Description

Technical Field

[0001] The utility model relates to the technical field of tripod rack processing, in particular to a heat treatment furnace for tripod rack processing. Background Art

[0002] The tripod universal joint assembly consists of a tripod, a ball table, a needle roller, a retaining ring and a retaining spring. It is mainly assembled on the automobile constant velocity universal joint drive shaft assembly and then installed on the vehicle for use. During the production process of the tripod, the tripod often needs to be carburized and heat treated.

[0003] For example, the three-pin frame carburizing hot place with waste gas treatment disclosed in publication number CN214088635U is a device which fixes the three-pin frame to a first fixed block and a clamping block, and then moves it into a heating box through an electric telescopic rod to perform heating.

[0004] However, the heating structure can only fix the tripod rack when in use. When the tripod rack is located inside the heating box for heating, since the tripod rack has three sets of support rods and the hot air inside the heating box is not evenly distributed, the tripod rack cannot be rotated during heating to improve the heating effect, thereby reducing the use effect of the device. In view of this, we propose a heat treatment furnace for tripod rack processing. Utility Model Content

[0024] Specifically, the adjustment mechanism 3 of the technical solution of the utility model includes: a control box 31, an electric push rod 32, a fixing frame 33, a slide slot 34, a connecting plate 35, a rotating rod 36, a rotating gear 37, a clamp 38, a tooth plate 39, and a tripod body 310.

[0025] In one embodiment of the utility model, an adjustment mechanism 3 is provided to facilitate uniform heating of multiple sets of tripod bodies 310 inside the furnace body 1. When processing the tripod body 310, the user can first detachably connect the tripod body 310 with the clamp 38, and the clamp 38 can be any existing clamping device. Then the user can start the electric push rod 32 to work, and the output shaft of the electric push rod 32 moves the fixed frame 33 on its side wall. The fixed frame 33 moves and drives the three sets of tripod bodies 310 into the heating chamber 2 of the furnace body 1. Then the user can start the two sets of heating elements 6 to heat the inside of the furnace body 1.

[0026] Then the user can start the motor 7 to work, and the output shaft of the motor 7 rotates to drive the rotating rod 46 at its lower end to rotate, and the rotating rod 46 rotates to drive the semi-gear 47 on its surface to rotate, and the meshing between the semi-gear 47 and the rack 45 makes the rack 45 drive the extrusion rod 42 to move to the left, and the rotating rod 46 drives the semi-gear 47 to continue to rotate. At this time, the semi-gear 47 is no longer meshed with the rack 45, and the extrusion rod 42 is driven to move to the right for reset by the elastic force of the reset spring 43, and finally the extrusion rod 42 is continuously rotated by the semi-gear 47 to make the extrusion rod 42 move back and forth left and right, and the movement of the extrusion rod 42 drives the connecting plate 35 of its side wall to move.

[0027] At this time, the movement of the connecting plate 35 will drive the rotating rod 36 inside it to move. When the rotating rod 36 moves, the engagement of the rotating gear 37 and the tooth plate 39 on its side wall will drive the clamp 38 and the tripod body 310 to rotate back and forth, so that the tripod body 310 can be heated more evenly inside the furnace body 1.

[0028] Please continue reading Figure 1-Figure 5 The moving mechanism 4 includes a fixed frame 41 fixedly mounted on the side wall of the fixed frame 33, an extrusion rod 42 is penetrated inside the fixed frame 41, a return spring 43 is arranged on the surface of the extrusion rod 42, a partition 44 is fixedly mounted on the inner wall of the fixed frame 41, a rack 45 is fixedly mounted on the side wall of the extrusion rod 42, a rotating rod 46 is rotatably connected to the inner wall of the fixed frame 41, a half gear 47 is fixedly mounted on the surface of the rotating rod 46, the end of the extrusion rod 42 is fixedly connected to the side wall of the connecting plate 35, a motor 7 is fixedly mounted on the upper end of the fixed frame 33, the output shaft of the motor 7 penetrates the inner wall of the fixed frame 41 and is fixedly connected to the upper end of the rotating rod 46, one end of the return spring 43 is fixedly connected to the side wall of the fixed frame 41, and the other end of the return spring 43 is fixedly connected to the side wall of the partition 44, the rotating gear 37 and the toothed plate 39 are in a meshing state, and heat insulation plates 8 are fixedly mounted on both sides of the inner wall of the heating chamber 2, and multiple groups of connecting plates 35 are fixedly connected by two groups of fixed columns 9.

[0029] During operation, the user can first detachably connect the tripod body 310 with the clamp 38, and then start the electric push rod 32 to drive the fixing frame 33 to move, and drive the three sets of tripod bodies 310 to enter the heating chamber 2 of the furnace body 1 through the movement of the fixing frame 33, and then start the two sets of heating elements 6 to heat the inside of the furnace body 1, and then start the motor 7 to work, the output shaft of the motor 7 rotates to drive the rotating rod 46 to rotate, the rotating rod 46 rotates to drive the half gear 47 to rotate, the meshing between the half gear 47 and the rack 45 causes the rack 45 to drive the extrusion rod 42 to move to the left, and at this time the rotating rod 46 drives the half gear 47 continues to rotate. At this time, the half gear 47 is no longer engaged with the rack 45. The elastic force of the reset spring 43 drives the extrusion rod 42 to move to the right for reset. Finally, the half gear 47 is continuously rotated to make the extrusion rod 42 move back and forth. The movement of the extrusion rod 42 drives the connecting plate 35 of its side wall to move. At this time, the movement of the connecting plate 35 drives the rotating rod 36 to move. When the rotating rod 36 moves, the engagement of the rotating gear 37 and the toothed plate 39 drives the clamp 38 and the tripod body 310 to rotate back and forth, so that the tripod body 310 is more evenly heated inside the furnace body 1.
