Description

Technical Field

[0001] This utility model relates to the field of valve stem processing technology, specifically a fixture for valve stem processing. Background Technology

[0002] Valves are widely used in daily life. The valve stem is a crucial component of a valve, used for rotation. It connects to the actuator or handle at the top and directly drives the valve core to move or rotate, thereby opening and closing the valve or performing a regulating function. The machining of the valve stem is an important process, requiring the use of fixtures.

[0003] Existing clamps typically hold and fix the valve stem before processing. However, in actual use, it is not quick and easy to hold and fix the valve stem, and it is prone to shaking after being held and fixed, which reduces the working efficiency of the clamp.

[0004] Therefore, we urgently need to provide a fixture for machining valve stems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamp for valve stem processing, so as to solve the problems mentioned in the background art, which are that the clamp cannot be quickly and conveniently clamped and fixed, and that it is easy to shake after clamping and fixing, thereby reducing the working efficiency of the clamp.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for processing valve stems, comprising a connecting plate, a fixture body provided on one side of the connecting plate, one end of the fixture body being connected to one side of the connecting plate, a rotating pressure plate provided inside the fixture body, one end of the rotating pressure plate being movably connected to the inside of the fixture body, and a screw provided inside the fixture body, one end of the screw being movably connected to the inside of the fixture body.

[0007] A further improvement is that a wing nut is provided on the outer wall of the screw, and the inner wall of the wing nut is threadedly connected to the outer wall of the screw. A cross roller guide is provided on the inner wall of the clamping body, and one side of the cross roller guide is connected to the inner wall of the clamping body, so as to better clamp and fix the valve stem, and better position and fix the valve stem.

[0008] A further improvement is that an adjustment box is provided at one end of the clamping body, one side of the adjustment box is connected to one end of the clamping body, a sliding plate is provided on the inner wall of the adjustment box, both ends of the sliding plate are slidably connected to the inner wall of the adjustment box, a limit rod is provided on one side of the sliding plate, and one end of the limit rod is connected to one side of the sliding plate.

[0009] A further improvement is that a mounting plate is provided at one end of the limiting rod, one side of the mounting plate is connected to one end of the limiting rod, and a limiting ball is provided on the other side of the mounting plate. The outer side of the limiting ball is movably connected to the other side of the mounting plate, thereby enabling better positioning and fixing of the valve stem, and thus better clamping and fixing.

[0010] A further improvement is that a pull rod is provided on one side of the sliding plate, one end of the pull rod is connected to one side of the sliding plate, a spring is fixedly installed between one side of the sliding plate and the inner wall of the adjusting box, and a valve stem is provided on one side of the cross roller guide rail.

[0011] A further improvement is that the number of adjustment boxes is three, and the adjustment boxes are symmetrically distributed at one end of the clamping body. The number of limiting balls is three, and the limiting balls are symmetrically distributed at one end of the three adjustment boxes, so as to better position and fix the valve stem, and thus better clamp and fix it.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution:

[0021] A fixture for processing valve stems includes a connecting plate 1, a fixture body 2 is provided on one side of the connecting plate 1, one end of the fixture body 2 is connected to one side of the connecting plate 1, a rotating pressure plate 3 is provided inside the fixture body 2, one end of the rotating pressure plate 3 is movably connected to the inside of the fixture body 2, and a screw 4 is provided inside the fixture body 2, one end of the screw 4 is movably connected to the inside of the fixture body 2.

[0022] The outer wall of the screw 4 is provided with a wing nut 5, and the inner wall of the wing nut 5 is threadedly connected to the outer wall of the screw 4. The inner wall of the clamping body 2 is provided with a cross roller guide 6, and one side of the cross roller guide 6 is connected to the inner wall of the clamping body 2, so as to better clamp and fix the valve stem 13 and better position and fix the valve stem 13.

[0023] One end of the clamping body 2 is provided with an adjustment box 7. One side of the adjustment box 7 is connected to one end of the clamping body 2. A sliding plate 8 is provided on the inner wall of the adjustment box 7. Both ends of the sliding plate 8 are slidably connected to the inner wall of the adjustment box 7. A limit rod 9 is provided on one side of the sliding plate 8. One end of the limit rod 9 is connected to one side of the sliding plate 8.

[0024] One end of the limiting rod 9 is provided with a mounting plate 10. One side of the mounting plate 10 is connected to one end of the limiting rod 9. The other side of the mounting plate 10 is provided with a limiting ball 11. The outer side of the limiting ball 11 is movably connected to the other side of the mounting plate 10, so as to better position and fix the valve stem 13, and thus better clamp and fix it.

[0025] A pull rod 12 is provided on one side of the sliding plate 8. One end of the pull rod 12 is connected to one side of the sliding plate 8. A spring is fixedly installed between one side of the sliding plate 8 and the inner wall of the regulating box 7. A valve stem 13 is provided on one side of the cross roller guide rail 6.

[0026] There are three regulating boxes 7, which are symmetrically distributed at one end of the clamping body 2. There are also three limiting balls 11, which are symmetrically distributed at one end of the three regulating boxes 7, so as to better position and fix the valve stem 13, and thus better clamp and fix it.

[0027] When needed, the operator fixes the connecting plate 1 to the external equipment, inserts the valve stem 13 into the clamping body 2, and uses the cross roller guide 6 for better positioning and guidance. After the valve stem 13 is inserted into the clamping body 2, the operator pulls the rotating pressure plate 3 and the screw 4 to swing, causing the rotating pressure plate 3 to press against the valve stem 13, and the screw 4 to insert into the inside of the rotating pressure plate 3. The operator then rotates the wing nut 5, causing it to move on the screw 4, thus pressing against the rotating pressure plate 3 and limiting and fixing it, thereby limiting and fixing the valve stem 13. This provides better clamping and fixing of the valve stem 13. When the valve stem 13 is inserted into the clamping body 2, it compresses and moves the limiting ball 11. The mounting plate 10 is moved, which in turn moves the limiting rod 9. The limiting rod 9 then moves the sliding plate 8 against the inner wall of the regulating box 7. The sliding plate 8 compresses the spring, thus providing better positioning and guidance when the valve stem 13 is inserted into the clamping body 2. After the valve stem 13 is inserted and clamped, the spring force resets the limiting ball 11, which better limits and fixes the valve stem 13, allowing for better processing. When the valve stem 13 needs to be removed, the pulling rod 12 is moved, which in turn moves the sliding plate 8. The movement of the sliding plate 8 indirectly moves the limiting ball 11, thus releasing the limiting fixation of the valve stem 13 and allowing it to be removed.
