A helical gear orienting hole machining device

Abstract

This utility model discloses a helical gear orienting hole processing device, including a support base and an electric drive wheel, which are disposed opposite each other on the top of the support base; and a mounting base, which is fixedly installed on the side of the support base. In this solution, when the angle position of the helical gear needs to be adjusted, the electric push rods disposed on both sides of the top of the support base retract. At this time, the clamping ring at one end of the electric push rod moves horizontally and disengages from the surface of the helical gear. Simultaneously, the contact wheel moves in the opposite direction under the drive of the elastic element and contacts the surface of the helical gear. Then, the electric drive wheel on the top of the support base rotates, and the clamping ring returns to its original position to tighten the helical gear for continued processing. This simplifies the helical gear adjustment process, reduces time consumption, ensures normal processing, and improves the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of internal keyway machining technology, and more specifically, to a helical gear directional hole machining device. Background Technology

[0002] The existing equipment processes the keyway by planing. The surface roughness accuracy of the planed surface is low and the dimensional tolerance is large, which has a significant impact on the assembly of the keyway and key. The assembly clearance will also affect the service life of the helical gear.

[0003] To address the aforementioned issues, patent document publication number CN219925184U discloses a processing device for keyways of helical gears, comprising a support base and a power box. The power box is fitted onto the side of the support base, and a rotating seat is mounted at the upper center of the power box. A rotating mounting plate is mounted above the rotating seat, and a double-rod hydraulic cylinder is fixedly mounted above the rotating mounting plate. A first telescopic rod is provided on one side of the double-rod hydraulic cylinder.

[0004] However, it still has some drawbacks in actual use. For example, after the helical gear is fixed, if the angle or position of the keyway needs to be adjusted, the locking nut must be loosened, the pressure plate lifted, the helical gear manually rotated, and then the gear re-tightened and fixed. The adjustment process is cumbersome and reduces the practicality of the device to some extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a helical gear orientation hole processing device to solve the problem that the helical gear is inconvenient to adjust after it is fixed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a helical gear orientation hole processing device, including a support base, the helical gear orientation hole processing device further includes...

[0007] Electric drive wheels, which are arranged opposite each other on both sides of the top of the support base;

[0008] Mounting base, the mounting base is fixedly installed on the side of the support base;

[0009] An electric push rod is provided on the surface of the mounting base, and a clamping ring is fixedly installed at the extended end of the electric push rod. The bottom surface of the clamping ring is in contact with the top surface of the support base.

[0010] A first bonding wheel is disposed on the surface of the clamping ring.

[0011] It also includes auxiliary components, which are disposed opposite each other on both sides of the support surface.

[0012] The auxiliary components include a motor, a screw, a connecting end, a connecting frame, and a bonding plate. The motor is disposed opposite to each other on the surface of the support base. The drive shaft of the motor is fixedly connected to one end of the screw, and the other end of the screw is fixedly connected to the surface of the connecting end. The connecting end is rotatably connected to the inner wall of the support base on one side relative to the screw. The connecting frame is threaded onto the surface of the screw, and the surface of the connecting frame is in contact with the surface of the support base. The bonding plate is disposed on the top of the connecting frame, and one side of the bonding plate is in contact with the bottom of the helical gear.

[0013] The assembly includes a rotating column, a torsion spring, a fixed end, an arc-shaped plate, a connecting ring, a mounting shaft, and a second bonding wheel. The rotating column is rotatably mounted on the surface of the bonding plate. One end of the torsion spring is fixedly connected to the inner wall of the rotating column end, and the other end of the torsion spring is fixedly connected to the inside of the fixed end. The fixed end is fixedly mounted on the surface of the bonding plate. The inner wall of the rotating column end is rotatably connected to the surface of the fixed end. The arc-shaped plate is fixedly mounted on the surface of the rotating column. The connecting ring is located on the side of the arc-shaped plate opposite to the rotating column. The mounting shaft is rotatably mounted on the inner ring of the connecting ring. The second bonding wheel is fixedly mounted on the surface of the mounting shaft.

[0014] It also includes a helical gear, which is placed on top of the support base, and the outer periphery of the helical gear is in contact with the surface of the clamping ring.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, when the angle of the helical gear needs to be adjusted, the electric push rods set on both sides of the top of the support base are retracted. At this time, the clamping ring set at one end of the electric push rod moves horizontally and disengages from the surface of the helical gear. At the same time, the first contact wheel moves in the opposite direction under the drive of the elastic element and contacts the surface of the helical gear. Then, the electric drive wheel set on the top of the support base rotates. The friction between the electric drive wheel and the surface of the helical gear drives the helical gear to rotate, thereby adjusting the angle of the helical gear. Afterward, the clamping ring is reset and moved to tighten the helical gear so that processing can continue. This simplifies the process of adjusting the helical gear, does not require much time, ensures that the processing work can proceed normally, and improves the practicality of the device.

[0017] The motor drives the screw to rotate, allowing the connecting bracket mounted on the screw surface to move horizontally. This causes the bonding plate to move synchronously, bringing it into contact with the bottom of the helical gear. This provides longitudinal support for the helical gear. Furthermore, when the helical gear is rotated for adjustment, the bonding plate separates from the bottom of the helical gear. Simultaneously, under the elastic action of the torsion spring, the arc-shaped plate, along with the rotating column, deflects, causing the second bonding wheel to contact the bottom of the helical gear. This longitudinal limitation is achieved without affecting the normal rotation of the helical gear, further improving the device's practicality. Attached Figure Description

[0029] The first contact wheel 6 is set on the surface of the clamping ring 5. The first contact wheel 6 is connected to the clamping ring 5 by an elastic element. Without affecting the normal rotation of the first contact wheel 6, when the clamping ring 5 is in close contact with the surface of the helical gear 8, the first contact wheel 6 can move in the opposite direction of the movement of the clamping ring 5, so as to avoid the fixed position of the first contact wheel 6 affecting the tightness of the clamping ring 5 and the helical gear 8.

[0030] It also includes auxiliary components 7, which are disposed on opposite sides of the surface of the support base 1.

[0031] The auxiliary component 7 includes a motor 71, a screw 72, a connecting end 73, a connecting frame 74, and a bonding plate 75.

The connecting frame 74 is threaded onto the surface of the screw 72, and the surface of the connecting frame 74 is in contact with the surface of the support base 1. The bonding plate 75 is disposed on the top of the connecting frame 74, and one side of the bonding plate 75 is in contact with the bottom of the helical gear 8. Through the bonding plate 75, it can move horizontally under the drive of the motor 71, thereby cooperating with the clamping ring 5 to further limit the helical gear 8 and ensure that it can maintain a fixed position during processing.

[0032] The assembly includes a rotating column 76, a torsion spring 77, a fixed end 78, an arc-shaped plate 79, a connecting ring 710, a mounting shaft 711, and a second bonding wheel 712.

[0035] The working process of this utility model is as follows: When it is necessary to adjust the angle position of the helical gear 8, the electric push rods 4 set on both sides of the top of the support base 1 are retracted. At this time, the clamping ring 5 set at one end of the electric push rod 4 moves horizontally and disengages from the surface of the helical gear 8. At the same time, the contact wheel 6 moves in the opposite direction under the drive of the elastic element and contacts the surface of the helical gear 8. Then, the electric drive wheel 2 set on the top of the support base 1 rotates. The friction between the electric drive wheel 2 and the surface of the helical gear 8 drives the helical gear 8 to rotate, so as to adjust the angle of the helical gear 8. Afterwards, the clamping ring 5 is reset and moved to tighten the helical gear 8 so as to continue processing.
