Description

Technical Field

[0001] The utility model relates to the technical field of valve cover processing, in particular to a processing fixture for the valve cover. Background Art

[0002] The valve cover is a valve part equipped with a valve stem seal, which is used to connect or support the actuator. The valve cover and the valve body can be an integral whole or can be separated. During the processing of the valve cover, it is usually necessary to clamp and fix the valve cover with a fixture.

[0003] When clamping and fixing the valve cover, the existing clamp usually uses a clamping arm to clamp and fix the valve cover, and drills the top of the valve cover. However, there is usually a certain curvature on the surface of the valve cover, which causes the clamping arm to slip easily during the process of clamping, fixing and processing the valve cover, and it is impossible to clamp and fix the valve cover stably. For this reason, we propose a valve cover processing fixture. Utility Model Content

DETAILED DESCRIPTION

[0022] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] like Figure 1-Figure 4 As shown, a valve cover processing fixture includes a mounting base plate 1, connecting legs 2 are symmetrically provided at both ends of the mounting base plate 1, fixed support blocks 3 are symmetrically provided on the top of the mounting base plate 1, an adjusting clamping mechanism 4 is fixedly connected to the middle of the top end of the mounting base plate 1, and a quick-release clamping mechanism 5 is movably connected inside the adjusting clamping mechanism 4.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, by adjusting the adjusting clamping mechanism 4 and driving the quick-release clamping mechanism 5, the quick-release clamping mechanism 5 can stably clamp and fix the valve cover, so that the valve cover is in a stable state, thereby enabling the valve cover to be in a stable state during the processing process and easy operation.

[0027] In another embodiment, Figure 3 As shown, the adjustment clamping mechanism 4 includes a connecting guide rail 6 , one end of the connecting guide rail 6 is fixedly connected to an output motor 7 , and an output end of the output motor 7 is fixedly connected to a bidirectional threaded rod 8 .

[0028] The output motor 7 is convenient for driving the bidirectional threaded rod 8 so that the quick-release clamping mechanism 5 can move outside the surface of the bidirectional threaded rod 8, which is easy to operate.

[0029] In another embodiment, Figure 3 As shown, a fixed baffle 9 is fixedly connected to the middle of the top end of the connecting guide rail 6.

[0030] The fixing baffle 9 can improve the use strength of the connecting guide rail 6 and avoid deformation.

[0031] In another embodiment, Figure 4As shown, the quick-release clamping mechanism 5 includes a movable bottom block 10, and the movable bottom block 10 is movably connected to a rotating mounting plate 11 inside. The top of the rotating mounting plate 11 is fixedly connected to an adjusting threaded rod 12, and the top of the adjusting threaded rod 12 is fixedly connected to a rotating handle 13. A movable clamping block 14 is movably sleeved on the outer surface of the adjusting threaded rod 12. A threaded hole 15 is provided at one end of the movable clamping block 14, and a connecting clamping block 16 is movably clamped inside the other end of the movable clamping block 14. One side of the connecting clamping block 16 is fixedly connected to a connecting clamping block 17, and a fixed slot 18 is provided on one side of the connecting clamping block 17. A processing slot 19 is provided on the top of the connecting clamping block 17.

[0032] It is convenient to rotate the rotating handle 13 to drive the adjusting threaded rod 12 and the rotating mounting plate 11 to rotate, so that the movable block 14 can move upward on the outer side of the surface of the adjusting threaded rod 12 under the action of the threaded hole 15, so that the connecting block 16 can be detached from the inner side of the movable block 14, and the connecting block 16 and the connecting clamping block 17 can be disassembled and replaced, which is easy to operate.

[0033] In another embodiment, Figure 4 As shown, the cross-section of the connecting block 16 is T-shaped, and a slot adapted to the connecting block 16 is provided at the bottom of one end of the movable block 14 away from the movable bottom block 10 .

[0034] This facilitates the connection block 16 to be stably clamped on the inner side of the movable block 14 , so that the connection clamping block 17 is in a stable use state, thereby stably clamping and fixing the valve cover.

[0035] In another embodiment, Figure 4 As shown, the movable bottom block 10 and the bidirectional threaded rod 8 are connected via threads, and the outer surface of the movable bottom block 10 and the inner surface of the connecting guide rail 6 are slidably fitted with each other.

[0036] The bidirectional threaded rod 8 can drive the movable bottom block 10 to move when rotating, and the movable bottom block 10 can stably move on the inner side of the connecting guide rail 6, which is easy to operate.

[0037] In another embodiment, Figure 4 As shown, a fixed guide rod 20 is symmetrically provided on the top of the movable bottom block 10 , and a fixed through hole 21 adapted to the fixed guide rod 20 is opened inside one end of the movable clamping block 14 .

[0038] The movable block 14 can stably move up and down on the outside of the surface of the fixed guide rod 20 under the action of the fixed through hole 21 during the lifting process, and the operation is convenient.

[0039] The working principle of the present invention is as follows: during use, the valve cover is placed on the top of the fixed baffle 9, and then the output motor 7 drives the bidirectional threaded rod 8 to rotate. At this time, the movable bottom block 10 can move in opposite directions at the outside of the surface of the bidirectional threaded rod 8 at the same time, driving the rotating mounting plate 11, the adjusting threaded rod 12, the rotating handle 13, the movable clamping block 14, the connecting clamping block 16 and the connecting clamping block 17 to move, clamping and fixing the valve cover, and drilling the valve cover surface located on the inner side of the fixed clamping groove 18 through the processing groove 19. If valve covers of different sizes are processed, the rotating handle 13 is rotated to drive the adjusting threaded rod 12 and the rotating mounting plate 11 to rotate, so that the movable clamping block 14 can move outside the surface of the adjusting threaded rod 12 and the fixed guide rod 20, so that the connecting clamping block 16 can be detached from the inner side of the movable clamping block 14, and then the connecting clamping block 16 and the connecting clamping block 17 are quickly disassembled and replaced. The overall structure is simple and easy to operate.

[0040] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
