Description

Technical Field

[0001] The utility model relates to the technical field of tappet processing, in particular to a sampling clamp. Background Art

[0002] After the tappet is machined, it is often necessary to perform nitriding treatment to improve its strength and wear resistance. During the treatment, the tappet needs to be placed as follows: Figure 2 On the rotating column on the top, a plurality of inlaid circular grooves are opened on the circumference of the rotating column, and a magnetic rod is arranged in the inlaid circular groove to fix the tappet. During the nitriding treatment, the rotating column rotates continuously to improve the uniformity of nitriding. After nitriding, since the tappet is embedded deeply, it is inconvenient to remove it, which brings some troubles to the subsequent operation of the tappet. Utility Model Content

[0003] The utility model provides a sampling clamp to solve the deficiencies of the prior art and the problem that the tappet is inconvenient to take out, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A sampling clamp includes a middle plate, a plurality of side plates are arranged on the outer periphery of the middle plate, a rotating seat is installed on the side plate, a rotating head is rotatably arranged on the outer end of the rotating seat, a clamp is arranged on the outer end of the rotating head, a spring is arranged on the side plate, the other end of the spring acts on the inner wall of the clamp, the inner wall of the outer end of the clamp is formed with an inclined surface, the outer end of the inclined surface extends outwardly, a movable rod is passed through the middle plate, a push plate is arranged on the outer end of the movable rod, a second spring is arranged between the push plate and the middle plate, and the second spring is sleeved on the movable rod. A pair of convex plates are symmetrically arranged on the middle plate, a concave rod is arranged on the convex plate, an inner end of the inner end of the inner end of the connecting plate is provided with a rotating lug, a push plate is rotatably arranged on the rotating lug, and the inner end of the push plate acts on the outer wall of the push plate. When the push plate rotates, the push plate can move inward, and when the push plate moves, the clamp can rotate inward, and then the inner side of the tappet is clamped by the inner end of the clamp, so as to facilitate the removal operation of the tappet. In order to facilitate the automatic opening of the splint, a spring is also provided.

[0006] Furthermore, a clamping head is provided at the inner end of the clamping plate, and the inner wall of the clamping head is formed with a concave arc surface. The arrangement of the clamping head can improve the stability of clamping and avoid clamping damage to the tappet.

[0007] Furthermore, an arcuate surface is formed on the outer circumference of the push plate, and the outer circumference of the arcuate surface is tangent to the inclined surface. The setting of the arcuate surface can make the inclined surface and the push plate in point contact, thereby reducing the flexibility of the push plate when moving, and also improving the high responsiveness of the rotation of the clamping plate.

[0008] Furthermore, in order to prevent the second spring from causing the movable rod to excessively move outward, an inner plate is provided at the inner end of the movable rod.

[0009] Furthermore, in order to facilitate the rotation operation of the push plate and the clamping operation, an arc-shaped protrusion is provided on the outer wall of the push plate, the outer wall of the arc-shaped protrusion is an arc surface, and the inner end of the push plate acts on the outer wall of the arc-shaped protrusion.

[0010] Furthermore, in order to facilitate the rotation operation of the push plate, the push plate is configured as a T-shaped structure.

[0011] The advantages of the above technical solution are:

[0012] The utility model can conveniently clamp and take out the tappet after the nitriding of the tappet is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0015] Figure 2 A three-dimensional structural diagram of the existing tappet nitriding is shown. DETAILED DESCRIPTION

[0016] like Figure 1~Figure 2As shown, a sampling clamp includes a middle plate 1, a plurality of side plates 10 are arranged on the outer periphery of the middle plate 1, a rotating seat 11 is installed on the side plate 10, a rotating head 12 is rotatably arranged on the outer end of the rotating seat 11, a clamping plate 13 is arranged on the outer end of the rotating head 12, a clamping head 14 is arranged on the inner end of the clamping plate 13, and the inner wall of the clamping head 14 is formed with an inner concave arc surface, a spring 15 is arranged on the side plate 10, the other end of the spring 15 acts on the inner wall of the clamping plate 13, an inclined surface 16 is formed on the inner wall of the outer end of the clamping plate 13, and the outer end of the inclined surface 16 extends outwardly. A movable rod 2 is passed through the middle plate 1, a push plate 22 is arranged on the outer end of the movable rod 2, an arc surface 23 is formed on the outer periphery of the push plate 22, and the outer periphery of the arc surface 23 is tangent to the inclined surface 16, a second spring 21 is arranged between the push plate 22 and the middle plate 1, and the second spring 21 is sleeved on the movable rod 2, and an inner plate 20 is arranged on the inner end of the movable rod 2. A pair of convex plates 3 are symmetrically provided on the middle plate 1, a concave rod 30 is provided on the convex plate 3, an inner extending connecting plate 31 is provided on the concave rod 30, a rotating lug 32 is provided on the inner end of the inner extending connecting plate 31, a push plate 33 is rotatably provided on the rotating lug 32, the inner end of the push plate 33 acts on the outer wall of the push plate 22, an arc-shaped convex portion 24 is provided on the outer wall of the push plate 22, the outer wall of the arc-shaped convex portion 24 is an arc surface, and the inner end of the push plate 33 acts on the outer wall of the arc-shaped convex portion 24, and the push plate 33 has a T-shaped structure.

[0017] During operation of this embodiment, the operator takes the rotating column out of the nitriding treatment device.

[0018] Then the operator sleeves the clamping head 14 onto the outer side end of the tappet.

[0019] Then the operator rotates the push plate 33. When the push plate 33 rotates, its inner end will act on the push plate 22, thereby causing the push plate 22 to move inward. As the push plate 22 moves inward, the push plate 22 will move inward. As the push plate 22 moves, the arc-shaped surface 23 of its outer wall will act on the inclined surface 16, thereby causing the clamping head 14 at the inner end of the clamping plate 13 to rotate inward, thereby causing the outer end of the push column to be pressed through the clamping head 14.

[0020] Finally, the operator pulls out the tappet and then rotates the push plate 33 outward, whereupon the push plate 22 moves outward under the action of the second spring 21, and at the same time the clamping head 14 returns to its initial position under the action of the spring 15, and then the tappet is clamped and removed.

[0021] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
