Specific embodiments

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will combine the accompanying Figure 1 - 20 drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are some, rather than all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] A blade clamping device includes a feeding device and a clamping device. The feeding device can push the processed blade 4 out of the clamping device while pushing the blade 4 to be processed into the clamping device, and clamp the blade 4 through the clamping device for subsequent processing.

[0044] The feeding device includes a conveying channel 30, a filling mechanism 40, a silo 501, a pushing mechanism, and a silo 501 traveling device. The conveying channel 30 is horizontally arranged above the silo 501, and an outlet is provided on the lower side of the conveying channel 30. A second elastic clip 301 is fixedly arranged inside the conveying channel 30 near the outlet. An interval for clamping a single blade 4 is formed between the second elastic clip 301 and the side wall of the conveying channel 30. When the blade 4 moves to this interval, the blade 4 is clamped under the action of the second elastic clip 301, which can limit the position of the blade 4 and prevent the blade 4 from excessive displacement, so as to ensure that multiple blades 4 located in the conveying channel 30 are all at the set positions, facilitating the subsequent pushing of the blades 4.

[0045] The filling mechanism 40 is arranged above the conveying channel 30. The filling mechanism 40 includes a blanking plate 401, a blanking cylinder 402, a connecting seat 403, and a sensing mechanism 404 for detecting the moving stroke of the blanking cylinder 402. In this application, the blanking cylinder 402 can be selected from other linear motion devices such as a hydraulic cylinder or a servo electric push rod. In this embodiment, a hydraulic cylinder is taken as an example.

[0046] The sensing mechanism 404 includes an upper sensor 4041, a lower sensor 4042, and a full material sensor 4043. The lower sensor 4042 can detect the state of whether there is a blade 4 in the silo 501 and feedback it to the filling mechanism 40. The blanking plate 401 pushes the blade 4 directly below it into the silo 501. When the blanking plate 401 pushes the blade 4 to the bottom of the silo 501 or contacts the other blades 4 in the silo 501, the blanking plate 401 moves upward in the reverse direction. At this time, the upper sensor 4041 can detect the moving position of the blanking plate 401, so that the blanking plate 401 returns to its original position; repeat the above operation until the full material sensor 4043 detects that the silo 501 is filled with blades 4, and then the filling mechanism 40 stops working.

[0047] The blanking plate 401 is vertically arranged, and the plate surface of the blanking plate 401 and the blade 4 at the outlet of the conveying channel 30 are in the same plane. The upper end of the blanking plate 401 is fixedly connected to the connecting seat 403, and the lower end is a free end. The connecting seat 403 is horizontally arranged above the blanking cylinder 402, and the connecting seat 403 is fixedly connected to the piston rod 12 of the blanking cylinder 402. A guide plate 4021 is fixedly arranged outside the blanking cylinder 402. A guide groove is formed between the guide plate 4021 and the blanking cylinder 402. The lower end of the blanking plate 401 can penetrate through the guide groove. When the blanking cylinder 402 is started, the blanking cylinder 402 drives the blanking plate 401 to move up and down synchronously through the connecting seat 403, so that the lower end edge of the blanking plate 401 can abut against the upper edge of the blade 4, and then the blade 4 is pushed from the conveying channel 30 into the silo 501.

[0048] The silo 501 is vertically arranged below the conveying channel 30. An inlet for the blade 4 to enter is provided above the silo 501. When the inlet of the silo 501 is communicated with the outlet of the conveying channel 30, the blade 4 sequentially enters the interior of the silo 501 through the outlet of the conveying channel 30 and the inlet of the silo 501 and is vertically stacked on top of each other inside the silo 501. An outlet is provided on the front side of the silo 501. A cover plate 80 is also provided at the outlet of the silo 501. When the cover plate 80 is closed at the outlet, it can prevent the blade 4 from falling out of the silo 501.

[0049] There are multiple silos 501. The multiple silos 501 are arranged side by side to form the overall silo 50, and there is no communication between adjacent silos 501. The cover plate 80 covers the outlets of the multiple silos 501. The cover plate 80 can slide up and down along the length direction of the overall silo 50. The walking device of the silo 501 can drive a single silo 501 to align with the outlet of the conveying channel 30.

[0050] A material combing mechanism 90 is also provided below the overall silo 50. The material combing mechanism 90 includes a combing block 901 arranged in a rectangle. A plurality of teeth 902 are integrally formed on the combing block. The plurality of teeth 902 are equidistantly arranged along the length direction of the combing block 901. The teeth 902 can extend into the clamping device. When the clamping device moves from bottom to top, the teeth 902 can insert into the interior of the clamping device and push the blade 4 inside the clamping device from top to bottom, facilitating the pushing out of the processed blade 4.

[0051] A washing liquid channel 903 is provided on the combing block 901. The washing liquid channel 903 is located above the plurality of teeth 902. The washing liquid channel 903 is communicated with the cutting fluid of the machine tool itself. The cutting fluid of the machine tool is used to supply the flushing liquid to the washing liquid channel 903. The flushing direction of the cutting fluid covers the upper end surfaces of the plurality of teeth 902. Through the cooperation of the teeth 902 and the cutting fluid, the cleaning of the grinding debris in the clamping device is realized.

[0052] The walking device of the silo 501 includes a slider 701, a base 702 and a driving mechanism. The slider 701 is arranged in a rectangle. One side of the slider 701 is fixedly connected to the overall silo 50, and the other side is connected to the base 702. The base 702 includes a movable block 7021 and a fixed block 7022. The slider 701 is fixedly connected to the movable block 7021. The driving mechanism can drive the movable block 7021 to slide relative to the fixed block 7022. The moving direction of the movable block 7021 is the same as the arrangement direction of the multiple silos 501.

[0053] The driving mechanism includes a motor 7031, a lead screw 7032 and a nut 7033. The motor 7031 is preferably a servo motor 7031. The motor 7031 is fixedly arranged outside the base 702, and the output shaft of the motor 7031 extends into the inside of the base 702. The lead screw 7032 is rotatably arranged inside the base 702, and the lead screw 7032 and the output shaft of the motor 7031 rotate coaxially.

[0054] The nut 7033 is sleeved outside the lead screw 7032 and is threadedly connected to the lead screw 7032. A connecting block is fixedly arranged on the movable block 7021, and the connecting block is fixedly connected to the nut 7033. Moreover, a straight surface is arranged on the outer peripheral surface of the nut 7033, and this straight surface is in contact with the inner wall of the base 702. Under the action of the movable block 7021 and the straight surface, the nut 7033 can only reciprocate along the length direction of the lead screw 7032.

[0055] Four support sliders 704 are fixedly arranged at the corners of the base 702. The movable block 7021 is respectively slidably connected to the four support sliders 704, which can not only stably support the movable block 7021, but also reduce the friction between the movable block 7021 and the base 702, facilitating the movable block 7021 to drive the slider 701 to move. At the same time, since the length of the support slider 704 is certain, the moving distance of the movable block 7021 can be further limited.

[0056] The pushing mechanism is arranged at the rear side of the bin 501. The pushing mechanism includes a push rod 601, a second cylinder 602 and a fixed seat 603. The number of the push rods 601 is equal to the total number of the blades 4 in the bin 501 when it is full. In this application, the second cylinder 602 can be selected from other linear motion devices such as a hydraulic cylinder or a servo electric push rod. In this embodiment, a hydraulic cylinder is taken as an example.

[0057] A cavity is arranged inside the fixed seat 603. A push plate 604 is slidably connected inside the cavity. The push plate 604 is parallel and opposite to the cover plate 80. The end of the second cylinder 602 extends into the inside of the fixed seat 603 and is fixedly connected to the push plate 604, so as to be able to drive the push plate 604 to slide back and forth in the cavity of the fixed seat 603.

[0058] A plurality of push rods 601 are all arranged inside the fixed seat 603, and the push rods 601 are connected to the push plate 604. Buffer blind holes are arranged on the push plate 604. One end of the push rod 601 is inserted into the buffer blind hole and the other end can extend to the outside of the fixed seat 603. When the push plate 604 is in contact with the inner wall of the fixed seat 603 on the side far from the cover plate 80, the push rod 601 is completely received inside the fixed seat 603. At this time, the arrangement of the push rod 601 does not prevent the blade 4 from entering the bin 501.

[0059] A second spring 605 is also provided inside the buffer blind hole. The end of the ejector rod 601 is connected to the second spring 605. The second cylinder 602 drives a plurality of ejector rods 601 to be pushed out simultaneously through a push plate 604. After removing the shielding of the cover plate 80 from the discharge port of the bin 501, the second cylinder 602 is started, and the ejector rod 601 can push the blade 4 in the bin 501 out of the bin 501 outlet.

[0060] The clamping device includes a main body 1 and a side cover 2 provided on the side of the main body 1; the main body 1 is provided with floating clamping pieces 3, a blade 4 is arranged between the floating clamping pieces 3, an oil cylinder 5 is arranged on the side of the floating clamping piece 3, and the oil cylinder 5 presses the floating clamping piece 3 and the blade 4 tightly against the main body 1; a first oil passage 6 is arranged inside the main body 1, a second oil passage 7 communicated with the first oil passage 6 is arranged inside the side cover 2, and the second oil passage 7 is communicated with the oil cylinder 5. The first oil passage 6 on the main body 1 is communicated with the second oil passage 7 on the side cover 2. The oil cylinder 5 is driven by hydraulic oil, and the floating clamping piece 3 and the blade 4 are clamped through the oil cylinder 5. After clamping, the blade 4 can be processed subsequently.

[0061] The main body 1 is provided with a plurality of accommodating grooves 8, the floating clamping pieces 3 are arranged in the accommodating grooves 8, the accommodating grooves 8 are separated by convex blocks 9, the edge of the blade 4 abuts against the convex block 9, and the edge of the side of the blade 4 away from the convex block 9 is higher than the main body 1.

[0062] The edge of the blade 4 is higher than the main body 1, which is convenient for processing the blade 4. The floating clamping pieces 3 are arranged in the accommodating grooves 8, which limits the movement range of the floating clamping pieces 3 and ensures that a certain distance can be maintained between the floating clamping pieces 3, facilitating the installation of the blade 4. The edge of the blade 4 abuts against the convex block 9, and at the same time, the oil cylinder 5 clamps the floating clamping piece 3 and the blade 4, making the blade 4 more stable.

[0063] A through rod 10 is arranged inside the main body 1. The through rod 10 passes through the convex block 9. A plurality of floating clamping pieces 3 are sleeved on the through rod 10 and can move along the through rod 10. A blade 4 is arranged between a plurality of floating clamping pieces 3. Two through rods 10 pass through each floating clamping piece 3. In this embodiment, a set of floating clamping pieces 3 is arranged from top to bottom, and two through rods 10 pass through each set of floating clamping pieces 3, ensuring the stability of the floating clamping pieces 3.

[0064] A plurality of oil cylinders 5 are arranged on the main body 1 from top to bottom. The oil cylinder 5 includes an oil cylinder 5 cavity structure arranged inside the main body 1 and a piston 12 arranged inside the oil cylinder 5 cavity structure. The second oil passage 7 is communicated with the oil cylinder 5 cavity structure. A disc spring 13 is arranged between the piston 12 and the main body 1. The disc spring 13 and the oil outlet of the second oil passage 7 are respectively on both sides of the piston 12.

[0065] The hydraulic oil passes through the first oil passage 6 and the second oil passage 7 and enters the cavity structure of the oil cylinder 5, pushing the piston 12. The piston 12 pushes the floating clamping piece 3 and the blade 4, and at the same time compresses the disc spring 13 to clamp the blade 4. After the blade 4 is processed, the hydraulic oil flows back, and the piston 12 retracts under the action of the disc spring 13 to release the floating clamping piece 3 and the blade 4.

[0066] The second oil passage 7 includes a connecting oil passage 14, a transverse oil passage 15, a longitudinal oil passage 16 and a branch oil passage 17 that are connected in sequence. The connecting oil passage 14 connects the first oil passage 6 with the transverse oil passage 15. One end of the transverse oil passage 15 is connected to the longitudinal oil passage 16, and the other end is provided with a plugging plug 18. A number of branch oil passages 17 are provided on the longitudinal oil passage 16, and the branch oil passages 17 are connected to the oil cylinder 5. Plugging plugs 18 are provided on both sides of the longitudinal oil passage 16.

[0067] The cavity structure of the oil cylinder 5 is opened on the main body 1, and then sealed by adding a sealing ring. The first oil passage 6 is machined on the main body 1, and the second oil passage 7 is machined on the side cover 2, and then the end is plugged by the plugging plug 18. The branch oil passage 17 is correspondingly arranged with the oil cylinder 5 to supply oil to the oil cylinder 5.

[0068] This embodiment further includes a blade 4 drag plate. The main body 1 is fixed with a cylinder 20. The end of the piston rod of the cylinder 20 is fixedly connected to the blade 4 drag plate. The blade 4 drag plate is arranged below the blade 4. The cylinder 20 is used to drive the blade 4 drag plate away from below the blade 4.

[0069] When the blade 4 enters the clamping device, multiple blades 4 are simultaneously pushed between the floating clamping pieces 3. Before the blade 4 is clamped by the oil cylinder 5, under the action of gravity, it is supported by the blade 4 drag plate. After processing, the oil cylinder 5 releases the blade 4, and the cylinder 20 drives the blade 4 drag plate away from below the blade 4. The blade 4 leaves the clamping device under the action of gravity.

[0073] When the blade 4 moves to the outlet of the conveying channel 30, the second elastic clip 301 can clamp the blade 4, which can realize the limitation of the position of the blade 4 and ensure that multiple blades 4 located in the conveying channel 30 are all in the set positions;

[0074] The blanking cylinder 402 drives the blanking plate 401 to move downward, and pushes the blade 4 located at the front side of the second elastic clip 301 out of the bin 501. The sensor mechanism 404 can timely feedback the movement stroke of the blanking cylinder 402 to determine whether the bin 501 is full. When the bin 501 is full, the alignment structure drives the next bin 501 to align with the outlet of the conveying channel 30 again, and the above operation is repeated until all the bins 501 are in a full state.

[0075] S2: The clamping device body 1 and the silo 50 are brought close together, and the clamping device body 1 is driven to move upward from bottom to top. During the movement of the body 1, the cover plate 80 of the silo 50 can be pushed upward to remove the cover plate 80 from blocking the outlet of the silo 501 until the body 1 is completely aligned with the silo 50;

[0076] Then start the second cylinder 602, and push the multiple blades 4 in the silo 501 into between the adjacent floating clamping plates 3 of the main body 1 through the push rod. The first oil circuit 6 on the main body 1 is connected with the second oil circuit 7 on the side cover 2, and the cylinder 5 is driven by hydraulic oil. The floating clamping plates 3 and the blades 4 are clamped by the cylinder 5, and the clamped blades 4 can be processed later.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
