Description

Technical Field

[0001] The utility model belongs to the technical field of gear processing equipment, in particular to a gear end surface processing positioning tool. Background Art

[0002] During the gear processing, both end faces of the gear need to be polished or cut to meet the requirements of production regulations. In order to facilitate the processing of the gear, a positioning tool is needed to position the gear. The existing positioning tool usually includes a workbench and a clamping assembly. The principle is: first place the gear to be processed on the workbench, and then use the two clamping assemblies on the top of the workbench to clamp the gear from both sides of the gear. Although this type of positioning tool can achieve the positioning of the gear.

[0003] However, when one end face of the gear is machined and the other end face of the gear needs to be machined, the flipping process usually includes three steps, namely, the gear needs to be removed from the two clamping components first, then the gear is flipped, and finally the gear is clamped using the two clamping components. This wastes a lot of time and reduces the efficiency of gear machining. Especially when machining large gears, due to the heavy weight of the gears, it is more laborious to manually load and unload and flip them, and the gears are easily dropped and the tooth tips are damaged due to improper operation.

[0004] A Chinese patent with authorization announcement number CN219541923U discloses a gear end face processing and positioning tool, including a base, a screw and two mounting plates, one of which is slidably connected to the top of the base, and the other mounting plate is fixed to the top of the base, the screw horizontally passes through the mounting plate slidably connected to the base, and the screw is threadedly connected to the mounting plate, a driving assembly for driving the screw to rotate is provided on the top of the base, and a rotating shaft is rotatably provided on opposite sides of the two mounting plates, and a clamping assembly for clamping the gear to be processed is fixedly provided on opposite ends of the two rotating shafts, one of the rotating shafts passes through the mounting plate and extends in a direction away from the other rotating shaft, and locking rods are provided on both sides of the rotating shaft passing through one end of the mounting plate, and the angle between the two locking rods is 180°, and a locking assembly for locking the locking rod is also provided on the side wall of the mounting plate, so as to solve the problem that the existing gear positioning device in the prior art is not convenient for flipping the gear.

[0005] However, the above has the following shortcomings:

[0006] When the above patent clamps the gear, the side of the gear is clamped, and the bottom side of the gear is unsupported. When the end face of the gear is processed, the gear is subjected to axial pressure, which can easily cause it to slip downward, thereby affecting the processing accuracy of the end face.

[0007] When machining the gear end face, since the verticality requirement between the gear end face and the gear axis is high, and the above patent does not have a positioning device for the gear axis, it is easy to affect the verticality between the machined end face and the gear axis. Utility Model Content

[0008] In order to overcome the deficiencies of the prior art, the utility model solves the technical problem of utilizing the movement of the support plate to drive the flip ring to flip, so that the gear can be automatically flipped without disassembling the gear, and the gear end face on the other side can be processed, which greatly saves time and manpower and improves processing efficiency. The flipping process is more stable and controllable, and the gear can be effectively prevented from being damaged during the flipping process. No matter which side of the gear end face is processed, the support plate can be used to support the bottom of the gear, thereby improving the stability of clamping and effectively improving the processing accuracy. The locating pin is used to stably and accurately position the axis of the gear during clamping and end face processing, ensuring the verticality between the rear end face and the gear axis after processing, thereby further improving the processing accuracy of the gear and improving the quality of the finished product.

[0011] No matter which side of the gear end face is processed, the support plate can be used to support the bottom of the gear, thereby improving the clamping stability and effectively improving the processing accuracy.

[0015] The support plate and the flip ring are driven by a lead screw, the driving effect is stable, the movement of the support plate and the flip ring is smooth and reliable, and the moving direction and speed of the flip ring and the support plate can be accurately controlled.

[0016] Furthermore, a positioning pin is threadedly connected at the center of the upper side of the lifting block, a third support is fixedly connected to the lower side of the support plate at a corresponding position of the lifting block, a first electric cylinder is fixedly connected to the bottom of the third support, and an extended end of the first electric cylinder passes through the third support and is fixedly connected to the bottom side of the lifting block.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a gear end surface processing and positioning tooling comprises a bracket 10, a flip ring 11 is rotatably connected between the top ends of two mutually symmetrical brackets 10, a support plate 16 is slidably connected to the two brackets 10, a lifting block 27 is slidably connected at the center of the support plate 16, two slide grooves 19 are opened on the support plate 16 at both sides of the lifting block 27, a slider 18 is slidably connected in each of the slide grooves 19, a connecting block 17 is rotatably connected between the two ends of the two sliders 18 extending out of the slide grooves 19, the connecting block 17 is fixedly connected to one side of the flip ring 11, and a locking component is provided on the bottom side of the support plate 16 near the two brackets 10.

[0033] By utilizing the movement of the support plate 16 and driving the flip ring 11 to flip, the gear can be automatically flipped without disassembling the gear, and the gear end face on the other side can be processed, which greatly saves time and manpower, improves processing efficiency, and makes the flipping process more stable and controllable, effectively preventing the gear from being damaged during the flipping process.

[0034] No matter which side of the gear end face is processed, the support plate 16 can be used to support the bottom of the gear, thereby improving the clamping stability and effectively improving the processing accuracy.

[0035] like Figure 1 , Figure 4 and Figure 6 As shown, a plurality of screw rods 12 are evenly distributed on the side wall of the flip ring 11 and are connected in meshing transmission. The end of each screw rod 12 away from the center of the flip ring 11 is fixedly connected to a hand wheel 13, and the end of each screw rod 12 close to the center of the flip ring 11 is rotatably connected to a rotating block 15. Each rotating block 15 is fixedly connected to a clamping block 14, and the lower surface of the clamping block 14 is in contact with the upper surface of the support plate 16.

[0036] A plurality of clamping blocks 14 are utilized to mesh with the tooth surface of the gear and clamp the gear, thereby stably clamping and fixing the gear, and the operation is simple and the clamping and fixing effect is stable.

[0037] like Figure 1 , Figure 3 and Figure 5 As shown, the two ends of the support plate 16 are fixedly connected with a first support 21 at the corresponding positions of the two slide grooves 19, and two first screws 20 respectively located in the two slide grooves 19 are rotatably connected between the two first supports 21, each of the first screws 20 is meshingly connected to the corresponding slider 18 for transmission, and one end of each first screw 20 is transmission-connected to a first motor 22, and second supports 25 are fixedly connected to both sides of the top of each of the brackets 10, and a second screw 23 is rotationally connected between each of the second supports 25 and the bottom of the bracket 10, and each of the second screws 23 is meshingly connected to the support plate 16 for transmission, and one end of each of the second screws 23 is transmission-connected to a second motor 24.

[0038] The support plate 16 and the flip ring 11 are driven by a lead screw, and the driving effect is stable. The movement of the support plate 16 and the flip ring 11 is smooth and reliable, and the movement direction and speed of the flip ring 11 and the support plate 16 can be accurately controlled.

[0039] like Figure 3 and Figure 5 As shown, a positioning pin 26 is threadedly connected at the center of the upper side of the lifting block 27, and a third support 28 is fixedly connected to the lower side of the support plate 16 at a corresponding position of the lifting block 27. A first electric cylinder 29 is fixedly connected to the bottom of the third support 28, and an extended end of the first electric cylinder 29 passes through the third support 28 and is fixedly connected to the bottom side of the lifting block 27.

[0040] In the process of clamping the gear and processing the gear end face, the locating pin 26 is used to position the axis of the gear, thereby improving the positioning accuracy between the processing equipment and the gear, and effectively ensuring the verticality between the gear end face and the gear axis after processing, thereby improving the processing accuracy and processing effect.

[0041] like Figure 3 and Figure 5 As shown, two fourth supports 30 are fixedly connected to the lower side of the support plate 16 near the positions of the two brackets 10, and a second electric cylinder 31 is fixedly connected to each of the fourth supports 30. A locking hole 32 is opened on each of the brackets 10 at the position corresponding to the second electric cylinder 31, and the extended end of each of the second electric cylinders 31 is inserted into the corresponding locking hole 32.

[0042] During the processing of the gear end face, the second electric cylinder 31 is used to lock the position of the support plate 16, so that the support effect of the support plate 16 on the gear is further improved, and the stability of the entire clamping device during the processing is improved to ensure the processing effect of the gear end face.

[0043] In this embodiment, initially, the operator installs the present invention at the corresponding position of the end face processing equipment, and connects the power supply and the control system. The flip ring 11 remains horizontal and the support plate 16 is close to the lower side of the flip ring 11. At this time, the extended end of the second electric cylinder 31 is inserted into the locking hole 32 to maintain a locked state. The tooth shape of the clamping block 14 accurately corresponds to the gear to be processed, and the diameter of the positioning pin 26 accurately corresponds to the axial hole of the gear to be processed.

[0044] Subsequently, the gear to be end-face processed is placed on the inner side of the flip ring 11 and supported by the support plate 16, and the axial hole of the gear is ensured to be accurately fitted on the positioning pin 26. The operator then turns the hand wheel 13 in turn, thereby moving each clamping block 14 toward the center to clamp the gear. During the clamping process, since the axial hole of the gear is passed through by the positioning pin 26, the gear will not be offset when multiple clamping blocks 14 clamp the gear in turn, thereby greatly improving the positioning accuracy between the gear and the processing equipment.

[0045] After the gear is fixed by an unfixed clamp, the end face of the gear is processed by processing equipment. During the processing, the support plate 16 stably supports the gear to prevent the gear from sliding downward, thereby improving the processing accuracy of the gear end face after processing. The positioning pin 26 is used to position the axis of the gear, effectively preventing the gear from tilting and causing poor verticality between the gear end face and the gear axis after processing.

[0046] When the gear needs to be flipped over to process the other side after the processing is completed, the control system first controls the second electric cylinder 31 to retract, so that the extended end of the second electric cylinder 31 disengages from the locking hole 32 and contacts the locking state, and at the same time drives the first electric cylinder 29 to retract, so that the lifting block 27 descends with the positioning pin 26 and thus disengages the positioning pin 26 from the gear shaft hole, and then the control system drives the second lead screw 23 to rotate through the second motor 24, thereby driving the support plate 16 to move downward smoothly, and during the downward movement of the support plate 16, the fourth support 30 and the second electric cylinder 31 move downward together, and while the support plate 16 moves downward, the control system drives the first lead screw 20 to rotate through the first motor 22, thereby driving the two sliders 18 to move in the slide groove 19, and the two actions of the downward movement of the support plate 16 and the movement of the slider 18 are superimposed to drive the flip ring 11 to flip.

[0047] When the flipping angle of the flip ring 11 reaches 90°, the control system makes the second lead screw 23 rotate in the opposite direction, so that the support plate 16 rises again, and the first lead screw 20 continues to drive the slider 18 to move in the original direction, so that the flip ring 11 continues to flip in one direction. Finally, the flip ring 11 is horizontal again, and the support plate 16 is close to the bottom side of the flip ring 11 again, then the control system stops the first motor 22 and the second lead screw 23. At this time, the gear has been flipped 180°. Then the control system controls the second electric cylinder 31 and the first electric cylinder 29 to extend outward again, and the output end of the second electric cylinder 31 is inserted into the locking hole 32 again for locking, and the first electric cylinder 29 pushes the lifting block 27 and the positioning pin 26 to rise, so that the positioning pin 26 is inserted into the shaft hole of the gear again, and then the gear end face is processed using processing equipment. Embodiment 2:

[0048] like Figure 5 and Figure 6As shown, as a further embodiment, when it is necessary to process gears with different modules, different diameters and different apertures, stable clamping of different gears can be achieved by replacing the clamping block 14 with the corresponding module and arc, and by unscrewing and removing the positioning pin 26 from the lifting block 27 and replacing the positioning pin 26 with a different diameter, gears with different apertures can be accurately and stably positioned, thereby greatly improving the scope of application of the device and reducing the cost of use.
