Description

Technical Field

[0001] This utility model relates to the field of centrifugal grinding machine technology, specifically a centrifugal grinding machine for quick clamping of parts. Background Technology

[0002] A centrifugal grinder is a highly efficient grinding and polishing device. It grinds or polishes samples using grinding media within a high-speed rotating centrifuge drum (or disc). Inside the centrifuge drum, the parts to be ground are positioned and installed, and the high-speed rotating grinding material contacts and rubs against the fixed parts, thus efficiently grinding and polishing their outer surfaces.

[0003] The utility model disclosed in CN205290674U is a high-precision prism centrifugal polishing fixture. It has a simple and practical structure and good stability, laying a good foundation for prism polishing. It can process multiple prisms at one time, and the shapes of the prisms can be different. Moreover, by adjusting the position of the prism disk in the positioning cavity, users can control the angle and surface shape changes of the prism, which greatly improves production efficiency.

[0004] However, the above-mentioned centrifugal grinding and polishing machine with positioning and clamping still has the following problems in actual use: Although the parts are clamped and ground through multiple stations, the clamping mechanism drives the parts to rotate. Parts of different specifications and shapes cannot be guaranteed to be stable when rotating. They are prone to falling off after contacting the grinding material. At the same time, the grinding material cannot continue to contact the parts after centrifugal rotation, which affects the processing efficiency of grinding and polishing.

[0005] Therefore, we propose a centrifugal grinding machine for rapid clamping of parts in order to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a centrifugal grinding machine for quick clamping of parts, in order to solve the problem that existing grinding machines use multiple stations to clamp and grind parts, but such clamping mechanisms drive the parts to rotate, and parts of different specifications and shapes cannot be guaranteed to be stable during rotation. After contact with the grinding material, they are prone to falling off. At the same time, the grinding material cannot continue to contact the parts after centrifugal rotation, thus affecting the grinding and polishing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal grinding machine for quick clamping of parts, comprising a grinding machine body and a protective top cover hinged to the rear of the grinding machine body; further comprising:

[0008] The grinding machine body is provided with a positioning mechanism, which includes a support chassis. A support bracket is fixedly provided on the top surface of the support chassis, and clamping bases are provided at equal intervals on the top surface of the support bracket.

[0009] The grinding machine body is equipped with a re-grinding mechanism, which includes a material collection box. The bottom left and right sides of the material collection box are connected to the inner end of the material collection guide tube.

[0010] Preferably, the positioning mechanism includes a support chassis that is fixedly installed inside the grinding machine body, and a filter material frame is rotatably provided on the outer end of the support chassis, and filter material slots are opened at equal angles on the outer side of the filter material frame.

[0011] Preferably, the positioning mechanism includes a positioning stand, the bottom end of which slides through the interior of the clamping base, and the positioning stands inside the clamping base are connected to each other by abutment springs. The symmetrically arranged positioning stands are used to clamp and position the parts to be ground.

[0012] Preferably, the positioning mechanism includes a drive gear, which is rotatably mounted on the center of the bottom surface inside the grinding machine body via a bearing, and a transmission gear is meshed with the outer side of the drive gear, which is also rotatably mounted on the outer side of the bottom surface inside the grinding machine body via a bearing.

[0013] Preferably, the positioning mechanism includes a drive gear ring, which is fixedly installed on the bottom surface of the filter media frame and meshed with the outside of the transmission gear. The drive gear ring is used to drive the filter media frame and the grinding material inside it to rotate.

[0014] Preferably, the re-grinding mechanism includes a material feeding bracket, which is fixedly installed on the outer side of the bottom surface of the filter material frame, and the outer end of the material feeding bracket slides against the bottom surface of the collection box. The material feeding bracket is used to convey the ground material to the collection conduit outside the collection box.

[0015] Preferably, the re-grinding mechanism includes a circulation conduit, the bottom end of which is rotatably connected to the outer end of the collection conduit, and the top end of the circulation conduit is elastically slidably provided with a docking sleeve, and the bottom end of the docking sleeve is detachably inserted into the interior of the protective top cover. At the same time, the circulation conduit and the docking sleeve are used to re-inject the grinding material into the interior of the filter frame for contact grinding with the parts.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This centrifugal grinding machine for quick clamping of parts uses clamping bases and positioning frames set at equal angles above the supporting chassis to limit and lock the parts. At the same time, the filter frame drives the rotating grinding material into the collection box, and then into the circulation conduit under negative pressure to be reintroduced into the grinding machine body, achieving the effect of circulating material supply for grinding and polishing. The specific details are as follows:

[0017] 1. Pull outwards the positioning brackets that slide symmetrically inside the clamping base, and then place the part between the two positioning brackets. The positioning brackets then slide inwards by the contraction of the anti-spring, so as to clamp the part to achieve positioning and locking, and prevent loosening during subsequent grinding and polishing.

[0018] The rotating drive gear drives the meshing transmission gear, which in turn rotates the drive gear ring and filter media frame that are meshed with the outer wall, so that the abrasive material filled inside the filter media frame comes into contact with the fixedly clamped parts after rotating and is ground and polished.

[0019] 2. The filter media frame drives the material feeding bracket to rotate synchronously, so that the material feeding bracket can move and collect the material inside the collection box and enter the negative pressure collection conduit. At the same time, the collection conduit will transport the grinding material back to the inside of the grinding machine body through the through-connected circulation conduit and docking sleeve, so as to achieve the effect of circulating material supply for grinding and polishing.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 The present invention provides the following technical solution:

[0030] Example 1: To address the problems existing in the actual use of existing clampable centrifugal grinding machines, this example provides a centrifugal grinding machine for quick clamping of parts, comprising a grinding machine body 1 and a protective top cover 2 hinged to the rear of the grinding machine body 1; the grinding machine body 1 is provided with a positioning mechanism, which includes a support base 3, and a support bracket 4 is fixedly provided on the top surface of the support base 3, and clamping bases 5 are provided at equal intervals on the top surface of the support bracket 4; the positioning mechanism includes a positioning stand 10, and the bottom end of the positioning stand 10 slides through the interior of the clamping base 5, and the positioning stands 10 inside the clamping base 5 are interconnected by abutment springs 11, and the symmetrically arranged positioning stands 10 are used to clamp and position the parts to be ground.

[0031] like Figures 6-7 As shown, when the part needs to be ground and polished, the positioning bracket 10, which slides symmetrically inside the clamping base 5, is pulled outwards. Then the part is placed between the two positioning brackets 10. The positioning bracket 10 then slides inwards through the contraction of the abutment spring 11 to clamp the part and lock it in place, preventing it from loosening during the subsequent grinding and polishing process.

[0032] The positioning mechanism includes a support chassis 3 fixedly installed inside the grinding machine body 1, and a filter material frame 8 rotatably mounted on the outer end of the support chassis 3, with filter material slots 9 evenly opened on the outer side of the filter material frame 8; the positioning mechanism includes a drive gear 12, which is rotatably mounted at the center of the bottom surface inside the grinding machine body 1 via a bearing, and a transmission gear 13 is meshed with the outer side of the drive gear 12, which is rotatably mounted on the outer side of the bottom surface inside the grinding machine body 1 via a bearing; the positioning mechanism includes a drive gear ring 14, which is fixedly installed on the bottom surface of the filter material frame 8, and meshes with the outer side of the transmission gear 13, and the drive gear ring 14 is used to drive the filter material frame 8 and the grinding material inside it to rotate.

[0033] like Figures 4-5 As shown, the motor fixedly installed inside the grinding machine body 1 drives the drive gear 12 to rotate, and then the drive gear 12 drives the meshing transmission gear 13 to rotate. The transmission gear 13 then rotates the drive gear ring 14 and the filter frame 8 meshing with the outer wall synchronously, so that the grinding material filled inside the filter frame 8 follows the rotation and comes into contact with the fixedly clamped parts for grinding and polishing.

[0034] Furthermore, the rotating filter media frame 8 causes the grinding material to come into contact with the parts. Under the centrifugal force, some of the grinding material adheres to the inner wall of the filter media frame 8 and is discharged through the filter media slots 9 opened inside the filter media frame 8. Then it is stored and collected through the collection box 6.

[0035] Example 2: To address the problems existing in the practical use of existing clampable centrifugal grinders, this example employs the following technical solution: The grinder body 1 is internally equipped with a re-grinding mechanism, which includes a collection box 6. The bottom left and right sides of the collection box 6 are connected to the inner sides of the collection conduit 7. The re-grinding mechanism includes a material feeding bracket 15, which is fixedly installed on the outer side of the bottom surface of the filter frame 8. The outer end of the material feeding bracket 15 slides against the bottom surface of the collection box 6. The feeding bracket 15 is used to transport the ground material to the collection conduit 7 outside the collection box 6; the re-grinding mechanism includes a circulation conduit 16, and the bottom end of the circulation conduit 16 is rotatably connected to the outer end of the collection conduit 7, and the top end of the circulation conduit 16 is elastically slidably provided with a docking sleeve 17, and the bottom end of the docking sleeve 17 is detachably inserted into the inside of the protective top cover 2. At the same time, the circulation conduit 16 and the docking sleeve 17 are used to put the ground material back into the inside of the filter frame 8 to contact and grind the parts.

[0036] like Figures 2-4As shown, the collection box 6 stores the ejected grinding material, while the filter frame 8 drives the material feeding bracket 15 on the outside of the bottom surface to rotate synchronously, so that the material feeding bracket 15 can move and collect the material inside the collection box 6 and enter the negative pressure collection conduit 7. At the same time, the collection conduit 7 transports the grinding material back to the inside of the grinding machine body 1 through the through-connected circulation conduit 16 and docking sleeve 17, so as to achieve the effect of circulating material supply for grinding and polishing.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
