[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-6 As shown, a drilling device for a solenoid valve seat includes a drilling machine 2 for drilling and a base 1 for adjusting the position of the drilling machine 2. The drilling machine 2 is mounted on the base 1. It also includes a clamping mechanism 4 for fixing the valve seat 6, an auxiliary mechanism 5 for reducing vibration during drilling, and a lateral adjustment mechanism 3 for auxiliary positioning. The lateral adjustment mechanism 3 is mounted on the lower side of the drilling machine 2. The clamping mechanism 4 is mounted on the transverse sliding seat 32 of the lateral adjustment mechanism 3. The auxiliary mechanism 5 is mounted on the upper side of the clamping mechanism 4. The drill bit 21 is mounted on the drilling machine 2 and its lower end is connected through to the rotating sleeve 52 of the auxiliary mechanism 5.

[0030] The lateral adjustment mechanism 3 includes a base 31, a transverse sliding seat 32 slidably connected to the inner side of the base 31, a positioning plate 33 installed on the front side of the transverse sliding seat 32, a fixing plate 34 corresponding to the position of the positioning plate 33 on the base 31, a plug 35 slidably connected to the fixing plate 34, and a positioning groove 331 correspondingly provided on the positioning plate 33.

[0031] The clamping mechanism 4 includes a fixed chuck 41, a chuck limiting seat 42 is provided on one side of the fixed chuck 41, a movable chuck 43 is slidably connected to the chuck limiting seat 42 on the side corresponding to the fixed chuck 41, an irregular extrusion block 45 is provided on the side of the movable chuck 43 away from the fixed chuck 41, and a wrench 44 is connected to the upper end of the irregular extrusion block 45. The auxiliary mechanism 5 includes a long rod 51, a rotating sleeve 52 is provided on the front side of the long rod 51 corresponding to the position of the drill bit 21, and the rotating sleeve 52 is rotatably connected to the long rod 51 through a shock-absorbing component.

[0032] In this embodiment, the shock absorption assembly includes a release groove 54 and balls 55. Two release grooves 54 are provided on the inner side of the long rod 51, and balls 55 are rolled inside each release groove 54. The rotating sleeve 52 has grooves formed on the balls 55. A compression spring 56 is provided between the upper end of the upper ball 55 and the release groove 54, and a compression spring 56 is provided between the lower end of the lower ball 55 and the release groove 54. Because the vibration during the drilling process is diffused outward, the two release grooves 54 and the compression springs 56 are symmetrically arranged. When the vibration is transmitted to the rotating sleeve 52 through the lubricant, the vibration will diffuse upward and downward, and the rotating sleeve 52 and the balls 55 will rotate accordingly, thereby consuming the vibration force and eliminating the vibration diffusion.

[0033] In this embodiment, the drill bit 21 is connected through the hole 53 on the rotating sleeve 52. The drill bit 21 is fitted with the rotating sleeve 52 with clearance. The inside of the hole 53 is coated with lubricating oil. The damping of the lubricating oil can transmit vibration and prevent jamming.

[0034] In this embodiment, the front end of the positioning groove 331 is chamfered, and the plug 35 is rounded at one end corresponding to the positioning groove 331, which improves the fitting effect.

[0035] In this embodiment, the fixed clamp 41 is connected to the transverse sliding seat 32 by bolts and positioning pins.

[0036] In this embodiment, the narrow end of the irregular extrusion block 45 is connected to a rotating shaft, the rotating shaft is connected through the chuck limiting seat 42, and the top of the rotating shaft is connected to a wrench 44.

[0037] In this embodiment, the fixed clamp 41 and the movable clamp 43 both have V-shaped openings formed on their corresponding end faces.

[0038] Working principle: When the valve seat 6 needs to be precision machined, select the appropriate clamping mechanism 4 and positioning plate 33 according to the position of the valve seat 6 and the drill hole on the valve seat 6. After replacement, start the drilling machine 2 to make the drill bit 21 rotate, and control the machine base 1 to drive the drilling machine 2 and the drill bit 21 to drill down.

[0039] During drilling, the drill bit 21 is subjected to bidirectional compression due to pressure at the top and resistance at the bottom. Due to its slender structure, it experiences vibration in the central part. Since the vibration during drilling is diffused outward, the two release grooves 54 and the compression springs 56 are symmetrically arranged. When the vibration is transmitted to the rotating sleeve 52 through the lubricant, the vibration will diffuse upward and downward. The upper and lower compression springs 56 will diffuse and consume the vibration. The rotating sleeve 52 and the ball bearing 55 will rotate along with it, thereby consuming the vibration force and eliminating the vibration diffusion. This prevents the vibration from affecting the drilling accuracy. After drilling one hole, the ball bearing 55 can be moved quickly to move the transverse seat 32 and the valve seat 6 to perform the drilling operation for the second hole.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
