Description

Technical Field

[0001] The utility model belongs to the technical field of gear shaft quenching, and particularly relates to a tooling for conveniently fixing gear shaft quenching. Background Art

[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. Generally, it is a metal round rod, and each section can have different diameters. During the quenching process of the gear shaft, a tooling for gear shaft quenching will be used.

[0003] However, when the existing tooling for gear shaft quenching quenches the gear shaft, there is a lack of correction and fixation in the vertical direction of the gear shaft, which will lead to a reduction in the precision of the finished product after quenching of the gear shaft, as well as excessive quenching deformation or cracking caused by uneven quenching of the gear shaft during the quenching process. Therefore, there is an urgent need for a tooling for conveniently fixing gear shaft quenching to solve the above problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is the lack of correction and fixation in the vertical direction during the quenching process, as well as excessive quenching deformation or cracking caused by uneven quenching of the gear shaft during the quenching process.

[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: A tooling for conveniently fixing gear shaft quenching, including a support main frame, and a quenching barrel fixedly arranged on the support main frame. Opposite opening grooves are arranged on the side wall of the support main frame, a vertical correction component is arranged on the opening grooves, and a rotary clamping component penetrating through the support main frame is arranged at the upper end of the support main frame.

[0006] In order to smoothly achieve the purpose of vertical correction and fixation, the vertical correction component includes: a first cylinder fixedly connected to the side wall of the support main frame, a push rod connected to the output end of the first cylinder, and a toothed chain combined rod fixedly connected to one end of the push rod and slidably arranged on the side wall of the support main frame.

[0007] It also includes a right correction rod and a left correction rod rotatably connected to the opening groove relatively. A first gear is fixedly arranged on the right correction rod, a second gear is fixedly arranged on the left correction rod. An arc-shaped clamp penetrating through the right correction rod is arranged on the right correction rod. Springs with both ends connected to the right correction rod and the arc-shaped clamp are annularly arranged on the outer wall of the arc-shaped clamp. A notch is opened at the position where the right correction rod is close to the left correction rod. The arc-shaped clamp is slidably arranged in the notch of the right correction rod through the spring. The left correction rod and the right correction rod are arranged with the same structure.

[0008] In order to smoothly achieve the purpose of uniform quenching, the rotary clamping assembly includes a second cylinder fixedly arranged at the upper end of the support main frame. A motor cooperating with the second cylinder is fixedly arranged on one side of the second cylinder. The lower output end of the second cylinder is connected with a lifting rod penetrating through the top end of the support main frame. The lower end of the lifting rod is fixedly connected with a housing. A left clamping rod is fixedly arranged on the inner wall of the housing. A right clamping rod is slidably connected to the inner wall of the upper end of the housing. It also includes a bolt penetrating through the side wall of the housing and rotatably connected to the right clamping rod.

[0009] Further, tooth chains are symmetrically arranged on the tooth chain combination rod. The maximum angle between the right correction rod and the left correction rod is 120 degrees. A rotating shaft penetrating through the right correction rod is arranged at the center of the first gear. The rotating shaft is rotatably connected to the opening groove. The left correction rod has the same structure as the right correction rod and is also rotatably connected to the opening groove.

[0010] Further, the vertical correction assembly and the rotary clamping assembly are arranged perpendicular to each other.

Springs are connected between the arc-shaped clamps and the correction rods. When the gear shaft is clamped, the left and right springs give the arc-shaped clamps a force in the horizontal direction, so as to achieve the vertical clamping and correction of the gear shaft.

A rotary clamping assembly 4 is provided at the upper end of the support main frame 1 and penetrates through the support main frame 1. The vertical calibration assembly 3 and the rotary clamping assembly 4 are arranged perpendicular to each other.

[0024] As Figures 2-3 shown, the vertical calibration assembly 3 includes: a first cylinder 31 fixedly connected to the side wall of the support main frame 1. The output end of the first cylinder 31 is connected to a push rod 32. One end of the push rod 32 is fixedly connected to a tooth chain combined rod 33 slidably arranged on the side wall of the support main frame 1;

[0025] It further includes a right calibration rod 34 and a left calibration rod 35 which are relatively rotatably connected to the opening groove 2. A first gear 36 is fixedly arranged on the right calibration rod 34, and a second gear 37 is fixedly arranged on the left calibration rod 35. The right calibration rod 34 is provided with an arc-shaped clamp 38 penetrating through it. A spring 39 with both ends connected to the right calibration rod 34 and the arc-shaped clamp 38 is annularly arranged on the outer wall of the arc-shaped clamp 38. A notch is formed at the position where the right calibration rod 34 is close to the left calibration rod 35. The arc-shaped clamp 38 is slidably arranged at the notch of the right calibration rod 34 through the spring 39. The left calibration rod 35 and the right calibration rod 34 are arranged with the same structure. Tooth chains are symmetrically arranged on the tooth chain combination rod 33. The tooth chains are meshed with the first gear 36, and the first gear 36 is meshed with the second gear 37. The maximum angle between the right calibration rod 34 and the left calibration rod 35 is 120 degrees.

[0026] Reference Figure 3 As shown, a rotating shaft penetrating through the right calibration rod 34 is arranged at the center of the first gear 36. It is rotationally connected to the opening groove 2 through the rotating shaft. The left calibration rod 35 refers to the structure of the right calibration rod 34 and is also rotationally connected to the opening groove 2.

[0027] As Figure 2 and Figure 4 shown, the rotary clamping assembly 4 includes a second cylinder 41 fixedly arranged at the upper end of the support main frame 1. A motor 42 cooperating with the second cylinder 41 is fixedly arranged on one side of the second cylinder 41. A lifting rod 43 penetrating through the top end of the support main frame 1 is connected to the lower output end of the second cylinder 41. A housing 44 is fixedly connected to the lower end of the lifting rod 43. A left clamping rod 45 is fixedly arranged on the inner wall of the housing 44. A right clamping rod 46 is slidably connected to the upper inner wall of the housing 44.

Then, the motor 42 and the second cylinder 41 are started. The motor 42 drives the output end of the cylinder to rotate through the transmission belt, and the housing 44 connected to the output end of the cylinder moves in the vertical direction, so that the gear shaft fixed between the left clamping rod 45 and the right clamping rod 46 extends into the quenching barrel 5 and rotates at a uniform speed, achieving the purpose of uniform quenching.
