Description

Technical Field

[0001] This utility model relates to the field of bevel gear shaft processing technology, and in particular to a hollow bevel gear shaft clamping device. Background Technology

[0002] When a gear machining machine is in operation, the gear teeth must undergo further finishing after rough machining, such as gear grinding. This requires adjusting the angle of the gear in the circumferential direction to set the grinding wheel, and then fastening it to a special fixture on the worktable to ensure that both sides of the gear teeth can be finished by gear grinding.

[0003] Currently, when machining the inner bore of parts on a horizontal lathe, the parts need to be clamped and aligned on the lathe. For hollow bevel gear shafts, the lathe clamps the tapered outer diameter in line contact, meaning the clamping device and the part are in line contact. This results in unreliable clamping, leading to low alignment accuracy and affecting the precision of the machined gears. Therefore, an improved hollow bevel gear shaft clamping device is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a hollow bevel gear shaft clamping device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a hollow bevel gear shaft clamping device, including a clamping frame. The clamping frame has a primary groove and a secondary groove. A plurality of support plates are rotatably connected to the secondary groove, and a telescopic cylinder is provided between the support plates and the inner wall of the secondary groove. A drive shaft is rotatably connected to the primary groove, and a horizontal guide rod is fixedly connected to one side of the drive shaft within the primary groove. A stop plate is threaded onto the drive shaft and sleeved onto the horizontal guide rod. A sleeve frame is fixedly connected to the rear end of the clamping frame, and a bidirectional lead screw is rotatably connected to the sleeve frame. Two clamping plates are threaded onto the bidirectional lead screw, and clamping pads are fixedly connected to the clamping plates.

[0007] Preferably, in any of the above solutions, the clamping frame adopts a rectangular structure, and both the primary slot and the secondary slot adopt a rectangular structure.

[0008] The above technical solution employs the following: A clamping frame provides clamping space for the hollow bevel gear shaft. A primary slot is formed within the clamping frame to provide installation space for the drive shaft, horizontal guide rod, and backing plate. A secondary slot is formed within the clamping frame, providing installation and movement space for the backing plate and telescopic cylinder. The clamping frame adopts a rectangular structure, and the primary and secondary slots also correspondingly adopt rectangular structures to facilitate the installation of the components within the primary and secondary slots.

[0009] Preferably, in any of the above schemes, a plurality of mounting plates are fixedly connected in the secondary groove, and the support plate is rotatably connected to the mounting plates via a rotating shaft.

[0010] The above technical solution employs a backing plate to abut against the conical surface of the hollow bevel gear shaft. The backing plate is rotatably connected within the secondary groove, allowing its tilt angle to be adjusted according to the specific shape of the hollow bevel gear to be processed, thus ensuring stable contact between the backing plate and the conical surface of the hollow bevel gear.

[0011] Preferably, of any of the above solutions, there are four backrests, the backrests are of an isosceles trapezoidal structure, and the telescopic cylinder is rotatably connected to the center line of the backrest.

[0012] The above technical solution employs four abutment plates that abut against the conical surface of the hollow bevel gear shaft from different directions, increasing the contact area between the clamping device and the hollow bevel gear shaft and ensuring its stability. The abutment plates adopt an isosceles trapezoidal structure to accommodate its rotation and prevent different abutment plates from colliding after rotation. A telescopic cylinder provides support for the abutment plates, connected at the center line of the abutment plates to facilitate providing balanced and stable support.

[0013] Preferably, in any of the above embodiments, there are several drive shafts, and handwheels are fixedly connected to the ends of both the drive shafts and the bidirectional lead screw.

[0014] The above technical solution employs a drive shaft to move the abutment plate horizontally. Rotating the drive shaft, under the constraint of the horizontal guide rod, causes the abutment plate to be pushed horizontally by the thread. After movement, the abutment plate can abut against the back of the hollow bevel gear shaft, cooperating with the backing plate to clamp the hollow bevel gear shaft. The arrangement of several drive shafts provides the conditions for the arrangement of several sets of abutment plates. It should be noted that due to the arrangement of the abutment plate, the hollow bevel gear shaft can be inserted at an angle when clamping it, preventing the abutment plate from jamming the hollow bevel gear shaft.

[0015] Preferably, in any of the above embodiments, connecting plates are fixedly connected to both sides of the sleeve frame, the bidirectional screw is rotatably connected to the connecting plate on one side, and a constraint rod is fixedly connected to the connecting plate on the other side. The clamping plate passes through the sleeve frame and is threadedly connected to the bidirectional screw at one end and sleeved on the constraint rod at the other end.

[0016] The above technical solution employs the following: The sleeve provides insertion space for the hollow bevel gear shaft. Rotating the double-acting lead screw causes its threads to push the two clamping plates to move towards or away from each other. Connecting plates are installed on both sides of the sleeve, and the double-acting lead screw is positioned on these connecting plates, placing it outside the sleeve to prevent it from interfering with the installation of the hollow bevel gear shaft. A constraint rod is installed on one side of the sleeve, which constrains the clamping plates to prevent them from rotating with the double-acting lead screw.

[0017] Preferably, in any of the above schemes, the two clamping plates are symmetrically arranged on the bidirectional lead screw, and the clamping pad adopts an arc-shaped structure.

[0018] The above technical solution employs a clamping plate to hold the hollow bevel gear shaft. A clamping pad is provided on the clamping plate; this pad can deform to a certain extent after the hollow bevel gear shaft is clamped, thus creating a buffer between the clamping plate and the hollow bevel gear shaft.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] 1. This hollow bevel gear shaft clamping device comprises a clamping frame, a backing plate, a telescopic cylinder, a drive shaft, a stop plate, a sleeve frame, a double-acting screw, clamping plates, and clamping pads. In use, the hollow bevel gear shaft is inserted into the clamping frame. Based on the angle of the conical surface of the hollow bevel gear shaft, the angle of the backing plate is adjusted using the telescopic cylinder, causing it to abut against the conical surface of the hollow bevel gear shaft. Rotating the drive shaft, under the constraint of the horizontal guide rod, pushes the stop plate horizontally. After moving, the stop plate abuts against the back of the hollow bevel gear shaft, clamping it in conjunction with the backing plate. Rotating the double-acting screw, its threads push the two clamping plates to move towards each other, and the clamping plates, in conjunction with the clamping pads, clamp and fix the hollow bevel gear shaft. This multi-directional and comprehensive clamping and fixing of the hollow bevel gear shaft makes it more stable and helps improve machining accuracy.

[0021] 2. This hollow bevel gear shaft clamping device features a rectangular clamping frame, with corresponding rectangular structures for the primary and secondary slots, facilitating the installation of components within each slot. Connecting plates are installed on both sides of the frame, with the double-acting lead screw positioned on these plates outside the frame to prevent it from interfering with the installation of the hollow bevel gear shaft. A constraint rod is installed on one side of the frame to restrain the clamping plate and prevent it from rotating with the double-acting lead screw.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1-4 As shown, this utility model includes a clamping frame 1, which has a primary groove 2 and a secondary groove 3. Several backing plates 4 are rotatably connected in the secondary groove 3, and a telescopic cylinder 5 is provided between the backing plates 4 and the inner wall of the secondary groove 3. A drive shaft 6 is rotatably connected in the primary groove 2, and a horizontal guide rod 7 is fixedly connected in the primary groove 2 on one side of the drive shaft 6. A stop plate 8 is threadedly connected to the drive shaft 6 and is sleeved on the horizontal guide rod 7. A sleeve frame 9 is fixedly connected to the rear end of the clamping frame 1. A bidirectional lead screw 10 is rotatably connected to the sleeve frame 9. Two clamping plates 11 are threadedly connected to the bidirectional lead screw 10, and clamping pads 12 are fixedly connected to the clamping plates 11.

[0032] Example 1: The clamping frame 1 adopts a rectangular structure, and both the primary slot 2 and the secondary slot 3 adopt rectangular structures. The clamping frame 1 provides clamping space for the hollow bevel gear shaft 13. A primary slot 2 is provided within the clamping frame 1 to provide installation space for the drive shaft 6, horizontal guide rod 7, and abutment plate 8. A secondary slot 3 is provided within the clamping frame 1 to provide installation and movement space for the support plate 4 and telescopic cylinder 5. The rectangular structure of the clamping frame 1, and the corresponding rectangular structures of the primary and secondary slots 2 and 3, facilitate the installation of the components within the primary and secondary slots 2 and 3. Several mounting plates are fixedly connected within the secondary slot 3, and the support plate 4 is rotatably connected to the mounting plates via a rotating shaft. The support plate 4 is used to abut against the conical surface of the hollow bevel gear shaft 13. The support plate 4 is rotatably connected within the secondary slot 3, allowing its tilt angle to be adjusted according to the specific shape of the hollow bevel gear 13 to be processed, ensuring that the support plate 4 stably conforms to the conical surface of the hollow bevel gear 13.

[0033] Example 2: There are four support plates 4, each with an isosceles trapezoidal structure. A telescopic cylinder 5 is rotatably connected to the centerline of the support plates 4. The four support plates 4 abut against the conical surface of the hollow bevel gear shaft 13 from different directions, increasing the contact area between the clamping device and the hollow bevel gear shaft 13, ensuring its stability. The isosceles trapezoidal structure of the support plates 4 is adapted to its rotation, preventing different support plates 4 from colliding after rotation. The telescopic cylinder 5 provides support for the support plates 4, and its connection to the centerline of the support plates 4 facilitates providing balanced and stable support. There are several drive shafts 6, and handwheels are fixedly connected to the ends of both the drive shafts 6 and the bidirectional lead screw 10. The drive shafts 6 are used to drive the support plates 8 to move horizontally. Rotating the drive shafts 6, under the constraint of the horizontal guide rod 7, the support plates 8 are pushed horizontally by the thread. After moving, the support plates 8 can abut against the back of the hollow bevel gear shaft 13, cooperating with the support plates 4 to clamp the hollow bevel gear shaft 13. The arrangement of several drive shafts 6 provides the conditions for the arrangement of several sets of abutment plates 8. It should be noted that, due to the arrangement of the abutment plates 8, the hollow bevel gear shaft 13 can be inserted in an inclined state when clamping it, so as to avoid the abutment plates 8 jamming the hollow bevel gear shaft 13.

[0034] Example 3: Connecting plates are fixedly connected to both sides of the sleeve frame 9. A bidirectional lead screw 10 is rotatably connected to one connecting plate, and a constraint rod is fixedly connected to the other connecting plate. A clamping plate 11 passes through the sleeve frame 9, with one end threadedly connected to the bidirectional lead screw 10 and the other end sleeved on the constraint rod. The sleeve frame 9 provides insertion space for the shaft of the hollow bevel gear 13.

Connecting plates are provided on both sides of the sleeve frame 9, and the bidirectional lead screw 10 is placed on the connecting plates, placing it on the outside of the sleeve frame 9 to avoid affecting the installation of the hollow bevel gear 13. A constraint rod is provided on one side of the sleeve frame 9 to constrain the clamping plate 11 and prevent it from rotating with the bidirectional lead screw 10. The two clamping plates 11 are symmetrically arranged on the bidirectional lead screw 10, and the clamping pad 12 adopts an arc-shaped structure. The clamping plates 11 are used to clamp the hollow bevel gear 13. A clamping pad 12 is provided on the clamping plate 11. The clamping pad 12 can deform to a certain extent after clamping the hollow bevel gear shaft 13, forming a buffer between the clamping plate 11 and the hollow bevel gear shaft 13.

[0035] The working principle of this utility model is as follows:

[0036] S1. Insert the hollow bevel gear shaft 13 into the clamping frame 1. According to the inclination angle of the conical surface of the hollow bevel gear shaft 13, use the telescopic cylinder 5 to adjust the angle of the backing plate 4 so that it abuts against the conical surface of the hollow bevel gear shaft 13.

[0037] S2. Rotating the drive shaft 6, under the constraint of the horizontal guide rod 7, the abutment 8 is pushed horizontally by the thread. After moving, the abutment 8 can abut against the back of the hollow bevel gear shaft 13, and cooperate with the backing plate 4 to clamp the hollow bevel gear shaft 13;

[0038] S3. Rotate the bidirectional lead screw 10, and the thread on it pushes the two clamping plates 11 to move towards each other. The clamping plates 11, together with the clamping pad 12, clamp and fix the shaft of the hollow bevel gear shaft 13.
