Description

Technical Field

[0001] The present invention relates to the technical field of positioning jigs, and more particularly to a positioning device for machining parts of a power take-off Background Art

[0002] A power take-off is a set of one or more speed-changing gears, also known as a power take-off. Generally, it is composed of a gearbox, a clutch, and a controller. It is connected to the low-speed gear of the gearbox or the output shaft of the auxiliary box, and is connected to the input shaft of a power take-off device such as a lift pump. It is a separate gear position in the gearbox. When the gear is engaged and the accelerator is pressed, the lift pump can operate. Generally, when machining parts of a power take-off, drilling needs to be performed on the parts of the power take-off.

[0003] Chinese Utility Model with publication number CN212793153U discloses a positioning device for machining parts of a power take-off. One end of the support frame is provided with a sliding hole. The inner wall of the sliding hole is symmetrically and fixedly connected with first guide rods. The outer ends of the first guide rods are slidably connected with first sliders. One end of the first slider is rotatably connected with a first screw rod. The first screw rod is rotatably connected with a second slider. The two sides of the top of the support frame are equidistantly provided with positioning holes. The positioning holes are internally clamped with positioning pins. The structure of the present invention is scientific and reasonable, and it is safe and convenient to use. It is provided with first guide rods, first sliders, first screw rods, second sliders, positioning holes, and positioning pins. Through the first guide rods, it is convenient for the first sliders to move, so as to facilitate the longitudinal movement of the drill bit. Through the first screw rods, it is convenient for the second sliders to move, so as to facilitate the positioning of the parts, and further facilitate the drill bit to process at any position on the surface of the parts.

[0004] It can be seen that currently, for workpieces that require high-precision hole machining such as power take-off parts, the method of two-way clamping or three-jaw clamping is usually still used for fixation. This fixation method requires a high-precision machine tool to achieve. For non-standard special-shaped position holes, such as inclined straight holes on large parts, the current fixation method cannot achieve high-precision drilling well. It is not easy to quickly find and locate the center point of drilling during drilling. At the same time, due to the too high precision requirement standard, when the drill bit does not match the material or the feed force and rotational speed are not coordinated during current drilling, vibration of the drill bit is likely to occur. There is currently no good precise detection means to ensure the coordination of the feed force and rotational speed all the time and machine high-precision holes. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning device for machining parts of a power take-off to solve the problems existing in the above background art.

[0006] The present invention provides the following technical solution: A positioning device for the processing of power take-off parts, including a support outer ring. The support outer ring includes a support main ring. Four clamping grooves are provided at the bottom of the support main ring, and two groups of hexagonal positioning holes are provided at the top of the support main ring. Each group includes 3 individual hexagonal positioning holes. A positioning component is installed on one group of hexagonal positioning holes. A cooling component is installed at the bottom of the positioning component, and a reflective component is installed on the side of the positioning component. A plurality of arc plate storage grooves are provided at the top of the support main ring. The number of arc plate storage grooves is the same as the number of precise light emitters. A photosensitive arc plate is installed inside the arc plate storage groove, and the photosensitive arc plate is used to collect the light of the precise light emitter;

[0007] The transmission component includes a transmission rod. A rotating sub-plate is fixedly connected to the side of the transmission rod, and a transmission gear is fixedly connected to the top of the transmission rod. The amplifier includes an amplification gear. A double-headed light emitter is installed at the bottom of the amplification gear. The double-headed light emitter consists of two light sources distributed in a V shape. The light rays emitted by the two light sources form an asymmetric light spot on the photosensitive straight plate. The deviation size of the clamping position is obtained by calculating the difference of the light spot center points.

[0008] Further, the moving box is installed on the side of the support main ring. An adjusting rod is sleeved on the side of the moving box. A transverse push plate and a first spring are respectively installed on both sides of the moving box on the adjusting rod. The transverse push plate is threadedly connected to the adjusting rod. The first spring is sleeved on the adjusting rod. When the adjusting rod rotates, the adjusting rod drives the transverse push plate to push the moving box towards the center. When the adjusting rod rotates in the reverse direction, the first spring pushes the moving box to move in the reverse direction. A photosensitive straight plate is installed on the side of the moving box. A transmission component is installed inside the moving box. The side of the transmission component is meshed with an amplifier. A clamping touch plate is installed at the bottom of the side of the moving box. The clamping touch plate is installed on the side of the moving box through a spring. Two deep holes are provided on the side of the clamping touch plate. A touch ball rod is installed inside the deep holes. One end of the touch ball rod is installed on the rotating sub-plate.

[0009] Further, the positioning component includes a drilling ring. A plurality of placement grooves are provided on the side of the drilling ring. A reflective component is installed inside the placement grooves. Arc-shaped outer grooves are provided on both sides of the placement grooves. Arc-shaped covers are installed inside the arc-shaped outer grooves. The arc-shaped covers are used to cover and protect the reflective component after use. Three radiation support plates are fixedly connected to the side of the drilling ring. The bottom of the terminal of the radiation support plate is fixedly connected to a positioning short rod. The positioning short rod is installed inside the hexagonal positioning hole. Between the plurality of positioning short rods is used to fix the processing point positions. A moving groove is provided inside the drilling ring. The cooling component is installed on the moving groove. When in use, the height position of the inclined nozzle is adjusted by sliding up and down in the moving groove.

[0010] Furthermore, the reflective component includes a reflector and a shock-sensitive arc plate. The reflector and the shock-sensitive arc plate are connected by a buffer spring. The reflector is installed on the placement groove, and the shock-sensitive arc plate is installed on the inner diameter side of the drilling ring. When vibration occurs, the light emitted by the precise light emitter is reflected by the reflector onto the photosensitive arc plate, and the shock-sensitive arc plate judges the vibration situation by detecting the vibration frequency and amplitude of the light.

[0011] Furthermore, the cooling component includes a water tank. A positioning inner ring is fixedly connected to the top of the water tank. The positioning inner ring is installed inside the moving groove. A water storage cavity is formed inside the side of the water tank. The outside of the water storage cavity is communicated with the connecting head. A plurality of bevel nozzles are installed at the bottom of the water tank. The bevel nozzles are installed obliquely, and the inclination angles of the plurality of bevel nozzles all face the edge of the hole processing position.

[0012] Furthermore, an information collection unit and a central control unit are installed inside the support outer ring. The information collection unit collects the light information of the photosensitive straight plate, calculates the central position difference through the deviation of the two lights of the double-headed light emitter, and the central control unit controls the rotation angles of the two side adjusting rods to achieve high-precision positioning of the center through multiple feedbacks.

[0013] Furthermore, the inner diameter size of the drilling ring has multiple models. During processing, the shaft hole is processed by selecting a suitable inner diameter. Square grooves are formed on the radiation support plate, and scales are arranged inside the square grooves.

[0014] Furthermore, the arc plate storage groove is composed of a right-angle groove and a storage groove, and a control rod is installed inside the right-angle groove.

[0015] Furthermore, the arc-shaped cover plate is installed counterclockwise inside the arc-shaped outer groove.

[0016] The technical effects and advantages of the present invention:

[0017] 1. By providing a precise light emitter, a reflective component, and a photosensitive arc plate, the present invention is conducive to making the light of the precise light emitter produce a lateral change on the photosensitive arc plate due to the vibration of the reflective component. Through the amplification of the reflection light path, high-precision detection of vibration is realized, which is conducive to the high-precision processing of the power take-off shaft hole, avoiding high processing errors, ensuring the coordination of the feeding force and the rotation speed at all times, and machining high-precision holes.

[0018] 2. By providing an amplifier and a touch ball rod, the present invention is conducive to amplifying the central difference of the touch ball rod by the two beams of light emitted by the amplifier, accurately judging whether the clamping position is the center, and at the same time realizing high-precision adjustment of the center position by the automatic rotation of the adjusting rod, which is convenient for the processing of the inner diameter.

Detailed implementation manners

[0027] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and a positioning device for processing power take-off parts involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0028] Refer to Figure 1 and Figures 4 - 5, the present invention provides a positioning device for the machining of power take-off parts, including a support outer ring 1. The support outer ring 1 includes a support main ring 101. Four clamping grooves 104 are opened at the bottom of the support main ring 101. Two groups of hexagonal positioning holes 102 are opened at the top of the support main ring 101. Each group includes 3 separate hexagonal positioning holes 102. A positioning component 2 is installed on one group of hexagonal positioning holes 102. A cooling component 3 is installed at the bottom of the positioning component 2. A reflective component 5 is installed on the side of the positioning component 2. A plurality of arc plate storage grooves 103 are opened at the top of the support main ring 101. The number of arc plate storage grooves 103 is the same as the number of precise light emitters 4. A photosensitive arc plate 6 is installed inside the arc plate storage groove 103. The photosensitive arc plate 6 is used to collect the light of the precise light emitter 4;

[0029] In this embodiment, it should be specifically noted that: the arc plate storage groove 103 is composed of a right-angle groove and a storage groove. A control rod is installed inside the right-angle groove. During use, the control rod of the right-angle groove pushes the photosensitive arc plate 6 to rise from the storage groove and be in the same plane as the precise light emitter 4.

[0030] The main difference between this embodiment and the prior art is that in this embodiment, the contact ball rod 16 is used to contact the workpiece, and the clamping error is transmitted to the transmission component 14 to make it rotate. Through the amplification of the amplifier 15, the precise detection of the central position is realized on the photosensitive straight plate 12. At the same time, the vibration during drilling is used to cause the position of the light of the precise light emitter 4 at the photosensitive arc plate 6 to change by the reflector 501, realizing the high-precision detection of the vibration during drilling. Specifically, it lies in the reflective component 5 and the amplifier 15;

[0031] The above structure is the main structure of this embodiment, which solves the problems that the center hole of the power take-off is prone to vibration and deviation during high-precision drilling at present, and at the same time solves the problem of too low center positioning accuracy. The precise light emitter 4 is a prior structure. The connection method between the precise light emitter 4 and the photosensitive arc plate 6 and the optical detection program are not specifically described in this embodiment.

[0032] Refer to Figure 2, the positioning component 2 includes a drilling ring 201. A plurality of placement grooves 202 are formed on the side surface of the drilling ring 201. A reflective component 5 is installed inside the placement groove 202. Arc-shaped outer grooves 204 are formed on both sides of the placement groove 202. An arc-shaped cover plate 7 is installed inside the arc-shaped outer groove 204. The arc-shaped cover plate 7 is used to cover and protect the reflective component 5 after use. Three radiation support plates 203 are fixedly connected to the side surface of the drilling ring 201. The bottom of the terminal of the radiation support plate 203 is fixedly connected to a positioning short rod 205. The positioning short rod 205 is installed inside the hexagonal positioning hole 102. Between the plurality of positioning short rods 205 are used to fix the processing points. A moving groove 206 is formed inside the drilling ring 201. The cooling component 3 is installed on the moving groove 206. During use, the height position of the inclined nozzle 303 is adjusted by sliding up and down in the moving groove 206.

[0033] In this embodiment, it should be specifically noted that: the aperture size of the drilling ring 201 has multiple models. During processing, the shaft hole is processed by selecting an appropriate aperture. Square grooves are formed on the radiation support plate 203. Scales are formed inside the square grooves. By replacing the positioning short rod 205 and the fixed position of the hexagonal positioning hole 102 and different positions inside the square groove of the radiation support plate 203, auxiliary holes can be opened on the outer side of the shaft hole, which is convenient for opening multiple circumferential holes on the same plane.

[0034] Refer to Figure 2 , the cooling component 3 includes a water tank 301. A positioning inner ring 304 is fixedly connected to the top of the water tank 301. The positioning inner ring 304 is installed inside the moving groove 206. A water storage cavity is formed inside the side surface of the water tank 301. The outer side of the water storage cavity is communicated with the connecting head 302. A plurality of inclined nozzles 303 are installed at the bottom of the water tank 301. The inclined nozzles 303 are installed obliquely. The inclination angles of the plurality of inclined nozzles 303 all face the edge of the hole processing position, which is beneficial to cooling the heat generated during the drilling process.

[0035] In this embodiment, it should be specifically noted that: the fixing method of the positioning inner ring 304 in the moving groove 206 belongs to the prior art, including but not limited to tightening with external threads, pin fixing, etc. The present application does not make specific limitations on the fixing method at this place. The connecting head 302 is connected to an external water pipe.

[0036] Refer to Figures 2 - 3, the reflective component 5 includes a reflector 501 and a shock-sensitive arc plate 502. The reflector 501 and the shock-sensitive arc plate 502 are connected by a buffer spring 503. The reflector 501 is installed on the placement groove 202, and the shock-sensitive arc plate 502 is installed on the inner diameter side of the drilling ring 201. When vibration occurs, the vibration is transmitted from the shock-sensitive arc plate 502 to the reflector 501 through the buffer spring 503, causing the reflector 501 to vibrate. At this time, the light emitted by the precise light emitter 4 is reflected by the reflector 501 onto the photosensitive arc plate 6. The light on the photosensitive arc plate 6 undergoes a lateral change, and the change amplitude is positively correlated with the vibration magnitude. By detecting the vibration frequency and amplitude of the light, the vibration condition is judged, and then the problems during drilling are judged, which is convenient for further adjusting the drilling process to ensure a high-precision drilling effect.

[0037] In this embodiment, it should be specifically noted that: the arc-shaped cover plate 7 is installed counterclockwise inside the arc-shaped outer groove 204. When drilling is required, rotate the arc-shaped cover plate 7 counterclockwise to expose the reflective component 5. The arc-shaped cover plate 7 is received inside the arc-shaped outer groove 204, making the reflector 501 in an inclined state under the action of the shock-sensitive arc plate 502. The light of the precise light emitter 4 is reflected on the reflector 501 and then onto the photosensitive arc plate 6. When drilling is completed, rotate the arc-shaped cover plate 7 in the reverse direction. The arc-shaped cover plate 7 extends out from the inside of the arc-shaped outer groove 204 to cover the reflector 501 to protect it. At this time, since the shock-sensitive arc plate 502 still applies an outward thrust to the reflector 501, the reflector 501 is in close contact with the inner wall of the arc-shaped cover plate 7, and the reflector 501 cannot move freely, playing a shock-absorbing role and facilitating the safety protection of the reflector 501 during transportation.

[0038] Refer to Figures 5 - 6 , the moving box 10 is installed on the side of the supporting main ring 101. The side of the moving box 10 is sleeved with an adjusting rod 8. On both sides of the moving box 10 on the adjusting rod 8, a transverse push plate 9 and a first spring 11 are respectively installed. The transverse push plate 9 is threadedly connected to the adjusting rod 8, and the first spring 11 is sleeved on the adjusting rod 8. When the adjusting rod 8 rotates, the adjusting rod 8 drives the transverse push plate 9 to push the moving box 10 towards the center. When the adjusting rod 8 rotates in the reverse direction, the first spring 11 pushes the moving box 10 to move in the reverse direction. A photosensitive straight plate 12 is installed on the side of the moving box 10, and a transmission component 14 is installed inside the moving box 10. The side of the transmission component 14 is meshed with an amplifier 15. A clamping contact plate 13 is installed at the bottom of the side of the moving box 10. The clamping contact plate 13 is installed on the side of the moving box 10 through a spring. Two deep holes are opened on the side of the clamping contact plate 13, and a point contact ball rod 16 is installed inside the deep holes. One end of the point contact ball rod 16 is installed on the rotating sub-plate 1402. When the clamping position is not at the center, the housing exerts different forces on the point contact ball rod 16, and this force causes the transmission component 14 to rotate a certain angle.

[0039] In this embodiment, it should be specifically noted that: the rotation of the adjusting rod 8 is controlled by the central control unit. An information collection unit and a central control unit are installed inside the support outer ring 1. The information collection unit collects the light information of the photosensitive straight plate 12, calculates the central position difference through the light deviation of the two light emitters 1502, and the central control unit controls the rotation angles of the two side adjusting rods 8. Through multiple feedbacks, high-precision positioning of the center is achieved, and the following effects are realized: after placing the device outside the processing point and starting the device, the device automatically completes center calibration through the above content and can directly perform drilling, with simple operation and high precision.

[0040] Referring to Figure 7 , the transmission component 14 includes a transmission rod 1401. A rotating sub-plate 1402 is fixedly connected to the side of the transmission rod 1401, and a transmission gear 1403 is fixedly connected to the top of the transmission rod 1401. The amplifier 15 includes an amplification gear 1501. A double light emitter 1502 is installed at the bottom of the amplification gear 1501. The double light emitter 1502 is composed of two V-shaped distributed light sources. The light rays emitted by the two light sources form an asymmetric light spot on the photosensitive straight plate 12, and the deviation size of the clamping position is obtained by calculating the difference of the light spot center points.

[0041] In this embodiment, it should be specifically noted that: the tooth number ratio of the transmission gear 1403 to the amplification gear 1501 affects the amplification ratio of the difference of the point-touch ball rod 16, which belongs to the prior art, and the tooth number ratio is not specifically limited herein in this application.

[0042] The working principle of the present invention:

[0043] The main problem solved by this embodiment is: through the contact between the point-touch ball rod 16 and the component, the center error is transmitted to the transmission component 14 to make it rotate, and through the amplification of the amplifier 15, the precise detection of the center position is realized on the photosensitive straight plate 12. At the same time, the vibration during drilling makes the position of the light ray of the precise light emitter 4 on the photosensitive arc plate 6 change due to the reflector 501, realizing the high-precision detection of the vibration during drilling, solving the problem that the center hole of the power take-off is prone to vibration and deviation during high-precision drilling, and at the same time solving the problem of too low center positioning accuracy.

[0044] The specific steps are as follows:

[0045] Put the support outer ring 1 on the outside of the hole in the processing shell. Rotate the adjusting rod 8. Since the transverse push plate 9 is installed on the adjusting rod 8, the rotation of the adjusting rod 8 drives the transverse push plate 9 to move sideways, pushing the moving box 10 and the clamping contact plate 13 to clamp the outer diameter of the hole. As the clamping contact plate 13 continuously applies pressure to the surface of the shell, the clamping contact plate 13 contracts into the interior of the moving box 10, and the touch ball rod 16 extends from the interior of the clamping contact plate 13 to contact the surface of the shell. At this time, if the clamping position is not the central position, the shell pushes the two touch ball rods 16 to move. The difference in the moving distances causes the transmission assembly 14 to rotate, and the rotation drives the magnifying gear 1501 and the double-headed light emitter 1502 to rotate. At this time, the double-headed light emitter 1502 irradiates two beams of light on the clamping contact plate 13, and the difference between the two beams of light on the clamping contact plate 13 realizes the amplification of the difference of the touch ball rod 16 to accurately judge whether the clamping position is the center, and then high-precision adjustment of the center position is realized by rotating the adjusting rods 8 on both sides again;

[0046] After completing the high-precision clamping and fixing of the center position, select a positioning component 2 with a suitable aperture and install it. Install the positioning short rod 205 inside the hexagonal positioning hole 102. Pull down the cooling component 3. The positioning inner ring 304 slides inside the moving groove 206 so that the inclined nozzle 303 is near the top of the processing pore. The drilling bit is placed inside the drilling ring 201 to work, and the drill bit contacts the shock-sensing arc plate 502. When starting the processing, external coolant enters the interior of the water tank 301 and is sprayed on the processing hole through the inclined nozzle 303 for cooling;

[0047] When the drill bit vibrates, the vibration effect is transmitted to the shock-sensing arc plate 502. The shock-sensing arc plate 502 drives the reflector 501 to vibrate through the buffer spring 503. Since the light emitted by the precise light emitter 4 at this time is reflected by the reflector 501 onto the photosensitive arc plate 6, when the reflector 501 vibrates, the light undergoes a lateral change on the photosensitive arc plate 6, and the high-precision detection of the vibration is realized through the amplification of the reflection light path, which is beneficial to controlling the high-precision processing of the power take-off shaft hole and avoiding higher processing errors.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
