Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear heat treatment deformation correction device. Background Technology

[0002] Gears are mainly made of steel. After heat treatment, the toughness of steel decreases as the temperature increases. If the local stress on the gear can no longer be affected by heat, the gear will deform. When the gear is heat treated, if the heating rate is too fast, the surface of the gear will heat up too quickly, while the temperature inside the gear will rise relatively slowly. If there is a temperature difference between the surface and the inside, the gear will deform irregularly.

[0003] When straightening gears, it is usually necessary to heat the gears first before the straightening operation. During the heating process, the high-temperature flame sprayed by the spray gun enables the gears to be heated quickly and evenly. At the same time, in order to ensure the stability of the heating and straightening process, the gears need to be clamped. However, in actual production, the gears that need to be straightened are of different sizes, and it is very troublesome to select appropriate clamps according to different gear sizes, which affects work efficiency. In view of this technical problem, this application proposes a gear heat treatment deformation correction device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gear heat treatment deformation correction device. This device involves fitting a gear onto four clamping ring blocks, activating a servo motor to slide the clamping ring blocks, and adjusting the spacing of the four clamping ring blocks to accommodate different gear inner diameters. After the gear is fixed in place, a blowtorch is used to heat the gear before correction, thus improving work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gear heat treatment deformation correction device includes an operating table. A fireproof plate is fixedly connected to the top of the operating table, and a flame gun is fixedly connected to the right side of the fireproof plate. A support plate is fixedly connected to the top of the operating table, and a support rod is fixedly connected to the front side of the support plate. Four grooves are formed on the outer wall of the support rod. Limiting sliders are slidably connected to the left and right sides of the inner wall of each groove. Clamping ring blocks are fixedly connected to the adjacent side of two of the limiting sliders. The inner walls of the four clamping ring blocks are connected by an adjusting component to adjust the spacing between the four clamping ring blocks. Two connecting slots are formed at the bottom of the operating table, and two connecting sliders are slidably connected to the inner walls of each connecting slot. A collection box is fixedly connected to the bottom of the four connecting sliders. The front sides of the two connecting sliders are connected by a limiting component to limit the movement of the collection box.

[0007] Furthermore, the adjusting assembly includes a threaded rod rotatably connected to the inner wall of the groove, the outer wall of the threaded rod being threadedly connected to the inner wall of the clamping ring block, and a second bevel gear being fixedly connected to one end of each of the four threaded rods.

[0008] Furthermore, an adjusting rod is rotatably connected to the inner wall of the support rod, and a first bevel gear is fixedly connected to the front end of the adjusting rod. The outer wall of the second bevel gear meshes with the outer walls of four second bevel gears.

[0009] Furthermore, a servo motor is fixedly connected to the rear end of the support plate, and the rear end of the adjusting rod is fixedly connected to the drive end of the servo motor.

[0010] Furthermore, the limiting component includes a limiting block slidably connected to the bottom side of the operating table, the front side of the connecting slider abuts against the rear side of the limiting block, the outer wall of the connecting slider slidably connected to the inner wall of the limiting block, and an adjusting rack fixedly connected to the left side of the limiting block, and an adjusting gear meshing with the left side of the adjusting rack.

[0011] Furthermore, an adjustment knob is rotatably connected to the front side of the operating panel, and the front end of the adjustment gear is fixedly connected to the rear end of the adjustment knob.

[0012] Furthermore, a support block is fixedly connected to the front side of the fireproof board, and the top of the support block abuts against the outer wall of the flamethrower.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by fitting the gear onto four clamping ring blocks, the servo motor is activated to make the clamping ring blocks slide, and the spacing of the four clamping ring blocks is adjusted to accommodate different gear inner diameters to clamp the gear. After the gear is fixed, a blowtorch is activated to heat the gear before straightening, which speeds up the work efficiency.

[0015] 2. In this utility model, the gears damaged during the correction process are collected. When the collection box is almost full, the adjustment knob is turned to make the adjustment gear rotate. The rotation of the adjustment gear meshes with the adjustment rack, which drives the adjustment rack to slide and the limit block slides up. The fixing of the connecting slider is released, and the second bevel gear is removed from the operating table and tilted. Attached Figure Description

[0024] Reference Figures 1-3This utility model provides an embodiment of a gear heat treatment deformation correction device, comprising an operating table 1, a fireproof plate 5 fixedly connected to the top of the operating table 1, and a flame gun 7 fixedly connected to the right side of the fireproof plate 5. The flame gun 7 is activated to heat the gear before correction. A support plate 2 is fixedly connected to the top of the operating table 1, and a support rod 3 is fixedly connected to the front side of the support plate 2. Four grooves are formed on the outer wall of the support rod 3, and limit sliders 13 are slidably connected to the left and right sides of the inner wall of each groove to prevent clamping ring blocks 9 from sliding out of the groove. Clamping ring blocks 9 are fixedly connected to the side of the two limit sliders 13 that are close to each other. The distance between the four clamping ring blocks 9 is adjusted according to the inner diameter of the gear to clamp it. A threaded rod 10 is rotatably connected to the inner wall of the groove, and the outer wall of the threaded rod 10 is threadedly connected to the inner wall of the clamping ring blocks 9. The rotation of the threaded rod 10 causes the clamping ring blocks 9 to rotate. Block 9 slides; four threaded rods 10 are fixedly connected to a second bevel gear 14 at one end; an adjusting rod 11 is rotatably connected to the inner wall of the support rod 3; a first bevel gear 15 is fixedly connected to the front end of the adjusting rod 11; the outer wall of the second bevel gear 14 meshes with the outer walls of the four second bevel gears 14; the adjusting rod 11 drives the first bevel gear 15 to rotate and meshes with the second bevel gear 14 to drive the second bevel gear 14 to rotate; the rotation of the second bevel gear 14 drives the threaded rod 10 to rotate, so as to adjust the spacing of the four clamping ring blocks 9; a servo motor 8 is fixedly connected to the rear end of the support plate 2; the rear end of the adjusting rod 11 is fixedly connected to the drive end of the servo motor 8; the servo motor 8 drives the adjusting rod 11 to rotate; a support block 6 is fixedly connected to the front side of the fireproof plate 5; the top of the support block 6 abuts against the outer wall of the flame gun 7, so that the flame gun 7 can be stored.

[0025] Reference Figure 1 , Figure 4 and Figure 5 The bottom of the operating table 1 has two connecting slots, and two connecting sliders 18 are slidably connected to the inner walls of each slot. A collection box 4 is fixedly connected to the bottom of the four connecting sliders 18 to collect gears damaged during the correction process. A limit stop 17 is fixedly connected to the bottom side of the operating table 1. The front side of the connecting slider 18 abuts against the rear side of the limit stop 17, limiting the connecting slider 18. The outer wall of the connecting slider 18 is slidably connected to the inner wall of the limit stop 17. The connecting slider 18 can slide through the inner wall of the limit stop 17 by sliding the limit stop 17 upward. An adjusting rack 12 is fixedly connected to the left side of the limit stop 17. An adjusting gear 19 is meshed with the left side of the adjusting rack 12.

An adjusting knob 16 is rotatably connected to the front side of the operating table 1. The front end of the adjusting gear 19 is fixedly connected to the rear end of the adjusting knob 16. Rotating the adjusting knob 16 causes the adjusting gear 19 to rotate.

[0026] Working principle: At the start of operation, the gear is fitted onto the four clamping ring blocks 9. The servo motor 8 is started to drive the adjusting rod 11 to rotate. The adjusting rod 11 drives the first bevel gear 15 to rotate, meshing with the second bevel gear 14, which in turn drives the second bevel gear 14 to rotate. The rotation of the second bevel gear 14 drives the threaded rod 10 to rotate, causing the clamping ring blocks 9 to slide. The spacing of the four clamping ring blocks 9 is adjusted according to the inner diameter of the gear to clamp it. After the gear is fixed, the flame gun 7 is started to heat the gear before straightening.

[0027] If a gear is damaged during the correction process, the damaged gear falls into the collection box 4 for collection. When the collection box 4 is almost full, turn the adjustment knob 16 to rotate the adjustment gear 19. The rotation of the adjustment gear 19 meshes with the adjustment rack 12, causing the adjustment rack 12 to slide and the limit stop 17 to slide upward, releasing the fixation of the connecting slider 18 and removing the second bevel gear 14 from the operating table 1 for tilting.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
