Technical Field
[0001] The invention belongs to the technical field of grinding processing equipment, and in particular relates to a dinosaur skeleton model grinding processing equipment. Background Art
[0002] Dinosaur culture halls / museums are places where people learn about prehistoric culture. Large dinosaur skeleton models need to be set up in the venues so that people can better understand the physiological structure of dinosaurs and increase people's knowledge of prehistoric creatures. At present, the production of large dinosaur skeleton models is mostly carried out using the following production methods:
[0003] ①Build a three-dimensional model of the dinosaur skeleton and use specific clay materials to make a bone model of the dinosaur skeleton;
[0004] ② After the clay model is made, a plaster outer mold is made, and then fiberglass is brushed on the inside of the outer mold. After it is completely dry, the outer mold is opened and the fiberglass bone model of the dinosaur skeleton is obtained after the mold closing process;
[0005] ③Use grinding tools to process the fiberglass surface of the bone model to remove burrs;
[0006] ④Assemble and color the fiberglass bone model to obtain a dinosaur model skeleton.
[0007] When grinding the surface of fiberglass, due to the different shapes of the bones of dinosaur skeletons, angle grinders (grinding machines) are generally used for grinding when grinding the relatively flat skeleton parts of the dinosaur skeleton (such as the long and flat rib parts). However, when grinding small uneven parts and penetrating parts (such as the spine, head, nose bridge, palm and sole skeletons), the angle grinder cannot directly grind these parts, and it is necessary to replace the grinding equipment and use a longer and smaller diameter grinding rod for grinding. Therefore, there will be inconvenience in the grinding process. For this reason, we propose a dinosaur skeleton model grinding processing equipment. Summary of the invention

[0036] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0037] like Figures 1 to 7 The dinosaur skeleton model grinding and processing equipment shown in the figure includes a driving body 001, a rotating drum 100 and a grinding mechanism. The driving body 001 is equipped with a motor, and the output shaft of the motor is detachably connected to the rotating drum 100. The driving body 001 is used to drive the rotating drum 100 to rotate. The grinding mechanism includes a grinding wheel 110 arranged on the outer wall of the rotating drum 100 and a grinding rod 120 built into the rotating drum 100.
[0038] The rotating drum 100 is coaxially provided with an outer sleeve 111, and the inner wall of the outer sleeve 111 does not contact the outer wall of the rotating drum 100. A fixing plate 112 is fixedly provided on the middle side of the outer wall of the outer sleeve 111. A clamping assembly is provided at one end of the outer sleeve 111 away from the driving body 001. The grinding wheel 110 is clamped and fixed by the clamping assembly and the fixing plate 112. A plug-in assembly is also provided between the outer sleeve 111 and the rotating drum 100. A mounting assembly is slidably connected inside the rotating drum 100, and the mounting assembly is used to connect the grinding rod 120.
[0039] A handle 002 is fixedly provided at one end of the driving body 001 away from the rotating drum 100, a sliding frame 130 is slidably provided on the outer shell of the driving body 001, the sliding frame 130 is provided with a plurality of horizontal bars 131, an annular slide rail 132 is provided on the surface of the fixed plate 112, the annular slide rail 132 is provided with a plurality of sliders 133, each horizontal bar 131 is fixedly connected to each slider 133, the sliding frame 130 is provided with a pulling handle 134, and a rebound component is provided between the pulling handle 134 and the outer shell of the driving body 001;
[0040] A transmission assembly is also provided between the outer sleeve 111 and the mounting assembly, and the outer sleeve 111 and the mounting assembly move in opposite directions through the transmission of the transmission assembly.
[0041] Before use, the grinding wheel 110 is clamped to the outer wall of the outer sleeve 111 by inserting the mounting hole of the grinding wheel 110 into the outer wall of the outer sleeve 111, and the grinding wheel 110 is clamped to the outer wall of the outer sleeve 111 by the cooperation of the clamping assembly and the fixing plate 112. At the same time, the grinding rod 120 is installed with the mounting assembly. In this embodiment, the outer sleeve 111 and the rotating drum 110 are coaxially mounted and the inner wall of the outer sleeve 111 does not contact the outer wall of the rotating drum 100, so that the outer sleeve 111 and the rotating drum 110 are in a state of not contacting each other.
[0042] like Figure 1 , Figure 3 and Figure 4 As shown, when the pulling handle 134 overcomes the elastic force of the rebound assembly and moves close to the grip 002, the clamping assembly drives the grinding wheel 110 to move close to the driving body 001, the plug-in assembly disconnects the outer sleeve 111 from the rotating drum 100, and through the reverse transmission of the transmission assembly, the mounting assembly slides outward relative to the rotating drum 100, so that the grinding rod 120 extends out of the rotating drum 100;
[0043] Specific reference Figure 1 , Figure 3 and Figure 4 To explain, when the pulling handle 134 moves close to the grip 002, the sliding frame 130 is pulled, so that the sliders 133 of each horizontal bar 131 pull the sliders 133, and then the fixed plate 112 of the outer sleeve 111 is pulled to move close to the driving body 001. Since the grinding wheel 110 is clamped on the outer wall of the outer sleeve 111, the grinding wheel 110 will move close to the driving body 001. At this time, the plug-in component disconnects the outer sleeve 111 from the rotating drum 100, and due to the setting of the transmission component, the outer sleeve 111 can move in the opposite direction to the installation component, so that the installation component moves in the direction away from the driving body 001, and the grinding rod 120 installed by the installation component is extended outward relative to the rotating drum 100;
[0044] In this state, when the driving body 001 drives the drum 100 to rotate, since the plug-in assembly between the outer sleeve 111 and the drum 100 is disconnected, and the outer sleeve 111 and the drum 110 are in a non-contacting state, the outer sleeve 111 will not be driven to rotate by the drum 100, so that the grinding wheel 110 will not rotate, and the drum 100 will directly drive the grinding rod 120 installed by the mounting assembly to rotate, and the small area of uneven parts and penetrating parts of the dinosaur skeleton (such as the spine skeleton, the head skeleton, the penetrating position of the nose skeleton, the palm skeleton and the sole skeleton) are polished by the rotating grinding rod 120.
[0045] like Figure 5 , Figure 6 as well as Figure 7 As shown, when the rebound assembly elastically returns to its original position to make the pulling handle 134 away from the grip 002, the plug-in assembly connects the outer sleeve 111 and the rotating drum 100, and pulls the installation assembly into the rotating drum 100 through the pulling mechanism, so that the grinding rod 120 is completely received in the rotating drum 100;
[0046] Specific reference Figure 5 , Figure 6 as well as Figure 7 To explain, when the rebound component elastically returns to its original position to make the pulling handle 134 away from the grip 002, the sliding frame 130 is pushed, so that the sliders 133 of each horizontal bar 131 push the sliders 133, and then the fixed plate 112 of the outer sleeve 111 is pushed to move away from the driving body 001. Since the grinding wheel 110 is clamped on the outer wall of the outer sleeve 111, the grinding wheel 110 moves away from the driving body 001. At this time, the plug-in component will connect the outer sleeve 111 with the rotating drum 100, and due to the setting of the transmission component, the outer sleeve 111 can move in the opposite direction to the installation component, so that the installation component moves in the direction close to the driving body 001, and the grinding rod 120 installed by the installation component is received into the rotating drum 100.
[0047] In this state, when the driving body 001 drives the drum 100 to rotate, since the outer sleeve 111 is connected to the drum 100 through a plug-in assembly, the outer sleeve 111 will rotate synchronously with the rotation of the drum 100, thereby causing the grinding wheel 110 to rotate, and the rotating grinding wheel 110 is used to grind the flatter skeleton parts of the dinosaur skeleton (such as long and flat ribs).
[0048] In this way, the device integrates a grinding wheel and a grinding rod, and can selectively switch the grinding method according to the part of the skeleton. The grinding wheel 110 is used to grind the relatively flat skeleton part, and the grinding rod 120 is used to grind the small area of uneven skeleton and the skeleton part with through holes, thereby overcoming the inconvenience caused by the need to frequently switch different grinding tools during the transmission grinding process.
[0049] As an illustration of the clamping assembly of this embodiment, Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the clamping assembly is a clamping plate 113 threadedly connected to the end of the outer sleeve 111.
[0050] During the installation of the grinding wheel 110, it is only necessary to put the mounting hole of the grinding wheel 110 on the outer sleeve 111, screw in the clamping plate 113, and clamp the fixing plate 112 and the clamping plate 113 on both sides of the grinding wheel 110. The operation is simple and it is also convenient to replace the grinding wheel 110 with different grinding effects.
[0051] As an optimization of this embodiment, Figure 1 , Figure 3 , Figure 5 as well as Figure 6 As shown, the outer shell of the driving body 001 is provided with a plurality of transverse positioning rails 135 , and each transverse bar 131 passes through each transverse positioning rail 135 and is slidably connected to each transverse positioning rail 135 .
[0052] Such an arrangement can position the horizontal bar 131 horizontally through the horizontal positioning rail 135, so that the horizontal sliding of the horizontal bar 131 is more stable.
[0053] As an illustration of the plug-in assembly in this embodiment, Figure 2 As shown in the partial schematic diagram, the plug-in assembly includes a plurality of limit strips 114 evenly arranged on the outer wall of the middle part of the rotating drum 100 and a plurality of insertion strips 115 evenly arranged on the inner wall of the outer sleeve 111. The sides of the limit strips 114 and the insertion strips 115 facing each other are processed into matching wedge-shaped inclined surfaces, and the insertion strips 115 match the gap between two adjacent limit strips 114.
[0054] When the outer sleeve 111 moves away from the driving body 001, the inserting strip 115 of the outer sleeve 111 will gradually move toward the limiting strip 114 of the rotating drum 100. Since the sides of the limiting strip 114 and the inserting strip 115 facing each other are processed into matching wedge-shaped inclined surfaces, and the inserting strip 115 matches the gap between the two adjacent limiting strips 114, and the cross bar 131 is movably connected to the fixed disk 112 of the outer sleeve 111 through the slider 133, when the inserting strip 115 moves toward the limiting strip 114, the fixed disk 112 and the outer sleeve 111 can be guided by the wedge-shaped surface. The sleeve 111 rotates slightly so that the insertion strip 115 is inserted between two adjacent limiting strips 114, so that the outer sleeve 111 and the rotating drum 100 can be connected as one. When the outer sleeve 111 moves close to the driving body 001, the insertion strip 115 of the outer sleeve 111 will be separated from the limiting strip 114 of the rotating drum 100, so that the outer sleeve 111 and the rotating drum 100 can be disconnected. In this way, the connection and disconnection between the outer sleeve 111 and the rotating drum 100 can be achieved, so as to switch the grinding wheel 110 and the grinding rod 120 for grinding.
[0055] As a further explanation of the installation components in this embodiment, Figure 3 , Figure 6 as well as Figure 7As shown, the installation assembly includes a slide 121, a first positioning block 122 is arranged on one side of the slide 121, a first strip positioning groove 123 corresponding to the first positioning block 122 is opened on the inner wall of the rotating drum 100, and one end of the grinding rod 120 is processed into a threaded section and is threadedly installed and fixed to the slide 121.
[0056] The slide 121 is positioned by the cooperation of the first positioning block 122 and the first strip positioning groove 123 on the inner wall of the rotating drum 100. The slide 121 can only slide laterally relative to the rotating drum 100 but will not rotate relative to the rotating drum 100. Therefore, people can screw the threaded section at the end of the grinding rod 120 into the slide 121 for installation. The structure is simple and easy to process.
[0057] As a further description of the rebound component in this embodiment, Figure 1 and Figure 5 As shown, the rebound assembly includes a plurality of spring rods 136 fixedly connected to the outer shell of the driving body 001 , and the movable end of each spring rod 136 is fixedly connected to the sliding frame 130 .
[0058] When the pulling handle 134 pulls the sliding frame 130 to move, the elastic force of the spring rod 136 can enable the pulling handle 134 to be pulled and elastically returned, thereby effectively realizing the back and forth movement and reset of the pulling handle 134 , and the structure is simple and easy to process.
[0059] As a further description of the transmission assembly in this embodiment, Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, the transmission assembly includes an annular frame 140 integrally formed at the end of the outer sleeve 111, an annular slide 141 is arranged inside the annular frame 140, a second strip positioning groove 142 is opened on one side of the outer wall of the rotating drum 100, the annular slide 141 is provided with a second positioning block 143 matching the second strip positioning groove 142, a return spring 144 is arranged between the rotating drum 100 and the slide 121, the slide 121 is provided with a pull wire 145, the pull wire 145 passes through the rotating drum 100 and is fixedly connected to the inner side of the annular slide 141; the outer shell of the driving body 001 is also provided with a transverse bracket 146, and the end of the transverse bracket 146 is provided with a friction block 147 corresponding to the fixed disk 112.
[0060] like Figure 3 and Figure 4As shown, when the pulling handle 134 moves close to the grip 002, at this time, due to the positioning of the second positioning block 143 of the annular slide 141 and the second strip positioning groove 142 on the outer wall of the rotating drum 100, the annular slide 141 can only slide horizontally relative to the rotating drum 100 but cannot rotate relative to the rotating drum 100, and the rectangular frame 140 follows the outer sleeve 110 to move close to the driving body 001, so that the annular slide 141 slides horizontally in the second strip positioning groove 142 close to the driving body 001, and the pull wire 145 is in a wire-releasing state in the rotating drum 100. Under the elastic action of the return spring 144, the grinding rod 120 installed on the slide 121 is pushed out of the rotating drum 100;
[0061] And in this state, the friction block 147 provided on the transverse bracket 146 will abut against the fixed plate 112, and the fixed plate 112 will be fixed and no longer rotate through the action of friction force, thereby making the grinding wheel 110 no longer rotate. In this state, when the rotating drum 100 rotates, since the fixed plate 112 is fixed, the outer sleeve 111 and the rectangular frame 140 fixedly connected to the fixed plate 112 will be fixed, and the rotating drum 100 will drive the annular slide 141 to rotate relative to the rectangular frame 140. At the same time, under the positioning of the first positioning block 122 and the first strip positioning groove 123, the slide 121 will rotate synchronously with the rotating drum 100, and under the positioning of the second positioning block 143 and the second strip positioning groove 142, the annular slide 141 will rotate synchronously with the rotating drum 140. Therefore, the rotations of the slide 121, the rotating drum 100 and the annular slide 141 are synchronous, and when the grinding rod 120 of the slide 121 rotates for grinding, it will not cause the winding and entanglement of the pull line;
[0062] like Figure 6 and Figure 7 As shown, when the rebound assembly elastically returns to its original position to make the pulling handle 134 move away from the grip 002, at this time, the rectangular frame 140 follows the outer sleeve 110 to move away from the driving body 001, so that the annular slide 141 slides laterally in the second strip positioning groove 142 away from the driving body 001, and the pull wire 145 is in a retracted state in the rotating drum 100, thereby overcoming the elastic force of the return spring 144, and the pull wire 145 pulls the grinding rod 120 installed on the slide 121 into the rotating drum 100;
[0063] And in this state, the friction block 147 set on the transverse bracket 146 is disengaged from the abutment against the fixed disk 112, the fixed disk 112 is no longer fixed, and the outer sleeve 111 and the rectangular frame 140 fixedly connected to the fixed disk 112 are also no longer fixed. Therefore, in this state, when the rotating drum 100 rotates, under the connection of the plug-in assembly, the rotating drum 100 will drive the outer sleeve 111, the fixed disk 112, the rectangular frame 140, the clamping disk 113 and the installed grinding wheel 110 to rotate for grinding.
[0064] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
