Description

Technical Field

[0001] This utility model belongs to the field of gear precision machining technology, and relates to gear shaving, specifically to a gear shaving bracket. Background Technology

[0002] Gear shaving is a finishing process for soft-tooth gears. Gear shaving primarily involves the meshing of gears with shaving cutters and high-speed operation for finishing. In existing CNC gear shaving machines, the clamping method for parts during shaving is mainly through a shaving mandrel and the machine tool's own double centers. During loading and unloading, the operator pushes the part on the shaving mandrel to the appropriate position using the machine's support, the machine's double centers clamp the shaving mandrel, and then the shaving process is performed.

[0003] In existing gear shaving machines, the shaving support typically uses two horizontal and parallel guide rails. After the operator loads the part onto the shaving mandrel, they must place the mandrel on the shaving support and then push it to the two centers, ensuring the mandrel hole is aligned with the centers. After manually closing the door, the centers automatically tighten the mandrel before shaving can begin. Because a horizontal support is used, the operator needs to push the mandrel to the designated position each time. However, due to unpredictable factors, the mandrel hole and the center axis may not be aligned after being pushed in due to gravity or inertia. This can lead to the machine centers not tightening the support or dislocating the support, preventing the machine from processing the part or resulting in defective products. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shaving bracket to solve the technical problem that the positional accuracy between the shaving spindle on the shaving bracket and the double centers of the machine tool needs to be further improved when the shaving bracket is used for shaving processing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A shaving bracket includes an L-shaped guide rail, wherein the L-shaped guide rail includes a transverse guide rail and a vertical spindle limiting guide rail integrally provided at the other end of the transverse guide rail.

[0007] The inner corner at the connection between the horizontal guide rail and the vertical mandrel limiting guide rail is an arc-shaped corner, and the radius of curvature of the arc-shaped corner is equal to the radius of curvature of the outer surface of the shaving mandrel.

[0008] This utility model also has the following technical features:

[0009] Specifically, the transverse guide rail has a first longitudinally penetrating fixing screw hole near one end, which is used to connect with the gear shaving machine.

[0010] The transverse guide rail is provided with a second longitudinally penetrating fixing screw hole near the other end. The transverse guide rail is installed on the upper part of the adjusting bracket through the second fixing screw hole. The lower part of the adjusting bracket is installed on the upper part of the vertical support base, and the lower part of the vertical support base is used to install on the gear shaving machine.

[0011] Preferably, the vertical height of the central axis of the first fixing screw hole is lower than the vertical height of the central axis of the second fixing screw hole.

[0012] Specifically, a first fixing screw is provided in the first fixing screw hole, and the transverse guide rail is connected to the gear shaving machine through the first fixing screw.

[0013] Specifically, a second fixing screw is provided in the second fixing screw hole, and the transverse guide rail is connected to the upper part of the adjusting bracket through the second fixing screw.

[0014] Preferably, the adjusting bracket includes an angle steel bracket, and the vertical plate of the angle steel bracket is provided with a longitudinally penetrating transverse strip hole. The second fixing screw passes through the transverse strip hole and can move laterally within the transverse strip hole.

[0015] Specifically, the bottom front end of the horizontal plate of the angle steel bracket is also integrated with a vertical adjustment bracket. The vertical adjustment bracket is also provided with a vertically penetrating vertical strip hole. A third fixing screw is provided in the vertical strip hole, and the third fixing screw can move vertically in the vertical strip hole. The vertical adjustment bracket is connected to the upper part of the vertical support base through the third fixing screw.

[0016] Specifically, the vertical support base is arranged parallel to the rear side of the vertical adjustment bracket, and a third fixing screw hole is also provided in the upper part of the vertical support base, and the third fixing screw is installed in the third fixing screw hole.

[0017] Specifically, a longitudinally penetrating pin hole is provided at the lower part of the vertical support base, and the vertical support base is connected to the gear shaving machine through a positioning pin installed in the pin hole.

[0018] Preferably, the lower part of the vertical support base is provided with a locking screw hole, which is arranged horizontally and a locking screw is provided in the locking screw hole. The locking screw can longitudinally limit the positioning pin of the gear shaving machine.

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

[0020] (I) The L-shaped guide rail in this utility model device limits the lateral movement of the shaving spindle, avoiding the problem of the workpiece being misaligned due to the central axis of the machine tool's double center being not on the same straight line as the central axis of the shaving spindle hole, thus reducing the probability of producing defective products during production.

[0021] (II) This utility model proposes an inclined gravity self-centering shaving bracket. The shaving bracket is improved by optimizing the horizontal guide rail into an L-shaped guide rail, which has a slope after installation. The operator only needs to place the shaving mandrel on the shaving bracket, and the shaving mandrel will automatically slide to the designated position without much manual intervention, simplifying the loading and unloading process. When processing heavy large parts, the parts can slide to the designated position by their own weight, saving time and effort and reducing the labor intensity of the operator.

[0022] (III) The L-shaped guide rail in this utility model relies on the fact that the vertical height of the center axis of the first fixed screw hole and the vertical height of the center axis of the second fixed screw hole are 5mm apart, so that the shaving spindle with the part to be processed can slide freely along the transverse guide rail under its own gravity at a stable speed, without being too fast or too slow.

[0023] (IV) The inner corner of the connection between the other end of the horizontal guide rail and the vertical mandrel limiting guide rail in this utility model device is an arc-shaped corner, which makes the positioning of the shaving mandrel more stable and accurate than a right-angle corner.

[0024] (V) The device in this utility model has a simple structure, is easy to install, disassemble and adjust in height, saves a lot of time and improves processing efficiency; at the same time, the shaving bracket has a simple structure and lower manufacturing cost, and has certain economic value.
