Technical Field
[0001] This utility model relates to the field of bevel gear processing technology, specifically a calibration device for bevel gear milling fixtures. Background Technology
[0002] The earliest bevel gears were primitive planar wooden gears, mainly used in simple mechanical devices to transmit motion and power between intersecting shafts. With the development of metallurgical technology, bevel gears began to be made of copper and cast iron, which improved their durability and expanded their application range. Steel began to be widely used in the manufacture of bevel gears, which greatly improved their strength and load-bearing capacity. At the same time, the continuous progress of machining technology, especially the application of the generating principle in gear machining, has significantly improved the machining accuracy and production efficiency of bevel gears.
[0003] In the existing technology, milling is a key process in the mass production of bevel gears. Milling tooling calibration devices can be used to accurately calibrate the tooling after it is installed on the milling machine. However, during use, it is not possible to quickly position the bevel gears according to different models and sizes, and the calibration devices usually cannot perform multi-directional precise adjustments.
[0004] Therefore, a calibration device for bevel gear milling fixtures is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a calibration device for bevel gear milling fixtures to solve the problems mentioned in the background art.

A double-ended motor is fixedly installed on the inner wall surface of the perforated sleeve rod, and a second rotating shaft is fixedly installed at the output end of the double-ended motor. The other end of the second rotating shaft movably penetrates the inner wall surface of the perforated sleeve rod and extends to the outside of the perforated sleeve rod. A gear is fixedly installed at the other end of the second rotating shaft, and a semi-circular toothed plate is meshed with the surface of the gear. The surface of the semi-circular toothed plate is fixedly installed on the sleeve block. On the inside, the T-shaped support plate can be moved horizontally by the cooperation between the connecting seat, lead screw one, horizontal motor, threaded sleeve block, and limit block.

The positioning and clamping assembly can be adjusted in tilt angle by the cooperation between the rotating rod, hollow sleeve rod, double-end motor, gear, and semi-circular toothed plate. The multi-axis fine adjustment structure allows the tooling to be adjusted simultaneously in the horizontal, vertical, and tilt directions, avoiding the cumulative error that may occur when adjusting in each direction, and ultimately achieving the effect of multi-axis adjustment.
[0011] Preferably, the positioning and clamping assembly specifically includes: a positioning cylinder, which is fixedly installed on the top of the hollow sleeve rod; and a base, which is fixedly sleeved on the outer wall of the positioning cylinder.

[0014] This utility model provides a calibration device for a bevel gear milling fixture. It has the following beneficial effects:
[0015] (1) This utility model improves accuracy by setting up a multi-axis adjustment component to adjust in multiple directions. The horizontal motor is started to drive the lead screw one to rotate, and drives the threaded sleeve block and T-shaped support plate to adjust in the horizontal direction. The vertical motor is started to drive the lead screw two to rotate. Under the action of the threaded inner seat, the lead screw two, the vertical motor and the sleeve block will move in the vertical direction.

[0016] (2) This utility model can position bevel gears of different sizes by setting a positioning clamping component, thereby improving accuracy. The bevel gear is fitted onto the outer wall of the positioning cylinder, and the chassis supports the bottom. The hydraulic rod is activated to drive the conical push plate to rise. The protrusion will move outward under the action of the conical push plate and drive the spring to compress, which in turn drives the positioning rod and positioning block to position the inner wall of the bevel gear. The quick clamping structure allows the operator to install the tooling in place more quickly and start calibration and processing. The uniform clamping force helps to reduce the local stress concentration of the tooling during the clamping process, improve work efficiency, and thus achieve the positioning effect.

Example
[0024] A preferred embodiment of the calibration device for a bevel gear milling fixture provided by this utility model is, for example... Figure 1-4 As shown: A calibration device for a bevel gear milling fixture includes a fixed plate 1, with connecting threaded blocks 2 fixedly installed at equal intervals on both sides of the fixed plate 1, a moving groove 3 opened on the top of the fixed plate 1, a multi-axis adjustment assembly 4 provided on the top of the fixed plate 1, and a positioning clamping assembly 5 provided on the surface of the multi-axis adjustment assembly 4.
[0025] The multi-axis adjustment assembly 4 specifically includes: a connecting seat 411, which is equidistantly fixedly installed on the top of the fixed plate 1; a lead screw 412, which is rotatably connected between the inner sides of the connecting seat 411; and a horizontal motor 413, which is fixedly installed on the outer side of the connecting seat 411.
[0026] A rotating shaft is fixedly installed at the output end of the horizontal motor 413. The other end of the rotating shaft passes through the outside of the connecting seat 411 and extends to the inside of the connecting seat 411, where it is fixedly connected to one end of the lead screw 412. A threaded sleeve 414 is threadedly connected to the outer wall of the lead screw 412. A limit block 415 is fixedly installed at the bottom of the threaded sleeve 414. The bottom of the limit block 415 extends to slide between the inner wall of the moving groove 3 and the limit block 415.
[0027] A T-shaped support plate 416 is fixedly installed on the top of the threaded sleeve block 414. A threaded inner seat 417 is fixedly installed at equal intervals on the top of the T-shaped support plate 416. A screw rod 418 is threadedly connected to the inner wall of the threaded inner seat 417. A sleeve block 419 is movably sleeved on the outer wall of the threaded inner seat 417. A vertical motor 4111 is fixedly installed on the top of the inner wall of the sleeve block 419. The output end of the vertical motor 4111 is fixedly connected to one end of the screw rod 418.
[0028] A perforated plate 4112 is fixedly installed on the top of the T-shaped support plate 416. Rotating rods 4113 are fixedly installed on both sides of the inner wall of the perforated plate 4112. The other end of the rotating rods 4113 is rotatably connected to a perforated sleeve rod 4114. The bottom of the perforated sleeve rod 4114 extends to the bottom of the perforated plate 4112. A double-end motor 4115 is fixedly installed on the inner wall surface of the perforated sleeve rod 4114. A rotating shaft II is fixedly installed at the output end of the double-end motor 4115. The other end of the rotating shaft II moves through the inner wall surface of the perforated sleeve rod 4114 and extends to the outside of the perforated sleeve rod 4114.

[0029] In this example, the multi-axis adjustment component 4 is set up to adjust in multiple directions, thereby improving accuracy. The horizontal motor 413 is started to drive the lead screw 412 to rotate, which in turn drives the threaded sleeve block 414 and the T-shaped support plate 416 to adjust in the horizontal direction. The vertical motor 4111 is started to drive the lead screw 418 to rotate. Under the action of the threaded insert seat 417, the lead screw 418, the vertical motor 4111, and the sleeve block 419 will move in the vertical direction. The double-end motor 4115 is started to drive the rotating shaft and the gear 4116 to rotate. Under the action of the semi-circular toothed plate 4117, the hollow sleeve rod 4114 will rotate inside the rotating rod 4113, thereby achieving the effect of multi-axis adjustment. Example
[0030] Based on Embodiment 1, a preferred embodiment of the calibration device for a bevel gear milling fixture provided by this utility model is, for example... Figure 1-4 As shown: The positioning and clamping assembly 5 specifically includes: a positioning cylinder 511, which is fixedly installed on the top of the hollow sleeve rod 4114; and a base plate 512, which is fixedly sleeved on the outer wall of the positioning cylinder 511.
[0031] A hydraulic rod 513 is fixedly installed on the bottom of the inner wall of the positioning cylinder 511. A conical push plate 514 is fixedly installed on the telescopic end of the hydraulic rod 513. Positioning rods 515 are evenly and equidistantly arranged on the outer circumference of the positioning cylinder 511.
[0032] A positioning block 516 is fixedly installed at one end of the positioning rod 515, and the other end of the positioning rod 515 movably passes through the outer wall of the positioning cylinder 511 and extends into the interior of the positioning cylinder 511. A protrusion 517 is fixedly installed at the other end of the positioning rod 515. A spring 518 is movably sleeved on the outer wall of the positioning rod 515. One end of the spring 518 is fixedly connected to the inner wall surface of the positioning cylinder 511, and the other end of the spring 518 is fixedly connected to the surface of the protrusion 517.
[0033] In this example, the positioning clamping component 5 can be used to position bevel gears of different sizes, improving accuracy. The bevel gear is fitted onto the outer wall of the positioning cylinder 511, and the chassis 512 supports the bottom. The hydraulic rod 513 is activated to drive the conical push plate 514 to rise. The protrusion 517 moves outward under the action of the conical push plate 514, and drives the spring 518 to be compressed, which further drives the positioning rod 515 and the positioning block 516 to position the inner wall of the bevel gear, thereby achieving the positioning function.
[0034] Working Principle: First, this equipment requires an external power supply. It can be fixed to the worktable via the connecting threaded block 2. The bevel gear is fitted onto the outer wall of the positioning cylinder 511, and the base 512 supports the bottom of the bevel gear. Then, the hydraulic rod 513 is activated, causing the conical push plate 514 to rise. The protrusion 517 moves outward under the action of the conical push plate 514, compressing the spring 518. This further drives the positioning rod 515 and positioning block 516 to position the inner wall of the bevel gear. When horizontal movement is required, the horizontal motor 413 is activated, driving the lead screw 412 to rotate, which in turn drives the threaded sleeve 414 and T-shaped support plate 416 for horizontal adjustment. The threaded sleeve 414 also simultaneously activates the limit switch. Block 415 slides within the moving groove 3 to ensure the stability of the threaded sleeve block 414. When vertical adjustment is required, the vertical motor 4111 is started to drive the lead screw 418 to rotate. Under the action of the threaded insert seat 417, the lead screw 418, the vertical motor 4111, and the sleeve block 419 will move vertically. When tilt adjustment is required, the double-end motor 4115 is started to drive the rotating shaft and gear 4116 to rotate. Under the action of the semi-circular toothed plate 4117, the gear 4116 moves within the semi-circular toothed plate 4117, ultimately causing the hollow sleeve rod 4114 to rotate within the rotating rod 4113, thus adjusting the tilt of the top positioning cylinder 511, thereby achieving multi-axis adjustment and positioning.
[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
