[0002] As the tasks that space-based robotic arms need to perform become increasingly complex, the types and numbers of end effectors used on these arms are also increasing. For example, cutting tools can be installed at the end of the space-based robotic arm during cutting operations.

[0003] However, traditional cutting tools have the following problems:

[0014] Preferably, the motor assembly includes a motor housing, a motor stator, a motor rotor, a motor shaft, a bearing sleeve, an angular contact bearing, a disc spring washer, a disc spring, a motor end cover, and a motor shaft sleeve.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0031] Specific implementation method one: Combining Figure 1-8 This embodiment describes a buffer-adaptive rotary deep groove cutting tool, which includes an angle-adaptive dust cover 1, a cutter head transmission mechanism 2, a motor assembly 3, and a tool-side quick-change interface assembly 5. The angle-adaptive dust cover 1 is connected to the cutter head transmission mechanism 2, the motor assembly 3 is connected to the cutter head transmission mechanism 2, and the tool-side quick-change interface assembly 5 is connected to the motor assembly 3.

[0032] Specific Implementation Method Two: Combining Figure 1-3This embodiment describes a buffer-adaptive rotary deep groove cutting tool. The angle-adaptive dust cover 1 includes an arc-shaped fixing plate 1-1, a dust cover support plate 1-2, a left dust cover 1-3, a right dust cover 1-4, a spring 1-5, a pin 1-6, and a retaining ring 1-7. The arc-shaped fixing plate 1-1 and the dust cover support plate 1-2 are detachably connected by bolts. The middle part of the dust cover support plate 1-2 is rotatably connected to one end of the left dust cover 1-3 and the right dust cover 1-4 via the pin 1-6. A retaining ring 1-7 is installed at the end of the pin 1-6. The left dust cover 1-5... -3. The middle part of the right dust cover 1-4 is connected to the dust cover support plate 1-2 by springs 1-5. The springs 1-5 are located on both sides of the pin 1-6. The side of the dust cover support plate 1-2 is machined with limiting grooves. The connecting rods at one end of the left dust cover 1-3 and the right dust cover 1-4 pass through the limiting grooves and are rotatably connected to the dust cover support plate 1-2. The left dust cover 1-3 and the right dust cover 1-4 are centered on the pin 1-6 and are limited by contact between the inner wall of the groove and the connecting rods of the two dust covers. The two ends of the springs 1-5 are fixedly installed on the left and right connecting rods and the dust cover support plate 1-2 by bolts.

[0033] Specific implementation method three: Combining Figure 1 Alternatively, 4 describes this embodiment, which is a buffer-adaptive rotary deep groove cutting tool: the other ends of the left dust cover 1-3 and the right dust cover 1-4 are each provided with a cover structure. The cover structure includes a top arc surface 34-1, an upper arc baffle 34-2, an arc flat baffle 34-3, and a lower arc baffle 34-4. The end of the arc flat baffle 34-3 is provided with a top arc surface 34-1. The two sides of the top arc surface 34-1 are provided with an upper arc baffle 34-2 and a lower arc baffle 34-4. The upper arc baffle 34-2 and the lower arc baffle 34-4 are both connected to the arc flat baffle 34-3. The included angle between the upper arc baffle 34-2, the lower arc baffle 34-4 and the arc flat baffle 34-3 is less than 180° and greater than 90°.

[0034] The top arc surface 34-1 is designed in an arc shape. On the one hand, it reduces the contact area and friction with the contacted surface when cutting in the direction perpendicular to the tool. On the other hand, when the cutting plane is uneven or the cutting angle changes, the top arc surface can ensure a larger range of contact positions between the dust cover and the cutting surface, ensuring that the dust cover can be effectively opened at more contact angles. This avoids the problem of the cutting plane pressing the top of the dust cover towards the saw blade axis due to the cutting angle. At the same time, the top arc surface increases the chip blocking range to a certain extent.

[0035] When using a cutting saw blade for grinding, the diamond abrasive grains form a grinding band on the outer edge of the cutting saw blade 2-11. Therefore, the cutting is not only generated from the groove. The upper arc-shaped baffle 1-3-2 of the dust cover effectively blocks the grinding band on the upper surface of the saw blade and the chips and excess material generated by the high-speed grinding and cutting of the groove. The lower arc-shaped baffle 1-3-4 effectively blocks the cutting excess material generated between the lower surface of the saw blade and the surface being cut. The middle connecting arc-shaped plane baffle 1-3-3 blocks the chips between the saw blade and the groove, thus achieving comprehensive shielding of chips from the upper, middle and lower contact surfaces of the saw blade and the groove during grinding and cutting.

[0036] When the cutting tool cuts vertically, the top arc surface 34-1 contacts the plane of the object being cut when a certain cutting depth is reached. During the continuous feeding process, the left dust cover 1-3 and the right dust cover 1-4 maintain contact with the cutting plane through the elasticity of the spring 1-5, ensuring the continuous cutting motion is not hindered and preventing excess material from splashing to the side and rear, which could affect the related parts of the robotic arm. The spring is initially in a stretched state. When the left dust cover 1-3 and the right dust cover 1-4 are rotated around the pin 1-6 under force, the spring 1-5 is further stretched, and the spring force enables the left dust cover 1-3 and the right dust cover 1-4 to automatically reset. When the cutting tool changes the cutting angle, the top arc surface 34-1 contacts the plane being cut, and the spring enables adaptive angle adjustment, preventing chips from splashing to the side and rear while ensuring smooth cutting. Figure 3 The opening and closing capabilities of the adaptive dust cover were demonstrated. The maximum rotation angle of a single dust cover can reach 120° in actual tests. The design avoids the collinearity between the spring and the connecting rods of the dust covers on both sides, as well as the interference between the dust cover and the saw blade. It avoids the configuration where the single dust cover cannot be reset at the maximum opening angle, which can meet most cutting situations and has strong adaptability.

[0037] Specific implementation method four: Combination Figure 1-5This embodiment describes a buffer-adaptive rotary deep groove cutting tool. The cutter head transmission mechanism 2 includes a cutter head housing 2-1, a cutter head housing cover plate 2-2, a motor shaft gear 2-3, a transmission shaft gear 2-4, a torsion spring 2-5, a transmission shaft 2-6, a double-row angular contact ball bearing 2-7, a bearing locking nut 2-8, an outer frame locking nut 2-9, a saw blade mounting plate 2-10, a cutting saw blade 2-11, and a saw blade pressure plate 2-12. The transmission shaft 2-6 is connected to one end of the cutter head housing 2-1 via the double-row angular contact ball bearing 2-7, and the bearing locking nut 2-8 is connected to the transmission shaft 2-1. -6 threaded connection, and the bearing lock nut 2-8 tightens against the inner ring end face of the double row angular contact ball bearing 2-7. The outer frame lock nut 2-9 is threadedly connected to the cutter head housing 2-1, and the outer frame lock nut 2-9 tightens against the outer ring end face of the double row angular contact ball bearing 2-7. The upper end face of the saw blade mounting plate 2-10 abuts against the shoulder of the drive shaft. The inner hole of the boss of the saw blade mounting plate 2-10 is square, which cooperates with the square shaft section of the transmission shaft 2-6 to transmit torque. One end of the transmission shaft 2-6 passes through the saw blade mounting plate 2-10 and extends out of the cutter head housing 2-1. The other end of the transmission shaft 2-6 passes through the saw blade mounting plate 2-10 and connects with the cutting saw blade 2-1. 11. Internal connection: One end of the drive shaft 2-6 is threadedly connected to the inner hole of the saw blade pressure plate 2-12. The cutting saw blade 2-11 is clamped and installed by the saw blade mounting plate 2-10 and the saw blade pressure plate 2-12. The saw blade mounting plate 2-10 is in contact with the surface of the cutting saw blade 2-11. The other end of the drive shaft 2-6 is equipped with a drive shaft gear 2-4. The two ends of the torsion spring 2-5 are connected to the drive shaft 2-6 and the drive shaft gear 2-4 respectively. The drive shaft gear 2-4 is meshed with the motor shaft gear 2-3. The other end of the cutter head housing 2-1 is detachably connected to the cutter head housing cover plate 2-2 by bolts. Arc-shaped fixing plate 1- 1. A through hole is provided between the dust cover support plate 1-2 and the outer wall of one end of the cutter head housing 2-1. One end of the cutter head housing 2-1 is set in the through hole. The cutter head housing 2-1 is connected to the angle adaptive dust cover 1. The cover structure is located outside the cutting saw blade 2-11. The dust cover support plate 1-2 is installed on one side of the cutter head housing 2-1, and the arc fixing plate 1-1 is installed on the other side of the cutter head housing 2-1. The arc fixing plate 1-1 is connected to the dust cover support plate 1-2 by bolts, so that it is fixed to the cutter head housing 2-1. The dust cover assembly 2 can be removed separately without removing the saw blade 2-11.Torsion spring 2-5 is installed between the shoulders of drive shaft gear 2-4 and drive shaft 2-6. Both ends of torsion spring 2-5 are fixed to drive shaft gear 2-4 and drive shaft 2-6 respectively. Through holes are provided on drive shaft gear 2-4 and drive shaft 2-6, allowing the torsion spring's rotational arm to pass through, thus connecting drive shaft gear 2-4 and drive shaft 2-6. The torsion spring arm is fixed by tightening bolts at the end of the drive shaft, which press against the center of the drive shaft. When motor shaft gear 2-3 transmits torque to drive shaft gear 2-4... The drive shaft gear 2-4 transmits torque to the torsion spring arm connected to the drive shaft at one end via the torsion spring 2-5, thus transferring torque from the drive shaft gear to the drive shaft. This transforms the traditional rigid transmission between the drive gear and drive shaft into a flexible, buffered transmission connected by a torsion spring, providing torsional buckling protection. This effectively prevents the saw blade from jamming or the tool from being damaged due to rigid collisions between the high-speed rotating saw blade and the workpiece. It also effectively prevents the connection stiffness between the robotic arm and the tool end from being affected by rigid contact impact vibrations.

[0038] Specific Implementation Method Five: Combining Figure 1-6This embodiment describes a buffer-adaptive rotary deep groove cutting tool. The motor assembly 3 includes a motor housing 3-1, a motor stator 3-2, a motor rotor 3-3, a motor shaft 3-4, a bearing sleeve 3-5, an angular contact bearing 3-6, a disc spring washer 3-7, a disc spring 3-8, a motor end cover 3-9, and a motor shaft sleeve 3-10.

The inner ring of angular contact bearing 3-6 is connected to the motor shaft 3-4. A motor shaft sleeve 3-10 is installed on the end face of the output end of angular contact bearing 3-6. The motor shaft sleeve 3-10 is mounted on the motor shaft 3-4, and the other end face of the motor shaft sleeve 3-10 contacts the motor shaft gear 2-3. Disc spring washers 3-7 and 3-8 are sequentially installed between the motor end cover 3-9 and the outer ring end face of the angular contact bearing 3-6.

Under the action of the disc spring, cover 3-9 and disc spring washer 3-7 have a temperature difference deformation compensation gap. The bearing end cover and disc spring washer are in a non-contact state. The disc spring preload design at the end of the angular contact bearing near the transmission end of the motor assembly can effectively provide a reserved compression adjustment amount under large temperature difference environment, maintain a suitable preload force between the inner and outer rings of angular contact bearing 3-6, provide a certain compensation gap, prevent angular contact bearing 3-6 from jamming, solve the part matching problem caused by the heat and cold deformation of motor housing and motor shaft components under large temperature difference environment, and ensure normal operation.

The guide pins 5-2 are conical and have locking grooves machined on them, and are fixed to the tool support beam by bolts and washers. The quick-change tolerance guide interface 5-3 is bolted to the bottom of the tool support beam. The conical surface design provides a certain tolerance, allowing the robotic arm to achieve quick-change interface guidance and positioning when control precision requirements are not high. The guide groove further realizes the positioning of the quick-change device at the end of the robotic arm and the quick-change interface on the tool side. Finally, the inner groove of the ball lock on the tool side and the ball lock mechanism in the quick-change interface at the end of the robotic arm work together to lock the tool. The docking process is briefly described below. The robotic arm end is slowly approached to the docking interface on the tool side. The ball lock docking mechanism at the end of the robotic arm first contacts the guide cone surface. The cone surface guides the ball lock mechanism at the end of the robotic arm in the feed state to enter the quick-change tolerance guide interface on the tool side. The guide groove and the quick-change protrusion structure at the end of the robotic arm combine to further guide precisely. When the locking steel ball at the end of the robotic arm enters the inner groove of the ball lock in the quick-change tolerance guide interface, the tool and the end of the robotic arm are locked.
