Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a high-pressure mud pump cylinder liner machining and grinding device, comprising,

[0028] The system includes an operating table 101, a guide rail 102 fixedly mounted on the side wall of the operating table 101, a connection hole 103 opened on the top of the operating table 101, a mounting bracket 104 fixedly mounted on the bottom of the operating table 101, a clamping assembly 105 disposed on the outer surface of the operating table 101, and a drive assembly 106 disposed on the outer surface of the mounting bracket 104 for use with the clamping assembly 105.

[0029] Specifically, the clamping assembly 105 includes a cylinder 105a fixedly mounted on the side wall of the operating table 101, a mounting block 105b fixedly mounted on the end of the cylinder 105a, an outer grinding stone 105c snapped into the side wall of the mounting block 105b, and a limiting groove 105d formed on the side wall of the outer grinding stone 105c.

[0030] Furthermore, cylinders 105a are symmetrically arranged on both sides of the operating table 101, and a limit groove 105d is also provided on the mounting block 105b. The limit groove 105d is used in conjunction with the guide rail 102 to ensure that the running path of the mounting block 105b is fixed when the cylinder 105a pushes the mounting block 105b.

[0031] The drive assembly 106 includes a motor 106a fixedly mounted on the outer surface of the mounting bracket 104, a ratchet 106b sleeved on the output end of the motor 106a, a pawl 106c movably connected to the outer surface of the ratchet 106b, and a winding spring 106d fixedly connected to the inner wall of the pawl 106c. The drive assembly 106 also includes a fixing post 106e fixedly connected to the end of the winding spring 106d, a connecting disc 106f fixedly mounted on the end of the fixing post 106e, and an abutment member 106g disposed at the output end of the motor 106a.

[0032] Preferably, motor 106a is a servo motor 106a, which can precisely control the direction of rotation of motor 106a. When motor 106a rotates in the forward direction, pawl 106c will lock ratchet 106b, and ratchet 106b will drive connecting disk 106f to rotate. When motor 106a rotates in the reverse direction, pawl 106c, together with winding spring 106d and fixing post 106e, will be pushed away by ratchet 106b to ensure that connecting disk 106f will not rotate.

[0033] The abutting component 106g includes an adjustment box 106f-1 fixedly installed at the output end of the motor 106a, a transmission auger 106f-2 connected to the inner cavity of the adjustment box 106f-1 via a bearing, a transmission housing 106f-3 meshing with the outer surface of the transmission auger 106f-2, and the abutting component 106g also includes a connector 106f-4 fixedly installed on the side wall of the transmission housing 106f-3, a transmission gear 106f-5 fixedly installed on the side wall of the connector 106f-4, a rack 106f-6 meshing with the outer surface of the transmission gear 106f-5, and an inner grinding stone 106f-7 fixedly installed at the end of the rack 106f-6.

[0034] Furthermore, the connector 106f-4 can transfer the force on the transmission housing 106f-3 to the transmission gear 106f-5. The transmission housings 106f-3 are symmetrically arranged on both sides of the transmission auger 106f-2. The two transmission housings 106f-3 rotate in opposite directions, ensuring that the two transmission gears 106f-5 move in opposite directions, thus driving the rack 106f-6 to move in opposite directions. The inner grinding stone 106f-7 will abut against the inner wall of the cylinder liner, thereby processing the inner wall.

[0035] It should be noted that the side wall of the connecting plate 106f is slidably connected to the inner cavity of the connecting hole 103, and the inner wall of the connecting plate 106f is connected to the output end of the motor 106a through a bearing.

[0036] In use, the cylinder liner is placed on the connecting plate 106f. The drive auger 106f-2 is turned, causing the drive housing 106f-3 to rotate. The drive housing 106f-3 then drives the drive gear 106f-5 to rotate, which in turn drives the rack 106f-6 to move back and forth until it abuts against the inner wall of the cylinder liner. The cylinder 105a then operates, causing the mounting block 105b and the outer grinding stone 105c to clamp the cylinder liner. The motor 106a rotates forward, and the pawl 106c engages the ratchet 1 on the output end of the motor 106a. 06b, the ratchet 106b, in conjunction with the pawl 106c, drives the connecting plate 106f to rotate. The rotation of the connecting plate 106f, in conjunction with the abutment device, drives the cylinder liner to rotate. The outer grinding stone 105c polishes the outer surface of the cylinder liner. After the outer surface is polished, the motor 106a reverses. The pawl 106c, in conjunction with the coiling spring 106d, will spring the pawl 106c away when the ratchet 106b rotates, ensuring that the connecting plate 106f does not rotate. The motor 106a drives the abutment component 106g to rotate, and the clamping component 105 clamps the cylinder liner. The rotation of the abutment component 106g polishes the inner wall of the cylinder liner.

[0037] In summary, the precise grinding of the inner and outer surfaces of the cylinder liner is achieved through the cooperation of the clamping assembly 105 and the drive assembly 106. The linkage of the transmission auger 106f-2, transmission housing 106f-3, transmission gear 106f-5, and rack 106f-6 ensures the smoothness and precision of the grinding process. The cooperation of the cylinder 105a, mounting block 105b, and outer grinding stone 105c ensures the stable clamping of the cylinder liner. The forward and reverse rotation of the motor 106a and the ingenious design of the ratchet 106b, pawl 106c, and connecting plate 106f not only make the outer surface of the cylinder liner uniformly ground, but also keep the connecting plate 106f fixed when grinding the inner wall, thereby improving grinding efficiency and precision, reducing processing errors, extending the service life of the cylinder liner, and ensuring the smooth progress of drilling operations.
