Description

Technical Field

[0001] The invention relates to the technical field of heat treatment of shaft parts, in particular to intelligent heat treatment equipment for processing transmission shafts. Background Art

[0002] The transmission shaft is an indispensable part in the work of various mechanical equipment. Before installation, it needs high-frequency quenching to improve the mechanical properties. The quenching method generally adopts a method of heating the shaft through a high-frequency coil and then rapidly cooling it through the coolant sprayed by the water spray ring. There is a shaft quenching equipment with a relatively simple structure. During the specific work, the staff only needs to pass the shaft through the high-frequency coil and insert it into a hollow support plate, use the groove of the hollow support plate to position the shaft, and then start the equipment. At the same time, the lifting assembly is used to drive the hollow support plate downward, and then drive the shaft to quench. Although this loading method is simple and convenient to operate and has high processing efficiency, in the specific use process, we found that inserting the shaft into the hollow support plate in advance to fix the shaft will cause one end of the shaft to be blocked by the hollow support plate. Therefore, when the shaft is processed once, one end of it cannot be quenched, and subsequent processing is required, which is also troublesome. For this reason, we propose an intelligent heat treatment equipment for transmission shaft processing. Summary of the invention

[0041] The limiting ring 5 is arranged on the support frame 1 and is located above the high-frequency coil 11. The shaft body passes through the limiting ring 5 and is located on the top rod 4. In a certain distance of the initial movement of the sliding plate 2, the limiting ring 5 cooperates with the top rod 4 to limit the shaft body, and the limiting ring 5 and the top rod 4 are quenched.

[0042] The linkage assembly 6 is arranged on the sliding plate 2 and connected to the push rod 4. In the process of moving the sliding plate 2, the linkage assembly 6 is used to drive the push rod 4 to move downward relative to the hollow support plate 13, and at the same time, the shaft body is inserted into the hollow support plate 13 by its own gravity;

[0043] During specific use: after the staff passes the shaft through the limiting ring 5 and the high-frequency coil 11 in turn, the staff uses the push rod 4 to support the end of the shaft, and limits the shaft through the limiting ring 5 and the push rod 4, and at the same time, the bottom end of the shaft is completely located in the high-frequency coil 11, and then the device body is started. During a period of time when the shaft is initially moved, the limiting ring 5 and the push rod 4 are used to limit the shaft, and the bottom end of the shaft is quenched. When the middle part of the shaft is quenched, the push rod 4 is driven to move and retract into the hollow support plate 13, and at the same time, the bottom end of the shaft is inserted into the hollow support plate 13 to limit the shaft, and the shaft continues to be moved to drive the limiting ring 5 to expand, so that when the sliding plate 2 is moved in the opposite direction to discharge the material, the quenched shaft is prevented from contacting the inner wall of the limiting ring 5, thereby preventing impurities from contaminating the limiting ring 5.

[0044] The lifting assembly 3 includes a guide rod 31 fixedly connected to the support frame 1, the guide rod 31 slides through one end of the sliding plate 2, the support frame 1 is rotatably connected to a shaft 32 through a bearing, the shaft 32 is fixedly connected to a screw 33, the screw 33 passes through the sliding plate 2 and is threadedly connected thereto, and the support frame 1 is fixedly connected to a drive motor 34, the output shaft of the drive motor 34 is fixedly connected to the shaft 32, and the drive motor 34 is started to drive the shaft 32 to rotate, thereby driving the screw 33 to rotate, thereby driving the sliding plate 2 to move along the guide rod 31.

[0045] The linkage assembly 6 includes a strip plate 35 slidably connected to the sliding plate 2, a connecting rod 36 is rotatably connected between the strip plate 35 and the top rod 4 through a rotating shaft, and a spring 37 is sleeved on the top rod 4, one end of which contacts and abuts against the inner wall of the hollow support plate 13. In the process of moving the strip plate 35, the connecting rod 36 is driven to move, thereby driving the top rod 4 to move, and at the same time, the spring 37 is compressed and contracted to provide a self-restoring elastic force for it;

[0046] A rectangular plate 38 is fixedly connected to the support frame 1, one end of the strip plate 35 passes through the sliding plate 2 and is provided with a cylinder 39, a guide groove 40 is opened on the rectangular plate 38, one end of the cylinder 39 is located in the guide groove 40, and in the process of moving the sliding plate 2, the cylinder 39 is driven to slide along the guide groove 40 to drive the strip plate 35 to move.

[0047] The guide groove member 40 includes a straight groove 41 provided on the rectangular plate 38. One end of the cylinder 39 is located in the straight groove 41 and is slidably connected to the inner wall thereof. In the process of moving the sliding plate 2, the cylinder 39 is driven to slide along the straight groove 41 to keep the strip plate 35 stationary relative to the sliding plate 2. At this time, the bottom end of the shaft body is quenched.

[0048] The rectangular plate 38 is provided with an inclined slide groove 42 which is connected to the straight slide groove 41. In the process of moving the sliding plate 2, the cylindrical body 39 is driven to disengage from the straight slide groove 41 and slide into the inclined slide groove 42. Then, the cylindrical body 39 slides along the inclined slide groove 42 to drive the strip plate 35 to move relative to the sliding plate 2. When the quenching of the bottom end of the shaft body is completed, the shaft body is continued to be moved, and the top rod 4 will move and retract to drive the end of the shaft body to be inserted into the hollow supporting plate 13, so as to further position the shaft body. Because when the shaft body is quenched to the top end, the shaft body will be completely separated from the limiting ring 5. At this time, the hollow supporting plate 13 can position the shaft body alone to ensure the stability of the shaft body during quenching.

[0049] A straight groove 2 43 connected to the inclined groove 1 42 is provided on the rectangular plate 38. In the process of moving the sliding plate 2, the cylinder 39 is driven to disengage from the inclined groove 1 42 and slide into the straight groove 2 43. The cylinder 39 slides along the straight groove 2 43 to keep the strip plate 35 stationary relative to the sliding plate 2. At this time, the shaft body will follow the hollow support plate 13 to move and quench.

[0050] The limit ring 5 adopts a symmetrical split design, which includes two semicircular rings 44, one side of the semicircular ring 44 is fixedly connected to a deflection plate 45, one end of the deflection plate 45 is fixedly connected to a second shaft 46, and a mounting plate 47 is fixedly connected to the support frame 1. The second shaft 46 and the mounting plate 47 are rotatably connected through a bearing, and a transmission member 48 is arranged between the second shaft 46 and the sliding plate 2. In the process of moving the sliding plate 2, after the push rod 4 is retracted to the hollow support plate 13, the sliding plate 2 continues to be moved, and the transmission member 48 is used to drive the second shaft 46 to rotate, so that the two semicircular rings 44 are deflected and opened to avoid the shaft body during discharging, and to avoid the shaft body after quenching from contacting the inner wall of the limit ring 5, thereby avoiding impurities from being contaminated on the limit ring 5, and then avoiding contamination of the shaft body in subsequent processing. The impurities here specifically refer to impurities such as those in the coolant attached to the surface of the shaft body after quenching.

[0051] The transmission member 48 includes a dial plate 49 fixedly connected to the second shaft 46, a push rod 51 is slidably connected to the mounting plate 47, one end of the push rod 51 is fixedly connected to a U-shaped plate 52, both ends of the U-shaped plate 52 are fixedly connected to the third shaft 53, a guide groove 54 is provided on the dial plate 49, one end of the third shaft 53 is located in the guide groove 54 and slidably connected to the inner wall thereof, and the moving push rod 51 drives the U-shaped plate 52 to move, thereby driving the dial plate 49 to deflect, and driving the second shaft 46 to rotate;

[0052] A slide post 1 55 and a slide post 2 56 are sequentially longitudinally slidably arranged on the support frame 1. A shaft 4 57 is fixedly connected to the slide post 1 55 and the slide post 2 56. A lever 1 58 is rotatably connected to the support frame 1 via a rotating shaft. Guide grooves 54 are also provided at both ends of the lever 1 58. The two shafts 4 57 are correspondingly located in the two guide grooves 54 and slidably connected to the inner walls thereof. When the slide post 1 55 is pushed, the lever 1 58 is driven to deflect, thereby driving the slide post 2 56 to move in the opposite direction of the slide post 1 55.

[0053] A squeezing plate 59 is fixedly connected to the sliding plate 2, and both sides of the squeezing plate 59 are designed with inclined surfaces. When the shaft body is in a state to be processed, one end of the sliding column 2 56 passes through the support frame 1, and the end of the sliding column 1 55 is located in the support frame 1. A synchronous part 61 is arranged between the sliding column 1 55 and the push rod 51. When quenching the workpiece, specifically in the process of moving the sliding plate 2 downward, the push rod 4 is driven to be retracted to the hollow support plate 13, and then the squeezing plate 59 is driven to squeeze the sliding column 2 56 to move and retract into the support frame 1, and the synchronous part 61 is used to drive the push rod 51 to move, and at the same time, one end of the sliding column 1 55 moves out of the support frame 1. Conversely, when the shaft body is quenched and discharged, the sliding plate 2 is moved upward, and the squeezing plate 59 is used to squeeze the sliding column 1 55 to move and retract into the support frame 1, and at the same time, one end of the sliding column 2 56 moves out of the support frame 1.

[0054] The synchronous member 61 includes a lever 2 62 rotatably connected to the support frame 1 through a rotating shaft. One end of the push rod 51 is also fixedly connected to the shaft 4 57. Both ends of the lever 2 62 are also provided with guide grooves 54. The shaft 4 57 on the push rod 51 and one end of the shaft 4 57 on the slide column 1 55 are correspondingly located in the two guide grooves 54 and slidably connected to the inner wall thereof. When the slide column 1 55 is moved, the lever 2 62 is driven to deflect, thereby driving the push rod 51 to move.

[0055] When the two deflection blocks 63 are rotated, a telescopic rod 64 is fixedly connected between the two deflection blocks 63. The telescopic rod 64 is sleeved with a spring 2 65 whose two ends are respectively in contact with the two deflection blocks 63 and resist each other. When the angle between the telescopic rod 64 and the slide post 1 55 is less than ninety degrees, the spring 2 65 is in a compressed state to temporarily lock the slide post 1 55. In the process of moving the slide post 1 55, the angle between the telescopic rod 64 and the slide post 1 55 changes from an acute angle to a right angle and then to an acute angle. Specifically, when the extrusion plate 59 moves to push the slide post 1 55 to move, the telescopic rod 64 deflects, and the angle between it and the slide post 1 55 changes from an acute angle to a right angle and then to an acute angle. When it is reflected on the spring 2 65, the spring 2 65 is first compressed and then released, thereby achieving the temporary locking of the slide post 1 55 in two states, and also the temporary locking of the limit ring 5 in two states, thereby improving the stability of the device.

[0056] One end of the strip plate 35 is fixedly connected to a hollow cylinder 66, one end of the cylinder 39 is located in the hollow cylinder 66 and is fixedly connected to a spring three 67 having one end fixedly connected to the inner wall of the hollow cylinder 66, the inclined slide groove 1 42 is designed to have a shallower depth than the straight slide groove 1 41 and the straight slide groove 2 43, and a guide slope 68 is provided in the inclined slide groove 1 42. In the process of moving the sliding plate 2, the cylinder 39 is driven to slide along the guide slope 68, and at the same time, the spring three 67 is compressed to continue to move the sliding plate 2 until the cylinder 39 is separated from the inclined slide groove 1 42 and slides into the straight slide groove 2 43, and at the same time, the spring three 67 is reset to drive the cylinder 39 to extend and embed into the straight slide groove 2 43. Specifically, when the shaft body is quenched, that is, in the process of moving the sliding plate 2 downward, the cylinder 39 will slide along the straight slide groove 1 41, the inclined slide groove 1 42, and the straight slide groove 2 43 in sequence, thereby completing the shaft body. Quenching. On the contrary, when quenching is completed, that is, when the sliding plate 2 is moved up to discharge the material, the cylinder 39 will only move along the straight slide groove 2 43, so that when the shaft body moves up to discharge the material, its bottom end is always located in the hollow support plate 13, because the limit ring 5 is in an open state at this time. When the sliding plate 2 moves up to a distance from the initial position, the staff will take out the quenched shaft body, and then continue to move the sliding plate 2 to the top, and at the same time, the extrusion plate 59 squeezes and pushes the slide column 1 55 to move, so as to drive the two semicircular rings 44 to engage, and at the same time, the cylinder 39 slides along the straight slide groove 3 69, and after crossing the right-angled trapezoidal block 71, it is inserted into the straight slide groove 1 41. At this time, the push rod 4 extends out of the hollow support plate 13 again and returns to the initial state to meet the next shaft body quenching. The power for the cylinder 39 to move along the straight slide groove 3 69 comes from the spring 1 37 compressed when the push rod 4 is retracted into the hollow support plate 13.

[0057] A straight slide groove three 69 is provided on the rectangular plate 38, and the two ends of the straight slide groove three 69 are respectively connected to the straight slide groove one 41 and the straight slide groove two 43, and a right-angled trapezoidal block 71 is fixedly connected to the straight slide groove three 69 at the joint with the straight slide groove one 41. When the spring one 37 is reset to drive the cylinder 39 to slide along the straight slide groove three 69, the inclined surface of the right-angled trapezoidal block 71 is used to squeeze the cylinder 39 and compress the spring three 67 at the same time. When the cylinder 39 passes the right-angled trapezoidal block 71, the spring three 67 is reset to drive the cylinder 39 to insert into the straight slide groove one 41, thereby preventing the cylinder 39 from being stuck in the straight slide groove three 69 when the sliding plate 2 moves downward, thereby improving the smoothness of the device during operation.
