Description

Technical Field

[0001] This utility model belongs to the field of milling machine technology, and in particular relates to a window milling machine for processing ball cage cages. Background Technology

[0002] A window milling machine is a type of milling machine used to process workpieces with window shapes or similar shapes. For example, in a window milling machine for processing ball cage cages, the inner and outer walls of the window of the ball cage cage can be milled to ensure that the window on the ball cage cage meets the requirements, thereby improving production efficiency and product quality.

[0003] Most window milling machines use robotic arms for loading. After the robotic arm clamps the ball cage retainer, it moves to the milling machine spindle and is clamped by a clamping mechanism. Then, the window of the ball cage retainer is milled by the milling devices on both sides. For example, Chinese patent application number (2019105249507) discloses a fully automatic special milling machine for processing ball cage retainers. Its clamping cylinder drives the clamping component through a connecting rod, which slides on the clamping device mounting seat to press the ball cage retainer onto the fixture located on the spindle mechanism, thereby fixing the ball cage retainer. However, it does not center the ball cage retainer during clamping, but only relies on the movement of the robotic arm during loading to locate its position. However, when the clamping mechanism is applied, a small axial deviation between the ball cage retainer and the spindle mechanism is likely to occur, which can easily affect the milling accuracy and product quality of the ball cage retainer window. Utility Model Content

[0018] A limiting element is inserted into the surface of the clamping plate and is used to confine the slider within the mounting hole.

[0019] In the above technical solution, further:

[0020] The mounting hole has a countersunk hole, and one end of the elastic element is located inside the countersunk hole.

[0021] In the above technical solution, further:

The two ends of the insert extend into the mounting hole, and the slider has protrusions on both sides that abut against the two ends of the insert.

[0025] In the above technical solution, further:

[0026] The surface of the slider on the side away from the axis of the circular protrusion is an arc-shaped surface.

[0027] In the above technical solution, further:

[0037] 2. By using a clamping plate and a correction component mounted on the clamping plate, after the ball cage cage is corrected by the correction component, the clamping plate can cooperate with the spindle mechanism to clamp it. Therefore, by mounting the correction component on the clamping plate, the clamping mechanism can be corrected relative to the ball cage cage before locking.

[0038] 3. By using multiple sliders and elastic elements, the elastic elements cause the sliders to push the misaligned ball cage cage for centering. The correction is completed when multiple sliders are all against the inner wall of the ball cage cage. Only then is the clamping plate and spindle mechanism used for clamping. This not only improves machining accuracy but also improves correction efficiency and ensures machining efficiency. The clamping efficiency will not be affected by the correction.

[0046] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0047] Example 1:

[0048] This embodiment provides a window milling machine for machining ball cage cages, including:

[0049] Machine body 1, with a processing table 2 installed inside;

[0050] The spindle mechanism 3 is mounted on the machining table 2, and milling devices 4 are provided on both sides of the output end;

[0051] The clamping mechanism 5 is mounted on the processing table 2, and its output end is close to the spindle mechanism 3 and is coaxially arranged with the spindle mechanism 3;

[0052] The clamping mechanism 5 includes a correction component 6 for centering the ball cage cage when clamping it;

[0053] Meanwhile, the spindle mechanism 3, the milling device 4, and other mechanisms inside the machine body 1 are all present in traditional window milling machines and are existing technologies. Those skilled in the art can learn about them from traditional window milling machines, so they will not be described in detail here.

[0054] As can be seen from this embodiment, by setting the correction component 6 in the clamping mechanism 5, the clamping mechanism 5 and the spindle mechanism 3 can center the ball cage cage when clamping it, so that the ball cage cage and the spindle mechanism 3 are axially aligned, thereby effectively improving the machining accuracy and product quality.

[0055] Example 2:

[0056] This embodiment provides a window milling machine for machining ball cage cages. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the clamping mechanism 5 includes:

[0057] The base 50 is mounted on the processing table 2 by means of a first driving component 51;

[0058] The clamping plate 52 is mounted on the side of the base 50 near the main shaft mechanism 3 by means of a second driving member 53;

[0059] The calibration component 6 is installed at the clamping plate 52, and the clamping plate 52 is coaxially arranged with the spindle mechanism 3.

[0060] Meanwhile, the first driving component 51 can adopt a lead screw transmission device and a drive motor, which are existing technologies and will not be described in detail here.

[0061] As can be seen from this embodiment, by using the clamping plate 52 and the correction component 6 installed on the clamping plate 52, after the ball cage cage is corrected by the correction component 6, the clamping plate 52 can cooperate with the spindle mechanism 3 to clamp. Therefore, by installing the correction component 6 on the clamping plate 52, the clamping mechanism 5 can be corrected relative to the ball cage cage before locking, thus ensuring clamping accuracy and machining accuracy.

[0062] Furthermore, the first driving component 51 drives the base 50 to achieve pre-clamping of the ball cage cage, that is, the robot arm is retracted at this time, and then the second driving component 53 drives the correction and clamping, which is a step-by-step control method that is simple and convenient.

[0063] Example 3:

[0064] This embodiment provides a window milling machine for machining ball cage cages. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the correction component 6 includes:

[0065] A circular protrusion 60 is coaxially disposed on the side of the clamping plate 52 near the main spindle mechanism 3, and has multiple mounting holes 61 along the radial circumference;

[0066] Multiple sliders 62 are provided and are slidably connected in multiple mounting holes 61 respectively, and a chamfer 63 is provided on the side of the slider 62 away from the axis of the circular protrusion 60;

[0067] Multiple elastic elements 64 are provided and are installed in multiple mounting holes 61 respectively, with both ends abutting against the slider 62 and the inner wall of the mounting hole 61 respectively.

[0068] The limiting member 65 is inserted into the surface of the clamping plate 52 and is used to limit the slider 62 within the mounting hole 61;

[0069] The number of sliders 62 and mounting holes 61 is 2n, where n is a positive integer;

[0070] Meanwhile, the circular protrusion 60 and the clamping plate 52 can be integrated into one structure, and the elastic element 64 can be a spring. Multiple sliders 62 and mounting holes 61 are circumferentially spaced.

[0071] Furthermore, the correction component 6 extends into the ball cage retainer, meaning that the size of the correction component 6 is smaller than the distance between the inner wall of the window in the ball cage retainer and the surface of the ball cage retainer, in order to avoid touching the milling cutter on the milling device 4.

[0072] As can be seen from this embodiment, by using multiple sliders 62 and elastic elements 64, the elastic elements 64 cause the sliders 62 to push the offset ball cage retainer to center it, and the correction is completed when multiple sliders 62 abut against the inner wall of the ball cage retainer. Only then does the clamping plate 52 cooperate with the spindle mechanism 3 to perform clamping, which not only improves the machining accuracy, but also improves the correction efficiency and ensures the machining efficiency, and the clamping efficiency will not be affected by the correction.

[0073] The chamfer 63 on the slider 62 can not only drive the base 50 to move through the first drive member 51, so that the slider 62 cooperates with the main shaft mechanism 3 to pre-clamp the ball cage cage, thereby allowing the robot arm to withdraw, but also facilitates the sliding of the axial edge of the ball cage cage along the chamfer 63 surface and pushes the slider 62 to compress the elastic member 64 when the second drive member 53 pushes the clamping plate 52, ensuring that the slider 62 enters the ball cage cage and abuts against the inner wall of the ball cage cage, thereby performing centering correction;

[0074] Furthermore, the number of sliders 62 and mounting holes 61 is 2n, where n is a positive integer, which can effectively ensure the balance of the force acting on the inner wall of the ball cage and avoid increasing the offset of the ball cage.

[0075] Example 4:

[0076] This embodiment provides a window milling machine for machining ball cage cages, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0077] A countersunk hole 66 is provided in the mounting hole 61, and one end of the elastic element 64 is located in the countersunk hole 66.

[0078] As can be seen from this embodiment, by opening a countersunk hole 66 in the mounting hole 61, the installation stability of the elastic element 64 in the mounting hole 61 can be improved, and the force exerted by the elastic element 64 on the slider 62 after being compressed can be kept stable.

[0079] Example 5:

[0080] This embodiment provides a window milling machine for machining ball cage cages, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0081] An arc-shaped groove 54 is provided on the surface of the clamping disc 52 near the circular protrusion 60;

[0082] The limiting component 65 includes a insert 650 and a limiting plate 651;

[0083] The limiting plate 651 has an arc-shaped hole 652 corresponding to the arc-shaped groove 54, and the two ends of the insert 650 are respectively inserted into the arc-shaped groove 54 and the arc-shaped hole 652. The two ends of the insert 650 extend towards the mounting hole 61, and the slider 62 has protrusions 67 on both sides that abut against the two ends of the insert 650.

[0084] Meanwhile, the limiting plate 651 and the circular protrusion 60 can be fastened with bolts, while the protrusion 67 and the slider 62 can be integrated into one piece.

[0085] As can be seen from this embodiment, by adopting the setting of insert 650, the convenience of installing and limiting the slider 62 is improved, thereby facilitating the maintenance and replacement of the slider 62;

[0086] The arc-shaped groove 54 and the arc-shaped hole 652 can preferentially limit the two ends of the insert 650, improving the stability of the insert 650 installation. The protrusion 67 can make the insert 650 restrict the slider 62 within the mounting hole 61, preventing the slider 62 from falling out of the mounting hole 61 and improving the installation stability of the slider 62.

[0087] Example 6:

[0088] This embodiment provides a window milling machine for machining ball cage cages, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0089] The surface of slider 62 away from the axis of the circular protrusion 60 is an arc surface 68;

[0090] Among them, the arc-shaped surface 68 is adapted to the inner wall of the ball cage cage.

[0091] As can be seen from this embodiment, by forming an arc-shaped surface 68 on the surface of the slider 62, the contact area between the slider 62 and the inner wall of the ball cage is increased, which can improve the stability of the slider 62 clamping the ball cage and at the same time ensure the accuracy of the centering and correction of the ball cage.

[0092] Furthermore, when milling different ball cage cages, sliders 62 with different arc surfaces 68 can be replaced to improve adaptability.

[0093] Example 7:

[0094] This embodiment provides a window milling machine for machining ball cage cages, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0095] The base 50 has an air chamber 55 and an equipment chamber 56 inside;

[0096] The second driving component 53 includes a piston 530 slidably connected in the cylinder, a piston rod 531 axially connected to the piston 530, and a driving device for driving the piston 530 to slide along the cylinder.

[0097] Among them, the piston rod 531 extends out of the base 50 and is connected to the clamping plate 52 bearing;

[0098] Meanwhile, the piston 530 and the piston rod 531 can be connected by bolts.

[0099] As can be seen from this embodiment, by opening an air chamber 55 and an equipment chamber 56 in the base 50, it is convenient to move the clamping plate 52 by pushing the piston 530 with compressed gas, which has the effects of fast response, simplified structure and easy control and adjustment.

[0100] Furthermore, the piston rod 531 is connected to the clamping plate 52 by bearings, so that when the main shaft mechanism 3 rotates, the clamping plate 52 rotates accordingly, without causing the piston rod 531 and piston 530 to rotate.

[0101] Example 8:

[0102] This embodiment provides a window milling machine for machining ball cage cages, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0103] A first air hole 57 and a second air hole 58 are provided between the air chamber 55 and the equipment chamber 56, and the first air hole 57 and the second air hole 58 are respectively located on both sides of the piston 530 in the sliding direction.

[0104] The drive unit includes a first air pipe 532, a second air pipe 533, an air storage tank and an air pump for supplying air;

[0105] Both the first air pipe 532 and the second air pipe 533 are equipped with control valves 534 for driving opening and closing.

[0106] Meanwhile, the specific structures of the gas storage tank, gas pump, and control valve 534 are all existing mature technologies, and will not be described in detail here.

[0107] As can be seen from this embodiment, by opening a first air port and a second air port between the cylinder and the equipment cavity 56, and by setting a first air pipe 532 and a second air pipe 533 in the air cavity 55, that is, by setting the first air pipe 532, the second air pipe 533 and the control valve 534 in the equipment cavity 56, it is possible to avoid the impact of splashed coolant on the control valve 534 and the air pipe connection during milling, thus avoiding affecting the service life.
