Description

Technical Field

[0001] The utility model relates to the field of gear measurement, in particular to a gear inner diameter detection device. Background Art

[0002] A gear is a rotating circular machine part with cut teeth, or in the case of a gear or cogwheel, with inserted teeth (called a pinion), which meshes with another (compatible) toothed part to transfer (convert) torque and speed. Gears may also be informally called cogs. Gearing can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque through their gear ratios, creating a mechanical advantage, and can therefore be considered simple machines. The speed and torque of two meshing gears differ in proportion to their diameters. The shape of the teeth on both meshing gears is the same.

[0003] After a gear has been used for a period of time, it will deform due to long-term stress. If it is not discovered in time during maintenance, the gear will be damaged and the mechanical synchronization using the gear will be damaged. Therefore, gears in some important positions need to be regularly inspected. However, the traditional method of detecting the inner and outer ring sizes of gears mostly uses vernier calipers or micrometers, which are not only cumbersome to operate but also affected by the teeth on the gear. The accurate reading needs to be affected by repeated measurements, the operation is very complicated, and the function is single, which is not easy to carry.

[0004] Therefore, it is necessary to propose a gear inner diameter detection device to solve the above problems. Utility Model Content

[0009] Preferably, an annular groove is formed at one end of the fixed grip tube away from the first clamping member, an annular tooth is fixedly installed inside the annular groove, a cross bar is fixedly installed inside the fixed groove, support blocks are fixedly installed at both ends of the cross bar, a second support rod is fixedly installed on the upper surface of the support block, a micro gear is rotatably installed on the top end of the second support rod, and the micro gear extends to the inside of the annular groove and meshes with the annular tooth.

[0010] Preferably, a screw rod is threadedly connected to a side of the support block away from the second support rod, and one end of the screw rod extends to the surface of the micro gear.

[0011] Preferably, the first slide groove is in an arc shape, and the second slide groove is in a straight line shape.

[0012] Technical effects and advantages of the utility model:

[0013] By setting the second clamp and the first clamp, the device can measure not only the inner ring gear of the gear, but also the outer ring size of the gear. The device has diversified functions, is light and compact, has a volume of about the size of a palm, has a regular shape, and is easy to carry. It is more convenient for the detection of mechanical gears in the later stage, makes the maintenance work faster, thereby reducing the maintenance period and reducing the equipment downtime.

[0014] By setting up multiple measuring parts, the reading change of the scale line can be observed by rotating the gear. The wear condition of the gear can be obtained through the reading change of the scale line, avoiding the situation of inadequate measurement and ensuring the normal operation of the machine.

[0015] When measuring, the screw can be rotated, and the screw moves toward the micro-gear, thereby holding the micro-gear. At this time, the micro-gear cannot rotate, and the second clamp cannot rotate, so that all measuring parts are fixed, and the scale line reading is latched. At this time, the gear can be rotated. If the gear cannot rotate, it means that the gear is deformed or the production process is unqualified. The latched device can also be moved to the next test location for comparison with other gears. It can intuitively show whether there are differences between multiple gears. If one of the gears cannot be adapted, it means that the gear at that location is faulty. It has diverse functions and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-6 A gear inner diameter detection device shown in the figure includes a fixed gripping cylinder 1, a first clamping member 2 is fixedly installed on the upper surface of the fixed gripping cylinder 1, a second clamping member 3 is arranged above the first clamping member 2, a plurality of evenly distributed first slide grooves 201 are opened on the first clamping member 2, the shape of the first slide groove 201 is arc-shaped, a plurality of second slide grooves 301 corresponding to the first slide grooves 201 are opened on the second clamping member 3, the shape of the second slide grooves 301 is straight, the first slide groove 201 is arc-shaped and the second slide groove 301 is straight, so that when the second clamping member 3 rotates, the colinear workpieces on the first clamping member 2 and the second clamping member 3 will generate a force to move along the second slide groove 301, thereby converting the rotational force into kinetic energy for linear movement.

[0025] A plurality of scale lines 302 corresponding to the second slide groove 301 are provided on the upper surface of the second clamping member 3, and a measuring abutment 4 is provided inside each of the plurality of second slide grooves 301. The measuring abutment 4 comprises a slider 401, and the slider 401 is slidably clamped inside the second slide groove 301, a slide column 402 is fixedly installed on the lower surface of the slider 401, a first support rod 403 is fixedly installed on the upper surface of the slider 401, a micro pulley 404 is rotatably installed on the top end of the first support rod 403, and the slide column 402 is movably clamped inside the corresponding first slide groove 201.

[0026] When in use, first put the gear on the outside of all the measuring resisters 4, and then rotate the second clamping member 3. At this time, the slide column 402 will move along the first slide groove 201, and the second slide groove 301 limits the moving direction of the slider 401, so that the measuring resister 4 as a whole will only produce horizontal movement force, so rotating the second clamping member 3 will drive all the measuring resisters 4 to move away from each other until the micro pulley 404 is resisted by the inner ring of the gear. At this time, the reading corresponding to the farthest end of the slider 401 is the radius of the inner ring of the gear. Recording the readings of all the scale lines 302 and taking the average value is the most accurate gear inner ring size. During measurement, the gear can also be rotated to observe the changes in the readings. If the readings change significantly, it means that the gear has undergone a large deformation and needs to be replaced in time.

[0027] The device can not only measure the inner ring size of the gear, but also the outer ring size of the gear. When in use, rotate the second clamp 3 to move the measuring abutment 4 to the maximum position, then place the gear at the center of the upper surface of the second clamp 3, and slowly rotate the second clamp 3 in the opposite direction. At this time, multiple measuring abutments 4 move toward each other until the micro pulley 404 is abutted by the outer ring of the gear. At this time, the reading corresponding to the nearest side of the slider 401 is the outer ring radius of the gear. Reading the readings of all scale lines 302 and taking the average value is the most accurate outer ring radius of the gear. Similarly, during measurement, the gear can be rotated to observe whether the reading changes. If the change is too large, it means that the gear teeth are highly worn, and the gear needs to be replaced immediately.

[0028] By setting the second clamp 3 and the first clamp 2, the device can measure not only the inner ring gear of the gear, but also the outer ring size of the gear. The device has diversified functions, is light and compact, has a volume about the size of a palm, has a regular shape, and is easy to carry. It is more convenient for the detection of mechanical gears in the later stage, makes the maintenance work faster, thereby reducing the maintenance period and reducing the equipment downtime.

[0029] By setting up multiple measuring members 4, the reading change of the scale line 302 can be observed by rotating the gear. The wear condition of the gear can be obtained through the reading change of the scale line 302, avoiding the occurrence of inadequate measurement and ensuring the normal operation of the machine.

[0030] A center column 303 is fixedly installed in the middle of the lower surface of the second clamping member 3, and a fixing groove 304 is provided at one end of the center column 303 away from the second clamping member 3. A cross bar 5 is fixedly installed inside the fixing groove 304, and support blocks 501 are fixedly installed at both ends of the cross bar 5. A middle groove 103 is provided in the middle of the fixed grip tube 1, and the center column 303 passes through the first clamping member 2 and is rotatably clamped inside the middle groove 103.

[0031] An annular groove 101 is provided at one end of the fixed grip 1 away from the first clamping member 2, and an annular tooth 102 is fixedly installed inside the annular groove 101. A second support rod 502 is fixedly installed on the upper surface of the support block 501, and a micro gear 503 is rotatably installed on the top of the second support rod 502. The micro gear 503 extends to the inside of the annular groove 101 and meshes with the annular tooth 102. A screw 504 is threadedly connected to one side of the support block 501 away from the second support rod 502, and one end of the screw 504 extends to the surface of the micro gear 503.

[0032] When measuring, the screw 504 can be rotated, and the screw 504 moves toward the micro gear 503, thereby pressing the micro gear 503. At this time, the micro gear 503 cannot rotate, and the second clamp 3 cannot rotate, so that all the measuring members 4 are fixed, and the reading of the scale line 302 is latched. At this time, the gear can be rotated. If the gear cannot rotate, it means that the gear is deformed or the production process is unqualified. The latched device can also be moved to the next test location for comparison with other gears. It can intuitively show whether there are differences between multiple gears. If one of the gears cannot be adapted, it means that the gear at that location is faulty. It has diverse functions and strong practicality.
