Description

Technical Field

[0001] This utility model relates to the field of water valve manufacturing technology, specifically to a drilling device for valve stems. Background Technology

[0002] In the industrial manufacturing field, the valve stem is a key component of the valve, and its machining accuracy and efficiency directly affect the overall performance of the valve. Especially when drilling is required for the valve stem, the limitations of traditional machining methods gradually become apparent.

[0003] Traditional valve stem drilling processes typically rely on manual clamping devices, such as bench vises, to manually adjust and fix the valve stem position to complete the drilling operation. However, this method has many problems, such as low efficiency, high labor intensity, insufficient positioning accuracy, and limited applicability. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for a valve stem, comprising a vertical plate, a back block fixed to the back of the vertical plate, side blocks fixed to both sides, and two sets of plates fixed thereon. Clamping blocks are inserted through the plates, and a spring connected to the corresponding side block is fixed to one end of each clamping block. A movable block is formed on one side of each clamping block and inserted through the vertical plate. A lifting assembly is installed on the back block, and a squeezing block located between the two movable blocks is fixed in the middle of the lifting end of the lifting assembly, and a pressure block located above the two clamping blocks is fixed at the top.

[0005] Furthermore, the side of the moving block that is in contact with the extrusion block is inclined, and both sides of the extrusion block are arc-shaped.

[0006] Furthermore, the lifting assembly includes an ejector cylinder fixed to the back block and a lifting plate that passes through the back block and is fixed to the piston rod of the ejector cylinder. The extrusion block and the pressure block are both mounted on the lifting plate.

[0007] Furthermore, a rubber block is also installed at the bottom of the pressure block.

[0008] Furthermore, a guide block extending between the two clamping blocks is fixed to the top of the upright plate, and a placement hole is provided on the guide block.

[0009] Furthermore, the top of the guide block has two side plates fixed, and a push block located below the two side plates is slidably connected to it. The top of the upright plate is equipped with a propulsion cylinder connected to the push block.

[0010] Furthermore, a baffle is formed on the top of the upright plate, which is opposite to the push block, and a protrusion is formed on the baffle between the two clamping blocks.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The valve stem drilling device inserts the valve stem into the placement hole of the guide block, and then the lifting assembly moves down, which drives the pressure block to press down and fix the valve stem. At the same time, the lifting plate moves along with it, causing the extrusion block to separate from the moving block. Therefore, under the elastic force of the spring, the clamping block will be pushed to clamp and fix the valve stem. Meanwhile, the push cylinder pushes the push block to cooperate with the baffle, which can also fix the valve stem. Thus, the automation process reduces manual intervention, improves efficiency and reduces operational risks. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4This embodiment of a valve stem drilling device includes a vertical plate 1. The vertical plates of the vertical plate 1 are combined in a T-shape. A back block 10 is fixed to the back of the vertical plate 1. An ejector cylinder 11 is installed on the plate surface of the back block 10. A lifting plate 12 that passes through the back block 10 is fixed to the ejector end of the ejector cylinder 11. A pressure block 13 is fixed to the top of the lifting plate 12, and a squeezing block 14 is fixed to the middle. A rubber block is fixed to the bottom of the pressure block 13. Side blocks 7 are fixed to both sides of the vertical plate 1, and two sets of oppositely distributed plates 6 are fixed to the front. A spring 8 is fixed to the opposite side of the side blocks 7. A clamping block 9 is slidably connected to the inner side of the plate 6. The tail end of the clamping block 9 is fixed to the spring 8. A movable block 15 that passes through the vertical plate 1 is formed on the back of the clamping block 9. The squeezing block 14 is located between the movable blocks 15.

[0020] In the above structure, in the initial state, the piston rod of the ejector cylinder retracts, and the lifting plate drives the pressure block to rise. The squeezing block then presses against the two moving blocks, causing them to move in opposite directions. As a result, the clamping block compresses the spring. The valve rod is then placed vertically between the upright plate and the pressure block. The ejector cylinder ejects, causing the pressure block to press the valve rod down and position it. At the same time, the rubber block provides cushioning, preventing the pressure block from damaging the top of the valve rod and increasing friction to indirectly improve the stability of the fixation. Simultaneously, the squeezing block separates from the moving blocks, and under the elastic force of the spring, pushes the clamping block to clamp both sides of the valve rod, thus completing the drilling operation on the valve rod.

[0021] The extrusion block 14 has rounded sides, and the movable block 15 passes through the vertical plate 1 and can move within it. The position where the movable block 15 is in contact with the extrusion block 14 is inclined. Therefore, when the extrusion block is raised or lowered, the curved shape and the inclined part of the movable block can be matched to facilitate the movement of the movable block by extrusion.

[0022] In addition, a guide block 2 is installed on the upright plate 1. The head end of the guide block 2 extends to the bottom of the two clamping blocks 9. The clamping blocks 9 are adapted to the guide block 2, and the guide block 2 limits the clamping blocks 9. The head end of the guide block 2 is provided with a placement hole between the two clamping blocks 9, so that the valve stem can be inserted into the placement hole for limitation, and the valve stem can also be placed in the accurate position.

[0023] Meanwhile, two sets of side plates 3 are fixed on the guide block 2, and push blocks 4 are slidably connected to the inside of the guide block 2 below the two sets of side plates 3. A baffle is formed on the top of the upright plate 1 opposite to the push block 4. The baffle has a protrusion, which can also limit the clamping blocks 9 and prevent the two sets of clamping blocks 9 from touching. A push cylinder 5 is also installed on the upright plate 1, and the piston rod of the push cylinder 5 is fixed to the push block 4. Therefore, the push block is moved by the push cylinder until it touches the valve stem, and the clamping is completed with the help of the baffle. This can also improve the clamping and fixing of the valve stem and improve the firmness during the drilling process.

[0024] The working principle of the above embodiments is as follows:

[0025] By inserting the valve stem into the placement hole, the pusher cylinder first moves the push block forward, clamping and fixing the valve stem in cooperation with the baffle. At the same time, the ejector cylinder ejects, causing the lifting plate to rise and fall. The pressure block moves the rubber block to press the valve stem from top to bottom, fixing it in place. Simultaneously, the extrusion block also moves with the lifting plate. At this point, the extrusion block separates from the moving block. Under the push of the spring, the clamping block, guided by the plate, clamps and positions both sides of the valve stem. Therefore, the stability during drilling can be improved by clamping and fixing the valve stem in multiple directions. At the same time, the efficiency can be improved by automated clamping, reducing manual intervention.

[0026] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
