Description

Technical Field

[0001] This application relates to the technical field of gear blank detection, and particularly to a device for detecting the thickness of gear blanks. Background Art

[0002] The engine gear blank is the initial form of engine gear manufacturing and also the basis for subsequent processing operations. Its quality directly affects the key performance of the final engine gear, such as accuracy, strength, wear resistance, etc., and further affects the overall performance and reliability of the engine.

[0003] Currently, for the detection method of the thickness of gear blanks, usually, an operator uses a vernier caliper or a micrometer to detect its thickness. Both the vernier caliper and the micrometer require the operator to measure the gear blank at multiple points, and then compare the measured values with the qualified range values of the product. Those within the range are qualified products, and those outside the values are unqualified products.

[0004] However, although these detection methods meet the detection requirements of gear blanks to a certain extent, their operation processes are cumbersome and the efficiency is not high. Utility Model Content

[0005] In order to improve the detection efficiency, this application provides a device for detecting the thickness of gear blanks.

[0006] The device for detecting the thickness of gear blanks provided by this application adopts the following technical solutions:

[0007] A device for detecting the thickness of gear blanks includes a working plate and a support plate detachably connected to one end of the working plate. The working plate is respectively provided with a go gauge column and a no-go gauge column. The go gauge column is located above the no-go gauge column. The gap between the go gauge column and the working plate is greater than the gap between the no-go gauge column and the working plate. When the gear blank slides down贴面 from above the working plate, if the gear blank passes through the gap between the go gauge column and the working plate and does not pass through the gap between the no-go gauge column and the working plate, it is a qualified part. ]

[0008] By adopting the above technical solutions, the operator first places the detection device on the workbench, and then slides the gear blank down贴面 from above the working surface of the working plate. When the gear blank passes through the gap between the go gauge column and the working plate and does not pass through the gap between the no-go gauge column and the working plate, this gear blank is a qualified part. When the gear blank does not pass through the gap between the go gauge column and the working plate or passes through the gap between the no-go gauge column and the working plate, it is an unqualified part. The operator takes it out and collects it uniformly. Thus, the detection efficiency of gear blanks is greatly improved.

[0009] Optionally, a guiding inclined surface is provided on one side of the no-go gauge column close to the go gauge column, and a buffer pad is provided on the guiding inclined surface.

[0010] By adopting the above technical solution, the guide ramp can guide qualified gear blanks to fall into the designated qualified product placement area according to the angle of its ramp, which further improves the efficiency of the detection device, while the buffer pad can protect the falling gear blanks, thereby ensuring the accuracy requirements of the gear blanks.

[0011] Optionally, anti-slip pads are provided at the opposite ends of the work plate and the support plate.

[0012] By adopting the above technical solution, when the worker places the testing device on the workbench, the protective pad can increase the friction between the work plate and the support plate and the workbench, thereby improving the stability of the testing device.

[0013] Optionally, the go gauge includes a connecting plate and pads detachably connected to both ends of the connecting plate, the pads being located between the connecting plate and the working plate; the no-go gauge includes a stop plate and pads detachably connected to both ends of the stop plate, the pads being located between the stop plate and the working plate.

[0014] By adopting the above technical solution, operators can adjust the gap between the connecting plate and the working plate and the gap between the abutment plate and the working plate by increasing or decreasing the number of pads and blocks, thereby improving the adaptability of the detection device.

[0015] Optionally, a sliding groove is provided on the working plate, and the go gauge and no-go gauge are slidably disposed in the sliding groove. The go gauge includes a lifting plate and a lifting block connected to the lifting plate. The no-go gauge includes a blocking plate and a blocking block connected to the blocking plate. An adjustment groove is provided on both the lifting block and the blocking block. An adjustment component is provided in each adjustment groove. The adjustment component is used to adjust the movement of the lifting block and the blocking block along the vertical direction of the sliding groove.

[0016] By adopting the above technical solution, the operator can adjust the components to make the lifting block and the blocking block move along the vertical direction of the sliding groove, thereby realizing the gap between the working plate and the lifting plate and the blocking plate, thus improving the adaptability of the detection device.

[0017] Optionally, a drive shaft and a driven shaft are rotatably connected to both the lifting block and the blocking block. Limiting annular grooves are formed on both the lifting block and the blocking block, and ball bearings are installed within these grooves. The limiting annular grooves communicate with an adjusting groove. The ball bearings are fixedly sleeved on the driven shaft. The axes of the drive shaft and the driven shaft are arranged perpendicularly to each other. Both the drive shaft and the driven shaft pass through the adjusting groove. The adjusting assembly includes a first interlaced gear and a second interlaced gear. The first interlaced gear is sleeved on the drive shaft, and the second interlaced gear is sleeved on the driven shaft. The driven shaft passes through the adjusting groove and extends towards the bottom of the sliding groove on the work plate. A bolt is connected to the end of the driven shaft away from the second interlaced gear, and the bolt is threadedly connected to the work plate.

[0018] By adopting the above technical solution, the operator rotates the driving shaft to make the first staggered gear rotate, thereby driving the second staggered gear to rotate. At this time, the driven shaft also rotates accordingly, and then drives the bolt to rotate. The outer diameter of the ball bearing is fixedly connected to the lifting block or the blocking block, and the inner diameter is fixedly sleeved on the driven shaft, so that the driven shaft is fixed and rotationally connected to the lifting block or the blocking block. Since the bolt is threadedly connected to the working plate and the bolt is fixedly connected to the driven shaft, the lifting block and the blocking block can move up and down along the vertical direction of the sliding groove, making it more convenient for the staff to adjust the gap between the working plate, the lifting plate and the blocking plate, thus greatly improving the efficiency of the detection device.

[0019] Optionally, limiting grooves are provided on both the lifting block and the blocking block. The limiting grooves are communicated with the adjusting grooves, and a dust-proof plate is provided in the limiting grooves.

[0020] By adopting the above technical solution, the dust-proof plate can reduce the possibility of dust entering the adjustment part, thereby increasing the service life of the detection device.

[0021] Optionally, thumb grooves are provided on both the lifting block and the blocking block. The thumb grooves are communicated with the limiting grooves.

[0022] By adopting the above technical solution, the function of the thumb grooves can make it more convenient for the operator to take the dust-proof plate, and also further improve the disassembly and maintenance efficiency.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The operator first places the detection device on the workbench, and then slides the gear blank from above and贴面 (it seems there is a wrong word here, maybe "face-to-face") of the workbench surface. When the gear blank passes through the gap between the go gauge bar and the workbench and does not pass through the gap between the no-go gauge bar and the workbench, then this gear blank is a qualified part. When the gear blank does not pass through the gap between the go gauge bar and the workbench or passes through the gap between the no-go gauge bar and the workbench, it is an unqualified part, and the operator takes it out and collects it uniformly. Thus, the detection efficiency of the gear blank is greatly improved;

[0025] 2. The operator can adjust the gap between the connecting plate and the workbench and the gap between the abutting plate and the workbench by increasing or decreasing the number of spacer plates and cushion blocks, thereby improving the adaptability of the detection device;

[0026] 3. The operator rotates the drive shaft, causing the first interlocking gear to rotate, which in turn drives the second interlocking gear to rotate. The driven shaft also rotates, causing the bolt to rotate. Because the bolt is threaded to the work plate and fixedly connected to the driven shaft, the lifting block and the blocking block can move vertically up and down along the sliding groove. This makes it easier for the operator to adjust the gap between the work plate and the lifting and blocking plates, thus greatly improving the efficiency of the testing device.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a gear blank thickness detection device.

[0035] Example 1

[0036] Reference Figure 1A gear blank thickness inspection device includes a working plate 2 and a support plate 1 detachably connected to one end of the working plate 2 by countersunk bolts. The working plate 2 is provided with a go gauge 21 and a no-go gauge 22, with the go gauge 21 located near the connection between the working plate 2 and the support plate 1 and above the no-go gauge 22. The gap between the go gauge 21 and the working plate 2 is greater than the gap between the no-go gauge 22 and the working plate 2. When the operator slides the gear blank from above the working plate 2, if the gear blank passes through the gap between the go gauge 21 and the working plate 2 but fails to pass through the gap between the no-go gauge 22 and the working plate 2, it is considered a qualified part. The operator only needs to lower the gear blank from above the working plate 2, thus greatly improving the inspection efficiency of the gear blank.

[0037] Reference Figure 1 The stop gauge 22 has a guide ramp 23 on the side near the go gauge 21, which allows qualified gear blanks to fall into the qualified product storage area under the guidance of the guide ramp 23, further improving inspection efficiency. Furthermore, a buffer pad 231 is detachably connected to the guide ramp 23. When a qualified gear blank passes through the gap between the go gauge 21 and the working plate 2, it will be blocked by the stop gauge 22, while the buffer pad 231 reduces the possibility of damage to the qualified gear blank, thus ensuring the accuracy requirements of the gear blank.

[0038] Reference Figure 1 The working plate 2 and the support plate 1 are fixedly connected to an anti-slip pad 6 at the end away from the connection point. When the operator places the testing device on the workbench, the anti-slip pad 6 reduces the possibility of the testing device shifting during the testing process, thereby improving work efficiency.

[0039] Reference Figure 1 The go gauge 21 includes a connecting plate 211 and pads 212 detachably connected to both ends of the connecting plate 211 by countersunk bolts. The no-go gauge 22 includes a stop plate 221 and pads 222 detachably connected to both ends of the stop plate 221 by countersunk bolts. The pads 212 and 222 are located between the working plate 2 and the connecting plate 211 and the stop plate 221, respectively. Furthermore, the operator can adjust the gap between the no-go gauge 22 and the go gauge 21 and the working plate 2 by increasing the number of pads 212 or 222 according to the requirements of different models. This improves the adaptability of the testing device.

[0040] The implementation principle of this embodiment 1 is as follows:

[0041] When the operator needs to inspect the thickness of the gear blank, the inspection device is first placed on the workbench. At this time, the anti-slip pad 6 can reduce the possibility of the inspection device sliding during inspection.

[0042] Secondly, the operator needs to determine the maximum and minimum thickness based on the qualification standards of the gear blank. The gap between the go gauge 21 and the working plate 2 is the maximum value of the gear blank, and the gap between the no-go gauge 22 and the working plate 2 is the minimum value of the gear blank.

[0043] After adjustment, the operator slides the gear blank to be inspected from the top of the work plate 2. Qualified gear blanks pass through the go gauge 21 and are blocked by the no-go gauge 22, then slide down the guide ramp 23 to the qualified product storage area. Gear blanks that fail to pass through the go gauge 21, or those that pass through both the go and no-go gauges 22, are deemed unqualified. This improves the inspection efficiency of the testing device, while the buffer pad 231 of the guide ramp 23 reduces the possibility of the gear blank's accuracy being reduced due to impacts.

[0044] Example 2

[0045] Reference Figures 2 to 5 The working plate 2 has a sliding groove 24, and the go gauge 21 and the no-go gauge 22 are slidably connected within the sliding groove 24. The go gauge 21 includes a lifting plate 213 and a lifting block 214 fixedly connected to the lifting plate 213. The no-go gauge 22 includes a blocking plate 223 and a blocking block 224 fixedly connected to the blocking plate 223. Both the lifting block 214 and the blocking block 224 have an adjustment groove 3, and each adjustment groove 3 has an adjustment component 4, which includes a first interlaced gear 41 and a second interlaced gear 42. Both the lifting block 214 and the blocking block 224 are rotatably connected to a drive shaft 31 and a driven shaft 32. Both the lifting block 214 and the blocking block 224 have a limit ring groove 7, which communicates with the adjustment groove 3. A ball bearing 71 is fixedly installed in the limit ring groove and is fixedly sleeved on the driven shaft 32. The axis of the drive shaft 31 and the axis of the driven shaft 32 are alternately and perpendicularly arranged. The first interlaced gear 41 is fixedly sleeved on the drive shaft 31, and the second interlaced gear 42 is fixedly sleeved on the driven shaft 32. The end of the drive shaft 31 away from the first interlaced gear 41 passes through the adjusting groove 3 and extends to the outside of the lifting block 214. A rotating knob 311 is fixedly connected to the end of the drive shaft 31 away from the lifting block 214, and the rotating knob 311 has anti-slip texture. The end of the driven shaft 32 away from the adjusting groove 3 passes through the lifting block 214, and a bolt 321 is fixedly connected to the end of the driven shaft 32 away from the second interlaced gear 42. The bolt 321 is threadedly connected to the working plate 2.

[0046] Reference Figure 2 and Figure 5When operators need to adjust gear blanks of different models, they only need to adjust the rotary knob 311 to drive the drive shaft 31 to rotate. The anti-slip texture on the rotary knob 311 increases the friction during adjustment, reducing the possibility of slippage. When the drive shaft 31 rotates, it drives the first interlocking gear 41 to rotate synchronously. The rotation of the first interlocking gear 41 drives the second interlocking gear 42, which meshes with it, to rotate. The rotation of the second interlocking gear 42 drives the driven shaft 32, which is coaxially fixed to it, to rotate synchronously. This drives the bolt 321, which is coaxially fixed to it, to rotate. Since the inner diameter of the ball bearing 71 is fixedly sleeved on the driven shaft 32, and the outer diameter of the ball bearing 71 is fixedly connected to the lifting block 214, the rotation of the bolt 321 enables the lifting block 214 to move up and down. Ultimately, the go gauge 21 and the no-go gauge 22 can move up and down along the vertical direction of the sliding groove 24, thereby adjusting the gap between the go gauge 21 and the no-go gauge 22 and the working plate 2, so that the detection device can meet the thickness detection of gear blanks of different models.

[0047] Reference Figure 2 and Figure 3 Both the lifting block 214 and the blocking block 224 are equipped with scales 25, which makes it more accurate for the staff to adjust the gap between the go gauge 21 and the stop gauge 22 and the working plate 2, greatly improving the detection accuracy.

[0048] Reference Figure 2 , Figure 3 and Figure 5 Both the lifting block 214 and the blocking block 224 have limit grooves 5, which communicate with the adjusting groove 3. A dust cover 51 is detachably connected to the limit groove 5. The dust cover 51 can reduce the possibility of dust entering the adjusting groove 3 and causing the first interlocking gear 41 and the second interlocking gear 42 to jam. The dust cover 51 also improves the efficiency of the operator's subsequent maintenance of the detection device. Both the lifting block 214 and the blocking block 224 have thumb grooves 52, which communicate with the limit grooves 5, making it easy for the operator to install and remove the dust cover 51, thereby improving the efficiency of subsequent maintenance.

[0049] The implementation principle of Embodiment 2 of this application is as follows:

[0050] The operator rotates the rotary knob 311 on the drive shaft 31, causing the first interlaced gear 41 to rotate along with the drive shaft 31. The rotation of the first interlaced gear 41 then drives the driven shaft 32 and bolt 321 to rotate. Since the thread is threadedly connected to the working plate 2, the gap between the go gauge 21 and the no-go gauge 22 and the working plate 2 is adjusted, thereby improving the adaptability of the detection device.

[0051] The scale 25 on the blocking block 224 and the lifting block 214 can improve the accuracy of the operator when adjusting the gap between the go gauge 21 and the stop gauge 22 and the working plate 2, which greatly improves the detection accuracy.

[0052] The dust shield 51 can reduce the possibility of dust entering the adjustment groove 3, thereby reducing the possibility of the first interlocking gear 41 and the second interlocking gear 42 getting stuck due to dust. The thumb groove 52 can improve the maintenance efficiency of the detection device by the operators in the later stage.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
