Description

Technical Field

[0001] The utility model specifically relates to a PTFE annular incision tooling. Background Art

[0002] With the continuous development of industry, the quality and performance requirements of automobile engines are getting higher and higher, and there are more and more types, so the requirements for their sealing performance are also getting higher and higher. Based on this requirement, especially for the sealing of camshafts, some companies use PTFE rings with higher performance to achieve their functions. Compared with traditional oil seals, PTFE rings are lighter in weight and have special structure cuts on their surfaces. This can not only ensure its sealing performance, but also meet the pressure relief through the cuts. Thereby ensuring the efficiency and stability of the engine system.

[0003] However, there are few existing PTFE ring products, and different incision processing is required. For special product materials, special product incision shapes and sizes, the cutter position is manually adjusted one by one, and the incision is performed based on experience. The incision position is difficult to grasp, the yield rate is low, and the processing efficiency is poor. For this reason, we propose a PTFE ring incision tooling. Utility Model Content

[0009] Preferably, three guide rods are provided, and the top ends of the three guide rods are provided with plates for connecting into a whole.

[0010] Preferably, the rotation adjustment assembly includes an adjustment block, a locking bolt, a clamping plate and a clamping bolt, the adjustment block is rotatably installed on one end of the pressure plate, and the adjustment block is connected to a locking bolt for locking it through a threaded fit, and the locking bolt is in contact with the pressure plate, the lower surface of the adjustment block is provided with a mounting groove that cooperates with the cutter, and the clamping plate is arranged on the inner side of the mounting groove, the clamping bolt is arranged on a side wall of the adjustment block, and the clamping bolt clamps the cutter by contacting the clamping plate.

[0011] Preferably, the cross section of the cutter is T-shaped.

[0012] Preferably, the pressure plate is provided with scales, and the scales are distributed along the circumference of the adjustment block.

[0013] Preferably, a connecting rod cooperating with an external press is fixed on the pressing plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By providing a base, a positioning column, a guide rod, a slider and a pressure plate, it is avoided that when cutting the PTFE ring, manual cutting with a blade is required, the cutting position is difficult to grasp, and the yield rate is low. The device can well ensure the position of the cutter, thereby achieving a uniform cut, and is easy to operate, convenient to improve production efficiency, and easy to use.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a PTFE ring incision tool, comprising:

[0024] A base 1, on which a guide rod 31 is fixed, and a slider 32 is sleeved on the guide rod 31, so that the pressing plate 4 can move vertically up and down;

[0025] The pressing plate 4 is detachably mounted on the slider 32, and one end of the lower surface of the pressing plate 4 is connected to a cutter 5 for cutting through a rotary adjustment assembly, so that the position of the cutter 5 can be adjusted to achieve different cuts as needed;

[0026] The positioning column 2 is fixed to one end of the base 1 to facilitate the positioning and placement of the PTFE ring 7, and the outer surface of the positioning column 2 is sleeved with the PTFE ring 7.

[0027] In this embodiment, preferably, three guide rods 31 are provided, and the top ends of the three guide rods 31 are provided with plates for connecting into a whole, so as to form a whole and improve the guiding effect on the pressure plate 4.
