Description

Technical Field

[0001] The automatic deburring and grinding machine of the utility model belongs to the technical field of machining, and specifically relates to an automatic device for double-sided deburring of thin parts with a round hole in the middle. Background Technique

[0002] Burrs on mechanical parts are caused by plastic deformation during the cutting process in some cases; some are flash from casting, die forging and other processes, and some are residual materials extruded by welding. With the improvement of industrialization and automation, in the field of machining, especially in the fields of aviation, aerospace, instrumentation, with the improvement of the manufacturing accuracy requirements of mechanical parts and the miniaturization of mechanism design, the harm of burrs is particularly obvious, which has gradually attracted widespread attention, and people have begun to study the generation mechanism and removal methods of burrs.

[0003] The commonly used deburring methods now include manual, chemical, electrolytic and other methods. In the current era of high-efficiency production and processing requirements, the mechanization and automation of deburring workpieces using surface deburring grinding brushes have become the production trend. However, the current deburring of workpieces still requires workers to position and lock the workpieces, and then quickly grind the surface of the workpieces with grinding brushes. For workpieces with a thin middle part and a round hole, positioning, locking and double-sided grinding are required, which is more difficult and time-consuming. In order to further realize deburring automation and mechanization and liberate the labor force, it is necessary to develop a set of equipment that can automatically pick up, lock and deburr workpieces. Content of the Utility Model

[0004] In order to solve one of the above technical defects, the utility model provides an automatic deburring and grinding machine, which performs double-sided deburring and grinding on thin parts, improves processing efficiency and reduces labor costs.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments in the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0033] As Figure 1 shown, an automatic deburring and grinding machine includes a work platform 1, a turntable 2, a workpiece feeding and taking combined mechanism 3, a workpiece positioning mechanism 4, a front grinding mechanism 5, a flipping mechanism 6, a reverse grinding mechanism 7 and a control box;

[0034] The work platform 1 is fixed to the ground through a base;

[0035] A turntable 2 is rotatably installed at the center on the top of the work platform 1, and a rotation power device is installed inside or on one side of the turntable 2, and the rotation power device drives the turntable 2 to rotate;

[0036] A plurality of workpiece positioning mechanisms 4 for positioning and locking workpieces are fixedly installed on the top surface of the turntable 2;

[0037] On the working platform 1, a workpiece feeding and picking combined mechanism 3, a front grinding mechanism 5, a flipping mechanism 6, and a back grinding mechanism 7 are successively and fixedly installed around the turntable 2.

[0038] A control box is fixedly installed on the working platform 1. The components inside the control box control the rotation of the turntable 2 through a rotating power device, so that each workpiece positioning mechanism 4 stays at fixed points in sequence and circulates between the workpiece feeding point of the workpiece feeding and picking combined mechanism 3, the front grinding mechanism 5, the flipping mechanism 6, the back grinding mechanism 7, and the workpiece picking point of the workpiece feeding and picking combined mechanism 3. When the workpiece positioning mechanism 4 reaches the workpiece feeding point of the workpiece feeding and picking combined mechanism 3, the workpiece feeding and picking combined mechanism 3 places the workpiece on the workpiece positioning mechanism 4. The workpiece positioning mechanism 4 clamps the workpiece and sends it to the front grinding mechanism 5. The front grinding mechanism 5 starts to grind and deburr the front side of the workpiece, then sends it to the flipping mechanism 6 to flip the workpiece so that the back side faces up, and then sends it to the back grinding mechanism 7. The back grinding mechanism 7 starts to grind and deburr the back side of the workpiece, and finally sends it to the workpiece picking point of the workpiece feeding and picking combined mechanism 3. The workpiece feeding and picking combined mechanism 3 takes the workpiece off the turntable 2, and thus the double-sided deburring of one workpiece can be completed.

[0039] The following specifically describes the workpiece feeding and picking combined mechanism 3, the workpiece positioning mechanism 4, the front grinding mechanism 5, the flipping mechanism 6, and the back grinding mechanism 7 in the present utility model with reference to the accompanying drawings.

[0040] As Figure 2 shown, the workpiece feeding and picking combined mechanism 3 includes a track 31, a moving seat 32, a lifting platform 33, a workpiece feeding gripper 34, a workpiece picking gripper 35, a workpiece pushing cylinder 36, and a lifting cylinder 37. The track 31 is fixedly laid on the working platform 1, and the moving seat 32 is slidably installed on the track 31. The cylinder block of the workpiece pushing cylinder 36 is fixed on the working platform 1, and the end of the piston rod of the workpiece pushing cylinder 36 is fixed at one end of the moving seat 32. The workpiece pushing cylinder 36 pushes the moving seat 32 to move on the track 31 to approach or move away from the turntable 2. Above the moving seat 32, a lifting platform 33 is installed through a plurality of telescopic guide rods 38. The cylinder block of the lifting cylinder 37 is fixedly installed on the bottom surface of the lifting platform 33. The end of the piston rod of the lifting cylinder 37 is vertically downward and is fixedly connected to the top surface of the moving seat 32 through an extension rod 39. The piston rod of the lifting cylinder 37 expands and contracts to make the lifting platform 33 perform short-distance lifting. The workpiece feeding gripper 34 and the workpiece picking gripper 35 are fixedly installed on the lifting platform 33. When the moving seat 32 approaches the turntable 2, both the workpiece feeding gripper 34 and the workpiece picking gripper 35 are located directly above the running track of the workpiece positioning mechanism 4. The workpiece feeding gripper 34 places the workpiece to be processed held by it on the workpiece positioning mechanism 4 that stays at a fixed point below it, and the workpiece picking gripper 35 grabs the processed workpiece on the workpiece positioning mechanism 4 that stays at a fixed point below it.

[0041] As Figure 3As shown, the delivery clamp 34 includes a clamping cylinder 341, a palm seat 342, a joint 343 and a grasping finger 344;

[0042] The clamping cylinder 341 is provided with a palm seat 342 fixed at the end of the cylinder body of the piston rod. The palm seat 342 is a long block with a C-shaped groove. Two joints 343 are symmetrically installed in the C-shaped groove of the palm seat 342. The joints 343 are L-shaped block structures. The corners of the joints 343 are hinged in the C-shaped groove of the palm seat 342. The piston rod of the clamping cylinder 341 passes through the palm seat 342 to the inside of its C-shaped groove and a connecting block is fixed at the end of the piston rod. The connecting block is hinged to one end of the two joints 343 close to the center of the C-shaped groove of the palm seat 342. The other ends of the two joints 343 are fixedly installed with grasping fingers 344, and the two grasping fingers 344 are symmetrically arranged.

[0043] The structure of the piece-removing clamp 35 is the same as that of the piece-delivering clamp 34 .

[0044] The clamping cylinder bodies of the delivery clamping jaws 34 and the pickup clamping jaws 35 are fixed on the lifting platform. Figure 3 When the piston rod of the workpiece delivery clamp 34 is extended, the connecting block at the end of the piston rod drives the hinged joint end to move, thereby realizing the mutual retraction and expansion between the other ends of the two joints, thereby clamping or releasing the workpiece located between the two grasping fingers.

[0045] like Figure 3 As shown in, the working platform 1 is equipped with a material picking platform 8 and a long feeding groove 9, and the material picking platform 8 is fixed on one side of the feeding and picking combined mechanism 3. When the moving seat 32 is away from the turntable 2, the material picking platform 8 is located directly below the two grasping fingers 344 of the feeding clamp 34, so that the workpiece on the material picking platform 3 can be grabbed, and then when the moving seat 32 is close to the turntable 2, the grabbed workpiece can be sent to the workpiece positioning mechanism 4. The side of the material picking platform 8 away from the feeding and picking combined mechanism 3 is fixedly equipped with an inclined feeding long groove 9, and the lower end of the feeding long groove 9 is connected to the material picking platform 8, and multiple workpieces can be placed in the feeding long groove 9 in sequence, and the workpiece slides down to the material picking platform 8 for continuous feeding. In the utility model, a groove is set on the top surface of the material picking platform 8 and an in-place monitor is installed in the groove to monitor the feeding and positioning status of the workpiece.

[0046] A finished part guide plate is also fixedly installed on the working platform 1. The finished part guide plate is tilted, and when the moving seat 32 is away from the turntable 2, the higher end of the finished part guide plate is located directly below the two gripping fingers of the picking clamp 35, so that the picking clamp 35 can place the finished workpiece on the finished part guide plate, and the lower end of the finished part guide plate corresponds to the finished product collection box, so that the workpiece on it slides into the finished product collection box.

[0047] like Figure 4As shown in the figure, the workpiece positioning mechanism 4 includes a pneumatic slip ring 41 and a three-jaw cylinder 42. The pneumatic slip ring 41 is vertically fixed on the turntable 2, and a three-jaw cylinder 42 is fixedly installed at the top of the pneumatic slip ring 41. Components inside the control box control the operation of the pneumatic slip ring 41 to make the three-jaw cylinder 42 rotate around the vertical central axis. The axis of the three-jaw cylinder 42 is vertically arranged, and its top is a fixed part platform 43. Components inside the control box control the expansion and contraction of the three jaws of the three-jaw cylinder 42.

[0048] The pneumatic slip ring 41 in the present utility model includes a rotating component and a device capable of transmitting gas signals or power in the rotating component. Its main function is to drive the rotation of the three-jaw cylinder 42 while ensuring the smooth operation of the rotating component and the stability of the gas path transmission, improving the reliability and safety of the equipment. The pneumatic slip ring and its included rotating components are all prior arts, and their specific structures are not described in detail in the present utility model.

[0049] The main components of the three-jaw cylinder include a cylinder body, internal finished parts, and three movable claws. Under the control of the air source, the three-jaw cylinder drives the three movable claws to move relatively balancedly through the movement of the cylinder body to achieve the purpose of clamping the workpiece. Its structure is simple and compact, and the three claws can cooperate with each other to complete the operation of clamping or loosening the workpiece. The structure of the three-jaw cylinder is prior art and is not described in detail in the present utility model.

[0050] As Figure 5 shown in the figure, the front grinding mechanism 5 includes a mounting seat 51, a vertical column 52, a sliding seat 53, a grinding motor 54, and a grinding brush 55. The mounting seat 51 is fixed on the working platform 1, and a fine-tuning structure can also be provided on the mounting seat 51 to adjust its mounting position on the working platform 1. The vertical column 52 is fixedly installed on the mounting seat 51 through a rotary fine-tuning connection mechanism with a locking mechanism. The sliding seat 53 is slidably installed on the vertical column 52, and the sliding seat 53 is provided with a height adjustment mechanism. Components inside the control box control the height adjustment mechanism to realize the up and down movement of the sliding seat 52 on the vertical column 52. The height adjustment mechanism is prior art, and there are various implementation schemes for the automated structure that can realize the up and down movement of the sliding seat 53 on the vertical column 52. The present utility model does not elaborate on this structure in detail. The grinding motor 54 is fixed on the sliding seat 53, and a grinding brush 55 is fixedly installed at the end of the output shaft of the grinding motor 54; the rotary fine-tuning connection mechanism can adjust the rotation angle of the vertical column 52 and lock it, thereby affecting the corresponding point position relationship of the grinding brush 55 on the turntable 2 to ensure that it can cover the workpiece that stops at a fixed point. The sliding seat 53 slides up and down on the vertical column 52 to perform height adjustment to achieve the contact grinding or separation operation with the workpiece; the grinding motor 54 can also be fixedly installed on the sliding seat 53 through a rotary fine-tuning connection mechanism with a locking mechanism.

[0051] The structure of the reverse grinding mechanism 7 is the same as that of the front grinding mechanism 5.

[0052] As Figure 6 shown, the turnover mechanism 6 includes a three-rod cylinder 61, a rotary cylinder 62 and a workpiece-turning gripper 63;

[0053] The cylinder block of the three-rod cylinder 61 is fixed on the working platform 1. The piston rod of the three-rod cylinder 61 is vertically upward and a rotary cylinder 62 is fixedly installed at its end. A workpiece-turning gripper 63 is installed on the lateral side of the rotary cylinder 62. The structure of the workpiece-turning gripper 63 is the same as that of the workpiece-feeding gripper 34, and the operation implementation process is also the same. The components inside the control box control the operation of the rotary cylinder 62 to make the workpiece-turning gripper 63 rotate around the lateral central axis. The structure of the rotary cylinder 62 is a prior art, and its specific structure is not described in detail in the present utility model. The three-rod cylinder 61 controls the workpiece-turning gripper 63 to descend to grasp the workpiece below and then rise. The rotary cylinder 62 controls the workpiece-turning gripper 63 to turn the workpiece by 180°, and then place it on the workpiece positioning mechanism 4 below.

[0054] As Figure 1 shown, five workpiece positioning mechanisms 4 are fixedly installed on the top surface of the turntable 2. When the turntable 2 rotates and stops at a fixed point, the five workpiece positioning mechanisms 4 are respectively located at the workpiece-feeding point of the workpiece-feeding and -taking combined mechanism 3, the front grinding mechanism 5, the turnover mechanism 6, the reverse grinding mechanism 7 and the workpiece-taking point of the workpiece-feeding and -taking combined mechanism 3. In the case of having five workpiece positioning mechanisms 4, each time it stops at a fixed point, corresponding workpieces at the workpiece-feeding point of the workpiece-feeding and -taking combined mechanism 3, the front grinding mechanism 5, the turnover mechanism 6, the reverse grinding mechanism 7 and the workpiece-taking point of the workpiece-feeding and -taking combined mechanism 3 perform the processes at this point, which is the most optimized structural scheme, that is, the fixed points of the five workpiece positioning mechanisms 4 are an equilateral pentagon centered on the rotation axis of the turntable 2.

[0055] Taking a single ring-shaped thin workpiece as an example, the following describes in detail its processing (double-sided burr grinding) process on the present utility model:

[0056] Feeding: The workpiece is placed on the feeding long groove 9 and slides down to the picking platform 8. The positioning monitor on the picking platform 8 detects that the workpiece is in place. The piston rod of the pushing cylinder 36 of the pick-and-place integrated mechanism 3 retracts, causing the moving seat 32 to drive the lifting platform 33 and the feeding gripper 34 thereon away from the turntable 2 until the feeding gripper 34 reaches above the picking platform 8. Then the piston rod of the lifting cylinder 37 retracts, bringing the feeding gripper 34 to the same plane as the workpiece. Then the piston rod of the clamping cylinder 341 retracts, and the two gripper fingers 344 close to grip the workpiece tightly. Then the piston rod of the lifting cylinder 37 extends, causing the feeding gripper 34 to drive the workpiece upward. Then the piston rod of the pushing cylinder 36 extends, causing the moving seat 32 to drive the lifting platform 33 and the feeding gripper 34 thereon close to the corresponding workpiece positioning mechanism 4 above the turntable 2. The piston rod of the clamping cylinder 341 extends, and the two gripper fingers 344 expand to release the workpiece, and the workpiece falls on the workpiece positioning mechanism 4. The three claws of the three-jaw cylinder 42 expand the inner ring of the workpiece on the positioning platform 43 to clamp it tightly;

[0057] Front grinding: Under the command of the components inside the control box, the turntable 2 rotates by 1 / 5, and the workpiece positioning mechanism 4 drives the workpiece to directly below the grinding brush 55 of the front grinding mechanism 5 (before starting the program, both the front grinding mechanism 5 and the back grinding mechanism 7 have been adjusted to appropriate positions). The grinding motor 54 is started to make the grinding brush 55 rotate at high speed. The sliding seat drives the grinding motor 54 to move downward until the grinding brush 55 contacts a part of the workpiece and conducts grinding. The pneumatic slip ring 41 of the workpiece positioning mechanism 4 drives the three-jaw cylinder 42 and the workpiece thereon to rotate, so that the grinding brush 55 conducts comprehensive grinding on the front of the workpiece to remove burrs. After a certain period of time, the front grinding mechanism 5 resets and the grinding motor 54 stops working. Thus, the burr removal on the front of the workpiece is completed;

[0058] Workpiece flipping: Under the command of the components inside the control box, the turntable 2 rotates by 1 / 5, and the workpiece positioning mechanism 4 drives the workpiece to directly below the flipping mechanism 6. The three-bar cylinder 61 controls the flipping gripper 63 to descend to grab the workpiece below and then rise. The slewing cylinder 62 controls the flipping gripper 63 to flip the workpiece by 180°, and then place it on the workpiece positioning mechanism 4 below. The clamping and releasing of the workpiece by the flipping gripper 63 are implemented in the same way as the feeding gripper 34;

[0059] Back grinding: Under the command of the components inside the control box, the turntable 2 rotates by 1 / 5, and the workpiece positioning mechanism 4 drives the workpiece to directly below the grinding brush of the back grinding mechanism 7. The implementation process of the grinding operation on the back of the workpiece is the same as the above-mentioned front grinding;

[0060] Finished product picking: Under the command of the components inside the control box, the turntable 2 rotates by 1 / 5, and the workpiece positioning mechanism 4 drives the workpiece to the picking point of the picking and feeding combined mechanism 3. The finished workpiece is grasped by the picking gripper 35. The grasping operation process is the same as that of the feeding gripper 34. Then, the piston rod of the lifting cylinder 37 extends to drive the picking gripper 35 to lift the workpiece. Then, the piston rod of the workpiece pushing cylinder 36 retracts to drive the moving seat 32 to drive the lifting platform 33 and the picking gripper 35 thereon away from the corresponding workpiece positioning mechanism 4 above the turntable 2. The picking gripper 35 releases the workpiece, and the workpiece falls onto the finished product guide plate and then falls into the finished product collection box along the finished product guide plate.

[0061] This utility model only describes the equipment structure. The components inside the control box control the start, stop, and operation of all cylinders and electrical appliances, and are equipped with corresponding monitors to cooperate with monitoring the positioning of workpieces and other situations, thereby realizing automated operation. It is set according to actual needs, and specific details are not described in detail here.
