The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] According to an embodiment of the utility model, an inner diameter measuring device for gear ring production is provided.

[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, the inner diameter measuring device for gear ring production according to the embodiment of the utility model includes a workbench 1, a top plate 2 is arranged at the top of the workbench 1, a gear ring clamping mechanism 3 is arranged inside the workbench 1, and the top of the gear ring clamping mechanism 3 extends to the top of the top plate 2, and a avoidance opening is arranged on the top plate 2, so that the gear ring clamping mechanism 3 can move normally; a rotating support mechanism 4 is arranged in the middle of the top plate 2, a mounting frame 5 is arranged at the top of the rotating support mechanism 4 and located at the top of the top plate 2, an inner diameter measuring assembly 6 is arranged in the middle of the mounting frame 5, and the bottom end of the inner diameter measuring assembly 6 extends to the middle top of the rotating support mechanism 4.

[0027] With the aid of the above scheme, the utility model can measure the inner diameter of the gear ring. Through the non-contact measurement method and the design of fixing the gear ring, the influence of the gear ring rotating under external influence on the measurement accuracy is eliminated, thereby ensuring the accuracy of the inner diameter measurement.

[0028] In one embodiment, for the above-mentioned ring gear clamping mechanism 3, the ring gear clamping mechanism 3 includes a rotating rod 301 arranged in the middle of the workbench 1, both ends of the rotating rod 301 are connected to one end of the connecting rod 302, the other end of the connecting rod 302 is connected to a driving plate 303, one end of the driving plate 303 is connected to a power assembly, a slider 304 is arranged at the bottom end of the driving plate 303, and a slide rail 305 is arranged at the bottom end of the slider 304; a vertical plate 306 is arranged at the top end of the driving plate 303, the top end of the vertical plate 306 passes through the top plate 2 and extends to the top of the top plate 2, and the vertical plate 306 is provided at the top end of the driving plate 303. A clamping block 307 is provided at the top of the plate 306; a soft pad 308 is provided at one end of the clamping block 307 close to the middle of the rotating support mechanism 4, and the soft pad 308 is an arc-shaped structure; the power component includes an electric cylinder mounting plate 309 arranged in the workbench 1, and an electric cylinder 310 is provided on the side wall of the electric cylinder mounting plate 309, and the output shaft of the electric cylinder 310 is connected to the end of the driving plate 303, so as to realize automatic clamping and loosening of the gear ring operation, ensure that the gear ring does not rotate during the measurement process, and improve the operation efficiency and accuracy. The design of the soft pad 308 protects the surface of the gear ring to avoid damage.

[0029] The working principle of the gear ring clamping mechanism 3 is as follows: start the electric cylinder 310, the output shaft of the electric cylinder 310 drives the driving plate 303 to move, and the slider 304 at the bottom of the driving plate 303 slides on the slide rail 305, thereby realizing horizontal movement. And through the drive of the electric cylinder 310, the clamping block 307 approaches or moves away from the gear ring to realize automatic clamping and loosening operations. When the clamping block 307 approaches the gear ring, the soft pad 308 contacts the surface of the gear ring to evenly distribute the pressure and avoid damage to the gear ring. At the same time, the design of the rotating rod 301 and the connecting rod 302 enables the two groups of clamping blocks 307 to move synchronously in opposite directions to achieve clamping and loosening of the gear ring. The fixed gear ring remains stable and will not rotate during the measurement process, ensuring the measurement accuracy.

[0030] In one embodiment, for the above-mentioned rotating support mechanism 4, the rotating support mechanism 4 includes a motor 401 arranged in the middle of the top plate 2, and a gear ring placement frame 402 is arranged at the top end of the output shaft of the motor 401; the gear ring placement frame 402 is a cross-shaped structure, and four positioning bearings 403 are arranged at the top end of the gear ring placement frame 402, so that the gear ring can be accurately positioned at the measuring position, and can drive the gear ring to rotate, and then the inner diameter measuring component 6 can measure the inner diameter of the gear ring in different directions.

[0031] In addition, a plurality of mounting holes may be provided on the gear ring placement frame 402 so that the positioning bearing 403 can be installed at different positions, thereby being suitable for gear rings of different sizes.

[0032] The working principle of the rotating support mechanism 4 is as follows: after the inner wall of the gear ring is placed outside the four positioning bearings 403, if the gear ring does not need to be rotated, the gear ring is clamped by the gear ring clamping mechanism 3, and if the gear ring needs to be rotated, the gear ring clamping mechanism 3 releases the gear ring. The motor 401 is started, and the output shaft of the motor 401 is connected to the gear ring placement frame 402, thereby driving the gear ring placement frame 402 and the gear ring to rotate, so that the inner diameter measuring assembly 6 can measure the inner diameter of the gear ring in different directions.

[0033] In one embodiment, for the above-mentioned inner diameter measuring component 6, the inner diameter measuring component 6 includes a slide groove 601 set in the middle of the mounting frame 5, a square plate 602 is slidably arranged in the slide groove 601, a baffle 603 is arranged at the top of the square plate 602, and a distance sensor 604 is arranged at the bottom of the square plate 602, so that the inner diameter of the gear ring can be accurately measured, and the square plate 602 and the distance sensor 604 can rise and fall, so that there will be no obstruction when placing or removing the gear ring.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] In actual application, if a gear ring (such as an ABS gear ring) is placed or removed, the square plate 602 and the distance sensor 604 are lifted, and then the square plate 602 and the distance sensor 604 are lowered. The gear ring is driven to rotate by the rotating support mechanism 4, and the gear ring is clamped by the gear ring clamping mechanism 3 after rotation. Then the inner diameter of the gear ring is measured by the distance sensor 604. High-precision, non-contact measurement of the inner diameter of the gear ring is achieved. The motor 401 and the electric cylinder 310 are connected to an external power supply to obtain the electrical energy required for operation, and are connected to an external control panel to receive control instructions. The motor 401 can use a reduction motor, which is more stable when rotating the gear ring placement frame 402 and the gear ring.

[0036] The distance measuring sensor 604 is started to measure the inner diameter of the gear ring in a non-contact manner. The distance measuring sensor 604 uses a laser distance measuring sensor to determine the distance between the target object and the sensor by emitting a laser pulse and measuring the time it takes for it to reflect back. The structure of the laser distance measuring sensor includes a laser, a receiver, a signal processing circuit, etc. When measuring the inner diameter of the gear ring, the starting position of the laser distance measuring sensor should be located at one end point of the inner diameter of the gear ring, and the laser beam is perpendicular to the inner diameter surface. The measuring axis of the sensor is parallel to the diameter line of the inner diameter of the gear ring.

[0037] In summary, the utility model can measure the inner diameter of the gear ring. Through the non-contact measurement method and the design of fixing the gear ring, the influence of the gear ring on the measurement accuracy when it rotates due to external influences is eliminated, thereby ensuring the accuracy of the inner diameter measurement. By setting the gear ring clamping mechanism 3, the operation of clamping and releasing the gear ring can be realized automatically, ensuring that the gear ring does not rotate during the measurement process, and improving the operation efficiency and accuracy. The design of the soft pad 308 protects the surface of the gear ring and avoids damage. By setting the rotating support mechanism 4, the gear ring can be accurately positioned at the measurement position, and can drive the gear ring to rotate, so that the inner diameter measurement component 6 can measure the inner diameter of the gear ring in different directions. By setting the inner diameter measurement component 6, the inner diameter of the gear ring can be accurately measured, and the square plate 602 and the distance sensor 604 can rise and fall, so that when placing or removing the gear ring, it will not be hindered.
