A grinding device for restoration of cultural relics with a positioning function comprises: a support base 1, a first sleeve 2, a sliding base 3, a clamp mechanism 4, a direction adjustment arm 5, a driving mechanism 6 and a grinding belt 7, wherein the first sleeve 2 is arranged on the top of the support base 1, one end of the sliding base 3 is slidably arranged in the first sleeve 2 along the horizontal direction, the clamp mechanism 4 is arranged at the other end of the sliding base 3, the clamp mechanism 4 is used to clamp the object to be ground, the direction adjustment arm 5 is rotatably arranged on the side wall of the first sleeve 2 close to the clamp mechanism 4, the two ends of the direction adjustment arm 5 are provided with first driven wheels 51, the grinding belt 7 is wound around the outside of the two first driven wheels 51, and the driving mechanism 6 is connected to the first driven wheel 51 in a transmission manner.

[0028] Exemplarily, in the embodiment of the utility model, it also includes a second sleeve 22, a sliding tube 23, a support rod 24, a rotating plate 25, a cylinder 26, a second driven wheel 27, a second locking bolt 53, and a screw 55. The second sleeve 22 is fixedly arranged on the top of the first sleeve 2, and the sliding tube 23 is slidably arranged in the second sleeve 22. The direction adjustment arm 5 is arranged on the side wall of the second sleeve 22 through the second locking bolt 53. An arc groove 54 is provided on the direction adjustment arm 5. The arc groove 54 is arranged with the second locking bolt 53 as the center of the circle. A mounting hole matching the arc groove 54 is provided on the second sleeve 22, and the mounting hole and the arc groove 54 are fixed by screws 55. When the sliding base 3 slides to adjust the position, by setting the second sleeve 22 and the sliding tube 23, the direction adjustment arm 5 can be driven to slide together with the sliding base 3, so that the relative position of the grinding belt 7 and the workpiece to be grinded can be fine-tuned, thereby improving the degree of freedom of the device. Figure 1 As shown, one end of the support rod 24 is fixedly arranged on the top of the second sleeve 22, and the other end is hinged to one end of the rotating plate 25, and the other end of the rotating plate 25 is coaxially fixed to the second driven wheel 27.

When repairing the polished workpiece, the polished workpiece is first fixed on the clamping mechanism, and the driving mechanism is started to drive the first driven wheel 51 to rotate, drive the polishing belt 7 to move, and adjust the position of the sliding base 3 so that the polished workpiece and the polishing belt 7 are in contact with each other for polishing. When it is necessary to adjust the contact angle between the grinding belt 7 and the workpiece to be grinded, first loosen the locking of the direction adjusting arm 5 by the second locking bolt 53, so that the direction adjusting arm 5 can rotate around the second locking bolt 53, and the screw 55 slides on the arc groove 54. When it is adjusted to the required angle, the direction adjusting arm 5 is fixed to the required angle by tightening the second locking bolt 53. At this time, the grinding belt 7 close to the side of the workpiece to be grinded is at the required angle. Since the length of the grinding belt 7 is fixed, after the direction adjusting arm 5 rotates to drive the first driven wheel 51 to rotate, it is necessary to adjust the position of the second transmission chain 52 so that the grinding belt 7 can maintain normal operation. At this time, the support rod 24, the rotating plate 25 and the cylinder 26 cooperate with each other to achieve the purpose.

[0029] The embodiment of the utility model provides a grinding device for cultural relics restoration with a positioning function. A clamp mechanism 4 is provided to fix the object to be polished on a sliding base 3. The sliding base 3 is slidably provided in a first sleeve 2, so that the distance between the object to be polished fixed on the clamp mechanism 4 and the grinding belt 7 can be adjusted, thereby increasing the degree of freedom of the grinding device. A direction adjustment arm 5 is rotatably provided on the side wall of the first sleeve 2, so that the first driven wheel 51 on the direction adjustment arm 5 drives the grinding belt 7 to deform, thereby changing the contact angle between the grinding belt 7 and the object to be polished, thereby further increasing the degree of freedom of the grinding device, and can effectively solve the problem of low degree of freedom and low precision of the cultural relics grinding and restoration device in the prior art.

[0030] Optionally, the clamp mechanism 4 includes a shell 41, a mold base 42, a fixed block 43, a rotating rod 44, a clamping rod 45, a rack rod 46 and a gear 47. The shell 41 is a groove-type structure, the mold base 42 is arranged at the bottom of the groove-type structure, the shell 41 includes two outer side surfaces 411 parallel to each other, one end of the fixed block 43 is fixedly arranged on the outer side surface 411, the middle part of the rotating rod 44 is hinged to the other end of the fixed block 43, one end of the rotating rod 44 is hinged to the clamping rod 45, the other end of the rotating rod 44 is hinged to the rack rod 46, the rack rod 46 is meshed with the gear 47, and the outer side surface 411 is provided with mounting holes matching the clamping rod 45 and the rack rod 46.

Two outer side surfaces 411 parallel to each other are provided with mounting holes. The first rack rod 461 and the second rack rod 462 are respectively meshed with the gear 47 passing through the mounting holes and the interior of the shell 41. The first rack rod 461 is located above the gear 47 and meshes with the gear 47. The second rack rod 462 is located below the gear and meshes with the gear 47. When the gear 47 rotates, it will drive the first rack rod 461 and the second rack rod 462 to move in the horizontal direction. Due to the fixed The block 43 cooperates with the rotating rod 44 to drive the clamping rod 45 to move in the horizontal direction to clamp the workpiece to be polished on the mold base 42. When the gear 47 rotates, since it is desired to control the displacement of the clamping rods 45 located on the two outer sides 411 to be the same, the length of the rotating rods 44 at both ends is the same. Since the second rack rod 462 is located at the bottom, a connecting plate 49 needs to be fixed at the end of the second rack rod 462. One end of the connecting plate 49 is perpendicular to the end of the second rack rod 462, and the other end of the connecting plate 49 is hinged to the rotating rod 44. Through this structure, when the gear 47 rotates, the first rack rod 461 and the second rack rod 462 are displaced by the same distance, and at the same time, the two clamping rods 45 will also be displaced by the same distance to clamp the workpiece to be polished. Through the cooperation of the gear 47 and the rack rod 46, the clamping rod 45 only needs to rotate the gear 47 to clamp and fix the workpiece to be polished. Figure 3 As shown, the mold base 42 has two opposite sloped surfaces, forming a structure with high sides and low middle, so as to facilitate the placement of the polished workpiece on the mold base 42, and the end of the clamping rod 45 also has a sloped surface matching the mold base 42, so that under the joint clamping of the clamping rod 45 and the mold base 42, the polished workpiece can be more firmly fixed on the clamping mechanism, thereby improving the stability of the polishing device for cultural relics restoration.

[0032] Optionally, it also includes a connecting shaft 401, a worm wheel 402, a worm 403 and a rotating handle 404. Two clamp mechanisms 4 are provided.

The worm 403 is meshed with the worm wheel 402. The rotating handle 404 is arranged at the end of the worm 403.

[0033] For example, in the embodiment of the utility model, by providing two clamping mechanisms 4, when processing a relatively long cultural relic, the polished object can be more firmly fixed on the clamping mechanism 4, further improving the stability of the polishing device for cultural relic restoration. By providing a connecting shaft 401, a worm gear 402, a worm 403 and a rotating handle 404, the two clamping mechanisms 4 are connected, and only the rotating handle 404 needs to be operated to simultaneously control the two clamping mechanisms 4 to move and clamp, thereby improving the convenience of operation of the polishing device for cultural relic restoration.

[0034] Optionally, a spring 48 is sleeved on the clamping rod 45 , one end of the spring 48 is fixedly connected to the outer side surface 411 , and the other end is fixedly connected to the front of the hinged end of the clamping rod 45 and the rotating rod 44 .

[0035] For example, in the embodiment of the utility model, by providing the spring 48, a reaction force can be provided when the clamping rod 45 performs a clamping movement, and a certain buffering is performed on the force transmitted by the gear 47, so as to prevent the clamping rod 45 from moving too fast and too large a force when the gear 47 is rotated, thereby preventing the clamping rod 45 from also moving too fast, thereby causing the clamping force on the polished workpiece to be too large and causing the polished workpiece to be damaged. By providing the spring 48, a certain protection can be provided to the polished workpiece, thereby improving the practicality of the polishing device for repairing cultural relics.

[0036] Optionally, the driving mechanism 6 includes a motor 61, a first speed regulating wheel 62, a second speed regulating wheel 63, a transmission belt 64 and a driving wheel 65. The motor 61 is fixedly set on the support base 1, the first speed regulating wheel 62 is set on the motor shaft of the motor 61, the second speed regulating wheel 63 and the driving wheel 65 are coaxially set on the support base 1, the transmission belt 64 is wrapped around the first speed regulating wheel 62 and the second speed regulating wheel 63, and the grinding belt 7 is wrapped around the driving wheel 65.

[0037] For example, in the embodiment of the utility model, by fixing the motor 61 on the support base 1, the device can be made into a whole. When the device needs to be moved or transported, the support base 1 can be directly carried as a whole. Compared with the motor equipment separately provided externally to provide power for the device, the present structure further improves the convenience of operation of the grinding device for cultural relics restoration. By providing the first speed regulating wheel 62 and the second speed regulating wheel 63, the power output by the motor 61 can be adjusted by the diameter ratio of the first speed regulating wheel 62 and the second speed regulating wheel 63 to meet the needs of different processing, thereby further improving the practicality of the grinding device for cultural relics restoration.

[0038] Optionally, a plurality of first speed regulating wheels 62 are provided, and the plurality of first speed regulating wheels 62 are coaxially arranged.

[0039] Illustratively, in the embodiment of the utility model, by setting a plurality of first speed regulating wheels 62, the first speed regulating wheel 62 can be directly replaced according to the power to be transmitted, thereby changing the transmission ratio between the first speed regulating wheel 62 and the second speed regulating wheel 63. When the first speed regulating wheel 62 needs to be replaced, since the plurality of first speed regulating wheels 62 are coaxially arranged, it is only necessary to remove the transmission belt 64 mounted on the first speed regulating wheel 62 and then mount it on another first speed regulating wheel 62. There is no need to disassemble and install the first speed regulating wheel 62. The structure is simple and the operation is convenient, which further improves the operational convenience of the grinding device for cultural relic restoration.

[0040] Optionally, a plurality of second speed regulating wheels 63 are provided, and the plurality of second speed regulating wheels 63 are coaxially arranged.

[0041] Illustratively, in the embodiment of the utility model, by setting a plurality of second speed regulating wheels 63, the second speed regulating wheels 63 can be directly replaced according to the power to be transmitted, thereby changing the transmission ratio between the first speed regulating wheel 62 and the second speed regulating wheel 63. When it is necessary to replace the second speed regulating wheel 63, since the plurality of second speed regulating wheels 63 are coaxially arranged, it is only necessary to remove the transmission belt 64 mounted on the second speed regulating wheel 63 and then mount it on another second speed regulating wheel 63. There is no need to disassemble and install the second speed regulating wheel 63. The structure is simple and the operation is convenient, which further improves the operational convenience of the grinding device for cultural relic restoration.

[0042] Optionally, a first locking bolt 21 is provided on the first sleeve 2 .

[0043] For example, in the embodiment of the utility model, when one end of the sliding base 3 moves to the required position in the first sleeve 2, in order to prevent the polished workpiece from being displaced during the processing, a first locking bolt 21 is provided on the side of the first sleeve 2. By tightening the first locking bolt 21, the sliding base 3 is fixed by the friction force generated by the end of the first locking bolt 21 and the sliding base 3. Alternatively, a plurality of fixing holes matching the first locking bolt 21 may be provided on the sliding base 3. Through the cooperation of the first locking bolt 21 and the fixing holes, the position of the sliding base 3 is fixed, thereby fixing the position of the polished workpiece. This further improves the stability of the polishing device for cultural relic restoration.

At this time, by providing the limit plate 52, a certain supporting force can be provided to the grinding belt 7, so that the grinding belt 7 can be in close contact with the workpiece to be polished, thereby further improving the stability of the grinding device for cultural relic restoration.

[0046] Optionally, a plurality of supporting feet 11 are provided at the bottom of the supporting base 1 .

[0047] For example, in the embodiment of the utility model, a lot of debris or mud will be generated in the process of grinding the workpiece. By providing a plurality of support feet 11 at the bottom of the support base 1, a certain distance is created between the support base 1 and the ground. When cleaning the debris or mud, it is more convenient, and there is no need to move the entire device away to clean the ground. This further improves the ease of operation of the grinding device for cultural relic restoration.
