws 32, and the motor 24 stops working, and the bolt ball body 5 is milled by controlling the machine tool 7;

[0051] When one side of the bolt ball body 5 needs to be replaced after machining, the motor 1 24 is started to reverse, and the motor 1 24 drives the gear ring 22 to rotate through the driving gear 23, thereby driving the rotating ring 21 to rotate, and the plurality of telescopic cylinders 25 on the rotating ring 21 drive the threaded collar 27 to rotate synchronously, and the threaded collar 27 moves backward on the outer wall of the threaded sleeve 26 through the threaded transmission mode. In this process, the clamping force of the plurality of clamping claws 32 on the bolt ball body 5 is gradually weakened, but the clamping limit effect does not disappear, and the threaded collar 27 moves backward until the trigger rod 271 on the threaded collar 27 contacts the ring 6 in the pressure relief assembly 6. 2. At this time, the spring three 63 is compressed, and the light rod 621 drives the connecting head 622 to move backward. As the connecting rope 68 is tightened, the connecting head 622 pulls the ball valve 66 backward through the connecting rope 68, and the spring four 67 is compressed, so that the ball valve 66 is separated from the contact with the abutment ring 641. Since the internal air pressure of the assembly cylinder body 1 is lower than the external air pressure at this time, the external air flows into the assembly cylinder body 1 through the two air valve cylinders 64 until the external air pressure is balanced with the internal air pressure of the assembly cylinder body 1. At this time, the adsorption arc disk 44 cancels the adsorption force on the bolt ball body 5, and the bolt ball body 5 can rotate freely in the installation cylinder 31.

[0052] Start the rotating assembly 34, and drive the two driving wheels 342 to rotate through the two motors 344. The two springs 1 343 provide downward elastic force to the movable bracket 341, so that the outer walls of the two driving wheels 342 abut against the outer wall of the bolt ball body 5 after passing through the two exposed grooves. The outer walls of the two driving wheels 342 are made of rubber, which can effectively increase the friction of the driving wheels 342. Since the two driving wheels 342 are perpendicular to each other, the bolt ball body 5 can rotate at any angle in the installation tube 31 to adjust its own angle;

[0053] When the angle of the bolt ball body 5 is adjusted, the motor 24 is started to rotate forward, and the threaded collar 27 is driven to move forward on the outer wall of the threaded collar 26 through a threaded transmission mode. The threaded collar 27 drives the driving ring 28 to move forward, and the driving ring 28 controls the plurality of clamping claws 32 to rotate at the front end of the installation tube 31 through a plurality of connecting rods 33, so as to control the clamping force of the plurality of clamping claws 32 on the bolt ball body 5, and the plurality of clamping claws 32 press the bolt ball body 5 into the installation tube 31 again. During this process, the gas inside the assembly tube body 1 is continuously pressed out, so as to realize the adsorption of the bolt ball body 5 by the adsorption arc disk 44, until the bolt ball body 5 cannot rotate under the adsorption force of the adsorption arc disk 44 and the clamping force of the plurality of clamping claws 32, the motor 24 stops working, and the bolt ball body 5 is milled again by controlling the machine tool 7, and this cycle is repeated until the outer wall of the bolt ball body 5 is processed; at this point, the work of the device is completed.
