Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a device for chamfering gears. Background Technology

[0002] The existing gear chamfering method is as follows: A machine tool drives the gear to rotate, a first motor drives the chamfering cutter to rotate, and a second motor drives the first motor and the chamfering cutter to swing together. Each time the gear rotates by a certain angle, the second motor drives the chamfering cutter to swing into the end of a tooth groove. The chamfering cutter, driven by the first motor, chamfers the edge of that tooth groove end. After chamfering, the second motor drives the chamfering cutter to swing back and exit from the end of the tooth groove. This cycle is repeated to chamfer one end of the gear. After chamfering one end of the gear, the gear is removed, flipped, and then mounted back onto the machine tool to chamfer the other end of the gear.

[0003] The existing gear chamfering method involves the tool oscillating intermittently to enter the chamfering end of the tooth groove, and requires two clamping operations to complete the chamfering of the edges at both ends of the gear, resulting in low chamfering efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a double-sided chamfering device for gear rings to solve the technical problems of existing gear chamfering methods, which require the cutting tool to intermittently swing to enter the end of the tooth groove for chamfering, and the gear to be clamped twice to complete the chamfering of both ends of the edge, resulting in low gear chamfering efficiency.

[0005] This utility model of a double-sided chamfering device for a gear ring includes a support body, a first straight guide rail group horizontally fixed on the support body, a first slide block disposed on the first straight guide rail group, a first linear driver that drives the first slide block to move along the first straight guide rail, a first motor horizontally fixed on the first slide block, and a 90° angler disposed on the first slide block. The input shaft of the 90° angler is connected to the rotor shaft of the first motor, and the output shaft of the 90° angler is connected to the chamfering cutter.

[0006] Furthermore, the first linear actuator is an electric ball screw.

[0007] Furthermore, the support body is also provided with a second straight guide rail group, a second slide block provided on the second straight guide rail group, a second linear driver that drives the second slide block to move along the second straight guide rail, a second motor that is horizontally fixed on the second slide block, and a grinding wheel connected to the rotor shaft of the second motor.

[0008] Furthermore, the second linear actuator is a cylinder.

[0009] Furthermore, the support body includes a base, a guide column vertically fixed on the base, a lifting seat that slides up and down with the guide column, and a lifting driver for adjusting the up and down position of the lifting seat.

[0010] Furthermore, the lifting seat is provided with a guide sleeve that slides up and down with the guide column, and the guide sleeve is provided with a locking screw.

[0011] Furthermore, the lifting drive is an electric ball screw.

[0012] The beneficial effects of this utility model are:

[0013] This utility model relates to a double-sided chamfering device for gear rings. After being installed on a chamfering machine, the axial direction of the chamfering cutter is perpendicular to the axial direction of the gear ring. During chamfering, the cutting edge of the chamfering cutter is located at the tooth groove opening on the end face of the gear ring. The chamfering cutter is always in a rotating chamfering state and does not swing, resulting in a fast chamfering speed. After the edge of one end face of the gear ring is chamfered, the first linear drive drives the chamfering cutter to move forward to the other end face of the gear for chamfering. The gear ring only needs to be clamped once to complete the chamfering of the edges of both end faces of the gear ring, resulting in high chamfering efficiency. Attached Figure Description

[0016] Figure 3 This is a schematic diagram of the improved support structure. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, the double-sided chamfering device for the gear ring in this embodiment includes a support body 1, a first straight guide rail group 2 horizontally fixed on the support body, a first slide block 3 disposed on the first straight guide rail group, a first linear actuator 4 driving the first slide block to move along the first straight guide rail, a first motor 5 horizontally fixed on the first slide block, and a 90° angler 6 disposed on the first slide block. The input shaft of the 90° angler is connected to the rotor shaft of the first motor 5, and the output shaft of the 90° angler is connected to the chamfering cutter 7. In this embodiment, the first linear actuator 5 is an electric ball screw, and the nut that mates with the ball screw is connected to the first slide block. The stepper motor or servo motor that drives the ball screw to rotate is disposed on a first support 8 fixed to the support body 1. Of course, in different embodiments, the first linear actuator 5 can also be other forms such as a digital hydraulic cylinder.

[0019] like Figure 1-3 As shown, the support body of the double-sided chamfering device for the gear ring in this embodiment is installed and fixed on a chamfering machine tool, with the axial direction of the chamfering cutter perpendicular to the axial direction of the gear ring. During chamfering, the first linear actuator 5 drives the first slide 3 to move forward, so that the cutting edge of the chamfering cutter is located at the tooth groove opening on the end face of the gear ring. The first motor drives the chamfering cutter to always be in a rotating chamfering state, and the chamfering cutter does not swing. Taking a chamfering cutter with two chamfering cutting edges as an example, the chamfering cutter completes the chamfering of one tooth groove edge every half turn. The gear ring is driven to rotate by the machine tool spindle. After one cutting edge has chamfered the end edge of one tooth groove, the other cutting edge will screw into the adjacent tooth groove to chamfer it. This cycle of chamfering is repeated, and the chamfering speed is fast. After the edge of one end face of the gear ring is chamfered, the electric ball screw drives the chamfering cutter to move forward to the other end face of the gear to chamfer it. The gear ring only needs to be clamped once to complete the chamfering of the edges of both end faces of the gear ring, resulting in high chamfering efficiency.

[0020] As an improvement to the above embodiment, the support body is further provided with a second linear guide rail group 9, a second slide block 10 disposed on the second linear guide rail group, a second linear actuator 11 that drives the second slide block to move along the second linear guide rail, a second motor 12 horizontally fixed on the second slide block, and a grinding wheel 13 connected to the rotor shaft of the second motor. In this embodiment, the second linear actuator is a cylinder; however, in different embodiments, the second linear actuator can also be an electric ball screw. After the gear ring edge is chamfered, some burrs may remain on the edge. In this improvement, after chamfering, the worktable of the machine tool spindle is moved forward first, so that the tooth end face of the gear ring 14 is aligned with the grinding wheel 13. Then, the grinding wheel 13 is driven forward by the second linear actuator 11 to grind the tooth end face of the gear ring, thereby removing the end face burrs.

[0021] As an improvement to the above embodiments, such as Figure 3 As shown, the support body 1 includes a base 101, a guide column 102 vertically fixed on the base, a lifting seat 103 that slides vertically with the guide column, and a lifting driver 104 for adjusting the vertical position of the lifting seat. In this embodiment, the lifting driver is an electric ball screw, the nut of the electric ball screw is connected to the lifting seat 103, and the servo motor or stepper motor driving the screw is fixed on the base 101. After installing the double-sided chamfering device of the gear ring in this embodiment on the machine tool, before the formal chamfering work, it is necessary to adjust the height position of the chamfering cutter so that the cutting edge can just enter a tooth groove to complete the chamfering. This improvement adjusts the height position of the chamfering cutter 7 by driving the lifting seat 103 to rise and fall with the electric ball screw, which is convenient and can improve the efficiency of debugging.

[0022] As an improvement to the above embodiment, the lifting seat is provided with a guide sleeve 105 that slides vertically with the guide column, and the guide sleeve is provided with a locking screw 106. The sliding engagement between the guide sleeve 105 and the guide column 102 allows for a sliding fit gap. After the chamfering tool height is adjusted to the correct position, the guide sleeve 105 is locked and fixed to the guide column 102 by the locking screw 106, which improves the overall stability of the system.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
