Description

Technical Field

[0001] The utility model relates to the technical field of fixture equipment for gear shaping machines, in particular to a fixture fixing structure for gear shaping machines. Background Art

[0002] Gear shaping machines are required for gear processing. Gear shaping machines must be equipped with fixed tooling for effective clamping and fixing in order to process gears of different specifications.

[0003] The Chinese utility model patent number CN214053960U currently discloses a new type of processing tooling for a gear planing machine. Through the mutual cooperation of a base, a pressure plate, a support block, a positioning groove, a positioning block, a rolling bearing, a fixed shaft, a baffle, a rubber block, a fixed rod, a slider, a movable plate, a clamping block, a clamping groove and a buffer spring, different pressure plates can be replaced according to gears of different specifications. The replacement process is simple and convenient, which greatly improves the replacement efficiency and avoids the need for different tooling for gears of different specifications, bringing great convenience to users.

[0004] However, the above-mentioned prior art clamps the outer diameter of the gear during use. Since the gear planing machine processes teeth on the outer wall of the gear during processing, clamping the outer diameter of the gear makes the gear particularly inconvenient during processing and is likely to cause damage to the gear, thereby reducing the practicality of gear processing. In view of this, we design a tooling fixing structure for gear planing machine processing. Utility Model Content

[0005] In response to the above technical problems, the utility model provides a tool fixing structure for gear planing machine processing. The designed fixing structure squeezes and clamps the inner diameter of the gear when fixing the gear, thereby completing the clamping and fixing of the gear without affecting the tooth processing of the outer diameter of the gear, and is highly practical.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A tool fixing structure for gear planing machine processing, characterized in that it includes a support seat, a support rod, a mounting frame, a motor, a transmission assembly, a bidirectional screw and a clamping plate, one end of the support rod is fixedly connected to the support seat, the other end of the support rod is fixed to the mounting frame, the motor is installed on the mounting frame, the motor is connected to the bidirectional screw rod through the transmission assembly, the two ends of the bidirectional screw rod are respectively mounted on the mounting frame through bearings, the two sides of the bidirectional screw rod are respectively threadedly connected to the moving block, the moving block is provided with a connecting assembly and is connected to the clamping plate through the connecting assembly,

[0008] The transmission assembly consists of a driving wheel and a driven wheel. The driving wheel is connected to the output end of the motor, the driving wheel is meshed with the driven wheel, and the driven wheel is connected to the bidirectional screw rod.

[0009] The connecting assembly consists of a connecting rod, a mounting plate and a fixing nail. One end of the connecting rod is fixedly connected to the moving block, and the other end of the connecting rod is fixed to the mounting plate. The mounting plate is connected to the clamping plate through the fixing nail.

[0010] Specifically, the outer side of the clamping plate is provided with anti-skid rubber, and the anti-skid rubber creates friction between the clamping plate and the inner diameter of the gear, thereby preventing the gear from sliding on the clamping plate.

[0011] Specifically, the threads at both ends of the bidirectional screw rod are in opposite directions.

[0012] Specifically, the bidirectional screw rod is located in a movable groove provided on the mounting frame.

[0013] Specifically, the connecting rod passes through and extends from a limiting groove provided on the mounting frame.

[0014] Beneficial effects of the utility model:

[0015] The fixing structure designed by the utility model is that when fixing the gear, the mounting frame and the clamping plate are both extended into the inner diameter of the gear, and then the motor is started to control the rotation of the bidirectional screw rod, so that the moving blocks threadedly connected to the bidirectional screw rod move in opposite directions, and the clamping plates on both sides move toward the inner wall of the gear, and then spread out to abut against the gear, squeezing the inner diameter of the gear, thereby limiting and fixing the gear on the clamping plate, thus completing the clamping and fixing of the gear, without affecting the tooth processing of the outer diameter of the gear, and having strong practicality;

[0016] The splint designed in the utility model is fixed to the mounting plate by fixing nails. The splint is installed in a detachable manner, so that the splint of corresponding size can be replaced according to gears of different specifications, avoiding the need for matching fixing tooling for gears of different specifications, thereby greatly reducing production costs.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] As shown in the figure, one end of the support rod 2 is fixedly connected to the support base 1, and the other end of the support rod 2 is fixed to the mounting frame 3. The motor 4 is installed on the mounting frame 3. The output end of the motor 4 is connected to the driving wheel 51, and the driving wheel 51 is meshed with the driven wheel 52. The driven wheel 52 is connected to the bidirectional screw rod 6. The two ends of the bidirectional screw rod 6 are respectively installed on the mounting frame 3 through bearings, and are located in the movable groove provided on the mounting frame 3.

[0025] The threads at both ends of the bidirectional screw rod 6 are in opposite directions. The two sides of the bidirectional screw rod 6 are respectively threadedly connected to the moving block 8. The two ends of the moving block 8 are respectively fixed with a connecting rod 91. The other end of the connecting rod 91 passes through the limit groove provided on the mounting frame 3 and extends to be fixed with the mounting plate 92. The mounting plate 92 is connected to the splint 7 through a fixing nail 93

[0026] The outer side of the clamping plate 7 is provided with an anti-skid rubber 71, and the anti-skid rubber 71 creates friction between the clamping plate 7 and the inner diameter of the gear, preventing the gear from sliding on the clamping plate.

[0027] Example 2

[0028] When fixing the gear, the mounting frame 3 and the clamping plate 7 are both extended into the inner diameter of the gear, and then the motor 4 is started to drive the driving wheel 51 to rotate. The meshing transmission of the driving wheel 51 and the driven wheel 52 causes the driven wheel 52 to rotate, thereby driving the bidirectional screw rod 6 to rotate, so that the moving blocks 8 threadedly connected to the two ends of the bidirectional screw rod 6 move in opposite directions, thereby controlling the clamping plates 7 on both sides to move toward the inner wall of the gear. The two clamping plates 7 respectively abut on the inner diameter of the gear and squeeze the inner diameter of the gear, thereby fixing the gear on the clamping plate 7, that is, completing the clamping and fixing of the gear without affecting the processing operation of the outer diameter of the gear, and having strong practicality.

[0029] When the gear processing is completed and the processed tooling needs to be removed, the motor 4 is controlled to reverse, thereby controlling the moving blocks 8 at both ends of the bidirectional screw 6 to move toward each other, so that the clamping plates 7 on both sides move toward the mounting frame 3, thereby releasing the extrusion limit on the inner diameter of the gear, and the processed gear can be removed;

[0030] Among them, the splint 7 is fixed to the mounting plate 92 by using fixing nails 93. The splint 7 is installed in a detachable manner, so that the splint 7 of corresponding size can be replaced according to gears of different specifications, avoiding the need for matching fixing tooling for gears of different specifications, thereby greatly reducing production costs.
