Description

Technical Field

[0001] The utility model mainly relates to the technical field of mechanical clamping jaws, in particular to a clamping jaw which can self-level a ring-shaped material with an inner hole cone surface. Background Art

[0002] Before the machining center processes the ring-shaped material with the inner cone surface, the ring-shaped material is generally placed on the tooling of the machining center using a fixture. Conventional fixtures clamp the ring-shaped material from the hole and outside of the inner cone hole to reduce the structural size of the equipment. During the clamping process of the conventional fixture's jaws, the ring-shaped material will be skewed on the fixture, and the skewed ring-shaped material cannot be relatively vertically assembled on the tooling of the machining center.

[0003] The inventor proposed a clamping jaw that can self-level the inner cone surface ring-shaped material. The structure of the clamping jaw was redesigned to adapt to the inner cone surface of the inner cone surface ring-shaped material. At the same time, it can also clamp the ring-shaped material with a conventional cylindrical surface, thereby increasing the clamping compatibility design of the clamp with the material.

[0034] See attached Figure 1-4 The utility model provides a clamping jaw for self-leveling a material with an inner conical surface, comprising the following structure:

[0035] The arm fixing plate 1 has a double-acting cylinder 2 fixedly arranged at the bottom thereof, and a pressing plate 3 fixedly arranged at the bottom thereof.

[0036] A fixed shaft 4 is provided, wherein the front end of the fixed shaft 4 is movably connected to a pin shaft 5 , and the middle part of the pin shaft 5 is movably connected to a movable block 6 .

[0037] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a connecting plate 31 is fixedly provided on the rear side of the pressing plate 3 , and the rear side of the connecting plate 31 is fixedly connected to the moving end of the linear guide rail 32 .

[0038] The design of the connecting plate 31 and the linear guide rail 32 improves the movement stability of the pressing plate 3 when driven by the compound cylinder 2 .

[0039] In this embodiment, Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, a fixing plate 7 is inserted into the rear end of the fixing shaft 4 , the top of the fixing plate 7 is fixedly connected to the bottom rear side of the arm fixing plate 1 , and the front top of the fixing plate 7 is fixedly connected to the guide rail of the linear guide rail 32 .

[0040] The fixing plate 7 is used to fix the shaft 4 and the linear guide rail 32 , and the fixing plate 7 cooperates with the arm fixing plate 1 to complete the assembly of the fixture installation frame.

[0041] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rubber pad 61 is fixedly disposed on the top of the movable block 6 , and the bottom of the movable block 6 abuts against the top of the fixed shaft 4 .

[0042] The design of the rubber pad 61 prevents the movable block 6 of the clamping device from damaging the inner hole conical surface of the ring-shaped material.

[0043] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a deflection surface is obliquely provided at the top of the front end of the fixed shaft 4 , and the deflection surface faces the bottom of the movable block 6 .

[0044] The deflection surface design of the fixed shaft 4 facilitates the movable block 6 to cooperate with the pin shaft 5 to deflect in front of the fixed shaft 4 when the rubber pad 61 on the movable block 6 contacts the inner hole cone surface of the ring-shaped material, and the deflection surface provides limiting support for the movable block 6 after deflection.

[0045] Specific operation process:

[0046] The robot arm cooperates with the arm fixed plate 1 to work, the fixed shaft 4 is inserted into the inner hole cone surface of the ring-shaped material, the rubber pad 61 on the movable block 6 contacts the inner hole cone surface of the ring-shaped material, the floating guide rail cooperates with the pressure plate 3 to contact from the outside of the ring-shaped material, the pressure plate 3 and the rubber pad 61 cooperate to complete the clamping and release of the inner hole cone surface ring-shaped material, so that the material taking and releasing mechanism coordinated by the equipment and the robot arm is not affected by the different angles of the inner hole of the inner hole cone surface ring-shaped material and can be smoothly clamped and released, ensuring that the inner hole cone surface ring-shaped material is relatively vertical so that the machine tool spindle can be smoothly clamped and processed, so that the parts meet the processing requirements.

[0047] When the clamping device clamps the ring-shaped material with a conventional cylindrical inner hole, the movable block 6 does not deflect on the fixed shaft 4, thereby completing the compatible clamping and release of the ring-shaped material with a cylindrical inner hole by the device.

[0048] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
