Description

Technical Field

[0001] The present application belongs to the technical field of mechanical processing equipment, and particularly relates to a deburring device for polishing and grinding cylindrical workpieces. Background Art

[0002] In the machining industry, with the continuous progress of society and the rapid development of science and technology, the market demand for many machined products is increasing, and the requirements are becoming increasingly demanding. Therefore, to meet market demand, it is necessary to ensure product quality while improving production efficiency. Currently, due to the influence of the processing technology, it is difficult to eliminate burrs during the machining process of many products, necessitating a separate deburring process.

[0003] A common deburring method is to use a roller brush machine. This utilizes the machine's high speed, holding the workpiece close to the brush, and adjusting the workpiece's position by moving it left or right or rotating it to polish and remove burrs from the workpiece's surface. This current method requires the operator to hold the workpiece against the rotating force of the roller brush, increasing labor intensity and posing safety risks. Furthermore, different parts of the workpiece are subjected to different forces, resulting in uneven and poorly uniform grinding, impacting the quality of the finished product.

[0004] In addition, in order to prevent over-throwing, burrs cannot be completely removed in a single operation, and the workpiece needs to be inspected and reworked multiple times, which reduces processing efficiency and increases manpower input, resulting in increased production costs. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a deburring device to solve the technical problem that the deburring device in the prior art needs to be clamped manually, resulting in uneven force on the processed parts of the workpiece and affecting the processing quality.

[0006] To achieve the above objectives, the technical solution adopted in this application is to provide a deburring device, comprising:

[0007] A grinding device, including a roller brush for grinding a workpiece;

[0008] The clamping device includes a telescopic top cone and a rotating top cone, wherein the telescopic top cone and the rotating top cone respectively abut against two ends of the workpiece;

[0009] A loading and unloading device, comprising a bracket and a lifting member, wherein the bracket is used to carry a workpiece, and the lifting member lifts the bracket to be placed between the telescopic top cone and the rotating top cone;

[0010] The driving mechanism is used to drive the grinding device and the loading and unloading device to move back and forth with the clamping device as the target point, so that the roller brush and the bracket are moved alternately to between the telescopic top cone and the rotating top cone; the grinding device and the loading and unloading device are both arranged on the driving mechanism, and the roller brush and the bracket are respectively located on both sides of the clamping device.

[0011] The beneficial effect of the deburring equipment provided by the present application is that, compared with the prior art, the deburring equipment of the present application includes a grinding device, a clamping device, a loading and unloading device and a driving mechanism. The loading and unloading device can automatically mount the workpiece on the clamping device, allowing the grinding device to polish and grind the workpiece, thereby deburring the surface of the workpiece.

[0012] On the one hand, the clamping device includes a telescopic top cone and a rotating top cone, which respectively abut and secure the ends of the workpiece, replacing manual clamping. Because the telescopic and rotating top cones only abut the ends of the workpiece, the workpiece is suspended between the telescopic and rotating top cones. This eliminates any obstruction or interference with the workpiece's circumferential surface, allowing the entire circumference of the workpiece to be polished and ground with the roller brush, eliminating safety hazards and reducing labor costs.

[0013] Among them, the rotating top cone can drive the workpiece to rotate, and while maintaining the same contact strength with the roller brush, the processed part of the workpiece can be automatically changed, so that each processed part on the workpiece is subjected to uniform force, so that the polishing and grinding processing standards of the workpiece surface are consistent, thereby improving the quality of the finished product.

[0014] The loading and unloading mechanism, meanwhile, includes a bracket and a lifting member. The lifting member lifts the bracket to position the workpiece on the bracket at the clamping height between the telescopic and rotating top cones. The telescopic top cone's telescopic function allows it to translate toward the rotating top cone, simultaneously abutting both ends of the workpiece with the rotating top cone, thereby achieving automatic loading.

[0015] Therefore, the overall structure of the deburring equipment of the present application is simple and compact, and occupies a small space. The driving mechanism is used to drive the grinding device and the loading and unloading device to move back and forth with the clamping device as the target point, so as to realize the loading, grinding and unloading operations of the workpiece. The displacement stroke is short, which is conducive to speeding up the production rhythm and improving production efficiency; and the roller brush and the bracket maintain a set distance and do not interfere with each other, effectively ensuring the stability and safety of the processing process.

[0016] The coordination structure between the bracket and the lifting member is improved. The bracket includes a lifting frame and a base plate. The base plate is provided with guide columns. The lifting frame is mounted on the guide columns and can move up and down along the guide columns. The lifting member includes an insert plate and a base plate. The base plate and the base plate are connected by a telescopic assembly. The insert plate is provided on the base plate, and the insert plate has an insertion end for inserting into the bottom of the lifting frame to lift the lifting frame. In this way, combined with the reciprocating movement of the loading and unloading device and the grinding device by the driving mechanism, during the process of automatic loading and grinding, the workpiece can be placed at the clamping height between the telescopic top cone and the rotating top cone by utilizing the coordination between the bracket and the lifting member, and then removed so that the workpiece can be suspended between the telescopic top cone and the rotating top cone to avoid interference with the processing of the workpiece. This is beneficial for the rotating top cone to drive the workpiece to rotate to automatically change the processed part on the workpiece, effectively ensuring the processing uniformity of the processed part. In addition, during the process from grinding to automatic unloading, the bracket and the jacking parts are also used to enable the lifting frame to support the processed finished product for unloading operations, so that the finished product is away from the processing position, so that the finished product can be removed and replaced with a new workpiece, effectively replacing manual clamping and loading and unloading operations, thereby reducing labor costs and improving production efficiency.

[0017] In one embodiment, the telescopic assembly includes a connecting shaft and an elastic member, wherein the connecting shaft is connected between the bottom plate and the base plate; the elastic member is sleeved on the connecting shaft, and the two ends of the elastic member are respectively against the base plate and the bottom plate. The elastic member can preferably be a spring, and the spring is sleeved on the connecting shaft. In this way, the telescopic performance of the elastic member is utilized to enable the jacking member and the lifting frame to be movably connected, thereby driving the plug-in plate to automatically insert into or automatically move away from the bottom of the lifting frame, so that the lifting frame can realize the automatic lifting function. It can be seen that the lifting frame realizes the lifting function by utilizing a simple plug-in structure, which has a simple structure and is easy to implement. It also saves space for setting up a lifting drive mechanism at the bottom of the lifting frame, effectively improving the compactness of each component in the equipment and helping to reduce the volume of the entire machine.

[0018] In one embodiment, the lifting frame includes a support ear and a support column connected to one side of the support ear and extending downward. The support ear has a positioning groove for inserting a workpiece; the support column has a sleeve hole, and the support column is connected to the guide column via the sleeve hole. The guide column serves both to guide and support the support column, thereby defining the displacement path of the lifting frame. The support ear supports the workpiece at the clamping height between the telescopic top cone and the rotating top cone, and the workpiece is positioned using the positioning groove on the support ear. In this way, the positioning groove on the support ear and the support column, guided by the guide column, facilitate the coaxial alignment of the telescopic top cone, the workpiece, and the rotating top cone. The telescopic top cone and the rotating top cone can accurately contact the center points of the two ends of the workpiece, thereby improving the uniformity of the workpiece rotation driven by the rotating top cone to adjust the position of the processed part, ensuring that the surface of the workpiece is polished evenly, effectively improving the quality of the finished product.

[0019] In one embodiment, the insertion end of the insert plate has an inclined surface; the bottom of the lifting frame has a chamfer, and the chamfer cooperates with the shape of the inclined surface to facilitate the insertion end of the insert plate to automatically slide between the bottom of the lifting frame and the upper surface of the base plate, and synchronously lift the lifting frame during the movement of the loading and unloading device.

[0020] The structure of the clamping device has been improved. The clamping device also includes a push-up cylinder, a rotary motor, and a stop plate. The push-up cylinder and the rotary motor are positioned opposite each other at the ends of the stop plate. The telescopic cone is positioned at the output end of the push-up cylinder, and the rotating cone is positioned at the output end of the rotary motor. The telescopic cone and the rotating cone are coaxially aligned to ensure that both the telescopic cone and the rotating cone abut the center points at both ends of the workpiece. In this way, the rotating cone is driven by the rotary motor to rotate, automatically changing the workpiece's circumferential surface to be processed. The push-up cylinder drives the telescopic cone toward the rotating cone, abutting only the ends of the telescopic and rotating cones to suspend the workpiece above the working position of the roller brush. This effectively replaces manual operation and avoids obstruction of the workpiece's circumferential surface that can occur during manual operation. This allows the entire circumference of the workpiece to contact the roller brush for polishing and grinding, thereby improving the quality of the finished product.

[0021] In one embodiment, the clamping device further includes a screw mechanism, which includes a screw body, a movable block, and a drive motor that drives the screw body to rotate. The movable block is connected to the limit plate and is mounted on the screw body. The movable block can drive the limit plate to move along the screw body, thereby driving the limit plate and the telescopic top cone and the rotating top cone on the limit plate to move. In this way, the position of the clamping area between the telescopic top cone and the rotating top cone can be adjusted using the screw mechanism, which can not only improve the positional adaptability between the clamping device and the loading and unloading device, but also improve the applicability to the specifications of the workpiece being processed.

[0022] The structure of the drive mechanism has been improved. The drive mechanism includes a first slider, a second slider, a slide rail, and a linear cylinder. The first and second sliders are both mounted on the slide rail. The loading and unloading device is mounted on the first slider, and the polishing device is connected to the output end of the linear cylinder. A slide is provided at the bottom of the polishing device, which is fixed to the second slider via the slide. The slide is connected to the loading and unloading device via a connector. Thus, the polishing device and the loading and unloading device are both fixed to the sliders of the slide rail and connected together by a connector. When the linear cylinder drives the polishing device to move, it also drives the loading and unloading device to move, allowing both to move along the slide rail, thereby achieving synchronized reciprocating movement of the loading and unloading device and the polishing device.

[0023] In one embodiment, the clamping device further includes a base for supporting the telescopic top cone and the rotating top cone. The base is disposed between the first and second sliders, and the bottom of the base has grooves for engaging the slide rails and the connector, respectively. In this manner, the grooves on the bottom of the base are cleverly utilized to respectively circumvent the slide rails and connectors of the drive mechanism, allowing both to be inserted into the clamping device. This helps prevent interference when the drive mechanism drives the loading and unloading device and the grinding device to synchronously reciprocate, effectively improving the compactness of the various components in the device.

[0024] The structure of the grinding device has been improved. The grinding device includes a driver, a transmission assembly, and a speed regulator. The transmission assembly includes a drive wheel, a driven wheel, and a transmission belt, and the transmission belt is mounted on the drive wheel and the driven wheel. The driver is positioned adjacent to the roller brush, and the output end of the driver is connected to the drive wheel. The speed regulator is drivingly connected between the driven wheel and the roller brush. This allows for a compact placement of the driver and roller brush, and the speed regulator is used to adjust the roller brush's rotational speed, thereby improving the adjustable performance of the grinding device.

[0051] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0052] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0053] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0055] The traditional deburring method is to use a roller brush machine, let the roller brush on the roller brush machine run at high speed, hold the workpiece close to the roller brush, move the workpiece left or right or rotate it to adjust the workpiece's processing posture, and then polish and grind off the burrs on the workpiece surface. Figure 1 For the cylindrical workpiece 100 shown, the operator needs to hold both ends of the workpiece 100 and allow the structure on the circumferential surface of the workpiece 100 to contact the roller brush of the roller brush machine for polishing.

[0056] The applicant discovered that, in actual application, on the one hand, the operator's handheld workpiece 100 is pressed against the rotating force of the roller brush, which increases the operator's labor intensity. The area where the operator's fingers can grip the workpiece 100 is very small, and the fingers are easily exposed to and blocked by the outer peripheral surface of the workpiece 100 near both ends. In fact, the outer peripheral surface of the workpiece 100 is exactly the part that needs to be deburred and is easily blocked by the human hand. At this time, the operator needs to adjust the gripping posture before polishing, which increases the difficulty of gripping the workpiece. It can be seen that the entire polishing and grinding process is very cumbersome, easy to get injured, and poses a safety hazard.

[0057] On the other hand, during the processing, the processed part of the workpiece 100 needs to be manually changed, and the rotation force of the roller brush also changes after the change, resulting in uneven force on the polished parts of the workpiece 100 and poor uniformity, which affects the quality of the finished product.

[0058] In order to prevent over-throwing, the burrs cannot be completely removed in a single operation, and the workpiece 100 needs to be inspected and reworked multiple times, which reduces processing efficiency and increases manpower input, resulting in increased production costs.

[0059] In response to the above situation, the applicant has conducted painstaking research and designed a device for polishing and grinding cylindrical workpieces 100, breaking the inherent thinking of industry professionals (the inherent thinking refers to the traditional method of manually operating the workpiece 100 to deburr) and creatively proposed a new type of deburring equipment, which effectively solves the problem that the existing manual clamping is required, resulting in uneven force on the processed parts of the workpiece 100, affecting the processing quality. It is now described in detail.

[0060] Please also refer to Figure 2 and Figure 3 The deburring equipment includes a grinding device 1, a clamping device 2, a loading and unloading device 3 and a driving mechanism 4.

[0061] The grinding device 1 includes a roller brush 11 for grinding the workpiece 100 . The roller brush 11 can contact the workpiece 100 and polish the contact portion of the workpiece 100 .

[0062] Please also refer to Figure 2 、 Figure 4 and Figure 5 The clamping device 2 includes a telescopic top cone 21 and a rotating top cone 22. The telescopic top cone 21 can be extended toward the rotating top cone 22 so that the telescopic top cone 21 and the rotating top cone 22 respectively abut against the two ends of the workpiece 100. The rotating top cone 22 is used to drive the workpiece 100 to rotate, thereby automatically changing the processing part on the circumference of the workpiece 100.

[0063] Please also refer to Figure 2 、 Figure 6 and Figure 7 The loading and unloading device 3 includes a bracket 31 and a lifting member 32. The bracket 31 is used to carry the workpiece 100. The lifting member 32 lifts the bracket 31 to be placed between the telescopic top cone 21 and the rotating top cone 22, so that the telescopic top cone 21 and the rotating top cone 22 can smoothly press against the two ends of the workpiece 100.

[0064] When the bracket 31 is not lifted by the lifting member 32, it can automatically descend to support the workpiece 100 to complete the unloading operation; or, when the workpiece 100 is clamped by the telescopic top cone 21 and the rotating top cone 22, it can be moved away to avoid interference with the workpiece 100 when it is polished by the roller brush 11.

[0065] The grinding device 1 and loading and unloading device 3 are both mounted on a drive mechanism 4, with the roller brush 11 and bracket 31 located on either side of the clamping device 2. The drive mechanism 4 drives the grinding device 1 and loading and unloading device 3 to reciprocate with the clamping device 2 as the target point, causing the roller brush 11 and bracket 31 to move alternately between the telescopic top cone 21 and the rotating top cone 22.

[0066] Compared with the prior art, the deburring equipment provided in the embodiment of the present application includes a grinding device 1, a clamping device 2, a loading and unloading device 3 and a driving mechanism 4. The loading and unloading device 3 can automatically mount the workpiece 100 on the clamping device 2, allowing the grinding device 1 to polish and grind the workpiece 100, thereby deburring the surface of the workpiece 100.

[0067] On the one hand, the clamping device 2 includes a telescopic top cone 21 and a rotating top cone 22, which respectively abut and fix the two ends of the workpiece 100, replacing the manual clamping of the workpiece 100. Because the telescopic top cone 21 and the rotating top cone 22 only abut the two ends of the workpiece 100, so that the workpiece 100 is suspended between the telescopic top cone 21 and the rotating top cone 22, there is no obstruction or interference on the circumferential surface of the workpiece 100. The circumferential surface of the workpiece 100 can contact the roller brush 11 for polishing and grinding, eliminating safety hazards and reducing labor costs.

[0068] Among them, the rotating top cone 22 can drive the workpiece 100 to rotate, and while maintaining the same strength of contact with the roller brush 11, the processed part of the workpiece 100 can be automatically changed, so that each processed part on the workpiece 100 is subjected to uniform force, so that the polishing and grinding processing standards of the surface of the workpiece 100 are consistent, thereby improving the quality of the finished product.

[0069] The loading and unloading device 3 includes a bracket 31 and a lifting member 32. The lifting member 32 can lift the bracket 31 to place the workpiece 100 on the bracket 31 at the clamping height between the telescopic top cone 21 and the rotating top cone 22. The telescopic top cone 21 can be extended and retracted to allow the telescopic top cone 21 to translate toward the rotating top cone 22, thereby simultaneously abutting against both ends of the workpiece 100 with the rotating top cone 22, thereby achieving automatic loading.

[0070] Among them, the driving mechanism 4 drives the grinding device 1 and the loading and unloading device 3 to move back and forth with the clamping device 2 as the center, so that the roller brush 11 and the bracket 31 can move alternately between the telescopic top cone 21 and the rotating top cone 22, and combined with the lifting member 32 to support or withdraw the bracket 31, the bracket 31 can be automatically raised and lowered, thereby realizing the automated processing of loading, grinding and unloading.

[0071] Specifically, please combine Figures 2 to 7As shown, when the bracket 31 moves between the telescopic top cone 21 and the rotating top cone 22, the loading operation is performed, and at this time the roller brush 11 is away from the clamping device 2; when the roller brush 11 moves between the telescopic top cone 21 and the rotating top cone 22, the roller brush 11 grinds the workpiece 100 clamped between the telescopic top cone 21 and the rotating top cone 22, and the bracket 31 leaves from between the telescopic top cone 21 and the rotating top cone 22 to avoid interference with the processing.

[0072] When the processing is completed, the driving mechanism 4 drives the grinding device 1 and the loading and unloading device 3 to move back and forth, first allowing the roller brush 11 to move away from between the telescopic top cone 21 and the rotating top cone 22, while allowing the bracket 31 to be located between the telescopic top cone 21 and the rotating top cone 22 to support the finished product for unloading operations; and then during the last movement, the bracket 31 carries the finished product away from the clamping device 2, making it convenient to remove the finished product from the bracket 31 and replace it with a new workpiece 100.

[0073] As a result, the overall structure of the deburring equipment of the present application is simple and compact, and occupies a small space. The driving mechanism 4 is used to drive the grinding device 1 and the loading and unloading device 3 to move back and forth with the clamping device 2 as the target point, so as to realize the loading, grinding and unloading operations of the workpiece 100. The displacement stroke is short, which is conducive to speeding up the production rhythm and improving production efficiency; and the roller brush 11 and the bracket 31 maintain a set distance and do not interfere with each other, effectively ensuring the stability and safety of the processing process.

[0074] For the deburring device of the present application, it is particularly important how the loading and unloading device 3 realizes automatic loading or unloading operation in the process of the driving mechanism 4 driving the grinding device 1 and the loading and unloading device 3 to move back and forth. Figure 8 、 Figure 9 and Figure 10 The bracket 31 includes a lifting frame 311 and a bottom plate 312. The lifting frame 311 is used to support the workpiece 100. A guide column 313 is provided on the bottom plate 312. The lifting frame 311 is installed on the guide column 313 and can move up and down along the guide column 313.

[0075] The lifting member 32 includes an insert plate 321 and a base plate 322. The base plate 322 is connected to the bottom plate 312 via a telescoping assembly 33. The insert plate 321 is mounted on the base plate 322 and has an insertion end 323 for inserting into the bottom of the lifting frame 311. When the insertion end 323 of the insert plate 321 is inserted into the bottom of the lifting frame 311, the lifting frame 311 can be lifted.

[0076] In this way, combined with the reciprocating movement of the loading and unloading device 3 and the grinding device 1 by the driving mechanism 4, when the loading and unloading device 3 moves toward the clamping device 2, the insertion end 323 of the insert plate 321 is also automatically inserted into the bottom of the lifting frame 311 to lift the lifting frame 311, so that the lifting frame 311 supports the workpiece 100 and places it at the clamping height between the telescopic top cone 21 and the rotating top cone 22, thereby realizing automatic loading.

[0077] Please also refer to Figure 11 and Figure 12 When the loading and unloading device 3 is removed from the clamping device 2, the insertion end 323 on the insert plate 321 is also automatically removed from the bottom of the lifting frame 311, causing the lifting frame 311 to automatically descend and move away. When the workpiece 100 has been clamped by the telescopic top cone 21 and the rotating top cone 22, it moves away from under the workpiece 100, avoiding interference with the processing of the workpiece 100, allowing the grinding device 1 to polish and grind the workpiece 100.

[0078] After processing is completed, the drive mechanism 4 moves the grinding device 1 away from the clamping device and simultaneously moves the loading and unloading device 3 toward the clamping device 2. The insertion end 323 of the insert plate 321 automatically inserts into the bottom of the lifting frame 311, lifting the lifting frame 311 so that the lifting frame 311 supports the finished product. At this time, the telescopic top cone 21 and the rotating top cone 22 can release the workpiece 100. Specifically, the telescopic top cone 21 and the rotating top cone 22 release their support on both ends of the workpiece 100, allowing the finished product to be supported by the lifting frame 311.

[0079] Then, when the loading and unloading device 3 is removed from the clamping device 2, the insertion end 323 on the inserting plate 321 is automatically removed from the bottom of the lifting frame 311, so that the lifting frame 311 automatically descends while supporting the finished product, thereby realizing the unloading operation.

[0080] It can be seen that the deburring equipment of the present application, during the process from automatic loading to grinding, utilizes the cooperation between the bracket 31 and the lifting member 32 to place the workpiece 100 at the clamping height between the telescopic top cone 21 and the rotating top cone 22, and then removes it so that the workpiece 100 can be suspended between the telescopic top cone 21 and the rotating top cone 22, avoiding interference with the processing of the workpiece 100. This is conducive to the rotating top cone 22 driving the workpiece 100 to rotate to automatically change the processed part of the workpiece 100, effectively ensuring the processing uniformity of the processed parts of the workpiece 100. In addition, during the process from grinding to automatic unloading, the cooperation between the bracket 31 and the lifting member 32 is also utilized to enable the lifting frame 311 to support the processed finished product for unloading operations, moving the finished product away from the processing position so that the finished product can be removed and replaced with a new workpiece 100, effectively replacing manual clamping and loading and unloading operations, thereby reducing labor costs and improving production efficiency.

[0081] Please also refer to Figure 8 、 Figure 11 and Figure 12 The telescopic assembly 33 includes a connecting shaft 331 and an elastic member 332. The connecting shaft 331 is connected between the bottom plate 312 and the base plate 322. The elastic member 332 is mounted on the connecting shaft 331, and the two ends of the elastic member 332 respectively abut against the base plate 322 and the bottom plate 312. The elastic member 332 can preferably be a spring, which is mounted on the connecting shaft 331 to achieve telescopic deformation. In this way, the elastic property of the elastic member 332 is utilized to enable the lifting member 32 to be flexibly connected to the lifting frame 311, thereby driving the plug plate 321 to automatically insert into or automatically move away from the bottom of the lifting frame 311, so that the lifting frame 311 can achieve an automatic lifting function. It can be seen that the lifting frame 311 can achieve the lifting function by using a simple plug-in structure. The structure is simple and easy to implement. It also saves space for setting the lifting drive mechanism 4 at the bottom of the lifting frame 311, effectively improving the compactness of each component in the equipment and helping to reduce the size of the entire machine.

[0082] In this embodiment, please refer to Figure 8 and Figure 10 The lifting frame 311 includes a support ear 3111 and a support column 3112 connected to one side of the support ear 3111 and extending downward. The support ear 3111 has a positioning groove 3113 for the workpiece 100 to be inserted into. The support ear 3111 supports the workpiece 100 at the clamping height between the telescopic top cone 21 and the rotating top cone 22, and the positioning groove 3113 on the support ear 3111 is used to position the workpiece 100.

[0083] The pillar 3112 has a sleeve hole 3114, and the pillar 3112 is sleeved on the guide pillar 313 through the sleeve hole 3114. The guide pillar 313 not only guides the pillar 3112, but also supports the pillar 3112, thereby limiting the displacement path of the lifting frame 311.

[0084] In this way, the positioning groove 3113 on the support ear 3111 and the support column 3112 cooperate with the guidance of the guide column 313, which is conducive to coaxial alignment of the telescopic top cone 21, the workpiece 100 and the rotating top cone 22, so that the telescopic top cone 21 and the rotating top cone 22 can accurately abut the center points of the two ends of the workpiece 100, thereby improving the uniformity of the position of the processed part when the rotating top cone 22 drives the workpiece 100 to rotate, so that the surface of the workpiece 100 is evenly polished, and the quality of the finished product is effectively improved.

[0085] In the embodiments of this application, please refer to Figure 9 and Figure 10The insertion end 323 of the inserting plate 321 has an inclined surface 3231, and the bottom of the lifting frame 311 has a chamfer 3115. The chamfer 3115 is matched with the shape of the aforementioned inclined surface 3231 to facilitate the insertion end 323 of the inserting plate 321 to automatically slide into between the bottom of the lifting frame 311 and the upper surface of the bottom plate 312, and synchronously lift the lifting frame 311 during the movement of the loading and unloading device 3.

[0086] In this embodiment, if Figure 9 、 Figure 11 and Figure 12 As shown, the insertion end 323 on the plug board 321 is a fork on the side of the plug board 321, and the extension end of the fork has the above-mentioned inclined surface 3231; Figure 10 、 Figure 11 and Figure 12 As shown, the bottom of the lifting frame 311 has chamfers 3115 on either side of the guide post 313. The fork engages with the two chamfers 3115 on the bottom of the lifting frame 311. When the pair of extended ends of the fork are simultaneously inserted into the chamfers 3115 on both sides of the bottom of the lifting frame 311, the lifting frame 311 can be smoothly raised, effectively improving the lifting stability of the bracket 31.

[0087] In one embodiment of the present application, see Figure 13 The clamping device 2 further includes a push-up cylinder 23, a rotary motor 24, and a limit plate 25. The push-up cylinder 23 and the rotary motor 24 are disposed opposite each other at the ends of the limit plate 25. The telescopic top cone 21 is disposed at the output end of the push-up cylinder 23, and the rotary top cone 22 is disposed at the output end of the rotary motor 24. The telescopic top cone 21 and the rotary top cone 22 are coaxially aligned to ensure that the telescopic top cone 21 and the rotary top cone 22 both abut against the center points of the ends of the workpiece 100.

[0088] Thus, the rotating motor 24 drives the rotating top cone 22 to rotate, automatically changing the processed portion of the circumferential surface of the workpiece 100. The push cylinder 23 drives the telescopic top cone 21 toward the rotating top cone 22, using only the ends of the telescopic top cone 21 and the rotating top cone 22 to push against the ends of the workpiece 100, thereby suspending the workpiece 100 in the working position of the roller brush 11. This effectively replaces manual operation and avoids the obstruction of the circumferential surface of the workpiece 100 that can be easily caused by manual operation. This allows the entire circumferential surface of the workpiece 100 to contact the roller brush 11 for polishing and grinding, thereby improving the quality of the finished product.

[0089] In addition, the push cylinder 23 is used to adjust the distance that the telescopic top cone 21 moves toward the rotating top cone 22, thereby effectively adjusting the clamping distance between the telescopic top cone 21 and the rotating top cone 22 to adapt to workpieces 100 of different lengths, thereby improving the applicability of the workpiece 100.

[0090] In this example, see Figure 13 The clamping device 2 also includes a screw mechanism 26, which includes a screw body 261, a movable block 262 and a drive motor 263 for driving the screw body 261 to rotate. The movable block 262 is connected to the limit plate 25. The movable block 262 is installed on the screw body 261 and can drive the limit plate 25 to move along the screw body 261, so as to drive the limit plate 25 and the telescopic top cone 21 and the rotating top cone 22 on the limit plate 25 to move.

[0091] Among them, such as Figure 13 As shown, the screw body 261 is covered with a dustproof plate 264 to prevent dust particles generated during polishing from falling onto the screw body 261 and causing a jam. To accommodate the dustproof plate 264, the movable block 262 includes an upper block, a middle block, and a lower block. The upper and middle blocks are mounted on the dustproof plate 264, with the upper block connected to the aforementioned limit plate 25; the lower block is connected to the middle block and mounted on the screw body 261. This allows the entire movable block 262 to be mounted on the dustproof plate 264, driving the entire limit plate 25 and the telescopic top cone 21 and rotating top cone 22 thereon to move synchronously.

[0092] In this way, the position of the clamping area between the telescopic top cone 21 and the rotating top cone 22 is adjusted by using the screw body 261 mechanism 26, which can not only improve the adaptability of the matching position between the clamping device 2 and the loading and unloading device 3, but also improve the applicability to the specifications of the workpiece 100 being processed, which is conducive to the processing of workpieces 100 with different length specifications.

[0093] Regarding the structure of the driving mechanism 4, in one embodiment of the present application, please refer to Figure 2 、 Figure 14 and Figure 15 The driving mechanism 4 includes a first slider 41, a second slider 42, a slide rail 43 and a linear cylinder 44. The first slider 41 and the second slider 42 are both arranged on the slide rail 43. The loading and unloading device 3 is arranged on the first slider 41, and the grinding device 1 is connected to the output end of the linear cylinder 44.

[0094] In this embodiment, if Figure 2 、 Figure 3 and Figure 14As shown, the drive mechanism 4 includes two parallel slide rails 43, each with a first slider 41 and a second slider 42. The first sliders 41 and second sliders 42 on the two slide rails 43 are aligned, allowing the loading and unloading device 3 to be mounted on the same first slider 41 and the grinding device 1 to be mounted on the same second slider 42. A linear cylinder 44 is provided on one side of the slide rails 43, near the second slider 42, allowing the grinding device 1 to be mounted on the second slider 42 and easily connected to the output end of the linear cylinder 44.

[0095] The bottom of the grinding device 1 is provided with a slide plate 12 , which is fixed to the second sliding block 42 through the slide plate 12 . The slide plate 12 is connected to the loading and unloading device 3 via a connecting piece 45 .

[0096] In this embodiment, if Figure 15 As shown, the connecting member 45 may preferably be a connecting plate that connects the slide plate 12 to the base plate 322 of the loading and unloading device 3. In other embodiments (not shown), the connecting member 45 may also be a connecting rod, etc., as long as it can connect and fix the two components, which is not specifically limited here.

[0097] Thus, the grinding device 1 and the loading and unloading device 3 are both fixed to corresponding sliders of the slide rail 43 and connected together by a connector 45. When the linear cylinder 44 drives the grinding device 1 to move, it also drives the loading and unloading device 3 to move, allowing both to move along the slide rail 43, thereby achieving synchronous reciprocating movement of the loading and unloading device 3 and the grinding device 1.

[0098] In order to match the structure of the driving mechanism 4, in this embodiment, please refer to Figure 13 、 Figure 15 and Figure 16 The clamping device 2 further includes a base 27 for supporting the telescopic top cone 21 and the rotating top cone 22. The base 27 is disposed between the first slider 41 and the second slider 42. The bottom of the base 27 has grooves 271 for engaging the slide rails 43 and the connector 45, respectively. Thus, the grooves 271 at the bottom of the base 27 are cleverly utilized to allow the slide rails 43 and connector 45 of the drive mechanism 4 to pass through, allowing both to be inserted into the clamping device 2. This helps prevent interference when the drive mechanism 4 drives the loading and unloading device 3 and the grinding device 1 to move synchronously back and forth, effectively improving the compactness of the various components in the equipment.

[0099] In this embodiment, if Figure 11 、 Figure 12 and Figure 13 As shown, a convex retaining rib 272 is provided on the side of the base 27, and the retaining rib 272 corresponds to the position of the bracket 31 of the loading and unloading device 3. When the loading and unloading device 3 is close to the clamping device 2, as shown in FIG. Figure 11 and Figure 12 As shown, the retaining rib 272 here abuts the bottom plate 312 of the bracket 31; at the same time, the base plate 322 continues to move toward the bottom plate 312 when the telescopic assembly 33 is in the contracted state, so that the insertion end 323 of the insert plate 321 on the base plate 322 can be inserted into the bottom of the lifting frame 311 to lift the lifting frame 311, thereby supporting the workpiece 100 between the telescopic top cone 21 and the rotating top cone 22.

[0100] Regarding the driving mechanism 4 on the deburring device of the present application, in other embodiments (not shown), the driving mechanism 4 may also include a linear cylinder 44 and a movable frame (not shown) connected to the linear cylinder 44, the movable frame including two mutually connected frames or placement tables (not shown) located on both sides of the clamping device 2, and the grinding device 1 and the loading and unloading device 3 are respectively arranged on each frame or placement table. When the linear cylinder 44 drives the above-mentioned movable frame to move, it can also synchronously drive the grinding device 1 and the loading and unloading device 3 to reciprocate with the clamping device 2 as the center point, thereby realizing the processing operations of loading, grinding and unloading.

[0101] Regarding the structure of the grinding device 1, in one embodiment of the present application, please refer to Figure 17 The grinding device 1 further includes a driver 13, a transmission assembly 14, and a speed regulator 15. The transmission assembly 14 includes a driving wheel 141, a driven wheel 142, and a transmission belt 143. The transmission belt 143 is mounted on the driving wheel 141 and the driven wheel 142. The driver 13 is disposed adjacent to the roller brush 11, and the output end of the driver 13 is connected to the driving wheel 141. The speed regulator 15 is transmission-connected between the driven wheel 142 and the roller brush 11.

[0102] This allows the driver 13 and the roller brush 11 to be arranged in a compact position, avoiding the space waste caused by a linear connection structure, which helps to reduce the overall size of the grinding device 1. In addition, the speed regulator 15 is used to adjust the speed of the roller brush 11, thereby improving the adjustability of the grinding device 1.

[0103] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
