Description

Technical Field

[0001] This utility model relates to the field of cemented carbide CNC cutting tool production technology, specifically a clamping device for cemented carbide CNC cutting tool production. Background Technology

[0002] Carbide is widely used as a cutting tool material, such as turning tools, milling cutters, planing tools, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel and tool steel. When machining carbide inserts, a clamping device is required for fixation. Existing carbide insert clamping devices use clamping devices to fix the two ends of the insert during machining. However, carbide inserts come in many different shapes and sizes, making it difficult for clamping devices to adapt to the fixation of various inserts.

[0003] However, most common carbide CNC inserts on the market have a center mounting hole. Therefore, when clamping carbide CNC inserts, using a clamping structure that is compatible with the center mounting hole can solve the problem that a single clamping structure cannot clamp them because of their different shapes.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Please see Figures 1-9 This utility model provides a technical solution: a clamping device for producing cemented carbide CNC cutting tools, including a clamping fixture 5 for clamping cutting tools;

[0035] Tooling mounting assembly 4 for installing and adjusting clamping tooling 5;

[0036] The three-axis adjustment component 3 is used to adjust the tooling installation component 4;

[0037] Electric lifting assembly 2 for lifting three-axis adjustment assembly 3;

[0038] And a rotating assembly 1 for the direction of rotation;

[0039] The clamping fixture 5 includes a mounting base 501. A piston cylinder 502 is fixedly mounted on the bottom of the mounting base 501. A piston 503 is slidably disposed inside the piston cylinder 502. An air inlet pipe and an exhaust pipe are disposed on the piston cylinder 502. The piston 503 is located below the air inlet pipe and the exhaust pipe. A cross 504 is fixedly mounted on the inner wall of the piston cylinder 502. A fixing rod 505 is fixedly mounted on the bottom of the cross 504. A base plate 507 is fixedly mounted on the bottom end of the fixing rod 505. A guide groove 509 is formed on the outer wall of the fixing rod 505. A hinge rod 508 is slidably disposed in the guide groove 509. A clamping plate 506 is hinged to the end of the hinge rod 508 away from the fixing rod 505 by a pin. Elastic rubber 5010 is fixedly installed between the top clamping plates 506 and in the gaps between the top clamping plates 506 and the piston cylinder 502 and the bottom plate 507. High-pressure air is introduced into and discharged from the piston cylinder 502 to control the downward and upward movement of the piston 503. When the piston 503 moves downward, the gas in the space below the piston 503 is compressed, which in turn pushes the elastic rubber 5010 to expand. While the elastic rubber 5010 expands, it drives the top clamping plate 506 to move outward, so that the top clamping plate 506 can press against the inner wall of the blade center hole, so that the blade can move along with the movement of the clamping fixture 5. A hinge rod 508 is provided to guide the top clamping plate 506 and prevent the top clamping plate 506 from shifting.

[0040] Four clamping plates 506 are provided and are arranged in a circumferential array about the central axis of the piston cylinder 502. Anti-slip texture is provided on the outer surface of the clamping plates 506. The four clamping plates 506 can increase the number of contact points with the inner wall of the center hole of the belt. The anti-slip texture can also increase the friction between the clamping plates 506 and the blade, further improving the stability of the clamping effect.

[0041] A push rod 5011 is fixedly installed at the bottom of the piston 503. Multiple push rods 5011 are provided, and each corresponds to a hinge rod 508. When the piston 503 moves down, it can drive the push rod 5011 to move down synchronously. The push rod 5011 pushes the hinge rod 508 to ensure that when the top plate 506 presses against the inner wall of the blade, the push rod 5011 presses against the hinge rod 508, thus preventing the top plate 506 from being retracted by force.

[0042] The tooling installation component 4 includes a connecting frame 401. An electric slide rail 402 is fixedly installed at the bottom of the connecting frame 401. A movable frame 403 is fixedly installed at the movable end of the electric slide rail 402. An adjustable connecting component 404 is provided at the bottom of the movable frame 403. The adjustable connecting component 404 connects the movable frame 403 and the mounting base 501. The connecting frame 401 is used to install the electric slide rail 402. The electric slide rail 402 is used to adjust the position of the movable frame 403, thereby adjusting the position of the mounting base 501 connected to the movable frame 403, and then adjusting the position of the piston cylinder 502 and other structures connected to the mounting base 501.

[0043] The electric slide rail 402 is provided with two sets, left and right. The bottom of the connecting frame 401 is provided with an auxiliary slide rail. The front end of the moving frame 403 is fixedly connected to the movable end of the electric slide rail 402, and the rear end of the moving frame 403 is fixedly connected to the movable end of the auxiliary slide rail. The two sets of electric slide rails 402 are used to connect the two sets of moving frames 403. A clamping fixture 5 for clamping the blade is added. The auxiliary slide rail is provided to support and guide the moving frame 403 to prevent the moving frame 403 from shifting position during the adjustment process.

[0044] The adjustable connecting component 404 includes a connecting plate 4041 and a mounting plate 4043. The connecting plate 4041 is fixedly installed at the bottom of the movable frame 403. The outer wall of the connecting plate 4041 has a mounting groove 4042. A connecting bolt 4045 passes through the mounting groove 4042 and passes through the mounting plate 4043. Both ends of the connecting bolt 4045 are threaded with fixing nuts 4044. The bottom end of the mounting plate 4043 is fixedly connected to the top of the mounting base 501. A clamping plate 7 is slidably sleeved on the connecting bolt 4045. The clamping plate 7 is located at the fixed position. There are two connecting bolts 4045 connecting the nut 4044 and the connecting plate 4041, and on the same mounting plate 4043. By adjusting the position of the mounting plate 4043 relative to the mounting groove 4042, the position of the mounting seat 501 can be adjusted. Since there are two connecting bolts 4045 on the mounting plate 4043, the problem of rotation of the mounting plate 4043 relative to the connecting plate 4041 can be effectively avoided. The clamping plate 7 can also increase the friction between the fixing nut 4044 and the connecting plate 4041, thereby increasing the installation firmness of the mounting plate 4043.

[0045] The three-axis adjustment assembly 3 includes a dual-axis moving platform 301. The movable end of the dual-axis moving platform 301 is fixedly connected to an electric turntable 302. The rotating end of the electric turntable 302 is fixedly connected to the connecting frame 401. The dual-axis moving platform 301 adjusts the electric turntable 302 in both X and Y axes, thereby adjusting the tooling installation assembly 4 in both X and Y axes, and then adjusting the clamping tooling 5 in both X and Y axes. The electric turntable 302 drives the tooling installation assembly 4 to rotate a certain angle, thereby achieving the purpose of adjusting the angle of the clamping tooling 5.

[0046] The electric lifting assembly 2 includes an electric lifting slide rail 201, which is vertically arranged. A lifting plate 202 is fixedly connected to the movable end of the electric lifting slide rail 201. The bottom front end of the lifting plate 202 is fixedly connected to the fixed end of the dual-axis moving platform 301. The electric lifting slide rail 201 drives the lifting plate 202 to rise and fall, which in turn drives the three-axis adjustment assembly 3 to rise and fall. The rise and fall of the three-axis adjustment assembly 3 drives the tooling installation assembly 4 to rise and fall, which in turn drives the clamping tooling 5 to rise and fall, so that the clamping tooling 5 can remove the blade from the placement frame or the conveyor belt.

[0047] The rotating assembly 1 includes an electric turntable 101. Multiple mounting holes 103 are provided on the rotating end of the electric turntable 101. The bottom end of the electric lifting slide rail 201 is fixedly connected to the rotating end of the electric turntable 101 via bolts matching the mounting holes 103. A mounting plate 102 is fixedly provided at the bottom of the electric turntable 101. Because there are multiple mounting holes 103, the position of the electric lifting assembly 2 relative to the rotating end of the electric turntable 101 can be adjusted, thereby adjusting the range of items to be picked up and placed. The electric turntable 101 drives the electric lifting assembly 2 to rotate half a revolution, which in turn drives the three-axis adjustment assembly 3 to rotate half a revolution. The movement of the three-axis adjustment assembly 3 drives the tooling installation assembly 4 to move, which in turn drives the clamping tooling 5 to move, used to pick up and place the blade from the placement frame or conveyor belt to another location.

[0048] A positioning sensor 8 is fixedly installed on the mounting base 501, and a signal transceiver 10 is fixedly installed on the top of the connecting plate 4041. The signal transceiver 10 is electrically connected to the positioning sensor 8. Solenoid valves 9 are provided at both the air inlet and air outlet ports of the piston cylinder 502. The position of the blade is located by the positioning sensor 8, and the air inlet and outlet of the mounting base 501 are controlled by the solenoid valves 9. The signal transceiver 10 is used to transmit the positioning data of the positioning sensor 8 to the workshop control equipment.

[0049] Working Principle: During use, the blades are conveyed to the clamping area by a conveyor belt, or the blades are placed in the placement frame (as shown in the rotating assembly 1), and then conveyed to the clamping area by the conveyor belt. Based on the blade placement interval, the position of the clamping fixture 5 is adjusted by the three-axis adjustment assembly 3 and the tooling installation assembly 4 to match the blade position. Then, the electric lifting assembly 2 drives the three-axis adjustment assembly 3 to move downwards, which in turn drives the tooling installation assembly 4 to move downwards. The downward movement of the tooling installation assembly 4 drives the clamping fixture 5 to move downwards, allowing the base plate 507 inside the clamping fixture 5 to pass through the center hole of the blade until the base plate 507 touches the bottom. Then, the solenoid valve 9 of the air inlet pipe of the piston cylinder 502 is opened, allowing high-pressure gas to enter the piston cylinder 502, which then pushes the piston 503 downwards. The gas in the space below the piston 503 is compressed, which in turn pushes the elastic rubber 5010 to expand. While expanding, the top clamping plate 506 moves outward, allowing it to press against the inner wall of the blade's central hole. This allows the blade to move along with the clamping fixture 5. Then, the solenoid valve 9 on the air inlet pipe of the piston cylinder 502 is closed again, and the electric lifting assembly 2 is activated to raise the three-axis adjustment assembly 3, which in turn raises the fixture installation assembly 4. The rise of the fixture installation assembly 4 raises the clamping fixture 5, which in turn raises the blade. The blade is then removed. The electric turntable 101 is activated to rotate the electric lifting assembly 2, causing the clamping fixture 5 to be rotated to another position. Then, the solenoid valve 9 on the exhaust pipe of the piston cylinder 502 is opened to extract the high-pressure gas from the piston cylinder 502. This causes the piston 503 to move upward under the pressure difference. As the piston 503 moves upward, the elastic rubber 5010 retracts, causing the top clamping plate 506 to retract, separating the top clamping plate 506 from the blade, allowing the blade to be released.

[0050] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
