Description

Technical Field

[0001] The present invention relates to the technical field of gear quality inspection, and in particular to a quality inspection device for gear blank processing. Background Art

[0002] The gear blank is a material that has not yet been processed into teeth. Some of the gear blanks will have an inner ring pre-punched in the middle to facilitate the subsequent installation of the gear. In order to ensure that the ends are neat during subsequent tooth processing, the outer diameter of the gear blank needs to be quality inspected to avoid uneven outer diameters. For example, patent announcement number CN206583389U is a multi-step gear blank outer diameter detection device. The gear blank can be moved along the guide rails by means of a first micrometer, a second micrometer, and a third micrometer arranged on the top of a test plate and a guide rail fixed laterally on the test plate. The first micrometer, the second micrometer, and the third micrometer arranged on the top of the test plate are set at different heights to test the outer diameter dimensions of different steps on the corresponding gear blank respectively.

[0003] However, the above-mentioned detection device can only detect the outer diameter of one side of the gear blank during the quality inspection process. If the gear blank needs to be inspected all around, multiple position adjustments and multiple inspections are required, which makes the quality inspection process more cumbersome. For this reason, the present application designs a quality inspection device for gear blank processing, which can continuously detect the outer diameter of the gear blank and mark unqualified parts without the need for personnel to record by themselves, greatly reducing the personnel operation process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The control gear can be rotated by rotating the first knob, wherein the passive turntable is rotated inside the turntable groove, so that the control gear engages with the tooth groove when rotating, thereby adjusting the rotation angle of the passive turntable and rotating the matching spiral groove on the upper surface of the passive turntable. The first slide and the second slide are provided with matching threads at the bottom to achieve matching with the matching spiral groove and several groups of matching threads. The first slide and the second slide are slidably installed inside the adjustment groove to achieve synchronous adjustment of the positions of the first slide and the second slide to ensure that each supporting shaft can synchronously support the inner ring of the gear embryo, thereby fixing the position of the fixed gear embryo and avoiding errors caused by the movement of the gear embryo during subsequent quality inspection.

[0021] 2. Connect to the external power supply through the conductive track, and use the brush to electrically connect to the conductive track, so that the brush can ensure power transmission when the first slide moves to any position, and cooperate with the wire to ensure power supply to the control motor. When the control motor is started, it can drive the support shaft at the current position to rotate, and the gear blank is supported by the remaining support shafts, so that when one of the support shafts rotates, the gear blank can rotate at an angle, and then cooperate with the quality inspection component to realize continuous quality inspection operation, thereby improving quality inspection efficiency.

[0022] 3. By rotating the first screw rod to engage with the first screw hole thread, the position of the movable support is adjusted by utilizing the limit fit between the movable support and the adjustment slot.

This not only allows the fitting contact rod to adapt to gear blanks of different thicknesses, but also allows corresponding quality inspection operations to be performed on surfaces of different heights of the gear blank.

[0024] 4. When the fitting feeler rod contacts the gear blank protruding from the surface of the gear blank, its protruding part will press the fitting feeler rod, so that the fitting feeler rod will drive the reciprocating rod to move, wherein a first piston is provided at one end of the reciprocating rod, and the gas inside the pressure storage tank will be reduced under the action of the first piston, and under the connection of the interactive pipe, the gas is guided to the inside of the first extension tube, and the first support rod is moved outward, so that the marking paint inside the movable bracket is temporarily attached to the surface of the gear blank, thereby marking the unqualified quality inspection parts, which is not only convenient for subsequent personnel to record but also convenient for subsequent repairs, thereby improving the efficiency of continuous quality inspection, and when the fitting feeler rod is close to the concave part of the gear blank surface, because the fitting feeler rod is not limited at this time, the pressure plate can be pushed by the reset spring, and the gas reflux makes the pressure plate contact with the pressure sensor, thereby controlling the micro air pump to add gas, so that the second support rod extends outward, so that the concave part can also be marked, and the quality inspection effect of this application is not limited to the protruding parts.

[0045] The control gear 503 can be rotated by rotating the first knob 502, wherein the passive turntable 504 is rotated and arranged inside the rotating groove 6, so that the control gear 503 engages with the tooth groove 506 when rotating, thereby adjusting the rotation angle of the passive turntable 504 and rotating the matching spiral groove 505 on the upper surface of the passive turntable 504, wherein the first slide 301 and the second slide 302 are provided with matching threads 304 at the bottom to achieve limited matching between the matching spiral groove 505 and several groups of matching threads 304, and the first slide 301 and the second slide 302 are slidably installed inside the adjusting groove 2 to achieve synchronous adjustment of the positions of the first slide 301 and the second slide 302, so as to ensure that each supporting shaft 303 can synchronously support the inner ring of the gear embryo, thereby fixing the position of the fixed gear embryo and avoiding errors caused by the movement of the gear embryo during the subsequent quality inspection process.

[0046] In this embodiment, the fixing assembly 3 includes a first slide 301 and several second slides 302. The first slide 301 is slidably installed inside one of the adjustment slots 2, and the several second slides 302 are respectively slidably installed inside the remaining adjustment slots 2. The bottom of the first slide 301 and the second slide 302 are both provided with mating threads 304, and each mating thread 304 is slidably engaged with the mating spiral groove 505. The upper ends of the first slide 301 and the second slide 302 are both rotatably provided with support shafts 303.

[0047] It should be noted that a conductive track 7 is provided on the inner wall of one of the adjustment slots 2, a control motor 3013 is fixedly mounted within the first slide 301, the output end of the control motor 3013 being fixedly connected to the adjacent support shaft 303, and a through-hole 3011 is provided on one side of the first slide 301 for staggering the first lead screw 8. The through-hole 3011 allows the first lead screw 8 to be staggered, ensuring that the first lead screw 8 can adjust the position of the movable support 401 and preventing interference from the first slide 301 during the movement of the movable support 401.

[0048] Among them, brushes 3012 are installed on both sides of the first slide 301, the control motor 3013 is electrically connected to the brushes 3012 through the wire 3014, the brushes 3012 are electrically connected to the conductive track 7, and the conductive track 7 is connected to the external power supply through the built-in cable of the placement plate 1.

[0049] It is connected to the external power supply through the conductive track 7, and the brush 3012 is electrically connected to the conductive track 7, so that the first slide 301 can be moved to any position to ensure that the brush 3012 transmits electricity, and cooperates with the wire 3014 to ensure the power supply to the control motor 3013. When the control motor 3013 is started, it can drive the support shaft 303 at the current position to rotate, and the gear embryo is supported by the remaining support shafts 303, so that when one of the support shafts 303 rotates, the gear embryo can rotate at an angle, and then cooperate with the quality inspection component 4 to realize continuous quality inspection operation, thereby improving quality inspection efficiency.

[0050] In this embodiment, the quality inspection component 4 includes a movable support 401, which is slidably installed inside one of the adjustment slots 2. A vertical frame 402 is fixedly installed on the upper end of the movable support 401, a guide rail 4021 is provided on one side of the vertical frame 402, a connecting slide 4031 is slidably installed on the outer side of the guide rail 4021, a placement plate 403 is fixedly installed on one side of the connecting slide 4031, a fixed frame 404 is fixedly installed on one side of the placement plate 403, a main pipe 406 is fixedly installed inside the fixed frame 404, and a fitting touch rod 4061 is provided inside the main pipe 406.

[0051] During the specific setting, a second screw hole 4032 is opened on the plate body of the placement plate 403, a second screw rod 4023 is rotatably installed inside the stand 402, a second knob 4022 is installed on the upper end of the second screw rod 4023, the second screw hole 4032 is threadedly engaged with the second screw rod 4023, and a first screw hole 4011 is opened inside the movable support 401, and the first screw hole 4011 is threadedly engaged with the first screw rod 8.

[0052] By rotating the first screw rod 8 to engage the first screw hole 4011, the position of the movable support 401 is adjusted by utilizing the limited engagement between the movable support 401 and the adjustment slot 2. This allows for quality inspection of gear blanks of different diameters in conjunction with the fixing assembly 3. Furthermore, it ensures that the fitting feeler rod 4061 fits the surface of the gear blank, facilitating subsequent inspections.

[0053] The second screw rod 4023 can be rotated by rotating the second knob 4022, wherein the guide rail 4021 is slidably connected to the connecting slide 4031, so that the height of the mounting plate 403 can be adjusted when the second screw rod 4023 is threadedly engaged with the second screw hole 4032. This not only allows the fitting touch rod 4061 to adapt to gear blanks of different thicknesses, but also allows corresponding quality inspection operations to be performed on surfaces of different heights of the gear blank.

[0054] In the present application, a reciprocating rod 4066 is installed at one end of the fitting touch rod 4061, and a pressure plate 4067 and a first piston 4068 are installed at both ends of the reciprocating rod 4066 respectively. A pressure storage tank 4062 is installed on one side of the main pipe 406, and the first piston 4068 is sealingly and movably arranged inside the pressure storage tank 4062. The pressure plate 4067 is movably arranged inside the main pipe 406 and a return spring 4065 is installed between the inner wall of the main pipe 406 and the pressure plate 4067. An interactive pipe 4063 is provided at the upper end of the pressure storage tank 4062, and a pressure sensor 4064 is installed on one side of the inner wall of the main pipe 406.

[0055] The upper and lower ends of the fixing frame 404 are respectively provided with extension frames 405 , a first extension tube 407 is installed inside the upper extension frame 405 , and a second extension tube 408 is installed inside the lower extension frame 405 ;

[0056] One end of the first extension tube 407 is connected to the interactive pipe 4063. A first support rod 4071 is provided inside the first extension tube 407 for sealing and movement. A spring is provided between the inner wall of the first extension tube 407 and the first support rod 4071. An extension sleeve 4072 is provided on one side of the first extension tube 407. A second piston 4074 is provided inside the extension sleeve 4072 for sealing and movement via a pressure spring 4073.

[0057] A micro air pump 4081 is installed on one side of the second extension tube 408, and the micro air pump 4081 is connected to the pressure sensor 4064 for signal communication. A second support rod 4082 is provided inside the second extension tube 408 in a sealed and movable manner.

[0058] The outer ends of the first support rod 4071 and the second support rod 4082 are both rotatably mounted with movable brackets 409 , and marking paint 410 for marking positions is provided inside the movable brackets 409 .

[0059] When the fitting feeler rod 4061 contacts the protruding gear blank on the surface of the gear blank, its protruding portion presses the fitting feeler rod 4061, so that the fitting feeler rod 4061 drives the reciprocating rod 4066 to move, wherein a first piston 4068 is provided at one end of the reciprocating rod 4066. Under the action of the first piston 4068, the gas inside the pressure storage tank 4062 is reduced, and under the connection of the interactive pipe 4063, the gas is guided into the first extension tube 407, and the first support rod 4071 is moved outward, thereby causing the marking paint 410 inside the movable bracket 409 to temporarily stick to the surface of the gear blank, thereby Marking the unqualified parts of the quality inspection is not only convenient for subsequent personnel to record but also for subsequent repairs, thereby improving the efficiency of continuous quality inspection. Moreover, when the fitting touch rod 4061 is close to the concave part of the gear blank surface, because the fitting touch rod 4061 is not limited at this time, the reset spring 4065 can push the pressure plate 4067, and cooperate with the gas backflow to make the pressure plate 4067 contact with the pressure sensor 4064, thereby controlling the micro air pump 4081 to add air, so that the second support rod 4082 extends outward, so that the concave part can also be marked, thereby improving the quality inspection effect of the present application and not limited to the convex part.

[0060] The different thicknesses of the protruding parts make it difficult to use fixed point calculations, and thus the control method of the pressure sensor 4064 cannot be used. However, when encountering a concave part, the large reserved space allows the fitting feeler rod 4061 to extend outward. When the fitting feeler rod 4061 is extended into position, it can be determined that the current concave part does not meet the subsequent processing requirements of the gear blank, and the position can be marked.

[0061] In order to avoid the gear blank and the fitting contact rod 4061 being stuck due to the internal gas being unable to be released due to the large retraction distance of the fitting contact rod 4061, the first support rod 4071 is pushed outward by the gas. When the first support rod 4071 moves into place, subsequent gas will enter from the expansion sleeve 4072 and push the second piston 4074 to move so that excess gas will enter the expansion sleeve 4072 to ensure that the fitting contact rod 4061 can be smoothly retracted. After the marking is completed, the gas can be discharged back through the pressure spring 4073, so that the fitting contact rod 4061 is reset and fits with the subsequent flat gear blank.

[0062] The working principle of the quality inspection device for gear blank processing:

[0063] When in use, first place the gear blank on the placement plate 1, and then rotate the first knob 502 to rotate the control gear 503, so that the control gear 503 rotates and engages with the tooth groove 506, thereby adjusting the rotation angle of the passive turntable 504, and rotating the matching spiral groove 505 on the upper surface of the passive turntable 504, so that the matching spiral groove 505 and the plurality of matching threads 304 are limitedly matched, and the first slide 301 and the second slide 302 are slidably installed in the adjustment groove 2 to achieve synchronous adjustment of the positions of the first slide 301 and the second slide 302, so that the plurality of supporting shafts 303 can support the inner ring of the gear blank;

[0064] Then, depending on the thickness of the gear blank, the second screw rod 4023 can be rotated by rotating the second knob 4022. The guide rail 4021 is slidably connected to the connecting slide 4031, so that the second screw rod 4023 and the second screw hole 4032 can be threadedly engaged to adjust the height of the placement plate 403, so that the fitting contact rod 4061 is at the required height for quality inspection.

[0065] Then, by rotating the first screw rod 8 to engage with the first screw hole 4011, the position of the movable support 401 is adjusted by utilizing the limited engagement between the movable support 401 and the adjustment slot 2. This allows the fixed component 3 to be used to perform quality inspection on gear blanks of different diameters, and also ensures that the fitting feeler rod 4061 fits the surface of the gear blank.

[0066] After completion, the conductive track 7 is connected to an external power source, and the brush 3012 is electrically connected to the conductive track 7, so that the brush 3012 can ensure power transmission when the first slide 301 moves to any position, and the wire 3014 is used to ensure power supply to the control motor 3013. When the control motor 3013 is started, it can drive the support shaft 303 at the current position to rotate, wherein the gear embryo is supported by the other support shafts 303, so that the gear embryo can rotate angularly when one of the support shafts 303 rotates;

[0067] During the rotation process, the contact rod 4061 cooperates with the concave and convex parts of the gear blank surface, thereby controlling the marking paint 410 inside the movable bracket 409 to be temporarily attached to the gear blank surface. This allows for rapid quality inspection and facilitates subsequent recording and reprocessing by subsequent personnel.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
