Description

Technical Field

[0001] The invention relates to the technical field of cemented carbide tool bit processing, in particular to a cemented carbide tool bit performance detection device. Background Art

[0002] Carbide tool heads are a type of tool made of carbides such as tungsten carbide and titanium carbide. They have the characteristics of high hardness, good wear resistance, and excellent heat resistance. They are usually used in lathes, milling machines, drilling machines and other machine tools for cutting, drilling, milling and other operations. Because carbide tool heads are subject to various forces in actual use, and friction will also occur between the tool and the workpiece, causing the tool surface to gradually wear. Therefore, it is necessary to conduct bending strength tests and wear resistance tests on carbide tool heads to evaluate the tool material's ability to resist bending deformation and fracture, as well as its ability to resist wear, to ensure the quality and service life of carbide tool heads.

[0003] The common bending strength test is to place the sample in the testing machine, support the two ends of the sample with supports, and use the downward pressure head to press the middle of the sample until the sample breaks. The bending strength is expressed by the pressure the sample bears when it breaks. The wear resistance test uses a friction wheel to rub the working end of the sample, and the wear resistance is expressed by the reduction in the length or mass of the sample, which evaluates the service life of the alloy cutter head.

[0004] When the above-mentioned detection method is used to detect the carbide cutter head, the wear resistance test and the bending strength test are carried out separately. Before performing the two tests, the alloy cutter head needs to be fixed. The repeated fixing operation takes a long time, which affects the efficiency of the detection. When the wear resistance test is performed on the alloy cutter head, the end of the alloy cutter head in contact with the friction wheel only relies on the pressure to resist each other, and the friction wheel has no additional auxiliary guide limit. When the friction wheel is rubbed, there will be a relative offset between the alloy cutter head and the friction wheel, which will affect the accuracy of the wear resistance test. When the bending strength test is performed on the alloy cutter head, the alloy cutter head is placed on a bottom support seat with an arc groove. As the downward pressure on the middle part of the alloy cutter head gradually increases, the middle part of the alloy cutter head will gradually bend downward, and the two ends of the alloy cutter head will gradually warp upward, and the contact area between the end and the arc groove will decrease, and even break away from the limit of the arc groove. At this time, the overall stability of the alloy cutter head decreases and it is easy to offset, which will affect the accuracy of the bending strength test. Summary of the invention

A movable plate 132 located between the two fixing plates 131 and having a through hole in the middle is slidably installed on the top of the base 11. A clamping component 135 is installed on the opposite side of the movable plate 132 and the right fixing plate 131.

[0032] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The wear-resistant detection mechanism 2 includes a pushing plate 21 which is slidably installed on the top of the base 11 and is located on the left side of the movable plate 132. A driving motor 22 is fixedly installed on the right side of the pushing plate 21. A hydraulic push rod 23 for pushing the pushing plate 21 to move is fixedly installed on the left fixed plate 131.

[0033] See also Figure 1 , Figure 2 and Figure 8 The bending resistance detection mechanism 3 includes a gantry 31 fixedly mounted on the base 11, a hydraulic push rod 2 32 is fixedly mounted on the horizontal section of the gantry 31, a mounting seat 33 is fixedly connected to the bottom of the output shaft of the hydraulic push rod 2 32, a pressure sensor for measuring the downward pressure is also installed on the pushing section of the hydraulic push rod 2 32, a downward pressure head 34 is fixedly connected to the bottom of the mounting seat 33, and a group of elastic telescopic rods 2 35 are hinged on both sides of the mounting seat 33. The number of each group of elastic telescopic rods 2 35 is two, and a locking assembly 36 for locking the clamping component 135 is installed at one end of the two elastic telescopic rods 2 35 of the same group away from the mounting seat 33. It should be noted that the pressure sensor is connected to an external computer, and the pressure data applied by the hydraulic push rod 2 32 is transmitted to the computer in real time through the pressure sensor, and the pressure data is analyzed and displayed by the computer.

[0034] See also Figure 1 and Figure 2 There are two supports 12 and they are distributed between the left and right clamping parts 135 . The top of the support 12 is provided with an arc-shaped groove that is concave downward.

[0035] The support 12 is used to support the alloy cutter head. The arc-shaped groove on the top of the support 12 can prevent the alloy cutter head from rolling down from the front and rear sides of the support 12, so that the left and right ends of the alloy cutter head are horizontally aligned with the center line of the clamping component 135, making it easier for the clamping component 135 to clamp the alloy cutter head.

[0036] See also Figure 1 , Figure 2 and Figure 4 , guide rods 1311 are fixedly connected between the four corners of the left and right fixed plates 131, the movable plate 132 and the pushing plate 21 are slidably installed between the four guide rods 1311, the right side of the pushing section of the hydraulic push rod 23 is fixedly connected to the left side of the pushing plate 21, and an electric push rod 136 for pushing the movable plate 132 is fixedly installed on the base 11, and the right side of the pushing section of the electric push rod 136 is fixedly connected to the bottom of the movable plate 132.

[0037] See also Figure 1 and Figure 3 A baffle 133 for shielding the left end of the through hole is installed on the left side of the movable plate 132 for sliding back and forth. A moving component 134 for driving the baffle 133 to move back and forth is also installed on the left side of the movable plate 132. The moving component 134 includes an elastic telescopic rod 1341 fixedly connected to the left side of the movable plate 132 and symmetrically distributed about the through hole. A linkage rod 1342 is hinged between the left side of the telescopic section of the elastic telescopic rod 1341 and the front end of the baffle 133. A guide rod 1343 symmetrically distributed about the through hole is fixedly connected to the left side of the movable plate 132.

A return spring 1344 is fixedly connected between the rear side of the baffle 133 and the inner wall of the movable plate 132.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The movement of the pushing plate 21 and the movable plate 132 is guided by the guide rod 1311 to improve the stability of the movement of the pushing plate 21 and the movable plate 132. The movable plate 132 is pushed to the right by the electric push rod 136, and the left end of the alloy cutter head enters the through hole. The baffle plate 133 is used to push the alloy cutter head to the right until the baffle plate 133 and the fixed plate 131 on the right limit the left and right positions of the alloy cutter head, and then the clamping component 135 is controlled to clamp the left and right ends of the alloy cutter head to improve the stability of the alloy cutter head during detection.

[0039] Then, the hydraulic push rod 23 pushes the pushing plate 21 to move to the right, and the pushing plate 21 drives the driving motor 22 and the connecting plate 24 to move to the right together. The pushing plate 21 pushes the telescopic section of the elastic telescopic rod 1341 to move to the right. When the telescopic section of the elastic telescopic rod 1341 moves to the right, it pushes the baffle 133 to move forward through the linkage rod 1342. At this time, the return spring 1344 will be stretched, and the guide rod 1343 guides the baffle 133 to improve the stability of the movement of the baffle 133. When the forward-moving baffle 133 no longer blocks the through hole, the connecting plate 24 can enter the through hole to perform a wear resistance test on the left end of the alloy cutter head.

[0040] After the detection is completed, the hydraulic push rod 23 drives the pushing plate 21 to move to the left. After the pushing of the pushing plate 21 is lost, the rebound force of the reset spring 1344 is used to pull the baffle 133 to move backward. At the same time, the telescopic section of the elastic telescopic rod 1341 drives the rear end of the linkage rod 1342 to move to the left, so that the baffle 133 covers the through hole again.

[0042] See also Figure 4 , Figure 5 and Figure 6 The clamping component 252 includes a wedge-shaped clamping block 2521 slidably installed along the radial direction of the hollow ring 251, and a ball is rotatably installed on one end of the wedge-shaped clamping block 2521 close to the center of the hollow ring 251. An inner groove is opened on the right side of the wedge-shaped clamping block 2521, and a baffle plate 2522 located in the inner groove is fixedly connected to the right inner wall of the hollow ring 251. A return spring 2523 is fixedly connected between the side of the baffle plate 2522 away from the center of the hollow ring 251 and the inner wall of the wedge-shaped clamping block 2521, and the right end of the pushing rod 253 is slidably matched with the inclined surface of the end of the wedge-shaped clamping block 2521 away from the center of the hollow ring 251.

[0043] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Before the hydraulic push rod 23 pushes the pushing plate 21, the driving motor 22 and the connecting disk 24 to move to the right, the driving motor 22 drives the pushing rod 253 to rotate to a state of up and down front and back distribution (positive cross distribution). At this time, the pushing rod 253 is aligned with the socket on the left side of the hollow ring 251, and then the hydraulic push rod 23 pushes the pushing plate 21, the driving motor 22 and the connecting disk 24 to move to the right, so that the right end of the pushing rod 253 is inserted into the socket and contacts the inclined surface of the wedge-shaped clamping block 2521. The pushing rod 253 is used to push the wedge-shaped clamping block 2521 to move toward the center of the hollow ring 251 until the ball on the wedge-shaped clamping block 2521 is clamped on the outside of the alloy cutter head working section (i.e., the wear-resistant detection section), and the reset spring 2 2523 will be compressed.

[0044] See also Figure 4 , Figure 5 and Figure 6 The connecting component 254 includes a plurality of limit rods 2541 which are slidably installed along the radial direction of the hollow ring 251 and are evenly distributed in the circumferential direction. The limit rods 2541 are located on the outer side of the corresponding pushing rods 253. A hole groove is provided on the hollow ring 251 for sliding one end of the limit rod 2541 away from the center of the hollow ring 251. A slot is provided on the inner wall of the through hole for plugging and matching with the end of the limit rod 2541 away from the center of the hollow ring 251. A limit block 2542 is slidably installed on one end of the limit rod 2541 close to the center of the hollow ring 251. Teeth and tooth grooves are respectively installed on the opposite sides of the limit block 2542 and the corresponding pushing rod 253. The teeth and tooth grooves cooperate with each other. A reset spring 2543 is fixedly connected between the limit block 2542 and the limit rod 2541. A transposition component for driving the limit rod 2541 to transpose is also installed on the hollow ring 251.

[0045] See also Figure 4 , Figure 5 , Figure 6 and Figure 7The transposition component includes a guide block 2544 rotatably connected to the right end of the limiting rod 2541, a rotating ring 2545 located on the right side of the limiting rod 2541 is rotatably installed inside the hollow ring 251, a plurality of arc-shaped through grooves 2546 evenly distributed in the circumferential direction are opened on the rotating ring 2545, and the guide block 2544 slides in cooperation with the arc-shaped through grooves 2546 one by one, a pushing rod 2547 is fixedly connected to the right side of the rotating ring 2545, and a movable groove for the pushing rod 2547 to deflect is opened on the right side of the hollow ring 251, and the right end of the pushing rod 2547 passes through the movable groove and is fixedly connected to a positioning plate located on the right side of the hollow ring 251, and a fixing bolt 2548 is fixedly connected to the positioning plate, and two fixing holes 2549 threadedly matched with the fixing bolt 2548 are opened on the right side of the hollow ring 251. When the pushing rod 2547 rotates to one end of the movable groove, the fixing bolt 2548 is just coaxially aligned with one of the fixing holes 2549.

[0046] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 When the push rod 253 pushes the wedge-shaped clamping block 2521 to clamp the alloy cutter head, the fixing bolt 2548 is loosened, and then the push rod 2547 is pushed to drive the rotating ring 2545 to rotate clockwise, so that the arc-shaped through groove 2546 pushes the guide block 2544 and the limit rod 2541 to move toward the center of the hollow ring 251, so that the limit block 2542 and the corresponding pushing rod 253 are engaged with each other through the tooth groove, and the pushing rod 253 is connected with the hollow ring 251. At this time, the limit rod 2541 is not completely separated from the clamping groove to prevent the hollow ring 251 from moving during the transposition and locking process.

[0047] Afterwards, the rotating ring 2545 pushes the guide block 2544 and the limiting rod 2541 to continue to move toward the center of the hollow ring 251, so that the limiting rod 2541 is completely separated from the slot. At this time, the reset spring three 2543 will be compressed. When the pushing rod 2547 moves to the bottom end of the movable slot, the fixing bolt 2548 is coaxially aligned with another fixing hole 2549, and then the fixing bolt 2548 and the fixing hole 2549 are tightened together to position the rotating ring 2545.

[0048] Before the wear resistance test, the initial length of the alloy cutter head is measured using an existing laser measuring instrument. When the wear resistance test is performed, the connecting disk 24 is driven to rotate by the driving motor 22, so that the friction block 241 rubs the left end of the alloy cutter head. During the friction process, the hydraulic push rod 23 pushes the connecting disk 24 and the friction block 241 to move to the right, so that the friction block 241 and the alloy cutter head are kept in a pressed state. When the connecting disk 24 moves to the right, it will drive the pushing rod 253 and the hollow ring 251 to move to the right together. During the rotation of the connecting disk 24, the pushing rod 253 will drive the hollow ring 251 to rotate, and the wedge-shaped clamping block 2521 and the ball thereon will always clamp the alloy cutter head. The connecting disk 24 is limited by the linkage cooperation of the hollow ring 251, the wedge-shaped clamping block 2521 and the pushing rod 253, while maintaining the support for the alloy cutter head detection section, thereby improving the relative stability of the friction block 241 and the alloy cutter head during friction, thereby improving the accuracy of the detection.

[0049] After a period of time, the friction on the alloy cutter head is stopped, and then the hydraulic push rod 23 drives the pushing plate 21 to move to the left, and the pushing plate 21 drives the driving motor 22, the connecting plate 24 and the hollow ring 251 to move to the left together. When the hollow ring 251 moves to the left to the initial position, the driving motor 22 drives the connecting plate 24 and the hollow ring 251 to rotate, so that the wedge-shaped clamping block 2521 is in a state of vertical front and rear distribution (positive cross distribution). At this time, the limit rod 2541 is aligned with the card slot up and down, and then the fixing bolt 2548 is loosened, and then the push rod 2547 is pushed to drive the rotating ring 2545 to rotate counterclockwise, so that the rotating ring 254 The limiting rod 2541 is pushed to move away from the center of the hollow ring 251, so that the limiting rod 2541 is inserted into the slot until the limiting block 2542 is separated from the pushing rod 253, and then the hydraulic push rod 1 23 drives the pushing plate 21 to continue to move leftward, so that the pushing rod 253 is completely separated from the hollow ring 251. At this time, the rebound force of the return spring 2 2523 is used to push the wedge-shaped clamping block 2521 to move away from the center of the hollow ring 251, so that the wedge-shaped clamping block 2521 releases the clamping of the alloy cutter head, and then the existing laser measuring instrument is used to measure the length of the alloy cutter head after friction to evaluate the wear resistance of the alloy cutter head.

[0050] See also Figure 1 , Figure 2 , Figure 8 and Fig. 9The clamping component 135 is a three-jaw chuck, and the locking assembly 36 includes a locking block 361 that is slidably mounted on the top of the base 11 and is located between the adjacent clamping components 135 and the support 12. The locking block 361 has a Y-shaped structure, and a pin rod 363 is fixedly connected to the clamping claw of the clamping component 135. The locking block 361 is provided with a plurality of pin holes 362 that are plugged into and matched with the pin rod 363 one by one. A connecting rod 364 is hinged at one end of the top of the locking block 361, and a fastening bolt 365 is threadedly connected to the end of the connecting rod 364 away from the locking block 361. The connecting rod 364 is connected and locked to the other end of the top of the locking block 361 through the fastening bolt 365.

[0051] See also Figure 1 and Fig. 9 The top of the mounting seat 33 is fixedly connected to a guide rod 331 symmetrically distributed front and rear about the hydraulic push rod 32 , and the guide rod 331 is connected to the gantry 31 for sliding up and down.

[0052] See also Figure 1 , Figure 2 , Figure 8 and Fig. 9 Before placing the alloy cutter head on the support 12, the connecting rod 364 is in an open state, so that the alloy cutter head can be moved downward from the opening between the two ends of the top of the locking block 361 and placed on the support 12, and then the connecting rod 364 is rotated to close the opening between the two ends of the top of the locking block 361, and then the connecting rod 364 is connected to the other end of the locking block 361 using the fastening bolt 365. The connecting rod 364 can improve the firmness of the connection of the locking block 361.

[0053] When conducting anti-bending test, the mounting seat 33 and the pressing head 34 are pushed downward by the hydraulic push rod 32, and the guide rod 331 guides the mounting seat 33 to improve the stability of the up and down movement of the mounting seat 33. During the downward movement of the mounting seat 33, the locking block 361 is pushed by the elastic telescopic rod 35 to move toward the direction of the corresponding clamping component 135 until the locking block 361 contacts the claw of the clamping component 135. At this time, the pin rod 363 is just plugged into the pin hole 362, and the three claws are connected together by the locking block 361 to improve the firmness of the claws to fix the alloy tool head.

[0054] Afterwards, the mounting seat 33 pushes the pressing head 34 to continue to move downward. At this time, the elastic telescopic rod 35 can support and guide the mounting seat 33, further improving the stability of the downward movement of the mounting seat 33 and the pressing head 34. The pressing head 34 is used to press the middle part of the alloy cutter head until the alloy cutter head is deformed. The pressure sensor is used to measure the maximum pressure on the alloy cutter head when it breaks, and the bending strength of the alloy cutter head is obtained.
