Description

Technical Field

[0001] This utility model relates to the field of alloy rotary file processing technology, specifically an alloy rotary file grinding device. Background Technology

[0002] High-speed steel rotary files are mainly driven by power tools or pneumatic tools. At present, the production of high-speed steel rotary files mainly involves injecting metal powder into ordinary molds for molding and sintering into file head blanks. Subsequently, the file head blanks are ground to form the file heads. During processing, the file head blanks need to be fixed to ensure the processing accuracy of the file head blanks.

[0003] In response, Chinese patent application number CN202021102419.5 discloses a grinding device for machining high-speed steel rotary files. The device includes a machining platform and multiple support legs mounted on the lower end of the platform. Positioning boxes and a movable frame are respectively located on both sides of the upper end of the machining platform. A positioning mechanism is installed on the side of the positioning box closest to the movable frame. A grinding mechanism is installed on the upper part of the side wall of the movable frame. A displacement mechanism is installed at the lower end of the movable frame through a strip-shaped sliding hole opened in the side wall of the machining platform. The positioning mechanism includes a rear support block inserted into the side wall of the positioning box. This utility model is particularly suitable for grinding high-speed steel rotary files and has high social use value and application prospects.

[0004] This grinding device uses a clamping and positioning block with positioning grooves of different inner diameters to facilitate the positioning of rotary file blanks of different shaft diameters. However, in actual use, as the inner diameter of the positioning groove gradually decreases as it extends towards the rear support block, the smaller the inner diameter of the positioning groove, the deeper it goes into the clamping and positioning block. When processing smaller rotary file blanks, because the length of the rotary file blank is short, it will be completely hidden in the clamping and positioning block after being installed in the positioning groove, and cannot be exposed, thus making grinding impossible.

[0005] Therefore, in order to solve the above problems, an alloy rotary file grinding device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an alloy rotary file grinding device to solve the problem mentioned in the background art. In the prior art, the grinding device is equipped with a clamping and positioning block with positioning grooves of different inner diameters. This allows for convenient positioning of rotary file blanks with different shaft diameters. However, in actual use, as the inner diameter of the positioning groove gradually decreases as it extends towards the rear support block, the smaller the inner diameter of the positioning groove, the deeper it goes into the clamping and positioning block. When processing smaller rotary file blanks, because the length of the rotary file blank is short, it will be completely hidden in the clamping and positioning block after being installed in the positioning groove, and thus cannot be exposed, making grinding impossible.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an alloy rotary file grinding device, comprising: a processing table, an electric push rod and a clamp mounted on the top surface of the processing table, a grinding motor mounted on the extended end of the electric push rod, a grinding head fixedly connected to the output end of the grinding motor, and a workpiece blank clamped on the inner side of the clamp.

[0008] The top surface of the processing table is provided with a hollow groove;

[0009] A positioning structure is installed on the processing table. The positioning structure includes a fixing plate, which is fixedly installed on the top surface of the processing table. A fixing cylinder is fixedly connected to the right side wall of the fixing plate. An inner cylinder is slidably installed on the inner wall of the fixing cylinder. A spring is fixedly connected to the outer wall of the inner cylinder. A cover plate is installed on the inner side of the inner cylinder.

[0010] Preferably, a protective structure is installed on the processing table. The protective structure includes an arc-shaped cover, which is movably installed on the top surface of the processing table via a rotating shaft. A left sealing brush and a right sealing brush are respectively installed on the left and right side walls of the arc-shaped cover. A guide rail is fixedly installed on the bottom surface of the processing table, and a collection box is slidably installed on the inner side of the guide rail.

[0011] Preferably, the clamp and the electric push rod are located on both sides of the empty slot, and the fixing plate is located on the left side of the empty slot.

[0012] Preferably, the inner cylinder and the spring are provided in three sets, the three sets of inner cylinders are slidably sleeved with each other, the end of the spring is fixedly connected to the inner wall of the fixed cylinder and the inner cylinder, and the strength of the three sets of springs increases sequentially from the inside to the outside.

[0013] Preferably, the right side walls of the fixed cylinder, the three sets of inner cylinders, and the baffle are flush.

[0014] Preferably, the arc-shaped cover is located on the rear side of the empty trough, the guide rail is located on the lower side of the empty trough, and the collection box communicates with the interior of the empty trough.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting an inner cylinder that can slide against each other inside the fixed cylinder, this utility model can ensure that the length of the workpiece blank entering the inner side of the fixed cylinder is fixed when fixing workpiece blanks with different shaft diameters, thereby ensuring that the processing section of the workpiece blank can be exposed inside the fixed cylinder for processing, thus improving the user experience of the device.

[0016] 1. This utility model, by setting a positioning structure, inserts the workpiece blank into the fixed cylinder. The workpiece blank will push the inner cylinder whose outer diameter length corresponds to its diameter length. When the inner cylinder moves, it will squeeze the spring on the outer wall, and the inner cylinder including its inner side will move towards the inner side of the fixed cylinder, so that the fixed length on the workpiece blank can be inserted into the fixed cylinder, ensuring that the processed section of the workpiece blank can be exposed. Then, the workpiece blank can be further clamped and fixed by the clamp. The grinding motor and grinding head can be driven to approach the workpiece blank by the electric push rod.

[0017] 2. This utility model, by setting up a protective structure, allows the arc-shaped cover to be pulled to cover the upper side of the empty slot and the workpiece blank. The fixed cylinder can move inside the left sealing brush, and the output end of the grinding motor can move inside the right sealing brush. This ensures the shielding effect of the arc-shaped cover on the empty slot and the workpiece blank. When the grinding motor is started, the workpiece blank can be ground by the grinding head. The generated debris can fall down into the collection box through the empty slot under the shielding of the arc-shaped cover, ensuring safety and reducing pollution to the device. Pulling the collection box can remove the collection box from the guide rail, making it easy to empty the debris from the collection box. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-4 An embodiment of an alloy rotary file grinding device provided by this utility model:

[0025] The processing table 1, slot 11, electric push rod 12, grinding motor 13, grinding head 14, fixture 15 and workpiece blank 16 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0026] An alloy rotary file grinding device includes: a processing table 1, an electric push rod 12 and a clamp 15 mounted on the top surface of the processing table 1, a grinding motor 13 mounted on the extended end of the electric push rod 12, a grinding head 14 fixedly connected to the output end of the grinding motor 13, and a workpiece blank 16 clamped on the inner side of the clamp 15.

[0027] A slot 11 is provided on the top surface of the processing table 1;

[0028] A positioning structure 2 is installed on the processing table 1. The positioning structure 2 includes a fixing plate 21, which is fixedly installed on the top surface of the processing table 1. A fixing cylinder 22 is fixedly connected to the right side wall of the fixing plate 21. An inner cylinder 23 is slidably installed on the inner wall of the fixing cylinder 22. A spring 26 is fixedly connected to the outer wall of the inner cylinder 23. A baffle 27 is installed on the inner side of the inner cylinder 23. By setting an inner cylinder 23 that can slide against each other inside the fixing cylinder 22, when fixing workpiece blanks 16 with different shaft diameters, the length of the workpiece blank 16 entering the inner side of the fixing cylinder 22 can be fixed, thereby ensuring that the processing section of the workpiece blank 16 can be exposed inside the fixing cylinder 22 for processing, thus improving the user experience of the device.

[0029] Furthermore, a protective structure 3 is installed on the processing table 1. The protective structure 3 includes an arc-shaped cover 31, which is movably mounted on the top surface of the processing table 1 via a rotating shaft. A left sealing brush 32 and a right sealing brush 33 are respectively installed on the left and right side walls of the arc-shaped cover 31. A guide rail 34 is fixedly installed on the bottom surface of the processing table 1, and a collection box 35 is slidably installed on the inner side of the guide rail 34. Pulling the arc-shaped cover 31 causes it to cover the upper side of the empty groove 11 and the workpiece blank 16, and the fixed cylinder 22 can move inside the left sealing brush 32. Simultaneously, the output end of the grinding motor 13 can move inside the right sealing brush 33, ensuring the shielding effect of the arc-shaped cover 31 on the slot 11 and the workpiece blank 16. When the grinding motor 13 is started, the workpiece blank 16 can be ground by the grinding head 14, and the generated debris can fall down into the collection box 35 through the slot 11 under the shielding of the arc-shaped cover 31, ensuring safety and reducing pollution to the device. Pulling the collection box 35 can remove the collection box 35 from the guide rail 34, making it easy to pour out the debris in the collection box 35.

[0030] Furthermore, the clamp 15 and the electric push rod 12 are located on both sides of the slot 11, and the fixing plate 21 is located on the left side of the slot 11. The positioning structure 2 can fix the workpiece blank 16 on the left side of the slot 11, so that the processing section of the workpiece blank 16 is located inside the slot 11, which is convenient for the grinding head 14 on the right side of the slot 11 to grind it.

[0031] Furthermore, three sets of inner cylinders 23 and springs 26 are respectively provided. The three sets of inner cylinders 23 are slidably sleeved with each other. The ends of the springs 26 are fixedly connected to the inner walls of the fixed cylinder 22 and the inner cylinder 23. The strength of the three sets of springs 26 increases from the inside to the outside. The springs 26 provide power for the reset of the inner cylinder 23. When the workpiece blank 16 pushes the inner cylinder 23, it can drive the inner cylinder 23 on its inner side to move together. The inner cylinder 23 on the outer side can be kept fixed under the action of the stronger springs 26, so that the insertion length of the workpiece blank 16 inside the fixed cylinder 22 remains fixed.

[0032] Furthermore, the right side walls of the fixed cylinder 22, the three sets of inner cylinders 23, and the baffle 27 are flush, so that debris will not accumulate in the fixed cylinder 22, which can ensure the flexibility of the positioning structure 2.

[0033] Furthermore, the arc-shaped cover 31 is located on the rear side of the empty groove 11, the guide rail 34 is located on the lower side of the empty groove 11, the collection box 35 is connected to the interior of the empty groove 11, the arc-shaped cover 31 can cover the outside of the empty groove 11 and shield the workpiece blank 16 and the grinding head 14, and the chips during processing can be collected in the collection box 35.

[0034] Working principle: Before processing, the workpiece blank 16 is inserted into the fixed cylinder 22. The workpiece blank 16 will push the inner cylinder 23 whose outer diameter length corresponds to its diameter length. When the inner cylinder 23 moves, it will squeeze the spring 26 on the outer wall. The inner cylinder 23, including its inner side, moves towards the inner side of the fixed cylinder 22 so that the fixed length on the workpiece blank 16 can be inserted into the fixed cylinder 22, ensuring that the processing section of the workpiece blank 16 can be exposed. Then, the workpiece blank 16 can be further clamped and fixed by the clamp 15. The grinding motor 13 and the grinding head 14 can be driven to approach the workpiece blank 16 by the electric push rod 12.

[0035] Pulling the arc-shaped cover 31 allows it to cover the upper side of the empty slot 11 and the workpiece blank 16. The fixing cylinder 22 can move inside the left sealing brush 32, and the output end of the grinding motor 13 can move inside the right sealing brush 33. This ensures the shielding effect of the arc-shaped cover 31 on the empty slot 11 and the workpiece blank 16. Starting the grinding motor 13 allows the grinding head 14 to grind the workpiece blank 16. The generated debris can fall down into the collection box 35 through the empty slot 11 under the shielding of the arc-shaped cover 31, ensuring safety and reducing contamination of the device. Pulling the collection box 35 allows it to be removed from the guide rail 34, making it easy to empty the debris from the collection box 35.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
