Description

Technical Field

[0001] This invention relates to the field of jade product processing technology, and in particular to a polishing device for jade carving products. Background Technology

[0002] Jade polishing is a crucial step in jade processing, as the surface smoothness and texture directly determine the value of the final product. Currently, traditional polishing methods mainly rely on manual operation, as shown in the attached diagram in the instruction manual. Figure 1 As shown: The specific process is as follows: Sandpaper 1 is glued to the end of a clamping rod 2, and then the clamping rod 2 is fixed on the machine tool spindle 3. By driving it to rotate at high speed, the operator holds the jade workpiece and puts it into contact with the rotating sandpaper 1 for grinding and polishing.

[0003] However, to ensure polishing precision, the sandpaper must remain concentric with the rotating axis; otherwise, severe wobbling will occur during high-speed rotation, affecting not only the polishing quality but also posing a safety hazard. In existing technologies, the solution to this problem typically involves marking concentric circles on the rotating rod, and then the operator manually cuts the sandpaper according to these marks to make it circular and as centered as possible. This process requires a high level of experience and skill from the operator, is inefficient, and makes it difficult to guarantee concentricity with each cut.

[0004] Secondly, to improve the ease of polishing concave and curved areas of jade, operators usually manually flip the edge of the sandpaper backward to form a circular side polishing surface. This flipping and shaping step is also entirely manual, which is not only tedious and time-consuming, but also makes it difficult to maintain a consistent width and tightness of the flip, resulting in an irregular polished surface shape and affecting the stability and consistency of the polishing effect.

[0005] Therefore, in order to effectively improve the ease of operation of sandpaper when polishing jade, we propose a polishing device for jade carving products. Summary of the Invention

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Reference Figure 2-10 As one embodiment of the invention, a polishing device for jade carving products is disclosed. This polishing device is used to solve the shortcomings of the current sandpaper polishing process, which requires manual modification and bending, thereby improving the convenience and efficiency of polishing jade.

[0052] Reference Figure 1 Specifically, the polishing device includes a machine base 1 and a rotating unit 2 mounted on the machine base 1. In this embodiment, the rotating unit 2 is configured as a machine tool shaft driven by a motor, and the output end of the rotating unit 2 is fixedly connected to a polishing part 3.

[0053] Of course, the polishing part 3 described in this embodiment includes a rod and an adhesive plate formed at the end of the rod. Sandpaper is adhered to the end face of the adhesive plate. The rod is fixedly connected to the machine tool shaft through a chuck. In this way, when the motor drives the machine tool shaft to rotate, it can drive the sandpaper to rotate. The user can then hold the jade stone and attach it to the surface of the sandpaper for polishing. This method is a conventional technique used by those skilled in the art and will not be elaborated on here.

[0054] Among them, a fixed frame 4 is fixedly installed above the machine base 1, a cutting and flanging unit 5 is provided in front of the fixed frame 4, and a driving component 6 is provided on the fixed frame 4 to drive the cutting and flanging unit 5 to move linearly.

[0055] The processing point of the cutting and flanging unit 5 is aligned with the horizontal radial direction of the polished part 3. The processing point mentioned in this invention includes the cutting processing point and the flanging processing point. The specific structure will be described in detail later, and will not be described here.

[0056] Reference Figure 5 In some embodiments, the cutting and flanging unit 5 of the present invention includes;

[0057] The fixed base 51 and two upright plates 52 connected to the front of the fixed base 51 are vertically spaced and fixed to the end face of the fixed base 51.

[0058] A rotating seat 53 is rotatably connected between the ends of the two upright plates 52. The rotating seat 53 has two mounting surfaces 531. A cutting component 54 and a flanging component 55 are respectively mounted on the outer sides of the two mounting surfaces 531. A pushing component 56 for driving the rotating seat 53 to rotate is provided between the two upright plates 52.

[0059] In other words, in this invention, by fixing the cutting component 54 and the flanging component 55 to the mounting surfaces 531 on both sides of the rotating seat 53, the switching between the cutting and flanging work stations can be achieved when the pushing component 56 drives the rotating seat 53 to rotate.

[0060] It should be noted that in this invention, the two mounting surfaces 531 are close to each other and the two mounting surfaces 531 are at a 90-degree angle to each other. After the rotating seat 53 is driven to rotate by the pushing component 56, the workstation cutting can be realized. In the initial state of this invention, the flange component 55 faces the sandpaper side.

[0061] Reference Figure 3 Furthermore, in this embodiment of the invention, the driving element 6 includes;

[0062] An electric actuator 61 is fixedly installed on the fixed frame 4;

[0063] The shaft end of the electric actuator 61 is fixedly connected to the rear side of the fixed base 51, and a guide rod 62 that passes through the fixed frame 4 is also fixedly installed on the rear side of the fixed base 51.

[0064] In this embodiment of the invention, the forward and backward movement of the entire fixed base 51 is controlled by an electric actuator 61. In this embodiment, the guide rod 62 can be configured as two rods, and the guiding stability of the fixed base 51 is ensured.

[0065] Reference Figure 4 In actual operation, the electric actuator 61 pushes the fixed seat 51 toward the polishing part 3. When the fixed seat 51 moves to the predetermined position, the push assembly 56 can be activated. The push assembly 56 drives the rotating seat 53 to rotate, so as to realize the cutting assembly 54 cutting the sandpaper.

[0066] Of course, the driving component 6 described in this invention can also be configured as a ball screw assembly, which can also achieve linear displacement driving of the fixed seat 51. Those skilled in the art can adapt the specific form according to their needs, and no restrictions are imposed here.

[0067] Reference Figure 5 In an optional embodiment, the cutting assembly 54 includes two blades 541 fixedly mounted on a mounting surface 531, with blades 542 rotatably connected to the ends of the blades 541.

[0068] The two blades 542 have their end faces in contact, and the axis of the blade holder 541 is perpendicular to the axis of rotation of the rotating seat 53.

[0069] In other words, in the initial stage of processing, the rotating unit 2 drives the polishing part 3 to rotate at high speed. When the driving part 6 drives the fixed seat 51 to move toward the side of the sandpaper, after it moves into place, the pushing component 56 drives the rotating seat 53 to rotate. At this time, the two blades 542 flip to the outside of the sandpaper. Since the two blades 542 are in contact with each other, when the sandpaper passes through the two blades 542, its outer part can be cut to form a concentric circular structure with the rotating unit 2, avoiding problems such as rotational swaying and uneven polishing effect caused by eccentricity during bonding.

[0070] It should be noted that in this invention, the contact part of the two blades 542 is the cutting point. That is, when the rotating seat 53 rotates, the center point of the blade 542 and the horizontal radius of rotation of the sandpaper coincide. This design is to ensure that the blade 542 cuts the sandpaper from the tangential direction, so as to ensure the stability of the cutting process.

[0071] Reference Figure 6 , Figure 7 In some embodiments, the pushing component 56 of the present invention includes a pushing member 561 located between the two upright plates 52. Optionally, the pushing member 561 of the present invention may also be configured as an electric actuator or a cylinder, which can be adapted by those skilled in the art. The side of the upright plate 52 is provided with a slide rail 521, and the tail end of the pushing member 561 is rotatably connected to a shaft 562 located in the two slide rails 521.

[0072] The shaft end of the pusher 561 is pinned to the lower side of the rotating seat 53. An ear plate 563 is fixedly installed on the inner side of the upright plate 52. A bushing 564 is sleeved on the outer side of the shaft 562. A spring 565 is connected between the bushing 564 and the ear plate 563.

[0073] In other words, in this invention, the rotating seat 53 is driven to rotate and flip by the pusher 561. In the initial state, the shaft 562 is located at the end of the entire slide 521 under the resistance of the spring 565. When cutting is required, the pusher 561 first extends to push the rotating seat 53 to rotate until the two blades 542 cut towards the cutting edge of the sandpaper.

[0074] Furthermore, due to the design of the slide 521 in this invention, the entire pusher 561 also has a forward movement space. The purpose of this structure is to facilitate the subsequent flanging operation, as can be seen in the following description.

[0075] Reference Figure 6 Based on the above embodiments, the flange assembly 55 of the present invention includes:

[0076] Stop bar 551 and abutment bar 552;

[0077] Two guide grooves 532 are provided on the end face of the other mounting surface 531. The stop rod 551 and the abutment rod 552 are slidably connected in the two guide grooves 532 respectively. An escape component 57 is provided between the stop rod 551 and the rotating seat 53, and a moving component 58 is provided between the abutment rod 552 and the rotating seat 53.

[0078] Specifically, the stop bar 551 described in this invention is used to stop the sandpaper on the back side. When the abutment bar 552 moves, it will abut against the sandpaper and adhere to the stop bar 551 to flip. In this way, the flipping operation is achieved through the cooperation of the stop bar 551 and the abutment bar 552 when the sandpaper rotates.

[0079] Reference Figure 6 It should be noted that the stop rod 551 described in this invention has a bend in the middle, and the end faces the abutment rod 552. This bend is designed to avoid the bend of the sandpaper edge. That is, when the abutment rod 552 is against the edge of the sandpaper, its edge can be accommodated inside the entire bend. In addition, the end of the abutment rod 552 described in this invention is located behind the stop rod 551. This ensures that when the abutment rod 552 moves, it can smoothly bring the edge of the sandpaper against the inside of the bend. Considering the grinding force of the sandpaper during rotation, a ball head can be rotatably connected to the ends of both the stop rod 551 and the abutment rod 552 in this invention. The rotatability of the ball head reduces the friction between the ball head and the sandpaper.

[0080] Furthermore, the opposite portions of the ends of the stop bar 551 and the contact bar 552 described in this invention are flanging processing points. As can be seen from the above description, the flanging processing points in this invention also coincide with the horizontal radial direction of the sandpaper, thus ensuring the stability and reliability of the sandpaper flanging operation.

[0081] Reference Figure 8 In some embodiments, the moving component 58 of the present invention includes;

[0082] A central shaft 581 is formed inside the rotating seat 53, and the axis of the central shaft 581 coincides with the rotation axis of the rotating seat 53.

[0083] A first sliding sleeve 582 is slidably connected to the outer side of the central shaft 581. The first sliding sleeve 582 and the abutting rod 552 are fixedly connected. A wedge block 583 is fixedly connected to the outer side of the first sliding sleeve 582. A movable push rod 584 is fixedly installed on the outer side of the bushing 564. The end of the movable push rod 584 abuts against the wedge block 583.

[0084] Reference Figure 9Based on the above embodiments, the escape component 57 of the present invention includes:

[0085] A second sliding sleeve 571 is slidably connected to the outside of the central shaft 581;

[0086] The second sliding sleeve 571 and the stop rod 551 are fixedly connected;

[0087] A first compression spring 585 is placed between the first sliding sleeve 582 and the second sliding sleeve 571, a second compression spring 572 is placed between the second sliding sleeve 571 and the upright plate 52, an escape block 573 is fixedly installed on the outer side of the second sliding sleeve 571, and a locking rod 574 is also fixedly installed on the outer side of the bushing 564.

[0088] Specifically, in this invention, after the cutting operation is completed, the pusher 561 retracts and resets, thereby driving the rotating seat 53 to rotate and reset. At this time, the stop rod 551 and the abutment rod 552 are located on both sides of the sandpaper, and the stop rod 551 contacts the rear of the sandpaper.

[0089] At this time, the pusher 561 can further retract. In order to position the rotating seat 53 in the initial state, the bottom of the upright plate 52 is also fixedly connected with a limiting plate 522 that stops the rotating seat 53.

[0090] Therefore, when the pusher 561 retracts further, the rotating seat 53 cannot continue to rotate because the limiting plate 522 stops the side of the rotating seat 53. At this time, the contraction force in contact with the pusher 561 causes the entire pusher 561 to move forward and compress the spring 565 mentioned above.

[0091] When the pusher 561 moves forward, the bushing 564 at its tail end will drive the moving push rod 584 to move. In this way, the moving push rod 584 drives the wedge block 583 to move the first sliding sleeve 582. Obviously, when the first sliding sleeve 582 moves, it can drive the abutment rod 552 to move linearly to abut against the side of the sandpaper. With the cooperation of the stop rod 551, the high-speed rotating sandpaper can be flipped.

[0092] It should be noted that, since the end of the stop bar 551 is engaged in the flange after the sandpaper is turned upside down, the stop bar 551 and the abutment bar 552 cannot move in a straight line and separate from the sandpaper in this configuration. Otherwise, the end of the stop bar 551 would push the flange back.

[0093] Therefore, in this invention, an escape component 57 is designed for the stop bar 551, which is used to drive the stop bar 551 to move further backward after the flanging is completed, so as to detach it from the sandpaper flanging and thus avoid interference problems.

[0094] Reference Figure 7 Specifically, the escape block 573 in this invention includes an inlet groove 5731, a retraction groove 5732, and an escape groove 5733 formed on its end face;

[0095] The retraction groove 5732 and the inlet groove 5731 have the same depth and are interconnected. The escape groove 5733 is connected to the other side of the retraction groove 5732 and its depth is less than that of the retraction groove 5732. The end of the locking rod 574 is provided with a spring rod 575, which slides against the inlet groove 5731, the retraction groove 5732 and the escape groove 5733.

[0096] Optionally, the locking rod 574 and the moving push rod 584 described in this invention are configured as a U-shaped structure. The spring rod 575 includes a floating rod that is movably inserted into the end of the locking rod 574 by a spring. The elastic movement of the floating rod can meet the different groove depths of the inlet groove 5731, the retraction groove 5732 and the escape groove 5733.

[0097] Reference Figure 8 , Figure 9 , Figure 10 Specifically, the escape action of the stop lever 551 in this invention is described as follows;

[0098] First, after the sandpaper is cut and rounded, the rotating seat 53 is driven to rotate and reset by the pusher 561. At the same time, the pusher 561 further retracts, and through its own movement, it drives the moving push rod 584 to move outward.

[0099] When the moving push rod 584 moves forward, its end will abut against the wedge block 583, and the movement of the wedge block 583 will drive the first sliding sleeve 582 and the abutting rod 552 to move.

[0100] During this process, the locking rod 574 will also move along with the bushing 564 on the pusher 561. First, the spring rod 575 at the end of the locking rod 574 will be engaged in the guide groove 5731. At this time, the locking rod 574 and the stop of the guide groove 5731 will position the second sliding sleeve 571 to prevent it from moving.

[0101] In the initial stage of flipping, the second sliding sleeve 571 and the stop rod 551 will not move. The first compression spring 585 bears all the compressive force at this time. As the pusher 561 continues to contract, the moving push rod 584 will continuously drive the first sliding sleeve 582 to move, so as to drive the abutment rod 552 to move towards the side of the stop rod 551, thereby achieving the edge flipping of the sandpaper.

[0102] Immediately afterwards, when the pusher 561 retracts and moves further, when the end of the locking rod 574 slides to the back groove 5732, the entire escape block 573 is no longer stopped at the rear stop. Therefore, under the elastic force of the first compression spring 585, the entire escape block 573 also begins to move backward.

[0103] At this time, the second sliding sleeve 571 drives the stop rod 551 to move backward, so that the stop rod 551 can be disengaged from the flange. The driving part 6 begins to move backward and retract, so that the entire cutting flange unit 5 is completely separated from the edge of the sandpaper.

[0104] This action allows for the automatic trimming of the center circle of the sandpaper and the automatic flanging of the edges, thereby improving the ease of operation and reliability during the jade polishing process.

[0105] Of course, after polishing the edge of the sandpaper for a certain period of time, the edge will become ineffective. At this time, the above actions can be repeated to continuously trim and fold the edge of the sandpaper. The operation is convenient and reliable.

[0106] Of course, the lengths of the stop bar 551 and the abutment bar 552 described in this invention can be made of telescopic rods with self-locking structures to achieve adaptive adjustment of their flange length. This method is a conventional approach for those skilled in the art and will not be elaborated upon here.

[0107] In a further embodiment, the first sliding sleeve 582 and the second sliding sleeve 571 are circumferentially locked to the central shaft 581. Specifically, a sliding groove can be formed on the outer side of the central shaft 581, and a protrusion can be formed on the inner side of the first sliding sleeve 582 and the second sliding sleeve 571, so as to ensure that the first sliding sleeve 582 and the second sliding sleeve 571 slide stably on the outer side of the central shaft 581.

[0108] Furthermore, considering the guiding properties of the locking rod 574 and the movable push rod 584, a guide sleeve 59 is fixedly installed on the inner side of the vertical plate 52 to guide the sliding of the locking rod 574 and the movable push rod 584. The guiding constraint of the guide sleeve 59 ensures the smooth movement of the locking rod 574 and the movable push rod 584.

[0109] In summary, the cutting and flanging unit 5 used in this invention can be used to trim, round, and flang the sandpaper in the early stage of jade polishing. The operation is simple and convenient, and can greatly improve work efficiency compared with the manual operation method in transmission technology.

[0110] Secondly, the cutting and flanging unit 5 adopts an integrated rotatable cutting component 54 and flanging component 55, which can automatically switch processing stations during the operation of sandpaper, thus further improving the convenience of operation.

[0111] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
