Description

Technical Field

[0001] This utility model relates to the field of splined shaft stamping, specifically a splined shaft stamping device. Background Technology

[0002] Splined shafts are key components widely used in mechanical transmission. They transmit torque by meshing external splines on the shaft with internal splines in the hub bore. During the manufacturing process of splined shafts, stamping is often required for processing.

[0003] When existing stamping equipment is used for processing splined shafts, the cutting tool at the bottom of the stamping station may stick to the splined shaft or lift it up due to friction during its upward return stroke after completing the stamping action. This causes the splined shaft to detach from the processing station, which not only interrupts the automated production process and requires manual intervention to reset, but may also cause the lifted splined shaft to fall, resulting in surface damage to the product, or even causing equipment jamming or safety accidents, seriously affecting production efficiency and product yield.

[0004] Therefore, a spline shaft stamping device is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A splined shaft stamping device, such as Figures 1-4 As shown, the system includes a base 1, with a support rod 2 fixed to the upper end of the base 1 by bolts or welding. The support rod 2 supports a top seat 3. A machining seat 11 for mounting the splined shaft 12 to be tested is fixed to the middle of the base 1. A top seat 3 is fixed to the upper end of the support rod 2. A hydraulic cylinder 4 (model CDM1B50T100 / 70Z) is fixed to the upper end of the top seat 3. A lifting seat 5 is slidably mounted on the support rod 2, and the lifting seat 5 is mounted on the support rod 2 via a sliding sleeve. The output end of the hydraulic cylinder 4... The upper end of the lifting seat 5 is fixedly connected to the hydraulic cylinder 4. The output rod of the hydraulic cylinder 4 drives the lifting seat 5 to rise and fall. The lower end of the lifting seat 5 is fixedly connected to a stamping seat 8 for stamping the spline shaft 12 to be tested. The lower end of the stamping seat 8 is provided with a stamping tool. The output end of the hydraulic cylinder 4 drives the lifting seat 5 to rise and fall, so that the stamping seat 8 at the bottom stamps the spline shaft 12 to be tested. A fixed seat 14 is fixedly connected to one side of the base 1. A slide rod 15 is slidably installed at one end of the fixed seat 14. The slide rod 15 is used to limit the upper end of the spline shaft 12 to be tested.

[0024] The slide bar 15 is designed to slide horizontally. Before stamping, the slide bar 15 extends out of the fixed seat 14 and slides directly above the spline shaft. There is a small space between the slide bar 15 and the upper surface of the spline shaft 12 to be tested. The slide bar 15 will not push the spline shaft to make displacement. The tool at the bottom of the stamping seat 8 passes through the internal space of the slide bar 15 to stamp the spline shaft. When the stamping is completed and the stamping seat 8 returns, even if the stamping tool carries the spline shaft slightly up, it will be immediately blocked by the slide bar 15 above, forcing the spline shaft to separate from the tool and fall back to the processing seat 11. This solves the problem of the spline shaft being carried up and realizes continuous automated operation of production.

[0025] A support 13 is fixedly connected to one end of the fixed base 14. The support 13 is fixedly connected to the base 1. The support 13 supports and fixes the fixed base 14, and is used to raise the fixed base 14 to a certain height. A sliding groove is opened inside the fixed base 14. The sliding rod 15 is U-shaped. One end of the sliding rod 15 slides in the sliding groove. A drive assembly for driving the sliding rod 15 to slide is fixedly connected to the support 13. The drive assembly is used to mechanically drive the sliding rod 15 to slide, control the sliding rod 15 to slide out of the sliding groove, or pull the sliding rod 15 back into the sliding groove.

[0026] The drive assembly includes a bracket 17, which is fixedly connected to the support 13. An electric push rod 16 (model AUM3-S-24-100) is fixedly connected inside the bracket 17. The output end of the electric push rod 16 is inserted into the slide groove and is fixedly connected to the slide rod 15. The output end of the electric push rod 16 can extend or retract to push or pull the slide rod 15, so that the end of the slide rod 15 extends out of the fixed seat 14 or is retracted into the fixed seat 14.

[0027] Multiple sets of support rods 2 are provided, and the lifting seat 5 is slidably installed on multiple sets of support rods 2. The multiple sets of support rods 2 are used to stabilize the lifting seat 5 and play a good guiding role. Multiple sets of lubrication sleeves 20 for adding lubricating oil are fixed on the lifting seat 5. The lubrication sleeve 20 has an oil cavity and a hole at the upper end. Lubricating oil is added into the oil cavity through the hole. When the lifting seat 5 drives the lubrication sleeve 20 to rise and fall, the lubrication sleeve 20 slides against the side wall of the support rod 2, and the lubricating oil is applied to the support rod 2, so as to avoid wear between the support rod 2 and the lifting seat 5 due to long-term use.

[0028] Multiple sets of guide cylinders 10 are fixedly connected to the lower end of the lifting seat 5, and multiple sets of limiting seats 7 are fixedly connected to the upper end of the base 1. Guide rods 9 are fixedly connected to the upper end of each set of limiting seats 7, and the multiple sets of guide rods 9 are slidably inserted into the multiple sets of guide cylinders 10 respectively.

[0029] When the lifting seat 5 descends, the guide rod 9 is inserted into the guide cylinder 10, and the limiting seat 7 limits the descent of the guide cylinder 10 to prevent the stamping seat 8 from excessively stamping the spline shaft 12 to be tested.

[0030] Multiple sets of vertical rods 18 are fixedly connected to the upper end of the base 1. Each set of vertical rods 18 has a safety light curtain (model 19GL-R08H-CzD) fixedly connected to its side wall. The multiple sets of safety light curtains 19 work together and are located at the front end of the device to prevent workers from accidentally entering the device and getting injured, effectively ensuring the safety of personnel and equipment.

[0031] The working principle of the spline shaft stamping device provided by this utility model is as follows:

[0032] The spline shaft to be processed is placed on the processing seat 11. The output end of the electric push rod 16 pushes the slide rod 15 out of the slide groove, so that the crossbeam part of the slide rod 15 moves directly above the spline shaft body. The hydraulic cylinder 4 is activated, pushing the lifting seat 5 to move downward along the support rod 2, driving the stamping seat 8 and the stamping tool at its bottom to complete the stamping operation on the spline shaft. After the stamping is completed, the hydraulic cylinder 4 drives the lifting seat 5 to rise. If the stamping tool sticks to the spline shaft, the spline shaft will be lifted. However, since the U-shaped slide rod 15 is already above it, the spline shaft will only be lifted a small distance before hitting the crossbeam of the slide rod 15, thus being forcibly blocked and separated from the tool, falling back to the processing seat 11. After the lifting seat 5 is fully reset, the electric push rod 16 retracts, pulling the U-shaped slide rod 15 back to its original position, making room above the spline shaft. The operator or robot can then safely remove the processed spline shaft, solving the problem of the spline shaft being lifted and realizing continuous automated operation of production.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
