Description

Technical Field

[0001] The invention relates to the field of grinding and polishing equipment, and in particular to an automatic waxing mechanism. Background Art

[0002] In the field of grinding and polishing, the physical principle is generally used, that is, a polishing wheel is used to polish the parts to make the surface of the polished parts smoother. At the same time, in order to improve the polishing quality of some parts, an important step is waxing. Waxing refers to coating the wax material on the surface of the polishing wheel, and then grinding and polishing the parts with the polishing wheel, so that the polished products are smoother and brighter. Because of the rotation and friction between the polishing wheel and the wax material, the wax material is consumed very quickly. The existing technology generally adopts manual wax delivery. The disadvantage of manual wax delivery is that the strength and contact time of wax delivery are difficult to control, and the amount of wax delivered by manual wax delivery is uneven, which affects the polishing quality; moreover, manual waxing is also dangerous, and due to the high-speed rotation of the polishing wheel, the hand holding the wax material contacts the polishing wheel, which is easy to hurt the hand. Summary of the invention

[0004] To achieve the above object, the present invention provides an automatic waxing mechanism, comprising a telescopic movable part, a fixed support part and a power drive part, wherein the power drive part is used to drive the telescopic movable part to perform linear telescopic motion on the fixed support part, wherein:

[0005] The telescopic movable part comprises an optical axis and a wax mounting bracket, both ends of the optical axis are provided with optical axis fixing seats respectively, the wax mounting bracket is connected to the optical axis fixing seat at one end, the front end of the wax mounting bracket is a cantilever structure and is provided with a fixed axis, a sleeve is installed on the fixed axis through a one-way bearing, the sleeve is used to install wax material, and the wax material follows the sleeve to rotate unidirectionally relative to the fixed axis, and the end surface of the sleeve close to the wax mounting bracket is coaxially connected with a ratchet;

[0006] The fixed support component includes a fixed block and a pawl connected to the fixed block, and a sliding sleeve connected to the optical axis sleeve is installed on the fixed block. When the optical axis slides along the sliding sleeve to one end, the wax on the sleeve is driven to extend forward; when the optical axis slides along the sliding sleeve to the other end, the wax on the sleeve is driven to retract backward; when the wax retracts into place, the wax loading bracket approaches the fixed block, and the pawl touches the teeth of the ratchet wheel and pushes the ratchet wheel to rotate a preset angle, thereby driving the sleeve and the wax to rotate synchronously. The preset angle is 360 degrees divided by the number of teeth of the ratchet wheel, and the rotation direction of the ratchet wheel is consistent with the unidirectional rotation direction of the one-way bearing.

[0007] As a further preferred technical solution of the present invention, the cross section of the sleeve is a regular hexagon, and the center of the wax material has a corresponding regular hexagonal hole that is plug-fitted with the sleeve.

[0008] As a further preferred technical solution of the present invention, there are two one-way bearings sleeved on the fixed shaft, and the two one-way bearings are correspondingly arranged at two ends of the sleeve.

[0009] As a further preferred technical solution of the present invention, a wax cover is provided at one end of the sleeve away from the ratchet, and the wax cover is snap-fitted with the sleeve, so that the wax material installed on the sleeve is clamped between the wax cover and the ratchet.

[0010] As a further preferred technical solution of the present invention, the ratchet consists of a push block and a push pin which are hinged to each other, the push block is fixed to the bottom surface of the fixed block, and the front end of the push pin has a hook head which contacts with the ratchet wheel.

[0014] The automatic waxing mechanism of the present invention can achieve the following beneficial effects by adopting the above technical solution:

[0015] 1) The power drive component can accurately control the advance and retreat of the telescopic movable component, so that the force and time of wax delivery can be accurately controlled to ensure uniform wax delivery;

[0016] 2) A one-way intermittent motion mechanism consisting of a ratchet and a pawl. The pawl pushes the ratchet to make a stepping motion, so that the wax material will rotate a preset angle after each telescopic motion is completed, thereby changing the wax feeding contact part of the wax material, thereby making the wax material consumption uniform.

[0017] 3) A one-way bearing is used to control the rotation direction of the wax material, that is, the wax material can be driven to rotate by the ratchet wheel, but not by the polishing wheel of the external polishing machine, thereby increasing the friction between the wax material and the polishing wheel, so that the wax material can be better coated on the polishing wheel;

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the preferred embodiments are only for the convenience of description, and are not used to limit the scope of the present invention. The change or adjustment of the relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0029] like Figures 1 to 5 As shown, the present invention provides an automatic waxing mechanism, which is used in conjunction with a polishing and grinding device to coat a wax material 16 on a polishing wheel of the polishing and grinding device. The mechanism comprises a telescopic movable part 100, a fixed support part 200 and a power drive part 300. The power drive part 300 is used to drive the telescopic movable part 100 to perform a linear telescopic motion on the fixed support part 200. The wax material 16 is driven by the telescopic movable part 100 to perform a linear reciprocating motion to realize the feeding and withdrawing actions of the wax material 16, wherein:

[0030] The telescopic movable component 100 includes an optical axis 2 and a wax mounting bracket 13. Optical axis fixing seats 1 are respectively provided at both ends of the optical axis 2. The wax mounting bracket 13 is connected to the optical axis fixing seat 1 at one end. The front end of the wax mounting bracket 13 is a cantilever structure and is provided with a fixed axis 14. A sleeve 18 is installed on the fixed axis 14 through a one-way bearing 17. The sleeve 18 is used to install wax material 16, and the wax material 16 rotates unidirectionally relative to the fixed axis 14 following the sleeve 18. The end surface of the sleeve 18 close to the wax mounting bracket is coaxially connected with a ratchet 15.

[0031] The fixed support component 200 includes a fixed block 4 and a pawl 11 connected to the fixed block 4. A sliding sleeve 3 connected to the optical axis 2 is installed on the fixed block 4. When the optical axis 2 slides along the sliding sleeve 3 to one end, the wax material 16 on the sleeve 18 is driven to extend forward; when the optical axis 2 slides along the sliding sleeve 3 to the other end, the wax material 16 on the sleeve 18 is driven to retract backward; when the wax material 16 retracts into place, the wax loading bracket 13 approaches the fixed block 4, the pawl 11 touches the teeth of the ratchet 15, and pushes the ratchet 15 to rotate a preset angle, thereby driving the sleeve 18 and the wax material 16 to rotate synchronously. The preset angle is 360 degrees divided by the number of teeth of the ratchet 15, and the rotation direction of the ratchet 15 is consistent with the unidirectional rotation direction of the one-way bearing 17.

[0032] The automatic waxing mechanism of the present invention is used in conjunction with a grinding and polishing device. The wax material 16 on the telescopic movable part 100 performs a linear motion forward and backward to feed and withdraw the material. When the telescopic movable part 100 drives the wax material 16 to extend forward to a certain position, the wax material 16 contacts the polishing wheel of the grinding and polishing device. The rotating polishing wheel rubs against the wax material 16 to coat the wax on the polishing wheel. The wax material 16 only needs to contact the rotating polishing wheel for a very short time before the wax material 16 needs to be withdrawn. Otherwise, too much wax will be applied, resulting in waste. At this time, the telescopic movable part 100 drives the wax material 16 to return to a certain position and wait for the next feeding.

[0033] During actual use, since the one-way bearing 17 limits the rotation direction of the sleeve 18, and the wax 16 and the sleeve 18 are fixedly installed, under the action of the one-way bearing 17, when the wax 16 contacts the rotating polishing wheel, the polishing wheel will not drive the wax 16 to rotate, thereby increasing the friction between the wax 16 and the polishing wheel, so that the wax 16 can be better coated on the polishing wheel.

[0034] A unidirectional intermittent motion mechanism is composed of a ratchet 15 and a pawl 11. The pawl 11 pushes the ratchet 15 to make a stepping motion, that is, each time the telescopic movable part 100 retracts into place, the pawl 11 pushes the ratchet 15 to rotate once, and the rotation angle is 360 degrees divided by the number of teeth of the ratchet 15. In this way, the wax material 16 that is extended each time rotates a certain angle, so that the contact part of the polishing wheel with the wax material 16 is different each time, thereby making the wax material 16 consumed evenly.

[0035] In a specific implementation, the cross section of the sleeve 18 is a regular hexagon, and the center of the wax material 16 corresponds to a regular hexagonal hole that is plugged into the sleeve 18, so that the wax material 16 will not rotate relative to the sleeve 18 after installation, and the installation of the wax material 16 is convenient.

[0036] In a specific implementation, two one-way bearings 17 are sleeved on the fixed shaft 14 , and the two one-way bearings 17 are correspondingly arranged at both ends of the sleeve 18 . The two one-way bearings 17 make the support more stable.

[0037] In a specific implementation, a wax cover 19 is provided at one end of the sleeve 18 away from the ratchet 15 , and the wax cover 19 is engaged with the sleeve 18 , so that the wax material 16 installed on the sleeve 18 is clamped between the wax cover 19 and the ratchet 15 , thereby fixing the position of the wax material.

[0038] Preferably, the ratchet 11 is composed of a mutually hinged ejector block 10 and an ejector pin 9, the ejector block 10 is fixed to the bottom surface of the fixed block 4, the front end of the ejector pin 9 has a hook head that contacts the ratchet 15, and an elastic member is provided at the hinge of the ejector block 10 and the ejector pin 9 or between the two, and the ejector pin 9 maintains balance under the elastic force of the elastic member. The ratchet 15 contacts the hook head of the ejector pin 9, which causes the ejector pin 9 to rotate slightly around its hinge point; when the ratchet 15 is separated from the ejector pin 9, the ejector pin 9 returns to its original position under the elastic force of the elastic member. The elastic member can be a torsion spring, a tension spring or a spring.

[0039] The fixed support component 200 further includes a connecting frame 7, a fixing block 4 is connected to the bottom surface of one end of the connecting frame 7, and the other end of the connecting frame 7 is used to connect with an external mechanism. Specifically, sensors are provided on the two optical axis fixing seats 1, and a sensing sheet 5 is provided on the connecting frame 7. The sensing sheet 5 is respectively inductively matched with the two sensors to respectively detect the extended position and the retracted position of the telescopic movable component 100.

[0040] In a specific implementation, the power drive component 300 includes a servo motor 6, a spur gear 12 and a rack 8. The rack 8 is arranged in parallel with the optical axis 2. The two ends of the rack 8 are respectively fixedly connected to the two optical axis fixing seats 1. The servo motor 6 is fixed on the connecting frame 7. The spur gear 12 is connected to the output shaft of the servo motor 6 and meshes with the rack 8. The servo motor 6 drives the spur gear 12 to rotate, and the transmission force is transmitted between the spur gear 12 and the rack 8, thereby driving the telescopic movable component 100 to move forward or backward as a whole. The forward or backward position is detected by two sensors respectively, and the servo motor 6 is controlled to stop running when it is in place.

[0041] It should be noted here that the power drive component 300 can also be other transmission methods, such as a cylinder transmission method or a transmission method combining a motor and a screw, etc. The power drive component 300 of the above transmission method can drive the telescopic movable component 100 to perform a linear telescopic motion on the fixed support component 200, thereby realizing the feeding and withdrawing actions of the wax material. The detailed structure will not be described one by one here.

[0042] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to the embodiments without departing from the principles and essence of the present invention. The scope of protection of the present invention is limited only by the appended claims.
